Social-emotional effects of early childhood education programs in Tulsa

This article assesses the effects of Tulsa, Oklahoma's early childhood education programs on social-emotional outcomes, examining teacher ratings of children's behavior from the Adjustment Scales for Preschool Intervention and a measure of attentiveness using fixed effects regressions with propensity score matching. The sample includes 2,832 kindergarten students in 2006, of whom 1,318 participated in the Tulsa Public Schools (TPS) pre-K program and 363 participated in the CAP of Tulsa County Head Start program the previous year. Program participation was associated with lower timidity and higher attentiveness for TPS pre-K alumni and a marginally significant reduction in timidity for Head Start alumni. Results were similar for the free lunch-eligible subsample. We conclude that high-quality, school-based preschool programs can enhance social-emotional development.     

Collaboration of Teacher Education and Child Disability Health Care: Transdisciplinary Approach to Inclusive Practice for Early Childhood Pre-Service Teachers

The purpose of this paper is to describe the collaborative efforts between an Early Childhood Teacher Education Program and a Child Disability Health Care Program to incorporate a transdisciplinary model in the preparation of early childhood teachers in inclusive practice. Recent studies suggest essential components of teacher preparation in early childhood inclusion include: helping students construct a positive image of inclusive practice, incorporating a family-centered approach, and collaborating and relationship building across disciplines (Campbell et al. 2003; Pretti-Frontczak et al. 2002 and Able-Boone et al. 2002). In this paper, we describe the collaboration between the University of Michigan-Dearborn Early Childhood Teacher Education Program and Oakwood Health Care Center for Exceptional Families to co-teach and mentor early childhood pre-service teachers as they create a family-centered event for children with disabilities and their typically developing peers in a natural environment. Researchers analyze student reflection papers about the family-centered event for evidence of new learning about child disability and inclusive practice. The reflections demonstrate the power of the students’ active role in creating and implementing family-centered activities in a collaborative context. Other key reflective components include rewards and challenges in creating inclusive contexts, integral role of families in supporting child relationships in natural settings, and collaboration and teaming.     

Socialization of coping with community violence: influences of caregiver coaching, modeling, and family context

A socialization model of coping with community violence was tested in 101 African American adolescents (55% male, ages 9-13) and their maternal caregivers living in high-violence areas of a mid-sized, southeastern city. Participants completed interviews assessing caregiver coping, family context, and child adjustment. Caregiver-child dyads also discussed a film clip depicting community violence. Parental coaching (caregivers' strategies suggesting how to cope) and child-reported coping were coded from the discussion. Coaching, modeling (caregivers' own coping), and family context each contributed to children's coping with violence. Children's problem-focused coping in response to violence had the strongest associations with changes in their adjustment 6 months later. Implications for interventions with youth and families are discussed.     

How doctors search: A study of query behaviour and the impact on search results

Professional, workplace searching is different from general searching, because it is typically limited to specific facets and targeted to a single answer. We have developed the semantic component (SC) model, which is a search feature that allows searchers to structure and specify the search to context-specific aspects of the main topic of the documents. We have tested the model in an interactive searching study with family doctors with the purpose to explore doctors’ querying behaviour, how they applied the means for specifying a search, and how these features contributed to the search outcome. In general, the doctors were capable of exploiting system features and search tactics during the searching. Most searchers produced well-structured queries that contained appropriate search facets. When searches failed it was not due to query structure or query length. Failures were mostly caused by the well-known vocabulary problem. The problem was exacerbated by using certain filters as Boolean filters. The best working queries were structured into 2–3 main facets out of 3–5 possible search facets, and expressed with terms reflecting the focal view of the search task. The findings at the same time support and extend previous results about query structure and exhaustivity showing the importance of selecting central search facets and express them from the perspective of search task. The SC model was applied in the highest performing queries except one. The findings suggest that the model might be a helpful feature to structure queries into central, appropriate facets, and in returning highly relevant documents.     

Fetal Genotype for the Xenobiotic Metabolizing Enzyme NQO1 Influences Intrauterine Growth Among Infants Whose Mothers Smoked During Pregnancy

Maternal smoking during pregnancy retards fetal growth and depresses infant birth weight. The magnitude of these effects may be moderated by fetal genotype. The current study investigated maternal smoking, fetal genotype, and fetal growth in a large population sample of dizygotic twins. Maternal smoking retarded fetal growth in a dose-dependent fashion. In a subsample of 497 twin pairs whose mothers smoked during pregnancy, a functional polymorphism in the NAD(P)H:quinone oxidoreductase gene ( NQO1 Pro187Ser; rs1800566) was significantly associated with fetal growth within families. The effect was strongest among moderate smokers. This is the first demonstration that fetal genotype for an enzyme involved in tobacco smoke metabolism influences intrauterine growth independent of maternal genotype. Future studies should conduct formal tests of Fetal Genotype × Maternal Smoking interactions.     

Prenatal Antecedents of Newborn Neurological Maturation

Fetal neurobehavioral development was modeled longitudinally using data collected at weekly intervals from 24 to 38 weeks gestation in a sample of 112 healthy pregnancies. Predictive associations between 3 measures of fetal neurobehavioral functioning and their developmental trajectories to neurological maturation in the first weeks after birth were examined. Prenatal measures included fetal heart rate (FHR) variability, fetal movement, and coupling between fetal motor activity and heart rate patterning; neonatal outcomes include a standard neurologic examination ( n  =   97) and brainstem auditory evoked potential (BAEP; n  =   47). Optimality in newborn motor activity and reflexes was predicted by fetal motor activity, FHR variability, and somatic–cardiac coupling predicted BAEP parameters. Maternal pregnancy-specific psychological stress was associated with accelerated neurologic maturation.     

Construct validation of physical activity surveys in culturally diverse older adults: a comparison of four commonly used questionnaires

The purpose of this study was to establish validity evidence of four physical activity (PA) questionnaires in culturally diverse older adults by comparing self-report PA with performance-based physical function. Participants were 54 older adults who completed the Continuous Scale Physical Functional Performance 10-item Test (CS-PFP10), Physical Activity Scale for the Elderly (PASE), HAMPS Physical Activity Questionnaire for Older Adults, Yale Physical Activity Survey (YPAS), and modified Baecke questionnaire. The total PASE score, three outcome scores for the CHAMPS, and three summary indices for the YPAS were significantly correlated with total CS-PFP10 score. The modified Baecke exhibited no correlations with CS-PFP10 scores. The PASE, CHAMPS, and YPAS appear to be the most valid PA self-report questionnaires for culturally diverse older adults.
