Description: The Alternative Information and Development Centre (AIDC) and the NGO Coalition have called upon the new democratic government of South Africa not to pay the apartheid debt, incurred by the previous regime. The Reconstruction and Development Programme is suffering under the weight of interest payments on the debts made by the apartheid regime. Our organisations have argued that this debt is an odious debt incurred in the process of maintaining the system of apartheid. While major organisations of civil society have shown great interest in this issue, business and government circles . have been sceptical. A consistent concern has been raised in relation to the impact of debt cancellation for state pension holders.

Description: The principle aim of this study was to isolate a chemical for the "safe anaesthesia" of abalone under commercial farming conditions. "Safe anaesthesia" implied that the anaesthetic had no immediate detrimental or long term sublethal effect on the abalone, that it was safe for the farmer, the consumer and the environment. Four chemicals, magnesium sulphate (MgS0₄), ethylenediamine tetra-acetic acid (EDTA), 2-phenoxyethanol and procaine hydrochloride were shown to effectively inhibit the in vitro contraction of isolated tarsal muscle of Haliotis midae. This identified them as potential anaesthetics for abalone. Since abalone, like any other aquaculture species, would be subject to frequent size-sorting during the grow-out period, size related dosage tables were developed for the four chemicals at a temperature of 18⁰C. Dosage tables were also developed for benzocaine and carbon dioxide (C0₂), Three size classes (5-15, 20-50 and 60-90 mm shell length (SL)) of abalone were considered. Only three of the six chemicals, viz. MgS0₄, 2-phenoxyethanol and CO₂, met the criteria of an effective abalone anaesthetic in that they effected rapid and mortality-free anaesthesia. The other three chemicals caused mortalities and were considered to be unsuitable for commercial scale anaesthesia. Temperature related dosage tables were then developed for MgS0₄ and CO₂, MgS0₄ concentrations and CO₂ flow rates for effective anaesthesia in abalone were found to be inversely related to temperature. The three size classes of H. midae were intermittently exposed to MgS0₄ and 2-phenoxyethanol anaesthesia for an eight month period to determine the effect of the anaesthetics on growth rate. Because of an increased resistance to the efficacy of 2-phenoxyethanol and high monthly mortalities it was concluded that this chemical was unsafe and unsuitable for commercial use. MgS0₄, on the other hand, had no effect on growth of abalone and no significant effect on the rate of mortality. MgS0₄ also had no measurable effect on H. midae muscle ultrastructure and, by implication had no effect on flesh texture. The use of MgS0₄ as an anaesthetic would, therefore, not affect marketability. Moreover, no magnesium residues were found in H. midae muscle tissue after short term or intermittent long term exposure to MgS0₄ anaesthesia. It was found that the three size classes of H. midae used in this study could be safely exposed to the recommended MgS0₄ concentrations for up to 40 minutes without any mortalities. This is more than adequate for routine farming procedures. Medium size abalone (20-50 mm SL) were also safely exposed to 14 g.100 ml⁻¹ MgS0₄ for up to 6 hours without any mortalities. The results have shown that MgS0₄ was undoubtedly the best chemical that was evaluated for anaesthesia of H. midae in this study. It fulfils the requirements set forth by the U.S.A. Food and Drug Administration (FDA) in that it is safe for the abalone, the farmer, the consumer and the environment.

