- Description: Insider trading is one of the practices that (directly or indirectly) lead to a host of problems for example inaccurate stock market prices, high inflation, reduced public investor confidence, misrepresentation and non disclosure of material facts relating to securities and financial instruments. Again it reduces efficiency in the affected companies and eventually leads to economic underperformance. The researcher observed that the South African insider trading regulatory framework has some gaps and flaws which need to be adequately addressed to ensure efficient and stable financial markets. Therefore, the aim of this research is to provide a clear roadmap for an effective, efficient, adequate and internationally competitive insider trading regulatory framework in South Africa. In order to achieve the above stated aim, the historical development of the regulation insider trading is critically analyzed. The effectiveness and adequacy of the Insider Trading Act, 135 of 1998 is also discussed. Furthermore, the prohibition of insider trading under Securities Services Act, 36 of 2004 is explored and analyzed to investigate its adequacy. The role of the Financial Services Board, the Courts and the Directorate for Market Abuse is also scrutinized extensively. Moreover, a comparative analysis is undertaken of the regulation of insider trading in other jurisdictions of United States of America, Canada and Australia. This is done to investigate any lessons that can be learnt or adopted from these jurisdictions. The researcher strongly contends that having the best insider trading laws on paper alone will not cure the insider trading problem. What is required are adequate laws that are enforced effectively in South African courts. Therefore an adequate insider trading regulatory framework must be put in place to improve the efficiency of South African financial markets, to maintain a stable economy, combat misrepresentation and non disclosure of material facts in transactions relating to securities. The researcher has attempted to state the law as at 31 August 2007.

- Description: This study critically analyzed land redistribution and economic empowerment of farm workers in the Stellenbosch agricultural area. Past socio-economic and political policies have resulted in a racially skewed and inequitable distribution of land as well as overcrowding, overstocking and poverty in the countryside. It has become imperative that fundamental change is brought about in order to improve economical opportunities of all South Africans to access land for beneficial and productive use. Land reform, as the central thrust of land policy, is not only part of the effort towards the creation of equitable land distribution, but also of national reconciliation and stability. This study analyzed the notion of economic empowerment of farm workers. It looked at historical overview of the evolution of politics in South Africa and contemporary legislative framework pertaining to land redistribution and farm workers in the Western Cape. A case study of Bouwland farm in the Stellenbosch agricultural area was used as an example of how land redistribution can contribute to economically empower farm workers.

The inauguration of the Stephen Bantu Biko Building is, therefore, a good occasion for “a critical appreciation of where we” as Rhodes University “come from”. Credit is due to the pioneers who 104 years ago created Rhodes; to those who, under difficult and financially trying conditions, steered its subsequent development; to those who oversaw its maturation from a University College under the auspices of the University of South Africa to a fully-fledged University in 1951, and to the subsequent generations that energetically toiled to produce the Rhodes University of today’s enviable reputation.

- Description: The larval fish assemblage in the shallow, nearshore region of a proposed marine protected area (MPA) in eastern Algoa Bay, temperate South Africa was investigated. Current velocities and direction and the swimming abilities of late-stage larvae were further assessed to determine potential larval movement to and from the MPA. In total, 6045 larval fishes were collected along two depth contours (~5m and ~15m) in the shallow nearshore of eastern Algoa Bay using stepped-oblique bongo net tows, twice per season for two years (March 2005 – January 2007). These larvae represented 32 families and 78 species. The Gobiidae, Cynoglossidae, Clupeidae, Engraulidae and Sparidae were the dominant fish families. Catches varied significantly between seasons peaking in spring with a mean of 64 larvae/100m3. Preflexion stage larvae dominated catches (75%). All developmental stages of Diplodus capensis, Engraulis capensis, Heteromycteris capensis, Sardinops sagax and Pomadasys species were found in the study area. It appears that these species use the shallow nearshore as a nursery area. Analysis of 12 months (May 2006 – May 2007) data from a bottom-moored Acoustic Doppler Current Profiler within the study area showed that offshore south eastward (39%) and onshore north westward currents (33%) dominated. The south westward current (15%) and north eastward current (12%) occurred less frequently. Current velocity decreased with depth in the nearshore, with a mean velocity of ~29 cms⁻¹ recorded at a depth of 4 m and a mean velocity of ~11 cms⁻¹ recorded at a depth of 14 m. Understanding the dispersal and movement of marine fish larvae in coastal habitats requires knowledge of active swimming abilities. The critical speed and endurance swimming of late stage larvae of two common inshore species occurring in the study area, Diplodus capensis and Sarpa salpa (Family Sparidae), were measured in a laboratory swimming chamber. The mean U-crit value for D. capensis (18.6 cms⁻¹) was similar to that of S. salpa (18.0 cms⁻¹), whereas mean endurance (km swum) was greater in S. salpa (8.4 km) than D. capensis (5.9 km). These swimming abilities exceed the average current velocities observed in the shallow nearshore providing larvae with the ability to greatly alter their passive dispersal trajectories and ultimately influence their distribution in the nearshore.

