AB - The thesis describes the theory and design of a general problem-solving system. The system uses a single general heuristic based on a formal definition of differences within the framework of means/ends analysis and employs tree search during problem solution. A comparison is made with two other systems using means/ends analysis. The conditions under which the system is capable of solving problems are investigated and the efficiency of the system is considered. The system has solved a variety of problems of varying complexity and the difference heuristic appears comparatively accurate for goal-directed search within certain limits.

AB - Pancreatic polypeptide (PP) is a 36 amino-acid residue peptide which has recently been recognised in pancreatic endocrine cells. Although PP has a number of effects on gastrointestinal and pancreatic exocrine function, its physiological function has not been clarified. Studies were undertaken to elucidate four aspects of the physiology and pathophysiology of this candidate hormone. Firstly, factors affecting the release of human PP (hPP) were assessed in healthy subjects; secondly polyacrylamide gel electrophoresis was used to investigate molecular heterogeneity of the peptide; thirdly, the organ uptake and half-life time of endogenous PP was measured in pigs; and finally, basal and stimulated serum hPP concentrations were assayed in patients with acute pancreatitis, chronic pancreatitis and maturity-onset diabetes mellitus.

AB - A quantitative analysis of suitable habitat for the Shoebill (Balaeniceps rex), a large waterbird confined to African swamps, was conducted by using a combination of aerial photographs and a previously determined habitat suitability model from the Bangweulu Wetlands, Zambia. The Shoebill is considered Vulnerable on the IUCN red list, but there are no pre-existing quantitative data on the composition of suitable habitat for this species. Both univariate and multivariate analyses revealed that non-wetland habitats as well as non-vegetated wetland habitats have low suitability compared to vegetated wetland habitats. Notably, reeds correlated significantly and positively with suitability (rs = 0.338, p < 0.001). We found little support for the hypothesis that floating vegetation is highly suitable for Shoebills, but the analysis for this habitat may have suffered as a result of confounding factors. The relationship between flooded grassland and suitability was highly variable and was not significant (rs = 0.009, p = 0.807). In contrast, dry grassland correlated positively with suitability (rs =0.289, p < 0.001), but its suitability scores were generally much lower than for flooded grassland. Quantitative data on Shoebill habitat suitability will be useful for future Shoebill population surveys, and will improve our ability to make informed decisions regarding its conservation.

AB - The Middle Iron Age in southern Africa has long been associated with the development of class distinction and state formation. However, most research focus has been on K2 and Mapungubwe in the Middle Limpopo Valley, the presumed first state capitals of the region. Mapela Hill is a site located outside the Middle Limpopo in south western Zimbabwe. Preliminary excavations at the summit of the hill by Peter Garlake in 1968 has resulted in archaeologists drawing contrasting conclusions about the position of the site in the development of complexity in the region. The problem is that we do not have sufficient evidence to support nor deny these theories. As a result of excavations from the foot of the hill to the hill summit, this study has used a combination of theories and analyses in order to classify the material cultural objects recovered at Mapela Hill. Ceramic studies have been used to identify the cultural groups which occupied the site, and tight radiocarbon dates were established, giving insight to the chronology of the site. The results showed that Mapela Hill was occupied by the same groups as at Mapungubwe Hill, contains vast revetment stone walling, successions of thick solid dhaka hut floors and an abundance of traded glass beads; attributes which collectively signify state formation in the region. The radiocarbon dates revealed that the site was occupied before, during and after the abandonment of Mapungubwe Hill. These results call for more research at relatively unknown sites in the region as a progression towards new frameworks for the development of state formation in the Shashe Limpopo confluence

AB - Using a historical materialist model of the rural-urban dialectic, this study is an analysis of the rural-urban articulation in Palestine c. 1200-1020 B.C.E., with particular reference to the aetiology of the conflict between the Israelite tribes and the Canaanites and Philistines. The model of the rural-urban dialectic which is developed in this thesis, posits that the relations between rural societies and urban societies in the ancient Near East were essentially antagonistic. Urban centers were sites of consumption rather than production. They were parasitic upon their rural hinterlands, extracting the produce of the village peasantry by means of enforced tributary relations. This extortion of the surplus product generated the conflict between the inhabitants of the rural areas and the city-dwellers. The resistance to such oppression by the peasantry engendered the class struggle in the ancient Near East, which took the form of conflict between the tribute exacting class, located in the cities, and the agrarian peasant class, located in the villages. The major thesis of this study is that the relations between the Israelite tribes and the Canaanites and Philistines can best be explained in terms of the rural-urban dialectic, which means that the conflict between the Israelite tribes and their urban neighbours was a manifestation of the antagonistic relations between rural and urban societies in the ancient Near East. The Canaanite and the Philistine societies were urban societies which existed as such by virtue of their ability to maintain tribute-extracting relations with the peasantry of their rural hinterlands. The Israelites, a tribal peasant society, were subject to this form of oppression to the extent to which they came under the orbit of Canaanite or Philistine power. The aetiology of the sustained conflict which pre-monarchic Israel experienced with the Canaanites and the Philistines lay in the relations of production imposed on them - relations which belong to the economic base of society - rather than in the realm of the superstructure, which includes the religious, political and ethnic aspects of a society. This conflict was expressed in religious, political and even ethnic terms, but had its source in the economic relations that existed between rural and urban societies in the ancient Near East.

AB - To date there is little data on conservative management of penetrating renal trauma. The aim of this study was to review the management and outcome of a large patient cohort presenting with penetrating renal trauma to a tertiary referral centre in South Africa. All patients presenting with penetrating abdominal trauma and haematuria admitted to the Trauma Centre at Groote Schuur Hospital over a 19-month period was prospectively evaluated. Patients demographics, mechanism of injury, microscopic versus macroscopic haematuria, grade of injury, management decision (non-operative, laparotomy for other reasons without renal exploration or true renal surgery with Gerotas fascia opened), nonsurgical success rate, complications, hospital stay, transfusion requirements and nephrectomy rate were analysed.

Background
There is a marked paucity of data concerning AKI in Sub-Saharan Africa, where there is a substantial burden of trauma and HIV.
Methods
Prospective data was collected on all patients admitted to a multi-disciplinary ICU in South Africa during 2017. Development of AKI (before or during ICU admission) was recorded and renal recovery 90 days after ICU discharge was determined.
Results
Of 849 admissions, the mean age was 42.5 years and mean SAPS 3 score was 48.1. Comorbidities included hypertension (30.5%), HIV (32.6%), diabetes (13.3%), CKD (7.8%) and active tuberculosis (6.2%). The most common reason for admission was trauma (26%). AKI developed in 497 (58.5%). Male gender, illness severity, length of stay, vasopressor drugs and sepsis were independently associated with AKI. AKI was associated with a higher in-hospital mortality rate of 31.8% vs 7.23% in those without AKI. Age, active tuberculosis, higher SAPS 3 score, mechanical ventilation, vasopressor support and sepsis were associated with an increased adjusted odds ratio for death. HIV was not independently associated with AKI or hospital mortality. CKD developed in 14 of 110 (12.7%) patients with stage 3 AKI; none were dialysis-dependent.
Conclusions
In this large prospective multidisciplinary ICU cohort of younger patients, AKI was common, often associated with trauma in addition to traditional risk factors and was associated with good functional renal recovery at 90 days in most survivors. Although the HIV prevalence was high and associated with higher mortality, this was related to the severity of illness and not to HIV status per se.

Of 849 admissions, the mean age was 42.5 years and mean SAPS 3 score was 48.1. Comorbidities included hypertension (30.5%), HIV (32.6%), diabetes (13.3%), CKD (7.8%) and active tuberculosis (6.2%). The most common reason for admission was trauma (26%). AKI developed in 497 (58.5%). Male gender, illness severity, length of stay, vasopressor drugs and sepsis were independently associated with AKI. AKI was associated with a higher in-hospital mortality rate of 31.8% vs 7.23% in those without AKI. Age, active tuberculosis, higher SAPS 3 score, mechanical ventilation, vasopressor support and sepsis were associated with an increased adjusted odds ratio for death. HIV was not independently associated with AKI or hospital mortality. CKD developed in 14 of 110 (12.7%) patients with stage 3 AKI; none were dialysis-dependent.
Conclusions
In this large prospective multidisciplinary ICU cohort of younger patients, AKI was common, often associated with trauma in addition to traditional risk factors and was associated with good functional renal recovery at 90 days in most survivors. Although the HIV prevalence was high and associated with higher mortality, this was related to the severity of illness and not to HIV status per se.

AB - This thesis is focused on architectural theories and design concepts which will add to the discourse of the what learning environments should or could be in the 21st century. It is based on the idea that spaces for learning need to be more “alive and that architecture can stimulate positive social interaction between people. The current public education system and its related standards, requirements and policies, with regards to physical learning spaces, does not address the present needs of children as it ought to. Many schools in South Africa are not built and designed to function as sustainable buildings and they often do not cater for the economic, environmental or social needs of current and future learners, teachers and community members.

AB - Job satisfaction is an essential factor for all employers and the benefits of a satisfied workforce have been proven. Understanding what the key factors that promote job satisfaction and how this differs amongst different age groups and years in a position is the purpose of this research study. Exploring the association between job satisfaction, performance and retention was a further goal of this study. This qualitative study was conducted with an exploratory and descriptive research design and adopted purposive sampling of seventeen officials employed in the City of Cape Town's Department of Social Development and Early Childhood Development. All participants were interviewed individually using a semi-structured interview schedule and the data gathered was presented along with direct quotes from these interviews. The research study found that financial remuneration and benefits, management, organisation culture, nature of work, emotional exhaustion, intrinsic satisfaction and development were key factors to the participants in terms of their job satisfaction. Interestingly, those factors considered basic or lower order, while important do not provide satisfaction, but can cause dissatisfaction if deficits are perceived. Satisfaction is found in those factors considered higher order or motivators and herein the participants felt there was room for improvement. Several distinctions were found between when considering the influence of these factors amongst both age and tenure amongst the participants. Furthermore, associations between retention and job satisfaction were not as evident as those found been job satisfaction and productivity. Key recommendations made for the Department of Social Development and Early Childhood Development centred on clarity on job descriptions and the nature of work and a reassessment of training and development. Finally, the mental health of the officials needs to be viewed as a priority, with considerations around organisation culture, management and communication.

AB - In the 2004 chapter on the Administration of Justice, we took the unusual step of criticising Juta, the publisher of the Annual Survey (at 823-6). We did so because we considered that Juta had behaved improperly in publishing a judgment critical of Jeremy Gauntlett SC but refusing his request to record that the Cape Bar Council had exonerated him of improper conduct. The details of the saga are fully recorded in last year's contribution and need not be repeated. As the publisher of the Annual Survey, Juta asserted a right to respond to the criticism levelled at it (2004 Annual Survey 845). Indeed, it appropriated an entire printed page to do so. Regrettably, we believe that Juta has compounded its error and that its comments cannot be allowed to stand unchallenged. In essence, Juta makes three points. First, the judgment on leave to appeal was reported because it 'contradicted a previous assumption that a dissenting judgment in the court a quo meant that leave to appeal would be granted as a matter of course' (ibid). Second, the South African Law Reports contains only such editorial comment as may be necessary to elucidate the published judgments. Third, '[i]t is not incumbent upon the publishers of law reports to annotate the reports in order to vindicate any of the persons who from time to time draw adverse comment from presiding judges' (ibid). None of these arguments withstand scrutiny.

AB - OBJECTIVE: We present the first report from the South African Register of Assisted Reproductive Techniques. METHODS: All assisted reproductive technology (ART) centres in South Africa were invited to join the register. Participant centres voluntarily submitted information from 2009 on the number of ART cycles, embryo transfers, clinical pregnancies, age of female partners or egg donors, and use of fertilisation techniques. Data were anonymised, pooled and analysed. RESULTS: The 12 participating units conducted a total of 4 512 oocyte aspirations and 3 872 embryo transfers in 2009, resulting in 1 303 clinical pregnancies. The clinical pregnancy rate (CPR) per aspiration and per embryo transfer was 28.9% and 33.6%, respectively. Fertilisation was achieved by intracytoplasmic sperm injection in two-thirds of cycles. In most cycles, 1 - 2 embryos or blastocysts were transferred. Female age was inversely related to pregnancy rate. CONCLUSION: The register achieved a high rate of participation. The reported number of ART cycles covers approximately 6% of the estimated ART demand in South Africa. The achieved CPRs compare favourably with those reported for other countries.

AB - The research study investigated the roles and challenges of DFIs in stimulating economic growth in an emerging market using DBSA and IDC, South Africa as a case study. The research study used a convergent mixed method research in understanding various intricacies surrounding challenges faced by the DFIs, by combining primary data obtained through a propulsive sampling of executive managers, senior managers and heads of divisions in a sample size of seven respondents for the qualitative analysis and quantitative secondary data obtained from annual reports and annual financial statements of both DBSA and IDC spanning five years. Moreover, the research study identified the role of DFIs in national economic policy formation and challenges hindering DFIs from meeting their mandates using qualitative analytical method of discourse and narrative analysis. Development banks across the globe play a sacrosanct role in stimulating economic development and economic growth in their respective jurisdictions. South Africa has various DFIs involved in different sectors of the economy. The country has seen minimal economic growth in recent years, and this is evidenced by the GDP growth rate, inequality and high unemployment rate. The research study findings revealed that the level of South African DFIs contribution to the total GDP value of the country is incredibly low when benchmarked against other emerging markets DFIs contribution to their countries’ GDP. The study also found that there is less participation on the side of the DFIs in policy-formulation. Moreover, the research findings further discovered that some of the targets entrenched in the economic policy frameworks guiding these institutions are impossible to achieve, let alone realise, rendering some of the targets as nothing but sheer chimera. The failure of other major state-owned entities places added responsibilities on these DFIs thus causing an overlap in their policy mandates. DFIs are faced with a conundrum of extending long term financing whilst remaining financially sustainable in the long run. Unlike many state-owned development banks from around the world, South African DFIs lack development capital from the government. While South African DFIs are active, well run and profitable, regrettably however their investments have not translated into meaningful economic development and this research study investigates why.

