Diagnostic Value of PSA and AP Tests for the Detection of Spermatozoa in Postmortem Swabs from the Genital and Anal Region in Males

The aim of this study was to clarify whether positive results for prostate‐specific antigen (PSA) and acid phosphatase (AP) occur in postmortem swabs from the genito‐anal region in males (n = 80; 4 regions) and females (n = 20; 3 regions) and to calculate the positive predictive value (PPV) concerning the presence of spermatozoa. In male subjects, the highest incidence of positive test results was found in urethral swabs (PSA 76%, AP 71%) and the lowest frequencies appeared in perianal and rectal swabs (15–20%). Microscopic evaluation for spermatozoa was positive between 39% in urethral swabs and 1% in rectal swabs. PPV regarding positive identification of spermatozoa was 33.3% for PSA and 31.5% for AP. The combination of both tests yielded a PPV of 38.2%. In female cases, no spermatozoa were identified, and one case was PSA‐ and AP‐positive in perianal swabs. Our findings indicate that PSA and AP tests are of limited value for the postmortem detection of spermatozoa in male subjects.     

英美法系海上保险法保险利益原则初探

通过对英美法系海上保险法保险利益原则诞生和发展的历史的回顾,揭示了出在该原则的解释问题上逐步由“艾尔登准则”向“劳伦斯准则”靠拢的历史发展趋势。同时,通过对英国1906年《海上保险法》关于保险利益的有关条款,特别是第5条和第6条的剖析,分析了该法在关于保险利益的立法上存在着缺陷。     

论司法言谈笔录缺席的语境

司法言谈笔录文本将客观事实“转化”成语言存留时,分割了司法视角的阅读人和客观言谈语境的共时性。法律的规制和司法便利功能、记录人员选材和文字表达差异造成司法言谈笔录中某些语境的缺席。只要真正做到将事实与价值分离,其缺席语境就会自然恢复。     

浅析道路交通事故责任认定行为的性质

道路交通事故认定是在《道路交通安全法》中出现的一个法律术语,这与以往在《道路交通事故处理办法》及《道路交通安全管理条例》中出现的道路交通事故责任认定有所不同,新法中省略了"责任"二字,目的就是让人们对该行为有一个新的认识,对交通事故责任中的"责任"的应然内涵有正确的理解。     

GENDER AND ADOLESCENT RELATIONSHIP VIOLENCE: A CONTEXTUAL EXAMINATION*

A growing body of research examines the problem of adolescent dating violence. In these studies, fairly high rates of female‐to‐male violence have been documented, leading to considerable debate about the role of gender in dating and other partner violence. Drawing from a broader qualitative study of violence in the lives of African‐American youths from a distressed urban community, we weigh in on this debate by providing a contextual examination of the nature, circumstances, and meanings of adolescent dating violence. Our research shows that the meanings and consequences of girls ‘violence are strikingly different than those of boys’, and that both are grounded in gender inequalities. We conclude by discussing the significance of these findings for both feminist and general research on dating violence.     

Identification of human semenogelin in membrane strip test as an alternative method for the detection of semen

Semenogelin (Sg), a protein originating in the seminal vesicles and a substrate for prostate specific antigen (PSA or p30), is a useful marker for the identification of semen. And detection of Sg has been available commercially in a membrane test recently. PSA is commonly used to detect semen in forensic significant samples taken from sexual assault cases. The strip PSA test has been available commercially from various manufacturers for many years. In this study, we evaluated two immunochromatographic membrane tests, one for Sg and the other for PSA by analyzing human semen, other human bodily fluids/materials including urine, blood, saliva, sweat, breast milk, vaginal secretion and fecal materials, semen from various animals and forensic casework samples. The data demonstrate that both Sg and PSA strip tests provide rapid and sensitive method for identification of seminal plasma. These results show that the immunochromatographic method for Sg detection is useful for the identification of seminal plasma in forensic samples, an alternative to the method for PSA detection.     

Multiple stable isotope characterization as a forensic tool to distinguish acid scavenger samples

Acid scavengers are frequently used as stabilizer compounds in a variety of applications. When used to stabilize volatile compounds such as nerve agents, the lower volatility and higher stability of acid scavengers make them more persistent in a post-event forensic setting. Compound-specific isotope analysis of carbon, nitrogen, and hydrogen in three acid-scavenging compounds (N,N-diethylaniline, tributylamine, and triethylamine) were used as a tool for distinguishing between different samples. Combined analysis of multiple isotopes improved sample resolution, for instance differentiation between triethylamine samples improved from 80% based on carbon alone to 96% when combining with additional isotope data. The compound-specific methods developed here can be applied to instances where these compounds are not pure, such as when mixed with an agent or when found as a residue. Effective sample matching can be crucial for linking compounds at multiple event sites or linking a supply inventory to an event.     

Juvenile Court Context and Detention Decisions: Reconsidering the Role of Race,Ethnicity, and Community Characteristics in Juvenile Court Processes

The relationship between race/ethnicity, community dynamics, and juvenile court processes has long been established. Prior research has relied on city‐ or county‐level measures of community characteristics (e.g., racial composition, poverty) to examine how racial groups are processed within juvenile courts. To date, no study has utilized finer scale measures of geographic areas to examine how characteristics of juveniles’ communities impact court decisions. By utilizing official juvenile court data from a city in the southwest, this study draws upon attribution theory to examine how economic and crime community‐level measures directly and indirectly influence detention outcomes. Findings reveal that the effect of race and ethnicity in detention outcomes varies across communities, and the effect of ethnicity in detention decisions is mediated by economic community‐level measures. The theoretical and policy implications of the study findings are discussed.     

土地征收审批的正当程序改革

程序正当是土地征收理应遵循的原则,实践中的改革已使报批前的准备阶段包含正当程序要素,然而公告之前的征收审批是否也应遵循该原则却有争议。征收审批内部程序运作的技术性设置不能改变其具体行政行为的属性,而其在实质上还具有对土地权利变动进行裁决的功能。征收审批的行为属性和功能属性理论上均要求引入正当程序。现行征收审批是由申请机关单方主宰信息的封闭决策过程,这导致审批机关缺乏第三方信息对报批材料进行验证。提高审批实效的要求呼唤引入正当程序作为信息传导机制。审批机关可利用拟被征收人表达异议或抗辩的信息弥补无法观测到申请机关行为的局限,增强对报批材料的核实能力。     

A 21‐Locus Autosomal SNP Multiplex and its Application in Forensic Science

To develop a cost‐effective technique for single‐nucleotide polymorphism (SNP) genotyping and improve the efficiency to analyze degraded DNA, we have established a novel multiplex system including 21‐locus autosomal SNPs and amelogenin locus, which was based on allele‐specific amplification (ASA) and universal reporter primers (URP). The target amplicons for each of the 21 SNPs arranged from 63 base pair (bp) to 192 bp. The system was tested in 539 samples from three ethnic groups (Han, Mongolian, and Zhuang population) in China, and the total power of discrimination (TPD) and cumulative probability of exclusion (CPE) were more than 0.99999999 and 0.98, respectively. The system was further validated with forensic samples and full profiles could be achieved from degraded DNA and 63 case‐type samples. In summary, the multiplex system offers an effective technique for individual identification of forensic samples and is much more efficient in the analysis of degraded DNA compared with standard STR typing.
