Principles that underpin effective school-based drug education

This study identifies the conceptual underpinnings of effective school-based drug education practice in light of contemporary research evidence and the practical experience of a broad range of drug education stakeholders. The research involved a review of the literature, a national survey of 210 Australian teachers and others involved in drug education, and structured interviews with 22 key Australian drug education policy stakeholders. The findings from this research have been distilled and presented as a list of 16 principles that underpin effective drug education. In broad terms, drug education should be evidence-based, developmentally appropriate, sequential, and contextual. Programs should be initiated before drug use commences. Strategies should be linked to goals and should incorporate harm minimization. Teaching should be interactive and use peer leaders. The role of the classroom teacher is central. Certain program content is important, as is social and resistance skills training. Community values, the social context of use, and the nature of drug harm have to be addressed. Coverage needs to be adequate and supported by follow-up. It is envisaged that these principles will provide all those involved in the drug education field with a set of up-to-date, research-based guidelines against which to reference decisions on program design, selection, implementation, and evaluation.     

The Community Readiness Survey. Development and initial validation

This article reports on the development and evaluation of a mail survey measuring population attitudes toward substance use of potential receptivity of communities to different prevention efforts. The Community Readiness Survey was designed through a series of prevention practitioner and consultant meetings and focus groups. Psychometric evaluation revealed five distinct domains: perception of alcohol, tobacco, or other drug problem; support for prevention; permissive attitudes toward teen substance use; perception of adolescent access; and perception of community commitment. Evidence of construct validity was demonstrated by the small but significant relationships between selected scale scores and community readiness as evaluated by prevention planners.     

Verflochtene Mobilitäten und ihr Management. Mobilitätspraktiken von Expatriate-Managern und ihren <Emphasis Type="Italic">‚trailing spouses‘</Emphasis> im Auslandseinsatz

This article analyzes forms and enabling practices of expatriate mobility, i. e. the mobility of managers and skilled professionals assigned to a foreign subsidiary of their company. We will show that (1) expatriate mobility has to be conceived of as complex entangled mobilities that add up to a hyper-mobility, and (2) that this hyper-mobility inevitably depends on the active mobility work of the expatriates’ ‘trailing spouses’. Thus, it becomes clear that the mobility management on which expatriate mobility depends is highly gendered. By focusing on the specifics of expatriate mobility, the article also opens up new theoretical perspectives for mobility research in general.     

Joint confidence regions in the multivariate calibration problem

Consider a vector valued response variable related to a vector valued explanatory variable through a normal multivariate linear model. The multivariate calibration problem deals with statistical inference on unknown values of the explanatory variable. The problem addressed is the construction of joint confidence regions for several unknown values of the explanatory variable. The problem is investigated when the variance covariance matrix is a scalar multiple of the identity matrix and also when it is a completely unknown positive definite matrix. The problem is solved in only two cases: (i) the response and explanatory variables have the same dimensions, and (ii) the explanatory variable is a scalar. In the former case, exact joint confidence regions are derived based on a natural pivot statistic. In the latter case, the joint confidence regions are only conservative. Computational aspects and the practical implementation of the confidence regions are discussed and illustrated using an example.     

Competent and Warm but Unemotional: The Influence of Occupational Stereotypes on the Attribution of Emotions

The present research aims to assess how occupational stereotypes, and in particular, stereotypes about doctors, influence the observers’ perception of the emotions expressed by members of this group. For this, 60 men and women judged the emotions of women who expressed either happiness, anger, sadness, or a neutral expression and whose faces were either uncovered or covered with a surgical mask, a niqab, or a hat and scarf such that only an identical portion of the face around the eyes was visible. Congruent with the occupational stereotype, women dressed as doctors were perceived highest on competence and warmth, but also as emotionally restrained such that they were rated as experiencing lower levels of emotions relative to the same women wearing other face covers or with uncovered faces.     

A note On outlier sensitivity of Sliced Inverse Regression

Sliced Inverse Regression (SIR) is a promising technique for the purpose of dimension reduction. Several properties of this method have been examined already, but little attention has been paid to robustness aspects. In this article, we focus on the sensitivity of SIR to outliers and show in what sense and how severely SIR can be influenced by outliers in the data.     

“Crowding in” or “crowding out”? An examination of the impact of the welfare state on generalized social trust

Generalized social trust is correlated with increased levels of civic engagement, lower crime rates, and greater economic growth. Many scholars believe that equality provides the conditions in which social trust can flourish. Thus, welfare programs might be one way to generate social trust. However, the relationship between social spending and trust is contested: Some argue it is negative, while others argue it is positive. This study examined the effects of total social welfare expenditures on social trust in 18 OECD countries, holding constant individual characteristics, country characteristics, and country and year effects. Fixed effects analyses indicate that every additional percent of gross domestic product spent on social expenditures 5 years prior is associated with a 4.7 percent increased likelihood that respondents of that country will endorse trusting other people. Further testing for reverse causality found no significant association between trust and later social expenditures, supporting the claim that expenditures drive trust instead of the reverse.
