  • Description: A middle-aged woman, living in Johannesburg, has an experience which catapults her into changing her life. In the process of confronting her alcoholism, she realizes how patterns of addiction extend to other areas of her life and tries to make sense of the tragic events that have occurred. Her world becomes a different place as she questions everything that she has been taught about relationships, religion, race and her place in society. In the search for answers she uncovers stories about the lives of her parents, grandparents, relatives, friends and acquaintances. Embarking on a journey of discovery and rediscovery through her experiences and those of others, she explores the ways in which the things that she thought she knew defined her behaviour and expression of herself.

  • Description: The study reported in this thesis investigated Emirati students’ claims related to experiences of cultural bias of the reading component of the IELTS examination through a critical realist lens. Critical realism posits a layered reality which allows for the conceptualization of experiences as emerging from the interplay of events and mechanisms found in two other realms of reality – the actual and the real. Experiences, therefore, have a different ontological status than the events and the causal mechanisms to which they are attributed. Social realism was used to further explore the depth of the realm of the real through Archer’s construct of analytical dualism. This allowed for the placement of generative mechanisms into three domains: structure, culture, and agency. There were two parts to this investigation: a content analysis and a focus group study. The first part of the content analysis consisted of analyzing 60 reading passages from 20 IELTS examinations for a number of cultural categories. These included such things as cultural objects, social roles, idiomatic expressions, traditions and festivals, superstitions and beliefs, and political and historical settings. The second part of the content analysis focused on the question types and syntactical structure of the 5 different IELTS examinations that the focus groups students sat. All three components of the analysis – the cultural content, question types, and syntactical structure – were conducted at the level of the actual. Findings indicated that on average, an IELTS examination contained 14 cultural references of various kinds. Only 4% of all geographical references pertained to the Middle East with the biggest share being western locations. The most common question types were matching questions, fill in the blank questions, and yes/no questions with more than 50% of all questions requiring some form of higher order thinking due to text reinterpretation. The study also found that the question types were not consistently distributed over the examinations with each consisting of a different variety of questions and some even having repetitive question types on one reading examination. The second part of the study was the focus groups. Here, 21 Emirati students sat 5 different IELTS examinations. Upon test completion, these students underwent a semistructured interview to relate their experiences of the test. These experiences, at the level of the empirical, all shared 7 ideas: reading is hard, the questions are too difficult, the passages are too long and difficult, the topics are unfamiliar, the topics are not interesting, the vocabulary is too difficult, and there is not enough time. When the processes of retroduction and abduction were applied to both the content analysis and these common experiences, numerous structures and discourses at the level of the real were identified as having contributed to the emergence of the feeling of bias at the level of the empirical. These structures included such things as the students’ school system (eg. curriculum, assessment, instructors etc.), religion, literacy practices, and home. In the cultural domain, a number of discourses were found to contribute to the experiences at the level of the empirical. Amongst these were the ‘Unimportance of Reading’, the culture of ‘Obedience’, the rejection of the ‘un-Islamic’, and the students’ sense of ‘Entitlement’.

