- Description: Through an exploration of both sculptural and thought processes undertaken in making my Masters exhibition, ‘Hippocampus’, I unpack some possibilities, instabilities, and limitations inherent in representation and visual perception. This thesis explores the Hippocampus as image (seahorse) and concept (brain-structure involved in cognitive mapping of space). Looking at Gilles Deleuze’s writings on representation, I will expand on the notion of the map as being that which does not define and fix a structure or meaning, but rather is open, extendable and experimental. I explore the becoming, rather than the being, of image and concept. The emphasis here is on process, non-representation, and fluidity of meaning. This is supportive of my personal affirmation of the practice and process of art-making as research. I will refer to the graphic prints of Maurits Cornelis Escher as a means to elucidate a visual contextualization of my practical work, particularly with regard to the play with two- and three-dimensional space perception. Through precisely calculated ‘experiments’ that show up the partiality of our visual perception of space, Escher alludes to things that either cannot actually exist as spatial objects or do exist, but resist representation. Similarly I will explore how my own sculptures, although existing in space resist a fixed representation and suggest ideas of other spaces, non-spaces; an in-between space that does not pin itself down and become fixed to any particular image, idea, objector representation.

- Description: The rationale of my research was to make sure that all learners are treated as equals in the education afforded to them. The researcher noticed that not all educators in mainstream schools facing learners experiencing learning problems could deal with the Curriculum and that many had difficulty in coping in an inclusive classrooms setting. Furthermore, the researcher noticed that many educators percieve that they did not have the knowledge and skills to identify and support learners experiencing learning problems. Consequently, the educators felt that they could not effectively help these learners in their learning progress. While the educators struggle to cope, learners ended up having to repeat a grade or being promoted to the next grade without having attained the neccesary skills yet. The researcher set out to research what the available literature stated about how educators could be empowered to cope with teaching learners experiencing learning problems in an inclusive classroom situation. For this research study, a qualitative approach was followed, as it best matched the type of interactive investigation considered necessary. Due to time, financial and resources constraints, purpose sampling was used as the most effective method of yielding data. The qualitative approach embraced a multi-perspective approach, in terms of which methods of data collection were used, such as collection questionnaires, conducting interviews and using observations. The researcher trusts that her understanding as presented in the research findings and the recommendations made will benefit not only herself, but will empower all educators coping with the stress of teaching learners experiencing learning problems and improving their skills and self-esteem in the educational environment.

- Description: This study examines the current curriculum for primary schools in South Africa – Curriculum 2005 (C2005) and the subsequent Revised National Curriculum Statement (RNCS), with Outcomes-Based Education (OBE) as its fundamental educational approach - with specific reference to the place of music education in it. While the underlying principles and scope of this curriculum has many positive attributes, numerous studies have shown that there are still major stumbling blocks in the way of its successful implementation. Since the emphasis of the Arts and Culture Learning Area is on the nurturing of generic values and attitudes towards culture, it does not provide for sufficient development of subject-specific musical skills and knowledge. Instead this vital form of musical learning continues to be provided in the form of extra-curricular music programmes by those few schools who have the staff expertise and the funding to do so. Music therefore remains accessible only to the privileged few. .Although C2005 encourages and requires significant levels of integration in Learning Outcomes and Assessment Standards within and across Learning Areas, this is currently one of the least successful aspects of its implementation. This lack of success, it is argued, is in part the result of severe limitations in the training of teachers and the availability of necessary resources in schools, and in part the result of the curriculum’s own limited interpretation of integration. Psychologist Dr Howard Gardner’s Theory of Multiple Intelligences is a holistic approach to education that stresses, amongst other things, that Musical Intelligence is one of eight vital forms of intelligence that should be accessible to all children. It is argued that educational approaches based on Gardner’s Multiple Intelligences Theory provide some insights into the integration of Musical Intelligence with other forms of learning that may usefully be applied in C2005.

- Description: This thesis spans two fields - South African dance and the philosophy of humour - and attempts to link them through an understanding of their formal mechanisms. I attempt to establish two main ideas: that there is a need for a critical praxis in South African dance, and that humour in dance can be part of this process. In Chapter One, I discuss elements of the South African dance and theatre industries pre- and post-1994 towards arguing my first point (that South African dance would benefit from a critical praxis). I probe some of the challenges facing artists and describe howchoreographers are dealing thematically and stylistically (but not formally) with the concept of the 'New' South Africa. Through an investigation of concerns voiced by critics regarding choreographic form in the country, I argue that South African dance would benefit from critical formal investigations in dance-making. Finally, I discuss traditional views of humour in South African dance/theatre and in philosophy, which suggest that humour is predominantly seen as frivolous and unworthy of serious attenfion. In Chapter Two, I offer a defence for humour's more profound critical aspects, suggesting that humour can in fact be seen as critical 'thinking in action'. A discussion of theories about humour reveals that the basis for humour is the incongruous. A subsequent discussion of form in theatre and dance shows how the incongruous might work within dance form to create meta-dance. In this way, I attempt to link the two fields of humour and South African dance and to make the connection between the critical capaci~ies of meta-dance and those of humour. I suggest, in other words, that humour in dance can create a critical awareness, of the likes advocated in Chapter One. In Chapter Three, I discuss aspects of two works: my own This part should be uncomfortable (2008) and Nelisiwe Xaba's Plasticization (2004). The two analyses differ from each other as does the humour in both works. Despite the differences, I argue that humour in both works is operating on a critical level that includes a meta-level of signification.

