Dissertations / Theses on the topic 'White cane'

For millions of visually impaired individuals worldwide, independent navigation is a major challenge. The white cane can be used to avoid obstacles close-by, but it does not aid in navigation as it is difficult to get a large-scale view of the environment. Technological aids have been developed, notably ones based on GPS, but they have not been widely adopted. This thesis approaches the problem from different perspectives. Firstly, current navigation aids are examined from a user-interaction perspective, leading to some design guidelines on how to present spatial information non-visually. Secondly, a prototype of a new navigation aid (the Virtual White Cane) is proposed, and a field trial with visually impaired participants is described. The idea behind the Virtual White Cane is to utilise the intuitive way humans avoid obstacles by touch, and specifically to leverage the experience white cane users already have. This is accomplished by scanning the environment with a laser rangefinder, and presenting the range information using a haptic interface. The regular white cane is easy to use because it behaves like an extended arm, and so does the Virtual White Cane, albeit working at a much greater distance than the regular cane. A field trial with six experienced white cane users was conducted to assess the feasibility of this kind of interaction. The participants carried out a trial procedure where they traversed a prepared environment using the Virtual White Cane. They did not receive extensive training prior to the trial, the point being that if the Virtual White Cane behaves like a regular one, it should be quick to learn for a white cane user. The results show that spatial information can be feasibly conveyed using a haptic interface. This is demonstrated by the ease with which the field trial participants familiarised themselves with the system, notably adopting a similar usage pattern. In interviews that were conducted following the trial procedures, the participants expressed interest in the idea and thought that being a white cane user helped them use the Virtual White Cane. Despite knowing how to operate the system, the participants found locating objects to be difficult. An extended training period would likely have made this easier, but this problem could also be lessened by understanding what model parameters (such as the length of the virtual cane) should be used.

This thesis examines cultivation in the lives of Sarah and Columbia Bennett between the years 1852 and 1874. The Bennett women's letters convey an intimate sense of the agro-economic preoccupations (and gardening pleasures) of these slave-owning white women, and the centrality of cultivation in mid-nineteenth-century rural Louisiana within a landscape of country stores, plantations, and people. As the lives of the Bennett women illustrate, white women's gardening knowledge and practice formed a cornerstone of central Louisiana society. The Bennett women's gardening knowledge and skill were primary components in the creation of a self-sustaining plantation household. By cultivating produce and other foodstuffs for consumption, the Bennett women made possible the family's participation in the lucrative market for cotton and other cash crops, a market that also tied their household to plantation economies elsewhere in the transatlantic world.

The prevalence of diabetes along with the perceived impact of sugar on health in general has increased the demand for reduced-sugar and sugar-free baked products. Cakes typically contain large quantities of sucrose which affects not only flavor but also color, volume, and texture. This study evaluated the effect of replacing sucrose in white layer cakes with polydextrose and two artificial sweeteners: sucralose and stevia extract. White layer cakes were made using AACCI Method 10-90.01. Batter properties were evaluated by measuring specific gravity. Volume index was measured using a cake template (AACCI Method 10-91.01). Slice area, number of cells, number of holes, and wall thickness of the crumb were calculated and recorded using C-Cell Cake Imaging system. Control batter made with 135% water had a specific gravity of 0.90 g/cc and a cake volume index of 112. The cakes had a nicely golden brown, shiny surface. The crumb grain was fine with an even cell distribution. Optimum water level and baking time were obtained for each cake variation. Although replacing sucrose with polydextrose had no significant effect on specific gravity (p>0.05), a 25% replacement resulted in a cake with a volume index of 110, 50% with an index of 105, 75% with an index of 103, and 100% with an index of 97. The crumb grain was similar to the control cake. Adding sucralose and stevia yielded similar results, where lower volumes were recorded as polydextrose and sucralose/stevia were increased in the cake formula. Complete replacement of sucrose with polydextrose and sucralose or polydextrose and stevia produced an acceptable volume of cake. The number of holes and wall thickness of the crumb was not significantly different in any cake variation. Therefore, polydextrose and both sucralose and stevia are suitable as sucrose replacers in cakes. Key indexing terms: cakes, polydextrose, stevia, sucralose.

This thesis explores the relationship between architecture and the blind people. For better clarity and understanding of the topic, The work has been divided into five distinctive parts. In the first, introduction part, I approach space sensation of a blind person from the physiological and psychological angle. This analysis is very important for the understanding of imagination, which the blind person has. Another important fact to understand is the way in which the blind person gets the information about the space and what is his ability to process it. Further, I explain the basic principles of the blind person’s movement through space and describe instructions of how to help blind people in the concrete spatial situations. In the next part, I give a short information about the historical progress of the relation between the society and the blind people. An important fact is that, as late as 200 years ago, the blind people were considered as “sub men” and did not have the full freedom privilege. This relation has been modified over time and nowadays, the blind people have the freedom of movement and all the rights to enjoy their lives. To meet the needs of the blind people, many associations have been created that act on their behalf. The associations have different modes of functioning, but their common goal is to help blind people with their social rehabilitation, looking for employment and removing architectural barriers. The core of my work is divided into two parts. In the first one, I focus on the problematic of the blind people and architecture from the functional aspect. The functional aspect is vital for the blind people. It corresponds to their safety in the environment. In this chapter, I treat in detail basic elements for designing buildings, for specifying barriers and principles of design for blind people. Furthermore, I describe the help tools the blind people need in order to move in the space. I evaluate the future of these tools and indicate the rapid technological progression which makes the life of blind people more comfortable. In the next part, I focus on the problematic of the blind people and architecture from the aesthetic aspect. This question has not been much explored yet, but is, nonetheless, very important. In this part of my work, I use more my personal experience and the knowledge coming from the exploration of space. Aesthetical values are subjective for all the people, with or without a handicap. Therefore, in this final chapter, I try to note the facts that can be used in the process of the aesthetical perception and to reflect on them. In the domain of aesthetical research, there also exist tools and institutions that help blind people in their comprehension of architecture. The division of my work emerged from the compilation of diverse facts in the process of writing. This thesis has an informative and practical character. It is intended for people who want to understand and to be informed about how to design architecture for the blind people. It will be directed towards people who build this kind of architecture and need an overview of how to make it. It is also intended for people interested in learning more about architecture.

It has been 25 years since the demise of apartheid and yet white dominance still persists. With many significant changes visible as a result of the fall of apartheid, the country sadly remains racially divided. The black majority still lives in poverty while the white minority continue to hold their position of privilege and power. And while black people are trying to change the status quo, most white people are ignoring their role in the past while continuing to perpetuate their White Privilege as the gap between black and white widens. Not addressing the issues of the past, maintains the unearned privileges white people have, while the black community grows even more frustrated as the year’s pass. With this in mind, this study explored a sample of “ordinary people” in the Western Cape Province, South Africa, and their experience and knowledge of the phenomenon known as “White Privilege”. The goal was to develop a conceptual framework for understanding the specifics on how White Privilege functions and operates within the Western Cape and its impact on those who are excluded from perks related to White Privilege. This study confirmed the existence of White Privilege in the Western Cape. The impact of White Privilege on people of colour, and society at large, is where a small group of the research participants had different views. Some linked White Privilege directly to the continued oppression of people of colour, and the unfair position of privilege that white people occupy in society. Others viewed this Privilege as an unintended occurrence, which they should not be held accountable for. The critical point that all participants agreed on was that White Privilege in the Western Cape is a problem, and something that needs attention A.S.A.P.

