- Description: This study investigates parental involvement in school governance in selected high schools in Zwelitsha, King Williams Town District in the Eastern Cape Province. The research study was conducted in three high schools in Zwelitsha Township. These schools are Nompendulo Senior Secondary, Thembalabantu High School and Xolani Senior Secondary School. Questionnaires were designed and distributed to the principals, educators and parents whose children are learners in these schools. The interview questions were designed and distributed to parents whose children are learners in these selected schools, educators and school principals and members of the school governing body from each school. Respondents were asked about the levels of parental involvement in their schools, parents’ awareness of school governance and the relationship between schools and communities. However, the objectives of the study were to: Assess parental involvement in school governance in selected high schools in Zwelitsha, King Williams Town District in the Province of the Eastern Cape; To determine the nature and extent of parental participation in school academic activities; To examine the role of parents in the school governing body; To determine measures that can be taken to encourage the participation of parents in school governance These objectives have been achieved by providing empirical evidences which shows that the levels of parental involvement in the previously disadvantaged high schools are very low. This is related to the parents’ level of education. Parents who are literate are more involved than those are illiterate. This research also reveals that high v. levels of working parents contributes to the low levels of parental involvement in school governance. Most parents in this area know nothing about school governance and those that are aware are not keen to be involved. The class structure of the society has an influence in the participation of parents in school governance. Parents’ meetings that are held on Sunday afternoon are a challenge to parents that come from the villages outside Zwelitsha because of the scarcity of transport on this day. and these situations discourage them from being actively involved in their children’s education. The study provides the factors that cause non-involvement of parents in school governance. Subsequently, the following strategies for participation of parents in school governance were given: Capacitating of parents Establishment of teacher-parent collegiality Recognition of cultural capital Establishment of parent organisations Utilisation of non-governmental organisations Establishment of centres of learning. This study also indicates the following strategies that may assist to enhance the parental involvement in school governance: Parents engagement and empowerment Co-operation between schools and parents Collaboration with other community, private and other public institutions Invitation of complaints and welcoming of criticism. In conclusion, the findings provide clear indication that the participation of parents in school governance is low. Recommendations that could assist the schools to encourage and to enhance parents to participate in school governance are given.

- Description: South Africa’s freshwater quality and quantity is declining and consequently impacting on the ecological health of these ecosystems, due to increased agricultural, urban and industrial developments. The River Health Programme (RHP) was designed for monitoring and assessing the ecological health of freshwater ecosystems in South Africa, in order to effectively manage these aquatic resources. The RHP utilises biological indicators such as in-stream biota as a structured and sensitive tool for assessing ecosystem health. Although the RHP has been widely implemented across South Africa, no attempts have been made to explore microbial ecology as a tool that could be included as one of the RHP indices. This study used selected microbial responses and water physico-chemical parameters to assess the current water quality status of the Buffalo River. This study showed that water quality impairments compounded in the urban regions of King William’s Town and Zwelitsha and also downstream of the Bridle Drift Dam. The results also showed that the lower and the upper catchments of the Buffalo River were not significantly different in terms of water physico-chemistry and microbiology, as indicated by low stress levels of an NMDS plot. Though similarities were recorded between impacted and reference sites, the results strongly showed that known impacted sites recorded the poorest water physico-chemistry, including the Yellowwoods River. However, the Laing Dam provided a buffer effect on contributions of the Yellowwoods River into the Buffalo River. Multivariate analysis showed that microbial cell counts were not influenced by water physico-chemical changes, whilst microbial activity from the water and biofilm habitats showed significant correlation levels to water physico-chemical changes. This study demonstrated that further investigations towards exploitation of microbial activity responses to water physico-chemical quality changes should be channelled towards the development of microbiological assessment index for inclusion in the RHP.

- Description: The laser surface hardening process will enhance the hardness profile of automotive components and ensure better process control and predictability of quality as compared to the conventional hardening processes. A 2KW Nd-YAG laser system was used to harden the surface of alloy steel with various process parameters (laser power, focal spot diameter and beam velocity). The results (microhardness, microstructure change and residual stress distribution) were measured and analyzed with Vickers microhardness tester, optical/electron microscope and hole-drilling residual stress equipment. Statistical analyses of the experimental data were used for explaining the relationships between process parameters, microhardness and microstructure. General thermal hardening was applied in the research to show the influence of heating temperature and cooling method on microstructure and mechanical properties. Also, the results were compared with laser surface hardening process from microhardness, microstructure and residual stress to show the advantage of laser surface hardening. Through analysis of the results of the laser surface hardening experiments, a suitable laser power density and interaction time for optimum hardening was obtained. The presented laser surface hardening process can also be applied to other alloy steel surface hardening process.

