Is academic tracking related to gains in learning competence? Using propensity score matching and differential item change functioning analysis for better understanding of tracking implications

This study analyzes gains in cognitive components of learning competence with respect to cohorts based on ability tracking in a Czech longitudinal study. Propensity score matching is used to form parallelized samples of academic and non-academic track students and to eliminate the effect of selective school intake. We applied regression models on the total scores to test for the overall track effect. Furthermore, we analyze scores and gains on the subscores and check for differential item functioning in Grade 6 and in change to Grade 9. While after 3 years, no significant difference between the two tracks was apparent in the total learning competence score, we did, however, find significant differences in some subscores and in the functioning of some items. We argue that item-level analysis is important for deeper understanding of the tracking implications and may provide the basis for more precise evidence-based decisions regarding the tracking policy.     

Healing after traumatic events: Aligning interventions with cultural background and religious and spiritual beliefs

Historically, disaster response efforts have focused primarily on basic physical survival and safety—addressing medical emergencies and ensuring adequate shelter and supplies of food and water. However, in addition to physical survival, relief efforts must also consider strategies to promote emotional healing and psychological well-being. In particular, those who intervene must consider the acceptability of intervention strategies, taking into account survivors' cultural background, religious customs, and spiritual beliefs. This article offers recommendations to better align school-based therapeutic interventions with children's religious and spiritual beliefs.

The relations among child negative interactive behavior,child temperament,and maternal behavior

Negative behavior toward the mother during toddlerhood might be a marker of increased risk for maladjustment. The aim of the present study was to examine the possible antecedents of toddler boys’ negative behavior observed in interaction with the mother: child temperament, and maternal behavior toward the child. We studied the moderating and mediating role of two dimensions of maternal behavior, sensitivity and intrusiveness, in the relationship between children's temperamental traits (frustration, soothability and activity level), on the one hand, and child negative behavior, on the other hand. The sample consisted of 112 mother–son dyads observed when the child was 17 months old. A temperament questionnaire was completed by the mothers. Child negative interactive behavior, maternal sensitivity and intrusiveness were observed at home during a 13-min play session. Maternal sensitivity was negatively related to child negative interactive behavior regardless of child temperament. Maternal intrusiveness, however, moderated the relation between activity level and negative behavior, i.e., children with high activity level showed higher levels of negative behavior especially when the mother was highly intrusive. Furthermore, maternal intrusiveness acted as a mediator in the relation between soothability and negative behavior, i.e., low soothability was linked to higher maternal intrusiveness, which in turn was associated with higher negative behavior.     

Neck-controlled sensitivity study on nano-grain SnO_2 gas sensors

1. Introduction SnO2 is an n-type semiconductor with rutile crystal structure and with a wide band gap of about 3.6 eV. SnO2 has a wide range of applications as photo-detectors, heat mirrors, transparent electrodes for solar cells, conductive filler, thick resistors, catalysts and gas sensors. One of the most important applications of SnO2 lies in gas sensors [1]. SnO2 gas sensors have been attracting much attention [2-5] because of their many advantages over current technologies for detect…

浅论杜牧对词体的影响

晚唐诗歌对词体的定型产生了深刻的影响。其中杜牧的诗歌尤其是七言绝句．从以下三个方面对词体发生着影响：杜牧诗歌的隐约深细为词体主流意境的形成导夫先路；杜牧诗歌将伤眷伤别的题材演绎得细腻多情，朦胧要缈，为词体所继承；杜牧诗酒风流的生活为后世词人提供了写作素材和写作的心境。前两个方面又都和晚唐文人与两宋文人更偏重隐约精微的审美心态有关。