The endangered white-cheeked crested gibbon (Nomascus leucogenys), native to Laos, Vietnam, and perhaps China, remains little known and highly threatened. I studied seasonal variation in the diet, activity budget, and ranging behavior of three groups of white-cheeked crested gibbons in Nam Kading National Protected Area, Bolikhamxay Province, Laos, over 12 months in wet seasonal evergreen forest. Crested gibbons (Nomascus spp.) are speculated to be more folivorous than other gibbons, but this has never been confirmed because of the paucity of fieldwork on the genus. I studied diet in relation to forest seasonality to determine the contribution of leaves to the diet over an annual cycle. Although leaves were the main dietary item throughout the year (53-85% of monthly diet), gibbons substantially increased their consumption of fruit during periods when it was most abundant in the forest. Because fruit is a calorically rich source of food, gibbons seek fruit when it is abundant and obtained easily. Young leaf consumption increased when they did not have access to fruit, indicating that their diet is flexible but strongly dependent on seasonal availability of resources. In addition, rainfall had a negative association with fruit abundance and fruit in diet. Activity budgets are an important aspect of a species' ecology because they are directly related to home range use, energy allocation, and diet, but they have never before been studied in gibbons (Nomascus spp.) of the rainy, mountainous, forests of Laos. Annually, the three groups that I studied spent nearly equal amounts of time resting (30%), feeding (33%), and traveling (35%), but only a small amount of time singing (2%). However, the proportion of time allocated to different activities showed significant seasonal variation associated with rainfall and diet, and correlated with home range use. Gibbons increased traveling time and decreased feeding time when they ate more fruit, and they decreased traveling time and increased feeding time when they ate more leaves. When the gibbons spent more of their time traveling, they also had longer day range lengths, and used a higher percentage of their total home range. Moreover, when rainfall was high, the gibbons decreased traveling time and increased time resting and feeding. Average home range size was 37.9 hectares and daily average distance over which the gibbons ranged over the 12 month study was 1.48 km per day. Differences existed among the three groups. Overall, white-cheeked crested gibbons have a home range similar in size or larger than frugivorous gibbons, and larger than the folivorous siamang. Ranging was highly seasonal with shorter day ranges during times of low fruit availability and consumption. During times of high fruit availability and low rainfall, the gibbons took on an energy maximizing strategy where they maintained large home ranges, traveled longer distances and consumed larger quantities of fruit. Gibbons and their habitat in Laos have faced continuous threats over the past 10 years because of large scale development projects and subsistence hunting. Given the highly threatened status of the species in Vietnam and China, the Lao population is certainly the world's largest and the best hope for conservation of behavioral, ecological, and genetic diversity. Resources for conserving species in the country are very limited, and wildlife populations are already greatly fragmented. I describe the current conservation issues and based on the dietary and ranging information that I collected, recommend important conservation measures to safeguard the remaining populations of endangered gibbons from extinction.

Title: Towards Equality – Oppressed Non-White Women in Cape Town, South Africa

Subject: Sociology

Level: Undergraduate thesis, D-level, 10 p.

Department: School of Social Science

Tutor: Svante Lundberg

Supervisor: Anders Nilsson

Prior to the first democratic election in 1994, South Africa experienced the racist and sexist legislation of apartheid. The democratisation was surrounded by violent struggles amongst the non-white population and the issue regarding gender had to step aside in favour of the struggle against racial discrimination.

This study focuses on how the lives of the underprivileged non-white women in Cape Town are affected by the post-apartheid changes. This area will be divided in to four more specific topics: civil society, human rights, collaboration between civil society and the Government and power structures that affect the development and lives of the women.

Our methodology is based on interviews with women with insight in the problem area, participant observation, and secondary material constituted by legal sources, reports and statistics.

The main findings can be summarised with mentioning that the deprivation are based upon five different dimensions: poverty, isolation, physical weakness, vulnerability and powerlessness. They are all closely linked to violations of human rights, and in order to create a complete picture power is of great significance. There are three different views on power, all of which are surrounded by a complexity of problems. This can be wrapped up in the statement that the society as a whole is permeated by underlying power structures that makes the non-white women of South Africa doubly exposed.

White rhino populations did not occur historically in the Eastern Cape, South Africa (Skead 2007). They have, however, been introduced into a number of reserves within the Eastern Cape for reasons such as conservation, ecotourism and hunting. Based on the literature on the species, it was hypothesized that white rhinoceros would have been introduced in grass-rich habitats, as they are bulk grazers. White rhinoceros populations were further assessed in terms of population establishment by outlining their distribution and performance since introductions and this was done by extracting intercalving intervals from the literature of native populations and comparing such to the Eastern Cape intercalving intervals, extracted from data obtained from landowners. Finally, the diet of white rhinoceros was quantified, in order to identify plant species potentially at risk from white rhino herbivory using Shamwari Private Game Reserve as a study site. The distribution of white rhino in the Eastern Cape varies in terms of habitat and vegetation types. The majority (62%) of white rhino are located in grass-poor habitats and are primarily there for ecotourism purposes with only a small percentage kept for conservation purposes in the state reserves. Limited data for intercalving intervals of the white rhino in Eastern Cape are comparable to those of populations in the natural range. The ex situ conservation of white rhino in the Eastern Cape proved to be a success as population numbers have increased markedly since the first survey was conducted (Buijs 1999). The diet section of this study showed that white rhino are highly selective grazers even in a grass-limiting habitat which is dominated by browse. Twenty-five principal dietary items were identified in their diet, with only six being preferred in autumn. These are thus the plant species that could be the most vulnerable to white rhino herbivory. Supplementary food provision plays a big part of the feeding scheme of white rhino in Shamwari Private Game Reserve during the winter season, revealing the little confidence that the management has on natural resource availability to the animals at this time. These findings support the value of the Eastern Cape for ex situ conservation of white rhino, and highlight plant species potentially at risk. There is a need for further research on the population performance of these animals, and the plants identified here need to be monitored to assess white rhino impact on the vegetation

This study sought to uncover an understanding of the phenomenon of being nurtured while being treated for depression as an in-patient in a psychiatric hospital. The literature review undertaken for the study revealed that the phenomenon of being nurtured is poorly understood and that there is little research on this important topic. Nursing ,practice fosters the opportunity for interpersonal, professional nurturance between nurse and client, and promotes the growth and development of the client. Yet, nurturance is described in the nursing literature as an aspect of care giving rather than as a concept in its own right. Care giving has been given priority in the nursing literature, but despite the quantity of literature which is mainly from the health professional's perspective, the term care has become a commonplace expression. The, identification of care with the emotions creates confusion for nurses who want to provide professional client care without becoming unduly involved with the client. It is suggested that the nursing profession consider nurturance as a more suitable term to describe nursing practice, as nurturance has not become a commonplace phrase and it is not in itself an emotional term. The literature on depression informs us that the depressive disorder is very common in Western society. Although there are numerous studies investigating depression, the majority of these are from the perspective of the health professional rather than the individual diagnosed with the depressive illness. Thus, the strength of this study is that it investigates the phenomenon of depression from the perspective of the patient's experience, rather than from the scientific or natural attitude adopted from the perspective of the health professional. The study was guided by Husserlian phenomenology and the Giorgi (1975) approach to phenomenological data analysis. Seven individuals who were hospitalised with a diagnosis of major depressive illness were asked to participate in the study. Each participant was asked to describe their experience of being nurtured in weekly interviews conducted throughout the period they were in hospital. The number of interviews conducted with each participant varied from one to ten. The investigator's experience of data analysis highlighted the difficulties of the phenomenological reduction, particulary when the participants' suffered loss of memory following treatment with electroconvulsive therapy (ECT). Although the difficulties of bracketing of one's assumptions are raised, the investigator concluded that the phenomenological reduction is the strength of the phenomenological method and thus must not be cast aside without adequate consideration. The participants' described the moments of nurturance as being related to the nurse's reassuring presence, especially when their communications were sincere and portrayed an interest in the patient as a person. The study promotes the need for nurses to set aside their natural and scientific assumptions so that they may understand patient's experiences from the lifeworld. Nurses who are able to adopt this attitude will accept the patient's experience and take the opportunity to understand them. Thus, the patient's experience is no longer seen as being as a result of their symptomatology but as an expression of the human need for nurturance.

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.

The underrepresentation of gifted Black and Biracial students is a pervasive problem in and of itself, and indicates a much larger struggle of disproportionality of Black and Biracial students who are not called upon or supported in efforts to meet their academic potential. Therefore, an evaluation of the inequity generated by gifted education is warranted. It is true that the majority of gifted programs are often predominantly White. Accordingly, Black and Biracial students who qualify for gifted programs may face unique challenges in their development of racial identity and their socio-emotional health. Using ethnographic techniques, this case study explored the ways that Discovery School, a predominantly White gifted school (PWGS), addresses race. It asked how Black and Biracial students at Discovery School understood themselves as racial beings. The fundamental research questions that guided this study were: (1) how is race addressed at a PWGS, and (2) how does a student of color feel Otherness at a PWGS? The case study was designed, and findings were analyzed, through the theoretical lens of critical race theory. Data was collected through several means, including interviews, surveys, direct observation, and email prompts. Interviews were conducted with four gifted students of color, three teachers, and three parents. Surveys were sent home for student participants and their parents to fill out together. Teachers and administrators were asked to complete two email interview questions. Throughout the data collection, I frequently observed students learning and playing at the school and recorded field notes. Findings indicate that: 1. Talented and gifted students thrive in programs that are uniquely tailored to meet their advanced academic and cognitive needs. 2. Policies and inadequate communication act as barriers for gifted Black and Biracial students. 3. Within a positive educational community, racial microaggressions- including the silencing of racial dialogue and individual bullying- exist. The results of this study suggest that Discovery School operates in ways that benefit the participants of the study. Overall, the student participants (and most parent participants) were satisfied with their experiences at Discovery School. Additionally, results indicate that Discovery School could strengthen their program with a commitment to diversifying the student population and implementing culturally responsive pedagogy and antiracist practices that change the consciousness of education professionals and offer support systems for gifted Black and Biracial students, and develop curriculum that is more reflective of students of color.

