Narrative, analysis and description are the stuff of written history and their blend must vary according to the nature of the topic tackled. In a comprehensive history of a most complex subject such as the flag controversy, a story which has never been fully told and in which numerous committees, commissions, conferences, deputations, pressure groups and different compromise proposals make their appearance, narrative and description are inevitably prominent.

Pollen analysis of organic sediments from vleis in upland areas of the Central and marginal Karoo has provided a vegetation history spanning the late Quaternary in the Winterberg, Sneeuberg, Nuweveldberg and Cederberg Mountains. Fossil pollen studies indicate moist conditions at the beginning of the Holocene, followed by a drier period. The second half of the Holocene (4 600 BP) is characterised by moister conditions, becoming drier towards the present and resulting in a decline in grasslands and an increase in Karoo-bushes. In the western Cape, the late Pleistocene (15 000 to 10 000 BP) was characterised by conditions moister than the present. This was followed by a drier period which ameliorated in the late Holocene. Although climatic fluctuations occurred, fynbos has been maintained in situ throughout the sedimentation period (14 600 BP), highlighting the dominant role of the substrate and secondary importance of climate. Climatic changes caused a shuffling of plant communities within the Fynbos Biome - this long uninterrupted history may be one reason for the high species diversity of fynbos. San hunter-gatherers, who occupied southern Africa prior to 4 000 BP, had a negligible impact on the vegetation. Khoi herders, who were first documented in the fossil record about 1 800 BP, had a slight impact on the vegetation, particularly by altering the fire regime. However, the arrival of European Trekboers some four hundred years ago had a significant effect on the environment. Although the general climatic trend in the Karoo is one of a drier phase, the decline in grasses and eastward movement of xeric Karroid elements has been accelerated due to mismanagement and sedentary farming techniques. An extensive contemporary pollen rain study has been undertaken to examine the representivity of these fossil pollen data. The investigation shows that contemporary pollen rain is a good reflection of the vegetation communities in the Karoo and Cederberg. Multiple discriminant analysis compares fossil pollen assemblages with contemporary pollen spectra and proved useful for determining whether modern analogues exist for the fossil pollen assemblages. TWISA confirmed the zones derived from discriminant analysis. Environmental changes have occurred in the Karoo during the late Quaternary, resulting in fluctuations and changes in vegetation patterns which have been accelerated in the recent past by human activity.

The mobility of policy ideas and mechanisms across time and space provides a challenge: How best to conceptualise the routes and modes of travelling whereby ideas and instruments are transported from one location to another? Conceptual tools originally designed in public policy circles - such as lesson-drawing, modelling, policy diffusion, policy transfer and convergence - have more recently been introduced into criminological enquiries regarding the convergence of criminal justice policies. This thesis applies the conceptual framework of policy transfer (referring to conscious efforts on the part of social agencies to export-import lessons from one locale to another) to the field of policing with a specific emphasis on South African police reform after 1990. The central focus of this enquiry is the interplay between novel, often externally derived , ideas and practices with a national police force at a time of immense political transition. Selective aspects of South African police reform are explored with specific emphasis on how, in what way, and to what extent, local reform efforts have been influenced by global notions and practices of good policing.Three institutional conduits for reformist policing ideas are considered. In the first instance, the contribution of policing scholars, a knowledge-based community of some importance, to debates on the pathways for police reform are discussed with an emphasis on the theoretical and normative assumptions that have guided their analyses of a policing ethos and system beyond Apartheid. Secondly, the role of an interim policy mechanism, the National Police Board (created in terms of a peace agreement signed in 1991) in setting an agenda for police reform is considered. Thirdly, the discussion profiles the international development community as a constituency of importance in recent police reform efforts. The latter exploration proceeds through a case study method. Three distinct examples of donor aid in support of institutional reform are described with particular reference to the paradigms invoked, the cultural entrepreneurs and policy networks involved, and the contextual factors that facilitated and/or constrained reformist efforts. A wide range of data collection methods were utilised during the course of the research. A literature review of contemporary debates on policy transfer, police and security sector reform in both mature and emerging democracies was undertaken. Furthermore, a wide range of primary documentary sources and various official policy documents were consulted. Face to face interviews with members of various policy constituencies also provided source material. Lastly, participant observation of policy structures and field notes compiled during evaluative research of a number of donor assisted projects provided contextual observations of importance to the analysis. This enquiry supports the conclusion that there is growing convergence in the language and practices associated with democratic police reform. Yet the dilemmas of policy transfer from North to South - particularly (although not exclusively) in the context of aid packages - are often underestimated. Local experiments suggest that whilst policy transfers can facilitate policy change, policies transferred all too easily become victims of domestic contingencies. Empirical enquiries into the context, processes and outcomes associated with reformist interventions are necessary to sharpen our understanding of how exactly policy travels and to what local effect. Recent reform activity aimed at the South African Police illustrates the extent to which policy communities situated at the local, national and transnational level do not exist in isolation but rather stand in a complex and interactive relationship to one another.

