[Cp(*)RhCl(PTA)(2)]X (PTA = 7-phospha-1,3,5-triazaadamantane) undergoes an H/D exchange process between the methyl groups of Cp(*) and D(2)O whose rate depends on the coordinating ability of the counterion X(-). Kinetic studies and DFT calculations indicate that deuteration involves the abstraction of a Me-Cp(*) proton by a coordinated OH(-); the formation of the latter seems to be facilitated ...

The objective of this study was to examine rates of depression among migrant children (MC) and left-behind children (LBC) as compared to non-left-behind children (NLBC) and also to examine the relationship between depression among these children and the quality of their parent-child and teacher-child relationships. This study collected data from a large sample of 3,759 children aged from 8 to 1...

The present study investigated specific teacher factors that potentially influence teacher–child relationships with preschool-age children. One demographic questionnaire and three rating scales were used to survey 152 head teachers of 3–6-year-old children in community-based childcare and preschool centers in one midwestern state. There were 46 teachers who reported on their relationship with a...

Working memory, used to temporarily store and mentally manipulate information, is important for children's learning. It is therefore valuable to understand which (contextual) factors promote or hinder working memory performance. Recent research shows positive associations between positive parent-child and teacher-student interactions and working memory performance and development. However, no s...

This study examines factors related to three dimensions of parent involvement in preschool: school-based involvement, home-based involvement, and the parent–teacher relationship. Participants were 154 predominantly African American parents recruited from two Head Start programs. Results of bivariate and canonical correlation analyses support the validity of a multidimensional, ecological concep...

Parent involvement in a child's education is consistently found to be positively associated with a child's academic performance. However, there has been little investigation of the mechanisms that explain this association. The present study examines two potential mechanisms of this association: the child's perception of cognitive competence and the quality of the student-teacher relationship. T...

OBJECTIVE To describe the relationship between ADHD symptom severity and quality of life (QoL) across three time points over a 12-month period and investigate whether sleep modifies this relationship. METHOD Children aged 5 to 13 years with ADHD were recruited from 21 pediatric practices across Victoria, Australia ( N = 392). Child QoL (parent-report) and ADHD symptoms (both parent- and teach...

This research investigated whether parent-teacher relationship quality mediated the relation between parents' motivational beliefs and children's adaptive functioning and externalizing behaviors. The sample consisted of kindergarten through third-grade children with behavioral concerns (N=206). Parents reported on their motivational beliefs (i.e., role construction and efficacy), and teachers r...

BACKGROUND This longitudinal study classified groups of children experiencing different trajectories of student-teacher relationship quality over the transition from preschool into school, and determined the strength of the association between different student-teacher relationship trajectories and childhood mental health problems in the second year of primary school. METHODS A community samp...

In this study, we explored informant characteristics as determinants of parent-teacher disagreement on preschoolers' psychosocial problems. Teacher characteristics were included in the analyses, in addition to child and parent factors. Psychosocial problems of 732 4-year olds from a Norwegian community sample were assessed by parents and teachers (CBCL-TRF). Furthermore, teachers reported on th...
