Morphometric Investigation of Death by Asphyxia

Abstract:  The aim of this study was to investigate the possibility of distinguishing deaths by asphyxia from those due to natural causes by comparing morphometric measurements in lungs. The study population comprised 27 subjects: 14 cases of death by asphyxia (hanging or drowning) and 13 cases of sudden natural death. Eighty parenchyma sections were used for each subject. Data were collected by computerized image analysis. Measurements aimed at quantifying, as percentages, pulmonary parenchyma (mean values of positive-fraction areas [PFA] and their standard deviations). Subjects who died of natural causes and of drowning showed a relative internal homogeneity compared to those who hanged. Results show significant discrimination between drowned subjects and those dying of natural causes (mean of PFA p  = 0.01) and between hanged and drowned subjects (SD of PFA p  = 0.04). Attention must be paid to the possible role played by senile emphysema. The method is proposed as a complementary tool in forensic cases.     

Korruptionsstrafrecht und Dienstrecht

Mit dem am 1. September 2009 in Kraft getretenen Korruptionsstrafrechts?nderungsG 2009 wurden die Tatbest?nde des StGB zur Korruptionsbek?mpfung neuerlich ge?ndert. Die Vorl?uferregelung war in Wissenschaft und Praxis auf heftige Kritik gesto?en. Abgesehen von zahlreichen Unklarheiten hatte sie für ?ffentliche Bedienstete so strenge Regelungen geschaffen, dass sogar bisher erlaubte Verhaltensweisen kriminalisiert waren: insb die sog "orts- und landesüblichen Aufmerksamkeiten" und die Teilnahme an Repr?sentationsveranstaltungen. Demgegenüber trachtet die neue Regelung nun sorgf?ltig, Wertungswidersprüche im Verh?ltnis zum Dienstrecht zu vermeiden. Dazu wurde eine Verweistechnik gew?hlt: Einige der neuen Tatbest?nde verweisen nun geradezu pauschal auf die dienstrechtlichen Verbote und ausnahmsweise bestehenden Erlaubnisse. Um zu wissen, was strafbar ist, muss man also nun die Regelungen des Dienstrechts kennen. Der folgende Beitrag schildert die wichtigsten Probleme, die sich aus dieser Anknüpfung ergeben, und untersucht die Verfassungskonformit?t der neuen Regelungen.     

What Kinds of Trade Liberalization Agreements Do People in Developing Countries Want?

One of the most striking developments in the global economy in the past decades is the rapid proliferation of preferential trade agreements (PTAs), with many of them concluded among or with participation of developing countries. On the presumption that current popular debates on trade policy are not so much about whether citizens want free trade but rather what kinds of trade liberalization they want, we examine individual trade policy preferences with regard to PTAs that can vary in content along several dimensions. To that end we carried out conjoint choice experiments embedded in representative surveys in three developing countries that differ strongly in income levels, political system, and trade liberalization history: Costa Rica, Nicaragua, and Vietnam. We conceptualize trade policy preferences as preferences over the scale and scope of trade liberalization, environmental and labor standards, and labor market access (migration). Two main findings emerge. First, non-economic considerations, such as sympathy/antipathy toward particular countries and environmental and labor rights concerns influence citizens’ preferences at least as much as factors based on standard economic logic. Second, preferences over particular facets (attributes) of trade liberalization, that is PTA content, are surprisingly consistent across countries, despite strong differences in macro-economic and political context.     

Italy’s Migration Policies Combating Irregular Immigration: from the Early Days to the Present Times

Italian migration policies combating irregular immigration from the early 20^th century to the present times have been increasingly debated and controversial. Four phases are detectable: the absence of a legal framework while Italy was still an emigration country, the first regulations of the 1980s, policies influenced by both the European integration process and the increase in immigration until 2002 and, lastly, the country’s controversial approaches since 2004. What is noticeable is a dichotomy in Italy’s migration policies, with generally consistent internal measures and often contrasting external ones.     

Women and Men who Committed Murder: Male/Female Psychopathic Homicides

The present study was designed to compare gender differences in psychiatric diagnosis with the dimension of psychopathy in women and men who had attempted or committed homicide. The study samples consisted of 39 homicidal females and 48 homicidal males who were confined in one of Italy’s REMS or prison facilities in two southern provinces of Italy (Puglia and Basilicata). Assessment instruments included the SCID-5, the PID-5 IRF, and the PCL-R. Each gender group was stratified according to the level of criminal responsibility for the homicidal offense (full, partial, absent), and after assessments, according to the degree of the psychopathic dimension. There were clear gender differences in homicidal individuals. Female offenders were less likely to have had a record of criminal charges/convictions or imprisonment, and their homicides were more often intrafamilial, victimizing especially of their children, whereas males targeted intimate partners and extrafamilial victims. In the entire group, there was an inverse relationship between the level of psychopathy and the personality disorder on one side, and the psychotic disturbance on the other. Factor 2 (lifestyle/antisocial dimension) of the PCL-R was higher among the homicidal males, whereas females tended to score higher on Factor 1 (the interpersonal/affective dimension). Finally, if the psychopathic dimension is a qualifier for antisocial personality disorder, as indicated in DSM-5, this appears to be less true for females who tend to have other personality disorders.     

