- Description: The development of standards for education and training is regarded as a very important activity by many countries. Any country that sets standards for education and training is trying to define its training system and avoid duplication of training by providers who do not see eye to eye. National standards are public documents accessible to anyone interested in education and training. Namibia introduced standards setting as a core activity of administering the National Qualifications Framework in 1996 after the passing of the Namibia Qualifications Act by parliament. This research attempts to gain an understanding of how the process of developing standards for the Life Assurance Sector in Namibia was managed by focusing on the experiences of three persons who took part in the process of developing the said standards. The case study approach enabled me to gain considerable insight into management issues that may have influenced the process of developing these specific standards. The findings illuminate the management and leadership issues which characterised the process for the LA Industry. Several management issues emerge as key elements in the process. These include: A strong emphasis on transformational leadership through clear vision crafting; empowerment through emancipatory thinking; OD features such as problem solving and effective communication; the importance of organisational structure; the concept of a learning organisation and benchmarking as well as collegiality. This research explores the relationship between management thinking generally, and the management of the standards development process in particular.

- Description: Streptomyces fradiae is a bacterium which has been previously found to produce extracellular enzymes which are capable of wool degradation and skin depilation. Streptomyces fradiae 3739 and other strains of Streptomyces were found in this study to be able to degrade a keratin source (wool) to a considerable degree. However according to the evidence of SEM micrographs presented here the highly keratinised spindle cells of the paracortex are fairly resistant to protease attack, and it is the cementation material which binds these cells together which is initially degraded by the proteases. A large degree of correlation was found with the strains of Streptomyces studied, between the ability of the individual strains to degrade wool and the ability of their extracellular proteases to reduce the depilation load of sheepskins. With further analysis S. fradiae 3739 was found to produce at least one amylase and four or more proteases. The proteases as a group had maximal proteolytic activity in the 8.0-9.0 pH unit range, and were considerably thermostabilised by the inclusion of calcium ions into the reaction solution. The protease group was found to cause depilation of merino sheepskins. For comparative purposes a protease produced by a strain of Proteus vulgaris isolated from a staling hide with hair slip (natural depilation) was studied. The protease activity was maximal in the alkaline region between 8.0-9.0 pH units. Tbe protease appeared to be a single enzyme with a molecular mass of approximately 44 000 daltons. The protease was maximally active at 40°C, although it was only thermostable to 30°C. The enzyme was ineffectual as a depilant except when the skin was pre-treated with a strong alkali, preferably including sodium sulphite in the protease preparation. One of the most important differences between the extracellular proteases of S. fradiae and P. vulgaris was that the former were greater in variety and caused a greater decrease in the depilation load of sheepskins than the latter. Further research with mixtures of commercial proteases provided evidence that a synergistic depilatory effect occurs when proteases of complementary bond specificities are used in conjunction in enzymic depilatory preparations. Some form of strong alkali treatment of skins was found to be necessary to produce leather of the prerequisite quality when the skin was depilated by proteases, otherwise the skin was found to be depleted and stiff. Calcium hydroxide alone was found to be inadequate for this task, probably owing to the fact that it is less alkaline than the lime-sulphide mixture. The calcium hydroxide (lime) must therefore be used in conjunction with sodium hydroxide (which makes the solution as alkaline as that of the lime-sulphide solution) to produce leather comparable to that produced by the lime sulphide treatment. A combination of the information provided by the present research and that gleaned from the relevent literature allows for the construction of a model to represent the possible mechanism of enzymic depilation of skins, in which depilation is caused by the disruption of the basement membrane at the dermal-epidermal junction by the degradation of its constituent molecular components by general proteases, resulting in the removal of the epidermis and its associated wool or hair

- Description: Information is a critical asset in any organisation and its management, including the associated technological channels, requires the attention of decision-makers to ensure that information assets are utilised for the intended purposes. Therefore, decision-makers need to have appropriate governance oversight on technology that produces information and information itself. Over the years, the governance of ICT has been adopted in the public sector given the fact that state funding received from tax collections is utilised to invest in IT solutions with the intention of expediting service delivery and increase productivity. The purpose of this treatise was to identify the root causes of why the department is not implementing Corporate Governance of ICT successfully despite the fact that most good controls do exist. The research revealed that there is insufficient budget to implement ICT projects coupled with inadequate ICT staff to implement ICT strategy. Furthermore, it cited a lack of ICT governance skills with ICT Strategic Committee members who are tasked with pioneering ICT governance. This weakness relates directly to other identified weaknesses such as end-user resistance to adopt ICT projects and a lack of project management function in the department.

