Abstract Background: Young adults remain the earliest legal target for the tobacco industry. Against this, the existence of smoking policies would appear to offer some protection to students on campus. However, little research has been conducted into the outcomes of such policies from a student perspective. Methods: The authors conducted 8 focus groups at 4 selected Canadian undergraduate campuses to investigate student perceptions and behaviors resulting from campus smoking policies. Results: Results indicated that student smoking behaviors are minimally impacted by campus smoking policies due to seriously compromised implementation and enforcement. Conclusions: These findings imply that the presence of campus smoking policies and claims of “smoke-free” campuses should not be misinterpreted as achievement and without renewed focus and adequate tobacco control infrastructure, it will remain possible for young adults to initiate and maintain tobacco smoking on campus. 相似文献

High levels of worldwide migration paired with increasingly negative attitudes toward immigrants and immigration in host countries indicate that it is crucial to gain an understanding of the bases of these attitudes. This article discusses one determinant of negative attitudes toward immigrants and immigration: perceived competition for resources. We present our instrumental model of group conflict, which suggests that competition for resources, and attempts to remove this competition, are important determinants of intergroup attitudes and behavior. We then review relevant research on perceived competition and attitudes toward immigrants and immigration. We conclude by discussing the implications of this research for attempts to alleviate tension between immigrants and members of host populations, and for our more general model of group conflict. 相似文献

It has been suggested that infants respond preferentially to infant‐directed speech because their auditory sensitivity to sounds with extensive frequency modulation (FM) is better than their sensitivity to less modulated sounds. In this experiment, auditory thresholds for FM tones and for unmodulated, or pure, tones in a background of noise were measured for 4‐month‐old infants using a conditioned response procedure. The FM tones swept from 150 to 275 Hz or from 150 to 550 Hz. The frequency of the pure tone was either 275 or 550 Hz. The results showed that infants were slightly, but significantly, more sensitive to the sounds that included 550 Hz than they were to the lower frequency sounds, whether or not the sound was frequency modulated. It appears that infants could be somewhat more sensitive to infant‐directed than to adult‐directed speech, not because of FM per se, but because the fundamental frequency excursions in infant‐directed speech extend into a higher frequency range than those in adult‐directed speech. 相似文献

This article discusses general issues and concerns relative to the adaptation of paper-pencil assessment instruments to computerized formats. The computerized form of the Self-Directed Search is described and evaluated. Strengths and weaknesses of the SDS-CV are presented and recommendations regarding its use are discussed. In that additional research is needed regarding the reliability and validity of scores attained on the computerized SDS, we concluded that information from this version of the instrument should be interpreted cautiously. The computerized SDS, however, has the potential of becoming a useful instrument in the career counseling field. 相似文献

Links between religion and prejudice have been interpreted to suggest that religion can both reduce and exacerbate prejudice. Here, the analysis of religion as a meaning system illuminates how religion can affect intergroup attitudes. Traditional psychological perspectives on religion and prejudice are summarized, followed by a discussion of religion and prejudice in cross-cultural and cross-religious contexts, involving varying target groups. Next, we explore possible explanatory mechanisms by proposing how four levels of meaning associated with religion—cognitive, motivational, societal, and intergroup—may both promote and attenuate prejudice. Finally, additional factors that might facilitate the paradoxical coexistence of religious egalitarian intentions with prejudiced attitudes are considered, and we speculate about the potential for religious groups to reduce prejudice within their adherents. 相似文献

This article suggests an alternative to the ratio estimator for estimating the total size of a subdomain of a population. The application that served as the genesis for this work is from auditing. The problem is to estimate the total of sales transactions that are not tax exempt from an audit sample of the population of nontaxed sales transactions. A superpopulation approach, which models the unit's probability of belonging to the subdomain as a function of its size, leads to a family of estimators. The simplest member of this famiiy is one in which that function is specified to be a constant. The optimal estimator for this model performs markedly better than the ratio estimator when the assumption is true and often performs better when it is not, though in that case it is biased. Stratification is shown to reduce this bias and at the same time make the ratio estimator more similar to the optimal estimator. A simulation experiment shows that the theoretical advantages hold in a real audit population. 相似文献

One ultimate test of the material value of identification in an organizational context is whether it relates to productivity. In this rare study of a business team in a global consumer goods company, we demonstrate a sales benefit of organizational identification when correcting for systematic between‐unit differences in sales. Findings also question the theoretical and practical meaning of ‘proximity’ in accounting for salience variations in identification – the best predictor of sales was the degree of identification with the superordinate business unit. Findings shed light on the scientific as well as managerial and business utility of the organizational identity concept. 相似文献

This study proves once again that too many press releases are poorly written and over-written, with long sentences and paragraphs, and poor syntax as well as weak and passive construction. In their use of press releases, journalists almost always have to make them simpler, shorter, easier to read, and less passive.The authors conclude that success in writing of press releases requires brevity and simplicity, shorter paragraphs, sentences, and words, and the elimination of the passive voice.Timothy Walters is an assistant professor of communication at Stephen F. Austin State University in Nacogdoches, TX. Lynne Walters is associate professor of journalism and Douglas Starr professor of journalism, both at Texas A&M University, College Station. Lynne Walters is currently a Fulbright professor at the American Journalism Center in Budapest, where her husband Timothy is also on a one-year appointment as a visiting professor. 相似文献

La forme que prend le ménage en milieu rural semble dépendre de facteurs structuaux tel l'accès aux ressources sans toutefois en être déterminée. Contrairement aux analyses qui soulignent seulement la présence d'un concensus au sein du ménage, nous considérons le ménage rural comme une unité politique qui implique des négotiations quotidiennes entre ses membres. Le concept d'hégémonie du ménage' est un outil analytique utile permettant d'aller au-delà des catégories 'conflit' et 'consensus' pour caractériser les dynamiques internes du ménage rural. Cette perspective est développée à l'intérieur d'une analyse de la dynamique entre les sexes dans le ménages ruraux de la côte de l'Équateur. Cet essai identifie certaines implications de cette approche en ce qui concerne les femmes et le développement.
Structural criteria such as access to land may condition the form the rural household takes but they do not determine it. It is suggested here, in contrast to analyses which emphasize household consensus, that we appreciate the farm household as a political unit involving daily negotiations between household members. The concept of 'household hegemony' is introduced as a helpful analytical tool which goes beyond conflict versus consensus dynamics. This approach is developed through a consideration of the gender dynamics within rural households in coastal Ecuador. Specific implications for women and development issues are considered. 相似文献
