- Description: In South Africa, the quality of health care is directly related to the concept of patient-centred care and the enactment of the Batho Pele Principles and the Patients’ Rights Charter. The quality of health care delivery has dropped drastically, and reports in the media indicate that public hospitals in the Eastern Cape Province are on the brink of collapse, with thousands of patients being treated in condemned hospitals. Receiving and rendering health care in the face of such challenges, the question arose: “Are patients receiving patient-centred care in public hospitals?” The answer to this rhetorical inquiry appeared to be obvious, but this research study explored and described professional nurses’ perceptions of patient-centred care in public hospitals and their understanding of evidence-based practice and best practice guidelines. The proposed study followed a qualitative, exploratory, descriptive and contextual design. The research population included professional nurses who are employed in public hospitals in Nelson Mandela Bay, and consisted of nurse managers and nurses who work in the wards. The research study consisted of three phases. In Phase 1, semi-structured interviews and focus groups were conducted with nurse managers and professional nurses working in the wards in order to collect data about their perceptions of patient-centred care and their understanding of evidence-based practice and best practice guidelines. The interviews were transcribed and Tesch’s eight steps of data analysis were followed to create meaning from the data collected. Themes were identified and grouped together to form new categories. The researcher ensured the validity of the study by conforming to Lincoln and Guba’s model of trustworthiness, which consists of the following four constructs: credibility, transferability, dependability and confirmability. An independent coder assisted with the coding process. In Phase 2, an integrative literature review was conducted in order to identify previous guidelines regarding best practice for patient-centred care. Relevant guidelines were selected, critically appraised, data was extracted and synthesised for the development of a best practice guideline for patient-centred care. An independent appraiser critically appraised the guidelines, thereby ensuring trustworthiness. In Phase 3, the data in Phase 1 and Phase 2 were integrated to formulate a draft best practice guideline for patient-centred care. The guideline was submitted to an expert panel for review and was modified according to the recommendations of the panel, whereby the best practice guideline for patient-centred care in public hospitals in Nelson Mandela Bay was finalized.

A method for the evaluation of similarity measures on graphs and network-structured data

- Language: English
- Type: Thesis , Doctoral , DPhil

- Description: Measures of similarity play a subtle but important role in a large number of disciplines. For example, a researcher in bioinformatics may devise a new computed measure of similarity between biological structures, and use its scores to infer bio-logical association. Other academics may use related approaches in structured text search, or for object recognition in computer vision. These are diverse and practical applications of similarity. A critical question is this: to what extent can a given similarity measure be trusted? This is a difficult problem, at the heart of which lies the broader issue: what exactly constitutes good similarity judgement? This research presents the view that similarity measures have properties of judgement that are intrinsic to their formulation, and that such properties are measurable. The problem of comparing similarity measures is one of identifying ground-truths for similarity. The approach taken in this work is to examine the relative ordering of graph pairs, when compared with respect to a common reference graph. Ground- truth outcomes are obtained from a novel theory: the theory of irreducible change in graphs. This theory supports stronger claims than those made for edit distances. Whereas edit distances are sensitive to a configuration of costs, irreducible change under the new theory is independent of such parameters. Ground-truth data is obtained by isolating test cases for which a common outcome is assured for all possible least measures of change that can be formulated within a chosen change descriptor space. By isolating these specific cases, and excluding others, the research introduces a framework for evaluating similarity measures on mathematically defensible grounds. The evaluation method is demonstrated in a series of case studies which evaluate the similarity performance of known graph similarity measures. The findings of these experiments provide the first general characterisation of common similarity measures over a wide range of graph properties. The similarity computed from the maximum common induced subgraph (Dice-MCIS) is shown to provide good general similarity judgement. However, it is shown that Blondel's similarity measure can exceed the judgement sensitivity of Dice-MCIS, provided the graphs have both sufficient attribute label diversity, and edge density. The final contribution is the introduction of a new similarity measure for graphs, which is shown to have statistically greater judgement sensitivity than all other measures examined. All of these findings are made possible through the theory of irreducible change in graphs. The research provides the first mathematical basis for reasoning about the quality of similarity judgments. This enables researchers to analyse similarity measures directly, making similarity measures first class objects of scientific inquiry.

- Description: The perceptions of employees regarding electronic surveillance in the workplace were studied using a mixed method approach. The change that permeates society and organisations have not escaped public FET institutions in South Africa. These changes such as computerisation of work and the employment of electronic surveillance, have implications for management, control, privacy, productivity and trust in the workplace. Yet, public FET institutions are not performing to the expected standards. Surveillance of work and employees at these institutions are interventions of management to ensure organisational goals are achieved. Despite the prevalence of electronic surveillance in the workplace, employee perceptions and their lived experiences thereof are seldom reported. Published research barely focuses on employees’ perceptions of electronic surveillance in the workplace, and instead offers a perfunctory look at the perceptual dimensions. Employees’ perceptions reflects their lived experiences in the workplace and yield a foundational understanding of workplace dynamics and organisational behaviour. The perceptions of employees regarding electronic surveillance were viewed through the lens of quantitative and qualitative analysis to give statistical and thick descriptions respectively to augment better understanding. The study therefore provides a descriptive account of employees’ perceptions of electronic surveillance and its effects. Specifically the study examined employee perceptions of electronic surveillance as a control measure of management, as an intrusion of employee privacy and impacting on the trust relationship and productivity. An extensive review of the literature provided the basis for the research questions and eight hypotheses were proposed. A survey, by means of an electronic questionnaire, was conducted to test the hypotheses using a random sample of employees at three public FET institutions in the Eastern Cape Province, South Africa. The results are presented followed by a discussion, conclusions and limitations. Suggestions and recommendations for future research are also indicated. The central thesis of the study is presented, namely that electronic surveillance is experienced as a measure of management to control workers and that privacy as well trust, as an element of the employment relationship, are influenced by it. Further findings indicated that there are no statistically significant differences in the responses of the three job categories namely lecturers, managers and administration and support staff. Interviews were also conducted and the data from the interviews reported the depth and breadth of the perceptions of a small sample of employees who related their experiences and situations in terms of the key themes of electronic surveillance as control and an intrusion of their right to privacy, trust and productivity. The findings indicate that acceptance of electronic surveillance is contingent upon contextual factors and the meaning people assign to their situations. Privacy concerns were limited to personal information, fairness and dignity. The link between electronic surveillance and control and discipline is reported in the responses. The findings indicate that perceptions of electronic surveillance as managerial control is related to the lived experiences of employees. Employees voiced positive perceptions of electronic surveillance in cases where management clearly communicates the purpose to the employees. The study of the subjective experiences of employees in workplaces under electronic surveillance thus helped to illuminate the intricacies of employment relationships in the changing world of work. The study findings widen the knowledge base on organisational behaviour and is essential for human resources management and organisational development interventions. Human rights and ethics are part of the sense making process when employees construct social reality. Management and control is redefined in various terms and has implications for change management strategies and organisational development practises in globalising and network society. The study raises the critical question whether electronic surveillance as an adjunct for bureaucratic control is still relevant in a changing world of work where good faith, trust and confidence are still highly valued. The insights into the role of trust in the employment relationship is important for managing public institutions in complex settings. Management must be aware of the differences in the lived experiences of employees when dealing with workplace issues.

