This archaeological community-engaged research focuses on locating, recording, photographing, and classifying, rock art (pictographs and petroglyphs) designs within Heiltsuk and Wuikinuxv Nations’ territories. The two areas are on the Central Coast of British Columbia, Canada: River’s Inlet/Owikeno Lake (Wuikinuxv Territory, near Oweekeno village), and Roscoe Inlet (Heiltsuk Territory, near Bella Bella). By listening to stories and visiting rock art locations its deep history and significance can begin to be comprehended. Throughout this research 58 rock art sites were visited and over 900 designs were categorized into nine types. Within this context I consider the feasibility and benefits of digital contrast adjustment of photographs using DStretch, a plugin created for ImageJ, that renders visible faint traces of pigment which can not be seen with the naked eye. Additionally, the potential of underwater archaeology (scuba diving) for the discovery and recording of rock art sites is explored. / Graduate / 0324

Tourism activities set in coastal and marine environments have evolved far beyond the traditional passive leisure experiences of the classic resort holiday. While the traditional beach holiday remains a contemporary mass tourism phenomenon. Marine tourism now extends far beyond beach activities to a wide spread spectrum of activities including scuba diving with over 20 million certified divers worldwide. The tourism product carries both the characteristics of the service product and the characteristics unique to the tourism industry, which makes the tourism product different from physical/ tangible goods. Therefore tourism destinations involve a multiple of industries (e.g. hospitality, transportation, entertainment) that contribute through their value-added activities to the overall competitive position in the marketplace. Tourism value can be seen as a combination of a product’s (destination’s) perceived quality and associated price which a visitor will summarize as the value received. Value in tourism has been seen as a definite option to improve a destination’s competitive edge. Tourism development is about adding value in a way that is consistent with market demand. As tourism value is created within the destination it holds various benefits including that destinations will achieve high market growth and hence become more competitive due to successful value-added programmes. Destinations are winning competitive battles by careful analysis and response to the core values and needs of the segmented travel marketplace. This study was based on four distinct value dimensions developed by Sweeney and Soutar (2001:211) that are termed emotional, social, quality/ performance and price/ value for money. Sweeney and Soutar’s model (2001:211) was examined to determine its appropriateness for an intangible product in the service sector namely scuba diving. Two modifications to Sweeney and Soutar’s model (2001:211) were required for this study. The modifications which were used in this study included perceived risk value which was introduced by Hall, Robertson and Shaw (2001:350) and epistemic value developed by Sheth, Norman and Gross (1991:160). The primary goal of this dissertation was to determine the perceived value of scuba diving tourists at a marine destination. A literature study was undertaken to contextualise Marine Tourism and perceived value since a review of existing literature on perceived value provides insight as to why the value concept is so crucial for the success of marketing researchers. Thereafter an empirical study was undertaken to obtain relevant data for analysis. A nonprobability sampling method namely convenience sampling was used to conduct the survey due to the absence of a structured list of divers visiting Sodwana Bay during this time. A destination-based survey was undertaken at Sodwana Bay from the 29th of March to the 8th of April 2012. Five hundred (500) self-administered surveys where distributed by field workers among scuba divers who were available and willing to complete the questionnaire. Of the 500 questionnaires distributed a total of 402 were completed and could be used for collation of data. Microsoft™ Office™ Excel 2007 was used to capture the data, which was then statistically analysed and processed by means of descriptive statistics using the SPSS 20.0 programme. More specifically, factor analysis and ANOVAs were done to analyse the value created. In order to achieve the goal, the study was divided into two articles. Article 1 aimed to determine the perceived value of a tourism experience, in this case for the scuba diving tourists at a marine destination, namely Sodwana Bay. Results revealed that the demographic profile of the scuba divers, are middle aged Afrikaans speaking men who are well educated, earn a high income, and originate from Gauteng. To examine the factors underlying the value scale, a principle axis factor analysis with oblique rotation (direct oblimin) was undertaken. The twenty-two factor aspects yielded five factors with eigen values greater than 1.0. These factors explained 64% of the variance and were labelled: ‘Emotional value’, ‘Functional value’, ‘Social value’, ‘Perceived risk value’ and ‘Epistemic value’. Twenty-one aspects had loadings of over 0.418, with only one item having a factor loading of 0.251. With