Surveys of beach visitor motivation in Ireland, Wales, Turkey and the USA indicate that beach awards play an insignificant role in motivation to visit beaches. However, a number of criteria closely identified with awards, notably cleanliness and water quality, are revealed to be very important. Aesthetic and emotional factors such as scenic setting and general ambience, and practical concerns such as proximity and range of activities available are much more important than beach awards in attracting visitors to beaches. The merits of beach awards are critically reviewed and it is concluded that any benefits that might accrue are in areas other than attracting visitors. 相似文献

Wildlife tourism experiences have the potential to positively impact tourists’ awareness, appreciation and actions in relation to the specific wildlife they encounter and the environment in general. This paper investigates the extent of such impact across multiple sites, and uses Structural Equation Modelling to identify factors that best predict positive long-term learning and environmental behaviour change outcomes. Three sets of variables were measured – visitors’ entering attributes (including pre-visit environmental orientation and motivation for the visit), salient aspects of the experience, and short- and long-term learning and environmental behaviour change outcomes. Although attributes such as pre-visit commitment and motivation to learn were among the best predictors of the long-term impact of the experience, there was evidence that aspects of the experience were also important. In particular, reflective engagement which involved cognitive and affective processing of the experience was found to be associated with short- and long-term environmental learning outcomes. The implications for wildlife tourism managers are discussed. 相似文献

The aim of this conceptual paper is to explore the contribution of the British public house (pub) to marginalised sections of the community. There is a long tradition that celebrates the pub's quasi-egalitarian ethos as welcoming people from all walks of life. However, increased financial pressures on the pub sector dictate an evolution in this role, especially towards disadvantaged sections of society. This situation merits further examination by researchers, managers and policy makers. The paper draws on evidence from different traditions of research including management, sociology, history and geography, to develop a conceptual framework highlighting the issues facing these stakeholders in today's business environment. 相似文献

This paper presents and assesses of the contribution of inward FDI to China's recent rapid economic growth using a two stage growth accounting approach. Recent econometric literature focuses on testing whether Chinese growth depends on inward FDI rather than measuring the contribution. Foreign Invested Enterprises (FIEs), often (but not exclusively) are joint ventures between foreign companies and Chinese enterprises, and can be thought of as forming a distinctive subpart of the Chinese economy. These enterprises account for over 50% of China's exports and 60% of China's imports. Their share in Chinese GDP has been over 20% in the last two years, but they employ only 3% of the workforce, since their average labor productivity exceeds that of Non-FIEs by around 9:1. Their production is more heavily for export rather than the domestic market because FIEs provide access to both distribution systems abroad and product design for export markets. Our decomposition results indicate that China's FIEs may have contributed over 40% of China's economic growth in 2003 and 2004, and without this inward FDI, China's overall GDP growth rate could have been around 3.4 percentage points lower. We suggest that the sustainability of both China' export and overall economic growth may be questionable if inward FDI plateaus in the future. 相似文献

The U.S. Department of Transportation (DOT) defines a flight as “delayed” if it arrives 15+ minutes late. The DOT “flight counting” delay definition is used to rank airline/airport service quality. An obvious caveat of counting flight delays is that the duration of delay plays no role in the delay count. The purpose of this article is to propose an aggregate delay measure that is sensitive to the distribution of time delayed among passengers. The importance of this work is that our derived delay measure reflects passenger preferences rather than the arbitrary delay cutoff established by the DOT. We model passengers' preference ordering using the criteria that passengers prefer fewer, shorter, and more equal delay times. 相似文献

Researchers, examining the need to train performance appraisal raters, have typically used a complex rating task with several dimensions. However, results of a recent training survey (Mealiea and Duffy, 1986) showed that a number of Canadian organizations use a simple one-item, global rating of employee performance, and they are satisfied with their rating process. The present study looks at the influence of the rating task and the type of measurement on the relationship between rater training and rater effectiveness. Subjects were 105 (approximately 50 per cent female and 50 per cent male) patrons of a tavern in upstate New York who served as contestants in a contest of belly button beauty. Four judges, randomly selected from the audience, served over a three week period. Interrater reliability was assessed using a version of the intraclass correlation coefficient, and the Spearman Brown formula was used to estimate the mean reliability of the four judges. The results indicated an absence of leniency and central tendency bias and high interrater reliability without benefit of training. During the three weeks of the study, the average interrater reliabilities were .85, .99, and .99, respectively. The results, as hypothesized, extend the rater training and measurement literature and can be most parsimoniously explained by adding a contingency factor of task/scale characteristics to the rater training effectiveness theory. Résumé Les chercheurs qui ont examiné le besoin de formation pour les évaluateurs de performance ont toujurs utilisé une tǎche d'évaluation complexe au cours de laquelle plusieurs dimensions étaient évaluées. Cependfant les résultats d'un sondage récent (Mealiea et Duffy, 1986) ont démontré qu'un grand nombre d'entreprises canadiennes utilisent un système global à composante unique pour l'évaluation de la performance et sont satisfaits de cette méthode. La présente étude évalue l'influence de la tǎche d'évaluation et le type de mesure sur la relation entre la formation de l'évaluation et son efficacité. Les sujets de cette étude étaient formés de 105 clients (moitié hommes et moitié femmes approximativement) d'un bar de l'état de New York qui participaient à un concours de beauté ombilicale. Quatre juges choisis au hazard dans la salle ont servi pendant une période de trois semaines. La fiabilité a été évaluée à l'aide d'une version du coefficient de correlation interclasse et la formule Spearman Brown a été utilisée pour estimer la fiabilité moyenne des quatre juges. Les résultats ont démontré l'absence de laxisme et de préjugé à tendance centrale et une fiabilité relative élevées des évaluateurs. Pendant les trois semaines de l'étude, les moyennes de fiabilité étaient de .85, .99, et .99 respectivement. Les résultats, tel que prévu confirment les ouvrages concernant la formation et l'évaluation des évaluateurs et peut ětre expliquée avec grand parcimonie en ajoutant un facteur de contingentement de caractéristiques tǎche/ échelle a la théorie d'efficacité de formation de l'évaluateur. 相似文献

On-line supervision exhibits in many respects properties complementary to those of established off-line safety tests. Thus, on-line methods are powerful tools for increasing the safety of chemical processes, especially in situations where unexpected hazards could occur. Known on-line supervising methods are described and their advantage and disadvantages are briefly discussed. The abilities of various on-line methods are demonstrated on a real case. 相似文献

A model is described which includes a taxonomy of the power-motive profiles of individuals-a taxonomy of situational types based upon power considerations and a conceptual link among organizational structure, power-situation type, and individual power motives. The model provides a theoretical connection between micro and macro theories of organizational behaviour and adds some clarification and system to nPow theory. Résumé Le modèle décrit inclut la taxonomie des caractéristiques d'attraction au pouvoir des individus-une taxonomie de situations diverses fondée sur des considérations relatives au pouvoir et sur le lien conceptuel reliant la structure organisationnelle, le type de pouvoir découlant de la situation, et les motivations individuelles. Ce modèle prouve le lien théorique entre les théories micro et macro-économiques du comportement organisationnel, et clarifie et systématise la théorie nPow. 相似文献
