- Description: Natural rangelands provide a variety of ecosystem services including livestock production which occurs on land under freehold land tenure and on land under communal tenure. There is an ongoing debate around the extent to which land degradation is occurring on these rangelands under different land management and land tenure systems and what the main degradation drivers are. Over-grazing, rainfall and soil type are key drivers of rangeland dynamics and the resultant sediment yield in the river systems, however, over-grazing is an outcome of land management while rainfall and soil type are natural drivers. This study explores the relationship between rainfall and daily sediment flux as well as the seasonal trends of vegetation cover and the study is part of a greater research effort called the Tsitsa Project which is based in the Tsitsa River catchment (near Maclear, Eastern Cape, South Africa). The Tsitsa Project aims at developing and managing both land and water in a sustainable way by improving the land, water and lives of people living in the Tsitsa River catchment. The restoration efforts of the Tstisa Project will aid in extending the lifespan of both the proposed dams on the Tsitsa River. The Tsitsa River catchment is characterised by grasslands, steep topography, highly erodible soils with many large gullies present and a very high sediment yield in the Tsitsa River which allowed for the exploration of some of the system drivers of sediment yield in this catchment. The study involved two sub-catchments of the Upper Tsitsa River catchment of different land management strategies: one dominated by commercial livestock farms (Little Pot River catchment) and one dominated by communal rangelands (Gqukunqa River catchment). The aim of this study was to determine the seasonal trends of rainfall intensity, ground cover and sediment dynamics in the Little Pot River and Gqukunqa River catchments. The purpose of the findings was to improve management strategies in degraded areas and catchments. In order to achieve this aim a variety of field and desktop methods were used. Field methods involved measuring variables including: vegetation biomass, vegetation cover, soil surface hardness, biocrust cover and slope angle for a range of Normalized Difference Vegetation Index (NDVI) values from the Sentinel-2A sensor. The study assessed the system response of the field variables in both catchments over one rainfall season (2018-2019). Desktop methods included various NDVI analyses as well as analyses of trends and relationships between vegetation dynamics, rainfall and sediment. The relationship between erosive rainfall events, daily rainfall, antecedent rainfall and daily sediment flux was explored over the time period of January 2016 to January 2019 and October 2015 to January 2019 for the Little Pot River catchment and the Gqukunqa River catchment respectively. NDVI was explored as a proxy for vegetation cover to extrapolate across the catchments and monitoring period. NDVI was found to have a weak positive relationship with vegetation cover and biomass (R2 values ranged from 0,04 to 0,525). Mean monthly catchment NDVI values, biomass and vegetation cover increased throughout the wet season of 2018-2019 in both catchments. Mean monthly NDVI values increased from 0,26 to 0,55 in the Little Pot River catchment and from 0,29 to 0,53 in the Gqukunqa River catchment over the course of the 2018-2019 wet season. NDVI, biomass and vegetation cover was found to be higher on south-facing slopes than north-facing slopes in both catchments for the majority of the wet season. The Gqukunqa River has significantly higher daily sediment fluxes than the Little Pot River despite similar NDVI and rainfall intensities which is owed to the dispersive soils in the Gqukunqa River catchment. Soil surface hardness results were inconclusive due to rainfall before or during every field trip which changed the properties of the soil. The largest erosive rainfall, daily rainfall and daily sediment events occurred from January to March each wet season in both catchments. Rainfall intensity and sediment fluxes were found to have a weak relationship, however, there was a stronger relationship found between antecedent rainfall and sediment flux. The larger daily sediment fluxes in each catchment often did not result from an erosive rainfall event on the same day but rather from multiple days of rainfall which can result in saturated soils and runoff leading to surface and sub-surface erosion. The possibility of sub-surface erosion via chemical processes contributing to the larger sediment events was also explored to explain the stronger relationship between antecedent rainfall and daily sediment flux.

It makes use of the distillation and fragmentation of these forms to explore themes such as the nature of violation, and works between genres to engage the tension between inner and outer realities, and the blurred lines between passivity and resistance. Moving fluidly between memoir and fiction and set in modern day South Africa, it draws inspiration from both my own experiences and the writing of others, especially Raul Zurita’s resistance poetry in Dreams for Kurosawa, Claudia Rankine’s subtle absurdity in Don’t Let Me Be Lonely, bizarro elements as seen in Athena Villaverde’s The Clockwork Girl and the use of physicality to explore the emotional world, as seen in Shelley Jackson’s The Melancholy of Anatomy: Stories.

