- Description: The international banking environment has become potentially riskier because of the recent developments in financial services and products which have changed the way banks do their day to day business. Imposing minimum capital adequacy regulations is one way of fostering stability in the global banking system. A number of countries have started to implement the new capital adequacy rules (Basel II) following the worldwide consensus among central bankers that bank‟s capital levels should be regulated to enhance global financial stability. In this study, through the comparative analysis of the general implementation issues it was established that emerging countries apply all Basel II rules uniformly across all the banking institutions that operate in their territories. Developed countries apply these rules only to large and internationally active banks and because of the diversity of their banking industries, they also apply domestically modified rules to the domestically based banks. For the successful implementation of Basel II, properly planning, devoting bank resources and making necessary legislative amendments are prerequisites for incorporating Basel II into the regulatory framework for any country. The study concludes that the current global financial turmoil continues to pose a threat to the effectiveness of the Basel II rules which are aimed at achieving global financial stability.

- Description: Cellular telephones have revolutionised the art of communication across all societies, and South Africa is no exception. Access to this form of communication has made personal contact easier, in both rural and urban contexts. Globally this form of communication has been readily embraced. However, cultural rules that pertain to face-to-face communication are often flouted by cellular phone users. This flouting holds true no doubt across many cultures, languages and contexts. Bloomer (2005:97-100) assesses this flouting of cultural maxims in relation to Grice's cooperative principle. This article attempts to assess how general rules of politeness in isiXhosa have been and are being transformed by what could be termed the "economics of speaking".

- Description: In many societies in developing countries, women are not given a chance to communicate their issues. The organisation within these societies places men at the top, giving them the opportunity to make all the important decisions. This situation is reflected in the two films which fall under this study, namely, Water and Moolaadé both of which are fictional representations of the oppression of women. In this study, an attempt is made to explain communication struggles in the two films: Water, reflecting Indian society and Moolaadé, reflecting African society. To understand the outcome of these struggles against patriarchy, the study looks at two types of feminism: Indian feminism and African feminism and attempts to find the sense that characters in the film can be understood. The analysis also looks at what the women, who act as feminists in the films have achieved out of their struggles to break the silence and how their voices have influenced or sensitised the silenced majority of women in their societies. Feminist communication theories have been used to analyse the female voice in the films. In the conclusion, I have argued that in both films women have managed to transform their respective societies. However more potential to social transformation are revealed by women depicted in Moolaadé than in Water, where there is very slow pace of change.

- Description: A good understanding of customer expectations is very important to service providers. Since the Chinese first came to South Africa and started their restaurant businesses. Chinese fine-dining restaurants have become more and more popular. Identifying the customer expectations and Chinese fine-dining restaurant owner perceptions will help Chinese service providers to understand better the restaurant businesses. To ensure the development of the Chinese restaurant business in South Africa, it is very important to understand what South African customers want, whether there are differences between the Chinese restaurant owner perceptions of the service quality and South African customer expectations of the service quality. This would depend on the customers’ preferences, and provide a positive contribution to customer decision-making. Therefore, it is essential to understand and identify what is customer expectations are, what the management perceptions are and the differences between them. 5 In order to achieve the objectives of the research, the following approach was followed: Factors that influence the customer expectations and management perceptions are explained. Five factors used to measure the service quality of Chinese fine-dining restaurants are identified, namely reliability, responsiveness, assurance, empathy, tangibility. The responses to the questionnaire were collected and analysed to determine the extent to which factors are both important to customer expectations and management perceptions.

