- Description: Cultural diversity in the workplace is the presence of multiple cultures or groups within the work environment. This diversity in culture can be as a result of a difference in origin or nationality, difference in society, difference in religion or a difference in tradition. A multinational company (MNC), also referred to as a transnational company is an organisation that is registered and operates in multiple countries but is managed from the home country. Today’s ever increasing rate of globalization and the expansion of organisations into countries other than their own has created workplaces where cultural diversity is the norm and where workplaces are no longer characterized by a single or monoculture. This study explores the cultural diversity of an Argentinian multinational company, My Multinational Company (MMC), operating in Argentina and South Africa. MMC is a market leader in the production, procurement and export of citrus products. There is a plethora of information on cultural diversity which identifies various factors which influence cultural diversity. The purpose of this study is therefore to enhance the current understanding of cultural diversity within a multinational company by identifying the factors which influence cultural diversity in a multinational company. The approach to this study is quantitative in nature and the paradigm to be followed is positivistic, based on an empirical study and questionnaire. The empirical study assesses previous work relating to cultural diversity and identifies the factors which influence cultural diversity. The questionnaire was developed from the literature and distributed to MMC employees in Argentina and South Africa in order to determine their similarities and differences. The results of the empirical study identified areas of improvement for MMC. Recommendations were then made based on the literature review and the analysis of the empirical results.

Factors influencing ecological sustainability in the ostrich industry in the Little Karoo, South Africa

- Description: The Little Karoo, situated in the Succulent Karoo biome of South Africa, has been heavily transformed by land use, and only 8.6% of the remaining natural vegetation is considered to be intact. There is ample evidence that the main cause of degradation is the overstocking of ostriches, an industry that has been the major economic driver of the area for more than 150 years. The ostrich stocking rate currently recommended is 22 ha.ostrich⁻¹. A literature review was used to examine the evidence, assumptions and rationale on which recommended and actually implemented stocking rates for ostriches are based. No experimental evidence using ostriches was found that supported the recommended stocking rate as either ecologically or economically sustainable. From the literature, there appears to be a wide gap between what are considered to be economically and ecologically sustainable stocking rates, with the implication that these two aims may be impossible to reconcile when practicing ostrich farming on natural veld. A comparison of recommended with actual stocking rates among land managers in the Little Karoo showed that all land managers far exceeded the recommended agricultural stocking rate of 22.8 ha.ostrich⁻¹. However, the stocking rates reported by land managers to the South African Ostrich Business Chamber were found to accurately reflect actual numbers determined when whole flocks had to be slaughtered after an outbreak of avian influenza. The recommended stocking rate appeared to be irrelevant to ostrich flock breeders and there appeared to be a trade-off between profitable ostrich farming and sustainable land-use practices. This study also investigated the attitudes and behaviour of ostrich farmers. It was found that environmental attitude is most likely the most important characteristic of a land manager to ensure positive conservation behaviour. This characteristic was most prominent in younger land managers with larger farms. The last component of the study integrated the context and complexity of the long term social, economic and ecological sustainability of this industry through the development of a logic model. The results showed a general lack of linkages between industry elements which impact on achieving sustainability targets. Greater collaboration between industry role-players, organized agriculture and conservation organizations is required to find a balance between utilization and conservation in the ostrich industry.

- Description: Collective bargaining was impacted by the confrontation at Marakina and the role players, employers and unions were left looking for new creative alternatives to reward operational employees (blue collar workers).Then, finding a well-designed pay system is crucial for the success of the organisation, since collective bargaining is under pressure. The following determinants, job based pay, performance based pay, skills based pay, education and training, and tenure based pay were constructed from literature to formulate the conceptual model for the pay of operators in the manufacturing sector of Port Elizabeth. There are a number of factors that are at play in the determination and design of pay systems, which need to be considered. Two major pay systems are at the centre of this study and they are those based on the worth of the job and those that are based on employees’ skills, productivity, education and training, and tenure. Pay equity is at the heart of employment relationship and is the reference point with regard to the distribution of resources when economic productivity and profitability are achieved. The findings presented indicated that all the determinants, job based pay, performance based pay, skills based pay and education and training, with the exception of tenure based pay, were significant to the pay of operational employees. However, the multivariable regression model found that job based pay is more significant and should be modelled as the foundation of the pay system for operational employees. Other pay determinants, such as performance and skills based pay are best modelled as additional increments that accelerate employees’ pay.

