- Description: Literature suggests that a small number of family businesses are able to make the transition from the founder to other family members with a common reason cited being the lack of planning. This study aims to build understanding of leadership succession in family businesses by focusing on the influence of a founder's family business value set on the succession planning process in Black family-owned businesses. Using the Strauss and Corbin (1990) grounded theory method, this study develops a theory of succession planning of Black familyowned businesses labelled Passing the Spear which is comprised of three stages based on an analysis of 21 qualitative interviews. The Spear was an analogy used to represent both the values of the founder and the family business, thus in Passing the Spear, founders where essentially performing a dual transfer of their values and leadership to the successor. The implementation of the process Passing the Spear was influenced by the family business value set of the founder, which in this study, were labelled as Traditional, Progressive, and Transitional. These value sets were distinguished by their behaviour regarding their choice of successor where founders with a traditional value set exhibited gatekeeping behaviour, while the behaviour of founders with a progressive value set was labelled navigating, and finally, founders with a transitional value set demonstrated behaviour labelled exploring. Furthermore, it was found that after the successor had been chosen, founders appeared to follow a generic succession planning process, however, the ease and timing of implementation was influenced by the family business context, evidence of being proactive and the degree of family business resilience. The process of Passing the Spear comprised of three stages of (a) Showing the spear where the founder's focus is on the induction and socialization of the successor using the strategies of bringing the successor into the family business and managing the family-business interface using relationships; (b) Explaining the spear entailed founders using the strategies of sharing knowledge and teaching the successors about the family business; and ( c) Sharing the spear was where founders focused on empowering the successors by implementing strategies of sharing responsibilities and learning from the successor.The process provides insights into the influence of family business values on the succession planning process and can be useful for founders of Black family-owned businesses in planning for succession in their businesses. In addition, the study provides another perspective of succession planning and offers a contribution to the literature for understanding succession in Black family-owned businesses.

- Description: Arid and semi arid environments are characterised by extreme fluctuations in temperature and low rainfall which present significant challenges to the animals inhabiting these areas. Mammals, such as aardvarks (Orycteropus afer, Pallas 1766), excavate burrows in order to avoid predators and climatic extremes and are termed “ecosystem engineers” as they physically modify their environment and in doing so create new habitats and alter the availability of resources to other species. In this study I assessed the microhabitat conditions (maximum and minimum temperature, relative humidity and seed abundance) of aardvark burrows in relation to paired control sites. In addition, I evaluated the use of aardvark burrows by other vertebrate and invertebrate species and investigated the impact of aardvark burrow mounds on landscape scale floristic diversity. Maximum temperatures were significantly lower (p < 0.05) and minimum temperatures and midday humidity were significantly higher (p < 0.05) inside the burrows at the three study sites, Kwandwe Private Game Reserve (Kwandwe), Mountain Zebra National Park (MZNP) and Tswalu Kalahari Reserve (Tswalu). There were no significant differences between the concentration of seeds, the average numbers of unique individual small mammals, trap success or small mammal species richness recorded inside the burrows compared to outside (p > 0.05). At all three sites, small mammal species diversity was higher in the burrows but this result was also not significant (p > 0.05 for all). Trap success and the number of individuals captured was higher at Tswalu than the other two sites (p < 0.05 for both). The different methods used in this study revealed a total of 25 mammal, seven bird, one amphibian and six reptile species utilising aardvark burrows. There were significant differences in insect community assemblages between the burrows and open control areas at Kwandwe and Tswalu (p < 0.05 for both) but not at MZNP (p > 0.05). The parasitic guild was more prominent inside the burrows than outside but their abundance was not as high as anticipated, possibly due to the placement of traps closer to the burrow entrances than the sleeping chambers. The complex structure of the burrows prevented the placement of traps in close proximity to the sleeping chambers. As expected, the amount of bare earth was significantly higher on active and recently abandoned burrow mounds compared to the old burrow mounds and reference plots at all three sites (p < 0.05 for all), with the exception of the active burrows at Tswalu. Overall, the different plot types were characterised by significantly different plant communities during all the seasons at MZNP, during three of the seasons at Kwandwe and only during winter at Tswalu. The total species richness recorded on the reference plots was higher than on the burrow mounds at all three sites. However, species diversity on the reference plots was not significantly higher than the burrows at any of the sites (p > 0.05 for all sites). Although the results were not significant, the overall species diversity at a site level was greater than the reference patches at Kwandwe and Tswalu (p > 0.05 for both). Aardvarks fulfil the criteria of a significant ecosystem engineer and their presence in arid and semi-arid environments is likely to be critical to the survival of other individual organisms and species, particularly when alternative burrowing animals are either absent or restricted in their activities. Thus, aardvark populations should be considered a conservation priority in arid and semi-arid ecosystems.

