This study assessed the associations between these factors in a random sample of Czech families with preschool and school-aged children. A nationally representative sample comprised 185 families with preschool children and 649 families with school-aged children (dyads; both parents and child n?=?365, mother and child n?=?730, and father and child n?=?469). The participants wore Yamax Digiwalker SW-200 pedometers at least four weekdays and both weekend days and completed family logbooks (anthropometric parameters, daily step counts (SC), and screen time (ST)). When a parent (fathers at weekends and mothers both on weekdays and at weekends) achieved 10,000 SC per day, their children were also significantly (OR?=?2.93–6.06, 95% CI?=?2.02–9.26) more likely to meet the daily SC recommendation. On the contrary, the involvement of fathers in organized leisure-time PA reduced their children's odds of meeting the SC recommendation on weekdays (OR?=?0.53, 95% CI?=?0.31–0.89) and at weekends (OR?=?0.41, 95% CI?=?0.24–0.72). The excessive ST of parents at weekends reduced the odds of their children meeting the SC recommendation (mother–child dyads: OR?=?0.44, 95% CI?=?0.26–0.72; father–child dyads: OR?=?0.63, 95% CI?=?0.37–1.06). High levels of parents’ PA contribute to the achievement of the recommended daily PA in children on weekdays and at weekends. Excessive weekend ST of parents reduces their odds of their children achieving the recommended daily PA; however, the influence of parents’ PA on their children’s achieving the recommended daily PA is stronger than the inhibitory effect of ST. 相似文献

After the re-establishment of independent Estonian statehood in 1991, Russian lost its privileges as the dominant and official language in Estonia, and Estonian continued as the only official language. This paper attempts to map the position of a Russian-speaking teacher within the sociological categories of power and language, based on the analysis of legislative acts and strategic documents within the domain of language policy and language legitimization practices in historical retrospective. The main focus of the study stresses an attempt to elaborate on to what extent the low self-efficacy of Russian-speaking teachers as the agents of legitimization of the Estonian language in Russian-speaking schools, and their low position in power relations within the Estonian education system, can be explained in the categories of power and language, as conceptualized on the basis of the social theory of Bourdieu. 相似文献

A variety of causes are responsible for a lack in promoting movement in German nursing homes. In this regard, research on resources holds the promise of a lasting capacity to act and should therefore be understood as a paradigm of gerontology of sports. The purpose of this paper is to make a contribution to theoretically and conceptually based approaches for operationalizing resources that promote motor abilities. Methodologically, different instruments are demonstrated that are able to assess the theoretical constructs “movement acitivity” and “influencing factors” as a basis for the subsequent analysis. Finally, a model that identifies resources is presented. It focuses on different personal and environmental factors as well as their interdependencies influencing the movement activity. The model analyzes resources and barriers to everyday movements. In this way, fundamental theoretical points of reference for research activity are shown. 相似文献

Two instructional experiments used randomized, controlled designs to evaluate the effectiveness of writing instruction for
students with carefully diagnosed dyslexia, which is both an oral reading and writing disorder, characterized by impaired
word decoding, reading, and spelling. In Study 1 (4th to 6th grade sample and 7th to 9th grade sample), students were randomly
assigned to orthographic or morphological spelling treatment but all students were taught strategies for planning, writing,
and reviewing/revising narrative and expository texts. Both treatments resulted in improvement on three measures of spelling
and one measure of composition. Morphological treatment resulted in better improvement in spelling pseudowords, whereas orthographic
treatment resulted in better improvement in rate of reading pseudowords. In Study 2 (4th to 6th grade sample), students were
randomly assigned to explicit language treatment (phonological working memory + phonological-orthographic spelling + science
report writing training) or nonverbal problem solving treatment (virtual reality-based computer simulation, drawing maps,
and building clay models). Both treatments used science content material and resulted in significant improvement in spelling
and reading pseudowords (accuracy and rate). The surprising finding was that hands-on, engaging science problem solving led
to more improvement in phonological working memory than did specialized phonological instruction. Only when spelling instruction
emphasized orthography or morphology (Study 1) did real word spelling improve.

