- Description: The motivation for this study was to examine the exploitation patterns of the M. capensis and M. paradoxus hake fisheries on the Southeast Coast, and determine the size and species of hake caught in each of the hand-line, long-line, and trawl methods. The handline hake fishery has increased substantially over the last several years and concerns are beginning to emerge about the impact this will have on the inshore resource collected on the South Coast between August 1998 and July 1999 was used to describe the hand-line method and estimate annual landings. Data on the size and species in longline catches of hake caught during 1997 were already available for this study. Size distributions in trawl catches were determined from commercial category landing data reported by catch weight and depth. The species composition in these catches determined by comparison using RV Afrikana survey data collected in the same depth regions. Location plays a significant role in determining the sizes and species of hake caught by each gear. Hand-lines catch smaller sizes on average than do long-lines, inshore trawls target mainly M. capensis while offshore trawls catch both hake species. A substantial amount of the hand-line hake caught on the South Coast is not reported. Examination of the exploitation patterns reveal that intense trawling pressure is directed at the smaller sized M. paradoxus inhabiting the depth region between 160-400-meters. Inshore trawls discard a large amount of small sized M. capensis within the 100-meter isobath. A preliminary stock assessment on the status of each hake species found that M. paradoxus appears to be over-exploited while M. capensis was in better shape. However, length-based pseudo-cohort analysis, used in this assessment, is critically reliant on having length frequency data from a steady state population in equilibrium. This limits the application of this model for management purposes and this finding is purely theoretical at this stage. Results suggest that each hake species is under a different pattern and level of exploitation and the multi-species nature of hake stocks on the South Coast should be considered in developing optimum management policies. Future work should focus on developing appropriate age/length keys so that an age-based VPA, which is more powerful than the length-based approach, can be applied towards stock assessments on the South Coast. Alternatively, length-data covering a longer period should be compiled and the equilibrium assumption further investigated so that the results from length-based models can be used with more confidence.

- Description: The aim of this research was to explore how participants made meaning in an environmental education and training course for people from industry, business and local government in South Africa, and to identify and comment on any constraints to this meaning-making. I used a Symbolic Interactionist theoretical framework to explore and comment on the meaning-making process. I started my research by conducting a questionnaire to select participants for interviews. During the course the selected participants were interviewed, as well as the two course co-ordinators. Data was also gathered during the course from participant observation field notes ('captured talk'), photographs, participants' assignments and course evaluations. The data was analysed using an adapted form of discourse analysis and matrices. The research highlights that the opportunities provided on the course were adequate for encouraging meaning-making amongst both the co-ordinators and participants. However, recorded instances of meaning-making were low, which indicated that there were certain constraints during the meaning-making process. This research highlights and comments on identified constraints such as time and workplace support. The research supports similar findings which emerged from research conducted on the Gold Fields environmental education course for teachers and also offers recommendations for further research and practice into meaning-;making within the field of environmental education and industry, business and local government in South Africa.

- Description: During this research an attempt was made to gain an understanding of the experiences and needs of the social workers acting as intermediaries for the sexually abused children in the criminal court during the trials of perpetrators. To achieve this, ten social workers that have performed the role of intermediary were interviewed. Research as well as literature on this topic is limited and it is believed that this study will present a valuable basis to pursue in further research as well as assist social workers already rendering intermediary services. Literature that was available was found to be critical of the adversarial system and the negative elements associated with the system, especially for the child witness. The study found that there are many problems associated with the intermediary system. The most important issue is the delay between the decision to prosecute and the trial as this impacts negatively on the child witness. In addition social workers acting as intermediaries are inadequately trained and are not supervised in this role. As a result very few are willing to continue with the procedure. Nevertheless the intermediary system is adjudged better than the adversarial system, especially as the child witness no longer has to face the alleged perpetrator in an open court. The thesis ends with recommendations for addressing the concerns of intermediaries in order to strengthen the system.

