- Description: The demand for university education has increased at a higher rate than the resources available for universities to offer the required services. In Kenya, the demand for university education has continued to rise with university enrolment increasing tremendously over the last four decades. This growth calls for an investigation to find out the impact of this expansion on service delivery in universities. Kenya has thirty-nine fully-fledged universities that have been accredited by the Commission for University Education (as at 31st March 2013). Twelve others are operating with interim letters of authority (ILO). This development has created competition amongst universities and, as a result, necessitated the development of strategies to ensure survival in this changing environment. The review of existing literature on this subject has established that service delivery is a service differentiator and therefore could be utilised by universities to gain a competitive advantage and therefore enhance their overall performances. Based on this background, this study sought to establish the influence of service performance measurement on service delivery in relation to the expectations of university students in Kenya. Secondary sources were used to formulate a theoretical model of the influence of service performance measurement on service delivery that guided this study. The theoretical model indicates that non-academic aspects, academic aspects, reputation, programme issues and access factors may influence service delivery at the university. These five dimensions were used in the study as the independent variables of service delivery at the university. The outcomes of service delivery at the university were identified as student expectations, student satisfaction, student loyalty and student retention in the theoretical model; these were treated as dependent variables. Hypotheses were formulated that proposed relationships between the independent variables and service delivery. Hypotheses in respect of relationships between service delivery and the outcomes were also developed. A quantitative research approach was adopted to empirically evaluate the relationships between service delivery and the variables in this study. Data for the study was collected through the use of a structured self-administered questionnaire that was distributed to 720 university students in Kenya. Six hundred and thirty useful survey responses were received from fifteen universities. The data collected was subjected to factor analysis and multiple regression analysis to test the hypothesised relationships between the variables and service delivery. Descriptive statistics were also obtained from the raw data. The findings of this study indicate that non-academic aspects, academic aspects and access factors have positive and significant influence on service delivery in Kenyan universities. The quality and adequacy of academic, entertainment and sports facilities together with increased accessibility to services by students are important factors that influence service delivery at a university. The university students would like to be treated with respect and courtesy by academic and administrative staff during these service encounters. The empirical results of the study also reveal that student perceptions of service delivery impacts positively on student expectations, student loyalty and student retention related to convenience as well as student retention related to quality assurance.

- Description: Background: Epidemiological findings indicate a higher risk of muscular thigh strain injury during the latter stages of both halves of soccer match-play, with muscular fatigue highlighted as a key etiological factor in injury causation. Anthropometric, biomechanical and physiological differences present in the Black African population may elicit unique thigh injury risk profiles, different from those of European and American players. Objectives: The purpose of the current research was to investigate the impact of soccer-specific fatigue on the risk of hamstring and quadricep injury in amateur Black African soccer players, in both the dominant and non-dominant legs. Methods: Participants were required to perform a soccer matchplay simulation (SAFT⁹⁰), consisting of multidirectional and utility movements, as well as frequent acceleration and deceleration. Selected physical, physiological and psychophysical responses were collected at specific time intervals throughout fatigue protocol performance. Results: Heart rate responses were observed to increase significantly (p<0.05) in response to the start of both halves, and remain elevated (but showing no further significant increase) during the performance of the remainder of the fatigue protocol. Significant (p<0.05) changes in both concentric and eccentric isokinetic variables of the knee flexors and extensors highlight the effect of muscular fatigue on performance in soccer match-play. Eccentric hamstring peak torque was observed to decrease significantly over time (60°.s⁻ₑ=17.34%, 180°.s⁻ₑ=18.27%), with significant reductions observed during both halves. The functional H:Q ratio at 180°.s⁻ₑ indicated a significant decrease over time (10.04%), with a significant decrease indicated during the second half of the SAFT⁹⁰ protocol. The passive half time interval did not result in significant changes in isokinetic variables. Isokinetic strength, work and power indicated no significant effects of leg dominance.. ‘Central’ and ‘Local’ ratings of exertion were observed to increase significantly (p<0.05) as a function of exercise duration. Conclusion: The overall reduction in both the eccentric hamstring peak torque and the functional strength ratio was illustrated to be similar to that of other soccer-specific fatigue research. As a result, the risk of thigh strain injuries is suggested to be similar regardless of playing level and race. These time dependent changes may have implications for competitive performance and increased predisposition to hamstring strain injuries during the latter stages of both halves of match-play

- Description: Subtropical Thicket is the dominant vegetation biome in the Eastern Cape, and extends through to parts of the Western Cape. It is dominated by Portulacaria afra (spekboom), a woody succulent plant recognised for its importance as an ecosystem engineer and its carbon sequestration potential. Due to excessive grazing from domestic stock, spekboom has been completely removed from some areas. The Subtropical Thicket Restoration Programme (STRP) initiated a large scale restoration programme of planting spekboom cuttings in these degraded areas. Their efforts have been met with varying levels of success and improvement of the programme relies on continuous monitoring and scientific evaluation. I investigated the influence of selected soil properties on spekboom growth, mortality and landscape distribution, at both restoration sites and natural intact areas, and through experiments. Site or location was the most important factor influencing spekboom success at restoration plots, whereby sites in the eastern end of spekboom distribution perform better. Moving westwards slope orientation emerged as an important factor, whereby north facing slopes are preferred by spekboom. Although high levels of soil salinity (NaCl) restricted spekboom growth and affected its health, it could tolerate the levels it was exposed too. Soil pH, above 7, and phosphorous concentration, above 70 mg.kg-1, were the only limiting factors to spekboom survival found in the restoration sites. This preference for acidic soils was mirrored in intact Thicket. However in general, soil is not a major factor influencing spekboom growth and distribution, and spekboom is tolerant of a wide range of soil conditions. Spekbooms constraint is most likely a function of climate, which varies greatly across the biome. This study answered some vital questions regarding the possible influence of soil in spekboom growth and distribution. It disapproved the theory that a catena effect may be responsible for the lack of spekboom growing in bottomland areas. The study also indicates and supports the versatility of spekboom as a plant for restoring degraded lands across a range of different geologies and soil types. To maximise spekboom survival rates, restoration efforts should be focussed towards the eastern end of its distribution and to avoid planting in soils with pH levels higher than 7.

