- 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: Voting enables certain formal decisions to be made through the participation of a given population; and it is the vital part of a democratic process. The method of voting used in South Africa (SA) today is derived from the Australian ballot system. This paper-based voting system, however, is slow, convoluted and inaccurate because of human errors; it is costly and largely inefficient. In the early 1900s, election officials overwhelmingly decided to use electronic voting (E-voting) systems to solve some of the problematic issues of paper-based voting systems. Mobile voting (M-voting) is a subset of E-voting; and it allows citizens to use their mobile phones to cast their votes. Very few countries have endeavoured to implement M-voting, in order to improve mobility and simplify the election procedures. Despite several M-voting initiatives reported worldwide; insufficient attention has been devoted to understanding the factors that influence the success or failure of M-voting implementation. It is also important to note that the implementation of M-voting may be very difficult; if the different modalities that aid successful M-voting implementation are not in place. This study seeks to develop a framework that has the potential to enable the successful implementation of M-voting in SA. The proposed framework is an IT artefact that endeavors to improve human experiences for voting. This study followed a Design-Science approach; and it made use of a case study to collect the data via a literature review, observations, questionnaires, focus groups and expert reviews. The study revealed that there is no institutional, legal and regulatory framework for the proliferation of M-voting in SA. Successful M-voting implementation depends on a compendium of factors, which may be unique in the local context where it is implemented. The framework that resulted from the above was assessed for validity and applicability; after which a modified framework was presented. The research concludes with specific implementation guidelines, as well as areas for future research.

- Description: The advances in communication technologies have resulted in a significant shift in the workplace culture. Mobile computing devices are increasingly becoming an integral part of workplace culture. Mobility has several advantages to the organisation, one such example is the “always online” workforce resulting in increased productivity hours. As a result, organisations are increasingly providing mobile computing devices to the workforce to enable remote productivity at the organisations cost. A challenge associated with mobility is that these devices are likely to connect to a variety of networks, some which may insecure, and because of their smaller form factor and perceived value, are vulnerable to loss and theft amongst other information security challenges. Increased mobility has far reaching benefits for remote and rural communities, particularly in the healthcare domain where health workers are able to provide services to previously inaccessible populations. The adverse economic and infrastructure environment means institution provided devices make up the bulk of the mobile computing devices, and taking away the ownership, the usage patterns and the susceptibility of information to adversity are similar. It is for this reason that this study focuses on information security on institution provided devices in a rural healthcare setting. This study falls into the design science paradigm and is guided by the principles of design science proposed by Hevner et al. The research process incorporates literature reviews focusing on health information systems security and identifying theoretical constructs that support the low-resource based secure deployment of health information technologies. Thereafter, the artifact is developed and evaluated through an implementation case study and expert reviews. The outcomes from the feedback are integrated into the framework.

- Description: PUMPS mimics natural geothermal vents as a conceptual model designed for the remediation of acid mine water (AMW) in voids of abandoned gold mines of the Witwatersrand Basin in South Africa. In this system, a reaction chamber containing Desulfotomaculum kuznetsovii sulfate reducing bacteria will be set at the bottom of a 3-4 km deep mine that will be flooded. A geothermal system with at least one (1) doublet will be drilled from the bottom of the mine to the depth of 8km, where the temperatures are sufficient for geothermal energy harvesting. AMW, used as a geothermal fluid, will be pumped down the injection well and circulate through hot rock. The hot water is then used to generate electricity and then channelled into the reaction chamber to undergo bio-remediation. Following treatment, the water flows back into the mine voids where it will improve the quality of untreated AMW through dilution. Eventually, the mine will be flooded with clean water that can be stored underground and/or pumped up to surface for social and ecosystem services. Following an introduction and proof of concept for the PUMPS, the research builds further on the technical and economic evaluation of the PUMPS in order to assert its viability and sustainability. The technical viability includes testing the ability for Desulfotomaculum kuznetsovii to survive in high pressure condition; quantifying the amount of energy that can be drawn from the geothermal reservoir; determining the placement and scheme of the geothermal wells; and, finally, developing a robust economic model of the system. Experiments show that Desulfotomaculum Kuznetsovii can tolerate high pressure conditions in of at least 100bar at their ideal sulfate reducing temperature of 63°C. Geochemical modelling shows that AMW can be used effectively as a geothermal fluid for PUMPS. To achieve highest efficiency and minimal fluid loss, the geothermal wells should be placed along the SSE-NNW direction, based on the known stress field across the Witwatersrand Basin. With a flow rate of 30l/s the energy drawn from the geothermal reservoir is sufficient to drive PUMPS and the surplus energy is determined by the volume of AMW treated per day. All results indicate that the PUMPS is technically and economically viable. The economic model shows that the value and viability of the PUMPS is best reflected with a comprehensive inclusion of potential revenue (for example from chemical solution mining of deep seated gold) and financial/environmental incentives.

- Description: There is consensus that Small to Medium Enterprises (SME) exports play a critical role in the development of economies. It has been widely acknowledged in empirical research done around the world that small businesses make a significant contribution to economic development, employment, competitiveness and the reduction of regional disparities. However, empirical literature gives conflicting evidence on the determinants of export performance among SMEs. The study contributes towards the debate on SME exports by: (i) investigating the variables that determine export performance among SMEs in Zimbabwe (ii) establishing the competi-tiveness of Zimbabwe’s exports and (iii) ascertaining the major constraints faced by SME ex-porters in Zimbabwe The researcher gathered data from 120 SMEs and 10 institutions in Zimbabwe for the period 2009 to 2015. SME samples were chosen from Harare, Mashonaland Central and Mashonaland East provinces while all 10 of the institutions were chosen from Harare province. Convenient non-probability sampling method was used to select SMEs while stratified sampling technique was applied in the selection of institutions. Both qualitative and quantitative research methods were employed. For the quantitative approach, panel data ordinary least squares method was used in the form of the gravity model of trade. Export intensity (used as a measure of exports) was regressed against support institutions, business ownership, research & development, educational years, use of export processing zones, product type, export years, firm size, firm age, gender, distance from trading partner, Gross Domestic Product (GDP) of trading partner, and GDP of Zimbabwe. The random effects estimation method was used, basing on results from the Durbin-Wu-Hausman test. The null hypothesis was based on the premise that the variables under study do not determine export intensity of SMEs in Zimbabwe. Other null hypothesis were that the major constraint faced by SME exporters in Zimbabwe is not access to finance and that Zimbabwe’s exports are not competitive in the mining, agricultural and manufacturing sectors. The revealed comparative advantage index was computed to measure the competitiveness of Zimbabwe’s exports.For the qualitative approach, the study used the triangulation method which involved combining and utilising the questionnaire, interviews and focus group discussions. The results from the study indicated that following variables increased export intensity of Zimbabwean SMEs; business ownership, use of export processing zones, export years, firm size, and GDP of trading partner. The following variables have an inverse relationship with the export intensity of Zimbabwean SMEs: gender, distance from trading partner and research & development. The results also indicated that these further variables do not determine the export intensity of SMEs in Zimbabwe: support institutions, years of education, product type, firm age and GDP of Zimbabwe. The major constraint faced by exporting SMEs in Zimbabwe is limited access to finance. Zimbabwe is competitive in the agricultural and mining sector exports, but not in manufacturing sector exports The policy implication of the findings is that SME support needs to go beyond support institutions when it comes to SME export promotion. Further SMEs in the agriculture and mining sectors need to be promoted for export growth since Zimbabwe is competitive in these sectors. However the manufacturing sector cannot be ignored, since many economies have developed due to exports of manufactured products and a country needs to have balanced export growth in both primary and manufacturing sectors. In order to have motivated, career SME exporters, entrepreneurship education should begin from primary school right up to university so as to improve entrepreneurial aspirations, attitudes and behaviour in the long run.