- Description: The feeding biology of three euphausiid species, Euphausia vallentini (adults and juveniles), E. longirostris and Nematoscelis megalops was investigated during austral autumn (April/May) of 1998 and 1999, in the vicinity of the Prince Edward Islands (Southern Ocean). Data on the abundance and biomass of these species, estimated from bongo net tows, were investigated. Trophic position was assessed using gut contents and stable nitrogen isotope measurements. Feeding rate and daily carbon ration were estimated using the gut fluorescence and the gut fullness techniques. Vertical migrations into the surface waters at night were found to be strong for Euphausia vallentini adults and juveniles. Associated with these migrations were clear diel feeding patterns. Insufficient data during daylight hours for E. longirostris made it impossible to determine diel feeding patterns, but high feeding activity did occur during dark hours. Nematoscelis megalops did not show any distinct diel feeding pattern, but slightly higher gut fullness indices in the late afternoon suggested that feeding activity may have been highest during this period. For both Euphausia spp. high gut pigment levels were recorded in 1999, which corresponded to higher ambient chlorophyll a concentrations for that year. Highest initial gut pigment levels and highest ingestion rates were found for Euphausia longirostris in both years and lowest values were observed for N. megalops. High phytoplankton and low metazoan contributions to the diet of Euphausia vallentini juveniles, as shown in the gut content analysis, and low stable nitrogen isotope ratios (ð¹⁵N = 1.39±0.31), both indicated that this group was principally herbivorous. The results of gut content analysis of the adults of E. vallentini were similar to those of the juveniles, however, stable nitrogen isotope results showed that there was a higher degree of omnivory (ð¹⁵N = 3.81±0.66). Daily ration estimates from the gut fluorescence and fullness techniques showed that between 3.3 and 25.7 % of E. vallentini adults total daily carbon ration was derived from autotrophic sources. Although the contribution of carnivory to the diet was difficult to determine, the adults of this species may be considered omnivorous. Irrespective of the degree of carnivory, a dietry shift with an increase in size was evident for this species. Gut content analysis for Euphausia longirostris showed that this species consumed large amounts of both phytoplankton and metazoan prey and this was reflected in the stable nitrogen isotope results (ð¹⁵N = 6.88±0.60). These findings were supported by the results of the daily carbon ration estimates which showed that autotrophic carbon contributed between 6.9 and 20.3 % of the daily carbon consumption. The gut content analysis suggested that N. megalops was omnivorous, and the stable nitrogen isotope results place it in a trophic position equivalent to that of E. longirostris (ð¹⁵N = 6.83±0.78). Calculations from daily ration estimates suggested that only 3.1 % in 1998, and 3.2 % in 1999, of the carbon ingested was of autotrophic origin. This species may therefore be considered carnivorous. Implications of the findings of this study are discussed in terms of carbon cycling in the Southern Ocean.

- Description: Many well-known studies on leadership have ignored the perspective of women yet bear an emphasis on the importance of portraying leadership in its entirety. This would mean that all leadership perspectives are included and that leaders are allowed to speak for themselves and about themselves. It is this connection I have sought to establish how women perceive leadership by relating the experiences of four women in school principalship. I have used a factual questionnaire to establish the background of each one but, it is the in-depth interviews that yield the leadership perceptions. Borrowing from phenomenological procedures, the leadership experiences are related as Natural Meaning Units (NMUS) whereby all prior knowledge and possible bias are bracketed out. Reinforced by their journal entries, it is only the voice of the women that is heard. My study reinforces the observation of researchers and feminist scholars that women leaders are not only marginalised but also viewed from a perspective that is not their own. From the study, however, the one element about leadership that emerges as unique is the functioning of transformational leadership elements among women leaders in educational set-ups that are inherently traditional, bureaucratic and hierarchical. This is significant because there is an indication that women leaders are inclined to transformational leadership because it favours their feminine qualities. There is also evidence that school principals can embrace leadership diversity and finally, that leadership and the structures of leadership operation are not developed from without but from within the person of the leader and this is an incorporation of their vision and beliefs. In the context of South Africa, this study should be of potential significance because of the change that is taking place in the development and training of school principals.