- Description: South Africa, with an estimated 5.7 million people living with HIV, continues to have one of the largest epidemics in the world. The introduction of HAART resulted in prolonged and improved quality of life of many infected patients. However, adverse effects caused by these drugs have become a major concern as they affect the adherence of patients and in some cases even result in the death of patients. Although much research has been and is still being conducted in the area of understanding, preventing and management of ARV adverse effects, there is still a need for patients to be actively involved in self-monitoring for adverse effects. This will assist health care professionals in early identification of serious or potentially serious ARV effects. This study aimed at evaluating the usefulness of strategies developed and employed in the identification, recording and monitoring of adverse effects. The study was conducted with patients receiving HAART from a private HIV and AIDS clinic in Uitenhage, Eastern Cape, South Africa. The research project was approved by the Nelson Mandela Metropolitan University Research and Ethics Committee and the research site. This was an experimental, randomized controlled study carried out over a period of three months (August to October 2009), with a sample size of 160 patients divided into four study groups of 40 patients each. Two monitoring strategies, namely an ARV adverse effect monitoring tool and a patient self-monitoring diary were developed and used for the identification and recording of adverse effects. The four study groups included a Control group, a Tool group, a Diary group and a Tool-Diary group. Willing patients, after signing an informed consent form, were randomly assigned to one of the four groups by participating health care workers at the study site. Data was retrieved from the patient files by the researcher. Descriptive statistical analysis of the findings of the study was conducted using SPSS®. One hundred and forty nine patients were included in the final data analysis. Of the 80 diaries handed out to patients, only 33 were returned and due to errors only 31 were suitable for analysis. Monitoring tools were completed and analysed for 36 patients. The tool was found to be more effective in identifying adverse effects of a physical nature (such as peripheral neuropathy and lipodystrophy) than the usual methods of monitoring employed by the clinic, whilst the diary, used alone, was found to be less effective. Use of the tool and diary combined resulted in the most significant identification and recording of central nervous system related adverse effects and physical adverse effects. However due to the low return rate of the diaries and the majority of the monitoring tool not being completed in many instances the results of this study may not be generalisable. The study results did however suggest that combining the tool and the diary methods of adverse effect identification, yielded the most favourable results when compared to each method alone. This may be attributed to the fact that the tool is useful in identifying objective symptoms and the diaries subjective symptoms, particularly in instances where the patients forget to report their symptoms to healthcare professional whilst at the clinic. The diaries were also reported to improve adherence for more than 90 percentage (n=31) of the patients. More research would be needed in order to verify the exact significance of the tool and the diary in identifying and recording adverse effects and symptoms of adverse effects.