The role of the judiciary in protecting the right to freedom of expression in difficult political environments: a case study of Zimbabwe

- Description: The right to freedom of expression is with no doubt one of the most important rights in all democratic societies. The southern African sub-region is however lacking when it comes to the protection of this right. There are either highly repressive laws which result in the right being practiced but to a limited extent. In other cases the media is owned by the elite in society which results in the majority not being represented in the independent media and at the same time, the public media is often abused by the governing elite. The scene is therefore that both the public media and private media are representative of the elite. The research seeks to explore the protection of human rights, particularly the right to freedom of expression in politically volatile environments. The research focuses on Zimbabwe but comparative analysis has also been drawn with other jurisdictions moreso South Africa. It is important to note that Zimbabwe has ratified both the International Covenant on Civil Political Rights and the African Charter on Human and Peoples’ rights both of which protect the right to freedom of expression. It is however not enough that states ratify international and regional instruments without domesticating the instruments at the national level. The domestication of the international and regional instruments is meant to ensure that individuals enjoy these rights. Freedom of expression is highly volatile in Zimbabwe. The legislature has been accused of taking away the right which has been granted to citizens by the Constitution through its highly repressive laws. The Access to Information and Protection of Privacy Act (AIPPA), the Public Order and Security Act (POSA), and the Official Secrets Act are some of the laws which have been put under spotlight in Zimbabwe. There is therefore a conflict between the legislature, the press and individuals in Zimbabwe. In Zimbabwe like many democratic states, there is separation of powers between the legislature, the executive, and the judiciary. The legislature is the decision making structure that enacts policies in their capacity as representatives of the people; the judiciary is the mediating body that adjudicates decisions between the organs of state as well as between those organs and individuals and the executive enforces decisions. The findings of the research are that despite the ratification of international and regional instruments dealing with the right to freedom of expression and the protection of the right to freedom of expression in the constitution, there still exist repressive laws in Zimbabwe which to a great extent limit the right to freedom of expression. These laws in light of the prevailing environment in Zimbabwe are often used to deprive citizens and journalists of information and their right to freedom of expression. The judiciary finds itself in a difficult position as the executive does not comply with its rulings. The independence of the judiciary, in light of the environment is also compromised by the threats to the judges, the appointment process and ‘gifts’ given to the judges for example, farms. The research analyses the history and theories of freedom of freedom of expression in Zimbabwe, the laws regulating the right and the case law dealing with this right. Finally there is a comparison between Zimbabwe and South Africa and conclusions and recommendations are made based on the discussion in the dissertation. Among the recommendations is that civil society should be involved in educating individuals especially journalists about the right to freedom of expression. Further, the judiciary should also take a more proactive approach in the protection of the right.

Socio-economic impact of the participatory and conventionally implemented irrigation and livestock development projects: a case of Beitbridge and Mberengwa Districts of Zimbabwe

