The goal of this study was to assess the feasibility and effectiveness of two interventions aimed at reducing alcohol-related risks at community festivals--a training program for festival planners and a community organizing campaign. We randomly selected four festivals for each intervention and had 24 comparison festivals. Our assessment included process evaluation to track and evaluate types of alcohol policies resulting from each of the interventions, pre and post telephone surveys of key festival planners and law enforcement agencies, and pre and post pseudo-underage and pseudo-intoxicated purchase attempts. Analyses showed that both interventions were feasible and were successful in influencing adoption of written policies and improving alcohol-related practices. However, neither intervention appeared to decrease propensity for illegal alcohol sales at these events, likely due, in part, to the short time frame of the interventions. Future research should assess effects of the interventions on alcohol-related problems and effects of enforcement interventions.  相似文献

Analysis of the human sex ratio by using overdispersion models   总被引:2,自引:1,他引:1  
For study of the human sex ratio, one of the most important data sets was collected in Saxony in the 19th century by Geissler. The data contain the sizes of families, with the sex of all children, at the time of registration of the birth of a child. These data are reanalysed to determine how the probability for each sex changes with family size. Three models for overdispersion are fitted: the beta–binomial model of Skellam, the 'multiplicative' binomial model of Altham and the double-binomial model of Efron. For each distribution, both the probability and the dispersion parameters are allowed to vary simultaneously with family size according to two separate regression equations. A finite mixture model is also fitted. The models are fitted using non-linear Poisson regression. They are compared using direct likelihood methods based on the Akaike information criterion. The multiplicative and beta–binomial models provide similar fits, substantially better than that of the double-binomial model. All models show that both the probability that the child is a boy and the dispersion are greater in larger families. There is also some indication that a point probability mass is needed for families containing children uniquely of one sex.  相似文献

The current practice in many schools of educating children on how to keep themselves safe from abuse and abduction tends to concentrate on teaching them about stranger-danger and how to avoid it. However, recent research suggests that children may have difficulty in understanding the stranger-danger message (Mayes, Gillies and Warden, 1990). The present study examines 6-, 8- and 10-year-old children's understanding of the concepts of ‘stranger’ and ‘danger’ by analysing their verbal responses to videotaped sequences depicting child encounters with a variety of known and unknown male adults. Results indicate that, although there is some evidence of developing wariness, children at ages 8 and even 10 years appear still to be vulnerable to approaches made by strangers. © 1997 by John Wiley & Sons, Ltd.  相似文献

Previous research has demonstrated that safety climate is a robust predictor of safety-related outcomes. However, there is little consensus about the optimal strategy to measure safety climate. One of the main issues has been whether safety climate measures should be universal or industry-specific. As such, this study was designed to examine the criterion-related validity of universal and industry-specific safety climate measures by conducting a meta-analytic comparison of their relationships with a variety of safety-related outcomes (i.e. safety behaviour, risk perceptions, accidents and injuries, and other adverse events). With 120 independent samples (N?=?81,213), we found that the industry-specific safety climate measures displayed better predictive power when predicting safety behaviour and risk perceptions than the universal safety climate measures. On the other hand, the universal safety climate measures displayed better predictive power when predicting other adverse events (but not accidents and injuries) than the industry-specific safety climate measures. We discuss these findings in light of the intended use of organisational safety climate surveys.  相似文献

Public relations practitioners face workplace challenges as they cultivate public relationships, resolve conflicts, and manage crises. Odds of adversities may be high in this role, requiring practitioners to be resilient. This qualitative study explores workplace adversities in public relations from a practitioners’ perspective, and examines how they enact resilience. By asking current practitioners about their lived experiences, we found workplace adversities occurred on multiple levels and ranged from mundane to life-altering events. Patterns of resilience were, metaphorically, bouncing forward, bouncing up, bouncing back, and bouncing around. This study contributes to public relations and resilience scholarship by (1) uncovering workplace adversities and resilience enactment in public relations, therefore connecting practice with scholarship, (2) extending the “bounce back” metaphor in the resilience literature, therefore making resilience more inclusive, and (3) exploring the connections of multi-level resilience, and suggesting the complex and negotiated nature of resilience among individuals embedded in collectives.  相似文献

There is burgeoning literature on cities that host major cultural events. However, there is surprisingly very little empirical research focusing specifically on young people and cities of culture, so we have limited knowledge in terms of how young people actually experience and interpret cultural events. Given this, we offer an important and timely contribution to such debates. Our spatial focus is Derry/Londonderry (D/L) in Northern Ireland. During 2013 D/L was the UK’s inaugural City of Culture (CoC). The bid document and legacy plans for CoC stated that young people would be ‘cultural assets’ during 2013 and the ‘ultimate beneficiaries’ of the CoC legacy [Derry City Council 2010. Cracking the Code. City of Culture 2013. Derry: Derry City Council, 2013a. Our Legacy Promise. Building on the Success of 2013. Derry: Derry City Council, 2013b. Legacy Plan 2013–2023. Derry: Derry City Council]. This paper unpacks and analyses the extent to which young people in D/L related to and engaged with CoC and, arguably more importantly, how CoC affected their plans and aspirations for the future. Our research problematises the claim that young people were the ‘ultimate beneficiaries’ of CoC; most strikingly, it shows that young people, despite offering very positive views, both expect and desire to live in cities other than D/L. As such, the debilitating long-standing trend of economic migration of young people will continue raising important issues for local stakeholders.  相似文献

Terms like “binge-watching” and the “showhole” suggest a relationship between binge-watching and emotional health. This study sought to understand the relationship between binge-watching, unhealthy emotional traits, and regular emotional states such as sadness. The study found that emotional states experienced after binge-watching had implications for entertainment gratifications. However, the study did not find a conclusive connection between binge-watching and unhealthy emotional traits.  相似文献

Addictive disorders, such as pathological gambling and alcohol use disorders, frequently co-occur at greater than chance levels. Substantive questions stem from this comorbidity regarding the extent to which shared variance between gambling and alcohol use reflects a psychological core of addictive tendencies, and whether this differs as a function of gender. The aims of this study were to differentiate both common and unique variance in alcohol and gambling problems in a bifactor model, examine measurement invariance of this model by gender, and identify substantive correlates of the final bifactor model. Undergraduates (N = 4475) from a large northwestern university completed an online screening questionnaire which included demographics, quantity of money lost and won when gambling, the South Oaks Gambling Screen, the AUDIT, gambling motives, drinking motives, personality, and the Brief Symptom Inventory. Results suggest that the bifactor model fit the data well in the full sample. Although the data suggest configural invariance across gender, factor loadings could not be constrained to be equal between men and women. As such, general and specific factors were examined separately by gender with a more intensive subsample of females and males (n = 264). Correlations with motivational tendencies, personality traits, and mental health symptoms indicated support for the validity of the bifactor model, as well as gender-specific patterns of association. Results suggest informative distinctions between shared and unique attributes related to problematic drinking and gambling.  相似文献