- Description: Cyanobacterial blooms are becoming more frequent worldwide, with possible negative effects on human health. The effects of climate change and eutrophication have been associated with persistent cyanobacterial blooms becoming more frequent. Altered water characteristics, salinity in particular, influence ecosystem dynamics that may lead to conditions conducive to cyanobacterial blooms. The occurrence of an 18-month long Cyanothece sp. bloom (the longest for any cyanobacterium recorded so far worldwide and the first of the genus) from June 2009 to December 2010 in Africa’s largest estuarine lake, St Lucia, highlighted the susceptibility of ecosystems to anthropogenic alterations. This study investigated the long-term survival and physiological adaptations of Cyanothece sp. to various and dynamic environmental conditions that contributed towards its bloom persistence. The main findings are the high salinities at which Cyanothece sp. could perform important physiological processes such as N uptake, N2 fixation and photosynthesis. Nutrient uptake (both nitrogen and phosphorus) was observed over the full experimental salinity range (0-300) while N2 fixation was only observed up to a salinity of 120. Nutrient uptake rates significantly decreased at this threshold salinity of 120. Interestingly, photosystem II activity was not observed in Cyanothece sp. during this study, but photosystem I activity was robust. Salinity had a minor influence on electron transport rates by photosystem I, high temperature (> 30°C) did however increase electron transport rates. Rapid responses to hypo-osmotic shock (i.e. osmotic downshift during freshening events) by Cyanothece sp. cells also helped minimize cell rupture due to high turgor pressure. Zooplankton abundance within the St Lucia system was negatively correlated with salinity, while grazing experiments indicated that the typical estuarine zooplankton species are able to graze on Cyanothece sp. cells. Therefore, the disappearance of zooplankton at salinities above 60 must have been an important factor in the bloom persistence. Apart from the ecological factors that were at play in St Lucia during the bloom period, the persistence of the Cyanothece sp. bloom can be attributed to the robust nature of their nutrient uptake, nitrogen fixation and photosynthetic systems to maintain activity despite extreme hypersalinity levels.

- Description: Background: South Africa has the highest number of people living with human immunodeficiency virus (HIV) infection in the world. In 2014, an estimated 10.2% of the population was HIV-positive which amounted to 5.51 million people. Efavirenz forms part of the triple therapy backbone used in South Africa and is part of the firstline treatment for HIV. Efavirenz has been strongly associated with causing neuropsychiatric side effects in at least 50.0% of patients to whom it is prescribed. These side effects cause hesitation amongst healthcare professionals to prescribe this agent to patients with active mental illnesses. Aim: The aim of the study was to evaluate the neuropsychiatric side effects of efavirenz in HIV-positive psychiatric and non-psychiatric patients and to determine whether this drug may be recommended for use in an HIV-positive psychiatric patient population. Method: The study was divided into two parts, namely a quantitative portion and a qualitative portion. The quantitative study was a prospective drug utilisation study, while the qualitative portion consisted of semi-structured interviews carried out with healthcare professionals working with people living with HIV/AIDS (PLWHA). The study included five municipal clinics in the Nelson Mandela Metropole as well as two public-sector psychiatric facilities in the Eastern Cape where medical records were reviewed to obtain the information required. Patients were followed in both instances for a period of 24 weeks with follow-up assessments carried out at two, four, 12 and 24 week intervals. In terms of the qualitative study, nurses at the clinics and doctors at the hospitals were contacted and appointments for interviews were made. The interviews were recorded using a voice recorder and were transcribed and analysed using theoretical framework analysis. Results: The review of 126 medical records at the clinics revealed that no patient had suffered from or complained of a neuropsychiatric side effect. This may indicate that patients were not suffering from clinically significant side effects, side effects were not being adequately recorded by healthcare staff, or the healthcare staff were not questioning patients regarding side effects. A total of 26 hospitalised patients were followed for 24 weeks in the psychiatric facilities. Almost half of the patients using efavirenz experienced an improvement in symptoms to the extent that they were iii discharged from the facility. The majority of patients (66.7%) not on an efavirenzcontaining regimen did not improve to the point of discharge.