- Description: The study sought to investigate the factors influencing the contents of antiretroviral therapy (ART) reports in the Amathole Health District of the Eastern Cape Province. A qualitative and quantitative study was conducted to assess the challenges that inhibit this phenomenon. Structurally, the population consists of Amahlati and Nkonkobe sub-districts. Operational managers, information officers, professional nurses, data capturers, and administration clerks were randomly selected from sixteen facilities. Data collection was done on semi-structured interviews, questionnaires; observations were done using the probability sampling method, and the findings were analysed according to the same technique. The study revealed that the District Health Information System (DHIS) is the universal data management and reporting system which all healthcare and ART facilities are using to manage ART. However, regardless of all these universal arrangements such as the use of the DHIS to aid in reporting, the contents of ART reports from various facilities have not been uniform due to various factors. There is a lack of a reliable network to link DHIS computers across facilities. The shift from paper-based to electronic data management has caused the difficulties in the collating and management of ART data since some facilities are manual paper- based while others are automated using the modern DHIS. Lack of daily capturing and validation is a major challenge across the ART facilities. Further, there are Non-Governmental Organisations(NGOs) such as AFRICARE and the IYDSA that have signed a memorandum of understanding (MOU) with the district to provide a budgetary support for staff training in data management of ART reports in the district. While the NGOs keep on assisting the ART facilities with data management, there is a lack of skills transfer. The district could not account on follow-up of ART patients from one facility to another. This is increasing the number of defaulting in ART patients, thus there is no accurate figures on retention of patients in ART Programme. The officials from ART sites tend to use their own transport to carry data from facilities to the district offices and this resulted in late submission of reports. The study thus recommends that, inter alia, data management and trainings should be done to improve data quality in reporting, a reliable computer network be installed, backed-up and maintained for data and report management in the all healthcare facilities. All the ART sites should adopt and use the automated data management system for universality and eliminating the faults of manual paper data management and reporting. This would ensure that the contents of ART reports are uniform and a true reflection of the situation on the ground towards universal access to ART and healthcare in the Amathole Health District, and South Africa at large.

Factors influencing the choice of religion studies as a subject in the further education and training band: a case study of two schools within the Uitenhage District of the Eastern Cape Province

- Description: In 2006, a new subject, Religion Studies (RS), was introduced in Grade 10 as an optional subject. It represents a major paradigm shift in education of religion at the public school level. Minimal research has been conducted on the factors influencing the choice of RS in Grade 10 by the learners, subject advisors, principal and educators. This subject might constitute an “easy option” to boost the learner’s performance. Former or “recycled Biblical Studies” educators may be available or even volunteer to teach this subject or they may have to be absorbed within the system. Ethics, morals, cross cultural respect and non-discrimination are critical for the development of the South African democracy. While RS is optional, it could play a critical role towards achieving these outcomes. This study restricted its focus to the Uitenhage District of the Province of the Eastern Cape. After careful consideration, the interpretive approach seemed to offer the best access to the kind of knowledge the researcher desired. A theoretical framework, that narrowly links rational choice with cultural reproduction theory, can prove to be inadequate. This study would be deficient if it was restricted to the family or home factors. Peer influence, self-efficacy or ability, utility value, motivation and teacher or school factors have to be included. The case study approach was used for this research.Semi-structured interviews were used to obtain qualitative responses from learners, from principals and educators whose schools are offering Religion Studies, and from subject advisors with oversight of this subject. This study discovered, inter alia, that learners did not have a real choice but were led to believe that RS was compulsory. The school has an influential role on a learner’s subject choice. Parental participation fluctuated from active to passive guidance. Learners saw RS as an easy subject and an aggregate booster. The school community both informs and influences the subject choice of learners. The peer influence of friends and fellow learners also featured in subject choice. RS teaches about religion and culture, respect, catalyses moral development, is enjoyable and easy to study but requires extensive reading. The limited diversity in RS classes did not allow for this respect to be tested. RS can catalyse the development of moral values. Despite this subject being an aggregate booster, learners enjoyed RS and therefore do well. After balancing the “costs and benefits,” according to rational choice theory, learners choose subjects with a utility value for their future career. RS opens the possibilities directly and indirectly. The majority of learners said that RS will assist them in their career path, not only narrowly in religious and pedagogical vocations but also more widely. RS could assist in careers with constituencies of religious diversity, in the medical field, human resources and journalism. RS fosters citizenship, non-discrimination and the rounded development of the learner and these objectives have attracted educators to teach RS. Learners enjoy RS, have self-efficacy, their performance ranges from good to well. Educators have a positive view of RS and contend that RS fosters respect, analytical, critical, constructive and lateral thinking. Principals were introduced to RS when it replaced Biblical Studies and much confusion between the two has ensued. RS is inclusive and also catalyses the development of morals. Principals emphasised the ongoing need for retraining of teachers through refresher courses, workshops and seminars and an involved role of the Department. Retraining would prevent the RS educator from being an “ad hoc teacher.” The Department has failed to act proactively in the introduction of RS as a new subject. Challenges lie in the integration of learning, essay writing skills and developing good model assessment tasks. Understanding RS terminology, confusion of RS with Biblical Studies, a shortage of resources, the vast content and the subject related methodology of RS are other concerns. All the stakeholder groups confirm this misperception. Researchers also concur with this finding. Biblical Studies educators have no advantage in RS but rather also necessitate retraining. RS, as a new subject with low intake, was not afforded all the requisite support. The number of schools offering RS is static. Provincial officials also reflect confusion of RS and Biblical Studies. The lack of staffing of the subject specialist at the National or Provincial level office is perturbing. Based on this study of the factors influencing the choice of Religious Studies in the FET Band, the following recommendations were made: Steps should be taken to ensure that learners be given a real choice Sharing of detailed information about the unique nature and outcomes of RS including its critical engagement Informed stakeholder groupings e.g. parents, educators, principal, SGB, community, Provincial and National Department of Education should not abuse their influential role of support by overt or covert compulsion Clarity between spiritual formation and catalysing moral development Educators should continue to foster enjoyment of RS Steps to be taken to facilitate integration of learning, developing essay writing skills and encourage good assessment tasks Increase diversity in class so that respect can be tested More information be given about direct and indirect career pathing Need for continual re-training through refresher courses, workshops and seminars Steps to be taken to address inadequate resources of RS Despite the “flattering” results for RS, efforts need to be taken by all the stakeholder groupings to ensure that learner’s competencies become a means in which RS markets itself Concerted on-going effort be made to clarify the confusion between RS and Biblical Studies That the Department assumes a more engaged role in RS Steps be taken by all the stakeholder groupings to encourage religious diversity in the RS class The National Department of Education has to staff both the National and Provincial Offices with well-equipped and highly motivated leaders.

