  • Description: A study was conducted on the self-reported symptoms of Mild Traumatic Brain Injury sustained in Rugby Union at the pre- and post-season stages. A full sample of 30 rugby players at Rhodes University was compared to 27 non-contact sport controls. A reduced sample of 20 rugby players and 9 control participants provided improved control for education and IQ and was compared. Measures included the WAIS-III Vocabulary and Picture Completion Sub-tests to estimate IQ level, the symptom checklist on a widely used computer-based program (ImPACT), and a paper and pencil self-report 31-Item Post-Concussion Symptom Questionnaire. Independent and Dependent T-Test comparisons were conducted on the full and reduced samples. The symptoms reported by the rugby group appeared to be more pronounced on both the ImPACT Symptom Scale and the 31-Item Post-Concussion Symptom Questionnaire when compared to the control group at both the pre-and post-season stages. It was concluded that the rugby players demonstrated evidence to support the hypothesis of having sustained more previous concussions and reporting more symptoms at the pre-season stage when compared to comtrol participants. No prevalent changes for either the rugby or control groups were seen in dependent comparisons from pre-to post-season.

"Symbiosis or death" an ecocritical examination of Douglas Livingstone's poetry

  • Description: As the quotation in the title of this thesis indicates, Douglas Livingstone states that unless humankind can learn to live in mutuality with the rest of the natural world, the human race faces extinction. Using the relatively new critical approach of ecological literary criticism (ecocriticism) this thesis explores Livingstone's preoccupation with "symbiosis or death" and shows that the predominant theme in his ecologically-orientated poetry is one of ecological despair. Countering this is a tentative thread of hope. Possible resolution lies in the human capacity to attain compassion and wisdom through the judicious use of science, creativity, the power of art and the power of love. Livingstone's ecological preoccupation is thus informed by the universal themes which have pervaded literature since its recorded beginnings. The first chapter examines the concepts of ecology and literary ecocriticism, followed by a chapter on the life and work of Douglas Livingstone, and a review of the critical response to the five collections of poetry which predate A Littoral Zone, his final work. The remaining four chapters offer an analysis of his ecologically-orientated poetry, with the majority of the space given to an examination of A Littoral Zone. The following ecological themes are used in the analysis of the poems: evolutionary theory, humankind's relationship to nature, ecological equilibrium, and ecological destruction. The latter two themes are shown to represent Livingstone's view of the ideal and the real, or the opposites of hope and despair. The analysis interweaves an argument with the existing critical response to this collection. This thesis demonstrates that Livingstone's crucial message – the need for humankind to attain ecological sensibility or “the knowledge of right living” (Ellen Swallow) and so obviate its certain extinction – has largely been ignored in previous critical works.

  • Description: Neuropsychological testing is recognised as one of the cornerstones of concussion evaluation, contributing significantly to both an understanding of the injury as well as management of the recovery process. Despite the high incidence of concussion at school level, traditional paper-and-pencil neuropsychological testing has generally been absent from school concussion management programmes, largely due to time and cost constraints. Now, the recent development of computerised neuropsychological testing is providing the opportunity for including neurocognitive assessment in this process. The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a valid and reliable instrument of this type and normed on 13 - 18 year old North American high school athletes, as well as adult groups. The current recommendation is that athletes are baselined preseason in order to provide an individualised comparative level against which to monitor recovery and provide return-to-play recommendations. This in itself is quite a cumbersome process, thus the present study set out to ascertain whether baseline testing of all athletes is necessary, or whether the use of US or SA normative data alone would provide an appropriate standard against which to interpret the postinjury scores. From a leading South African rugby playing school, the 1st and 2nd rugby teams, (16 - 18 years) were baselined using ImPACT. Three athletes, who were subsequently referred with concussion during the rugby season, were followed up with serial testing on ImPACT. An analysis of the follow up scores was conducted to chart the athletes' recovery process, in relation to the athletes own baseline scores (using US and SA reliable change indices) and age appropriate US and SA normative ranges. The relative utility of individual baselines scores versus these normative ranges was then critically evaluated. It was concluded that a combination of both baseline and normative data provided optimal management of the athlete, with the methods complementing each other in the interpretation of post-injury results. Overall, the SA normative ranges seemed to provide slightly better management guidelines than the US normative ranges when used with this sample of South African high school athletes.

