- 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: Embelia tsjeriam-cottam Roem and Schult A. DC. (Myrsinaceae), popularly known as Vaividang, is a vulnerable forest species because of the high demand of fruits for medicinal purposes. It is in great demand in ayurveda and the pharmaceutical industry (>100 t/yr), which has imposed tremendous pressure on some natural populations. The fruits contain embelin (a benzoquinone derivative), which has wide clinical applications. Considering the importance, growing use and decreasing populations in some areas of its natural habitat, a study on development of sustainable harvesting practices of E. tsjeriam-cottam fruits was conducted in Chhattisgarh, in central India. Experiments were laid out in Dhamtari, Marvahi and Bilaspur forest divisions of the state covering both protected and open forests in a randomized design with three replications. At each site, quadrats of 40 × 20 m were laid out to study the effect of two fruit harvesting methods and four harvesting intensities on fruit yield, and regeneration of the species. Fruits were analyzed for their embelin content by HPLC method. This study is the first to experimentally assess the consequences of harvesting of E. tsjeriam-cottam fruits from India. It was found that up to 70% fruits could be hand plucked at the right time of maturity (December) to obtain quality produce without impacting the current population size. Since every year is not a good fruiting year, it is difficult to develop universal harvest regime for sustainable management of E. tsjeriam-cottam. The embelin content increased as fruits ripened, ranging from 1.01% to 5.63%. The adoption of sustainable harvesting practices will be helpful in sustainable management of E. tsjeriam-cottam and also provide income and livelihood opportunities to rural people on a sustainable basis.

- Description: South Africa is a nation of strangers, an uneasy mishmash of heterogeneous economic groupings, cultures and languages, a nation of marginalised minorities awkwardly pasted together. Numerous attempts have been made by its government to define and bolster a sense of nationalism and to create a sense of cohesion; however, a shadow side of this appeal for national identity has been the rise in xenophobic violence precipitated by the steady influx of refugees into the country. The title of this article is drawn from Albert Camus’s introduction to his disarming novella of dislocation, L’Etranger (1942), and I would like to explore some of the philosophical implications of representing strangers in different ways. Drawing on works by Zygmunt Bauman, Georg Simmel and Julia Kristeva, I will consider ambivalences towards the stranger represented in Magnet Theatre’s production (2010) of Die Vreemdeling [The Stranger], and pose a few questions about our relationship with the unknown. Attempts to familiarise the constituents of various communities with aspects of each other’s strangeness is a project which has typified much South African theatre in the past; and yet this is an approach which stands in sharp contrast to the importance granted processes of defamiliarisation first proposed so succinctly by Victor Shklovsky in 1917. Instead of attempts to harness and explain the unfamiliarity of others in order to communicate diversity, a celebration of the grandeur of the stranger may provide a more enriching alternative.

- Description: This work reports on the synthesis of new coreshell quantum dots (QDs)-low symmetry phthalocyanines conjugates. The energy transfer from QDs (donor) to phthalocyanines (acceptor) was investigated when the two are mixed together or chemically linked to each other. Ti monocarboxy phthalocyanine QDs-linked and Sn monocarboxy phthalocyanine QDs-linked gave the smallest centre-to-centre separation distance (r) corresponding to their higher Förster resonance energy transfer efficiencies which are estimated at 0.76 and 0.85 respectively. Higher energy transfer behaviour was achieved for all the covalently linked conjugates compared to their corresponding mixed counterparts. An improvement in triplet quantum yields and lifetimes was achieved for all the complexes in the presence of quantum dots, with the linked counterparts displaying excellent triplet state behaviour.

- Description: I like Allan Kolski Horwitz. He’s done great things for independent publishing in South Africa. Through his company, Botsotso, he’s probably responsible for publishing more poetry, prose and drama than any single person in the country today. The industriousness of his one-man operation has generously sponsored and nurtured thousands of pages of local literature over the course of many years. This is why it makes me so uncomfortable to say that I really don’t like this play. It gives me no pleasure to write a negative review, and especially not about books written by people I like. If I hadn’t already committed myself to writing this review, I would have avoided it. Nevertheless, I had, so I won’t.

