- Description: The problem of education in South Africa is neither specialization nor broad education. It is adopting the most suitable curriculum for the improvement of educational provision and increasing the ability to adjust to a constantly changing and evolving economic environment. The curriculum of commercial subjects is appropriate for the overall transformation of the South African society because it holds the progressive development of business and entrepreneurial advancement, thereby pepping up industrial and economic development. The intensity and expectations from schools in terms of good results had been so high that since the advent of the new democratic dispensation in 1994, massive budgetary allocations had been committed to the development of education. This study sampled six high schools from circuit one of the Mthatha District of the Eastern Cape Province of South Africa for the investigation into the performance Grade 12 Business Studies learners. The Study revealed that prior knowledge was the most significant factor in determining a good performance in Business Studies. The conclusion is that on the basis of the research findings the overall development of teaching and learning towards good performance in Business Studies by Grade 12 students can be possible if teachers and students are provided with the required resources.

- Description: The Baviaanskloof catchment is a semi-arid catchment located in the Cape Fold Mountains of South Africa. Little is known about the functioning of the complicated Baviaanskloof fluvial system and the role alluvial fans in the fluvial landscape. This thesis will contribute to field of geomorphology and, more specifically, to the field of fan morphometry by producing a standalone fan framework outlining methods to investigate the influence of external and internal control variables on alluvial fans. In this thesis, outcomes of the applied framework and case study are used to develop fan restoration guidelines for the Baviaanskloof Valley. The framework incorporates external and internal fan control variables at a valley-wide and local fan scale. External control variables include accommodation space, base-level change, and drainage basin inputs. Internal control variables include fan style, morphometry and fan channels. In order to apply the framework, fan morphometry data was required. This data was collected by creating a spatial plan of fans and basins in the valley. Outcomes of the applied framework include; an understanding of baselevel change on fans, relationships between fan basin characteristics and the fan surface and insight into fan channel processes. Results of the applied framework are investigated further using bivariate (correlation matrix) and multivariate (principle component analysis and regression analysis) analysis techniques. Significant relationships identified are: drainage basin area versus fan area, fan area and fan slope and drainage basin ruggedness and basin size. The primary outcomes of this thesis include an alluvial fan form-process framework, key considerations to be included in alluvial fan restoration projects and fan restoration guidelines. Contributions of this thesis to broader alluvial fan morphology science includes new insights into general fan literature by compiling a form-process alluvial fan classification framework to identify external and internal fan control variables and identify fan form. Additions have been made to Clarke’s (2010) evolutionary stages to describe stages 4 and 5 of fan evolution that has been adapted to describe fan evolution and differentiate between stages of mature fan evolution. This thesis has also contributed to the study of alluvial fans in South Africa, particularly in the Baviaanskloof Valley. The layout of the procedural guidelines and key considerations for an alluvial fan project provides a guide for rapid fan assessment for maximum cost and time benefits for stakeholders.

