- Description: My interest in "Connected Breathing" began with my own experience of this technique during a Gestalt workshop. It had a profound impact on me. I knew practically nothing about the theory, or lack of a theory, but my interest had been aroused. In my reading on the subject later, I was struck by the incongruence between my experience and what I read I was supposed to be experiencing. This led me "zu der Sache selbst." By using the phenomenological method, this study then is an attempt to come to an essential description of the experience of "Connected Breathing" and to make some evaluation of its usefulness as a psychotherapeutic technique. "Connected Breathing" is the main technique of the “Rebirthing”movement. It is, therefore, necessary to give some account of the development and theory, if any, of this movement. "Rebirthing" does not claim to be a psychotherapy. However, its technique of "Connected Breathing" does seem to have much in common with the techniques used by various established somatic psychotherapies. A brief overview of the development of some of these psychotherapies and their emphasis on breathing techniques is, therefore, also essential.

- Description: [Introduction] Much of the information available on the prices of vegetables marketed through the fresh produce markets is of limited use to producers. This information contains the actual prices for individual years. This can obviously be taken as a guide to future prices but it does not necessarily mean that those prices are a true reflection of the general pattern. In this study an attempt will be made, firstly, to establish whether a general pattern exists in the prices of selected vegetables on the East London municipal market. This will be attempted by studying the prices obtained over the 1964-1979 period. Information of this nature can be used as a basis for the planning of future crops. Secondly, to determine the months which obtain the "best" prices for the selected vegetables taking into account the quantities supplied to the market.

- Description: [From the Preface]: A Study in Local History: Grahamstown 1883-1904 aims to draw into a coherent picture the threads of political attitudes, approaches to racial issues and changes confronting the late Victorians in Grahamstown, particularly in the areas of sanitation, public health and shifting commercial frontiers. The relation of local development to national affairs has been investigated, although attempts to define exactly how the former influenced the latter, and vice versa, would involve one in the proverbial chicken-and-egg syndrome. Let it suffice to say that an understanding of events in the microcosm, or locality, lends clarity to the cross-current of affairs at the national level. It begins at the point where Grahamstown's commercial importance in the Eastern Cape declines after a flourish of hopes in the prospects of the Port Alfred harbour as a means of bringing trade back to Grahamstown. The study concludes when the foundation of Rhodes University College in 1904, provides a new centre of development for the city.

- Description: Two delta and two gamma alcoholics were assessed by case study according to the theoretical formulations of Transactional Analysis. Scripts and Games were elicited through the Thematic Apperception Test, Laddering Procedure, and Life History. Analyses demonstrated, firstly, that parallels were present between the parent-child relationship and present adult transactions; secondly, that needs, fears, and control mechanisms were traceable to early parental injunctions; thirdly, that among these subjects, delta alcoholics tend to play the alcoholic game "Lush", and gamma alcoholics tend to play the alcoholic game "Drunk and Proud". It was concluded that the script and existential position appear to play an important role in the maintenance of the drinking pattern. Alcoholic Loss of Control appears to be influenced by the degree to which aggression is suppressed.