- Description: A growing number of primary schools are acquiring computers, mainly through parent funding. The study concerns the promotion of computer use across the curriculum in primary schools. Teachers need to be trained in the use of computers as a teaching aid in different subjects. A study comparing two periods of training was undertaken. Two model C primary schools, administered by the Department of Education and Culture, with similar profiles of educational computer use, were selected for the purpose. A training course consisting of five sections, where the use of the word processor, spreadsheet and database, both as personal tools and as teaching aids were introduced, was offered. Care was taken to select topics from current syllabi and to demonstrate how these topics could be presented and enhanced by using the computer. The training was presented at school A over a period of 8 months and at school B over a period of 5 weeks. The supporting material and contents of the course were the same for both groups. A comparison between the effectiveness of the two training regimes was made. The researcher's initial perceptions of the teachers' initial low level of computer literacy were confirmed by a questionnaire, responded to by each participant. It would seem that the shorter raining period was more effective in raising the level of computer literacy and that if the training period was longer, the contact time should be increased to maintain support. Neither training period resulted in a significant increase in computer use, either as a personal tool or as a teaching aid. The failure to do so may be ascribed to a number of influences, one of which is the teaching style of individual teachers. Changing the teaching style of an experienced teacher takes time and more effort than was available for either training period.

- Description: The measurement of economic performance and social development has become increasingly important as societies have evolved and become more complex. At present nations do not only seek to improve economic performance but are also compelled to improve social development through improvements in socially and environmentally sustainable initiatives. Traditional measures such as Gross Domestic Product (GDP) which is derived from United Nations’ System of National Accounts (SNA) have been criticised given the inability to adequately account for these social and environmental aspects of social development. Given these perceived deficiencies in the conventional measures, several alternative objective measures have been proposed in an attempt to address these shortcomings. Therefore the primary aim of this study is to analyse, via a literature survey, these alternative objective measures of economic performance and social development. The alternative measures that constitute the survey are the Index of Sustainable Economic Welfare (ISEW), the Genuine Savings (GS), and the United Nations’ Human Development Index (HDI). Upon the completion of the literature survey, sustainable development theory is used to evaluate the extent to which the National Accounts and the alternative objective measures are consistent with Hicksian and Fisherian definitions of income and capital, which embody the concepts of sustainability and sustainable development. The evaluation reveals that the National Accounts neither conform to the Hicksian nor the Fisherian definitions of income, thus could not be viewed as a measure of sustainable income. It is found that the ISEW is consistent with the Fisherian definition of income and is also a partial indicator of sustainable development. The evaluation of the GS measure reveals that it is consistent with the Hicksian definition but not the Fisherian definition. In terms of overall sustainability, it is argued that GS is a partial measure of weak sustainability. The HDI is similar to the National Accounts, in that it is neither consistent with the Hicksian nor the Fisherian definitions of income and is also not a measure of sustainability. In summary, the study demonstrates that despite GDP's shortcomings as a measure of economic performance and social development, currently, there is no alternative approach which simultaneously addresses every flaw in GDP. However, all the alternatives yield a much better approximation of social development than GDP.

The study used the qualitative design. Data was collected using in-depth interviews in which twenty individual participants took part. The results indicate that the challenges of SAP child protection unit in providing services to vulnerable children in Alice, Eastern Cape Province are mainly financial based, emotionally stressful, labour related, and can be caused by parental oversight, legal constraints that begets lack of trust and also policing illegal child immigrants. These factors make the police child protection unit’s work challenging thereby hampering its effectiveness. It has therefore been recommended that the police child protection unit should be given the support due to them so as to make service delivery to vulnerable children in Alice effective. Also it has been recommended that children be educated that the police are there to enforce the law, assist and not to harm them.

