A multilevel hypernetworks approach to capture meso-level synchronisation processes in football

ABSTRACT

Understanding team behaviours in sports performance requires understanding the interdependencies established between their levels of complexity (micro-meso-macro). Previously, most studies examined interactions emerging at micro- and macro-levels, thus neglecting those emerging at a meso-level (reveals connections between player and team levels, depicted by the emergence of coordination in specific sub-groups of players–simplices during performance). We addressed this issue using the multilevel hypernetworks approach, adopting a cluster-phase method, to record player-simplice synchronies in two performance conditions where the number, size and location of goals were manipulated (first-condition: 6 × 6 + 4 mini-goals; second-condition: Gk + 6 × 6 + Gk). We investigated meso-level coordination tendencies, as a function of ball-possession (attacking/defending), field-direction (longitudinal/lateral) and teams (Team A/Team B). Generally, large synergistic relations and more stable patterns were observed in the longitudinal direction of the field than the lateral direction for both teams, and for both game phases in the first condition. The second condition displayed higher synchronies and more stable patterns in the lateral direction than the longitudinal plane for both teams, and for both game phases. Results suggest: (i) usefulness of hypernetworks in assessing synchronisation of teams at a meso-level; (ii) coaches may consider manipulating these task constraints to develop levels of local synchronies within teams.  相似文献

Peer effects and measurement error: The impact of sampling variation in school survey data (evidence from PISA)     

John Micklewright  Sylke V. Schnepf  Pedro N. Silva 《Economics of Education Review》2012

Investigation of peer effects on achievement with sample survey data on schools may mean that only a random sample of the population of peers is observed for each individual. This generates measurement error in peer variables similar in form to the textbook case of errors-in-variables, resulting in the estimated peer group effects in an OLS regression model being biased towards zero. We investigate the problem using survey data for England from the Programme for International Student Assessment (PISA) linked to administrative microdata recording information for each PISA sample member's entire year cohort. We calculate a peer group measure based on these complete data and compare its use with a variable based on peers in just the PISA sample. We also use a Monte Carlo experiment to show how the extent of the attenuation bias rises as peer sample size falls. On average, the estimated peer effect is biased downwards by about one third when drawing a sample of peers of the size implied by the PISA survey design.  相似文献   

Adolescent's Physical Activity: Association with Socio‐Economic Status and Parental Participation Among a Portuguese Sample     

Jorge Mota  Guiomar Silva 《Sport, Education and Society》2013,18(2):193-199

ABSTRACT

Although the health effects of physical activity during adolescence have been studied less frequently, physical activity seems to have a positive influence on some health concerns in adolescence. Moreover, few studies have reported consistently the relationship between parents’ socio‐economic status (SES) and physical activity habits and adolescents’ activities. Significant physical activity gender differences were reported (p ≤ 0.001). No evidence was found regarding the influence of socio‐economic status on adolescents’ self‐reported physical activity. Mothers (r= 0.23; p ≤ 0.0001) and fathers (r= 0.16; p ≤ 0.05) seem to have a significant influence on adolescents’ physical activity.  相似文献   

The Impact of High School Science Teachers’ Beliefs,Curricular Enactments and Experience on Student Learning During an Inquiry-based Urban Ecology Curriculum     

Katherine L. McNeill  Diane Silva Pimentel  Eric G. Strauss 《International Journal of Science Education》2013,35(15):2608-2644

Inquiry-based curricula are an essential tool for reforming science education yet the role of the teacher is often overlooked in terms of the impact of the curriculum on student achievement. Our research focuses on 22 teachers’ use of a year-long high school urban ecology curriculum and how teachers’ self-efficacy, instructional practices, curricular enactments and previous experience impacted student learning. Data sources included teacher belief surveys, teacher enactment surveys, a student multiple-choice assessment focused on defining and identifying science concepts and a student open-ended assessment focused on scientific inquiry. Results from the two hierarchical linear models indicate that there was significant variation between teachers in terms of student achievement. For the multiple-choice assessment, teachers who spent a larger percentage of time on group work and a smaller percentage of time lecturing had greater student learning. For the open-ended assessment, teachers who reported a higher frequency of students engaging in argument and sharing ideas had greater student learning while teachers who adapted the curriculum more had lower student learning. These results suggest the importance of supporting the active role of students in instruction, emphasising argumentation, and considering the types of adaptations teachers make to curriculum.  相似文献   

