  • Description: This study examines the extent to which the Siyazondla food programme, which is a woman based project, empowers women with agricultural skills and knowledge to alleviate poverty and improve their quality of lives in Ducats North area in East London. The investigation is based on the argument that when a woman is empowered, poverty will be reduced and the quality of life will improve. Through the use of qualitative research methodology, all women who are the main beneficiaries of the Siyazondla programme in Ducats North village were interviewed. Findings seem to indicate that although women in the project manage to produce good crops to feed their families, they are still not sufficiently empowered with skills and education to improve their quality of lives. This was found to be exacerbated by the fact that the officials assigned for the programme are to a greater extent inefficient and lack relevant knowledge to support beneficiaries. Most importantly, it was revealed that there is lack of monitoring and evaluation of the programme by government and this was considered to be the major constraint to successful implementation of the programme and in ensuring that poverty is alleviated in the area. It is on the basis of these findings that the study recommends that in order to yield positive results and ensure that women in the programme are empowered, there is a need to change the deeply embedded patriarchal perceptions and discriminatory practices and attitudes that seem to undervalue women‟s work. This will require greater awareness of women‟s contribution to agriculture, and the recognition of the role played by women in food security and poverty alleviation, coupled with a strong commitment from the government to empower rural women in agriculture.

  • Description: Despite the demand for ICT skills, businesses are experiencing an ICT skills shortage. Constantly changing ICT technologies require business leaders to find qualified ICT professionals to implement new business strategies and business processes. The Information and Communications Technology (ICT) sector is experiencing a continued skills shortage and various initiatives have been launched to address the problem. Businesses continually struggle to find qualified and suitably skilled ICT personnel. As a result businesses have had to outsource their ICT requirements off-shore to obtain the required ICT skills and maintain their competitive advantage. In a country desperate for job creation, entrepreneurial inclination and start up of new businesses may play a pivotal role in the economic development and well being of individuals able to capitalise on the availability of ICT opportunities. Entrepreneurship is a critical factor in promoting innovation, creating employment opportunities and generating social and economic wealth in a country's economy. Sectors such as Information and Communication Technologies can be seen as archetypal entrepreneurial industries and can consequently play a key role in economic development. In the research that follows the author identifies an ICT skills shortage in South Africa. This is followed by an exploratory study that investigates the influence of psychological traits and socio-cultural variables on the entrepreneurial intent of selected ICT SMME’s in the Nelson Mandela Metropolitan Area. The findings revealed that both psychological traits together with socio-cultural variables influence an individual’s intention to start up a business. The predominant psychological trait discovered during the research was perseverance. Family environmental issues were the dominant socio-cultural variable influencing entrepreneurial intention amongst the case study subjects.

  • Description: This study investigates the existence of the value premium in South Africa’s equity market, and tests extrapolation as a possible explanation for it. The value premium refers to the widely reported superior performance of share price returns of value companies compared to growth companies. The value premium represents an anomaly in mainstream rational finance theory, because it should not persist, unless it could be explained as the result of some composite form of risk. What is highly vexing is the fact that the value premium not only persists in most financial markets over a long period, but that the risk explanation cannot be upheld convincingly. This contributed to the rise of behavioral finance, an approach which introduces psychological factors to provide new explanations for financial phenomena. The behavioral finance explanation for the value premium observation is extrapolation (the tendency to project recent experience too far into the future). This study applies propositions and methods from behavioral finance to investigate the South African equity market. The existence of a value premium in South Africa was investigated by using twenty-nine years’ worth of accounting and share price data. The study employed one- and two-dimensional tests for portfolio formation, and tracked share price returns for up to five years after portfolio formation. The results indicated that a statistically and economically significant value premium existed in South Africa for the period between 1972 and 2001. Extrapolation as a potential explanation for the value premium observation was investigated by applying internationally used methods. Extrapolation was found to provide a robust explanation for the South African value premium.