- Description: The study investigated the factors that lead to the high failure rate of grade 12 learners of the two high schools in the Ngqeleni area of Libode Mega District of the Eastern Cape, South Africa. The study was qualitative in nature; therefore interviews were used as the method of collecting data. Seven SMT members, four parents and four learners were, randomly selected from the two schools in the Ngqeleni area of Libode Mega District. The researcher randomly selected the participants then interviewed them. The researcher used a video recoder as an instrument to record the responses from the participants. To analyse data, the researcher transcribed the interview responses and interpreted them. The main findings of the study showed that the high failure rate was caused by the following factors: over-croweded classes, shortage of teaching and learnin~ materials, lack of parental involvement, teachers' low morale, poor learner discipline, teachers experiencing problems in implementing government policies, work-load and as such teaching becoming stressful. The researcher in his study therefore recommends that the Department of Education plans more workshops for schools to capacitate them. There should be provision for more classrooms and incentives for teachers. , Thesis (MMED) -- Faculty of Educational Sciences, 2019

- Description: Families form an integral part of society and in fostering individual well-being. Despite the acknowledged importance of family, the association between family functioning and individual well-being outcomes have remained unexplored in the current body of knowledge. This paper explores the association between family functioning and reported levels of life satisfaction and happiness in South Africa. The paper employs the Family Attachment and Changeability Index (FACI8) to measure family functioning, using data from the 2011 South African Social Attitudes Survey. Four measures of family functioning are utilised, namely the aggregate FACI8 scale, the attachment and changeability sub-scales, and family functioning type. Improvements in the level of family functioning as well as in the levels of attachment and changeability are positively associated with life satisfaction and happiness. In addition, individuals living in midrange or balanced family functioning types are more satisfied with life and happier compared to persons living in extremely or moderately dysfunctional families. The findings highlight the importance of supportive intra-family dynamics in fostering greater individual well-being. This in turn places emphasis on the investigation of likely correlates of family functioning and impact evaluations of family-focused social work interventions’ impact on family functioning as areas for future research.

