- Description: The research thesis reflects a positive improvement to the plant efficiency through strategic optimisation planning and controlling systems. It’s important to note that the set goals of the research were achieved, with total employee buy-in contributing to the success and sustainability of these improvements. Purposive sample methods allowed for the twenty employees from a total of 172, to be interviewed for both the pre and post testing. The paradigm of the research contributed to integrative communication between brainstorming and action. The efforts of the total workforce must be commended, for strategically aligning the organizational goals and objectives to realization. The content of the thesis, show a direct relationship between the plant optimisation and the increase in the production volumes. The understanding of the downtime reports for the period specified is a direct reflection to the improvement in quality, and the reduction of the overall poor workmanship graphs indicates positively to the reduction in cost. The last value driver, on-time delivery shows a vast improvement in maintaining the customer satisfaction, when considering the increase to the production volume capacity. These improvements have made further volume increases probable, and the understanding of Ikhwezi Trucktech management to negotiate with realized information for future capacity planning.

- Description: Feminist theories emerged out of the revolutionary enthusiasm that swept the Western world during the late eighteenth and nineteenth century Europe. Based on the assumption that all persons have "inalienable or natural" rights upon which governments may not intrude, feminists in Europe and America advocated that equal rights should be extended to women who up to this point were not considered legal beings separate and deserving of these rights. Most African writers and feminists have argued that since most of the theories of feminist jurisprudence have their roots in this Euro-centric context, they cannot be applicable to African women and should therefore be discarded. The thesis acknowledges that to a certain extent their assertions are true. For years feminist jurisprudence has been restricted to an academic engagement with the law failing to take into account the practices and customs of different communities. It has largely been the realm of the middle class bourgeois white female and therefore has been inaccessible to the African woman. The thesis aims, however, to prove that these theories of feminist jurisprudence although Euro-centric have a place in the understanding and advancement of African women's rights in South Africa. In Chapter One the writer traces the history of South African women's rights and the laws that affect African women. Chapter Two presents the emergence of feminist theories and categories of feminism. The writer then seeks to identify the misunderstandings and tensions that exist between the two. The narrow conception of Euro-centric feminism has been that its sole purpose has been the eradication of gender discrimination, however, for African women in South Africa they have had to deal with a multiplicity of oppressions that include but are not restricted to gender, race, economic and social disempowerment. This is dealt with in Chapter Three. It is the opinion of the writer that despite these differences feminism does play a critical role in the advancement of women's rights in South Africa. Taking the South African governments commitment to the advancement of universal rights, the writer is of the opinion that African women can look to the example set by Western feminists, and broaden these theories to suit and be adaptable to the South African context. The answer is not to totally discard feminist theories but to extract commonalities that exist between African and European women, by so doing acknowledging that women's oppression is a global phenomenon. This is the focus of Chapter Four. To avoid making this work a mere academic endeavour, the writer in Chapter Five also aims, through interviews, to include the voices of African women and to indicate areas that still need attention from both the lawmakers and women's rights movements (Feminists). Finally, the writer aims to present a way forward, one that is not merely formal but also substantively attainable.

- Description: This paper deals with an analysis of the discursive accounts of Eastern Cape white commercial farmers on the subject of Democracy. Drawing on the theoretical perspectives of Social Constructionism and Discourse Analysis – which view individuals’ accounts of their realities as produced and informed by their particular social and historical context – the paper seeks to provide an analysis of the content of, and rhetorical strategies within the participants’ accounts and explanations. Such accounts of the social, historical and political circumstances in which Eastern Cape commercial farmers find themselves are thought to provide valuable insights into the manner in which the process of democratisation has been received by members of the agricultural sector. Data collection was conducted via brief, audio taped, semi-structured interviews. The participants were all white men and women, living in a commercial farming region of the Eastern Cape Province. Responses to the interviews were subjected to the Discourse Analytical procedure advanced by Ian Parker. Analyses reveal that participants are critical of the notion of democracy; utilize specific rhetorical and argumentation strategies; make use of notions and techniques of ‘Othering’; and subscribe to a colonial / patriarchal ideology which attempts to idealize pre-democratic South Africa. These findings illustrate what is in many ways still an ongoing political and ideological struggle in the rural regions of the country.

