- Description: For integration between application-systems in a global context, interoperability needs to be established on a global level; global interoperability, in turn, is based on a global common application-interface. This is achieved through resolving differences in, inter alia, protocol profiles, among participants in the global network. ebXML is used as the point of departure. A messaging framework, which is based on existing Web technology and standards, is proposed. Certain security and Web service standards are examined to determine specific parameters for an interoperable secure messaging environment. A security based framework comprising a predefined message format and architecture is investigated for a secure interoperable global electronic marketspace.

- Description: Due to the continual constant battle women have to face in order to progress in the workplace, it has become necessary to assess the degree of transformational change within the workplace within South Africa to try to establish just what these barriers are and how it can be overcome. To examine the main problem, three sub-problems were identified. The first sub-problem that had been identified dealt with what the women’s rights in the new South Africa. It was investigated by evaluating the situation in the New South Africa and what has changed from the past. Is there more gender equality or not. The second sub-problem looked at the barriers that women face in the workplace. It is evident that sexual harassment, male chauvinism, trying to balance work and family as well as organisational structure and culture were among the top barriers that are a hindrance to women’s advancement in the workplace. Finally, the third sub-problem investigated what the glass ceiling effect is and the effect that this has on women in the workplace. The investigation evaluated, and emphasised the difficulties that women face in order to progress in the hierarchy of not only management but other occupations as well. Results have shown that most females and males believe that the glass ceiling is prevalent in the workplace. Most people believe that women can however break through the glass ceiling but now there is a new phenomenon, “The Glass Cliff” which allows women to break through the glass ceiling but only of organisations that are already in trouble.

- Description: After the first democratic elections in 1994, the Department of Education, through amendment of existing legislation and the adoption of new Acts, developed a new legal framework for the administration of education in the country. The effect of the change in education was not limited to the areas of the curriculum and staffing, but included a different approach to how schools will be governed and managed. In its efforts to democratise the country it was the intention of the government, through legislation, to devolve the powers of decisionmaking to the people. This study explored the phenomena that impact on the effective functioning of SGBs. The central phenomena identified were narrowed down to the role of the various stakeholders, their understanding of the functions of an SGB and the factors that hamper effective functioning. Furthermore, an exploration was made into the involvement of members of the SGB in the daily activities of the school. Research into the success of the second round of elections was conducted in 1999 by the Centre for Education Policy Development iv (CEPD). The Ministerial Review Committee on School Governance undertook research into the effectiveness of SGBs and issued a report of the study undertaken in 2004. Both these efforts were initiatives by the state. A phenomenological research approach was adopted for the purpose of the study. The rationale being that the researcher wanted to extract from the respondents their experiences as related during conversations. To lay the foundation for these interviews (conversations), a two-part questionnaire was developed. The first part of the questionnaire prompted the respondents to relate their experiences as members of the SGB. The second part elicited demographic and personal details from the respondents. The results of the study would be advantageous to various role players striving to improve the effectiveness of SGBs. The role players include all those involved at school level, the officials from the Education Management and Development Centre (EMDC), members of community-based and non-governmental organizations. The report would serve as a guideline for those individuals who are charged with the training and empowerment of SGBs.

- Description: Management’s response to shareholders’ return on investment as a priority occurs in an increasingly dynamic environment. Accompanying these activities is the need to realign responsibilities and to allocate scarce resources effectively. This is done in order to ensure that companies achieve global competitiveness and increase shareholders’ return on investment. Against this backdrop, local industry needs to find new methods or strategies in order to achieve world-class competitiveness, and to be able to access foreign investment. One way to achieve these goals is through Value Based Management (VBM). The objective of this study is to evaluate the strategic intent of Multinational Entities in applying VBM to increase shareholders’ return on investment. Based on the study, certain factors are critical to ensure the success of VBM. A postal survey to managers in the motor manufacturing and component manufacturing companies was conducted to check the managers’ familiarity with VBM, and their scope, and usage of VBM; and, based on the finding, to evaluate the impact of VBM on companies’ results. The empirical finding was compared with a literature review, and the following findings were made: There is a strong understanding and application of the VBM principle on the part of local entities with Foreign Direct Investment (FDI); Departmental performance is critical to an entity’s overall performance; Based on the study, 23 per cent of the respondents use Economic Value Added (EVA) as an internal reporting measure, and an average of 19 per cent use other metrics; A total of 89 per cent of respondents indicated that they strongly agree with the use of incentives for motivation. The above-mentioned points were covered by means of 4-M framework ― that is: Measurement, Management, Motivation, and Mindset.

