从疫情防控看铸牢中华民族共同体意识

中华民族共同体意识是各族人民在长期生活中形成的,是全国人民团结一心的精神纽带。面对新冠肺炎疫情,铸牢中华民族共同体意识有利于巩固疫情防控的主体地位、奠定认同基础、提供集体依托等。疫情之下挑战重重,要明晰疫情应对中的制度优势,坚持从党的统一领导、全民参与、舆论引导和践行人类命运共同体理念等方面铸牢中华民族共同体意识,不断巩固疫情防控中的“巍峨长城”,坚决打赢这场疫情防控“战疫”。     

Custom Epoch Estimation for Surveys

The paper provides a method for generating epoch estimates for time series survey data, allowing for different periods of time (or even point estimates) according to user demand. The method uses a modified kriging estimator, which suppresses the contribution of sampling error variability in order to guarantee that custom epoch estimates have an interpolation property. For the veteran population variable of the American Community Survey, we utilize a simple Brownian Motion model of the population process and derive the modified kriging estimator for this case. The tuning parameters of this population model can be calibrated to the data via simple formulas. We illustrate the application of this method to the generation of point estimates of veteran population, an important objective for Veterans Affairs.     

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.

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...

企业慈善捐赠的前因变量与组织绩效研究

全球经济一体化的加速推进,使传统的生产要素对企业绩效的增强作用显现出了越来越多的局限性,企业必须寻找新的经济增长点和发展战略。在此过程中,作为承担社会责任的一种有效方式,企业慈善捐赠行为的产生与发展具有典型意义。文章运用回归分析等方法,对2008年上海证券交易所有过慈善捐赠的428家上市公司的数据资料进行统计分析与检验,结果表明:企业规模、资产负债率和企业高管人员平均受教育程度均对企业慈善捐赠有影响,但影响程度存在差异;企业通过参与慈善捐赠将获得的无形资源转化为自身的核心优势,促进组织绩效的提升;最后,提出建立有效的政策对鼓励企业参与捐赠的积极意义。     

Building relational capital: The contribution of episodic and relational community engagement

In this study, we provide evidence of the theorized connection between community engagement and the development of social capital, and the perceived value or worth of relationships among organizations and stakeholders. Using thematic analysis to understand the policy and practice frameworks of community engagement in Australian local government organizations, our analyses reveal two different types of community engagement—relational and episodic—each of which has the potential to contribute to relational dimension of social capital. The study introduces and develops new thinking around the ideas of episodic and relational engagement within the context of community engagement, and their respective contributions to the development of relational capital. Recognizing and identifying episodic and relational community engagement as separate phenomena allows researchers and practitioners to understand the theoretical dimensions of community engagement as a framework for practice.
