The primary objective of this paper is to report on the successful implementation of forensic facial approximation in a real case in the forensic context. A three‐dimensional (3D) facial approximation protocol of the skull was performed with free software, applying techniques in a virtual environment that have already been consolidated in the literature. The skull was scanned with the photogrammetry technique, the digital replica was imported in the Blender software (Blender Foundation, Amsterdam) and individualized model sketches of the face were traced with the MakeHuman software (MakeHuman Org) according to the anthropological profile of the victim. The face created was imported in Blender, where it was adapted, modeled, and sculpted on the 3D skull and its soft tissue markers, using an American open‐source application of the technique in the digital environment. The face created in a virtual environment was recognized and legal identification procedures were started, resulting in the more agile delivery of the disappeared body to its next of kin. It is therefore concluded that facial approximation may not be a primary method of human identification, but it can be satisfactorily applied in the forensic field as an individual recognition resource. It has great value in narrowing the search, reducing the number of alleged victims, and leading to identification tests, therefore significantly reducing the number of genetic DNA (deoxyribonucleic acid) tests—which are considered costly for the State or Federation—and consequently reducing the waiting time before delivery of the body to its family.  相似文献

Misdiagnosed PAS confirmed at medicolegal autopsy Pulmonary artery sarcoma (PAS) is a rare disease and usually indistinguishable from acute or chronic thromboembolic disease of the pulmonary arteries. We present a case of pulmonary artery sarcoma in a 54‐year‐old male, who was clinically misdiagnosed as pulmonary thromboembolism. The patient died of disease; however, the actual diagnosis of PAS was made after a medicolegal autopsy. PAS can be a diagnostic challenge for both clinicians and pathologists. In an autopsy case with a clinical suspicion of pulmonary thromboembolism, if there is an abnormal gross appearance in the pulmonary artery, the forensic pathologist should have a high index of suspicion of PAS, which should be ruled out by a histopathologic examination.  相似文献

Insulin glargine is a long-acting insulin analog that is converted after enzymatic cleavage of the arginine pair of the β-chain into its main metabolite M1 (21A-Gly-insulin), which is responsible for the hypoglycemic activity. In all the overdose cases described in the literature, only M1 concentrations have been reported, whereas insulin glargine was always absent or below the limit of quantitation. In this study, we present a case of suicide of a young nurse by injection of insulin glargine in which the parent molecule was found at a toxic concentration in blood. The determination and the discrimination of insulin glargine from human insulin and other synthetic analogs in the blood specimen were performed by liquid chromatography coupled to high-resolution mass spectrometry (Waters XEVO G2-XS QToF) and extraction after precipitation in the presence of bovine insulin (internal standard), with a mixture of acetonitrile/methanol +1% formic acid followed by purification on solid phase extraction cartridges C18. Glargine insulin tested highly positive in the blood with a concentration of 1.06 mg/L. Due to the difficulty in obtaining a M1 pure standard, the metabolite could not be dosed. This unique presence of the parent molecule, reported for the first time, can be explained by inter-individual variability in the rate of conversion to metabolite. Intravenous injection versus subcutaneous injection can also explain the presence of insulin glargine. Finally, the dose injected may have been so high that saturation of the proteolytic enzymes responsible for conversion to M1 should have occurred.  相似文献

“Bullet wipe” is the material deposited by a bullet on any surface with which it comes into contact after it is fired and may contain debris from the gun barrel, including particles of primer and metal fragments from previously fired bullets. X‐ray analysis is a non‐destructive method by which traces of metallic elements can be visually detected. The analysis of osseous defects for radiodense bullet wipe (RBW) assists in determining the presence or absence of perforating gunshot wounds, especially in fragmented, skeletonized remains. The aim of our current study was to determine the frequency of RBW around entrance firearms injuries that perforated bone. We prospectively analyzed entrance gunshot wounds for RBW over a three‐year period using digital X‐ray analysis (n = 59). We retrospectively reviewed the corresponding autopsy reports to determine the frequency of RBW by biologic sex, reported ancestry, age‐at‐death, location of wound, manner of death, range of fire, bullet caliber, and presence of bullet jacket. Data were analyzed by Fisher's exact test or Chi‐square test with significance levels accepted at p < 0.05. RBW was present in 66% (n = 39) of examined cases. Decedent characteristics did not significantly alter RBW distribution, including biologic sex (p = 0.75), reported ancestry (p = 0.49), and age‐at‐death (p = 0.43). Additionally, the location of the osseous entrance gunshot wound, manner of death, range of fire, and cartridge caliber did not affect RBW detection. All cases involving non‐jacketed rounds (n = 5) showed RBW (p = 0.30). To our knowledge, this study is the first to report the frequency of RBW detection from osseous entrance gunshot wounds.  相似文献

