Primary School Correlates of Secondary School Achievement

This study is an investigation of the relationship between third grade final marks, achievement test scores, and subsequent achievement in elementary and secondary school. It was focused on the early identification of students for whom changes in the curriculum might be indicated.     

The Life Attitudes Schedule Short Form: An Abbreviated Measure of Life-Enhancing and Life-Threatening Behaviors in Adolescents

An abbreviated version of the Life Attitudes Schedule (LAS) was developed, consisting of 24 items, each representing one cell of the original LAS theoretical matrix (4 content categories × 2 behavior types × 2 valence). Items were retained on the basis of high correlations with LAS total score and low correlations with gender. Psychometric properties of the LAS Short Form were robust and the Short Form total score correlated .93 with the original LAS total score. As with the original LAS, boys reported more injury-related behaviors than girls. Future research and clinical directions are suggested.

Losing My Religion as a Natural Experiment: How State Pressure and Taxes Led to Church Disaffiliations between 1940 and 2010 in Germany

The sociological literature has produced a remarkably consistent picture of the quantitative patterns of religious disaffiliations in Western countries. This article argues, and demonstrates, that strong changes in a social context may lead individuals to disaffiliate rapidly, leading to very different aggregate effects from those in the “western model.” We use the unique situation of the separation of Germany from 1949 to 1989 and its subsequent reunification as a “natural experiment” to show just how much the relationships routinely found can be disrupted under changed conditions. The state socialist “treatment” affected religious disaffiliations in East Germany profoundly as it (a) made disaffiliations 10 times more probable in the East than in the West in the 1950s and 1960s, (b) shielded East German church members from factors that led to mass disaffiliations in the West in the late 1960s and early 1970s, (c) reversed the education‐disaffiliation link in the East, thus making disaffiliation more likely among the less educated, and (d) led to an especially strong increase in disaffiliations in the East right after the reunification
