Helsen, Gilis and Weston (2006) err in testing the optical error hypothesis

In this commentary, we react to the recent study by Helsen, Gilis and Weston (2006) on judging offside in football. Helsen et al. claim that their data falsify the optical error hypothesis presented by Oudejans et al. (2000). However, as we will elucidate here, they misinterpret this hypothesis and present a data set that is seriously flawed, and hence not suited to test it. Therefore, their conclusions regarding the optical error hypothesis are in error.

Computer support in a rural setting: A comparison of computer-assisted and handwritten evaluation reports

The present blind study compared the quality of psychoeducational reports generated under two conditions. On the average, reports written with computer assistance were rated to be of higher quality than those prepared by hand. Also presented are data validating the large expenditure of staff time on report preparation, along with estimates of the time saving that may be realized with computer assistance. The relevance of computer support to relatively isolated, rural-based clinical staff is discussed.     

对佛教体验的再思考:皈依与神迹--佛教体验的"家族相似性"特征

佛教中的体验与“家庭相似性”关联何在,为之辩护的论题包括两部分：（1）与其他方式相比,把皈依概念和神迹概念纳入体验概念可以使我们对佛教体验形成一种更为恰当的观点,而这一观点能够表明佛教的宣称与科学的经验主义的宣称之间的区别（前提1-10）;（2）关于界定体验之所是的“家族相似性”理念,本文结论是,皈依与神迹是对佛教中的体验所作出的非实在论的“家族相似性”定义中的两个要素（前提11-13）.     

Roadkill on the electronic highway? The threat to the mathematical literature

This article begins with an analysis of reliability and usability in the mathematical literature. Mathematical practice is seen to be adapted to very high standards in these respects, and quite sensitive to even modest declines in quality. Unfortunately most scenarios for the transition to electronic publication suggest serious loss of quality. This is a problem special to mathematics: other sciences are adapted to lower standards, and should be much less sensitive to changes. Some ways to prevent this decline are suggested.

Assessing Marital Conflict from the Child''s Perspective: The Children''s Perception of Interparental Conflict Scale

Guided by Grych and Fincham's theoretical framework for investigating the relation between interparental conflict and child adjustment, a questionnaire was developed to assess children's views of several aspects of marital conflict. The Children's Perception of Interparental Conflict Scale (CPIC) was initially examined in a sample of 222 9-12-year-old children, and results were cross-validated in a second sample of 144 similarly aged children. 3 factor analytically derived subscales (Conflict Properties, Threat, Self-Blame) demonstrated acceptable levels of internal consistency and test-retest reliability. The validity of the Conflict Properties scale was supported by significant relations with parent reports of conflict and indices of child adjustment; the Threat and Self-Blame scales correlated with children's responses to specific conflict vignettes. The CPIC thus appears to be a promising instrument for assessing perceived marital conflict, and several issues regarding its interpretation are discussed.
