Powdered Activated Carbon: An Alternative Approach to Genomic DNA Purification

Forensic evidence samples are routinely found as stains on various substrates, which may contain substances known to inhibit polymerase chain reaction (PCR). The goal of this study was to evaluate post‐Chelex^®100 purification using powdered activated carbon (PAC). Mock crime scene DNA extracts were analyzed using quantitative PCR and short tandem repeat (STR) profiling to test the DNA recovery and inhibitor removal using PAC with those of the Amicon^®Ultra 100K. For extracted bloodstains on soil and wood substrates, PAC and Amicon^®Ultra 100K generated similar DNA yield and quality. Moreover, the two methods significantly decreased the concentration of humic substances and tannins compared to nonpurified extracts (p < 0.001). In instances where extracts contained indigo dye (bloodstains on denim), Amicon^®Ultra 100K performed better than PAC due to improved amplifiability. Efficient adsorption of humic substances and tannins, which are common inhibitors, indicates PAC's potential application in the purification of high‐template DNA extracts.     

The development of political science in Lithuania: Years of the breakthrough

Abstract. The development of political science was closely connected to the democratic changes and the restoration of statehood at the end of the 1980s in Lithuania. This paper examines the historical and contemporary social and academic roots of political science in the country. The other issue investigated in detail is the institutionalisation of political studies, which required the development of new academic curricula. Major vehicles for the institutionalization of political science were the decentralisation of academic activities and the establishment of new institutions, such as the Institute of Political Science and International Relations (University of Vilnius) and the Lithuanian Political Science Association, and intensive cooperation withWestern universities and funding organizations. Nonetheless, the growth and efficiency of political studies and research depend very much on their successful integration into the environment of the existing universities. The research output of Lithuanian political science is characterised by a widening of research interests and the further introduction of statistical and computer methods of investigation, with problems of Lithuania's foreign and security policy and issues of democratisation as topics of continuing popularity.     

Should competition policy in banking be amended during crises? Lessons from the EU

This article investigates the nexus of competition and stability in European banking. It analyzes the European legal framework for competition policy in banking and several cases that pertain to anti-cartel policy, merger policy, and state-aid control. It discusses whether and how competition policy should be amended in order to preserve the stability of the banking system during crises. The article argues for increased cooperation between prudential regulators and competition authorities, as well as an enhanced framework for bank regulation, supervision, and resolution that could mitigate the need to change competition policy in crisis times.     

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.     

Comparing colonial differences: Baltic literary cultures as agencies of Europe’s internal others

ABSTRACT

The article discusses the Baltic colonial experience in historical and comparative perspective. It sketches the ways in which Baltic societies are best linked to theoretical discussions on postcolonial issues, and whether they might be looked upon in a more global context. The main question posed by the article is in what ways Baltic identity has been determined by processes of foreign settlement, occupation and colonization of the territory of each respective country and whether we can see Baltic societies as potential agencies of Europe’s internal others.     

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.     

Building Italianità in Northern Adriatic: the case of organized migration of population from Pola/Pula

The article analyzes the process of building italianità in the case of migration of population from Pola/Pula that started as early as May 1945 and culminated in an organized process that officially began on 23 January 1947 and lasted until 20 March that same year. The article sheds light on the premises of that identity by analyzing complex activities of the Italian authorities who wanted to “defend Italianism” in Pola/Pula, as well as in other border areas of former Venezia Giulia. At the state level, they were mainly carried out by the Office for the Julian March/Ufficio per la Venezia Giulia and following reorganization beginning at the end of 1946 by the Office for Border Areas/Ufficio per le Zone di Confine, and at the local level by a network of pro-Italian organizations and groups. Analysis contributes to the understanding of the top-down and bottom-up italianità building process. On the local level, common identity was built upon the myth of the patria, reiteration of traumatic/“wounded” memories and victim presentation of the “Italian” population, fear to be separated from the patria, and unjust peace treaty propaganda. Simultaneously, the “Italian” population understood the Italian state as their defender.     

Advanced Framework for Digital Forensic Technologies and Procedures*

Abstract: Recent trends in global networks are leading toward service‐oriented architectures and sensor networks. On one hand of the spectrum, this means deployment of services from numerous providers to form new service composites, and on the other hand this means emergence of Internet of things. Both these kinds belong to a plethora of realms and can be deployed in many ways, which will pose serious problems in cases of abuse. Consequently, both trends increase the need for new approaches to digital forensics that would furnish admissible evidence for litigation. Because technology alone is clearly not sufficient, it has to be adequately supported by appropriate investigative procedures, which have yet become a subject of an international consensus. This paper therefore provides appropriate a holistic framework to foster an internationally agreed upon approach in digital forensics along with necessary improvements. It is based on a top‐down approach, starting with legal, continuing with organizational, and ending with technical issues. More precisely, the paper presents a new architectural technological solution that addresses the core forensic principles at its roots. It deploys so‐called leveled message authentication codes and digital signatures to provide data integrity in a way that significantly eases forensic investigations into attacked systems in their operational state. Further, using a top‐down approach a conceptual framework for forensics readiness is given, which provides levels of abstraction and procedural guides embellished with a process model that allow investigators perform routine investigations, without becoming overwhelmed by low‐level details. As low‐level details should not be left out, the framework is further evaluated to include these details to allow organizations to configure their systems for proactive collection and preservation of potential digital evidence in a structured manner. The main reason behind this approach is to stimulate efforts on an internationally agreed “template legislation,” similarly to model law in the area of electronic commerce, which would enable harmonized national implementations in the area of digital forensics.
