The ability of the minority party to influence legislation in Congress is debated. Most bills are passed with large bipartisan majorities, yet the House, where most legislation is developed, is seen as a majority-party-dominated institution. I develop a theory of House minority-party influence at the committee markup stage as a result of the Senate’s institutional rules. An original data set of congressional committee votes shows that minority-party support in House committees predicts House and Senate passage. During unified party control of the chambers, an increase in Senate majority-party seats results in lower minority-party support for the legislation in the House committee, while during divided party control of Congress, the House majority passes more extreme bills as the chambers polarize. Even in the majority-party-dominated House, the minority’s preferences are incorporated into legislation, and the Senate’s institutional rules moderate bills to a significant degree. 相似文献

Involvement in custody cases that include accusations of parental alienation—whether as an evaluator, expert witness, lawyer, judge, therapist, provider of a specialized intervention, or researcher—incurs both professional and personal risks. Some risks relate to false negative or false positive identifications of parental alienation that can lead to regulatory agency complaints and public condemnation by the parent who feels wronged by the case outcome. Other risks stem from providing services in an emerging area of practice and working with children who overtly oppose repairing the relationship with their rejected parent. These risks include: unfounded accusations of mistreating children; negatively biased commentary and sensationalist attacks in the media and in social media, professional conferences and journals, and in courtroom testimony; harassment, vilification, and invasion of privacy; threats of violence and public humiliation; shunning and rumor spreading by colleagues; and complaints to regulatory agencies. This article examines circumstances, beliefs, and dynamics that give rise to these risks, suggests precautions to reduce the risk of false accusations against professionals, and offers recommendations for dealing with regulatory agencies. Criticisms that a court or service provider has mistreated a child merit careful scrutiny in the context of the case evidence and empirical data. While some interventions for alienated children raise legitimate concerns, others have been maligned by anecdotal complaints that studies show do not represent the experience of most participants. 相似文献

Bayes factors provide a continuous measure of evidence for one hypothesis (e.g., the null, H0) relative to another (e.g., the alternative, H1). Warmelink et al. (2019, Legal Criminol Psychol, 24, 258) reported Bayes factors alongside p‐values to draw inferences about whether the order of expected versus unexpected questions influenced the amount of details interviewees provided during an interview. Mac Giolla & Ly (2019) provided several recommendations to improve the reporting of Bayesian analyses and used Warmelink et al. (2019) as a concrete example. These included (I) not to over‐rely on cut‐offs when interpreting Bayes factors; (II) to rely less on Bayes factors, and switch to ‘nominal support’; and (III) to report the posterior distribution. This paper elaborates on their recommendations and provides two further suggestions for improvement. First, we recommend deception researchers report Robustness Regions to demonstrate the sensitivity of their conclusions to the model of H1 used. Second, we demonstrate a method that deception researchers can use to estimate, a priori, the sample size likely to be required to provide conclusive evidence. 相似文献

Parenting Coordination is a “hybrid legal‐mental health role that combines assessment, education, case management, conflict management, dispute resolution and, often times, decision‐making functions (AFCC, 2019, https://www.afccnet.org/Portals/0/PublicDocuments/Guidelines%20for%20PC%20with%20Appendex.pdf?ver=2020-01-30-190220-990 ). This article addresses issues that arise when the case has allegations or findings of intimate partner violence (IPV). Considerations of the type of IPV, the severity, timing, perpetrator and effects on coparenting are discussed in the context of the parenting coordinator's role. Through screening and assessment, we differentiate the kinds of cases with the presence of IPV where a PC may be effective as opposed to other IPV cases that may not predict success for retaining a PC. 相似文献

Correctly assessing heart weight can be critical at postmortem examination. The current international guidelines advocate using the short-axis method in dissecting the heart and the heart weighed when the blood is emptied. However, it did not specify at what point the heart should be weighed or how the blood should be emptied. This study compared heart weights at three different time points during the heart examination (immediately after dissecting out of the pericardial sac with blood still in chambers, blood washed/removed from heart chambers without the heart opened, and the heart completely opened, blood emptied, and pad dried). This was to illustrate the variation in measurement and potential errors when the heart is weighed at different time of dissection. The results show that there were statistical and clinical significant differences between the heart weights at each weighing points. We recommend the heart to be completely dissected with any blood and residual washing/rinsing water emptied before being weighed. Although performed in this study, the effect of pad drying the heart on heart weight was not explored and was a limitation in this study. 相似文献

Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs. 相似文献