- Description: Dolphins are apex predators and their movements, foraging activities and population dynamics play an important role in shaping their environment. Understanding their occurrence, movement patterns, and trophic ecology is essential to their conservation, especially as they are considered sentinel species. The Wild Coast of South Africa’s Eastern Cape, is characterized by the annual sardine (Sardinops sagax) run, which serves as an important foraging event for apex predators, including Indo-Pacific bottlenose (Tursiops aduncus) and long-beaked common dolphins (Delphinus delphis). Despite the ecological significance of this event, no dedicated surveys for these species have previously been conducted in this area. The main objectives of this research were to: investigate long-term occurrence of dolphins during the sardine run to determine if there have been any changes over the past 19 years, as has been predicted from common dolphin dietary investigations and anecdotal evidence; to determine short-term occurrence and movement patterns of selected inshore delphinids within the area, which is characterized by three marine protected areas (MPAs); and to use stable isotope analyses to determine trophic relationships and population structure of bottlenose and common dolphins within the region. Long-term data consisted of 131 opportunistic aerial surveys conducted between May and July over the period 1996 to 2014. Results from these surveys indicate that common dolphins, typically associated with sardines, decreased significantly in average group size over the study period (p=0.0343). Bottlenose dolphins, demonstrated no such trend (p=0.916). For both species, greater majority (> 70% of total counts) of sightings were made inside the MPAs. Short-term boat-based surveys were conducted three times a year between June 2014 and December 2016, contributing to a total of 47 days of surveys divided into three locations: Amathole, Hluleka, and Pondoland, each containing a MPA. Density and group size data were analyzed for both species and photographic identification analysis was performed for photographs of bottlenose dolphin dorsal fins. Results indicate that animal and sighting density did not differ temporally (bottlenose dolphin: sighting density – p=0.398, individual density –p=0.781; common dolphin: sighting density –p=0.472, individual density – p=0.204). Environmental factors (sea surface temperature, depth, substrate, and distance from shore) appeared to have limited effect on individual and sighting density and group size for both species (p>0.05). Photographic identification of bottlenose dolphins resulted in 2149 individuals, with a 11.8% resighting rate, with the highest resighting rate within the Pondoland MPA (16.1%). The resighting count did not differ temporally between monthly survey based on generalized linear models (p=0.866), but did differ between study areas (p<0.0001). These results provide the first evidence of the occurrence of both species of dolphin off the Wild Coast, as they were sighted in this region in all survey months. There was no trend in density based on temporal or environmental factors, which suggests other factors are influencing their occurrence. Resightings of bottlenose dolphins within the area suggest that there is some degree of residency, though the majority of animals were only sighted on a single occasion and there was no plateau in the discovery curve. A total of 256 biopsy samples (bottlenose dolphins =128; common dolphins=128) were collected during boat-based surveys. Bottlenose dolphin samples were also collected from adjacent areas to the southwest (Algoa Bay, n=22) and northeast (KwaZulu-Natal (KZN), n=20) of the Wild Coast to investigate similarities and differences between these areas. Despite a high degree of niche overlap between the two species (41%), common dolphins fed with a broader niche (standard ellipse area probability 0.89) than bottlenose dolphins in the summer and a narrower niche in the winter (probability 0.94). There was a clear spatial variation in the diet of bottlenose dolphins along the coast, with individuals from Algoa Bay and Amathole demonstrating 0% niche overlap with individuals from KZN, but the mechanism for these differences remains unclear as other species from South African waters demonstrate a strong southwest to northeast gradient in nitrogen for the Eastern Cape coastline. This research provides valuable baseline information regarding dolphins off the Wild Coast of South Africa, which remained largely unknown. My results indicate that bottlenose dolphins may be more resident in the Wild Coast than previous predicted, and confirm that common dolphins are highly mobile in this area.

