- Description: Publisher version , Teaching Excellence Awards have raised the profile of teaching as a scholarly project. There are however a number of questions about what constitutes teaching excellence and how ‘excellence’ is understood in current higher education. In a post-colonial South Africa, where significant injustices permeate our society, we question whether excellence can be understood in a generic manner. Furthermore, we argue that as universities are a public good, teaching excellence needs to explicitly attend to the ways in which universities contribute to broad goals of transformation and inclusivity. We analysed data from the national Teaching Excellence Awards and 13 South African universities’ awards to interrogate the discourses that underpin ‘excellence’ in this context of social inequality. We found that while the awards have gone some way to enhancing the position of teaching in institutions, ‘excellence’ was largely articulated in fairly generic ways which failed to take into account the enablements and constraints of the discipline and the institution. Furthermore, the guidelines and criteria privilege a decontextualised notion of excellence that seeks a ‘gold standard’ and validates performativity, rather than a contextualised response to the needs of the students.

- Description: There are two sides to every story. You’ve surely heard that before. Well, it is true. Sometimes there are even three or four sides to a story. It depends how many people were there to tell the tale. Behind every story there is a writer. Behind a picture there is a photographer. And they are ordinary people, like you and me. They eat, sleep and play like the rest of us. Like us, they have their own ideas and feelings about the world. And these ideas show in their stories, books or photographs. So what you read is not the truth. It is someone’s version of it. Always read with an open mind. Be a detective when you read! Ask questions, think, search for clues and weigh up the facts. Then decide for yourself which story comes closest to the truth. You must have learnt about Christopher Columbus at school. Well there’s another side to that story in our article called ‘Who discovered America?’. Read it and decide what YOU think really happened. Upbeat writes a lot about young peoples’ experiences of growing up. There’s another side to being a teenager - being the mother of one. Nomasondo Hadebe openly shares with us the pain and joy of having teenage children. We don’t only learn from grown-ups or famous people (or both). Upbeat is full of stories about youth, their ideas and feelings about the world. By sharing experiences, problems and ideas we can learn from each other. So don’t miss our letters page, advice column and talkshop. Read what young people have to say. You can agree or disagree with their ideas. And when you close the magazine you may feel a little sadder, happier or angrier. But you will always be wiser

- Description: In the tumultuous time we find ourselves, debates about pedagogy have taken centre stage once again. Concerns raised by the student protests of 2015 and 2016 have highlighted the urgent need to re-think traditional teaching, learning and assessment practices, as well as the development of decolonised and transformative curricula.Traditional notions of academic and professional development are now being tested and contested, insofar as they are able to respond to student challenges in appropriate, responsive, legitimate and relevant ways. As a professional organisation dedicated to supporting learning and teaching, the executive team of HELTASA responded to the challenge in this article by engaging with perspectives on the purpose, role and conceptualisation of academic development in the current decolonial moment in the South African Higher Education landscape. Critical processes that enable academics to engage, share thoughts and debate epistemological, pedagogical and methodological options to support students and academics are much needed. And the context and spirit in which these debates occur may be as important as the debates themselves.At its annual conference, the executive team facilitated a critical dialogue with conference delegates on the limitations and opportunities of AD in our current context. Given the diverse teaching and learning contexts and institutional differentiation in the sector, this article explores individual and collective theorised observations, reflections and experiences of the seven facilitators who led the CD. These reflections were analysed and discussed against the backdrop of AD as well as the affordances of CD as a participatory learning and engagement methodology. The findings showed that there is dire need to re-imagine, not only AD’s role but alternative forms of critical engagement in the sector.

