Abstract: Injuries to the upper cervical spine (UCS) are common in traumatic deaths and postmortem computed tomography (PMCT) may contribute to the forensic investigation. This study presents PMCT in comparison with autopsy in the examination of UCS injury. Thirteen consecutive cases with UCS fracture and/or cranio‐cervical dislocation were examined with PMCT and autopsy, and the findings were correlated. Neither of the techniques identified all UCS injuries. Fractures of atlas and axis were best visualized with PMCT whereas cranio‐cervical dislocation was better identified during autopsy. Serious injuries were present after both high‐ and low‐energy trauma. Medico‐legal autopsy in combination with PMCT produced a thorough evaluation of UCS injuries. By combining these procedures detailed investigations, including accident reconstruction and injury pattern analysis, can be performed. This study supports the routine application of PMCT, as a supplement to the medico‐legal autopsy of deaths with UCS injuries.  相似文献

Abstract: An online forensic dental identification exercise was conducted involving 24 antemortem–postmortem (AM–PM) dental radiograph pairs from actual forensic identification cases. Images had been digitally cropped to remove coronal tooth structure and dental restorations. Volunteer forensic odontologists were passively recruited to compare the AM–PM dental radiographs online and conclude identification status using the guidelines for identification from the American Board of Forensic Odontology. The mean accuracy rate for identification was 86.0% (standard deviation 9.2%). The same radiograph pairs were compared using a digital imaging software algorithm, which generated a normalized coefficient of similarity for each pair. Twenty of the radiograph pairs generated a mean accuracy of 85.0%. Four of the pairs could not be used to generate a coefficient of similarity. Receiver operator curve and area under the curve statistical analysis confirmed good discrimination abilities of both methods (online exercise = 0.978; UT‐ID index = 0.923) and Spearman’s rank correlation coefficient analysis (0.683) indicated good correlation between the results of both methods. Computer‐aided dental identification allows for an objective comparison of AM–PM radiographs and can be a useful tool to support a forensic dental identification conclusion.  相似文献

Although traditional intensive supervision programs that have aimed at increasing control and surveillance in the community have not been shown to reduce recidivism, prior research indicates that intensive supervision programs that are based on a human service philosophy and provide treatment to offenders offer more promise. The current research examined the effectiveness of fifty-eight intensive supervision programs and sought to determine whether program philosophy and treatment integrity are associated with reductions in recidivism. The results indicated that both program philosophy and treatment integrity vary independently of one another and are related to the ability of programs to produce meaningful effects on recidivism.  相似文献

Despite a steady decline in sex crime over the past twenty years, new laws, such as residence restrictions, targeting such crime have proliferated. Some scholars have argued that public concern about sexual offending against young children has served as a catalyst for the emergence of these laws. Few studies, however, have empirically tested this claim. To address this gap and to contribute to scholarship on public opinion about crime and justice, this research tests a central implication flowing from prior work—namely, the notion that people with children will be more likely to endorse increased restrictions on where sex offenders can live. Analyses of public opinion data from a 2006 poll of Florida residents suggest that parents are indeed significantly more likely to support such restrictions. Implications of the study for research and policy are discussed.  相似文献

Archaeological remains can provide concrete cases, making it possible to develop, refine or validate medico-legal techniques.In the case of the so-called ‘Joan of Arc's relics’ (a group of bone and archaeological remains known as the ‘Bottle of Chinon’), 14 specialists analysed the samples such as a cadaver X of carbonised aspect: forensic anthropologist, medical examiners, pathologists, geneticists, radiologist, biochemists, palynologists, zoologist and archaeologist. Materials, methods and results of this study are presented here.This study aims to offer an exploitable methodology for the modern medico-legal cases of small quantities of human bones of carbonised aspect.  相似文献

A fatal case of multidrug poisoning by tramadol and nicotine is reported. Tramadol is a centrally acting analgesic used in the treatment of moderate to severe acute or chronic pain. Nicotine, a lipid-soluble alkaloid, is one of the most readily available drugs in modern society. A 46-year-old man was found dead in his bed, and a suicide note was discovered near the body. He had 25 transdermal nicotine patches attached to his thorax and abdomen. Two half emptied bottles were found on the bedside table; the toxicological examination revealed that they contained tobacco and nicotine as well as other drugs such as diphenhydramine. At autopsy, areas of fresh and old myocardial infarction as well as diffuse pulmonary congestion and edema were present. The tramadol concentration was 6.6 μg/mL in femoral venous blood, while levels of nicotine and its primary metabolite cotinine were determined to be 0.6 and 2.0 μg/mL in femoral venous blood. Based on these results, we determined the cause of death to be cardiorespiratory failure induced by the additive effects of tramadol and nicotine shortly after consumption.  相似文献

