Description: Parasuicide is a problem that affects the youth locally and globally. Parasuicide has negative psychological impacts on youth. This study was designed to assess elements of parasuicide in the Buffalo City Metropolitan Municipality of South Africa, using records of patients admitted to Frere and Cecilia Makiwane hospitals between 2016 and 2020. The purpose of the study was to conduct a descriptive retrospective review of parasuicide among youth to determine trends, causes, and contributing factors of committing parasuicide. Methods A retrospective, quantitative and descriptive study was conducted with 200 files of patients aged between 18 and 35 years conveniently sampled. These patients diagnosed as committed parasuicide and were admitted at Frere and Cecilia Makiwane hospitals over a period of four years from 1 April 2016 to 31 March 202. Only record files of patients’ residing in East London and Mdantsane catchment area were selected. Raw data was collected for a period of twelve weeks using a developed data collection tool developed in Ms Excel spreadsheet. Results In this sample, the large number of the patients were under 26 years (60.5%), female (57%), single (92.5%), and Black (99.5%). Furthermore, majority of the patients had attained secondary education (89.5%), were unemployed (83%) and living with their families (59%). There were different methods and agents used by participants to commit parasuicide and reasons differed from person to person. Among patients who reported a suicide attempt, organophosphates were most commonly used agent for self-poisoning (47%, n=94), followed by substances such as use of drugs and alcohol (n=57, 28.5%), violence (n=27, 13.5%), corrosive agents including bleach and Jik (n=11, 5.5%), and hydrogen peroxide including acidic sub-stances like battery acid (n=11, 5.5%). The common reason found in the study and indicates participants had psychiatric disorder (34.5%). Conclusion Limiting access to organophosphate agents and other lethal means is an effective strategy that should be adopted to prevent parasuicide among youth. Timely identification of risks or warning signs, social prevention and immediate intervention at the state level will play an important role in controlling parasuicide among youth. Moreover, improving health care services with psychotherapy support would empower youth with skills that would enhance their self-confidence, self-worth and resilience. Consequently, attainment of these attributes would result in the prevention and control of parasuicide amongst youth. , Thesis (MPH) -- Faculty of Health Sciences, 2021

Description: Size-fractionated chlorophyll-a (chl-a) concentrations and the in situ grazing rates of the copepods, Pseudodiaptomus hessei and Acartia longipatella, were assessed seasonally at the temporarily open/closed Kasouga estuary situated along the southeast coast of southern Africa. Total integrated chl-a concentration ranged between 1.17 and 12.18 mg chl-a m^(–3) and was always dominated by small phytoplankton cells (<20 μm), which comprised up to 86% (range 64–86%) of the total pigment. Total zooplankton abundance ranged between 2676 and 62 043 individuals m^(–3). These copepods numerically dominated the zooplankton counts, accounting for between 79% and 91% of the total. Gut pigment concentrations of the two species at night were significantly higher than the daytime values (P<0.05 in all cases). The observed pattern could be related to the marked diurnal vertical migration patterns exhibited by the copepods. Gut evacuation rates of P. hessei during the study ranged between 0.29 and 0.77 h^(–1) and between 0.39 and 0.58 h^(–1) for A. longipatella. The rate of gut pigment destruction for P. hessei and A. longipatella ranged between 55% and 81% and between 88% and 92% of the total chl-a ingested, respectively. The combined grazing impact of the two copepods ranged between 0.65 and 4.37 mg chl-a m^(–3), or between 4.3% and 35.9% of the available chl-a in the water column. Variations in the grazing activity of the two species could be attributed largely to seasonality in water temperature and shifts in the phytoplankton community structure and zooplankton abundance.

Description: The Third Biennial Congress of the South African Democratic Teachers Union (Sadtu) is one of the most important national events in the short but eventful history of this giant teacher union. This Congress takes place against the backround of unprecedented political transformation which was ushered in by the dawn of a new democracy in April 1994. History will proudly record Sadtu as one of those pioneering allies who fought resiliently to liberate the masses of our people and to eradicate Apartheid education and all its vestiges. This Congress, scheduled to be convened during the period 11-13 July 1995, will be graced by the presence of more that 700 accredited Sadtu delegates, 100 national observers and 20 international guests. This, in fact, will be the largest assembly of delegates at a Sadtu Congress since inception. Since its inception in 1990 Sadtu has been steadfast and persistent in its resolve to transform the education system in our country. The early 1990’s were an era of heightened levels of teacher consciousness which highlighted the plight of the South African teacher. It was during this period and thereafter that thousands of teachers swelled the ranks of Sadtu as it was viewed as a champion of teacher rights and an ideal vehicle for transformative changes as espoused by the teacher at the grassroots level. This significant shift of membership from established teacher associations disturbed the balance of power in the education terrain. In grasping the strategic initiative Sadtu was able to earn an enviable position in educational struggles.

