- Description: Effective change leadership is important to any organisation undergoing fundamental transformation. In particular, the ability of senior public sector leaders to successfully drive strategic change is crucial to meeting the developmental and service delivery challenges faced by the Province of the Eastern Cape in ensuring the effective, efficient and innovative government demanded by all its various stakeholders. The creation on 3 October of a Shared Legal Service situated in the Office of the Premier provided a unique opportunity to examine the leadership of this change initiative in the context of the organisational culture that existed in the provincial public service. This thesis consequently probes the phenomenon of effective change leadership by means of an examination of the understandings of the three change agents involved in driving the transformation of the provision of legal advisory services to the provincial administration and its constituent departments. The picture which emerges from the insights of the participants is one that casts a shadow over the validity of the contemporary theory of transformational leadership. Furthermore, the research conducted has identified the need to view the nature of effective change leadership through a more nuanced, situation-specific lens: one that appreciates the role of relationships and emotions, and that recognises the importance of culture and its impact on the success of organisational transformation. The case study of the Shared Legal Service change initiative provides useful insights into the many and varied challenges faced by public sector leaders in driving strategic transformation in the provincial administration. It offers an example of successful change leadership and demonstrates the need for change agents within the public service to harness more emotionally resonant and relational forms of leadership if they are to soar to new heights in meeting the service delivery expectations of all who look to provincial government to deliver the fruits of democracy.

- Description: During the first decade of democracy in South Africa formal education has been characterised by sweeping policy shifts and consequent curriculum revision. In many instances, curricular revisions are criticised for failing to effect desired or anticipated changes. In this chapter the focus is on the language curriculum and the associated practices, or what I refer to as the literacy practices that have become naturalised over decades and persist in the present. The argument that is presented here contends that to enable effective change, it is essential to understand better what has historically constituted literacy practices and to recognise their social, cultural and economic implications.

- Description: The National Water Act (1998) opens the way for ordinary people to take part in water resource management (WRM). This is a significant move towards a more social orientation and away from an approach that focused almost exclusively on the technical aspects of WRM. This set of two books asks what a social orientation means in practice. Since the National Water Act became law in 1998, how have WRM practitioners involved people in the process of managing water? What have we learnt so far? And how can we use these lessons to move forward? The content of the books is based on research that looked in some depth at national and local participatory practice in South Africa, and also broadly at international trends. The research was conducted by three WRM practitioners and two researchers in the field of participatory approaches.

- Description: When Rhodes University Library closed its LibQUAL+™ survey on 29 August 2005, it became the first of seven university libraries in South Africa to complete this Web-based survey, which measures library users’ perceptions of service quality and identifies gaps between desired, perceived, and minimum expectations of service. This paper focuses on the Rhodes Library’s implementation of the 2005 LibQUAL+™ survey. Results are looked at within the broader context of aggregate scores and score norms from the South African cohort. The library’s first efforts to address areas where perceptions of service quality differed from users’ expectations are described and plans for future efforts are indicated. The paper also details some lessons learnt by other LibQUAL+™ participants, as documented in published case studies.

Living condition in informal settlements: the case of Imizamo Yethu informal settlement in Cape Town, South Africa

