- Description: This research paper focuses on developing a model for the integration of the transport operators in the Nelson Mandela Bay area. The motivation for this integration is the Nelson Mandela Bay Municipality’s Public Transport Plan, which has set the goal of developing a new public transport system for the Metropolitan area. This system will integrate the different modes of transport into a single, seamless and scheduled service which will adhere to contractually enforced levels of quality, reliability and safety. In order to achieve this vision, the current bus and taxi operators will need to be unified into a viable and operational entity structure which will provide the required services to the public. The main research problem has therefore been identified as follows: How can the bus and taxi operators in Nelson Mandela Bay be integrated into a single entity, or small number of entities, in order to provide a viable, efficient and sustainable public transport service? This research paper sought to address this problem by conducting a case study of the Nelson Mandela Bay project, which took place over the course of a one year period. The author served as the project manager on the team that was responsible for developing the integration model. Additional research included a study visit to the cities of Bogota and Pereira in Colombia, which have implemented similar transport models, as well as a secondary study focusing on generic organisational integration strategies in existing literature. This paper is fundamentally a qualitative study. In this light, the research data was analysed according to the quasi-judicial method, which was deemed most suitable to the case study format adopted. The findings of the analysis were evaluated, and based on the resultant conclusions, a final integration model was recommended. The fact that this study is based on an actual project that has real world implications and consequences makes the result very relevant, and as such it will serve as a valuable addition to the body of knowledge which can be of assistance to other cities or project teams facing similar challenges in South Africa or even internationally.

- Description: The Printing and Packaging Industry in South Africa has become very competitive over the last decade. Imports and the move towards environmentally friendly packaging have put additional strain on certain sectors of this industry. EH Walton Packaging (Pty) Ltd is one of oldest converters in the industry, established in 1845, and has always been a leader with regards to new technology. It has grown from a small, family business to one of the biggest and most respected in South Africa, but it is still a private company. Due to the rapid growth the shareholders approved a multi-million rand expansion project in 2000. After completion the anticipated increase in shareholder value did not materialize, even though the production facility is always busy. The objective of this research study is to demonstrate to senior management that quality does not end with accreditation of ISO 9001:2000, but that total quality management is invaluable as a business strategy to reach world class manufacturing standards and to sustain organisational excellence. The research will investigate the origins and development of total quality management and world-class manufacturing and extract the most important elements that form the basis of sustainable competitiveness, as well as research done on the reasons why businesses fail. These elements will be further investigated, with special emphasis on the African/South African environment. Research showed that sustained excellence in business and quality is based on customer focus, guided by strategic planning, with leadership at the core, enhanced by philosophy, employee improvement and involvement, and quality assurance. Failure of achieving excellence is best summarized by Deming’s Seven Deadly Sins. The case study approach that was followed to determine the status of total quality elements within the company yielded contrasting results. A number of the “sins” were identified as present in the business strategy; levels of leadership varies from traditional Summary to high performance; understanding of where the company is heading is fragmented; there are no social programs in place and training only concentrates on apprenticeships and not on developing shop floor skills – to mention a few. Surprising is the world-class orientation with regards to customers; but again, this is contrasted with the lack of active customer satisfaction initiatives. The study concludes that although many negative aspects exist and that the prevailing culture does not appear to support change towards world-class growth, there is an element of positive energy among employees. Most of the employees who participated in the study believe that the company has a bright future. It is these attitudes that must be used to drive change, with a clear vision, good strategies and world-class leaders.

- Description: The Swartkops River and Sundays River Estuaries are different in terms of morphology and the level of human impact. Budget models of DIP and DIN were constructed for each estuary at different riverine flow rates, using the Land-Ocean Interactions in the Coastal Zone (LOICZ) protocol. Nutrient dynamics in the estuaries were investigated using nutrient data and the results of the models. The Swartkops River Estuary acted as a sink of DIP and DIN, while being net heterotrophic. The Sundays River Estuary acted as a source of DIP and DIN, while being net autotrophic. Both systems were net denitrifying. The Swartkops River Estuary shows greater anthropogenic impacts in terms of nutrient loads than the Sundays River Estuary. A shift in nutrient concentration trends and system properties occurred between conditions of low and high riverine flow rates. The Swartkops River and Sundays River Estuaries were shown to be ‘outwellers’ of DIN and DIP, while having an important influence on the ratio of DIN:DIP exported to the adjacent ocean. Comparisons with other estuaries suggested that riverine flow into estuaries in the Eastern Cape region may display natural DIN:DIP ratios which are lower than the global average for “pristine” systems. Such ratios would be decreased further by increased water extraction for human activities.

