- Description: The study was triggered by a discussion with one of Transwerk’s executive management during an MBA tea break. The discussion was centred on the lack of IT Governance Structure in some organisations that are centrally managed due to geographical location and spreading of branches countrywide. The purpose of this study was to analyse the information and communication technology initiatives that can be implemented at Transwerk by the ICT department to ensure significant value from their information and communication technology investments. This was undertaken by means of a literature and an empirical study. The elements of the information and communication technology initiatives were discussed and the study then analysed the responses in an attempt to determine the initiatives that are currently implemented at Transwerk’s ICT department. The literature study indicated that is it critical for any organisation that needs to be successful should have an integrated ICT Governance Structure. The empirical study found out that the current situation at Transwerk’s ICT department requires attention because their IT Governance Structure does not involve major stakeholders from other business units. Recommendations were made as a result of analysing the literature study and empirical study to ensure the implementation of key initiatives that can add value to the organization.

- Description: This research appraises the impact of the Fast Track Land Reform Programme at three resettled communities in Kadoma District, Zimbabwe. In particular it assesses the livelihood practices of land recipients and their effects on the natural environment. Two of the communities, Lanteglos and CC Molina were resettled under the A1 villagised and self-contained settlement scheme and are found in the Natural Farming Region III. Pamene, the third community, was resettled under the A2 small-scale commercial settlement scheme and is found in the Natural Farming Region IIb. Multiple research methods including household surveys, interviews, observations, reviews of literature and map construction through the use of Geographic Information Systems, allowed for the collection of empirical, descriptive, and spatial data to provide for the appraisal. The land use practices included dry land crop production, livestock rearing, vegetable gardening and exploitation of the natural environment for a variety of purposes. Farming was mostly subsistence with the use of traditional equipment by all three communities. Tenure was perceived to be insecure by beneficiaries and although a variety of papers to show ownership were held, none provided for leasing or freehold tenure. Despite acquiring natural capital from the resettlement process, the findings of this research show low levels of financial, physical and social capital amongst beneficiaries. Moreover climatic variability, the declining macro-economic and unstable political environment and little support from government have adversely affected the livelihoods of beneficiaries. The implication of all this has been a reduction in livelihoods that are based solely on agricultural production, leading to off-farm practices primarily exploiting the natural environment. The long term effect would be increased degradation of the environment, leading to reduced arable and grazing land, and thereby hindering sustainable livelihoods from farming. Recommendations are proposed based on this research’s findings being typical in Zimbabwe. Central to this is the need for government to revise its present land policy and, provide for a comprehensive and holistic land policy that should be based on the vision of how agriculture should evolve in Zimbabwe

- Description: The principal objective of this thesis was to gain an understanding of the movement patterns of spotted grunter Pomadasys commersonnii, an estuarine-dependent fishery species, in the turbid, freshwater dominated Great Fish Estuary. Both manual and automated telemetry methods were used to monitor the movements of spotted grunter during two separate studies conducted in summer and spring 2003 and 2004. Acoustic transmitters were surgically implanted into twenty spotted grunter with lengths between 263 and 387 mm TL in the first study and twenty spotted grunter ranging between 362 and 698 mm TL in the second study. The specific objectives were to gain an understanding of (i) the time spent in the estuarine environment (ii) the space use and home range size, and (iii) the abiotic factors governing the movement patterns of spotted grunter in the estuary. The nursery function of estuarine environments was highlighted in this study as adolescent spotted grunter spent a significantly larger proportion of their time in the estuary than adult fish (p < 0.0001; R² = 0.62). The increased frequency of sea trips, with the onset of sexual maturity, provided testimony of the end of the estuarinedependent phase of their life-cycle. Although considered to be predominantly marine, the adult spotted grunter in the Great Fish Estuary utilised the estuary for considerable periods. Adults are thought to frequent estuaries to forage, seek shelter and to possibly rid themselves of parasites. During this study, the number of sea trips made by tagged fish ranged from 0 to 53, and the duration ranged from 6 hours to 28 days. The tidal phase and time of day had a significant effect (p < 0.05) on the sea trips undertaken by fish. Most tagged spotted grunter left the estuary during the night (84%) on the outgoing tide, and most returned in the evening (77%) during the incoming tide. Sea temperature (p < 0.0001; R² = 0.34), barometric pressure (p = 0.004; R² = 0.19) and wind (p = 0.01) had a significant effect on the number of spotted grunter recorded in the estuary. Spotted grunter were more prone to return to the estuary after high barometric pressure, when low sea temperatures (upwelling events) prevailed. There was a significant positive relationship between home range size and fish length (p = 0.004; R² = 0.20). Small spotted grunter (< 450 mm TL) appeared to be highly resident, with a small home range (mean size = 129 167 m²), that was generally confined to a single core area. Larger individuals (> 450 mm TL) occupied larger home ranges (mean size = 218 435 m²) with numerous core areas. The home ranges of small and large spotted grunter overlapped considerably yielding evidence of two high use areas, situated 1.2 km and 7 km from the mouth of the Great Fish Estuary. Tagged spotted grunter were located in a wide range of salinity, turbidity and temperature, but were found to avoid temperatures below 16 ºC. The daily change in environmental variables (salinity, temperature and turbidity) had a significant effect on the change in fish position in the estuary (p < 0.0001; R² = 0.38). The distribution of tagged spotted grunter, particularly the larger individuals, in the Great Fish Estuary was influenced by the tidal phase (p < 0.05); they moved upriver on the incoming tide and downriver on the outgoing tide. This study provides an understanding of the movement patterns of spotted grunter in the estuary and between the estuarine and marine environments. Consequently, it provides information that will assist in the design of a management plan to promote sustainability of this important fishery species. The techniques used and developed in this study also have direct application for further studies on other important estuarinedependent fishery species.

