- Description: The aim of this study was to determine whether coping strategies of police officers help moderate the outcome of burnout resulting from job stress. The nature of the job demands of police officers is such that they may experience high levels of stress. A convenience sample (N = 89: n Males = 58; n Female = 29) of police officers in police stations in the Eastern Cape was surveyed. The Maslach Burnout Inventory – General Survey, Police Stress Inventory and COPE questionnaire were administered. Results for all the participants indicate that when the occupational stressor Lack of Resources occurs police officers implement Avoidance Coping (COPE) as a strategy, which leads to the experience of Exhaustion. Results also indicate that police officers use Active Coping, Cognitive Coping and Turning to Religion as means of moderating the stress-burnout relationship. Results also show that the coping strategy Avoidance Coping, used by male officers lead to Cynicism. When female police officers experience Job Demands and a Lack of Resources they make use of Seeking Emotional Support as a coping strategy. Male police officers were shown to make use of Active Coping as a strategy to regulate the stress-burnout relationship while female police officers implemented Active Coping and Turning to Religion to act as a buffer between job stress and burnout.

- Description: Language rights in South Africa are entrenched in the Constitution of South Africa (Chapter 1, Section 6, Constitution of the Republic of South Africa, 1996). However, the concomitant infrastructure and organisational realities make this policy difficult to implement, especially in law courts (Kaschula and Ralarala 2004). Creating effective communicative environments has historically been constrained by lack of effective training of legal practitioners and by the lack of capacity for building translation structures. With the advancement of technology, potential solutions are becoming more apparent and it is incumbent upon the academic community to embark on a rigorous investigation into possible solutions and how these Information Communication Technology (ICT) solutions could be applied to the execution of justice in South African law courts. This article aims to open the discourse of possible solutions, via assessments of computer based translation solutions, ICT context simulations and other potential opportunities. The authors hope to initiate the interest of other language and legal practitioners to explore how the new technological capabilities could be harnessed to support the entrenchment of language rights in our law courts.

- Description: The limited attention afforded to push/pull activities and the motion phases (initial, sustained and ending) characteristic of these tasks has prompted a research focus in this area. The present study examined biomechanical responses in the form of hand forces during dynamic submaximal trolley pushing and pulling. Participants pushed/pulled loads of 100, 200 and 300 kg on the level (determining impact of load) or pushed 100 kg along a 12° ramp (uphill and downhill- determining impact of gradient). During level exertions significant differences (p<0.05) in hand forces occurred between loads of 100 and 200 kg, and 100 and 300 kg for initial and sustained forces but not ending forces. Values were similar for pushing and pulling at respective loads and motion phases. Strong correlations indicate that initial forces can be used to accurately estimate sustained and ending forces. Importantly, correct technique is essential in force reduction. Forces were highest during uphill initial and sustained phases and the downhill sustained phase. For the initial phase, the forces were highest during uphill pushing (86.5 ± 25.73 N); for the sustained phase, there was no difference between uphill and downhill forces but level forces were significantly lower (18.19 ± 8.09 N) than either of the other two conditions; for the ending phase, the highest forces were produced during downhill pushing (-53.34 ± 13.65N). As sustained forces equaled or exceeded initial forces for uphill and downhill efforts, consideration of sustained forces may be appropriate in determining the inherent potential risk of graded pushing.