The Fishes of Zimbabwe and their Biology

Description: The first comprehensive book on the fishes of Zimbabwe appeared in 1961 and was written by Rex Jubb. He followed it with a major treatise on the fishes of southern Africa published in 1967. These books were published at a time when interest in fishes – partly stimulated by the creation of Lake Kariba –was growing, and they were welcomed by anglers and scientists alike. Zimbabwean ichthyology progressed rapidly during the years following their publication and knowledge about our fishes grew steadily. New insights and understanding of their systematics led to numerous taxonomic revisions, bringing with them inevitable changes to their scientific names. At the same time increased collecting meant that new species were being added to the Zimbabwean list. By the early 1970s Jubb’s books had become outdated and there was a clear need for a new volume on the fishes of this country. The National Museums and Monuments met this need by publishing Graham Bell-Cross’ The Fishes of Rhodesia in 1976. This book was available at a remarkably low price and such was its popularity that it was soon out of print. It rapidly became outdated as well and was revised by John Minshull as the Fishes of Zimbabwe, published in 1988. This version had a number of new features such as the inclusion of exotic species and species discovered in the country since 1976, as well as name changes brought about by new developments in taxonomy. It, too, was available at a very low price and has proved to be very popular; the demand was so great that it was reprinted without alteration in the 1990s. By this time, however, it had also become outdated and there was a need for yet another revision, or for a completely new type of book. I have chosen the latter option in preparing this book, since there seemed little point in attempting to revise the earlier ones within their original format. I felt that it would not be desirable to produce another field guide type of book that would have to compete with Paul Skelton’s superb volume, A Complete Guide to the Freshwater Fishes of Southern Africa, first published in 1993, with a second edition eight years later. Instead, I decided that I should try to summarise the existing data about fishes in Zimbabwe. My dealings with students and inexperienced fish biologists has made it clear that many of them do not know what work has been done, or not done, on Zimbabwe’s fishes and they are not familiar with the literature. Much of it is, in any case, to be found in obscure publications that are not readily available in Zimbabwean libraries, which have declined in recent years and no longer subscribe to major international journals or even to local ones. This makes it very difficult to keep up with information or to track it down. I am aware, of course, that such a book will never be complete and may already be outdated at the time of its publication, but I hope that it will supply the basic background information for anyone interested in Zimbabwean fishes and provide a platform from which further studies can be launched. Wherever possible, I have used only data from Zimbabwe, although there may be an extensive literature from other countries for widespread or economically important species, such as Clarias gariepinus or Oreochromis mossambicus. This was a conscious decision because I wanted to summarise what is known about the fish in this country, so that other workers can assess what still needs to be done. Nevertheless, I have used some data from outside Zimbabwe, especially for fish from the upper Zambezi because of its relevance to our situation. As far as possible I have tried to use only published works as references, with the exception of university theses and some institutional reports, since most unpublished work is generally difficult to locate and ephemeral. The scientific names of fishes often change as systematic knowledge advances and the reader will note that there have been many changes since Bell-Cross & Minshull (1988) was published. Common names are a problem because of local variations and anglers in particular have various names (or nicknames) for popular angling species; I have used the standard names with these other names included in brackets where necessary.

Description: The harvesting of non-timber forest products (NTFPs) is a global phenomenon, the sustainability of which has been studied for many species at the individual and population level. However, the broader scale impacts of NTFP harvesting have been acknowledged but rarely examined. We assessed plant size and the soil attributes undercanopy and in the open, in replicate, paired harvested and non-harvested sites for three NTFPs differing in the extent of biomass removed, i.e. timber for firewood from a tree (Acacia karroo), fruits from a cactus (Opunita ficus-indica) and flowering culms from a grass (Cymbopogon marginatus). Soil variables tested included pH, resistivity, P, total N, nitrate nitrogen, ammonium nitrogen, K, Na, Ca and Mg. The extent of loss of soil nutrients decreased across the three NTFPs relative to the proportion of biomass removed. Thus, significant differences in more soil variables were evident for the firewood species, least for the fruit species and intermediate for the grass species. Lower soil pH, P, C and K were evident in soils collected underneath A. karroo, while losses in cations of Na, Ca and Mg were reported in soils underneath C. marginatus, and only NO3N losses were recorded underneath O. ficus-indica. Our study reveals that while non-timber forest product (NTFP) harvesting may affect soil nutrients, this is not uniform between species and is likely to be a function of the extent of biomass removed and harvesting frequency. This indicates the need for caution in generalisations about the ecosystem-level impacts of NTFP harvesting as well as a concerted effort to better understand impacts at a greater range of scales than has been the case to date.