- Description: The overall objective of this study was to delve into the intricacies of the therapeutic process and the therapeutic relationship from an attachment perspective. A single retrospective child case study was conducted, which entailed the construction of a narrative synopsis of the process. The hermeneutic approach of a Reading Guide Method was applied, and through a repeated re-reading of the narrative, pertinent themes emerged that shed light on therapy as a process in motion. Specifically, the motion of the therapeutic process manifested through a scrutiny of the therapeutic relationship in view of the participant’s attachment style. The results of this study revealed the capacity of the participant to move away from an avoidant and somewhat ambivalent organisation of defences by virtue of establishing a secure base and exercising her faculty for emotional and self-expression. Accordingly, it can be established that in view of psychotherapy from an attachment perspective, the seemingly imperceptible vicissitudes of change are indeed appreciable.

- Description: Despite the acknowledgement of the developmental nature of careers, little attention has been focused on identifying shaping influences during childhood. This noticeable deficiency in the literature marked the start of the current longitudinal study which was designed to provide information on the career development of nine to twelve-year old South African children. In South Africa research focusing on preadolescent career development is limited with existing research indicating the need to further explore how children’s career choice process initially develops. The study aimed to explore and describe the changes that occur, if any, over a four-year period in terms of occupational interest typology, occupational status levels, occupational gender stereotypes and occupational gender traditionality. Both developmental and career developmental theories were used to provide a context for exploring this process of preadolescent career development. It was decided that quantitative research methods would provide the necessary structure needed to conduct the research. Although semistructured interviews and biographical questionnaires were used to record the verbal data, the data obtained was transposed into nominal data for analysis. Participants responded to questions within a semi-structured interview that focused on four broad areas of questioning. These questions explored participants’ occupational aspirations, how many occupations they knew about, how much they knew about the identified occupation, and the extent to which they held gender-role stereotypes about certain occupations. After the data was iv Key words: career development, children, longitudinal research, occupational aspirations captured it was coded according to Holland's (1985) classification system of occupational interest types. The occupational aspirations expressed by the participants were also coded in terms of their status levels. The coded data was then further analysed using descriptive statistics in the form of frequency counts and percentages. Results from the study support both child and career development theory which view childhood as a time of rapid growth with critical development in various competency areas (including occupational aspirations and perceptions). Although the current study found that most children aspired to Social occupations, the popularity of this typology decreased with increasing age as more children aspired to Investigative, Artistic, and to a lesser extent, Realistic typologies at age twelve. Furthermore, it appears that children, like adults, are aware of status differentials among occupations and that this awareness subsequently influences occupational aspirations. Lastly, the findings broadly provide support for both national and international research in that it was established that an increase in age reflects a decrease in gender-stereotypical perceptions of occupations. The present study gained valuable insight into how the process of career development occurs in preadolescent children. It is clear that there exists a need for the implementation of credible and sustainable career education programs in schools across South Africa in order to encourage and facilitate career exploration during the developmental stage of childhood.