  • Description: The experiences of pregnant teenagers as related to ante-natal care were researched. The primary objective of the study was to explore and describe the experiences pregnant teenagers had of their ante-natal care. The researcher recommended measures based on the findings of the study to midwives to encourage ante-natal care clinic attendance amongst pregnant teenagers. The recommendations were such that even nurses at Primary Health Care clinics could utilise them as they also come into contact with pregnant teenagers. An increasing number of pregnant teenagers in the Nelson Mandela Metropolitan Municipality area are admitted to referral hospitals with complications during pregnancy and labour. Some of these teenagers are un-booked or had only a few ante-natal clinic visits. The researcher therefore wanted to obtain first hand information related to the reluctance of pregnant teenagers to attend ante-natal care clinics. Attendance at ante-natal care clinics plays an important part in enabling the staff to screen pregnant mothers for health problems and so limit complications. Hence the concern and need to develop measures to motivate pregnant teenagers to attend ante-natal clinics.

  • Description: The World Health Organisation (WHO) declared tuberculosis (TB) a global emergency, and this infectious disease remains a health threat by being the leading cause of death amongst adults (Naidoo, Dick & Cooper, 2008:55). In 2005, South Africa was ranked seventh in the world for having the highest TB rate and the lowest TB success rate in the world. As a professional nurse involved in the tuberculosis programme at a clinic in the Nelson Mandela Bay Municipality at local government level for approximately three years, the researcher observed that the morale of professional nurses who provide TB services appeared to be low. They also appeared to be frustrated because they feel that they are not winning the battle with regard to the TB epidemic in their communities irrespective of their efforts to try and curb the spread of the disease. The extent of the workload per person also appeared to add to the low morale and frustration of the professional nurses rendering TB health services because they feel that they are unable to manage everything. The objectives of the study were therefore to explore and describe how professional nurses experienced the management of health services being rendered to TB patients in Sub district B of the Nelson Mandela Bay Municipality (NMBM) in order to make recommendations that could be used by the district manager to address the research findings. The research study was based on a qualitative, explorative, descriptive and contextual research design. The research population consisted of all professional nurses who worked in the TB services of Sub district B. Non-probability, purposive sampling was used to select the participants for the study. Seven in-depth and three follow-up interviews were conducted before data saturation was achieved. The data gathered during the interview process by the researcher were transcribed and coded by an independent coder using Tech’s model for data analysis. Ethical considerations were adhered to throughout the research study. The aspect of trustworthiness according to Guba’s model was implemented in the research study and included credibility, applicability, consistency and neutrality. iii One theme, two sub themes and categories were identified relating to the diverse experiences expressed by the participants relating to the management of health services being rendered to TB patients. The experiences expressed by the professional nurses included both negative and positive experiences. The negative experiences expressed by the participants were for example, a lack of resources as hampering adequate service delivery, a concern regarding the number of staff contracting TB due to a lack of infection control measures, a difference in conditions of service between the two local authorities and the DOTS supporters as being a threat to patient confidentiality. The positive experiences expressed by the participants included experiences relating to job satisfaction in rendering TB health services, the DOTS supporters as being supportive to the staff, the TB meetings serving as an appropriate platform for problem solving and the audits conducted by managers as being remedial. The study concludes with recommendations made with regard to the areas of nursing practice, education and research.

