3,4-Methylenedioxymethamphetamine (MDMA) tablets known as "ecstasy" became a very popular drug amongst Israeli youth in the last decade. The ecstasy tablets have a simple design impressed on them (logos) making it relatively easy to distinguish between various logos. The life expectancy of ecstasy tablet logos, defined as the period between the first seizure by the police of a certain logo until the last seizure of the same logo, was monitored during the years 2001-2003. During this time interval, 58 different tablet logos were seized. A total of 26 logos, defined as common logos with at least 10 independent seizures, were observed. At any given time interval during this period, 8-10 common logos were found with an average life expectancy of approximately 9 months. Five of the observed 26 common logos were defined as the most common logos that appeared in at least 200 independent seizures each. Plots of the number of seizures and number of tablets seized as a function of time are presented and discussed as well as explanations for the high turnover rate of any given logo. 相似文献

We investigated ventilatory and metabolic demands in healthy adults when placed in the prone maximal restraint position (PMRP), i.e., hogtie restraint. Maximal voluntary ventilation (MVV) was measured in seated subjects (n=30), in the PMRP, and when prone with up to 90.1 or 102.3 kg of weight on the back. MVV with the heaviest weight was 70% of the seated MVV (122+/-28 and 156+/-38 L/min, respectively; p<0.001). Also, subjects (n=27) were placed in the PMRP and struggled vigorously for 60 sec. During the restrained struggle, ventilatory function (V(E)/ MVV) was 44% of MVV in the resting PMRP. While prone with up to 90.1 or 102.3 kg on the back, the decrease in MVV was of no clinical importance in these subjects. Also, while maximally struggling in the PMRP, V(E) was still adequate to supply the ventilatory needs. 相似文献

AbstractRecent trends in “China scholarship” include two dominant sets of goals and foci in examining China's socialist revolution. Exponents of the more traditional view, represented here by Lucian Pye's Mao Tse-tung, seek to explain it away as a pathological deviation from “normality” in social development. The extremism of Pye's book makes it almost a caricature of the worst in the first trend. By the same token this extremism makes the prejudices and assumptions on which this trend is based easier to perceive than would be the case with other more subtle works. The less traditional and less frequently published view, represented here by Nee and Peck's China's Uninterrupted Revolution attempts to comprehend the Chinese Revolution, historically and philosophically, as a meaningful process directed at increasing human liberation. 相似文献

The failure of ‘third’ parties to displace their larger rivals is a consistent (although not universal) feature of competitive democracies which have simple majority electoral systems. It is argued that there are structural features intrinsic to most third parties which tend to accelerate the process of decline once it has set in. Because of their reliance on individual members, these parties put great stress on individual participation and provide the opportunities for it. As a result, they are particularly subject to the effects of internal competition which electoral decline is likely to intensify. The study tests this hypothesis by looking at two cases of third party decline, and concludes that the mass branch party format is ill‐able to cope with electoral failure. 相似文献

The purpose of US foreign assistance has shifted in the wake of 2001, and Washington has resurrected practices previously associated with police aid during the Cold War. In particular, the Bush administration has broadened the remit of the United States Agency for International Development (usaid) in such a way as to make it a quasi-security agency. The consequences of this could be significant for both usaid and democratic-style police assistance programmes more generally, for today's threat-driven policies are part of a trend which in the past has had worrying consequences. Using the critical variable of public policing (which is illustrated by reference to developments in Kenya), I argue that using usaid to improve the counter-terrorist capacity of Africa's police in the pursuit of US national security objectives is a seriously flawed strategy. 相似文献

The theory of “preventive war” states that, under certain conditions, states respond to rising adversaries with military force in an attempt to forestall an adverse shift in the balance of power. British and French passivity in response to the rapid rise of Germany in the 1930s would appear to constitute one of the leading empirical anomalies in the theory, one the theory's proponents must explain. After clarifying the meaning of the preventive motivation for war and specifying the conditions under which it should be the strongest, we examine French and British behavior in the crises over the Rhineland in 1936 and Sudeten Czechoslovakia in 1938 through an intensive study of government documents and private papers. We argue that French political leaders, anticipating a continuing adverse shift in relative power, wanted to confront Hitler, but only with British support, which was not forthcoming. British leaders believed, even by 1936, that the balance of power had already shifted in Germany's favor, but that German ascendancy was only temporary and that British rearmament would redress the balance of power in a few years. We contrast our argument with alternative interpretations based on domestic political pressures and ideologically driven beliefs and interests. 相似文献

Interventions aimed at increasing the supply and representativeness of elected officials range from facilitative to the formally authorised. This paper reports on a field experiment aimed at testing the effect of facilitative approaches at the local level based on a collaboration between parish councils and the research team. We randomly allocated 818 parish council clerks across five counties in Southern England, either to receive information and the opportunity for member training for recruitment, or not to receive this contact. We investigated the effect of this intervention on political recruitment. Despite evidence of an effect on use of social media, our results suggest that there are significant institutional and structural barriers to participation in local politics that cannot easily be overcome using facilitative measures. 相似文献