- Description: The effect of magnetic fluid (MF) on the photophysical and photochemical parameters of zinc and aluminum phthalocyanines are reported. The complexes studied are zinc (II) phthalocyanine (ZnPc), chloroaluminum phthalocyanine ((Cl)AlPc) and tetrasulfonated aluminum phthalocyanine ((Cl)AlTSPc). The parameters are studied in dimethylsulfoxide (DMSO) for all complexes and also in aqueous media for (Cl)AlTSPc. The triplet lifetimes for (Cl)AlTSPc and ZnPc decreased while the triplet quantum yields increased in the presence of MF. For (Cl)AlPc, the triplet lifetimes were found to increase with decrease in laser energy while there was photoreduction to the Pc−3 species. Singlet oxygen and photodegradation quantum yields decreased in the presence of MF, suggesting quenching.

- Description: The comparative photocatalytic activities of aryloxy and arylthio tetrasubstituted oxotitanium(IV) phthalocyanine complexes for the oxidation of 1-hexene in DCM are reported for the first time. The singlet oxygen quantum yield, photostability and photocatalytic properties are investigated. The catalysts effectively catalyse 1-hexene to 1,2-epoxyhexane and 1-hexen-3-ol as major and minor products respectively. The photooxidation products are formed via two reaction mechanisms, namely via singlet oxygen (Type II) and radical (Type I) reaction pathways. These are also dependent on the singlet oxygen quantum yields and photostabilities of the phthalocyanines. Complex 1a that is peripherally substituted with phenoxy groups exhibited the best activity in terms of overall performance.

- Description: This document aims to provide a complete discussion on vulnerability and patch management. The first chapters look at the trends relating to vulnerabilities, exploits, attacks and patches. These trends describe the drivers of patch and vulnerability management and situate the discussion in the current security climate. The following chapters then aim to present both policy and technical solutions to the problem. The policies described lay out a comprehensive set of steps that can be followed by any organisation to implement their own patch management policy, including practical advice on integration with other policies, managing risk, identifying vulnerability, strategies for reducing downtime and generating metrics to measure progress. Having covered the steps that can be taken by users, a strategy describing how best a vendor should implement a related patch release policy is provided. An argument is made that current monthly patch release schedules are inadequate to allow users to most effectively and timeously mitigate vulnerabilities. The final chapters discuss the technical aspect of automating parts of the policies described. In particular the concept of 'defense in depth' is used to discuss additional strategies for 'buying time' during the patch process. The document then goes on to conclude that in the face of increasing malicious activity and more complex patching, solid frameworks such as those provided in this document are required to ensure an organisation can fully manage the patching process. However, more research is required to fully understand vulnerabilities and exploits. In particular more attention must be paid to threats, as little work as been done to fully understand threat-agent capabilities and activities from a day to day basis. , TeX output 2007.02.08:2212 , Adobe Acrobat 9.51 Paper Capture Plug-in

