- Description: More than a century has passed since Canada adopted the first antidumping law in 1904. Similar legislation in most of the major trading nations followed the Canadian legislation prior to and after the World War II. Antidumping provisions were later integrated into the General Agreement on Tariffs and Trade (GATT) after the said war. Today, nearly all developed and developing countries have this type of legislation in place within their municipal legal framework. The subject of antidumping has received growing attention in international trade policy and has become a source of tension between trading nations. This is evident in the substantial increase of antidumping actions since the establishment of the WTO. Antidumping policy has emerged as a significant trade barrier because of its misuse by both developed and developing countries. The primary instruments governing antidumping actions are GATT Article VI and the Antidumping Agreement (ADA). The ADA contains both the substantive and procedural rules governing the interpretation and application of the instrument. Its purpose is to ensure that the instrument is used only as a contingency measure judged upon merit and not as a disguised protectionist device. Given the growing number of countries participating more actively in the world trading system and the notorious misuse of antidumping provisions, there is a vital need to critically analyse the key provisions of the said instruments. This study is an attempt at that academic enterprise. It concludes by giving proposals for future reform of both real and potential future reform of the current WTO antidumping regime.

- Description: Various allegations have been levelled against certain local authorities in South Africa. These allegations include poor governance, maladministration, corruption and poor service delivery. Some of the South African municipalities are unable to deliver sufficient services to the people due to financial instability. On the other side the fact that the municipalities have to generate their own revenue is no longer sufficient. However, government, both national and provincial has to support the municipalities in terms of their capacity to provide services. While government has to provide services to the people to ensure their welfare, people from local communities should also support the continuous provision of `these services by paying for municipal rates and services. These may include services such as water, refuse removal and electricity as well as property taxes. The main issue is that these services are not readily available, for instance water has to be purified. The situation at Mnquma Local Municipality as indicated in the financial and other reports is such that there is a very slow payment of rates and services, which leads to the municipality relying mostly on government grants, and this puts a heavy strain on service delivery by the municipality. Seemingly, it has been long that rates and services have not been paid in Butterworth-even before the restructuring of the municipality (i.e. before the Mnquma Municipality came into being). However, if alternatives could be found to enhance regular payment of rates and services the municipality might improve in terms of its capacity to deliver services.

- Description: This research investigates the factors that affect the performance of Small and Medium Enterprises (SMEs) in the manufacturing sector of Harare, Zimbabwe. To achieve this objective, the research hypothesised that a lack of skilled human resources contributes to the poor performance of SMEs in the manufacturing sector of Harare, Zimbabwe. The research further hypothesized that poor management skills such as human resources, financial management, general management, production management and marketing management result in the poor performance of SMEs in the manufacturing sector of Harare, Zimbabwe. A research proposition was also stated which stipulated that the current hyperinflation environment affects the profitability of SMEs in the manufacturing sector of Harare in terms of profitability. This study is important because SMEs, despite their contributions to the Zimbabwean economy, have not been given due attention as the research of performance has been biased towards large enterprises. The results indicate that managerial aspects which are in short supply have negative effects on the performance of SMEs in the manufacturing sector. The results also indicate that the high rate of inflation and other economic factors such as foreign currency shortage, interest rate and exchange rate affect their performance negatively. Lastly, the study recommends that SMEs, the Zimbabwean government and other supporting institutions such Empretec, ILO and SEDCO take measures to ensure the survival, growth and development of this sector which has the potential to steer the economy. These measures are expected to improve the managerial skills in the SME sector and consequently result in improved performance.