- Description: HIV and AIDS are casting a dark shadow over the future of many developing countries in the world. Since the first diagnosis of AIDS cases, South Africa has become one of the countries most infected with the HIV and AIDS pandemic, with about five million people living with HIV and AIDS. HIV prevalence is high in the age group 15 to 49 years, attacking people in the most productive years of their lives, Africans are the most significant racial group, affected and the Eastern Cape rates sixth in terms of HIV prevalence in the country. Demographically, HIV and AIDS affects the structure of the population, including learner and educator populations, as HIV and AIDS impact on the demand and supply of education. Schools are negatively and diversely impacted by the new challenges of the pandemic, preventing schools from achieving their goals. South Africa is struggling with a shortage of educators in the school system, especially the key areas of science and mathematics. The number of potential learners is expected to decline as AIDS orphans and other vulnerable children drop out of school, relocate, do not enrol, or are forced to withdraw from the school system. These factors lead to a poor morale and unproductivity among educators and learners, causing management problems in education for school principals and a decline in the quality and efficiency of education. While there is still no known cure for HIV and AIDS, the only solution in curbing the spread of the pandemic is through education and changing the social behaviours and mindset of people. However, HIV and AIDS prevention interventions have clearly been ineffective, as infection rates are soaring. As HIV and AIDS infection rates escalates, a more urgent response by school principals is needed to address the unique demands of the pandemic and establish where HIV and AIDS interventions will be most successful. The current study had three major aims. The aims were to explore how school principals in the Eastern Cape perceive the HIV and AIDS pandemic; describe in detail how school principals in the Eastern Cape respond to the HIV and AIDS pandemic; and to formulate recommendations based on the findings of the research that will assist school principals in effectively managing the pandemic at school level. The sample consisted of twelve school principals from different schools in the urban areas of Nelson Mandela Bay and the rural Keiskammahoek area. A qualitative method was selected to capture the unique experiences of school principals. In-depth, unstructured interviews were conducted to gather information. Thereafter, the interviews were transcribed verbatim, analysed and interpreted to gain a deeper understanding of the research phenomenon. The findings of the study revealed that the majority of school principals had limited knowledge only of the HIV and AIDS pandemic, and perceived the pandemic in a non-constructive manner, as an imminent future problem. In fact, many school principals were ambiguous, contradictory and discriminatory in their discussion in their responses to the pandemic, first denying the presence of AIDS cases in their schools, then shifting the blame for the spread of HIV and AIDS in their schools to others. These school principals were clearly unaware that they were being discriminatory and secretive about the pandemic through denial and blaming others and that their attitudes were fuelling stigmatization and discrimination. The school principals acknowledged that much more still needed to be done in terms of management and leadership to effectively mitigate the effects of the pandemic in their schools. While school principals did their best in dealing with HIV and AIDS related problems at their schools, they clearly lacked the necessary skills, training and knowledge to devise long-term strategies to deal effectively and pro-actively with the problems related to the pandemic. Therefore a more transformational leadership and management approach is required by school principals in dealing with the pandemic in their schools, in order to render them effective leaders.

- Description: Admissions assessment batteries at most South African higher education institutions augment matriculation results with assessment data from cognitive and non-cognitive measures, in order to identify potentially successful students. The Motivated Strategies for Learning Questionnaire (MSLQ) is a non-cognitive measure, developed in the United States of America to assess the motivational orientation and use of learning strategies among college students. Numerous international studies have confirmed the reliability and validity of the MSLQ. Presently only three quantitative studies have been conducted in the South African higher education context, and in these, researchers have focused on the predictive validity, construct validity and reliability of the MSLQ when used with multicultural and multilingual groups of test-takers. An overview of these studies revealed a confirmation of adequate reliability of the MSLQ, and whereas it was established that nine of the fifteen subscales of the MSLQ are significantly related to the academic success of undergraduate students, limited support was found for the construct validity of the measure. As a result of these findings, a lack of qualitative methods for confirming or disconfirming the quantitative results was noted. The general aim of this study was to explore the applicability of the MSLQ in a higher education South African context, with respect to aspects related to bias, through assessing the item content with specific reference to language and cultural appropriateness. This was to ensure that items on the MSLQ did not favour or disadvantage any cultural and language groups. Investigations in this regard are a necessity in a country like South Africa in an effort to promote fair assessment practices. In order to achieve the above-mentioned aim, a quantitative and qualitative approach was utilised following an exploratory-descriptive research method. The researcher employed a non-probability, purposive sampling procedure to select post-graduate participants employed at the Nelson Mandela Metropolitan University (NMMU) to act as expert reviewers. A Bias Review Form was the primary mode of data collection and this enabled the researcher to collect the biographical details of the expert reviewers, their ratings of the language and cultural appropriateness of each item, and their comments, suggestions and recommendations for improving identified problematic items. Descriptive statistics were used to analyse the reviewers’ responses to the short biographical questionnaire included on the Bias Review Form, while frequency counts were calculated based on the reviewers’ responses to the language and cultural appropriateness of each item. The reviewers’ comments were analyzed into themes using Tesch’s model of content analysis. Three main themes relating to potential bias were identified, namely, language, culture and item characteristics. Guba’s model was employed for assessing the trustworthiness of the qualitative data and for data verification.

