- Description: In 2000, cabinet adopted the South African Policy framework for women’s empowerment and gender equality, 2000 (Policy framework) which provided for the establishment of the National Gender Machinery (NGM). The NGM is a network of coordinated structures within and outside government which operate cooperatively in facilitating political, social, economic and other forms of transformation to dismantle systemic gender inequality and promote equality between women and men. The implementation of gender equality policy as a function area has constitutionally been given to the national and provincial legislatures in South Africa. The constitution allocated this function to the local sphere of government. Camdeboo and Inxuba Yethemba local municipal authorities are the facilitators of sustainable gender equality policies to citizens on behalf of the national and provincial spheres of government. The study was thus conducted within the Camdeboo local municipality and Inxuba Yethemba local municipality. Camdeboo locoal municipality is one of nine local municipalities in Sarah Baartman district municipality. Inxuba Yethemba local municipality is in Chris Hani district municipality. The purpose of the study was to evaluate the implementation of gender equality in the Provision and Utilisation of Women administration Personnel a comparative study of the Camdeboo local municipality and the Inxuba Yethemba local municipality and to determine the impact of the existing policy on the gender equality policy on the needs of women of both municipalities. For this purpose the fundamental and overall study problem was found to be that the gender equality at the Camdeboo and Inxuba Yethemba is hampered by the implementation of an inadequate municipality gender equality policy and by incompetent municipal personnel in particular and in general by the municipality itself. These action do not satisfy the main purpose of the Employment Equity Act no 55 of 1998 to achieve in the workplace by promoting equal opportunity and fair treatment in all forms of employment through elimination of unfair discrimination as well as the implementation of affirmative action measures. The hypothesis was furthermore based on the fact that the existing gender policy of Camdeboo local municipality and Inxuba Yethemba local municipality gender equality policy are inadequate to satisfy women and impacts negatively if not harmfully on human being of women. The study revealed that besides the implementation of gender equality policy by these incompetent municipal personnel, there are economic, social, political and physical effects on women. In case of applications for senior management position, preference is always given to their male counterparts at the expense of equally qualified female applications. Secondly, Gender equality in human resource determination forms part of the processing phase in the system theory. These two municipalities should be made to commit themselves by appending their signatures to all control measures put in place to evaluate the level and the extent of gender equality across all the departments/ sections in the municipality. Any section/ department that implements gender equality more effectively should be identified applauded and given recognition. This would motivate and eliminate gender inequality. Personnel provision and utilization is of paramount importance to every organization. It then becomes extremely necessary to examine the gender equality on human resource determination.

- Description: This study first explored the rate of forest deforestation in Shamva resettlement areas. It then identified and estimated the extent to which these resettled farmers depend on forest for their livelihoods. Evaluation of farmer perceptions on management issues and willingness to participate in indigenous forest conservation and the socio-economic and institutional factors which affect their willingness to participate were also done. Finally the study sought to identify incentives for forests conservation. The study was conducted in Shamva district in Mashonaland Central province. And the respondents were stratified into three groups: A1, A2 and Old resettlement models. The three models differ on how they were implemented and supported which might render them to have different deforestation rates, livelihood strategies and forest dependency. A total of 247 respondents were surveyed, consisting of 98 A1 farmers, 50 A2 farmers and 99 Old resettled farmers. The data was collected using GIS and remote sensing, structured questionnaire interviews and direct observation. The data was analysed using descriptive analysis, KAP analytic framework and binary logistic regression analysis. The land cover/changes results revealed that both deforestation and afforestation are taking place in Shamva resettlement. Woodland and bushland were decreasing, croplands were also decreasing. However woodland dense and grasslands were increasing. Deforestation was found to be as a result of the resettled farmers’ livelihood strategies which were found to be diverse and agriculture being dominant in all models. All the farmers depended on the forest but at varying levels of 19 percent for Old and 14 percent forA1 and 0.02 percent for A2 resettle farmers. 84 percent of the interviewed farmers however, indicated that they are willing to conserve forest with A1 farmers being the highest followed by A2 86 percent and lastly Old resettled farmers at 76.8 percent. Results of the binary regression model revealed that the significant factors which explain willingness to participate in indigenous forest conservation are age, marital status, education, gender, institution, culture and belief, employment and household size. The highest preferred incentive was the provision of free seedlings and the lowest was out grower scheme. The study recommends that GIS and remote sensing should be used to monitor deforestation, off farm projects be encouraged, exotic and indigenous trees be promoted and forest conservation education be promoted in resettlement areas.

- Description: The construction sector serves as the engine of growth to the South Africa economy because of its catalytic role in the growth and development of the country. This study focuses mainly on the influence of the macro-economic environment on the contribution of the private sector to construction in the South Africa economy from 1984 to 2011. Government construction work is considered to be an injection into the economy; in this regard, state construction is regarded as public investment in the economy; and therefore, it is anti-cyclic (Keynes, 1936). The aim of this study has been to develop an econometric model for predicting the influence of the macroeconomic environment on the contribution of the private sector to the construction sector in the South Africa economy. The research design adopted in this study was an “ex-post facto” type, otherwise known as a causal-comparative design. The data were extracted from the published sources of the South African National Statistics, namely SARB, Stats SA and Quantec SA. The estimation technique used in this study was the ARDL model using quarterly data from 1984 to 2011. This is because in the construction sector, the influence of the independent variables is always felt over time – rather than all at once. The results of this study show that there is a long run causal relationship between inflation rate, interest rate, real exchange rate, GDP and gdp in the construction sector. The descriptive statistical analysis shows that there is a negative relationship between variables inflation rate and interest rate and the private sector spending in construction. However, economic growth as well as growth in the construction sector has a positive relationship with the private sector spending in construction. Likewise, the real exchange rate and labour productivity in construction have a negative relationship with the private sector’s spending in construction and they are statistically insignificant. The variance decomposition analysis show that the private sector spending in construction explains about 75 per cent of it variations, followed by inflation rate that explains 21 per cent on the average; while the remaining variations, comprising about 4 per cent, were shared among the other independent variables, such as GDP, GDP in construction, the interest rate and the real exchange rate. It was discovered that only the inflation rate does Granger-cause the private sector spending in construction. From the finding it can be concluded that inflation rate is a significant explanatory variable in explaining the variation in the dependent variable during period under review. Policy recommendations are as follows: firstly, the monetary authorities in South Africa should embark on sound policies that would bring about low prices of the construction materials. This would ensure growth and development in the construction sector; secondly, a stimulating development plan that would encourage private sector investment in properties and infrastructural development must be instituted; thirdly, an alternative policy to the present inflation targeting is recommended that would bring about low inflation, high growth, low unemployment and stable exchange rate; fourthly, the present policy on interest rate must be reviewed to allow for more participation in construction projects by the private sectors of the economy; fifthly, due to the fact that fluctuation in the crude oil prices in the international market is one of the major factors causing high inflation rate in South Africa, government must source local alternative products that would bring down prices of construction materials.