- Description: Background: South Africa has the highest number of people living with human immunodeficiency virus (HIV) infection in the world. In 2014, an estimated 10.2% of the population was HIV-positive which amounted to 5.51 million people. Efavirenz forms part of the triple therapy backbone used in South Africa and is part of the firstline treatment for HIV. Efavirenz has been strongly associated with causing neuropsychiatric side effects in at least 50.0% of patients to whom it is prescribed. These side effects cause hesitation amongst healthcare professionals to prescribe this agent to patients with active mental illnesses. Aim: The aim of the study was to evaluate the neuropsychiatric side effects of efavirenz in HIV-positive psychiatric and non-psychiatric patients and to determine whether this drug may be recommended for use in an HIV-positive psychiatric patient population. Method: The study was divided into two parts, namely a quantitative portion and a qualitative portion. The quantitative study was a prospective drug utilisation study, while the qualitative portion consisted of semi-structured interviews carried out with healthcare professionals working with people living with HIV/AIDS (PLWHA). The study included five municipal clinics in the Nelson Mandela Metropole as well as two public-sector psychiatric facilities in the Eastern Cape where medical records were reviewed to obtain the information required. Patients were followed in both instances for a period of 24 weeks with follow-up assessments carried out at two, four, 12 and 24 week intervals. In terms of the qualitative study, nurses at the clinics and doctors at the hospitals were contacted and appointments for interviews were made. The interviews were recorded using a voice recorder and were transcribed and analysed using theoretical framework analysis. Results: The review of 126 medical records at the clinics revealed that no patient had suffered from or complained of a neuropsychiatric side effect. This may indicate that patients were not suffering from clinically significant side effects, side effects were not being adequately recorded by healthcare staff, or the healthcare staff were not questioning patients regarding side effects. A total of 26 hospitalised patients were followed for 24 weeks in the psychiatric facilities. Almost half of the patients using efavirenz experienced an improvement in symptoms to the extent that they were iii discharged from the facility. The majority of patients (66.7%) not on an efavirenzcontaining regimen did not improve to the point of discharge. Healthcare staff were vague when providing a definition of neuropsychiatric side effects. There were conflicting ideas on whether or not efavirenz should be used in patients with an active psychiatric illness. Conclusions: Further studies need to be performed in public-sector institutions to obtain a clearer picture of the side effects experienced by patients using efavirenz. Healthcare staff need to be encouraged to keep complete records to allow for meaningful analysis. The further integration of mental health services into existing HIV programmes is essential for holistic treatment. Patients in psychiatric hospitals demonstrated that even patients with psychiatric disorders on efavirenz can experience positive outcomes and stabilisation of psychiatric symptoms, which may indicate that these may not have due to efavirenz use.

- Description: The extended role of today’s pharmacist with the emphasis on patient-focused care has highlighted the need for increased exposure of undergraduate pharmacy students to experiential learning in patient-centred environments, and additional skills development in therapeutics, problem solving and clinical decision making. At the Nelson Mandela Metropolitan University (NMMU), final year pharmacy students complete a university-coordinated, hospital-based, structured experiential learning programme (ELP) for the exit-level module, Pharmacology4. However, the students consistently experience difficulties in the application of pharmacological knowledge during the transition from lecture-based learning to the patient-focused clinical setting. The student population at the NMMU is diverse, with varied cultural, ethnic, language and secondary level education backgrounds, as well as different learning preferences and approaches. The extent to which these factors affect academic achievement in the experiential learning environment is unknown. Central research question The central research question for this study was therefore, “What would be the effect of an intervention aimed at supporting undergraduate pharmacy students during clinical placements, on academic achievement in, and student attitudes towards, experiential learning programmes (ELP)?” In order to explore the research question, several factors which may influence academic achievement in ELPs were investigated, namely: academic achievement (pre-university, in the BPharm programme and, in pharmacology); the admission route into the BPharm programme and the subsequent rate of academic progression; English reading comprehension ability; learning styles; problem solving ability; the extent to which students are prepared for application of knowledge in the ELP, in terms of assessment methods used prior to the final year and previous pharmacy work-based experience. In addition, the students’ lived experience of the ELP was explored, and the need for, and nature of, an intervention was determined. The research was based in a pragmatic paradigm, using an advanced mixed methods approach. An intervention-based, two-phase, quasi-experimental design was employed with an initial exploratory Preliminary Phase (in 2013) preceding the larger experimental framework (Phases One and Two, in 2014 and 2015 respectively). The research design was primarily quantitative, with pre- and post- testing conducted before and after the ELP. The ELP was completed by the comparator cohort in Phase One and the experimental cohort in Phase Two. Supplementary qualitative data was collected before, during and after the ELP. The intervention, in the form of supplementary academic support sessions, was developed from the qualitative data using an iterative approach, and implemented during the ELP in Phase Two. Attitudes and expectations of the students towards the hospital-based ELP were generally positive and realistic. Areas of concern included the difficulties experienced in the application and integration of pharmacological knowledge, both in the clinical setting and the clinical case study-based assessments; students feeling overwhelmed, inadequate and inferior in the clinical environment, compounded by an absence of clinical pharmacists as role models; and feeling unprepared for patient-focused care. The qualitative data strongly supported the need for supplementary academic support sessions. The intervention was developed and implemented in Phase Two, using patient case-based, active learning strategies. The majority of students (91.0%; n = 104) reported improved case analysis skills. A statistically significant (p = .030, Cohen’s d = 0.34) improvement was noted in the summative Pharmacology4 assessment marks obtained by the experimental cohort post-intervention, although of small practical significance. Predictors of academic achievement in the ELP were found to be language, specifically English reading comprehension skills, academic achievement in the BPharm programme and pharmacology, the university admission score, the rate of academic progression, and problem solving ability. Previous pharmacy-based work experience and assessment questions requiring application of knowledge were also found to influence achievement in the ELP. The need for an intervention in the form of supplementary academic support sessions was confirmed. The intervention was subsequently developed and successfully implemented, with student-reported self-perceived improvements in patient case analysis skills. These positive findings were supported by quantitative data which showed a statistically significant improvement in academic achievement in the ELP. Several predictors of academic achievement in the ELP were identified, and invaluable insight was gained into the nature of the difficulties experienced by pharmacy students in the transition from lecture-based learning to experiential learning in patient-focused environments.

