Neste trabalho é apresentado um estudo sobre a estrutura vertical e massas d\'água presentes na região oeste e norte da Península Antártica. Foram utilizados dados de temperatura, salinidade e pressão (profundidade) coletados por plataformas de coleta de dados (PCDs) fixadas em elefantes-marinhos do sul (EMS) pelo Projeto MEOP-BR, coordenado pela Profª Dra Mônica M. C. Muelbert, no período de fevereiro a novembro de 2008. Estes dados são transmitidos via sistema de satélites ARGOS a uma taxa de 2.91+/-0.25 vezes ao dia, distância média entre cada perfil coletado é de 14.43 +/- 12.28 km resultando em uma resolução espacial de 41.61 km/dia. Estes dados permitiram uma descrição detalhada da estrutura vertical e identificação de massas d\'água durante diferentes meses do ano de 2008. São comparados perfis verticais em diferentes estações do ano em regiões de plataformas de gelo marinho, do Estreito de Bransfield (EB) e norte da Península Antártica (PA), comparados transectos da porção oeste da PA coletados durante o verão e inverno de 2008 e são apresentados transectos através do Mar da Escócia (ME) nos meses de Setembro a Outubro de 2008. Os valores de temperatura potencial coletados estiveram na faixa entre -1.89ºC e 2.32ºC, os valores mínimos estão relacionados a áreas de formação de gelo marinho e os máximos a investidas através da Corrente Circumpolar Antártica (CCA) em mar aberto e em direção as Ilhas Georgia (IGS). Os valores de salinidade possuem variações entre 32.36 e 35.03 psu, estes valores resultam de diferentes processos, sendo os extremos relacionados a regiões de derretimento e formação de gelo marinho, respectivamente. Graças à grande área utilizada pelos EMS para forrageio durante o x período analisado, diversas massas d\'água são identificadas através de diagramas -S, são elas: Água Profunda Circumpolar (CDW), Água de Inverno (WW), Água de Plataforma de Baixa Salinidade (LSSW), Água Superficial Antártica (AASW), Água de Plataforma de Alta Salinidade (HSSW), Água Profunda Circumpolar Superior e Inferior (UCDW e LCDW), Água de Plataforma (SW), Água de Plataforma de Gelo (ISW), Água Profunda Cálida (WDW) e Água Profunda Cálida Modificada (MWDW). / To study the termohaline structure and water masses in the north and west sides of Antarctic Peninsula, 10 southern elephant seals (EMS) were equipped with highaccuracy conductivity-temperature-depth satellite-relayed data loggers (CTDSRDLs) by the MEOP-BR Project in beginning of 2008 at Elephant Island. Here, we show that measurements collected by these long-ranging, deep-diving predators allow oceanic vertical structure and water masses of the Southern Ocean to be mapped in regions and at times of year not sampled by other oceanographic instruments. These data are transmitted by the ARGOS satellite system at a rate of 2.91+/-0.25 times per day, mean distance between each profile collected is 14.43+/- 12.28 km, resulting in a spatial resolution of 41.61km/day. Vertical profiles are compared at different seasons in sea ice platforms regions, Bransfield Strait (EB) and northern tip of Antarctic Peninsula (PA). Are compared transects at the western side of the PA collected during summer and winter of 2008 and are presented transects across the Scotia Sea (ME) in the months of September and October of 2008. The collected potential temperature values were in the range from -1.89º C to 2.32ºC, the minimum values are related to areas of sea ice formation and the maximum amounts to dives through the Antarctic Circumpolar Current (ACC) in the open sea and towards the South Georgia Islands. The salinity values have variations between 32.36 and 35.03 psu, these values result from different processes, being related to melting and formation of sea ice. The large region sampled allowed us to identify during the study period several water masses from -S diagrams, they are: Circumpolar Deep Water (CDW), Winter Water (WW), Low Salinity Shelf Water xii (LSSW), Antarctic Surface Water (AASW), High Salinity Shelf Water (HSSW), Upper and Bottom Circumpolar Deep Water (UCDW and LCDW), Shelf Water (SW), Ice Shelf Water (ISW), Warm Deep Water (WDW) and Modified Warm Deep Water (MWDW).