- Description: As the global energy crisis continues to have an impact on developing countries such as South Africa, stakeholders form an increasingly significant role especially around the concerns of development and the impact on the environment. Environmental conflicts have risen to the forefront in many areas in South Africa. Environmental conflicts fall under public disputes, which often occur as a result of human needs. This study is an attempt to explore the environmental conflict surrounding the proposed Nuclear Power station at Thyspunt, Oyster Bay in the Eastern Cape. Stakeholders are an integral part of environmental conflicts, and analyzing interests of stakeholders is vital in understanding environmental conflicts. This explorative study, seeks explore and to describe the interests of homeowners who are one of the key stakeholders involved the environmental conflict at Thyspunt, Oyster Bay in the Eastern Cape. The homeowners are represented by the St Francis Residents/ Ratepayers Association. The researcher conducted extensive face-face interviews with these homeowners. The organizations official documents, minutes of their meetings, letters to the media and various publications in which homeowners expressed their feelings were also made use of by the researcher in order to triangulate findings, as well as for data collection methods. The major themes were constructed from the study include: Security, Trust, Power and the various sources thereof, as well as a need for self-actualization based on values, and a final theme of the positive functions of conflict. The challenges facing the homeowners in terms of human security and environmental impact of the nuclear development are highlighted. Further recommendations for a more in-depth study are also made.

- Description: To constantly add to our understanding of child development, a valid, comprehensive, well-researched measure is needed. The recent revision and standardisation of the Griffiths Mental Development Scales - Extended Revised (GMDS-ER) has necessitated investigations into its psychometric properties. This measure is used to identify developmental delays in children and critical decisions may be made, hence it is imperative that this measure be deemed both reliable and valid. This study aimed to contribute to the broader restandardisation project and focussed on gathering qualitative and quantitative construct-related validity evidence for one of the six Subscales of the GMDS-ER, namely the Eye and Hand Coordination Subscale (Subscale D). An exploratory descriptive method using a triangulation approach was used to explore the construct-related validity evidence of the Eye and Hand Coordination Subscale. A non-random purposively selected sample of 6 experts, who had worked at least 10 years with children assessing and evaluating the domain of eye-hand coordination, participated in a facet analysis to identify the underlying dimensions tapped by the Eye and Hand Coordination Subscale. The sample for the quantitative aspects of this study, the empirical validation of the construct model, was collected as part of the broader restandardisation and represented a stratified sample of 1026 children between the ages 24 months and 96 months from across the United Kingdom and Eire. Three measures, namely a biographical questionnaire, the GMDS-ER and a construct evaluation form were used to gather the qualitative and quantitative data. The qualitative data was analysed by means of a facet analysis and literature control which included examining other tests or subtests that tapped eye-hand coordination skills. The quantitative data was analysed by means of exploratory common factor analysis using oblique (DQUART) rotation in order to verify the qualitatively identified construct model by specifying a one-factor solution for each underlying construct. While literature suggests that eye-hand coordination is multidimensional in nature the facet analysis revealed that the tasks tapped by Subscale D were not tapping complex skills aside from eye-hand coordination. The facet analysis thus revealed that all the items tap the eye-hand coordination of fine motor tasks and that these items could be grouped into two categories, using writing utensils and object manipulation. The results from the factor analysis confirmed that the items on Subscale D have one underlying construct and further exploration confirmed that these items could in fact be grouped into two categories. The coefficients of congruence for SES and gender were satisfactory and thus the construct model was validated across these groups as well. The study has provided extensive qualitative and quantitative evidence for the construct-related validity of the Eye and Hand Coordination Subscale of the GMDS-ER, thus validating its use as a sound measure of eye-hand coordination development in children aged 2 to 8 years. The content coverage however, seemed to indicate that the tasks required do not adequately cover all the facets of eye-hand coordination and some of these item types are tapped by the other Subscales in the measure. Hence, should the Subscale be used as an independent assessment of eye-hand coordination, the eye-hand coordination development of the child would have a narrow focus. In addition, in reviewing the variety of tasks in the two sections for the older and younger child, the researcher noted that while section III tapped a variety of skills, section IV only focused on skills associated with drawing, copying and writing. A review of the age appropriateness of the items and the item analysis results from the revision seemed to indicate that some of the items assessing the older child may need to be revised. Further, the researcher suggested that the revision should consider adding additional dimensions to the tasks assessed. Overall, it is the researcher‟s opinion that this Subscale was not given adequate attention during the revision process and should future revisions occur, the recommendations from this study should be considered.