- Description: Despite South African citizen’s constitutional right to adequate housing, Government’s housing delivery has been described as a complex, multi-stakeholder, multi-phase problem, exacerbated by political interference and corruption. Housing delivery in South Africa is ideologically and politically designed and executed. However, the government subsidised housing sector remains plagued by: huge and increasing backlogs; corruption; quality concerns, and recipient and stakeholder dissatisfaction. This includes the government subsidised housing construction sector, which faces issues such as: established contractors leaving the sector; late and failed completion; substandard quality; rework; cost overruns; late progress payments; and insolvencies. Moreover, government subsidised housing officials, which forms part of this sector, must contend with abandoned projects and appointing new contractors; shoddy workmanship from sub-standard contractors; remedial work, including demolition and rebuilding; and systemic problems such as staff shortages and under qualified staff. The process of Government’s ideological and political designed and execution may therefore not have considered certain practicalities relative to construction principles and practice. It therefore appears that there may be some relationship between the compatibility of Government’s housing ideological and political designed (policy) and execution and general construction principles and practice. It is clear from the related literature that government subsidised housing construction has mostly been investigated as an exercise observing from the outside in, and not from a construction sector perspective. The main purpose of this study is thus to explore housing policy and practice compatibility as a major obstacle to housing delivery in general and assess whether the current housing policy is sufficiently responsive to the requirements of the government subsidised housing sector by specifically describing and exploring the effects of Government’s housing procurement policies relative to the ability of the construction sector to supply government subsidised housing. More specifically, the study describes and explores corruption, quality; contractors and worker competency, and government capacity as specific consequences of housing policy and practice incompatibility, as well as factors contributing to recipient dissatisfaction and the housing backlog. Finally, based on the finding, a proposed framework for improving the supply of subsidised housing in South Africa has been developed. The methodology for this study adopted a post-positivist philosophy, embracing a quantitative approach using questionnaires, which incorporated mainly five-point Likert type scale, but also multiple-choice questions, as instruments for data collection. Three surveys were conducted, starting with a pilot study and followed by a primary study, during which a total of 2 884 potential participants within the construction sector across South Africa were randomly sampled and solicited to participate, of which 284 responded. The respondents consisted of four groups: general contractors (76); government housing officials (34); built environment professionals (137), and built environment suppliers (37). An electronic questionnaire was sent by email to all potential participants and allowed four weeks to complete the survey. Furthermore, a housing recipient survey was conducted among 100 randomly selected recipients of government subsidised housing in the Nelson Mandela Metropolitan area, by means of a structured interview using a paper based questionnaire, over a period of two weeks. The primary outcome measures used for this study were the ranked mean scores for mainly descriptive analysis and the Chi-square test, the 𝑡-test, Cohan’s d test, ANOVA and Scheffé test, using Cronbach's alpha as a measure of internal consistency of scale and validity, for inferential analyses and hypotheses testing. Hypothesis testing was founded upon Government’s worldview that its policies will not influence the operations of the construction sector relative to housing construction, and therefore tested respondents’ perspectives with respect to the impact that government policies have in terms of contractor operations and contractor success, as well as its contribution towards the housing backlog, substandard housing, recipient dissatisfaction and corruption. The following results were obtained by means of the hypothesis testing:Government housing procurement policies are inappropriate for application in the government subsidised housing sector. Respondents therefore disagree with the notion that government policy and practices do not impact contractor operations and contractor success, and thus the supply of houses; The application of government housing procurement policies leads to inadequate quality. Respondents therefore disagree with the notion that government preferential procurement policies do not impact quality; Government’s housing procurement policies inappropriately target emerging contractors. Respondents therefore disagree with the notion that Government’s targeting of emerging contractors does not impact housing supply; Government has inadequate capacity to address subsidised housing construction sector requirements in terms of housing projects. Respondents therefore disagree with the notion that Government has the capacity to address subsidised housing construction sector requirements in the supply of housing, and Government subsidised houses do not meet recipients’ expectations. Respondents therefore disagree with the notion that government subsidised houses do meet recipients’ expectations. It thus became apparent that housing supply is mostly inhibited by Government’s housing procurement policy, contributing to various factors, such as quality capability, contractor capability, systemic and administrative capacity, and resulting in recipient dissatisfaction. Using Pearson’s product moment correlation, a framework model was developed to illustrate the process flow, which revealed definitive statistical and practical relationships between these factors, and indeed reflects complex relationships between factors inhibiting supply and resulting in recipient dissatisfaction. To find an appropriate framework model for the purpose of improving housing supply, various sources were consulted. Based on the research question, together with the aims and objectives for this study, as well as the realisation that the problems associated with housing supply relate to the project management of the construction phase, which requires interventions for improving supply, it was decided that a results framework would be the most appropriate for this purpose. The proposed framework is therefore a graphical depiction of how the research process may be used to identify problems in the government subsidised housing sector, questioning how these may be resolved, setting strategies to improve the situation, evolving hypotheses and testing these hypotheses to establish the critical factors to be considered in the process of resolving the problem in the housing sector, by means of implementation and feedback.

- Description: Albeit in its infancy, South Africa’s LED practice is a benchmark of a large number of African countries in general and Sub-Saharan African countries in particular. The LED practice stands out, for widespread decentralisation of powers, massive and growing LED budgets, robust legal frameworks that govern its implementation and development of LED structures, amongst others. This study seeks to answer three critical questions: What theoretical LED facets (particular aspects) are available in literature? Are these facets being implemented in Nelson Mandela Bay Municipality (NMBM) and Buffalo City Metropolitan Municipality (BCMM)? Besides the effort and monies invested in ingraining LED in South Africa, are the levels of LED practices of the two municipalities deeply embedded in literature? The study utilises a purpose-built tool to measure the level at which LED practice of respective municipalities is ingrained in LED literature. The thesis employed both qualitative and quantitative research methods in order to provide scientifically adequate answers to this research. The former method was employed in identifying available LED facets while, the latter was useful in measuring the level at which LED practice in the two metros is embedded in LED theory. The research findings reveal presence of 6 LED facets, namely, enterprise development, locality development, livelihoods development, workforce development, community development and LED Governance. However, this study discovered that the aforementioned facets fail to cover other general items like the availability or unavailability of LED strategy, functional location of LED within municipal directorates and availability of a budget to drive the LED functions. In light of this, the researcher decided to group all the other key LED functions that he felt were not finding expression under the 6 facets identified in LED literature. This, then, led to the introduction of “General LED” facets. This facet, besides presenting a pre-cursor to the 6 other facets, manages to capture some key factors that are equally behind the success or failure of LED e.g. the LED strategy factor, a factor which a number of sources name “The heart” or “guiding compass” of successful LED implementation. The “General LED” facet contained other factors like: other plans that aided LED, experience of LED practitioners, budget allocation of the LED function, amongst others. The research found that all the 7 facets are being implemented in both municipalities, albeit to varying degrees. The two metropolitan municipalities’ LED practice, with respect to all the identified LED facets, provided some measure of their respective levels of embeddedness in LED theory using a purpose built tool. The embedded (ness) outcome proved that Nelson Mandela Bay Municipality’s LED practice was embedded in the LED theory across all the 7 facets, namely: general LED, enterprise development, locality development, community development, livelihood development, workforce development, and LED governance. The same analysis proved that Buffalo City Metropolitan Municipality’s LED practice was embedded in LED theory in all the other facets bar community development. The survey results revealed that there are inadequate or limited initiatives in Buffalo.

