Rethinking social impacts of tourism research: A new research agenda   总被引:2,自引:0,他引:2  
Understanding the social impacts of tourism on communities is extremely important for government at all levels so that action can be taken to reduce the likelihood of a community backlash against tourists and tourism development. Given that the residents of many tourism destinations are a fundamental part of the tourism ‘product’, resident attitudes and behaviour have a sizable impact on the success or otherwise of a destination. Research on the social impacts of tourism on communities is substantial and ongoing and while advances have been made in the area, the research has not addressed some of the deep seated issues faced by tourist destinations. This paper provides a critique of the social impact of tourism literature, highlighting the inadequacies in the research that has been conducted to date, which then leads to the development of a new conceptual framework. The paper traces the key developments in social impact research and argues that the predominance of quantitative methods potentially limits our ability to gain a more in-depth understanding of the impacts and how they influence both the host community and tourists. The paper finds that the quantitative focus from previous social impact research has led to a narrow understanding of the issues surrounding social impacts and proposes a new research agenda based on ‘layers’ of social impact understanding through the use of ethnography or phenomenology. The paper concludes with recommendations to progress social impact research beyond simply describing the issues towards explanations of why they occur by suggesting that social impact research examine, in greater depth, the values and intrinsic characteristics of the host residents.  相似文献

Current guidance in the UK and elsewhere indicate upper and target risk limits for the operation of nuclear plant in terms of individual risk per annum. ‘As low as reasonably practicable’ (ALARP) arguments are used to justify the acceptance or rejection of policies that lead to risk changes between these limits. The suitability of cost‐benefit analysis (CBA) and multiattribute utility theory (MAUT) are assessed for performing ALARP (‘as low as reasonably possible’) assessments, in particular within the nuclear industry. Four problems stand out in current CBA applications to ALARP, concerning the determination of prices of safety gains or detriments, the valuation of group and individual risk, calculations using ‘disproportionality’, and the use of discounting to trade‐off risks through time. This last point has received less attention in the past but is important because of the growing interest in risk‐informed regulation in which policies extend over several timeframes and distribute the risk unevenly over these, or in policies that lead to a nonuniform risk within a single timeframe (such as maintenance policies). The problems associated with giving quantitative support to such decisions are discussed. It is argued that multiattribute utility methods (MAUT) provide an alternative methodology to CBA which enable the four problems described above to be addressed in a more satisfactory way. Through sensitivity analysis MAUT can address the perceptions of all stakeholder groups, facilitating constructive discussion and elucidating the key points of disagreement. It is also argued that by being explicitly subjective it provides an open, auditable and clear analysis in contrast to the illusory objectivity of CBA. CBA seeks to justify a decision by using a common basis for weights (prices), while MAUT recognizes that different parties may want to give different valuations. It then allows the analyst to explore the ways in which different parties might (or might not) come to the same conclusion even when weighting items differently.  相似文献

Belief elicitation is an important methodological issue for experimental economists. There are two generic questions: 1) Do incentives increase belief accuracy? 2) Are there interaction effects of beliefs and decisions? We investigate these questions in the case of finitely repeated public goods experiments. We find that belief accuracy is significantly higher when beliefs are incentivized. The relationship between contributions and beliefs is slightly steeper under incentives. However, we find that incentivized beliefs tend to lead to higher contribution levels than either non-incentivized beliefs or no beliefs at all. We discuss the implications of our results for the design of public good experiments.  相似文献

In spite of the strategic importance of sustainability reporting in current business practice and the resulting increase in research on its value relevance, studies accounting for stakeholder interdependence are scarce. On the basis of the instrumental stakeholder theory, we investigate whether customers have an impact on the value relevance of sustainability reporting. Using a sample of US listed firms, we show that the value relevance of sustainability reporting is affected by customer profile differences, thereby confirming customer–shareholder interdependence. However, customer profile effects are only predominant if firms' profitability levels are low and disappear as profitability increases. Overall, our findings provide a more nuanced understanding of the value relevance of sustainability reporting. Therefore, we offer managers fine‐grained guidance for value relevant sustainability reporting. Copyright © 2014 John Wiley & Sons, Ltd and ERP Environment  相似文献

