Coronavirus disease(COVID-19):The need to maintain regular physical activity while taking precautions

The on-going Coronavirus disease(COVID-19)outbreak in China has become the world's leading health headline and is causing major panic and public concerns.On January 30,2020,the World Health Organization(WHO)declared that the new coronavirus outbreak is a public health emergency of international concern.1 The virus has already had a direct impact on more than 10 million people in the city of Wuhan and has reached other parts of China as well,posing a health threat of unknown magnitude globally.As of February 8,2020,WHO reported 34,886 confirmed cases of COVID-19 globally,with 34,589 of them occurring in China(including 6101 severe cases and 723 deaths).A total of 288 other confirmed cases(with 1 death)have been reported in 24 countries,including Japan,Australia,Germany,and United States.2 However,these daily estimates are expected to rise even higher as reports from health authorities in China3 are gathered and near real-time updates of the Johns Hopkins virus dashboard are made 4 The outbreak has caused governments in various countries to take swift and protective measures.In China,these included putting cities on lockdown,5 implementing travel wamings/bans and cancellations,6 extending national holidays,and closing schools and postponing classes7.  相似文献   

基于决策树模型的幼儿超重关键因素研究     

吕文娣  赵广高  付近梅  孙顺利  陈晶  何梓豪  黄婷  胡超  陈晨 《成都体育学院学报》2020,(1):86-93

目的:基于决策树模型探讨引起幼儿超重的关键因素。方法:招募南昌市23所幼儿园5870名3~6岁幼儿,测量身高、体重;问卷调查幼儿身体活动、静坐行为、出生信息,父母的育儿方式、身体形态、锻炼行为和家庭情况,并将其划分为36个变量;采用IBM SPSS modeler软件创建CHAID决策树模型,筛选幼儿超重的关键性因素。结果:CHAID模型准确率达85.23%。CHAID模型结果显示,8个变量与幼儿超重有较强关联性,各变量按重要性排序依次为室外身体活动时间、父亲BMI、母亲BMI、父亲收入、室内身体活动时间、父亲受教育程度、喂养方式、看电视时间。结论:身体活动尤其是室外身体活动与幼儿超重的关系最为密切,父母肥胖程度、父亲收入与受教育情况、喂养方式、静坐行为也是导致幼儿超重的关键性因素。  相似文献

气膜厚度对反气泡稳定性的影响     

安骥  何随龙  王鑫  陈磊  李根  郑洪 《上海海事大学学报》2020,41(1):111-115

为观察气膜厚度对反气泡稳定性的影响,通过加热反气泡内外溶液来加热气膜内气体从而改变气膜厚度。实验发现:在一定温度范围内,加热反气泡气膜可以延长其稳定时间,但是当加热反气泡气膜使其厚度超过其稳定存在的阈值时,反气泡的稳定性会急剧下降甚至无法产生反气泡;在一定温度范围内温度对溶液表面张力影响很小,这使得文中实验数据合理化。本文为反气泡稳定性的理论研究提供实验支持,并考虑到气膜厚度为微米级,可为微米级气膜传热提供实验素材。  相似文献   

Projectification of Doctoral Training? How Research Fields Respond to a New Funding Regime     

Marc Torka 《Minerva》2018,56(1):59-83

Funding is an important mechanism for exercising influence over ever more parts of academic systems. In order to do so, funding agencies attempt to export their functional and normative prerequisites for financing to new fields. One essential requirement for fundees is then to construct research processes in the form of a project beforehand, one that is limited in time, scope and content. This article demonstrates how the public funding of doctoral programs expands this model of project research from experienced academics to the socialization process for the new academic generation. This process of “projectification” underlies funding-driven institutional changes in doctoral training. A multi-level comparative study of German policies, funding mechanisms and organizational frameworks for doctoral training demonstrates the emergence of a specific model of predefined PhD projects. The investigation of doctoral training practices reveals that socio-epistemic preconditions regulate whether research fields adopted or rejected this demanding model. This result contradicts widespread claims about a radical change in doctoral training and suggests focusing on the actual practices of field-specific doctoral research.  相似文献   

Ownership,organization structure and public service provision: the case of museums     

Enrico E. Bertacchini  Chiara Dalle Nogare  Raffaele Scuderi 《Journal of Cultural Economics》2018,42(4):619-643

This article provides an empirical investigation of the effects of the ownership and organizational structure on the performance of cultural institutions. More specifically, we consider how museums are effective in their function of disseminating culture to audiences and contributing to the local development. By exploiting a unique data set based on the 2011 census of Italian museums, we develop performance indices of accessibility, visitors’ experience, web visibility and promotion of the local cultural context. Using count data models, we regress such measures on the type of organization. We distinguish between governmental museums, public museums whose administration is either outsourced or has financial autonomy and private museums. We control for the most salient characteristics of a museum, competition pressure and some proxies of potential audience. Our evidence shows that private museums, public museums with financial autonomy and outsourced museums outperform public museums run as sub-units of culture departments. This paper contributes to the cultural economics and public policy and administration literature by adding insights into the effect of outsourcing and administrative decentralization in the public cultural sector.  相似文献   

Effects of the “Gangnam Style Syndrome” on the South Korean stock market     

Hyun Joung Jin  Jang-Chul Kim 《Journal of Cultural Economics》2018,42(1):139-161

This study attempts to answer two questions. First, can a single cultural event impact the stock prices of a wide range of companies and sectors? Second, was the positive stock market response in the information technology (IT) sector as well as performing arts sector significant? To answer these questions, we examine whether a hit pop single, “Gangnam Style” by Park Jae-Sang in 2012, affected related sectors of the Korean stock market and whether market reactions went beyond the stock price of the singer’s agency to affect those of other firms. We use an event study approach. The results show two notable empirical findings. First, although the findings indicating abnormal returns and cumulative abnormal returns appear mixed, the overall results imply that the unprecedented worldwide hit single by the South Korean singer positively affected the Recreation & Culture and Digital Content sectors. In other words, the market interpreted the event as good news, with shareholders expecting positive effects on the related sectors. Second, a positive stock market response was observed in the IT sector as well.  相似文献