- Description: Seasonality of reproduction in common dolphins (Delphinus delphis), bottlenosed dolphins (Tursiops aduncus), striped dolphins (Stenella coeruleoalba) and humpbacked dolphins (Sousa chinensis) was examined using standard light microscope techniques. In the males four stages of testicular development could be identified. Individuals less than 2.26m in length and 105kg in mass had testes that contained small seminiferous tubules (0.048mm ± O.Olmm in diameter) and were classified either as juveniles (gonocytes present) or inactive (no gonocytes). Adults whose testes contained spermatozoa were said to be in late spermatogenesis while those whose testes contained no spermatids or spermatozoa were referred to as being in early spermatogenesis. In the males of D. delphis, T. aduncus and S. chinensis, late spermatogenesis occurred throughout the year and there was no significant difference in the monthly mean seminiferous tubule diameters (p > 0.05) within species. I conclude therefore that in these three species spermatogenesis is aseasonal. No conclusions about seasonality of spermatogenesis could be made for S. coeruleoalba owing to the small sample size. Large Graafian follicles occurred in the ovaries of all four species in most months of the year. However, the presence of Graafian follicles can not be taken as an indication of timing of reproduction since they may be remnants of follicles that have not yet degenerated. In D. delphis, T. aduncus and S. coeruleoalba luteal bodies (corpora albicans or corpora lutea) occurred in most months of the year. Active corpora lutea will be present in all months, in some members of the population, since gestation is approximately 12 months. The sperm structure of D. delphis was examined by scanning electron microscopy. The sperm of D. delphis is essentially similar to that described for two other species of Cetacea (Physeter catodon and Tursiops aduncus), having an ellipsoidally shaped head and a short mid-piece with nine mitochondria. The sperm dimensions for D. delphis were head length, 4.4pm; head width, 2.0pm and mid-piece length, 2.4pm. An analysis of foetal age in D. delphis showed that the majority of the foetuses were conceived in January with birth occurring the following summer (December), suggesting that reproduction is seasonal. Neonates of T. aduncus were found throughout the year suggesting aseasonal reproduction. Foetal material was not available for S. coeruleoalba and S. chinensis. Seasonality of reproduction in the four species of dolphins studied has been discussed in relation to feeding, migration and worldwide distribution of the species.

- Description: Energy generated from non-renewable energy sources has a drawback of prompted outflow of ozone harming substances. These drawbacks of the non-renewable energy have quickened innovative work of renewable power sources, since they have an advantage of the provision of a better, preserved, decent environment that is free from natural contamination and commotion. Photovoltaic devices are prevalent in improving the green energy utilization and defeating the natural concerns yielded from the current most overwhelming energy sources. Herein, the synthesis, characterization, and application of Molybdenum chalcogenide nanoparticles (NP) as alternative sources in the absorber layer of quantum dot solar sensitized cells (QDSSCs) is discussed. The MoS2 NPs were synthesized from the aliphatic and aromatic dithiocarbamate (DTC) ligands and complexes as precursors. The successful synthesis of the DTC ligands and MoDTC complexes was confirmed through characterization with a variety of techniques including 1H and 13C-NMR, Raman Spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), Ultraviolet-visible spectroscopy (UV-VIS), Thermogravimetric analysis (TGA) and Derivative thermogravimetric (DTG) analysis. The synthesized MoDTC complexes (precursors) were further used in the synthesis of MoS2 nanoparticles. A bottom -up colloidal approach was employed for the synthesis of the MoX2 NPs. The successful synthesis of the NP was confirmed as the results from the diffractive peaks obtained from XRD which were positive and agreed in comparison with the standard. The diffractive peaks were shown in the planes (100), (002), (100) and (105) for MoS2 nanoparticles; (002), (100), (103) and (110) for MoSe2 and (0002), (0004), (103) as well as (0006) for the MoTe2 nanoparticles. The MoSe2 nanoparticles showed the least size of the nanoparticles followed by MoTe2 and lastly MoS2. These results agreed with the results obtained using SEM analysis. For the optical properties of the nanoparticles, UV-VIS and PL were used, the shift of the peaks from the red shift (600 nm) to the blue shift 270-5 nm and 287-9 nm (UV-VIS) confirmed that the nanoparticles were quantum confined. The application of the MoX2 NPs in QDSSCs was done with MoSe2 showing the greatest PCE of 7.86 percent followed by MoTe2 6.93 percent and lastly MoS2 with a PCE of 6.05 percent and 5.47 percent. , Thesis (MSc) (Chemistry) -- University of Fort Hare, 2021

