The present article outlines the role of personal, social, and cultural identity in religiously and ethnically motivated terrorism. It is proposed that terrorism represents the confluence of a cultural identity strongly based in collectivism and in fundamentalist adherence to religious or cultural principles, a social identity based in sharp contrasts between one's own group and groups perceived as threats, and a foreclosed and authoritarian sense of personal identity or, less often, a diffused and aimless personal identity. Examples from religious-extremist and ethnic conflicts in which terrorism has been employed are used to illustrate the tenets advanced here. Recommendations for addressing and preventing the threat of terrorism are discussed.  相似文献

It is widely unclear as to whether start-up firms supported by publicly-initiated incubator initiatives have higher survival rates than comparable start-up firms that have not received support by such initiatives. This paper contributes to the underlying discussion by performing a large-scale matched-pairs analysis of the long-term survival of 371 incubator firms (after their graduation) from five German incubators and a control group of 371 comparable non-incubated firms. The analysis covers a 10-year time span. To account for the problem of selection bias, a non-parametric matching approach is applied to identify an appropriate control group. For neither of the five incubator locations, we find statistically significant higher survival probabilities for firms located in incubators compared to firms located outside those incubator organizations. For three incubator locations the analysis reveals statistically significant lower chances of survival for those start-ups receiving support by an incubator. The empirical results, therefore, raise some doubts regarding the impacts of incubation on long-term firm survival.  相似文献

Under current U.S. law, physicians may prescribe drugs and devices in situations not covered on the label approved by the Food and Drug Administration. Those supporting this system say that requiring FDA approval for off-label uses would unnecessarily impede the delivery of benefits to patients. Patients do benefit from off-label prescribing that is supported by sound scientific and medical evidence. In the absence of such evidence, however, off-label prescribing can expose patients to risky and ineffective treatments. The medical community and federal authorities should more actively promote patients' interests in receiving beneficial off-label treatments. To exercise responsible self-regulation, members of the medical community must determine whether available evidence justifies specific off-label uses and must promote information-gathering when the evidence is inadequate. Physicians should also discuss with patients the uncertainties accompanying off-label uses. Federal authorities should more closely monitor the effects of off-label prescribing and adopt other measures to reduce harm and enhance benefits produced by off-label prescribing.  相似文献

School-based health centers (SBHCs) have proliferated rapidly nation-wide and remain politically popular. This article explores the disconnect between the evidence and the discourse on SBHCs, drawing upon the authors' evaluation of SBHCs in Newark, New Jersey, and a critical assessment of the evaluative literature and public discourse on school clinics to argue that a number of important issues are being overlooked by both research and advocacy. These issues include variations in the health needs and health care resources of different communities and the questions of whether and how SBHCs can best integrate with existing resources to fill unmet local needs. Furthermore, despite the cautions of experts that third-party reimbursement (via traditional fee-for-service insurance or participation in health maintenance organizations) cannot cover clinic expenses and is difficult to obtain, pursuit of reimbursement continues to be a goal of some SBHC sponsors, helping to promote a clinic model that in some communities is very likely not to be the best way to address student needs or to build on clinic strengths. Discussion around SBHCs should focus on diagnosing specific community needs, identifying the best approach to meeting those needs, and seeking funding sources that match the work that needs to be done.  相似文献

Research examining the relationship between internalizing symptoms and antisocial behaviors has generally been cross-sectional in design. Thus, although extant data have substantiated a strong correlation between internalizing symptoms and antisocial behaviors, few studies have focused on describing the nature of the co-occurrence over time. This study examined the relation between growth in internalizing symptoms and longitudinal patterns of antisocial behavior in a sample of 283 inner-city males and their caregivers assessed as part of a longitudinal developmental risk study. Participants were assessed annually in four waves. Non-offenders and escalating offenders had lower levels of internalizing problems at wave 1 than did chronic minor and serious-chronic-violent offenders. Results revealed a developmental trend of decreasing internalizing problems across study years for most participants, as would be expected, with adolescents participating in serious, chronic, and violent patterns of antisocial behavior displaying greater internalizing problems than those participating in stable patterns of less serious or no antisocial behavior. Further, when there was escalation of seriousness and frequency of antisocial behavior, there also was increased internalizing problems relative to non-escalating juveniles. Results are discussed in the context of developmental psychopathology.

The following is an exchange concerning the concept of ‘illiberal moderates’ and its implications for a new global architecture as well as for a worldview that sees the evolution of a global core of shared values which favour domestic and international security, in sharp contrast to the ‘clash of civilizations’ thesis. The original statement was published in the Cambridge Review of International Affairs (Etzioni 2006). A more extensive treatment can be found in Part III of Security first: for a muscular, moral foreign policy (Etzioni 2007b), which examines texts of four religious and two secular belief systems as well as review of relevant public opinion polls and ‘traveller notes’. Here follows a brief summary of the main thesis, followed by comments from prominent scholars and Etzioni's response to these comments.  相似文献
