Modeling the influences of upper-elementary school students’ digital reading literacy,socioeconomic factors,and self-regulated learning strategies

Background: Reading is an interactive and constructive process of making meaning by engaging a variety of materials and sources and by participating in reading communities at school or in daily life.

Aim: The purpose of this study was to explore the factors affecting digital reading literacy among upper-elementary school students.

Method: A 3-stage stratified cluster sampling was implemented that resulted in a sample of 592 upper-elementary students from 29 classes in 7 schools. Self-Regulated Learning Strategies Assessment (S-RLSA), Digital Reading Literacy Assessment (DRLA), and student reports of their parents’ education backgrounds were used to collect data on the outcome and predictor variables. Interpretation of these data involved two highly regarded statistical techniques. First, structural equation modeling was used to explore relationships amongst the constructs. Second, multi-group invariance (MI) analyses were used to assess the influence of parental education and self-regulated learning strategies on students’ digital reading literacy.

Results: Enriching students’ family learning resources and strengthening their self-regulated learning abilities could have very important influences on promoting upper-elementary school students' digital reading literacy -webpage information retrieval, reading and communication abilities.

Conclusions: This study also provides information on how teachers can address student resources to improve digital reading literacy and self-regulated strategies.

图书馆数字资源整合与管理

过去我们使用的各种数字资源都以一种零散的、孤立的状态存在着，相互之间缺乏联系，检索界面繁多且不统一，给读者利用数字资源带来很大不便。因此，本文笔者认为主要是对大量的数字资源进行整合，并提出了理想的整合目标和研究方向，最后介绍了国内外数字资源整合最新研究成果。     

Co-evolution of physical and social technologies in clinical practice: The case of HIV treatments

In this paper, we investigate the interplay of clinical knowledge and technological capabilities in the recent development of HIV/AIDS treatments and offer qualitative and quantitative evidence from the empirical setting of Italian practice. The study contributes to the literature on the co-evolution of physical and social technologies in medical innovation by showing how professional guidelines, systematic evaluative research and local coordination mechanisms contribute actively to the resolution of the uncertainty that surrounds technological advances, while leaving room for largely discretional therapeutic choices. The resulting variety in implementation strategies improves health outcomes, but may reduce productive efficiency.

基于GML和空间数据仓库技术的GIG数据共享模式研究

传统的GIS系统缺乏统一的数据格式标准,不同应用系统之间由于文件存储格式不同而无法实现直接数据共享。空间数据仓库技术可以实现GIS数据存储的统一标准化和应用的深层化,而GML的空间数据转换技术可实现Web环境下GIS数据的高速传输和共享。在对现有GIS数据共享方案及其中的各种数据共享模式进行分析的基础上,指出其中的不足之处,然后提出了面向管理的GIS数据共享模式,并就其实施模式和特点进行了研究。
