高维大数据基因网络中的社区发现——以NC方法为例

从大量基因中识别出致病基因是大数据下的一个十分重要的高维统计问题。基因间网络结构的存在使得对于致病基因的识别已从单个基因识别扩展到基因模块识别。从基因网络中挖掘出基因模块就是所谓的社区发现（或节点聚类）问题。绝大多数社区发现方法仅利用网络结构信息,而忽略节点本身的信息。Newman和Clauset于2016年提出了一个将二者有机结合的基于统计推断的社区发现方法（简称为NC方法）。本文以NC方法为案例,介绍统计方法在实际基因网络中的应用和取得的成果,并从统计学角度提出了改进措施。通过对NC方法的分析可以看出对于以基因网络为代表的非结构化数据,统计思想和原理在数据分析中仍然处于核心地位。而相应的统计方法则需要针对数据的特点及关心的问题进行相应的调整和优化。     

Using theory of change as a framework for examining community context and philanthropic impact

As part of the process of examining their theory of change (TOC) and reflecting on grant making activity, one Midwestern foundation employed a multipronged strategy to assess 209 community-based mental health grants across seven years of funding. This article details the evaluation approach, which comprised these areas of the TOC: grantees’ use of evidence-based interventions, cultural competency, quality improvement, community collaboration, and use of integrated care. Inductive analyses identified grantees’ use of innovative practices, trauma-informed care, and use of validated instruments. In an iterative exercise spanning multiple years, the foundation and researchers found ways to gather information about community capacity and impact while simultaneously minimizing grantee data collection/reporting burden. Findings revealed that community agencies were improving in their uptake of evidence-based interventions and use of validated instruments. Community grantee use of trauma informed care also improved over the study period. Grantee desire to collaborate and coordinate services within the community was also strong. The research also revealed that in multiple domains (such as technology and non-profit operating costs) grantees needed support in building agency capacity. These findings shed light on which aspects of the foundation’s TOC were being addressed through funding, and which areas of the community needed additional support.     

Using a community-created multisite evaluation to promote evaluation use across a sector

Multisite evaluation has been cited as a strategy for building knowledge about a program's success and enhancing evaluation capacity and evaluation use. Even so, the extent to which data from these efforts are made available to individual project participants varies. This article describes a community-created multisite evaluation that was designed to overcome this limitation. Based on the negotiated centralized evaluation model and implemented within the context of a community of practice, the EvalFest community-created multisite evaluation has used shared measures to collect data from 30,000 participants from partner sites across the community over three years. This article describes the design characteristics of the community-created multisite approach, and presents results related to partners’ evaluation use that demonstrate the early success of this method. We conclude by considering how this strategy might be applied to other sectors.     

The impact of the European Youth Guarantee on active labour market policies: A convergence analysis

The European Union’s (EU) Youth Guarantee aims to improve the labour market situation of young people. Rather than prescribing a uniform policy model, it acknowledges that supportive measures need to align with national, regional and local circumstances. It thus seeks to promote mutual policy learning through the open method of coordination. As an innovative measure, the EU has deployed funding programmes to support the domestic measures related to the Youth Guarantee. We therefore examined in this study whether this mix of recommendations and financial incentives has entailed a convergence of member state policies. Our analysis of policy outputs for the period 2007?2014 yields a mixed empirical picture. There is catching‐up convergence regarding policies’ sectoral coverage but increasing divergence concerning the number of adopted policy instruments. The first two years of financial incentives did not produce any effect on enhancing policy experimentation among less active member states. We offer an optimistic and a pessimistic interpretation of these findings.     

