- Description: The Chinese inbound tourism market to SA has been acknowledged as an emerging market. However, South African tour operators experience difficulties in establishing and developing viable partner relationships with Chinese travel agents. Recognizing the size, importance and complexity of this market, the major purpose of this research is to explore and investigate the crucial process of developing Sino-South African partnership relationships in the tourism industry, to facilitate the establishment of business relationships with Chinese travel agents. This study is draws on applied marketing, management and cross-cultural theories on networking to explore the process of developing partnership relationships in the Chinese inbound tourism market to SA. The literature on networking, the development of networking relationships, and the effect of guanxi (connection), a key feature of Chinese business networking on partnership relations are reviewed. Given the limited research conducted on this topic and its cross-country nature, a quantitative research method was adopted for this study. Specifically, this study utilized e-mail survey techniques to explore the relationships between South African inbound tour operators and Chinese travel agents. This study identifies that the process of developing partnership relationships between Chinese travel agents and South African inbound tour operators is culturally embedded. They are giving rise to communication problems that affect partnership relationships. A new stage model of the development of partnership relationships between South African inbound tour operators and Chinese travel agents is therefore developed. In particular, the study identifies important factors in the process of developing business relationships. For example, mutual commitment, the pricing issue, word-of-mouth, and quality of services are all considered crucial in attaining long-term stable partnership relationships. Guanxi plays a significant, but not decisive role in the process of developing partnership relationships between Chinese travel agents and South African inbound tour operators. However, guanxi relationships can provide added value to the partnership relationships.

- Description: Employee empowerment is a strategy that small business managers can deploy to add value to the business. This strategy is aimed at cultivating the power and ability of employees in their jobs. A business is a business by people working in it though they differ in many ways their contribution to the success of the organization is very important. However, these people are not often recognized as value contributors in the success of the business and for this reason they do not intend to add value to the business and they become demotivated to do their jobs properly. People are the business storehouse of knowledge and they are central to the organization's competitive advantage. Well educated, coached, and highly motivated people are critical to the development and execution of strategies, especially in today's fast-paced market, where top management can no longer assure the business competitiveness in isolation. In the business world, almost all businesses are doing the same, small businesses should strive to do things differently, and the only way that they can achieve that uniqueness is through instilling frankness and liberty to employees so that they act as if the business also belongs to them. The reason behind this success is the strategy the business is using to get into the heart of its customers, and this strategy is “employee empowerment”. People are the business's most underutilized resource; involvement in an organization is no longer a one-way road. In today's corporate environment a manager must work towards engaging the organization forcefully enough to achieve its objectives. New knowledge-based enterprises are characterized by flat hierarchical structures and a multi-skilled workforce. Managers assume more leadership and coaching tasks and work hard to provide employees with resources and working conditions they need to accomplish the goals they have agreed to. In brief, managers work for their staff, and not the reverse and this makes employees feel valued. Small business owners should tap into a new dimension of utilizing employee empowerment strategies in their businesses as these are proficient and are not costly. This paper investigates employee empowerment strategies that can be used by small, medium and micro enterprises (SMME's). An important reason for this investigation is that small businesses have incompetent skilled labour force due to the fact that they operate under a limited budget from which it would be difficult to get skilled workers who will demand higher salaries, as a result they need to put their energies rather on equipping and educating their employees through empowerment, which could at the end make them feel valued and part of the business. It is imperative to firstly assess the current situation of small business commitment to employee empowerment strategies; to what extent do they use employee empowerment strategies in their businesses In terms of the empirical study it was determined that small businesses were not aware of the concept of employee empowerment, but are in actual fact practicing employee empowerment strategies that have been theoretically revealed, according to the researcher’s observation, they were not aware of the impact of employee empowerment in the organization and that they can be implemented into the business. Therefore, by introducing the concept of employee empowerment and the strategies that can be used in small businesses, SMME's can enhance their services to customers, increase productivity and contribute to the welfare of employees to add value to the individual, the business and the country.