- Description: The objective of the study was to evaluate cow reproductive performance in the sweetveld and sourveld communal grazing areas of the Eastern Cape Province, South Africa. In the first experiment, farmer perceptions were obtained using participatory rural appraisals. Farmers ranked lack of fences, tick-borne diseases, poor animal condition during winter and poor breeding practices, respectively as major constraints limiting cattle production in the Eastern Cape. Cattle, sheep and goats, in that order, were ranked as the most important livestock species and were mainly kept for meat, cash and ceremonies, respectively. The non-descript cattle breed was the most common breed found in the smallholder areas. Most farmers preferred Nguni breed because of its adaptive attributes. In the second experiment, structured questionnaires were administered, between June and August 2006, to a total of 551 farmers from 10 communities of the Eastern Cape. There was a significant association (P<0.05) between the use of pregnancy diagnoses and community. About 87 and 77 % of the interviewed farmers did not respond on the extent of pregnancy and calving rates in their herds. A higher proportion of farmers from Hekele (51%) and from Upper Mnxe (45.3%) communities reported low number of bulls as a major constraint to cow reproductive performance. Body condition and ovarian activity were measured in the sweet and sour veld types. Body condition score of animals was measured from March iii 2007 until January 2008 and ovarian activity of cows was performed by a veterinarian through rectal palpation in June, August and October 2007 and January 2008. From March to July, there was a marked decline in body condition on both veld types. In the sweetveld, body condition improved from September until January, whereas in the sourveld the improvement in body condition started in October. The cows in both veld types conceived throughout the year. Most cows in the sweetveld were cycling in January and August (P<0.05) whereas in the sourveld there was no distinct period when the animals were cycling. Overall, there were no differences in the proportion of cows that were cycling between the sour and sweet veldts (P>0.05). There were more cows cycling in sourveld in October than in the sweetveld. Reproductive performance of cows in communal areas could, therefore, be determined by levels and quality of nutrition. Keywords: Participatory rural appraisals; Structured questionnaires; Farmer participation; Farmer perceptions; Body condition scoring; Ovarian activity; Pregnancy diagnoses.

- Description: This thesis examines the underreporting of sexual violence against women in the Camdeboo. It is based on a survey of 971 women living in the Camdeboo aged fifteen and older. The thesis considers, with reference to relevant secondary literature, methodological issues pertinent to conducting survey research into violence against women. While many survey researchers into violence against women argue that behaviourally specific questions lead to higher rates of disclosure, the survey on which this thesis is based employed complex and open-ended questions to allow respondents to record their own definitions of physical and sexual abuse. 31,2 percent of the women surveyed disclosed having experienced sexual abuse, but 76,7 percent did not report this abuse to the police. The thesis explores the patterns of sexual abuse of women in the Camdeboo and the factors influencing the underreporting of such abuse. While it was possible to establish correlations between certain socio-demographic variables and the underreporting of sexual abuse, such correlations should be treated with caution. The survey found that women were far more likely to report (and disclose) sexual assaults by strangers than by people known to them, particularly intimate partners. Sexual abuse in intimate relations was found to be strongly associated with physical abuse, and women who had experienced sexual and physical abuse within intimate relationships were more likely to report their physical abuse to the police than their sexual abuse. However, the majority of women, particularly poor and economically dependent women, believed that reporting their intimate partner abuse to the police would not end it, and might even place them at greater risk. The evidence suggests that these perceptions are accurate. Under current circumstances, reporting sexual abuse to the police may not be the best help-seeking strategy available to many sexually abused women, and alternative sources of help may be more appropriate. Consideration should be given to directing more resources into such alternatives.