Purpose: Prescription stimulant use as "cognitive enhancers" has been described among undergraduate college students. However, the use of prescription stimulants among future health care professionals is not well characterized. This study was designed to determine the prevalence of prescription stimulant misuse among students at an academic health sciences center. Method: Electronic surveys were e-mailed to 621 medical, pharmacy, and respiratory therapy students at East Tennessee State University for four consecutive weeks in fall 2011. Completing the survey was voluntary and anonymous. Surveys asked about reasons for, frequency of, and side effects of nonprescription misuse of prescription stimulants. Given the sensitive material, an opportunity to win one of ten $50 gift cards was used as an incentive. Results: Three hundred seventy-two (59.9%) students completed the survey from three disciplines (47.6% medical, 70.5% pharmacy, and 57.6% respiratory therapy). Overall, 11.3% of responders admitted to misusing prescription stimulants. There was more misuse by respiratory therapy students, although this was not statistically significant (10.9% medicine, 9.7% pharmacy, 26.3% respiratory therapy; P = .087). Reasons for prescription stimulant misuse included to enhance alertness/energy (65.9%), to improve academic performance (56.7%), to experiment (18.2%), and to use recreationally/get high (4.5%). Conclusions: Prescription stimulant misuse was prevalent among participating students, but further research is needed to describe prevalence among future health care workers more generally. The implications and consequences of such misuse require further study across professions with emphasis on investigating issues of academic dishonesty (e.g., "cognitive enhancement"), educational quality, and patient safety or health care quality.

This thesis is based on the assumption that the intersection of moral philosophy and practical risk management is a rewarding area to study. In particular, the thesis assumes that concepts, ideas, and methods that are used in moral philosophy can be of great benefit for risk analysis, but also that practices in risk regulation provide a useful testing ground for moral philosophical theories. The thesis consists of an introduction and five articles. Article I is a review article on social and ethical aspects of radiation protection related to nuclear power generation. The paper concludes that four areas of social and ethical issues stand out as central: The first is uncertainty and the influence of value judgments in scientific risk assessments. The second is the distributions of risks and benefits between different individuals, in both space and time. The third is the problem of setting limits when there is no known level of exposure associated with a zero risk. The fourth is related to stakeholder influence and risk communication. Article II discusses ethical issues related to the proposal that doses (or risks) below a certain level should be excluded from the system of radiation protection, without any regard for the number of people exposed. Different arguments for excluding small radiation doses from regulation are examined and a possible solution to the problem of regulating small risks is proposed in the article: Any exclusion of small doses (or risks) from radiation protection ought to be based on a case-by-case basis, with the condition that the expected value of harm remains small. Article III examines what makes one distribution of individual doses better than another distribution. The article introduces a mathematical framework based on preference logic, in which such assessments can be made precisely in terms of comparisons between alternative distributions of individual doses. Principles of radiation protection and from parallel discussions in moral philosophy and welfare economics are defined using this framework and their formal properties analyzed. Article IV argues that the ethical theory of “responsibility-catering prioritarianism” is well positioned to deal with the reasonable requirements in an ethical theory of risk. The article shows how responsibility-catering prioritarianism can be operationalized using a prioritarian social welfare function based on hypothetical utilities. For this purpose, a hypothetical utility measure called ‘responsibility-adjusted utility’ is proposed, which is based on the utility that would normally be expected given circumstances outside of the control of the individual. Article V was written as a response to the Fukushima disaster. Several authors have called the Fukushima disaster a ‘black swan.’ However, the article argues that the hazards of large earthquakes and tsunamis were known before the accident, and introduces and defines the concept of a ‘black elephant,’ as (i) a high-impact event that (ii) lies beyond the realm of regular expectations, but (iii) is ignored despite existing evidence. / QC 20120816