- Description: The extensive amount of research conducted in the field of family violence internationally indicates that child abuse has a detrimental effect on both the physical and emotional development of children as well as having a profound effect on an individual’s psychological development and functioning in adult life. The aim of this research study was to describe the therapeutic process that unfolded with a seven year old allegedly abused female client within the framework of non-directive play therapy. The case was further contextualised utilising Erik Erikson’s theory of psychosocial development. This study served to broaden the body of psychotherapeutic knowledge by means of meaningful qualitative enquiry. The client was referred for therapy because of severe emotional and behavioural problems following the alleged sexual abuse. The client was seen over a period of eight months and this included 11 sessions of non-directive play therapy, three parent interviews and psychometric assessments conducted by a colleague. The case study method was utilised in this study. To achieve the aim of the research, the methodology of choice was the descriptive dialogic case study. A purposive sampling technique was used in the selection of the research subject for this study. The data collection and analysis were conducted according to Yin’s (1994) analytical generalisation, which consists of two main strategies: (a) using a theoretical framework as a guide to determine what data is relevant; and (b) developing a matrix as a descriptive framework for organising and integrating the data. Furthermore, the process of data analysis was aided by the use of guidelines proposed by Irving Alexander (1988) with Axline’s non-directive play therapy and Erikson’s theory of psychosocial development as the theoretical frameworks. The findings of this study suggest that plotting the play therapy sessions according to the framework of the four stages of play therapy was a particularly useful tool to monitor Michelle’s progression through the therapeutic process. This can be seen as a valuable application of a tool which can be used within the non-directive play therapy approach. Contextualising Michelle’s development according to the stages of Erikson’s theory of psychosocial development was also found to be a valuable endeavour. According to her chronological age, Michelle should have been in the fourth stage of industry versus inferiority, but in reality Michelle was still struggling to strike a healthy balance between the terms of conflict of trust versus mistrust issues of the first stage. From a therapeutic point, this was an important exercise as it helped to inform the therapist and consequently, the therapeutic process. This research undertaking can be recognised as a positive demonstration of the value of non-directive play therapy (Virginia Axline) and Erik Erikson’s theory of psychosocial development in the therapeutic process. In addition, this study has served to facilitate a more holistic understanding of the case study approach to research. Recommendations regarding future research undertakings that utilise the case study approach and methodology have been made. Key concepts: child abuse; family violence; non-directive play therapy; Erik Erikson’s theory of psychosocial development; analytical generalisation; case study research.

- Description: 1992 marked a turning point in Nigeria’s broadcasting history as the country formally deregulated her broadcast space. However, it was not until March 2002 that the first commercial radio station was established in Rivers State, a broadcast environment hitherto monopolised by Radio Rivers. The coming of the first independent radio station in Rivers State in March 2002 was followed by the establishment of two other stations in October 2003 and November 2003 respectively. As important as these events in broadcasting in Rivers State are, however, media scholars have argued that in most societies where such change has taken place, public service broadcasters have tampered with their values of being an open space where individuals and groups can come together to be educated, informed, and entertained. This study investigates the extent to which the proliferation of commercial broadcasting outlets has affected Radio Rivers’ public service programming and scheduling. Using a combination of qualitative and quantitative research methods, through in-depth interviews and analysis of the mandate and programme schedules, the study established that while Radio Rivers still maintains some public service values, its current programming policy is driven by the need to compete with the commercial broadcasters. This is evidenced in the decrease in the programme space allocated to current affairs and educational programmes on the schedule, (the genre of public service broadcasting), and the increase in attention to advertisements and entertainment programmes, (the genre of commercial broadcasting). The study also confirms the adverse effects of dwindling financial resources as forcing public service radios to compromise on their public service values, as majority of programmes on Radio Rivers current programme schedules are now geared towards attracting advertisers rather than serving the public good and interests. However, the study proved that it is not in all cases that the entry of commercial broadcasters into Rivers State broadcast space has undermined Radio Rivers public service values. Indeed, in leading to the expansion of interactive, news, and the diversification of entertainment programmes spaces on Radio Rivers’ programming schedules, the proliferation of commercial broadcasters has yielded some positive effects on Radio Rivers public service values and contribution to the public sphere. The study further highlights the need for some policy reforms at Radio Rivers, such as the introduction of licence fees, increased government funding and loosening government’s current control over the station. In addition, there is the need for the edict establishing the station to be amended to reflect the current trends in broadcasting in Rivers State, and above all to reposition Radio Rivers to sustain public good and public interests in its programming.