- Description: Large catfishes (Clarias gariepinus & Clarias ngamensis) are not exploited commercially in the Okavango Delta, Botswana. They however constitute a large proportion of the gill net fishery catch (23 %) albeit as by-catch, coming second after cichlids (70 %). Monthly experimetal gill net sampling over 8 years showed that C. gariepinus was the most abundant species in the Okavango Delta by mass making up 37 % of the catch composition by fresh weight. Despite the relatively high abundance of C. gariepinus in the Okavango Delta, its status has never been fully assessed. For this reason, this study aimed to assess the status of C. gariepinus in the Okavango Delta with the particular goal to determine if the species could support a directed commercial gill net fishery. Investigation of the effects of the flood pulse on abundance of C. gariepinus showed that variability in water levels was the major driver of population abundance for this species. Three biological variables: (1) catch per unit effort (CPUE); (2) % catch composition and (3) Shannon's diversity index (H') exhibited a negative and significant relationship with the flood index within a year. The variation in these variables was statistically significant between months. There was a weak positive relationship between water levels and the biological variables between years suggesting increase in productivity of the system at high water levels without a lag period. Age and growth were determined using sectioned otoliths. Edge analysis showed that growth zone deposition occurred during the drawdown period in summer when water temperature and day length were increasing. The maximum recorded age was 15 years. Growth of this species was best described by the linear models (y = 21.50x + 427.39 mm LT; r² = 0.35) for females and (y = 23.79x + 440.83 mm LT; r² = 0.38) for males. The von Bertalanffy growth model described growth as Lt = 10000(1- exp(-0.002(t + 18.07))) mm LT for combined sexes Lt = 10000(1- exp( -0.002(t + 18.50))) mm LT , for females and Lt =908(1-exp(-0.076(t+7.95)))mmLT for males. Age at 50 % maturity was attained in the first year of life. Spawning occurred throughout the year with an apparent peak between November and April. The mean total annual mortality rate (Z) was 0.25 per year. The mean annual natural mortality rate (M) was 0.20 per year and fishing mortality (F) was calculated at 0.05 per year. The life history strategy of C. gariepinus was in between the periodic and opportunistic strategies. Therefore management of this species should be aimed at maintaining a healthy adult population and age structure. Since a large portion of the Okavango Delta is already protected and most other parts are also inaccessible to fishers there are enough spatial refugia for the species and the status quo should be maintained. Under this scenario, there is no need for regulation of the current mesh sizes because the species is harvested after maturity and replenishment of exploited populations will always occur from other parts of the system. Per recruit analyses indicate that the current fishing mortality maintains spawner biomass at levels greater than 90 % of pristine levels. Therefore a commercial fishery may be established using mesh 93 mm to maximize yield with a rotational harvesting strategy. Close monitoring is essential to ensure that re-colonization of overexploited habitats does indeed occur. Recreational angling and commercial gill net fishing need to be separated on a spatial and temporal scale during the feeding run to minimize potential conflicts.

- Description: Northern Rockhopper penguin populations, Eudyptes moseleyi, are declining globally, and at Tristan da Cunha have undergone severe declines (> 90% in the last 130 years), the cause(s)of which are unknown. There is a paucity of data on this species in the South Atlantic Ocean, therefore their trophic ecology at Tristan da Cunha was studied, specifically focusing on diet, using stomach content analysis and stable isotope analysis (SIA), in conjunction with an analysis of diving behaviour, assessed using temperature-depth recorders. In order to evaluate the influence of gender on foraging, a morphometric investigation of sexual dimorphism was confirmed using molecular analysis. Additionally, plasma corticosterone levels were measured to examine breeding stage and presence of blood parasites as potential sources of stress during the breeding season. Northern Rockhopper penguins at Tristan da Cunha displayed a high degree of foraging plasticity, and fed opportunistically on a wide variety of prey, probably reflecting local small-scale changes in prey distribution. Zooplankton dominated (by mass) the diet of guard stage females, whereas small meso-pelagic fish (predominantly Photichthyidae)dominated diet of adults of both sexes in the crèche stage, with cephalopods contributing equally in both stages. Adults consistently fed chicks on lower-trophic level prey (assessed using SIA), probably zooplankton, than they consumed themselves indicating that the increasing demands of growing chicks were not met by adults through provisioning of higher- quality prey. SIA also indicated that adults foraged in different oceanic water masses when feeding for self-maintenance and for chick provisioning, thus temporally segregating the prey consumed for different purposes. It is possible that adults ‘selected’ these higher quality prey for themselves, or this may be a reflection of opportunistic behaviour. At Tristan da Cunha sexual dimorphism was observed in culmen dimensions (length, depth, width), with males having larger beaks and feeding on larger individuals of squid and fish than females. No sexual segregation in terms of foraging habitat (i.e. different water masses, based on ð¹³N or trophic level ð¹⁵N) during the breeding season or pre-moult period was revealed through SIA, and stomach content analysis revealed no sexual differences in prey species targeted. The results of SIA of feathers indicate that during the pre-moult period birds foraged in different water masses than during the breeding period. The fact that throughout the breeding season birds foraged in similar habitats suggests no intra-specific competition, despite both sexes feeding on the same prey.Birds were generally diurnal, daily foragers (12 – 16 hr trips), with extended trips (maximum duration 35.5 hours) and nocturnal diving recorded in a few individuals. Birds dived well within their physiological limits, predominantly utilising the upper 20m of the water column, employing two different strategies to target different prey items. Long, deep (30 – 40 m), energetically costly dives were performed when targeting energy-rich prey (fish), and a greater number of shorter, shallower (5 – 20 m), energy-efficient dives were performed when targeting prey with a lower energy content (zooplankton). More than half of the sampled study population were infected with the intra-cellular blood parasite Babesia, but infection showed no relationship to body mass, corticosterone levels or breeding success. Fasting birds showed no signs of elevated corticosterone levels, suggesting they had acquired sufficient fat reserves prior to breeding. Failed breeders did not exhibit elevated corticosterone levels. Tristan skuas, Catharacta antarctica hamiltoni, were observed to be a significant cause of egg and chick mortality. The absence of sex-based differences in foraging, and the absence of any signs of stress in relation to body mass, presence of Babesia or breeding stage, suggest that there are no obvious signs of high levels of stress or food limitations during breeding at Tristan da Cunha.

