Targeting relevant sampling areas for human biological traces: Where to sample displaced bodies for offender DNA?

Sampling strategy is one of the deciding factors in DNA typing success rates. Small amounts of bodily fluid traces and (skin) contact traces are currently not visualized in standard forensic practice. Trace recovery is usually based on the information available in a particular case and on the experience and ‘forensic common sense’ applied by the trace recovery expert. Interactions between an offender and a victim may have characteristic features, resulting in specific trace patterns. Understanding these interactions, and their resulting trace patterns, might improve crime related trace recovery as well as DNA typing success rates.In this study, we examined the interactions between offender and victim when a body has been relocated from one position/location to another. The contact between the hands of the offender and the body of the victim was visualized using a fluorescent dye in a lotion that was applied to the hands of the individual undertaking the relocation. The contact locations were scored and patterns were analyzed based on both victim and offender characteristics (height, weight, age, gender). The resulting patterns were compared to current trace recovery practices in the Netherlands. The results of this large-scale study facilitate evidence-based sampling supporting both investigative and evaluative forensic examinations.     

“重建中气”中药复方对进展期胃癌患者生存预后影响的队列研究

目的 观察“重建中气”中药复方对进展期胃癌术后及辅助化学治疗后患者生存期的影响。方法 回顾分析62例进展期胃癌患者的临床资料,根据是否服用“重建中气”中药复方将其分为中药暴露、无中药暴露两个队列。中药暴露组以“香砂六君子汤”为主方辨证加减。观察性别、年龄、首次就诊体质量和体质量指数（body mass index,BMI）、卡氏功能状态（Karnorfsky performance status,KPS）评分、复发或转移、中药暴露等因素对进展期胃癌生存期的影响。结果 对62例患者随访2年,与无中药暴露组比较,中药暴露组患者体质量和BMI显著升高（P<0.05）,复发或转移率显著降低（P<0.05）;Kaplan-Meier单因素生存分析结果显示,中药暴露、基线KPS评分、复发或转移、基线BMI是生存期的影响因素（P＜0.05）;COX多因素回归分析显示,KPS评分是总生存期的独立影响因素。结论 进展期胃癌术后患者为口服中药的优势人群,“重建中气”中药复方可增加或稳定进展期胃癌患者的体质量,提高患者生存质量,改善预后生存。     

浅谈网络环境下法律意识的价值

网络的发展对社会法治环境有很大的影响,在网络环境下,法律意识有如下价值:有助于形成网络社会的自治秩序;有利于网络法律制度的建设;为网络环境下的法治建设提供思想条件。我们应该加强网络环境下法律意识的培养。     

试析儒家德位之辨中的敬位意识

由儒家主导性开辟的德位之辨,孔子为其定下基调,孟子从道义论立场加以证明。儒家揭示德位之辨及其敬位意识,并上升到义务论性质。以德居位、敬位意识内化为责任心和忧“责”意识、义务心使然、道义论立场,对知识分子从政之路提出了责任情结问题,更使儒家的德位之辨获得了独特的理论向度和实践价值。     

The first and last signs of Main Street: semiosis and modality in California and Hong Kong Disneylands

Main Street is an indelible image in the American consciousness made hyperreal at Disneyland California in 1955. For subsequent parks in Tokyo and Paris, Disney recontextualized Main Street, but Hong Kong Disneyland’s version was formed as a copy of the California original. This copy demonstrates that transference of a structural form to a new cultural context is not a guarantee of the concomitant transmission of the originating culture’s sensory modality. The arising dissonant tension between the form (signifier) and substance (signified) of Hong Kong’s Main Street has led to its ongoing semiosis due to local cultural and corporate pressures. This paper presents a framework to analyze this dissonance and semiosis through comparison of external and internal photographs of the same eight landmarks at both parks. The problem of transferring meaning into a new cultural context for an international sign suggests Hong Kong’s Main Street could be the last that Disney constructs.     

强化九个意识,努力开创公安高校学生思想政治教育新局面

开创公安高校学生思想政治教育新局面,应找准切入点和结合点。要在思想观念上与时俱进,强化“阵地”意识、育人意识、以人为本意识、“三贴近”意识、实践教育意识、“载体”意识、养成教育意识、为人师表意识和开拓创新意识。     

Human semen stain analysis in casework sample by HRM-qPCR

Determining the biological origin of body fluid evidence from crime scenes is extremely important for criminal investigation, especially in sexual assault cases. In Brazil, sexual crimes still present low-resolution rates, where approximately 8% of cases are judged. The determination of the presence of semen in samples from crime scenes as a test prior to DNA analysis is a mandatory requirement in forensic analysis and can help to better understand the dynamics of the event. This report aims to present the methodological strategy used in a criminal case of a home invasion where a t-shirt containing visible stains similar to human semen was found at the site. Convencional tests to detect the presence of PSA and sperm cells were performed on the fabric cutouts which showed negative results. We then processed the fabric samples for genetic analysis after two-years-storage, where were performed automated method for the genetic material isolation (QIAcube, Qiagen). The Real-time PCR analysis were carried out using the SOLIScript 1-step SolisGreen (SolisBiodyne) kit, with specific primers to the TGM4 (Transglutaminase 4) gene, in the Rotor Gene Q-5Plex HRM equipment (Qiagen). The results obtained for the melt curve indicated the presence of human semen in the analyzed samples. After the HRM-qPCR assay we also analyzed the a-STR and Y-STR markers. All the results were useful for the criminal process, which led to the identification of the author of the crime.     

《公安行政法学》教学对程序意识的培育及其改进

警察执法违反程序的不规范规定容易引发群众不满意,甚至导致引发社会舆论风波的产生,损害警察形象和公安机关的执法权威。良好的公安行政实训教学体系,能够强化学员的程序法意识,为今后的执法工作规范化奠定基础。要改变当前《公安行政法学》实训教学不适应程序法意识培育的现状,既需要公安院校改善实训教学体系,也需要公安机关在实训场所和业务指导方面给与大力支持。     

论公民意识与公安执法关系

公民意识是社会意识的一个方面,对社会存在具有一定的反作用。公民意识与公安执法工作互为条件、互相促进、互相影响、互相作用。重视公民意识的培养和强化是新形势下公安执法工作创新发展的正确选择。     

论共同居住人的继续承租权

我国《合同法》第234条确定了共同居住人的继续承租权制度，然而对于共同居住人的继续承租权的性质、享受继续承租权的共同居住人的主体范围、继续承租权适用的具体对象．共同居住人行使该项权利的先后顺序等等都缺乏明确具体的规定。我国立法应该在借鉴外国先进立法的基础上加以完善，进一步明确共同居住人的主体范围．规定该权利行使的具体条件，以便更好的适用。