The purpose of this study is to explore Filipino service care providers’ experience of compassion fatigue. Compassion fatigue is a common experience among health care professionals and can contribute to feelings of hopelessness and adverse behaviors in caring for patients. In California, there are a large number of Filipinos who are employed as care providers for older adults; however, there is limited research available regarding Filipino workers in the United States. This study took on a qualitative design that utilized face-to-face interviews to gain more insight into Filipino service care providers’ experience of compassion fatigue in relation to their employment. Factors that were explored in interviews were exposure to terminally ill individuals, coping and self-care strategies, and working environments. The results of this study indicated participants appeared to experience compassion satisfaction, rather than compassion fatigue. Furthermore, recommendations for future research were discussed. These recommendations included the need to explore experiences of compassion satisfaction in this population and to look into the experience of Filipino service care providers who were born in the United States, rather than in the Philippines, to determine whether Filipino cultural values of caring can act as a buffer against the effects of compassion fatigue.

Using data from the Household Component of the 1996 Medical Expenditure Panel Survey, the study compares (1) the accessibility, and (2) the predictors of health care services utilization among African American and non-Hispanic White males, 18 to 65 years old in the United States. Using ANOVA procedure in comparing the means for use of physicians, hospitals, doctors, and difficulty obtaining care, seven hypotheses were tested in the study. First, it was hypothesized that African American men of working age will have less access to health care services (physicians, hospitals, and dentists), and be more likely to report having experienced delay or difficulty obtaining care, compared to non-Hispanic white males of working age. Second, it was hypothesized that, controlling for health status, African American men of working age will have less access to health care services (physicians, hospitals, and dentists), and will also be more likely to experience delay or difficulty obtaining care, than non-Hispanic white males. This was followed by the third hypothesis which compared utilization of physicians, hospitals, dentists, and difficulty obtaining care among African American and non-Hispanic white males, controlling for health status and insurance coverage (any insurance, private insurance, any public insurance, and Medicaid). Hypotheses four through six compared the utilization of physicians, hospitals, and dentists, as well as difficulty obtaining care among African American and non-Hispanic white males, controlling for the following variables sequentially: health status and poverty status; health status and having a usual source of care; and health status and employment status, in that order. Finally, it was hypothesized that, controlling for health status, any insurance, poverty status, and employment status, African American men of working age will have less access to physicians, hospitals, and dentists, and experience more difficulty and delay obtaining care, compared to non-Hispanic white males of working age. Results from the study indicated that Hypothesis 1 was supported for use of physicians and dentists. Hypotheses 2, 3a and 3c were supported for use of physicians, hospitals, and dentists. Hypotheses 3b, 3d, and 4 received support for use of physicians, hospitals, dentists, and difficulty obtaining care. Additionally, both Hypotheses 5 and 6 were supported for use of physicians, hospitals, and dentists, with the last hypothesis being confirmed for use of physicians, hospitals, dentists, and difficulty obtaining care. The study calls for a closure of the gap in access to health care between African American and non-Hispanic white adult males in the US. A reform-oriented government-sponsored single-payer plan modeled after the Canadian health care system is recommended for the United States. A national health insurance plan is most likely to ensure equity of access, compared to others, in the sense that it is founded on the premise that everyone will be covered in a similar fashion. Considering the role of Community Health Centers in serving Medicaid and Medicare recipients, low-income uninsured and insured, the underinsured, as well as high-risk populations and the elderly, in the interim, they should be extended to every community in the United States.

The focus of this thesis is on the care career patterns of black children. Empirical findings of the research are analysed in the light of existing literature. Particular attention is directed towards the decision-making role of field social workers. The study examined the perceptions of the principal individuals associated with the care process (namely field social workers, natural parents and children). A cohort group of 564 children were found to be in the care of Wenford Social Services Department (294 black and 270 white) . The care careers of these children were explored. A follow-up study conducted six months after the initial inquiry was part of this process. Also, a sub-group of 80 children (who had been admitted into care within the previous six months) were examined in depth. Here, interviews with the principal individuals were conducted to gain their perception of the situation. Both the cohort and the sub-group included children of all ages and all legal routes of entry. In the sub-group, restrictive criterion liable to bias results was applied in that only children who had been admitted into care in the previous six months were selected The study attempted to analyse the similarities and differences in the treatment of black and white children in the public care system. Results shed new light on the situation of black children and suggest that due to individual and institutional racism within the personal social services, black families and children receive a poor service.

This study seeks to provide information relevant to public policy that will lead to increased access and utilization among this vulnerable population and to reinforce the validity of the behavioral model for vulnerable populations. This study is a secondary analysis of data collected in a study that examined adult, working-aged patients within the John Peter Smith Health Network, which is a large, urban, tax supported county health care system in Fort Worth, Texas. From a sampling frame of 10,000 patients, the study analyzed data for 243 low-income, white, working-age males, collected from computer assisted telephone interviews in 2000. Cross-tabulations and bivariate logistic regressions were used to analyze the effect of 8 independent variables (age, marital status, insurance, employment status, a usual source of care, competing needs, experiences with paperwork, and perceived health status upon 5 dependent variables pertaining to unmet health care, unmet prescription medicine needs, unmet dental needs, utilization of doctors in emergency departments, and overnight hospital stays. The results show the safety net system is failing to meet the needs of this vulnerable population. The findings indicate white men who found it necessary to forgo health care due to other needs were almost five (4.973) times as likely as those who did not find it necessary to forgo care due to other needs, to report having a problem getting the health care that they need (p = ≤ .001). The odds of having a problem getting needed dental care are about 66% lower for white men who have private insurance through work compared to those who do not have private insurance through work (p ≤ .05).

The social service care system for the elderly has undergone a number of changes during the last decades. These reforms, especially the purchaser-provider split, have changed the role of the state in this sector somewhat, from being a monolithic provider of tax-financed elderly care to primarily being a purchaser who might choose to purchase elderly care services from private providers. However, the state has still retained a public elderly care service. Needless to say, the reform paved the way for a number of private enterprises in the area, causing competition between public and private providers. Adherents of the reform have argued that private providers can improve efficiency, while opponents have claimed that the chase for profit might affect the quality of the care in a negative way.

This study focused on the basis for this controversy by examining the relationship between factors such as profit, efficiency, care quality, incentives, motivation and productivity. The study was performed by interviewing thirteen employees and managers in four different care organizations (of which half were public and the other half private). Their answers were analyzed from three theoretical aspects; incentives and motivation, efficiency and productivity, and care quality.

The findings were that, since the revenue size is beyond their control, private providers can only create profits by reducing costs in a number of ways. Some of these ways, such as cutting down on education, team building activities and salaries, might be detrimental for the company in the long term (and thereby increase costs over time) and have adverse effects on quality. Others, however, such as increasing the efficiency of non-care activities (less administration and optimized scheduling, for example), avoid hiring overqualified staff and instead providing them with enough education for the task at hand, and optimizing work hours, might be more enduring over time and have none or small adverse effects on quality. More dispiritingly, it was also shown that the purchasers do not have any real knowledge about the quality of the work performed, regardless of the provider being private or public, and that in some municipalities users are denied to choose provider for themselves.

'White Shark Cage Diving' (WSCD) enables tourists to experience a face-to-face encounter with wild sharks in the open water. In order to attract the animals close to the cages, tour operators often use chum, bait, or decoys, which interferes with the natural habits of marine wildlife. These practices have great potential to adversely impact animals and the marine environment, with unknown long-term consequences. Globally, South Africa has the most extensive WSCD industry. The management is based on a policy paper and regulations published in 2008 by the Minister of Environmental Affairs (a ministry which also included Tourism). This thesis discusses the question of whether South Africa's WSCD industry is appropriately regulated in the light of today's best practices. South Africa's regulatory framework will be compared to the management arrangements of other jurisdiction where WSCD takes place. The ultimate objective of this thesis is to determine whether the South Africa's WSCD regime strikes a sustainable balance between commercial interests and the need to protect this elusive creature.

