- Description: This study set out to evaluate the development potential of extractive sector corporate social investments (CSI) in Cameroon. It does this by evaluating the extent to which extractive companies effectively integrate CSI in their business operations and how this can be improved upon for more effective development outcomes in the country. The study premises that CSI can contribute to development but its activities will not always amount to just, balanced and sustainable development outcomes. To understand the extent to which it does, this study develops and applies a framework for determining the applicability and effectiveness of extractive sector CSI practices. The research followed an interpretivist philosophical orientation. A case study research strategy with the elements of a survey research was used. It also implemented a mixed research methods approach and relied on both primary and secondary data sources. The CSI evaluation process used documentary survey techniques and content analysis of corporate social responsibility-related documentation provided by extractive companies and other sector stakeholders. This was triangulated with an expert survey as well as a survey of major development organisations to understand the opinion of the external environment that should shape CSI practices. Results were analysed, discussed and synthesised using the front-end, mid-phase and back-end criteria for evaluating CSI integration. Findings show significant level of adherence to the discretionary idea of CSI among extractive firms working in Cameroon. This is due partly to growing social responsibility awareness among extractive firms around the world and the consequence of inaction. The greater majority of companies however, do not show strong proof of well thought out CSI implementation strategies. The feeling among experts is that extractive sector CSI in Cameroon is failing. It is predominantly self-regulated by extractive companies which raise questions regarding objective and credible CSI practices. The study concludes that CSI has been implemented in ad-hoc, haphazard and un-systematic ways. It has a viable potential to contribute to development but still suffers from a very weak CSI enabling environment as well as the challenges of sustainable development. Extractive sector CSI therefore, still needs to be significantly reworked to enhance its potential in contributing to just, balanced and sustainable development in Cameroon. It is recommended that an enabling environment be put in place through CSI promotional activities in the country.

- Description: The chemical analysis of feed samples can be time consuming and expensive. The use of near infrared reflectance (NIR) spectroscopy was evaluated in a range of studies as a rapid technique to predict the chemical constituents in feedstuffs and compound ostrich feeds. The prediction of accurate results by NIR spectroscopy relies heavily upon obtaining a calibration set which represents the variation in the main population, accurate laboratory analyses and the application of the best mathematical procedures. This research project was designed to meet five objectives: The first objective was to determine the feasibility of using near infrared reflectance (NIR) spectroscopy to predict dry matter, ash, crude protein, crude fibre, oil content, and fatty acids such as palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1) and linoleic acid (C18:2) in sunflower seed meal. The second objective was to develop calibration models to predict the dry matter, crude protein and oil content in milled canola seed, compared to whole canola seeds. The third objective was to investigate the feasibility of using NIR spectroscopy to predict the dry matter, ash, crude protein, crude fibre and oil content in milled lupin seeds, compared to whole lupin seeds. The fourth objective was to describe the development of near infrared reflectance (NIR) spectroscopy calibration equations for the prediction of chemical composition and amino acid content from different populations of alfalfa hay (Medicago sativa L.). The last objective was to determine the potential of NIR spectroscopy to predict the dry matter, ash, crude protein, crude fibre, ether extract, acid detergent fibre (ADF), neutral detergent fibre (NDF), calcium, phosphorus, in vitro organic matter digestibility (IVOMD) and amino acids such as lysine, methionine, threonine and arginine in compound ostrich feed samples. The results of this study indicate that NIR spectroscopy calibrations in sunflower seed meal are only applicable in sunflower breeding programmes for a fast screening as it was not suitable for prediction purposes. Screening of sunflower seeds by NIR spectroscopy represents a rapid, simple and cost effective alternative that is a great utility for users who need to analyse a large number of samples. Calibrations developed for crude protein and oil content in milled canola seeds proved to be better than calibrations for whole canola seeds. Although the results indicated that calibrations were better for milled canola seeds, it indicated values that were typical of equations suitable for screening purposes to select samples for more detailed chemical analysis. According to calibration statistics obtained for crude protein, crude fibre and oil content in whole lupin seeds, there is no need to grind the seeds to scan the meal as similarly accurate results were obtained by analysing whole seeds. Screening of whole lupin seeds by NIR spectroscopy represents a rapid, simple and cost effective alternative that may be of great utility for users who need to analyse a large number of samples with no sample preparation. The calibration and validation statistics obtained in the study to test the potential of NIR spectroscopy to predict the chemical composition and amino acid contents in alfalfa hay, showed the accuracy was too low for routine analysis, although NIR spectroscopy could be used as a screening tool. Further research needs to be done to improve the accuracy of the NIR spectroscopy analysis, including more samples from different cultivars and years. In the study to examine the possibility of using NIR spectroscopy to predict the chemical composition of compound ostrich feeds, the results indicated that NIR spectroscopy is a suitable tool for a rapid and reliable prediction of the crude protein, crude fibre, ether extract, IVOMD, ADF and NDF in compound ostrich feeds. Calibrations can be improved for amino acids if a larger sample pool is used to develop the calibrations. These studies indicated that NIR spectroscopy can be a rapid and successful tool for the prediction of the nutritive value up to certain amino acid contents of feedstuffs and compound ostrich feeds.

- Description: The fresh hake processing lines at Seavuna fishing company in Mossel Bay are not consistently achieving their volume output standards and this is resulting in higher processing costs and loss of processing opportunities. The company’s senior management are concerned about this trend and require a complete review of the effectiveness of the resources deployed on the lines. This with the view of establishing the causes of poor process volume output. In order to resolve the process inefficiency challenges mentioned, this study used both empirical and time studies to investigate the effectiveness of the company’s resources directly deployed in the processing unit. The study focused on investigating the human factor, machinery and equipment, the environment and the current efficiency standards. Relevant literature in the field of process efficiency improvement was consulted to assist in identifying factors that are known to cause process inefficiencies, and also to establish which improvement techniques would be relevant in correcting the situation. From the Literature reviewed, it was evident that a ‘one size fits all’ solution to resolving inefficiencies is almost non-existent and that a solution that is relevant to the problem is more effective. In addition, a benchmarking exercise was also done to establish how Seavuna’s current volume output standards fair against its major rivals. Once data from both studies were collected, the results were analysed using the some of the basic quality tools. Thereafter, lean manufacturing principles were used to attempt to resolve the current efficiency challenges. The study recommended that the company construct a business strategy and a corresponding organisational culture to direct its continuous improvement interventions. The use of strategic quality planning would go a long way in assisting the company to execute some of the interventions recommended.