- Description: The focus on entrepreneurs as drivers of the economies of nations has catapulted them into the forefront of the local and international marketplace. This has led to a demand for entrepreneurial education and training resulting in a plethora of different and often divergent views. One commonality that has emerged is that entrepreneurship can be taught; although it cannot be taught in conventional and traditional ways. It requires a move from traditional education and training to more enterprising participative and supportive forms of business development. It requires investments of time, resources and support. Incubators are facilities that are engaged with entrepreneurs and offer a variety of support including education and training. This study has assessed the effectiveness of training offered by the Seda Nelson Mandela Bay ICT incubator. There has been limited research undertaken on entrepreneurial education and training in an incubator setting. This study followed the qualitative paradigm. The sample comprised of 10 small businesses at the Seda Nelson Mandela Bay ICT incubator. Empirical data was obtained by interviewing the owners of the small businesses using an interview schedule. Issues such as the most effective training programme, content that it contained, methodology used and quality of the facilitator and applicability of the training programme were explored. The study found that the small businesses were opportunity driven rather than necessity driven and that the incubator served as a bridging facility in moving the businesses from the informal sector to the formal sector. The content of the training programmes was found to be effective when a mix of both theoretical and practical is offered especially with an emphasis on the underlying entrepreneurial themes of confidence, persistence and uncertainty and so on. It also found that training programmes should be linked to the life cycle of the business and address the specific needs of the small business owner. The start-up phase requires very specific training. Most of the facilitators were found to be experienced and empathetic. However, only a few were using a wider range of preferred learning styles favoured by entrepreneurs such as role playing, simulation, brainstorming and problem-solving techniques. The study also found that when generic training programmes are offered there was less recall on the part of the trainees. The management team of the incubator is an important determinant of the success of the incubatees and it is recommended that they need to be well versed in their sector and have good networking skills. There is a strong link between the theoretical and the practical content of training programmes especially where the emphasis is more on the practical content. It is recommended that facilitators pay attention to their relationship with trainees as it is a critical success factor in the training programme. Training programmes offered over a period of time add more value to the incubatee. This might be because of the mentoring and counselling that is available after each training module is completed. Finally, more research needs to be undertaken on the quality and effectiveness of training programmes offered by incubators to small businesses.

A psychobiography of Friedrich Nietzsche

- Description: The primary aim of this psychobiography was to examine Friedrich Nietzsche’s life by utilizing Carl Rogers’ theory of the fully functioning person. Friedrich Nietzsche (1844 - 1900) has become an iconic figure in German philosophy and literature. Nietzsche’s criticism of western morality and culture led him to believe that humankind was not living to its highest potential and consequently Nietzsche sought after a life of self-becoming. Nietzsche’s philosophy has influenced various people such as Viktor Frankl, DH Lawrence, Michel Foucault and NP van Wyk Louw. Nietzsche was chosen as the research subject because of personal interest, his prominence as a philosopher, and because of his ambition to live a meaningful life. Psychobiographical research with the use of psychological theory allows for the exploration and description of the life of an individual. This significant area of research involving the application of psychological theory has in previous decades, however, been under-utilized, particularly in South Africa. But more recently, has it been receiving increasing support by researchers both internationally and in South Africa. Data collected on Friedrich Nietzsche’s life were drawn from several primary and secondary sources. A data collection and analysis grid was developed in order to collect data systematically, and to analyse the data according to the qualities of Carl Rogers’ theory. The study adds to the body of psychobiographical research. It also provides an empirical exploration of Carl Rogers’ theory of the fully functioning person. As the scope of the study was that of a master’s dissertation, future research, utilising semi-structured interviews with knowledgeable relatives, academics, psychologists, biographers, philosophers and historians on Nietzsche’s life, could extend this line of research. In conclusion, the current psychobiography suggests that Nietzsche lived a life filled with several personal crises. Despite these challenges, Nietzsche directed himself towards living as a fully functioning person. Nietzsche’s impetus towards self-becoming is also evident within his philosophical writings. Nietzsche was an extraordinary individual whose life, as described in the current psychobiography, corresponds closely to Rogers’ (1961) theory of a fully functioning person.

