  • 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: There is little doubt that there is a widespread concern that the transition from the supportive environment of the training institution where mistakes are expected, self criticism is encouraged and both tutorial guidance and peer group friendship are readily available into a situation where professional and personal responsibilities are profoundly altered, where the methods used, the progress of the pupils, their parents' expectations, the working relationship with colleagues are now permanent responsibilities. This transition can be traumatic for some and a considerable ordeal for many.--Chapter 1, p. 10.

  • Description: A new prostaglandin - prostaglandin X (later renamed prostacyclin or prostaglandin I₂ (PGI₂)), was discovered by Moncada, Gryglewski, Bunting and Vane in 1976. This unstable substance was shown to be produced by vascular tissue and to be a vasodilator and the most potent endogenous inhibitor of platelet aggregation known. Because of its properties, it appeared that a lack of it may be related to the development and or maintenance of hypertension, a disorder featuring vasoconstriction and an increased tendency to arterial thrombosis. The present studies aimed to investigate this possibility using a rat model. A bioassay for prostacyclin was first perfected. This consisted of a modification of the method used by Moncada, Higgs and Vane (1977): PGI₂ released by rat aortic strips, during incubation in tris buffer, was measured by assessing the ability of the incubate to inhibit adenosine diphosphate induced aggregation of human platelets, as compared to the inhibitory effect of standard prostacyclin sodium salt. The specificity of the assay for the detection of PGI₂ was tested. The abil ity of hypertensive rat aorta to release prostacycl in was investigated in two studies. The first compared aortas of Wistar rats of the New Zealand genetically hypertensive strain (GH) with those of matched normotensive Wistar controls. In the second study, hypertension was induced by wrappi ng the ri ght kidney with surgical silk and removing the contralateral kidney. Ten weeks later, aortic generation of prostacyclin by these animals was compared with that of matched sham controls which had received identical surgical manipulation but for the application of silk to the right kidney. Contrary to expectation, in both forms of hypertension, aortas of the rats with elevated pressure produced consistently more prostacyclin than those of matched controls. In order to discover more about the relationship between elevated pressure and elevated PGI₂ production, the effect of pressure reduction with hypotensive agents on the ability of GH rat aortas to produce prostacyclin, was investigated. After pressure had been controlled within normal range for one week (achieved by oral administration of furosemide, dihydralazine and reserpine for one month), aortic PGI₂ was reduced in comparison with matched GH controls. However, the reduction was not consistent and statistical significance was not reached. Because it was subsequently reported by other workers, that some of the hypotensive agents which had been employed may effect prostaglandin levels per se, no conclusions could be drawn from this study as to any possible direct relationships between pressure and aortic prostacyclin generating capacity. A further means of reducing elevated pressure (which had no inherent effect on prostaglandin levels) was thus sought. A mechanical method was eventually selected, application of a silver clip to the aortas of GH rats, just below the diaphragm, producing an immediate reduction in pressure distal to the constriction. Eighteen hours with later, PGI₂ production by these distal aortas those of matched sham GH controls and was was compared found to be consistently reduced. These results indicate that the ability to produce PGI₂ may be influenced by prior local pressure changes and that the increased capacity of hypertensive rat aortas to generate prostacyclin may be related to the increased mechanical transmural stress consequent on elevated pressure. Since haemostatic balance must be influenced not only by vascular PGI₂ generation but also by platelet sensitivity to PGI₂, the response of GH platelets to the anti-aggregatory effect of prostacyc1in was also investigated. As it had been shown by Sinzinger, Si1berbauer, Horsch and Gall (1981) that intra-arterial infusion of PGI₂ in humans decreased platelet sensitivity to the substance, the possibility existed that platelet sensitivity in hypertension might be reduced. This hypothesis was, however, invalidated as the sensitivity of GH platelets to the anti-aggregatory effect of PGI₂ was almost identical to that of normotensive controls. The shortcomings of the methodology and the possible importance of these findings in the hypertensive animal are discussed. The idea that elevated PGI₂ in hypertension may play a protective role both with respect to platelet aggregation and in attenuating further pressure rises is considered. It is finally suggested that it will be possible to draw more accurate conclusions as to the meaning of the increased PGI₂ generation in hypertension (both in relation to vascular tone and platelet function) only when details of production of, and sensitivity to, thromboxane A₂ are known. Thromboxane A₂ (TXA₂) is a vasoconstrictor and promotor of aggregation (Hamberg, Svensson and Samuelson, 1975) and it may be that, despite elevated vascular PGI₂ generation, the TXA₂/PGI₂ balance is still tipped in favour of vasoconstriction and platelet aggregation in hypertension.

  • 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.
