Spontaneous cerebellar hemorrhages are a rare but often fatal occurrence in children. Although there are several predisposing factors such as blood dyscrasias or astrocytomas, the most common cause of cerebellar hemorrhage in an otherwise healthy child is the rupture of a vascular malformation. We reviewed the files of the Office of Chief Medical Examiner of the City of New York and found four such instances over a period of less than two years. We present these here and outline the approach the forensic pathologist should take in evaluating such deaths. 相似文献
Surveys with 94 administrators of supervised visitation programs, 51 family court judges, and 40 administrators of child protective services agencies provide a national picture of supervised visitation services, their utility, and areas of unmet need. Although the programs are perceived to fill an important need, they struggle to survive financially, particularly those that handle family court cases. In addition, because many programs operate without adequate access to the assessment and treatment services that some families need, judges frequently want visitation supervisors to assist them in determining suitable custody and visitation arrangements, a role that supervised visitation programs do not feel is appropriate. Many different types of entities provide effective supervised visitation services; many different service formats work. Architects of new programs should fashion services that use local resources to maximum advantage. 相似文献
This article identifies and describes the development of three parallel streams of literature about network theory and research: social network analysis, policy change and political science networks, and public management networks. Noting that these traditions have sometimes been inattentive to each other's work, the authors illustrate the similarities and differences in the underlying theoretical assumptions, types of research questions addressed, and research methods typically employed by the three traditions. The authors draw especially on the social network analysis (sociological) tradition to provide theoretical and research insights for those who focus primarily on public management networks. The article concludes with recommendations for advancing current scholarship on public management networks. 相似文献

Three commercially available integrated rapid DNA instruments were tested as a part of a rapid DNA maturity assessment in July of 2018. The assessment was conducted with sets of blinded single-source reference samples provided to participants for testing on the individual rapid platforms within their laboratories. The data were returned to the National Institute of Standards and Technology (NIST) for review and analysis. Both FBI-defined automated review (Rapid DNA Analysis) and manual review (Modified Rapid DNA Analysis) of the datasets were conducted to assess the success of genotyping the 20 Combined DNA Index System (CODIS) core STR loci and full profiles generated by the instruments. Genotype results from the multiple platforms, participating laboratories, and STR typing chemistries were combined into a single analysis. The Rapid DNA Analysis resulted in a success rate of 80% for full profiles (85% for the 20 CODIS core loci) with automated analysis. Modified Rapid DNA Analysis resulted in a success rate of 90% for both the CODIS 20 core loci and full profiles (all attempted loci per chemistry). An analysis of the peak height ratios demonstrated that 95% of all heterozygous alleles were above 59% heterozygote balance. For base-pair sizing precision, the precision was below the standard 0.5 bp deviation for both the ANDE 6C System and the RapidHIT 200. 相似文献
This report interprets the presence of mite species in three clandestine graves in Europe, evaluating their potential use as trace evidence or markers. Grave 1 (Sweden): Two mite species Rhizoglyphus robini Claparède, 1869 and Parasitus loricatus (Wankel, 1861) were recovered from the surface of a body buried in a shallow grave in an area surrounded by trees, in close vicinity to house gardens. Grave 2 (Germany): Phoretic deutonymphs of Gamasodes spiniger (Trägårdh, 1910) were attached to an adult fly (Diptera: Sphaeroceridae) found within a shallow grave containing two human bodies covered in soil and dung. Grave 3 (France): P. loricatus were recovered from the soil around a body buried in a deep grave (80 cm under). In graves 1 and 3 both corpses were undergoing advanced decay and skeletization, the locations match with the subterranean habit of P. loricatus, highlighting the value of this species as a marker of graves or burials in soil and during late decomposition. R. robini is a soil mite that feeds on decayed roots and bulbs; this mite species confirms the location of the corpse within top soil, agreeing with a more specific type of superficial burial, a shallow grave. In case 2, the presence of both coprophiles, the mite G. spiniger and the carrier fly confirm association of remains with dung or animal feces. The three mite species are reported for the first time in human graves. There are no previous records of R. robini from Sweden. 相似文献
Critics of neoliberalism argue that so-called meritocratic and identity-neutral social policies and political positions actually reinforce and exacerbate intersecting inequalities, namely racism, sexism, heterosexism, classism, and ethnocentrism/xenophobia. The purpose of these studies was to develop and initially validate a scale of neoliberal attitudes from a wide range of existing instruments that reflect anti-neoliberal theory. A series of three studies resulted in a 25-item instrument—the Anti-Neoliberal Attitudes Scale (ANAS)—that exhibits initial evidence of construct validity, internal consistency, and test–retest reliability. Exploratory factor analysis with students from two universities revealed a four-factor structure of Racism and Sexism Awareness, Communitarian Values, Multicultural Ideology, and Inequality Consciousness. However, a confirmatory factor analysis with an independent sample of undergraduate students suggests a bifactor model in which the general factor explains most of the variance and that the instrument should be treated as a single scale, rather than independent subscales. Significant correlations with measures of right-wing authoritarianism and social dominance orientation suggest convergent validity. Temporal stability was established via a test–retest analysis in an independent sample of undergraduate students. Finally, responses from a sample of MTurk workers provided evidence of the ANAS’s incremental validity when compared to an existing measure of neoliberal beliefs. Implications for future empirical work on the psychological dimensions of neoliberalism are discussed.
