- Description: The periodicity of formation of growth increments in the otoliths of South African sparids was validated by the oxytetracycline labelling technique. Intramuscular injections of oxytetracycline at a dosage of 250mg/kg marked the otoliths of laboratory held juvenile sparids, while a dosage range of 50 - 100mg/kg oxytetracycline, injected intramuscularly, marked adult sparids in the field. Laboratory held, larval sparid otoliths were marked by immersion for 24hrs a solution of 100-150mg/l alizarin complexone. Both daily (microstructural) and annual (macrostructural) growth increments were identified in the otoliths. The micro incremental pattern of deposition in the sparid otoliths conformed to the general pattern of otolith structure. Sparid otoliths consisted of a central opaque nucleus composed of multiple primordia. surrounding this nucleus were daily increments which decreased in width as the distance from the nucleus increased. Both check rings and subdaily increments were visible throughout the otolith. Minor environmental changes did not affect micro incremental deposition. Narrow opaque and wide hyaline annual growth zones were identified in sectioned sparid otoliths. Scanning electron microscope analysis of the annual growth zones revealed that microincrements within the opaque zone were narrowly spaced with prominent discontinuous phases. This resulted in the greater optical density and higher protein content of the zone. The hyaline zone was composed of widely spaced daily increments with prominent incremental phases accounting for the translucent nature of this zone. Opaque zone formation in the otoliths of many South African sparids was found to occur primarily during periods of reproductive activity and was shown to be indicative of slow otolith growth. The hyaline zone was formed after the spawning season, representative of fast otolith growth. The results of this study have resolved much of the controversy surrounding the rate of growth and time of formation of the opaque and hyaline growth zones in South African sparid otoliths.

- Description: This study examines the extent to which teachers in Senior Primary Schools who have obtained a professional qualification in Environmental Education, implement Environmental Education in their schools. It also explores factors which influence the implementation of Environmental Education at the Senior Primary School. Teachers who had qualified from Tlhabane and Hebron Colleges of Education were interviewed as were the principals of their schools and some of the lecturers who had taught them Environmental Education. The implementation of Environmental Education was addressed by means of comparing the teacher's responses with Primary Environmental Education Teacher Competencies as suggested by Glasgow and Robinson (1986) and Lahiry et al (1988). The information was deduced from the teachers responses from semi-structured interviews and were qualitatively analysed.

- Description: Considerable attention has in recent times been given to the attitudes of secondary school pupils towards Geography among black schools in South Africa. Many reasons account for this. It is partly because of the poor results and falling numbers of pupils in the discipline. Concern has also been expressed on the relevance of the Geography syllabus to the black pupils. Evidence suggests that these problems are evident in Transkei. The need therefore exists to assess pupils' attitudes towards Geography in Transkei. Arising from this background, this study sets out to assess the attitudes of secondary school pupils in Transkei towards Geography. Two hundred and thirty four pupils from eight urban and rural secondary schools in the Butterworth District of the Republic of Transkei were used in the study. Attitudes were measured in terms of "interest in Geography", "desire to study the discipline", "commitment to Geography" and the perceived relevance of the discipline. Through the use of techniques such as percentages, chi-square and principal component analysis - among others - for the analysis of the data, the following information emerged from the study: (1) Geography is generally perceived as being worthy of study; (2) Differences in responses were noted to result from a complex of factors which were grouped into home environmental factors and school environmental ones. (3) The major factor influencing attitudes towards Geography was noted to be home environmental conditions.In general pupils from lower income families expressed more positive views about the worth of Geography than those from the upper income families. From the above findings, it has been proposed that teachers and educational planners need to be made aware of these findings as they are important for classroom practice. It has also been recommended that there is a need to improve certain school practices such as taking pupils on Geography excursions more often as factors such as this were shown to improve pupils' attitudes towards the discipline.