Thesis (MScAgric) -- University of Stellenbosch, 2002.
ENGLISH ABSTRACT: The table grape industry is a major contributor to the South African economy, directly through foreign earnings from this predominantly export-based industry, as well as indirectly through the employment of thousands of people. It is a growing industry and consists of several production areas. The fastest growing table grape production area in South Africa is the Lower Orange River area, which produces some of the earliest grapes in the Southern Hemisphere. The biggest river in South Africa irrigates this area and it has an extreme climate characteristic of semi-desert areas. This area is considered to be optimal for the production of high quality, early, white seedless grapes. Previously, this area was predominantly planted to Sultanina vines for the purpose of raisin production. When seedless table grapes became a consumer preference, the producers very successfully converted their production practices to yield export quality seedless grapes from the established Sultanina vineyards. Extensive new plantings as well as re-plantings occurred in this area, also including newer cultivars from local and overseas breeding programmes. Being a viticultural and economical hot-spot, the Lower Orange River area is attracting much attention as a table grape production area and it also formed the backdrop to this study. The cultivar profile is changing in the area and it is projected that Sultana-, Regal-, Prime Seedless and Sugraone will be the four major early, white seedless cultivars in 2005. Based on this knowledge and prompted by a lack of information regarding production costs and general profitability of the new cultivars, this study was initiated in the form of a comparative analysis between the four mentioned cultivars spanning the early, middle and late regions of the Lower Orange River area. The approach used extracted information regarding cultural input costs (specifically labour as man-hours and the consequent costs) per manipulation performed in the vineyards. This approach is different from the more general method of obtaining input costs for a specific area based on combined mean values, often not distinguishing between cultivars. The specific aims of the study included a comparative analysis of input costs for production cultural practices per main manipulation action, as well as a comparative analysis taking into account productivity, value and extraordinary costs related to each of the four cultivars. To this end, 22 experimental plots were identified for use in the study. Collaboration of the production managers of each of the experimental plots were procured and information regarding production costs per manipulation and productivity of each cultivar and experimental plot were extracted from their own record keeping systems or from documents provided to the production managers. The value (price achieved) of the various cultivars for the 2001/2002 table grape season were put into perspective by using data from a survey which included information regarding payments for the various cultivars during the season in the Lower Orange River area. Information regarding fruit and vine royalties was obtained from the various plant breeders' rights holders of the various cultivars, where applicable. Primary descriptions of each experimental plot concerning general cultivation practices and information regarding the specific season were used to qualify results obtained from the various blocks. Several complicating factors impacted on the study and specifically the subsequent analyses of the results. Some of the factors were already identified as complicating factors in the planning stage of the study and were mostly linked to the recent introduction of two of the cultivars to the Orange River area. From the data gathered and the analyses performed it became clear that it would be difficult to discern significant differences (where significant is defined as PS0.10), but clear trends were observed and indications obtained. Based on the input cost analyses of this study it is proposed that mature Prime Seedless will have the highest labour input and cultural production cost of the four cultivars, followed by Sugraone. The labour input and the cost for the production cultural practices studied for young Prime Seedless vines were very high in comparison to the mature Sultana Seedless and Sugraone vines, especially for the canopy management and bunch manipulation actions. Prime Seedless was especially prone to the set of small and uneven berries, which lead to very high labour input requirements and subsequent cost for bunch manipulations. Sugraone is also known for the set of small and uneven berries in the Lower Orange River area, especially in difficult climatic seasons, also requiring high labour input for bunch manipulations. The initial indication is that mature Sultana- and Regal Seedless will require similar labour inputs for cultural production practices. The fact that Regal Seedless does not require expensive gibberellic acid (GA) applications, or girdling for thinning and berry enlargement purposes, is a tremendous advantage from a production cost point of view. Accordingly, initial indications are that Regal Seedless will have the lowest cultural production cost of the four cultivars. Regal Seedless was prone to the set of uneven berries during the year of study and accordingly it is suspected that this factor will ultimately determine the labour requirements and cultural production input cost, especially in difficult climatic seasons. The labour input and ultimately the cultural production cost for Sultana Seedless will be determined by the correct timing and concentration of the GA applications for thinning and berry sizing. Sultana Seedless and Sugraone produced high yields during the 2001/2002 table grape season in the Lower Orange River area. Yield information from the various experimental plots confirmed that there is little to choose between the two cultivars in terms of yield when cultivation conditions and practices are optimal. Large variation was observed in the yield results from the Regal- and Prime Seedless experimental plots. This is largely due to the recent introduction of the cultivars to the area and the consequent scarcity of blocks of these cultivars that are in full production. It was impossible to identify clear trends in terms of the future productivity of mature Regal- and Prime Seedless, but some indications of labour inputs could be extracted and qualified. Early maturing Prime Seedless and Sugraone performed very well in terms of price, especially in the harvest period prior to week 50. This advantage of high prices early in the season is, however, not always applicable to early cultivars in the later maturing regions of the Lower Orange River area. Later during the season, after week 50, when the supply of table grapes to the overseas markets has increased sharply, Sultana Seedless is usually the best performer in terms of price of the four cultivars. The ultimate price obtained by a cultivar is to a large extent determined by supply and demand, quality and acceptance of the specific cultivar. This study and its outcomes have a strong regional (Lower Orange River) and local (South Africa) impact and the specific results will undoubtedly be valuable to the producers, exporters and other role-players with vested interest in the cultivars studied or in table grape production per se. The methodology adopted in this study, however, is of broader interest and dearly shows the advantage of having detailed and qualified information regarding cultivation practices and bringing it in relation to the labour and consequent costs required per action. This should lead to more business intelligence and realistic planning on the producer side when decisions regarding the choice of a cultivar for a specific production area with a particular marketing scope have to be made. This study has also paved the way for similar studies, specifically with regard to the detailed description of the methodology that was established. Knowledge of the problems experienced in this study provides a useful reference for the planning and execution of similar studies.
AFRIKAANSE OPSOMMING: Die tafeldruifindustrie dra grootskaals by tot die Suid- Afrikaanse ekonomie: regstreeks deur middel van buitelandse valuta vanaf hierdie hoofsaaklik uitvoer-gebaseerde industrie, asook indirek deur werkverskaffing aan duisende mense. Dit is 'n vinnig groeiende industrie en bestaan uit verskeie produksie-areas waarvan die Benede-Oranjerivierarea, waar van die vroegste druiwe in die suidelike halfrond geproduseer word, tans die meeste groei toon. Die grootste rivier in Suid-Afrika vloei deur hierdie gebied wat deur uiterste klimaatstoestande, soortgelyk aan die van semi-woestyngebiede, gekenmerk word. Hierdie gebied is baie gunstig vir die produksie van hoë-gehalte, vroeë, wit pitlose druiwe. In die verlede is hoofsaaklik Sultanina vir die produksie van rosyne in hierdie gebied verbou. Namate pitlose tafeldruiwe voorkeur begin geniet het onder verbruikers wêreldwyd, het produseerders in die area hul verbouingspraktyke suksesvol aangepas vir die produksie van uitvoergehalte tafeldruiwe vanaf die grootskaalse, reeds gevestigde Sultanina-wingerde. Uitgebreide aanplantings en heraanplantings, wat nuwe cultivars van plaaslike en oorsese teelprogramme ingesluit het, is in hierdie gebied gedoen. Die vinnige groei in tafeldruifaanplantings en -uitvoere, asook die ekonomiese impak van die industrie in die Benede-Oranjeriviergebied, het die afgelope aantal jaar sterk op die voorgrond getree en het gevolglik gedien as agtergrond vir hierdie studie. Die cultivarprofiel in dié area is besig om te verander en volgens vooruitskattings gaan Sultana, Regal, Prime Seedless en Sugraone die vier prominente vroeë, wit, pitlose tafeldruifcultivars in 2005 wees. Gebaseer op hierdie feit en na aanleiding van 'n behoefte aan meer inligting met betrekking tot produksiekostes en algemene winsgewendheid van die nuwe cultivars, is 'n vergelykende studie aangaande die vier genoemde cultivars in die Benede-Oranjeriviergebied geloods. Die benadering wat gedurende die studie gevolg is, het inligting aangaande produksie-insetkoste (spesifiek arbeid in man-ure en gevolglike koste) per manipulasie onttrek. Hierdie benadering verskil van die meer algemene metodiek om insetkoste-inligting van 'n spesifieke area van gekombineerde gemiddelde waardes te verkry. Met so 'n benadering word gewoonlik geen onderskeid tussen cultivars getref nie. Die spesifieke doelwitte van hierdie studie het 'n vergelykende analise aangaande die insetkoste van die produksiepraktyke per hoofmanipulasie/aksie ingesluit, asook 'n analise waar produktiwiteit, waarde en buitengewone koste van die vier cultivars in ag geneem is. In totaal is 22 eksperimentele persele gebruik in die studie. Samewerking van die produksiebestuurders van die onderskeie esperimentele persele is verkry ten opsigte van die verskaffing van inligting oor produksiekoste per manipulasie, en die produktiwiteit per cultivar en eksperimentele perseel. Die produksiebestuurders het die nodige dokumente ontvang om die inligting te onttrek, of kon die inligting verskaf soos dit in hul rekordhoudingsisteem voorgekom het. Die waarde (prys behaal) van die onderskeie cultivars vir die 2001/2002-seisoen is in perspektief gestel deur gebruik te maak van 'n opname wat in die Benede Oranjeriviergebied plaasgevind het. Hierdie opname het inligting oor die uitbetalings van die onderskeie cultivars in die area vir die 2001/2002- seisoen ingesluit. Inligting rakende die stok- en vrugproduksie-tantieme is vanaf die onderskeie plantttelersregtehouers van die cultivars verkry. Primêre beskywings van die algemene verbouingspraktyke van elke eksperimentele blok en inligting oor die spesifieke seisoen is gebruik om die data wat vanaf die esperimentele persele verkry is, in perskektief te stel. Verskeie kompliserende faktore het die studie en die ontleding van data beïnvloed. Verskeie van hierdie faktore is reeds geidentifiseer met die beplanning van die studie en was meestal gekoppel aan die onlangse bekendstelling van Regal en Prime Seedless aan die Benede-Oranjeriviergebied. Na aanleiding van die data wat ingesamel en ontleed is, was dit duidelik dat dit moeilik sou wees om betekenisvolle verskille (waar "betekenisvol" as PS0.10 gedifinieer is) tussen die cultivars uit te lig, maar dat dit egter wel moontlik sou wees om aanvanklike indikasies en tendense te kry. Gebaseer op die insetkoste-ontleding van die studie blyk dit dat volwasse Prime Seedless die hoogste arbeidsinsetle en produksiekoste van die vier cultivars gaan hê, gevolg deur Sugraone. Die arbeidsinsetle en koste van die produksie-aksies wat van jong Prime Seedless bestudeer is, was baie hoog in vergelyking met volwasse Sultana Seedless- en Sugraone-stokke, veral ten opsigte van lowerbestuur en trosmanipulasies. Prime Seedless was veral geneig tot die set van klein, oneweredige korrels, wat tot baie hoë arbeidsinsetle en gevolglik koste vir trosmanipulasies gelei het. Sugraone is ook daarvoor bekend dat dit geneig is tot die set van klein, oneweredige korrels in die Benede-Oranjeriviergebied (veral in moeilike klimaatseisoene), wat gevolglik tot hoë arbeidsinstle vir trosmanipulasie lei. Die aanvanklike aanduiding is dat volwasse Sultana en Regal Seedless min of meer die dieselfde arbeidsinsetle vir verbouing sal vereis. Die feit dat Regal Seedless nie duur gibberelliensuur (GS)-behandelings vir blomtrosuitdunning of korrelvergroting benodig nie, is 'n enorme voordeel in terme van produksiekoste. Gevolglik is die aanvanklike aanduiding dat Regal Seedless die laagste produksieskoste van die vier cultivars sal hê. In die studiejaar was Regal Seedless egter geneig tot die set van onweredige korrels en gevolglik word verwag dat hierdie faktor uiteindelik die arbeidsinsetle en produsiekoste van die cultivar sal bepaal, veral in moeilike klimaatseisoene. Die arbiedsinsetle en produksiekoste van Sultana Seedless sal bepaal word deur die korrekte tydsberekening en konsentrasie van die GS-behandelings vir uitdunning en korrelvergroting. Sultana Seedless en Sugraone het gedurende die 2001/2002-seisoen hoë opbrengste in die Benede-Oranjeriviergebied geproduseer. Oesdata inligting van die onderskeie esperimentele persele het bevestig dat daar min te kies is tussen die twee cultivars in terme van produktiwiteit wanneer verbouingstoestande en -praktyke optimaal is. Groot variasie is egter waargeneem in die opbrengsresultate van die Regal en Prime Seedless. Dit is hoofsaaklik as gevolg van die onlangse bekendstelling van die twee cultivars in die area en dus ook die beperkte aantal blokke van die cultivars wat reeds in vol produksie was. Dit was dus onmoontlik om duidelike tendense in terme van die toekomstige produksie van volwasse Regal en Prime Seedless te identifiseer. Indikasies van arbeidsinsette en produksiekoste kon egter wel verkry word. Vroeg rypwordende Prime Seedless en Sugraone vaar baie goed in terme van die prys wat dit behaal, veral in die oesperiode voor week 50. Hierdie voordeel van hoë pryse behaal vroeg in die seisoen is egter nie altyd van toepassing op vroeë cultivars in die later rypwordende areas van die Benede-Oranjeriviergebied nie. Later in die seisoen (na week 50), wanneer die aanbod van tafeldruiwe op oorsese markte skerp toegeneem het, is Sultana Seedless gewoonlik die beste presteerder in terme van prys van die vier cultivars. Die uiteindelike prys wat deur cultivars behaal word, word tot 'n groot mate bepaal deur vraag en aanbod, kwaliteit en aanvaarding van die cultivar deur die verbruiker. Die studie en die uitkomste daarvan het 'n sterk streeks (Benede-Oranjerivier) en plaaslike (Suid-Afrika) impak, en die spesifieke resultate salongetwyfeld van waarde wees vir produseerders, uitvoerders en ander rolspelers met bestaande belange in die cultivars of vir tafeldruifproduksie as sulks. Die metodiek wat in hierdie studie gebruik is, is egter van breêr belang en wys duidelik die voordele daarvan om gedetailleerde en gekwalifiseerde inligting aangaande produksiepraktyke te hê, wat dit ook in verband bring met arbeid en gevolglike koste per aksie. Dit behoort te lei tot meer besigheidsintelligensie en realistiese beplanning deur die produseerder met betrekking tot cultivarkeuse vir 'n spesifieke produksiearea met 'n spesifieke bemarkings geleentheid. Hierdie studie het ook die weg gebaan vir soortgelyke studies, spesifiek ten opsigte van die gedetailleerde beskrywing van die metodiek wat gevestig is. Kennis van die probleme wat in hierdie studie ondervind is, kan dien as nuttige verwysing vir die beplanning en uitvoer van soortgelyke studies.

