- Description: Alan Griffiths was born at Walton-on Thames, England in 1906. He was educated at Christ's Hospital and later at Oxford (under the tutelage of C.S. Lewis). At Oxford he read English literature and philosophy. After considerable inner turmoil he was converted to Christianity in 1931 and entered the Roman Catholic Church in 1933. As a novice Benedictine he was given the name Bede, and was finally ordained as a priest 1940. In 1955 Fr Bede went to India to start a Benedictine community with Dom Benedict Alapatt. He later moved to Kurisumala Ashram in Kerala, and finally, in 1968, to Shantivanam Ashram in Tamil Nadu. He died at Shantivanarn in 1993. Fr Bede was, and still is, regarded by many as a spiritual pioneer. This high regard stems from an appreciation of his spirituality which was rooted in a mystical experience of God. This thesis investigates aspects of Fr Bede's cosmic christology as they arise from his spirituality. The aim of this research is to show that Fr Bede’s cosmic christology that stems from an expression of a real mystical experience of Christ, as the source, sustainer and goal of the whole cosmos, offers both value and insight to Christian spiritual practice and the formulation of doctrine. What makes Fr Bede's spirituality so valuable is the manner in which he integrated East and West in his spirituality and person, coupled with his ability to draw upon that integration in reflecting and articulating his experience - which ultimately shaped his cosmic christology. In order to share his knowledge and experience of the cosmic Christ, Fr Bede draws upon linguistic and philosophical concepts from the East (and Hinduism in particular) as well as the language and theory arising from discoveries in the areas of quantum physics, microbiology and transpersonal psychology in the West. It is the primacy of spiritual experience, coupled with Fr Bede's ability to integrate the religions, cultures and world-views of the East and West within himself, which makes his cosmic christology so compelling.

- Description: The main objective of monetary policy is to protect the value of the currency, and in so doing, achieve the objectives of maximum economic growth, development, and the creation of employment opportunities. As from 1985, under the advice of the De Kock Commission, the South African Reserve Bank (SARB), implemented the classical cash reserve system of monetary control. Under this system, the SARB was willing to refinance the money market shortage fully, automatically, and on certain predetermined terms, conditions and costs. However, since the new political dispensation in 1994, South Africa’s financial markets have become more globalized, liberalised, and integrated. Thus, the classical cash reserve system had lost its usefulness, and was no longer effective. As from March 1998, the SARB implemented the new repurchase system of monetary control. In implementing the repurchase system of monetary control, South Africa was adopting a more eclectic approach. This system is aimed at making monetary policy more effective and more flexible in a financial environment filled with complexities. This study finds that the repurchase system has thus far been successful in meeting its objectives. Interest rates are more flexible and sensitive to developments in the domestic and external environment, the signalling mechanism of the SARB has proved to be successful, accommodation and interest rates are closely related and the interbank market has become more developed. Therefore, the repurchase system appears to be more efficient than the previous system of monetary control in South Africa.

- Description: Nudaurelia beta virus (NβV) is a monopartite genome virus belonging to the family Tetraviridae. Its host range has been found to be limited to a single insect order, the Lepidoptera (moths and butterflies). The single-stranded positive-sense RNA genome consists of 6625 nucleotides containing two open reading frames (ORFs). The 5' proximal ORF of 5778 nucleotides encodes a protein of 215 kDa containing three functional domains characteristic of RNA-dependent RNA polymerase. The 3' proximal ORF, of 1836 nucleotides, encodes the 66 kDa capsid precursor protein and overlaps the replicase gene by more than 99% and is in the +1 reading frame relative to the replicase reading frame. The full-length cDNA construct of the NβV genome was assembled using a homologous overlapping PCR linking method. The starting material consisted of seven overlapping pieces that were constructed for sequencing. Due to the degradation of the full-length RNA obtained from virus extracted from field-collected Nudaurelia cytherea capensis larvae other alternative methods needed to be applied. Sub-cloning using restriction enzyme sites also required an alternative method being used, due to the abundance of restriction sites of the same type in the NβV genome. This led to the use of a method similar to "DNA Shuffling" where overlapping pieces were connected using a modified PCR protocol. After the construction of the NβV genome, the full-length PCR product was cloned and checked for large insertion and deletions that could have resulted from the PCR amplification. The heterologous expression of the NβV capsid protein linked to a fusion protein (Glutathione S-transferase) in E.coli, confirmed the authenticity of the prescribed capsid gene ORF. The expression showed that the virus protein was subjected to protease digestion in DH5α E.coli, suggesting that the protein was insoluble in the cell cytoplasm. The capsid gene expression in a modified E.coli strain, Epicurian Coli BL21-CodonPlus (DE3)-RIL, resulted in high levels of the correct molecular weight protein with minimal degradation. The modified strain was designed for over-expression of eukaryotic protein with lowered protease activity. The above results have opened the way for further research that would yield valuable insight into the molecular biology and replication strategy of the NβV in cell cultures.

