- Description: Spectroscopic changes observed on addition of nitrite to solutions of cobalt(II) tetra-sulfophthalocyanine ([Co(II)TSPc]4-) in the presence of N− 3 or ClO− 4 are reported. There is spectroscopic evidence for the oxidation of [Co(II)TSPc]4- to a [Co(III)TSPc]3- species in the presence of nitrite ions. Equilibrium and kinetic studies for the interaction between [Co(II)TSPc]4- and NO− 2 are reported. The rate was found to be first order in both [Co(II)TSPc]4- and NO− 2. The rate constant for the forward reaction, k f=1.6 × 10−4 dm3mol−1s−1 was determined at 20°C for the interaction between nitrite ions and [Co(II)TSPc]4- in the presence of NO3 − or ClO4 − ions.

- Description: The purpose of this thesis is to investigate the influences of a military nature affecting the life of Ignatius of Loyola up to the time he wrote The Spiritual Exercises, and to assess whether such influences may have affected the theology and form of The Spiritual Exercises. The investigation opens with an apologetic on why the author considers it desirable to examine The Spiritual Exercises from this point of view. Thereafter a review of the life of Ignatius up to the time he wrote The Exercises is undertaken to identify which sources may have provided influences of a military nature or nuance, and to examine what possible effect these had upon Ignatius. The potential sources of influence examined include Ignatius's family background and the milieu in which he grew up, the attitude of his mentors in particular and society in general to the profession of arms, and Ignatius's own response to this attitude. From the age of twenty-five to thirty Ignatius was employed on duties of a principally military nature until he was severely wounded at the Battle of Pamplona in 1521. Therefore his military experience is examined together with an attempt to assess the degree, if any, of his spirituality at that point in his life. This is followed by an investigation of the literary sources available to Ignatius from the time of his wounding up to the time when he wrote The Spiritual Exercises at Manresa. Thereafter an examination of the changes which took place in his psyche and spirit, from the time he was wounded up to the time he wrote The Spiritual Exercises is undertaken, in order to ascertain whether his attitude to military concepts immediately prior to writing The Exercises had changed from his pre-Pamplona days. The Spiritual Exercises are then examined to consider which portions, if any, were affected in form or theology by military influences or nuances. The conclusion reached is that whereas The Spiritual Exercises are in no way a military treatise, the form is affected to a reasonable degree by Ignatius's experiences of, and attitude to, the military life, whereas the theology is affected only slightly.

With the accelerated process of political and socio-economic transformation in South Africa, revolutionary organisational change has become a given in contemporary South African business life (Human & Horwitz, 1992). For revolutionary organisational change to succeed in South Africa, middle managers who represent the 'cement' of the organisation, need to adjust at the individual level. However, the literature on organisational change remains curiously silent about individual adjustment (Ashford, 1988). The goals of the research were firstly, to recount the middle manager's perceptions and experiences of revolutionary organisational change. Secondly, to detail the psychological re-

- Description: In this research the relationship between people and the space they occupy will be looked at. In doing so, we shall see how people enter into a relationship with their environment in order to create out of material at their disposal, a shelter wherein they can live. By erecting a structure which serves as a house, the people involved in this project do essentially the same as other people in other parts of the world, who create a dwelling that provides protection against the climate and the elements in nature. A question to be raised, is extent their (i.e. the people involved in this project) entering into a relationship with their environment, was forced into a particular direction because of a set of political and economic factors. What are the political and economic factors which impact on the manner of building houses in the informal residential areas of Grahamstown? Traditional housing in France, for example, differs from region to region and has been shaped over long periods of time by the climate, family structures, the availability of land, modes of production, etc. One finds that large vine-growing families from the Mediterranean South of France live in fairly big villages; individual farmers of Brittany dwell in small, slate-roofed houses which are isolated among enclosed fields; pastoral communities in the Alps undertake seasonal moves up or down the slopes of the mountains and share their space during winter with their cattle. The way in which these families and/or communities have come to shape their lifeworlds, was not exposed to the same kind of determining factors as, for instance, in South Africa in general and in Grahamstown in particular. Notwithstanding political and economic determinants, it is clear that residents of informal houses in the Grahamstown area draw to a large extent from tradition with regards to the kind of shelters which they build (cf. the many mud-and-stick constructions). Similarly the settlement of people impacts on nature. Elements of the environment inform certain choices, but people interpret their natural environment and will erect shelters in terms of these interpretations. In addition there are the issues of how people orientate themselves in terms of important landmarks, what kind of representation they have of the future they are moving towards and which values do they draw from or attribute to their physical environment. The landscape surrounding people, contains and reflects cultural information. Important landmarks express aspects of life: the past, the present and the future. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

