- Description: Introduction: The macroporous Amberlite XAD resins were coated with LIX-64N and examined for the rate of uptake of copper . XAD-7 was by far the best support and gave a satisfactory rate of uptake up to loadings of 60% (w/w). The specific surface area of XAD-7 was measured by the adsorption of methylene blue from aqueous solution. The area of the wetted resin was five times less than that of the dry resin. LIX-65N was purified and the anti isomer characterised using spectroscopic techniques . The rate of uptake of copper was not improved by use of purified LIX-65N or by addition of LIX-63. XAD-7 coated with LIX-65N was used in columns. Elution curves for copper showed negligible tailing, and rapid separations of copper from iron (111), nickel, cobalt and magnesium by selective absorption were achieved. Copper was concentrated from very dilute solution at a flow rate of 50 ml min -1 ,and a 99% recovery was obtained. The method was applied to the rapid determination of copper in brass and bronze. A series of long-chain hydroxamic acids were synthesised and tested for suitability as stationary phase on XAD-7. Oleohydroxamic acid and naphthenohydroxamic acid were the most promising. The r ate of uptake of copper was reduced by the use of nonylphenol or amyl alcohol as a diluent. The capacities for copper of the hydroxamic acids were less when supported on XAD-7 than when used as liquid ionexchangers. The distribution coefficients of cobalt, nickel, zinc, lead, vanadium, uranium, iron (111) and copper were measured as a function of pH. XAD-7 coated with oleohydroxamic acid was used in columns for the rapid separation of iron (111) from copper and of copper from nickel, cobalt, lead and zinc. Copper was concentrated from very dilute solution at a flow rate of 45 ml min -1 and a 100,8% recovery was obtained. Copper was successfully separated from nickel by selective elution. The elution curves obtained show negligible tailing. The resin loaded with oleohydroxamic acid lost capacity due to chemical instability. Naphthenohydroxamic acid supported on XAD-7 was not suitable for use in columns, because it was physically unstable.

- 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.

- 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.

- Description: The South African Nursing Council requires registered nurses to have the necessary knowledge, skills, attitudes and values which will enable them to render an efficient service (Morolong and Chabeli, 2005:39). The South African Education and training system, through its policy of outcomes- based education and training, has tabled competency as a national priority. In support of this, the South African Nursing Council (SANC) requires that the newly qualified registered nurse possess competency on the core functions of a registered nurse. The health system also demands competent nurse practitioners to ensure quality nursing care. Due to the fact that competency is a national priority and a statutory demand, the research question that guided the study is what are the perceptions of unit managers regarding competencies of newly qualified registered nurses in East London Health Care services. The study was aimed at describing the perceptions of unit managers regarding the competencies of newly qualified registered nurses in order to propose the recommendations to improve the competencies of such newly qualified registered nurses and to provide quality patient care. A quantitative descriptive non experimental design was used to evaluate the perceptions of unit managers regarding competencies of newly qualified registered nurses from a public nursing college. The sampling method of probability convenience sampling was used in this study. Data were collected by means of a questionnaire administered to ninety unit managers and only eighty one unit managers participated in the study. Data were analysed using the Statistical Package for the Social Sciences (SPSS) version 22 software. Statistical methods enabled the researcher to reduce, summarize, organise, manipulate, evaluate, interpret and communicate quantitative data. Data were cleaned and coded and spoilt data were checked. Findings from the software were displayed in graphs or tables. Concerning the eighty one unit managers who participated in the study, age and sex matched respondents were selected according to their availability.The results showed that there is agreement that competence of the nurses affects the image, mission and staff utilisation in their units and/or institutions. There was no dominant opinion on the possible association between competency and environmental, physical and technological factors. There was unanimous agreement that newly qualified nurses need constant supervision and in-service training. There was moderate agreement on the use of acquired knowledge and skills by nurses and there was no dominant opinion about how newly qualified nurses tolerate differences and handle misunderstandings and shortcomings of other professions. In conclusion newly qualified registered nurses need coaching, mentoring, n-service training and constant supervision. Recommendations regarding strategies to be used to improve competencies of newly qualified registered nurses included exit evaluations of community service practitioners, stipulating the competency framework of newly qualified nurses and assessment criteria of competency. Mentoring and coaching of newly qualified registered nurses during community service, monthly or quarterly meetings with the community service candidate in order to identify their challenges were also recommended. Motivation strategies in order to boost their morale so that they can deliver quality patient care. The newly qualified registered nurses should hold meetings with the unit managers regarding the challenges the unit managers face when assessing competencies of newly qualified registered nurses.