- Description: [From Editorial] Four of the five articles in this issue either deal explicitly with or refer to the effects of the AIDS epidemics in the authors' countries. The fifth paper deals with late-life chronic diseases of life-style. In the first paper, Akinsola examines effects of the epidemic on older Batswana and evaluates the effectiveness of his country's Community Home-Based Care programme against the programme's objectives, with special reference to the situation of older persons as primary caregivers to PWAs and AIDS orphans. He concludes that the situation of older carers calls for strong and urgent policy action to assist this highly vulnerable and marginalized group in its critical and valuable role and function as carers. In her paper on the provision of housing and care for older persons in Zambia, Sichingabula considers implications of the anticipated increases in AIDS morbidity and mortality, in the form of an increased demand for formal housing and care by older Zambians in the face of diminished traditional support. Given effects of the country's Structural Adjustment Programme and the Zambian government's inability to expand provision of formal support for the older population, the author makes recommendations for initiatives which NGOs can undertake towards meeting the needs and improving the quality of life of older persons. Next, Shaibu examines the experiences of caregivers to older persons in Botswana within a context of pervasive, abject poverty and multiple, unmet basic needs. The author notes how the HIV I AIDS epidemic, in addition to other social forces, impacts family structures and the capacity of Batswana to care for older relatives. In their paper, authors Patel, Steyn, Charlton, Bourne, Laubscher, Fourie and Jooste describe the risk-factor profile for chronic diseases of life-style, such as hypertension, hypercholesterolaemia and obesity, in the older black population of Cape Town and compare it with risk profiles in other South African ethnic groups. The authors note that although the study population is still at low risk of cardiovascular disease - for example, demographic changes, including urbanisation and the adoption of urban life-styles, are likely to lead to an increase in chronic morbidity in future older cohorts in this population. In a second paper, Sichingabula assesses the physical and social environment of Divine Providence Home, a residential care facility for destitute older persons in Lusaka, Zambia. She draws practitioners' attention to the prudence of incorporating design features in facilities built for older persons which enhance the users' mobility, independence and quality of life. She also highlights a lack of social stimulation and the inactivity of the residents at the home. The author makes the point that given an anticipated increased demand for admission to residential care facilities as a result of AIDS-related deaths and loss of traditional support for older persons, living environments in these facilities must be optimized. In sum, the AIDS-related research papers in this number highlight a need to identify and to strengthen social and care systems which can assist older persons in Africa, as traditional systems are increasingly affected by demographic forces, particularly the effects of the HIV/AIDS epidemics. Finally, Moller reviews a recent, landmark Help Age International report (1999), which is a compilation of 15 papers on ageing in developing countries and challenges facing research, policy and practice.

- Description: The purpose of this study is to investigate challenges facing Small, Medium and Micro Enterprises (SMMEs) in order to improve the participation of SMMEs in public procurement processes within category B municipalities. A Total Quality Management approach was used to interpret the manner in which to install change within a selection of supplier procedures. The study employed desktop analysis to explain and describe the challenges SMMEs are facing in public procurement in the Sundays River Valley Municipality. Based on the discussions of the participation of SMMEs in public procurement, the challenges which exist within a centralised approach of public procurement were discovered. The findings of the study revealed that SMMEs are challenged by the lack of entrepreneurial coaching by local government, low demand for the commodities, lack of experience, skills and knowledge, limited access to debt finance, poor marketing skills, poor managerial and lack of planning skills, gaps in implementation of preference point system, poor management of core strategies of the preferential system, gaps in implementation of preference point system, poor management of the tender system, improper integration of central supplier database, globalisation and the impact of e-procurement on local government level. Subsequently, the study made recommendations in this regard.

- Description: Child sex tourism is tourism organised with the primary purpose of facilitating a commercial sexual relationship with a child. It involves a segment of the local child sex industry that is directly connected to both an international and domestic tourist market. The increase of tourism has brought with it complications in that tourism is being used as a means for sex tourists to initiate contact with children. Aside from child sex tourists who are paedophiles, there are those who engage in the opportunistic exploitation of children while travelling on business or for other reasons. There are a number of social and economic factors leading to child sex tourism and the effect is that child victims are exposed to immediate harm, irreversible damage and even death. As South Africa's tourism industry expands into one of the country’s top earners of foreign currency, it is unfortunate to note that its child sex tourist trade is also on the increase. Reports show that sex tours are as easily organised as wine route tours in Cape Town. Commercial sexual exploitation of children is prevalent in South Africa and has become more organised in recent years. A comprehensive response to the problem is essential to ensure that South Africa does not become a “safe haven” for child sex tourists. Effective laws at home and the extraterritorial application of these laws to prosecute South African nationals for crimes committed abroad are imperative. Significant steps are being taken both nationally and internationally to target child sex tourism. South Africa has ratified several international instruments on children’s rights, trafficking in persons, child labour, and discrimination against women and young girls, all of which relate to child sex tourism. In doing so, South Africa has made an international commitment to uphold the provisions of these instruments and give effect to them. South Africa is therefore under an international obligation to create the necessary structures and apply mechanisms and resources to combat child sex tourism.

