论线人侦查行为的法制化

作为一种特殊的侦查手段,利用线人侦查行为收集犯罪信息和证据在刑事案件的侦查中发挥着不可忽视的作用。考察我国现阶段有关线人侦查行为的相关规定以及在使用线人侦查过程中所出现的问题,我们不难发现对于线人侦查手段的实施和法律规制已经成为相当棘手的问题。结合域外的司法实践,只有对线人侦查手段予以法制化,才能使其更好地发挥作用,以有力地打击刑事犯罪,保障人权。

论消费信用卡透支风险的法律监管制度建设

消费信用卡给发卡行带来新的利润增长点的同时 ,也对其造成一定的风险。风险背后的深层原因是制度的缺陷。我国信用卡业务的制度缺陷主要体现在银行对持卡人拖欠透支款缺乏有效催款措施、健全的个人信用制度、信用卡担保保证制度以及完善、统一的消费信贷法规。要改变这一现状 ,促进信用卡的健康发展 ,我国应在上述几个方面加强建设步伐 ,逐步建立一个有法可依的消费信贷法律制度体系。     

警察武力使用的困惑与教学训练的反思

使用武力是人民警察自卫和打击、制服犯罪分子、犯罪嫌疑人的强制措施和保障生命安全的必要手段。然而,在警察执法实践中,思想观念陈旧,安全意识、法律程序意识乃至人权意识淡薄,违法使用武力、使用武力过当造成的伤害事例时有发生。因此,改变观念,强化法治意识,强化警务技能与战术训练,建全法律保障制度势在必行。

论信用卡恶意透支型犯罪立法科学化

恶意透支型犯罪不具有诈骗罪特征,应当将其从信用卡诈骗罪中析出,单独规定为滥用信用卡罪。对恶意透支型犯罪构成要件应予以完善。     

Detection and visualization of human tears using alternate light sources for forensic purposes

The current scientific techniques for locating body fluids focus on quick and effective methodologies for easy and reliable identification. Efficient detection and identification of body fluids play a vital role in establishing the ‘corpus delecti’ of a crime. Non-destructive techniques such as the use of Alternate Light Sources (ALS) have been exploited for crime scene searches over large areas and detection of body fluids such as blood, semen, vaginal secretions, and saliva on a range of substrates. Tears are rarely found but can be considered as potential body fluid evidence due to their unique biochemical and molecular properties. Tears are secreted in response to physical or emotional stimuli. Due to the small volume of secretions, they are often overlooked in the crime scene. Tears may be found on surfaces such as clothing, bedding, tissue, handkerchief, or balaclava. The use of ALS to locate tears on tissue paper and fabric surfaces was tested which were not apparent to the naked eye. Tears stains were successfully detected on surfaces of forensic interest with varying sample ages up to three months with a broad excitation spectrum between 254 nm and 410 nm. Dried stains on tissue paper and fabric substrates were better detected with sharp margins, clear stain pattern visibility, and fluorescence intensity in comparison with moist and fresh stains. Tears stains can hence be detected with the use of ALS and suitable filter combinations under normal conditions and do not require any specific settings to locate them. These findings are suggestive for easy and quick identification of tears on large surfaces and as a presumptive test for forensic casework evidence examination.     

我国矿地复垦存在的问题与对策

矿产资源在国民经济的发展中占有重要的地位,但是,另一方面,我们也不能忽略矿产资源在开采和利用中对环境的消极影响,尤其是对于土地的影响。在全民日益重视环境的今天,矿山复垦工作已经成为一个紧急的、刻不容缓的任务。土地复垦工作不仅关系到国土整治、环境治理,而且也是一项造福后代的系统工程,需要几代人的共同努力,需要多方的经济支持和政策扶持。目前我国土地复垦率远远落后于复垦先进的国家,诸多弊端严重制约着矿地复垦的进程,复垦工作难以开展。这就要求我们把复垦工作与其他学科紧密联合起来,吸取国外的先进经验与技术,加强国际合作,探索出一条具有我国特色的先进的矿地复垦之路。     

关于人民警察使用武器“判明”规定的思考

判明情况是法律对人民警察使用武器前作出的明确规定,但在实践中由于诸种原因,人民警察有忽视这一规定的情况。探讨判明情况的必要性、操作标准和剖析存在问题的原因,有助于逐步完善人民警察武器使用制度。     

Case study: From embedded system analysis to embedded system based investigator tools

Since mid-2012, France and Germany have had to deal with a new form of payment card skimming. This fraud consists of adding a wireless embedded system into a point-of-sale payment terminal with the fraudulent goal of collecting payment card data and personal identification numbers (PIN).This case study details the strategy adopted to conduct the digital forensic examination of these skimmers. Advanced technologies and analyses were necessary to reveal the skimmed data and provide useful information to investigators for their cross-case analysis.To go further than a typical digital forensic examination, developments based on embedded systems were made to help investigators find compromised payment terminals and identify criminals.Finally, this case study provides possible reactive and proactive new roles for forensic experts in combating payment card fraud.