- Description: This study evaluated how the communication of the new performance management system by the City of Windhoek influenced the beliefs of its employees and consequently to determine the effects of the communication process on the degree to which buy-in and readiness is created. Armenakis, Harris and Field's (1999) five element model of examining the change recipient's beliefs, namely, discrepancy, appropriateness, principal support, efficacy, and valence was used as a framework for this study. These beliefs play a major role in affecting behaviours of the change recipients (employees) toward the implementation of a new change initiative in an organisation. Discrepancy involves assessing if employees believe that a need for change does really exist in the organization. Appropriateness seeks to find out from the change recipients whether the performance management system being introduced in the organization is an appropriate reaction to the need and the vision of the organisation. Principal support describes the support from change agents and opinion leaders for the organizational change. Efficacy refers to a belief in one's capabilities to organize and execute the courses of action required to produce given attainments. Valence refers to the intrinsic and extrinsic attractiveness (from the change recipient's perspective) associated with the perceived outcome of the change. Literature on organizational change, organizational communication and change implementation were used, to gain and highlight insights regarding the role of change communication during change implementation, and to provide the conceptual framework for the research design and analysis. A single case study research method was used under a mixed research paradigm. The study used a survey questionnaire that was sent to 711 employees; a sufficient and representative 202 questionnaires were returned from all levels of the organization, yielding a response rate of 22.4%. In addition, three focus group interviews of a representative cross section of staff were conducted as also document analysis to collect data for the study. The summative average percentages of levels of agreements and disagreements of the respondents for each of the five change recipient's beliefs indicate a fairly high degree of agreement (buy-in) and considerably low degree of disagreement (resistance) among the respondents to nearly all five change recipient's beliefs. Discrepancy received the highest degree of agreement (buy-in) 84%; efficacy received 73%, appropriateness 66% and valence 59% whereas principal support scored the lowest degree of agreement of about 40% of the respondents. Despite the high degree of agreement (buy-in) for these elements, there was also a notable number of the respondents who neither agreed nor disagreed to some of the five change recipient's beliefs. In particular, principal support had 38%, valence had 28%, and appropriateness had 22% who neither agreed nor disagreed. The degree of disagreement (resistance) is relatively low in almost all five change recipient‟s beliefs except for principal support which indicated slightly higher levels of disagreement (19%). The results of the study indicate that the communication methods e.g., the road show, leaflets and brochures, discussions and training sessions used during the pre-implementation phase of the new performance management system influenced the change recipient‟s beliefs on the discrepancy for the new performance management system. The evidence is that these communication methods and actions helped to create a sense of urgency and the need to implement a new performance management system among employees. The new performance management system was also believed to be appropriate and its appropriateness was justified through the use of various communication methods which provided detailed explanations on how the new performance management system was different to the earlier performance appraisal system. Notwithstanding the belief in the appropriateness of the new performance management system, the study found that the absence of such a performance management system over a long period of time had cultivated a hidden but unifying shared set of values, beliefs and assumptions among employees that seem not to fit or be suitable to the demands of the new performance management system and the current challenges facing the organization. The employees themselves noted this discrepancy. Hence, they argued, there is a need to bring about new culture with new sets of values, beliefs and assumptions that will better suit and support the current demands facing the organisation and its members. The study found that although employees significantly believe that they have high levels of personal self-efficacy, the change message that was communicated to them did not in itself appear to help to create and further develop this employee self-efficacy. The change message mainly focussed on the need for training, and the design of job descriptions and technical aspects of the performance management system. The study revealed that the employees' belief in principal support of the new performance management system was that principal support was seen as less than sufficient or not as evident as they would have liked. Employees remarked that principal support was only conveyed during the initial stage of communication, thereafter, principal support from senior management was seen to have declined throughout the pre-implementation phase. Nonetheless, immediate supervisors and managers were believed to more supportive than senior management. The literature points to a lack of belief in principal support as an important cause of a loss momentum in change initiatives, which in turn may result in cynicism and greater resistance, especially by those who have vested interest in maintaining the status quo. Valence refers to the intrinsic and extrinsic attractiveness (from the change recipient's perspective) associated with the perceived outcome of the change. The results show that respondents have mixed beliefs about the personal benefits associated with the new performance management system. Thus, 63% of the respondents believe that it will benefit them, 75% believe that it will increase their self fulfilment, 68% believe that it will increase their feeling of accomplishment, 45% believe that their fringe benefit will remain the same after it is implemented, and 58% believe that they could earn high performance return. However, the result also shows that there are still many respondents who neither agree nor disagree to the presence of personal valance with regard to the new performance managements system. This study established that the use of various communication methods persuaded the majority of the City of Windhoek employees to view the new performance management system overall in a favourable light. However, interviewees criticised the communications process on the grounds that most of these methods were only used once and were not repeated, as they would have liked. Lessons on this item from other change studies are that when communicating new change initiatives, change agents should use different methods of communication and as many times as possible to influence the belief of employees. This report is structured as follows: Section 1 provides an abstract and introduction to the study. Section 1.2 presents a brief review of core theories and recent empirical studies relevant to the research problem. Section 1.3 provides a description of the research method followed in addressing aim and objectives of this study. Section 1.4 presents the results of the evaluation report and section 1.5 discusses the findings and make conclusive recommendations. Section 2 of this study complements subsection section 1.2 (in section 1) with a more detailed review of the literature on organizational change, organizational communication and change implementation. This more detailed review was conducted before the field work and write up of Section 1. The literature incorporated into Section 1 was distilled from this more detailed review. Similarly, Section 3 of this study complement subsection 1.3 (of section 1) with an extended description of the research design and research procedure followed in the study.

