- Description: Aimed at replicating the results of an American study into "Burnout" in Group Home houseparents, this research had the following aims: 1) To ascertain the validity and reliability of the instrument used in the original study and presented as a "useful measure of burnout”. 2) To establish whether this line of research, within a highly problematic research field, can at present offer any guidelines in the resolution of the current staffing crisis faced by South African children's homes. 3} To describe more closely the burnout syndrome. 4) To study possible etiological factors within a local context. Sixty three houseparents completed questionaires and three independent measures of burnout were obtained. The results were regarded as having failed to replicate those of the original study. The reason for this was found to be the low validity of the original instrument. The main conclusion drawn was that the line of research adopted in the original study can offer only very tentative guidelines towards the resolution of the staffing crisis faced until such time as valid and reliable instruments to measure burnout have been developed. Many of the suggested relationships between situational variables and ones of personal characteristics were confirmed for the local population of houseparents. , Thesis (MSocSci) -- Faculty of Humanities, Psychology, 1983

- Description: Al/Cr atomic ratios of coexisting spinellids and ortho- and clinopyroxenes show a pattern of sympathetic variation that persists through ultramafic rocks of layered mafic complexes of upper-crustal type, Alpine complexes, and the nodules found in kimberlites and alkaline basalts. Simple expressions are empirically derived to link (Al/Cr) orthopyroxene and (Al/Cr)spinel ratios in putatively equilibrated rocks. Equivalence of spinel compositions in shallow layered complexes and kimberlite nodules of deep-seated origin negates direct crystallochemical control of Al/Cr ratios of spinels by pressure.

- 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.

It’s inevitable that 19th century colonialism should finally come to its end here, because here it surely reached its ultimate expression, open in the legalised land- and mineral-grabbing, open in the constitutionalized, institutionalized racism that was concealed by the British under the sly notion of uplift, the French and Portuguese under the sly notion of selective assimilation. Our extraordinarily obdurate crossbreed of Dutch, German, British, French as the South African white population produced a bluntness that unveiled everyone’s refined white racism: • the flags of European civilization dropped, and there it was, unashamedly, the ugliest creation of man, and they baptized the thing in the Dutch Reformed Church, called it apartheid, coining, to outlast Nazi terminology, the ultimate term for every manifestation, over the ages, in many countries, of race prejudice. Every country on earth could see its semblances here: and most peoples. The sun that never set over one or other of the 19th century colonial empires of the world is going down finally in South Africa.

At present on the union side there are 14 trade unions - M A W U will make it 15. But most of these unions are racial unions and what are called craft unions - that is their members only do certain kinds of jobs e.g. boilermakers or electricians etc. On the employer side nearly all the 8400 factories in the industry are members of the employer association SEIFSA. It is SEIFSA - which is the largest and most powerful employer association in South Africa - that negotiates for employers on the Industrial Council.

The biology of the sand shark Rhinobatos Annulatus, in Algoa Bay with notes on other elasmobranchs

- Description: The biology of the lesser sand shark, Rhinobatos annulatus, was studied off sandy beaches in Algoa Bay over a period of two years. Tagging studies, due to low numbers tagged, did not reveal major movements. However, comparison of numbers of sand sharks caught off the beach and deep water during summer and winter months suggested that migration occurred during these seasons with the animals being inshore in summer. Annual rings on the vertebral centra were used to determine age. Both sexes can reach a maximum age of seven years. Conventional growth curves could not be fitted and empirical curves were used to illustrate growth. The reproductive cycle was investigated and indicated that both sexes matured after three years of age. The breeding season was during late summer when the shallow water was utilized as a nursery area. The sand shark is an aplacental viviparous species with a gestation period of 10 months. Breeding occurred every year and fecundity increased with total body length to a maximum litter size of 10 young. The most important prey items taken inshore were the mysid Gastrosaccus psammodytes, the prawn Macropetasma africanum, the crab Ovalipes punctatus and the sand mussels Donax spp. Differential predation by different length classes of sand shark resulted from a dynamic zonation of these different size classes in the surf zone. Smallest individuals fed closest inshore. Seasonal variation recorded in the hepatosomatic index was primarily due to the accumulation of hepatic lipids. This variation showed significant correlations with the breeding cycle in adult sand sharks. The contribution of liver lipids to the formation of egg yolk was estimated and found to be secondary to lipid reserves for maintenance. Liver colour varied depended on the amount of liver lipids. Ancillary observations were made of other elasmobranchs in the surf zone. , Thesis (DPhil) -- Faculty of Science, 1983
