基于n-宗派的C2组织协作性量化分析

C2组织的协作性是目前信息化战争研究中的一个热点。利用"社会网络分析方法",对C2组织的指挥控制关系网络模型进行"n-宗派"分析,可以有效地揭示组织的子结构特征以及定量地研究组织的协作性。分析了指挥控制关系网络模型n-宗派中"n"的现实意义,设计了"宗派协作指数"和"组织协作指数"的计算方法和公式。结合示例,以2-宗派为例说明了C2组织协作性量化分析的步骤和过程。研究表明,基于n-宗派的C2组织协作性量化分析具有可操作性和现实意义。     

农村文化建设对农村社会稳定的双向效应

社会稳定是改革发展的重要前提,而保持农村稳定是全社会稳定的关键。维护农村社会稳定根本途径在于文化建设,但文化建设对农村社会稳定有双向效应。文化建设对农村社会稳定的正面效应有减贫效应、社会结构优化效应、社会控制效应、社会心理优化效应和社会化效应,而文化建设的受益不均衡效应、虚化效应、过度社会动员效应及其信息失稳效应等又不利于农村社会稳定。因此,要充分重视农村文化建设的积极作用,也要清醒认识其负面效应,并为维护农村社会稳定考虑扬正抑负的对策。     

教育阻断深度贫困地区贫困代际传递的作用分析——基于新疆八个地区的实证研究

教育既是阻断贫困代际传递的治本之策,亦是脱贫可持续发展的内生动力。本研究基于新疆八个地区的实地调研数据,运用转换矩阵分析法和对数线性回归模型呈现了贫困代际传递与教育代际流动的现状,进而分析各级教育阻断贫困代际传递的作用,结果表明,贫困结构由绝对贫困向相对贫困改善;贫困子代受教育程度低,教育向上代际流动性较弱;教育具有阻断贫困代际传递的作用,中学教育阶段最为显著。教育扶贫应精准识别扶贫对象,增强受教育意愿,促进教育代际流动;差异分配教育经费,分学段扶贫;培养与引进并举,加强师资建设。     

Equilibrium customer strategies and social–profit maximization in the single‐server constant retrial queue

We consider the single‐server constant retrial queue with a Poisson arrival process and exponential service and retrial times. This system has not waiting space, so the customers that find the server busy are forced to abandon the system, but they can leave their contact details. Hence, after a service completion, the server seeks for a customer among those that have unsuccessfully applied for service but left their contact details, at a constant retrial rate. We assume that the arriving customers that find the server busy decide whether to leave their contact details or to balk based on a natural reward‐cost structure, which incorporates their desire for service as well as their unwillingness to wait. We examine the customers' behavior, and we identify the Nash equilibrium joining strategies. We also study the corresponding social and profit maximization problems. We consider separately the observable case where the customers get informed about the number of customers waiting for service and the unobservable case where they do not receive this information. Several extensions of the model are also discussed. © 2011 Wiley Periodicals, Inc. Naval Research Logistics, 2011

IED casualties mask the real problem: it's us

Casualty figures suggest that the US/Allied Counter Improvised Explosive Device (C-IED) policy and the present allocation of national assets, resources, and intellectual capital have not been very successful. A number of explanations for why this has been the case are discussed and critiqued here.     

Crime facilitation purposes of social networking sites: A review and analysis of the ‘cyberbanging’ phenomenon

There have been growing claims in media circles and law-enforcement settings that street gangs and criminal groups are turning to Internet-based social networking sites for various reasons ranging from the showcasing of their images and exploits to the suspected recruitment of members. The present study investigates whether such a trend is, in fact, in place. The presence of street gangs on these Internet sites is referred to as cyberbanging. While there is some anecdotal evidence suggesting that gangs are turning to social networking sites, there is little available research on exactly how street gangs and criminal groups use the Internet. Our main argument is that gang culture is in many ways an individualized phenomenon and this feature ties in directly with recent assessments of the Internet as a setting that is governed by a process of networked individualism. This theoretical link between the individualized gang setting and the presence of gang members on social networking sites helps us understand why recruitment is improbable even in a context where people are openly diffusing their image and exploits to a growing number of Internet users. The empirical segment of this research adds to this general outlook. Based on a keyword search of over 50 street gang names, the three main social networking sites (Twitter, Facebook, and MySpace) were monitored for street gang presence. Results illustrate that gang presence on social networking sites is linked primarily to promoting a general gang or street culture through individual displays. In regard to the visitors to such sites, there is no evidence that they are being tricked or manipulated in any way. They are, however, showing their curiosity in regard to such groups and, for those who share their comments and opinions, signs of support are evident. Thus, whereas criminal gangs are not proactively using the Internet to convert anyone into being gang members, social networking sites are creating a new venue for people who share or are sensitive to the values underlying street gang lifestyle to come together. These sites essentially create a new convergence setting for gang members to interact with a wider number of people who would probably never have been exposed to their lifestyles and exploits through physical interactions. The study's conclusion extends these findings toward further research in this area, as well as outlining the more relevant implications for law-enforcement monitoring of this growing phenomenon.     

信息推荐系统中的朋友关系预测算法设计

伴随着互联网规模的不断扩展,信息过载问题越来越突出。信息推荐系统被视为解决信息过载问题的最有效方法。然而目前的方法大多数仅考虑用户独立的反馈,而忽略用户的社会属性对推荐的重要作用,这对信息推荐系统的性能会造成巨大的影响。为此,本文提出了基于朋友关系预测的信息推荐算法,将用户的社会关系预测引入信息推荐过程中,分别基于用户的拓扑信息及历史交互信息建立用户社会关系的存在性判定及关系类型判定,并利用线性回归分析方法和逻辑回归分析方法实现了基本特征的融合。最后,通过在Epinions和Slashdot真实数据集上的实验证明,本方法能够有效提高用户社会关系预测的准确性。     

道德教育的社会支持系统探析

在社会转型时期的学校教育受到许多挑战,加上一直以来对学校在道德教育中的作用被过分放大,使学校面临巨大的压力。实际上,真正的、有效的道德教育需要一个广泛的支持系统。我国需要结合学校、家庭、社区及社会的综合力量,营造"大德育"的环境,建立起道德教育的社会支持系统。     

消防执法程序与法律修改探讨

《中华人民共和国消防法》于2008年修订后引发消防执法程序的变化,取消了大部分消防行政处罚前责令限期改正的前置条件,加大了行政处罚力度,但由此引发了行政不作为的现象;由于法律对同一行为规定了两种处理方式,导致出现选择性执法现象;由于法律对虚假备案违法行为行政处罚规定模糊,使该行为不能得到有效处理。针对上述问题及其对消防工作带来的深刻影响,尝试对消防执法工作提出建议。
