Previous scholarship has demonstrated that female lawmakers differ from their male counterparts by engaging more fully in consensus‐building activities. We argue that this behavioral difference does not serve women equally well in all institutional settings. Contentious and partisan activities of male lawmakers may help them outperform women when in a polarized majority party. However, in the minority party, while men may choose to obstruct and delay, women continue to strive to build coalitions and bring about new policies. We find strong evidence that minority party women in the U.S. House of Representatives are better able to keep their sponsored bills alive through later stages of the legislative process than are minority party men, across the 93rd–110th Congresses (1973–2008). The opposite is true for majority party women, however, who counterbalance this lack of later success by introducing more legislation. Moreover, while the legislative style of minority party women has served them well consistently across the past four decades, majority party women have become less effective as Congress has become more polarized. 相似文献

Previous studies on Diptera have shown the potential for the use of cuticular hydrocarbons' analysis in the determination of larval age and hence the postmortem interval (PMI) for an associated cadaver. In this work, hydrocarbon compounds, extracted daily until pupation from the cuticle of the blowfly Lucilia sericata (Diptera: Calliphoridae), have been analyzed using gas chromatography–mass spectrometry (GC–MS). The results show distinguishing features within the hydrocarbon profile over the period of the larvae life cycle, with significant chemical changes occurring from the younger larvae to the postfeeding larvae. Further interpretation of the chromatograms using principal component analysis revealed a strong correlation between the magnitudes of particular principal components and time. This outcome suggests that, under the conditions of this study, the cuticular hydrocarbons evolve in a systematic fashion with time, thus supporting the potential for GC–MS analysis as a tool for establishing PMI where such a species is present. 相似文献

The 43 police forces in England and Wales have made over 13 million arrests in the last decade. Yet, despite this high volume criminal justice system activity, and evidence of substantial health morbidity across the criminal justice pathway, mental health services in police custody have only been patchily developed, and the literature in this area is limited. Referrals (n = 1092) to a pilot mental health service operating across two police stations in a London borough were examined over an 18-month period in 2012/2013. The referred group had high levels of mental health and substance misuse problems (including acute mental illness, intoxication and withdrawal), self-harm, suicide risk and vulnerability (including intellectual disability), with some important gender differences. Although this work has limitations, the findings are broadly consistent with the small existing literature and they confirm the need for services that are sufficiently resourced to meet the presenting needs. 相似文献

This study compared full-body digital radiography (DR) with multidetector computed tomography (MDCT) in the postmortem evaluation of gunshot wound (GSW) victims. Thirteen consecutive male GSW victims (mean age, 27 years) had full-body DR and MDCT prior to routine autopsy. DR successfully identified all metallic fragments, but MDCT was superior in its ability to precisely determine location because it provided 3-dimensional anatomic localization. In all cases, MDCT more accurately assessed organ injuries and wound tracks. Both DR and MDCT are limited in classifying multiple wounds and major vessel injury, but MDCT is generally superior to DR. MDCT shows significant advantages over DR in the forensic evaluation of GSW victims. This is particularly advantageous for the pathologist retrieving metallic fragments and for describing fracture detail accurately. Use of MDCT instead of radiographs will require medical examiners to become familiar with reading cross-sectional images. 相似文献

Cooperative research centers (CRCs) are key mechanisms for national and subnational governments and private industry for achieving
social and economic outcomes with science and technology. Despite growing policy and scholarly interest in the management
and productivity of CRCs, their complex and variegated nature has led to limited and inconsistent understanding of CRCs. In
this introduction to this Special Issue of The
Journal of Technology Transfer, we discuss the impetuses for and embodiment of CRCs as government policies, industry strategies, and organizations and thus
address a number of unexplored aspects of CRCs that are important to decision making for both policy and management. Of note,
we discuss the lack of definitional clarity regarding CRCs and introduce criteria for distinguishing CRCs from other organizations.
We conclude by introducing the article contributions, which are international in scope and address CRCs from multiple theoretical
perspectives and levels of analysis, and by discussing areas for future research. 相似文献

Purpose. Through an examination of serial rape data, the current article presents arguments supporting the use of receiver operating characteristic (ROC) analysis over traditional methods in addressing challenges that arise when attempting to link serial crimes. Primarily, these arguments centre on the fact that traditional linking methods do not take into account how linking accuracy will vary as a function of the threshold used for determining when two crimes are similar enough to be considered linked. Methods. Considered for analysis were 27 crime scene behaviours exhibited in 126 rapes, which were committed by 42 perpetrators. Similarity scores were derived for every possible crime pair in the sample. These measures of similarity were then subjected to ROC analysis in order to (1) determine threshold‐independent measures of linking accuracy and (2) set appropriate decision thresholds for linking purposes. Results. By providing a measure of linking accuracy that is not biased by threshold placement, the analysis confirmed that it is possible to link crimes at a level that significantly exceeds chance (AUC = .75). The use of ROC analysis also allowed for the identification of decision thresholds that resulted in the desired balance between various linking outcomes (e.g. hits and false alarms). Conclusions. ROC analysis is exclusive in its ability to circumvent the limitations of threshold‐specific results yielded from traditional approaches to linkage analysis. Moreover, results of the current analysis provide a basis for challenging common assumptions underlying the linking task. 相似文献

This paper uses data on tenth graders from the 2016 Caring Communities Youth Survey (CCYS) to examine the lifetime abstainer from drugs. The abstainer has been a part of Life Course Development literature; within each of the several ages of onset models. Using a model which examines the abstainer from each drug and all drugs, the effect of Prosocial Factors (peer and school) are examined. Findings indicate a very low relationship between high protective/prosocial factors and abstaining. The research of Moffitt that there may be several subtypes of abstainers is supported. 相似文献

This article considers both the Fixed‐term Parliaments Act 2011 (FTPA) and the political constitution, to place the former in its political and constitutional context. It begins by setting out the background to the FTPA – which was a part of a Coalition agreement – and considers difficulties with the most commonly‐made arguments in favour of fixed‐term parliaments. The second part of the article considers the impact and potential practical legal consequences if the FTPA is repealed without any replacement, arguing that it will only be possible to revive the ‘dissolution’ prerogative by express words in a new Act. The final part of the article addresses the question of whether the prerogative should be revived, before arguing both that it should not and that a statutory power to call an election should be conferred on the Prime Minister subject to a vote by simple majority in the House of Commons. 相似文献

Probation officers are the focal point for most interventions with delinquent youths in the juvenile justice system. The present
study examines probation strategies and interventions in a sample of 308 probation officers who completed the Probation Practices
Assessment Survey (PPAS) in a web-based survey. The PPAS measures six probation approaches: deterrence, restorative justice,
treatment, confrontation, counseling, and behavioral tactics. Structural equation models and latent class analyses showed
that probation officers use multiple approaches with delinquent youths consistent with the balanced and restorative justice
movement. Younger youths, high-risk youths, and youths with prior social service involvements are likely to receive more intensive
interventions. The implications of these findings for improving probation practices with delinquent youth are discussed. 相似文献
