Analytical Characterization of Erythritol Tetranitrate,an Improvised Explosive

Erythritol tetranitrate (ETN), an ester of nitric acid and erythritol, is a solid crystalline explosive with high explosive performance. Although it has never been used in any industrial or military application, it has become one of the most prepared and misused improvise explosives. In this study, several analytical techniques were explored to facilitate analysis in forensic laboratories. FTIR and Raman spectrometry measurements expand existing data and bring more detailed assignment of bands through the parallel study of erythritol [¹⁵N₄] tetranitrate. In the case of powder diffraction, recently published data were verified, and ¹H, ¹³C, and ¹⁵N NMR spectra are discussed in detail. The technique of electrospray ionization tandem mass spectrometry was successfully used for the analysis of ETN. Described methods allow fast, versatile, and reliable detection or analysis of samples containing erythritol tetranitrate in forensic laboratories.     

Understanding Havel?

The presented article tries to make sense of Václav Havel, a man of many qualities and professions yet not a professional in the conventional sense of the word. The aim is to offer deeper insight into diverse cognitive elements which formed Havel's political reasoning and attitudes. The idea is to provide an alternative interpretation and get beyond the customary explanations expressed through traditional IR language seeing Havel as a dissident idealist who was pushed by some realist impulses to clearly define real political and later also geopolitical stands. In doing so, the article is divided into three parts. The first part discusses conceptual frameworks (rather than a single framework) within which Have saw and understood the political world. The middle part examines Havel's political agenda, namely the issues of the return to Europe, the German question, and relationships with Russia, the United States and toward multilateral institutions. The final part that utilizes primary data obtained through personal interviews with many Havel's close collaborators presents two faces of Václav Havel: the dramatist and the ideologue.     

Social Media Engagement of Berlin and Prague Museums

ABSTRACT

Attracting visitors and engaging them effectively in the highly competitive and saturated environment shaped by Web 2.0 and online social networking forces museums to creatively and purposefully examine channels for extended interaction with audiences. This exploratory and comparative research aims to compare the state of social media strategies across museums of two regions and to identify the influence of applied strategies on users’ reactions. The surveyed sample considers 296 museums from two European capitals—Berlin and Prague—whose activity has been observed during a three-month period. The findings identify the differences in the approaches of museums and suggest that the frequency and characteristics of published messages correlate to the level of fan reactions, facilitating targeted relationship-building possibilities with online audiences. They further imply that the museums can influence the engagement of visitors by focusing on the particular properties of their posts, both in the sense of post structure, media application, and underlying semantic features.     

Shooting Through Clothing in Firearm Suicides

Abstract: There is a longstanding empirical rule that people who commit suicide rarely shoot through their clothing, but rather put it aside to expose the nude skin. Signs of shots through clothing have always been considered suspicious, raising presumptions of the presence of an abettor. Our report, based on a retrospective study of fatal suicidal firearm injuries from the years 1980 to 2007, points out that suicide victims only rarely remove clothing from the site of the future entry wound. The report covered 43 cases with fatal gunshot wounds in the area of the thorax, with only four persons (9%) removing the clothing present in the area of the subsequent self‐inflicted wound. Defects present on the clothing of a victim cannot, therefore, be understood as an absolute criterion for disproving the possibility of suicide, and nor do they necessarily indicate an unfortunate accident or homicide. If, however, the suicide victim removes the clothing from the area of the future wound, then this is almost always an indication of suicide.

Analysis of Job Market in Germany and Spain in Order to Reduce Unemployment in Serbia

The percentage of unemployed in Germany was at the lower level than in Spain until 2004. In 2004, the percentage of jobless citizens in Germany almost reached Spanish average, while in 2005 and 2006, German unemployment rate even overcame Spanish one. During the period of the crisis, unemployment rate in Spain has been nearly five times higher than in Germany and more than two times higher than the average unemployment rate in the EU. Youth unemployment in Spain is 50%. On the other side, Germany is becoming even stronger in the period of crisis The incredible recovery that Germany experienced after World War II is commonly referred to as the Wirtschaftswunder, which translates into English as the ＂economic miracle＂. It can be said that Germany＇s successful recovery following the global financial crisis could justifiably be classified as the Wirtschaftswunder II. In Serbia, situation is much worse than in above-mentioned countries and it could not be concluded that it is just caused by the crisis. Periods of wars, economic sanctions and hyperinflation, as well as the transition process from the centrally planned to the market economy caused great number of jobs to be lost.     