- Description: This workshop is designed to give you a reliable introduction the Employment Equity Act. It is based on hard information and on ACTIVITIES or discussion exercises that will help you to understand how the Act works, who it covers, and what the implications are for trade unionists. Each of the Activities is complemented with information that will help you to understand the Act in more detail. Sections have been added to help you find further information, and to understand the terms that are used in the Act itself In a two day programme, you are not going to be an 'expert' on the Employment Equity Act, but we hope that you will feel more confident about using the Act, especially in ensuring that it is used to address a wide range of discriminatory practices at the workplace. As with most legislation, the more that you begin to use it, the more its strengths and weaknesses will emerge. It is very important that any weaknesses in the practical application of the Act are reported through your Union to the Federation. This will help the Federation to campaign for improvements in the legislation, and to close any loopholes that allow employers to avoid their responsibilities. All Labour Legislation, including the new Employment Equity Act should serve as a 'base-line' or minimum standard. Employer and Union observance of the minimum standards as laid down in law should be our starting point. Through collective bargaining and improved Union organisation, we aim to improve upon the standards set by the law, and increase the protection of our members. This is a real challenge. It is especially important for us all to recognise that as we enter into a period where employers are demanding more 'flexibility', the introduction of a new law to correct the legacy of imbalances left by apartheid at the workplace deserves our special attention. We hope this workshop is the first in a series of educational events that will cover this vital new area. The main aim of this workshop is to help you to understand the basic workings of the law, and how best it can be implemented. We also hope this programme encourages you to find out more about Employment Equity issues, and contribute positively to the struggle for the eradication of inequality. This pack is designed for a series of two-day introductory workshops that are being sponsored by COSATU in each region. A workshop of COSATU Educators held in September 1999 helped to assemble the material, and to test its appropriateness. As a result there are a considerable number of educators who can advise, and facilitate this workshop and who can be contacted via COSATU Education Department. We would also be very interested to hear how the pack has been used, and in particular how it can be improved to meet the needs of trade unionists who want to tackle discrimination using the tool of the Employment Equity Act, as well as other organisational means. If you use this pack, feedback would be most welcome.

