Before embarking on the development of rural areas or regions it seems necessary to answer the following key questions: what goals of the parties involved can be realized, and where, when and how? To tackle these questions we have developed a ‘roadmap’, as part of an overall sustainable development procedure for physical planning and spatial management in rural areas. The roadmap is a tool for the process manager and the people involved. It helps to find the way in the exploration of the potential social, economic and ecological benefits of developing the area or region. The purpose of using the roadmap is to alleviate doubts about the advantages of cooperating in pursuit of sustainable development. A back-casting approach is applied to create appealing visions of the future and visualize mutual opportunities worth implementing. In this article we first describe the need for this new roadmap. We then describe its use, step by step and in some detail. An example of the exploration process is described and the strengths and weaknesses of the roadmap are discussed.  相似文献

The authors examine antecedents and consequences of environmental stewardship in frontline business-to-business teams. On the basis of data from members of 34 teams organized into regional networks, they demonstrate the differential impact of team environmental stewardship on customer satisfaction ratings and sales. Furthermore, the results reveal lagged individual-level effects of autonomy and supervisory support on environmental stewardship, as well as lagged group-level effects of past performance. Finally, dispersion models of team stewardship differentially moderate antecedent–stewardship relationships. Whereas within-team consensus strengthens the impact of past satisfaction ratings on subsequent stewardship, between-team consensus weakens the negative impact of past sales.  相似文献

When modelling rating transitions as continuous-time Markov processes, in practice, time-homogeneity is a common assumption, yet restrictive, in order to reduce the complexity of the model. This paper investigates whether rating transition probabilities change after the origination of debt. Accordingly, we develop a likelihood-ratio test for the hypothesis of time-homogeneity. The alternative is a step function of transition intensities. The test rejects time-homogeneity for rating transitions observed over 7 years in a real corporate portfolio. Especially 1-year transition probabilities increase over the first year after origination. This time effect suggests that banks should manage their credit portfolios with respect to the age of debt.   相似文献

This paper discusses the role of collaborations in the development and implementation of sustainable livestock farming. The study reflects upon the experiences with two innovative pig farming concepts in the Netherlands that aim to address sustainability-related concerns regarding the economic viability, environmental impact and social responsibility of livestock production. The findings show that collaborations can result in smarter and innovative solutions and provide support in the development of more sustainable farming concepts. The study also shows that collaborations do not safeguard the implementing of these concepts in practice. Pioneers are confronted with higher production costs and the complex context of agricultural policies and regulations. These pioneering efforts are, however, the seeds for change, and the key ingredient for a transition towards more sustainable production. We rely upon their innovations, social networks and learning experiences in the transition towards more sustainable production. Therefore, pioneers need to be protected from market influences and regulatory barriers, and supported by intermediaries when developing novelties for a more sustainable agriculture. The findings emphasize the need for more knowledge exchange and understanding between farmers, policy-makers and researchers to navigate towards a more sustainable agriculture in the future.  相似文献

Interest in supporting local and regional food systems is rising and food hubs have attracted considerable attention among Federal, State, and local policymakers. This study explores the problem of endogenous hub location in fresh produce value chains in the Northeastern United States. To overcome limitations in the literature, we incorporate the effects of economies of scale and production seasonality into our models. Three experimental models are designed to examine the effects of alternatively applying yearly, quarterly, and monthly data on model solutions. We explicitly assess how interactions of scale economies and seasonality influence the structure and spatial attributes of an optimal regional produce aggregation hub system. The three models generate marketed different solutions and in many respects they lead to different conclusions about developing local/regional supply chains. The monthly model allows for production seasonality and actual hub operation cycle frequency and thus leads to more efficient hub solution with rich policy implications.  相似文献