Description: This study aimed at investigating the relationship between adolescent parasuicide, depressive illness and associated risk factors. Reports worldwide indicate that suicidal behaviour in this age group has risen 150% over the past 20 years, whilst the rate for suicide in adults and the elderly has remained the same (Deykin et al, 1985; Neiger & Hopkins, 1988; Sudak, Ford & Rushforth, 1984a). In South Africa statistics confirm similar trends with regard to attempted and completed suicide. Statistics reveal that a high local incidence of adolescent suicide attempters are seen at psychiatric units. One pilot study recorded 187 adolescent suicide attempters during a three month period. This study was based on the hypothesis that the incidence of depressive illness in adolescent suicide attempters is higher than is generally accepted and that this condition often goes unrecognised and is misdiagnosed because it manifests differently with acting out behaviour and "masked" symptomatology. A random sample of suicide attempters between the ages of 13 - 25 who presented at C23 (psychiatric emergencies) Groote Schuur Hospital following a suicide attempt were assessed. 100 subjects were seen over a period of three months. The research procedure comprised a comprehensive assessment incorporating a semi-structured interview, self-report and objective rating scales for depression as well as instruments designed to assess the general health of each subject and their level of suicide intent. The depressive inventories used have been validated for use in this age group and were designed to elicit the associated features of adolescent depression. If warranted, a clinical diagnoses was given based on DSM 1V criteria. This diagnosis was substantiated by information from the research instruments which formed part of the assessment process. A high incidence of clinical disorders was diagnosed in the sample (86%). Depressive illness was found to be a significant risk factor for suicidal behaviour with 68% of the subjects suffering from an affective disorder and 21% reporting depressive symptoms. This study shows that the correlation between parasuicide and depressive illness is high enough to suggest that all suicidal behaviour in this age group should be taken seriously as parasuicide in itself is often a reliable indicator of an underlying depressive condition. Additional risk factors for adolescent parasuicide identified in this study correlated well with the findings of similar research studies. Psychiatric co-morbidity, especially substance use (42%) and cluster B personality factors (54%), were high and served to increase an individual's vulnerability to suicide risk. Psychosocial factors such as sexual abuse (28%) and physical abuse (37%) were also identified as high risk factors for adolescent suicidal behaviour. Individuals at risk for depression and suicidal behaviour typically came from broken homes which were disrupted and unsupportive. Family members were frequently abusing alcohol and 67% of the subjects reported the presence of psychiatric illness in the family. The preferred method of suicide attempt was an overdose (90%). These attempts were generally unplanned and impulsive with no disclosure prior to the event. Intent was usually high at the time of the act. It is only through identifying the risk factors specific to the developmental concerns of this age group and acknowledging the role of depressive illness in adolescent suicidal behaviour that effective preventative measures can be devised.

Description: First Year College of Education students who have done and/or passed mathematics at matric level, often lack adequate understanding of basic mathematical concepts and principles. This is due to the fact that formal tests and examinations often fail to assess understanding at anything but a basic level. It is against this background that this study uses alternative and more direct means of assessing the level and nature of the understanding such students have of aspects of basic arithmetic and number theory. More specifically, the goals of the study are: 1. To determine the students' levels of understanding of the following number concepts: Rational numbers; Irrational numbers Real numbers and Imaginary numbers. 2. To determine whether the students understand the rules governing operations with negative numbers and with zero as principles rather than conventions. 3. To determine whether the students understand the rule governing the order of operations as a matter of convention rather than as a matter of principle. A survey of the literature concerning the nature of understanding as well as the nature of assessment is given. The students' understanding in the above areas was assessed by means of a written test followid by interviews. A sample of 50 students participated in the study while a sub-sample of 6 were interviewed. Some of the significant findings of the study were : 1. The students largely failed to draw clear distinctions between Real and Rational numbers as well as between Irrational and Imaginary numbers. 2. Very few of the students could explain the rationale behind the rules governing the. operations with negative numbers and zero. 3. Only half of the students had any knowledge of the rule governing the order of operations. Only one student demonstrated an understanding of the rule as a convention.

Description: This study looks firstly at the historical background to conservation, particularly in the South African National Parks Board, and relates this to developments in interpretation in the National Parks. These are evaluated against international norms as they appear in the current literature. The aim is to establish a platform upon which future developments in interpretation may be built, avoiding the mistakes of the past, while capitalising on the strong points. Current views of what interpretation is, and what it should be, are reviewed. Knowing who the audience is, in terms of cultural background, education, needs and interests, as well as sound planning, clear objectives and ongoing evaluation of interpretive programmes, emerge as essential prerequisites for effective interpretation. Through reviewing the development and current status of interpretation in the National Parks, the study finds that although the view has been expressed by management, both past and present, that interpretation in the national parks is of great importance, the past and current status of interpretation does not reflect that view. Generally, interpretation appears to be regarded as a non-essential service. This report argues that environmental interpretation should be given a higher status in the National Parks Board and that it should form an important part of the conservation strategy and management plan for the national parks. The researcher contends that a greater investment in interpretation could lead to a decrease in the need for further, increased investment in law enforcement in the parks. The researcher is also of the opinion that interpretation aimed at all levels of personnel of the National Parks Board is at least as important as interpretation aimed at visitors.

