Social, natural and cultural systems are changing rapidly, influencing the future of Europe's fresh waters. One of the drivers shaping this future is the implementation of the Water Framework Directive. Participatory scenario development is well-suited to the challenges posed by the WFD to develop a long-term view by involving stakeholders. In this paper we analyse the process and results of a series of stakeholder workshops to develop scenarios at pan-European level. Specifically, we aim at analysing the method and results of combining a backcasting methodology and exploratory scenario development process. Four exploratory scenarios (narrative storylines) were developed, in first instance based on a set of existing European scenarios. Results matched expectations; the process produced stories that are complex, integrated, and rich in detail. During the backcasting exercise, four timelines were constructed, each of which took one exploratory scenario as context. The backcasting process established a strong link with the exploratory scenarios by identifying a large number of obstacles and opportunities in the realisation of those timelines. An analysis across all backcasts yielded a list of 15 robust elements, i.e. elements that are potentially effective in all exploratory scenarios. A stakeholder questionnaire showed that overall there was a widespread satisfaction with both the process and the results. Stakeholders were satisfied with the overall methodology and the exploratory scenarios and somewhat more critical on the backcasting exercise and resulting robust strategies. Above all, we hope to have demonstrated that it is conceptually appealing, methodologically feasible, and practically useful to combine exploratory scenario development and backcasting analysis.  相似文献

The country-image discourse model provides an alternative theoretical framework to explain the meaning of country-of-origin (COO) effects. Unlike previous work, this research relies on the key principles underlying semiotics and discourse theory. The model integrates the semantic and pragmatic dimension of COO and provides hypotheses regarding the structure and function of country-images. Empirical verification through structural equation modeling indicates that the data offer substantial support for the proposed internal structure of the country-image construct, such that country-specific cognitions influence affect, which influences conation. Country-related conations also represent the predominant influence on subjects' beliefs, evaluation, and purchase intentions.  相似文献

We consider a dynamic homogeneous oligopoly in which firms set prices repeatedly. Theory predicts that short-run price commitments increase profits and may lead to less price stability. The experiments that we conducted provide support for the first effect and against the second effect when a random ending rule is applied. When a fixed ending rule is applied, we find no significant impact of short-run price commitments on profits and price stability.  相似文献

Over a decade ago Hansen and Schoenheit (1986), in their Journal of Consumer Policy article, concluded that Consumer Affairs Departments (CADs) offer potential for improving organisational performance in the market place and that their transferability to the European context would be warranted. In this article we trace and analyse the development of Consumer Affairs Departments in the United States and the Netherlands on the basis of fourteen case studies. On the basis of a comparative analysis we conjecture that the application of information technology, the application of communication technology, and personnel management style could be considered as major determinants of differences with regard to CADs in the aforementioned countries. We conclude the article with a number of building blocks that organisations may use in preparing their CADs for the decade to come.  相似文献

This paper investigates the value of collective judgments which stem from settings that have not been designed explicitly to elicit the ‘Wisdom of Crowds’. In particular, I investigate information obtained from transfermarkt.de, an online platform where a crowd of registered users assess the value of professional soccer players. I show that forecasts of international soccer results based on the crowd’s valuations are more accurate than those based on standard predictors, such as the FIFA ranking and the ELO rating. When this improvement in forecasting performance is applied to betting strategies, it leads to sizable monetary gains. I further exploit information on the preferences of individual crowd members in order to investigate whether wishful thinking hampers the accuracy of crowd valuations, but fail to find evidence that such is the case.  相似文献

Under Basel II, retail and SME credit (R&SME) receive special treatment because of a supposedly smaller exposure to systemic risk. Most research on this issue has been based on parameterized credit risk models. We present new evidence by applying Carey's (Carey, Mark. “Credit Risk in Private Debt Portfolios.” Journal of Finance 53, no. 4 (1998), 1363–1387.) nonparametric Monte-Carlo resampling method to two banks' complete loan portfolios. By exploiting that a sub-sample of all borrowers has been assigned an internal rating by both banks, we can compare the credit loss distributions for the three credit types, and compute both economic and regulatory capital under Basel II. We also test if our conclusions are sensitive to the definitions of R&SME credit. Our findings show that R&SME portfolios are usually riskier than corporate credit. Special treatment under Basel II is thus not justified. JEL classification: C14, C15, G21, G28, G33.  相似文献

In this paper, we present a strategy for the development of interactive media scenarios to help communicate uncertainties and complexities in coupled human and natural systems. Insights arising from Complex Adaptive Systems theory advocate the need for more adaptive perspectives on natural resources management. For the collaborative exploration of future complexities and uncertainties, participatory scenario development has proven to be a powerful approach. A range of communication strategies with benefits for conveying complexity, however, has not yet been adopted by scenario developers. We present a framework of criteria with which we structurally analyze the benefits of interactive media communication. First, we consider requirements of feasibility, flexibility and stakeholder contributions. Then, we synthesize criteria for the communication of Complex Adaptive Systems. Finally, we set criteria for communicatory clarity and engagement. Using this framework, we review several science communication fields, including landscape visualization, serious gaming and visual analytics. We then develop a strategy for interactive media communication in participatory scenario development, including two work-in-progress examples. This strategy employs mixed media, micro-games and accessible stakeholder contributions in a geo-web context, and is suitable for participatory work in live settings as well as on-line, from a local to a global scale.  相似文献