- Description: A number of mostly informal areas in Nelson Mandela Bay have experienced rapid expansion over the past decade or so. Census data available for these areas is outdated and does not provide enough information for local authorities to accurately plan for tasks such as service delivery management and resource allocation. In this dissertation, a GIS based demographic and Quality of Life study of informal settlements and previously disadvantaged areas within Nelson Mandela Bay is undertaken to address this issue. The study aims to integrate GIS technology into a demographic and Quality of Life survey to significantly improve the collection, analysis, interpretation, display and management of survey data and to provide the accurate and necessary updates required between census collections. Data relating to informal settlements were captured from aerial photographs and satellite imagery and demographic and Quality of Life data were collected from field surveys. The results demonstrated that the use of GIS technology provided more accurate information for demographic variables, including the number of dwellings, dwelling type, size of the population and population dynamics. A specific demographic trend observed through spatial analysis included the identification of backyard shacks predating formal structures in settlements. The analysis and representation of the Quality of Life field survey data in GIS demonstrated how residents' perceptions of problems and issues in their neighbourhoods are better interpreted, understood and managed when analyzed within a spatial context. This research concluded that GIS based demographic and QOL studies are vital for providing accurate social and spatial information for municipalities, particularly in urban environments of developing countries, and for providing the necessary updates to censuses occurring every ten years.

- Description: Extensive areas of the Eastern Cape Province have been invaded by Pteronia incana (Blue bush), a non-palatable patchy invader shrub that is associated with soil degradation. This study sought to establish the relationship between the invasion and a range of eco-physical and land use gradients. The impact of the invader on soil moisture flux was investigated by comparing soil moisture variations under grass, bare and P. incana invaded surfaces. Field based and laboratory spectroscopy was used to validate P. incana spectral characteristics identified from multi-temporal High Resolution Imagery (HRI). A belt transect was surveyed to gain an understanding of the occurrence of the invasion across land use, isohyetic, geologic, vegetation, pedologic and altitudinal gradients. Soil moisture sensors were calibrated and installed under the respective surfaces in order to determine soil moisture trends over a period of six months. To classify the surfaces using HRI, the pixel and sub-pixel based Perpendicular Vegetation Index (PVI) and Spectral Mixture Analysis (SMA) respectively were used. There was no clear trend established between the underlying geology and P. incana invasion. Land disturbance in general was strongly associated with the invasion, as the endemic zone for the invasion mainly comprised abandoned cultivated and overgrazed land. Isohyetic gradients emerged as the major limiting factor of the invasion; a distinct zone below 619mm of mean annual rainfall was identified as the apparent boundary for the invasion. Low organic matter content identified under invaded areas was attributed to the patchy nature of the invader, leading to loss of the top soil in the bare inter-patch areas. The area covered by grass had consistently higher moisture values than P. incana and bare surfaces. The difference in post-rainfall moisture retention between grass and P. incana surfaces was significant up to about six days, after which a near parallel trend was noticed towards the ensuing rainfall episode. Whereas a higher amount of moisture was recorded on grass, the surface experienced moisture loss faster than the invaded and bare surfaces after each rainfall episode. ii There was consistency in multi-temporal Digital Number (DN) values for the surfaces investigated. The typically low P. incana reflectance in the Near Infrared band, identified from the multi-temporal HRI was validated by field and laboratory spectroscopy. The PVI showed clear spectral separability between all the land surfaces in the respective multi-temporal HRI. The consistence of the PVI with the unmixed surface image fractions from the SMA illustrates that using HRI, the effectiveness of the PVI is not impeded by the mixed pixel problem. Results of the laboratory spectroscopy that validated HRI analyses showed that P. incana’s typically low reflectance is a function of its leaf canopy, as higher proportions of leaves gave a higher reflectance. Future research directions could focus on comparisons between P. incana and typical green vegetation internal leaf structures as potential causes of spectral differences. Collection of spectra for P incana and other invader vegetation types, some of which have similar characteristics, with a view to assembling a spectral library for delineating invaded environments using imagery, is another research direction.