- Description: The syntheses of ball-type dinuclear Zn(II) and Mg(II) phthalocyanines containing four 4,4′-isopropylidendioxydiphenyl substituents at the peripheral and non-peripheral positions are presented. The structures of the synthesized compounds were characterized using elemental analyses, and UV–Vis, FT-IR, 1H NMR and mass spectroscopies. The ΦF values were 0.14, 0.11, 0.22, 0.15 and ΦT values were 0.84, 0.88, 0.62, 0.74, for 6–9, respectively. The largest triplet yields were observed for the non-peripherally substituted complexes 6 and 7, showing that non-peripheral substitution favors increased population of the triplet state. All complexes showed reasonably long triplet lifetimes with τT 510, 310, 910 and 350 μs in DMSO, respectively.

- Description: The synthesis of ball-type dinuclear Zn(II) phthalocyanine containing four 4,4′-(9H-fluorene-9,9-diyl)diphenol substituents at the non-peripheral position is presented. The structure of the synthesized compound was characterized using elemental analyzes, and UV-vis, FT-IR, 1H NMR and mass spectroscopies. The ΦF value was 0.16 and ΦT value was 0.72. The complex showed reasonably long triplet lifetimes with τT 7210 μs in DMSO. The frequency and temperature dependence of the dielectric properties of ZnPc were also investigated in the frequency range of 40–105 Hz and in the temperature range of 300–440 °K. It has been observed that both dielectric constant ε′ and dielectric loss ε″ decrease with the rise in frequency as they increase with the rise in temperature. The decrease in ε′ with increasing frequency is attributed to the fact that as the frequency increases, the polarizability contribution from orientation sources decreases and finally disappears.

- Description: A major obstacle to the application of nanostructured lipid carriers (NLCs) as carriers for hydrophilic drugs is the limited loading capacity (LC) and encapsulation efficiency (EE) of NLCs for these molecules. The purpose of this research was to design and implement a strategy to enhance the LC and EE of NLCs for the hydrophilic drug, didanosine (DDI). DDI was dispersed in Transcutol® HP and the particle size of DDI in the liquid lipid was reduced gradually using hot high pressure homogenization (HPH). The product obtained thereafter was added to Precirol® ATO 5 and the hot mixture was immediately dried using liquid nitrogen. The dried materials were then ground and passed through a 200 μm sieve and the solid lipid particles were dispersed in a surfactant solution and subsequently used to manufacture DDI-loaded NLCs using cold HPH. The LC and EE of NLCs for DDI manufactured using the new strategy were 3.39 ± 0.63% and 51.58 ± 1.31%, respectively, compared to 0.079 ± 0.001% and 32.45 ± 0.08%, respectively, obtained when DDI-loaded NLCs were produced using conventional hot HPH. The enhanced LC and EE for DDI make NLCs a potential technology for the oral administration of DDI to paediatric patients.

- Description: Captopril (CPT) microparticles were manufactured by solvent evaporation using acetone (dispersion phase) and liquid paraffin (manufacturing phase) with Eudragit® and Methocel® as coat materials. Design of experiments and response surface methodology (RSM) approaches were used to optimize the process. The microparticles were characterized based on the percent of drug released and yield, microcapsule size, entrapment efficiency and Hausner ratio. Differential scanning calorimetry (DSC), Infrared (IR) spectroscopy, scanning electron microscopy (SEM) and in vitro dissolution studies were conducted. The microcapsules were spherical, free-flowing and IR and DSC thermograms revealed that CPT was stable. The percent drug released was investigated with respect to Eudragit® RS and Methocel® K100M, Methocel® K15M concentrations and homogenizing speed. The optimal conditions for microencapsulation were 1.12 g Eudragit® RS, 0.67 g Methocel® K100M and 0.39 g Methocel® K15M at a homogenizing speed of 1643 rpm and 89% CPT was released. The value of RSM-mediated microencapsulation of CPT was elucidated.