- Description: The primary aim of this study was to investigate the population dynamics of the fishes associated with a small (17.5 hectares) temporarily open/closed estuary on the south east coast of South Africa. The results are based on the findings of an intensive sampling programme conducted over a period of four years in the East Kleinemonde estuary (33° 32' S : 27° 03' E). By adopting a quantitative approach, this study addresses the need for information on estuarine-associated fish population sizes, standing stock (biomass) estimates and productivity. The ichthyoplankton assemblage in the surf zone adjacent to the mouth of the estuary was dominated by postflexion larvae representing at least 21 taxa in 14 families. Rhabdosargus holubi of sizes ranging between 9 mm and 21 mm BL was the most abundant species with a mean density of 7.3 individuals per 100 m'. This species, which accounted for 77.6% of the catch composition, was recorded throughout the year but revealed a distinct peak in abundance in spring (August - September). The ichthyofaunal community within the East Kleinemonde estuary was dominated by juvenile marine-spawning species and typical of a warm temperate southern African estuary. A total of 30 species in 17 families was recorded, including the endangered estuarine pipefish Syngnathus watermeyeri. Multivariate analyses (classification and ordination) of the catch assemblages revealed a high degree of similarity (> 70%) throughout the estuary, with two distinct groups being identified on the basis of substratum type. The sampling stations near the mouth with a sandy substratum were distinguished from all other sampling sites in the estuary. The dominant estuarine-spawning species were represented by all life-history stages, suggesting that they bred successfully in the estuary. This group was numerically and gravimetrically dominated by the two zooplanktivorous shoaling species Gilchristella aestuaria and Atherina breviceps with density extrapolated population size estimates of 420 973 and 198 275 individuals, and biomass estimates of 1.6 and 0.6 g m⁻² respectively. The total population size of all estuarine-spawning species with a mean biomass 00.4 g m⁻² was estimated at 754 217 individuals. Population size estimates of the marine-spawning species were calculated using data obtained from three independent mark-recapture experiments. The assumptions for the mark-recapture analyses were adequately met and it was concluded that the techniques provided reliable estimates of population size. However, estimates obtained from density extrapolation revealed enormous variability and were considered to be unreliable. The total population size was estimated at 63 342, 18 592 and 13 5 192 during the three mark-recapture experiments respectively. The numerically dominant species during all three experiments was Rhabdosargus holubi. Biomass production of the marine-spawning species was evaluated over a 123 day census period when population sizes and estimates of growth rates were known. Productivity for all fishes with a standing stock of 26.2 g m⁻² was calculated at 4.5 g m⁻² month01 Rhabdosargus holubi accounted for more than 75% of the total marine fish productivity. This study draws attention to the success of Rhabdosargus holubi in the East Kleinemonde estuary, which is ascribed to aspects of its biology. These include an extended breeding season, the ability to recruit into the estuary under adverse open mouth conditions and its omnivorous food habits. The dominance of this migratory species suggests that it plays an important role in the transfer of energy to the coastal marine environment when the mouth of the East Kleinemonde estuary opens. Predation by birds and a dominant piscivorous fish (Lichia amia) was quantitatively assessed over a period of two years. Monthly food consumption by all piscivorous birds revealed large temporal variability, ranging from 32 to 466 kg month-I An unusual invasion of Cape cormorants during the winter of 1994 accounted for large scale mortality (2246 kg of fish) over a relatively short period. The predatory impact of this episodic event was reflected in the findings of the fish mark-recapture experiments, which revealed a 70% reduction in the total population of marine-spawning fishes (above a certain minimum size) in the estuary subsequent to this invasion. Monthly food consumption by the Lichia amia population in the estuary was calculated at 68 and 58 kg month-I for two distinct time periods when the population size was known. These findings suggest that this species is the top piscivorous predator in the East Kleinemonde estuary. Finally, the findings of this study highlight the temporal variability of fish populations within a single estuary. It is suggested that predation and estuary mouth conditions are the main factors influencing the abundance (and its variability) of individual species in the East Kleinemonde estuary.

- Description: To fully comprehend the complex process of news making, we must first understand that the events we read about everyday in the newspaper are not merely a reflection of the world in which we live. News does not just happen. Rather, it is a socially constructed product in which events are “made to mean” (Hall, 1978). Thus, the news plays a fundamental role in shaping our interpretations of reality - our perceptions of the world as we know it. Informed by a structuralist approach to news making, this research provides a detailed ethnographic study of the determinants that shape and produce news in the South African print media. I provide examples of the influence various factors, operating at all levels, exert within the news making process. The research focuses on the news production process at East Cape News Pty. Ltd. (ECN) a small news agency operating in the peripheral news region of South Africa’s Eastern Cape. It considers the journalistic routines and interests of the ECN reporters; how these reporters select events and turn them into news, how they interpret their significance and how they formulate them as news stories. The research also considers the second stage of selection ECN news must pass before it is read by the public - the “gates” of external newspapers. In this section, the study is primarily concerned with which ECN news stories succeed past the gates of national newspapers as these are the newpapers that play an influential role in shaping national perceptions of the marginalised Eastern Cape region. A province burdened with devastating rural poverty, unstable government, and little economic growth, the Eastern Cape warrants little coverage from the national, Johannesburg-based news market. As a result, little news of the Eastern Cape is published nationally, further perpetuating the region’s perceived insignificance on a national level. This point also demonstrates the fact that news both shapes, and is shaped by, our ideologies. News, therefore is ideological (Fishman, 1977). My findings reinforce many of the observations of other media researchers informed by a structuralist approach in the field of news making. However, some elements of news making emerge which appear to be unique in terms of other studies of news making. These elements are primarily a result of ECN’s informal organisational structures which allow the journalists a greater level of autonomy than a larger more bureaucratic organisation might. Thus, in addition to considering the structures that shape the news, I also discuss the role of human agency in making the news.