- Description: This dissertation summarises an analysis and assessment of the application of Quality Management Systems (QMS) by Small, Medium and Micro Enterprises (SMMEs), in the Engineering Manufacturing Sector of the greater Cape Town Metropolitan area. An outline of the existing hypothesis derived from previous international SMME studies related to the adoption of QMS by SMME’s, the management’s understanding of quality principles, the potential business benefits of QMS and the reasons for implementing Quality Management systems are given as background to the study. The dissertation includes a discussion of literature on the state of QMS in SMMEs, in particular, recent international research literature hypothesising that SMME management lack essential QMS knowledge and that, in general, most SMME’s do not have a QMS and that SMMEs only implement a QMS as a result of contractual pressures / requirements. Also reported are the results and findings of a survey conducted to test the validity of the existing hypotheses amongst a representative sample of Engineering Manufacturing SMMEs registered with the Cape Regional Chamber of Commerce and Industry in the Western Cape. Results of the survey indicate that almost 90 percent, of the companies surveyed had some type of Quality management System, the only two companies that reported not having a QMS, were companies classified as “Micro”, in terms of the National Small business Act. Analysis of the response to the survey concludes that, in general, more than 80 percent of Engineering SMMEs in the Manufacturing Sector have adopted a QMS based on ISO 9001 and that, on average, their management have a medium to high level of understanding of QMS and the associated business benefits. It is also apparent from survey responses, that companies classified as “Micro” in terms of the Small Business Act of 1996, do not see the need for a formal QM system as the owners of these companies consider them too small for a formal QMS. Instead they take direct ownership of their service and product quality in the face of the customer.

- Description: It is important to the survival of the Africa Penguin (Spheniscus demersus) population that breeding at the nest site is successful and that large numbers of chicks are fledged into the breeding population. Nest distribution on Bird Island is not random and locality preferences for breeding exist. Although it seems that sufficient area exists on Bird Island for penguin nests, it can hardly be considered as suitable to optimise breeding. During prolonged heat conditions, breeders relocated to nest sites that were sheltered. Nests that were below ground in burrows was the only habitat that did not suffer nest desertion whilst all the other habitat types (including those that were sheltered) experienced 2-3 fold declines in nest numbers. Nests density and the selection of suitable nest sites are significantly influenced by the stage of breeding that the majority of birds are in, yet nests that are shaded, well-ventilated and protected seem to be the most preferred sites for breeding. Adults that attempt to breed are considered then to be in a healthy condition and will usually lay a double clutch (Randell 1983). The frequency of double clutches being laid during the peak breeding attempt was significantly higher compared to the replacement one. Breeding failure was fairly similar to breeding success during the incubation stage for nests with double clutches however, was substantially higher in single clutches. The growth rate of chicks was best fit to the von Bertalanffy growth curve in 90 percent of the cases. The overall growth rate of chicks from double broods was faster than from single broods, however was not significant. A-chicks maitain a high growth rate until they fledged. Yet, the sibling B-chick recorded the lowest growth rate of the successfully fledged chicks and up to until day 30 recorded a similar weight to those chicks that failed to fledge. Contrary to findings of Randall (1983), chicks from single broods delayed fledging, recorded lowest overall growth rates and experienced the greatest weight loss of all groups, yet fledged successfully. In order for chicks to fledge successfully, they needed to obtain a weight of 1060 g before day 30.5 in their growth cycles to avoid death due to startvation later on. Single chicks that are raised from a double cluth, fledged more other than chicks raised from a single clutch. Unfit or ill-adapted breeders that are marginal in the capabilities of raising offspring, already manifest in a small clutch size and offspring unable to obtain adequate weights during the initial stages of growth.

- Description: Most students are adolescents and young adults, a group characterized by a new-found sense of independence, experimentation with sex and sometimes drugs and a feeling of invincibility (Gayle, Richard, Keeling, Garcia-Tunon, Kilbourne, Narkunas, Ingram, rogers and Curran, 1990:1538). These behavioural, developmental and environmental issues may contribute to premature morbidity, mortality and reduced quality of life for university students (Patrick et al., 1992:260). The ages of staff on the other hand range from young adults to retirement age. The types of health problems that exist among staff who use the campus health service include First Aid treatment on site for injuries on duty and more chronic health problems such as, for example, hypertension and diabetes mellitus. To date there is very little evidence as to whether or not the healthcare needs of students and staff are being met comprehensively or whether the practitioners rendering the service are knowledgeable and complying with the PHC norms and standards developed by the department of Health’s Quality Assurance Directorate. The lack of such empirical data can contribute to misconceptions and hamper the management of public health problems experienced in SA, for example sexually transmitted infections and the transmission of HIV. Thus the purpose of this research was to develop a model that would assist registered nurses employed at a higher education campus health service in the Western Region of the Eastern Cape Province to render a healthcare service relevant to the healthcare needs of the students and staff on campus.

