- Description: sustained multiple concussions may be at risk of cumulative impairment. The role of neuropsychological testing in the management of sports-related concussion is a contentious and challenging issue which has gained credibility given the lack of clear and well-established guidelines pertaining to the diagnosis, assessment and return-to-play decisions following concussion. Despite various traditional paper and pencil tests being shown to be effective indicators of postconcussive neuropsychological dysfunction, testing has not been widely implemented, due to time- and labour-demands. ImPACT, a computer-based neuropsychological assessment instrument, has been recognised as a valid and reliable tool in the monitoring of athletes' symptoms and neurocognitive functioning preseason and postconcussion. As a part of larger-scale concussion research conducted on top-team university rugby players, this is an in-depth case study conducted on a 20-year old participant with a history of multiple concussions, who was referred following a concussion sustained during the season. The objectives of the study were: (i) to determine the sensitivity of ImPACT versus WAIS-III Digit Span and Trail Making Test during the acute postconcussive phase; and (ii) to examine the sensitivity of ImPACT versus a comprehensive battery of neuropsychological tests to possible residual deficits as a result of the multiple concussions. ImPACT was determined to be more sensitive to acute postconcussive impairment following concussion than Digit Span and Trail Making Test. Furthermore, the ImPACT preseason baseline scores appear to be sensitive to neurocognitive dysfunction, possibly due to cumulative concussive injuries.

- Description: The purpose of this study is to explore and discuss the use of teacher modification strategies by a high school teacher in the Eastern Cape province of South Africa in an English second language classroom. This teacher does not share the mother tongue of the learners. Unlike other teachers who resort to code switching when teaching L2 learners, this particular educator does not have that liberty. Code switching has been found to be a useful strategy for teaching and learning (Adendorff 1996, Marawu 1996). Code switching will henceforth be abbreviated as CS in the rest of the text. Often teachers use CS to help students understand as an avoidance strategy to teach in English. They have no other way of getting through to students because they haven't been shown the benefits of teacher modification strategies employed by the teacher I have observed in this study. The study therefore seeks to establish or investigate and describe the modification strategies the teacher uses to make his lessons comprehensible to his learners and to accommodate the needs of his L2 learners in view of the fact that he does not share the language of his learners. The motivation behind this study stems from the difficulties experienced by L2/ESL learners learning through the medium of English. These problems are described by researchers such as Macdonald (1990), Eiseman (1992), NEPI report (1992). These difficulties relate to the lack of vocabulary, low proficiency levels and comprehension skills. In view of the above, this case study research was conducted on one teacher to find out or investigate how he modifies his teaching strategies. It has been revealed in the literature studied / reviewed that teachers employ a variety of teaching strategies to adapt to the needs of their L2 learners. (Long (1983), Wong-Filhnore (1985), Chaudron (1988), Huizenga et al (1990)). The teacher in this study has also been found to employ the main strategies to modify his teaching practice. It is clear from the interviews with both the teacher and his students, that this particular teacher makes full use of a range of language and methodological strategies to help his students understand his lessons. It is hoped that the findings of this research may illuminate some valuable insights in the necessity and usefulness of teacher modification strategies for all teacher trainers so that our teaching institutions can provide a variety of methods for teacher trainees to help L2 students develop their English language skills.

The relevancy resides in the Jungian assumption that myth structures psychic experience to the benefit of the individual and ultimately, society. To this end, I have taken the hero myth of Heracles, and, by filtering it through Jung’s system promoting psychological maturation, that is what he called the individuation process, I have reconfigured it in fine art form

- Description: The benefits of informal mentoring are numerous and organisations have recognised these benefits in terms of organisational development. There has been an attempt to harvest these benefits through the introduction of formal mentoring programmes as a tool to fast track and then ultimately retain internal capability. This research on formal mentoring programmes occurred within a qualitative paradigm and data was obtained through document analysis and interviews from five mentoring pairs in one organisation and four mentoring pairs in another. The data was then presented and analysed in terms of the models proposed in the literature. The aim of this research was to evaluate formal mentoring programmes within South African organisations based on a framework provided by the literature. It was found that the literature proposed no formal evaluation model and thus, one was developed based on models of programme evaluation and formal mentoring implementation models. On the evaluation of the two formal mentoring programmes, it was found that there are some issues raised in the literature that are pertinent to both organisations but that there were also issues that were only relevant to one of the programmes. According to the research the differences in perceived success of the mentoring programme lay in the goals of the programme relating to the broader goals and culture of the organisation. It is recommended that future research investigate the impact of organisational culture on the effectiveness of formal mentoring programmes. The research also identified a need for supportive resources although this study did not assess the appropriateness and sufficiency of the resources. Organisations also need to implement effective evaluative practices in order to implement effective changes to the programme.