- Description: AIDS Dementia Complex (ADC) is a neurodegenerative disorder implicated in HIV-1 infection that is associated with elevated levels of the neurotoxin, quinolinic acid (QA) which causes a cascade of events to occur, leading to the production of reactive oxygen species (ROS), these being ultimately responsible for oxidative neurotoxicity. In clinical studies, Non-nucleoside reverse transcriptase inhibitors (NNRTIs), efavirenz (EFV) and nevirapine (NVP) have been shown to potentially delay the progressive degeneration of neurons, thus reducing the frequency and neurological deficits associated with ADC. Despite these neuroprotective implications, there is still no biochemical data to demonstrate the mechanisms through which these agents offer neuroprotection. The present study aims to elucidate and further characterize the possible antioxidant and neuroprotective mechanisms of NVP and EFV in vitro and in vivo, using QA-induced neurotoxicity as a model. Research has demonstrated that antioxidants and metal chelators have the ability to offer neuroprotection against free radical induced injury and may be beneficial in the prevention or treatment of neurodegeneration. Hence the antioxidant and metal binding properties of these agents were investigated respectively. Inorganic studies, including the 1, 1-diphenyl-2 picrylhydrazyl (DPPH) assay, show that these agents readily scavenge free radicals in vitro, thus postulating the antioxidant property of these agents. The enhancement of superoxide radical generation and iron mediated Fenton reaction by QA is related to lipid peroxidation in biological systems, the extent of which was assayed using the nitroblue tetrazolium and thiobarbituric acid method respectively. Both agents significantly curtail QA-induced lipid peroxidation and potentially scavenge superoxide anions generated by cyanide in vitro. Furthermore, in vivo results demonstrate the ability of NVP and EFV to protect hippocampal neurons against lipid peroxidation induced by QA and superoxide radicals generated as a consequence thereof. The alleviation of QA-induced oxidative stress in vitro possibly occurs through the binding of iron (II) and / or iron (III), and this argument is further strengthened by the ability of EFV and not NVP to reduce iron (II)-induced lipid peroxidation in vitro directly. In addition the ferrozine and electrochemistry assay were used to measure the extent of iron (II) Fe[superscript 2+] and iron (III) Fe[superscript 3+] chelation activity. Both assays demonstrate that these agents bind iron (II) and iron (III), and prevent redox recycling of iron and subsequent complexation of Fe[superscript 2+] with QA which enhances neuronal damage. Both NNRTIs inhibit the endogenous biosynthesis of QA by inhibiting liver tryptophan 2, 3-dioxygenase activity in vivo and subsequently increasing hippocampal serotonin levels. Furthermore, these agents reduce the turnover of hippocampal serotonin to 5-hydroxyindole acetic acid. NVP and not EFV increase 5-hydroxyindole acetic acid and norepinephrine levels in the hippocampus. The results of the pineal indole metabolism study show that NVP increases the synthesis of melatonin, but decreases N-acetylserotonin, 5-hydroxyindole acetic acid and 5-hydroxytryptophol levels. Furthermore, it shows that EFV decreases 5-hydroxyindole acetic acid and melatonin synthesis. Behavioural studies using a Morris water maze show that the post-treatment of rats with NVP and EFV significantly improves QA-induced spatial memory deficits in the hippocampus. This study therefore provides novel information regarding the neuroprotective mechanisms of NVP and EFV. These findings strengthen the argument that these NNRTIs not only have antiviral effects but possess potential neuroprotective properties, which may contribute to the effectiveness of these drugs in the treatment of ADC.

