This paper reconsiders the importance of the sovereign state in contemporary geopolitics. The role of the state in an era of globalisation and devolution is a concern that has gained considerable attention in recent geographical scholarship. What has received less attention is how the state has historically functioned as a device that conflated the linked concerns of sovereignty and territoriality. The authors argue that there exist a number of “sovereignty paradoxes” that inhibit the interdisciplinary analysis of the interrelations between sovereignty, territoriality, and state power. Thus, reconsidering sovereignty and territoriality informs both how the state emerged as an important unit of geographical analysis historically, and why the state has become such a problematic concept in contemporary geopolitics. This work has implications for understanding popular struggles over civil liberties, foreign policy, and justice for indigenous peoples. 相似文献

Both quantity of horses and quality stimulate demand for horse race gambling. This paper addresses the potential for a quantity/quality tradeoff due to breeding incentives for California thoroughbreds. Econometric analysis is used to assess the demand for quality and quantity of horses, and results suggest the likely net benefit of breeding incentives on the industry at large. 相似文献

AbstractNational parks in Canada operate under the dual mandate of conservation and visitor use, which involves balancing ecological integrity and nature-based tourism activities. Climate-induced environmental change may increase the existing tension between conservation and visitor use as major tourism resources located in protected areas (PAs) are projected to undergo large-scale changes. This study draws upon the behavioural approach, scenario planning, and landscape visualizations to examine the relationship between climate change impacts, visitor perceptions, and visitor experience management at the Athabasca Glacier in Jasper National Park, Canada. Four tourism development scenarios defined by two management drivers (ecological integrity and visitor demand) with corresponding storylines and visualizations were developed for 2050. The visualized scenarios were presented to visitors (n?=?304) in a survey to understand potential implications on visitor satisfaction. The results suggest that park managers need to find a balance between ecological integrity and visitor use in a way that ensures commercialized tourism development is limited, educational material is prioritized, and ecological integrity is maintained. While understanding the behaviour of future tourists is complex, it is a critical component of climate change adaptation planning and decision-making processes that needs to be prioritized by policymakers and PAs managers. 相似文献

AbstractThe Olympic Games is a major stimulus for increased tourism. In recent years, there have been greater calls for this and other mega-events to leave sustainable positive legacies for the host city, partly to offset the massive cost of hosting. To date, little consideration has been afforded to the role corporates might play in contributing to event legacies. This gap is compounded by the lack of research examining stakeholder engagement in legacy planning more generally. This paper adopts Holmes, Hughes, Mair and Carlsen’s (2015) sustainable event legacy timeline to conceptualise how corporates through the corporate social responsibility (CSR) initiatives of sponsorship and employee volunteering can engage across the Olympic event planning cycle to generate volunteering legacies. Drawing upon a comparative study of the Sydney 2000 and London 2012 Olympic Games, tentative evidence of corporate engagement was noted but for the most part it was fragmented and CSR initiatives primarily focused on the immediate planning and delivery stages of the event cycle. The paper advances new knowledge of how volunteering legacies can be generated through the best practice engagement of corporates as key stakeholders involved in legacy planning and governance across the Olympic planning cycle. 相似文献

Behavioral Adaptation of Alpine Skiers to Climate Change: Examining Activity Involvement and Place Loyalty 总被引:1,自引:0,他引:1
This study employed a visitor survey to analyze the influence that changing climatic conditions have on the substitution behaviors of alpine skiers (activity, spatial, temporal). It further focuses on the role that activity involvement plays in influencing behavioral adaptations (i.e., substitution) and also the extent to which place loyalty is affected. The Modified Involvement Scale (MIS) was used to segment respondents based on high, medium, and low levels of leisure involvement with activity. Highly involved skiers were more likely to change their skiing behavior as a result of poor snow conditions than were less involved individuals. Pritchard's Psychological Commitment Index (PCI) provided evidence that less involved skiers exhibit lower levels of commitment to particular service providers than do highly involved individuals. 相似文献

The martingale hypothesis is tested for 15 European emerging stock markets located in Croatia, the Czech Republic, Estonia, Hungary, Iceland, Latvia, Lithuania, Malta, Poland, Romania, Russia, the Slovak Republic, Slovenia, Turkey and the Ukraine. For comparative purposes, the developed stock markets in Greece, Portugal and the UK are also included. Rolling window variance ratio tests based on returns and signs and with wild bootstrapped p-values are used with daily data over the period beginning in February 2000 and ending in December 2009. The fixed-length rolling sub-period window captures changes in efficiency and is used to identify events which coincide with departures from weak-form efficiency and to rank markets by relative efficiency. Overall, return predictability varies widely. The most efficient are the Turkish, UK, Hungarian and Polish markets; the least efficient are the Ukrainian, Maltese and Estonian stock markets. The global financial market crisis of 2007–2008 coincides with return predictability in the Croatian, Hungarian, Polish, Portuguese, Slovakian and UK stock markets. However, not all markets were affected: the crisis had little effect on weak-form efficiency in stock markets located in Greece, Latvia, Romania, Russia and Turkey. 相似文献

We test the extent and determinants of bias effects of the arithmetic as well as the geometric mean estimator and the estimator of Cooper [1996. Arithmetic versus geometric mean estimators: Setting discount rates for capital budgeting. European Financial Management 2 (July): 157–67] regarding discount rate estimation for firm valuation by way of a bootstrap approach for 13 different countries. The Cooper estimator is superior to both the geometric and the (conventional) arithmetic mean estimator. However, a ‘truncated’ version of the arithmetic mean estimator leads generally to better estimation outcomes than the Cooper estimator. This means that, in order to reduce problems of upward-biased firm value estimates, expected cash flows beyond a certain time horizon are completely neglected in terminal value estimation. Such an approach seems particularly reasonable for the valuation of young growth companies as well as for companies from quickly developing countries such as Brazil, China, or Thailand, because the bias in terminal value estimation is increasing in the growth rate of future expected cash flows. 相似文献

This paper adopts an internet‐based experiment to investigate whether and how individual donors use nonprofit organizations’ financial and nonfinancial information when making their donation decisions. Using undergraduate students in the United States (US) to proxy for individual donors, our results indicate that individual donors are more likely to acquire nonfinancial information, such as nonprofit organizations’ goals, outcomes, programs and missions, than financial information. Donors integrate nonfinancial information into their decisions as their actual donations are significantly correlated with such information. Our results also indicate that while individual donors acquire financial efficiency measures, including the program expense ratio and fundraising expense ratio, they do not seem to integrate such information into their decisions as their actual donations are not significantly correlated with the efficiency information. This study contributes to the nonprofit literature and research domain focusing on charitable giving and donor preferences. 相似文献
