The present study aimed at providing data to assess the secondary transfer of organic gunshot residues (OGSR). Three scenarios were evaluated in controlled conditions, namely displacing a firearm from point A to point B, a simple handshake and an arrest involving handcuffing on the ground. Specimens were collected from the firearm, the hands of the shooter and the non-shooter undergoing the secondary transfer in order to compare the amounts detected.Secondary transfer was observed for the three scenarios, but to a different extent. It was found that displacing a firearm resulted in secondary transfer in <50% of the experiments. The firearm also had an influence, as contrary to the pistol, no secondary OGSR were detected using the revolver. Shaking the hand of the shooter also transferred OGSR to the non-shooter's hand. In that case, the amount of OGSR was generally higher on the shooter than on the non-shooter. Finally, the largest secondary transfer was observed after the arrest with handcuffing with positive results in all cases using the pistol. In that scenario, the amounts on the shooter and the non-shooter were in the same range.This study highlights that the secondary transfer must be taken into account in the interpretation of OGSR. Indeed, an individual's hands might be contaminated by handling a firearm or having physical contact with a shooter. 相似文献

Abolitionism is an important, but often overlooked, theoretical and political alternative to the failings and injustices of the penal system and other forms of social control. While many have documented different approaches to abolitionist strategy, few have explored the work that is done sensitizing individuals to abolitionism, including in university settings. Through an analysis of student journal entries, this study discusses how students enrolled in a mandatory abolition course engaged with the viability of, and barriers to, a world without prisons, punishment and other forms of control. By looking at abolition as a threshold concept, we consider how students negotiate the concept of abolition as a radical justice alternative. As the journal entries showed, while students were able to understand the basic tenets of abolition, many remained in a liminal state between the existing system and the unknown landscape of abolition, and could not see its viability or possibility as a radical alternative. We conclude that other learning strategies may have been helpful in moving student through such a ‘dangerous’ concept. Further research on sensitising individuals to abolition is needed given the current proliferation and intensification of penal and carceral institutions today. 相似文献

Extreme fragmentation can complicate the inventory of human skeletal remains. In such cases, skeletal mass can provide information regarding skeleton completeness and the minimum number of individuals. For that purpose, several references for skeletal mass can be used to establish comparisons and draw inferences regarding those parameters. However, little is known about the feasibility of establishing comparisons between inherently different materials, as is the case of curated reference skeletal collections and human remains recovered from forensic and archaeological settings. The objective of this paper was to investigate the effect of inhumation, weather and heat exposure on the skeletal mass of two different bone types. This was investigated on a sample of 30 human bone fragments (14 trabecular bones and 16 compact bones) that was experimentally buried for two years after being submitted to one of four different heat treatments (left unburned; 500?°C; 900?°C; 1000?°C). Bones were exhumed periodically to assess time-related mass variation. Skeletal mass varied substantially, decreasing and increasing in accordance to the interchanging dry and wet seasons. However, trends were not the same for the two bone types and the four temperature thresholds. The reason for this appears to be related to water absorption and to the differential heat-induced changes in bone microporosity, volume, and composition. Our results suggest that mass comparisons against published references should be performed only after the skeletal remains have been preemptively dried from exogenous water. 相似文献

This study aimed to develop an aquatic decomposition scoring (ADS) method and investigated the predictive value of this method in estimating the postmortem submersion interval (PMSI) of bodies recovered from the North Sea. This method, consisting of an ADS item list and a pictorial reference atlas, showed a high interobserver agreement (Krippendorff's alpha ≥ 0.93) and hence proved to be valid. This scoring method was applied to data, collected from closed cases—cases in which the postmortal submersion interval (PMSI) was known—concerning bodies recovered from the North Sea from 1990 to 2013. Thirty‐eight cases met the inclusion criteria and were scored by quantifying the observed total aquatic decomposition score (TADS). Statistical analysis demonstrated that TADS accurately predicts the PMSI (p < 0.001), confirming that the decomposition process in the North Sea is strongly correlated to time. 相似文献

