According to the U.S. Supreme Court's decision in Jackson v. Indiana (1972), examiners must determine if a defendant has substantial probability of regaining competency through treatment in the foreseeable future. Previous research has indicated that, given the low base rate of defendants unable to be restored to competency, examiners are relatively poor at predicting which defendants will regain competency. Determining the characteristics of not restorable incompetent defendants and restorable incompetent defendants is a necessary first step toward improving examiners' ability to predict a defendant's likelihood of regaining competency. This study examined the competency evaluation reports of 468 defendants evaluated for competency to stand trial. Incompetent defendants significantly differed from competent defendants with regard to age, employment status, ethnicity, criminal charges, and psychiatric diagnosis. Few significant differences existed between defendants predicted restorable and those predicted not restorable by mental health examiners—the differences that did exist were related mainly to nonpsychiatric variables.  相似文献

Upper respiratory infection and pulmonary inflammation are common in sudden infant death syndrome, but their role in the cause of death remains controversial. Controlled studies comparing clinical upper respiratory infection and inflammation in sudden infant death syndrome with sudden infant deaths caused by accidents and inflicted injuries (controls) are unavailable. Our aim was to compare respiratory inflammation and upper respiratory infection within 48 hours of death and postmortem culture results in these two groups. A retrospective analysis of upper respiratory infection and pathologic variables in the trachea and lung of 155 infants dying of sudden infant death syndrome and 33 control infants was undertaken. Upper respiratory infection was present in 39% of sudden infant death syndrome cases and 40% of control cases. Upper respiratory infection was more likely to have occurred in association with more severe lymphocytic interstitial pneumonitis when sudden infant death syndrome cases and control cases were combined ( P=.04). Proximal and distal tracheal lymphocytic infiltration was more severe in control cases than in sudden infant death syndrome cases ( P=.01 and.01, respectively). Lymphocytic infiltrations of the bronchi, bronchioles, and pulmonary interstitium were similar between groups. Bronchial associated lymphoid tissue was more prominent in control cases ( P=.04). Cultures were positive in 80% of sudden infant death syndrome cases, 78% of which were polymicrobial. Among control cases, 89% were positive, with 94% being polymicrobial. This study confirms that microscopic inflammatory infiltrates in sudden infant death syndrome are not lethal.  相似文献

Laser-induced detection of fluorescent labeled PCR products and multi-wavelength detection (i.e., multicolor analysis) enables rapid generation of mtDNA sequencing profiles. Traditionally, polyacrylamide slab gels have been used as the electrophoretic medium for mtDNA sequencing in forensic analyses. Replacement of slab gel electrophoresis with capillary electrophoresis (CE) can facilitate automation of the analytical process. Automation and high throughput can be further enhanced by using multicapillary electrophoretic systems. The use of the ABI Prism 3100 Genetic Analyzer (ABI 3100, Applied Biosystems, Foster City, CA) as well as the ABI Prism 310 Genetic Analyzer (ABI 310, Applied Biosystems, Foster City, CA) were evaluated for mtDNA sequencing capabilities and compared with sequencing results obtained on the platform currently in use in the FBI Laboratory (the ABI Prism 377 DNA Sequencer, ABI 377, Applied Biosystems, Foster City, CA). Various studies were performed to assess the utility of the ABI 3100, as well as the ABI 310 for mtDNA sequencing. The tests included: comparisons of results obtained among the ABI 3100, the ABI 310 and the ABI 377 instruments; comparisons of results obtained within and between capillary arrays; evaluation of capillary length; evaluation of sample injection time; evaluation of the resolution of mixtures/heteroplasmic samples; and evaluation of the sensitivity of detection of a minor component with reduced template on the ABI 3100. In addition, other studies were performed to improve sample preparation; these included: comparison of template suppression reagent (TSR, Applied Biosystems, Foster City, CA) versus formamide; the use of Performa DTR Gel Filtration Cartridges (Edge BioSystems Inc., Gaithersburg, MD) versus Centri-Sep Spin Columns (Princeton Separations, Adelphia, NJ) for product purification after cycle sequencing; and sample stability after denaturation. The data support that valid and reliable results can be obtained using either capillary electrophoresis instrument, and the quality of sequencing results are comparable to or better than those obtained from the ABI 377 instrument.  相似文献