  • Description: After 1994 with the inception of the South African Democratic Government, the health care delivery system was one of the areas that had to be reviewed. The vehicle for a comprehensive health care system was based on primary health care which encouraged people and patients to take responsibility for their health by being involved in all aspects of their care. For this purpose the Batho Pele principles were introduced, a concept which is informed by 8 principles, namely: consultation, service standards, access, courtesy, information, openness and transparency, redress and value for money. These principles are meant to restore the dignity and the rights of patients which are paramount in the Constitution of South Africa. (Constitution of South Africa 108 of 1996 Chapter 2) The nurses claim that since the introduction of the Batho Pele Principles, patients and their families have been “impossible” towards nurses, making unnecessary and sometimes impossible demands. The nurses also experience patients and their families as being informed of their “rights” but not of their responsibilities as patients. They were also unaware of the rights of the nurses. The objectives of the study were:- To explore and describe the experiences of professional nurses working in the outpatient departments of the introduction of the Batho Pele principles in state hospitals, and to Recommend guidelines that will enhance better understanding and implementation of the Batho Pele principles by the professional nurses. The study is founded on a qualitative research paradigm based on explorative, descriptive and contextual framework. The data was collected from focus groups from each hospital of the Port Elizabeth Hospital Complex. Each group consisted of four to six willing participants all of them were professional nurses who have worked at least five or more years in the outpatient department of the Port Elizabeth Hospital Complex. Data was collected via semi-structured audio-taped interviews together with the researcher’s field notes. Data analysis was done using Tesch’s data analysis spiral. The assistance of independent coder reinforced the truth value of the findings. Themes and subthemes emerged from the data that was collected and revealed that the professional nurses experienced that the Batho Pele Principles as a good policy, but that it was difficulty to uphold due to inadequate planning of health services prior to implementation of the Batho Pele Principles. They experience not getting from their management and they also experience that there was lack of discipline in their institutions. Based on these findings, guidelines that will recommend better implementation of the Batho Pele Principles by nurses were compiled by the researcher and future research in this regard was recommended.

  • Description: This research project investigates the reasons why parents are not fully involved in school governance of a selected school in the Sisonke District of KwaZulu-Natal. As a professional educator the researcher has noted that within the rural communities, especially those in KwaZulu-Natal, an area which he knows intimately, there is a general lack of involvement on the part of parents in the way in which schools, that are educating their children, are being run. The researcher has observed that the parents‟ overall contact with the school is very limited - often confined to the beginning of the school year. Thereafter the parents withdraw from all matters pertaining to the running of the school, in effect abdicating their contribution to their children‟s education by handing over all responsibility to the teachers. This, in turn, has created a demarcation that has divided the teachers and the parents, with the parents‟ input stopping at the school gate, in a manner of speaking. What should be a combined effort of both parents and teachers to achieve the best possible results for the learners, has become a rift. And, as with all splitting of resources, this has had a negative impact on the functionality of these educational institutions. In order to get insight into the possible reasons why this is as it is, the researcher collected data, primarily interviews with parents, teachers and learners. Observations of governing body meetings, parents meetings and school management meetings were also conducted. In addition to these, minutes of meetings of the school related to other relevant documents, for example, school finance committee meetings, were also examined. The approach used in this study is the qualitative study method. The researcher also tried to determine to what extent, if any, factors such as lack of knowledge, lack of experience in school governance, lack of time, insufficient training to capacitate parents for school governance, low levels of education, lack of communication, no invitations being extended from the principal, and also teachers' and parents‟ attitudes contribute to this serious lack of parental involvement in the governance of this school. Another consideration was whether educators and learners have any knowledge that parents have a right to come to school and assist with the activities in the classroom. In essence, all the research hinged on the core question: „What are the explanations for the lack of parental involvement in public schools?‟ From the data gathered, the researcher then suggests or recommends possible solutions to rectifying what is fundamentally a misunderstanding of responsibilities, in order to propose means to rectify the situation for the future benefit of the learners. It is also recognised that due to potential limitations of the study, further studies on the effects of parental involvement in schools‟ governance may need to be undertaken. To get a clearer representation of the extent and where this impacts on our society as a whole, the researcher suggests further studies to encompass other school models, as well as other schools with different racial and social/economic compositions be undertaken.

