Indigenous knowledge and science revisited   总被引：3，自引：3，他引：0  

Glen S. Aikenhead  Masakata Ogawa 《Cultural Studies of Science Education》2007,2(3):539-620

This article provides a guided tour through three diverse cultural ways of understanding nature: an Indigenous way (with a focus on Indigenous nations in North America), a neo-indigenous way (a concept proposed to recognize many Asian nations’ unique ways of knowing nature; in this case, Japan), and a Euro-American scientific way. An exploration of these three ways of knowing unfolds in a developmental way such that some key terms change to become more authentic terms that better represent each culture’s collective, yet heterogeneous, worldview, metaphysics, epistemology, and values. For example, the three ways of understanding nature are eventually described as Indigenous ways of living in nature, a Japanese way of knowing seigyo-shizen, and Eurocentric sciences (plural). Characteristics of a postcolonial or anti-hegemonic discourse are suggested for science education, but some inherent difficulties with this discourse are also noted.

Racial self-categorization in adolescence: multiracial development and social pathways     

Hitlin S  Scott Brown J  Elder GH 《Child development》2006,77(5):1298-1308

Research on multiracial individuals is often cross-sectional, obscuring the fluid nature of multiracial self-categorization across time. Pathways of racial self-identification are developed from a nationally representative sample of adolescents aged 14-18, measured again 5 years later. A significant proportion of multiracial adolescents change racial self-identification across time. Youth who ever report being multiracial are 4 times as likely to switch self-identification as to report consistent multiracial identities. Across this time, more multiracial adolescents either add a racial category (diversify) or subtract one (consolidate) than maintain consistent multiracial self-categorization. Exploratory multinomial analyses show few differences between these pathways on select psychological and social characteristics. Results lend quantitative support to qualitative studies indicating the fluidity of racial self-categorization.  相似文献

Physiological responses and time-motion characteristics of various small-sided soccer games in youth players     

Hill-Haas SV  Dawson BT  Coutts AJ  Rowsell GJ 《Journal of sports sciences》2009,27(1):1-8

The aim of this study was to examine acute physiological responses and time-motion characteristics associated with three different small-sided soccer game formats in youth players. Sixteen male soccer players aged 16.3+/-0.6 years (mean+/-s) completed three variations of a small-sided game (i.e. 2 vs. 2, 4 vs. 4, and 6 vs. 6 players) in which heart rate, rating of perceived exertion (RPE), blood lactate concentration, and time-motion characteristics were recorded. The pitch size was altered to keep the relative pitch area per player consistent for each game format. The 2 vs. 2 games exhibited greater blood lactate, heart rate, and RPE responses compared with 4 vs. 4 and 6 vs. 6 games (P<0.05). The players travelled less (P<0.05) distance at speeds of 0-7 km.h(-1) in the 4 vs. 4 compared with the 2 vs. 2 games (1128+/-10 m and 1176+/-8 m, respectively). Average maximal sprint distances above 18 km.h(-1) were lower (P<0.05) in 2 vs. 2 than in 4 vs. 4 and 6 vs. 6 games (11.5+/-3.9 m, 15.3+/-5.5 m, and 19.4+/-5.9 m, respectively), and in 4 vs. 4 compared with 6 vs. 6 games. The results show that as small-sided game formats decrease in size and relative pitch area remains constant, overall physiological and perceptual workload increases.  相似文献   

Maximal work production following two levels of artificially induced metabolic alkalosis   总被引：2，自引：1，他引：1  

D C McKenzie  K D Coutts  D R Stirling  H H Hoeben  G Kuzara 《Journal of sports sciences》1986,4(1):35-38

In order to determine the influence of two artificially induced alkalotic states on the ability to perform maximal exercise, six male subjects (mean age, 22.0 years; mean height, 176.8 cm; mean weight, 69.1 kg; mean VO2 max, 3.83 l min-1) were studied during three experimental trials. The subjects performed six 60-s cycling bouts, at a work rate corresponding to 125% VO2 max, with 60 s recovery between work bouts; these regimens were performed 1 h after the ingestion of a solution containing either; I, placebo; II, NaHCO3 in a dosage of 0.15 g per kg body weight; or III, NaHCO3 0.30 g per kg body weight. The sixth work bout was continued until the pedal velocity dropped below 50 rev min-1. Total work done for the entire work period was calculated. Blood samples were taken from a forearm vein prior to the exercise bouts for analysis of pH and HCO3. The results showed a significant pre-exercise difference in pH and HCO3 for all conditions (P less than 0.01). In conditions where artificial alkalosis had been achieved prior to exercise there was significant increase in the work produced: I, 121.6 kJ; II, 133.1 kJ; III, 133.5 kJ (P less than 0.05). The time to fatigue in the six bout was also significantly increased; I, 74.7 s; II, 111.0 s; III, 106.0 p (P less than 0.05). There were no significant differences between conditions II and III. Thus augmentation of the bicarbonate reserves has a significant positive effect on the energy metabolism in interval-type exercise, leading to an increase in the work done and in the time to fatigue.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献   

Evaluation of the "under-21 rule": do young adult soccer players benefit?     

Vaeyens R  Coutts A  Philippaerts RM 《Journal of sports sciences》2005,23(10):1003-1012

Young adult soccer players often encounter difficulty progressing from youth competition to being regularly selected for high-level, open-age competition. In an attempt to increase the playing opportunities of semi-professional and amateur under-21 players in first teams, the Royal Belgian Football Association required national division teams to include at least two players younger than 21 in their match selection (under-21 rule). Over four seasons, the following variables were analysed across 2138 semi-professional and amateur soccer players aged 16-39 years: (1) the number of times a player was selected to be in the first team squad; (2) the number of times a player was selected to play in the starting line-up; and (3) the number of minutes played. Chi-square analysis demonstrated that second and third division teams had complied with the new selection regulations. However, two-way analysis of variance of individual player data revealed no increase in the number of playing minutes in the under-21 group. It would appear that many teams had complied with the new regulations by selecting young players as substitutes. The results highlight the difficulties that talented young soccer players experience progressing from youth to senior competition. We conclude that the rule imposed by the Royal Belgian Football Association has failed to improve the playing opportunities of young adult soccer players. Alternative strategies for increasing playing opportunities for young talented players are required.  相似文献