- Description: This study examined experiences of teachers in ex-Model C secondary schools in Port Elizabeth with specific reference to the strategies adopted, challenges and rewards of teaching in diverse classrooms. It is located in the realm of diversity pedagogy and multi-cultural education and contextualized against the socio-political and colourful historical climate of education in South Africa. This study was conducted by using the qualitative research approach against the backdrop of the phenomenological design according to the interpretivist paradigm. Data were elicited through in-depth semi-structured interviews with 16 teachers from 4 ex-Model C English medium secondary schools (formerly White schools) who had experiences of teaching both pre-1994, when schools were mono-ethnic, and post-1994 when the schools were multi-ethnic. The interviews were transcribed and the rich thick data were analysed and categorized into themes and sub-themes by adopting a constant comparative method. The findings of the study indicate that teachers failed to embrace diversity to its fullest, although they did not mind teaching diverse learners. Furthermore, it is evident that they have not made concerted efforts to implement culturally responsive teaching strategies to cater for diversity in their classes as the approaches tend to be cosmetic and superficial. The findings indicate that teachers are stuck in the quagmire of business as usual-, colour-blind-, assimilationist, contributionist approaches that militate against culturally responsive pedagogy. It is recommended that teachers be empowered with skills in diversity education by various stakeholders such as School Governing Bodies, the Department of Basic Education and teacher unions so that they are better equipped to implement strategies in their classes that cater to the needs of a diverse learner population.

- Description: Commercial trading in various formats has characterised relations between humans for centuries. However, in a world driven by higher levels of consumption, and where citizens demand higher returns for their hard-earned taxes, governments are becoming more active in ensuring favourable conditions for their own enterprises, either operating or seeking to operate, in foreign markets, as well as local enterprises that seek to extract value from foreign markets. The past failure of the markets to self-regulate, with the recent events of the 2008/09 market crash, gave fresh impetus for governments to play a more active role in ensuring favourable outcomes for their local economies. To be effective, requires the deployments of capable officials to fulfil this mandate. However, given that governments have traditionally not operated in the sphere of what is termed as ‘commercial diplomacy’, it is evident that a concerted effort needs to be made to have a skilled and capable workforce which can function in both the commercial and diplomatic market spaces across the world. Against the background sketched above, the South African government, with the dti spearheading the initiative, has been running capacity building programmes to train officials as designate FERs, to function as commercial diplomats in targeted foreign markets. This contrasts with its sister-department, DIRCO, which has established 126 foreign missions focusing on political diplomacy. Anecdotal evidence, and previous capacity building reports, have highlighted the need for a framework to regulate and inform the development of officials. Due to the framework’s broader focus, and the acknowledgement of the rich experiences of the officials being trained in the programme, it has been termed as capacity development. An initial review of the topic, revealed that there had been limited research into a framework that regulates the capacity development of foreign economic representatives (FERs), the term used for commercial diplomats of the South African government. Thus, the purpose of this study was to explore a capacity development framework (CDF) for South African FERs. This exploratory capacity development framework will then be tested, to inform the capacity development programme used for the training of designated FERs. To achieve this goal, a literature review of academic sources of information regarding the concepts of commercial diplomacy, capacity development and conceptual frameworks, was conducted. This led to the development of a qualitative questionnaire which was then distributed to all currently posted (27) and returned FERs (33), with 18 completed questionnaires returned. The questionnaire contained both closed and open-ended statements that delved deeper into the experiences and opinions held by the respondents. Using the dti as a case study, the content analysis method, which uses open coding, was applied to identify the theme and codes emanating from the data. This was assessed against the research questions (RQs) constructed in the research proposal, and was found to be in line with the sentiments flowing from the research data. The theme, indicated as capacity development and its concomitant codes (Process, Content, Technology and Management Support), thus formed the basis and skeleton of the exploratory capacity development framework. The codes were further analysed and sub-codes identified, which were incorporated into the exploratory capacity development framework. The analysis further revealed that, while the dti is committed to ensuring the designate FERs are adequately capacitated before being posted, much more could be done to improve the efficacy of the training provided. To this end, a number of gaps were identified from the data and these will need to be addressed to ensure that an effective capacity development programme is developed.

Exploring feeding ecology and population growth rate responses of ungulates in Southern African arid biomes

- Description: Limited resources, extreme temperatures and predators are some of the stresses that are faced by ungulates in arid biomes. Understanding how these stressors influence ungulate feeding ecology and population growth rates is important for managers, as these could influence the persistence of ungulates in protected areas. An understanding of these stressors is especially relevant given the significant population declines in ungulate species globally. The Nama Karoo biome and the arid Savanna, an arid form of the Savanna biome, are both arid, but have distinct rainfall seasonality and vegetation structure and represent unique characteristics that need to be properly considered in their own regard. The literature on African ungulate feeding ecology covers a range of species and biomes from southern and east Africa, however, very little is known about ungulate dietary preferences in the Nama Karoo. Unexplained population declines in springbok (Antidorcas marsupialis) and red hartebeest (Alcelaphus buselaphus caama) have occurred at local scales across the Nama Karoo and the arid Savanna, most notably springbok population declines at the Karoo National Park (Karoo NP). This study sought to improve the understanding of ungulate feeding ecology and population growth rate responses in two arid biomes of South Africa. To achieve this, ungulate dietary composition was characterised, in terms of the proportional seasonal contribution of C4 and C3 plant forms, of a range of ungulates in the Nama Karoo, at the Karoo NP and the arid Savanna, at the Tswalu Kalahari Reserve (Tswalu KR), using stable carbon isotope analysis. Fresh faecal samples of ungulate species were collected from both the biomes during the dry, early wet and late wet seasons. Species were categorised per biome into feeding guilds and the effects of season, biome and the interaction thereof on the diets of the ungulate species explored. Furthermore, the findings were interpreted against what is known about diets of the respective species elsewhere in southern and east Africa. Secondly, trends in ungulate population growth rates were assessed within the Karoo NP and the Tswalu KR over the past 12 and14 years respectively. Furthermore, the variables influencing ungulate population growth rates (and generality of trends), with emphasis on ungulate biomass and rainfall, were explored at biome and species level. Population size data were obtained from annual aerial censuses for the period 2002-2015 and used to calculate annual growth rates and biomass for each ungulate species. The contribution of C4 forage to the diets of ungulate species in the arid Savanna was generally higher than in the Nama Karoo,in line with greater relative abundance of C4 grasses in the former. During winter (dry season) C3 intake was higher in the Nama Karoo than in the arid Savanna, reflecting C3 plant growth (C3 grasses and shrubs) and rainfall during winter in the Nama Karoo. Mean population growth rates during the study period were negative in some of the threatened species considered, i.e. mountain reedbuck (Redunca fulvorufula fulvorufula), tsessebe (Damaliscus lunatus lunatus) and Hartmann’s mountain zebra (Equus zebra hartmannae). No evidence for negative density dependent regulation (~intra-/interspecific competition) of ungulate population growth rates was found, whereas bottom up (~rainfall) and positive density dependent (~biomass of the species under investigation) regulatory mechanisms were most influential. The rainfall and biomass variables influenced the population growth rates of smaller ungulate species more than those of larger bodied ungulate species. Knowledge of ungulate diets will enable managers of protected areas to better understand how climate change, and resultant changes in relative abundances of plant growth forms, will influence specific ungulate species. The finding that increased population biomass positively influenced certain ungulate species’ growth rates has potential implications for management intervention as ungulate biomass is a variable that can be manipulated in protected areas. The reinforcement of existing mountain reedbuck, springbok and red hartebeest populations, specifically, at the Karoo NP and the Tswalu KR may counter their current negative growth rates in these two protected areas. Finally, the influence of protected area size and fencing, on ungulate vulnerability to predators (~top down) and forage quality (~bottom up) mechanisms in arid biomes needs to be further explored.