- Description: The study examines the issue of living conditions in informal settlements, using the case study of Imizamo Yethu informal settlement in Cape Town. Affordability, lack of space, job related issues, a relatively small formal housing stock available in many urban centres, and deregulation, in terms of both access to land and finance, forced lower income groups to seek accommodation in informal settlements. Here people are exposed to unhealthy living conditions. The study reveals that living in informal settlements often poses significant health risks. Sanitation, food storage facilities and drinking water quality are often poor, with the result that inhabitants are exposed to a wide range of pathogens and houses may act as breeding grounds for insect vectors. In informal settlements people often live in temporary homes constructed with impermanent, basic materials. These inhabitants frequently have little option but to live on marginal land (flood plains or steep slopes, for example), with the consequence that they are the first to suffer the effects of cyclones and floods. In addition, a combination of overcrowding, the use of open fires and flammable buildings leads to danger from accidental fires, burns and scalding. The post-apartheid South African government has tried a number of housing initiatives to help alleviate the housing problem since 1994 when it came to power. These have included the Botshabelo Accord (1994), the Housing White Paper in 1995, the National Urban and Reconstruction Housing Agency in 1995, the Housing Subsidy Scheme in 1995, the Housing Act No. 107 of 1997 and the Policy on People’s Housing Process (1998). The government set itself a target of delivering one million houses within five years. By all indications the government did not fully comprehend the gravity of the problem in relation to available resources. In 2004, the Department of Housing declared its intention to eradicate informal settlements in South Africa by 2014. This followed the unprecedented housing backlog, proliferation of informal settlements, social exclusion and the inability of municipalities to provide basic infrastructure to urban poor households. However, despite these bold interventions by government, the study demonstrates that the provision of low-cost housing can be viewed as a wicked problem. Wicked problems are described to be “ill-defined, ambiguous, and associated with strong moral, political and professional issues”. The study, therefore, concludes that given the complexities surrounding the provision of low-cost housing in South Africa, the government’s ambitions to resolve housing backlogs by 2014 appear to be a far-fetched dream.

- Description: The purpose of this study is to look at instilling discipline of learners at schools after corporal punishment was abolished by identifying causes of disciplinary problems, alternatives to corporal punishment, and the attitudes of learners, teachers and parents towards alternatives. Data were collected through questionnaires, interviews and observation. Data were collected from learners, teachers and parents. Two neighbouring schools in the Mthatha District of Education were used. A qualitative research approach was used in the study. Findings reveal and support literature consulted that there is a wide range of causes of disciplinary problems at schools. According to the findings, the outstanding difference between respondents on causes of disciplinary problems was on home background. Learners are not in agreement with literature, teachers and parents who all agree that background is the cause of misbehaving of learners at school. The study reveals that learners, teachers and parents hold different views about alternatives to corporal punishment. While teachers, parents and literature are in agreement on using parental involvement as an alternative to caning, learners do not want parents to be involved. Teachers, the findings reveal, are not in favour of alternatives that need to be supervised by them. The final outcome of this study focuses on positive alternatives to corporal punishment. These include parental involvement, manual work, the application of school rules and enforcement of the code of conduct. Learners would also like to be disciplined and parents are in favour of being involved in the maintenance of discipline in schools.

Making sense of Men's Health: an investigation into the meanings men and women make of Men's Health

- Description: This study investigates the popular pleasures produced by readers of men's magazines, focusing primarily on the publication, Men's Health, which represents a new type of magazine catering for men. Using qualitative research methods such as textual analysis and reception analysis, the study explores the pleasures produced by both men and women from the consumption of such texts. The theoretical perspective of cultural studies informs this project, an approach that focuses on the generation and circulation of meanings in society. Focusing on the notion of the active audience and Hall's encoding/decoding model, this study examines readers' interpretations of the Men's Health text, focusing on the moment of consumption in the circuit of culture. Reception theory proposes the existence of "clustered readings" produced by interpretive communities that are socially rather than individually constructed. As a critical ethnography, the study interrogates these meanings with particular reference to questions of gender relations and power in society. Access to different discourses is structured by the social position of readers within relations of power and this study takes gender as a structuring principle. Therefore, this study also explores the particular discursive practices through which masculine and feminine imagery is produced by the Men's Health text and by its readers. The research findings support the more limited notion of the active audience espoused by theorists such as Hall (1980) offering further evidence to suggest that readers produce readings other than those preferred by the text and that therein lies the pleasure of the text for male and female readers. The research concludes that the popularity of Men's Health derives from the capacity of its readers to make multiple meanings of the text.

- Description: Over the past few decades, it has become widely recognized that the management strategies of world fisheries must ensure sustainability of bycatch as well as of target species. South Africa implemented a pilot observer programme from 1995 to 2000 to collect data on the levels and patterns of bycatch and discards in the demersal trawl fishery. Here, the results of that programme are used in conjunction with information on bycatch value and compliance to assess the issues and problems regarding bycatch and discarding in the fishery. In general, bycatch components can be placed into one of three categories (discarded bycatch, retained bycatch, and processing waste), each of which present different management problems and require different management approaches. The results were used to formulate a bycatch management plan for the demersal trawl fishery in South Africa. Given the need to continue monitoring bycatch, the performance of the pilot observer programme is reviewed, and the levels of sampling effort required for a national programme are discussed.