- Description: Climate is an important factor of agricultural productivity and many rural dwellers in developing countries depend on agriculture and are highly affected by climate change and variability. The world is currently experiencing climatic changes and variability conditions which results in high temperatures, low rainfall patterns, shortage of water and drought persistence. Climate change and variability is affecting weather patterns and shifting seasons which results in serious repercussions on smallholder farmers. Smallholder farmers are extremely vulnerable to climate change and variability because their farming and production systems are climate sensitive and are not rebound to climate stresses. These adverse effects in developing countries arise from different climate change and variability-related causes, notable extreme weather events, food security, increased health risks in agriculture from vector home diseases, and temperature-related morbidity in environments. The study was carried in King Sabata Dalindyebo Municipality in the Eastern Cape Province in South Africa. This study examines farmers’ awareness of climate change and variability and its effects on agricultural productivity in King Sabata Dalindyebo municipality using a Descriptive Statistics, Binary and Ricardian Model fitted to data from a cross-sectional survey of 200 farmers in King Sabata Dalindyebo Municipality. Both primary and secondary data was used. This research study estimates the effects of climate change and variability on King Sabata Dalindyebo agricultural productivity using a continental dimension of Ricardian analysis. Results revealed that local farmers were aware of climate change and variability and perceived changes in average temperatures and rainfall. The changes in average temperatures and rainfall had adverse effects on crop and livestock production. However, farmers’ awareness of climate change is not to an extent that they presume adaptation to climate change as a necessity and crucial. The results show that climate change and variability affects farm income and there is a non-linear relationship existing between climatic variables (temperature and precipitation) and farm income which depicts U-shaped. The study results indicated that climate change and variability affect agricultural productivity and have an effect on agricultural productivity in King Sabata Dalindyebo Municipality. In view of the research findings, several policy proposals are suggested. The study findings suggest that climate change and variability must be taken seriously and monitored. Policy makers and government officials must support farmers with information distribution,education, market access, well trained extension agents, credit and information about mitigation strategies to climate change and variability which includes institutional and technological methods, particularly smallholder farmers.

- Description: In general there is very little research on the coping styles that the fathers of children suffering from Autistic Spectrum Disorder (ASD) use in order to cope with the day-to-day demands and stressors that result from their child‘s unique condition. The research study focuses on the fathers of children on the autistic spectrum and how they cope with the stressors resulting from their children‘s condition on daily basis. The study made use of Bronfenbrenner‘s Ecosystemic Theory of Human Development as the guiding theoretical framework in exploring and describing this specific research domain. This was a qualitative study and it was phenomenological, descriptive and analytical in nature. The reason for this was to hear the voices of the fathers and explore in-depth how they deal with the daily stressors resulting from their children‘s condition. Semi-structured interviews were utilised where the fathers were asked to respond to an open-ended question. The data that was obtained from the fathers was analysed by means of content analysis. The sample size of the study was small (n=5) and other limitations included a small number of previous studies done on the fathers of children on the autistic spectrum. The literature that is available that focused on the fathers of ASD children are often old and might possibly be out dated. However, this study aimed to hear the voices of the fathers of children on the autistic spectrum and explore how they cope with the daily stressors. Therefore, this study will contribute to the literature on the fathers of ASD children.

Specimens were collected up-current and down-current of a river mouth in 2 coastal regions ~50 km apart along southeastern South Africa during March and July of 2009. One of the rivers represents a marine-dominated system, and the other a freshwater-dominated system. Our aims were to assess any dietary differences among the 3 suspension-feeders, spatial changes in diet within each species (at regional and local scales—50 and 15 km, respectively), and temporal changes in diet within each species.

- Description: South Africa has a poor savings culture. This means that South Africans do not save enough income for a later stage resulting in a relative large number of South African consumers living in debt and using more credit than what they have saved. Almost half of the South African consumers were in debt during the year 2010 and had a negative credit record. Thus consumers in South Africa are not living only in poor conditions but are also open to exploitation by the informal economy. Lenders in the informal economy are known as ‘loan sharks’ because they charge consumers interest rates of between 40 and 60 percent. This is because low income consumers have less access to savings products and credit facilities from the formal economy. These factors are more prevalent among the black consumers, as they use informal credit providers. The sources of credit for black consumers in the informal market are social networks such as friends and family. Furthermore, black consumers have low levels of knowledge regarding issues such as bad debts. Black consumers are also more likely to experience financial problems than other racial groups. This means that black consumers may need to improve their levels of financial knowledge, financial skills and adopt positive financial attitudes to manage their financial problems without obtaining more debt. Thus, financial education may be the way of ensuring that black consumers improve their financial decision-making ability and their financial behaviour. Therefore, the purpose of this study is to investigate the relationships between financial literacy, financial inclusion and financial behaviour among the black community in Nelson Mandela Bay. To achieve the purpose of this study, a literature review was conducted on financial literacy, financial education, financial inclusion and financial behaviour. This was followed by an empirical investigation to establish the relationships between financial literacy, financial inclusion and financial behaviour. In this study, a quantitative research approach was adopted as necessitated by the purpose of this study and also to be able to collect a vast amount of perceptions from the black community. The sample of this study consisted of low to middle income black consumers living in Nelson Mandela Bay.