- Description: Black South African English is generally regarded as the variety of English commonly used by mother-tongue speakers of South Africa's indigenous African languages in areas where English is not the language of the majority. This paper explores some of the problems involved in defining this variety, problems such as whether it is a `new' variety of English or a dialect, and problems relating to whose English it is: the English of those learners who have encountered only a smattering of English in informal contexts or the variety of English acquired during formal schooling. The second half of the paper focuses on the possible future of Black South African English (BSAE) against the backdrop of South Africa's new multilingual policy. Reasons for the continued appeal of English are examined, alongside the range of factors influencing the possible future growth of BSAE as a distinct variety. It is argued that South Africans are unlikely ever to be free not to learn English, owing to the huge economic, political and ideological constraints which make the `choice' of English inevitable. The success of current efforts to resist value judgements and recognise the worth of BSAE will depend not only on the goodwill of South Africans, and on the cooperation of all speakers of English, world-wide, but on the rate at which the variety drifts away from recognised standard forms of English.

- Description: The effects of repeated mild concussive head injury on professional rugby players were examined. Data were collected for rugby players (n=26) and cricket player controls (n=21) using a comprehensive neuropsychological test battery comprising five modalities (Verbal Memory, Visual Memory, Verbal Fluency, Visuoperceptual Tracking and Hand Motor Dexterity) and a self-report Postconcussive Symptomology Questionnaire. Group statistical comparisons of the percentage of individuals with deficit were carried out for (i) rugby versus cricket; (ii) rugby forwards versus rugby backs; and (iii) rugby forwards versus cricket. Rugby players performed significantly poorer than controls on SA W AIS Digit Symbol Substitution subtest and on the Trail Making Test. On Digits Forward and Digit Symbol Incidental Recall, the results approached significance with the rugby players showing a tendency toward impairment on these tests. Rugby players exhibited impairment in areas of visuoperceptual tracking, speed of information processing and attention, and there are tendencies of impairment in verbal and/or visual memory. Results obtained on the self-report questionnaire strongly reinforced cognitive test results and a significant proportion of rugby players reported difficulties with sustained attention, memory and lowered frustration tolerance as well as symptoms of anxiety and depression. It was consistently noted that players in the more full contact positions (rugby forwards) were most susceptible to impairment, confirming that these players, who are exposed to repeated mild head injuries, are at greater risk of exhibiting postconcussive sequelae.

