A decade of spectacular progress in functional magnetic resonance imaging (fMRI) technology and systems neuroscience research has so far yielded few changes in our daily lives. The dearth of clinical applications of this prolific and academically promising research tool began raising the eyebrows of the public and the research funding agencies. This may be one of the reasons for the enthusiasm and interest paid to the growing body of literature suggesting that blood oxygenation level‐dependent (BOLD) fMRI of the brain could be sensitive to the differences between lie and truth. The word ‘differences’ is critical here since it refers to the often‐ignored core concept of BOLD fMRI: it is only sensitive to differences between two brain states. Thus, available studies report using fMRI to discriminate between lie and truth or some other comparative state rather than to positively identify deception. This nuance is an example of the extent to which applied neuroscience research does not lend itself to the type of over‐simplification that has plagued the interpretation of fMRI‐based lie detection by the popular press and the increasingly vocal academic critics. As an early contributor to the modest stream of data on fMRI‐based lie detection, I was asked by Dr Aldert Vrij to write a piece in favour of fMRI‐based lie detection, to be contrasted with a piece by Dr Sean Spence presenting an opposite point of view ( Spence, 2008 ). This seemingly straightforward task presented two hurdles: having to respond to the popular as well as scientific view of what lie detection with fMRI is and present a wholly positive view of evolving experimental data.  相似文献

Drawing on fieldwork and political theory with Lacanian psychoanalytic influences, this article analyzes how fantasy and fetishes help sustain strategies shown to be no solution to U.S. border control problems. More than a decade after the official launch of the border control paradigm of “prevention through deterrence,” predicated on the assumption that ramping up walls, barriers, policing, and the human costs of border crossing would deter, there has been scant evidence of deterrence and much evidence of diversion of migrants to more dangerous crossing points where death rates have soared. Attempts to mitigate the cost to life have also proved ineffective but have persisted alongside the policy of diversion. The article is based on research in a region where the reality of diversion and death instead of deterrence was lived but where people still pursue projects of barrier‐building and death mitigation that they know to be ineffective. The article analyzes how fantasy fuels action despite knowledge and occludes a traumatic element around which the symbolic order of border law is structured: the foundation of “good life” with its bounty of rights, privileges, and opportunity on the exclusion of basic life denuded of the entitlements that make the good life sweet. The article also examines how fetishes are used to cope with unrealized hopes and to diffuse the impact of the traumatic knowledge that good life is undergirded by the exclusion and even death of basic life.  相似文献

The Wanderers     
JEFFREYS  M. D. W. 《African affairs》1946,45(178):37-41
Dr. Jeffreys writes to say that he would be interested to hearof any other tribe whose name is a sobriquet for "wanderer"or "stranger". He has not dealt with Southern Africa, and wewould therefore suggest Angoni. Any reader who can add to thelist may care to get into touch with the writer of this articleat Bamenda, British Cameroons.  相似文献

Although there is an already large British literature both supporting and attacking left realism, and a growing North American interest on the subject among criminologists, there has been surprisingly little written which attempts to locate both the strengths and weaknesses of the left realist position on crime control. Perhaps the place where the left realists may be weakest is in response to a feminist critique. Actually, it is not only left realism but the socialist left in general which has been unsuccessful in providing adequate responses to the issues brought forth by feminists. This paper attempts to locate the position of left realism within the left criminology debate, and to find its strong and weak points. Further, it attempts to explicate the feminist critique, and to suggest responses critical criminologists might explore, such as those proposed by peacemaking criminology. *** DIRECT SUPPORT *** AW502012 00004  相似文献

When Hurricane Katrina made landfall on the Mississippi Gulf Coast in August 2005, it immediately overwhelmed the abilities of local and state emergency management officials to respond to the ensuing disaster. Although the U.S. Coast Guard and some military units were on scene shortly after the passage of the storm, there seemed to be interminable delays before the military forces began to arrive in numbers to both provide humanitarian relief and secure the affected areas. This article analyzes the response of the National Guard, active-duty military, and Coast Guard forces through the lens of coordination. We find evidence of the successful use of both traditional hierarchical and network-based coordination; we also find support for Donald Kettl's idea of "contingent coordination."  相似文献

There is mounting evidence that HIV infection among adolescents is increasing, particularly among minorities and inner-city youths involved in certain high-risk activities, such as multiple sex partners and intravenous drug use. Interviews conducted “on the street” with 611 seriously delinquent male and female adolescents (ages 12–17) included questions about their involvement in prostitution, intravenous drug use, and sex-for-crack exchanges. Findings included high percentages of youths engaged in these HIV-risk activities and a consistent association between all of them and greater illicit drug use. This would suggest that these risk behaviors may be surprisingly prevalent among some inner-city adolescent groups. Special AIDS prevention/intervention targeting these groups is warranted and urgently needed. Drug treatment should be a central focus of such programs.  相似文献

A simple and reliable previously reported extraction procedure has been extended to the analysis of a wide range of basic and neutral drugs in postmortem blood and other tissues. The method employs 200 microliters of blood treated with water and ammonia and extracted with diethyl ether. The concentrated extract is generally sufficiently clean for direct analysis by gas chromatography and high pressure liquid chromatography. Recovery, precision and linearity data are presented for selected drugs.  相似文献
