Information Campaigns and (Under)Privileged Citizens: An Experiment on the Differential Effects of a Voting Advice Application

Information campaigns are key elements of elections. Past research has established the importance of campaigns in informing and educating citizens, and ultimately strengthening participatory democracy. While the Internet has increased the possibilities to disseminate information campaigns and eased access to political information, it is still debated whether online campaigns are effective in stimulating political interest and participation among the general public. The issue is not only one of access, but also of use of information. The investigation of main effects of campaigns obscures the fact that citizens may not use information in the same way and reap the same political benefits. In this study, I examine the conditional effects of a new type of Web information campaign, Voting Advice Applications (VAAs), on the political engagement and electoral participation of citizens with varying levels of education. By investigating who benefits most from using these apps, I evaluate whether VAAs reinforce patterns of participation or mobilize new people in politics. Building on political behavior research, communication theory, and social psychology, I study the differential effects of VAAs with an innovative randomized field experiment design. The results confirm that VAAs can stimulate the political engagement of the public. However, there is no significant impact on electoral participation. In addition, the evidence shows that VAAs work differently for more or less educated citizens, and that the lower educated users benefit the most from VAAs as they become more interested in the election and more motivated to vote.     

侦查实验相关问题探讨

作为侦查学原理中必须涉猎的内容,侦查实验在诸多方面尚缺乏全面、系统的研究。本文通过对侦查实验的界定,侦查实验的分类,侦查实验与审判实验和审查起诉实验的异同,侦查实验的法律规制等相关理论问题的粗浅探讨,希望对其理论甚至实践操作体系的日臻完善,能有抛砖引玉之效。     

高等学校法学刑侦实验室建设模式的研究与探索

通过对高等院校法学刑侦实验室现状的分析研究,针对传统法学教学模式只注重法学理论、弱化实践性教学环节,导致学生操作能力不强的现状,紧紧围绕法学教学活动中以刑事侦查实践为中心,以提升学生的动手及适应社会能力水平为目的,夯实本科教学基础,提出以体验性模拟现场实景教学法为手段,构建合理的法学刑侦实验室建设的模式。     

公安高校网络警察培养实验教学体系研究

为了满足各级公安机关对网络警察的需求，很多公安高校增设了信息安全等相关专业，而网络警察培养是一门实践性非常强的学科，公安高校信息安全专业实验教学体系包括基础实验、计算机安全实验和公安业务实验三大部分，网络信息安全类和计算机取证类实验的实验内容、实验课程、实验项目、实验室建设工作值得重点分析研究。     

From voter ID to party ID: How political parties affect perceptions of election fraud in the U.S.

This paper uses a survey experiment to assess what individuals understand about election fraud and under what circumstances they see it as a problem. I argue that political parties are central to answering both these questions. Results from the 2011 CCES survey suggest respondents are able to differentiate between the relative incentives of Democrats and Republicans where fraud tactics are concerned, but whether voters see these tactics as problematic is heavily influenced by partisan bias. The results show little support for the notion that partisan ideology drives fraud assessments, and suggest support for the idea that individual concerns for fraud are shaped a desire for their preferred candidate to win. These results offer insights that might be applied more broadly to questions of perceptions of electoral integrity and procedural fairness in democracies.     

论新形势下物证检验实验教学的改革与探索

Implementation of a semi-automated processing system for DNA profiling of forensic casework samples

The concept for a semi-automated processing system for DNA analysis of crime scene samples was developed at the Landeskriminalamt Baden-Württemberg (LKA BW) and comprises the extraction of genomic DNA from human cells by ChargeSwitch^® magnetic bead technology (CST), quantification of purified DNA by real-time PCR, amplification of short tandem repeats (STRs) by PCR and DNA fragment length analysis of STRs by capillary electrophoresis. Three liquid handling workstations from Tecan, a real-time PCR device and a 16-channel capillary electrophoresis (CE) system, both from Applied Biosystems (AB), are linked via laboratory data network. Transmission and management of sample and analysis data is enabled by a Laboratory Information and Management System (LIMS). Suitability for a wide range of stain types, early exclusion of DNA-free samples, barcode sample identification and prevention of cross-contaminations guarantee efficiency and high quality standards.