- Description: Historically psychobiography has focused to a large extent on the study of pathology in human development. In recent years, scholars in the field of psychobiography have recommended that studies with a eugraphic focus be undertaken, thereby investigating optimal human development. Milton Hyland Erickson (1901-1980) was an American psychologist and psychiatrist. An extraordinary creative individual who conducted pioneering work in the field of hypnosis. Whilst vast publications of his academic work exist and his work is continued through the Milton H. Erickson Foundation and its global subsidiaries, in comparison, his life story has not been the focus of much study. The psychobiographical merit of Erickson as the subject of the study was based on his involvement in interesting and important events, as well as his resilient attitude towards life, during even dire moments. The focus of this psychobiography was to conceptualise Erickson’s life in terms of the principles of Adler’s Individual Psychology and Peterson and Seligman’s Character Strengths and Virtues Classification. Through this process it was aimed to provide descriptions and interpretations of Erickson’s personality in order to illuminate aspects such as his creativity, service to others, and optimism. The study is written from the first person perspective and is rooted in the interpretive paradigm. It utilises a qualitative research approach in order to gain an in-depth understanding of Erickson’s finished life and thereby taking into account contextual factors. The two theoretical frameworks guided the iterative data collection and data analysis processes and the data were organised into a descriptive framework. The method of data analysis was idiographic thus describing the uniqueness of Erickson life. Strategies such as the triangulation of data sources and theory, focusing on aspects of saliency, trustworthiness, and ethics were employed to ensure reliable data extraction and interpretation. The study revealed that both theoretical frameworks were appropriate in their description and interpretation of Erickson’s personality and character strengths. Of significance was the protective role that creativity, social interest, hope, and optimism played against trauma and these emerged as central themes in Erickson’s life in terms of his psychological wellbeing. The findings on creativity and social interest are supported by existing research and theory but also highlight perspectives for future research. Creativity is a key component of knowledge production and therefore research in this area could improve our understanding of how it can be nurtured and developed across the lifespan. Whilst the construct of social interest was integral to this study its validity in terms of providing adequate explanations of how individuals balance their own needs against the needs of others was examined and suggestions of where the theory can be elaborated were highlighted.

- Description: Historically psychobiography has focused to a large extent on the study of pathology in human development. In recent years, scholars in the field of psychobiography have recommended that studies with a eugraphic focus be undertaken, thereby investigating optimal human development. Milton Hyland Erickson (1901-1980) was an American psychologist and psychiatrist. An extraordinary creative individual who conducted pioneering work in the field of hypnosis. Whilst vast publications of his academic work exist and his work is continued through the Milton H. Erickson Foundation and its global subsidiaries, in comparison, his life story has not been the focus of much study. The psychobiographical merit of Erickson as the subject of the study was based on his involvement in interesting and important events, as well as his resilient attitude towards life, during even dire moments. The focus of this psychobiography was to conceptualise Erickson’s life in terms of the principles of Adler’s Individual Psychology and Peterson and Seligman’s Character Strengths and Virtues Classification. Through this process it was aimed to provide descriptions and interpretations of Erickson’s personality in order to illuminate aspects such as his creativity, service to others, and optimism. The study is written from the first person perspective and is rooted in the interpretive paradigm. It utilises a qualitative research approach in order to gain an in-depth understanding of Erickson’s finished life and thereby taking into account contextual factors. The two theoretical frameworks guided the iterative data collection and data analysis processes and the data were organised into a descriptive framework. The method of data analysis was idiographic thus describing the uniqueness of Erickson life. Strategies such as the triangulation of data sources and theory, focusing on aspects of saliency, trustworthiness, and ethics were employed to ensure reliable data extraction and interpretation. The study revealed that both theoretical frameworks were appropriate in their description and interpretation of Erickson’s personality and character strengths. Of significance was the protective role that creativity, social interest, hope, and optimism played against trauma and these emerged as central themes in Erickson’s life in terms of his psychological wellbeing. The findings on creativity and social interest are supported by existing research and theory but also highlight perspectives for future research. Creativity is a key component of knowledge production and therefore research in this area could improve our understanding of how it can be nurtured and developed across the lifespan. Whilst the construct of social interest was integral to this study its validity in terms of providing adequate explanations of how individuals balance their own needs against the needs of others was examined and suggestions of where the theory can be elaborated were highlighted.

- Description: South Africa have some of the lowest employee engagement scores in the world. Leadership is a key determinant of employee engagement, but existing leadership theories and practices are often ineffective in more humanistic and collectivistic cultures like South Africa. To this end, Ubuntu and servant leadership is posited to positively influence organisational performance by increasing employee engagement. The primary objective of this study is to investigate perceptions regarding the impact of Ubuntu and servant leadership on employee engagement in private organisations of the Eastern Cape. A quantitative research design was utilised and yielded 428 usable questionnaires through nonprobability sampling. The empirical results revealed that the spirit of solidarity dimension of Ubuntu leadership influenced significantly and positively. Furthermore, it was found that survival and spirit of solidarity had a significant and positive influence on organisational performance as measured through the balanced scorecard (BSC). Servant leadership positively and significantly influenced employee engagement and organisational performance. In addition, it was found that employee engagement mediates the relationship between servant leadership and organizational performance. This study has made several significant empirical and theoretical contributions, and can be classified as one of the pioneering attempts to gather empirical evidence on how Ubuntu manifests in the workplace. The high convergent validity of the dimensions of Ubuntu leadership and comparisons to Servant leadership established in this study, provides some proof of its novel contribution towards leadership theory. A highly reliable and valid measuring instrument was developed to evaluate Ubuntu from a leadership perspective. This is a major empirical contribution as, at the time, there were no reliable scales available in South Africa to measure Ubuntu leadership.

- Description: The resurgence of Islam across the globe combined with the resilience that Islamic financial assets have shown against the onslaught of the current financial crisis, make Islamic finance an attractive alternative financial system. Over the past decade, the Islamic finance sector have shown double digit growth rates beyond the traditional areas of the Gulf Cooperation Council (GCC) regions of Asia as well as other parts of the Middle-East and North Africa (MENA) regions. Research suggests that the future of Islamic finance in Africa depends on business opportunities in South Africa, Kenya, Nigeria and Senegal. The South African government, in conjunction with the national finance authorities, have made their intention clear to position the country as the Islamic finance hub for the rest of the African continent. Despite various marketing campaigns over the past decade to convince the public that Islamic banking and finance is for everyone, non-Muslims generally view Islamic banking as being for Muslims alone. Scepticism towards Islamic finance has resulted in a mere 15 per cent of the estimated 1.5 million South African Muslims currently making use of the sector’s banking and retail instruments. This lack of interest is impacting negatively on the country’s aspirations to establish itself as the gateway of Islamic finance to the rest of Africa. Generally, people’s attitudes toward utilising Islamic finance are regarded as a key obstacle to the development of the Islamic banking and finance system in Muslim minority countries. A Kuwait Finance House research report (2012) highlighted a lack of awareness and knowledge of Islamic finance products and services as key factors stifling the growth of the Islamic finance sector in South Africa. In this context, it was deemed necessary to analyse how knowledge, awareness, expectations, beliefs, perceptions and ancillary external factors impact on potential users’ attitude and decision to adopt or reject Islamic finance.By means of adapting Fishbein’s (2000; 2008) Integrative Model of Behavioural Prediction, a universally-acceptable behavioural-change model, this research explains in a holistic manner how cognitive, affective and environmental measures impact on a Port Elizabethan Muslim’s attitude and eventual decision to accept (or reject) Islamic finance. This study has found that knowledge was the most important variable influencing attitude and intention to use (or reject) Islamic finance. Consequently, this thesis proposed that Islamic institutions should focus their efforts on promoting knowledge and awareness of their products among the South African Muslim and non- Muslim population. As the global Shari’ah finance industry continues its positive growth trajectory, it is imperative that Islamic finance stakeholders in South Africa ensure that they exploit the benefits derived from online learning platforms and assist, by means of cross-border collaborations, more students to have greater access to Islamic finance courses. Furthermore, universities and training institutions are encouraged to offer courses and qualifications in Islamic finance to close the talent gap that currently exist in this particular field of study.