- Description: This study concerns the analysis of policy, and the statutory and regulatory impact of spatial planning on the land reform programme with emphasis on the land reform settlement plan (LSRP) of the Amathole District Municipality (ADM). There is a brief historical overview of the effect of the policy of spatial segregation in both rural and urban areas of the ADM. This study demonstrates, inter alia, the challenges faced by the ADM in both consolidating and physically integrating communities that were hitherto divided across racial lines. The critical question is whether the ADM has the ability to produce a Spatial Development Framework (SDF), which will be responsive to the needs of the region and serve as a catalyst in reversing the physical distortions caused by the land-planning legislation of the apartheid past. The greatest challenge lies in meeting the developmental aspirations of the Development Facilitation Act, 1995, the Local Government: Municipal Systems Act, 2000 and the National Spatial Development Perspective, 2003. Chapter 1 deals with the purpose, research problem and the method of research, as well as the definition of terms used in this research and literature review. Chapter 2 deals with the evolution of central themes of spatial planning and land reform, spatial development plans and integrated development plans (IDPs), the alignment of Amathole SDF and Eastern Cape Spatial Development Plan and the co-ordination of spatial frameworks. Chapter 3 deals with the composition of the ADM and the evolution of the LRSP, as well as land-tenure reform programmes impacting on the Amathole Municipality region. This chapter analyses the settlement plan against spatial planning legislation, the issue of institutional arrangements and mechanisms of consolidated local planning processes. Chapter 5 deals with the thorny issue of participation of traditional leaders in municipal planning and the government’s land-reform programme. Despite the existence of legislation in this regard, implementation seems to pose some difficulties. This chapter also deals with the co-operative governance framework. Chapter 6 is a concluding chapter dealing with the gaps discovered in the Amathole Municipality in the light of existing legislation. Reference to cases is made to demonstrate the challenges confronting the ADM. One notable aspect is the issue of urban-rural dichotomy and how the two worlds are positioned in their competition for the use of space. It is evident from this research that the post-1994 policy and legislative framework and implementation machinery lacks capacity to change the current form of the apartheid city-planning paradigm, something which impacts immensely on the sustainability of the current human-settlement development programmes. Population dynamics in terms of migration are hugely driven by search for employment opportunities and better services. The efficiency and ability of the municipal spatial evelopment frameworks in directing and dictating the identification of development nodes in its juristic boundary informed by the overarching national policy and legislative framework is key in building a better South Africa.

- Description: This study aims to investigate the possible influence of Western culture on second-year Chinese students at the Nelson Mandela Metropolitan University (NMMU) in 2007 by focusing on their Internet usage. Roland Robertson’s theory of glocalization is employed as the theoretical framework in this study. The research design is qualitative in nature. Individual semi-structured interviews are the method of collecting research data while a thematic analysis is the means of analysing and interpreting the research data. The sample comprises twelve second-year Chinese students who are studying at the Nelson Mandela Metropolitan University (NMMU) in 2007 and have access to the Internet. This study has found that Western culture has exerted multi-faceted influences on the Chinese students through their Internet usage, and that they always negotiate such influences by selecting, adapting and appropriating what is useful in Western culture in an eclectic manner.

- Description: This thesis outlines the design and implementation of a single channel, dual polarization pulsar timing instrument for the Hartebeesthoek Radio Astronomy Observatory (HartRAO). The new timer is designed to be an improved, temporary replacement for the existing device which has been in operation for over 20 years. The existing device is no longer reliable and is di±cult to maintain. The new pulsar timer is designed to provide improved functional- ity, higher sampling speed, greater pulse resolution, more °exibility and easier maintenance over the existing device. The new device is also designed to keeping changes to the observation system to a minimum until a full de-dispersion timer can be implemented at theobservatory. The design makes use of an 8-bit Reduced Instruction Set Computer (RISC) micro-processor with external Random Access Memory (RAM). The instrument includes an IEEE-488 subsystem for interfacing the pulsar timer to the observation computer system. The microcontroller software is written in assembler code to ensure optimal loop execution speed and deterministic code execution for the system. The design path is discussed and problems encountered during the design process are highlighted. Final testing of the new instrument indicates an improvement in the sam- pling rate of 13.6 times and a significant reduction in 60Hz interference over the existing instrument.

- Description: The role and power of ICT today, particularly the Internet, cannot be underestimated. The Internet has a great impact on the business environment, where a large majority of companies and organisations have made substantial investments in an online presence in the form of websites, as well as the IT infrastructure needed to improve business processes. In terms of websites, research has shown that it is critical to identify the target market of the site and the actual users, and to construct the site according to their specific needs and preferences. This is to a large extent the focus of the field of Human Computer Interaction. It therefore makes perfect sense that many software products and websites fail to meet the users‟ needs, as they are designed mainly by Western designers for Eastern and African users. In essence, the failure is due to the fact that the design does not accommodate the cultural behaviours, understandings and preferences of the intended users, thus making it difficult for them to use and adopt them. This has been confirmed by many researchers who have studied various culture dimensions and their relation to Web design. As mentioned, the role of the Internet in terms of its effect in the business world is becoming increasingly important. However, the Internet could prove to play an influential role in the public sector as well and could therefore be used as a critical tool by government in the form of e-Government. Many countries are adopting e-Government initiatives in an attempt to improve their relations within government itself and with their citizens and businesses. This would help them to render better service delivery and at the same time empower the citizens to also participate in the governance of the country itself. The concept for this dissertation was formulated in terms of three key ingredients: e-Government, culture dimensions and Web design. The purpose of this dissertation is to examine the way a specific culture dimension, referred to as the cultural-context dimension, which focuses on the communication process, can impact in Web design. Once this is achieved, it will be possible to determine how this can positively affect the design of the South African e-Government website so that the overall usability of the site may be improved. The improvements will be justified because the site would then match the cultural behaviours, perceptions and Web design preferences of South African users. In short, the goal of this III dissertation is to provide guidelines and recommendations that will improve the South African e-Government website (www.gov.za) by examining anthropologist Edward Hall‟s cultural-context dimension and its role in the Web design process.