- Description: Preface: "The need for development as observed today is a problem peculiar to the 20th century. The current situation is characterised by the fact that there are no more empty places on the earth, while our use of dwindling resources is curbed by environmental constraint." (Mouly and Costa, 1974, 155). The need for development is not equally felt by all nations as disparities in income and standards of living on a national basis have dissected the world into developed and underdeveloped countries. Disparities also exist within nations. These divisions are not simply determined nor are the terms related to development clearly defined - a matter that will be discussed in Chapter Two. Impetus to developing underdeveloped countries may be provided by various means, such as a general injection of capital or by more specific development projects. The purpose of these projects is to initiate changes that are intended to promote rapid development of an area. An interest has been shown by Geographers in the ability of these projects to stimulate economic growth in surrounding areas (Silberfein, 1976). The resulting success of development projects is closely related, if not determined, in large measure, by the aims. In view of the need for the aims of development projects to be successfully fulfilled, research into what constitute constructive developmental aims would be beneficial. Previous studies have revealed problems encountered with conflicting aims and objectives (Mountjoy, 1971); poorly defined aims (de Wilde, 1967); and inadequate groundwork prior to initiating the project (Berry, 1976). It is the intention of the study to examine the impact made by a development project in an underdeveloped area, and thereby assess the extent to which the development aims have been carried out. In order to carry out an examination of a development project in an underdeveloped area, an area in need of development had to be selected; a project within the area chosen for study; and the particular aim of the project examined. The Ciskei, a Homeland in South Africa, was chosen as a suitable area for study. A number of factors contribute towards it being an area in need of development, particularly as the Ciskei is a small country and dependent on South Africa, which is explained in the overview of the Ciskei in Chapter One. Three characteristics of underdevelopment noted by Seers (1972) are poverty, inequality and underemployment. Of these three factors it was decided to focus on unemployment as the indication of the extent to which development has taken place. The reduction of unemployment was one of the aims of the Keiskammahoek Irrigation Scheme, the project chosen for study. The overview concludes with a presentation of the Keiskamma Irrigation Scheme.

- Description: An intensive study was conducted on the free-living larvae and parasitic life stages of R.glabroscutatum on Angora and Boer goats in the Uitenhage district. Free-living larvae exhibited periods of maximum relative abundance during months of generally lower rainfall, from the end of autumn to the beginning of spring. Relative larval abundance in open and gully sites was low while larvae were rarely found in bush sites. Relative abundance was higher at 20h00 than at 08h00 and 14h00. Repeated sampling in the same areas did not reduce larval numbers. Over 99% of parasitic ticks removed from Angora and Boer goats were located on the feet. The annual occurrence of a low and variable number of parasitic immatures was synchronous with the occurrence of free-living larvae. High, less variable numbers of adult ticks were removed from goat feet from September to December, the highest numbers being recorded during October and November. The occurrence of a single period of parasitic adult abundance annually indicated a life cycle with 1 generation per anum. There were higher numbers of adult ticks on the feet of the Angora goats than on the Boer goats. Adult numbers were higher on the hind feet of both breeds of goats than on the front feet. R.glabroscutatum adults seem to be implicated in the aetiology of foot abscesses since more infections were observed in Angora goats than in Boer goats and on the hind feet rather than the front feet within both goat groups. In addition R.glabroscutatum adults attached at interdigital sites where abscesses also originated and reached highest numbers in October and November when abscesses were most frequently observed. A review of distribution and host records indicated that R.glabroscutatum was limited in its distribution to the eastern Cape Province, being primarily located in South Africa's major mohair producing areas. R.glabroscutatum was classed an obligative xerophile on the basis of its recorded occurrence in non coastal areas with a low annual rainfall and Karoo and Karroid Bush vegetation. Host records for R.glabroscutatum included 10 species of wild ungulate, sheep, goats and cattle. The common site of occurrence on small stock and on small to medium sized wild animals appeared to be the legs and feet.