- Description: Metallophthalocyanines confined on the surface of electrodes are active catalysts for a large variety of electrochemical reactions and electrode surfaces modified by these complexes can be obtained by simple adsorption on graphite and carbon. However, more stable electrodes can be achieved by coating their surfaces with electropolymerized layers of the complexes, that show similar activity than their monomer counterparts. In all cases, fundamental studies carried out with adsorbed layers of these complexes have shown that the redox potential is a very good reactivity index for predicting the catalytic activity of the complexes. Volcano-shaped correlations have been found between the electrocatalytic activity (as log I at constant E) versus the Co(II)/(I) formal potential (E°′) of Co-macrocyclics for the oxidation of several thiols, hydrazine and glucose. For the electroreduction of O2 only linear correlations between the electrocatalytic activity versus the M(III)/M(II) formal potential have been found using Cr, Mn, Fe and Co phthalocyanines but it is likely that these correlations are “incomplete volcano” correlations. The volcano correlations strongly suggest that E°′, the formal potential of the complex needs to be in a rather narrow potential window for achieving maximum activity, probably corresponding to surface coverages of an M-molecule adduct equal to 0.5 and to standard free energies of adsorption of the reacting molecule on the complex active site equal to zero. These results indicate that the catalytic activity of metallophthalocyanines for the oxidation of several molecules can be “tuned” by manipulating the E°′ formal potential, using proper groups on the macrocyclic ligand. This review emphasizes once more that metallophthalocyanines are extremely versatile materials with many applications in electrocatalysis, electroanalysis, just to mention a few, and they provide very good models for testing their catalytic activity for several reactions. Even though the earlier applications of these complexes were focused on providing active materials for electroreduction of O2, for making active cathodes for fuel cells, the main trend in the literature nowadays is to use these complexes for making active electrodes for electrochemical sensors. , Original publication is available at http://dx.doi.org/10.1016/j.ccr.2010.05.001

- Description: The reaction of the potentially tridentate Schiff-base chelate Hhaep [Haep = N’-(1- (2-hydroxyphenyl)ethylidene)benzohydrazide] with [ReCl3(benzil)(PPh3)] and trans-[ReOCl3(PPh3)2] produced the neutral oxorhenium(V) complexes cis- [ReOCl2(mep)] [Hmep = 2-(1-iminoethyl)phenol] and cis-[ReOCI2(meb)(PPh3)] [Hmeb = N’-(propan-2-ylidene)benzohydrazide] in ethanol and acetone respectively. In both reactions the Hhaep molecule cleaves to give different coordinated bidentate NO-donor chelates coordinated to the rhenium(V) centers. The X-ray studies reveal that mep is present as a bidentate, monoanionic Schiffbase coordinating through the neutral imino nitrogen and the deprotonated phenolate oxygen in cis-[ReOCl2(mep)]. The bond distances and angles in cis- [ReOCI2(meb)(PPh3)] confirm that meb coordinates to the metal in the enolate form. The distorted octahedral complex fac-[ReCl3(dpa)(PPh3)] was prepared by the reaction of trans-[ReCl3(MeCN)(PPh3)2] with a twofold molar excess of dpa in acetonitrile under a nitrogen atmosphere. The compound dpa.HCl.2H2O was obtained as a by-product in the reaction of dpa with trans-[ReCI3(MeCN)(PPh3)2] in acetonitrile. The reaction of trans-[ReCl3(MeCN)(PPh3)2] with a twofold molar excess of 6- amino-3-methyl-1-phenyl-4-azahept-2-ene-1-one (Hamp) in acetonitrile led to the isolation of cis-[ReCl2(bat)(PPh3)2]. On complexation to the metal center Hamp decomposed to give the coordinated benzoylacetone (bat). Bat is present as a monoanionic bidentate chelate. The complexes [ReVOCI(had)] and [ReIVCl(had)(PPh3)](ReO4) were prepared from the reaction of trans-[ReCl3(MeCN)(PPh3)2] with N,N-bis((2-hydroxybenzyl)-2- aminoethyl)dimethylamine (H2had) in ethanol under various reaction conditions. The treatment of [ReCl3(benzil)(PPh3)] with 2-[((2- pyridinylmethyl)amino)methyl]phenol (Hham) in a 2:1 molar ratio in acetonitrile led to the isolation of the hydrogen-bonded dimer [ReOCl2(ham)]2. The distorted octahedral complex [ReOCl(hap)] [H2hap = N,N-bis(2- hydroxybenzyl)aminomethylpyridine] was prepared from the reaction of trans- [ReCl3(MeCN)(PPh3)2] with a twofold molar excess of H2hap in acetonitrile. The X-ray crystal structure analysis shows that the chloride is coordinated trans to the tripodal tertiary amino nitrogen, with a phenolate oxygen trans to the oxo oxygen.

