维护国家安全 规制网络舆论

近期发生的家乐福、CNN 报道事件,引起了一连串的反应,先是网络上网民的激烈讨论,接着是媒体的报道,之后是蔓延到全国各地的有组织的活动,直至最后政府的表态。这一连串的事件波及国家政治和经济,对社会秩序造成了一定的冲击。在这次事件中,网络舆论再次展示了其强大的力量,通过网络舆论展示了中国人民的巨大凝聚力,有力反击了西方敌对势力的无稽言论。但在看到网络舆论成为维护国家权益的工具的同时,网络舆论中存在的巨大安全隐患也让人担忧。

新冠疫情相关社交媒体谣言传播量化分析

新冠肺炎疫情的爆发伴随着大量的谣言在社交媒体平台传播,对网络秩序和社会稳定产生了不良影响.已有的疫情相关社交媒体谣言传播量化分析研究仅对谣言内容等单一传播要素展开分析,而忽略了构成信息传播的其他基础要素,包括传播者、受众以及传播效果等.同时,这些研究的谣言数据与真实的社交媒体谣言数据也存在分布偏差和信息缺失.因此,基于新浪微博平台对新冠疫情相关社交媒体谣言的传播展开更加全面的量化分析.具体而言,首先对谣言传播内容进行分析,包括其主题分析、涉及地区分析、事件倾向性分析以及情感分析;进一步对谣言参与用户进行分析,将参与用户分为3类:造谣者、传谣者和辟谣者,并分别对其基础属性、关注主题、个体情绪以及自网络属性进行探究;最后对谣言引发舆情进行分析,探究其情感的整体分布、与主题、关键词和地区的关系、以及情感的演变规律.该研究首次从信息传播的各个基础要素层面对疫情相关的社交媒体谣言传播展开量化分析,不仅对新冠肺炎疫情相关谣言传播有了更全面深刻的认识,同时对突发公共事件的谣言研究和谣言治理也具有十分 重要的价值.     

记者和PR

我到杂志时间不长,因此5周年的专题,我不敢胡言乱语,唯有祝福. 但我在行业媒体有几年,一个最深的体会就是与PR打交道.行业媒体做得最多的是产业报道和应用报道,这两种报道在进行选题策划时,一般会考虑到两头,一头是用户(消费者),一头是厂商.PR代表了厂商,是厂商对外宣传的把关人.     

媒体舆论引导仿真

使用multi-Agent的建模思想,以现实为基础建立了一个舆论涌现的仿真模型.该模型主要由个体和媒体以及它们之间的规则组成.个体的属性包括了个体之间的信任度、个体观点的可信度和个体的从众性;媒体的属性包括媒体的影响范围和权威度.规则包括个体交互规则和个体与媒体的交互规则.通过仿真证明了模型是合理的,并且用该模型来仿真媒体对舆论演化的引导作用,从媒体的数量和报道频率2个方面研究媒体在舆论形成过程中的引导作用,结果发现积极媒体的数量越多对舆论的引导作用越强,媒体的报道频率增加会对舆论的形成产生积极效果,但是超过一定次数时对舆论的影响作用有限.最后通过对模拟结果的分析,提出了通过媒体来引导舆论的方式.     

公安大数据分析在疫情人员管控中的应用研究

在疫情中,警务人员起到了不可替代的重要作用,除传统的外部人员管控等工作外,还充分利用公安大数据进行重点人员排查、密切接触人梳理等工作,梳理了常用的公安大数据与疫情中重点用到的公安大数据,研究汇总公安大数据在疫情管控中的工作思路和具体应用方法,细化不同场景下不同数据的使用,对类似工作提供了一种可行化、通用化的模式.通过研究,明确哪些公安大数据在疫情管控中的哪些方面如何起到作用.如:趋势走向、接触人员、人员流动等,为领导和专家决策提供数据和为防控提供依据.运用大数据分析,支撑服务疫情态势研判、疫情防控部署以及对流动人员的疫情监测、精准施策.     

基于Flask框架的疫情数据可视化分析

在新冠肺炎疫情背景下,通过数据爬虫技术获取开源的疫情数据,经数据处理后形成数据集,利用可视化技术进行数据可视化与数据分析.介绍了数据爬取与处理方法,利用Python语言的Flask框架等可视化技术完成疫情数据可视化,从多角度、多方面展示与分析疫情数据.帮助民众充分了解全国各地的疫情情况、疫情发展趋势以及疫苗接种情况.