- Description: The Eden District Municipality (EDM) is a local authority whose area of responsibility covers the Garden Route and also includes the Klein Karoo. The boundaries are from Storms River in the east, to Swellendam in the west and the Swartberg Mountains in the north. The EDM covers a very big area with seven big municipalities to consider and work with. Five of the municipalities, Langeberg, Mossel Bay, Knysna, George and Oudtshoorn have their own fire fighting services. The EDM fire fighting serves mainly the rural area. This is very costly due to the large distance required to travel to a fire, whereas the local municipalities are operating in their own towns. The new municipal boundaries include the rural areas, but the municipalities cannot service the rural areas because they do not as yet charge rates in the rural areas and therefore there is no revenue for the fire fighting service. They operate on the basis of verbal working agreements that make coordination of fire fighting very difficult. The fire fighting functions of the EDM as a category C municipality and the local municipalities as category B municipalities have been specified in the Municipal Structure Act. The allocation (division) of functions and powers relating to fire fighting service between the district municipality and local municipalities as determined by the Municipal Structure Act (Act 117 of 1998) has not been done. Due to the lack of invested capital, the resources are in a bad state. Some of the services have no capacity to attend to chemical fires or hazardous substance emergencies. Internationally, private fire fighting services can be contracted by government departments. These private fire fighting services are very large and the areas that they serve are extensive. These services have their own personnel structures functioning in an organisational structure that serves them well. These private services are very cost-effective and can therefore offer reasonable rates. Based on an investigation of various fire fighting services and different structures, the proposed structure for fire fighting in the EDM area will be a combination of structures. The diverse nature of the area will make the location of a sectoral structure and extension of its capacity difficult, and several factors that will impact on an new structure must be kept in mind. If all works well it will be relatively easy to achieve the five operations performance objectives envisaged for restructuring namely quality, speed, dependability, flexibility and cost.

An analysis of key factors responsible for and influencing the rate of employee absenteeism in the construction sector with specific reference to the Ngqura Harbour project

- Description: Absenteeism places huge financial burdens on organisations and has a detrimental effect on productivity. Aware of the direct and indirect costs associated with absenteeism, management must determine what factors are responsible for the absenteeism and how these factors can be rectified in order to reduce the rate of employee absenteeism in the organisation. The study’s main aims were firstly to determine which key factors are responsible for employees being absent from work and secondly, how they can be rectified in order to reduce absenteeism. From the data that was obtained from the literature study stress, substance abuse, lack of job commitment and organisational factors account for some reasons given for absenteeism. Employee absenteeism may also be partly due to not enough emphasis being placed on career development, staff retention and salaries. Other causes of absenteeism include personal responsibilities, lack of motivation and low morale in the workplace. Only recently have managers become aware of the true impact which alcohol and substance abuse have on organisations. More productivity is lost through on-the-job absenteeism than due to any other single factor. On-the-job absenteeism is difficult to define and very difficult to identify. Such absenteeism includes the presence of employees at work while they are sick but incapable of performing to their true capabilities – this often occurring on Mondays or Fridays or the day after payday. With current staff retention programs, mergers and joint ventures, organisations now demand the same level of production with fewer employees. This has given rise to an increase in the level of stress employees experience, which led to stress becoming a key factor responsible for absenteeism. When managing absenteeism the implementation of a proper measurement system is essential. This will enable the company to determine the extent of their absenteeism. An evaluation and comparison of these statistics over a period of time will also shed light on the nature of the absenteeism. These will result in the proactive handling of a company’s absenteeism. This is also the first step away from the acceptance of absenteeism and subsequently the nurturing of an absence culture. Employers can take a number of steps to reduce absenteeism, such as giving responsibility for absence management to senior or human resource managers rather than line managers, introducing return to work interviews, introducing discipline procedures and others. The great majority of absence management solutions completely overlook organisational factors, instead focusing on individual, claim processing and health-related factors in the quest to reduce lost productive days. Absence management programs should focus on organisational (not individual) drivers of absence to encourage a present and committed workforce. Absenteeism will never be eradicated, but through careful management organisations can reduce the absentee rate and the effect it has on the organization.