Fresh faecal samples of ungulate species were collected from both the biomes during the dry, early wet and late wet seasons. Species were categorised per biome into feeding guilds and the effects of season, biome and the interaction thereof on the diets of the ungulate species explored. Furthermore, the findings were interpreted against what is known about diets of the respective species elsewhere in southern and east Africa. Secondly, trends in ungulate population growth rates were assessed within the Karoo NP and the Tswalu KR over the past 12 and14 years respectively. Furthermore, the variables influencing ungulate population growth rates (and generality of trends), with emphasis on ungulate biomass and rainfall, were explored at biome and species level. Population size data were obtained from annual aerial censuses for the period 2002-2015 and used to calculate annual growth rates and biomass for each ungulate species. The contribution of C4 forage to the diets of ungulate species in the arid Savanna was generally higher than in the Nama Karoo,in line with greater relative abundance of C4 grasses in the former. During winter (dry season) C3 intake was higher in the Nama Karoo than in the arid Savanna, reflecting C3 plant growth (C3 grasses and shrubs) and rainfall during winter in the Nama Karoo. Mean population growth rates during the study period were negative in some of the threatened species considered, i.e. mountain reedbuck (Redunca fulvorufula fulvorufula), tsessebe (Damaliscus lunatus lunatus) and Hartmann’s mountain zebra (Equus zebra hartmannae). No evidence for negative density dependent regulation (~intra-/interspecific competition) of ungulate population growth rates was found, whereas bottom up (~rainfall) and positive density dependent (~biomass of the species under investigation) regulatory mechanisms were most influential. The rainfall and biomass variables influenced the population growth rates of smaller ungulate species more than those of larger bodied ungulate species. Knowledge of ungulate diets will enable managers of protected areas to better understand how climate change, and resultant changes in relative abundances of plant growth forms, will influence specific ungulate species. The finding that increased population biomass positively influenced certain ungulate species’ growth rates has potential implications for management intervention as ungulate biomass is a variable that can be manipulated in protected areas. The reinforcement of existing mountain reedbuck, springbok and red hartebeest populations, specifically, at the Karoo NP and the Tswalu KR may counter their current negative growth rates in these two protected areas. Finally, the influence of protected area size and fencing, on ungulate vulnerability to predators (~top down) and forage quality (~bottom up) mechanisms in arid biomes needs to be further explored.

- Description: Autism Spectrum Disorder is not a modern phenomenon. Researchers have been studying children with “autism-like” characteristics for over one hundred years and only now it has become recognised, as it is a growing phenomenon. Autism is a vast and complex disorder with a range in which a child’s “autism-like” characteristics fall. Although, the primary distress of autism falls mainly on the child’s shoulders, primary caregivers such as mothers, are faced with many challenges due to the core behavioural characteristics. These challenging behaviours often leave mothers blaming themselves and defending their parenting skills. There are extensive publications regarding parenting that have been published through the years on children who do not have any diagnosed conditions, but limited research and publications exist in the area of parenting children on the autistic spectrum in general and in the South African context. The aim of this study was to explore and describe the maternal parenting styles and methods of discipline in relation to autistic children’s challenging behaviour. The present study incorporated Diana Baumrind’s Parenting Style Model as a framework to better understand the maternal parenting styles and methods of discipline. This study was explorative and descriptive in nature and a biographical questionnaire and a semi-structured interview schedule was utilised to gather data until saturation had been reached. A non-probability purposive sampling technique was employed to obtain participants and thematic analysis was used to analyse data and to extract themes. This study seeks to contribute to psychology's existing body of knowledge by conducting research on parenting styles of learners on the autistic spectrum in South Africa. By conducting this study the researcher hopes to be able to assist parents and helping Exploring Maternal Parenting Styles and Methods of Discipline in Relation to Autistic Children’s Challenging Behaviour in the Home Environment professionals with an understanding of the parenting styles and the methods that are being used to discipline the autistic child’s behaviour in the home environment.