  • Description: This study looks at the curriculum outcomes, teaching practices and learner competencies in isiXhosa at three Eastern Cape schools and across three different grades, 7-9. It explores the link between language learning and teaching as well as the teaching strategies used within the classroom. In particular, the study seeks to analyse how isiXhosa is taught at three different levels of instruction, namely at Home Language (HL), First Additional Language (FAL) and Second Additional Language (SAL) levels. Qualitative methods were used, and the study took the form of interpretive case studies within the respective schools. The purpose of using multiple case studies was to investigate the reality within the three sites selected. The three schools had three extreme settings, in the sense that one of the schools is a rich isiXhosa environment and the other two schools are English environments. The tools used for data gathering were interviews, classroom observations, and an analysis of documents from the Department of Basic Education. Data was then presented and analysed in Chapter 4 and 5 against the backdrop of an extensive literature review in Chapter 2 as well as a detailed methodological approach as outlined in Chapter 3. One of the findings of this research indicates that in two of the schools the teaching culture is largely from a western perspective, whereas in one of the schools the learners are primarily isiXhosa speaking and teachers use a different linguistic approach to imparting knowledge. In the private and ex-Model C school it was found that a lack of exposure to isiXhosa is the primary cause of language problems for L2 learners. Secondly the L1 is not appropriately maintained or promoted in the school environment because it is presumed that learners are sufficiently exposed to their L1 at home. The research found therefore that in this particular schooling environment there is an inconsistency between the curricula that is taught in relation to the linguistic abilities of the learners, many of whom are mother tongue speakers of isiXhosa. Furthermore and more generally, it was found that teachers are still not well informed concerning South Africa’s Language-in-Education-Policy and there is a need for more inservice training that will focus on the nature of additional language acquisition in order to address the challenges of teaching these languages. The thesis concludes that extensive work needs to be done in order to reposition the teaching of isiXhosa at all three levels, but particularly at FAL level. This research shows that there is a disjuncture between the proposed curriculum/learning outcomes and the standards or levels achieved by the learners, more especially at FAL and SAL where oral proficiency in isiXhosa remains a challenge. Specific recommendations are contained in the final chapter of the thesis which also makes reference to the draft policy of the Ministry of Basic Education regarding the incremental introduction of the teaching of African languages from 2014 onwards. This thesis also makes takes as a point of departure the importance of multilingualism in a multicultural society such as South Africa where language is suggested as a strong factor in the fostering of social cohesion. It is for this reason that the thesis argues that the expert teaching of African languages, in this case isiXhosa, at both mother tongue and second language levels is of fundamental importance to the future of South African society.

  • Description: The role of entrepreneurship in small to medium tourism enterprises is well recognised and acknowledged as a significant contributor to economic development and employment opportunities. Worldwide, small to medium tourism enterprises play a dominant role in the tourism industry. These businesses are often vulnerable to external economic forces and find it increasingly difficult to transform their strategic and operational management to face the challenges placed upon them. This study focuses on small to medium tourism enterprises in the Eastern Cape Province, which is economically the poorest province of South Africa. To ensure the growth and sustainability of small to medium tourism enterprises, owners need to make efficient and effective business decisions regarding the challenges their businesses face. The study examines the factors impacting customer relationship management in the context of small to medium tourism enterprises in the Eastern Cape. Customer relationship management, that is, building relationships with customers, has become of pivotal importance to many organisations as businesses strive to be competitive and profitable. While large organisations practice customer relationship management to enable them to better target profitable customers, improve customer services, enhance customer retention and ultimately improve business performance, small businesses often need assistance in understanding and effecting this complex relationship. The factors that could impact customer relationship management in the organisations are the focus of this study. Three major factors were identified, namely, strategic, operational, and organisational factors. The study furthermore examined the extent to which these factors are present in the tourism and hospitality sector of the Eastern Cape and investigated the relationships between these factors. Quantitative research was deemed appropriate for this study. Systematic random sampling was employed to select a sample of 332 respondent organisations from the 2012 database of the Eastern Cape Parks and Tourism Agency consisting of formally registered small to medium tourism enterprises. A total of 310 usable questionnaires were finally obtained. Both descriptive and inferential statistics were used in the study. Descriptive statistics were computed to reflect the organisations‟ and respondent managers‟ general characteristics and to summarise their measurement scores. Using inferential statistics, the study further investigated relationships between customer relationship management factors, as well as demographic factors. Data were subjected to exploratory factor analysis and both the validity (refer to section 2.10.1) and reliability (refer to section 2.10.2) of the research instrument was assessed. The relationships between customer relationship management variables were also investigated (refer to section 2.11.4). The research results support an overall significant association between customer relationship management readiness and business strategy, customer strategy, touch points and competencies, skills and technology. Relationships were also explored among customer relationship management factors and demographic characteristics. Significant results were found between perceived business performance and the gender of managers, family businesses and gross annual turnover. The most salient contributions of this research can be summarised as follows. The overview of the importance of tourism and the role of small to medium enterprises in the tourism and hospitality industry of the Eastern Cape will benefit researchers and potential owners who have an interest in this sector. The study contributes to an improved understanding of the factors that should precede customer relationship management. The study established a profile of the small to medium tourism enterprises in the Eastern Cape which can serve as a basis for future research. A measuring instrument for assessing respondents‟ views on the existence of the strategic, operational and organisational factors in their organisations was developed. This instrument showed good internal validity and reliability and can serve as a basis for the same purpose in contexts other than the tourism and hospitality sector. This research has made a contribution toward a largely under-researched area concerning customer relationship management in small to medium enterprises. Recommendations for managers and consideration of future research included the following. Managers need to have a strategic vision and a strong customer-centric focus. Through understanding customers and their needs, offerings can be tailored to maximize the overall value of customers, thereby, improving business performance. Through efficient operational processes in place, enhanced customer service levels can be attained in the organisations. Managers need to effectively manage customer information through data warehousing and technology. Top management commitment is a crucial element for ensuring improved customer services. Managers need to train staff with respect to customer services, thus enhancing CRM. Future researchers can conduct a longitudinal study and investigate the same factors which could impact customer relationship management. A verification of the usefulness of the measuring instrument in examining the determinants of customer relationship management and the level of development regarding other small businesses is suggested. It is recommended that this study be replicated abroad in an effort to verify to what extent the determinants of customer relationship management are evident in small businesses of other countries.