- Description: Remarried families are no longer the exception in society. Statistics reveal that this type of family structure is increasing. The need for family resilience research in varying family forms has been highlighted. Given the distinctive structure of the remarried family, there are specific dilemmas and challenges that need to be resolved on the journey towards family integration. Despite these challenges, many families benefit from their new family structure and show marked resiliency and ability to adapt. South African family resilience research is scarce. This study aimed to identify, explore and describe the resiliency factors that enable families to adjust and adapt as a result of being a stepfamily. The Resiliency Model of Family Stress, Adjustment and Adaptation (McCubbin, Thompson, & McCubbin, 2001) was used to conceptualize level of adaptation. Participants consisted of both adults and adolescents, in order to gain perspectives of adapting to a remarried family from differing individual family members’ stages of development. Participants consisted of 19 parents and 16 adolescents, equaling a total of 35 participants. Triangulation was employed, with an exploratory, descriptive approach. A biographical questionnaire with an open-ended question, in conjunction with a number of structured questionnaires were used to gather the data. These questionnaires were: The Family Hardiness Index (FHI), the Family Time and Routine Index (FTRI), the Social Support Index (SSI), the Family Problem-Solving Communication (FPSC) Index, the Family Crisis-Oriented Personal Evaluation Scales (F-COPES), the Relative and Friend Support Index (RFS), and the Family Attachment and Changeability Index 8 (FACI8). In this study the FACI8 was used as a measure to determine the level of family adaptation. Non-probability purposive and snowball sampling techniques were used. Descriptive statistics were used to analyze the biographical information. Correlation and regression analysis was used to analyze the quantitative data, and content analysis was used to analyze the qualitative data. The results of the quantitative component of the study indicated that there were three significant positive correlations with the FACI8 for both adults and adolescents. These variables were family hardiness (measured by the FHI), family problem solving communication (measured by the FPSC), and family time together and routines (measured by the FTRI). The Social Support subscale of the F-COPES showed a positive correlation with the FACI8 for the adults. The results of the qualitative component of the study revealed that various common themes emerged between the adult and adolescent participants’ responses. These common themes were spirituality; boundaries; respect, love, understanding, compassion and acceptance; communication; flexibility and tolerance; time together, bonding, and routines; and social support. There were four remaining themes that the adults identified as important factors helping them manage being part of a stepfamily. These four remaining themes were equality; forgiveness and acceptance of the past; commitment and being positive; and financial support. The value of the research was discussed. Finally, limitations of the study were discussed, and suggestions were made for future research involving remarried families.

- Description: New Caledonia, an archipelago situated in the South-West Pacific Ocean has a very high biodiversity of which many flora and fauna species are endemic, and is therefore considered as one of the world hotspots for the biodiversity conservation. Sclerophyll forests, one of the five main vegetation types occurring on the island are mainly threatened by anthropogenic activities. Rusa deer (Cervus timorensis russa) were introduced into New Caledonia from Java in 1870. They have colonised all the biotopes of the main island, and represent one of the major threats to the New Caledonian sclerophyll forests. Currently, there is a lack of management tools to monitor the trends of rusa deer in New Caledonian sclerophyll forests. To test monitoring methods for use as management tools, six sclerophyll forests study sites were studied using direct census methods (i.e. spotlight count and drive count), indirect census methods (i.e. faecal standing crop method) and three indices (i.e. the faecal pellet groups index, the browsing index and the antler rubbing index). The faecal pellet groups index is based on sampling pellet groups in plots along transects. To ensure reliable data collection with a coefficient of variation of the mean number of intact faecal pellet groups per plot per transect of less than 20 percent, my study indicated that 15 plots per transect and 20 transects per sites should be sampled in New Caledonian sclerophyll forests whereas previous studies conducted in New Zealand indicated that a minimum of 25 plots per transect and of 18 transects per site should be sampled. The advantages of reducing the number of plots per transect and of transects per site is that it reduces the expenses (e.g. time, finance) and the bias due to data collection (e.g. fatigue, boredom and visual activity) which will improve the precision of the data recorded. Estimates of rusa deer density obtained from the census methods were not correlated (r = - 0.425, df = 4, P = 0.401) due to my small sample size. The reliability of these estimates is questionable because of biases. Previous publications have shown that biases are difficult to avoid when using direct census methods and that it is difficult to estimate the size of animal populations with accuracy and precision. The faecal standing crop method was subjected to bias because the estimation of the decay rate and the defecation rate were unreliable. These methods were not recommended for rusa deer management in New Caledonian sclerophyll forests. Of the three indices tested, the faecal pellet groups index and the browsing index based on unpalatable browse species were the most reliable as the confidence intervals of these two indices were small (i.e. from ±0.08 to ±0.11 for the faecal pellet groups index; from ±0.04 to ±0.27 for the browsing index of unpalatable browse species), and they also showed significant correlations with a subjective ranking of the rusa deer density based on expert knowledge (rs = 0.829, df = 4, P = 0.042 and rs = 0.829, df = 4, P = 0.042 respectively). These two indices appear to show the most promise for use as management tools, as they could reliably track local variations of rusa deer densities on the sclerophyll forests. These two indices could be used by wildlife technicians in New Caledonia to establish management plans of rusa deer populations which rely on participative management involving the stakeholders (e.g. hunters, forest managers, local communities). We believe that the faecal pellet groups index and the browsing index could be useful to monitor rusa deer populations in New Caledonian sclerophyll forests, and meet conservation and hunting objectives of the local population and authorities. Management tools such as culling and hunting operations will be implemented in New Caledonian sclerophyll forests where monitoring of indices I recommended show an increase in the deer population. Stakeholders will be involved in the implementation of the monitoring tools (i.e. indices) and of the management tools (e.g. culling and hunting operations, fencing) but also in decision making for the management of the rusa deer in New Caledonian sclerophyll forests.