Description: Alcohol use during pregnancy is known to cause neurodevelopmental disorders in offspring, known as Fetal Alcohol Spectrum Disorders (FASD). High prevalence of FASD has been observed in certain parts South Africa, but many areas of the country remain unstudied, and factors contributing to drinking among pregnant women are poorly understood. This study surveyed 1099 women attending antenatal care at public primary healthcare facilities in the Buffalo City Metropolitan Area in the Eastern Cape. Data was collected using the Alcohol Use Identification Test, a 10-item self-report measure of drinking behaviour in isiXhosa, English, and Afrikaans. Factors associated with alcohol use, risky drinking, binge drinking, and hazardous/harmful drinking were identified using logistic regression. A minority of the sample reported alcohol use (64%). Among those reporting alcohol use, most reported occasional binge drinking (63%) and met criteria for risky drinking (59%) and hazardous/harmful drinking (52%). Living with a regular drinker was significantly associated with alcohol use (OR 1.98, 95% CI 1.51 – 2.58), risky drinking (OR 2.03, 95% CI 1.49 – 2.76), binge drinking (OR 2.21, 95% CI 1.64 – 2.97), and hazardous/harmful drinking (OR 2.0, 95% CI 1.41 – 2.99). However, women who were married/cohabiting were less likely to report alcohol use (OR .71, 95% CI .53 - .95). Experiencing intimate partner violence during the current pregnancy was associated with alcohol use (OR 2.42, 95% CI 1.38 – 4.27) and hazardous/harmful drinking (OR 2.62, 95% CI 1.32 – 5.22). In this study, women who identified as Coloured were more likely to report alcohol use than Women who identified as African (OR 2.74, 95% CI 1.4 – 5.36). These findings simultaneously provide evidence of problematic drinking among pregnant women in a previously understudied area and show that external factors affect women’s drinking behaviour during pregnancy. Interventions aimed at reducing the incidence of FASD should consider alcohol use by pregnant women in the context of their lived experiences. , Thesis (MA) -- Faculty of Humanities, Psychology, 2022

Description: Drawing on Bourdieu’s theories of field and capital, we examine the limitations that a journalism school at a prestigious university faces in making a meaningful contribution to the field within a developing country. In the postapartheid South African media landscape, journalism is under pressure both from global forces and a political imperative to address social justice. Given the heterogeneity of the journalistic field and the fact that what counts as capital in it is contested, the School of Journalism and Media Studies at Rhodes University attempts to redefine the parameters by inculcating a particular approach to and philosophy of journalism practice. While Rhodes wants to educate excellent (professional) journalists, it is guided by an overt political mission to cultivate a journalism that is not necessarily ‘in sync’ with the wider field. Ironically, most undergraduates come from the economic and cultural elite, with specific intentions to accumulate the capital which Rhodes bestows. Students are confronted with their privilege and with alternative ideas about the purpose of journalism, and are asked to make choices and take up positions. We consider whether this critical praxis approach is able to influence the ‘state of play’ – or the distribution of power – within the field.

Description: Successful development projects are not only grounded in proper planning and implementation but also in evaluation. Numerous development projects are implemented successfully but lack evaluation. This study evaluates the Joint Action Project (JAP) waste intervention that took place in Gqeberha Township in February 2020. The intervention was designed and implemented by a group of student volunteers from Nelson Mandela University (NMU), Port Elizabeth (PE) College and Wismar University. This was a collaborative project between Development Studies, Human Settlements Development, Electrical Engineering, Communication and Design as well as Architecture students who worked together to construct a workspace for a male informal waste picker residing in Gqeberha township. The study adopted a qualitative research approach and data was collected through interviews and field observation. Although the findings of this study revealed that there were some challenges encountered by the beneficiary and the JAP team during the project implementation, the benefits of the intervention exceeded these challenges. These benefits include the improvement of the beneficiary’s livelihood and waste picking business, improvement of health and improvement of the environment surrounding the intervention site , Thesis (MADS) -- Faculty of Business and Economic Sciences, 2021

