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

Fly feces and regurgitation deposits may be mistaken for bloodstain patterns at a crime scene, potentially compromising event reconstruction and/or misdirecting police resources. In some instances, these artifacts contain sufficient human biological material to generate a full DNA profile, sometimes 2 years after deposition. Clearly, it is important that investigators can make the distinction between artifacts and bloodstains. This study examined 6645 artifacts deposited on a smooth, nonporous surface after Lucilia cuprina were fed human blood. Artifacts were also compared with bloodstains on a variety of other surfaces. Both similarities and differences were found between artifacts and bloodstains, highlighting the need for an identification system to assist personnel with little training in bloodstain pattern analysis. The morphology of the artifacts has been described so that these deposits may be more clearly distinguished from bloodstains, targeted by crime scene personnel as potential sources of human DNA, and/or identified as potential evidence contaminants. Flowcharts have been devised to facilitate the analysis. 相似文献

The chemical composition of a fingermark potentially holds a wealth of information about the fingermark donor, which can be extracted by immunolabeling. Immunolabeling can be used to detect specific components in fingermarks; however, to be applicable in the forensic field, it should be compatible with commonly used fingerprint visualization techniques. In this study, the compatibility of immunolabeling with two different fingerprint visualization techniques, magnetic powdering and ninhydrin staining, was investigated on fingermarks deposited on glass and on nitrocellulose membranes. With dermcidin as antigen of interest, immunolabeling was performed successfully on all developed fingermarks. We can conclude that immunolabeling is compatible with magnetic powdering and ninhydrin staining, which can be of great forensic value. 相似文献

Paradoxes of Urban Housing Informality in the Developing World 总被引:1,自引:0,他引:1
Jean‐Louis van Gelder 《Law & society review》2013,47(3):493-522
This article addresses a series of paradoxes regarding informal settlements in cities in the developing world and their relation with the legal system. The first paradox regards the penalization of illegal land occupations on the one hand versus the legalization of that same practice on the other. Second, it looks at the relationship between land occupations as systematic violations of property rights, but with the goal of forming new property rights and thus paradoxically supporting private property as a substantive principle. Third, the reasoning behind the fact that the same system that denies legal access to housing for poor sectors simultaneously attempts to incorporate informal settlements in an ad hoc manner through legalization schemes is examined. It is shown that there is a logic to these paradoxes, which, although contradictory from standard legal perspectives, can be accommodated within a theoretical framework that distinguishes an internal normative order operating within informal settlements, from the state legal system, operative outside it. The proposed framework not only settles the paradoxes, but, this article concludes, can also guide attempts to deal with the enormous anticipated growth of informality in the developing world. 相似文献

In 2009, the Netherlands introduced a 10-day temporary restraining order (TRO) intended for adult perpetrators of domestic violence to defuse dangerous situations and to reduce recidivism by combining a legal action with social services. For this study, 18 victims and 10 perpetrators were interviewed about their experiences with the TRO, related professional help, and the influence the TRO had had on their lives. The interviews were transcribed verbatim and subsequently qualitatively analyzed. Most of the victims were positive about the TRO period. Perpetrators were less positive. The vast majority of respondents accepted help during the TRO and were positive about the professionals’ attitudes, but not necessarily about the type of help. Most respondents reported an increase in their wellbeing, new insights, and no or less serious re-assaults by the perpetrator. The results suggest that, in the short term, TROs have a mainly positive effect on both victims and perpetrators. 相似文献

At the end of the 1990s, a moral panic erupted in the Netherlands about the phenomenon of what came to be known as ‘loverboys’. The suspicion was that a growing number of Dutch girls were being groomed by handsome young men who employed all sorts of devious methods to prepare their girlfriends for life as a prostitute. Stories about a new generation of pimps, often of Moroccan origin, regularly appeared in the Dutch media. In this article, based on ethnographic fieldwork on pimps operating in the red-light district of Amsterdam, we describe the ways in which these young men operate and how they justify their behaviour. On the basis of empirical research we intend to present a more realistic picture of what goes on in the prostitution industry and highlight the discrepancy between what is reported in the media and what is actually happening in the prostitution sector. We also examine the background to the moral panic about loverboys and the ways in which these young men were supposedly able to induce many young girls into becoming prostitutes. 相似文献

This paper addresses the effectiveness of auctions and legal unbundling as regulatory measures to tender a vertically integrated industry more competitive. Specifically, I analyze if implementing auctions and legal unbundling can counter market power in an industry where a Vertically Integrated Corporation (VIC) has a monopoly position in an essential, scarce upstream activity and also owns one of the firms active in the competitive downstream activity. In an earlier paper, Van Koten (2011), I showed that in this configuration the VIC, by having its downstream firm bid more aggressively, can—through increased auction revenue—increase its profit, while disadvantaging downstream competitors and lowering efficiency. Here I analyze the regulatory measure of also legally separating the downstream firm from the VIC. I show that such a measure may only be partially effective; the VIC can formulate a simple compensation scheme that does not violate restrictions typically imposed by legal separation but induces the manager of the VIC-owned downstream firm to bid more aggressively. This increases the profits of the VIC, decreases efficiency, and disadvantages downstream competitors. 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 The purpose of the current study was to examine the effect of clothed and unclothed human figure drawings (HFDs) on children's reports of touch. Eighty 4/5-year-olds and 80 9/10-year-olds participated in a staged event in which measurements of their body parts (e.g. waistline) were taken. Specifically, they were touched on 10 different locations. Immediately or three weeks after the event, they had to report where they had been touched. Half of the children received a clothed HFD while the other half was provided with an unclothed HFD to assist children in their recall. When we compared children's recall before and after the presentation of a HFD, we found that clothed and unclothed HFDs significantly decreased the accuracy of children's reports of touch. So, although children reported more correct touches after the presentation of a HFD, they were also more likely to include more incorrect information in their reports of touch. 相似文献