  • Description: South Africa's education management system has undergone a long history of transformation from the promulgation of the Bantu Education Act of 1953 to the realisation of democracy, and in this context, the South Mrican Schools Act (SASA) of l996. Apartheid legislation and the new democratic legislation have had a profound impact on the education leadership and management of schools, in which authoritarian management practices have been replaced by democratic management practices. However, democratic management practices have not yet had a significant effect in the leadership and management of schools, especially in the schools of previously disadvantaged areas. This thesis seeks to examine perceptions held by education stakeholders in the light of the rights of students as stipulated in the discipline provisions of the Schools Act of 1996, in one of the rural high schools in the Northern Region of the Eastern Cape Province. One of the most important discipline provisions is the ban on corporal punishment in schools. My intention in carrying out this research was not to generalise my findings but to understand the experiences and perceptions of the stakeholders in this school regarding the discipline provisions of the SASA. The data suggest that authoritarian education practices, especially corporal punishment, are still a factor in the maintenance of student discipline in this rural school. Stakeholders still believe in the use of corporal punishment as the only way of maintaining discipline and an orderly environment for teaching and learning. Such beliefs, assumptions and values concerning the use of corporal punishment are held by the principal, teachers, students and parents and have not changed since 1996. Beliefs, assumptions and values on the exclusive use of power by the principal on issues of suspension and expulsion are still being held by the above stakeholders in the school. The vision of the SASA that schools become autonomous institutions with democratic leadership and management practices does not seem to be practical because of the centralisation of power in the hands of the Provincial Head of the Education Department. This centralisation of power denies the principal and other stakeholders of the school the power to decide on crucial matters like the expulsion of misbehaving students, because it is the provincial Head who decides on the seriousness of offences committed by misbehaving students and subsequent expulsions. Apart from the location of power in the Provincial Head of the Education Department, the stakeholders of this school are also powerless on expulsion of students, or any other form of punishment because of the implication of the "right" to education in the Bill of Rights in the Constitution of the Republic of South Africa. The education department has to devise programmes that change the beliefs and assumptions of stakeholders on corporal punishment and decision-making on expulsions and suspensions. Unfortunately corporal punishment persists because parents use it in the home and support its use in school. Programmes on alternatives to corporal punishment are required for the smooth implementation of the SASA.

