The research goals of this study were to investigate how transition process activities among flight attendants affect team efficacy. We distributed a total of 600 questionnaires to flight teams in an airline company, which yielded a usable response of 275 fully completed questionnaires in the end. The research model and the hypotheses were tested using a structural equation modeling approach.Our findings suggest that transition team activities have emerged as an important asset in team efficacy; moreover, increasing flight attendants' job satisfaction should be a priority for airline companies. Second, communication between flight attendants requires not just the delivery of information but also receipt and comprehension of the knowledge interchange, third, the development of shared leadership should be concerned in flight teams.  相似文献

On the Second-best Policy of Household's Waste Recycling   总被引:5,自引:1,他引:5  
This study analyzes the second-best household's waste recycling policy. If we assume the first-best economy with no illegal disposal or transaction costs, then unit pricing, an advance disposal fee and a recycling subsidy are required in order to achieve the social optimum such that both the sum of unit pricing and an advance disposal fee and the sum of unit pricing and a recycling subsidy are equal to the marginal disposal cost. Furthermore, the first-best outcome can also be obtained by a producer take-back requirement system.In the real economy, however, various factors prevent the first-best optimal outcome. In this study we consider two factors, one being the transaction cost associated with a recycling subsidy (or refund) and the other being illegal disposal by the consumer. If a recycling subsidy (or a deposit-refund system) is adopted, a transaction cost associated with it will be generated. Alternatively, if unit pricing is adopted, some of the consumed goods may be disposed of illegally. We show the complete trade-off between unit pricing and a recycling subsidy. In other words, we can not adopt unit pricing and a recycling subsidy simultaneously. As a result, there are three candidates for the second-best policy: unit pricing with an advance disposal fee, a deposit-refund system, and a producer take-back requirement system.Which of these three policies is the second-best policy will depend on the relative magnitude of the price of a recycled good and the marginal transaction cost associated with a recycling subsidy (or the refund in a deposit-refund system). Generally, if the price of a recycled good is positive and the marginal transaction cost is relatively high, unit pricing with an advance disposal fee is the second-best policy. However, where the price of a recycled good is negative and the marginal transaction cost is relatively high, a producer take-back requirement system is the second-best policy. Further, where the marginal transaction cost is relatively low, a deposit-refund system is the second-best policy, regardless of whether the price of a recycled good is positive or negative.  相似文献

The impact of human activity on biodiversity is very complicated, making it difficult to design practical indicators for assessment. Currently, state and response indicators are listed within Chapter 15 of Agenda 21, but no mention is made of driving force indicators and how they relate to biodiversity protection. This paper represents an effort to identify and then operationalize the idea of driving force indicators at national level. Five human induced factors affecting blodiversity were discussed: (a) habitat toss and fragmentation; (b) overexploitation of resources; (c) species introduction; (d) pollution; and (e) climate change. From these five factors, a subset was selected to serve as possible driving force indicators: (1) habitat loss, (2) the ratio of exotic species to indigenous ones, and (3) the change in pollution status. Although the three indicators are relatively simple, they cover the most important human impacts on biodiversity and offer the potential for further redefinition and ultimate use within the spirit of biodiversity protection.  相似文献

To solve the problem of illegal landings this article proposes a new tax mechanism based on the regulator's own aggregate catch estimates and ex ante self-reports of planned catch by fishermen. We show that the mechanism avoids illegal landings while ensuring (nearly) optimal exploitation and generating (nearly) correct entry and exit incentives. Finally we simulate the mechanism for the Danish cod fishery in Kattegat to obtain a rough indicator of the size of the tax. It turns out that the average tax payment as a percentage of profit is surprisingly low.  相似文献
