La diferencia de sexo en la resolución de problemas aritméticos: un estudio transversal     

José Tomás Bethencourt  Esteban Torres 《Infancia y Aprendizaje》2013,36(38):9-20

Resumen

En este trabajo se estudia la diferencia entre los sexos en la resolución de problemas aritméticos verbales. Participaron 1.078 escolares de los grados 3.°, 4.°, 5.°, 6.° y 8.° de E.G.B. Se aplicó una prueba de 17 problemas aritméticos a los escolares de 3°, 4° y 5° en dos sesiones. También se aplicó una prueba de 4 problemas aritméticos a los escolares de 6.° y 8.° Los resultados indican que sólo en 8.° los varones son más hábiles que las mujeres resolviendo este tipo de problemas. Se hacen algunas consideraciones adicionales sobre los factores del contexto familiar y escolar que puedan incidir sobre los resultados.  相似文献

ABSTRACT

To assess the effects of plyometric jump training (PJT) in female soccer player’s vertical jump height, a review was conducted using the data sources PubMed, MEDLINE, Web Of Science and SCOPUS. Only peer-review articles were included. To qualify for inclusion in the meta-analysis, studies must have included (i) a PJT programme of at least 2 weeks, (ii) cohorts of healthy female soccer players with no restriction for age, (iii) a control group, (iv) a measure of countermovement jump (CMJ). The inverse variance random-effects model for meta-analyses was used. From 7,136 records initially identified through database searching, 8 were eligible for meta-analysis, comprising 9 training groups (n = 99) and 9 control groups (n = 94). The magnitude of the main effect was moderate (ES = 1.01 [95%CI = 0.36–1.66], Z = 3.04, p = 0.002). Sub-group analyses were performed (i.e., PJT frequency, duration and total number of sessions), revealing no significant subgroup differences (p = 0.34–0.96). Among the studies included in this review, none reported injury or other adverse effects. In conclusion, PJT is effective in female soccer players for the improvement of vertical jump height. In future, research must identify specific dose–response relationships following PJT, particularly in the long term.  相似文献   

Individual and field citation distributions in 29 broad scientific fields     

Javier Ruiz-Castillo  Rodrigo Costas 《Journal of Informetrics》2018,12(3):868-892

Using an initial dataset consisting of 18.5 million distinct authors and 15 million distinct articles published in the period 2000–2016, which are classified into 29 broad scientific fields, we search for regularities at the individual level for very productive authors with citation distributions of a certain size, and for the existence of a macro-micro relationship between the skewness of a scientific field citation distribution and the characteristics of the individual citation distributions of the authors belonging to the field. Our main results are the following three. Firstly, although the skewness of individual citation distributions varies greatly within each field, their average skewness is of a similar order of magnitude in all fields. Secondly, as in the previous literature, field citation distributions are highly skewed and the degree of skewness is very similar across fields. Thirdly, the skewness of field citation distributions is essentially explained in terms of the average skewness of individual authors, as well as individuals’ differences in mean citation rates and the number of publications per author. These results have important conceptual and practical consequences: to understand the skewness of field citation distributions at any aggregate level we must simply explain the skewness of the individual citation distributions of their very productive authors.  相似文献   

Drug Testing,Sex Verification,and the 1967 Pan-American Games     

Sarah Teetzel  Cesar R. Torres 《国际体育史杂志》2016,33(1-2):127-146

Abstract

Despite frequent claims that invasive methods of sex verification and early procedures for doping detection were used in 1966 and 1967 at different major international sport competitions, little is known about the origins and rationales for implementing such procedures. This paper focuses on the drug testing and sex verification protocols implemented at the 1967 Pan-American Games held in Winnipeg. Specifically, it explores the conditions that led to these protocols, as well as the details of and the arguments invoked for their implementation. To do so, archival material, media coverage featured in English, French, Portuguese, and Spanish newspapers and magazines across the Americas, and oral histories are analyzed and discussed. The paper demonstrates that neither the sex verification nor the drug testing protocol was mandatory for all athletes and only two very specific groups of athletes were targeted. It also demonstrates that in the case of the former, exceptions were made within the specific group targeted. The paper concludes that the rudimentary protocols applied at the 1967 Pan-American Games likely informed the IOC Medical Commission’s doping and sex-testing policies implemented at the 1968 Mexico City Olympics and Grenoble Winter Olympics.  相似文献

La palabra complementada (cued speech). De la percepción visual del habla a la comprensión y producción de la palabra     

Santiago Torres 《Cultura y Educación》2013,25(10):71-84

Los sistemas paraverbales o que acompañan al habla son necesarios a todo hablante «normal». Algunos pueblos, como los latinos (frente a los anglosajones, por ejemplo), hacemos uso generoso y eficiente de ellos. Un trabajo sistemático con ellos ha permitido poner en marcha un método eficaz para la educación del lenguaje oral en niños sordos. En este artículo se expone en detalle el sistema, sus implicaciones y eficacia y los pasos a dar para su aplicación.  相似文献

Making citizens of the world: the political socialization of youth in formal mass education systems     

Alexander W. Wiseman  M. Fernanda Astiz  Rodrigo Fabrega  David P. Baker 《Compare》2011,41(5):561-577

Unique cross-national data on adolescents’ civic skills, knowledge, and political attitudes are used to examine the democratic processes of modern mass schooling, effects of national political systems, and patterns of youth political socialization in 27 nations. Compared to the generally weak reported effects on mathematics and reading achievement, we find robust effects of schooling on youths’ civics knowledge, skills, and attitudes. Secondly, there is empirical support for the importance of a supra-national political culture, beyond that of unique national cultures, in the political socialization of youth. Lastly, there is evidence of an emerging common polity among youth across nations. The results extend notions of the institutional influence of mass public schooling on the political socialization of youth.  相似文献