Friedrich Nietzsche (1844 - 1900) has become an iconic figure in German philosophy and literature. Nietzsche’s criticism of western morality and culture led him to believe that humankind was not living to its highest potential and consequently Nietzsche sought after a life of self-becoming. Nietzsche’s philosophy has influenced various people such as Viktor Frankl, DH Lawrence, Michel Foucault and NP van Wyk Louw. Nietzsche was chosen as the research subject because of personal interest, his prominence as a philosopher, and because of his ambition to live a meaningful life. Psychobiographical research with the use of psychological theory allows for the exploration and description of the life of an individual. This significant area of research involving the application of psychological theory has in previous decades, however, been under-utilized, particularly in South Africa. But more recently, has it been receiving increasing support by researchers both internationally and in South Africa. Data collected on Friedrich Nietzsche’s life were drawn from several primary and secondary sources. A data collection and analysis grid was developed in order to collect data systematically, and to analyse the data according to the qualities of Carl Rogers’ theory. The study adds to the body of psychobiographical research. It also provides an empirical exploration of Carl Rogers’ theory of the fully functioning person. As the scope of the study was that of a master’s dissertation, future research, utilising semi-structured interviews with knowledgeable relatives, academics, psychologists, biographers, philosophers and historians on Nietzsche’s life, could extend this line of research. In conclusion, the current psychobiography suggests that Nietzsche lived a life filled with several personal crises. Despite these challenges, Nietzsche directed himself towards living as a fully functioning person. Nietzsche’s impetus towards self-becoming is also evident within his philosophical writings. Nietzsche was an extraordinary individual whose life, as described in the current psychobiography, corresponds closely to Rogers’ (1961) theory of a fully functioning person.

- Description: It was the objective of this project to provide a glass cleaner formulation for a wet wipe application with cleaning and anti-fogging properties. This glass cleaner formulation was developed for automotive glass i.e. interior of windscreens. This formulation relates to a glass cleaner with a composition comprising of: (a) a blend of amphoteric surfactants; (b) a solvent system with a combination of glycol ethers; and (c) an aqueous solvent system. This glass formulation must provide good cleaning properties while also providing good wetting and sheeting properties to assist with anti-fogging properties. The objectives were obtained using 2 specific approaches: The first was by using a blend of 2 amphoteric surfactants in an alkaline medium, allowing the glass surface to become more hydrophilic which will also assist with reduction of surface tension on the glass surface. The second was by using the glycol ethers that have good coupling properties and surface tension reducing properties. The formulation was evaluated using commercial standard test methods as per the industry. A predictive model was successfully obtained for each of the five criteria that were evaluated using the 25 formulations derived from the statistical design. There were variables and variable interactions that were antagonistic for some of the criteria which were found to be synergistic for others. To achieve satisfactory cleaning, the fogging rating had to be compromised.

- Description: The medium for teaching and learning in South African universities is not the mother tongue of the majority of students and this has been reported to be a barrier to achievement (Department of Education, 2002). Poor English language skills, as well as poor discipline specific vocabulary knowledge, can lead to poor study techniques with the students resorting to rote learning as they are unable to interpret the recommended texts (Gow, Kember, & Chow, 1991; Shembe, 2002). In 2005 at the NMMU a significant difference was reported between the marks achieved for the Pharmacology 2 (ZCL2) module by English first language (EFL) students and the English second language students (EAL) (Boschmans & McCartney, 2005). These finding provided motivation for this study which interrogates issues of language and learning in a multilingual Pharmacology classroom. A mixed methods approach, which employed a concurrent triangulation design with quantitative dominance, was used. Two parallel studies were undertaken. One consisted of a quasi-experimental, pre-test and post-test control group design using an intervention which consisted of the application of the didactical practice of exploratory talk with an experimental sample group during ZCL2 Supplementary Instruction sessions (SI). A second study involved a parallel data collection from the ZCL303 and ZCL401 Pharmacy students at the NMMU to investigate possible effects of academic progression. Purposive, homogenous sampling was used in selection of the samples. The mean ZCL2 mark for the experimental group (58.70±14.14 percent) of students who experienced the intervention (application of exploratory talk) was significantly higher (p = .0004) than the mark achieved by the ZCL2 comparison group (46.47±14.48). This Abstract difference was of high practical significance (Cohen‟s d = 0.85). This quantitative finding was supported by the qualitative data where the students expressed support for the discussion sessions (application of exploratory talk) held during SI sessions. There was a significant increase, with academic progression, of English reading comprehension amongst the EFL students (p = .025) but not in the EAL students and BPharm1 weighted average (p < .001) as well as SI attendance (p = .02) correlated significantly with achievement in ZCL2. The findings of this study provide insights into the teaching of Pharmacology in a multilingual classroom. The qualitative results in addition to strengthening the quantitative findings through triangulation have provided a rich, deep and detailed description of the lived experiences of Pharmacology students. The data will provide insights into students‟ experiences for Pharmacy academics and are a resource for understanding student perspectives.