ABSTRACT

Many bystander programs to prevent violence have been developed and evaluated in college populations. An exception is the randomized controlled trial of Green Dot, found effective in reducing violence rates and violence acceptance in 26 high-schools (2010–2014). In ‘Life’s Snapshot’, 10,727 seniors were recruited from these same schools with the goal of determining the longer-term efficacy of bystander training. Students in intervention schools could have up to three years of Green Dot exposure. Seniors from intervention versus control schools had significantly lower scores (p <.01) indicating less violence acceptance or sexism for two of five measures. Seniors’ self-reports of bystander training received confirmed these findings. These cross-sectional analyses suggest that some reductions in violence acceptance associated with bystander programming may be maintained into early adulthood.  相似文献

The desired outcome for children in foster care is to be reunited with their parents or to be permanently placed in a stable home. Federal and state legislation directs increased efforts by the social welfare and judicial systems in the United States to act in the best interests of the child and to identify and reduce barriers to permanency. Records from two county dependency courts in Florida were examined and caregivers surveyed to identify issues that prevented them from adopting the child in their care, and to identify services that would have enhanced the likelihood of adoption. The findings and their implications suggest that more integration of the two systems and support for concrete assistance to caregivers are paramount to facilitating adoption of children in foster care.  相似文献

This study examined relationships between perceived heterosexism in high school policies and programs, social environments, and victimization rates among lesbian, gay, bisexual and questioning (LGBQ) students. Secondary analyses of Internet survey data from a large cohort of LGBQ students (N = 2037; 76% male, 82% White; mean age = 16.07; 56% gay or lesbian; 28% bisexual; 16% questioning) yielded moderate correlations between perceptions of non-discrimination and harassment policies, inclusive programs, and the prevalence and tolerance of anti-LGBQ harassment. The perceived availability of inclusive programs was more closely associated with perceptions of the prevalence and tolerance of harassment in schools than were perceived policies. Victimization was related to perceived policies, programs, and harassment. Perceived harassment partially mediated effects of programs on victimization, but perceived programs also predicted victimization even after controlling for perceived harassment. Moderating effects of demographic characteristics (e.g., gender, race, sexual orientation, and outness) were explored.  相似文献

Numerous organizations advocate the need to ‘bridge research and policy’. Philanthropic foundations, national social science funding regimes and international organizations have sought to improve knowledge utilization. Similarly, research consumers such as NGOs and government departments complain of research irrelevance for policy purposes. The concern of this article is with ‘evidence informed policy’ within the field of international development in which the Overseas Development Institute (ODI), a London‐based think tank, forms the case study. Most think tanks are driven by the need to influence immediate political agendas but ODI has also developed organizational strategies of policy entrepreneurship that extend to longer term influence through creating human capital, building networks and engaging policy communities.

The Clothesline Project uses t-shirt art to address the issue of violence against women. Others have argued that the Clothesline Project empowers women in general and female victims of violence in particular. In this article we attempt to deepen this argument, first, by tying it to the existing "faces of power" literature. Using this literature, we argue that the Clothesline Project empowers by creating a public space for political action, offering an alternative communicative medium, educating in a context of dismissal and silence, and contributing to social and cultural transformation. Second, we develop the notion of affective power and argue that it amplifies the practical power of the Clothesline Project.  相似文献