- Description: Abalone Haliotis midae farming in South Africa is highly intensive, employing pump-ashore, flow-through systems. Despite the known sensitivity of abalone to water quality, there is only a rudimentary understanding of water quality dynamics on South African abalone farms and its effects on abalone production. Furthermore, the potential for reusing the relatively dilute abalone farm effluent to culture other animal species has not been investigated. This study investigated the dynamics of water quality and growth on a South African abalone farm and assessed the suitability of the effluent for the culture of silver kob Argyrosomus inodorus and bloodworm Arenicola loveni loveni. Monitoring of water quality and abalone growth in abalone tanks revealed that oxygen concentrations decreased, while H⁺ ion and free-ammonia (NH₃) concentration increased in a gradient between the inflow and outflow. Abalone growth was positively correlated with oxygen concentration and negatively correlated with free-ammonia and H⁺ ion concentration. The oxygen (O) concentration of the farm influent was dependent upon the influents’ temperature (T) and was described by the relationship O (mg L⁻¹) = 11.244 – 0.208T (r²=0.74). Linear regression analysis of data collected from abalone farm tanks revealed that the concentration of total ammonia at the outflow of abalone tanks (μg TAN L⁻¹) was dependant upon temperature (°C), flow-rate (L s⁻¹ kg⁻¹ H. midae), abalone size (g) and length of time since the tank was last cleaned (d) (n = 125, r² = 0.80). The production of total ammonia (μg TAN s⁻¹ kg⁻¹) was related to temperature, abalone size and days that the tanks remained un-cleaned (n = 125; r² = 0.81). A diurnal cycle of respiration was evident in abalone tanks with higher oxygen consumption and H+ ion production at night. The oxygen concentration of farm effluent was related to temperature, farm biomass and flow rate by means of a linear regression equation (n = 40; r² = 0.69). The results demonstrated the importance of optimising the flow-rate per unit of biomass for various temperatures and sizes of abalone. As abalone size and temperature cannot be controlled under farm conditions, the flow-rate per unit of biomass which the abalone culture system receives will determine the quality of the culture water. The specific growth rate (0.48 ± 0.01 % BW d⁻¹), mortality (1.8 ± 0.5 %), feed conversion ratio (3.0 ± 0.2) and protein efficiency ratio (1.0 ± 0.1) of silver kob kept in either abalone farm effluent or control seawater for 120 days did not differ significantly (t-test, P>0.05). A 90 day growth trial indicated that abalone farm effluent is a suitable culture medium for bloodworm. Bloodworm supplied with control seawater lost weight at 0.19 ± 0.04 % BW d-1, while those given abalone effluent grew at 0.39 ± 0.07 % BW d⁻¹. Mortality was 6 ± 3 % in effluent and 11 ± 8 % in seawater. The bloodworm were efficient at processing solid waste. Abalone farm effluent initially contained 7.7 ± 13 mg L⁻¹ more suspended solids than control seawater, which contained 3.5 ± 0.5 mg L⁻¹, but after passing through bloodworm systems the concentration in abalone effluent was reduced to only 1.4 ± 3.5 mg L⁻¹ above that in control seawater. Therefore, abalone farm effluent could be reused as a culture medium for both silver kob and bloodworm. Future work is needed to investigate aspects of the feasibility of such systems such as growth rates at different sizes and stocking densities.

