- Description: The use of the yield curve in forecasting economic recessions is well established in the literature. A new avenue of use for the yield curve has emerged in the form of using it to forecast bull and bear stock markets. This has the potential to change how investors manage portfolios. A dynamic market-timing strategy would allow investors to shift out of or in to stock markets based on the probability of bear stock market in the future. The relationship between the yield curve and the stock market is tested using an adapted probit model. This has proven positive with encouraging results for the US, India and Spain. This is tested for South Africa using the adapted probit model and the SA yield spread. Bear stock markets are identified on the JSE and forms part of the probit modelling process. Bear markets are identified using a six- and four-month criteria. As South Africa is a small, open and developing economy, the probit is also modelled using the US yield spread. The three probit models do not appear to track bear markets well. This is substantiated through the Henriksson-Merton parametric model test which tests for market timing ability. The results for the SA yield spread using both bear market criteria do not show market timing ability, however, the SA and US yield spread model does show potential market timing ability.

- Description: South African National Parks (SANParks) manages 19 functional national parks (NPs) and oversees the conservation of South Africa’s (SA’s) biodiversity, landscapes and heritage assets. The organisation plays a significant role in the promotion of SA’s nature-based tourism business which in turn forms part of the nation’s heritage and identity. Tourism to SA’s NPs is significant and interest in visiting these parks continues to increase annually, from both international and domestic markets. Three of these NPs are located in the Eastern Cape province, namely Addo Elephant National Park (AENP), Camdeboo National Park (CNP) and Mountain Zebra National Park (MZNP) and were the focus of this study. The main reason for conducting the current study was to establish what factors make visits to the three aforementioned NPs memorable. The findings of this research could be useful to all NPs and assist them in making decisions regarding the evaluation and creation of product offerings that will enhance experiences and make them memorable for tourists. Based on the findings, and because each NP is unique (for example, the different biodiversity and landscapes), the product offerings can also be made exclusive to each NP and therefore tourists can have the opportunity for different MTEs in each park. Providing product offerings that afford MTE opportunities are particularly important for NPs, as government funding is decreasing and each NP needs to generate its own funds. Tourism is presently the economic lifeline for the parks. If NPs focus on improving current products where necessary and developing new products that provide for MTEs, NPs could increase their competitive advantage. Having a competitive advantage can ensure an increase in tourism numbers and therefore the financial sustainability of the park. Data was collected on site at each of the three NPs selected for the study, using convenience sampling to select respondents. A web-based survey was also posted on the SANParks’ website. Prior to the posting of the web-based survey, SANParks conducted a simple random sampling procedure utilising a sampling frame of tourists who had previously visited the respective NPs. The selected target population emanating from simple random sampling was e-mailed the link to the SANParks website which guided respondents to the online questionnaire if they wished to take part in the survey, hence the response sample was a convenience sample. In total, 463 usable questionnaires were received. Descriptive statistics resulted from the data analysis. A frequency analysis showed the distribution of the results, while an exploratory factors analysis (EFA) was conducted to ascertain any latent factors in the data. The results of the EFA showed the presence of three latent factors which were labelled Pleasure, Social Interaction and Discovery and Enrichment. Firstly, a strong positive correlation was shown between two of the factors, namely Pleasure and Discovery and Enrichment, and secondly, a positive correlation between two other factors, namely Social Interaction and Discovery and Enrichment was indicated. A weak correlation was shown between the factors Pleasure and Social Interaction. This research has contributed to the knowledge base regarding the factors that make a visit to AENP, CNP and MZNP memorable. Future research can make use of these factors for more exhaustive research in a wider range of NPs.