- Description: Cryptosporidiosis is an infection caused by Cryptosporidium; a protozoan parasite that infects the gastrointestinal tract. The infection is of major public health concern in both developed and developing countries. Faecal samples were collected from 160 in-patient adults, with complaint of diarrhoea, admitted at Victoria hospital in Alice, Nkonkobe Municipality. Twenty apparently healthy subjects were included as controls. All diarrhoea positive patients were interviewed to record socio-demographic information, water supply and animal contact. Initial screening was carried out by microscopy and ELISA to detect positive Cryptosporidium. Genomic DNA was extracted from microscopically positive samples and a PCR reaction was perform to amplify the (18S) SSUrRNA gene for further identification and epidemiology of Cryptosporidium. Data were analysed using Pearson‘s χ2 and Fisher‘s exact test to assess the univariate association between Cryptosporidium infection and the possible risk factors. Of the 180 subjects screened for cryptosporidial infection, Cryptosporidium antigen was detected in 122 giving an overall prevalence of 67.8 percent. In HIV-positive diarrhoea patients, prevalence increased with ages; between 31-43 (mean age 36.5 yr) and 70-82 (mean age 75.8 yr) had a higher prevalence (100 percent) of the antigen than 18-30 (mean age 23.2 yr) and 83-95 (mean age 88.8 yr) (50.0 percent) in HIV-positive diarrhoea patients (P > 0.05). In HIV-negative diarrhoea patients, prevalence was highest in the 18-30 (mean age 23.2 yr) (87.5 percent) and least (35.7 percent) in those aged 83-95 (mean age 88.8 yr) (P > 0.05). Cryptosporidium antigen was higher in females than in males. Of 115 females (mean age 46.7yr) who participated in the study, antigen was detected in 90 (78.2 percent) against 32 (71.1 percent) of 45 males (mean age 42.6yr). None of the 20 apparently healthy control subjects was found to be infected with Cryptosporidium. Cryptosporidium was detected in 27 HIV-positive and 97 HIV-negative diarrhoea patients by any one of the techniques. Antigen detection by ELISA 14 showed the highest positivity 96 (76.8 percent) in HIV- negative and 26 (74.3 percent) in HIV- positive diarrhoea patients. PCR detected eighty-nine (71.2 percent) cases in HIV-negative and 23 (65.7 percent) in HIV-positive patients with diarrhoea. Only 13 (37.1 percent) HIV-positive and 34 (27.2 percent) HIV-negative diarrhoea patients were found positive for Cryptosporidium by modified ZN. No significant difference was observed in sensitivity of antigen detection by ELISA and PCR (96.9 percent) in HIV-negative diarrhoea patients, respectively. Specificity of the staining technique was 88.9 percent in HIV-positive and 96.6 percent in HIV-negative diarrhoea patients. No significant difference was found in specificity of antigen detection by ELISA and PCR in HIV-positive and HIV-negative diarrhoea patients, respectively. Positive predictive value of ZN staining in both HIV-positive and HIV-negative diarrhoea patients (92.3 and 96.9 percent) was statistically higher than ELISA and PCR. No significant difference was observed in negative predictive value of ZN technique for detection of Cryptosporidium between HIV-positive and HIV- negative diarrhoea patients. Differences found in prevalence rates due to water source, suggest that the high infection rates of specific groups are associated with their exposure to the contaminated water supply. The results indicate that Cryptosporidium infection is highly prevalent in adult faecal specimens in the Nkonkobe Municipality, an indication of active infection that is likely to emerge as major human pathogen in this location due to socioeconomic changes which favour transmission. However, sequencing analysis is required to differentiate between Cryptosporidium genotypes in the various outbreaks

However, sequencing analysis is required to differentiate between Cryptosporidium genotypes in the various outbreaks

- Description: In this study, Local Economic Development (LED) is defined as an outcome of processes aimed at building up the capacity of local areas for sustainable economic development. The study assesses whether LED interventions, especially agricultural programmes, improve the livelihoods of poor communities in the Amathole District Municipality. Data was collected by use of both qualitative and quantitative research methods through interviews and questionnaires, respectively. Probability and non-probability sampling techniques were used to identify the research sample from the target population. These were further broken down into stratified, purposive and snowball sampling to enable the researcher to select specific municipalities, councillors, officials and stakeholders who participated in the study. Budgetary constraints, staff shortages and lack of required skills/ expertise were identified as the main challenges facing the district. The latter makes it difficult for the municipality to effectively implement sound LED programmes. Consequently, LED benefits are minimal. It is, therefore, recommendable for the municipality to seek other means of generating and boosting their financial viability through partnerships and private sector investments. This in turn will generate revenue for the municipality and ensure economic development in the district, thereby making a meaningful contribution towards the realization of a goal for “a better life for all”.

- Description: The study was premised on the truism that men have historically served in higher echelons of organizational management structures and women are under-represented. The principal objective was to explore the constraints faced by women in accessing higher leadership and senior management positions in public, private and non-governmental organisations in Zimbabwe. This study adopted the triangulation method, that is, qualitative and quantitative approaches. These mixed research methods, were upgraded by the feminist research methodologies, thereby making a contribution in the field of research. The study found out that the constraints that mostly hinder women from accessing leadership and senior management positions in public, private and NGOs were cultural practices, which represent levels of power and control that in turn hinder reforms; and women's socialisation into feminised roles. The study also found out that in most organisations, most females work under male leadership, and this traditional organisational culture, needs to be deconstructed and reversed in order to achieve gender equality. The study recommended for a human centric and integrated organizational management strategy for public, private and NGOs in Zimbabwe. The adoption of a human centric and integrated management approach should aim at gender equity and reduce women's under-representation. A human centred organizational culture has to be practiced, that would create organisational ethos that guide organizational management. An integrated organizational management approach should integrate all systems and processes into one complete framework, enabling people to work as a single unit, unified by organizational goals, shared vision and common values. The system should depend on a balanced mix of the masculine and feminine attributes. The approach should put its weight towards adoption of measures to attract, advance and empower women so as to benefit from their qualifications, experience and talent in a highly competitive environment.

