“一带一路”沿线国家互联网基础设施的贸易效应——基于贸易成本和全要素生产率的中介效应分析

在"一带一路"建设背景下，研究阐释"一带一路"沿线国家互联网基础设施的贸易效应及其作用机制，对于当前中国优化沿线国家的互联网基础设施建设布局，有效激发贸易效应，应对外贸环境的不利冲击，具有重要的现实意义。文章基于贸易成本和全要素生产率的分析视角，构建2007-2017年中国与45个"一带一路"沿线国家的面板数据，运用中介效应模型实证考察"一带一路"沿线国家互联网基础设施的贸易效应。总体检验结果表明，"一带一路"沿线国家互联网基础设施有利于中国与沿线国家的双边贸易往来，且主要通过降低贸易成本而非提高全要素生产率来发挥贸易效应。异质性检验结果表明，无论区分贸易方向还是沿线国家经济发展差异，互联网基础设施都具有明显的贸易效应，其中：贸易成本的中介效应主要发生在沿线发达国家对中国进、出口贸易中；全要素生产率的中介效应主要发生在沿线国家对中国出口贸易以及沿线发展中国家对中国进出口贸易中。新形势下中国参与"一带一路"沿线国家的互联网基础设施建设，要注意合理布局和把握建设力度，既培育贸易增长新动能，也优化进出口贸易结构。     

基于关键词分析我国图书馆焦虑研究态势

国内关于图书馆焦虑的研究已经开展多年，并取得一定的研究成果。以我国图书馆焦虑的研究文献的关键词为统计对象，基于共词分析，利用聚类方法和战略坐标图分析我国在该领域的研究现状。结果表明，目前该领域的研究集中于读者自身、图书馆环境和图书馆员三大因素的研究，从理论上研究图书馆焦虑起因的关注度在降低，图书馆焦虑缓解措施的可行性和有效性研究比较缺乏。最后给出了该领域在下一步研究中的可能方向，供研究人员参考。     

高职学生网上评教数据的修正与优化处理研究

针对高职学生网上评教存在的问题,采用评教验证机制设置不合理评教的限制。对学生评教数据先剔除异常值,再分别对不同班级、不同课程和不同院系之间的学生评教数据进行修正与优化处理,得出最终的修正分值,降低了因班级、课程和院系的不同而导致的评教数据的差异性,使学生的网上评教能更准确有效的反应出教师的教学水平。     

When standardization becomes the lens of professional practice in child welfare services

This paper examines the relationship between professional work and standardization. There has been an increase in the use of standardized programmes in child welfare services (CWS) in Western society. Some researchers have criticized standardized programmes suggesting that they undermine professionals expertise and threaten their position, whereas others argue that such programmes strengthen professional practice. In this paper, we examine how standardized tools, in this case, a standardized parenting programme and a standardized Norwegian assessment tool, influence professional roles as experienced by child welfare workers (CWS professionals) in Norway. Semistructured individual and group interviews were conducted with 31 frontline workers in two CWS agencies. Our findings suggest that standardized tools increase the social workers experienced professional competence but challenge their professional knowledge base, reflective practice, and professional accountability. Professional and practical implications for CWS work are discussed in the light of these findings.     

日语“空间性状”的时间映射制约研究

日语空间性状的时间映射具有局部映射性和选择性，映射具有负向语义选择偏好；形成“水平线性空间>垂直线性空间>立体三维空间”维度制约等级。上述制约特质是时空隐喻概念相似性与语言类型特质共同驱动促成的。概念相似性是其内在驱动力，相似者易于映射，反之则受制约性强；日语的时间性特质是其负向语义选择偏好的外在驱动力。     

Radical alternative conceptualizations of the classical welfare state? Contrasting the United Kingdom and the Netherlands with Norway

In many countries, new, broad, and normative “conceptions of society” gained prominence that represent fundamentally different discursive alternatives to the classical welfare state. We present two political projects that contain radical alternative conceptualizations of the classical welfare state, the “Big Society” in Britain and the “Participation Society” in the Netherlands, and contrast these with Norwegian developments, where no such a radical alternative conceptualization of the welfare state can be found. We show that the British and Dutch political projects were attempts to replace the welfare state, whereas there is no comparable big idea about a radical overhaul of the welfare state in Norway. Our analysis contributes to a better understanding of a fundamental shift in welfare state reform, namely a radical reconsidering of the ideational and normative foundation that defines and underpins what the welfare state is or should be.     

