新时期公安边防部队涉警舆情应对研究

随着现代信息技术的发展以及互联网的普及,社会舆论载体日益增多,而公安工作的特殊性又使公安机关极易成为社会关注的焦点。广泛、动态的涉警舆论一方面促进了公安边防工作的有效开展,但另一方面也给公安边防部队及公安边防工作带来巨大挑战。密切掌握涉警舆情动态,切实提高公安边防部队应对负面涉警舆情的能力,是公安边防部队履行三大历史使命的保证。     

论公安现役高校在构建和谐社会中的角色定位

公安现役高校在公安教育体系中处于重要位置,承担着人才培养、科学研究和服务部队的重要任务,对构建和谐社会责无旁贷。准确定位公安现役高校在构建和谐社会中所扮演的角色,可以充分发挥职能作用,为构建和谐社会做出应有贡献。     

再论加强公安执法人员的法治观念

法制现代化是中国当前重大的社会主题之一,它是一个历史的、发展的过程。公安法治建设必然对国家法制现代化进程产生重大的影响。公安机关的性质、地位和作用决定了公安执法人员必须具有正确的执法思想。而法律至上观念、权利本位观念、分权制衡观念、正当程序观念对公安执法人员正确执法思想的形成有着直接的影响。     

论公安现役部队机关管理效能的发挥

当前公安现役部队机关在管理方面还不同程度地存在着不到位及越位问题,分析问题产生的原因,提出充分发挥机关管理效能应采取的对策,对机关服务和保障基层建设具有重要意义。     

一个新的类FEISTEL密码方案

分析了RSA和DES的算法优点和安全弱点,设计了一个新的密码算法方案。该方案以类FEISTEL结构为基础增强了左右两半部分结构的安全设计,利用了RSA进行密钥分配,并以序列密码算法的生成原理改变了固定密钥的缺点。该新方案具有一次一密的特点,给破译者获得大量的明密文对造成了很大的困难,可较好地抵抗差分分析与线性分析,是一种安全性较强的加密方案。     

Operational idealism: doctrine development of the Chinese People’s Liberation Army under Soviet threat, 1969–1989

This article analyses the doctrine development of the People’s Liberation Army (PLA) coping with the Soviet military threat between 1969 and 1989. In the 1970s, the PLA applied a doctrine of ‘active defence and luring the enemy into depth’ based on its traditional operational art. In 1980, the PLA decided to focus its doctrine on positional defence. In 1986, the PLA introduced ‘integrated operations and prioritised strike’, a generalised doctrine that originated from its war history. Many organisational and intellectual challenges in peacetime doctrine development contributed to the PLA’s operational idealism, including its aging leadership, command structure, attitude towards its previous experience, limited analysis of contemporary military developments, and failure in test and validation of doctrines. In the post-Cold War decade, many of these challenges persisted in spite of military modernization efforts. The ongoing military reform has to address these challenges and improve the PLA doctrine development in peacetime.     

The correlates of transatlantic burden sharing: revising the agenda for theoretical and policy analysis

While recent work has attempted to update the research agenda for transatiantic defense burden-sharing, there remain significant gaps between the public choice defense economics literature and the security studies literature. The presence of such a gap is unfortunate, because defense spending choices are likely shaped by factors identified by the public choice literature, as well as the strategic and cultural variables that the security studies literature tends to focus on, as well as domestic macroeconomic factors. The independent variables identified in recent qualitative literature are extremely useful analytically, and, fortunately, they have reasonable proxies in available quantitative data, which enables scholars to study them across large groups of countries and many years. This article builds upon such work to synthesize the most notable of the factors identified in the current literature, and offers some common analytical ground that will benefit both scholars and practitioners..     

Too much Western bias? The need for a more culturally adaptable approach to post-conflict security sector reform

The existing guidelines for security sector reform (SSR) tend to draw on theoretical work in the field of civil–military relations, which in turn has been derived from Western, liberal democratic models of governance. Although guidelines strongly advise that local culture and context need to be considered when drawing up objectives for post-conflict SSR programmes, this is not often reflected in practice. This article considers some of the reasons for this, citing both in-country challenges and donor-related issues, and suggests that one of the biggest problems is a lack of alternative, non-orthodox models of civil–military relations to draw upon. It is further suggested that elements of suitable alternative models may be found in states which possess political structures not entirely dissimilar to the Western, liberal democratic ideal, but which can offer different perspectives. Detailed research of these structures should produce a pool of sub-models which could then be employed to create bespoke, culturally appropriate objectives for use in post-conflict SSR programmes.     

地籍数据库点线拓扑一致性并行检查方法

针对拓扑检查算法复杂、计算量大,串行计算已远不能满足海量地籍数据高效拓扑检查需求的问题,在分析了点线拓扑关系的并行特点基础上,将界址点的数据划分方法与界址线的QR空间索引方法相结合,实现了界址点与界址线的并行拓扑计算。用某地区实际的界址点集与界址线集对点线拓扑并行检查进行实验。测试结果表明:并行检查算法的并行效率随着进程数的增加而有所衰减,但稳定在30%以上,加速比达到5以上,且相比于Arc GIS效率提升了30倍以上。并行检查方法以工具的方式集成应用于高性能地理计算平台中,应用效果良好。     

公安现役部队非战争军事行动训练面临的挑战与对策

当前,边境安全形势复杂、训练理念陈旧、部队勤训矛盾突出、训练内容与安排不合理、训练保障能力有限等主客观因素,制约着公安现役部队非战争军事行动训练的开展,对公安现役部队形成非战争军事行动战斗力构成了挑战。树立科学的非战争军事行动训练指导思想与理念,创新训练方法和手段,优化训练内容,加强教员队伍建设和训练基地建设,是改进非战争军事行动训练的有效对策。