- Description: The world’s population is growing at an average of 1.2 percent per annum and forecasts see the global population reaching 9.6 billion by 2050. This places great demands on the sustained production capacity of agricultural organisations to meet the desperate need for nutrition. This problem will continue to persist if production methods do not evolve to improve production and quality. Hydroponics and Controlled Environment Agriculture (CEA) was first seen in Rome during the 1st Century. Then sixteen Centuries later Greenhouses were developed in France and England as experimental hydroponics for basic laboratory research. Rapid expansion took place from about the 1950’s in areas where traditional openenvironment agriculture was difficult or impossible such as the deserts of Iran, Abu Dhabi and California. Sixty-five years later in 2015 hydroponics and CEA are well established around the world with thousands of hectares under propagation. Hydroponics is a method of agricultural production that has been refined over the years to become an exact science. Through the application of technology and know-how the physiological processes within plants can be manipulated and controlled to produce superior results. These results require less land area and less water to accomplish. It can be seen, based on this development, that hydroponics is such an evolution that has the capacity to meet the needs of a growing global population and its nutritional needs. The challenge lies, though, in the scientific understanding and application of knowledge in growing and managing a hydroponics farm. This study seeks to determine the internal data and external information needs of farmers in the hydroponics industry. This data and information will be integrated into a Farm Management Information System (FMIS) model that will be used for decision making, report generation and documentation. The problem leading to this study is the dissemination of data and information sources that are currently underutilised and difficult to access. In determining the internal data and external information needs, an empirical study was conducted using structured interview. Thirty farm managers were interviewed to assess what their current information system consisted of, whether they had a need for an FMIS and what internal data and external information was needed which related to four functional components of hydroponic farming. The results of this study indicate that there is a need for an FMIS for the hydroponic industry in South Africa. The results also indicate that managers are not fully satisfied with the performance of their current information system and would be interested in considering alternative information systems. Data points relating to the four functional components were assessed and integrated into an FMIS model for the hydroponic industry. This model sets out to integrate internal data and external information for purposes of decision making, report generation and documentation.

- Description: Construction management competencies are essential to realise sound practices among and to realise optimum performance by, inter alia, emerging civil engineering contractors. Such competencies enable a clear focus on the business of construction and the management of projects, with increased efficiency and reduced costs as a benefit. The objective of the MSc (Built Environment) treatise study were to determine the current practices and performance of emerging civil engineering construction contractors operating in the Nelson Mandela Bay Metropole. The descriptive method was adopted in the empirical study. The salient findings of the study are: most of the emerging civil engineering construction contracting organisations lack construction management competencies; construction resources are inappropriately managed leading to construction failures; most of the emerging civil engineering construction contracting organisations lack adequate supervision resulting to poor workmanship; there is a shortage of skilled labour amongst emerging civil engineering construction contractors; procurement processes are inappropriate leading to under capacitated emerging civil engineering construction contracting organisations being awarded contracts; most emerging civil engineering construction contracting organisations lack the requisite aptitude for construction; there is a lack of capacity at all management levels of emerging civil engineering construction organisations in managing the business of construction and that of projects; the nine functions of organisations are not comprehensively represented, and self-ratings indicate inadequacy relative to the management function of control, and relative to certain activities of the organising function. Conclusions include that emerging civil engineering construction contracting organisations need to be comprised of technical teams that possess adequate competencies and that use the construction technology to its full use enabling their organisations to stay abreast of their competitors. Recommendations that can contribute towards improving the status quo include: formal civil engineering and construction management education, resources must be present and training should be promoted throughout the industry at all levels of management to ensure proper supervision and correct use of adequately trained labour, skilled or semi-skilled, incapacitated emerging civil engineering construction contractors should be awarded contracts through appropriately and structured procurement procedures, adequate aptitude in construction should be promoted and enhanced in order to realise conceptualisation and visualisation capabilities, comply with legislation, maintain records and communicate using state of the art technology, optimally manage the finances, have the requisite resources and undertake the work efficiently, interact with the respective publics, and market the organisation to ensure sustainability thereof.

