  • Description: In a plural society, riven by deep conflict, as is South Africa, where however the Press retains a considerable measure of freedom to contribute to the political process it is the political role which is of the greatest significance rather than, for example, the reflection by the Press of social values or the internal organisation of the Press as a social system. Although it is, of course, hardly possible completely to ignore these other aspects in any institutional study.

  • Description: Preface: The arrival of the 1820 Settlers in South Africa and their impact on the political and social life of the Cape Colony has been well covered by historical research. This work is an attempt to illuminate yet another area in which their impact was felt. The failure of the settlement scheme under which these people were introduced into the colony has tended to detract from the importance which agriculture played in the early years of their residence in South Africa. The failure of the first crops may well have ended the attempts by many to establish themselves on the land but for others it was the beginning of a process of adaptation to the agricultural conditions of a new country. In this they were remarkably successful and within a decade the English farming community of the eastern frontier was prospering. The theme of this work traces the progress of these farmers through the initial period of crop failures, which condemned the settlement in the eyes of many, and through the ensuing years and later misfortune, the Sixth Frontier war of 1834-35. Both these setbacks were very significant in moulding the development of agriculture as practised by these farmers. In the past, historians have tended to over-estimate the reverse suffered by these farmers during this frontier war. The seemingly paradoxical questions raised by the rapid recovery of this community after the war have been left largely unanswered. Some attempt is made in the pages which follow to shed new light on this issue. In the first three chapters of this work the letters written by Thomas Philipps to his family in Britain form the chief source of information. Much of this correspondence has already found wider publication in a volume edited by Arthur Keppel-Jones, but there are significant omissions, particularly with regard to Philipps' commentary on agricultural matters. Unfortunately, this series of letters ends in 1830, and the chief sources for the latter period of this work are the various entries made) on agricultural matters, in the Graham's Town Journal, together with the farm diary of James Collett, another frontier farmer. From these, and various other works, it has been possible to trace the major developments of this farming community.

The development of a morphometric model for the estimation of mean annual sediment yield in ungauged catchments of South African river systems

  • Description: Hydrologists are regularly faced with the unenviable task of having to predict the magnitude and frequency of phenomena such as floods and droughts; and rates of erosion. If long records are available for analysis the hydrologist is able to base his predictions on the premise that the pattern of variation that has been observed in the past will persist in the future. The confidence that can be placed in any estimate consequently depends to a large extent on the length of time over which the phenomena have been measured at the problem site. Unfortunately the availability of adequate records tends to be the exception rather than the rule and in areas where there is inadequate data, it is necessary to resort to the hazardous procedure of transferring information from the gauged to the ungauged catchments. The transfer of information is accomplished by using empirical methods based on regionalised parameters, but the uncertainties involved together with the economic implications that could arise from a poor estimate, prompt the hydrologist to use as many methods as possible. The need for empirical methods of estimating mean annual sediment yield in ungauged catchments was first appreciated by the author when he was involved in the estimation of design floods and sediment accumulation at sites for proposed reservoirs. Empirical methods of estimating sediment yield are frequently used in an engineering context, but little attention has been given to the catchment surface from which the sediment supply is derived. It is perhaps in this often neglected field of research that the physical geographer can make a contribution. The principal aim of the thesis, more fully discussed in Chapter I, was the development of a morphometric model which could be used to estimate mean annual sediment yield in ungauged catchments in South Africa. The data used in the development of the model were drawn from the catchments, described in Appendix A, that cover a wide range of climate and topography. A description of the approaches adopted by other researchers for the development of empirical models of estimating sediment yield which forms the background to the model has been included as Appendix B. The model was first developed in an elementary form as the focus of a research project which was documented in the form of three reports of research in progress (Roberts, 1973 a, b and c). Analysis of the pattern of variation of suspended sediment yield provided a better understanding of factors affecting sediment yield and supported the selection of the prediction variable (Horton's P ratio) which was used in the model. The concepts of network topology were utilised to gain insight into the environmental factors controlling both the P ratio and sediment yield. Reasons for the high correlation between the P ratio and sediment yield are suggested but it is felt that further research should be focused on this aspect. In order not to break the continuity and development of the steps taken in the derivation of the model details of the calculations are collected in Appendices C, D and E. While many of the figures and tables presented in the thesis appeared in technical notes prepared entirely by the author for the Department of Water Affairs, the views expressed in the thesis do not in any way, either explicitly or by implication, represent any official view or policy of the Department of Water Affairs.