- Description: The research study was conducted to cover the Buffalo City Municipality (BCM) retail industry with direct emphasis on the supermarket industry. The research problem is as a result of the retail businesses in the BCM that continue to consider that if they have large data warehouses with masses of customer information, they have all what it takes to run a profitable business. Their failure to understand the organizational implications of moving towards a customer-centric approach often results in high costs from bad customer service and handling of customer complaints. The main problem was stated and sub-problems introduced from the main problem to address them by way of qualitative and quantitative research. Related literature was reviewed on Redefining the Customer, Customer Satisfaction and Customer Relationship Management and a Customer Management Model was proposed. During empirical survey, a questionnaire based on literature reviewed was designed for the survey. A pilot study was conducted to identify and rectify problems and shortcomings relating to the questionnaire. The pilot study indicated that the data likely to be collected will address the main and sub-problems of the research. A total of thirty five questionnaires which contained closed-ended and open-ended questions were distributed to the population sample as selected. Results of the study were critically analysed and interpreted quantitatively and qualitatively by means of tables and discussion for the development of an Integrated Model for managing customers. The analysis of the study which was based on the literature reviewed and the findings from the empirical survey were concluded to present a solution to the problem. In view of the shortcomings identified by the literature review and integration thereof with the results of the empirical study, an Integrated Customer Management Model was developed.

- Description: As part of CSIR Biosciences’ interest in aroma chemicals, the processing of crude sulphated turpentine (CST) into high value aroma products was investigated. The primary target product, linalool, was obtained from a mixture of α- and β-pinene in four steps. It can be transformed into a wide range of high value added aroma chemicals. Isomerisation of linalool in the presence of a transition metal catalyst furnishes geraniol and nerol. The scientific work described in this report was part of a bigger project aimed at developing innovative processes to manufacture aroma, flavour & fragrance chemicals through beneficiation of industrial waste streams and other raw materials, available locally from the Forestry, Paper & Pulp industries. The evaluation of a process for the preparation of precursor aroma, flavour & fragrance compounds, in particular geraniol and nerol, from locally available raw materials and industrial waste streams, was investigated. Preparation of geraniol and nerol from linalool (ex α-pinene stream) was investigated using acids or organometallic complexes as catalysts for the corresponding isomerisation reaction. The investigation was conducted in an effort to find a less costly process utilising milder conditions than via the conventional cleavage of β-pinene to myrcene under extreme pyrolysis conditions (>650°C). The transformation of linalool to geraniol/nerol using mineral acids was found to be dominated by secondary reactions such as dehydration and cyclisation, resulting in poor product selectivities and yields. On the other hand, organometallic complexes, in particular vanadium-based complexes (e.g. (OV(OBu)3) produced satisfactory results in the preliminary assessment (conversion of 79.8 percent and selectivity of 98.3 percent). A set of statistically designed experiments was carried out on the (VO(BuO)3 + [(Bu)4N+]OH¯) catalyst system where three variables were tested, i.e. substrate concentration, temperature, and catalyst loading. The selected model for conversion was significant with the “Probability > F” being < 0.0001. The most important contributing variable to the model for conversion was temperature i.e. 83.9 percent. Temperature was still the most important variable for the selectivity response at 65.0 percent contribution level. The response surface generated for the selectivity response was flat indicating a robust method within the parameter range selected.

