Major Accidents (Gray Swans) Likelihood Modeling Using Accident Precursors and Approximate Reasoning

Compared to the remarkable progress in risk analysis of normal accidents, the risk analysis of major accidents has not been so well‐established, partly due to the complexity of such accidents and partly due to low probabilities involved. The issue of low probabilities normally arises from the scarcity of major accidents’ relevant data since such accidents are few and far between. In this work, knowing that major accidents are frequently preceded by accident precursors, a novel precursor‐based methodology has been developed for likelihood modeling of major accidents in critical infrastructures based on a unique combination of accident precursor data, information theory, and approximate reasoning. For this purpose, we have introduced an innovative application of information analysis to identify the most informative near accident of a major accident. The observed data of the near accident were then used to establish predictive scenarios to foresee the occurrence of the major accident. We verified the methodology using offshore blowouts in the Gulf of Mexico, and then demonstrated its application to dam breaches in the United Sates.     

It's Complicated: The 2014–2015 U.S. Measles Outbreak and Parents’ Vaccination Beliefs,Confidence, and Intentions

While it seems intuitive that highly visible vaccine‐preventable disease outbreaks should impact perceptions of disease risk and facilitate vaccination, few empirical studies exist to confirm or dispel these beliefs. This study investigates the impact of the 2014–2015 Disneyland measles outbreak on parents’ vaccination attitudes and future vaccination intentions. The analysis relies on a pair of public opinion surveys of American parents with at least one child under the age of six (N = 1,000 across each survey). Controlling for basic demographics, we found higher levels of reported confidence in the safety and efficacy of childhood vaccinations in our follow‐up data collection. However, this confidence was also accompanied by elevated levels of concern toward childhood vaccines among American parents. We then examined how different subgroups in the population scored on these measures before and after the outbreak. We found that parents with high levels of interest in the topic of vaccines and a child who is not fully upto date with the recommended vaccination schedule reported more supportive attitudes toward vaccines. However, future intentions to follow the recommended vaccination schedule were not positively impacted by the outbreak. Possible explanations for these results and implications for vaccination outreach are discussed.     

A class of partially linear transformation models for recurrent gap times

In this article, we propose a general class of partially linear transformation models for recurrent gap time data, which extends the linear transformation models by incorporating non linear covariate effects and includes the partially linear proportional hazards and the partially linear proportional odds models as special cases. Both global and local estimating equations are developed to estimate the parametric and non parametric covariate effects, and the asymptotic properties of the resulting estimators are established. The finite-sample behavior of the proposed estimators is evaluated through simulation studies, and an application to a clinic study on chronic granulomatous disease is provided.     

以习近平总书记“3·18”讲话为重要遵循 推进新时代思政课建设

习近平总书记在2019年3月18日主持召开全国学校思想政治理论座谈会并发表重要讲话，即“3·18”讲话。在“3·18”讲 话中，习近平总书记不仅强调了新时代我们“为什么”要办好思想政治理论课，而且明确回答了新时代我们要办“什么样”的思 想政治理论课和“如何办好”思想政治理论课等一系列重大问题。实践表明， “3·18”讲话是党中央新时代办好思想政治理论课 的重要遵循。在该讲话发表一周年之际，重温这一讲话具有重要理论和现实意义。     

历史文献学视野下的重大历史事件

重大历史事件的提出源于国家文艺创作政策,是重大历史题材的内核。从历史文献学的视角来看,重大历史事件的文献形态表现为本源事件、衍生事件和文本事件。重大历史事件的衍生特征主要体现为本源事件的内容选择性、视角多样性、衍生多态性和历史叙事的结构层次性。重大历史事件具有文献能产性,其根本动力来源于历史主体的社会认可需要、纪念活动的客观物证需要和文艺创作的传奇叙事需要。     

试论侯外庐以马克思主义唯物史观为指导的中国思想史研究

侯外庐的中国思想史研究在马克思主义唯物史观的基础之上，紧扣时代脉搏，继承中国文化的优良传统，对中西文化进行深入比较，探讨其异同。他冷静地钻研、不懈地思索，遵循严格的研究规范，提出了许多深刻的问题，在学术研究的过程中创立了一个史学学派，成为中国思想史研究的典范。     

论艾伦·伍德对资本主义民主的批判

艾伦·伍德基于历史唯物主义对经济和政治的连续性的分析,以民主为切入点,借鉴古雅典经济民主和政治民主相统一的洞见,揭示了资本主义民主的虚假性。伍德的观点既有助于我们认识资本主义民主的本质,也有助于我们从经济民主和政治民主相统一的维度重新思考社会主义民主,建构社会主义民主制度。     

No Expo Network: a failed mobilization in a post-political frame

In 2015 Milan hosted the Universal Exposition with the theme ‘Feeding the Planet, Energy for Life’. Even if characterized by various scandals and problems, the edition was narrated by the mainstream media as a political and economic success. Critical voices were almost completely obscured by favorable propaganda and the ideas of development and the future proposed by the Expo rhetoric was presented as inevitable, configuring ‘the best of all possible worlds’ in a more general post-political frame. In this profile I first present the main characteristics of the No Expo Network, e.g. the actors that composed it and the main critiques that they advanced. I will then focus on the reasons for its defeat, which is then contextualized in relation to the election of the Chief Executive Officer of Expo 2015 as new Mayor of Milan. Here, we can see the continuation and structural strengthening of the neoliberal politics of Expo2015 beyond the mega event itself.     

Establish a Glorious Century of Maintaining Life＇ s Dignity

现今的世界上,有许多人由于内战、贫困与饥饿、环境破坏等威胁,迫使他们的生命及尊严处于危险状态,也有大批人仍然饱受着人权侵害、种族歧视的痛苦。为和平、人权、人道的奋斗,绝不是低层爬到高山的顶峰就可以达到终点那样。重要的是要创建一股一代接一代、谁也阻挡不了的滔滔洪流,并日积月累地把它发展和扩大。这就是我们为了建设一个和平未来的不断挑战。     

初中起点幼师大学生历史课过度教学现象探析

一般而言，历史课及其任课教师是比较受初中起点幼师大学生欢迎的。与此同时，历史课教学中也时常不经意间在教学内容安排、教学方法运用和教学观点表达等方面出现过度教学现象。学生主体地位的异化，教学过程把控失当和教学反思的缺位，是造成过度教学的主要原因。消除过度教学现象的对策主要是坚持教学过程中学生的主体地位，掌握教学有度的艺术和重视教学反思。