- Description: A mere glance at a family photograph of the Victorian era leaves little doubt of the position of the figure exuding impervious, authoritarian detachment. Austere, rigid and solemn, it is not hard to guess who cast the shadow over the picture. Arrestingly imposing in his role as backbone of the family, this is the nineteenth century legacy image of the father. However, the last century has seen fatherhood redefine itself and the more liberal, lenient and openly loving figure replaced the strict patriarchal model. In contemporary times, fathers are regularly seen comfortably behind a stroller, outdoors with children on their shoulders, at home tousling with their children, and considerably more involved in school and social events. Unashamedly, fathers have moved toward both acknowledging and displaying a softer paternal image. By definition fatherhood is a decidedly individual concept and a unique experience, involving much more than being the male parent in a family, the family protector, or the provider of paycheques. Although the past decade has seen a surge of research and interest in fatherhood with an increased recognition that the involvement of fathers contribute to the well-being, cognitive growth and social competence of their children, there remains a deficit in research on the experiences, perceptions and involvement of fathers of children diagnosed with Down syndrome. And whilst most of this knowledge base is extrapolated from studies about the mother’s experience, true understanding requires that fathers are studied directly. Mothers and fathers respond differently to the pressure associated with raising a child with Down syndrome and literature supports the common view that men are less likely and easy to engage in therapy than women, are less likely to attend therapy, or seek help for physical or psychological problems. For fathers of any differently abled child, the distance between the idealized fathering experience and the actual one may be enormous. Based upon the patriarchy model of the family, in many conventional homes, the wife and mother is like a thermometer, sensing and reflecting the home’s temperature, whilst the father and husband is like the home’s thermostat, which determines and regulates the temperature. The equilibrium of the father plays an important role in his ‘thermostat settings’ to set the right temperature in the marriage and his family. Having a differently abled child is almost never expected and often necessitates a change in plans as the family members adjust their views of their own future, their future with their child, as well as how they will henceforth operate as a family.Some fathers may experience uncertainty about their parenting role of a child diagnosed with Down syndrome, often resulting in peculiar behaviours of the father. This may include engrossing themselves into their work, hobbies, sport, and so forth, almost abdicating their duty as father; believing that the mother knows best (sometimes using their own lack of knowledge as a cop-out); or, they simply withdraw because the mother takes such complete control of every aspect of the child that the father feels inadequate, superfluous, and peripheral as parent. Each parent grieves the ‘loss’ of the child they expected in their own individual way. However, such a highly emotive situation may be compounded by the following aspects: the undeniable pressure of caring for the differently abled child; the additional financial burden; a waning social life; and, the incapacity to cope emotionally whilst invariably displaying the contrary purely to create the illusion that they are indeed coping. Fathers need to develop strategies and skills to cope with the very real and practical needs of parenting their child with Down syndrome, to furthermore minimize relationship conflict and misunderstanding, and to support their child’s optimal development. How these specific issues are embraced and managed may dramatically influence the peace and harmony of family life as well as the marital relationship. This study explores the perspectives of fathers of a child with Down syndrome to ultimately support this unique journey as they navigate their way through “Down”town Holland, as illustrated in the analogy to follow.

- Description: The increased rate of teenagers suffering from reproductive healthcare -related conditions is a global phenomenon. An estimated 16 million teenage girls aged between 15 and 19 years give birth every year with 95% of these births occurring in the developing countries. In South Africa one notes from recorded statistics that 20000 school going teenagers fell pregnant in South Africa during 2014. These statistics left many questions to be answered in terms of what information school going teenage girls do receive at school. Formally the current school curriculum in South Africa includes a subject around life skills orientation which is known as Life Orientation Programme and in which learners are introduced to reproductive healthcare from grade 7; but a persistent increase in the rate of pregnancies and sexually-transmitted infections amongst school going teenage girls is observed. The aim of the study was to explore and describe the knowledge of school going teenage girls regarding reproductive healthcare and services in the Eastern Cape Province. The objectives of this study were:-to determine and explore the knowledge of school going teenage girls regarding reproductive healthcare in the Eastern Cape Province; -to determine the nature of information given to school going teenage girls regarding reproductive healthcare through the school Life-Orientation programme; and,-based on the results of the entire study, develop guidelines that could assist the stakeholders in health and education professions in enhancing of knowledge regarding reproductive healthcare of school going teenage girls and improving their access to related services. A quantitative design with a descriptive, exploratory and contextual approach was used. A survey was conducted and the data -collection tool was a self-administered, structured questionnaire developed by the researcher with the assistance of the supervisor and the statistician. Validity and reliability were assured before data collection commenced. A convenience, non-probability sampling method was used to collect data from schoolgoing teenage girls that gave permission to participate and met the inclusion criteria of:- schools having school going teenage girls between the ages of 12 and 19 years in the Eastern Cape Province, - being within the Nelson Mandela Bay Municipality areaand the Sarah Baartman district and -the schoolgoing teenage girls being in grades 10 to 12. Data was collected in September 2016 from a total of 314 teenagers who participated and returned the completed questionnaires. The data was captured by the researcher and analysed using a Microsoft excel programme created by the statistician for data - analysis purposes. STATISTICA Version 12 computer software application was used. The study results revealed that learners received some reproductive healthcare related education in Life-orientationprogramme lessons; but the information was seen as insufficient. Parents were telling them about their body development; but were not discussing reproductive healthcare issues with them. Participants did not know how to use the different methods of contraceptives correctly though they knew about the methods. Participants did not know about other signs of complications of reproductive healthcare as they did not know how to identify sexually-transmitted infections, breast and vaginal infections and related problems. Based on the above study results guidelines wasdeveloped as the necessary tool to facilitate the enhancement of schoolgoing girls’ knowledge regarding reproductive healthcare in the Eastern Cape Province. The study adopted the Belmont Report principles, namely, respect for persons, beneficence and justice, to enhance ethical considerations.