  • Description: Retail industry in South Africa is witnessing fast growth in all cities in South Africa. Attracting customers become key to success in the increased industry competition. Keeping customers satisfied has never been more important than currently. Retailers need to know what customer needs and wants are, to be able to provide and constantly satisfy their needs. Growth in the industry is largely influenced by economic conditions. A stable economic environment allows customers to spend more, thereby increasing the value of retail trade sales. In South Africa, there is strong competition between the four major dominant firms in the retail industry, which include Pick n Pay Holdings Limited (30%), Shoprite Holdings Limited (34%), Spar Holdings Limited (24%), and Woolworths Holdings Limited (11%). For the firms to grow in South Africa, they must have a clear understanding of consumers’ needs and wants. Services rendered by retailers are of utmost importance to their level of success and ability to successfully cater for the market’s needs. The main purpose of this study is to investigate customer satisfaction of two retail stores in the Nelson Mandela Bay, namely Summerstrand and Cleary Park Pick n Pay stores. Three independent variables (employee empowerment, technology and customer relations) were identified and were tested against one dependent variable (customer satisfaction). A positivistic paradigm was used to conduct the research. The approach uses the quantitative method of research to establish the causal relationships. A null (Ho) and alternative (Ha) hypotheses were formulated in order to test relationships between variables. A five-point Likert scale enabled primary data to be sourced for 294 customers’ (respondents), who shared their customer satisfaction experience at Pick n Pay stores in the Nelson Mandela Bay. A statistical analysis of quantitative data compromised of three phases. Firstly, the data was subjected to a descriptive analysis to summarise the data. Secondly, reliability (internal consistency) for the research instrument was assessed by means of the Cronbach Alpha Reliability Coefficient. Finally, multiple linear regression analysis were used to test the hypothesis. The empirical findings show that the independent variable positively correlated with the dependent variables. This implies that a positive relationship between employee empowerment, technology, customer relations and customer satisfaction at Pick n Pay stores. Therefore, recommendations given by the researcher focused on all variables that have a relationship with customer satisfaction.