- Description: This thesis explores whether or not it is possible to positively inflect – via digital means – people’s orientations toward nature through connecting their duration to the time of animals. The thesis opens with an overview of the contemporary environmental crisis, mapping related significant discourses, events and responses from the early 1960s onward. In this regard, after thematizing the relatively ineffective global institutional response to the environmental crisis to date – in spite of both consistent criticisms proffered by a range of stakeholders and widely available information on the scope of current environmental degradation – the lack of any concerted effort to deal with this issue is accounted for in terms of the dimensions of what Kilbourne, Beckmann and Thelen refer to as the ‘Dominant Social Paradigm’ (DSP). However, it is argued that of these dimensions, the technological dimension is most amenable to pro-environmental inflection, particularly through recent developments within information technology. That is, despite the latter being the privileged technology of neoliberalism, and despite the environmental cost of its current material infrastructure, it is also highly unlikely that societies will abandon their dependence on information technology in the near future. Given this, the importance of considering how such technology can be harnessed to positively re-orientate users’ perceptions of the natural world, in a way that also avoids the pitfall of technophilia, is advanced. In terms of this, both positive and negative appraisals of information technology by prominent new media theorists are discussed, and information technology is put forward as a tool that remains indeterminate in terms of its use. After this, and with a view to exploring how the technological dimension of the DSP might possibly be inflected in a pro-environmental manner, the thesis draws on the works of Gilles Deleuze and Félix Guattari who promote desire and difference outside the ambit of capitalism, particularly through desubjectivation in relation to their concept of ‘becoming-animal.’ Finally, after dealing in addition with some potential theoretical challenges to the application of Deleuze’s ideas within the digital realm, focus shifts to three contemporary digital artefacts which have the capacity, albeit to varying degrees, to facilitate a becoming-animal. In this regard, a distinction is made between those artefacts that precipitate first-, second- and third-order hybrid durationality, and it is argued that the latter category presents the greatest promise of interfacing the time of humans with the time of animals.

- Description: While wastage of materials has become a serious problem requiring urgent attention in the Nigerian Construction Industry, cost overrun is a problem, which affects 90 percent of the completed projects in the world; the argument on how to reduce/eliminate cost overrun has been on-going for the past 70 years; as the on-site wastage of materials leads to increases in the final project cost. Studies from different parts of the world have shown that construction-material waste represents a relatively large percentage of the production costs. Consequently, as a result of low levels of awareness, the Nigerian construction industry pays little attention to the effects of generated material waste on cost overruns. Thus, this research aimed to investigate the relationship between material waste and cost overrun in the Nigerian construction industry. A comprehensive review of the related literature revealed that all material waste causes are related to cost overrun causes at both pre-contract and post-contract stages of a project; but not vice versa. The mixed method (quantitative and qualitative) approach that is rooted in the positivist paradigm was adopted for this study. Abuja, the federal capital territory of Nigeria was the selected geographical scope of this research, out of which thirty-one (31) construction projects were purposeful selected (projects to the value of 100 million Rand/1.6 billion Naira and above).The research instrument was an interview guide used in conjunction with a tick box. Other sources of data included field investigation (measurement of onsite material waste) and the collection of archival records from bills of quantities, project records, and specifications. Analyses of the findings lead to the conclusion that a relationship exists between material waste and cost overrun; at the pre-contract and at the post-contract stages of a project. The implication is that an increase in material wastage on-site leads to a corresponding increase in the amount of cost overrun, regardless of the percentage allowance for material waste in the process of bill preparation. The study also concluded that the average percentage contribution of material waste to project-cost overruns is four (4) percent. Material-waste sources, causes, and control measures were found to have significant effects (very high, high, medium, low, and very low), in causing or minimising cost overruns at both pre-contract and post-contract stages of projects. The research has developed a conceptual model for the management of material waste and cost overruns in the construction industry based on the results and informed by the theoretical framework. The research has also developed a mathematical model for quantifying the amount of material waste to be generated by a project; as well as a mathematical equation for the effective management of material waste and cost overrun for projects. The study has achieved its aim of establishing an understanding of the issues leading to the relationship between material waste and cost overruns, as well as their management in the Nigerian construction industry. The study recommends that the management of material waste and cost overrun should be revised, based on the findings of this research and included as part of the procurement process. The mathematical models for quantification of onsite material waste, and the mathematical equation for managing material waste and cost overruns developed in the study, could be usefully adopted to improve management of material waste and cost overrun in the Nigerian construction industry.

