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just restored democracy to showcase to the world a modern and pluralistic society leaving behind the authoritarian and outdated dictatorship.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

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

In this ITEMS module, we introduce the generalized deterministic inputs, noisy “and” gate (G‐DINA) model, which is a general framework for specifying, estimating, and evaluating a wide variety of cognitive diagnosis models. The module contains a nontechnical introduction to diagnostic measurement, an introductory overview of the G‐DINA model, as well as common special cases, and a review of model‐data fit evaluation practices within this framework. We use the flexible GDINA R package, which is available for free within the R environment and provides a user‐friendly graphical interface in addition to the code‐driven layer. The digital module also contains videos of worked examples, solutions to data activity questions, curated resources, a glossary, and quizzes with diagnostic feedback.  相似文献

Drawing on data from students, higher education staff and policymakers from six European countries, this article argues that it remains a relatively common assumption that students should be politically engaged. However, while students articulated a strong interest in a wide range of political issues, those working in higher education and influencing higher education policy tended to believe that students were considerably less politically active than their predecessors. Moreover, while staff and policy influencers typically conceived of political engagement in terms of collective action, articulated through common reference to the absence of a ‘student movement’ or unified student voice, students’ narratives tended not to valorise ‘student movements’ in the same way and many categorised as ‘political’ action they had taken alone and/or with a small number of other students. Alongside these broad commonalities across Europe, the article also evidences some key differences between nation-states, institutions and disciplines. In this way, it contributes to the comparative literature on young people’s political engagement specifically, as well as wider debates about the ways in which higher education students are understood.  相似文献

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

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.

In the following essay, I will discuss D.Johnson's argument in her ETHICOMP99 KeynoteSpeech (Johnson 1999) regarding the possiblefuture disappearance of computer ethics as anautonomous discipline, and I will analyze somelikely objections to Johnson's view.In the future, there are two ways in whichcomputer ethics might disappear: (1) therejection of computer ethics as an aspect ofapplied ethics, or (2) the rejection ofcomputer ethics as an autonomous discipline.The first path, it seems to me, would lead tothe death of the entire field of appliedethics, while the second path would lead onlyto the death of computer ethics as a separatesubject. Computer technology is becoming very pervasive,and each scientific field includes somediscipline-specific computing. For the likelyforeseeable future, disciplines such asbioethics and engineering ethics will have todeal with ethical issues involving the role ofcomputers. I will argue that computer ethics inthis sense is unlikely to disappear, even ifcomputer ethics ceases to be considered as aseparate discipline.In order to understand which path will befollowed by computer ethics, I will compareJohnson's argument with ideas of earlierthinkers like N. Wiener (1950) and B. Russell(1932). Although Russell did not specificallyconsider computer technology, he had somegood intuitions about the development ofsocieties by means of technology.My conclusion will be two-fold: (1) thatapplied ethics will not die, but it may make nosense in the future to talk about computerethics as a separate field; and (2) thatcomputer ethics will not simply become``ordinary ethics', contrary to Johnson's view.  相似文献