- Description: This treatise takes the form of an impact study. It is based on a three-month period of research involving literature review, interviews with VWSA officers and a survey of 111 of the 5500 workers who comprised the workforce of the VWSA plant in Uitenhage at that time. The author has attempted to portray the general views of experts in the field of HIV/AIDS corporate impact and impact management. In addition he has attempted to assay the current and forecast policies and practices in respect of the management of the epidemic by VWSA. The workers in the plant were consulted by survey and a variety of insights into the level of understanding of the epidemic, tolerance levels, expectations and so on were made. The quantification of these insights must be viewed with caution since the survey sample of 111 was relatively low for a workforce of circa 5500. Calculations in respect of representativity are included to facilitate calculated caution. It has been shown that the HIV/AIDS epidemic has a considerable current impact on the company and that this impact can be expected to grow considerably in the future. It has been suggested that an active intervention program would be well timed if implemented immediately

- Description: In this research paper a database of accommodation establishments was compiled, and certain supply and demand aspects of the tourism industry in the George / Wilderness area were measured with a view to determine whether planning by the private sector and local authorities could benefit therefrom. Attention was given to the peculiar nature of tourism demand and tourism supply and how selected components thereof could be measured. The research methodology followed included: a literature survey to facilitate an understanding of the nature of tourism supply and tourism demand; the construction of a database of accommodation establishments in order to identify all participants in the George / Wilderness tourism industry; a telephone survey to determine the supply of bed nights in the area; and a questionnaire survey to determine the demand by tourists for bed nights in the area. The following recommendations and conclusions were made: The database compiled during this study should be kept up to date and be expanded to include visitor profiles such as country of origin, length of stay, and primary reason for travel in order that private and public sector concerns may draw statistics / data to be used in the planning and / or marketing of the tourism industry to tourists. Greater co-operation and co-ordination between private and public sectors of the tourism industry are needed to obtain data concerning the tourism market required for planning purposes as well as a concerted marketing effort. Failing this, legislation should be introduced, compelling accommodation establishments to make available supply and demand data to the regional services council for statistical purposes. The study should be extended to cover the entire Southern Cape region in order to obtain statistics applicable to the region as a whole. This will then facilitate both local and regional planning as well as a coordinated marketing effort.

- Description: This study explores the question of religion and ethnicity as a source of family diversity and ideology. An ideal-typical "traditional Muslim family ideology" was developed and tested. Eight Indian Muslim students at Rhodes University were asked about their attitudes and perceptions of marriage and family life, to determine the particular type of family ideology that these students embraced. Family-related issues such as marriage; the division of labour; gender roles; the extended family system; divorce; and polygamy were addressed. On the basis of the research results, it was found that these students largely adopted the "traditional Muslim family ideology". Religion and ethnicity were found to play an important role, in the make-up of these students' perception of marriage and family life, and a strong preference for the extended family was shown.

