浅析市民新闻

随着传播技术的不断发展,人类的传播空间进一步扩大。受众不再仅是信息的接受者,也是信息的传播者。新闻传播不再是记者的特权,而是每个人的权利。市民新闻在这样的背景下应运而生,本文通过分析市民新闻产生的背景、原因及其特征,来探析市民新闻。     

《扬子晚报》新闻评论的平民化

《扬子晚报》的"扬子时评"版是该报最有特色的部分。"扬子时评"刊登的新闻评论能够站在百姓的立场,关注社会热点,褒贬现实,满足社会和公众的需求。本文分析了《扬子晚报》如何从平民角度出发,发挥舆论引导和舆论监督职能,及政府与群众之间的纽带作用。     

新闻档案“把关”中存在的问题及对策

新闻成为新闻档案,这个过程中存在一定的价值判断,从传播学角度来看,这是"把关人"进行"把关"的具体体现。信息化时代的今天,新闻档案工作在面临新发展机遇的同时,也产生了许多问题。厘清问题、找出对策,对提升"把关"水平、促进新闻档案事业健康持续发展具有重大的现实意义。     

舆论监督切莫成新闻逼视——以京华时报农夫山泉“标准之争”为例

舆论监督是新闻媒体的一项重要职能,新闻逼视则是一种新闻失范行为。舆论监督如果吃不透情况、抓不准问题、把握不好度,极易演变成新闻逼视。打铁还需自身硬。只要摆正立场不失理性、扮演好角色不越位、把握好平衡不过度,新闻逼视是完全可以避免的。     

当代“新闻反腐”的伦理困境研究

随着近年来社交媒体的兴起,"网络"成为反腐利剑,"网络反腐"也进入了学术界视野。然而,我们必须反思一个现实,即报纸、电视等传统新闻的舆论监督功能延伸至"反腐"领地时,往往选择性失明,从而产生"新闻不反腐"的伦理质问。从媒介伦理出发,可以发现传统新闻在"反腐"中陷入重重困境。     

商业网站与新闻网站专题比较研究——以新浪网和新华网“雅安地震”专题为例

本文主要运用观察法和内容分析法,对以新浪网为代表的商业网站和以新华网为代表的新闻网站关于同一新闻事件"雅安地震"所制作的新闻专题进行研究,分析其各自在整体构思、内容编排和页面设计等方面的特点。并在此基础上,针对各自的弱点提出对做好网络新闻专题的相关建议。     

数据新闻:大数据时代新闻的变迁——以网易、搜狐、腾讯、新浪的数据新闻为例

与传统新闻相比,数据新闻是"在事实本身之上进行深入的挖掘而获得表面事实背后蕴涵的故事",其生产过程包含五个方面:新闻选题、收集数据、处理数据、可视化、故事化。本文分析了网易"数读"、搜狐"数字之道"、新浪"图解天下"、腾讯"数据控"等栏目的数据新闻,并随机选取网易70篇数据新闻对网易"数独"产品进行分析后发现,网易的数据新闻基于大量的数据进行新闻挖掘,"社会生活"为题材的新闻居多,而且大都用圆形类图标进行可视化呈现。     

新闻评论应具有科学精神

由于历史原因使得新闻评论在人们印象中存在辛辣、犀利等"刻板印象",而随着时代的发展,社会现象变得越来越纷繁复杂,特别是在涉及众多科学知识的新闻事实面前,对新闻人、新闻评议人的科学精神提出了新的要求。本文通过对新闻评论的内容和形式的分析,浅析新闻评论应具有的科学精神。     

河北出炉年度十大环境新闻 半数与大气污染相关

正据河北省环保厅透露,该省2013年度十大环境新闻出炉,其中"河北省绿色崛起发展理念"居首,而"铁腕治霾"、"机动车限行"、"10292名大气污染防治义务监督员上岗"等半数新闻事件与大气污染相关.官方称,河北把工业转型升级和环境治理作为攻坚战,并出台相关意见,认为河北要崛起只能是"绿色崛起",新的增长极只能是绿色增长极.据介绍,在为期3个月的以查非法排污、超标排污、恶意排污为内容的"三查"行动中,该省共出动5.6万人次,     

