- Description: This thesis seeks to understand and analyze the livelihood strategies of urban women traders at Magaba in Harare (Zimbabwe) in the context of the contemporary economic and political crisis. The crisis emerged in the 1990s with the introduction of a structural adjustment programme and deepened further with the fast track land reform programme initiated by the Zimbabwean government in the year 2000. The crisis has involved a down-sizing of the Zimbabwean economy and a massive rise in the rate of unemployment in the formal economy. Consequently urban life became increasingly unbearable for poor blacks and informal economic activities blossomed and started to make a significant contribution to household income and livelihoods. The role of women in the informal economy was particularly pronounced. Theoretically, the thesis is underpinned by the sustainable livelihoods framework. In examining the vulnerability context of the Magaba women traders and the institutional interventions which complicate the lives and livelihoods of these traders, I identify and unpack their diverse livelihood activities and strategies and the resources (or assets) they deploy in constructing urban livelihoods. Though their livelihood portfolios complement any earnings from formal employment by household members and though they contribute to their household’s sustenance, there are a number of daily challenges which they face in their trading activities and which they seek to counteract through a range of often ingenious coping mechanisms. The thesis is important for a number of reasons. It fills an important empirical gap in the study of Magaba market specifically, it brings to the fore the gendered character of the informal trading activities in urban Zimbabwe, and it deploys the livelihoods framework in a manner which is sensitive to both structure and agency.

- Description: This study was primarily carried out in order to assess the sexual risk behaviours of people living with mental illnesses as well as their vulnerability to HIV infection. It sets out the basic realities of the interaction between mental illness and HIV/AIDS and its impact on individuals and communities. This study explores the implications for health policy and practice, and suggests how to provide better support and assistance in the empowerment of people living with mental illness as far as HIV and AIDS is concerned, including community support. It was also the aim of this study to look into the factors that expose this group of people to HIV infection as well as to understand the link between HIV/AIDS and mental illness. It also tested the inclusion of people with mental disabilities in HIV and AIDS prevention and education programmes. The research was conducted on the basis of a qualitative research design. A semi-structured interview schedule was used in broad based interviews to gather information from caregivers or guardians of people with mental disabilities as well as the professionals in the mental health sector. The results of the research revealed that people who are living with mental illnesses are a vulnerable group as regards HIV infection. It also conveys that this group of people presents with sexual risk behaviours, which increase their vulnerability to HIV and AIDS. In addition, there are many barriers against the inclusion of this group of people in HIV and AIDS prevention and education programmes and, as a result, they are often excluded from participating in such programmes. Importantly, the findings of this study acknowledge that there is a two-fold relationship between mental illness and HIV/AIDS. It indicates that mental illnesses are still regarded as mysterious in the community and there is much stigma and discrimination towards the mentally ill, increasing their vulnerability to HIV infection. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2013

- Description: The constructivist world view is advocated in the Namibian National Curriculum for Basic Education (NNCBE, 2010) since it encourages teachers to use different knowledge sources. This perspective embraces a multicultural approach to science teaching and learning. Indigenous knowledge (IK) and western science (WS) are some of the knowledge sources that are advocated. Yet, it has been noted that some science textbooks used in school science curricula do not consider IK. It is often diminished and considered of lesser value. The sole use of WS in teaching and learning is often distant from IK sources which can be used as prior knowledge. In this study, I therefore endeavoured to minimize this gap in the science curriculum. Essentially, the study focused on investigating trainee teachers’ engagement with prior everyday knowledge and experiences of natural phenomena in teaching physical science concepts. The rationale behind the study emerged while I was supervising twelve trainee teachers on school based studies (SBS) in the Caprivi Region. Observations revealed that learners frequently asked trainee teachers to relate their IK to WS to contextualize what they were learning. However, most trainee teachers seemed to experience challenges. This pedagogical gap and challenge was investigated using the instruments below. An analysis was done on the Namibian National Curriculum for Basic Education (NNCBE, 2010), extracts of research papers and a chapters on pressure in physical science textbooks. A worksheet was used to orientate trainee teachers with suggestions on how IK could be fused with WS to contextualize teaching and learning. Thereafter, this was followed by the simultaneous use of brainstorming and audio-visual techniques. Base line instruments paved the way for the main data generating techniques; namely, microteaching, audio-visual techniques, critical partners’ observation and focus group interview. There was triangulation of data collection instruments which enhanced validation followed by tabulation and data collation to develop themes. Analysis entailed checking theme repetition, indigenous categories and key words in context techniques. Themes enabled the construction of analytical statements which were discussed with reference to the relevant literature, theory and subsequently aligned to the research questions. Findings from this study include the suggestions that IK can be incorporated into teaching and learning of science concepts through the use of models or practical activities, science language used in the community and some cultural artifacts. The relevance of incorporating such type of knowledge is to contextualize science teaching and learning. The study therefore concluded that the incorporation of IK into teaching and learning of science concepts; (a) broadens the curriculum as it addresses conceptual progression and cohesion; (b) contextualizes concepts taught; (c) empowers teachers to use a practical curriculum and (d) it also creates space for misconceptions that come with IK to be identified and corrected. The study thus recommends that cultural artifacts and the social science jargon used in the community of the trainee teachers can be used to incorporate IK with WS as these types of knowledge are not mutually exclusive but in fact complement one another.

