It has been more than 100 years since Thorstein Veblen published The Theory of the Leisure Class (TLC). The book was a scathing attack on the greedy leisure class of his day and described how people used wealth to elevate their social position in society. Surprisingly, few researchers use this book to understand leisure in contemporary society. TLC remains as relevant today as it did when first published. In this essay I elucidate some of Veblen's ideas and show how they shed light on leisure spending, emulation among birdwatchers, our display of books, boundary maintenance and social distance, and environmental destruction.  相似文献

Children with developmental disabilities participate in more solitary, sedentary, and home-based leisure activities than active physical pursuits or community-based activities. Clinical experience suggests that children with less well-recognized developmental difficulties also have compromised leisure experiences; however, this has not been fully investigated. This study engaged 20 school-age children with developmental difficulties in a community-based circus program, designed in collaboration with occupational therapists. The program included activities such as trampolining, trapeze, and acrobatics. Semi-structured interviews with children and parents explored children's leisure experiences both at circus and more broadly. Qualitative content analysis revealed that friendships, having fun, and being physically active were highly valued aspects of leisure. The coaching style and “just right” level of challenge within programs were identified as central to children's engagement and sense of competence. Participating in a supported leisure program such as circus appeared to promote children's engagement in community leisure, at least in the short term.  相似文献

Network science: A Review Focused on Tourism   总被引:1,自引:0,他引:1  
This paper presents a review of the methods of the science of networks with an application to the field of tourism studies. The basic definitions and computational techniques are described and a case study (Elba, Italy) used to illustrate the effect of network typology on information diffusion. A static structural characterization of the network formed by destination stakeholders is derived from stakeholder interviews and website link analysis. This is followed by a dynamic analysis of the information diffusion process within the case destination demonstrating that stakeholder cohesion and adaptive capacity have a positive effect on information diffusion. The outcomes and the implications of this analysis for improving destination management are discussed.  相似文献

Abstract The purpose of this study is to statistically and empirically evaluate the effectiveness of the gun control laws that have been adopted by states and municipalities. States are divided into two groups: states with no restrictions as to gun use and states with restrictions (e.g., waiting periods, license, etc.). Multiple linear regression models are used to evaluate the relationship between the number of gun related deaths in 1990 and sets of determinants which include state laws and regulations governing the use of firearms. The study results indicate that gun control laws have a very mild effect on the number of gun related deaths while socioeconomic variables such as a state's poverty level, unemployment rate and alcohol consumption, have significant impact on firearm related deaths. These findings suggest that any reduction in resources spent on social programs tied to the Crime Bill may be counter-productive.  相似文献

Recent studies have greatly expanded the literature on the effects of exchange-rate volatility on industry-level bilateral trade flows. In this study, we examine the case of the United States and France, applying cointegration analysis to a set of 146 U.S. export and 115 U.S. import industries. We find that the majority of industries show little or no relationship between risk and trade volumes, but that small industries—particularly for exports—show more sensitivity than do large ones. A disproportionate share of industries respond positively to increased volatility, particularly among U.S. importers, suggesting the presence of “risk loving” behavior.  相似文献

While it is necessary that researchers make choices in order to estimate inequality, the reasons for the measurement choices and their impact on inequality estimates have not been widely assessed. This paper uses Canadian data from the 1980s to analyse whether inequality estimates are sensitive to common measurement choices. Seemingly minor technical choices about the treatment of outlying observations, such as the use of top-income coded data, exclusion of very high and low observations, and differences among data sets in the capture of very high observations affect estimates of inequality. Further, the impact of the treatment of outlying observations on inequality estimates are at least as large as the impact of measurement choices of a conceptual nature, such as the income definition and population selection. The sensitivity of inequality estimates to measurement choices, which often remain invisible, affect inferences about the relative degree of inequality at a given point in time among countries and changes over time.  相似文献

An econometric model is estimated to identify determinants of trade imbalance in international message telephone services markets. Results indicate that asymmetric market structure is important in explaining bilateral market imbalances for high income country pairs. For low and high income country pairs, GDP per capita is the dominant cause of traffic imbalances. The findings suggest that telecommunications liberalization policies are effective in reducing distortions in international traffic flows and settlement payments. However, liberalization should be accompanied by developmental programmes that enhance income per capita and telecommunications network investment in developing countries. Such programmes may be effective in providing a more equitable distribution of the gains from telecommunications reform across countries.  相似文献