- Description: On the 21st September 1995, the government introduced the Motor Industry Development Programme (MIDP), in compliance with the General Agreement on Tariffs and Trade (GATT) and the World Trade Organization (WTO). Deliberate efforts by the South African government were required to promote structural changes to the domestic motor industry by opening up the economy to international competition through a programme of tariff reduction and export promotion. The integration of the South African automotive industry into global markets would have been extremely difficult, if not impossible, without the MIDP and it would thus be safe to conclude that the economic performance of the researched would have been close to impossible if it was not for the MIDP. The MIDP, as an economic policy, has been embraced by the researched company as a "vehicle" to drive corporate goals in terms of value creation for all stakeholders. The research proposition that the MIDP as an economic policy has contributed to the economic performance of the researched company is examined. In this respect, Annual and Management Accounting reports were analyzed to determine the effect the MIDP has had on the researched company over the last ten years. In addition, two semi-structured interviews were also conducted with the Strategic Finance Planning executive and the Financial Controller of the company. The results show that the MIDP has had positive spin-offs for the researched company. The same results should be valid for the other original equipment manufacturers (OEMs) in the local automotive industry that have embraced the MIDP as a vehicle to create economic value added.

- Description: ‘What is required is the ‘politics of the rhizome’ in which everyone, every community, every nation and every major region comes to terms with the uniqueness of their situation and acts accordingly – and realises that it is only by vast numbers of people, of groups and organizations acting in accordance with possibilities of their situations, that the environmental crisis will be solved.’ (Gare, 1995:161). The study investigates the implementation of Local Agenda 21’s education, awareness and training component by the Gaborone City Council Environmental Health Department (GCCEHD) to address environmental challenges facing the city of Gaborone, the capital city of Botswana. The research was conducted as a qualitative case study that made use of semi-structured interviews, focus group interviews and document analysis as instruments of data generation. Samples of respondents were selected from the Gaborone City Council (GCCEHD) employees in management positions, workers, and elected political councillors. The study is contextualised through establishing environmental issues in the Gaborone City Council, identifying strategies to address environmental issues and the review of the Waste Management Plan 2003-2009, which the department uses as a guiding document for waste management. The study establishes that the council employees are mostly concerned with issues of waste management and need commitment from all Local Government sectors of the work force. The study established the importance of education, awareness and training as a response to environmental issues facing Gaborone. The study also establishes the need for social education in terms of public education, awareness and training needed for the public to adequately respond to environmental challenges in their context. Models and relevant policy and guiding documents such as the Vision for Greater Gaborone, DPSEEA Model and Botswana Environmental Planning Principles were identified and recommended for the department to consider. The awareness and training activities should be developed and involve the community in environmental management. This should enable the council to create opportunities for income generation, at the same time changing community negative attitudes towards the environment and improving service delivery by the department.

- Description: The exponential growth of the Internet and other new technologies globally continues to re-shape the South African consumer and business landscapes. Media and entertainment group Johnnic Communications Limited has invested more than R1 billion in new technologies in the past 10 years alone. However, the company still has to realise the desired returns on this investment – a situation that is forcing management to review all its online activities. This research project sought to determine what the key success factors are for the local and international online media industry, with a view to recommending potentially viable Internet strategies that could turn around operations such as Johnnic Communications’ online offerings from being nice-to-have cost centres, into exciting and key profit-generating streams. The research found that while Internet offerings cannibalise the readership of printed newspapers in South Africa, new technologies also present media houses with the opportunity to tap into new and broader markets, and hence new revenue streams. To that extent, it concluded that continuing to invest in the Internet is an imperative for Johnnic Communications, rather than an option. In addition to recommending new digital strategies, the research also concludes that developing critical mass and having a clear online strategy are crucial factors towards the company making money out of new technologies.