- Description: This thesis explores the difference between the vision of citizenship within education policy and the actual experiences and understandings of citizenship by Matric learners. Citizenship as envisioned in policy is shown to differ significantly to citizenship as understood and experienced by the interview participants. The citizenship envisioned in policy presents the goal of an equal and united citizenry whereas interview participants described citizenship as unequal and hierarchical. In particular, the racial hierarchy enforced under Apartheid was found to dominate the learners’ experiences of citizenship. Despite progressive legislation, distribution of opportunities remains heavily weighted in favour of those in high-income environments. Education policies that determine the overall structure of the South African education system were selected for analysis. These are the Constitution, the South African Schools Act and the National Education Policy Act. These policies are analysed and a vision of South African citizenship is described as possessing the following characteristics. A common, equal citizenship in a united and transformed South Africa. A citizenship encouraging and mandating critical engagement, dialogue, openness and transparency. A citizenship founded on quality of life for all and developing the potential of each individual. A citizenship in which both state and citizen are responsible and accountable and operate within the rule of law. A citizenship underpinned by human dignity and freedom and security of the person. A citizenship in which there is respect for difference and self-determination and in which ‘unity in diversity’ plays a key role. Matric learners were drawn from three different schools in an area of Kwazulu-Natal. Each of these schools represents a ‘type’ of school in South Africa: a former Model C school, an independent school and a school based in a rural or township area. The interviews aimed not only to understand citizenship from the perspective of these learners, but also to understand how experiences of citizenship varied depending on race, gender and class.

Unearthing the essence of nature and the perception of the natural landscape among the amaXhosa in the Eastern Cape : an exploratory study

