- Description: Background to the academic research. Hilton College is an all boys private school in the Kwa-Zulu Natal Midlands. Since the beginning of 2012 boys have been permitted to carry their phones during the school day, (Thomson, 2012). Wireless internet access was also extended across the campus to allow boys and staff to bring their own devices to class and have access to the internet (Machlachlan, 2012). In the past, communication between staff and boys was either verbal or through the use of a daily notice, called the Daily Routine Order (DRO). The DRO is placed at the dining room tables each day and boys are expected to check for any notices that may pertain to them. These notices are emailed to a secretary who prints them out and places them in the dining room each day at lunch. 2. Objectives to the research. This research sought to establish whether current communication methods were effective or whether the prevalence of mobile phones and wireless devices had presented the school with a more effective method. It was important therefore, to investigate what devices were on campus, how those devices were used and when they were used. In addition to this, the research sought to establish communication preference among staff and boys. 3. Research Methodology. The research was conducted through the use of a qualitative survey that was conducted among both staff and boys. Staff and boys were surveyed to establish generation, device prevalence, device usage and device preference. This data was collected using an anonymous qualitative survey that was administered through the use of Google docs in the school labs. 187 Boys in 3 grades 8 and 9 participated in the survey along with 18 staff members. The data was then analysed and compared to data from similar research that had been conducted elsewhere in the world. Because of significant age differences between boys and staff it was critical to establish whether device usage among staff and boys was tied to their generation. Of particular interest were the device behaviours associated with the Millennial generation, who were born between 1982-2002 (Strauss 2005:10). This generational ‘benchmark’ allowed the researcher to compare the Hilton College cohort to those whose device behaviours and usage had occurred and been discussed in generational research elsewhere. It also allowed for certain assumptions to be made about staff and boys based on their generational profile. 4. Findings It was found that staff and boys exhibited communication traits that were consistent with their generation and consistent with other research in this field. It was also found that staff and boys preferred mobile and digital forms of communication over verbal announcements and the DRO system. For this reason, it was recommended that the Hilton College establish a system that took advantage of technology to improve on communication. Various recommendations were given by the researcher that took advantage of current technologies. These included the use of SMS, Instant Messaging, Social Networks and email. It was also recommended that the school consider prescribing devices that allow for communication between staff and boys.

- Description: For the past few years, Namibian grade 11-12 learners’ achievement level in biology has not been very encouraging. Evidence to this effect is contained in recent examiners’ reports which outline misunderstanding and various misconceptions. The causes of these misunderstandings and misconceptions may be varied, but there is credible evidence that some of it is rooted in the language problem for learners. A classroom is a social unit where many social practices are acquired, including the use of English language. Equally, it is a place where errors in language are learnt and reinforced. Triggered by these challenges facing biology learners, a qualitative case study was conducted at two secondary schools in Ohangwena Region, Namibia. Its purpose was to investigate how biology teachers scaffold learners to make sense of biological language and concepts when English is used as the mediational tool. Underpinned by an interpretivist paradigm, the study made use of document analysis, observation (lessons were also video-taped) and interviews to generate the data. Several data generating techniques were used for triangulation and validation. To further validate the data, transcripts of video-taped lessons and interviews were sent back to the research participants for member checking. The data gathering methods were also used in data presentation, analysis and interpretation to determine the extent of scaffold that teachers provide to their biology learners. The main findings of my study are that, despite efforts by participant teachers to scaffold their learners in making sense of biological language and concepts, success rates in this regard remain disappointingly low due to their (teachers) limited pedagogical content knowledge. Teachers therefore require improved mentorship, monitoring and capacity building.

- 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: 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: 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: 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: The southern African region is beset with numerous security concerns: pervasive poverty, deepening inequality, starvation, contamination of essential natural resources, violent crime and state oppression. However, the most vital of the region’s security concerns in the 21st century is the spread of infectious disease. The region shoulders a disproportionate amount of the continent’s infectious disease burden, with diseases such as HIV/AIDS, tuberculosis and malaria claiming more lives every year than any other factor. The nature of these diseases and their propensity to spread, coupled with inadequate regional public health structures pose a significant threat to regional security and stability. The study asserts that southern Africa’s security concerns are most appropriately characterised under the paradigm of Human Security. It further asserts that if such vital threats to human security are not adequately managed they have the ability to permeate across state borders, spelling numerous negative ramifications for the region. To this end, the study details the public health crisis in Zimbabwe and its effects on regional security and stability in southern Africa. An enduring political and economic collapse in Zimbabwe led to the dramatic deterioration of its public health sector, the concomitant mass migration of Zimbabwean nationals across the region presented a unique and complex challenge to the Southern African Development Community (SADC) and its member states. As the premier regional governance institution, SADC has failed to adequately mobilise its structures and member states to respond to the challenges resulting from the public health crisis in Zimbabwe. The study explores the factors accounting for this regional inertia, and asserts that while infectious diseases are at present the most vital of the human security threats, similar threats to human security have the potential to affect the region if SADC fails to recognise and prioritise threats to human security as legitimate regional security concerns.

