Computational Approach to Identify Different Injuries by Firearms

Complications arise in the analysis of gunshot wounds to the maxillofacial region, when neither the projectile nor the gun is found at the crime scene. We simulated 5‐ and 15‐cm firing distances at a human mandible to investigate the external morphology of entrance wounds based on fire range. The ammunition models, .40‐caliber S&W, .380‐caliber, and 9 × 19‐mm Luger, were constructed with free‐form NURBS surfaces. In a dynamic simulation, projectiles were fired against mandibular body 3D model at 5 and 15 cm. All entrance wounds presented oval aspect. Maximum diameter and von Mises stress values were 16.5 mm and 50.8 MPa, both for .40‐caliber S&W fired at 5 cm. The maximum energy loss was 138.4 J for .40 S&W fired at 15 cm. In conclusion, the mandible was most affected by .40‐caliber S&W and morphological differences were observable in holes caused by different incoming projectile calibers fired at different distances.     

Magazine Influence on Cartridge Case Ejection Patterns with Glock Pistols

In this study, the cartridge case ejection patterns of six different Glock model pistols (one specimen per model) were compared under three conditions: firing with a loaded magazine, an empty magazine, and without magazine. The distances, covered by the ejected cartridge cases given these three conditions, were compared for each of the six models. A significant difference was found between the groups of data for each of the tested specimens. This indicates that it is important that, to reconstruct a shooting scene incident based on the ejection patterns of a pistol, test shots are fired with the same pistol type and under the correct magazine condition.     

On the Origins of the Franco-German EMU Controversies

EMU represented an important change in the economic constitution of the European Union. It is, to a large extent, a culmination of a process of Franco-German reconciliation and understanding. However, in the postwar period, there were significant differences in thought and economic policy-making in Germany and France. France was dominated by the tradition républicaine, giving a central role to the state in economic life. In Germany, the federal structure of the state went together with the social market economy. In this paper an analysis is presented of these differences in thought and economic policy-making, how they evolved through time, and how they contributed to shaping the nature and economic constitution of the European Union. The focus of the paper is on the Rome Treaties, the Werner Report and the Maastricht Treaty process.     

Repeatability and reproducibility of earprint acquisition

For all forensic disciplines dealing with identification -- e.g., of glass, tool marks, fibers, faces, fingers, handwriting, speakers -- in which manual (subjective, nonautomated) processes play a role, operator dependencies are relevant. With respect to earprint identification, in the period 2002-2005, the Forensic Ear Identification research project collected a database of 1229 donors, three prints per ear, and laid down a "best practice" for print acquisition. Repeatability and reproducibility aspects of the print acquisition are tested. The study suggests that different operators may acquire prints of differing quality, with equal error rates of the matching system ranging from 9% to 19%. Moreover, it turns out that "matching" earprints are more alike when taken in a consecutive row than when taken on separate occasions. This underlines the importance of (1) studying operator effects, (2) operator training, and (3) not gathering "matching" reference material at the same occasion.     

Influence of Muzzle Instability on Bullet Deflection after Perforating Laminated Particleboards

The influence of muzzle instability on bullet deflection, when perforating laminated particleboards, was studied with three different handgun bullet types. The mean deflection angles of .32 Auto FMJ and .38 Special SJHP bullets were calculated to be 0.90° and 0.83°, respectively after perforating particleboards orthogonally at a 1 m muzzle-to-target distance. The mean angles dropped to 0.70° and 0.58° at a 15 m muzzle-to-target distance. The differences in deflection angles proved to be statistically significant (p < 0.05) with p-values of 0.023 and 0.001, respectively. The mean calculated deflection angles of .38 Special LRN bullets also dropped from 1.51° to 1.38° when the muzzle-to-target distance was increased from 1 to 15 m, but this difference was not significant (p-value of 0.357). The results support the hypothesis that muzzle instability has an influence on deflection. The possible implications for shooting incident reconstructions and for future research are discussed.     

Performance Study of a Score‐based Likelihood Ratio System for Forensic Fingermark Comparison

In this article, the performance of a score‐based likelihood ratio (LR) system for comparisons of fingerprints with fingermarks is studied. The system is based on an automated fingerprint identification system (AFIS) comparison algorithm and focuses on fingerprint comparisons where the fingermarks contain 6–11 minutiae. The hypotheses under consideration are evaluated at the level of the person, not the finger. The LRs are presented with bootstrap intervals indicating the sampling uncertainty involved. Several aspects of the performance are measured: leave‐one‐out cross‐validation is applied, and rates of misleading evidence are studied in two ways. A simulation study is performed to study the coverage of the bootstrap intervals. The results indicate that the evidential strength for same source comparisons that do not meet the Dutch twelve‐point standard may be substantial. The methods used can be generalized to measure the performance of score‐based LR systems in other fields of forensic science.     

Regulating public procurement in Brazil,India, and China: Toward the regulatory-developmental state

Since the 1990s, emerging economies such as Brazil, India, and China have adopted transparency-enhancing public procurement regulations in line with international norms. Yet they have hesitated to join the World Trade Organization's legally binding Government Procurement Agreement (GPA). Based on the Special Issue framework, this article scrutinizes the underlying domestic and international determinants, and how they influence emerging countries’ positions in two overlapping international procurement regimes. In particular, reform-oriented state actors, societal pressure, and lesson-drawing from international templates have induced a strengthening of domestic procurement institutions and turned emerging countries into “promoters” of the international transparency regime. Conversely, the rising powers have remained, to varying degrees, reluctant “spoilers” of the GPA-based market access regime in order to keep policy space and use procurement for domestic development objectives. The article suggests that this regulatory-developmental layering of rule-based governance and interventionist ambitions characterizes the variegated regulatory state in emerging countries.     

Fingermark Evidence Evaluation Based on Automated Fingerprint Identification System Matching Scores: The Effect of Different Types of Conditioning on Likelihood Ratios

In recent studies, the evidential value of the similarity of minutiae configurations of fingermarks and fingerprints, for example expressed by automated fingerprint identification systems (AFIS), is determined by likelihood ratios (LRs). The paper explores whether there is an effect on LRs if conditioning takes place on specified fingers, fingerprints, or fingermarks under competing hypotheses: In addition, an approach is explored where conditioning is asymmetric. Comparisons between fingerprints and simulated fingermarks with eight minutiae are performed to produce similarity score distributions for each type of conditioning, given a fixed AFIS matching algorithm. Both similarity scores and LRs are significantly different if the conditioning changes. Given a common‐source scenario, “LRs” resulting from asymmetric conditioning are on average higher. The difference may reach a factor of 2000. As conditioning on a suspect's finger(print) is labor‐intensive and requires a cooperating suspect, it is recommended to just condition on the number of minutiae in the fingermark.     

The Italian party system in transition: The end of polarised pluralism?

This article examines Giovanni Sartori's polarised pluralist model and its application to the Italian party system. It suggests a more appropriate alternative method for testing the model's applicability to present‐day Italy. This modification, far from changing the model of polarised pluralism, improves its empirical usefulness. The suggestion then is put forward that Italy, rather than being an example par excellence of polarised pluralism, as Sartorisees it, is neither characterised by increased polarisation nor by centrifugal competition. Instead, Italy today witnesses the prevalence of depolarisation and centripetal electoral competition.
