本文基于2010-2018年10600起舆情事件,考察了事件本身属性、媒介传播、网民参与及政府干预对网络舆情热度的影响。多元分层回归模型的结果表明:1.环境和文化体育类事件网络舆情热度较高,反腐倡廉类事件网络舆情热度较低;因为大型活动和科技发现引发的舆情事件传播热度较高。2.由传统媒体、网络新闻首次曝光的舆情事件热度较低。3.出现第三方、网络谣言、网络动员的舆情事件热度较高,意见领袖的出现对网络舆情热度没有显著影响;网民舆论倾向性非常正面的舆情事件传播热度较高。4.网络舆情事件中如果国家部委进行了干预,则舆情热度较高;政府干预的时效性越差,网络舆情热度越高;政府采用新闻发布会、社交媒体回应的舆情事件热度较高,利用对外公告或文件回应的舆情事件热度较低;政府干预级数与网络舆情热度正相关。 相似文献

The approach of context collapse and the notion of unintentional context collisions are of importance to scholars of social media. Israeli public hospitals are a particularly suitable venue for studying these topics, as they employ both Jewish and Arab practitioners, who care for both Jewish and Arab patients amid an ongoing violent conflict. In-depth interviews were conducted with 50 managers and healthcare practitioners (physicians and nurses), both Jewish and Arab, employed at 11 public hospitals in Israel. We found that despite hospitals managements’ instructions to avoid political discourse, it erupts nonetheless whenever the conflict escalates. Fearing damage to professional relations and care of patients, political discourse spills over into social media, where political opinions are expressed mostly by Arab practitioners and stereotypical attitudes against Arabs are expressed mostly by Jewish ones. Our study exemplifies the usefulness of the context collapse approach—and specifically unintentional context collisions—to work organizations and all the more so to healthcare organizations. 相似文献

In light of the increasing importance of citizen-centricity in public services, one approach technologically advanced public organizations take is to integrate proactivity into their services. Scholars agree with the potential for proactivity in public services and study some aspects of the topic, and some publications deal with the concept of proactivity itself. However, opinions regarding the characteristics of proactive public services diverge in both research and practice, and despite—or maybe because of—the growing body of research, the literature still lacks conceptual clarity. We address this issue by developing a taxonomy for proactive public services using Nickerson, Varshney, and Muntermann's (2013) taxonomy-development method. Using eight empirical and conceptual iterations that draw on a structured literature review, two semi-structured interviews, investigation of 67 real-world objects, and an evaluation with nine potential users, we propose a taxonomy of eight dimensions and 23 characteristics. The outcome of this work enriches scientific knowledge about digital government by detailing the concept of a proactive public service and serving as a basis for further research. Moreover, practitioners can be inspired by the 23 characteristics of proactive public services to identify possible next steps in the design of their services, such as determining which proactive public services are feasible and in what form. In addition to the taxonomy, our collection of 67 practical examples of proactive public services from a variety of countries contributes to digital government research and practice. 相似文献

政府形象传播与民意互动 总被引：4，自引：0，他引：4
政府形象传播的指向虽然是社会公众 ,但其本质是处理民意 ,也就是了解民意的实质 ,判断、预测民意的走向和后果 ,为政府施政既创造有利的民意环境 ,又扭转不利的民意环境。民意以社会普遍和整体的认识 ,准确揭示周围环境的内在联系和现实世界的发展趋势。政府既要学会从舆情中察民情、识民意、知民心 ,更要做到及时调整政策 ,顺民意 ,合民心。善于驾驭和把握舆论的方向、善导民意是政府成熟的标志 相似文献

More than 5,000 households with a person identified as having a physical, mental, or emotional condition that impairs participation in activities were surveyed about their opinions concerning barriers to public library use and opinions about efforts by public libraries to be useful to people with disabilities. Results showed that perceptions of accessibility, collections, and presence of assistive or adaptive devices for people with disabilities were slightly more positive if someone in the household had used the public library in the past year. Data used for the study were from the October 2002 Current Population Survey, a federal survey conducted by the U.S. Census Bureau for the Bureau of Labor Statistics. 相似文献

