浅谈数字图像真实性的检验鉴定

随着IT技术的迅速发展,数字图像的采集越来越方便,但通过数码设备形成的数字周像非常容易被篡改。当前国内外均存在照片伪造现象,因案件性质不同,影响的范围也有所差异,但共同的目的都是为了私欲而混淆是非。这就要求我们必须不断提高检验鉴定的水平,还原事实真相。     

Web Content Management Systems: An Analysis of Forensic Investigatory Challenges

With an increase in the creation and maintenance of personal websites, web content management systems are now frequently utilized. Such systems offer a low cost and simple solution for those seeking to develop an online presence, and subsequently, a platform from which reported defamatory content, abuse, and copyright infringement has been witnessed. This article provides an introductory forensic analysis of the three current most popular web content management systems available, WordPress, Drupal, and Joomla! Test platforms have been created, and their site structures have been examined to provide guidance for forensic practitioners facing investigations of this type. Result's document available metadata for establishing site ownership, user interactions, and stored content following analysis of artifacts including Wordpress's wp_users, and wp_comments tables, Drupal's “watchdog” records, and Joomla!'s _users, and _content tables. Finally, investigatory limitations documenting the difficulties of investigating WCMS usage are noted, and analysis recommendations are offered.     

Temporal Trends in Rainwater Tank Suicides in Rijeka,Croatia—A 30‐year Study

Although drowning in rainwater tanks is a generally rare phenomenon, this method for suicide has been observed in parts of Croatia. Review of autopsy records at the University of Rijeka, Croatia, was undertaken from 1987 to 2016 to examine this phenomenon. Of 469 drowning deaths, there were 35 suicides in rainwater tanks (7.5%). Overall drowning deaths showed no temporal trends. In contrast, suicidal drownings in rain water tanks showed a marked decline over the years, with 15 cases in 1987–1991, seven in 1992–1996, six in 1997–2001, six in 2002–2006, one in 2007–2011, and none in 2012–2016. Thus, suicidal drowning cases as a percentage of overall drownings dropped from 18% to zero (p<0.001). This study reports a very unusual method of suicide that may have occurred because of the ready availability of large water reservoirs in homes. The recent fall in numbers may relate to less reliance on domestic reservoirs of water.     

Associations between different motivations for animal cruelty,methods of animal cruelty and facets of impulsivity

ABSTRACT

Associations between specific motivations for animal cruelty, particular methods of animal cruelty and different facets of impulsivity were explored among 130 undergraduate students. Participants completed an adapted version of the Boat Inventory on Animal-Related Experiences (BIARE) which asked participants to state whether they had intentionally harmed or killed an animal, the species of animal(s) involved, their motivations for harming or killing the animal(s) and the method(s) used. Participants also completed the Impulsive Behavior scale (UPPS-P) which assesses five facets of impulsivity. Over half of the sample (55%) reported committing at least one act of animal cruelty, and dogs were the most commonly abused species of animal. The most frequently reported motivations were Prejudice, Amusement, Control (of an animal), and Retaliation (against an animal), and the most frequently reported methods were Beating/Kicking, Squashing, Throwing an object at an animal, Shooting, Drowning and Burning. Significant associations were found between particular motivations and methods, as well as between particular methods of animal cruelty and facets of impulsivity. Findings have implications for theoretical models of animal cruelty perpetration as well as offender assessment and treatment.

Usability and Digital Inclusion: Standards and Guidelines

This article aims at discussing e-government website usability in relation to concerns about digital inclusion. E-government web design should consider all aspects of usability, including those that make it more accessible to all. Traditional concerns of social exclusion are being superseded by fears that lack of digital competence and information literacy may result in dangerous digital exclusion. Usability is considered as a way to address this exclusion and should therefore incorporate inclusion and accessibility guidelines. This article makes an explicit link between usability guidelines and digital inclusion and reports on a survey of local government web presence in Portugal.     

Combining the Strengths of Qualitative Comparative Analysis with Cluster Analysis for Comparative Public Policy Research: With Reference to the Policy of Economic Convergence in the Euro Currency Area

Qualitative Comparative Analysis (QCA) is a well-established method for comparing national public policy similarities and differences. It is argued that Cluster Analysis can add additional benefits to such research when used concurrently with QCA. Cluster Analysis provides a better method for the initial exploration of multivariate data and examining how countries compare because it can work with the full range of available interval data while patterns are created and viewed. This provides the best first method for exploring patterns and likely groupings of countries. QCA then provides a more robust method for theorizing about the construction of such groupings and their relationship around similar variable scores. QCA makes such theorizing transparent. The research example used to illustrate the benefits of combining Cluster Analysis and QCA is an analysis of the evolving of macroeconomic policy for the countries sharing the Euro, comparing 2005 (precrisis) with 2010 (postcrisis).     

政党适应性视角下的党内巡视制度

改革开放以来,面对不断变迁的社会结构和充满挑战的外部环境,我党一直在进行着适应性变革。党内巡视制度的建立符合政党适应性的要求,可以消解党适应性变革中社会基础扩大给党执政带来的影响,是提高党的建设科学化水平的重要一环。从政党适应性视角看,党内巡视制度面临一些挑战,包括存在陷入＂钱穆制度陷阱＂的可能,存在信息化时代的挑战,对巡视制度的理论研究尚显薄弱,等等。因此,应加强党内监督制度体系建设,坚持群众路线,通过改革的进一步深入完善党内巡视制度,从而提高政党适应性。

Core Consensus,Strategic Variations: Mapping Arts Management Graduate Education in the United States

This study is the first comprehensive curricular comparison of graduate arts management programs in the United States. Its principal finding is that there exists considerable curricular convergence among arts management programs and that their differences may be exploited strategically. Through extensive curricular analysis and in-depth conversations with faculty, this study makes both conceptual and methodological contributions to the field—conceptual because it provides an empirical basis for the definition of arts management as a formal academic discipline in its own right and methodological because it proposes a framework to effect a systematic comparison of arts management program curricula.
