Monte-Carlo Filesystem Search – A crawl strategy for digital forensics

Criminal investigations invariably involve the triage or cursory examination of relevant electronic media for evidentiary value. Legislative restrictions and operational considerations can result in investigators having minimal time and resources to establish such relevance, particularly in situations where a person is in custody and awaiting interview. Traditional uninformed search methods can be slow, and informed search techniques are very sensitive to the search heuristic's quality. This research introduces Monte-Carlo Filesystem Search, an efficient crawl strategy designed to assist investigators by identifying known materials of interest in minimum time, particularly in bandwidth constrained environments. This is achieved by leveraging random selection with non-binary scoring to ensure robustness. The algorithm is then expanded with the integration of domain knowledge. A rigorous and extensive training and testing regime conducted using electronic media seized during investigations into online child exploitation proves the efficacy of this approach.     

诽谤侵权案法理解构--张铁林诉周璇及《成都商报》名誉侵权案评析

在诽谤诉讼中,媒体报道失实的侵权责任主要应由言论主体承担,媒体只承担过错责任。新闻真实不等于客观真实,认定报道失实侵权的构成应尊重新闻传播规律。新闻报道与名誉权保护的利益平衡问题,实际上是根据新闻报道和人格权保护的价值,合理地确认各自权利边界的问题。     

案件新闻传播的三种类型

一起案件事实从发生到有关部门依据法律处理完毕是一个复杂的过程,这一事实形态呈现出发展的阶段性特征。对案件事实的整体传播和对某一阶段事实的传播,所产生的传播效果是有区别的,事实的不同阶段所表现出的不同寓意,决定了传播方式和原则的不同。依据不同阶段案件事实的特征和传播者所期待的传播效果,案件新闻可以分为预警新闻、案件本体事实报道和案件完全事实报道等类型。对案件的分类传播是实现案件新闻传播正面效应的必要途径和操作技巧。     

论公共安全危机事件应急处置过程对新闻与信息的管理

公共安全危机事件具有较高的新闻价值。新闻媒介在公共安全危机事件应急处置过程中的作用具有双重性。对新闻与信息的管理涉及应急处置现场的管理控制,信息的发布,管理机构与新闻媒体之间公共关系的处理,谣言与流言的控制等几个方面。它主要起到监督、警示、沟通、引导与激励的作用。我国目前对新闻与信息的管理尚缺乏足够的重视,应急处置现场的相关管理有待完善。

Australian news media’s representation of Cate McGregor,the highest ranking Australian transgender military officer

To date, no academic analysis has investigated the representation of transgender individuals by Australia’s news media (ANM). This paper conducts a discourse analysis of ANM’s representation of Cate McGregor, the highest ranking Australian transgender military officer. The author offers this analysis as a case study in which 28 articles were selected from a three-year period, beginning November 2012, when McGregor ‘came out’. By employing a feminist and transgender theory framework the author concludes that, on the one hand, ANM reproduces traditional transgender tropes (e.g. publishing ‘before/after’ photographs). On the other hand, ANM gives voice to McGregor’s views pertaining to living as a woman and a transgender woman, which are aligned with transgender theory. Thus, this author argues that ANM engages in a remediation of transgender theory. McGregor acknowledges that she has enjoyed the privilege of being socialized as a man and therefore her life as a woman, a transgender woman is different to other women. Moreover, as an ‘out’ transgender woman she is refusing to ‘pass’ and hide her sex/gender history. Subsequently, McGregor views on what it means to be a man, a woman, and a transgender woman, are disruptive to sex/gender normativities and she thereby embodies a ‘gender fuck’.     

Market Demand for Civic Affairs News

This paper uses time series methods to test the relationship between civic affairs content and audience share for the ABC, CBS, and NBC evening news in the mid-1990s. Because these programs competed in the same market, but varied the amount of their civic affairs coverage, they present an excellent opportunity to analyze this relationship. The study uses hand-coded news abstracts and O.J. Simpson murder trial coverage as separate measures of news content. The study finds that lower levels of civic affairs content and higher levels of O.J. news are associated with greater audience share.     

Role of Social Media in the 2016 Iowa Caucuses

Social media have become an indispensable tool in modern political campaigns, yet little is known about their impact, especially at the important primary and caucus stages of the US presidential elections. This study investigates the effects of visiting political party and candidate websites as well as following presidential candidates, posting political comments, and liking or sharing political content on social media on participation in the primary stage of the 2016 US election. The results of a precaucus survey in Iowa show that active use of social media tends to have positive effects, while passive social media use has a negative impact on likelihood of caucus attendance. Recommendations for campaigns include redirecting attention away from passive website viewing and developing social media content that will generate likes and shares.     

Laughing Our Way to a Stronger Democracy: Political Comedy’s Potential to Equalize Political Interest in Community College Students

What effect does political comedy have on political interest? Through an experimental design, changes in political interest are measured through a pre and posttest, comparing groups randomly assigned to watch The Daily Show, NBC Nightly News, Entertainment Tonight and a no-exposure group. Models indicate political comedy significantly affects political interest, measured through a unique 40-point index.     

News Media Use and Political Engagement Among Adolescents: An Analysis of Virtuous Circles Using Panel Data

This study analyzes reinforcing spirals between news media use and two manifestations of political engagement: political interest and participation intention. Drawing on a three-wave panel study among adolescents, we test the Virtuous Circle Thesis (VCT) in both an online and an offline setting, by distinguishing between selection effects and media effects as key ingredients of the VCT. Overall, the findings lend mixed support to the general argument. While the relationship between specific forms of news media use and political interest appears to be driven primarily by selection effects, reciprocal relations were found mainly between television news and participation intention. The VCT assumption of reciprocal influences was supported most clearly when adolescents’ total news media use was considered. Taken together, virtuous circles appeared to operate rather similarly online and offline.
