核心价值观与图书馆学基础理论

图书馆学基础理论以什么为原点,这是一个人们关注的理论问题。有人提出图书馆学应该象宇宙大爆炸一样有一个原点,从这一点发散开来。理论应该有原点,有逻辑,有体系。图书馆学研究模式从学科的研究对象开始,然后是研究的意义、目的、研究的任务、研究的方法、研究的手段、研究的     

A cross-national analysis of the student- and school-level factors affecting the demand for private tutoring

Private tutoring has become a worldwide phenomenon, yet there is little empirical evidence for the main factors leading the demand for private tutoring across nations. Using data from the Third International Mathematics and Science Study of 2003, this study classified the countries into four different groups according to the proportion of student participation in private tutoring and student achievement. Then, the study explored student- and school-level factors influencing the demand for private tutoring. From the HGLM analysis, the results revealed that the demand for private tutoring in Korea and Taiwan, which have higher participation rates in private tutoring and high-school-quality levels, is mostly explained by student-level variables (educational aspirations, instrumental motivation, self-confidence, and father’s education) and school context variables (the community size and school SES). Meanwhile, the demand for private tutoring in the Philippines and Romania, both of which have high incidences of private tutoring and low-school-quality levels, varies widely among schools, and many of the school process variables (e.g., the use of remedial classes, amount of school homework, frequency of tests, and the use of grouping by ability) account for the relationships with private tutoring.

凝聚学科智慧引领专业创新——教育技术学与学习科学基础研究的对话

<教育传播与技术研究手册>是教育技术领域专业人员不可或缺的大型工具书,该书2007年出版的第三版凝聚了全球教育技术专家的集体智慧,成为领域发展、学科建设的导航仪.本文从教育技术专业的立场对该书进行了评价,并与2005年出版的<剑桥多媒体学习手册>和2006年出版的<剑桥学习科学手册>进行了比较.论文对领域与学科的关系进行了较为清晰地阐述;在三大<手册>的比较中揭示了当代学习科学给教育技术学带来的挑战和机遇;在<教育传播与技术研究手册>三个版本的比较中揭示了教育技术学的现状与发展趋势.论文呼吁中国教育技术学者在借鉴国外成果的同时坚持自主创新,克服急功近利的浮躁,在与国际同行高层次、高水平的对话交流中把握领域与学科发展的历史、现实与未来,这是中国教育技术学走向成熟,走向世界的必由之路.     

State of University Library: Challenges and Solutions for Yemen

This study focuses on presenting the state of university libraries in Yemen, drawing upon observational research and in-depth interviews with 4 key university leaders, 12 teaching education program (TEP) chairpersons, 9 college deans, 6 vice-deans, 20 teaching professors, and 34 teacher training students within one higher education institution. The observational research has also covered five libraries of three private universities and two state ones. The findings outline the challenges faced by library users: the presence of traditional libraries, traditional resources and services, and the implementation of new policy. The study highlights the urgent need to redesign libraries, to increase libraries' budgets, and to establish digital resources and services, as well as a national library association.     

Media Coverage of Adolescent and Celebrity Suicides and Imitation Suicides among Adolescents

Suicide is the second leading cause of death among adolescents in the United States. Imitation plays an important role in adolescent suicides. Identification theory suggests that media coverage of adolescent suicides can increase imitation suicides among adolescents. The present study examines this possibility using data collected from South Korea. It also explores the relationship between media coverage of celebrity suicides and suicide rates among adolescents. We found that adolescent suicides increase after media coverage of either an adolescent’s suicide or a domestic celebrity’s suicide.     

Biocompatible chitosan/polyethylene glycol/multi-walled carbon nanotube composite scaffolds for neural tissue engineering

Carbon nanotube(CNT)composite materials are very attractive for use in neural tissue engineering and biosensor coatings.CNT scaffolds are excellent mimics of extracellular matrix due to their hydrophilicity,viscosity,and biocompatibility.CNTs can also impart conductivity to other insulating materials improve mechanical stability guide neuronal cell behavior and trigger axon regeneration.The performance of chitosan(CS)/polyethylene glycol(PEG)composite scaffolds could be optimized by introducing multi-walled CNTs(MWCNTs).CS/PEG/CNT composite scaffolds with CNT content of 1%,3%,and 5%(1%=0.01 g/mL)were prepared by freeze-drying.Their physical and chemical properties and biocompatibility were evaluated.Scanning electron microscopy(SEM)showed that the composite scaffolds had a highly connected porous structure.Transmission electron microscope(TEM)and Raman spectroscopy proved that the CNTs were well dispersed in the CS/PEG matrix and combined with the CS/PEG nanofiber bundles.MWCNTs enhanced the elastic modulus of the scaffold.The porosity of the scaffolds ranged from 83%to 96%.They reached a stable water swelling state within 24 h,and swelling decreased with increasing MWCNT concentration.The electrical conductivity and cell adhesion rate of the scaffolds increased with increasing MWCNT content.Immunofluorescence showed that rat pheochromocytoma(PC12)cells grown in the scaffolds had characteristics similar to nerve cells.We measured changes in the expression of nerve cell markers by quantitative real-time polymerase chain reaction(qRT-PCR),and found that PC12 cells cultured in the scaffolds expressed growth-associated protein 43(GAP43),nerve growth factor receptor(NGFR),and class IIIβ-tubulin(TUBB3)proteins.Preliminary research showed that the prepared CS/PEG/CNT scaffold has good biocompatibility and can be further applied to neural tissue engineering research.     

Teachers’ stages of concern for media literacy education and the integration of MLE in Chinese primary schools

Media literacy is an essential skill for living in the twenty-first century. School-based instruction is a critical part of media literacy education (MLE), while research on teachers’ concerns and integration of MLE is not sufficient. The objective of this study is to investigate teachers’ stages of concern (SoC), perceived need, school context, and teacher practices of the integration of MLE in primary schools. For this purpose, a survey was setup and 392 primary school teachers participated in this study. The results show that teachers’ concerns of integration of MLE were generally oriented at the level of self-concerns. In the meanwhile, the integration of MLE was significantly related to teachers’ concerns and perceived need for MLE. Based on the results of regression analysis, teachers’ integration of MLE was significantly influenced by their SoC for MLE, school professional development support, and leadership support.
