In 2012, the SAMHSA‐funded National Suicide Prevention Lifeline (Lifeline) completed implementation of the first national Policy for Helping Callers at Imminent Risk of Suicide across its network of crisis centers. The policy sought to: (1) provide a clear definition of imminent risk; (2) reflect the state of evidence, field experience, and promising practices related to reducing imminent risk through hotline interventions; and (3) provide a uniform policy and approach that could be applied across crisis center settings. The resulting policy established three essential principles: active engagement, active rescue, and collaboration between crisis and emergency services. A sample of the research and rationale that underpinned the development of this policy is provided here. In addition, policy implementation, challenges and successes, and implications for interventions to help Lifeline callers at imminent risk of suicide are detailed.  相似文献

This paper contributes to the current academic debate on the nature of embodied, intentional consciousness, specifically the attempt to inaugurate a rapprochement between phenomenological existentialism and critical theory. This is accomplished through a critical comparison of the concepts of negative experience and nonidentity in Theodor Adorno's negative dialectics and Jean‐Paul Sartre's early phenomenology. By comparing how each engages with Hegel, I suggest that Sartre offers a broad, anthropological account of negative experience and nonidentity helpful to critical theorists but that there remains a critical deficit which Adorno's more restricted—and political—sense of nonidentity remedies. Sartre's anthropological portrayal of ‘persistent negation’ worries Adorno but I suggest that it can be understood as a pragmatic presupposition for problem‐solving rather than as a transcendental condition of experience.  相似文献

Facial appearances can powerfully influence adults' trust behaviour, despite limited evidence that these cues constitute honest signals of trustworthiness. It is not clear, however, whether the same is also true for children. The current study investigated whether, like adults, 5‐year‐olds and 10‐year‐olds are more likely to place their trust in partners that look trustworthy than those that look untrustworthy. A second, closely related question was whether children also explicitly value the information from face cues when making trust decisions. We investigated these questions using Token Quest: an economic trust game that gave participants the opportunity to make investments with a series of partners who might (or might not) repay their trust with large returns. These interactions occurred under different conditions, including one in which participants were shown the face of each partner and another in which they could ‘purchase’ access to faces with a portion of their investment capital. Results indicated that, like adults, 10‐year‐old children selectively placed their trust in those partners they perceived as looking trustworthy and many were willing to ‘pay’ to purchase access to these face cues during the trust game. We observed a similar profile of trust behaviour in 5‐year‐olds, with no significant group difference in the impact of face cues on behaviour across the three age groups. Together, these findings indicate that the influence of face cues on trust behaviour emerges early, and highlight a capacity for sophisticated social cognition in young children.  相似文献

This project evaluates the impact of the National Science Foundation's (NSF) policy to promote education in the responsible conduct of research (RCR). To determine whether this policy resulted in meaningful RCR educational experiences, our study examined the instructional plans developed by individual universities in response to the mandate. Using a sample of 108 U.S. institutions classified as Carnegie “very high research activity”, we analyzed all publicly available NSF RCR training plans in light of the consensus best practices in RCR education that were known at the time the policy was implemented. We found that fewer than half of universities developed plans that incorporated at least some of the best practices. More specifically, only 31% of universities had content and requirements that differed by career stage, only 1% of universities had content and requirements that differed by discipline; and only 18% of universities required some face-to-face engagement from all classes of trainees. Indeed, some schools simply provided hand-outs to their undergraduate students. Most universities (82%) had plans that could be satisfied with online programs such as the Collaborative Institutional Training Initiative's RCR modules. The NSF policy requires universities to develop RCR training plans, but provides no guidelines or requirements for the format, scope, content, duration, or frequency of the training, and does not hold universities accountable for their training plans. Our study shows that this vaguely worded policy, and lack of accountability, has not produced meaningful educational experiences for most of the undergraduate students, graduate students, and post-doctoral trainees funded by the NSF.  相似文献

Studies of transmission biases in social learning have greatly informed our understanding of how behaviour patterns may diffuse through animal populations, yet within-species inter-individual variation in social information use has received little attention and remains poorly understood. We have addressed this question by examining individual performances across multiple experiments with the same population of primates. We compiled a dataset spanning 16 social learning studies (26 experimental conditions) carried out at the same study site over a 12-year period, incorporating a total of 167 chimpanzees. We applied a binary scoring system to code each participant’s performance in each study according to whether they demonstrated evidence of using social information from conspecifics to solve the experimental task or not (Social Information Score—‘SIS’). Bayesian binomial mixed effects models were then used to estimate the extent to which individual differences influenced SIS, together with any effects of sex, rearing history, age, prior involvement in research and task type on SIS. An estimate of repeatability found that approximately half of the variance in SIS was accounted for by individual identity, indicating that individual differences play a critical role in the social learning behaviour of chimpanzees. According to the model that best fit the data, females were, depending on their rearing history, 15–24% more likely to use social information to solve experimental tasks than males. However, there was no strong evidence of an effect of age or research experience, and pedigree records indicated that SIS was not a strongly heritable trait. Our study offers a novel, transferable method for the study of individual differences in social learning.  相似文献

Individuals with defensive self-esteem score low on implicit measures of self-esteem (ISE) and high on explicit measures of self-esteem (ESE). Although there is some evidence about the consequences of defensive self-esteem, much of it is indirect and open to alternative explanations. Here, we offer direct and novel evidence regarding the implications of defensive self-esteem. Using a standard visual attention paradigm, Study 1 revealed that defensive self-esteem is associated with enhanced attention to defensiveness-related words. Building upon these results, Study 2 found that defensive self-esteem individuals reported particularly strong attitudes, across different operationalizations of attitude strength as well as different attitude objects. Study 3 examined the sensitivity of defensive self-esteem individuals to self-affirmation effects. The results revealed that self-affirmation was particularly effective for defensive self-esteem individuals in reducing actual-ideal self-discrepancies. Overall, the results provide novel and firm evidence that the combination of simultaneously low ISE and high ESE elicits defensiveness.  相似文献

Do people perceive themselves as becoming more attractive across time? The present studies investigated whether individuals (a) judge their previous self as physically less attractive than their current self and (b) judge their future self to be physically more attractive than their current self. The studies also investigated when temporal biasing of attractiveness is most likely to occur. In Study 1, students rated their present and past attractiveness. The results revealed that participants' ratings of past attractiveness were lower than current ratings, but only among individuals for whom attractiveness was important to their self‐concept. In Study 2, participants rated their present attractiveness and their expected attractiveness in 5 years. The results revealed that ratings of future attractiveness were higher than current ratings, but only among individuals who frequently engage in social comparisons. The implications of the results are discussed with respect to self‐appraisals of attractiveness and psychological well‐being. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

Means‐end chain (MEC) theory proposes that consumer motivation can only be understood in terms of the hierarchical linkages between attributes, consequences and values. Other researchers have suggested a much more immediate impact of values on motivation. Seeking to explain these conflicting views, this research suggests and empirically tests the proposition that the role of values in consumer motivation differs by product type and also tests that the linkages are not affected by individual differences in the need for cognition. A sample of 191 consumers indicated their motivation to consume utilitarian and non‐utilitarian products using an adapted association pattern matrix technique. Responses were analysed using mixed‐design ANOVAs with planned comparisons. Results indicate significant differences related to product type in the role of values in consumer motivation. Limitations, implications for MEC theory and future research are discussed. Copyright © 2004 Henry Stewart Publications Ltd.  相似文献