- Description: The harsh realities currently facing public hospitals such as budget cuts, understaffing and poor working conditions, have resulted in nurses experiencing low morale and finding it increasingly difficult to stay in the public health sector. The obvious targeting of South African nurses by recruitment agencies with job offers to work overseas is causing a massive skills’ drain that the country cannot afford. The situation is further compounded by the fact that the government is freezing posts of those nurses who have resigned. Consequently, nurses who are currently working in these hospitals have to cope with unreasonable workloads. Public hospitals are nowadays faced with the challenge of delivering quality health care within the constraints of gross staff shortages, and an increasingly competitive global health environment. The main objective of this study was to identify strategies that can be implemented by hospitals in order to reduce turnover, thereby enhancing retention of staff. Interviews were conducted with the matrons-in-charge of the hospitals under study to investigate strategies that are in place to improve retention. Secondary data regarding staff turnover in the hospitals under study was collected and analysed. It emerged that there are no concrete strategies in place to lower turnover. Hospitals are indeed experiencing staff turnover and posts that were vacated by those nurses that have resigned are frozen. The literature survey revealed three strategies that can be utilised to retain employees, namely, motivation strategies, effective leadership strategies and human resources strategies. Based on various literature reviews, it was concluded that the three strategies are interrelated. The empirical survey was conducted at the three selected hospitals, to determine the extent to which the retention strategies identified in the literature survey are being utilised. All three are invariably used in the hospitals. It is evident that the leadership behaviour in these hospitals affects the level of motivation of employees. The extent to which some of the human resources strategies are utilised invariably leads to low morale and dissatisfaction among employees. Lastly, research findings were assessed with the aim of drawing conclusions so that appropriate recommendations could be made. Recommendations focused on the retention strategies that can be implemented to boost morale of employees and enhance retention.

- Description: The aim of this research was to assess the recruitment and selection strategies used in the sales department of Old Mutual Group Schemes (OMGS) in the Eastern Cape. The company hopes to stem the high labour turn over in OMGS. After the Labour Relations Act 66 of 1995 (LRA) and Employment Equity Act 55 of 1998 (EEA) were promulgated, organisations in this country introduced new recruitment and selection policies. The challenge to most organisations is the implementation of these policies by managers. The requirements of these two legislations create problems for small companies because of the high costs involved especially in the implementation stages. The organisation incurs costs in the development of the new processes and the training of staff. Even after the new processes, labour turnover did not improve in OMGS. Senior management is trying any means possible to rectify the situation. The company policy was examined against the literature available and the recruitment and selection processes of different authors were investigated. The findings indicated that some steps in the recruitment and selection processes were not followed. It was recommended that the organisation use more recruitment sources to broaden the scope of accessing more suitable applicants.

- Description: The aim of this research was to assess the recruitment and selection strategies used in the sales department of Old Mutual Group Schemes (OMGS) in the Eastern Cape. The company hopes to stem the high labour turn over in OMGS. After the Labour Relations Act 66 of 1995 (LRA) and Employment Equity Act 55 of 1998 (EEA) were promulgated, organisations in this country introduced new recruitment and selection policies. The challenge to most organisations is the implementation of these policies by managers. The requirements of these two legislations create problems for small companies because of the high costs involved especially in the implementation stages. The organisation incurs costs in the development of the new processes and the training of staff. Even after the new processes, labour turnover did not improve in OMGS. Senior management is trying any means possible to rectify the situation. The company policy was examined against the literature available and the recruitment and selection processes of different authors were investigated. The findings indicated that some steps in the recruitment and selection processes were not followed. It was recommended that the organisation use more recruitment sources to broaden the scope of accessing more suitable applicants.

- Description: At present, the Eastern Cape is the only province in South Africa lacking a clinical hospital-based hyperbaric facility. East Cape Hyperbaric, to be situated at Greenacres Hospital in the Nelson Mandela Metropolitan, will offer the Eastern Cape community access to a world-class facility that will offer their patients Hyperbaric Oxygen Therapy and a Wound-Healing Facility. The objective of this study was to assess the viability of establishing a Hyperbaric Oxygen Therapy (HBOT) facility for the Nelson Mandela Metropolitan Municipality (NMMM), using sound business planning principles. A business plan precisely defines the business, identifies the goals, and serves as the firm's resume. A business plan will assist in allocating resources effectively, handle unforeseen complications, and assist in making sound business decisions. Because it provides specific and organized information about the company and how the company will repay borrowed money, a good business plan is a crucial part of business planning. In order to quantify the demand for a Hyperbaric Oxygen Therapy facility, a questionnaire was designed, in such a manner as to identify the current demand for a HBOT facility. The questionnaires were distributed to all medical practitioners within the NMMM by means of fax, e-mail and hand-delivery. Research conducted indicates that the results are promising enough to warrant the expedient creation of this business facility.