  • Description: South Africa has over the years and particularly since the enactment of our new Constitution, attracted an increasing number of foreigners. One of the main problems associated with the large number of illegal immigrants in this country is that they are placing strain on South Africa‟s already scare resources such as housing and healthcare. A further problem is that these illegal immigrants are competing with South Africans for jobs which are already scarce, and thus aggravating the unemployment situation. Nevertheless, these illegal immigrants are being employed and by virtue of their circumstances are easily exploited and often the victims of cheap labour, corruption, eviction and assault. Given that these workers are illegal immigrants not in possession of the required work permits, their employment is prohibited by the Immigration Act 13 of 2002. They are thus illegal workers. Another category of illegal workers are those, predominantly women, who are employed in an industry which offers easy income with no contractual obligations – the prostitution industry. Despite the prohibition of prostitution by the Sexual Offences Act 23 of 1957, the prostitution industry throughout South Africa continues to exist. These workers are also particularly vulnerable and easily exploited and abused by their employers. Illegal immigrants and sex workers in South Africa have until recently been denied access to the protection of our labour legislation, by virtue of the illegality of their employment contracts. However two recent controversial decisions, that of the Labour Court in the Discovery Health case, and that of the Labour Appeal Court in the Kylie case, have changed this position.

  • Description: It is the 21st Century and the world is a global village. The development of technology like Information and Communication Technology (ICT) has thus become the dominant means of communication. Education has not been left out of this wave of change. In many countries Information and Communication Technology (ICT) has a clear impact in the development of educational curriculum. This cannot be said about South Africa where huge disparities in terms of ICT related resources still exist. There is a range of uses of ICT in South African schools and it varies according to the economic and social conditions where that school is located. For example, the former Model C schools are well-resourced in terms of computers and access to internet whilst township schools lack these resources. In township schools very few students are exposed to computers due to the limited number of computers and lack of properly qualified educators in the field of ICT. In the Nelson Mandela Bay area township schools only offer CAT (Computer Applications Technology) as an ICT related subject whilst the former Model C schools offer CAT and IT (Information Technology).This treatise attempts to show the digital divide that still exists between a former Model C school and a township school, and the impact it has in quality of education in these schools.

  • Description: The main aim of this study was to explore and describe the general and emotional development of a sample of South African children between the age of five and eight years in residential care. More specifically, the study aimed to explore and describe the general level of development of a sample of children in residential care; to explore and describe the development of a sample of children in residential care in six areas of development; and to describe the emotional wellbeing of children in residential care. A non-probability, purposive sampling method was applied as the participants were comprised of children between the ages of 5 and 8 years housed at the residential care facility. The sample consisted of 11 children. The multiple case study method was used to achieve the aim of the study, using both qualitative and quantitative data. The quantitative data consisted of scores obtained from the administration of the Griffiths Mental Development Scales - Extended Revised (GMDS-ER). The qualitative data was obtained from the Human Figure Drawing (HFD), participants’ scholastic progress reports, case reports from the residential care facility and clinical observations during the assessment period. The data was analysed according to thematic analysis. The results highlighted the pervasiveness of delays in all domains of child development of children housed in residential care, specifically that of language, social and emotional development. An important finding of the study was that decrements in these domains of development underpinned delays in the other domains of development since they form the foundation of learning and relating to the world. The study served to emphasize the importance of consistent developmental assessment in order to ascertain whether these children present with developmental delays and, if so, to xv identify which areas of development are most affected. Information from the developmental assessments could assist in the early identification of developmental delays and allow for individually tailored interventions to overcome such delays.

