Human provenance studies employing isotopic analysis have become an essential tool in forensic and archaeological sciences, with multi-isotope approaches providing more specific location estimates compared to single isotope studies. This study reports on the human provenancing capability of neodymium isotopes (143Nd/144Nd), a relatively conservative tracer in the environment. Neodymium isotope ratios have only recently been determined on human remains due to low concentrations in human dental enamel (ppb range), requiring thermal ionisation mass spectrometry (TIMS) using 1013 Ω resistors. Dental elements (third molars) from 20 individuals born and raised in the Netherlands were analysed for Nd concentration (n = 12) and Nd isotope ratios (n = 15). The geological control on Nd isotope composition was examined using coupled Nd-Sr isotope analysis of the same third molar. Teeth from different geological environments were also analysed (Caribbean, Columbian, and Icelandic, n = 5). Neodymium elemental concentrations in dental elements ranged between 0.1 and 7.9 ppb (median 0.5 ppb). The Dutch 143Nd/144Nd ratios of the provinces of Limburg and Friesland were between 0.5118 and 0.5121, with Dutch 87Sr/86Sr ratios in agreement with the previously established local range (0.708–0.710). The current findings were compared to previously published results on Nd concentration and composition from Dutch individuals. The concentration of Nd and 143Nd/144Nd ratios were weakly correlated (R2 = 0.47, n = 17) in Dutch human dental enamel. The majority (n = 25, 83.3%) of individuals had Nd and Sr isotope values isotopically indistinguishable from the geological environment in which their third molars formed and mineralised. However, the Nd isotope ratios of the Icelandic individual and several Dutch individuals (n = 4) suggested that Nd in enamel is not solely influenced by geological environment. In order for neodymium isotopes to be quantitatively applied in forensic and archaeological settings further analyses of individuals from various geographical regions with well-defined dietary Nd isotope data are required. 相似文献

Purpose. The current study explored how misleading information affects children's omissions and commissions over time. Method. Fifty‐nine younger (Mage = 4.16) and fifty‐nine older (Mage = 9.44) children were instructed to remove three pieces of clothing from a puppet. Half of them were provided with false evidence that they had removed only two items, while the other half were provided with false evidence that they had removed a fourth piece of clothing. In three neutral interviews separated by 1‐week intervals, children had to report which pieces of clothing they had removed. Results. Overall, omission and commission errors significantly decreased over time, although this pattern was more pronounced for omission errors. Younger and older children were equally likely to make omission errors, whereas commission errors were more typical for younger than for older children. Also, we found that commission errors more readily occur than omission errors. Conclusion. Even when children's memory reports pertain to an event in which they actively participated, misleading information may elicit omission and commission errors, with especially the latter category being very persistent over time. 相似文献

Abstract The present paper describes three studies that examined false confessions in the laboratory. Studies 1 (N=56) and 2 (N=9) relied on the by now classic computer crash paradigm introduced by Kassin and Kiechel (Psychological Science, 7, 125–128, 1996). Study 3 (N=12) employed a novel paradigm in which undergraduate participants were falsely accused of exam fraud. Our data indicate that false confessions do occur, even when conditions become more ecologically valid. Furthermore, we explored whether individual differences in compliance, suggestibility, fantasy proneness, dissociation, and cognitive failures are related to false confessions. Of these, only fantasy proneness was associated with false confessions. 相似文献

This article traces the role of the EU institutions in the process leading up to the EU–Turkey Action Plan and EU–Turkey Statement. The EU–Turkey deal is the proverbial ‘orphan’ in EU crises management, with none of the key actors and institutions eager to claim ownership. Yet when judged from the perspective of process management, the deal resulted from effective inter-institutional collaboration, which stands in stark contrast to the EU’s handling of the relocation schemes or the Dublin reform. Using insights from the informal governance literature, the article maps the inter-institutional network that managed this process, traces the activities within the network, and determines the effects these had on the final outcome. On an analytical level, the mechanism contains five key elements of informal institutional governance: linking, bridging, shielding, laying out the tracks and creative fixes. The conclusion reflects on the wider applicability and scope conditions of this mechanism. 相似文献

How are unanimity negotiations commonly settled in the EU Council of Ministers? Important contributions have been made to our understanding of the ‘consensual’ decision‐making dynamics in the Council, but most studies focus on explaining the sheer absence of votes in legislative decision making under the qualified majority rule. This study seeks to explain how vetoes are averted, or curtailed, in unanimity decision making. These unanimity negotiations are explained as attempts to induce or prevent high‐level exposure. The degree of exposure in turn depends on the degree of lower level contestation. A process tracing analysis of one prolonged debate is performed from the perspective of one Member State – the Netherlands – which played a very prominent obstructing role. By analysing when, why and where (at what level) the Dutch won or lost, one can come closer to understanding the dynamic interplay between the different Council levels. 相似文献

Purpose. This study examined whether people can successfully feign high levels of interrogative suggestibility and compliance as measured by the Gudjonsson Suggestibility Scales (GSS) and the Gudjonsson Compliance Scale (GCS) when given instructions to malinger. Methods. Participants (N = 90) were randomly allocated to one of three groups that received: (1) instructions to give into leading questions in order to look vulnerable to suggestions, (2) instructions to be compliant with the examiner, or (3) the standard GSS/GCS instructions. Results. One of the two malingering instructions led to modestly elevated scores of total suggestibility, while subscales remained unaffected. In contrast, both malingering groups obtained highly elevated compliance scores. Conclusions. These findings suggest that heightened suggestibility is rather difficult to malinger, thereby confirming the reliability of the GSS. On the other hand, it might be easier to malingering compliance as measured with the self‐report GCS. 相似文献

Empirical studies estimating shift‐parameters to evaluate the ‘true protection’ especially for developing countries often reach the result that those parameters have very high values. This study is to show that it is not substitutional relationships but much more the very inflationary monetary policy of many developing countries which forces the shift‐parameters towards one. Moreover it is shown that it makes little sense to distinguish between ‘traditional’ and ‘non‐traditional’ exports and that shift‐parameters are not necessarily stable over time. 相似文献

Purpose. The Gudjonsson Suggestibility Scale (GSS; Gudjonsson, 1984, 1997 ) is a well‐established forensic tool for measuring interrogative suggestibility. However, one restriction of this tool is that it requires an extensive testing procedure. The present study examined whether shorter versions of the GSS yield similar results as the original GSS procedure. Methods. One group (N=20) was given a shortened version of the GSS that consisted of an immediate recall test and the specific questions. GSS scores in this group were compared with those in a group (N=20) that had the standard procedure which includes a retention interval and immediate and delayed recall tests. A third group (N=20) was administered a shortened procedure in which the 20 GSS questions immediately followed the GSS story. In the fourth group (N=20), participants were given the retention interval, but no recall tests were administered. Results. ANOVA showed no differences in GSS scores amongst the four groups. Post hoc power analyses indicated that these non‐significant findings were not the result of a power problem and that larger sample sizes are expected to yield comparable results. Further analyses showed that neither the retention delay nor the recall tests affected suggestibility scores. Conclusions. These results suggest that shortened procedures for administering the GSS may be employed in situations where time is a key factor. 相似文献