- Description: Student success rates in South African higher education institutions are unacceptable. There are many contextual challenges facing these institutions, some as a result of the legacy of the apartheid educational system and some related to the challenges surrounding increased access to higher education. The impact in terms of the costs associated with re-educating students and the added pressure of readmitting failed students into continually growing classes, are substantial. In addition, there is a growing contention that the level of preparedness of students is declining. All of these challenges place immense pressure on academics to support students and ensure acceptable pass rates. There are numerous factors, both academic and non-academic, which have an influence on academic success including prior academic achievement, the academic experience, institutional expectations and commitment, finances, family support and university support services. Many factors are beyond the control of higher education. Student engagement, however, appears to be one factor over which educators have some control. Student engagement may be defined as student involvement in educationally purposive activities. For the purposes of this study two main factors contributing to student engagement were explored. Firstly, the amount of time and effort that the student spends on academic and other activities that lead to experiences and outcomes that constitute academic success. This factor was termed “student behaviours”. Secondly, the ways in which the institution allocates resources and organises learning opportunities and services in such a way as to induce the student to participate in and benefit from these activities. This factor was termed “institutional conditions”. The main research problem of this study was to determine the influence of student engagement on the academic success of first-year Human Resource Management (HRM) students at Nelson Mandela Metropolitan University. The main research problem had five sub-problems which were addressed through the following actions: A literature study was conducted, highlighting the challenges faced in higher education, building a case for student engagement and identifying the factors that contribute towards student engagement, more specifically the student behaviours and institutional conditions. Semi-structured interviews were also conducted with staff members lecturing first-year HRM diploma students at NMMU, with students registered as second- and third-year HRM diploma students, and with a staff member of the Centre for Teaching, Learning and Media (CTLM) at NMMU, to obtain their views on the nature of student engagement and its impact on academic success, as well as the student behaviours and institutional conditions that contribute towards student engagement. The insights gained from the literature survey and the interviews were incorporated into a survey questionnaire which was developed for use in the empirical study to identify the existence and levels of the student behaviours and perceived institutional conditions that contributed towards student engagement among HRM diploma students who were in their first year of study at NMMU in 2012. The final year marks achieved by these HRM diploma students in their first year of study were obtained and correlated with the levels of engagement identified as part of the empirical study. The results of the study revealed that the respondents demonstrated a fair range of the student behaviours which are conducive to promoting student engagement. Their perception of the existence of institutional conditions conducive to promoting student engagement was good. The results also revealed a significant positive correlation between the average final year mark and “student-staff interaction” for both student behaviours and institutional conditions. A significant relationship was revealed between student behaviours and institutional conditions related to “academic focus”, “student-staff interaction” and “social integration”. In exploring the relationship between selected demographic variables and academic success, living arrangements emerged as an important consideration in promoting academic success as all the respondents who failed, lived far from the university. First generation learners were found not to achieve the levels of success of their peers who have had exposure to family members and significant others with tertiary experience. Overall the importance of good relationships between students and staff in promoting engagement and ensuring academic success emerged as an important factor. The importance of improving student success rates should be of paramount importance to all educators. The factors contributing towards student success are numerous and vast. Educators who understand the nature of student engagement and are aware of the student behaviours and institutional conditions that can be promoted in the higher education setting to improve engagement could become more effective in improving student success rates. Their efforts could be further enhanced if students are made aware of how their behaviour, understanding and utilisation of the resources, learning opportunities and services provided by the institution, can positively influence their academic success.

