Contextual effects on predicting risk for reading difficulties in first and second grade

This study utilized early reading assessment data from a randomized trial of 210 urban and rural schools in Texas to examine contextual effects on risk prediction in first and second grade. The primary objective was to examine the roles of (a) individual differences, (b) the grade 1 classroom, and (c) the pairing of first and second grade teachers in determining grade 2 outcomes in word reading and fluency. A second objective was to investigate whether the administration format of the assessment (paper, paper plus desktop, handheld plus desktop) or the level of teacher support (web mentoring, no mentoring) moderated the prediction. These moderator variables proved not to be significant. Subsequent analyses found that a combination of student pretest and mean of pretest classroom was a better predictor than student pretest alone. Additionally, the effect of student scores varied by teacher-pair. On average, intraclass correlations (ICCs) ranged from 6% to 17%. Differences in ICCs at the classroom level were much greater than at the school level, and differences in urban schools were twice that of rural schools.

Empowering and protecting children by enhancing knowledge,skills and well-being: A randomized trial of Learn to BE SAFE with Emmy™

Australia needs effective programs to protect children and prevent abuse, but there is little information available for policymakers or families. Using a randomized controlled trial, Learn to BE SAFE with Emmy™, a school-based protection program for young children designed by Act for Kids, was evaluated to determine its effectiveness for promoting young children's knowledge and skills. Grade one children (n = 245) from 15 classrooms across 5 primary schools completed assessment measures. A subset of these children received the program (n = 131) or acted as a comparison group (n = 114). Parents (n = 72) completed questionnaires about their child's participation in the program. When compared with children who had not received the program, children who completed Learn to BE SAFE with Emmy™ demonstrated increased knowledge of interpersonal safety and were more likely to choose a safe response option to hypothetical unsafe scenarios 6 months after participation than at both pre- and post-intervention. Parents reported their children who participated used more safety strategies immediately and 6 months after participation compared to pre-intervention. Outcomes can assist in guiding future policies around the prevention of child abuse and protect the well-being of Australian children.     

论刑罚的目的

本文探讨我国刑罚目的的选择。兼容报应观与预防观,不仅具有理论方面的可行性,也具有实践方面的必要性,具体如何兼容需符合我国的国情。将我国刑罚目的分为根本目的、直接目的和间接目的是合宜的,因为这三种目的蕴涵了报应观和预防观,并且使报应和预防得到完美的结合,它们构成了我国刑罚目的的有机统一体。

跳水常见损伤防治研究

跳水是我国的传统优势项目,同时也属于高危运动项目,从高空中跳下存在各种安全隐患,导致跳水运动员受伤概率较高。伤病是导致我国运动员提前退役的主要原因,也是我国跳水训练是否科学最具争议的因素之一。研究从训练学角度入手,采用文献研究法和调查法,收集统计跳水受伤的部位和特征,分析受伤的训练学原因,探讨防治跳水运动损伤的措施和手段,以期为我国跳水训练提供参考和帮助。