Nosocomial infections have become a major issue of public health and lead to an increasing number of suits for damages. We present a rare case of Aspergillus contamination during cardiac surgery, describe the medicolegal investigation, and present the new system for compensation of bodily injury after nosocomial infection in France, based on the law of March 4, 2002 on patient rights and quality in the health system. This case demonstrates the limits of compensation for nosocomial infections on the grounds of national solidarity. The expert report requested by the regional commission for conciliation and compensation is of fundamental importance in enabling the commission to decide between fault and inherent risk of treatment. 相似文献

Developing a strategy to characterize the odor prints of individuals should be relevant to support identification obtained using dogs in courts of justice. This article proposes an overview of the techniques used for the forensic profiling of human odor. After reviewing the origin of human odor—both genetic and physiological—the different analytical steps from sample collection to statistical data processing are presented. The first challenge is the collection of odor, whether by direct sampling with polymer patches, cotton gauze, etc., or indirect sampling with devices like Scent Transfer Unit. Then, analytical techniques are presented. Analyses are commonly performed with gas chromatography coupled with mass spectrometry. As they yield large amounts of data, advanced statistical tools are needed to provide efficient and reliable data processing, which is essential to give more probative value to information. 相似文献

A study was conducted to test whether it is possible to build a model to distinguish true and false allegations of rape based on the theory of fabricated rape. The theory is based on the principle that a false complainant of rape has not been raped and has to fabricate a story while the story of a true victim is based on recollections of the event. Consequently, false complainants will behave as liars do, construct their story based on their own sexual experiences and on mental representations, beliefs of how such a crime would happen (De Zutter et al. in Eur J Psychol Appl Leg Context. doi: 10.1016/j.ejpal.2016.02.002, 2016). To test the theory and to build a model to discriminate between true and false allegations of rape, a police sample of true and false allegations was studied. A total of 129, 72 true and 57 false, allegations of rape fulfilled the stringent criteria of the current study, among others on ground truth. Fifty-four allegations of rape, 27 true and 27 false, were used to build a prediction model based on the theory of bounded rationality by Gigerenzer (2002). The remaining 75 cases, 45 true and 30 false, were blindly categorised as either true or false based on the model. The model was able to predict the true nature of the majority of allegations with an accuracy rate of 91 %. Thus, it seems possible to discriminate to a considerable extend between true and false allegations of rape. 相似文献

We employ a rational choice framework to understand the conditions under which sex traffickers allow their victims access to telecommunications devices while under their control. We posit that sex traffickers are rational actors who make calculated decisions regarding whether to allow their victims access to the Internet and cell phones. We hypothesize that sex traffickers allow younger victims and those they did not defraud in the recruitment process greater access to telecommunications devices because these decisions maximize their payoffs with minimal risk. However, we hypothesize that younger victims’ access to telecommunications devices is conditional on whether they have been defrauded in recruitment. In order to test these hypotheses, we deployed a survey to 115 victims of sex trafficking in the United States to learn about how they were recruited by their sex trafficker and the level of access they had to technology while under their sex trafficker's control. We find support for all of our hypotheses. The results have serious implications for criminal justice policy and practice. 相似文献

While prior research has shown that the probability of detection plays a role in the decision-making of many offenders, much less is known on offenders’ relative success in avoiding arrest. In this study, we draw from detailed criminal career data on 172 offenders involved in lucrative criminal activities to examine the role of criminal competence in the probability of being arrested in a given month. We examine a particular aspect of competence, criminal efficiency, which is defined as the ability to earn a relatively large amount of money for each crime committed. Our research design allows us to disentangle the effect of criminal efficiency as a static trait of offenders from the dynamic variations in efficiency that offenders experience over time. Results show that efficiency is a strong, negative predictor of arrest, both at the static and dynamic levels. 相似文献