These beliefs play a major role in affecting behaviours of the change recipients (employees) toward the implementation of a new change initiative in an organisation. Discrepancy involves assessing if employees believe that a need for change does really exist in the organization. Appropriateness seeks to find out from the change recipients whether the performance management system being introduced in the organization is an appropriate reaction to the need and the vision of the organisation. Principal support describes the support from change agents and opinion leaders for the organizational change. Efficacy refers to a belief in one's capabilities to organize and execute the courses of action required to produce given attainments. Valence refers to the intrinsic and extrinsic attractiveness (from the change recipient's perspective) associated with the perceived outcome of the change. Literature on organizational change, organizational communication and change implementation were used, to gain and highlight insights regarding the role of change communication during change implementation, and to provide the conceptual framework for the research design and analysis. A single case study research method was used under a mixed research paradigm. The study used a survey questionnaire that was sent to 711 employees; a sufficient and representative 202 questionnaires were returned from all levels of the organization, yielding a response rate of 22.4%. In addition, three focus group interviews of a representative cross section of staff were conducted as also document analysis to collect data for the study. The summative average percentages of levels of agreements and disagreements of the respondents for each of the five change recipient's beliefs indicate a fairly high degree of agreement (buy-in) and considerably low degree of disagreement (resistance) among the respondents to nearly all five change recipient's beliefs. Discrepancy received the highest degree of agreement (buy-in) 84%; efficacy received 73%, appropriateness 66% and valence 59% whereas principal support scored the lowest degree of agreement of about 40% of the respondents. Despite the high degree of agreement (buy-in) for these elements, there was also a notable number of the respondents who neither agreed nor disagreed to some of the five change recipient's beliefs. In particular, principal support had 38%, valence had 28%, and appropriateness had 22% who neither agreed nor disagreed. The degree of disagreement (resistance) is relatively low in almost all five change recipient‟s beliefs except for principal support which indicated slightly higher levels of disagreement (19%). The results of the study indicate that the communication methods e.g., the road show, leaflets and brochures, discussions and training sessions used during the pre-implementation phase of the new performance management system influenced the change recipient‟s beliefs on the discrepancy for the new performance management system. The evidence is that these communication methods and actions helped to create a sense of urgency and the need to implement a new performance management system among employees. The new performance management system was also believed to be appropriate and its appropriateness was justified through the use of various communication methods which provided detailed explanations on how the new performance management system was different to the earlier performance appraisal system. Notwithstanding the belief in the appropriateness of the new performance management system, the study found that the absence of such a performance management system over a long period of time had cultivated a hidden but unifying shared set of values, beliefs and assumptions among employees that seem not to fit or be suitable to the demands of the new performance management system and the current challenges facing the organization. The employees themselves noted this discrepancy. Hence, they argued, there is a need to bring about new culture with new sets of values, beliefs and assumptions that will better suit and support the current demands facing the organisation and its members. The study found that although employees significantly believe that they have high levels of personal self-efficacy, the change message that was communicated to them did not in itself appear to help to create and further develop this employee self-efficacy. The change message mainly focussed on the need for training, and the design of job descriptions and technical aspects of the performance management system. The study revealed that the employees' belief in principal support of the new performance management system was that principal support was seen as less than sufficient or not as evident as they would have liked. Employees remarked that principal support was only conveyed during the initial stage of communication, thereafter, principal support from senior management was seen to have declined throughout the pre-implementation phase. Nonetheless, immediate supervisors and managers were believed to more supportive than senior management. The literature points to a lack of belief in principal support as an important cause of a loss momentum in change initiatives, which in turn may result in cynicism and greater resistance, especially by those who have vested interest in maintaining the status quo. Valence refers to the intrinsic and extrinsic attractiveness (from the change recipient's perspective) associated with the perceived outcome of the change. The results show that respondents have mixed beliefs about the personal benefits associated with the new performance management system. Thus, 63% of the respondents believe that it will benefit them, 75% believe that it will increase their self fulfilment, 68% believe that it will increase their feeling of accomplishment, 45% believe that their fringe benefit will remain the same after it is implemented, and 58% believe that they could earn high performance return. However, the result also shows that there are still many respondents who neither agree nor disagree to the presence of personal valance with regard to the new performance managements system. This study established that the use of various communication methods persuaded the majority of the City of Windhoek employees to view the new performance management system overall in a favourable light. However, interviewees criticised the communications process on the grounds that most of these methods were only used once and were not repeated, as they would have liked. Lessons on this item from other change studies are that when communicating new change initiatives, change agents should use different methods of communication and as many times as possible to influence the belief of employees. This report is structured as follows: Section 1 provides an abstract and introduction to the study. Section 1.2 presents a brief review of core theories and recent empirical studies relevant to the research problem. Section 1.3 provides a description of the research method followed in addressing aim and objectives of this study. Section 1.4 presents the results of the evaluation report and section 1.5 discusses the findings and make conclusive recommendations. Section 2 of this study complements subsection section 1.2 (in section 1) with a more detailed review of the literature on organizational change, organizational communication and change implementation. This more detailed review was conducted before the field work and write up of Section 1. The literature incorporated into Section 1 was distilled from this more detailed review. Similarly, Section 3 of this study complement subsection 1.3 (of section 1) with an extended description of the research design and research procedure followed in the study.

