X-ray mapping technique: a preliminary study in discriminating gunshot residue particles from aggregates of environmental occupational origin

The possibility of detection of lead-antimony-barium aggregates from non-firearm sources is confirmed according to the tests performed on brake pads, and firework and automobile workers. Moreover, information on particles taken from cartridge cases shows the relative feeble importance of the morphology in distinguishing gunshot residues (GSRs). Furthermore, also the presence in the spectrum of other elements (e.g., iron) is not so conclusive. In this panorama, the possibility of discriminating gunshot residue particles from other non-firearm lead-antimony-barium aggregates is investigated: the proposed method is based on X-ray mapping technique--currently applied used in Reparto Carabinieri Investigazioni Scientifiche in Rome, the forensic service of Italian Carabinieri--according to which the spatial distribution of the emission energy of each element of the sample is pictured. Gunshot residues present the same lead-antimony-barium distribution (or at least the same antimony-barium distribution with lead nodules), as some other environmental occupational aggregates do not (different plaques of lead, antimony, and barium). So, X-ray mapping technique can offer a new fundamental evaluation parameter in analysis of gunshot residues with scanning electron microscopy/energy-dispersive (SEM/EDS) spectrometry, and new standards could be considered.     

Y-chromosomal STR haplotypes in an Albanian population sample

Eight Y-chromosomal short tandem repeats (STRs), DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393 and DYS385, were typed in a population sample (n=101) of first-generation Albanian immigrants living in Italy.     

Anti-money laundering by international institutions: a preliminary assessment

This paper presents an evaluation of the Anti-Money Laundering and Combating Financing of Terrorism (AML/CFT) program. It briefly discusses why this can be seen as the birth of a “regime for financial integrity”. We find that some areas of the AML/CFT framework are consistently weaker than others in the area of prevention measures. Specifically, we have two findings: the first, positive one, points to a substantial adequacy of the repressive measures; the second, negative one, points to a substantial failure of countries to adopt adequate preventive measures, and calls for renewed efforts to improve implementation of preventive measures across the board, with specific regard to the activity of financial sector regulatory and supervisory authorities. Also, Eurozone countries outperform all other groups in the sample. Finally, the limited availability of country information and the multiplicity of assessors and methodologies make it difficult to evaluate the performance of the program. Therefore, we suggest greater transparency and availability of detailed countries’ information, and follow up assessments of the weak areas of a country’s AML/CFT framework at higher frequency than the established 5 years.

The Battle of the Forms—There Is a Purpose

This article provides an alternative approach to the daunting task of teaching business undergraduates a fundamental appreciation of the flexibility of the Uniform Commercial Code (UCC) and the ability of the UCC to adapt to the needs of commerce by facilitating fair, efficient transactions. Paradoxically, we suggest using one of the most difficult sections of the UCC, Section 2-207, the often discussed "Battle of the Forms," to make UCC concepts and the relationships of those concepts to modern business transactions easier to understand. This alternative approach is also designed to help students appreciate the challenges of establishing rules to assure fair and efficient transactions and how changes in the way transactions occur impact the laws and how the laws impact the changes. This article also presents exercises, questions, and illustrative flowcharts used successfully over several years in undergraduate business law classes. These tools produce an integrated method for presenting UCC Section 2-207. While no sane individual has ever professed a love for UCC study, students and faculty have expressed tolerance and a palpable appreciation for these methods.     

European citizenship and political identity

A common European identity is necessary to support European citizenship. National identity does not represent a suitable model for European identity because it relies on elements of kinship, like ancestry, culture, language and traditions, which are not shared by all European citizens at the same time. Only a model of collective identity based on political association could bring together all the different European cultural and national identities. However, if we reject the national, culturally homogeneous model of identity in favour of an entirely political one, we are faced with the task of defining the substance of European political identity. The main purpose of this paper is to outline the essential elements of a European political identity, by looking at Europe's political and constitutional history and at the practice of citizenship in the European Union. European political identity and citizenship will be confronted with two major issues affecting the fields of identity and citizenship: pluralism and exclusion.     

Reference Points and Democratic Backsliding

We propose a theory of democratic backsliding where citizens' retrospective assessment of an incumbent politician depends on expectations that are endogenous to the incumbent's behaviour. We show that democratic backsliding can occur even when most citizens and most politicians intrinsically value democracy. By challenging norms of democracy, an incumbent can lower citizens' expectations; by not doubling down on this challenge, he can then beat this lowered standard. As a result, gradual backsliding can actually enhance an incumbent's popular support not despite but because of citizens' opposition to backsliding. This mechanism can only arise when citizens are uncertain enough about incumbents' preferences (e.g. owing to programmatically weak parties). Mass polarization, instead, can reduce the occurrence of backsliding while simultaneously increasing its severity.
