Distortion in Fingerprints: A Statistical Investigation using Shape Measurement Tools

Friction ridge impression appearance can be affected due to the type of surface touched and pressure exerted during deposition. Understanding the magnitude of alterations, regions affected, and systematic/detectable changes occurring would provide useful information. Geometric morphometric techniques were used to statistically characterize these changes. One hundred and fourteen prints were obtained from a single volunteer and impressed with heavy, normal, and light pressure on computer paper, soft gloss paper, 10‐print card stock, and retabs. Six hundred prints from 10 volunteers were rolled with heavy, normal, and light pressure on soft gloss paper and 10‐print card stock. Results indicate that while different substrates/pressure levels produced small systematic changes in fingerprints, the changes were small in magnitude: roughly the width of one ridge. There were no detectable changes in the degree of random variability of prints associated with either pressure or substrate. In conclusion, the prints transferred reliably regardless of pressure or substrate     

Identification through X-ray fluorescence analysis of dental restorative resin materials: a comprehensive study of noncremated, cremated, and processed-cremated individuals

Tooth-colored restorative materials are increasingly being placed in the practice of modern dentistry, replacing traditional materials such as amalgam. Many restorative resins have distinct elemental compositions that allow identification of brand. Not only are resins classifiable by elemental content, but they also survive extreme conditions such as cremation. This is of significance to the forensic odontologist because resin uniqueness adds another level of certainty in victim identification, especially when traditional means are exhausted. In this three-part study, unique combinations of resins were placed in six human cadavers (total 70 restorations). Simulated ante-mortem dental records were created. In a blind experiment, a portable X-ray fluorescence (XRF) unit was used to locate and identify the resin brands placed in the dentition. The technique was successful in location and brand identification of 53 of the restorations, which was sufficient to enable positive victim identification among the study group. This part of the experiment demonstrated the utility of portable XRF in detection and analysis of restorative materials for victim identification in field or morgue settings. Identification of individuals after cremation is a more difficult task, as the dentition is altered by shrinkage and fragmentation, and may not be comparable with a dental chart. Identification of processed cremains is a much greater challenge, as comminution obliterates all structural relationships. Under both circumstances, it is the nonbiological artifacts that aid in identification. Restorative resin fillings can survive these conditions, and can still be named by brand utilizing elemental analysis. In a continuation of the study, the cadavers were cremated in a cremation retort under standard mortuary conditions. XRF was again used to analyze retrieved resins and to identify the individuals based on restorative materials known to exist from dental records. The cremains were then processed and the analysis was repeated to determine whether restorative resins could be found under this extreme condition. Under both circumstances, sufficient surviving resin material was found to distinguish positively each individual in the study group. This study showed the utility of XRF as an analytical tool for forensic odontology and also the significance of the role of restorative resins in victim identification, even after cremation.     

Inquiry into the Scientific Basis for Bitemark Profiling and Arbitrary Distortion Compensation

Abstract: Prediction of dental characteristics from a bitemark (bitemark profiling) and arbitrary photographic distortion compensation are two practices proposed in bitemark analysis. Recent research on the effect of inherent skin tension properties in bitemark analysis suggests that these practices are subject to review. A biting apparatus was used to create 66 bitemarks in human cadaver skin. The bitemarks were photographed, sized 1:1, and evaluated with Adobe Photoshop^®. Metric/angular measurements and hollow volume dental overlays were employed. Distortion produced was calculated and assessed. Results showed distortional ranges were nonuniform both between bites, as well as within each bite. Thus, enlarging/decreasing the photograph uniformly would not correct the distortion that resulted. With regard to bitemark profiling, 38% of the bites created patterns that could be misleading if profiled. Features were present/absent that were inconsistent with the biter’s dentition. Conclusions indicate bitemark profiling and arbitrary distortion compensation may be inadvisable.     

Fluorescence and Structural Degradation in Composite Resins as a Function of Temperature*

Abstract: Detecting composite resin upon postmortem examination can be difficult. Ultraviolet illumination has been suggested to ease location of this material; however, this may not be advisable in incineration situations. Understanding of the chemical and physical properties of resin as a function of temperature is an important parameter in identification of this material in incineration circumstances. Twenty-seven discs of resin, Quixx (Dentsply), Filtek Supreme (3 M), and Tetric Ceram (Ivoclar) were prepared and exposed to increasing heating conditions of 200°C–900°C in 100°C increments for 30 min. Analysis was performed with Fourier transform infrared spectroscopy, ultraviolet-visible light spectrophotometry, scanning electron microscopy/energy dispersive X-ray spectroscopy, optical microscopy, and UV illumination. Characterization of the material occurred at each temperature range. The organic components and the fluorescence properties were lost at temperatures above 300°C. The inorganic component remained through 900°C. This information can aid in detection of resin in high temperature circumstances.     

The politics of post-conflict space: the mysterious case of missing graffiti in ‘post-troubles’ Northern Ireland

Why is there so little graffiti in Northern Ireland compared to cities in North America and Europe – including Great Britain, to which it is constitutionally connected, and Ireland, with which it is geographically connected? This question is particularly perplexing given the highly developed political mural tradition on both sides of the sectarian divide in the North, and the almost 15 years that have passed since the signing of the Peace Agreement ending some three decades of militarized conflict. This paper explores the connections between the absence of graffiti, and the street-level structures and processes of reconciliation or conflict – with a specific focus on the geopolitics of paramilitary control within communities throughout Northern Ireland. The contributions of the paper are three-fold: (1) it highlights the importance of graffiti as a (usually neglected) lens for assessing the degree to which the expected benefits of a peace agreement are experienced at the street level; (2) it addresses the methodological challenge of how to examine something that is not there (specifically, it studies the absence of graffiti in Northern Ireland by comparing it to the logic, mechanics and meanings of graffiti elsewhere); and (3) it questions the well-marketed representation of Northern Ireland as a unqualified case of successful post-agreement peace.     

‘Sable venus’, ‘she devil’ or ‘drudge’? British slavery and the ‘fabulous fiction’ of black women's identities,c. 1650–1838

Abstract

In this article, the author addresses the problem of how much historians can understand about the identities of individuals living in a different epoch in time, in relation to what has been termed the ‘fabulous fiction’ of black women's identities in slavery and freedom. A central argument is that stereotypes of black women were highly gendered and clustered around contradictory representations, particularly the ‘Sable Venus’, ‘She Devil’ and passive ‘drudge’. Thus, the persistence of an African-centred ‘woman's culture’ and strategies of resistance, collaboration and survival are vital to understanding black women's self-defined (as opposed to white attributed) identities. The first section examines the relationship between gender, race and culture in the mediation of African and slave women's identities. This is followed by a critical deconstruction of the ‘Sable Venus’ and interrelated black and white gendered identities in colonial slave society. The final section analyses the importance of the ‘She Devil’ in representing the resistant slave woman who defied the ‘fabulous fiction’ of white stereotyping of black women. A wide time span is adopted in order to analyse how black women's relationship to the gendered power structures underpinning colonial slavery shifted over time, as did ‘white visions’ of their identities. Unifying themes are the central location black women had in the development of colonial relations between black and white and the implications of contact at the harsh interface of African and European cultures for black women's gendered identities.
