    Designing a course model for distance-based online bioinformatics training in Africa: The H3ABioNet experience
    (2017) Maslamoney, Suresh; Domelevo Entfellner, Jean-Baka; Guerfali, Fatma Z; Saunders, Colleen; Mansour Alzohairy, Ahmed; Cloete, Ruben; Mulder, Nicola
    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.

    Factors affecting how the youth in the townships use internet to seek employment: case of a township in Cape Town
    (2019) Kunene, Khaya; Chigona, Wallace
    Problem Statement: South Africa is currently facing a challenge of youth unemployment. The hardest hit are those from low income communities, as they in addition have limited access to information. The Internet has proven to be one of the ways in which recruitment is done and failure to access reduces the opportunities. The purpose of the research: The main objective of this study was to understand how the youth living in the townships use the Internet to seek for employment. The purpose of this study is to assess how the Internet use affect the youth when searching for employment. Design/methodology/ approach: An interpretivist approach was employed to understand how the youth seek employment. This study used a qualitative approach to collect the data. Interviews were done using semi-structured questions. Alampay (2006) Capability Approach (CA) was used as a guide to conceptualise how the youth from low-income communities use the Internet to find employment. Borrowing from the four main constructs (conversion factors, freedom, capabilities and functionings) employed by Alampay (2006) in his model, this study operationalised the Alampay (2006) CA model by adding the ICT commodities as the fifth construct. The CA was chosen as an appropriate framework for this study because the framework focuses on what humans are able to do and achieve when presented with the available ICT resources. Findings: The findings demonstrate that the lack of resources, income, information and digital skills affected the individual capabilities to effectively use the Internet when seeking employment. The success rate in finding a job using the Internet was low among job seekers. Commodities, individual differences, social and environmental factors affected how the youth (18-34 years) from low-income communities use the Internet to find employment. In addition, crime, poor network coverage, expensive data bundles and limited access to ICT resources were among the key factors that contributed to limited use of the Internet among job seekers. Research Contribution: This study seeks to close the gap in limited knowledge available in developing countries with regards to the use of the Internet among job seekers. Therefore, based on the study findings, this thesis has contributed towards adding value to the body of knowledge within the field of Information Systems. In addition, the findings can contribute towards assisting policy makers in solving challenges faced by the unemployment youth in developing countries when using technology to find employment.

    myKaryoView: a light-weight client for visualization of genomic data
    (Public Library of Science, 2011) Jimenez, Rafael C; Salazar, Gustavo A; Gel, Bernat; Dopazo, Joaquin; Mulder, Nicola; Corpas, Manuel
    The Distributed Annotation System (DAS) is a protocol for easy sharing and integration of biological annotations. In order to visualize feature annotations in a genomic context a client is required. Here we present myKaryoView, a simple light-weight DAS tool for visualization of genomic annotation. myKaryoView has been specifically configured to help analyse data derived from personal genomics, although it can also be used as a generic genome browser visualization. Several well-known data sources are provided to facilitate comparison of known genes and normal variation regions. The navigation experience is enhanced by simultaneous rendering of different levels of detail across chromosomes. A simple interface is provided to allow searches for any SNP, gene or chromosomal region. User-defined DAS data sources may also be added when querying the system. We demonstrate myKaryoView capabilities for adding user-defined sources with a set of genetic profiles of family-related individuals downloaded directly from 23andMe. myKaryoView is a web tool for visualization of genomic data specifically designed for direct-to-consumer genomic data that uses publicly available data distributed throughout the Internet. It does not require data to be held locally and it is capable of rendering any feature as long as it conforms to DAS specifications. Configuration and addition of sources to myKaryoView can be done through the interface. Here we show a proof of principle of myKaryoView's ability to display personal genomics data with 23andMe genome data sources. The tool is available at: http://mykaryoview.com .