Manifestations of nihilism in selected contemporary media

- Description: This study focuses on the concept or phenomenon of nihilism, given the regularity with which it manifests itself (to anyone who is aware of it in more or less theoretical or philosophical terms) in all kinds of cultural artifacts such as films, television shows or series, books such as novels or philosophical texts, and magazines. Most of these artifacts can be grouped together under the heading of the media in the present era. The objective of the study is to use the concept of nihilism to identify and analyse selected cases in contemporary media -- in the form of films and television series – to answer the question, with what kinds of nihilism people would come face to face if they knew how to recognize them. The study begins with an outline of a theoretical framework concerning the concept of nihilism. A number of thinkers’ work is used to come to grips with the complex phenomenon, but mostly it is Nietzsche whose thought seems to be valuable for present purposes. In the second chapter the spotlight falls on what is called (in this study) ‘capitalist nihilism’, which seems to belong with what Nietzsche called ‘passive nihilism’, but also seems to exhibit some aspects of ‘active nihilism’. The third chapter is an examination of nihilism in a foreign (Japanese) culture by concentrating on Japanese anime, to test the differences between Western (historically Christian) culture and one with a different cultural and religious history. The last chapter consists of the analysis of a specific (Western) film, I ‘heart’ Huckabees, which was selected because of the variety of ‘nihilisms’ found in it. The study seems to confirm that nihilism is indeed widespread in contemporary, postmodern culture.

- Description: The security of its citizens is often regarded as the democratic state's primary raison d'etre. However, with increasing crime and perceptions of insecurity among citizens, along with actual and perceived state policing inadequacies, citizens around the world have sought to make alternative arrangements for their security. The explosion of private alternatives to state policing has resulted in the need for the replacement of former static definitions of policing by more fluid understandings of what policing entails. Policing is no longer an activity undertaken exclusively by the 'state police.' Policing needs to be understood within a framework which recognises the existence of a variety of state, commercial, community groups and individuals which exist within loose and sometimes informal, sometimes formal, networks to provide for the security of citizens. Preceding the country's transition to democracy in 1994 'state' policing in South Africa was aimed at monitoring and suppressing the black population and as a result it conducted itself in a largely militaristic way. When the government of national unity assumed power in 1994 it was indisputable that the South African Police had to undergo major reform if it was to play an effective, co-operative and accountable role in a democratic South Africa. While state policing has unquestionably undergone enormous changes since the advent of democracy in 1994, so too has non-state policing. It is widely accepted that the dividing line between state and non-state policing in South Africa is increasingly blurred. Policing, by its very nature, holds the potential to threaten democracy. Consequently it is important that policing is democratically controlled. According to the Law Commission of Canada four values and principles - justice, equality, accountability, and efficiency - should support policing in a democracy. This thesis is a case study of policing in Grahamstown, a small city in South Africa's Eastern Cape province. It will be shown that the policing problem that currently plagues Grahamstown, and by extension South Africa, is not simply the result of a shortage of providers but rather a problem of co-coordinating and monitoring security governance to ensure that the city does not further develop into a society where the wealthy have greater access to security than the poor.

