Forensic fractographic features of bone reliably establish crack propagation in perimortem injuries. We investigated if similar fracture surface features characterize postmortem fractures. Experimentally induced peri- and postmortem fractures were used to assess if fractographic features vary as bone elasticity decreases during the postmortem interval (PMI). Thirty-seven unembalmed, defleshed human femoral shafts from males and females aged 33–81 years were fractured at varying PMIs with a drop test frame using a three-point bending setup and recorded with a high-speed camera. Vital statistics, cause of death, PMI length, temperature, humidity, collagen percentage, water loss, fracture energy, and fractography scores were recorded for each sample. Results showed that fractographic features associated with perimortem fractures were expressed in PMIs up to 40,600 accumulated degree hours (ADH), or 60 warm weather days. Hackle was the most consistently expressed feature, occurring in all fractures regardless of ADH. The most variable characteristics were wake features (78.4%) and arrest ridges (70.3%). Collagen percentage did not correlate strongly with ADH (r = −0.04, p = 0.81); however, there was a strong significant correlation between ADH and water loss (r = 0.74, p < 0.001). Multinomial logistic regression showed no association between fractographic feature expression and ADH or collagen percentage. In conclusion, forensic fractographic features reliably determine initiation and directionality of crack propagation in experimentally induced PMIs up to 40,600 ADH, demonstrating the utility of this method into the recent postmortem interval. This expression of reliable fractographic features throughout the early PMI intimates these characteristics may not be useful standalone features for discerning peri- versus postmortem fractures. 相似文献

School can be regarded as an important factor in the development of children’s values and attitudes. Given this great importance of justice experiences for students’ development, this study aimed at examining the influence of perceived injustice in school on students’ emotions, well-being, and behavior with an experimental longitudinal design. In total, 196 students participated in this study and came to the university with their classes to receive extra teaching once a week for six consecutive weeks. To manipulate justice perceptions, a scenario of arbitrary privilege was chosen to lead students of the experimental group to experience injustice from a beneficiary perspective. We found that students in the experimental group reported higher well-being and a higher appreciation of the opportunity to learn than the control group did. Additionally, they showed an increase in justice-related negative emotions over time; that is, they expressed more of a bad conscience and stronger feelings of anger the more they became aware of their privilege. This study shows that even subtle experiences of injustice in school can have an impact on students’ outcomes. These results are discussed with regard to practical implications. 相似文献

Encountering the criminal justice system at the first point of entry---an arrest---is associated with heightened HIV and Hepatitis risk behavior among people who inject drugs (PWIDS). Intervening structurally through the criminal justice system impacts public health; therefore, determining arrest patterns is an important tool for risk reduction. Among a sample of 740 PWIDs, and their social network members recruited from predominantly African-American neighborhoods in Baltimore City, a third were recently arrested in the previous six months, and of those, the arrests were disproportionately African-American persons and characterized as nonviolent, i.e., drug possession/attempt to purchase (38%) and loitering (29%). Poisson regression models were built adjusted for age, sex, race, education level, homelessness, and monthly income after exploring bivariable characteristics of arrests using chi-squared tests. Active drug use was associated with a recent arrest (adjusted prevalence ratio: aPR 2.38 95% CI 1.6, 3.6), in addition to participants who recently reported attending a syringe exchange program (aPR 1.45 95% CI 1.1, 2.0). Our findings are suggestive of recent media coverage and burgeoning research revealing the prioritization of policing resources toward both communities of color and neighborhoods of intensified drug trafficking. Further research is warranted to contextualize the operationalization of criminal justice resources and the impact on community health. 相似文献

Background: Routine assessment of individual change in forensic mental health services is increasingly recognised as important. However, existing tools have been criticised and their periodic use make them unsuited to directly measure the impact of interventions. This paper describes the initial evaluation of the Global Review Form (GRF) as a framework for measuring change over time. Specifically, measurement properties, feasibility and usefulness in routine practice are examined. Method: 28 male service users in three distinct areas of an adult secure service (low secure, locked rehabilitation and high relational support housing) were rated over a 20-week period by their multidisciplinary teams. Findings: The GRF showed promising construct validity and appropriate stability and sensitivity to change across time. It enabled measurement and understanding of individual change over time. Staff feedback suggested the GRF is a useable and practical outcome measuring tool. Conclusions: The GRF shows promise for use as a routine outcome monitoring tool within forensic mental health services. 相似文献

We investigated agency directors' perspectives about how service goals should be prioritized for domestic violence and sexual assault service subtypes, including crisis, legal advocacy, medical advocacy, counseling, support group, and shelter services. A sample of 97 (94% response rate) North Carolina domestic violence and/or sexual assault agency directors completed a survey asking participants to rank the importance of service goals. Overall, participants considered emotional support provision to be a critical service goal priority across all service types. Social support and self-care service strategies were deemed less important. However, prioritization of other service goals varied depending on the service type. Statistically significant differences on service goal prioritization based on key agency characteristics were also examined, and agency characteristics were found to relate to differences in service goal prioritization. 相似文献

In the era of traditional media, courts typically relied upon geographic constraints, including where a plaintiff lived or worked, to determine the appropriate community in defamation cases. The rise of the Internet has dramatically changed society – easily and immediately linking users across geography while allowing the rapid spread of information through a variety of channels that pose a challenge to the traditional media model centered around editorial judgment and professional ethics. Thanks in part to its global reach, the Internet has allowed users to engage in both business and social relationships around the world. Because of this, a person's need for a good reputation can no longer be confined solely to location. As a result, this article argues that courts must begin to evaluate other factors when determining relevant community in online defamation cases, positing that courts should utilize factors associated with psychological sense of community theory. 相似文献

Abstract This study examines the effect of victim age, victim attractiveness, the victim's abuse history and respondent gender have on attributions of blame and credibility towards a female victim in a hypothetical child sexual abuse case. A total of 397 respondents from a community sample read a hypothetical child sexual abuse (CSA) scenario in which victim age, victim attractiveness and the victim's abuse history were manipulated. Respondents then completed a 16-item blame attribution questionnaire. Several predictions were made. First, a 10-year-old victim would be deemed less blameworthy and more credible than a 15-year-old victim. Secondly, an attractive victim would be viewed more positively, and attributed less blame, than an unattractive victim. Thirdly, a victim with previous history of being sexual abused—either by the same or different perpetrators—would be deemed more culpable for their own CSA than a first time victims. Finally, female respondents were expected to take a more pro-victim and anti-perpetrator stance than males. Whilst comparatively few differences were found across victim attractiveness and abuse history. Overall findings were broadly in line with predictions. It was concluded that victim age and respondent gender play particularly important roles in the attribution of blame towards victims and perpetrators of child sexual abuse. 相似文献

The study of battered women of color marginalized by their race, gender, sexuality, ethnicity, class, and immigrant status
(defined as an intersectional approach) has created new ways of thinking of and dealing with domestic violence in immigrant
communities. This article applies the principles of an intersectional and interlocking analysis to the experiences of battered
immigrant women in the U.S. In addition, here I bring together another dimension of intersectionality: one that inter-relates
certain dynamics of domestic violence specific to immigrant communities and some of the unique ways in which immigrant communities
are dealing with domestic violence in the U.S. In these ways, we are better able to see both the concerns about displacement
and marginalization, as well as contestation and empowerment of battered immigrant women.