- Description: Manual lifting tasks are the predominant means of transporting materials in industry with many of these tasks being performed in confined spaces. Research has tended to focus on the biomechanical implications of working in small spaces with a decided lack of information about the physiological and perceptual responses in these environments. This holistic study therefore investigated the manner in which the human operator responded to conditions where the ceiling height was lowered and reach demands increased. Thirty-two young physically active male subjects (age: 21.55yr; stature: 1810mm) were recruited to complete a 2-way repeated measures experiment during which four lifting protocols where different combinations of ceiling height (‘normal’ or reduced to 1460mm in height) and reach demands (400mm or 800mm) were tested. A crude postural analysis was conducted while physiological responses were detailed and continuously monitored. Perceptual responses were also assessed. The tasks with a ‘normal’ ceiling height (mean compression forces: 2615N; mean shearing forces: 388N) and the greatest reach distance (mean compression forces: 3655N; mean shearing forces: 386N) placed individuals under the highest strain. Mean heart rate (HR) responses were significantly lower (p < 0.05) in the URN condition when compared to the RF condition. Furthermore, HR responses were statistically significantly affected by the height of the ceiling and the reach depth. Statistically significant differences (p< 0.05) in mean tidal volume (VT) occurred in the least (URN) and most (RF) restrictive conditions. Statistically significant differences (p < 0.05) in mean VE were evident between URN and URF, between URN and RF and between RN and RF. Ceiling height and reach demands had a statistically significant effect on all respiratory responses. There was a statistically significant difference in mean oxygen consumption (VO2) between the URN and all other conditions, and between the most restricted task (RF) and all other conditions. Both the effect of ceiling height and reach demands had a statistically statistically significant impact on VO2. Respiratory quotient (RQ) was significantly higher when loads were moved over 800mm compared to 400mm yet ceiling height did not have a statistically significant effect on RQ. Mean energy expenditure was significantly higher in the RF condition compared to the two least restrictive conditions (URN and RN). Statistically significant differences in EE were also evident between URN and RN, and between URN and URF. EE was significantly affected by reductions in ceiling height and increases in reach demands. Perceptually, the RF task (mean ‘Central’ RPE of 11) was perceived to place significantly greater cardiorespiratory demands on the operator compared to the URN (CRPE: 10) and RN (CRPE: 10) conditions. Statistically significant differences in perceived musculoskeletal strain only occurred between URN and RF. The effect of reach was perceived to have a statistically significant effect on both cardiovascular and musculoskeletal demands whereas ceiling height only had a statistically significant effect on musculoskeletal demands. The greatest discomfort was experienced in the lower back with the most intense discomfort occurring in the RN condition.

- Description: The global threat of climate change is one of the most crucial environmental issues facing the world in modern times. In response to this threat, international governments have drafted the Kyoto Protocol which included the Clean Development Mechanism (CDM). The CDM is a scheme which invited developing countries, like South Africa, to become involved in climate change mitigation projects. While South Africa has been identified as an attractive host country for CDM projects, research has revealed that it lags behind other developing countries in this regard. This study provides a theoretical background to the CDM and grounds the subject within the field of Environmental Economics. Following a literature review of factors that could influence the involvement of a municipality in CDM projects, this thesis undertook a case study of the barriers and drivers to CDM implementation within the Nelson Mandela Bay Municipality (NMBM). Use was made of semi-structured interviews, where a questionnaire was used to guide the researcher’s interview process. Five NMBM officers, who were likely to have been involved with CDM project implementation, were interviewed. Data collected was analyzed using a coding technique and was compared and contrasted to the literature in a process of explanation building. It was possible to elicit 14 factors that acted as CDM-barriers; seven that acted as CDM-drivers; and 10 that were required to change within the NMBM to encourage greater CDM involvement. Of the barriers, lack of awareness, poor political will and lack of funding emerged as the most inhibiting. Of the CDM-drivers, the potential financial benefits; ownership of infrastructure capable of producing carbon assets; and technology transfer emerged as the factors most likely to promote CDM involvement. With regards the factors that require change, it emerged that a positive response would result from a proactive stance by National Government on the CDM; the use of Public-Private-Partnerships to facilitate CDM projects; and improved communication and capacity building within the NMBM and the Nelson Mandela Bay business community. The main recommendation offered to the NMBM was for it to draft a Sustainable Development Policy as well as a formal sustainable development strategy to drive a coherent and consolidated approach to the Municipality’s involvement with CDM projects. Further, it was proposed that the NMBM should, lobby National Government for it to promulgate enabling legislation and a framework which would encourage CDM investment in South Africa; and engage with local business to promote the active involvement of the Nelson Mandela Bay with the implementation of CDM projects.