- Description: This thesis examines the narrative situation within Herman Charles Bosman’s “Oom Schalk Lourens” series of stories, focussing on the nature of the relationship between author and narrator. In particular, it seeks to trace the source of the multiple ironies at work in the texts. It has been customary for critics in the past to claim that the irony within the stories stems from Bosman, operating authorially ‘above’ Oom Schalk. In terms of this theory, Oom Schalk is read as being largely unaware of the inconsistencies and contradictions within his narrative. It is the claim of this thesis, however, that Oom Schalk is the self-aware creator of the texts’ ironies much of the time. Chapter 1 commences with an attempt at defining irony, and provides a brief overview of the history of its deployment within South African literature before discussing the literary genre which Bosman was to exploit as his ironic vehicle: the “oral-style” short story. Chapter 2 examines Wayne C. Booth’s notions of “stable” and “unstable” irony: the irony of the Oom Schalk stories has, in the past, been classified as belonging to the former category, but this thesis attempts to show that its inconsistent deployment within the stories consigns it more accurately to the latter. Chapter 3 offers an assessment of the extrinsic contexts relevant to the analysis: the context of the stories’ publication, and the likely composition of Bosman’s reading public. Chapter 4 begins to examine the distance between implied author and implied narrator in the stories. Chapters 5, 6 and 7 subject stories dealing with the themes of art, race and land to detailed analysis in order to examine the shifting – and progressively, though unevenly, diminishing – distance between Bosman and Oom Schalk. The thesis concludes that the degree to which the ironic distance between author and narrator fluctuates within, and between, the stories, results in a narrative situation which must be classified as fundamentally unstable.

- 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: To enable a business to grow and to uplift the economic and social development of its employees, it is vital that skills are provided to individuals. Businesses today strive to retain employees, as their skills learnt, prove to be a valuable asset that takes years to replace. For this reason, all means available are utilised to retain employees in the workplace. The term coaching is a relatively newcomer to the world of business and is seen to take a holistic view of the individual and focuses on work, corporate values, personal needs and career development. The main objective of this study was to identify coaching strategies that can be implemented by organisations in order to ensure the retention and development of employees. Businesses have to rely on employees to help them achieve financial growth, outperform their competitors, produce innovative products and to achieve long-term goals. These tasks would be impossible to achieve if the interests of employees were neglected. It was established from the literature survey that the coaching style of leadership involved more than simply training managers in coaching skills. A whole new coaching culture needed to be implemented in businesses in order to bring about change. Coachees rely on effective coachers to provide guidance and to demonstrate the skills needed. Based on various models in the literature survey a coaching model was formulated. The empirical survey was conducted at five selected companies in the Buffalo City Municipal area. A theoretical model for organisational coaching was developed and tested by means of a questionnaire. It emerged that employees at lower levels had not been involved in any form of coaching.