AB - Background The anthropomometry of the “ideal” breast is well described, but changes that occur with enlarged breasts are not. The aim of this study was to assess the prevalence of nipple asymmetry in the horizontal plane and changes in the inframammary fold (IMF) in patients presenting with macromastia (defined as excessive development of the mammary gland by Merriam-Webster dictionary). Methods One hundred patients (200 breasts) presenting to the Plastic Surgery Clinic for bilateral breast reduction were enrolled in this study. Patient's characteristics captured for this study included age, body mass index (BMI), and breast anthropometric measurements, such as suprasternal notch to nipple, nipple to IMF, IMF projected to cubital fossa, midhumeral point, and nipple measurement from meridian. Basic univariate statistical analysis were performed to evaluate the impact of nipple asymmetry. Results The average age was 37 years (SD 12 years), and the median BMI was 33 (IQR 28-37). More patients presented with nipple asymmetry, of whom 45% were classified as lateral to meridian, 19% were classified as medial to the meridian, and 36% were classified as central to the meridian. Patients with lateral asymmetry and medial asymmetry has a significantly higher BMI (median BMI 35) compared with patients with central positioning (median 30). Increasing breast size was positively associated with nipple asymmetry, whereas BMI (R = - 0.30, P =0.003) and macromastia correlated negatively with IMF position (R= - 0.38), P= 0.0001). Conclusion In macromastia, nipple displacement from breast meridian, especially lateral displacement, is common and is aggravated by an increase in BMI. The IMF also descends, and this is also common in patients with a raised BMI. These changes have clinical implications.

AB - This article provides a general background to this special focus section of the journal on ‘racial interaction and isolation in everyday life’. It reviews both the geographic literature on segregation and the psychological literature on the contact hypothesis, and calls for more research on how, when and why racial isolation manifests at a microecological level; that is, the level at which individuals actually encounter one another in situations of bodily co-presence. Some conceptual and methodological implications of this extension of the segregation literature are described. The social psychological signifi cance of the racial organisation of such ordinary activities as eating in cafeterias, relaxing on beaches and occupying public seating are also explored. The focus of the argument is that everyday boundary processes may maintain the salience of racial categories, embody racial attitudes and regulate the possibility of intimate contact.

AB - The notion of trust has great significance to an economy. Trust is known to be associated with efficient judicial systems, improved government functioning with lower corruption, and better financial outcomes (Johnson and Mislin, 2011). However, many researchers have argued that risk attitudes may confound the measurement of trust because trusting decisions involve outcomes that have only some probability of occurring. This study therefore seeks to question whether risk attitudes predict trusting decisions in the Berg, Dickhaut and McCabe (1995) Investment Game amongst students at the University of Cape Town in 2016. The statistical method adopted is maximum likelihood estimation which accounts for subject errors in decision making. This study finds that having additional information on the past behaviour of trustees does not affect the trusting behaviour of trustors. In addition, the presence of a human trustee, versus a computer, is found to significantly influence behaviour and decisions made by trustors in the trust game. It is also found that subjects are, on average, risk averse with 62% of subjects exhibiting high levels of risk aversion, and females being more risk averse than males. Subjects were also found to subjectively distort probabilities, where subjects would overweight low probabilities and underweight moderate to high probabilities. Expected Utility models and Rank-Dependent Utility models show that risk and trust are statistically significantly related and that the reasons for trusting one's partner may have arisen out of an inner need to simply trust that person. In addition, risk preferences were able to predict trusting decisions in the environment of risk and the environment of trust. Risk and trust therefore go hand-in-hand and it can be argued that trusting decisions are perceived as decisions involving risk. This study therefore finds that trusting decisions are in fact confounded by risk attitudes, so that a subject may be seen as trusting when actually they are just risk-seeking, or seen as non-trusting when they are just simply risk averse.

AB - This study explored the role of family on the career development of Xhosa-speaking graduates in South Africa. There are multiple environmental and individual influences on career development. However, this study focused specifically on family. The Xhosa culture, like other African cultures, endorses cultural values of deference and strong familial connections with extended family. Data from fourteen semi-structured in-depth interviews were analysed using thematic analysis. The key themes that emerged were (1) cultural beliefs, (2) social support and (3) the notion of black tax. The findings suggested that there is a strong relation between a family's cultural beliefs, family responsibilities and the perceived social support on graduate's career development. The understanding of ‘western' career aspirations with familial cultural expectations and support in forming a coherent self-concept could be considered a significant challenge in the career development of these Xhosa graduates. The findings supported the familial influences on graduates' career development and contributed new insights on how family influence is perceived and maintained from an intersectional perspective. The implications for career development in diverse contexts are offered.

AB - Southern Africa is endowed with lucrative mineral resources such as diamonds, gold, copper, coal, platinum, and uranium. is rich endowment can be a major asset in the quest for inclusive and sustainable development, yet mining in Southern Africa has often been criticised as an enclave sector that at best contributes little to economic development and at worst does substantial social and environmental harm. To avoid such pitfalls emerging international consensus emphasises the importance of good mineral governance. is involves the adoption and implementation of regulatory frameworks that promote deeper linkages between the mining sector and the broader economy, and that protect people and the environment from the potentially harmful consequences of mineral extraction. This pilot study provides a barometer of mineral governance in ten Southern African countries: Botswana, Democratic Republic of the Congo (DRC), Lesotho, Madagascar, Malawi, Namibia, South Africa, Swaziland, Zambia, and Zimbabwe. The barometer takes stock of mining regulations in place at the end of 2015, the extent to which they are implemented, and features of supporting institutions. It is based on the observation that while regulations impose obligations on mining companies, in doing so they directly impose obligations on the state to monitor and enforce compliance, and they also indirectly impose obligations for citizens and civil society to hold the state and mining companies accountable. The barometer includes indicators of mineral governance across four main issue-areas: national economic and fiscal linkages; community impact; labour, and the environment, with artisanal and small-scale mining (ASM) treated as a special topic. The barometer also includes indicators of state capacity and state accountability with respect to mineral governance.
Specialist researchers collected the data used to calculate the indicators in each country using a standardised research instrument. The in-country researchers collaborated in developing and re ning the instrument during two workshops. An important feature of the data set is that it consists of objective descriptions of patterns of regulation and implementation and of institutional arrangements, not on subjective value judgements. Researchers compiled information from publicly available, although not always easily accessible sources, to capture not only whether a particular regulation exists in a country, for example, but also whether the state has recently detected or penalised any company for failing to comply with regulations. Key findings can be summarised on three levels: the prevalence of regulations, the extent of monitoring and enforcement, and the importance of accountability. The prevalence of regulations varies substantially across countries but is generally high, with five of the ten countries having more than two-thirds of the regulations we looked for. The extent of monitoring and enforcement is considerably lower, with only patchy publicly-available evidence of states detecting and punishing non-compliance by mining companies. Accountability mechanisms that provide pluralistic fora for public participation emerge as the best predictors of monitoring and enforcement. Stated differently, government officials are less likely to overlook breaches by mining companies when the citizens and civil society are keeping track. The findings are also helpful in identifying gaps in what we call “regulatory presence” – a composite of regulations, monitoring, and enforcement. Regulatory presence is lower for economic/ scal linkages and community impact than it is for labour and environmental regulations. One interpretation is that labour and environmental regulations often apply by default across many sectors, while regulations about linkages and community impact are more specific to mineral extraction. A complementary interpretation is that civil society is often better organised around labour and environmental issues, while the affected constituencies in the other issue-areas are more likely to be sectorally fragmented (economic/fiscal linkages) or geographically isolated (community impact). National mineral governance scores differ in ways that in part reflect the size and importance of a country’s mining sector, but notable exceptions also emerge. The top four countries are well-known mining economies (South Africa, Zimbabwe, Botswana, and Zambia), however the scores of two other well-established mining economies (the DRC and Namibia) are noticeably lower (the DRC with many regulations but weak implementation, and Namibia with few regulations but a better record of implementing them). Lesotho and Swaziland, which have small mining sectors, had the lowest scores; however, the scores of the emerging mining economies of Madagascar and Malawi are noticeably higher, with Madagascar having the greatest regulatory presence on community impact and ASM, and Malawi scoring particularly well on environmental policies. The barometer provides an empirical baseline for describing mineral governance in the ten Southern African countries in the pilot study. Further research could extend this baseline to other countries and to the petroleum sector to facilitate a broader comparative and statistical analysis. The finding that accountability mechanisms are crucial suggests that further research is likely to more directly probe patterns of contestation across a range of key stakeholders from mining companies and the state to labour unions and civil society organisations.

Southern Africa is endowed with lucrative mineral resources such as diamonds, gold, copper, coal, platinum, and uranium. is rich endowment can be a major asset in the quest for inclusive and sustainable development, yet mining in Southern Africa has often been criticised as an enclave sector that at best contributes little to economic development and at worst does substantial social and environmental harm. To avoid such pitfalls emerging international consensus emphasises the importance of good mineral governance. is involves the adoption and implementation of regulatory frameworks that promote deeper linkages between the mining sector and the broader economy, and that protect people and the environment from the potentially harmful consequences of mineral extraction. This pilot study provides a barometer of mineral governance in ten Southern African countries: Botswana, Democratic Republic of the Congo (DRC), Lesotho, Madagascar, Malawi, Namibia, South Africa, Swaziland, Zambia, and Zimbabwe. The barometer takes stock of mining regulations in place at the end of 2015, the extent to which they are implemented, and features of supporting institutions. It is based on the observation that while regulations impose obligations on mining companies, in doing so they directly impose obligations on the state to monitor and enforce compliance, and they also indirectly impose obligations for citizens and civil society to hold the state and mining companies accountable. The barometer includes indicators of mineral governance across four main issue-areas: national economic and fiscal linkages; community impact; labour, and the environment, with artisanal and small-scale mining (ASM) treated as a special topic. The barometer also includes indicators of state capacity and state accountability with respect to mineral governance.
Specialist researchers collected the data used to calculate the indicators in each country using a standardised research instrument. The in-country researchers collaborated in developing and re ning the instrument during two workshops. An important feature of the data set is that it consists of objective descriptions of patterns of regulation and implementation and of institutional arrangements, not on subjective value judgements. Researchers compiled information from publicly available, although not always easily accessible sources, to capture not only whether a particular regulation exists in a country, for example, but also whether the state has recently detected or penalised any company for failing to comply with regulations. Key findings can be summarised on three levels: the prevalence of regulations, the extent of monitoring and enforcement, and the importance of accountability. The prevalence of regulations varies substantially across countries but is generally high, with five of the ten countries having more than two-thirds of the regulations we looked for. The extent of monitoring and enforcement is considerably lower, with only patchy publicly-available evidence of states detecting and punishing non-compliance by mining companies. Accountability mechanisms that provide pluralistic fora for public participation emerge as the best predictors of monitoring and enforcement. Stated differently, government officials are less likely to overlook breaches by mining companies when the citizens and civil society are keeping track. The findings are also helpful in identifying gaps in what we call “regulatory presence” – a composite of regulations, monitoring, and enforcement. Regulatory presence is lower for economic/ scal linkages and community impact than it is for labour and environmental regulations.

AB - In order to take account of the radical change in South Africa's international and continental environment, I have divided this thesis under two headings; policy towards colonial Africa (broadly, the period 1910 - 1959) and secondly, policy towards independent Africa (1960 - ). The division is by no means an absolute one. South Africa first began to feel the pressures of decolonization soon after the end of the Second World War. These took a variety of forms; for example, India's attacks on South Africa's racial policy and the United Nations' refusal to countenance the incorporation of South West Africa into the Union. They were echoed internally by growing militancy on the part of the African National Congress in the 1950's. Similarly after 1960, by which time most of the countries of Africa had achieved independence, the remnants of colonialism remained important to South African foreign policy. Firstly, the continuing existence of the Portuguese empire has carried the colonial order into the 1970's. Secondly, the former colonial powers have continued to exercise considerable influence on their ex-colonies. In particular, France's neo-colonial hold on many of her former colonies has assumed special importance in the context of South African initiatives towards francophone Africa.

AB - The prevention of mother-to-child transmission (PMTCT) programme in the Western Cape is said to have achieved 100% coverage.1 This implies that all pregnant women who attend an antenatal health care facility in the public sector are offered voluntary counselling and testing (VCT). Uptake varies but has been reported to be as high as 90% in the Guguletu district.1 Currently, women who test HIV-positive qualify for the nevirapine-based PMTCT programme. Transmission rates below 10% have been achieved in some health districts (Médecins sans Frontières — unpublished research). Mothers of several perinatally infected infants recently diagnosed in our institution have indicated that they tested HIV-negative during their pregnancy. In some cases we have verified their statements with clinical and laboratory documentation. There is a need to determine the frequency of this phenonomen. Pregnant women are encouraged to book at their nearest antenatal clinic before 5 months’ gestation, although this frequently does not occur. We are concerned about women who do book early and test HIV-negative. Some may be in the ‘window period’ of the infection or become infected from a sexual partner during the latter stages of pregnancy. At present, there is no provision within the PMTCT programme for repeat HIV testing during pregnancy. Some women may, therefore, be denied the benefits of prevention measures including counselling on infant feeding options.

AB - The hypothesis that increases in spawning frequency for and more viable eggs from larger hake lead to their making a disproportionately large contribution to recruitment is critically examined. The high steepness (h) estimated for stock-recruitment relationships for other than short-lived fish species worldwide, together with high h estimates from assessments for the South African hake populations, are at variance with this hypothesis, and suggest that the effect postulated is more than compensated by other densitydependent effects operative over the egg-to-recruit stage. This conclusion is supported by the relative insensitivity of OMP robustness test performance statistics to variations in underlying resource dynamics to incorporate this effect. Furthermore, even if larger hake off South Africa had been effectively protected from trawling in refugia, their numbers would have fallen as a result of the effects of fishing on younger animals; however no substantial decrease in recruitment is evident in assessments. While these counter-arguments do not exclude the possibility that recruitment is notably influenced by such effects (perhaps under more complex stock structure hypotheses), models fitted to data which demonstrate such behaviour would need to be developed before the hypothesis might be accorded any priority for attention in further research planning.

AB - We present deep H I imaging of the nearby spiral galaxy NGC 4414, taken as part of the Westerbork HALOGAS (Hydrogen Accretion in LOcal GAlaxieS) survey. The observations show that NGC 4414 can be characterized by a regularly rotating inner H I disk, and a more disturbed outer disk. Modeling of the kinematics shows that the outer disk is best described by a U-shaped warp. Deep optical imaging also reveals the presence of a low surface brightness stellar shell, indicating a minor interaction with a dwarf galaxy at some stage in the past. Modeling of the inner disk suggests that about 4 percent of the inner H I is in the form of extra-planar gas. Because of the disturbed nature of the outer disk, this number is difficult to constrain for the galaxy as a whole. These new, deep observations of NGC 4414 presented here show that even apparently undisturbed galaxies are interacting with their environment.

