Digital Technology and Cultural Heritage Sites in the City of Tshwane

This article examines the feasibility and sustainability of digital technology to promote cultural heritage sites in the City of Tshwane (CoT), South Africa. Post-Apartheid development imperatives compel the CoT to construct new cultural sites. Over time, the number of visitors to the places declined. The CoT introduced digital technology to collect and repackage information on some of the cultural edifices to add value to them. However, the absence of heritage/digital technology impact analysis and cultural policy in the CoT could compromise the program. The article recommends further introduction of important facilities and services in the sites to increase public interest.     

The Intellectual and Cultural Dimensions of International Relations: Present Ironies and Future Possibilities

Reported is a study that focused on the Millennial Generation and potential differences in viewing an exhibition in person versus online. The exhibition featured the artwork of Paul-Henri Bourguignon, whose extensive body of work includes a variety of paintings and drawings that employ a wide range of styles. Some viewers traveled to the physical space of a museum gallery, while others viewed reproductions of the same works on the Internet. Informants engaged in reflexive self-interviews using Dervin's Sense-Making Methodology. The authors compare viewers’ responses to works experienced in person versus online and discuss implications.     

Digital Network Repertoires and Organizational Hybridity

This article summarizes a study of 37 televised debates on political issues in Denmark, conducted live before representative audiences, with polls on the issues before and after each debate. These debates are of interest to research because they were authentic, and they supply data indicating persuasive effects. Various rhetorical features were observed and related to debaters success in attracting votes. In a qualitative interpretation of the observations, we suggest that debates such as these are likely to be won by debaters whose argumentation is fair and thoughtful. Audiences may respond differently depending on whether they are voters or merely viewers. The debate format may enhance such a response, for the benefit of the democratic process.     

A Novel Forged Image Detection Method Using the Characteristics of Interpolation

Development of digital image‐editing programs has enabled us to be widely exposed to forged digital images surrounding us. Such forged images have been dispersed through the Internet, newspaper articles, and magazines, and in particular, the information contained in these unverified images happened to be regarded as true. As a result, the forged images provided wrong information for individuals and society, thus sometimes creating social issues. In order to solve such problems, this study was aimed to suggest the methods of identifying the veracity of forged images. In this way, it suggested re‐interpolation algorithm. Namely, the study re‐interpolated in identical arbitrary values both the interpolated and un‐interpolated regions based on the interpolation used a lot in forged, confirmed discrete fourier transform (DFT) characteristics of these two regions, and embodied a detection map for the final forged images, using the subtraction value between two regions in DFT characteristics.     

An Analysis of Advertisements: A Lens for Viewing the Social Exclusion of Women in Police Imagery

This study examines whether there are differential relationships among trauma exposure, familial risk and protective factors, substance abuse, and posttraumatic stress disorder (PTSD) among incarcerated and non-incarcerated women. A case-control method was used to match 100 incarcerated women with 100 women in the general population. Incarcerated women had a significantly higher risk of trauma exposure as compared with controls, with odds ranging from 1.7 to 3.7. When group was controlled, exposure to sexual or physical trauma significantly increased the odds of PTSD (odds ratio = 5.0; p < .05), as did substance use in response to traumatic distress (odds ratio = 8.9; p < .001). Family-related characteristics did not appear to moderate this relationship. The findings suggest that incarcerated women are at high risk for PTSD given their high rates of trauma exposure and apparent lack of appropriate coping mechanisms; the results support the use of trauma-specific interventions for this population.     

数字签名的技术与法律分析

数字签名的目的和作用主要是证明合同主体的真实身份、证明合同的保密性和完整性以及证明合同主体对合同的确认。而其证明力的有无及证明力的大小又是以技术作保障的,换言之,安全性是证明力的前提和基础,是法律承认其效力的基石。     

活体跟骨数字X线片性别判定

目的应用数字X线摄影方法测量跟骨,评估5项测量指标在法医学性别判定中的价值。方法393例受试对象随机分组,实验组334例(男性148例,女性186例),验证组59例(男性26例,女性33例)。每一受试对象按照规定投照方法摄跟骨侧位DR片,分别测量5项跟骨长度指标。方差分析检验实验组各项指标性别间差异,Fisher判别分析及多元逐步判别分析建立性别判别函数。验证组样本数据回代,前瞻性评估判别效能。结果5项指标性别差异有统计学意义(P<0.001)。共建立了6组性别判别函数,性别判断正确率在78.4%～88.9%之间;回代检验,判断正确率在79.7%～86.4%之间。结论跟骨侧位数字X线片5项长度测量指标代入判别函数进行性别判定的方法可为法医学个人识别中的性别判定提供帮助。     

数字签名与电子签名法

《中华人民共和国电子签名法》已经开始实施,本文对电子签名的定义、使用的范围及其作用作了介绍,并对电子签名技术实现中的一些技术问题如公钥基础设施PKI的功能,三种最常用的公钥算法,数据摘要与哈希(Hash)函数的作用与要求,常用的哈希算法MD5与SHA-1,以及数字签名的技术实现过程作了一些探索。     

美国自由贸易协定中数字产品贸易的规制研究

在WTO关于数字产品贸易的谈判中,美国一直主张适用GATT和零关税,但遭到了欧盟等的坚决反对。之后,美国通过自由贸易协定的形式推行其政策立场。在自由贸易协定中设立＂电子商务章＂,以有别于货物贸易和服务贸易;在跨境服务章中采用限制性清单的方法,力争为数字产品贸易提供较大程度的自由化。美国通过自由贸易协定规制数字产品的模式尽管值得商榷,但确实为WTO规制数字产品贸易进行了先行的尝试,拓展了其国内政策的国际空间。美国这种竭力将其国内政策推行为国际共同立场的做法,对于经常主张与国际接轨并被动接受国际规则的中国来说,无疑值得借鉴。     

数码相片的证据作用探析

数码相机在公安司法工作中的应用非常广泛,用数码相机所获取的数码相片,因其的易修改性,使人们对其证据作用产生了怀疑,笔者认为,依据我国法律,数码照片可以作为证据使用,但必须经严格的审查判断。
