- Description: From preface: This dissertation is concerned with the impact of the implementation of a particular kind of agricultural development project, viz. Betterment Planning, upon a rural Black village in the Keiskammahoek Magisterial District of the Ciskei, in South Africa. The project was implemented in the mid-1960s, and involved the re-organisation of the village environment into demarcated arable, grazing and residential areas, which necessitated the villagers moving from their old, scattered residential clusters to several new, concentrated residential areas. This dissertation seeks to trace the consequences of this development project, and particularly the socio-economic consequences of the residential relocation that it involved.

- Description: From Introduction: An investigation into aspects of musical education in Grahamstown cannot be isolated from the prevailing economic and social influences and must be seen within that setting. By the 1830's Grahamstown had developed from the frontier military post of 1812, to a settlement with an increasing population, aware of the importance of general education in raising standards and whose attention was concentrated in commerce, allied with agriculture, being a wool centre and a halting-place for traders conveying merchandise northwards, by ox-wagon and later also the chief centre of the ostrich industry. This development had gone on despite a succession of Frontier Wars, the last in 1878. A military presence was felt throughout the years of the nineteenth century and into the early years of the next, although from the late 1850's the chief military posts were in King William's Town and not in Grahamstown. The 1860's witnessed the important discovery of diamonds in South Africa, the first of which was identified by the famous Grahamstonian, Dr William G. Atherstone. This discovery, together with the discovery of gold to the north in the 1880's and the new railway line in that direction side-tracking Grahamstown, plus a slump in the ostrich industry, resulted in the economic decline of the town, but it then directed its energy and enterprise in another direction, education. The many small schools, which had sprung up during earlier decades, were superseded by newly established larger ones, initially for boys, but the 1870's in South Africa saw a revolution in the education of girls (similar to that of the 1850's in England), an occurrence which had an important bearing upon the founding of high schools for girls and Grahamstown was no exception in this respect. In South Africa, tertiary education for women was introduced soon after 1900 (as had occurred in England in the 1870's) and Grahamstown again kept apace. The years of the twentieth century brought about numerous advances in communication (motor cars, roads, aeroplanes, the radio and telephone), the invention of the gramophone, the appearance of "talkies" to replace silent films, the development of electricity as a source of power, great changes from peace to war, worldwide and financial stringency. In addition droughts plagued the farming community. All these influenced life in Grahamstown and education in general. The age of many scholastic institutions in Grahamstown became such, that they were receiving the sons and daughters and also grandsons and granddaughters of former pupils. This continuity played an important part in establishing traditions. Aspects of musical education during more than a century will be examined, firstly, in connection with each individual school and tertiary institution and secondly, by means of a survey. The newspapers, "Graham's Town Journal" and "Grocott's Penny Mail" - later "Grocott's Daily Mail", will be referred to as "IJournal" and "Grocott's", respectively.

- Description: From the abstract: In the layered sequence of the Bushveld Complex a number of distinct, but possibly genetically related groups of transgressive, postcumulus, ultramafic and mafic rock are recognised. The main part of this thesis investigates a suite of postcumulus rocks for which the name iron-rich ultramafic pegmatite is proposed. The majority of iron-rich ultramafic pegmatite bodies examined are from the upper critical zone of the layered sequence at Rustenburg Platinum Mines Amandelbult Section, in the northern sector of the western Bushveld Complex. Field relationships imply that the iron-rich ultramafic pegmatites should be considered as an integral feature of the layered sequence, even though they transgress the cumulates. Consequently, this thesis also includes a study of the cumulate sequence at Amandelbult. A second group of postcumulus, ultramafic rocks which is investigated comprises latiniferous ultramafic pipes; the Driekop pipe has been selected as a case study. This thesis is presented in four sections, namely, an introduction and verview, and studies on the Driekop pipe, the cumulate sequence at mandelbult and the iron-rich ultramafic pegmatite suite. A new classification scheme of discordant bodies of postcumulus, ultramafic rock in he Bushveld Complex is proposed (see also Viljoen & Scoon, in press). In he scheme presented here, two main varieties of postcumulus, ultramafic rock re recognised, namely, non-platiniferous magnesian dunites and iron-rich ltramafic pegmatites.

- Description: This work constitutes a fundamental study of the interaction between chelating reagents and oxide minerals . The adsorption mechanisms have been elucidated for most of the systems generated by the oxides of copper(II) or iron(III) and chelating reagents octyl hydroxamate, N-phenylbenzohydroxamate, salicylaldoxime, 5-nitrosalicylaldoxime or 8-hydroxyquinoline. The results of the preliminary work on one of the systems, viz. the oxide-hydroxamate system, indicated that the classical type adsorption process, in which the reagent forms a uniform layer of chelate over the oxide surface was not applicable. Rather, the adsorption occurred via the formation of a discrete metal-chelate precipitate at the oxide surface. In order to better understand the associated with copper (II) oxide, adsorption process the oxide was recrystallized to produce a coarser material with a more uniform surface. This allowed the oxide surface to be viewed under the scanning electron microscope and also enabled the relative concentration of "surface" and "bulk" chelate to be assessed. A detailed investigation of the effect of the system variables; pH, conditioning period, concentration, temperature, surface area and dispersing reagent on the rate of precipitation of the copper chelate species of general form, Cu(chel)2' was made. In addition the chemical nature of the adsorbed species and the structural form of the precipitates were determined with the aid of infra-red spectroscopy and the scanning electron microscope. On the basis of these results a model has been formulated for the adsorption processes. In this model the adsorption dissolution, is considered to occur in stages: 1. Oxide dissolution, 2. metal complex formation, 3. Metal chelate precipitation at the oxide surface and 4. “bulk” chelate formation by post-precipitation processes. The precipitation process was examined in more detail by the study of the adsorption of chelate on copper metal. The results of this study showed that it was possible to relate the structural type of precipitate formed, ie. fibrous or platelike, to the degree of supersaturation of the metal complex in solution. Furthermore, it was found that the precipitate structure determined whether it remained attached to the surface or detached. Contact angle measurements of air bubbles on copper metal conditioned with chelate were related to the adsorption results in an attempt to isolate the optimum conditions for flotation of oxide minerals.

