Objective

This study sought to examine the impact of two Teen Courts operating in Los Angeles County, a juvenile justice system diversion program in which youths are judged by their peers and given restorative sentences to complete during a period of supervision.

Methods

A quasi-experimental design was used to compare youths who participated in Teen Courts (n = 112) to youths who participated in another diversion program administered by the Probation Department (the 654 Contract program) (n = 194). Administrative data were abstracted from the probation records for all youths who participated in these programs between January 1, 2012 and June 20, 2014. Logistic and survival models were used to examine differences in recidivism, measured as whether the minor had any subsequent arrest or arrests for which the charge was filed.

Results

Comparison group participants had higher rates of recidivism than Teen Court participants, after controlling for age, gender, race/ethnicity, and risk level. While the magnitude of the program effects were fairly consistent across model specifications (odd ratios comparing Teen Court [referent] to school-based 654 Contract ranging from 1.95 to 3.07, hazard ratios ranging from 1.62 to 2.27), differences were not statistically significant in all scenarios.

Conclusions

While this study provides modest support for the positive impact of Teen Court, additional research is needed in order to better understand how juvenile diversion programs can improve youth outcomes.

Abstract:  In forensic pathology and anthropology, a correct analysis of lesions on soft tissues and bones is of the utmost importance, in order to verify the cause and manner of death. Photographs, videos, and photogrammetry may be an optimal manner of immortalizing a lesion, both on cadavers and skeletal remains; however, none of these can supply a detailed three-dimensional (3D) modeling of the lesion. Up to now, only the use of casts has given us the possibility of studying deep lesions such as saw marks with an accurate and complete 3D reconstruction of bone structure. The present study aims at verifying the applicability of 3D optical contactless measurement for the accurate recording of soft tissue and bone lesions, in order to develop a unique and precise method of registering and analyzing lesions, both in forensic pathology and anthropology. Three cases were analyzed: the first, a car accident with blunt force skin injuries; the second, a murder with blunt force injury to the head applied with a metal rod; the third, a series of sharp force knife and saw lesions on bone. Results confirm that 3D optical digitizing technology is a crucial tool in the immortalization of wound morphology in the medico-legal context even on "difficult" substrates such as cut marks and saw marks on bone.  相似文献

Building on a handful of studies demonstrating battered women’s accuracy in assessing their risk of being physically reabused, this study examined how accurately victims assess their risk of future psychological abuse. Participants’ ratings of the likelihood that their partner would engage in controlling/dominance behaviors or efforts to humiliate/degrade them in the coming year and their reports 18 months later of whether this had actually occurred were used to create a four category version of accuracy (true positive, false positive, true negative, false negative). Victims were more likely to be right than wrong in their assessments of risk; PTSD symptoms, the recency of physical violence, and the degree of stalking and psychological abuse in the relationship predicted membership in the four accuracy categories. These findings overlap considerably with those examining victim accuracy in predicting physical abuse and inform ongoing debates about the value of incorporating victims’ insights into risk assessment efforts.

This study explored the relationship between Intimate Partner Violence and HIV Risk-Propensity in African-American women. An anonymous questionnaire was completed by a community based sample of 200 African American women with a varied history of intimate partner violence, to determine whether being in a violent relationship impacts HIV risk. Various statistical techniques, including structural equation modeling (SEM), bivariate correlation analyses and ANOVA were used to examine the data. A strong positive correlation was found to exist between sexual coercion and Intimate Partner Violence. In the effort to fortify prevention strategies, and reduce the rates of HIV infection in African-American women, additional factors that impact disease transmission were discussed. Implications for social work/mental health practice and suggestions for future research were made.  相似文献