- Description: Each individual/household progresses through the family life cycle (FLC). This progression, which is characterized by various stages and varying consumption portfolios, can be traditional or non-traditional in nature. In the general marketing sense, the FLC concept has great value. The concept is utilized in a variety of marketing activities, particularly in segmentation, and is also applied in consumer behaviour. The lack of research regarding the FLC in South Africa and the need to investigate the concept’s applicability to different environments motivated this research. The aim of the study was to determine how the FLC within a South African context compared to the theoretical depiction of the concept. The evaluation of literature revealed five distinct traditional stages and an array of non-traditional stages, determined by a combination of life stage determining variables. Regarding the empirical approach, self-administered questionnaires were distributed to a convenience sample consisting of 225 students and staff members of the then Port Elizabeth Technikon. The empirical findings revealed the following. {u100083} Non-traditional stages were more prevalent than traditional stages. ii {u100083} Marital status, the presence/absence of children and living arrangement appear to be sufficient life stage determining variables for both current and prospective life stage classifications. {u100083} The consumption portfolios of individuals in the traditional FLC were similar to theory. The research provided insight into the consumption portfolios of individuals in the non-traditional FLC. {u100083} Based on the intentions of certain individuals regarding marriage, having children and living arrangements, it appears as though the future FLC will include an integration of traditional and non-traditional progressions.

- Description: Information Security is currently viewed from a technical point of view only. Some authors believe that Information Security is a process that involves more than merely Risk Management at the department level, as it is also a strategic and potentially legal issue. Hence, there is a need to elevate the importance of Information Security to a governance level through Information Security Governance and propose a framework to help guide the Board of Directors in their Information Security Governance efforts. IT is a major facilitator of organizational business processes and these processes manipulate and transmit sensitive customer and financial information. IT, which involves major risks, may threaten the security if corporate information assets. Therefore, IT requires attention at board level to ensure that technology-related information risks are within an organization’s accepted risk appetite. However, IT issues are a neglected topic at board level and this could bring about enronesque disasters. Therefore, there is a need for the Board of Directors to direct and control IT-related risks effectively to reduce the potential for Information Security breaches and bring about a stronger system of internal control. The IT Oversight Committee is a proven means of achieving this, and this study further motivates the necessity for such a committee to solidify an organization’s Information Security posture among other IT-related issues.

- Description: Today, information is considered a commodity and no enterprise can operate without it. Indeed, the information and the supporting technology are pivotal in all enterprises. However, a major problem being experienced in the business environment is that enterprise risk cannot be managed effectively because business and information-related risk are not congruently aligned with risk management terminology and practices. The business environment and information technology are bound together by information. For this reason, it is imperative that risk management is synergised in the business, ICT (Information and Communication Technology) and information environments. A thorough, all inclusive, risk analysis exercise needs to be conducted in business and supporting environments in order to develop an effective internal control system. Such an internal control system should reduce the exposure of risk and aid the safeguarding of assets. Indeed, in today’s so-called information age, where business processes integrate the business and ICT environments, it is imperative that a unary internal control system be established, based on a holistic risk management exercise. To ensure that the enterprise, information and ICT environments operate free of the risks that threaten them, the risks should be properly governed. A model, EPiRISMM (Enterprise Information Risk Management Model) is proposed that offers to combine risk management practices from an ICT, information, governance, and enterprise perspective because there are so many overlapping aspects inherent in them. EPiRISMM combines various well-known standards and frameworks into one coherent model. By employing EPiRISMM, an enterprise will be able to eliminate the traditional segmented approach of the ICT department and thus eliminate any previous discontinuity in risk management practices.

- Description: The failure to evaluate the service quality by comparing service expectations and service perceptions of students requires that the management of NMMU libraries identify the service expectations and service perceptions of students and measure the gaps between these service expectations and service perceptions of students. A literature review was conducted to explore the service expectations and service perceptions of students. An effective method (using the LibQUAL model) to evaluate the service quality of NMMU libraries based on the service expectations of students was described. Thereafter, a LibQUAL survey was used to collect the required empirical data from a convenience sample of 2 047 students enrolled at NMMU. The empirical findings showed that gaps existed between the service expectations and service perceptions of students at different campuses of NMMU. At different campuses of NMMU, the service expectations of students were not met in term of the service perceptions of the four dimensions (affect of service, library as place, information access and personal control) of the LibQUAL model. ii The study identified the gaps between the service expectations and service perceptions of students at different NMMU campuses and conclusions and recommendations based on these gaps were formulated. The management of the NMMU libraries needs to choose appropriate strategies to improve the quality of NMMU library services based on the service expectations of students.

