In this paper highway traffic flow is formulated as a short-run production function in which traffic volume is the output and traffic density is the variable input. Given this formulation, the ‘uneconomic’ region of production is relevant. Often it is the case that traffic density will exceed the point at which traffic volume is at a maximum; i.e., the marginal product of the variable input is negative. 相似文献

Using a sample of 233 front-line hotel employees, we examined leader–member exchange (LMX), envy, and organizational citizenship behavior (OCB). The results from path analysis support the research model that employees who have a relatively poor working relationship with their supervisor (i.e., low-quality LMX relationship) were more likely to show higher levels of envy than employees who have relatively closer working relationships with the same supervisor (i.e., high-quality LMX relationship). Ultimately, higher levels of envy decreased employee voluntary helping behavior (i.e., organizational citizenship behavior, OCB) toward coworkers. This finding suggests that employees perceiving a poor working relationship with their supervisor committed less voluntary helping behavior toward coworkers than their counterparts. Implications for managers and suggestions for future research are discussed. 相似文献

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

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