- Description: The general biology of the South African Cliff Swallow Hirundo spilodera was studied over a two year period in the central Orange Free State. This species is highly colonial, nesting mostly on man-made structures such as concrete road bridges. Adult birds were usually faithful to their breeding colony and very few individuals changed colonies. The Cliff Swallow had a surprisingly large vocal repertoire for a swallow and contact calls of the young were individually recognizable. Three species-specific ectoparasites parasitized the Cliff Swallow but none seemed to have a noticeable negative effect on the swallows. Breeding started earlier in larger colonies than in smaller ones and conspecific brood parasitism was a common feature in some colonies. Individual pairs made up to four breeding attempts per season. The findings of this study are compared with the available information on other members of the Hirundinidae and the advantages and costs of Cliff Swallow coloniality are discussed.

- Description: The purpose of the present study was to investigate word meaning and its development in primary school children (6-12 years) . It was argued that the learning and development of the meanings of words such as pain cannot be primarily explained by means of ostensive definition. Furthermore, existing theories of word meaning which deal predominantly with substantive words fail to account for the learning of non-ostensive words. The pertinent psychological, linguistic and developmental psycholinguistic approaches to word meaning are reviewed briefly. The prototype approaches to word meaning are modified to apply to non-ostensive words . The focus is on conceptual meaning, that is, the way in which the senses of a word alter in different contexts. It is argued that the meaning of the word is its use in a diversity of linguistic contexts. The term "grammar" is applied in a unique way to encompass the meaning of the word (which stems in part from the words with which it co-occurs) as well as its selective use with other words in the language. Ninety-five metalinguistically-phrased tasks comprising short questions and picture-story sequences were analyzed in depth. The tasks were administered individually. A flexible interview afforded additional probing for each question. The analysis comprised percentage scores of responses at different age levels together with verbatim transcripts and qualitative descriptions: Uniformity, variation and developmental trends were found on different tasks for any particular word. Developmental trends were noted in children's understanding of particular words (for example, same), thereby extending the findings of previous researchers. There was evidence for a progression in children's ability to take into consideration that a word alters its sense according to the linguistic context in which it occurs (for example, same as it relates to chair versus dress versus pain). A comprehensive account of the words meaning could be established when a diversity of tasks was applied for each word. Children of different age levels employed different strategies in answering the questions posed. A model is proposed to describe the development of the meaning of non-ostensive words during the primary school years. It is suggested that psycholinguistic studies on word meaning be re-evaluated and that language and reading programmes incorporate the notion of "grammar". Application of this approach to the study of substantive word meaning in preschool children has important implications for theories of word meaning and for therapeutic intervention.

- Description: Although the areas I intend to investigate are rather diverse, what unites them is a concern for the ancient and fascinating question of the relationship between language and thought. Assumptions concerning the latter are surely latent as the basis for any inquiry into language. One of my general purposes is to give some overt orientation to this problem which is all too often simply glossed over. More particularly, I am also concerned with shaping a new approach to Bantu linguistic inquiry in terms of an emphasis on discourse analysis. In the context of the burgeoning of discourse analysis internationally, the field has been seriously neglected in Southern Africa. Studies of discourse are, we believe, vital to advancing our knowledge of inter-ethnic communication and understanding, an area that cannot be ignored in Southern Africa. In more general terms, I hope that this thesis represents a challenge to linguistic inquiry in ways that we have already outlined above. Most importantly, is that while it appears that most South African linguists are satisfied with adopting a rigid monotheoretical approach, I differ, advocating a multitheoretical perspective. This, I believe, allows a greater and more holistic view not only of the 'data' in question but also in terms of the general nature of inquiry, as well as the 'world' it attempts to describe. The body of this thesis is divided into two sections which reflect the two central concerns we have outlined above. Section A, divided into three chapters, is chiefly concerned with the conceptual basis of Xhosa narrative and its linguistic manifestation. In this section we shall find cause to query and to redefine traditional approaches to the linguistic categories manifest in Xhosa narrative. In section B, also divided into three chapters, we shall be concerned with the development of a theory of narrative production with specific reference to intsomi production. In this section we include an in depth criticism of previous approaches to this problem before developing and applying our own theory. There are two appendices attached to this thesis. The first presents certain tables and figures relevant to chapter 4. while the second includes the narrative texts from which we draw our examples. (Introduction, p. 21-22)