The representation of women's reproductive rights in the American feminist blogosphere: an analysis of the debate around women's reproductive rights and abortion legislation in response to the reformation of the United States health care system in 2009/10

- Description: This study investigates the representation of women's reproductive rights in the feminist blogopshere during 2009/10 United States health care reform. Focusing on two purposively selected feminist blogsites - Feministing and Jezebel- it critically examines the discursive and rhetorical strategies employed by feminist bloggers to contest the erosion of women's reproductive rights as proposed in health care reform legislation. While the reformation of the U.S. health care system was a lengthy process, my analysis is confined to feminist blog posts published in November 2009, December 2009 and March 2010. These three months have been designated as they are roughly representative of three pivotal stages in health care reform: the drafting of the House of Representatives health care reform bill and Stupak Amendment in November 2009, the creation of the Senate health care bill inclusive of the Nelson compromise in December 2009, and the passage of the finalised health care reform bill, the Patient Protection and Affordable Care Act and supplementary executive order, in March 2010. This study is informed by feminist poststructuralist theory and Foucault's conceptions of discourse and power - an appropriate framework for identifying and analysing the unequal power relations that exist between men and women in patriarchal societies. Foucault conceives of discourse as both socially constituted and constitutive and contends that through the constitution of knowledge, discourses designate acceptable ways of talking, writing, and behaving, while simultaneously restricting and prohibiting alternatives, thereby granting power and authority to specific discourses. However, Foucault also stresses the multi-directionality of power and asserts that though hegemonic discourses are privileged over others, power lays in discursive practice at all social sites; hence the socially and politically transformative power of contesting discourses. Critical discourse analysis is informed by this critical theory of language and regards the use of language as a form of social practice located within its specific historical context. Therefore, it is through engaging in the struggle over meaning and producing different 'truths' through the reappropriation of language that the possibility of social change exists. Employing narrative, linguistic and rhetorical analysis, this study identifies the discursive strategies and tactics utilised by feminist bloggers to combat and contest anti-choice health care legislation. The study further seeks to determine how arguments supportive of women's reproductive rights are framed and how feminist discourses are privileged while patriarchal discourse is contested. Drawing on public sphere theory, I argue that the feminist blogosphere constitutes a counter-public which facili tates the articulation and circulation of marginalised and counter-discourses. I conclude this study by examining the feminist blogopshere's role in promoting political change and transformation through alternative representations of women and their reproductive rights.

- Description: The honeybees Apis cerana and Apis mellifera are derived from the same ancestral base about two million years ago. With speciation and evolution, they have acquired many advanced living skills in common, but have also evolved very different living strategies due to different distributions. This thesis is an intensive study of the biology of the mixed-species colonies of these species, the aims of which were to investigate their behavioural relationships and uncover the evolutionary conserved features of their behaviours subsequent to speciation. The results show that the two species can form a stable society to perform normal tasks. First, workers of both species in the mixed-colonies could form the typical retinue behaviour to hetero-species queens, thus indicating that queen pheromones could be spread to and by both species. Secondly, both species did not show significantly different ovarian activation under hetero-species queens, suggesting that the queen pheromones more likely play a role of "honest signal" rather than a "repression" substance in the honeybee colonies. Thirdly, both species could mutually decode each other‘s waggle dances, with unexpectedly low misunderstanding; revealing that the dance language in a dark environment is quite adaptive for cavity-nesting honeybees. Fourthly, workers of both species could cooperate with each other in comb construction, although the combs they built contain many irregular cells. Interestingly, A. cerana workers could be stimulated by A. mellifera workers to perform this task, thus confirming self-organization theory in the colony. Fifthly, A. mellifera workers behaved more "defectively" in thermoregulation, but perhaps because A. cerana workers are more sensitive to changes in hive temperature. Given these differences in strategy, A. mellifera workers‘ performance might in fact reduce conflicts. Lastly, when faced with threats of predatory wasps, both species engaged in aggressive defence. Although they did not learn from each other‘s responses, species-specific strategies were adopted by each of them so that the defence of the mixed-colonies is very effective. I conclude that the two species can adapt to each other‘s efforts and task allocation is reasonably organized allowing mixed-species colonies to reach stability. These results suggest that all of the social behaviours discussed here were highly conserved following speciation. This thesis could provide some clues for the study of honeybee evolution from open-nesting to the transition of cavity-nesting.