- Description: The aim of this investigation was to assess the impact of the In-Field Rainwater Harvesting technology on household food security in the study area. The study was conducted in Nkonkobe Local Municipality of the Amathole District Municipality in central Eastern Cape Province. The areas under investigation are Guquka and Khayaletu villages of the Thyume Valley, which is located about 30 kilometres north of Alice. The method used to assess the impact of the IRWH on household food security was a pair wise comparison method. During September 2009, there were 60 (34 in Guquka and 26 in Khayaletu) households who adopted the technology in home gardens. In order to get a clear picture of the impact of the technology on food security, a decision was taken to assess both the project members and non-project members, hence the pairwise comparison method. The non-project members (also 60 households) were selected randomly from those who were interviewed during the situation analysis in 2004. Five indicators were used to assess household food security. These were household income, expenditure on food, diet diversity, energy-protein intakes, and micro-nutrient intakes (Vitamin A, C and Iron). The income and expenditure data were collected from the 120 households. However, the detailed food data were collected from selected cases from both groups at different times (seasons) of the year. A case study approach was employed in data collection. A total of 12 cases (six households per village) were selected for this investigation. These were selected mainly according to the degree of poverty. The total of six households from each village comprised three project members and three non-members i.e. one from each poverty class (non- poor, poor and ultra-poor) in both categories. The data on the kinds of food products consumed by households was gathered using the food account method (FAM). The food consumed was then analysed for nutrient adequacy. The main findings of this investigation show the IRWH technology to have a positive impact on food security and nutrition of the project members. The technology made significant contributions to the amount of energy and vitamins A and C consumed by households especially during wet seasons. Substantial contributions of garden produce were noted among the project members. However, these contributions were not enough to ensure household food security. The results indicate that there are nutritional problems in the study area. Firstly, there is protein- v energy malnutrition mainly affecting the poor and the ultra-poor households. Secondly, there is hidden hunger affecting all poverty categories, even the non-poor households. This is mainly demonstrated by poor diet quality i.e. diet that lacks essential nutrients identified

- Description: New media technology continues to provide journalists with sophisticated tools that are changing news processing and gathering. Economics journalists in particular have grasped the possibilities offered by new media technologies. Thus, this paper offers a theoretical and practical look at how new media technologies have impacted the production and processing of economics news in South Africa, with a particular focus on Fin24.com which is South Africa's biggest online economics news publication. Using qualitative research methods and the case-study approach, this thesis documents the impact of new media technologies on the production of economics news. It draws on Witschge and Nygren's (2009) framework which describes how new media technologies change the nature in which news is produced and processed. New media technologies in this study will refer to the Internet, particularly search engines like Google, social networking sites such as Twitter and Facebook, Blogs as well as mobile telephony. Economics journalism will here refer to all coverage of economics and business-related news. This is because the case study (Fin24.com) covers both business and economics journalism by strict definition. Findings reveal that these new media technologies have not only changed economics newsgathering and processing but also journalistic routines. The findings generally show that new media technologies make it easier for economics journalists to produce the news quickly and efficiently. Indeed, the most distinguishing characteristic of new media is its overall speed, which is both challenging and attractive. The findings also reveal that new media technologies within a newsroom can be problematic in a number of ways, mainly raising issues of accuracy and credibility thus challenging the profession of economics journalism more than ever.

Impact pf provincial local government support for effective implementation of PMS in municipalities (Lukhanji municipality)

- Description: One of the more frequently heard criticisms of local government is that it is not delivering the required services or it is not delivering an efficient standard of service. Performance management for local government contributes to creating a performance culture in the public service at municipal level. Performance management is a mechanism that is used to ensure that the municipality is doing its work and delivering on its mandate. The SALGA HRD Policy Conference held in March 2003 endorsed the spirit of the relevant legislation on performance management in municipalities. As the employee body and the only recognized voice of municipalities in the country, SALGA has been of the view that the legislative imperative placed on municipalities to be developmental and performance orientated cannot be overly emphasized. Concomitant with the legislative imperative has been the political will or unwavering political commitment to ensure that municipal administrations are accountable to their respective councils, and by extension, the communities they serve. The successful implementation of the Performance Management System at all municipalities will certainly serve as a yardstick in objectively measuring the performance of municipal and provincial local government officials. It is believed that the ongoing measurement of performance will inevitably lead to better delivery of services to our people. The Constitution of South Africa places a developmental mandate on local governments, with the express purpose of them providing effective and efficient services to their communities and to promote local social and economic development. Further to this, the Municipal Systems Act of 2000 provides a legislative framework for municipalities to embark on integrated development planning. Thus all municipalities require an Integrated Development Plan (lDP) to be in place in order to fully realize their objectives as set out in Section 152 of the Constitution. In the interpretation of the legislation, it is clear that the Council (the political body of the municipality) is held responsible to ensure that its municipality has an lDP and PMS in place. Thus both the political principal and the leadership of a municipality are, by law, required to fulfil their obligations in implementing the PMS, while the provincial local government department is charged with the obligation to ensure that such objectives by municipalities are realized by way of providing financial and human capital assistance. Since the lDP and PMS have been legislated in such a manner, it thus becomes legally imperative that municipalities comply with the legislation. The Auditor General is thus required to audit a municipality within this context. Failure to comply may entail certain legal repercussions. Generally, there has been a drive to inculcate improved performance in all three spheres of government. However, it becomes integral that municipalities are performance oriented, especially since it is the sphere of government closest to the grass-roots levels where the real impact of service delivery is experienced. There is undoubtedly a link between lDP and PM. However, it has been observed that both in municipalities and provincial local government there is no synergy between these two components and they tend to operate in isolation of each other. Logically, the scorecards of the organisation and individuals should be derived from the municipality's IDP; however this is not always the case. It is also evident that both the municipality and provincial local government approaches the two issues as different disciplines. Having said this, it is important for SALGA and Provincial Local Government to encourage and ensure better alignment of lDP and PMS in both the province and municipalities.