La question du son dans les arts s'attache inévitablement à une réflexion sur les contextes de l'expérience artistique. Si les modèles traditionnels comme le white cube ou l'auditorium ne se montrent pas toujours adaptés pour accueillir les nouvelles typologies explorées dans le cadre du sonore, une véritable volonté de redessiner les équilibres des arts, d'en repenser les contextes et les modes de présentation est à reconnaître à l'origine de l'esthétique sonore. L'injonction à « libérer le son de la musique» (John Cage) n'est pas uniquement une invitation à s'opposer à l'auto-référencialité des codes musicaux; elle est à comprendre plus largement comme une volonté programmatique de repositionner l'art au- delà des barrières l'isolant des éléments contingents de la vie. Dans le contexte interdisciplinaire des née-avant-gardes, la dimension sonore offre des outils essentiels pour revendiquer une alternative à la règle moderniste. Entre visuel et auditif, entre structures spatiales et temporelles, une pluralité de stratégies d'hybridation remettent en cause les dispositifs conventionnels centrés sur l'objet artistique et sur son contenant, le cube blanc. Pourtant, les recherches sonores semblent dans le même temps faire réapparaitre l'essentialisme typique de la tradition musicale, au point de faire parler de néo-modernisme de l'art sonore. Ces aspects contradictoires sont symptomatiques de la complexité du « tournant sonore », phénomène que cette étude cherche à décrypter en retraçant quelques facteurs historiques, en analysant les discours théoriques, mais en posant aussi la question en termes curatoriaux. La documentation et l'analyse de quelques expériences que nous avons menées dans ce domaine offre l'occasion de mesurer les paradigmes qui émergent de l'analyse historique, ceux des pratiques extramurales par exemple, de l'art en situation, ou bien l'hypothèse de réciprocité entre son et site.

