- Description: The possibility of an effect of zinc on the rate of tumour cell division, mediated through a regulation of cellular cAMP concentration, was investigated in the present study in rats. Dietary Zn deficiency (< 1·5 mg Zn/kg) but not Zn excess (500 mg Zn/kg) resulted in an increased cAMP concentration in transplanted hepatoma cells. Neither treatment had any effect on the cAMP concentration in regenerating liver or normal resting liver. Both the deficient and excess Zn diets resulted in a small reduction in tumour growth (not statistically significant). The results seem to indicate that the relation investigated in the present study does not apply in the cell line used.

- Description: Our current knowledge of the Solar System, with a particular emphasis on the systems of interplanetary objects, is reviewed, and the theory of meteors and the reflection of radio waves from meteoric ionization is then discussed. A description of the meteor radar is given and a method of calibrating the antenna beam is developed. The main project comprises two parts: (a) A general survey of the radar echorate for 20 major and minor meteor streams and the sporadic meteor background, conducted from Grahamstown over the period 1986 April to 1988 January, is described. Definite shower activity was observed for all of the major and some of the minor showers. (b) Based on a scheme proposed by previous workers (Morton & Jones), a method of recovering meteor radiant distributions from the distribution of echo directions is developed. We devise a technique of compensating for possible distortions of the resulting radiant maps, which may arise due to the arisotropic antenna beam. This involves a system of echo-weighting. Radiant maps which showed considerably less distortion than those of the above workers were obtained without the weighting procedure. It is concluded that, although the method in its present form introduces spurious features into the maps, the principle is sound and should eventually be refined to produce the desired compensation

- Description: Marketing channels have traditionally been examined as commercial conduits the sale objective of which was to facilitate the flow of goods from producer to consumer. This approach emphasized functional and structural aspects of the channel and was primarily concerned with the efficiency of the distribution system. During the last two decades, marketing channels have increasingly been viewed as social systems affected by the behavioural dimensions of power, conflict, roles and communication. The rapid growth of vertical marketing systems with greater authority and interdependence between channel members, have stimulated interest in this field. Nevertheless, research has been limited and characterized by methodological problems and conceptual differences about the definitions of behavioural variables and their relationships. Some attempts have been made to develop an integrated framework within which to conduct research into channel relationships, but the validity and relaibility of these models has not been tested. This research project examined the relationship between the sources of conflict and stages in the conflict process. The sources of conflict were subdivided into attitudinal and structural categories, the latter being concerned with goal differences, the desire for autonomy in the face of interdependence and competition for scarce resources. The conflict process model adopted by the author assumes the existence of stages of latency, feeling, perception, manifestation and aftermath in each conflict episode. The first four were treated as separate behavioural states for which different levels of conflict intensity were measured. In order to provide greater explanatory power to the results of the analysis, the perceptions of two respondent groups were identified, namely the leader group, consisting of channel members responsible for the overall strategic interests of the channel, and the affected group, consisting of channel members who had been adversly affected by the activities of their partners in the channel dyad. In addition, respondents were asked to identify separately, their perceptions of the macro and micro levels of conflict in the four conflict states. The marketing channel for prescription medicines was selected for the study. The focal dyad consisted of retail pharmacy managers and doctors with single respondent perceptual measures being obtained from the retail pharmacy managers. A mail survey of all the retail pharmacy managers in South Africa, South West Africa/Namibia, and the independent homelands conducted in July 1987 resulted in a 40% response rate (1031 returns). Tests indicated statistically significant differences between the perceptual measures representing the sources and stages of conflict, the macro and micro levels of the stages of conflict and between the leader and the non-leader groups and the affected and non-affected groups. A sequential hierarchy in the level of conflict measured in the behavioural states was indicated, with decreasing levels of conflict being identified in states of latency, perception, feeling and manifestations, respectively. An analysis of the results revealed that attitudinal sources of conflict were more important that structural sources in measures of perceptions, feelings and manifestations of conflict behaviour. In the latent conflict state, structural sources assumed greater importance than attitudinal sources. In most of the measures, the sources of conflict were more correlated with perceptions of conflict at the macro level than the micro level. The exception was manifest conflict for which micro conflict levels were more important. The major sources of conflict were differences in perceptions, differences in goals and the lack of autonomy. The leader group indicated a particular concern for attitudinal factors, particularly communication difficulties. The affected group, whilst identifying attitudinal factors as being the most important, was especially concerned with their lack of autonomy from the doctor, rather than the competition for scarce resources which could have been expected. An overall assessment of the level of conflict between retail pharmacy managers and doctors indicated that the channel dyad was relatively free from conflict. Relationships were characterized by a degree of satisfaction, some degree of harmony and little evidence of conflict behaviour.