- Description: The purpose of this study was to develop a process model in order to meet outcomes of graduate training programmes, with specific relevance to Volkswagen of South Africa. To do this, VWSA’s Graduate Training Programme was assessed in terms of the approach currently used by VWSA to recruit, select and train graduate trainees. A literature study was conducted to reveal strategies for effectively training new recruits and the development of leadership competencies. Based on this study a model was developed to facilitate the graduate training programme process to achieve programme objectives. The study aimed at making a contribution to graduate training programmes by identifying key leadership competencies, as well as the training interventions which lead to the development of these competencies. It was found that the technical skills that the trainees acquire at their tertiary educational institutions are not sufficient in today’s workplace, thereby necessitating closer working relationships between these institutions and businesses so that needs can be shared, as well as more comprehensive training programmes being provided. The research methodology comprised the following steps: An analysis was made of VWSA’s current processes regarding recruitment, selection and training of their graduate trainees. iv An assessment of leadership competencies in terms of knowledge, skills and attitudes that contribute to successful performance was undertaken. Training interventions as a process was studied. An analysis was made as to what extent the existing training interventions for VWSA’s graduate programme achieve the desired programme outcomes by means of a research questionnaire circulated to mentors/coaches and graduate trainees within the organisation. A model was developed to serve as a holistic framework for the recruitment, selection and training of graduate trainees for all motor and related industries undertaking graduate training programmes. The above was achieved through a practical study and a literature study, making use of questionnaires, as well as relevant published, unpublished and electronic texts and studies. Conclusions were drawn and recommendations were made based on data established through theoretical research and data obtained from the questionnaires.

- Description: Metronidazole is a synthetic, nitroimidazole-derivative antibacterial and antiprotozoal agent (ed. McEvoy, 2001). It has been reported that crystallization occurs in aqueous suspensions of metronidazole benzoate, a bland-tasting prodrug of metronidazole, as a result of conversion from the anhydrous to the monohydrate form, thereby compromising the stability and clinical efficacy of the substance due to the particle size growth (Hoelgaard & Moller, 1983). A generic South African based pharmaceutical company commenced formulation of an aqueous metronidazole benzoate suspension and experienced problems with crystallization that occurred in products stored at 2 to 8 °C. This study aimed to continue development of the product in order to identify a formulation that prevents formation of the hydrate form of metronidazole benzoate and the accompanying crystal growth. A variety of metronidazole benzoate suspensions were manufactured on a laboratory scale using a number of natural and synthetic suspending agents, including magnesium aluminium silicate, povidone K90, xanthan gum and Avicel® RC-591 (microcrystalline cellulose and carboxymethylcellulose sodium), over a range of concentrations. Analytical quantification methods were developed and validated, and the physicochemical properties of the raw material and finished products were fully characterized. Rheological tests were performed in order to characterize the suspension flow properties. Real-time and accelerated stability studies and a temperature cycle study were conducted in accordance with the International Conference on Harmonization (ICH) guidelines. Conversion of metronidazole benzoate to the monohydrate form took place in suspensions containing xanthan gum 0.65 percent m/v under real-time and accelerated storage conditions. The suspensions containing Avicel® RC-591 were found to be physically and chemically stable after the temperature cycle and over the 12-week period whilst stored at 25 ºC / 60 percent RH and 5 ºC. The suspensions were chemically stable whilst stored at 40 ºC / 75 percent RH but showed sedimentation at this accelerated condition. The metronidazole benzoate contained in these products remained in the anhydrous state under all storage conditions and were consequently concluded to be the most stable formulations out of all the products analyzed in the current study. The suspending agent system consisting of microcrystalline cellulose and carboxymethylcellulose sodium thus shows promise in preventing the conversion of metronidazole benzoate from the anhydrate to the monohydrate form, thereby inhibited the subsequent increase in particle size due to crystal growth.

- Description: Traditional medicine has a long history of being used for treating various ailments ranging in severity. Although traditional medicine has typically been the health care for the poorest levels of society, there is a worldwide growth in popularity. The growing popularity of traditional medicine, termed the green boom, may be ascribed to people taking a more holistic approach to maintain their health. Traditional medicine is widely used on a regular basis by 70% of South Africans. Various indigenous medicinal plants are used for the preparation of traditional herbal medicine. These plants are mostly indigenous to the regions were it is used. In this study four medicinal plants (Bulbine frutescens, Leonotis leounurus, Melianthus major & Zantedecshia aethiopica) that are traditionally used in the Eastern Cape region for treating burn wound infections, were collected for investigation. The in vitro antibacterial activity of these plants was tested against different bacterial strains of eight different bacteria. The bacteria used in this investigation included bacterial strains of four Gram-positive bacteria, S. aureus, methicillin-resistant S. aureus (MRSA), E. feacalis, S. pyogenes and four Gramnegative bacteria, P. aeruginosa, A. baumanii, K. pneumoniae and P. mirabilis. Traditional preparations as well as three different extracts (methanol, aqueous & acetone) of the plants were used for in vitro antibacterial activity testing. The microtitre plate assay and agar dilution assay were used for determining the antibacterial activity of the traditional preparations and plant extracts against the different bacterial strains. In the microtitre plate assay the antibacterial activity was tested using the bacterial growth indicator, INT and a microtitre plate spectrophotometer to determine the minimal inhibitory concentrations of the plant extracts and traditional preparations. The microtitre plate assay was used for testing the antibacterial activity of the plants against the bacterial strains of five bacteria, S. aureus, MRSA, P. aeruginosa, A. baumanii and K. pneumoniae. The bacterial strains of the three bacteria, S. pyogenes, E. feacalis and P. mirabilis were not compatible with the microtitre plate assay using INT and spectrophotometric readings to determine bacterial inhibition. Therefore the agar dilution assay were used as an alternative method for determining the MIC’s of the plant extracts against the bacterial strains of these bacteria. The initial plant extract concentration in the microtitre plate assay differed with the different plant extracts in the microtitre plate assay. Acetone followed by methanol extracted the highest plant extract concentrations with the different medicinal plants. M. major followed by L. leonurus produced the highest plant extract concentrations following extraction with the different extraction solvents. Consequently the acetone extract of M. major had the highest plant extract concentration before serial dilution in the microtitre plate assay. Uniform plant extract concentrations were tested in the agar dilution assay. The methanol extract followed by the acetone extract of the plants gave the highest antibacterial activity against the different bacterial strains. The extracts of M. major followed by L. leonurus inhibited the highest number of bacterial strains in the microtitre plate assay and the extracts of B. frutescens inhibited the lowest number of bacterial strains. The acetone and methanol extracts of M. major were the only extracts that displayed antibacterial activity in the agar dilution assay. The bacterial strains of P. mirabilis were the only bacteria that were inhibited using this method. The bacterial strains of S. pyogenes and E. feacalis were not inhibited at any of the plant extract concentrations in the agar dilution assay.

