Role analysis using the ego-ERGM: A look at environmental interest group coalitions

Interest groups coordinate to achieve political goals. However, these groups are heterogeneous, and the division of labor within these coalitions varies. We explore the presence of distinct roles in coalitions of environmental interest groups, and analyse which factors predict if an organization takes on a particular role. To model these latent dynamics, we introduce the ego-ERGM. We find that a group's budget, member size, staff size, and degree centrality are influential in distinguishing between three role assignments. These results provide insight into the roles adopted in carrying out coalition tasks. This approach shows promise for understanding a host of networks.     

Connecting the dots: implementing and evaluating a network intervention to foster scientific collaboration and productivity

This article presents the design and implementation of a network intervention to foster scientific collaboration at a research university, and describes an experimental framework for rigorous evaluation of the intervention’s impact. Based on social network analysis of publication and grant data, an innovative type of research funding program was developed as a form of alteration of the university’s collaboration network. The intervention consisted in identifying research communities in the network and creating a new collaborative relation between pairs of unconnected researchers in selected communities. The new collaboration was created to maximally increase the overall cohesion of the target research community. In order to evaluate the impact of the program, we designed a randomized experiment with treatment and control communities based on the Rubin Causal Model approach. The paper describes the intervention design, reports findings from the program implementation, and discusses the statistical framework for future evaluation of the intervention.

A Test of the Principle of Optimality

This paper reports on an experimental test of the Principle of Optimality in dynamic decision problems. This Principle, which states that the decision-maker should always choose the optimal decision at each stage of the decision problem, conditional on behaving optimally thereafter, underlies many theories of optimal dynamic decision making, but is normally difficult to test empirically without knowledge of the decision-maker's preference function. In the experiment reported here we use a new experimental procedure to get round this difficulty, which also enables us to shed some light on the decision process that the decision-maker is using if he or she is not using the Principle of Optimality - which appears to be the case in our experiments.

鉴于模型推理的入侵检测方法,需要在庞大的审计记录空间中搜索巨量的攻击脚本子集中的最优值,对于这一NP类完全问题,提出了应用模拟退火算法。并建立了攻击检测的优化问题模型,给出了攻击检测实验中的解空间、目标函数、新解的产生和接受准则,得到了一个合理的冷却进度表,并对实验中的模拟退火算法进行了并行化研究。实验证明,与传统的贪心算法相比,应用模拟退火算法提高了进化速度和全局寻优能力,较好地解决了搜索效率问题。     

《太原理工大学学报》(社科版)各学科来稿学术不端检测结果分析

利用社科期刊学术不端文献检测系统(SMLC)对《太原理工大学学报》(社科版)509篇自由来稿进行查重,发现各学科来稿学术不端行为的差异较大,这主要与作者和稿源有密切的关系,指出了SMLC作用的局限性,提出编辑应客观对待检测结果,结合自己的专业素养,有针对性地对各学科的来稿进行排查,把好期刊质量关。     

“技术侦查”法律解释若干问题评析--以法律解释学为视角

新《刑事诉讼法》在“侦查”一章中增加了“技术侦查措施”一节,将一直处于秘密隐晦状态的“技术侦查”措施法制化,体现了保障人权与控制犯罪的平衡。然而法典相关规定过于抽象、概括,亦存在立法疏漏。为使立法得以贯彻实行,法律解释发挥着不可替代的作用。但是,从实然层面分析,有关“技术侦查措施”之法律解释条文问题丛生,就适用案件范围、批准条件与程序、种类等问题的解释要么照搬法律条文,要么逾越立法自行创设制度。通过对“技术侦查措施”之法律解释条文进行批判性分析,以点带面,揭示整个刑事诉讼法揭示存在的问题并进行反思。
