Research on deception detection in legal contexts has neglected the question of how the use of evidence can affect deception detection accuracy. In this study, police trainees (N=82) either were or were not trained in strategically using the evidence when interviewing lying or truth telling mock suspects (N=82). The trainees’ strategies as well as liars’ and truth tellers’ counter-strategies were analyzed. Trained interviewers applied different strategies than did untrained. As a consequence of this, liars interviewed by trained interviewers were more inconsistent with the evidence compared to liars interviewed by untrained interviewers. Trained interviewers created and utilized the statement-evidence consistency cue, and obtained a considerably higher deception detection accuracy rate (85.4%) than untrained interviewers (56.1%). 相似文献

This study examines the role of the UN’s programmes for environment and development (UNEP and UNDP) in the genesis and implementation
of multilateral environmental agreements (MEAs). This is set in the wider context of the changing dominant focus of the international
agenda, from ‘environment’ at the Stockholm Conference in 1972, to ‘environment and development’ at Rio in 1992, and ‚sustainable
development’ in Johannesburg in 2002. UNDP is a development organisation strongly rooted in its country office network. Its
role is becoming increasingly normative however, particularly since 2002 when UNDP opted to root most of its activities on
the Millennium Development Goals. UNEP, as an environmental organisation has been successful at catalysing MEAs at the global
and regional level; but without a significant increase in its budget over 30 years, its capacity has been spread very thinly.
Many of the institutional arrangements for MEAs have effectively become independent of UNEP resulting in a very loosely and
sometimes poorly coordinated network. Two case studies are used to illustrate the current institutional arrangements: UNEP’s
Regional Seas Conventions and Protocols, and the Convention for Biological Diversity. These illustrate the fragmentation of
current institutions, the need for strengthened technical and scientific support, the importance of addressing problems at
their root causes and the need to increase the devolution of global governance to the regional level. Satisfying the identified
needs requires actions within the remit of both UNEP and UNDP. It is argued that current institutional arrangements have not
kept pace with the requirements of evolving policy. As part of a reform process, one option may be to merge the two programmes
into a single structure that conserves and strengthens vital technical functions but enables a balanced and integrated approach
to sustainable development. 相似文献

Seventeen Y-chromosomal short tandem repeats (STRs), DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385ab, DYS437, DYS438, DYS439, GATA-H4, DYS448, DYS456, DYS458, DYS635 were typed in DNA samples from the Kalmyk population (n=99). The population is characterized by a high proportion of duplicated DYS19 alleles and deletions of the locus DYS448 on the background of the Central Asian haplogroup C*. AMOVA analysis reveals a close vicinity to Mongolian and Kazakh populations and large genetic distance to geographical neighbours from Russia, Ukraine and the Caucasus. 相似文献

Abstract: The chemical profiling of illicit drugs is an important analytical tool to support the work of investigating and law enforcement authorities. In our work, comprehensive two‐dimensional gas chromatography–time‐of‐flight mass spectrometry (GC × GC‐TOFMS) combined with nontargeted, pixel‐based data analysis was adapted for the chemical profiling of 3,4‐methylenedioxymethamphetamine (MDMA). The validity and benefit of this approach was evaluated by analyzing a well‐investigated set of MDMA samples. Samples were prepared according to a harmonized extraction protocol to ensure the comparability of the chemical signatures. The nontargeted approach comprises preprocessing followed by analysis of variances as a fast filter algorithm for selection of a variable subset followed by partial least squares discriminant analysis for reduction to promising marker compounds for discrimination of the samples according to their chemical profile. Forty‐seven potential marker compounds were determined, covering most of the target impurities known from the harmonized one‐dimensional profiling as well as other compounds not previously elucidated. 相似文献

The external post-mortem examination, its deficient quality and possible causes have been the subject of numerous political and professional discussions. The external post-mortem examination is the basis for the decision whether further criminal investigations are required to clarify the cause of death. It is thus an essential instrument to ensure legal certainty. Before cremation, a second external post-mortem examination is performed by a public medical officer to make sure that errors of the first post-mortem are corrected. In the present study, cases were retrospectively analyzed in which a forensic autopsy had been ordered on the basis of the results of the post-mortem examination performed before cremation. The entries on the death certificate regarding the manner and cause of death were compared with the autopsy results. Between 1998 and 2007, 387 autopsies were ordered after external examination before cremation. In 55 cases (14.2%), the autopsy revealed a non-natural death, although a natural death had been attested on the death certificate. In descending order, a wrong manner of death was attested by clinicians, general practitioners and emergency physicians. With regard to the place where the first external post-mortem had been performed the lowest error rate was seen in nursing homes. Concerning the cause of death, discrepancies between the first post-mortem and autopsy were found in 59.4% of the cases. In this respect, general practitioners and clinicians were ranking first, whereas in nursing homes the cause of death was wrongly assessed in over 70% of cases. At present, the medical post-mortem does not meet the required quality standards, especially with regard to legal certainty. Determination of the cause of death on the basis of the external post-mortem examination is a challenging task even for the experienced medical examiner. As to the categorization of the manner of death it has to be stated that non-natural deaths are often not recognized or that the possibility to certify a death as unclear is not sufficiently used. As a result, it seems important to demand intensive, qualified, additional training in external post-mortem examinations for physicians. 相似文献
