Chaos theory, informational needs, and natural disasters   总被引:2,自引:0,他引:2  
This study applies chaos theory to a system-wide analysis of crisis communication in a natural disaster. Specifically, we analyze crisis communication during the 1997 Red River Valley flood in Minnesota and North Dakota. This flood, among the worst in modern American history, consumed entire metropolitan areas, displacing thousands of people. The conditions and decisions leading to the disaster, and the subsequent reactions are retraced. Communication related to river crest predictions (fractals), the shock at the magnitude of the crisis (cosmology episode), novel forms of reorganizing (self-organization), and agencies that aided in establishing a renewed order (strange attractors) are evaluated. Ultimately, we argue that preexisting sensemaking structures favoring rationalized, traditional views of a complex system led officials to make inappropriately unequivocal predictions and ultimately diminished the effectiveness of the region's crisis communication and planning.  相似文献

This study explores the interplay of sex, presence, and enjoyment of nonfictional tragic news content; an experiment was conducted in which participants viewed a news story about Hurricane Katrina's devastation to the Gulf Coast on a standard definition television, high definition television, or a video iPod. The results indicate that women reported more sadness regardless of condition, though they seemed especially moved in the iPod condition. Women also reported more information seeking, and reported highest levels of presence in the iPod condition. The results are discussed both in terms of implications for crisis message practitioners, and in terms of what the results may mean for our understanding of the enjoyment of tragedy.  相似文献

In response to Hurricane Katrina's extensive destruction and related public health threats, the Centers for Disease Control and Prevention (CDC) deployed more than 1,000 staff to its emergency operations center and to affected areas. Among them were members of CDC's Emergency Communication System. This paper describes the strategies and tactics used by health communication specialists during the pre-event, response, and post-event stages to address a range of emergency communication exigencies. It highlights three difficult challenges for CDC communication specialists during Hurricane Katrina: rapid dissemination of health messages; adaptation of health messages for diverse audiences, locations, and circumstances; and phasing of key risk messages during the emergency response.  相似文献

This study presents the IDEA (internalization, distribution, explanation, action) model as an easy-to-use and situationally generalizable framework for quickly developing effective messages instructing people on how to protect themselves before and during high-risk events, crises, disasters, and other emergencies. The model consists of four elements: helping message recipients internalize the potential impact of the risk or crisis event, identifying appropriate channels and strategies for distributing the risk or crisis event messages, offering a brief and intelligible explanation of the nature of the risk or crisis, and providing specific self-protective action steps for people to take. The model may be used to design messages in any risk, crisis, or emergency context. Through a posttest-only quasi-experimental cross-sectional research experiment, this study measured the perceived message effectiveness, cognitive understanding, and behavioral intentions of those viewing a television news story about a crisis situation employing the IDEA model compared to those viewing a similar story replicating typical crisis event news stories delivered to general publics. This comparative examination revealed that the message designed according to the IDEA model was significantly more effective than the status quo message and resulted in greater behavioral intentions to engage in appropriate self-protective actions in the event of an acute risk or crisis situation. Strategies for implementing the model are also provided.  相似文献

暴发于2019年末并迅速发展的新冠肺炎疫情已成为全球性的公共卫生事件。本研究开展于大众媒体信息尚且不充裕的疫情早期,通过对全国32省(自治区、直辖市)243市1265名受访者的在线调查,考察疫情初期人们在媒体使用、疫情感知和个体行为等方面的总体情况。研究显示,人们对新媒体(微信公众号和微博)的使用频率明显高于传统媒体,而对其可信度评价却显著低于传统媒体。个体风险感知和社会风险感知构成了公众对疫情风险感知的总体估量,且人们对疫情的认知和行动彼此关联。受社交媒体使用和参与的影响,个人层面风险感知指向更积极的人际传播;受大众化媒体使用和信息获取的影响,社会层面的风险感知则更多的导向抽象的疾病知识和符合社会利益期待的个体行为。  相似文献

This study applies the critical paradigm of “rhetorical enterprise” to the case of nineteenth‐century British reform efforts, particularly the organization and the “gospel” of the Birmingham Political Union, and concludes that cases of rhetorical enterprise challenge critics to account for the enterprising consistency of tactics and creed regardless of the relatively inconsistent factors of men andevents.  相似文献

This study explores how audiences seek information from social and traditional media, and what factors affect media use during crises. Using the social-mediated crisis communication (SMCC) model, an examination of crisis information and sources reveals that audiences use social media during crises for insider information and checking in with family/friends and use traditional media for educational purposes. Convenience, involvement, and personal recommendations encourage social and traditional media use; information overload discourages use of both. Humor and attitudes about the purpose of social media discourage use of social media, while credibility encourages traditional media use. Practically, findings stressed the importance of third-party influence in crisis communication and the need for using both traditional and social media in crisis response.  相似文献

