M.A. / This study is an attempt at providing substantiated research data on sensation seeking, measured using the Sensation Seeking Scale (SSS), and its role in sensory, perceptual and cognitive functioning. The areas of functioning investigated included sensory tolerance levels, preference for perceptual complexity, speed of perpetual closure, verbal ability versus spatial ability and creativity ...

D.Litt et Phil. / The departure point of this research is that the emergence of a system of intergovernmental relations will have direct and profound implications for the development of the country as a whole, as well as providing an additional dimension to the understanding of the approach to development in South Africa. A sound academic understanding of the nature of development in this country will therefore have no choice but to take into account the structures and processes which the major role-player (government) makes use of to facilitate and implement development ...

Family businesses make up a large number of businesses in South Africa, although they are not often researched. Many of these family businesses are SME (Small and Medium Enterprises), however they contribute substantially to the local economy, as well as job creation. Despite their extensive presence there is a very poor success rate of family businesses. One of the reasons for their low success rate could be the seemingly increased conservative nature of family businesses over time. Thus, a look into entrepreneurial processes, which promote adaptation, innovation and learning, may give family businesses a competitive advantage. An Abbreviated Grounded Theory approach was used to explore the presence, if any, of entrepreneurial processes within established family businesses in Grahamstown. Two generations of family owners as well as a non-family employee across four local businesses were interviewed. The results show that all four business show signs of entrepreneurship within their business, these include: risk taking, creativity, active competition, opportunity grasping and change. Previous generations within the business also showed signs of learning new technology, in turn the new generations learnt from the experience that their parents have had in the businesses. The results show that family businesses are capable of change, adaptation and learning, thus it may enable consultants and future researchers to strengthen family businesses across generations.

Occupational injuries and illnesses remain to be a heavy burden on workers and employees in industrial developing and industrially developed societies, and health and safety in workplaces continues to be an important issue for ergonomists. Steps are being taken to stimulate health and safety agendas and to discover ways in which health and safety in industries can be improved. The main responsibility of employers is to provide employees with information, instructions and training that they required to carry out their work tasks in a healthy, practical and safe manner. The role of education as a countermeasure to occupational injury and illness is being re-examined by health and safety practitioners and safety training is being considered as a vital part of accident prevention strategies. Effective training programmes should guarantee that workers possess the skills they require to complete their tasks in a safe and healthy manner. Very little is known about the type and quality of training workers undergo and how that training affects the safety outcomes of companies. There has been an attempt over the past 20 years to increase the research on safety communications and a great deal of this research has been focused on safety warnings; with the greatest attention been placed on the components of safety signs, such as colours, size, shapes and icons. The effects of these components on comprehension with relation to age and education have not received the same amount of attention. The impact of familiarity on safety warnings with respect to age and education has also received very little attention; despite the knowledge that familiarity has been shown to increase the noticing of warnings and the comprehension of safety information. Despite the increase in the research on safety communication, the literature and research in South Africa is scarce. Studies present in South Africa do not encompass the comprehension of safety signs or the ability of individuals with different age and education levels to learn the information included in the signs. Due to the multi-linguistic nature of South Africa and the fact that South Africa is an Industrially Developing Country (IDC) with high levels of illiteracy, issues such as the comprehension of safety information must be addressed. Therefore, the objectives of this study were to investigate the effects of safety sign attributes on learning and familiarity, in subjects that differed in age and education levels. These effects were investigated through measuring the reaction and response times of the different subject groups, as well as the number of components in the safety signs that were recalled correctly. The combined results of these responses were used as a measure for familiarity. A set of signs was designed for the study by the researcher using three different colours, three different shapes, three different icons and text. Certain variables were omitted from some signs to create the test pool and the eight conditions that were tested in a laboratory setting. Each condition contained different components of the designed signs and 60 subjects were used to test these conditions. The subjects were placed in groups according to their age and level of education. Subjects were required to learn a set of 64 signs, either “With Occlusion” or “Without Occlusion”, and asked to recall the meanings of the components in the signs. Reaction time, response time and error rate were measured from the responses. The results showed that the conditions resulted in different reaction times, response times and error rates for all subjects. The signs containing a combination of shapes and text resulted in the best performance. Age and education were found to have a significant effect on various performance criteria as did the method in which the signs were displayed (Occlusion and No Occlusion). The increased repetitions and sessions elicited lower reaction times, response times and error rates. The conclusions drawn from this study suggest that different attributes be considered carefully when subjects are expected to learn and recall information in safety signs. The results also highlighted the need to increase the exposure of individuals to safety signs in order to increase familiarity and ultimately improve the recall and comprehension of the attributes.