- Description: The purpose of this study was to evaluate the impact of participatory and conventional approaches to livestock and irrigation project implementation in Zimbabwe’s Beitbridge and Mberengwa districts. The conventional livestock projects performed better than the participatory. Despite the breed for the participatory livestock projects being unsuitable for the environment, the farmers failed to utilize the drugs and surplus funding set aside for replacement of dead cattle. Farmer training was found to be of paramount importance in the establishment of the livestock projects in spite of the participatory approach used for the implementation of the projects. Also the technical backup and support for the livestock project beneficiaries is important to ensure early rectification of problems that may affect the smooth running of the projects as well as an opportunity to introduce new technical advice to boost production. Livestock projects take long period of time to establish, i.e. for the financial turn over to be realized. It takes long time for farmers in these projects to make investments from the proceeds of the livestock projects. For this reason, there is need for the number of beneficiaries for each pass-on livestock project to take into account the number of beasts at project establishment and also the number per each beneficiary group. However, the projects should still be encouraged as they will take full operation at a later stage and be of benefit to the rural disadvantaged who cannot access other means to own cattle, which in turn play a pivotal role in crop production (through draft power, manure provision) and cash earnings that indirectly ensures food security. Regardless of approach used, livestock projects should be strongly supported because the districts under study are prone to poor crop production and hence the cattle can be a source of income and food. Participatory irrigation projects performed better than the conventionally implemented, despite their small hectarages. This proved that farmer participation can greatly improve the efficiency of development work and eliminate many of the problems regarding proprietorship and enhance development activities at community level. Conventional irrigation projects were plagued by problems of mismanagement and theft as was reflected by poor performance and malfunction of the conventional Chingechuru and Chimwe-Chegato irrigation schemes. Fencing theft atChingechuru irrigation scheme had brought it to a stand still. However, the larger incomes associated with the conventionally implemented irrigation projects were the result of the larger areas under cropping for these projects. Production levels in participatory irrigation schemes were good. Adoption of most technical innovations in livestock projects was found to be associated with the conventional approach. Asset procurement was a function of the farmer’s accessibility to non-project income, like formal employment, and procurement of specific assets applied more to project type than the approach to project implementation. This study found that the approach used in implementation had a greater influence on the performance of irrigation projects than livestock projects.

Critiquing the viability of a trade biased approach to regional integration in Southern Africa

- Description: Africa’s international marginalization is preponderantly conceptualized through world systems approaches, particularly structural dependency. Consequently, the region’s socioeconomic quagmire, characterized by economic stagnation, abysmal poverty, inequality and foreign dependency, is often attributed to its colonial heritage. Particular reference is made to the small size of the African state and its structural specialization in primary production. Collective self reliance based on mutual interdependence (regional integration) thus suggests itself as a logical way to overcome the structural constraints imposed by the small size of the state, while at the same time representing a viable alternative to asymmetric trade with developed countries.

- Description: Africa’s international marginalization is preponderantly conceptualized through world systems approaches, particularly structural dependency. Consequently, the region’s socioeconomic quagmire, characterized by economic stagnation, abysmal poverty, inequality and foreign dependency, is often attributed to its colonial heritage. Particular reference is made to the small size of the African state and its structural specialization in primary production. Collective self reliance based on mutual interdependence (regional integration) thus suggests itself as a logical way to overcome the structural constraints imposed by the small size of the state, while at the same time representing a viable alternative to asymmetric trade with developed countries. It is within the context of this theoretical framework that this study critiques the predisposition of the regional body in Southern Africa, the Southern African Development Community (SADC), towards a trade biased approach to regional integration (market integration). This critique is based on theoretical and empirical findings showing that trade led strategies are primarily suited for developed countries with robust manufacturing industries and complimentary production structures.