- Description: Like most developing countries, South Africa is characterised by high rates of unemployment in general and even more so among the youth and graduates. One solution to this unemployment problem is encouraging people to become entrepreneurs. Most findings reveal however that entrepreneurial activities among the youth in general and university graduates in particular are low. Since entrepreneurial intention is the main precursor of future entrepreneurial actions, a secondary research was undertaken in this study to discover which factors influence entrepreneurial intention in order to increase students’ future entrepreneurial behaviour. Various determinants of entrepreneurial intention were found in the literature, but none of the previous studies investigated the influence of happiness on entrepreneurial intention, despite the growing importance of research on happiness. Consequently, the primary objective of this study was to identify and empirically test the possible influence of various determinants of students’ Perceived happiness on their Entrepreneurial intention at a higher educational institution in South Africa. The comprehensive literature review that was undertaken revealed eleven independent variables that could potentially influence students’ Perceived happiness. These independent variables were regrouped under two main categories, namely sociodemographic factors and psychological factors. Socio-demographic factors included: Perception of wealth, Satisfaction with health, Perception of employment, Leisure, Social relationships and Religion. On the other hand, psychological factors included: Extroversion, Neuroticism, Optimism, Self-esteem and Goals achievement. The independent variables, the mediating variable (Perceived happiness), as well as the dependent variable (Entrepreneurial intention) were clearly defined and operationalised and a hypothesised model, suggesting the hypotheses between the variables was built. During the creation of the measuring instrument, items were sourced from both reliable and valid scales used in previous studies, as well as self-generated items. The respondents of this study were identified through the simple random sampling technique and an electronic questionnaire was sent to each one of them. In total, 806 usable questionnaires were returned and data was subjected to several statistical analyses. An exploratory factor analysis was conducted to assess the validity of the measuring instrument, whereas reliability was gauged by calculating Cronbach’s alpha coefficients. These two tests allowed the extraction of the dependent variable (Entrepreneurial intention), the mediating variable (Perceived happiness) and seven independent variables, namely Perception of wealth, Perception of employment, Leisure, Religion, Extroversion, Neuroticism and finally Goals achievement. Pearson’s correlation coefficients were calculated in order to assess the degree of correlation or association that existed between the variables investigated in the present study. Multiple regressions analyses were used to test the influence of the independent variables on the mediating variable, whereas simple regression analysis was used to assess the influence of the mediating variable on the dependent variable. Additionally, a series of multiple regression analyses was conducted in order to verify the mediating effect of Perceived happiness between all the independent variables and Entrepreneurial intention. The following independent variables were identified as influencing the mediating variable Perceived happiness, namely: Perception of employment; Leisure; Religion; Extroversion; Neuroticism; and Goals achievement. The results of the series of multiple regression analyses revealed that Perceived happiness had a positive influence on Entrepreneurial intention. However, Perceived happiness did not mediate the relationships between the independent variables and Entrepreneurial intention. Thus, the following independent variables were identified as having a direct influence on the dependent variable Entrepreneurial intention, namely: Perception of wealth; Religion; Perception of employment; Extroversion; and Goals achievement. In order to investigate the influence of various demographic variables on the independent, the mediating and the dependent variables, an analysis of variance (ANOVA) was performed. The demographic variables Gender, Population group, Year of study and Faculty had influences on the dependent variable, Entrepreneurial intention, whereas only Population group and Faculty had influences on the mediating variables, Perceived happiness. By empirically investigating the influence of students’ Perceived happiness on their Entrepreneurial intention, this study has expended the limits of knowledge on both happiness and entrepreneurial intention research. It has made a significant contribution towards understanding the factors influencing students’ Perceived happiness and their Entrepreneurial intention. In addition, practical suggestions and recommendations towards increasing students’ levels of Perceived happiness and aspirations to become entrepreneurs after completing their studies have been proposed to students, lecturers and university management.

- Description: One of the goals for Namibia’s Vision 2030, through ETSIP (2005‐2015), is to establish a preprimary year in primary schools for all children aged 5‐6 to be developed first in schools serving the poorest population and OVCs. ECD is widely recognised as having a significant impact on the subsequent learning of children. The high failure and dropout rate in grade 1 made this process an important one. In 2008 the integration of ECD became a reality in five schools in the Khomas region of Namibia. At present there are 29 pilot schools in the Khomas region 29 schools, and 504 in the whole of Namibia. According to the MoE all primary schools should have a preprimary class as ECD has been recognized as a key contributor to positive outcomes in schools. This study sought to investigate various stakeholders’ experiences and views of the integration of pre‐primary into mainstream pre‐primary schooling. The goal was to investigate the management and leadership implications of this integration. The study is an interpretive case study of three pilot primary schools. The research design made provision for data collection through semi‐structured interviews, focus groups and document analysis. The main finding was that, despite numerous challenges, principals are positive about the integration of pre‐primary. There is a sense of appreciation of the importance of pre‐primary. Principals adopt participative and collegial management approaches in leading their schools towards becoming learning organisations. The study also uncovered several significant challenges, such as the need for more training and the provision of infrastructure to make the process more effective.

