Development of a Questionnaire to Assess University Students’ Intentions to Use Behavioral Alcohol-Reduction Strategies

Abstract

Objective: To evaluate the psychometric properties of a new self-report questionnaire designed to assess college students’ intentions to employ 31 specific alcohol-reduction strategies. Method: Students attending a large public university were recruited to complete alcohol-reduction, drinking history, and personality questionnaires online. Results: Based on item–total correlations and principal components analysis, the authors eliminated 3 items and calculated average intention ratings across the remaining 28 items. The resulting scale had appropriate unidimensionality and excellent internal consistency. Correlations of intention questionnaire scores with measures of drinking history, alcohol outcome expectancies, sensation seeking, and impression management provided some support for criterion and discriminant validity of the questionnaire. Conclusion: This questionnaire could be employed as an outcome measure to evaluate prevention programs and as a clinical tool to identify clients who have little intention to employ drinking reduction strategies in heavy drinking situations.

On Optimal Point and Block Prediction in Log-Gaussian Random Fields

Abstract.  This work discusses the problems of point and block prediction in log-Gaussian random fields with unknown mean. New point and block predictors are derived that are optimal in mean squared error sense within certain families of predictors that contain the corresponding lognormal kriging point and block predictors, as well as a block predictor originally motivated under the assumption of 'preservation of lognormality', and hence improve upon them. A comparison between the optimal, lognormal kriging and best linear unbiased predictors is provided, as well as between the two new block predictors. Somewhat surprisingly, it is shown that the corresponding optimal and lognormal kriging predictors are almost identical under most scenarios. It is also shown that one of the new block predictors is uniformly better than the other.     

A global energy network? The expansion and integration of non‐triad national oil companies

It is widely perceived that the rising influence of state‐owned energy companies from outside the traditional triad (USA, EU, Japan) is transforming the structure of the global energy market and generating a new wave of resource‐nationalism. There is, however, little empirical analysis of how this process has unfolded. Addressing this empirical gap, in this article I employ a longitudinal social network analysis of the changing corporate relations of five major non‐triad state‐owned energy companies in the period 1997–2007. The findings indicate that, in terms of corporate relations, alongside the global expansion of the non‐triad state‐owned energy companies, there was also an increased integration between them and the private energy companies during this decade. This implies that apart from the resurgence of resource‐nationalism – frequently highlighted in academia and politics – this period also witnessed an increasing transnationalization of the global energy market.