- Description: The tourism industry has been identified as the industry with the most potential to create jobs and contribute largely to economic growth. In order to live up to this potential, tourism businesses need to create tourism products for potential tourists which need to be promoted successfully through a number of mediums. The use of the Internet as a medium for promoting and selling tourism products is increasing, however, in order for tourism businesses to successfully promote the tourism product through the Internet, they have to understand the needs and wants of their current and potential target markets. One segment of the tourism market that has come under increasing attention is the mature traveller market. This market is defined as travellers who are 50 years of age and older. Generally, the mature traveller market is viewed as a small homogenous group of old consumers with little or no spending power. However, evidence suggests that this market is comprised of an increasing number of diverse people, who use the Internet and like to spend on tourism products. Therefore, this research will examine differences between Internet users and Internet non-users in the mature traveller market. Specific attention will be paid to investigate differences in demographic, socioeconomic, Internet use and travel-related characteristics. The identification of these characteristics will enable a profile to be d~veloped for each group, which can be used by tourism businesses to effectively promote tourism products over the Internet to the mature market In order to collect data from potential respondents, a questionnaire which was used in a similar study conducted in the US was used. Data was collected using a convenience sample of Internet users and Internet non-users from the Eastern Cape and Gauteng provinces of South Africa. Cronbach alpha and factor analysis were used to assess the reliability and validity of the research instrument and measurement scales. In order to test whether differences did exist between the two groups the Chi-square and t-test statistics were used. Finally in order to examine which factors where influential in differentiating between Internet users and Internet non-users discriminant analysis was employed. The findings in the present study suggest that there are significant differences in demographics, socioeconomic, Internet use and travel-related characteristics between Internet users and Internet non-users in the mature market. By understanding the differences between Internet users and Internet non-users, tourism businesses can identify marketing strategies that appeal to mature travellers who use the Internet and to those do not, by utilising information gathered from Internet users and Internet non-users demographic, socio-economic and travel-related characteristics.

- Description: The Working for Water (WfW) Programme is a public works programme designed to clear South Africa of invasive alien vegetation and to restore lowwater consuming indigenous vegetation in the areas that have been cleared. Funds to clear alien invasives were initially secured on the basis that such a programme would increase water runoff, facilitate biodiversity and ecosystem functioning, and provide social benefits through job creation. The economic merits of the Programme, in terms of increased water yields, has been established in the Western Cape and KwaZulu-Natal, but questioned in the Eastern and Southern Cape. However, there are economic aspects of the studies carried out in the Eastern and Southern Cape that merit more attention than was given them; one of these being the issue of non-water benefits. Preliminary figures emanating from contingent valuation pilot studies conducted at six WfW projects sites indicated that one of these non-water benefits, namely the biodiversity and ecosystem resilience benefit, could be substantial. As such, the primary objective of the present study was to apply the contingent valuation method (CVM) to value people’s preference for indigenous vegetation. This value was intended to serve as a proxy for increased biodiversity and ecosystem resilience at three WfW sites. Despite the controversy surrounding the CVM, it has been found that it is a credible valuation tool. The CVM’s merits lie in its versatility and in the fact that it is the only method available which is capable of obtaining estimates of both nonuse and use values, thus making it applicable for valuing biodiversity. The primary aim of a CVM study is to determine an estimate of the total willingness-to-pay (WTP). In this study, the total WTP figure was calculated by multiplying the median WTP for the local WfW Programme by the total number of user households. The respective total WTP amounts are shown in Table 1. It was anticipated that respondents would be willing to pay more for the national WfW Programme, than for the less inclusive good (i.e. the local WfW Programme). The results correspond with this expectation at the Port Elizabeth and Underberg sites. However, due to strategic factors Worcester respondents were willing to pay more for the local WfW Programme than for the national Programme.

- Description: It is an oversimplification to look only at the manner in which a two-dimensional drawing suggests a three-dimensional movement in order to study choral conducting gestures. It must be recognised that there is a myriad of tacit aspects of knowledge surrounding conducting gestures. These aspects of tacit knowledge might be the reason why the teaching of conducting is done mostly in a continuous practicum, where the apprentice learns from the master, because in the practical situation the novice learns not only explicit knowledge, but also tacit knowledge. On the other hand, it is vital that the process of categorising and theorising about gestures continues in order to at least gain a better explicit knowledge of the process. In doing so, a theoretical knowledge base will strengthen the body of knowledge. This explicit knowledge should contain information with regard to the anatomy of the conductor, a basic understanding of a balanced posture, bilateral symmetry and vertical alignment, and a basic knowledge which will help to understand which main muscle groups are responsible for which basic movements involving gestures. The study of gestures from a theoretical point of view is barely more than five decades old. The demands which 20th and 21st century composers make on conductors question the traditional approaches of the functions of the hands. It has become essential for a conductor to develop greater skill of ambidexterity in order to cope with these demands. Despite the notion by some authors that choral conducting gestures employ standard gestures, it has been shown in this study that this is simply not the case. An overview of the work of authors in the field of conducting gestures was presented through a literature study. Concepts and their definitions have been selected and explained through the answering of research questions. Definitions of parameters and functionality of gestures were clarified to decide which gestures were the most appropriate in certain circumstances. This theory aims to be both descriptive and normative. It is descriptive in the sense that the concepts and issues and relationships around the characteristic aspects of gestures are indicated. It is normative in terms of the suggestions offered with regard to issues pertaining to gestures. This thesis sets out to contribute to the formulation of theoretical aspects of choral conducting gestures in an effort to codify and structure knowledge which is often stored in composers minds and experience, in an effort to pass down this knowledge to other apprentices in the field.