- Description: This Portfolio was submitted in 2005 to Rhodes University as a Research Portfolio presented in partial fulfilment of the requirements for the degree of Master of Education in General Education Theory and Practice. The Portfolio consists of seven (7) key parts. The reader of this Portfolio is courteously informed that the structure of this portfolio is to some extent differ from the thesis structure. Thus, the reader should be attentive not to weigh against the two. Further more, I hereby declare that this portfolio is my own work and that all the sources that I have used or quoted have been indicated and acknowledged by means of references indicated at the end of each part. Part 2 and 6 are the core parts of the portfolio. The focal point of part 2 is the contextual curriculum analysis of Grade 8-10 Oshindonga Curriculum in order to investigate its implementation in four educational circuits: Oshigambo, Onathinge, Onyaanya and Omuthiya in Oshikoto Region. Based on the findings of this analysis, lack of critical inquiry and reflective practice among Oshindonga teachers was identified as one of the major obstacles that preventing the effective implementation of the curriculum. Most of these teachers are Basic Education Teacher Diploma (BETD) postgraduates. Thus, part 3 and 4 were developed as supplements to inform the main research paper (part 6) which is related to teacher's professionalism in the classroom. The focus of part 3 (literature review) was on the teacher as a reflective practitioner. This is in line with the Namibian Education Policy, which identifies reflective practice as the heart of teacher professionalism. In this part, I explored a variety of views related to the notion of professionalism in teaching. I have also focused on views related to teacher's professional development both on macro and micro levels. These views provided a clarification and an underpinning framework on which to base my analysis of reflective practice as professionalism in education. Part 4 (education theories) focused on the digging of understanding of knowledge as an important theoretical domain of behaviourist and constructivist theories. I have tried to establish how the two theories (Behaviourist and Constructivist) view knowledge and its acquisition and to gain an understanding of how the two theories have been informing the practice. Subsequently, part 6 meant to investigate and assess the extent to which Basic Education Teacher Diploma postgraduate teachers are autonomously applying the theory of critical inquiry and reflective practice in the classroom. Both part 2 and 6 have findings. There is much correlation between the issues and problems in the implementation of the curriculum as identified in part 2 and the findings of the main research paper (part 6). Though critical inquiry and reflective practice is the key journey towards a high level of reflectivity and one of the significant characters of teacher professionalism in the classroom, most issues and problems identified were related to the insufficient practice of critical inquiry and reflective practices. Low correlation was found between critical inquiry and reflective practice theory and teachers' practices in the classroom. Despite to the fact that various rationales were mentioned as to why critical inquiry and reflective practice successful implementation is not taking place, the study positioned an emphasis on team working at school, cluster and circuit base that could contributed to a great extend to making teachers more competent and supporting themselves in mastering the applicable critical inquiry and reflective practice skills.

- Description: This study examines the use of age-structured maximum likelihood and Bayesian approaches for stock assessment of the Namibian monkfish, Lophius vomerinus, resource with questionable data, in which time series are short, abundance indices are variable, and research data conflict with commercial data. Bayesian approaches with both noninformative and informative priors are investigated to determine if they enhance estimation stability. Three data scenarios are assessed: commercial and research survey data, research survey data only, and commercial data only. Both statistical approaches show that resource abundance has decreased with exploitable biomass estimated at approximately 44% of pristine levels. The maximum likelihood and the Bayesian approach with noninformative priors result in similar estimates. As the abundance data contained little information pertaining to possible density dependence within the stock–recruit relationship, only a Bayesian approach with informative priors reduces uncertainty in the steepness parameter h. Estimated management quantities are sensitive both to the set of data sources and whether prior information was informative or not. The strengths of the Bayesian approach include the integration of prior information with uncertain data, the exploration of data conflicts, and the ability to show the uncertainty in estimates of management parameters. Its weakness is that estimation stability is dependent on the choice of priors, which alters some posterior distributions of management quantities.

