笔迹的多层次及其在检验中的应用

在笔迹检验中,以笔迹多层次属性为基础,才能正确认识笔迹,分析笔迹,系统开展笔迹检验。文章从笔迹形成的多层次和笔迹特征的多层次两个方面系统研究笔迹内在的多层次性,探讨了多层次属性在文件物证检验中的应用,对笔迹检验理论的丰富和检验技术的提高都有着重要的意义。     

大学生思政课教学效果提升研究

在教学过程中,一名大学思政课老师应当针对教学对象特点真正把学生当作教学主体,用理论掌握学生,创新教学方式,开创第二课堂,说理透彻,以理服人,以身作则,紧扣社会热点,贴近学生实际,取得了良好的教学效果。为了进一步提升思政课的教学效果,思政课教学要树立正确的教育目的,思政课老师要着重培养学生的独立思考能力和独立人格,注重启发教育,改革考试内容和形式,加强实践环节教学。     

“切开法”快速鉴定朱墨时序

朱墨时序是指印文与字迹形成的先后顺序。"朱"代表印文,"墨"指与印文形成交叠的字迹笔画。用"切开法"进行光敏印油、印泥印文和喷墨打印字迹、激光打印字迹、复印字迹的朱墨时序鉴定实验,取得了令人满意的效果。实验证明,"切开法",所需器材简单,操作简便,准确率高,对鉴定人从业经验也没有很高要求,非常适合基层一线单位使用。     

浅析考试作弊行为的刑法规制——以上海市闵行区检察院办理的一起泄露国家秘密案件为视角

当前的司法实践中,主要以侵犯国家秘密类犯罪规制考试作弊行为,但是在"试题及答案的定密、以渎职罪名评价作弊行为、保密期限的确定、情节严重的认定、‘枪手’答案的性质"等问题上存在争议,已无法满足形势发展的需要。为了更准确、有效地依法打击考试作弊,应尽快出台考试法,并在刑法分则中单独设立"妨害考试罪",规制考试作弊行为。     

协同主义的追问与我国民事诉讼的未来

协同主义的理论来自于德国,协同主义的支持者主张,诉讼中法官和当事人应当协同发现案件事实,适用法律.同时他们认为协同主义作为一种全新的诉讼模式,是对当事人主义和职权主义的超越,我国的民事诉讼应采用这种模式.这些主张者误读了西方的民事司法改革,这种理想化的理论不仅缺乏说服力,也不符合我国的国情和实际.未来我国的民事诉讼不是走向协同主义,而是在坚持和深化辩论主义的前提下通过具体的制度完善,提升当事人的程序主体性.     

论我国司法鉴定人资格制度的完善

我国司法鉴定组织体系是在司法实践中形成的部门分设体制,在鉴定机构设置的原则、布局上呈现出多元化特点,存在司法机关内部鉴定机构、具有行政权背景的鉴定机构和面向社会服务的鉴定机构等三种类型的鉴定机构,由此导致对司法鉴定人实行职业资格与执业资格制度管理方面存在不尽完善之处。为确保司法鉴定人具有较高的业务水平、执业能力和规范执业,提高鉴定质量,有必要实行复合制的鉴定准入制度、建立健全鉴定业务的经常性培训交流与考核机制、建立法官对鉴定结论的实体审查制度和建立司法鉴定专家库等。     

唐代刑事证据制度考略

唐代是中国封建社会经济、政治和文化发展的鼎盛时期,其法律制度也达到了古代封建法制的最高水平。唐代总结其前代王朝刑事证据之经验并有所创新,直接影响着后世。唐代立法和司法实践体现了据证惟实、重视伦理权衡等证据原则,主要证据形式包括口供、证人证言、物证、书证和勘验笔录,相应的取证方法主要有取得口供和证言的刑讯、获取实物证据的现场勘验和搜查,司法官员运用经验和逻辑推理综合审查和运用证据。     

Expert examination and assessment of state under the influence of psychoactive substances

An expert examination is a medical examination performed by a doctor on the order of a police officer or investigating judge. It includes a clinical examination of the subject, collection of samples for toxicological analysis, and the doctor's assessment of whether the subject is under the influence of psychoactive substances. The doctor requires expert knowledge, skill, experience and sufficient time to successfully perform the examination. Since the accurate assessment of the effects of psychoactive substances present depends on a comprehensive evaluation of toxicological test results, the calculation of results at the time of the event and the results of the medical examination, an unprofessionally performed examination can have far-reaching consequences, primarily legal in nature.     

红外线合成图像在变造文件检验中的应用与分析

在文件检验中,黑白红外线照相是一种检验变造文件的方法,然而,在某些情况下效果欠佳。为了提高检验的准确性,不妨可以应用红外线合成图像的方法。应用Photoshop图像处理方法,根据红外线彩色照相的感光原理和色彩再现过程,对数码照相机拍摄的可见光图像和红外线图像进行适当处理,即可生成红外线合成图像。这种图像可以反映字迹对可见光和红外线的吸收与反射情况,通过判断字迹颜色有否改变来检验书写色料的异同。由此可见,利用红外线合成图像方法检验某些变造文件,可以获得黑白红外线照相无法得到的检验结果,这对提高鉴定结论的准确性具有实际应用价值。     

Age determination of ballpoint pen ink by thermal desorption and gas chromatography-mass spectrometry

Two main approaches can be used for determining the age of an ink: indirect dating and direct dating. Indirect dating is based on the chemical analysis of an ink followed by comparison with known samples in a reference collection. The collection should contain information about the inks including the market introduction dates. This approach may allow for an anachronism to be detected. The second concept is based on measuring ink components that change with age. The analysis of solvents in ballpoint inks may be a useful parameter for determining the age of ink on paper. In a previous study, the authors demonstrated that thermal desorption of ink directly from paper, followed by chemical analysis using gas chromatography-mass spectrometry (GC-MS), is a promising procedure for characterizing ink-binder resins and solvents. Preliminary tests showed that monitoring the evaporation of ink solvent from ink on paper is not a suitable method for ink dating. Thermal analysis of ink on paper in two steps revealed that fresh ink releases a relative amount of solvent at a certain low temperature in a defined period of time, which decreases as the ink ages. As a consequence, this relative amount of solvent released at a certain low temperature, and its decrease with time, can be used to estimate ink age. This age-dependent parameter was studied in 85 different inks ranging in age from 1 week to 1.5 years. It was found that some inks showed a significant decrease of this parameter up to an age of several months, and that the aging process can be monitored within this period. For other inks, however, the age-dependent parameter decreases relatively fast, e.g., within a few days, to a constant level, which can be too fast for casework. Based on these results, a general procedure for assessing the age of ballpoint pen inks on paper was developed.