The author participated in an international survey organised by the British Medical Research Council (MRC) epidemiological unit in Cardiff, Wales which set out to compare the prevalence of asthma in several countries. The motivation for participating in this study was that very little previous prevalence data for asthma is available for coloured or white children in South Africa. A protocol designed by the British MRC Epidaemiology Unit was followed. One thousand one hundred and seventy four white children aged 12 years attending a random selection of primary schools in the Southern Suburbs of Cape Town were studied. A standard MRC questionnaire on asthma was completed by parents. The subjects then underwent an exercise challenge test (ECT) which involved running on the level for six minutes. During the ECT, we measured the forced expiratory volume in 1 second (FEVl) before and after the exercise. A fall in post exercise FEVl of 15% or greater was regarded as evidence of bronchoconstriction and considered diagnostic of asthma. This method is thought to identify 70-90% of asthmatics (Anderson 1985, Lee et al 1989, Pierson 1988). Using this criterion, 52 (4.4%) of the children had asthma. The prevalence of 4.4% in this study is higher than 3.1% reported in a previous study of black children in Guguletu (Van Niekerk et al, Clinical Allergy 1979). However, the age spectrum of children was different in that study. Terblanche et al (1990) report the prevalence of exercise induced bronchoconstriction (EIB) in white and coloured children to be 5.87% and 4.05% respectively. The level of FEVl reduction for a diagnosis of EIB approved for this study was lower than usually accepted. Using conventional criteria for a diagnosis of EIB, Burr et al (1989) reported a prevalence of 7.7% in Cardiff, Wales. This study confirms that exercise induced asthma is a common problem in 12-year old white children in Cape Town.

The under-provision of education for black South Africans has reached crisis proportions. While the education for black people in general is discriminatory and unequal, black rural people suffer further deprivations as there is a serious imbalance in the allocation of resources and the provision of education between urban and rural areas. Black education in the rural areas has been historically neglected for political and socio-economic reasons and, as a consequence, rural blacks have limited or no access to education. The purpose of this' study is to examine an aspect of rural education; viz: black farm schools in the 'white' commercial farming areas. It is argued that the provision of farm schools is intricately linked to the labour requirements of farmers and consequently farm schools cannot be understood independently from the social relations within commercial farming areas. The impact of local decision-making on the process of farm schooling is also significant and is an important aspect of this study. This thesis explores the political and socio-economic processes that have structured the provision of education within a small farming community, looking specifically at the effects of particular interest groups on the provision of black farm schools. The study operates on three levels. The first level provides a theoretical framework within which rural education can be better understood. It is argued that the bias towards urban areas is reflected in the current theoretical debates on the role and function of education ·in South Africa. As these theories are generally incapable of explaining rural education, an alternative model is proposed. As education cannot be understood in isolation from the rest of society, the second level of the study locates farm schooling within the broader political and socio-economic systems. This is done from two perspectives. The first perspective focuses on black education in general, tracing aspects of its development and highlighting the impact .of economic interests, white political control and black resistances to this development. The neglect of rural education is also contextualised historically and politically. The second perspective looks at rural education at a macro-level. The historical origins of the farm schools system and the effects of the relationship between agricultural capital and the state, and between farmers and farm workers on the process of farm schooling is examined. The final level of the study focuses on the micro-situation and provides an in-depth analysis of the political and socio-economic dynamics which have impacted upon the provision and process of farm schools within a specific farming community. In an attempt to understand the types of issues effecting farm schooling in this area, the attitudes of farmers, farm workers, farm- children and farm school teachers towards education are investigated. Four main issues were identified and are discussed in depth, viz: I) factors effecting the provision of black farm schools; 2) the relationship between education and the economic structure of the area; 3) the value of education; and 4) socio-economic factors effecting education in the area.

ENGLISH ABSTRACT: Transformation of South Africa's historically white universities IS evidenced by a diversification of their student and staff populations. The transition from exclusion to inclusion of minority cultures in these university campuses has not been without its challenges for those students. This study provides a record of the experiences of five coloured women who are undergraduate students at Stellenbosch University (SU), a predominantly white institution. The approach used is feminist, grounded participatory action research. Despite institutional policy initiatives, the Coloured undergraduate students in the study did not experience the university environment as inclusive. What emerged was that the women had an acute awareness of othernesses and their own minority status. Factors such as the small number of minority students and the absence of symbols or icons that reflect and acknowledge the presence of diverse cultures exacerbate their feeling of being in the minority or 'tolerated otherness'. The women experienced SU as a university where established practices and traditions continue despite the changing demographics of the student population. This type of organisational culture in which covert and overt resistance to transformation is the norm acts as a constraint on the political will to move from policy to practice and entrenches the marginalisation of minority groups. The study found that integration is left largely to personal initiative. Personal variables such as resilience, strategies for coping with stress and the resolution of identity issues, appear to playa key role in academic success. However, academic success is not always accompanied by successful social integration. Social isolation was found to have a negative impact on personal and academic confidence. Although the women in the study have had relatively negative experiences of transformation, their willingness to engage in reflexive praxis and dialogue could serve as a challenge to SU to engage in a process which acknowledges the concerns, resistance and experience of all role-players.
AFRIKAANSE OPSOMMING: Die transformasie van histories-blanke Suid-Afrikaanse universiteite word gekenmerk aan die diversifisering van hulle studente en personeel. Hierdie proses vind plaas deur die geleidelike wegbeweeg van die algehele uitsluiting van die minderheidsgroepe op die betrokke kampusse tot hulle volledige insluiting by aIle bedrywighede. Die proses is nie sonder uitdagings vir die betrokke studente nie. In hierdie studie word die ervaringe beskryf van vyf bruin vroulike voorgraadse studente aan die SteIlenbsoch Universiteit (US), 'n oorwegend-blanke tersiere instelling. Vir hierdie studie is 'n feministiese benadering wat gebaseer is op deelnemende aksienavorsing gebruik. Ten spyte van institusionele beleidsinisiatiewe om genoemde transformasie te bespoeding, het die voorgraadse bruin studente wat aan hierdie studie deelgeneem het, nie die universiteitsomgewing as inklusief ervaar nie. Dit het eerder duidelik geword dat die dames baie bewus was van hulle andersheid en hulle minderheidstatus. Faktore soos die klein aantal minderheidstudente en die afwesigheid van simbole of ikone wat die teenwoordigheid van diverse kulture reflekteer en erken, het hulle ervaring as behorende tot 'n minderheidsgroep versterk. Die dames het die US ervaar as 'n universiteit waar ingewortelde praktyke en tradisies voortgesit word ten spyte van die veranderende demografie van die studentebevolking. Hierdie soort organisatoriese kultuur waar bedekte en openlike teenstand tot transformasie die norm is, plaas 'n demper op die politieke gewilligheid om van beleid na praktyk te beweeg en verdiep die marginalisering van minderheidsgroepe. Die bevindings van die studie is dat integrasie grootliks oorgelaat word aan persoonlike inisiatiewe. Persoonlikeheidseienskappe soos gedetermineerde optrede, die benutting van strategiee om stres te hanteer en identiteitskrisisse op te los, speel blykbaar 'n sleutelrol in akademiese sukses. Akademiese sukses loop egter nie altyd hand aan hand met sosiale integrasie nie. Daar is bevind dat sosiale isolasie 'n negatiewe impak op persoonlike en akademiese vertroue het. Alhoewel die ervarings van die dames wat aan die studie deelgeneem het relatief negatiewe was ten opsigte van transformasie, was hulle tog gewillig om deel te neem aan die reflektiewe praksis en dialoog. Hierdie feit dien as 'n uitdaging aan die Stellenbosch Universiteit om betrokke te raak by 'n proses waarin die bekommemisse, weerstande en ervaringe van aIle rolspelers hanteer word.

Urban Education
Ph.D.
This dissertation poses the question, “Who cares and who does not care for poor, black, brown, red and economically disadvantaged children in urban school settings?” The study takes a deeper look at some of the underlying human dynamics that inform teacher retention and student academic achievement as an education problem, specifically related to notions of care and emotions in the urban school environment. The central focus of the study is on identifying what might be the factors that contribute to the development of a “pedagogy of care” by white female teachers, and the impact of hidden dimensions of affect in the environment on their motivations and commitment. Exploring care and fear is central to the framing of this study and is done by looking beyond the cognitive structures that inform the perceived rational processes of the teachers’ engagement in the environment. This study explores the process by which the phenomenon of care and emotions is connected to the personal and professional developmental tasks of the teachers and is viewed through the interactions of their biographies and event episodes across their life story. Phenomenological Variance of Ecological Systems Theory (PVEST) (Spencer, 2006) is used as a human development frame for situating this study. This work provides the context for understanding how pre-service teachers’ beginning identity formation is impacted by their perceptions and experiences when they enter the urban environment, and how practicing teachers’ real time experiences can help us understand the ways in which veteran teachers have negotiated perceptions and developed emotional resilience to remain in the environment. The findings of this study identified the process by which veteran white female teachers vulnerabilities led to aspects of their generative caring concerns and served as supports towards the development of their emotion-capacities and caring motives for becoming resilient in the urban environment. Data from this study could be used to help schools of education, teacher educators, professional development initiatives, and policy makers to construct and implement more appropriate and stage specific trainings, curriculum, in-service supports, and legislation that would provide a variety of critical supports to help retain teachers in urban schools.