- Description: With the financial crisis of 2008 and more retirement funds and insurance companies entering the hedge fund industry, the safety of investor assets has become vital. According to a worldwide study by Kundro and Feffer (2002:42), operational risk factors account for almost half of hedge fund failures. The issues that underlie the operational risk factors relate to valuation of the fund’s assets and liabilities. Unless certain valuation practices become more widespread, hedge funds face a potential crisis of confidence with institutional and high net worth investors (Kundro and Feffer, 2002:42). Despite the improvements made by administrators to deal with the complexities of hedge fund investments, the accuracy of some valuations remains open to question (McVea 2008:135). Hedge fund manager inputs into valuations compromise the degree of independence exercised, particularly with regard to complex and/or illiquid instruments. The perception that administrators lack the required technical expertise to value complex and/or illiquid assets exacerbates the issue of administrator’s reliability to provide independent valuations. Therefore, the reliance on administrators to guarantee the quality of valuations of complex instruments is in question. The aim of the study was to identify ways to improve operational risk management practices, particularly valuations, in hedge funds through identifying ways of promoting effective functioning of independent third-party administrators. This was achieved through a case study approach using a South African leading administrator, Investment Data Services, as the object of study. The literature highlighted the changing functions of administrators, the challenges facing them and ways of addressing those challenges. The empirical study measured the extent of IDS’ valuation practices in managing operational risk in hedge funds. Four key members of IDS’ management team and one hedge fund manager with considerable insight were interviewed. The data obtained was then reduced into meaningful results. The empirical findings were compared with the theory provided in the literature scrutiny to identify ways of improving the valuation function. The conclusion was that the challenges faced by the administrator were addressed through proper independence, consistency and transparency of the valuation process. A crucial cog in IDS’ wheel is the employment of staff with the required technical skills to understand complex financial instruments. In addition, investment in advanced systems and technology is important in managing the risks involved. Consequently, IDS’ valuation practices can be used as template for other administrators in their efforts to manage the operational risks in hedge funds.

- Description: The aim of this research project is to conduct an evaluation on the implementation of gender mainstreaming in South African government departments, with specific reference to the Department of Justice and Constitutional Development (DoJ&CD) and the Department of Foreign Affairs (DFA). The research project is based on the hypothesis that despite the existence of a National Gender Machinery, Gender Focal Points (GFPs) face numerous challenges in implementing gender mainstreaming, due to various internal and external factors. Based on the two case studies, the research project concludes that despite a strong commitment from government, GFPs still face challenges in effectively implementing gender mainstreaming. This is due to a lack of accountability, an understanding of the concept of gender mainstreaming, as well as a lack of resources. Furthermore, systemic weaknesses within the National Gender Machinery are exacerbating the challenges faced GFP

- Description: The Heads of State and Government Implementation Committee (HSGIC) of the New Partnership for Africa’s Development (Nepad) acknowledged and recognised the centrality of good governance within the context of the African Peer Review Mechanism (APRM), an innovative mechanism acceded to by member states of the African Union (AU) as a self- monitoring mechanism for good governance. South Africa is one of the countries which acceded to the APRM in 2003. Accordingly, South Africa appointed a National Governing Council (NGC) under the chairpersonship of the Minister of Public Services and Administration as the focal point to develop a strategy to manage the national APRM process. The NGC was constituted of business, the disabled, civil society, churches, trade unions, government and women’s coalitions thus ensuring all relevant stakeholders are represented. As part of South Africa’s country assessment, questionnaires dealing with the four core thematic areas of the APRM were sent through to the public by community development workers. In addition, four technical assessment agencies were appointed to assist in conducting research on the four thematic areas. The primary objective of this study is to examine the theoretical approach to the study and the African Peer Review Mechanism’s contemporary relevance to South Africa, its intended beneficiaries and an assessment of South Africa for the period 2006. The study revealed that Proportional Representation (PR) and floor-crossing have an impact on the sustainability, relevance, long term development, vibrancy and profundity of constitutional democracy in the country. Clearly, since the dawn of the democratic dispensation in South Africa the electoral system introduced is such that it had to take into account the challenges the country faced during the apartheid system of governance. In this context, enough space for free political competition in the country was created. On the basis of the findings of the study, it is patently clear that the time allocated for the CSAR was minimal and the country should have been given at least two years so that the self assessment could have been extensively done. On the issue of HIV and AIDS and its relationship to socio-economic conditions, it was revealed that the country has a lot to do in this regard. The debilitating effect that HIV and AIDS has on the lives of the citizens requires clarity of policy and strategy, consistency in public communication and the need for sustained partnerships amongst all relevant stakeholders. At another level, there was a call for a basic income grant although government does not necessarily support it. Based on the research findings above, a new research area outlined under recommendations can be conceptualized for further research and it requires some attention.