- Description: While wastage of materials has become a serious problem requiring urgent attention in the Nigerian Construction Industry, cost overrun is a problem, which affects 90 percent of the completed projects in the world; the argument on how to reduce/eliminate cost overrun has been on-going for the past 70 years; as the on-site wastage of materials leads to increases in the final project cost. Studies from different parts of the world have shown that construction-material waste represents a relatively large percentage of the production costs. Consequently, as a result of low levels of awareness, the Nigerian construction industry pays little attention to the effects of generated material waste on cost overruns. Thus, this research aimed to investigate the relationship between material waste and cost overrun in the Nigerian construction industry. A comprehensive review of the related literature revealed that all material waste causes are related to cost overrun causes at both pre-contract and post-contract stages of a project; but not vice versa. The mixed method (quantitative and qualitative) approach that is rooted in the positivist paradigm was adopted for this study. Abuja, the federal capital territory of Nigeria was the selected geographical scope of this research, out of which thirty-one (31) construction projects were purposeful selected (projects to the value of 100 million Rand/1.6 billion Naira and above).The research instrument was an interview guide used in conjunction with a tick box. Other sources of data included field investigation (measurement of onsite material waste) and the collection of archival records from bills of quantities, project records, and specifications. Analyses of the findings lead to the conclusion that a relationship exists between material waste and cost overrun; at the pre-contract and at the post-contract stages of a project. The implication is that an increase in material wastage on-site leads to a corresponding increase in the amount of cost overrun, regardless of the percentage allowance for material waste in the process of bill preparation. The study also concluded that the average percentage contribution of material waste to project-cost overruns is four (4) percent. Material-waste sources, causes, and control measures were found to have significant effects (very high, high, medium, low, and very low), in causing or minimising cost overruns at both pre-contract and post-contract stages of projects. The research has developed a conceptual model for the management of material waste and cost overruns in the construction industry based on the results and informed by the theoretical framework. The research has also developed a mathematical model for quantifying the amount of material waste to be generated by a project; as well as a mathematical equation for the effective management of material waste and cost overrun for projects. The study has achieved its aim of establishing an understanding of the issues leading to the relationship between material waste and cost overruns, as well as their management in the Nigerian construction industry. The study recommends that the management of material waste and cost overrun should be revised, based on the findings of this research and included as part of the procurement process. The mathematical models for quantification of onsite material waste, and the mathematical equation for managing material waste and cost overruns developed in the study, could be usefully adopted to improve management of material waste and cost overrun in the Nigerian construction industry.

- Description: AIDS is one of the most destructive diseases humankind has ever faced and also brings with it profound social, economic and public health consequences, making it one of the most serious health and development challenges in the world today. Zimbabwe, situated in southeastern Africa, is not spared from the pandemic. It continues to be one of the Sub-SaharanAfrican countries mostly heavily impacted by the AIDS epidemic, with almost 1.2 million people infected and over 1.1 million orphans. It ranks, therefore, as fifth highest in the world in the impact HIV and AIDS has had on the country. The most effective response has been to introduce programmes to reduce the number of new infections. Recent research has demonstrated treatment as a preventative measure to be very effective. This approach involves targeting those who are infected so that they are not able to transmit the disease. The decision that has to be made by an infected person, however, is whether to look for traditional treatment, conventional treatment or a combination of the two. Herbal medicine use is becoming very common in many countries, especially in the developing world, where public health safety has become a concern. It has become common to use herbal medicine concomitantly with allopathic or conventional medicine. The present study focused on investigating perceptions leading to the choice of treatment with the traditional alternative medicines (TAM) as (a)/n alternative or compliment to the conventional or allopathic option. This is a qualitative study that explores and describes participant’s perceptions, beliefs, attitudes and feelings around the use of traditional medicine, within the context of the Integrative Behaviour Model (IBM). Data was collected from 20 people living with HIV and AIDS from urban and rural settings of different ethnicities (Shona and Shangani). The data analysis was informed by The Interpretive Phenomenological Analysis with the aid of NVivo (V.10), a computer-assisted Qualitative Data Analysis Software. As predicted by the IBM, both perceived individual and environmental factors were found to be key in influencing decision-making on the use of TAM by people living with HIV and AIDS. Although there were a number of incidents in which either individual or environmental factors were perceived as independently influencing the TAM-use decision-making process, there was a lot of mutual influence between the environment and the individual. Such mutual causation was abstracted as reciprocal determinism. The IMB model assumed a unidirectional causation in which the environment could affect the individual factors. While the present study identified and demonstrated these environmental effects on the individual, it also identified and presented a reverse causation in which the individual would also affect the environment with respect to motivation for TAM use. Individual factors were psychological properties that drove the individual to use TAM. Attitude, social influence and personal agency emerged as the three dimensions of individual factors. Attitudes helped in identification of orientations that located objects of thought on dimensions of judgment about the use of TAM. Social influence explained social pressure experienced and expected regarding the use of TAM. The study demonstrated the importance of both the descriptive and injunctive norm with participants indicating that they perceived important others to be using traditional medicine and that they felt perceived expectations from others to do the same and hence the motivation to comply. Personal agency pointed to the participants’ capacities to originate and direct actions for the purposes of TAM use. All these constructs were found to be very important as perceived determinants of the behavioral intentions of people living with HIV and AIDS to use traditional medicines. In experiential attitude, generally the respondents showed more perceived positive evaluations of pleasurable experiences in their use of traditional medicines. However, there were other outcome evaluations that seemed to be ambivalent and which appeared to cause a lot of tension. The comprehension of experiential attitude was found therefore found to be trichotomous rather than dichotomous as per the IBM. The effects of the instrumental attitude were revealed in the ratings of the extent to which the use of traditional medicine was perceived as useful or rewarding, with the study revealing high ratings of usefulness. It becomes clear, therefore, that for people living with HIV and AIDS social influence, perceived attitudes and personal agency are important decision-making factors in their use of traditional and alternative medicine. Efforts towards education, integration and behaviour change programmes should design messages targeting these behavioral determinants. Understanding of these perceived determinants is crucial to influencing policy as well as the adoption of health practices through education, marketing and other modes of health promotion.