- Description: A multi-input multi-output system to implement on-line process monitoring and intelligent control of complex curvature friction stir welding was proposed. An extra rotation axis was added to the existing three translation axes to perform friction stir welding of complex curvature other than straight welding line. A clamping system was designed for locating and holding the workpieces to bear the large force involved in the process between the welding tool and workpieces. Process parameters (feed rate, spindle speed, tilt angle and plunge depth), and process conditions (parent material and curvature), were used as factors for the orthogonal array experiments to collect sensor data of force, torque and tool temperature using multiple sensors and telemetry system. Using statistic analysis of the experimental data, sensitive signal features were selected to train the feed-forward neural networks, which were used for mapping the relationships between process parameters, process conditions and sensor data. A fuzzy controller with initial input/output membership functions and fuzzy rules generated on-line from the trained neural network was applied to perceive process condition changes and make adjustment of process parameters to maintain tool/workpiece contact and energy input. Input/output scaling factors of the fuzzy controller were tuned on-line to improve output response to the amount and trend of control variable deviation from the reference value. Simulation results showed that the presented neuro-fuzzy control scheme has adaptability to process conditions such as parent material and curvature changes, and that the control variables were well regulated. The presented neuro-fuzzy control scheme can be also expected to be applied in other multi-input multi-output machining processes.

Simulation results showed that the presented neuro-fuzzy control scheme has adaptability to process conditions such as parent material and curvature changes, and that the control variables were well regulated. The presented neuro-fuzzy control scheme can be also expected to be applied in other multi-input multi-output machining processes.

- Description: HIV/AIDS has emerged as the leading cause of death in South Africa, with young people being the most affected. Awareness of HIV/AIDS is quite high, yet prevalence rates have not stabilised and are still climbing. Lack of sexual behavioural change among young people is a major factor which explains why prevalence rates are still on the increase among this population. Sexual behaviour change is influenced by perceptions and attitudes, most notably perceived susceptibility. Information on the psychological factors that affect perceived susceptibility can provide an important base for the development of programmes aimed at reducing further transmission among young people. A survey, using a self-administered, anonymous questionnaire with close-ended questions to collect data, was conducted among Grade 11 learners (n = 318) in Rini, Grahamstown, South Africa. One of the constructs (namely Perceived Susceptibility) in the Health Belief Model informed the data collection. The data generated were first analysed descriptively, providing percentages for responses. Secondly cross-tabulations were calculated. The results showed that knowledge about HIV/AIDS is sufficient, young people receive accurate and non-conflictual messages about sex and HIV/AIDS, they are not discriminatory towards People Living With HIV/AIDS, they have adequate access to healthcare and their perceived susceptibility to HIV/AIDS is high. All these are factors which are favourable and conducive for positive sexual behavioural change. However, the study also found that there was little behaviour change among young people especially regarding regular condom use and decreased sexual activity.

- Description: Cultural and educational functions of public service broadcasting come at a fortuitous time, as the changing environment of broadcasting is on various agendas. At the heart of this is the question of the present and future status of public service broadcasting. Major changes have taken place in the political economy of the media and the world economy at large, technological advancement has resulted in privatization and commercialization of the media. In most societies where these changes have taken place, public service broadcasting has been threatened by the rapid rise of commercial institutions, resulting in stiff competition for audiences. This study will examine the extent to which the adoption of the Commercialization Act (No 26) of 2001 in Zimbabwe has affected Radio Zimbabwe’s role as a public broadcaster. The study is based on the hypothesis that with the adoption of the Commercialization Act, Radio Zimbabwe is no longer playing its public service role effectively. The current nature of programming at Radio Zimbabwe as the research hopes to show will highlight tremendous changes towards a commercial logic. The study uses a combination of document analysis, secondary literature and qualitative interviews.

