The use of bacteriological analysis of the blood in the diagnosis of death by drowning

Investigation of blood samples from the femoral vein of subjects drowned in water and died of other causes (control) was carried out. Penetration of microflora contained in water into the bloodflow of the drowned people was shown. Possibility of using bacteriologic analysis of the postmortal blood to diagnose death from drowning was stated. Ps. putida and Ps. fluorescens. that were not present in the blood of persons who had died of causes other than drowning were recommended as test bacteria. Selective media and methods to isolate the bacteria from the cadaveric blood were chosen.     

试论“命案必破”防误体系的构建

有些人误认为公安部提出“命案必破”就是强调破案率，就是承诺100％的破案，就是宁可错究也不可错放，结果急功近利、造成冤假错案，从而对“命案必破”提出了质疑和否定。究其原因，主要是对“命案必破”理解把握不准所致，只有正确把握和应用好“命案必破”这把“双刃剑”，才能发挥和挖掘其应有的最大价值。     

Specimen preparation for ABO determination of various kinds of blood stains

Trying to optimize the preparation of blood stains, we found methanol fixation not to produce very good results for the determination of ABO blood group antigens. It is advantageous to transfer blood stains before testing to cotton cloth. This transfer is also of practical use if blood stains are to be saved on a smooth surface for lateral determination. We testet on 35 different carrier materials, on which blood stains in casework often were found, whether blood grouping gave better results on either the original material or after transfer. Results are shown on a table. The test revealed, that solubility of the stain in aqua dest is a good sign for a successful transfer. Blood stains on pine-wood soil, soil and loam were not suited for ABO grouping.     

From Interactional Justice to Citizenship Behaviors: Role Enlargement or Role Discretion?

An organizational field study examined the mechanisms through which supervisors’ interactional justice influences employees’ individual-directed organizational citizenship behaviors (OCBs). Although, previous research supports the relationship between interactional fairness and OCBs, the mechanisms of operation remain unclear. Separate frameworks, based on role enlargement and role discretion exist, with no prior attempts to compare them. In this study, I examine two competitive models, (a) a role enlargement model, using employees’ role definitions as a mediator and (b) a role discretion model, using employees’ role definitions as a moderator. The results, based on data collected from 141 employee-manager dyads in a work organization, confirm that role definitions moderate the relationships between interactional justice and OCBs. The findings are discussed to derive theoretical and practical implications and directions for future research.     

The cost price of expertise as an objective index of the work-share coefficient of the forensic medical expert]

The author suggests a method for estimating the net cost of a forensic medical expert investigation, consisting in calculation of an objective real coefficient of the ratio of various expert investigations to the reference value. The ratio between forensic medical investigation budget and the total number of these investigations forms the basis for the estimation of the net cost of an expert evaluation.     

转型时期中国政治资源的充分开发

转型时期,中国政治资源的开发受影响政治资源总量的多种因素制约。而这一时期,政治资源严重流失的现状,使其充分开发显得尤为紧迫。转型时期,中国政治资源的充分开发主要通过两种途径来实现。一是对中国政治资源利用经验的总结分析,二是对国外政治资源利用经验的借鉴。     

Report of a European collaborative exercise comparing DNA typing results using a single locus VNTR probe

A collaborative exercise was carried out in 1989 among 12 European forensic laboratories using the single locus VNTR probe pYNH24, the restriction enzyme HinfI, the same set of human genomic DNA samples, and a standardized DNA size marker. The objectives of the exercise were: (1) to study the degree of variation within and between laboratories, (2) to obtain information on requirements for technical standardization allowing the exchange of typing results and (3) to compare different approaches for the identification of allelic DNA fragments of unknown size. Each laboratory carried out up to 10 independent typing experiments using the same DNA samples. The results were analysed independently by two laboratories using three different methods. The results of the exercise demonstrate the correlation of typing that can be achieved within and between laboratories under conditions of minimal standardization.
