中国初创期电视新闻形态及其开创的传统

历史的演进总要指向特定鹄的,初创期(1958-1965年)的中国电视新闻固然有着形式简陋、内容单一等问题,却在理念和实践上对后世的发展产生了深远的影响。中国电视新闻的传统并未因"文革"而出现断裂,早期电视新闻在对《新闻简报》的播放和大量实况转播实践中形成的关于电视新闻的纪实与美学的风格与功能的种种理解,均对中国电视新闻的后续发展产生深远的影响。对早期电视新闻形态的深入考察,也有助于我们对中国电视新闻后来的变迁历程、当下的发展路径及其产生的社会影响有更加深入的理解。     

Assessing university students' perceptions of their Physics instructors' TPACK development in two contexts

Technological Pedagogical and Content Knowledge (TPACK) has been gaining traction among educational researchers; however, studies documenting university students' perceptions of their teachers' TPACK remain limited. This study intends to investigate the professional development of two physics instructors through the lens of the TPACK framework. Moreover, this study spans an 18‐week semester within both the contexts of Taiwan and China. Multiple data were collected and analyzed, including the pretest and posttest TPACK surveys, instructor interviews, in‐class observations and students' feedback and opinions. The results revealed that John's instructional representations and strategies and technology integration and application scores increased significantly, as well as Mike's knowledge of students' understanding score showing a significant increase from the middle to the end of semester. John (Taiwan) emphasized life examples and the use of multimedia while Mike (China) chose to emphasize students' knowledge and evaluation. Such results showed different teaching characteristics in the two contexts. Implications and suggestions are put forward based on the results of this study.     

Investigating the synergy of critical thinking and creative thinking in the course of integrated activity in Taiwan

The relationship lying between critical thinking and creative thinking is opposite or complementary, results of previous relevant researches have not yet concluded. However, most of researches put the effort to compare the respective effect of the thinking methods, either the teaching of creative thinking or that of critical thinking. Less of them showed the interest to investigate the combined effect of these two thinking skills teaching, especially its synergy. Therefore, present study aimed to discuss the synergy of critical thinking and creative thinking, and investigated the joined effect of these two methods of thinking in the courses of ‘Integrated Activity courses’. Not only the separate influence but also the synergy would be our interests. Moreover, the outcome would also be compared with the learning result of single creative thinking skill teaching. Participants were 147 male students and 118 female students of ninth grade from 8 intact classes in a public middle school in Taiwan, the number of total participants were 265. Experimental design was ‘nonequivalent control group pretest/post-test quasi-experimental design’. Participants were assigned into three groups, three intact classes for creative thinking teaching group (EG1), three intact classes for ‘critical thinking and creative thinking combined teaching group (EG2)’ and two intact classes for regular teaching method group (watching video, control group). All participants took the assessment ‘The New Creative-Thinking Testing’ and ‘The Critical-Thinking Testing, Level 1’ after receiving the courses as post-test. Data were analysed statistically by one-way ANCOVA. The results showed that:

1. Regards to the performance in Integrated Activity courses, no significant difference was found among students in EG1 and those in EG2. However, the students in both experimental groups got higher scores than those in control group did.

2. As for the ability of critical thinking, students in EG2 got higher score than those in EG1 and CG did, but no difference was found among the students in EG1 and those in CG.

3. In respect of originality, students in EG2 got higher score than those in EG1 did, the influence of critical thinking was significant.

Theoretical and possible applications of the results were also discussed. Present study not only manifests the correlation between creative thinking and critical thinking, but also provides the empirical data for synergy in actual pedagogical situations.

On-chip assay of the effect of topographical microenvironment on cell growth and cell-cell interactions during wound healing

Wound healing is an essential physiological process for tissue homeostasis, involving multiple types of cells, extracellular matrices, and growth factor/chemokine interactions. Many in vitro studies have investigated the interactions between cues mentioned above; however, most of them only focused on a single factor. In the present study, we design a wound healing device to recapitulate in vivo complex microenvironments and heterogeneous cell situations to investigate how three types of physiologically related cells interact with their microenvironments around and with each other during a wound healing process. Briefly, a microfluidic device with a micropillar substrate, where diameter and interspacing can be tuned to mimic the topographical features of the 3D extracellular matrix, was designed to perform positional cell loading on the micropillar substrate, co-culture of three types of physiologically related cells, keratinocytes, dermal fibroblasts, and human umbilical vein endothelial cells, as well as an investigation of their interactions during wound healing. The result showed that cell attachment, morphology, cytoskeleton distribution, and nucleus shape were strongly affected by the micropillars, and these cells showed collaborative response to heal the wound. Taken together, these findings highlight the dynamic relationship between cells and their microenvironments. Also, this reproducible device may facilitate the in vitro investigation of numerous physiological and pathological processes such as cancer metastasis, angiogenesis, and tissue engineering.     

新《档案法》实施背景下社会力量参与档案事务的路径选择与制度保障

鼓励社会力量参与档案事务,既契合新《档案法》的立法导向,也是档案事业走向依法治理、走向开放、走向现代化的内在要求。为了更好地引导和支持社会力量参与档案事务,促进档案事业的社会化发展,建议从参与档案资源建设、档案资源开发、档案外包服务、档案志愿服务、档案宣传教育和档案工作监督六个方面探索社会力量参与档案事务的路径,并从细化档案法律内容、落实信息公开制度、完善运行管理制度、强化责任监督制度、创新奖励激励制度五个方面加强社会力量参与档案事务的制度保障。     

一流科技期刊“刊域共建”现状及策略分析

为了解一流科技期刊的“刊域共建”情况,文章从2019年度和2020年度“中国科技期刊卓越行动计划”入选项目中选取医药卫生类期刊,从期刊基本特征、分布、主办单位、发表内容、出版平台等方面进行分析,探讨入选该项目的期刊对学科领域发展的作用,以及“刊域共建”的内容和效果。结果显示:医药卫生类期刊是重点发展对象,亟需通过国际化、高起点的期刊提升学科竞争力和话语权;期刊的主办单位可以集合资源联动学科领域建设,在刊发内容上通过聚焦交叉学科、填补学科空白、策划前沿选题、应用双语发表等引领学科发展;学科本身的知识更迭也为期刊发展提供了源动力。由此提出,通过“刊域共建”带动一流期刊建设,同时促进学科发展,实现两者的良性联动。     

图书馆教育研究在中国的双向学科化走势

图书馆教育研究伴随着图书馆事业、图书馆学的发展而兴盛起来.由于对象范围的逐渐分化,图书馆教育研究近年来在中国出现了双向学科化走势,初步形成图书馆教育学的两门主干分支学科—图书馆专业教育学和图书馆社会教育学.为了更好地推进这两门学科的可持续发展,当前需要对两者做整体协同性思考,包括把握两门学科的亲缘关系、强化两门学科的始端开发、加固两门学科的共同基础.