- Description: The management of Nigeria high schools are noted for administrative practices in the management of their schools; hence the term administration is commonly used in their daily operations. This fact on ‘administration’ was emphasised by the Nigerian government in the National Policy on Education (Nigeria, 1981, p. 21). Therefor as a researcher from Nigeria, my rationale for embarking on this research study was to find out to what extent a public high school in Nigeria was still operating in a hierarchical, individualistic, authoritarian style of leadership or whether it has started embracing contemporary approaches such as distributed leadership. The main goal of this study was to explore leadership practices in the case study school with the main focus on how different people relate to each other in the various leadership practices of the school, such as staff and briefing meetings of the school. In addition, my research questions aimed at exploring the respondents’ perceptions of leadership and factors enabling or constraining the distribution of leadership in the school. The study is located within the interpretive paradigm. As a researcher in a wheelchair studying in South Africa I needed to find alternative ways of accessing the research site and gathering data. I was able to use electronic communication for the collection of my data. I used four different tools of data collection methods namely document analysis, observation, questionnaire and stimulated recall interviews. Findings from the study indicated that there was limited evidence of contemporary leadership approaches in the case study school. The school was still operating traditional leadership, while school activities were dominated by a hierarchical chain of command. What emerged from the leadership practices of the school could be termed authorised distributed leadership which was under the command of the school principal. Data also indicated that there were some forms of restricted teacher leadership in the management and administration of the school. In addition, findings revealed that the case study school was very good at the management and administrative functions. The school was very effective and efficient in the controlling and management of both human and material resources. Lastly, findings from the case study school indicated some enabling factors to the distribution of leadership in the case study school which include a culture of respect and cordial relations among the SMT and the teachers, Prominent among constraining factors to the distribution of leadership in the case study school were: cultural orientation of the people where the case school was located, exclusionary religious practices by the principal of the school and the inhibiting role played by the Ministry of Education. Finally, based on these findings, recommendations were made both for practice and for future research.

- Description: People who have been diagnosed HIV positive often experience distress and anxiety due to uncertainties pertaining to the implications of an HIV positive status. Research has shown that support groups have always been a way for people to cope with the distress and stressful circumstances associated with health conditions such as HIV. This research investigated the role of face to face support groups in the lives of those living with HIV. The primary focus of this research project is to provide an in-depth exploration of HIV positive individuals‟ experiences of being in a support group. The study aims to explore the positive and negative experiences of being in an HIV support group and aims to gain an understanding of the role support plays in the lives of those living with HIV. A qualitative research design was used to explore the above mentioned aim. Semi-structured interviews were conducted with five individuals, (three women and two men) who had experienced HIV support groups. The interviews were transcribed and then analysed according to the principles of interpretative phenomenological analysis (IPA). The findings of this study revealed five super-ordinate themes, which revealed not only the positive and negative experiences of being in a support group, but also the challenges that the participants‟ experienced before joining the group. Getting a sense of the participants‟ experience before joining the group allowed the researcher to get a better understanding of how useful or not the support group has been in helping them deal with the challenges of living with HIV. The themes included: „struggling to survive after diagnosis‟, „struggling to cope: adopting negative coping skills‟, „experiencing a turning-point: a will to survive‟, „attending support group: a sweet experience‟ and lastly, „attending support groups: a bitter experience‟. Findings suggest that for these participants, the advantages outweighed the disadvantages of being in a support group. Therefore this study suggests that face to face support groups are a viable and even necessary option for support. These findings support previous research and literature in regards to the importance of social support in the form of support groups in effectively assisting HIV positive people in their journey to adjust to the consequence of living with HIV.

- Description: Informed by the political economy framework and the public service role of media in democracy, the main objective of the study was to use in-depth semi-structured interviews to understand news-workers’ professional journalistic identities in relation to their status as government employees and the understanding of their public service role as outlined in the paper’s mission statement. The main interest was to understand the complexity of negotiating these role identities. Through reference to the theories of journalism professionalism, the study highlighted the extent to which news-workers in the small newsroom of Lentsoe la Basotho/Lesotho Today see themselves as public service journalists in a democratic country. The interest was borne partly out of the views of the paper’s critics who see it as not serving the public but rather promoting the activities and policies of the government of the day, thus falling short of its democratic role. The contention of the study was that as a public service newspaper, the paper should have news-workers who do impartial journalism and reflect the public’s right to know in their reporting. The findings of the study suggests that news-workers at Lentsoe la Basotho/Lesotho Today continuously have to strive to negotiate the potential conflict between being a professional and working for a government-controlled newspaper. While they sometimes lay claim to being journalists, the reality is that in their political coverage they end up adopting the role of government mouthpieces.