    Problematic use of the Internet is a unidimensional quasi-trait with impulsive and compulsive subtypes
    (2019-11-08) Tiego, Jeggan; Lochner, Christine; Ioannidis, Konstantinos; Brand, Matthias; Stein, Dan J; Yücel, Murat; Grant, Jon E; Chamberlain, Samuel R
    Abstract Background Problematic use of the Internet has been highlighted as needing further study by international bodies, including the European Union and American Psychiatric Association. Knowledge regarding the optimal classification of problematic use of the Internet, subtypes, and associations with clinical disorders has been hindered by reliance on measurement instruments characterized by limited psychometric properties and external validation. Methods Non-treatment seeking individuals were recruited from the community of Stellenbosch, South Africa (N = 1661), and Chicago, United States of America (N = 827). Participants completed an online version of the Internet Addiction Test, a widely used measure of problematic use of the Internet consisting of 20-items, measured on a 5-point Likert-scale. The online questions also included demographic measures, time spent engaging in different online activities, and clinical scales. The psychometric properties of the Internet Addiction Test, and potential problematic use of the Internet subtypes, were characterized using factor analysis and latent class analysis. Results Internet Addiction Test data were optimally conceptualized as unidimensional. Latent class analysis identified two groups: those essentially free from Internet use problems, and those with problematic use of the Internet situated along a unidimensional spectrum. Internet Addiction Test scores clearly differentiated these groups, but with different optimal cut-offs at each site. In the larger Stellenbosch dataset, there was evidence for two subtypes of problematic use of the Internet that differed in severity: a lower severity “impulsive” subtype (linked with attention-deficit hyperactivity disorder), and a higher severity “compulsive” subtype (linked with obsessive-compulsive personality traits). Conclusions Problematic use of the Internet as measured by the Internet Addiction Test reflects a quasi-trait - a unipolar dimension in which most variance is restricted to a subset of people with problems regulating Internet use. There was no evidence for subtypes based on the type of online activities engaged in, which increased similarly with overall severity of Internet use problems. Measures of comorbid psychiatric symptoms, along with impulsivity, and compulsivity, appear valuable for differentiating clinical subtypes and could be included in the development of new instruments for assessing the presence and severity of Internet use problems.

    Supervised and unsupervised self-testing for HIV in high-and low-risk populations: a systematic review
    (Public Library of Science, 2013) Pai, Nitika Pant; Sharma, Jigyasa; Shivkumar, Sushmita; Pillay, Sabrina; Vadnais, Caroline; Joseph, Lawrence; Dheda, Keertan; Peeling, Rosanna W
    Background: Stigma, discrimination, lack of privacy, and long waiting times partly explain why six out of ten individuals living with HIV do not access facility-based testing. By circumventing these barriers, self-testing offers potential for more people to know their sero-status. Recent approval of an in-home HIV self-test in the US has sparked self-testing initiatives, yet data on acceptability, feasibility, and linkages to care are limited. We systematically reviewed evidence on supervised (self-testing and counselling aided by a health care professional) and unsupervised (performed by self-tester with access to phone/internet counselling) self-testing strategies. Methods and Findings: Seven databases (Medline [via PubMed], Biosis, PsycINFO, Cinahl, African Medicus, LILACS, and EMBASE) and conference abstracts of six major HIV/sexually transmitted infections conferences were searched from 1st January 2000–30th October 2012. 1,221 citations were identified and 21 studies included for review. Seven studies evaluated an unsupervised strategy and 14 evaluated a supervised strategy. For both strategies, data on acceptability (range: 74%–96%), preference (range: 61%–91%), and partner self-testing (range: 80%–97%) were high. A high specificity (range: 99.8%–100%) was observed for both strategies, while a lower sensitivity was reported in the unsupervised (range: 92.9%–100%; one study) versus supervised (range: 97.4%–97.9%; three studies) strategy. Regarding feasibility of linkage to counselling and care, 96% (n = 102/106) of individuals testing positive for HIV stated they would seek post-test counselling (unsupervised strategy, one study). No extreme adverse events were noted. The majority of data (n = 11,019/12,402 individuals, 89%) were from high-income settings and 71% (n = 15/21) of studies were cross-sectional in design, thus limiting our analysis. Conclusions: Both supervised and unsupervised testing strategies were highly acceptable, preferred, and more likely to result in partner self-testing. However, no studies evaluated post-test linkage with counselling and treatment outcomes and reporting quality was poor. Thus, controlled trials of high quality from diverse settings are warranted to confirm and extend these findings.