- Description: Many white primary schools in South Africa have acquired computers which are being used in various ways. In my experience few members of staff are confident enough to use the computers in the school for educational purposes. Those who have been using them, generally have been doing computer literacy. The teachers in our school expressed the view that they would like to be able to use the computer, but that they lack the necessary skills and therefore would welcome some form of training. In my opinion computers should form an integral part of a child's learning environment. It has, for some time formed a part of his social environment, either in the home or in the workplace. For computers to be used effectively in the classroom, it follows that the teachers need to be trained to use them. In an attempt to overcome this problem, I designed and presented an in-service course, which used selected computer assisted learning (CAL) programs with teachers. These teachers then used these programs with the pupils in their class and evaluated the pupils' reactions to the innovation. As a result of the observations and the feedback provided by the sample of teachers, it is suggested that this might be a possible approach to in-service training for other schools. With adaptation it should be possible to follow this approach in any school which has a computer and someone on the staff who is willing to take the initiative to implement such an innovation.

- Description: A case study carried out at Edgewood College of Education (Natal) attempted to demonstrate how in-house training could provide staff with the necessary computer literacy skills to integrate computer technology into lecturing and teaching programmes. The duration of the project was six months and during this time a group of thirty academic staff members were exposed to computer technology via practical experience, lectures and demonstrations. The results gleaned from the project show that most of the staff involved in the project developed sufficient computer skills to be of benefit in their professional and personal tasks. In addition the recognition of the value of word processing and desk top publishing led to the staff encouraging students to use these software packages in the preparation of coursework. Consequently the use of the computer resources increased noticeably in the six month period. One of the goals of the study was to show how staff, once computer literate, would make use of generic software to integrate computer technology into their lecturing programmes. This did not happen and the reasons for this failure are discussed.

- Description: Aspects of fuzzy vector spaces and fuzzy groups are investigated, including linear independence, basis, dimension, group order, finitely generated groups and cyclic groups. It was necessary to consider cardinality of fuzzy sets and related issues, which included a question of ways in which to define functions between fuzzy sets. Among the results proved, are the additivity property of dimension for fuzzy vector spaces, Lagrange's Theorem for fuzzy groups ( the existing version of this theorem does not take fuzziness into account at all), a compactness property of finitely generated fuzzy groups and an extension of an earlier result on the order-homomorphisms. An open question is posed with regard to the existence of a basis for an arbitrary fuzzy vector space.

- Description: The Damara-Katanga orogen in central-southern Africa represents an area of 1.73xl0⁶ sq. km. The region is considered one of the wealthiest metallogenic provinces in the world. Successful exploration for stratabound base-metal deposits has taken place at this particular area since the introduction of more organised methodology in the early 1920s. The genesis, location and distribution of the ore deposits are related to their tectonic settings. Geodynamic evolution of the orogen, which initially formed part of a complex Pan-African rift system, comprises the following stages rifting; downwarping, including spreading on the western portion; syn-orogeny and late-orogeny. Two major tectonic events in the history of the region have been identified: the Katangan (900-750 Ma) and the Damaran episodes (750-500 Ma). Timing of mineralisation of ore deposits has been related to the evolutionary stages of the orogen. Genetic models of the most productive deposits are briefly discussed in this dissertation. The sedimentological, geochemical, paleogeographic and structural features can be employed as geological guidelines for integrated exploration programmes. Discoveries of major deposits and prospects in the orogen are also summarised, focussing on the exploration methods employed. The cost-effective use of the exploration techniques includes the classical copper-lead-zinc soil sampling for residual soils such as those in the Copperbelt area. Airborne magnetics and electromagnetics and follow-up ground geophysics have proved successful in areas where the cover is transported in the search for shallow ore deposits such as the Matchless massive sulphides. Remote sensing, geochemical and geophysical techniques have been tried in covered areas of western Botswana. The lack of geological control makes this interpretation difficult. A detailed geological mapping and the use of geochemical and geophysical techniques has been used to delineate carbonate-hosted base-metal deposits at the Otavi Land. The more expensive traditional methods necessary for the delineation of orebodies, such as pitting, trenching and drilling, are also discussed. Using a sequential approach, a possible exploration strategy is suggested, outlining the cost-effective use of remote sensing, geochemical and geophysical techniques. Standardisation in basic geological information is required for future successful explorations in the Damara-Katanga orogen, as well as attractive mining policies. In the event of their implementation, exploration perspectives are promising, specifically in terms of ore potential.