- Description: This dissertation mainly deals with some biochemical aspects regarding the efficacy of novel platinum anticancer compounds, as part of a broader study in which both chemistry and biochemistry are involved. Various novel diamine and N-S donor chelate compounds of platinum II and IV have been developed in which factors such as stereochemistry, ligand exchange rate and biocompatibility were considered as additional parameters. In the first order testing, each of these compounds was tested with reference to their “killing” potential by comparing their rate of killing, over a period of 48 hours with those of cisplatin and oxaliplatin. Some 80 compounds were tested in this way. Although only a few could be regarded as equal to or even better than cisplatin and oxaliplatin, the testing of these compounds on cancer cells provided useful knowledge for the further development of novel compounds. Four of the better compounds, namely Y9, Y14, Y16 and Lt16.2 were selected for further studies to obtain more detailed knowledge of their anticancer action, including some flow cytometric studies. In addition to the above, cisplatin resistant cells were produced for each of the three different cell lines tested, namely, HeLa, HT29 and MCF7 cancer cell lines, by intermittent and incremental exposure to cisplatin (all the cell lines tested became resistant to cisplatin). Each of the selected compounds were exposed to the cells in the same manner, in order to attempt the induction of resistance against these compounds in the three cell lines tested (i.e. whether these cells will become resistant to the various compounds). Each of these selected platinum containing compounds were subsequently tested against the “cisplatin resistant” cell lines in order to determine their efficacy against such cells. One such compound could be singled out, since cervical cancer cells (HeLa cells) do not become resistant to it. This behaviour is similar to that of oxaliplatin against cervical cancer and colon cancer (HT29) cells (oxaliplatin is the number one treatment for colon cancer at present). This compound also proved to be more active against cisplatin resistant cell lines. It was found that all the compounds induced apoptosis in the cell lines tested as well as inhibit the DNA cycle at one or more phase. Finally, an effort was made to evaluate the different compounds by comparing them with respect to their properties relating to anticancer action.

The cost of free instant messaging: an attack modelling perspective

- Description: Instant Messaging (IM) has grown tremendously over the last few years. Even though IM was originally developed as a social chat system, it has found a place in many companies, where it is being used as an essential business tool. However, many businesses rely on free IM and have not implemented a secure corporate IM solution. Most free IM clients were never intended for use in the workplace and, therefore, lack strong security features and administrative control. Consequently, free IM clients can provide attackers with an entry point for malicious code in an organization’s network that can ultimately lead to a company’s information assets being compromised. Therefore, even though free IM allows for better collaboration in the workplace, it comes at a cost, as the title of this dissertation suggests. This dissertation sets out to answer the question of how free IM can facilitate an attack on a company’s information assets. To answer the research question, the dissertation defines an IM attack model that models the ways in which an information system can be attacked when free IM is used within an organization. The IM attack model was created by categorising IM threats using the STRIDE threat classification scheme. The attacks that realize the categorised threats were then modelled using attack trees as the chosen attack modelling tool. Attack trees were chosen because of their ability to model the sequence of attacker actions during an attack. The author defined an enhanced graphical notation that was adopted for the attack trees used to create the IM attack model. The enhanced attack tree notation extends traditional attack trees to allow nodes in the trees to be of different classes and, therefore, allows attack trees to convey more information. During the process of defining the IM attack model, a number of experiments were conducted where IM vulnerabilities were exploited. Thereafter, a case study was constructed to document a simulated attack on an information system that involves the exploitation of IM vulnerabilities. The case study demonstrates how an attacker’s attack path relates to the IM attack model in a practical scenario. The IM attack model provides insight into how IM can facilitate an attack on a company’s information assets. The creation of the attack model for free IM lead to several realizations. The IM attack model revealed that even though the use of free IM clients may seem harmless, such IM clients can facilitate an attack on a company’s information assets. Furthermore, certain IM vulnerabilities may not pose a great risk by themselves, but when combined with the exploitation of other vulnerabilities, a much greater threat can be realized. These realizations hold true to what French playwright Jean Anouilh once said: “What you get free costs too much”.

- Description: The underlying objective of the research is to assess the nature of the supplier training at Volkswagen of South Africa (VWSA). To achieve this objective, a theoretical study was conducted to establish what literature reveals to be the most important theory of supply chain management as well as supplier development geared towards lean manufacturing. The information obtained in the literature study was analysed to solve the main problem namely, an assessment of the nature of the supplier training at Volkswagen of South Africa (VWSA). The research was divided into two questionnaires: The first questionnaire is targeted at the suppliers. This questionnaire has two sections namely section A, the biographical data and section B attempts to determine the quality systems and manufacturing requirements. It further attempts to gauge training support and needs as compared to other OEM’s. The second questionnaire is targeted at the Supplier Development Manager. The aim of this questionnaire is to establish what the current training offerings are, the source of what VWSA teachers and the awareness of the Toyota Training College.