  • Description: Background: Elephantorrhiza elephantina (Ee) and Pentanisia prunelloides (Pp) are two medicinal plants which are widely used to remedy various ailments including diarrhoea, dysentery, inflammation, fever, rheumatism, heartburn, tuberculosis, haemorrhoids, skin diseases, perforated peptic ulcers and sore joints in southern Africa (South Africa, Swaziland, Botswana and Zimbabwe). The following study was conducted to explore the in vitro cytotoxicity, antioxidant properties and phytochemical profile of the two medicinal plants. Materials and Methods: The cytotoxicity of the aqueous and methanol extracts and fractions of both species was studied using the brine shrimp lethality tests (BST) for the first time. Results: The results demonstrated that the lethality (LC50) for crude extracts for both plants ranged between 1.8 and 5.8 ppm and was relatively greater than that for the methanol, ethyl acetate and chloroform fractions of the extracts which ranged between 2.1 ppm and 27 ppm. This suggested that crude extracts were more potent than their respective fractions, further explaining that the different fractions of phytochemicals in these plant species work jointly (in synergy) to exert their therapeutic efficacy. Both aqueous and methanol extracts of the two medicinal plants demonstrated a high degree of antioxidant capacity against the DPPH radical with the Duh and Yen inhibition percentage ranging between 4.5% and 72%. Phytochemical studies of the rhizome extracts showed that the major compounds present include flavonoids, tannins, anthocyanidins, anthraquinones, triterpenoids (oleanolic acid), the steroidal saponin Diosgenin, the sugars, rhamnose, glucuronic acid, Arabinose and hexoses. Conclusion: This is the first report of the detection and isolation of diosgenin and oleanolic acid from the rhizome extracts of Ee and Pp. All structures were determined using spectroscopic/spectrometric techniques (1H NMR and 13C and LC-ESI-MS) and by comparison with literature data.

  • Description: This thesis argues that there is a clear imbalance in the representation of crime in the newspaper, Grocott’s Mail, in Grahamstown, in the Eastern Cape of South Africa. The thesis concludes that the system of marginalisation and segregation which was established during the apartheid era is the foundation for the continued segregation and marginalisation of certain groups of people in Grahamstown as depicted in crime journalism. Previous research shows that not only people, but spaces are marginalised through media representations of crime. As people are represented as dangerous, so too the spaces they occupy become dangerous spaces. Importantly, the research shows that discourses of marginalisation are present in newspaper reports reproducing the discourses prominent in society, and in turn, the newspaper itself perpetuates these marginalising discourses. This extends into the coverage that different crimes receive in newspapers. For instance, the reports show that a middle-class audience will be more concerned with property crime in middle-class neighbourhoods, than other crimes in lower-class neighbourhoods. I argue that not only the type of crime, but the severity, the effect, and the necessity for justice represented by the newspaper, are all largely determined by the region of the crime. Further, I show that the criminal is not only demonised and represented as individually deviant in the reports in the newspaper, but that these representations are made by this newspaper because they are deeply imbedded as a discourse in society. This is partly because this newspaper has taken on a monitorial role, requiring neutral reporting from journalists, and a dedication to surveying the processes of state institutions, like the police and courts. As a result, the ways in which crime is reported on in the newspaper is fairly well fixed, making it difficult for journalists to conceive of different ways of reporting crime. The representations of the criminal justice system that the monitorial media, this newspaper included present, are a careful balance between the interest of the public, and the need to preserve relationships with sources. The monitorial media in general, and this newspaper in particular, represent the criminal justice system. The relationship between the police and the newspaper, and the courts and the media, therefore strongly influences the way in which crime news is reported. In particular, crime news is represented from the perspective of the criminal justice system. This research was carried out using Critical Discourse Analysis, qualitative interviews, and focus group interviews.

  • Description: Data-centric security is significant in understanding, assessing and mitigating the various risks and impacts of sharing information outside corporate boundaries. Information generally leaves corporate boundaries through mobile devices. Mobile devices continue to evolve as multi-functional tools for everyday life, surpassing their initial intended use. This added capability and increasingly extensive use of mobile devices does not come without a degree of risk - hence the need to guard and protect information as it exists beyond the corporate boundaries and throughout its lifecycle. Literature on existing models crafted to protect data, rather than infrastructure in which the data resides, is reviewed. Technologies that organisations have implemented to adopt the data-centric model are studied. A utopian model that takes into account the shortcomings of existing technologies and deficiencies of common theories is proposed. Two sets of qualitative studies are reported; the first is a preliminary online survey to assess the ubiquity of mobile devices and extent of technology adoption towards implementation of data-centric model; and the second comprises of a focus survey and expert interviews pertaining on technologies that organisations have implemented to adopt the data-centric model. The latter study revealed insufficient data at the time of writing for the results to be statistically significant; however; indicative trends supported the assertions documented in the literature review. The question that this research answers is whether or not current technology implementations designed to mitigate risks from mobile devices, actually address business requirements. This research question, answered through these two sets qualitative studies, discovered inconsistencies between the technology implementations and business requirements. The thesis concludes by proposing a realistic model, based on the outcome of the qualitative study, which bridges the gap between the technology implementations and business requirements. Future work which could perhaps be conducted in light of the findings and the comments from this research is also considered.