The Development of Science Education Research in Brazil and Contributions from the History and Philosophy of Science     

Alberto Villani  Valeria Silva Dias  Juarez Melgaco Valadares 《International Journal of Science Education》2013,35(7):907-937

Over the last 50 years a new research area, science education research, has arisen and undergone singular development worldwide. In the specific case of Brazil, research in science education first appeared systematically 40 years ago, as a consequence of an overall renovation in the field of science education. This evolution was also related to the political events taking place in the country. We will use the theoretical work of Rene Kaës on the development of groups and institutions as a basis for our discussion of the most important aspects that have helped the area of science education research develop into an institution and kept it operating as such. The growth of this area of research can be divided into three phases: The first was related to its beginning and early configurations; the second consisted of a process of consolidation of this institution; and the third consists of more recent developments, characterised by a multiplicity of research lines and corresponding challenges to be faced. In particular, we will analyse the special contributions to this study gleaned from the field known as the history and philosophy of science.  相似文献   

Connection,Restructuring, and Buffering: How Groups Link Individuals and Organizations     

Deborah Silva 《Journal of Applied Communication Research》2013,41(2):145-166

Research examining the individual–organization relationship has largely ignored the linking role of groups. Grounded in Scott, Corman, and Cheney's (1998) structurational model of organizational identification, we analyzed data obtained from members of groups embedded in a large religious organization. Results revealed three primary ways groups link individual members and the organization via identification. The connection function provides members with local copresent linkages to the organization and an environment in which to express their connection/relationship to the organization. The restructuring function enables members to restructure conflicting individual and organizational identity structures. The buffering function enables members to disidentify with a portion of the organizational identity and still maintain a sense of organizational identification.  相似文献   

Resilience does not predict academic performance in gross anatomy     

Rodrigo Enrique Elizondo‐Omaña  María de los Angeles García‐Rodríguez  José Miguel Hinojosa‐Amaya  Eliud Enrique Villarreal‐Silva  Rosa Ivette Guzmán Avilan  Juan José Bazaldúa Cruz  Santos Guzmán‐López 《Anatomical sciences education》2010,3(4):168-173

Few studies have evaluated resilience in an academic environment as it relates to academic success or failure. This work sought to assess resilience in regular and remedial students of gross anatomy during the first and second semesters of medical school and to correlate this personal trait with academic performance. Two groups of students were compared: the first group included first‐year medical students in the regular course, and the second group included first‐year medical students who did not pass the regular anatomy course and so were enrolled in the remedial course. Both groups completed anonymous surveys designed to gather demographic data and establish scores on the Connor‐Davidson resilience scale, which includes 25 statements rated zero to four on a Likert scale (maximum score 100). The average resilience score was the same for both groups, 80 ± 9. The average anatomy grades differed significantly between regular students (67± 15.0) and remedial students (61 ± 12.0). While there was no overall correlation between resilience score and anatomy grade, regular students with resilience scores of 75 or greater showed slightly better academic performance than their classmates. Similarly, remedial students with resilience scores of 87 or greater faired better academically. Resilience does not predict academic performance in gross anatomy, and further work is necessary to identify those intrinsic and extrinsic factors that influence students' achievements.

Teaching skills to promote clinical reasoning in early basic science courses     

Rodrigo Enrique Elizondo‐Omaña  Jesus Alberto Morales‐Gómez  Orlando Morquecho‐Espinoza  José Miguel Hinojosa‐Amaya  Eliud Enrique Villarreal‐Silva  Maria de los Angeles García‐Rodríguez  Santos Guzmán‐López 《Anatomical sciences education》2010,3(5):267-271

Basic and superior reasoning skills are woven into the clinical reasoning process just as they are used to solve any problem. As clinical reasoning is the central competence of medical education, development of these reasoning skills should occur throughout the undergraduate medical curriculum. The authors describe here a method of teaching reasoning skills in a clinical context during a human anatomy course. Anat Sci Educ 3:267–271, 2010. © 2010 American Association of Anatomists.  相似文献
