Gendered Readings: Helping boys develop as critical readers

ABSTRACT This paper reports recent findings from a national survey of the reading habits of boys and girls aged 10, 12 and 14. Boys' reading habits are considered in the light of concerns about boys' underachievement in school, and in relation to girls' reading and changing patterns of literacy over time. The authors argue that helping boys develop as critical readers involves taking their voluntary reading seriously and rejecting deficit models. The paper argues that boys need to be encouraged to understand how they have been socially constructed as readers; they need to be engaged in discussion about their reading and the implications of the choices they make. It is only by taking differences seriously that critical and discerning readers will bedeveloped, and critical readers are necessary to undermine current highly gendered reading practices which potentially disadvantage both sexes.     

Divergent Ontologies with Converging Conclusions: A case study comparison of comparative methodologies

Informed by different ontologies, rival research traditions in comparative education forward divergent epistemological platforms, types of analyses and conclusions for the comparative education community. This article examines two studies of educational designs in socialist states-- Joseph Farrell's study of Allende's Chile and Jonathon Jansen's study of Mugabe's Zimbabwe--both of which share remarkably similar conclusions, despite their disparate geo-cultural contexts, as well as divergent research methodologies. Through a comparative analysis of the religio-political conflicts highlighted in each study's conclusion, as well as the research methodologies utilised by each comparativist, this article suggests that rival research traditions can not only arrive at similar conclusions, but offer one another complementary, though divergent, ontologies, which together offer a more complete and fuller picture of the reality or realities being studied.     

Execution time, kinetics, and kinematics of the mae-geri kick: comparison of national and international standard karate athletes

Little is known of the performance characteristics of the shotokan karate mae-geri kick. The aim of this study was to compare the execution time, the lower limb kinetics and kinematics, and their respective repeatability in the mae-geri kick of karate athletes of two different standards. Seventeen adult black belt karate competitors (9 national and 8 international athletes) performed six kicks with their dominant lower limb on a striking surface, combining maximum force impact and velocity. Execution time of movement and lower limb kinematics were recorded with a high-speed camera. Maximum force at impact and the forces exerted on the ground were measured using three force plates. The duration of the kick was significantly shorter for international than for national standard athletes. However, no significant difference in the maximum impact force of the kick was observed between the two groups. In addition, significant kinematic differences were observed between the groups, with two angles of motion and one velocity peak occurring sooner in the kick movement for the international athletes, specifically for the knee joint. International athletes also performed the kick with a significantly higher repeatability for duration and kinematics, specifically during the pre-loading phase that precedes the attack phase. We conclude that the duration of the kick and repeatability of lower limb kinematics could be useful in selecting top-level karate athletes and monitoring their training status.

Unstable footwear as a speed-dependent noise-based training gear to exercise inverted pendulum motion during walking

ABSTRACT

Previous research on unstable footwear has suggested that it may induce mechanical noise during walking. The purpose of this study was to explore whether unstable footwear could be considered as a noise-based training gear to exercise body center of mass (CoM) motion during walking. Ground reaction forces were collected among 24 healthy young women walking at speeds between 3 and 6 km h^?1 with control running shoes and unstable rocker-bottom shoes. The external mechanical work, the recovery of mechanical energy of the CoM during and within the step cycles, and the phase shift between potential and kinetic energy curves of the CoM were computed. Our findings support the idea that unstable rocker-bottom footwear could serve as a speed-dependent noise-based training gear to exercise CoM motion during walking. At slow speed, it acts as a stochastic resonance or facilitator that reduces external mechanical work; whereas at brisk speed it acts as a constraint that increases external mechanical work and could mimic a downhill slope.     

From Marin County's Seventies Clunker to the Durango World Championship 1990: A History of Mountain Biking in the USA

Between the 1970s, during which several enthusiastic cyclists rode off-road, and the 1990s, during which the first Union Cycliste Internationale World Championship took place in Durango (Colorado), different steps contributed to the success of mountain bike in the US. Inventions took place throughout the period from Gary Fisher's mechanical improvements in 1975 to Joe Breeze's first specialized frames made in 1977. In the same fashion, the ‘Stumpjumper’ was sold on a large scale in 1982, making it the first industrially-produced mountain bike, which led to a new stage in terms of commercialization. The mountain bike opened a new market in the cycling industry and certainly became more financially accessible to a large number of people. This sport, which began in the US, became a worldwide outdoor sport in the last decade of the twentieth century when the Olympics welcomed it with open arms at the Atlanta Olympic Games.
