- Description: The last two decades have been characterised by a phenomenal rise in the outsourcing of services to external service providers. The driver of this trend has been largely economic, since outsourcing offers more competitive price points for the same service at a comparable service level. Beyond the cost saving objective, the rationale for outsourcing has been to drive core strategy. However, with the economic slowdown, declining consumption and production are forcing entrepreneurs to change their way of thinking about the management of companies. Notably, in recent years there has been a small but a growing reversal of this trend where companies that have previously outsourced functions are being brought back in-house. One of the major concerns surrounding these changes of business strategies is the extent to which the employee rights are safeguarded.

- Description: Plants often are simultaneously attacked by several herbivores that can affect each other’s performance, and their interaction may affect their host plant fitness. The current study was conducted to determine the interaction between the root-feeding beetle, Longitarsus bethae Savini & Escalona (Coleoptera: Chrysomelidae) and a root-knot nematode, Meloidogyne javanica (Treub) Chitwood (Tylenchida: Heteroderidae), with implications for the biological control of Lantana camara L. (Verbenaceae) in South Africa. The studies were conducted under quarantine conditions at the Agricultural Research Council-PHP, Roodeplaat, Pretoria, South Africa. Specifically, the study determined; (i) whether root damage by the flea beetle enhanced infection by M. javanica, (ii) whether L. camara roots infected with the nematode enhanced the performance of the beetle, (iii) whether single or combined effect of the two organisms (i.e. L. bethae and M. javanica) had an overall effect on the growth and biomass of their shared host, L. camara, and (iv) the susceptibility of 10 L. camara varieties that are commonly found in South Africa to M. javanica. The study found that galling on the roots of L. camara by the nematode occurs at the highest inoculation of 300 eggs of L. bethae per plant, and no galling occurred at inoculation of 200 eggs per plant and below. The findings also showed that L. bethae performed better on M. javanica-infected than on healthy L. camara roots, and that more L. bethae adult progeny with slightly bigger body size emerged from M. javanica-infected, than from healthy plants. Fresh weight (galls) of plant roots from treatments where both species (i.e., L. bethae and M. javanica) were combined was significantly higher than that from plants infected with the nematode only, suggesting that the combination of both species induces more galling than the nematode does alone. The above-ground dry biomass was significantly lower both in combined and M. javanica only treatments, than in L. bethae only treatment. The study also found that selected L. camara varieties were infected with M. javanica, albeit at varying degrees of infection. Among the 10 L. camara varieties, Orange Red OR 015 was the most susceptible. Other susceptible varieties included Light Pink 009 LP, Total Pink 021 TP and Dark Pink 018 DP, and these, together with variety Orange Red OR 015, constituted 40% of the L. camara varieties evaluated in the current study. Fifty percent of the varieties displayed slight to moderate susceptibility to M. javanica, while 10% displayed lack of susceptibility. The study concluded that the symbiotic relationship between L. bethae and M. javanica was mutual, resulting in increase in the fitness of the beetle. The combined herbivory by L. bethae and M. javanica was also found to be additive on one of the most common varieties of L. camara in South Africa, and therefore co-infestation by both species might enhance the biological control of this weed in South Africa. The study further concluded that the suitability of some invasive L. camara cultivars such as Light Pink 009 LP and Orange Red 015 OR for M. javanica, might also contribute towards biological control of this weed in South Africa, particularly in areas where the two herbivores species co-exist.

