Enhancing Peer Interaction in Early Childhood Special Education: Chains of Children’s Initiatives, Adults’ Responses and Their Consequences in Play

This article focuses on the initiatives taken by children and the responses given by professional adults with regard to the pedagogy of enhancing peer interaction among diverse learners. The study took place in four integrated special groups of public early childhood education. In groups of this kind, typically developing children and those with special educational needs (SEN) spent time together on a daily basis. We analysed 12 videotaped play sessions with 33 (3- to 6-year-old) children and 10 adults to examine the children’s initiatives, the adults’ responses, and the consequences that ensued. The study revealed verbal and nonverbal initiatives followed by a variety of responses scaffolding the children’s interaction and participation. However, the nonverbal or faint initiatives, especially those taken by the children with SEN, were at risk of being unnoticed or ignored. These findings call for professional reflection on pedagogical sensitivity in recognizing and responding to the initiatives of children.</p

Association of screen time with long-term stress and temperament in preschoolers: results from the DAGIS study

Screen time is increasing rapidly in young children. The aim of this study was to examine associations of long-term stress and temperament with screen time in Finnish preschool children and the moderating role of socioeconomic status. Cross-sectional DAGIS data were utilized. Long-term stress was assessed using hair cortisol concentration, indicating values of the past 2 months. Temperament was reported by the parents using the Children’s Behavior Questionnaire (the Very Short Form), and three broad temperament dimensions were constructed: surgency, negative affectivity, and effortful control. Screen time was reported by the parents over 7 days. The highest education level in the household was used as an indicator of socioeconomic status. In total, 779 children (mean age, 4.7 ± 0.9 years, 52% boys) were included in the study. Of the temperament dimensions, a higher effortful control was associated with less screen time (B = − 6.70, p = 0.002). There was no evidence for an association between hair cortisol concentration and screen time nor a moderating role of socioeconomic status in the associations (p > 0.05).Conclusion: Our findings indicate that preschool children with a higher score in effortful control had less screen time. Because effortful control reflects general self-regulatory abilities, promoting these skills may be effective in reducing screen time in young children.</p

Microbial Ligand Costimulation Drives Neutrophilic Steroid-Refractory Asthma

Asthma is a heterogeneous disease whose etiology is poorly understood but is likely to involve innate responses to inhaled microbial components that are found in allergens. The influence of these components on pulmonary inflammation has been largely studied in the context of individual agonists, despite knowledge that they can have synergistic effects when used in combination. Here we have explored the effects of LPS and β-glucan, two commonly-encountered microbial agonists, on the pathogenesis of allergic and non-allergic respiratory responses to house dust mite allergen. Notably, sensitization with these micro-bial components in combination acted synergistically to promote robust neutrophilic inflammation, which involved both Dectin-1 and TLR-4. This pulmonary neutrophilic inflammation was corticosteroid-refractory, resembling that found in patients with severe asthma. Thus our results provide key new insights into how microbial components influence the development of respiratory pathology