- Description: The activity of fishing can be traced back to prehistoric times. However, only in the last century has there been a focus on the management of fisheries. Fishery regulations are tools used by resource managers with the aim of protecting the long-term sustainability of fishery resources. Although there is an overwhelming amount of evidence demonstrating the decline of fisheries, non-compliance with these regulations by fishers continues to manifest, which can exacerbate the negative ecological impacts of fisheries. Popular methods towards the measurement of noncompliance in fisheries derived from previous human dimensions literature may be flawed. Theories on improving compliance behaviour have typically relied on theory, which has at times proved paradoxical. Addressing the issues of non-compliance within a fishery of interest requires measuring the levels of non-compliance within the fishery and determining the relevant sociopsychological drivers behind the non-compliant behaviour. The data collection methods used during these assessments are limited in human dimensions research and are often case and context specific, requiring researchers to identify which approach is most practical for the specific fishery of interest. By identifying relevant behavioural drivers of non-compliance, a more effective approach aimed at improving compliance can be tailored. The recreational marine-based shore fishery (MBSF) in South Africa is not impervious to noncomplaint behaviour. In fact, it has been estimated to have relatively high rates of non-compliance. This high level of non-compliance makes the South African MBSF a unique and optimal context in which to undertake research that aims to formulate a framework towards compliance assessments and that develops a suitable approach for improving compliance rates. Using surveys to obtain compliance data can provide a range of details about violators, however they are susceptible to social desirability bias (SDB). Choosing the best method for controlling SDB required an assessment of existing methods for doing so. In this first part of the study, only fishers who were covertly observed breaking the rules were surveyed, using one of three methods for reducing SDB, to ground-truth the responses. Ground-truthing was done to determine which method would be most effective for a large-scale study within the same fishery. Of the methods used, which include the direct questioning method (DQM), the random response technique (RRT) and the ballot box method (BBM), all contained some level of SDB. However, the BBM provided a significantly higher level of response accuracy (79.6% ± 11.9) than the DQM (46.5% ± 14.9) and the RRT (44.3% ± 12.5). Random-stratified roving creel compliance surveys that employed the BBM were then undertaken at various locations along South Africa’s coastline to estimate current rates of non-compliance, and the face-to-face results were compared to results from an identical online survey to determine the suitability of online surveys as a replacement. The results indicated that online surveys only represent a subgroup of the fisher population within the MBSF, suggesting that face-to-face survey methods are required to obtain a more comprehensive sample and a more robust estimate of noncompliance. The results, based on 453 face-to-face surveys, showed a high level of overall self-reported noncompliance (48.3%) within the fishery. Responses to Likert scale survey questions on various aspects of the fishery, including angler motivations for fishing, were then modelled to test the relationship between the anglers’ responses and their compliance behaviour. In the South African MBSF context, the most significant behavioural drivers behind non-compliance related to normative concepts. Specifically, the poor perceptions of management and value-based legitimacy as well as low levels of moral obligation to adhere to the regulations appeared to contribute most to the observed non-compliant behaviour. Angler motivations for fishing also played a significant role in determining the compliance behaviour of anglers, with those fishing for food being more likely to violate regulations. In most countries, regardless of economic context, interventions to improve recreational fishery compliance have been developed around the instrumental concept. However, these findings suggest that for recreational fisheries, managers would do well to evaluate the impact of normative concepts on compliance and to design interventions aimed at addressing these. In the case of the South African MBSF, interventions that address angler perceptions of legitimacy and aim to correct misperceptions about social norms of compliance may provide a more practical and cost- effective method for improving poor compliance behaviour.