- Description: This research was conducted with the intention of accomplishing effective property management (PM) in order for public sector properties in South Africa (SA) SA to fulfil more remarkably, public sector property stakeholders’ requirements. In particular, this study was concluded within a South African municipal environment with the specific purpose of alleviating South African municipalities from problems associated with overall poor operational performance, dissatisfied public sector property stakeholders, and inadequacies in competitiveness and global alignment. The primary objective of this study was to develop a performance model deemed necessary for the effective management of public sector properties in SA. This was achieved by developing a performance model for effective management of public sector properties, a model to systematically monitor, measure and control current expectations and changes within a public sector property management function. Herewith, performance model for effective management of public sector properties in South Africa. At the time of conducting this study, there was no conceptual model developed for performance management of public sector properties. In order to develop the performance model, the conceptual model identified key elements that included: 1) obsolescence and strategic factors; 2) global alignment; 3) finance and cost control; 4) PESTEL impact; 5) transformation and sustainability; 6) leadership and governance; and 7) monitoring, measurement and control as influences that directly impact a perceived successful management of public sector properties in SA. The study also took the form of a quantitative research project that included a formal survey of the identified population sample. The main statistical procedure employed was Structural Equation Modelling (SEM). Originally, the study offered 24 hypotheses; however, only 11 hypotheses could be confirmed by SEM measurement. Therefore, through SEM, the significance of the relationships between variables could be tested. Appropriate quantitative data were collected from public and private South African Built Environment professionals, students and other academics. The research made use of snowball sampling through questionnaires, with a sample size of 171. It is anticipated that findings of this study will be acknowledged by public sector PM in an effort to resolve PM problems through the incorporation of pertinent recommendations. Likewise, since the performance model for effective management of public sector properties was not extant prior to this study, this research is cutting-edge and therefore pioneering to PM, especially within the public sector.

- Description: This study is divided in to two main parts. The first part deals with the optimization of process parameters of needle-punched non-woven fabrics for achieving maximum sound absorption by employing a Box-Behnken factorial design. The influence of fibre type, depth of needle penetration and stroke frequency on sound absorption properties were studied. These parameters were varied at three levels during experimental trials. From multiple regression analysis, it was observed that the depth of needle penetration alone was the most dominant factor among the selected parameters, which was followed by the interaction between depth of needle penetration and stroke frequency. Fibre type was the least dominant parameter affecting sound absorption. A maximum sound absorption coefficient of 47% (0.47) was obtained from the selected parameters. The results showed that for a process such as needle-punching, which is influenced by multiple variables, it is important to also study the interactive effects of process parameters for achieving optimum sound absorption. The second part of the study deals with the effect of type of natural fibre (fineness), and the blending ratio (with PET fibres) on the air permeability of the needle-punched non-woven fabrics and then it proceeds to study the effect of the air-gap, type of natural fibre (fineness) and blending ratio (with PET fibres) on sound absorption of needle-punched non-woven fabrics. These parameters are tested individually and their two way interaction (synergy) effect using ANOVA. The air-gap was varied from 0mm to 25mm with 5mm increments, three natural fibre types were used and all were blended with polyester fibres at three blending ratios for each natural fibre type. The Univariate Tests of Significance shows that all three parameters have a significant effect on sound absorption together with two two-way interactions, with the exception of the Blend Ratio × Air Gap two-way interaction which was not significant. It was found that the sound absorption improves with the increase in the air-gap size up to 15mm after which sound absorption decreased slightly with the further increase in the air-gap up to 25mm.

