Over the last decade, the need for governance of human health and environmental safety risks of nanotechnology (NT) has received increased attention at international, national and EU levels. There were early calls for increased funding of independent research, risk analysis and voluntary or mandatory regulation, but currently overall regulatory efforts have not materialised. One possible explanation is that research has revealed little need to regulate environmental and health safety risks of NT. Alternatively, there is a gap between politics and governance and the evolving state of knowledge. Such a gap can be caused by various factors including change in interests, saliency and organisation. Organisational challenges related to the science–policy interface at national, international and the EU can affect how new knowledge is channelled into decision-making processes. Decrease in public saliency is another possibility. Finally, opposition to regulation among affected producers may have increased and in turn stalled regulation through lobbying. The two explanations are analysed in a multi-level governance context. Norway is chosen as an interesting case: Highly profiled as a frontrunner i.a. in regulating gene technology, but currently awaiting regulations in the EU due to the European Economic Area agreement.  相似文献

Endowed with the state monopoly on the legitimate use of even potentially lethal force, it is intolerable for police officers to act outside the governing legal and ethical framework. At the same time, officers are expected to exert self-control and refrain from excessive use of force when they deal with provocative and perilous situations. This study sought to investigate corresponding self-control and self-control failures through the role of ego depletion in the decision to use force by police officers. Two experiments were conducted using officers from a German State Police force, requiring the participants to use force against a provocative role player. Experiment 1 found that the ego depletion measure failed and there were no differences between the groups. Using a different ego depletion method, experiment 2 found that ego-depleted participants aggressed earlier than controls. These results indicate that circumstances that produce ego depletion could lead to the inappropriate use of force through reducing self-control. This has major implications for the police use of force and how we understand police officers’ decision-making in response to provocation.  相似文献

Using concepts drawn from situational crime prevention theory, this study compares successful and unsuccessful pirate attacks (n = 4,638) against ships worldwide and the situational factors that help prevent such attacks. The results show that when a ship’s crew takes proactive self-protective measures that increase the perceived effort (increasing speed, employing evasive maneuvers) and increase the perceived risk (embarking private security, having watchman present, raising alarm, increasing lighting, anti-piracy) of perpetrating an attack, unsuccessful attacks are significantly more likely after controlling for environmental influences. Despite a few common data limitations, the study contributes to the crime prevention literature by analyzing piracy from a micro level instead of a macro level. Future research should examine how the piracy “ecosystem” contributes to the problem and the costs and benefits counter-piracy activities.  相似文献

A sample of 276 professionals described how they spend their professional time, their attitudes and knowledge about etiology and treatment of sexual abuse. Professionals were also asked to respond to a case vignette where varied on two dimensions: age of the child victim and relationship of the offender to the victim. Agencies receiving the questionnaire were randomly assigned to one of the six possible scenario conditions resulting from the two dimensions.  相似文献