- Description: Mining is one of the most contentious water users. The mining sector has assumed that promises of economic growth and job creation will enable environmental concerns to be bypassed with as little interference as possible. More recently, the reality of legacy issues related to the inappropriate sign-off of mining sites has become increasingly clear, with acid mine drainage (AMD) being a prime example. There are also increasing concerns regarding uncontrolled prospecting. Climate change is one of the major issues faced in the 21st century, with predictions of heightened water stress for the Southern African region. This, coupled with increased population growth is putting a massive strain on the water resources currently available, making it vital to better protect and ensure the longevity of our water resources. The Carolina Crisis of 2012 highlighted the importance of protecting our water resources, and how easily they can be contaminated to a point where water is not usable. The Carolina crisis provided researchers with a suitable study site to better understand the role mining operations have in a catchment that has experienced a major pollution incident, and what changes have occurred since. In order to understand coal mining practice in relation to regulatory provisions, this project critically explored the processes involved within the mining sector, from ‘cradle-to-grave’, which is known as the coal mining life cycle. In addition, the composite suite of requirements of all the legislative provisions involved in the industry were investigated and the relationship between coal mining practice and environmental protection was explored. These elements were researched in the Upper Komati River Catchment specifically for catchment X11B, using Cultural Historical Activity Theory (CHAT), which gives a holistic understanding of mining as a human activity system. CHAT also sheds light on the issues, gaps and overlaps currently being experienced in the coal mining sector. The Thesis refers to case studies of where mining issues have caused environmental degradation. A complete mining lifecycle in terms of regulatory provisions was compiled, and major issues were uncovered with current legislation in the mining sector that can contribute to the degradation of water resources in South Africa. An integrated water resource quality management plan is needed in order to streamline conservation mandates, identify and reduce duplication of effort and specify roles and responsibilities of authorities involved with decision making process. A Decision Support System (DSS) has been proposed, which would involve adaptive, participatory and inclusive management.

- Description: Mining is one of the most contentious water users. The mining sector has assumed that promises of economic growth and job creation will enable environmental concerns to be bypassed with as little interference as possible. More recently, the reality of legacy issues related to the inappropriate sign-off of mining sites has become increasingly clear, with acid mine drainage (AMD) being a prime example. There are also increasing concerns regarding uncontrolled prospecting. Climate change is one of the major issues faced in the 21st century, with predictions of heightened water stress for the Southern African region. This, coupled with increased population growth is putting a massive strain on the water resources currently available, making it vital to better protect and ensure the longevity of our water resources. The Carolina Crisis of 2012 highlighted the importance of protecting our water resources, and how easily they can be contaminated to a point where water is not usable. The Carolina crisis provided researchers with a suitable study site to better understand the role mining operations have in a catchment that has experienced a major pollution incident, and what changes have occurred since. In order to understand coal mining practice in relation to regulatory provisions, this project critically explored the processes involved within the mining sector, from ‘cradle-to-grave’, which is known as the coal mining life cycle. In addition, the composite suite of requirements of all the legislative provisions involved in the industry were investigated and the relationship between coal mining practice and environmental protection was explored. These elements were researched in the Upper Komati River Catchment specifically for catchment X11B, using Cultural Historical Activity Theory (CHAT), which gives a holistic understanding of mining as a human activity system. CHAT also sheds light on the issues, gaps and overlaps currently being experienced in the coal mining sector. The Thesis refers to case studies of where mining issues have caused environmental degradation. A complete mining lifecycle in terms of regulatory provisions was compiled, and major issues were uncovered with current legislation in the mining sector that can contribute to the degradation of water resources in South Africa. An integrated water resource quality management plan is needed in order to streamline conservation mandates, identify and reduce duplication of effort and specify roles and responsibilities of authorities involved with decision making process. A Decision Support System (DSS) has been proposed, which would involve adaptive, participatory and inclusive management.

- Description: The Namibian education system has undergone major policy shifts from a ‘top-down’ hierarchical leadership practice to a more shared and democratic form of leadership in schools. These policies compel principals and school management team members to involve level-one teachers in decision-making and other leadership roles within their schools and beyond. However, to this end, the goals envisaged by policies for teachers to participate in, and contribute to the overall school leadership activities and decision-making have not been fully realised. This was due to the inherent hierarchy of the ‘top-down’ system and autocratic leadership style which remains powerful within the current school practice. Against this backdrop, this study interrogated how teacher leadership can be developed in a rural Secondary School in northern Namibia. The underlying cultural-historical conditions that promoted or constrained teacher leadership development were surfaced. Opportunities for changes in leadership practices through a formative intervention were developed. Cultural Historical Activity Theory (CHAT) was utilised as a theoretical and analytical framework in this study together with Grant’s Model of Teacher Leadership (2006; 2008; 2010). Five level-one teachers, two school management members and a school board chairperson were selected as research participants by means of a purposive sampling method. Furthermore, the study used document analysis, semi-structured interviews, questionnaires and change laboratory workshops as main tools for data generation. The findings revealed that participants understood the concept of teacher leadership differently and that teachers in the case study school were leading in all four zones of teacher leadership model (Grant, 2006; 2008; 2012) although their roles differed. However, the study also found that teacher leadership development was mostly intensified by managerial structures. It appeared from the findings of this study that conditions such as the role of the school management team (SMT) members in promoting teacher leadership development, a supportive organisational culture, and provision of learning support amongst staff members through the attendance of workshops emerged as factors promoting the development of teachers as leaders. The study also revealed that there were many cultural and historical tensions that constrained the practice of teacher leadership development in school. Thus, the study argues that limited leadership training and an inherent ‘top-down’ hierarchical style of leadership was the main underlying systemic causes that constrained teachers to be developed as leaders. Through the change laboratory workshops, the findings suggested that there was a need for continuous professional development initiatives and leadership training, as alternative way for the realisation of teacher leadership development. Finally, a recommendation that leadership aspects should be constituted in pre-and in-service professional development training as an ongoing practice is made.