- Description: This thesis investigated the physical properties of the macrolide antibiotics: Erythromycin dihydrate (EM-DH), Roxithromycin monohydrate (RM-MH) and Azithromycin dihydrate (AZM-DH). The abovementioned hydrate compounds were investigated in terms of the hydrate-anhydrate crystal structure stability, dehydration and observed polymorphism under controlled temperature heating programs. Identified hydrate and anhydrate polymorphs were subjected to physical stability testing during controlled storage. EM-DH was characterized by thermal analysis (DSC, TGA), X-ray diffraction, FTIR and microscopy. Dehydration of EM-DH at temperatures of 100, 157 and 200°C (followed by supercooling to 25°C) produced the form (I) anhydrate (Tm =142.9°C), form (II) anhydrate (Tm = 184.7°C ) and amorph (II) (Tg = 118°C) respectively. The attempts to produce amorph (I) from melting (in vicinity of form (I) melt over temperature range 133°C to 144°C) and supercooling was unsuccessful due to the high crystallization tendency of the form (I) melt. Brief humidity exposure and controlled temperature (40°C)/ humidity storage for 4 days (0-96% RH) revealed hygroscopic behaviour for the anhydrate crystal (forms (I) and (II)) and amorph (II) forms. Form (II) converted to a nonstoichiometric hydrate where extent of water vapour absorption increased with increased storage humidity (2.1% absorbed moisture from recorded TGA at 96% RH). Amorph (II) exhibited similar trends but with greater water absorption of 4.7% (recorded with TGA) at 96% RH. The pulverization and sieving process of amorph (II) (at normal environmental conditions) was accompanied by some water vapour absorption (1.1%). A slightly lower absorbed moisture content of 3.3% (from TGA) after controlled 4 days storage at 40°C/ 96% RH was recorded. This suggested some physical instability (crystallization tendency) of amorph (II) after pulverization. The thermally induced dehydration of RM-MH by DSC-TG was evaluated structurally (SCXRD), morphologically (microscopy) and by kinetic analysis. Various kinetic analysis approaches were employed (advanced, approximation based integral and differential kinetic analysis methods) in order to obtain reliable dehydration kinetic parameters. The crystal structure was little affected by dehydration as most H-bonds were intramolecular and not integral to the crystal structure stability. Kinetic parameters from thermally stimulated dehydration indicated a multidimensional diffusion based mechanism, due to the escape of water from interlinked voids in crystal. The hygroscopicity of the forms RM-MH, Roxithromycin-anhydrate and amorph glass (Tg = 81.4°C) were investigated. Roxithromycinanhydrate (crystalline) converted readily to RM-MH which were found to be compositionally stable over the humidity range 43-96%RH. Amorphous glass exhibited increased water vapour absorption with increasing storage humidity (40°C/ 0-96% RH). TG analysis suggested a moisture content of 3.5% at 96% RH after 4 storage days. DSC and powder XRD analysis of stored pulverised amorphous glass indicated some physical instability due to water induced crystallization. Commercial AZM-DH and its modifications were characterized by thermal analysis (DSC, TGA), SC-XRD and microscopy. Thermally stimulated dehydration of AZM-DH occurred in a two-step process over different temperature ranges. This was attributed to different bonding environments for coordinated waters which were also verified from the crystal structure. Dehydration activation energies for thermally stimulated dehydration were however similar for both loss steps. This was attributed to similarities in the mode of H- bonding. Different forms of AZM were prepared by programmed temperature heating and cooling of AZM-DH. The prepared forms included amorphous glass (melt supercooling), amorphous powder (prepared below crystalline melting temperature), crystalline anhydrate and crystalline partial dehydrate. Humidity exposure indicated hygroscopic behaviour for the amorphous, crystalline anhydrate and crystalline partial dehydrate modifications. Both the crystalline anhydrate and partial dehydrate modifications converted to the stoichiometric dihydrate form (AZM-DH) at normal environmental conditions at ambient temperature. Both the amorph glass and amorph powder exhibited increased moisture absorption with increased humidity exposure. TG analysis of the pulverised amorph glass indicated a moisture content of 5.1% at 96% RH after 4 storage days. The absence of crystalline melt in DSC and presence of Tg (106.9°C) indicated the sample remained amorphous after pulverisation and storage for 4 days at 40°C/ 96% RH.

- Description: Unwanted early sexual experiences (UESE) are traumatic experiences that many children worldwide are exposed to on a daily basis. Some of these victims struggle to adapt to life, whereas others become survivors, exhibiting post-traumatic growth after such an experience. South Africa has some of the highest UESE prevalence rates in the world, highlighting the importance of research conducted within this field in the country. With an overarching psychofortogenic framework, and through the implementation of a convergent parallel mixed methods research design, the study explored and described whether resilience and attachment act as mediators impacting upon the psychosocial sequelae which a UESE survivor might experience. The study was divided into three phases. Phase 1 consisted of a small-scale survey design which was conducted with 304 participants while Phase 2 consisted of nine semi-structure interviews with UESE survivors, who were volunteers from the original sample. Finally, Phase 3 provided an integrated summary of the findings from the first two phases. During Phase 1 significant findings relating to the survivors of UESE, their levels of resilience and attachment relationships were outlined. Of the total sample, 32.43% males and 30.5% females indicated that they had been exposed to a UESE. Most of the perpetrators were known to the survivors with friends being identified as the most common perpetrators. Parental relationships characterised by trust, open communication and less alienation were found to impact upon the degree to which participants reported being bothered by the UESE. Furthermore, parental alienation at the time of the UESE had a significantly negative impact on the survivors’ adult relationship styles. During Phase 2 a number of themes emerged including the manner of disclosure, reasons for delayed disclosure, relationship to the confidant, confidant’s response to disclosure, effects of the response to disclosure, the impact of the UESE upon the survivor, impact of the UESE on relationships, coping/resilience, advice to professionals, the confidant, and the survivor. The final phase confirmed the research hypothesis that resilience and attachment act as mediating factors impacting upon a variety of psychosocial sequelae which a UESE survivor might experience. Serendipitously, disclosure was found to be a mediating factor, securing a significant role within the study. In conclusion a future intervention titled ‘Post-Traumatic Growth: A UESE model of Disclosure, Resilience and Attachment’, was outlined, based on the study’s findings.