  • Description: The citrus industry is one of South Africa's largest agricultural sectors in terms of export earnings with lemon fruits and juice as a trendsetter due to their high grade quality. According to growers, the Eastern Cape Province of South Africa alone produces an excess of about 10-14,000 tons of lemon juice which is presently of no economic value due to the sour taste and “bitterness”. As a result of this excess and in order to make use of the polyprotic acids naturally occurring in the lemon juice, four fertilizer nutrient mixtures are formulated, using lemon juice as base. From a conceptual scientific approach, characterization (physico-chemical and functional properties determinations) of Eureka Lemon fruit juices were undertaken, followed by smaller scale batch formulation experiments. On the basis that these lemon juice-based fertilizer mixtures are prepared following standard liquid fertilizer formulation guidelines, a field test was conducted to evaluate their potential effectiveness to influence plant growth. A growth chamber testing on tomato plants revealed high growth response (> 99.9 % certainty) potential in two of the semi-organic mixtures formulated while the organic mixture showed a relatively good growth rate as compared to the control (pure tap water). According to statistical analysis (ANOVA) comparison, two of the semi-organic mixtures performed considerably better than the two commercial samples evaluated. Potential benefits profoundly associated with these nutrient mixtures as compared to similar liquid fertilizer products on the market is that most nutrients are chelated and dissolved in solution. Also, the mixtures contain all necessary nutrients including plant growth substances required for healthier plant growth. The most important socioeconomic impact is the value addition to the technology chain in the citrus industry. The use of fluid fertilizers in significant quantities is less than twenty years old. Nevertheless, growth has been so rapid that in South Africa demand for mixed liquid fertilizer has greatly increased from 90 000 tons NPK & blended micronutrients in 1955 to more than 600 000 per annum tons today (Report 41/2003, Department of Minerals and Energy). The liquid fertilizers market is sparsely specialized with major competitors like Omnia, Kynoch and Foskor supplying more than 50 % of the market demand. Amongst the nutrient mixtures formulated, mixture one is an NPK (1-1-2) based nutrient mixture containing both secondary nutrients (0.5 % Mg & 1.0 % Ca) and seven micronutrients (0.1 % Fe, 0.05 % Cu, 0.05 % Zn, 0.05 % Mn, 0.02 % B, 0.0005 % Mo and 0.0005 % Co). The composition of this mixture offers the formula a potential to be used as a general purpose (all stages of plant growth) fertilization mixture in view of its balanced composition (containing all essential plant nutrients). Mixture two contains essentially the micronutrients and in higher concentrations (0.3 % Fe, 0.3 % Cu, 0.1 % Zn, 0.2 % Mn, 0.02 % B, 0.0005 % Mo and 0.0005 % Co) as compared to mixture one except for boron, molybdenum and cobalt. The concentration of the micronutrients contained in this mixture is adequately high which offers a potential for it to be used in supplementing nutrition in plants with critical micronutrient-deficient symptoms. Mixture three is very similar to mixture two (1.0 % Fe, 0.05 % Cu, 0.05 % Zn, 0.05 Mn, 0.05 % B, 0.0005 % Mo and 0.0005 % Co) except that the concentrations of all seven micronutrients are considerably less than those of contained in mixture two. However, the concentration of iron in this mixture is as high as 1.0 %. The mixture has a potential to be used in high iron-deficient situations. Mixture four is an organic formula with relatively low nutrient concentrations (NPK-0.02-0.02-1, 0.27 % Mg, 0.02 % Ca, 0.008 % Fe, 0.26 % Cu, 0.012 % Zn, 0.009 % Mn). Nevertheless, this mixture is appealing for organically grown crops where the use of chemicals is prohibited by standards. These lemon juice-based nutrient mixtures were further characterized and tested for stability and storability over a period of eight weeks. This study revealed no major change in the physical quality (colour, pH and “salt out” effect). The basic formulation methodology is a two-step procedure that involves filtration of the lemon juice to remove membranous materials, mixing at ambient temperature and stabilization of the nutrient mixtures. However, for the organic nutrient formula mix, filtration follows after extraction of nutrients from plant materials using the lemon juice.

  • Description: Members of the zinc binuclear cluster family are important fungal transcriptional regulators sharing a common DNA binding domain. Da181p is a pleotropic zinc binuclear cluster protein involved in the induction of the UGA genes required for the γ-aminobutyrate nitrogen catabolic pathway in Saccharomyces cerevisiae. The zinc binuclear cluster domain is indispensable for function in Da181p and little is known about other domains in this protein. The aim of the study was to explore the zinc binuclear cluster protein family using comparative bioinformatics as a complement to biochemical and structural approaches. A database of all zinc binuclear cluster proteins was composed. A total of 118 zinc binuclear proteins are reported in this work. Thirty nine previously unidentified zinc binuclear cluster proteins were found. Four homologues of Da181p were identified by homology searching. Important sequence motifs were identified in the aligned sequences of Da181p and its homologues. The coiled coil motif found in the Ga14p zinc binuclear cluster protein could not be identified in Da181p and its homologues. This suggested that Da181p did not dimerise through this structural motif as other zinc binuclear cluster proteins. Solvent accessible site that could be phosphorylated by protein kinase C or casein kinase II and the role of such sites in the possible regulation of Da181p function were discussed.

