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.  相似文献

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.  相似文献

This paper provides new empirical evidence on primary pupils’ views on school attendance in Wales at Key Stage 2. The research was conducted as part of the specific evidence commissioned by the Welsh Assembly Government (WAG) for the National Behaviour and Attendance Review (NBAR) in Wales which was chaired by the lead author. The findings indicate that nearly every child and young person who participated in the specially convened focus groups, in practically every setting, had a good awareness of the benefits of attending school regularly. They were all acutely aware of the potential consequences of non‐attendance both within their current setting and as it could potentially affect their later chances in life. They also understood the law regarding school attendance. They were clear about the attendance regulations within their own school settings. They were however, particularly concerned about bullying in all its forms, the use of supply teachers and “boring” teaching styles. Rewards for good attendance were generally appreciated. The implications of the findings are considered. This paper is the first of its kind to be undertaken in Wales and in the field of school attendance and opens up considerable possibilities for further research.  相似文献

This rejoinder provides a reply to comments on a middle school college readiness index, which was devised to generate earlier and more nuanced readiness diagnoses to K‐12 students. Issues of reliability and validity (including construct underrepresentation and construct‐irrelevant variance) are discussed in detail. In addition, comments from Lazowski et al. and Mattern et al. provide a useful summary of areas where more college readiness research is needed. This rejoinder elaborates on those essential next steps, including deploying readiness indicators in school settings. Advances in the measurement of noncognitive skills will require more validity research using more contemporary data from authentic school settings. Still, the middle school college readiness index is a promising proof of concept, demonstrating the utility of diverse, early measures to support targeted, timely interventions.  相似文献

This study examines the communication skill similarity between fathers and daughters. Participants were 186 daughters who identified perceptions of both their own communication competence and their father's communication competence. Results indicated that perceived similarity was related to relational satisfaction and quantity of communication. Using the Family Communication Pattern (FCP) model, father-daughter relationship satisfaction and communication skill similarity varied depending on the family type (i.e., consensual, pluralistic, protective, laissez-faire).  相似文献

Childhood adversity is associated with altered reward processing, but little is known about whether this varies across distinct types of adversity. In a sample of 94 children (6–19 years), we investigated whether experiences of material deprivation, emotional deprivation, and trauma have differential associations with reward-related behavior and white matter microstructure in tracts involved in reward processing. Material deprivation (food insecurity), but not emotional deprivation or trauma, was associated with poor reward performance. Adversity-related influences on the integrity of white matter microstructure in frontostriatal tracts varied across childhood adversity types, and reductions in frontostriatal white matter integrity mediated the association of food insecurity with depressive symptoms. These findings document distinct behavioral and neurodevelopmental consequences of specific forms of adversity that have implications for psychopathology risk.  相似文献

The study investigated the relationships between student perceptions of instructor power and classroom justice. Partial correlations controlling for student grade expectations indicated that student perceptions of their instructors’ use of coercive, legitimate, referent, and expert power were related to perceptions of fairness in the classroom. Student perceptions of instructor use of reward power were not related to perceptions of any type of classroom justice.  相似文献

Elite tennis is characterised by repeated bouts of up to 5-set match play, yet little is known about the technical requirements of shots played. This study therefore investigated technical performance changes over consecutive days of prolonged, simulated tennis match play. A total of 7 well-trained men tennis players performed 4 consecutive days of competitive 4-h match play. Matches were notated to determine between-day changes in groundstroke and serve performance, as well as point and match durations. Changes ≥75% likely to exceed the smallest important effect size (0.2) were considered meaningful and represented as effect size ± 90% confidence interval. Effective playing time reduced on days 3 and 4, alongside likely increases in “stretch” groundstrokes over the 4 days (mean effect size ± 90% confidence interval; 0.57 ± 0.38) and “stretch” backhand returns on days 2 and 3 (0.39 ± 0.54 and 0.67 ± 0.55). Relative unforced errors increased on day 4 (vs. day 2; 0.36 ± 0.22) and second-serve winning percentage reduced after day 1 (?0.47 ± 0.50). Further, a likely increase in emotional outbursts characterised day 3 (vs. day 2; 0.73 ± 0.57). Consecutive-day match play impairs hitting accuracy, stroke positioning and emotional responses; an understanding of which prepares players for elite-standard tennis tournament play.  相似文献

The effects of pomegranate extract (PE) supplementation were evaluated on high-intensity exercise performance, blood flow, vessel diameter, oxygen saturation (SPO2), heart rate (HR), and blood pressure (BP). In a randomized, crossover design, nineteen recreationally resistance-trained participants were randomly assigned to PE (1000?mg) or placebo (PL), which were consumed 30?min prior to a repeated sprint ability (RSA) test and repetitions to fatigue (RTF) on bench and leg press. The RSA consisted of ten six-second sprints on a friction-loaded cycle ergometer with 30?s recovery. Brachial artery blood flow and vessel diameter were assessed by ultrasound. Blood flow, vessel diameter, SPO2, HR, and BP were assessed at baseline, 30?min post ingestion, immediately post exercise (IPost), and 30?min post exercise (30minPost). With PE, blood flow significantly increased IPost RSA (mean difference?=?18.49?mL?min?1; P?<?.05), and IPost and 30minPost RTF (P?<?.05) according to confidence intervals (CI). Vessel diameter increased significantly 30minPost RSA according to CI and resulted in a significant interaction IPost and 30minPost RTF (P?<?.05). With PE, according to CI, average and peak power output increased significantly in sprint 5 of the RSA (P?<?.05). There was no significant difference between PE and PL for bench (P?=?.25) or leg press (P?=?.15) repetitions. Acute PE supplementation enhanced vessel diameter and blood flow, suggesting possible exercise performance enhancement from increased delivery of substrates and oxygen. The acute timing and capsule form of PE may be advantageous to athletic populations due to ergogenic effects, taste, and convenience.  相似文献
