Peritonitis secondary to spontaneous rupture/perforation of the gall bladder is a rare condition overall and is even less common in the forensic population. We report the case of a middle‐aged man who died from generalized peritonitis from gall bladder perforation due to acute acalculous cholecystitis. This condition usually occurs in critical patients with systemic illness, and although the exact pathogenesis remains unclear, the development of acalculous cholecystitis appears to be multifactorial. Antemortem diagnosis is reliant upon clinical presentation, laboratory data, and radiologic studies. Surgery and appropriate antibiotics are mainstays of treatment; however, there is an emerging role for minimally invasive procedures. Histopathologic features show significant overlap with the calculous type. Although increasing numbers of acalculous cholecystitis have been diagnosed in the critically ill, the fatal presentation of a perforated gall bladder following an undiagnosed case of acute acalculous cholecystitis is unusual in a nonhospitalized and ambulatory man.  相似文献

Restorative justice (RJ) holds significant potential as a means for nurturing relational school cultures and addressing harm within those contexts. However, educators participating in professional development (pd), often articulate a commitment to RJ in principle but tend to continue practicing a pedagogy that focuses on controlling student (mis) behavior apart from its relational context. Considering the strong philosophical perspective of humanity on which RJ is grounded, this phenomenological case study examines the impact of pd that explicitly (a) engages with core beliefs and values of RJ and (b) invites participants to examine their personal philosophical stance. Employing theory-guided analysis and poetic inquiry to examine participants’ reflections nine months following their experience, results indicate that commitment and practice are better aligned. A significant change in perspectives emerges self; others; current practice; and group engagement. A list of recommended components for professional development concludes the article.  相似文献

As the closed-circuit television (CCTV) security industry transitioned from analog media to digital video recorders (DVRs) with digital storage, the law enforcement community struggled with the means with which to collect the recordings. New guidelines needed to be established to determine the collection method which would be efficient as well as provide the best quality evidence from live DVRs. A test design was developed to measure, quantify, and rank the quality of acquisition methods used on live systems from DVRs typically used in digital CCTV systems. The purpose was to determine guidelines for acquiring the best quality video for investigative purposes. A test pattern which provided multiple quantifiable metrics for comparison between the methods of acquisition was used. The methods of acquisition included direct data download of the proprietary file and open file format as well as recording the video playback from the DVR via the available display monitor connections including the composite video, Video Graphics Array (VGA), and high-definition multimedia interface (HDMI). While some acquisition methods may provide the best quality evidence, other methods of acquisition are not to be discounted depending on the situation and need for efficiency. As an investigator that needs to retrieve video evidence from live digital CCTV systems, the proprietary file format, overall, provides the best quality evidence. However, depending on the circumstance and as recording technology continues to evolve, options other than the proprietary file format may provide quality that is equal to or greater than the proprietary file format.  相似文献

Despite the veritable influence of the peer context on the elaboration of adolescent aggression, few studies of relational aggression have directly identified and measured peer groups, limiting our ability to draw formal conclusions about the level and nature of peer influence. The current study used a developmental framework to examine peer group influence on individual levels of physical and relational aggression over a year with 6th and 7th grade students (n = 346, 51 % female). A multilevel network approach was used in which peer groups were identified via social network analysis, and peer group influence was evaluated with hierarchical linear modeling (HLM). HLM analyses indicated that peer group aggression (physical and relational) at time 1 was predictive of individual aggression levels at time 2 after controlling for other peer group characteristics as well as other individual risk and protective factors. Although both forms of aggression were embedded in peer networks, findings suggest that physical aggression is relatively less endemic to peer networks, and is more likely to occur in smaller, predominantly male networks. The current study highlights the importance of understanding the influence of peer group membership on adolescent aggression and points to important implications for prevention.  相似文献

