A landmark-based statistical method, morphological variation analysis, for the quantification of the repeatability in the arrangement of body segments during the execution of sport actions has recently been developed. A two-dimensional shape is produced and its morphology is studied. The method was used to measure the within-team variability of the relative positions of players during the execution of offensive schemes in soccer. Two junior soccer teams of different technical abilities (semi-professional vs. amateur), each playing two standardized offensive schemes of different difficulty (easier: throw-in; more difficult: wing attack) were filmed. Each scheme was repeated 25 (semi-professionals) or 10 (amateurs) times. For each repetition, the position of the players in a single significant frame was analysed using morphological variation analysis. The reproducibility of both schemes was higher among the semi-professionals than among the amateurs (two-way analysis of variance, P<0.005). The repeatability of the players' relative positions was related to the difficulty of the scheme and the technical level of the team. Among the amateurs, the throw-in was more reproducible than the wing attack (Student's t-test, P<0.005). The method not only allows the quantification of collective (team) coordination, but also the separation of the influence of individual players. 相似文献

The reflection provoked by RDA produced the awareness that the flat format of MARC 21 records is inadequate in expressing the relationships between bibliographic entities that the FRBR model and RDA standard consider fundamental. RIMMF and BIBFRAME indicate to software developers a way to think that is consistent with RDA. In Italy, @Cult, a software house and bibliographic agency working for Casalini Libri, has taken on the charge of following and facilitating the transition: OliSuite/WeCat provides an implementation of RDA that integrates vocabularies and ontologies already present in the Web by structuring the information in linked open data. 相似文献

Football can play different roles in the lives of immigrant youth. It can be a site for leisure, sport performance and socialization. Even more critically, it can be a place where to negotiate sense of belonging to a local community and to gain access to national sporting cultures. Football can also represent forms of exclusion and discrimination. This article aims to elucidate the meanings that participation in football hold for black immigrant males in a country of recent immigration such as the Republic of Ireland. The article discusses the findings of a long-term ethnographic study with a youth team based in a working-class area of Dublin, the Irish capital. The youth football club plays a special role as a term of identification for the local community. Teenage players of different African backgrounds are presented with the challenge of acquiring different levels of inclusion. They can attempt to appropriate cultural codes that define local working-class men on and off the pitch or they can practice forms of ‘resistance’ that emphasize their own racialized positioning in Irish society. Overall, these dynamics affirm the importance of grassroots football as a venue for young people’s transcultural encounters. 相似文献

Formal thought organization obtained from free speech, a key feature for psychiatric evaluations, has been poorly investigated during typical development. Computational tools such as speech graph connectedness (LSC) currently allow for an accurate quantification in naturalistic settings. LSC's typical development is better predicted by years of education than by age. Among beginning readers, the LSC of stories composed of short‐term memory predicted reading independently from IQ. Here we set out to test a longitudinal sample (6–8 years old, n = 45, followed for 2 years) to verify whether the LSC is predictive of various memory measures, and whether such relations can explain the correlation with reading. The LSC was specifically correlated with verbal short‐term memory performance. The results support the notion that the short‐term storage of verbal information is necessary to plan a story. Given the limited sample size, the relationship of this interaction with reading remains inconclusive. 相似文献

Several studies demonstrate that Sport Education supports the development of an authentic experience of sport. Social media has the potential to further the development of an authentic sport experience since it is a key aspect of contemporary sport culture and can be a space for individuals to interact during the Sport Education. Yet the evidence-base on the use of social media within Sport Education is limited. The purpose of this study was to explore how social media supports the development of an authentic sport experience within Sport Education. The context of this study was within a female recreational community sport futsal club. Players engaged with Sport Education as a focus for their sessions for 13 weeks. The Sport Education season embedded the six key features. During the Sport Education season, players interacted with each other through Facebook. Data were generated from; (1) researcher/player field journal, (2) Facebook posts and (3) post-season player interviews. Data analysis involved inductive, constant comparison and member-checking methods. Results showed that players’ uses of Facebook supported the development of an authentic sport experience. Players’ uses of Facebook strengthened the development of three key Sport Education features; affiliation, festivity and season. Based on the limited amount of research on the impact of social media within Sport Education and community sport, future studies should continue to examine the effectiveness of social media as an interactional tool to enhance the development of an authentic sport experience. 相似文献