Artifacts Caused by Leaf-Cutting Ants of the Genus Atta (Hymenoptera: Formicidae): Postmortem Bite Injuries and the Tearing of Clothes

Ants are one of the first insects to find an exposed cadaver and can be present during all stages of decomposition. Although these organisms are not commonly used in postmortem interval estimates, they are to be taken into account on criminal investigations involving human corpses, since they can leave bite marks that can be mistaken for antemortem or perimortem injuries, which could be misleading when ascertaining the occurrence of abuse or physical altercation during a crime. A few studies report the action of ants on human cadavers and even though leaf-cutting ants of the genus Atta are frequently encountered in succession studies that use animal carcasses, there are no records of these fungus-growing species on human corpses. Atta is a genus restricted to the New World, ranging from northern Argentina to southern United States and acts as one of the most conspicuous neotropical herbivores. In this study, we report three cases of violent death that illustrate the impact of ants, especially those of the genus Atta, in a forensic setting. We compare the patterns displayed by postmortem bite injuries caused by leaf-cutter ants and other common species with less robust mandibles. We also present the capability of Atta ants to create artifacts by cutting victim’s clothes in a crime scene, contributing to the knowledge of ant-mediated confounding factors in crime scene investigation.     

Inter-parliamentary European Union–Latin American Caribbean (EU-LAC) relations and the increasing political convergence among Latin American regional parliaments (2006–15)

Europe and Latin America present a long-standing tradition of parliamentary diplomacy and particularly in the development of regional parliaments. Since the 1970s, inter-parliamentary relations between the two regions have been institutionalized, first by the regular dialogue of the European Parliament with the Latin American Parliament (Parlatino) and more recently, in 2006, with the creation of the Euro-Latin American Parliamentary Assembly (EuroLat). Apart from representatives of Parlatino, EuroLat includes in the European Union-Latin American Caribbean (EU-LAC) parliamentary dialogue members of other regional assemblies created in recent decades, such as the Andean Parliament, the Central American Parliament and the Mercosur Parliament. However, recent EuroLat meetings have made evident a polarization of positions on regional politics between European and Latin American sides, especially regarding the political and human rights situation in Venezuela. In this sense, the present paper analyzes the impact of EU-LAC relations on the political convergence of Latin American parliaments concerning regional political issues. The aim is to discuss how institutionalized relations with the European Parliament, through EuroLat, increased convergence among Latin American parliamentarians. This argument is exemplified by the joint defensive position on the Venezuelan political situation adopted by Latin American parliamentarians vis-à-vis the European Parliament's condemnatory position.     

Intersektionalit?t als Beitrag zu einer gesellschaftstheoretisch informierten Ungleichheitsforschung

The following article argues that an in depth analysis of different living conditions requires a theoretical and empirical perspective which does not only take into account class but also other categories of social inequality such as gender, race and body. Departing from the idea that these categories are mutually intertwined, the article suggests an intersectional multi-layered approach which allows to examine reciprocal effects between class, gender, race and body on three different levels: the level of social structures, the level of identity construction and the level of symbolic representation. Considering the theoretical relationship between the analysis of class and social inequality, the article also intends to understand and explain how these different levels of analysis are interrelated, how the linkage between social categories and levels of social reality have to be methodologically reflected and how they can be made accessible in and through empirical research.     

DNA internal standard for the quantitative determination of hallucinogenic plants in plant mixtures

Here, we show a new, simple, and rapid SYBR Green-based Real-Time PCR assay for the quantification of hallucinogenic plants in plant mixtures. As a test plant, Salvia divinorum Epling & Játiva-M., a perennial herb belonging to the Lamiaceae family able to induce hallucinations, changes in perception, or other psychologically induced changes with similar potency as LSD, was used. The method was tested on seven mixtures 100/0%, 80/20%, 60/40%, 40/60%, 20/80%, 10/90%, 0/100% (w/w) S. divinorum versus a non-hallucinogenic plant, Salvia officinalis. Total DNA was extracted from samples and quantified by Real-Time PCR. Arabidopsis thaliana genomic DNA was added, as internal standard, at the beginning of each extraction. A new formula for the interpretation of Real-Time PCR data, based on the relative quantification of DNA extracted from mixture versus a reference DNA extracted from a known amount of pure S. divinorum, was developed. The results of this work show an almost perfect correspondence between Real-Time PCR-calculated weight and the weight estimated by an analytical weighted method, proving the effectiveness of this method for the quantitative analysis of a given species in a plant mixture.
