MSc., Faculty of Science, University of the Witwatersrand, 2011 / A selection of southern African bird species were modelled in terms of the probability of these species colliding with or being electrocuted on overhead power lines in South Africa, based on morphological and behavioral factors. Species were included in the model on the basis of internationally recognized vulnerability to these interactions at the family level. The collision model performed poorly when tested against the actual reported mortalities for species contained in the Eskom-EWT Strategic Partnership Central Incident Register CIR)(chi-square of goodness of fit) at the individual species, family and within family levels. The electrocution model performed slightly better at the family, and within family level. Both collision and electrocution models performed better for the physically larger species (and families) and for those species with higher modelled probability of collision or electrocution. As the product of random carcass detection and reporting, the CIR data are biased in various ways. Testing the models against the CIR is therefore equally important for highlighting inadequacies in the CIR, as in the model. A number of new species have emerged as being of high collision (including most importantly African Pygmy Goose, Southern Ground Hornbill, Black-bellied Bustard, Yellow-throated Sandgrouse, Caspian Tern, Hooded Vulture, Bateleur, African Marsh Harrier, Black Harrier, Pink-backed Pelican and Yellow-billed Stork) or electrocution (Southern Bald Ibis) probability in theoretical terms, and will require further investigation to determine their actual probability of interaction. By mapping the combined distributions of those species with high probabilities of collision and/or electrocution mortality, a number of priority high risk geographic areas emerge around the country.

This thesis examines the contribution made by "alternative" tourism towards community development in the provinces of Phuket, Phangnga, and Krabi in southern Thailand. Aside from providing novel, adventurous, and presumably authentic travel experiences, "alternative" tourism promotes forms of community development characterized by equitable distribution of resources, quality of life, and environmental sustainability. Alongside conventional, mass tourism development in southern Thailand, nature-based "alternative" travel activities such as sea kayaking and jungle trekking have grown increasingly popular among foreign tourists and have emerged as measures of diversification within a slowly stagnating regional tourist trade. This study assesses "alternative" tourism along the lines of the tourism industry, tourist, and host perspectives, and addresses three key issues, or themes: "alternative" tourism as a theoretical and practical "alternative" to conventional, mass tourism; the role played by authenticity and ethical concern in distinguishing "alternative travellers" from mass tourists; and "alternative" tourism's contribution to community-based economic, social, and environmental development in southern Thailand. The results of this study are based upon several types of data, including selfadministered surveys, analysis of statistical and other documentary sources, field observations, and interviews with tourists, government officials, company owners, and Thais working in the tourism industry. Three central findings emerge from this research. First, "alternative" tourism in southern Thailand shares many structural and conceptual links with the existing mass tourism industry. Rather than signalling a true departure from conventional, packaged tourism, "alternative" tourism constitutes a regenerative niche in Phuket's mass tourism industry. Second, discrepant expectations of, and levels of desire for, authenticity serve to differentiate categories of "alternative" tourists, many of whom display insensitive behaviour and place inappropriate demands on their Thai hosts. Third, certain forms of "alternative" tourism, such as "mass ecotourism," foster equitable community development, while others, such as backpacking and adventure travel, remain limited as engines of economic development. In addition to discussing theoretical and policy implications, the thesis concludes with a localized model of "alternative" tourism in southern Thailand.

An idea often held in the mainstream society in the United States is a phenomenon of common occurrence between tornadoes and mobile home residences. While such perceptions could be learned from media presentations of tornadic events, a spatial investigation into such events in the Southeastern United States presents other possibilities. A statistical analysis of correlation is used to investigate the nature of relationship of coincidence between the two variables. Counties with relatively high densities of each variable are used for a case study of common geofactors at the micro scale. Results of this research suggest that a regional correlation between the two variables is non-existent. Results of the case study suggest that, while some similarities in geofactors existent between counties with high densities of each variable, no definitive conclusion can be reached with the data used in this study. / Department of Geography