Suicidal Decapitation by Guillotine: Case Report and Review of the Literature

Abstract: Suicidal decapitation is seldom encountered in forensic medicine practice. This study reports the analysis of a suicide committed by a 31‐year‐old man with a self‐fabricated guillotine. The construction of the guillotine was very interesting and sophisticated. The guillotine‐like blade with additional weight was placed in a large metal frame. The movement of the blade was controlled by the frame rails. The steel blade was triggered by a tensioned rubber band after releasing the safety catch. The cause of death was immediate exsanguination after complete severance of the neck. The suicide motive was most likely emotional distress after the death of his father. In medico‐legal literature, there has been only one similar case of suicidal complete decapitation by a guillotine described.     

A fatal elephant attack

A rare case of an elephant attack is presented. A 44-year-old man working as an elephant keeper was attacked by a cow elephant when he tripped over a foot chain while the animal was being medically treated. The man fell down and was consequently repeatedly attacked with elephant tusks. The man sustained multiple stab injuries to both groin regions, a penetrating injury to the abdominal wall with traumatic prolapse of the loops of the small bowel, multiple defects of the mesentery, and incomplete laceration of the abdominal aorta with massive bleeding into the abdominal cavity. In addition to the penetrating injuries, the man sustained multiple rib fractures with contusion of both lungs and laceration of the right lobe of the liver, and comminuted fractures of the pelvic arch and left femoral body. The man died shortly after he had been received at the hospital. The cause of death was attributed to traumatic shock.     

Conditions for effective large‐scale anticorruption efforts and the role of external actors: What does the Slovak experience tell us?

The article looks at what policy‐makers can do to decrease corruption in developing and transition countries, based on an in‐depth examination of effectiveness of actual anticorruption measures in Slovakia. The research presents a synthesis of 12 case studies where measures in the sectors most associated with corruption as well as horizontal measures were analysed. The research shows that corruption can be decreased significantly within several years and external actors can play a substantial role in the process. An overall decrease in corruption can be based on aggregation of individual sectoral changes in areas most suffering from graft. In particular, the Slovak strategy was based on a sector‐by‐sector economic approach to resolve supply–demand imbalances based on either liberalisation/privatisation, limitations on discretion or managing supply and/or demand. Horizontal reforms complemented by sectoral reforms with their strong focus on increasing transparency. Concerning the role of external actors, we conclude that even when there is a domestically driven anticorruption effort, the external actors can still help significantly by serving as sources of inspiration, legitimacy, know‐how and funding for reform design and implementation.

Terrorism-Free Zone in East Central Europe? Strategic Environment,Risk Tendencies,and Causes of Limited Terrorist Activities in the Visegrad Group Countries

The aim of this article is to analyse terrorism and the phenomena linked to it in East Central Europe. In comparison with a number of other regions of today's world, this area can currently seem to be a relatively “terrorism-free zone.” Although the number of terrorist attacks committed in this territory is insignificant, this does not mean that the risk of terrorism is entirely negligible in the region. This text explains some historical determinants of the current situation and describes the consequences both of regime change in the countries in question and of their foreign policy decisions after 1989. I also analyse the importance of East Central Europe as a logistical space for international terrorism (weapons procurement, stays of terrorists, etc.). I characterise the threats of Islamic and Middle Eastern terrorism in connection with the pro-American and pro-Israeli policies of East Central European countries, especially after 9/11, assess the risks posed by the domestic extremist scenes in those countries that have a relationship with terrorism, and take notice of the accusations of terrorism that have been voiced in international politics. On the basis of this data, I then provide an overview of the importance of East Central Europe for the contemporary study of terrorism.