The interaction of children's rights, education rights and freedom of religion in South African schools

- Description: This study examines the topic of the interaction of children’s rights, education rights and freedom of religion in South African schools from a legal perspective. It comprises of a discussion on the historical development of religion in South African schools; South Africa’s international obligations with regards to children’s rights, education rights and freedom of religion and the South African substantive law pertaining to children rights, education and freedom of religion as impacting on legal issues pertaining to religion in schools. The study utilises a desktop approach, which comprises of a wide range of legal and other literary sources, international instruments, statutes and case law on children’s rights, education rights and freedom of religion. Importantly, it highlights the integral connection between these aforementioned rights when dealing with issues pertaining to religion in schools. This thesis illustrates that much of the historical development of religion in schools took place without consideration of children’s rights, or more particularly, the best interests of the learners. Instead, (a particular brand of) religious beliefs were promoted in education above other religions and the well-being of school-children. Furthermore, despite the introduction of specific children’s rights into the Constitution, this thesis emphasises that the rights of children have still not been recognised sufficiently in education laws and policies. It is submitted that children’s rights have a paramount and practical role to play in matters pertaining to religion in South African schools. Consequently, it is recommended that children’s rights, more particularly the best interests of the child principle, should be expressly introduced into education legislation and policies. This will create legal obligations for school administrators and SGBs on the inclusion of children’s rights in religious exemption procedures. Furthermore, it is recommended that national guidelines on religious/cultural exemptions (which incorporate children’s rights) be developed which will set legal parameters for the handling of religious/cultural exemption procedures in schools. This thesis also argues against the interpretation that the right to establish private schools includes the right to require religious conformity from non-adherent learners by way of a complete waiver of their religious freedom. Despite the importance of respecting the right of religious communities to protect and preserve their faith in private schools, it is submitted that this right cannot be exercised without regard for the religious freedom, dignity and best interests of non-adherent children. As a result, it is submitted that the waiver of the freedom of religion of non-adherent children is not consistent with the values which South African society reveres and therefore cannot be enforced. This thesis suggests that there is a way for the rights of private schools and the rights of non-adherent children to co-exist in harmony through the application of the reasonable accommodation principle in private schools. Reasonable accommodation of different faiths teaches religious tolerance to leaners in private schools and ensures that they are prepared to grapple with the religious diversity that they will inevitably face outside of the school environment. It is submitted that the enforcement of reasonable accommodation in private schools is to the benefit of all learners in private schools and to South African society in general. Moreover, this study questions and analyses the state’s provision of compulsory religion education in public schools through the National Policy on Religion and Education. A theoretical distinction is made between religion education and religious instruction in the National Policy itself. Religious instruction refers to the teaching of specific religious beliefs. Religion education refers to the teaching about different religions and worldviews from an academic perspective. It is submitted that the National Policy is correct in removing religious instruction from public schools as this would not be in accordance with freedom of religion or equality rights of learners who are not of the majority faith. It is submitted further that, although the provision of compulsory religion education in public schools impacts upon the freedom of religion of learners and their parents, (if taught correctly) it is a reasonable and justifiable limitation on freedom of religion in that it pursues the legitimate state goal of nation-building through the teaching of religious tolerance and “celebrating diversity” in schools. In light of South Africa’s history of religious discrimination, it must be recognised that the current position (although not problem- free) is a significant step forward in the protection of minority religious rights in South African schools. Despite this, it is submitted that there are numerous problems with the implementation of the National Policy that impact upon the dignity, equality and other rights of the learners concerned. These problems cannot be ignored since they impact upon the daily lives of school children. However, many of these problems can be minimised through more effective teacher training in this subject area. Accordingly, this thesis recommends that the current position be maintained as an acceptable compromise between the two extremes of providing religious instruction in one faith and removing religion education from public schools altogether. However, it emphasises that the state has to make a concerted effort to improve teacher training in this subject area in order to ensure that the objectives of the National Policy are carried out as envisaged. Furthermore, this thesis finds that certain provisions of the National Policy contain not only educational goals, but spiritual goals. Also in some instances, it is difficult to determine whether the religion education curriculum borders on being religious or not. In accordance with freedom of religion, it is submitted that the line between religion education and religious instruction must be clearly drawn in law and in practice. Consequently, the state must reconsider the National Policy and the corresponding religion education curriculum to ensure that they are aligned with the objectives of nation-building in all respects, meaning that any provisions or learning outcomes which have purely spiritual goals- must be amended or removed.