- Description: In this dissertation, the socio-ecological transformations that occurred during Cuba’s Revolución Agrícola are explored, against the backdrop of the historical subalternisation of the country as a consequence of Spanish and American imperialism, and in relation to the continuing subalternisation of the country and its people through the neoliberal mass media. To contextualize such exploration, the origins of large-scale privatization of common land, and the subsequent process of urbanization in the West, are investigated, before Cuba’s similar developmental path – as a result of Spanish colonialism, U.S. imperialism, and communist influence – is detailed. Thereafter, the way in which Cuba established an alternative food paradigm, characterised by local, communal, and urban production during the country’s ‘Special Period’ in the 1990s, is discussed, with a view to illustrating how this eco-socialist model of food production, in both rural and urban areas, led to new relations between people and nature. This Cuban model is then posited as a socio-ecologically sustainable model of food production, deserving of the attention of communities around the world, who seek to gain a degree of autonomy from neoliberal agribusiness. Conversely, the efforts of mainstream neoliberal mass media to silence the immensely positive characteristics of the revolution are also investigated, and framed in terms of the historical subjugation of Cuban voices in the American mass media, and the contemporary marginalisation of the country and its people in the neoliberal mass media. Finally, the dissertation concludes by examining the alternative media response, on the part of several prominent Cubans and those sympathetic to their cause, to bring attention to the value of the socio-ecological transformations that have occurred on the island, against the backdrop of various theorisations of the importance of alternative media platforms as a radical counterforce to neoliberal mass media hegemony.

- Description: Early stage fishes (larvae and early juveniles) were collected from an array of shallow water (±1.5m) habitats on the warm-temperate southern Angolan coastline between June 2014 and June 2015. This study, the first assessment of the early stages of coastal fishes in Angola, provides important new understanding of non-estuarine shallow water nursery habitat use by coastal fishes from the region. In total, 51 species from 18 teleost families were observed. The exposed surf zone was dominated by postflexion larvae, while the moderately exposed beach and sheltered bay were dominated by early juveniles. Both fish density and diversity peaked in the wet season (Feb – Apr 2015) for all habitats, attributed to the influx of summer spawning species. Diplodus sargus dominated catches from the exposed surf zone, and the timing of observations supports the growing consensus that sparid spawning is dictated by temperature, not season. The similitude of the observed species to those observed in warm temperate South Africa highlights the historical connection of the warm-temperate study area with warm-temperate South Africa, prior to the formation of the Benguela Current as a vicariant barrier. The classification of the study assemblage into established estuarine utilization categories showed that the surf zone hosted more exclusively marine species than comparable surf zones in South Africa, attributed to the absence of estuaries in southern Angola. However, the observation of the marine estuarine dependent Mugil cephalus in this study area devoid of estuaries suggests that estuarine dependency may be regionally specific for some taxa. It appears that the warm, sheltered, nutrient rich waters of Tombua Bay provide typically estuarine associated taxa with a suitable alternative, non-estuarine nursery habitat. This study provides evidence that the importance of estuaries as critical nursery habitats has been overemphasized for some warm-temperate coastal fishes. However, the absence of other marine estuarine dependent species from the study area suggests that some warm-temperate taxa do intrinsically rely on estuarine function for survival.

- Description: The effects of different redox mediators on the oxygen reduction reaction (ORR) catalyzed by an iron porphyrin complex, iron(III) meso-tetra(N-methyl-4-pyridyl)porphine chloride [FeIIITMPyP], in 0.1 M triflic acid were investigated by cyclic voltammetry (CV) and spectroelectrochemistry in conjunction with density functional theory (DFT) calculations. The formal potentials of the FeIIITMPyP catalyst and the redox mediators, as well as the half-wave potentials for the ORR, were determined by CV in the absence and presence of oxygen in acidic solutions. UV/Vis spectroscopic and spectroelectrochemical studies confirmed that only the 2,2′-azino-bis(3-ethylbenzothiazioline-6-sulfonic acid)diammonium salt (C18H24N6O6S4) showed effective interactions with FeIIITMPyP during the ORR. DFT calculations suggested strong interaction between FeIIITMPyP and the C18H24N6O6S4 redox mediator. The redox mediator caused lengthening of the dioxygen iron bond, which thus suggested easier dioxygen reduction. Consistent results were observed in electrochemical impedance spectroscopic measurements for which the electron-transfer kinetics were also evaluated.