the highest mean (3.43) Epistemic value revealed that respondents consider curiosity, acquiring knowledge, providing novelty and broadening knowledge as key in a valued experience. Reliability (Cronbach’s α) was computed to verify the internal consistency of aspects with each factor. All factors with a Cronbach Alpha above 0.63 were deemed acceptable for the purposes of this exploratory study. Bartlett’s test of sphericity was significant (p<0.001) and the Kaiser-Meyer-Olkin measure sampling adequacy (KMO) was 0.874, which are acceptable for the purpose of this study. Article 2 aimed to determine the factors which influence perceived tourism values of scuba divers at a marine destination, namely Sodwana Bay. To achieve this, ANOVAs were developed and correlations were drawn between age, gender, province, income, level of education, marital status, number of times dived, number of nights stayed in the area, travel group size and media (including, websites, shows, friends, radio, T.V., magazines, previous visits and social networks such as Facebook and Twitter). Correlations were discovered between language, province, marital status, income and media (including, websites, shows, friends, radio, T.V., Magazines, Previous visits and Social Networks such as Facebook and Twitter). The perceived values which were rated highest in each case were emotional value, perceived risk value and perceived functional value. Since this is the first study of its kind in South Africa, it can benefit marine destinations all across the country. The perceived values which were rated highest in both articles should be of high priority in marketing efforts for marine destinations, especially where scuba diving activities are taking place. Assessing and understanding these values will help scuba diving destinations to gain a competitive advantage and provide a more tailor-made product which will improve the value experienced. It is recommended that this study is repeated at other diving sites and also various other tourism products to determine difference and/or similarities between tourism values. Marketing strategies can be utilized through the identification of these and various other values which will improve current marketing efforts. / Thesis (MA (Tourism Management))--North-West University, Potchefstroom Campus, 2013.

Le plongeur subit de nombreuses contraintes issues du milieu dans lequel il évolue. La narcose à l’azote par ses effets sur la performance cognitive en fait partie. Elle est impliquée dans de nombreux accidents de plongée sous-marine. Il est donc nécessaire de développer un outil fiable pour évaluer la performance cognitive sous l’eau de manière quantitative, reproductible et indépendante de la subjectivité du plongeur. Ensuite, après validation de cet outil (fréquence critique de fusion du scintillement - CFFF) préciser le rôle des facteurs modulateurs de la narcose en particulier celui de l’oxygène. Nos investigations sont réalisées chez des volontaires sains sélectionnés spécifiquement pour obtenir une population homogène (genre, âge, BMI, condition physique et expérience en plongée). L’analyse de la performance cérébrale est réalisée au moyen de tests psychométriques, d’échelles visuelles analogique et de la CFFF dans différentes conditions (normobarie, plongées simulées et réelles à 30 mètres de profondeur pendant 20 minutes) et avec différents gaz (air et Nitrox 40%). L’effet propre de l’oxygène est appréhendé par l’utilisation de la spectroscopie proche de l’infrarouge (NIRS).Nos mesures confirment d’une part la dégradation progressive de la performance cognitive tant par les tests psychométriques que par la CFFF avec un bon degré de corrélation (Pearson de 0,86 à 0,93) entre eux et d’autre part l’incapacité du plongeur à s’auto- évaluer. L’évolution de la performance cognitive est caractérisée par une amélioration lors de l’arrivée en profondeur d’autant plus marquée que la quantité d’oxygène dans le mélange respiré est importante, suivie par une dégradation qui persiste au moins jusqu’à 30 minutes après le retour en surface, surtout en respiration d’air. L’utilisation de l’imagerie fonctionnelle cérébrale (NIRS) permet d’associer l’amélioration des performances cognitives à une activation cérébrale dépendante de l’oxygène. L’oxygène semble donc être un élément important de la modulation des symptômes de la narcose à l’azote. De manière très cohérente avec la théorie neurochimique de la narcose nous suggérons que l’effet net sur la performance cérébrale dépend d’une balance entre les effets activateurs de l’oxygène et les effets inhibiteurs de l’azote. / During a dive subjects undergo many environmental stressors. Nitrogen narcosis through its effects on cognitive performance is one of them. Narcosis is indeed involved in many scuba diving accidents. It is therefore mandatory to develop a quantitative, reliable, reproducible tool to evaluate underwater diver’s cognitive performance. This tool should not be dependent on diver’s subjectivity. Once this tool (critical flicker fusion frequency - CFFF) is validated, we could then clarify the role of narcosis modulating factors in particular that of oxygen.Our investigations were performed in healthy volunteers specifically selected in a large group of recreational diver to obtain a standard population (gender, age, BMI, fitness and