- Description: Sustainability reporting is becoming increasingly important, and governments and stock exchanges of many countries require or strongly encourage businesses to provide some level of sustainability reporting. South Africa is one of few emerging market economies and the only country in Africa which show substantial sustainability reporting activities. In South Africa, sustainable development has been recognised at a constitutional and legislative level. Companies listed on the Johannesburg Stock Exchange (JSE) must integrate sustainability reporting with financial reporting, or explain why they are not complying. Establishing a suitable sustainability reporting framework should therefore be part of the strategic integration of sustainability with other aspects of organisational planning and decision-making. This study suggests such a framework of standards and indicators for sustainability reporting in South African businesses, and evaluates it in South African listed companies. Mixed methods research was used in two phases. In phase 1, a critical analysis of the literature produced a framework of standards and indicators to be used as a measure to evaluate sustainability reporting in South Africa. In phase 2, first hand, original data was collected by performing a quantitative content analysis of sustainability reports of 84 companies listed on the Johannesburg stock exchange with the aim to identify standards and indicators that are applied in the content of sustainability reports in South Africa. Quantitative content analysis involves analysing material and then classifying it into various coding units or themes found in the material - it is a systematic way of converting text to numerical variables for quantitative data analysis.

- Description: People living with HIV and AIDS (PLHIV) suffer from a number of stress-related psychological disorders. The aim of this study was to develop an integrative intervention, which combined Cognitive Behaviour Therapy (CBT), Body-Mind Therapy and Multicultural perspectives to assist health care workers in identifying and treating stressrelated psychological disorders among people living with HIV and AIDS. The study employed an intervention research design using both qualitative and quantitative methods. The quantitative data was collected from PLHIV attending HIV Counselling and Testing (HCT) and Anti-retroviral therapy clinics in the Buffalo City Municipality (BCM) of the Eastern Cape Province. The qualitative data was collected from the health care workers of the selected study sites. Purposive sampling was used to select the study sample. Instruments used included a biographical questionnaire, the Beck Depression Inventory-II (BDI-II), Medical Outcome Study- HIV (MOS-HIV) and focus group interviews to gather data for the development of an intervention model that would address reported stress-related psychological disorders. Findings showed that people living with HIV and AIDS endure stress in their lives on daily basis rather than episodes of severe or clinical depression. Many of the PLHIV are dealing with a number of psychosocial problems that compromise their quality of life and health status. In conclusion, the study illustratively interpreted and discussed the results in relation to the objectives of the study. The study recommends that PLHIV should be exposed to stress management programmes, and health care workers (HCWs) should be offered training in basic counselling skills, stress management and/or debriefing.

In conclusion, the study illustratively interpreted and discussed the results in relation to the objectives of the study. The study recommends that PLHIV should be exposed to stress management programmes, and health care workers (HCWs) should be offered training in basic counselling skills, stress management and/or debriefing.

- Description: It is widely believed that Acacia karroo Hayne trees compete with and negatively affect the production of grasses in their immediate surroundings. This perception formed as a result of observations by farmers of their veld as well as some research. The complexity of plant interactions in different conditions required that research be done to better explain the extent of grass and tree interactions. In response to this need, the effect of a range of Acacia karroo densities on grass production was tested in areas of differing rainfall. Results emphasize the complexity of such plant interactions but highlight rainfall as influencing the effect of tree density on grass production and grass quality. Study sites were chosen with significant differences in tree density and rainfall and this was found to be concomitant with significant differences in grass yield and crude protein (p < 0.001). Grass yield (mass produced) was negatively correlated with tree density (p < 0.001) and was affected by rainfall. High tree density reduced grass yield at the lower rainfall sites, but a reduction in yield was only recorded during dry conditions in the higher rainfall areas. By contrast, the crude protein content of grasses was positively correlated to tree density (p < 0.001). However, as with yield, rainfall played an important part in the strength of the correlation. Soil properties such as temperature (-) (p = 0.011), phosphorus content (+) (p = 0.006), calcium concentration (+) (p = 0.005), acid saturation (-) (p = 0.018), and soil pH (+) (p = 0.008) were also significantly correlated to tree density. Tree density enriched the soil, subsequently benefitting grass quality. The study sites investigated, had different plant communities and environmental conditions with Cradock, Kubusi Drift and Kei Mouth having unique communities and conditions while Adelaide and Cathcart could not be separated in either. Cradock was the driest site and the vegetation was dominated by both grasses and karroid shrubs, differing in pattern and process from the other sites. The Kubusi Drift site had high tree densities, to the extent that the trees altered the grass species composition. The effects of rainfall on grass yield and quality exceeded that of community composition differences.

