Fetal heart rate and variability: stability and prediction to developmental outcomes in early childhood     

DiPietro JA  Bornstein MH  Hahn CS  Costigan K  Achy-Brou A 《Child development》2007,78(6):1788-1798

Stability in cardiac indicators before birth and their utility in predicting variation in postnatal development were examined. Fetal heart rate and variability were measured longitudinally from 20 through 38 weeks gestation (n = 137) and again at age 2 (n = 79). Significant within-individual stability during the prenatal period and into childhood was demonstrated. Fetal heart rate variability at or after 28 weeks gestation and steeper developmental trajectories were significantly associated with mental and psychomotor development at 2 years (n = 82) and language ability at 2.5 years (n = 61). These data suggest that the foundations of individual differences in autonomic control originate during gestation and the developmental momentum of the fetal period continues after birth.  相似文献

Rapid Prototyping a Collections-based Mobile Wayfinding Application     

Jim Hahn  Alaina Morales 《The Journal of Academic Librarianship》2011,37(5):416-422

This research presents the results of a project that investigated how students use a library developed mobile app to locate books in the library. The study employed a methodology of formative evaluation so that the development of the mobile app would be informed by user preferences for next generation wayfinding systems. A key finding is the importance of gathering ongoing user feedback for designing useful and used mobile academic library applications. Elements and data points to include in future mobile interfaces are discussed.  相似文献   

The Representation of Altruistic and Egoistic Motivations in Children’s TV Programming     

Ron Tamborini  Lindsay Hahn  Brian Klebig  Clare Grall 《Communication Research Reports》2017,34(1):58-67

A content analysis of children’s television examined the frequency with which behaviors were (a) driven by altruistic versus egoistic motivations, (b) performed by affable/surly characters, (c) rewarded/punished, and (d) present in content popular among different age groups (2–5, 6–11, and 12–17 years old). We found that portrayal patterns stressed the importance of egoistic motivations (particularly competence, autonomy, and relatedness) for older children. The findings are interpreted in line with logic underlying the model of intuitive morality and exemplars (MIME; Tamborini, 2013), suggesting that media representations can influence the motivations of their viewers.  相似文献   

讲座制下德国大学教师的职业发展     

孔捷  马蒂亚斯·韩  迟芳 《外国教育研究》2010,(1)

讲座是德国大学的重要学术组织形式,讲座制是德国高等教育体制的重要特征。在高等教育体制高度趋同的德国,大学教师的职业发展模式体现了这种制度的本质和核心,教师的聘用、晋升和任命是构成这种模式的关键因素。在教育大众化和全球化发展背景下,传统体制弊端日益显现,改革迫在眉睫。  相似文献   

A protocol for measuring the direct effect of cycling on neuromuscular control of running in triathletes

Abstract

The direct effects of cycling on movement and muscle recruitment patterns (neuromuscular control) during running are unknown but critical to success in triathlon. We outline and test a new protocol for investigating the direct influence of cycling on neuromuscular control during running. Leg movement (three-dimensional kinematics) and muscle recruitment (surface electromyography, EMG) were compared between a control run (no prior exercise) and a 30-min transition run that was preceded by 20 min of cycling. We conducted three experiments investigating: (a) the repeatability (between-day reliability) of the protocol; (b) the ability of the protocol to investigate, in highly trained national or international triathletes, the direct influence of cycling on neuromuscular control during running independent of neuromuscular fatigue; and (c) the ability of the protocol to provide a control, or baseline, measure of neuromuscular control (determined using a measure of stability) without causing fatigue. Kinematic and EMG measures of neuromuscular control during running showed moderate to high repeatability: mean coefficients of multiple correlation for repeatability of EMG and kinematics were 0.816 ± 0.014 and 0.911 ± 0.031, respectively. The protocol provided a robust baseline measure of neuromuscular control during running without causing neuromuscular fatigue (coefficients of multiple correlation for stability of EMG and kinematics were 0.827 ± 0.023 and 0.862 ± 0.054), while EMG and force data provided no evidence of fatigue. The protocol outlined here is repeatable and can be used to measure any direct influence of cycling on neuromuscular control during running.  相似文献   

Stability of Core Language Skill from Early Childhood to Adolescence: A Latent Variable Approach     

Marc H. Bornstein  Chun‐Shin Hahn  Diane L. Putnick  Joan T. D. Suwalsky 《Child development》2014,85(4):1346-1356

This four‐wave prospective longitudinal study evaluated stability of language in 324 children from early childhood to adolescence. Structural equation modeling supported loadings of multiple age‐appropriate multisource measures of child language on single‐factor core language skills at 20 months and 4, 10, and 14 years. Large stability coefficients (standardized indirect effect = .46) were obtained between language latent variables from early childhood to adolescence even when accounting for child nonverbal intelligence and social competence and maternal verbal intelligence, education, speech, and social desirability. Stability coefficients were similar for girls and boys. Stability of core language skill was stronger from 4 to 10 to 14 years than from 20 months to 4 years, so early intervention to improve lagging language is recommended.  相似文献