- Description: The purpose of this study was to critically investigate challenges in the provision of low-income housing in the Nelson Mandela Bay Municipality (NMBM). In order to reach this goal, it was necessary to study the literature on the housing sector, especially as regards the impact between the external factors and the provision of low-income housing. A further supporting objective was to investigate and analyse the challenges in order to develop techniques and strategies for solving the challenges facing the NMBM in the provision of low-income housing. In order to address the reach problem and to fulfil the research objectives, an in-depth literature study was done. Empirical studies were also performed by means of face-to-face interviews and a questionnaire with the target group in the Housing Department of the NMBM. The literature and empirical study made it possible to identify underperformance and to recommend possible solutions for the challenges in the provision of low-income housing in the NMBM. These recommendations should be of value to all participants in the housing sector. From the investigation into the NMBM in the provision of low-income housing, the findings indicate that the constraints and challenges such as the housing backlog also exist in other parts of South Africa. Challenges such as availability of land in the NMBM can be considered to exist principally in the NMBM area. The new national policies and local government housing strategies should concur with the internationally accepted developmental approach. Recommendations were made with regard to sustainable development strategies, housing policies, finance and housing provision. Essential proposals were made, such as efficient financial support, and to train and improve certain unskilled staff in the NMBM. The study concludes with recommended techniques and strategies for the improvement of low-income housing in the NMBM, in order to overcome its challenges and to empower it on a sustainable basis.

- Description: This study is a contribution to the literature on South Africa's foreign policy since 2000-2004. It provides a theoretical framework within which South Africa's foreign policy should be understood. It attempts to explain the contradictions that have been apparent in South Africa's foreign policy by looking at the constraints inherent in South Africa's position as an emerging middle power. It argues that South Africa's pluralist inclinations are constrained by Africa's evolving multilateral forums and that South Africa's preference for such undermines the realization and achievement of her foreign policy principles and goals. It also argues that as a realist middle power, South Africa is constrained the ambivalence shown by the region towards her exercising leadership in the region. This is due to South Africa's history of destruction in Southern Africa in the 1980's. South Africa's quiet diplomacy towards Zimbabwe provides the focal point for the study. The study argues that it is not the case that South Africa is not concerned with human rights abuses in Zimbabwe. Instead, this concern has been expressed in ways that do not tarnish South Africa's own image in Africa. This has been done by engaging Zimbabweans through multilateral forums. This study concludes that this strategy failed to bring about resolution to the Zimbabwean crisis.

- Description: We are living in a changing world. Performance management is becoming a major challenge for organisations. The aim of this study is to review the current status of the Performance Management and Development System at the Department of the Premier and to look into the reasons why it has become a pain rather than a gain to both the organisation and its employees. This document will also look at the possible causes of the failure of the performance management system and will then propose useful guidelines to overcome obstacles to the benefit of all the affected parties. To achieve this objective a comprehensive literature study was performed to the Department of the Premier to determine the views on performance, and on performance management programmes. The study also included an investigation into the extent to which a performance management programme should be aligned with Provincial Government Western Cape (PGWC) and individual goals. Questionnaires developed from the literature study, were distributed amongst randomly selected respondents, in order to determine the extent to which a specific directorate manages performance, in line with the guidelines provided by the literature study. The information obtained from the questionnaires were compared with the guidelines provided by the literature study in order to identify shortcomings in the influence that the performance management programme has on the achievement of Department and individual goals at the selected Directorates. The objective of this study was to evaluate the influence of the current performance management system, in the Department at Provincial Government Western Cape, as a facilitation tool in aiding or assisting management in achieving individual and departmental goals. To achieve this objective a comprehensive literature study was performed to determine the views on performance, and on performance management systems. A questionnaire was designed based on the guidelines in the literature study, in order to establish the extent to which the organisation manages performance. The completed questionnaires were returned and these were processed and analysed using Microsoft Office Excel 2003, running on the Windows XP suite of computer packages. The respondent’s opinion obtained from the questionnaires were compared with the guidelines provided by the literature study in order to identify shortcomings of the influence that the performance management system has on the achievement of individual and departmental goals at the selected organization. The research results indicate that the majority of staff supports and understands the process.