- Description: Quartz fields contribute significantly to plant diversity in the Succulent Karoo biome. They are distinctly different from surrounding habitats and have high levels of plant endemism. Biological soil crusts are features of quartz field soils and fulfill a vital function in that they stabilize soils. It is important for managers of nature reserves and agricultural rangelands to know what factors influence quartz field soils and vegetation. Both stakeholders could benefit from new information that would allow for informed decision-making regarding land-use on quartz fields. The present study took place in the Namaqua National Park that contains a significant proportion of the Riethuis-Wallekraal quartz fields phytochorion. The first part of the study aimed to understand whether certain land-use activities potentially destabilize quartz field soils, which might have possible ramifications for associated biological soil crusts and vegetation. It was followed by relating variation in soil stability with species richness, cover and species composition of quartz field vegetation. Overall, positions assumed to be impacted by land-use activities had less stable soils compared to positions assumed not be impacted. Soil stability had a significant influence on species richness and cover but to a lesser degree on species composition. Quartz field vegetation was significantly influenced by soil physical and chemical properties as well as location in the quartz fields landscape. The second part of the study aimed at understanding how species richness of isolated quartz outcrops is related to their size compared to that of a mainland body of quartz outcrops. No clear species-area relationships emerged from the study. There were significant differences between isolated outcrops and mainland outcrops in substrate and vegetation composition. Findings are discussed in relation to Island Biogeography Theory.

- Description: Instant Messaging (IM) has grown tremendously over the last few years. Even though IM was originally developed as a social chat system, it has found a place in many companies, where it is being used as an essential business tool. However, many businesses rely on free IM and have not implemented a secure corporate IM solution. Most free IM clients were never intended for use in the workplace and, therefore, lack strong security features and administrative control. Consequently, free IM clients can provide attackers with an entry point for malicious code in an organization’s network that can ultimately lead to a company’s information assets being compromised. Therefore, even though free IM allows for better collaboration in the workplace, it comes at a cost, as the title of this dissertation suggests. This dissertation sets out to answer the question of how free IM can facilitate an attack on a company’s information assets. To answer the research question, the dissertation defines an IM attack model that models the ways in which an information system can be attacked when free IM is used within an organization. The IM attack model was created by categorising IM threats using the STRIDE threat classification scheme. The attacks that realize the categorised threats were then modelled using attack trees as the chosen attack modelling tool. Attack trees were chosen because of their ability to model the sequence of attacker actions during an attack. The author defined an enhanced graphical notation that was adopted for the attack trees used to create the IM attack model. The enhanced attack tree notation extends traditional attack trees to allow nodes in the trees to be of different classes and, therefore, allows attack trees to convey more information. During the process of defining the IM attack model, a number of experiments were conducted where IM vulnerabilities were exploited. Thereafter, a case study was constructed to document a simulated attack on an information system that involves the exploitation of IM vulnerabilities. The case study demonstrates how an attacker’s attack path relates to the IM attack model in a practical scenario. The IM attack model provides insight into how IM can facilitate an attack on a company’s information assets. The creation of the attack model for free IM lead to several realizations. The IM attack model revealed that even though the use of free IM clients may seem harmless, such IM clients can facilitate an attack on a company’s information assets. Furthermore, certain IM vulnerabilities may not pose a great risk by themselves, but when combined with the exploitation of other vulnerabilities, a much greater threat can be realized. These realizations hold true to what French playwright Jean Anouilh once said: “What you get free costs too much”.