- Description: It is well documented that tertiary institutions in South Africa are reporting high failure rates in accounting courses; several calls have been made to address this in recent years. Various reasons are given for this high failure rate, such as an increase in student numbers and diversity, a mismatch between programmes and students, unequal schooling and inequity of access to tertiary institutions, an increase in the number of underprepared students for tertiary education, and difficulties with language. As a result, there is a growing interest in the factors predicting academic performance, and several studies on predicting academic performance have been undertaken both internationally and in South Africa. Scholars have specifically identified several factors that influence failure in accounting in the first year of tertiary education and in first year accounting in particular. However, the focus of the current study was on several biographical and educational factors only, factors that have commonly been found to influence student performance in their first year, namely: Gender, Age, Ethnicity, Home language, School category, School language, Nationality, Degree programme, Repeating (the accounting module), Admission Point Score (APS), Matric LAMN (combined score for Matric language, accounting, mathematics and numeracy), whether the student studied Accounting in Matric, and Matric year. The primary objective of this study was to develop a predictive model based on biographical and educational secondary data for identifying students at risk in first year accounting at Nelson Mandela Metropolitan University (NMMU). A quantitative research design was adopted and a non-experimental, descriptive study of a cross-sectional and deductive nature was undertaken. The non-probability sampling technique of criterion sampling was used and the sample consisted of all students enrolled for the R101, RNC101, R102, RG102 and RNC102 first year accounting modules in the Department of Accounting Sciences at NMMU. Historical data, both biographical and educational, was collected on which to undertake the data analysis. The data was analysed by means of descriptive statistics and logistic regression analyses. A separate logistic regression analysis was undertaken for each module group because of the diversity of curriculum content and participants of each module group. The findings show that as a whole, the levels of model accuracy in predicting the at-risk and not-at-risk categories were high. The R101 model showed the highest overall prediction success rate with 80.10 per cent of students being accurately classified into either the at-risk or not-at-risk category. The RG102 model showed the lowest overall prediction success rate of 73.91 per cent. The predictor variables of Matric accounting and Home language were identified as the most significant factors in predicting at-risk first year accounting students because they predicted at-risk students in three of the five logistic regression models, while School language, APS, Matric LAMN, Gender and Age were significant in predicting at-risk students in two of the five logistic regression models. The findings of the current study are interesting in highlighting that Matric accounting is not a predictor for students who intend majoring in accounting. They also highlight that for students who intend majoring in accounting in order to become CAs, English language proficiency is an important predictor for at-risk students. For students who intend majoring in accounting and becoming a CA, the findings show that African-home-language students are the most likely to be at risk in the first semester of first year accounting, while Afrikaans-home-language students are the least likely to be at risk in first year accounting. Several observations and recommendations are made and those that are of particular importance to the R101 module relate to Matric accounting, language, APS and Matric LAMN, as well as Gender and Age. For the R102 module, it is those relating to language and Matric LAMN, and for the RG102 module, it is those relating to APS. For the RNC101 module, the observations and recommendations that are of particular importance are those relating to Matric accounting and language as well as Gender and Age, while for the RNC102 module, it is those relating to Matric accounting. The ability to identify at-risk students in first year accounting is of great value to universities across South Africa at institutional, faculty and programme level. The predictive model developed assists in identifying at-risk students timeously, and early identification allows for targeted interventions and support, which could assist these students in overcoming their challenges and ultimately improving pass rates.

- Description: The HIV and AIDS prevalence in Kenya is still high and remains a major health concern despite the Kenyan government’s initiatives to create awareness about the epidemic through inclusion of the HIV and AIDS programme in schools. This is because the provision of sexuality, HIV and AIDS education in schools is not effective. Teachers face various challenges in the effective delivery of the subject due to their discomfort related to these sensitive topics. Therefore, learners are left inadequately supported by the teachers. With an immense variety of conflicting information about sexuality availed to young people through the social media and also through their peers, young people are left at risk of exploring their sexualities with inadequate and wrong information, thus exposing them to HIV infections. Since schools have been identified as ideal sites for the effective delivery of sexuality, HIV and AIDS education, teachers are expected to teach the learners using a variety of pedagogical strategies in order to achieve efficacy in the delivery of this subject, hence the need to explore teaching styles that could provide a safe space for the effective delivery of sexuality, HIV and AIDS education. This study sought to explore teachers’ experiences of using participatory visual methods in teaching sexuality education within the HIV and AIDS education programme in selected Kenyan secondary schools, in order to understand how such methods could affect the teaching of Sexuality education. This study employed a phenomenological research design, interpretivist paradigm and a participatory methodology. Memory accounts, reflective journals and focus group discussions were used for data generation with nine secondary school teachers, from three purposively selected schools in Kenya. Vygotsky’s socio-cultural theory underpinned the study. The findings revealed that teachers are uncomfortable teaching sexuality education because of fear of leading learners astray, fear of victimization and sexualization, and fear of misleading and hurting learners because of lack of knowledge. This resulted in teachers feeling guilty due to ineffective delivery of Sexuality education. The findings also revealed that participatory visual methods were effective for use by the teachers and the learners in the classroom to navigate issues around sexuality, HIV and AIDS. This was because they are learner-centred, thus making learners producers of knowledge while at the same time encouraging optimism in teaching and learning. This study thus recommends pre-service teacher training on participatory methods of teaching. Educational institutions should also arrange for workshops to train in-service teachers on comprehensive sexuality, HIV and AIDS education and how to tackle it in their classrooms.

- Description: The HIV and AIDS prevalence in Kenya is still high and remains a major health concern despite the Kenyan government’s initiatives to create awareness about the epidemic through inclusion of the HIV and AIDS programme in schools. This is because the provision of sexuality, HIV and AIDS education in schools is not effective. Teachers face various challenges in the effective delivery of the subject due to their discomfort related to these sensitive topics. Therefore, learners are left inadequately supported by the teachers. With an immense variety of conflicting information about sexuality availed to young people through the social media and also through their peers, young people are left at risk of exploring their sexualities with inadequate and wrong information, thus exposing them to HIV infections. Since schools have been identified as ideal sites for the effective delivery of sexuality, HIV and AIDS education, teachers are expected to teach the learners using a variety of pedagogical strategies in order to achieve efficacy in the delivery of this subject, hence the need to explore teaching styles that could provide a safe space for the effective delivery of sexuality, HIV and AIDS education. This study sought to explore teachers’ experiences of using participatory visual methods in teaching sexuality education within the HIV and AIDS education programme in selected Kenyan secondary schools, in order to understand how such methods could affect the teaching of Sexuality education. This study employed a phenomenological research design, interpretivist paradigm and a participatory methodology. Memory accounts, reflective journals and focus group discussions were used for data generation with nine secondary school teachers, from three purposively selected schools in Kenya. Vygotsky’s socio-cultural theory underpinned the study. The findings revealed that teachers are uncomfortable teaching sexuality education because of fear of leading learners astray, fear of victimization and sexualization, and fear of misleading and hurting learners because of lack of knowledge. This resulted in teachers feeling guilty due to ineffective delivery of Sexuality education. The findings also revealed that participatory visual methods were effective for use by the teachers and the learners in the classroom to navigate issues around sexuality, HIV and AIDS. This was because they are learner-centred, thus making learners producers of knowledge while at the same time encouraging optimism in teaching and learning. This study thus recommends pre-service teacher training on participatory methods of teaching. Educational institutions should also arrange for workshops to train in-service teachers on comprehensive sexuality, HIV and AIDS education and how to tackle it in their classrooms. Moreover, curriculum developers should make sexuality, HIV and AIDS education a compulsory subject to give it equal status with other examinable subjects, for it to be taken seriously. It is only through concerted efforts from everyone that Kenya can reach its target of Zero new HIV infections.

