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

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

The 2010 British election resulted in what the British refer to as a “hung Parliament” for the first time in over a generation. This result further heightened the debate over the fairness and utility of the nation’s centuries-old first-past-the-post (FPTP) system. Survey data are used to simulate the election outcome under four different electoral systems beyond FPTP: round-robin pair-wise comparisons, the Borda count, the alternative vote, and Coombs' method. Results suggest that in 2010, the Liberal-Democrats were Condorcet preferred to all other parties and would have won a national election under every tested method except the alternative vote, the method supported by the Liberal-Democrats during the referendum in May 2011 and, of course, FPTP as actually used.  相似文献

The key tenets of neo-liberalism regarding risk, governance, and responsibility are critically evaluated through an empirical study of the private insurance industry. Recent tendencies in this industry towards increasing segmentation of consumers regarding risk, and towards an expansion of private policing of insurance fraud, are analysed. The definition of moral hazard is broadened to include all parties in the insurance relationship, not just the insured. Moral hazards embedded in the social organization of private insurance lead to various kinds of immoral risky behaviour by insureds, insurance companies, and their employees, and to intensified efforts to regulate this behaviour. The analysis concludes with some critical observations about the neo-liberal emphasis on minimal state, market fundamentalism, risk-taking, individual responsibility, and acceptance of inequality.  相似文献

Objectives

We provide a critical review of empirical research on the deterrent effect of capital punishment that makes use of state and, in some instances, county-level, panel data.

Methods

We present the underlying behavioral model that presumably informs the specification of panel data regressions, outline the typical model specification employed, discuss current norms regarding “best-practice” in the analysis of panel data, and engage in a critical review.

Results

The connection between the theoretical reasoning underlying general deterrence and the regression models typically specified in this literature is tenuous. Many of the papers purporting to find strong effects of the death penalty on state-level murder rates suffer from basic methodological problems: weak instruments, questionable exclusion restrictions, failure to control for obvious factors, and incorrect calculation of standard errors which in turn has led to faulty statistical inference. The lack of variation in the key underlying explanatory variables and the heavy influence exerted by a few observations in state panel data regressions is a fundamental problem for all panel data studies of this question, leading to overwhelming model uncertainty.

Conclusions

We find the recent panel literature on whether there is a deterrent effect of the death penalty to be inconclusive as a whole, and in many cases uninformative. Moreover, we do not see additional methodological tools that are likely to overcome the multiple challenges that face researchers in this domain, including the weak informativeness of the data, a lack of theory on the mechanisms involved, and the likely presence of unobserved confounders.  相似文献