Greater emphasis will be given to the more classical contributions and only a brief outline of the mathematical development will be presented where it is deemed necessary for the ensuing development of the thesis. In Chapter 3, a modified approach for portfolio selection in thinly-traded environments is proposed. This proposal concentrates on improving estimation of the inputs for practical implementation of the usual Markowitz portfolio selection routine. The estimation procedure adopted makes corrections for thin-trading and also makes use of the CAPM to improve the vector of return inputs. Chapter 4, basically consists of four sections. The first, gives a brief outline on historical estimation problems associated with the market model. In the second section the extent of thin-trading is investigated on the JSE. Furthermore a suitable beta estimation procedure which corrects for the effects of thin-trading is investigated empirically. In the third section an extended market model is proposed. This model leads to a more detailed, yet tractable structure of the risk components of stocks on smaller markets. An empirical investigation is subsequently conducted to investigate the risk structure of JSE stocks. In the last section of Chapter 4, an example of an empirical study using risk-adjusted returns is presented. The example considers the choice between bullion and South African gold shares from the international diversification perspective. In Chapter 5, empirical tests of the CAPM are conducted. This chapter consists of 2 main sections, namely, univariate tests and multivariate tests of the CAPM. Both of the tests also consider possible extensions of the CAPM by encorporating additional factors in the tests. Chapter 6 represents the main focus of this thesis, here the power of the univariate and multivariate tests of the CAPM are investigated using a simulation approach. The power investigation is conducted on simulated data that charaterizes the NYSE, however the JSE parameters are also considered. In the final section of this chapter the power of these tests are compared using various structured residual variance-covariance matrices. Lastly, some final thoughts and directions for future research are offered.

Of the estimated 6 000 African independent churches in Africa, approximately 3 000 are to be found in Southern Africa. Most of these are in the Republic of South Africa, where the history of the independent church movement goes back nearly a hundred years. The greatest concentration of independent churches in South Africa is to be found in the urban complexes round the cities of Johannesburg and Pretoria in the Southern Transvaal. Soweto, the complex of townships to the south-west of Johannesburg which houses about one million people, has about 900 of these independent churches. This study deals with independent churches in Soweto, and their relationship to their urban environment.

This paper does not concern itself with the diversity that can be found in the cartoons of Derek Bauer and Jonathan Shapiro (Zapiro), but rather chooses to focus on the potential of cartooning as a critical art practice. Given that the "flipside" of criticism is censorship, the effects of censorship on cartooning together with cartooning's response to censorship will also be examined. Cartoons published in the alternative press after the 1985 declaration of a State of Emergency, but preceding the unbanning of political organisations in February 1990, which comment directly on press or political censorship, as well as those which raise issues pertinent to censorship, provide the basis for examining the converse notions of criticism and censorship. Having said this it should also be stated at the outset that whilst this paper focuses on particular cartoons produced in specific historical circumstances, it is also intended that this paper will have broader implications for the development of a contemporary critical art practice. This paper proceeds from the premise that criticism and censorship are oppositional and antagonistic concepts which seldom appear alone. Criticism, particularly when expressed publicly and directed at specific interest groups (eg. a ruling elite) frequently evokes censorship, whilst censorship and repression in turn breed criticism and resistance.
