Training and psychosocial patterns during the early development of Portuguese national team athletes     

André Barreiros  Jean Côté  António Manuel Fonseca 《High Ability Studies》2013,24(1):49-61

This study explored the early development of expert athletes compared to a group of athletes that did not achieve an expert level of performance despite being involved in youth events with their national squads. In particular, the activities, training patterns, and psychosocial influences that characterized their paths in competitive sports were examined. Male and female participants (N?=?42) from different sports were interviewed. Overall, athletes showed several commonalities. However, experts were selected to national squads later and also started thinking about investing in becoming elite athletes later. Non-experts revealed more parental pressure and less individual training with coaches.  相似文献   

Orthography and the development of metalinguistic reflection in Portuguese primary school pupils / Ortografía y desarrollo de la reflexión metalingüística en alumnos portugueses en primaria     

Otília C. Sousa  José-António Costa  Marie Nadeau 《Cultura y Educación》2013,25(4):868-878

Abstract

Linguistic awareness is crucial in learning literacy. This project has a two-fold aim: to develop the students’ ability to think about language in order to write with accuracy and to lead teachers to promote students’ discussions about their writing difficulties. The study is part of a two-year action-research project developed in primary schools from the Lisbon area, with experimental and control groups. The starting point of the project was the analysis of the problems students of third and fourth grades showed in their writing. The scope of the project includes dictation tasks within an interactionist approach, favouring grammatical discussions leading to the observation and manipulation of linguistic data.  相似文献

Building typologies identification to support risk mitigation at the urban scale – Case study of the old city centre of Seixal,Portugal     

Cátia Santos  Tiago Miguel Ferreira  Romeu Vicente  J.A. Raimundo Mendes da Silva 《Journal of Cultural Heritage》2013,14(6):449-463

The old urban centres are marks of an historical and architectural heritage that should be protected and safeguarded. For such, it is fundamental to have a complete understanding of the genesis, regarding both building and the urban mesh. This fact is essential to the support of qualified, conscientious and sustainable rehabilitation interventions on the old building stock. The research carried out addresses the issue of the old urban centres from the perspective of the analysis and inventory of buildings features. The cataloguing process of the building typologies is presented in this work as a synthesis of the principal construction forms, with the old city centre of Seixal being used as a case study. The identification of building typologies has supported a seismic and fire vulnerability assessment of the old building stock. The assessment methodologies developed and used are based on the detailed survey and building inspection, therefore the building typology cataloguing is essential in the analysis at such a large scale. Then we discussed the strategy for the conservation actions incorporated in a broader risk management policy.  相似文献   

Should digital files be considered a commons? Copyright infringement in the eyes of lawyers     

Jérôme Hergueux 《The Information Society》2019,35(4):198-215

In this article, we draw on a survey conducted with elite upcoming lawyers from all around the world to shed new light on the ethical acceptability of file sharing practices. Although file sharing is typically illegal, our findings show that lawyers overwhelmingly perceive it as an acceptable social practice. The main criterion used by lawyers to decide on the ethical acceptability of file sharing is whether or not the infringer derives any monetary benefits from it. Further, our findings show that lawyers in the public sector (including judiciary and academia) are even more tolerant of online copyright infringement than those in the private sector. Interestingly, our data suggests that this is largely the result of self-selection: lawyers who lean more on the side of broad disclosure and social sharing tend to orient themselves toward the public sector. Implications for the current state of the debate on the reform of copyright law are discussed.  相似文献   

Twenty-four-hour movement behaviours and fundamental movement skills in preschool children: A compositional and isotemporal substitution analysis     

Jéssica Gomes Mota  Cain Craig Truman Clark  Luís Lemos  Cézane Priscilla Reuter  Jorge Augusto Pinto Silva Mota 《Journal of sports sciences》2020,38(18):2071-2079

ABSTRACT

Studies that have analysed the association between the different movement behaviours and fundamental movement skills (FMS) have considered it in an independent manner, disregarding the compositional nature of 24-h movement behaviours (24-h MB). The aim of this study was to investigate the relationship between the 24-h MB and FMS in preschoolers using a compositional data analysis . Two hundred and four preschoolers (4.5 ± 0.8 years old; 101 boys) provided objectively assessed physical activity (PA) and sedentary behaviour (SB) data (Actigraph wGT3X), and FMS (TGMD-2). Sleep duration (SD) was reported by parents. Association of daily composition of movement behaviours with FMS was explored using compositional analysis and isotemporal substitution (R Core Team, 3.6.1). When considered as a 24-h MB composition (PA, SB and SD), adjusted for age, BMI and sex, the composition predicted locomotor (r² = 0.31), object control (r² = 0.19), and total motor score (r² = 0.35), respectively (all P < 0.001). Reallocation of time from light to moderate-to-vigorous PA was associated with greatest positive changes in total motor score. Achieving adequate balance between movement behaviours over the 24-h period, and its relationship with locomotor and object control skills should be considered and further investigated in early childhood.  相似文献

福州十番"丝竹锣鼓"的结构形式   总被引：2，自引：0，他引：2  

马达 《福建师范大学学报(哲学社会科学版)》2002,(2):119-124

福州十番是流传于福建省福州附近地区的一种民间器乐合奏形式。福州十番一般分为两类,一类是只用打击乐器演奏的“清锣鼓”,另一类是用民间管弦乐器加上打击乐器演奏的“丝竹锣鼓”。本文主要对“丝竹锣鼓”的结构形式进行研究,通过对几首代表性十番曲的分析,我们可以发现,“丝竹锣鼓、的曲调主要来源于曲牌,小调,哗牌等。曲牌是流行于当地的民间乐曲;小调是当地的民间小调;哗牌是当地流行的一些唢呐曲。“丝竹锣鼓”的曲式结构多为一段体,二段体,三段体及多段体形式;调式从为“正宫调”即（do=G)及其同宫系统的各调;节拍板式多为一板一眼的二拍子;速度一般是先慢后逐渐加快;配器手法主要是齐奏;旋律进行以级进为主,乐段内常以“起,承,转,合”的发展原则安排乐句,并常用四小为一乐句的相同乐句的重复。  相似文献   

爱情的琥珀：情爱的生灵——《荆棘鸟》中梅吉与拉尔夫的性爱     

陈达 《涪陵师范学院学报》2008,24(1):95-99

人类的性爱问题是我们无法回避的问题。考琳.麦卡洛《荆棘鸟》就直接触及了人类生命中最隐秘的角落——两性交融的性爱。她通过对梅吉与拉尔夫之间性爱历程的描写,探索了人类男女间的性爱,赞叹梅吉与拉尔夫之间的性爱。梅吉和拉尔夫的性爱既有具体的激情,又有抽象的超脱,是激情与超脱的有机结合,是神圣与世俗完美的统一,是情与欲、灵与肉的完美融合和同步共振。  相似文献