Degradation of Paracetamol and other constituents in Perfalgan®: subtitle if needed. If no subtitle follow instructions in manual

  • Authors: Curran,Catherine

  • Description: Abstract text. 5.1 Background Paracetamol (acetaminophen) is useful for the treatment of mild to moderate pain as well as being opiate–sparing. In recent years the problem of poor solubility of paracetamol in water has been overcome and an intravenous formulation of paracetamol developed. In South Africa this is marketed by Bristol-Myers Squibb as Perfalgan®. Each 500 mg or 1g ampoule of Perfalgan® is recommended for single use only and is to be discarded once opened (Medicines.org, n.d.). This is most likely due to concerns about degradation of paracetamol or other ingredients in the solution once exposed to air and sterility issues. However in South Africa where this drug is expensive, some centers use one ampoule for multiple cases over the course of 12-24 hours. No obvious clinical adverse effects have been reported. 5.2 Objective of study The aim of this study was to examine the practice of using a single vial of Perfalgan® in divided doses over the course of a day for different patients by way of assessing the stability of Perfalgan® on exposure to air. The study has three components, namely: 1. In vitro assessment of paracetamol levels on exposure to air and stressors over time. 2. In vitro assessment of levels of the excipients, namely mannitol and cysteine on exposure to air and stressors over time. 3. Assessment of the lipid permeability of paracetamol in Perfalgan® on exposure to air and stressors over time. C Curran 2014 Degradation of paracetamol and other constituents in Perfalgan® 8 5.3 Methodology High performance liquid chromatography (HPCL-UV) was used to determine the concentration of paracetamol and the presence of degradation products in samples taken at set time periods following exposure of Perfalgan® to air and stressors. Initial work was done using pure paracetamol to determine optimal measurement conditions prior to analysing Perfalgan®. The concentrations of the additives and their degradation products were measured using nuclear magnetic resonance (1 H NMR). Appreciable changes in these could indicate a safety hazard or decreased bioavailability. Finally ultraviolet spectroscopy was performed to assess samples at a wider spectrum of wavelengths, instead of the single wavelength used in HPLC. This was used to assess for degradation products which absorb at different wavelengths and therefore may be missed if HPLC was used alone. Ultraviolet spectroscopy was also used to test bioavailability of the drug via the octanol:water partition coefficient under stressed and unstressed conditions. 5.4 Results The paracetamol in Perfalgan® did not degrade on exposure to air over 24 hours. Neither did it degrade on exposure to acid, alkali, oxidative or heat stress. The HPLC retention time was constantly between 3.17-3.29 minutes. 1 H NMR revealed no change in the formulation of Perfalgan® except for the conversion of the oxygen scavenger cysteine to cystine. The octanol:water partition coefficient likewise stayed constant and was in agreement with the value of 0.46-0.49 quoted in the literature (International Programme on Chemical Safety, 2008; McNeil Consumer Healthcare, 2010). 5.5 Conclusion The paracetamol in Perfalgan® did not degrade on exposure to air and other stressors over 24 hours. The formulation as Perfalgan® was likewise found to be stable. The drug retained its lipid permeability over this period. , Thesis (MMED) -- Faculty of Health Sciences, 2014

  • Description: Publisher version , This paper examines dependence on environmental resources and impacts on household welfare among the indigenous San and Mier rural communities neighbouring Kgalagadi Transfrontier Park in South Africa. Data on the various household income types, including environmental income, were collected through a structured survey of 200 households. Environmental income constituted 20% of the total income. The poorest income quintile showed the highest relative dependence on environmental income (31%), though absolute environmental income increased with total income. Poverty analyses showed that poverty incidence and poverty gap would increase by 13 and 7 percentage points respectively without environmental income. Gini-coefficient analyses revealed that income inequality would increase by 6 percentage points for all households if environmental income was excluded. The results generally suggest that environmental income is important for both the poor and the well-off, and wealth accumulation might be tied to resource use. There is a case for promoting sound environmental management, and sustainable and fair resource use in the Kalahari drylands in order to help pull more households out of poverty. Our findings also point to issues of heterogeneity in resource access even among indigenous communities previously thought to be homogenous. These should be key considerations for conservation interventions.