AB - Background: Trauma contributes significantly to the burden of disease and mortality throughout the world, but particularly in developing countries. In Tanzania, there is an enormous research gap on trauma; the limited data available reflects realities in cities and areas with moderately- to highly-resourced treatment centers. Our aim was to provide a description of the injury epidemiology across all of Tanzania. Our data will serve as a basis for future larger studies. Methods: This is a subgroup analysis of a cross-sectional, prospective study of the clinical epidemiology of patients presenting at all public district and regional hospitals in Tanzania. The study was conducted between May 2012 and December 2012. A team of emergency doctors used a purpose-designed data collection sheet to gather the demographic and clinical information of all patients presenting during the day-site visit to each hospital. Descriptive statistics, including means, standard deviations, medians, and ranges are reported. Results: A total of 5227 patients were seen in 24-h period in 105 (100% response rate) district (or designated district) and regional hospitals in mainland Tanzania. Of these patients, 508 (9.7%) presented with trauma-related complaints. Among patients with trauma-related complaints, 286 (56.3%) were male, and the overall median age of 30 (interquartile range of 22–35) years. Road traffic crash was the most common mechanism of injury, accounting for 227 (44.7%) complaints. Open wounds and bone fractures were the two most frequent diagnoses, with a combined 300 (59%) cases. Most of the patients - 325 (64%) - were discharged, 11 (2.2%) went to operating theatres and 4 (0.8%) of patients died while receiving care at the acute intake areas. Conclusions: Trauma-related complaints constitute a substantial burden among patients seeking care in acute intake areas of hospitals across Tanzania. There is a need to develop, implement and study systems that can support the improvement of trauma care and optimize outcomes of trauma patients.

Background: Trauma contributes significantly to the burden of disease and mortality throughout the world, but particularly in developing countries. In Tanzania, there is an enormous research gap on trauma; the limited data available reflects realities in cities and areas with moderately- to highly-resourced treatment centers. Our aim was to provide a description of the injury epidemiology across all of Tanzania. Our data will serve as a basis for future larger studies. Methods: This is a subgroup analysis of a cross-sectional, prospective study of the clinical epidemiology of patients presenting at all public district and regional hospitals in Tanzania. The study was conducted between May 2012 and December 2012. A team of emergency doctors used a purpose-designed data collection sheet to gather the demographic and clinical information of all patients presenting during the day-site visit to each hospital. Descriptive statistics, including means, standard deviations, medians, and ranges are reported. Results: A total of 5227 patients were seen in 24-h period in 105 (100% response rate) district (or designated district) and regional hospitals in mainland Tanzania. Of these patients, 508 (9.7%) presented with trauma-related complaints. Among patients with trauma-related complaints, 286 (56.3%) were male, and the overall median age of 30 (interquartile range of 22–35) years. Road traffic crash was the most common mechanism of injury, accounting for 227 (44.7%) complaints. Open wounds and bone fractures were the two most frequent diagnoses, with a combined 300 (59%) cases. Most of the patients - 325 (64%) - were discharged, 11 (2.2%) went to operating theatres and 4 (0.8%) of patients died while receiving care at the acute intake areas. Conclusions: Trauma-related complaints constitute a substantial burden among patients seeking care in acute intake areas of hospitals across Tanzania. There is a need to develop, implement and study systems that can support the improvement of trauma care and optimize outcomes of trauma patients.

AB - The differing susceptibility of individuals to the toxic effects of chronic lead exposure has never been fully understood. As the major intake of lead in the human is from food and beverages, any variation between individuals of the quantity of lead absorbed from the gut, and of the distribution and excretion of this lead, may account for the differences in individual susceptibility. The food and beverages themselves may have an influence, and to investigate their effects on absorption, distribution and excretion of lead, experiments were performed on normal subjects using a short-lived radionuclide of lead, ²⁰³Pb, and instruments generally available in Nuclear Medicine. Lead absorption between different individuals showed a wide variation when ²⁰³Pb was taken as a single dose between meals. The effect of fasting was to increase absorption and reduce the variation. This suggested that food with the lead in the gut was mainly responsible for the variation in lead absorption between individuals. This was confirmed when ²⁰³Pb was mixed into a control meal and eaten by fasted subjects. Lead absorption was again low and variable. In contrast, ²⁰³Pb taken in distilled water was avidly absorbed with little variation between subjects. The absorption of lead in water could be appreciably more than lead in food amongst the general population. Minerals were found to be mainly responsible for affecting absorption when one subject ingested ²⁰³Pb in control meals from which one dietary constituent at a time was omitted. The effect of minerals in reducing absorption of lead was greatest when they were ingested in distilled water. Lead in water with a low mineral content, such as 'soft' water, could be a hazard to population groups living in 'soft' water areas. There were also indications from these experiments that dietary constituents may affect the distribution and excretion of lead. Calcium and phosphorous were found to reduce the absorption of ²⁰³Pb to approximately the same level as that produced by the total minerals. Calcium reduced absorption more than phosphorous when these minerals were ingested separately with ²⁰³Pb. Paired kinetic experiments showed that calcium and phosphorous ingested at the same time as ²⁰³Pb affected its distribution in the body but not its rate of excretion. Using the data from the kinetic experiments, a compartmental model was developed which adequately described the kinetics of orally ingested ²⁰³Pb. The model suggested that calcium is mainly responsible for reducing absorption of lead from the gut, but that the effect of phosphorous is to increase soft tissue levels of lead at the expense of red cell lead. As susceptibility is related to soft tissue levels of lead, this suggests that the 'protective' effect of calcium in the gut is reduced. This could not be confirmed, however, as the kinetic data were insufficient for the model to distinguish the tissues particularly vulnerable to lead toxicity in the soft tissue compartment. It was concluded that the calcium and phosphorous in the diet could influence susceptibility to lead toxicity through changes in the absorption of food and water lead and in the distribution of lead in the body. The results suggest that the prophylactic effect of calcium on lead absorption should be recognised and applied in this time of increased environmental levels of lead.

AB - This paper charts the development of the two institutions most central to the nature of representative democracy in South Africa: the electoral system and the National Assembly.2 It reviews how developments since 1994 have shaped the institutional context in which political parties operate and compete for power. The paper first considers how the National Assembly has developed over the past ten years, reviewing the performance of parliament and its role in the consolidation of democracy. The second part of the paper focuses on the electoral system, reviewing the debate around electoral reform and discussing changes that have been introduced since 1999. In the conclusion, we suggest what the implications of these institutional developments are for the future of representative democracy in South Africa.

AB - The Response of mobile intertidal invertebrates to subsistence harvesting in Northern KwaZulu Natal was investigated. Spatial scale comparisons were made between as well as within harvested and non-harvested locations. The difference in three population variables was investigated: i) abundance of species groups. ii) size structure of each organism and iii) community structure of mobile organisms. Abundance analysis revealed no significant difference between harvested and no harvested regimes for most species' groups, excepting Snails and Chitons. Snails were more abundant und chitons less abundant at harvested sites. A significant difference.... between locations was however noted, for all species groups, suggesting that variation in abundance within is more prominent than between harvesting regimes. Size stmcturc analysis revealed significantly larger sizes for most spec1cs at non harvested locations, with only Morula gm1111/u111 and Scutellastm exusw showing u significantly larger size structure at non-harvested locations. Community structure analysis revealed no clear distinction between or wi1hin harvested locations. A decrease in size structure with no co1Tespondi11g density effect may be a function of the preference of harvesters for larger individuals, thereby favouringjuveaile populations. The possibility also exists that density effects have been masked due to the use of size instead of biomass data. Converting to size data to biomass, using wet mass versus size regressions, may be a more appropriate analysis method. The observed differences in community structure between as well ru; within loi:-ations indicates that the intertidal communities are inl1erintly hcterogenous in this area. ln order 10 determine the irnpacr of exploitation. spatial scale comparisons between harvesting regimes thus ideall y need to be conducted to each location. [n this study there was also a lack of representative control sites, us unharvested locatio11s are impacted by fisherman and tourists. A possible strategy would be to demarcate "110-go" areas in harvested and non-harvested areas, to serve as both controls and provide broodi11g stocks for adjacent ledges. It is however recommended that more research emphasis be placed on U1e user in evaluating the effects ofhurmtn tmpact on intertidal resource.

AB - This paper focuses on the work of South African black lesbian photographer Zanele Muholi and raises the question of how experience that is deemed unspeakable can enter representation. If we always read images through ‘‘codes of connotation,’’ through what Roland Barthes terms the ‘‘studium’’ of our knowing, how is it possible to overturn ways of seeing that render lesbian subjectivity invisible?2 And if lesbian subjectivity is made visible through suspending the structures of recognition, what are the political implications of occupying such an ‘‘outlaw’’ position? How does being beyond recognition open or close the field of political possibility? The paper makes two theoretical claims: one, that Barthes’ influential concept of the ‘‘punctum’’ can be understood as a mode of queer reading, and two, that Muholi’s work constructs an archive that insists on the specificity of lesbian lives and loss through a complex strategy of ‘‘passing.’’ My reading of Muholi’s portraits that constitute her ‘‘Faces and Phases’’ series explores how her photographs work with the ambiguities of ‘‘passing’’—passing away, passing between states of gendered being, and passing through the prohibitions against making lesbian experience visible and mourning lesbian loss. In this way, the paper argues that Muholi’s most recent body of work ‘‘queers’’ both the conventions of memorial photography and her own earlier representations of lesbian subjectivity.

AB - The diagnosis of pulmonary tuberculosis (PTB) in children is challenging. Difficulties in acquiring suitable specimens, pauci-bacillary load, and limitations of current diagnostic methods often make microbiological confirmation difficult. Chest imaging provides an additional diagnostic modality that is frequently used in clinical practice. Chest imaging can also provide insight into treatment response and identify development of disease complications. Despite widespread use, chest radiographs are usually non-specific and have high inter- and intra-observer variability. Other diagnostic imaging modalities such as ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) can provide additional information to substantiate diagnosis. In this review, we discuss the radiological features of PTB in each modality, highlighting the advantages and limitations of each. We also address newer imaging technologies and potential use.

The diagnosis of pulmonary tuberculosis (PTB) in children is challenging. Difficulties in acquiring suitable specimens, pauci-bacillary load, and limitations of current diagnostic methods often make microbiological confirmation difficult. Chest imaging provides an additional diagnostic modality that is frequently used in clinical practice. Chest imaging can also provide insight into treatment response and identify development of disease complications. Despite widespread use, chest radiographs are usually non-specific and have high inter- and intra-observer variability. Other diagnostic imaging modalities such as ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) can provide additional information to substantiate diagnosis. In this review, we discuss the radiological features of PTB in each modality, highlighting the advantages and limitations of each. We also address newer imaging technologies and potential use.

AB - The wettability of mineral surfaces plays an important role in the flotation process. A wettable mineral is hydrophilic while a non-wettable mineral is hydrophobic. In the flotation process, sufficiently hydrophobic particles are collected by rising air bubbles and they report to the concentrate. On the other hand, hydrophilic particles do not attach to the air bubbles and they report to the tailings. Some of the conventional methods used to characterise mineral surface wettability include contact angle, inverse gas chromatography (iGC), time of flight secondary ion mass spectrometry (ToF-SIMS) and induction time measurements. The measurement of contact angles on flat, smooth and ideal surfaces is relatively simple, straight forward and well-described, but the measurement of powder contact angles is not so straight forward. The iGC technique is a gas phase technique while ToF-SIMS exposes the particles under high vacuum compared to an aqueous environment in real flotation systems. This thesis has investigated the use of the enthalpy of immersion as an indicator of the wettability of mineral surfaces. The enthalpy of immersion is the heat change arising from the replacement of the solid-gas interface with the solid-liquid interface when a solid surface is immersed in a liquid. Although immersion calorimetry has been established as a reliable means of determining the wettability of solid surfaces, it has found only limited applications in flotation research where wettability of mineral ores is a key variable. In this study, precision solution calorimetry was employed to measure the enthalpies of immersion of different minerals in water. The Washburn method and a microflotation system were used to measure the corresponding powder contact angles and the flotation responses of the same minerals respectively. Two mineral systems were investigated in this study, viz: different pure minerals in their natural form as well as collector-coated sulphide minerals. Furthermore, to assess whether the enthalpy of immersion is able to differentiate between the amounts of minerals of different wettabilities in a mineral mixture, a synthetic ore comprising of different proportions of a sulphide mineral (realgar) and a silicate gangue mineral(albite) was also investigated. The surface energetics of different minerals and the synthetic ore were also characterised by measuring the enthalpies of immersion in different probe liquids and applying the van Oss-Chaudhury-Good (VOCG) model. The VOCG model is reported to give consistent results in terms of surface energetics of surfaces. It has been found that the enthalpy of immersion technique was capable of distinguishing differences in the wettabilities of different minerals and these differences were explained in terms of the solid state properties of the minerals. The enthalpy of immersion method was also able to assess the changes in the surface chemical properties of the galena and realgar surfaces resulting from collector adsorption. The magnitude of the enthalpy of immersion was inversely related to the surface coverage of potassium amyl xanthate on both galena and realgar. The enthalpy of immersion measurements correlated well with powder contact angle measurements, but, most importantly, the enthalpy of immersion measurements were found to be more reproducible and sensitive than the contact angle measurements. It has also been shown that the enthalpy of immersion is a more widely applicable measure of the hydrophobicity of mineral particles typical of those used in the flotation process as opposed to the contact angle. It is therefore concluded that the enthalpy of immersion is a superior indicator of the extent to which minerals are hydrophobic or hydrophilic either in their natural form or after treatment with a collector. Furthermore, it was found that there was a strong inverse relationship between the enthalpy of immersion of the minerals studied and their flotation response. The strong inverse relationship has potential to be used in pulp phase flotation models, although this was not the focus of this thesis. In addition, a value, termed the critical enthalpy of immersion (CEI), was observed above which no flotation occurred. The CEI was in the region of -200 mJ/m². At values less exothermic than the CEI, the flotation response was found to be inversely related to the enthalpy of immersion. At values more exothermic, viz. more negative, than the CEI, no flotation occurs. The significance of this finding is that for any mineral whose flotation behaviour is unknown, the measurement of the enthalpy of immersion appears to be able to predict the flotation response of the mineral. The variance in the inverse relationship between enthalpy of immersion and rate of flotation was reduced when the data was normalized with respect to particle density which was the only variable in the flotation studies in terms of particle-bubble encounter efficiency. These results have shown that the enthalpy of immersion is an excellent indicator of both the natural mineral hydrophobicity and of the extent to which collectors render a mineral hydrophobic. The relative strength of the acid-base sites was shown to depend on the mineral type. The surface energetics obtained in this study were consistent with the hydrophobichydrophilic nature of these minerals. The basic, polar components as well as the total surface energy decreased in the following order: silicates > metallic sulphide minerals and talc. It was observed that the higher the total surface energy, the lower the hydrophobicity of the mineral. The acid-base characteristics of the minerals, measured by solution calorimetry, can give a detailed insight into the surface energies of different mineral types and may be useful in optimising processing strategies. Using the surface energetics, two important parameters were calculated, viz: the interfacial free energy of interaction between mineral particles and bubbles immersed in water (∆Gpwb) as well as the work of adhesion for water (Wadh). Interestingly, and not surprisingly, the trends in both of these parameters coincided with the trend in the enthalpies of immersion of the different minerals in water. Critical values of ∆Gpwb and Wadh parameters in the region of 200 mJ/m² and 320 mJ/m² respectively were observed above which no flotation occurs. At values less than the critical values, both parameters were inversely related to the flotation response. The enthalpy of immersion was able to differentiate between the amounts of minerals of different wettabilities in a mineral mixture. The enthalpy of immersion became increasingly exothermic as the percentage of albite in the realgar-albite mixtures increased. The experimentally determined enthalpies of immersion in water were in excellent agreement with the weighted enthalpies of immersion for the realgar-albite mixtures. The weighted enthalpies of immersion of the synthetic ore were calculated based on the specific surface areas of both realgar and albite. Therefore, it is possible to calculate the enthalpy of immersion of a synthetic ore (mineral mixtures) from the knowledge of the proportion and the enthalpy of immersion in water of the individual minerals comprising the synthetic ore. The surface energetics of the synthetic ore showed that there is a relationship between the mass recovery and the calculated relative surface polarity, based on the individual polar and total surface energies. As the relative surface polarity increases, there is a significant decrease in the mass recovery after a relative surface polarity of about 0.4. Thus, the enthalpy of immersion has the potential to be used to predict the wettability and the floatability potential of mineral mixtures. It is proposed that this work should be extended to other mineral mixtures, with careful measurement and calculation of the surface energetics of these mixtures. Thus, this work presents an opportunity for further study to investigate the use of the enthalpy of immersion to characterise the wettability of real ores.