- Description: New drugs, particularly antibiotics, are urgently required to combat the increasing problem of antibiotic resistant human pathogens. Due to the scarcity of products available today, the pharmaceutical industry is now under pressure to reassess compounds derived from plants, soil and marine organisms. Pharmaceutical companies are showing renewed interest in marine biotechnology as the oceans represent a rich source of both biological and chemical diversity of novel molecular structures with anti-cancer, anti-inflammatory and antibiotic properties. Formerly unexplored locations, such as deep ocean sediments, show great potential as a source of genetically novel microorganisms producing structurally unique secondary metabolites. In this research, a metabolite producing marine Pseudoalteromonas strain, known as AP5, was initially used to develop methods for the detection, optimisation of production and extraction of bioactive metabolites from other potentially novel marine isolates. Two hundred and seventy six (276) marine isolates from water and sediment samples from the Antarctic Ocean and Marion Island were isolated. Ten visually different isolates were screened for bioactivity against Gram-positive and -negative bacteria, fungi and yeast. Three out of the 10 isolates, WL61 , WL 114 and WL 136, appeared to be novel Streptomyces spp. showing activity against different test organisms. Many of these marine microorganisms are difficult to culture in the laboratory, particularly when they are cultivated continuously in shake flasks as they can stop producing bioactive compounds. The cultivation of marine isolates in bioreactors may be a more beneficial process for the optimisation of metabolite production compared to conventional liquid fermentation techniques whereby the solid-liquid-air interface of membrane bioreactors can imitate the natural environment of microbes. The membrane bioreactor system is a stable growth environment with low shear that supports steady-state biofilm growth consisting of a high cell density due to a high mass transfer of nutrients and oxygen to the cells. This approach was employed and isolates WL61, WL114 and WL136 were immobilised onto ceramic membranes using Quorus single fibre bioreactors (SFR). The SFRs were used to establish the most suitable growth medium for continuous secondary metabolite production. The best growth conditions were applied to the Quorus multifibre bioreactor (MFR) for scale up of biologically active metabolites, highlighting the potential of bioreactor technology for use in bioprospecting for isolating and screening novel and known organisms for new and interesting natural products. Furthermore, the Quorus MFR was shown to be suitable for the production of high yields of antimicrobial metabolites and is an efficient new fermentation production system. Purification by HPLC fractionation was used to characterise four major compounds from isolate WL 114 extracts. NMR structure elucidation identified one of the two primary compounds as Bisphenol A. The complete chemical structure for the second potent bioactive compound could not be determined due to the low concentration and volume of material. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

Furthermore, the Quorus MFR was shown to be suitable for the production of high yields of antimicrobial metabolites and is an efficient new fermentation production system. Purification by HPLC fractionation was used to characterise four major compounds from isolate WL 114 extracts. NMR structure elucidation identified one of the two primary compounds as Bisphenol A. The complete chemical structure for the second potent bioactive compound could not be determined due to the low concentration and volume of material. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Technological shift has become significant and an area of concern in the health sector with regard to securing health information assets. Health information systems hosting personal health information expose these information assets to ever-evolving threats. This information includes aspects of an extremely sensitive nature, for example, a particular patient may have a history of drug abuse, which would be reflected in the patient’s medical record. The private nature of patient information places a higher demand on the need to ensure privacy. Ensuring that the security and privacy of health information remain intact is therefore vital in the healthcare environment. In order to protect information appropriately and effectively, good information security management practices should be followed. To this end, the International Organization for Standardization (ISO) published a code of practice for information security management, namely the ISO 27002 (2005). This standard is widely used in industry but is a generic standard aimed at all industries. Therefore it does not consider the unique security needs of a particular environment. Because of the unique nature of personal health information and its security and privacy requirements, the need to introduce a healthcare sector-specific standard for information security management was identified. The ISO 27799 was therefore published as an industry-specific variant of the ISO 27002 which is geared towards addressing security requirements in health informatics. It serves as an implementation guide for the ISO 27002 when implemented in the health sector. The publication of the ISO 27799 is considered as a positive development in the quest to improve health information security. However, the question arises whether the ISO 27799 addresses the security needs of the healthcare domain sufficiently. The extensive use of the ISO 27002 implies that many proponents of this standard (in healthcare), now have to ensure that they meet the (assumed) increased requirements of the ISO 27799. The purpose of this research is therefore to conduct a comprehensive comparison of the ISO 27002 and ISO 27799 standards to determine whether the ISO 27799 serves the specific needs of the health sector from an information security management point of view.

