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.

A Parsons Tale: Tractarian Reflections on a Semantical Paradox

According to Charles Parsons, a liar sentence does not express a proposition at the level of its primary use but does at the level where it is subjected to semantic interpretation. Thus, richer ontological resources unavailable at the level of primary use are available at the level of interpretation. In response to the objection that the correct semantic interpretation of a liar sentence is thereby distorted, I explain how Wittgenstein’s repudiation of “logical objects” and the Tractarian notion of an intrinsically iterative operation show that the liar sentence’s primary use anticipates but does not presuppose the richer interpretive ontology.     

Real-world implications of high-performance competencies and strategic management simulation technology

The construct and criterion-related validity of 11 High-Performance Competencies (H-PC) are explored through data collected by three highly reliable methods: work shadowing, assessment centres, and Strategic Management Simulation Technology. A large international managerial sample indicates that some H-PC are more highly developed than others. This suggests that managers may have a restricted capacity to co-operatively address the multidimensional issues that loom large today. Strategic Management Simulation Technology is discussed as a way of developing a more balanced leadership capability profile and enhancing desirable real-world outcomes.