- Description: This case study investigates sense of place of youth amidst a background of change in postapartheid South Africa. As used in this study, sense of place refers to the attachments made to both physical and social places, and the social and cultural interactions and meanings associated with such places. The research was conducted with a group of 13 young adults at Mary Waters Senior Secondary School in Grahamstown. The literature suggests that the changes that occur in the lives of the participants at school-leaving age such as new opportunities to identify with global aspirations, tend to influence their sense of place in local contexts. Social change that occurs due to globalising forces such as access to new technologies and improved personal mobility, also influences sense of place in this context. Another integral factor is the structural influence of changing cultural and educational norms. These notions form part of the backdrop of this study. The research project was developed in response to calls for learning approaches that are situated more in local contexts and which include the youth as intrinsic participants informing environmental education approaches. This research draws attention to the significance of finding sustainable ways that enhance opportunities for agency on the part of the youth in future local and global environmental care-taking. The study took place over a period of 15 months in which time the participants undertook place-based activities in their communities around self-identified environmental concerns. The study was intentionally generative in approach as this allowed the voices of the participants and their environmental perspectives to be considered in developing methods and activities that were suitable to their particular contexts and interests. The study highlights the relevance of particular social contexts, through the perspectives of people and in this case learners, as key to environmental education enquiries. The combination of approaches that consider: a) knowledge about social context, b) the educational intervention (place-based activities) and, c) the situated social capital of the participants, all form the basis of meaningful pedagogical engagements and serve to address my research question: How is learners' sense of place developed and articulated through place-based activities, and what are the implications for environmental education amidst a contemporary landscape of change in South Africa?

- Description: Currently in South Africa when an individual is injured due to the acts of another they may claim damages for the losses which they may incur. These can be claimed from a variety of institutions, such as the Road Accident Fund, Workmen's compensation or an individual's private insurance. In all the afore-mentioned cases the calculation of damages are along the same lines, whereby the damages are quantified first, and thereafter reduced to reflect future possibilities that may occur. Traditionally future losses are reduced to reflect the possibility that the claimant may die at an age prior to the loss being incurred. To account for this risk awards for future losses are reduced using standard South African mortality tables. The set of tables currently being used were calculated from the 1985 South African census, and as such encapsulate the mortality of the population at that period. When the tables were calculated no reliable statistics were available for the Black population the result is that the tables currently being used do not contain a sample of the majority of the population. The thesis first examines, in detail, the calculation methods used to arrive at the value for damages to be awarded using the current set of life tables. Thereafter an analysis is conducted looking at differences between racial groups in the country and geographic locations, in order to uncover the mortality differences between groups to confirm or disprove the proposition that the exclusion of the Black population results in lower levels of mortality being reflected in the South African 1984-1986 life tables. This is accompanied by a review of mortality trenps in South African since 1986. Following from the findings of the expected increase in mortality since 1986, alternative life tables shall be used to show what impact these would have on the calculation of damages. Due to the fact that none of the alternatives return satisfactory results, structured settlements shall be reviewed to illustrate how the shortcomings of the lump sum approach can be circumvented, and altogether avoid the problems of out dated life tables being used as a basis for damage calculations. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The aim of this research project was to evaluate the available theoretical information on Corporate Social Responsibility and with this knowledge to then also evaluate three companieś initiatives based on this information. Gone are the days when an organisation could do business for the sole purpose of making a profit. If the organisation does not take the environment into account in doing business, or if the community where this organisation is situated or does business, feel “abused” or that their needs are not being addressed, the organisation will not survive and its future sustainability can not be assured or guaranteed. This has been proven internationally, but how does South African organisations fare when it comes to corporate social responsibility, and more specifically, what social responsible initiatives are taken? The research also attempted to determine how “industry specific” the three companies'́ initiatives are and whether any changes in initiative-directions should be considered. The Social Responsibility Initiatives of Woolworths, ENGEN and SABMiller (South Africa) were evaluated and certain shortcomings were identified and presented to the various companies. These companies deliver excellent products and services to their client base, but it was felt that should adherence be given to the recommendations that were made, the mentioned companies could in future improve their turnover, market position and increase their client support base. Finally, it could also assist in increasing brand loyalty amongst their customers.