- Description: For the past thirty years, leadership theories have focused on the importance of the individual within the school organisation. The shared assumptions and beliefs of the individuals working in the same organisation shape the school’s organisational culture, and organisational culture is a salient factor which should be considered when understanding educational leadership. The focus of my study is to explore the relationship between organisational culture and leadership. In the same context, new approaches to the study of leadership have explored the issue of gender in leadership. Female leadership studies - the second focus of this study - seek not only to restore the place of the individual but also argue a place for women in educational leadership. Based in the interpretive paradigm, this is a case study of a Catholic all-girl secondary school called the Loreto Convent School of Pretoria. Historically, the Loreto schools have aimed at promoting and empowering girls’ education and female leadership. It was therefore an appropriate site in which to explore organisational culture and its relationship with leadership, particularly female leadership. I purposefully chose three of the school’s female leaders - the school’s principal, the High school Head of Department and the High school head girl - focusing on their perceptions and experiences of their leadership and the school’s culture. My research findings show that an understanding of the relationship between organisational culture and leadership cannot be complete without acknowledging the importance of the leader as an individual, with his/her personal background and values, taking into account gender as well as the multiple roles that the individual has in society. Furthermore, the ‘humane’ characteristic of educational leadership leads to an understanding that the leader is often confronted with conflicting situations where he/she is caught between personal/organisational values and the need to achieve the task. Finally, my findings show that contemporary leaders are now called upon to work and participate in the promotion of social justice in order to fight against society’s socio-economic inequality and improve the quality of education and life.

- Description: Indigenous forests along the Wild Coast of the Eastern Cape Province have experienced both degradation and deforestation over the past decades. In early 2000, steps were taken to rehabilitate some of the degraded areas. Nevertheless, there is no monitoring mechanism in place, so little is known about the extent of degradation and impact of the rehabilitation efforts. The present study assesses the extent to which deforestation and degradation of the indigenous forests have occurred, and evaluates rehabilitation efforts in the study area around Port Saint John’s. Forest degradation was defined as the decrease in forest cover density while deforestation was defined as an increase in the trend of light forests and/ or a decrease in dense forests. The details for this study were obtained from multi – temporal remotely sensed data for a period between 1982 and 2013 (31 years). Multi-temporal Landsat satellite imagery for 1982, 1986, 1989, 2002, 2009 and 2013 was acquired and analysed. On the basis of prior knowledge of the area, the supervised classification approach was used. The Maximum likelihood supervised classification technique was used to extract information from satellite data. The classified images were filtered using a majority filtering procedure to reduce noise. Google Earth (Astrium) ancillary images were used to refine the classification based on expert rules. The derived changes in the degraded and rehabilitated areas were further validated through field visits. The overall image classification accuracy generated from Landsat image data ranged from 80% to 90%. It was noted that the area of dense forest almost doubled between 1986 and 1989, coinciding with a 59% decrease in the light forest. Subsequently, dense forests increased by 14,820 ha while light forests decreased by 16,690 ha between 1989 and 2002. The subsequent reduction in light forest coverage is explained by the establishment of the Participatory Forest Management (PFMA) approach by Department of Water Affairs and Forestry (DWAF) which reversed the degradation trend. However, specific degradation hotspots were identified, particularly where new settlements have been established. The emergence of the non-vegetated area increased gradually from 7% in 1986 to 23.4% in 2013. Notably, dense forest was observed to have experienced higher rates of forest degradation and deforestation than the light forest. The highest number patches were 4 recorded between 2002 and 1998, followed by between 2010 and 2013 and lastly 1986. Based on spatial connectedness of patches, the year 1986 had the highest landscape connectedness of forest vegetation (CONAT = 35.3) followed by 2002 and 1996 while the year 2010 and 2013 had the lowest landscape contiguity. Over the study period, the distribution of patches clearly shows that forest degradation and deforestation rates were lower in the years 1986, 1998 and tremendously increased in the later period of between 2010 and 2013. However, as a result of rehabilitation efforts, dense forest was seen to steadily gain more land than light forest. Finer details of degradation trends could not be easily picked from the images used in the study, given their spatial resolution limitations. That notwithstanding, the trends identified are good for overview decisions. The study has also established that de-agraianisation, forest restoration and rehabilitation greatly contributed to increased forest cover. Therefore, with more use of GIS by forest managers, and imagery of the high resolution being readily available, forests will in future be easily monitored using remote sensing.

