Fledgling psychopathy is a construct that has proven useful in organizing the nomological network of conduct problems and psychopathology in children and adolescents. Drawing on data from an institutionalized sample of delinquents (n?=?252), the current study compared ADHD, CD, and ADHD+CD youth on psychopathic personality features and their association with pathological delinquency. Youths with ADHD+CD were significantly more psychopathic than their peers. Although callousness, unemotionality, and remorselessness are generally theorized to define the fledgling psychopathic youth, ROC-AUC models found that thrillseeking and impulsiveness were the strongest classification variables for delinquency and violent delinquency at the 90th percentiles. Implications for research and practice with antisocial youth are proffered.  相似文献

Victimology theory recognizes that the characteristics, attitudes, and behaviors of potential victims influence the likelihood of criminal victimization. An important question for victimologists is whether potential victims put themselves at risk by engaging in risky behavior or whether victimization is primarily a result of bad luck. While this question has been investigated extensively with respect to street crime victimization, little attempt has been made to apply it to victimization by fraud. This article investigates the influence of attitudes toward financial risk taking on the likelihood of fraud victimization. Using data from a telephone survey of 400 randomly sampled respondents, we find that age and attitudes toward financial risk taking are significantly related to the likelihood of attempted victimizations but not to successful victimizations.  相似文献

In this paper, we employ resource-based and institutional theories to examine the current role of business schools in academic entrepreneurship. In particular, we seek to identify and understand the challenges to business schools contributing to the transfer of knowledge to enable academic entrepreneurship. Employing a case-based method, we present evidence from 42 interviews with technology transfer officers (TTOs), business school deans, business school entrepreneurship faculty and scientists in eight UK universities. Our empirical analysis is focused on analyzing the challenges arising from the links between business schools and three other principal stakeholders of academic entrepreneurship (i.e., the university management, TTOs and academics in science departments). The findings suggest that in addition to concerns about the nature of their human capital, the ability of business schools to fill knowledge gaps in the development of academic entrepreneurship is constrained by the institutional structures of universities which influence: the strategies of the university and the business school; links between business schools, TTOs and scientists; and process issues relating to differences in language and codes, goal differences, incentives and rewards, expertise differences and the content of interactions. We conclude that if business schools are to play a more prominent role in academic entrepreneurship there is a need to develop internal university processes and policies that promote rather than hinder internal knowledge flows between business schools, TTOs and science departments.  相似文献

Abstract:  Comparability of data over time and between laboratories is a key issue for consideration in the development of global databases, and more broadly for quality assurance in general. One mechanism that can be utilized for evaluating traceability is an inter-laboratory trial. This paper addresses an inter-laboratory trial conducted across a number of Australian and New Zealand isotope ratio mass spectrometry (IRMS) laboratories. The main objective of this trial was to determine whether IRMS laboratories in these countries would record comparable values for the distributed samples. Four carbon containing and four nitrogen containing compounds were distributed to seven laboratories in Australia and one in New Zealand. The laboratories were requested to analyze the samples using their standard procedures. The data from each laboratory was evaluated collectively using International Standard ISO 13528 ( Statistical methods for use in proficiency testing by inter-laboratory comparisons ). "Warning signals" were raised against one participant in this trial. "Action signals" requiring corrective action were raised against four participants. These participants reviewed the data and possible sources for the discrepancies. This inter-laboratory trial was successful in providing an initial snapshot of the potential for traceability between the participating laboratories. The statistical methods described in this article could be used as a model for others needing to evaluate stable isotope results derived from multiple laboratories, e.g., inter-laboratory trials/proficiency testing. Ongoing trials will be conducted to improve traceability across the Australian and New Zealand IRMS community.  相似文献

In this paper we use a size and industry matched sample of over 1,900 UK and US businesses for the period 2004–05 in the manufacturing and business services sectors to analyse the relative “strength” of the university–industry ecosystems in which these firms operate in the two economies. Our analysis shows that in both countries universities per se play a quantitatively smaller role as a source of knowledge for business innovation than either the business sector itself or a variety of organisations intermediating between the university and business sectors. Our analysis reveals a much more diffuse university–industry ecosystem in the UK in which a higher proportion of businesses claim links external to themselves in their pursuit of knowledge for innovation and a higher proportion report directly connecting with universities. US firms are more likely to access knowledge through a combination of business and intermediary sources and are less likely to have established formal collaborative or partnership agreements in the 3 years prior to the survey. We also find, however, that a higher proportion of US firms place a very high value on the connections they have with universities and are much more likely to commit resources to support such innovation related university interactions. A similar pattern of diffuse but weaker links characterise the supply of public sector financial assistance for innovation in our sample firms. UK firms are more likely to be in receipt of assistance, but receive far less per firm in absolute terms and relative to their R&D expenditures. It appears that the UK university–industry ecosystem is characterised by a greater width than quality of interaction.  相似文献