- Description: The issue of decentralisation has been one of the top priorities of the Namibian education system since independence in 1990. One of the decentralisation aims was to enhance parental involvement in education by establishing School Boards. However, School Boards and the role of parents in school management have been considered ineffective for several years which led to the promulgation of Education Act 16 of 2001 in which the roles of School Boards are strengthened and clarified. This study sought to investigate School Board members’ perceptions, understanding and experiences of parents’ involvement in school governance more specifically after the implementation of the Education Act of 2001 in 2003. This study is an interpretive case study of one combined rural school in the Ohangwena educational region of Namibia. This research employed three data collection techniques, namely semi-structured interviews, observation and document analysis. The main findings of this study reveal that there is a lack of joint understanding and shared vision between educators and parents in the School Board. This problem underpins other more symptomatic problems, such as lack of accountability in the matter of school finances, differences in understanding the roles of School Board members and lack of parents’ motivation from the school management. The study further reveals the ineffectiveness and insufficiency of the training provided in the past. It highlights some of the challenges that hinder the effective involvement of parents in rural school governance, such as poor educational background among parents, poor knowledge of the English language and poor understanding of educational issues. However the findings also acknowledge parents’ participation and their full involvement in decision-making. The findings show that the new School Board elected in terms of the Education Act of 2001 has been more effective than previous School Boards and has reached a number of achievements such as being instrumental in solving disciplinary problems, purchasing school assets and renovating classrooms. Recommendations for practice and for further research are made.

- Description: Traditional views on International Relations dominate regional analyses. These invariably emphasize the dominance of state and market forces in inter-state relations. Experiences and expectations of people are less prominent in these discourses, and the practices they foster. This thesis critically analyses the regional processes in West and southern Africa within the framework of Critical Theory. It argues that these processes are constrained by instability and the increasing legitimacy crises of the State. The thesis demonstrates that the State, through exclusive nationalist practices, hinder the growth of a cosmopolitan order, and it argues that neo-liberal regionalism is a contested phenomenon because of its exclusive nature. Finally, the thesis suggests steps needed to resolve the legitimacy crises and to build an inclusive regional order, based on cosmopolitan values.

- Description: After careful review of all the relevant literature pertaining to motivation, performance management and compensation in the form of incentives, this thesis focuses primarily on determining whether a statistically significant relationship exists between individual needs and the choice of an incentive scheme option. The secondary aims of the research are to determine whether: A relationship exists between the job grade of an individual and the choice of an incentive scheme. A particular incentive scheme option is preferred by the employees in The South African Breweries (SAB). A particular preference exists, and if so, to make recommendations to SAB for consideration as alternatives to their existing incentive scheme options. After collation of the survey data from the respondents in the sample, the analysis and discussion of the results determined that no significant relationship exists between individual needs and the choice of an incentive scheme option. It was, however, determined that a significant relationship exists between the grade of the employees in SAB and their choice of an incentive scheme. 81% of all respondents indicated a desire for shares as an option in their Short Term Incentives (STI) which indicates a desire for shares in some form or another and may well indicate a level of confidence and commitment by the employees to the organisation. Although the research hypothesis was not proven, significant insights into remuneration within SAB was obtained, which has resulted in recommendations being made for further research into the option of shares in some form or another in the organisation. A further recommendation for SAB is to consider some form of share options for all employees in the organisation. As many other organisations that are performing at remarkable levels attest this performance to share ownership and the behaviour that emanates from it, it would be in the interests of SAB to further investigate the issue as it may improve performance, ownership and retention within the company.