- Description: The study was conducted at the University of Fort Hare farm to assess the effect of dietary supplementation on physico-chemical and consumer sensory characteristics of chevon from South African indigenous goat genotypes. Forty-eight 6-month-old Xhosa lop-eared (XLE), Nguni (NGN), Xhosa-Boer cross (XBC) and Boer (BOR) castrated goats with a body weight range from 20 to 25 kg were used in this study. Half of the goats in each genotype were supplemented with 200g/head/day of sunflower cake. The other half of goats in each genotype was not supplemented. The goats were slaughtered at day 90 to determine slaughter weight (SLW), cold dress mass (CDM), meat colour, cooking loss, meat pH and Warner-Bratzler (WB) shear force values. Furthermore, a consumer sensory evaluation of cooked or fried chevon from supplemented and non-supplemented goats was conducted with consumers of different ages, tribes and gender. The XLE and NGN goats had higher pH24 (P < 0.05) than BOR and XBC goats. Supplemented BOR goats had higher L* values than their non-supplemented counterparts (P < 0.05). The other meat quality attributes in XLE and NGN were comparable to those in meat from the Boer goat. Female respondents gave higher (P < 0.05) sensory scores than male respondents for both cooked and fried meat on aroma intensity. Shona consumers gave higher (P < 0.05) aroma intensity scores than the Xhosa and the Zulu consumers for both cooked and fried meat. In the non-supplemented goats, fried meat for all genotypes was superior (P < 0.05) to the cooked meat for initial impression of juiciness. Age and gender of respondents and thermal iv treatment influenced initial impression of juiciness scores (P < 0.05). The quality of chevon from XLE and NGN was comparable to that of the Boer goat, and dietary supplementation improved most meat quality attributes. Chevon from the supplemented goats had higher consumer sensory scores than chevon from the non-supplemented goats. Keywords: supplementation, meat colour, ultimate pH, consumer sensory evaluation, Xhosa lop eared, Nguni, Boer goats.

- Description: This research study aims to investigate the South African Land Reform process from a conflict resolution perspective. According to Burton’s basic human needs theory deep-rooted social conflict will occur wherever social institutions neglect universal basic human needs. Excess to land and land tenure are considered basic human needs because they provide landowners with food, shelter and security. In absence of an extensive welfare state, land ownership fulfils the role of a social safety network, particularly in African countries. Consequently, an equal distribution of land is needed in order to enable the majority of South Africans to fulfil their basic human needs. The instrument chosen for correcting the inequalities in land distribution are the three components of the South African land reform programme namely tenure reform, restitution and redistribution. The South African Land Reform Programme was largely influenced by the World Bank’s ‘Willing-Seller Willing- Buyer’ or ‘Negotiated Land Reform Approach’. Nevertheless, the South African model differs from the original concept by the World Bank in some aspects. The outcome of the Land Reform Process is analysed and evaluated by the on-going evaluation approach. All sources used in this research are open to the public and published either on official websites or in hard cover version in reports and articles. The results of this investigation indicate that the target of redistributing 30% of white-owned agricultural land by the year 2014 is not going to be accomplished. Nevertheless, the settlement of claims can be considered a success story although most of the claims were settled by means of cash compensation instead of actual land transfer. Furthermore, a change in the land acquisition policy from a demand-led approach based on the negotiated land reform principle towards a more static, state-led, top-down approach has been identified as well as shortcomings in the post-settlement support of new landowners. To put it briefly, the land reform process in toto is about to fail and a chance of reducing the enormous conflict potential given away. Furthermore, the conflict potential will increase due to the failures in providing the poor and rural masses with access to land.

