- Description: "Now let us refrain, I said, from calling Homer or any other poet to account regarding those arts to which his poems incidentally refer: we will not ask them, in case any poet has been a doctor and not a mere imitator of medical parlance, to show what patients have been restored to health by a poet" (Plato 1979 19). (1) Soos alle lesers van literatuur weet Plato dat die digter weinig bewys kan lewer dat die werklikheid waaroor hy skryf ook deur hom verander is. Uiteindelik sit hy net met die" sweet influence" van sy welluidende gedig (ibid . 21). Tog word hy verbied, en nie net, soos Plato wou veronderstel, omdat hy die irrasionele, die emosionele, die "laere" in die mens stimuleer nie.

- Description: Preface: Concept analysis utilising Piaget and Gagne's theories is an expanding area of research in the 'exact' sciences such as physics and chemistry. It is, however, new to the concepts in geography which are 'non-exact'. The thesis, then, is an exploratory study; and concept analysis is considered a possible methodology for examining the students' understanding of non-exact geography concepts. The thesis is divided into two parts. The first contains an examination of the theory of concept analysis and a critical review of empirical studies, with a view to applying concept analysis to the discipline of geography. The second part involves what has been termed a case study, where concepts are selected for analysis, and students were tested for their understanding of the concepts.

A Piagetian programme of intervention: facilitation of conceptual change and cognitive growth

- Description: This research aims (within a strictly Piagetian framework) toward the development of a programme of intervention which will facilitate cognitive development, conceptual change and scientific literacy for those individuals who experience difficulty in coping with contemporary scientific and technological concepts. The research focuses specifically on the development of a diagnostic battery useful for realising a conceptual profile of the individual. This profile would indicate personal areas of functional interests that can be used creatively as a starting point for the facilitation of cognitive growth. The goal of such a programme is not the acceleration of cognitive growth, but rather the restoration of the individual to the mainstream of transactions in which the process of growth can flourish. The proposed facilitatory programme makes use of Piagetian tasks in a voluntary, individualist mode of instruction comparable to recently developed techniques of scientific education programmes. In brief, this research analyses three specific areas: 1) The development of a body of theory that can assist in the development of such a facilitatory programme, 2) The development of a diagnostic battery to provide insight into the individual's level of conceptual development, 3) The realization of certain guidelines for an instructional procedure whereby facilitation of growth can begin . The experiment takes the form of a pilot study of twenty four black and white subjects, exploring whether the battery of Piagetian tasks reveals a profile of conceptual development of the individual. Unique conceptual profiles were realized for all individuals, with evidence pointing towards the existence of a relationship between functional interests and the more advanced areas of the individual's conceptual development.

- Description: The study investigated the validity of the Rathus Assertiveness Schedule (RAS) with a sample (N=l68) of the white South African undergraduate students. In terms of criterion- related validity, results indicated that ratings of external judges, unaware of their subjects' self-evaluation, correlated significantly with the assertiveness scores of the male subjects only. Construct validation of the RAS with ten personality traits measured by the Howarth Personality Questionnaire yielded results consistent with Wolpe's hypothesis that assertiveness relates inversely to anxiety. In addition, evidence was found to support the contention that assertiveness correlates negatively with inferiority. A principal components analysis of the RAS revealed a potentially useful factor structure for both males and females. A number of factors including situation-specific assertive behavior as well as factors measuring aggressiveness were identified for both sexes.

A reappraisal of the governorship of Sir Benjamin D'Urban at the Cape of Good Hope, 1834-1838