Due to their widespread and specious nature, small mammals are ideal for biogeographical studies. Small mammals also effectively connect various trophic levels by being both consumers and prey items for other animals. The Great Escarpment is the dominant mountain landscape in South Africa. Yet, very little small mammal research has been conducted on the Great Escarpment outside of the Main Drakensberg Mountains. This is surprising given the importance of mountains in shaping regional ecology. In this study, I assessed the diversity and community composition of small mammals at three high altitude (>1700m) sites within the Sneeuberg Mountain Complex (SMC) from June 2009 to May 2010. I also tested the effectiveness of five different bait types for measuring small mammal diversity (i.e. number of individuals caught, species richness, Shannon diversity index and Simpson index of diversity). Out of a total of 423 captures, 292 individuals of 12 small mammal species (one shrew, one elephant shrew and 10 rodents) were recorded over 5280 trap nights. The species richness and diversity of small mammals captured at the three sites were similar and this homogeneity was probably related to the regional processes (e.g. climate and latitude) that govern species richness and diversity. The most effective bait type in terms of capture success, species richness and diversity measurements was peanut butter and oats. In addition, the use of richness estimators revealed that peanut butter and oats was the most effective bait for sampling the species richness of small mammals. The effectiveness of peanut butter and oats was related to this bait having a more attractive scent, when compared to the other bait types. Future studies should focus on researching the range of local and regional processes that drive small mammal diversity at high altitudes in South Africa. I also recommend the use of more than one bait type when planning to survey small mammal communities.

Despite the acknowledged reality that HIV-related stigma is a major barrier to effective HIV prevention and treatment, and perhaps because it is complex in nature, few local empirical scales have been developed to measure stigma and to be able evaluate the impact of anti-stigma interventions. Whilst the development of two recent South African HIV-related stigma scales can be celebrated as a major breakthrough, the reliability and validity of these scales across contexts remains largely unknown. This research project employs these two local, and competing, HIV-related personal stigma scales - the first developed by Kalichman et al. (2005) and the second developed by Visser, Kershaw, Makin and Forsyth (2008)-to compare the psychometric properties of the scales and to obtain a measure of HIV-related stigma with a sample of 246 service staff employed at either Rhodes University Catering Division or the Hi-Tec Security company, both organisations located in Grahamstown, a small town in the Eastern Cape, South Africa. Both organisations are major employers of semi-skilled workers in this local context. The results suggest that the Visser et al. scale (2008) reports slightly better psychometric properties than the Kalichman et al. (2005) scale for this sample. Furthermore, the security guards appear to be more stigmatising than the caterers, and it is suggested that this might be a consequence of the combined influences of normative occupational roles and workplace context. Results also show that participants who practices safe sex, know someone with HIV and/or who have been tested for HIV show lower levels of HIV-related stigma. Finally, personal stigma scores are generally lower than attributed stigma scores, which might offer a useful point of intervention.

M.A. / The researcher has undertaken a social constructionist research project that aims to explore the narratives of therapists who work with HIV-positive clients in the South African context. The researcher hoped to generate information regarding the: difficulties or challenges that are peculiar to this type of therapy and the impact of this therapy on the professional and personal lives of the therapist. The initial part of the dissertation covers an investigation of the literature regarding HIV/AIDS and HIV-related therapy. This literature reveals that mental health workers and psychologists experience considerable stress and 'burn-out' related to the many difficult issues provoked by HIV-positive clients. The theoretical foundations of postmodernism and social constructionist research are also described. In line with the researcher's epistemology, the methodology was qualitative in nature and made use of unstructured interviews. The narratives of the participants were then subjected to a qualitative or thematic analysis. The results of the study are presented in terms of the significant themes in the participants' accounts. It is evident in the narratives of the research participants that there are peculiar difficulties in therapy with HIV-positive clients. Also evident are the significant effects that this work has on the therapists' professional and personal beliefs, attitudes, philosophies and behaviour. Finally the results are discussed and a critical evaluation of the study is offered. The objective of the research is not to generalise the findings to all Clinical Psychologists who work with HIV-positive clients. A recommendation based on the findings is that therapists considering working with HIV-positive clients familiarise themselves with the issues that this therapy raises.

M.A. / This study is born from the motivation to empower psychiatric social workers in South Africa with a classification system that compares well to classification systems used by other disciplines in the psychiatric setting. The classification system in question is the Person-in-Environment Classification System (PIE) and therefore this study sets out to investigate and report on the value the PIE might have for psychiatric social work in South Africa. Another objective then is to highlight what problems were experienced in using the PIE which will form the foundation for recommendations on further research and possible adaptations. The first part of this dissertation sets out the motivation and objectives of this study, where the second part gives a thorough description of psychiatric social work, the ecological approach in psychiatric social work, classification systems and the PIE itself. The research process is described whereafter the results of the data are explained. The results are discussed within the framework of three evaluative factors, namely image, applicability and structure which gives an indication of the value the PIE has for psychiatric social work. The conclusion can be drawn from this study that the PIE has definite value in all three evaluative factors. It can be concluded that the PIE can serve as an empowering tool in establishing and defining psychiatric social work's unique contribution to South African psychiatry.