- Description: Organizations face challenges constantly owing to limited resources. As such, to take advantage of new opportunities and to mitigate possible risks they look for new ways to collaborate, by sharing knowledge and competencies. Coordination among partners is critical in order to achieve success. The segmented South African public sector is no different. Driven by the desire to ensure proper service delivery in this sector, various government bodies and service providers play different roles towards the attainment of common goals. This is easier said than done, given the complexity of the distributed nature of the environment. Heterogeneity, autonomy, and the increasing need to collaborate provoke the need to develop an integrative and dynamic coordination support service system in the SA public sector. Thus, the research looks to theories/concepts and existing coordination practices to ground the process of development. To inform the design of the proposed artefact the research employs an interdisciplinary approach championed by coordination theory to review coordination-related theories and concepts. The effort accounts for coordination constructs that characterize and transform the problem and solution spaces. Thus, requirements are explicit towards identifying coordination breakdowns and their resolution. Furthermore, how coordination in a distributed environment is supported in practice is considered from a socio-technical perspective in an effort to account holistically for coordination support. Examining existing solutions identified shortcomings that, if addressed, can help to improve the solutions for coordination, which are often rigidly and narrowly defined. The research argues that introducing a mediating technological artefact conceived from a virtual community and service lenses can serve as a solution to the problem. By adopting a design-science research paradigm, the research develops a model as a primary artefact to support coordination from a collaboration standpoint. The suggestions from theory and practice and the unique case requirement identified through a novel case analysis framework form the basis of the model design. The proposed model support operation calls for an architecture which employs a design pattern that divides a complex whole into smaller, simpler parts, with the aim of reducing the system complexity. Four fundamental functions of the supporting architecture are introduced and discussed as they would support the operation and activities of the proposed collaboration lifecycle model geared towards streamlining coordination in a distributed environment. As part of the model development knowledge contributions are made in several ways. Firstly, an analytical instrument is presented that can be used by an enterprise architect or business analyst to study the coordination status quo of a collaborative activity in a distributed environment. Secondly, a lifecycle model is presented as meta-process model with activities that are geared towards streamlining the coordination of dynamic collaborative activities or projects. Thirdly, an architecture that will enable the technical virtual community-centric, context-aware environment that hosts the process-based operations is offered. Finally, the validation tool that represents the applied contribution to the research that promises possible adaptation for similar circumstances is presented. The artefacts contribute towards a design theory in IS research for the development and improvement of coordination support services in a distributed environment such as the South African public sector.

- Description: The issue of ethics on the internet has become complicated due to a number of people placing material on cyberspace. NGOs are increasingly using social media to promote their products and services. Jürgen Habermas’ theory of communicative action and discourse ethics as a theoretical basis to the study merges together several factors which impact on the use of social media as a communicational tool for social marketing. The study explores how eight “ethical variables” (ethical and moral problems) are impacted by social media. The variables- justice, privacy, access, accuracy, truth, human dignity, regulation and ownership of information are a basis of enquiry by conducting in-depth interviews with employers/managers of 10 selected South African NGOs, as well as distributing survey questionnaires to 150 employees/volunteers of the NGOs to determine their experiences with cyberspace. The research investigates the social contexts of the selected NGOs and the safety measures they implement to protect their reputations and corporate identities. The study analyzes unethical behaviours that exist within the selected virtual organizations of the NGOs and investigates the ethical guidelines they follow in order to deal with the breaches of ethics. The study offers recommendations into amending drafted or existing public procedural policies for the purpose of self-regulating present and future users of social media. The study proposes that the continued misuse of social media may cause social media guidelines to be embedded into existing national legislative frameworks, such as South Africa’s Bill of Rights, as well as media and communications Acts.

- Description: The construction industry produces a high rate of accident statistics. Constructors are exposed to a range of construction hazards and risks which manifest themselves in accidents and lead to a high incidence of illnesses, injuries and fatalities. Despite evidence that up to 50 percent of construction accidents can be avoided through mitigation of hazards and risks in the design phase of construction projects, architectural designers do not adequately engage in designing for construction health, safety, and ergonomics. The research localises the problem in the context of South Africa and sets out to develop an architectural design oriented model toward a reduction of construction hazards and risks, which can be engendered through optimisation of tertiary architectural education and through continuing professional development (CPD) programmes. The ultimate aim is to realise a paradigm shift in architectural design relative to construction health, safety, and ergonomics as architectural designers in South Africa still view it as the constructor’s responsibility. The research intertwined a range of secondary data with four provisional studies undertaken in the Eastern Cape Province considered representative of South Africa. This involved both quantitative and qualitative methodologies and were directed at architectural designers registered with the South African Council for the Architectural Profession (SACAP). The provisional studies were published in international conference proceedings and served to gradually provide local insight, and ultimately provided a line of structured questions for use in the main study. The main study was positioned in the action research (AR) paradigm and used focus group (FG) methodology to solicit a vast richness of qualitative data from SACAP registered architectural designers who participated in the FG proceedings. Synthesis of data with literature and the provisional studies gave rise to a provisional model comprising six main model components and a range of sub-components. The provisional model was validated and refined while simultaneously testing the research hypotheses by means of questionnaires directed at the SACAP registered FG participants. The evolved model includes a core model embedded in a greater process model, and implementation and use of the core model relies on appropriate knowledge of architectural designers. It is ultimately recommended that tertiary architectural education institutions and those involved in architectural CPD programmes take ‘upstream design ownership’ and use the model as a basis for designing and implementing appropriate tertiary architectural programmes and architectural CPD offerings. Ultimately the model is not considered as a complete means to an end, and further investigation is needed in order to design and implement the recommended programmes. Only then can we begin to realise a paradigm shift in architectural thinking and practice.

Nonetheless, the industry is reportedly bedevilled by a high rate of accidents and serious injuries that often lead to permanent deformation and fatalities among workers and the general public. These accidents and injuries manifest due to poor construction health and safety (H&S) performance that is often related to poor H&S leadership of the key project leaders involved in the construction business. Shortcomings pertain to client leadership in terms of involvement and commitment to H&S and project H&S related decisions of professionals (designers, project managers, quantity surveyors and engineers). They also pertain to contractor related aspects such as H&S management systems and leadership at all levels of management. In addition, contractors’ inadequacies of H&S management relative to workplace planning and materials related issues have continued to marginalise H&S performance in construction. The H&S leadership of key project leaders is very important in creating a culture of H&S in the workplace. This study examined the H&S management practices and leadership of the key project leaders that contribute to at-risk work practices or unsafe behaviour of workers. Presently, there is limited or no research in South African construction on how the H&S leadership of the key project leaders contributes to at-risk work practices or unsafe behaviour of workers. The methodology employed in the study included an extensive review of relevant literature, which enabled the field work to proceed unhindered. The quantitative survey and qualitative inquiry was conducted with the key construction participants in South African construction. Focus group discussions and interviews were used in a complementary manner. Accordingly, the sampling technique for the study comprised simple random and purposive sampling. The study revealed apparent poor leadership and lack of involvement and commitment to workers’ H&S by the key project leaders. Notably, there is statistical evidence of poor H&S management practices among contractors in terms of top management commitment to and involvement in project H&S. This statistical evidence includes poor H&S education and training of workers and lack of workers’ involvement and participation in H&S matters, which is the tenet of behaviour-based H&S anagement. The model of leadership influence on worker H&S behaviour developed in this research constitutes an innovative contribution to construction H&S performance improvement through a leadership-focused approach. The study has established a basic level of awareness and understanding among key project leaders in that their upstream decisions during the project planning and construction phases have significant influence on workers’ safe or unsafe behaviour or at-risk work practices. The study strongly advocates transparent leadership, ethical behaviour among clients in public and private sectors, designers’ critical H&S decisions, project managers’ and quantity surveyors’ commitment towards project H&S and contractors’ adoption and implementation of behaviour-based H&S management systems. The developed leadership influence model of worker H&S behaviour in the study provides a useful guide for the key project leaders to realise the desired H&S performance improvement in the South African construction industry.

