A persisting question in international studies is whether academic research can have an impact on the making of foreign policy. Much research has shown that policy decisions can be greatly influenced by misperceptions, just as much as by objective factors. The article describes an effort by academic researchers to challenge U.S. policymakers' image of an actor in the U.S. foreign policy process—the American public. The study's focus was a widely held assumption in the U.S. foreign policy community that the American public in the wake of the Cold War was entering a renewed phase of isolationism, similar to the interwar years. The study first interviewed policy practitioners on their perceptions of the public, then performed a comprehensive review of existing polling data, and finally conducted new polls with input from policymakers themselves. The net result of the elite interviews and the analysis of public attitudes revealed a significant gap in all areas, which is presented in synopsis. Interviews with policy practitioners reveal two key dynamics that could well contribute to policymakers' misreading the public: a failure to seek out information about the public and a tendency to assume that the vocal public is representative of the general public. Indications that the study did have some impact on the thinking of policy practitioners are discussed in the conclusion.  相似文献

This is the first installment in what we hope will be a recurring series of Forums in ISP. In each segment we intend to provide an outlet for peer-reviewed dialogue and debate on important topics in the field and to allow our readers to discuss material previously printed in the pages of ISP. Below are two comments on "Challenging U.S. Policymakers' Image of an Isolationist Public" by Steven Kull and Clay Ramsay published in ISP 1:1. Both comments raise a number of important issues pertaining to the relationship of public opinion and foreign policy, and also address more general questions of domestic impact on foreign policy outputs and several significant methodological questions about approaches to polling. The Forum begins first with comments by Richard Clark and Kenneth Dautrich, is followed by comments from Shoon Murray, and concludes with a response from Kull and Ramsay.  相似文献

日本侵犯商业秘密犯罪中的商业秘密包括秘密管理性、非公知性与有价值性三个要素,较中国商业秘密构成要素的界定更为合理。中日将违约而使用、公开权利人商业秘密的行为犯罪化有违刑法的谦抑性,应予取消。中国侵犯商业秘密犯罪不宜效仿日本只定性不定量的立法模式,对于司法实践中出现的重大损失等情节的适用困境,可以通过增设定罪量刑情节的方式予以完善。中日侵犯商业秘密犯罪刑罚设置中应采取限额罚金与倍比罚金相结合的罚金制;针对不同的危害行为与主体增设多个量刑档次,做到罪刑结构的协调。  相似文献

"王朝案"的发生引发了三个证据法上的疑难问题:一是证据的合法性问题,主要涉及侦查人员无管辖权取证的效力问题;二是瑕疵证据的补正和合理解释"度"问题;三是证据采信的公正性问题,尤其是特殊侦查措施所获证据应否公开质证的问题。从证据法理上讲,侦查机关虽然违反管辖权而取证,但若并未侵犯被追诉人公正审判权,所获证据自无排除之必要;瑕疵证据的补正或合理解释"度",以确证瑕疵证据的客观性和真实性为已足;特殊侦查措施所获的证据材料,虽然可以不向公众公开,即实行不公开审理,但却必须向辩方公开特殊侦查的结果,并允许辩护人参与该证据的质证过程。  相似文献

Body mass has been neglected as a possible predictor of suicidal behavior. The present investigation explores the association between body mass index and completed suicide. Data are from the National Mortality Followback Survey and refer to 373 suicides, and 518 deaths from motor vehicle accidents as controls. The results of a logistic regression analysis indicated that, for females, the greater the BMI the greater the suicide risk. However, this relationship did not hold up under controls for race and other covariates of BMI. For males, the BMI was not significantly related to suicide risk either at the bivariate or multivariate levels of analysis. The best predictors of suicide were living alone for females, and alcohol abuse for males.  相似文献

It may be difficult to distinguish the cause of death in drowning cases without specific findings. The aim of this study was to explore the forensic value of thoracic postmortem computed tomography (PMCT) using routine images and three-dimensional (3D) image reconstructions. The imaging data of PMCT examinations of six drowning cadavers, aged 21–54 years, were analyzed. Twelve victims of sudden death from coronary artery disease (CAD) were chosen as a control group. After 3D bilateral lung images were reconstructed using image processing software, an interactive medical image control system was used to measure and analyze parameters including lung volume, lung volume ratio, mean CT value of the whole lung, and lung CT value distribution curves. Lung volume and lung volume ratio were used to assess the shape changes of the lung. Lung CT value distribution curves showed the corresponding number of pixels of the different CT values in the lung image. Lung volume was not significantly larger in drowning cases (mean 2 958 cm3) than in controls (mean 2 342 cm3). Lung volume ratio values in the drowning group (mean 0.3156) were greater than those in the control group (mean 0.2763); (P = 0.02). There was no significant difference between the drowning and control group in the mean CT value of the whole lung. There were differences between lung CT value distribution curves in drowning victims and controls, with drowning victims showing a single peak and CAD cases showing a bimodal distribution. Thoracic PMCT is helpful for the forensic medical diagnosis of drowning. Lung volume ratio and lung CT value distribution are potential indicators to distinguish between drowning and CAD.  相似文献

ABSTRACT

Studies have demonstrated the efficacy of the Scharff technique for gathering human intelligence, but little is known about how this efficacy might vary among different samples of practitioners. In this training study we examined a sample of military officers (n?=?37). Half was trained in the Scharff technique and compared against officers receiving no Scharff training. All officers received the same case file describing two sources holding information about a terrorist attack. University students (n?=?74) took the role of the semi-cooperative sources. Scharff-trained officers adhered to the training as they (1) aimed to establish the ‘knowing-it-all’ illusion, (2) posed claims as a means of eliciting information, and (3) asked fewer explicit questions. The ‘untrained’ officers asked many explicit questions, questioned the reliability of the provided information, pressured the source, and displayed disappointment with the source's contribution. Scharff-trained officers were perceived as less eager to gather information and left their sources with the impression of having provided comparatively less new information, but collected a similar amount of new information as their untrained colleagues. The present paper both replicates and advances previous work in the field, and marks the Scharff technique as a promising technique for gathering human intelligence.  相似文献

Aviation expansion and the construction of a third runway at Heathrow airport is firmly back on the political agenda. Yet, the stark fact remains that a growing list of British governments has been unable to engineer a partial or temporary policy settlement in aviation. In exploring the challenges of reaching such a settlement, this article characterises the shifting and contested political and policy contexts of UK aviation. It begins by exploring the ‘wicked issue’ of aviation expansion before foregrounding how the politics of air travel is riven by competing policy frames, fragmented governance and the absence of gatekeepers. It argues that the Davies Commission and its efforts to remove aviation from the domain of partisan politics provided little more than a temporary respite for government. It thus concludes by questioning whether the May government's expansion proposals will succeed this time around, outlining how the contributions in this collection address the themes and issues of this overriding policy puzzle.  相似文献
