Additional state intervention harbours the danger of increasing inconsistencies; this is especially true if there is no clear
demarcation of duties between authorities at different levels, as is the case in many spheres within the EC. The plans to
double the size of the EC Structural Fund by 1992 give reason to subject the EC’s agricultural and regional policy interventions
to scrutiny as regards their consistency and compatibility with overall economic goals. 相似文献

Likert scales are widely used in survey studies for attitude measuring. In particular, the questionnaires propagated by the
SERVQUAL approach are based on Likert scales. Though the problem of attitude suggests an ordinal interpretation of Likert
scales, attitude survey data are often evaluated with techniques designed for cardinal measurements. The present paper discusses
the interpretation of scales for attitude measuring and gives a survey of data analysis techniques under the proper ordinal
understanding. 相似文献

The objective of this study is to develop and evaluate an approach for initiating development of a local industrial symbiosis network. By maintaining the broad perspective of industrial symbiosis, which includes both material and energy flow analysis, and also taking into account the internal energy use and possibilities for energy savings, we aim to achieve a better system view that avoids both sub‐optimizations and unhealthy dependencies. The approach is applied to a case based on the cooperation between the forest industry, municipality and energy service company in a small town in southern Sweden. Several possibilities for improving material and energy use by increasing integration were identified. It was concluded that it is important to have a genuine knowledge of the system studied and close contact with the actors involved, since a simple analysis of energy and material flows is not sufficient to decide which solutions might be more advantageous. It is also important to have a flexible system boundary looking at the system from different perspectives and at different levels to find the best uses for existing energy and material streams.

Technological innovation depends on knowledge developed by scientific research. The number of citations made in patents to the scientific literature has been suggested as an indicator of this process of transfer of knowledge from science to technology. We provide an intersectoral insight into this indicator, by breaking down patent citations into a sector-to-sector matrix of knowledge flows. We then propose a method to analyze this matrix and construct various indicators of science intensity of sectors, and the pervasiveness of knowledge flows. Our results indicate that the traditional measure of the number of citations to science literature per patent captures important aspects of intersectoral knowledge flows, but that other aspects are not captured. In particular, we show that high science intensity implies that sectors are net suppliers of knowledge in the economic sector, but that science intensity does not say much about pervasiveness of either knowledge use or knowledge supply by sectors. We argue that these results are related to the specific and specialized nature of knowledge. 相似文献