- Description: This research examines the relationship between business, the state and society in South Africa -- particularly the Western Cape -- over the period from 1960 to 1990, viewed against the background of economic conditions in this region, South Africa and the world. Utilising a development history approach, it is based on an extensive study of primary and secondary documentation, supplemented by a panel of in-depth interviews and observation. This study finds that the relationship between business and apartheid incorporated both functional and dysfunctional elements, although over time the benefits diminished and the costs multiplied. The latter, Regulation Theory suggests, is true for any institutional order, but it could be argued that, under apartheid, the particularly fragile and contradictory nature of the institutional arrangement made inevitable crises more rapid and more pronounced. On the one hand, apartheid restricted the economic development of the country, as a result of a range of factors from skills shortages to the visible waste of resources on grand ideological projects and security; as suggested by Resource Curse Theory, minerals windfalls tend to encourage irresponsible behaviour by governments. On the other hand, certain businesses prospered, notably the Afrikaner business sector. All business benefited from the overall growth of the 1950s and 1960s, whilst niche players often did quite well even during the 1980s. Further, the South African businessmen, both English- and Afrikaans-speaking, were skilful in adapting to the difficult conditions brought about by apartheid, and in many cases they prospered. As highlighted by Business Systems Theory, embedded social ties and informal relations may help either support or compensate for formal regulatory pressures. Many of these general trends were particularly accentuated in the Western Cape. The fact that business protests against government policies were often more motivated by concerns as to future property rights and of social disorder, rather than human rights, does indeed raise serious moral issues. However, in helping encourage political reform, they may have made a positive contribution. This study is founded on three related strands of thinking within the political economy tradition, Resource Curse Theory, Regulation Theory and Business Systems Theory, with the emerging common ground between these three bodies of thought being highlighted. As suggested by Resource Curse Theory, non-mineral producing regions tend to be particularly adversely affected in mineral rich countries, and there is little doubt that the region bore all the costs of the collapse of the gold price in the 1980s, and lacked the deeper capital base of the now Gauteng region to cushion the shock. Whilst apartheid may, as we have seen, have served conservative sectors of agriculture and mining quite well for many years, it also involved large costs incurred through social engineering experiments and the increasing demands of the security establishment. Resource Curse Theory suggests that national economies become dangerously dependent on the vagaries of commodities markets, and that the process of institutional design and evolution is hampered by assumptions of easy money which may temporary resolve the negative consequences of any institutional shortcomings. The poor price of gold in much of the 1980s brought about a crisis in the system, and, there is little doubt that this contributed to the demise of the order. As suggested by Resource Curse Theory, the experience of the Western Cape, a region of the country poor in minerals, was often one of inefficient and wasteful state intervention, coupled with increasingly poor performance of non-mineral related industries. Indeed, the effects of the recession of the 1980s were most pronounced in non-mineral producing areas of the country, particularly in the Western Cape. Regulation Theory highlights that no set of institutions and practices is ever totally coherent and functional, but at specific times may work to promote both certain types of economic activity and overall growth. It is wrong to suggest that because an order only works for some players at specific times it is simply dysfunctional or does not work properly at all. However, over time, internal contradictions mount and the benefits diminish. A particular feature of the apartheid order was that some of its core benefits at its height were particularly concentrated on some players (segments of Afrikaner commerce and industry, mining and agriculture), whilst the costs were shared across a wider range of players, with a disproportionate burden being borne by the black majority. A further feature was that the costs were often indirect and spread over many years if the benefits were sometimes immediate: this would include the persistent dysfunctionality of much of the South African education system and the criminal ecosystem that was nurtured through sanctions busting. Internal contradictions and spreading dysfunctionality rarely leads to a conscious and coherent period of institutional redesign, but rather an incoherent, experimental and contested process, such as characterized late apartheid reforms, and, indeed, the post February-1990 negotiation process. Finally, again at a theoretical level, as Business Systems Theory highlights, it is important to take account of the formal and informal ties interlinking firms in different sectors in the region, and firms and government, and the extent to which regions within a particular country may follow very distinct developmental trajectories. The benefits and the costs of the system diffused unevenly in the region, giving many players both a stake in the existing order, and an interest in some or other type of reform.

Chinese tourists' intentions to visit South Africa: an extended model of the theory of planned behaviour

- Description: The South African National Department of Tourism has recently initiated the National Tourism Sector Strategy aimed at developing a sustainable tourism economy, and making the country a Top 20 global tourism destination by 2020.China is one of South Africa’s major non-African sources of tourist arrivals. To ensure a growing share of this booming market, South African tourism scholars and practitioners have to pay close attention to the behaviour of Chinese outbound tourists, particularly their destination choice behaviour. The Theory of Planned Behaviour (TPB)– an extension of the Theory of Reasoned Action (TRA)– can serve as a basis for researching destination choice. According to the TPB literature, intention is the most immediate and important determinant of behaviour. Three direct predictors of intention, namely, attitude, subjective norms, and perceived control, are functions of latent behavioural, normative, and control beliefs, respectively. The TPB is parsimonious but open to the inclusion of additional predictors if there is evidence that these predictors may explain a significant proportion of the variance in intention and behaviour after the basic predictors (attitude, subjective norms, and perceived control) have been accounted for. The current research successfully extended the TPB model for predicting potential Chinese tourists’ intentions to visit South Africa by adding two additional variables: travel motivation and travel constraints. The push-pull motivation framework discussed in the study postulates that people travel because they are pushed by internal forces (inner needs) and pulled by external forces (destination attributes). Typical barriers to travel include intrapersonal, interpersonal, and structural constraints. The new model makes an important contribution to the literature on destination choice, and provides South Africa’s destination marketers with suggestions for attracting and serving Chinese tourists. In addition, the research shows that both travel motivation and travel constraints can be used as bases for segmenting the outbound Chinese tourist market interested in visiting South Africa. A survey approach and a structured questionnaire distributed electronically to the online panel members of a Chinese market research company were instrumental in collecting the empirical data for the study. The questionnaire was originally written in English and translated into Chinese (Mandarin) via a blind translation-back-translation method. Attitude, subjective norms, perceived control, and visit intention were all operationalised as unidimensional and used scales adapted from previous studies. New scales were developed for travel motivation and travel constraints– both operationalised as multidimensional. Quota sampling, used to identify respondents aged 18 or older and living in Beijing, Shanghai, and Guangzhou, resulted in 630 usable questionnaires obtained from 1,510 sent invitation e-mails, yielding a response rate of 41.7%. The raw data collected were prepared through the sequential steps of editing, coding, and filing, and then analysed using both descriptive and inferential statistics. Descriptive analysis suggested that broadening personal horizons, viewing the natural scenery, and seeing something different were the top motives for visiting South Africa, while language, fear of crime, and lack of travel companions were the top barriers to visiting South Africa. According to the factor analysis, travel motivation had three underlying dimensions – learning, escape, and aesthetics and appreciation, while operational, risk and fear, and social barriers were three underlying dimensions of travel constraints. Regression analysis showed that the proposed extended TPB model had higher predictive power for visit intention than both TRA and TPB models; the basic predictors – attitude, subjective norms, and perceived control – all had a significant impact on visit intention; and in terms of the additional predictors, learning, operational constraints, and social constraints had a significant impact on visit intention. The analysis of variance indicated that travel frequency and age were the most profound background factors with an influence on the extended TPB model. Finally, cluster analysis resulted in two market segments with distinct profiles, that is, High-Motivation/ Low-Constraint (HMLC) tourists and Low-Motivation/High-Constraint (LMHC) tourists. Based on the theoretical and empirical findings of the current research, it is recommended that destination marketers in South Africa: advertise specific benefits of touring South Africa, namely, increasing knowledge, relieving stress, and enjoying high environmental quality, to advance Chinese residents’ perceptions of the country; develop tourism experiences that can be taken in a week or shorter to cater for the unique annual leave and public holiday policy in China; launch a media relations campaign in China to ensure that the facts about South Africa are communicated without distortion; collaborate with other destination stakeholders such as government and businesses, to actively attract and retain Chinese tourists for example by educating the public about Chinese culture and training employees to improve the quality of service; target the HMLC tourists via the Internet (particularly the social media) and by developing holiday packages that include activities related to cultural tourism, rest and relaxation, and nature-based tourism; and target the LMHC tourists by cooperating with local travel agencies and by developing holiday packages that highlight the diversity of tourism activities and offer value-added products/services.