- Description: The aim of the study was to explore the experiences of student nurses regarding the implementation of CBE and allow them to tell their story of how CBE impacted to their academic experience. Purposive non-probability sampling was the method of choice. The following research question guided this study: What are the experiences of nursing students at the nursing college on the implementation of CBE as a teaching-learning strategy? The participants in this study were the fourth year students registered in the four year diploma and have been exposed to CBE, according to regulation 425 of the Nursing Act, 2005(Act No.33 of 2005). Fifty (50) students voluntarily participated in the focus groups discussions. Data analysis was done concurrently with data collection. Data was analysed manually as it was categorised into themes, categories, and subcatagories. For this study, a category system/ template was developed to code the data according to the categories, therefore related concepts were grouped together to facilitate the coding process. The final analysis led to the development of a report presenting the interpretation and presentation of results. RESULTS The study results revealed that students had benefited from CBE as a teaching learning strategy. Furthermore, participants reported that CBE had an impact in their training in terms of acquisition of skills, personal and professional growth and correlation of theory to practice. Discussions of findings, along with recommendations for practice conclude the study. Suggestions might be made to improve ways in the implementation of CBE in the nursing college

- Description: Calibration of radio interferometric data is one of the most important steps that are required to produce high dynamic range radio maps with high fidelity. However, naive calibration (inaccurate knowledge of the sky and instruments) leads to the formation of calibration artefacts: the generation of spurious sources and the deformations in the structure of extended sources. A particular class of calibration artefacts, called ghost sources, which results from calibration with incomplete sky models has been extensively studied by Grobler et al. (2014, 2016) and Wijnholds et al. (2016). They developed a framework which can be used to predict the fluxes and positions of ghost sources. This work uses the approach initiated by these authors to study the calibration artefacts and ghost sources that are produced when variable sources are not considered in sky models during calibration. This work investigates both long-term and short-term variability and uses the root mean square (rms) and power spectrum as metrics to evaluate the “quality” of the residual visibilities obtained through calibration. We show that the overestimation and underestimation of source flux density during calibration produces similar but symmetrically opposite results. We show that calibration artefacts from sky model errors are not normally distributed. This prevents them from being removed by employing advanced techniques, such as stacking. The power spectrums measured from the residuals with a variable source was significantly higher than those from residuals without a variable source. This implies advanced calibration techniques and sky model completeness will be required for studies such as probing the Epoch of Reoinization, where we seek to detect faint signals below thermal noise.

- Description: Significant changes have occurred in South Africa during the past decades in household saving and borrowing behaviour. The rapid increase in South Africa’s household debt over the last twenty years has been an international phenomenon. In most countries, household debt increased from the 1990s until the crisis of 2007–2008 before stabilising due to a recession and deleveraging. The study used an ARDL model to investigate the determinants of household debt in South Africa. Pairwise regression is used to select the most relevant variables affecting household regression in the country. The results of the study showed that consumer confidence, the bond market index and the vulnerability index have a positive effect on household debt. As consumers' faith in the performance of the economy increases, household debt also increases as expected, reflecting consumers' belief in increased future wealth. The positive influence of the vulnerability index suggests that households tend to resort to borrowing to smooth consumption when incomes and other related factors decline. It is recommended that national policy should tighten regulations around access to unsecured credit to minimise the stress on already vulnerable households.