- Description: In 1982, it was reported that one in every three students who fail at South African universities, do not pass because of experiences of excessive anxiety resulting from university examinations. A survey conducted amongst student counsellors and counselling services on all South African university campuses, revealed a deficiency of group and individual therapy for this phenomenon of examination anxiety. The cause of this deficiency, was found to be the already excessive demands made on the time of student counsellors. Noting a similar situation at Rhodes University, the present investigation was initiated, with the aim of developing an economical group counselling programme for test anxious students on Rhodes campus. Sixty-four Rhodes students (who identified themselves as test anxious) volunteered for this investigation. These Subjects were randomly assigned to one of four treatment programmes (each divided into two groups, where Group A, N=6 and Group B, N=7) and a wait-list control group (N=12). Three of the treatments featured multicomponent programmes, each offering a cluster of behavioural interventions centred around: Study Skills Training/Counselling; Systematic Desensitisation (Using individually-constructed anxiety hierarchies); Systematic Desensitisation (Using group-constructed anxiety hierarchies). Included in addition, was a single-component treatment, featuring cognitive modification: a component much favoured by local test anxiety counsellors. Given adverse reports concerning the efficacy of single component programmes, when contrasted with multi component treatments, the cognitive modification package was included as a placebo. A battery of measures was used to assess test anxiety and progress made by Subjects to assuage its debilitative effects . The measures included: (a) Six Self-report measures (including a treatment evaluation schedule and the maintenance of a diary of experience by each Subject); (b) Two measures of physiological reactivity, viz. pulse rate and finger sweat print; and (c) One 'observable' measure, that of academic performance. Using these measures, an assessment of the performance gains or losses by each of the Subjects, was made on three occasions: at pre-treatment, post-treatment and 6-month follow-up. In support of the a priori hypotheses, the systematic desensitisation and study skills multicomponent programmes, realised significant gains on all measures over both the placebo and control groups (with exception of the higher score achieved by placebo subjects over that of the study skills group, on the treatment evaluation schedule) . This finding confirmed the superiority of multicomponent programmes over those with only a single component. The systematic desensitisation programmes proved to be the most effective, as measured on self-report and physiological measures. The superiority of group-constructed anxiety hierarchies over those individually-constructed was established. Study skills training helped Subjects to realise and maintain gains on the academic performance measure, although it took many of these subjects six months, before they had fully incorporated the study techniques taught, in with their own study habits. In discussion of the findings, the evident need to match test anxious students to programmes which "best suit" their characteristics, is presented, and solutions proposed. Weaknesses evident in the measuring instruments and research design, are also highlighted for discussion. As part of this experimental investigation, a discussion on the nature of test anxiety and its links with anxiety theory is introduced, together with a review of problems in measuring test anxiety; popular behavioural treatments used to relieve test anxiety; and a survey of test anxiety counselling on South African campuses. Advice for the therapist/counsellor, the academic, and the researcher, are posited in conclusion.

- Description: This research project investigates black cognitive structuring of their residential environment in the Grahamstown location. A clinical psychological method (repertory grid method) was used to elicit the construct systems of residents. The associative construct theory formulated by Kelly (1955) was used in interpreting the data set from the liberal perspective. The radical perspective demonstrated an alternative interpretation. A focus of the study centres around the possible implications of this type of research for planning action. The results showed that the repertory grid did appear to accurately reflect people's construing systems regarding their circumstances and behaviour. However, Kelly's (1955) Personal Construct Theory proved inadequate as a theory of explanation as to why people construed in the manner they did. To enhance this explanation, the marxist approach to the theory of knowledge was investigated.

- Description: From Chapter 1: It has been a long standing belief that many nickel sulphide ores are derivatives of magmatic processes in ultramafic and mafic rocks, and that they segregate from these magmas as immiscible sulphide droplets which are then concentrated into an orebody by gravitational settling either during intrusion or extrusion, or during the early stages of crystallization of the magma (Naldrett, 1981). Some geologists however, have suggested alternative mechanisms to explain the concentration of nickeliferous sulphides in the mafic and ultramafic hosts. These include hydrothermal replacement (Fleet, 1977), exhalative volcanic processes (Lusk, 1976), or major metamorphic upgrading of low grade, initially magmatic deposits (Barrett et al., 1977). It is not the purpose of this study to verify or disprove these hypotheses, but in so far as the initial concentration of sulphides in most deposits is concerned, these effects are relatively unimportant (Naldrett, 1981). The nickel sulphide ores associated with these mafic and ultramafic host rocks, invariably consist of nickeliferous pyrrhotite as the dominant phase, together with lesser, but variable, amounts of magnetite, pentlandite, chalcopyrite, cubanite, and platinum group elements (Reynolds, 1982).