- Description: Objects in a virtual world can be converted into hardcopy by per-pendicular projection of each face onto a sheet of paper, cutting and gluing. Previously, use of this technique was restricted to a limited class of polyhedral objects. This paper extends this process to realis-tic virtual objects, with the traditional origami restriction of using only a single sheet of paper. A number of algorithms are explored to achieve this goal. The use of heuristics allows solutions to be found without exhaustive search of all possible layouts. Approaches to deal with pathological cases are described. The techniques have al-ready been successfully applied to a number of complex models, selected from a number of model archives on the Internet.

- Description: The technology revolution has transformed the way in which many organisations do their business. The resultant information systems have increased the decision making powers of executives, leading to increased effectiveness and ultimately to improved product delivery. The process of information systems development is, however, complex. Furthermore, it has a poor track record in terms of on-time and within-budget delivery, but more significantly in terms of low user acceptance frequently attributable to poor user requirements specification. Consequently, much attention has been given to the process of requirements elicitation, with both researchers and businessmen seeking new, innovative and effective methods. These methods usually involve large numbers of participants who are drawn from within the client and developer organisations. This is a financially costly characteristic of the requirements elicitation process. Besides information systems, the technology revolution has also brought sophisticated communication technologies into the marketplace. These communication technologies allow people to communicate with one another in a variety of different time and space scenarios. An important spin-off of this is the ability for people located in significantly different geographical locations to work collaboratively on a project. It is claimed that this approach to work has significant cost and productivity advantages. This study draws the requirements elicitation process into the realm of collaborative work. Important project management, communication, and collaborative working principles are examined in detail, and a model is developed which represents these issues as they pertain to the requirements elicitation process. An empirical study (conducted in South Africa) is performed in order to examine the principles of the model and the relationships between its constituent elements. A model of geographically distributed requirements elicitation (GDRE) is developed on the basis of the findings of this investigation. The model of GDRE is presented as a 3-phased approach to requirements elicitation, namely planning, implementation, and termination. Significantly, the model suggests the use of interviews, structured workshops, and prototyping as the chief requirements elicitation methods to be adopted in appropriate conditions. Although a detailed study of communications technology was not performed, this thesis suggests that each individual GDRE implementation requires a different mix of communication technologies to support its implementation.

Important project management, communication, and collaborative working principles are examined in detail, and a model is developed which represents these issues as they pertain to the requirements elicitation process. An empirical study (conducted in South Africa) is performed in order to examine the principles of the model and the relationships between its constituent elements. A model of geographically distributed requirements elicitation (GDRE) is developed on the basis of the findings of this investigation. The model of GDRE is presented as a 3-phased approach to requirements elicitation, namely planning, implementation, and termination. Significantly, the model suggests the use of interviews, structured workshops, and prototyping as the chief requirements elicitation methods to be adopted in appropriate conditions. Although a detailed study of communications technology was not performed, this thesis suggests that each individual GDRE implementation requires a different mix of communication technologies to support its implementation.

- Description: The aim of this brochure is to provide a reasonably comprehensive guide to Grahamstown and its environs. The area has much to offer the person who is prepared to explore and to observe the many facets offered by the human and physical landscapes. It is hoped that the sections on the development of the town and selected historical aspects, the geology, the vegetation, the mammals and the birds will provide sufficient information for the region to be seen and appreciated as a whole, while still leaving room for new discoveries. The interrelationships between geology, altitude, vegetation and the use of the land form a valuable starting point in the study of the countryside. In the towns the buildings and the street grids often help to unravel complex aspects of growth and development. These are some of the features which can be observed on the recommended excursion routes. If the brochure contributes to a greater understanding, and therefore appreciation, of Grahamstown and its environs its purpose will have been fulfilled. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