- Description: Surf-zone fish communities and their shifts over time are generally poorly understood. The aim of this study was to compare the current surf-zone fish assemblage at King's Beach, South Africa, to a similar study conducted three decades ago, before the collapse of many exploited shore fishes in the region. Beach seine nets (mesh sizes of 10 and 50 mm) were used to target juvenile and adult fishes bimonthly from February to August 2011 over the high tide around sunset. A total of 14 species were recorded in both the 30 m and 100 m seine nets. The catch in these seine nets was dominated by Pomadasys olivaceus and Liza richardsonii, and this was significantly different to three decades ago, when P. olivaceus, Sarpa salpa and Diplodus capensis dominated the catch. Important linefish species belonging to the Sparidae and Sciaenidae families were significantly smaller and less abundant in this study. Two sparids, S. salpa and Lithognathus mormyrus, which made a large contribution to the surf-zone catch three decades ago were absent during this study. Reasons for the significant shifts in the surf-zone fish community, including overexploitation of the linefish and potential habitat modification, are discussed.

- Description: Herbivory is a key process that mediates the abundance of primary producers and community composition in both terrestrial and aquatic ecosystems. On tropical coral reefs, changes in herbivory are often related to phase shifts between coral-dominance and dominance by seaweeds, or foliose macroalgae. Resilience or capacity to resist and reverse such phase shifts is, therefore, viewed as a critical function on coral reefs. This thesis used grazer exclusion and assay experiments at six sites within three different fisheries management regimes in Kenya to identify the impacts of herbivores (sea urchins and fishes) on algal dynamics in the context of coral reef resilience. First, I examined the grazing rates necessary to prevent phase shifts by quantifying consumption and algal production. Here, I found that, over a 390-day experiment, at least 50 percent of algal production must be consumed to avoid accumulation of algal biomass. Using video observations, I also showed that scraping parrotfishes remove more algae (per unit of fish biomass) than previously assumed, and that sea urchins, if released from predation, have similar impacts to fishes. Then I focused on algal succession, and found that sea urchins and fishes have different effects that are mediated by their abundances and species composition. Where sea urchins were less abundant and parrotfishes absent (e.g. young fisheries closures), progression of algae from turfs to early and then late successional macroalgae occurred rapidly and within 100 days. I then turned my focus to the removal of already established macroalgae (grown for > 1 yr in the absence of herbivores) and showed that sea urchins and browsing fishes were able to remove significant amounts of macroalgae where either herbivore was abundant. However, using multiple-choice selectivity assays and in situ video recordings, I found that browsing fishes fed very selectively with low overlap in diet among species, leading to low functional redundancy within a high diversity system. Finally, using long-term survey data (from 28 sites) to build a 43-year chronosequence, I showed that it is possible that the effects of herbivory will not be constant across transitions from open fishing to fishery closures through non-linear grazing intensity. Therefore, increases in herbivory within fisheries closures may not be immediate and may allow a window of opportunity for algae to go from turf to unpalatable macroalgae until scraping and browsing fishes fully recover from fishing (~ 20 years). The findings in this thesis are novel and raise concern over the potential implications of the slow recovery of parrotfishes or, given lower than expected functional redundancy in grazing effects, the absence of even one browsing fish species in fisheries closures. Overall, this thesis highlights the importance of herbivore community dynamics in mediating interactions among algae, and provides new insights for conservation and management actions that attempt to bolster the resilience of coral reefs.

