中国、美国和法国,这几个大经济体都换届了,不少欧盟国家在去年也换届了。现在各国都清楚地知道自己的问题所在,也相应地会出台一些政策。我认为,难的是如何把这些政策真正落实下去,而且是长期实施下去 相似文献

Output targeting and capacity utilization issues are crucial but troublesome tasks for the new airport projects. This study aims to identify the output targets for the new-built airport in Istanbul to be considered operationally efficient when compared to regional and global counterparts and to investigate the utilization rate of input resources. To do that, a novel two-stage approach was proposed. The first stage involves setting output targets using a modified DEA approach and multi-layered perceptron algorithm. Once the output targets are determined individually by these two methods, slack variable analysis of DEA was applied in the second stage to define the input slacks related to infrastructure. Analysis results revealed the passenger, cargo, and aircraft movement targets for each stage of the project. Input slacks were also identified, and possible avenues for input reduction were explored that would enhance capacity utilization. 相似文献

The original airport problem is concerned with the cost sharing of an airstrip among airplanes assuming that one airstrip is sufficient to serve all airplanes. In this paper, we generalize the original airport problem by imposing capacity constraints to consider the situation when one airstrip cannot serve all airplanes and investigate how to share the cost among airplanes. We introduce the sequential equal contributions rule for our problem and show that it coincides with the Shapley value of the corresponding airport game when the worth of a coalition is defined to be the minimum cost of serving all members of the coalition. The sequential equal contributions rule requires each airplane to contribute equally to the cost of a given section of any airstrip as long as the length of the section is less than or equal to its desired length even though the airplane cannot use the airstrip. Each airplane’s contribution is the sum of terms, one for each section of the airstrip whose length is less than or equal to its desired length. We also present an axiomatic characterization of the rule by imposing the axioms of efficiency, the equal share lower bound, smaller-cost monotonicity, and population fairness. 相似文献

3. Conclusion The idea of ecometrics, which it has been the purpose here to begin to explain, has its primary basis in pure science’s sublime
insights into nature. That is its main strength at this point. It has to do largely with what happens and has happened, in
terms of DNA’s energy transformations and information gathering. But where it applies to problems which call for decision
and action, it has also to do with what should happen, in connection with which the timeless aim of pursuit of the sublime
offers an important adjunct. In small compass little more can be done than to present the vision of a quantitative discipline
which can be used to serve this end; even the main outlines suggested for its development may be subject to much revision.
However, the discipline envisaged has great flexibility and scope, and therewith significance and interest. On the practical
side, enlightened control of affairs large and small inheres in its embrace of biological and economic knowledge, making it
of concern alike to the educated private citizen and to responsible managers of the planet. On the theoretical side, illumination
of the mind inheres in such potential understanding of the biosphere, in the perspective of geological time as well as of
day to day living, as the idea may suggest.

Five aspects of Japanese organisational practice are commonly cited as factors in the Japanese ‘economic miracle’. While these are often used to illustrate the human-centred philosophy of Japanese management, closer scrutiny reveals that these ‘ideal’ working practices are rooted in various culturally-dependent, coercive techniques which may be unsuitable for Britain. 相似文献

Today's nurse manager is a leader in the 1990s health care delivery system. Collaborating with managers throughout the organization, the nurse manager calls upon skills and advanced education to carry out functions in the areas of clinical systems management, human resource management, environmental management, and financial management. This article describes this health care management role and presents case studies where collaboration with other disciplines was successful. 相似文献

Free or underpriced curb parking creates a classic commons problem. Studies have found that between 8% and 74% of cars in congested traffic were cruising in search of curb parking, and that the average time to find a curb space ranged between 3 and 14 min. Cities can eliminate the economic incentive to cruise by charging market-clearing prices for curb parking spaces. Market-priced curb parking can yield between 5% and 8% of the total land rent in a city, and in some neighborhoods can yield more revenue than the property tax. 相似文献