Exploring work by Mongane Serote, B.W. Vilakazi, Demetrius Segooa, Phedi Tlhobolo, Thami Mseleku, Jeremy Cronin, Alan Lennox-Short, Anthony Farmer, Freedom T.V. Nyamubaya, Abduraghiem Johnstone and Mondli Gwala, the argument shows some of the ways in which the technological character of trains and railways is made to carry a message of political insurrection and revolution. The author shows that the political potential of the railway metaphor builds on the general response to railways evident in poems indebted to traditional African praise poetry. The piece also demonstrates that political contention within different strands of the southern African liberation movement could also find expression using the railway metaphor.

The remark came in the course of a debate concerning the cost of the SKA project, the massively expensive square kilometer array telescope for which South Africa is bidding against Australia, viewed in relation to the country’s huge list of social backlogs: Big science versus food and decent housing; a false opposition, or a grim choice? You can imagine the debate. The nugget that stayed with me was the tangential comment that ordinary people are always interested in the cosmos. If so, is this true merely because human cultures traditionally incorporate such an interest, or because humans themselves actually need a relation to the cosmos? What might this need be?

- Description: preprint , One of the teasing characteristics of novels soused in literariness, like J.M. Coetzee’s, is their tendency to leak, to bleed, into vast inchoate terrains of intertextuality.The reader is constantly challenged to measure and assess their implications within or against the frail containing form of the story, much as Russian formalism taught us to keep sujet and fable in perpetual dialogue. However, it has become apparent that in the dense thickets of commentary occasioned by Coetzee’s most controversial novel, Disgrace (1999), insufficient attention has been paid to the intertextual implications of David Lurie’s learning, his scholarly preoccupations. Unless the reader attempts this kind of exploration, two of the most vexed issues freighting the novel’s central fabulation: Lucy’s curiously stoical, impassive response to her rape, together with her decision to stay on in South Africa; and David Lurie’s sudden, seemingly inexplicable care for the doomed dogs, from their last moments at the animal shelter until he lovingly consigns their corpses to the incinerator, must remain opaque. In particular, the final words of the novel, “Yes, I am giving him up” (220), uttered in relation to the immanent “Lösung” of the little dog Bev Shaw calls Driepoot, will tend to taunt the reader, rather than illuminate.

- Description: The aim of this study was to assess the effects of a twelve-week hydrotherapy group exercise programme on selected health-related fitness variables in older women with type II diabetes mellitus. This study included the testing of blood glucose levels, blood anthropometrical profile, body mass, height, body mass index, waist circumference, waist-to-hip ratio, upper body flexibility, lower body flexibility, grip strength, upper body and lower body muscular strength and endurance as well as aerobic endurance. Descriptive and inferential statistical techniques were used for this study utilising a quasiexperimental research design. A comparison group pre-test and post-test experimental design was employed at the Nelson Mandela Metropolitan University Biokinetics and Sports Science Unit. Approximately 16 senior female participants took part in the study. Participants were identified through convenience sampling and snowball sampling, of which, all the participants were clinically diagnosed with type II diabetes mellitus and had completed the study. The hydrotherapy participants (experimental group), took part in water-based (hydrotherapy) exercises three times a week for a period of twelve weeks. The hydrotherapy exercises began with a light half-hour workout per session and were progressively increased in intensity, duration, and number of the exercises performed. The participants not participating in the hydrotherapy exercises (control group) were instructed to remain sedentary throughout the duration of the intervention period. The dependant variables were gathered as raw data and analysed using descriptive statistics to form the means, standard deviations, medians, minimum and maximum values. Post hoc analysis was performed to determine whether differences existed between the experimental group and control group. Cohen’s D test was used to determine pre- and post-test differences for both groups to determine practical significance. An analysis of the results revealed significant improvements in some of the selected health and physical fitness parameters such as, upper body and lower body flexibility, upper and lower body muscular strength and endurance, as well as aerobic endurance. iii The aim and objectives of the study in exploring the effect of hydrotherapy as an intervention strategy to promote health and physical fitness in persons with type II diabetes mellitus were supported by the data collected in the pre-test and post-test analyses of the variables.