- Description: This study examines the topic of the interaction of children’s rights, education rights and freedom of religion in South African schools from a legal perspective. It comprises of a discussion on the historical development of religion in South African schools; South Africa’s international obligations with regards to children’s rights, education rights and freedom of religion and the South African substantive law pertaining to children rights, education and freedom of religion as impacting on legal issues pertaining to religion in schools. The study utilises a desktop approach, which comprises of a wide range of legal and other literary sources, international instruments, statutes and case law on children’s rights, education rights and freedom of religion. Importantly, it highlights the integral connection between these aforementioned rights when dealing with issues pertaining to religion in schools. This thesis illustrates that much of the historical development of religion in schools took place without consideration of children’s rights, or more particularly, the best interests of the learners. Instead, (a particular brand of) religious beliefs were promoted in education above other religions and the well-being of school-children. Furthermore, despite the introduction of specific children’s rights into the Constitution, this thesis emphasises that the rights of children have still not been recognised sufficiently in education laws and policies. It is submitted that children’s rights have a paramount and practical role to play in matters pertaining to religion in South African schools. Consequently, it is recommended that children’s rights, more particularly the best interests of the child principle, should be expressly introduced into education legislation and policies. This will create legal obligations for school administrators and SGBs on the inclusion of children’s rights in religious exemption procedures. Furthermore, it is recommended that national guidelines on religious/cultural exemptions (which incorporate children’s rights) be developed which will set legal parameters for the handling of religious/cultural exemption procedures in schools. This thesis also argues against the interpretation that the right to establish private schools includes the right to require religious conformity from non-adherent learners by way of a complete waiver of their religious freedom. Despite the importance of respecting the right of religious communities to protect and preserve their faith in private schools, it is submitted that this right cannot be exercised without regard for the religious freedom, dignity and best interests of non-adherent children. As a result, it is submitted that the waiver of the freedom of religion of non-adherent children is not consistent with the values which South African society reveres and therefore cannot be enforced. This thesis suggests that there is a way for the rights of private schools and the rights of non-adherent children to co-exist in harmony through the application of the reasonable accommodation principle in private schools. Reasonable accommodation of different faiths teaches religious tolerance to leaners in private schools and ensures that they are prepared to grapple with the religious diversity that they will inevitably face outside of the school environment. It is submitted that the enforcement of reasonable accommodation in private schools is to the benefit of all learners in private schools and to South African society in general. Moreover, this study questions and analyses the state’s provision of compulsory religion education in public schools through the National Policy on Religion and Education. A theoretical distinction is made between religion education and religious instruction in the National Policy itself. Religious instruction refers to the teaching of specific religious beliefs. Religion education refers to the teaching about different religions and worldviews from an academic perspective. It is submitted that the National Policy is correct in removing religious instruction from public schools as this would not be in accordance with freedom of religion or equality rights of learners who are not of the majority faith. It is submitted further that, although the provision of compulsory religion education in public schools impacts upon the freedom of religion of learners and their parents, (if taught correctly) it is a reasonable and justifiable limitation on freedom of religion in that it pursues the legitimate state goal of nation-building through the teaching of religious tolerance and “celebrating diversity” in schools. In light of South Africa’s history of religious discrimination, it must be recognised that the current position (although not problem- free) is a significant step forward in the protection of minority religious rights in South African schools. Despite this, it is submitted that there are numerous problems with the implementation of the National Policy that impact upon the dignity, equality and other rights of the learners concerned. These problems cannot be ignored since they impact upon the daily lives of school children. However, many of these problems can be minimised through more effective teacher training in this subject area. Accordingly, this thesis recommends that the current position be maintained as an acceptable compromise between the two extremes of providing religious instruction in one faith and removing religion education from public schools altogether. However, it emphasises that the state has to make a concerted effort to improve teacher training in this subject area in order to ensure that the objectives of the National Policy are carried out as envisaged. Furthermore, this thesis finds that certain provisions of the National Policy contain not only educational goals, but spiritual goals. Also in some instances, it is difficult to determine whether the religion education curriculum borders on being religious or not. In accordance with freedom of religion, it is submitted that the line between religion education and religious instruction must be clearly drawn in law and in practice. Consequently, the state must reconsider the National Policy and the corresponding religion education curriculum to ensure that they are aligned with the objectives of nation-building in all respects, meaning that any provisions or learning outcomes which have purely spiritual goals- must be amended or removed.

- Description: It has long been accepted that changes in monetary policy have real economic effects; however, the mechanism by which these policy changes are transmitted to the real economy has been the subject of much debate. Traditionally the transmission mechanism of monetary policy has consisted of various channels which include the money channel, the asset price channel and the exchange rate channel. Recent developments in economic theory have led to a relatively new channel of policy transmission, termed the credit channel. The credit channel consists of the bank lending channel as well as the balance sheet channel, and focuses on the demand for credit as the variable of interest. The credit channel is based on the notion that demanders and suppliers of credit face asymmetric information problems which create a gap between the cost of external funds and the cost of internally generated funds, referred to as the wedge. The aim here is to determine the size and lag length effects of changes in credit demand, by both firms as well as households, as a result of changes in interest rates. A secondary, but subordinate, aim is to test for a balance sheet channel of monetary policy transmission. A vector autoregressive (VAR) model is used in conjunction with causality tests, impulse response functions and variance decompositions to achieve the stated objectives. Results indicate that the interest rate elasticity of credit demand, for both firms and households, is interest inelastic and therefore the monetary policy authorities have a limited ability to influence credit demand in the short as well as medium term. In light of the second aim, only weak evidence of a balance sheet channel of policy transmission is found.

- Description: This study investigates the interface between financial and marketing management in South African businesses by investigating the financial and marketing-management processes. This process orientation highlighted important interactions between the two functions. A critical analysis of secondary resources produced a clear theoretical foundation on which the development of the proposed interface framework was based. The critical literature analysis indicates four steps in the financial management process, namely, financial analysis, financial decision-making, financial planning and financial control (independent variables) and five steps in the marketing management process, namely, understanding the marketplace as well as customer needs and wants, designing a customer-driven marketing strategy, constructing an integrated marketing programme, building profitable relationships and capturing value from customers in the form of profits and customer equity. These steps were used to derive a proposed theoretical framework that shows how the steps in the financial-management process relate to those in the marketing-management process. The framework also indicates the perceptions of managers on the interface between the two functions. The perceptions on the interface include aspects such as the level of communication between the two departments, the understanding of each other‟s function and the flow of information between the two departments. From this framework, the six hypotheses were formulated to test the proposed relationships. The focus of the study is on the interface between financial management and marketing management; therefore, the population of this study comprised of financial and marketing managers in South Africa. The primary data relating to the interface between financial management and marketing management was acquired by means of an on-line web-based survey. Descriptive statistics was used to present, analyse and interpret the results of the data analysis. Various inferential statistical techniques (T-tests and chi-squared tests) were employed to determine whether respondents‟ perceptions of the items in the measuring instrument differed as result of whether they were employed in the finance or marketing sections of the business. Correlations (Pearson Product Moment correlations) were calculated for the purpose of investigating the relationships between the financial and marketing management variables used in this study. Factor analysis showed that financial management consisted of four factors that corresponded with the steps in the process, and marketing management produced five factors that related to the steps in the marketing management process. Lastly, statistical tests (MANOVA) were conducted to determine whether the perceptions of respondents, with regard to the financial and marketing management variables, were influenced by selected demographic variables. The results of the empirical study indicated positive relationships between all the variables in the framework. The marketing management factors, namely, mix and profit, reported the lowest correlations compared to the financial management factors. It was also found that financial and marketing managers had different perceptions of the steps in the financial-management process but that they did not have different views of the steps in the marketing-management process. Furthermore, financial and marketing managers had different opinions about the long-term perspective of the business as well as conflicting views with regard to the flow of information from finance to marketing. Financial managers were of the opinion that marketing managers did not understand financial methods and procedures and were unable to specify their requirements to finance. The proposed framework could be seen as the start of marketing theory development on finance interaction as it showed that interface relationships could be further explored.