Comparison of the population growth potential of South African loggerhead (Caretta caretta) and leatherback (Dermochelys coriacea) sea turtles

- Description: A beach conservation programme protecting nesting loggerhead (Caretta caretta) and leatherback (Dermochelys coriacea) sea turtles in South Africa was started in 1963. As initial numbers of nesting females were low for both species (107 loggerheads and 24 leatherbacks) it was proposed that the protection of eggs, hatchlings and nesting females along the nesting beach would induce population growth and prohibit local extinction. Today, 50 years later, the loggerhead population exceeds 650 females per annum, whereas the leatherback population counts about 65 nesting females per year. The trend for leatherback turtles is that the population has been stable for about 30 years whereas loggerheads are increasing exponentially. Thus, this thesis investigated several life-history traits to explain the differing responses to the ongoing beach conservation programme. Reproductive output and success were assessed for both species; it was hypothesised that environmental conditions are sub-optimal for leatherback turtles to reproduce successfully. It was ascertained that nesting loggerhead females deposit larger clutches than leatherbacks (112 ± SD 20 eggs and 100 ± SD 23 eggs, respectively), but that annual reproductive output per individual leatherback female exceeds that of loggerhead turtles (±700 eggs and ±448 eggs, respectively) because they exhibit a higher intra-seasonal nesting frequency (leatherbacks n = 7 and loggerheads n = 4 from Nel et al. 2013). Emergence success (i.e. the percentage of hatchlings produced) per nest was similar for both species (loggerhead 73.6 ± SD 27.68 % and leatherback turtles 73.8 ± SD 22.70 %), but as loggerhead turtles nest in greater numbers, i.e. producing more hatchlings per year, the absolute population growth potential favours the loggerhead turtle. The second factor investigated was sex ratio because sea turtles display temperature-dependent sex determination (TSD) where extreme incubation temperatures can skew the sex ratio (i.e. feminising or masculinising a clutch). It was suspected that leatherback turtles are male-biased as this is the southern-most rookery (for both species). Further, leatherback nests are generally closer to the high tide mark, which might induce a cooling effect. Standard histological techniques were applied to sex hatchlings and a generalized linear model (GLM) was used to approximate annual sex ratio. Loggerhead sex ratio (2009 - 2011) was estimated at 86.9 ± SE 0.35 % female-biased; however, sufficient replication for the leatherback population was only obtained for season 2010, which indicated a 97.1 % (95 % CI 93.3 - 98.7) female bias. Both species are, thus, highly female-biased, and current sex ratio for leatherback turtles is not prohibiting population growth. Current sex ratios, however, are not necessarily indicative of sex ratios in the past which would have induced present population growth. Thus, to account for present population growth profiles, sex ratios from the past needed to be ascertained. Annual sex ratios (1997 - 2011) were modelled from historical air and sea surface temperatures (SSTs) but no significant change over time was obtained for either loggerhead or leatherback turtles (linear regression; p ≥ 0.45). The average sex ratio over this 15-year period for the South African loggerhead turtle was approximated at 77.1 ± SE 3.36 % female-biased, whereas leatherbacks exhibited a 99.5 ± SE 0.24 % female bias. Re-analysing data from the mid-80s by Maxwell et al. (1988) also indicated a 77.4 % female bias for the South African loggerhead population. It is, therefore, highly likely that sex ratios of the South African loggerhead and leatherback sea turtle populations have been stable for at least three decades and are not accountable for the differing population growth profiles as they are displayed today. Another possibility that could explain the opposed population growth profiles is the time taken for animals to replace themselves, i.e. age at maturity. It was suspected that age at maturity for the South African loggerhead turtle is comparable with that for leatherbacks. Using data from a 30-year mutilation tagging experiment (i.e. notching), age at first reproduction for South African loggerhead females was estimated. Results ranged broadly but a mean of 36.2 ± SD 7.71 years was obtained using a Gaussian distribution. Age at reproduction of the South African leatherback turtle was not determined but the literature suggests a much younger age of 13.3 - 26.8 years (Zug & Parham 1996, Dutton et al. 2005, Avens et al. 2009, Jones et al. 2011). Therefore, population growth would favour leatherback turtles as they exhibit a much shorter generation time. Finally, it was concluded that all life-history parameters investigated favour leatherback turtles, yet loggerheads are displaying population growth. However, as there were no obvious constraints to population growth on the nesting beach, it is suspected that population growth of the South African leatherback turtle is either unobserved (due to inadequate monitoring not capturing sufficient numbers of nesting events to establish a trend) or that population growth is prohibited by some offshore factor such as industrial fisheries (or some other driver not yet identified). Monitoring should, thus, be expanded and offshore mortality monitored as the leatherback population nesting in South Africa is still critically endangered with nesting numbers dangerously low.

It was suspected that leatherback turtles are male-biased as this is the southern-most rookery (for both species). Further, leatherback nests are generally closer to the high tide mark, which might induce a cooling effect. Standard histological techniques were applied to sex hatchlings and a generalized linear model (GLM) was used to approximate annual sex ratio. Loggerhead sex ratio (2009 - 2011) was estimated at 86.9 ± SE 0.35 % female-biased; however, sufficient replication for the leatherback population was only obtained for season 2010, which indicated a 97.1 % (95 % CI 93.3 - 98.7) female bias. Both species are, thus, highly female-biased, and current sex ratio for leatherback turtles is not prohibiting population growth. Current sex ratios, however, are not necessarily indicative of sex ratios in the past which would have induced present population growth. Thus, to account for present population growth profiles, sex ratios from the past needed to be ascertained. Annual sex ratios (1997 - 2011) were modelled from historical air and sea surface temperatures (SSTs) but no significant change over time was obtained for either loggerhead or leatherback turtles (linear regression; p ≥ 0.45). The average sex ratio over this 15-year period for the South African loggerhead turtle was approximated at 77.1 ± SE 3.36 % female-biased, whereas leatherbacks exhibited a 99.5 ± SE 0.24 % female bias. Re-analysing data from the mid-80s by Maxwell et al. (1988) also indicated a 77.4 % female bias for the South African loggerhead population. It is, therefore, highly likely that sex ratios of the South African loggerhead and leatherback sea turtle populations have been stable for at least three decades and are not accountable for the differing population growth profiles as they are displayed today. Another possibility that could explain the opposed population growth profiles is the time taken for animals to replace themselves, i.e. age at maturity. It was suspected that age at maturity for the South African loggerhead turtle is comparable with that for leatherbacks. Using data from a 30-year mutilation tagging experiment (i.e. notching), age at first reproduction for South African loggerhead females was estimated. Results ranged broadly but a mean of 36.2 ± SD 7.71 years was obtained using a Gaussian distribution. Age at reproduction of the South African leatherback turtle was not determined but the literature suggests a much younger age of 13.3 - 26.8 years (Zug & Parham 1996, Dutton et al. 2005, Avens et al. 2009, Jones et al. 2011). Therefore, population growth would favour leatherback turtles as they exhibit a much shorter generation time. Finally, it was concluded that all life-history parameters investigated favour leatherback turtles, yet loggerheads are displaying population growth. However, as there were no obvious constraints to population growth on the nesting beach, it is suspected that population growth of the South African leatherback turtle is either unobserved (due to inadequate monitoring not capturing sufficient numbers of nesting events to establish a trend) or that population growth is prohibited by some offshore factor such as industrial fisheries (or some other driver not yet identified). Monitoring should, thus, be expanded and offshore mortality monitored as the leatherback population nesting in South Africa is still critically endangered with nesting numbers dangerously low.