  • Description: The current study investigated the determinants of Internet services’ adoption and use among high school learners in the East London Education District, in the Eastern Cape. Underpinned by the Unified Theory of Acceptance and Use of Technology, the research questions included: (1) What is the effect of performance expectancy on the learner’s intention to adopt and use Internet services? (2) What degree of variation exists for effort expectancy on the learner’s intention to adopt and use Internet services? (3) How much of the determinants explain the usage of Internet services? (4) Which is (are) the best predictor(s) of Internet service usage given a set of determinants? (5) What is the effect of confounding variables (if any) on Internet services’ adoption and usage? (6) Which model can be designed based on the best predictor(s) of Internet services’ adoption and usage for secondary school learners? A quantitative approach based on the positivist paradigm was used to quantify the relationships among various factors that contribute to Internet services’ adoption and use. The research design used was a survey. Data were collected through structured questionnaires. Out of 286 questionnaires issued, the response rate was 40.6%. The study sample size was 116 high school learners using simple random sampling. The data was analysed using the multiple regression analysis technique, and Pearson correlations. Out of the four determinants from the UTAUT, performance expectancy was the strongest predictor of intention to adopt Internet services. Large positive correlations ranging from r = 0.638 up to r = 0.989 were found among performance expectancy and effort expectancy variables towards the intention to use Internet services, significant at p < 0.05. To enhance the efficiency of the UTAUT model, this study has designed the Adoption and Application of Technology for Learning (AATL) model, which added the price of Internet, persistent use of Internet, and perceptions about Internet use.

  • Description: In regard to employment, people with disabilities are discriminated. Unfavourable employer attitudes result in discrimination toward people with disabilities. Entering and progressing in employment create a sense of independency, responsibility and build the self-esteem of people with disabilities. This study sought to determine the influence of individualism-collectivism and demographic factors (age, gender, and level of education) of managers’ attitudes toward employing people with disabilities in small and medium enterprises in Nkonkobe Municipality in the Eastern Cape Province. The social and medical model of disability provided a framework for understanding the literature on attitudes toward people with disabilities. Data was collected from 110 respondents in small and medium enterprises using two scales (Individualism-collectivism Scale and Employer Attitudes toward People with Disabilities Scale). Independent t-tests were used to test each of the hypotheses in the study and ANOVA was used for comparisons among variables. No significant differences found in attitudes on individualistic and collectivistic oriented managers toward employing people with disabilities. In addition, no significant differences in attitudes of managers over age, gender and level of education toward employing people with disabilities in small and medium enterprises. People with disabilities can be a benefit to the organisations since their skills and talents can help the organisations to remain stable in the competitive global environment. , Thesis (MCom (IPS)) -- Faculty of Management and Commerce, 2014

  • Description: Informal caregiving denotes care that is provided by a family member or friend rather than by a professional who is reimbursed for services. Assuming a caregiving role can be stressful and burdensome. The effects of caregiving on the caregiver's health are moderated by individual differences in resources and vulnerabilities, such as socioeconomic status, prior health status, and level of social support. This work describes the determinant of psycho-social well-being of informal caregivers of physically challenged children in southwest of Nigeria. This study is guided theoretically by Ryff”s psychosocial well-being theory, The study adopted expo facto research design. Multistage samplings involving the use of random and purposive techniques were used to select 812 respondents who are informal caregivers. Social support questionnaire, Social support satisfaction level, Ryff’s psychological well-being scale were used. Findings indicated that social support predicted psycho-social well-being of informal caregivers of physically challenged children. Social support and satisfaction level combine together have impact on psycho-social well-being of informal caregivers of physically challenged children. More also, socio-economic factors such as occupation, educational level and income also predict psycho-social well-being of informal caregivers. Finally, marital status and gender also contribute to well-being of caregivers. It was therefore, recommended that social inclusion should be pursued with de-institutionalization of children with disability. Parents of children with disability should be encouraged to form support group and as well as encouraging fathers of children with disability to take an active part in ensuring their children with disability well-being. More also, there is need to empower informal caregivers through training and education. More importantly governments at the three levels ( Federal, State and local) should assist caregivers at ensuring their own and that of their children with disability well-being through improvement on various existing social welfare services in the country.

