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

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.     

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

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.     

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

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.     

Match running performance and skill execution improves with age but not the number of disposals in young Australian footballers

This study investigated age-related differences in maturity, physical and functional characteristics and playing performance in youth Australian Football (AF). Young male players (n = 156) were recruited from 12 teams across 6 age groups (U10–U15) of a recreational AF club. All players were tested for body size, maturity and fitness. Player performance was assessed during a match in which disposals (kicks and handballs) and their effectiveness were coded from a video recording and match running performance measured using Global Positioning System. Significant main effects (P < 0.01) for age group were observed for age, years to peak height velocity, body mass, height, 20 m sprint, maximal speed over 20 m, vertical jump, 20 m multistage shuttle run, match distance, high-speed running distance, peak speed, number of effective disposals and percentage of effective disposals. Age-related differences in fitness characteristics (speed, lower body power and endurance) appeared to transfer to match running performance. The frequency in which players disposed of the football did not differ between age groups, however the effectiveness of each disposal (i.e., % effective disposals) improved with age. Match statistics, particularly those that evaluate skill execution outcome (i.e., effectiveness), are useful to assess performance and to track player development over time. Differences between age groups, and probably variability within age groups, are strongly associated with chronological age and maturity.     

Global Citizenship and Global Universities. The Age of Global Interdependence and Cosmopolitanism

This article focuses on the role of global universities and globalisations in an age of global interdependence and cosmopolitanism. Competing agendas that result from actions and reactions to multiple globalisations are considered in relation to global citizenship education. These agendas are crucial in understanding dilemmas of the local and the global in relation to education. Key emerging agendas are highlighted, including those of the hyperglobalisers, skeptics and transformationists. Three themes are central for this conversation, namely a) how multiple globalisations are impacting global life and academics, b) how networks have become privileged sites for global education, and c) the implications of globalisation and networks for global citizenship and global universities.     

Training Effects on Older Adults in Information and Communication Technologies Considering Psychosocial Variables

The main aim of this study is to contribute knowledge about the impact of the use of information and communication technologies (ICT) on the self-concept, mood, and quality of life of institutionalized older adults in retirement homes and day care centers (Portuguese institutions). It also studies the influence of independent variables such as age; education; referral to the institution (own initiative, indicated by friends, indicated by family, indicated by social security); attendance schedule; and visits from family and friends. The study comprised 41 participants organized into two groups: 22 older adults in the ICT Group and 19 older adults in the Passive Control Group. There were three evaluation periods: before the onset of intervention and 11 and 22 months after intervention began. The results demonstrate that involvement with information and communication technologies produced positive effects on older adults’ social behavior and their self-perception of physical and environment facets of quality of life. Moreover, they suggest that there is a relationship between psychosocial variables and independent variables.     

Where did I come from? US parents' and preschool children's participation in sexual socialisation

This paper applies a sociology of childhood approach to the study of the sexual socialisation of young children in the USA. It examines both children's and parents' active participation in this dynamic and collaborative process through conversations between 49 parents and their 54 preschool children that were audio-recorded while they read books about ‘where babies come from’. Parents also participated in a brief survey. The authors found that, while parents do foreclose such conversations as previous research has indicated, they also use a variety of other tactics, including adding information and emotion management. These findings illustrate children's active engagement in their own sexual socialisation through their questions, confusions and distractions, which affected the amount and type of information that was elicited.     

Using participatory action research to address absenteeism

Many urban high schools serving low-income families have below-average attendance rates, which can indicate that fewer students are prepared to matriculate into college and career opportunities. Through the use of participatory action research (PAR), we – a group of four educators at Wilson High School – have changed school policies and procedures in order to address our school's most problematic behavior: students cutting class. Through the processes and outcomes that our group, the Class Cutting Task Force, has experienced, we have called upon action learning (AL) in our focus on practical and experienced problems, and we have learned an important lesson: without clear and consistent school-wide expectations, our students cannot meet their potentials. Additionally, we have become empowered to drive a school-wide improvement initiative from the ground up by using the four-stage PAR process. It is our experience with the PAR process as a method of engagement in AL for school practitioners that we aim to share in this account of practice.