- Description: Preface: Sir Benjamin D'Urban only spent four years as Governor of the Cape Colony, yet to many people he is one of the most easily identifiable of all British Governors. The principal reason for this, it seems, is the continuing emphasis placed upon his short-lived settlement of the Colony's troublesome eastern frontier in 1835. The main objectives of this thesis have been to examine some of the most notable analyses of that settlement together with an attempt to remove D'Urban's governorship from the narrow and controversial confines imposed by his frontier policy. I have tried to place his governorship in the wider context of his day, examining the various controls upon him, and his overall role as Governor together with some of his administration's less well known but ultimately equally important aspects. In effect, I have tried to view D'Urban in 'the round '. The thesis makes no pretence at being a complete survey. Several important and possibly contributory aspects to a fuller understanding of D'Urban's Cape interlude - notably his ten years in various executive positions in the West Indies and British Guiana, and his period as commander-in-chief of the British army in Canada - were beyond the reach of anything more than a cursory review. Presumably there are documents relative to this period of D'Urban's life in the Archives in Montreal, Georgetown and London. D'Urban's reputation in South Africa continues to rest upon the short-lived system he established in 1835 and the great promise for future relations between black and white that many authors then and since saw in it, or alternately failed to see in it. With this in mind, and the realisation that 145 years and a succession of Governors, High Commissioners and Prime Ministers have passed since 1835, the following extract from the front page of The Daily Dispatch of 10 May, 1980, is revealing. It was reported that the Ciskei government demanded "all the land between the Kei and Fish Rivers, the Indian Ocean and the Stormberg Mountains to form the territory of an independent Ciskei ." The fundamental questions of to whom the land belongs and of how to establish a just modus vivendi with the Xhosa, which plagued both D'Urban's short administration and the Colonial Office for much of the Nineteenth Century are still with us today. Any analysis of his four year period as Governor of the Cape must necessarily be tempered by this realisation.

- Description: The object of geophysical surveys in mineral exploration has traditionally been to detect subsurface geological features, which may reflect the presence of mineralization in depth and, if possible, to measure the dimensions of the causative body. Geophysical methods may also be used to locate extensions to known mineralization and for determining the size, depth and internal characteristics of an orebody. Marked improvements in geological concepts of ore genesis have led to a better appreciation, amongst geologists, of mineralized environments, and this has had an effect on the use of geophysics in recent years. Geophysical surveys are being increasingly used as an aid in environmental reconstructions and the results of regional surveys may be used to provide an indirect guide to ore. One of the main applications of geophysics lies in areas where the orebodies and associated structures are not exposed, as most geophysical measurements are more expensive than surface geological or geochemical surveys.

- Description: Introduction: Phosphorus is an especially scarce element in the aquatic environment, yet it is of vital importance to living organisms: the pyrophosphate bond is the basis of biochemical energy transfer, and phosphate groups make up the backbone of the nucleic acids (Wetzel, 1975). An understanding of phosphorus movements and transformations is thus essential to a study of the biological functioning of a lake. The present report describes a study of phosphorus dynamics inSwartvlei, a lake with an extremely low pelagic primary production rate, in the order of 0,15 gC.m⁻².d⁻¹ (Robarts, 1973; Howard-Williams and Allanson, 1978). The littoral phosphorus dynamics of Swartvlei have been discussed in some detail (Howard-Williams, 1977; Howard-Williams and Allanson, 1978), and what follows is an attempt to quantify the changes in phosphorus concentration occurring in the deeper parts of the lake, which comprise some 57% of the total area.

A checklist of the flowering plants is presented. The flora of the reserve displays an affinity to five phytochoria (Capensis, Karoo-Namib, Sudano-Zambezian, Afro-montane and Indian Ocean Coastal Belt 1, of which the Karoo-Namib and Indian Ocean Coastal Belt are the most extensive. The flora of the Valley Bushveld is regarded as adequately conserved, but a recommendation is made to consolidate the study area with adjacent farms. A small herbarium, containing specimens of all species listed in the checklist, has been established. The climate of the study area is classified according to the Koppen classification as Cfa. Simultaneous air temperature recording at four separate localities demonstrated that differences exist between local ities of marginally different altitude, aspect and slope. The phenology of 51 plant species, recorded at monthly intervals over a continuous period of 478 days, is presented. These species are classified according to their response to air temperature and rainfall for the initiation of new growth, flowering and fruiting. Species exhibited a spectrum of responses ranging from endogenous to exogenous control over phenological events. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: From preface: The original purpose of this thesis was to make a comparative study of all the English literature which had been prescribed from 1945 to 1980 for study by all high school pupils in the Republic of South Africa, Zimbabwe and the ex-High Commission Territories. This proved to be a formidable task. However, most of the material collected, including all the individual poems prescribed, was recorded in table form. This proved too bulky a system for comparative purposes and the field was narrowed to include only that English literature which had been prescribed for candidates writing Matriculation or Senior Certificate examinations on the higher grade as part of the English Language syllabus. From time to time, however, reference will be made in this thesis to prescriptions for the lower grades and for the lower standards.