Two methods, fluorochrome marking and edge analysis of otoliths were used. For fluorochrome marking, specimens of both species were injected with 60 mg/kg fish mass oxytetracycline hydrochloride (OTC) and released into large earthen ponds under ambient conditions adjacent to Lake Gariep. Twenty-three L. aeneus and one L. capensis were recaptured 10–14 months later. Edge analysis was based on the optical interpretation of L. aeneus (n = 342) and L. capensis (n = 512) otolith margins collected between November 2006 and May 2008 from Lake Gariep. The frequency distribution of opaque margins over time was fitted using a binomial periodic regression. The estimated cycle length was not significantly different from a hypothesized 12 months for both species. The number of growth zones distal to the OTC mark was consistent with findings from the edge analysis, providing evidence that growth zones in astericus otoliths of both species can be interpreted as annuli.

- Description: This paper describes the assumptions and results of a study to assess whether cultivation of medicinal plants can serve as a tool for combined biodiversity conservation and poverty alleviation. The study was carried out in the Amatola region of Eastern Cape, South Africa, where sustained beliefs in medicinal plant use, also under non-traditional conditions, has resulted in an increase in commercial demands. It was based on the assumption of poverty alleviation not only referring to an increase in income and labour, but also an increase in social capital and human dignity. The study assessed the local perceptions of the use and cultivation of medicinal plants and the need for conservation of these plants, as well as the features of already ongoing cultivation practices and options for increased cultivation. It consisted of participatory assessments in three villages involving around 250 persons and participatory trials with 14 rural women selling medicinal plants on urban markets. The study indicated that the growing demand for medicinal plants is related to the great cultural significance attached to medicinal plants.

- Description: It has been twenty years since F W De Klerk unbanned the African National Congress. This momentous occasion changed overnight the business landscape in South Africa and the way business were done for many decades. Before and after this crucial moment in South African history, leaders played a significant role in bringing change about as well as managing it. Whether hierarchical or non-hierarchical, leadership manifests itself through all spheres of civilisation. Within any collective, formal as well as informal leadership are always at work and within the environment there always seems to be an individual that appears to hold equal or more influence and sway over the collective. This research investigates the characteristics and role of this individual, the informal leader. In addition, against the melting pot of the diversity of culture, social structures, economics, and demographics in South Africa, the influence of culture on how leadership is being perceived and experienced is also researched. The research is grounded in a post-positivists approach and conducted within a constructivist-interpretative paradigm. A qualitative approach is followed with personal interviews as the method to collect the data from respondents. The interview protocol consists of a combination of questions containing questions of both a quantitative and qualitative nature. Questions of a qualitative nature were open-ended and of an in-depth nature. The research is two pronged. The focus of the research is an Original Equipment Manufacturer (OEM) in the South African Motor Industry and for the primary goal of the research data was collected from employees within work groups of the OEM. The primary research goal investigates the role and characteristics of informal leaders in work groups as seen and experienced by their fellow employees and if there is any congruence with that of the role and characteristics of formal leaders. The study found no fundamental differences between the characteristics and role of formal and informal leaders. The characteristics and role of leaders between different cultures also appear to be the same. For the secondary research goal – determining whether the role and characteristics of informal leaders in work groups could be underpinned in the principles of Ubuntu and if consideration should be given to any cultural differences between leaders and followers by organisational hierarchies – the literature was reviewed in order to reach a conclusion with regards this goal. The literature indicates that culture does affect leadership, especially on how the leadership is executed and experienced in a multicultural society and if ignored, will have a detrimental effect on effective leadership. In order to strive towards achieving maximum productivity, it is imperative that management in South African organisations be aware of the changed dynamic within their organisations as well as on the global stage. The research therefore ends with the practical implications of informal leaders for organisations in South Africa. It is recommended that the importance and contribution of informal leaders within work groups in a multi-culture organisation needs not only to be considered as an element of group leadership, but should be accommodated by the organisation. It is also recommended that organisations recognise the cultural differences between leaders and followers in organisations and the possible consequences if ignored. If the competitive pressures and requirements of globalisation are ignored against the background of Afrocentric expectations and motivational imperatives of the South African workforce, it will result in an ineffective workforce, which will in due course render these organisations uncompetitive and non-sustainable locally and globally.

