Using Luhmann’s communication theory and affordance theories, we develop a framework to examine how kindergarten-grade 2 students interact with tablet computers. We assessed whether cognitive ability and device configuration influence how successfully children use tablet computers. We found that children’s limited ability to direct their cognitive resources affects child–tablet communication (i.e., sending and receiving information to and from the device). While it may appear that children simply know how to use this technology, they are actually engaged in a systematic assessment of the device governed by their level of attentional maturity. Interestingly, tablet computers designed for adults result in a higher frequency of successful communication but prolonged communication was most likely to take place on child-focused tablet computers. It seems that communication success and user engagement are independent. 相似文献

In the current essay, Kevin Burke and Adam Greteman challenge this thing called love by looking at how we might instead “like” in education. Within education, multiculturalism can be viewed as a way of loving, or learning to love, diversity and, as such, learning to love the self; this tendency is notably apparent in the recent rise of concern expressed about student self‐esteem. According to the authors, however, critical research on multiculturalism demonstrates how, in loving diversity, multicultural discourses limn the possibilities for subjects to come into being and be liked for their differences. Drawing on James Alison's On Being Liked, Burke and Greteman reframe the problem of relating in education instead through the language of liking. How does the shift from loving to liking — either our students, our teachers, or ourselves — create different social dynamics and ethical paradigms? In engaging this question, Burke and Greteman offer an alternative model of liking that is based on the practice of cruising. 相似文献

This exploratory study examined the relation between pubertal timing and dimensions of ethnic-racial identity among adopted Korean Americans raised transracially in White families. The study also examined whether internalized racism moderated the association between pubertal timing and ethnic-racial identity. Adopted Korean American adolescents (N = 202; 108 females; ages 13–19 years) completed measures of pubertal development, ethnic-racial identity, and internalized racism in 2007. There was no significant main effect of pubertal timing for either male or female adolescents. Internalized racism moderated the relation between pubertal timing and ethnic-racial identity clarity (B = −.16, p = .015) among male adolescents. Specifically, earlier pubertal timing was significantly associated with lower ethnic-racial identity clarity for male adolescents with higher levels of internalized racism. 相似文献

In this article, we outline the initial stages in development of an assessment instrument for Australian Sign Language and explore issues involved in the development of such a test. We first briefly describe the instruments currently available for assessing grammatical skills in Australian Sign Language and discuss the need for a more objective measure. We then describe our adaptation of an existing American Sign Language test, the Test Battery for American Sign Language Morphology and Syntax. Finally, this article presents some of the data collected from a group of deaf native signers. These data are used to demonstrate the range of variability in key grammatical features of Australian Sign Language and to raise methodological issues associated with signed language test design. 相似文献

This study investigated the influence of external load training (ELT) on static and dynamic balance. Nineteen females stratified into two groups (ELT = 9, control = 10) completed three testing sessions over 6 weeks. The ELT group wore weighted vests (WV) of ~8% body mass for 32 h/week during daily living and three training sessions/week for 3 weeks. Following completion of ELT, a 3 week detraining (DET) phase was completed. Bilateral and unilateral static balance were assessed with eyes open and closed. Dynamic balance was assessed using the star excursion balance test (SEBT). Static and dynamic balance variables were analysed using a 2 (group) x 3 (time) between participants repeated measures ANOVA (p < 0.05). Results revealed significant reductions in average centre of pressure (COP) velocity in the control group on the non-dominant limb with eyes closed, and significantly greater reach distances in the ELT group on the SEBT for the posteromedial and medial directions on the dominant limb (p < 0.05). These findings suggest the ELT group did not significantly improve their balance in comparison to the control group. However, future research should further examine this unique, supplemental training method and the impact on balance performance. 相似文献

Although the biomechanical properties of the various types of running foot strike (rearfoot, midfoot, and forefoot) have been studied extensively in the laboratory, only a few studies have attempted to quantify the frequency of running foot strike variants among runners in competitive road races. We classified the left and right foot strike patterns of 936 distance runners, most of whom would be considered of recreational or sub-elite ability, at the 10 km point of a half-marathon/marathon road race. We classified 88.9% of runners at the 10 km point as rearfoot strikers, 3.4% as midfoot strikers, 1.8% as forefoot strikers, and 5.9% of runners exhibited discrete foot strike asymmetry. Rearfoot striking was more common among our sample of mostly recreational distance runners than has been previously reported for samples of faster runners. We also compared foot strike patterns of 286 individual marathon runners between the 10 km and 32 km race locations and observed increased frequency of rearfoot striking at 32 km. A large percentage of runners switched from midfoot and forefoot foot strikes at 10 km to rearfoot strikes at 32 km. The frequency of discrete foot strike asymmetry declined from the 10 km to the 32 km location. Among marathon runners, we found no significant relationship between foot strike patterns and race times. 相似文献

ABSTRACTHot water immersion, known as a hot bath, is used by MMA athletes to produce rapid weight loss (RWL) by means of passive fluid loss. This study investigated the magnitude of body mass losses using a standardized hot bath protocol with or without the addition of salt. In a crossover design, eleven male MMA athletes (28.5 ± 4.6 y; 1.83 ± 0.07 m; 82.5 ± 9.1 kg) performed a 20-min immersion at 37.8°C followed by a 40-min wrap in a warm room. This bath and wrap was performed twice per visit. During one visit, only fresh water was used (FWB), and in the other visit, magnesium sulphate (1.6% wt/vol) was added to the bath (SWB). Prior to each visit, 24 h of carbohydrate, fibre, and fluid restriction was undertaken as part of the RWL protocol. Body mass losses induced by the hot bath protocols were 1.63 ± 0.75 kg and 1.60 ± 0.80 kg for FWB and SWB, respectively, and equivalent to ~2.1% body mass. Under the conditions employed, the magnitude of body mass loss in SWB was similar to FWB. However, further research should explore bathing in a temperature that is consistent with that habitually used by fighters, and/or higher concentrations of salt. 相似文献