- Description: Secondary metabolites from natural sources are fast growing as popular drug leads. The structural novelty and favourable biological activity that these compounds display contribute to their popularity as drugs of the future. Examples of such compounds include the potent anticancer drug paclitaxel isolated from the bark of a yew tree as well as the more commonly known analgesic aspirin which stems from the bark of the willow tree. The biological activities exhibited by these secondary metabolites are vast and range from antimicrobial to anticancer activity to mention but a few. As a result, the isolation of novel compounds from natural sources is on the rise. The South African seaboard is home to a wealth of various marine algal species which produce fascinating secondary metabolites. For example, Portierria hornemanii was shown to produce halomon, a halogenated monoterpene which has displayed promising cytotoxic activity. This study thus focused primarily on pursuing novel compounds from three endemic South African marine algal species which have never been analysed previously from a chemical perspective. These are Plocamium rigidum (Bory de Saint-Vincent), Laurencia natalensis (Kylin) and Delisea flaccida (Suhr) Papenfuss. Four known compounds and one new halogenated monoterpene, (2E,5E,7Z)-8-chloro- 7-(dichloromethyl)-4-hydroxy-3-methylocta-2,5,7-trienal, were isolated from Plocamium rigidum. The breast cancer (MCF-7 cell line) inhibitory activity for these compounds was assessed and it was observed that an increase in the lipophilic nature of the compounds produced more favourable IC50 values. A pre-cursor to bromofucin type compounds, cis-laurencenyne, was isolated from Laurencia natalensis, as well as a new acetoxy chamigrane type compound, 4-bromo- 3,10-dichloro-7-hydroxy-3,7,11,11-tetramethylspiro [6.6] undec-1-yl acetate. Delisea flaccida was seen to contain two known bromofuranone type compounds isolated as an isomeric mixture, 1-[(5Z)-4-bromo-5-(bromomethylidene)-2-oxo-2,5- dihydrofuran-3-yl] butyl acetate and 1-[(5E)-4-bromo-5-(bromomethylidene)-2- oxo-2,5-dihydrofuran-3-yl]butyl acetate. These compounds are famous for their ability to inhibit bacterial biofilm production and they have been isolated before from an Australian Delisea spp , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: In South African law, affirmative action has been a very controversial topic over the years. 5 Controversial issues such as perceptions and reactions of affirmative action in the South African context are varied. 6 These reactions are often categorised as politically explosive and emotionally charged. 7 Most people fear the implications of affirmative action, more specifically the impact thereof on their individual positions within the workplace.8 Those who feel threatened by these measures, tend to question the political and ethical legitimacy thereof. 9 Those who stand to benefit from these measures often dislike the labelling associated with these measures. 10 Confusion also exits in greater society about relationship between the equal opportunity, black advancement, affirmative action and diversity management paradigms and related practices. The sources of conflicting reactions to affirmative action stem from individual, group and cultural believes and values which were both shaped by the political realities of the previous regime and the ideals people cherish for themselves in the current dispensation. Colonialist and apartheid laws, policies and practices which were racist and patriarchal provided for separate societies for blacks, whites, Indians and coloureds. 11 At this point in time separate labour systems with job reservation were applicable for whites. There were also wage differentiations between white and black people and between sexes. 12 Furthermore, disabled people were kept dependant and there were also discriminatory legislative provisions against them. 13 This history of systemic discrimination and its resulting inequality and entrenched disadvantage for black, coloured and Indian women and the disabled, was and still is well-known both nationally and internationally. 14 Internationally, apartheid has been extensively disapproved. Examples hereof include the United Nations that declared apartheid and its impact a “crime against humanity” and a negation of the United Nations Charter, 15 expressions of censure culminated in the adoption of the International Convention on the Suppression and Punishment of the Crimes of Apartheid16 and the expulsion of South Africa from the United Nations and its agencies. 17 Nationally, on the other hand, South Africa promulgated several legislative pieces namely, the Constitution, the Promotion of Equality and Prevention of Unfair Discrimination Act 4 of 2000 and the Employment Equity Act 55 of 1998.

