Two European Union (EU) directives on labour migration were adopted in 2009 and 2011. The EU scheme to attract highly qualified migrants, the so-called ‘Blue Card’ directive of 2009, allows member states broad flexibility in implementation. In contrast, the directive on a single permit for migrant workers and their rights of 2011 is far less flexible. It does significantly reduce the scope for derogations at a national level to a minimum. How can this variance in output be explained? Institutional rules are shown to be a key factor. The involvement of the European Parliament as co-legislator alongside the Council limited member states’ influence on legal outputs. The comparison of policy outputs between the two cases points to differences in actor orientations: rather than seeking to increase labour migration into the EU by defining expansive admission conditions, the common EU policy seeks to include migrant workers by defining their rights.  相似文献

All objects radiate infrared energy invisible to the human eye, which can be imaged by infrared cameras, visualizing differences in temperature and/or emissivity of objects. Infrared imaging is an emerging technique for forensic investigators. The rapid, nondestructive, and noncontact features of infrared imaging indicate its suitability for many forensic applications, ranging from the estimation of time of death to the detection of blood stains on dark backgrounds. This paper provides an overview of the principles and instrumentation involved in infrared imaging. Difficulties concerning the image interpretation due to different radiation sources and different emissivity values within a scene are addressed. Finally, reported forensic applications are reviewed and supported by practical illustrations. When introduced in forensic casework, infrared imaging can help investigators to detect, to visualize, and to identify useful evidence nondestructively.  相似文献

Research on deception has consistently shown that people are poor at detecting deception, partly due to lack of consistent cues to deception. This research focuses on eliciting verbal cues to deception when questioning suspects who deny crime and how such cues differ due to type of questioning. An experiment examined verbal differences between innocent and guilty mock suspects (N=96) as a function of veracity and interview style (Free recall, Probes, or Free recall plus Probes). Guilty (vs innocent) suspects omitted more crime-relevant information and their statements were more likely to contradict the evidence, showing that statement–evidence inconsistency was a cue to deception. This cue to deception was more pronounced when the interview contained probes. Lie-catchers (N=192) obtained an accuracy rate higher than chance (61.5%) for detecting deceptive denials. Implications for further research on verbal cues to deception are discussed.  相似文献

Abstract

In order to obtain the most informative and correct statements, witnesses should be heard as soon as possible after the incident. However, this is not always possible. This experimental study investigated whether completing a Self-Administered Interview form (SAI) immediately after a critical event could enhance children's witness performance at a later stage. Children (N = 194, age 11–12) reported their memory of an event in a structured SAI, an open SAI, or did not report their memory (control). Two weeks later, the children were interviewed about the event. Before the interview, half of the children were subjected to social influence from a co-witness. Children's free recall of the event was enhanced by the SAI. More precisely, children in the SAI-Structured condition reported more details about the event than children in the SAI-Open condition and the control condition, without a loss of accuracy. The SAI manipulation did not, however, reduce children's vulnerability to social influence. The results suggest that the use of a SAI might prove a simple and yet effective way of increasing the quality of statements from child witnesses in some situations.  相似文献

Alcohol affects memory in many, and mostly negative, ways. This is a problem in legal contexts as many witnesses are alcohol intoxicated when taking part of the critical event. However, research is sparse regarding how, and under what circumstances, the reports of alcohol intoxicated witnesses differ from those of sober witnesses. This study investigated whether alcohol intoxicated and sober eyewitnesses differ regarding completeness, accuracy, and type of information reported, as well as whether gender influenced these variables. Eighty-seven healthy men (n = 44) and women (n = 43) received either an alcoholic beverage (0.7 g/kg) or a control (juice) in a laboratory setting before viewing a film picturing intimate partner violence. Ten minutes after viewing the film, they were interviewed. Reports by alcohol intoxicated women were less complete, but as accurate, as sober women's. In contrast, intoxicated and sober men did not differ regarding completeness or accuracy. Furthermore, compared with sober women, intoxicated women reported fewer actions but no difference was found between the groups regarding reported objects. At this moderate dose, alcohol affected women's reports more than men's, which may be because alcohol affects attention and memory consolidation more clearly at a lower dose for women than for men.  相似文献

This paper suggests applying experimental and quasi-experimental approaches to the study of environmental problems. Some important issues in quasi-experimentation are outlined and strategies appropriate for research on collective goods highlighted. Studies both of the demand for various underpriced goods and of programs for changing usage of a collective good are suggested. Questions of causality are treated in some detail. The logic of a new quasi-experimental design, the event-causing design, is presented and compared with that of the interrupted time-series design. Problems of site selection are discussed in terms of the types of projects for which random assignment of sites might be possible. New combinations of experimental and analytical techniques are suggested for improving the quality of research on environmental problems.  相似文献

Economists assume that individuals think about the economy like economists, which is especially important in all rational expectations and economic voting models. Despite contrasting evidence, there has been little research on actual nonexpert macroeconomic beliefs. In this paper, I present the results of a survey among students designed to find out whether they distinguish macroeconomically relevant from irrelevant events. I find that even people with some economic background tend to overestimate the effects of noneconomic events. This bias is a function of gender, economic training, and the preferred means of mass communication.  相似文献