RNA 1, the larger of the two RNA molecules, with a MW of 1,15 x 10⁶ and the smaller RNA 2 with a MW of 0,46 x 10⁶, are both packaged in the same virus particle. The two RNA molecules are translated separately, with RNA 1 coding for protein A of MW 105 x 10³ and RNA 2 coding for protein α of MW 47 x 10³. Protein α is the major capsid protein precursor, which during in vivo maturation is cleaved to form the coat protein β of MW 43 x 10³, and protein γ of MW 5 x 10³. Cell-free translation of BBV (strain W17) mRNA was carried out in rabbit reticulocyte lysates. Protein α was detectable between 0 and 30 minutes after RNA addition. A protein 'β', which was found to co-electrophorese on polyacrylamide gels with authentic β and which was immunoprecipitated by anti-BBV antiserum, was detectable after 30 minutes. Results of this work show that the formation of 'β' could be prevented by the addition of RNase to the lysate, indicating that intact RNA is necessary for α to β cleavage. Arresting protein synthesis by the addition of cycloheximide to the lysate mix did not inhibit the cleavage. The formation of β could also be prevented by cooling the lysate mix to 1°C. Cleavage of α to β still occurred when RNA 2, without the presence of RNA 1, was translated. Therefore the cleavage is not dependent on a translation product of RNA 1. Sedimentation of lysate on sucrose density gradients showed that α to β cleavage was not accompanied by assembly of BBV RNA and protein lnto a viral substructure as has been shown to occur with some viruses, for example certain picornaviruses. Serial dilution of lysate containing α showed that the level of β decreased with increasing dilution, indicating that the cleavage is not mediated by autocatalysis, but by some other unknown factor. Although much work has been carried out on black beetle virus, no work has been published to date concerning α to β cleavage as an indication of assembly in rabbit reticulocyte lysates. Results of these cell-free translation experiments thus indicate that BBV coat protein precursor α, in association with its messenger RNA 2, undergoes a maturation cleavage in the lysate to produce BBV coat protein β. In addition, this cleavage seems to occur without assembly into any intermediate viral structure

- Description: With the continued miniaturization of technology and the incorporation of Moore’s law, smartphones are more powerful. These mobile devices contain technologies that add other functionalities to them. Technologies such as sensors constantly provide information to the device. The constant stream of information from these sensors often leads to information overload of relevant and irrelevant information. To work towards solving this problem context-aware computing was introduced. Our major concern is that context information in context aware computing is not completely being utilized. The aggregation of context information could unlock more possibilities. This research seeks to aggregate the context of multiple devices such that, through analysis, some emergent behaviour can be observed. In this research context information from the sensors of devices is collected using an Android application and a central Server. The context information is used for pattern analysis. A pattern analysis algorithm is designed and used to observe patterns throughout the data set. It shows patterns that are similar within the dataset. In the case that the pattern observed has no similar pattern or few similar patterns this behaviour can be stated as emergent in the dataset. Further study of this emergent behaviour can be performed were a classifier can be used to give the exact activities that were being performed at that time. The research found this was possible and has many uses. One of these is in disaster prevention were the behaviour of a group of individuals may be monitored to observe any random changes such as masses running at the same time. This could be used as a first warning to natural disasters.

- Description: South Africa is characterised by high levels of HIV infections and unwanted pregnancies, despite the vast amount of interventions aimed at combatting this issue. It becomes important to explore why these interventions are not actively achieving what they aim to. A major cause for concern is the increase in risky sexual behaviour in the adolescence and young adult (15-24 year) age group. In various cultures, women’s socialization has a direct impact on their ability to prioritize their sexual health. Steeped in patriarchal ideology, many South African cultures prioritise the power of masculinity over and above the femxle experience. Improved partner communication leads to decreased risky sexual behaviour, but it becomes tricky when the relationship is characterized by a gender power imbalance. This study is aimed at understanding South African femxle sexual health by focussing on 1) the extent to which the overarching traditional beliefs about femininity is related to their sexual self-efficacy. Furthermore, it is aimed at 2) the extent to which they engage in sexual activity and behaviour that would protect them from STIs and unwanted pregnancies. Research design is quantitative and include an online survey for femxle students between the ages of 18 and 24, enrolled at the Nelson Mandela University, South Africa. The data was analysed statistically, where after the research findings will be interpreted from the perspective of Feminist Psychological Theory.

- Description: Fifty pre-pubescent Xhosa-speaking children from two primary schools within the township of Rini, Grahamstown, were selected in this study to determine the effects, if any, of an enriched physical activity programme. Subjects were divided into experimental and control groups with only the experimental group physically participating in the enrichment programme. Selected anthropometric, physiological and motor performance tests were administered on both groups, before and after the programme, to monitor the effect of the enrichment programme on growth, cardiovascular efficiency and physical performance. Somatotype ratings showed no change after the training programme. However body composition showed greater gains in fat mass in the control group and marked drops in fat mass and increases in lean body mass in the experimental group. Longer running distances, higher predicted VO2 max mean values and improved recovery heart rate (HR) as well as larger gains in relative power, absolute power and velocity were experienced by individuals who participated in the training programme. The performance of the experimental group in the two motor performance tests out-weighed by far the performance of the control group as a result of the additional programme. The enrichment programme not only produced a positive effect on body composition but also improved aerobic and anaerobic efficiency. Improvements in both motor performance tests favoured the experimental group.