- Description: South African public schools in disadvantaged areas are experiencing serious levels of under resourcing which negatively impact the educational experiences of learners. Attempts to lessen such negative impact include involving alumni who know the school‟s context, history and ethos. Unfortunately, the concept of alumni support in terms of mentoring and motivating learners is not the norm in many under resourced schools. This research focuses on fostering partnerships with alumni using participatory action research (PAR), because it is holistic, relationally driven and inclusive. Embedded in complexity theory that views the school community as a nonlinear system of different interacting parts functioning to improve the school context, the research follows actionreflection cycles of a group of ten past pupils and five educators from various backgrounds, levels of education and expertise collaborating with and mobilizing other alumni. Data were generated using drawings, photo voice and interviews. Thematic data analysis was used to build patterns and form categories. The following themes emerged namely, the importance of establishing a collective vision for sustained alumni engagement for alumni‟s personal and professional aspirations to serve the vision of the school, the importance of creating an alumni culture that reinforces the concept of „paying it forward‟. Lastly, establishing a sustainable alumni association through sustained actions and interactions and by creating an organisation of excellence The newly developed alumni structure as a „resource fountain‟ generating and cascading energy around the school emerged as an anchor for sustainability. The cascaded energy evolved into a structured „Alumni Week‟ providing ongoing motivation for current learners to sustain alumni engagement.

- Description: The aim of this study was to explore and describe the intergenerational interactional patterns in a Coloured family where the mother has abused alcohol. Researchers have found that drinking behaviours of parents can have major effects on the children’s lives throughout generations. Substance abuse of a parent has major influences on the family, their interactions, and relationships, mostly between the parent and the child. There is a major gap in the study of the Coloured families and how substance abuse affects their families and children. The study employed Bowen’s constructs of differentiation of self, multigenerational transmission process, triangulation, emotional cut-off, nuclear family emotional system, sibling position, family projection process, and societal regression and utilized analytical generalization of the concepts to achieve its aim. The mother, an older sibling and maternal mother were the main sources of data although the perspective of the mother herself was privileged in the study. Semi-structured interviews were utilized to gather the data. This allowed participants to freely narrate their personal perceptions and experiences of interaction in both the family of origin and the current nuclear family. The research used a single case study of a purposively sampled family. The researcher is a Coloured female who had specific interest in this specific cultural group and their interactional patterns, which optimised cultural familiarity during the research process and reduced the likelihood of potential discriminatory racial bias of the participants. The findings demonstrate that perceptions of interactional patterns in the nuclear family and family of origin coincided with certain of Bowen’s Family Systems concepts, particularly, triangulation and differentiation. However, the need for further exploration of concepts such as the nuclear family emotional system and the family projection process in Coloured families are still needed in future studies. The findings provided insight into the functioning of the relationships and FAMILY INTERACTION IN MATERNAL ALCOHOL ABUSE interactions in both the nuclear family and the family of origin. Limitations of the current study are identified and recommendations for future studies in this field are also offered.

- Description: This thesis will analyse the ways in which fan participation and creation in online communities extends the film world beyond the film object, and the extent to which fandom influences identity within the fan group. The study will seek to determine the ways in which fans become part of the franchise through online engagement, as well as the manner in which they appropriate the franchise identity through their creations. The central hypothesis of the study is that online participation and creation amplifies fan connection with the film franchise, and increases the sense of identification with the world and characters of the films. By being or becoming fans, and engaging with other fans in online and real spaces, they are joining a larger community of people who seem to have blurred the lines between fiction and reality by engaging in a fictional, virtual space as a source of real personal entertainment, based on an anchor media product. This appropriation is enabled through digital communities which expand and extend the reach of fan interaction and further develop the identity of the individual as ‘fan’. Thus, the study will reflect on the implications of fan engagement with the film franchise in the digital space.

- Description: This study is focussed on female teachers teaching sexuality education in the HIV and AIDS curriculum in Zimbabwean urban secondary schools. In spite of the importance of education and HIV and AIDS education in preventing HIV infections, Zimbabwe secondary school Guidance and Counseling teachers are not engaging optimally with the current Guidance and Counseling, HIV and AIDS & Life Skills education curriculum, and hence, they are not serving the needs of the learners in the context of the HIV and AIDS pandemic. This study, therefore, explored the following research question with its set of secondary research questions: How can Guidance and Counseling teachers be enabled to teach sexuality education within the HIV and AIDS education curriculum suitable for the Zimbabwe secondary school context? What are Guidance and Counseling teachers’ understandings and interpretations of the current HIV and AIDS education curriculum in Zimbabwe secondary schools? What are Guidance and Counseling teachers’ values and beliefs that underpin their approach to teaching sexuality education within the HIV and AIDS education curriculum in Zimbabwe secondary schools? What do Guidance and Counseling teachers experience as challenges to teaching the necessary critical content in sexuality education within the HIV and AIDS education curriculum? How can Guidance and Counseling teachers be enabled to overcome the challenges they experience and teach the necessary critical content in sexuality education in the HIV and AIDS education curriculum? Eight female Guidance and Counseling urban secondary school teachers, conveniently and purposively selected from Gweru district in Zimbabwe, comprised the sample of participants. Situated within a qualitative research design, and informed by a critical paradigm, I used participatory visual methodology, with drawing and focus group discussion as methods for data generation. Participatory and thematic analysis was used to analyse the data which was theoretically framed by Cultural Historical Activity Theory, as a lens through which I explained the meaning of my findings. The findings, in four themes, revealed that the Guidance and Counseling teachers have an understanding of the Guidance and Counseling curriculum and made their voices heard on how it was designed but also how it should be designed, with whose input it should be designed and why, and how teachers should be supported in implementing it and ensuring that it is appropriate to the context in which they teach. The Guidance and Counseling teachers reflected on and reconsidered their own values and beliefs in relation to the values underpinning the sexuality education within the HIV and AIDS curriculum in order to fulfil their professional role in the context of the HIV epidemic. Even though the Guidance and Counseling female teachers were enthusiastic to teach sexuality education - in the age of HIV and AIDS - in the particular school and community context, they found themselves in an educational system that did not seem to support their work in an optimal way, and in a community with diverse cultures, cultural practices and beliefs of which some seemed to contradict what was supposed to be taught in the curriculum. The participatory visual methodology, however, enabled a process in which the Guidance and Counseling female teachers could reflect on themselves, the context in which they taught, their sexuality education work and also learn from each other. In this way their agency seemed to have been enabled to address the challenges and consider how they could teach sexuality education in their secondary schools in Zimbabwe. The findings have several implications for policy in terms of the Guidance and Counseling curriculum, resource mobilization, pedagogy, engaging with cultural issues, and supporting vulnerable children; and for practice in terms of teacher professional development, teacher training, and for stakeholder contribution. I therefore argue, drawing on Cultural Historical Activity Theory, that the Guidance and Counseling teachers could be enabled to teach sexuality education if the three Activity Systems, namely the Guidance and Counseling teachers, the school system, and the community, work together as one Activity System, engaging with each other in a generative way focused on the same outcome. The Guidance and Counseling teachers could therefore transform their realities if they are enabled to see how their teaching of sexuality education in school is linked to the context of the school and the culture of the community in which they teach and live, and engage with each other to achieve the same objective, namely teaching sexuality education in secondary schools in Zimbabwe, and in so doing enable the learners to make informed choices in the context of HIV and AIDS.