莫言小说《丰乳肥臀》中的3D细节描写

3D细节描写是一种立体的3D视角，能将平面的画面直观地显现成3维的立体画面。《丰乳肥臀》中有大量的细节描写，有一部分是明显的3D描写，让读者融入情景、直观感受。尽管莫言不是有意识进行3D描写，但有意识地立体地细节描写写出了3D效果。     

增进学生身心健康是我国学校体育发展的根本和方向——学习贯彻习近平总书记在全国教育大会上的重要讲话精神

2018年9月10日，习近平总书记在全国教育大会上强调：“要树立健康第一的教育理念，开齐开足体育课，帮助学生在体育锻炼中享受乐趣、增强体质、健全人格、锤炼意志。”这为我国未来学校体育的发展指明了方向。学校体育要认真贯彻落实习近平总书记的重要讲话精神，把增进学生的身心健康作为学校体育工作的出发点和落脚点，切实提高学生的身心健康水平，促进学生全面发展。本文首先阐述了习近平总书记重要讲话精神的核心要义，以及所体现的以人为本的思想、高度重视把学生的健康放在首位、非常关注学生的身心协调发展等。其次，就如何落实习近平总书记的重要讲话精神提出了建设性意见：必须开齐开足体育课，保证校内外锻炼时间；提高体育课和课外体育活动的教育教学质量，加强学生的运动效果；“五育”并重，将学校体育纳入学校教育质量评价的重要组成部分；体育教师应树立强烈的社会责任感和使命感等措施和建议。     

中国省际人口流动与 人力资本流动差异性分析

人力资本流动与人口流动相关却不相同,本文采用2010-2016年全国流动人口动态监测数据,从流动方向和流动强度两方面对我国省际人口流动引致的人力资本流动现象加以研究。结果表明从流动方向分析,各省人口净流动方向基本呈现时间一致性并且流入流出区域具有稳定性。在调查期间人口净流出省份为16个,人口净流入省份为15个,没有明显变化。人力资本净流向与人口净流向完全一致,但省际人口净流向与高级人力资本净流向并不完全一致,山西、广西、重庆等省市的高级人力资本净流向始终与总人力资本净流向相反。本文采用流出流入比率和迁移选择中心两种指标测算人力资本流动强度,结果基本一致。人力资本流动中心与人口流动中心分布均较为固定。2010年人力资本流动强度最大的省份在2016年的流动强度也更强,流动强度在省际呈现惯性和马太效应。人力资本流入最强地区包括北京、天津、上海三个直辖市,人力资本流出最强省份始终包括安徽、四川、河南等省份。以人力资本流出弹性衡量人力资本流出强度与人口流出强度的相对强弱,东部地区、东北地区省份人力资本的流出强度始终大于人口流出强度,西部地区省份差异较大。考虑各省近五年经济增长状况,人口流动或者人力资本流动对经济增长的影响是非线性的。     

Female labor force participation in the US: How is immigration shaping recent trends?

Women entered the paid workforce in unprecedented numbers during the 20th century. Yet recent years have been witness to a creeping reversal in women's labor force participation. Why did the revolution stall? In response to debates over a “natural” limit to women's employment, or a cultural backlash against the dual-breadwinner household, we consider an alternative explanation, namely whether immigration has slowed the growth in female labor force participation. Using CPS data from 1998 to 2018, we show that the increase in the share of immigrants and children of immigrants in the population has reduced overall female labor force participation. However, immigration accounts for relatively little of the retreat from the labor force. Instead, the compositional effect of population change is overshadowed by behavioral shifts that affect both natives and immigrants. Lower participation rates among native-born women accounts for most of the overall decline. Despite persistent differences, we also find substantial convergence in the labor force behavior of native-born and foreign-born women, which bodes well for the long-term economic incorporation of immigrants and their children.
