Debates over the future of new technologies frequently implicate governmental policies and regulation, the purpose of which has traditionally been to mitigate the dangers of new technologies through promotion of conditions of safe use. It is increasingly recognized, however, that regulation is predicated on a particular conception of the nature of risk which may or may not correspond to the views and beliefs held by society. Here I explore three broadly related questions in the context of the debates around agricultural biotechnology. First, what are the implications of varying conceptions of risk for regulatory policy in the United States and in the European Union? Second, what are the implications of differing conceptions of risk and resulting regulatory policy for agricultural trade relations between the two giants of international trade? And finally, what lessons might we draw from contemporary disputes over agricultural biotechnology?  相似文献

In child sexual exploitation offenses, the collected evidence images often show the skin of nonfacial body parts of the criminals and victims. For identification in this scenario, “relatively permanent pigmented or vascular skin marks,” abbreviated as RPPVSM, were recently introduced as the basis for a novel biometric trait. This pilot study evaluated the interexaminer variability of RPPVSM identification. Four dermatology physicians were recruited to examine RPPVSM from 75 skin images collected from a total of 51 Caucasian and Asian subjects. The images were separated into 50 reference (“suspect”) images and 25 evaluation (“evidence”) images. The examiners were asked to perform identification by annotating RPPVSM in each of the 25 evaluation images and matching them with the reference images. The rate of misidentification was 0% while the mean rate at which examiners failed to find a match was 6%, indicating the potential of dermatology physicians performing the role of RPPVSM examiners.  相似文献

Potent synthetic opioids including fentanyl and its analogs are frequently encountered in the field and require detection and identification by first responders to maintain the safety of drug abusers, first responders, health-care providers, and the public at large. Due to the low concentration at which these substances may be encountered and the complicating matrices within which they may be dispersed, the use of portable gas chromatography–mass spectrometry (GC–MS) for their identification in the field offers great potential value. This research established that portable GC–MS is a useful method for the detection and identification of a large number of synthetic opioids, especially fentanyl and its analogs. In this study, 250 synthetic opioids and related substances including 210 fentanyl analogs were analyzed using portable GC–MS. It was concluded that 225 of the 250 (90.0%) opioids analyzed were successfully detected onboard at the time of analysis and identified as either the substance (55.2%) or an analog (34.8%). These outcomes have equivalent benefit for the field analysis of illicit drugs due to both initiating the same subsequent actions by first responders.  相似文献

Norm contestation by local actors has emerged in recent years as an explanation for the failure of norm diffusion. This article contributes to the literature on norm contestation by analysing how norms diffused by the Organisation for Security and Cooperation in Europe (OSCE) pertaining to election observation and free and fair voting are re-constituted and contested by domestic actors in Kazakhstan. The study contributes to the idea of ‘constitutive localisation’ by emphasising a more fundamental level of disagreement beyond just congruence between the diffused norm and local beliefs; by demonstrating contestation can occur in the later stages in the norm diffusion cycle; by focusing on the micro-politics of contestation by local actors involved in the implementation of diffused norms; and by revealing how norm contestation is not necessarily a process of emancipatory politics, but a strategic act to serve authoritarian consolidation. Utilising a four-fold framework, the analysis illustrates how norms, while initially accepted by Kazakhstani authorities, are reconstituted through political discourse and/or practice, creating the moment of contestation. While this contestation is instrumentalised by political elites for their own advantage, it also remains an important element of agency within a normative order which they had little previous control over.  相似文献

Purpose

Classic criminological theories emphasize the role of impaired self-control in behavioral deviancy. Reduced amplitude of the P300 brain response is reliably observed in individuals with antisocial and substance-related problems, suggesting it may serve as a neurophysiological indicator of deficiencies in self-control that confer liability to deviancy.

Methods

The current study evaluated the role of self-control capacity—operationalized by scores on a scale measure of trait disinhibition—in mediating the relationship between P300 brain response and behavioral deviancy in a sample of adult twins (N = 419) assessed for symptoms of antisocial/addictive disorders and P300 brain response.

Results

As predicted, greater disorder symptoms and higher trait disinhibition scores each predicted smaller P300 amplitude, and trait disinhibition mediated observed relations between antisocial/addictive disorders and P300 response. Further, twin modeling analyses revealed that trait disinhibition scores and disorder symptoms reflected a common genetic liability, and this genetic liability largely accounted for the observed phenotypic relationship between antisocial-addictive problems and P300 brain response.

Conclusions

These results provide further evidence that heritable weaknesses in self-control capacity confer liability to antisocial/addictive outcomes and that P300 brain response indexes this dispositional liability.  相似文献
