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   

The Relations of Maternal Practices and Characteristics to Children''s Vicarious Emotional Responsiveness   总被引：1，自引：0，他引：1  

Nancy Eisenberg  Richard A. Fabes  Gustavo Carlo  Debra Troyer  Anna Lee Speer  Mariss Karbon  Galen Switzer 《Child development》1992,63(3):583-602

This study examined the relations of maternal vicarious emotional responding and child-rearing practices, as well as familial emotional environment, to 5-6 and 8-9-year-old children's vicarious emotional responding. There were some correspondences between mothers' and children's heart rate, facial, and self-reported reactions to a sympathy-inducing film. Maternal sympathy/perspective taking and reinforcement of sympathy/prosocial behavior, as well as negative subordinate emotion in the home, were associated with markers of girls' sympathy; mothers' personal distress (for girls), restrictiveness regarding displays of hurtful negative emotions (particularly for young girls), and negative dominant emotion in the home (for both sexes) were associated with markers of personal distress. Mothers' linking of the film character's experience to children's own experience was associated with children's responsiveness to the film, and mother's verbalizations during the film concerning her own emotional state and role taking were associated with boys' self-reported sympathy.  相似文献   

Yo-Yo Intermittent Endurance Test-Level 1 to monitor changes in aerobic fitness in pre-pubertal boys     

Luís Fernandes  Peter Krustrup  Gustavo Silva  Antonio Rebelo  José Oliveira 《European Journal of Sport Science》2016,16(2):159-164

The present study aimed to examine the performance and heart rate responses during the Yo-Yo Intermittent Endurance Test-Level 1 (Yo-Yo IE1) in children under the age of 10. One hundred and seven male children (7–9 years) performed the Yo-Yo IE1 at the beginning (M₁), middle (M₂) and end (M₃) of the school year. Data from individual heart rate curves of the Yo-Yo IE1 were analysed in order to detect the inflection point between an initial phase of fast rise in heart rate values and a second phase in which the rise of the heart rate values is much smaller. The distance covered in the Yo-Yo IE1 improved from M₁ to M₃ (884 ± 496 vs. 1032 ± 596 m; p < 0.05; d = 0.27), with intermediate values for M₂ (962 ± 528 m). Peak heart rate (HR_peak) decreased from M₁ to M₂ and M₃ (204 ± 9, 202 ± 9 and 200 ± 9 bpm, respectively; p < 0.05; d = 0.25–0.42). The 7th shuttle of the test (280 m), corresponding to 2.5 min, was identified as the inflection point between the two phases. Also, absolute heart rate at the 7th shuttle decreased progressively throughout the year (185 ± 9, 183 ± 10, and 179 ± 10 bpm; p < 0.05; d = 0.31–0.61). The present study provides evidence of the usefulness of a maximal as well as a submaximal version of Yo-Yo IE1 as a tool to monitor changes in aerobic fitness in pre-pubertal children.  相似文献   

Examining the influence of international large-scale assessments on national education policies     

Gustavo E. Fischman  Amelia Marcetti Topper  Iveta Silova  Janna Goebel  Jessica L. Holloway 《教育政策杂志》2019,34(4):470-499

This paper examines whether, to what extent, and how international large-scale assessments (ILSAs) have influenced education policy-making at the national level. Based on an exploratory review of the research and policy literature on ILSAs and two surveys administered to educational policy experts, researchers, policymakers, and educators, our research found that ILSAs, with their multiple and ambiguous uses, increasingly function as solutions in search for the right problem – that is, they appear to be used as tools to legitimize educational reforms. The survey results pointed to a growing perception among stakeholders that ILSAs are having an effect on national educational policies, with 38% of respondents stating that ILSAs were generally misused in national policy contexts. However, while the ILSA literature indicates that these assessments are having some influence, there is little evidence that any positive or negative causal relationship exists between ILSA participation and the implementation of education reforms. Perhaps the most significant change associated with the use of ILSAs in the literature reviewed is the way in which new conditions for educational comparison have been made possible at the national, regional, and global levels.  相似文献   