- Description: The periodicity of formation of growth increments in the otoliths of South African sparids was validated by the oxytetracycline labelling technique. Intramuscular injections of oxytetracycline at a dosage of 250mg/kg marked the otoliths of laboratory held juvenile sparids, while a dosage range of 50 - 100mg/kg oxytetracycline, injected intramuscularly, marked adult sparids in the field. Laboratory held, larval sparid otoliths were marked by immersion for 24hrs a solution of 100-150mg/l alizarin complexone. Both daily (microstructural) and annual (macrostructural) growth increments were identified in the otoliths. The micro incremental pattern of deposition in the sparid otoliths conformed to the general pattern of otolith structure. Sparid otoliths consisted of a central opaque nucleus composed of multiple primordia. surrounding this nucleus were daily increments which decreased in width as the distance from the nucleus increased. Both check rings and subdaily increments were visible throughout the otolith. Minor environmental changes did not affect micro incremental deposition. Narrow opaque and wide hyaline annual growth zones were identified in sectioned sparid otoliths. Scanning electron microscope analysis of the annual growth zones revealed that microincrements within the opaque zone were narrowly spaced with prominent discontinuous phases. This resulted in the greater optical density and higher protein content of the zone. The hyaline zone was composed of widely spaced daily increments with prominent incremental phases accounting for the translucent nature of this zone. Opaque zone formation in the otoliths of many South African sparids was found to occur primarily during periods of reproductive activity and was shown to be indicative of slow otolith growth. The hyaline zone was formed after the spawning season, representative of fast otolith growth. The results of this study have resolved much of the controversy surrounding the rate of growth and time of formation of the opaque and hyaline growth zones in South African sparid otoliths.

- Description: This research sought to analyse factors that affect media freedom at the South African Broadcasting Corporation using a descriptive research design and qualitative research methodology. Studies and media reports show that the South African Broadcasting Corporation is facing a myriad of challenges including woes related to media freedom hampering its mandate to inform, educate and entertain the public of South Africa. There is a dearth of studies conducted to understand the media freedom challenges at the South African Broadcasting Corporation. A qualitative approach was used in data collection, and in-depth interviews were utilised as instruments to collect data from participants. Non-probability sampling in particular purposive sampling method was used to select 4 directors, 4 editors and 4 journalists at the South African Broadcasting Corporation. Data was analysed using thematic analysis. The findings show that challenges facing the South African Broadcasting Corporation include poor legal environment as the broadcaster lacks support from government to implement effective policies to protect employees and create a media freedom environment to allow workers to carry out their work independently. The study found that the political environment in the South African Broadcasting Corporation at affects media freedom. Some political 0rganisations, influential individuals and entities are meddling in the operation of the broadcaster by trying to influence the narrative of the content broadcasted. The finding revealed that economic environment at the broadcaster is affects media freedom. The broadcaster is struggling financially resulting in poor income for employees, retrenchments, and inability to run approved programmes. In the context of constitution and policies, there is need for the South African Broadcasting Corporation to develop strategies that will specifically address both internal and external political, economic, and legal challenges it is facing if it is to be a high performing, financially sustainable, digitised national public broadcaster that provides compelling, informative, educational, and entertaining content via all platforms. , Thesis (MA) -- Faculty of Humanities , School of language Media and Communications, 2022

- Description: This research sought to analyse factors that affect media freedom at the South African Broadcasting Corporation using a descriptive research design and qualitative research methodology. Studies and media reports show that the South African Broadcasting Corporation is facing a myriad of challenges including woes related to media freedom hampering its mandate to inform, educate and entertain the public of South Africa. There is a dearth of studies conducted to understand the media freedom challenges at the South African Broadcasting Corporation. A qualitative approach was used in data collection, and in-depth interviews were utilised as instruments to collect data from participants. Non-probability sampling in particular purposive sampling method was used to select 4 directors, 4 editors and 4 journalists at the South African Broadcasting Corporation. Data was analysed using thematic analysis. The findings show that challenges facing the South African Broadcasting Corporation include poor legal environment as the broadcaster lacks support from government to implement effective policies to protect employees and create a media freedom environment to allow workers to carry out their work independently. The study found that the political environment in the South African Broadcasting Corporation at affects media freedom. Some political 0rganisations, influential individuals and entities are meddling in the operation of the broadcaster by trying to influence the narrative of the content broadcasted. The finding revealed that economic environment at the broadcaster is affects media freedom. The broadcaster is struggling financially resulting in poor income for employees, retrenchments, and inability to run approved programmes. In the context of constitution and policies, there is need for the South African Broadcasting Corporation to develop strategies that will specifically address both internal and external political, economic, and legal challenges it is facing if it is to be a high performing, financially sustainable, digitised national public broadcaster that provides compelling, informative, educational, and entertaining content via all platforms. , Thesis (MA) -- Faculty of Humanities , School of language Media and Communications, 2022