- Description: Successful destination marketing often begins with the development and implementation of a well-designed strategic marketing plan that promotes a targeted, cooperative and strategic approach to destination marketing. Consequently, astute destination marketers should seek to understand the needs, motives and preferences of carefully selected visitor segments, so that tourism organisations, agents and operators can identify market segments, choose target markets and position brands for marketing strategies and selling activities (Cox and Wray, 2011). This quest to understand consumer decision-making presents one of the most important challenges to success in tourism marketing. A large amount of research has been made in what Van Raaij and Crotts (1994) describe as the “economic psychology” in travel and tourism (see Hu, 1996). This study focuses on psychological and cultural influences on consumer preferences for popular tourist activities. The results of the study are important for the tourism industry as they directly affect marketing strategy. A number of authors have elaborated on the central role played by local and regional destination marketing organisations (DMOs) in helping to strengthen economic linkages in the tourism industry, to enhance collaboration, and to facilitate strategic marketing initiatives (e.g. Soteriades, 2012; Bowes in Goodall & Ashworth, 2013). One such organisation is the Eastern Cape Parks and Tourism Agency (ECPTA) based in East London, South Africa. Established in 2010 by the provincial government, the agency actively pursues “equitable low-carbon economic growth through innovation and collaboration” in both the conservation and tourism industries (ECPTA, 2015). The Eastern Cape has been dubbed the “Adventure Province” and boasts “a rich history, moderate climate, a wealth of natural resources” – an enviable combination of advantages that are leveraged in attracting visitors to the region (EC DEDEA, 2015). Among various marketing initiatives pursuant of its mandate, the ECPTA has established an online portal at www.visiteasterncape.co.za that potentially serves as an important information resource for visitors. The portal conveniently lists eight categories of tourist activities, each category linking the visitor to lists of specific offerings provided at local level in various parts of the province. A practical question that arises is the focus of the current research: Which market segments are most attracted to these offerings? The insights gleaned from the present study can thus contribute to ongoing research on approaches to improving the effectiveness of destination marketing aimed at holiday makers around the world. Previous research into the economic psychology of travel and tourism includes that of Van Raaij and Crotts (1995) whose seminal paper provides a theoretical background and delineates specific applications of the concept in the tourism industry. The framework for information processing they provide is reflected in Goodall’s outline of the tourist’s annual holiday search process (in Goodall & Ashworth, 2013). Following this thread, Mansfeld (1992) discusses the role and complex nature of motivation in travel behaviour, specifically in the stages of assessment and the elimination of destination alternatives. Gnoth’s (1997) theoretical study clarifies the relationship between tourists’ motivations and the formation of expectations, based on a discussion of the notions of drive reduction, attitudes and values. Goossens (2000) provides a conceptual model on the factors that influence the pleasure travel choice process, showing how the consumer’s disposition and marketing stimuli combine to create involvement in the information processing, which leads to hedonistic responses and motivation to travel. Various models have been developed and used to examine tourist decision making, including Mansfeld’s (1996) “value stretch” model, the LOGIT model used by Costa and Manente (1996) to evaluate the main characteristics of visitors, Tsaur and Tzeng’s (1996) multi-attribute decision making model used to analyse perceptions of service quality at hotels, the LOCAT model by Moutinho and Curry (1994) used in site location analysis and selection, and the MNL model used by Winzar et al. (1993) in analysing perceptions of transport mode attributes. Efforts to further enrich marketers’ understanding of tourist behaviour include new market segmentation methodologies developed to accurately predict tourist activity choices. Johar and Sirgy (1996) for example, introduce a technique called segment congruence analysis to help travel and tourism marketers determine the actionability of potential or viable market segments. Mazanec (1992) introduces a neural network model to classify tourists and argues that this method surpasses discriminant analysis in determining a subject’s correct segment affiliation. The present study is an effort to explore further the notion of tourist market segmentation by observing how psychographic and demographic variables work together to influence tourist activity and destination preferences.

Abstract art and the contested ground of African modernisms

- Description: This submission for a Masters of Fine Art consists of a thesis titled Abstract Art and the Contested Ground of African Modernisms developed as a document to support the exhibition Time in Between. The exhibition addresses the fact that nothing is permanent in life, and uses abstract paintings that reveal in-between time through an engagement with the processes of ageing and decaying. Life is always a temporary situation, an idea which I develop as Time in Between, the beginning and the ending, the young and the aged, the new and the old. In my painting practice I break down these dichotomies, questioning how abstractions engage with the relative notion of time and how this links to the processes of ageing and decaying in life. I relate this ageing process to the aesthetic process of moving from representational art to semi-abstract art, and to complete abstraction, when the object or material reaches a wholly unrecognisable stage. My practice is concerned not only with the aesthetics of these paintings but also, more importantly, with translating each specific theme into the formal qualities of abstraction. In my thesis I analyse abstraction in relation to ‘African Modernisms’ and critique the notion that African abstraction is not ‘African’ but a mere copy of Western Modernism. In response to this notion, I have used a study of abstraction to interrogate notions of so-called ‘African-ness’ or ‘Zambian-ness’, whilst simultaneously challenging the Western stereotypical view of African modern art. I have also related the theoretical and practical analysis of abstraction to scholarly debates on abstraction and ‘African Modernism’, arguing for multiple African Modernisms.