- Description: Oxytetracycline (OTC) is a broad spectrum antibiotic used extensively in the agricultural and human-health sector, and is effective against various gram positive and –negative bacteria as well as large viruses and certain pathogenic Rickettsiae. This study addresses the lack of voltammetric knowledge regarding the electroanalytical characterisation of OTC and its analysis in complex matrices. Cyclic voltammetry (CV) revealed several irreversible anodic peaks for OTC at a bare glassy carbon electrode (GCE). These current responses were improved through the selection of a diluent for OTC stock preparation, electrolyte solution and electrolyte pH, stir time and applied preconditioning potential. Under enhanced adsorptive conditions and using square wave voltammetry (SWV), a detection limit of 24.3 nM was achieved. The electrode surface could be renewed in vitro for 10 successive scans. OTC oxidation was characterised as a one electron:one proton ECiE mechanisms. Next, investigating the viability of voltammetry in various complex microbiological growth media revealed that selected growth media contained interfering redox active components, which, while simultaneously coating the electrode surface, effectively reduced GCE performance and lowered the active electrode surface area, as ascertained through CV and electrochemical impedance spectroscopy (EIS) studies. This interference lowered OTC current response in the presence of growth media which was partially recovered by appropriate growth media selection and sample dilution. In testing the use of acid functionalised multi-walled carbon nanotubes (MWCNTs) to improve anodic OTC response, charge-based attraction was observed between the MWCNT dispersal agent Nafion® and OTC, while increased surface area associated with prolonged acid functionalisation time aided in improving OTC current response.