- Description: The overuse of antibiotics and consequent resistance is a common problem in medical practice worldwide. Switch therapy is a technique that can be applied to streamline antibiotic therapy reducing unnecessary prolonged Intravenous (IV) antibiotic therapy. Antibiotic switch therapy has several other benefits such as: decreasing length of hospital stay; decreasing the incidence of adverse events associated with the administration of IV antibiotics; decreasing direct and indirect hospitalisation costs while improving patients’ comfort and mobility; and decreasing the risk of acquiring nosocomial infections. Certain elements are required to make the implementation of any guideline, including a switch therapy guideline, a success and probably one of the most important is the support from a motivated multidisciplinary team. The role of such a team, in the South African context, would be filled by the Pharmacy and Therapeutics Committee (PTC). In addition, to make a guideline successful it should be continuously implemented. This responsibility traditionally falls to a pharmacist. In the United Kingdom (UK) and the United States of America (USA) pharmacists are used to promote the appropriate use of antibiotics in hospitals as this has shown to have several economic advantages. The objectives of the study were: to determine, by means of a survey, whether guidelines for IV to oral switch were employed in South African regional, tertiary and national government hospitals; to design and implement an IV to oral antibiotic switch therapy (IVOST) guideline for a local public sector tertiary level hospital; to evaluate the effectiveness of guideline implementation; and to capture, via a questionnaire, the perceptions of prescribers regarding antibiotic prescribing, including switch therapy. The Survey of Current IV Switch Therapy Practice Questionnaire was distributed to Responsible Pharmacists at regional, provincial tertiary and national central government hospitals to determine whether IVOST guidelines were employed in South African government hospitals. Following the survey, an IVOST Guideline was designed by the researcher in consultation with the Department of Medicine and the Department of Pharmacy. The IVOST Guideline was implemented following approval by the PTC at a local tertiary level government hospital. A presentation was held for prescribers, guideline documents were distributed, posters were placed in the medical wards and the ward pharmacist/researcher integrated the guideline into daily practice by placing “reminder stickers” in patient medical folders. A pre-implementation audit and two post-implementation audits, each consisting of 150 patient medical records, were conducted and compared to determine the effect of IVOST guideline implementation on prescribing patterns and to determine whether any changes could be sustained. The Prescriber Antibiotic Survey was then conducted to capture the perceptions of prescribers regarding antibiotic therapy, including switch therapy.

- Description: Antiretroviral drugs taken during pregnancy, reduce the rates of mother-to-child transmission from 35 percent to as low as 1 to 2 percent (UNAIDS, 2009). In 2002, the Prevention of Mother-to-Child Transmission (PMTCT) programme was implemented in South Africa. Studies on the implementation of the PMTCT programme have shown that understaffed and under-developed health care facilities were key barriers to the provision of PMTCT services (Health Systems Trust, 2002: 6; Skinner et al., 2003). The aim of this study was to assess the challenges experienced by health care workers working in public sector facilities in the Nelson Mandela Metropole after implementation of the dual therapy PMTCT programme. Four areas were investigated: Infrastructure; Drug Supply Management; Clinic Procedures and Staffing. A quantitative descriptive study was conducted in August 2009 at nine public health care facilities in the Nelson Mandela Metropole, South Africa. Questionnaires were issued to 81 nurses and 41 pharmacy personnel (pharmacists and pharmacist assistants). Checklist audit forms were issued to the Facility Manager of each facility and completed with the researcher. The key findings for Infrastructure were lack of space at patient waiting rooms (9; 100 percent n=9), counselling area (5; 55.5 percent; n=9), nurse consultation rooms (6; 66.6 percent; n=9), storage areas (5; 55.5 percent; n=9) and filing areas (7; 77.7 percent; n=9). The key findings for Drug Supply Management were none of the dispensaries (0 percent; n=10) were fully compliant with Good Pharmacy Practice, pharmacy personnel indicated that there were no stock cards for medication (13; 31.7 percent; n=41); there was less than two weeks supply of buffer stock kept for zidovudine and nevirapine (13; 35.1percent; n=37) and medication orders were placed without any reference to minimum and maximum levels of medication (15; 36.5 percent; n=41) . The key findings for Clinic Procedures were only two facilities followed up on patients that had missed appointments (22.2 percent; n=9) and four facilities (44.4 percent; n=9) had a tracking system for patients that had defaulted. Of the nine facilities only three (33.3 percent; n=9) updated patient demographic details regularly. The key findings for Staffing were a shortage of doctors, nurses, counsellors and pharmacists at the facilities. One of the major challenges identified was the lack of training offered on new PMTCT protocols with 56.2 percent (45; n=80) of the nurses stating that no training was provided on the dual PMTCT protocol. Only 54.3 percent (44; n=81) of nurses stated that they knew the criteria to start the mother on dual PMTCT therapy. In conclusion there is an urgent need for barriers such as lack of staff, lack of space, lack of training on PMTCT and standard procedures for follow up of patients to be addressed in order to ensure the successful scaling up of PMTCT.

