Setting a Non-Agenda: Effects of a Perceived Lack of Problems in Recent News or Twitter

The mere perception that news has given certain problems more coverage can lead the audience to assume that those problems are more important. Given that the news media, at times, obsesses over relatively trivial matters, and given that the audience is increasingly able to filter media exposure, it is worth asking what happens when audience members perceive that recent media coverage has not emphasized any very important problems. In such cases, audience members might assume that any problems facing the nation must not be particularly important. We explicate this attitude of political complacency, test whether perceived media agendas lacking important problems can influence it, and explore whether complacency helps explain political disengagement. We also explore whether these effects generalize beyond news, to new media gatekeepers such as Twitter. Two experiments tested effects of a perceived absence of important problems in recent news or Twitter content. In the case of news, but not Twitter, this increased complacency in both studies. Study 2 added a no-exposure control and found that effects on complacency were driven by the cueing of nonproblem stories, not by the absence of problem story cues. Both studies validated complacency as a predictor of political disengagement.     

Impact of sports participation on mortality rates among Brazilian adults

Objective: To analyze the possible dose-response association between components of sports participation (intensity, volume and previous engagement) and 4-year mortality rates among Brazilian adults.

Methods: 679 males and females (mean age among men = 66.7 ± 9.3 years old and mean age among women = 64.8 ± 8.9 years old) composed the study sample. Sports participation was assessed using Baecke’s questionnaire, which considers intensity, duration and previous engagement. Medical records were used to identify the cause of the death. Cox regression analysis was performed to determine the independent associations of exercise components and mortality.

Results: Participants that reported exercising at moderate-vigorous intensity (Moderate/vigorous: 4.1% versus None/light: 10.3% [p-value = 0.012]; HR = 0.42 [0.1 to 0.94)] and for more than four months (≥4 months: 5.3% versus <4 months: 10.2% [p-value = 0.038]; HR = 0.47 [0.24 to 0.94]) had lower mortality risk. The percentage of survival according to all-cause mortality was significantly higher for participants engaged in sports at moderate-vigorous intensity (p-value = 0.014), as well as for those engaged in sports for periods superior than four months (p-value = 0.036).

Conclusion: We found higher percentage of survival among adults engaged in sports at moderate-vigorous intensity and with at least four months of previous engagement.     

学术文献引文上下文自动识别研究

[目的/意义] 引文内容分析能够帮助揭示文献引用关系的深层语义内涵,而引文上下文识别作为引文内容分析的基础显得尤为重要。[方法/过程] 梳理已有引文上下文研究的现状,总结当前引文上下文识别的不足,在此基础上归纳引文上下文识别的5类特征,并采用文本分类和序列标注两种方法开展引文上下文自动识别实验。[结果/结论] 实验结果表明,本文提出的特征能够很好地提升引文上下文识别效果,且基于文本分类的SVM分类效果要优于基于序列标注的CRF。

农村经济发展中的金融缺失与金融扶持

章以农村金融结构为研究对象，分析了目前农村中广泛存在的资金短缺现象及其形成机理。章认为：其一，国家实行的倾向性的发展战略是造成农村金融资源缺乏，金融扶持水平低下的基要因素；其二，始于20世纪80年代中期以来的地方政府与国家在金融资源上的恶性竞争则是加剧了这一现象的罪魁祸首。因此，要改变这一现象，就需要在国家发展战略的重新定位与寻求现行农村金融体制突破两方面着手。
