  • Description: Rhodeo is the Independent Student Newspaper of Rhodes University. Located in Grahamstown, Rhodeo was established in 1947, and renamed in 1994 as Activate. During apartheid Rhodeo became an active part of the struggle for freedom of expression as part of the now defunct South African Student Press Union. Currently Activate is committed to informing Rhodes University students, staff and community members about relevant issues, mainly on campus. These issues range from hard news to more creative journalism. While Activate acts as a news source, one of its main objectives it to be accessible as a training ground for student journalists. The newspaper is run entirely by the students and is published twice a term. Activate is a free newspaper which receives an annual grant from the Rhodes University Student Representative Council, however, majority of its revenue is generated through advertising.

  • Description: Detention without trial can be a formidable government weapon against political opponents. In South Africa this weapon has been fashioned into a multiple warhead. There are currently seven security law detention provisions on the statute book, of which one is dormant but can be activated by the State President. Non security law detention, for example detention under drug laws, will not be discussed in this paper. While the seven detention laws are of varying severity and serve different purposes, they are best classified and explained under two main categories or groups - preventive detention and pre-trial detention.

  • 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

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.

  • Description: Cox et al. (1967) first delineated the existence of two major geochemical provinces in the Karoo basalts of southern Africa. Tholeiitic basalts in Zimbabwe are highly enriched in incompatible trace elements and constitute the "northern province". In contrast, basalts from Lesotho and from the southern segment of the Lebombo monocline have lower or “normal” abundances of these elements and were regarded as a "southern province'. Recent work has established that this change in composition takes place relatively rapidly in the Central Lebombo.

A phenomenological explication of the artistic creative experience of a painter, a writer and a playwright

- Lambie, Eileen

  • Authors: Lambie, Eileen
  • Date: 1988
  • Subjects: Phenomenology Art -- Philosophy Artists Creation (Literary, artistic, etc.)
  • Language: English
  • Type: Thesis , Masters , MSocSc
  • Identifier: vital:3115 , http://hdl.handle.net/10962/d1004605
  • Description: The aim of the thesis was to explore two focus questions using the phenomenological approach. Firstly, what it meant to be an artist for three particular artists; a painter, a writer and a playwright. Secondly, what a general explicitation (after Van Kaam, 1958) of the three subjects' artistic creative experience and working processes revealed in essence. The taped data of the three artists were reduced and explored through a number of phenomenological strategies. This led to the formulation of four essential descriptions for each artist, which were based structurally on Van den Berg's experiential categories in A Different Existence. Thus, the essential descriptions reflect each artist's relationship with his/her world, body, fellow people and time. The final step was the achievement of a general extended description. The major conclusion arising from the phenomenological explication is that art affords a way through which artists are able to live an authentic existence. That is, the body and world of the artist are in harmony and the artist's art roots him in the past, is manifest in the present and indicates the future direction of his work. Another conclusion is that the artist is Janus-faced and this enables him/her to balance subjectivity and objectivity in the Lebenswelt and to communicate what he/she sees to others in a healthy way through art. The artist's relationship with world, body, fellow people and with time, is postulated as being qualitatively richer than that of the nonartist. The two focus questions were successfully answered through the research explication and were validated by two independent judges. The viability of the phenomenological approach in the field of artistic creativity was therefore demonstrated. Suggestions for future research were made, one of which was that more phenomenological research aimed at eliciting specific information on the creation of art works might render more information on the artistic creative process.

  • Language: English
  • Type: Thesis , Masters , MA
  • Identifier: vital:3108 , http://hdl.handle.net/10962/d1004527 , Death -- Psychological aspects , Bereavement , Grief
  • Description: Bereavement is the natural human reaction to the death of a significant other. Often the experience of the bereaved person is denied expression in the social context. The aim of this thesis is to examine what it means to have one's bereavement denied by others. The relevant literature was reviewed. Theories which have both reflected and influenced the way the bereaved are perceived in contemporary western society have been discussed. The historical background to changing attitudes towards death was described and the reasons for the "denial of death" were examined . The narcissistic personality in particular was considered . Using the Phenomenological method, a question was formulated to elicit the lived structure of the experience being researched. This was asked of thirteen voluntary subjects who had experienced the denial of their bereavement by others. Five written answers (protocols) were chosen and explicated. The lived structure of the experience can be described as "a profound and fundamental distancing of the world of the bereaved from the world of others." The implications of this for the bereaved person, bereavement support groups, health care professionals, future research and society as a whole were then critically discussed .

  • 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: This thesis attempts a synthesis of two important and fast developing branches of mathematics, namely universal algebra and fuzzy set theory. Given an abstract algebra [X,F] where X is a non-empty set and F is a set of finitary operations on X, a fuzzy algebra [I×,F] is constructed by extending operations on X to that on I×, the set of fuzzy subsets of X (I denotes the unit interval), using Zadeh's extension principle. Homomorphisms between fuzzy algebras are defined and discussed. Fuzzy subalgebras of an algebra are defined to be elements of a fuzzy algebra which respect the extended algebra operations under inclusion of fuzzy subsets. The family of fuzzy subalgebras of an algebra is an algebraic closure system in I×. Thus the set of fuzzy subalgebras is a complete lattice. A fuzzy equivalence relation on a set is defined and a partition of such a relation into a class of fuzzy subsets is derived. Using these ideas, fuzzy functions between sets, fuzzy congruence relations, and fuzzy homomorphisms are defined. The kernels of fuzzy homomorphisms are proved to be fuzzy congruence relations, paving the way for the fuzzy isomorphism theorem. Finally, we sketch some ideas on free fuzzy subalgebras and polynomial algebras. In a nutshell, we can say that this thesis treats the central ideas of universal algebras, namely subalgebras, homomorphisms, equivalence and congruence relations, isomorphism theorems and free algebra in the fuzzy set theory setting

A survey of San paintings from the southern Natal Drakensberg

  • Description: From Introduction: The study of San rock art has undergone several different phases in approach to the interpretation of art. Two approaches are currently in use. The first emphasises the art as narrative or literal representations of San life and its proponents may be called the "art for art's sake" school. Adherents to the second approach make detailed use of the San ethnography on the belief system of these people and are highly critical of the literalists because they provide no such context. The second approach has rapidly gained ascendancy and replaced the "art for art's sake" school over the last twenty years. The watershed came with the researches of Vinnicombe (1967) in the southern Drakensberg and Maggs (1967) in the Western Cape who both embarked upon programs of research which had quantification and numerical analysis at their core, so that they could present "...some objective observations on a given sample of rock paintings in a particular area..." in order to compare and contrast paintings from geographically different areas. What Vinnicombe's numerical analyses clearly showed was that the eland was the most frequently depicted antelope and that it must have played a fundamental role "...in both the economy and the rellgious beliefs of the painters...", which opened up the search for what those beliefs might be and how they could be related to the rock art itself. In order to understand what the rock art was all about it was recognised that researchers had to meaningfully contextualise the art within the social and religious framework of the artists themselves. Without the provision of such a relevant context, as many different interpretations of the paintings could be made as there were people with imaginations. Such a piecemeal approach provides a meaningless jumble of subjective fancy which tells us something about the interpreters but nothing about the rock art. It is unfortunate that the advent of this explicitly social and anthropological approach marks the end of the amateur as a serious interpreter of San rock art, for the juxtaposition of the ethnography with the rock art requires a proper training in which the intricacies of symbol and metaphor can be recognised.
