In a recent meta-analysis evaluating the relationship between chorioamnionitis and cerebral palsy, we found that chorioamnionitis is a risk factor for both cerebral palsy and cystic periventricular leukomalacia (cPVL). The current paper extends the meta-analysis by including studies published in the year 2000, and by further evaluating the causes of heterogeneity among individual study results. Using a random effects model, clinical chorioamnionitis was significantly associated with both cerebral palsy (RR 1.9, 95% CI 1.5-2.5) and cPVL (RR 2.6, 95% CI 1.7-3.9). Sources of heterogeneity included widely varying practices in the diagnosis of clinical chorioamnionitis, different gestational age characteristics, and varying study year. We conclude that based on the available literature, chorioamnionitis is a risk factor for both cerebral palsy and cPVL.  相似文献

This study examined the school experiences and academic achievement of 46 adolescents in families who experienced homelessness and 87 permanently housed adolescents whose families received public assistance. Measures taken after the homeless students were rehoused showed that both groups valued school highly and were similar in cognitive abilities assessed with the similarities subtest of the Wechsler Intelligence Scale for Children—Revised (WISC-R). Formerly homeless students had more school mobility, more grade retention, and worse school experiences by mother report and lower plans for post-secondary education by self-report. Both groups scored poorly on standardized tests of academic achievement. Homelessness was associated with further declines in achievement during the period of maximal residential disruption, but did not have effects 5 years later.  相似文献

Contextual variations in mother-child and father-child verbal communication were examined among 80 U.S. families from Kansas who were predominately Caucasian (85%) and middle-class. There were 41 girls and 39 boys between 15- and 18-months-old observed with their mothers and fathers in separate play and caregiving laboratory situations. Parent and child behaviors were coded for verbal initiation and response strategies. MANOVA’s revealed more differences between mother’s and father’s verbal communication strategies in the play context than the caregiving context. Boy’s and girl’s verbal communication was relatively similar across contexts. The interactions between gender and context are discussed in relation to gender role development in the family.  相似文献

African American women (n = 42) and European American women (n = 46) were queried regarding their comfort level discussing various sexual health topics with hypothetical counselors who were varied by race (African American vs. European American) or counseling value (culturally sensitive vs. knowledgeable). Contrary to hypotheses, European American participants were more comfortable with the knowledgeable African American counselor and the culturally sensitive European American counselor, while African American women showed no preference. Implications are discussed for improving sexual health counseling services for African American and European American women with consideration of client sexual attitude and race of counselor in order to reduce disparities in sexual health.  相似文献

This study examines the role that context plays in links between relative balance, or mutuality in parent–child interaction and children's social competence. Sixty‐three toddlers and their parents were observed in a laboratory play session and caregiving activity (i.e. eating snack). Mutuality was operationalised as the relative balance in (a) partners' compliance to initiations, and (b) partners' expression of positive emotion. Caregivers rated children's social competence with peers, and children's prosocial and aggressive behaviour with peers was observed in their childcare arrangement. Contextual differences were observed in the manifestation of parent–child mutuality, with both mother–child and father–child dyads displaying higher mutual compliance scores in the play context than in the caregiving context. Father–child dyads also displayed higher levels of shared positive emotion during play than during the caregiving context. There were no differences in a way that parent–child mutuality during play and caregiving was associated with children's social competence with peers. Overall, the results suggest that parent–child mutuality is a quality of parent–child interaction that has consistent links to children's peer competence regardless of the context in which it occurs.

The present study addressed whether security of attachment is differentiated by quality of parenting and quantity of exposure to child care. Sixty mothers participated with their 14‐month‐old infants, who by the age of 12‐months had received either exclusive maternal care, or varying degrees of exposure to child care. Levels of attachment security were assessed through maternal completion of the Attachment Q‐Set(AQS); parenting quality was assessed through observations of mother–infant interactions during structured tasks. The scores that less sensitive mothers assign their toddlers is higher when their children are in child care for more hours per week; whereas the scores that more sensitive mothers assign their toddlers is lower when their children are in child care for more hours per week. These contrasting patterns suggest that the effects of parenting style on attachment security are moderated by quantity of exposure to child care. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

The effectiveness of decision-making teams depends largely on the quality of information processing. Prior research has shown that guided team reflexivity and team feedback are important means of advancing team information processing and outcomes. However, the nature of the relationships, and how these relate to team regulatory processes, cognitive emergent states, and ultimately team performance, is currently poorly understood. Drawing on reflexivity and team information-processing theory, we proposed and found that teams that received guided team reflexivity or a combination of both guided reflexivity and feedback showed higher levels of actual reflection than teams that received neither a reflexivity intervention nor feedback. Conditional process analysis showed that the effects of team reflection on team performance improvement were mediated by a path from shared team mental models to shared task mental models and to adaptation. Finally, we also expected that team reflection would be lower in virtual teams than in face-to-face teams. These hypotheses were tested experimentally among 98 student teams that communicated either face-to-face or virtual (via chat) while completing a collective decision-making task. The information distribution among team members constituted a hidden profile. The results supported all our hypotheses, except for the one relating to virtuality.  相似文献

As a part of classroom management, teachers face the question of how and where to seat their students. However, it is far from clear what considerations teachers have when making seating arrangements. Therefore, in this study seating arrangement considerations from 50 teachers in grades 4–6 of elementary school were assessed. In Phase 1, teachers were interviewed about their goals and considerations for classroom seating arrangements. Teachers mentioned between 2 and 19 reasons for placing students at specific places in the classroom, with mostly academic considerations. They mainly preferred arrangements in small groups to promote student cooperation. In Phase 2, teachers completed a questionnaire about seating arrangements. This allowed us to examine individual differences between teachers related to gender, years of experience, and beliefs, and the concurrence between the interview and questionnaire data. Teachers reported multiple and various considerations for seating arrangements. Correlations with their general student-oriented or subject-oriented beliefs and personal characteristics were low. The concurrence between measurement methods also was low. The discussion focused on teacher awareness of classroom seating arrangements as an important part of classroom management and a tool for prevention and intervention.  相似文献