- Description: This submission for a Masters of Fine Art consists of a thesis titled Abstract Art and the Contested Ground of African Modernisms developed as a document to support the exhibition Time in Between. The exhibition addresses the fact that nothing is permanent in life, and uses abstract paintings that reveal in-between time through an engagement with the processes of ageing and decaying. Life is always a temporary situation, an idea which I develop as Time in Between, the beginning and the ending, the young and the aged, the new and the old. In my painting practice I break down these dichotomies, questioning how abstractions engage with the relative notion of time and how this links to the processes of ageing and decaying in life. I relate this ageing process to the aesthetic process of moving from representational art to semi-abstract art, and to complete abstraction, when the object or material reaches a wholly unrecognisable stage. My practice is concerned not only with the aesthetics of these paintings but also, more importantly, with translating each specific theme into the formal qualities of abstraction. In my thesis I analyse abstraction in relation to ‘African Modernisms’ and critique the notion that African abstraction is not ‘African’ but a mere copy of Western Modernism.

- Description: Biomass gasification has become a study of great interest over the years and plant biomass with cellulose, hemicellulose, and lignin found to be an ideal resource for conversion into heat and power through thermochemical processes such as gasification. The inadequate supply of the energy in the country has become critical with the national energy provider struggling to meet the energy demands of the ever growing population of South Africa. The depletion of natural resources and the unstable prices as well as the cost of transporting the fuels together with the environmental effects of burning fossil fuels are contributing factors to the energy crisis. Alternative sources of energy that are locally available, sustainable, and environmentally friendly are presently in demand as municipal organic wastes has been considered a source of renewable energy with gasification deemed one of the leading edge technologies to harness the energy. This research only studied the characteristics and kinetics of selected municipal organic waste including decaying wood, tomatoes, onions, cabbage, butternut and bones. The research did not involve the gasification process because of expenses associated with gasification processes, however, this has been considered as future studies under the conditions of available resources to carry out the actual gasification experiments. The characteristics of selected municipal organic wastes for energy conversion through gasification were actually investigated in this study and the implication of the value of each property interpreted in relation to gasification with specific reference to information available in the literature. Proximate analysis conducted on the wastes indicate that the physical properties in terms of the weight percentages of moisture, volatile matter fixed carbon and ash contents of the wastes vary considerably, especially with regards to the last three properties. The reason for this wide variation was attributed to the source of the wastes and the standard of living of the people vi in the area where the wastes were collected. However, the values obtained for these properties are within limits for the wastes to be adequately used as feedstocks in a gasification process, except for their content of ash, which was significantly high in all of the wastes for the aforementioned reasons. The ultimate analysis of the wastes as determined using the Energy Dispersive X-ray spectroscopy gave the percentage composition of the chemical elements present in the wastes, which suggest that carbon is the chief elemental constituent of the wastes. The highest carbon content of about 47% was recorded for bone due again to the reasons previously adduced. According to McKendry, 2002, the high carbon content of the wastes implies increased calorific value as well as increased gas production during gasification. A number of ash–forming elements were also found in the wastes, which included magnesium and potassium in low concentrations that does not pose any technical challenges during gasification, although their concentration may increase under high temperature gasification, which may equally result to some catalytic effect that would contribute to the overall gasification efficiency (Anukam et al., 2016). Calorific value analysis also suggests that the wastes contain reasonable amount of energy that can be converted to useful energy through gasification. Although, variation in calorific value was also noted, the highest calorific value of about 18 MJ/kg was recoded for bones, which correlates its data on the highest carbon content of all wastes. However, the data on the calorific value of the wastes suggests that the wastes are well suited for gasification by virtue of their calorific value. FTIR analysis revealed the major functional groups present in the internal structure of the wastes. The common functional groups observed were the OH group found in the band around 3600–3400cm-1 for most of the wastes; the C–H stretching band at 2970-2780 cm-1; and the C–O as well as the C–O–C observed in the region of 1740–1710 cm-1 and 1250-1220 cm-1 for all samples, respectively. Most functional group in the internal structures of gasification feedstocks function to facilitate faster vii rates of reaction and consequently faster rates of gasification that contributes to optimum efficiency under any conditions of gasification (Anukam et al., 2016). While thermogravimetric analysis established thermal parameters that are likely to have positive influence on the gasification of the wastes, kinetic investigation revealed two parameters that may also impact on the gasification of the wastes. These are activation energy and pre–exponential factor, which were found to be in good agreement with the values obtained in the literature even though variation in these parameters was noted. The values obtained for activation energy and pre–exponential factor using the Kissinger method of kinetic analysis showed a far less value for these two parameters when compared to commonly used feedstocks like wood and coal. This was a reason attributed to the chemical characteristics of the wastes, mainly their lower content of carbon compared to these two (wood and coal) commonly used fuels.