Description: The globally increasing number of individuals suffering from Type 2 Diabetes Mellitus (T2DM), a completely preventable incurable disease of the pancreas, highlights the need for an effective tool for users to understand the relationship between their behaviours and the effect that those behaviours can have on their blood glucose levels (BGLs). There are few Information Visualisation (IV) tools available that can be used to reduce the cognition required to understand correlations between behaviour and BGLs. Existing tools require time-consuming, lengthy inputs and provide simple visualisations that do not show correlations. This leads to ineffective self-management of T2DM. Information Visualisation (IV) techniques can be used to support effective self-management of T2DM and reduce the cognition required to interpret DM data. Suitable IV techniques were identified and used to visualize T2DM data to aid in the self-management of the disease. Temporal charts, i.e. The Bar, Pie and Line Chart as well as heat maps, were selected as the most appropriate IV techniques to visualize T2DM data as they support time-series data well. A prototype, MedicMetric was created as an IV tool for visualizing T2DM data. MedicMetric incorporated three designed charts, namely the Change Rate Line View, the Radial Progress View, and the Annotated Line View. The Change Rate Line View and Annotated Line View both used line IV techniques, while the Radial Progress View made use of the bar IV technique. The Change Rate Line View performed the worst overall. A usability evaluation was conducted to compare these techniques and to determine which technique is most suitable for visualizing T2DM data. The results leaned significantly in favour of the Annotated Line View. This view is most similar to the line charts typically used in other IV tools. For this reason, the MedicMetric app was briefly compared to the MySygr and Diabetes:M application. In effectiveness and efficiency, MedicMetric and MySugr obtained almost identical results. However, participants indicated that MedicMetric supported their tasks using the Visual Information Seeking Mantra (VISM) the best overall, with 100% of participants stating that they would prefer to use the MedicMetric application. Several usability problems were identified with the IV techniques and they were addressed shortly after the study was complete. Overall participants were most satisfied with the Annotated Line View. , Thesis (MSc) -- Faculty of Science, Computing Sciences, 2022

Description: The new government faced enormous challenges when it came into office in 1994. For starters, the outgoing Apartheid leaders had thoroughly plundered the state coffers, awarding themselves and white civil servants massive pensions and 'golden handshakes'. The budget deficit was almost 9% of GDP The country/ had barely three weeks foreign exchange reserves, with a balance of payments crisis looming. The majority of inherited civil servants were generally hostile to the new government. The 'deep structures' of the State — by which I mean the ingrained habits and behaviour — were also generally hostile to the objectives of the democratic State. In addition, poverty levels were very high, and income inequality was among the worst in the world. And, of course, South Africa had the most institutionalised forms of racism in the world, which permeated through every law' and practice.

Description: In the present work, the performance of aptamer and antibody bioreceptors for the detection of the human epidermal growth factor receptor (HER2) cancer biomarker on a glassy carbon electrode is reported. The carboxylic acid group rich graphene quantum dots (GQDs) modified with gold nanoparticles and a porphyrin binuclear framework (CoP-BNF) were used to modify the glassy carbon electrode. The aptamer and antibody were both amine functionalized and attached to GQDs and CoP-BNF through an amide bond. The designed immunosensors and aptasensors in this work were characterized using electrochemical impedance spectroscopy. The aptasensors, compared to the immunosensors gave better limit of detection values. The aptasensor outperforms the immunosensor in terms of its reusability and storability, while the immunosensor could not be regenerated for subsequent experiments. The potential applicability of all sensors in this work was also investigated, by detection of HER2 in spiked human serum with acceptable results.

Description: Monkfish (Lophius vomerinus and L. vaillanti) constitute a commercially important resource off Namibia. During 1998, the Lophius resource was the fourth most important commercial resource in terms of landed mass (c. 17 000 tons) and the fifth most important commercial resource in terms of export value (U$19.8 million) of the Namibian fishing sector (Ministry of Fisheries and Marine Resources, Namibia, unpublished data). Historically, monkfish constituted an important bycatch in the trawl fishery directed at hake (Merluccius spp.), but due to increasing market demand since the early 1990s, a fishery directed at monkfish and sole (Austroglossus microlepis) has developed. The Namibian Ministry of Fisheries and Marine Resources has identified the need to develop a management plan to ensure the resource’s medium and longterm sustainability (Maartens et al. 1999). Long-term resource management plans include the identification of an assessment model to represent reality so that the implications of managing the resource in future under a range of assumptions about its present status and its future dynamics (Cochrane et al. 1998) can be examined. The aim of this study was, therefore, to assess the status of at least part of the monkfish resource using a length-based cohort assessment (Jones 1979, 1984, Sparre and Venema 1998) and an age structured production model (Punt 1994, Punt and Japp 1994, Booth and Punt 1998).