- Description: This case study examines the introduction of Indigenous Knowledge (IK) in the Consumer Studies curriculum of Further Education and Training (FET). The research is centred on the use of enquiry methodologies involving learners observing parent demonstrations of the making of ‘amarewu’ and other activities centred on the propositional knowledge dealing with fermentation in the Consumer Studies curriculum. The research involved a review of curriculum documents, participant observation of a demonstration of local food practices related to ‘amarewu’ and learner research activities and interviews to review the developing learning interactions. The learning activities were focused on the learners’ researching the cultural and nutritional value of ‘amarewu’ and included an audit of food consumed in the community. What transpired from this study was that working with IK in the curriculum is possible. The inclusion of IK is not only possible but desirable and has exciting possibilities for relevance in contemporary education. The active involvement in parent demonstration engaged the learners in IK in their mother tongue, therefore indigenous knowledge has relevance. The curriculum concepts also enhanced the engagement by giving rise to more relevant knowledge and a respect for cultural matters. Intergenerational capital and subject concepts also enabled learners to engage with local nutritional problems and to come up with practical solutions. This study demonstrates how IK intergenerational capital in combination in combination with curriculum concepts (subject knowledge capital) can enhance relevance and the learners’ real engagement with local health and nutritional problems. Not only did the learners have culturally valued knowledge, but also knowledge that has a practical grasp of the problem and that they could use to engage relevant issues. These two views of knowledge join in learning and can be used to address health issues. I therefore recommend connection of cultural knowledge and conceptual knowledge to strengthen the revitalisation of cultural heritage, thus equalising it to the modern patterns of life and enhancing meaningful curriculum orientation.

- Description: The ecologist Garrett Hardin (1968) introduced a useful concept called the tragedy of the commons, which describes how ecological resources become threatened or lost. The term “commons” is based on the commons of old English villages and is symbolic of a resource that is shared by a group of people. If every person were to use each resource in a sustainable fashion it would be available in perpetuity. However, if people use more than their share they would only increase their personal wealth to the detriment of others. In addition, an increase in the population would mean that the size of each share would have to decrease to accommodate the larger number of people. As a result, resources are threatened by personal greed and uncontrolled population growth. Freshwater is an example of a common resource that is under threat in South Africa where the average annual rainfall is less than 60 percent of the global average (Mukheibir & Sparks 2006). The increasing demands for freshwater as well as its eutrophication are major concerns with regards to estuarine health, environmental resource management and human health. The correct management of water is necessary to ensure that it is utilised in a sustainable manner. The National Water Act (No. 36 of 1998) has provided the rights to water for basic human needs and for sustainable ecological function; the Basic Human Needs Reserve and Ecological Reserve are both provided as a right in law. The amount of water necessary for an estuary to retain an acceptable ecological status, known as the Estuarine Ecological Reserve, is determined through the implementation of procedures (rapid, intermediate or comprehensive) compiled by the Department of Water Affairs and Forestry (1999) in its Resource Directed Measures (RDM) for the Protection of Water Resources. The impact of restricted flow on estuaries can be reduced by manipulating the water released from impoundments, the regulation of water abstractions within the river catchment or both (Hirji et al. 2002). The reserve assessment method is designed to evaluate ecosystem requirements by employing groups of specialists from different disciplines. In South Africa, this includes hydrologists, sedimentologists, water chemists and biologists (including microalgae specialists). The use of microalgae in ecological assessments has largely been based on research that was initiated at the Nelson Mandela Metropolitan University (formerly University of Port Elizabeth) and subsequently at Rhodes University (Grahamstown) and the University of KwaZulu Natal (Durban). The microalgal research can be divided into two main focus areas; phytoplankton and benthic microalgae

- Description: The study investigates how rural Grade 4 teachers and learners experience the transition from Oshikwanyama to English as a medium of instruction. The study was conducted at a rural school in Oshana region in northern Namibia. The research site and participants were purposefully selected. Grade 4 teachers and learners were interviewed and observed. Relevant documents were also analyzed. The purpose was to understand participants’ experiences, perceptions and practices in relation to their experience of the transition to English medium instruction. The study revealed out that both Grade 4 teachers and learners are struggling to teach and learn through the medium of English. This was borne out by participants’ responses, classroom practices and document analysis, especially learners’ oral presentation and written work. The conclusion is drawn that limitations in English proficiency overshadow the good intentions of the curriculum. This was evident in the fact that Grade 4 learners at a selected school found it difficult to cope with the demands of the curriculum. In addition, most of the learners have poor literacy skills even in their mother tongue, Oshikwanyama. In the linguistic sense, proficiency in the first language can pave the way for second language to flourish. If the reverse is the case then the learner might find it difficult to acquire linguistic skills in the second language. The study concludes that for the sake of effective learning, an intervention on professional development needs to be in place. This might help rural lower primary teachers to upgrade their existing skills particularly in terms of the English language proficiency as well as how to prepare learners for the transition to English.