- Description: This paper reviews the literature on innovation in order to build an agenda for an investigation into the extent to which Metropolitan Retail, within Metropolitan Life Pty in South Africa, focuses on technology innovation capabilities and perspectives. The research was conducted in the areas of, technology innovation capabilities, perspectives guiding the business strategy to integrate and accelerate innovation and contextual aspects influencing innovation perspectives. The extent of focus by the firm on capabilities and perspectives was measured. Data gathered was disseminated and processed by means of Microsoft Excel spreadsheets. The results on current focus indicate that the firm’s focus is mostly on improving core business, although the extent is less than adequate. In other words, generate incremental innovations that can be developed and implemented rapidly and inexpensively. This approach of implementing innovation is in line with the business strategy, more specifically, with the objective of reducing costs and making profits. The findings of the research further suggest that the firm should consider focusing mostly on exploiting strategic advantages. In many firms the fundamental emphasis on technology innovation in developing products, processes and services is thought to determine their ability to cope with never ending customer demands and competitive practices. Coupled with this thought is a reality of high failure rate of technology innovation projects. Against this backdrop, general managers are faced with strategic innovation options, which can make or break firms. Changes in the economic and government environments influence the innovation approach of the firm most. These changes have undoubtedly presented firms with opportunities as well as risks. Possibly the greatest challenge confronting general managers in this context is the building of critical capabilities to enhance the firm’s agility. This challenge presents opportunity for further research.