- Description: Riparian habitats in many parts of South Africa are severely degraded by invasive alien plants, especially trees. These invasions reduce water yields from catchments and affect riverine functioning and biodiversity. Initiatives are under way countrywide to clear alien plants from watercourses and surrounding catchments. Current understanding of key processes that regulate riparian functioning and define options for restoration is rudimentary. We review the impacts of riparian invasions and identify factors limiting the recovery of natural vegetation following alien clearance. We propose a framework of strategic interventions for optimizing restoration success. The framework identifies abiotic and biotic barriers to restoration at the scales of catchments and local reaches. In highly transformed catchments, interventions at the reach scale may fail if important barriers at the catchment scale are not addressed. The extent to which propagule supply and microsite conditions inhibit vegetation recovery is unknown. We also know little of the relative importance of dispersing vegetative propagules, dispersing seeds and soil-stored seed banks in vegetation dynamics, particularly after severe disturbances such as dense invasion by alien plants. The importance of geomorphological and hydrological factors in mediating recovery of riparian vegetation has not been adequately explored for all climatic areas in South Africa. More research is needed to determine the influence of different alien species and clearing treatments on the recovery of riparian vegetation. The literature strongly suggests that in highly alien-transformed catchments, the re-introduction of riparian species is required to promote recovery and suppress re-invasion. However, such interventions are unlikely to be widely implemented unless the cost: benefit ratios are favourable.

- Description: The objective of this study is to investigate the reasons for international assignments ending in failure, using the current models of expatriates’ premature withdrawal decisions, so as develop solutions to those problems. Studies of expatriate failure and effects of expatriate satisfaction on organisational performance have been conducted but most of them in the overseas countries. These studies revealed that the practice of employing expatriates is a strategic move on the part of the multinational corporation to increase the international experience and knowledge base of present and future managers. Even though studies on strategies that companies can use have been done extensively, research still shows that a large number of overseas assignments end in failure. Failure being described as the premature return to the home country, not being able to adjust in the host company or country and immediately living the company upon return from the assignment. It is for this reason that in the researcher decided to investigate what could be the reasons that cause the expatriates to return home early. The research will be of importance to South Africa firstly, as organisations that are operating globally will copy the business systems and processes practiced in developed countries, and later bring knowledge, skills and expertise that will help in boosting the economy of the country. Secondly, the organisation's Human Resource Management will develop practices to ensure the successful and effective retention of expertise. Expatriate failure will be reduced and the process of repatriating expatriates will be meaningful. Individuals assigned will not find it difficult to adjust in the parent company, and later take the skills they have learnt to another company. Thirdly, managers generally will understand the challenges that accompany expatriation, and be able to meet those challenges. The research becomes an investigative research as one tries to establish if there is concurrence or deviation with the current models. A sample is drawn from a list of international companies that have operations overseas. The researcher has tried to get responses from companies in all provinces of South Africa so that the sample can be fully representative. The questionnaire is used as it is a common instrument for observing data beyond the physical reach of the researcher. The questions were selected to address each of the factors affecting decisions to withdraw from the country of assignment. Responses from the expatriates have helped to develop a new model that encompasses all the factors that cause the expatriates to leave the assignment early as well to develop solutions to the problems. This will not only help the multinational corporations to save on costs, but will also ensure that the company and the expatriate benefit from international assignment.

- Description: Analysis of the flora of the Pondoland Centre of Endemism (PCE) recorded 2253 species in the combined checklist of four sites (Port St. Johns, Mkambati, Umtamvuna and Oribi Gorge). Of these 1 % species are endemic to Pondoland, representing 8.7% of the Species, 15% of the genera and 26% of the families of the combined flora. Forty-four percent ofthe combined flora was only recorded from one locality (between 17% and 26% of each flora) and only 12% of the flora was present in all four localities. Of the endemics only sixteen (8%) occurred in all four sites thus each site had its own complement of unique endemics and 21 % endemics were not recorded from any of the four sites. At species level the floras of Mkambati and Umtamvuna were the most similar, followed by that of Umtamvuna and Oribi Gorge. Port St Johns had the least in common with any of the othersites, but more in common with non-neighbours Umtamvuna and Oribi Gorge than with its nearest neighbour Mkambati. Mkambati and Umtamvuna had the largest proportion of PCE endemics and Port St Johns had the lowest. The four sites are quite similar at family level, sharing thirteen families in the top ten family list between them, but much less similar at generic level.

