Undergraduate public law courses often attract students with competing expectations. Some students enroll in these courses to prepare for law school, while others enroll in the courses to gain a broader understanding of courts in the American system of government. These differing student constituencies can create a dilemma for instructors. A course designed to cater to students with a general interest in the judiciary may not afford prelaw students with an appreciation for the demands of the legal profession. Conversely, a course narrowly tailored toward prelaw students risks alienating the majority of students for whom this class may be their only look at the judiciary. As a means to promote pedagogical balance and to appeal to varied student constituencies, we profile five public law simulations in this article that engage students in active learning and promote a greater understanding of law and courts.  相似文献

Why the uprisings that broke out across the Middle East and North Africa in 2010-11 ousted the leaders of republics but left monarchies largely intact remains puzzling. One promising explanation for the resilience of monarchical regimes argues that monarchs exercise repression in a comparatively restrained and largely effective fashion. Proponents of this theory tend to conflate two crucial causal factors: the level of state coercion exercised against opposition activists and the degree of indiscriminateness with which coercion is deployed. By treating these variables as analytically distinct, a more compelling explanation for monarchical resilience can be advanced. The advantages of the revised argument are illustrated by revisiting the divergent trajectories of the uprisings in Bahrain, Oman, Saudi Arabia and Kuwait.  相似文献

This article focuses on the discursive construction in Britain of a middle-class moral panic occasioned by the distress caused to self-styled 'responsible mortgage borrowers' by falling house prices. In the context of the move towards asset-based welfare the sub-prime crisis manifested itself most obviously in the popular consciousness as a threat to housing market wealth. The Labour government used the political space opened up by the narrative of middle-class moral panic in order to protect banks' balance sheets from the consequences of their own failed investments in mortgage-backed securities. The ensuing arrangements immunised banks from the implications of market self-regulation in the first-phase response to the sub-prime crisis while simultaneously allowing them to continue to impose the experience of market self-regulation on their customers. An increasingly asymmetric approach to banking regulation has arisen analogous to that which Karl Polanyi associated with the contradictory co-existence of market and non-market forms.  相似文献

Trade has again emerged as a controversial issue in America, yet we know little about the ideas that guide American thinking on these questions. By combining traditional survey methods with experimental manipulation of problem content, this study explores the ideational landscape among elite Americans and pays particular attention to how elite Americans combine their ideas about commerce with their ideas about national security and social justice. We find that most American leaders think like intuitive neoclassical economists and that only a minority think along intuitive neorealist or Rawlsian lines. Among the mass public, in contrast, a majority make judgments like intuitive neorealists and intuitive Rawlsians. Although elite respondents see international institutions as promising vehicles in principle, in practice they favor exploiting America's advantage in bilateral bargaining power over granting authority to the World Trade Organization. The distribution of these ideas in America is not arrayed neatly along traditional ideological divisions. To understand the ideational landscape, it is necessary to identify how distinctive mentaal models—mercantilist, neorealist, egalitarian, and neoclassical economic—sensitize or desensitize people to particular aspects of geopolitical problems, an approach we call cognitive interactionism.  相似文献

自从1979年中国实行改革开放以来,菲中两国的经济关系持续发展。菲律宾对华贸易要比它与世界其他国家的贸易增长得更快。近几年来,我们可以看到,由于菲律宾比素对人民币的比值相对较低,菲律宾对华出口骤增。尽管中国在菲律宾外贸总额中所占的份额已经由80年代的2%增长到现在的4%,但总的来说仍然偏少。 当前的菲中贸易结构以工业制成品为主体。正如其整体贸易结构一样,菲律宾的对华出口贸易以半成品为主。中国的工业制品则包含更多的制成品——电子产品、金属制品和建筑材料。近几年,在中国对菲律宾出口中消费品、食品及食…  相似文献

The eyes of fourteen fatally abused children and sixteen control cases were examined histopathologically. Ten of the abused children showed intraocular change. The most common ocular changes were subdural hemorrhage of the optic nerve and retinal hemorrhage which involved all the layers of the retina, but most commonly the nerve fiber layer, ganglion cell layer and inner nuclear layer. The presence of blood cavities within the retina partially supported the hypothesis of traumatic retinoschisis. The control cases of non-abused children rarely showed intraocular hemorrhage.  相似文献

Headspace gas chromatography was used to determine the concentration of ethanol and methanol in blood samples from 519 individuals suspected of drinking and driving in Sweden where the legal alcohol limit is 0.50 mg/g in whole blood (11 mmol/l). The concentration of ethanol in blood ranged from 0.01 to 3.52 mg/g with a mean of 1.83 +/- 0.82 mg/g (+/- S.D.). The frequency distribution was symmetrical about the mean but deviated from normality. A plot of the same data on normal probability paper indicated that it might be composed of two subpopulations (bimodal). The concentration of methanol in the same blood specimens ranged from 1 to 23 mg/l with a mean of 7.3 +/- 3.6 mg/l (+/- S.D.) and this distribution was markedly skew (+). The concentration of ethanol (x) and methanol (y) were positively correlated (r = 0.47, P less than 0.001) and implies that 22% (r2) of the variance in blood-methanol can be attributed to its linear regression on blood-ethanol. The regression equation was y = 3.6 + 2.1 x and the standard error estimate was 0.32 mg/l. This large scatter precludes making reliable estimates of blood-methanol concentration from measurements of blood-ethanol concentration and the regression equation. But higher blood-methanol concentrations are definitely associated with higher blood-ethanol in this sample of Swedish drinking drivers. Frequent exposure to methanol and its toxic products of metabolism, formaldehyde and formic acid, might constitute an additional health risk associated with heavy drinking in predisposed individuals. The determination of methanol in blood of drinking drivers in addition to ethanol could indicate long-standing ethanol intoxication and therefore potential problem drinkers or alcoholics.  相似文献

A report is given of two young people who died after intake of dextromethorphan, one by suicide and the other for uncertain reasons. To our knowledge this is the first reported fatal intoxications with this drug.  相似文献
