Short-Term Prospective Effects of Impulsivity on Binge Drinking: Mediation by Positive and Negative Drinking Consequences

Abstract. Objective: Although the association of impulsivity with diverse alcohol outcomes has been documented, the mechanisms by which impulsivity predicts drinking over time remain to be fully characterized. The authors examined whether positive drinking consequences, but not negative drinking consequences, mediated the association between impulsivity and subsequent binge drinking, over and above prior binge drinking. Participants: Participants were 171 college students. Methods: Participants completed 2 online surveys with an average interval of 68 days between assessments at Time 1 (September to October 2012) and Time 2 (November to December 2012). Results: Path analysis showed that, among 5 facets of impulsivity, the effect of sensation seeking on subsequent binge drinking was completely mediated by prior positive consequences. No mediating effects of negative consequences were found. Conclusions: Prior experience of positive drinking consequences may serve as one of the risk pathways by which sensation seeking shapes binge drinking over time. Personalized intervention strategies may utilize information about students’ impulsivity facets to address their binge drinking and alcohol-related consequences.     

On the decomposition of life expectancy and limits to life

Life expectancy is a measure of how long people are expected to live and is widely used as a measure of human development. Variations in the measure reflect not only the process of ageing but also the impacts of such events as epidemics, wars, and economic recessions. Since 1950, the influence of these events in the most developed countries has waned and life expectancy continues to lengthen unabated. As a result, it has become more difficult to forecast long-run trends accurately, or identify possible upper limits. We present new methods for comparing past improvements in life expectancy and also future prospects, using data from five developed, low-mortality countries. We consider life expectancy in 10-year age intervals rather than over the remaining lifetime, and show how natural limits to life expectancy can be used to extrapolate trends. We discuss the implications and compare our approach with other commonly used methods.

Marxism and capitalist possession

This paper evaluates marxist attempts to identify a ‘class of possessors’ under capitalism. It suggests that such attempts are unsuccessful for three reasons. Firstly, marxism wrongly equates the agent of possession with the human individual. Secondly, its conception of the capitalist economy rests upon teleological assumptions. Thirdly, it wrongly asserts the priority of capitalist relations of production over and above their legal conditions of existence, causing it to misrecognise corporate forms of possession. After considering marxist attempts to theorise possession through the analysis of management and monopoly we consider a more fundamental question: whether it is possible to analyse possession/separation in conventional marxist class terms at all.     

Population policy and models of human nature

Conclusion Models of human nature are seldom clearly expressed by individuals; nevertheless, they are rooted deeply and may be crucial in the formulation and success of population policies. It appears that, for purposes of population policy, a few deep-rooted models can be distinguished and that these models are closely related to the developmental status of countries. Questions of political feasibility and program effectiveness could be analyzed within this framework and the classification proposed here could contribute to this goal.Revised version of a paper presented at the annual meetings of the Population Association of America, St. Louis, Missouri, April 21–23, 1977.

“Her Anger Frightens Me!” Using Group-Work Practice Principles and Feature Films in Teaching Clinical Practice in Mental Health

ABSTRACT

Combining group-work practice principles and the arts (feature films) can contribute to more effective teaching and enhance student clinical practice competency. By treating teaching as a form of group work and introducing a feature film into the classroom group, an instructor can reduce student-learning anxieties, teach core clinical concepts and skills, and enhance the classroom’s socioemotional climate. Vignettes demonstrate how this approach to teaching enriched students’ learning in an introductory clinical social work class on adult mental health.     

A Mixture Model for Longitudinal Partially Ranked Data

This article discusses the use of mixture models in the analysis of longitudinal partially ranked data, where respondents, for example, choose only the preferred and second preferred out of a set of items. To model such data we convert it to a set of paired comparisons. Covariates can be incorporated into the model. We use a nonparametric mixture to account for unmeasured variability in individuals over time. The resulting multi-valued mass points can be interpreted as latent classes of the items. The work is illustrated by two questions on (post)materialism in three sweeps of the British Household Panel Survey.     

The Future of Serials Cataloging,CONSER and the ISSN: Conversations from the Field

What does the future hold for the shape of serials to come and for cataloging these and other continuing resources? How should cataloging change to cope with still-unknown types of continuing resources? Will there still be a need for cataloging? For CONSER? For ISSN? How can libraries position themselves to partner with nonlibrary metadata creators in a future linked data environment? Four serials experts discuss these and other questions in a free-ranging conversation about the future of serials cataloging.