experience in diving). Cerebral performance analysis is carried out using psychometric tests, visual analogic scale and CFFF in different conditions (normobaria, simulated and open-water dives to a depth of 30 meters of fresh or salt water for 20 minutes) and with different gases (air and EANx 40%). The specific effect of oxygen is apprehended by use of near infrared spectroscopy (NIRS).On one hand, our measurements confirm the gradual deterioration of cognitive performance by both psychometric tests and CFFF, which share a good degree of correlation (Pearson from 0.86 to 0.93) and on the other hand diver’s inability to assess themselves.The evolution of cognitive performance is characterized by an improvement when arriving at depth followed by a progressive impairment that persists for at least 30 minutes after surfacing.The more oxygen in the breathing mixture, the better improvement in the early part of the dive and the less impairment in the following measurements are observed. Brain functional imaging (NIRS) allows us to pair the observed cognitive performance improvement with oxygen-dependent brain activation.It seems that Oxygen is an important modulator of the symptoms of nitrogen narcosis. In accordance with the neurochemical theory of narcosis we suggest that the net effect on cerebral performance depends on a balance between the activating effects of oxygen and the inhibitory effects of nitrogen.

Title: Dependence of the air consumption and the position of the body on the selected method of diving kick and swimming speed Objectives: The goal of this work is to find out the relationship between the diver's swimming speed and the air consumption while using two different methods of diving kicks - flutter and frog kick. At the same time, assess the dependence of the position of the body and head on the swimming speed and method of diving kicks. Methods: In this work was used method of collecting data in real conditions by measuring devices and statistical evaluation of collected data. Results: The results are presented by graphs both in the text of this work and in attachment for its large size. The results of all probands are presented in summary graphs and for selected values the degree of association is calculated in tables using the Pearson correlation coefficient. The main result is the confirmation of the reduction of the deviation from the horizontal position when comparing the slow and higher swimming speeds of both flutter and frog kick. The most effective way for a diver to overcome 50 meters below the water surface was determined to be a flutter kick at medium speed (average 0,37 m/s).

Through in-depth interviews, data were collected from scuba divers living in the city of Rio de Janeiro, during the months of January and February of 2008. In order to obtain the expected objectives, the chosen methodology of research was qualitative, with priority of the subject and the subjectivity, using an interpretative approach for the data analysis. The research results confirm some benefits of high-risk sports practice such as flow, self-evolution and communitas. Two additional benefits are presented: the condition of alterity of the ¿underwater world¿, which attributes extraordinany meaning to scuba diving and impacts identity construction, and the scuba ¿buddy¿ practice, that helps to build-up an overall sense of trust to the other. The work is concluded with some managerial recommendations aiming the development of scuba diving industry and related tourism. These above mentioned suggestions include a new industry positioning, integrated marketing communications with specific references to alterity and flow, market segmentation, the creation of gathering spaces and a gradation scale among practitioners. / Este trabalho tem como objetivo explorar o contexto e as emoções relacionadas à experiência do mergulho scuba como atividade hedônica e as condições em que os benefícios oriundos de seu consumo habitual impactam a construção de identidade do praticante. Por meio de entrevistas em profundidade, foram coletados dados junto a mergulhadores scuba residentes na cidade do Rio de Janeiro, durante os meses de janeiro e fevereiro de 2008. Para atingir os objetivos propostos, o método de pesquisa adotado foi qualitativo, com priorização do sujeito e da subjetividade, utilizando-se uma forma interpretativa para análise de dados. Os resultados confirmaram alguns benefícios da prática de esportes de alto risco já pesquisados academicamente como o fluxo, communitas e evolução pessoal. Apresentam-se dois benefícios adicionais: a condição de alteridade do mundo submarino, que atribui significância extraordinária a essa atividade esportiva e impacta a construção identitária dos envolvidos, e a prática de dupla de mergulho, que desenvolve uma confiança generalizada no próximo e serve como referência na definição do indivíduo. Conclui-se o trabalho, fazendo-se recomendações gerenciais com o intuito de beneficiar e desenvolver a indústria e o turismo relacionado a esse esporte. Essas sugestões incluem um novo posicionamento da indústria, comunicação integrada de marketing com menções específicas à alteridade e à experiência de fluxo, segmentação de mercado, criação de espaços de convivência para praticantes e por último, a criação de uma gradação relativa aos diversos níveis de mergulhadores.

