Childhood sport participation is argued to be important to understand differences in self-regulation and performance level in adolescence. This study sought to investigate if football-specific activities in childhood (6–12 years of age) is related to self-regulatory skills and national under 14- and 15-team selection in Norwegian elite youth football. Data of practice histories and self-regulatory skills of 515 youth football players selected at Norwegian regional level were collected and further analysed using multilevel analyses. The results revealed that high self-regulated players were more likely to be selected for national initiatives, and increased their involvement in peer-led football practice and adult-led football practice during childhood, compared to players with lower levels of self-regulation. While national level players reported higher levels of peer-led football play in childhood, the interaction effect suggest that the regional level players increased their involvement in peer-led play during childhood compared to national level players. In conclusion, the findings indicate that childhood sport participation may contribute to later differences in self-regulation, and highlights the importance of childhood engagement in football-specific play and practice in the development of Norwegian youth football players. 相似文献

AbstractThis paper provides an overview of a collection of works related to sport and Christianity from historical perspectives. After a brief general historiographical introduction, the material connected to the burgeoning field of sport and religion is summarized. In particular, it is noted that the works concentrate on diverse geographic locations and different time periods. The investigations are not limited to a narrow definition of Christianity, but encompass a wide range of denominations, related philosophies, and viewpoints. In terms of variety, it is noted that different methodological and theoretical approaches are adopted, and, given the existing state of play, it is clear that there is still much to be uncovered, documented, and written about when it comes to the enduring topic of sport and Christianity. The conclusion is that any research agenda which emerges from observations on historical perspectives concerning the relationship of sport with aspects of Christianity will continue to resonate and add value to wider understandings of sport, culture, and the human condition. 相似文献

The article presents an analysis of the effect of granularity and order in an XML encoded collection of full text journal articles. Two-hundred and eighteen sessions of searchers performing simulated work tasks in the collection have been analysed. The results show that searchers prefer to use smaller sections of the article as their source of information. In interaction sessions during which articles are assessed, however, they are to a large degree evaluated as more important than the articles’ sections and subsections. 相似文献

Problem-solving by everyday individuals is thought to occur as a two-step process. First, an individual identifies or formulates a problem, followed by entering into a subsequent search to find the best solution. Here, however, we consider an alternative process that everyday individuals may use for solution finding first theorized by von Hippel and von Krogh (2016). Specifically, von Hippel and von Krogh proposed that everyday individuals may sometimes discover a solution and the need it satisfies simultaneously without the need for apriori problem formation, a cognitive process they called “need-solution pair recognition”. Utilizing a rich literature from psychology and neuroscience, we propose that seemingly spontaneous discoveries found by need-solution pair recognition are natural products of the object recognition system and its underlying mechanisms. This view asserts that on encountering an object and reasoning how it might be used (i.e. functional object understanding), an individual's perception of an object may culminate in recognizing the object as a solution, and in some cases, as a solution to a problem previously unknown to him or her, thus bypassing formal problem-formulation and active solution searching entirely. To empirically test this view, we manipulated the ability of everyday individuals to functionally reason about objects while we examined the spontaneous occurrence of solutions found by either need-solution pair recognition or traditional problem-first problem-solving. Consistent with our hypothesized mechanism, our results indicate that need-solution pair recognition occurs more frequently when constraints on functional object understanding are reduced. That is, we found that needsolution pair discoveries outpaced solutions found from traditional problem solving, in environments with unfamiliar objects, where participants were not directed to solve specific problems. Our results provide clear evidence that everyday individuals in the household sector do not always innovate through traditional problem-solving processes, but instead may arrive at solutions as they recognize and reason about objects. Implications for research and practice in household innovation, and for innovation more generally are considered. 相似文献

The hypothesis that the concept of expectancy is a central common core of various personality dispositions was investigated among 228 students of general education and physical education. The participants were scored on the following personality dispositions: global and academic self-concept, optimistic-pessimistic attributional style, motive to seek success, motive to avoid failure, cognitive anxiety, and self-handicapping tendencies. Marital status and geographical location/area of study of respondents were chosen as discriminative variables. The hypothesis was supported in that factor analysis gave a general bipolar expectancy factor, and cluster analysis resulted in two clusters, one corresponding to a positive expectancy and the other to a negative expectancy. 相似文献

The purpose of the study was to explore the relationship between attribution and selected personality dispositions, as well as self‐serving attribution. Four hypotheses were formulated: (1) Attributions for positive events correlate differently with the five personality dispositions than attributions for negative events, (2) factor analysis and cluster analysis of attributions for positive and negative events and the five personality dispositions will generate a general bipolar expectancy factor, (3) self‐serving attributions will dominate irrespective of subcultural context, and (4) the dominance of self‐serving attributions will be stronger in an individualistic‐oriented context than in a collectivistic‐oriented context. One‐hundred‐and‐fifty students, selected from two educational contexts (one individualistic‐oriented and one collectivistic‐oriented), were scored on attributions for positive and negative events as well as on the five personality dispositions on the basis of an inventory. All four hypotheses were supported. Educational implications are discussed. 相似文献

In this paper, we analyse the gender differences between the educational performance of 15-year-old children of migrants from specific regions of origin countries living in different destination countries with the Programme for International Student Assessment (PISA) 2009 wave. We study whether this gender difference of migrant pupils deviates from the gender difference between the native pupils in their destination country. We analyse the educational performance of 16,612 daughters and 16,804 sons of migrants in destination countries across Asia, Europe, Latin America, and Oceania. We distinguish 62 origin countries and 12 origin areas in 30 destination countries. Female migrant pupils have both higher reading and math scores than comparable male migrant pupils, and these gender differences among migrant pupils are larger than among comparable native pupils. Parental socioeconomic background has an equal effect on the educational performance of daughters of migrants and on that of sons of migrants. The variation in educational performance by region of origin is, however, not clearly related to the poverty or traditionalism of regions. 相似文献
