Abstract

The aim was to evaluate the effects of judo combat on the athletes’ postural control (PC) and physiological loading before, during and after a simulated match. Seventeen under-20 regional and national level athletes completed one modified 7-min match. At baseline, during the combat (3rd and 7th minutes) and 2-min post-match centre of pressure (CoP) parameters were assessed. Heart rate (HR), blood lactate (BLa) and rating of perceived exertion (RPE) and local RPE (LRPE) were collected. Significant increments were observed in CoP mean positioning and velocity at 3rd and 7th minutes, but the CoP deviation in both axes was unaffected. HR and BLa were elevated at 3rd and 7th minutes, and they remained elevated 2-min post-match. However, CoP returned to baseline 2-min post-match. RPE was elevated at 3rd and 7th minutes and the greatest effort was displayed in the Deltoid and Quadriceps. Thus, one simulated judo match stimulates a significant metabolic response and balance is degraded, with the greatest effects on the anterior–posterior axis and it recovers to baseline level after 2 min of passive rest. The physiological load cannot be regarded as a potential predictor variable of CoP. Overall, a judo match predominantly affects the upper body than the other body parts.  相似文献   

An experimental study of constrained clustering effectiveness in presence of erroneous constraints     

M. Eduardo Ares  Javier Parapar  Álvaro Barreiro 《Information processing & management》2012

Recently a new fashion of semi-supervised clustering algorithms, coined as constrained clustering, has emerged. These new algorithms can incorporate some a priori domain knowledge to the clustering process, allowing the user to guide the method. The vast majority of studies about the effectiveness of these approaches have been performed using information, in the form of constraints, which was totally accurate. This would be the ideal case, but such a situation will be impossible in most realistic settings, due to errors in the constraint creation process, misjudgements of the user, inconsistent information, etc. Hence, the robustness of the constrained clustering algorithms when dealing with erroneous constraints is bound to play an important role in their final effectiveness.  相似文献   

Protecting Copyright Through Semantic Technology     

Javier Prenafeta 《Publishing Research Quarterly》2010,26(4):249-254

As regulatory actions against copyright infringement have become to a large degree ineffective in the global context of Internet, new solutions balancing the interests of copyright owners, users and intermediaries were required. Semantic technology applied to Copyright may be considered an alternative to DRM or TPM systems, as metadata can be associated with a work, its title, author or right holder and intellectual property rights involved, so combining query languages and applications, the use or diffusion of those contents over the Internet can be controlled (authorizing or denying them) in what we named “Semantic Copyright”.  相似文献   

Parents’ response to a Facebook group in secondary education. Preliminary data     

Javier Bernabé-Martín 《Technology, Pedagogy and Education》2020,29(2):203-217

ABSTRACT

Social networks are explored as educational tools, but results remain contradictory. The goal was to assess families’ response to a Facebook group created to support class work and expand it to homes. Forty parents (27 mothers, 13 fathers) participated. A pre-experimental one-group post-test-only research design was followed. The group’s activity was analysed using Gytrics, while interviews were conducted with parents. Quantitative results showed that the group had a significant impact: a high percentage joined the group, its reach was 100% (all participated), there were 15,875 visits, 502 publications (103 made by parents), 2823 reactions, Tuesdays and Thursdays were the most active days and 21:00–22:00 the most active hours. Qualitative results showed six themes: change in the perception of the subject, novel experience, interesting/positive, learning community, safe environment and reasons to join. The use of Facebook to support class work had a positive impact on parents, connecting school and family.  相似文献   

The Impact of Tourette’s Syndrome in the School and the Family: Perspectives from Three Stakeholder Groups     

Jesús Rivera-Navarro  Esther Cubo  Javier Almazán 《International journal for the advancement of counseling》2014,36(1):96-113

This article analyzes the perceptions of Spanish health professionals, children with Tourette’s Syndrome (TS) and their parents about social, school and family problems related to the disorder. A qualitative research methodology was used involving Focus Groups (FGs) made up of children with TS (× 2 FGs), parents/caregivers of persons with TS (× 2 FGs) and health professionals (× 1 FG). The study highlights many of the principal areas of concern for persons with TS, parents/caregivers and health professionals that directly and indirectly add to the burden of living with the disorder. The results of the study point out that the stigma and social maladjustment in children with TS is caused in large part by a misunderstanding of the disorder by teachers and peers. Parents of children with TS especially emphasize tics, considering them to be the main cause of social maladaptation. The results suggest that interventions among parents, teachers and peers should be implemented towards a greater understanding of the disorder and its symptoms.  相似文献   

Functioning of the attentional networks at rest vs. during acute bouts of aerobic exercise     

Huertas F  Zahonero J  Sanabria D  Lupiáñez J 《运动与训练心理学杂志》2011,33(5):649-665

The present study explored the effects of three different activity conditions on three attentional functions: alerting, orienting, and executive control. A group of highly experienced cyclists performed the Attention Network Test-Interactions (Callejas, Lupiá?ez, & Tudela, 2004) at rest, during moderate aerobic exercise, and during intense aerobic exercise. Results indicated that aerobic exercise accelerated reaction time and reduced the alerting effect compared with the rest condition. However, aerobic exercise did not modulate the functioning of either the orienting or the executive control attentional networks. No differences in reaction time or attentional functioning were observed between the two aerobic exercise workloads. The present results suggest that moderate aerobic exercise modulates the functioning of phasic alertness by increasing the general state of tonic vigilance.  相似文献   

When arts and crafts education meets Fascism: the Friuli mosaic school, 1922-1943     

Simone Battiston  Javier P. Grossutti 《History of education》2013,42(6):751-768

This paper examines the early history of the Friuli Mosaic School (FMS), an Italian arts and crafts school specialising in mosaic and terrazzo. The history of the FMS opens up a rare window into an often-overlooked field in the history of education: arts and crafts schools in Fascist Italy (1922–1943). Then, the FMS excelled in mosaic education and production and gained the trust of the regime, which notably commissioned the school to produce large mosaic works for the Foro Italico sports complex in Rome. Yet, as this paper contends, the FMS–Fascist Italy relationship was primarily functional rather than political. Similarly, the FMS adopted a pragmatic approach in times of economic hardship by becoming an active agent for its students and alumni who were compelled to emigrate. The migrant trajectory of alumnus Ettore Lorenzini to the United States was paradigmatic of this.  相似文献   

The Effect of External Representations on Compare Word Problems: Supporting Mental Model Construction     

David Múñez  Josetxu Orrantia  Javier Rosales 《Journal of Experimental Education》2013,81(3):337-355

This study explored the effectiveness of external representations presented together with compare word problems, and whether such effectiveness was moderated by working memory. Participants were 49 secondary school students. Each participant solved 48 problems presented in 4 presentation types that included 2 difficulty treatments (number of steps and language consistency). Data from errors and response times indicated that adding a graph to compare word problems helped accuracy (d =.60) and response time (d =.44). This effect was larger for difficult and cognitively demanding problems. Findings suggest that external representations might help problem-solvers build a mental model of the described problem situation. In addition, working memory was not found to moderate the effectiveness of external representations.  相似文献