The zinc phthalocyanine used contained four phenylthio peripheral substituents (ZnPc(SPh)4). The conjugates formed are represented as ZnPc(SPh)4–AuNP. The absorption spectrum of the ZnPc(SPh)4–AuNP shows a broadening of the phthalocyanine Q-band absorption, probably due to a tight packing of the phthalocyanines on the gold nanoparticle surface. For the attached phthalocyanines, the two fluorescence lifetimes obtained by time-correlated single photon counting (TCSPC) were determined to be both longer and shorter than that of the free Pc. The fluorescence lifetimes were resolved using time resolved fluorescence spectroscopy (TRES).

- Description: This article uses the theoretical and methodological tools of cultural historical activity theory and critical realism to examine three case studies of the introduction and expansion of sustainable agricultural practices in southern Africa. The article addresses relevant issues in the field of agricultural extension, which lacks a theoretical “bridge” between top-down knowledge transfer and bottom-up participatory approaches to learning. Further, the article considers the learning environments necessary for sustainable agriculture. Such environments provided research participants with encounters with “postnormal” scientific practices that recognise and engage plural ways of knowing. Our research explored why farmers learn and practise sustainable agriculture, how they learn and practise it, the contradictions they are facing, and how these contradictions can be overcome in a context of change-oriented learning.

- Description: The massive campaign by Zimbabwe to educate all children was achieved through the education for all policy. When quantity had been achieved more focus was on quality issues. The quality concerns coincided with market-based developments which compelled Zimbabwe to adopt change reforms such as the teacher performance appraisal, one of which focused on quality teaching strategies that would enhance learners’ quality academic achievement. Nevertheless since its inception in 1996 and subsequent implementation in 2000, teachers through their unions have challenged the use of the appraisal which quantifies the teacher’s work, alleging their work cannot be atomized into separate elements to be measured, weighed and then ticked off. The contention highlighted above prompted the need for a research to be carried out which sought to assess: How is the performance appraisal system being implemented in the primary schools? A mixed methods design which is located in the postpositivist paradigm which produced in-depth, detailed, rich data from personal perspectives and experiences that resulted in realistic understanding, interpreted through the social and cultural context of the respondent’s lives. Educators resisted the imported system alleging it was imposed on them without adaptation to local environment. Lack of pilot-testing of the system, lack of proper training and lack of a meaningful reward system perverted the system to a mere ritual that frustrated implementers who found it difficult to use it in their daily work. The study recommends the following: That the educators be incorporated in designing an appraisal system that encompasses the whole teacher’s work package which is geared towards teaching the whole child. That there be a more efficient and sustainable reward system. That the system be interwoven into supervisory mechanisms so that there is no demarcation between the appraisal and daily supervision. , Thesis (PhD) -- Faculty of Education, 2012

- Description: A survey of 50 employees was conducted to identify challenges in the implementation of affirmative action, as well as intervention that have been implemented to escalate its implementation at Nkonkobe Municipality in the Eastern Cape. A closed questionnaire containing 26 items was used to collect date form respondents. The results of the study were analysed and interpreted using descriptive statistics and inferential statistics, that is, Chi square test to measure association between demographic responses to each of the variables. Results indicated that lack of top management commitment to transformation, poor perception about affirmative action by managers about affirmative action, failure to link affirmative action to business strategy and poor representation of relevant stakeholders in the Employment Equity committee, are the fundamental factors that contribute to the sluggish implementation of affirmative action at Nkonkobe Municipality. Findings also revealed that successful implementation of affirmative action also depend on capacitating managers with the skills necessary to implement plans effectively, commitment of top management to making transformation a strategies priority, as well as investment in training and development is necessary to assist beneficiaries to catch up with those employees that have has a better education. , Thesis (MCom) -- Faculty of Management and Commerce, 2012