- Description: The purpose of this study is to investigate specific contributing factors affecting quality assurance in the diagnosis of conventional cervical smears. More than half of South- African women fail to have one cervical smear in their lifetime and +/- 50 percent of those who do have cervical smears taken, are lost to follow-up. Since cervical cancer is the most common malignancy amongst women in developing countries, the medical profession will have to endeavor to screen a higher rate of women and ensure a 100 percent quality assurance with every patient treated in order to reduce the unacceptable high incidence of cervical carcinoma. At this stage it seems like an impossible task to screen all women in South Africa, due to far-off rural areas, shortage of medical professionals and the lack of knowledge of some women of the necessity of cervical smears. Many newly qualified South-African doctors leave the country to go and work elsewhere. South Africa then in turn has to recruit doctors from other countries to staff the State hospitals and clinics. Some areas have one doctor to thousands of patients, insufficient nursing personnel and inadequate equipment. Doctors in some areas cannot cope with the volume of work and the long hours. One has to accept that the quality of the management of some patients is affected negatively. There are a number of medico-legal issues (world wide) in relation to aspects of cervical cancer prevention practices which are controversial and are of particular concern to all of those involved in cervical cancer prevention. Various countries have therefore formed different national organizations to address the medico-legal issues in screening for the prevention of cancer. These organizations monitors procedures, internal quality control as well as external quality control. In South Africa, medico-legal cases are not so prevalent, but may become so shortly. The South-African medical professionals therefore have to ensure that their quality of work conforms to accepted good practice in all circumstances. State hospitals serve thousands of patients per month and it is an every day occurrence to see long queues of patients sitting waiting for doctors and who often have to come back the following day. The situation appears to be much improved in private practice and since patients have medical cover and accessible medical facilities. Since cervical cancer is the most common malignancy amongst women in developing countries, the medical profession will have to endeavor to screen a higher rate of women and ensure a 100 percent quality assurance with every patient treated in order to reduce the unacceptable high incidence of cervical carcinoma. At this stage it seems like an impossible task to screen 100 percent of women in South Africa, due to far-off rural areas, the shortage of medical professionals and ignorance of patients. Quality assurance is therefore of paramount importance to every medical professional for every patient treated. Laboratories all worldwide have been, or are in the process of being accredited by their specific accreditation authorities. The main reason for this is improvement of quality control and therefore quality assurance. The South African National Accreditation Society (SANAS) now accredits various laboratories in South Africa with the view of accreditting all laboratories within a certain time limit. The Ampath laboratory Port Elizabeth was successfully accredited during 2001. Accredited laboratories have to uphold a very high degree of quality to remain accredited. A team of professionals inspects the laboratory every 2 years and other quality assurance staff inspects the laboratories every few months. All aspects of the laboratory are checked, e.g. the qualification of staff, their registration with the Health Professions Council of South Africa (HPCSA), their curriculum vitaes, equipment, safety of the laboratory etc. Since the laboratory chosen for this study, is accredited, the author evaluated every cervical smear that was received in the laboratory since the year 2000, with the following objectives in mind: · Whether the presence or absence of an endocervical component has an effect on the adequacy of cervical smears · To determine the effect of using smaller coverslips on quality assurance in the cytology laboratory · Evaluate the effect that manual re-screening of smears has on quality assurance in the cytology laboratory. As there is a shortage of cytotechnologists and pathologists worldwide, several countries make use of automated screening devices as primary screening or secondary screening for quality assurance. These devices were tested in some laboratories in South Africa but were found to be very expensive and sensitivity and specificity were not up to standard. Sensitivity is a measure of the ability of a test to detect the abnormal - Sensitivity is the ratio of true positives to true positives + false negatives. Specificity is a measure of the ability of a test to correctly identify the negative - Specificity is the ratio of true negative to true negatives + false positives. The automated screening machines failed to identify abnormal cells amongst inflammatory cells, as well as in very blood stained smears. Several other problems also occurred and an increasing number of smears had to be manually rescreened, thus making this exercise costly and not helpful as a quality assurance instrument. The slides used for this thesis, have been retrieved from the archives of the Ampath laboratory in Port Elizabeth. Fourteen specific contributing factors affecting quality assurance in the diagnosis of cervical smears are also discussed and conclusions and recommendations given.

State hospitals serve thousands of patients per month and it is an every day occurrence to see long queues of patients sitting waiting for doctors and who often have to come back the following day. The situation appears to be much improved in private practice and since patients have medical cover and accessible medical facilities. Since cervical cancer is the most common malignancy amongst women in developing countries, the medical profession will have to endeavor to screen a higher rate of women and ensure a 100 percent quality assurance with every patient treated in order to reduce the unacceptable high incidence of cervical carcinoma. At this stage it seems like an impossible task to screen 100 percent of women in South Africa, due to far-off rural areas, the shortage of medical professionals and ignorance of patients. Quality assurance is therefore of paramount importance to every medical professional for every patient treated. Laboratories all worldwide have been, or are in the process of being accredited by their specific accreditation authorities. The main reason for this is improvement of quality control and therefore quality assurance. The South African National Accreditation Society (SANAS) now accredits various laboratories in South Africa with the view of accreditting all laboratories within a certain time limit. The Ampath laboratory Port Elizabeth was successfully accredited during 2001. Accredited laboratories have to uphold a very high degree of quality to remain accredited. A team of professionals inspects the laboratory every 2 years and other quality assurance staff inspects the laboratories every few months. All aspects of the laboratory are checked, e.g. the qualification of staff, their registration with the Health Professions Council of South Africa (HPCSA), their curriculum vitaes, equipment, safety of the laboratory etc. Since the laboratory chosen for this study, is accredited, the author evaluated every cervical smear that was received in the laboratory since the year 2000, with the following objectives in mind: · Whether the presence or absence of an endocervical component has an effect on the adequacy of cervical smears · To determine the effect of using smaller coverslips on quality assurance in the cytology laboratory · Evaluate the effect that manual re-screening of smears has on quality assurance in the cytology laboratory. As there is a shortage of cytotechnologists and pathologists worldwide, several countries make use of automated screening devices as primary screening or secondary screening for quality assurance. These devices were tested in some laboratories in South Africa but were found to be very expensive and sensitivity and specificity were not up to standard. Sensitivity is a measure of the ability of a test to detect the abnormal - Sensitivity is the ratio of true positives to true positives + false negatives. Specificity is a measure of the ability of a test to correctly identify the negative - Specificity is the ratio of true negative to true negatives + false positives. The automated screening machines failed to identify abnormal cells amongst inflammatory cells, as well as in very blood stained smears. Several other problems also occurred and an increasing number of smears had to be manually rescreened, thus making this exercise costly and not helpful as a quality assurance instrument. The slides used for this thesis, have been retrieved from the archives of the Ampath laboratory in Port Elizabeth. Fourteen specific contributing factors affecting quality assurance in the diagnosis of cervical smears are also discussed and conclusions and recommendations given.

