指甲花醌显现纸张上汗潜手印初步研究

目的介绍一种用天然植物提取成分指甲花醌显现渗透性纸张表面汗潜手印的方法。方法利用指甲花醌能够和手印遗留物质中的氨基酸发生显色反应来显现手印。结果显现出的手印纹线在自然光下观察呈紫褐色,并且在540nm激发光源条件下,通过红色护目镜观察还有很强的荧光特征。结论指甲花醌显现法具有安全性高、健康环保、操作简单、显现效果明显的特点。     

"找案源":司法逻辑的场景式解读

真实的司法逻辑存在于真实的司法场景中,这与理论上的短歌长吟必然有所区别。在看似悖逆司法规律的“找案源”场景中．司法机关受到经济利益、部门地位、考核要求以及体制需要等诸多动力的推动,从而呈现出除法律人判断之外的经济人、政治人、社会人等诸多逻辑形态。这些逻辑的运用构成了司法活动的复杂性。如何看待、理解并对之进行反思,将成为正确认识和改进中国司法机关行为的重要依据。     

论普选对香港特区政府的影响

即将实行的香港普选,既符合人民主权原则,也使特区政府面临中央和民众的"双重问责"。一方面,当行政决策的地方主体性被加强的同时,特区政府必须处理好与中央意志的平衡问题;另一方面,普选将推动政党、压力团体和民众的广泛政治参与,通过监督决策过程和效果,促使政务公开和透明,使特区政府更加民主和谨慎决策。     

论证据与证据提供者之间的关系——以电子证据的可信度危机为论证起点

电子证据现象反映了证据的可信度问题即所有证据形式都会被修改,所有的证据形式都面临着可信度危机。证据的可信度除了与证据的取得过程有关,还与证据提供者的可信度有关。在证据取得过程合法的情况下,证据的可信度将直接取决于证据提供者的可信度。     

Police Interviewing and Interrogation: A Self-Report Survey of Police Practices and Beliefs

By questionnaire, 631 police investigators reported on their interrogation beliefs and practices-the first such survey ever conducted. Overall, participants estimated that they were 77% accurate at truth and lie detection, that 81% of suspects waive Miranda rights, that the mean length of interrogation is 1.6 hours, and that they elicit self-incriminating statements from 68% of suspects, 4.78% from innocents. Overall, 81% felt that interrogations should be recorded. As for self-reported usage of various interrogation tactics, the most common were to physically isolate suspects, identify contradictions in suspects' accounts, establish rapport, confront suspects with evidence of their guilt, and appeal to self-interests. Results were discussed for their consistency with prior research, policy implications, and methodological shortcomings.     

Open source software (OSS) governance in the organisation

Going into the century's second decade, Open Source Software (OSS) is ubiquitous. But there remains a disconnect between OSS use and its effective management. In order to ensure that OSS is used in a way which complies with relevant licence requirements and reduces risk (for example, of adverse action from the OSS community and IP leakage through unintended application of the ‘copyleft’ terms of the GPL2); organisations should consider putting in place an effective OSS governance mechanism. OSS governance should take account of the people context, seeking to get buy-in from all stakeholder groups inside and outside the organisation. The high-level OSS strategy should then be agreed between the stakeholders, consistently with other statements of operational strategy. The next level down is the OSS policy statement, which should be clear, brief, event-driven, able to settle 80% of OSS decisions arising day to day and set out what information is to be collected and tracked. Finally, appropriate processes should be put in place to take the strain of OSS governance. Organisations should consider appointing an Open Source Compliance Officer and acquiring a software based indicator tool enabling a number of key governance processes (code review, setting agreed ‘do's and dont's’) to be automated.     

图书书名商标权保护解析

图书书名的精炼和高度概括使其难以获得《著作权法》的保护,而《商标法》保护的可行性探讨就势在必行。首先,在明确图书分类的基础上对所需要讨论的范围进行限定,并就图书书名的功能展开分析。其次,图书书名能否获得商标法意义上的保护和如何避免侵犯他人商标权属于硬币的两面,正确分析和划定二者之间的范围和界限,决定了图书书名在商标法意义上保护的可行性。最后,国外相关的立法例为图书书名商标法意义上的保护提供了反证,故适用《商标法》对其进行规制存在着难以逾越的障碍,而适用《反不正当竞争法》保护书名的可行性论证填补了这一权利保护的漏洞,并为司法实践提供了有益尝试。     

刑事照相常用紫外光源照射对DNA检验的影响研究

目的探究刑事照相常用紫外光源照射不同客体上的血指印和汗潜指印后对DNA检验产生的影响。方法分别使用254nm和365nm紫外光源在不同照射距离,不同照射时间下对不同客体表面制备的原血指印、微量血指印和汗潜指印检材进行照射,随后进行DNA定量分析。结果原血指印经紫外照射后对DNA检验结果无显著影响,微量血指印和汗潜指印经紫外照射对后续DNA检验结果认定影响较大。结论紫外光波长越短、功率越大、照射距离越短、照射时间越长,对DNA检验结果的影响越大。     

Interviewing women bereaved by homicide: assessing the impact of trauma-focused research

Abstract

The use of swearwords has hardly been investigated scientifically. Virtually nothing is known about the efficacy of swearing. The present studies set out to investigate whether the inclusion of swearwords in a testimony increases the believability of that statement. In study 1, respondents were simply asked whether they believed that using swearwords is a sign of credibility, a sign of deceit, or neither. In the second and third study, participants had to read fictitious testimonies of a suspect and a victim, respectively. Participants were exposed to testimonies with or without swearwords. The results suggested that people self-reported to find swearwords a sign of deceit (study 1), but when actually confronted with a statement, the opposite turned out to be the case (studies 2 and 3). That is, testimonies containing swearwords were perceived as more credible than swearword-free testimonies. Hence it is concluded that swearing increases believability of statements.     

Offenders' lies and truths: an evaluation of the Supreme Court of Sweden's criteria for credibility assessment

Abstract

The criteria used by Swedish courts for assessing credibility of plaintiffs' accounts were for the first time scientifically evaluated. Furthermore, unlike much previous deception detection research, we used offenders as participants instead of college students. False and truthful confessions by 30 offenders were analysed, and few significant effects were obtained. Truthful confessions were rated as having a higher degree of clarity than false confessions. Women's truthful confessions were rated as more credible than their false confessions. The offenders who were most experienced in being interviewed by the police gave a stronger impression of talking about something self-experienced in their false than in their truthful confessions; hence, it seems that offenders with more police interview experience have developed a kind of expertise in telling a convincing lie about crime. Overall, the criteria for credibility assessment used by Swedish courts had very limited usefulness in discriminating truthful and false confessions. A critique of the current status of evaluating statements in Swedish courts is provided.