- Description: This study examined the impact of trade liberalisation on Kenya. It analysed the influence of trade liberalisation on trade creation, trade diversion, exports, imports, revenue effects and welfare effects. The developments in trade liberalisation and free-trade economic arrangements were introduced in Kenya and many developing countries in the early 1980s and strengthened from 1990s onward. The short term effects of the structural-adjustment programs were characterised by poor balance of payment conditions, high levels of unemployment, contraction of the imports from other countries, and government revenue losses, among other social problems. Notwithstanding the dismal performance of the Kenyan Economy after liberalisation, the Kenyan government continued to liberalise its trade under various frameworks such as the Economic Partnership agreements (EPAs) with the European Union, the World Trade Organization (WTO) and various bilateral free-trade agreements (BFTA) with its largest trading partners. This study used the World Integrated Trade Solutions-Software for Market Analysis and Restrictions on Trade (WITS/SMART) using 2008 as the base year. This method was used mainly because of its strengths to analyse the tariff effects of a sole market on disaggregate product lines. In addition the WITS/SMART model is able to analyse the impact of trade liberalisation in scenarios of imperfect substitutes. Hence, this study used the WITS/SMART Model to examine the trade liberalisation framework for Kenya under comprehensive implementation of COMESA customs Union, COMESA FTA, WTOFTA and the EPAs. The comparative valuation of the trade-creation effects reveals that the WTOFTA expected the highest trade-creation effects of US$995.16 million. This was followed by the various bilateral free-trade agreements which had a trade-creation effect of US$333.04 million, then COMESACU which had a trade-creation effect of US$310.50 million followed by the EPAs with a value of US$129.45 million. COMESA FTA was expecting trade-creation effects valued at US$15.51 million. These trade-creation effects are expected to cause unemployment through de-industrialisation. This study has also noted that WTO FTA and COMESA CU had no evidence of trade diversion. However, BFTA, EPAs and COMESA FTA showed evidence of trade diversion of US$134.88 million, US$89.28 million and US$2.61 million respectively. This study also examined the possible revenue effect from the free-trade agreements and customs union. It was noted that most losses emanated from the WTOFTA, which was valued at US$817.15 million. This was followed by the COMESACU protocol, which is expected to register a loss amounting to US$327 million. The third free-trade agreement with the highest losses comprised the various BFTAs amounting to US$304 million. The forth probable losses were anticipated from EPAs amounting to US$142 million. The free-trade agreement with the least losses is COMESA FTA with an expected loss of US$7.88 million. The consumer welfare effect was done to assess if consumers benefitted from trade agreements. This study observed that the WTOFTA expected the highest consumer welfare effect of US$103.98 million. This was followed by the various COMESACU with an expected consumer welfare effect of US$56.27 million. The BFTA were the third with a consumer welfare effect of US$ 41.82 million. This was followed by the EPAs with a consumer welfare value of US$ 17.56 million. The trade protocol with the least-expected consumer-welfare effect was the COMESA FTA valued at US$ 1.60 million. Although welfare gains resulting from the anticipated trade agreements were an indication of potential benefits to Kenyans, they were insignificant. This study also analysed the export performance from five different trade agreements and their impact on Kenya. The BFTA expected an export value US$4.63 billion, followed by the EPAs with an expected export value of US$2.18 billion. The third largest export values was WTOFTA with an export value of US$12.12 billion, the fourth being COMESAFTA having an export value of US$ 434.28 million and finally COMESACU with an expected export value of US$394.14 million. The study showed that major exports were composed of minerals, tobacco and agricultural products dominating the export basket. The export destinations were expected to be the WTO members, which include Uganda, Congo, Egypt, Rwanda, Sudan and Zambia. Kenya expected an increase in imports mainly from the WTO amounting to 8.95 per cent. This was followed by the BFTA rated with an expected 3.2 per cent growth in imports. The third protocol expecting import growth was the COMESACU of 2.8 per cent import growth and the EPA with 1.16 per cent import growth, and finally, 0.07 per cent import growth from the COMESA FTA. The expected increase in imports is anticipated to create balance of payment problems for Kenya. The results of the study show that the welfare gains from trade liberalisation were not able to compensate for the revenue losses. The study also showed that Kenya was not able to make optimal use of trade liberalisation to expand its export destinations; as the COMESACU was expected to reduce exports. In light of these findings, the study recommends that measures aimed at boosting exports like strengthening of the Export Processing Zones, export subsidies, the establishing of supply-side facilities, trade financing plus strengthening of the export-supporting institutions. It is important to note that the findings of this study provide an opportunity for Kenya, and other developing countries, to implement measures to ensure that they achieve optimal benefits from the various regional trade agreements.

- Description: How a country is perceived by foreign investors is becoming increasingly significant to the ability of individual countries to attract foreign direct investment into their economies. In Africa, existing negative perceptions of the continent as an investment destination have been considered as an obstacle for foreign direct investment inflows to the continent in general. Although Zimbabwe offers foreign investors multiple lucrative investment opportunities, attracting foreign direct investment to the country presents a unique challenge due to the image of the country post the 1998-2008 economic crisis. Despite the vast research on the determinants of foreign direct inflows to particular countries, little is known about whether non-financial image-related factors influence the inflow of foreign direct investment to a particular country, especially a country with a unfavourable global image like Zimbabwe. The primary objective of this study was therefore to determine the perceived non-financial nation brand image factors considered to be influential for attracting specific foreign direct investment inflow opportunities in Zimbabwe. A comprehensive literature review resulted in the identification of nine independent variables (tourism, governance, people, culture and heritage, exports, investment and immigration, factor endowments, infrastructure, and legal and regulation frameworks), as well as four dependent variables (market-, resource-, efficiency- and strategic asset-seeking foreign direct investment inflow opportunities in Zimbabwe). A hypothesised model was developed in order to examine whether the independent variables have an influence on the dependent variables, and as a result nine hypotheses were formulated to test the relationships between the nine independent variables and each of the four dependent variables. A cross-sectional, quantitative deductive approach to research was employed in order to generate the data required for hypothesis testing. Purposive sampling techniques were employed to draw the sample frame for the study. A self-administered online survey was conducted, and generated empirical data from a final sample comprised of 305 investors who had applied to invest in Zimbabwe through the Zimbabwe Investment Authority between January 2009 and April 2015. Data was analysed using STATISTICA 12 software. Exploratory factor analysis was utilised to extract the constructs and validate the measuring instrument. Cronbach’s alpha coefficients were calculated in order to test the reliability and internal consistency of the measuring instrument. As a result, a total of six valid and reliable independent variables, and four dependent variables were retained for further analysis. The results of the Pearson product-moment correlation coefficients revealed mostly moderate correlations. The Multi-Collinearity diagnostics test confirmed the absence of collinearity between the independent variables and dependent variables respectively. Subsequently, the results of the four sets of multiple regression analyses, disclosed thirteen statistically significant relationships between the six independent variables and the four categorical dependent variables. Tourism had significant relationships with market-, efficiency- and strategic asset-seeking FDI inflow opportunities. Government actions had significant relationships with resource- and strategic asset-seeking FDI inflow opportunities. People had significant relationships with resource- and efficiency- seeking FDI inflow opportunities. Export had significant relationships with market-, resource-, efficiency- and strategic asset-seeking FDI inflow opportunities. Regulatory framework had significant relationships with market- and resource-seeking FDI inflow opportunities. The results of the Analysis of Variance revealed that investor status can be used to predict which non-financial nation brand image determinants played a role in the ultimate decision for taking up foreign direct investment opportunities in Zimbabwe. Further analysis of the role that the demographic profiles of the investors played in predicting which non-financial nation brand image determinants are considered influential in taking up foreign direct investment opportunities in Zimbabwe was confirmed in the Multivariate Analysis of Variance with thirty-four statically significant relationships identified. Further analysis by means of post-hoc Scheffé testing and Cohen’s d-values calculations confirm that thirty-nine practically significant mean differences were evident. This study makes a novel contribution to the empirical body of nation branding, foreign direct investment and investment promotion research by developing and testing a hypothetical model that synthesises facets of the three fields of study. This study represents a new discourse in the identification of the determinants of FDI (that being non-financial determinants) and provides an explanatory framework for the non-financial nation brand image determinants influencing each type of FDI inflow opportunity sought in Zimbabwe. It is within this framework that recommendations, based on empirical evidence, are made for the Government of Zimbabwe and the Zimbabwe Investment Authority. Some of these recommendations could be implemented within the short-term, while others may be more strategic in the long term. Recommendations made include that the Government of Zimbabwe undertakes significant policy reviews, continues its engagement with key external stakeholders such as other governments, supra-national financial institutions, and foreign investors, as well as adhering to existing favourable FDI policies. It is also recommended that the Zimbabwe Investment Authority adopt an intermediary role, by linking the Government of Zimbabwe with potential foreign investors through investor targeting, as well as promoting Zimbabwe as an investment destination by engaging in image-building activities such as public diplomacy, investor relations, specialised advertising and hosting investor forums with multiple, distinct investor segments. These image-building activities should be centered on the non-financial nation brand image determinants that foreign investors consider to be influential to foreign direct investment in Zimbabwe, and should be geared towards improving and managing the perceived image of Zimbabwe as an investment destination.