  • Description: The main aim of this study was to explore and describe the development and cognitive ability of a sample of children aged six to eight enrolled in specialised education, in the category of specific learning disability (SLD). This was achieved through the utilization of the Griffiths-Mental Development Scales – Extended Revised, the Wechsler Intelligence Scales for Children – Fourth Edition and input from the trans-disciplinary team. A non-probability, purposive sampling method was employed and the sample consisted of eight participants. The multiple case study method was used in order to achieve the aim of the study. Both qualitative and quantitative data were incorporated to provide a holistic description of the participants. Quantitative data was obtained from the Griffiths-Mental Development Scales – Extended Revised, the Wechsler Intelligence Scales for Children – Fourth Edition while qualitative data was obtained from the Biographical Questionnaire, input from members of the trans-disciplinary team, data from the participants‟ archives as well as clinical observations made during the assessment process. The data was analysed according to the domains of childhood development.The results obtained revealed that the general development of the sample as measured by the Griffiths-Mental Development Scales – Extended Revised was average. The Eye and Hand Co-ordination Subscale was the most problematic for the participants. The majority of the sample obtained below average scores on the Wechsler Intelligence Scales for Children – Fourth Edition‟s full scale IQ (FSIQ). The Verbal Reasoning Index and the Working Memory Index yielded the lowest scores amongst the sample. The results indicated that the majority of the participants are stronger with non-verbal as opposed to verbal reasoning. The study revealed that the two measures, the Griffiths-Mental Development Scales – Extended Revised, the Wechsler Intelligence Scales for Children – Fourth Edition complement one another. The developmental and intellectual nature of the measures allow for gaps left by the one measure to be filled by the other. The study highlighted the importance of gaining information from the trans-disciplinary team and not relying purely on psychometric measures. It was made clear through the study that deficits often exist that are not picked up by assessment measures alone. In order to gain a comprehensive, holistic picture of a child, one needs to consult a variety of sources. Questions regarding the classification system of high needs learners as well as the current system of specialised education were raised.

  • Description: Prestonella bowkeri and Prestonella nuptialis are montane specialists endemic to the southern Great Escarpment of South Africa. Phylogeographic analyses of these species based on mitochondrial markers CO1 and 16S reveal extremely high levels of divergence between populations indicating a lack of gene flow between populations. This is not surprising, because P. nuptialis and P. bowkeri have limited dispersal capacity, low vagility, a highly fragmented distribution and are habitat specialists that are restricted to isolated mesic refugia associated with waterfalls and montane seepages. A relaxed Bayesian clock estimate suggests that populations diverged from one another during the mid-late Miocene (12.5-7 MYA) which coincides with the modern trends of seasonal aridity which began during the Miocene. This result should be viewed with caution because the rates used are at best imprecise estimates of mutation rates in snails. There is no clear dichotomy between the two species and P. bowkeri is paraphyletic with respect to P. nuptialis, as a consequence the taxonomy is unclear. Due to the high levels of sequence divergence between populations they may be considered as evolutionary significant units (ESU’s). An assessment of haplotype diversity (h) and nucleotide diversity (π) reveals that populations in the western part of the Great Escarpment are more genetically depauperate than populations in the east. Correlations between genetic diversity and climatic variables show that genetically depauperate populations are found in areas that have lower annual rainfall, less reliable rainfall and higher potential evaporation, all factors associated with a drier, less mesic environment that increases the chances of a population bottleneck. This indicates that a shift towards a more arid environment may be a driver of genetic erosion. Historical climate change may thus have affected the amount and distribution of genetic diversity across the Great Escarpment since the Miocene. This has serious future implications for the survival of Prestonella. With predicted increase in global temperatures, climate change in South Africa is likely to result in range contraction and an eastward range shift for many species in the drier central and western areas (Erasmus et al. 2002) and regions along the Great Escarpment are likely to become more arid. Prestonella populations found living on inselbergs along the Great Escarpment are already restricted to site specific watercourses and seepages. An increase in the periods between stream flow, and increasing rainfall variability and mean annual potential evaporation are likely to have an adverse affect on species living in these habitats, resulting in further bottlenecks and possibly local extinction. An IUCN assessment of P. nuptialis and P. bowkeri suggests that these two species are probably endangered. The issue surrounding the conservation of Prestonella species is that they are threatened by global climate change, which cannot be simply restricted or prevented, which makes dealing with the threat of climate change difficult. Assisted migration (MA) may be considered as a method to prevent possible future extinctions of Prestonella populations, but will only be considered as a last resort. The thermal tolerance (Arrhenius breaking temperature and flat-line temperature) of individual snails from three Prestonella populations (one forest population and two thicket populations) were assessed using infrared sensors that detected changes in heart rate with increasing temperature. The forest population had a significantly lower Arrhenius breaking temperature (ABT) and flat-line temperature (FLT) than the two thicket population (p<0.05). Our results do not show a correlation between upper thermal limits and maximum habitat temperatures or other climatic variables in Prestonella populations. Although no correlation is found between ABT and maximum habitat temperature, it is likely that the differences seen between these populations are due to local micro-climate adaptation. The climatic variables used in this experiment are coarse estimates from GIS data and do not reflect actual microhabitat conditions. Forest environments are less heat stressed than thicket environments due to the forest canopy which may explain the lower ABT and FLT of the forest population.