- 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: 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

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: 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: This thesis examines the meanings that residents of the township of Hooggenoeg (in Grahamstown, in the Eastern Cape province of South Africa) made of the election coverage in the Grocott’s Mail newspaper during 2011 municipal elections in South Africa. In addition, this study also sought to understand the particular set of ‘normative roles’ played by the paper, both with reference to the well-established body of theory about the normative roles of journalism in a democracy, and in terms of the paper’s own conceptualisation of its role in the functioning of local democracy. Grocott’s Mail, the oldest independent newspaper in South Africa, provided extensive pre-election coverage, which included producing and distributing an unprecedented free edition of the paper. The paper also facilitated a town hall debate in order to encourage residents to vote, and empower them to make a more informed choice about their vote. Three qualitative research methods, namely qualitative content analysis, focus group interviews, and individual interviews were used to examine the relationship between the content provided by the paper and the audience’s process of ‘making sense’ and deriving meaning from the content provided. The study concludes that Grocott’s attempt to encourage democratic culture in Grahamstown, in keeping with the more ‘facilitative’ normative roles that the local media can play, was only partially successful. Much of the election reporting subordinated the voices of the ordinary people, and privileged reporting that focussed narrowly on the voting process, and which foregrounded the views of political parties. Overall this coverage largely failed to resonate with the Grocott’s readers who live in Hooggenoeg (a largely ‘coloured’ area of Grahamstown), whose key concerns in terms of their daily life – such as poverty, unemployment, crime, lack of services – seemed, to them, unaddressed by this election coverage and, consequently, was not as engaging or convincing as the publishers/editors had hoped it would be. It can be also argued that Grocott’s narrow conceptualisation of democracy as entailing only public participation in electoral processes failed to cater for how audiences can be made aware of how they can participate in governance beyond the election period.

- 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.

Cleavage of the precursor coat protein of black beetle virus strain w17 in rabbit reticulocyte lysate

- Description: Black beetle virus (BBV) is a bipartite single-stranded RNA virus belonging to the family Nodaviridae. Its host range has been found to be limited to insects. 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: 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: In the major cities of South Africa, there is a prevalence of originally built commercial buildings that are being converted into residential apartments or other industrial economic spaces. These secondary users refurbish the original structures to accommodate their new specialised requirements and this mostly happens after the buildings have been lying vacant for a long period of time. The study by Y.Long et al. (2011) narrates the changes in land use, identification of driving forces and the mapping of areas that are experiencing intense land use transformation. Properties that were developed for a focused particular use, were found to have been redeveloped within a few years for other functions. Subjects that were included in the sample were selected to meet specific criteria. The stakeholders had to meet the following criteria to be included in the sample: They were registered professionals in the built environment such as: Architecture, Engineering (civil, electrical, mechanical and structural), Quantity Surveying, Town Planning, Construction Management and Estate management The method that was used to collect data was self-completion questionnaire that was given out by electronic mail. After the data was collected, it was organised and analysed. For the analysis of closed-ended questions, an online programme called QuestionPro, was used, data was analysed by using descriptive statistics and frequency tables were drawn and from these, the data was presented in pie diagrams and bar graphs. While it is necessary to expand the horizons of the ever-growing global population, it is imperative that all stakeholders in the building industry work together to find sustainable solutions to residential and industrial development.

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 thesis examines the principles and policies underlying the need for transformation within the Playhouse Dance Company (PDC) in Durban and the actualities of implementing these visions and procedures. It is proposed that artistic structures, ideals and processes cannot remain impervious to the climate of change. Alterations in the political arena demand radical permutations within arts councils and their concept of repertoire, educational programmes and training. Transformation is linked to the problem of identity and it is suggested that the company is in the midst of a journey towards "becoming" rather than "being".

- Description: This thesis examines the principles and policies underlying the need for transformation within the Playhouse Dance Company (PDC) in Durban and the actualities of implementing these visions and procedures. It is proposed that artistic structures, ideals and processes cannot remain impervious to the climate of change. Alterations in the political arena demand radical permutations within arts councils and their concept of repertoire, educational programmes and training. Transformation is linked to the problem of identity and it is suggested that the company is in the midst of a journey towards "becoming" rather than "being".

- 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.

- 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.

The effects of criminalising publication offences on the freedom of the press in Uganda, 1986-2000

- Description: The press in Uganda has come a long way right from the colonial days when newspapers sprang up, mainly from missionary activity, through the eras of Obote 1 (1962 – 1971), Idi Amin (1971 – 1979), Obote 11 (1980 – 1985), Tito Okello (1985 – 1986) and the Museveni administration (1986 – to date). For most of this time, the press in Uganda enjoyed very little or no freedom to do its work. The year 1986 saw the ascendancy to power of the Yoweri Museveni as president after a five-year bush war with promised to restore peace, democracy, the rule of law, economic prosperity and civic rights and freedoms. Several achievements in these areas have been registered since 1986. Newspapers have sprouted and the broadcast industry liberalised to allow private ownership that has seen the proliferation of FM stations. However, the relations between the government and the press remain strained with journalists arrested and/or prosecuted mainly for offences relating to sedition, publication of false news and criminal libel. This study was intended to examine why journalists in Uganda continue to suffer arrests and incarceration when the country has been reported to be moving towards democratisation. The study was also aimed at assessing the impact of arresting journalists and arraigning them before the courts of law in the period under study and what this portends for freedom of the press and democratisation. It is recommended, among others, that journalists in Uganda need more unity of purpose to pursue meaningful media law reform that will de-criminalise publication wrongs. The civil remedies available to people who feel offended by the press are sufficient, if not excessive. The efforts already undertaken by the Eastern Africa Media Institute (EAMI) Uganda Chapter in this direction should be pursued to a logical conclusion.

- 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.