It is widely recognized that human-wildlife conflicts can reduce farmers’ support for long-term species conservation. The subject of human-elephant conflicts is highly relevant in villages around Babati District in North Central Tanzania because of the closeness to Tarangire National Park. The purpose of this study is therefore to examine local farmers’ attitudes toward elephants and the attitudes’ effects on conservation efforts. Primary data was collected through a qualitative approach of semi-structured interviews with twelve farmers in four villages around Babati, with Wildlife Officer Nashon Macokesha at Babati District Council and with Allan Carlson, Nature Conservation Expert at WWF. A thematic analysis was done to make comparisons between the answers from farmers, Macokesha and Carlson. The Theory of Planned Behavior and the Value-Belief-Norm theory were also used to analyze the underlying factors of the farmers’ attitudes.   The results of this study show that around half of the farmers have positive attitudes toward elephants, while the other half think negatively of them. Elephants were identified as the most problematic species and crop-raiding as the most problematic type of human-elephant conflict. The problems that farmers experience do to crop-raiding and other types of human-elephant conflicts include the direct effects of lost livelihood and income and indirect effects like health impacts and security issues. The result also indicates that factors affecting farmers’ attitudes toward elephants include: 1) the proportion of available land affected by elephants, 2) the closeness of farmers’ fields to Tarangire National Park, 3) the lack of compensation, 4) the ability to affect the decision-making concerning the human-elephant conflicts and 5) the information about and knowledge of elephants and their importance. The underlying cause of the human-elephant conflicts is identified to be the spatial overlap of the two species. To prevent human-elephant encounters in the first place, thereby reducing the risk of human-elephants conflicts, better land use planning can be used to avoid settlement and cultivation close to protected areas. Buffer zones can be established around national parks and reserves to reduce the overlap between humans and wildlife. Mitigation through preventive and deterrent methods like lighting fires, making noises, using chili-dung or chili-grease to scare elephants off farmers’ fields can also be used. Another alternative is to switch from growing high-risk crops that elephants prefer to crops like chili or sesame which rarely gets eaten by elephants. / Att konflikter mellan människor och djurliv kan minska bönders stöd för artbevarande åtgärder är välkänt bland forskare. Konflikter mellan människor och elefanter är vitt förekommande i byar i Babati-distriktet i norra Tanzania på grund av närheten till nationalparken Tarangire. Syftet med denna studie är därför att undersöka bönders attityder till elefanter och attitydernas effekter för bevarandeåtgärder. Primärdata samlades in genom ett kvalitativt upplägg med semistrukturerade intervjuer med tolv bönder i fyra byar i Babati, med Wildlife Officer Nashon Macokesha på Babati District Council samt med Allan Carlson, naturvårdsexpert på WWF. En tematisk analys utfördes för att jämföra svaren mellan bönderna, Macokesha och Carlson och the Theory of Planned Behavior samt the Value-Belief-Norm theory användes för att analysera de underliggande orsakerna bakom böndernas attityder.   Resultatet från denna studie visar att ungefär hälften av bönderna har positiva attityder till elefanter, medan den andra hälften har negativa åsikter om dem. Elefanter identifierades som den mest problematiska arten för bönderna och förstörandet av grödor som den mest problematiska typen av konflikt mellan människor och elefanter. Problemen som bönderna upplever till följd av dessa konflikter inkluderar direkta effekter som förlorad inkomst och försämrade försörjningsmöjligheter, men också indirekta effekter som hälso- och säkerhetsproblem. Faktorer som enligt resultaten i denna studie kan påverka böndernas attityder till elefanter innefattar: 1) andelen tillgänglig mark som påverkas av elefanter, 2) närheten från böndernas mark till nationalparken Tarangire, 3) bristen på kompensation, 4) möjligheten att påverka beslutsprocessen gällande konflikten mellan människor och elefanter samt 5) information och kunskap om elefanter och deras betydelse. Den underliggande orsaken till konflikterna mellan människor och elefanter identifieras vara överlappet i användnings­områden mellan de båda arterna. För att förhindra möten mellan människor och elefanter, och därmed minska risken för konflikter, behövs bättre markanvändningsplanering så att bosättning och jordbruk undviks i närheten av skyddade områden. Buffertzoner kan också anläggas runt nationalparker och reservat för att minska överlappet mellan människor och djur. Avskräckande åtgärder, som att tända eldar, göra oväsen, tända chilibriketter eller sätta upp chili-rep, för att hålla elefanter borta från böndernas åkrar kan också användas. Ett annat alternativ är att bönderna byter från att odla högriskgrödor som elefanter föredrar till att odla grödor som chili eller sesam, vilka sällan eller aldrig äts av elefanter.