- Description: Corruption is a virus that has infected all sectors of society not only in South Africa but also in the whole world. The various spheres of government are seemingly not immune against this scourge and its paralysing effect on service delivery. There is no universally acceptable definition of corruption. Its causes are diverse, ranging from administrative to socio-economic, and it manifests itself in various ways. The plethora of anti-corruption legislation and agencies has only served to minimise but not to eradicate corruption from the face of the public institutions. In order to scale up its fight against corruption, the Department of Public Service and Administration developed a strategy aimed at preventing, detecting and investigating corruption in government departments. Subsequently, the Department of Local Government and Traditional Affairs, now called Co-operative Governance and Traditional Affairs, developed a similar strategy for the municipalities. The strategy requires inter alia municipalities to develop minimum anti-corruption capacity which entail developing strategies, systems, policies, procedures and plans to prevent, detect and investigate fraud and corruption. The study sought to establish, in selected municipalities in Joe Gqabi District municipality, whether or not they have established the minimum capacity envisaged in the National anti-corruption strategy. The study found municipalities to have progressed at different stages of establishing and ensuring functioning of those systems, policies and plans but none of them had developed anti-corruption strategy. Consequently, the study recommends inter alia that the establishment of minimum anti-corruption capacity be made one of the national key performance indicators which must be incorporated in the performance agreements of the Senior management of municipalities. , Thesis (MPA) -- Faculty of Management and Commerce, 2012

- Description: This study sought to investigate the practices that the School Management Teams (SMTs) utilize in promoting and monitoring quality teaching and learning in the rural primary schools. The researcher thought it important due to the fact that such actions form part of their central activities. It also aims to explore the kind of difficulties that may be experienced by these formations in rural settings while supporting quality teaching and learning. The main delineations and limitations of this work was that SMTs are supposed to be operational across the spectrum of schools from the first grade to the last one in the high schools. However, due to time constraints and lack of resources, this study was only carried out in three rural primary schools of the king William’s Town district. SMTs are ideally made up of the Principal, Deputy-Principal and HODs (school heads of Department) of these sampled schools who were interviewed. However, in some of the schools under study, the positions of HOD and deputy-principals had already been abolished. The researcher was informed that this was because they had low numbers of learners. In such instances, Senior Teachers were substituted since they are incorporated in the SMTs of those schools. These educators were purposively selected from the foundation, intermediate and senior phases in each primary school. With the research exploring the practices of the SMTs of three rural primary schools, a case study research design was utilized. The research instruments utilized by the researcher to collect data in this case study were Interviews and Document Analysis. The data collected was put into categories and interpreted into common themes. Sources included responses of the participants, school documents, field notes and other relevant documentation such as minutes of the minutes of the SMTs. Constructs, themes and patterns that speak to the strategies used by SMTs in promoting teaching and learning in schools were explored. Briefly, the main findings indicated that the SMTs of the sampled rural primary schools do understand the Departmental policies, but need to be innovative and create space for the practices that they could employ to promote quality teaching and learning. They seem to be working under difficult circumstances. They are grossly over-loaded as full-time administrators and teachers with many learning areas, as well as being responsible for the school nutrition programme. The vacant posts created by retired caretakers added to the overload. There was a concern about the difficulty they were experiencing in the teaching and learning of Mathematics which is nationally regarded as a scarce skill. As an overview of the researcher’s conclusions, it is noted that the SMTs do support the educators to a certain extent. However, there was no documentation that showed how resolutions were made and implemented to validate the nature of support that they give to them. There seemed to be a lack of meaningful parental involvement in the sampled rural primary schools, possibly due to poverty, lack of education and alcohol abuse in the community. Lastly, it seemed to the researcher that there could be uncertainty and uneasiness about the functionality of the senior teachers. Their job descriptions as members of the SMTs remain vaguely defined. In response to the problem statement posed in this study, six major recommendations were made as follows: • Schools, irrespective of their size, ought to have clerks who are able to deal specifically with office administration and external communications. • The teacher-learner ratio as a means of determining the number of educators a school ought to have, should be reviewed as a matter of urgency, if the vital goal of quality teaching and learning is to be realized. • A clear official mandate concerning the job description of senior teachers ought to be established and their positions advertised in that category. This will ensure their equitable distribution as some schools are having them in excess, while others have none. • The department of Education should work with sister departments in government such as Social Development to enforce the law regarding parental negligence. A data basis of negligence parents should be compiled by the concerned departments and reviewed from time to time. Teachers should attend workshops on various policies that govern their roles in the delivery of quality teaching and learning. They need not be conversant with the subject matter only, but also with the relevant policies as a vehicle that facilitates service delivery in education. The introduction of Mathematics support educators who specialized in the learning area should be introduced in each phase of schooling. Such incumbents would rotate from school to school within a circuit, with special reference to rural schools where they would tackle problematic topics as reported by the educators. , Thesis (MEd) -- Faculty of Education, 2012