- Description: In South African law, affirmative action has been a very controversial topic over the years. 5 Controversial issues such as perceptions and reactions of affirmative action in the South African context are varied. 6 These reactions are often categorised as politically explosive and emotionally charged. 7 Most people fear the implications of affirmative action, more specifically the impact thereof on their individual positions within the workplace.8 Those who feel threatened by these measures, tend to question the political and ethical legitimacy thereof. 9 Those who stand to benefit from these measures often dislike the labelling associated with these measures. 10 Confusion also exits in greater society about relationship between the equal opportunity, black advancement, affirmative action and diversity management paradigms and related practices. The sources of conflicting reactions to affirmative action stem from individual, group and cultural believes and values which were both shaped by the political realities of the previous regime and the ideals people cherish for themselves in the current dispensation. Colonialist and apartheid laws, policies and practices which were racist and patriarchal provided for separate societies for blacks, whites, Indians and coloureds. 11 At this point in time separate labour systems with job reservation were applicable for whites. There were also wage differentiations between white and black people and between sexes. 12 Furthermore, disabled people were kept dependant and there were also discriminatory legislative provisions against them. 13 This history of systemic discrimination and its resulting inequality and entrenched disadvantage for black, coloured and Indian women and the disabled, was and still is well-known both nationally and internationally. 14 Internationally, apartheid has been extensively disapproved. Examples hereof include the United Nations that declared apartheid and its impact a “crime against humanity” and a negation of the United Nations Charter, 15 expressions of censure culminated in the adoption of the International Convention on the Suppression and Punishment of the Crimes of Apartheid16 and the expulsion of South Africa from the United Nations and its agencies. 17 Nationally, on the other hand, South Africa promulgated several legislative pieces namely, the Constitution, the Promotion of Equality and Prevention of Unfair Discrimination Act 4 of 2000 and the Employment Equity Act 55 of 1998.

- Description: This paper is divided into two distinct sections. The first being an analysis of the legal protection of temporary employees as things currently stand. It deals with the various labour laws that currently regulate temporary employment as well as the temporary employment contract and the common-law. The second section summarises and analyses the provisions of the Labour Relations Amendment Bill and the Basic Conditions of Employment Bill as they apply to fixed-term employees. Temporary employees are protected by the general protection extended to all employees in terms of section 23(1) of the Constitution of the Republic of South Africa, 1996, guaranteeing all employees the “right to fair labour practice”. The Labour Relations Act has as one of its main objectives to give effect to and regulate the fundamental rights contained in the Constitution. Thus the Labour Relations Act must not only give effect to constitutional rights but it must also ensure that it in no way unreasonably or unjustly denies or limits constitutional rights. Temporary employees have a number of labour laws protecting their interests. Where the provisions of the Basic Conditions of Employment Act, a Bargaining Council Agreement or a Sectoral Determination do not apply the employee will rely on the terms of the fixed-term employment contract and thereafter the common law for protection. The only protection offered to temporary employees contained in the Labour Relations Act is in section 186(1)(b), where a dismissal is defined to include the non-renewal of temporary contracts of employment where there is a reasonable expectation of renewal on the same or similar terms. This provision has proved to be highly controversial in that it does not expressly cater for temporary employees who harbour reasonable expectations of indefinite employment. An analysis is made of the most important cases relating to section 186(1)(b). The second section unpacks and critically analyses the Labour Relations Amendment Bill and the Basic Conditions of Employment Bill which have been long in the offing and when they are finally enacted, will bring with them sweeping changes for atypical employment . The amendments will drastically change the way employers make use of fixed-term employees as well as the way in which Temporary Employment Services may conduct business if they are in fact able to keep working at all. There is very little literature of substance written about the Labour Relations Amendment Bill as it applies to atypical employment. The fact that the proposed amendments have changed so many times over such a long period of time might have deterred many writers from investing time and effort in attempts to analyse and summarise the amendments. Articles posted on the internet are in the main short and have very little content. No books were found with any discussion that pertains to the amendments. The amendments divide employees involved in atypical employment into two different categories. These categories consist of employees earning above the threshold in terms of section 6(3) of the Basic Conditions of Employment Act and those earning below this threshold. All fixed-term employees may rely on the provisions of section 186 of the Labour Relations Act. Employees earning below the threshold are considered to be the most vulnerable and have been afforded additional protections in terms of sections 198(A), (B) and (C).

The limitations and possiblilites of identity and form in selected recent memoirs and novels by white, female Zimbabwean writers : Alexandra Fuller, Lauren Liebenberg

- Description: This study examines selected works by four white female Zimbabwean writers: Alexandra Fuller, Lauren Liebenberg, Bryony Rheam and Lauren St John, in light of the controversy over the spate of white memoirs which followed the violent confiscation of white farms in Zimbabwe from 2000 onwards. The controversy hinges on the notion that white memoir writers exploit the perceived victimhood of white Zimbabweans in the international sphere, and nostalgically recall a time of belonging – as children in Rhodesia – which fails to address the fraught colonial history which is directly related to the current political climate of the country. I argue that such critiques are too generalised, and I regard the selected texts as primarily critical of the values and lifestyles of white Rhodesians/Zimbabweans. The texts I have selected include a range of autobiographical and fictional writing, or memoirs and pseudo-memoirs, and I focus on form as a medium enabling an exploration of identity. The ways in which these authors conform to and adapt particular narratives of becoming is examined in each chapter, with a particular focus on the transition from innocence to experience, the autobiography, and the Bildungsroman. Gender is a recurring point of interest: in each case the female selves/protagonists are situated in terms of the family, which, in reflecting social values, is a key site of conflict. In regard to trends in white African writing, I explore the white African (farm) childhood memoir and the confessional mode. Ultimately I maintain that while the texts may be classified as white writing, as they are fundamentally concerned with white identity, and therefore evince certain limitations of perspective and form, including clichéd tendencies, all the writers interrogate white identity and the fictional texts more self-reflexively deconstruct tropes of white writing.

