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   

A Systemic Approach to Teacher Development: lessons from a national Logo‐based computers in education program     

Clottlde Fonseca 《Technology, Pedagogy and Education》2013,22(2):205-218

ABSTRACT

Teacher training is a key component of any computers in education program. This article addresses how success in teacher training depends on long‐term planning and on a flexible systemic approach to training and support. It describes the system of teacher development established within the context of a widespread national program reaching one out of three elementary school children in Costa Rica and the lessons learned over a five year implementation process.  相似文献   

Shadow Education in Spain: Examining Social Inequalities Through the Analysis of PISA Results     

Ariadne Runte-Geidel  Pedro Femia Marzo 《欧洲教育》2013,45(2):117-136

This article examines the use of shadow education by students of compulsory secondary education in Spain over the period 2000?2010. The study identifies the proportion of the student population that uses this type of education and examines how the use of shadow education has evolved during this period. Data was drawn from the student questionnaire in the PISA report, which gathered information on extra lessons in the four studies conducted between 2000 and 2009. The study also contrasted the data on the use of extra classes with the socioeconomic profile of students and other indicators of social inequality.  相似文献   

From the Margins to the Center: Debunking Claims about Southeast Asian American Masculinity     

Peter T. Keo  Pedro A. Noguera 《Equity & Excellence in Education》2013,46(2):199-216

This study reviews empirical data from the U.S. Census, American Community Survey (ACS) and academic journals to explore K-12 and higher educational outcomes pertaining to Southeast Asian American (SEAA) males. We argue that the empirical dismissal of SEAA males in social science research reinforces a longstanding agenda of structural neglect and invisibility. By disaggregating some of the existing data for Cambodian, Hmong, Laotian, and Vietnamese subgroups from the broader “Asian” group, we hope to repudiate the model minority myth and stereotypes related to masculinity. Findings revealed that SEAA males had K-12 and higher educational outcomes that contradict the standard conception of academic and financial success. We situate the findings of the article in a discussion of intersectionality and the mainstream cultural forces that impact SEAA males.  相似文献

Human capital and innovation: the importance of the optimal organizational task structure     

Tiago Fonseca  Pedro de Faria  Francisco Lima 《Research Policy》2019,48(3):616-627

Management literature has identified high-skilled human capital as a crucial dimension of innovation processes at the firm level. In this study, we introduce an alternative view of human capital based on the tasks that firms’ workers perform. We propose a measure of cognitive analytical and interpersonal tasks: the degree of abstractism. We argue that the level of abstractism of a firm has an effect on a firm's propensity to innovate and on its product innovation performance. We hypothesize that while the degree of abstractism has a linear positive relationship with the propensity to innovate, the relationship between abstractism and product innovation performance follows an inverted u-shaped relationship. We find partial support to our hypotheses using data from more than six thousand Portuguese firms. We discuss how these results change our understanding of the relationship between human capital and innovation at the firm level.  相似文献   

Developing and testing a method to measure academic societal impact          下载免费PDF全文

Paul Phillips  Luiz Moutinho  Pedro Godinho 《Higher Education Quarterly》2018,72(2):121-140

This paper aims to extend understanding of the business and societal impact of academic research. From a business school perspective, it has taken stock of the role of academic research and relevance in business and society. The proposed conceptual framework highlights the forces influencing the pursuit of academic rigour and relevance in scholarly outputs. A theoretical model for measuring the societal impact of academic journal articles—the Academic Rigour and Relevance Index (AR2I)—was developed. This index comprises six key parameters, which are assessed by three stakeholder groups connected with academic research into business issues, these groups being: business practitioners, society and academics. The behaviour of the AR2I model was evaluated using the Monte Carlo simulation model. Taking into account the relationships between the standard deviations and the differences of classification between articles with different levels of rigour and relevance, it is demonstrated that the AR2I model is an effective tool.  相似文献   

Power training in elite young soccer players: Effects of using loads above or below the optimum power zone     

Irineu Loturco  Lucas A. Pereira  Valter P. Reis  Chris Bishop  Vinicius Zanetti  Pedro E. Alcaraz 《Journal of sports sciences》2020,38(11-12):1416-1422

ABSTRACT

This study aimed to examine the effects of two jump squat (JS) training programs involving different loading ranges in under-20 soccer players during a preseason period. Twenty-three elite young soccer players performed sprint speed (at 5-, 10-, and 20-m), change-of-direction (COD) speed, JS peak-power (PP), and countermovement jump (CMJ) tests pre and post four weeks of training. Athletes were pair-matched in two groups according to their optimum power loads (OPL) as follows: lower than OPL (LOPL; athletes who trained at a load 20% lower than the OPL) and higher than OPL (HOPL; athletes who trained at a load 20% higher than the OPL). Magnitude-based inferences were used to compare pre- and post-training measures. Meaningful increases in the PP JS were observed for both groups. Likely and possible improvements were observed in the 5- and 10-m sprint velocity in the LOPL group. Meanwhile, possible and likely improvements were observed in the CMJ, 5- and 10-m sprint velocity, and COD speed in the HOPL group. Overall, both training schemes induced positive changes in athletic performance. Soccer coaches and sport scientists can implement the JS OPL-based training schemes presented here, either separately or combined, to improve the physical performance of youth soccer players.  相似文献   

Reference power values for the jump squat exercise in elite athletes: A multicenter study

ABSTRACT

The present study aimed to provide reference values for lower-limb muscle power assessed during the incremental jump squat (JS) test in elite athletes (i.e., professional athletes competing at international level). We pooled data from all JS tests performed by elite athletes of different sports in two high-performance centres between 2015 and 2019, and computed reference values (i.e., terciles) for mean power (MP), mean propulsive power (MPP), and peak power (PP). Reference values were obtained from 684 elite athletes (458 male and 226 female) of 16 different sports (boxing, judo, karate, fencing, taekwondo, wrestling, basketball, soccer, futsal, handball, rugby union, badminton, tennis, long distance running, triathlon, and sprinting). Significant differences (p < 0.001) were found between male and female athletes for MP (7.47 ± 1.93 and 6.15 ± 1.68 W·Kg^?1, respectively), MPP (10.50 ± 2.75 and 8.63 ± 2.43 W·Kg^?1), and PP (23.64 ± 6.12 and 19.35 ± 5.49 W·Kg^?1). However, the velocity at which these power measures was attained seemed to be independent of sex (~0.95, 1.00 and 2.00 m·s^?1 for mean, mean propulsive, and peak velocity, respectively) and homogeneous across different sport disciplines (coefficient of variation <10%). These data can be used to classify athletes’ power capabilities, and the optimum velocity ranges provided here could be useful for training purposes.  相似文献   

Child labour and educational success in Portugal     

Pedro Goulart  Arjun S. Bedi   《Economics of Education Review》2008,27(5):575-587

The current debate on child labour focuses on developing countries. However, Portugal is an example of a relatively developed country where child labour is still a matter of concern as between 8% and 12% of Portuguese children may be classified as workers. This paper studies the patterns of child labour in Portugal and assesses the consequences of working on the educational success of Portuguese children. The analysis controls for typically unobserved attributes such as a child's interest in school and educational ambitions and uses geographical variation in policies designed to tackle child labour and in labour inspection regimes to instrument child labour. We find that economic work hinders educational success, while domestic work does not appear to be harmful. Furthermore, after controlling for a host of socio-economic variables, factors such as a child's interest in school and educational ambitions have a large effect on boosting educational success and reducing economic work.  相似文献