- Description: In 1981 the apartheid military initiated a chemical and biological warfare (CBW) programme (code-named Project Coast). The programme, terminated in 1993, was aimed at developing novel irritating and incapacitating agents for internal and external use, covert assassination weapons for use against apartheid opponents, and defensive equipment for use by South African Defence Force (SADF) troops in Angola. The CBW programme was driven by a single individual, Dr Wouter Basson, who reported to a military management committee (the Co-ordinating Management Committee) which comprised a select group of high ranking officers. Practical and financial oversight of the programme was weak which allowed both for the abuse of programme funds and for senior military officers to deny knowledge of aspects of the programme. The biological component of Project Coast was conducted in violation of the commitments of the South African government to the Biological and Toxins Weapons Convention (BTWC). While the state’s commitment to the BTWC was one of the factors considered when initiating the programme, it was not a sufficient constraint to prevent the development of the biological weapons programme, but rather influenced its structure such that the programme could avoid national and international detection. Despite efforts to conceal the military front companies where the chemical and biological warfare (CBW) research and development was undertaken, evidence presented in this thesis shows that the United States had sufficient information about the programme to have been aware of its existence. Yet, it was only in 1993, on the eve of the democratic election in South Africa, that any attempt was made by the US administration to pressure the government to terminate the programme. This thesis considers the factors which influenced the decision to develop Project Coast; the structure and nature of the programme; the motivations of scientists to become involved in the programme and remain involved; the use of chemical and biological agents against opponents of the state, and the factors which influenced the termination of the programme on the eve of the first democratic elections in 1994. It also considers the nature and exent of international support, both tacit and overt, for the programme and argues that the failure of Western nations to call for the termination of the programme before the early 1990s was a function of political expediency and indicates a significant weakness in the ability of international agreements to constrain the development of such programmes.

- Description: This thesis explores various dilemmas in making theatre performances in the context of social disruption, trauma and death. Diverse discourses are drawn in to consider issues of body, subjectivity and spectatorship, refracted through the writer’s experiences of and discontent with making theatre. Written in a fractal-like structure, rather than a linear progression, this thesis unsettles discourses of truth, thus simultaneously intervening in debates about the epistemologies of the body and of theatre in context of the academy. Chapter 1: Methodological Anxieties Psychoanalytic theory provides a way in for investigating the dynamics of theatrical performance and its corporeal presence, by focusing on desire and its implication in the notions of loss and anxiety. The theories of the unconscious and the gaze have epistemological implications, shifting definitions of “presence” and “truth” in theatre performance and writing about theatre. This chapter tries to outline the rationale for, as well as to enact, an alternative methodology for writing, as an ethical response to loss that does not insist on consensus and truth. Chapter 2: (Refusing to) Look at Trauma This chapter examines the politics that strives to make suffering visible. Discursive binaries of public/private, dead/living, and invisible/visible underlie the politics of AIDS and sexuality. These discourses impact on the reception of Bill T. Jones's choreography, despite his use of modernist artistic processes in search of a bodily presence that aims to collapse the binary of representation (text) and its subject (being). The theory of the gaze shows this politics to be a phallocentric discourse; and narrative analysis traces the metanarrative that results in the commodification of oppositional identities, so that spectators participate in the politics as consumers. An ethical artistic response thus needs to shift its focus to the subjectivity of the spectator. Chapter 3: The Screen and the Viewer’s Blindness By appealing to a transcendent reality, and by constituting spectators as a participative community, ritual theatre claims to enact change. The “truth” of ritual rests not on rational knowledge, but on the performer’s competence to produce a shamanic presence, which director Brett Bailey embraces in his early work. Ritual presence operates by identification and belonging to a father/god as the source of meaning; but it represses the loss of this originary wholeness. Spectators of ritual theatre are drawn into an enactment of communion/community, the centre of which is, however, loss/emptiness. The claim of enacting change becomes problematic for its absence of truth. Bailey attempts to perform a hybrid, postcolonial aesthetics; but the problem rests in the larger context of performing the notion of “South Africa”, a communal identity hardened around the metanarrative of suffering, abjecting those that do not belong to the land of the father/god – foreigners that unsettle the meaning of South African identity. Conclusion: Bodies of Discontent The South African stage is circumscribed by political and economic discourses; the problematization of national identity is also a problematization of image-identification in the theatre. In search for a way to unsettle these interrogative discourses, two moments of performing foreignness are examined, one fictional, one theatrical. These moments enact a parallel to the feminine hysteric, who disturbs the phallocentric truth of the psychoanalyst through body performance. These moments of disturbing spectatorship are reflected in the works of performance artist Marina Abramovic. Her explorations into passive-aggression, shamanism and finally theatricality and the morality of spectatorship allow for an overview of the issues raised in this thesis regarding body, viewing, and subjecthood. Sensitivity to the body and its discontent on the part of the viewer becomes crucial to ethical performance.

