Dolphin-watching tourism is growing globally. In developing countries, the typically low environmental awareness of operators and poorly enforced or non-existent regulations exacerbate risks to wildlife. Ecological indicators like behavioural responses are useful to assess wildlife tourism, but obtaining such data is slow and expensive. We modified the Driver–Pressure–State–Impact–Response (DPSIR) framework to rapidly assess the risk of dolphin-watching tourism harming, displacing or causing local extinction to dolphin populations, using human dimension data to complement limited ecological data. We assessed industries at seven dolphin-watching sites in six countries in Asia: Cambodia, India, Indonesia, Malaysia, Thailand, and the Philippines. All sites have reached or almost reached financial saturation except Cambodia and Malaysia. We find high risk to dolphins at the sites in India and Indonesia and intermediate risk at the site in Cambodia. Pending more ecological data, the risk at Thailand, the Philippines, and Malaysian sites might be low. Our analysis also indicates site-specific conservation recommendations for Driver, Pressure and Response. We suggest that the DPSIR framework is useful to assess the risk of a wildlife watching industry, even when the impact is uncertain due to insufficient ecological data.  相似文献

On the day before the 2016 U.S. presidential election, the odds of Hillary Clinton winning the presidency, according to political prediction markets, were above 90%. Surprisingly, Donald Trump won the Electoral College handily. In this study, we examine how movements in specific stock prices foreshadowed the eventual outcome. Specifically, we conduct a series of standard event-study tests focused on pharmaceutical companies, which became a focal point during the presidential campaign. Results show that while stocks of pharmaceutical companies significantly underperformed the market prior to the election, prices substantially increased beginning three days before the election outcome. This increase is both statistically significant and economically meaningful and robust to various event-study methodologies. These results suggest that some sectors of the stock market seemed to anticipate the election outcome.  相似文献

This research aimed specifically to (1) determine the socio-demographic characteristics and travel patterns of British tourists visiting Phuket; (2) identify the main “push” and “pull” travel motivations of British tourists visiting Phuket; and (3) examine the relationship between British tourists’ main “push/pull” motivations and future travel intention to Phuket. Findings revealed that British tourists’ main push motivations were: “to have fun,” “to rest and relax,” and “to escape from daily routine and environment”; while the main pull motivations were: “natural sceneries and landscapes,” “beaches,” and “hospitality and friendliness of the people.” There was also a relationship found between “push/pull” motivations and future travel intention to Phuket.  相似文献

We formulate a model of capacity expansion that is relevant to a service provider for whom the cost of capacity shortages would be considerable but difficult to quantify exactly. Due to demand uncertainty and a lead time for adding capacity, not all shortages are avoidable. In addition, technological innovations will reduce the cost of adding capacity but may not be completely predictable. Analytical expressions for the infinite horizon expansion cost and shortages are optimized numerically. Sensitivity analyses allow us to determine the impact of technological change on the optimal timing and sizes of capacity expansions to account for economies of scale, the time value of money and penalties for insufficient capacity.  相似文献

In an earlier paper, we showed that bilateral exchange rates are important determinants of multinational activity of both the US and Japan and that increases in the bilateral and third‐country exchange rates exert opposing effects on bilateral multinational activity. Furthermore, the signs of the exchange rate coefficients differ between Japan and the US. In this paper, we formulate a three‐country model with coexisting exporters and multinational firms that engage in Cournot competition to rationalize these effects. In this model, we identify two counteracting effects which govern the bilateral and third‐country effects of an exchange rate increase on bilateral multinational activity. Our theoretical framework is flexible enough to explain the Japanese as well as the US patterns of exchange rate effects and it allows us to identify those factors that are responsible for the respective differences.  相似文献

旅游对传统村落的影响研究——以安徽齐云山为例   总被引:4,自引:0,他引:4  
李萍  王倩  Chris Ryan 《旅游学刊》2012,27(4):57-63
旅游影响一直是国内外旅游研究的重要课题,旅游地居民对旅游发展的感知是研究旅游影响的重要途径。此次调查以安徽省黄山市休宁县齐云山为例,采用问卷调查和现场访谈相结合的方式,运用SPSS、CATPACTM等软件对调查结果进行数理统计,从居民与游客角度分析了旅游开发给齐云山居民带来的经济、社会文化、环境的若干影响,以及居民对旅游业所持的态度。文章着重于探讨居民对于因旅游开发所带来的村落影响的感知,以及他们对于当前旅游影响的评测和对未来旅游发展的期待。  相似文献

Individual performance is a building block of organizational success. Not surprisingly, virtually all organizations have in place some type of performance management system. Yet, managers and employees are equally skeptical that performance management adds value; usually, it is seen as a waste of time and resources. We argue that the potential benefits of performance management are not realized because most systems focus exclusively on narrow and evaluative aspects such as performance appraisal. Herein, we offer a broader view of performance management, including discussion of how it differs from performance appraisal. We highlight specific and important benefits of performance management for employees, managers, and organizations. We also describe research-based conclusions regarding how performance management systems should be designed and implemented to realize these benefits. We hope our article will demonstrate that well-constructed performance management systems should not be hated, but rather embraced.  相似文献

Human players in our laboratory experiment received flow payoffs over 120 seconds each period from a standard Hawk–Dove bimatrix game played in continuous time. Play converged closely to the symmetric mixed Nash equilibrium under a one-population matching protocol. When the same players were matched in a two-population protocol with the same bimatrix, they showed clear movement towards an asymmetric (and very inequitable) pure Nash equilibrium of the game. These findings support distinctive predictions of evolutionary game theory.  相似文献