- Description: With the increasing pressures and concerns in education regarding capability, lifelong learning, higher order cognitive skills, transdisciplinary education and so on, educators are seeking fresh ways to teach and new tools to support that teaching. In South Africa, Outcomes Based Education (OBE) has identified critical outcomes (skills) across all subject areas such as problem solving, teamwork, fostering critical thinking etc. as a way of responding to these pressures and concerns. But OBE has been criticised for lacking the necessary tools to develop these critical skills and to promote cross-discipline learning. One innovative way of offering transformative teaching, instruction and learning that may foster the development of these critical skills, particularly those concerned with critical thinking, is by using geographic information systems (GIS) technologies. The scope for using these technologies in secondary education is now being realised for teaching the more generic, cross-discipline skills described whereby students are learning not only about GIS but also with GIS. This realisation provides the opportunity to create flexible, computer-based learning materials that are rooted in authentic, real-world contexts, which aim to enhance the cognitive skills of the students. If these technologies can be used in an innovative way to develop critical outcomes and skills, a model needs to be defined to aid the design and development of learning materials using these technologies for use in schools. The primary aim of this study has been to develop such a model; a model which emphasises the development of real-world learning materials that develop higher-order thinking skills in learners. Another key product of this study is the submission of a comprehensive yet flexible framework for evaluating instructional design models found in the educational literature in order to determine if these design models can be used to develop learning materials forparticular contexts.

- Description: Certain approaches in the discipline Psychology, use the term narrative to describe how they work. Upon investigation one finds that the term narrative is seldom informed from Literary Theory, the background from which it originated. Instead, other disciplines that were also influenced by Literary Theory are invariably used as a means of cross fertilisation, e.g. the work of Geertz from an anthropologist background. Therapists make use of techniques described in the theories in an attempt to come to an understanding of the interactions in the therapy session. Some of the later theories emanating from Literary Theory appear to very useful for opening new ways of research in psychology, especially because some of them already come from an interdisciplinary background. This research attempts to identify useful theories and then apply them within a hermeneutical background in a therapeutical session. Theoretical work on ambiguity, recent research on foregrounding and defamiliarization and also the research in psychonarratology appear to be eminently useful for coming to a deeper understanding of the processes that take place in a therapeutic environment. It is thought that these theories could be of use because they have been 'tested' against the experiences of real readers reading texts. As novels differ from reports and washing lists, therapeutic settings differ from discussions. A novel is a cultivated variant of a report, and a therapeutic conversation is a cultivated version of a chat. These theories then, were applied to a real therapeutic session. The therapists who participated were interviewed on the session and on their reactions to certain 'readings' made by them during the session. The purpose of the interview was to obtain an understanding of their interpretation of what had happened during that session. The questions, reactions, observations and reflections of the session constitute the text of this research. The generated text was then reread from the perspective of each of the theories. The data was collected and interpreted. The interpretation focusses on the therapists 'reading' or understanding of the session and in the process, leads the therapists and researcher to further levels of understanding. In conclusion, it was found that the theories were indeed useful as they were able to point out how certain stylistics of language and situation in the therapeutic session had led to hermeneutic or interpretive processes and also how these processes were perceived or experienced on reflection by the therapists.

A history of the direct taxation of the African people of Kenya, 1895-1973

- Description: This study examines the origin, the manifestation and impact of the direct taxation of Africans in Kenya. While the state had several reasons for imposing taxation on Africans, the basic factor weighed on the need for a definitive source of revenue. For most of the colonial period, this aggregated to about 37½ percent of the total revenues. The thesis shows how taxes were collected from Africans, how this led to participation in the cash economy and how they continually resisted and evaded such taxation. Tax collection was synonymous with colonialism and this was manifested through the central role of chiefs, who used taxes and force to coerce Africans into migrant wage labour. Through taxation policies, legislation and African resourcefulness, migrant wage labour served the needs of a colonial capitalist settler economy. In this way, the colonial state revealed its capacity for dominance, power and exploitation. Evidence has been adduced to show that African taxation was an important factor in Kenya’s administrative, political and economic development. The policy of African taxation, land loss and poor working conditions are remembered as having interfered with African mechanisms for accumulating wealth. One of the main objections of the payment of taxes was the manner of its collection. Those unable to pay were imprisoned or detained while many took to instant flight at the sight of the tax collector. The thesis shows that in spite of all these harsh tax collection methods, peasants remained largely resilient and industrious. The Mau Mau movement was the culmination of various peasant grievances in which the colonial state used steep taxation as a counter-insurgency measure. Kenya’s independence in 1963, however, never altered the predatory nature of the state. Subtle, opportunistic and overt ways continued to be used to extract taxes from the peasants and the working class. It was not until 1973 that the much-hated colonial poll tax that had been renamed as graduated poll tax was abolished and replaced by indirect taxation. Finally, taxation like other colonial legacies has endured and has become one of the most important sources of revenue for the government to manage its fiscal policies.