- Description: The growth of the Chinese economy represents a significant opportunity for global travel and tourism and it has raised the expectation that the South African tourism industry will explore and benefit from the Chinese outbound market growth. Since international travel and tourism is becoming a significant component of the South African economy, it is important to understand the factors that influence consumer decision-making in tourism. The main objective of this study was to determine the factors that influence the decision-making of Chinese tourists that travel to South Africa. The research gives a systemic review of the Chinese outbound market, starting with the Chinese outbound travel history, and the impact of the social-economic issues on Chinese travel and tourism. An overview is provided of the size, growth and the regulation of the Chinese outbound market, as well as the main characteristics of Chinese outbound tourists. The factors that influence decision-making are compartmentalised into two categories: internal and external factors. Internal and external factors relate to the concept that people travel due to the fact that they are pushed by their own internal forces and pulled by the external forces such as the social environment, reference groups, social class, the restrictions from government regulations and the attraction of travel destination countries. The empirical findings reflect that the factors that have the most significant impact on the decision-making process of Chinese outbound tourists travelling to South Africa are perception about safety, lack of knowledge about South Africa and a growth in the use of the Internet as a source of tourist information. The study also reflects a tendency towards individualism and a shift away from traditional group decision-making. Based on the findings of the empirical study, South Africa tourism needs to offer a safe travel environment, provide greater access to information featuring South Africa as a tourist destination, and offer discounted travel packages

- Description: Background: Higher Education (HE), through HE Institutions, plays a very important role in society. There is thus a need for this sector to be well managed, especially with regards to planning, organising, and controlling. Corporate Governance has received a lot of attention in recent times, especially to engender trust on the part of the stakeholders. There are many similarities, but also significant differences in the governance of HE institutions and public companies. Information Technology (IT) plays an extremely important role in the modern organisation, creating huge opportunities, but also increasing the risk to the organisation. Therefore, effective governance of IT in HE Institutions is of great importance.

Aspects of expert evidence in the criminal justice system

- Type: Thesis , Masters , LLM

- Description: The rule excluding evidence of opinion is traditionally stated in broad and general terms, subject to a more or less closed list of exemptions. Stephen says that a witness’s opinion is “deemed to be irrelevant”. A witness may depose to the facts which he has observed, but he may not ordinarily state any inferences which he has drawn from those facts, or opinions founded upon facts of which he has no personal knowledge. The general rule is that the evidence of opinion or belief of a witness is irrelevant because it is the function of a court to draw inferences and form its opinion from the facts; the witnesses give evidence as to the facts and the court forms its opinion from those facts. The opinion of an expert is admissible if it is relevant. It will be relevant if the witness’s skill, training or experience enables him materially to assist the court on matters in which the court itself does not usually have the necessary knowledge to decide. Where the topic is such that an ordinary judicial officer could be expected to be able, unassisted, to draw an inference, expert evidence is superfluous. In principle, there is no rule that a witness cannot give his opinion on an issue that the court has to decide ultimately. It is not experts alone who may give their opinions on ultimate issues but, in practice, there is a strong tendency to regard the evidence of lay persons on ultimate issues as constituting prima facie evidence only. If such lay testimony remains unchallenged, it may be of greater significance. It is generally true that relevant evidence is admissible and irrelevant evidence is inadmissible. At this stage the following question may be posed: is the opinion of any witness – whether from an expert or lay person – admissible evidence? Should an opinion be admitted for purposes of persuading the court to rely on it in deciding the issue at hand? The basic answer is that relevance remains the fundamental test for admissibility. Certain issues simply cannot be decided without expert guidance. Expert opinion evidence is therefore readily received on issues relating to ballistics, engineering, chemistry, medicine, accounting and psychiatry, to mention only a few examples. The problem which arises is this: what is the best way of cross-examining the expert witness? Although the concept of skilful cross-examination conjures up the image of the crossexaminer destroying the expert witness in the witness box, total annihilation of expert evidence in court occurs only rarely. In reality, lawyers who are expected to cross-examine experts are often at a disadvantage in that they do not possess sufficient in-depth knowledge of the specific field of expertise to enable them to cross-examine the witness. Despite the expert nature of the evidence, it is suggested that the true basis of crossexamination should not be abandoned when dealing with experts. The effectiveness of crossexamination is enhanced by keeping the number of questions to a minimum as well as opening and concluding with good strong points. At the outset it should be mentioned that there is a distinction between matters of scientific fact and matters of mere opinion. On matters of scientific fact experts seldom differ but within the province of opinion one encounters difficulties. Lengthy cross-examination concerning expert’s theoretical knowledge is usually inefficient and should rarely be attempted. Cross-examination should be directed at pure logic or scientific analysis. The cross-examiner should always have relevant authority with him in court so as to confront the expert with these. The whole effect of the testimony of an expert witness can also be destroyed by putting the witness to test at the trial as to his qualifications, his experience and his ability and discriminations as an expert. A failure to meet this test renders his evidence nugatory.