  • Description: Recently, organisations have been faced with challenges like never before. Increasing competition from businesses across the world has meant that businesses must be more careful about the choice of strategies to remain competitive. This situation has placed more focus on organizational effectiveness in that systems and processes be applied in the right way to the right things to achieve results. All of the organisational processes must continue to be aligned to achieve the overall results desired by the organisation for it to survive and thrive. Performance management is an ongoing process that should reflect the current and emerging business challenges, as well as the company’s values about performance and careers. As the business and workforce change, the performance management process should be modified to ensure that the process and tools remain congruent with organisational values and priorities. The objective of this study was to identify the influence of the current performance management system, in the Finance department at General Motors South Africa, as a facilitation tool in aiding or assisting management in achieving individual and departmental goals. To achieve this objective a comprehensive literature study was performed to determine the views on performance, and on performance management systems. A questionnaire was designed based on the guidelines in the literature study, in order to establish the extent to which the organisation manages performance. The researcher used the random sampling method of selection and distributed the questionnaire to eighty one potential respondents via mail and electronic e-mail. Forty one completed questionnaires were returned and these were processed and -iiianalysed using Microsoft Office Excel 2003, running on the Windows XP suite of computer packages. The respondent’s opinion obtained from the questionnaires were compared with the guidelines provided by the literature study in order to identify shortcomings of the influence that the performance management system has on the achievement of individual and departmental goals at the selected organisation. It can be concluded from the respondent’s opinions that the greatest shortcomings of the current performance management system are the link between performance and reward, and commitment to the process in its totality. The other areas of concern are the lack of training and development, and the necessary resources required to achieve objectives. The study also indicates there is no overwhelming agreement that feedback, both positive and negative, takes place as the literature suggests. The following were the main recommendations and conclusions made: • Firstly, it is imperative that management undergoes training in the feedback and review process which is a critical element in the performance management cycle. • Secondly, to realise the benefit of increased employee effectiveness, management should undergo training to become more effective career coaches to promote a climate of continuous learning and professional growth. • Thirdly, the reward system should be reviewed, if management is committed to using pay as an incentive for desired levels and directions of performance. • Fourthly, management can set an example and build commitment for effective performance management and be leaders at all levels.

  • Description: The outsourcing market for information technology services has been transformed over the last few years. Outsourcing, once inspired primarily by cost reductions, now forms part of overall company strategies in order to improve focus. Intent: The purpose of this research project is to conduct a critical analysis of the outsourcing of information technology infrastructure. In particular, this paper will focus on the process followed and on adherence to good corporate governance and business ethics. This dissertation addresses (i) the strategic reasons for outsourcing, (ii) reasons for not outsourcing, (iii) the different types of models available, (iv) the outsourcing process to follow, and (v) the risks associated with outsourcing. These five aspects were all empirically tested in Trans Hex. Findings: The main findings were that (i) no recognized formal process had been followed; (ii) the risk profile of the outsourcing company changed and (iii) a post-outsourcing review is required to determine whether the process is working as planned and to identify opportunities for improvement. Conclusion: A new approach is needed to improve the viability and success of outsourcing information technology infrastructure. Based on the present findings it is argued that a holistic approach to information technology infrastructure outsourcing should be adopted which combines several outsourcing processes into a company-specific outsourcing process framework.

  • Description: This research is born out of recognition of the challenges Black Economic Empowerment (BEE) in the private sector faces in South Africa, with preferential procurement being one of the components of South Africa's Broad Based Black Economic Empowerment Strategy. Over the past years, South Africa has witnessed the birth of a new economy, one that allows for investment in its people, makes provision for sustainable growth through skills transfer and development, and ensures economic empowerment. The focus of this research is the Preferential Procurement strategy implemented at DaimlerChrysler South Africa (DCSA) as part of its overall Black Economic Empowerment strategy, the perceptions and expectations of how the current BEE preferential procurement strategy should work versus the perceived performance of how it is working. An official definition of Black Economic Empowerment is presented in the study, followed by barriers to growth of BEE suppliers. The aim of defining Black Economic Empowerment is to provide a good reference point against which an organization like DaimlerChrysler can assess the implementation of its preferential procurement programmes. Having discussed the above, there will be a reflection on government scorecard and a brief discussion of the two charters namely, mining and financial services charter. The study also presents the following requirements for a successful BEE corporate strategy: Strategic intent; External Balanced Scorecard; Financial Assistance; Skills development; Communication. A research methodology for conducting this study and data analysis is presented, followed by limitations of the study and recommendations for further research. It is expected that the knowledge gained from this study will help to I. Demonstrate the need to change perceptions and behaviour regarding Black Economic Empowerment. 2. Assist procurement officials to include BEE objectives into their procurement strategy. 3. Identify policy implications and assist in improving DCSA's Black Economic Empowerment Procurement strategy.