This study examined whether female-to-male (FTM) psychological aggression predicted men’s relapse of substance use disorder (SUD) 6 months following substance use treatment. Men diagnosed with either a substance abuse or dependence disorder who had recently begun an SUD treatment program participated in the study with their female relationship partners (N = 173). Logistic regression was used to examine the relationship between baseline FTM psychological aggression and SUD relapse when controlling for baseline demographic, dyadic, substance abuse- and treatment-related variables, as well as frequencies of other male- and female-perpetrated aggressive dyadic behaviors. Higher frequencies of severe, but not minor, forms of FTM psychological aggression uniquely predicted an increased risk of relapse at 6 months follow-up. These data add to the developing research program highlighting the negative sequelae of female-perpetrated psychological aggression and also provide an empirical basis for targeting specific dyadic behaviors in the context of SUD treatment and relapse prevention.  相似文献

Translation of evidence-based practice (EBP) into health care policy is of growing importance, with discussions most often focused on how to fund and otherwise promote EBP through policy (i.e., at system level, beyond the bedside). Less attention has been focused on how to ensure that such policies - as enacted and implemented, and as distinguished from the practices underlying policies - do not themselves cause harm, or at least frustrate accomplishment of "therapeutic" goals of EBP. On a different front, principles of therapeutic jurisprudence (TJ) in law have been developed, most prominently in certain areas of law (e.g., mental health and family law), to support more collaborative, less traumatic advocacy and conflict resolution. This paper draws on current applications of TJ and translates such into a therapeutic approach to health care policymaking that moves beyond promotion of EBP in policy. Health care policy itself may be viewed as an intervention that impacts health, positively or not. The goal is to offer a framework for health care policymaking grounded in TJ principles that does not focus on which evidence is "right" for policy use, but rather how we can better understand how consequences of policy, intended or not, affect the well-being of populations. Such framework thus moves policymaking from an either/or debate to a data- and human-driven process. Utilizing TJ framing questions, policies can be developed and evaluated through open dialogue among diverse voices at the table, including - like interventions - the "patients" or, here, targets of such policies. Collectively, they clarify how ends sought - to enhance (or at least not impair) health - can best be achieved through policy when needed, recognizing that as an intervention, there are limits to and boundaries on the usefulness of policy.  相似文献

Two laboratory studies with 332 student participants investigated secondary confessions (provided by an informant instead of the suspect). Participants allegedly caused or witnessed a simulated computer crash, then were asked to give primary or secondary confessions during interrogation. Study 1 replicated the false evidence effect for primary confessions. Secondary confessions were obtained at a high rate, which was increased by false evidence in combination with incentive to confess. In Study 2 a confederate either confessed to or denied crashing the computer. Incentive increased the rate of secondary confession only in the presence of a denial; that is, incentive increased the number of false secondary confessions only. Implications for the use of incentives during informant interrogation are discussed.  相似文献

The purpose of the study was to estimate associations between citizenship status and arrest for crimes among male arrestees. The primary hypothesis was that citizenship status (a rough proxy for immigration) has significant effects on arrest for violent personal crimes, property crimes, and four other selected offenses. Data were derived from the Arrestee Drug Abuse Monitoring (ADAM) Program for the years 2000 through 2002 inclusive. Our sample comprised male arrestees only. Logistic regression models were fitted to the data to estimate the citizenship status-crime relationship. Results showed no significant association between citizenship status and arrest for violent crimes. Non-citizens were 15% less likely than citizens to be arrested for property crimes; they were also less likely to be arrested for weapons offenses and drug offenses. Non-citizens were much less likely to test positive on NIDA-5 drugs than citizens. Non-citizens were, however, 50% more likely than citizens to be arrested for forgery/counterfeiting. It was concluded that public perceptions about the relationship of citizenship status to criminal behavior may be exaggerated and may not be borne out by empirical evidence. Limitations of the study are pointed out, including the fact that in the ADAM data, naturalized immigrants are lumped together with native born citizens.  相似文献