- Description: The purpose of this thesis is to disseminate research work done towards a higher degree and report on the findings of the research that was conducted relative to South African Public Private Partnership (PPP) projects. The research investigated perceptions of PPP actors on the performance of operational PPP projects. The aim of the research was to fulfil the requirements for the award of the degree of philosophiae doctor in construction management; contribute to the PPP body of knowledge; contribute further understanding of the performance of PPP projects in South Africa; and develop a systemic model for a sustainable PPP system within the country and beyond. All the aforementioned have been achieved, despite the research limitations as indicated in Chapter 1. A case study approach was adopted to examine various performance aspects of operational South African PPP projects. The research was a multi-case study design. Each individual case study consisted of a ‘whole’ study, in which facts were gathered from the selected PPP projects and conclusions drawn on those facts. A web-based questionnaire was used to capture the experiences and perceptions of various actors involved directly, or indirectly in selected PPP projects. The sample stratum consisted of all operational PPP projects registered in accordance with Treasury Regulations as of December 2005 and other projects that reached financial closure before the Public Finance Management Act of 1999 became effective. PPPs involve highly complex procurement processes, are relatively new in South Africa and to date have attracted limited investigation to refine our understanding of the operational performance of PPP projects. This is notable, as significant financial and other resources are involved, and the perception exists that service delivery in most parts of the country is poor. Key empirical evidence from the research indicates that South Africa has developed a robust policy and regulatory framework for PPPs; has an inadequate level of PPP awareness and training; and lacks the project management capacity to facilitate deal flow. It is suggested that further research be conducted on a yearly basis, preferably every six months, so that trends can be established concerning various aspects of other operational PPPs. Further, it is recommended that the PPP Unit commission sector-specific studies that will conduct further research, to compare research across PPP and non-PPP contracts. The choice to conduct a multi-case study required extensive resources and time beyond the means available to the researcher. Further, the sensitive nature of PPP projects made it difficult to obtain required data at the first attempt. However, the researcher made several follow up calls and reminders before eventually obtaining the required data from the respondents. A systemic PPP model has been developed for PPP implementation and management. This model was tested for appropriateness by conducting a further survey on PPP participants attending an international conference on 'Financing of Infrastructure Development in Africa through Public Private Partnerships’ staged in August 2007, in the St. George Hotel, Johannesburg, South Africa. The findings from this research make an invaluable and original contribution to the PPP body of knowledge, provide insight for further research in this important field, refine the understanding of operational PPP projects, and provide direction for policy and decision makers in the public and private sectors, within South Africa and beyond.

- Description: The syntheses of octasubstituted and unsusbstitituted Gallium(III) chloride and indium(III) chloride phthalocyanines (GaPc and InPc), their photophysical, photochemical and nonlinear optical parameters are hereby presented. The photocatalytic oxidation of 1-hexene using the synthesized GaPc and InPc complexes as well as electrochemical characterization is also presented in this thesis. Fluorescence quantum yields do not vary much among the four Ga complexes, except for complex 21c; therefore it was concluded that the effect of substituents is not significant among them. Solvents however, had an effect on the results. Lower Φ[subscript F] values were obtained in low viscosity solvents like toluene, relative to highly viscous solvents, such as DMSO. The triplet quantum yields were found to be lower in DMSO than in DMF and toluene. The rate constants for fluorescence, intersystem crossing and internal conversion as well as fluorescence and triplet lifetimes are reported. Photodegradation and singlet oxygen quantum yields have also been reported. There was no clear correlation between the latter parameters. It was however established that the four gallium MPcs were stable, within the allowed stability range for phthalocyanines. High quantum yields of triplet state (Φ[subscript T] ranging from 0.70 to 0.91 in dimethysulfoxide, DMSO) and singlet oxygen generation (Φ[subscript greek capital letter delta], ranging from 0.61 to 0.79 in DMSO) were obtained. Short triplet lifetimes 50 to 60 μs were obtained in DMSO). Calculated non-linear parameters of these complexes are compared with those of the corresponding GaPc derivatives and tetrasubstituted GaPc and InPc complexes. The optical limiting threshold intensity (I[subscript lim]) values for the InPc and GaPc derivatives were calculated and compared with those of corresponding tetrasubstituted InPc and GaPc complexes. The octasubstituted were found to be better optical limiters. Photocatalytic oxidation of 1-hexene by GaPc (21a-c) and InPc (22a-c) derivatives is also presented. The photocatalytic oxidation products for 1-hexene were 1,2- epoxyhexane and 1-hexen-3-ol. The % conversion values of 1-hexene and % selectivity of 1,2-epoxyhexane were generally higher for InPc derivatives. Even though InPc derivatives showed better photocatalytic results than GaPc derivatives, the former were less stable relative to the latter. Both type I and type II mechanism were implicated in the photocatalysis mechanism.