- Description: From preface: The original purpose of this thesis was to make a comparative study of all the English literature which had been prescribed from 1945 to 1980 for study by all high school pupils in the Republic of South Africa, Zimbabwe and the ex-High Commission Territories. This proved to be a formidable task. However, most of the material collected, including all the individual poems prescribed, was recorded in table form. This proved too bulky a system for comparative purposes and the field was narrowed to include only that English literature which had been prescribed for candidates writing Matriculation or Senior Certificate examinations on the higher grade as part of the English Language syllabus. From time to time, however, reference will be made in this thesis to prescriptions for the lower grades and for the lower standards.

Aspects of the biology of Caffrogobius Caffer (Günter) (Pisces : Teleostei : Gobiidae) in the Eastern Cape

- Description: Several strategies used by the gobiid fish Caffrogobius caffer enabling it to colonise the harsh intertidal environment in the eastern Cape were studied. Q. caffer is opportunistic in its use of available food resources and feeds throughout the day with a slight tendency towards crepuscular peaks of feeding activity. The system of space utilisation used by C. caffer is so organised that all individuals of the population have access to patchily distributed food resources. Current velocities occurring over high tide limit the movements of Qo caffer and interpool movements occur only during the initial stages of a rising tide and in the final stages of an ebbing tide when the current velocities are below the tolerance limit of Q. caffer. The epifauna associated with the alga Ulva rigida, which forms an important constituent of the diet of the intermediate size classes of Q. caffer, was examined and it appears that this epifauna is an important source of food to Q. caffer. This report presents the results of the first detailed study of the biology of an intertidal fish in southern Africa.

- Description: From preface: This study of the British settlers of 1820 in South Africa uses one party of emigrants as a unit of historical research. In unfolding their story, it attempts to discover how far the standard assumptions about the 1820 settlement are borne out by the historical facts. No systematic set of hypotheses for investigation was established in advance; instead, the structure of the thesis has been determined by the course of the narrative, and the main issues have emerged spontaneously as it has progressed. Although the chronology has been maintained as far as possible, the narrative itself does not follow an entirely straightforward course. The emigrant party of eighty-four men and their families under the leadership of John Bailie which is the subject of the study was officially subdivided five weeks after landing at Algoa Bay, and the dispersal of its members to the established towns of the colony began even sooner. At the end of the three-year period laid down as a residential qualification by Government, less than a third remained to claim land on the party's location in Albany.

- Description: From Introduction: This thesis then is a detailed study of Lessing's novels in an attempt to show her development as a writer. Her short stories are handled briefly in connection with her novels. For, although the short stories are among her finest work, focus on the novels is sufficient to show her growth as a writer. Hers is the small individual struggle to overcome the limitations of both her content and her form. To overcome the limitations of her content means expanding her own consciousness and re-forming life itself. Only when she is free and the world is free can she overcome the limitations of her content. Then, of course, she need no longer and can no longer write. The task seems as impossible as that of the dung beetles, but she nevertheless continues. Like the sacred beetles with "the sun between their feet" she carries on rolling the muck of the world into symbols of the truth.

- Description: Stratiform and stratabound ore deposits commonly show a direct relationship with rifts. This association is studied by developing a geodynamic model of mantle processes and crustal responses. The geodynamics of the earth can be modelled by the process of mantle advection, which involves the episodic generation and segregation of low density mantle diapirs and their rise and subsequent interaction with the crust. The theory of mantle advection explains the genetic association between rifting, magmatism, basin development and subsequent orogeny and metamorphism. Global evolution has passed through a number of major stages of non-uniformitarian development in which each cycle was characterized by fairly uniform behaviour terminated by intense geodynamic upheaval. The relationship between geological evolution and mantle advection is examined by reviewing the major characteristics of each of the cycles, which correspond to the Archean, Early Proterozoic, Mid Proterozoic, Late Proterozoic-Palaeo2oic, and Mesozoic - Cainozoic eras. Although mentle advection has controlled crustal processes throughout time, the decrease in the thermal energy of the earth has caused >the major evolutionary changes in response to thickening and a greater rigidity of the sialic crust. Rifts are penetrative taphrogenic faults in the earths crust which act as major conduits for the transfer of magmas, from the mantle and lower crustal levels, to the upper crust and the surface. Rifts are also permeable zones for the migration of metalliferous brines, generated by magmatic differentiation. These metalliferous brines would either be exhaled at surface to form stratiform volcanogenic and volcanosedimentary ore deposits , or would interact with preferential host horizons to form stratabound ore deposits . The associat ion between rifting and stratiform and stratabound ore deposits is illustrated by examining :he tectonic setting, and st ratigraphic relationships of typical ore deposit types .

