Proton-induced X-ray emission (PIXE) is a spectroscopic technique that provides the researcher with the elemental composition of a given target material. In this paper, we illustrate the utility of PIXE analysis in two forensic contexts: (1) case of cremation in which the nature of the remains is questioned and (2) cases of death by gunshot wound. In the first case, elemental analysis by PIXE reveals that the purported cremated remains are not bone. The last two cases show that radiopaque metallic residue embedded in bone is composed of lead from a projectile. 相似文献

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

The Federal Housing Administration (FHA) deserves considerable credit for helping support the housing market during the recent financial crisis by increasing its own market share. However, as the recovery continues, the FHA can gradually return to its “traditional” role as an insurer of low-down-payment home mortgages for low-to-moderate-income and first-time homebuyers. A major concern going forward is susceptibility to increased adverse selection if it continues in nontraditional markets. Indeed, the modest market share of the FHA going into the housing collapse was important both in limiting its losses and in allowing it to maintain the market when other traditional secondary market makers failed. 相似文献

Slimming cactus (Hoodia), found only in southwestern Africa, is a well‐known herbal product for losing weight. Consequently, Hoodia extracts are sought‐after worldwide despite a CITES Appendix II status. The failure to eradicate illegal trade is due to problems with detecting and identifying Hoodia using morphological and chemical characters. Our aim was to evaluate the potential of molecular identification of Hoodia based on DNA barcoding. Screening of nrITS1 and psbA‐trnH DNA sequences from 26 accessions of Ceropegieae resulted in successful identification, while conventional chemical profiling using DLI‐MS led to inaccurate detection and identification of Hoodia. The presence of Hoodia in herbal products was also successfully established using DNA sequences. A validation procedure of our DNA barcoding protocol demonstrated its robustness to changes in PCR conditions. We conclude that DNA barcoding is an effective tool for Hoodia detection and identification which can contribute to preventing illegal trade. 相似文献

This article examined the differential role of self-rumination and self-reflection on the psychological influence of procedural fairness. Study 1 induced self-rumination and self-reflection relative to an outward-focused control. Self-rumination increased the perceived importance of procedural fairness, whereas self-reflection decreased it. Study 2, assessing individual differences in self-rumination and self-reflection, showed that a standard procedural fairness manipulation (voice vs. no voice) predicted future interaction preferences with the enactment source among those high (but not low) in self-rumination and among those low (but not high) in self-reflection. The findings validate a multiple process approach to understanding the role of the self in procedural fairness. 相似文献

ABSTRACTPresent evidence regarding widely used risk assessment tools suggests that such tools may have inferior predictive validity for offenders with a migration background (MB), especially from Turkey and Arab countries. Based on a thorough literature review, we investigated additional risk and protective factors via a postdictive correlational study design. We assumed that delinquency is induced by discrimination, a conflict of values, norms of honour, a disapproval of sexual self-determination, and antisemitism. In contrast, we expected social support to diminish the risk of criminal behaviour. The sampling took place inside and outside prison, where adult men with an Arab or Turkish MB (n?=?140) filled out a questionnaire. Individual norms of honour (r?=?.27?.41), antisemitism (r?=?.31?.37), and a disapproval of sexual self-determination (r?=?.23?.26) were positively correlated with delinquency. The best predictor was the individual’s perception of friends’ norms of honour (r?=?.34?.56). However, only a few significant correlations were found for a perception of individual discrimination (r?=?.08?.14) and an internal conflict of values (r?=?.11?.15), whereas global discrimination (r?=?.20?.29) clearly emerged as a risk factor for delinquency. Social support by nondelinquent peers could be confirmed as having a protective influence against delinquency (r=?.25?.27). Theoretical and practical implications for risk assessment are discussed. 相似文献

Abstract Defendants often feign (i.e. simulate) dissociative amnesia for their crimes. The Symptom Validity Test (SVT) may be used to detect such feigning. Some studies have shown that feigning amnesia for a mock crime has memory-undermining effects. In this study, we wanted to replicate the memory-undermining effects of simulated amnesia. We also examined whether such effects would occur when participants’ memories were evaluated with a SVT. Thirty participants committed a mock crime and then simulated amnesia for it. During a follow-up test, participants were instructed to perform as well as they could on a free recall test and a SVT. Their memory performance was compared with that of a control group (n=30). Although only a minority of simulating participants (7%) was detected by our SVT, the memory-undermining effect of simulating amnesia appeared to be a robust phenomenon. That is, ex-simulators displayed poorer free recall, more commission errors, and lower SVT scores relative to memory performance of honestly responding controls. However, at follow-up testing the poor memory of ex-simulators did not take the form of a real amnesia (i.e. random performance on SVT). 相似文献