- Description: Achieving food security in a ‘perfect storm’ scenario is a grand challenge for society. Climate change and an expanding global population act in concert to make global food security even more complex and demanding. As achieving food security and the millennium development goal (MDG) to eradicate hunger influences the attainment of other MDGs, it is imperative that we offer solutions which are complementary and do not oppose one another. Sustainable intensification of agriculture has been proposed as a way to address hunger while also minimizing further environmental impact. However, the desire to raise productivity and yields has historically led to a degraded environment, reduced biodiversity and a reduction in ecosystem services (ES), with the greatest impacts affecting the poor. This paper proposes that the ES framework coupled with a policy response framework, for example Driver-Pressure-State-Impact-Response (DPSIR), can allow food security to be delivered alongside healthy ecosystems, which provide many other valuable services to humankind. Too often, agro-ecosystems have been considered as separate from other natural ecosystems and insufficient attention has been paid to the way in which services can flow to and from the agro-ecosystem to surrounding ecosystems. Highlighting recent research in a large multi-disciplinary project (ASSETS), we illustrate the ES approach to food security using a case study from the Zomba district of Malawi.

As achieving food security and the millennium development goal (MDG) to eradicate hunger influences the attainment of other MDGs, it is imperative that we offer solutions which are complementary and do not oppose one another. Sustainable intensification of agriculture has been proposed as a way to address hunger while also minimizing further environmental impact. However, the desire to raise productivity and yields has historically led to a degraded environment, reduced biodiversity and a reduction in ecosystem services (ES), with the greatest impacts affecting the poor. This paper proposes that the ES framework coupled with a policy response framework, for example Driver-Pressure-State-Impact-Response (DPSIR), can allow food security to be delivered alongside healthy ecosystems, which provide many other valuable services to humankind. Too often, agro-ecosystems have been considered as separate from other natural ecosystems and insufficient attention has been paid to the way in which services can flow to and from the agro-ecosystem to surrounding ecosystems. Highlighting recent research in a large multi-disciplinary project (ASSETS), we illustrate the ES approach to food security using a case study from the Zomba district of Malawi.

- Description: This thesis focuses on the labour process within the minibus taxi industry in East London, South Africa. This industry is structurally situated within the informal sector or economy but is marked by contradictory processes of formalisation and in-formalisation. Though the taxi industry seems to straddle the formal and informal economies in South Africa, the study is conceptually framed in terms of the informal sector but in a critically-engaged fashion. The very distinction between formal and informal economies, whether in South Africa or elsewhere, is open to dispute; and, even if accepted, there are differing conceptualisations of the relationship between the ‘two’ economies. Also, the conceptual clarity of the term ‘informal economy’ has been subject to scrutiny, given the vast range of activities it is said to incorporate. While the distinction between formal and informal economies may be a useful conceptual starting-point, this thesis demonstrates that it is analytically useful to speak of degrees and forms of formalisation and in-formalisation along a continuum, rather than to dichotomize economies. The thesis therefore analyses in depth the competing and tension-riddled processes of formalisation and in-formalisation in the minibus taxi industry, and with a specific focus on the labour process.