- Description: Entrepreneurs typically live with the ever present threat of business failure arising from limited financial resources and aggressive competition in the marketplace. Under these circumstances, conflicting priorities arise and the entrepreneur is thus faced with certain dilemmas. In seeking to resolve these, entrepreneurs must often rely on their own judgment to determine ‘‘what is right’’. There is thus a need for a technique to assist them decide on a course of action when no precedent or obvious solution exists. This research paper examines how entrepreneurs experience and deal with these dilemmas. The research is based on interviews with seven entrepreneurs in established service-oriented ventures, which gave rise to 26 dilemmas. These dilemmas were analyzed by making use of the Synergy Star technique, which is introduced here as a tool that is useful in defining any dilemma, isolating the ethical component, and resolving the dilemma in a way that is congruent with the entrepreneur’s personal world-view.

- Description: Literature has been reviewed on the formation and structure of groups and teams in order to establish what differences there are in the types of teams that exist in the modern workplace, and what it is that facilitates effective and high performance of such teams. From the results of the qualitative research conducted, the author is of the opinion that the notion of teams operating in the regulated casino environment is somewhat exaggerated. At year end functions and award ceremonies, mention is made of the teams that successfully contributed to the various achievements but, upon closer inspection, no teams are evident at the “coal face”. Some of the reasons for this may be that there appears to be a lack of those skills necessary to harness people into successful teams especially during the early stages of the business lifecycle. Too few people at grass root level have the required knowledge, skills and attitude to take the lead and form a team especially in an unfamiliar environment. It may also be as a result of the different management styles imposed on the labour force over a long period of time. As organisations are forced to become more competitive, especially on the global market, it is the author’s opinion that the management style in progressive organisations will probably have shifted from autocratic to paternalistic to democratic; yet very few businesses are practicing participative management, although buzzwords relating to participative management are used freely. Ultimately, accountability rests with top management and results are measured by bottom line figures. Since accountability is centralised, the intrinsic and extrinsic rewards for success are also confined to management who is likely to be criticised, attacked, or got rid of, and these recipients are often not volunteering to share the benefits reaped – even though the recipients would mutter words such as “if it were not for my team” or “ thanks to my team”. With this viewpoint in mind the treatise aims to address specific and practical interventions that could be implemented without much organisational change and yet developing a culture of team development and team building within an organisation. The author is of the opinion that the responses imparted from the different respondents in the research results could benefit Sun International within its training methodology policy framework. Although, each casino unit is managed autonomously, Sun International, via its centralised training facility, could apply successful specific and practical training interventions in respect of team dynamics. Results extracted from unit staff climate surveys and staff feedback sessions could be collated from the different training departments within the group and presented in workshops at quarterly conferences and feedback seminars. The effectiveness of these interventions, once implemented, could be assessed in a performance measurement framework. Eales-White (1996: 34) quotes Peters as saying, “I observe the power of the team is so great that it is often wise to violate common sense and force a team structure on almost anything … companies that do, will achieve greater focus, stronger task orientation and enhanced individual commitment.

- Description: In today’s computing environment, awareness programmes play a much more important role in organizations’ complete information security programmes. Information security awareness programmes are there to change behaviour or reinforce good security practices, and provide a baseline of security knowledge for all information users. Security awareness is a learning process, which changes individual and organizational attitudes and perceptions so that the importance of security and the adverse consequences of its failure are realized. Therefore, with proper awareness, employees become the most effective layer in an organization’s security defence. With the important role that these awareness programmes play in organizations’ complete information security programmes, it is a must that all organizations that are serious about information security must implement it. But though awareness programmes have become increasing important, the level of awareness in most organizations is still low. It seems that the current approach of developing these programmes does not satisfy the needs of most organizations. Therefore, another approach, which tries to meet the needs of most organizations, is proposed in this project as part of the solution of raising the level of awareness programmes in organizations.