Prior research has shown a correlation between public stigma and emergency responders' perceptions of mental health patients while providing care. However, research examining public stigma and emergency responders' perceptions of mental health patients is limited in rural areas. The purpose of this study was to explore possible relationships between the dependent variable, public stigma, and the independent variables: social distance, blameworthiness, and fear of unpredictable behavior. Link's modified labeling theory was the theoretical framework for this study. A sample of 92 emergency responders obtained from Facebook completed a questionnaire that consisted of three Likert scales. A multiple regression showed little correlation between public stigma and social distance, blameworthiness, and fear of unpredictable behavior. Only .077 of the variance in public stigma was explained by the combination of independent variables. This study has demonstrated a possible shift in societal attitudes toward mental illness. It is important to determine the cause of this change in results so that continued education regarding mental health awareness may positively affect social change.

This study sought to discover job satisfaction factors of African American faculty at a historically black university and a predominantly white institution. Data were gathered through the use of semi-structured interviews of 6 faculty members from a historically black university and 5 faculty from a predominantly white institution. Several themes emerged from the study. The most salient was that African American faculty at the historically black university were satisfied by their work with students, satisfied with the flexibility of their schedules, and dissatisfied with their pay, workload, and the lack of recognition that they receive from their institution. African American faculty at the predominantly white institution were satisfied by the impact the programs and courses they developed had upon students, satisfied with their job's freedom and flexibility, and dissatisfied with the ideas of being micromanaged or working with people who are not open and honest. The findings of this study showed that service is an important factor to job satisfaction of African American faculty and that there is a distinction between factors faculty are dissatisfied with but willing to endure and those that would cause them to leave an institution.

A measure of four types and five contexts of alienation, as well as ten personality traits, was obtained via the ·application of the Alienation Test and Howarth's Personality Questionnaire. The sample (~= 195) comprised of both high school pupils and adults drawn from the local population of English and Afrikaans speaking Whites and "Coloureds" from a town in the Eastern Cape of South Africa. These six sample groups allowed for comparisons on the measures for factors such as race, age and cultural differences. The literature review showed repeated reference to the "alienation" of the "Coloured" people of South Africa in the political, social and cultural spheres. However, the research in this area has been sparse. The main object of the study, therefore, was to determine if "Coloureds" do feel alienated, as well as the contexts of this alienation, using Whites as a comparative group. possible differences in personality traits between "Coloureds" and Whites have been associated with the differences in behaviour exhibited by these two groups, but past research has failed to find many differences. The second objective of this study, therefore, was to determine if there are differences between the personality traits of "Coloureds" and Whites, and to extend the past research. Researchers have shown that there is a relationship between alienation and personality traits, but have not adequately addressed the nature of this relationship or its implications. Following from this, the third objective of the study was to examine the relationship between alienation and personality traits, as well as their ability to predict alienation. Results on the Alienation Test showed that "Coloureds" do differ significantly from Whites and exhibit far higher levels of alienation. These differences are most marked on those types and contexts of alienation reflecting a distance from the social and political environment. Results on the personality measure showed minimal differences in personality traits between the groups. Where they were evident, they could be attributed to environmental factors. Lastly, there was a relationship between alienation and certain personality traits, but these traits had limited power to predict alienation. Taking all findings of the study into account, it is evident that the social environment, and specifically a discriminatory social environment, affects feelings of alienation to a far greater extent than personality traits. In addition, the large differences in scores of the "Coloured" and White groups on the measure of alienation and the minimal differences on the measure of personality, provides evidence that what is measured by alienation and what is measured by personality traits, are two distinctly different constructs.

The purpose of the research was to explore the theoretical models which social workers applied to the understanding of adolescents coming before the juvenile court for troublesome behaviour; and to ascertain whether different models were applied to the behaviour or family situation of black and white adolescents. The study examined the use of models derived from psychology and sociology, and considered the influence of moral values and cultural stereotypes, both within the previous research tradition in this subject, and as possible underpinning to the social workers' use of theory. A sample was drawn of 93 adolescents committed to care in London under Section 1(2)(c-f) or 7(7) of the 1969 Children and Young Persons Act. Data was taken from social work reports on the children's behaviour and family background. Analysis focussed in detail on those adolescents who had been committed to care within 18 months of referral to the social services department, and from this group a sample of 22 matched pairs of black and white children (44 children) was selected for detailed content analysis of the social workers' reports to the court. The research attempted to develop grounded theory to aid the sociological understanding of the substantive problem, and refine the understanding of three relevant sociological models: the marginal position of black social work clients in a white-dominated professional culture; the stigmatisation of social work clients, especially those from ethnic minorities; and the use of social work as a means of social control. Results suggest that social workers' use of theory is more complex than previously thought, with differential strategic use of psychology and sociology in open court and confidential file reports, and when dealing with particularly sensitive subjects such as race. Social workers developed a form of composite theorising which blended sociology and psychology in a coherent whole to meet the complexity of an observed situation. This reflects the impossibility of seeking a whole explanation within any single, pre-paradigmatic discipline. Doubts were also cast on the usefulness of sociological models of marginality, which could not be demonstrated by systematic analysis, as distinct from the use of selective examples. The use of stigmatising mechanisms could be demonstrated. The issue of social control emerged as a multi-faceted negotiating process rather than as a direct two-way struggle between the powerful and the powerless.

This study examined the lived experience of black registrars (medical residents) in a predominantly white academic medical milieu using the case of the University of Cape Town Faculty of Health Sciences, South Africa. It foregrounded this experience by demonstrating how it is circumscribed by notions of race (and racism). Given the centrality of race and thus, whiteness, a select few members of the white academic staff were included as a 'control' group. The study employed Critical Race Theory (CRT) as its overarching theoretical lens. Research confirmed CRT theoretical underpinnings that life experience in race-centred societies is, largely, circumscribed by race (and racism), it also contended that there existed no singular black experience; hence the emergence of the three narratives of black registrar experience at UCT FHS.

This paper focuses on how white, middle class South African mothers, living within a 60-kilometre radius of Cape Town's Central Business District, juggle their childcare and work responsibilities. Through use of multi-sited ethnography, I was able to enter the lives of ten white, middle-class South African mothers aged between early forties to early fifties. The data collected was obtained through participant observation, casual conversations and formal, semi-structured, one-on-one interviews. This minor thesis draws on a body of literature that focuses on the multiple paradoxes mothers' face, such as, the traditional gendered notions of what it means to be a "good" mother, the challenges of time, and coping strategies. This paper explores how the research participants reconstituted their lives after having children. Through an analysis of conversations and field observations this minor thesis demonstrates the everyday circumstances of living through and negotiating daily life as a middle class, white mother in Cape Town, South Africa. In this minor thesis, I aim to demonstrate how parenthood is filled with fears and numerous challenges. The findings make strong case for researching the lives of such women who often suffer in silence.