Abstract in English, Afrikaans and Sesotho / Scuba diving is a popular marine recreational activity along the eastern and southern coast of Africa. This region is characterised as the East African Marine Ecoregion (EAME) and is known for its richness in marine fauna and flora, including some of the Indian Ocean‟s most diverse and abundant coral reef ecosystems, making it a popular destination for scuba divers. The future of the scuba diving industry has come under threat as a result of environmental, social, political and economic impacts, and there is a need to better understand how these external risks impact on scuba diving tourism businesses in the EAME. Empirical evidence suggests that external risks, both international and domestic, have an effect on the tourism industry as a whole. However, limited research has been conducted on the impact of such external risks on the dive tourism industry specifically. Existing research has also focused extensively on environmental risks rather than on how external risks of a political, economic and social nature affect dive operator sustainability in the EAME. Most studies have also focused on the demand side (divers) as opposed to the supply side (dive operators). In addition, as dive tourists have greater flexibility to change their destination should risks arise, this threatens the success of dive operators in higher risk areas. To address these problems, the primary objective of the research undertaken sought to comprehensively identify the impact of external risks (environmental, economic, social and political) on dive operators in four countries within the EAME from a supply-side perspective. In order to achieve the primary objective, the following secondary objectives were achieved: 1. Identified scuba diving tourism operators in the EAME and their scope of operation. 2. Determined the external risks most relevant to dive operators in the EAME and assessed their level of impact. 3. Compared the individual external risks experienced by each of the countries in the EAME (Kenya, Tanzania, Mozambique and South Africa) using a cross-case analysis. 4. Assessed the perception of dive operators regarding whether external risks would influence a dive tourists decision to travel to the dive operators area of operation in the EAME ii The study consisted of two phases. Phase 1 comprised structured interviews with a select group of dive operators to gain insight into the external risks most prevalent in the scuba diving industry, as well as to assist in developing a quantitative structured survey (Phase 2), which was subsequently completed by dive operators in Kenya, Tanzania, Mozambique and South Africa. Data was imported into SPSS for quantitative statistical analysis. From the primary data collected, the major findings from this study determined that current economic and political risks have the greatest impact on dive operators in the EAME, and this trend is expected to continue. Environmental degradation of coral reefs, while not seen as a threat at present, constitutes a key threat for the near future. The greatest influences expressed in terms of risk categories impacting on dive tourism are domestic economic risks, international economic risks, domestic political risks and international political risks. A cross-case analysis conducted on the four countries concluded that external risks have varying effects within the different countries. Finally, the results indicated that external risks significantly influence a dive tourist's decision to travel to the EAME. By identifying and assessing the external risks that have an impact on dive operators in the EAME, this research contributes to knowledge on the dive tourism industry in the EAME, as well as dive tourism further afield and the wider field of tourism management. The