- Description: The recognition of the close link between the lifestyles of 'indigenous' and 'local' people and biodiversity is widely acknowledged as crucial, not only for the survival of biological diversity but also for the protection of cultural diversity. Most discussions centre on the argument that cultural diversity can, through a wide variety of uses and practices, sustain and conserve biodiversity, particularly in many developing countries. However, local people's relationship with natural landscapes and the extent to which they value biodiversity has not been fully explored and is in most cases misunderstood, which in fact undermines the bio-cultural diversity link. This misunderstanding exists primarily because the majority of environmental or ecological research conducted so far has been oriented towards economic valuation, in quantifying the estimated value of plants and fauna utilised by local people. As a result, biodiversity is primarily treated as a commodity, with wild harvested plant products being classified as either having subsistence, or commercial and medicinal value. This approach is narrow and conceals the critical, profound noneconomic values of biodiversity among local communities in everyday life. Literature indicates that biodiversity and natural landscapes also include less tangible values such as spiritual, cultural, psychological and social values (e.g., sense of place, place attachment, and psychologically restorative effects) which are crucial to human well-being. This suggests that human-nature interaction is complex, and that the meanings and values that people ascribe to natural landscapes cannot be solely reduced to economic values. Nevertheless, to date, studies investigating these less tangible values have received little attention in South Africa. As a result, we have very little understanding of what local and indigenous communities value or appreciate with regard to natural landscapes, beyond their general economic significance. This study seeks to address this particular limitation by exploring non-economic values of natural landscapes and their significances to local people while illuminating the complexities inherent in human-nature interactions. I argue that the purely economic valuation of natural resources is simplistic and biased, and therefore does not represent the complete meaning and significance that natural resources may hold for local communities and households. Therefore, this study takes an innovative psychological approach to explore in detail the everyday lived experiences of the amaXhosa in the Eastern Cape, South Africa. It seeks to investigate the cultural, spiritual, and psychological values that ordinary people attach to natural landscapes in the peri-urban and urban communities of Ndlambe Village l and Grahamstown respectively. This research also aims to study the general perceptions of and meanings ascribed to the natural landscape (referred to by the amaXhosa as ihlathi lesiXhosa). In addition, it carefully integrates the Phenomenological and Transactional approaches to investigate how the amaXhosa engage, interact, and find meaning within the natural landscape. Furthermore, the study explores the impact of such landscape experiences on local people's spiritual and psychological well-being, demonstrating it link to bio-cultural diversity and conservation. The major findings in this study reflect that ihlathi lesiXhosa provides a place for peace and tranquillity to enhance psychological restoration. Moreover, ihlathi contributes towards redefining and strengthening personal and cultural identity; and provides spiritual satisfaction in everyday life. Overall, the findings of this study indicate that i!liathi lesiXhosa plays a profound role in both the personal and social lives of many amaXhosa in the Eastern Cape in that it appears to improve their lives. Therefore, the evidence in this study suggests that, among the amaXhosa, biodiversity and natural landscape management processes should not aim to address and promote ecologicallbiological and economic values in a compartmentalized manner independent of other social, cultural, psychological, and more specifically the spiritual values of these features. An increased understanding of these more intangible values and local people's value system of biodiversity could help towards implementing improved biodiversity conservation and landscape management strategies in South Africa. These insights would not only help us to address the challenges of the previous conservation framework but would also encourage a more inclusive, mutual benefiting process that respects local people's values and needs.

- Description: The convergence of previously distinct networks into an All-IP network has resulted in an increase in the number and diversity of devices, channels and communication networks available to users. This has increased the number commu-nication options available and is evidenced by the number of different communication devices owned and services subscribed to. How-ever, this has created complexities that call for proper methods to manage these diverse and in-compatible communication options. The objective of Unified Communication (UC) is to seamlessly integrate the dispar-ate communication channels into a device independent plat-form that can easily be managed by users. Due its focus on a largely urban and highly connected market, UC has not benefited marginalized communities. This paper discusses the design and implementation of Unicorn, a UC solution for a middleware software platform called Teleweaver which was designed to support the development of services for marginalized communities. The solution integrates services from a telecommunication container called Mobicents. It seamlessly amalgamates voice, data and video onto one device independent unified platform easily accessible by users.

- Description: spending is regarded to be one of the major contributors to economic growth. The purpose of the study was to investigate how infrastructure projects could engender professional skills development. The topic is focused on a human resource (HR) perspective as it is one of the knowledge areas in project management. In order to achieve the research objectives and also establish the breadth of the subject issues in the literature review, a qualitative methodology was employed. Interviews were conducted and the majority of the participants were working towards professional registration in the built environment professions. The empirical findings that emerged from the study show that the majority of the respondents agreed that HR units should be aware of the legislation related to professional training and education. The interviewees further elucidate that, although professional registration is the primary duty of the candidate, HR units should ensure that interns are doing what is in line with their professional requirements, according to different councils, to ensure compliance. However, the lack of a structured approach in administering training programmes is a key factor that contributes to the lack of development of professional skills on government sponsored infrastructure projects. This must be addressed to attain the desired professional development outcomes among historically disadvantaged individuals (HDIs) that are keen on professional registration and development in the built environment professions. Other empirical findings showed that most of the respondents showed some concern regarding job security with their present employment.