- Description: From Introduction: There are few more emotive and contentious contemporary issues of enduring nature than the subject of economic sanctions and South Africa. The controversy surrounding this issue has implications for the structure of international social, political and economic order. The threads of the debate are woven into the historical fabric of the past two decades, during which the acrimony of arguments both for and against sanctions on South Africa has increased. Indeed, for each argument in the debate can be found a counter-argument and "lies, damned lies and statistics" abound. The complex and widespread nature of the question has elevated a practical issue into the realm of theoretical analysis. This thesis is neither purely descriptive nor purely theoretical. It has essentially two focal points, firstly, an attempt at a systematic and reasoned investigation of the many claims and counter-claims, designed to put these arguments into a broad economic framework. There is generally a greater volume of pro-sanctions literature than anti-sanctions literature, some of which is freely available in South Africa, while some is restricted and some not available at all. However, this partial lack of accessibility would seem to pose no material problem of omission: as much of the literature is repetitive, the unavailable material is usually adequately "represented" by material which is available. Also a great part of the literature contains little or no economic analysis since it focuses more on political issues. In this respect the thesis tries to represent the main points of the broad arguments concerned rather than individual nuances and personal viewpoints. It is concerned with sanctions of an economic nature rather than wider sanctions that may affect South African citizens more generally, for example, sport and diplomatic boycotts, bans and restrictions on international travel, etc.

- Description: Anomalous element distributions within the regolith result from chemical adjustments of the earth's surface to prevailing climatic conditions. Because of the lack of moisture in the arid environment, chemical equilibrium related to paleoclimates is largely maintained. Mechanical or clastic dispersion dominates arid weathering and hence the exploration approach is largely dictated by the degree of preservation of the paleoregolith. Arid environment geochemists thus have to contend with surface materials ranging from laterite and calcrete in areas where the imprint of aridity is minimal, to more conventional sample media such as bedrock, stream sediment and lithic soils in actively dissecting areas. Extraction techniques are designed specifically to isolate clastic dispersion trains. Thick mantles of aeolian and water-borne overburden characterise desert lowlands and are a challenge to the exploration geochemist. Techniques showing the most promise in these areas include groundwater geochemistry, vapour geochemistry, surface microlayer geochemistry, geobotany and biogeochemistry which attempt to isolate gaseous and weak hydromorphic, ore-related trace-element dispersions. Termite mound sampling yields convincing results and appears to be an under-utilised geochemical approach. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: The Central and Southern Domains of the Koras Group, situated on the Doornberg Lineament, are the structurally preserved remnants of a once more widespread late-syntectonic cover sequence. Detailed examination of the field relationships, lithology and petrography together with new geochemical data (30 analyses) has resulted in the proposal of a new geological succession consisting mainly of two cycles of bimodal basaltic-rhyolitic volcanics with interbedded, immature conglomerates and lithic greywackes. These two cycles, named the Boomrivier and Leeudraai Formations, are overlain by the immature, polymictic orthoconglomerates and red arkosic sandstones of the Kalkpunt Formation. The first volcanic cycle commenced with the Lambrechtsdrif basaltic andesites and was followed, after a short hiatus, by the Swartkopsleegte rhyodacites. The second cycle comprises the Rouxville basalts and basaltic andesites and the Swartkop and Kenilworth rhyolites. Field evidence suggests that eruption of the rhyolitic and basaltic volcanics in the second cycle was contemporaneous. Geochemically, the volcanics can be classified as an "average-K" to high-K, tholeiitic, subalkaline association which exhibits general similarities to other Southern African bimodal associations e.g., the tholeiitic lavas of the Wilgenhoutsdrif Group. The Koras Group is petrologically similar to the Sinclair Sequence which is presently considered to be its coeval equivalent, but the dominantly calc-alkaline character of the Sinclair rocks distinguishes them from the dominantly tholeiitic Koras lavas. In a short literature review, the four main hypotheses for the petrogenesis of bimodal associations: liquid immiscibility, crystal fractionation, two-stage partial melting and separate magma sources, are described and the most feasible explanation for the origin of the Koras lavas is thought to be a "separate magma source" hypothesis in which two cycles of mantle-derived basalts and crustal-derived rhyolites were produced in a zone of high heat flow and erupted in an area of crustal weakness. The middle- or late-Proterozoic Koras Group was formed during unstable tectonic conditions, in a depositional setting that was probably controlled by late folding of the underlying pre-Koras sequences as well as the major strike-slip movement and subordinate dip-slip faulting in the Doornberg Lineament.