- Description: On the basis of clinical studies, some researchers have advocated that the neurohormone and antioxidant melatonin, shown to possess intrinsic anticancer properties, be used as co-therapy in cancer patients being treated with the antineoplastic agent 5-fluorouracil, as increased patient survival times and enhanced quality of life have been observed. The focus of this research was thus to investigate the mechanisms of this seemingly beneficial drug interaction between 5-fluorouracil and melatonin. Metabolism studies were undertaken, in which it was established that there is no hepatic metabolic drug interaction between these agents by cytochrome P450, and that neither agent alters the activity of this enzyme system. Co-therapy with melatonin is thus unlikely to alter plasma levels of 5-fluorouracil by this mechanism. Novel mechanisms by which 5-fluorouracil is toxic were elucidated, such as the induction of lipid peroxidation, due to the formation of reactive oxygen species; decreases in brain serotonin, dopamine and norepinephrine levels, possibly leading to depression; hippocampal shrinkage and morphological alterations and lysis of hippocampal cells, which may underlie cognitive impairment; and a reduction in the nociceptive threshold when administered acutely. All these deleterious effects are attenuated by the co-administration of melatonin, suggesting that the agent exhibits antidepressive and analgesic properties, in addition to its known antioxidative and free radical-scavenging abilities. This suggests that melatonin cotherapy can significantly decrease 5-fluorouracil-induced toxicity, but this may also exert a protective effect on cancer cells and thus compromise the anticancer efficacy of 5-fluorouracil. It was, furthermore, found that stimulation of indoleamine 2,3-dioxygenase activity, mediated by increases in superoxide anion and interferon-γ levels, may underlie resistance to 5-fluorouracil therapy. Melatonin was shown to increase superoxide anion levels in vivo, and this is believed to be by conversion to the metabolite and known oxidant 6- hydroxymelatonin. This highlights that the possible deleterious effects of melatonin metabolites should be studied further. Serum corticosterone levels and cytokine profiles are unaltered by both 5-FU and melatonin, suggesting that these agents may be used by HIV infected individuals without promoting the progression to AIDS. It can thus be concluded that melatonin co-therapy is potentially useful in countering 5-fluorouracil toxicity.

- Description: The South African Revenue Services (SARS) is an amalgamation of the former Departments of Customs and Excise, and the Receiver of Revenue. SARS obtained full autonomy from the Government in October 1997 in order for it to administer its own affairs. SARS has since made great strides in transforming its people and technology, although some growing pains are recently being experienced, i.e. the “retention question”. The problem statement, “What strategies can be implemented for retaining skilled employees within SARS Customs” is derived from a multitude of problematic issues currently being experienced world wide. Problem areas particular to South Africa, include: the mass exodus of white skilled labour; baby-boomers (aged 60 – 65) nearing retirement, affirmative action, employment equity, and a general lack of skills in the employment industry. An employee engagement survey (2007) conducted at SARS, shows figures that further exacerbates the problem. The objectives of the research were therefore, to conduct a literature study of employee retention strategies, investigate the research strategies currently being employed at SARS, the reasons for the low levels of employee engagement and to develop a strategic model for employee retention for use at SARS Customs in the Eastern Cape Region of South Africa The study takes the form of a case study, using quantitative and qualitative methods of research. A questionnaire was distributed to respondents, the results of which were analysed and presented. The findings show that SARS Customs is in a good position with regards to pay and benefits. Areas that require attention though are training, development and career management, effective supervision, and day-to-day activities.

- Description: Companies are constantly expected to be more competitive while working in an environment in which time and cost are limited, thereby preventing such companies from taking the time required to be responsive. It is, therefore, important that companies understand that conventional knowledge and methods will not serve unless there is a concerted focus on improvement of organisational performance toward fulfilling increased expectations, not just maintaining that which is comfortable. A more sustainable approach may be the introduction of lean manufacturing techniques. The lean manufacturing process is one that continuously strives to eliminate waste, thereby increasing the percentage of time that may be devoted to value-adding activities. Lean manufacturing principles were applied in the Can Coating Plant of Duco Speciality Coatings. This study was intended to identify waste in the current production process in the Can Coating Plant and then to use lean tools and principles to eliminate such waste. Implementation of these lean tools proved to result in a leaner and more value-adding process. The new process rendered a positive result on Duco Coating’s costs, quality and product performance. Recommendations on further improvements were also offered.

