对新闻评论是否具有政治性、指导性的考究

新闻评论作为新闻报道深化、拓展、延伸的重要手段,在媒体上起到了不可替代的作用,本文针对新闻评论是否具有政治性、指导性,从新闻评论的自身性质属性、社会时代的环境和媒介载体的特点三个方面来考究。     

论民生新闻评论中的批判性思维

批判性思维是一种特殊的思维方式.将批判性思维运用在民生新闻评论中可以使评论更加理性、更有深度.但是,如果我们错误地理解了这种思维方式而在实际运用中操作不当,就会使评论失去应有的作用,甚至会导致民生新闻的评论走向另一个极端,影响民生新闻整体的传播效果.本文强调了民生新闻评论中批判性思维运用的重要性,指出了批判性思维运用应避免的误区,探讨了正确运用批判性思维的方法.     

抓好社会新闻提升党报竞争力

社会新闻在媒体中有着极为广泛的读者群,党报作为我国大众传媒中的主流媒体,必须根据自身特点,将社会新闻做出质量,做出特色,从而进一步提升党报的竞争力。这就要求党报在价值取向和操作方式两个层面上形成自己的特色。     

提升地市级党报竞争力的有效手段

做大做强地市报,可以说是地市级党报每一位社长、总编辑孜孜以求的愿望。面对中央、省级强大媒体的攻势,同时还面临着晚报、都市报等生活类媒体的激烈竞争,要做大做强地市党报,必须从以下六个方面入手增强报纸的生存和发展能力。     

改进会议报道的一点思考

会议报道是地方党报新闻里的重要组织部分,是党报“喉舌”作用的集中体现。当前,会议报道存在着诸多问题,形成了固定的“会议八股文”模式,很难吸引读者。作为地方党报来讲,会议报道是绕不开的话题,会议报道不仅必须写,而且还要写得出彩,这样才能提高办报质量。改进会议报道势在必行,要跳出会议写会议,从读者的角度关注会议报道,要做会议中的“有心人”,挖掘会议中的新闻。     

浅谈新闻评论的写作

新闻评论的写作有其自身的特点,同新闻一样,新闻评论也要注重真实性和实效性;同时,新闻评论还肩负着促进民众交流与引导社会舆论的任务,要面向人民群众;新闻评论观点要深刻,直指问题的本质。     

融媒体时代新闻评论转型研究

新闻评论是新闻传播和社会舆论的主要方式,融媒体时代对传统的新闻评论提出了新的要求,需要进行创新性的改变才能适应新的发展趋势,本文立足融媒体时代新闻评论的特点,分析其受到的影响,并对其创新转型做出有益的探讨。在传统媒体发展时代,新闻评论是不可或缺的节目类型,成为传统媒体引领舆论走向的核心阵地。随着融媒体时代的到来和发展,传统新闻评论受到不同程度的影响和挑战,新闻评论也呈现出一些与以往不同的特点,新闻评论如何积极地去适应新媒体的发展需求,实现全新的转型,是急切需要深入研究的重大课题。     

平民化视角办地市党报的思考

地市级党报要增强其亲和力和影响力,就要从平民化视角,从百姓的立场,用百姓的语言,报道老百姓身边的新闻。替他们说出心里话。实现这一目标的路径主要有栏目设置平民化、做深做透民生新闻、策划和解读重大新闻等。党报平民化还要避免琐碎化、低俗化和过度娱乐化。     

Students' Reactions to the Introduction of Videoconferencing for Classroom Instruction

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors.     

Cooler temperatures inductive to locust outbreaks

Ajoint study by Prof. ZHANG Zhibin from the CAS Institute of Zoology and his co-workers from Norway, US and Swiss have indicated that historical outbreaks of migratory locusts in China were associated with cold spells, suggesting that China＇s projected climate warming could decrease the pest＇s numbers. The study was published in Proceedings of theNational Academy of Sciences on 17 September, 2007.     

Exploring Multiplexity: Social Network Structures in a Computer-Supported Distance Learning Class

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction.     

Low doses of a red wine ingredient figh diabetes in mice

Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said.     

The Role of Intermediating Institutions in the Diffusion of Electronic Data Interchange (EDI): How Industry Associations Intervened in Denmark, Finland, and Hong Kong

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies.     

How Electronic Publishers are Protecting Against Piracy: Doubts About Technical Systems of Protection

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means.     

Rough Justice: A Statistical Assessment of ICANN's Uniform Dispute Resolution Policy

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP.

Monoculture Rubber Plantations Have Negative Ef ects on Controlling Splash Erosion

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence
