加强我国公共卫生管理的若干建议

公共卫生是事关人民群众健康的公共事业,提供公共卫生服务、进行公共卫生管理是政府的重要职责。我国政府十分重视公共卫生事业发展,尤其是2003年"非典"疫情后,我国公共卫生服务体系建设不断完善、管理不断加强。但这次突如其来的新冠肺炎疫情发生与蔓延,仍然暴露出我国公共卫生管理的一些短板,亟待我们总结经验、深入研究,有针对性地采取措施加以解决。具体建议包括:(1)完善国家安全观;(2)强化法治建设;(3)强化政府治理能力建设;(4)健全信息公开、媒体与互联网管理制度;(5)强化专家的科学精神与职业素养;(6)健全突发公共卫生事件应急管理机制;(7)加强社会组织建设,完善社会力量参与机制;(8)提升公民应对疫情灾情素质;(9)切实把"预防为主"方针落到实处;(10)注重研究突发公共卫生事件期间的经济政策。     

大疫当前谈供应链思维：从“啤酒游戏”说起

2019年底暴发的新冠肺炎疫情是一次重大的公共卫生事件,它对我国乃至世界的社会经济都将产生巨大而深远的影响。遗憾的是,这样的事件已不再是百年一遇,而是十年一遇或更短的时间,因此如何有效地应对大规模传染性疾病的暴发是人类社会面临的十分重要而迫切的问题。这次新冠肺炎疫情既是一个不幸,也是一个难得的学习机会。通过对疫情防控过程的回顾,以及对在该过程中所遇到的一些困难的梳理,发现很多问题最终都可以归结为供需矛盾的问题,而供给侧的挑战通常又都源于供应链的无序和混乱。文章结合现代供应链管理理论的一些基本原理,对疫情防控工作进行了分析并给出了建议,如建立全国联网传染病监测中心、国家防控战略物资安全库存、国家突发事件应急管理指挥中心等。另外,疫后经济重建也至关重要,因此还从供应链思维的角度,分析了新冠肺炎疫情的行业影响,以及企业复工复产过程中应该注意的事项。

A new age for child protection--General Comment 13: why it is important, how it was constructed, and what it intends?

Children continue to be subjected to high levels of violence (i.e., physical, psychological and sexual maltreatment) throughout the world. International concern about violence against children has increased significantly during the last decade. A Study on Violence Against Children, encouraged by the UN Committee on the Rights of the Child, conducted under the auspices of the United Nations Secretary General and reported in 2006, has become a rallying call to improve child protection. Child protection practices and systems have been judged to be generally inadequate and, in some cases, destructive. It is widely recognized that business as usual—more of the same—will not do. A General Comment (guide to fulfilling obligations) for Article 19, the central conceptualization of child protection of the UN Convention on the Rights of the Child, has the potential to promote a worldwide reformulation of child protection priorities, policies, and practices by virtue of the infusion of a child rights approach. It can be a mechanism for framing and promoting the transformational change needed – for a genuine paradigm shift. Here, explication is given for the historical context, rationale, centrality of child rights, process of development, holistic nature, and primary elements of General Comment 13 (GC13): The child's right to freedom from all forms of violence. GC13 embodies and champions a child rights approach to child protection entailing strong support for proactive primary prevention, promotion of good child care, and a commitment to secure the rights and well-being of all children. A child rights-based, comprehensive coordinating framework is recommended for the implementation of GC13.     

第19届世界杯足球赛决赛阶段角球进攻战术研究

通过对第19届世界杯足球赛决赛阶段64场比赛628个角球空间特征研究发现：对时空间的利益诉求愈来愈强烈地成为现代足球比赛的显著特征。激烈的时空竞争使得角球进球成为高水平比赛制胜的关键。长传配合仍为角球进攻的主要空间组织形式;角球进攻空间轨迹以弧线球进攻为主,弧线球进攻形式中又以内弧线球进攻为主;内弧线球的运用数量以及成功率,都明显高于外弧线球;二次进攻成为外弧线球进球的另一有效进攻手段。角球进攻的空间区域主要集中在球门正面地带的近距离区域（1区、2区）内;1区进攻次数仅次于2区,但成功率却最低,进攻空间2区进攻次数最多,成功率也高于1区,但在进攻1区的成功射门对球门形成的威胁程度要远大于2区,本届世界杯关键比赛尤其如此。球门区域内的空间（1区）主要为内弧线球进球的空间区域;球门区域外空间（2区）主要为外弧线球进球的空间区域。后插上是角球进球的主要空间抢点方式,直接攻门成为进球得分的主要手段。

Untangling the contributions of meteorological conditions and human mobility to tropospheric NO2 in Chinese mainland during the COVID-19 pandemic in early 2020

In early 2020, unprecedented lockdowns and travel bans were implemented in Chinese mainland to fight COVID-19, which led to a large reduction in anthropogenic emissions. This provided a unique opportunity to isolate the effects from emission and meteorology on tropospheric nitrogen dioxide (NO₂). Comparing the atmospheric NO₂ in 2020 with that in 2017, we found the changes of emission have led to a 49.3 ± 23.5% reduction, which was ∼12% more than satellite-observed reduction of 37.8 ± 16.3%. The discrepancy was mainly a result of changes of meteorology, which have contributed to an 8.1 ± 14.2% increase of NO₂. We also revealed that the emission-induced reduction of NO₂ has significantly negative correlations to human mobility, particularly that inside the city. The intra-city migration index derived from Baidu Location-Based-Service can explain 40.4% ± 17.7% variance of the emission-induced reduction of NO₂ in 29 megacities, each of which has a population of over 8 million in Chinese mainland.

Higher education students’ achievement emotions and their antecedents in e-learning amid COVID-19 pandemic: A multi-country survey

The outbreak of the COVID-19 pandemic has had a wide range of negative consequences for higher education students. We explored the generalizability of the control-value theory of achievement emotions for e-learning, focusing on their antecedents. We involved 17019 higher education students from 13 countries, who completed an online survey during the first wave of the pandemic. A structural equation model revealed that proximal antecedents (e-learning self-efficacy, computer self-efficacy) mediated the relation between environmental antecedents (cognitive and motivational quality of the task) and positive and negative achievement emotions, with some exceptions. The model was invariant across country, area of study, and gender. The rates of achievement emotions varied according to these same factors. Beyond their theoretical relevance, these findings could be the basis for policy recommendations to support stakeholders in coping with the challenges of e-learning and the current and future sequelae of the pandemic.     

终身收入视角下学前教育中断的经济后果——基于疫情下“学习趋势”框架的全球估算

新冠疫情不仅是一场全球公共卫生危机,还广泛地产生经济和社会影响。依据“学习趋势”框架,选取联合国教科文组织新冠疫情应对小组、联合国教科文组织教育统计处、世界银行教育统计数据库中共170个国家与经济体的数据,构建终身收入视角下学前教育中断的中长期经济后果测算模型。结果显示,截至2021年10月31日全球学前教育中断实质造成相当约0.38个正常学年学习增量的直接损失,其对应人均终身收入损失约8.5万美元（2017PPP）,相当于成年后预期年均收入下降3.05%。在全球层面,中长期经济损失累计约21.1万亿美元（2017PPP）,其中欧亚大陆国家所承担的中长期经济代价将达全球损失一半以上。新冠疫情下,全球学前教育中断的影响是普遍且深远的,任何一个国家和区域都无法独善其身,各国应团结正视教育系统所面临的严重挑战,以实际行动恢复优质且连续的学前教育。