  • Description: The Orange-Fish and Cookhouse tunnels that are part of a major inter-basin water transfer scheme (IBT) act as a pathway for several fish species from the Orange River system to enter the Great Fish and Sundays River systems in South Africa. These include Labeo capensis and L. umbratus. Labeo capensis was restricted to the Orange River system before the inter-basin water transfer scheme. Labeo umbratus occurred naturally in the Orange River and in southern flowing river systems. Previous studies showed that the two species hybridise in Hardap Dam, located in a tributary of the Orange River system in Namibia. There are also unconfirmed reports of hybrids from Darlington Dam on the Sundays River system. The aim of the thesis was to confirm hybridisation in Hardap Dam, assess whether hybridisation between L. capensis and L. umbratus has occurred in Darlington Dam and to gain a better understanding of the diversity of these two species. Morphology (morphometrics and meristics), a nuclear S7 intron and the mitochondrial cytochrome ♭ gene were used to assess for hybridisation. A total of 275 specimens were analysed from across the geographical range of the two species. The two species could be distinguished using morphometrics (dorsal fin base, interorbital width and operculum to eye distance) and meristics (lateral line, origin of the dorsal fin to lateral line, origin of the pelvic fin to lateral line and caudal peduncle scale counts) characters. Hybrids from Hardap and Darlington dams were placed between the two species clusters. Labeo umbratus from the Orange River and southern flowing rivers formed a single cluster. The two species could also be distinguished from each other with six nuclear DNA mutations and hybrids were heterozygous at such sites in both dams. Labeo umbratus populations from the Orange River and southern flowing rivers (Gouritz, Gamtoos, Sundays, Bushmans, Great Fish and Nahoon) formed a single lineage. Analysis of mitochondrial DNA, however, revealed that L. umbratus populations from the Orange River and southern flowing rivers were two lineages that differ from each other by 5 mutations. Labeo capensis could be differentiated from both these lineages. Being maternally inherited, mitochondrial DNA did not reveal hybridisation, but ten specimens with L. capensis haplotypes were found in the Darlington Dam. In Hardap Dam, however, it appears that only L. capensis mitochondrial DNA haplotypes persist, despite morphological and nuclear DNA analysis suggesting that both morphs and hybrids of the two species occur. The genetic integrity of these Labeo species has therefore been compromised in at least Hardap and Darlington dams. The Great Fish and Sundays populations are considered to be under threat of complete introgression. The Kat River and Slagboom Dam populations that were isolated before the IBTs have to remain isolated to protect the genetic integrity of the southern lineage of L. umbratus in these two systems.

  • Description: The name Albuca caudata Jacq. has been widely misunderstood or even ignored since its description in 1791. After studying herbarium specimens and living populations in South Africa, plants fitting Jacquin´s concept of that species are found to be widely distributed in the Eastern Cape, mainly in the Albany centre of Endemism. Furthermore, some divergent specimens matching Baker´s concept of Albuca caudata are described as a new related species: Albuca bakeri. Data on typification, morphology, ecology, and distribution are reported for both taxa. Affinities and divergences with other close allies are also discussed.