- Description: The research for this study was guided by the question on whether the financial inclusion improvement strategies of the South African government adequately address the financial inclusion targets, as set out in the National Development Plan. This descriptive non-empirical study was conducted by means of a literature review. The secondary data used for the study were collected from a number of sources, namely: (i) the 2015 Brookings Financial and Digital Inclusion Project report; (ii) the 2014 Global Findex survey; (iii) the InterMedia surveys; (iv) Financial Access surveys; (v) various national FinScope surveys; and (iv) a number of working papers of the World Bank related to financial inclusion. The data revealed that South Africa, with its sophisticated financial sector, was early to adopt policies and initiatives to advance financial inclusion and the country has experienced a noticeable increase in financial inclusion from 61% in 2004 to 87% in 2015. South Africa is 3% away from its National Development Plan goal of 90% financial inclusion by 2030. This indicates that overall, the financial inclusion initiatives adopted by the South African government were successful.

- Description: Although directives exist with respect to promoting sustainable development, financial strategies to cater for collective sustainable development, along with an increasing population, need to be formulated relevant to metropolitan and urban areas. This study determined the infrastructure investment basis of a sustainable city to investigate various funding mechanisms resulting in the design of a model for the financing of sustainable cities. For the study, first the various infrastructure investment alternatives were established from the literature, and thirteen themes and their relevant interventions were identified. Tangible and intangible methods of assessment were then identified as ways to calculate the acceptability of an intervention. A case study based on a hypothetical city was developed to determine the infrastructure investment base. Initially, only one intervention of a theme was populated and then confirmed by city development experts. Thereafter, all the themes were populated, and the acceptability of the interventions were determined. This provided an overview of the investment base of a sustainable city. The investment base facilitated deriving applicable tools and instruments to finance it. As a result, possible finance alternatives were derived for each of the identified themes. Although most of the financing of sustainable cities revolved around public sector finance, the private sector also played an important role for the financing of sustainable cities. Based on the investment base for sustainable cities and the resultant financing thereof, a model for the financing of sustainable cities was developed. The model consisted of four components. Firstly, the model included an application of financing tools and instruments relevant to the identified themes of sustainable city development. Secondly, the model included the application of financing tools and instruments with respect to an immediate interventionist focus, a facilitative focus, a gradual intervention and an enabling intervention. Thirdly, the model included financing tools and instrument types in terms of incentive, opportunity, punitive and mandatory interventions. Fourthly, the model included the application of financing tools and instruments with respect to scale in terms of a city-wide application, sector-wide application, urban application or suburban application. In addition, the model included the application of financing tools and instruments and their relation to addressing poverty within the city context. Although the public sector will always remain the key initiator behind infrastructure development, various mechanisms of financing, along with applicable financing partners and the basis of investment, are required to address future sustainable cities. This study may potentially form the basis of that platform.

- Description: This study empirically investigates the relationship between fiscal deficit, inflation, M3 money supply and the exchange rate in South Africa. The study makes use of quarterly macroeconomic time-series data sets comprising 84 observations, covering the period from 1994Q1 to 2015Q4. The unit root tests conducted employed the Augmented Dickey Fuller (ADF) and Phillips-Perron (PP) tests. The results reveal that the variables become stationary at first difference. The Johansen co-integration technique suggests that there is at least one co-integrating equation among the variables. The results of the Engle-Granger approach, which is residual based, show that the residuals are stationary, thus validating the existence of a long-run relationship between the model variables. The study carried out a Granger causality test. The results indicate that there is a strong Granger causal relationship between the variables (IF) and (FD). Another strong causal relationship emerges between inflation and money supply. The ECM model was employed to identify the speed of adjustment as a response to the departures from the long-run equilibrium path. The estimated coefficient of the ECM error term has the required sign and is statistically significant at the five per cent level of significance. The error term indicates a quick convergence to equilibrium. The study concludes that the dependent variable (FD) is jointly caused by all the independent variables in the long-run. The results of the variance decomposition of the variable (FD) to innovations resulting from IF, MS and RER indicate that own shocks remain the dominant source of total fluctuations in the forecast error of the variables. The findings of the study are efficient and reliable as the estimated model passed all the major diagnostic tests. By implication the findings suggest that the estimated model show high goodness of fit and is thus reliable for policy making. The study recommends a fiscal adjustment that will enhance economic growth. Additionally, a fiscal policy that will aim at identifying and mitigating other possible leakages that narrow the tax base should be considered.