- Description: Whenever two or more people from different cultures interact in an educational environment learning and teaching can be affected either positively or negatively. The study sought to establish the link between intercultural differences and optimal teaching and learning environments. The aim of the study was therefore to enhance teaching and learning environments through improved intercultural understanding. The research was based on the qualitative approach. The research design that was used in the execution of the study was a case study. The data collection methods that were used were focus group discussions, interviews and observation. The study found that there are some intercultural experiences that either enhance or inhibit educational equality and quality. These are medium of instruction (English Language), availability and accessibility of learning resources and parental support. It was also concluded that acts of discrimination alone cannot affect the performance of learners but, rather, a combination of other intercultural influences play a role. Moreover, the study found that language can be used as a tool to promote respect for humanity as it was singled out as one of the factors that inhibit respect for others. In promoting tolerance towards each other, the study found that negative self-esteem, seen mostly with the under privileged learners, affects negatively their ability in tolerating each other. In addition, encouraging participation of learners in sport and group activities emerged as some of the pursuits that can promote tolerance amongst learners from different cultural backgrounds. The strategies to enhance optimal teaching and learning that were revealed by the study are: repetition of lessons by teachers; motivating and appreciating learners; monitoring classroom dynamics; creating social clubs; training teachers on cultural diversity (inclusive of communication); acknowledging, valuing and celebrating cultural differences; declaring English as an elective subject; unlimited access to the internet and library; and promoting parental involvement in the education of their children.

Contextual, exploratory, descriptive qualitative research based on a phenomenological approach was conducted and analysed through interpretative phenomenological analysis (IPA). A combination of purposive and snowball sampling was used to recruit participants and semistructured in-depth interviews were conducted with four South African adult, black, Xhosaspeaking females of homosexual orientation between the ages of 18 to 35 years. Findings indicate that the participants experience the following: (a) sexual development as a major influence on their sexual- and self-identity, (b) homosexual sexual orientation had a psychological impact on their lives, (c) they have a holistic understanding of who they are, and this understanding of themselves, has positively influenced their lives, (d) their homosexual sexual orientation has influenced the personal relationships in their lives in both positive and negative ways, (e) society has influenced their lives both positively and negatively because of their homosexual sexual orientation , (f) social networking can act as a risk to unintentional disclosure of homosexual sexual orientation and (g) they have experienced discrimination in various areas of their lives because of their homosexual sexual orientation. Some suggestions for future research included exploring lesbian stereotypes within the broader society, as well as inside the black lesbian community and examining the so-called differences between city and township lesbians with an emphasis on beliefs, attitudes, practices, subcultures and gender identity issues.

- Description: This research study has emerged as a result of my concern regarding many of my colleagues’ apparent low morale in the teaching profession. Since the new dispensation in 1994 the South African education system has undergone numerous and intensive curriculum changes as varying policies aimed at transforming education in South Africa have been implemented (Asmal, 2009). I, therefore, decided to investigate the lived experiences of Intermediate Phase teachers regarding curriculum renewal processes in South Africa over a fifteen year period from 1998 to 2012. This period encompasses the four curriculum renewal processes which have been implemented since 1994. The research undertaken was an empirical study and qualitative methods were used for data gathering purposes. Data collection tools included unstructured, individual, in-depth interviews and reflective journal entries. The qualitative data generated suggest that many teachers in the Port Elizabeth Metropole appear to be demotivated by the uncertainty around curriculum renewal and the impact this has on curriculum implementation in their respective classrooms. According to Ornstein and Hunkins (2004), the implementation process of a new curriculum requires extensive actions by the designers and implementers of the new programme and Smith (2008) asserts that managing change in education, and improvement in classroom instruction, are very complex tasks which teachers and learners face worldwide. The study revealed that the main obstacles to successful curriculum change initiatives are insufficient training of teachers, lack of support for teachers and time constraints under which teachers work. An investigation into the lived experiences of teachers regarding the post- apartheid curriculum renewal processes should make a valuable contribution to the debate in terms of providing insights for curriculum implementers of possible alternative curriculum implementation strategies for more effective curriculum renewal processes in the future.

- Description: Professional nurses working in an intensive care unit (ICU) are faced with the death of critically ill patients frequently. Modern day medicine and technology have made it possible for advanced life-sustaining measures to be implemented on patients who, without medical intervention, would otherwise not have survived. The question is raised: is modern technology preserving life and prolonging the dying process, or is it in the best interest of the patient for treatment to be withdrawn? Nurses, caring for these patients and their families, are practicing at the bedside of these dying patients and are thus often faced with end-of-life issues, particularly withdrawal of treatment. The primary functions of critical care nurses are toward their patients. Physicians are responsible for making decisions regarding withdrawal of treatment. However, the nurses in the ICU are responsible for implementing the decisions made; sometimes contradicting what they believe in. The experience of end-of-life issues, namely withdrawal of treatment, is a cause of distress for the professional nurse. Little research has been done on how the ICU nurses deal with end-of-life issues and what support structures are required to assist nurses in dealing with end-of-life issues (Hov, Hedelin & Athlin, 2006:204) The objectives of the study were to explore and describe the professional nurses‟ lived experiences of end-of-life issues in the intensive care unit. The study aimed to make recommendations regarding support strategies to assist professional nurses in dealing with end-of-life issues in the intensive care unit. The researcher has selected a qualitative research approach with an explorative, descriptive and contextual design in order to conduct the study. Data was collected by means of semi-structured interviews. Data was analysed using the steps as illustrated by Tesch‟s method. Ethical principles were maintained throughout the research study. The findings of this study are to be presented in a journal publication.

