Five 44 gallon drums labeled as glycidyl methacrylate were seized by the Australian Customs Service and the Australian Federal Police at Port Botany, Sydney, Australia, in December 2004. Each drum contained a white, semisolid substance that was initially suspected to be 3,4-methylenedioxymethylamphetamine (MDMA). Gas chromatography-mass spectroscopy (GC/MS) analysis demonstrated that the material was neither glycidyl methacrylate nor MDMA. Because intelligence sources employed by federal agents indicated that this material was in some way connected to MDMA production, suspicion fell on the various MDMA precursor chemicals. Using a number of techniques including proton nuclear magnetic resonance spectroscopy ((1)H NMR), carbon nuclear magnetic resonance spectroscopy ((13)C NMR), GC/MS, infrared spectroscopy, and total synthesis, the unknown substance was eventually identified as methyl 3-[3',4'(methylenedioxy)phenyl]-2-methyl glycidate. The substance was also subjected to a published hydrolysis and decarboxylation procedure and gave a high yield of the MDMA precursor chemical, 3,4-methylenedioxyphenyl-2-propanone, thereby establishing this material as a "precursor to a precursor." 相似文献

On 26 July 2017, the Grand Chamber of the European Court of Justice rendered its seminal Opinion 1/15 about the agreement on Passenger Name Record data between the EU and Canada. The Grand Chamber considered that the decision of the Council about the conclusion, on behalf of the Union, of the agreement between the EU and Canada about the transfer and processing of PNR data must be based jointly on Article 16(2) about the protection of personal data and Article 87(2)(a) about police co-operation among member states in criminal matters, but not on Article 82(1)(d) about judicial co-operation in criminal matters in the EU of the Treaty on the Functioning of the EU. The Grand Chamber also considered that the agreement is incompatible with Article 7 on the right to respect for private life, Article 8 on the right to the protection of personal data, Article 21 on non-discrimination and Article 52(1) on the principle of proportionality of the Charter of Fundamental Rights of the EU since it does not preclude the transfer, use and retention of sensitive data. In addition to the requirement to exclude such data, the Grand Chamber listed seven requirements that the agreement must include, specify, limit or guarantee to be compatible with the Charter.The opinion of the Grand Chamber has far-reaching implications for the agreement on PNR data between the EU and Canada. It has also far-reaching implications for international agreements on PNR data between the EU and other third states. Last, it has far-reaching implications for Directive 681 of 27 April 2016 on PNR data. 相似文献

Abstract This article suggests ways to better design, conduct, and interpret evaluations of the effects of housing mobility programs on participants, with emphasis on how to isolate neighborhood effects. It reviews earlier critiques of neighborhood effects research and discusses the key assumptions of housing mobility programs—about the benefits of affluent neighbors, the spatial organization of opportunity for the urban poor, and the meanings of “neighborhood” to residents, researchers, and policy makers. Studying mobility contexts, especially in suburban areas, offers special challenges to researchers. More research is needed that looks at residents’ social ties and uses mixed‐methods approaches. Ethnographic data, in particular, would enhance the validity of the quantitative data that now dominate studies of neighborhood effects. Adding substantially to what we know about the processes or mechanisms—the “how” of neighborhood effects—mixed‐methods approaches would also make research much more useful to policy makers and program managers. 相似文献

For all of their centralized power and undisputed authority, even crisis leaders are susceptible to breakdowns in political communication. This is particularly significant when martial rule or a state of emergency—most effective when of short duration— becomes open‐ended; the sense of urgency no longer prevails. In the initial stage of proclaiming a constitutional emergency it is perhaps easiest to create an atmosphere of crisis and to promote a collective sense of danger. A climate of national fear and insecurity, in turn, enables the constitutional dictator to mobilize broad support even for draconian measures imposed at the expense of individual freedoms. With the prolongation of the emergency, however, and the institutionalization of crisis government, certain immunities to authoritarianism do begin to surface. As suggested by periods of prolonged emergency rule in India and South Korea, the leader becomes remote and isolated; he or she no longer feels quite so compelled to communicate; domestic opposition increases. The experience of President Marcos and the Philippines since 1972 illustrates some of the political dynamics of the modern, permanent “emergency state.” What has happened to the New Society program of reforms should help in understanding the critical link of communication between leaders and their followers under conditions of either real or manipulative domestic political stress. 相似文献