- Description: This thesis is grounded in the theoretical discourses of art therapy and transpersonal psychology. The focus is on a single session of claywork, where a sculpture was made and discussed, leading to an understanding of some of the sculptor's central psychological issues. The overall aim of the research was to examine different hermeneutic perspectives on art therapy with clay sculpture in terms of how well they open up and do justice to the experience of the sculptor and the nature of the overall process. Within this there are two particular goals: Firstly, to examine the extent to which the holographic paradigm in comparison to other perspectives, allows a deeper access to, and deeper understanding of, transpersonal themes and processes; and secondly, to examine the extent to which processes within claywork can be understood as ritual activities. The research was a phenomenological-hermeneutic case study. The session was reduced to a narrative synopsis, and then a hermeneutically grounded thematic analysis was carried out using the theory of Transpersonal Feminism (Knight, 1997) and Schema-Focused Cognitive Therapy (young, 1990, 1994). The principal conclusions reached were that the holographic paradigm does add to our understanding of the experiences (personal and transpersonal) of the claywork, often beyond the scope of other art therapy perspectives. The image of the shaman is used as a metaphor for understanding the process of healing described within the holographic paradigm. Within the healing process, ritual plays an important role in the meaningful therapeutic activity of art therapy. The claywork expresses that the transpersonal struggle with archetypal forces within the collective unconscious is reflected on a personal level through individual conflicts and dilemmas within the personal unconscious. Indeed, these difficulties are viewed on both levels as 'stepping stones' on the path of spiritual development described by Engler (1984) and Welwood (1986).

- Description: Using Schein's (1992) notion of organisational culture, this study explored the position of a South African nongovernmental organisation (NGO) in the changing environment of post-apartheid South Africa. The study pursued three central goals: to describe the organisational culture of a South African NGO; to examine the tensions that have emerged owing to the changing nature of the organisational culture; and to analyze the organisational culture in relation to the changing NGO environment. The basic assumptions of the organisation regarding networking, the relationship with the government, funders and funding, leadership, human resource development, and service delivery, were collected. A single case study design was employed, with a sample of eight participants (representing the four different sections of the NGO) being drawn. Data were collected through documentary analysis, a focus group, and eight individual interviews using the critical incident technique. Analysis was performed using various qualitative data analysis techniques. The researcher found that participants considered networking, a cooperative relationship with the government, a proactive approach to obtaining funding, effective leadership and human resource development, and a good reputation for service delivery, to be essential for NGO survival. NGO basic assumptions are undergoing a transformation process, and tensions exist between long-standing and emerging assumptions. It was found that the transformation of assumptions is enabling the NGO to adapt to the challenges of the changing environment.

- Description: Part One of the research seeks to establish a context wherein certain assumptions pertaining to the interpretative dimensions of understanding the image in art therapy can be considered and reviewed. Notions about the image, meaning and reality are discussed both in terms of how they relate to current art therapy practice, and how they may be alternatively thought about, both from the perspective of ancient Hellenic Greek thought, and more contemporary thought, particularly that of phenomenological and philosophical-hermeneutics. Part Two of the research investigates the phenomenon of understanding the image in an art therapy situation, with a view to reconsidering certain of the assumptions raised in the first part of the thesis (phrased in the form of research questions). It did this utilizing a qualitative method, by exposing four respondents (patients), and two therapists to an art therapy situation in which images were created out of clay. The respondents (patients) and therapists articulated their understanding of the image production procedure, and the meaning of the images created. The way understanding occurred in the empirical part of the research was explained and illustrated by means of the hermeneutic circle, which was operational on a number of different levels. The results of the research suggest that the meaning of the image in art therapy is a creative synthesis, which emerges from within a dialectics of exchange. This exchange involves a number of meaning-generating contexts, of which the patient’s experience, and the therapist’s knowledge, form only a part. The outcome of this exchange is the derived meaning of the image, which represents a ‘fictional’ world that gives the patient and therapist a way of understanding the patient’s situation. The process of the research, which investigates the way understanding of the image in art therapy occurs, is at the same time, an application of the principles of understanding

- Description: This research explores the potential for engaging teachers in school-based environmental education curriculum development processes by using camera. The research, through its epistemological and ontological position, is closely linked to educational orientations associated with aspects of outcomes-based educational transformation in South Africa. A participatory approach that recognises teachers as co-researchers, each bringing to the inquiry her or his questions and constructions of meaning, was adopted. Participatory inquiry was initiated by setting up cluster meetings that allowed for teacher inputs through open dialogic processes. Fundamental to the inquiry is the notion that context shapes curriculum and curriculum development processes. It was from this orientation that a group of 13 teachers, using cameras to create visual narratives, explored their own diverse and complex contexts. These narratives (or stories) form the basis for further inquiry and development of sophistication with respect to the concept of environment. The research process is critically and reflexively documented as a series of field and research texts constructed from a variety of data sources gathered over the period of one year. The work is presented as a process of engaging critically with environmental education curriculum development and an opportunity to raise questions, rather than seek answers in this regard.

