The Covenant of Mayors (CM) is the mainstream European movement involving local authorities who voluntarily commit to increase energy efficiency and the use of renewable energy sources within their territories with the aim of reducing CO2 emissions and meet the European Union objectives by 2020. One country that has a greater number of signatories of this agreement is Spain. This article analyzes which factors influence the decision of Spanish local authorities to join the ever‐growing movement. An empirical model is formulated to describe the behavior of Spanish local governments, this being a binary choice model which is a function of various political, economic, and technical factors. Among the prominent factors that influence this decision are population, availability of renewable energy, fiscal and environmental stress, citizens’ political preference, the contagion effect of neighboring municipalities, the existence of covenant coordinators, and finally, economic motivations.  相似文献

This paper examines the instrumental networks established between organized criminals and national politicians. Its major focus centers on the International Brotherhood of Teamsters, the Department of Labor, and the Reagan Administration. We explore the organized crime influence that affected President Reagan's selection of Raymond Donovan as Secretary of Labor. The choice of Donovan resulted in several related investigations into Donovan's association with organized criminals primarily in the construction industry in New Jersey and New York. We explain and critique the investigations thereby establishing the instrumental quality of the networks and the politics of law enforcement. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Abstract: Recent case-law of the Court of Justice on general interest exceptions to the free provision of services has indicated a flexible approach to general interest exceptions involving moral or ethical issues. In contrast, where the general interest exception is relied on in a case which demonstrates predominantly economic issues, it is subject to strict scrutiny, in particular, with reference to the principle of proportionality. The article analyses the Court's case-law and tries to deduce the criteria which now govern the Court's position. It also highlights difficulties which this two-tier approach may excite. The position of the Court of Justice reflects the lack of homogeneous European ethical and moral standards, but it also underlines the predominantly economic character of European integration to date. It is submitted, nevertheless, that divorcing the economic criteria for integration from general ethical considerations will prove an extremely difficult, if not fruitless, task.  相似文献

This study explored the sense of community among women (n = 21) and women with children (n = 30) living in Oxford Houses, with emphasis on how the presence of children might affect the household. Sense of community did not vary between participants with more or less than three months residence. Residents reported very high levels of satisfaction with the home, possibly because of a ceiling effect of little room for increases in their sense of community over time. Participants reported that they were getting along with the children in the home, that mothers could count on babysitting help, and that the children had a positive effect on the household and their own recovery process. This effect did not differ between mothers and non-mothers, suggesting that non-mothers might view the children in the home with a sense of responsibility and sensitivity comparable to that of the mothers. Implications are discussed.  相似文献

The average exclusion probability is a measure of efficiency in paternity testing; it refers to the a priori ability of a battery of tests to detect paternity inconsistencies. This parameter measures the capacity of the system to detect a false accusation of paternity. Traditionally, this average exclusion probability has been estimated as the probability of excluding a man who is not the father by an inconsistency in at least one of the studied loci. We suggest that this criterion should be corrected, as currently the presumed father is excluded when at least three genetic inconsistencies are found with the child being tested, not just one. This change of criterion has occurred because of the use of microsatellite loci, whose mutation rates are much greater than those of the coding genes used previously in paternity studies. We propose the use of the average probability of exclusion for at least three loci (not only one), as an honest measure of the combined probability of exclusion of several loci, and we propose an algebraic expression to calculate it.  相似文献