- 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. Keywords: Global Warming, Kyoto Protocol, Clean Development Mechanism, Sustainable Development, Environmental Economics, Public Sector, Nelson Mandela Bay Municipality.

- Description: This study addressed the role of the mother-daughter relationship on the daughter‟s development of the capacity for intimacy with a romantic partner. The objective of this study was to examine whether separateness in mother-daughter interactions was related to romantic intimacy (sexual and non-sexual intimacy) in romantic relationships. The following instruments were used: 1) Socio-demographic questionnaire; 2) Competence in Mother-Daughter Relationship Questionnaire (ICQ-M) and 3) Personal Assessment of Intimacy Questionnaire (PAIR). 179 adolescent female university students participated in this study most of who were between the ages of 20 and 24. The results indicated that a positive relationship existed between separateness and sexual intimacy (r=.688, p<.01) as well as separateness and non-sexual intimacy (r=.598, p<.01). A positive relationship between connectedness and non-sexual intimacy (r=.468, p<.01) was also observed, however no correlation was observed between connectedness and sexual intimacy. These findings indicate that separateness in mother-daughter interactions has a definite effect on the different dimensions of romantic intimacy. Therefore, late adolescent women who possess the ability to assert themselves and express differences between themselves and their mothers are not as apprehensive as their peers when it comes to romantic intimacy with a partner.

- Description: The sugar cane industry forms a significant portion of the South African economy, and unlike many other countries the harvesting of sugar cane in South Africa remains manual in nature. The focus of the present study was therefore on the assessment of spinal kinematics (range of motion, velocities and accelerations in all three cardinal planes) during the harvesting process. Eight workers were recruited from the Illovo Esperanza farm in Kwa-zulu Natal as subjects for the study. The experimental protocol was conducted in situ and required subjects to cut the sugar cane using specially modified knives as they would under normal harvesting conditions. The motion performance was quantified using the lumbar motion monitor (LMM), a triaxial electrogoniometer. Results indicate that the harvesting of sugar cane places excessive demands on the spine. During cutting, subjects were required to maintain the spine in a high degree of flexion throughout the task which also demonstrated significant twisting and lateral bending. Of particular concern were the high lateral velocities (ranging between 50 and 90 m.s-1), as this is a key risk factor in the development of lower back pain. It is evident from these results that new techniques of harvesting sugar cane are essential to reduce the rate of injury within this industry.