  • Description: Despite the continuing perceived economic centrality of agriculture in Intsika Yethu local municipality, rural households engage and pursue diverse non-farm livelihood activities to cope with diverse challenges and risks such as drought. This study assessed the importance of existing livelihood strategies adopted by the different rural households in Intsika Yethu; the link between households’ ownership and access to different ‘assets’; factors determining households’ ability to adopt certain livelihood strategies in the area. A survey of 120 households in six administrative areas and informal discussions with key informants were used to collect demographic data, data on socio-economic activities and factors determining the choice of livelihood strategies of the households in Intsika Yethu. The research findings indicated that only about 10% of the interviewed households relied solely on on-farm livelihood strategy only. Credit, remittances, market distance, affiliating to cooperatives, education and household size have a potential of influencing households to shift from on-farm livelihood strategy to other livelihood strategies. The government may need to promote programs and awareness on how households can diversify their livelihood strategies as a way of coping with economic constraints in the area.

  • Identifier: vital:11496
  • Description: The yield curve has been the subject of many studies for some time, mainly in predicting recessions, economic growth and inflation. However, scant work is available on what drives the yield spread. Given this, the paper examines the determinants of the yield curve in South Africa by using time series econometric analysis over the period 2000-2012. Some key variables considered include inflation, economic growth, budget deficit, and monetary policy. To separate the long and short run effects, VECM was employed after ensuring stationarity of the series. The study found that a long run relationship exist between the yield spread, inflation, GDP, budget deficit, Repo rate, Real effective exchange rate and a money supply (M1). The Results of this thesis have implications for policy and academic work.

  • Description: The increase in number of banks entering the South African banking sector has caused the big four banks to lose their market share to the new entrants. As a result, the new entrants in this sector have also had negative effects on the existing banks’ sales growth and net profits. Business banking, in particular, has been one of the departments which has become competitive as it is considered to generate the most revenue from all the different bank departments. Business clients have been targeted as their fees are high compared to normal individual clients and also, their investment sizes are big compared to individuals, hence the increased interest in this section. This then prompts the question, what are the factors influencing sales growth in business banking? This question then brings one to the following sub-problems: Is the pricing offered by the various banks to their business bank customers competitive enough to retain them?; How competent and knowledgeable is the staff dealing with business bank customers in ensuring good relationships with business banking clients?; is the technology used by the banks advanced enough to address the banking requirements of business banking customers? Are business banking customers loyal to their respective banks to ensure repetitive sales? In dealing with the above, the author undertook a research study to determine whether factors such as competitive pricing, competent staff, advanced technology and customer loyalty influence sales growth in business banking in Buffalo City Municipality “BCM”. The sample of 90 business banking customers who were given questionnaires to test the above were from a population of business banking customers in BCM. The author underwent a theoretical and an empirical investigation using the survey method through questionnaires. These questionnaires were distributed to the various financing institutions dealing with business banking clients. The findings of the empirical study suggest that through the use of the hypothesis test, it was concluded that of the four factors, advanced technology and customer loyalty influence sales growth in business banking in BCM. While pricing and competent staff do not influence sales revenue growth.

  • Description: South Africa is a society of diverse cultures, and the workplace is one of the few places that serve as a melting pot for these varied cultures. If managed well, cultural diversity has numerous benefits that can help an organisation gain a competitive advantage. However, failure to manage it can pose challenges that can have serious consequences for an organisation. The purpose of this study was to analyse the leadership of cultural diversity at Volkswagen South Africa (VWSA) and identify leadership guidelines to both enhance team performance and reduce the challenges faced by the organisation as a result of this cultural diversity. For the purpose of this study, a culturally diverse team was defined as a team of diverse individuals from different cultures or societies working together to achieve organisational success. The research was conducted by the use of questionnaire using a sample of 200 employees of the VWSA Paint Shop. The sample represents 42 percent of the total population of the Paint Shop. The study discusses the relationship of four leadership styles (Classical Leadership, Transactional Leadership, Transformational Leadership, and Visionary Leadership) with Cultural Diversity. Whilst strong cases were made for Transformational and Transactional Leadership style being the most suitable styles for leading culturally diverse teams, the researcher concluded that no single leadership style would be ideal for effectively leading culturally diverse teams at VWSA. The appropriate leadership style will instead be a hybrid of all leadership styles, thus being a leadership approach that works as a sort of “best practices” of various leadership styles.

