Evaluation of three rapid detection methods for the forensic identification of seminal fluid in rape cases

We sought to discover whether spermatozoa concentration and the delay between ejaculation and test influence the results of seminal fluid fast detection tests. Two hundred and twenty-seven anonymous samples divided into four groups (normospermia, oligospermia, azoospermia, and controls) after a semen analysis were subjected to three fast detection semen tests: Diff-Quick fast coloration, Phosphatesmo Km Paper for acid phosphatases (AP) detection, and PSA-Check 1 for prostate specific antigen (PSA) detection. The study was performed at three time points (0, 48, and 72 h). Unlike cytology, results obtained with AP and PSA were not influenced by spermatozoa concentration. PSA detection results remained constant up to 72 h and were more reliable after 48 h than those obtained by AP detection.     

Security relations in the Black Sea region: Russia and the West after the Ukrainian crisis

The Ukrainian conflict – as all post-Soviet conflicts – has three interrelated dimensions – global, regional and local – with deep implications for international security including the Black Sea region. The strategic interdependence between Russiaand West during the last decade became not only anaemic but antagonistic. The regional implications of that can be compared to the boomerang effect: problems at the strategic level affect the regional level and return to the originators. Generally speaking, Commonwealth of Independent States conflicts can be viewed as the product of the Soviet legacy and the patchy collapse of the USSR as well as the ill-conceived policies and mistakes of the involved parties, Russia and external actors – USA, NATO and EU.     

Freedom of Speech and Democracy in Malaysia

This article seeks to understand the situation of political speech in Malaysia, the argument in favour of restrictions on political speech, and the problems that prevent political speech from being practised effectively. For example, two particularly sensitive issues—ethnic rivalry and religion—are considered taboo and discussion of these issues is severely restricted. Article 10 of the Malaysian Constitution, in reflecting the sensitiveness of these issues, specifies a list of restrictions, which limit the right of free speech on the grounds of guarding political stability and racial harmony. Furthermore, freedom of political speech and the political rights of individuals are secondary to the goals of national prosperity and national development, and the government is predisposed to impose some form of political discipline in order to serve the greater social good. However, the Malaysian government has taken a step further to control not only hate and racial speech, but also any political speech that seriously challenges the government. In this respect, the Malaysian government can be accused of being less democratic for its restriction on political speech.     

Analysis of 13 tetrameric short tandem repeat loci in a population of Tuscany (Central Italy) performed by means of an automated infrared sequencer

Allele frequencies for the 13 STRs of the Combined DNA Index System (CODIS) core were obtained from a sample of 188 unrelated individuals living in the area of Florence, Prato and Pistoia (Tuscany, Central Italy).     

Primer composition and memory effect of weapons--some trends from a systematic approach in casework

Since 2008, our laboratory has adopted a systematic approach to the examination of gunshot residues (GSR) in casework by analysing, whenever possible, the inorganic composition present in ammunition (cartridge cases and unused ammunition). By compiling the results of these analyses in a database, it is possible to observe some trends during the period of interest: on the one hand, the prevalence of primers containing lead, barium and antimony is about 50%, and even as high as 70% when including lead-barium-antimony based primers also containing tin; on the other hand, the prevalence of non-toxic primers is for the time being very low. Still using the same approach, test firings were performed with recovered weapons and litigious ammunition whenever possible in order to estimate the influence of the well known "memory effect" of the weapons on the GSR analysis results. The first results show a quite strong memory effect for the .22 and the .32 caliber, unlike the .38 caliber. This is probably due to a high prevalence of lead-barium-antimony based primers for the latter caliber.     

Does political connection influence corporate financial decisions in unstable political environment?

The aim of this study is to examine the impact of political connection on the cost of debt, the cost of equity and the investment level in an unstable political environment. We use a sample of 55 Tunisian listed firms during the post-revolution period (2011–2018) and we apply a generalized least square (GLS) approach to test our hypotheses. Findings highlight that political connections increase the corporate financial costs and reduce the investment level. Furthermore, in an additional analysis, we show on the one hand that political instability negatively affects the investment and affects positively the cost of debt and the cost of equity. On the other hand, we make evidence that the political instability level negatively affects the relation between the political connection and the cost of debt. The contribution is, to the best of our knowledge, the absence of studies conducted in Tunisia countries examining the impact of political connection on the financial cost and investment level in an unstable political environment such as Tunisia.     

Contesting Mestizaje: Black Politics and Oral Traditions in Venezuela

Afro-descendant oral traditions are powerful modes of political expression that disrupt anti-black logics within Latin America's mestizaje. Scholarship on Afro-Latin American anti-racist mobilisation centres on large-scale, collective action. Instead, in this article, I examine songs and décimas, central forms of Afro-descendant cultural subjectivity. Drawing on thirteen months of ethnographic fieldwork in La Guaira state, Venezuela, I show how oral traditions are place-based forms of resistance against anti-black racism. This research calls on scholars to attend to oral traditions and their geographies as a tool of anti-racist political mobilisation.