- Description: The textile industry in South Africa is a significant contributor to the chemical load that public wastewater treatment plants have to process, and the discharge of toxic substances, especially to the aquatic environment. In order to address this issue at factory level, the processes at a textile plant, JMV Textiles were chosen for investigation into the possibilities of minimization of discharges of harmful substances into the environment. The study followed the principles of cleaner production, and the processes that were investigated and revised were: The conventional peroxide bleaching process employed a peroxide stabilizer that did not biodegrade easily. The bleaching process was changed, so that the prevailing conditions in the fabric and dyebath facilitated bleaching without the addition of peroxide stabilizer, and also reduced the alkali and energy requirements. Polyester‐viscose fabric was pretreated by bleaching with hydrogen peroxide, which seemed to be unnecessarily rigorous, because polyester and viscose, unlike natural fibres, are relatively clean and have good whiteness in comparison with natural fibres. The proposed alternate pretreatment was a scour with detergent and alkali. The pretreatment for all polyester‐cotton fabrics was also a hydrogen peroxide bleach. Due to the ability of medium and dark shades to mask the natural tint of cotton fibres, a simpler alternate pretreatment, consisting of an alkaline scour with sequestering agent, was trialled. An unacceptable proportion of the dyeings on polyester was rejected for dye‐stains and dye‐marks. A possible solution exploited the properties of using the finishing auxiliary chemical to alleviate dye‐stains and dye‐marks during the dyeing stage, instead of using the chemical after dyeing. The highly toxic carrier that was used to facilitate level dyeing of polyester fibres that had unacceptable variation in their dyeing properties, was replaced by a less toxic carrier. The formulation for dyeing polyester was simplified to eliminate the auxiliary chemicals that were not essential to the dyeing process. Pale reactive dyed shades on cellulose and polyester‐cellulose were washed off only with hot water instead of detergent. The revised procedures consequential to the study, offered significant environmental benefits by reducing the concentration and volume of effluent produced, substituting a highly toxic carrier with a less toxic one and saving energy and water. Implementation of the suggested changes also offered financial benefits. The management of the factory, however, accepted and implemented some changes, but wanted further investigations for others and a phased approach to the other suggested changes.

- Description: The purpose of the study is to explore and describe challenges experienced by health professionals regarding implementation of the referral system used in Buffalo City Metropolitan Municipality (BCMM) in the Eastern Cape Province. A referral system in health care can be defined as a method whereby a health worker with insufficient skills and less resources in the primary health care setting, who has fewer remedies or options to manage medical conditions, seeks assistance from a more senior practitioner in a tertiary setting with better resources to provide guidance in managing the patient or to take over the management of the patient (Eastern Cape Department of Health, 2007:7). A qualitative descriptive explorative contextual design was used to explore and describe the challenges pertaining to the implementation of a referral system in the public health sector in Buffalo City Metropolitan Municipality (BCMM) in the Eastern Cape. A purposive sampling technique was employed with an inclusion criteria of health care professionals who are doctors, professional nurses, pharmacists and specialists. After obtaining ethical clearance from the respective departments, steps for data collection were implemented. Individual interviews were conducted using an interview guide that was prepared by the researcher. Findings in the study indicate that there are challenges in implementing a referral system in relation to infrastructure, workforce capacity, equipment, transport and drug availability. The participants provided suggestions according to their experiences on what they felt the Department of Health in BCMM could do to strengthen the referral system in place. The researcher then provided recommendations to the Department of Health of BCMM. The health referral system in BCMM needs to be strengthened through provision of adequate infrastructure, improving workforce capacity, and availability of medicines and equipment. A monitoring and evaluation plan must be affected by the Eastern Cape Department of Health. Education and training are needed for the health care workers and the community through their involvement in stakeholder meetings

- Description: This thesis defends an ontological and epistemological account of Michel Foucault's post-structuralist philosophy, to argue that political philosophy needs to take into account the historical and political contingency of subjectivity and discourse. I show that by addressing the historical and political contingency of knowledge, Foucault's work overcomes the flaw of foundational epistemology in political philosophy, which treats true discourse as universal and disinterested. In doing so I hope to have to refuted the mainly positivistic and humanist schools of thought that lay claim to universal and foundationalist notions, by demonstrating the extent to which their misgivings about Foucault's work are informed by and founded upon an unjustified a-historicism. The thesis is composed of three chapters, the first of which deals with an ontology of the subject, the second, with an ontology of social relations, and the last with epistemology. In each chapter I use dialectical analysis to reveal how interests necessarily mediate subjectivity, social relations, and knowledge. The first two chapters defend Foucault's conception of power, by way of an analysis of the relations between Foucault's work and Sartre's existential phenomenology. I show how both Foucault and Sartre successfully address the problem of historicism for political philosophy with their respective conceptions of human freedom. The final chapter defends Foucault's conception of the relations between power and discourse, to show how it overcomes the a-historicism of universal, foundational epistemology. These three chapters demonstrate the importance of accounting for historicism in political philosophy. Claims to universal interest, because knowledge is conditioned by conflicts of interest, often mask political domination. It is important, then, to remember, in political philosophy, that knowledge is evaluative and interested, reflecting historically and politically mediated evaluations. One should be suspicious of ' natural facts' , used to justify actions or beliefs, thereby masking the choices that inform them. I have used the work of Michel Foucault to motivate this claim.