- Description: This study explores, through digital storytelling, the experiences of HIV- and AIDS-related stigma of rural community secondary school learners. HIV- and AIDS-related stigma is seen as an impediment to a proficient response to HIV and AIDS in communities, also rural communities, and requires addressing. The rural community in which the research is undertaken is particularly hard hit by HIV and AIDS. Learners’ experiences of HIV- and AIDS related stigma could therefore inform how school and community could engage with HIV- and AIDS-related stigma and how they could address it in a constructive way. The study attempts to respond to two research questions: What can digital storytelling reveal about secondary school learners’ experiences of HIV- and AIDS-related stigma in schools in a rural community? How can digital storytelling enable secondary school learners in school in a rural community to take action to address stigma? This qualitative study is positioned within a critical paradigm, and employs a community-based participatory research strategy. Twelve Grade 8 and 9 male and female learners aged 15 to 18 years, from two secondary schools in rural Vulindlela district of KwaZulu-Natal, South Africa, who experienced, witnessed or heard about HIV- and AIDS-related stigma participated. Digital storytelling, a visual participatory method, was used to generate the data, and this was complemented by group discussion and written pieces completed by the participants in reflection sessions. The thematic analysis of the data made use of participatory analysis: the analysis of the digital stories was done by the participants while the overarching analysis was done by the researcher. This study, located in the field of the Psychology of Education, is informed by the theoretical framework of symbolic interactionism. In terms of the experienced stigma, it was found that living with HIV and AIDS and the related stigma is perceived as a ‘hardship’. The stigma is experienced on many levels: in the family, at school, and from friends and members of the community. It has an impact on the individual on an intrapersonal and interpersonal level. The young person is caught up in a vicious cycle of silent suffering since there are no reliable and trustworthy people with whom he or she can share these challenges. Some so-called traditional beliefs and customs such as not talking about sex, and practices like virginity testing, also fuel HIV- and AIDS-related stigma. The use of derogatory terms and the severe criticism of early sexual debut along with the gossiping which is used to spread the stigmatising statements further complicate the hardship experienced by young people. Digital storytelling was found to not only enable the learners’ voices to be heard but also to enable their taking charge of the stigma and thus create the space for critical participation in this research. The implications for the study are that the pervasive stigma that young people experience should be addressed at every level of the community. The stakeholders such as the families, school, educators, the King (Inkosi) and Chiefs (Indunas) of the area, relevant departments with that of Education taking the lead, must work hand-in-hand with the affected young people. Such collaboration may allow for the identification of the problem, for reflection on it, and also for the addressing of it. HIV- and AIDS-related stigma, while it has changed since the emergence of HIV, still is an issue that many HIV-positive individuals have to contend with. This stigma is, however, contextual and how the individual is stigmatised fits in with the language, meaning and thought that a community constructs around stigma. While digital storytelling enables the uncovering of particular stories of stigma that learners experience in the context of a school in a rural community, the digital storytelling in and of itself enables a change in the language, meaning and thought around stigma in its drawing on the specifics of the stigma as experienced in the community. Also, digital storytelling is about sharing stories about, and experiences of HIV- and AIDS-related stigma and how these stories can be used as part of the solution. If such stories can be told, people can spread them just as gossip is spread, but in this case such spreading would work towards positive social change. I claim that in order to confront the challenges raised by the perpetuation of stigma, efforts must involve the communities and must tap into their own experiences of perpetuating or enduring stigmatisation. Suggestions by the very same people from the community who are at the front line of perpetuating and /or suffering the stigma must be considered. This may also become one way of instantly communicating the research findings back to the community involved in the research. Using digital storytelling can ensure getting self-tailored, contextual, specific views on how HIV- and AIDS-related stigma is experienced but also how it could be addressed.

- Description: The main research question guiding this study is: “What strategies can be established to enhance parental involvement in primary schools in disadvantaged communities in the Northern Areas of Port Elizabeth”? To answer this question, this study examines parents’ and teachers’ practices concerning parental involvement in the Northern Areas of Nelson Mandela Metropolitan. Parents and teachers were purposely selected from participating schools. In this qualitative study, the researcher proposed strategies to enhance parental involvement at primary schools. Qualitative research methods, associated with phenomenological inquiry were employed to explore the life-world of the participants who have had personal experience with the phenomenon of parental involvement. Data was collected through semi-structured interviews with parents and teachers. This allowed the researcher to gather in-depth information about opinions, beliefs, practices and attitudes concerning the involvement of parents in their children’s education. Bronfenbrenner’s ecosystemic theory served as the theorectical framework of this investigation. Since this study is about parental involvement in primary schools educational policies like inclusive education as well as different models of parental involvement were investigated in the literature study. The results of the study indicated several barriers to the enhancement of parental involvement for instance communication barriers between parents and teachers. The researcher established four strategies for the enhancement of parental involvement and recommended that these strategies should be employed by schools and other stakeholders. She also made further recommendations for parents, teachers, school principals, Department of Basic Education and professionals in the community.

- Description: It is broadly accepted that there is a need for better security management and protocols for hostage incident management, there is currently a lack of basic empirical knowledge about the existing security management protocols with reference to existing policies, knowledge and the capability of International Non-Governmental Organisations (INGOs) to handle hostage incidents. Many INGOs have successfully managed high-profile hostage crises, but there is still a considerable level of uncertainty about the way these crises have been solved and the way their success can be seen in relation to other crises. This study aimed to understand how INGOs prepare themselves for hostage incidents, whether policies, procedures are in place, how they manage hostage situations, and also how INGO staff are trained and prepared. The methodology adopted for this study was qualitative and comprised of indepth interviews with sixteen INGOs and ten industry experts and a review of INGO documents, policies and plans. The study sheds light on some of the less talked-about aspects for INGO security management in general, as well as preparedness and responsibility towards their staff. The study suggests that while most organisations have a level of preparedness in place, enhancing each agency’s respective policies may assist the organisation in better management. The study also found that there is a higher use of ransom payment than expected, and that there is an increasing willingness to engage external expertise to assisting in managing a hostage crisis. The study makes several recommendations that may have policy implications, including pre-deployment hostile environment training, reviewing potential cooperation between INGOs and United Nations, and the use of external resources to assist in managing a hostage crisis. It also recommends a revision of existing negotiation models, as the current models are lacking in addressing protracted hostage cases. The establishment of an accurate database of incidents to allow for improved interpretation of trends and scope of hostage cases is also recommended.

- Description: Discourse characterising climate change has largely revolved around aspects within the realm of impact identification, mitigation and adaptation. Apparently, a burgeoning appetite to examine the role of indigenous knowledge (IK) now confronts the fronts of climate science, policy and practice. The surge in attention to localbased knowledge is attributed to growing challenges posed by change and variability in the climate system. This study argues that indigenous-based knowledge is capable of filling knowledge gaps and validating current understanding about climate change particularly at local levels. Essentially, the paucity of knowledge about local climatic events can be circumvented by engaging indigenous ‘scientists’ whose many years of direct contact with the environment have equipped them with the indispensable knowledge, skills and experiences to understand the same. Primarily, the thesis’ objectives were threefold. One, it captured useful indicators of climate change and variability from the understanding of the indigenous people, which can also be used to enhance understanding of climate change impacts.Two, it drew from the knowledge, experiences, skills and practices of the locals in order to inform appropriate community level mitigation and adaptation interventions. And, three, it highlighted the fact that knowledge of the indigenous people can be used to direct research on climate change. The study area (Muzarabani in Zimbabwe) experiences recurrent droughts and floods and its villagers rely predominantly on climate-sensitive livelihoods. As such, it was selected to provide a reliable case on IK practices and experiences of the people witnessing climatic events. The study was framed within an epistemological and methodological configuration of emancipatory pedagogy that looks at the generators of climate knowledge as ‘scientists’ in their own right. A qualitative elicitation interviewing technique involving in-depth discussions with traditional leaders and elderly knowledgeable citizens was conducted. The participants were selected through chain referrals until the level of theoretical saturation. In addition, directed field observations, document analysis and key informant interviews with other respondents selected through theoretical sampling enhanced the robustness of data acquisition methods. Group-based participatory data analysis and reflexive pragmatism also enhanced rigour and quality of research findings intended to balance between the strictures of the scientific audience and the views of the knowledge generators. Three key themes were derived from IK-climate change linkages as: indigenous based indicators of climate change, indigenous-based mitigation and indigenous based adaptation. A range of indigenous-based indicators identified pointed to a progressively drier climate with shorter growing seasons that are also punctuated by mid-season dry spells. A trend towards increased desiccation of water bodies (rivers, ponds and vleis) was further observed. There is also an upsurge in the abundance and pestiferous nature of Macrotermes spp, Quelea quelea and Acanthoplus discoidalis, which are most likely related to climate change. Some of these indicators closely match with those used in mainstream climate science and they also serve to understand climate change impacts at a finer local level of analysis. Indigenous-based mitigation is mainly driven by the notion of sacredness where the locals regard forestry, certain trees and vleis as sacrosanct. Tampering with these is believed to upset the spirits who have powers to influence climate. Opportunities associated with IK deployment in climate mitigation are understood from the viewpoint of enhancing greenhouse gas (GHG) sinks and that of reducing vulnerability to extreme climatic events. Specifically, this can be achieved through enhancing GHG sequestration through forestry and land-use management initiatives; that is, reducing emissions from deforestation and forestry related degradation (REDD+) and Land Use and Land-Use Cover and Forestry (LULUCF). These two are the dominant schemes adopted by the Intergovernmental Panel on Climate Change (IPCC) to govern climate mitigation. Indigenous disaster risk management (DRM) strategies abound in drought, famine, flood and violent storms through various forms such as Zunde raMambo, nhimbe, rain-making ceremonies and community early warning systems (EWS).The locals in Muzarabani are not passive observers of the changing climate system. Increasing environmental risks necessitates them to devise countermeasures for responding to climatic stimuli with the intention of minimising harm and/or enhancing the benefits brought about by the same. Thus, a portfolio of IK-based adaptation strategies best described as an assortment of short-term coping practices and longterm adaptive strategies were identified. These range from exploitation of ecosystem services, agricultural based interventions, riverine farming, traditional phonological knowledge (TPK) to migration. Therefore, it was revealed that community-based adaptation (CBA) can adequately leverage on IK to improve adaptive capacity and build community resilience against climate change. Clearly, the complementary role of indigenous-based knowledge cannot be disputed, given the demonstrated range of applications from identifying several indicators of change and variability in the climate system, examination of climate change impacts, to identification and assessment of mitigation and adaptation options. The study advises that exogenous climate interventions need to be congruent with indigenous based strategies to avoid maladaptation. To the climate research community therefore, it should be realised that IK is useful both as leads and as baseline knowledge for future work on the impacts of climate change, and in the assessment of climate interventions. In this regard, the remaining challenge is to formulate a framework of constructive dialogue between indigenous scientists and conventional scientists so as to make sure that the mutual benefits of the two knowledge forms are adequately harnessed. Handled well, such collaborative effort would ensure enhanced climate change knowledge for successful mitigation and adaptation strategies. Handled poorly, there is a risk that the developmental needs of communities exposed to climatic events would not be addressed.