M.A. / The purpose of the study was to ascertain whether patients suffering from irritable bowel syndrome (IBS) differed from non- IBS clients in terms of their defense mechanisms. Although irritable bowel syndrome (IBS) is one of the most common gastrointestinal disorders encountered by primary care physicians and gastroenterologists, it is one of the least well understood. Part of the reason for this is the lack of real consensus of opinion regarding the nature of the complaint (Read, 1985). Today it is widely agreed that irritable bowel syndrome is a psychosomatic disorder, that is, a disorder of physiological functioning and anatomical structure, which are determined for most part by psychological factors (Lachman, 1972; Moser, 1986). Evidence linking psychological variables to gastrointestinal disorders is surprisingly sparse, and all too often confusing and contradicting. Such conflicting results probably reflect the many methodological weaknesses common to all areas of study (Bennett, .1989). Although evaluation of the impact of psychological interventions on both symptomatic and psychological relief has been pursued, its findings provide tangential support for the importance of psychological disorders. Nevertheless, these studies have shown a consistency of positive results not found in the etiological research (Read, 1985). Using a variety of techniques, most with the therapeutic goal of stress reduction, psychological therapy has been shown to produce. symptomatic relief, increase periods of remission, and to reduce the impact of stress resulting from severe symptomatic flare ups in IBS (Bennett, 1989). In .addition, most IBS patients may not identify their gut symptoms in psychological terms. Therefore, they inappropriately and repeatedly subject themselves to unnecessary, expensive and harmful medical procedures in search of an organic cause. Further research into the psychological factors of IBS, including the defense mechanisms underlying it may lead to a reduction in type of anxiety (Folkman, Lazarus, Gruen & DeLongis, 1986). The ways in which people cope with intense emotions may have a significant effect on their psychological and physical health. StresS factors and the suppression of emotions, for example through defense mechanisms, are thought to be especially relevant in the etiology and exacerbation of psychosomatic illness (Ogden & Von Sturmer, 1984). The role that defense mechanisms play in the development of IBS forms the cornerstone of the present research.

M.A. / A review of existing relevant literature and research confirms that there is not always unanimity about the diagnosis and classification of the Post-concussion syndrome (PCS). This controversy arising from the diagnosis results in the failure to inform, prepare and equip the patient and his family adequately for the effects of PCS. This influences the treatment and eventual rehabilitation of a patient who has a light head injury. It is, therefore, essential that the medical field, over the whole spectrum of medical disciplines, should fully understand PCS and the patient, and should also provide the patient's support system with the necessary information with regard to the effects of PCS. This will, in truth, affect the rehabilitation of this patient. An investigation of the literature showed that most light head injuries are the result of road accidents, followed by industrial and factory accidents. Other types of head injuries and alcohol abuse play a further role in the appearance and degree of seriousness of light head injuries. The effect of PCS symptoms range from physical discomforts such as headaches to more emotional problems such as depression, fatigue, anxiety and concentration problems. Primary symptoms fade with the passing of time while secondary symptoms increase after the first few months after the head injury. The experience of PCS symptoms can be influenced by different factors such as pre-trauma personality traits, accident neurosis and compensations. It is postulated that the experience of typical PCS symptoms can be mediated by sufficient understanding, knowledge and realistic expectations on the part of the light head injured patient. The aim of the study was to address the problem of insufficient information provided to patients suffering from PCS regarding the symptoms they are likely to suffer. This was done by creating a post-trauma information program consisting of an attractive and multicoloured booklet with easy access to various issues such as explanation of terminology, the neurology of concussion, likely symptoms, prognosis and recovery time. The booklet was complemented with a casette recording of relevant issues, presented in different voices, with a calming musical background. The patients who were selected to participate in the evaluation of the program had all presented at the 1 Military Hospital over a period of 18 months with firmly diagnosed PCS based on scores obtained on the Galveston Orientation and Amnesia Test (GOAT) and the Glasgow Coma Scale (GCS). A total of 81 white, male subjects were selected. All the subjects complied with certain criteria such as Afrikaans or English language proficiency, falling within a particular age group (16 - 35 years) and with no prior neurological or psychiatric disease. The 81 patients were randomly divided into groups according to the Solomon fourgroup design. Pre tests were administered to the two experimental groups. The pre tests consisted of four subscales of the Profile of Mood States (POMS) and four subscales of the Personal, Home, Social and Formal Relations Questionnaire (PHSF). The validities and reliabilities of these scales are wel documented. The four selected POMS subscales were: Tension-anxiety Depression-dejection Anger-hostility Fatigue-inertia The four selected PHSF subscales were: Self-esteem Self-control Health Formal Relations One experimental and one control group now received the intervention program.