- Description: Information plays a vast contributing role to all resources within an organisation. Organisations should recognise the importance of information and implement information security controls to protect their information as this will ensure that the organisation‟s information retains its confidentiality, integrity and availability. Information security controls, which are the means of managing information risks, rely heavily on the user‟s knowledge regarding the use of these controls for their effectiveness, and as such, users should be educated in order to maximise effectiveness of these controls. Current information security educational programmes are created without necessarily taking into account the target audience, who comprises of all employees, stakeholders, suppliers, third parties, customers or other external parties or third party that requires access to the organisation‟s information. This results in programmes that are not linguistically appropriate; or that present knowledge at an inappropriate level for the target audience. This could leave users bored or confused, without successfully changing their behaviour or improving knowledge. This dissertation identifies a baseline for information security knowledge targeted at end users. This was done by means of a Delphi Study, where a profile of “generic” end users comprised of information security topics and concepts were rated by experts from the field of information security education. This resulted in the elimination of inappropriate topics and concepts and retaining the relevant and appropriate aspects. This baseline for information security knowledge can be characterised as a minimum standard that everybody should be educated on as an introductory or refresher course. This can also serve as the foundation phase to educate end users with knowledge of the basic topics and concepts to enable them to fulfil their responsibilities in order to protect information. If needed, topics and concepts could be added to the baseline for information security knowledge for specialised target audiences (e.g. specialised End Users, ICT Staff or Top Management).

- Description: This study investigates the economics of suicide in South Africa using the Mortality and Causes of Death data from death notification as well as regional economic data for the 2006-2008 period. Using an inflation rate that varies by month and across province of residence as a proxy for economic performance, the results indicate a negative relationship between inflation and suicide, suggesting that suicides are countercyclical. When controlling for month and province fixed effects, however, the inflation coefficient, albeit remaining negative, is no longer significant, except in the female sample. Suicide is more prevalent among younger individuals, while the greatest proportion of suicide is seen among men. Suicides also exhibit a strong seasonal variation, with peaks in spring and summer, with December having the highest suicide prevalence. The overall results indicate a negative but insignificant relationship between economic performance and suicide in South Africa, with socio-economic differences and individual characteristics accounting for most of the variation in suicide.

- Description: If you do not own the latest technology today it is thought that you are left behind in this technology driven age. More businesses use Self- Service channels to accommodate the increasing demands of customers. It has been said that the use of self-service channels can reduce input costs, increase efficiency and improve customer service. Unfortunately, many customers are left unsatisfied because retail banks are moving away from the human interaction when visiting a branch or advise customers to use their self-service channels, sometimes without any assistance. This causes customers to move banks, complain and in so doing reduce profits and customer relationships with their banks.This research’s main objective was to determine the impact of customer relationship management on retail banks that make use of self-service channels. A theoretical overview of self-service channels and customer relationship management was given. Advantages and disadvantages of each option were explored. The researcher wanted to explore the relation between customers using self-service channels and the assistance and protection provided by retail banks. The customer experience questionnaire used in this research asked retail banking customers from the South African population to determine how customers perceive and experience their banks’ self-service channels and customer service. Many questions relating to their needs and wants with regards to banking have been explored. The results show that most customers are satisfied with their banks in general but do feel that the banks can improve their customer service and assistance with regards to using self-service channels like ATM’s, online and telephone banking and E-Wallet. It has concluded that most customers choose their banks based on advertisements and other media, not customer service, product range or word-of-mouth. The general perception is that customers say that their bank charges do justify the customer service received.

