Concurrent and longitudinal associations of peers' acceptance with emotion and effortful control in kindergarten.

The purpose of the study was to evaluate bidirectional associations between peer acceptance and both emotion and effortful control during kindergarten ( = 301). In both the fall and spring semesters, we obtained peer nominations of acceptance, measures of positive and negative emotion based on naturalistic observations in school (i.e.

Impact of High-Flow Nasal Cannula Use on Neonatal Respiratory Support Patterns and Length of Stay.

Background: Heated humidified high-flow nasal cannula (HFNC) is thought to be comparable with nasal CPAP. The effect of multimodality mid-level respiratory support use in the neonatal ICU is unknown. The objective of this work was to evaluate the effect of introducing HFNC on length of respiratory support and stay.

Bullying Perpetration and Victimization as Externalizing and Internalizing Pathways: A Retrospective Study Linking Parenting Styles and Self-Esteem to Depression, Alcohol Use, and Alcohol-Related Problems.

Background: Emerging research suggests significant positive associations between bullying and substance use behaviors. However, these studies typically focused either on the link between substance use and bullying perpetration or victimization, and few have conceptualized bullying perpetration and/or victimization as mediators.

Objective: In this study, we simultaneously tested past bullying perpetration and victimization as mediational pathways from retrospective report of parenting styles and global self-esteem to current depressive symptoms, alcohol use, and alcohol-related problems.

Emotional expression in school context, social relationships, and academic adjustment in kindergarten.

This study evaluated direct relations of both kindergarteners' (N = 301) naturalistically observed emotion in 2 different school contexts and early kindergarten verbal competence to academic adjustment (i.e., standardized measures of academic achievement, teacher-reported academic skills, teacher-reported and observed school engagement) and if these relations were mediated by teacher-reported conflict with students and by peer acceptance.

Requirement for peptide in alloreactive CD4+ T cell recognition of class II MHC molecules.

To examine the role of peptide in alloreactive class II MHC-restricted responses, we transfected I-A molecules into the Ag-processing defective mutant cell line, T2. Consistent with their defective Ag-processing phenotype, the T2 transfectants predominantly express SDS-unstable I-A molecules on their surface. These cells and phenotypically normal APCs were used to study primary and secondary alloreactive T cell responses in limiting dilution assays.