- Description: The problems of waste disposal in the tanning industry are unique in that the effluents are highly saline, have a high organic loading and contain heavy metals. Methods are available for the safe treatment and disposal of the latter two components, but the saline component requires the expensive outlay of evaporation ponds. This study has identified a possible use for the saline effluents, turning a problematic waste product into a potentially valuable by-product. A range of tannery effluents were identified and tested for their suitability for the mass cultivation of Dunaliella salina (bardawil strain). The bardawil strain was preferred over a local isolate because of its higher production of β-carotene. Ponded tannery effluents and combined processes effluent proved unsuitable for realistic propagation of the alga. Anaerobic digestion of combined processes effluent did not improve its suitability significantly. Anaerobic digestion of hide-soak effluent may remove persistent antimicrobial agents which influence algal growth, but its contribution to enhancing algal growth is equivocal. Undigested hide-soak effluent lacking in persistent antimicrobial agents was found to be an ideal culture medium, as no additional nutrients needed to be added. Significantly higher biomass was obtained in this effluent compared to chemically defined media. Induction of β-carotene was achieved in nitrogen-deficient defined media after culture in tannery effluent. This suggests that a two-stage system using hide-soak effluent for cell propagation and nitrogen deficient media for β-carotene induction, could be possible for the mass cultivation of D. salina for β-carotene production.

- Description: Alteration of serum tryptophan leads to parallel alterations in brain tryptophan levels. Such changes in brain tryptophan levels has been shown to lead to mood disturbances. The primary enzyme responsible for altering serum tryptophan levels is the liver cytosolic enzyme, tryptophan pyrrolase. Activation of this enzyme is responsible for the enhanced catabolism of circulating tryptophan. The purpose of the present study was firstly to establish whether there is a link between sex steroids and tryptophan pyrrolase activity especially since sex steroids are also known to cause mood disturbances and secondly to determine the effects of sex steroids on brain indolamine metabolism. The results show that all three sex steroids induce the activity of tryptophan pyrrolase implying that they decrease serum tryptophan levels by the activation of tryptophan pyrrolase, thus making less tryptophan available for uptake by the brain. It was also shown that the sex steroids enhance the uptake of ¹⁴C-tryptophan by brain synatopsomes. In addition, the sex steroids influenced the pattern of metabolism of serotonin by organ cultures of rat pineal glands. It is possible that the sex steroids regulate the availability and uptake of indoleamines in the brain.

In addition, the sex steroids influenced the pattern of metabolism of serotonin by organ cultures of rat pineal glands. It is possible that the sex steroids regulate the availability and uptake of indoleamines in the brain.

- Description: The South African academic research network, UNINET-ZA, evolved within two years from a FidoNet mail gateway that distributed email via interactive Kermit links, to a dialup uucp network, to wide area TCP/IP, and finally to full Internet connectivity. While the majority of UNINET-ZA sites are now TCP/IP connected, elements of the original gatewaying techniques are still fulfilling useful functions - for example a TCP/IP <=> FidoNet gateway, and links into non-Unix, non-TCP/IP based systems.