Social media can be used to assess public opinions and emotions during different stages of a crisis. Guided by the Crisis and Emergency Risk Communication (CERC) model, this study examined a systematic sample of 2,881 tweets from a corpus of over one million tweets posted during the initial, maintenance, and resolution stages of the 2015 California measles outbreak. It found that the public showed the greatest interest (as measured by the number of tweets and retweets) in the initial stage of the crisis, but their interest drastically declined afterward. The expression of humor/sarcasm was significantly more frequent in the initial stage than in the maintenance or resolutions stage, while the expression of reassurance increased significantly from the initial, maintenance, and resolution stage. The emotion of alarm/concern was most frequently expressed during the initial stage. For message types, the public were more likely to tweet about their personal opinions and less likely to tweet about resources during the initial stage. These findings allow public health professionals to better design messages in response to the public’s concerns and emotions during public health crises. 相似文献

This paper explores the role of perceptions of the opinionsof others as they relate to the formation of public opinion.Two interrelated theories involving such perceptions, the thirdperson effect and the spiral of silence, are tested in the contextof public opinion regarding divestment of financial interestsin South Africa. As hypothesized by the third person effect, perceptions of theinfluence of media reports on others were found to be consistentlygreater than perceptions of influence on self. Findings werestrongly supportive of this component of the ‘third personeffect’ hypothesis. Perceptions of the opinions of otherswere also explored in relation to respondents' willingness toexpress their opinions publicly. As suggested by the spiralof silence theory, respondents were found to be more willingto express their opinions publicly when they perceived a trendin support of their viewpoint, or when there was a greater perceivedlikelihood of achieving success for their issue position. The size of the effect produced from joining these two processesis moderated by the role of issue salience. People perceivingdivestment as a highly important issue are more likely to ascribegreater media influence to others than to themselves, but theirwillingness to express their opinions publicly is least likelyto be influenced by perceptions of the climate of opinion. 相似文献

Controlled vocabulary and subject headings in OPAC records have proven to be useful in improving search results. The authors used a survey to gather information about librarian opinions and professional use of controlled vocabulary. Data from a range of backgrounds and expertise were examined, including academic and public libraries, and technical services as well as public services professionals. Responses overall demonstrated positive opinions of the value of controlled vocabulary, including in reference interactions as well as during bibliographic instruction sessions. Results are also examined based upon factors such as age and type of librarian. 相似文献

In biology and medicine, a scientist’s legend is most commonly determined by their sphere of influence, either on surrounding peers, on clients in the case of medical practitioners, or on the wider scientific public in the case of research scientists. A scientific paper still constitutes the most effective portal through which ideas, knowledge and opinions can be shared among academics and scholars. Thus, legends in science are built upon a scientist’s published literature. Legend was always assumed to be safe in its final form, i.e., a published paper. Yet, a powerful movement of post-publication peer review has begun to identify that not all has been well with the vetting process that led to the publication of a tranche of the scientific literature, and that editorial oversight and weakness has prevailed in a number of cases, leading to retractions and a more critical re-assessment of the literature. One could say that the half-life of a scientific paper has only just begun once it is published. Within this context of science publishing that has given a sense of false security, legends may evolve from boom to bust within the space of weeks or even months. The legendary status of a scientist is therefore no longer safe if there are hidden or undiscovered errors, fraud or misconduct. 相似文献

真实、完整、及时的信息来源,是科学决策的基础。其中,舆情信息对于领导决策必不可少。舆情,是指民众对管理者的某些政策、制度和施政行为及有关社会现象所持态度的舆论。舆情是发布者思想的反映,不同程度地影响接受者的思想和行动,而且舆情能够在传播过程中产生共振放大效应,形成更大的群体压力。因此,对舆情的及时掌握、科学分析和妥善处置,考验着各级政府及其领导干部的执政能力。文章着重研究图书馆在舆情监测分析中的功能优势。 相似文献
