Interpersonal dynamics and relative positioning to scoring target of performers in 1 vs. 1 sub-phases of team sports

Abstract In this study, we examined the effects of relative positioning of attacker-defender dyads to the basket on interpersonal coordination tendencies in basketball. To achieve this aim, four right-hand dominant basketball players performed in a 1 vs. 1 sub-phase, at nine different playing locations relative to the basket (from 0° to 180°, in 20° increments). Performers' movement displacement trajectories were video-recorded and digitized in 162 trials. Results showed that interpersonal coordination tendencies changed according to the scaling of the relative position of performers to the basket. Stable in-phase modes of coordination were observed between performers' longitudinal and lateral displacements (50.47% and 43.02%) on the left side of the court. On the right side of the court, a shift in the dominant mode of coordination was observed to a defender lead-lag of -30°, both for longitudinal and lateral displacements (30.51% and 32.65%). These results suggest how information about dribbler hand dominance and relative position to the basket may have constrained attacker-defender coordination tendencies in 1 vs. 1 sub-phases of basketball.  相似文献   

PolarityRank: Finding an equilibrium between followers and contraries in a network     

Fermín L. Cruz  Carlos G. VallejoFernando Enrı´quez  José A. Troyano 《Information processing & management》2012

In this paper we present the relevance ranking algorithm named PolarityRank. This algorithm is inspired in PageRank, the webpage relevance calculus method used by Google, and generalizes it to deal with graphs having not only positive but also negative weighted arcs. Besides the definition of our algorithm, this paper includes the algebraic justification, the convergence demonstration and an empirical study in which PolarityRank is applied to two unrelated tasks where a graph with positive and negative weights can be built: the calculation of word semantic orientation and instance selection from a learning dataset.  相似文献   

How to conduct research on the inherent moral significance of teaching: A phenomenological elaboration of the standard repertory grid application     

Carlos A. van Kan  Petra Ponte  Nico Verloop 《Teaching and Teacher Education》2010,26(8):1553-1562

George Kelly’s repertory grid application seems a promising method for researching the moral significance of teaching from a ‘life world’ perspective. However, we encountered several challenges employing the repertory grid in its standard form for an inquiry into the inherent moral significance of teachers’ everyday classroom interactions. In this article we will set out in detail how, on the basis of the standard repertory grid application, we developed a repertory interview method that can be used to collect data that could foster a thorough understanding of the inherent moral significance of teachers’ day-to-day classroom interactions.  相似文献   

Interoperability and Information Integration in an Early Online Academic Digital Library of Theses and Dissertations: The Case of BTD     

Roberto Carlos dos Santos Pacheco  Vinícius Medina Kern  Paulo Henrique S. Bermejo 《International Information and Library Review》2003,35(2-4):319

Cooperative organization has been proposed as a means to improve the usefulness of virtual libraries. Information interchange among library and other academic applications is often hindered by the lack of application interoperability. This hindrance may be overcome through the development of standards that allow for digital libraries to exchange and share information with other applications. The Graduate Program in Production Engineering (PPGEP) of the Federal University of Santa Catarina (UFSC) launched its Theses and Dissertations Bank (BTD) in 1995. BTD is possibly the first online academic digital library of theses. From a digital document repository, BTD evolved into a system that combines bibliometry and informetry features. BTD is used by students and faculty in their research activities, but also by decision makers from industry and academia. They use it, respectively, to search for specialists and to measure interest and knowledge interchange among PPGEP research areas. This article presents the history, features, and development prospects for the BTD project. The integration of BTD with other academic applications, especially those of the Brazilian national science and technology platform, is emphasized.  相似文献

Creation of reusable open textbooks: Insights from the Connexions repository          下载免费PDF全文

Carlos Rodriguez‐Solano  Salvador Sánchez‐Alonso  Miguel‐Angel Sicilia 《British journal of educational technology : journal of the Council for Educational Technology》2015,46(6):1223-1235

Open textbook initiatives have appeared as an alternative to traditional publishing. These initiatives for the production of alternatively copyrighted educational resources provide a way of sharing materials through the Web. While the open model of peer‐produced materials enables the global reuse of textbooks, the combination of fragments to produce new textbooks tailored to particular needs is not easy. The heterogeneity of topics and target audiences, as well as the cultural and institutional differences of educational systems across the globe, raises the need for new compositional features, fostering—at the same time—the reuse of the newly produced combinations. This paper reviews the current models of reuse and sharing, and presents a quantitative analysis of the Connexions repository which provides evidence about the culture of reuse in open textbook initiatives.  相似文献   

Homework and academic achievement across Spanish Compulsory Education     

José Carlos Núñez  Natalia Suárez  Rebeca Cerezo  Julio González-Pienda  Pedro Rosário  Rosa Mourão 《教育心理学》2015,35(6):726-746

Homework (HW) is one of the most common school-related activities among parents, students and teachers. However, the need to assign HW to students has been extensively debated. The present investigation examines the relationship between specific HW variables (i.e. amount of HW completed, time spent on HW and perceived quality of HW time management) and academic achievement, while controlling for students’ gender and grade level. Participants included 454 students (ranging from 10 to 16?years of age) from three schools in northern Spain. A multivariate analyses of variance and path analyses showed that the amount of HW completed decreased with increased schooling, as did students’ perceived quality of HW time management. Data from hierarchical regression analyses completed by path analyses provided evidence that time spent on HW conjointly with perceived quality of HW time management explains how academic achievement is mediated by the amount of HW completed. These findings deepen the understanding of the complex impact of time spent on HW and on academic achievement.  相似文献