The tourism industry is becoming increasingly more competitive, making it essential for tourism destinations to understand why tourists travel to specific destinations. Travel motives are seen as important factors affecting tourist behaviour. Understanding the travel motives of tourists is essential information for the development of a tourism product and its marketing strategy. Tourists to different destinations have different internal reasons for doing so, and wish to fulfil certain needs. These needs motivate tourists to choose a certain destination and, therefore, identifying the travel motives of tourists to tourism destinations will help the destination to better target their marketing strategies to tourists with common motives. The aim of this study is to determine the travel motives of tourists to selected national parks in South Africa as well as to determine whether there are differences and/or similarities between these motives. The parks concerned are the Addo Elephant-, Augrabies Falls- and Golden Gate Highlands National Parks. This will assist SANParks in their future marketing efforts and help to better understand why the tourists choose to visit the respective parks. A literature review regarding tourist behaviour was carried out to achieve Objective 1, which was to conduct a theoretical analysis of tourist behaviour. The primary reasons for understanding tourist behaviour are to be able to retain your customer for life, to fulfil the tourists’ needs and to develop better target marketing strategies. To understand tourists’ travel motives better, studying tourist behaviour becomes important. The tourist’s decision-making process (that forms part of the tourism behaviour model) is divided into six stages. These are, awareness of a need; seeking information; evaluation of information; decision making; action or buying and postpurchase evaluation. The tourist behaviour model consists of a number of factors that influence this decision-making process, including internal (for example perception, learning and motivation) and external (for example culture, social class and family) influences as well as personal (race, gender and age) and market-related (climate, economy and government) influencers. The most important influence relevant to this study is motivation. To achieve Objective 2, which was to conduct a theoretical analysis of travel motives of tourists to nature based products, a literature review concerning the travel motives of tourists was carried out. This revealed that a number of different travel motives to tourism destinations have been identified. Internal needs motivate tourists to travel to specific destinations, in the hope of fulfilling these needs. Research on travel motives is based on a number of theories, and some of the important motives that arose were: nature, wildlife, escape, relaxation, education, novelty, socialisation, family recreation and destination attractions. In conclusion, there are similarities as well as differences in the travel motives of tourists to different natural areas. Objectives 3 and 4 included determining the profiles as well as the travel motives of tourists to the selected national parks. Secondary data was used to determine the profiles and travel motives of the tourists. The first section focused on the profiles of the tourists, which proved to be quite similar in all three parks, with minor differences regarding province of residence and the languages spoken. The second section focused on the travel motives of these tourists, and a factor analysis was used to extract six factors from the data. These factors were: relax and socialise, park attractions, nature and wildlife, knowledge-seeking, photography and park activities. The factors of tourists to each park were compared by means of a practical significance test (ANOVA) to determine the differences in travel motives to each park. The results revealed that certain travel motives were more important to certain of the three selected national parks, for example: knowledge-seeking is more important to tourists visiting the Addo Elephant National Park, relax and socialise is more important to tourists visiting the Augrabies Falls National Park, and park activities are more important to tourists visiting the Golden Gate Highlands National Park. By determining the differences and similarities in travel motives to the three selected national parks, the aim of this study was achieved. The results are in agreement with other researchers’ findings that there are a number of travel motives motivating tourists to visit certain destinations, and this study determined that these motives differ from destination to destination. / Thesis (M.Com.

Tourism comprises the world's largest industry, and beaches (marine tourism) are considered as one of the major tourism attractions in the world. Marine tourism includes different aspects such as the ocean, coastal water sports, hotels and restaurants, island and beach resorts, recreation, fishing boat operators, cruise ships and charter yacht companies. One of the main contributors to marine and wildlife tourism in South Africa, is South African National Parks (SANParks), comprising of 21 national parks. Of the 21 National Parks six are marine national parks covering 4004.4 square kilometres namely West Coast, Wilderness, Tsitsikamma, Addo Elephant, Agulhas and Table Mountain National Parks. The two most known Marine National Parks in South Africa are Tsitsikamma and Addo Elephant National Parks: Addo Elephant for the fact that it is the only national park in South Africa hosting the BIG 7, namely elephant, rhino, lion, buffalo, leopard, whales and great white sharks. Tsitsikamma National Park is important as it is the first and oldest Marine National Park in Africa. South African National Parks receive thousands of visitors each year and tourists visiting these parks are a source of revenue for national parks and by determining travel motives, marketing can be undertaken more effectively, and specific factors can be taken into account when the marketing strategies are being planned. The literature review indicated that an understanding of tourist motives is a key aspect in understanding tourist behaviour. If the travel motives of tourists are known to product owners, in the case of South African National Parks, they will assist the product owner with product development as well as its marketing strategy. By understanding tourist behaviour one can understand why tourists buy certain products and why they make certain decisions. Tourist behaviour can be analysed in terms of the purchasing process a tourist goes through when making a decision. Different tourists will have different decision making processes and will have different motives for buying different products and services. To be able to understand how buyers proceed through the decision making process one has to look at the tourist decision–making process which consists of different influences like demographic factors, the marketing mix, internal/ psychological, external/social and situational factors. From the literature review, the following travel motivations theories were identified: Maslow's hierarchy of needs, Murray's classification of needs, Mill and Morrison's needs and wants theory, Push and Pull theories and the Sun lust and Wanderlust theory. It was found in the literature review that there are some travel motives that are found in most of the nature based destinations such as “relaxation and escape”, “learn about nature” and “park attributes” to name but a few. The research, however, also found that travel motives are closely linked to what these destinations offer and it was also found that different marine destinations seem also to have different travel motives. The aim of this study is, therefore, to determine the travel motives of tourists to selected Marine National Parks in South Africa. Secondary data was used to determine the visitor's profile as well as the factor analysis on travel motives. Four hundred and eight questionnaires were administered to the Addo Elephant National Park and 495 to the Tsitsikamma National Park. The data analysis consisted of two parts, the first part was descriptive data and here the profile of the visitors to the two selected marine national parks was discussed. In the second part a factor analysis was conducted. The aim of a factor analysis is to reduce the data and to assist in the interpretation of the data. A factor analysis further describes the variance–covariance relationship among a number of variables in terms of a few underlying but unobservable random quantities, called factors. For this research a principal axis factor analysis with Oblimin with Kaiser Normalisation rotation was performed on the 22 travel motive items. The visitors' profiles for both the parks were quite similar except for the following: The largest percentage of the visitors to Tsitsikamma National Park were Afrikaans speaking and not as in the case of Addo Elephant National Park most tourists were English speaking, The major markets for Addo Elephant National Park, were the Western and Eastern Cape Provinces and for the Tsitsikamma National Park the major markets were Gauteng and the Western Cape Provinces. The factor analysis regarding travel motives revealed the following four factors: Education and knowledge seeking, Relaxation and escape, Park attributes and Family togetherness. A comparison was done regarding the travel motives of tourists to the two national parks to determine if there were any differences. A small to medium effect size was found for “relax and escape” and “education and learning about wildlife”, therefore, a small to medium statistical significant difference were found. This research confirmed that different marine destinations have different travel motives. Therefore, marketers can use this information and focus on individual marketing for each park based on the products they offer. / Thesis (M.Com.

A small to medium effect size was found for “relax and escape” and “education and learning about wildlife”, therefore, a small to medium statistical significant difference were found. This research confirmed that different marine destinations have different travel motives. Therefore, marketers can use this information and focus on individual marketing for each park based on the products they offer. / Thesis (M.Com.

This thesis focuses on relationships of opportunity and constraint among farm workers in the Sundays River Valley (SRV), Eastern Cape Province. Relationships of 'constraint' include those experiences of displacement and forced removal and war, including forced removals by the apartheid state in 1960 and 1970. Relationships of 'opportunity' include the ways in which residents in the SRV have contested their experiences of upheaval and domination, and the formation of a regional sense of place and belonging/ investigate how farm workers actually draw elements of locality and identity from their experiences of upheaval, and how displacement bolsters feelings of belonging and place. Instead of viewing displacement as a once-off experience, this thesis investigates displacement in historical terms, as a long-term, 'serial' experience of human movement, which is continued in the present- specifically through the creation of the Greater Addo Elephant National Park. I concentrate on developing a spatialised and cultural notion of movemenUplacement. 'Place' is investigated as a term that refers to rather indeterminate feelings of nostalgia, memory and identity, which depend on a particular connection to territory (ie: 'space'). I emphasise that elements of place in the SRV are drawn from and expressed along dualistic lines, which juxtapose situations of opportunity and constraint. In this way, farm workers' sense of connection to farms and ancestral territory in the SRV depends on their experiences of stable residency and work on farms, as well as their memories of removal from land in the area. I emphasise that those elements of conservatism (expressed as 'tradition' and Redness) among Xhosa-speaking farm workers are indications of a certain hybridity of identity in the region, which depend on differentiation from other groups (such as so-called 'coloured' farm workers and 'white' farmers), as well as associations between these groups. This thesis lays emphasis upon those less visible and definable 'identities' in the Eastern Cape Province, specifically by shifting focus away from the exhomeland states of the Ciskei and Transkei, to more marginal expressions of identity and change (among farm workers) in the Province. I point out that labourers cannot solely be defined by their positions as farm workers, but by their place and sense of cultural belonging in the area. In this sense, I use the idea of work as a loaded concept that can comment on a range of cultural attitudes towards belonging and place, and which is firmly embedded in the private lives of labourers - beyond their simple socio-economic conditions of farm work. I use Bourdieu's conception of habitus and doxa to define work as a set of dispositions that have been historicised and internalised by workers to such an extent, that relationships of domination are sometimes inadvertently obscured through their apparent 'naturalness'. Moreover, I point out that work can be related to ritualised action in the SRV through the use of performance and practice-based anthropological theory. Both work and ritual are symbolic actions, and are sites of struggle within which workers express themselves dualistically. Rituals, specifically, are dramatic events that combine disharmonious and harmonious social processes - juxtaposing the powerlessness of workers (on farms), and the deep sense of belonging and place in the SRV. I argue that the deep historical connections in the SRV have largely been ignored by conservationists in the drive to establish new protected zones (such as the Greater Addo Elephant National Park), and that a new model of shared conservation management is needed for this Park.