study's findings create awareness of the effect that external risks have on dive operators in the region. A conceptual framework was developed which encompasses external risks in the scuba diving industry. Risk radars, risk maps and colour-coded tables were further outputs this study which can assist businesses, society and economies in responding to current and future threats and crises in a more informative and intuitive way. This can be achieved by implementing risk management strategies to mitigate or reduce exposure to external risks; strengthening stakeholder involvement along the tourism value chain; and stressing the need for government involvement towards the protection of the environment and promotion of small business growth in the region. Future research can include a wider view of the marine tourism industry and other areas of the Blue Economy. / Skubaduik is 'n gewilde mariene ontspanningsaktiwiteit langs die oos- en suidkus van Afrika. Hierdie streek staan bekend as die Oos-Afrika Mariene Ekostreek (East African Marine Ecoregion, EAME) en is bekend vir sy rykheid aan mariene fauna en flora, insluitende sommige van die Indiese Oseaan se mees diverse en welige koraalrif-ekostelsels, wat dit 'n gewilde bestemming vir skubaduikers maak. Die toekoms van die skubaduikbedryf word bedreig weens die impak van omgewings-, sosiale, politieke en ekonomiese gebeure, en daar is 'n behoefte om beter te verstaan hoe hierdie eksterne risiko's skubaduiktoerisme-besighede in die EAME beïnvloed. Empiriese bewyse suggereer dat eksterne risiko's, internasionaal sowel as plaaslik, 'n invloed op die toerismebedryf as 'n geheel het. Beperkte navorsing is egter gedoen oor die impak van sulke eksterne risiko's op spesifiek die duiktoerisme-bedryf. Bestaande navorsing het ook uitvoerig gefokus op omgewingsrisiko's eerder as hoe eksterne risiko's van 'n politieke, ekonomiese en sosiale aard duik-operateur-volhoubaarheid in die EAME beïnvloed. Die meeste studies het ook gefokus op die aanvraagkant (duikers) in teenstelling met die aanbodkant (duik-operateurs). Verder, omdat duiktoeriste meer buigsaamheid het om hulle bestemming te verander indien risiko's voorkom, bedreig dit die sukses van duik-operateurs in hoë-risiko-gebiede. Om hierdie probleme te hanteer is die primêre doel van die navorsing wat gedoen is om op omvattende wyse die impak van eksterne risiko's (omgewing, ekonomies, sosiaal en polities) op duik-operateurs in vier lande in die EAME te identifiseer uit 'n aanbodkant-perspektief. Om die primêre doelwit te behaal, is die volgende sekondêre doelwitte bereik: 1. Skubaduik-toerisme-operateurs in die EAME en hulle operasionele omvang is geïdentifiseer. 2. Die eksterne risiko's wat die relevantste vir duik-operateurs in die EAME is, is bepaal en hulle vlak van impak is geassesseer. 3. Die individuele eksterne risiko's wat deur elkeen van die lande in die EAME (Kenia, Tanzanië, Mosambiek en Suid-Afrika) ervaar is, is vergelyk deur die gebruik van 'n kruisgeval-analise. 4. Die persepsie van duik-operateurs wat betref of eksterne risiko's 'n duiktoeris se besluit sal beïnvloed om na die duik-operateur se operasionele gebied in die EAME te reis, is geassesseer. Die studie het uit twee fases bestaan. Fase 1 het gestruktureerde onderhoude met 'n geselekteerde groep duik-operateurs behels om insig te kry in die eksterne risiko's wat die algemeenste in die skubaduikbedryf voorkom, en om te help om 'n kwantitatiewe gestruktureerde peiling (fase 2) te ontwikkel, wat gevolglik deur duik-operateurs in Kenia, Tanzanië, Mosambiek en Suid-Afrika voltooi is. Data is ingevoer in SPSS vir kwantitatiewe statistiese analise. Uit die primêre data wat ingesamel is, het die belangrikste bevindings van hierdie studie bepaal dat die huidige ekonomiese en politieke risiko's die grootste impak op duik-operateurs in die EAME het, en daar word verwag dat hierdie tendens sal voortduur. Die omgewingsagteruitgang van koraalriwwe, hoewel dit nie tans as 'n bedreiging beskou word nie, is 'n sleutelbedreiging vir die nabye toekoms. Die grootste invloede wat uitgedruk is as risiko-kategorieë wat 'n invloed op duiktoerisme het, is plaaslike ekonomiese risiko's, internasionale ekonomiese risiko's, plaaslike politieke risiko's en internasionale politieke risiko's. 