- Description: Design changes due to lack of constructability, cost overruns, delays and dissatisfied clients are but a few problems experienced in construction due to poor management of the design processes. Increased problems, challenges, demands and continuous criticism of the architectural profession has led to increased demand for research into the improvement of design processes. The aims of this research were to determine the adequacy of design management processes used by Eastern Cape (EC) architectural companies and compare these with the design management processes used in manufacturing in order to establish practices, theories, principles, technologies and deliverables that can be transferred from the manufacturing into the construction to improve efficiency of architectural design management. The quantitative research approach was implemented for this research, the questionnaire was designed to acquire primary, factual and attitudinal data from EC architectural companies and secondary data were acquired through a literature review. The results revealed that design management processes, continuous improvement philosophies, lean principles, and Information and Communication Technology (ICT) used by EC architectural companies are not similar to those used in manufacturing. Therefore EC architectural companies could increase their efficiency by adopting some of the design management processes, ICT, continuous improvement philosophies and lean principles originating from the manufacturing industry.

- Description: The Republic of South Africa became a democratic country in 1994 after the historic democratic elections. This year also marks the year when South Africa’s first democratic parliament was convened. The Constitution of the Republic of South Africa Act (no. 108 of 1996) was enacted in 1996. This Constitution provides for the creation of the three spheres of government, namely, the national level, which deals with matters of national importance, the provincial level, which deals with matters of provincial importance, and the local level which deals with matters of local importance. Section 152(1) (e) of the above-mentioned Constitution stipulates that the object of local government, amongst others, is to ensure the involvement of communities and community organizations in the matters of local governance. Section 73 of the Municipal Structures Act (no.117 of 1998) also requires municipalities to establish ward committees in a manner that seeks to enhance participatory democracy at the local level. Municipalities are established in terms of Section 12 of the Municipal Structures Act (no. 117 of 1998), wherein Members of Executive Councils (MEC’s) may, by notice in the Provincial Gazette, establish a municipality in each municipal area which the Demarcation Board demarcates in the province in terms of the Municipal Demarcation Act (no. 27 of 1998). Sections 7 and 8 of the Municipal Structures Act (no. 117 of 1998) further stipulate the categories of municipalities as A, B and C. Category A is a metropolitan municipality with wards and ward committees. B is a local municipality characterized by the existence of wards and ward committees to enhance public participation. C is a district municipality, whose responsibility is to support local municipalities within its area of jurisdiction so that they are self sufficient and can manage their own affairs. This study focuses on the Kouga Local Municipality, which is a Category B Municipality as promulgated by the then MEC for Housing, Local Government and Traditional Affairs, Honourable MEC S. Kwelita in the Provincial Gazette (Gazette No. 1537) dated 23 May 2006. The scenario above indicates that in the Kouga Local Municipality, ward committees are supposed to play a critical role in public participation. The study seeks to assess their role and to establish whether or not the ward committee system is effective in this regard. It is common knowledge that, whilst various pieces of legislation are clear in terms of what the role of ward committees should be, the question remains whether there is any adherence in municipalities to ensure that they fulfill their role in public participation, and hence the study.

- Description: The investigation has been focussed on the synthesis and characterisation of camphor-derived chiral auxiliaries that incorporate two camphor skeletons and an evaluation of their stereodirecting potential in ester α-benzylation reactions. Two regioisomeric camphorquinone-derived monoketals were synthesised and identified by 1D- and 2D-NMR, and X-ray crystallography. The stereo-directing potential of the alcohols that resulted from reduction of these ketones as chiral auxiliaries in the alkylation of carboxylate ester derivatives has been studied. The diastereoselectivities shown by NMR spectroscopy range from 14- 30 % d.e. for (1R,2 S, 3R) -2 ,2-[ (1R, 2 S, 3R) -bornane-2,3-dioxy] - bornan-3-ol and 68-74 % d.e. for (1R, 2S ,3R) -3 ,3-[ (1R, 2S ,3R) - bornane-2, 3 -dioxy]bornan-2-ol with selectivities that correlate with the size of the alkyl group in the ester moiety. Trapping of the enolates generated from (1R, 2S ,3R)-2, 2 -[(1R,2 S, 3R) -bornane- 2,3-dioxy]bornan-3-yl propanoate afforded both E- and Z-silyl ketene acetal derivatives in the ratio of 64:36 confirming the formation of both possible enolate structures during enolization. Chiral auxiliaries containing a hemiaminal ether blocking group as well as two chiral alcohols containing monothio-ketal blocking groups have also been synthesised. α-Benzylation of their corresponding propanoate esters afforded the alkylated product with disappointingly low diastereos electivities. Asymmetric reduction of α-keto esters attached to (1R, 2 S, 3R) - 2,2- [ (1R,2 S, 3R) -bornane-2, 3 -dioxy]bornan-3-ol and (1R, 2S ,3R) - 3,3- [ (1R,2 S, 3R) -bornane-2, 3 -dioxy]bornan-2-ol with metal hydrides proceeded with selectivities of up to 30 % d.e. Modelling of the keto ester derivatives at DFT levels provided useful insights into possible conformations adopted by the two α-keto esters and hence the preferred face of attack by metal hydride during reduction.