- Description: As an academic and applied discipline, sport psychology is interested in identifying, understanding, measuring and developing the various mental constructs that interact with physical factors, aiming to produce optimum performance and enhance athletes’ experience of sport participation. The programmes developed within sport psychology are not only applicable to sport, but have applicability within other areas, such as the performing arts, business and professions that are considered high risk, such as the military. Using a mixed methods approach and a triangulation of qualitative and quantitative data collection and analysis techniques, the goal of this research was to document the process of developing and implementing a psychoeducational mental toughness programme and to evaluate the programme through exploring the participant’s subjective experience of such a programme. The aim of the research was to contribute to the existing literature on mental toughness programmes. This was attained through administering the Sport Mental Toughness Questionnaire (SMTQ) and a semi-structured interview, which informed the development and implementation of a psychoeducational mental toughness programme relative to the idiosyncrasies of the participant and grounded in strengths-based approaches to mental toughness development. Results were obtained based on post-implementation data collected through a second administration of the SMTQ and a semi-structured interview. The participant experienced the programme as positive and results were indicative of changes in his experiences of self-confidence and control, related to the global themes of mindset, flexibility and mindfulness.

- Description: The primary research objective considered by this study was to determine the nature of the governance system employed by the Offerman Family businesses in ensuring that all company assets, resources and actions are directed at, and controlled in the achievement of established company objectives and are accounted for to all legitimate stakeholders. Four related secondary objectives were also examined. The Offerman Family businesses consist of three separate companies that all make clay bricks in some form. Over recent years, the Offerman Family businesses have grown and taken on various minority shareholders in these three separate companies. For this reason, the governance requirements of the businesses have changed significantly from when the businesses were smaller and owned by a single family. The literature review on which the study is founded commences with an overview of family business topics appropriate to the research. Following this introduction, the history of the Offerman Family businesses is presented through until the present day (August 2010). Topics of governance are then considered in depth with a particular focus maintained throughout on that most applicable to the Offerman Family businesses. The research followed a case study approach within the phenomenological research paradigm. The details of the methodology employed are provided including an explanation of the questionnaire used as the research instrument. The questionnaire was submitted to ten people capable of influencing governance in the Offerman Family businesses and a useful response rate of 90 percent was achieved. The findings of the research detail the nature of the governance system employed by the Offerman Family businesses. It appears that there are shortcomings with family governance while governance of the businesses seems to be facilitated by the presence of the requisite governance building blocks such as a board of directors. Nevertheless, these governance systems are currently not functioning optimally leaving considerable room for improvement. The study closes with a review of the secondary research objectives and the resolution thereof. A list of recommendations is provided, which if implemented, could assist the Offerman Family businesses towards improving governance. Recommendations towards additional research are offered followed by an explanation of the limitations of the study.

