Cranial Backspatter Pattern Production Utilizing Human Cadavers

A backspatter pattern results from blood drops that travel retrograde to an applied external force. Historically, an array of animals and nonhuman objects have been used to create and study backspatter patterns. In this study, backspatter patterns captured on foam core targets that were placed 45.72 cm (18 in) behind the impact site (occipital area of the skull) were produced by cranial gunshots to human cadavers that were reinfused with fresh defibrinated bovine blood. These patterns were compared to the backspatter patterns produced by shooting blood‐soaked sponges, a typical simulant used in controlled studies of backspatter pattern production and characteristics. The backspatter pattern produced by shooting an actual human head was found to be different than those of blood‐soaked sponges in the number of stains produced, the size and size range of the stains, and the stain dispersion patterns.     

Controversial Suicide Case Using a Submachine Gun with a Sound Suppressor—The Need of Team Work of Forensic Chemistry and Firearm Examiners

Evidence materials in a presumed suicide case were studied by a firearm examiner and a forensic chemist. The victim's body with double gunshot wounding in his forehead, a machine gun in the sustained fire mode with a silencer, and four cartridge cases were found. Examinations of the evidence, the case file studies, and experiments dedicated to the case were carried out. Relationships between the placement of cartridge cases and the gun were established using a fast camera. The distributions of gunshot residues on the evidence materials and within the comparative gunshot patterns were studied by means of optical and electron microscopy, X‐ray microanalysis, and infrared spectroscopy. The shooting distance was assessed to be 30 cm or more, whereas the greatest distance that could have been achieved by the victim himself was about 11–13 cm. The obtained results supported the version of homicide rather than suicide.     

Contextual information management: An example of independent-checking in the review of laboratory-based bloodstain pattern analysis

This article describes a New Zealand forensic agency's contextual information management protocol for bloodstain pattern evidence examined in the laboratory. In an effort to create a protocol that would have minimal impact on current work-flow, while still effectively removing task-irrelevant contextual information, the protocol was designed following an in-depth consultation with management and forensic staff. The resulting design was for a protocol of independent-checking (i.e. blind peer-review) where the checker's interpretation of the evidence is conducted in the absence of case information and the original examiner's notes or interpretation(s). At the conclusion of a ten-case trial period, there was widespread agreement that the protocol had minimal impact on the number of people required, the cost, or the time to complete an item examination. The agency is now looking to adopt the protocol into standard operating procedures and in some cases the protocol has been extended to cover other laboratory-based examinations (e.g. fabric damage, shoeprint examination, and physical fits). The protocol developed during this trial provides a useful example for agencies seeking to adopt contextual information management into their workflow.

Social structure of the Jewish quarter in Vienna during the liberal era (1850–1900)

The article examines the nature of residential and coresidential patterns in the second half of the 19th century in a district of Vienna known as Leopoldstadt, which had a large Jewish population. Analysis of a database from this district, paying attention to occupation and class variables, suggests that the Jewish population therein was more mixed than traditional interpretations suggest, and that the concentration of Jews there can plausibly be explained mainly by reference to residential choices made by Jews to live near an economic infrastructure that catered to their religious and cultural needs. The patterns identified in the data suggest further that in interpreting the residential patterns of the city it is necessary to conceptualize the problem as one of interaction between religion, economics, and residential choice.     

Frequency,timing and intensity of remarriage in 19th century Flanders

The article addresses the belief that the Early Modern period and the early 19th century were characterized by “many” remarriages. The confusion in the analysis, however, between proportion and intensity has led much research down the wrong track. The evolution in remarriage intensity and in some other sociodemographic remarriage characteristics was measured for the period 1800–1913 in Leuven, Aalst, and Bierbeek—three areas with different socioeconomic structures and cultural climates. Comparison of the age-specific ratios shows that the remarriage probability of widowed people was often lower than first-marriage probability of those not previously married, even in the first half of the 19th century. In so far as our data are representative of the Early Modern period, the claim that “many” remarriages took place then must be put into perspective. In fact—with the exception of young widowers—fewer remarriages than first marriages often occurred. The proportion of remarriages fell from 20–25% in the first half of the 19th century to 10–15% by the end of the century. The most frequently occurring remarriage type was that between a widower and an unmarried woman; the least common was between a widower and a widow. An additional cultural factor was that from approximately the mid-19th century on, first marriage was so central to the development of a private social environment and was so highly valued that a watered-down version, in the form of remarriage, was held in low esteem and even rejected.     

中越贸易人民币结算模式问题研究

目前,“地摊银行”结算占据中越边境贸易结算的主导地位,而一般贸易结算很大程度上还需要借助美元来完成整个操作流程。本文基于结算模式视角,具体探析中越贸易结算状况,提出“现行结算模式不是标准化的模式”这一观点。结合近年推出的人民币跨境贸易结算进程,从短期看,可以考虑建立中越货币自由兑换试验区;从中长期看,需要建立统一、高效的中越双边清算体系,进一步提升人民币的竞争力并逐步实行人民币自由兑换,从而推进人民币在东盟的区域化。     

Enhancing the Visibility of Injuries with Narrow‐Banded Beams of Light within the Visible Light Spectrum

The use of narrow‐banded visible light sources in improving the visibility of injuries has been hardly investigated, and studies examining the extent of this improvement are lacking. In this study, narrow‐banded beams of light within the visible light spectrum were used to explore their ability in improving the visibility of external injuries. The beams of light were induced by four crime‐lites^® providing narrow‐banded beams of light between 400 and 550 nm. The visibility of the injuries was assessed through specific long‐pass filters supplied with the set of crime‐lites^®. Forty‐three percent of the examined injuries improved in visibility by using the narrow‐banded visible light. In addition, injuries were visualized that were not visible or just barely visible to the naked eye. The improvements in visibility were particularly marked with the use of crime‐lites^® “violet” and “blue” covering the spectrum between 400–430 and 430–470 nm. The simple noninvasive method showed a great potential contribution in injury examination.
