- Description: This project uses the case-study method to illustrate the application of integrating varied accepted modes of psychotherapeutic interventions. It concentrates on the first 22 out-patient sessions of therapy with a diagnosed bulimic, spanning a 6 month period. A brief summary of the subsequent 10 follow-up sessions is also given. The case presented is of a 22 year old female student diagnosed as bulimic (of 7 year duration), dysthymic and with a dependent personality disorder. She has symptoms of anxiety. She has a history of anorexia nervosa. Fairburn's (1985) cognitive-behavioural programme for bulimia was used initially. Its structured framework with the emphasis on the eating behaviour was an essential aspect in contributing to the success of the initial phase of the therapy. This patient had had previously experienced 8 sessions of non-directive depth psychotherapy which had confused and compounded her problems. The structure had provided her with a sense of control. In implementing the second stage of Fairburn's programme, where the focus is cognitive, the patient could no longer work in this this structured manner. The attempts to implement the standard cognitive techniques provided the catalyst for activating deeper underlying emotions and cognitions. Furthermore, this gave impetus to work actively with the interpersonal aspect of the therapeutic relationship. Young's (1989) model for identifying Early Maladaptive Schemas could be applied. The focus then moved from the behaviours and dealt with these schemas as activated in the therapeutic relationship. The patient was able to make links to her family and her past. The therapy proved successful, as not only were the behavioural symptoms alleviated, but also the patient's interpersonal problems which underlay her personality disorder were accessed. The patient had become more self-assertive, her mood had improved considerably, she was less concerned with body image and more accepting of herself. She had become more reality based and her interpersonal relational abi1ity had improved. , Thesis (MA) -- Faculty of Humanities, Psychology, 1990

- Description: This study comprises a dialogue between Gendlin's recommendations on the treatment of the silent patient and case-material taken from 39 sessions of psychodynamic psychotherapy with a 16 year old adolescent. The most characteristic feature of the therapy with this young person, was her pattern of silence and unresponsiveness. The aim of this study is to ascertain the usefulness of Gendlin's recommendations in the therapy of this category of patient. The dialogue between the suggested recommendations and the case- material served to illustrate the point that Gendlin's recommendations are of great value in the treatment of the silent adolescent. The value of these recommendations lie in their ability to comment meaningfully on the process of therapy with the silent patient by providing not only skills and techniques, but also a conceptual framework within which to contextualize the therapy. The recommendations were also found to be sensitive to some of the key issues of relevance to adolescence as a developmental phase. The case-study method was deemed an appropriate structure within which to conduct this examination. , Thesis (MA) -- Faculty of Humanities, Psychology, 1990

- 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

This investigation and analysis is conducted within the framework of a phenomenological method. The researcher elicits both the ex-detainees' and the therapist's experiences of psychotherapy. Initially the problematic nature of research in psychotherapy is layed out. This is followed by an overview of literature and theory on trauma and its conceptualizations from various psychotherapeutic perspectives. The treatment implications in each case are mentioned. Trauma occurs in the detention experience so detention is then briefly looked at in terms of torture basically and the detention syndrome, post traumatic stress disorder. Core personality processes in relation to this diagnosis are given and the stress recovery process is summarized. , Thesis (MA) -- Faculty of Humanities, Psychology, 1988

- Description: The aim of this project is to come to an understanding of how the situation of the first session of psychotherapy with the first patient is lived by the beginning therapist and what meaning this situation holds for him. The writer's interest in this phenomenon grew out of her own experience of this situation as a clinical Masters coursework student, an experience which was of important to the writer and meaningful still as a therapist in training. In dialogue with experienced therapists the importance of this situation was again made apparant. It was the opinion of these therapists that although for some the details of this experience had become dulled by time, what remained meaningful to them was that this experience was seen as the beginning of a project which remains important to them - they identified this situation as an important moment in the history of their development as psychotherapists. In the hope that the literature pertaining to psychotherapy would throw some light on this situation, the writer turned to a number of sources in this area to discover that no literature available to her elucidated this situation in a holistic manner. This led the writer to go back to the beginning therapists themselves so that they may speak for themselves of their experience of this situation. A phenomenological method of enquiry is implemented in this study as it renders the subject matter accessible to investigation, and allows it to reveal itself as it essentially is. This project is then an attempt to come to a general description of the beginning therapist's experience of the first session of psychotherapy with the first patient and thus to articulate the structure of the beginning therapist's lived situation (world) in this context. , Thesis (MA) -- Faculty of Humanities, Psychology, 1987