- Description: Antiretroviral drugs taken during pregnancy, reduce the rates of mother-to-child transmission from 35 percent to as low as 1 to 2 percent (UNAIDS, 2009). In 2002, the Prevention of Mother-to-Child Transmission (PMTCT) programme was implemented in South Africa. Studies on the implementation of the PMTCT programme have shown that understaffed and under-developed health care facilities were key barriers to the provision of PMTCT services (Health Systems Trust, 2002: 6; Skinner et al., 2003). The aim of this study was to assess the challenges experienced by health care workers working in public sector facilities in the Nelson Mandela Metropole after implementation of the dual therapy PMTCT programme. Four areas were investigated: Infrastructure; Drug Supply Management; Clinic Procedures and Staffing. A quantitative descriptive study was conducted in August 2009 at nine public health care facilities in the Nelson Mandela Metropole, South Africa. Questionnaires were issued to 81 nurses and 41 pharmacy personnel (pharmacists and pharmacist assistants). Checklist audit forms were issued to the Facility Manager of each facility and completed with the researcher. The key findings for Infrastructure were lack of space at patient waiting rooms (9; 100 percent n=9), counselling area (5; 55.5 percent; n=9), nurse consultation rooms (6; 66.6 percent; n=9), storage areas (5; 55.5 percent; n=9) and filing areas (7; 77.7 percent; n=9).

- Description: There are many reasons to believe that budgeting lies at the heart of business management. Gray et al (2001:324) states that ―budgetary planning and control is the most visible use of accounting information in the management control process. By setting standards of performance and providing feedback by means of variance reports, the accountant supplies much of the fundamental information required for overall planning and control. However, Gray et al (2001:324) point out that capital budgeting decision is limited by the intricacies of the international business environment, which is characterized by economic, social, political, and cultural diversity. Therefore, decisions of capital investments and budgetary controls are more problematic (Gray et al., 2001:14). One of the defining characteristics of the globalization of the world economy in the past two decades has been the spread of multinational corporations' activities across countries, and, as a result, significant increases in global foreign direct investment (FDI) outflow in the 1990s (from R233 billion in 1990 to R1, 379 billion in 2000). For example, the total stock of Chinese direct investment abroad nearly tripled over the 1990s (from $2.2 trillion in 1990 to $6.3 trillion in 2000) as Chinese multinational corporations generated an increasingly large share of world GDP (6.8 percent in 1994 and 8.6 percent in 2000). Multinational corporations have become an important conduit in the global allocation of investment funds. However, the business environment in international markets has been considered volatile; there is no reliable and accurate method to aid 2 multinational corporations about decisions about the international environment. Thus, multinational corporations have encountered risk and challenge. Given the development and challenge of the international environment, this study have been considered to plan over a longer time horizon, develop formal mechanisms to set aside funds for preserving existing facilities, increase automation of the process, and link capital planning decisions to statewide performance goals and strategic plans. This research draws upon existing theoretical determinants of capital budgeting and empirically tests the hypotheses across a sample of multinational corporations in China. Although the sample is from China, the results have important implications for multinational corporations based in other countries. This paper is composed of four parts. The first part briefly gives both a theoretical and practical overview of multinational capital budgeting analysis. The second part discusses the data collection techniques and the questionnaire design used in this study. The third part provides some important findings of this research. The last section offers some conclusions from this study.

