基于局部社团结构平衡的双模符号网络链路预测研究

随着互联网产业的高速发展,双模符号网络已经成为一类常见的复杂网络,然而针对此 类网络的分析较少。本文在传统非符号网络局部社团理论和符号网络结构平衡理论的基础上,首次提出了双模符号网络下的局部社团理论。这一理论不仅考虑了符号网络中共同邻居的信息,还引入了共同邻居间存在的连接。进一步地,本文推导出符号网络中基于局部社团信息的加权平衡回路增益指数,该指标可以表示双模符号网络中用户节点和产品节点间的符号关系。为了将该指标更好地应用于双模 符号网络链路预测问题,本文提出了加权平衡回路增益分类器算法。实验结果表明,相比其他经典链路预测算法,新算法具有更好的预测能力。     

邓小平凝聚改革共识思想解析

邓小平凝聚改革共识思想，是邓小平理论的重要内容。邓小平认为认清改革的社会主义性质、选定恰当的改革内容和方式、增强改革的动力，都需要凝聚改革共识。对于如何凝聚改革共识，邓小平认为必须坚持解放思想，拿事实来说话，要勇于试验积累经验，要加强宣传教育，要同人民商量办事。邓小平的凝聚改革共识思想，对今天推进全面深化改革的实践具有重大的意义。     

理论与实践:译者的纯语言——以许渊冲《唐诗三百首》为例

许渊冲对诗歌的贡献不仅在于翻译理论,也在于他的翻译实践。根据本雅明对翻译中纯语言的论述,即上帝的语言是纯粹的,人类的语言因带有偏见,是不纯粹的为依据,再次探索翻译理论与翻译实践的关系,以许渊冲唐诗三百首中《送孟浩然之广陵》译文为例,肯定许渊冲的翻译硕果,同时兼顾翻译理论发展与翻译实践的译者的影响力。

浅析社会工作的结构化过程

本文旨在分析社会工作的运行机制,试图溯源社会工作广泛的主客体关系,借助吉登斯的结构化理论,反思社会工作领域内的多重解释和二元对立,并将社会工作的运行机制归结到结构化的构成之中,在密布资源和规则的结构之中发现充满"实践意识"的行动者,从而感应社会工作发展的脉动。     

How and why are Theory of Change and Realist Evaluation used in food security contexts? A scoping review

The complex ways in which food security actions lead to nutrition and other health outcomes make it important to clarify what programs work and how, with theory-driven evaluation emerging as a promising approach to evaluate complex programs. However, it is unclear how and why theory-driven evaluation is applied in food security contexts. Our objective is to examine the development and use of Theory of Change and Realist Evaluation to support food security programs globally. Using a systematic search and screening process, we included studies that described a food security program, used a Theory of Change or Realist Evaluation, and presented original research or evaluations. We found a total of 59 relevant Theory of Change studies and eight Realist Evaluation studies. Based on our analysis, Theories of Change arose in response to three main problems: 1) the need to evaluate under complexity; 2) challenges with evaluation; and, 3) information gaps surrounding a program. In contrast, Realist Evaluation was reported to be developed primarily to understand a program’s outcomes. Reflecting on the problem to be addressed in the evaluation would help improve understandings of the evaluation context, which would then inform the choice and design of an evaluation approach.

Assumptions,conjectures, and other miracles: The application of evaluative thinking to theory of change models in community development

Unexamined and unjustified assumptions are the Achilles’ heel of development programs. In this paper, we describe an evaluation capacity building (ECB) approach designed to help community development practitioners work more effectively with assumptions through the intentional infusion of evaluative thinking (ET) into the program planning, monitoring, and evaluation process. We focus specifically on one component of our ET promotion approach involving the creation and analysis of theory of change (ToC) models. We describe our recent efforts to pilot this ET ECB approach with Catholic Relief Services (CRS) in Ethiopia and Zambia. The use of ToC models, plus the addition of ET, is a way to encourage individual and organizational learning and adaptive management that supports more reflective and responsive programming.