The question is raised: is modern technology preserving life and prolonging the dying process, or is it in the best interest of the patient for treatment to be withdrawn? Nurses, caring for these patients and their families, are practicing at the bedside of these dying patients and are thus often faced with end-of-life issues, particularly withdrawal of treatment. The primary functions of critical care nurses are toward their patients. Physicians are responsible for making decisions regarding withdrawal of treatment. However, the nurses in the ICU are responsible for implementing the decisions made; sometimes contradicting what they believe in. The experience of end-of-life issues, namely withdrawal of treatment, is a cause of distress for the professional nurse. Little research has been done on how the ICU nurses deal with end-of-life issues and what support structures are required to assist nurses in dealing with end-of-life issues (Hov, Hedelin & Athlin, 2006:204) The objectives of the study were to explore and describe the professional nurses‟ lived experiences of end-of-life issues in the intensive care unit. The study aimed to make recommendations regarding support strategies to assist professional nurses in dealing with end-of-life issues in the intensive care unit. The researcher has selected a qualitative research approach with an explorative, descriptive and contextual design in order to conduct the study. Data was collected by means of semi-structured interviews. Data was analysed using the steps as illustrated by Tesch‟s method. Ethical principles were maintained throughout the research study. The findings of this study are to be presented in a journal publication.

- Description: The supply of Antiretrovirals (ARVs) to HIV/AIDS patients in most of the provinces in South Africa is hindered by various factors such as ineffective and inefficient drug procurement, and drug distribution systems. In the QwaQwa district in the Free State Province, a major barrier to the consistent supply of Highly Active Antiretroviral Treatment was identified to be the lack of an effective and efficient ARV drug distribution system. This resulted in major drug supply shortages in the QwaQwa district. A continuous, uninterrupted supply of ARVs to HIV/AIDS patients is critical to avoid drug resistance and therapy failure. Failure of a patient to respond to treatment results in a deterioration of a patient's health, and ultimately leads to death. The purpose of the study was to determine whether the ARV drug distribution practices at the Manapo Hospital in the QwaQwa district were effective and efficient in the management of ARVs. The distribution practices reviewed were the ordering, transportation, the management of inventory and warehousing, and the distribution of treatment to HIV/AIDS patients. Quantitative exploratory, descriptive and contextual methods were used to determine the relationship between the ARV drug distribution practices and the effective management of the ARVs. The study comprised of a sample size of twenty-one participants. The sample size entailed the Manapo Hospital pharmacists and pharmacist assistants who have been or are currently involved in the distribution of ARVs in the QwaQwa district since the initiation of the ARV rollout programme in 2004. The study revealed that the practices performed in the management of ARVs in the QwaQwa district were neither effective nor efficient in the distribution of ARVs. The recommendations of the study were identified to further ensure the effective and efficient management of the ARV drug distribution system, which will ensure a consistent supply of treatment to HIV/AIDS patients. Guidelines were developed for better circulation, thus meeting the objectives of the research.

- Description: Community participation in urban renewal projects has become important in the South African government’s efforts to address past imbalances and improving the livelihoods of socially excluded and marginalised communities. In order for the Helenvale Urban Renewal Project to be successful and bring about sustainable change, it is vital that the community be allowed and encouraged to play an active role in consultation and participation initiatives. This study outlines the importance of community participation, the types, the incentives and disincentives as well as the possible barriers to effective community participation. Findings from the analysis of the collected data indicates that a community project can only be successful if the implementing agent employs democratic principles whereby all residents are given a voice and are allowed to participate in the decision-making and implementation process. This study explores the concept of community participation in the Helenvale Urban Renewal Projects with particular reference to the role played by the Mandela Bay Development Agency in promoting community participation in the Helenvale Urban Renewal Projects (HURP), in Port Elizabeth.

- Description: Obesity can lead to Type 2 Diabetes, both conditions increase in association with physical inactivity and high-energy diets, resulting in elevated blood glucose, decreased insulin sensitivity and increased insulin resistance. Sutherlandia frutescens (S.frutescens), an anti-diabetic plant, reverses and prevents insulin resistance in a rat model and human cell culture model. Gene expression analysis in hepatocyte cultures, identified genes down regulated in insulin resistance and up regulated by S.frutescens. These included genes encoding vesicle transporter proteins, hypothesised to be linked to hepatic lipid accumulation and lipid droplet formation during insulin resistance. The aim of this study was to investigate critical genes involved in lipid droplet formation, vesicle assembly and transport in high fat diet (HFD)-induced insulin resistant rat liver tissue during the development of insulin resistance and the reversal of these changes by S.frutescens. Rats were fed a low fat diet (LFD) or HFD supplemented with S.frutescens for 2, 4 and 8 weeks. Rats fed a HFD for 12 weeks developed insulin resistance, confirmed by plasma glucose and insulin levels (compared to normal controls). Groups of these rats were gavaged with S. frutescens (50mg/kg BW), Metformin (13mg/kg BW) or water for a further 4 weeks and starved for 12 hours, anaesthetized and blood removed by heart puncture. Liver was stored in RNA-Later™ for qRT-PCR and snap-frozen in liquid nitrogen for western blotting and confocal microscopy analysis. Changes in expression of vesicle transporter genes VAMP3 and NSF were analysed by qRT-PCR and changes in the protein expression by western blotting analysis. Proteins were localised within the liver by confocal immunohistochemistry using ZEN lite™ software. Statistical analysis was performed using One-Way ANOVA and unpaired t-test. mRNA gene expression of vesicle transport components VAMP3, NSF and SNAP25 showed relatively moderate changes with considerable individual variation within control or experimental groups. Uncorrelated changes in mRNA and protein products were found and may be due to differential regulation by siRNA. Proteins also showed altered staining patterns in high fat diet rats that reverted towards normal on S. frutescens treatment, potentially reflecting functional changes associated with transport of lipid-filled vesicles.
