Analysis and optimization of assembly variations for non-rigid parts

Traditional variation analysis methods are not applicable to non-rigid assemblies due to possible part deformation during the assembly process. This paper presents the use of finite element methods to simulate assembly deformation. The relationship between the parts＇ variation and the variation of the key points in final assembly for quality control is set up by calculating the spring back deformation after assembly. Moreover, the optimization method for non-rigid assembly variations based on finite element analysis is presented. The optimal objective is to reduce the manufacturing cost. The approach is implemented by using ANSYS and MATLAB. The test example shows that the proposed method is effective and applicable.     

新媒体时代党的群众工作有效性探究

以互联网为主体的新媒体时代的兴起促使党的群众工作方式随之而转变,也使新媒体时代党的群众工作具备了新的特点。新媒体时代党的群众工作也存在着群众工作与新媒体时代发展不相适应、党的群众工作理论体系不完善、新媒体管理法规缺失等问题。探寻在新媒体时代开展群众工作的长效机制成为了亟待解决的课题。     

“全民健身计划”与高校体育

即将出台的全民健身计划是体育改革的一个重大举措，它将对我国群众性体育活动的开展产生重大影响。全民健身计划的重点是学校后体育（国外称大众体育，我国称群众体育），从宏观看，高校处于学校走向社会的转折点。本文从研究全民健身计划出台的背景，主要内容以及提高对全民健身计划的认识着手，探索高校体育为全民健身计划的逐步贯彻落实，必须抓好高校体育教学目标的转移，教学重点的调整，教学考核内容的改革，并建议采取相应措施。     

广东省群众性体育赛事发展困境与路径研究*

采用文献研究法与访谈法，通过实地调研，对广东省群众性体育赛事发展进行了研究。研究认为：伴随着全民健身的热潮，广东省群众性体育赛事发展步入了快车道，但在快速发展的同时，也存在不少问题。目前广东省群众性体育赛事遭遇政府机构管理分散，纵向协作能力较差；赛事供给特色不足，运作模式有待提升；市场调控能力较弱，缺乏法律保障制度等困境。为此，广东省应当立足于粤港澳大湾区，依托大湾区优势，形成湾区效应，加快建立整体性协调机构，打造“一站式”服务系统；深入挖掘广东省独有的历史文化资源和自然资源，打造特色品牌活动；从立法方面为群众性体育赛事提供制度保障，建立有效的激励和约束机制。

B2C Mass Customization in the Classroom

The purpose of this article is to describe an internet‐based mass customization assignment in Operations Management/Supply Chain Management classes where students utilize the Web site of a company that offers a customized product. Students evaluate the user interface, judge the value proposition of the product they demonstrate, and discuss issues of product design, process design and scheduling, inventory management, Supply Chain Management, marketing, and competitors. The students learn about mass customization from both the producer's perspective and the consumer's perspective. Through their own research and the class presentations students are able to develop a better understanding of the implementation requirements and challenges of mass customization. The assignment is highly interactive and has been successfully used in Operations Management and Supply Chain Management courses at under‐graduate and graduate levels and at multiple universities. In addition, practitioners interested in implementing a mass customization process can use the assignment as a brainstorming or benchmarking exercise.     

Predictors and Consequences of Conversations About Health Promoting Media Messages

Female college students (N=104) in friendship dyads were exposed to radio advertisements promoting the HPV vaccine—narrative or advocacy in format—after which they completed a questionnaire. Half the dyads were instructed to engage in a conversation about the advertisement prior to completing the questionnaire. Analyses showed that interpersonal discussion was related to normative perceptions, attitudes and intentions regarding the vaccine, but only under certain conditions. Conversation partner, conversation valence and positive opinion sharing were related to those outcomes. In a follow-up questionnaire, participants who discussed the ad in the days after exposure reported more positive intention change. Participants with stronger emotional reactions to the ads were more likely to discuss them during this period.     

四川高等教育强省战略的目标研究

伴随高等教育大众化的推进,四川已跨入高等教育大省的行列。面对建设人力资源强国和创新型国家的新形势,四川省政府做出了＂科教兴川,人才强省＂的发展战略,建设高等教育强省成为大众化阶段四川高等教育发展所面临的新任务。建设高等教育强省,必须持续推进高等教育大众化进程,不断提升高等教育发展水平,努力促进各级各类高等教育协调发展,全面提高高等教育质量和办学效益,切实增强高等教育服务经济社会发展的能力。高教强省战略的实施,将四川实现从高教大省向高教强省的跨越,推动四川经济社会又好又快发展,促进＂和谐四川＂建设。     

Does fake news affect voting behaviour?

We study the impact of fake news on votes for populist parties in the Italian elections of 2018. Our empirical strategy exploits the historical variation in Italian-speaking and German-speaking voters in the Italian region of Trentino Alto-Adige/Südtirol as an exogenous source of assignment to fake news exposure. Using municipal data, we compare the effect of exposure to fake news on the vote for populist parties in the 2013 and 2018 elections. To do so, we introduce a novel indicator of populism using text mining on the Facebook posts of Italian parties before the elections. Our findings support the view that exposure to fake news favours populist parties regardless of prior support for populist parties, but also that fake news alone cannot explain most of the growth in populism.     

浙江省“双创”发展水平的综合评价及其影响因素分析

采用嫁接的层次分析法-决策试验与评价实验室方法（AHP-DEMATEL）对浙江省的“双创”发展水平进行综合评价与比较，并采用面板回归方法就其影响因素进行实证分析，研究结果表明，（1）2010—2019年，浙江省整体的“双创”发展水平在不断提升，并且浙江省内各地区的“双创”发展水平呈上升之势。其中，杭州的“双创”综合指数最高，宁波的“双创”综合指数居全省第2位，而舟山的“双创”综合指数最低；浙江大湾区内的“双创”水平要高于全省平均水平，同时也高于浙江大湾区外的平均水平。（2）信贷规模、工资水平、互联网发展水平以及道路基础设施等因素均有利于浙江省“双创”发展水平的提高。相较而言，信贷规模和互联网发展水平更加有利于浙江大湾区内的“双创”发展，工资水平和道路基础设施则更有利于浙江大湾区外的“双创”发展。