- Description: The South African motor industry plays a pivotal role in the economy of South Africa and is a leading indicator in economic change. In general, satisfaction of customer service in the motor industry is steadily improving. However, as research has shown, there is still room for improvement within the industry. Knowing what customers expect is a critical step in delivering good quality service to ensure customer retention in the long-term (Zeithaml, Parasuraman & Berry 1990:62-63). Having a good understanding of the value of forming long-term relationships with customers and their evaluation of the quality of the service provided, cannot be underestimated, as failure to actually ask customers what they think of the service could be detrimental in the long-term. Vehicle manufacturers conduct ongoing research to monitor customer perceptions of the quality of the service provided by their vehicle retailers. The information generated from the research findings can be used by manufacturers to improve levels of service where this appears to be lacking, and deal promptly with any customer complaints. Against this background, how vehicle owners judge the quality of the service provided by a franchised vehicle retailer for a repair and maintenance service, will be crucial to understanding how customers form perceptions of service related firms specifically, and in general, even an entire industry. The primary objective of this study is to assess customer perceptions of service quality with a franchised vehicle retailer following a routine repair and maintenance service. The sample consisted of 3 859 respondents who had their vehicles serviced at a GM South Africa franchised vehicle retailer over a one month period. The empirical results of the study revealed that GM South Africa show general positive results in terms of customer service satisfaction, however, there are some areas where additional attention is required.

- Description: The main purpose of this dissertation is to investigate if a teaching method called Focus on Form (FonF) in an English as a Second Language (ESL) class is effective in the acquisition of two grammatical forms namely articles ("a", "an" and "the") and a selection of pronouns. In order to test this hypothesis, quantitative research was performed. The analysis of a series of tests was done quantitatively to prove the hypothesis. The dissertation includes a theory section on Social Capital (SC) and discusses why it might play an important part in South Africa and in offering some help to the communities to enable them to help in the education of their children within South Africa. This dissertation is divided into five chapters. The first chapter introduces the problem and explains how South African education, historically, had devastating effects in the past and continues having a far reaching effect on today‟s learners. It discusses why this dissertation focuses on English and highlights how extensively English has spread throughout the world. It contains an explanation of the value of being competent in the English language. The chapter continues with a depiction of the poor pass rates of the end of year high school examinations, The National Senior Certificate (NSC). It explains the significance of the research, the purpose of the study, its theoretical framework and finally what this study proposes. Chapter two is a literature review of the available literature discussing second language acquisition (SLA) and the difference between English as a Foreign Language (EFL) and English as a Second Language (ESL). The chapter continues with a detailed description of how English was taught historically with an explanation of the approach being used in this study. Chapter two continues with details of the historical "Bantu Education Act No 47 of 1953" and the racist policies of the government of the time with an exploration of the effect these policies had on the education of learners. It also specifies the grammatical forms being used in this study. A summary of Black South African English (BSAE) is included accompanied by a description of language transfer. The chapter contains a section on SC, with an explanation of how this term came about historically and what it means. The chapter includes social problems that South Africa is facing today and how these problems tie in with diminished SC. It explains the importance of SC in Education. The chapter concludes with an explanation of how SC can be utilized in communities and why it is important in a democratic country. Chapter three explains the methodology used in this study as that of positivism and that this study in one sense is purely an empirical study and the reasons behind the choice of methodology. It also explains how a section of this study is pragmatic. Although the testing and analysis is purely statistical, the lessons that took place in the classroom, the interpersonal communication combined with the interaction between the learners and the researcher was not quantitative in nature. This interaction had no outright bearing on the results, but allowed the researcher the opportunity to observe and take notes on the experiences of the learners and the researcher in the classroom. These observations included incidents within the lessons and external problems the learners face which are linked to social issues within the literature. The chapter also contains an explanation of the testing instruments used in this study and how they were developed along with the ethical considerations of the study. Chapter four details the statistical results of this study. It also contains the write up of the field notes of the researcher who took note of incidents that happened within the classes. There are some examples of family and personal problems related to the learners and details the environment of the school. Some of these issues tie in with the theory included; illustrating the ideas and concerns associated with SC and demonstrates how these social problems are truly part of each learner‟s life in a township school. Chapter five offers recommendations to English teachers, the Department of Education (DoE) and to future researchers based on the results of Chapter four. It contains a discussion on how the community can increase SC within their own areas and within the schools. This study argues that the Education system is in dire need of help as evidenced by the dismal exam results. It also argues that South Africa has a variety of social problems that are contributing to the overall failure and dropout rate in schools. It offers some general suggestions on how the community can work together to build systems within the community, to help themselves and their children to become educated, productive members of society. The only way for the children of South Africa to succeed is with a good education as their starting point.