While the major nutrient requirements of the species are known, the advantages of incorporating formulated feeds into the diet of the species has yet to be fully explored. Research on formulated feed composition is required to: minimise input costs; improve the organoleptic properties and meat quality; and minimise nutrient loss, which contributes to environmental pollution. This study sought to test the impact of different lipid levels in aquafeeds fed to dusky kob juveniles by determining: (i) growth performance, feeding efficiency, proximate and fatty acid composition; (ii) chemical changes and shelf-life of refrigerated fish fillets; and (iii) metabolic rates and nitrogen excretion of juvenile dusky kob.

- Description: Human African trypanosomiasis (HAT) is a public health problem in sub-Saharan Africa, with approximately 10,000 cases being reported per year. The Macrophage Migration Inhibitory Factor (MIF) which is encoded by a functionally polymorphic gene is important in both innate andadaptive immune responses, and has been implicated in affecting the outcome and processes of several inflammatory conditions. A recent study in mice to that effect showed that MIF deficient and anti-MIF antibody treated mice showed lowered inflammatory responses, liver damage and anaemia than the wild type mice when experimentally challenged with Trypanosomes. These findings could mean that the transcript levels and/or polymorphisms in this gene can possibly affect individual risk to trypanosomiasis. This is especially of interest because there have been reports of spontaneous recovery i.e self-cure/resistance in some HAT cases in West Africa. Prior to this discovery the general paradigm was that trypanosomiasis is fatal if left untreated. The aim of this study was to gain insights into how human genetic variation in forms of nonsynonymous SNPs affects the MIF structure and function and possibly HAT susceptibility. NsSNPs in the mif gene were obtained from dbSNP. Through homology modeling, SNP prediction tools, protein interface analysis, alanine scanning, changes in free energy of folding, protein interactions calculator (PIC), and molecular dynamics simulations, SNP effects on the protein structure and function were studied. The study cohort comprised of human genome sequence data from 50 North Western Uganda Lugbara endemic individuals of whom 20 were cases (previous HAT patients) and 30 were controls (HAT free individuals). None of the 26 nsSNPs retrieved from dbSNP (July 2015) were present in the mif gene region in the study cohort. Out of the eight variants called in the mif coding region there was only one missense variant rs36065127 whose clinical significance is unknown. It was not possible to test for association of this variant with HAT due to its low global MAF that was less than 0.05. Alanine scanning provided a fast and computationally cheap means of quickly assessing nsSNPs of importance. NsSNPs that were interface residues were more likely to be hotspots (important in protein stability). Assessment of possible compensatory mutations using PIC analysis showed that some nsSNP sites were interacting with others, but this requires further experimentation. Analysis of changes in free energy using FOLDX was not enough to predict which nsSNPs would adversely affect protein structure, function and kinetics. The MD simulations were unfortunately too short to glean any meaningful inferences. This was the first genetic study carried out on the people of Lugbara ethnicity from North Western Uganda.