- Description: The South African ostrich industry is presently characterised by a drastic decline in the slaughter price of slaughter birds, due to the drop in the price of meat as well as leather. As a result, the economic viability of ostrich farming is severely hampered by these developments, and many generally accepted industry practices have to be reviewed. Among the practices under review is the possibility of slaughtering ostriches at an earlier age than the traditional slaughter age of 12 - 14 months, in order to minimise feed costs and the incidence of damage to the skin. However, little information is available on the effect of the slaughter age on the yield and quality of the economically important end-products. The effect of slaughter age on production and the economic viability of a commercially intensive ostrich production system was consequently evaluated in a completely randomised experimental design involving two batches (n= 81 and n= 94) of ostriches. The experiments took place at Kromme Rhee experimental farm of the Elsenburg Research Centre near Stellenbosch. The birds were subject to experimental treatment at the age of 4 months (n= 81, from May 2004 to March 2005) and 6 months (n= 94, from August 2004 to August 2005) respectively. The ostriches were randomly divided into 10 groups of between 16 and 20 birds per group. Standard production practices, as applied in an intensive ostrich production unit, were implemented. Clean drinking water and self-mixed grower diet (min 15 percent crude protein, 0.68 percent lysine and 11.4 MJ ME per kg feed) and finisher diet (min 14 percent crude protein, 0.55 percent lysine and 9.8 MJ ME per kg feed) were provided ad libitum to the birds. Birds were slaughtered at the ages of 8.5, 10.5, 12.5, 14.5, and 16.5 months respectively. Data on feed intake and yields of cold carcass, crust skin size, skin grade and total feathers was recorded for birds slaughtered at the respective ages. Data was analysed according to the analysis of variances. Values for meat yield, skin size yield and feed intake were predicted by regression analysis based on experimental values. Industry figures and norms were used as proxy for other production inputs and costs. A gross margin type analysis was performed to evaluate the effect of different slaughter ages on the profitability of each production system. There was a positive correlation between age and feed intake (r2= 0.40), slaughter weight (r2= 0.97), cold carcass yield (r2= 0.48), skin surface area (r2= 0.39), skin grade (r2= 0.19) and total yield of feathers (r2= 0.29). The dry skin grade showed deterioration as slaughter age was prolonged. Highly significant differences (P< 0.01) in slaughter weight, cold carcass yield, skin surface area, dry skin grade and total feathers were detected at the different slaughter ages. There were no significant differences (P> 0.05) with respect to gender for slaughter weight, skin surface area and dry skin grade within the different age groups. Males had significantly higher (P< 0.05) cold carcass yield and total feather yield than their female counterparts. From this study it can be concluded that an increase in slaughter age significantly increases feed intake, slaughter weight, cold carcass yield, and skin surface area. It is also clear that an increase in slaughter age can be detrimental to dry skin grade. The relative income contribution of the three main products (skin: meat: feathers) occurred in a ratio of 47:53:0, 52:47:1, 47:50:3, 44:51:5, 39:56:5 at the respective slaughter ages. Total income revealed an increase of 26 percent from 8.5 to 10.5 months slaughtering, an increase of 4 percent between 10.5 and 12.5 months, and an increase of 11 percent between 12.5 and 14.5 months. The income dropped by 0.3 percent between 14.5 and 16.5 months slaughtering. Total costs increased with slaughter age, particularly feed costs which showed an increase (at a decreasing rate) between the different slaughter ages. The margin above specified cost per bird was the highest for birds slaughtered at the age of 10.5 months. The margin above cost showed a steady decline as birds were slaughtered at higher ages. Slaughtering at 16.5 months revealed a negative margin. To compare the effect of differences in time span on different slaughter age regimes, margin above costs for each system over 5 years were discounted to a present value. In this study, with current feed costs and income from end products, slaughtering at 10.5 months revealed the highest present value for the margin above cost. Furthermore, slaughtering at 16.5 months revealed a negative present value on the margin above cost after 5 years. Financial viability calculations are relevant and valid for data obtained in this case study. Financial viability is however case-specific and may vary between producers, depending on their individual management practices, production systems and cost structures. Results from this study may be of significant value to managerial decision-making in the ostrich industry.

- Description: Information is a critical asset without which an organisation could not survive. The adequate and effective governance of this asset is an essential function and is the direct responsibility of the board and senior management. The board and senior management have a responsibility to maintain the financial and material health of their enterprise and this includes setting the proper direction and governance of the information asset. Many organisations have, over the past few years, suffered severe losses and failures due to the inadequate governance and protection of this valuable asset. The reasons for the lack of corporate information governance need to be examined. The board and senior management need to direct and control their organisations effectively, with the appropriate delegation of responsibilities, to reduce the possibility of suffering similar losses and/or failures. The contribution made by this study is illustrated in the designing of a framework and activity plans to facilitate the board in practically implementing an improved corporate information governance process.