- Description: The Internet of Things (IoT) environment involves the interaction of numerous ‘things’. These ‘things’ are embedded with different kinds of technologies such as RFID technology, NFC technology and sensors. This causes IoT to bring into play many security risks apart from the ones that already exist in the current Internet, for example, embedded RFID tags can be easily triggered and send their content which could be private information. IoT also introduces internal attacks such as on-off attack, bad mouthing and white washing attacks into networks that already exist. These internal attacks cannot be solved by hard security mechanisms such as cryptographic algorithms and firewalls because they guarantee total trust. This eliminates uncertainty which should always be available where trust exist. That is, hard security mechanisms enable IoT ‘things’ to either trust another ‘thing’ completely or not and this makes them unsuitable for the IoT environment. When objects in any network are communicating, there is some element of uncertainty. Also, hard security mechanisms such as public key cryptography cause communication overheard in the already resource-constrained IoT devices and these conventional cryptography methods cannot deal with internal attacks. This brings about the need for a middleware that includes functions that will manage trust, privacy and security issues of all data exchange, communications and network connections. For IoT to be successful, the provision of trust, security and privacy measures are essential. Trust management may enhance the adoption and security measures in IoT. Trust helps in identifying trustworthy ‘things’ in the network and give ‘things’ in the network the ability to reason in all aspects concerning trust in the environment. Trust can be administered through a trust management model. This research notes that most of the trust models that have been proposed fail to address scalability challenges and lack suitable computation methods. It is on that premise that this research focuses on developing a suitable trust model for the IoT environment. The research also introduces new ways of creating relationships in IoT. This enables the creation of new cooperation opportunities in the environment. In overall, this research aimed to design and develop a generic trust and authority delegation model for the heterogonous IoT environment that is scalable and generalized to cater for the heterogeneous IoT environment. This research was conducted in three phases. The first phase reviewed literature in order to identify outstanding issues in IoT trust management and also identify the suitable computational method. This provided a critical analysis of different computational methods highlighting their advantages and limitations. In the second phase of the research, the proposed trust model was designed and tested. In the last phase, the feasibility of the proposed model was evaluated. The proposed model is based on fuzzy logic. Fuzzy logic was selected for trust computation because it is able to imitate the process of the human mind through the use of linguistic variables and it can handle uncertainty. The proposed model was tested in a simulated environment. The simulation results showed that the proposed model can identify selfish and malicious entities effectively. The results also showed that the model was able to deal with different types of behaviours of entities. The testing proved that the proposed trust model can support decision making in IoT based on trust. The results from the evaluation show that this research ameliorates the design and development of trust management solutions for the IoT environment.

- Description: The Internet of Things (IoT) environment involves the interaction of numerous ‘things’. These ‘things’ are embedded with different kinds of technologies such as RFID technology, NFC technology and sensors. This causes IoT to bring into play many security risks apart from the ones that already exist in the current Internet, for example, embedded RFID tags can be easily triggered and send their content which could be private information. IoT also introduces internal attacks such as on-off attack, bad mouthing and white washing attacks into networks that already exist. These internal attacks cannot be solved by hard security mechanisms such as cryptographic algorithms and firewalls because they guarantee total trust. This eliminates uncertainty which should always be available where trust exist. That is, hard security mechanisms enable IoT ‘things’ to either trust another ‘thing’ completely or not and this makes them unsuitable for the IoT environment. When objects in any network are communicating, there is some element of uncertainty. Also, hard security mechanisms such as public key cryptography cause communication overheard in the already resource-constrained IoT devices and these conventional cryptography methods cannot deal with internal attacks. This brings about the need for a middleware that includes functions that will manage trust, privacy and security issues of all data exchange, communications and network connections. For IoT to be successful, the provision of trust, security and privacy measures are essential. Trust management may enhance the adoption and security measures in IoT. Trust helps in identifying trustworthy ‘things’ in the network and give ‘things’ in the network the ability to reason in all aspects concerning trust in the environment. Trust can be administered through a trust management model. This research notes that most of the trust models that have been proposed fail to address scalability challenges and lack suitable computation methods.

- Description: This psychobiography is focussed on the life of Pope John Paul II, whose historical personage epitomises the redemptive theme of triumph over tragedy and eternal hope. A phenomenological approach to the study allowed the researcher to observe the subject’s lived experience through the theoretical lens of Erik Erikson’s psychosocial development theory as well has having his faith development illuminated by Fowler’s faith development theory. Together, these theories highlighted significant aspects of Pope John Paul II’s personality development, for the greater purpose of uncovering the significance of his historical personage by reconciling his spiritual, political and academic attributes. This psychobiographical undertaking was grounded in qualitative research in the form of a single case. Two methodological strategies were used in this study. Firstly, Alexander’s model was used to organise, extract, prioritise and analyse data. The indicators of salience ensured that all significant parts of biographical data were carefully considered for analysis. Guba’s criteria for trustworthiness guided the methodology to ensure reliable data extraction and interpretation. Posing specific questions to the data enabled the researcher to extract units of analysis relevant to the aim of the study. Secondly, the use of conceptual frameworks and matrices enabled the longitudinal exploration, categorisation and description of the stages of psychosocial and faith development. The findings of this psychobiographical study of Pope John Paul II strongly support the importance of Erikson’s (1950) theory in understanding the processes of personality development in an individual life. In this psychobiographical study, the complex process of adaption and growth was highlighted by Erikson’s (1950) theory and placed periods of Pope John Paul II’s development in context. This study also demonstrated that gaining meaning in life through faith (Fowler, 1981) provides the individual with greater internal support when adjusting to life changes. Furthermore, greater intentionality on the part of therapists to thread faith and spirituality into their practice, is evidence of the eugraphic impact of this study.