AB - The shift from apartheid to a constitutional democracy in South Africa, brought with it a plethora of questions concerning ideas of nationhood, citizenship, and organisational transformation. Integrally caught up in the revolution, the South Africa Police Service (SAPS) faces transformative challenges on scales far larger than most other organisations in the country. From being the strong arm of the oppressive elite, it has has to restructure and rearticulate its function while simultaneously attempting to maintain law and order. Like many other corporations and organisations, the SAPS has engaged in interventions aimed at aiding the fluidity of this process. This thesis is an analysis of one such intervention. It attempts to ascertain the extent to which members are changing as a result of particular diversity workshops conducted in a region of the Western Cape.

The objective, within the methodological genre of the hermeneutical circle, is to see a method emerge that is fundamentally balanced; in other words, a theological method that is able to engage with immediate context, wider history, current theologies and classical theologies. Holland and Henriot's notion of the hermeneutical circle - the pastoral circle - emerges as just such as appropriate methodology. There are some minor additions to the pastoral circle that in no way detract from its fundamental methodolgy. In fact, I would argue, they enhance the given methodology of the pastoral circle.

AB - South African oceanographers were engaged in collecting hydrographic and biological sea truth data in order to calibrate the CZCS measurements from the NIMBUS-7 satellite over the Benguela Upwelling region and along the east coast of South Africa during the period 1978 to 1981. A brief overview of the CZCS validation programme and its application to the South African marine environment is given, followed by an analysis of level-Til CZCS data obtained from NASA for the region 10° - 60°S, and 10° - 100°E. This area includes the Benguela Upwelling system on the continental shelf, and the Southern Ocean with the Subtropical Convergence zone south of Africa. High annual values (5mg m⁻³) of chlorophyll occurred in the Benguela shelf region, typical of other upwelling systems in the world ocean, and the data shows a strong interannual signal in the seven years of composited data from 1978-1985, with maxima in 1982. Two distinct regimes were found in the Benguela Upwelling system, the seasonal variations of pigment concentration in the northern and southern Benguela regions being out of phase. In the Southern Ocean, the values of chlorophyll were generally low (0.15mg m⁻³) with the strongest signal (1.5mg m⁻³) found at the southern border of the Agulhas retroflection region and its frontal boundary with the colder subantarctic water to the south. The high values of chlorophyll found in this region are ten times the typical open Southern Ocean values. There is a clear interannual signal in the CZCS data for this Subtropi£al Convergence region, which has a low value in 1979 rising to a maximum in 1981 and then decreasing to another low value in 1985. There appears to be no pronounced seasonal variation in the Subtropical Convergence data. Reasons for the strong signal in the surface chlorophyll concentrations at the front between the Agulhas Return Current and the Southern Ocean are discussed, and it is shown that the Agulhas Plateau sets up a topographic Rossby wave in the Agulhas Return Current, which can be clearly identified in the CZCS signal. The large expanse of the Subtropical Convergence region is found as able to sustain a standing stock of phytoplankton similar in magnitude to that on the Benguela shelf, for limited periods of time. A brief analysis of sea surface temperature versus chlorophyll concentration shows the relationship between the two parameters to take the form of an inverted parabola, having a temperature window within which maximum chlorophyll concentrations are found.

Reasons for the strong signal in the surface chlorophyll concentrations at the front between the Agulhas Return Current and the Southern Ocean are discussed, and it is shown that the Agulhas Plateau sets up a topographic Rossby wave in the Agulhas Return Current, which can be clearly identified in the CZCS signal. The large expanse of the Subtropical Convergence region is found as able to sustain a standing stock of phytoplankton similar in magnitude to that on the Benguela shelf, for limited periods of time. A brief analysis of sea surface temperature versus chlorophyll concentration shows the relationship between the two parameters to take the form of an inverted parabola, having a temperature window within which maximum chlorophyll concentrations are found.

AB - Urgent and effective conservation is needed to halt the declines of endangered African Penguins. A purse-seine fisheries closure zone was in place out to 20 km around Robben Island for three years. It provided an opportunity to investigate penguin foraging behaviour in relation to estimated local prey abundance and other factors without the confounding variable of local fishing. Penguins provisioning chicks were equipped with GPS temperature depth devices for a foraging trip. Dive data (N = 75) and GPS tracks (N = 78) were collected from 78 penguins. Of those, 14 penguins were at-sea within two days of a fine-scale hydro-acoustic pelagic fish survey. Diet sampling, breeding success and chick body condition monitoring took place in the colony. Nests were followed to outcome. Morphological indicators were developed for sex determination and body condition. Intrinsic factors, brood mass, prey abundance, wave height and direction were explored in respect to foraging behaviour. Kernel density analysis identified foraging areas, confirming consistent use of the closure area. Annual differences in foraging effort were explained by variation in local prey abundance. The time the penguins spent diving and the distance travelled from the colony were negatively related to local prey abundance. There was greater variation in foraging distance when prey abundance was lower. Foraging areas and dive behaviour were similar for the sexes. The survival of chicks in the foraging study did not differ from chicks monitored in the colony for breeding success (control chicks). The trips of penguins with nesting success (N = 44) were on average 4.5 km closer to the colony than the penguins that had nesting failure (N = 21). Chick body condition in the colony was positively related to the Anchovy (Engraulis encrasicolus) mass percentage in the diet and the local pelagic fish abundance; condition was predicted to vary by 245% over the range of local fish abundance observed during the study period (0.5 to 187 thousand tonnes). Identifying ways to avoid depletion of prey resources around penguin colonies is important for conservation of the species.

AB - This study explores the factors that affect the involvement of parents with their mentally handicapped children after the children have been admitted to Lentegeur Care and Rehabilitation Centre in Mitchells Plain, Cape Town. The study was motivated by the concern of the researcher regarding the lack of parent-child contact and the failure of attempts by social work staff to increase parental involvement. For the purposes of the study involvement is defined as visits and telephone calls by parents to the institution and their subjective description of their emotional closeness to their children. The literature review explores the effect the presence of a mentally handicapped child may have on family functioning and the circumstances that may cause the family to consider placing the child in an institution. Other studies concerned with parent-child involvement after institutionalization are reviewed.

AB - Attrition bias is a problem for users of panel data. Researchers need to know what socio-economic factors are associated with attrition, and whether this is of relevance for the kind of analysis they want to conduct. This paper discusses attrition bias in the 2000/2004 Khayelitsha panel study. It shows that women, shack-dwellers and people living in smaller households are more likely to attrit, but that the impact of these variables on the probability of attrition is relatively small. The implications for labour-market analysis are then explored using Mincerian earnings functions and a probit regression on whether respondents are wage-employed or not. The coefficients generated using a restricted sample of non-attritors do not differ significantly from those generated by the entire sample. This suggests that attrition bias in this particular data set is not a problem for this kind of labour market analysis.

AB - This comparative study investigates the media representation of YouTube-based news about the #MeToo campaign, feminism, and sexual harassment accounts in three BRICS nations: China, Russia and Brazil. The situation of women in the Global South was at the centre of discussions during the 2018 BRICS summit. While their security remains a persistent issue, officials declared that women should not feel unsafe while participating in economic activity. Although the bloc flagged gender disparities as a significant concern, media outlets perceive Russia, Brazil and China's responses to sexism and gender-based violence as inadequate. Various mechanisms also compromise activism for women's rights. This research focuses on the YouTube representation of conditions which gave rise to the campaign and the process of #MeToo in BRICS. This study considers the level of inclusion of women in economic activity, the procedures established for their safety as well as the extent of media freedom, including tools available for feminist advocacy. In addition to revealing gaps in depiction and proposing solutions for improved media framing, this research is significant because the role and repercussions of this viral campaign must be comprehended better in BRICS economies. Academics focused mainly on the impact of the movement in the West. However, the innovative feminist trend rapidly spread to non-western nations that are dominant emerging economies, showing the gravity of sexual harassment and gender disparities globally. Furthermore, the extent to which #MeToo had influenced localised iterations of anti-assault movements in these emerging countries suggests that the BRICS became sites where sexual abuse and gender inequalities unfold singularly in comparison to other nations. The study presents findings from primary research done on the BRICS, this online social movement #MeToo and related gender dynamics issues. After a presentation of the selected study design, the research provides results from a content analysis of thirty YouTube news reports (October 2017-March 2019).

AB - Africa is not unique in its need for basic bioinformatics training for individuals from a diverse range of academic backgrounds. However, particular logistical challenges in Africa, most notably access to bioinformatics expertise and internet stability, must be addressed in order to meet this need on the continent. H3ABioNet (www.h3abionet.org), the Pan African Bioinformatics Network for H3Africa, has therefore developed an innovative, free-of-charge “Introduction to Bioinformatics” course, taking these challenges into account as part of its educational efforts to provide on-site training and develop local expertise inside its network. A multiple-delivery–mode learning model was selected for this 3-month course in order to increase access to (mostly) African, expert bioinformatics trainers. The content of the course was developed to include a range of fundamental bioinformatics topics at the introductory level. For the first iteration of the course (2016), classrooms with a total of 364 enrolled participants were hosted at 20 institutions across 10 African countries. To ensure that classroom success did not depend on stable internet, trainers pre-recorded their lectures, and classrooms downloaded and watched these locally during biweekly contact sessions. The trainers were available via video conferencing to take questions during contact sessions, as well as via online “question and discussion” forums outside of contact session time. This learning model, developed for a resource-limited setting, could easily be adapted to other settings.

Africa is not unique in its need for basic bioinformatics training for individuals from a diverse range of academic backgrounds. However, particular logistical challenges in Africa, most notably access to bioinformatics expertise and internet stability, must be addressed in order to meet this need on the continent. H3ABioNet (www.h3abionet.org), the Pan African Bioinformatics Network for H3Africa, has therefore developed an innovative, free-of-charge “Introduction to Bioinformatics” course, taking these challenges into account as part of its educational efforts to provide on-site training and develop local expertise inside its network. A multiple-delivery–mode learning model was selected for this 3-month course in order to increase access to (mostly) African, expert bioinformatics trainers. The content of the course was developed to include a range of fundamental bioinformatics topics at the introductory level. For the first iteration of the course (2016), classrooms with a total of 364 enrolled participants were hosted at 20 institutions across 10 African countries. To ensure that classroom success did not depend on stable internet, trainers pre-recorded their lectures, and classrooms downloaded and watched these locally during biweekly contact sessions. The trainers were available via video conferencing to take questions during contact sessions, as well as via online “question and discussion” forums outside of contact session time. This learning model, developed for a resource-limited setting, could easily be adapted to other settings.

AB - The assessment conducted in this dissertation was shaped by the intended formulation of an Integrated Coastal Zone Management Plan (ICZMP), as proposed by the Danish Co-operation for Environment and Development. An ICZMP provides an integrated and holistic approach to planning, in which the various activities and resource demands that occur within the coastal belt and neighbouring regions are appropriately coordinated. The first phase of the formulation of this management plan entailed the compilation of a baseline report summarising the present state of the environment in the study area, with particular emphasis on the major issues which will require attention in an ICZMP. This study was undertaken by Masters students from the Department of Environmental and Geographical Science at the University of Cape Town. The study area is located within the coastal belt of Namibia's Erongo Region, and more specifically within the magisterial districts of Swakopmund and Walvis Bay (Map 3). This includes the National West Coast Tourist Recreation Area and a portion of the Namib Naukluft Park. The southern boundary extends to the Sandwich Harbour, while the northern boundary extends to the southern bank of the Ugab River. The eastern perimeter is that of the Swakopmund magisterial district, and includes the municipal areas of Walvis Bay, Henties Bay and Arandis, together with Rossing Mine and its immediate environment. The seaward boundary is defined by the three nautical mile limit from shore. The Baseline Report: Coastal Zone Management Plan for the Erongo Region, Namibia was submitted to DANCED in March 1996. The findings of the investigation, as recorded in the report, highlight a number of issues which require urgent attention in the ICZMP. One such issue concerns the rapid influx of migrants to the urban centres in the study area. Population is a determining factor which significantly influences the functioning of other key sectors within a given location. As such, an understanding of the ramifications of increased population numbers is imperative to the formulation of an ICZMP. The objective of this dissertation was, therefore, to identify the factors generating rapid migration to the study area, and to facilitate an assessment of the impacts of this phenomenon. Once identified and assessed, these impacts can be better managed within a holistic, integrated framework.

