鸡传染性喉气管炎的诊治研究

对自然发病鸡群进行病毒分离、鉴定。通过人工感染发病的方法,研究了发病鸡的临床症状和病理变化,同时对试验病鸡进行了不同药物的治疗试验。结果表明,根据临床症状和病理变化只能做出初步诊断,确诊必须进行病毒分离。试验用的所有抗生素对治疗均无作用,中药穿心莲粉有较好的疗效。     

公共危机中的谣言:认知判断、功能分析与治理路径

伴随公共危机的发生,谣言总是相生相伴.对于谣言,人们往往把它与虚假信息紧密地联系在一起.但是,无论是从谣言定义的理论阐释,还是对危机谣言传播的实证分析,都不约而同地发现,谣言所传递的信息,未必完全虚假,有些谣言不仅信息真实,而且还回应着公共危机的特殊情境,之于公共危机而言也未必完全是消极影响.因此,对于谣言,尤其是公共危机中的谣言,人们应该做到客观判断、双重认知;对于公共危机中的谣言治理,也需要采取辩证思维,在寒蝉效应与言论自由之间寻求平衡.     

对《印度之行》中回声的多角度探寻

本文以后殖民主义理论作为支撑,从不同的角度解读了《印度之行》中的回声之谜。由于山洞和回声的含义都过于含蓄,且福斯特竭力运用似乎真实的自然现象去容纳过多的含义,因此山洞和回声不仅使英国游览者而且也使读者感到混乱和神秘。本文旨在从多角度解读回声,以进一步启发读者思考。

当代中国首脑出访与周边外交

自新世纪以来,周边外交在中国总体外交布局中被赋予首要地位,而首脑外交是这一地位的具体体现.根据我国现阶段的政治制度,中国的"首脑"是指中共中央政治局常务委员会全体成员,首脑出访也就是"九大常委"的出访活动.从2003年至2009年七年间,与受访的其它国家相比,中国首脑出访周边国家呈现了出访次数多,出访的稳定性和持续性强,出访安排上具有优先性,参加周边地区多边国际会议和重点庆典活动多等特征.通过首脑的出访,可以看出当代中国周边外交的特点:地缘政治的特殊考量决定了周边外交在当代中国首脑出访中的特殊地位;坚持双边外交与多边外交并重,全面、深入、广泛地开展全方位周边外交;首脑出访务实高效,经济外交空前活跃;致力于周边地区经济发展与和平稳定,彰显负责任大国形象.     

Understanding public perceptions of genetically modified organisms in China: The role that heuristics play during digital media exposure

This study explicates the role that heuristics play in influencing Chinese public perceptions of genetically modified organisms (GMO) when they are exposed to digital media. According to the cognitive–affective continuum of heuristics, trust in scientists and negative emotions about GMOs are a cognition-oriented heuristic and an affect heuristic, respectively. The statistical results of an online survey (N?=?414) demonstrated that trust in scientists fully mediated digital media exposure and perceptions of the risks versus benefits of GMOs. In addition, negative emotions moderated the full mediation effect, showing that the indirect effect was stronger in individuals with low levels of negative emotions than in those with high levels of negative emotions. The mediating role of trust in scientists and the moderating role of negative emotions, the two heuristics applied in this study, indicated that when negative emotions were weak, laypeople were more likely to rely on scientists to judge the consequences of GMOs than systematically process the associated information by themselves. The findings have implications for reconsidering the importance of heuristic processing in building reasonable public perceptions of risk-laden technologies through the digital environment.     

Joint modelling of longitudinal binary data and survival data

The medical costs in an ageing society substantially increase when the incidences of chronic diseases, disabilities and inability to live independently are high. Healthy lifestyles not only affect elderly individuals but also influence the entire community. When assessing treatment efficacy, survival and quality of life should be considered simultaneously. This paper proposes the joint likelihood approach for modelling survival and longitudinal binary covariates simultaneously. Because some unobservable information is present in the model, the Monte Carlo EM algorithm and Metropolis-Hastings algorithm are used to find the estimators. Monte Carlo simulations are performed to evaluate the performance of the proposed model based on the accuracy and precision of the estimates. Real data are used to demonstrate the feasibility of the proposed model.
