The purpose of this study was to measure and characterise the distances covered by Brazilian professional futsal players. The trajectories of 93 players during five matches were obtained using an automatic tracking method. The distances covered were analysed for different game conditions: over the entire game and during the times when the ball was out of play and in play separately. When the entire game was considered, the results showed that there was a reduction in the total distance covered per minute from the first [median ± IQR (interquartile range): 97.9 ± 16.2 m/min] to the second half (median = 90.3 m/min; IQR = 12.0), and when only the in-play time was considered (first half: 136.6 ± 17.2 m/min; second half: 129.2 ± 16.7 m/min). The percentage of distance covered in the standing and walking velocity range was higher in the second half than in the first when considering the entire game (30.8% and 28.0%, respectively) and during the in-play time (19.3% and 16.2%, respectively). In conclusion, this study verified that futsal players reduced the physical performance during the second half. 相似文献

Teachers have been shown to frequently avoid addressing biotechnology topics. Aiming to understand the extent to which teachers’ scarce engagement in biotechnology teaching is influenced by their beliefs and/or by extrinsic constraints, such as practical limitations, this study evaluates biology teachers’ beliefs about biotechnology and biotechnology teaching. The findings of a survey administered to 93 secondary school teachers reveal that, in spite of holding positive beliefs about biotechnology, teachers overestimate the obstacles presented at biotechnology teaching, particularly concerning material and resource limitations. Implications of these findings for teacher training program design are discussed. 相似文献

An in-depth scientific survey revealed the deterioration mechanisms affecting the ‘Santa Maria della Stella’ church in Saluzzo, Italy, where various salt crystallization processes are strongly damaging the building materials and artworks. Rainwater seepage permeates the vault and interior, causing: (1) epsomite growth as interstitial columnar crystals (resulting in pictorial coating detachment) or superficial, powdery efflorescence; (2) formation of nesquehonite/hydromagnesite crusts on wall paintings; and (3) nitratine growth causing pigment staining and detachment. These processes involve selective Mg2+ mobilization from magnesian-lime mortars and bacterial-induced formation of nitrates from guano, with consequent precipitation of degrading salts. The study confirms how characterization of all deterioration agents is fundamental to planning a viable cultural heritage conservation and restoration programme. 相似文献

The field of academia is frequently associated with traditional norms that aim to regulate scholarly activity, especially research. The social web, as another field, is often viewed as challenging long-established conventions with novel knowledge production practices. Hence, the two fields seem to oppose rather than complement each other. Using a Bourdieuian lens, this research examines research participants’ accounts of their approaches to practice on the social web in relation to academia. The paper reports on the habitus dissonance between the two fields, before discussing the effects of the two fields’ competing doxas on individuals’ habitus. 相似文献

Bourdieu’s career long endeavour was to devise both theoretical and methodological tools that could apprehend and explain the social world and its mechanisms of cultural (re)production and related forms of domination. Amongst the several key concepts developed by Bourdieu, habitus has gained prominence as both a research lens and a research instrument useful to enter individuals’ trajectories and ‘histories’ of practices. While much attention has been paid to the theoretical significance of habitus, less emphasis has been placed on its methodological implications. This paper explores the application of the concept of habitus as both theory and method across two sub-fields of educational research: graduate employment and digital scholarship practices. The findings of this reflexive testing of habitus suggest that bridging the theory-method comes with its own set of challenges for the researcher; challenges which reveal the importance of taking the work of application seriously in research settings. 相似文献

This study investigates how reading achievement relates to student and school characteristics in countries with different reading scores at the fourth grade level. Data comes from the Progress in International Reading Literacy Study (PIRLS) 2011 for Denmark, Sweden, and France and the multilevel analysis includes two levels: student/home and schools. The school effectiveness and the home literacy models informed the selection of the independent variables. Results show that students’ early literacy skills, home literacy practices and resources, and reading behavior are associated with reading scores in all countries. Furthermore, across different countries there are student/home universals and school particulars that explain variation in reading achievement. Educational policies should address home and school literacy skills and practices, school climate, and school composition to improve students’ reading ability. 相似文献