- Description: This thesis seeks to investigate the possibility that the binary opposition between retributive and restorative forms of justice that structures the discourse on justice is unhelpful and unnecessary, particularly for societies seeking to extricate themselves from violent conflict and towards building peace and democracy. I shall argue for the importance of considering restorative justice as conceptually and historically prior to the possibility of retributive justice rather than the negation of one or the other, as well as advocate the potentially greater transformative power of the values of restorative justice which may provide a constructive alternative to retributive justice in the context of post-conflict peacebuilding.

- 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: Ports are the backbone of the economy of countries endowed with shorelines and they spearhead foreign trade through the importation and exportation of goods to and from their domestic markets. The newly constructed Port of Ngqura will be the outlet for exports of semi-finished and finished goods produced in the Coega IDZ and will also receive raw material to be processed. Its position at the center of the world’s main trade routes, equidistant from American, European and the Pacific Rim regions makes the Coega IDZ the ideal location for any manufacturer adding value to raw materials, components and producing goods bound for the world markets. Traditionally the ports have been developed and operated by the government enterprises. Recently all these are changing in many countries all over the world, with more private participation in the development and operations of the ports. This evolution has entrusted Port Authorities in taking control over port planning, broad regulation of shipping and port operations, applying conventions, laws and rules. South Africa is no exception to these winds of change, hence the adoption of the new port bill in managing all ports in the country. The Port of Ngqura will then serve as a benchmark for all other ports, with a new management structure which will help the port to be efficient. The study addresses the model for the efficient strategic management of the Port of Ngqura. The model looks into placing the Port of Ngqura ahead of its competitors through efficiency in port management and operations. Efficient ports are catalysts, facilitators and attractors of international sea borne trade. Competitive efficiency is achieved by employing the best suited port equipments, facilities and technology to cater for customer’s needs and requirements. A successful port must be able to constantly adopt new roles in order to cope with the ever changing market environment.

- Description: The analysis of jobs and roles is one of the most important techniques in personnel management. It provides the information required to produce job descriptions and person- and learning / training specifications. It is of fundamental importance in organisation and job design, recruitment and selection, performance management, training management development, career management, job evaluation and the design of pay structures. These constitute most of the key processes of personnel management. In terms of the Local Government: Municipal System Act, a municipal manager, within a policy framework determined by the municipal council and subject to any applicable legislation, must - • approve a staff establishment for the municipality ; • provide a job description for each post on the staff establishment ; • attach to those posts the remuneration and other conditions of service, as may be determined in accordance with any applicable labour legislation ; and • establish a process or mechanism to regularly evaluate the staff establishment and, if necessary, review the staff establishment and the remuneration and conditions of service. The overall purpose of the research was to develop a model for the implementation of the Tuned Assessment of Skills and Knowledge (T.A.S.K.) job evaluation system at municipalities, in the Eden/Overberg/Central Karoo region. The research methodology comprised of the following steps: • a literature study on job evaluation and a discussion of the different job evaluation systems with special reference to the T.A.S.K. job evaluation system ; • the development of a model for the implementation of the T.A.S.K. job evaluation system in the Eden/Overberg/Central Karoo region ; and • the empirical data required to achieve the research objective which was obtained by means of postal and electronic questionnaires to employees of the various municipalities in the geographical area that will be covered by this research. The following recommendations are made regarding the data obtained from this study: Firstly, briefing sessions at municipalities must include employees of all levels and the following methods must also be added to the process - • Insert articles in the in-house newsletter ; and • Attach a memorandum to employees’ pay advice, informing them about the T.A.S.K. job evaluation system and later on about the progress of the process. Secondly, all disputes regarding placement must be resolved before employees are allowed to draw up their relevant job descriptions.