- Description: The objectives of the study were to determine the effects of grazing systems on rangeland biomass yield and nutritional composition, tick and faecal egg counts in beef cattle across seasons. The study was conducted at Merino Walk farm located in Matatiele in the northern part of the Eastern Cape Province, South Africa. The farm was divided into three experimental plots of 3.5 ha each. Thereafter, three grazing treatments namely, Holistic Planned Grazing (HPG paddocks), Four-camp rotation (FCR) and continuous grazing (CG), were randomly allocated to the experimental plots. In the FCR system, the 3.5ha was subdivided into four 0.875-ha paddocks, while the HPG system was subdivided into ninety (90) 0.039-ha paddocks. Common forages were hand-clipped at a grazing height of (5cm) in the wet and dry season from six quadrats (0.25m2) placed in each plot and evaluated for biomass yield and nutritional composition. Thirty (30) steers of the same age 12-month old of similar weight were randomly allocated to three grazing treatments (10/treatments). Tick counts were recorded for each steer in the hot-wet, hot-dry, post-rainy and cold dry seasons. Faecal samples were collected per-rectum every in four seasons and analysed for faecal egg counts using the modified McMaster method. The data were analysed using PROC Generalized Linear Model of SAS (2012) to determine the effects of grazing system on rangeland biomass yield, nutritional composition, tick and faecal egg counts. The common grass species in all grazing system across season were Cynodon dactylon, Eragrostis chloromelus, Eragrostis plana, Fescuta and Themeda triandra. The FCR system in the wet season had significant the lowest (P<0.05) biomass yield of 62605,33kg/ha compared to other treatments which had mean values of 62625,97 and 62625,89kg/ha for HPG and CG, respectively (P<0.05). Crude protein content was higher (P<0.05) in HPG (9.41percentCP) and FCR (9.22percentCP) systems in the wet season compared to CG across seasons. Forage from HPG system, irrespective of season had significant lower starch content than other treatments (P<0.05). Forage from HPG system, irrespective of season had the lower (P<0.05) starch content than other treatments. Regardless of season, CG had higher (P<0.05) NDF (72.51 and 72.50) and ADF (41.93 and 40.45) contents than FCR and HPG treatments. Overall, HPG system regardless of season and FCR in the wet season had higher (P<0.05) in vitro digestibility at 24 and 48hrs (0.38 and 0.66) incubation periods. The tick species identified were Rhipicephalus evertsi evertsi, Rhipicephalus (Boophilus) decoloratus, Hyalomma spp and Amblyomma hebreaum with respective prevalence’s of 32percent, 29percent, 20percent and 19percent. Unidentified roundworms (URW), had the highest faecal egg counts (81.2percent) followed by Coccidia (16.4percent), Nematodirus (1.2percent) and Strongyles (1.2percent). Overall, steers on the CG system during hot-wet season had the highest individual and total tick counts (17.0) whilst those on FCR during the cold-dry season had the lowest counts (6.0). Holistic Planned Grazing had the lowest worm egg counts regardless of season, while CG had the highest counts in the hot wet season (P<0.05). The findings showed that relative to other treatments, the HPG system in wet season had a higher biomass yield and better nutritional composition (high CP, low fibre and high digestibility) with low forage production and quality under CG system during the cold-dry season. Whilst, CG during hot-wet season had the highest total tick and worm egg counts and least counts under HPG during the cold-dry. Based on relatively higher forage production and low parasite loads, HPG could be a better grazing management system than CG and FCR, especially in the wet season. It may be important to evaluate the effect of HPG on animal production, product quality and profitability prior to recommending it for use by farmers.