- Description: The main objective of this study was to critically investigate the mediating role that the use of mobile technology plays in the linkage between customer satisfaction and customer loyalty in a semi-urban environment. The research problem focused on the application of mobile technology in the linkage between customer satisfaction and customer loyalty in the clothing industry in King Williams Town. In accomplishing this objective, this research study hypothesised that mobile technology plays a mediating role in the linkage between customer satisfaction and customer loyalty of customers of clothing retailers in South Africa. Multiple regression was conducted to test for the first hypothesis. The first secondary objective aimed at establishing if there is disconfirmation between customer expectations and the performance of clothing retail outlets in King Williams Town. In exploring this objective, it was hypothesised that there is negative disconfirmation between customer expectations and performance. A paired sample test was conducted to test for this hypothesis. In addition, the influence of service quality and customer satisfaction on customer loyalty was explored. To accomplish these, it was hypothesised that both service quality and customer satisfaction have an influence on customer loyalty. Pearson’s Correlation and the Chi-Square Test were applied to test the influence of service quality and Customer satisfaction on Customer loyalty. Data was analysed using the Statistical Package for Social Sciences (SPSS) statistical software. Regression analysis, chi-square tests, Paired sample tests and correlation reports were used to analyse data inferentially. Reliability and validity of the research was also tested using Cronchbach’s alpha test. The results show that mobile phones have become a basic necessity for customers and that mobile technology plays a mediating role in the linkage between customer satisfaction and customer loyalty; however, the mediation is partial. The results also show that there is positive disconfirmation between customer expectations and retailer performance; that both service quality and customer satisfaction have a positive correlation with customer loyalty and that mobile technology enhances customer loyalty. Finally, the results show that the total service experience of customers is favourable because the five components of service quality were rendered at a high level of service quality. The study offers several managerial recommendations. Firstly, retail managers should make strategic investments in mobile technology and use this technology to the full to reap the benefits of technologically advanced mobile communication. Secondly, managers should be creative in their use of this mobile technology to enhance customer satisfaction and, hence, customer loyalty. Thirdly, managers should prioritise the improvement of all five components of service quality in order to enhance customer loyalty. Finally, managers should provide a customer-centred service experience that exceeds customer expectations for service quality and mobile communication, one that maximises customer satisfaction and loyalty. The implementation of these recommendations could result in clothing retailers providing a customer-focused service experience in all five aspects of service quality. To successfully implement these recommendations, clothing retailers should: ensure that expectations created, could be accomplished or exceeded to build and enhance customer satisfaction; create expectations that are realistic to avoid negative disconfirmation and hence customer dissatisfaction; implement innovative and creative mobile communication strategies to build and enhance customer loyalty; and finally, improve loyalty programmes to enlarge the customer base. , Thesis (MA) -- Faculty of Management and Commerce, 2012