- Description: The pharmaceutical industry must worry about managing pharmaceutical waste as it poses a health risk to human beings and its presence in the environment can also contribute to loss of biodiversity. Ngwuluka, Ochekpe, and Odumosu (2011: 11259) state that “Pharmaceuticals, though used to treat and manage diseases, are poisons, which justify the growing concerns about their presence in the environment.” Various forms of pharmaceutical waste exist, Ngwuluka et al. (2011) identified the following forms of pharmaceutical waste: Expired dosage forms, non-reworkable formulations, spilled pharmaceuticals, rejected active pharmaceutical ingredients, expired active pharmaceutical ingredients, and wastewater resulting from the water used for process operations during manufacturing and could come from the water used to clean equipment, pipes and floors, and would contain amongst other materials, chemicals and active pharmaceutical ingredients (APIs). A review on the pharmaceutical industry and the progress they have made in environmental management by generating health, safety and environmental programs, preventing pollution, waste minimization, recycling and reusing materials, investing in projects and facilities to ensure environmental sustainability have been established (Berry & Rondinelli, 2000). Dr. Reddy’s Laboratories is an Indian based pharmaceutical company which imports, markets and sells medicines in South Africa. Dr. Reddy’s has plans to set up a manufacturing plant in South Africa. The purpose of this study is to research waste management practices at Dr. Reddy’s plant in India and to draw parallels between India’s and South Africa’s waste legislation. This is to enable Dr. Reddy’s to review all aspects of its waste management systems, in order to revise where necessary and to improve the overall achievement of its waste management objectives in order to become a more sustainable organisation and to meet South African Waste legislation before setting up a plant in South Africa. 3 ii. Objective of the Evaluation Report The purpose of this research is to evaluate and analyse the development and implementation of a waste management system in a pharmaceutical company, specifically Dr. Reddy’s Laboratories. This is primarily to enable the company to review and analyse all aspects of waste management pertaining to pharmaceutical manufacturing and to revise or improve where necessary to ensure adherence to waste regulations as outlined by government. The following research goals have been also been identified: To identify and describe waste management practices at Dr. Reddy’s Laboratories, on the inherent assumption by the researcher that the company has a successful waste management strategy that would need to be reviewed to identify areas of improvement before expanding manufacturing facilities into South Africa. To evaluate, assess and compare similarities and/or differences between the identified South African Legislation for Waste Management with those identified during research conducted at Dr. Reddy’s iii. Importance of the Research Conducted Waste Management is important in that it not only removes from the environment, substances that can be harmful to humans and animals but it also enables an organisation to be more sustainable. According to Seadon (2010: i) “Integrated waste management is considered from a systems’ approach, with a particular emphasis on advancing sustainability”. The study will provide guidance to senior management, shop floor managers and employees who work in Dr. Reddy’s manufacturing plants as well as overall employees at Dr. Reddy’s on how to successfully implement a Waste Management programme to enhance sustainability at the organisation and realise the benefits to the organisation of being more sustainable. Weybrecht (2010) identified the following benefits that companies could gain by adopting sustainable waste management practices: reduced costs, resource preservation, keeping up with legislation, enhanced reputation, business differentiation from competitors, and attraction and retention of quality employees, and customer need satisfaction amongst many other benefits. This research needs to address the gap in analysing waste management practices (with more emphasis on waste treatment, waste minimisation, re-use, recycling and disposal), and implementation and understanding of waste management in the pharmaceutical industry as prior research was done mostly in other chemical industries and not to a large scale in the pharmaceutical industry. South African Waste Legislation, Indian Waste Legislation (as Dr. Reddy’s is based in India), as well as International Pharmaceutical Waste Management Guidelines, and International Pharmaceutical Good Manufacturing Practices provide a framework and benchmark of leading pharmaceutical waste management practices that can guide Dr. Reddy’s Laboratories’ leadership into integrating their waste management practices into their plans of setting up a manufacturing plant in South Africa. 5. Research Methodology This is evaluation research in the form of a case study and the data collection method employed is the conduction of a survey through questionnaires. The evaluation research also involves a document analysis of the organisation’s 2011 and 2012 annual reports, Dr. Reddy’s 2010 Sustainability Report as well as literature compiled by the organisation’s Corporate Communications Division. The research would also include review of existing literature on waste management. v. Structure of Dissertation This dissertation consists of three sections. Section 1: The Evaluation Report The section introduces the research area, provides the objectives of the research, provides contextual background information and describes the rationale for conducting the research. This section further describes Dr. Reddy’s waste management practice as outlined in relevant company documentation; it is also intended to highlight the specific waste management processes that were followed in the formulation and implementation of the waste management strategy. This section further describes the sample and presents the results of the survey, where the results are collated and reviewed in the context of the criteria set in the South African Waste Legislation, Indian Waste Legislation, as well as in International Pharmaceutical Waste Management Guidelines, and International Pharmaceutical Good Manufacturing Practices. The overall findings of this case study suggest that although management at Dr. Reddy’s are satisfied with waste management practices and results achieved at it manufacturing plant, there is however dissatisfaction amongst employees who believe the organisation has not successfully disseminated information and sufficiently trained them on waste management policies, processes and practices. There is therefore a desire amongst employees to be trained and to see the company improve on its waste management processes, this desire is a very important attribute as it indicates that employees at Dr. Reddy understand and are committed to the importance of waste management. Future research should be conducted to measure the legal impact of non-compliance to legislation governing waste management in the pharmaceutical company. Section 2: Literature Review The objective of the literature review is to provide a critical assessment and evaluation of previous research in the field of waste management in general as prior research was done mostly in other industries and not to a large scale in the pharmaceutical industry. The literature review evaluates the key elements of an effective waste management strategy implementation and is followed by a review of literature pertaining to the description of Pharmaceutical waste. Section 3: Research Methodology This section presents a description of how the work in this research was conducted. It presents the research process followed in compiling this case study, represented by the aims and objectives, research methodology and design, data collection techniques and data analysis.

- Description: Effective leadership has been found to be a key determinant of organisational success. Effective leadership does not only involve the ability to influence and inspire others, it is the ability to lead subordinates according to the competencies that they value. The focus of this study is on determining what in fact the future South African graduate workforce will value in a leader. Effective leadership and the competencies that subordinate's value is especially relevant today as leadership is forced to contend with an increasingly diverse workforce. This diversity necessitates the need for a leadership style to be congruent with what subordinates of diverse genders and cultures will value, so to be effective. Existing studies have indicated that gender and culture influence what subordinate's value in a leader, however it is evident from the results of this study, that this is not entirely the case. Regarding gender, the female and male respondents in this study value similar competencies in their leader, indicating that there is no distinct set of competencies that will be valued by male and female graduates. With respect to culture, the respondents value a mixture of competencies that combine both African and Western leadership practices, values and philosophies, indicating that there is no distinct set of competencies that will be valued by African, Coloured, Indian and White graduates. On the basis of this research, the recommendation is that for leaders to be effective in the 21 st century, a leader must be loyal and inspirational, have vision and integrity and lastly must be open and honest with their subordinates