- Description: This study investigated the influence of decentralisation on community development in the Gasabo district of Rwanda. It was based on the assumption that the participation of citizens in decision-making, planning based on local needs and priorities and the implementation of development programmes associated with the decentralisation policy can improve service delivery and result in community development. It is vital that the decentralization policy be well understood so that appropriate strategies may be adopted and implemented with the aim of maximising advantages associated with it. This study provides, in addition to a literature review, a brief historical background of the evolution and transformation of governance in Rwanda. The country‟s system of governance as well as the challenges it has encountered along the way through different régimes are briefly addressed. Also, the legal and regulatory framework of the decentralization policy and strategies adopted and mechanisms of resource transfer are explained. The study used both qualitative and quantitative methods. Primary and secondary data were used in analysing the influence of decentralisation on community development in the Gasabo district of Rwanda. Primary data was collected through survey questionnaires, interviews and focus group discussions, while secondary data were gathered through a literature survey of relevant textbooks, peer-reviewed journals, reports and legislation. The research findings indicated that in the Gasabo district, decentralisation has contributed significantly towards improving governance aspects such as accountability, and citizen participation in development programmes, which are prerequisite factors of development. Concerning the planning process, the research found that the district development plan (DDP) was crafted through drawing its priorities from the national development plans embedded in the Economic Development and Poverty Reduction Strategies (EDPRS) and Rwanda‟s Vision 2020. However, despite the existence of the Joint Action Development Forum (JADF), created to join the development plans of development partners to the DDP, testimonies from development partners revealed that their relationship with the district is characterised by the lack of frank collaboration, leading to their not being fully associated in the planning process. This research also found that the decentralisation policy has contributed only to a limited extent to the improvement of service delivery in Gasabo district. It was observed that effective service delivery is still hampered by the lack of skilled employees, especially in the areas of education, health and engineering, a budget insufficient for the effective implementation of development projects in such a way as to satisfy the expectations of beneficiaries. In view of the aforementioned findings, the study recommends that the central government intervene in training district tax officers regarding mechanisms and strategies of maximising tax collection to draw sufficient funds to carry out development plans. Through building their capacity, the imbalance between the responsibilities and means allocated for carrying out their achievement can be progressively reduced. Furthermore, to prevent development from taking place in a random manner, district authorities should receive technical support from the central government through linking the local planning process to national poverty reduction efforts. The annual performance contract system needs to be strengthened and monitored to evaluate the implementation of district development plans so as to prevent any kind of poor leadership performance, with the aim of optimising available resources.

- Description: Adventure tourism (AT) is a rapidly growing subsector of the tourism industry. With the recent increase in AT, the nature of the industry is undergoing major changes. Originally a small and relatively specialized sector of tourism, AT is now expanding to include ommercialized and larger scale operations. This creates a need to re-evaluate the AT industry in the context of these new, highly commercialized and often “manufactured” adventure experiences. Although there are many definitions and conceptualizations of what onstitutes AT, it is most often referred to as tourism experiences that involve some element of risk and typically take place in outdoor natural environments. Inherent in the definition of AT is the natural environment, however very little research has focused on the role of the environment in AT. The interaction between humans and the environment is one of the most fundamental relationships of human existence. Within this context, existing research largely focuses on the influence of humans on the environment. However, it is important to also understand how the environment influences human behaviour. This thesis, therefore, seeks to examine the influence of the environment on humans in the AT context. It does so by analyzing three primary aspects of human-environment interaction in AT participation. The first is participants’ ‘value system’including their general perspectives of the environment and previous experience with AT. The second focuses on the relative strength and nature of environmental influences on AT motivations. The final aspect delves into the role of the environment in enhancing AT experiences and satisfaction. These assessments were done by analyzing questionnaires collected from participants in eight commercial AT operations along the Cape South Coast of South Africa. Data was primarily based on responses to statements using a 5 point Likert Scale. The responses were analyzed and discussions utilized results based on descriptive statistics, significance levels based on onesample t-tests, frequency distributions and analysis of variance (ANOVAs) which divided the data based on activity type. In addition Pearson’s Product Moment Correlations were conducted to assess linkages between different components of the thesis. The results that emerged from this thesis show that the environment plays an important role in AT participation. The value system of commercial AT participants demonstrated a level of general experience with AT as well as moderate environmental values. The strength of the environment in the motivations to participate in AT emerged quite substantially. Reflective interactions with nature (i.e. learning about the environment, and appreciating nature’s beauty) were found to be amongst the most significant internal motivation factors for participation. Interestingly, although the vast majority of research focuses on the Risk/Thrill element of AT motivations, it was not found to be an important motivation factor amongst the vast majority of AT participants. The environmental aspects of the destination were found to be, by far, the most significant external motivation factor, implying that the selection of destination for AT participation is largely based on the environment in which the activity takes place. Participants were also found to have strong, positive emotional experiences as a result of AT participation,which were significantly enhanced by the environment in which the activities took place. In addition, as a result of these positive experiences, emotionally and with the environment, participants were highly satisfied with the AT experiences. The culmination of the results discussed above was the development of a modified, empirically-tested framework for human-environment interaction in the AT context. The final framework demonstrated links between various components of human-environment interaction. Strong links were found between motivations, experiences and satisfaction while relatively weak links were found between the value system of participants and their subsequent motivations. The framework was developed for the possibility of applying it to other contexts. The findings in this thesis demonstrate that the environment does, in fact, play an important role in the interaction between humans and the environment in AT. They emphasize the relatively significant influence that the environment has on the motivations and experiences of AT participants.

The relationship between language and xenophobia: a developmental perspective

- Description: Modernisation, globalisation, neoliberalism and the increase in immigration have morphed into xenophobia, as they have resulted in structures that increased inequalities and competition for scarce resources, although there are other factors such as the global recession that is deepening inequalities and social classes. In South Africa, xenophobia is a topical matter, with chronic violent outbursts. The study addresses the gap in knowledge in the relationship between language and xenophobia. Language is central to human communication and to human socialisation and is not neutral but is embedded in ideologies that favour specific interest groups. The neoliberal ideology compels people as human capital to develop linguistic capital. The paradox is that globalisation transcends the national to transnational, while at the same time being conscious of the local or the indigenous language. Globalisation promotes hybridity and diversity, while at the same time promoting homogeneity or Westernisation, which is contrary to the nationalist ideology to protect the cultural heritage of the locals. This thesis is guided by a range of classical and more contemporary development theories. It includes the use of Marxist theory with regard to ownership and unequal distribution of resources. The culture of violence that manifests in xenophobia in South Africa can also be related to the violence of the colonial and apartheid periods. This thesis is also guided by the post-colonial theory. It also looks at theories of modernity and of globalisation, suggesting that a truly ‘modern’ society should be transformed in all spheres and should value multifaceted human well-being (and not only in terms of economic ‘growth’). A primary objective of this study is to explore the role of language in social institutions such as education in order to understand how matters of language exacerbate xenophobia and to document the challenges related to language that ‘foreigners’ from other parts of Africa face in South Africa. Questions asked include whether they can survive/thrive without knowledge of local languages, whether they are victims of crime because they cannot speak the local languages and whether and how they are being assimilated into South African society. This research therefore, recommends that language planning in South Africa should maintain a balance in the use of the English language as a lingua franca and the use of the indigenous languages so as to avoid the language endangerment of the indigenous languages and monolingualism, as well as subtractive bilingualism. This research is against institutional discrimination of foreigners by use of language as a gate keeper or an entry fee into the higher domains. The results of this research lead to the recommendation on language planning that leads to economic opportunity, higher economic productivity, educational development, enrichment in the sense of creativity innovation, cognitive flexibility, and more effective social integration, while restoring citizens’ sense of self-worth and their experience of emotional and social security, and also promoting social integrity and nation-building. Good language planning should be a crucial aspect of development planning. This research contributes to the field of Development Studies in that it analyses the conflicting issues within language and xenophobia in South Africa, while using the complexity theory to restore a modernised society with modern values that are not xenophobic but open to the global society. It also contributes to the politics of culture by keeping a balance between the endogenous culture versus the exogenous culture; a localised culture versus a globalised culture.