- Description: Banks play a pivotal role in the economic growth and development of countries, primarily through the diversification of risk for both themselves and other economic agents. Interest rate risk is regarded as one of the most prominent financial risks faced by a bank. A large portion of private banks’ revenue stems from net interest income that is generated from the difference between various assets and liabilities that are held on the balance sheet. Fluctuations in the interest rate can alter a bank’s interest income and value, making interest rate risk management vital to its success. The asset and liability committee of a bank is the internal committee charged with the duty of managing the bank’s interest rate risk exposure through the use of various hedging strategies and instruments. This thesis uses a case study methodology to analyse GBS Mutual Bank interest rate risk management. Its specific business circumstances, balance sheet structure and the market conditions over a specified period are used to comment on the practicality of a variety of balance sheet positioning strategies and derivative hedging instruments. The thesis also provides recommendations for the bank’s asset and liability committee in terms of its functions and organisation. It is elucidated that the most practical balance sheet hedging strategies are a volume strategy and immunisation, while the most practical derivative hedging instruments are interest rate futures and interest rate collars. It is found that the bank has a well functioning asset and liability committee whose only encumbrance to its functionality is the inadequacy of the informational technology used to measure, control and manage its interest rate risk position. This thesis concludes by summarising the practicality of the various interest rate risk hedging alternatives available to the GBS Mutual Bank. Implementing a particular strategy or instrument depends, of course, on its asset and liability committee’s decision.

- Description: This study assessed the extent to which exposure to traumatic events affected the traumatic stress response of male and female police officers. A convenience sample of male and female police officers (N = 66: n Male=46, n Female=20) was surveyed at an Eastern Cape police station. The following instruments were used: 1) Biographical questionnaire 2) PTSS-10 scales 3) The 39-item stress incident scale. Findings of this study indicate that the frequency of exposure to stressful incidents especially for more serious events is significant higher than that of Peltzer (2001) study. The four most frequent stressful incidents experienced by all participants were 1) Finding a corpse after murder (86.4 percent), 2) Responding to a scene involving accidental injury of a child (84.8 percent), .3) Finding a corpse (died of natural causes) (84.8 percent), 4) Duty related violence (non-shooting) (84.8 percent ).The four least frequent incidents experienced by participants were: (1) Response to the depressing social situation (71.2 percent), (2) Dragging of a corpse (74.2 percent), (3) Taking a life in the line of duty (75.8 percent), (4) Violent death of a colleague (77.3 percent ).Female participants results indicated a positive relationship between frequency of stressful incidents and total threat, anxiety, helplessness and PTSS-scale , where male participants’ results indicate no significant relationship between frequency of stressful incidents and total threat, anxiety, helplessness and PTSS-scale. Findings on male participants however indicate a positive relationship between years of service in police, age of police officers and PTSS-scale, while female participants’ results indicated no relationship between years of service in the police, age of police officer and PTSS-scale.