- Description: Bandwidth management is a topic which is often discussed, but on which relatively little work has been done with regard to compiling a comprehensive set of techniques and methods for managing traffic on a network. What work has been done has concentrated on higher end networks, rather than the low bandwidth links which are commonly available in South Africa and other areas outside the United States. With more organisations increasingly making use of the Internet on a daily basis, the demand for bandwidth is outstripping the ability of providers to upgrade their infrastructure. This resource is therefore in need of management. In addition, for Internet access to become economically viable for widespread use by schools, NGOs and other academic institutions, the associated costs need to be controlled. Bandwidth management not only impacts on direct cost control, but encompasses the process of engineering a network and network resources in order to ensure the provision of as optimal a service as possible. Included in this is the provision of user education. Software has been developed for the implementation of traffic quotas, dynamic firewalling and visualisation. The research investigates various methods for monitoring and management of IP traffic with particular applicability to low bandwidth links. Several forms of visualisation for the analysis of historical and near-realtime traffic data are also discussed, including the use of three-dimensional landscapes. A number of bandwidth management practices are proposed, and the advantages of their combination, and complementary use are highlighted. By implementing these suggested policies, a holistic approach can be taken to the issue of bandwidth management on Internet links.

- Description: The interaction of a suite of predators with mating and spawning chokka squid (Loligo vulgaris reynaudii) was studied at inshore (<50 m) spawning grounds off South Africa. This study provides the first detailed records of predator–prey interactions of squids on their spawning grounds and is the first attempt to time disruptions caused by predators to the egg-laying behaviour of squids, thereby quantifying the perceived threat to the prey. The squids are focused on mate choice and reproduction while they aggregate over egg beds and they may be more vulnerable to predation than at other times. Their vulnerability to different predators in the field is examined and the tactics used against different predatory species are illustrated using recordings made with underwater video cameras. Predators recorded included two cephalopods (Octopus vulgaris and L. v. reynaudii), five teleosts (Pagellus bellotii natalensis, Spondyliosoma emarginatum, Pachymetopon aeneum, Cheimerius nufar and Pomatomus saltatrix), seven chondrichthyians (Squalus megalops, Mustelus mustelus, Carcharias taurus, Dasyatis brevicaudata, Gymnura natalensis, Poroderma africanum and P. pantherinum) and three marine mammals (Arctocephalus puscillus, Tursiops aduncus and Delphinus delphis). Analysis of behavioural interactions between predators and prey showed that predator disruption of egg laying may be quantified in terms of time. Marine mammals caused the most acute disruption, whereas other taxa had more chronic disruption effects because they spent more time on the spawning grounds. During November 1995, the suite of predators changed during the course of a 2-day period of underwater video recording, possibly because of an increase in water temperature. The hypothesis that predators would be concentrated around a spawning aggregation was tested by surveying the spawning ground using an underwater camera towed by a boat navigating with differential GPS. The results supported the hypothesis because predators were located only around the spawning sites. The serial spawning of chokka squids in recently upwelled water may reduce predation pressure. Furthermore, it may be difficult for predators to predict the specific spawning site on a particular day because squids disperse away from egg beds at night and use numerous spawning sites along the coast.

Furthermore, it may be difficult for predators to predict the specific spawning site on a particular day because squids disperse away from egg beds at night and use numerous spawning sites along the coast.

- Description: Colin Lewis was Professor of Geography at Rhodes University, Grahamstown, South Africa from 1989 until his retirement at the end of 2007. In 1990, with the strong support of the incumbent Vice-Chancellor, Dr Derek Henderson, he instigated the Certificate in Change Ringing (Church Bell Ringing) in the Rhodes University Department of Music and Musicology - the first such course to be offered in Africa. Since that date he has lectured in the basic theory, and taught the practice of change ringing. He is the Ringing Master of the Cathedral of St Michael and St George, Grahamstown, South Africa. , The first ring of bells in Africa was installed in Grahamstown Cathedral in 1879 at the instigation of Frederick Henry Williams. Williams was Dean of Grahamstown from 1865 until his death in 1885. He was born in County Fermanagh, Ireland, not far from Enniskillen, where an octave was installed in the Cathedral when Williams was an impressionable 12-year old. Grahamstown's bells were also an octave, cast by John Warner and Sons of London. They were hung in the newly built tower, designed by the English architect, George Gilbert Scott.