The role of apex predators in ecosystem function: fear triggered cascades regulated by differential prey vulnerability

- Description: Trophic cascades involving large terrestrial mammals are very seldom empirically demonstrated. The high species diversity often associated with terrestrial systems is thought to modulate the strength of trophic cascades. In speciose systems, species often vary in vulnerability to consumption, hence some species are less responsive to top-down pressure. African large mammalian herbivores are highly diverse and vary greatly in body size, a characteristic linked to vulnerability to predation. Moreover, Africa is one of the last places to still support megaherbivores, species that have grown large enough to be practically impervious to non-human predation. Thus an African ecosystem is the ideal setting to explore trophic cascades in speciose terrestrial systems. In this study I explored patterns in trophic interaction amongst carnivores, vulnerable mesoherbivore and predator-invulnerable megaherbivores in an intact African savanna at a variety of spatial scales. I examined the mechanistic links between trophic levels at the patch scale through fine scale empirical manipulation of predation risk. In addition, I assessed the landscape scale biological relevance of these trophic interactions through correlative observations over large spatiotemporal scales. I present the first evidence of community level trophic cascades explicitly involving megaherbivores. I demonstrate how megaherbivores’ disregard of predation risk masks the effects of predator-triggered trophic cascades and weakens their impact on the ecosystem. The risk of predation triggered a spatial response in vulnerable species, driving them into safe areas, yet did not influence the space use of megaherbivores. This species-specific spatial response had contrasting effects on nutrient distribution. Vulnerable herbivores’ fear-induced foraging behaviour led to localised nutrient accumulation whereas the foraging behaviour of predator-invulnerable megaherbivores led to nutrient redistribution across the landscape. In addition, the fear-driven spatial differences in mesoherbivore grazing impact and nutrient deposition led to landscape scale changes in the distribution and persistence of herbivore maintained grass communities, so-called grazing lawns. However, the grazing activity of the in-vulnerable megagrazer, white rhino (Ceratotherium simum) weakened the effect of this trophic cascade by creating and maintaining grazing lawns within the risky habitat avoided by mesograzers. This study contributes to our understanding of what drives the variation among patterns of trophic control and provides the first evidence of the modulating influence that megaherbivores have on predator-triggered trophic cascades.

- Description: Parental divorce is considered one of the most stressful events in the lives of children. The adult perspective has dominated the discourse on divorce, and only recently has research started to consider the viewpoint of children. Research indicates that the nature of the divorce process as experienced by the child is the most important factor in post-divorce adjustment. It also remains a relatively unexplored area, with research on the manner in which children experience the divorce process being limited. The current study aimed to conduct a narrative inquiry into the experiences and perceptions of parental divorce, of a purposive sample of 9 to 10 year old children. The primary aim of the study was to highlight and honour the voice of the child in a parental divorce process. The current research was qualitative in nature and adopted a narrative paradigm. Five children were interviewed qualitatively using an unstructured interview. Data were analysed using thematic analysis. Seven themes were identified. The first theme explored children’s endeavours to describe and explain parental divorce. An additional six themes were developed around the types of stories children told of the divorce process. Themes included, What is a Divorcement, Stories of Loss, Stories of Gain, Stories of Change, Stories of Stability, Healing Stories, and Complicating Stories. This study endeavoured to provide divorced parents and those working with children a greater understanding of the way in which children perceive parental divorce, and insight into the factors that facilitate children’s positive adjustment to parental divorce.

Five children were interviewed qualitatively using an unstructured interview. Data were analysed using thematic analysis. Seven themes were identified. The first theme explored children’s endeavours to describe and explain parental divorce. An additional six themes were developed around the types of stories children told of the divorce process. Themes included, What is a Divorcement, Stories of Loss, Stories of Gain, Stories of Change, Stories of Stability, Healing Stories, and Complicating Stories. This study endeavoured to provide divorced parents and those working with children a greater understanding of the way in which children perceive parental divorce, and insight into the factors that facilitate children’s positive adjustment to parental divorce.