This essay stems from the 35th annual C. H. McCloy Research Lecture at the 2015 SHAPE America National Convention &; Expo in Seattle, WA. The lecture series has 2 main aims. First, it provides an annual forum for a contemporary scholar to delve deeply into her/his work and to share that work with her/his peers. Second, it is an enduring tribute to the pioneering work and influential career of Charles Henry McCloy (March 30, 1886–September 18, 1959), research professor emeritus at the University of Iowa. This essay is composed of 6 sections: a prologue, a biography of McCloy, my autobiography, the fundamental premises and overarching aims of my work, a summary of my research contributions aimed at promoting inclusive physical activity, and an epilogue. The entire article is built around the construct of maps, mechanics, detours, and traveling companions. Paradigm shifts and insights are unraveled as the work unfolds and becomes increasingly integrated. Rarely does a scholar have the chance to provide a narrative of this nature, and it is hoped that this essay will inspire others to discover their own scholarly pathways and to contextualize and reflect on their contributions for the greater good of the field of kinesiology and society. 相似文献

Nowadays, the significance of linguistic analysis applied to cross-cultural communication is enormous due to the heterogeneity of societies and the increasingly cross-cultural nature of commerce, politics, education etc. The application of linguistic theory, therefore, means the study of sociocultural communication since analysing the pragmatics of intercultural communication is the analysis of language itself. By observing the range of aspects of communication that can vary from culture to culture, we will exemplify levels of difference in habits and expectations in signalling how speakers mean what they say. 相似文献

After explicit spelling instruction, low achieving second grade spellers increased the number of correctly spelled words during composing but differed in response trajectories. Class 1 (low initial and slow growth) had the lowest initial performance and improved at a relatively slow rate. Class 2 (high initial and fast growth) started higher than Class 1 but below Class 3 and improved at the fastest rate. Class 3 (highest initial but slow growth) had the highest initial performance but improved at a rate similar to Class 1. Class 3 differed from Classes 1 and 2 on orthographic coding. Classes 1, 2, and 3 differed on rapid automatic naming (RAN letters). Spelling instruction plus supplementary activities to improve orthographic coding in working memory and rapid, automatic coordination of phonological and orthographic codes may facilitate transfer of spelling learned during instruction to applying that spelling knowledge during independent composing. 相似文献

The protective effects of physical activity and fitness on cardiovascular health have clearly been shown among normally developed children. However, data are currently lacking pertaining to children with developmental coordination disorder (DCD). The purpose of this study was to examine differences in fitness measures, body composition, and physical activity among children with and without DCD. A cross-sectional design was implemented examining 261 children (118 girls, 143 boys) ages 4–12 years (mean age 7.8 ± 1.9 years). Children were categorized as having DCD if they scored less than or equal to the 5th percentile (n = 71) or between the 6th and the 15th percentile (n = 52) on the Movement Assessment Battery for Children (MABC; Henderson & Sugden, 1992). The typically developing children had scores between the 16th and the 50th percentile (n = 106) or above the 50th percentile (n = 32) on the MABC. The age-related body mass index was used to characterize body composition. Physical fitness was assessed with a 6-min run, 20-m sprint, jump-and-reach test, medicine ball throw, curl-ups, and sit-and-reach test. Physical activity was estimated with a questionnaire. The percentage of overweight and obese children ages 10–12 years were significantly higher in the DCD groups (severe: 50%, moderate: 23.1%) than in the typically developing groups (medium: 5.6%, high: 0%; p < .05). Significant interactions (MABC x Age Group) were found for the fitness tests (p values < .05), except flexibility; whereby specifically, compared to the children in the typically developing groups children in the DCD groups ages 4–6 years achieved significantly worse results for the 20-m sprint, and children of the DCD groups ages 10–12 years achieved significantly worse results for the 6-min run, jump-and-reach test, and medicine ball throw. The study demonstrates poorer performance in fitness tests with high demands on coordination in children with DCD compared to their typically developing peers. Furthermore, the differences in fitness increased with age between children in the DCD groups versus the typically developing groups. 相似文献
