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

When I was in high school, I went on a family vacation to Ocho Rios, Jamaica. I was getting lunch at a grilled chicken stand, when the cook asked me, "Miss Chin, where are you from?" (Jamaicans use Miss Chin as an affectionate nickname for all Chinese women.) I answered, "I’m from New Jersey, but I’m Korean." He practically dropped his spatula. "Whaaaat? I never met Korean Japanese Miss Chin fromNewJersey!"heshouted.Thatwas the only time I’ve had someone 相似文献

We model two aspects of executives in parliamentary democracies: Decision‐making authority is assigned to individuals, and private information is aggregated through communication. When information is relevant to all policies and communication is private, all decisions should be centralized to a single politician. A government that holds cabinet meetings, where information is made available to all decision makers, outperforms one where communication is private: A multimember cabinet can be optimal; it need not be single peaked around the most moderate politician or ideologically connected. Centralization is nonmonotonic in the degree of ideological divergence. In a large cabinet, all power should be given to the most moderate politician. Even when uncertainty is policy specific and a single politician is informed on each policy, power should never be fully decentralized. Our model provides a justification for centralized authority and cabinet meetings that enhance the quality of policy. 相似文献

The term ‘robot’ refers to a wide variety of devices, serving very different purposes. The case of robotic prostheses is considered here. After defining such devices, and briefly describing the technical peculiarities that characterize their functioning and distinguish them from traditional implants, their relevance with respect to the fundamental rights of people with disabilities is considered. Pursuant to the United Nations Convention on the Rights of Persons with Disabilities, a claim is made that favouring the development of said applications may be required to subscribing states. In light of such considerations, the liability regime – namely that emerging from the Defective Product Directive – is analysed, in the attempt to determine – with a prospective analysis – the impact that said rules are likely to have on their development. The technology-chilling effect and the anticipated extremely complex evidentiary burden the user would have to face in order to obtain compensation lead us to conclude that legal reform is advisable. Some alternatives are considered, and in particular that of the development of a – partially – state-funded no-fault plan, intended to allow more ex ante certainty for producers and researchers (favouring the development of said devices), and prompt and adequate compensation to the victim in case an accident occurs. 相似文献

In some countries, it is illegal to drive with any detectable amount of alcohol in blood; in others, the legal limit is 0.5 g/L or lower. Recently, some defendants charged with driving under the influence of alcohol and have claimed that positive breath alcohol test results were due to the ingestion of homeopathic mother tinctures. These preparations are obtained by maceration, digestion, infusion, or decoction of herbal material in hydroalcoholic solvent. A series of tests were conducted to evaluate the alcoholic content of three homeopathic mother tinctures and their ability to produce inaccurate breath alcohol results. Nine of 30 subjects gave positive results (0.11–0.82 g/L) when tests were taken within 1 min after drinking mother tincture. All tests taken at least 15 min after the mother tincture consumption and resulted in alcohol-free readings. An observation period of 15–20 min prior to breath alcohol testing eliminates the possibility of false-positive results. 相似文献