Relations Among Parenting,Culture, and Prosocial Behaviors in U.S. Mexican Youth: An Integrative Socialization Approach     

Cara Streit  Gustavo Carlo  George P. Knight  Rebecca M.B. White  Sahitya Maiya 《Child development》2021,92(4):e383-e397

We examined the longitudinal relations among parental socialization practices—including acceptance or harsh parenting and ethnic socialization—ethnic identity, familism, and prosocial behaviors in a sample of U.S. Mexican youth. Participants included 462 U.S. Mexican adolescents (M_age at Wave 1 = 10.4 years old; 48.1% female), their mothers, and fathers at the 5th, 7th, 10th, and 12th grades. Results showed that maternal and paternal ethnic socialization predicted several forms of prosocial behaviors via ethnic identity and familism. Fathers’, but not mothers’, harsh parenting and acceptance had direct links to specific forms of prosocial behaviors. This study suggests the need for culturally informed theories that examine the reciprocal relations between two distinct domains of cultural socialization.  相似文献   

Parental preferences in the choice for a specialty school     

Lydia M. Prieto  Jonathan Aguero-Valverde  Gustavo Zarrate-Cardenas  Martin Van Maarseveen 《Journal of School Choice》2019,13(2):198-227

Choosing a specialty school involves huge challenges for families. This research aims to understand the behavioral process that leads families to choose among various specialty school programs. Discrete choice models, based on revealed preferences data from middle school applications in a large school district in Florida, are estimated using both, the top and all-ranked alternatives. This study returns insights into geographic settings, theme specialties and socioeconomic characteristics of applicants, schools and their relationships. Distance from home, the school’s academic quality, the school’s theme specialty, and the high percentage of applicant’s own race are found to be the strongest factors related to the decision to apply.  相似文献   

Longitudinal Relations Among Parenting Styles,Prosocial Behaviors,and Academic Outcomes in U.S. Mexican Adolescents          下载免费PDF全文

This article examined parenting styles and prosocial behaviors as longitudinal predictors of academic outcomes in U.S. Mexican youth. Adolescents (N = 462; Wave 1 M_age = 10.4 years; 48.1% girls), parents, and teachers completed parenting, prosocial behavior, and academic outcome measures at 5th, 10th, and 12th grades. Authoritative parents were more likely to have youth who exhibited high levels of prosocial behaviors than those who were moderately demanding and less involved. Fathers and mothers who were less involved and mothers who were moderately demanding were less likely than authoritative parents to have youth who exhibited high levels of prosocial behaviors. Prosocial behaviors were positively associated with academic outcomes. Discussion focuses on parenting, prosocial behaviors, and academic attitudes in understanding youth academic performance.  相似文献

An overview of educational policies in the countries of Latin America during the 1990s     

Gustavo Fischman  Silvina Gvirtz 《教育政策杂志》2013,28(6):499-506

In this paper we want to examine the construct of the Learning Society in its economic and social context in the UK. We will argue that the policy rhetoric which makes up the current discourse of the ‘learning’ society is both powerfully normative and unhelpfully reductionist and that it displaces and masks issues of inequality. The discourse of the Learning Society has conflated the achievement of increased levels of participation for 16‐ to 19‐year‐olds with the insertion of market mechanisms and relations and the assertion of self‐interest. This has meant that issues of exclusion, polarization and social justice have been systematically neglected. The Learning Society provides, we suggest, for a redrawing and relegitimation of patterns of exclusion. In particular, in a time of social crisis, middle‐class retrenchment (masked as familial duty) has re‐asserted itself, in part, through a specific, particular engagement with the Learning Society in order to ensure advantage and distinction. As Connell (1996: 5) puts it, this ‘is the point on which the politics of education markets mainly turns’. Thus, we believe it is critical to address the question, ‘Whose Learning Society'? We shall attempt this through a preliminary examination of data collected from a cohort of 16‐year‐olds who are in the process of transition from statutory schooling into a post‐16 education and training market (ETM), and deploy their ‘emergent narratives’ to problematize the normative simplicities of the Learning Society.  相似文献
