BackgroundAthletes tend to have better visuo-motor performance than do sedentary individuals. However, several basic visual-function and perceptual parameters remain unexplored to date. In this study, we investigated whether differences exist in visual function, performance, and processing between basketball players and individuals without a sport-involvement background.MethodsA total of 33 healthy men with no visual impairment or pathology were divided into 2 groups, depending on the involvement in sport (semi-professional basketball players and sedentary individuals). We tested their baseline heart-rate variability in the resting position apart from subjective questionnaires to determine their physical fitness level, and we checked their visual function, performance, and processing through an extended battery of optometric tests.ResultsThe 2 groups differed in resting heart-rate variability parameters (p < 0.001), confirming their dissimilarities in regular time practising sports per week. The basketball players showed a closer breakpoint and recovery nearpoint of convergence, a higher fusional-vergence rate, better discriminability halos, and better eye–hand coordination (all p values < 0.05).ConclusionThese results show evidence that athletes, basketball players in this case, exhibit better performance in several visual abilities in comparison to a group of individuals without sporting backgrounds, suggesting an improvement due to the systematic involvement of those skills during basketball practice.  相似文献   

1982 FIFA World Cup: from Spain’s struggle for democratic legitimacy to Italy’s rediscovery of football nationalism     

Juan Antonio Simón 《Soccer & Society》2019,20(7-8):948-959

ABSTRACT

One of the most memorable moments in the World Cups history is Marco Tardelli’s second goal in Italy’s win over Germany in the 1982 World Cup finals. Better known as Tardelli’s scream, it is thus a perfect object to analyse in order to understand football’s deeper social meanings and its political and cultural undertones, in this case both for the World Cup champions, Italy, and for the host country, Spain. In the Spanish case, organizing the World Cup was a huge political opportunity for the just restored democracy to showcase to the world a modern and pluralistic society leaving behind the authoritarian and outdated dictatorship. As for Italy, their first World Cup winning since World War II was heavily politically used by actors across the political spectrum. Such nationalistic approach constituted a novelty after decades of a low profile national discourse.  相似文献

Classroom to Communities of Practice: Benefits for English Learners and Teacher Candidates Through Partnerships     

Michele Regalla  Alex Davies  Donita Grissom  Antonio Losavio 《Multicultural Perspectives》2018,20(1):25-32

This study investigates a service-learning program for university students seeking teacher certification examined through the lens of sociocultural theory. Data was collected from teacher candidates (TCs) in the form of surveys and an open-ended writing assignment. Administrators from the partner schools were also interviewed to provide their perspectives of the service learning. Findings show that the service-learning program allowed TCs and their English learners (ELs) to form communities of practice that were mutually beneficial. Teacher candidates reported numerous opportunities to apply the strategies learned in their methods course, as well as an increase in their sense of preparation for teaching ELs. Administrators provided positive feedback about the service-learning program in terms of the relationship between the partner school and the university. Difficulties arose in terms of TCs' accountability and the level of participation afforded to the TCs by the classroom teacher. Implications highlight the importance of negotiating expectations that address the needs of both parties equally in order to support a strong community of practice that prepares TCs to meet the needs of ELs.  相似文献   

The media construction of the sports’ elite from the European perspective: an analysis of the European Symposium of Sports 2010     

David Moscoso Sánchez  Antonio Pérez Flores 《Sport in Society》2018,21(3):516-528

Since the first Olympic Games, the figure of the athlete has roused enormous passion. One may wonder if nowadays the cultural mechanisms that produce them are analogous and perform the same functions as in the past. This article aims to answer these questions. For this purpose, we have relied on the analysis of the discourse from different actors in the 2010 European Symposium of Sports “Thinking Sports, Transforming Society: The EU in favor of citizenship for the XXI Century”. The results will provide relevant information about the responsibility of the mass media in the production of a sports spectacle, the role of the big brands and the exemplarity of the sports’ elite. In this manner, the need was conveyed of producing a different view of sports, so that in the contest between humanistic values and materialistic values, those who contribute to the welfare of the citizens could achieve glory.  相似文献