- Description: By exploring the views of editorial and business leaders in the media industry, the Sol Plaatje Institute for Media Leadership (SPI) aims to reach a comprehensive understanding of management training issues that are regarded as priorities by leaders in the SADC region. The Institute also aims to create a space for media organisations to share their experiences of management capacity building and explore avenues for future collaboration. It is envisaged that this report will form part of an ongoing dialogue on the needs of media leaders in the region. Representatives from the SPI, the Southern Africa Institute for Media Entrepreneurship Development (SAIMED), the Southern Africa Media Development Fund (SAMDEF) and the Southern African Media Training Trust (NSJ) met to advise the SPI on the industry’s key information needs. The research was then designed to focus on the identified needs. The research was conducted in three phases. In the first phase approximately 75 interviews were conducted with people holding diverse positions in a broad range of print and broadcast media institutions in Botswana, Malawi, Swaziland, Tanzania and Zambia. The second research phase comprised a workshop held for training providers and media professionals from the SADC region. Findings from the initial phase of the research were presented to workshop delegates for comment and debate. This allowed for the testing and triangulation of initial research findings. In response to comments by delegates, who thought that the research ought to have included countries where the lingua franca of business is not predominantly English, the study was extended to a second set of countries: Angola, Mozambique and the Democratic Republic of Congo. Interviews with 64 informants from this second set of countries constitutes the final phase of the research, Translators were used in this third phase, but other than that, there was a high degree of standardisation across all eight countries with the same methodological approach - including the selection of participants - being used in the first and third phases. As the research is predominantly qualitative, findings are context-specific and not generalisable. The overall impression portrayed by the study is a sense that media managers throughout the SADC region are struggling to overcome the constraints of having received little training other than that acquired in the workplace. There is also a sense that media leaders and managers thirst for the knowledge and skills that will enable them to continually improve and steer their organisations to success. The political and economic contexts of the research countries are, to differing extents, all problematic. Mozambique has the most liberal media climate out of all the countries researched and the Democratic Republic of Congo has the most repressed. But all of the countries suffer some degree of media repression, whether blatant or subtle. It is widely accepted that media plays a vital role in the development and mediation of democracy. With empowerment central to the democratic ethos, it is vital that media leaders and managers are themselves empowered to steer their organisations fairly, freely and effectively. This study contributes to the process by asking media professionals about their perceptions on what kinds of training their leaders and managers need and prefer so that training interventions can be appropriately targeted and designed. And so this research process serves to initiate what the Sol Plaatje Institute for Media Leadership foresees will be an ongoing collaboration with media industry leaders and managers in the SADC region: a cooperate effort to shape solutions to the considerable range of training and management capacity building needs revealed in this study. , Funded by the Netherlands Institute for Southern Africa (NIZA)

- Description: Background: Providing written medicines information is being legislated in an increasing number of countries worldwide, with the patient information leaflet (PIL) being the most widely used method for conveying health information. The impact of providing such information on adherence to therapy is reportedly unpredictable. Therapy for human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and related opportunistic infections usually involves polytherapy and complex regimens, both of which are risk factors for non-adherence. The objective of this study was to assess the impact of medicines information on adherence to chronic co-trimoxazole therapy in low-literate HIV/AIDS patients. Methods: Two different PILs were designed for co-trimoxazole tablets and were available in both English and isiXhosa. Participants were randomly allocated to a control group (receiving no PIL), group A (receiving a 'complex PIL') and group B (receiving a 'simple PIL' incorporating pictograms). At the first interview, demographic data were collected and the time, date and day that the participant would take his/her first tablet of the month's course was also documented. In a follow-up interview adherence to therapy was assessed using two methods; self-report and tablet count. Results: The medicines information materials incorporating simple text and pictograms resulted in significantly improved adherence to therapy in the short term, whereas a non-significant increase in adherence was associated with the availability of the more complex information. This was shown by both the self-reported assessment as well as the tablet count. Conclusion: This research suggests that appropriately designed written material can have a positive impact in improving adherence and, together with verbal consultation, are essential for enabling patients to make appropriate decisions about their medicine taking.