- Description: [Preface - Nico Jooste]: For more than ten years, we have been involved in implementing internationalisation of South African Higher Education. The we I am referring too, are those who are both visionaries and passionately dedicated to the process of internationalisation. A small group of South African Higher Education administrators, academics and senior managers involved themselves in the process of internationalisation of their institutions, and collectively the South African system. This process of internationalisation started as an uncoordinated response to the demands of a South African higher education system that was determined to break with the past, and re-connect with global higher education, it was left to a few dedicated visionaries to create the support structure that would not only assist the higher education institutions, but also the system. The other bodies that were supposed to pay attention to this very important aspect of Higher Education in the 21st century were too busy with other, equally important, matters. It became clear that the priorities of organisations like SAUVCA were not internationalisation, and IEASA was established as the vehicle to promote it. This story of IEASA needed to be told. This book is not aimed at IEASA members only, but also at the broader higher education public. This is the story of an organisation that touched all parts of South African Higher Education society as well as the broader society. It is partly the ‘corporate memory’ of Internationalisation, as well as a reflection on achievements. Ten years looked like a short period to reflect on an organisations history, I am however of the opinion that in a society that is changing so rapidly, we need to reflect more frequently on the past so that we can plan a better future. For any historian operating in the modem era of electronic communication, access to sources of information has become a major challenge. IEASA, Thilor Manikam in particular, needs to be commended for the accurate record keeping of events over the past ten years. Kirstin Nussgruber very diligently captured the efforts of the forces driving the establishment of IEASA for the first two years. This book was mainly based on evidence gathered from minutes, reports and letters that are in the possession of the IEASA Office. I also had the privilege, and advantage, to be a member of the Executive Committee for the past five years. This book cannot be the last word on IEASA, as it is only the view of a member. The bias is thus toward IEASA and focusses mainly on its achievements. Chapter 3 focusses mainly on the achievements of a voluntary organisation. The efforts over the ten years of three persons namely. Roshen Kishun as President, Derek Swemmer as Treasurer, and Thilor Manikam as the Administrator stood out, and was the stabilising factor during the foundation years. The role of Roshen Kishun in the publication of Study South African cannot be underestimated. Without his vision, drive and effort, this publication would not be preparing for the launch of the seventh edition. It is a unique source of information about South African Higher Education. Very few other systems, if any. produce such a publication. Although the author was requested by the IEASA Executive Committee to write this book, the views expressed in this publication is not the views of the Executive Committee, but that of the author.

- Description: In the current business climate, performance is increasingly determined by how flexibly and effectively companies can utilize their human resources and this in tum, is influenced by employee morale. Morale refers to a state of psychosomatic health marked by an energetic, decisive resolution to achieve a given goal. When morale is low, employees may do what is required but do not have the energy to 'go the extra mile'. The importance of maintaining high morale is thus evident. The following project involved a study of morale in Cadbury's Port Elizabeth plant. Cadbury management was concerned about low morale following a recent merger with Bromor Foods. They thus wanted to assess: the state of current morale; any factors that may be influencing it; indicators of low morale (so that it may be monitored in the future) and finally, ways of addressing any existing morale issues. In order to achieve these aims, the researcher conducted interviews with various people to explore morale issues from employees' perspectives. She then sought confirmation for these views at the organizational level through the use of a survey. Statistical and thematic analyses showed morale to be low for middle managers and revealed a variety of indicators and influencing factors, as well as suggestions for addressing them. Despite the need to boost the sample size with convenience sampling, and thus, reduced representivity, the research was successful in answering the research aims.

- Description: During this research an attempt was made to gain an understanding of the experiences and needs of the social workers acting as intermediaries for the sexually abused children in the criminal court during the trials of perpetrators. To achieve this, ten social workers that have performed the role of intermediary were interviewed. Research as well as literature on this topic is limited and it is believed that this study will present a valuable basis to pursue in further research as well as assist social workers already rendering intermediary services. Literature that was available was found to be critical of the adversarial system and the negative elements associated with the system, especially for the child witness. The study found that there are many problems associated with the intermediary system. The most important issue is the delay between the decision to prosecute and the trial as this impacts negatively on the child witness. In addition social workers acting as intermediaries are inadequately trained and are not supervised in this role. As a result very few are willing to continue with the procedure. Nevertheless the intermediary system is adjudged better than the adversarial system, especially as the child witness no longer has to face the alleged perpetrator in an open court. The thesis ends with recommendations for addressing the concerns of intermediaries in order to strengthen the system.

