Abstract Objectives: This study assessed college counselors’ anticipatory guidance on firearms for student clients. Participants: The membership of the Association for University and College Counseling Center Directors was used to identify a national random sample of counseling centers (n = 361). One counselor from each center was selected to survey. Methods: In the winter of 2008, a 3-wave mailing procedure was used to maximize the response rate. Completed surveys served as consent (as approved by the University Human Subjects Committee). Results: A total of 213 counselors (59%) responded. They were unlikely to provide anticipatory guidance (6%), chart/keep records on client ownership/access to firearms (17%), or to counsel the majority of clients from various diagnostic categories on firearms. Conclusions: University personnel are likely to refer students with suspected mental health problems to university counseling centers. The findings indicate that few counseling centers will address firearm issues with students. 相似文献

Reduced-rank regression models proposed by Anderson [1951. Estimating linear restrictions on regression coefficients for multivariate normal distributions. Ann. Math. Statist. 22, 327–351] have been used in various applications in social and natural sciences. In this paper we combine the features of these models with another popular, seemingly unrelated regression model proposed by Zellner [1962. An efficient method of estimating seemingly unrelated regressions and tests for aggregation bias. J. Amer. Statist. Assoc. 57, 348–368]. In addition to estimation and inference aspects of the new model, we also discuss an application in the area of marketing. 相似文献

The literature in economic psychology and quality-of-life studies alludes to a negative relationship between materialism and life satisfaction. In contrast, the macroeconomic literature implies a positive relationship between material consumption and economic growth. That is, materialism may be both good and bad. We develop a model that reconciles these two contrasting viewpoints by asserting that materialism may lead to life dissatisfaction when materialistic people evaluate their standard of living using fantasy-based expectations (e.g., ideal expectations), which increases the likelihood that they would evaluate their standard of living negatively. In turn, dissatisfaction with standard of living increases the likelihood that they would evaluate their life negatively. However, materialistic people who evaluate their standard of living using reality-based expectations (e.g., ability expectations) are likely to feel more economically motivated than their non-materialistic counterparts, and this economic motivation is likely to contribute significantly and positively to life satisfaction. Survey data were collected from seven major cities each in a different country (Australia, Bosnia/Herzegovina, Germany, Egypt, Korea, Turkey, and the USA) using a probability sample (cluster sampling method involving income stratification). The results provide support for the model. The economic public policy implications concerning how people evaluate their standard of living using ability-based expectations are discussed in the context of the ideals of meritocracy. 相似文献

Abstract A recent wave of research promotes the idea that anonymity or deindividuation precipitates collective behavior. Specifically, anonymous individuals are more likely to participate in collective behavior events than people among friends and acquaintances. To reconsider this recent resurgence of a more contemporary contagion theory, we replicate and expand upon Aveni's (1977) study of crowd behavior. Our survey data of crowd and collective behavior participants show that anonymity actually hinders the emergence of collective behavior. Rather, collective behavior participants are more likely to be in small groups rather than isolated individuals. Our data do suggest that one form of anonymity (i.e., anonymity from formal agents of social control) can facilitate the emergence of collective behavior. 相似文献

Sample size re-estimation without unblinding for normally distributed outcomes with unknown variance
Monitoring clinical trials in nonfatal diseases where ethical considerations do not dictate early termination upon demonstration of efficacy often requires examining the interim findings to assure that the protocol-specified sample size will provide sufficient power against the null hypothesis when the alternative hypothesis is true. The sample size may be increased, if necessary to assure adequate power. This paper presents a new method for carrying out such interim power evaluations for observations from normal distributions without unblinding the treatment assignments or discernably affecting the Type 1 error rate. Simulation studies confirm the expected performance of the method. 相似文献

ABSTRACT The past twenty years have seen a surge of resources for and public attention devoted to civic participation opportunities for older adults in the United States. At the same time, technology has transformed the way information related to political and social issues is spread and shared. As more older adults migrate to using a wider range of communication tools and the internet, technology-mediated forms of engagement represent a new way for the oldest old to participate in society. In this study, a panel of adults ages 85 and older was surveyed to understand their experiences engaging with political and social issues. Responses to a questionnaire (N = 24) and focus groups (n = 22) indicate the oldest old are interested in social and political issues, and there are opportunities for technology to facilitate the oldest olds’ civic and political action. This study identifies roles social workers may play in helping the oldest old engage with social and political issues in their communities. 相似文献