- Description: The primary aim of this thesis is to explore, through organisation development (OD) consultants' accounts, the meaning of 'capacity building' in the South African development context. The need for theory development in this area is apparent from two interrelated vantage points. Firstly, while 'capacity building' is an increasingly espoused development approach, it is seen to be a confusing and ill-defined concept, for which there exists no adequate theory. Secondly, there is an growing call within the OD field to perfonn 'recOIlllaissance' (Weick,1990) on OD as it is being practised in different socio-historical and organisational contexts, so as to discern future trends for this discipline. Due to the lack of documented debate which grounds OD issues in the South African development sector, OD practitioners' 'capacity building' interventions were seen to provide suitably unchartered terrain for this study. Given that theory generation was intended, the general epistemological principles provided by Glaser and Strauss's (1967) 'grounded theory' methodology were adopted. As a way of avoiding some of the criticisms and limitations of this approach, this thesis followed later conceptualisations of this method, in particular its reframing within the social constructionist idiom. In accordance with this perspective, this study directed attention to the ways in which OD consultants, in a non-governmental organisational (NGO) sector known as 'intermediary' NGOs, accounted for their 'capacity building' role in this development context. The results, based on in-depth interviews with ten OD consultants, indicate that 'capacity building' is an elusive and inchoate concept with more than one meaning for the participants. Their narrative account variously constructs 'capacity building' as value-driven OD process facilitation; funder and market regulated service provision; and people-driven product delivery. As a result of this multi-vocal construction, the participants' accounts reveal that OD consultancy in this sector is primarily concerned with 'managing the tensions' of the consultants' ambiguous and contradictory roles. By examining how the tensions articulated by the consultants inhere in their relationship to the environment in which they operate, this thesis firstly explores how the contradiction and anlbiguity attached to this concept can be traced to different stakeholder expectations of 'capacity building'. Secondly, it exanlines how these different stakeholder discourses conflict with each other and with an OD perspective. Thirdly, through an explication of the core category of 'managing tensions', it explores the image of OD consulting as a 'shifting and inconstant balancing act'. Fourthly, it shows how there exist wider contextual forces operating in the development sector which serve to throw these consultants 'off balance' and into delimited and 'received' service provision roles which run counter to their raison d'etre. Finally, the research examines new ways of approaching the 'capacity building' question and of understanding the nature of OD consultancy. It concludes with an attempt to respond to a conceptual aporia in OD literature by examining possible alternative images and metaphors for the role of the OD consultant.

- Description: This thesis investigates the design and implementation of an object-oriented toolkit for music notation. It considers whether object-oriented technology provides features that are desirable for representing music notation. The ability to sympathetically represent the conventions of music notation provides software tools that are flexible to use, and easily extended to represent less common features of music notation. The design and implementation of an object-oriented class hierarchy that captures the structural and semantic relationships of music notation symbols is described. Functions that search for symbols, and update symbol positions are also implemented. Traditional context-sensitive and spatial relationships between music symbols may be maintained, or extended to provide notational features found in modern music. MIDI functionality includes the ability to play music notation and to allow step-recording of MIDI events. The toolkit has been designed to simplify the creation of applications that make use of music notation; example applications are created to demonstrate its capabilities. , Microsoft Word , Adobe Acrobat 9.46 Paper Capture Plug-in