- Description: This treatise investigates how information technology (I.T.) enables growth in a family business (the firm) in Port Elizabeth. The firm operates in the mobile telecommunications sector. The objective of the study is to gain a deeper understanding on why family businesses adopt information technology in their firm by means of a case study. The firm found its technology (or lack thereof) completely out-dated compared to the competition and customer demands. The future of the firm was in jeopardy. The study starts with a literature review of the following three topics which form part of the scope of the research: 1. Family businesses; 2. Influence of I.T. as a driver of growth in business; and 3. An introduction into the mobile telecommunications industry. Data are collected through structured interviews with family members involved in the business. The data are consequently linked to the theory and provides insight as to what the drivers are for I.T. adoption and the required core competencies or critical success factors of the firm. Although it might seem trivial for a small family business to adopt information technology, the research concludes that I.T. is critical for continuous growth and survival of this family business. Conversely due to a lack of internal skills the firm is heavily reliant upon outside consultants for advice, implementation and support. Recommendations which are of particular interest to family businesses in a similar environment are: • Embrace technology early, utilise I.T. solutions to grow and enhance current competitive advantage, do not see I.T. as a competitive advantage alone (Pavlou & Sawy, 2006); • If information expertise is not present within the company it is advisable to invest in that expertise through recruitment, training, partnership, or outsourcing; • Ensure software meets specification / is effective enough – this can be achieved by frequent releases cycles with small changes instead of infrequent release cycles with many big changes; • Engage the consultants in a partnership by i.e. providing a profit share – this will ensure that the consultants are committed to the cause and will also ensure that their involvement is also in their own best interest; • Choose local consultants who are easily accessible – build relationships and focus on trust; • Create lock-in (Amit & Zott, 2001), provide tools free-ofcharge for customers, this will make switching to competitor more difficult; • Automate as much as possible, enable standard work practices, routinize; • Be ready to adjust the organisational structure or relinquish control (Bruquea & Moyanob, 2007)

- Description: Several studies have assumed that the plant communities of the Subtropical Thicket biome are nutritious throughout the year. This is based on the observation that they are evergreen, palatable and grow on fertile soils; however this assumption has not been tested. Therefore the aim of this study was to assess forage quality variation in the Subtropical Thicket. This was done at three levels; first we measured the plant quality of dominant plant species in the diets of Thicket herbivores. Secondly, we measured the realised diet quality of Thicket herbivores through the analysis of faecal samples. Lastly we assessed the body condition of Thicket herbivores. The study was conducted at the Colchester (plant quality and diet quality) and Addo Main Camp (body condition assessment) sections of Addo Elephant National Park. To measure the food quality of Thicket plants we analysed 10 plants that are dominant in the diets of Thicket herbivores. To measure diet quality we collected faecal samples from ten herbivores with body mass ranging from 25 kg to 6000 kg. Plant quality results showed that only 30% of the sampled plants met the high energy goat diet protein requirements and that all the sampled plants did not meet the high energy goat diet fibre requirements. This indicates that Thicket plants are not as highly nutritious as they were thought to be. The principle components analysis together with overlapping confidence intervals showed that there was no significant difference between the summer plant samples and the winter plant samples. The faecal quality results showed that there was significant seasonal difference and that faecal diet quality was a function of body size. The body condition results showed that all the sampled herbivores lost condition in the cold dry months. The evidence from faecal diet quality and body condition assessment is sufficient for us to reject the assumption that Thicket forage is consistently nutritious throughout the year. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: The African Coelacanth Ecosystem Programme (ACEP) was established in 2002 after the discovery of a colony of coelacanths off the Maputaland coast at Sodwana Bay, KwaZulu Natal. The environmental education and awareness sub-programme developed learning support materials (LSM's) for use in schools and the materials were disseminated annually through teacher education workshops. This study aimed to uncover the use of these LSM's in the rural schools of Maputaland. The active learning framework was used to analyse the materials. Collectively, the ACEP materials cover a range of active learning aspects; however alignment with the curriculum has resulted in an increased focus on experiments, accompanied by a loss of environmental content and a narrowing scope for active environmental learning. Workshop questionnaires and four school case studies revealed the patterns of practice of use of materials in schools. The stated use of materials by teachers is not fully realized in the actual classroom practice which centres on learning content and concept definitions. There is no culture of use of materials in the schools following the annual introduction of ACEP materials. It was also found that the marine and coastal knowledge holding power is outside the realm of the teachers' practice and control. The findings of this study come at a time when there is uncertainty over the future of South African education and the curriculum. This research may inform the environmental education and coastal and marine education field as to their role in education and more specifically the development of learning support materials.