- Description: spending is regarded to be one of the major contributors to economic growth. The purpose of the study was to investigate how infrastructure projects could engender professional skills development. The topic is focused on a human resource (HR) perspective as it is one of the knowledge areas in project management. In order to achieve the research objectives and also establish the breadth of the subject issues in the literature review, a qualitative methodology was employed. Interviews were conducted and the majority of the participants were working towards professional registration in the built environment professions. The empirical findings that emerged from the study show that the majority of the respondents agreed that HR units should be aware of the legislation related to professional training and education. The interviewees further elucidate that, although professional registration is the primary duty of the candidate, HR units should ensure that interns are doing what is in line with their professional requirements, according to different councils, to ensure compliance. However, the lack of a structured approach in administering training programmes is a key factor that contributes to the lack of development of professional skills on government sponsored infrastructure projects. This must be addressed to attain the desired professional development outcomes among historically disadvantaged individuals (HDIs) that are keen on professional registration and development in the built environment professions. Other empirical findings showed that most of the respondents showed some concern regarding job security with their present employment. They explained that once the status of professional registration is attained, securing employment in the industry should be relatively easy. South Africa needs a highly skilled workforce to ensure growth of the economy therefore HR departments in organisation should adapt a systematic approach in their HR planning in order to ensure skills are engendered to HDIs as well.

- Description: This thesis presents an update to the ionospheric propagation factor, M(3000)F2, global empirical model developed by Oyeyemi et al. (2007) (NNO). An additional aim of this research was to produce the updated model in a form that could be used within the International Reference Ionosphere (IRI) global model without adding to the complexity of the IRI. M(3000)F2 is the highest frequency at which a radio signal can be received over a distance of 3000 km after reflection in the ionosphere. The study employed the artificial neural network (ANN) technique using relevant geophysical input parameters which are known to influence the M(3000)F2 parameter. Ionosonde data from 135 ionospheric stations globally, including a number of equatorial stations, were available for this work. M(3000)F2 hourly values from 1976 to 2008, spanning all periods of low and high solar activity were used for model development and verification. A preliminary investigation was first carried out using a relatively small dataset to determine the appropriate input parameters for global M(3000)F2 parameter modelling. Inputs representing diurnal variation, seasonal variation, solar variation, modified dip latitude, longitude and latitude were found to be the optimum parameters for modelling the diurnal and seasonal variations of the M(3000)F2 parameter both on a temporal and spatial basis. The outcome of the preliminary study was applied to the overall dataset to develop a comprehensive ANN M(3000)F2 model which displays a remarkable improvement over the NNO model as well as the IRI version. The model shows 7.11% and 3.85% improvement over the NNO model as well as 13.04% and 10.05% over the IRI M(3000)F2 model, around high and low solar activity periods respectively. A comparison of the diurnal structure of the ANN and the IRI predicted values reveal that the ANN model is more effective in representing the diurnal structure of the M(3000)F2 values than the IRI M(3000)F2 model. The capability of the ANN model in reproducing the seasonal variation pattern of the M(3000)F2 values at 00h00UT, 06h00UT, 12h00UT, and l8h00UT more appropriately than the IRI version is illustrated in this work. A significant result obtained in this study is the ability of the ANN model in improving the post-sunset predicted values of the M(3000)F2 parameter which is known to be problematic to the IRI M(3000)F2 model in the low-latitude and the equatorial regions. The final M(3000)F2 model provides for an improved equatorial prediction and a simplified input space that allows for easy incorporation into the IRI model.

- Description: Liposomes are small phospholipid vesicles that have been widely investigated as drug carriers for the delivery of therapeutic agents. A variety of liposome formulations are presently under clinical trial exploration, while others have already been approved for clinical use. The aim of this study was to optimize liposome uptake into bacterial cells. Both gram-positive and gram-negative bacteria were used in the study as well as Candida albicans.Response surface methodology (RSM) using a central composite design (CCD) model was used to optimize liposomal formulations of carboxyfluorescien (CF) for each of the three microbes, and also the three microbes in combination namely; Staphylococcus aureus (Sa), Escherichia coli (Ec) and Candida albicans (Ca). Percentage of CF encapsulated and CF increase in Uptake were investigated with respect to two independent variables that were, cholesterol (CHOL) and stearylamine (SA) content. Design Expert 8 was used for the purpose of finding the combination of independent variables that would yield an optimal formulation for each microbe and the three microbes in combination. The model selected by the software managed to reasonably correlate the predicted models to the experimental data. Encapsulation of carboxyfluorescien (CF) into a liposome formulation enhanced its uptake by Staphylococcus aureus and Escherichia coli as well as Candida albicans. This was evident in the increase in CF uptake when the uptake rate of free CF was compared with that of liposomal CF.

