广义ATO下基于多种团购模型的供应链协调

针对由多个供应商、单个制造商和零售商所组成的广义按订单装配式供应链，在上游多个供应商不确定的零部件（或商品）供应以及下游客户不确定的需求的环境下，首先分析基本模型中团购前后的零售商和制造商的利润变化，然后提出了团购的标准模型和协调模型，并比较三种不同的团购模型对各成员以及全局供应链绩效的影响。通过数学推导证明和仿真数据算例分析，结果表明：零售商自发的团购基本模型总是对制造商有利，而对零售商的好处是有限的；由制造商主导的团购标准模型在满足一定条件时是优于团购基本模型的，但有使得零售商甚至制造商自身受到损失的可能；而集中决策下的团购协调模型能够提升全局供应链的期望利润，实现渠道的帕累托改善，但协调的效果会受到团购客户组成结构的限制。     

Linking family engagement with a rights perspective: macro factors influencing practice

While child welfare practitioners in many countries are struggling to develop methods of effective family engagement, they operate within different national and cultural contexts that influence, both positively and negatively, the ability to engage with families. Increasingly, international comparisons are necessary to further understanding of the development of social work practice. This is particularly necessary because most countries utilize international frameworks (such as the United National Convention on the Rights of the Child) to provide guidance in the development of policies, programs, and interventions. Each country (and locality) struggles to advance practice to be more effective and humane. Our paper offers a comparative analysis focused on family-oriented and rights-based frameworks of different countries. Based on a review of current national policies and a review of the literature regarding family-based practices, we examine similarities and differences among four countries: the United Kingdom, Sweden, the United States, and South Korea. These countries were selected because they have some similarities (advanced industrialized democracies, professional social work, and formal child protection systems) but have some differences in their social welfare systems (policies, specific practices, and socio-cultural context). These differences can be utilized to advance understanding regarding the promise and potential for family engagement strategies. We then discuss the utility of this comparison for theory-building in the arena of child-care practice and conclude by identifying the challenges and limitations of this work.     

一种改进型专家模糊核聚类赋权方法研究

针对传统基于判断矩阵的专家模糊核聚类赋权方法，由于归一化条件的制约，导致离群点对聚类结果产生不良影响的问题，提出一种改进型模糊核聚类算法。该方法在聚类过程中，通过放宽归一化约束条件，削弱离群点对聚类结果的影响；并且针对传统基于信息熵与一致性系数线性耦合的聚类标准的局限性，提出一种基于偏差熵的赋权方法，依据专家对自身类别的聚类贡献度，确定专家权重，克服了传统方法的不足。算例表明，该方法可行、有效。     

基于交叉效率DEA与群体共识的区间乘性语言偏好关系群决策

针对区间乘性语言偏好关系群决策问题，提出了一种基于交叉效率DEA和群体共识的群决策方法。首先，提出乘性语言偏好关系导出函数的定义，并构建产出导向的DEA模型，证明了一致性乘性语言偏好关系的DEA效率得分与排序向量之间存在比例关系。在此基础上，建立基于理想值的交叉效率DEA模型，提出乘性语言偏好关系的通用排序方法。同时，基于群体共识建立目标规划模型来计算各语言偏好关系的权重系数。最后，利用Monte Carlo随机模拟的方法对群体语言偏好空间进行统计分析，得到群决策期望排序向量及其可信度。算例分析表明本文方法能够有效的避免信息损失，具有较强的适用性和较高的可信度。     

The healthy immigrant (migrant) effect: In search of a better native-born comparison group