  • Description: It's almost like a dinner party and a buffet. A dinner party you get dished up stuff and you eat it and a buffet you can choose what you want out of a range of stuff. I mean think about it when you go to a dinner party- they always dish up something you don't like and you don't want to eat it anyway. It's the same if you have a lecturer in the front that just dishes out what you're going to learn, ... you have to learn it. But in terms of the curriculum negotiation process, I've got to choose what I wanted to leam. (Melissa II 27/11/01: 3) This thesis focuses on the process of negotiating the curriculum with twelve pre-service teachers registered for the Bachelor of Education (Primary) Degree during their Mathematics Education Course in their third year of study. The research is presented methodologically as an action research located within two paradigmatic positions, interpretive and critical. The research attempted to understand, interpret and critique the process of curriculum negotiation within the context of teacher education in South Africa In order to understand the negotiated curriculum process, experiences of the participants are presented through the use of their voices within the thesis. The interpretation is based on the construction and reconstruction of meaning during the enactment of the negotiated curriculum process and during the writing and reviewing of this thesis. The critique is rooted in the historical, cultural and social contexts of both the students and the author. The main contention of this thesis is that curriculum negotiation is not necessarily a suitable vehicle for developing a critical pedagogy in pre-service teacher education when all the participants form a homogenous group in this case, white middle-class women. The democratic values promoted within the context of our curriculum negotiation were fraught with dilemmas and entrenched the values of western liberalism. At most, the curriculum negotiation process and the development of a democratic learning environment, promoted a conscientisation at an individual level, namely a ' transformation of consciousness' . The democratic values promoted in our pedagogy were not sufficient in bringing about social change, a 'transformation for social action'.

A critical investigation of the relevance of theories of feminist jurisprudence to African women in South Africa

  • Description: Feminist theories emerged out of the revolutionary enthusiasm that swept the Western world during the late eighteenth and nineteenth century Europe. Based on the assumption that all persons have "inalienable or natural" rights upon which governments may not intrude, feminists in Europe and America advocated that equal rights should be extended to women who up to this point were not considered legal beings separate and deserving of these rights. Most African writers and feminists have argued that since most of the theories of feminist jurisprudence have their roots in this Euro-centric context, they cannot be applicable to African women and should therefore be discarded. The thesis acknowledges that to a certain extent their assertions are true. For years feminist jurisprudence has been restricted to an academic engagement with the law failing to take into account the practices and customs of different communities. It has largely been the realm of the middle class bourgeois white female and therefore has been inaccessible to the African woman. The thesis aims, however, to prove that these theories of feminist jurisprudence although Euro-centric have a place in the understanding and advancement of African women's rights in South Africa. In Chapter One the writer traces the history of South African women's rights and the laws that affect African women. Chapter Two presents the emergence of feminist theories and categories of feminism. The writer then seeks to identify the misunderstandings and tensions that exist between the two. The narrow conception of Euro-centric feminism has been that its sole purpose has been the eradication of gender discrimination, however, for African women in South Africa they have had to deal with a multiplicity of oppressions that include but are not restricted to gender, race, economic and social disempowerment. This is dealt with in Chapter Three. It is the opinion of the writer that despite these differences feminism does play a critical role in the advancement of women's rights in South Africa. Taking the South African governments commitment to the advancement of universal rights, the writer is of the opinion that African women can look to the example set by Western feminists, and broaden these theories to suit and be adaptable to the South African context. The answer is not to totally discard feminist theories but to extract commonalities that exist between African and European women, by so doing acknowledging that women's oppression is a global phenomenon. This is the focus of Chapter Four. To avoid making this work a mere academic endeavour, the writer in Chapter Five also aims, through interviews, to include the voices of African women and to indicate areas that still need attention from both the lawmakers and women's rights movements (Feminists). Finally, the writer aims to present a way forward, one that is not merely formal but also substantively attainable.