- Description: This study investigated the reduction reaction of ruthenium tetroxide by various aliphatic alcohols in acidic medium. UV-Vis spectroscopy still plays an essential role in the analysis and study of volatile ruthenium tetroxide and was used in this study to collect kinetic data. This data was analyzed using graphical and computational methods, such as Mauser diagrams and kinetic simulation software. From the results obtained it is proposed that the reaction occurs by the following two-step reaction model: Ru(VIII) k1 Ru(VI) Ru(VI) k2 k-2 Ru(III) Molar extinction coefficients and conditional rate constants were calculated using kinetic simulating software and a hydride transfer mechanism was proposed. The temperature dependence of this reduction reaction was also investigated and thermodynamic parameters calculated. Ruthenium concentrations were determined using a method employing UV-Vis spectroscopy. The method proved to be a reliable, sensitive and simple technique.

- Description: The key debates after apartheid have been on the successes and shortcomings of the social and economic policies that were adopted after apartheid. The ANC government decided to approach poverty reduction by closing the inequality gap between racial groups in the country. It planned to provide services that would improve the poor people’s lives and also create employment to sustain development. To provide the necessary services, the government formulated two broad, but linked macroeconomic policies namely: the RDP and GEAR which focused on the demand and supply side respectively (Venter and Landsberg (2006). This indicated the importance with which the people’s welfare and growth were regarded by the South African government. It indicated that the government believed in pro-poor growth. The purpose of this study was to gain better and deeper understanding about poverty reduction since the 1994 political transition, from the poor people of Airport Valley (in the Nelson Mandela Metropolital Municipality), who experience poverty from the real world. The study attempted to find out from these people if there was improvement in their lives since democratisation. This qualitative and quantitative study used three methods of collecting data namely: a questionnaire, interviews and observation. The results of the study suggest that there has been lack of commitment by RDP and GEAR, as the conditions under which the people live and therefore their standard of living have not improved. The study recommends that the government should speed up the process of service delivery at Airport Valley and also include the people in decision making about the future of Airport Valley.

- Description: This research study examined whether the physical resources in rural secondary schools are adequate and are managed properly by the school principals, for quality education to be achieved in the Eastern Cape Province. The dramatic changes in South Africa recognized that the future depends on an education system which develops the full potential of all learners. Although the Constitution of South Africa is advocating for equal education for all, there are disparities which are evident in the quality of the infrastructure, especially in remote rural areas where the fundamental requirements for effective education are lacking such as, water, electricity, sanitation and basic educational equipment. This shows that, although policy and legislative frameworks for transforming the education system have been put in place, managing the change is still a key challenge especially that of physical resources. Management of physical resources illustrates the problems facing principals by pointing to the lack of basic facilities in many rural secondary schools. In terms of the provision and management, many challenges remain, like most schools do not have adequate physical facilities. School buildings such as classrooms are inadequate or unsafe with no toilets, libraries, laboratories and many learners and teachers do not have learner teaching support materials (LTSMs). On the other hand, in terms of the Constitution, the Department of Education is responsible for bringing redress, equality and to upholding the Constitutional values such as shared decision-making, transparency, shared accountability and empowerment for equal partnership with other stakeholders. The physical resource management is one of the major responsibilities of principals. Their leadership is largely about ensuring that a clear and shared sense of direction is developed for both leadership and management. The school viii system meant that schools have moved nearer to the communities they serve and this has led to schools being more accountable to their communities. This study further investigated whether there is a significant correlation between the management of physical resources and quality education as well as the eradication of poverty in the rural secondary schools of the ECP. The proper execution of the management tasks of planning, organizing, leading, and controlling (POLC) by the principals have contributed extensively to the success of the schools. Therefore, this will mean that the act of managing physical resources through POLC and the process of working with or through SGBs, teachers, parents, learners, EDOs and the community at large to achieve set goals of education of relevance, excellence and quality education by effectively and efficiently using the physical resources in a school climate and environment that is collegial. The study showed that there is a link between management tasks (POLC) and collegial style of leadership in the school. The literature reviewed supported the view that the invitational style of leadership and collegiality increase the potential of a school to manage its physical resources economically, efficiently and effectively, particularly in a climate where the resource handlers take ownership of the school especially in remote rural settings. The 255 out of 300 subjects (85%) chosen to participate in this study were selected on the basis of their accessibility. Convenience sampling was used to conduct the study as this ensured that the population represented stakeholders that manage physical resources at schools, such as deputy principals, head of departments and teachers. Questionnaires were distributed, completed and collected personally. The questionnaires were analyzed and gaps such as the effects of lack of physical resources and how the learners’ profile were affected were reinforced by individual and group interviews that were semi-structured as ix well as participant observations from principals at O.R Tambo, Chris Hani and Amathole District Municipalities were conducted. It was deduced from the statistical data presented that there is a significant correlation between the principals’ management tasks and the quality of education. This shows that the more the principals blend properly planning, organizing, leading and control management tasks the more the physical resources will be managed better, that is, effectively, efficiently, economically and transparently and the less the bringing together of management tasks the less the meaningful management of physical resources will be. The study supported the hypothesis that a combination of management tasks performed by the principals positively influences the proper management of physical resources in rural secondary schools of ECP. The study rejects both null hypotheses that there is no significant correlation between planning, organising, leading and controlling as leadership functions of PRs and the quality of education in rural secondary schools of ECP as well as, that principals of rural secondary schools are not expected to possess adequate leadership knowledge and skills to effectively manage available PRs in their rural secondary schools. This study affirms the view that adequate physical resources are crucial as well as the appropriate management skills of principals for high quality education to be achieved in rural secondary schools. Without adequate physical resources, proper handling of the limited physical resources and the possession of management skills by principals, rural schools are less likely to succeed in their efforts to improve education.