- Description: Effective, efficient and expeditious resolution of labour disputes plays a crucial role in terms of the realization of one of the primary objectives of the Labour Relations Act (hereinafter referred to as “the Act”) which is the achievement of labour peace. Although there is no proper definition of a dispute offered by the Act, there are several elements raised by authors within the labour relations and labour law fields which constitute a dispute. Two types of disputes are discussed, namely disputes of right (emanating from entitlement) and disputes of interest (based on demands not provided for, and these are also known as disputes based on matters of mutual interests). Labour relations in South Africa has a history that is tarnished by segregation and dualism, where there was a system of labour relations and labour statutes for all races (except for Africans). The first statute dealing somewhat comprehensive with labour disputes, the Industrial Conciliation Act, did not apply to Africans. This situation (exclusion of Africans) prevailed until the early 1980’s. Therefore, although the apartheid system was legislated in 1948, its segregation practices based on race existed long before 1948 and also extended to the workplaces. The turning point in the labour relations arena in South Africa was the appointment of the Wiehahn Commission. As a result of the recommendations by this Commission, African Workers were for the first time included in labour legislation. So, of great interest is the fact that African Workers attained labour rights before the demise of the apartheid system. The birth of the Act with its dispute resolution fora like the Commission for Conciliation, Mediation and Arbitration (hereinafter referred to as “the CCMA”), Bargaining Councils, Labour Court and the Labour Appeal Court, revolutionized dispute resolution in the country. However, there are some challenges that have emerged even within the new system. Prior to 1993, labour relations in the public service, simply just did not exist. This was mainly due to the fact that the public service was excluded from mainstream legal framework governing labour relations. The State was very much in control of what was happening with regards to employment relations in the public service. There were some structures developed for engagement with the State like the Public Service Commission (PSC) which was politicized to push the agenda of apartheid, Public Servants Association (PSA) for White Public Servants, Public Service Union (PSU) for Indian Public Servants and Public Service League for Coloured Public Servants. There was no structure established for African Public Servants though. Nevertheless, these established structures were useless. One of the recommendations of the Wiehahn Commission was the inclusion of public servants within the mainstream labour relations framework and this was never pursued by the then government. It took the wave of strikes in the early 1990’s for the Act to be extended to the public service. Even with the inclusion of public service within the scope of the Act, there are still challenges pertinent to the public service. Central to these challenges is the problem of fragmentation in terms of approach regarding dispute resolution and the fact that there are too many pieces of legislation dealing with dispute resolution. This situation has also resulted in a jurisdictional debacle within the public service. Also, there is a huge challenge in terms of dealing with abscondments / desertion within the public service. In terms of the way forward, there is an initiative to streamline the public service. In this regard, there is a Draft Single Public Service Bill and also the Public Service Amendment Bill.

- Description: Background: In recent years the incidence of Attention Deficit/Hyperactivity Disorder (ADHD) has increased. Objectives: The primary aim of the study was to determine the treatment of children and adolescents diagnosed with ADHD in South Africa and more specifically the Eastern Cape. Methods: The study consisted of two parts, a retrospective drug utilisation study and a questionnaire survey. The drug utilisation study was conducted on chronic medication records of a private sector medical scheme administrator and contained records from 1994 to 2006. A total of 42 250 records representing 8 274 patients and 4 001 families, were analysed. The questionnaire survey was conducted in the Eastern Cape. The questionnaires were distributed by responsible pharmacists to parents of children receiving medication for the treatment of ADHD from his/her pharmacy. Fifty one completed questionnaires were analysed. Results: The average age of patients in the drug utilisation study were 14.28 (SD = 5.50) years. Males represented 77.37 percent of patients. Ritalin® 10 mg was the most frequently prescribed methylphenidate-containing product, followed by Ritalin® LA 20 mg. The two most frequently prescribed active ingredients apart from methylphenidate were fluticasone and budesonide. The two most common comorbid conditions were allergic rhinitis and asthma. The average age of patients in the questionnaire survey was 10.26 (SD = 2.51) years. Males represented 73.58 percent of patients. A third of patients had relatives previously diagnosed with ADHD. Ritalin® 10 mg was the most frequently prescribed methylphenidate-containing product. Conclusion: ADHD is a complex life-long disorder. It does not only affect the child diagnosed with the disorder, but also has effects on the family, schooling system and peer relationship. Therefore, more studies regarding the incidence and treatment of ADHD need to be conducted in South Africa.