'n Kruisgeval-analise wat op die vier lande uitgevoer is, het bevind dat eksterne risiko's wisselende uitwerkings binne die verskillende lande het. Laastens het die resultate aangedui dat eksterne risiko's 'n duiktoeris se besluit om na die EAME te reis, aansienlik beïnvloed. Deur die eksterne risiko's te identifiseer en te assesseer wat 'n impak op duik-operateurs in die EAME het, dra hierdie navorsing by tot kennis oor die duiktoerismebedryf in die EAME, asook duiktoerisme verder weg en die wyer veld van toerismebestuur. Die studie se bevindings skep 'n bewustheid van die uitwerking wat eksterne risiko's op duik-operateurs in die streek het. 'n Konseptuele raamwerk is ontwikkel wat eksterne risiko's in die skubaduikbedryf omvat. Risiko-radars, risiko-kaarte en tabelle wat volgens kleur gekodeer is, was verdere uitsette van hierdie studie wat besighede, die gemeenskap en ekonomieë kan help om te reageer op huidige en toekomstige bedreigings en krisisse op 'n meer ingeligte en intuïtiewe manier. Dit kan bereik word deur risikobestuurstrategieë te implementeer om blootstelling aan eksterne risiko's te mitigeer of te verminder; belanghebberbetrokkenheid op die toerismewaardeketting te versterk; en om die behoefte vir regeringsbetrokkenheid by die insluit. / Ho sesa tlasa metsi a lewatle ke mosebetsi o tsebahalang haholo wa boithabiso ba lewatle haufi le mabopo a ka botjhabela le borwa ba Afrika.

Ho etsa qeto ya dikotsi tse ka ntle tsa bohlokwa ho tsamaisa ba disesi ho EAME le ho hlahloba boemo ba tsona ba tshusumetso. 3. Ho bapiswa dikotsi tse ka ntle tsa naha ka nngwe ho EAME (Kenya, Tanzania, Mozambique le Afrika Borwa) ho sebedisa dintlha tsa ho hlahloba diketsahalo. 4.

Mokgahlelo wa 1 o ne o ena le dipuisano tse hlophisitsweng le sehlopha se kgethilweng sa basebetsi ba disesi ho utlwisisa dikotsi tse ka ntle tse atileng haholo indastering ya ho sesa, le ho thusa ho ntlafatsa tlhahlobo e entsweng ka bongata (Phase 2), e ileng ya qetella e phethilwe ke basebetsi ba disesi Kenya, Tanzania, Mozambique le Afrika Borwa. Lesedi le ile la kenngwa ka SPSS bakeng sa tlhahlobo ya dipalopalo. Ho tswa leseding la motheho le bokelletsweng, diphuputso tse kgolo tsa thuto ena di bontshitse hore dikotsi tsa moraorao tsa moruo le tsa lipolotiki di na le tshusumetso e kgolo ho ba sebetsang e le basebetsi ba disesi EAME, mme mokgwa ona o lebeletswe hore o tswele pele. Ho senyeha ha tikoloho ya dimela/diphedi tsa lewatle, ha ho sa nkuweng e le tshoso hona jwale, ke tshoso e ka sehloohong bakeng sa nako e tlang. Tshusumetso e matla ka ho fetisisa e hlalositsweng ka mekgahlelo ya dikotsi tse amang tsela ya ho etela dibaka tsa bohahlaudi ke dikotsi tsa moruo wa lehae, dikotsi tsa matjhaba tsa moruo, dikotsi tsa dipolotiki tsa lehae le dikotsi tsa matjhaba tsa dipolotiki. Phuputso e entsweng dinaheng tse nne e qetile ka hore dikotsi tsa ka ntle di na le diphello tse fapaneng dinaheng tse fapaneng. Qetellong, diphello di bontshitse hore dikotsi tsa ka ntle di susumetsa haholo qeto ya mohahlaudi wa ya sesang tlasa lewatle ho etela EAME. Ka ho kgetholla le ho hlahloba dikotsi tse ka ntle tse nang le tshwaetso basebetsing ba disesi EAME, dipatlisiso tsena di tlatsetsa tsebong lefapheng la bohahlaudi ba ho ho sesa tlasa lewatle dibakeng tsa EAME, ha mmoho le bahahlaudi ba ho sesa ka ho phatlalla tsamaisong ya bohahlaudi.