- Description: This introduction and ensuing essay are something in the nature of a personal confession. Deemed as such what I have written concerning Samuel Palmer has not, in any way, been written as an exercise, but rather for the purpose of self-edification. This I will elaborate upon while disclosing my motive for writing on Palmer. Palmer's works - when I first saw them - were something of a revelation. They seemed the alpha and omega of my own artistic endeavour. Perhaps the term which best describes the euphoria I felt is 1deja vu1, because although it describes a connectedness of sorts, the words have in their sound an exotic ring. There is in it an implied equivocation - and equivocality best describes my understanding of Samuel Palmer at that juncture. This euphoria I felt dimmed with the realisation that by purportedly claiming, as I was, Samuel Palmer's visionary landscapes as my goal I was treading on sacred ground; I'd arrived, as it were, in another's Paradise. The effects of this upon my own creativity were completely negative. Worse still, I lacked the necessary means to extricate myself from Palmer's paradisiacal visions. His influence was incapacitating and convoluting my own growth. It was obvious then that I had to be rid of Samuel Palmer. , Thesis (MA) -- Faculty of Humanities, Fine Art, 1985

- 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: The Department of Zoology at the University of Port Elizabeth has an ongoing programme on the Swartkops estuary with the eventual aim of drawing up the energy pathways of the system. Marais (1976) has investigated the nutritional ecology of the grunter Pommadasys cormersoni while Melville-Smith (1978) and Melville-Smith and Baird (1981) reported on the ecology of larval fish. Winter (1979) studied the ecological parameters of fish populations, but this work was not a detailed account of each population. Wooldridge (1979) studied components of the 3 zooplankton community in some detail. It became evident that there was a significant lack of understanding of the ecological relationships between plankton and piscivorous fish, which was crucial to the elucidation of the interactions and trophodynamics of the Swartkops estuarine system. Since G. aestuarius is an important link in the energy pathway from the plankton to the nekton, and in terms of numbers dominates the seine net catches made in the estuary (Winter, 1979), this study was motivated. The aim was to investigate the important biological parameters of the estuarine round herring population namely the population structure, distribution and abundance, individual growth rate from field data, the food and feeding habits, reproduction and respiration, all of which are essential for the understanding of the dynamics of a species. These parameters were later converted into energy terms and the construction of an energy budget was attempted. , Thesis (MSc) -- Faculty of Science, 1982

- Description: A well known fact about any work of art of any significance is its power to upset current conventions and disturb certain of our normal emotional patterns. The artist frequently achieves this by deliberately expressing emotions that are violent. There is nothing, however, new about the existence of violence in the arts, a large number of works in the history of art being painted with blood. One has only to think of the many battles, rapes, murders, martyrdoms and catastrophes that have been the subjects of many great paintings. Since the beginning of this century, and especially since the work of the Impressionists, in which violence is entirely excluded, violence has taken on a role of great importance and has been used to a greater or lesser extent by artists and group movements. It would appear initially that there are two main reasons in this century for the use of violence: one as a means of using it as a weapon against the academic and avant-garde in the arts, which in turn reflects attitudes found in society, and secondly as a direct reflection of the corrupt society in which we live. This is not to say that the twentieth century is an age in which more violence and sadism is found than in any other era of history, but never has it received so much publicity. I do not believe that man has change so much over the years, but it is my view that the apparent increase in this century is due to the vast changes in communications, it is due to the publicity it receives that violence has in recent times become a focal point, with murders, assassinations and war part of our daily lives. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 1971

- Description: This thesis describes the design and construction of a swept-frequency polarimeter for observing Jupiter’s decametric radiation in the frequency range from 15 to 45 MHz. The frequency band is tuned in two parts using two receivers for observing the left- and right-circular components of the radiation in the 15 to 26 MHz range and two receivers for observing the circular components in the 30 to 45 MHz range. The receivers are tuned electronically by means of varactor diodes and are of novel design in that they do not have any intermediate-frequency stages. The frequency band can be swept 10 times per second or 100 times per second. The antennas used for the polarimeter are helical beam antennas, two for each of the circular components in the 15 to 26 MHz range and two for the 30 to 45 MHz range. Model studies of the antennas were conducted to establish whether they have suitable characteristics for observing the polarisation of Jupiter’s decametric radiation over a wide frequency range. Many spectral records of Jupiter’s decametric radiation were obtained using a preliminary version of the swept-frequency receiver and a log-periodic dipole antenna. Some of the records are presented and one record which shows an interesting case of Faraday rotation is analysed. , Thesis (MSc) -- Faculty of Science, Physics, 1970

Some of the records are presented and one record which shows an interesting case of Faraday rotation is analysed. , Thesis (MSc) -- Faculty of Science, Physics, 1970

