Comparison of enzyme assay and radioimmunoassay for the measurement of human acid phosphatase in cases of sexual assault

We investigated whether a radioimmunoassay for prostatic acid phosphatase might be used as a more specific test for the identification of semen in samples from cases of sexual assault than the measurement of total acid phosphatase enzyme activity. The results of the measurement of acid phosphatase by enzyme assay in semen and vaginal swab extracts were compared with the results of the radioimmunoassay. It was found that the radioimmunoassay is a sensitive and more specific method than the enzymic determination of acid phosphatase. Incidentally we have found that a low concentration of an immunological cross reacting acid phosphatase is present in semen free vaginal swab extracts.     

德尔菲法在构建政府绩效指标体系中的应用——以乡镇政府为例

评价指标是政府绩效评价的关键要素。咨询专家的选择、初始指标集的确定和咨询问卷的拟订以及进行多轮征询和数据处理是应用德尔菲法构建政府绩效指标体系过程中的关键环节。应用德尔菲法构建政府绩效评价指标体系的一般方法,如以乡镇政府为例,选取50位专家进行三轮征询,获得由37个指标构成的乡镇政府绩效评价指标体系,对中国政府绩效评价(或类似于绩效评价)活动具有参考意义。

Overcoming Barriers to Mediation in Intake Calls to Services: Research‐Based Strategies for Mediators

In this article, I investigate intake calls to community mediation services in which disputing neighbors ask mediators to help them resolve their conflicts. These calls are the first point of contact between potential clients and mediators. To maintain their organization's funding, mediators must convert a sufficient number of these callers into clients of the service. Intake calls, however, are not treated as part of the mediation process proper, and mediators are not trained to handle them. I audio‐recorded and transcribed approximately two hundred calls to mediation services based in the United Kingdom and then analyzed them using conversation analysis. I identified several factors routinely present in these intake calls that seemed to prevent disputants from ultimately engaging in the mediation process; I characterize these factors as “barriers to mediation.” These barriers include callers' lack of knowledge about mediation as a service and mediators' often ineffective methods of explaining the process. In particular, callers rejected mediation services when the mediators explained that mediation is an impartial service. Some of the mediators, however, managed intake calls differently, describing it more effectively, expressing empathy or affiliation with callers, and thus were able to overcome many of the callers' most common concerns about the process. In this article, I also discuss this study's implications for understanding the institution of mediation and for training mediators.

Lipidic compounds found in soils surrounding human decomposing bodies and its use in forensic investigations – A narrative review

Following decomposition of a human body, a variety of decomposition products, such as lipids, are released into the surrounding environment, e.g. soils. The long-lasting preservation in soils and their high diagnostic potential have been neglected in forensic research. Furthermore, little is known about the preservation, chemical transformation, or degradation of those human derived lipids in soils. To date, several studies identified various lipids such as long-chain free fatty acids and steroids in soils that contained decomposition fluids. Those lipids are preserved in soils over time and could serve as markers of human decomposition in forensic investigations, e.g. for estimating the post-mortem interval or identifying the burial location of a human body. Therefore, this review focuses on the current literature regarding fatty acid and steroid that have been detected in soils and associated with human body decomposition. After a short introduction about human decomposition processes, this review summarises fatty acid and steroid analysis applied in current case studies and studies related to taphonomic research. This review provides an overview of the available studies that have used fatty acids and steroids as identifiers of human decomposition fluid in soils in a forensic context and discusses the potential for developing this innovative field of research with direct application in a forensic context.