- Description: Selecting appropriate normative data for the purpose of evaluating psychometric test scores forms an integral part of the interpretative psychological assessment process. This highlights the well-known problem of utilising measures developed in the United Kingdom (UK), or the United States (US) and accepting their norms unreservedly for the practice on local populations, which questions the tests’ validity and reliability. The current study, which aimed to collect normative indicators on the Bender Gestalt Test (Second Edition), forms part of the continuing effort to develop norms for psychological tests in South Africa, and to focus on the valid and reliable use of measures within the context of South Africa’s multicultural and multilingual population groups. The participants of the research were Black isiXhosa-speaking Grade 3 and Grade 7 learners aged 8 to 9 years (N = 38 ), and 12 to 13 years (N = 23), obtaining their school education in the disadvantaged educational setting of the former Department of Education and Training (ex-DET) schools. The tests were scored according to the Bender Gestalt Test (Second Edition) manual, using the Global Scoring System. Thereafter, the raw scores were converted to Standard Scores, T-scores and Percentile Ranks using the US normative tables, according to chronological age categories. When the two groups were compared to the US norms, the results equated favourably for the present study sample. There were no significant findings in relation to the classroom size or any difference in performance between the schools who participated. The only significant difference revealed between male and female participants was with the Grade 7 sample group, where the males scored significantly lower than females on the Recall phase. These results support the prospect of the continuous revision of norms, and it is suggesting that the cognitive processes measured by this test are likely to derive from robust neurological substrates that are relatively stable across cultural groups.

- Description: This study was conducted to assess the effect of including Tenebrio molitor larvae (T. molitor L) as a protein source in different diets on broiler performance, carcass characteristics and meat quality. A total of 144 day-old Cobb-500 chicks were randomly allocated into three treatment groups, each was allocated 16 birds and reared in 9 identical pens. Experimental diets used were as follows: T1 Control (no T. molitor L inclusion); T2 and T3 contained levels of T. molitor L at 5 percent and 10 percent of dry matter (DM) intake, respectively. Body weights (BW), average daily gain (ADG), feed intake (FI), and Feed conversion ratio (FCR) were measured for the 1st experimental chapter. For the second experimental chapter; live weights (LW) of broilers were recorded before slaughter and thereafter carcass weights (CW), meat yield (weights of breast, thigh, drumstick and wing) were recorded. The dressing percentage (DP percent) was also calculated. Breast muscles were sampled for meat pH and colour measurements. The LW of birds from T1 (0 percent T. molitor L) were significantly different (P<0.05) from both T2 (5 percent T. molitor L) and T3 (10 percent T. molitor L) which were similar to each other, with T2 exhibiting the highest live weights (2166g) and the control treatment exhibiting the lowest live weights (2018.3g). In CW, T1 was significantly different (P<0.05) from T2 while it was similar (P>0.05) to T3. The dressing percent of T1 was significantly different (P<0.05) from T2 and T3 which were similar to each other, with T2 having the highest dressing percentage (78, 2 percent) and T1 having the lowest DP percent (66 percent). The breasts in T2 were significantly higher and different (P<0.05) from both T1 and T3 which were similar to each other. The drumsticks in T3 were significantly different (P<0.05) from T1 while they were similar to T2 with values with T2 having highest values. After 45 minutes of slaughter, a significant difference (P<0.05) was observed in L⃰ among all treatments. In redness (a⃰), T3 was significantly different from T1 but was similar to T2 and all treatments in this study exhibited a darker red meat, with T3 muscles exhibiting darker red colour than the other treatments. Similar results were observed in yellowness (b⃰), where the breast muscles from T3 were more yellow than the other treatments. After 24 hours of slaughter, T2 L⃰ values were significantly different (P<0.05) from both T1 and T3 which were similar to each other. It was also found that the broiler chickens given diet with no T. molitor L inclusion (T1) had lower values of BW, FI, ADG and FCR throughout the experiment than those that were in T2 and T3 with 5 percent and 10 percent T. molitor L inclusion levels, respectively. However, it was also found that although broilers with 5 percent T. molitor L inclusion (T2) in their diet had high ABW and ADG than the broilers with 10 percent T. molitor L inclusion (T3), the T3 birds compared favourably to T2 birds as they required low feed intake to reach the same slaughter weight due to high FCR. It was, therefore, concluded that T. molitor L meal can be incorporated into the diets of broilers to produce heavy birds either at 5 or 10 percent. However, although 5 percent T. molitor L inclusion yields heavier carcasses, the 10 percent T. molitor L inclusion compared favourably to 5 percent inclusion since it required low feed intake to reach the same slaughter weights and there were slight differences on meat quality attributes between the two treatments.Thus T. molitor L at 10 percent inclusion levels was the best inclusion level to enhance broiler growth performance, carcass yield, meat yield and meat quality.