- Description: The phrase “glimpsing the balance between earth and sky” in the thesis title is taken from Jeanette Winterson’s Oranges Are Not the Only Fruit. In this novel, the central character Jeanette believes she has glimpsed the possibility that human relationships can find their mirror in the relationship with God, as she understands the divine Other. This glimpse has set her wandering, trying to find such a balance. This examination of four selected novels by Jeanette Winterson and John Irving shows that for Irving, “glimpsing the balance” means in part, giving voice to a strongly “Christian” view of humankind and human nature but in an age where the prevailing intellectual worldview is strongly sceptical of any Grand Narrative. The “voice” expressed in Irving’s work has to be situated, like Winterson’s, as one among many possibilities. Irving’s voice is itself masked as different, other/Other, freakish, in the narrative worlds he creates. Through his use of grotesque comedy as a vehicle for deeper philosophical concerns, Irving asks us: What after all in the postmodern world is the main show? This thesis argues that if Winterson and Irving are testing or re-presenting a Christian worldview in a postmodern context, than they are asking whether Christianity is capable of assimilating and rising above the worst circumstances the world, writer, and life can throw at it. In Oranges Are Not the Only Fruit, Winterson tells a story of “forbidden love”, posed as a direct challenge to the prevailing way of knowing in her character’s community. In Gut Symmetries, she expands this challenge by employing the insights of quantum physics to make sense of the complexities raised by a triangular love relationship. Irving offers the story of Owen in A Prayer for Owen Meany as the kind of story which might possibly make a believer out of him; in short, that he would have to be a witness to some kind of miracle, something utterly inexplicable. In A Son of the Circus Irving narrates the quest for identity undertaken by an Indian doctor who is in every way a Displaced Person – the condition, he implies, of anyone who purports to find their piece of the truth. The theoretical concerns of the postmodern project are examined through Lawrence Cahoone’s argument that postmodern writing offers criticism of: presence, origin, unity and transcendence through an analytical strategy of constitutive otherness. In each of their texts, Irving and Winterson are seen to use these four critical elements and to offer a postmodern strategy of re-presenting meaning through “constitutive otherness”. Both writers also employ a strategy of historiographic metafiction (as defined by Linda Hutcheon) as a means of constructing and re-presenting their narrated stories. Postmodern paradox is compatible with what could be called a Christian plan for living, if the latter is in turn given an appropriate 1990s interpretation. The selected novels by Winterson and Irving are offered as contemporary evidence for this view. This thesis argues that the connection between postmodernism and other worldviews, particularly Christianity, is found in both projects’ process of making meanings through encounters with an other/Other.

- Description: Waste-generating industrialisation is intrinsically associated with population and economic proliferation. This places considerable emphasis on South Africa's water shortage due to the integral relationship between population growth rate and infrastructure development. Of the various types of industry-generated effluents, those containing organic pollutants such as phenols are generally difficult to remediate. Much work has been reported in the literature on the use of enzymes for the removal of phenols from these waste-streams but little application of this bioremediation approach has reached practical fruition. This study focuses on integrating and synergistically combining the advantages of enzyme-mediated dephenolisation of synthetic and industrial effluent with that of membrane teclmology. The ability of the enzyme polyphenol oxidase to convert phenol and a number of its derivatives to chemically reactive o-quinones has been reported extensively in the literature. These o-quinones can then physically be removed from solution using various precipitation or adsorption techniques. The enzyme is, however, plagued by a product-induced phenomenon known as suicide inactivation, which renders it inactive and thus limits its application as a bioremediation tool. Integrating membrane technology with the enzyme's catalytic ability by immobilising polyphenol oxidase onto polysulphone and poly(ether sulphone) capillary membranes enabled the physical removal of these inhibitory products from the micro-environment of the immobilised enzyme which therefore increased the phenol conversion capability of the immobilised biocatalyst. Under non-immobilised conditions it was found that when exposed to a mixture of various phenols the substrate preference of the enzyme is a function of the R-group. Under immobilised conditions, however, the substrate preference of the enzyme becomes a function of certain transport constraints imposed by the capillary membrane itself. Furthermore, by integrating a quinone-removal process in the enzyme-immobilised bioreactor configuration, a 21-fold increase in the amount of substrate converted per Unit enzyme was observed when compared to the conversion capacity of the inunobilised enzyme without the product removal step. Comparisons were also made using different membrane bioreactor configurations (orientating the capillaries transverse as opposed to parallel to the module axis) and different immobilisation matrices (poly(ether sulphone) and polysulphone capillary membranes). Conversion efficiencies as high as 77% were maintained for several hours using the combination of transverse-flow modules and novel polysulphone capillary membranes. It was therefore concluded that immobilisation of polyphenol oxidase on capillary membranes does indeed show considerable potential for future development.