- Description: Researchers hold numerous perceptions of the educational aspirations and future career choices of teenage girls. Studies argue that factors such as the curriculum, teachers' and parents' attitudes, the impact of HIV/AIDS, and teenage pregnancy, influence girls' future educational and occupational hopes and dreams either positively or negatively. Other researchers claim that learners' career choice is limited by their potential and school performance. The existing literature also suggests that girls have lower self-esteem and levels of achievement than boys. This research seeks to gain insight into high school girls' perceived academic and vocational prospects. The research was carried out in an interpretive paradigm. Six secondary school female learners from one school participated in the study. Semistructured interviews were the core method of data collection, supplemented by questionnaires and a focus group interview. As teenagers, the girls were expected to already have started to think about their future hopes and dreams. The findings revealed that all the girls seemed to experience school as a place where they could acquire knowledge about what they needed to make them autonomous and successful in adult life. For them, their parents remained their major significant others. They regarded fear of poverty as a major factor motivating them to achieve their educational and vocational aspirations. Peer pressure appeared not to be a major determinant of these girls' successes in school. The girls believed that there is a relationship between their academic performance and their future vocational choice. In addition, the girls did not see boys as a threat to their climbing the ladder of success.

- Description: The present study explores Rhodes students' perceptions and attitudes towards HIV/Aids issues. This study focuses on risk behaviour, stigmatisation, social perceptions and voluntary counselling and HIV testing (VCT). There is a lack of research on student attitudes, knowledge and behaviour at Rhodes University. It was therefore deemed pertinent to research this topic in that context. It was envisaged that the study would provide insights to be used in the formulation of improved strategies for HIV/Aids programs and education, ultimately impacting on the exponential increase of the pandemic in the Southern African region. A sample of six hundred and seventy five Rhodes University undergraduates completed a survey and its findings were interpreted in terms of relevant literature. A mixed methods approach using qualitative and quantitative methods was used. A focus group consisting of seven post-graduate students informed the development of the survey along with relevant literature. Four departments from the faculties of Commerce, Humanities, Science and Law were randomly sampled for the survey phase. Statistica was used to calculate descriptive statistics while the chi-square statistic was applied to examine the relationships between the variables. The findings show that the majority of students have high intention levels in planning to use preventative behaviour. However, in practise, this may not be the case. Many students feel that they belong to high or medium risk groups, as opposed to the low-risk groups. In terms of motivation levels, only sixty three percent of students are highly motivated to protect themselves from HIV/Aids and one third of respondents felt that they could not ask their partner to accompany them for an HIV/Aids test. In addition, students who had received VCT were more likely to be positive about the counselling process.

The tax implications of non-resident sportspersons performing and earning an income in South Africa

- Description: As the number of non-resident sports persons competing in South Africa increases so does the need to tax them more effectively. It was for this reason that the South African legislature decided to insert Part IlIA into the Income Tax Act which regulates the taxation of non-resident sports persons in South Africa. The new tax on foreign sports persons, which came into effect during August 2006, is a withholding tax placing the onus upon the organizer of the event to withhold the tax portion of the payment to the non-resident sportsperson and pay it over to the revenue services. The rate of taxation has been set at 15 percent on all amounts received by or accruing to a foreign sportsperson. The question which the research addressed is whether this new tax will prove to be an effective tax, both from the point of view of its equity and the administration of the tax. In order to determine the impact of the new tax, it was compared to similar taxes implemented in the United Kingdom and Australia and also to other withholding taxes levied in South Africa. The new tax was also measured against a theoretical model for effectiveness, compared to the pre-August 2006 situation and to the taxation of resident sportsmen and women, using hypothetical examples. The major shortcomings of the new withholding tax are the uncertainty with regard to the intention of the legislature on matters such as the taxation of capital income versus revenue income, the question whether payments to support staff are included in the ambit of the new tax, the taxation of the award of assets in lieu of cash payments and the definition of a resident. A further area of concern is that the rate of taxation of 15 percent appears to be too low and creates horizontal inequity between the taxation of resident and non-resident sports persons. The new tax on non-resident sports persons may have its shortcomings but, depending upon the administrative and support structures put in place to deal with it, will be an effective tax. The rate at which the tax is levied could result in a less tax being collected than before but, with the reduced administrative cost of tax collection, the effective/statutory ratio of the tax could well be much higher than it was. This is a new tax in South Africa and certain initial problems are inevitable and will undoubtedly be solved as the administrators gain experience and as the case law governing this tax develops. , KMBT_363