- Description: A series of 3,3-ethylenedioxy-exo- and endo- bornyl esters have been prepared and subjected to α-benzylation using lithium diisopropylamide and benzyl bromide. In the exo-series of esters the diastereofacial selectivity of benzylation was found to improve (up to 34% d.e.) as the steric bulk of the O-alkyl group increased, whereas in the endo-series, a surprising decrease in stereoselectivity was observed as the steric bulk increased – an observation attributed to flexibility of the metal-coordinated endo-enolate system, compared to the relative rigidity of the exo analogues. The conformational options for each series was explored at the density functional theory level. Reductive cyclization of a range of specially prepared N-carbobenzyloxy-amino acid esters has been shown to afford the corresponding derivatives, contrary to previous reports that the cyclization is limited to the glycine derivative. The cyclization sequence has been explored in detail, and the yield has been shown to be critically dependent on the stereochemistry of the α-amino acid moiety. Moreover, it seems that reductive cyclization occurs more readily with the endo- rather than the exo-bornyl N-CBZ-amino acid esters. Molecular modelling of relevant transition states at the DFT levels indicates that L-amino acid-derived systems should cyclize preferably in the exo-series and D-amino acid-derived systems should cyclize preferably in the endo series. Studies of alkylation of an iminolactone system have reported an interesting anomaly - exo-methylation is observed while endo-alkylation predominates for larger alkyl groups. This has been studied in detail at the DFT level, and the anomaly is attributed to thermodynamic control in the methyl case, whereas kinetic control is the norm in this system. Preliminary computer modelling of the intramolecular rearrangement of a 3,3-xylylbornyl system at the HF/STO-3G level raised doubts concerning the structure assigned by Evans to one of the rearrangement products, prompting an X-ray crystallographic analysis and leading to the revision of its structure from a pinene to a camphene derivative. The previously elusive spiro[bornane-3,2’-indan]-2-exo-tosylate has been successfully isolated, and the kinetics of its ready decomposition to the two camphene products has been followed by 1H NMR spectroscopy. The endo-tosylate analogue, on the other hand, was found to be remarkably stable. Kinetic data obtained for rearrangement of this exo-bornyl tosylate have indicated the operation of tandem autocatalytic and pseudo-first-order transformations leading sequentially to the two isomeric camphene products. An extensive coset analysis of all possible rearrangement processes of the initially-formed cation formed from decomposition of the exo-tosylate has afforded a graph containing 336 classical cations (modelled at the AM1 and B3LYP levels) and 526 transition-state complexes (modelled at the AM1 level). This analysis afforded a viable 4-step classical mechanism connecting the first camphene product with the second. A more realistic study, involving non-classical carbocations, has afforded a graph of all possible (classical and non-classical) cations that could be formed by rearrangment of the initiallyformed cation. The resulting graph confirms that the only energetically feasible path corresponds to the classical mechanism, but simply involves two steps, including a novel, concerted Wagner-Meerwein – 6,2-hydride shift – Wagner-Meerwein rearrangement.

Despite the fact that each of the clients was initially assessed as being a suitable candidate for psychological treatment, none of the cases proceeded to the therapy phase of treatment. A number of obstacles, both personal and contextual, were encountered during treatment implementation, preventing or limiting a successful outcome of psychological treatment in each case. An examination of these cases highlights a few of the many obstacles frequently faced when delivering psychological treatment to the South African context. In so doing, this research provides an opportunity to consider the possible reasons for the limited documentation of treatment efficacy within the South African context, as well as to enhance our understanding of and sensitivity towards the cultural and contextual factors playing a role in psychological treatment.

- Description: The paper examines the value of the South African National Arts Festival (NAF) in the transition to democracy using theories of cultural capital. NAF history from 1974 to 2004 is used to argue that the Festival provided an important arena for the expression of political resistance in the 1980s and, to some degree, continues to do so today. It is concluded that an important part of the value of the arts is their ability to provide a forum for debating the goals and values of society and that individualistic utility theory is not always successful in measuring such social value.

- Description: As a result of significantly improving relationship between South Africa and China, Chinese tourists traveling to South Africa have become a more noticeable group of travelers. More and more Chinese tourists choose South Africa as a tourism destination; especially Cape Town in the Western Cape region for a variety purposes such as relaxation, business and/or shopping. This research investigates the perceptions and motivation of Chinese tourists coming to the Western Cape region of South Africa. The proposed strategy of promoting the Western Cape region as a travel destination can be made based on the perceptions and motivation of Chinese tourists to the Western Cape. The study focuses on clearly understanding the perception of Chinese tourists by studying tourist behaviour and consumer motivation. The process of decision making and factors impacting on decision making are addressed in the research. A survey questionnaire was administered to Chinese tourists visiting South Africa. The primary data received by questionnaire was analyzed to show what actually Chinese tourists consider Western Cape as a travel destination. The Statistical Package of Social Science (SPSS) was utilized for analysis of data collected by the questionnaire. These general groups of data are discussed in the research. There are personal information, the motivation for travelling, and perceptions of respondents in the Western Cape region in South Africa.

