ABSTRACTBackground: The FIFA 11+ has shown positive effects on balance and proprioception parameters in football players. As there have been very few research studies involving futsal, we examined the short and long term effects of the FIFA 11+ on static and dynamic balance, as well as proprioception in male amateur futsal players.Methods: Seventy-one male futsal players were randomized to two groups (FIFA 11+: n = 37, age: 27.33 ± 4.33 years; Control: n = 34, age: 25.55 ± 4.65 years). Intervention lasted 10 weeks, 2 sessions per week, succeeded by a 10-week follow-up period. For balance testing, we assessed the single-legged postural sway with a force platform (static balance) and the Y balance test (dynamic balance). Proprioception was assessed with active joint position sense testing.Results: Complete pre-post intervention and follow-up tests were available for 61 players. The FIFA 11+ group showed higher training exposure and lower body mass index and body weight. After adjustment for baseline differences, no significant differences between groups were observed in the pre-post changes for centre of pressure measures, Y-balance and proprioception parameters both at short and long-term.Conclusions: Performing FIFA 11+ for 10 weeks did not improve static and dynamic balance as well as proprioception in amateur futsal players. 相似文献

This article aims to shed light on the current debate regarding the role of internships in higher education in graduates’ employability. In specific, it analyses empirical data on a large-scale study of Portuguese first-cycle study programmes, in order to explore indicators of the professional value of internships in the employability of higher education graduates. Results demonstrate that study programmes that include internships tend to significantly enhance graduates’ employability, particularly within the universe of polytechnic and public higher education institutions. Besides the instrumental value of internships, the impact of the nature and structure of the internship on the percentage of unemployed graduates are also discussed. Mandatory internships and the inclusion of multiple, shorter internships throughout the degree are negatively associated with unemployment levels. Results indicate work-based learning can be used as a successful strategy to bridge theoretical knowledge and practice and enhance graduate employability. These findings provide important insights for the evaluation and/or the design of internship programmes in higher education. 相似文献

Our work is based on the study of learning strategies used by a group of trainee teachers in a real learning situation, and how this use of strategies influences the results of the learning process. We use a diary as a tool to assess the learning strategies and compare the results obtained with those using an inventory. Our findings indicate that the deliberate use of strategies (measured by diaries) has a positive effect on knowledge acquisition, with the qualitative analysis method of the verbal protocols noted in the diaries proving more valuable than the use of traditional inventories. 相似文献

ABSTRACTFamily is widely regarded as a cornerstone of student support. When family support exist as an essential form of social capital making, rupture of family ties places students in a disadvantageous position. This paper focuses on estranged students’ accounts of their experiences of higher education, highlighting how capital dynamics shape their academic trajectories. Based on interviews with 21 estranged students, our research uncovers different dimensions of estranged students’ struggles and successes as they move through academia. This paper explores the social imagination that surrounds the university student, or ‘student experience’, as resting upon family support. The authors propose that widening participation policies and practices need to be more attuned to the realities that mark estranged students’ experiences, as they are not only impacted by the scarcity of either economic or social capital, but also by the instability of interrelated capitals that contribute to precarious and volatile experiences. 相似文献

A new method is proposed for clustering XML documents by structure-constrained phrases. It is implemented by three machine-learning approaches previously unexplored in the XML domain, namely non-negative matrix (tri-)factorization, co-clustering and automatic transactional clustering. A novel class of XML features approximately captures structure-constrained phrases as n-grams contextualized by root-to-leaf paths. Experiments over real-world benchmark XML corpora show that the effectiveness of the three approaches improves with contextualized n-grams of suitable length. This confirms the validity of the devised method from multiple clustering perspectives. Two approaches overcome in effectiveness several state-of-the-art competitors. The scalability of the three approaches is investigated, too. 相似文献

Fifteen years looking at the mirror: On the presence of PISA in education policy processes (Portugal, 2000‐2016) 下载免费PDF全文
Luís Miguel Carvalho Estela Costa Catarina Gonçalves 《European Journal of Education》2017,52(2):154-166
This article describes and discusses what happens when knowledge for policy generated within PISA is received by its target audience: what have the Portuguese policy actors been doing with PISA data and analysis when they consider, express and justify their choices? Drawing on previous and current studies, using interview materials and formal and informal policy documents, as well as texts published in the written press, the article analyses two main phenomena related to the reception of PISA and how this has evolved between 2001 and 2012 in Portugal: the consolidation of PISA's credibility as a source for policy processes and texts; the emergence of new actors and modes of intervention in the production of knowledge for national policy, drawing on PISA. Finally, it presents an analysis of the reception of PISA 2015 in the Portuguese media, focusing on the interventions by political actors in the Portuguese daily and weekly written press. Two main elements emerge from our content analysis as the main common elements of that reception: the consecration of PISA's credibility; and the practices of qualification and disqualification of educational policies and perspectives. The article concludes by emphasising the regulatory role of PISA in Portuguese policy processes and the relevant contribution played by the politics of reception in legitimising this role. 相似文献

The primary purpose of this study was to examine several key questions related to the neuropsychological contributors to early
written language. First, can we develop an empirical measurement model that encompasses many of the neuropsychological components
that have been deemed as important to the development of written language? Second, once derived, will the neuropsychological
components of this model remain stable over first and second grades or will the model change in its composition? Third, will
the strength of the relationships between neuropsychological components and writing outcomes be constant over time, or will
the strength of the relationships change over time? Finally, will the derived empirical model show significant concurrent
and predictive relationships with written expression? The sample included 205 first grade students recruited from a single
school district who were followed into the second grade via two cohorts: Measures were aligned with major neuropsychological
components as extracted from theoretical models of written expression and available empirical findings examining the neuropsychological
contributors to writing in children. These domains included fine-motor speed, language, short-term memory, long-term memory,
and various attention/executive functions including working memory. Confirmatory factor analyses (CFAs) and longitudinal structural
equation modeling (SEM) methods documented that three core latent traits were present and stable at both grades 1 and 2: Fine-Motor,
Language, and Attention/Executive Functions. The overall model was highly related to written expression and spelling at both
grades 1 and 2, with the first grade latent traits accounting for 52 and 55% of the variance in second grade written expression
and spelling, respectively. At both grades, the Language and Attention/Executive Functions latent traits were more highly
associated with written expression and spelling than the Fine-Motor latent trait. 相似文献
