《1844年经济学哲学手稿》与《神圣家族》中的生活思想

《1844年经济学哲学手稿》和《神圣家族》都是马克思主义创始人早期思想的代表性著作，二者都把“生活”作为重要概念进行论述。从作为经济学哲学概念到作为社会批判概念，马克思主义创始人对“生活”的认识经历了从对物质生产活动的重视到对无产阶级普遍贫困生活的揭露，从分析“生产生活”的异化到对“非人性”生活的批判，从“生活的手段”到消灭“非人性的生活条件”的思想历程。人类的历史是人类生活发展的历史。解决人的美好生活如何实现的问题，在马克思恩格斯的生活思想中居于核心地位，这对当今中国具有重要的理论指导价值。中国特色社会主义进入新时代，从开启一种全新文明的生活形态的高度来理解新时代的美好生活，才能准确把握我国社会主要矛盾变化的深刻意义。     

“围城”中的“历史人”——论李梅亭与霍华德·科克形象的伦理悖论及镜鉴意义

《围城》与《历史人》都是著名校园讽刺小说.其代表人物李梅亭与霍华德·科克都是生活在动荡时期相对平静的大学校园“围城”中的高级知识分子,他们在日常生活中言与行的矛盾、表与里的抵牾,在职场生涯中道貌岸然的显性身份表象与其庸俗无聊、滑稽可笑的隐性角色扮演形成的伦理悖论,无疑具有强烈的喜剧效果和深刻的反讽性质.由于人物所处经济、政治、文化背景不同,其伦理悖论又各具特点,李梅亭身上散发出陈腐的朱熹式伪道学气息,霍华德·科克则是在激进外表下包裹着极端利己主义.李梅亭与霍华德·科克形象蕴含的伦理悖论在知识分子中具有一定典型性,其形象既为历史存照,也对今天重塑大学灵魂、重塑知识分子健全人格具有一定镜鉴意义.     

美国中小学的体验式学习及启示

体验式学习的内涵随着时代的发展而逐渐丰富和深化，但无论其如何演变，直接经验和反思始终是体验式学习这一概念的内核。体验式学习理念渗透于美国教育文化之中。具体表现在：小学阶段的教育以学生的真实感知为基础，注重为学生提供真实体验的机会和激发学生的学习兴趣；中学尤其是高中阶段的教育以学生的真实体验为基础，注重为学生提供在新情境中检验所学知识的机会，注重学生知识、技能的内化吸收。美国中小学体验式学习的实施经验可为我国基础教育课程改革提供如下启示：（1）进一步树立和推广体验式学习理念；（2）创设学生进行真实体验的教学环境；（3）注重实施基于学生体验式学习的表现性评价。     

新时代推进大中小学劳动教育的三重维度

劳动教育肩负着培养德智体美劳全面发展的社会主义建设者和接班人的重要任务,因此,新时代推进大中小学劳动教育是青少年学生全面发展的客观需要。新时代推进大中小学劳动教育需要从时代性、规律性、创造性三重维度着手,把握新时代大中小学劳动教育的时代特征,遵循新时代大中小学劳动教育的内在规律,激发新时代大中小学劳动教育的内生动力。     

工业劳动力流动、资本创造与经济地理空间均衡

资本创造模型（CC模型）忽视了要素流动对产业空间分布的影响。而发展的新的资本创造模型则认为资本集聚的过程必然伴随着工业劳动力的流动过程。另外，是资本的实际收益而不是名义收益决定资本是否创造。研究结果表明，随着贸易自由度、工业品支出份额及资本贴现率的变大，替代弹性及资本折旧率的变小，将降低对称结构的稳定性，而提高中心-外围结构的稳定性；经济地理空间的产业均衡是集聚力和分散力相互作用的结果。当企业生产工业品的规模报酬递增程度足够显著，或者工业品支出份额很高时，市场拥挤效应将彻底消失，并转化成为促进产业集聚的动力；突破点与持续点的大小比较可以形成不同的关系，这意味着随着贸易自由度的变化，本文发展的资本创造模型可以体现出多样化的产业空间动态演化行为。     

Developing and testing a mobile application for breastfeeding support: The Milky Way application

BackgroundSupporting women to continue breastfeeding is a global challenge. The Milky Way Program is an effective face to face intervention to increase breastfeeding rates up to six months postpartum. The sustainability and access to the Milky Way Program could be enhanced by transforming it into a mobile application allowing women to access relevant information from their own place at a convenient time.AimTo explore the process of transforming the Milky Way Program into an acceptable and usable mobile health application.MethodStakeholders including multidisciplinary researchers and end-users designed the application based on the Milky Way Program by using Persuasive System Design principles. A mixed-method approach was used in the development and evaluation process. Seven women were recruited through convenience sampling to pilot test the application. The women’s feedback was collected through an online survey six weeks after birth and individual interviews at four months postpartum.FindingsWomen in the pilot study reported that the breastfeeding application was well designed, easy to use, interactive, reassuring and evidence-based with credible sources of information.ConclusionThe Persuasive System Design model combined with end-user engagement can feasibly inform the development of an acceptable and usable mobile health application for breastfeeding based on a proven clinical intervention. Further rigorous testing is required to evaluate the effectiveness of the application on breastfeeding initiation and duration.     

“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。     

习近平外交思想指向下中日关系发展的新定位

近年来中日关系逐步转寒回暖,无论政治交流氛围,还是经济合作环境都得到了较大改善,这离不开中国政府根据国际形势及中日关系的变化及时调整对日政策,也充分体现了习近平新时代中国特色社会主义外交思想对中日关系缓和发展的引领作用。在安倍首相访华及习近平主席出席大阪G20峰会之后,两国政府在努力建设契合新时代要求的中日关系上达成多点共识。中日双方将依托“一带一路”倡议和第三方市场合作的平台,进一步致力于深化经济合作,维护多边主义和自由贸易体制,共同培育新动能和新的增长点,加速东北亚区域命运共同体的构建。     

The disaster relief and social work after the Wenchuan earthquake in Mainland China

ABSTRACT

This paper mainly focuses on the development of disaster social work in Mainland China and the intervention of social work in disaster relief. Before the Wenchuan earthquake and in the initial stage of post-earthquake, disaster social work was mainly based on individual psychotherapy; from the earthquake to the year of 2012 in which post-earthquake recovery and reconstruction was completed, the disaster relief began to emphasise community building and integration, while the basic framework for disaster social work was also established. Social workers begin to explore the new mode of developmental and localised disaster social work. By combining with the practical experiences from disaster social work, this paper tries to highlight the dilemmas confronting disaster relief in Mainland China and put forward some corresponding countermeasures and suggestions, which could improve the future disaster relief system in Mainland China.     

The competing risks analysis for parallel and series systems using Type-II progressive censoring

Abstract

Recently, the study of the lifetime of systems in reliability and survival analysis in the presence of several causes of failure (competing risks) has attracted attention in the literature. In this paper, series and parallel systems with exponential lifetime for each item of the system are considered. Several causes of failure independently affect lifetime distributions and observations of failure times of the systems are considered under progressive Type-II censored scheme. For series systems, the maximum likelihood estimates of parameters are computed and confidence intervals for parameters of the model are obtained using Fisher information matrix. For parallel systems, the generalized EM algorithm which uses the Newton-Raphson algorithm inside the EM algorithm is used to compute the maximum likelihood estimates of parameters. Also, the standard errors of the maximum likelihood estimates are computed by using the supplemented EM algorithm. The simulation study confirms the good performance of the introduced approach.
