属性集容量确定的夹挤式测度模式及其推算模型

迄今，为解决多属性偏好关联决策属性集容量判断指数复杂性难题所提出的λ模糊测度模式与k-可加模糊测度模式，以及建构在它们之上的属性集容量确定的推算模型，尚存在着适用性差的技术不足。为此，以平衡容量判断的可操作性和容量推算的准确性为视角，提出了一种新容量测度模式，即关于容量判断与推算的夹挤式测度模式，并在此基础上通过引入决策者较易判断给出的容量序信息构建了相应的容量推算模型。基于数值模拟的对比分析表明：新模式不仅在应用可行性上高于k-可加模糊测度模式，而且从容量推算的准确性上看也明显优于λ模糊测度模式和k-可加模糊测度模式，因而对实际决策具有更强的适用性。     

怀疑主义与认知价值

当代知识论越来越重视认知价值的研究，但从认知价值角度去重新思考传统怀疑主义问题的研究却很少。历史上的怀疑主义者既认为我们无法拥有任何知识，又主张我们应该悬置判断。因此，他们不仅预设了一个高的知识标准，而且预设了一个价值标准：任何达不到知识标准的认知状态都是没有认知价值的。但这个价值标准是错误的，所以我们即使无法达到怀疑主义者所设定的知识标准，也不必悬置判断。假设怀疑主义者认为我们无法拥有任何知识，同时认可“有些达不到知识标准的认知状态也有认知价值”，那么怀疑主义就没有很大的威胁性，因为即使我们无法获取知识，也可以获得具有认知价值的东西，取得认知进步。此外，摩尔主义、语境主义、溯因主义这几种对怀疑主义的主要回应是否成功，最终都依赖于对认知价值的讨论。     

《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。     

Impact of support networks for breastfeeding: A multicentre study

Background

The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.

“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.     

Elementary School-age Children's Attitudes Toward Children in Same-Sex Parent Families

As numbers of families with same-sex parents increase in the United States, children are more likely to encounter diverse family structures. Given that young children can demonstrate in-group bias, prejudicial attitudes, and social exclusion, it is important to understand how children perceive their peers in diverse families. To our knowledge, no studies have assessed elementary-school-age children's attitudes about same-sex parent families. Here, 131 elementary school students (M_age = 7.79 years; 61 girls) viewed images of same-sex (female and male) and other-sex couples with a child and then were asked about their perceptions of these families, particularly the children. Results indicated participants' preferences toward children with other-sex versus same-sex parents. Developmental and practical implications about children's attitudes toward sexual minority parent families are discussed.     

研究生培养政策70年:演变逻辑与发展走向

新中国成立70年来，我国研究生培养政策经历了初创起步、推进发展、稳步延伸和调适深化四个发展阶段。在演进逻辑上，凸显出国家需求与市场诉求的权衡性、培养目标注重个人成就与社会发展价值的双维导向、培养质量保障体系趋向质量和效益二维共进等特征。研究生培养政策是个动态发展系统。随着时代的发展和变迁，应在政策制定和发展的动力机制、政策目标的价值导向、政策执行的监督评价及保障决策等方面作出适时调整。     

Providing a secure base for LGBTQ young people in foster care: The role of foster carers

The experiences and needs of lesbian, gay, bisexual, trans and queer/questioning (LGBTQ) young people in care have been overlooked in England, in both policy and research. This paper reports on findings from the first study of LGBTQ young people in care in England and focuses on the nature of foster carers' experiences and perspectives on caring for LGBTQ young people. Qualitative interviews regarding the fostering role in caring for LGBTQ young people were conducted with a sample of foster carers (n = 26) and analysed thematically. Foster carers described the importance of offering LGBTQ young people not only the nurturing relationships that all children in care need but also availability, sensitivity and acceptance to help young people manage stigma and other challenges associated with minority sexual orientation and gender identity. The Secure Base caregiving model provided a framework for analysing the different dimensions of these relationships. Understanding caregiving roles and relationships for LGBTQ young people in care has important implications for recruiting, training, matching and supporting foster carers to care for LGBTQ young people effectively.     

Creating a positive emotional culture: Effect of internal communication and impact on employee supportive behaviors

The study surveyed 506 employees in the United States to test the effect of internal communication (i.e., corporate-level symmetrical and leadership-level responsive communications) on fostering a positive emotional culture characterized by companionate love, joy, pride, and gratitude. In addition, we tested the interplay between corporate internal communication and a positive emotional culture and its influence on supportive employee behaviors, specifically, organizational citizenship behavior (OCB) and employee advocacy. Results indicated that symmetrical communication and responsive leadership communication cultivated a positive emotional culture in organizations. Such culture also fostered employee OCB and advocacy. Moreover, corporate symmetrical communication directly and positively influenced employee OCB. Finally, this study found that employee OCB positively affected employee advocacy. The theoretical and practical implications of the findings for public relations scholars and practitioners were discussed.     

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。
