Purpose: To evaluate the influence of physical maturity on the changes in ventricular morphology and function with sport training in female youth athletes.Methods: Thirty-two female athletes (age 13–18 years) underwent height and weight measurement and 2-D echocardiographic evaluation immediately prior to, and following, a 20-week soccer season. Pre- and post-season left ventricular end-diastolic diameter (LVEDD), end-diastolic volume (LVEDV), ejection fraction (LVEF), stroke volume (LVSV), mass (LVM), and posterior wall thickness (LVPWT), right ventricular end-diastolic diameter (RVEDD), end-diastolic area (RVEDA), and fractional area change (RVFAC), and interventricular septal thickness (IVST) were compared. In-season change in each variable was compared across pre-season hours of vigorous physical activity (0–1, 2–3, >3 hours).Results: Significant increases were identified in LVEDV (51.3?±?10.4?v 56.4?±?9.6?ml/m2, p?=?0.001) and RVEDA (10.5?±?1.9?v 11.3?±?2.5?cm2/m2, p?=?0.040), but not LVEDD, LVM, LVPWT, LVSV, RVEDD, RVEDA, RVFAC, or IVST (p?>?0.05 for all). In-season changes in echocardiographic variables did not differ across hours of pre-season vigorous physical activity (p?>?0.05 for all).Conclusion: Among female adolescent soccer players, in-season training elicits changes in resting ventricular volume, but not wall thickness or systolic function. These adaptations do not appear to be influenced by pre-season physical activity level. 相似文献

This paper describes a non-classical logic course primarily indicated for graduate students in electrical engineering and energy engineering. The content of this course is based on the vision that it is not enough for a student to indefinitely accumulate knowledge; it is necessary to explore all the occasions to update, deepen, and enrich that knowledge, adapting it to a complex world. Therefore, this course is not tied to theoretical formalities and tries at each moment to provide a practical view of the non-classical logic. In the real world, the inconsistencies are important and cannot be ignored because contradictory information brings relevant facts, sometimes modifying the entire result of the analysis. As consequence, the non-classical logics, such as annotated paraconsistent logic – APL, are efficiently framed in the approach of complex situations of the real world. In APL, the concepts of unknown, partial, ambiguous, and inconsistent knowledge are referred not to trivialise any system in analysis. This course presents theoretical and applicable aspects of APL, which are successfully used in decision-making structures. The course is divided into modules: Basic, 2vAPL, 3vAPL, 4vAPL, and Final Project. 相似文献

Two studies assessed whether: (1) high levels of task-relevant metacognition would be related to good task performance; (2) some kinds of feedback (e.g., explanations) would improve task-relevant metacognition (and hence, performance) more than other kinds of feedback; and (3) some kinds of people would be more likely to seek out and use this beneficial feedback than others. Results showed that: (1) students were able to better estimate their task performance with increasing experience at the task; (2) students who provided better estimates of their task success were more successful at the task; (3) students high in need for cognition sought out problem explanations more often than students low in need for cognition; but (4) students who scored high in trait metacognition did not seek out problem explanations more often than students who scored low in trait metacognition; (5) students who were high in need for cognition performed better at the task than those who were low in need for cognition, and (6) the receipt of problem explanations was only weakly related to high levels of task performance, if at all. The implications of these results are discussed. 相似文献

The advent of genomics, proteomics, and microarray technology has brought much
excitement to science, both in teaching and in learning. The public is eager to
know about the processes of life. In the present context of the explosive growth
of scientific information, a major challenge of modern cell biology is to
popularize basic concepts of structures and functions of living cells, to
introduce people to the scientific method, to stimulate inquiry, and to analyze
and synthesize concepts and paradigms. In this essay we present our experience
in mixing science and education in Brazil. For two decades we have developed
activities for the science education of teachers and undergraduate students,
using microscopy images generated by our work as cell biologists. We describe
open-air outreach education activities, games, cell modeling, and other
practical and innovative activities presented in public squares and
favelas. Especially in developing countries, science education is
important, since it may lead to an improvement in quality of life while
advancing understanding of traditional scientific ideas. We show that teaching
and research can be mutually beneficial rather than competing pursuits in
advancing these goals. 相似文献

This article presents a report of a pedagogic experience carried out in a Portuguese 6th-grade music education class during the 2008–2009 school year. A podcast was created (www.podomatic.com) and several activities were developed, in classroom context, taking advantage of the tool's potential for teaching and learning. Although the podcast was managed by the teacher, the published contents were developed mostly by the students, therefore becoming themselves producers of the information on the Web and having an active role in the construction of the global society of the 21st century. The informal learning activity was evaluated at the end of the year, using both qualitative and quantitative data collection techniques. Results show that the podcast activity involved students in the learning process, making them aware of the new roles they will play in the global information society. 相似文献

Variability analysis has been used to understand how competitive constraints shape different behaviours in team sports. In this study, we analysed and compared variability of tactical performance indices in players within complex I at two different competitive levels in volleyball. We also examined whether variability was influenced by set type and period. Eight matches from the 2012 Olympics competition and from the Portuguese national league in the 2014–2015 season were analysed (1496 rallies). Variability of setting conditions, attack zone, attack tempo and block opposition was assessed using Shannon entropy measures. Magnitude-based inferences were used to analyse the practical significance of compared values of selected variables. Results showed differences between elite and national teams for all variables, which were co-adapted to the competitive constraints of set type and set periods. Elite teams exploited system stability in setting conditions and block opposition, but greater unpredictability in zone and tempo of attack. These findings suggest that uncertainty in attacking actions was a key factor that could only be achieved with greater performance stability in other game actions. Data suggested how coaches could help setters develop the capacity to play at faster tempos, diversifying attack zones, especially at critical moments in competition. 相似文献

Contextual influences on talent development (e.g., birthplace effects) have become a topic of interest for sport scientists. Birthplace effects occur when being born in a certain city size leads to participation or performance advantages, typically for those born in smaller or mid-sized cities. The purpose of this study was to investigate birthplace effects in Portuguese volleyball players by analysing city size, as well as population density – an important but infrequently used variable. Participants included 4062 volleyball players (Mage = 33), 53.2% of whom were men. Using Portuguese national census data from 1981, we compared participants (within each sex) across five population categories. In addition, we used ANOVAs to study expertise and population density. Results indicated that men and women athletes born in districts of 200,000–399,999 were 2.4 times more likely to attain elite volleyball status, while all other districts decreased the odds of expert development. For men, being born in high-density areas resulted in less chance of achieving expertise, whereas there were no differences for women. The results suggest that athletes’ infrastructure and social structure play an important role in talent development, and that these structures are influenced by total population and population density, respectively. 相似文献

One of the most hotly debated ideas in science studies is the claim that contemporary science is in the midst of a transformation. While ‘transformationalist’ arguments and concepts vary, their core principle is that the norms, values and practices that have enforced the separation of science from society are being challenged by new expectations that scientists pursue closer connections with industry, government and/or civil society, and address research questions of immediate value to non-academic partners. While many major funding agencies have embraced this idea and now pressure scientists to enhance the ‘societal relevance’ of their work, the impact of these changes on scientific practices is still unclear. This paper reports findings from a comparative meso-level analysis of 14 large Canadian research networks funded by an agency with an explicit transformationalist mandate – the Networks of Centres of Excellence (NCE) programme. Documents and web communications from these 14 NCEs, as well as from the central programme administration office, are analysed and compared to key transformationalist concepts, such as Mode 2 science, post-normal science, the triple helix model, academic capitalism and strategic science. We find that transformationalist ideas have a strong rhetorical presence across the 14 NCE projects and the central office, but that a great deal of inconsistency and confusion exists at the level of implementation and assessment of outcomes. Easily quantifiable outputs, such as the commercialization of research findings, are favoured over softer qualitative outcomes, such as public engagement and knowledge sharing. We conclude by arguing that the NCE programme is having an observable impact on the rhetoric of science, but any resulting transformations in practice are incremental rather than radical. 相似文献

Structural equation modelling was used to test a model integrating achievement goal orientation, learning style, self-efficacy
and metacognition into a single framework that explained and predicted variation in performance. Self-efficacy was the strongest
predictor of performance. Metacognition was a weak predictor of performance. Deep processing had a weak, negative relationship
with performance. Mastery-approach goals were related to deep-processing and surface-processing learning styles. Mastery-approach
and performance-approach goals were positive predictors of self-efficacy. Mastery-avoidance and performance-avoidance goals
were related to self-efficacy. 相似文献