The role of older siblings in younger siblings’ academic socialization becomes increasingly salient during adolescence. This longitudinal study examines the developmental mechanisms through which older siblings shape younger siblings’ academic outcomes and whether older siblings’ peer affiliations predict younger siblings’ educational aspirations and attainment. Data consisted of responses from 395 target adolescents (Mage?=?12.22 years, 48.9% female; 51.6% African American, 38.5% European American) and their older siblings (Mage?=?14.65 years, 50.1% female) across nine years. The findings showed that older siblings’ affiliation with academically disengaged peers at 7th grade predicted younger siblings’ decreased affiliation with academically engaged peers and increased affiliation with disengaged peers at 9th grade. In addition, younger siblings’ affiliation with academically engaged peers predicted greater educational aspirations at 11th grade, which in turn were related to higher postsecondary educational attainment. The identification of developmental processes through which older siblings were associated with younger siblings’ academic success may aid in creating supportive social environments in which adolescents can thrive.
Peer relationships undergo dramatic shifts in form and function during adolescence, at the same time the incidence of socially evaluative fears sharply rises. Despite well-established links between social anxiety and broader interpersonal functioning, there is a dearth of research evaluating the impact of social anxiety on functioning in close relationships during this developmental stage. The present study examines the impact of social anxiety on functioning in close friendships and romantic relationships during adolescence. From a developmental psychopathology perspective, it was expected that social anxiety would influence functioning (quality, length, satisfaction) in romantic relationships through its influence on functioning in same- and other-sex friendships. Participants included 314 adolescents (60.5 % female, 14–19 years of age) with a prior or current history of romantic relationship involvement. Structural equation modeling was used to test a mediation model positing an indirect pathway from social anxiety to romantic relationship functioning through functioning in close same- and other-sex friendships. Given known gender differences in social anxiety and relationship functioning, gender also was explored as a potential moderator. Results supported the hypothesized indirect pathway whereby social anxiety was associated with impairment in same-sex friendships; functioning in same-sex friendships was associated with functioning in other-sex friendships, which was associated, in turn, with functioning in romantic relationships. While the hypothesized indirect pathway was significant among both boys and girls, there was greater continuity of functioning between same- and other-sex friendships for girls. These findings highlight the importance of examining the multiple downstream effects of social anxiety on perceived social functioning in adolescence, and suggest that continuity may exist for maladaptive patterns of socialization, particularly across developmentally salient close relationships. 相似文献
Much of the writing on gender and the First World War has looked at the ways in which pre-war gender norms were reasserted in British society after the War. The article looks at the experiences of one group of women, the wives of men psychologically disabled by the experience of war, to show how disability could prevent the reassertion of pre-war gender roles. The experiences of these women, as expressed in the disability files created by the Ministry of Pensions, is then compared with the dramatisations of wives of disabled veterans in two post-war novels. This comparison highlights the ways in which such dramatisations turned the figure of the wife of the disabled veteran into a symbol of suffering that may be compared to the similarly symbolic figures of the neurasthenic veteran. 相似文献