- Description: South Africa has experienced a notable increase in adolescent drug use during the country’s transition from apartheid to democracy (Central Drug Authority [CDA], 2006). These findings are verified by epidemiological studies and two national youth risk behaviour surveys, highlighting the need for effective drug prevention interventions. Whilst drug use spans across age, gender and social strata, the rapid increase in both legal and illicit drug use among adolescents in the Northern Areas communities of Port Elizabeth has been particularly pronounced. The South African Community Epidemiology Network on Drug Use (SACENDU) statistics, which reflects on racial demographics in accordance with the Population Registration Act of 1950 (South Africa, 1950), reports that, in the year 2011, the ‘Coloured’ population constituted 62 percent of those individuals seeking treatment for drug abuse, compared to 15 percent ‘African’ treatment seekers in Port Elizabeth (Dada, Plüddemann, Parry, Bhana, Vawda & Fourie, 2012:44). Furthermore, methamphetamine use by persons under the age of 20 years in Port Elizabeth increased fivefold in a three-year period, i.e. from 7 percent in 2008 to 39 percent in 2011 (Dada et al., 2012), with the ‘Coloured’ population group accounting for the majority of methamphetamine users. These statistics reinforce a long-standing racial stereotype that associates ‘Coloured’ racial identity with an enhanced susceptibility to drug use. The National Drug Master Plan (South Africa, 2012a), and the Prevention of and Treatment for Substance Abuse Act (Act no 70 of 2008) propose that drug prevention programmes should address the values, perceptions, expectations and beliefs that the community associates with drug abuse (South Africa, 2008b). This view emphasises the importance of drug preventions interventions that are culturally sensitive and contextually relevant. The current study was guided by two conceptual frameworks, i.e. the Social Constructionist Framework and the Ecological Risk/Protective Resilience Framework, and focused on the Northern Areas of Port Elizabeth, a historically marginalised community inhabited by a predominantly ‘Coloured’ indigenous/ethnic group. The goal of the study was to enhance understanding of the socio-cultural meaning attributed to cultural identity, drug use, non-use and drug prevention in the Northern Areas of Port Elizabeth, with the view to developing guidelines for drug prevention interventions that are culturally sensitive and contextually relevant. The following objectives were formulated in order to achieve the goal of the study: • To explore adolescent narratives regarding the constructs ‘Coloured’, drug use, non-use and drug prevention programmes of three distinct groups of adolescents (drug users, non-users, and TADA peer mentors) from the Northern Areas. • To explore and describe the social service practitioners’ (social workers and social auxiliary workers’) constructions of drug use, non-use and drug abuse prevention in relation to adolescents from the Northern Areas, and how such constructions inform the drug prevention services rendered to adolescents from these communities. • To review the data collected from the adolescent narratives and the social service practitioners’ reflections on their drug prevention programmes against existing theory and models for drug prevention. • To synthesise the above information with a view to developing guidelines for culturally sensitive drug prevention programmes relevant and responsive to the specific social constructions of adolescents from the Northern Areas. A qualitative research approach, located in a narrative tradition of inquiry research design, was employed to achieve the goal of the study (Riessman, 2008). The study was conducted in two phases. The first phase involved an empirical study with the four sample groups (i.e. adolescent drug users, adolescent non-drug users, Teenagers against Drug Abuse [TADA] peer mentors and social service professionals (i.e. social workers and social auxiliary workers)). Phase two involved the co-construction of the practice guidelines for culturally sensitive and contextually relevant drug prevention interventions. Phase one started with the informal exploration of community stakeholders’ views on the identified research problem and the process of gaining access to the research population. Several gatekeepers (i.e. teachers, social workers, the Families Against Drugs [FAD] Support Group representatives, a minister of religion and a community stakeholder) were engaged to assist in recruiting participants from the four sample groups. A non-probability purposive sampling method was employed to purposively recruit 29 adolescent non-drug users and ten adolescent peer mentors (via the TADA Programme at one school). The same sampling method, followed by a snowball sampling technique, was employed to recruit the two remaining sample groups of ten adolescent drug users (in the recovery process) and nine social workers and social auxiliary workers respectively. The sample sizes were determined by the principle of data saturation.The data generation method used in respect of the non-users took the form of semi-structured written narratives, administered in a group context during school time, followed by a second round of data generation. The life-grid (Wilson, Cunningham-Burley, Bancroft, Backett-Milburn & Masters, 2007:144), a qualitative visual tool for mapping important life events, was employed to guide the co-construction of the biographical narratives generated during the individual semi-structured interviews with the sample of adolescent drug users. Focus group interviews were used to enhance an understanding of the peer mentors and social service practitioners’ views on the construct ‘Coloured’ and their existing drug prevention programmes. Each of the individual and focus group interviews was audio-recorded, transcribed and complemented by the field notes. Informal data gathering occurred through participant observation of two drug prevention programmes, attendance of a FAD Support Group meeting, and interviews with community volunteers and the South African Police Services (SAPS) Youth Development Forum. Both the content and the context of the narratives were analysed to arrive at the research themes, sub-themes and categories. The content of the narratives was analysed by employing categorical content analysis, whilst the form of the narratives (i.e. how the stories were told) was analysed by using the socio-cultural approach to narrative analysis (Grbich, 2007:130). The journey metaphor emerged from the adolescent drug users’ narratives, depicting a prototypical storyline of a drug use journey, starting with experimentation and culminating in abuse and dependence for some and an early exit from the journey for others. The conclusions that can be drawn from these findings illuminate key protective factors and processes at a multisystemic level that can be strengthened to enhance the adolescents’ resistance to drug use and/or delay the onset of use. Embedded in the participants’ narration of the drug use journey were nuances relating to internalised stereotypes of ‘White’ supremacy and ‘Coloured’ inferiority as an explanatory framework for venturing onto and prolonging the journey.The two themes that emerged during the process of content and narrative analysis of the qualitative data (from both adolescent drug users and non-users) were as follows: Constructing drug use as a ‘Coloured’ phenomenon and reconstructing ‘Coloured’ identity; Risk and protective factors located at individual, family, peer, school, community and societal domains. The four themes that emerged during the data analysis of the peer mentors and social service practitioners’ narratives were as follows: Construction of ‘Coloured’ identity; socio-cultural meaning construction about the reasons for drug use amongst adolescents from the Northern Areas; description of drug prevention services rendered in the Northern Areas; and reflection on barriers to rendering drug prevention interventions.

- Description: The current global recession has highlighted the fragile banking and related systems exposure to risks and acts of fraud. As a result of the ever changing information technology environment, where the internet has become an important retail sector channel, new fraud challenges are being encountered. The rapid growth in credit and cheque card transactions as a payment mechanism has led to an increase in card fraud. Approximately 70% of consumers utilising credit and cheque cards, as payment mechanisms, are significantly concerned about fraud (McAlearney, 2008). Additionally, credit card fraud has broader negative implications, such as funding organised crime, international narcotics trafficking and even the financing of terrorist activities. The first section of this study develops classification models that will improve on existing methods used to detect fraud and, as a result thereof, reduce the number of fraudulent transactions. Using confidential data obtained from a South African Bank, logistic regression and scoring techniques have been combined to develop a classification model that improves on the existing fraudulent identification methods. Using the methods developed in this study, a higher percentage of fraudulent transactions are classified correctly when compared to discriminant analysis, a method often used to identify fraudulent transactions. These models enable the banking business to identify demographic, socio-economic and banking-specific determinants which contribute significantly towards fraudulent transactions. The early detection methods will allow banks to put in place measures that will reduce the occurrence of fraudulent transactions on customer’s cards. The second section involves understanding how card holders and merchants contribute towards the occurrence of fraudulent incidents. This was achieved through two surveys which were carried out in the Johannesburg metropolitan area. These surveys aimed at understanding the perceptions of card holders and merchants with regard to aspects pertaining to card fraud contributed towards the occurrence of card fraud. Multinomial logistic regression (MLR) is used to classify card holders and merchants according to their likelihood of experiencing card fraud incidents. These results are based on their perceptions of certain aspects related to card fraud as obtained from the survey instruments.

