Diese übersicht enth?lt eine Aufstellung wichtiger zwischen 6. Oktober und 10. Dezember 2009 von der Europ?ischen Kommission verabschiedeter Vorschl?ge für von Rat und Europ?ischem Parlament zu beschlie?ende Rechtsakte, sowie von Initiativen der Mitgliedstaaten und Entwürfen des Rates im Rahmen des Titels VI des Vertrages über die Europ?ische Union. Zus?tzlich wird auf rechtspolitisch interessante Texte der Europ?ischen Kommission wie zB Grünbücher oder Erfahrungsberichte hingewiesen. Damit soll dem Leser die M?glichkeit gegeben werden, in einem m?glichst frühen Stadium von neuen Entwicklungen im Gemeinschaftsrecht Kenntnis zu erhalten. Die übersicht enth?lt umgekehrt keine Angaben über vom Rat endgültig verabschiedete Texte. Als Fundstelle wird grunds?tzlich die Referenz des Kommissionsdokumentes angegeben (COM, SEC). Soweit nicht anders angegeben, handelt es sich um EG- (und nicht EAG-) Rechtsakte.  相似文献

This article explores the reasons for the introduction of anticorruption agencies of a specific type in Eastern Europe. It is argued that one of the important functions of these agencies—which are stronger on information gathering, coordination and strategy rather than on investigation of concrete cases—is to give to the government some leverage over the anticorruption discourse. Presenting the anticorruption commissions and agencies as (discourse-controlling) instruments gives an answer to the troubling question why governing parties are at all interested in the introduction of such bodies. Apart from instrumentalization in political discourse, anticorruption bodies in Eastern Europe have had other effects as well. As shown in the Baltic case, institutional engineering provides for a brief window of opportunity during which political forces committed to integrity could gain the upper hand. The problem in Eastern Europe, however, is not the lack of such windows of opportunities—it is more the lack of really committed political forces capable of continuous and consistent anticorruption effort.  相似文献

In their article, Tippins and Wittmann articulate a strong position against custody evaluators making specific custody recommendations to the court. This response will focus on my thoughts about their concepts and my belief that recommendations can be useful and appropriate some of the time, even though there may be significant problems with certain types of recommendations and problems with some evaluators.  相似文献

A simple and sensitive method is described for quantitative analysis of chlorpromazine in blood, serum, urine and tissue homogenate. The chlorpromazine cation radical produced by adding perchloric acid and 2,3-dichloro-5,6-dicyano-p-benzoquinone to the sample can be detected by the ESR method at room temperature. The sensitivity limit is 10 ng, that is, 20 μl of the solution containing 0.5 μg chlorpromazine/ml. The time needed for the measurement is within 10 min. The chlorpromazine radical thus produced is very stable; for example, 95% of the radical was observed after 24 h. The advantage of this method is discussed by comparing with the ordinary spectrophotometry which requires the purification of the sample.  相似文献

Although there has been speculation regarding the pervasiveness and nature of judicial decisions regarding life-sustaining medical treatment (LSMT), no attempt has been made to empirically assess their prevalence or the issues they address. An exploratory study utilizing a mail survey of a nationwide random sample (N = 905) of state trial court judges was conducted to provide initial information regarding this decision-making process. Twenty-two percent of the responding judges had heard at least one LSMT case, and judicial review did not appear endemic to particular states. The number of judges hearing LSMT cases dropped from 1975 to 1981 but has increased since then. Three major issues predominate: patient competency, appointment of a surrogate decisionmaker, and resolution of the ultimate issue of forgoing LSMT. Relatively few cases either contested a prior directive's validity or involved imposing sanctions for instituting or forgoing LSMT. Although subject to different interpretations, the results suggest the courts are having a significant impact on certain aspects of the LSMT decision-making process. However, the infrequency with which any one judge is called upon to make an LSMT decision causes concern about the judiciary's ability to respond in a timely and appropriate manner. With their potential for a profound effect on the actions of health care providers, greater attention to this decision-making process is warranted.  相似文献
