Within the context of transboundary disputes, this paper seeks to determine which liability concept, negligence or strict liability, performs better when assets are secure against foreign claims for transboundary damages. Our results indicate that, if assets are hidden from foreign claims, strict liability will not implement the socially optimal outcome, but neither will negligence. However, even though the socially optimal outcome is not always achieved, strict liability weakly dominates negligence. These results suggest that the harmonization of statues that deal with transboundary pollution should be based on strict liability not negligence.

This article critically appraises the narrative of nationalist resurgence in China in the 1990s that structures much of the secondary literature on Chinese politics since Tiananmen. Adopting a post-structuralist method, Chinese texts from the 1990s are treated as discursive rather than as expressions of a common consensus, emergent ideology or political movement. This makes it possible to bring out the disparate points of view concerning the desirability of nationalism for China and to understand the strategies that are being deployed by authors within the context of everyday Chinese politics. It also reveals the significance of the absence from both the primary and the secondary texts of any mention of the advocacy of nationalism by the political leadership. When this hidden discourse is taken into account, it becomes evident that many of the texts that have been taken as expressions of a nationalist revival are either not particularly interested in nationalism or are highly sceptical concerning its possibilities for solving the problems faced by the Chinese state. Particularly significant is the way in which many of the texts locate themselves in relation to the official discourse on nationalism by appropriating its themes in order to promote and legitimate a wide range of other discourses with which it can be bound up, ranging from democracy to authoritarianism.  相似文献

A mock jury study was conducted to test the hypothesis that perceptions of a witness can be biased by presumptuous cross-examination questions. A total of 105 subjects read a rape trial in which the cross-examiner asked a question that implied something negative about the reputation of either the victim or an expert. Within each condition, the question was met with either a denial, an admission, or an objection from the witness's attorney. Results indicated that although ratings of the victim's credibility were not affected by the presumptuous question, the expert's credibility was significantly diminished—even when the question had elicited a denial or a sustained objection. Conceptual and practical implications of these findings are discussed.This research was supported by funds provided to the first author by the Bronfman Science Center.  相似文献

Jail and prison populations in the United States have continued to grow unabated during the past two decades but crime rates have not declined. Partly in response to the pressures caused by burgeoning correctional populations, the use of alternatives to incarceration has expanded. An ongoing debate centers on the effectiveness of these alternatives. Many criminal justice professionals and some researchers question whether such alternatives seriously restrict the criminal justice system 's ability to incapacitate the active offender. This study deals specifically with two alternatives to incarceration: probation and parole. We examine offender recidivism for a sample of probationers and parolees active in New Orleans, Louisiana, and offer a new approach to addressing the effectiveness issue. Past research has evaluated the effectiveness of alternatives by examining failure rates of diverted offenders. High failure rates, we argue, do not necessarily imply a significant loss of the incapacitative effects of imprisonment. We suggest that a more appropriate measure of the loss of incapacitative effect is the proportion of all offenses committed by persons on probation or parole. Our results suggest that such losses are surprisingly low. The policy implications of our findings are discussed.  相似文献

A review of the available literature does not reveal a plausible explanation as to why the incisal edges of maxillary anterior teeth do not always mark clearly. Generally, the mandibular incisal edges do mark with some consistency. This paper demonstrates through test bites on skin that the answer lies in the position of the mandible.  相似文献

Postmortem examination of a former professional basketball player revealed an abnormal heart, most notably a single coronary artery. The literature on single coronary arteries is briefly reviewed, and the possible mechanism which caused the patient's condition is considered. This case is particularly unusual because of the patient's profession, which is so physically demanding.  相似文献