The evaluation of an individualised language programme in two multicultural Standard 9 classes : a pilot study

- Description: Two multicultural, mixed-ability Standard Nine classes (17 year olds) were selected for this pilot study. As they were half way through the Senior Secondary phase they had completed most of their English Language syllabus. There was a wide range of achievement in English in addition to which, fifteen of the thirty-nine pupils were English second language speakers. The teacher had to decide how to cope adequately with these differences in the subject English in general and in particular, in the Language component. A Language programme was devised, based on the prescribed textbooks. The pupils could work through the programme at their own pace and order and could consult the researcher during or after class time. The programme only covered the prescribed Language Study component and only a quarter of the total English time during an eight-week period (one term) was given to its completion. A Pre-test was set, the Senior Certificate Language examination paper of 1986, and the results analysed. The two classes were combined into one group and then randomly placed in the experimental and control groups apart from eight boys whose timetable requirements restricted them to being in the same group. The experimental and control groups were not matched. Aspects of Action Research were included in the design; pupils kept individual records; diaries were written by three pupils from each group and an independent observation was made of each group. A Post-test was administered (the 1989 Human Sciences Research Council examination) and this was followed by a questionnaire. The hypothesis, stated in null form, was: Pupils taught by individualised methods will not achieve better results than those taught by traditional methods. This hypothesis proved to be true. The experimental group, who achieved a better result in the pre-test maintained their lead over the control group but did not increase it. Neither group fared well on the post-test but the experimental group achieved a result slightly higher than the provincial average. The affective results were more positive, most pupils enjoying their autonomy and experiencing a sense of achievement despite their results in the post-test. A few preferred whole and small-group teaching, showing that the teacher needs to present the subject in more than one style. This small-scale experiment dealt only with one aspect of English teaching, but there is potential for development particularly with regard to the use of individualised programmes both for remedial and enrichment purposes. The innovative teacher in the multicultural classroom could use individualised programmes profitably as part of his teaching repertoire.

Working with the contemptuous client in psychotherapy

- Description: The purpose of this case study is to explore the issue of contempt in the therapeutic relationship. The aims are twofold; namely, to illustrate to what extent the case studied throws light on existing theories on contempt in psychotherapy, and to enquire about which stance adopted by the therapist is most appropriate in the therapeutic interaction with a contemptuous client. It investigates the validity of using the case study method in examining both the content and the process of this particular course of psychotherapy. Literature on contempt in psychotherapy is reviewed, as well as the foundation-stone on which it rests, namely, the Kleinian approach to envy . The concepts of the superego and false self are also drawn upon in understanding this particular client's dynamics. The client's therapy is then presented and explored, in order to gain insight into how a psychotherapist's understanding of the contemptuous client can clarify the process of therapy. It highlights the limitations and potentialities that exist in working in this sphere of resistance, and raises questions relevant to therapists faced with these clients. The case study shows how theory in this area is helpful in understanding the contemptuous client, and that the ability of the therapist to endure and survive the contempt of the client is a crucial factor in working with the contemptuous individual.

- Description: Africa is currently experiencing a movement toward more democratic systems of government. The causes of such changes are numerous, but the literature on African democratization, like that on similar changes elsewhere in the world, places emphasis on the role of internal or domestic factors. The role of international pressures toward democratization is almost completely ignored. The case of Mozambique illustrates the dangers of such an omission. During the past decade Mozambique has undergone considerable political change. The single-party, Marxist-Leninist oriented state has been replaced by a multi-party system, devoid of explicit references to any guiding ideology. The government has also expanded its contacts with the West, particularly by means of its assuming membership of the International Monetary Fund and the World Bank. These changes in Mozambique's political orientation have been accompanied by economic reforms, designed to arrest the precipitous decline in the Mozambican economy. In this dissertation I argue that the causes of both the economic and political reforms lie in this decline and in the government's need to secure capital and debt relief internationally. In order to do this, the Mozambican government had to change the aspects of its political system which were seen as being unacceptable by the West, in particular the lack of multi-party competition and its overtly Marxist orientation and close ties to socialist countries. Because the reforms had their primary genesis in Mozambique's need for international acceptance and not in the growth of popularly based democratic organisations, the reforms are fragile and their meaningfulness questionable.