- Description: This thesis sets out to obtain an understanding of what it means to be an assessor in higher education, more especially within the Rhodes University context. The concept of assessment, a highly contentious and complex issue, is examined against a background of competing understandings of the nature and purpose of higher education, including the striving for excellence versus the call to more equitable ideals associated with a mass higher education and training system. An overview of salient issues is presented in which both traditional and alternative paradigms of measurement and assessment theory are explored with a view to considering foundational principles upon which sound assessment practice should be based. Specific methods and instruments of assessment are examined with the purpose of evaluating their potential for empowering students as active participants in their own learning and in the assessment process. In a field in which much of the literature seeks improved assessment merely through the administration of increasingly sophisticated assessment techniques, a phenomenological investigation offered a unique way of understanding the meaning assessors make of their practice. Making use of in-depth interviews with five lecturers at Rhodes University the researcher, interacting in a personal manner with people not viewed as experimental objects but as human subjects, assisted participants in moving towards non-theoretical descriptions that accurately reflected their experience. Insights contained in the data were synthesised and integrated into a consistent description of the essential nature of the experience, the primary endeavour of the phenomenologist being to transform naïve experience into more explicitly detailed conceptual knowledge. The essence of how these educators understand themselves as assessors at Rhodes University is perhaps best encapsulated by a considerable sense of agency or initiative on their part. While participants make use of a variety of assessment strategies, they are conscious that assessment cannot be viewed in isolation from other aspects of their teaching and the curriculum. Not only do they make use of different assessment methods but, conscious of accommodating the diverse needs of students, understand their responsibility in terms of providing learning opportunities to assist students in meeting the course outcomes and fulfilling their potential. Rather than allowing pressures from within and outside of the academy to dictate, these lecturers, with significant hard work, courage and a capacity for reflective practice, have embraced the challenges associated with higher education in a state of transition.

- Description: In 1981, a number of reports of death from immune system failure began to cause alarm in medical circles. The Human Immunodeficiency Virus (HIV) was identified as the cause of a condition known as Acquired Immune Deficiency Syndrome (AIDS). To date, there is no cure for AIDS, and as a result it is perceived as the deadliest medical condition of the century. While intensive research remains focused on development of a vaccine, there has been a strong move toward a more preventative approach that is holistic in nature, and encompasses behavioural and social components as being of equal importance. Going hand in hand with HIV/AIDS are Sexually Transmitted Infections (STIs). STIs are increasing around the world and in South Africa at a remarkable rate. Like HIV/AIDS, STIs are also transmitted during sex, more specifically through body contact during sex. Research has identified adolescents as a group that is particularly vulnerable to HIV and STI infection. Life-skills programmes use experiential learning to engage learners and are particularly popular because they empower individuals to make responsible, well thought out decisions based on well developed values and beliefs. There are however, various variables and agents that impact upon the success of HIV/AIDS and STI education. It is therefore suitable to adopt a biopsychosocial approach to underlie a HIV/AIDS and STI life-skills programme. Health models, such as the AIDS Risk Reduction Model, based on this approach should take into consideration important psychological variables to cope with changes in behaviour, as well as prepatory behaviours inclined towards preventing risky behaviour. The Ubuntu Education Fund is a non-government, international organisation that offered a life skills programme in HIV/AIDS, STIs, Rape and Child Abuse to learners in Grades 6 - 9. This study focused on HIV/AIDS and STIs. The sample size was 260 learners from the Nelson Mandela Metropolitan Region. A quasiexperimental one group pre-and post-test design was used to determine if there was a difference between the knowledge of these learners pre- and post- the life skills programme. The results of the study indicate that there was a small increase in knowledge after the life-skills programme intervention. In some schools there was even a decrease in knowledge. This study suggests that the life-skills programme was flawed and that it needs to be reviewed. The implications of these findings are discussed with suggestions for future interventions.

- Description: The plastochron index (PI) is a measure of plant growth reports our findings on PI using the average length of and can be used to determine growth rate, based upon the first pair of leaflets on each node. Early leaflet appearance of successive leaves on the axis of the growth in peas occurs exponentially and the early plant. PI should under ideal growth conditions be a stages of growth of successive pairs of leaflets occur at regular event and should be predictable with a relatively the same relative growth rate. Given that growth of small error of a few hours. PI has been variously leaflets during early development can be measured calculated in peas, and each method reported has had successfully, we propose the use of leaflet growth as a with it a number of problems that do not allow for measure of the plastochron index in peas. Our results reasonable prediction of PI. Internode length varies suggest that plant age is best expressed using the greatly and is dependent upon the variety, which may be plastochron index, which is a measure of the time short- or long-stemmed; thus this parameter is not ideal interval between the initiations of successive events — for determining growth rate or plant age. This paper in the case of peas, of successive pairs of leaflets.