- Description: Cross-border conflicts on the African continent have increased tremendously in the post-colonial years. The widespread border conflicts on the African continent have been attributed to the arbitrariness with which Africa’s national boundaries were drawn during the colonial period. The colonial boundaries have left the doors open for perpetual conflicts among African states. This thesis proposes to investigate the prospects of grassroots diplomacy as an option of dealing with border conflicts with specific reference to the case of Lesotho/South Africa border relations. This is done by critically evaluating the role the District Liaison Committees (DLCs) have played in border relations between Lesotho and South Africa. The Lesotho and South African governments have institutionalised the resolution of border conflicts at grassroots level through the establishment of the DLCs. The DLCs consists of representatives of border communities in Lesotho and South Africa. The paper introduces a not so familiar concept of involving people at grassroots levels in the conducting of diplomacy between the two neighbouring countries. The central issue implicit in this paper is that grassroots diplomacy is succeeding in the case of Lesotho and South Africa. The DLCs have managed to reduce tension between the two countries along the borders which had existed over a long period of time, thereby, relieving the central governments of some of their duties. The thesis contents that high level conventional diplomacy is not always the answer to cross-border conflicts. The example of Lesotho and South Africa could be followed by other African countries in similar situations.

- Description: A handheld InfraRed (IR) Carbon Dioxide (CO2) gas detector was developed and used to carry out a study of water and urine samples in South Africa. The details of the model and the results of the study are discussed here. The overseas markets are not geared for the current South African conditions. Use is made of components that can be obtained locally. Imported components are very expensive and should an imported model be damaged, it has to be returned overseas to be repaired. As an illustration of this technology it was decided to perform research in water technology and then develope a handheld Infrared CO2 gas detector based prototype which would: highlight the benefits of using handheld IR CO2 gas detectors; be built locally; be powered by a 12 Volt supply; be very easy to maintain; and be cost effective. Experimental results on the accuracy and stability of the instrument formed part of this study. The IR CO2 Gas detector that was developed was used throughout the project as a prototype and testing vehicle for numerous designs. It proved to be superior to the current imported commercial instruments in terms of size, cost effectiveness and user friendliness. A further advantage of the instrument is its robustness.

- Description: This dissertation explores discourses about culture and illness in the talk of mental health professionals and indigenous healers. It represents an attempt to situate the issue of indigenous healing in South Africa within a particular strand of critical discourse analytic research. In the context of current deliberations on the value, or otherwise, of indigenous healing in a changing health and specifically mental health system, the talk of both mental health practitioners and indigenous healers as they conceptualise “disorder”, and discuss possibilities for collaboration, is chosen as a specific focus for this study. Disputes over what constitutes “disorder” both within mental health, and between mental health and indigenous healing are an important site in which the negotiation of power relations between mental health professionals and indigenous healers is played out. The results of this study suggest that despite the construction of cogent commendations for the inclusion of indigenous healing in mental health, it remains largely marginalised within talk about mental health practice. While this study reproduces to some extent the marginalisation of indigenous healing discourse, it also examines some of the discursive practices and methodological difficulties implicated in its marginalisation. However, in the context of “cultural pride strategies” associated with talk about an African Renaissance, indigenous healing may also function as a site of assertion of African power and resistance in its construction as an essentially African enterprise. At the same time, it may achieve disciplinary effects consonant with cultural pride strategies, in constructing afflictions in terms of neglect of, or disloyalty to cultural tradition. These results are discussed in terms of the methodological difficulties associated with interviewing and discourse analysis of translated texts, which contributes to difficulties with articulating indigenous healing discourse in a way that challenges the dominant psychiatric discourses implicated in its marginalisation within mental health. It concludes with recommendations for future research which addresses indigenous healing discourse in its own terms, and examines its operation as a disciplinary apparatus in South African society.