- Description: Type II diabetes is becoming a growing problem in developed countries worldwide. The median age for diagnosis was around sixty, but recent surveys have shown that the entire age distribution curve shifting left. The incidence of type II diabetes is thought to be parallel with the growing rate of obesity associated with an unhealthy western diet. Type II diabetes is an expensive disease to manage, it is for this reason that cheaper medication needs to be investigated in the form of traditional plants, such as Sutherlandia frutescens. Prescription medication, such as tricyclic antidepressants, may also increase body weight thereby playing a role in obesity. The cause of weight gain in such cases may go unrecognized or lead to cessation of the medication with or without the practitioner’s knowledge or approval. It is therefore necessary to investigate the causative agents responsible for the excessive weight gain. Drinking water containing extracts of S. frutescens or metformin was administered to two groups of eleven insulin resistant male Wistar rats. The insulin resistant control group received water without any medication. Rats were sacrificed after 8 weeks allowing for fasting blood glucose, insulin and tissue glycogen content determination. Glucose uptake was also determined using [3H] deoxyglucose. The effect of the medication and the diet on muscle post receptor insulin signaling proteins was determined through Western blots. Liver proteomics was also performed using 2-D electrophoresis. In a separate experiment 26 male Wistar rats were exposed to strepotozotocin toxin, 7 of these rats received intravenous insulin treatment, 7 rats received S. frutescens extract and 7 rats received a combination of both medications, the remaining 5 received no treatment and served as the control. Rats were sacrificed after 6 days allowing for fasting blood glucose, insulin and tissue glycogen content determination. Two groups of 14 male Wistar rats received amitriptyline or trimipramine (common tricyclic antidepressants) in their drinking water, the control group (30 rats) received water without any medication. The rats’ weight and food consumption was monitored throughout the trial and their oxygen consumption was also determined. Rats were sacrificed after 6 weeks or 14 weeks of medicinal compliance allowing for fasting blood glucose, insulin and tissue glycogen content determination. Glucose uptake was also determined using [3H] deoxyglucose. S. frutescens treatment normalized circulating serum insulin levels and significantly increased the rate of glucose clearance. Certain post receptor insulin signaling proteins were also significantly increased relative to the insulin resistant control group. 2-D electrophoresis identified the normalization of protein levels associated with the urea cycle. S. frutescens was also able to, independently; maintain normoglycaemic levels in the strepotozotocin treated group. The tricyclic antidepressants significantly increased blood glucose levels while significantly reducing tissue glycogen levels for both sacrifice periods. Serum insulin remained unchanged while a significant increase in insulin degradation and insulin degrading enzyme levels were found for both antidepressants. S. frutescens shows promise as a low cost antidiabetic medication for future use. Although the antidepressants did not promote weight gain, the increase in blood glucose levels may be cause for concern in patients with a pre-disposition toward developing diabetes.

- Description: Type II diabetes is becoming a growing problem in developed countries worldwide. The median age for diagnosis was around sixty, but recent surveys have shown that the entire age distribution curve shifting left. The incidence of type II diabetes is thought to be parallel with the growing rate of obesity associated with an unhealthy western diet. Type II diabetes is an expensive disease to manage, it is for this reason that cheaper medication needs to be investigated in the form of traditional plants, such as Sutherlandia frutescens. Prescription medication, such as tricyclic antidepressants, may also increase body weight thereby playing a role in obesity. The cause of weight gain in such cases may go unrecognized or lead to cessation of the medication with or without the practitioner’s knowledge or approval. It is therefore necessary to investigate the causative agents responsible for the excessive weight gain. Drinking water containing extracts of S. frutescens or metformin was administered to two groups of eleven insulin resistant male Wistar rats. The insulin resistant control group received water without any medication. Rats were sacrificed after 8 weeks allowing for fasting blood glucose, insulin and tissue glycogen content determination. Glucose uptake was also determined using [3H] deoxyglucose. The effect of the medication and the diet on muscle post receptor insulin signaling proteins was determined through Western blots. Liver proteomics was also performed using 2-D electrophoresis. In a separate experiment 26 male Wistar rats were exposed to strepotozotocin toxin, 7 of these rats received intravenous insulin treatment, 7 rats received S. frutescens extract and 7 rats received a combination of both medications, the remaining 5 received no treatment and served as the control. Rats were sacrificed after 6 days allowing for fasting blood glucose, insulin and tissue glycogen content determination. Two groups of 14 male Wistar rats received amitriptyline or trimipramine (common tricyclic antidepressants) in their drinking water, the control group (30 rats) received water without any medication. The rats’ weight and food consumption was monitored throughout the trial and their oxygen consumption was also determined. Rats were sacrificed after 6 weeks or 14 weeks of medicinal compliance allowing for fasting blood glucose, insulin and tissue glycogen content determination. Glucose uptake was also determined using [3H] deoxyglucose. S. frutescens treatment normalized circulating serum insulin levels and significantly increased the rate of glucose clearance. Certain post receptor insulin signaling proteins were also significantly increased relative to the insulin resistant control group. 2-D electrophoresis identified the normalization of protein levels associated with the urea cycle. S. frutescens was also able to, independently; maintain normoglycaemic levels in the strepotozotocin treated group. The tricyclic antidepressants significantly increased blood glucose levels while significantly reducing tissue glycogen levels for both sacrifice periods. Serum insulin remained unchanged while a significant increase in insulin degradation and insulin degrading enzyme levels were found for both antidepressants. S. frutescens shows promise as a low cost antidiabetic medication for future use. Although the antidepressants did not promote weight gain, the increase in blood glucose levels may be cause for concern in patients with a pre-disposition toward developing diabetes.