制度嵌入性与地方食品系统——基于Z市三个典型社区支持农业（CSA）的案例研究

针对日益恶化的食品安全现实,部分消费者退出了部分主流食品系统,转而纷纷采用替代性的地方食品系统模式。而在地方食品系统中,社区支持农业(CSA)是其最主要的表现形式。文章对Z市三个典型的社区支持农业模式(即消费者推动型、生产者推动型以及NGO推动型)是如何再嵌入到具体的制度情境中,从而解决食品品质不确定性这一问题进行了论述。同时,对于这三大模式之间的异同也进行了简要的分析。     

民族法制的中国经验及其贡献

在中国，平等、团结、互助的社会主义民族关系已经建立并进一步巩固发展，这是实施民族区域自治制度的结果，它为当代国际社会解决民族问题提供了有益的经验。这些经验是对民族团结概念作宪法安排以建构公民认同；以少数民族干部制度作为沟通的制度性安排；自治权作为发展权的制度设置以实现各民族的共同繁荣发展；设立少数民族聚居区的独特安排，保证了民族关系历史与现实的统一；以多元与一体并存的发展形式，保证各民族语言文化的平等共同发展。     

和平对我们意味着什么？

从普世的层面来说,和平指的是人类作为一个共同体之内部的和谐相处关系状态。在比较具体的层面,可以将和平放置在中国历史、传统、文化,以及现实处境的场域中来做充分注意文化差异性的思考。和平是一种宁静的状态,是一切公共关系、秩序的最高原则。真正、持久的和平必须建立在一种珍视和平价值的文化基础上。人类必须建设一种浓郁的和平文化,使之成为比竞争文化更为基础性的自觉。世界和平是世界人民的诉求,必须由世界人民通过对话、交流、融合建设起来。和平是所有人类的根本需求,是最值得珍视的人类社会状态,保持和平,需要建设和平的文化,也需要国际秩序保障机制的改革建设。     

社区治理主体问关系:问题、成因与重构

社区治理主体间关系是一个关乎社区治理绩效的重要问题.当前我国社区治理主体间存在着权力冲突、关系混乱的状态,不利于推进社区的和谐与发展.社区治理主体间关系存在问题的直接原因在于社区治理明显的"行政化倾向",而这又根源于我国传统计划经济体制、行政管理体制以及文化观念的影响.要理顺社区治理主体间关系,需要综合平衡各种社区治理...     

铸牢陆地边境民众中华民族共同体意识初探

以中国99个陆地边境口岸为例,在边境界定、边境县人口统计基础上,分析发现,影响边境民众铸牢中华民族共同体意识的因素主要有四个方面:陆地边境区域经济社会发展滞后,边境民众对铸牢中华民族共同体意识的认识有限,跨国民族(含跨境、跨界民族)的民心相通作用发挥不足,周边国家关系深受大国渗透及干涉。铸牢中华民族共同体意识的可行性路径有"五全":一是全覆盖,即中国边境区域全覆盖;二是全小康,即持续推进边境人口全面建设小康社会;三是全方位,即全方位设计符合边境实际的铸牢中华民族共同体意识的内容;四是全辐射,即将铸牢陆地边境民众中华民族共同体意识与周边国家命运共同体意识连接起来;五是全过程,即注重铸牢中华民族共同体意识过程建设,达到文化润疆的目标。根据边境民众对铸牢中华民族共同体意识的认知程度,铸牢中华民族共同体意识的内容包括山河恋、家国情、中国心、邻国缘。     

Personal Values as Mitigating Factors in the Link Between Income and Life Satisfaction: Evidence from the European Social Survey

Using data from the first two rounds of the European Social Survey, we examine the link between income, reference income and life satisfaction across Western Europe. We find that whilst there is a strong positive relationship between income and life satisfaction, reference or comparison income exerts a strong negative influence. Interestingly, our results confirm the importance of personal values and beliefs not only as predictors of subjective well-being, but also as mitigating factors in the relationship between income, reference income and life satisfaction. While our findings provide additional empirical support for the relative utility hypothesis, they are also consistent with Rojas’ (J Econ Psychol 28:1–14, 2007) Conceptual-Referent-Theory (CRT), which is based on the premise that the salience of income and comparison income depends on one’s intrinsic values and personal beliefs.