  • Description: This chapter argues for a critical perspective on the use of lo-cal knowledge and practices in teaching and learning, present-ing some pedagogical thinking tools for reviewing intergenera-tional teaching and learning processes. The chapter highlights five relational elements in teaching and learning processes, including the relationship between individual and community, social and historic contexts, school-based actions and local practices, local and regional/national/global concerns, and fi-nally between local knowledge and abstract school knowledge. These relational elements of learning illustrate how it is possi-ble to mitigate against conservative, over-simplistic or idealistic responses to environmental concerns. This argument is illus-trated through reference to a lesson designed and implement-ed by a school teacher participating in a Rhodes University ac-credited teacher professional development course–the Schools and Sustainability course. This teacher depended substantially on intergenerational communication for her les-son, which supported Grade 1 pupils to research the use of wild vegetables historically in their community and plant these vegetables in their school garden with the support of knowledgeable community members.

  • Description: The increasing number of proposed wind farm developments in South Africa provides an immediate reason to assess bat activity and diversity, with the expectation of developing measures to mitigate for negative impacts. The overall aim of this thesis was contribute to an understanding of the drivers of bat activity, relevant to wind turbines, and to determine what factors (exogenous – environmental, or endogenous – intrinsic physiological processes) contributed to observed bat activity patterns, at the Metrowind Van Stadens Wind Farm in the Eastern Cape of South Africa. A combination of active (mist netting) and passive (acoustic) bat monitoring techniques were used to determine free-ranging bat activity patterns (Chapter 3). A total of 889 bat passes were recorded over 323 detector nights from the beginning of May 2012 to the end of December 2012. The Cape serotine bat (82 per cent) and the Egyptian free-tailed bat (97 per cent) made up the majority of all bat passes recorded on site. Large variations in bat activity per month and per hour were apparent, with bat activity peaking in May 2012 and during the first few hours after sunset (18:00-23:00). Patterns in nightly, free-ranging bat activity at the site were modelled against various environmental conditions. Month, temperature, wind speed and an interaction between month and rainfall were the most significant predictors of bat activity, explaining 80 per cent of the variation observed on free-ranging bat activity patterns. A total of eight Cape serotine bats (Table 4.1.) were caught in mist nets on site and changes in the resting metabolic rate (RMR) of torpid (n = 6), and normothermic (n = 2) bats, over a 24 hr period, were measured and used to predict free-ranging Cape serotine bat activity (Chapter 4). Cape serotine bats showed a high proclivity for torpor in the laboratory and peaks in RMR were observed at 18:00 (0.89 ± 0.95 VO2 mℓ.g-1.hr-1) and again from 20:00-21:00 (0.89 ± 0.91 VO2 mℓ.g-1.hr-1). Peaks in RMR of torpid individuals coincided with peaks in the average hourly free-ranging activity of the Cape serotine bat, and RMR explained 33 per cent of the variation and was a good predictor of free-ranging bat activity (R2 = 0.2914). This study showed that both exogenous (Chapter 3) and endogenous (Chapter 4) factors drive bat activity in the wild. Although this dissertation was not intended for wind turbine management, the information presented on the biology and activity of bats is important for managing interactions between bats and wind turbines. By determining what factors influence bat activity, we are able to predict when bats will be most active and thus can develop mitigation measures to reduce the potential impacts that wind turbines will have on the bat community. In order to conserve bats and reduce potential bat fatalities from occurring at the site, mitigation measures should be concentrated to those times when bats are most active (May and during the first few hours after sunset – 18:00 to 22:00).