- Description: Amongst other socio-economic challenges that South Africa has, unemployment still remains high; in July 2010 unemployment was at 25.3 percentage and in July 2011 it was at 25.7 percentage ; in a space of a year it grew by 0.4 percentage (Trading Economics, 2012). Even though South Africa has made some significant progress with its democracy; there is still significant socioeconomic problems. Poverty, lack of economic empowerment among the disadvantaged groups are amongst and lack of proper education are amongst some of these pressing challenges in South Africa. More than a quarter of South Africa's population currently receives social grants (Index mundi, 2011). The Eastern Cape Province is still faced with significant socio-economic challenges such as high unemployment rate. 74 percentage unemployed are the economically active group as they are under the age of 35 (ECDC, 2011:22). “More than a quarter (26.4 percentage) of households in the Eastern Cape relies on government grants as their main source of income. Nationally, the youth unemployment rate is estimated to be close to 35 percentage, with more than three million young people out of work. Youth unemployment in the Eastern Cape averages 41.4 percentage. This is more than twice the adult unemployment rate (18.4 percent). A total of 695,175 young people have been without work every year in the Eastern” (ECDC, 2010-2011: 23). Besides, this province has a third largest number of people who are living with HIV/AIDS in the country. These statistics have a major significance on the province’s economic prospects and progress (ECDC, 2010-2011:22). The RSA Constitution 1996, the White Paper on Local Government 1998 has mandated local governments to facilitate LED. South Africa adopted LED as a way of fighting poverty and stimulating economic growth and development for local residents. LED is promoting skills development, SMMEs and tourism to encourage economic development. However the success of LED has received mixed views in that; some successes of LED were recorded in urban or metropolitan municipalities. Few successes have been recorded of LED projects in rural municipalities. Some of the constraints of LED consist of capacity problems within the municipalities, understanding the role of LED in the municipality and lack of funding. In Makana Municipality, about 23 percentage of households live below poverty line of (R800.00 – R9600 a year). Most of the population earns between R801.00-R1600.00 per month with 24.7 percentage. A mere 0.6 percentage earn R204801.00 or more compared to 12.7 percentage with no income. Inadequate infrastructure poses as a threat to attracting and retaining investment in this municipality. In light of the above paragraphs, this thesis evaluated the impact assessment of the LED projects within Makana Municipality. The premise of this thesis is that realization and significant support of LED projects would impact positively on unemployment and poverty rate that this municipality is facing and subsequently; the burden of unemployment and poverty will be reduced in the region, province and country.

- Description: The goal of this research was to determine, in a South African context, whether there is any correlation between chief executive officer compensation and the performance of the company. For the purposes of the research , the compensation of chief executive officers was broken down into three components: salary, bonus and "other" remuneration, while company performance was measured on return on equity, return on assets and earnings per share figures. Studies on this topic have been carried out in other countries, most notably in the United States of America and the United Kingdom. It appears that no research of a similar nature has been carried out in South Africa. Data in respect of the forty largest listed companies in South Africa were collected over a period of five years. The econometric models used for the research were based on models identified in the literature study. The data were then analysed for evidence of a correlation between chief executive officer compensation and the performance of the company. The results of this study indicate that there is no linear relationship between chief executive officer compensation and company performance variables. The econometric models did, however, show correlations between certain variables, taking into account the other predictor variables in the model. Evidence of correlations between age and experience and compensation was also found , which may present potential avenues of research to scholars in the future.

