外伤后阴茎勃起功能障碍的夜间阴茎勃起功能监测

目的 夜间阴茎勃起功能监测(NPT)技术在阴茎勃起功能障碍程度鉴定中的法医学意义。方法 用RIGISCAN PLIJS SYSTEM,对13例外伤后主诉阴茎勃起障碍的被鉴定人进行监测。结果 NPT检查的13例被鉴定人,阴茎勃起功能正常者3例,轻度减退者5例,中度减退者2例,完全丧失者3例。其中在IIEF、自我勃起功能评价为严重功能障碍的5例中,NPT检查正常者1例,轻度减退者1例,中度减退者1例,完全丧失者2例。结论　NPT技术能够有效的确定阴茎勃起功能障碍的程度,为法医学损伤程度鉴定或伤残程度评定提供依据。     

Legal issues in oral fluid testing

The use of oral fluid for drugs of abuse testing has received increased attention with the availability of accurate methods for the collection and analysis of drugs in oral fluid specimens. Already used in the transportation and insurance industries, there is increasing interest in oral fluid drug testing in the workplace, schools, roadside driving under the influence of drugs, and criminal justice. Given that sanctions may accrue from positive test results, legal challenges are to be expected. However, with its established scientific base, demonstrated accuracy and reliability of collection and test methods, and current positive regulatory developments, it seems clear that the use of oral fluid as a specimen for drugs of abuse testing will be able to withstand judicial scrutiny.

犯罪记忆检测技术的构成

犯罪记忆检测技术包括犯罪心理生理的诱导技术、记录技术和识别技术等核心技术。诱导技术借助适宜刺激诱导被测人员产生犯罪心理生理反应 ,因此需要对测试案情进行科学分析 ,并建构有效的测试结构。记录技术将诱导产生的生理反应记录下来供测量分析。目前使用频繁的是多导仪 ,记录皮肤电反应、心动反应、呼吸反应等生理反应。识别技术通过测量、比较记录下来的生理反应来确定事件相关反应的性质 ,即是否属于犯罪心理生理反应。     

犯罪心理测试技术实案应用研究

1991年,我国研制的PGA型心理测试系统正式通过公安部审定。十多年来,犯罪心理测试技术已达到排除无辜准确率100%,知情相关、作案相关认定准确率98%,测后讯问突破的案件占受理案件的80%。犯罪心理测试技术在刑事侦查中起到了重要作用。     

Colonization of diatoms in and on porcine bone substrate and considerations of diatom ecology for forensic science

The presence of diatom algae in bone marrow has been used as forensic evidence of drowning for several decades; however, these studies are based on known or suspected recent drowning events. This study addresses the potential for diatoms to enter the bone marrow of skeletal remains, that is, de-fleshed long bones post-mortem. In laboratory and field experiments, bones were either inflicted with two access points by a cut and acid pitting or left intact. The bones were submerged in water for at least 1 week and up to 3 months. Samples of the bone surface and marrow were inspected for diatoms. The analysis considered the time required for diatoms to enter marrow and whether genus characteristics like size or mobility affect entry. The presence of an access point influenced diatom entry in that bones without an introduced access point had zero to one diatom present in the marrow, whereas a bone with an access point had >150 diatoms present in the marrow. The results of both laboratory and field phases suggest that diatoms will reliably colonize bone in as quickly as 1 week, establishing and maintaining communities for at least 3 months. However, the bone surface assemblages differ from the source community. Bone marrow displayed even more restrictive access to diatom colonization, resulting in communities dominated by small raphid diatoms. Based on these findings, we suggest some caveats on the use of diatoms as trace evidence in forensic science with recommendations for future avenues of research.

犯罪心理测试与人身识别

利用人体各种外在的或者固有的特征对人身进行识别是人类认识活动的重要组成部分,刑事侦查活动尤为如此.人类历史实践中,人身识别的方法很多.犯罪心理测试技术是科学技术发展日新月异的结果,是现代心理学、医学、生物电子学及其他学科综合应用发展的结果,依据犯罪行为人特有的犯罪心理痕迹对作案人进行人身识别,从而认定作案人,是人身识别方法在新的历史时期的拓展.