- Description: Pollution of aquatic resources in Uganda is on the increase and the trends are expected to increase with increase in population size and urbanisation. Assessment and mitigation of the environmental impacts on water quality and biodiversity have now become necessary. The aim of the study was to integrate invertebrate and fish as bioindicators and fish histopathology as a biomarker in the assessment of water quality deterioration in urban wetlands in Uganda. The integration harnesses the advantages and counteracts the shortcomings of each method and thus builds a more robust diagnostic tool that gives a better view of the impacts to the entire ecosystem. Four endpoints which included, physicochemical variables, benthic macroinvertebrate bioindicators, fish bioindicators and fish histopathology biomarkers were compared between varied effluent-impacted wetlands (Murchison Bay in Kampala, and Kirinya, Masese and Winday Bay in Jinja) and a non-impacted reference wetland (Lwanika in Mayuge). Results from the effluent-impacted sites differed from the less impacted reference site. The two sampling locations at Murchison Bay (inshore and offshore) and one sampling location at Kirinya (inshore), that were highly impacted with urban effluent, showed elevated nutrient levels, low pH, dissolved oxygen and secchi depth readings. This corresponded with low invertebrate taxa and fish species diversity and richness; and severe histopathological responses in liver, gonads and gills of O. niloticus. Sensitive taxa such as ephemeroptera and trichoptera were completely absent while pollution tolerant taxa Chironomus sp, Corbicula and Oligochaeta were present. Also notable was the absence of many native haplochromines and presence of mainly Brycinus sadleri, Oreochromis niloticus and leucostictus. The organs manifested high prevalence of severe inflammatory and regressive changes and higher organ indices that fell within the pathological category. These sites were consistently classified as highly polluted under the four endpoints. The reference site was classified as least polluted while Masese and Winday Bay were moderately polluted. Results suggested that the approach of using invertebrate and fish as bioindicators and the fish histopathology as a biomarker, in relation to water quality physicochemical variables was a useful tool in highlighting the spatial differences in environmental quality.

- Description: Globally, mobile technology use, particularly the use of mobile phones, is becoming increasingly widespread. One consequence of this growth is mounting interest in using mobile technologies in the public sector, particularly in developing countries, because it is seen as enabling better access to information and services for citizens. Mobile government (m-government), defined as the use of mobile technologies and applications for public sector services, promises to extend access to public services to marginalised sectors of the population and is emerging as a new focus in the ongoing challenge to provide efficient, effective and accessible public services. Though interest in m-government is emerging in the provincial Western Cape Government (WCG) of South Africa, few guidelines exist in the WCG to inform the development of public sector mobile services. This absence impacts on service delivery and the primary objective of this study was to propose a set of guidelines that could guide the prioritisation of citizen facing public sector services for mobile implementation in the Western Cape. The study considered two areas namely, government and user needs. The primary research question was to determine what public sector services citizens need and how these services should be prioritised for mobile delivery in the Western Cape. To address this, three research sub-questions were formulated. The first question aimed to examine conceptions of mobile government. To achieve this a literature study and documentation review was conducted, from which factors influencing service prioritisation emerged. The second research question aimed to identify citizen needs that could inform mobile public sector services in the Western Cape. Thus a survey and interviews were conducted with citizens using the WCG community ICT centres (e-Centres). The third research question aimed to identify factors that impact on the prioritisation of citizen facing public sectors for mobile delivery in the Western Cape. The findings from the literature study, survey and interviews conducted were used to address this research question. The results from the three research sub-questions were triangulated to address the main objective of the study and from this a set of guidelines for prioritising mobile public sector services in the Western Cape was proposed.