- Description: In light of the cyber-activist simulated incidences dubbed Occupy Wall Street in New York City, New York, USA and the mirrored Occupy JSE movement in Johannesburg, South Africa, the internet and its social media networking sites have been instrumental in facilitating both the dissemination of information as well as facilitating a mediated environment for activists to coordinate online and offline protest action. This research examines the extent to which activists for social change have used social media sites such as Facebook, YouTube, web blogs and other online forums to garner support for their cause as well as generate social mobilization by creating awareness of the economic disparities in their respective societies. Established theories of social presence have been used to explain the relevance and role of social media tools in instigating social mobilization whether online or offline. This discussion focuses on the Occupation Movements staged in various countries globally and to what extent social media played in facilitating social change. It is important to note that the video footage and other social media data under analysis is specifically that which was uploaded onto YouTube and the subsequent URL links posted on Facebook. By scrutinizing these videos and calls for action as well as the comments posted by the international online community, this research elucidates the ‘trickling down effect’ of this type of cyber-activism on the behavioural patterns of contemporary South African society, and further argues that this process is indicative in the resultant Occupy JSE movement

- Description: Primary health care is pivotal to the growth of a country’s economy by improving the health and social well-being of its people. Several efforts and structures have been put in place to ensure that all South Africans have access to health facilities as well as representation in the health facilities, just as community members are represented in schools and other boards. Health committees play an important and integral role to the community and health facilities by being mediators between the community and the health facility (Padarath &Friedman, 2008). The Eastern Cape is one of the provinces that has health committees that are fully functional and a number of factors including the collaboration of key stakeholders (facility managers, community members, clinic staff and ward councillors) contribute to why health committees have been operational in the Eastern Cape(Padarath &Friedman , 2008). It becomes critical to investigate factors that sustain health committees in Nelson Mandela Bay. This chapter introduces the research topic, purpose, rationale and background as well as the objectives of the study. The research focuses on investigating the sustainability of health committees in Nelson Mandela Bay therefore making it critical to define the term sustainability. Conceptualizing sustainability has been ongoing with various definitions from learners from different backgrounds. Sustainability as a concept emanates from different dimensions namely, scientific, political economic and indigenous dimension. Sustainability has been described by scholars as a state of well-being and as an evolutionary process (Dimitrov, 2010). Sustainability is regarded as a state of well being whereby humans can live in co-exist with the natural world, this definition takes into account issues to do with good health , cultural identity, personal security and freedom of choice. Sustainability- well being brings out a lot of questions and problems in identifying the fundamentals values of sustainability. It is continuously debated amoung scholars if sustainability of well being pertains only to the health conditions of human beings or it should be extended to others (Dimitrov, 2010) “Sustainability that is restricted to the well being of humans is related to Notions about security of individual/community health together with financial security together with financial security; the planet is regarded as a resource to further this end (Dimitrov, 2010:4) If however well-being definitions of sustainability are construed to preserving and protecting the environment as well as biodiversity of other species (plant and animals) then the normative definitions of sustainability from this viewpoint are tendered with notions of global Environmental stability, ecological considerations and security of ecosystems” (Dimitrov, 2010:4).