浅谈新闻众包的内容生产

作为UGC的一种形式,新闻众包的出现是对"传者中心论"的有力回击。本文对新闻众包给新闻内容生产带来的变革以及新闻众包中的角色转化与认知进行论述,并提出新闻众包实施中可能会遇到的一些问题以及应对措施,认为新闻众包对于未来的新闻传播活动来说未尝不是一种有益尝试。     

焦点访谈特点分析

中央电视台1994年推出的《焦点访谈》栏目开创了我国电视新闻评论发展的新路子,并很快成为受众一致认可的名牌节目。在新闻评论课教学中,分析《焦点访谈》栏目的特点,总结栏目成功经验,对于学生更好地理解电视新闻评论很有必要。     

The ductus venosus in early pregnancy and congenital anomalies

The ductus venosus (DV) is a tiny vessel leading oxygenated blood from the placenta to the fetal heart and its flow assessment has been used as an indicator of fetal acidemia. At 11 to 14 weeks, the fetuses with increased nuchal translucency also showing an abnormal DV blood flow were consistently found to be aneuploid. Early cardiac dysfunction, signaled by abnormal DV blood flow, was suggested as the underlying cause of increased nuchal translucency. Detection rates for aneuploidy with the use of DV blood flow studies range from 59 to 93% with 2 to 21% false-positive rates. In fetuses with normal karyotype, an abnormal DV flow pattern signals cardiac defects or adverse perinatal outcome. Copyright © 2004 John Wiley & Sons, Ltd.     

DV在环境影响评价工作中的应用

环境影响评价工作是我国建设项目环境管理制度之一,近年来环境影响评价在很多领域渗透很快,对于如何提高环境影响评价工作效率和质量的问题,已经摆在许多环评机构和单位面前.随着信息时代扩张速度的加快,先进的科技工具也被应用到环境影响评价领域中,DV也是如此,DV在环境影响评价工作开展过程中的现状调研、公众参与、档案管理等阶段发挥很多重要的功能,使环评工作便捷、方便,对减轻工作强度,提高环境影响评价质量有很大的帮助.     

Citizen science for policy development: The case of koala management in South Australia

Citizen science involves the engagement of non-scientists in scientific research. Citizen science projects have been reported to be useful in policy development but there is little detail of how projects have contributed. The citizen science project, the Great Koala Count (GKC) collected ecological data about koalas and social data that have been used in the initial stages of the development of a South Australian Government koala management and conservation policy. After the GKC, we conducted an online survey of people who participated in the project and a control group. The survey focussed on opinions towards possible management options for koalas in South Australia. GKC participants were also asked about project-related changes in knowledge and opinions. We received 970 valid surveys and found some differences in opinions between GKC participants and the control group. Therefore, the GKC did not provide a representative sample of the entire South Australian population. However, we contend that the data from the citizen scientists are still valuable for policy development as it has been provided by people who are highly engaged in the topic (koala management in this case). It can be difficult to engage the public in the policy development process, and the citizen science project enabled the collection of a wide range of opinions, helping to discover and define relevant issues. Additionally, many people learnt about koalas and koala-related management issues, and some changed their opinions regarding koala management, also useful outcomes from the project in the policy development context. Our findings suggest that citizen science is useful for policy makers because projects provide the opportunity for dialogue with the people most interested in the topic of the project.     

对环保宣传的思考

随着世界环境的恶化,加强环保宣传变得愈加重要和紧迫.环保宣传既要考虑宣传的目的要求,又要符合新闻传播的规律,其在宣传内容、形式、受众、情境及宣传者等方面的特殊要求值得研究.环保工作者和新闻工作者应探讨解决我国环境报道目前存在的一些问题,以促进环境报道的健康发展.     