- Description: This paper presents evidence of establishment of a loricariid population in the Nseleni River in South Africa and uses a unified framework to determine its invasion stage. Specimens were identified morphologically as Pterygioplichthys disjunctivus (Weber 1991), but genetic barcoding results indicated close association with specimens that may have a hybrid history. The species was introduced into South Africa via the pet trade and the first record of introduction into the wild was in 2004. Samples collected in 2011 and 2012 demonstrated that there were multiple length cohorts in the population including juveniles (12–130 mm total length TL) and large (>300 mm TL) adult fish. Gonadal assessment of adults demonstrated the presence of reproduction capable specimens. The concurrent occurrence of mature adults and juvenile fish demonstrated establishment. Locality records indicate that P. disjunctivus has already spread between two rivers through an inter basin water transfer. Using a unified framework for invasions this invasion was categorized as a self-sustaining population in the wild with individuals surviving and reproducing a significant distance from their original point of introduction. Containment is suggested as potential management strategy.

- Description: In the context of higher education in South Africa and drawing on the author's experience as a lecturer in two higher education institutions (HEIs), this article presents her attempts to bring together - and into balance - teaching, supervision and research in an endeavour to offer a transformative learning experience for her post graduate students. It does this by foregrounding student assessment in the Master of Education (MEd) degree in the field of Educational Leadership and Management (ELM) where the development of a half thesis, underpinned by research, stands as the evidence of success. The author suggests that the MEd (ELM) degree be conceptualised differently in order that the half thesis be permitted to gestate over a two-year period. Within this conceptualisation, she argues that inspired teaching and meaningful research is best attained through a community of learning approach which seeks to foreground participatory learning, the advancement of scholarly discourse and the development of student agency. Through the use of a case study, the author provides evidence to suggest that a range of authentic assessment strategies which are purposeful and in alignment with the teaching strategies, the content and the intended outcomes of the qualification being taught are essential. She further argues that well-crafted, formative, recursive and sustainable feedback is an essential part of the gestation process.

- Description: The study looks at how the library users at Zamukulungisa Campus of the Walter Sisulu University (WSU) in the Eastern Cape in South Africa perceive the print media versus electronic media as sources of information for their requirements. The study is aimed at investigating the extent of use of these media by the users of the institution under study and their reaction to print versus electronic media. It is understood that the Zamukulungisa Campus of the WSU users come from different backgrounds. Some come from underdeveloped rural areas where there are no basic amenities available such as running water, toilets, telephones or even electricity and libraries. These types of users depended on information from text books and from their teachers only. The rationale for the study is to examine the students‟ use of print and electronic materials available in the library of the institution under study with the view to identifying the gaps that need to be addressed in order to make recommendations to enhance the effectiveness of the service provision of information to the users by the librarians. With this purpose in mind, the study looks at: the frequency of library use; the nature of the media available in the library; the tools utilized by the users to access the media in the library; the preference of the library users for media usage; the users‟ perceptions and reactions to print and electronic media; the effects on users and; the background to the use of print and electronic media. A questionnaire was used to collect data for this research study from sampled students at Zamukulungisa Campus of the WSU. The findings may lead to potential solutions based on the users‟ reactions to the recommendations of their use of the print and electronic media. The references used are shown in the bibliography.

- Description: This study investigates the valuation of Internet-based businesses. In particular the influence of the implementation of an e-business strategy on the value of a business by focussing on its financial performance, will be determined. Although the valuation of businesses in general has been researched extensively, research on the valuation of Internet-based businesses produced contradictory findings. No consensus could be reached regarding the most appropriate valuation approach to be used. Some research findings indicated that the discounted cash flow approach was the most appropriate while others stipulated that a new valuation approach should be developed. Many authors state that the move to include an e-business strategy is natural, and that businesses cannot afford not to include some form of e-business strategy. Previous research has also shown that by including an e-business strategy, it is possible to improve efficiency of the business and ultimately increase profitability. However, there was no emphasis on how the e-business strategy will influence the business valuation. In order to establish whether an e-business strategy will create value for a business, an empirical investigation was undertaken.

