Many wildlife tourist attractions (WTAs) have negative impacts on animal welfare and species conservation. In the absence of regulation, raising standards requires tourists to create market pressure by choosing to attend WTAs with benefits for wildlife. We surveyed respondents from five countries – China, Australia, Canada, UK, and USA – to quantify how attitudes to captive animals, and towards WTAs’ outputs and standards, may vary with nationality. Our aim was to provide a firm basis for behaviour change interventions to alter current patterns of tourist consumption of WTAs. All respondents agreed on the importance of conservation and animal welfare, but Chinese respondents were twice as likely to believe that WTAs would not be allowed to exist if they were bad for animals, and that WTAs’ promotional materials were reliable indicators of welfare and conservation standards. These findings indicate Chinese respondents had fundamentally similar attitudes to those from the other countries, but differed in how those attitudes were likely to be applied. Chinese tourists may experience more barriers to aligning their actions with their values with respect to WTAs. Removing these barriers may require information campaigns to highlight the lack of regulation, and the unreliability of some WTAs’ promotional materials and tourists’ reviews.  相似文献

Data from the U.S. Department of Commerce Census of Business in 1963, 1972, and 1977 were compared on a state by state basis and by standard metropolitan statistical areas in order to analyze the spatial growth points of the U.S. lodging industry. The results point to major lodging growth areas in the Sunbelt states with central Florida, Las Vegas, Nevada and Hawaii as outstanding nodes of development. Metropolitan lodging growth has taken place in the Sunbelt cities with populations of 100,000 to one million, with above average growth in those cities located in the coastal zone.  相似文献

ABSTRACT

There is growing evidence that nature-based recreation (NBR) during childhood promotes connectedness to nature, which in turn fuels NBR during adulthood. In addition to providing a number of health benefits, NBR participation may enhance leisure satisfaction, an important predictor of happiness and life satisfaction. In this exploratory study, we tested these hypothesised links using a path model with a cross-sectional sample of 224 Brazilian college students, where NBR participation during childhood increases connectedness to nature and NBR participation during adulthood, which in turn promotes leisure satisfaction. The model fit the data well χ2 (2) = 1.924, χ2/df = 0.962 (N = 220, p = .38), CFI = 1.00, AGFI = .978, GFI = .996, and RMSEA = .00, with results showing an indirect positive link between NBR during childhood and leisure satisfaction, and a direct link between NBR during adulthood and leisure satisfaction. The indirect effect of connectedness to nature on leisure satisfaction was also significant: NBR during childhood fostered connectedness to nature, which motivated NBR during adulthood and higher levels of leisure satisfaction. Leisure practitioners can improve people’s leisure satisfaction by promoting engagement in NBR activities across life stages and emphasising connection to nature.  相似文献

This article presents cost effective guidelines to assist hotels of all sizes with the usage of electronic data interchange (EDI) in the Internet e-business era. The evolution of web-based EDI makes it easier for hotels of all sizes to support their business processes with traditional EDI technology, but without the extensive capital outlay in computer hardware and software. This is an attempt to encourage investment in basic EDI technologies before implementing more sophisticated applications. The focus is to allow hotels of all sizes to improve their competitive advantage with successive EDI technological advances.  相似文献

A phenomenological framework guided data collection and analysis of the prevalent influences on attitudes and behaviors of elementary, junior, and secondary school students towards their physically active leisure. Twenty-two students participated in individual in-depth interviews. Parental influence and outdoor play effected choice and level of physically active leisure for elementary students. Opportunities for organized and non-structured physically active leisure and friends were significant for junior students. Academic responsibilities and organized physically active leisure were influential for secondary students. Common threads were parental influence and the belief that the students were too old to start new activities. These findings highlight the importance of providing opportunities in safe environments for children and youth to participate in a variety of structured and non-structured forms of physically active leisure.  相似文献

An examination of marketing literature reveals a surpricing deficiency of articles discussing theoretical applications in marketing. These deficiencies are largely in the area of specific, practical, everyday applied marketing. This article casts the literature into an overall taxonomy of marketing thought and development, highlighting the deficiency. Then the article discusses the deficiency positing reasons for its continued existence. It is thought that such a taxonomy might better help marketers identify critical need areas that might well result in unusually productive findings and advances important to all marketers. EDITOR'S FOOT-NOTE: Reviewers have agreed that marketing has no Taxonomy and needs one, but that a full study and statement would be a Herculean task. The paper published here is presented as a beginning and, as the author himself states, “in the hope to stir controversy, debate, and effort.”  相似文献

We discuss why corruption remains high and show that corruption contributes to the Banking distress and to the rapid transmission across international stock and currency markets. Undeveloped ‘derivative securities’ markets make the risk from stress-induced volatility difficult to manage. Vinod’s (1999) closed economy model is extended to indicate the asymmetry of ‘home bias’ and the effect of corruption on the value at risk (VaR). Our theory predicts that capital flight controls will be many, foreign direct investment (FDI) will be low and cost of capital will be high in corrupt developing countries, which is supported by Asian data. We include some policy recommendations regarding financial institutions and markets.  相似文献
