Even though one of the first bite mark cases was Doyle v. State in 1954 (a bitten cheese case), the research has focused on bite marks inflicted in human skin. As published Papers, Case Reports, or Technical Notes can constitute precedents which are relied upon in making the legal arguments and a considerable amount of case law exists in this area, we present a systematic review on bite mark analysis in foodstuffs and inanimate objects and their underlying proofs for validity and judicial acceptance according to Daubert rulings. Results showed that there is vulnerability in these procedures, and it is essential to demand for focus scrutiny on the known error rates when such evidence is presented in trials. These kinds of bite marks are well documented; however, there has been little research in this field knowing that the protocols of analysis and comparison are the responsibility of the forensic odontologists.  相似文献

Previous research by the authors on an animal model showed that bloodstains can contain additional information about their somatic origin in the form of wound cells. Bloodstains produced by a gunshot wound to the head were distinguished from bloodstains produced by a gunshot wound to the chest by testing the stains for a brain microRNA marker. In this study, the effectiveness of the technique was examined on blood drops shed externally from a stab wound to the liver of rat carcasses. Specifically, investigations were conducted on the liver microRNA marker, rno‐mir‐122‐3p, with the QIAGEN miScript System, and PCR analysis. Between the two stabbing methods used, 67% of the scalpel blades and 57% of the blood drops tested positive for rno‐mir‐122‐3p; however, other samples tested negative giving inconclusive results as to the wound‐of‐origin. The amount of the liver cells in the bloodstains appeared to be related to the extent of trauma.  相似文献

Objectives

This study evaluates the effects of precaution technologies (i.e., window bars, extra locks, alarms and electric fences, CCTV, private security, dogs and combinations of these tools) on household burglary and robbery in Brazil.

Methods

Using a sample of 121,042 unique households from the Brazilian National Household Sample Survey for 2009, this study estimates a Recursive Bivariate Probit to obtain the average treatment effect of these precaution technologies in the likelihood of home burglary and robbery victimization.

Results

This study demonstrates that technology does not reduce home burglaries, but certain combinations of technologies may reduce home robberies. The combination of electric fences and alarms with private security reduces the likelihood of home robbery by 9.5 %, and when combined with a dog, these technologies reduce the likelihood of home robbery by 86 %.

Conclusions

No precaution technology is able to prevent crimes when employed independently. Occupancy combined with a set of technologies can reduce the expected victimization in crimes against property.

Forensic entomotoxicology investigates the effects of chemical substances in the development of scavenger insects and the reflection on estimating the minimum postmortem interval (PMI). To evaluate the impact of the chemotherapeutic drugs cyclophosphamide (CF) and methotrexate (MTX) on the postembryonic development of Chrysomya megacephala, controlled experiments were performed by rearing the larvae on spiked minced beef with different concentrations of these drugs. The results indicated that CF significantly decreased their developmental rate up to 28 h but had no significant effect on larval and adult sizes, survival rate, and sex ratio, whereas MTX decreased larval and adult sizes, survival rate, and there was a deviation in the expected sex ratio toward females in MTX‐exposed larvae but had no significant impact on developmental rate. These negative interference factors should be considered in cases of suspected death of people that have undergone chemotherapy.  相似文献

We have analysed the information in 342 police reports of stranger sexual offences recorded in 2010. We have carried out a multiple correspondence analysis and a cluster analysis using modus operandi variables to identify differential profiles in these types of sexual offences. We have come up with three profiles of stranger sexual offences, which concur in the two techniques used. By analysing the personal variables of the offenders with such profiles, we have found differences in terms of the offender’s country of origin and age. We will discuss the consequences of these results on the police investigation of stranger sexual offences.  相似文献

The aim of this study is to develop a scale to predict intimate partner femicide and severe violence. The sample consists of 1,081 batterer men who were reported to the police station. First, the most significant differences between the severe violence group (n = 269) and the less severe violence group (n = 812) in sociodemographic variables are determined. Both aggressors and victims of the severe violence group have a higher rate of immigration. Second, the proposed 20-item scale is derived from a larger 58-item scale, where only the most discriminative items between severe and nonsevere intimate partner violence are taken into account. Psychometric properties of reliability and validity are rather good. Cutoff scores have been proposed according to sensitivity and specificity. This easy-to-use tool appears to be suitable to the requirements of criminal justice professionals and is intended for use in safety planning. Implications of these results for further research are discussed.  相似文献

