The Indiana University Advanced Research and Technology Institute (ARTI) is the technology transfer organ of the Indiana University system. ARTIs structure is complex, and has been dynamic since its creation in 1996. This complexity stems in part from the diversity represented by the Indiana University system and from competing interests within the university itself. In addition to the intrinsic value of higher education, the university has the potential to add substantial value to Indianas economic landscape through technology transfer, economic development initiatives and the resulting job creation, but realizing that potential will require effectively leveraging a disconnected network including the IU campuses and critical capabilities contributed by the states other world class institutions. This paper reviews the formation of ARTI, a discussion of its structure and evolving mission, recent initiatives and some possible metrics for technology transfer initiatives.  相似文献

Relationships among Structured Interview of Reported Symptoms (SIRS) scores and Minnesota Multiphasic Personality Inventory--2 (MMPI-2) F(p) and F scores were examined for 63 suspected malingerers evaluated at either of two psychiatric facilities. Despite differences between facilities in terms of seriousness of subjects' offenses, mean scores on the malingering tests were similar. Cutting scores for F(p) and F resulting in substantial correspondence between these scales and the SIRS were derived. Use of the cut score for F(p) proposed by Arbisi and Ben-Porath (1995) resulted in less agreement with the SIRS than did a lower cut score. No substantial difference between F(p) and F in each scale's overall agreement with the SIRS was observed. A principal components analysis of the SIRS primary scales produced two factors, interpreted as Overreporting of Symptoms and Implausible Symptoms. F(p) was observed to correlate significantly with Implausible Symptoms but not with Overreporting of Symptoms; F was significantly correlated with both factors.  相似文献

Suffocation by inhaled gases has been reported involving a variety of gases. We report a case of suicidal asphyxiation by forced replacement of oxygen with helium by using a complex homemade mask. In this case, a young woman researched suicide on the Internet and found an advocated method of suicide using helium. To our knowledge, there is only 1 previously reported case of suicidal asphyxia by using helium.  相似文献

There has been an increased focus on child custody evaluations involving domestic violence allegations with much criticism of evaluators' training, practices, and procedures. A national survey of 115 child custody evaluators (doctoral and master's level) was conducted to explore these criticisms. Findings revealed adequate training, multiple sources of data collection, and practices/procedures that closely adhere to child custody guidelines. However, robust, specialized domestic violence instruments, tests, and questionnaires were underutilized. Respondents indicated that findings supporting domestic violence allegations had a substantial impact on their subsequent recommendations. Results are discussed in terms of the importance of assessing domestic violence when conducting custody evaluations and the need for developing practice standards in this domain. Generally, results did not support common criticisms of custody evaluation practice.  相似文献

This article argues that existing Australian regulations do not adequately cover online pharmacies or Internet advertising of medicines and that existing penalties and sanctions are often ineffective, potentially placing public health and safety at risk. Suggestions are made for future regulatory approaches. It is concluded that as well as an effective program of public education, cautious domestic legislative reform is necessary to ensure specific regulation of Australian online pharmacy practice and Internet advertising of medicines. In addition, the global nature of the Internet demands international co-operation and increased regulator and consumer vigilance.  相似文献

Supraphysiologic doses of testosterone are associated with increased aggression that is hypothesized to be a function of testosterone serum concentrations, mood, and personality. The study attempted to characterize this relationship among weightlifters who were users (n = 10) and nonusers (n = 18) of anabolic steroids. Participants were interviewed using the Modified Mania Rating Scale and Hamilton Rating Scale for Depression to assess mood, the Buss-Durkee Hostility Inventory (BDHI) and Point Subtraction Aggression Paradigm (PSAP) to assess aggression, and the Personality Disorder Questionnaire (PDQ-R) to assess personality. Blood samples were obtained for the determination of total, free, and weakly bound testosterone. Comparisons of continuous variables between testosterone users and non-users were performed with a parametric (unpaired t-test) or non-parametric (Mann-Whitney) test where appropriate. Correlations with testosterone were examined separately for testosterone users and non-users, using Spearman rank correlation. The subjective (BDHI) and objective (PSAP) assessments of aggression found that supranormal testosterone concentrations were associated with increased aggression. However, the PDQ-R results suggest that this finding was confounded by the personality disorder profile of the steroid users, because steroid users demonstrated Cluster B personality disorder traits for antisocial, borderline, and histrionic personality disorder.  相似文献

Sovereignty remains the key concept and principle accordingto which the world is ordered. But sovereignty is also a disputedconcept and a contested social practice; it has come under fierceassault from a number of diverse sources. Sovereignty is paradoxicalin nature and hypocritically practised. States have differentempirical degrees and qualitative types of sovereignty, rangingfrom the merely formal to the substantial to the popular. Statesalso have different dispositions towards sovereignty, and areliable to project their own in different ways in pursuit ofconflicting objectives. Different groups of states attempt toimpose their understandings and beliefs on the internationalsystem. There are three ideal types which help us to understandthe issue of sovereignty and the interactions of sovereign states.These are respectively Westphalian, liberal and anti-utopian.The Westphalian paradigm has the maintenance and protectionof state sovereignty as its key concept. The liberal paradigmis conceived in terms of the concept of popular sovereigntyand controversies over the extent to which this ideal shouldbe promoted and exported. The anti-utopian paradigm is conceivedin terms of the concept of quasi-sovereignty or the loss ofsovereignty, and in terms of resistance to attempts to imposeglobalization and liberal values on recalcitrant states andcultures.  相似文献

It has been estimated that deregulation of US S&Ls will cost the US taxpayer £500bn in terms of the compensation paid out for the resulting scandals and failures. In contrast, the deregulation of UK building societies, although initially followed by a series of scandals and losses of £1bn., eventually resulted in substantially increased profitability. The social effects in the UK have been quite different to those in the US. As a result of the increased importance placed on profitability as opposed to mutuality, many homeowners have had their properties repossessed, and investors been mis-soId unsuitable investments. However, UK building societies, by a mixture of good luck and judgement, have avoided the principal regulatory pitfalls, which beset the S&Ls in terms of bankruptcies and fraud. This paper seeks to explain these different post-deregulation experiences. It extends to the UK the looting model of Akerlof and Romer (1993) and the managerial diversion model of Nichols (1972) which went so far to explain and anticipate, respectively, the US experience. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

The introduction of the national minimum wage in the United Kingdom poses a new challenge for labour law because of its novel enforcement methods. This article examines carefully the possibilities for enforcing the new statutory minimum wage in the light of regulatory theory and the government's desire to make the wage 'self-enforcing'. It offers policy suggestions as to how the different enforcement strands can be best made to work together and highlights some of the dangers the government needs to be aware of in this area.  相似文献