- Description: All organisations compete on the basis of service. In today‘s highly competitive world, organisations need to compete to retain their customers and to offer good customer service that will give them a competitive advantage. In the South African pharmaceutical market, the introduction of the Single Exit Price (SEP) and generic substitution have led to the price of equivalent medicines no longer being the differentiating factor in a customer deciding which manufacturer‘s product to purchase. The availability of generic medicines at the pharmacy or hospital has become the differentiating factor. Two types of customers exist in any organisation, namely, external customers and internal customers. Much has been written about the external customer, but less about the internal customer. Many managers do not perceive internal customer service as a priority. Any organisation attempting to deliver quality service to their external customers must begin by serving the needs of their internal customers. Internal service quality is characterised by the attitudes that people have towards one another and in the way that employees serve one another inside the organisation. By improving customer service, the organisation can improve its profitability, sustainability and customer retention. The aim of this study was to determine whether the levels of internal customer service between the three sections of Aspen Pharmacare are optimal. Determining the current performance levels between the staff of the sections will assist in highlighting the areas that require attention. The three sections of Aspen Pharmacare that are internal customers of one another and have been used in the study are: - production; - demand planning; and - distribution. The results of the study show that all three sections rate three service quality dimensions (communication, tangibles and reliability) as important. The results were used to develop an internal customer service model for Aspen Pharmacare.

The study has been carried out by means of a literature and a primary study. Effective communication is one of the key elements which contribute to the success of Local Economic Development implementation. The communication strategies in Local Economic Development have been discussed and analysed to determine the ineffective methods of communication in Local Economic Development implementation. The literature indicated that a good communication strategy is determining the most effective method of communicating with ones’ target audience. The findings of the primary study revealed that the communication strategy between the stakeholders was not fully maximised in improving Local Economic Development implementation. It also revealed secondary factors that contributed to the ineffectiveness of Local Economic Development implementation. In order to improve the current communication strategies, the researcher recommended that new forms of communication medium between Government and the Private sector could be introduced. Lastly, the secondary factors which contribute to ineffective Local Economic Development implementation were analysed and recommendations were suggested.

- Description: Learners in the Junior Secondary Phase (Grades 8 to 10) are often required to answer open-ended questions which require a response in the form of an explanation. As frequently reported in the external examiners' reports of Life Sciences, learners do not write adequate explanations as responses to explanatory questions. This thesis reports on action research based on my experience as a Life Sciences teacher trying to address this problem. Therefore, the purpose of this study was to develop suitable, manageable and effective strategies that I could implement in order to improve my teaching of explanation writing skills of in the Junior Secondary school learners with a view to enhance curriculum content knowledge in Life Sciences. The intervention was carried out in a Grade 10 Life Sciences class which consisted of 35 learners. The first cycle consisted of seven lessons carried out over two weeks in normal school time. The main sources of data from my lesson interventions were the learners' written work, their journal entries, the researcher's journal, the field notes from the non-participant observer and interviews with two focus groups. Both the interviews and the lessons were recorded and transcribed. The research data reveals that the ability of the Junior Secondary learners to write explanations was hindered by language problems. In addition, a lack of integration of language issues into the subject content was a contributing factor to their inadequate writing skills. Spelling errors and lack of expression in English second language contribute to the problem of writing good explanations. The data has also revealed that learners‟ writing skills can be improved by implementing suitable teaching strategies, such as the curriculum cycle as proposed by Gibbons (2002). The curriculum cycle can be modified to fit the learners' needs and the real teaching situation. The amount of practice required to master the skill of writing in the genre of explanations should be considered.

- Description: Project implementation appears to be one the most difficult aspects of a manager’s job. The purpose of project management is to forecast or anticipate potential dangers and problems that may jeopardise the success of a project and then to plan, organise and control activities that will lead to the successful completion of projects in spite of all the envisaged risks. It is estimated that more than 80% of projects run late or over budget. Such failure often sinks small firms and erodes profits of larger organisations. Project implementation is therefore critical to the success of both small and big firms. The primary objective of this study is to improve project management in firms by investigating the variables that influence project implementation. More specifically, the study investigates the influence of organisational communication, leadership, business process management and resistance to change on project implementation. The sample consisted of 170 employees in a cross-section of industries. The sample was stratified to include senior managers, managers, supervisors and lower level employees. The empirical results show that organisational communication, participatory leadership, retention of the status quo and goal-oriented leadership increase project implementation, while resistance to change decreases project implementation.