Lesbian, gay, and bisexual students (LGB) and those questioning their sexual orientation are often at great risk for negative outcomes like depression, suicidality, drug use, and school difficulties (Elliot and Kilpatrick, How to Stop Bullying, A KIDSCAPE Guide to Training, 1994; Mufoz-Plaza et al., High Sch J 85:52–63, 2002; Treadway and Yoakam, J School Health 62(7):352–357, 1992). This study examined how school contextual factors such as homophobic victimization and school climate influence negative outcomes in LGB and questioning middle school students. Participants were 7,376 7th and 8th grade students from a large Midwestern county (50.7% Female, 72.7% White, 7.7% Biracial, 6.9% Black, 5.2% Asian, 3.7% Hispanic, and 2.2% reported “other”). LGB and sexually questioning youth were more likely to report high levels of bullying, homophobic victimization, and various negative outcomes than heterosexual youth. Students who were questioning their sexual orientation reported the most bullying, the most homophobic victimization, the most drug use, the most feelings of depression and suicidality, and more truancy than either heterosexual or LGB students. A positive school climate and a lack of homophobic victimization moderated the differences among sexual orientation status and outcomes. Results indicate that schools have the ability to lessen negative outcomes for LGB and sexually questioning students through creating positive climates and reducing homophobic teasing.  相似文献

This study tested a social-ecological model of adolescent substance use. Multilevel modeling was used to investigate how systems, such as parents, peers, schools, and communities, directly influence and interact together to influence adolescent substance use. Participants included 14,548 (50.3% female) middle school students who were 78.6% White, 5.4% Biracial, 4.8% Asian, 4.8% Black, and 3.6% Hispanic. Participants completed a survey with scales assessing substance use, peer influences, parental influences, and characteristics of their school and community. Hierarchical linear modeling (HLM) was used to consider the variation of parental and peer influences on substance use and how schools and communities relate to both substance use and the relationship between substance use and peer and parental factors. Results indicated that a positive school climate and a positive sense of community were associated with less adolescent substance use and that a positive sense of community moderated the relation between peer and parental influence on adolescent substance use, thereby acting as a protective factor.

Using survey data from Miami, Florida, this study empirically tests whether racial mistrust is related to a willingness to engage in delinquent behaviors among a sample of African Americans, Haitians, and other Caribbean Island Black adolescent boys residing in Miami, Florida. No significant differences were found among the three groups with respect to their disposition scores. However, when compared to non-Blacks, African Americans and Haitians reported a greater willingness to violate the law. Bivariate analyses suggest a strong relationship between racial mistrust and disposition to deviance for all three ethnic groups. Three findings also held in multivariate analyses controlling for socioeconomic status.  相似文献

Reasonable expectation of privacy is discussed in the context of searches conducted without the warrants usually required by the Fourth Amendment but with the consent of a third party, who is not the target of the search. Case law on this issue is neither consistent nor clear-cut. Psychological theory and research clarify this issue by establishing closer correspondence between legal concepts and assumptions and individuals' actual behaviors and social expectations. The key legal components of reasonable expectation of privacy are delineated, with regard to third-party consent: “common authority” areas versus “exclusive use” areas and theassumption of risk doctrine. Next, the psychological theory and research on interpersonal relations and human territorial functioning are reviewed as they relate to the legal components of privacy regulation. Taken together, the legal criticisms of this warrant exception category, and possible discrepancies between the legal assumptions concerning interpersonal and territorial functioning among co-residents and the actual behaviors and expectations suggested by psychological theory and research, raise questions about its validity.  相似文献

Public and business sector organizations are the primary subjects of the existing literature on organization termination. This article considers the applicability of the termination literature to the nonprofit organization context. In particular, the literatures of public administration (public agency termination), organization theory (life cycles of organizations), and business administration (firm failure) are used to examine the termination experience of a specific nonprofit agency, Children's Rehabilitation Services (CRS). After more than thirty years of providing residential treatment services to boys with emotional problems, the agency merged with another nonprofit rather than face bankruptcy. To understand the causes of CRS's termination, financial factors, deleon's (1978) obstacles to termination, life cycle theory and the role of the agency's changing environment are studied. The case of CRS illustrates many of the findings of the organization termination literature and introduces a new point essential to consideration of termination in the nonprofit context: the importance of the selection of decision makers with competencies appropriate for the given life cycle stage of the organization.  相似文献