- Description: In the modern technical age in which we live , knowledge of the past is often pushed into the background As a result of this history teaching often becomes an attempt to pump an assortment of arbitrary facts into the minds of scholars by means of 'chalk and talk' methods. Educationists all over the world see this tendency as the major reason for the declining popularity of history as a school subject . In other parts of the world, such as the United States of America and Britain, education departments and teachers have faced this challenge and it seems as if the status of history as a school subject has been retrieved . In the Republic of South Africa the new core syllabuses are geared towards moving away from the earlier restricted emphasis of facts, but there is very little guidance on how teachers are to implement this 'new' approach, which focus more on the "how" of history and on the teaching of historical skills In this thesis museum visits as one of the modes of outdoor education, is studied as a possible additional alternative method of teaching history in South African schools . A study is made of what museums are and of the possible educational values of museum visits. It soon becomes clear that the major beneficial aspect of museum visits could be the acquisition of historical skills such as comprehension, application , analysis , synthesis and evaluation In order to gain insight into the practical implementation of museum visits several groups were observed while visiting the museum, after which two pilot studies were undertaken in the Kaffrarian and South African Missionary Museums with Black standard ten pupils and senior student teachers . Attention is given to aspects of administrative , teacher and pupil preparation the implementation of the visit and the types of follow-up work which could be used. During and after the implementation of the two pilot studies certain characteristic problems were experienced these are : the compilation of worksheets and cultural differences . The most important of language difficulties : It also became clear that education officers at museums find it difficult to cope with the special educational needs of the different visiting groups . For this reason an approach is advocated where the teacher compiles his own worksheet suited to the needs of his specific pupils Guidelines are given as to how pre-planned worksheets could be adapted : how different question-types could be used to compile a worksheet in which skills ascend from the simple to the complex: and how worksheets could be compiled for mixed ability groups. It is hoped that this thesis will lead to renewed interest in the use of the museum in the teaching of history and will serve as guideline for teachers planning to take history "out of its coffin".

The development of a concept of psychological well-being

- Description: This thesis focuses on the development of an operational and theoretically eclectic concept of psychological well-being. A comprehensive research strategy was employed to examine various personality factors thought to be components of psychological health (i.e., the basis of the proposed concept). The general approach involved four major phases: (1) the clustering of various variables and identification of underlying key factors purported to be related to psychological health based on the writer's clinical experience and review of the mental health literature, (2) the formulation of an ~ priori concept of psychological well-being based on the operational definition of those factors, (3) the construction of an inventory designed to examine the proposed concept, and (4) the interpretation of the results and their implications for the development of the overall concept based on the examination of the factorial structure, validity and reliability of the inventory. The"a posteriori concept" evolved out of this process. The results of the present study indicate that the most valid and reliable factorial components of psychological well-being are self regard,interpersonal relationship, independence, problem-solving, assertiveness,reality testing, stress tolerance, self-actualization and happiness; social responsibility and flexibility emerged as questionable components of the a posteriori concept. The inventory which was designed to study the concept was successful in significantly differentiating various levels of psychological health. This way of conceptualizing and assessing psychological well-being has potential applicability for mental health practitioners and researchers.

- Description: This study investigated the level of self-esteem of black and white high-school students using the Rosenberg self-esteem scale. One hundred and eighty six subjects were used, 63 of them being white while 118 were black. A validation of the Rosenberg scale for the black sample was attempted using a correlation between the scale score and a rating of the subjects by teachers. The results of the study showed no significant difference between the self-esteem levels, while the validation study failed to confirm the validity of the test for black subjects in South Africa. However, the validation study v/as rejected as inconclusive and the results of the comparison accepted as confirmatory of previous research. An incidental positive finding revealed that white males have higher self-esteem than white females,. The theory and past research of self-esteem comparisons between racial groups is reviewed. The conclusion is reached in this study that the concept of self-esteem has outlasted its usefulness in the field of comparisons between racial groups and research of a qualitative nature .can provide further data for the understanding of differences between racial groups. , Thesis (MA) -- Faculty of Humanities, Psychology, 1988

However, the validation study v/as rejected as inconclusive and the results of the comparison accepted as confirmatory of previous research. An incidental positive finding revealed that white males have higher self-esteem than white females,. The theory and past research of self-esteem comparisons between racial groups is reviewed. The conclusion is reached in this study that the concept of self-esteem has outlasted its usefulness in the field of comparisons between racial groups and research of a qualitative nature .can provide further data for the understanding of differences between racial groups. , Thesis (MA) -- Faculty of Humanities, Psychology, 1988

- Description: A new declarative language is presented which captures the expressibility of both logic programming languages and functional languages. This is achieved by conditional graph rewriting, with full unification as the parameter passing mechanism. The syntax and semantics are described both formally and informally, and examples are offered to support the expressibility claim made above. The language design is of further interest due to its uniformity and the inclusion of a novel mechanism for type inference in the presence of derived type hierarchies

A contribution towards an understanding of the intensive tank culture of an ornamental Cichlid, Aulonocara Baenschi, from Chipoka, Lake Malawi