But a closer study will reveal that darkness is also a positive force; examples can be cited from various cultures where darkness was thought to have given birth to light. The subterranean is the realm of fertility; the worshippers of Dionysius realised this, as did the followers of the world-wide cult of the Great Earth Mother.

- Description: The inclusion of the right of access to social security in the Constitution did not meet with wholehearted approval in South Africa. This right, however, is of vital importance for the future upliftment of the country. The present social security system is based upon a clear distinction between social assistance and social insurance. There is a gap in current social security provisions in that the unemployed middle aged individual is not covered. Unemployment itself is one of the greatest challenges obscuring the implementation of a comprehensive social security system. The Constitutional right is to have ‘access’ to social security and the amount of resources at the state’s disposal is directly related to increasing this right, although it is true that a number of available resources are misspent. The state must take reasonable legislative and other measures, within its available resources, to achieve the progressive realisation of the right of access to social security. The principles of solidarity and ubuntu must be cultivated so that national social development becomes a concern for all citizens. There are numerous problems facing South Africans in attaining the goal of access to social security – even if national social development does become a priority. Budgetary constraints, poverty, unemployment, HIV/Aids and foreigners are examples of these. By making social security a priority for everyone, existing ideas (almost all of which have merit) may be converted into long-term solutions for poverty and unemployment. Currently, numerous opportunities to salvage the situation are being overlooked as a result of the lack of a comprehensive and structured plan to better the access to social security. The constitutional right of access to social security is enforceable, although the jurisprudence in this field remains underdeveloped. Conditions are currently favourable, within the country and beyond its borders, for an imaginative and concerted attempt to be made to find potential solutions. It is possible for resources to be increased and for tax benefits to be incorporated for businesses which have the capacity to contribute. The issue of defence spending is controversial, but could hold the key to lowering unemployment. Should jobs be created, it is likely that they will initially be of a temporary nature. Consequently, provisions are needed to ensure some guarantee of income in the lacuna between when a job is lost and another found. Ultimately, one thing is certain: the constitutional right of access to social security will only be complete once the people who are recipients of this right make sacrifices and create corresponding duties for themselves to ensure that the next generation of inhabitants of this country are not facing similar problems. The state’s goal should be to ensure that the basic rights which all people enjoy in terms of the Constitution (in particular the other socio-economic rights) are guaranteed for the duration of their existence, even if the level of benefits received by such people is low.

The present social security system is based upon a clear distinction between social assistance and social insurance. There is a gap in current social security provisions in that the unemployed middle aged individual is not covered. Unemployment itself is one of the greatest challenges obscuring the implementation of a comprehensive social security system. The Constitutional right is to have ‘access’ to social security and the amount of resources at the state’s disposal is directly related to increasing this right, although it is true that a number of available resources are misspent. The state must take reasonable legislative and other measures, within its available resources, to achieve the progressive realisation of the right of access to social security. The principles of solidarity and ubuntu must be cultivated so that national social development becomes a concern for all citizens. There are numerous problems facing South Africans in attaining the goal of access to social security – even if national social development does become a priority. Budgetary constraints, poverty, unemployment, HIV/Aids and foreigners are examples of these. By making social security a priority for everyone, existing ideas (almost all of which have merit) may be converted into long-term solutions for poverty and unemployment. Currently, numerous opportunities to salvage the situation are being overlooked as a result of the lack of a comprehensive and structured plan to better the access to social security. The constitutional right of access to social security is enforceable, although the jurisprudence in this field remains underdeveloped. Conditions are currently favourable, within the country and beyond its borders, for an imaginative and concerted attempt to be made to find potential solutions. It is possible for resources to be increased and for tax benefits to be incorporated for businesses which have the capacity to contribute. The issue of defence spending is controversial, but could hold the key to lowering unemployment. Should jobs be created, it is likely that they will initially be of a temporary nature. Consequently, provisions are needed to ensure some guarantee of income in the lacuna between when a job is lost and another found. Ultimately, one thing is certain: the constitutional right of access to social security will only be complete once the people who are recipients of this right make sacrifices and create corresponding duties for themselves to ensure that the next generation of inhabitants of this country are not facing similar problems. The state’s goal should be to ensure that the basic rights which all people enjoy in terms of the Constitution (in particular the other socio-economic rights) are guaranteed for the duration of their existence, even if the level of benefits received by such people is low.