A key to the adults of 23 of these species is given. 3. The known distribution of 23 species and seasonal occurrence of 19 species are illustrated and briefly discussed. 4. The general biology of the genus Sisyphus is discussed and the major behavioural and biological differences between the two subgenera Sisyphus and Neosisyphus are given. 5. The laboratory and field investigation into variations in behaviour and biology in eight species occurring in the Mkuzi Game Reserve, with regards to interspecific competition, is presented. 6. The known possible natural enemies of Sisyphus are mentioned and the extent of competition from other genera, based on field and laboratory observations, is outlined. 7. Summary tables of all data with a final tabulated evaluation of the suitability of species for introduction into Australia is given. 8. Nine species have been highly recommended for Australia. Six more species could be considered but most of these still need further investigation. The remaining nine species were found to be unsuitable for transfer to Australia.

The Klinghardt phonolites, South West Africa: Tertiary volcanism in western southern Africa

- Marsh, J S, Lock, B E

  • Authors: Marsh, J S , Lock, B E
  • Date: 1975
  • Language: English
  • Type: text , article
  • Identifier: http://hdl.handle.net/10962/70164 , vital:29627
  • Description: Over 1OO phonolite bodies of mid-Tertiary age occur in the Klinghardt Mountains, 1OO km SE of Luderitz in Southern South West Africa the only published account of these rocks is that of Kaiser (1926) who gives a generalized map and describes briefly the mode of occurrence and petrography of the phonolites. The phonolite bodies are concentrated in an area roughly 8OO km2 and constitute an excellent example of an areal volcanic field (Rittmann, 1962), i.e. the activity occurred at a number of vents spread over a wide area and in most cases only a single eruptive episode took place at each vent.

  • Description: The biology and ecology of an indigenous, non-pest insect on an indigenous host plant were investigated. The study includes a taxonomic description of this new species, an account of its general biology, monitoring of the seasonal fluctuations in numbers of the psyllid and its hymenopterous parasitoids, and a study of various aspects of the host plant, including nitrogen levels, water stress, leaf hardness, and the effect of cutting, in relation to spatial and temporal differences in insect population numbers. Natural enemies, inter- and intra-specific competition had very little determining influence on the population numbers of the psyllid. Temperature and humidity had little direct effect, but may have influenced the population dynamics via its effects on the host plant. Seasonal patterns in psyllid numbers followed fluctuations in nitrogen levels; statistically valid correlations were obtained between leaf nitrogen and psyllid numbers on individual trees at various times. These findings were supported by the results of preliminary laboratory experiments employing different fertilizer treatments. No effect of water stress or leaf hardness was clearly discerned. Cutting of trees altered the characteristics of the subsequent regenerative growth so as to allow massive psyllid infestations to develop, thus showing the tremendous importance of the host plant in determining population levels in this insect. Preliminary investigations of the nature and mechanism of this effect were conducted, and its significance is discussed. The relevance of these findings to modern concepts of regulation in insect populations and to principles of pest management is discussed.

The recruitment and ogranisation [i.e. organisation] of African labour for the Kimberley diamond mines: 1871-1888

  • Description: Behind the fortunes in diamonds, the great open mines and the teeming town that was early Kimberley, were African labourers. Diggers seemed scarcely to care about them unless they were "in short supply", and many historians have been interested only in the guns they carried home with them. This study is concerned with these men: where they came from, why and how they came, and their treatment while they worked in Kimberley. The initial inspiration for the study came from the chapter on diamond production in Sheila van der Horst's Native Labour in South Africa, a remarkable contribution to the history of the Diamond Fields. The later studies by G.V. Doxey and more recently by John Smalberger which have expanded on aspects of Van der Horst's work, have led me to delve more deeply into other areas upon which they have not touched. One potentially fruitful line of study which was beyond the scope of this work was an investigation into the degree to which the Griqualand West labour question affected the attempts at South African federation in the 1870's. The main sources for the work have been the Griqualand West archives in the Cape Archives, for the period 1872-1880, and the various Kimberley newspapers. Labour returns were printed monthly in the Griqualand West Government Gazette for most years, till 1880. Cape Blue Books were useful sources for the period after 1880. De Beers Consolidated Mines Ltd. hold very little material relating to the pre-amalgamation period, though the extant minute books of the De Beers and Kimberley Central Diamond Mining Companies provided valuable information. A considerable number of contemporary published works were also consulted but, though most made some reference to African labour, few contained anything worthy of mention.

  • Language: English
  • Type: Thesis , Masters , MFA
  • Identifier: vital:2478 , http://hdl.handle.net/10962/d1010640
  • Description: This inquiry incorporates anthropological surveys on the life and character of the shaman, some writings of the American Plains Indians, and artist's, whose life and work reflects the power/life force so integral to the beliefs of these so called primitive cultures. Since the artist cannot be separated from his environment, the actions and reactions of society have also been explored. The method of inquiry has been to establish, first, the way of the shaman, and then the way of the artist. Although each artist, reflects only certain aspects of the enquiry, there is a strong affinity in the life and works of them all.