  • Description: This study sought to investigate the practices of citizen journalists in the Iindaba Ziyafika project. The objectives of the research were to explore the evolving practices of citizen journalism in Grahamstown and to extrapolate how citizen journalists are securing a discursive space in relationship to conventional journalism. The study investigated whether the citizen journalists based at Grocotts Mail and Radio Grahamstown are developing practices and patterns that can be distinguished from the practices of conventional journalism. It also evaluated whether the content that is produced by citizen journalists differs from the content that is produced by professional journalists, so that it can be understood as "alternative" and as promoting engaged citizenship. A sub goal was also to explore whether citizen journalism does enable the practice of citizenship through expanding the public sphere. The findings of the research are that in the Iindaba Ziyafika project, citizen journalists see news as a process and not as a series of news events. This is clear departure from event-based news conceptualisation associated with mainstream journalism. They view news as unfolding social processes, allowing citizen journalists to question the factors which would have precipitated the event and investigate the causal factors of particular phenomena. The research also reveals that citizen journalists in the project are engaging in pro-am journalism. Part of the practice of citizen journalists involves a very significant amount of collaboration between professional journalists and citizen journalists. The collaboration is in the production of content and in the presentation of radio broadcasts. Part of the findings of the study are that journalists in the Iindaba Ziyafika project work in different mediums and this calls for them to acquire the competencies of the different mediums. The same citizen journalists produce content for print, radio and for online media. The diction used in the stories published by citizen journalists is couched in struggle and revolutionary language which seems to pit the community against the authorities. The citizen journalists also make use of every daily language in their radio broadcasts and borrow from their cultural expression. This they do through populist methods. The citizen journalists have also integrated communication brokering as part and parcel of their practice. This is because the citizen journalists have also made it their mandate to enable the flow of information between the residents and the local authority. In terms of sourcing there is a deliberate stance to include those who are not ordinarily given a voice in the mainstream media. Women and the poor appear frequently in stories as sources and this is a different scenario from that prevalent in mainstream journalism which frequently covers the rich and the powerful. The citizen journalists in the Iindaba Ziyafika project have also borrowed practices from professional journalism and this has been integrated into their daily practice. This includes following strategic rituals of journalism objectivity and balance.

  • Description: Today‘s customers expect zero defects with just-in-time (JIT) delivery from their suppliers, for the specified quantities, as a matter of standard practice. More importantly, customers expect companies to help them know what they need in terms of quantities and quality now, and for the future. No other change process adds long-term value as quickly as zero defects. Companies failing to embrace this quality culture face difficult challenges. To achieve this level of performance requires tremendous focus in an organisation and throughout its supply base. Business models around the world are changing dramatically from the "Source Local" to the "Source Anywhere and Build Anywhere" model (Cummins, 2008: 19). Companies have shifted away from a hierarchical, one-dimensional, supply chain entity to a fragmented network in favor of strategic partnerships with external entities. Many businesses facing such models are experiencing challenges and, if not managed correctly, can find themselves struggling to compete in this new landscape. Thus, when price concessions are so stringent, quality has to suffer. To reduce costs, suppliers are forced to seek less expensive ways to produce parts and components. Does this mean the use of different, less expensive materials? Does this mean less skilled labor? Does this mean production shortcuts? Or does this mean that suppliers just bite the bullet and pay the price? Once all the costs have been extracted from the supply chain, the only thing left to suffer is quality. The underlying objective of this research is to investigate the impact of delivery performance for a selected part at General Motors South Africa. In order to develop a research strategy to deal with, and solve, the main problem, the following research questions have been identified: a) What can be learned from literature about the impact of quality costs? b) Why is this specific part a suitable candidate for a cost investigation? c) What are the processes involved if a defect occurs? d) How can the cost be estimated? e) What effect does poor supplier quality have on productivity? This dissertation aims to investigate the problems and challenges General Motors South Africa are facing pertaining to the delivery performance of a selected part. The dissertation will also strive to highlight the impact of poor supplier quality on productivity and the related cost implications. Conclusions and recommendations will furthermore be outlined.