数字媒体艺术泛指使用各种数字、信息制作的各类形式的艺术作品.其表现形式包括:信息与艺术设计、数字影像艺术、虚拟现实、网游、数字图像处理技术、移动媒体及影视广告设计等诸多方面.本文就中国数字媒体的发展前景及现状以及创新观念方式如何推动数字媒体艺术的发展等方面进行研究与分析,目的希望大众能对数字媒体艺术有客观的认识,了解观念创新与数字媒体艺术发展之间的重要性,以促进文化创意产业和数字媒体的共同发展.     

基于Twitter的流感疫情可视化系统

介绍了当下社交媒体的蓬勃发展以及基于社交媒体数据的多领域应用,阐述了利用Twitter数据对流感疫情监测的优势和可行性,着重论述了基于Twitter的流感疫情可视化系统的详细设计和具体实现,并讨论了系统的意义和应用方向.     

“隐制裁”影响下的社交媒体平台全球化发展路径

2023年,一些西方国家颁布的一系列禁令使社交媒体平台TikTok的发展蒙上阴影。从网络安全的视角分析,针对TikTok的禁令是基于风险防范而非事实的网络安全想象。实际上,针对TikTok的禁令是西方国家试图在网络空间与精神世界进行“断链脱钩”的“隐制裁”。在此基础上,可以归纳提出“隐制裁”的概念内涵与特征,并从国家与企业两个层面提出应对隐制裁的社交媒体平台未来发展之路,以便为未来社交媒体平台的全球化发展提供参考。     

Assessing Ideational and Evaluative Skills and Creative Styles and Attitudes

This article describes the rationale for the multiphase creative problem solving process, and reports the findings from an empirical investigation conducted to facilitate the problem solving of managers. The ideational skills of the managers were assessed before and after training in a complete process of creative problem solving, along with their ideational attitudes, creative problem solving style (i.e., generator, conceptualizer, optimizer, or implementor), and evaluative skill (i.e., ability to recognize original ideas). The most important findings indicated that the training had a significant impact on the evaluative accuracy of the managers. They were significantly more accurate in their judgments about original ideas after training, both in their identification of original ideas and their recognition of unoriginal ideas. After training, the managers also gave more solutions and more original solutions to problems. Finally, several variables (e.g., the “preference for active divergence” attitude, and the conceptualizer process style) seemed to moderate the impact of training. Training was therefore effective, with specific effects that can be predicted from pre-training individual differences in attitudes and process style.     

Semantics and verification of monitors and systems of monitors and processes

In this paper we present a sound and complete semantics for the monitor concept of C.A.R. Hoare. First a method for specification of monitors, introduced by O.-J. Dahl, is reviewed. This method is based on the relation between the historic sequence of monitor procedure calls and the historic sequence of monitor procedure exits. Based on such specifications and our new monitor semantics we present a method by which it is possible to prove that a concrete monitor is an implementation of an abstract one. In the last part of the paper an axiomatic semantics for systems of concurrent processes and monitors is introduced. The method supports verification by separation of concerns: Properties of the communication to and from each process are proven in isolation by a usual Hoare style axiomatic semantics, while abstract monitors are also specified in isolation by the method reviewed in the first part of the paper. These properties of the components of the system are then used in a new proof rule to conclude properties of the complete system. Stein Gjessing received a Ph.D. (actually a Dr. philos.) from the University of Oslo (Norway) in 1985. Presently he is an Associate Professor at the Institute of informatics, University of Oslo, Norway. Dr. Gjessings research interests are in the area of concurrent and distributed programming, operating systems, formal specification and verification and programming languages.     

Integrating and automating analysis and optimization

The development of an interface coupling program on personal computers for an analysis software system such as ANSYS, SAP, etc. and an optimization software system, MOST, is presented. By controlling and directing the communications the interface coupler integrates the two programs while retaining their versatility and interactive features. The integrated system is used to solve a numerical example of active noise control for a three-dimensional enclosure, in which an energy density level of control points is minimized by adding the sound source to cancel the unwanted noise. The interface coupling program automates with relatively low cost the iterative process for designing an engineering system, remaining flexible in acoustical modelling and efficient in equation solving. Also, the coupling interface is developed in a general-purpose way so that it can be expanded easily to integrate more analysis software packages of different kinds.     

Rank and select revisited and extended

The deep connection between the Burrows–Wheeler transform (BWT) and the so-called rank and select data structures for symbol sequences is the basis of most successful approaches to compressed text indexing. Rank of a symbol at a given position equals the number of times the symbol appears in the corresponding prefix of the sequence. Select is the inverse, retrieving the positions of the symbol occurrences. It has been shown that improvements to rank/select algorithms, in combination with the BWT, turn into improved compressed text indexes.