- Description: Avusa Publishing (East Cape) (APEC) publishes several of the oldest and best known newspaper products in the Eastern Cape. The Eastern Province Herald is currently the oldest daily morning newspaper in South Africa and the average daily circulation of the paper is 25 000. Its main distribution is in the Nelson Mandela Bay Metropolitan area, as well as the area up to the Garden Route and as far East as Port Alfred. APEC also publishes the Weekend Post. According to the financial statements and circulation and advertisement figures of the company, the revenue generated by the company has not increased, but stayed stagnant. In addition to this, the daily circulation of the flagship publication, The Herald, has decreased from 29 000 in 2005 to 24 000 in 2008. As the company only generates revenue from two sources, namely advertising sales and the sale of newspapers, the above mentioned situation negatively affects the financial wellbeing of the company. The management dilemma that needed to be researched was how APEC's circulation and advertising income could be increased. The primary objective of this study was therefore to improve APEC's sales success by investigating the determinants of such sales success. More specifically, the study investigated the influence of determinants such as newsworthiness, value proposition, brand awareness, customer service, customer loyalty, credibility and new media on sales success, as measured by increased circulation and advertising revenue. Convenience sampling was used to select 287 employees working for the company. A mail survey was conducted among these 287 employees, but only 114 usable questionnaires were returned (a response rate of 40 percent). The empirical results revealed that brand awareness, customer loyalty and the use of new media technologies exerted a significantly positive influence on the sales success of APEC. The results further showed that newsworthiness, editorial credibility, value proposition and customer service exerted no significant influence on the APEC’s sales success. Despite the latter findings, the results revealed that there was a high level of trust and loyalty in the editorial content of APEC, as well as the perception of good value for money among both readers and advertisers. The managerial implications of these findings are discussed and areas of future research are recommended.

- Description: Helicobacter pylori classified as a class 1 carcinogen is a common human pathogen implicated in certain gastrointestinal diseases. Helicobacter pylori infection is acquired mainly in childhood, especially in developing countries. H. pylori infection causes peptic ulcer, duodenitis, gastritis and cancer. The growing resistance of H. pylori to antibiotics used in its treatment as well as other innate limitations of the triple therapy has necessitated a search for alternative treatment from natural sources which could be readily available, less cost effective. The antimicrobial activity of solvents (acetone, ethanol, methanol, chloroform and water) crude extracts of Lippia javanica were investigated against 31 H. pylori strains by the agar well diffusion technique. The minimum inhibitory concentration (MIC) was determined by spectrophotometric analysis at 620 nm using the broth micro dilution method and the rate of kill by broth dilution method. Phytochemical analysis was also performed. H. pylori standard strain NCTC 11638 was included as a positive control. Metronidazole and amoxicillin were used as positive control antibiotics. The ANOVA test was used to analyze the results using SPSS version 17.0. The strains were inhibited by all the extracts with inhibition zones of diameter ranging from 0-36 mm and 0-35 mm for the control antibiotic, clarithromycin. The MIC90 ranged from 0.039- 0.625 mg/mL for acetone; 0.039-1.25mg/mL for methanol, 0.00195-0.313 mg/mL for ethanol; 0.01975-2.5 mg/mL for metronidazole and 0.0048-2.5 mg/mL for amoxicillin. Acetone extract completely inhibited strain PE369C at MIC (0.1 mg/mL) and 2× MIC (0.2 mg/mL) in 18h and at ½× MIC (0.05 mg/mL) in 36h. Strain PE466C was completely inhibited at 4× MIC in 72h. Phytochemical analysis revealed the presence of flavonoids, saponins, tannins, steroids and alkaloids. The results indicate that the extracts of the leaves of L. javanica may contain compounds with anti-H. pylori activity and merits further study to identify the compounds.

Helicobacter pylori infection is acquired mainly in childhood, especially in developing countries. H. pylori infection causes peptic ulcer, duodenitis, gastritis and cancer. The growing resistance of H. pylori to antibiotics used in its treatment as well as other innate limitations of the triple therapy has necessitated a search for alternative treatment from natural sources which could be readily available, less cost effective. The antimicrobial activity of solvents (acetone, ethanol, methanol, chloroform and water) crude extracts of Lippia javanica were investigated against 31 H. pylori strains by the agar well diffusion technique. The minimum inhibitory concentration (MIC) was determined by spectrophotometric analysis at 620 nm using the broth micro dilution method and the rate of kill by broth dilution method. Phytochemical analysis was also performed. H. pylori standard strain NCTC 11638 was included as a positive control. Metronidazole and amoxicillin were used as positive control antibiotics. The ANOVA test was used to analyze the results using SPSS version 17.0. The strains were inhibited by all the extracts with inhibition zones of diameter ranging from 0-36 mm and 0-35 mm for the control antibiotic, clarithromycin. The MIC90 ranged from 0.039- 0.625 mg/mL for acetone; 0.039-1.25mg/mL for methanol, 0.00195-0.313 mg/mL for ethanol; 0.01975-2.5 mg/mL for metronidazole and 0.0048-2.5 mg/mL for amoxicillin. Acetone extract completely inhibited strain PE369C at MIC (0.1 mg/mL) and 2× MIC (0.2 mg/mL) in 18h and at ½× MIC (0.05 mg/mL) in 36h. Strain PE466C was completely inhibited at 4× MIC in 72h. Phytochemical analysis revealed the presence of flavonoids, saponins, tannins, steroids and alkaloids. The results indicate that the extracts of the leaves of L. javanica may contain compounds with anti-H. pylori activity and merits further study to identify the compounds.
