Deaths due to decapitation, especially related to traffic accidents, are rarely found in forensic practice. The present case involves a man and a woman who died from decapitation due to an unusual mechanism while they were riding on a motorbike down a mountain road. The autopsy, which was completed as a physics study, allowed the accident to be reconstructed as follows: A plastic cable that had detached from a timber‐transporting machine whipped the road and hit the two motorcyclists. The impact resulted in the complete severing of both riders’ heads. Involving different scientists in this accident investigation was crucial to understanding the dynamics of the accident. In fact, in addition to scene inspection and autopsy, a physics study was carried out on the cable and the clamp involved, which led to an explanation for the abrupt movement of the cable and, thus, to a thorough reconstruction of the accident.  相似文献

Forensic entomology is a branch of forensic science in which insects are used as evidence in legal investigations relating to humans, domestic animals and wildlife. One of the theoretical pillars on which the discipline is based concerns the fact that flies colonize a body after death. However in cases of myiasis, maggots are present before death, with consequences in the correct estimation of the minimum postmortem interval (mPMI). We report here the case of a woman, largely colonized by fly larvae, who has lain alive in her garden for four days prior to being rescued. Larvae were found on the conjunctivae, the bronchi, the rectum and vagina. The woman's death, two months later, was caused by tetanus. The consequences of myiasis on mPMI estimation are here discussed. In fact, despite she was still alive larvae, indicated and estimated age of 1.5–2.5 days, based on environmental and body temperature.  相似文献

This paper presents a product development methodology for use with indigenous rural workers. It is based on the revival of cultural and social values, with a focus on the conservation of natural resources. Illustrated by the case of Mixtec craftswomen in Mexico, this paper shows how poor groups can improve their living conditions through innovation and the diversification of their products. The process combines techniques of product development based on marketing, with a participatory focus and continuous improvement, in order to develop a unique and high‐quality product that can be more successfully marketed. The craftswomen are now able to plan their production and can evaluate and commercialise their products.  相似文献

Haplotype data were obtained from a sample of 777 unrelated male individuals from Antioquia Department (Colombia), for eight Y-chromosome STRs (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392 and DYS393). A total of 442 different haplotypes were identified of which 334 were represented only once in the database and the most frequent haplotype was found in 32 individuals. A high haplotype diversity was found (99.45%). Genetic distances were calculated using previously published haplotype data and the lowest values were found for the comparisons with samples of lberian origin.  相似文献

The aims of the study were to assess the psychometric properties of the Spanish version of the Index of Spouse Abuse (ISA), and to validate it against external criteria of intimate partner violence. The Spanish version of the ISA was administered to 223 non-abused women and 182 victims of intimate partner violence. Internal consistency coefficients oscillated between 0.88 and 0.98. The Confirmatory Factor Analysis failed to replicate the original two-factor structure. Using Exploratory Factor Analysis, a two-factor solution was found: physical (ISA-P) and non-physical (ISA-NP), but the items included in each factor were slightly different from the original two subscales. Receiver operating characteristic curve analysis revealed an AUC value for the ISA global score of 0.99 (95% CI: 0.98–0.99), with the optimal cut-off of 12 for detecting intimate partner violence. The Spanish version of the ISA is a valid instrument for detecting intimate partner violence in a female population.  相似文献

Since 1948 the re-designation of depopulated Palestinian villages as national parks has evoked Lippet’s “cartography of nowhere”, as ruins and unmarked sites are subsumed in the process of material forgetting. Juxtaposing narratives and material mnemonics, this article assumes the villages of Deir Yassin, Suba, Kufr Bir’im and Iqrit as case studies to determine the extent to which memory infuses ruins with the ability to counter contemporary narratives. The article subsequently explores the use of debris in the sustenance of national memory, and questions how far “haunting” the land through commemorative tours and in situ story-telling renders the ruins noeuds de mémoire, as opposed to lieux de mémoire. Finally, the transition of the ruins from sites of history to sites of activism is charted through the use of theatre and technology that draw on the past and present as forms of cultural resistance.  相似文献