  • Description: This study focused on assessing the condition and creating a carbon inventory of forests in the Matiwane area of the Transkei. This entailed the use of aerial photography in tracing forest cover change from 1942 to 2007 coupled with ground-truthing to assess whether the forests have in any way endured degradation over the years with a potential reduction in carbon stocks as a result. This study revealed both the loss and gain of biomass in the area with a general trend of forests being continuously converted to agricultural fields resulting in reduced forest area, stem density, tree density and carbon loss in different pools of the forests, reflecting that these forests are degraded. The conversion has resulted in the reduction in the number of species from a mean of 11±0.57 species/200m² in intact forests to 1±0.23species/200m² plot in degraded forests. It was also revealed that approximately 5.2 % (791 hectares) of 15 352 hectares of forest area was lost as a result of the conversion of forest land to agricultural fields from 1942 to 2007 with 99 % of the clearing occurring in the last 33 years (1974-2007) and of which 60 % ( 4 77 hectares) occurred from 1995 to 2007, indicating that forest degradation in these forests is on the increase. The assessment also revealed some areas that were nonforest in 1942 that have accumulated woody biomass (BAA), composed mainly of Acacia sp accounting for 51.18 MgC.ha⁻¹ (Megagrams of carbon per hectare) and total carbon stocks of 0.02 TgC (Teragrams of carbon). The degradation of these forests induced a reduction in carbon stocks from 311.68±23.69 MgC.ha⁻¹ (to a soil depth 0-50 cm) in intact forest to 73.46±12.34 MgC.ha⁻¹ in degraded forests. The total carbon stocks in the degraded forests were approximated at 0.06 TgC and the BAA areas 0.02 TgC with 4.7 TgC in intact forests. The degradation of these forests has resulted in the net carbon loss of 0.19 TgC between 1942 and 2007 but 4.76 TgC is still locked in these forests. The large difference in carbon stocks between intact and degraded forests indicated the need to reduce the degradation of these forests to prevent further carbon loss and reduction of the carbon sequestration potential of these forests.

  • Description: The aim of this descriptive study was to explore the impact of HIV/AIDS on the maternal health programme at selected Primary Health Care (PHC) clinics in the Peddie sub-district, in the Eastern Cape, South Africa. This study showed that the HIV/AIDS epidemic has had major influences on the rendering of maternal health services in this sub-district. An understanding of the impact of HIV/AIDS on the delivery of the maternal health programme in the Peddie Primary Health Clinics will potentially help the District Health Service office, as well as the clinic managers and professional nurses to formulate strategies to strengthen the maternal health programme. This data will also be helpful when developing plans to cope with the heavy work-load of the clinics offering maternal health services, and to address the attitudes and concerns of the professional nurses working in the PHC clinics in this area. Thirty professional nurses working at 10 clinics responded to the questionnaires which elicited questions pertaining to the impact of HIV/AIDS on the rendering of their services. As part of the data gathering procedures, standardised notice boards at the PHC clinics were used to document the services rendered. The numbers of ANC clients attended to each of the clinics per week were collected in routine attendance tick registers used in the clinics for recording and monitoring statistics in the maternal health programme. The data was analysed to examine the possible impact of HIV/AIDS on maternal health services rendered by registered nurses/midwives working in the PHC clinics. The registered nurses who responded to the questionnaires (Annexure H) made several suggestions. These included the following: (i) encouraged more training (11 nurses), (ii) addition of more staff members, (iii) to have specialized staff for management of maternal HIV. Because of the study limitations such as the sample size of 10 clinics with a total of 30 nurses who were studied, the study may not be generalised to the whole of the Eastern Cape Province. The study however did provide baseline information on the impact of HIV/AIDS on the maternal health programme. The study findings were that HIV/AIDS has had an impact on the delivery of the maternal health programme due to the extra services brought about by the response to the HIV/AIDS pandemic. This study will contribute to a better understanding of the impact of HIV/AIDS on the maternal health programme at the PHC level in Peddie. The research provided insight into issues that are crucial to the delivery of maternal health programmes in rural areas. , Thesis (MCur) -- Faculty of Science and Agriculture, 2011