Hidden presences in the spirituality of the amaXhosa of the Eastern Cape and the impact of Christianity on them

- Description: This thesis is an attempt to reopen the debate on the whole question of inculturation in Southern Africa especially in light of the fact that we are now in a multi-lingual and multi-religious state. It is an attempt to rehighlight the plight of the spirituality of the amaXhosa people over the last century when missionary and imperial onslaught relegated it to the doldrums. This plunged the amaXhosa in a crisis that has left them directionless, to put it mildly. This is said because the total onslaught destroyed their self-respect and their identity and begs the question as to whether their acceptability to God was contingent on renouncing their culture especially the hidden presences - Qamata, the living-dead and the notion of evil spirits. It is precisely because of these misconceptions regarding African culture and spirituality that the thesis has a strong expository and apologetic bias primarily aimed to address, and put into proper perspective, the significance of the Supreme Being, the living-dead and the evil spirits in African culture. The issues are discussed within the broader socio-historical context. The thesis is basically comparative in that it uses Celtic spirituality and the approach of the early Celtic church to the question of inculturation as its point of departure and as a foil against which the preposterous actions of the church in Africa should be seen. This comparative element is also reflected in the unmistakable `dichotomy’ of Western religion and African spirituality, or better still, lack of spirituality, that was so fervently maintained by the missionaries and the colonialists alike. It is for this reason that I concur with Chidester (1996:xiv) that `the study of religion must find itself, once again, on the frontier’. The study is informed by this approach right through. It should be stressed, from the outset, that the idea is not comparison in order to satisfy our curiosity, nor is it comparison in order to try to authenticate and vindicate the beleaguered African culture. The central idea of the study is to expose the absurdity of the policies of the past century in this regard. The myth of the pure blooded Christianity is confronted, if not exploded. Several examples of both inculturation and continuities between Christianity and other faiths such as the Jewish founding faith are given. The subtheme of cultural domination subtly spans the whole study culminating in Chapter Four where the blacks begin to appropriate some of the Christian symbols and the whites also begin to assimilate African concepts such as ubuntu.

- Description: Histological examination of gametogenesis revealed that the current staging criteria used to assess gonadal recrudescence of the redeye labeo, Labeo cylindricus, were adequate. Gametogenesis was qualitatively similar to that of freshwater teleosts with a clearly defined seasonal reproductive cycle. L. cylindricus undergoes seasonal gross morphological and cytological gonadal changes with previtellogenesis dominating during the winter, vitellogenic development during spring and summer culminating in large-scale spawning at the end of summer. Post-spawning mass atresia of oocytes was evident in autumn. The histological data presented support macroscopical evidence that L. cylindricus is a synchronous iteroparous spawner, reproducing over a short period each year throughout its life-span.

- Description: The research problem addressed in this study was to identify what management skills do middle managers require to manage the organisational units effectively. To achieve this objective a theoretical model of management skills required by middle managers to effectively manage a public hospital was developed, using relevant literature in which management skills are identified. The theoretical model consisted of the following categories of management skills whose correct application can promote managerial effectiveness in managing organisational units: General management skills; Technical skills; Human skills; Leadership skills; Financial management skills; Computer skills. Each category of the management skills was broken down into elements that were then analysed using literature identified during the literature study. The model was then used to develop a questionnaire to assess the degree to which managers responsible for running the clinical, nursing and paramedical departments of a public hospital in the Eastern Cape rate the elements in terms of importance. The empirical results obtained indicate that a wide variety of skills are regarded by middle managers as important to performance of their managerial roles. This resulted in the theoretical model being confirmed and the identified management skills being accepted as management skills required by middle managers to effectively manage a public hospital in the Eastern Cape.

- Description: Although fire is recognised as an important determinant of the structure and function of South African savannas, there are few studies of long-term impacts. Controlled burning blocks of contrasting fire season and frequency have been maintained throughout the Kruger National Park for almost 50 years. This paper reports on a quantitative study of the Satara plots to determine the long-term impacts of fire frequency on woody community structure and soil nutrients. Increasing fire frequency significantly decreased woody plant basal area, biomass, density, height, and mean stem circumference. The number of stems per plant and the proportion of regenerative stems increased with increasing fire frequency. Effects on species richness of woody plants were inconsistent. There were no significant differences attributable to fire frequency for any of the soil variables except organic matter and magnesium. Organic carbon was highest in the fire exclusion treatment and lowest in soils from plots burnt triennially. Magnesium levels were greatest in the annually burnt soils and least in the triennial plots.