The biofuel project is an agro-industrial development and politically contested policy process where governments increasingly become global actors. European Union (EU) biofuels policy rests upon arguments about societal benefits of three main kinds - namely, environmental protection (especially greenhouse gas savings), energy security and rural development, especially in the global South. Each argument involves optimistic assumptions about what the putative benefits mean and how they can be fulfilled. After examining those assumptions, we compare them with experiences in three countries - Germany, Brazil and Mozambique - which have various links to each other and to the EU through biofuels. In those case studies, there are fundamental contradictions between EU policy assumptions and practices in the real world, involving frictional encounters among biofuel promoters as well as with people adversely affected. Such contradictions may intensify with the future rise of biofuels and so warrant systematic attention.  相似文献

Despite the salience of behavioral autonomy and independence to parent–child interactions during middle adolescence, little is known about parenting processes pertinent to youth autonomy development for Latino families. Among a diverse sample of 684 Latino-origin parent–adolescent dyads in Houston, Texas, this study examines how parents’ cultural orientations are associated directly and indirectly, through parental beliefs, with parenting practices giving youth behavioral autonomy and independence. Informed by social domain theory, the study’s parenting constructs pertain to youth behaviors in an “ambiguously personal” domain—activities that adolescents believe are up to youth to decide, but which parents might argue require parents’ supervision, knowledge, and/or decision-making. Results for latent profile analyses of parents’ cultural identity across various facets of acculturation indicate considerable cultural heterogeneity among Latino parents. Although 43 % of parents have a Latino cultural orientation, others represent Spanish-speaking/bicultural (21 %), bilingual/bicultural (15 %), English-speaking/bicultural (15 %), or US (6 %) cultural orientations. Structural equation modeling results indicate that bilingual/bicultural, English-speaking/bicultural, and US-oriented parents report less emphasis on the legitimacy of parental authority and younger age expectations for youth to engage in independent behaviors than do Latino-oriented parents. Parental beliefs endorsing youth’s behavioral independence and autonomy, in turn, are associated with less stringent parental rules (parental report), less parental supervision (parental and youth report), and more youth autonomy in decision-making (parental and youth report). Evidence thus supports the idea that the diverse cultural orientations of Latino parents in the US may result in considerable variations in parenting processes pertinent to Latino adolescents’ development.  相似文献

Many young adolescents are dissatisfied with their body due to a discrepancy between their ideal and actual body size, which can lead to weight cycling, eating disorders, depression, and obesity. The current study examined the associations of parental and peer factors with fifth-graders’ body image discrepancy, physical self-worth as a mediator between parental and peer factors and body image discrepancy, and how these associations vary by child’s sex. Body image discrepancy was defined as the difference between young adolescents’ self-perceived body size and the size they believe a person their age should be. Data for this study came from Healthy Passages, which surveyed 5,147 fifth graders (51 % females; 34 % African American, 35 % Latino, 24 % White, and 6 % other) and their primary caregivers from the United States. Path analyses were conducted separately for boys and girls. The findings for boys suggest father nurturance and getting along with peers are related negatively to body image discrepancy; however, for girls, fear of negative evaluation by peers is related positively to body image discrepancy. For both boys and girls, getting along with peers and fear of negative evaluation by peers are related directly to physical self-worth. In addition, mother nurturance is related positively to physical self-worth for girls, and father nurturance is related positively to physical self-worth for boys. In turn, physical self-worth, for both boys and girls, is related negatively to body image discrepancy. The findings highlight the potential of parental and peer factors to reduce fifth graders’ body image discrepancy.  相似文献

There is an increasing demand for herbal medicines in weight loss treatment. Some synthetic chemicals, such as sibutramine (SB), have been detected as adulterants in herbal formulations. In this study, two strategies using near infrared (NIR) spectroscopy have been developed to evaluate potential adulteration of herbal medicines with SB: a qualitative screening approach and a quantitative methodology based on multivariate calibration. Samples were composed by products commercialized as herbal medicines, as well as by laboratory adulterated samples. Spectra were obtained in the range of 14,000–4000 per cm. Using PLS‐DA, a correct classification of 100% was achieved for the external validation set. In the quantitative approach, the root mean squares error of prediction (RMSEP), for both PLS and MLR models, was 0.2%w/w. The results prove the potential of NIR spectroscopy and multivariate calibration in quantifying sibutramine in adulterated herbal medicines samples.  相似文献