- Description: A networked multimedia system to assist teaching music keyboard skills to a class is described. Teaching practical music lessons requires a large amount of interaction between the teacher and student and is thus teacher intensive. Although there is a range of computer software available for learning how to play the keyboard, these programs cannot replace the guidance of a music teacher. The possibility of combining the music applications with video conferencing technology for use in a keyboard class is discussed. An ideal system is described that incorporates the benefits of video conferencing and music applications for use in a classroom. A design of the ideal system is described and implemented. Certain design and implementation decisions are explained and the performance of the implementation examined. The system would enable a music teacher to effectively teach a music class keyboard skills.

- 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: This study is intended to unpack the current and potential future commuter transport requirements in Kagiso Township within the context of transport planning and the ongoing transformation of the transport sector in South Africa. In order to meet the above challenges, it was felt that an investigation of the socio-economic profile of transport users in Kagiso Township was required, which would be indicative of potential needs and requirements in terms of current and future travel infrastructure. This study is significant, as it considers the impact of socio-economic factors and transport interactions by fully examining the impact of accessibility, urban development patterns, local mobility and planning. Mogale City’s Kagiso Township was selected for in-depth study because it has seen one of the highest urbanization rates in Gauteng Province, with people from all over Gauteng relocating to this suburb, either buying relatively moderately priced housing via mortgaging or, alternatively, trying to gain access to government low-cost housing. The study investigates the connection between socio-economic characteristics of a local population (inter alia, age, gender, household size, and vehicles per household, employment status and income) and their transport requirements (travel demand forecasting), within an urban transport context. Socio-economic characteristics of a population are important in transport demand forecasting because there is a general belief in transport planning that the predisposition to travel and trip generation vary with the characteristics of the traveller. A travel demand forecasting model by Bussière and Rice (1999) is used for the purposes of simulating existing and future travel patterns. The forecasted household mobility and needs of commuters in Kagiso Township are compared with current municipal plans to see whether such plans are realistic and can address existing needs. The evaluation of the current municipal plans is included to test the responsiveness of public policy and practice towards the needs of the affected local community. This evaluation extracted information on whether the relevant municipality has identified the problems and issues affecting the local community of Kagiso Township. In addition, it assessed whether the municipality has identified possible solutions to these problems and issues and whether it has prioritised any projects to improve transportation in Kagiso Township.

- Description: Seaweeds of the genus Plocamium are known to produce a variety of halogenated monoterpenes. In addition to their ecological role as feeding deterrents, biological activities reported for these compounds include antibacterial, antialgal, antifungal and anticancer activities. An investigation of the non-polar extracts of the seaweed Plocamium corallorhiza resulted in the isolation of six known halogenated monoterpene compounds, 4-bromo-5-bromomethyl-1-chlorovinyl-2, 5-dichloro-methylcyclohexane (2.68), 1,4,8-tribromo-3 ,7-dichloro-3, 7-dimethyl-1,5-octadiene (2.67), 8-bromo-1 ,3,4,7-tetrachloro-3, 7-dimethyl-1,5-octadiene (2.66), 4,6-dibromo-1,1-dichloro-3,7-dimethyl-2,7-octadiene (2.64), 4,8-dibromo-1,1,7-trichloro-3,7-dimethyl-2,5-octadiene (2.65) and 3,4 ,6,7-tetrachloro-3, 7-dimethyl-1-octene (2.63) as well as eight new compounds, including five halogenated monoterpene aldehydes. The new compounds were identified by 1D and 2D NMR spectroscopic techniques as: 8-Bromo-6,7-dichloro-3,7-dimethyl-octa-2,4-dienal (2.72), 8-Bromo-1,1,2,7-tetrachloro-3,7-dimethyl-octa-3,5-diene (2.70), 4,8-Dichloro-3,7-dimethyl-octa-2,4,6-trienal (2.74), 4-Bromo-8-chloro-3, 7-di methyl-octa-2, 6-dienal (2 76), 8-Bromo-4-chloro-3, 7-dimethyl-octa-2,4 ,6-trienaI (2.75), 4-Bromo-1,3,6,7-tetrachloro-3 ,7-dimethyl-octa-1,4-diene (2.71), 8-Bromo-1,3,4,7-tetrachloro-3,7-dimethyl-octa-1,5-diene (2.69), 4,6-Dibromo-3,7 -dimethyl-octa-2,7-dienal (2.73). All compounds were screened for antimicrobial activity, brine shrimp lethality and cytotoxicity towards oesophageal cancer cells. Compound 2.68 was toxic to brine shrimp larvae at a concentration of 50 μ/mL. It also showed promising activity towards oesophageal cancer cells with an IC₅₀, of 2 μg/mL.
