A New Method for Human ABO Genotyping Using a Universal Reporter Primer System

Abstract: We developed a new method for forensic ABO genotyping based on a universal reporter primer (URP) system. This allows for the simultaneous detection of six single nucleotide polymorphism (SNP) sites in the ABO gene (nucleotide positions 261, 297, 526, 703, 796, and 803). This URP system provides obvious peaks, ranging from 82 to 151 bp in length. ABO genotypes were classified and successfully genotyped by our method, including minor alleles that may cause a discrepancy between the genetic data and serological phenotypes. Full profiles were identified using as little as 0.1 ng (0.05 ng/reaction) of standard K562 and 9947A DNA. Moreover, the success rate of genotyping from a URP system was much higher than that from a conventional primer extension method in degraded DNA. This method enables simple and rapid detection of multiple SNP sites on human ABO genes and is highly specific and sensitive when using limited and degraded DNA.

The exploitation of Business Register data from a public sector information and data protection perspective: A case study

Business Registers (BRs) are a very important information resource for investors, creditors, financial institutions and public authorities. The possibility to aggregate and interconnect these data at a European level could enhance the transparency of companies towards those actors and add a great deal of value to the raw Business Register data. The European BRITE project intended to provide adequate tools to meet these demands. BRITE will provide easier access and cross-border interoperability of Business Register data throughout Europe. On the other hand, the processing of BR data within the BRs and BRITE triggers several important European legislations such as the Data Protection Directive and the Directive on the re-use of public sector information. In this paper, the processing of BR data will be analysed from the perspective of both data protection and public sector information laws, analysing as well the relation between both regulations. Do these regulations strike an optimal balance between the interests of private data vendors to re-use BR data and enhance business transparency and the need to protect the personal data of natural persons?     

Profiling the mobile customer – Privacy concerns when behavioural advertisers target mobile phones – Part I

Mobile customers are being tracked and profiled by behavioural advertisers to be able to send them personalized advertising. This process involves data mining consumer databases containing personally-identifying or anonymous data and it raises a host of important privacy concerns. This article, the first in a two part series on consumer information privacy issues on Profiling the Mobile Customer, addresses the questions: “What is profiling in the context of behavioural advertising?” and “How will consumer profiling impact the privacy of mobile customers?” The article examines the EU and U.S. regulatory frameworks for protecting privacy and personal data in regards to profiling by behavioural advertisers that targets mobile customers. It identifies potential harms to privacy and personal data related to profiling for behavioural advertising. It evaluates the extent to which the existing regulatory frameworks in the EU and the U.S. provide an adequate level of privacy protection and identifies key privacy gaps that the behavioural advertising industry and regulators will need to address to adequately protect mobile consumers from profiling by marketers. The upcoming second article in this series will discuss whether industry self-regulation or privacy-enhancing technologies will be adequate to address these privacy gaps and makes suggestions for principles to guide this process.¹

An initial evaluation of stable isotopic characterisation of post-blast plastic debris from improvised explosive devices

A number of two-way radios, similar to those which have been employed to initiate Improvised Explosive Devices (IEDs), were acquired from a commercial supplier and grouped into four pairs. Samples of plastic material were collected from five distinct regions of each radio and analysed by Infrared and Raman spectroscopy to identify the nature of the material. One radio of each pair was then subjected to detonation with a commercially available plastic explosive. The combination of radio and explosive was considered to be representative of the components of an IED. Following detonation, fragments were recovered and, where possible, identified as specific sampling points of the radio.A combination of δ²H and δ¹³C stable isotopic analysis of material from each of the five sampling points was found to provide a pattern which was characteristic of a given radio and provided a means to associate pairs of radios. When few fragments were recovered, no positive association could be made between the fragments and the paired, undamaged radio. This was attributed, in part, to manufacturing variation in the radios. However, when three or more post-blast fragments were recovered it was possible to associate these with the paired, undamaged radio with a high degree of certainty.     

Testing a promising homicide reduction strategy: re-assessing the impact of the Indianapolis “pulling levers” intervention

Since the publication of analyses suggesting the significant impact on youth homicide of the Boston “pulling levers” intervention, a series of studies of similar strategies have indicated promise in reducing homicide and gun assaults. One of these studies was an assessment of a pulling levers strategy in Indianapolis, where trend analyses indicated a significant reduction in homicide following the intervention, while six other similar Midwestern cities did not experience a significant decline in homicide. We re-assess the results of the Indianapolis study by disaggregating the offenses into gang- and non-gang homicides. Given that the pulling levers program focused on influencing gangs and networks of chronic offenders, the impact of the intervention should be more apparent for gang homicides than for non-gang homicides. Alternatively, should the impact be similar for non-gang homicides, then it is more likely that the downward trend would be caused by unmeasured external forces. Coefficient-difference tests relying on estimates obtained from autoregressive integrated moving average (ARIMA) time–series models indicate that gang homicides declined significantly more than did non-gang homicides following the Indianapolis intervention. These findings suggest ‘something happened’ to gang homicides that did not happen to non-gang homicides, which adds further support that the pulling levers initiative was the driving force behind the overall reduction in homicide in Indianapolis.
