The relationships among fundamental motor skills, health-related physical fitness, and body fatness in South Korean adolescents with mental retardation     

Foley JT  Harvey S  Chun HJ  Kim SY 《Research quarterly for exercise and sport》2008,79(2):149-157

The purpose of this study was to examine the following: (a) the relationships among the latent constructs of fundamental motor skills (FMS), health-related physical fitness (HRF), and observed body fatness in South Korean adolescents with mental retardation (MR); (b) the indirect effect of fundamental motor skills on body fatness when mediated by health-related fitness; and (c) whether the degree of MR and gender affects these relationships. Students ages 13 to 18 years (287 boys and 134 girls) were recruited for the study. Separate structural equation models were estimated based on gender and the level of disability: mild or moderate MR. Group differences in the model structure were not found, so the data were combined and a single model estimated. The results showed that FMS significantly contributed to HRF (standardized effects beta = .53), p < .01 and indirectly contributed to decreased body fatness mediated by HRF (-.27), p < .01. HRF directly contributed to decreased fatness (-.50), p < .01. The results from this study support the importance of both increased FMS and increased HRF in relation to decreased body fatness.  相似文献   

Motivation for Educational Attainment in Grade 9 Predicts High School Completion     

Stephen G. West  Jan N. Hughes  Han Joe Kim  Shelby S. Bauer 《Educational Measurement》2019,38(2):27-40

The Motivation for Educational Attainment (MEA) questionnaire, developed to assess facets related to early adolescents’ motivation to complete high school, has a bifactor structure with a large general factor and three smaller orthogonal specific factors (teacher expectations, peer aspirations, value of education). This prospective validity study investigated the utility of each factor in predicting high school dropout or completion of a general education development (GED) certificate versus completion of a high school degree. Participants were 474 (55.1% male) ethnically diverse students who were originally recruited into a larger longitudinal study in Grade 1 on the basis of academic risk. Fourteen years later, 373 had obtained a high school diploma, 15 had obtained a GED, and 86 had dropped out of high school. During their first year of Grade 9, participants were administered the MEA. Using multinomial logistic regression with high school graduation as the reference outcome and controlling for Grade 9 letter grades, reading and math test scores, gender, and ethnic/racial group status, scores on the latent general factor and the latent peer aspirations factor predicted high school dropout versus high school graduation status. Neither the general factor nor any of the three specific factors predicted GED completion versus high school graduation. Ethnicity, but not gender, moderated the associations between scores on the general factor and high school graduation versus dropout.  相似文献   

Linguistic and Cultural Variation in Early Color Word Learning     

Samuel H. Forbes  Kim Plunkett 《Child development》2020,91(1):28-42

When and how do infants learn color words? It is generally supposed that color words are learned late and with a great deal of difficulty. By examining infant language surveys in British English and 11 other languages, this study shows that color word learning occurs earlier than has been previously suggested and that the order of acquisition of color words is similar in related languages. This study also demonstrates that frequency and syllabic complexity can be used to predict variability in infant color word learning across languages. In light of recent evidence indicating that color categories have universal biological foundations, these findings suggest that infants’ experience and linguistic exposure drive their shift to culturally and linguistically mediated adult-like understandings of color words.  相似文献   

Service Blueprinting: A Method for Assessing Library Technologies within an Interconnected Service Ecosystem     

Scott W. H. Young  Sara Mannheimer  Doralyn Rossmann  David Swedman  Justin D. Shanks 《Public Library Quarterly》2020,39(3):190-211

ABSTRACT

Service blueprinting is a method for designing, assessing, and improving services. This article provides a practical overview of the service blueprinting process for library technology services. We begin by outlining the recent conversation around library technologies, service design, and service blueprinting. We then detail an iterative case study for the creation process of a service blueprint, followed by a discussion of the service insights and improvements that resulted from this activity. We conclude by offering a set of recommendations for creating and analyzing service blueprints. Ultimately, the service blueprint is a useful tool for understanding the operation of a service, and for situating that service within a broader and interconnected library ecosystem.  相似文献   

Comparison of children’s free-living physical activity derived from wrist and hip raw accelerations during the segmented week     

Robert J. Noonan  Lynne M. Boddy  Youngwon Kim  Zoe R. Knowles  Stuart J. Fairclough 《Journal of sports sciences》2017,35(21):2067-2072