- Description: This dissertation sets out to find a pragmatic solution for optimizing both resolution and rendering issues in the context of contemporary environmental design computer modelling. In this regard the following issues are addressed: Firstly, determining (with reference to a limited selection of existing 3DS Max software and plugins (i.e. VRay and Mental-Ray), which specific piece of software produces the best compromise as far as visual accuracy is concerned whilst still offering the designer the best scope for further design manipulation. Secondly, establishing design techniques which can increase the speed of model making as well as reduce rendering time without having an adverse effect on issues such as resolution and image quality. Lastly, ascertaining the least number of surfaces for a typical geometrical shape (e.g. chair, table, ornament etc.) without losing visual veracity by manipulation of the design itself. The research strongly supports the notion that VRay is the best overall software to be employed as a base before applying any design solutions. In this latter regard a number of solutions became evident as a means to both save memory and cut down on rendering time, including such factors as using spotlight rather than an omni light when rendering, because omni light calculations include the generation of needless shadows. The beneficial effect of employing ‘target direct’ light and reducing the area of light in order to decrease the calculation of shadow. Eliminating objects which do not need shadows from the lighting calculation and shutting off the reverberation and refraction factors before rendering. It was also confirmed that a black and white mipmap is better than a colour mipmap as far as saving on the system’s memory.

- Description: Thamnochortus insignis (Albertinia thatching reed) is a restio specie which is endemic in the narrow (20 km wide) coastal dune veld, from the Gouritz River in the east to the Breede River in the west (120 km). The area within this belt, where this reed is the dominant restio, covers 65 500 hectares. The culms of the reed is harvested as a natural product from the veld and used as thatch on roofs of houses. The traditional use has been as roofing material in Cape Dutch architecture. At this time, thatch roofs are regarded as a luxury commodity and are used in prestigious residential areas and also eco-friendly housing developments. The first section of the research project was based on a Delphi technique questionnaire completed first by 37 and secondly by 10 stakeholders in the industry. This group of growers, contract harvesters, crop agents and thatchers represented 80 percent percent of the estimated 2005 harvest and 87 percent of the estimated farm gate crop value. The thatching reed industry is the main agricultural enterprise situated in the coastal dune veld of the Southern Cape, i.e. 55 percent of total Gross Product Value generated by the survey respondents. The second section is based on an analysis of experimental harvest plots (50 m2), selected at random (4 replications per site) in the 2 x 3 different production systems, i.e. traditional harvest from natural veld, harvest from veld which had been subjected to mechanical injury ("sleep") and harvest from established orchard-type lands. Harvest data was collected at each site in terms of the following components, i.e. number of harvestable tussocks, circumference of tussocks and number of reed bundles (minimum circumference 210 mm, minimum length 1,2 m). The gross income per site was calculated on the basis of R1,80 per bundle (2006-price level). Economic analysis (Gross Margin above selected costs) indicates that plant density (reed tussocks/ha) is a critical factor, in order to offset the establishment cost of R2 100/ha in established lands, which is not incurred in the other two production systems. Economic returns from the first planted lands (2 100 and 2 900 plants/ha) averaged R7 666/ha against R8 781/ha for the mechanical-injury plants. However, at a density of 5 000 plants/ha, the projected Gross Margin increases to R15 765/ha. The use of mechanicalinjury and natural vegetation production systems both interfere with biodiversity and raise major concerns with regard to sustainability of the sensitive coastal dune fynbos. ANOVA-analysis of the data indicates a highly significant difference (p = 0,01) for all sites and production systems. Statistical analysis of averages indicates that mechanical injury treatment results in a significant increase in the number of tussocks, when compared to established and natural veld, respectively. The variance in the circumference of tussocks was greatest in natural veld (55 to 71 percent) and mechanical injury (54 to 61 percent). Tussocks harvested from established plantings reflected the least level of variance (28 to 38 percent). The larger reed tussocks in the established lands produced more bundles of marketable reed (8 200/ha) than the mechanical-injury (7 625/ha) and natural veld (3 450/ha) respectively. Establishment of T. insignis plantlets in an "orchard" system at spacings of 2 m x 1 m on previous winter cereal lands or old pastures, is shown to meet all the requirements within a sustainable production system, i.e. viability, productivity, environmental-friendly, risk management and social acceptance. Furthermore, the quality of the yield was in line with the proposed grading standard for thatching reed, i.e. minimum circumference 210 mm, minimum length 1,2 m and less than 6,5 percent grey culm content.