Description: There are few female teachers who hold principal positions in schools, especially in secondary schools. This study investigates teachers' perceptions of secondary school female principals' leadership abilities and styles.It also investigates whether teachers' perceptions are influenced either by their sexes or experience or lack of experience of working with female principals. The reseacher hopes that this research findings will help to either: develop and improve female leadership (where it is found to be wanting); and or influence authorieties to appoint more female teachers to head secondary schools. The literature surveyed revealed that the appointment of principals in seconday schools is discriminatory against female teachers. It further revealed that principals (mainly male) do not prepare female teachers for management and leadership positions. As a result female potential leaders become demotivated. This is unfortunate as research has found that female principals are as effective as leaders as male principals are. One disadvantage of having a small number of female leaders in education is that this results in an education that only reflects the male perspectives and values. This in turn alienates girls' perspectives from education. In order to establish teachers' perceptions of female secondary school principals a survey of the percptions of teachers in the Maphumolo circuit of female principals in this area was first carried out by means of a questionnaire. This was followed by a case study of one female principal. In depth, semi-stuctured interviews were undertaken with the principal and three teachers working with her in order to establish this principal's leadership style and the teachers' feelings towards her. A statistical analysis of the survey and a conten~ ~alysis of the case study were carried out. These revealed that the majority of teachers perceive female principals as effective and transformational leaders. These perceptions were found to be minimally influenced by either the teachers' sexes or experience of working with female principals. The..majority of those teachers who perceived female principals negatively tended to be males and to be from a group of teachers who had never worked with female principals. Recommendations for the increase of the number of female principals in secondary schools and for the improvement ofleadership in these schools are made.

Description: This thesis describes the evaluation of several proposals suggested as replacements for the currenT Internet's TCPJIP protocol suite. The emphasis of this thesis is on how the proposals solve the current routing and addressing problems associated with the Internet. The addressing problem is found to be related to address space depletion, and the routing problem related to excessive routing costs. The evaluation is performed based on criteria selected for their applicability as future Internet design criteria. AIl the protocols are evaluated using the above-mentioned criteria. It is concluded that the most suitable addressing mechanism is an expandable multi-level format, with a logical separation of location and host identification information. Similarly, the most suitable network representation technique is found to be an unrestricted hierarchical structure which uses a suitable abstraction mechanism. It is further found that these two solutions could adequately solve the existing addressing and routing problems and allow substantial growth of the Internet.

Description: The purpose of this study is to look at how the figure is imaged through the photographic medium today. Through this purpose I aim to explore the individual expression of the photographer in his photographic medium; the expression of the figure within the medium and the diverse practises of this medium in society - to build up an awareness and understanding of the diverse representations of the human form. The general aims of study are: 1 - to study how these three photographers choose to photograph the figure, through their technical, compositional and individual approach. 2 - to show how diverse the usage of the photographic figure is in the visual world. 3 - to expose an awareness of the photographic figure as transformation of an expression of self. 4 - to show the relationship between the photographer and the figure, the camera and the photographer, the camera and the figure, and the photographic figure and the viewer. 5 - to study my own photographic imagery in relation to the other imagery discussed. My research information was collected through: observations, discussions, literature and practical exploration. This study will attempt to draw conclusions, from its explorations, that will highlight the importance of the individual eye: that it is the individual eye that becomes the vehicle of transformation.

Description: Digital geographical information systems (GIS) are tools for handling spatial data. Initially developed in First World countries, the technology is fast being taken up as a tool for handling spatial information by many Third World countries. GIS has been used for any number of applications involving spatial data, one of its primary uses has been in various planning fields where the advantages offered to planners by the technology have been highlighted by a number of publications and studies. GIS has been actively used as an urban planning tool in South Africa since the mid-1980s, (Vosloo 1987) however its use as a tool for rural planning has not developed to the same extent. As early as 1986 reference was made to the possible advantages offered by GIS to rural planning in South Africa (Fincham 1986). Despite this early recognition, the use of GIS in the rural planning sphere remains negligible. This study examines the. possible reasons for this by attempting to answer the question, "is GIS appropriate to rural planning in South Africa?" A number of approaches to rural planning are practised in South Africa. This study examines the appropriateness of applying GIS to one of these approaches, rural community development planning. Components of the study included i) an examination of the issues affecting the use of GIS in the rural development field, achieved through the use of a literature and questionnaire survey and ii) a case study examining the feasibility of incorporating GIS as a tool to the Shixini Development Project, Transkei. The study does not examine the intricacies of rural development theory, but it does acknowledge the fact that the approach employed by an organisation to rural development will have important implications concerning the use of a GIS in a project. The approach adopted to a project affects amongst others the administrative structure, the planning process, the flow of spatial data and its use, and consequently the possible role of GIS. The Shixini Rural Development Project was classified as a community development project, and as a result the study concentrates on this approach to rural development. This may limit the study to a particular planning process, however most rural case studies will have certain aims and factors which are unique to its situation. In order to place the results of the Shixini case study in a wider context the results of the study are linked to the questionnaire and literature survey. From this basis the usefulness of GIS in the rural development sphere was examined. Available literature on GIS indicates that the majority of problems associated with GIS rarely reside with the technology itself but rather with its supporting mechanisms. The study identified and concentrated on these support mechanisms, both at the project level and what is referred to in the study as the operating environment in South Africa. The results of the study revealed that a number of problems exist with regard to the attitude with which GIS is regarded in development organisations. It was found that these attitudes are legitimately based on a number of problems associated with incorporating the technology into project based organisations. It was concluded that GIS was appropriate to rural community planning, but is presently limited to certain aspects of the planning process and possibly to certain applications.