ENGLISH ABSTRACT: The 1994 election seems to stand as a clear divide between past and present in South Africa. But while it was believed that this election would catapult South Africa into a promising new era of democracy and equality, it has become all too clear that the transition was unfortunately limited to the political sphere. Despite some progress being made in the economic sphere, we still have a visible correlation between race and class – a correlation that certainly stems from the apartheid era, signifying a definite continuity of an era long past. In the social sphere we have also struggled to achieve complete integration. We find that racial categories of old have remained an important part of the ‘new’ South Africa. While we were promised a non-racial country, government policies such as Affirmative Action and Black Economic Empowerment have been a constant reminder of supposed racial differences – signifying another continuity of apartheid. While the post-apartheid period can be summarised as a period of change, we find that it can also be summarised by the continuities of the past. It was found that, specifically in my research area, a rural farmers’ community, the continuities of the past are visible in the everyday structures of society. For my research subjects, white Afrikaners, it was found that the 1994 election proved to be no ‘road to Damascus’ regarding beliefs about the racial other. I found that interracial social interaction is still governed by fixed racial boundaries that are rarely crossed and, if crossed, this is done so conditionally. These boundaries seemed to be reinforced by the active socialisation of a community. While many argue that the post-apartheid period has brought on an identity crisis for white Afrikaners, I found that my research subjects have failed to encounter such a crisis, as they have held on to fixed racial boundaries in an attempt to preserve and protect their identity. We find ourselves in a time where we are urged to move beyond our apartheid past, yet many are unable to do so. But the question remains: given our past, should this come as a surprise to anyone?
AFRIKAANSE OPSOMMING: Die verkiesing van 1994 staan as ‘n duidelike skeiding tussen die verlede en die hede in Suid-Afrika. Maar al is daar geglo dat hierdie verkiesing Suid-Afrika in ‘n belowende nuwe era van demokrasie en gelykheid sou inskiet, het dit al hoe meer duidelik geraak dat die oorgang ongelukkig tot die politieke sfeer beperk was. Ten spyte van vordering in die ekonomiese sfeer, vind ons nog steeds dat daar ‘n sigbare ooreenkoms tussen ras en klas is – ‘n ooreenkoms wat seer seker geërf is vanaf apartheid en dui op ‘n definitiewe voortsetting van ‘n era wat lankal verby is. In die sosiale sfeer sukkel ons ook om volkome integrasie te bereik. Ons vind dat die rasse-kategorieë van ouds steeds ‘n belangrike deel van die ‘nuwe’ Suid Afrika bly. Hoewel ‘n nie-rassige land belowe is, dien regeringsbeleide soos Regstellende Aksie en Swart Ekonomiese Bemagtiging as ‘n konstante herinnering aan sogenaamde rasseverskille – nog ‘n voortsetting van apartheid. Terwyl die post-apartheid tydperk opgesom kan word as ‘n tydperk van verandering, vind ons dat dit ook opgesom kan word deur voortsettings van die verlede. Veral in my navorsingsgebied, ‘n plattelandse boeregemeenskap, het ek gevind dat die voortsettings van die verlede sigbaar was in die alledaagse strukture van die samelewing. Vir my navorsingssubjekte, blanke Afrikaners, is dit gevind dat die 1994-verkiesing geensins gedien het as ‘n ‘pad na Damaskus’ in terme van oortuigings aangaande die ‘ander’ ras nie. Ek het gevind dat interrassige sosiale interaksie steeds regeer word deur gevestigde rasse grense wat selde oorgesteek word, en indien wel oorgesteek, word dit voorwaardelike gedoen. Dit wil voorkom of hierdie grense versterk word deur die aktiewe sosialisering van die gemeenskap. Terwyl baie outeurs argumenteer dat die post-apartheidtydperk ‘n identiteitskrisis vir blanke Afrikaners tot gevolg gehad het, het ek gevind dat my navorsingssubjekte nie so ‘n krisis ervaar het nie omdat hulle vasklou aan gevestigde rassegrense in ‘n poging om hul identiteit te bewaar en beskerm. Ons vind onsself in ‘n tyd waar ons aangespoor word om verby ons apartheid verlede te beweeg, maar steeds is baie mense nie in staat om dit te doen nie. Die vraag bly staan: gegewe ons verlede, kom dit vir enigiemand as ‘n verrassing?

Dyer Island is thought to host one of the most abundant populations of white sharks on the planet; this is often credited to the large (55 – 60,000) Cape fur seal colony at Geyser Rock. Yet relatively little work has ever been produced from the area. This may be attributed to the harshness in its location as a study site, exposed to wind and swell from west to east which limits research periods. This study accounts for over 220 hrs of manual tracking at Dyer Island with a further 68 added from the inshore shallow areas of the bay. Sharks focused their movements and habitat use to reefs or channels that allowed access to Cape fur seals. Movement- Based Kernel Estimates (MKDE) were used to compute home range estimates for shark movements through and around the heterogeneous structures of Dyer Island and Geyser Rock. Inshore two core areas were revealed, one being the major reef system at Joubertsdam and the other at a kelp reef where the tracked shark had fed on a Cape fur seal. At Dyer Island one core area was identified in a narrow channel, ‘Shark Alley’, here a second tracked shark foraged for entire days within meters of rafting Cape fur seals. Rate of Movement (ROM) and Linearity (LI) of tracks were low during daytime and movements were focused around areas such as Shark Alley or other areas close to the seal colony before moving into deeper water or distant reefs with higher rates of ROM and LI at night. If moonlight was strong foraging would take place to the south of Geyser Rock but with higher ROM and LI than observed during the day. Foraging patterns in this study contrast studies from other sites in South Africa and home range and activity areas were comparatively much smaller than observed in Mossel Bay. It has been established that several known white sharks forage at Dyer Island and the other studied aggregation sites, such differences in foraging would suggest that they are able to adapt their foraging behaviour to suit the environment they are in; making them site specific in their foraging ecology. Both satellite and acoustic telemetry are revealing aggregation hotspots of white sharks in South Africa. It is important that such information is used to assist the recovery of the species which has been protected since 1991, yet is rarely considered in planning of coastal developments.

Il presente lavoro di tesi ha avuto lo scopo di valutare l’effetto dell’insorgenza dell’anomalia di destrutturazione, contestuale o meno al manifestarsi dell’anomalia white-striping, su alcune caratteristiche qualitative delle carni. L’anomalia di destrutturazione ha determinato una consistente diminuzione del contenuto di proteine ed un aumento del tenore di umidità. Al contrario, l’aumento del livello di lipidi è associato alla presenza della sola anomalia white-striping, i cui effetti sulla composizione sembrano essere in generale più moderati. Tuttavia, nel complesso, le modificazioni sulla composizione sono più marcate nella parte superficiale, mentre in profondità le differenze sono di entità più limitate. I petti destrutturati sono inoltre dotati di valori di pH ultimo più elevati, soprattutto nella parte superficiale, e non si discostano da quelli osservati per l’anomalia white-striping. Il colore risulta scarsamente modificato, mentre l’analisi rilassometrica (LR-NMR) ha permesso di evidenziare che i petti destrutturati possiedono un’abbondante quantità di acqua extra-miofibrillare, che più facilmente può essere persa durante le fasi di conservazione e trasformazione delle carni. In analogia con quanto osservato per la composizione chimica, tale risultato è particolarmente accentuato nello strato superficiale, mentre nello strato profondo tali modificazioni riguardano solo i campioni affetti da entrambe le anomalie. Pertanto questo studio ha permesso di stabilire che le modificazioni avvengono principalmente nella porzione superficiale del muscolo P. major, dove verosimilmente i processi degenerativi prendono avvio per poi coinvolgere in una seconda fase anche la parte profonda. Inoltre, è stato dimostrato che la presenza di destrutturazione superficiale dei muscoli pettorali comporta complessivamente una modificazione più accentuata della composizione e della distribuzione dell’acqua rispetto alla sola presenza dell’anomalia white-striping.

It is well-established that personality not only affects physical health and longevity, but also mental health and coping mechanisms. One area of limited research is the relationship between cancer pain and personality. This study examined how personality traits affect reported cancer pain severity in older patients (N = 150) receiving outpatient treatment at a comprehensive cancer center. Participants were interviewed regarding their pain severity, personality, affect, and self-efficacy for pain management. Symptom data were collected from the Brief Pain Inventory, while personality data were gathered from the Ten Item Personality Inventory and the Positive and Negative Affect Schedule. Self-efficacy for pain management was collected from the Chronic Pain Self-efficacy Scale. Analyses included descriptives, Chi-square tests, t-tests, stepwise linear regressions, and moderation analyses. The mean age of the sample was 65.38 ± 7.72 years. Seventy-nine percent of the sample was White. Analyses indicated that the average pain was 4.15 ± 2.01 (0-10 scale; with 10 being worst pain), with the sample recording means of 6.53 ± 2.57 and 2.45 ± 2.15 on worst and least pain, respectively. Regression analyses showed extraversion (â = -0.21, p < .01) and openness to experience (â = 0.18, p < .05) to be significant predictors of higher current and average pain severity, respectively. Agreeableness (â = 0.18, p < .05) was found to be a significant predictor of higher self-efficacy for pain management. Conscientiousness and extraversion were significant moderators in the relationship between self-efficacy for pain management and worst pain severity. These findings indicate that different personality types and personal affect may influence reports of pain severity. More empirical research is needed to understand the impact of personality and its relationship with pain severity and self-efficacy for pain management in more diverse and marginalized cancer populations across the age continuum. Finally, the results may be used to design more individualized interventions on pain management, depending on personality type, an application that has never been done in older adults with cancer.