Although much research exists regarding the transition into junior high school, surprisingly few studies have focused on the move into high school. The present study employed a short-term longitudinal design to assess the adjustment of adolescents as they made the transition from junior high to high school. Changes in adolescents' sense of autonomy, perceived stressors, social support, sense of school membership, grade point average (GPA), and attendance were assessed. Coping strategies were also considered at each time point. Also, because parents who feel better about themselves may offer more support to their adolescents, parents of the adolescents in the study completed measures assessing their stressors and coping mechanisms. Results indicated that the adolescents did experience significant changes during the initial transition into high school that were related to GPA and sense of school membership. Perceived support from parents was also related to adolescents' adjustment to the transition. The study bridges a gap in the literature on school transitions by addressing the transition to high school in light of adolescent and parent variables. Implications for practices by school personnel and future research suggestions are provided.  相似文献

This investigation specified three models regarding the association between identity and intimacy formation and investigated their potential validity using a longitudinal cross-lag panel design. Seventy-one males and 71 females completed identity and intimacy measures on two occasions over a 5-week period. The primary findings are (1) individuals with a clear sense of identity are more likely, 5 weeks later, to have a more advanced sense of intimacy for both sexes when sex-role identification is removed from gender comparisons; (2) sex-role orientation mediates the identity/intimacy association, while for females, a masculine orientation is associated with a pattern similar to that observed for either masculine- or feminine-oriented males; and (3) femininity is associated with a more fused connection between identity and intimacy for females. This report provides an initial investigation studying the identity/intimacy association during late adolescence based on three theoretical perspectives. Theoretical interpretations and conclusions are offered.Partial support for this project was provided by grants to the second author from the Utah State University Agricultural Experiment Station and the Office of Research, Utah State University. Approved as journal paper No. 3917.Research interests are adolescent identity development in the family context, adolescent sexuality, and sex-role development.Research interests focus on personality and social development during adolescence.  相似文献

Dominance in the peer group is important for adolescents. Resource Control Theory posits that both coercive and prosocial (positively assertive) strategies are associated with dominance. Combining Resource Control Theory with Socioanalytic Theory on personality, we hypothesized that inspiring group members would be an additional effective strategy. This study examined whether the three behavioral strategies and two types of social skills (social competence and manipulation) predicted dominance (resource control and popularity). Participants were 619 Dutch adolescents (Mage?=?13.1; 47% female) in the first grade of secondary school. They completed peer reports (behavioral strategies and dominance) and self-reports (social skills). Only inspirational and coercive strategies substantially predicted dominance. Main effects of social skills emerged. Moderation between strategies and social skills was only observed for girls (e.g., coercive strategy use was associated with more popularity for girls with higher levels of social manipulation skills). This study furthered our understanding of the predictors of dominance in adolescence by including inspirational behavior and examining prosocial and antisocial skills.  相似文献

In the absence of party labels, voters must use other information to determine whom to support. The institution of nonpartisan elections, therefore, may impact voter choice by increasing the weight that voters place on candidate dimensions other than partisanship. We hypothesize that in nonpartisan elections, voters will exhibit a stronger preference for candidates with greater career and political experience, as well as candidates who can successfully signal partisan or ideological affiliation without directly using labels. To test these hypotheses, we conducted conjoint survey experiments on both nationally representative and convenience samples that vary the presence or absence of partisan information. The primary result of these experiments indicates that when voters cannot rely on party labels, they give greater weight to candidate experience. We find that this process unfolds differently for respondents of different partisan affiliations: Republicans respond to the removal of partisan information by giving greater weight to job experience while Democrats respond by giving greater weight to political experience. Our results lend microfoundational support to the notion that partisan information can crowd out other kinds of candidate information.  相似文献

Abstract

Twenty-five years ago, as preferential trade agreements started to proliferate, Jagdish Bhagwati sounded the ‘spaghetti bowl’ alarm, arguing that the ensuing complexity would create inefficiencies in the international system and challenges for firms navigating overlapping rules. This article seeks to update and complement Bhagwati’s thesis by asking if proliferating ‘deep’ trade agreements add a new dimension of complexity to this picture. This article shows that the early answer to this question is ‘not yet’, as governments have discovered that prospective conflicts with existing or simultaneous commitments limit just how deep the provisions of an agreement can be. Governments managing multiple deep agreements play a variation on Putnam’s two-level game. As Putnam theorized, these governments reconcile domestic interests with international opportunities in formulating their strategies. However, ensuring compatibility across various, sometimes competing international opportunities is also a key consideration. Canada’s concurrent participation in the Trans-Pacific Partnership (TPP) and the Canada–European Union Comprehensive Economic and Trade Agreement (CETA) provides a crucial exploratory case study.  相似文献
