加强新形势下流动人口管理不断深化"三基"工程建设

加强流动人口管理服务工作,是"三基"工程建设的一项重要内容,也是当前经济转轨、社会转型特殊历史时期提高社会治安管理能力的有效手段。面对新形势、新环境、新任务,摒弃旧观念,着力研究、探索和创新流动人口管理服务的新举措、新方法,是摆在各级公安机关面前一个既现实又重要的课题。     

青年流动人口教育健康效应及群体差异研究

在“健康中国”战略背景下,如何更充分地发挥青年流动人口的健康人力资本效用,值得关注。本研究基于2014年流动人口动态监测调查社会融合专题调查数据,采用Logistic回归和OLS回归方法,就受教育程度对青年流动人口不同健康指标的影响进行了分析。研究表明：青年流动人口受教育程度由初中向高中提升能够促进正向健康自评,但高等教育加剧了健康随时间推移而变差的感知;女性、农业户籍、80后青年流动人口的健康状况更明显地受到受教育程度的影响。研究建议：通过缩小城乡教育质量差距、加强多元化心理健康支持、提高流动人口社会融合水平等举措,提升青年流动人口的人力资本质量,促进青年流动人口全面发展。     

管理与服务:流动人口治理工作的双飞翼

流动人口是当代社会关注的热点问题,加强对流动人口的管理刻不容缓.对于流动人口,既要加强管理,规范法律法规、管理手段、管理制度;又要强调服务,切实做好流动人口的权益保护工作,真正提高流动人口的社会地位.管理与服务并重,是目前流动人口治理工作的有效模式.     

A Comparison of Coronary Artery Stenosis Estimates Made by Forensic Pathologists and Medical Students

Previous studies suggest cardiovascular pathologists are less accurate than noncardiovascular pathologists (e.g., clinical pathologists) in estimating the degree of coronary artery stenosis. To further investigate the effect of training on accurate estimation of coronary artery stenosis, we designed a study to compare the accuracy of estimates made by forensic pathologists versus medical students. Six forensic pathologists and twelve medical students each independently examined 24 images of coronary artery cross sections and gave an estimate of the degree of stenosis. When comparing all 24 images, the forensic pathologists had a median difference between the estimated percentage of stenosis and actual percentage of stenosis of −12.380 and the medical students had a median difference of −16.50 (p-value of 0.08542). In estimating the percentage of stenosis, training in forensic pathology does not guarantee significantly improved accuracy compared with medical students. Our study showed no consistent statistically significant difference between estimates given by forensic pathologists and by medical students.     

开发老年劳动力市场的必要性与路径研究

在平均预期寿命增加和低生育率的双重作用下,中国快速进入老龄化社会,给劳动力市场和经济持续发展带来了诸多挑战。中国老年劳动力市场具有巨大的潜力,充分利用51-64岁年龄人口将会有效增加我国劳动力供给,实现二次人口红利。在分析当前中国老年劳动力市场潜力及充分借鉴国外经验的基础上,提出了推行延迟退休政策、鼓励老年人灵活就业、加强老年劳动力培训和完善社会服务体系等开发老年劳动力市场的路径。     

银发浪潮下的中国老年人力资源开发

人口老龄化是中国当前及今后很长时期都必须面临的重要问题,充分认识到老年人力资源开发的重要意义,挖掘老年人口红利将成为经济社会发展的新动力。中国拥有规模庞大的老年人力资源,但老年人口实际就业率并不高。影响老年人力资源开发和利用的因素既有社会观念、强制的退休年龄制度等宏观因素,也有老年人的就业意愿、健康状况、受教育程度等微观因素。促进老年人就业,实现老有所为是中国积极应对人口老龄化的重要举措。研究提出如下政策建议:转变社会观念,营造老年人力资源价值观念;重点开发低龄健康老年人力资源;加强对老年人的教育和培训;重视对老年就业的法律保护;改革现有的强制退休年龄制度,实行弹性退休制度。     

The global securitisation of youth

This article looks critically at the new global youth, peace and security agenda, that has been marked by the passage of United Nations Security Council Resolution 2250 in December 2015. It argues that this agenda needs to be situated within the broader context of the securitisation of development, and that the increasing interest in youth as a security subject and actor is shaped by three overlapping sets of global security concerns: the concept of the youth bulge is a euphemism for the problem of growing surplus populations worldwide; the ideal of youth as peacebuilders is a model for eliciting youth support for the current global social and economic order; and the spectre of globally networked youth being radicalised by extremist groups has legitimated joint state and private sector projects that are taking an increasingly active role intervening in the online lives of young people around the world. The article draws on an analysis of a collection of core documents that form the heart of the global youth and security agenda; and it argues for the need for greater critical reflexivity in considering the growing attention being paid to youth as a social category in global development and policy discourse.     

Public health as an agent of internal colonialism in interwar Czechoslovakia: shaping the discourse about the nation’s children

Shmidt’s text discusses the specifics of internal colonialism in the discourses and practices of the dominant group (Czechs) concerning Slovaks and Rusyns, ethnic groups from the peripheral, eastern areas of interwar Czechoslovakia. By targeting the reproductive patterns of these groups, seen as undesirable by the authorities, internal colonialism shaped the discourse about children by consistently opposing the normalized childhood inside the nation to the supposedly abnormal child development outside the civilizing process. Shmidt focuses on three interwar projects aimed at introducing new public health practices as an ‘infrastructure of dependence’ with regard to the peripheral groups. Being directly supported by the Rockefeller Foundation, these projects contributed to building the new Czechoslovak nation and securing its international legitimacy.
