From here to there and back again: the story of a mother,her son,disability, and school choice

Nelly and her children live in Queensland, Australia. When it came time for her second youngest son to start school, Nelly was not prepared for the difficulty that she had enrolling him at the school of her choice. In spite of her son's disability, Nelly thought that it was natural that he would go to his local school with his sister. It is not surprising that she expected this, given the legal and policy endorsement of inclusive education that exists in the Queensland education system. What unfolded in Nelly's life as she pursued this enrolment is the subject of this article. This is the story of a mother who believed in and hoped for inclusive schooling for her son but who found herself caught in a series of events and experiences which ultimately led to the decision to transfer him into a special school. This is also the story of how, disillusioned and regretful, she went on to undo that decision. Told primarily in Nelly's own words, this narrative provides a deep insight into one mother's efforts to exercise her parental authority, the difficulties she encountered in trying to do so, and the consequences for her son.

What did schools experience from participating in a randomised controlled study (PLAY) that prioritised risk and challenge in active play for children while at school?

‘Risky’ play is an important component of play, which positively affects the cognitive, social and emotional development of children. However, a growing culture of ‘risk aversion’ may be limiting the degree of risk that children are allowed to encounter. We undertook qualitative interviews with eight schools to examine the acceptability of an intervention designed to increase risk and challenge in the school playground (e.g. more rough-and-tumble play and tree climbing). Schools were overwhelmingly positive about the approach and all enjoyed participating. Each school believed many benefits occurred from increasing risk and challenge within play, including better behaviour, improved cooperation between children and increases in physical activity. There were some challenges for schools, but these were generally research related, and all were viewed as acceptable. Indeed, schools found the process enlightening, and upon completion of the two-year intervention often viewed play in quite a different light.     

Reading ability and sensitivity to morphological relations

The morpho-phonological nature of English orthography is examined in this study of the relation between morphological sensitivity and decoding ability in the latter elementary grades. Children in grades three to six were required to distinguish derivationally-related word pairs (e.g., nature-natural) from foil pairs that are related in spelling but not in morphology (e.g., ear-earth). The materials included both transparently-related (i.e., the second word incorporated the pronunciation of the first, as in person-personal) and complexly-related word pairs (i.e., the second word involved some change in pronunciation, as in atom-atomic). Across two experiments, these items were presented in either oral or written form along with various tests of reading ability, intelligence and phonological awareness. The results indicate that children's recognition of derivational relationships improved with grade-level. As anticipated, there was also a significant association between sensitivity to derivational relatedness and decoding ability which remains significant even when the word pairs were orally presented and even when phonological awareness in taken into account. Both phonological awareness and sensitivity to morphological structure emerge as important factors in decoding skill in the later elementary grades.     

两种不同纳米金修饰方法制备的Au/CeO2复合物的抗氧化性能

以水热法制备的CeO₂纳米棒为载体,分别采用溶胶法和沉积法对其进行纳米金修饰,得到两种不同纳米金修饰方法制备的Au/CeO₂复合物。在MV-Fenton体系中用紫外分光光度法对两种Au/CeO₂复合物的抗氧化性能进行研究。结果表明：溶胶法制备的Au/CeO₂（S-Au/CeO₂）比沉积法制备的Au/CeO₂（D-Au/CeO₂）展现出更好的抗氧化性能。进一步研究表明：沉积法制备过程可能破坏了CeO₂的表面结构,导致其抗氧化性能降低;另外,溶胶法负载的AuNPs和CeO₂之间的电子传递也使其抗氧化性能增强。     

Age-ordered shirt numbering reduces the selection bias associated with the relative age effect

When placed into age groups for junior sporting competition, the relative differences in age between children leads to a bias in who is evaluated as being talented. While the impact of this relative age effect (RAE) is clear, until now there has been no evidence to show how to reduce it. The aim of this study was to determine whether the selection bias associated with the RAE could be reduced. Talent scouts from an elite football club watched junior games and ranked players on the basis of their potential. Scouts were allocated to one of three groups provided with contrasting information about the age of the players: (1) no age information, (2) players’ birthdates or (3) knowledge that the numbers on the playing shirts corresponded to the relative age of the players. Results revealed a significant selection bias for the scouts in the no-age information group, and that bias remained when scouts knew the players’ dates-of-birth. Strikingly though, the selection bias was eliminated when scouts watched the games knowing the shirt numbers corresponded to the relative ages of the players. The selection bias associated with the RAE can be reduced if information about age is presented appropriately.     

The effect of biofeedback training on affective regulation and simulated car-racing performance: a multiple case study analysis

The foundation of this study was based on an idiosyncratic concept, which uses probabilistic determinations (Kamata, Tenenbaum, & Hanin, 2002) to verify the utility and effectiveness of a biofeedback intervention by manipulating affective performance states in a race-car simulator. Nine males completed five separate time-trials of a simulated racing task and were then randomly assigned to one of three arousal regulation treatment conditions: (1) optimal, (2) poor, and (3) attention control. Following the biofeedback intervention, participants underwent another series of race trials to determine the effectiveness of the arousal regulation intervention. The results indicated that there were relative similarities in the strength and direction of the perceived and physiological states between the participants; however, the subtle details of the participants' unique performance zones and the probability of achieving each zone were revealed to be unique among the participants. The results also indicated that: (a) the biofeedback manipulation resulted in the expected changes for each participant, and (b) there were some large individual differences among the participants, necessitating the idiosyncratic approach. Limitations and future directions are also addressed.