Spectators of ritual theatre are drawn into an enactment of communion/community, the centre of which is, however, loss/emptiness. The claim of enacting change becomes problematic for its absence of truth. Bailey attempts to perform a hybrid, postcolonial aesthetics; but the problem rests in the larger context of performing the notion of “South Africa”, a communal identity hardened around the metanarrative of suffering, abjecting those that do not belong to the land of the father/god – foreigners that unsettle the meaning of South African identity. Conclusion: Bodies of Discontent The South African stage is circumscribed by political and economic discourses; the problematization of national identity is also a problematization of image-identification in the theatre. In search for a way to unsettle these interrogative discourses, two moments of performing foreignness are examined, one fictional, one theatrical. These moments enact a parallel to the feminine hysteric, who disturbs the phallocentric truth of the psychoanalyst through body performance. These moments of disturbing spectatorship are reflected in the works of performance artist Marina Abramovic. Her explorations into passive-aggression, shamanism and finally theatricality and the morality of spectatorship allow for an overview of the issues raised in this thesis regarding body, viewing, and subjecthood. Sensitivity to the body and its discontent on the part of the viewer becomes crucial to ethical performance.

- Description: Previously, our workplaces were characterised by serious hardships emanating from labour laws which did not always cater for all areas of the employment relationship. South African female employees were without a clear legitimate remedial right precluding any severe violation and infringement to their fundamental rights resulting from their pregnancy; a task they did not opt for in the first place, but was instead, naturally imposed on them as a result of their gender category. Undoubtedly, many female employees were victims of unfair discrimination. The legislature therefore saw it fit to democratise the workplace by making rapid statutory interventions. As a result, a number of significant changes in various spheres of our labour laws were brought in. Amongst the greatly notable valuable changes was the introduction of the Employment Equity Act 55 of 1998. This piece of legislation has generally reformed our industrial society by bringing in the elimination of unfair discrimination and thereby enhancing the principle of equity in the workplace. The act has further touched a place within hearts of female employees for fear of discrimination as a result of their pregnancy status or any reasons related to their pregnancy. The act further codified Industrial Court decisions that were already established under the discrimination law jurisprudence from the Labour Relations Act 28 of 1956. The application of the provisions of the Act has made the employment relationship no longer to be a comfort zone for employers. These general changes to the law also impact on the dismissal law regime. The purpose of this treatise is to give an overview of the applicable legislation and contributions made by the Labour Courts in developing pregnancy dismissal and discrimination law. The Labour Courts have handed down few judgements that have helped in clarifying the provisions of both the current Labour Relations Act and the Employment Equity Act around the topic. One should hasten to say that this has never been a smooth process by the courts. It is further shown in this treatise that some of the court decisions were not well accepted in the light of other important considerations, such as the equality provisions of the Constitution. For the purpose of effectively dealing with this topic, this treatise contains a discussion of the historical context of discrimination law in the form of common-law position, and the discrimination law before the Bill of Rights and the Constitution. It then endeavours to identify the legislative provision of the Act when it comes to discrimination law provisions. At the same time the important court decisions that were made are identified and examined.

- Description: Information and Communication Technologies (ICTs) are becoming more pervasive in South African schools and are increasingly considered valuable tools in education, promoting the development of higher cognitive processes and allowing teachers and learners access to a plethora of information. This study investigates models of Internet connectivity for secondary schools in the Grahamstown Circuit. The various networking technologies currently available to South African schools, or likely to become available to South African schools in the future, are described along with the telecommunications legislation which governs their use in South Africa. Furthermore, current ICT in education projects taking place in South Africa are described together with current ICT in education policy in South Africa. This information forms the backdrop of a detailed schools survey that was conducted at all the 13 secondary schools in the Grahamstown Circuit and enriched with experimental work in the provision of metropolitan network links to selected schools, mostly via Wi-Fi. The result of the investigation is the proposal of a Grahamstown Circuit Metropolitan Education Network.