AB - During the past ten years the world demand for vitamin A has increased steadily. The increase is due partly to growing popularity of vitamin therapy and partly to the enormous rate at which vitamin A is being used in America for animal feeding. During the war years it has been used extensively for food fortification in England and Europe, and this will probably be continued for several years. It is very difficult to estimate the annual world consumption of vitamin A, but we know that in America 67 x 10¹² International Units (I. U.) were used in 1939. Approximately 60% of this quantity was used for animal feeding. We also know that in England the fortification of margarine is compulsory and that the diet of all school children is supplemented with vitamin A. The distribution of the world production of vitamin A was seriously disrupted by the war, when the Norwegian and Japanese productions were cut off from their normal destinations. Under these circumstances it is no wonder that the United States, Canada, South Africa, India and Australia made serious and successful attempts to produce fish liver oils, the main source of vitamin A. Argentina produced 25 x 10¹² U.S.P. units in 1945 and the United States 9 x 10¹³ U.S.P. units in the same year. The South African production increased from 2 x 10¹² I.U., valued at £80,000 in 1943, which year may be regarded as the birth of the South African industry, to 1 x l0¹³ I.U., valued at £400,000 in 1946-1947. There are four companies engaged in the production of fish liver oils in South Africa, and the success of this venture has probably provided the biggest impetus to our rapidly expanding fishing industry. This treatise deals with some aspects of the composition, characteristics, production, refining and storage of soupfin shark liver oil.

AB - This design dissertation follows a narrative process of research and design speculation. The report defines the subject of the project and is the first part of the dissertation. The subject can be divided into the two major themes of: historically defensive territory and voyeurism or peoples' desire for publicness. The project is initiated through this pairing of seemingly antithetical themes. The second part and final outcome is a building proposal. Its function has been formed through my engagement with themes. The resultant programme is a civic sports precinct at Trafalgar Park and Baths in Woodstock, Cape Town. I chose this site for it concealed a hidden narrative in the city. The ruin of an 18th century Dutch defence system in the park was a catalyst for the investigation. Creating a civic recreational space in this guarded public territory (both historically and at present) became the object of my project. The narrative of keeping-out emerges as a socio-historical reading of the site. The possibility of seeing-in between sites of activity and how this informs publicness became the first spatial informant for the design project for public space.

AB - The main objective of this project is to develop an adaptive relaying system that will protect the microgrid both in connected and isolated modes. Therefore the settings for the different relays will be observed for the two modes of operation. This will determine whether they are correctly coordinated in order to operate as an adaptive relaying system. A secondary but also important objective is to identify load management techniques through smart metering that could facilitate power system operation and in turn power system protection. To achieve the goal of this project the proposed relaying system will have to prove appropriate in all the test cases. Based on the results obtained in the simulations, conclusions about the relaying scheme were drawn. Based on cases where the scheme seemed inappropriate or could be improved, recommendations were made. The relaying scheme proposed in this project proved highly successful in detecting abnormalities and protecting the power system when necessary.

AB - This research investigates the representation of people in museums, focusing on the San, South Africa’s first nation. Using a multimodal social semiotic framework, it analyses three exhibitions of the San that were mounted over a period of a hundred years in a natural history museum from 1911 to the present. The research takes into consideration the socio-political background in which the exhibitions were designed, and examines how this manifests in the ways in which the San were represented. The analysis surfaces three dominant discourses, namely evolutionary, ecological as well as a discourse of transformation. These discourses are complex and always in dialogue with one another. The research entailed working with and analysing photographs and drawing on secondary texts of two exhibitions that are no longer open to the public, and analysing an existing exhibition. The data analysis was framed by the semiotic principles of recontextualisation as posited by Bezemer and Kress (2008): selection, social relations and arrangement. Selection refers to the choice of meaning materials for an exhibition. Arrangement refers to the decisions made in the display of the meaning materials (including layout, framing, and foregrounding), and social relations pertain to the social repositioning that takes place in the process of recontextualisation. The research showed how discourses shifted across time, but that dominant discourses such as an evolutionary discourse persisted through the ages and the various exhibitions. By analysing exhibitions of the San against the political backdrop of colonialism, apartheid and post-apartheid this research contributes to an understanding of colonial museums and their exhibitions. It provides suggestions to South African museum practitioners dealing with colonial collections on how to bring a decolonial perspective to exhibitions. The insights gained through this research may enable museum professionals to better understand meaning making and representation in museum display and to contribute to current debates on representation, including ways in which dominant discourses are reflected and refracted in museums. The dialogue between discourses and traces of discourse is of interest within the museum context as well as other contexts of transformation. The research shows that it is possible to map a re-imagining of museum display on the three principles of recontextualisation – selection, arrangement and social relations – in order to see what forms transformation in museum display could take.

AB - There is a long history of street trading restriction in South Africa, and the relocation of traders from key public spaces in Cape Town, in connection with renovation and construction for the 2010 FIFA World Cup, highlighted the contested nature of street trading in the Cape Town city centre. The Grand Parade, South Africa's oldest public space, sits adjacent to the city's major public transport hub, and plays a vital role in the daily lives of many city residents. Therefore, public space contestations, and the informal sector's importance in job creation and poverty reduction, necessitate an investigation into the impacts of the City of Cape Town's street trading management approach on the livelihood strategies of traders on the Parade. I review relevant literature on street trading management, and develop criteria for assessing the City of Cape Town's street trading management approach. These criteria are linked to Lefebvre's (1968) and Fainstein's (2010) concepts of 'the right to the city' and 'the just city' respectively. The main research question thus asks: What is the impact of the City of Cape Town's street trading management approach on the livelihood strategies of traders on the Grand Parade? The research uses the case study and discourse analysis methods to address this question. Data is collected through nonparticipant observation and individual semi-structured interview techniques. The focus is on capturing the views and experiences of traders on the Grand Parade. The research findings indicate that the City of Cape Town tends to adopt a more restrictive approach to managing traders on the Grand Parade, and that this has, effectively, a negative impact on trader livelihoods. This approach serves to produce informal arrangements, aggression and resistance on the part of traders. A disjuncture is found between the stated developmental approach of the City's Informal Trading Policy (informed by national developmental policies) and its practices. The combination of organisational restructuring processes, confused mandates as well as the low political and funding priority given to street trading management has meant that the complex of socio-economic factors and persistent management issues on the Parade, that require interdepartmental cooperation to address, continue to negatively impact trader livelihoods. I recommend that the City of Cape Town, in line with the aims contained in its Informal Trading Policy, and inspired by the 'eThekwini model', implement a more progressive street trading management approach that is based on participatory and area-based approaches. A dedicated focus on capacitating trader organisations through training initiatives is recommended, as well as changes to trading permit application processes and conditions. Lastly, specific recommendations are also made to better enable livelihood strategies of street traders on the Grand Parade.

The Grand Parade, South Africa's oldest public space, sits adjacent to the city's major public transport hub, and plays a vital role in the daily lives of many city residents. Therefore, public space contestations, and the informal sector's importance in job creation and poverty reduction, necessitate an investigation into the impacts of the City of Cape Town's street trading management approach on the livelihood strategies of traders on the Parade. I review relevant literature on street trading management, and develop criteria for assessing the City of Cape Town's street trading management approach. These criteria are linked to Lefebvre's (1968) and Fainstein's (2010) concepts of 'the right to the city' and 'the just city' respectively. The main research question thus asks: What is the impact of the City of Cape Town's street trading management approach on the livelihood strategies of traders on the Grand Parade? The research uses the case study and discourse analysis methods to address this question. Data is collected through nonparticipant observation and individual semi-structured interview techniques. The focus is on capturing the views and experiences of traders on the Grand Parade. The research findings indicate that the City of Cape Town tends to adopt a more restrictive approach to managing traders on the Grand Parade, and that this has, effectively, a negative impact on trader livelihoods. This approach serves to produce informal arrangements, aggression and resistance on the part of traders. A disjuncture is found between the stated developmental approach of the City's Informal Trading Policy (informed by national developmental policies) and its practices. The combination of organisational restructuring processes, confused mandates as well as the low political and funding priority given to street trading management has meant that the complex of socio-economic factors and persistent management issues on the Parade, that require interdepartmental cooperation to address, continue to negatively impact trader livelihoods. I recommend that the City of Cape Town, in line with the aims contained in its Informal Trading Policy, and inspired by the 'eThekwini model', implement a more progressive street trading management approach that is based on participatory and area-based approaches. A dedicated focus on capacitating trader organisations through training initiatives is recommended, as well as changes to trading permit application processes and conditions. Lastly, specific recommendations are also made to better enable livelihood strategies of street traders on the Grand Parade.

AB - Copper smelting residues from C. AD 1650 found at the Drierivier site near Rehoboth in central Namibia have 207Pb/206Pb isotope ratios that match a particular deposit at Swartmodder, but are markedly different from other known occurrences in the Rehoboth–Windhoek areas. For this reason, precise lead isotope determination is not necessary to source the ore, and raw peak height ratios obtained by inductively coupled plasma mass spectrometry are sufficient. This characteristic signature is present in all samples of malachite ore, slag, and copper prills collected on the site. Significantly, it is absent from a sample of local native copper, as well as from seven copper beads found elsewhere in central Namibia. This not only identifies the probable source of malachite ore but also provides a powerful tool for provenancing copper artefacts made at the Drierivier site, distinguishing them from those made elsewhere in the Namibian highlands.

AB - This study is the first of its kind undertaken at Groote Schuur Hospital. It is an attempt to provide a holistic profile of their elderly patients with a view to encouraging further, more specific research, and to provide information for use in the planning of efficient health care for the aged. The study was based on three premises: (i) there is an interrelationship between the ageing process and disease; (ii) a non-disease-specific approach which focusses on the functional status of elderly patients can be used as a predictor of health services consumption; and (iii) any study which promotes understanding of the dynamics of health care of the elderly must also take into account the ageing process and its effect on a particular population within a specific social context. The research spanned 52 weeks (1 March 1989 - 27 February 1990). A sample of nine patients per week was selected from the total population of patients aged 65 and over admitted to the Emergency Unit of Groote Schuur Hospital. Two adult female researchers, using structured questionnaires, constructed in English and comprising subtests, utilising indexes and scales, interviewed respondents and/or household members in their own homes. Data was also obtained from the hospital files. Although essentially descriptive by nature, use was made of groups in regard to variables such as "first admission" (admission to the Emergency Unit), and "readmission" (a previous overnight admission in the preceding year). Statistical analysis, where indicated, was by means of non-parametric tests.

AB - Concern’s that the world’s energy supply will not be able to keep pace with rising energy demands, have surfaced periodically for much of the petrochemical industry’s nearly 150 year history, but each time the industry has responded with technological advances and innovations to satisfy the global energy needs. Future advances will most likely include the enhanced recovery of conventional oil, the production of extra-heavy oil / tar sands and the utilization of alternative energy production technologies (technologies other than crude oil refining). The Fischer-Tropsch Synthesis (FTS) discovered in 1923 by Fischer and Tropsch, is one of these alternative fuel production technologies and can briefly be defined as the means used to convert synthesis gas containing hydrogen and carbon monoxide over a group VIII metal catalyst to hydrocarbon products and water. Given the vast product spectrum possible for the FTS (paraffins, olefins, alcohols, carbonyls, acids and aromatics), a great deal of controversy still exists as to the chemical identity of the monomeric building block and the propagation of the hydrocarbon chain on the catalyst surface [van Dijk., 2001]. Several mechanisms have been published with the four most popular (alkyl, alkenyl, enol and CO-insertion), recently reviewed by Claeys and van Steen (2004). It must however, be appreciated that given the complexity of the FT reaction it is generally accepted that more than one mechanism may operate on the catalyst surface at any one time. Furthermore, process parameters such as temperature, total pressure, partial pressure, hydrogen to carbon monoxide ratio, space velocity and residence time all have an influence on the FT product selectivity. Because of this it becomes exceptionally complicated to determine the effects of just one parameter while taking the effects of the additional parameters into account.

AB - The cheetah (Acinonyx jubatus) is by far the most manoeuvrable and agile terrestrial animal. Little is known, in terms of biomechanics, about how it achieves these incredible feats of manoeuvrability. The transient motions of the cheetah all involve rapid flicking of its tail and flexing of its spine. The aim of the research was to develop tools (hardware and software) that can be used to gain a better understanding of the cheetah tail and spine by capturing its motion. A mechanical rig was used to simulate the tail and spine motion. This insight may inspire and aid in the design of bio-inspired robotic platforms. A previous assumption was that the tail is heavy and acts as a counter balance or rudder, yet this was never tested. Contrary to this assumption, necropsy results determined that the tail was in fact light with a relatively low inertia value. Fur from the tail was used in wind tunnel experiments to determine the drag coefficient of a cheetah tail. No researchers have actively sought to track the motion of a cheetah's spine and tail during rapid manoeuvres via placing multiple sensors on a cheetah. This requires the development of a 3D dynamic model of the spine and tail to accurately study the motion of the cheetah. A wireless sensor network was built and three different filters and state estimation algorithms were designed and validated with a mechanical rig and camera system. The sensor network consists of three sensors on the tail (base, middle and tip) as well as a hypothetical collar sensor (GPS and WiFi were not implemented).

AB - There has been an allergy clinic at Red Cross Children’s Hospital from the day that the doors opened 50 years ago. This may not appear surprising given the prevalence of allergic conditions in children, but even today few major teaching hospitals in South Africa have paediatric allergy clinics – this despite the recent International Study of Asthma and Allergies in Children (ISAAC) which ranked South Africa twelfth in prevalence out of the 56 countries surveyed.

