Wildlife tourism is one of the fastest growing tourism sectors worldwide. Across the world the number of tourists seeking close interaction with wildlife in their natural environment is growing. Understanding the interface between visitors (social) and wildlife (environmental) can make a critical contribution to the sustainability of this industry. This study examined wildlife tours in Australia. Questionnaires were posted to wildlife tour operators in Tasmania, Western Australia and Northern Territory, seeking information on the characteristics of tours, and the place of science and monitoring in their business. The results illustrate several similarities between wildlife and ecotourism, suggesting the benefits of increasing education and interpretation, both central features of ecotourism, to enhancing the sustainability of wildlife tourism. For tour operators, interactive activities included feeding, swimming with and touching wildlife, and the level of interaction was identified as high, making it imperative to better define interaction and develop species or group-specific protocols for sustainably managing these interactions. Lastly, this study showed a low level of engagement of scientists in protecting the wildlife of interest to tours. Given the centrality of science to sustainability, mechanisms for increasing this involvement particularly in impact research, through partnerships and other means, are critical for the long term sustainability of this industry. 相似文献

ABSTRACTNowadays, information technology (IT) outsourcing companies face enduring demands to reduce cost while increasing productivity. This pressure leads many IT outsourcing companies to rely on outsourcing arrangements with IT personnel suppliers. In order to maximise efficiency, outsourcing companies have focused on fostering high-performing suppliers through improved collaboration and mutual relations. However, it is very difficult to advance to a long-term partnership using the existing outsourcing process because of insufficient collaboration between IT outsourcing companies and their suppliers. Based on collaboration perspective of supply chain management (SCM), this study identifies the critical success factors for collaborative strategic partnerships and presents an evaluation framework for assessing and managing suppliers. We have developed an organisational process model for Supplier relationship management (SRM)-based collaboration which includes some of the key constructs from the previous studies and interviews with the IT outsourcing industry people. In this study, we will identify four types of strategic suppliers and suggest approaches for improving collaborative relationship between an IT outsourcing company and its partner companies. In addition, to validate the feasibility of the proposed model, we applied it to a well-known Korean IT outsourcing company ‘A’. 相似文献

The paper shows the impact of privatization and liberalization on consumers in the telecommunication sector for 15 EU countries. Policy reforms are summarized by the OECD regulatory indicators (REGREF) that consider the extent of privatization, vertical disintegration, and market entry. After controlling for other country variables, first, a test of the impact of ownership and regulatory changes on consumer prices is given. In the second step, the Eurobarometer data on consumers' satisfaction about quality and prices of the telecommunication service are considered. The analysis confirms the importance of market regulation in reducing prices but minimizes the role played by privatization per se. Overall, the findings offer only mixed evidence, and somehow contradict, the hypothesis that all the reforms work in a similar way across the EU countries. 相似文献