- Description: Grid computing technologies facilitate complex scientific collaborations between globally dispersed parties, which make use of heterogeneous technologies and computing systems. However, in recent years the commercial sector has developed a growing interest in Grid technologies. Prominent Grid researchers have predicted Grids will grow into the commercial mainstream, even though its origins were in scientific research. This is much the same way as the Internet started as a vehicle for research collaboration between universities and government institutions, and grew into a technology with large commercial applications. Grids facilitate complex trust relationships between globally dispersed business partners, research groups, and non-profit organizations. Almost any dispersed “virtual organization” willing to share computing resources can make use of Grid technologies. Grid computing facilitates the networking of shared services; the inter-connection of a potentially unlimited number of computing resources within a “Grid” is possible. Grid technologies leverage a range of open standards and technologies to provide interoperability between heterogeneous computing systems. Newer Grids build on key capabilities of Web-Service technologies to provide easy and dynamic publishing and discovery of Grid resources. Due to the inter-organisational nature of Grid systems, there is a need to provide adequate security to Grid users and to Grid resources. This research proposes a framework, using a specific brokered pattern, which addresses several common Grid security challenges, which include: Providing secure and consistent cross-site Authentication and Authorization; Single-sign on capabilities to Grid users; Abstract iii; Underlying platform and runtime security, and; Grid network communications and messaging security. These Grid security challenges can be viewed as comprising two (proposed) logical layers of a Grid. These layers are: a Common Grid Layer (higher level Grid interactions), and a Local Resource Layer (Lower level technology security concerns). This research is concerned with providing a generic and holistic security framework to secure both layers. This research makes extensive use of STRIDE - an acronym for Microsoft approach to addressing security threats - as part of a holistic Grid security framework. STRIDE and key Grid related standards, such as Open Grid Service Architecture (OGSA), Web-Service Resource Framework (WS-RF), and the Globus Toolkit are used to formulate the proposed framework.

Assessing the potential of submaximal extended duration exercise as an adjunct treatment for sub-acute schizophrenic in-patients: a pilot study

- Description: Research into the therapeutic potential of aerobic exercise has proven fruitful over the past few years; however, no true experimental research undertakings have investigated the psychological benefits of aerobic exercise with schizophrenic semi-acute in-patients. The main objective of this thesis was to seek out evidence for the possibility that aerobic (submaximal long duration) exercise could be considered an adjunct treatment for hospitalised schizophrenic in-patients. In order to accomplish this objective the effects of a 45-minute walking programme, completed three days a week, for five weeks, was investigated. Various areas of mental health were explored in search of evidence of the therapeutic potential of aerobic exercise. These areas included, amongst other things: transfer and discharge rates, improvements in mood levels - Beck Depression Inventory-II (BDI-II; Beck, Steer, and Brown, 1996) Xhosa version; decreasing of anxiety levels (Beck Anxiety Inventory (BAI; Beck and Steer, 1993), Xhosa version); improved Global Assessment of Functioning (GAF; DSM-IV), Scale Scores; and decreases in the number of symptoms patients exhibited. 22 schizophrenic inpatients were randomly selected for this study and randomly assigned to either an aerobic (long duration submaximal) treatment group or (primarily anaerobic) control group. Results revealed that statistical significance could not be found in any of the treatment group's t-test results; despite the treatment group generally bordering on significance more so than the control group. Out of the five variables studied (Positive Symptoms, Negative Symptoms, BAI, BDI-II, and GAF Scale) three variables (Negative Symptoms, BDI-II, and GAF Scale) in the treatment group bordered more on significance than did the control group. Thus three (60 %) out of the five areas studied revealed that the treatment group had more significant results. This suggests an overall impression that the treatment group responded slightly better. The Researcher recommended that aerobic exercise therapy be considered a treatment protocol in psychiatric institutions and offered further suggestions pertaining to the effective implementation of these programmes. Included in these recommendations were motivational strategies and warnings about the possible negative effects of exercise therapy. A supplemental goal of this thesis was to explore all of the previously offered theoretical psychological mechanisms of positive mental change; and to seek out evidence, for or against these forces. Participants were given pre- and post- treatment quantitative interviews; as well as, qualitative posttreatment interviews where their phenomenological responses were analysed to seek out evidence of these mechanisms. Evidence of various causative factors was found and a new theoretical mechanism was proposed in this thesis.