- Description: In this study an exploration was conducted of change and transformation at an institution of higher education in South Africa using Anstey’s conceptual framework. This framework incorporated the work of major change theorists as well as the balanced scorecard of Kaplan and Norton. A quantitative and exploratory approach was used. The research question for this study was formulated as follows: How successful was the organizational transformation process at the newly established university in the period 2003 – 2007? The first objective of the study was to describe the organizational transformation process as it unfolded at the newly established university. The second objective was to evaluate the success of the organizational transformation process by using Anstey’s conceptual framework. Eight factors were identified in Anstey’s framework according to which the success of the merger was analyzed. These factors were: constructive unease; harnessed urgency; clear purpose; challenging vision with clear measurable objectives; champions at all levels; culture and community; competitive competencies; coherent strategy, and communication and consultation. A computerized survey tool was utilized to design a structured questionnaire with both fixed response and open-ended questions. Some 13 percent of the employees responded to the questionnaire. The internal consistency of the scores derived from the instrument was confirmed using Cronbach’s alpha. Descriptive statistics revealed that 62.5 percent of factor scores were neutral and 37.5 percent negative with regard to staffs’ perceptions of the merger. Inferential statistics disclosed that academic staff viewed the merger more negatively on factor 3 challenging vision with clear measurable objectives than their administrative colleagues. The total success of the merger can be summarized by the following statement of one of the participants ‘If the NMMU merger is compared to other mergers in Higher Education in South Africa then it is clear that, from a systems and procedural perspective, it was managed satisfactory. Unfortunately the ‘people’ dimension of the merger did not feature as a priority and many staff members were alienated as a result of this.’ The limitation of the study was the small sample size. This study was also contextual in nature, meaning that it focused on the transformation process as it unfolded at a specific university in South African between the years 2003 – 2007. No results generated in this study can be generalized as they only presented a shot-in-time reflecting the transformation process at a particular organization at a particular period in time. This study also confirmed the usefulness of Anstey’s conceptual framework in assessing transformation at an institution of higher education.

- Description: There is a common perception that media depiction of mental health and illness is overwhelmingly negative and inaccurate. Media portrayal of mental illness is also viewed as an important element in forming and influencing society’s attitudes towards mental health issues, although there is no causal link to prove this. People with mental illness are most commonly shown as being violent and aggressive. Movie stereotypes that contribute to the stigmatisation of mentally ill persons include the mental patient as rebellious free spirit, homicidal maniac, seductress, enlightened member of society, narcissistic parasite, and zoo specimen. The profession of psychiatry is, has always been, and will likely continue to be a much enjoyed subject among filmmakers and their audiences, as it tends to provide exciting and emotionally compelling opportunities to portray personal struggles feared by most of humanity. This research will analyse the entertainment media in an attempt to provide evidence to support the above statement. The research will, furthermore, analyse the manner in which entertainment media represent the mentally ill with reference to popular films invariably produced in the US

- Description: Lean philosophy is based on the continuous quest to improve the organisation’s processes by creating a culture and operating principles which eliminate all non value adding activities within organisation‘s processes. Manufacturing firms consider the adoption of the Lean tools as basic requirements for achieving World Class operational excellence or Best Practice. For some time, lean has been used by the manufacturing organizations. Most organizations understand that lean will help them survive global competition and stay in business. According to Hanna (2007:1), service industries, in general, are a long way behind manufacturing in terms of operations and improvements, and not all lean manufacturing ideas translate from the factory floor to office cubicle. The objective of this study is to investigate how lean manufacturing tools can be used to improve efficiency, customer service and enhance the embedding of a continuous improvement culture in the South African Revenue Services East London office Taxpayer Service business area. The activities that took place in the Taxpayer Service business area from 21 July 2008 until 31 October 2008 were observed. During the observation period, taxpayer services staff members were engaged formally, using surveys to assess their underlying mindset and behaviour as well as informally, using unstructured interviews to solicit more information on activities taking place and the reasoning behind certain actions. The movements of taxpayers who visited the branch office were monitored and the time it took for taxpayers to be assisted was measured as well as the time it took taxpayers to be assisted by a service agent or service consultant. To see if the available resources were used efficiently, the numbers of service channels available were compared to the number of service channels occupied. The results of the survey and observations are analysed and interpreted.