- Description: New Caledonia, an archipelago situated in the South-West Pacific Ocean has a very high biodiversity of which many flora and fauna species are endemic, and is therefore considered as one of the world hotspots for the biodiversity conservation. Sclerophyll forests, one of the five main vegetation types occurring on the island are mainly threatened by anthropogenic activities. Rusa deer (Cervus timorensis russa) were introduced into New Caledonia from Java in 1870. They have colonised all the biotopes of the main island, and represent one of the major threats to the New Caledonian sclerophyll forests. Currently, there is a lack of management tools to monitor the trends of rusa deer in New Caledonian sclerophyll forests. To test monitoring methods for use as management tools, six sclerophyll forests study sites were studied using direct census methods (i.e. spotlight count and drive count), indirect census methods (i.e. faecal standing crop method) and three indices (i.e. the faecal pellet groups index, the browsing index and the antler rubbing index). The faecal pellet groups index is based on sampling pellet groups in plots along transects. To ensure reliable data collection with a coefficient of variation of the mean number of intact faecal pellet groups per plot per transect of less than 20 percent, my study indicated that 15 plots per transect and 20 transects per sites should be sampled in New Caledonian sclerophyll forests whereas previous studies conducted in New Zealand indicated that a minimum of 25 plots per transect and of 18 transects per site should be sampled. The advantages of reducing the number of plots per transect and of transects per site is that it reduces the expenses (e.g. time, finance) and the bias due to data collection (e.g. fatigue, boredom and visual activity) which will improve the precision of the data recorded. Estimates of rusa deer density obtained from the census methods were not correlated (r = - 0.425, df = 4, P = 0.401) due to my small sample size. The reliability of these estimates is questionable because of biases. Previous publications have shown that biases are difficult to avoid when using direct census methods and that it is difficult to estimate the size of animal populations with accuracy and precision. The faecal standing crop method was subjected to bias because the estimation of the decay rate and the defecation rate were unreliable. These methods were not recommended for rusa deer management in New Caledonian sclerophyll forests. Of the three indices tested, the faecal pellet groups index and the browsing index based on unpalatable browse species were the most reliable as the confidence intervals of these two indices were small (i.e. from ±0.08 to ±0.11 for the faecal pellet groups index; from ±0.04 to ±0.27 for the browsing index of unpalatable browse species), and they also showed significant correlations with a subjective ranking of the rusa deer density based on expert knowledge (rs = 0.829, df = 4, P = 0.042 and rs = 0.829, df = 4, P = 0.042 respectively). These two indices appear to show the most promise for use as management tools, as they could reliably track local variations of rusa deer densities on the sclerophyll forests. These two indices could be used by wildlife technicians in New Caledonia to establish management plans of rusa deer populations which rely on participative management involving the stakeholders (e.g. hunters, forest managers, local communities). We believe that the faecal pellet groups index and the browsing index could be useful to monitor rusa deer populations in New Caledonian sclerophyll forests, and meet conservation and hunting objectives of the local population and authorities. Management tools such as culling and hunting operations will be implemented in New Caledonian sclerophyll forests where monitoring of indices I recommended show an increase in the deer population. Stakeholders will be involved in the implementation of the monitoring tools (i.e. indices) and of the management tools (e.g. culling and hunting operations, fencing) but also in decision making for the management of the rusa deer in New Caledonian sclerophyll forests.

- Description: The search for service and product quality has come to the forefront of business studies as the most important consumer trend of the past two decades. Studies conducted indicate that the 1990s saw a dramatic change in customer expectations concerning service quality and standards with a corresponding increase in the number of complaints from disgruntled customers. In response to this, many organisations have established customer care and complaints management services to respond to the need of customers. A substantial amount of literature exists on the subject of complaints management and its role in service quality, however, the focus has been on organisations in the private sector. The research undertaken in this paper aimed to investigate the role of complaints management systems (CMS) to evaluate service quality. The focus of this research was on local government with special attention on George Municipality. A literature review was done to establish the importance of service quality for local government as well as to investigate the link between an effective complaints management system and improvement in service quality. Furthermore, it was necessary to investigate the characteristics, design and implementation of an effective complaints management system. A questionnaire was developed in order to obtain primary data from a selected sample group. The data obtained from the questionnaire was statistically analysed and interpreted. The core findings from the analysed questionnaire indicated the following: service quality is relevant in local government; there is no clear method to measure service quality; no formal and structured complaints management system exist, and the implementation of an effective complaints management system will both improve service delivery and provide benefits to all involved. iv This study recommends that: service quality standards and measurement be of strategic importance to local government; customers should be consulted and involved when determining the service quality standards and measurement, and an organised and structured complaints management system that seeks to address all complaints in order to improve the level of service quality to customers be developed. Finally, the success of the CMS will depend on management’s commitment to change on a continuous basis as well as the degree to which management proactively resolves customer complaint through the involvement of the customer.

- Description: Ad-Hoc mesh networks offer great promise. Low-cost ad-hoc mesh networks can be built using popular IEEE 802.11 equipment, but such networks are unable to guarantee each node a fair share of bandwidth. Furthermore, hidden node problems cause collisions which can cripple the throughput of a network. This research proposes a novel mechanism which is able to overcome hidden node problems and provide fair bandwidth sharing among nodes on ad-hoc 802.11 networks, and can be implemented on existing network devices. The scheme uses TDM (time division multiplexing) with slot reservation. A distributed beacon packet latency measurement mechanism is used to achieve node synchronisation. The distributed nature of the mechanism makes it applicable to ad-hoc 802.11 networks, which can either grow or fragment dynamically.