- Description: Value and size related equity investment strategies are supported by a large body of empirical research that shows a persistent premium, both longitudinally and crosssectionally. However, the competing rational and behavioural finance explanations for the success of these strategies are a subject of debate. The rational explanation is that the premium earned on value shares or shares of small companies can be attributed to higher risk. Behaviouralists argue that such shares are not riskier and attribute the premium to cognitive errors and biases in human decision making. The purpose of this study is to determine, firstly, whether the value and size premium exist in South Africa during the period July 2006 to June 2012, which includes one of the worst equity market crises in history. Secondly, this study sets out to determine whether the premium earned on value and size strategies are adequately explained by the principles of rational finance theory. To provide evidence regarding the existence of the value premium and size effect, returns are analysed, cross-sectionally, on portfolios of shares sorted by value and size. For evidence of a rational explanation, returns are regressed on value and size variables, and the relative riskiness of value and small companies is analysed. The results show evidence of a value premium in portfolios of small companies, but not big companies. The size effect is found not to be statistically significant. While regressions do show significant relationships between value and size variables and returns, these variables are found not to be associated with higher levels of risk. The conclusion is that the evidence does not support a rational, risk based explanation of the returns

- Description: This study investigated the vegetation and soil characteristics in relation to distance from water points under different land management systems in semi-arid rangelands of South Africa. Six study sites, two each from communal grazing, commercial farming and game reserves were selected. Two watering points were selected in each study site. Two 500 m transects were laid from the selected watering points. Each transect was divided into sub-transects at 25 m, 50m, 100m, 200m, 300m and 500m from water points. A 100 m2 plot was marked in each sub-transect to record grass biomas, species composition, structure and distribution of woody vegetation and physical and chemical soil properties. Data were collected for two seasons 2012/13 (winter and summer). Thirty and 41 grass and woody species respectively were identified in all study areas. The most common and dominating grass species include Cynodon dactylon, Digitaria eriantha, Eragrostis obtusa, Setaria sphacelata and Sporobolus fimbriatus. Cynodon dactylon and S. sphacelata occurred more abundantly (p < 0.05) in the game reserves than in the other land management catergories. All the grass species had similar (p > 0.05) abundance along distance gradient from water points. Grass dry matter (GDM) showed significant differences (p < 0.05) between and within land management systems. However, GDM was not significantly affected by season, location of water point within each farm or reserve and distance along water points. Acacia karoo, Coddia rudis and Ehretia rigida were the most dominant woody species. Tree equivalent (TE) density of all encroaching woody plants combined was significantly (p < 0.05) higher on the communal area (1732 TE ha-1) than the commercial ranches (1136 TE ha-1) and game reserves (857 TE ha-1), but with no marked variations along distance from water points under all the land management systems. The electric conductivity (EC) was significantly (P < 0.01) higher in game reserves than in communal grazing areas and ranches. Soil organic matter percentage showed greatest and lowest values in the game reserves and commercial respectively. Soil pH and bulk density did not vary but soil organic matter (SOM), EC, bulk density and soil compaction were significant different with no increasing or decreasing trends. Soil properties were affected by herbivore pressure and trampling around water points with inconsistence magnitude and direction. In conclusion, grass species composition and GDM did not respond to distance from water points because either grazing gradient was absent or the length of transects was not enough to explain the absence or presence of gradients. High proportion of A. karoo and high densities of seedlings and saplings would seem as very good indicators of the woody vegetation changes in the different land management systems and distance from water points. The soil quality indicators around the water-points showed that livestock and game affected soil parameters.

- Description: As a centre with a brief to encourage "more and better" health journalism in South Africa, we've had to think hard about definitional issues and about balancing subjective and objective gauges of quality. We've developed an initial appraisal of health journalism, locally and internationally, and we've created a normative framework that we hope will enable journalists and educators to have better discussions about what is meant by quality in health journalism. This framework will hopefully inform what kind of journalism education - degrees, short courses, topic guides, symposia - might promote higher levels of quality in reporting on medical science.
