Electronic games are popular and many children spend much time on this activity. Here we investigate whether the quantity of time children spend on gaming is related to their social development, making this the first study to examine this relationship in children. We examine prospective relations between time spent gaming and social competence in a community sample of Norwegian 6 year olds (n = 873) followed up at ages 8, 10, and 12, controlling for socioeconomic status, body mass index, and time spent gaming together with friends. Results revealed that greater social competence at both 8 and 10 years predicted less gaming 2 years later and that more age-10 gaming predicted less social competence at age 12 but only among girls. 相似文献

Students learning to read in more than one language are a growing population in schools. Early screening and identification of reading difficulties may lead to better outcomes for all students. Oral reading fluency (ORF) is one tool shown to be both a reliable measure of reading and an accurate method to identify students at risk for poor reading outcomes. This study synthesized available validity evidence for ORF with biliterates. All included studies (n = 31) were conducted with English language learners in grades K–8. Results suggested that although ORF is correlated with reading outcomes, the accuracy of ORF to identify English learners at risk of poor reading outcomes does not meet criteria. The strength of validity evidence differed by language proficiency of participants. Finally, the quality of the reviewed studies was low in critical areas. 相似文献

The generality of a multilevel factorial model of social competence (SC) for preschool children was tested in a 5‐group, multinational sample (N = 1,540) using confirmatory factor analysis. The model fits the observed data well, and tests constraining paths for measured variables to their respective first‐order factors across samples also fit well. Equivalence of measurement models was found at sample and sex within‐sample levels but not for age within sample. In 2 groups, teachers’ ratings were examined as correlates of SC indicators. Composites of SC indicators were significantly associated with both positive and negative child attributes from the teachers’ ratings. The findings contribute to understanding of both methodological and substantive issues concerning SC in young children. 相似文献

This article presents results from an innovative social work field education program, which prepares BSW and MSW students to work in interdisciplinary teams with congregational nurses as they serve persons age 55+ or older. The Congregational Social Work Education Initiative is a field education project based on an applied interdisciplinary model, whereby social work students at the graduate and undergraduate level partner with congregational nurses to serve at-risk members of congregations and religious affiliated organizations (RAOs). Students and nurses provide free health, mental health, and wellness services to address individual, family, group, and community health, mental health, and housing issues. Funded by community health foundations, it trains BSW and MSW students for professional practice in congregational and community religious affiliated settings through interdisciplinary and collaborative methods. Information on the development of the model and case illustrations are provided so other social work educational programs and congregational nurse programs might duplicate its success. 相似文献

Abstract Our purpose was to determine the aerobic capacities (VO2max) of a group of black female adolescents (age = 11.4 ? 15.8 years) randomly chosen from a single urban school. Of 91 girls selected, 64 performed an incremental treadmill running test to volitional exhaustion and achieved VO2max as determined from expired gas measures. Other measures included height (m), weight (kg), and calf and triceps skinfolds (for % fat estimates). Girls were also asked whether they had achieved menarche. VO2max averaged 37.3 ± 6.2 ml·kg?1 ·min?1 and was significantly correlated (r[62]) with height (?.32, p < .01), body mass index (?.63, p < .001), and % fat (?.65, p < .001) but not with age (?.16, p > .10). Postmenarchal girls were significantly taller and older than premenarchal girls. Contrary to previous studies, the girls' VO2max values were not related to biological age. Our subjects' aerobic capacity values averaged 14% less than those of nonblack U.S. female adolescents previously reported in the literature. This difference in VO2max was primarily a function of body weight. Study implications support the possibility that overweight in adult black women may originate prior to or during early adolescence. Future longitudinal studies should be designed to investigate the effects of aerobic fitness on cardiovascular risk factor reduction in black adolescent girls. 相似文献

Abstract The purpose of this investigation was to compare the peak physiological responses among four protocols that employed different amounts of handweighted exercise in 16 males (aged 26.3 ± 4.1 years). The four protocols were (a) uphill treadmill running (UR; 3.36 m-s1, 2.5% grade increase-3 min1); (b) uphill treadmill walking while pumping 1.36kg handweights (HW) (UWHW; 1.79ms1, 5.0% grade increase-3 min1; (c) treadmill walking while pumping .91-kg HW (WHW; 1.79 m-s1, 0% grade, .91kg HW increase-3 min1); and (d) standing in place and pumping HW (SHW; arm work as described in WHW). It was hypothesized that the peak responses would be inversely proportional to the estimated muscle mass activated (i.e., UR = UWHW > WHW > SHW). Dependent variables included peak oxygen uptake (VO2 peak), peak heart rate (HRpeak), peak ventilation (Vepeak), and peak respiratory exchange ratio (RERpeak). No differences were noted between UR and UWHW with respect to any of the dependent variables. All variables (except RERpeak) were greater (p < .01) in UR and UWHW than either WHW or SHW. RERpeak was greater (p < .01) in UR and UWHW than in WHW. VO2peak and HRpeak were greater (p < .01) in WHW when compared to SHW. Mean VO2peak was 97.5, 69.7, and 60% of UR for UWHW, WHW, and SHW, respectively. Therefore, walking and pumping handweights provides a maximal stimulus to the oxygen transport system. 相似文献

The Validity of the Tritrac-R3D Activity Monitor for the Assessment of Physical Activity in Children
Abstract The purpose of this study was to evaluate the validity of the Tritrac-R3D Activity Monitor, a new instrument designed to improve assessments of physical activity. Comparisons were made with a heart rate monitor and with a Caltrac Activity Monitor. Thirty-five children (ages 9–11 years) were monitored on 3 different school days with all 3 instruments. The Tritrac was moderately correlated with the heart rate monitor (r =.58) and highly correlated with the Caltrac monitor (r =.88). By taking advantage of the minute-by-minute timing capability of the Tritrac and the heart rate monitors, it was discovered, that the correlations between these instruments were highest during free play situations (lunch/recess, recess, after school) and were lower when activity was more limited (class time) or structured (physical education). The ability of the Tritrac to assess activity on a minute-by-minute basis may greatly enhance its overall utility. 相似文献