- Description: The research problem in this study was to look at barriers confronting small and micro tourism enterprises of the previously disadvantaged entrepreneurs in the Nelson Mandela Metropole. To achieve this objective, literature on the barriers confronting these enterprises, was reviewed. The empirical results obtained indicate a strong concurrence with the literature study emphasizing the importance of the barriers identified and the possible ways of resolving them. The main problems identified in the literature review were: lack of institutional support, legislation, lack of access to finance, and lack of entrepreneurial skill (planning and organizing, marketing, training and human resources, time management, conflict resolution and negotiation skill). These barriers identified in the literature study were then used to develop a questionnaire to test the extent to which small and micro tourism enterprises are constrained by barriers when starting up and how these barriers can be resolved. A sample of 18 small and micro tourism businesses was taken, one from Uitenhage and 17 from Port Elizabeth. The main results were that there are few small and micro tourism businesses of the previously disadvantaged entrepreneurs in the Nelson Mandela Metropole. The main reason for this is that previously disadvantaged entrepreneurs are not given adequate support by government institutions created for that purpose. iv Most of these businesses are not getting enough financial support during start-up because of problems with the owners’ credit records. The results also indicate that small and micro tourism businesses of the previously disadvantaged entrepreneurs view legislation intended to develop them, as actually stifling their development, such as the municipal credit laws. The study recommends that more institutional support should be given to small and micro tourism businesses that are starting up, and government institutions responsible for the development of small and micro businesses need to target the previously disadvantaged communities with their marketing. The Nelson Mandela Metropolitan Municipality and the Small Enterprise Development Agency (SEDA) need to conduct research on alternative non-collateral financing for small and micro businesses. More training programmes on business skills have also to be conducted.

- Description: To ensure a long-term successful product brand, it is important to build brand awareness, to reach the consumer’s mind, encourage a consumer to develop a preference and eventually provide a positive contribution to consumer decision-making. Therefore, there is a need to understand and identify the role of brand awareness in the purchase process. An understanding of students as consumers and their brand awareness is important to marketers, particularly as students are recognised as a specialised market segment for a variety of products. The research focused on identifying the differences, if any, in brand awareness and its role in students’ purchase of sportswear clothing and sportswear shoes (high-involvement products) and coffee (a low-involvement product). A drop-off survey was used to collect the required empirical data from a convenience sample of 450 students enrolled at the Nelson Mandela Metropolitan University. The empirical findings showed that students were more aware of sportswear clothing and shoe brands than of coffee brands. Advertising played an important role in the awareness of sportswear shoes and clothing brands, but seemed unimportant in the case of coffee. Brand elements were found to enhance brand awareness. The brand name was important for coffee, while the name and the logo played a role in students’ awareness of sportswear brands. The study deduced that differences in brand awareness between high-involvement and low-involvement products exist among the students. Marketers thus need to choose appropriate strategies to create and increase brand awareness for the different products.

- Description: As argued by authors like Franzen on whose work the greater part of the introduction, the main problem and sub-problem has been based, the objective of this study was to establish the extent to which the performance evaluation system currently in use at the subject Institution conforms to the benchmark performance management systems as espoused in literature. Further, the objective was to establish the differences and commonalities between the performance management systems practiced in the corporate sector and current practice at the subject Institution. Best practice was thus lifted to form part of the recommendation of this study. A questionaire was designed based on the guidelines in the literature study in order to determine how the subject Institution conducts its performance appraisal and how this relates to the four general purposes of performance management mentioned in the study. The respondents' opinion obtained from the questionaire were compared with the guidelines in literature and clustered around the four identifiable general purposes of performance management. The study concludes with a statement of current practice at the subject Institution, and outlines the extent of conformance to benchmark practice on performance management systems. Recommendations are made based on best practice and direction is given to future research into contemporary practices with the express aim of enhancing quality in higher education applying the quality-related procedures of industry and commerce, where quality is crucial to success (Winch, 1996: 9-13). The current performance management system at the subject Institution proves to be largely conforming to the benchmark. However it should require comments made by the respondents that pertain to improvement.