AB - Background: Dedicated and motivated health workers (HWs) play a major role in delivering efficient and effective health services that improve patients’ experience of health care. Growing interest in HW motivation has led to a global focus on pay for performance strategies, but less attention has been paid to nurturing intrinsic motivation. Workplace trust relationships involve fair treatment and respectful interactions between individuals. Such relationships enable cooperation among HWs and their colleagues, supervisors, managers and patients and may act as a source of intrinsic motivation. This paper presents findings from a qualitative systematic review of empirical studies providing evidence on HW motivation, to consider what these studies suggest about the possible influence of workplace trust relationships over motivation.
Methods: Five electronic databases were searched for articles reporting research findings about HW motivation for various cadres published in the 10-year period 2003 to 2013 and with available full free text in the English language. Data extraction involved consideration of the links between trust relationships and motivation, by identifying how studies directly or indirectly mention and discuss relevant factors.
Results: Twenty-three articles from low- and middle-income countries and eight from high-income countries that met predetermined quality and inclusion criteria were appraised and subjected to thematic synthesis. Workplace trust relationships with colleagues, supervisors and managers, employing organisation and patients directly and indirectly influence HW motivation. Motivational factors identified as linked to trust include respect; recognition, appreciation and rewards; supervision; teamwork; management support; autonomy; communication, feedback and openness; and staff shortages and resource inadequacy.
Conclusion: To the authors’ knowledge, this is the first systematic review on trust and motivation in the health sector. Evidence indicates that workplace trust relationships encourage social interactions and cooperation among HWs, have impact on the intrinsic motivation of HWs and have consequences for retention, performance and quality of care. Human resource management and organisational practices are critical in sustaining workplace trust and HW motivation. Research and assessment of the levels of motivation and factors that encourage workplace trust relationships should include how trust and motivation interact and operate for retention, performance and quality of care.

AB - In this article, we consider how we can use the text Deconstructing developmental psychology to read child migration to South Africa. We argue that this text offers a useful analytic method for critical reflections on child migrants in South Africa for several reasons. First, it allows us to shift the focus away from children as a taken for granted object of analysis to a focus on the historical and contextual emergence of developmental psychology as a discipline and, more importantly for this paper, the nature of the child that has been produced through this disciplinary establishment. Second, it offers critical reflections on the exclusions created by this dominant discourse of the child which we elaborate. In particular, we make an argument for why a text that reflects primarily on the Anglo/US developmental psychology should be useful in the contemporary South African context. As an illustration, we give examples from ethnographic research that the authors conducted in two borderlands – the South Africa/ Mozambican border and the South Africa/Lesotho border. We use this example to show first how the migrant child that is imagined in South African law is a fantasy of the western child imagined in international child rights regimes. We contrast this production of the child with the everyday experiences of child migrants at the border. In particular, the assumption that the family is the natural place for children and the state is only involved with children whose families neglect these responsibilities is rendered nonsensical for children living in borderlands where the state shapes their otherwise
everyday practices and activities.

AB - In Tanzania, palliative care is relatively new, and faces the common challenges of access to services, crucial medications, and education. Since 2004, an initiative within the health system of the Evangelical Lutheran Church in Tanzania (ELCT) began to promote and develop palliative care, using as a model the Selian Hospice and Palliative Care Programme. The hospitals which are the sites for team development and service delivery are widely scattered throughout rural Tanzania. Access to oral morphine was only a dream, as it is for much of the rural population of the world. In 2007, a program called CHAT (Continuum of care for people living with HIV/AIDS in Tanzania), funded by the U.S. government, allowed the up-scaling of these palliative care programs, resulting in 13 strong and mature teams by 2011, though still lacking oral morphine. Part of the monitoring and quality assurance of the program has been use of a tool developed by APCA: the APCA African Palliative Outcome Scale (POS). Hundreds of people living with cancer and HIV were subjected to the questions of the tool, which was always sent on to the core supervising team for assessment and feedback. Tramadol was the strongest analgesic available to the teams throughout the study time. 145 APCA African POS results on cancer patients were assessed, looking at differences in pain scores (0 to 5 scale) over time as well as assessing the other domains of care (psychological, spiritual, social, and family). 11 Palliative care nurses were also interviewed, asked to reflect on specific cases from their experience with both good and bad pain control. 5 of the nurses came from Selian, with access to oral morphine, while 6 of them came from the CHAT hospitals. Significant improvement in pain scores over 4 weeks was noted (3.83 to 2.31, p < 0.0001). All other domains assessed in the POS also improved significantly. Nurse interviews revealed an emphasis on the holistic approach and a strong preference for having access to oral morphine. In this rural Tanzanian environment, effective palliative care services – including pain control - were delivered even in the absence of oral morphine. Such services can become a strong advocacy at the government level for achieving breakthroughs in palliative care, including access to oral morphine.

AB - Host and pathogen ecology are often closely linked, with evolutionary processes often leading to the development of host specificity traits in some pathogens. Host specificity may range from ‘generalist’, where pathogens infect any available competent host; to ‘specialist’, where pathogens repeatedly infect specific host species or families. Avian malaria ecology in the region remains largely unexplored, despite the presence of vulnerable endemic avian species. We analysed the expression of host specificity in avian haemosporidia, by applying a previously developed host specificity index to lineages isolated from wetland passerines in the Western Cape, South Africa. Parasite lineages were isolated using PCR and identified when possible using matching lineages deposited in GenBank and in MalAvi. Parasitic clades were constructed from phylogenetic trees consisting of Plasmodium and Haemoproteus lineages. Isolated lineages matched some strains of Plasmodium relictum , P. elongatum , Haemoproteus sylvae and H. lanii . Plasmodium lineages infected a wide range of hosts from several avian families in a generalist pattern of infection. Plasmodium spp. also exhibited an infection trend according to host abundance rather than host species. By contrast, Haemoproteus lineages were typically restricted to one or two host species or families, and displayed higher host fidelity than Plasmodium spp. The findings confirm that a range of host specificity traits are exhibited by avian haemosporidia in the region. The traits show the potential to not only impact infection prevalence within specific host species, but also to affect patterns of infection at the community level.

AB - The larger population of South African learners do not learn effectively and struggle with low academic achievements currently. This can be attributed to various factors such as frequent changes in the curriculum, underqualified educators, ineffective teaching methods and barriers to learning existing in classrooms today. Learners need extra support, including cognitive support, but in reality the heavy workload of educators may prevent them from giving learners the needed support. If support is given, it is minimal or not effective enough. Computer technologies may afford both educators and learners such opportunities when used as a cognitive tool in activities that provide the needed support. This research is concerned with the use of computer technology as a cognitive tool to activate learners' cognitive processes, thus enhancing learning, based on Brain Based Education principles. The objective is to lay the foundation in using computer technologies as cognitive tools in educators' teaching practice and instructional design to make teaching and learning more effective, interactive, real world based, giving meaning to what is learnt and to enhance understanding.

Le Roux ZJ. An application of brain-based education principles with ICT as a cognitive tool: a case study of grade 6 decimal instruction at Sunlands Primary School. [Thesis].

The larger population of South African learners do not learn effectively and struggle with low academic achievements currently. This can be attributed to various factors such as frequent changes in the curriculum, underqualified educators, ineffective teaching methods and barriers to learning existing in classrooms today. Learners need extra support, including cognitive support, but in reality the heavy workload of educators may prevent them from giving learners the needed support. If support is given, it is minimal or not effective enough. Computer technologies may afford both educators and learners such opportunities when used as a cognitive tool in activities that provide the needed support. This research is concerned with the use of computer technology as a cognitive tool to activate learners' cognitive processes, thus enhancing learning, based on Brain Based Education principles. The objective is to lay the foundation in using computer technologies as cognitive tools in educators' teaching practice and instructional design to make teaching and learning more effective, interactive, real world based, giving meaning to what is learnt and to enhance understanding.

AB - Background: Adolescents’ sexual and reproductive healthcare (SRH) needs have been prioritized globally, and they have the rights to access and utilize SRH services for their needs. However, adolescents under-utilize SRH services, especially in sub-Saharan Africa. Many factors play a role in the under-utilization of SRH services by adolescents, such as the attitude and behaviour of healthcare workers. The aim of this study therefore, was to explore and gain an in-depth understanding of healthcare workers’ beliefs, motivations and behaviours affecting adequate provision of these services to adolescents in South Africa. Methods: Twenty-four healthcare workers in public SRH services in Cape Town, South Africa participated in this qualitative study through focus group discussions. To fulfill the aims of this study, nine focus group discussions were conducted among the SRH nurses. Results: SRH nurses indicated that they are experiencing challenges with the concept and practice of termination of pregnancy. They explained that this practice contradicted their opposing beliefs and values. Some nurses felt that they had insufficient SRH skills, which hinder their provision of adequate SRH services to adolescents, while others described constraints within the health system such as not enough time to provide the necessary care. They also explained having limited access to schools where they can provide SRH education and pregnancy prevention services in the surrounding area. Conclusions: Nurses are faced with numerous challenges when providing SRH services to adolescents. Providing the nurses with training programmes that emphasize value clarification may help them to separate their personal beliefs and norms from the workplace practice. This may help them to focus on the needs of the adolescent in a way that is beneficial to them. At the health systems level, issues such as clinic operating hours need to be structured such that the time pressure and constraints upon the nurse is relieved.

AB - Proton exchange membrane fuel cell (PEMFC) has been reported as clean and efficient energy technology from conversion of H₂. However, one of the main challenges remains the storage and transport of hydrogen. The promising alternative is to produce H₂ on site by a reformer using a H₂-dense liquid as a fuel, a technology known as fuel processing. Methanol is an attractive source of H₂ compared to other fuels as it presents several advantages, i.e. it is obtained sulphur-free, has a high H to C ratio and therefore produces a H₂-rich reformate, can be reformed at low temperatures (200 - 300°C) and is a liquid at ambient conditions so that it can be easily handled. Typically, Cu-based catalysts are used for steam reforming of methanol due to their high activity (i.e. H₂ production) and high selectivity towards CO₂. As CO poisons anodic catalyst of PEMFC, high selectivity towards CO₂ is crucial so as to eliminate or at least minimize CO removal load downstream a fuel processor. However, Cubased catalysts are thermally unstable and suffer deactivation due to sintering at high temperatures (> 250°C). Moreover, Cu-based catalysts are pyrophoric and therefore difficult to handle. Recent studies show that PdZn catalysts are very promising as they exhibit comparable activity and selectivity to Cu-based ones. Furthermore, PdZn catalysts are thermally stable in the typically methanol steam reforming temperature range (200 - 300°C). Most literature attributes high CO₂ selectivity of PdZn catalysts to formation of PdZn alloy. It is generally agreed that PdZn alloy is formed when PdZn catalysts are reduced in H₂ at high temperatures (> 250°C). In this work, a Pd/ZnO catalyst aimed at 2.5 wt% Pd was successfully prepared via incipient wetness impregnation and the duplicate preparation of the catalyst was successful. Both impregnation catalysts were confirmed by ICP-OES to contain similar weight Pd loadings i.e. 2.8 and 2.7 wt%, respectively. The actual Pd loading (ICP-OES) was slightly higher than the target loading (2.5 wt%) due to Pd content of Pd salt underestimated during catalyst preparation. Furthermore, crystallite size distribution, i.e. PdO crystallites on ZnO support, was similar (i.e. 6.7 ± 2.4 nm and 6.3 ± 1.9 nm) for both impregnation catalysts.

AB - Two separate assays for prizidilol have been developed. One relies on separation by high performance liquid chromatography, and the other on separation by thin layer chromatography. Both of these methods have several advantages over the existing assay developed by JC Pearce for Smith Kline and French Ltd. (SK & F). Firstly, both methods utilize pepsin to digest plasma protein since it is known that precipitation with trichloroacetic acid of the protein leads to losses by binding at different rates of prizidilol and of the internal standard. The SK & F assay might therefore be less sensitive and precise than necessary. Secondly, use of the complexing reagent, quinolin-3-al, leads to greater sensitivity of detection than the reagent, anisaldehyde, previously employed. The minimum level of quantitation of the developed assays are approximately 30 μg/1 by HPLC and 15 μg/1 by TLC, as against 50 μg/1 by the earlier HPLC method originating from SK & F laboratories. Finally, the TLC method is much quicker to perform than the previous assay.

AB - The South African wine industry is the eighth largest producer of wine in the world. Despite its progress since the 1990s, the industry has come under increased competition from other wine producers. The wine industry grew rapidly from 1994 until 2005 when it started to face major challenges that led to only a quarter of wine farmers producing at financially sustainable levels, reductions in the number of grape farmers and the area of vineyard under cultivation, and job cuts, low pay, and low prices. The most immediate constraints to the competitiveness of the wine industry are global competition, inadequate innovation, and volatile input costs of production. Therefore, this thesis contributes to the debate on these issues by (i) examining South Africa's wine competitiveness against other Southern Hemisphere New World (SHNW) producers; and (ii) investigating wine consumers' perceptions of and willingness to pay for product innovation by the South African wine industry; and (iii) investigating the impact of energy price volatility on South African wine prices. The main research questions/contributions are addressed in Chapters 3, 4, 5 and 6 as follows: Chapter 3 investigates the competitiveness of South African wines against rivals in the SHNW, and the determinants of their performance in the global wine market. The aim is to identify priority areas to focus on to enhance South Africa's competitiveness and sustain the industry. Global competition, especially among the SHNW producers, has been cited as one of the causes of the poor performance by the South African wine industry (Esterhuizen and Van Rooyen, 2006; Van Rooyen et al., 2011; Van Rooyen and Boonzaaier, 2018). The export market is critical for South African wines considering that half of its annual production is sold abroad (SAWIS, 2020). Also that exports attract higher earnings for the industry. Therefore, comparing the degree of South African wine competitiveness with other SHNW producers and investigating factors influencing specialisation will help identify priority areas to focus on to enhance South Africa's competitiveness and sustain the industry. The 1990 to 2018 panel data from Global Wine Markets is used for the analysis. Trade specialisation and their determinants are determined through (i) the computation of the Revealed Comparative Advantage, (ii) estimation of the Galtonian regression model and (iii) estimation of the panel regression model. The findings reveal that all countries migrated to higher price points with variable degrees of success. As a result, South African wines were relatively less competitive than their rivals. The study reveals the relative position of the South African wine industry and draws inferences on priority areas for enhancing competitiveness. Chapter 4 investigates wine consumers' perceptions of and willingness to pay for product innovation by the South African wine industry. The aim is to elicit information on whether consumers are ready to pay for wines made with natural preservatives (Rooibos & Honeybush), organic production, and a higher quality score. Determining whether consumers choose such wines is crucial as it would reveal whether wine players can exploit this source of avenue to save the struggling industry. It contributes to knowledge by being the first study to estimate the premium price for not having added SO2 in wine by substituting the conventional wine preservative with Rooibos and honeybush — a natural preservatives. The Discrete Choice Experiment (DCE) approach elicited willingness to pay for the innovative alternative. Consumers' preferences for organic wine, wine quality, and cost were also examined. Results from the mixed logit model indicate that consumers are willing to pay additionally R60.40 per bottle of wine with natural preservatives, while they are ready to pay R19.45 more for organic wine and R1.55 for each point on quality score. Chapter 5 investigates the robustness of the empirical estimates obtained in chapter 4. Identified as a potential methodological issue in the DCE literature, the chapter contributes to knowledge by examining the influence of ‘price framing' on empirical estimates in environmental valuations. The tests are performed using data from a choice experiment on preferences for natural preservatives in wine. The same respondents completed a nearly identical DCE survey, one with a real price and another with a percentage price change. 611 respondents completed the survey, and a panel mixed logit model was used for the analysis. Results demonstrate that ‘price framing' significantly influenced respondents Willingness To Pay for wine attributes. The study sheds light on the establishment of guidelines for developing valid cost attributes in DCE. Chapter 6 investigates whether energy price volatility influences South African wine prices. The aim is to establish the extent to which energy price volatility affects wine prices. The implication of the findings is that a formula of dependence and risk between energy and wine markets could be established and used to protect the wine industry from spillovers and foster wine market stability. The study contributes to knowledge by thoroughly examining the volatility behaviours of energy (fuel and electricity) and wine prices. Using a Multivariate Generalized Autoregressive Conditional Heteroscedasticity (MGARCH) model, the chapter estimates own- and cross-volatility spillovers and persistence between the South African energy and wine markets using monthly Consumer Price Index data from 2002 to 2018. Results from the analysis indicate positive and significant volatility effects, with a substantial spillover from the energy market to the wine market. The results also indicate that only fuel and wine prices move together in the long run.