- Description: Against the background of culture bound syndromes and the universalism/relativism debate, this research set out to investigate the diagnosis of brain fag syndrome by examining case studies in a South African context. Diagnostic criteria were identified by way of an analysis of the symptoms reported by a convenience sample of 20 black students experiencing problems related to study. In-depth case studies were conducted with three of the participants from the sample who most thoroughly met the criteria for brain fag syndrome. In a comparison between the brain fag diagnoses and the DSM-IV diagnoses, it was established that while the DSM-IV was not without merit in a cross cultural context, cultural differences were found which suggested the usefulness of the brain fag syndrome diagnosis. A speculative statement on the universalism/relativism debate was proposed based on the principle of complementarity derived from Quantum physics.

- Description: In most developing countries, community based natural resource management (CBNRM) initiatives have been adopted in an attempt to address the issue of environmental sustainability. This has largely come about due to an increasing recognition of the ineffectiveness of the state to achieve such sustainability. Within the South African context, recent policies have been drafted that aim to achieve these outcomes, which strongly articulate the need for the participation of local people in the management of natural resources both within communal areas and on state-owned land. The objectives of new policies, however, are not being met in the Eastern Cape of South Africa for the following key reasons: the insufficient recognition of the impact of past historical and political upheavals experienced within the former homelands’ situation; the government’s inability to process land applications; the government’s lack of ability and capacity to implement these policies; and frustratingly high levels of hierarchy at both the local and national level. The Masakane community, a group of former farm workers from the former Ciskei homeland in South Africa, are attempting to implement CBNRM initiatives. The Masakane case study reveals the urgent need to develop, implement and enforce new institutional and managerial arrangements, because without such arrangements state policies are unlikely to be implemented at the grassroots level.

- Description: The financial industry and more specifically Retail banking is a very competitive industry. The profit margins are shrinking with the entrance of newcompetitors into the market place. During the last two to three years various foreign banks have opened offices in South Africa, cherry picking the high net worth customers fromthe traditional high street banks. The product range between these banks is the same, maybe at times presented in a different wrapping. The one differential factor between the various banks is service and the quality thereof. The researcher, being a banker, decided to investigate how to improve the quality of service which is the main problemof this study. The secondary problems or subproblems are: * How to solve service breakdown? * How to retain customers after a service breakdown? The researcher first did a literature survey focusing on the key drives of this research namely: * Improving quality service. * Problem resolution. * Customer retention. An empirical investigation was also undertaken focusing on the personal market segment and the high net worth individuals. The demarcation of the survey was restricted to a specific area on the South Coast of KwaZulu Natal, and in particular the retail market and three specific branches on the South Coast, namely: * Scottburgh; * Margate, and * Port Shepstone. The main finding of the empirical survey indicates an average service rating of 8.38, which is in excess of the financial institution’s national service objective of 8.22 for 2001. This indicates that in most areas the service quality of this financial institution is good. The results fromthe literature survey as well as the empirical investigation indicated that service quality can only be achieved through a collective effort from all role players within the bank. The resolution of service breakdown needs to be controlled and managed to rectify breakdowns effectively within specific time limits that are acceptable to the individual customer. The barriers to retain customerswill become less effective should the financial institution not be able to restore or improve service quality for their customers.

- Description: This study aimed at focusing on the challenges facing probation officers working with young persons in conflict with the law, in the Eastern region, which forms part of the Eastern Cape Province. The main purpose of the study was to explore the experiences of probation officers in terms of the legislation that they are using when making decisions pertaining to young persons and the types of programmes that they offer to young persons for diversion and prevention purposes. The researcher also wanted to generate a greater understanding of the resources which probation officers have and need in order to run their programmes successfully to young persons, as well as to explore their feelings about working with young persons. The researcher did some literature review in relation to this field, where it became evident that probation services in respect of young persons in conflict with the law, is a relatively new field of specialisation in South Africa. This field started around 1995 as a result of the Inter - Ministerial Committee (IMC) on young people at risk, which was set up to respond and manage the crisis of more than one thousand children who were released from prisons and police cells. The IMC then, identified probation officers as leading role players in dealing with young persons in conflict with the law. An exploratory (non - experimental) design was used to carry out the research. A qualitative research method was also used as it attempts to describe and explain social reality from the points of view of the participants. This is because the researcher was interested to find out the experiences of probation officers in relation to their work with young persons. A non - probability purposive sample of all (11) probation officers was used. A semi - structured interview schedule with both closed and open - ended questions was used to collect data. All the information gathered from those personal interviews, was analysed by hand because the researcher wanted to interpret and produce social explanations. The findings of this small - scale study have revealed that there are a number of challenges facing probation officers. For example presently there is no comprehensive legislation for the management of young persons caught up in the criminal justice system. Instead, limited provisions are spread throughout a number of separate statutes, which make it difficult for probation officers to apply them. This study has also revealed that there is a shortage of human and material resources, which somehow impact negatively on how probation officers render services to their clientele. All probation officers in this study have positive feelings and attitudes about their work despite the fact that there are some challenges facing them that need to be addressed. Specific recommendations have been made based on the findings of this study, which could contribute to the development of probation services in respect of young persons in conf lict with the law