- 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: 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: The creation of wealth is an important issue in any society, and entrepreneurship is regarded as an important catalyst in the creation of new wealth. This presents a challenge to develop entrepreneurship successfully. An important site for the development of entrepreneurship is higher education. The challenge however, is that there is a lack of a general understanding on how to educate students for entrepreneurship. In addition, current thought and practice on entrepreneurship education is historically biased, implying that graduates are essentially prepared for the past instead of for the future. From the perspective of higher education, the problem is how to develop current students to be entrepreneurial in the future. What is needed is to project into the future and then to develop an understanding of what should be taught as well as how it should be taught today. A versatile research technique that can assist in achieving this objective is the Delphi technique, as it is used to conduct futures research or research into areas where knowledge is incomplete. The Delphi method is a type of group interview, using the collective opinion of knowledgeable experts. The technique makes use of several rounds of data collection and feedback to create a consensus of opinion. Making use of the Delphi technique, research is being designed that will formulate expert‑based strategic guidelines on entrepreneurial education within the South African higher education sector. The aim of this paper is to illustrate the research design considerations that arise in the use of the Delphi technique for this purpose and how they are addressed. The main characteristics of the Delphi are presented and arguments for the use of the Delphi within a constructivist paradigm are discussed. Practical issues related to the design of the Delphi, panel‑member selection, and the formulation of panel questions, are examined. In illustrating these design considerations, the paper demonstrates a pragmatic approach to research design as well as the importance of creating coherence between the research question, the research paradigm, the research method and its use, encouraging research practitioners to adopt a more systematic, deliberate and philosophically‑based approach to research design.

- Description: This study investigates the assessment criteria of Unit Standard 115789: Communication Studies and Language. In general unit standards are registered, standardised statements of expected education and training outcomes including assessment criteria and other regulatory information required by training providers and assessors to train and assess learners under the Skills Development Act of 1998. However, it was found that many training providers and assessors share the view that in the case of Unit Standard 115789, among others, the assessment criteria and their descriptors are generic, vague and non-context specific to the extent that trainers and assessors have difficulty in developing appropriate and reliable assessment tools and instruments that allow them to adhere to the basic principles of assessment, namely transparency, validity, reliability, consistency, practicability, fairness, flexibility and usability. The main concern of the study is that learners will be declared communicatively competent individuals in a variety of professional and industrial environments when in fact they are not. The study traces the origins and development processes of Unit Standard 115789 in order to gain a clearer understanding of the problems experienced by training providers and assessors in the implementation of the assessment criteria. It then proposes a set of guidelines that will assist training providers and assessors to make the assessment criteria more accessible and the assessment processes more reliable, valid and consistent. Finally, it makes a number of recommendations to ensure that the problems of implementation of Unit Standard 115789 currently experienced by training providers and assessors are alleviated.

Human agency and development: re-politicizing human development

- Description: This thesis presents a value-laden understanding of development that acknowledges that development is human centered. The study re-emphasizes that human development which has become a powerful element of current development discourse is not just a social, economic and technological challenge; it is also an institutional and political challenge. The study therefore analyzes the notion of human development with the intention of improving it by placing more emphasis on the aspect of politics and human agency (the ability to act and be an agent of one‘s life). Politics here is understood beyond its usual institutional focus or identification with government, politicians and parliaments to include a much wider and much more important and dynamic range of activities found in all human groups such as institutions and societies. The study then demonstrates that since development is a process, individuals need to work collectively towards a common good so as to realize their development potential. This means creating a confederation of development where governments, citizens and non-governmental organizations work in partnership guided by a culture of collectiveness (civic culture) in order to produce more empowered citizens. The major argument in this study is the concern for citizens to effectively participate in areas that affect and impact on their lives and consequently be in a position to hold accountable institutions that affect their decision making capabilities. Hence human agency in this study signifies and can be justified as an important aspect of the process of participation leading to empowerment. , Thesis (PhD) -- Faculty of Management and Commerce, 2008
