InMaryland v. Craig, the United States Supreme Court relied heavily on a brief prepared by a committee of the American Psychology-Law Society on behalf of the American Psychological Association (APA). The APA brief concluded that sexually abused children may be particularly vulnerable to distress in the legal process, especially when forced to confront the defendant face to face, and that such acute distress may be inconsistent with the state's interests in promotion of reliable testimony and child welfare. APA also argued that psychological theory and research provide foundations for individualized determination of the need for measures to protect children from face-to-face confrontation. *** DIRECT SUPPORT *** AFE06051 00002  相似文献

The article seeks to analyse the relationship between different forms of economic calculation in the Soviet Union, concentrating on monetary calculations used by the State Bank and on the use of ‘material balances’ and of input‐output analysis in planning the Soviet economy. It provides a critique of Bettelheim's analysis of the role of monetary calculation in the Soviet Union and, using the work of Lavigne, attempts to provide a foundation for a specific analysis of economic calculation (and hence, relations of production) in the Soviet Union. The article concludes by arguing that the variety of methods of calculating used in the Soviet Union, and the generation of ‘needs’ by organisational exigencies which may not be fully taken into account in the main methods of calculation, undermine the common conception of planning as the rational pursuit of certain ideal ends, a conception which is unfortunately still influential in many socialist conceptions of planning. Finally, in rejecting the view that one can conceive of socialism as a certain ideal state of affairs, the article argues that political critiques of the Soviet Union do not entail the rejection of the view that it is a socialist society.  相似文献

In the 2003 recall election in California, Lt. Gov. Cruz Bustamante received more than 1.25 million fewer votes in the replacement election than votes cast against the recall of Gray Davis. A much smaller group voted "yes" on the recall but voted for Bustamante. The principal underlying explanation is racial and ethnic polarization. Using L.A. Times exit poll data, we compare the characteristics of voters who displayed the two unusual behavioral patterns with those who voted in more conventional ways. We find that Latinos and African Americans are far less likely than non-Hispanic whites and Asian Americans to have defected from Bustamante given a "no" vote on the recall, and far more likely to have voted for Bustamante given a potentially strategic "yes" vote on the recall. The patterns of defection are consistent with racial polarization on Proposition 54, lending further credence to our claim that race and ethnicity persists as an important factor in vote choice, even in environments with a history of minority electoral success.  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

An accruing body of evidence supports associations between self-perceived gender typicality and peer relationship difficulties; however, researchers have yet to evaluate peers' perceptions of problem behaviors to gain insight into the social correlates of gender typicality. A short-term longitudinal study was conducted to evaluate associations between gender atypical problem behavior and subsequent peer relational difficulties for 2,076 fifth graders (M age= 10.27; 53% female). Peer nomination methodology was used to assess participants' classroom peer relationships, problem behaviors, and social-emotional characteristics. Findings showed that youth characterized by gender atypical, compared to gender typical, problem behavior (withdrawn boys/aggressive girls vs. withdrawn girls/aggressive boys, respectively) evidenced higher levels of subsequent peer difficulties; moreover, participation in a mutual friendship was associated with decreased risk for peer relationship maladjustment, particularly among youth characterized by gender atypical problem behavior. Results further revealed that, compared to friendless youth, friended youth earned higher prosocial and peer liking scores and, for withdrawn youth, lower emotional sensitivity scores. The present research contributes to our understanding of the potential short-term consequences of youth's gender atypical problem behavior. Findings underscore the need for supplemental conceptualizations of gender typicality as well as multifaceted interventions designed to promote the acceptance of gender nonnormativity, support the development of adaptive peer relationships, and reduce the occurrence of problem behaviors.  相似文献

Why do some leaders make deeper commitments to human rights treaties (HRAs) by consenting to receive extra monitoring of complaints or communications from individual citizens? Extant theory suggests leaders join HRAs for tangible benefits. However, empirical support for this argument is mixed. To address this mismatch, we approach this question from a different angle. We argue that by ratifying HRAs, leaders send a signal that they are reliable partners who value future returns. Accepting optional articles and protocols that increase monitoring of the state’s human rights behavior, without changing the state’s substantive obligations, helps better signal that the regime does not fear instability nor sees the need to resort to the proscribed abuses in the future. This, in turn, serves as an important middle step to recognizing tangible benefits, such as foreign direct investment, by improving investors’ risk perception of ratified countries.  相似文献