- Description: Mammalian predators are keystone species and can have disproportionately large impacts, relative to their abundance, on the communities and ecosystems they inhabit. In addition, predator-prey interactions (including bottom-up and top-down effects) are the fundamental linkage among species in food webs. Thus, understanding the food requirements of predators is imperative. There have been no comprehensive studies on the diet of black-backed jackals (Canis mesomelas) across a full seasonal cycle in the Albany Thicket Biome of the Eastern Cape Province. This biome is rich in plant diversity, is highly nutritious for herbivores and supports a large number of mammalian species, yet it is poorly conserved. The aim of the present study was to establish the diet of black-backed jackals on two conservation areas where thicket vegetation dominates (Great Fish River Reserve and Kwandwe Private Game Reserve). The diet was assessed using scats collected monthly from June 2009 to May 2010 and a sample of 25 stomachs over the same period. At both sites and across all seasons, mammalian hair was encountered most often (93% of all scats) and a total of 23 mammal species were consumed. Of the mammals recorded in the scats, hair from several ungulate species was encountered most frequently and these were mostly hider species (offspring hidden in tall vegetation just after birth). On a seasonal basis, the proportion of mammalian hair was lowest in autumn. However, the contribution of fruits (Carissa haematocarpa, Diospyros lycioides and Grewia robusta) to the diet was significantly higher during this season. This suggests that black-backed jackals may employ diet switching in the Eastern Cape as a mechanism to capitalise on seasonally abundant food sources. Based on the stomach content analysis, invertebrates were consumed as frequently as mammalian prey throughout the year but mammalian prey was recorded in greater quantity (i.e. volume and mass). Thus, scat analysis may have overestimated mammalian prey and fruits and underestimated the importance of invertebrates, particularly highly digestible species (e.g. termites). In spite of these differences, scat analysis demonstrated similar general and seasonal trends as the stomach content analysis. Thus, scat analysis can provide an efficient and relatively accurate source of information on the diet of blackbacked jackals in the Eastern Cape. Both stomach content and scat collection methods depicted the black-backed jackal as a generalist and opportunistic predator, mainly relying on mammals and invertebrates. Although the results of my study suggest that black-backed jackal may be important predators of certain ungulate species, further study on their prey preferences, actual biomass ingested and the effects on the population viability of prey species is required in order to develop a robust management plan for the species in the protected areas of the Eastern Cape.

Environmental cues and sensory preferences directing the nesting process in loggerhead turtles, caretta caretta, nesting in Maputaland, South Africa

- Description: Animals use their senses for everything on an immediate, and day to day fashion – detecting danger, finding food, finding mates among other activities. In sea turtles and other migratory species senses are used for long-distance migrations. Senses such as smell, vision and hearing, have been studied experimentally under laboratory conditions but seldom have been investigated in the field. This thesis takes a combination of field and laboratory experiments and investigates some of the hypotheses involved in natal homing and nest site selection. The loggerhead’s nesting distribution in Maputaland is distinct with characteristic high and low density nesting areas which are consistent from year to year. Investigations by earlier researchers on these beaches suggested that beach characteristics, such as beach morphodynamic type and beach width, do not appear to influence the beaches at which loggerheads emerge to nest. The high density nesting area (with approximately 440 loggerhead emergences/km) have similar beach characteristics as the low density nesting area (with <50 loggerhead emergences/km). It is therefore suggested that there is another cue that drives nest site selection. It can either be related to a physical characteristic not yet realised, or is a non-physical (but chemical or biological) cue. This dissertation aims to identify the sensory inputs received during the nest selection process, as well as sea-finding ability after nesting. To investigate the mechanism causing the high-density as opposed to the low-density nesting area, three potential drivers were investigated namely: chemical imprinting (as a natal beach cue), ambient and artificial light (as deterrents) and social facilitation (as a learned behaviour). It was also attempted to identify the strength of the most common senses – vision, hearing and smell. As animal ethics restricts interfering with emerging or nesting turtles, the strengths of these senses were tested during sea-finding by adult loggerheads. The results indicate that sulfide concentrations appear to be used as chemical cues for nesting as these concentrations are elevated (>150 percent) in the high density nesting beaches compared to the low density nesting beaches within and among seasons however further investigations are required. Artificial light (range: 0.045–0.5 lux) is an active deterrent of female emergences while ambient light, even under extreme conditions such as lightning during electric storms (up to 8.2 lux), appears to have no observable influence on the spatial or temporal distributions of emergences. Social facilitation appears unlikely as a primary nest site selection factor for loggerheads. It may however, play a minor secondary role to preferred areas or hotspots. Sea-finding in post-nesting female loggerheads appears to be driven exclusively by visual cues such as the light horizon, with minimal to no influence from other cues (the sound of the breakers, slope or smell of the ocean) which solidify the visual system’s use in sea-finding. This research on the nest site selection of loggerheads and the sensory systems involved in this process has added valuable information to the limited pool of knowledge already present and has created a solid framework on which further investigations can be based. Future work in this field should focus on integrating a suite of sensory stimuli and cues to receive a greater understanding of the sensory systems used in nest site selection.