Dreamwork and imaginal healing: the incorporation of artwork in a systematized method of group dreamwork

- Description: This exploratory study investigated the expansion of an established systematized group dreamwork method (Shuttleworth-Jordan, 1995) to incorporate artwork. The rationale for the addition of artwork was situated firstly, in a poetic Jungian understanding of the image as a holistic "place" of gnosis or transformative healing and, secondly, in an argument that in order to carry the gnostic potential of the image into the lived world, a dreamwork method should involve all four styles of consciousness (thinking, intuition, sensation and feeling). It was considered that the verbal interpretive Shuttleworth-Jordan method would be enhanced by the incorporation of a visual artwork process in order more fully to open the potential of the method for incorporating the nonverbal intuitive, sensation and feeling styles of consciousness. In order to compare the established method (dreamwork Without Art) and the proposed method (dreamwork With Art), two dreamwork workshops were conducted in which all participants experienced all four conditions of the study: Dream Presenter Without Art, Dream Presenter With Art, Group Member Without Art, Group Member With Art. Two levels of assessment were utilized: a quantitative analysis (involving rating scales completed after each dreamwork session), supported by a qualitative analysis (involving written questionnaires completed at the end of the workshops and follow-up interviews conducted a week after completion of the workshops). The results suggested that the incorporation of artwork in the Shuttleworth-Jordan (1995) group dreamwork method enhanced the established method in that a consistent trend of increased involvement in the dreamwork process and increased dreamwork effectiveness was reflected, while no deleterious effects were noted which might detract from the effectiveness of the existing model which had been established in previous research studies. Finally, a refined step-by-step group dreamwork method incorporating artwork was proposed, which included qualitative feedback from the present study.

- Description: During this study, an attempt was made to explore the opinions and attitudes of members of the South African Police Service (SAPS) towards issues of diversity before, immediately after and three months after participating in diversity training workshops presented by the SAPS Training Division during 1997 in Port Elizabeth. The aim of this thesis was not to assess the diversity training itself, but to discover if the training, as currently presented, in any way influenced the attitudes of participants. In order to meet this goal, literature and empirical studies were conducted. The literature study sets the theoretical foundation pertaining to the history of the SAPS and the attitudes and prejudices of and diversity among SAPS members. During the empirical research phase, a non-probability purposive sampling procedure was adopted. Four of a range of diversity workshops presented by the Training Division of the SAPS during 1997 were selected for the purpose of this study. An internal SAPS process was used to nominate members to attend the workshops. The researcher requested the participants in each of the four workshops to complete a self-administered questionnaire before as well as after the workshop concerned. Immediately after each of the four workshops, a short interview was held with each attendee. To explore the stability of any change evident from responses on the questionnaires completed after the workshops, the attendees were again requested to complete the same questionnaire three months later. To increase the validity of any conclusion that attitudinal change was related to the workshop, a control group was used. This study has revealed that a cross-spectrum of SAPS members of both sexes and diverse racial backgrounds believe that various forms of discrimination exist within the SAPS. It confirmed that the diversity training presented by the SAPS Training Division is a useful instrument to heighten members' awareness of the different norms and customs of other cultural/ethnic groups and of the necessity that the SAPS should be constituted of a cross-spectrum of racial groups reflecting the South African society. Finally, based on the research findings, recommendations were made involving management and its supportive services and diversity training.
