基于进化神经网络的入侵检测模型

当前的入侵检测技术主要有基于规则的误用检测和基于统计的异常检测。本文提出一个基于遗传算法的神经网络入侵检测系统模型，该模型将神经网络与遗传算法结合起来，利用神经网络自学习、自适应的特性，同时克服了神经网络易陷入局部最优，训练速度慢的缺点。该模型具有智能特性，能够较好地识别新的攻击。     

公共部门绩效评估存在的问题与对策

公共部门绩效评估在具体实施过程中出现不少问题,主要表现在评估主体单一化、评估指标体系不够全面科学、评估程序随意性较大及定性评估方法运用过多等。完善公共部门绩效评估体系,保证评估结果的合理有效,应建构多元化的评估主体、选择科学的指标体系、设计规范的评估程序、运用定性和定量相结合的综合评估方法。     

略论公安院校思想政治工作者的非权力影响力

暗网环境下恐怖主义信息挖掘与分析

随着互联网和人工智能的快速发展,恐怖主义活动方式变得更为隐秘。网络恐怖主义活动空间从表网的在线社区与视频分享平台转向暗网黑市交易和暗网论坛。针对暗网节点通信和交易信息高度匿名等特点,相应的反恐工作需要采取新的技术手段,以深度切入恐怖分子用于扩大影响的暗网空间。为此,可以设计和优化专门适用于暗网的聚焦爬虫工具,挖掘恐怖主义活动信息;可以搭建涉恐事件数据模型,分析恐怖组织可能的线下攻击手段;可以利用社会网络分析和超链接分析方法,定位暗网内恐怖主义隐蔽社区和危险用户集群。通过准确把握暗网中的匿名恐怖主义活动规律,抓住安全监控与防范的重点、难点,综合施策,以及适时制定和精准实施反恐网络安全策略,能够最大限度遏制暗网恐怖主义的危害,保护国家安全和人民利益。     

The Experience of Women Regarding Chilean Government Measures during the COVID-19 Pandemic

This study explores the experience of ten possible beneficiaries of the measures provided by the Chilean government during the first year of the COVID-19 pandemic through remote semi-structured interviews. The results show a scenario of improvisation. Instead of relying on solid gender equity policies, a patchwork of focused measures was implemented, which increased uncertainty and vulnerability. As a result, women experienced sorrow and despair while facing economic constraints and care tasks mostly on their own. This article shows that care remains invisible in politics while overwhelmingly evident at home. Social care policies are urgently needed.     

公共外交:信息时代的国家战略工具

信息社会的深入发展不但加强了各国经济的相互依赖,同时也引发了一场新的外交革命.为适应信息时代新的国际环境,世界各国政府正追求和发展一种新的外交形式--公共外交.公共外交是一国政府对其它国家民众施加影响的外交形式,即通过情报、国际信息、文化交流项目、媒体等手段影响其它国家的民众并制造舆论,为一国在海外创设良好的形象,进而增进国家利益的活动,是信息时代各国实现国家战略利益的重要工具.     

Whither the Liberal Democratic Model? Immigration Politics in Switzerland and Japan

A comparison of Japan's and Switzerland's immigration policies disclaims both globalist and public choice explanations that would predict a similar increase in immigrant numbers and an expansion of immigrant rights in liberal democracies. Although both countries have traditionally espoused a rather exclusionary approach towards immigration, Japan is unique in having hitherto succeeded in preempting large numbers of immigrants from entering the country and in having avoided the legal and societal integration of those migrants already present in its territory. In seeking to explain the different trajectories followed by immigration politics in Japan and Switzerland, despite their similar internal and external economic constellations, this article highlights the role of domestic institutions and norms in filtering economic pressure for immigration. Whereas these internal determinants explain to a large degree why Switzerland has become a country of immigration while Japan has not, the central factor explaining the recent expansion of foreign residents’ rights in Switzerland lies not so much in internal determinants but in the country‘s progressing approximation to the European Union and its single market. Notwithstanding these differences, the article concludes that Japan‘s greater resistance to change might now have reached a critical juncture, where demographic pressure and economic demand will make an opening up to increased labor migration unavoidable.     

关于治安拘留与罚款执行中相关问题的思考

治安拘留与罚款是治安管理处罚中经常适用的两种处罚方式,如何执行该两种处罚,已成为当前公安工作的一个重大问题。为了确保拘留与罚款的执行,应当深刻理会有关法律和司法解释的规定精神,充分考虑被处罚对象的实际情况,尊重和保护被处罚对象应当享有的权利,同时对有关法律、规章进行修改。
