网络社区既是网络民族主义的动员场所,又是发生场所,与互联网时代粉丝社群的运作逻辑不谋而合.本文通过分析新浪微博"饭圈女孩出征"网络爬虫数据,探讨该事件的发展逻辑及扩散特征.研究发现,"饭圈女孩出征"是粉丝群体自发生成的、低组织化的网络行动,但粉丝群体的动员能力与扩散作用却被高估,他们在整个事件中只起到了"讨论酶"的作用,真正起到关键扩散作用的是传统媒体的网络账号.传统媒体官方账号的示范效应降低了普通用户的参与门槛,其后在娱乐营销号及不同领域意见领袖的带动下,共同促进该事件的深层扩散.通过社会网络分析发现,网络主体为紧密型的共意型扩散网络,其扩散链条较短;少数"异见"网络则呈现较长的扩散链条.

本文通过对2005年、2010年、2013年和2015年四组CGSS数据的分析,引入APC模型(Age-Period-Cohort Model)的分析视角,对“互联网接入”“互联网使用频率”“将互联网作为最重要的信息渠道”三个层次的互联网行为进行检验,探讨从2005年到2015年我国互联网的扩散历程.结论认为这十年间的互联网扩散是一种非线性的动态过程,是从“数字原生民”到“数字移民”之间的代际扩散和同辈影响综合作用的过程,并且体现出“后喻文化”的特点.由于区域发展的不平衡和世代效应的共同作用,我国互联网扩散的过程中存在“双重滞后”的现象,具体表现为互联网在农村区域的扩散严重落后于城市,中老年世代严重落后于年轻世代.互联网扩散中的“后喻文化”,是对数字代际鸿沟和区域鸿沟的自发性弥合机制.

一 2012年,公众态度的拐点 作为全世界第一人口大国,为了保障粮食安全,中国从1995年开始从国际市场进口大豆.中国的大豆进口量从1995年的30万吨飙升到2017年的9 500万吨,占全球大豆贸易的2/3.为什么要进口这么多大豆?为什么不扩大国产大豆的种植面积?很多中国公众对此并不理解.

与实名网络社区不同,匿名网络社区无法将线下社会资本转移到线上,用户必须依靠网络行为的形式来获取社会资本.本文提出了“匿名社区资本”的概念,使用网络爬虫对豆瓣网用户页面进行数据抓取,经过数据分析与建模,发现用户生产内容与社交等行为是普通用户在匿名网络社区中建立社会资本的基本方式,而社会资本是用户的网络社区行为在时间上持续累积的结果;同时,加入匿名网络社区的时间显著影响了匿名社区资本的获取,早期加入的用户在匿名社区资本的获取上具有一定的先发优势.

作为新媒体时代的“原生民”,青少年在传统媒体与新媒体之间的选择与使用是本文关注的焦点.本文采用对比分析的思路,以电视与手机媒体为例,采用详析模式的研究方法,得到影响青少年电视媒体选择与使用的主要变量是性别与学生两个变量,非学生群体的电视接触高于学生群体,女性青少年的电视接触高于男性青少年;影响青少年手机媒体选择与使用的主要变量是年龄与学生两个变量,在非学生群体中,不同年龄组的手机使用体现出了差异,而学生组则在几个对照组之间无差异.

The traditional multicast switch fabrics (MSF) are mainly developed from the unicast switch fabrics (USF). Owing to the bottleneck of the current USF, almost all the existing MSF are not able to achieve high efficiency orexcel-lentlarge-scale scalability. A wire-speed MSF based on lattice theory is presented. It cannot only meet the requirements of superior scalability and wire-speed multicast, and has low delay, jitter free, and no queuing cache performance advan-tages. It is proved that the MSF can both achieve optimal multicast performance and support priority-based multicast which can guarantee the multicast QoS (quality of service) in delay.

Ensuring high quality of service (QoS) of multicast video stream over a next generation network is a challenging issue, and how to implement the wire-speed multicast with hardware logical support in the network nodes of every hierarchy is a key solution to achieve high QoS multicast. Currently, the multicast packets are processed in this way, in which they are copied and then scheduled by ports, lastly, sent respectively. But this approach cannot ensure the high QoS in real-time applications. Moreover, the traditional hardware solutions can`t achieve large-scale scalability well owning to their own bottlenecks. In this project, using distributive lattice theory we have constructed a wire-speed multicast switching fabric based on a multi-path self-routing fabric structure which we developed previously, and implemented it on an Altera StratixIV FPGA chip. Also, we have investigated how the structure is used in large scale multicast switching fabric and designed the signaling system and control mechanism to support the process of self-routing and wirespeed fan-out copy of multicast packets.

行政法制监督是国家的一种法律制度,是国家行政管理基本环节中不可或缺的重要环节之一.依法行政是对国家行政管理的基本要求,而依法行政客观上就需要对行政管理活动实施监督,行政法制监督即是组织实施国家行政管理的一个重要方面.文章主要阐述了行政法制监督的概念及特征,分析了行政法制监督的基本内容,进而归纳了行政法制监督的基本体系.

At any time,reading is of great significance for the cultural heritage of human beings.The national reading has changed dramatically in China as digital age comes.The paper does not only summarize the results of previous research about the influence that the digital age has exerted on national reading and about concerned proposals,but also points out its limitations and shortcomings.The study shows that domestic scholars mainly investigated the status quo and change of reading.Then much attention has been paid to the following subjects including the medium and content of reading materials,people's reading be-havior and time they spent in reading.Besides,researchers also try to put forward some proposals on this topic.In the author's view,although some academic achievements have been made so far,their research results were mainly in the form of thesis rather than monograph,and most papers adopted qualitative research methods,lack of large-scale,systematic and scientific empirical research.Therefore,further study is needed on this issue.