- Description: The feasibility of incorporating efavirenz (EFV) into innovative solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) using the hot high-pressure homogenization (HHPH) technique was investigated in an attempt to address the shortcomings in therapy associated with the use of conventional dosage forms. The shortcomings include the unpalatable taste of API in solution, instability in the presence of light when in solution and psychiatric side effects of the API. In particular, sustained release approaches may reduce or limit the incidence of adverse psychiatric effects of EFV and alleviate Acquired Immune Deficiency Syndrome (AIDS)-related complications such as AIDS Dementia Complex (ADC) in patients, ultimately improving their quality of life. Prior to initiating pre-formulation, formulation development and optimization studies of EFV-loaded SLN and/or NLC, Response Surface Methodology (RSM) in conjunction with central composite design (CCD), was used to develop and validate suitable methods for the quantitative determination of EFV in pharmaceutical formulations and for monitoring EFV release from SLN and/or NLC in vitro. Simple, accurate, precise, sensitive and stabilityindicating reversed phase-high performance liquid chromatography (RP-HPLC) methods with UV and electrochemical (EC) detection were developed, validated and optimized for in vitro analysis of EFV in formulations. On the basis of risk-to-benefit ratio the RP-HPLC method with UV detection was selected as the most suitable for the quantitative determination of EFV in pharmaceutical formulations, and was applied to in vitro release studies of EFV from SLN and/or NLC. Pre-formulation studies were undertaken to investigate the thermal stability of EFV so as to facilitate the selection of lipid excipients for the manufacture of nanocarriers, and to establish their compatibility with EFV. It was found that EFV was thermostable up to a temperature of approximately 200°C, indicating that HHPH could be used for the manufacture of EFV-loaded SLN and/or NLC. Lipid screening revealed that EFV is highly soluble in solid and liquid lipids, with glyceryl monostearate and Transcutol® HP showing the best solubilizing potential for EFV. Glyceryl monostearate exists in a stable β-modification prior to exposure to heat, but exists in the α-polymorphic modification following exposure to heat. It was established that the addition of Transcutol® HP to glyceryl monostearate revealed the co-existence of the α- and β’-polymorphic modifications, thereby revealing the existence of the modifications in NLC produced from the optimum lipid combination. Furthermore, an investigation of binary mixtures of EFV/glyceryl monostearate and glyceryl monostearate/Transcutol® HP, in addition to eutectic mixtures of EFV, glyceryl monostearate and Transcutol® HP, revealed no interaction between EFV and the lipids selected for the production of the nanocarriers. Due to the significantly higher solubility of EFV in Transcutol® HP than in to glyceryl monostearate, NLC are most likely to have a higher LC and EE than SLN. In addition, the existence of both the α- and β’-polymorphic modifications in the binary mixture of the lipid implies that EFV expulsion on prolonged storage is unlikely to occur from NLC when compared to SLN. Consequently formulation development and optimization studies of SLN and NLC were performed to investigate the potential to deliver EFV from a novel technology with an appropriate LC and EE for EFV. Tween®80 was selected for use in these formulations as the use of this surfactant facilitates the targeting of nanocarriers to the CNS. RSM in conjunction with a Box-Behnken Design (BBD) was used to establish the effects of process variables, such as number of homogenization cycles and pressure, in addition to formulation variables such as amount of EFV and Tween®80 on the particle size (PS), polydispersity index (PDI), zeta potential (ZP), visual assessment (VA) and release rate (RR) of EFV after 24 hours. In addition the LC and EE, degree of crystallinity and lipid modification, shape and surface morphology of the optimized batches were investigated to ensure that EFV-loaded SLN and NLC of desirable quality were produced. On the day of manufacture the mean PS and PDI of EFV-loaded SLN was 59.00 ± 23.16 nm and 0.382 ± 0.054 respectively. The mean PS and PDI of EFV-loaded NLC was 34.73 ± 0.7709 nm and 0.394 ± 0.027 respectively. The formulations were in the nanometer range and exhibited a narrow particle size distribution, as indicated by the PDI values. The ZP values for optimized SLN and NLC generated on the day of manufacture using HPLC grade water as the dispersion medium were -32.5 ± 4.99 mV and -22.4 ± 3.72 mV respectively. In addition the optimized batches of SLN and NLC revealed a decrease in crystallinity in comparison to bulk lipid material. DSC, WAXS and FT-IR revealed that EFV was molecularly dispersed in the nanocarriers. In addition EFV-loaded SLN existed in a single α-polymorphic form, whereas EFV-loaded NLC exhibited the co-existence of α- and β’-polymorphic forms. Generally SLN and NLC were spherically shaped when viewed under transmission electron microscopy (TEM) and scanning electron microscopy (SEM). On the day of manufacture the EE and LC of EFVloaded SLN was found to be 96.77 ± 0.453 % and 9.68 ± 1.772 % respectively. The EE and LC of EFV-loaded NLC was 99.93 ± 0.413 and 9.995 ± 0.672 respectively. The release profiles for the optimized formulations of SLN and NLC exhibited an initial burst release over the first 0-3 hours of testing, after which the release was sustained for up to 24 hours. The cumulative % EFV released over 24 hours was higher from SLN (91.5±3.423 %) than that observed for NLC (73.6±4.34 %). Stability studies performed for 8 weeks on the optimized batches of the SLN and the NLC were also conducted so as to ensure product quality. The formulations were assessed in terms of parameters considered benchmarks of stability, and included ZP, PS, PDI, LC and EE. Generally these parameters remained unchanged following storage for 8 weeks at 25°C/60% RH but showed considerable changes following storage for 8 weeks at 40°C/75% RH. These studies reveal that SLN and NLC when stored at 25°C/60% RH have the potential to be used as colloidal delivery systems for EFV that have the potential to protect EFV from photodegradation and sustain release into brain tissue. The latter will ultimately reduce or limit the incidence of adverse psychiatric effects and potentially alleviate AIDS-related complications such as ADC in patients with HIV/AIDS, ultimately improving their quality of life. , Thesis (MSc) -- Faculty of Pharmacy, Pharmacy, 2014

