电子证据带给行政执法工作的挑战与对策

电子证据作为一种崭新的证据种类已经在执法实践中发挥了比较大的作用。但由于现行法律还没有对电子证据给予明确的规定,因此,有关电子证据的概念问题、其法律地位的界定问题、其法律价值的评价问题等应是电子证据研究的首要问题。此外,研究电子证据可以对具体的行政执法工作提供有益的帮助。     

台湾地区民事证据保全制度改革及其借鉴意义

为了彻底改造所移植外国法,更新传统诉讼观念,解决诉讼拖延、效率低下和诉讼成本高昂问题,我国台湾地区于20世纪末、21世纪初就证据保全制度从立法理念到具体内容进行了重大变革。新证据保全制度所蕴含的保障程序主体权、扩大诉讼解决纠纷能力、疏减讼源及预防纠纷发生的理念,以及为贯彻该等理念在设置具体制度时,扩大证据保全范围、规定并引导当事人于证据保全程序中达成协议和严格证据保全的程序保障的做法,对大陆证据保全制度的改革具有借鉴作用。     

Empirical Evaluation of the Reliability of Photogrammetry Software in the Recovery of Three-Dimensional Footwear Impressions

This paper examines the reliability of Structure from Motion (SfM) photogrammetry as a tool in the capture of forensic footwear marks. This is applicable to photogrammetry freeware DigTrace but is equally relevant to other SfM solutions. SfM simply requires a digital camera, a scale bar, and a selection of oblique photographs of the trace in question taken at the scene. The output is a digital three-dimensional point cloud of the surface and any plastic trace thereon. The first section of this paper examines the reliability of photogrammetry to capture the same data when repeatedly used on one impression, while the second part assesses the impact of varying cameras. Using cloud to cloud comparisons that measure the distance between two-point clouds, we assess the variability between models. The results highlight how little variability is evident and therefore speak to the accuracy and consistency of such techniques in the capture of three-dimensional traces. Using this method, 3D footwear impressions can, in many substrates, be collected with a repeatability of 97% with any variation between models less than ~0.5 mm.     

Parental Alienation in U.S. Courts, 1985 to 2018

Courts have been dealing with alienating behaviors in high conflict family litigation for hundreds of years. Experts in the behavioral sciences have been writing about mothers and fathers manipulating their children to disparage the other parent for more than seventy years. But in the last two decades some social scientists and legal professionals have questioned the legitimacy of parental alienation as a concept and its admissibility in child abuse and child custody litigation. This study was designed to examine the extent to which courts in the United States have found the concept of parental alienation material, probative, relevant and admissible. Thirty‐four years of cases were found with a WESTLAW query and analyzed. Cases were selected for study only if the record reflected that a judge or an independent expert found the concept of parental alienation to be of value in the litigation. Results illustrate increasing awareness of the concept and document its admissibility in every one of the United States. The numbers, sex of the alienating parent and prevalence of significant custody changes are discussed. Limitations inherent in this form of quantitative analysis are also discussed with recommendations for future research.     

Facts,power and global evidence: a new empire of truth

Abstract

What are the epistemological and political contours of evidence today? This introduction to the special issue lays out key shifts in the contemporary politics of knowledge and describes the collective contribution of the six papers as an articulation of what we describe as a ‘new empiricism’, exploring how earlier historical appeals to evidence to defend political power and decision-making both chime with and differ from those of the contemporary era. We outline some emerging empirical frontiers in the study of instruments of calculation, from the evolution of the randomized controlled trial (RCT) to the growing importance of big data, and explore how these methodological transformations intersect with the alleged crisis of expertise in the ‘post-truth’ era. In so doing, we suggest that the ambiguity of evidence can be a powerful tool in itself, and we relate this ambiguity to the ideological commitment and moral fervour that is elicited through appeals to, and the performance of, evaluation.     

Connecting research and practice: Perspectives on the role of manualized programs in youth work

While there is a strong movement in favor of the use of manual-based programs in the arena of social care, there is a view that such programs are not applicable in the more fluid setting of youth work, which operates informally, using dynamic and organic methods. A critical pedagogical approach to youth work engages young people by encouraging them to become inquisitive, to question why things are the way they are and to pose problems through which they can learn. For some, manualized or evidence-based programs are not seen as having a role in such contexts. However, to date, the international debate in relation to this issue has been limited by an absence of published studies focusing specifically on strategies to implement evidence-informed practice in youth work contexts. This article aims to address this gap in the literature. The Irish national youth organization Foróige, which works with more than 56,000 young people in Ireland on an annual basis, has developed a range of manualized evidence-informed resources to support its youth work over recent years. Drawing on research findings from a range of studies conducted with youth workers focusing on implementation of these resources, the article explores the benefits and tensions associated with the use of program manuals in a youth work context. The findings suggest that such resources have a valuable role to play in youth work if designed in collaboration with youth workers, showing respect for core youth work values and allowing for flexibility and adaptability in implementation.     

以科技侦查推动侦查模式的根本变革

现代社会,犯罪数量持续高发,犯罪类型不断衍生,犯罪手段不断升级,犯罪活动方式不断变化,给侦查工作带来了许多新的挑战。如果仍然以“人证为主”的侦查模式作为侦查工作的主导模式,必然导致侦查成本成倍增加,破案率大幅下降。侦查模式由“人证”向“物证”的转变势在必行。在实现刑事侦查模式的转化中,现代科学技术在实现现代“物证”的司法证明中发挥了巨大的作用。科学技术能客观、及时地提供科学证据,在未来的司法活动中将大显身手。     

非法证据排除中的“实质说理”与改革建议

关于非法证据排除规则,我国2012年《刑事诉讼法》确立了“非法言词与实物区别排除”,或者说,“强制排除与裁量排除相结合”的模式。当前,非法证据排除说理是整个刑事裁判文书说理的一个“短板”。在司法实践中,许多瑕疵证据、非法证据通过“补正”、“合理解释”被采纳,但缺乏“实质说理”。强化以审判为中心的诉讼制度改革,需要强化非法证据排除的“实质说理”。这一完善过程是艰巨的,涉及实体规则、程序规则、配套制度等方面的综合改革。从长远来看,有必要建构一独立自洽的针对证据合法性调查的“诉中诉”程序。