This study assessed children’s physical activity (PA) levels derived from wrist-worn GENEActiv and hip-worn ActiGraph GT3X+ accelerometers and examined the comparability of PA levels between the two devices throughout the segmented week. One hundred and twenty-nine 9–10-year-old children (79 girls) wore a GENEActiv (GAwrist) and ActiGraph GT3X+ (AGhip) accelerometer on the left wrist and right hip, respectively, for 7 days. Mean minutes of light PA (LPA) and moderate-to-vigorous PA (MVPA) per weekday (whole-day, before-school, school and after-school) and weekend day (whole-day, morning and afternoon–evening) segments were calculated, and expressed as percentage of segment time. Repeated measures analysis of variance examined differences in LPA and MVPA between GAwrist and AGhip for each time segment. Bland–Altman plots assessed between-device agreement for LPA and MVPA for whole weekday and whole weekend day segments. Correlations between GAwrist and AGhip were weak for LPA (r = 0.18–0.28), but strong for MVPA (r = 0.80–0.86). LPA and MVPA levels during all weekday and weekend day segments were significantly higher for GAwrist than AGhip (p < 0.001). The largest inter-device percent difference of 26% was observed in LPA during the school day segment. Our data suggest that correction factors are needed to improve raw PA level comparability between GAwrist and AGhip.  相似文献   

London 2012 – Site for Political Animosities: South Korea and Japan in Confrontational Rational ‘Irrationality’ (Part One: Long Memories)     

J.A. Mangan  Bang-Chool Kim 《国际体育史杂志》2013,30(15):1784-1795

Sport and politics have a close relationship. Political conflicts are re-enacted, reflected and reinforced on international sports stages. In East Asia, the past casts a long shadow! It darkened the London 2012 stage. Controversy followed a South Korean football player's celebration at the London Olympics semi-final match between South Korea and Japan. The International Olympic Committee (IOC) banned the player, Park, Jong-woo, from participating in the bronze medal ceremony. He was accused by the IOC of a political act that violated IOC and FIFA regulations. Park's celebration included holding up and carrying around a sign which was interpreted by the IOC as a political message about a South Korean territorial dispute with Japan. The incident became a lead story in the South Korean media. The IOC's decision caused intense nationwide indignation and an outpouring of anti-Japanese sentiment. It was not a unique incident. This essay examines media representations of the incident and how political controversies between South Korea and Japan are reproduced, intensified and exacerbated by media reporting of international sports events. In South Korea, insult was added to injury by the fact that IOC's disapproval of Park's behaviour was contrasted in the South Korean media and by the public with the IOC's silence regarding the Japanese gymnastics team's uniform emblazoned with the ‘Rising Sun’ flag. The evidence from the incident is clear. Mega-sports events can be inflammatory occasions for the expression of hostile and heated political expression. Nowhere is this more the case than in East Asia with its long history of fierce national animosities and memories of national hostilities and humiliations. Throughout East Asia, international sport has become a potent medium for perpetuating painful memories!  相似文献   

A Comparison of Responsive Interventions on Kindergarteners’ Early Reading Achievement     

Mary E. Little  D’Ann Rawlinson  Deborah C. Simmons  Minjung Kim  Oi‐man Kwok  Shanna Hagan‐Burke  Leslie E. Simmons  Melissa Fogarty  Eric Oslund  Michael D. Coyne 《Learning disabilities research & practice》2012,27(4):189-202

This study compared the effects of Tier 2 reading interventions that operated in response‐to‐intervention contexts. Kindergarten children (N = 90) who were identified as at risk for reading difficulties were stratified by school and randomly assigned to receive (a) Early Reading Intervention (ERI; Pearson/Scott Foresman, 2004) modified in response to student performance or (b) their schools’ typical supplemental reading intervention (regrouping and curriculum pacing adjustments). In both conditions, intervention was provided 30 minutes per day in small groups for approximately 100 sessions. Results indicated no statistically significant group differences on any outcome measures. Between‐group effect sizes revealed substantively important differences (Valentine & Cooper, 2003) favoring the ERI responsive condition on multiple measures with effect sizes ranging from .35 to .59. Overall, findings indicated that the majority of students in both Tier 2 intervention conditions performed above the 30th percentile on posttest measures of word reading measures.  相似文献   

Correcting Biased Cohen’s Kappa in NVivo     

Sang-Yeon Kim  Scott S. Graham  Seokhoon Ahn  Michele K. Olson  Daniel J. Card  Molly M. Kessler 《Communication methods and measures》2016,10(4):217-232

This study demonstrates that NVivo, a popular research tool for content analysis, produces biased Cohen’s kappa as it calculates the reliability statistic at the character level, which is unsuitable for most content-analytic studies adopting a higher unit of analysis (e.g., sentence, paragraph). Based on empirical data and a statistical simulation, this study proposes a method of bias correction applicable to situations where two independent raters conduct binary coding.  相似文献

Multiple time scales in single input-single output high gain feedback systems     

Kar-Keung D. Young 《Journal of The Franklin Institute》1978,306(4):293-301

The asymptotic behaviour of single input-single output high gain feedback systems as the loop gain tends to infinity is investigated by singular perturbation methods. It is found that this class of feedback systems may have different time scales depending on system structure. A decomposition of the computation of the closed loop eigenvalues into two lower order problems is presented. An illustrative example is given.  相似文献