- Description: Thamnochortus insignis (Albertinia thatching reed) is a restio specie which is endemic in the narrow (20 km wide) coastal dune veld, from the Gouritz River in the east to the Breede River in the west (120 km). The area within this belt, where this reed is the dominant restio, covers 65 500 hectares. The culms of the reed is harvested as a natural product from the veld and used as thatch on roofs of houses. The traditional use has been as roofing material in Cape Dutch architecture. At this time, thatch roofs are regarded as a luxury commodity and are used in prestigious residential areas and also eco-friendly housing developments. The first section of the research project was based on a Delphi technique questionnaire completed first by 37 and secondly by 10 stakeholders in the industry. This group of growers, contract harvesters, crop agents and thatchers represented 80 percent percent of the estimated 2005 harvest and 87 percent of the estimated farm gate crop value. The thatching reed industry is the main agricultural enterprise situated in the coastal dune veld of the Southern Cape, i.e. 55 percent of total Gross Product Value generated by the survey respondents. The second section is based on an analysis of experimental harvest plots (50 m2), selected at random (4 replications per site) in the 2 x 3 different production systems, i.e. traditional harvest from natural veld, harvest from veld which had been subjected to mechanical injury ("sleep") and harvest from established orchard-type lands. Harvest data was collected at each site in terms of the following components, i.e. number of harvestable tussocks, circumference of tussocks and number of reed bundles (minimum circumference 210 mm, minimum length 1,2 m). The gross income per site was calculated on the basis of R1,80 per bundle (2006-price level). Economic analysis (Gross Margin above selected costs) indicates that plant density (reed tussocks/ha) is a critical factor, in order to offset the establishment cost of R2 100/ha in established lands, which is not incurred in the other two production systems. Economic returns from the first planted lands (2 100 and 2 900 plants/ha) averaged R7 666/ha against R8 781/ha for the mechanical-injury plants. However, at a density of 5 000 plants/ha, the projected Gross Margin increases to R15 765/ha. The use of mechanicalinjury and natural vegetation production systems both interfere with biodiversity and raise major concerns with regard to sustainability of the sensitive coastal dune fynbos. ANOVA-analysis of the data indicates a highly significant difference (p = 0,01) for all sites and production systems. Statistical analysis of averages indicates that mechanical injury treatment results in a significant increase in the number of tussocks, when compared to established and natural veld, respectively. The variance in the circumference of tussocks was greatest in natural veld (55 to 71 percent) and mechanical injury (54 to 61 percent). Tussocks harvested from established plantings reflected the least level of variance (28 to 38 percent). The larger reed tussocks in the established lands produced more bundles of marketable reed (8 200/ha) than the mechanical-injury (7 625/ha) and natural veld (3 450/ha) respectively. Establishment of T. insignis plantlets in an "orchard" system at spacings of 2 m x 1 m on previous winter cereal lands or old pastures, is shown to meet all the requirements within a sustainable production system, i.e. viability, productivity, environmental-friendly, risk management and social acceptance. Furthermore, the quality of the yield was in line with the proposed grading standard for thatching reed, i.e. minimum circumference 210 mm, minimum length 1,2 m and less than 6,5 percent grey culm content.

- Description: Plague is a classic zoonosis caused by the bacterium Yersinia pestis and is subject to the International Health Regulations, 1969. In the last two millennia, plague has become widespread, with three pandemics occurring in the 6th, 14th and 20th centuries. Currently, plague outbreaks and epidemics still occur worldwide. This study attempts to develop formal work methods and procedures for plague surveillance and control by environmental health practitioners as a strategy to ensure that field data can be integrated within the municipal, provincial and national spheres of government. A qualitative, explorative, descriptive, inductive and deductive research design was followed. A documentary research approach was employed as the primary method of data collection. To obtain additional information, both semi-structured personal interviews and physical observations during plague surveillance were adopted by the researcher. The organisational structure of the health care system in South Africa was analysed to identify and explain the role and functions of relevant decision-makers related to the surveillance and control of plague within the different spheres of government. Legislative measures regarding plague surveillance and control were also presented. As a prerequisite for the development of work methods and procedures for plague surveillance and control, the epidemiology of plague was discussed with emphasis on the distribution and characteristics of the disease in South Africa. Important rodent reservoirs and flea vectors of plague in South Africa were identified. Clinical manifestations, diagnosis and treatment of plague were described and discussed. Within this qualitative study an attempt has been made to develop work methods (xiii) and procedures for plague surveillance and control in South Africa. Relevant field data forms to be used during plague surveillance and control strategies were also developed. Recommendations emanating from the study can be found in the final chapter.