- Description: This research engages with a contemporary theoretical debate in the literary field, namely the ability of fictional texts to contribute to archival records. Contemporary research in archival discourse suggests that there are many intersections between fiction and the archive. Using Hamilton and others’ seminal text Refiguring the Archive (2002) and Pasco’s “Literature as Historical Archive” (2004) as point of departure, this dissertation offers an analysis of the South African English translation of Marlene van Niekerk’s Agaat (2004, translated 2006). In both form and function, the novel is viewed as a simulation of an archive. In Agaat, Van Niekerk has compiled a fictional archive of two indigenous South African cultures through her portrayal of the two main characters: Afrikaner culture during apartheid as embedded in the focalization of Milla de Wet and remnants of Khoi and/or San culture as emerge from the fictionalised subjectivity of her coloured housekeeper-nurse, Agaat. Through a conceptual and theoretical exploration of archival discourse, I argue that literary texts, such as Van Niekerk’s novel, have the potential to refigure (or creatively redefine) the archive and to enhance its scope and relevance, especially as South Africa undergoes transformation.

- Description: The literature has indicated that nurses perceive more occupational stressors than do other professional groups. HIV is a new stressor which has impacted on society, in particular on people caring for HIV/AIDS patients. The availability of antiretroviral treatment (ART) which is accessible at wellness clinics has improved the quality of life of people with HIV and greatly prolonged the lives of many infected people. Wellness clinics are out-patient clinics where HIV positive patients receive their ART. This study has explored and described the occupational stressors perceived by nurses working in wellness clinics in Nelson Mandela Bay. The study was conducted using a qualitative research approach. Convenience sampling was used consisting of voluntary registered female nurses. The data were collected by means of semi-structured interviews. The interviews were audio-recorded and transcribed verbatim. The data were analyzed using Tech’s method. The nurses who participated in this study reported their perceptions of occupational stressors in wellness clinics where they worked. The occupational stressors perceived by the nurses included the working environment, interpersonal relationships and the organizational structure. However, they also reported that they experienced satisfaction from their jobs despite the perceived stressors.

