- ItemOpen AccessAre country reputations for good and bad leadership on AIDS deserved?: an exploratory quantitative analysis(Oxford University Press, 2008) Nattrass, NicoliSome countries (e.g. Brazil) have good reputations on AIDS policy, whereas others, (notably South Africa) have been criticized for inadequate leadership. Cross-country regression analysis reveals that these 'poster children' for AIDS leadership have indeed performed better or worse than expected given their economic and institutional constraints and the demographic and health challenges facing them. Regressions were run on HAART coverage (number on highly active antiretroviral therapy as percentage of total need) and MTCTP coverage (pregnant HIV-positive women accessing mother-to-child-transmission prevention services as percentage of total need). Brazil, Cambodia, Thailand and Uganda (all of whom have established reputations for good leadership on AIDS performed consistently better than expected - as did Burkina-Faso, Suriname, Paraguay Costa Rica, Mali and Namibia. South Africa, which has the worst reputation for AIDS leadership, performed significantly below expectations - as did Uruguay and Trinidad and Tobago. The paper thus confirms much of the conventional wisdom on AIDS leadership at country level and suggests new areas for research.
- ItemOpen AccessThe development and location of industries in greater Cape Town, 1652-1972(1973) Whittingdale, JohnMany geographical stud±es have been made of the whole or parts of the City of Cape Town. These include a short general study of the structure and functions of the city from 1652 to 1958 by William J. Talbot Cape Town as a World City (in Zum Problem der Weltstadt), several sociological studies by P. Scott and a delimitation of the C.B.D. boundary of the city by D.Davies and 'The Growth and Development of Cape Town' by Margaret Marshall. Others include studies of individual industrial suburbs. It does not appear that a complete study of the industrial structure of the city has ever been attempted. In this thesis an attempt has therefore been made to trace, as far as possible, the growth and development of industry in Greater Cape Town from the time of the first settlement in 1652.
- ItemOpen AccessGeomorphology of the Cape Peninsula(1984) King, Wilfred Basil; King, Wilfred Basil; Impey, L L H; Impey, L L HIt is axiomatic that we live in a world characterized by opposites. We are thus aware of day and night, winter and summer, uplift and subsidence, lithosphere and hydrosphere, upland and lowland areas, past and present - the list is endless. This dichotomy or ambivalence is present in this study as well. On the one hand it attempts to trace the genesis and geornorphic history of the areal matrix, and on the other it looks at the contemporary landscape and the changes wrought through time. The writer is of the opinion that the past cannot be ignored, since the present physical landscape can be explained only in the context of geomorphic evolution. This is generally acceptable since today is tho child of yesterday and the father of tomorrow. Other aspects which are examined include evidence of changes wrought in the past in tho form of denudation or erosion surfaces, the relationship between the underlying geological structure and present landforms, together with the strong structural and directional control which is manifested within the study area. Present drainage patterns are examined, whilst the role played by running water and the sea in creating and changing the physical landscape is a theme which runs through the greater part of this dissertation.
- ItemOpen AccessInferring Process from Pattern in Plant Invasions: A Semimechanistic Model Incorporating Propagule Pressure and Environmental Factors(2003) Rouget, Mathieu; Richardson, David MAbstract: Propagule pressure is intuitively a key factor in biological invasions: increased availability of propagules increases the chances of establishment, persistence, naturalization, and invasion. The role of propagule pressure relative to disturbance and various environmental factors is, however, difficult to quantify. We explored the relative importance of factors driving invasions using detailed data on the distribution and percentage cover of alien tree species on South Africas Agulhas Plain (2,160 km2). Classification trees based on geology, climate, land use, and topography adequately explained distribution but not abundance (canopy cover) of three widespread invasive species (Acacia cyclops, Acacia saligna, and Pinus pinaster). A semimechanistic model was then developed to quantify the roles of propagule pressure and environmental heterogeneity in structuring invasion patterns. The intensity of propagule pressure (approximated by the distance from putative invasion foci) was a much better predictor of canopy cover than any environmental factor that was considered. The influence of environmental factors was then assessed on the residuals of the first model to determine how propagule pressure interacts with environmental factors. The mediating effect of environmental factors was species specific. Models combining propagule pressure and environmental factors successfully predicted more than 70% of the variation in canopy cover for each species.

- ItemOpen Access'n Didakties-pedagogiese analise van die doel van die onderrig van aardrykskunde in die primêre skool(1978) Visagie, J H B; Erasmus, O CSoos in die titel van die verhandeling aangekondig word, is hierdie ondersoek toegespits op tweërlei aspekte: enersyds die doelstelling van die onderrig van Aardrykskunde in die primêre skool, en andersyds 'n didaktiespedagogiese analise van sodanige doelstelling. So 'n omlyning van die navorsingsveld sou miskien vaag aandoen indien daar nie op 'n verantwoordbare wyse rekening gehou word met sekere fundamentele konsepte of begrippe wat in die titel weerspieël word nie. Daarom wil ons spesifiek die volgende uitsonder en meer volledig belig: didakties-pedagogies, doelstelling, onderrig, Aardrykskunde en primêre skool.
- ItemOpen AccessSpatial patterns of social differentiation among the Coloureds in Greater Cape Town(1980) Morris, Roselynne Laraine; Cook, G PThe concern of this study is to identify social areas among the coloured population of Greater Cape Town and to see if these are recognisable in physical space; i.e. if once social areas are recoqnised, whether the patterns of differing social status can be related to that of adjacent areas. If socio-economic status is assumed to be reflected in housing type and quality, then physical environment and interaction between adjacent areas is likely to play an important role in creating an environment that is perceived to have a particular character and status. As a result, contiguity will have great significance in the emergence of distinct socio-economic sub-areas. It is therefore essential to concentrate a study of this type on adjacent ESD's and to regard the four major concentrations of residential areas as separate entities. By dealing primarily with contiguous ESD's each forming separate residential concentrations, it carries no implication that there is no interaction between the different residential concentrations. Together they form a total system and areas of similar socio-economic status may develop in all or some of the residential concentrations.
- ItemOpen AccessThe abundances and distribution of some trace elements in some selected South African shales(1971) Hofmeyr, Pierre Karel; Nigel WordenThis thesis is the study of a single farm, Klaver Valley in the Darling district, 1812 - 1898. Chapter One provides a physical view of Klaver Valley from 1812 to 1898 showing the changes in the landscape and production of grains, wine and wool over the period. It argues that these changes occurred as a direct result of external market forces. Chapter Two focuses on the changes which occurred in the labour process from the early 1800s to 1898, arguing that the main impetus for change came from mechanisation of harvesting in the 1820s and 1850s. Chapter Three explores the notion of a capitalist farmer and argues that Duckitt and later Ruperti can be categorised as capitalist farmers. The main thrust of their progressive capitalization occurred before the 1850s and it did so as a result of the system of informal credit which existed at farm level among farmers, allowing for re-investment and survival of cash flow. Chapter Four studies the process of proletarianisation which accompanied the capitalist development of the farm and its farmers. While taking account of the existence of a small number (3) of sharecroppers on the farm in the 1840s, 1870s and 1890s, this chapter argues that by the early 1830s, the farm was operating on the back of fully proletarianised labour. Composition of the labour force, wages and tasks, the work of women and the change from resident and permanent to casual labour from the 1820s to the 1890s, form some of the main focuses of this chapter. Chapter Five explores the nature of the relationship between the farmer and workers from - 1898, the two increasingly alienated from each other by the encroachment of the overseer. It argues that capitalist relations of production developed in the context of paternalism throughout although it was increasingly shaped by the cash-oriented relationship.
