Decompositional odor analysis database 总被引:1,自引:0,他引:1

This study, conducted at the University of Tennessee's Anthropological Research Facility (ARF), describes the establishment of the Decompositional Odor Analysis (DOA) Database for the purpose of developing a man-portable, chemical sensor capable of detecting clandestine burial sites of human remains, thereby mimicking canine olfaction. This "living" database currently spans the first year and a half of burial, providing identification, chemical trends and semi-quantitation of chemicals liberated below, above and at the surface of graves 1.5 to 3.5 ft deep (0.45 to 1.0 m) for four individuals. Triple sorbent traps (TSTs) were used to collect air samples in the field and revealed eight major classes of chemicals containing 424 specific volatile compounds associated with burial decomposition. This research is the first step toward identification of an "odor signature" unique to human decomposition with projected ramifications on cadaver dog training procedures and in the development of field portable analytical instruments which can be used to locate human remains buried in shallow graves. 相似文献

The stable isotope ratios of a seized pathogen culture could potentially reveal information about the environment in which the agent was produced. In this paper we describe general relationships between stable isotopes of carbon, nitrogen, and hydrogen in bacteriological culture media and spores of Bacillus subtilis, an endospore-forming soil bacterium. In numerous media that varied both in nutrient composition and water stable isotope ratios, medium to spore enrichment in carbon isotopes was 0.3 +/- 2.0% per thousand (parts per thousand), and in nitrogen, 4.5 +/- 0.7% per thousand. We achieved mass balance for the contribution of hydrogen isotopes from nutrients (70%) and water (30%) to spores in independent experiments by varying the isotope ratios of nutrients or water. A model was derived for predicting the isotope ratio values of spores from those in nutrients and water. 相似文献

Within the past decade, restorative justice has emerged as a truly global phenomenon. Although retributive justice has dominated the penal landscape, more recently, restorative principles at sentencing have attracted increased attention. Restorative sentencing emphasizes the importance of compensation and reconciliation between victims and offenders and pays less attention to establishing proportionality between the seriousness of the offense and the severity of the sentence imposed. Although voluminous (and proliferating), the scholarly literature on restorative justice has to date neglected one critical issue: public opinion with respect to this justice paradigm. Public opinion researchers too, have generally overlooked this topic. The goal of this paper is to determine which elements of the new paradigm generate public approval, and which features are likely to encounter or provoke public opposition, drawing upon related international research published in English over the past 20 years (1982–2002). The review reveals widespread support for restorative sentencing options, such as community service, compensation, and restitution, particularly when applied to young offenders. However, it also seems clear that public support for these alternatives to punitive sentencing options declines as the seriousness of the offence increases, suggesting strong public adherence to the retributive principle of proportionality in sentencing. 相似文献

Literature assessing knowledge of and attitudes toward social issues has demonstrated that mental health professionals and lay persons often differ greatly. To add to the normative information in the field of psychological abuse and to determine whether the differences previously found between mental health professionals and lay persons extend to this field, a sample from each group rated psychologically aggressive items by a husband toward his wife. For the 102 items, psychologists were more likely to label the behaviors as "psychological abuse," but this tendency was due to psychologists considering the behaviors as either "always" or "possibly" abusive, whereas lay persons demonstrated a bimodal response pattern of rating the behaviors as "always" or "never" psychological abuse. Lay persons were much more likely than psychologists to rate items high in terms of severity level, however. The two groups used different contextual factors for determining that a behavior was psychological abuse when they initially were uncertain that it was abusive. 相似文献

A new AIDS-in-the-Workplace program being implemented in Québec emphasizes the rights of workers living with HIV/AIDS. The program tackles issues such as confidentiality of HIV status, access to insurance benefits, discrimination, and the need for employers to take reasonable measures to accommodate the disabilities of workers. 相似文献

Abstract. Perhaps the strongest empirical finding in political science is 'Gamson's Law': the near-perfect relationship that exists in parliamentary systems between a coalition party's seat contribution to the government and its quantitative allocation of cabinet portfolios. Nevertheless, doubts remain. What would happen if the salience or importance of the various portfolios was also taken into account? Should it not be the case that payoffs correspond with bargaining power rather than seat contributions? And perhaps most significantly, would addressing these issues produce evidence that the parties designated to form governments extract disproportionately large payoffs for themselves, as predicted by 'proposer' models of bargaining? Utilizing the results of a new expert survey of portfolio salience in 14 Western European countries, the authors of this article explore each of these questions. Their basic finding is that salience-weighted portfolios payoffs overwhelmingly mirror seat contributions, contra proposer models and any other models based on bargaining power. The article concludes with a discussion of the implications for formal models of bargaining. 相似文献

The properties of amelogenin amplification system and, in particular, of its species specificity, were studied. DNA preparations extracted from cattle (cow/bull), pig, ram and from poultry (hen), as well as from dog and cat, were used as a matrix for polymerase chain reaction (PCR) involving a standard scheme of enzymatic amplification of the amelogenin gene. It was demonstrated that, unlike for the human DNA, the amelogenin test couldn't be used for the DNA of examined animals as a sex-specific marker. However, there is a danger of a false determination of the male sex in the female origin samples during a forensic-experts' typing of the amelogenin gene, if there is an admixture of an animal DNA to a human DNA preparation. As for the biological samples of the animal origin, there is a possibility of a false-female sex determination. It can be attributed to an incorrectly selected standard of the molecular weight or to its remote location on the gel as well as to the use of an inaccurately calculated algorithm designed for determining the sizes of analyzed fragments. 相似文献

The traditional methods of investigations according to systems AB0, Gm and Hp were used to define the serological specificity of home gooses' blood. The experimental examinations' results related with mixed bloodstains of man and home gooses are described. A possibility is demonstrated to identify the blood group factors of man in bloodstains with admixture of home-goose blood. 相似文献

The contents of acetaldehyde (AA) in biological fluids obtained from the dead with the confirmed lethality causes, i.e. ischemic heart disease (IHD), alcoholic cardiomyopathy (ACMP) and mechanical traumas (MT), were examined on an actual forensic-medical material (AFMM). 14 death cases of males, aged 18 to 45, were studied. The method of gas-liquid chromatography (GLC), or rather its variation of vaporphase analysis, was used to state the presence and to assess the concentration of acetaldehyde. The results revealed differences between concentrations of acetaldehyde in the examined groups depending on the presence or absence of alcoholemia. Thus, the AA concentrations were found in trace quantities in the MT group free of alcoholic intoxication; while, when it was present in this group, the concentrations went up several-fold. A higher AA content was typical of the ACMP group in all examined subjects both with and without alcoholic intoxication. The final study results are suggestive of that the AA determination in blood, urine and liquor by GLC could be used, within the forensic medical practice, in assessing a severity degree of alcoholic intoxication while establishing the lethal outcome cause due to chronic pathologies and MT. 相似文献