- Description: This thesis is a study of themes and genre in Tennyson's Idylls of the King. I have not attempted to present a survey of the body of critisicm on the cycle, nor have I attempted a comprehensive comparison of the poem with any of Tennyson's sources. The first chapter is based on A. Fowler's study of genres and I follow the implications of his work in my reading of the Idylls. Tennyson blends various generic strands in his cycle, in particular allegory, epic, dramatic monologue and the Alexandrian idyll, to create a complex psychological allegory of epic scope which both draws on traditional genres and extends them. I believe the Idylls should be read as a cycle and in the order in which Tennyson finally presented them; the ordering process is as much part of the creative process as the actual act of composition. I have adopted Priestley's sensible division of the twelve poems which he says "falls naturally into three groups of four, corresponding closely to the three acts of modern drama" (1960, p.252-254)" The second chapter begins the sequential examination of the first four "spring" and "summer" poems beginning with the symbolic The Coming of Arthur. This idyll begins Tennyson's Arthurian mythopoeia, creating a poetic kingdom of the mind. The "act" closes with the Geraint and Enid idylls, all four works in this section ending happily. The third chapter deals with the idylls which plot the corrupting and ever-widening influence of the adulterous relationship of Lancelot and Guinevere, one cause of the destruction of the institution of the Round Table. Other causes of the demise of Arthur's order are the pernicious influences of the evil Vivien and Modred and the meaningless and sterile spirituality that prompts the quest of The Holy Grail. The last four idylls chart the final collapse of Arthur's realm, the utter disillusionment of individual idealism - personified by Pelleas, an anachronistic spring figure who appears in Camelot's bleak and hostile winter - and the complete social decay which is demonstrated by the fiasco of The Last Tournament. The tragic denouement of the cycle, on both individual and social levels, is evident in Guinevere, in which Arthur's wretched and traitorous queen understands Arthur's vision, but too late to save Camelot from ruin. In the final framing idyll, The Passing of Arthur, Tennyson's myth is elevated to the level of universal significance, the Idylls of the King becoming "not the history of one man or one generation but of a whole cycle of generations" (Memoir, ii, p.127).

- Description: This thesis is a study of themes and genre in Tennyson's Idylls of the King. I have not attempted to present a survey of the body of critisicm on the cycle, nor have I attempted a comprehensive comparison of the poem with any of Tennyson's sources. The first chapter is based on A. Fowler's study of genres and I follow the implications of his work in my reading of the Idylls. Tennyson blends various generic strands in his cycle, in particular allegory, epic, dramatic monologue and the Alexandrian idyll, to create a complex psychological allegory of epic scope which both draws on traditional genres and extends them. I believe the Idylls should be read as a cycle and in the order in which Tennyson finally presented them; the ordering process is as much part of the creative process as the actual act of composition. I have adopted Priestley's sensible division of the twelve poems which he says "falls naturally into three groups of four, corresponding closely to the three acts of modern drama" (1960, p.252-254)" The second chapter begins the sequential examination of the first four "spring" and "summer" poems beginning with the symbolic The Coming of Arthur. This idyll begins Tennyson's Arthurian mythopoeia, creating a poetic kingdom of the mind. The "act" closes with the Geraint and Enid idylls, all four works in this section ending happily.

The presented case study aims to demonstrate the efficacy of psychotherapy with a child previously treated with medication
- Authors: Cheesman, C

- Description: The impetus for using the therapy with J.B. for this study was primarily the challenge inherent in the situation from the moment the parents and J.B. arrived for their family interview and assessment. They had been through many professionals by then, and much medication. They were sceptical of our intervention, since nothing to date had relieved the situation, and J.B. still had outbursts of rage towards his mother, he was still expressing suicidal ideation and anxiety. The challenge was particularly in relation to the mother, who had great difficulty conceptualising J.B. 's problems as being emotional and relational in nature - she was infinitely more comfortable with physiological interpretations of everything. This had the effect on the therapist and the supervisor of frequently reassuring their belief in psychotherapy as the treatment of choice in this case, or if in fact there was a lurking 'disease ' or organic cause to the child's behaviour. The pressure was thus considerable in this respect, despite the fact that the child had been examined physically and nothing found. This study aims to demonstrate the efficacy of psychotherapy, and the changes that took place, with this patient who was previously treated with medication.