The focus of this study is on determining what in fact the future South African graduate workforce will value in a leader. Effective leadership and the competencies that subordinate's value is especially relevant today as leadership is forced to contend with an increasingly diverse workforce. This diversity necessitates the need for a leadership style to be congruent with what subordinates of diverse genders and cultures will value, so to be effective. Existing studies have indicated that gender and culture influence what subordinate's value in a leader, however it is evident from the results of this study, that this is not entirely the case. Regarding gender, the female and male respondents in this study value similar competencies in their leader, indicating that there is no distinct set of competencies that will be valued by male and female graduates. With respect to culture, the respondents value a mixture of competencies that combine both African and Western leadership practices, values and philosophies, indicating that there is no distinct set of competencies that will be valued by African, Coloured, Indian and White graduates. On the basis of this research, the recommendation is that for leaders to be effective in the 21 st century, a leader must be loyal and inspirational, have vision and integrity and lastly must be open and honest with their subordinates

- Description: This book of poems ranges in style from narrative to condensed lyric moment, and shifts in perspective from observation to introspection. Thematically, these poems explore everyday life through its many manifestations – memory, nature, marriage, faith and death – with an emphasis on finding meaning in absolutely ordinary things. Though their tone is often vulnerable and tender, even when it is more distant the poems are always searching.

- Description: This study emerged from the high prevalence rate of HIV and AIDS infection among women in Sub-Saharan Africa, which has no exception to Namibia. Women have been vulnerable to HIV and AIDS let alone on sex related issues since the epidemic emerged, but not research has been done specifically to Okalongo women. The way in which women vulnerable to HIV and AIDS infection were explored by examined social and cultural identities that affect women’s sexual relations in negotiating sex and safe sex. Qualitative study on a sample of fifteen women was conducted in Okalongo. The purpose of this study was to investigate the conceptions and experiences of women in negotiating sex and safe sex with their husband and partners. Feminist theory guided the methodology and analysis of data. I assumed that gender roles andsexuality are socially constructed, shaped by religion, social, political, and economic influences and modified throughout life. Feminist theory assisted in documentary the ways in which the female’s gender and sexuality in Okalongo is shaped by cultural influences and by institutions that disadvantage female and other oppressed groups by silencing their voices. The feminist further guided the discussion of the contradicting messages about women’s sexuality and their experiences, as women complied, conformed and even colluded with their oppression. To address the issue under study, the primary analysis of data from the focus group discussion and individual interview were utilised. The following themes were the heart of analysis: Women Positionality, Normalisation and Compliance, Women Agency and Male Dominance Power, Women Perceptions of Risk, Sex Education in and out of school among Women.In this study the data suggested that women in Okalongo are more vulnerable to their lack of assertiveness, as they have difficult in developing an authoritative voice, they tend to be humble about their achievements and knowledge and to only assertively when concerned about others. The findings supported the literature that women’s vulnerability is strongly influenced and tied by broader forces present in the society. Women’s vulnerability is real and needs to be tackled for any progress to occur in the fight against AIDS. Until factors that constraints and enabling women agency to negotiate sex and safe sex acknowledged and addressed, women will continue to succumb to the HIV pandemic.

You don't love your mother just because she feeds you : amaXhosa and woodlands in the Peddie district, Eastern Cape

- Description: This thesis will discuss how the application of place theory might provide insight into how a selection of Xhosa-speaking people in a rural village (Ntloko), in the former Ciskei of the Eastern Cape, interact with and establish relationships with the local indigenous thicket forest (ihlathi). I am concerned with how these influence residents' perceptions and attitudes (relational epistemologies) towards this resource, and how these may (or may not) translate into conservation practices. I am also interested in how socio-political and economic changes have altered these people/place relations (including gender) and their corresponding cultural perceptions. It is argued that the local thicket forest's significance and importance moves beyond the economic and utilitarian value of its natural resources. The thicket plays an important part in local identity construction, due to both its socio-cultural significance and its role in local livelihoods. People form meaningful attachments and relationships (relational epistemologies ) with the thicket as a place, through their interactions with it. While this may or may not result in actions and attitudes in-line with the conservation agenda, it is shown that this relationship is necessary for a local concern and stake in the natural environment. Those who have no or minimal interaction, such as many of the young women of Ntloko, have no opportunity to forge a relationship with it. Ihlathi may be known through narrative, but not personal experience, and as such no significant attachments can be formed, and thus concern for its conservation status is irrelevant. It is clear that if you remove people from an environment, you remove the stake they hold in the environment in question, thereby disrupting the relationship, and alienating people from nature. While a relational epistemology may not equate to conservation practices, it does imply a stake or concern in the environment, and as such, may provide an opportunity for conservationists to work with local communities. Resistance to conservation and development projects that aim to exclude local interaction, and therefore relationships, with the environment, will always be strong when local identities are intricately tied to the places and experiences that form them. Threatening that relationship threatens local identities and the attachments that orient them.