This paper evaluates whether immigrants’ initial health advantage over their U.S.-born counterparts results primarily from characteristics correlated with their birth countries (e.g., immigrant culture) or from selective migration (e.g., unobserved characteristics such as motivation and ambition) by comparing recent immigrants’ health to that of recent U.S.-born interstate migrants (“U.S.-born movers”). Using data from the 1999–2013 waves of the March Current Population Survey, I find that, relative to U.S.-born adults (collectively), recent immigrants have a 6.1 percentage point lower probability of reporting their health as fair or poor. Changing the reference group to U.S.-born movers, however, reduces the recent immigrant health advantage by 28%. Similar reductions in the immigrant health advantage occurs in models estimated separately by either race/ethnicity or education level. Models that examine health differences between recent immigrants and U.S.-born movers who both moved for a new job—a primary motivation behind moving for both immigrants and the U.S.-born—show that such immigrants have only a 1.9 percentage point lower probability of reporting their health as fair or poor. Together, the findings suggest that changing the reference group from U.S.-born adults collectively to U.S.-born movers reduces the identified immigrant health advantage, indicating that selective migration plays a significant role in explaining the initial health advantage of immigrants in the United States.     

Adherence to three different strategies to prevent early onset GBS infection in newborns

ProblemDespite the introduction of preventive guidelines, no decrease in the incidence of early onset infection was observed.BackgroundEarly onset group B streptococcal (EOGBS) infection is an important cause of neonatal morbidity and mortality.AimOur study was conducted to determine adherence to three guideline-based group B streptococcus (GBS) preventive strategies.MethodsA prospective experimental study clustered by obstetric collaboration region was performed between March 2013 and August 2014 among midwives, obstetricians and paediatricians in the Netherlands. At baseline, the three regions operated according to the Dutch preventive strategy (founded on the risk-based strategy) in order to prevent EOGBS infection, whereas in the study period they followed either the risk-based, the combination or the Dutch strategy. Adherence was measured prospectively per pregnant woman, using predefined core elements of each preventive strategy: identification of risk factors, maternal GBS screening, application of intrapartum antibiotic prophylaxis and observation of the child. Data about adherence to the core elements were collected from medical records, maternal questionnaires and laboratory test results.FindingsIn the three regions, a total of 121 care providers and 1562 women participated.We found an overall adherence of 90% to the risk-based strategy, 57% to the combination strategy and 89% to the Dutch strategy. Adherence to a strategy in case women had EOGBS risk factors was below 20% in all strategies.DiscussionThe majority of women with EOGBS risk factors did not receive the care prescribed by any of three preventive strategies and were not treated optimally.ConclusionThe risk-based and the Dutch strategy are the recommended strategies for implementation.     

康定市吉居藏语所属问题

本文针对分布在四川甘孜州康定市吉居乡的藏族语言进行分析。吉居话的语言所属在以往研究里没有共识，有属于扎巴语的意见和属于康巴藏语的意见。通过与藏文的对比，可见该语言为一个属于康巴藏语崩波岗方言群的土话，并非木雅语或扎巴语。基于与吉居话周边土话的比较，我们提出吉居话属于崩波岗方言群雅砻江组的假设性结论。本文的分析方法亦能作为识别康巴藏语中方言所属的参考。     

关于高校中层副职干部几个基本问题的思考

高校中层副职干部具有高校干部、中层干部和副职干部的群体特征，应当具备相应的政治、思想、道德、业务、能力和身体等方面的基本素质。高校应当按照现行干部配置规制，结合内部管理体制和工作机制任用干部。高校中层副职干部的日常活动涉及到社会、学校、家庭等多个层面，必须妥善处理好各种人事关系。     

认知问题和群知识浅析

研究群知识的形式模型有助于澄清抽象的哲学概念以及概念之间的关系。然而，目前群知识的形式化的处理方法和哲学所讨论的群知识是相脱离的。对群知识的形式化的定义可称为集体知识，是关于公共问题的分布知识以及公共知识和全分布知识之间的桥梁。所有的知识都是基于对主体的不同概念的区分而获得的。为了对认知群和集体知识进行模型，需要引入新的克里普模型，即认知群模型。定义一个好的群知识有助于对基于群知识的更高层次的哲学讨论。
