- Description: In applying Pascale’s (1990) constructive ‘conflict paradigm’ to consider transformation efforts at a selected bank, this study argues that transformation could be sustained if the organisation were to self-reflect on the paradoxes that are generated when constructive conflict is encouraged. Underlying this supposition is the notion of “disequilibrium” which supports creative tension within organisations and prompts inquiry and dialogue, leading to the new. Sustaining disequilibrium allows an organisation to develop the “requisite internal variety” in order to meet the challenges in its environment. Key to encouraging this form of organisational resilience to its environment is the nature of the organisation’s culture or context. Johnson’s (1998) “cultural web” is used to analyse the culture of the selected bank and “re-map” the culture in line with the bank’s transformation strategies. Pascale’s seven domains of contention are applied with particular emphasis on the ATM division in order to develop a profile of conflict in the organisation.

- Description: The reaction of salicylaldehyde with various activated alkenes, viz., methyl vinyl ketone, ethyl vinyl ketone, phenyl vinyl sulfone, phenyl vinylsulfonate, acrolein and acrylonitrile, under Baylis-Hillman conditions, has been found to proceed with the chemoselective formation of chromene derivatives. The reaction conditions have been optimised and chromene derivatives have been obtained in isolated yields up to 87 %. The generality of the reaction, using 1,4-diazabicyclo[2.2.2]octane (DABCO), as the catalyst, and a heterogeneous (chloroform-water) solvent system, has been established using a range of salicylaldehyde derivatives,. including 2-hydroxynaphthaldehyde. The formation of chromene derivatives, under these conditions, has been assumed to proceed via an initial, Baylis-Hillman reaction, followed by cyclisation involving intramolecular conjugate addition, and subsequent dehydration. Evidence supporting this sequence has been obtained from the isolation ofBaylis-Hillman products from reactions involving the use of tertbutylclimethylsilyl-protected salicylaldehyde, 4-hydroxybenzaldehyde and tert-butyl acrylate as substrates. The potential of the ''Baylis-Hillman zwitterion" to participate as a donor species in Michael-type addition reactions has been explored and a series of climeric products has been isolated. The Baylis-Hillman methodology has also been successfully extended to the synthesis of sulfurcontaining heterocyclic systems, and a range of 3-substituted thiochromenes has been obtained in moderate yields, using 2,2'-dithiobenzaldehyde and various activated alkenes in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as catalyst. The electron-impact mass spectra of selected chromene and thiocbromene derivatives have been investigated permitting comparison of the fragmentation of the oxygen- and sulfur-containing analogues. In a study directed at the synthesis of potential HIV -1 protease inhibitors, chromene- and thiocbromene-containing analogues of the clinically useful drug, ritonavir, have been prepared. Thiochromene and chromene derivatives were converted to the corresponding 3 -carboxylic acids and coupled with a specially prepared, hydroxyethylene dipeptide isostere to afford ritonavir analogues containing cbromene and thiochromene termini in ca. 60% yield.

- Description: The Port Elizabeth Shakespearean Festival has good reason to remember the 23'd April. Quite apart from its being the official birthday of Shakespeare and St. George (after whom the park was named in which Mannville, the company's open air theatre, stands today), the 23'd April 1904 was the birthday of Leslie French, doyen of classical theatre in South Africa in the last century, whose productions established and consolidated open-air theatre in Port Elizabeth. He had a varied and successful career in the performing arts well before his association with South African theatre began. A gifted boy singer, his first appearance was in London at the Little Theatre, December 141", 1914, while he was still a chorister at the London College of Choristers. In the next four years he appeared regularly with Jean Sterling Machinlay and Harcourt Williams at the Margaret Morris Theatre, as a soloist at many important London churches (including St. Margaret's, Westminster Abbey and St. Paul's Cathedral), as well as singing at the Royal Albert Hall and the Queen's Hall in the Chapel Ballad Concerts.

- Description: This study investigates whether or nor not the imagery of Catherine of Siena can be interpreted from a Jungian perspective. It takes a lead from other studies, notably one on Teresa of Avila and Jung. Reading of medieval literature suggests that medievals applied the use of symbols and imagery in ways that are at times baffling to people of our time. Carl Jung was no stranger to imagery and symbol. In our current age with its renewed emphasis on the insights of spirituality, and to some extent its disenchantment with aspects of traditional psychology, there is room for a dialogue between the two disciplines of mysticism and psychology across a six-hundred year divide. The use of imagery, as a window to the soul, in the Christian tradition is examined. Catherine of Siena is situated within her own medieval context, one of upheaval in the church, but also an age of mysticism and spiritual/religious phenomena strange to our own time. Catherine is introduced against the background of her world and against the backdrop of the Dominican tradition. A discussion of some of her major imagery demonstrates her aim of union with God. An understanding of conscious aspects and of unconscious aspects of the self is shown as key to Jung ' s view of the psyche. Elucidation of some archetypes and a discussion of Jung's dream analysis demonstrates how Jung believed the unconscious becomes conscious, and how individuation becomes a possibility. Key Catherinian images are examined from a Jungian perspective. Catherine has relevance for the twenty first century, and we are invited to be challenged by the mysteries and truths to which her images point us.

- 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.

Behavioural interactions of predators and spawning chokka squid off South Africa: towards quantification

- 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.

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: 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.
