The growing community concern for the environment, and rising energy costs to consumers, has led many power utility companies to adopt strategies aimed at reducing energy consumption in the home and workplace. These strategies have typically been based on extrinsically regulated pricing mechanisms. Although more intrinsically driven interventions have been examined, they are often complex and expensive to implement due in part to the high level of human interaction involved. This two‐part study suggests simpler more cost‐efficient alternatives to enhancing energy saving. It does this via two separate but related studies that examined the application of self‐determination theory (SDT) and word of mouth (WOM) within online communities. The findings suggest a significant increase in reported energy‐saving behaviors over time supporting the role of SDT. There was also evidence that positive WOM increases satisfaction of the three psychological needs of autonomy, competence, and relatedness, further enhancing energy‐saving behavior. These findings have important implications for marketers in terms of behavior change. 相似文献

We provide a new framework for estimating the systematic and idiosyncratic jump tail risks in financial asset prices. Our estimates are based on in-fill asymptotics for directly identifying the jumps, together with Extreme Value Theory (EVT) approximations and methods-of-moments for assessing the tail decay parameters and tail dependencies. On implementing the procedures with a panel of intraday prices for a large cross-section of individual stocks and the S&P 500 market portfolio, we find that the distributions of the systematic and idiosyncratic jumps are both generally heavy-tailed and close to symmetric, and show how the jump tail dependencies deduced from the high-frequency data together with the day-to-day variation in the diffusive volatility account for the “extreme” joint dependencies observed at the daily level. 相似文献

Since the seminal contribution of Jackson and Wolinsky (J Econ Theory 71(1):44–74, 1996) it has been widely acknowledged that the formation of social networks exhibits a general conflict between individual strategic
behavior and collective outcome. What has not been studied systematically are the sources of inefficiency. We approach this
omission by analyzing the role of positive and negative externalities of link formation. This yields general results that
relate situations of positive externalities with stable networks that cannot be “too dense” in a well-defined sense, while
situations with negative externalities tend to induce “too dense” networks. Those results are neither restricted to specific
assumptions on the agents’ preferences (e.g. homogeneity), nor to a specific notion of stability or efficiency. 相似文献

Tim H. Blessing 《Journal of Leadership Studies》2015,9(2):42-46
Sweeney (2003) has stated that Anselm of Canterbury produced a paradoxical understanding: God is both inaccessible and obvious (p. 17). The current article proceeds analogically from Anselm's works to a consideration of whether Leadership Studies and the Social Sciences in general can access the obvious omnipresence of History. Finding that neither Leadership Studies nor the other Social Sciences can access that which is obvious, it then extends, in an Anselmian paradox, to discuss the inevitable use of History in Leadership Studies. 相似文献

Disclosure and the cost of equity in international cross-listing 总被引:1,自引:1,他引:0

In this paper, we examine the relationship between disclosure level and the cost of equity capital for a sample of international
firms cross-listing on the New York Stock Exchange. Increased disclosure has the potential to reduce information asymmetry,
reduce the cost of financing and increase analyst following. Using an international asset pricing model, we find that listing
firms experience a decrease in both disclosure risk and systematic risk while matching firms do not. Further, we find that
the magnitude of the decrease is related to three types of disclosure: accounting standards; analyst following; and exchange/regulatory
investor protection. Our results suggest that increased disclosure through accounting standards is beneficial to investors
and that disclosure can be accomplished through information intermediaries, e.g., analyst following. For firms with the lowest
levels of disclosure prior to cross-listing, all three types of disclosure appear to be valuable.

Previous studies have indicated that travel satisfaction - the experienced emotions during, and cognitive evaluation of, a trip - can be affected by travel mode choice and other trip characteristics. However, as satisfactory trips might improve a person's attitude towards the used mode, persons may be more likely to use that same mode for future trips of the same kind. Hence, a cyclical process between travel mode choice and travel satisfaction might occur. In this paper we begin to analyse this process—using a structural equation modelling approach on cross-sectional data—for people who engage in walking and cycling for leisure trips in the Belgian city of Ghent. The focus on walking and cycling reflects recent studies indicating that active travel is often associated with the highest levels of travel satisfaction. Results of this exploratory analysis offer tentative support for the idea of a cyclical process: the evaluation of walking and cycling trips positively affects the respondents' attitude towards the respective mode, which in turn has a positive effect on choosing that mode. 相似文献

Nature conservation for future sustainable shorelines: Lessons from seeking to involve the public 总被引:1,自引:0,他引:1
The soft coastline of eastern England is dynamic, with much of it subject to the risk of erosion or flooding. A number of internationally important coastal nature conservation sites are under threat. This paper explores the character and reasoning behind changing coastal management policies and governance practices in England. It reveals how Natural England is tackling these changes, notably with regard to establishing reconstituted nature conservation sites and re-designed coastlines. Such an approach requires the close involvement of policy leaders, agency officers, local maritime authorities and local residents. This paper explains how participatory processes play a critical role in the design of new coastlines that are ecologically and geomorphologically sustainable yet enable local communities to survive and flourish. A case study involving a visioning exercise at Winterton-on-Sea in Norfolk, UK, highlights the many practical difficulties around planning for the uncertain future of internationally important nature conservation sites, and local economies and communities. Future moves toward sustainable coastal alignments will have to involve a wide mix of public and civic bodies, as well as local communities, and will be underpinned by risk-based planning and well-researched adaptation and relocation arrangements. 相似文献

Towards sustainable tourism planning in New Zealand: Monitoring local government planning under the Resource Management Act 总被引:1,自引:0,他引:1
In the light of the increasing pace and scale of tourism activity in New Zealand, the concept of sustainable tourism has become a key ingredient in the nation's tourism strategy. This paper explores sustainable tourism planning in New Zealand at the level of local government, and in particular, focuses on the implementation of the Resource Management Act 1991 (RMA) as a mechanism for achieving sustainable tourism. Using the findings of a survey of Regional Councils and Territorial Local Authorities, the paper explores public sector planning responses to tourism impacts and sustainability concerns in New Zealand. The paper extends the earlier work of Page and Thorn (1997. Towards sustainable tourism planning in New Zealand: public sector planning responses. Journal of Sustainable Tourism 5(1): 59-77; 2002. Towards sustainable tourism development and planning in New Zealand: the public sector response revisited. Journal of Sustainable Tourism 10(3): 222-238), which identified major issues of concern at local council level with regard to tourism impacts and argued the need for a national vision for tourism to ensure that the RMA achieved its original goals. Since then, a national tourism strategy has been published and changes in legislation have further empowered local authorities to further progress the sustainability agenda. This paper examines these developments and the ensuing implications, concluding that significant progress has been made in developing tourism policies at the local level, but that a number of constraints and issues limit the development of New Zealand as a sustainable destination. 相似文献