AB - Background Diabetes has been reported as being the tenth leading cause of death in South Africa, and can affect a person's livelihood, productivity and physical ability. In particular, gestational diabetes mellitus (GDM) affects 7-10% of pregnancies worldwide and greatly increases the risk of developing Type II diabetes after pregnancy, particularly if the patient has a high Body Mass Index. Research suggests that accurate education and proper management regarding diabetes can have a positive impact on the quality of patient life, as well as the country's healthcare system. One such disease management platform exists as mHealth, which is the acronym for mobile health, and is best described to be the use of mobile communication for health services and information. This report intends to Method The information for this report was gathered by means of a combination of Internet research, alreadyexisting knowledge of the subject, textbooks, journal articles, and thoughtful direction from the project supervisor. The research consisted of three studies: a systematic review, prototype design, and a user survey. The systematic review collected and analysed existing literature related to the knowledge and impact of mHealth among pregnant women with or at risk of GDM in underserved communities. The use of mHealth was analysed by focusing on its impact on outcomes related to glycaemic control, pregnancy and delivery, and behaviour and knowledge. This information was then used to develop a suitable mobile health platform targeted at a specific user: a pregnant woman. Design methods were used to identify the most effective solution, and a prototype was built using the online software Proto.io. User feedback on the produced prototype was received through an interview questionnaire, which was hosted by the online survey system SurveyMonkey. Results By paying close attention to parameters limited to under-served communities, the systematic review included four articles relevant to the scope of the research. Through the outcome analysis, the review revealed that two of the more common reasons for the development of GDM is a newly-pregnant woman being unaware of the risk, as well as lack of immediate access to available information on how to self-manage her pregnancy. It was identified that patient follow-up played a major role in helping them maintain weight and glucose goals, which is one of the driving factors behind the design of the intervention. Based on the requirements and specifications of the solution, a mobile application was chosen to be developed, in order to be able to develop a solution with the capability to meet a list of functions and features identified through the collected literature and user-based design. From the 33 respondents to the survey, it was discovered that majority (81.82%) of the respondents expressed competence in the use of mobile technology and had access to the internet and a smartphone. Most respondents (60.61%) specified that they preferred receiving knowledge in a ‘hands-on' capacity. Majority of the findings lined up with the collected literature as it was determined that the respondents believed having access to key medical and health information has a positive effect on the health outcomes of both mother and baby. Conclusions The investigation concluded that providing women with access to information and self-management platforms generally results in an increase in positive health outcomes for both women and their babies, during pregnancy and later in life. From the systematic review results, mobile health has a significant and positive impact on a patient's quality of life, as well as the healthcare industry. The results indicated technology can improve patient knowledge, understanding and management of GDM, though more research and controlled trials are required to support this deduction.

AB - This thesis contains the results and discussion of an exploratory investigation into the application of Crossflow Microfiltration (CFMF) for solid/liquid separation in biological wastewater treatment systems. The principal objective of the study was to assess the influence of CFMF on the performance of identified biological wastewater treatment systems. It was not the objective to optimise filtration performance. A literature review indicated that the crossflow mode of filtration has been widely accepted as a unit operation in the fermentation industry. The filtration mode is now being applied not only for solid/liquid separation but also for separations on a molecular and ionic level. Very few applications of crossflow filtration in the context of biological wastewater treatment solid/liquid separation are reported in the literature. The reasons for this limited experience would appear to be the scale involved and the perceived high costs; separations in the fermentation industry are usually conducted at relatively small scale (laboratory or pilot-scale) and involve high-value products, justifying high capital and operating costs. Also, the high level of separation performance attained is perhaps not necessary for many wastewater treatment applications. No doubt these reservations are largely valid. However, these arguments cannot be applied equally to all filtration methods and wastewater treatment schemes. For example, the costs of microfiltration are substantially less than ultrafiltration or reverse osmosis, and in certain cases effluents with extremely low suspended solids contents may be required. In the light of these observations an investigation of CFMF for solid/liquid separation in biological wastewater treatment systems appears justified. Two biological treatment systems were selected for study: the Upflow Anaerobic Sludge Bed (UASB) reactor and the Activated Sludge system. The envisaged benefits accruing from the application of CFMF were different in each case.

AB - BACKGROUND: Combination therapy is one of the most effective tools for limiting the emergence of drug resistance in pathogens. Despite the widespread adoption of combination therapy across diseases, drug resistance rates continue to rise, leading to failing treatment regimens. The mechanisms underlying treatment failure are well studied, but the processes governing successful combination therapy are poorly understood. We address this question by studying the population dynamics of Mycobacterium tuberculosis within tuberculosis patients undergoing treatment with different combinations of antibiotics. RESULTS: By combining very deep whole genome sequencing (~1000-fold genome-wide coverage) with sequential sputum sampling, we were able to detect transient genetic diversity driven by the apparently continuous turnover of minor alleles, which could serve as the source of drug-resistant bacteria. However, we report that treatment efficacy has a clear impact on the population dynamics: sufficient drug pressure bears a clear signature of purifying selection leading to apparent genetic stability. In contrast, M. tuberculosis populations subject to less drug pressure show markedly different dynamics, including cases of acquisition of additional drug resistance. CONCLUSIONS: Our findings show that for a pathogen like M. tuberculosis, which is well adapted to the human host, purifying selection constrains the evolutionary trajectory to resistance in effectively treated individuals. Nonetheless, we also report a continuous turnover of minor variants, which could give rise to the emergence of drug resistance in cases of drug pressure weakening. Monitoring bacterial population dynamics could therefore provide an informative metric for assessing the efficacy of novel drug combinations.

AB - The main aim of this thesis is to investigate the potential benefits of increasing resolution in regional climate models in the simulation of climate variability and change over East Africa. This study is based on two high resolution regional climate simulations with a horizontal resolution of 50km and 10km, respectively. These represent present day climate and a projection of future climate change over East Africa. The regional climate model (RCM) used here is HIRHAM5, which is driven by the global circulation model (ECHAM5). Downscaled ECHAM5 output is used to drive the 50km HIRHAM5 simulation for the period 1950-2100, and output from this simulation is used to drive the 10km simulation for three time slices: 1980-1999, representative for present-day climate and two time slices for near future (2046-2065) and far future (2080- 2099), respectively. HIRHAM5 is evaluated with respect to the observed mean climatologies of rainfall, surface temperature and surface winds over East Africa, and representations of the observed annual cycles and inter-annual variability of rainfall and surface temperature. This study utilizes reanalysis and observational datasets: a hindcast of HIRHAM5 forced with ERA Interim, as well as two observation datasets for temperature and rainfall. Since reanalyses aim to make "best use" of all available observations by making a physically consistent representation continuous in time and space, and since there is a paucity of observations over many parts of Africa, the ERAI reanalysis is also used as a best estimate for model evaluation. Additionally, for evaluation of the bimodal nature of East Africa's rainfall, especially over Tanzania, three stations run by the Tanzania Meteorological Agency were used. The model data used in th is evaluation ranges from 1980 to 2006 iv HIRHAM5 demonstrates reasonable skill in the reproduction of observed patterns of mean climatology of rainfall, surface temperature and winds over East Africa. Moreover, the patterns of annual cycles of rainfall and surface temperature in the bimodal nature of East Africa are well represented. Furthermore, the model showed reasonable skill in the representation of the inter- annual variability and ENSO signals as suggested by the observation. Despite these strengths, HIRHAM5 shows some shortcomings. One weakness of the model is the simulation of the magnitude of a given variable over a specific region. For example, HIRHAM5 driven by ERAI underestimates rainfall and overestimates surface temperature over the entire domain of East Africa. The higher resolution HIRHAM5 (10km resolution) overestimates rainfall over high ground. The model bias could be due in part to the inadequacy of the observation networks in East Africa, represented in this thesis by the CRU and FEWS datasets. However, these two datasets draw on some different sources and neither do they have the same resolution. FEWS is a high resolution data (0.1 o ) gridded satellite-derived precipitation estimate covering the entire African continent while CRU datasets is a relatively low resolution (0.5 o ) dataset based on rain gauge monthly precipitation only; in addition , near surface temperature is also available. As no reliable wind observations exist, wind data was taken from the ERA-Interim reanalysis. The different observational datasets do not agree particularly well, which impedes evaluating the quality of the HIRHAM5 simulations, in particular the high resolution one. So while the higher resolution HIRHAM5 appears to be generally reliable, caution must be exercised in formulating conclusions from the results, especially over high ground and remote areas without adequate observation data. Under these constraints, the results suggest HIRHAM5 may be useful for assessing climate variability and change over East Africa. A weakness of the analysis presented here is that only one combination of GCM and RCM could be investigated in depth due to computer and time constraints. Therefore the results presented here, if used in application for climate change adaptation, should be considered in conjunction with a broader suite of data, such from the CORDEX programme. This has potential to increase the reliability of information about climate variability and change at a regional to local level necessary for impact assessment.

AB - Background: There is a high incidence of Mycobacterium tuberculosis (M tb) infection and active Tuberculosis (TB) disease among adolescents in high TB burden countries, such as South Africa (SA), which indicates that clinical trials assessing vaccine-induced protection are critical in this age group. In educating adolescents regarding TB and clinical trials it is important to ensure that this population has received some relevant prior information if they are approached for clinical research, as well as for the benefits to their own health. Method: Applied theatre was used to educate and inform adolescents to improve their knowledge about TB and clinical research. The script used was based on a young mother's decision to enroll her baby as a participant in a TB vaccine trial and the questions asked by her family and the community. The story played itself out in public transport, a local clinic and the participants' household, using singing, dancing and rap in the local dialect. The message was visually delivered by actors from the Worcester Senior Secondary (WSS) School's drama class in an adolescent-friendly format to learners. A pre-performance multiple choice knowledge survey was completed by the study population before they watched the play and approximately seven days after the play the same knowledge survey was completed as a post-test. Results: Of the total study population 4.56% of the adolescents had had TB previously and 39.15 % had been involved in TB research. A high number of the adolescents (97. 7 0 %) had heard about TB and 78. 39 % indicated that they heard about TB at school. The majority of adolescents knew that TB is contagious: 82.92 % in pre-and 97.26 % in post-test. The results for mode of prevention (covering your mouth when coughing / sneezing) in the pre-test for all the schools were above 9 1.28 %. In all tested schools combined there was a slight knowledge increase from pre-to post-test that TB is curable. There was a significant knowledge improvement (P=0.009) for the question: "TB can easily be cured if you take your treatment?" Reassuringly, 9 4.84 % (pre-test) and 9 2.78 % (post-test) indicated that they would consult a medical doctor or go to the clinic if they thought they had TB. Clinical research knowledge did not improve. Conclusion: Using applied theatre to sensitize a rural adolescent population to TB-related clinical research was a novel approach to educate and convey sensitive information to potential study participants. Through theatre, SATVI raised awareness and established strong partnerships with the Department of Basic Education (DoE), school principals, teachers and adolescents as well as indirectly with their parents. It created a platform to engage with the adolescents as well as sensitizing them for a future clinical trial.

Background: There is a high incidence of Mycobacterium tuberculosis (M tb) infection and active Tuberculosis (TB) disease among adolescents in high TB burden countries, such as South Africa (SA), which indicates that clinical trials assessing vaccine-induced protection are critical in this age group. In educating adolescents regarding TB and clinical trials it is important to ensure that this population has received some relevant prior information if they are approached for clinical research, as well as for the benefits to their own health. Method: Applied theatre was used to educate and inform adolescents to improve their knowledge about TB and clinical research. The script used was based on a young mother's decision to enroll her baby as a participant in a TB vaccine trial and the questions asked by her family and the community. The story played itself out in public transport, a local clinic and the participants' household, using singing, dancing and rap in the local dialect. The message was visually delivered by actors from the Worcester Senior Secondary (WSS) School's drama class in an adolescent-friendly format to learners. A pre-performance multiple choice knowledge survey was completed by the study population before they watched the play and approximately seven days after the play the same knowledge survey was completed as a post-test. Results: Of the total study population 4.56% of the adolescents had had TB previously and 39.15 % had been involved in TB research.

AB - Man is increasingly assuming conscious control over his physical environment. The impact of rapidly accelerating scientific and technological progress has resulted in the environment being increasingly man-made and man-influenced. The growing urban population has necessitated building at a rate and quantity greater than ever before. Enormous resources, both human and material, are being channelled on an unprecedented scale into the planning, designing and construction of new environments for human use. Whilst this tide of energy and activity continues to surge forward, creating vast urban and suburban. developments, very little energy and resources have, by comparison, been directed towards critically assessing the impact that these built environments have on people, and the extent to which they are responsive to human needs and aspirations. It has become critical for the architect to be made fully aware of the human implications of the physical environment he is creating. Concern for the human element has been eclipsed by the current pre-occupation of the design profession with technology and economics which have become the dominant design imperatives.