- Description: Housing is a complex subject and has stimulated thought processes of scholars globally for a long time. Throughout the world, governments are flooded by a myriad of housing challenges associated with the provision of housing. Policy has been used as a communicator of governments’ visions and strategies on housing provision. The apartheid legacies have left the country’s housing terrain totally disfigured. To correct this travesty of justice, the government has resorted to policy and legislative framework. In 1994, the Housing White Paper on housing was introduced as a guiding vehicle of the state’s aspirations in its quest to address spatial inequalities and provide housing to millions who had never had a place they could call home. However, the inability of the programme, to mitigate a successful provision of sustainable housing, motivated the government to rethink its strategy. Thus, a new approach to housing called, “Breaking New Ground” (BNG, 2004) was launched. Contrary to the old housing approach that focussed on mass delivery, BNG would regard quality and spatial reconfiguration and social-cohesion as vital to the realization of sustainable human settlements. Few years after its introduction, the new housing approach had its own share of challenges. The main aim of this investigation was to critically review the state of low-cost housing programme by establishing whether the 2004 policy revision of the national housing programme has had any significant effect on the low-cost housing programme in the country by assessing some of the recent projects initiated under the ambit of the BNG. Through a multi-case study, the researcher has qualitatively investigated the research question. A multi-data gathering approach, consisting of both qualitative and quantitative data-collection instruments such as open-ended interviews, questionnaires and observations, helped the researcher to answer the questions posed by the study. From the investigation, a blend of successes and failures has been noted. It is undeniable that the low-cost housing programme is still inundated with challenges right under the domain of BNG. It is also irrefutable that many positives on the current and recent low-cost housing projects initiated under BNG can be seen.

- Description: The governance of data assets has become a topical issue in the public sector. Government departments are faced with increasingly complex data and information arising from multiple projects, different departments, divisions and several stakeholders seeking data for divergent end uses. However, an exploratory study of the literature regarding data governance in government departments of the Eastern Cape province of South Africa suggest that there are no clear data governance processes in place within the departments. The research question “How can a data governance maturity evaluation model enhance data governance processes in the Eastern Cape government departments” was derived as a result of a perceived need for government departments of the province to manage their critical data assets in a manner which promotes accurate, verifiable and relevant fiscal and strategic planning. Following the review of current literature in the data governance domain, a conceptual data governance evaluation maturity model was developed and produced. The conceptual model was influenced by the IBM data governance maturity model (2007) and it was aimed at addressing the gaps in the reference model to suit the context of the Eastern Cape government departments and the governance of their data assets. A qualitative phase of empirical data collection was conducted to test the components of the conceptual model. A quantitative instrument, derived from the findings of the qualitative study, as well as the components of the refined model was administered to 50 participants in the same departments where qualitative data was collected, with additional participants being drawn from three other departments. Pragmatism was the guiding philosophy for the research. The Contingency and Institutional theories form the theoretical grounding for the study. Design Science guidelines by Hevner et al (2004), Peffers et al’s (2008) Six Steps in Design Science and Drechsler & Hevner’s (2016) Fourth Cycle of Design Science were employed to construct, improve, validate and evaluate the final artefact. Findings confirmed the literature that data governance is lacking in government departments. It is asserted that the implementation of this model will improve the way data assets are recorded, used, archived and disposed in government departments of the Eastern Cape. The outcome of this research was the development and production of a data governance maturity evaluation model as well as a process document which gives a roadmap of how to move from one maturity level to another.

A framework for enhancing the effectiveness of strategic leadership in the Eastern Cape Education Department

- Description: In this study the analysis of the organisational practices in the South African public sector revealed that there is a practical limitation, anchored on the absence of a suitable framework for enhancing the effectiveness of strategic leadership. The research engaged with studies and theories that confirmed that the application of effective strategic leadership enhances the performance of public sector organisations. However, such an analysis revealed no well-defined strategic leadership framework that may be used for improving the successful implementation of programmes in the public sector as a whole and more especially, the Eastern Cape Department of Education (ECDoE). The study therefore interpreted that a significant improvement in the performance of the ECDoE may be effected through the prioritisation of strategic leadership and thereby enhancing its effectiveness. Hence, the primary research objective for this study was to examine strategic leadership and to consider the variables impacting the application of strategic leadership in the ECDoE, so that a framework may be formulated to enhance the effectiveness of strategic leadership in the ECDoE. The data analysis, research observations, findings and interpretations as well as the literature review enabled the researcher to determine the strategic leadership framework that may be postulated for application in the ECDoE. The research data in essence supports the indications in the literature that strategic leadership has a positive effect on enhancing organisational performance and success. The key findings and significant conclusions drawn from the study indicated a definite need to enhance the effectiveness of strategic leadership in the ECDoE and that the associated leadership challenges in the sector have to be addressed to enable more efficient and effective service delivery, increase learner performance and improve organisational success. The researcher has therefore postulated the framework in figure 10 to enhance the effectiveness of strategic leadership in ECDoE and presents it for consideration by the political and administrative leadership for adoption in the ECDoE. The development of this strategic leadership framework by the researcher was informed by the various leadership models, leadership theories, leadership styles and change management strategies examined in the literature review of this study and further directed by the research findings and conclusions that illuminated the challenges that confront ECDoE in the application of strategic leadership in the sector. The framework postulated has three distinct but inter-related steps and this study theorises that the effectiveness of strategic leadership is influenced by the extent to which the managers or leaders determine the specific context and apply the appropriate leadership style (Step 1), implement the selected leadership style in conjunction with the application of appropriate accompanying management strategies (Step 2), and monitor the resulting effects on enhancing the performance of the public sector organisations (Step 3). The researcher also adopted a systems-thinking approach and identified four pillars that transcend organisational service delivery and integrated them to constitute a proposed model for enhancing service delivery, improving implementation of plans and promoting organisational success in ECDoE. The model postulated by the researcher is based on “policies, procedures, systems and structures”, as illustrated in figure 11. The pillars of this proposed model for service delivery are inter-related, inter-locking and at times overlapping. Arising from the literature review and the case study of ECDoE, areas for further research have been identified such as: a more in-depth probing of the significance, role and impact of strategic leadership in all public sector institutions in South Africa; an examination of the Senior Management Services (SMS) mandates given by the Department of Public Service and Administration (DPSA) with regard to strategic leadership; an exploration of the implementation constraints of the National Development Plan (NDP) linked to the positioning of strategic leadership; and, an examination of the role and impact of the training and development programmes in strategic leadership, co-ordinated by the National School of Government (NSG) in South Africa.