Contemporary information seekers can acquire health information from an unprecedented variety of sources. The reported study applied and extended channel complementarity theory to explain the use of multiple information sources in the health-information-seeking process. Channel complementarity was extended to consider four characteristics (i.e., access to medical expertise, tailorability, anonymity, and convenience) of health-information sources. The information-seeking behavior of 3,392 respondents from the 2007–2008 Health Information National Trends Survey was analyzed to test study hypotheses. Results indicate that, sources were used complementarily based on tailorability and anonymity during health-information sources. Additionally, the likelihood of using complementary sources based on all four characteristics changed during the search process.  相似文献

The current study investigates how social media affordances influence individuals’ source credibility perceptions in the presence of risk information, specifically examining how bandwagon heuristics interact with different identity heuristics at the individual level. The MAIN model and warranting theory serve as the theoretical framework to examine the effects of bandwagon cues and identity cues embedded in retweets and users’ profile pages for health and risk online information processing. A posttest-only experiment with a self-report questionnaire was administered to participants. Results indicate that different online heuristic cues impact the judgments of competence, goodwill, and trustworthiness. Authority cues strongly influenced source credibility perceptions. A reverse-bandwagon effect was observed in influencing source credibility judgments.  相似文献

In recent years, government agencies on all levels and in all branches have increasingly engaged in harmonizing business processes, standardizing information sharing, and interoperating their information systems, which indicates a rising need for intra- and inter-government collaboration. Simultaneously, the technical capacity for process integration, information sharing, and system interoperation/interoperability (INT-IS-IOP) has also greatly increased. While a number of INT-IS-IOP projects have faced serious challenges leading to problematic project outcomes, other projects have produced the desired results. Using the amended Scholl/Klischewski (2007) framework this study systematically analyzes documents of nineteen cases of mostly successful projects, which were carried out across Europe. Based on the results of this analysis, we identify and document key foci and characteristics of successful projects. The comparative case analysis also helps assess the explanatory power of the Scholl/Klischewski framework, its applicability to practice, and its utility for evaluative purposes.  相似文献

The Web-at-Risk project is a digital preservation project funded by the Library of Congress as part of the National Digital Information Infrastructure and Preservation Program. The project is developing a Web archiving service to enable curators to build, store, and manage archived collections of Web-published materials captured largely from U.S. federal and state government agency Web sites. In 2005 the project’s 22 curators, as well as librarians and archivists working primarily in academic libraries (n = 43), university researchers (n = 7), and content providers (n = 7) participated in a study to identify their needs in relation to Web archiving. This paper summarizes the issues and challenges these groups face and discusses the need for collaborations among libraries and government entities for preserving Web-published materials.  相似文献

In recent years, the need to understand and identify effective data-driven strategies for the communication challenges faced by schools associated with school shootings has become paramount. The current study reports findings from 10 face-to-face interviews conducted with school crisis team members at the P–12 level who experienced school shooting events. The findings, which extend discourse of renewal theory, identify six primary communication-related challenges that districts face postcrisis and offer effective strategies for overcoming these challenges.  相似文献

Swearing is a frequent language form in a number of contexts, including the work setting. This investigation extends research on expectancy violations theory as an explanation for how people perceive swearing by examining violation valence. Study 1 concludes that violation valence is positively related to perceptions of message appropriateness and effectiveness and to perceptions of the speaker. Study 2 replicates these findings using a national sample. These results provide support for the role of expectancy violations in swearing and show that swearing is not always perceived as negative in work settings.  相似文献

Safe, clean water is necessary for health and well-being. Water issues affect minority and vulnerable populations at disproportionate rates, including the poor and racial and ethnic minorities. An investigation of the relationships of race, social media use, and informational sources during the municipal water crisis in Flint, Michigan, reflects an instrumental view of communication and uses and gratifications theory in this study. Data from 208 Flint residents in 2016 indicated that African American respondents favored interpersonal networks and resources and were more likely than other racial groups to obtain current information about the water crisis via Instagram. Preferred channels and sources to receive additional crisis information varied on the basis of race.  相似文献

This study analyzes the messages in hate group websites using a grounded theory approach. Through this process of interpretive inquiry we propose four prominent themes—educate, participate, invoke, and indict—that characterize the messages examined in 21 hate groups. These message themes speak to the: (a) education of members and external publics; (b) participation within the group and in the public realm; (c) invocation of divine calling and privilege; and (d) indictment of external groups including the government, media, and entertainment industries, and other extremist sects. In advancing a substantive grounded theory of online hate group communication, we also explore the potential of these themes to ostensibly reinforce the hate group's identity, reduce external threats, and recruit new members.  相似文献

Supervising agents serve as sources of social support for over one million women in the US on probation and parole who strive to avoid recidivism. Little is known about the supportive messages agents intend to provide their female clients or their precursors. The optimal matching model of social support is used in an investigation of the precursors to agents’ intent to send different types of social support messages to the women they supervise. Results indicated that supervising agents intended to provide informational support in the form of suggestions or advice, esteem support in the form of compliments, and emotional support in the form of encouragement to the women. Both agent communication pattern and offender level variables were precursors to the intent to send informational support messages, but only agent communication pattern variables predicted the intent to send emotional support messages.  相似文献
