The tragic events in Aurora, CO and Newtown, CT have renewed public perception of mentally persons as ‘dangerous’ and ‘criminal.’ Unfortunately, this perception is based more on conjecture and fear than research. The following essay takes stock of the empirical research on mental illness and criminal behavior. Three noteworthy trends emerge from this literature. First, the prevalence of mental illness is substantially higher among individuals who have come in contact with the criminal justice system relative to the general population. Second, individuals with psychotic and externalizing behavioral disorders, particularly those who also abuse drugs and alcohol, tend to engage in higher levels of violence than individuals with other forms of mental illness. Third, mental illness does not determine whether someone will break the law; rather, it is but one of many criminogenic risk factors that interact in complex ways to influence individual behavior.  相似文献

People differ in their comfort with tampering with the natural world. Although some see altering nature as a sign of human progress, others see it as dangerous or hubristic. Across four studies, we investigate discomfort with tampering with the natural world. To do so, we develop the Aversion to Tampering with Nature (ATN) Scale, a short scale that is the first to directly measure this discomfort. We identify six activities that people believe tamper with nature (geoengineering, genetically modified organisms, pesticides, cloning, gene therapy, and nanoparticles) and show that ATN scores are associated with opposition to these activities. Furthermore, the ATN Scale predicts actual behavior: donations to an anti-tampering cause. We demonstrate that ATN is related to previously identified constructs including trust in technology, naturalness bias, purity values, disgust sensitivity, aversion to playing God, and environmental beliefs and values. By illuminating who is concerned about tampering with nature and what predicts these beliefs, the ATN Scale provides opportunities to better understand public opposition to technological innovations, consumer preferences for “natural” products, and strategies for science communication.  相似文献

Cue-reactivity has received increased attention in addiction research, though not for gambling in particular. We examined cue reactivity in 18 problem gamblers by accompanying them to a gaming casino and measuring their subjective urge to gamble over a 1-h period. Half of the sample was additionally exposed to a gambling-specific negative mood induction (NMI) manipulation via guided imagery. Overall, about two-thirds of the sample reported moderate to high-gambling urges during the casino exposure. Additionally, the NMI reduced cue-reactivity. Finally, gambling urges in both groups decreased over the course of the exposure sessions. These findings suggest that a majority of problem gamblers experience the urge to gamble when exposed to gambling cues and that the intensity of these urges decrease with time, especially in the presence of a gambling-relevant NMI. Cue exposure should be studied further as a potential tool in the treatment of problem gambling.  相似文献

Studies regarding the effectiveness of homework assignments in cognitive‐behavioral treatments have demonstrated mixed results. This study investigated predictors of compliance with homework recommendations and the time‐varying relationship of recommendation completion with treatment response in a brief couples' intervention (= 108). More satisfied couples and couples with more motivation to change completed more recommendations, whereas couples with children completed fewer. The association between recommendation completion and treatment response varied with the passage of time, with the strongest effect observed 6 months after the intervention, but no discernible differences at 1 year postintervention. Couples that completed more recommendations experienced more rapid treatment gains, but even those couples doing substantially fewer recommendations ultimately realized equivalent treatment effects, although they progressed more slowly. Implications are discussed.  相似文献

In contrast to conventional models of positively “becoming” an identity through social interaction, this article explores the inverse, negational process of “non‐becoming,” whereby actors start but do not continue along an identity career trajectory. Through cumulative attrition, interactions and encounters at key moments create an overall pattern of non‐progression. Using asexuality as an example, we identify three main trajectory stages of non‐awareness, communicative negation and non‐consolidation, each involving interactional contingencies. With a wider applicability to other repudiated identities, this model shows how even negational symbolic social objects (non‐issues, non‐events, and non‐identities) are constituted through social interaction.  相似文献

Virtual worlds, such as World of Warcraft and Second Life, have seen remarkable mainstream uptake in the last decade. Such environments have grown from hosting niche interest groups to providing sites for leisure, business and education for tens of millions of Internet users. Concurrently, a multi-disciplinary research field exploring the application of such spaces has emerged. This article examines in detail one data collection practice – observation in virtual worlds – that has been applied extensively, but without extensive methodological discussion. By revisiting and extending earlier work on this topic, the article presents four key considerations for those conducting observational research in virtual worlds: defining and delimiting field sites, discerning attention, charting actions and attributing intention. It is concluded that researchers must both ward against flawed assumptions about virtual world observation and consider multi-method strategies to overcome limitations in observational data.  相似文献

‘Professional boundaries’ set limits on appropriate behaviours in the relationship between the service users and practitioners. The professional literature often assumes boundaries are maintained by the practitioners, occupational bodies, or organisational policy. However in youth work this is under-researched. An ethnographic study of four youth clubs in the North East of England into ethical practice revealed that young people were surprisingly adept at maintaining boundaries with the youth workers. These boundaries were negotiated and maintained through the young people's use of space, their willingness to interact with the workers, the way they shared information with the workers, and their inclusion of youth workers into their social networking. Young people also showed a sophisticated awareness of the organisational boundaries youth workers were operating within, and often cooperated in maintaining them with the worker. The article concludes by arguing youth workers should take seriously young people's ability and willingness to set and work within boundaries, and see their negotiation and maintenance as a mutual endeavour. However, this may provide a challenge to organisations with rigid policy-defined boundaries.  相似文献
