女性小说文本叙事话语的对话性

当今学领域，女性失语症并未终结。为了消除女性失语症，把叙事学和性别因素结合起来从对话性的角度锲入女性学，探讨了女性小说本叙事话语的前提、理论基础和具体表现，提倡女性小说本叙事话语的对话性这种写作策略。女性小说本叙事话语的对话性的具体体现又主要以结构上的暗辩体、不可靠叙述、人物的“抢话”、转述语中的自由间接引语为典型。女性小说本叙事话语的对话性是女性学与叙事话语的契合。它为建构女性话语提供了一种切实可行的途径、方法，为女性写作开拓了一个新的空间。它是一种策略化本质描述、一种具体的方法，而不是绝对化、普遍化的本质规定。它的直接目的是消除女性失语症，建构女性话语；最终目的是观照现实，改造现存的社会。我们高举的价值立场是不具有强权性的女性人主义价值立场。它瓦解、颠覆的是男权制度、男权话语而不是具体的丰富的个体男人。     

Tracking club sport participation from childhood to early adulthood

This study examined the strength of tracking sport participation from childhood to early adulthood among the Dunedin Multidisciplinary Health and Development Study cohort. Participation in sport, dance, or gymnastics as part of a club or group (outside of school) was assessed at ages 7, 9, 15, 18, and 21 years. In addition to the traditionally used correlation coefficients, summary statistics (intraclass correlations; ICC) from random effect models and stability coefficients from generalized estimating equations (GEE) were calculated using all the longitudinal data and controlling for the influence of covariates on tracking strength. Correlation coefficients revealed statistically significant tracking of club sport participation (7-21 years) at low levels (r = .07-0.28). The ICC summary statistic (0.23) was consistent with this, while the GEE suggested moderate tracking (0.59). The results of this study suggest that encouraging sport participation during childhood and adolescence may result in a modest increase in the likelihood of participation later in life. However, the substantial movement into and out of sport participation observed here and in other studies cautions against relying solely on sport promotion among youth as a strategy to promote lifelong participation.     

耐力训练对大鼠跟腱超微结构及IGF—I表达的动态观察

目的:探讨耐力训练对大鼠跟腱超微结构的影响,同时观察内源性IGF-I表达的动态变化情况。方法:SD大鼠20只,随机分为2组,每组各10只,运动组进行12周的跑台运动,运动结束后分别观察跟腱的超微结构以及IGF-I表达的变化情况。结果:超微结构观察显示长期跑台运动组大鼠跟腱的腱细胞含量增加,同时,大鼠跟腱中IGF-I mRNA和蛋白含量显著性增加。结论:IGF-I在运动所致跟腱的适应性改建过程中可能具有重要作用。     

Tinkering through transition: on ‘doctoring’ as an early-career academic in physical education and sport pedagogy

This article addresses the notion of ‘making it’ as an early-career academic in physical education and sport pedagogy. In it, we draw on the tradition of material semiotics to reflect on our shared journeys from doctoral student to beginning scholar and beyond. By attuning ourselves to the relationality, materiality and precariousness of our experiences, we offer an answer to the question of what it takes to ‘make it’ as an early-career academic by advocating the practice of ‘making do’ or ‘doctoring.’ We develop this argument, first, by describing the narrative methods we used to conduct our inquiry and by explaining the material-semiotic ideas we used to explore the stories it generated. Then, we tell tales of our transitions from higher degree research student to early-career academic, focusing specifically on our ongoing, collective efforts to make do. In our discussion, we explore these narratives and attend to three features of our actions and activities as early-career academics; namely semiotic relationality, material heterogeneity and the precarious processes of heterogeneous engineering through which we sought to make a career in our field. We conclude by encouraging beginning scholars in physical education and sport pedagogy to become sensitive to these aspects of their own agency, and to experiment, experience and tinker together in ways that are attentive, inventive, caring and persistent.     

Do the physical and environment PETTLEP elements predict sport imagery ability?

The present study aimed to examine whether physical and environment elements of PETTLEP imagery relate to the ability to image five types of sport imagery (i.e. skill, strategy, goal, affect and mastery). Two hundred and ninety participants (152 males, 148 females; M_age?=?20.24 years, SD?=?4.36) from various sports completed the Sport Imagery Ability Questionnaire (SIAQ), and a set of items designed specifically for the study to assess how frequently participants incorporate physical (e.g. ‘I make small movements or gestures during the imagery’) and environment (e.g. ‘I image in the real training/competition environment’) elements of PETTLEP imagery. Structural equation modelling tested a hypothesised model in which imagery priming (i.e. the best fitting physical and environment elements) significantly and positively predicted imagery ability of the different imagery types (skill, β?=?0.38; strategy, β?=?0.23; goal, β?=?0.21; affect, β?=?0.25; mastery, β?=?0.22). The model was a good fit to the data: χ² (174)?=?263.87, p?<?.001, CFI?=?.96, TLI?=?.95, SRMR?=?.09, RMSEA?=?0.05 (90% CI?=?0.03–0.05). Findings displayed that priming imagery with physical and environment elements is associated with better skill, strategy, goal, affect and mastery imagery ability. The findings extend models of imagery use by indicating that how athletes images may influence their imagery ability.     

Building Trust Through Culturally Reciprocal Home-School-Community Collaboration from the Perspective of African-American Parents

This article presents findings of an instrumental case study that examined the perceptions held by African-American parents on the efficacy of schools in meeting the needs of African-American learners in a North Carolina community. A theme of distrust emerged and evidenced the need for teachers, administrators, and teacher educators to reconsider approaches used with African-American parents, particularly where building culturally reciprocal home-school-community relationships is concerned.

论OECD成人技能评估的演变 ——从IALS到ALL再到PIAAC

OECD从20世纪90年代起就开始对成人技能的水平进行评估,先后推出了IALS、ALL与PIAAC三大成人技能评估.历经20多年的发展,OECD进行成人技能评估的目标、内容和指标框架也不断扩展、深入和细化.通过对OECD的一系列成人技能评估进行梳理和分析,以期理解成人技能的内涵.