- Description: This work presents a broad overview of the successful development of friction taper stud welding (FTSW) in 25mm thick AA6082-T6 sections. It covers the selection of geometry and process parameters, the development of data logging equipment, energy input results and interpretations. Research was carried out to develop the FTSW process for application in 25mm AA6082-T6 sections. The development and application of the FTSW process addresses the need to fill blind holes in thick aluminium sections for the repair of incorrectly drilled holes, friction stir welding exit holes and defects in critical components. During welding, frictional torque, rotational speed, axial force, near interface temperature of the tapered hole and welding time was recorded. This data was used to calculate energy input and energy input rates throughout a weld, enabling the effect of process parameters to be linked to energy, temperature, microhardness and static joint strength. Results of preliminary experiments are included in the study that were used for the design of a process parameter test window for FTSW in AA6082-T6, as no parameters were available to indicate a starting point for the research. The effect of process parameters on the static joint strength at the base of the tapered hole are presented; using a parallel sided stud and tapered hole configuration. This addresses one of the pressing issues facing FTSW of AA6082-T6, namely the lack of bonding at the bottom of the blind hole. A final process parameter matrix is designed based on the process development welds and is presented and discussed. In addition, the use of a non-consumable heat sink was investigated to prevent the premature collapse of the stud during welding and was shown to be critically important to the FTSW of AA6082-T6. To achieve good sidewall bonding a hole taper angle of 60° is required, this having been shown during visual evaluation of development welds. Stud taper angles between 2° and 5° less than the taper angle of the hole were identified as the range within which good FTSW can be made. With this geometry, at no stage during welding did the body of the stud shear off from the weld interface due to softening, thereby preventing collapse of the stud and formation of poorly bonded regions at the sidewall of the hole. The absence of shearing off of the weld interface during plunge was shown to be a good indicator of appropriate geometry and can be linked to welds made with high hole and stud taper angles and high axial force ramp up rates. The large hole and stud diameter relative to the depth of the hole and the large taper angle of the hole further aid in keeping the weld nugget rotating in the hole, promoting plasticization of the sidewall. Axial force ramp up rate was found to be the main critical success factor in an AA6082-T6 FTSW. Without control of this parameter the body of the stud will heat and detrimentally soften during plunge. It was established that good FTSW in AA6082-T6 cannot be made without the use of preheat to overcome the heat dissipation during welding, and is directly linked to improved energy input characteristics. Energy input as well as energy input rate were directly linked to static tensile strength and softening in the HAZ. The angle of the stud has been related to the energy input rate limit of the stud body, with increasing stud taper angles enabling the stud to withstand a higher energy input rate, allowing the weld interface to propagate up the hole at a slower rate, promoting plasticization of the sidewall. This study has successfully made good FTSW in 25mm thick AA6082-T6, in a 60°, 20mm deep tapered hole. Process parameters and ranges that produce FTSW exhibiting the required characteristics were identified by this study.

The effect of process parameters on the static joint strength at the base of the tapered hole are presented; using a parallel sided stud and tapered hole configuration. This addresses one of the pressing issues facing FTSW of AA6082-T6, namely the lack of bonding at the bottom of the blind hole. A final process parameter matrix is designed based on the process development welds and is presented and discussed. In addition, the use of a non-consumable heat sink was investigated to prevent the premature collapse of the stud during welding and was shown to be critically important to the FTSW of AA6082-T6. To achieve good sidewall bonding a hole taper angle of 60° is required, this having been shown during visual evaluation of development welds. Stud taper angles between 2° and 5° less than the taper angle of the hole were identified as the range within which good FTSW can be made. With this geometry, at no stage during welding did the body of the stud shear off from the weld interface due to softening, thereby preventing collapse of the stud and formation of poorly bonded regions at the sidewall of the hole. The absence of shearing off of the weld interface during plunge was shown to be a good indicator of appropriate geometry and can be linked to welds made with high hole and stud taper angles and high axial force ramp up rates. The large hole and stud diameter relative to the depth of the hole and the large taper angle of the hole further aid in keeping the weld nugget rotating in the hole, promoting plasticization of the sidewall. Axial force ramp up rate was found to be the main critical success factor in an AA6082-T6 FTSW. Without control of this parameter the body of the stud will heat and detrimentally soften during plunge. It was established that good FTSW in AA6082-T6 cannot be made without the use of preheat to overcome the heat dissipation during welding, and is directly linked to improved energy input characteristics. Energy input as well as energy input rate were directly linked to static tensile strength and softening in the HAZ. The angle of the stud has been related to the energy input rate limit of the stud body, with increasing stud taper angles enabling the stud to withstand a higher energy input rate, allowing the weld interface to propagate up the hole at a slower rate, promoting plasticization of the sidewall. This study has successfully made good FTSW in 25mm thick AA6082-T6, in a 60°, 20mm deep tapered hole. Process parameters and ranges that produce FTSW exhibiting the required characteristics were identified by this study.

- Description: This research study explored the appropriate sustainable governance management systems for South African socio-economic conditions. This was achieved by investigating the current governance and management of water boards in performing their business and water services provisioning at municipal level. Municipalities are the third sphere of government in South Africa and are found at local levels of governance. They are businesses that provide running water as legislated by the Constitution of the Republic of South Africa, 1996. Water boards are public institutions established in terms of the Water Services Act, 108 of 1997 (WSA) and listed as Schedule 3 part B: National Government Business Enterprise in terms of the Public Finance Management Act 29 of 1999. They are accountable to the national government through the Department of Water Affairs. Their responsibility is to support municipalities where water-provisioning challenges are eminent. They report annually to national parliament on their performance within a specific financial year. Water boards are currently able to perform their operations in selected jurisdictions as contracted by municipalities. They are struggling in managing and governing their water business while striving to achieve improvements in water service coverage, operating efficiency and service delivery. The aim of the research study was to investigate areas affecting the sustainability of governance management systems for water boards in relation to the improvement of service delivery in South Africa. The analysis of age and gender factors and the conditions affecting governance are explored. The research used the qualitative and quantitative methods to analyse the research questions. Prior to the commencement of the study, the researcher performed an intensive desktop study involving the use of dated and recently published material related to governance and management of the water institutions in developed and developing countries. During the desktop study, national and international accredited journals were prioritised to obtain related and relevant similar information to the water governance and management of water institutions. In addition, a case study was undertaken in Ficksburg in which water boards provided an intervention in resolving the water crisis, since the provision of water is a basic service at local government. This area experienced both water shortage and a poor quality of water. With regard to qualitative methodology, participatory forums were used to delineate the research context and premise. The study population consisted of individuals who were in the business of water boards with special reference to water management and board of directors for a population of 1 000. Of the 500 questionnaires sent out, 419 were returned. The data were analysed using the statistical software package, Statistical Package for Social Sciences (SPSS). The results and recommendations are presented based on the identified objectives of the study. The study’s findings provide information for transformation and improvement in the performance of water boards in South Africa when striving for sustainability in management and governance. The findings reveal the need for improvements in the involvement of females in the business of the water boards. The findings confirm the outcomes of previous studies regarding the slow implementation of affirmative action and transformation processes as required by legislation. Furthermore, the results reveal that the factors and conditions affecting sustainability of the water boards need to be prioritised to improve the management and governance aspects of water boards. These include the appropriate selection of members of the boards of directors, water boards' committees that are guided by legislation in their operations and the maintenance of proper financial management (collection of revenue, implementation of appropriate financial strategies and striving for positive clean audit). Water boards are encouraged to strengthen their intergovernmental relations in order to make their mandate known across all spheres of government. Service delivery should be approached “from source to tap and tap to source” to promote high-quality provision of water. The water boards should be accountable to the municipalities for the provision of delegated operations. The Department of Water Affairs exercises an oversight role to ensure the sustainable provision of the services. However, the study concludes that without a strong management and a sustainable governance approach, water boards will not be able to carry out its water developmental mandate. The practical framework that was developed in this study provides management and governance tools for sustained provisioning of water to advance transformational and developmental needs and the application of legislations. The results in the study have a direct impact on the codes of practice and regulations on employment equity in implementing the Employment Equity Act of 1998, Intergovernmental Relations Act of 2005, Companies Act of 2008, National Water Act of 1998, and Water Services Act of 1997. Therefore, the practical implementation of this framework will enhance water as a transformational and developmental feature in addressing the social, environmental and economic services.