- Description: South Africa has experienced three significant curriculum reforms since 1994. The first of these replaced the ‘apartheid’ curriculum with C2005 based largely on Outcomes Based Education. In the second stage C2005 gave way to the National Curriculum Statements, a simplified version of C2005. Finally, the NCS was replaced with CAPS. This research study investigates the perceptions, attitudes and experiences of teachers implementing these curriculum changes. It focuses in particular on Foundation Phase in 2012, the year in which CAPS was implemented in that phase. It took the form of an interpretive case study, using qualitative data generating and analysis techniques. Principals and selected teachers of two primary schools in Grahamstown – an ex-Model C school and a performing ‘township’ school - were the respondents of the study. Data were generated chiefly through questionnaires and semi-structured interviews, supplemented by document analysis and observation. The findings revealed that the teachers in this study are frustrated and angry about the frequency of curriculum change in South Africa. Respondents are particularly critical of OBE and the NCS. While they welcome the need for a departure from ‘apartheid’ curricula, they feel the pedagogical underpinning of the NCS – with its emphasis on learner-centredness – disempowered them as teachers. Hence, they welcomed CAPS which seems to return to content – rather than skills and attitudes – and re-instates the teacher as the chief giver of knowledge and manager of learning.

- Description: This dissertation deals with the nature of the black middle-class assimilation in the South African suburban space, a space that was the sole preserve of the white middle-class during apartheid. It explores the relationship between these races as they come to meet in this space and what new identities are being formed. It also explores the relationship between both the black and white suburbanites and the urban poor who stay in an adjacent area to the suburb. The study uses the Beacon Bay area, which is constituted by one of East London’s most affluent suburbs and a poor township, Nompumelelo, to show how the emergent black middle-class has managed to enter this space in the post-apartheid era. Previous studies by Richard Ballard (2004) and Grant Saff (2001) have shown how the white middle-class has always been against any form of race or class mixing. Within the suburb, the new black suburbanites in Beacon Bay appear to have been welcomed but with conditions by their fellow white counterparts. The relationship between these two races does not stretch beyond meet and greets and it is only in the second generation black middle-class that you find better and non-superficial relations with fellow white suburbanites. In the older generation, the generation that experienced apartheid, the relationship between these two races has been that of tolerance and serious escape of contact unless when necessary. The children of both white and black families, though, have a far better relationship in school and in sport than their parents. This has created another area of contact for both these races and it bears potential for meaningful integration in the suburban space. Externally as it relates to relations between the black middle-class and the urban poor, the findings show that these new black suburbanites express a similar discomfort as the white suburbanites about the urban poor’s presence in the area. This shows that the evolution of the Beacon Bay suburb, with its deep-rooted discourse of white middle-class exclusivity, has not been entirely about hatred of the urban poor necessarily but about an identity ascription of what it means to live in a suburb. Despite these realities traditional ceremonies organised by the black middle-class in the suburbs and the church appear to be playing a role in creating relations between these suburbanites and the Nompumelelo residents. This is why we have decided to use the conceptualisation of the 18th century frontier zone as the borders of segregation within the suburb and between the suburban residents and those of the township can be crossed and re-crossed.

- Description: A lack of fundamental movement skill (FMS) proficiency in children can contribute to decreased physical activity (PA) levels, increased adiposity and poor acquisition of specialised sport specific movement skills. To prevent the latter, the identification of FMS status in early and middle childhood years is needed for targeted and specific interventions. Against the backdrop of physical education being omitted from the South African school curriculum, the presence of a patriarchal society, gender sporting stereotyping, high levels of unemployment and low education levels; the assessment of FMS status is particularly warranted. Aim of Study: The primary aim of this study was to assess the FMS proficiency of girls aged 9-to-12 years from previously disadvantaged communities within Nelson Mandela Bay. Methodology:A descriptive-exploratory-contextual study design, employing quantitative assessment techniques, was utilized. The sample comprised of 227 girls. Convenience sampling was employed. Testing consisted of FMS proficiency tests in the 20m and 40m sprint, standing long jump, throwing for distance, catching, static balance and throwing for accuracy. FMS process scores were assessed with the body component (BC) and Test of Gross Motor Development II (TGMD II) approaches. Anthropometric measurements of the standing and seated height, mass, arm span and leg length were additionally measured. Microsoft Excel® and Statistica® were used for descriptive and inferential statistical analysis. In the case of significant ANOVA results, the Scheffe post hoc test was used for pairwise comparisons. Statistical significance was set at p<.05 and practical significance (Cohen’s d) was set at d>.2. Pearson Correlation Coefficient identified statistical and practical correlations between two variables and chi square was applied to indicate differences in frequency distribution tables. Cramer’s V values were applied to determine practical significance in the case where statistical significant differences were identified between sets of frequency distributions.
