Changes in Risk Perceptions Prospectively Predict Changes in Self‐Reported Speeding

Risk perception theories posit that changes in risk perception prompt subsequent changes in risk behavior. Prospective studies using observations made at three time‐points offer the capacity to test this hypothesis by observing sequential changes in both risk perceptions and behavior. A telephone survey was administered by random‐digit dialing to 255 adult Australian drivers at baseline (T1), 6 weeks (T2), and 14 weeks (T3). During weeks 2–5, a risk‐perception‐based anti‐speeding mass media campaign was conducted. The survey assessed risk perception, operationalized as the proportion of time that driving at 70 km/h (43 mph) was perceived to be dangerous, and self‐reported speeding behavior, defined as the frequency of respondents driving 5 km (3 mph) faster than the legal speed limit in built up areas. Higher T2 risk perception predicted lower T3 self‐reports of speeding after controlling T1 risk perception and T1 and T2 self‐reported speeding. This can be interpreted as changes in risk perceptions between T1 and T2 predicting changes in speeding between T2 and T3. Further analyses showed that increases in risk perception predicted lower subsequent self‐reported speeding changes, but decreases in risk perception were unrelated to those changes. Risk perception changes were unrelated to recall of exposure to the media campaign. These findings support a dynamic view of the relationship between risk perception and self‐reported behavior, and that risk perception theories can be applied to speeding.     

The impact of newsroom changes and the rise of social media on the practice of media relations

Recent changes in American media have resulted in direct impacts on the work of PR professionals, from newsroom reductions in traditional media outlets to the rise of social media. This study examines changes in the media relations dynamic with qualitative, in-depth interviews from 12 PR professionals in a medium, eastern U.S. city. Findings include PR professionals doing less traditional media relations, mostly attributable to downsized newsrooms, and frustration with the resulting dearth of institutional knowledge, influx of young, inexperienced reporters, and shallow stories. While participants see opportunities to inject unfiltered messages in media, overall they value reporter relationships and using social media in communication with them and in their job. Although new media are seen as one more task on an already very full PR plate, participants acknowledge their importance and growing relevance. Overall, PR professionals see their and the industry's future including both traditional and new media.     

批判与反思后的流变和敛缩——“五四”文坛感伤情调的历史走向

“五四”时期，“感伤”情调作为一种重要的精神标记，以浪漫主义文学阵营创造社为中心向整个文坛弥漫开来，并在风行一时之后，因其滥情倾向而受到新月派为主的批判；以蒋光慈为代表的革命作家则发展了一种浪漫的“革命感伤”，并最终受到革命阵营的批判而走向敛缩。创造社在时代感召下和深刻反思后也以积极态度告别个人感伤，走向了革命的欢呼。     

电子媒介如何影响社会行为——梅罗维茨传播理论述评

美国传播学者梅罗维茨是媒介分析领域的一个代表人物,他结合麦克卢汉的媒介技术决定论和戈夫曼的剧场理论,指出电子媒介是通过改变社会的情境从而影响了人们的行为方式,比如外在体现为男女性别的融合、成人与儿童的模糊以及政治人物的祛魅等方面.本文还针对其理论进行评析.     

新形势下高校校园传播媒体运作模式的建构

校报、有线广播、校园计算机网络等构成了现代高等学校校园传播媒介的主体,在高校的育人工作中发挥着重要作用,它们有着各自的特点和优势,但也存在着资源互通和整合不够的问题,制约了整体作用的更大发挥.面对信息时代的机遇和挑战,要充分发挥校园传播媒体的舆论导向、服务教育和娱乐休闲等功能,推动校园人际关系的良性互动,营造良好的育人环境,改变媒体间各自为政的局面,关键是构建高效、有序、统筹的高校校园传播媒体运作模式和机制.

习近平新时代中国特色社会主义思想研究动态与前景展望

自十九大报告提出"习近平新时代中国特色社会主义思想"以来,学者们从形成背景、理论渊源、发展历程、逻辑内涵、重大意义等维度,对其进行了多个层面的研究阐释,取得了比较丰硕的研究成果,为今后贯彻落实这一思想提供了重要基础。但是仍需看到,由于这一思想正式提出时间不长,学者们研究时间有限,现有研究成果难免存在一些不足之处,主要有四个方面:整体性研究有待提高,实证研究有待加强,跨学科研究有待拓宽,国际视野有待扩展。     

党内政治文化与党的政治建设：逻辑、问题与路径

党内政治文化作为政党文化的一个组成部分,与党的政治建设是相互联系、相互促进的。党的政治建设是发展党内政治文化的有效载体,为建设优秀党内政治文化提供必要条件和保证;党内政治文化建设是党的政治建设的根本要求,为党的政治建设提供精神支撑和价值引领。在中国特色社会主义的新时代和新征程中,我们党仍然面临着复杂的执政环境和各种影响党的先进性、弱化党的纯洁性的复杂因素。因此,必须将发展党内政治文化融入党的政治建设全过程,充分发挥党内政治文化对新时代党的政治建设的作用。