An examination of dreams and visions in the novels of Virginia Woolf

Description: This thesis explores the importance of the visionary experience in five novels by Virginia Woolf. In her fiction, Woolf portrays the phenomenal world as constantly changing and she uses the cycles of nature and the passing of time as a terrifying backdrop against which the mutability and transience of human life are set. Faced with the inevitability of change and the fact of mortality, the individual seeks moments of permanence. These stand in opposition to flux and lead to the experience of a visionary intensity. Woolf's presentation of time as a qualitative phenomenon and her stress on the importance of memory as a function which allows for the intermingling of past and present make possible the narrative rendering of moments which contradict perpetual change and the rigours of sequential time. Moments of stillness 'occur in the midst of and in spite of process and allow for individual contact with an experience that defies the relentless progression of time. Necessary for this experience is not only memory but also the imagination, a faculty which has the power to perceive patterns of harmony in the midst of the chaos that characterises the phenomenal realm. Fundamental to Woolf's writing, however, is the acknowledgement that visions are fleeting, as are the glimpses of meaning that emerge from them. Therefore, while several of her novels describe the artistic effort to create a structured order as a defense against change, Woolf uses the artist's struggle as a metaphor for the difficulties attached to describing the enigma that is life. None of her artist figures is able to formulate a construction that either sums up life or provides a permanence of vision. This study presents a chronological examination of the novels in order to demonstrate that the changing forms of Woolf's fiction trace the evolution of a style that accurately portrays both the workings of the human mind and the insubstantial and fragmentary nature of life. The chronology also reveals that her novels develop in terms of their presentations of the visionary experience. Woolf's final novel incorporates into its central vision the paradoxical fact of the permanence of time's progression and acknowledges that, beyond the individually mutable life, is a continuum that links pre-history to the future. This notion, which is explored in part in the earlier novels, but developed completely in Between the Acts, suggests that consolation can be found in the greater cycles of existence despite the fact of individual mortality.

Description: This study aims to explore, and to a certain extent to clarify, what it means psychologically to experience Traumatic spinal cord injury (TSCI) in a South African spinal unit. The target time chosen for analysis is the acute medical period. The study presents a review of the literature on psychological adjustment to TSCI and then proceeds to introduce and extensively articulate the hermeneutic approach and methodology. Subsequently, an interpretive research strategy is presented for the purpose of studying the acute phase of TSCI. The data for the study was obtained by means of three dialogical interviews which were tape recorded, transcribed and analyzed with~n a cyclical framework consisting of three interdependent levels. The interpretive procedure is modeled upon the 'reading guide' developed by Brown, Tappan, Gilligan, Miller and Argyris (1989). The analysis follows a course from the individual psychological descriptions of the experience to the generation of a general, nomothetic narrative account of the acute phase. The findings are then discussed in relation to the existing literature and evaluated on the basis of the goals of the study. The study highlights the value of some of the 'stage' ways of thinking about SCI adjustment, while simultaneously stressing the need for placing adjustment within a more personalized, and individually meaningful context. Significant differences between the psycho-physical experiences of patients in the categories of complete and -incomplete SCI were found, which suggests that a sharper distinction be made in the literature between these two groups, in order to account for the marked variations in their experiences.-- The study also contains a number of shortcomings, such as a lack of understanding about certain historical and contextual factors which may have mediated the experiences of the trauma for the individuals concerned. These shortcomings and some suggestions fro their resolution are then discussed. The study concludes with an evaluation of the research strategy and methodology and also offers some suggestions for future research.
