The ‘invention’ of FIFA history: João Havelange’s election to FIFA presidency as a historic event     

Luiz Guilherme Burlamaqui 《Soccer & Society》2019,20(7-8):1056-1070

ABSTRACT

In 1974, the Brazilian sports official João Havelange was elected FIFA’s president in a two-round election, defeating the incumbent Stanley Rous. The upset, often attributed to a successful alliance with Asia, the Middle East and Africa, what at the time was referred to as the Third World – surprised observers everywhere. Here, the election can be analysed as a historically relevant event of social significance. It can be thought of as a political window by means of which the international dynamic of a specific moment in the Cold War can be perceived, especially the limitations and potentialities of the agency available to periphery countries at that time. In this article, I intend to discuss the narratives that forged the history of FIFA, which take this political ‘event’ as a key in the institution’s own historical transformation. The sources analysed will be mainly FIFA official histories, such as the FIFA News, FIFA historical books and movies about the history of FIFA.  相似文献   

Correlation analysis of performance measures for multi-label classification     

Rafael B. Pereira  Alexandre Plastino  Bianca Zadrozny  Luiz H.C. Merschmann 《Information processing & management》2018,54(3):359-369

In many important application domains, such as text categorization, scene classification, biomolecular analysis and medical diagnosis, examples are naturally associated with more than one class label, giving rise to multi-label classification problems. This fact has led, in recent years, to a substantial amount of research in multi-label classification. In order to evaluate and compare multi-label classifiers, researchers have adapted evaluation measures from the single-label paradigm, like Precision and Recall; and also have developed many different measures specifically for the multi-label paradigm, like Hamming Loss and Subset Accuracy. However, these evaluation measures have been used arbitrarily in multi-label classification experiments, without an objective analysis of correlation or bias. This can lead to misleading conclusions, as the experimental results may appear to favor a specific behavior depending on the subset of measures chosen. Also, as different papers in the area currently employ distinct subsets of measures, it is difficult to compare results across papers. In this work, we provide a thorough analysis of multi-label evaluation measures, and we give concrete suggestions for researchers to make an informed decision when choosing evaluation measures for multi-label classification.  相似文献

ABSTRACT

The aims of this study were to perform the cross-cultural adaptation of the Borg Rating of Perceived Exertion (RPE) 6–20 Scale to Brazilian Portuguese language and to start testing its validity and reliability. After performing the cross-cultural adaptation of the Scale, concurrent and discriminative validity, and reliability were determined on a treadmill in young (18–30 years) and older adult women (60–75 years). Considering young and older adult women, RPE presented high and moderate positive correlation with heart rate and high and low positive correlation with oxygen consumption, respectively. Older adult women presented RPE (11 ± 2) significantly higher than young ones (8 ± 1) exercising at the same absolute intensity. Intraclass coefficient correlation was excellent for RPE to young and older adult women. The Scale presented concurrent validity only to young adult women, whereas it presented discriminative validity between such groups of women. Moreover, the scale is reliable to young and older adult women.  相似文献

Evaluating the Effectiveness of Physlet-Based Materials in Supporting Conceptual Learning About Electricity     

Simon Ülen  Ivan Gerlič  Mitja Slavinec  Robert Repnik 《Journal of Science Education and Technology》2017,26(2):151-160

To provide a good understanding of many abstract concepts in the field of electricity above that of their students is often a major challenge for secondary school teachers. Many educational researchers promote conceptual learning as a teaching approach that can help teachers to achieve this goal. In this paper, we present Physlet-based materials for supporting conceptual learning about electricity. To conduct research into the effectiveness of these materials, we designed two different physics courses: one group of students, the experimental group, was taught using Physlet-based materials and the second group of students, the control group, was taught using expository instruction without using Physlets. After completion of the teaching, we assessed students’ thinking skills and analysed the materials with an independent t test, multiple regression analyses and one-way analysis of covariance. The test scores were significantly higher in the experimental group than in the control group (p < 0.05). The results of this study confirmed the effectiveness of conceptual learning about electricity with the help of Physlet-based materials.  相似文献