With more information the Dutch public becomes less punitive. However, recent studies showed a remaining punitiveness gap between the general public and judges, despite the provision of detailed case information. Moreover, it has been demonstrated that the Dutch public overestimates the courts’ punitiveness. This is not in line with studies abroad. These contradictions raise questions, on the one hand, about the possibility of actual cross jurisdictional differences, on the other hand, about methodological explanations. A limited set of survey questions from studies abroad was therefore replicated with a new Dutch public sample. It focused on questions and methodologies that produced findings most directly at odds with earlier studies in the Netherlands. Using the same measurement approach, findings abroad were reproduced with the new Dutch sample for perceptions of punitiveness of judges and the courts. Thus using a different methodology new findings support conclusions that are opposite to our earlier conclusions. On the other hand, also with methodologies that have produced opposite conclusions abroad, the Dutch public does remain more punitive than judges. In the discussion it is argued that some of the remaining contradictions may be perfectly reconcilable, as long as conclusions are stated in a qualified manner.  相似文献

This essay reconsiders Marx’ prehistory of capital through the lens of the work of Giorgio Agamben, who in the wake of Foucault has proposed a bio-political theory of sovereignty that breaks down the analytical separation between sovereignty and governmentality that Foucault in his work tries to maintain. Although Agamben mentions Marx only once in his study of sovereign power, I argue that his study nevertheless contributes to our understanding of the capitalist relation as not only a governmental but also a sovereign power relation. In the first part of this essay, I show through a philological commentary on Marx’ use of the adjective ‘vogelfrei’—translated as free, rightless, without protection, outlawed—to characterise the proletariat, that the Marxian proletariat is a figure of what Agamben in his study of sovereign power calls bare life. In the second part of the essay, I show that this sovereign dimension of the capitalist relation is also substantiated by Marx’ analysis of the logic of the capitalist relation as that of the exception. After Carl Schmitt, who wrote that ‘sovereign is who decides on the state of exception’, Agamben has argued that the logic of the exception is the logic of sovereign power. Reconsidered through the lens of Agamben’s argument, Marx’ account of the prehistory of capital reveals that there is a sovereign logic of the exception at work in the capitalist relation. In the final part of the essay, I start from Agamben’s single reference to Marx in his study of sovereign power to discuss the importance of my conclusions for Agamben’s political message.  相似文献

The use of seclusion in psychiatric practice is a contentious issue in the Netherlands as well as other countries in and outside Europe. The aim of this study is to describe Dutch seclusion data and compare these with data on other countries, derived from the literature. An extensive search revealed only 11 articles containing seclusion rates of regions or whole countries either in Europe, Australia or the United States. Dutch seclusion rates were calculated from a governmental database and from a database covering twelve General Psychiatric Hospitals in the Netherlands. According to the hospitals database, on average one in four hospitalized patients experienced a seclusion episode. The mean duration according to the governmental database is a staggering 16 days. Both numbers seem much higher than comparable numbers in other countries. However, different definitions, inconsistent methods of registration, different methods of data collection and an inconsistent expression of the seclusion use in rates limit comparisons of the rates found in the reviewed studies with the data gathered in the current study. Suggestions are made to improve data collection, to enable better comparisons.  相似文献

This study investigates whether mothers who are neglectful and at high risk for child physical abuse present a deficit in empathy. Participants were neglectful mothers (n=37), mothers at high risk for child physical abuse (n=22), and nonmaltreating mothers (n=37). The Interpersonal Reactivity Index, a self-report measure assessing specific dimensions of empathy, was used to assess dispositional empathy. No differences between neglectful and non-neglectful mothers were found for perspective taking, empathic concern, and personal distress. High-risk mothers reported less perspective taking and more personal distress than nonmaltreating mothers. No difference between groups was found for empathic concern. The present study supported the hypothesis that parents at high risk for child physical abuse show a deficit in particular aspects of dispositional empathy: personal distress and perspective taking. However, no differences were found between neglectful and nonmaltreating mothers in any dimension of dispositional empathy.  相似文献