  • Description: This paper deals with an analysis of the discursive accounts of Eastern Cape white commercial farmers on the subject of Democracy. Drawing on the theoretical perspectives of Social Constructionism and Discourse Analysis – which view individuals’ accounts of their realities as produced and informed by their particular social and historical context – the paper seeks to provide an analysis of the content of, and rhetorical strategies within the participants’ accounts and explanations. Such accounts of the social, historical and political circumstances in which Eastern Cape commercial farmers find themselves are thought to provide valuable insights into the manner in which the process of democratisation has been received by members of the agricultural sector. Data collection was conducted via brief, audio taped, semi-structured interviews. The participants were all white men and women, living in a commercial farming region of the Eastern Cape Province. Responses to the interviews were subjected to the Discourse Analytical procedure advanced by Ian Parker. Analyses reveal that participants are critical of the notion of democracy; utilize specific rhetorical and argumentation strategies; make use of notions and techniques of ‘Othering’; and subscribe to a colonial / patriarchal ideology which attempts to idealize pre-democratic South Africa. These findings illustrate what is in many ways still an ongoing political and ideological struggle in the rural regions of the country.

  • Description: Riparian habitats in many parts of South Africa are severely degraded by invasive alien plants, especially trees. These invasions reduce water yields from catchments and affect riverine functioning and biodiversity. Initiatives are under way countrywide to clear alien plants from watercourses and surrounding catchments. Current understanding of key processes that regulate riparian functioning and define options for restoration is rudimentary. We review the impacts of riparian invasions and identify factors limiting the recovery of natural vegetation following alien clearance. We propose a framework of strategic interventions for optimizing restoration success. The framework identifies abiotic and biotic barriers to restoration at the scales of catchments and local reaches. In highly transformed catchments, interventions at the reach scale may fail if important barriers at the catchment scale are not addressed. The extent to which propagule supply and microsite conditions inhibit vegetation recovery is unknown. We also know little of the relative importance of dispersing vegetative propagules, dispersing seeds and soil-stored seed banks in vegetation dynamics, particularly after severe disturbances such as dense invasion by alien plants. The importance of geomorphological and hydrological factors in mediating recovery of riparian vegetation has not been adequately explored for all climatic areas in South Africa. More research is needed to determine the influence of different alien species and clearing treatments on the recovery of riparian vegetation. The literature strongly suggests that in highly alien-transformed catchments, the re-introduction of riparian species is required to promote recovery and suppress re-invasion. However, such interventions are unlikely to be widely implemented unless the cost: benefit ratios are favourable.

  • Description: The objective of this study is to investigate the reasons for international assignments ending in failure, using the current models of expatriates’ premature withdrawal decisions, so as develop solutions to those problems. Studies of expatriate failure and effects of expatriate satisfaction on organisational performance have been conducted but most of them in the overseas countries. These studies revealed that the practice of employing expatriates is a strategic move on the part of the multinational corporation to increase the international experience and knowledge base of present and future managers. Even though studies on strategies that companies can use have been done extensively, research still shows that a large number of overseas assignments end in failure. Failure being described as the premature return to the home country, not being able to adjust in the host company or country and immediately living the company upon return from the assignment. It is for this reason that in the researcher decided to investigate what could be the reasons that cause the expatriates to return home early. The research will be of importance to South Africa firstly, as organisations that are operating globally will copy the business systems and processes practiced in developed countries, and later bring knowledge, skills and expertise that will help in boosting the economy of the country. Secondly, the organisation's Human Resource Management will develop practices to ensure the successful and effective retention of expertise. Expatriate failure will be reduced and the process of repatriating expatriates will be meaningful. Individuals assigned will not find it difficult to adjust in the parent company, and later take the skills they have learnt to another company. Thirdly, managers generally will understand the challenges that accompany expatriation, and be able to meet those challenges. The research becomes an investigative research as one tries to establish if there is concurrence or deviation with the current models. A sample is drawn from a list of international companies that have operations overseas. The researcher has tried to get responses from companies in all provinces of South Africa so that the sample can be fully representative. The questionnaire is used as it is a common instrument for observing data beyond the physical reach of the researcher. The questions were selected to address each of the factors affecting decisions to withdraw from the country of assignment. Responses from the expatriates have helped to develop a new model that encompasses all the factors that cause the expatriates to leave the assignment early as well to develop solutions to the problems. This will not only help the multinational corporations to save on costs, but will also ensure that the company and the expatriate benefit from international assignment.