房地产开发与公民环境权保护的问题及对策分析

近年来,房地产过度开发以及相关房地产环境法律制度的缺失对公民环境权带来了极大的挑战。为了切实保护公民固有的基本权利——公民环境权,在房地产开发领域,应对房地产开发中公民环境权问题进行法律思考,并秉持“预防为主”、公民居住利益优先、消费者保护和利益协调衡量原则,实现人与自然的和谐发展。     

浅论影视拍摄活动环境影响评价

早在1978年,我国就针对影视业对环境的影响进行了研究,但只限于对电影洗片废水提出了具体的法规-<电影洗片水污染物排放标准>.而在我国目前现有的环境影响评价法律、法规中,影视拍摄这一项目不存在于需要进行环评的目录中,环保部门对这类行为的监管缺乏法律依据,直接导致了<无极>等事件的发生,引发了一系列的问题.本篇文章从拍摄活动与一般建设项目以及一般非污染生态项目的区别与相似之处对影视拍摄活动的施工期环境影响评价、拍摄期环境影响评价及拍摄结束后期的生态恢复工作做出分析并提出对策.     

Investigation of exhaled pollutant distribution in the breathing microenvironment in a displacement ventilated room with indoor air stability conditions

This study experimentally studied the dispersion of exhaled pollutant in the breathing microenvironment (BM) in a room equipped with a displacement ventilation (DV) system and indoor air stability conditions (i.e., stable and unstable conditions). The vertical temperature differences and the carbon dioxide (CO₂) concentration in the BM were measured. Results show that when DV is combined with the stable condition (DS), pollutant tends to accumulate in the BM, leading to a high pollutant concentration in this region. Whereas, when DV is combined with the unstable condition (DU), pollutant diffuses to a relatively wider area beyond the BM, thus the pollutant concentration in the BM is substantially reduced. Moreover, increasing the flow rate can reduce the pollutant concentration in the BM of the DS but yields little difference of the DU. In addition, personal exposure intensity increases with time, and the DS has a relatively higher increase rate than DU. The results suggest that indoor air stability will affect the performance of DV systems. DS will lead to a higher health risk for people when they stay in the indoor environment with pollutant sources, and DU is recommended for minimizing pollutant level in the BM in order to reduce the pollutant concentration and providing better air environments for the occupants.     

电视、中波发射塔对电磁辐射环境的影响

通过对包头市城区历年的电磁环境监测,以及电视和中波发射塔周围电磁辐射情况,了解其环境质量状况和主要污染源。历年环境监测综合场强为0.30~0.47 V/m,年平均值为0.41 V/m。而广播和电视发射塔因距离而异,它们综合场强均值分别为1.26~3.43 V/m、1.44~5.34 V/m。虽然这些监测值都在标准限值之内,但可以看出广播和电视发射塔对电磁辐射综合场强的影响极大。     

Regional news portrayals of global warming and climate change

In this study we utilize content analysis techniques to examine how the issue of global warming and climate change has been characterized during the period of 1992 through 2005 by the Houston Chronicle—the largest regional newspaper in the Texas coastal region. A total of 795 global warming and climate change news articles from the Houston Chronicle are collected, coded and analyzed. Data analyses are organized and presented with regard to issue salience, various issue attributes (issue image, scope, linkage, participant, proposed solution and responsible party), use of science, and scientific information sources cited in the news stories. We find that regional media attention to the global climate change issue generally increases over time and an overwhelming majority of the news articles view the issue as a harmful problem. However, given the scientific consensus that global warming will result in significant devastating climate change consequences to the coastal regions, there are still a fair number of news articles delivering mixed, undetermined or even non-harmful messages. We also find that climate change is often discussed as a national or international-global issue, and frequently linked to a number of other public issues rather than just being viewed as an environmental–ecological problem. Moreover, we find that emphasis on issue solutions is placed more on mitigation strategies than on adaptation behaviors, and that both governmental and non-governmental actions and responsibilities are suggested for dealing with climate change. In addition, our findings indicate that the regional newspaper in Texas obtains scientific information on climate change primarily from academic institutions. Implications of our findings and recommendations for future research are discussed in the concluding section.
