A study was conducted to examine the potential of the considerable variability of the lead isotope compositions in bullets (projectiles) and primers in shooting incident investigations. Multiple-collector inductively coupled plasma mass spectrometry (MC-ICP/MS) was used to analyze lead isotopic compositions in projectiles, cartridge cases, firearms discharge residues (FDR) in barrels of firearms and in the gunshot entries. .22 caliber plain lead and plated ammunition and 9 mm Luger full metal jacket (FMJ) ammunition were employed in shooting experiments using semiautomatic pistols. Cotton cloth served as the target material and two firing distances were tested; 1 cm (near contact) and 2 m distances. It was observed that various mechanical or chemical means of cleaning do not completely remove lead deposits ("lead memory") from barrels of firearms. Nonetheless, it was shown that analysis of lead isotopic composition may provide valuable evidence in investigating specific scenarios of shooting incidents. For instance in a shoot-out where several firearms and ammunition brands are involved, it may be feasible to point out which ammunition and/or firearm caused a particular gunshot entry if the ammunition brands involved (bullets and primers) differ considerably in their lead isotopic composition. 相似文献

Terrorists trained on European soil, but originating from the Middle East, attacked the world's only superpower on September 11, 2001. Countering this terrorist threat has become an increasingly significant part of European Foreign Policy. At the same time, the European Neighbourhood Policy (ENP) has become an increasingly important dimension of European Foreign Policy. This article examines the extent to which counterterrorism has occupied a prominent place in the ENP, with a particular focus on the Southern Mediterranean ENP partners. The findings of this article suggest that, despite the commonly held view in the literature that security issues, in particular terrorism, have dominated the ENP agenda, counterterrorism cooperation between the European Union (EU) and its Southern Mediterranean ENP partners has not advanced as much as might have been expected. 相似文献

This article addresses the concern that democratization may contribute to the reproduction of neo-patrimonialism, rather than to counteract it. The article reports the result of a survey among members of parliament in Ghana regarding their election campaigns. Total spending, sources of funds, and their usage are analysed in the context of the consolidation of liberal democracy. The survey results are supplemented with data collected in 34 interviews with MPs. The data show that MPs are involved in patron-client relationships to a significant degree to reproduce their political power. Furthermore, the prevalence of patronage politics among MPs in Ghana has increased throughout the period of democratic rule. This persistent pattern of patronage politics threatens the very heart of democratic consolidation. Vertical accountability and legitimacy is threatened by alternative pacts of loyalty, expectations of corruption, and tendencies to delegative mandates. Horizontal accountability risks pervasion by 'big man' interventions, and by insufficient allocation of time to monitoring the government and legislative activities. 相似文献

The distribution of DNA on the filter paper of smoked cigarette butts was quantitatively mapped using real‐time quantitative polymerase chain reaction. The filter papers from smoked cigarette butts collected from indoor and outdoor sources were sliced into equal pieces and the amount of DNA on each slice was determined. This study found that the cigarette butt filter papers sliced parallel to the seam of the cigarette had more uniformly distributed DNA on the slices and in most cases, there was enough DNA on each slice to obtain a complete DNA profile. The perpendicular slices had a less uniform pattern of distribution and some slices did not have enough DNA to obtain an interpretable DNA profile. Cigarette butts found indoors also had more DNA per cigarette on average than cigarette butts found outdoors. 相似文献

Luminol, Bluestar®, and Hemascein® were tested to compare detection sensitivities to latent blood. Untreated, EDTA‐treated human blood, and a catalytically similar blood substitute were diluted (neat to 1:1,000,000) and pipetted onto a variety of substrates. Luminol and Bluestar® performed similarly on all surfaces and fabrics. Hemascein® yielded poor results on wood surfaces, but performed well in the detection of latent blood on fabrics. Results from untreated, EDTA‐treated, and synthetic blood results indicate that EDTA‐treated blood is similar or slightly less sensitive than untreated blood at all dilutions and on all substrates, and the synthetic blood is less sensitive than real blood, but consistent in detection threshold and thus is useful as a training aid. Additionally, some foods and household chemicals that have previously been shown to cross‐react were tested with Bluestar®, Hemascein®, and luminol. Hemascein® cross‐reacted with many substances, while both luminol reagents were more discriminating. 相似文献

Law contains many dualities, though most, if not all, of these dualities resolve into one complex puzzle: To what extent is law a matter of pure social facts, or moral value untethered to social facts? I argue that each concept of law reconciles this duality in a different way on the basis of certain beneficial consequences that might result. Instead of pitting concepts against one another universally, we should accept that the balance between law's social fact and moral value dimensions is context‐specific in relation to particular legal puzzles. This balance can be achieved only by considering both political theory and empirical data. 相似文献

Abstract When eyewitnesses are exposed to misinformation about an event from a co-witness, they often incorporate this misinformation in their recall of the event. The current research aimed to investigate whether this memory conformity phenomenon is due to change in the witness's memory for the event, or to social pressures to conform to the co-witness's account. Participants were shown a crime video and then asked to discuss the video in groups, with some receiving misinformation about the event from their discussion partners. After a one-week delay some participants were warned about possible misinformation before all participants provided their own account of the event. In Study 1, participants made remember/know judgments about the items recalled, and in Study 2 they indicated the source of their memories. Co-witness information was incorporated into participants’ testimonies, and this effect was not reduced by warnings or source monitoring instructions, suggesting memory change may have occurred. However, there was some indication that remember/know judgments may help distinguish between ‘real’ memories and co-witness information. 相似文献

AbstractApproximately half of sexual offenders in prison and community settings refuse to participate in sex offender treatment programmes; however, the reasons for this remain largely unexplored. This pilot study used the previously untested Treatment Refusal Scale—Sexual Offender Version in an English prison, with 72 adult males (63 treatment accepters and nine treatment refusers) imprisoned for sexual or sexually motivated offences. Principal factors analysis revealed three factors within the scale: “pressured to take part in programmes”; “fear of negative effects”; and “programme is not relevant to/appropriate for me”. Treatment refusers scored more highly than treatment accepters on the first and last components, while there was no statistically significant difference in the scores of the two groups on the “fear of negative effects” component. Suggestions for further development of the scale are discussed, along with the practice implications of these findings. 相似文献

Background. We examined the effect of a second interviewer's demeanour on cues to deception. We predicted that a supportive demeanour would be the most beneficial for eliciting verbal cues to deceit, as it would encourage truth tellers, but not liars, to say more. In addition, we examined the extent to which interviewees deliberately made eye contact with the interviewers. Liars take their credibility less for granted than truth tellers, and therefore have a greater drive to be convincing. Liars are thus more likely to monitor the interviewer to determine if the interviewer appears to believe them. Method. Participants appeared before two interviewers: the first asked all the questions and the second remained silent. The second interviewer exhibited either a supportive, neutral, or a suspicious demeanour. Results. Truth tellers provided significantly more detail than liars, but only in the supportive second interviewer condition. The effect of a second interviewer's demeanour on detail was perhaps remarkable given that the interviewees hardly looked at the second interviewer (less than 10% of the time). Liars displayed more deliberate eye contact (with the first interviewer) than truth tellers did. Conclusions. A supportive second interviewer has a positive effect on interviewing. We discuss this finding in the wider contexts of investigative interviewing and interviewing to detect deception. 相似文献