- Description: The intensive tank culture of ornamental mouthbrooding cichlids poses several problems which limit their aquaculture potential. This project addressed some of these problems for Aulonocara baenschi. The production of juveniles in 2501 aquaria was accelerated when: a) aquaria were equipped with refuges, b) females of less than 70mm in standard length were used as broodstock, c) mouthbrooding females were replaced with gravid females at seven day intervals, and d) embryos were removed from the mouths of females at replacement times for artificial incubation. Two sex ratios also accelerated juvenile production. The sex ratio (male:females) 1:30 yielded the highest spawning returns per tank, and therefore represented the most effective utilization of aquarium space (a critical consideration for the small-scale culturist). Contrastingly, the sex ratio 1:12 yielded the highest clutch sizes and a high percentage female spawning return, and therefore represented the most effective utilization of broodstock (an important consideration for culturists inhibited by financial constraints or having an abundance of culture vessels). The reproductive behaviour of A. baenschi was described. Emphasis was given to aspects of reproduction of relevance to culture, for example; spawning times and seasons, clutch size and its relationship with female size, age and size of sexes at first spawning, embryo development rate and size of first swimming juveniles. The slow growth rate of juveniles, combined with a late attainment of marketable size (± seven months) was a major limitation affecting the cuIture potential of A. baenschi. Two factors favouring the cuIture of this species was the high survival rate recorded for both adults and juveniles, and the comparatively high prices fetched by fish on domestic wholesale markets (R4,00 per fish). It is recommended that A. baenschi should not be cultured exclusively for the relatively small South African ornamental fish market. A more profitable strategy for domestic culturists should involve a major production effort with A. baenschi and other desirable species of Aulonocara (e.g . A. ethelwynnae; A. hansbaenschi; A. stuartgranti & A. maylandi) for foreign markets (in particular, the U.S.A.; Western Europe & Japan). Not only are these markets massive, but prevailing exchange rates of the Rand with these currencies favour such a strategy.

Sequence in the mathematics syllabus : an investigation of the Senior Secondary Mathematics Syllabus (July 1984) of the Cape Education Department attempting to reconcile the demands of the strictly mathematical order and the developmental needs of pupils, modified by the mathematical potential of the electronic calculator : some teaching strategies resulting from new influences in the syllabus

- Description: This study was motivated by the latest revision of the mathematics syllabuses of the Cape Education Department. The most important changes to content in the Senior Secondary Mathematics Syllabus (July 1984) are the introduction of calculus and linear programming, the substitution of a section on analytical geometry for vector algebra and the recall of the remainder and factor theorems. The way in which these changes were introduced left the task of integrating them into the teaching process in the hands of individual teachers. This is a task of extreme importance. If one's classroom practice is to simply plough one's way through the syllabus, one loses many opportunities to make the study of mathematics meaningful and worthwhile. Accepting the view of the spiral nature of the curriculum where one returns to concepts and procedures at increasing levels of sophistication, one needs to identify the position of topics in this spiral and to trace their conceptual foundations. Analytical geometry is in particular need of this treatment. Similarly there are many opportunities for preparing for the introduction of calculus. If the teaching of calculus is left until the last moments of the Standard 10 year without proper groundwork, the pupil will be left with little time to develop an understanding of the concepts involved. It is the advent of calculators which presents the greatest challenge to mathematics education. We ignore this challenge to the detriment of our teaching. Taken seriously calculators have the potential to exert a radical influence on the content of curricula and examinations. They bring into question the time we spend on teaching arithmetic algorithms and the priority given to algebraic manipulation. Numercial methods gain new prominence. Calculators can even breathe new life into the existing curriculum. Their computing power can be harnessed not only to carry out specific calculations but also to introduce new topics and for concept reinforcement. The purpose of this study has been to bring about a proper integration of the new sections into the existing syllabus and to give some instances of how the calculator can become an integral part of the teaching/learning process

- Description: Masculinity and femininity are taken for granted as being a natural part of everyday existence forming acceptable images of what it means to be a man and a woman. It is revealed that in conforming to the sexual stereotype of what it means to be masculine and feminine, men's repression of their emotional life forms a counterpart of their oppression of women, for the repression of men's emotional life as a process, manifests itself through the oppression of women. The socioeconomic relations, being exploitative in nature, having been obscured and mystified by masculine and feminine forms of false consciousness, justify the prevalent social circumstances by portraying them as natural and inevitable, thus serving to hide the fact that men and women comprise of both, masculine and feminine characteristics. Disclosing the quality of the experience of men's repression of their emotional life as a counterpart of their oppression of women, through qualitative description and reflection, it is evident that individuality and human social relationships are restricted by the constraints of masculine and feminine stereotypes. It is clearly highlighted, that women help to perpetuate the repression of male emotional life and in turn their own oppression through supporting the successful work, status and power oriented 'macho' male. Through the recognition of the pressures, and a re-evaluation of the masculine role, men will no longer see cause to oppress women and through that there will no longer be a need to repress their own emotional life. There is a need for self-reflection in those individuals and groups restricted by the constraints of masculinity and femininity for the realization of new possibilities of enlightened social action and individuality.

This toolkit has been used in the development of three small ecological expert systems. This project has involved adapting the results of research in the field of explanation-generation, to the requirements of the ecologist users. The subsystem contains two major components. The first lists the rules that fired during a consultation. The second component comprises routines responsible for quantifying the effects on the system conclusions of the answers given to questions. These latter routines can be used to perform sensitivity analyses on the answers given. The incorporation of such routines in small expert systems is quite unique