Recruitment of juvenile marine fishes into permanently open and seasonally open estuarine systems on the southern coast of South Africa

- Description: The recruitment of juvenile marine fishes into the Knysna and Swartvlei estuaries was monitored over 30 months using seine, scoop and cast nets. The relative abundance, seasonality and growth of the dominant species are presented, and includes the Cape stumpnose Rhabdosargus holubi, white steenbras Lithognathus lithognathus, blacktail Diplodus sargus, strepie Sarpa salpa, Cape moony Monodactylus falciformis, southern mullet Liza richardsonii, groovy mullet Liza dumerilii, striped mullet Liza tricuspidens, flathead mullet Mugil cephalus, freshwater mullet Myxus capensis and leervis Lichia amia. Information on a further 12 species is also provided. Recruitment of most fish species into the Swartvlei and Knysna estuaries reaches a peak during summer, which coincides with maximum food resource availability and corresponds to the time when systems along this section of the coast are often open to the sea. Artificial winter breaching of the Swartvlei mouth has occurred in the past, and has generally led to the premature closure of the system and loss of the ‘head’ of water needed for the summer opening. This type of mouth manipulation leads to reduced availability of estuarine nursery areas for marine fishes along the southern Cape coast. Comparisons between the recruitment of juvenile fishes into the Knysna and Swartvlei estuaries indicate that higher densities of most species were recorded in the former system. This is attributed mainly to the fact that the Knysna mouth is deep, permanently open, and has a strong marine influence when compared to the shallow, narrow and seasonally closed Swartvlei mouth. However, in a regional context both Knysna and Swartvlei are large, unpolluted systems, which serve as important nursery areas for many species of fish. On this basis alone, these contrasting estuarine systems should be allocated the highest possible conservation status. , Rhodes University Libraries (Digitisation)

Masego Sekelema was also a student at Forte. 'In March, the hostel dwellers attacked our school,' Masego said. 'Police came in. We thought they would stop the attack. But they shot teargas into the school. One of our students was seriously hurt.' So the principal of Forte called a meeting. At the meeting people agreed that Forte should close. Students' lives were in danger. Since then, Forte students have been attending school at three primary schools in Molapo.

- Description: In a prison cell in Johannesburg in 1953 after months of solitary confinement Ruth First, one of South Africa's finest investigative joumalists, attempted to commit suicide. In a sense, information for this thesis has been gathered around the question of why First felt her life had reached a point where she wished it extinguished. The answer involves who she was, what she believed in and her perception at that moment in time of the magnitude of the defeat of all she had worked for. But this question has broader implications - it has been asked because its answer throws light not only on the particular joumalist, but on the radical press and on the political movements which gave it both life and readers. This study is divided into six sections: Origins and influences looks, firstly, at early Jewish migrations and Ruth's life up to the end of her schooling in Johannesburg, then at her university years and the influence on her life of the Communist Party of South Africa. A vigorously provocative life traces debates which led to the formation of the South African Congress of Democrats and the Congress Alliance. It looks, also, at the political influence of the white Left and the radical social fratemity. Trumpeters of freedom locates the origins of the radical press tradition in South Africa, then looks at the development of the two publications to which Ruth devoted most of her time: The Guardian/New Age and Fighting Talk. Writing left focuses on First's writing in connection with three campaigns: the farm labour and the potato boycott, womens' passes and the bus boycotts. These chapters are not a history of these campaigns, but an analysis of the influence on them of First's joumalism. Word wars is about the Treason Trial of 1956. The contention here is that the trial, in which First was one of the 'chief co-conspirators ', not only put the Congress Alliance in the dock, but was about the definition of three words: communism, violence and treason. In many ways it was a trial of the language of the Left, the tools of First's trade. Shifting focus looks at the period after Sharpeville and the 1960 State of Emergency. It considers the shift in First's writing necessitated by greater political oppression, a banning order and her exploration of the writing of books. Chapter 12 considers the massive setback to the Congress Alliance of the Rivonia Trial and the tactical errors which led the Congress leadership to the conclusion that armed struggle would succeed at that point in time. The final chapter is about First's detention, and her perceived personal defeat which resulted in her attempted suicide. The Postscript looks at First's successful attempts to come to terms with both a political and personal defeat. The work effectively ends, however, with her departure from South Africa.
