幼儿园教师公正:一道艰难的必选题

幼儿园教师公正是指教师在保教工作中体现出来的公平正义.教师的保教行为不能没有公正.公正是教育的应有之义,是促进教师发展的内在要求,是促进幼儿成长的重要因素.公正的践行受制于主观教育素养、客观教育资源以及教育氛围等多种因素.公正的实现需要教师个人、行业与园方以及社会共同作出努力.     

To name or not to name: a cross-cultural comparison of on-air attribution in US and Chinese TV news

This study investigates the Sino-US difference in the journalistic practice of providing on-air attribution for those interviewed in television news. Through a content analysis, this study compares how CBS News, a premier US TV network, and CCTV, China's most watched network, attributed their interviewees with on-screen name credits (names, titles and affiliations). The findings show that US journalists were more likely to provide on-screen name credits than their Chinese colleagues who, in turn, were more likely to give credits to interviewees who were older, male and government officials. This study should contribute to a better understanding of how cultural values and political ideologies may affect the way interviewees are treated in television news.     

Evidence-Based Medicine and the Development of Medical Libraries in China

This article elaborates on the opportunities and challenges that evidence-based medicine (EBM) has posed to the development of medical libraries and summarizes the research in the field of evidence-based medicine and achievements of EBM practice in Chinese medical libraries. Issues such as building collections of information resources, transformation of information services models, human resources management, and training of medical librarians, clinicians, and EBM users are addressed. In view of problems encountered in EBM research and practice, several suggestions are made about important roles medical libraries can play in the future development of EBM in China.

ENSO and Southeast Asian biomass burning modulate subtropical trans-Pacific ozone transport

Trans-Pacific transport of enhanced ozone plumes has been mainly attributed to fossil fuel combustion in Asia in spring, but less attention has been paid to vegetation fires in Asia. Here we show that the El Niño-Southern Oscillation (ENSO)-modulated fires in Southeast Asia, rather than Asian fossil fuel plumes, dominate the interannual variability of springtime trans-Pacific transport of ozone across the entire North Pacific Ocean. During El Niño springs, the intensified fires from both the Indochinese Peninsula and Indonesia, together with large-scale circulation anomalies, result in enhanced ozone plumes that stretch over 15 000 km in both the lower-middle and upper troposphere. This enhancement is also observed in the in situ measurements of ozone concentration, with an almost 10% increase at Mauna Loa Observatory, Hawaii, a unique site to monitor the long-distance transport over the North Pacific. This study reports an unexpectedly strong influence of vegetation fires, linked with climate variability, on global tropospheric chemistry and proves once more how complex the interactions in the climate system are.     

The Communication Anxiety Regulation Scale: Development and Initial Validation

A series of studies present the development and validation of the Communication Anxiety Regulation Scale (CARS), a self-report measure designed to assess the use of emotion regulation strategies to manage acute communication anxiety—in contrast to measures of general emotion regulation tendencies. Study 1 delineates the item derivation and selection process that yielded the final 12 CARS items. Results of an exploratory factor analysis supported the existence of four distinct subscales, each representing one of four anxiety regulation strategies (suppression, reappraisal, avoidance, and venting). Study 2 confirmed this factor structure and also examined correlations of the CARS with existing measures in an attempt to establish concurrent validity. Finally, Study 3 presents results of an item-sort task demonstrating the scale’s face validity and items’ substantive validity. Overall, findings provide preliminary support for the utility of the CARS as measure of communication anxiety regulation to be used by communication and psychology researchers.     

罗马法中的亲子关系与古代中国法亲子关系之比较

亲子关系,即父母子女关系,历来受国家法律的重视。罗马法和古代中国对此作了较为详细的规定。二者都认为,家父权是亲子法的核心,均强调家长具有至高无上的权力。只不过,在罗马法中,亲子关系是从私法上予以规制的;而古代中国亲子关系多以刑法的面目出现。这种"亲本位"的亲子关系和近代的"子女本位"的亲子关系均不适合现代社会的发展,我国应该有"社会本位"之亲子法。