- Description: Human trafficking is a social problem that has left no state or country immune to its effects. Literature indicates that human trafficking causes economic social and physical disruptions. Families are left broken and communities divided and children left homeless. Its victims are mostly women and children who come from low socio-economic status. Studies have been conducted on the roles of Non-Governmental Organisation`s across the globe but reports on the roles of NGOs in the Eastern Cape are unknown. This study reports on the roles of Non-Governmental Organisation`s (caregivers) in the Eastern Cape. This investigation is an exploratory qualitative study. A purposeful sampling strategy was used to recruit the Non-governmental organization (caregivers). In depth open ended interviews were conducted. The theories of Interpretative Phenomenological Analysis (IPA) and socio-ecological theory were used to discuss the findings of the study. The findings of the study were categorized into four main themes including; knowledge of human trafficking, causes of human trafficking, roles of non-governmental organization (caregivers) in the Eastern Cape and strategies available in the Eastern Cape Province. The findings showed that human trafficking is present in the Eastern Cape. Abused and neglected children are more likely to become potential victims of human trafficking. The caregivers play a huge vital role in the fight against human trafficking. Lastly, the strategies implemented are not as effective as they would have been if adequate legislation was passed against human trafficking.

- Description: To support current and emerging database applications, Object-Relational Database Management Systems (ORDBMS) provide mechanisms to extend the data storage capabilities and the functionality of the database with application-specific types and methods. Using these mechanisms, the database may contain user-defined data types, large objects (LOBs), external procedures, extensible indexing, query optimisation techniques and other features that are treated in the same way as built-in database features . The many extensibility options provided by the ORDBMS, however, raise several implementation challenges that are not always obvious. This thesis examines a few of the key challenges that arise when extending Oracle database with new functionality. To realise the potential of extensibility in Oracle, the thesis used the problem area of image retrieval as the main test domain. Current research efforts in image retrieval are lagging behind the required retrieval, but are continuously improving. As better retrieval techniques become available, it is important that they are integrated into the available database systems to facilitate improved retrieval. The thesis also reports on the practical experiences gained from integrating an extensible indexing scenario. Sample scenarios are integrated in Oracle9i database using the data cartridge mechanism, which allows Oracle database functionality to be extended with new functional components. The integration demonstrates how additional functionality may be effectively applied to both general and specialised domains in the database. It also reveals alternative design options that allow data cartridge developers, most of who are not database server experts, to extend the database. The thesis is concluded with some of the key observations and options that designers must consider when extending the database with new functionality. The main challenges for developers are the learning curve required to understand the data cartridge framework and the ability to adapt already developed code within the constraints of the data cartridge using the provided extensibility APls. Maximum reusability relies on making good choices for the basic functions, out of which specialised functions can be built. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: It is estimated that 6742 South African women are diagnosed with cervical cancer and 3681 women die from the disease every year. In 1993, The Centers for Disease Control declared cervical cancer an Acquired Immunodeficiency Syndrome defining illness. Apart from persistent human papillomavirus infection, HIV infection is the most common co-factor contributing to cervical cancer in South Africa. Studies have noted that in HIV positive women, there has been an occurrence of faster progression to more advanced stages of cervical cancer with high cases of treatment failure and recurrence. There is limited literature available regarding the prognosis of HIV positive women who suffer from cervical cancer. Women who are HIV positive and have cervical cancer have not been evaluated in detail regarding their response and adherence to cervical cancer treatment. Standard treatment protocols for this set of patients have not been defined. The aim of this study was to assess how HIV positive women who have been diagnosed with cervical cancer responded and adhered to cervical cancer therapy which includes: curative radiotherapy; curative chemotherapy; concurrent chemoradiation or palliative radiotherapy. The study also evaluated the effects of the concurrent use of antiretrovirals and cervical cancer treatment. This was done to determine whether invasive cervical cancer in women who were HIV positive could be managed using the same treatment protocols as patients who were HIV negative. A historical cohort design was employed for the study. The study was conducted at the Oncology Department of a tertiary level hospital located in the Eastern Cape Province, South Africa. The total sample consisted of 196 medical records of women diagnosed with cervical cancer between 2005 and 2008. One hundred women were HIV negative, 83 were HIV positive and the HIV status of 13 women could not be determined. The records were audited over a period of two years from the date of diagnosis. The term „complete response‟ referred to patients who had no recurrence of cervical cancer and no evidence of metastases after undergoing treatment. At one month following treatment there was a significant difference in the incidence of complete response between the HIV positive patients and the HIV negative patients (Chi2 = 16.4, d.f. = 1, p = 0.00005, Cramer‟s V = 0.31). The significant difference in response to treatment between the HIV positive patients and the HIV negative patients was maintained at six months after treatment (Chi2 = 15, d.f. = 1, p = 0.00011, Cramer‟s V = 0.34), 12 months after treatment (Chi2 = 20.5, d.f. = 1, p = 0.00001, Cramer‟s V = 0.37), 18 months after treatment (Chi2 = 9.8, d.f. = 1, p = 0.00173, Cramer‟s V = 0.28) and 24 months after treatment (Chi2 = 5.0, d.f. = 1, p = 0.02571, Cramer‟s V = 0.26). At each of these intervals, cases of treatment failure and metastases were significantly higher in the HIV positive women than in the HIV negative women. Although there was no significant difference in the incidence of adherence between the HIV negative women, the HIV positive women who were on HAART and the HIV positive women who were not on HAART, there was a significant difference in the incidence of the various reasons for non adherence between the various groups. These reasons included: missed scheduled appointments (Chi2 = 2.9, d.f. = 2, p = 0.02385, Cramer‟s V = 0.31); low blood count (Chi2 = 4.0, d.f. = 2, p = 0.01327, Cramer‟s V = 0.15); radiotherapy induced skin breakdown (Chi2 = 0.6, d.f. = 2, p = 0.04581, Cramer‟s V = 0.16) and radiotherapy induced diarrhoea (Chi2 = 6.9, d.f. = 2, p = 0.03118, Cramer‟s V = 0.19). According to the 2004 National Antiretroviral Treatment Guidelines, cervical cancer patients would fall into the WHO stage IV category of HIV disease thus all patients with confirmed diagnosis of invasive cervical cancer should be commenced on antiretrovirals as soon as the cancer diagnosis is made regardless of their CD4 count. However, in the current study, 13 percent (n= 83) of the HIV positive women were not on antiretrovirals. The study concluded that HIV positive women had a higher incidence of both treatment failure and metastases to cervical cancer treatment. Standard radiotherapy and concurrent chemoradiation cervical cancer treatment protocols should be still be used in both HIV negative patients and HIV positive patients so as not to compromise tumour control. Furthermore, in accordance with the antiretroviral treatment guidelines, all HIV positive patients with cervical cancer should receive antiretrovirals irrespective of their CD4 count.

