This paper presents an application of quantitative network analysis. It examines rural development projects with respect to their structural and politico-administrative dimensions, including power relations, conflicts, multifunctionality and intersectorality. The network structures and relations of comparable IPRD and LEADER projects are analyzed. The LEADER project network is shown to be less hierarchical than the IPRD project network, although the LEADER network is not characterized by significantly simpler procedures or clearer policy content than the IPRD network. Information and contact are significantly greater, and conflict density is significantly lower in the LEADER network. Administrative intersectorality is higher in the IPRD project, while the multidisciplinarity and the multifunctionality are higher in the LEADER project. However, the LEADER project is not perceived as delivering its objectives to a greater extent than the IPRD project. The implications for process-oriented evaluation are discussed.  相似文献

Biodiversity is widely recognized as a valuable natural asset to conserve. Yet biodiversity is often reported to be declining worldwide. Biodiversity measures can help evaluating it and conserving it, but need to be clearly defined and assessed. In this paper, I review several biodiversity measures and develop a new one, all based on a matrix of species-level dissimilarity data. The data can be used in its raw form, regardless of its origin (e.g. studies of morphological traits, DNA hybridization experiments…) or of any graphical representation. Then, I propose a two-step assessment of the measures. First, I assess them in terms of their deviation from a strict additive law determining the contribution of each species to the diversity of the set in an ideal setting. This setting refers to a case where the data exactly determines the hierarchical ordering of the species. Second, I assess the measures based on their compliance with a list of axioms. These axioms reflect basic mathematical properties regarded as desirable for diversity measures, such as their monotonicity in species and dissimilarities. Finally, I show the importance of applying the new quantitative assessment and the axiomatic approach together when selecting a dissimilarity-based diversity measure.  相似文献

自从2008年金融危机以来,美国在采取第一轮和第二轮量化宽松货币政策失效后,又采取了扭曲操作和第三轮量化宽松货币政策来稳定和刺激经济,这一系列货币政策再带来美国经济气温回升的同时也带来了许多其他影响,本文从多角度多方面分析研究美国的量化宽松货币政策对美国经济及国际黄金价格的影响。  相似文献

新制度经济学的一个新的发展方向是将两个不同的研究方向:制度环境和制度结构的分析有机地统一起来.文章介绍了在这一研究思路下国外的有关研究运用非连续结构性替代分析工具,既分析了混合经济组织的制度结构特征,指出了混合经济组织的边界,又分析了产权、契约法、声誉效应以及不确定性等制度环境因素对混合经济组织的影响.  相似文献

This paper examines the ability of balanced pension plan managers to successfully time the equity and bond market and select the appropriate assets within these markets. In order to evaluate both market timing abilities in these balanced pension plans, we extend the traditional equity market timing models to also account for bond market timing. As far as we know, we are among the first to apply this multifactor timing model to investigate equity and bond market timing simultaneously. This performance evaluation has been conducted on two samples of Spanish balanced pension plans, one with Euro Zone and one with World investment focus. This allows us to decompose managers’ skills into three components: selectivity, equity market timing, and bond market timing. Our findings suggest that the average stock-picking ability of pension plans is positive. World schemes tend to have positive bond timing skills, while Euro Zone pension plans are on average not able to time equity or bond markets.  相似文献

This paper presents a methodology for organizing and quantifying the results of environmental scanning exercises. The first step of the methodology is to develop a simple systems model whose components capture the essence of the problem context under study. Then, a scan identifies leads that affect one or more components. The impact a lead may have on a component is rated on a numerical scale for any number of time periods of interest. Lower and upper probabilities are estimated for each impact rating for each time period. Lower and upper expected impact scores are then calculated to provide a range of potential impacts over time. An exponential function is used to aggregate the lower and upper expected impact scores upon a component to produce lower and upper expected component changes. The methodology also allows changes in components to impact other components. The methodology was implemented to explore impacts of demographic and technological change upon the future of human and ecological health in the United States.  相似文献

In Belgium, several cities have been experimenting with ‘free’ public transport based on the concept of a third payer system. This study explores the modal shift potential of this measure for commuters by means of a large-scale survey. The results indicate that there is still a margin for a further modal shift, but in order to make public transport more attractive to car users, the price paid by the commuter should be lowered, the quality and capacity of the public services should be improved and the mobility policy of the companies should be adjusted in favour of public transport.  相似文献
