The Use of Radio-Frequency Identification Tags for Labeling Dentures—Scanning Properties

Abstract:  The inclusion of radio-frequency identification (RFID)-tags within dental prostheses has been suggested as means of effectively labeling such devices and permitting rapid and reliable identification of the wearer. Previous studies have suggested that patients will accept denture labeling and recognize the need for such systems. However, they demand systems that are aesthetic, durable, and secure. One concern over the use of RFID-tags is that they could be scanned by third parties without the patient's knowledge. This study categorizes the scanning patterns of RFID-tags both in vitro and in vivo to provide data for patients for the consent process and for forensic dentists to ensure that they are scanning prostheses optimally. The results demonstrate that the RFID chips can only be read when the interrogator is in close proximity to the denture and thus should alleviate any concerns over privacy issues. However, evidence obtained from both the literature and experiments suggests that authorities must agree upon a unified standard for chip and reader specifications and protocols in order to avoid cases in which RFID-tags may fail to be read by an incompatible reader.     

Predictive Soil Provenancing (PSP): An Innovative Forensic Soil Provenance Analysis Tool

Soil is a common evidence type used in forensic and intelligence operations. Where soil composition databases are lacking or inadequate, we propose to use publicly available soil attribute rasters to reduce forensic search areas. Soil attribute rasters, which have recently become widely available at high spatial resolutions, typically three arc‐seconds (~90 m), are predictive models of the distribution of soil properties (with confidence limits) derived from data mining the inter‐relationships between these properties and several environmental covariates. Each soil attribute raster is searched for pixels that satisfy the compositional conditions of the evidentiary soil sample (target value ± confidence limits). We show through an example that the search area for an evidentiary soil sample can be reduced to <10% of the original investigation area. This Predictive Soil Provenancing (PSP) approach is a transparent, reproducible, and objective method of efficiently and effectively reducing the likely provenance area of forensic soil samples.     

Armed Struggle,Peace Process and Parliamentarism: James Connolly and the Changing Politics of Provisional Republicanism

Since 1998 Sinn Féin has moved from supporting an armed campaign to full participation in the electoral politics of Northern Ireland and the Republic of Ireland. In so doing they have had to moderate much of their rhetoric in regard to revolution and armed struggle. They have not, however, jettisoned the attachment to one of their key iconic figures, James Connolly. The retention of Connolly as a central figure in the Provisionals’ political discourse presents an opportunity to use him to examine both continuity and change in the doctrine of Ireland's most prominent republican faction.     

Digital Privacy and Article 12 of the Universal Declaration of Human Rights

This article considers the impact of digital technologies on privacy and, specifically, the issues arising from metadata. It takes the 2016 Investigatory Powers Act as an exemplar and argues, by reference to European case law, that while data arising from new technologies undoubtedly fall within the scope of privacy protections, there are questions as to the level of protection awarded. Questions arise from how the nature and intensity of intrusion is understood against a backdrop of ‘dataveillance’, as well as the underlying issue of whether ex post controls—through oversight mechanisms—are sufficient to safeguard privacy.     

China in Africa: A relationship of (Un)equals in the developing world

The unveiling of the new Southern African Customs Union (SACU) Agreement in 2002 inaugurated new democratic institutional structures for SACU. The revised SACU Agreement provides for accession by new members. Although not new, the idea of expanding SACU has gained currency in recent years. It has been suggested that enlarging SACU could overcome the ‘spaghetti bowl’ problem of overlapping regional membership of the Southern African Development Community (SADC) countries. In spite of its allure, however, enlarging SACU membership is likely to run into difficulties as negotiations about the common revenue pool and the common external tariff become bogged down by attempts to accommodate the needs and interests of countries at different levels of development. It would also spark debate about how the revenue-sharing formula should be restructured and extended to new members. Moreover, whether SACU can act as a driver of regional integration will depend on the extent to which South Africa, the regional power, can translate its hegemonic position into a leadership role.     

Capturing Finger and Palm Impressions Using a Hand Cream and Thermochromatic Paper

An inkless set of finger and palm impressions has been obtained on thermochromatic paper by incorporating the protic solvent butylene glycol into a base hand cream mixture, which is rubbed into the hands for 30 sec before donation. This requires no washing of the hands before or after donation, removing many of the difficulties associated with inked impressions. In a random trial of 50 male and 50 female participants (mean age 41 years), 96 found the hand cream pleasant and easy to use and all produced identifiable finger and palm impressions. Following donation, participants continued to rub the hand cream into their hands. Impressions were visible immediately after donation and have not exhibited fading 2 years after being taken. 10% of participants produced impressions that captured third‐level detail, the variation between participants being thought to be associated with the amount of pressure applied during donation.
