A new regression model for bimodal data and applications in agriculture

We define the odd log-logistic exponential Gaussian regression with two systematic components, which extends the heteroscedastic Gaussian regression and it is suitable for bimodal data quite common in the agriculture area. We estimate the parameters by the method of maximum likelihood. Some simulations indicate that the maximum-likelihood estimators are accurate. The model assumptions are checked through case deletion and quantile residuals. The usefulness of the new regression model is illustrated by means of three real data sets in different areas of agriculture, where the data present bimodality.     

基于SEM-AHP方法的核电厂定量人为因素评价研究

文章基于人为因素分析与分类系统,分析了115起核电厂执照运行事件报告(Licensed Operation Event Report, LOER),并对影响核电厂事件发生的人为因素进行分类,采用结构方程模型方法得出各影响因素的路径系数,两两比较得到层次分析模型的判断矩阵,进而确定各因素的权重。同时对核电厂人为因素的重要性做排序分析,找到核电厂运行过程中的安全管理薄弱环节,从而促进核电厂系统平稳运行。     

Impact of support networks for breastfeeding: A multicentre study

Background

The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.

Varieties of political support in emerging democracies: A cross-national analysis

Political support is a multidimensional construct encompassing evaluations of political leaders and institutions (specific support) as well as adherence to basic regime principles (diffuse support). Scholars have traditionally assumed that diffuse and specific support are driven by different forces and evolve largely independently. Prior empirical work, however, has struggled to untangle the two support dimensions and focused predominantly on cross-national differences, ignoring their dynamics. This paper develops an analytical and empirical approach to examine the levels and dynamic interplay of both support dimensions and estimate their determinants, applying it to South American democracies between 1996 and 2015. Contrary to received wisdom, we show that both dimensions are quite volatile and closely linked in this region. In particular, negative economic shocks not only undermine support for government actors, but also fuel democratic disenchantment. Nonetheless, while regime support is rather fickle in South America, it can be ultimately resistant to performance fluctuations.     

互联网医疗服务法律监管研究

随着互联网技术的进步以及医疗改革的深入,互联网医疗服务成为新生业态.然而,我国互联网医疗服务法律监管体系还不够完善,缺乏统一规范的监管体系,多头监管、个人隐私隐患大、纠纷处理解决机制不健全等现实困境尚未解决,不利于互联网医疗服务行业的发展和人民群众身心健康.为解决上述问题,通过梳理发达国家的成功经验,如美国的移动医疗应用程序监管和个人隐私保护、欧盟的互联医疗数据管理、英国的行业协会监管等,结合我国现有国情,建议从完善立法体系、建设隐私保护机制、构建行业监管、明晰医疗服务主体责任等方面健全互联网医疗法律监管制度,以期推动互联网医疗服务行业发展,保障医患双方的合法权益.     

互联网时代媒体融合发展的未来模式探索

以互联网技术为引领的新技术为传统媒体的发展带来了新的机遇与挑战.从历史的角度看,传播媒介的发展轨迹与技术变革的历史脉络相互印合.媒体融合的层次与内涵日渐丰富,产业实践中呈现出复杂的博弈与协作关系.传统媒体独特的版权资源与人才储备优势,与新兴媒体的传播渠道及传播效率优势相结合,互相推动,深入协作,通过媒介融合渠道,实现优秀的人才、优质的内容与优化的传播平台的整合,以形成迸发式的传播威力,推动传播层次的迭代发展.面向技术发展前景的媒体融合,应当秉承开放与共享的新思维、立体与互动的新路径,注重以用户为中心,充分利用技术的便捷性,实现媒介传播渠道的多层次性与互动性,超越阶段性的固有技术模式,以踏准未来的节拍.     

新中国成立以来中国共产党对十月革命的纪念与政治话语的建构

新中国成立以来,中国共产党因国家和社会现实需要,不同时期对十月革命的纪念与阐释呈现出不同的主题.社会主义革命与建设时期,中国共产党借十月革命表达了在社会主义建设、中苏关系协调、社会主义阵营的团结和世界和平的维护方面的政治诉求.改革开放后,十月革命的纪念又为中国特色社会主义道路的探索建构起双向话语支撑,既明确了中国改革的政治方向,又建构了中国特色的社会主义话语.中国共产党对十月革命的纪念与阐释呈现出反对历史虚无主义、坚持服务现实、彰显主体意识的鲜明特点.中国特色社会主义道路不仅仅是对十月革命道路的坚持和继承,更是在新的时代条件下以中国为本位对这一道路的发展与创新.站在新的历史方位,中国共产党强调应坚定不移走中国特色社会主义道路.     

习近平新时代观的理论生成探讨

理顺习近平关于“中国特色社会主义进入新时代”的逻辑理路,有助于系统论证“新时代”的科学性和理论性。从方法论上看,习近平新时代观是应用马克思主义立场观点和方法得出的正确结论。从理论归因看,中国社会主要矛盾的转化作为习近平新时代观生成的主要标志,源于马克思主义关于矛盾运动的基本理论。从理论定位看,习近平新时代观展现的是中国发展的特殊阶段,内含着中国对自身发展的时代定位与目标趋向,渗透着中国与世界在共同发展中的新阶段、新高度、新未来,是对中国发展方向的顶层设计。