Retention of medical doctors in the public health sector: a case study of the Port Elizabeth Hospital complex
- Authors: Guvava, Dorothy Dorica
- Date: 2008
- Subjects: Employee retention -- Port Elizabeth -- South Africa , Physicians -- Job satisfaction -- South Africa -- Port Elizabeth , Hospitals -- South Africa -- Port Elizabeth
- Language: English
- Type: Thesis , Masters , MA

- Description: The Port Elizabeth (PE) hospital complex is one of the public hospital groups in South Africa facing a critical shortage of medical practitioners, with reference to doctors in particular. In the quest of finding how to retain doctors in the hospital complex, the aims of this research were to survey doctors’ career intentions; to investigate factors that could be contributing to these career intentions so as to uncover some of the reasons why doctors are leaving the public sector; and to identify effective ways in which the government and hospitals might improve retention by pointing out areas that need improvement. The factors that influence doctors’ career intention included income, work conditions, risk of contracting infection, risk of injury at work, hours of work, work load, work related stress, paid leave days, resources, personal growth and development opportunities, ongoing training opportunities, advancement and promotion opportunities, relation with co-workers, relations with supervisor/superiors, and sense of meaning. Findings revealed that even though the tendency to leave’ group (43%) was smaller than the ‘tendency to stay’ (57%), the majority (85%) of those who intended to leave were younger doctors. Despite some significant differences in responses between the two groups, results revealed that both groups were dissatisfied with almost all conditions of work apart from relationships with supervisors and co-workers. To a large extent, both groups revealed that work conditions are better in the private hospitals than in their current hospitals. viii The fact that some doctors could stay in the public hospital sector despite intense dissatisfaction with conditions of work, and despite the perception that that there are better options in the private hospitals could be attributed to the fact that most of these doctors are older and are at their retirement stage . Adding to this is that most of these doctors, who indicated willingness to say, scored high in sense of meaning as a factor influencing their career intention. This research was based on the assumption that there was no retention strategy put in place to solve the problems facing PE hospital complex. However, during this research a strategy was being developed and implemented by the Eastern Cape Department of Health. Therefore, evaluation and recommendations of the strategy are provided in the conclusions of the study. These recommendations relate not only to the implementation of the strategy, but improving it to accommodate all problems currently facing the doctors and finding ways and means of making the strategy sustainable; creating private-public partnerships; focusing on creating a sense of meaning amongst the doctors (especially the younger ones) and focusing on retaining the risk group which was the younger doctors.

- Description: This paper explores climate as variable natural forces driving seasonal cycles1 that many African cultures had adjusted themselves to within intergenerational knowledge practices of longue durée. The study points to the need to re-orientate and expand climate science education so that it is centred on the seasonal cycles and intergenerational learning to better align transitioning to future sustainability with these in our southern African contexts of climate change today. The narrative touches upon historical accounts of knowledge practices amongst the Krobo, Bemba, Shona, Zulu and Xhosa, briefly pointing to how each, as an African culture, is situated as a social-ecological entity within the climatic tapestries of our African landscapes. It takes note of how cultural articulation within the seasonal cycles of regional climate have a long history with adaptive change in some contexts in more recent times. The review suggests that our learning in relation to emerging climate change should be informed by these histories of intergenerational knowledge practice. It notes how a better grasp of these could be important drivers of a widening cultural response to the changing dynamics in our climatic surroundings today. The brief study suggests that southern Africa is a special place with many unique and interesting climatic processes and associated socio-ecological systems and practices. These can provide engaging perspectives for informing education to mitigate or adapt to climate change. Here, a situated exploration of seasonal cycles can draw on both the latest in modern climate science and the rich social-ecological heritage of Africa briefly touched upon in the study. A model of process is offered for how both can be used in a seasonal cycles approach climate change education. This better situated and more inclusive approach can enable us to contemplate how we might best adjust our social-ecological dispositions and practices in the changing world that we all share.