- Description: The present study involves an exploration of the phenomenological expenence of posttraumatic growth in the context of a traumatic bereavement. An idiographic case study of a student who had witnessed her mother's death twelve years previously was conducted. Semi-structured interviews elicited data which was analysed using interpretative phenomenological analysis (IP A). Posttraumatic growth was found to have developed with regards to self-perception, relationships, and also in a broader spiritual and existential domain. The findings of this study shed light on the extant posttraumatic growth literature. In particular, findings were discussed in relation to the posttraumatic growth model as proposed by Calhoun and Tedeschi (2006). As posttraumatic growth is a relatively young concept, further research is needed in order to understand the meaning of reported growth more fully. While posttraumatic growth has been investigated in the context of bereavement, future research should distinguish more clearly between growth following traumatic and non-traumatic bereavement. Posttraumatic growth has received minimal empirical attention in South Africa, and therefore exploration of this area is suggested in the future. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Tabloid journalism has and continues to spark controversy. Scholarly considerations of tabloid journalism often question its contribution to democratic causes. However, little academic attention has been given to the question of how tabloids are understood and evaluated by their audiences. This study considered a range of audience responses to the Daily Sun by analysing the way some of its readers understand and evaluate it. The study examined the appeal of this popular tabloid to some Grahamstown readers. Reception analysis was employed to determine why these people read the Daily Sun. In particular, the active audience theory was used as a framework to conduct the research. To achieve the objectives of the study, qualitative research methods such as focus group interviews and individual in-depth interviews were employed. Looking at the findings, many of the respondents acknowledged they read the tabloid for interpersonal communication, diversion and entertainment. The results also revealed that their lived context plays a major role in their reading of stories. In a wider context, the research contributes to an understanding of the popularity of tabloid newspapers.

The possibility of psychotherapeutic privilege in South Africa

- Description: Privilege is an evidential principle which, on the grounds of public policy, excludes evidence relevant and otherwise admissible. This thesis aims to discover whether privilege should be applied to the psychotherapeutic profession in South Africa. At present, the only profession in South Africa afforded privilege is the legal profession. There are two main theoretical justifications for privilege: the utilitarian and the individual/human rights approach. This thesis considers whether the psychotherapeutic profession warrants privilege under either theory, and recommends that the law of privilege integrate both theories rather than adopt one or the other. The impact of the Constitution and the right to privacy receive particular attention. Very little literature or case law on the question of psychotherapeutic privilege was found in South Africa. Consequently, extensive comparative research into the common-law systems of England, Canada and United States of America was done. This research yielded some interesting findings. The first is that case-by-case development of the law of privilege is uncel1ain and fragmented. The next is that psychotherapeutic privilege exists in almost absolute form in the United States of America, but is littered with lacunae causing as much uncertainty as the case-by-case approach to privilege law. The most helpful method of dealing with the problem was found in Canada, where a two-stage approach to protecting personal information, including psychotherapeutic records, has been developed. In light of this research, this thesis reassesses the original viability of psychotherapeutic privilege in South Africa. Privilege, it was found, is not the best solution to protecting psychotherapeutic communications. This thesis recommends legislative adoption of an amended two-stage approach based on the Canadian model for sexual offence trials as the best method of protecting psychotherapeutic communications in both civil and criminal proceedings. The thesis ends by suggesting draft legislative provisions.

- Description: This study set out to explore the possibilities that the Critical Realist concept of a stratified ontology might have for environmental learning and materials development processes. This involved processes of ongoing contextual profiling; the use of picture-based resources and storytelling to support the engagement with the marine harvesting contexts of the villages of Hamburg and Ngqinisa, in the former Ciskei. At the heart of the study was the process of uncovering the empirical, the actual and the real in the context of a community of coastal marine harvesters whose lives and livelihoods are affected by poverty and a history of inequality, and more recently by issues such as HIV/AIDS. Their stories of existing practice changed as we engaged with picture-based narratives, gaining depth and focus in relation to sustainability issues. The learning processes associated with and emerging out of the research processes were enhanced through abductive use of metaphors and graphic illustrations, and through intra- and inter community exchanges, again using picture based narratives. As the study unfolded, the development of environmental education materials receded. Focus turned to how conceptual abstraction processes (of abduction (metaphor) and retroduction) and the stratified ontological framework allowed for learning across epistemological divides.