Child abuse pediatricians often carry the stigma that their sole role is to diagnose maltreatment. In reality, child abuse pediatricians use their clinical experience and current evidence-based medicine to make the best medical diagnoses for the children they evaluate. To better understand the legal conclusion of suspected maltreatment cases with medical examinations, this study sought to: (i) evaluate the percentage of children seen for suspected maltreatment that led to a clinical diagnosis of maltreatment, (ii) determine the number and type of criminal charges associated, and (iii) analyze the legal outcomes of cases as they proceeded through the judicial system. This study retrospectively reviewed the legal outcomes of 1698 children medically evaluated in 2013–2014 as part of an investigation by a multidisciplinary team at a children’s advocacy center in a mid-sized city in Oklahoma. Data were collected from electronic medical records, the district attorney’s office, and a public court docket. Of the original cohort, 477 (28.09%) children yielded a medical diagnosis of at least one type of maltreatment. Further analysis yielded 115 unique court cases involving 138 defendants and 151 children. A total of 286 charges were filed resulting in 190 convictions. While maltreatment allegations yield a high number of children that must be evaluated, a comprehensive medical evaluation helps determine which cases do not have sufficient medical findings for a diagnosis of maltreatment. The findings in this study indicate that a majority of suspected maltreatment cases seen by child abuse pediatricians did not result in criminal court outcomes.  相似文献

Better understanding of the timing of fracture healing may help in cases of interpersonal violence but also of personal identification. The intra- and inter-rater agreement for the adapted fracture healing scale (AFHS) assessing the post-traumatic time interval on radiographs were tested. This is a preliminary study, providing essential information on method reliability for upcoming studies using the AFHS. Five raters (two radiologists, a forensic pathologist, an orthopedist, and an anthropologist) were presented with a test in three parts consisting of 85 radiographs (from 30 adults) of fractures of tubular bones in different stages of healing purposefully selected from more than 1500 radiographs. The raters were firstly asked to assess 15 features describing fracture healing as present, absent, or not assessable. Thereafter, the raters were asked to choose from the AFHS a single-stage best representing the observed healing pattern. The intra- and inter-rater agreement were assessed using single-rating, absolute agreement, two-way mixed-effects intra-class correlation (ICC) coefficients. The intra-rater ICC of radiologist 1 ranged from 0.80 to 0.94. The radiologists’ inter-rater ICC ranged from 0.68 to 0.74, while it ranged from −0.01 to 0.90 for the other raters. The good to excellent ICC among the radiologists and forensic anthropologist provides good foundation for the use of the AFHS in forensic cases of trauma dating. The poor to good results for the other physicians indicate that using the AFHS requires training in skeletal anatomy and radiology.  相似文献

This paper explores how four young women narrated accounts of their interactions with their male peers in the engineering classroom. Drawing on data collected in a qualitative case study conducted at one high-performing English university, this paper details how the four women described two different versions of laddish masculinity evident within their engineering classroom; a hostile laddish masculinity, and a ‘friendly’ or ‘genial’ upper/middle-class laddish masculinity. Whilst the hostile lads were seemingly frowned upon and socially excluded, the ‘friendly’ or ‘genial’ upper/middle-class lads appeared largely liked and tolerated by the women. This paper thus adds to our understanding of women’s current experiences in engineering education, and works to extend research in the area of laddism in formalized learning contexts in higher education (HE). In particular, this paper draws attention to the existence of subtle or nuanced degrees of laddism in engineering at the university under study, and highlights a possible relationship between ‘lad’ discourses and gendered disciplinary discourses.  相似文献

On 1 April 2015, 11 Atlanta teachers accused of changing answers on their students’ standardized tests were convicted of racketeering and sentenced to 5–20 years in prison. Despite ample news coverage, few sources investigated teachers’ motivations for altering students’ responses or explored what the consequences would have been if student scores had not been changed to passing. Moreover, the fact that the teachers’ actions resulted from systemic problems associated with working within a high-stakes testing environment is glossed over and all but lost in the reporting of the “Cheating Scandal” events. The authors conduct a critical multimodal analysis of how semiotic resources were used to represent teachers in the Atlanta “Cheating Scandal” and show how the media's framing of teachers both reflects and conceals specific interests of the powerful educational reform movement and the corporations that benefit from it, such as Pearson, Inc. Data sources included four online news sources from April 2015 that covered the teachers’ sentencing, and the authors analyzed the visual and verbal transformations that occurred during the process of recontextualization. Analysis revealed the construction of a moral narrative that depicted the teachers as selfish and incompetent, reinforcing the dominant paradigm driving school reform in the USA. The authors conclude by calling for more counter-narratives that expose how dominant representations reify negative public perceptions of teachers.  相似文献