- Description: The aim of this study was to describe occurrences of peer harassment and the influences it has on Form Three learners in Zimbabwean rural day secondary schools. A review of studies conducted internationally indicated that peer harassment is prevalent and is stressful for most learners. Reports indicate that the negative impacts of peer harassment limit the educational achievements of the learners, and that learners need teacher and parental assistance to deal with peer harassment. In particular there appears to be a need for the creation of safe learning environments. This study was informed by an eclectic framework based on Erik Erikson's psychosocial theory, Bronfenbrenner's socio-ecological theory and Allardt's social welfare theory. These three theories point to the need for understanding that the social supports available to an individual determine how the individual perceives and responds to all his or her experiences. Investigations of the perceptions which individuals hold of their diverse lived experiences are best understood from a qualitative paradigm. Since the study intended to gain an understanding of the forms of peer harassment experienced by learners and how their individual experiences influenced their wellbeing, a phenomenological design was used. The sample was comprised of fifteen Form Three (grade 10) learners from three rural schools who volunteered to share their experiences of peer harassment. Data generated from semi-structured interviews with the individual participants were analyzed revealing emergent themes to answer the research questions. Findings revealed that the learners experienced various forms of peer harassment with physical peer harassment being the most prevalent. The data also revealed that peer harassment had both psychological and social influences on the well being of the learners which were primarily negative. Most learners felt that they were not getting adequate support from the adults (i.e., their teachers and the parents and guardians. The apparent reason for this lack of support from the adults was related to the community values which adults held about how learners were expected to deal with peer harassment. It was also evident that most learners chose to suffer silently, or hoped that God would intervene to assist them. Teachers were also not doing enough to assist the learners to stop peer harassment. Like the parents and guardians, most of the teachers did not perceive peer harassment as a serious problem in learners' lives so they did very little to assist victims who complained to them. Learners relied primarily on friends for support. The study concluded that peer harassment influenced the learners 'psychological and social well being negatively. It provided recommendations for schools, teachers, parents and the learners themselves. These stakeholders may collaborate to establish anti-harassment policies and to inform the design and implementation of anti-harassment policies in Zimbabwean rural schools. Recommendations are also provided for further studies aimed at identifying effective responses to the phenomenon of peer harassment.

- Description: Psychobiography can be viewed as the re-writing of an individual‟s life story previously undetected. In general, it consists of a combination of two central elements: biography and psychological theory, which aim to explain the particular individual‟s psychological development. This particular study serves to explore the extraordinary life of renowned singer and songwriter, Ian Kevin Curtis (1956-1980), who died by suicide at the early age of 23. The basis for this investigation will take the form of notable biographical accounts of the subject‟s life, together with the application of Thomas Joiner‟s (2005) interpersonal-psychological theory of suicide which identifies factors that lead to suicidal ideation - in an attempt to understand the psychological circumstances that contributed to Curtis‟s suicide. In doing so, Adler‟s (1929) theory of Individual Psychology was applied to the life of Curtis in an attempt to build on Joiner‟s theory. This led to the concept of control being introduced and contributed to the development of an intake form to identify those at risk for suicide. It is hoped that exploring the psychological circumstances that contributed to Curtis‟s suicide and their interpretation by the subject will bring about an understanding of the risk factors that may induce suicide and, by extension, will highlight the relevance of this psychobiographical study as a tool for investigating and promoting preventative measures concerning suicide. The psychobiographical data collection and analysis for this research thesis will be guided by Yin‟s (2003) theory of „analytic generalisation‟ which uses a theoretical framework in selecting relevant data which develops a matrix as a descriptive framework for organising and integrating that data, and Alexander‟s (1988) analytical model which focuses on lifting out themes through principal identifiers of salience.

Video games as “play assemblages”: applying philosophical concepts from deleuze and guattari to create a novel approach to video games

- Description: The phenomena that we collectively refer to as “play” form a significant part of life at numerous levels. According to the play scholar, Johan Huizinga, play has not only been part of all human societies, it is also at the root of the development of numerous cultural activities, including structured games and sports, certain judicial and legal activities, war, and numerous forms of art. Despite its importance, play, with its various manifestations, is often relegated to being a children’s activity or an occasion of pure waste, and is a surprisingly marginalized topic in academic scholarship. In part to remedy this deficit, my aim in this thesis is to explore the comparatively new phenomenon of video games as a particular form of play. While there are undoubtedly many philosophical approaches that can respond to different aspects of the “problem” of video games, I propose that Gilles Deleuze and Felix Guattari’s philosophy of “difference” and “becoming” is particularly useful. On the one hand, Deleuze and Guattari’s philosophy provides a viable framework through which to determine the limitations of the current prominent theories in the field of video game studies, which include “narratology”, “ludology”, and the more recent “hybrid approach”. On the other hand, their philosophy enables one to extend the creative and transformative potential that is inherent to a philosophical “problem”, in this case the “problem” of video games. By adapting selected Deleuzian and Deleuzoguattarian philosophical concepts, including “assemblage”, “percept”, “affect”, “transversal becoming”, and “becoming-imperceptible”, I aim to establish a philosophical framework through which different forms of play, and different video games, can be analyzed in terms of their capacity to generate “difference” and “becoming”. More specifically, I argue that video games can be understood as particular kinds of “play assemblages” that can potentially open the player to “transversal becomings”. The video games that I analyze as play assemblages that can generate “transversal becomings” are Thatgamecompany’s Flower (2009) and Journey (2012). Importantly, “transversal becomings”, understood in this instance as the “becoming-other” of human individuals, have the potential to contribute to the individual’s capacity for creative thought and action. Therefore, I argue that video games, far from being activities of pure waste, can potentially open the player to various forms of “becoming-other”, which can, in turn, increase the player’s capacity to think differently, to become different and to create differences. Ultimately, I aim to promote the value of play and video games on the one hand, and the value of Deleuze and Guattari’s philosophy on the other hand, for the aim of extending the questioning power of life, and increasing our capacity to effectively respond to a continuously changing world of problems.