- Description: Production functions are common to any productive activity. Although it may not appear obvious, cricket is no different. Production functions in cricket provide a wide range of information, utilised to enhance efficiency and maximize match success. Given these benefits, this study involved the derivation of a production function for the South African SuperSport Series and an analysis of technical efficiency. An econometric analysis was conducted on data from the 2004-2011 cricket seasons and it was concluded that the most optimal strategy for South African teams involved a combination of attacking batting and defensive bowling. Furthermore, South African teams had a relatively low variable substitutability and a high degree of technical efficiency.

- Description: We find a solution to Einstein field equations for a regular toroidal lattice of size L with equal masses M at the centre of each cell; this solution is exact at order M/L. Such a solution is convenient to study the dynamics of an assembly of galaxy-like objects. We find that the solution is expanding (or contracting) in exactly the same way as the solution of a Friedman–Lemaître–Robertson–Walker Universe with dust having the same average density as our model. This points towards the absence of backreaction in a Universe filled with an infinite number of objects, and this validates the fluid approximation, as far as dynamics is concerned, and at the level of approximation considered in this work.

- Description: We define, by an integral of geometric quantities over a spherical shell of arbitrary radius, an invariant gravitational entropy. This definition relies on defining a gravitational energy and pressure, and it reduces at the horizon of both black branes and black holes to Wald's Noether charge entropy. We support the thermodynamic interpretation of the proposed entropy by showing that, for some cases, the field theory duals of the entropy, energy and pressure are the same as the corresponding quantities in the field theory. In this context, the Einstein equations are equivalent to the field theory thermodynamic relation TdS=dE+PdV supplemented by an equation of state

- Description: We calculate graviton n-point functions in an anti-de Sitter black brane background for effective gravity theories whose linearized equations of motion have at most two time derivatives. We compare the n-point functions in Einstein gravity to those in theories whose leading correction is quadratic in the Riemann tensor. The comparison is made for any number of gravitons and for all physical graviton modes in a kinematic region for which the leading correction can significantly modify the Einstein result. We find that the n-point functions of Einstein gravity depend on at most a single angle, whereas those of the corrected theories may depend on two angles. For the four-point functions, Einstein gravity exhibits linear dependence on the Mandelstam variable s versus a quadratic dependence on s for the corrected theory.

- Description: Research problem: The restructuring of an organisation can be classified as a transformational intervention (Litwin & Burke, 1992). As such is it has a potential to significantly influence key employee attitudes that are related to employee and organisational performance. Any deterioration in these attitudes could impact negatively on organisational outcomes. As part of the monitoring and review of change interventions, management needs to understand the change in employee attitudes towards their work and management in their business units and towards the broader organisation in order that, if necessary, corrective action can be taken. Research objectives: To address the research problem, research objectives and questions were established. The main objective of the study was to investigate whether there has been a change in attitudes of employees in two business units of a South African National Science Council after the implementation of restructuring in the organisation and the business units. The key attitudes to be measured are job and management satisfaction, perceived organisational support, organisational commitment and a dimension of employee engagement, dedication. Research questions: Four research questions were established and these were; What is the change in employee attitudes post-restructuring? In particular what is the change in employee job satisfaction; management satisfaction, employee engagement, commitment to the organisation and perceived organisational support? What is the relationship between the sub-groups, distinguished by gender, occupational level, race, home language, age, number of years of service and business unit, and employee attitudes pre-restructuring? What is the relationship between the sub-groups distinguished by gender, occupational level, race, home language, age, number of years of service and business unit, and employee attitudes post-restructuring? What is the relationship between the sub-groups distinguished by gender, occupational level, race, home language, age, number of years of service and business unit, and the change in employee attitudes pre and post-restructuring? Research design: The nature of this research is descriptive. In order to solve the research questions the researcher used a pre-test and post-test measurement of employee attitudes. A survey using a structured self-administered questionnaire was used to collect information regarding employee attitudes before and after the restructuring of the organisation and business units. Major findings: The results from the survey showed that there was a change in the levels of organisational commitment, job satisfaction and management satisfaction at the National Science Council after the restructuring had taken place. Also, the impact of the sub-groups in the organisation on affective factors was evident in the level of occupation and employee engagement, race and management satisfaction, the business unit and the levels of perceived organisational support, management satisfaction and employee engagement, home language and employee engagement, the number of years the employee had worked for the organisation and management satisfaction, age and job satisfaction and employee engagement.