Geological factors affecting the grade and tonnage of sandstone uranium deposits

- Description: The largest known reserves of uranium are found in sandstone deposits, in the form of roll-front, peneconcordant and stacked types. Drilling on spacings of between 50 m and 5 m centres is the current method of attempting to delineate such ore bodies but because of the apparent random distribution of the mineralization there is a large degree of uncertainty in these predictions. Even on drilling grids of 3,5 m centres the uncertainty in predicting the distribution of stringer ore in roll front mineralization is still 100 per cent. (Sandefur & Grant 1980). Because of escalating costs it is becoming increasingly less economically feasible to delineate bodies of this nature in this manner and much more reliance will have to be placed on the geologist's interpretation of ore distribution when calculating ore reserves. The grade and tonnage of a sandstone uranium deposit can only be calculated with some degree of confidence if the processes forming the ore body are fully understood. The aim of this review is to examine the factors governing the formation and geometry of a sandstone body, the mobility and fixation of uranium and to establish criteria which will enable a more confident prediction to be made of the distribution of sand bodies and the distribution of the mineralization within them

- Description: The occurrence of a major metalliferous province in Zambia and Zaire is a reflection of geological processes operating in a specific environment during a particular period. The size of orebodies, their grade, mineralogy, beneficiation characteristics and therefore the amount of metal produced are all ultimately functions of the geology of the ores. This study is primarily concerned with the effect geology has on tonnage-grade relationships of ore in situ on the Zambian Copperbelt. Five major topics related to ore tonnage and grade are reviewed here: -behaviour of copper and cobalt in surficial environments. -geological setting and gross lithostratigraphic relationships of mineralization. -characteristics of known orebodies. -geological factors affecting mining and beneficiation of ore. -orebody limits and estimation of tonnage and grade. In addition, the historical background to the problems discussed here is briefly described, and some general aspects of the evaluation, mining and beneficiation of Copperbelt ores are considered in relation to metal production.

Geological factors that influence the evaluation and exploitation of Canadian copper-zinc massive sulphide-, and Japanese polymetallic (kuroko) deposits

- Description: Volcanogenic massive sulphide deposits are important sources of base metals throughout the world. The Canadian Cu-Zn-(Au, Ag) deposits of Archaean age occur in greenstone terrains within the Canadian Shield. These deposits are closely associated with volcanic vents developed along zones of rifting within mobile belts. The vents are manifested by coarse felsic pyroclastics and/or rhyolitic domes. The Japanese Pb-Zn-Cu-Ba(Ag) deposits, generally known as Kuroko deposits, are of Miocene age, and although also associated with volcanic vents, are developed above zones of subduction. Mineralization in volcanogenic deposits is a result of submarine exhalation of metalliferous hydrothermal solutions derived from fractionation of predominantly calc-alkaline magmas. The deposits are characterized by certain geological features that result from the interaction of specific physical and chemical conditions during deposition. Primary features include massive and stringer sulphide bodies, alteration zones, mineralogical and metal zoning, and certain depositional textures and structures. These features are commonly modified by subsequent metamorphism and deformation which impart secondary ore textures and affect metal distribution and shape. The disparity in age between Canadian and Japanese deposits allows the entire spectrum of geological features to be studied; from the completely unaltered to the high deformed and recrystallized. The characteristic geological features are the prime factors which control the metal distribution and concentration, and the size and shape of the deposits, thereby influencing the viability of the respective ore bodies. A knowledge of these factors and the physico-chemical parameters which control them are thus fundamental in the "understanding" of these deposits. They ultimately control the geological interpretations and predictions made during ore body delineation, ore reserve estimation, mining and ore beneficiation.