    The Role of the Internet in Alleviating Social Exclusion: The Case of the Western Cape Province
    (2008) Chigona, Wallace; Mbhele, Fidel
    Information and Communication Technology (ICT) is perceived by many as a means of tackling the problem of social exclusion. This perspective has resulted in governments and donor agencies investing in the establishment of Internet access points (e.g. telecentres) in areas which are perceived to be socially excluded. Yet, beyond the belief of inherently beneficial ICTs, there has been little empirical work done to evaluate the impact of ICTs, notably the Internet, in addressing social exclusion. In this paper, we report on a study investigating whether the Internet contributes to alleviating social exclusion in developing countries. The cross-sectional study uses a qualitative research approach on four communities with government-funded Internet access points in the Western Cape Province, South Africa. The major finding of the paper is that the Internet plays a minimal role in alleviating social exclusion, and only a few members of the communities stand to benefit. The Internet on its own is not sufficient to address the problems of social exclusion; there are necessary preconditions which should be in place for the Internet to have an impact.

    Usage of Twitter by state-owned enterprises to communicate with customers: A case of Transnet South Africa
    (2020) Mello, Tsebiso Lisbeth; Ferreira, Caitlin
    Social media is proving to be a critical factor for firms moving towards digital marketing strategies. Substantial economic advantage is gained when companies make use of social media platforms such as Twitter to modernise their businesses and start interactive communication with their target market. Social media can have a great impact on the efficiency and performance of state-owned enterprises, which are often plagued by information irregularities that compromise information disclosure and lower the standards of accountability within the state-owned enterprises. Without social media, customers are often unable to evaluate the product and services that the state-owned enterprise is offering before making an offer. An interpretivist research paradigm was adopted and informed this study which applied a mono qualitative research methodology. Sample elements were selected using non-probability purposive and convenience sampling techniques. Data was gathered through a pre-designed interview guide with open-ended questions from the research site. In addition, the case study research design was used in this study. All interview transcriptions were recorded with the aid of a voice recorder and exported to NVivo 11 for cleaning and coding, resulting in emerging themes. Thematic data analysis was performed on the data sets, allowing a detailed discussion of each theme in line with research objectives. The study established that adopting and using social media was the appropriate strategy for firms. Firms, especially state-owned enterprises, reached a larger audience. In addition, the study established that the quality of content uploaded and shared on social media should be of very high quality to project a positive image of the organisation. Appointing dedicated senior personnel to manage the social media strategy enhanced the effectiveness of social media. The study recommended that further research be conducted on other types of social media to allow organisations a wider selection of choices. The study indicated that employees were compelled to use Twitter; thus, a policy shift in the use of social media required managers to put in place Information Communications Technology and Privacy and Security Policies. In order to educate everyone in the organisation, management had to ensure that its policies did not infringe on human rights.

