Because of popular and political pressure, governments have been compelled to regulate ‘excessive’ executive compensation and search both a policy and political solution. In this paper, I seek to establish the mechanisms of policy learning, competition, and emulation by examining American and British regulatory policies of executive compensation that show evidence of reciprocal diffusion, i.e. from the US to the UK and vice versa. The evidence suggests that during the past two decades, the extent of reciprocal policy diffusion varied and was primarily driven by policy learning. Using published government reports, press releases, public hearings, newspaper articles, and interviews, I demonstrate that reciprocal learning occurred because one country's policymakers and practitioners explicitly discussed and/or referred to the practices in the other country when deciding to adopt a specific policy solution to the problem of excessive executive pay. I discuss the implications for the literature on diffusion and point out avenues for future research. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Sex determination in forensic practice is performed mostly on sexually dimorphic bones, including pelvic bones such as the os sacrum. Postmortem CT scan provides an easy and fast method for depicting and measuring bone structures prior to elaborate autopsy preparations. To develop a simple and objective method for sex determination in postmortem CT, metric data were evaluated from CT images of the pelvic-associated os sacrum of 95 corpses (49 men and 46 women) from the Canton of Bern, Switzerland. Discriminant function analysis of the data showed that the best accuracy in determining sex was 76.8% and 78.9% with two different observers. It is concluded that measuring the os sacrumin postmortem CT for sex determination has moderate accuracy and should only be applied in combination with other methods. 相似文献

This study examines the psychometric properties of the Childhood Trauma Questionnaire short form (CTQ-SF) with street youth who have run away or been expelled from their homes (N = 397). Internal reliability coefficients for the five clinical scales ranged from .65 to .95. Confirmatory Factor Analysis (CFA) was used to test the five-factor structure of the scales yielding acceptable fit for the total sample. Additional multigroup analyses were performed to consider items by gender. Results provided only evidence of weak factorial invariance. Constrained models showed invariance in configuration, factor loadings, and factor covariances but failed for equality of intercepts. Mean trauma scores for street youth tended to fall in the moderate to severe range on all abuse/neglect clinical scales. Females reported higher levels of abuse and neglect. Prevalence of child maltreatment of individual forms was very high with 98% of street youth reporting one or more forms; 27.4% of males and 48.9% of females reported all five forms. Results of this study support the viability of the CTQ-SF for screening maltreatment in a highly vulnerable street population. Caution is recommended when comparing prevalence estimates for male and female street youth given the failure of the strong factorial multigroup model. 相似文献

Many law courses include at least some elements of group work within compulsory or optional modules. The benefits of group work include at least four of the seven “Principles for Good Practice in Undergraduate Education”.1 In addition, employers consistently ask for good team-working skills, evidence of which is often provided by reference to group projects at university. Previous research by the authors2 confirms other reports in the literature that many students find group work difficult, and particularly resent other students “freeloading” from their work.3 They also experience frustration at non-participation by other students and not being able to choose their team mates. This resentment can be exacerbated if all students receive the same mark for the finished project regardless of input. In this article, the authors reflect upon our experiences of setting and grading group work in our own courses and institutions. We will consider different assessment approaches, including peer assessment,4 lecturer assessment, student participation – enhancing student understanding of assessment criteria,5 a mixture of peer and lecturer assessment, assessment of group work as part of a portfolio,6 and non-assessed group work feeding into individual assessments. 相似文献

In this article, Torsten Stein, Professor of Constitutional, European and Public International Law and Director of the Institute of European Studies at the University of Saarland, Saarbrücken, traces the constitutional development that has enabled Germany to take part in a meaningful way in United Nations peacekeeping operations (PKO). As in Japan, Germany's post-war Constitution (Basic Law) was held to prohibit such participation. Germany's Federal Constitutional Court, however, has found an interpretation of the Constitution that - without amending the Constitution or any other pertinent legislation - allows a "German solution" which reconciles the putative post-war prohibitions with Germany's obligations as a member of the United Nations. Stein, who is also a Colonel in the German Air Force Reserve, warns that the "five conditions" contained in Japan's 1992 Peacekeeping Operations Law are unrealistic in view of present day PKO, but envisages an interpretation of the Japanese Constitution that might follow the German example. 相似文献

The goal of this study was to examine the relationship between family dysfunction and wanted, unwanted, and illegal sexual experiences that occurred during childhood and adolescence. Three hundred fifty-three subjects from a sexual abuse clinic, a family practice clinic, and a family planning clinic anonymously completed a survey on childhood sexual experiences and physical violence, family substance abuse, violence toward others, and family quality. Overall, 50% had had unwanted (USE) and wanted sexual experiences (WSE) before they turned 18. Subjects in the sexual abuse clinic had the highest percentage (90%) of unwanted or illegal sexual experiences, followed by the family planning subjects (40%) and the family practice subjects (30%). Both USE and WSE were related to family dysfunction scores, even when they were controlled for demographic influences. Family dysfunction scores were highest for those who reported USE and legal WSE and were lowest for those who reported no USE or WSE. 相似文献

The postmortem diagnosis of shaken baby syndrome, a severe form of child abuse, may be difficult, especially when no other visible signs of significant trauma are obvious. An important finding in shaken baby syndrome is subdural haemorrhage, typically originating from ruptured cerebral bridging veins. Since these are difficult to detect at autopsy, we have developed a special postmortem computed tomographic (PMCT) method to demonstrate the intracranial vein system in infants. This method is minimally invasive and can be carried out conveniently and quickly on clinical computed tomography (CT) systems. Firstly, a precontrast CT is made of the infant's head, to document the original state. Secondly, contrast fluid is injected manually via fontanel puncture into the superior sagittal sinus, followed by a repeat CT scan. This allows the depiction of even very small vessels of the deep and superficial cerebral veins, especially the bridging veins, without damaging them. Ruptures appear as extravasation of contrast medium, which helps to locate them at autopsy and examine them histologically, whenever necessary. 相似文献

Simultaneous separation of different types of amphetamine and piperazine designer drugs by capillary electrophoresis with a chiral selector 总被引:1,自引:0,他引:1

The recent emergence of a new class of piperazine-type compounds has brought about the need for laboratory screening methods for both seized drugs and toxicological samples. These piperazine compounds, which include 1-benzylpiperazine (BZP) and 1-(3-trifluoromethylphenyl)piperazine (TFMPP), exhibit comparable physiological effects and can be substituted for the classic amphetamine-type drugs. We have optimized a chiral capillary electrophoresis (CE) separation that detects a set of 6 piperazine and 4 chiral amphetamine compounds in under 23 min using a 200 mM phosphate buffer at a pH = 2.8 with 20 mM hydroxypropyl- beta-cyclodextrin (HPbeta3CD). In addition to the above compounds, a series of "clandestine" BZP diHCl samples were also analyzed using this method to assess the ruggedness of the procedure. The novel CE separation was tailored to simultaneously detect these piperzine compounds in addition to amphetamine-type drugs. Distinct migration time and UV-spectral data were obtained for all compounds of interest. 相似文献