- Description: An audit report by the Australian National Audit Office (ANAO) indicated that a company needs to ensure that support is provided to those employees who remain after a staff reduction process and that their needs are managed effectively. One of the recommendations by ANAO for companies that are embarking on restructuring and future staff reduction programs, is the facilitation of change management workshops, or intervention to prepare the staff to manage change. A literature study revealed that no change management model existed that specifically focused on the “survivors” of a retrenchment or restructuring strategy in a company. The literature study was therefore used to assist in developing a change management in Telkom SA. Pre-assessment and post-assessment questionnaires were developed to test the employees’ abilities to manage change and their understanding of the changes that the telecommunications industry is facing. The findings of the survey showed a high level of employee tolerance to change and illuminated the value that was added by the developed change management model.

- Description: Eidolon helvum (Megachiroptera) is a large frugivorous bat found in equatorial and tropical Africa. The reproductive cycle is characterized by a three-month period of delayed implantation and the total length of pregnancy may be as much as 10 months. A histochemical study of the gonadotrophs and mammotrophs of the anterior pituitary, in conjunction with assays of LH-like, progesterone-like and prolactin-like immunoreactivity in the plasma suggest that during delayed implantation the gonadotrophs were inactive while the mammotrophs were active and plasma PRL-like immunoreactivity high. We interpret this as indicating that, in the straw-coloured fruit bat, implantation was inhibited by high levels of prolactin and, as such, the endocrine control of delayed implantation may be quite different from that described for other mammals.

- Description:
This study has focussed on several aspects of chromone chemistry, viz., (i) the influence of remote substituents on the basicity of 2-(N,N-dimethylamino)chromones, (ii) MoritaBaylis-Hillman reactions of substituted chromone-3-carbaldehydes and (iii) an investigation into the application of chromone chemistry in the total synthesis of the marine natural product, Rietone A. Selected 2-(N,N-dimethylamino )chromones were prepared using two different methods; firstly, via cyclisation of salicylate-derived N,N-dimethyl-3;.(2-hydroxyphenyl)-3- oxopropanamide precursors and, secondly, via 2-hydroxyacetophenone boron difluoride complexes. ¹³C NMR analysis of the 6- and 7-methoxy-2-(N,N-dimethylamino)chromones confirmed that protonation occurs at the chromone carbonyl oxygen rather than the amino nitrogen - a conclusion supported by mol~cular orbital calculations. Potentiometric analysis of 2-(N,N-dimethylamino )chromones in ethanol-water afforded pKa (pK [subscript a]) values in the range 2.22 - 2.52. The observed trend has been rationalised in terms of substituent effects with the aid of molecular orbital calculations at the semi-empirical and ab initio levels, while hydrogen-bonding effects have been used to account for the apparently anomalous result obtained for the 6-nitro derivative. A series of seven substituted chromone-3-carbaldehydes, prepared by the application of Vilsmeier-Haack methodology to the corresponding 2-hydroxyacetophenones, have been examined as substrates for Morita-Baylis-Hillman reactions, using DABCO as the catalyst and three different activated alkenes, viz., methyl acrylate, methyl vinyl ketone and acrylonitrile. In all cases, with the exception of 6-nitrochromone-3-carbaldehyde, the reactions have been shown to afford the expected Morita-Baylis-Hillman products. Use of methyl acrylate and methyl vinyl ketone as the activated alkene has been observed to afford additional, unprecedented dimeric products, which have been unambiguously characterised using a combination of single crystal X-ray analysis and spectroscopic (high resolution MS and NMR) techniques. Different dimer-like adducts have been isolated from reactions in which acrylonitrile was used as the activated alkene, and the structures of these novel products have-been determined

