The most ferocious debates are about whether the United States should be described as imperial, but in practice other countries also try to influence other countries’ domestic policies, to propagate their visions, to exert power and to stabilize areas beyond their borders that are perceived as a source of threats. While in the 1990s the winners of globalization were seen as small open states, since the turn of the millennium big powers appear to be gaining because of their ability to project political power: the United States, but also China, Russia, India, and Brazil. This makes for a greater instability and leads to the formulation of theories of realism or neo-realism. The essay concludes with an examination of alternatives to empire and the neo-imperial vision, in particular the importance of elaboration of common or shared values in helping to build a safer and more peaceful international order.  相似文献

A fatality following ingestion of the drug baclofen (Lioresal) is described. Baclofen was identified in urine by gas chromatography/mass spectrometry. After derivatization with trinitrobenzene sulfonic acid, baclofen was quantitated in serum and urine by high-performance liquid chromatography. The concentration of baclofen was 17 mg/L in serum and 760 mg/L in urine collected approximately 12 h after the overdose. To our knowledge, this is only the second reported fatality involving a baclofen overdose. The previous case did not include quantitation of baclofen in any biological fluid.  相似文献

We use data from 1983 and 1985 on the volume of Medicare physician services to analyze whether Medicare's Prospective Payment System (PPS), which resulted in a significant decline in hospital spending, led to a partially offsetting increase in real expenditures for physician services. We also analyze the effect of increases in assignment rates, increasing incomes of the elderly, and other factors on real expenditures during this period. Our main conclusion is that PPS has at most a small positive effect on real physician expenditures. Because people spent less time in the hospital, Medicare physician spending declined; but because of incentives to shift radiology and other services out of the hospital, some of this decline was offset. We also conclude that the sharp increase in Medicare assignment rates over this period, along with the rising incomes of the elderly during this period, contributed to the observed growth.  相似文献

In the public debate over incarceration policy, there is considerable disagreement about what value of individual offending frequency (λ) is appropriate to use in estimating incapacitative effects. This article provides an approach for estimating the mean values of λ for diverse subsets of the total offender population, with particular emphasis on subsets generated by filtering through various stages of the criminal justice system. Sharp differences in offending frequency are displayed between robbery and burglary inmates, across three states, and particularly between resident inmates and free, active offenders. Free offenders average 1 to 3 robberies and 2 to 4 burglaries per year, while resident inmates have λ values 10 to 50 times higher. Differences result from the underlying levels of criminal activity and the sanction Levels that offenders face. A highly heterogeneous distribution of offending frequency in the total population of offenders combines with relatively Low imprisonment levels to lead to substantial selectivity of high-λ offenders among resident inmates and a correspondingly low mean value of λ among those offenders who remain free. These results have important implications for estimating incapacitative effects of an increase in incarceration, since the additional inmates will be drawn from free offenders whose mean λ is at least an order of magnitude Lower than that of the current inmate population.  相似文献

We investigated the differences in the levels of carboxyhemoglobin (COHb), cyanide (HCN) and petroleum fuels (gasoline and kerosene) between left and right ventricular bloods from fire victims. COHb was slightly, and HCN and petroleum fuels were markedly higher levels in the left than those in the right. These effects were so called 'first pass phenomena' due to the circulation, diffusion and metabolization before the deaths of fire victims.  相似文献

To account for variance in great powers responses to threats and the implications for the peacefulness of the international system since the late nineteenth century, this article elucidates a theory which refines and synthesizes economic liberal perspectives and realist balance of power theory. I argue that different patterns and levels of economic interdependence in the great power system generate societal-based economic constraints on, or incentives for, state leaders of status quo powers hoping to mobilize economic resources and political support to oppose perceived threats. This mobilization process influences strongly the preferences of status quo powers, other states beliefs about those preferences, and the interpretation of signals in balance of power politics. In this way, economic ties influence the strategies great powers pursue. Firm balancing policies conducive to peace in the international system are most likely, I then hypothesize, when there are extensive economic ties among status quo powers and few or no such links between them and perceived threatening powers. When economic interdependence is not significant between status quo powers or if status quo powers have strong economic links with threatening powers, weaker balancing postures and conciliatory policies by status quo powers, and aggression by aspiring revisionist powers, are more likely. I then illustrate how these hypotheses explain the development of the Franco-Russian alliance of the 1890s and its effectiveness as a deterrent of Germany up to 1905, British ambivalence toward Germany from 1906 to the First World War, the weakness of British, French, Soviet, and American behavior toward Germany in the 1930s and World War II, and the American and European responses to the Soviet threat, including the NATO alliance, and the "long peace" of the post-1945 era.  相似文献