AB - This thesis examines the idea of the second-personal reason, as advocated by Stephen Darwall in his influential book, The Second-Person Standpoint. A second-personal reason is a reason that exists not in the world, nor in a single individual's mind, but in the relationship between two (or more) people: second-personal reasons are reasons given to a first person by a second. The idea of second-personality is gaining ground in contemporary Metaethics - as well as in Psychology and the Philosophy of Mind - and this thesis aims to give a novel presentation of Darwall's Second-Personal metaethic that makes clear just why it is so popular. As I will present it, Darwall's Second-Personal account is a fresh kind of metaethic that promises to give us the 'best of both worlds', enjoying all the benefits of traditional metaethics, such as Realism and Neo-Kantianism, while simultaneously overcoming their respective defects. However, I go on to argue that Darwall's Second-Personal account ultimately fails. Contrary to initial appearances, Darwall's Second-Personal account does not present any significant advances, and, whatever advantages it does appear to possess, it possesses only by virtue of its covert, illicit appeal to Realism. In particular, I argue that we have no grounds for believing that there are indeed such things as second-personal reasons in the first place. After all, who are you to tell me what to do? In response to this criticism, I offer a new, different reading of Darwall's Second-Personal account, according to which it is not to be read as one amongst other metaethics, such as Realism or Neo-Kantianism. It is, rather, to be read as an entirely different approach to Metaethics. Taking my inspiration from Gilbert Ryle, I cash this out in terms of the Second-Personal account's reacting to the category-mistakenness of traditional Metaethics, by reconceiving moral reasons as belonging to a different kind of category altogether. When we understand morality correctly, as belonging to its proper category, then it follows that moral reasons are indeed second-personal. They are moral reasons of our own.

AB - Most human beings experience the pull of three different daily timers, the solar clock, their endogenous circadian clock and the societal clock. Solar time is generated by the Earth’s revolution on its axis, resulting in its surface being alternately exposed to and shielded from the sun every 24 hours. The endogenous clock, or circadian oscillator, is driven by a network of transcriptional translational feedback loops, and has a period of close to 24 hours. The circadian oscillator is synchronised to the 24 hour light-dark cycle of the solar clock. The third timer is the standardised societal clock that organises and schedules work, school, transport, appointments and free time in a 24 hour period. The way an individual’s endogenous clock synchronises to the solar clock, through advances or delays relative to sunrise and sunset, results in a phenomenon known as diurnal preference or chronotype. A person may have a morning-chronotype, where they enjoy rising and being active early in the day, an evening-chronotype where they prefer to be active later in the day into the late night, retiring in the early morning hours, or have no strong preference for early or late rising. This renders it easy for some to cope with the demands of the societal clock and others to struggle. Chronotype has both genetic and environmental influences. As society’s schedule is governed by the standardised clock, it was hypothesised that chronotype may be influenced by one’s longitudinal location within a time zone. South Africa presents an interesting case because although it uses just one time zone, in the most Easterly regions of the country, the sun rises and sets up to an hour earlier than in the most Westerly regions throughout the year. Sunrise times have an impact on the way the endogenous clock synchronises to the solar clock. It was hypothesised firstly, that South Africans living in the East of the country may have a greater preference for mornings (more morningchronotypes) than those living in the West; and secondly, that this difference would not be due to genetic differences in the populations, particularly two gene polymorphisms previously shown to influence chronotype. Therefore the aims of this study were to describe and compare the distribution of chronotype in Eastern (n=222) and Western (n=205) sample populations with the use of a validated tool, the Horne–Östberg Morningness, Eveningness Questionnaire. Secondly to describe the genotype and allelic frequency distributions of the PER2 single nucleotide polymorphism (SNP) G3853A (rs934945) in the Eastern (n= 184) and Western (n=186) populations, and the PER3 variable number tandem repeat (VNTR) polymorphism in the Eastern (n=143) and Western (n=176) populations from buccal cell samples. There was a significantly higher proportion of morning-types in the Eastern population (60.6%) than in the Western population (40.5%) (p<0.001). Whereas there were higher proportions of neither-types and evening-types in the Western population (50.8% and 8.7% respectively) than in the Eastern population (35.1% and 4.3% respectively) (p<0.001). There were no significant differences in distribution of the PER2 genotype (p=0.121) and allele frequencies (p=0.051) between the Eastern and Western populations nor in the PER3 genotype (p=0.879) and allele (p=0.075) frequencies. Although previous studies have shown associations between chronotype and PER2 G3853A and PER3 VNTR genotypes, no significant associations were observed in either the Eastern (PER2 p=0.769; PER3 p=0.221) or the Western (PER2 p=0.584; PER3 p=0.733) populations. These findings indicate that, in South African populations, longitude influences chronotype independently of genotype. Factors that may contribute to this may be the difference in the rising times of the sun, which is exacerbated to some extent by the study areas being at dissimilar latitudes and thus experiencing slight differences in climate. The impact of the differences in chronotype but the maintenance of the same societal temporal organisation in the Eastern and Western regions were not assessed. However, they may be revealed by investigating certain general health indicators in such as quality of sleep and prevalence of depressive symptoms which are affected when there is incongruence between societal time and endogenous time.

AB - The performance of twelve deaf subjects with an extremely poor comprehension of language and control over language structure, was compared with that of a normally hearing control group on four tasks of formal thinking. Six deaf subjects performed at the formal operational level on at least one task, supporting the hypothesis that formal thinking can develop to its primary formation in the severely linguistically deprived. The implications of the findings for certain cognitive theories and for educational practice are presented.

AB - This study reviewed community-based directly observed treatment and the conventional approach to tuberculosis management in order to find cost-effective approach. Both patient and health system cost data were used. Hospital cost data were collected from a mission hospital in rural Zambia for the periods 1989 and 1997. Patient cost data were collected from a sample of 50 patients in terms of time and travel costs. The cure rate was used as the measure of effectiveness. Results showed that community-based DOT is the most cost-effective approach because of its reduced costs to the patients and health system. Finally, it was also found that community-based DOT is the most viable economic option given the existing resource constraints. Suggestions for future study are offered and limitations of research are explored.

This study reviewed community-based directly observed treatment and the conventional approach to tuberculosis management in order to find cost-effective approach. Both patient and health system cost data were used. Hospital cost data were collected from a mission hospital in rural Zambia for the periods 1989 and 1997. Patient cost data were collected from a sample of 50 patients in terms of time and travel costs. The cure rate was used as the measure of effectiveness. Results showed that community-based DOT is the most cost-effective approach because of its reduced costs to the patients and health system. Finally, it was also found that community-based DOT is the most viable economic option given the existing resource constraints. Suggestions for future study are offered and limitations of research are explored.

AB - The radiocarbon ages of mollusc shells from the Bogenfels Pan on the hyper arid southern coast of Namibia provide constraints on the Holocene evolution of sea level and, in particular, the mid-Holocene highstand. The Bogenfels Pan was flooded to depths of 3 m above mean sea level (amsl) to form a large subtidal lagoon from 7300 to 6500 calibrated radiocarbon years before present (cal yr BP). The mollusc assemblage of the wave sheltered lagoon includes Nassarius plicatellus, Lutraria lutraria, and the bivalves Solen capensis and Gastrana matadoa, both of which no longer live along the wave-dominated southern Namibian coast. The radiocarbon ages of mollusc shell from a gravely beach deposit exposed in a diamond exploration trench indicate that sea level fell to near or 1 m below its present-day position between 6500 and 4900 cal yr BP. The rapid emergence of the pan between 6500 and 4900 cal yr BP exceeds that predicted by glacio-isostatic models and may indicate a 3-m eustatic lowering of sea level. The beach deposits at Bogenfels indicate that sea level rose to 1 m amsl between 4800 and 4600 cal yr BP and then fell briefly between 4600 and 4200 cal yr BP before returning to 1 m amsl. Since 4200 cal yr BP sea level has remained within one meter of the present-day level and the beach at Bogenfels has prograded seaward from the delayed arrival of sand by longshore drift from the Orange River. A 6200 cal yr BP coastal midden and a 600 cal yr BP midden 1.7 km from the coast indicate sporadic human utilization of the area. The results of this study are consistent with previous studies and help to refine the Holocene sea-level record for southern Africa.

AB - Despite being internationally recognised as an economic powerhouse of the African continent, South Africa struggles to overcome certain socio-economic problems, which predominantly stem from the inequalities within its society. One of the most important areas of prevailing concern is high unemployment, particularly amongst the youth segment of the population. Approximately 42% of South Africans under the age of 30 are unemployed, a fate shared by less than 17% of those above 30 years of age. The South African government appropriately sought to ensure a better future for all its citizens by 'creating', or facilitating the creation, of more jobs. As part of its 'program of action', one of the initial steps was to enact the Employment Tax Incentive Act, No. 26 of 2013 ('ETIA'). The following extract is from the Explanatory Memorandum on the Employment Tax Incentive Bill, 2013: "High youth unemployment means young people are not gaining the skills or experience needed to drive the economy forward. (…) In response to the high rate of youth unemployment, government wishes to implement an incentive mainly aimed at encouraging employers to hire young and less experienced work seekers, as stated in the National Development Plan. The incentive is one among many that will fall under the umbrella of government's youth employment strategy, the National Youth Accord, which outlines a program of action to address youth unemployment." The primary aim of this study is to conduct a detailed analysis of the ETIA in order to ultimately evaluate its merits, i.e. by expressing an opinion on whether or not it is assisting in combatting youth unemployment. The analysis compares similar types of legislation that have been implemented, both successfully and unsuccessfully, in other countries in attempts to address similar unemployment issues. This paper reflects events, legislation and published literature as at 1 December 2015.

AB - This dissertation concerns the development of a synthetic route towards novel cysteine-based glycan-binding probes, for incorporation into glycoarrays and or similar applications used in assays of glycan-recognition phenomena. The need to systematically characterize the glycome and decipher the range of glycosylation patterns found in living cells, has prompted the development of molecular tools such as glycoarrays and related systems for immobilizing defined carbohydrate structures. The preparation of these probes requires access to building blocks where the core structure has defined glycans together with appropriate linkers, and the amino acid cysteine is explored here as one such structure. In particular, this dissertation describes the synthesis of a S-glucosylcysteine derivative SGC, or methyl N-(6-aminohexanoyl)-S-(β-D-glucopyranosyl)-L-cysteinate trifluoroacetate 67, as well as its 2-acetamido analogue SAGC, or methyl N-(6-aminohexanoyl)-S-(2-acetamido-2-deoxy-β-D-glucopyranosyl)-L-cysteinate trifluoroacetate 74. The first approach involved initial preparation of N-(4-azidobutanoyl)-L-cysteine 12 and attempted reaction of this with 1,2,3,4,6-penta-O-acetyl-β-D-glucopyranose 3 to form the initial target of this dissertation, bis-glucoside 13. This was not successful, but repetition of the reported reaction involving the use of N-acetyl-L-cysteine 4 provided a modest yield of partially purified bis-glucosyl cysteine (BGC, 1). A mechanism for this one-pot, sequential bis-glucosylation is proposed. The limitations of the one-pot procedure led to investigation of alternative methods for the step-wise introduction of sugar units to the cysteine core. For this purpose the cysteine derivative, methyl N-(6-((tert-butoxycarbonyl)amino)hexanoyl)-L-cysteinate 40, was prepared and reacted with 3 to obtain a fully protected precursor of the target SGC. However, inefficiencies in this procedure led to investigation of an alternative strategy for preparation of SGC.

AB - The purpose of this thesis is it to investigate the socio-political conditions that gave rise to right-wing populism (RWP) in Germany and Hungary. It ascertains reasons for increasing right-wing populist attitudes in these two countries by tracing the emergence of the German Alternative für Deutschland (AfD) and the Hungarian Movement for a better Hungary (Jobbik).

AB - The phenomenon of ridging is known to occur in most ferritic stainless steels and is manifested during deformation of sheet material. It results in the formation of a corrugated profile with ridges always elongated in the rolling direction of the sheet and are typically around 1 mm in wavelength. The formation of a ridged profile, while not having a detrimental effect of the mechanical properties, results in the product having an unatractive surface finish. Thus there is a drive to find a thermomechanical process to minimise the severity of ridging in the final sheet product. In this regard, the purpose of this investigation was to establish the influence of three thermomechanical (TMP) variables on the ridging severity. The samples in this investigation represented: two zones of the initial starting structure, with equiaxed of solunar grains; four hot rolling finish temperatures (HRFT), 700°C, 800°C, 900°C and 1000°C; and two colling methods after hot rolling, quench and slow cool versus slow cool. Each sample completed the TMP cycle, was elongated to 20% strain and the topography on the surface measured and compared.

AB - Over the past decades, the issue of low frequency oscillations has been of major concern to power system engineers. These oscillations range from 0.1 to 3Hz and tend to be poorly damped especially in systems equipped with high gain fast acting AVRs and highly interconnected networks. If these oscillations are not adequately damped, they may sustain and grow, which may lead to system separation and loss of power transfer.

AB - The steam generator in a pressurized water reactor power plant acts as a fission product barrier between primary and secondary system. Material failure of the tube bundle barrier could therefore lead to a release of radioactive product into the secondary side. Several repair methods have been used to address tube leakage, with the most popular being tube plugging. The objective of this study was to quantify the effect of tube plugging on the thermal performance of a steam generator. For this purpose, the systems computational fluid dynamics (CFD) software Flownex® was used. First, a Flownex® model of the steam generator was developed and validated via comparison of the results to a validated model from the literature. Following this, a hydro-thermal analysis was performed to determine the effect of the tube plugging on the thermal performance under normal operational conditions (excluding the possibility of a tube rupture). Tube plugging of up to 20% was investigated. The model predicted the following effects: decrease in heat transfer, primary coolant mass flowrate and primary outlet pressure. Further, primary flow velocity, pressure drop and outlet temperature increase with increasing tube plugging. On the secondary side, tube plugging lowers the mixture quality in the boiling region and steam production while the re-circulation ratio was increased. Lastly, the model predicted a plugging ratio limit of 17.3%. Beyond this point, the steam generator does not extract sufficient heat from the reactor at 100% power.