Selected 2-(N,N-dimethylamino )chromones were prepared using two different methods; firstly, via cyclisation of salicylate-derived N,N-dimethyl-3;.(2-hydroxyphenyl)-3- oxopropanamide precursors and, secondly, via 2-hydroxyacetophenone boron difluoride complexes. ¹³C NMR analysis of the 6- and 7-methoxy-2-(N,N-dimethylamino)chromones confirmed that protonation occurs at the chromone carbonyl oxygen rather than the amino nitrogen - a conclusion supported by mol~cular orbital calculations. Potentiometric analysis of 2-(N,N-dimethylamino )chromones in ethanol-water afforded pKa (pK [subscript a]) values in the range 2.22 - 2.52. The observed trend has been rationalised in terms of substituent effects with the aid of molecular orbital calculations at the semi-empirical and ab initio levels, while hydrogen-bonding effects have been used to account for the apparently anomalous result obtained for the 6-nitro derivative. A series of seven substituted chromone-3-carbaldehydes, prepared by the application of Vilsmeier-Haack methodology to the corresponding 2-hydroxyacetophenones, have been examined as substrates for Morita-Baylis-Hillman reactions, using DABCO as the catalyst and three different activated alkenes, viz., methyl acrylate, methyl vinyl ketone and acrylonitrile. In all cases, with the exception of 6-nitrochromone-3-carbaldehyde, the reactions have been shown to afford the expected Morita-Baylis-Hillman products. Use of methyl acrylate and methyl vinyl ketone as the activated alkene has been observed to afford additional, unprecedented dimeric products, which have been unambiguously characterised using a combination of single crystal X-ray analysis and spectroscopic (high resolution MS and NMR) techniques. Different dimer-like adducts have been isolated from reactions in which acrylonitrile was used as the activated alkene, and the structures of these novel products have-been determined

- Description: South Africa's current industrial policy focuses on the economy at two levels: a sectoral and spatial level. The former relates to the manner in which industrial policy is concentrating on particular sectors i.e. industrial clusters. This shift in industrial policy from targeting individual industries to an emphasis on industrial clusters, has complemented the change in focus to export promotion under trade policy. Furthermore, there has been increasing recognition of the need to improve industry performance and competitiveness in order to successfully implement export growth. Industry clusters are considered as having the potential to increase manufacturing performance and can provide the basis for sustainable competitive advantage for nations. Consequently the concept of industry clusters was introduced in South Africa in 1997. Because industry clusters are relatively new in South Africa, most of the cluster initiatives in various sectors of the economy are in their early stages of development. Nevertheless, some are already showing signs of potential success in increasing competitiveness in particular sectors. This thesis uses Porter's "diamond" framework apprdach to investigate whether clustering has improved the manufacturing performance of the motor industry in the Eastern Cape. International experience from both developed and developing countries will illustrate the potential of clustering as a powerful strategy in increasing manufacturing performance and consequently competitiveness. Ultimately this should lead to long-term economic development, especially if government adopts clusterbased economic development policies. Information from a survey conducted on both the motor vehicle assemblers and component suppliers is used in this study. The findings reveal that it is mainly the motor vehicle assemblers who have experienced some improvements in manufacturing performance. The components sector on the other hand has not experienced any such improvements. This thesis concludes with the recommendation that it is important to develop cluster policy as a broader and dynamic view of competition. The main emphasis under such policy would be a move from targeting particular industries and providing subsidies towards focusing attention to all clusters in the economy. To effectively apply such a policy requires the repositioning of national, local and provincial government in order to become more involved in regional development issues. Moreover, the various levels of government need to incorporate cluster policy into their competitive strategies.
