Underage drinking continues to be an important public health problem and a challenge to the substance abuse prevention field. Community-based interventions designed to more rigorously control underage access to alcohol through retailer education and greater enforcement of underage drinking laws have been advocated as potentially effective strategies to help address this problem, but studies designed to evaluate such interventions are sparse. To address this issue we conducted a randomized trial involving 36 communities to test the combined effectiveness of five interrelated intervention components designed to reduce underage access to alcohol. The intervention was found to be effective in reducing the likelihood that retail clerks would sell alcohol to underage-looking buyers, but did not reduce underage drinking or the perceived availability of alcohol among high school students. Post hoc analyses, however, revealed significant associations between the level of underage drinking law enforcement in the intervention communities and reductions in both 30-day use of alcohol and binge drinking. The findings highlight the difficulty in reducing youth drinking even when efforts to curtail retail access are successful. Study findings also suggest that high intensity implementation of underage drinking law enforcement can reduce underage drinking. Any such effects of enhanced enforcement on underage drinking appear to be more directly attributable to an increase in perceived likelihood of enforcement and the resultant perceived inconveniences and/or sanctions to potential drinkers, than to a reduction in access to alcohol per se.  相似文献

ABSTRACT

For over two decades, despite the downward crime trend, the American public has persisted in believing crime is on the rise. Cultivation theory holds that the media is responsible for the public’s crime trend perceptions. Previous cultivation studies heavily rely on cross-sectional data, which may lead to spurious conclusions due to reverse causation and omitted variable bias. This study aims to address these issues by utilizing longitudinal analyses. Drawing on three waves of the 2008–2009 American National Election Survey, we test the cultivation hypothesis using traditional OLS, OLS with lagged crime trend perceptions, fixed effects, and dynamic panel models. Newspaper and TV news consumption are related to crime trend perceptions in traditional OLS models. In other models, media consumption is not related to crime trend perceptions. The results do not support the cultivation hypothesis. It is likely that the cultivation effect of media has been overstated in the previous cross-sectional research.  相似文献

While humans rely on vision during navigation, they are also competent at navigating non-visually. However, non-visual navigation over large distances is not very accurate and can accumulate error. Currently, it is unclear whether this accumulation of error is due to the visual estimate of the distance or to the locomotor production of the distance. In a series of experiments, using a blindfolded walking test, we examine whether enhancing the visual estimate of the distance to a previously seen target, through environmental enrichment, visual imagery, or repeated exposure would improve the accuracy of blindfold navigation across different distances. We also attempt to decrease the visual estimate in order to see if the opposite effect would occur. Our results would indicate that manipulation of the static visual distance estimate did not change the navigation accuracy to any great extent. The only condition that improved accuracy was repeated exposure to the environment through practice. These results suggest that error observed during blindfold navigation may be due to the locomotor production of the distance, rather than the visual process.  相似文献

In this study we examined the interplay between appetitive (approach) and defensive (avoid) responses in spoken word recognition. Ninety-two right-handed participants (half women) took part in an auditory lexical decision experiment in which speech was presented to only one ear. The danger and usefulness of the word referents interacted in predicting RTs, as in previous (binaural) studies with poorer control of psycholinguistic covariates. Specifically, higher danger ratings were associated with faster RTs for words rated low on usefulness; but higher danger ratings were associated with slower RTs for words rated high on usefulness. In addition to this primary finding, men showed more lateralised performance, as indicated by significant interactions of sex and ear of presentation with word frequency, and with the animacy of the word referents. For both sexes, word frequency had a stronger effect on accuracy for speech presented to the right ear. Finally, men's but not women's RTs were related to the danger dimension. This last finding provides an intriguing avenue for future research in the area of sex differences and emotion.  相似文献

Abstract

This article considers an assortment of issues regarding research into reading problems of the elderly. It is based on research results that grew out of a two‐year federal grant from the National Institute of Aging. The discussion includes an examination of demands placed on senior citizens’ reading skills by materials disseminated through agencies at the federal, state, and local levels.  相似文献

