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

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

Women who fought the Americans and the South Vietnamese in the Vietnam War performed many tasks. Some were the usual women's work: nursing, providing food, shelter, repairing trails, and preparing ambushes. But, they also were useful as combatants and spies. Less obvious than men, they exchanged information on troop movements while at market. They were couriers, demonstrators and recruiters. They fought and also performed intelligence through ingenious strategems. One old woman cut off her hair, was half naked, and convinced the Southern troops that she was harmless; then she entered a base and gathered information that aided the NLF forces to defeat the enemy. The communist women were indeed a key to victory. 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

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

A collaborative exercise was carried out by the Spanish and Portuguese ISFG Working Group (GEP-ISFG) in order to evaluate the performance of two Y-chromosome STR PCR tetraplexes, which include the loci DYS461, GATA C4, DYS437 and DYS438 (GEPY I), and DYS460, GATA A10, GATA H4 and DYS439 (GEPY II). The participating laboratories were asked to type three samples for the eight markers, using a specific amplification protocol. In addition, two control samples, with known haplotypes, were provided. The results obtained by the 13 different participating laboratories were identical, except for two laboratories that failed to type correctly the same two samples for GATA C4. By sequence analyses, two different GATA C4 allele structures were found. One control sample (allele 21) and two questioned samples (allele 22, correctly typed by all the laboratories, and allele 25) presented the following repeat structure: (TCTA)4(TGTA)2(TCTA)2(TGTA)2(TCTA)n, but different from the one found for allele 26 in one sample included in this exercise, as well as in the second control sample (allele 23), namely (TCTA)4(TGTA)2(TCTA)2(TGTA)2(TCTA)2(TGTA)2(TCTA)n. The collaborative exercise results proved that both Y-tetraplexes produce good amplification results, with the advantage of being efficiently typed using different separation and detection methodologies. However, since GATA C4 repeat presents a complex structure, with alleles differing in sequence structure, efficient denaturing conditions should be followed in order to avoid typing errors due to sizing problems. 相似文献
