The international ski tourism industry is highly vulnerable to inter-annual climate variability and climate change. Accordingly, there is a strong need to advance our understanding of climate risk for this multi-billion tourism market that is so important to mountain regions around the world. This study addressed major limitations in the ski tourism literature, while concurrently supporting priority information needs of ski tourism stakeholders. An improved version of SkiSim 2.0 is applied to all 34 alpine ski areas in southern Ontario (Canada) to examine potential changes in the capacity of this regional marketplace. Model improvements include differential snowmaking capacities of individual ski areas, updated snowmaking decision rules, as well as a new indicator, termed ‘terrain-days’, to estimate changes in system capacity. The results project two fundamentally different futures for this ski tourism marketplace under climate change. If the international community succeeds in achieving the?+?2°C Paris Agreement policy goal, then losses in system capacity can be limited to less than 10% in the mid- and late-century. In contrast, a high-end emission scenario (RCP 8.5) would severely disrupt this ski tourism market by mid-century, with system capacity losses between 28% and 73%.  相似文献

Interviews were conducted in Kitchener‐Waterloo, Ontario, at eight different recreation areas. These were classified as either designated or nondesignated recreation areas. The interview was designed to obtain information regarding demographic characteristics of the user, attitudes toward the use of urban recreation areas (both playgrounds and areas that are not designated as recreational in character), reasons for choosing a particular recreation site and what users considered to be part of an ideal recreation area. Information gathered by the interview method was supplemented by a series of observations. Results indicated a significant difference between age and reasons for nonattendance at designated play areas. Differences in use by sex were, however, not significant.  相似文献

In this article, the authors describe the place of econometrics in undergraduate economics curricula in all American colleges and universities that offer economics majors as listed in the U.S. News & World Report “Best Colleges 2010” guide (U.S. News & World Report 2009). Data come from online catalogs, departmental Web sites, and online course syllabi. About one-third of the schools require econometrics of all students majoring in economics, about half require it of none, and a sixth require it of some, but not all, economics majors. Among universities with economics PhD programs and liberal arts colleges, almost all those ranked in the top 10 require it. Below the top 10, there is little correlation between ranking and econometrics requirements. Liberal arts econometrics classes are much more likely to require research projects than their counterparts in universities.  相似文献

Given an increased emphasis on work teams in organizations, it is important to select applicants based on their ability to make contributions to a given work team. This paper proposes that person–group fit should be useful to select applicants for work teams and suggests that effective use of person–group fit will create both more cohesive work units and more effectively functioning work units. It proposes ways to make valid and reliable assessments of person–group fit that could be used to minimize bias in the selection process. Finally, it addresses several implications of using the person–group fit paradigm for human resource management practice. © 2001 John Wiley & Sons, Inc.  相似文献

The authors of this article describe an adaptation of the rent-seeking game by Goeree and Holt (1999) to the recruiting of athletes by NCAA Division I football and basketball teams. Students engage in an effort-based lottery, i.e., recruiting to sign a blue-chip prospect. The winner gets the prize—the player's marginal revenue product in excess of his grant in aid. Students recruit in three scenarios: by recruiting legally, by recruiting legally or with illegal bribes, and by offering wages to athletes in an auction. The authors demonstrate the game's use in a principles course, but it is easily adaptable to other courses. To aid instructors unfamiliar with sports and NCAA recruiting, they include a comprehensive lesson plan with suggested readings and multimedia.  相似文献

Homelessness, despite being a major social policy issue in Australia, is an area that is not well served by data. Most sorely lacking is any large‐scale panel study that follows a broad sample of persons with recent experience of homelessness and unstable housing histories. In 2010, the Australian Government set about rectifying this deficiency when it commissioned the Melbourne Institute to undertake a new panel study, now known as ‘Journeys Home’. This study draws its sample from the population of Centrelink income‐support recipients, targeting persons identified in the administrative data as having recent experience of homelessness, as well as others with similar characteristics who may be vulnerable to housing difficulties in the future. This article summarises the design of this new study and reports on fieldwork outcomes from the first two waves of data collection.  相似文献

This article examines the impact on deterrence of laws that allow the seizure of assets used in the commission of a crime but owned by someone other than the offender. The results suggest that forfeiture can be used effectively, in combination with more standard tools (criminal fines or imprisonment), as a deterrent under certain conditions, but the risk of overuse is real. In particular, complete forfeiture (seizure of the entire value of the asset) is not generally socially optimal, but when enforcers are rent‐seekers who care primarily about the revenue generated by forfeiture, they will use the tool to the maximum extent allowed by law.