- Description: War is a condition of this world. From man to the smallest insect, all are at strife, yet man has a "quality which makes him overlord of all; for whereas the creatures of the forest and plain kill only to eat, or to lead the herd ... man will kill for no reason at all. This makes him terrible among the creatures, for he is the very God of Destruction. And from man's pride in his weapons that give him power has grown his art." Warfare in its primeval state is a direct result of a natural phenomenon, springing from the discovery that certain grass seeds could be cultivated and that certain grass feeding animals could be domesticated. From these roots sprouted two very differently organised communities, the agricultural and the pastoral, who clashed for the first time in the third millenium B.C. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 1968

- Description: In a paper entitled "Bacteria of the Soil", Dr. Russell of Rothamsted is quoted as saying, ”The top six lashes might almost be called a separate world? 80 great is the number and variety of its inhabitants”• It is with a few forms belonging to this enormous biological complex that the author intends to deal, viz*, representatives of the Orders Pauropoda, Symphyla, Protura, Coleoptera and Hemiptera. Time does not permit the inclusion of a study of the multitude of Arthropod, species that occur in the soil, but a more complete work on these soil groups is intended in the future. McCullogh and Hayes (1922,p.288) state that the soil is an integral factor In the study of biological problems. Hence an understanding of the organic life of the soil, which is of great importance in relation to the other aspects of pedology, is a necessary adjunct to the study of the soil ae a whole. , Thesis (MSc) -- Faculty of Science, Botany, 1947

- Description: Earthworms of the genus Microchaetus, Rapp.1849, are abundant in the Grahams town district. Microohaetus saxatilis, Rosa, 1S98,has been chosen as a subject for investigation as it is a valuable type for laboratory work, and it showed interesting characters which required detailed study. Members of the genus Micro chaet us are available in many regions of South Africa and are useful for work in South African schools and Universities. Micro chaetus saxatills is an 01igochaete worm belonging to the family Glossoseolecidae. These wonns were originally placed in the Lumbricina by Grube, (1850 p.345), but Rosa in 1887 (p.7) formed a separate family naming it the Geoscolecidae. He divided it into two sub-families :- (1) Geoscolecinae, and (B) Microchaetinae. Beddard was studying the classification of this family at the same time as Rosa. He spelt the name slightly differently, calling the family the Geoscolicidae, but he arrived independently at the same division into subfamilies (1888, pp. £43-278), although he suggests that perhaps an additional sub-family - the Homo gas. tridae - should be formed. Homo gas ter is undoubtedly an aberrant type, and it seems strange that Rosa who studied this genus should not have placed it in a separate sub-family. , Thesis (MSc) -- Faculty of Science, Zoology, 1941

- Description: This introduction and ensuing essay are something in the nature of a personal confession. Deemed as such what I have written concerning Samuel Palmer has not, in any way, been written as an exercise, but rather for the purpose of self-edification. This I will elaborate upon while disclosing my motive for writing on Palmer. Palmer's works - when I first saw them - were something of a revelation. They seemed the alpha and omega of my own artistic endeavour. Perhaps the term which best describes the euphoria I felt is 1deja vu1, because although it describes a connectedness of sorts, the words have in their sound an exotic ring. There is in it an implied equivocation - and equivocality best describes my understanding of Samuel Palmer at that juncture. This euphoria I felt dimmed with the realisation that by purportedly claiming, as I was, Samuel Palmer's visionary landscapes as my goal I was treading on sacred ground; I'd arrived, as it were, in another's Paradise. The effects of this upon my own creativity were completely negative. Worse still, I lacked the necessary means to extricate myself from Palmer's paradisiacal visions. His influence was incapacitating and convoluting my own growth. It was obvious then that I had to be rid of Samuel Palmer. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 1939

Soil erosion in South Africa

- Description: The development of Soil Science in western Europe, eastern North America, and later in other countries, which, in its modern form only started about the beginning of the last century, might be said to mark the first step in the consideration of Soil Erosion from a scientific aspect, although it was some time before scientists began to concentrate on and study the problem as one which demanded a detailed investigation. Empirically, erosion has been noted and, where the value of the land warranted it, practical methods adopted for its control, in many cases with no small measure of success, for centuries, but the methods adopted were localised to small regions, and the major destruction went on unchecked. The seriousness of this destruction was usually not realised until too late, and striking examples exist of the complete desiccation resulting from this neglect. Those of China, Arabia, Mesopotamia and other countries have often been quoted, and need not be described again here. , Thesis (MSc) -- Faculty of Science, Chemistry, 1936
