不同手机及不同通信网络通话录音质量评析

目的为送检手机通话录音质量的审查提供理论依据。方法提出一种定量化的语音检材质量评价标准,并对不同手机及不同通信网络下的录音进行质量评价。该标准基于主流鉴定设备,涵盖了声学语谱图共振峰个数及数值、基频参数、区域平均频谱等分析方法以及声纹比对测试。结果实验结果显示,不同条件下得到的通话录音质量存在一定的差异性,会对声纹图谱鉴定产生一定影响,但并不会造成本质性差异。结论语音同一认定中,对基于移动通信网络获取的检材录音应考虑到通话语音质量的差异性对检验的影响,并在鉴定分析中加以评估和克服。     

双层社会视阈下数据犯罪的法益规制思路

从网络到现实,双层社会迅速形成,相关犯罪亦从现实社会迁移至网络社会。如何应对伴生的新型犯罪形态,关键在于能否全面、清晰认知双层社会的链接点——数据。数据犯罪随双层社会固化而持续扩张,立法、司法均提出各自的应对思路,但规制现状并不乐观。以数据犯罪为核心,分析该犯罪形态在立法与司法领域的表征,并结合其技术与社会的双重价值属性,针对受损法益展开分析,最终实现对相关罪名适用的逻辑化探索。     

Mapping silent citizenship: how democratic theory hears citizens' silence and why it matters

Democratic theory hears silent citizenship as disengagement or disempowerment. Normatively, silent citizenship evokes the specter of civic passivity – of democratic citizens variably characterized by apathy, disaffection, selfishness, or a lack of political knowledge. Empirically, silent citizenship is linked to deficits of democracy – including voter turnout rates, the quality of political representation, and overall government responsiveness. One problem with these conclusions, however, is that we lack any systematic conceptualization of the range of different attitudes democratic citizens might hold in silence. This article seeks to fill in this conceptual gap by mapping the range of possible motivations for citizens to remain silent in developed liberal democratic systems. The key to doing so, I argue, is to distinguish between two measures of democratic citizenship: empowerment and communication. Separating these two measures reveals an entire spectrum of motivations for silence, which I organize into five distinct degrees of silent citizenship.     

A New Anti‐forensic Scheme—Hiding the Single JPEG Compression Trace for Digital Image

To prevent image forgeries, a number of forensic techniques for digital image have been developed that can detect an image's origin, trace its processing history, and can also locate the position of tampering. Especially, the statistical footprint left by JPEG compression operation can be a valuable source of information for the forensic analyst, and some image forensic algorithm have been raised based on the image statistics in the DCT domain. Recently, it has been shown that footprints can be removed by adding a suitable anti‐forensic dithering signal to the image in the DCT domain, this results in invalid for some image forensic algorithms. In this paper, a novel anti‐forensic algorithm is proposed, which is capable of concealing the quantization artifacts that left in the single JPEG compressed image. In the scheme, a chaos‐based dither is added to an image's DCT coefficients to remove such artifacts. Effectiveness of both the scheme and the loss of image quality are evaluated through the experiments. The simulation results show that the proposed anti‐forensic scheme can verify the reliability of the JPEG forensic tools.     

The Engage programme and the Government Communication Network in the UK, 2006–2010

The Engage programme was launched in April 2006 by the Government Communication Network (GCN) in the UK. As a civil service body supporting those in government working as press officers and in marketing roles, the GCN under the New Labour government in the period 2006–2010 was involved with the extension of the logic of marketisation to government communication. This article charts this process by examining key government policy documents from this period. The rationale for Engage rested on the assumption that government in the UK needed to adapt its communication approach to reach what were perceived as individualised consumers in society. The extension of the logic of marketisation to government communication that happened under Engage is shown to be consistent with the New Public Management approach to public services under New Labour.

现代诉讼的本质:全面理性的规范沟通

纠纷的成因是交往失败,而诉讼是重新交往解决纠纷的一种方式。将诉讼置于交往视野下,诉讼的沟通性便得以显现。无论是民事、行政还是刑事诉讼,均渗透着立足言语、实现主体间沟通的理念。诉讼通过外在规范特性保证主体间的沟通顺利进行,没有建制化程序的外在保障,沟通难以成效。诉讼的内在规范性是对诉讼规范性内涵的丰富,是一种内在的交往预设程序。经过对规范价值的内在化,诉讼交往主体形成自我约束,对诉讼规则、交往预设自愿主动承受,促进共识的实现和纠纷的解决。可以说,现代诉讼克服了传统职权主义模式或者当事人主义模式的片面理性,追求客观世界、主观世界和规范世界相融通的全面理性,保障司法公正、令人信服司法,达到司法真正权威。因此,诉讼区别于其他纠纷解决机制的最大不同,在于诉讼的本质是全面理性的规范沟通。     

新民主主义革命时期党群沟通机制有效运行的原因及启示

新民主主义革命时期中国共产党准确地把握社会形势,成功地宣传了党的方针政策,唤醒了民众的革命觉悟,有效地整合了各种社会资源,推动了新民主主义革命的胜利。研究新民主主义革命时期党群沟通的有效运行机制,对新时期进一步改善党群关系,加强党的建设具有重要的指导意义。     

电子商务立法刍议

我国的电子商务立法 ,可先采用条例形式 ,在今后实践中再充实完善。电子商务法应设置总则 ;未满十周岁的儿童不能成为电子商务的主体 ,所产生的法律后果由监护人承担 ;认证机构应具有电子商务的主体资格。对签署、证据、成立等行为应作出效力规定 ;各级工商行政管理局是电子商务的行政管理机关 ,各级邮电管理局也应成为管理机关。当事人在交易中违反民事法律 (规 )、合同约定的 ,均应承担民事责任。

网络通讯监听及其合理运用的政府保障

网络通讯监听是IT时代一种重要的技术侦查手段,其主要特征是监听主体的普遍性、监听对象的非确定性和监听范围的广泛性。主要类别包括即时单独网络通讯监听、即时多人网络通讯监听与非即时网络通讯监听。网络通讯监听存在正反两面价值冲突,我国应将其与网络舆情监测区分,树立令状原则并明确除外情形,建立其合理运用的政府保障。
