High-quality digital three-dimensional (3D) reconstructions of microscopic findings have been used in anatomical and histopathologic research, but their use in forensic pathology may also be of interest. This paper presents an application of these methods to better characterize the pathway of a stab wound of the anterior surface of the heart in a case of suicide. A portion of the heart wall including the stab wound was serially sectioned for microscopic analysis along the full extent of the wound. Histologic sections were digitally acquired, and a 3D reconstruction was created with ImageJ software for 3D computer graphics. This showed a full-thickness wound path extending to the endocardial surface of the left ventricle, curvilinear in appearance. After correction for shrinkage, 3D reconstruction allowed estimation of the dimensions of the myocardial injury and comparison of the appearance of the wound with the suspected knife used. The curvilinear appearance was considered to reflect injury during myocardial contraction. Complete microscopic sectioning and 3D reconstruction may allow virtual sectioning through various orientations and also provide useful forensic information for selected injuries. 相似文献

Dating in adolescence plays an integral part in the development of sexual and social identities. This process is particularly
salient for sexual minority youth who face additional obstacles to their identity formation due to their marginalized status.
We investigated the influence of participating in a same-sex relationship (SSR) or an opposite-sex relationship (OSR) on sexual
minority youths’ psychological well-being (i.e., symptoms of depression, anxiety and internalized homophobia, and self-esteem)
in an ethnically-diverse sample of 350 youth (55% male) between the ages of 15–19 years, recruited from three GLBT drop-in
centers in the New York City area. Using longitudinal data, we examined youths’ SSR and OSR over time. Multivariate regression
analyses suggest that involvement in a SSR was positively associated with changes in self-esteem in males, and negatively
correlated with changes in internalized homophobia in females. We discuss the implications for positive development in sexual
minority adolescent populations. 相似文献

The study purpose was to assess the impact of public sector audit on investment climate formation under the COVID-19 pandemic and to develop recommendations to improve its effectiveness. For this purpose, a multistage research project was developed with the participation of auditors from Russia, Kazakhstan, and Ukraine. The project was based on the primary information obtained in the course of expert interviews. Testing the methodological approach with experts from these countries allowed proving the main study hypotheses, according to which the public sector audit has an indirect positive impact on investment climate formation. Such an audit influences the main impact factors through improving public administration efficiency, the fight against corruption, and the provision of the regulatory framework. During the testing, the main directions for improving public audit for a more favorable investment climate were formulated. The developed methodological approach makes it possible to obtain an expert assessment of the impact of the public audit on investment climate formation. At the same time, partial use of statistical methods makes it possible to replicate the study in the form of an expert interview, which increases its attractiveness for researchers in conditions of shortage of qualified interviewers. 相似文献

A fraction of SIDS cases have death delayed by successful CPR, yet they have not been compared to SIDS cases which were found dead or not successfully resuscitated. Our aims were to: (1) determine the percent of SIDS cases in the San Diego SIDS Research Project database for whom death was delayed by CPR and subsequent life support; (2) compare demographics, circumstances of death and autopsy findings of delayed death SIDS cases (delayed SIDS) with those whose deaths were not delayed (non-delayed SIDS); (3) examine the evolution of pathologic changes in delayed SIDS as a function of survival interval. A retrospective 15-year population-based study of 454 infant deaths attributed to SIDS revealed 29 delayed SIDS cases (Group I) and 425 non-delayed SIDS cases (Group II). Group I cases were significantly older than Group II cases (mean age 132 days vs. 102 days and p<0.0001). Eighty-nine percent of the Group I cases were discovered between 08.00 and 19.59 h; none were found between 00.00 and 07.59 h, compared to 38% of the Group II cases. Group I infants were found significantly more often away from home (at daycare, or at the home of a relative, friend, or baby sitter) than Group II infants (45% vs. 25%, p<0.05). There were no differences between groups with regard to gender, gestational age, type of delivery, bed sharing, URI within 48 h of death, ALTEs, a history of referral to child protective services, body position when placed or found, or face position when found. Pathologic changes were semiquantitatively evaluated; findings were characteristic of anoxic-ischemic injury that generally became more severe with increasing survival intervals. Anoxic-ischemic brain injury was the immediate cause of death in all delayed SIDS cases. Aspiration of gastric contents was identified in Group I cases surviving less than 48 h and was the likely etiology of acute bronchopneumonia occurring in 83% of the Group I cases. We did not identify factors that would reliably predict which SIDS cases might be discovered soon enough to allow earlier and more effective CPR and survival without permanent brain injury. 相似文献

ABSTRACTThe returned Australia-Japan Foundation Visiting Professor of Australian Studies at the University of Tokyo (2014–15), Anna Johnston, reflects on a 2014 exhibition held in Tokyo: The Bunkamura Museum of Art’s “Captain Cook’s Voyage and Banks’ Florilegium.” The Florilegium continues to have resonance as part of Australia’s complex colonial inheritance from the Enlightenment past. Its display and interpretation both overseas and within Australia provides an opportunity to better understand its origin in a pivotal historical period, globally, and its contribution to knowledge in arts and sciences. The Florilegium also reveals how Indigenous knowledge was central to European exploration and knowledge production. This article outlines contextual issues and seeks to provide a complex biography of this scientific and artistic artefact of Empire, in order to propose new ways of reading the Florilegium that pay attention to that enriched biography. 相似文献

Thirty-nine adolescent girls, 16–19 years, were observed together with their 2 parents at a family discourse about moral and family issues on which they disagreed, to study interaction and conflict handling in families with daughters at different levels of ego development. Family interactions were coded by the Constraining and Enabling Coding System, ego development by the Washington University Sentence Completion Test and handling of internal conflict by Bond Defense Style Questionaire. Daughters' ego development was predicted by parental cognitive and affective enabling, but not by constraining communications. Fathers' cognitive and affective enabling transactions and mothers' affective enabling transactions contributed to the explained variance in the adolescents' ego development when daughters' age, parents' SES and ego development were controlled for in hierarchical regression analyses. Parents' ego levels were related to their enabling transactions, which also predicted daughters' ego levels, suggesting that especially enabling parenting behavior may play a mediating role. Mothers' challenging behavior toward daughters and parental autonomy from responding in kind to daughters' communications were also related to high ego levels in daughters. 相似文献

Lecturers in feminist theory come face to face with the gender order when giving a lecture, which is expressed by preconceptions about feminism. A model, the Cloud, is presented in this article which can be used to improve teaching and increase the chances of constructive dialogue. By bringing preconceptions into the open and analysing them, these ideas can be made to illuminate the presentation, not to hinder it. As a general model the Cloud is a tool that will help us to articulate common beliefs about phenomena to make way for knowledge based on research. 相似文献
