在技术叠代加速、社会变化加速、生活节奏加速的加速社会里,以播客为代表的听觉文化再度回归.从信息传播效率来看,声音表意对于时间的需求、数字口语的表达冗余、"低效"的去中心化内容分发机制,使播客成为"加速社会"里的"慢"媒介.从技术伦理视角来看,声音的情感陪伴、线性叙述下的意向完整表达、对传受双方的平等赋权,使播客建构的感官世界与意义空间有助于缓解加速社会带给人们的奴役压力.

线上教学是融媒体时代教学改革与发展的必然趋势.传媒类实验课程线上教学的展开,既需要突破场地、设备和器材的限制,也要实现教学个性化、动态化、多元化."平台+技术+资源"模式是实现这些目标的可行模式.推动这一模式可持续深化发展,需要培养教师信息技术的应用能力,重视屏幕外实验效果评估,兼顾教学资源相关主体利益,线上线下教学相互补充.

为掌握新疆、青海、甘肃、四川和西藏等西部5省区农牧民包虫病防控相关知识、态度和行为("知信行"),分析影响"知信行"水平的关键因素,对1213名农牧民进行问卷调查,用百分比描述"知信行"的每个条目,采用t检验或方差分析,比较不同人群的"知信行"水平差异.结果显示:西部5省区农牧民对包虫病防控相关知识的知晓率为57.0％,其中感染途径知晓率最低,为30.8％;55.6％的农牧民对包虫病防控持有积极态度,68.3％的农牧民对包虫病防控有较好的行为习惯.当地农牧民获取包虫病防治知识的途径多来自医生和传统宣传资料,分别占60.7％和48.2％,未来还希望通过电视、广播和网络等大众媒体获取.青海省农牧民以及文化程度初中及以上、民族为汉族的农牧民具有较高的认知水平.结果表明,西部5省区农牧民对包虫病的认知水平较低,获取相关信息途径较为单一.建议加大宣传力度,突出包虫病源头防控;利用当前主流新媒体,丰富宣传方式,使宣传内容、载体更加契合西部少数民族地区的生活和文化习惯,切实推进农牧民防疫意识和自我防护意识的提升.

Background: In China canine rabies poses a serious public health problem in that human mortality ranks the second highest globally. While rabies health education interventions are advocated by WHO to be critical components of modern rabies control and prevention programs, available studies have not adequately investigated the relative efficacy of their implementation in at-risk populations. This study aims to measure and compare the effect on knowledge and protective behavior towards rabies of health education interventions that include a novel Short Messaging Service via cell phone (SMS) and rabies health information sessions (IS).Methods: The study used a between-subject design involving repeated measures of rabies-related KAP (knowledge, attitude and practice). A total of 350 randomly selected villagers were randomly allocated into three intervention (SMS, IS and SMS + IS) and one control group. The content of SMS and IS covered topics about rabies prevention and route of transmission. The SMS intervention consisted of ten separate messages delivered three times two weeks after the pretest; the IS intervention was conducted once immediately after the pretest. A validated questionnaire was used to capture demographic information and KAP information. Ordinary Least Squares regression was used to contrast the effects of interventions.Results: Our results indicate that overall SMS outperforms IS at improving knowledge and protective behavior against rabies. Our results suggest that a combined intervention of SMS and IS can result in higher scores than any of the two in isolation. The impact of SMS, IS and SMS + IS is greatest on knowledge, followed by attitude and practice scores.Conclusion: This study demonstrated that health communication modes based on SMS, IS and a combination of the two are all effective to improve rabies-related KAP in the short term. These findings highlight the potential usefulness of SMS as an additional tool for public health communication and promotion; further studies are needed to investigate the long term benefits of these interventions on the reduction of dog bites and resulting human rabies incidence.

20世纪30年代,美国记者埃德加·斯诺来到中国,开展了13年的新闻采访活动,对中国革命和世界反法西斯战争进行了一系列的报道,其著作至今被中外记者誉为新闻报道的经典之作.斯诺的新闻成就一方面取决他始终践行了新闻专业主义,另一方面得益于他不畏艰难的新闻职业精神和致力于提升综合实力的思想理念.那么,斯诺的新闻思想对新世纪的新闻接班人有什么现实启示和指导价值？本文将通过定性分析的方法对这些问题进行探讨.
