Cytometry inference through adaptive atomic deconvolution

In this paper, we consider a statistical estimation problem known as atomic deconvolution. Introduced in reliability, this model has a direct application when considering biological data produced by flow cytometers. From a statistical point of view, we aim at inferring the percentage of cells expressing the selected molecule and the probability distribution function associated with its fluorescence emission. We propose here an adaptive estimation procedure based on a previous deconvolution procedure introduced by Es, Gugushvili, and Spreij [(2008), ‘Deconvolution for an atomic distribution’, Electronic Journal of Statistics, 2, 265–297] and Gugushvili, Es, and Spreij [(2011), ‘Deconvolution for an atomic distribution: rates of convergence’, Journal of Nonparametric Statistics, 23, 1003–1029]. For both estimating the mixing parameter and the mixing density automatically, we use the Lepskii method based on the optimal choice of a bandwidth using a bias-variance decomposition. We then derive some convergence rates that are shown to be minimax optimal (up to some log terms) in Sobolev classes. Finally, we apply our algorithm on the simulated and real biological data.     

关于我国临终关怀事业的伦理思考

随着临终关怀事业的产生和不断发展，不得不承认这推动了人类社会的文明和进步。随着人类社会的不断进步，人们越来越重视坚持医学人道主义，这使人们意识到了发展临终关怀事业的重要性。由于大多数中国人受几千年流传下来的传统文化的影响，形成了固有的伦理观念，那么，我们从伦理学的角度出发，去思考一些有关于临终关怀的问题，必将有利于临终关怀事业的发展。     

Justice Sensitivity in Childhood and Adolescence

Individuals differ in their sensitivity toward injustice. Justice‐sensitive persons perceive injustice more frequently and show stronger responses to it. Justice sensitivity has been studied predominantly in adults; little is known about its development in childhood and adolescence and its connection to prosocial behavior and emotional and behavioral problems. This study evaluates a version of the justice sensitivity inventory for children and adolescents (JSI‐CA5) in 1472 9‐ to 17‐year olds. Items and scales showed good psychometric properties and correlations with prosocial behavior and conduct problems similar to findings in adults, supporting the reliability and validity of the scale. We found individual differences in justice sensitivity as a function of age and gender. Furthermore, justice sensitivity predicted emotional and behavioral problems in children and adolescents over a 1‐ to 2‐year period. Justice sensitivity perspectives can therefore be considered as risk and/or protective factors for mental health in childhood and adolescence.     

网红直播带货的伦理审视

随着网络直播的兴起和网红经济的发展,"网红直播带货"成为一种新的重要营销方式,它不仅能满足人们个性化的物质需求,而且能满足个体的社交化情感诉求,但其中所潜藏的诚信缺失和个体消费成瘾等伦理失范问题较为突出。加强个人义利观教育、完善社会诚信监督机制,丰盈个体精神生活、净化社会消费风气,则是解决这些伦理问题的可行性路径。     

3-6岁学前儿童情绪与行为问题的调查与分析——以惠州市为例

摘 要：应用儿童长处与困难（SDQ）问卷（父母版），采用分层随机抽样方法，对惠州市1528名3-6岁儿童的情绪与行为问题进行调查。研究发现：惠州市3-6岁儿童情绪与行为问题异常情况比较严峻，儿童心理健康状况值得重视；不同地域、年龄学前儿童存在不同的情绪与行为问题，需要分类干预。其中农村儿童的情绪与行为问题异常情况尤为严重，需要得到广泛的关注和解决。     

Resolving complex community problems: Applying collective leadership and Kotter's change model to wicked problems within social system networks

How does collective leadership within social networks resolve chronic and complex problems common to communities? Unfortunately, sometimes it does not, but when it does, the outcome may be truly extraordinary. We use a case study approach to explain how one Midwest community within the USA applied collective leadership within a community network to reduce teen births. It took ten years of what many identified as provocative media campaigns and comprehensive sex education programs to reduce teen births by 65%, significantly exceeding the stated goal. Using Kotter's change model as a backdrop, powerful strategies and provocative creativity reveal courageous leadership within a social network of diverse people and organizations focused on improving the social well being of their community.     

Parenting Style,Child Emotion Regulation and Behavioral Problems: The Moderating Role of Cultural Values in Australia and Indonesia

Abstract

Research has shown that the congruence of parenting styles with cultural values, rather than parenting styles alone, impacts child adjustment. This study examined if parents’ cultural values moderate the relationships between parenting styles and child outcomes across both an individualist culture (Australia) and a collectivist culture (Indonesia). Three hundred and eighty-seven parents of 2–10-year-old children from both countries reported their parenting styles, the importance of the collectivistic values (security, conformity, and tradition), and their child's emotion regulation and behavioral problems. In both countries, authoritative parenting was associated with higher child emotion regulation and lower levels of behavioral problems, and authoritarian parenting was associated with lower child emotion regulation and higher levels of behavioral problems. Although cultural values did not moderate the relationship between authoritarian parenting and child adjustment, in both countries greater importance placed on tradition attenuated the positive effect of authoritative parenting on child outcomes.     

Maternal responses to negative emotions and child externalizing behavior: Different relations for 5‐, 6‐, and 7‐year‐olds

Emotional and behavioral maturity expectations increase as children transition to primary school; thus, maternal responses that support and encourage children's expression of negative emotion may not benefit school‐age children as much as preschoolers. The current study explored a change in the utility of these maternal responses among 187 families (62 5‐year‐olds, 75 6‐year‐olds, and 50 7‐year‐olds). Mothers reported on their responses to children's negative emotions and children's externalizing and internalizing behaviors at two time points over 1 year. Multiple group analysis within cross‐lagged path models revealed a positive association between non‐supportive maternal responses and later child externalizing behaviors among 5‐year‐olds. However, non‐supportive responses were related to decreases in externalizing behaviors among the 7‐year‐olds. Discrepant findings between the 5‐ and 7‐year‐olds may represent a developmental shift in the function of mothers' emotion socialization practices.     

长征时期我党关于民族问题探索的历史演变与现实启示

中国工农红军长征时期，党高度重视民族问题，制定和实施了一系列符合中国革命和民族实际的民族纲领政策，开创了一条运用马克思主义民族理论解决中国民族问题的探索之路。中国共产党早期的民族纲领与民族政策主张是从马克思列宁主义关于民族独立、民族分离、建立联邦或区域自治等方面去阐释。随着我国革命形势的发展变化，党已认识到民族独立或联邦制并不符合中国的国情，不主张民族自决和实行联邦制，并最终确认了在统一的国家中实行民族区域自治的政策。认真分析长征时期党民族理论政策的发展演变进程，对新时期科学总结党民族工作经验和指导民族工作实践，不断发展和完善中国特色社会主义民族理论体系，实现中华民族伟大复兴具有重要意义。
