Challenging conventional views on mobile-telecommunications investment: evidence from conflict zones

Huge amounts are being invested in information and communication technologies (ICTs) such as mobile phones and their telecommunications infrastructure. Development agencies adopt a conventional view on the ‘climate’ needed to encourage such investment, believing particularly that good governance and security are required. We question this conventional view with a study of mobile telecommunications in three insecure states that score very badly in the Worldwide Governance Indicators. Data are limited, but they suggest that insecurity and ‘bad governance’ may not be the barriers to investment that are normally supposed. Indeed, it is possible – at least for this type of digital technology – that they may encourage investment.     

A rare mutation in the primer binding region of the Amelogenin X homologue gene

Use of Amelogenin locus typing as a gender marker incorporated in STR multiplexes is common practice in forensic genetics analysis. Among 5534 Polish male individuals tested using the SGMPlus kit, one was found to lack the amelogenin X-specific homologue (0.02%). The same result was obtained with other commercial kits which also amplify the amelogenin locus, namely ProfilerPlus and PowerPlex16. When alternative amelogenin primers external to but encompassing the initial amplicon were applied, an X homologue product was seen. Sequencing of the X homologue amelogenin allele revealed C to G mutation located at the most 3′ base of the commonly used amelogenin reverse primer. To our knowledge, this mutation and failure to amplify the X homologue of the amelogenin gene has not been reported for the European population.     

Rosa Vogelstein and her work: in search of the sources of success of the Stettin Women’s Association (Stettiner Frauenverein) at the turn of the twentieth century

At the turn of the twentieth century, Stettin, the major city of the Prussian Province of Pomerania, was the home of the Stettin Women’s Association (Stettiner Frauenverein). It engaged in welfare work as well as educational activity using modern forms of social work focused mostly on supporting lower-class women and children. This article presents the results of research into the sources of success of this organisation. It is worth attention because the organisation was established in a city where, similarly to the entire province, women’s movement demanding changes to behaviour patterns attributed to sex and background did not attract much support. In the light of preserved archives, it was Rosa Vogelstein, the wife of a local rabbi, who wielded decisive influence on this and who with full awareness resigned from exposing her role in the establishment and operations of the association which led to the memory of her achievements gradually fading.     

Human security of the Sámi in the new Sámi Arctic Strategy

ABSTRACT

Recent plans and enterprises of the Arctic States of Sweden, Norway and Finland – such as the Finnish plan to build a controversial rail line from Rovaniemi to Kirkenes in Norway, relocation of Swedish Kiruna (already in progress), building Markbydgen windfarm in Sweden or construction of a copper mine in Kvalsund, Norway - have put into question the human security of the Sámi. In this paper, the author examines the contents of the new document The Sámi Arctic Strategy. Securing enduring influence for the Sámi people in the Arctic through partnerships, education and advocacy adopted in 2019. Special emphasis is put on the reflections and references to human security of the Sámi. Then the author briefly examines the above examples and how they may or already affect human security of the Sámi. The research questions are: which parts of the new Sámi Arctic Strategy refer to human security? What is the importance of self-determination to human security of the Sámi? Could this Strategy facilitate implementation of the right of the Sámi to self-determination, and as a result improve their human security? The paper attempts to answer these questions in Concluding Remarks.     

Should gains from criminal knowledge be forfeited?

Crime, Law and Social Change - Nobody should profit from crime; this fundamental moral principle is uncontroversial. At the level of public declaration, few people are likely to disagree with this...     

Penetration Depth of Projectiles Fired from a Replica of Colt Navy of 1851 in 20% Gelatin Blocks Correlated with Fatal Injuries Assessed in an Autopsy of a 78‐Year‐Old Man

Pursuant to the Polish Weapons and Ammunitions Law, muzzle‐loading black powder weapons, manufactured before 1885, or their replicas, as well as suitable projectiles, can be possessed legally without registration and special licenses. The aim of the study was to assess the penetration depth of projectiles fired from a black powder weapon, replica of Colt Navy of 1851, in 20% gelatin blocks and to compare the obtained results with the actual injuries found on autopsy of a 78‐year‐old man who had committed suicide. In the experiments, we used the black powder weapon and ammunitions, as well as gelatin blocks serving as a soft tissue model. We ascertained that solid spherical projectiles fired from black powder weapons cause extensive injuries, especially in the initial segment of the wound canal. Additionally, based on the presence and location of the wad in the wound canal, the distance from which the shot was fired can be determined.     

Application of BioRobot M48 to forensic DNA extraction

The development of a nucleic acid extraction method based on magnetic separation has opened up possibilities forl automation of DNA extraction. The BioRobot M48 is one of robotic stations applicable to automated DNA extraction in forensics. However, each new method should be thoroughly validated before application to routine casework. Our aim was to compare the effectiveness of the currently utilized organic/Microcon 100 based extraction procedure and magnetic extraction with BioRobot M48. The DNA concentration of DNA extracts obtained from different kinds of typical forensic material was evaluated followed by amplification with the SGM Plus or Identifiler kit and capillary electrophoresis using ABI 3100 Avant. We can conclude that BioRobot M48 is a very effective instrument for DNA extraction from most specimens and can be successfully applied in forensic laboratories.     

Identification and characterization of 2,5-dimethoxy-4-nitro-β-phenethylamine (2C-N) - A new member of 2C-series of designer drug

The online sale of psychoactive substances, including hallucinogens, is becoming a serious problem in many countries. This paper presents and discusses the mass spectrometric, infrared spectroscopic and nuclear magnetic resonance spectroscopic data of 2,5-dimethoxy-4-nitro-β-phenethylamine (2C-N), which was identified in a powder sample seized by the authorities in 2011 in Poland. The molecular mass of 2C-N (226.0954amu) was confirmed in the LC/ESI-QTOFMS experiment. The molecular ion was also observed in the GC-EI/MS spectrum. A characteristic set of ions for the parent substance was found using both chromatographic methods, and when derivatization with trifuluoroacetic anhydride (TFAA) was applied. Two broad dominant bands at 1520cm(-1) and 1342/1322cm(-1), observed in the FTIR spectrum of 2C-N, originated from the nitro group. NMR spectroscopy helped unequivocal elucidation of the structure. The applied identification procedure proved to be a powerful tool to determine the structure of a new designer drug.