Towards Covid-19 Literacy     

Archila  Pablo Antonio  Danies  Giovanna  Molina  Jorge  Truscott de Mejía  Anne-Marie  Restrepo  Silvia 《Science & Education》2021,30(4):785-808

Covid-19 literacy, induced by the coronavirus disease (2019), is characterized as the understanding of Covid-19 as well as informed decisions based upon this understanding. This type of literacy is closely related to health literacy, scientific literacy, and scientific media literacy. It may be obvious to say that Covid-19 literacy is a key factor for governments to effectively manage the Covid-19 transition. However, lack of literature exists about Covid-19 literacy among university students. Therefore, the current study aimed to determine the Covid-19 literacy level among 4168 students from a Colombian university. The data were derived from students’ responses to a 25–item anonymous online self-reporting questionnaire. We found that 21–25-year age group, graduate students,?students enrolled prior to 2015, and medical students had a significantly higher mean score. Moreover, the Internet (86.8%) was the most popular source of information from which participants gained most information regarding Covid-19. Furthermore, 58.5% of the participants considered health workers as a source that can provide accurate information. Most importantly, the findings reveal the students’ knowledge about (1) the role of an eventual process of vaccination, (2) the test currently used as diagnostic for Covid-19, and (3) the fatality rate, three aspects of Covid-19 literacy that deserve more attention. The findings provide a useful basis for the formulation of policies and concrete actions in improving Covid-19 literacy.

The Nature of Scientific Practice and Science Education     

Antonio García-Carmona  José Antonio Acevedo-Díaz 《Science & Education》2018,27(5-6):435-455

There is, broadly speaking, an agreement within the international science education community that comprehension of the nature of science (NOS) should be a key element in the scientific literacy of citizens. During the last few decades, several didactic approaches have emerged concerning what and how to teach NOS. Also, one of the basic objectives of science education is for students to become familiar with the skills typical of scientific practice; however, there is little reference to their need to also acquire meta-knowledge about scientific practice (i.e., an understanding of the nature of scientific practice). Among other reasons, this may be due to NOS being essentially identified in most of the predominant proposals with the nature of scientific knowledge. But why not plan the teaching of science to be in tune with real scientific practice for students to learn about the nature of scientific practice at the same time as they are learning science? The answer to this question has given rise to a proposal grounded in ten essential pedagogical principles for the teaching and learning of science in secondary school. These are the principle of formulating questions, the principle of creativity and imagination, the principle of experimentation, the principle of procedural diversity, the principle of errors as opportunity, the principle of modeling, the principle of cooperation and teamwork, the principle of argumentation and discussion, the principle of communication, and the principle of evaluation. The purpose of this article is to present the justification and fundaments of these principles.  相似文献   

Free operant avoidance behavior in hooded rats: IRTs and response chains     

Della M. Hann  A. E. Roberts 《Learning & behavior》1984,12(2):175-183

Twenty-five hooded rats were given 50 avoidance training sessions with leverpress IRTs obtained during as well as between sessions. Five qualitatively different shapes to the IRT profiles were found: single- or double-peaked shapes, positively or negatively accelerated shapes, and U-shaped distributions. Both the specific shape of the profile and the stability of that shape during a session were related to the avoidance proficiency of an individual rat. Six rats received two additional training sessions, with the final 30 min of each videotaped to obtain frequency counts of nine behavior categories. The observational data showed that avoidance-proficient rats typically incorporated the leverpress requirement into repetitive response chains.  相似文献   

Pedro Gutiérrez Bueno’s Textbooks: Audiences, Teaching Practices and Chemical Revolution     

José Ramón Bertomeu Sánchez  Antonio García Belmar 《Science & Education》2006,15(7-8):693-712

Pedro Gutiérrez Bueno wrote two editions of a chemistry textbook between 1788 and 1802. The paper offers a comparative view of both editions taking into account Gutiérrez Bueno’s biography, his intended audience and the changes related to the so-called chemical revolution. Some conclusions are at odds with common images about scientific revolutions and the role of textbooks in science. The analysis aims to shed some light on the multiple historical forces shaping textbooks and the way in which scientific change is assimilated by their writers.