- Description: Almost three decades after the official end of the apartheid, South Africa has been on a sturdy path that is characterised by deepening spatial economic inequalities. A plethora of policy instruments unleashed since 1994 had not only failed to stem the tide of poverty and inequality, but had deepened them. As part of this, South Africa’s most ambitious social engineering programme – land reform -- had disappointing outcomes. Premised on a view that these apartheid continuities were embedded in South Africa’s land administration system – which was incoherent and fragmented and requiring a systemic overhaul -- the study sought to explore the potential role of Open Government Data (OGD) in the repurposing of land administration system in the post-apartheid South Africa. To achieve this goal, the study was guided by the following objectives: to explore the ontology and the state of land governance and administration in the context of the post-apartheid South Africa; to undertake an evaluation or assessment of South Africa’s land data ecosystem; and to explore the potential role of OGD in the repurposing of land administration system in the postapartheid of South Africa. This study was steeped in qualitative research methods, underpinned by primary and secondary literature review. While the study was primarily pitched on a national scale – the combination of the systems and multiple scales approaches – yielded results which dislodges solutions that are required outside of the domain of a single state. This is one glaring example of land governance complexities that straddle beyond national scale – specifically in respect of new policy trajectories on trans-national boundaries and governance of water resources. Based on the holistic ontology of land, this study concludes that land administration and land governance overarching conceptual orientation -- concerned with land use decisions made by humans at various scales from a praxis and policy perspective –constitute two sides of the same coin, the former steeped towards practice and the latter steeped towards policy. Drawing from decolonial theories the study concludes that land does not only have multiple dimensions, but it also has multiple meanings, in a manner that calls for an ontological shift away from the western ontology, towards an inclusive and holistic conceptualisation. Historiography that is anchored in de-colonial thinking of South Africa’s land governance helps us understand how and why – colonial/apartheid norms acrimoniously found their way into the post-apartheid order -- the post-apartheid institutions of modernity rest on the same hierarchies of identities, classification and pathologisation. The study concludes that, while the colonial/apartheid administration may be gone, it’s underlying power matrices continue -- i.e. capitalism/European/patriachal/white – in a manner which explains the continuities of South Africa’s spatial inequalities and the associated economic inequalities. The organising principle for land relations (including opportunities) continues to be underpinned by gender, race and class, in ways that expose the mythical dimensions of the 'post-apartheid' underbelly. While identifying the need for homogenisation and rationalistion of colonial, apartheid and post-apartheid institutions (on a national scale) that is insufficient for the transformation of the colonial situation of what is in essence a part of the global system, the study advocates for the ‘repurposing of land governance and administration’ – underpinned by de-colonial thinking. Repurposing is seen as political imaginary that would entail uncoupling thought processes and praxis from the colonial matrices of power. The study goes on to conclude that there is a definite role for Open Government Data in repurposing of land administration in the post-apartheid South Africa – as a necessary, though in and of it’s own it is an insufficient condition to achieve that ideal -- but presents an opportunity to enhance transdisciplinarity approaches and efficiencies in internal government functioning and evidence-based decision making and policy formulation processes. , Thesis (PhD) -- Faculty of Science, Geography, 2021

- Description: Pressures from environmental agencies contribute to the challenges associated with the disposal of waste tyres, particularly in South Africa. Recycling of waste tyres in South Africa is in its infancy resulting in the historically undocumented and uncontrolled existence of waste tyre stockpiles across the country. The remote and distant locations of such stockpiles typically complicate the logistics associated with the collection, transport and storage of waste tyres prior to entering the recycling process. In order to optimize the logistics associated with the collection of waste tyres from stockpiles, useful information about such stockpiles would include estimates of the types of tyres as well as the quantity of specific tyre types found in particular stockpiles. This research proposes the use of computer vision for categorizing individual tyres and estimating the number of visible tyres in tyre stockpile images to support the logistics in tyre recycling efforts. The study begins with a broad review of image processing and computer vision algorithms for categorization and counting objects in images. The bag of visual words (BoVW) model for categorization is tested on two small data sets of tread tyre images using a random sub-sampling holdout method. The categorization results are evaluated using performance metrics for multiclass classifiers, namely the average accuracy, precision, and recall. The results indicated that corner-based local feature detectors combined with speeded up robust features (SURF) descriptors in a BoVW model provide moderately accurate categorization of tyres based on tread images. Two feature extraction methods for extracting features for use in training neural networks (NNs) for tyre count estimations in tyre stockpiles are proposed. The two feature extraction methods are used to describe images in terms of feature vectors that can be used as input for NNs. The first feature extraction method uses the BoVW model with histograms of oriented gradients (HOG) features collected from overlapping sub-images to create a visual vocabulary and describe the images in terms of their visual word occurrence histogram. The second feature extraction method uses the image gradient magnitude, gradient orientation, and edge orientations of edges detected using the Canny edge detector. A concatenated histogram is constructed from individual histograms of gradient orientations and gradient magnitude. The histograms are then used to train NNs using backpropogation to approximate functions from the feature vectors describing the images to scalar count estimations. The accuracy of visible object count predictions are evaluated using NN evaluation techniques to determine the accuracy of predictions and the generalization ability of the fit model. The count estimation experiments using the two feature extraction methods for input to NNs showed that fairly accurate count estimations can be obtained and that the fit model could generalize fairly well to unseen images.
