To determine the validity and reliability of percent body fat estimates in 177 boys and 154 girls between 12–17 years of age, percent body fat was assessed once using dual-energy X-ray absorptiometry and twice using the sum of two skinfolds and three bioelectrical impedance analysis devices. The assessments were repeated on 79 participants on a second day. The agreement between the percent body fat estimates from the four prediction methods and dual-energy X-ray absorptiometry was evaluated using Bland–Altman analyses and a mixed linear model. All methods were reliable within and between days. The sum of two skinfolds (±6.8% body fat), OMRON (OMRON Healthcare Inc., Vernon Hills, Illinois, USA) bioelectrical impedance analysis (0 ± 7.3% body fat), and TANITA 521 (TANITA Corporation, Tokyo, Japan) bioelectrical impedance analysis (±7.6% body fat) had wide prediction intervals and are acceptable for use in large population-based studies. The TANITA 300A bioelectrical impedance analysis is not recommended for use in children and adolescents due to its wide prediction interval (±8.1% body fat) and large bias. A criterion method should be used when the accurate assessment of body composition of an individual is critical. 相似文献

Kelsey Ebben and Peter Magolda admit that using a campus Christian group as an exemplar of effective student involvement is unorthodox. But, they argue, the widely applicable lessons for other organizations are too praiseworthy to pass up. 相似文献

This experiment assessed whether instructor credibility (low or high) moderated the effects of grade incentives (rewards or punishment) and advantage framing (gain or loss) of technology policies on students’ intent to comply and motivation to learn. Results indicate that credibility increased motivation to learn. Significant moderated moderated mediation was found: a three-way interaction affected both intent to comply, and motivation to learn as mediated by attitude toward the policy. Specifically, credibility positively influenced learning outcomes via attitude when the syllabus used opposing frame-incentive structure (i.e., gain-framed punishment and loss-framed reward). 相似文献

Frontal asymmetry (FA), the difference in brain activity between the left versus right frontal areas, is thought to reflect approach versus avoidance motivation. This study (2012–2021) used functional near-infrared spectroscopy to investigate if infant (Mage = 7.63 months; N = 90; n = 48 male; n = 75 White) FA in the dorsolateral prefrontal cortex relates to psychopathology in later childhood (Mage = 62.05 months). Greater right FA to happy faces was associated with increased internalizing (η2 = .09) and externalizing (η2 = .06) problems at age 5 years. Greater right FA to both happy and fearful faces was associated with an increased likelihood of a lifetime anxiety diagnosis (R2 > .13). FA may be an informative and early-emerging marker for psychopathology. 相似文献

Studies of infant motor development in autism spectrum disorder (ASD) have increased in recent years. This article synthesized this literature through meta-analysis to assess (a) whether infant motor ability differs in ASD relative to neurotypical controls; and (b) whether motor ability and communication are related in infants with ASD. Study 1 aggregated data from 1,953 infants with ASD (ages 3.0–42.0 months), and Study 2 included 890 infants with ASD (age 6.0–42.9 months). Study 1 revealed that infant motor ability differed significantly in ASD compared with neurotypical infants—this difference was robust to variation in measurement and design. Furthermore, this group difference amplified as age increased. Study 2 indicated that within ASD, infant motor ability and communication are related. 相似文献

We collected behavioral evidence to support the hypothesis that video game conditions have varying influences on hippocampus-dependent memory. Results indicate that participants who played in the video game conditions with clear reward mechanisms performed better on a declarative memory task than those who played in the video game conditions without reward mechanisms. Those who reported spending more time gaming weekly also performed the task better than those who reported spending less time gaming weekly, suggesting that gaming might have short-term and long-term effects on the hippocampus. 相似文献

Indigenous communities practice survivance and challenge social and political systems to support their children's identity and well-being. Grounded in transformative social-emotional learning (SEL) and tribal critical race theory, this 3-year community-based participatory research study (2019–2021) examined how a SEL program co-created with an Indigenous community in Flathead Nation in Montana supports anti-racism and anti-colonialism among Indigenous children. Critical reflexivity and thematic analyses of Community Advisory Board meetings and journals written by 60 students (Mage = 10.3, SD = 1.45; 47% girls; 60% Native American) during the SEL program revealed themes on Indigenous identity, belonging, wellness, and colonialism. These results shed light on challenging the racist and colonial roots of education to support Indigenous children's survivance and social-emotional well-being. 相似文献

There is debate internationally about the production of curriculum texts and the epistemologies underpinning the knowledge legitimated in national curricula. National History curricula in particular are a source of contention bounded by calls for coherent and unifying national narratives that are inclusive and reflect the complexity of the discipline and historical consciousness of the nation to which they are bound. This paper uses critical spatial theory to highlight the ‘spaces’ and ‘places’ of the Australian Curriculum History (years 7–10) which organise and disorganise representations of identities in and out of the centre of the national narrative. Interrogating the impact of these representations within purported inclusive and cohesive national narratives draws attention to the notions of belonging presented to Australian citizens. We argue that resistance to normative national narratives and colonial legacies presented with place-based identities can reinhabit the curriculum. This reinhabiting and decentring seeks to engage History students with alternative perspectives and articulations to the national narrative, and foster meaningful connections to place and citizenship. Finally, critical place-based education approaches invite an embodied local/global citizen through local and marginalised knowledges. 相似文献