Abstract

This study considered relationships between the intensity and directional aspects of competitive state anxiety as measured by the modified Competitive Sport Anxiety Inventory-2(D) (Jones & Swain, 1992 Jones, G. and Swain, A. B. J. 1992. Intensity and direction as dimensions of competitive state anxiety and relationships with competitiveness. Perceptual and Motor Skills, 74: 467472. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) in a sample of 12 experienced male golfers. Anxiety and performance scores from identical putting tasks performed under three different anxiety-manipulated competitive conditions were used to assess both the predictions of Multidimensional Anxiety Theory (MAT; Martens et al., 1990 Martens, R., Burton, D., Vealey, R., Bump, L. and Smith, D. 1990. “The development of the Competitive State Anxiety Inventory-2 (CSAI-2)”. In Competitive anxiety in sport, Edited by: Martens, R., Vealey, R. S. and Burton, D. 117190. Champaign, IL: Human Kinetics.  [Google Scholar]) and the relative value of intensity and direction in explaining performance variance. A within-subjects regression analysis of the intra-individual data showed partial support for the three MAT hypotheses. Cognitive anxiety intensity demonstrated a negative linear relationship with performance, somatic anxiety intensity showed a curvilinear relationship with performance, and self-confidence intensity revealed a positive linear relation. Cognitive directional anxiety illustrated a positive linear relationship with putting performance. Multiple regression analyses indicated that direction (42% of variance) was a better predictor of performance than intensity (22%)  相似文献

Second language (L2) instruction programs often ask learners to repeat aloud words spoken by a native speaker. However, recent research on retrieval practice has suggested that imitating native pronunciation might be less effective than drill instruction, wherein the learner is required to produce the L2 words from memory (and given feedback). We contrasted the effectiveness of imitation and retrieval practice drills on learning L2 spoken vocabulary. Learners viewed pictures of objects and heard their names; in the imitation condition, they heard and then repeated aloud each name, whereas in the retrieval practice condition, they tried to produce the name before hearing it. On a final test administered either immediately after training (Exp. 1) or after a 2-day delay (Exp. 2), retrieval practice produced better comprehension of the L2 words, better ability to produce the L2 words, and no loss of pronunciation quality.  相似文献

This article argues that discourse used to define and understand Israel by prominent American Christian Zionists is a discourse of national idealisation. Drawing on Durkheim's (2008 Durkheim, Emile. 2008. The Elementary Forms of Religious Life, Oxford: Oxford University Press. Translated by C. Cosman [Google Scholar]) notion of symbols as sources of social solidarity, I argue that this imagined Israel reflects conservative social and military values that are shared among Christian Zionists and their supporters – values which many in this broad category see the United States failing to uphold. Following this, I show how one of America's most prominent pastors – John Hagee – and his organisation – Christians United for Israel – have taken on the role of a contemporary Jeremiah, criticising the American government for not adequately supporting Israel. This article concludes by considering how Christian Zionists are calling America to renew and align itself with God by ‘blessing’ Israel, and acting like Israel.  相似文献

The starting point of this paper will be studies that view popular culture as religion. First, I examine a selection of recent works that argue certain popular culture communities—namely, music subcultures, sports, and television and celebrity fandoms—look like, act like, and indeed are religions for participants. Methodologically, the studies under examination proceed by starting with a definition of religion and then looking for parallels between the pop culture fandom and the definition. I suggest that popular culture as religion scholarship is at best creative, always problematic, and tends toward what Samuel calls ‘parallelomania’. In the second part of the paper, I use the studies under examination, as well as original research, to argue that contemporary fandoms are better understood as late modern ‘projects of the self’, affiliational choices that act to establish self-identity and community in a time period when these things are not given, but reflexively made and remade.  相似文献

The Bender-Gestalt was given following the Canter Background Interference Procedure (BIP) to 40 schizophrenics divided into paranoid-nonparanoid and process-reactive sub-categories. Nonparanoids performed significantly poorer under BIP conditions than under standard procedure. Paranoids performed equally well under both conditions. Comparison with Canter's brain-damaged Ss indicated that process nonparanoid schizophrenics resemble brain-damaged Ss using this procedure.  相似文献