- Description: Spread F is a phenomenon of the ionosphere in which the pulses returned from the ionosphere are of a much greater duration than the transmitted ones. The occurrence of spread F can be predicted using the technique of Neural Networks (NNs). This thesis presents the development and evaluation of NN based models (two single station models and a regional model) for predicting the occurrence of spread F over selected stations within the Brazilian sector. The input space for the NNs included the day number (seasonal variation), hour (diurnal variation), sunspot number (measure of the solar activity), magnetic index (measure of the magnetic activity) and magnetic position (latitude, magnetic declination and inclination). Twelve years of spread F data measured during 1978 to 1989 inclusively at the equatorial site Fortaleza and low latitude site Cachoeira Paulista are used in the development of an input space and NN architecture for the NN models. Spread F data that is believed to be related to plasma bubble developments (range spread F) were used in the development of the models while those associated with narrow spectrum irregularities that occur near the F layer (frequency spread F) were excluded. The results of the models show the dependency of the probability of spread F as a function of local time, season and latitude. The models also illustrate some characteristics of spread F such as the onset and peak occurrence of spread F as a function of distance from the equator. Results from these models are presented in this thesis and compared to measured data and to modelled data obtained with an empirical model developed for the same purpose.

- Description: Regional community in southern Africa has been limited to the region’s states. As a result, deeper notions of community emanating from non-state actors, particularly transnational social movements, continue to be ignored. In an attempt to transcend state centrism, this thesis highlights alternative forms of regional community by exploring the Zion Christian Church (ZCC), one of southern Africa’s biggest and fastest growing cross-border movements. The ZCC is a potential agent for developing regional community from the bottom-up, driving a people-oriented regional integration approach in southern Africa. The ZCC, with its extensive following among the region’s poor, offers a compelling example of a grassroots and truly bottom-up approach to regional community. This thesis explores the possibility of the ZCC as a model of alternative community and identity centred on people’s daily experiences and grounded in a shared history and solidarity. It seeks to highlight the significance of transnational movements like the ZCC to policy makers in the region and it argues that grassroots communities are marching ahead of SADC member states and politicians in the area of integration. There exists a transnational cooperation amongst followers of the ZCC and other grassroots communities across the region and this cooperation transcends the traditional notion of state sovereignty, thereby highlighting deeper notions of what it means to be a community at regional level.

- Description: This study involves an analysis of accounts of first and subsequent early sexual experiences in a deep rural area of the Eastern Cape in South Africa over the last forty years. Through interviews and focus group discussions, the enculturation of youth into sexual activity in the community of interest is explored. The study looks into sexual experiences from childhood, through early adolescence to adults of up to sixty five years old, allowing an analysis of the changing forms of sexual experimentation and sexual debut in this context. Contextual factors mediating these changes are explored, with special emphasis on the changing regulatory practices around early sexual experiences and the effect thereof on behaviors connected to HIV infection risk. Practices that were previously important mediators of sexual behavior were: anxiety about the social consequences of pregnancy, which was previously a significant disincentive to sexual intercourse; men's previous acceptance of the need to practice non-penetrative forms of sex and girls postponing sexual debut for as long as possible. All these were culturally endorsed, but are now noted to have changed due to changes in the regulatory practices surrounding youth sexuality. The context of early sexual experiences and the surrounding cultural practices have also changed significantly, and this needs to be taken into account in understanding receptivity to condom use messages. Implications for HIV/AIDS prevention are discussed. Among other interventions, the study describes a participatory, community-based, multi-sectoral approach that takes social conditions into account as a way of empowering the community to strengthen its response to the pandemic. This incorporates different sectors of the community, including youth, parents, religious and traditional leaders, and various other structures, services and institutions that make up the community.