  • Description: Analysis of the flora of the Pondoland Centre of Endemism (PCE) recorded 2253 species in the combined checklist of four sites (Port St. Johns, Mkambati, Umtamvuna and Oribi Gorge). Of these 1 % species are endemic to Pondoland, representing 8.7% of the Species, 15% of the genera and 26% of the families of the combined flora. Forty-four percent ofthe combined flora was only recorded from one locality (between 17% and 26% of each flora) and only 12% of the flora was present in all four localities. Of the endemics only sixteen (8%) occurred in all four sites thus each site had its own complement of unique endemics and 21 % endemics were not recorded from any of the four sites. At species level the floras of Mkambati and Umtamvuna were the most similar, followed by that of Umtamvuna and Oribi Gorge. Port St Johns had the least in common with any of the othersites, but more in common with non-neighbours Umtamvuna and Oribi Gorge than with its nearest neighbour Mkambati. Mkambati and Umtamvuna had the largest proportion of PCE endemics and Port St Johns had the lowest. The four sites are quite similar at family level, sharing thirteen families in the top ten family list between them, but much less similar at generic level.

  • Description: With the increasing pressures and concerns in education regarding capability, lifelong learning, higher order cognitive skills, transdisciplinary education and so on, educators are seeking fresh ways to teach and new tools to support that teaching. In South Africa, Outcomes Based Education (OBE) has identified critical outcomes (skills) across all subject areas such as problem solving, teamwork, fostering critical thinking etc. as a way of responding to these pressures and concerns. But OBE has been criticised for lacking the necessary tools to develop these critical skills and to promote cross-discipline learning. One innovative way of offering transformative teaching, instruction and learning that may foster the development of these critical skills, particularly those concerned with critical thinking, is by using geographic information systems (GIS) technologies. The scope for using these technologies in secondary education is now being realised for teaching the more generic, cross-discipline skills described whereby students are learning not only about GIS but also with GIS. This realisation provides the opportunity to create flexible, computer-based learning materials that are rooted in authentic, real-world contexts, which aim to enhance the cognitive skills of the students. If these technologies can be used in an innovative way to develop critical outcomes and skills, a model needs to be defined to aid the design and development of learning materials using these technologies for use in schools. The primary aim of this study has been to develop such a model; a model which emphasises the development of real-world learning materials that develop higher-order thinking skills in learners. Another key product of this study is the submission of a comprehensive yet flexible framework for evaluating instructional design models found in the educational literature in order to determine if these design models can be used to develop learning materials forparticular contexts.

A hermeneutic description of a therapeutic interview using reader response concepts from literary theory

  • Description: Certain approaches in the discipline Psychology, use the term narrative to describe how they work. Upon investigation one finds that the term narrative is seldom informed from Literary Theory, the background from which it originated. Instead, other disciplines that were also influenced by Literary Theory are invariably used as a means of cross fertilisation, e.g. the work of Geertz from an anthropologist background. Therapists make use of techniques described in the theories in an attempt to come to an understanding of the interactions in the therapy session. Some of the later theories emanating from Literary Theory appear to very useful for opening new ways of research in psychology, especially because some of them already come from an interdisciplinary background. This research attempts to identify useful theories and then apply them within a hermeneutical background in a therapeutical session. Theoretical work on ambiguity, recent research on foregrounding and defamiliarization and also the research in psychonarratology appear to be eminently useful for coming to a deeper understanding of the processes that take place in a therapeutic environment. It is thought that these theories could be of use because they have been 'tested' against the experiences of real readers reading texts. As novels differ from reports and washing lists, therapeutic settings differ from discussions. A novel is a cultivated variant of a report, and a therapeutic conversation is a cultivated version of a chat. These theories then, were applied to a real therapeutic session. The therapists who participated were interviewed on the session and on their reactions to certain 'readings' made by them during the session. The purpose of the interview was to obtain an understanding of their interpretation of what had happened during that session. The questions, reactions, observations and reflections of the session constitute the text of this research. The generated text was then reread from the perspective of each of the theories. The data was collected and interpreted. The interpretation focusses on the therapists 'reading' or understanding of the session and in the process, leads the therapists and researcher to further levels of understanding. In conclusion, it was found that the theories were indeed useful as they were able to point out how certain stylistics of language and situation in the therapeutic session had led to hermeneutic or interpretive processes and also how these processes were perceived or experienced on reflection by the therapists.