- Description: The issue of refugees in South Africa has come under the spotlight recently, particularly in the light of the xenophobic violence that swept the country in 2008. As a Baptist pastor, working in a congregation which has a vital ministry towards refugees, the writer became aware that only a handful of Baptist congregations in the Western Cape had a similar concern for refugees and asylum seekers. These observations raised the question of ministry to refugees on the part of Baptist churches in SA. As Baptist churches adhere to the principle of the supremacy of Scripture, the motivation for churches to minister to refugees should to be based upon biblical theology. This dissertation seeks to provide such a biblical theology of ministry to refugees that can in turn provide a basis from which local congregation can develop such ministry. To provide the context of refugees in SA, this study begins by outlining the phenomenon of refugees in the context of SA, as well as the conditions experienced by refugees. This dissertation further seeks to delineate a number of Baptist principles that relate to the issue of Baptist churches and ministry to refugees. It also seeks to look at the role that various Baptist agencies such as the Baptist Union of Southern Africa (BUSA) and the Western Province Baptist Association have to play in ministry to refugees. The study then goes on to discuss biblical material from both the Old and New The issue of refugees in South Africa has come under the spotlight recently, particularly in the light of the xenophobic violence that swept the country in 2008.

- Description: Behind the dragged-out confrontations around the SABC are a politics of paralysis. That's not necessarily a bad thing if the alternative is the broadcaster being a tool of a single particular force. But it's also not exactly first prize for South Africans. Power is divided across so many centres that no single force has been able to easily prevail on SABC during the year.

- Description: The Orange River, South Africa's largest river, is a critical water resource for the country. In spite of the clear economic benefits of regulating river flows through a series of impoundments, one of the significant undesirable ecological consequences of this regulation has been the regular outbreaks of the pest blackfly species Simulium chutteri and S. damnosum s.l. (Diptera: Simuliidae). The current control programme, carried out by the South African National Department of Agriculture, uses regular applications, by helicopter, of the target-specific bacterial larvicide Bacillus thuringiensis var. israelensis. While cost-benefit analyses show significant benefits to the control programme, benefits could potentially be further increased through applying smaller volumes of larvicide in an optimised manner, which incorporates upstream residual amounts of pesticide through downstream carry. Using an optimisation technique applied in the West African Onchocerciasis Control Programme, to a 136 km stretch of the Orange River which includes 31 blackfly breeding sites, we demonstrate that 28.5% less larvicide could be used to potentially achieve the same control of blackfly. This translates into potential annual savings of between R540 000 and R1 800 000. A comparison of larvicide volumes estimated using traditional vs. optimised approaches at different discharges, illustrates that the savings on optimisation decline linearly with increasing flow volumes. Larvicide applications at the lowest discharge considered (40 m3·s-1) showed the greatest benefits from optimisations, with benefits remaining but decreasing to a theoretical 30% up to median flows of 100 m3·s-1. Given that almost 70% of flows in July are less than 100 m3·s-1, we suggest that an optimised approach is appropriate for the Orange River Blackfly Control Programme, particularly for flow volumes of less than 100 m3·s-1. We recommend that trials be undertaken over two reaches of the Orange River, one using the traditional approach, and another using the optimised approach, to test the efficacy of using optimised volumes of B.t.i.

- Description: The focus of this thesis is on the bilateral relationship between South Africa and Malaysia. The thesis appropriates ‘critical theory,’ and as a flexible theoretical tool, and, as an open-ended, loose frame in order to give voice to the marginalized and voiceless from the South. The thesis thus looks at the politico-economic ties that have been developed and brings into view the socio-cultural relations that had been established between the peoples of the two sovereign nation-states during the apartheid and post-apartheid eras respectively. The basic purpose of this study was fivefold: (a) to contribute to the extant literature that concentrates on South Africa’s relations with Malaysia, (b) to examine the relationship at political and economic ties in some detail, (c) to demonstrate that apart from the afore-mentioned bonds IR specialists should also take into account the socio-cultural dimensions of international relations, (d) to bring to light the nation-state’s limitations when discussing the role of non-state actors and considering the contributions of other factors such as globalization, and (e) to stimulate further research on bilateral and multilateral relations in the South – particularly between South Africa and other states in Asia and Latin America - that would assist to better understand the past, present and perhaps the future.