Idea Competitions (ICs) are becoming a popular mechanism chosen by firms to perform Open Innovation. They are a way to engage with external sources of knowledge such as individual entrepreneurs and small firms who are asked to submit ideas and compete for a prize. However, little is known about the success of ICs as acquisition mechanisms. The researchers conducted interviews in five multinational companies to evaluate the effects of using ICs as an acquisition mechanism. Although still preliminary, the results of this study show that the success of ICs as an acquisition mechanism remains uncertain because their output (i.e. the number of ideas acquired) is often low compared to the input (i.e. the number of ideas submitted) and effort required to run them (e.g. to vet ideas). Across the cases observed, ICs appear to be more successful at identifying and acquiring early-stage ideas, particularly those outside the current business focus. The study shows that ICs deliver other functional benefits such as improved intelligence and public relations and that these need to be considered as part of the evaluation of the IC's success. The paper concludes by discussing the conditions in which ICs are implemented and the implications for Open Innovation theory.  相似文献

Although frontline employees' bending of organizational rules and norms for customers is an important phenomenon, marketing scholars to date only broadly describe over-servicing behaviors and provide little distinction among deviant behavioral concepts. Drawing on research on pro-social and pro-customer behaviors and on studies of positive deviance, this paper develops and validates a multi-faceted, multi-dimensional construct term customer-oriented deviance. Results from two samples totaling 616 frontline employees (FLEs) in the retail and hospitality industries demonstrate that customer-oriented deviance is a four-dimensional construct with sound psychometric properties. Evidence from a test of a theoretical model of key antecedents establishes nomological validity with empathy/perspective-taking, risk-taking propensity, role conflict, and job autonomy as key predictors. Results show that the dimensions of customer-oriented deviance are distinct and have significant implications for theory and practice.  相似文献

The major goals of this study were to identify voters' belief structures about political advertising, develop a scale to measure beliefs, and examine how the identified beliefs are related to overall attitudes toward political advertising. The reliabilities, factor structure, and validity tests indicate that five belief dimensions—information, veracity, cynicism, money politics, and entertainment—have sound and stable properties. The scale demonstrates that voters assess political advertising at the instrumental level (e.g., information, veracity, and entertainment) as well as the institutional level (e.g., cynicism and money politics). The results showed that not all beliefs predicted overall attitudes. Furthermore, the results indicated that political involvement was a significant factor in influencing both beliefs and attitudes. © 2009 Wiley Periodicals, Inc.  相似文献

Detection of structural change is a critical empirical activity, but continuous ‘monitoring’ for changes in real time raises well‐known econometric issues that have been explored in a single series context. If multiple series co‐break then it is possible that simultaneous examination of a set of series helps identify changes with higher probability or more rapidly than when series are examined on a case‐by‐case basis. Some asymptotic theory is developed for maximum and average CUSUM detection tests. Monte Carlo experiments suggest that these both provide an improvement in detection relative to a univariate detector over a wide range of experimental parameters, given a sufficiently large number of co‐breaking series. This is robust to a cross‐sectional correlation in the errors (a factor structure) and heterogeneity in the break dates. We apply the test to a panel of UK price indices.

Using a unique primary dataset for the UK, we estimate the effect of individual teachers on student outcomes, and the variability in teacher quality. This links 7,305 pupils to the individual teachers who taught them, in each of their compulsory subjects in the high‐stakes exams at age 16. We use point‐in‐time fixed effects and prior attainment to control for pupil heterogeneity. We find considerable variability in teacher effectiveness, a little higher than the estimates found in the few US studies. We also corroborate recent findings that observed teachers’ characteristics explain very little of the differences in estimated teacher effectiveness.  相似文献