- Description: Diabetes Mellitus (DM) is on the increase globally, with further increases expected in developing countries, such as South Africa. World Health Organization (Medical Chronicle, 2006:14) estimations indicate that the number of DM sufferers will double over the next 30 years. This increasing number of diabetics is expected to have enormous economical implications. One of the consequences of the increase in DM sufferers is the increase in deaths due to diabetes related complications. In 2000, 3.2 million people died of DM and diabetes related complications compared with 3 million who died from HIV/AIDS related illnesses (William & Pickup, 2004:64). Health services are financially burdened by DM complications that result in heavy demands in both direct costs of hospitalization and medication as well as indirect costs such as manpower of staff involved in the care of the patient (Leuner, 2000:410). Diabetic ketoacidosis (DKA) is a prominent life-threatening complication of type 1 diabetes mellitus and, if not treated medically, it can lead to coma and death. DKA accounts for 14 per cent of all diabetic related hospital admissions and has a mortality rate of 5 to 10 per cent (Pickup & Williams, 2003:1). Rapid identification of DKA is necessary to improve patient care. George- Gray and Chernecky (2002:96) suggest patient outcomes are affected by the nurse’s ability to recognize the clinical features of DKA. It is important, therefore, for the nurses to understand the signs and symptoms and treatment of this diabetes related complication. National health policies and treatment guidelines should be aimed at addressing DKA treatment through setting guidelines for diabetic care (Peters, 2004:22). The main goal of this study was to determine registered nurses’ knowledge of DKA and to develop guidelines to assist registered nurses in providing adequate and effective health care to prevent DKA reoccurrence. The research study is based pm Bergam’s model on quality of care and accountability. Bergman claims that several preconditions must be filled in order to be accountable, including: • Accountability • Responsibility • Authority • Ability (Bergman (1982:8) emphasizes that ability reflects the registered nurses’ accountability, which is composed of values, knowledge and skills.) The study was divided into two phases. Phase one determined registered nurses’ knowledge related to the management of DKA. Phase two of the study included the developing guidelines to assist registered nurses in providing adequate and effective health care to patients with DKA. The design of the study is quantitative, explorative, descriptive and contextual; a survey was performed using a questionnaire based on a literature study. Ethical principals were maintained throughout the study. Permission to the study was sought from the Local Health Authorities and the heads of department where the research was undertaken. Findings of the research were analysed and discussed in the research. The knowledge of the majority of the respondents was found to be average. Out of the thirty- two respondents 52.8 percent possessed adequate knowledge the management of DKA and 63.4 percent possessed adequate knowledge on the management of DM. Two recommendations to assist registered nurses in the implementation of guidelines of the recommendations were also provided.

- 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: Prior research (Shuttleworth-Edwards et al., 2004) presented preliminary normative data for the Wechsler Adult Intelligence Scale – III (WAIS-III) for Southern Africa, stratified according to gender (female vs. male), language (black African vs. white English), level of education (matric/12+ years of education vs. Graduate/15+ years of education) and quality of education (disadvantaged – Department of Education and Training vs. advantaged - Private/Model C). IQ scores for black African language and white English Southern Africans were comparable with the United States of America (USA) standardization when level and quality of education were equitable. (‘White English’ is the term used to denote those of European descent whose first language is English). A limitation of the research was the lack of control for language for most of the black groups and particularly in the Private/Model C Graduate group, where sixty percent of the participants originated from Zimbabwe. These represented a particularly elite group whose education was equitable to that of the white participants throughout their education (i.e. at primary, secondary and tertiary level). In order to rectify the lack of homogeneity of language, all non- Xhosa first language participants were excluded from the black sample and sixteen additional Xhosa first language participants were tested on the WAIS-III. Data analyses found no significant differences between the original and new groups, except in the comparison between Mixed African language Private/Model C Graduates and the Xhosa first language Private/Model C Graduate/15+ years of education, where there was a lowering of WAIS-III subtest, index and IQ scores in the newly constituted group. This lowering in test performance is explained in that the new Xhosa first language 15+ years of education group was a less advantaged group than the original Mixed African Language Private/Model C Graduate group, as the new group generally had less advantaged primary school education and had generally studied less at a tertiary level. Overall, these results demonstrate an incremental increase in WAIS-III test performance for sample groups on a continuum of quality of education from least to most advantaged education. This was true for both verbal and non-verbal subtests.