- Description: Recently, organisations have been faced with challenges like never before. Increasing competition from businesses across the world has meant that businesses must be more careful about the choice of strategies to remain competitive. This situation has placed more focus on organizational effectiveness in that systems and processes be applied in the right way to the right things to achieve results. All of the organisational processes must continue to be aligned to achieve the overall results desired by the organisation for it to survive and thrive. Performance management is an ongoing process that should reflect the current and emerging business challenges, as well as the company’s values about performance and careers. As the business and workforce change, the performance management process should be modified to ensure that the process and tools remain congruent with organisational values and priorities. The objective of this study was to identify the influence of the current performance management system, in the Finance department at General Motors South Africa, as a facilitation tool in aiding or assisting management in achieving individual and departmental goals. To achieve this objective a comprehensive literature study was performed to determine the views on performance, and on performance management systems. A questionnaire was designed based on the guidelines in the literature study, in order to establish the extent to which the organisation manages performance. The researcher used the random sampling method of selection and distributed the questionnaire to eighty one potential respondents via mail and electronic e-mail. Forty one completed questionnaires were returned and these were processed and -iiianalysed using Microsoft Office Excel 2003, running on the Windows XP suite of computer packages. The respondent’s opinion obtained from the questionnaires were compared with the guidelines provided by the literature study in order to identify shortcomings of the influence that the performance management system has on the achievement of individual and departmental goals at the selected organisation. It can be concluded from the respondent’s opinions that the greatest shortcomings of the current performance management system are the link between performance and reward, and commitment to the process in its totality. The other areas of concern are the lack of training and development, and the necessary resources required to achieve objectives. The study also indicates there is no overwhelming agreement that feedback, both positive and negative, takes place as the literature suggests. The following were the main recommendations and conclusions made: • Firstly, it is imperative that management undergoes training in the feedback and review process which is a critical element in the performance management cycle. • Secondly, to realise the benefit of increased employee effectiveness, management should undergo training to become more effective career coaches to promote a climate of continuous learning and professional growth. • Thirdly, the reward system should be reviewed, if management is committed to using pay as an incentive for desired levels and directions of performance. • Fourthly, management can set an example and build commitment for effective performance management and be leaders at all levels.

- Description: Information Security is becoming a part of the core business processes in every organization. Companies are faced with contradictory requirements to ensure open systems and accessible information while maintaining high protection standards. In addition, the contemporary management of Information Security requires a variety of approaches in different areas, ranging from technological to organizational issues and legislation. These approaches are often isolated while Security Management requires an integrated approach. Information Technology promises many benefits to healthcare organizations. It helps to make accurate information more readily available to healthcare providers and workers, researchers and patients and advanced computing and communication technology can improve the quality and lower the costs of healthcare. However, the prospect of storing health information in an electronic form raises concerns about patient privacy and security. Healthcare organizations are required to establish formal Information Security program, for example through the adoption of the ISO 17799 standard, to ensure an appropriate and consistent level of information security for computer-based patient records, both within individual healthcare organizations and throughout the entire healthcare delivery system. However, proper Information Security Management practices, alone, do not necessarily ensure regulatory compliance. South African healthcare organizations must comply with the South African National Health Act (SANHA) and the Electronic Communication Transaction Act (ECTA). It is necessary to consider compliance with the Health Insurance Portability and Accountability Act (HIPAA) to meet healthcare international industry standards. The main purpose of this project is to propose a compliance strategy, which ensures full compliance with regulatory requirements and at the same time assures customers that international industry standards are being used. This is preceded by a comparative analysis of the requirements posed by the ISO 17799 standard and the HIPAA, SANHA and ECTA regulations.

- 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.