    Uses and Gratifications of Computers in South African Elderly People
    (2015) Bosch, Tanja; Currin, Bronwyn
    Drawing on in-depth interviews conducted with residents at an old-aged home in Cape Town, South Africa, this study examines the main uses and gratifications elderly people get from computers. While the research focus in Africa has been on the health of elderly people, particularly with respect to HIV/AIDS, there is little research into their adoption of new technologies, as the research focus with respect to that topic has been primarily on youth. This study found that the participants use email and social media to maintain contact with family and friends outside of, and sometimes even within the neighborhood. Furthermore, keeping in contact involved not only communication, but also observation of activities - like news, photographs and discussions. Using a uses and gratifications framework, this study found that participants felt connected with society both through their communication with and observation of people, and through keeping themselves informed about news and current interest topics. By using the Internet the elderly people communicated with more people than they had before. Some of the participants felt less isolated and lonely because of their computer use. Nevertheless, use of computers did not weaken their interpersonal contact outside of computer use. A partir de entrevistas en profundidad, realizadas en un hogar de la tercera edad en Ciudad del Cabo (Sudáfrica), este estudio analiza los principales usos y gratificaciones que reciben las personas mayores en interacción con los ordenadores. En África, mientras el énfasis investigador se ha puesto en los últimos años en la salud de los mayores, especialmente en cuanto al SIDA, existe muy poca investigación sobre el uso de los mayores en cuanto a nuevas tecnologías, ya que la investigación en relación con las mismas se ha centrado principalmente en la juventud. En este estudio se halló que los participantes utilizan el correo electrónico y las redes sociales para mantener el contacto con familiares y amigos y a veces incluso con su vecindario. Además, mantener el contacto suponía no solo comunicación, sino también observación de actividades, como noticias, fotografías y conversaciones. En el contexto de los usos y gratificaciones, el trabajo ha evidenciado que los participantes se sentían conectados con la sociedad, tanto por su comunicación como por la observación de las personas, y por mantenerse informados de las noticias y los temas de interés actuales. Mediante el uso de Internet, las personas de edad avanzada se comunicaban mucho más de lo que antes se habían comunicado con otras personas. Algunos de los participantes se sentían menos aislados y solos, debido a su uso del ordenador. Sin embargo, se demostró también que el uso de los ordenadores no obstaculizó los contactos interpersonales tradicionales.

    Will an unsupervised self-testing strategy for HIV work in health care workers of South Africa? A cross sectional pilot feasibility study
    (Public Library of Science, 2013) Pai, Nitika Pant; Behlim, Tarannum; Abrahams, Lameze; Vadnais, Caroline; Shivkumar, Sushmita; Pillay, Sabrina; Binder, Anke; Deli-Houssein, Roni; Engel, Nora; Joseph, Lawrence; Dheda, Keertan
    BACKGROUND: In South Africa, stigma, discrimination, social visibility and fear of loss of confidentiality impede health facility-based HIV testing. With 50% of adults having ever tested for HIV in their lifetime, private, alternative testing options are urgently needed. Non-invasive, oral self-tests offer a potential for a confidential, unsupervised HIV self-testing option, but global data are limited. METHODS: A pilot cross-sectional study was conducted from January to June 2012 in health care workers based at the University of Cape Town, South Africa. An innovative, unsupervised, self-testing strategy was evaluated for feasibility; defined as completion of self-testing process (i.e., self test conduct, interpretation and linkage). An oral point-of-care HIV test, an Internet and paper-based self-test HIV applications, and mobile phones were synergized to create an unsupervised strategy. Self-tests were additionally confirmed with rapid tests on site and laboratory tests. Of 270 health care workers (18 years and above, of unknown HIV status approached), 251 consented for participation. FINDINGS: Overall, about 91% participants rated a positive experience with the strategy. Of 251 participants, 126 evaluated the Internet and 125 the paper-based application successfully; completion rate of 99.2%. All sero-positives were linked to treatment (completion rate:100% (95% CI, 66.0-100). About half of sero-negatives were offered counselling on mobile phones; completion rate: 44.6% (95% CI, 38.0-51.0). A majority of participants (78.1%) were females, aged 18-24 years (61.4%). Nine participants were found sero-positive after confirmatory tests (prevalence 3.6% 95% CI, 1.8-6.9). Six of nine positive self-tests were accurately interpreted; sensitivity: 66.7% (95% CI, 30.9-91.0); specificity:100% (95% CI, 98.1-100). Interpretation Our unsupervised self-testing strategy was feasible to operationalize in health care workers in South Africa. Linkages were successfully operationalized with mobile phones in all sero-positives and about half of the sero-negatives sought post-test counselling. Controlled trials and implementation research studies are needed before a scale-up is considered.