The results of the Engle-Granger approach, which is residual based, show that the residuals are stationary, thus validating the existence of a long-run relationship between the model variables. The study carried out a Granger causality test. The results indicate that there is a strong Granger causal relationship between the variables (IF) and (FD). Another strong causal relationship emerges between inflation and money supply. The ECM model was employed to identify the speed of adjustment as a response to the departures from the long-run equilibrium path. The estimated coefficient of the ECM error term has the required sign and is statistically significant at the five per cent level of significance. The error term indicates a quick convergence to equilibrium. The study concludes that the dependent variable (FD) is jointly caused by all the independent variables in the long-run. The results of the variance decomposition of the variable (FD) to innovations resulting from IF, MS and RER indicate that own shocks remain the dominant source of total fluctuations in the forecast error of the variables. The findings of the study are efficient and reliable as the estimated model passed all the major diagnostic tests. By implication the findings suggest that the estimated model show high goodness of fit and is thus reliable for policy making. The study recommends a fiscal adjustment that will enhance economic growth. Additionally, a fiscal policy that will aim at identifying and mitigating other possible leakages that narrow the tax base should be considered.

- Description: Body size (Mb) determines an animal’s energy and water demands for thermoregulation. Sexual dimorphism in Mb is common across many species, but its physiological consequences (e.g. energy and water demands) remain poorly understood. In this study, I determined if the sexually dimorphic Cape Sugarbird (Promerops cafer)–males are up to 15% larger than females, show sex-specific foraging patterns and physiological responses. To determine intraspecific variability behavioural in response to temperature, I compared flower visitation rates between male and female Cape Sugarbirds at different times of the day, and among days that varied in maximum air temperature. A total of 1207 males and 561 females were observed. Female Cape Sugarbirds visited flowers more often and continued to feed especially on hot days. Males generally dominated flower resources throughout the day, except on hot days. I also compared physiological responses in EWL, RMR and Tb between males and females at high air temperatures. There were no significant differences between the two sexes. Aggression which was overlooked appeared to have a high influence on foraging behaviour of Cape Sugarbirds. These results suggest that female Cape Sugarbirds will be more prone to energy and water stress during hot and dry summers in the Fynbos region because of resource dominance by male Cape Sugarbirds. Endemic birds, such as the Cape Sugarbird, warrant a conservation priority, especially since they are the dominant pollinator of the Protea plants in the Fynbos biome. The findings of this study will provide insights into population persistence of Cape Sugarbirds in response to predicted heat waves and rise in global temperatures.

- Description: Marine top predators often occupy broad geographical ranges that encompass varied habitats. Therefore, a pre-requisite towards conserving these animals is to determine the components of their realized niche, and investigate whether a species is a specialist or a generalist. For generalist species, it is also necessary to understand if local specialisation occurs. Uncovering these components can allow us to build models of a species realized niche that may then be used to infer habitat use in unsampled locations. However, fully understanding the components of a marine top predators realized niche is challenging owing to the limited opportunity for in situ observations. Overcoming these limitations is a key step in marine top predator research. It will enhance our understanding of trophic coupling in marine systems, and aid in the development of tools to better study these predators in their dynamic environment. Seabirds, penguins (Spheniscids) in particular, are a group of animals for which investigating their realized niche is of vital importance. This is because numerous species face growing uncertainty in the Anthropocene, and in a time of rapid environmental change there is furthermore a need to better understand the potential use of these birds as indicators of ecosystem health. The aim of this thesis, therefore, is to investigate the foraging ecology of gentoo penguins (Pygoscelis papua) at the Falkland Islands. At the Falkland Islands, limited historical information exists regarding this species foraging ecology, with most information coming from a single location at the Falklands. As the Falkland Islands have the world’s largest population of gentoo penguins, elucidating factors influencing this population will have global relevance. Furthermore, historical information indicated potential competition with fisheries, and with prospecting for hydrocarbons and an inshore fishery, there is a need to understand the distribution of these birds across the islands. Penguins are also well suited to carry biologging devices allowing for in situ observations of inter and intraspecific interactions, as well as habitat specific interactions. In this study, I sampled birds over three breeding seasons, from four breeding colonies - chosen for their varied surrounding at sea habitat - across the Falkland Islands. I investigated the diet with stomach content and stable isotope analysis, the at-sea distribution with GPS and time depth recorders, and how these birds behaved at sea using custom made animal-borne camera loggers. Furthermore, I developed a method to recognise prey encounter events from back mounted accelerometers, using a supervised machine learning approach. As part of the first species specific description of diet at this scale for the Falklands, I revealed six key prey items for the birds: rock cod (Patagonotothen spp.), lobster krill (Munida spp.), Falkland herring (Sprattus fuegensis), Patagonian squid (Doryteuthis gahi), juvenile fish (likely all nototheniids), and southern blue whiting (Micromesistius australis). The use of animal-borne camera loggers verified that not only do gentoo penguins consume a diverse array of prey items, but they adopted various methods to capture and pursue prey, with evidence of birds following optimal foraging theory. Prey composition varied significantly between study sites with the at-sea distribution and habitat use of penguins reflecting that of local prey. Birds from colonies close to gently sloping, shallow waters, foraged primarily in a benthic manner and had larger niche widths. However, those at a colony surrounded by steeply sloping, deeper waters, typically foraged in a pelagic manner. Contrasting diet patterns were also prevalent from stable isotope data, and the niche widths of birds relating to both stomach content and stable isotope data were larger at colonies where benthic foraging was prevalent. Therefore, it was clear that surrounding bathymetry played a key role in shaping this species’ foraging ecology, and that at the population level at the Falkland Islands birds are generalists. However, at individual colonies some specialisation occurs to take advantage of locally available prey. I developed habitat distribution models - via boosted regression trees – which transferred well in time but poorly across space. Reasons for poor model transfer might relate to the generalist foraging nature of these birds and the reduced availability of environmental predictors owing to the limited range of these birds. I furthermore developed a method to identify prey encounter events that can also, to a degree, distinguish between prey items. This method will be a promising approach to refine habitat distribution models in future. These habitat distribution models could potentially contribute to marine spatial planning at the Falkland Islands. Footage from animal-borne camera loggers clearly showed that prey behaviour can significantly influence trophic coupling in marine systems and should be accounted for in studies using marine top predators as samplers of mid to lower trophic level species. Ultimately, flexibility in foraging strategies and inter-colony variation will play a critical role when assessing factors such as interspecific competition or overlap with anthropogenic activities.