- Description: An integrated approach to the design of potential rutheniun-based metathesis catalysts is described, in which closely defined synthetic forays provide the focus and rationale for detailed computational and mechanistic studies. The ground-state geometry of a 1st-generation Grubbs catalyst has been explored at the molecular mechanics, semi-empirical and DFT levels, and the resulting structures have been shown to compare favourably with literature data and with the structure of a known crystalline analogue. The DMol³ DFT code has also been shown to represent accurately both the geometry of the corresponding co-ordinatively unsaturated monophosphine derivative, and the ligand dissociation energy associated with its formation. A DFT free-energy profile of the degenerate metathesis of ethylene has been generated, using a truncated model of the 1st-generation Grubbs catalyst, permitting location, for the first time, of the three expected transition states and providing new information regarding the rate-determining step. DFT methods have been used to facilitate the design of a tridentate camphor-derived ligand for use in the construction of a novel Grubbs-type catalyst. The phosphine ligand dissociation energy of the putative catalyst and the ethylene metathesis energy profile of a truncated model have also been studies at the DFT level. The attempted synthesis of the proposed ligand proceeded via a novel 8-bromocamphoric anhydride intermediate and afforded several unexpected and novel products, including a cisfused γ-Iactone, and a bromo camphoric acid derivative. Single crystal X-ray analysis of the latter reveals a chiral, polymeric H-bonded packing arrangement, rendering it suitable for chiral inclusion studies. Computational methods, including the GAUSSIAN-based GIAO NMR prediction technique, were used to support the structural characterisation of the novel camphor derivatives. DFT-Ievel computational analysis of the C-8- and C-9 bromination of camphor has afforded theoretical insights which permit the reconciliation of two earlier empirical explanations regarding the regioselectivity of these transformations; moreover, the theoretical results suggest that a third, previously disregarded factor, plays a significant role. A coset analysis, in conjunction with DFT-Ievel energy profiling, has also been used to resolve conflicting opinions regarding the origin of the major byproduct. Computed electronic parameters (CEP's) have been calculated for the anionic ligands involved in a series of 2nd-generation Grubbs-Hoveyda-type catalysts, and used to explain some apparently anomalous trends in catalyst activity. A linear relationship between ligand CEP's and selected ¹H NMR chemical shifts has also been demonstrated and used to identify a transient ruthenium complex in solution. The ability of the malonate di-anion to bind to ruthenium in a bidentate manner has been explored and demonstrated, under suitable conditions. DFT methods have been used to design and assess the ruthenium-chelating potential of a novel tridentate malonate derivative. A synthetic pathway to this ligand has been designed and several novel heterocyclic intermediates have been isolated and characterised. An NMR-based kinetic study of the Grubbs-catalysed self-metathesis of l-octene has been completed, and the effects of temperature, concentration and solvent variations on the kinetic parameters have been studied. Application of the Guggenheim method and a simplified mechanistic model has permitted the accurate calculation of pseudorate constants for the initiation and, for the first time, the propagation phase of the reaction. Theoretical studies of this reaction at the DFT and molecular mechanics levels have been shown to support previous assumptions regarding the selectivity and temperature-dependence of metallacycle formation.
