zur Praxis des Zeugenschutzgesetzes
No full textSoftcover, 372 S.: 22,00 €Softcover, 17x24Die Autorin beleuchtet die Praxis der Videovernehmung kindlicher Zeugen. Ausgangspunkt ihrer empirischen Untersuchung ist die Frage, ob die Gesetzesreform nicht nur gut gemeint ist, sondern auch praktisch umgesetzt werden kann. Hierbei knüpft sie an die Regelungen des 1998 geschaffenen Zeugenschutzgesetzes an, zu dessen Umsetzbarkeit im Sinne eines vom Gesetzgeber intendierten effektiven Opferschutzes, insbesondere der Vermeidung der sog. sekundären Viktimisierung (Traumatisierung), Experten aus Niedersachsen - Staatsanwaltschaft, Polizei und Gerichte - von ihren ersten Erfahrungen berichten. In fünf ausgewählten niedersächsischen Landgerichtsbezirken hat die Autorin zudem eine umfangreiche Aktenanalyse zum Einsatz von Videovernehmung durchgeführt und gelangt zu dem Ergebnis, dass die Videotechnologie im Strafverfahren so gut wie nicht eingesetzt wird. In konkreten Reformvorschlägen de lege ferenda werden auch die neueren Regelungen des Opferrechtsreformgesetzes von 2003 wertend in die Untersuchung einbezogen.The author examines the practice of video interrogation for children witnesses. Starting point for their empirical investigation is the question of whether the law reform is not only meant well, but can be implemented practically. Here the author builds on the regulations of the 1998 established law for witness protection, to its feasibility in terms of the intended effective protection of victims, particularly the avoidance of so-called secondary victimization (trauma), experts from the federal state of Lower Saxony - prosecutors, police and courts - report by their own experiencees. In five selected district courts of Lower Saxony, the author has also conducted an extensive document analysis on the use of video testimony, and concluded that the video technology in criminal proceedings is used rarely. In specific reform proposals „de lege ferenda“ also the recent regulations of the Law Reform Act of 2003 victims are included in the evaluative study

Constituent Information department of the University of Gothenburg (Informationsenheten vid Göteborgs universitet)
Course Master thesis in media and communications at the institution for journalism, media and communication at the University of Gothenburg
Term Spring 2013
Pages/ word count 77/ 32211 words
Objective To examine why researchers at the University of Gothenburg chose to blog in their role as a researcher
Method Exploratory analysis of qualitative, semi-structured interviews
Material Eleven interviews with blogging researchers from different fields at the University of Gothenburg, material gathered in spring 2012
Main results In the context of research communication blogs play an essential role for researchers for directly communicating with the public. A strong motivation for researchers to blog is that they can represent and create an image of themselves. Also the blog is
used in several ways as a tool in the researchers’ daily work.
Despite the fact that there are disadvantages with blogging, the researchers in the study find that it brings along far more advantages than disadvantages, which is why they keep blogging

Yang–Mills solutions and dyons on cylinders over coset spaces with Sasakian structure
No full textAbstractWe present solutions of the Yang–Mills equation on cylinders R×G/H over coset spaces of odd dimension 2m+1 with Sasakian structure. The gauge potential is assumed to be SU(m)-equivariant, parameterized by two real, scalar-valued functions. Yang–Mills theory with torsion in this setup reduces to the Newtonian mechanics of a point particle moving in R2 under the influence of an inverted potential. We analyze the critical points of this potential and present an analytic as well as several numerical finite-action solutions. Apart from the Yang–Mills solutions that constitute SU(m)-equivariant instanton configurations, we construct periodic sphaleron solutions on S1×G/H and dyon solutions on iR×G/H
Voxel-based additive manufacturing of biomimetic hard-soft materials: A fundamental study on the effect of biomimetic design parameters on fracture properties
No full textThe fracture properties of natural materials often outperform artificial material properties. This could be explained by their complex multi-scale (anisotropic) hard-soft material structure, starting at a nano-scale. The interest in the fabrication of complex biomimetic hard-soft materials and interfaces is growing due to their high fracture properties, including stiffness, strength and fracture toughness. Additive manufacturing, in particular voxel-based additive manufacturing, enables the precise mimicking of complex natural three-dimensional (3D) structures at a micro-scale. Various studies have been performed on the fabrication of biomimetic materials with an Objet500 Connex3 polyjet printer which is able to print multiple materials at the same time. However, fundamental research on the influence of multiple biomimetic design parameters on the fracture properties of hard-soft materials was missing. In this study the isolated and modulated effects of three different biomimetic design parameters on the fracture properties of hard-soft material samples were analysed. The samples differed in length scale (40, 240, 480 and 960 µm), hard material ratio (0, 25, 38, 50, 63, 75 and 100 %) and hard-soft material arrangement (semi-ordered, random and ordered). These design parameters could be found among different natural materials and interfaces. The fracture properties of the single edge notched samples, including stiffness, fracture strength, final strain and fracture toughness, were obtained with a tensile test. The effect of the different design parameters on the fracture properties was further analysed with digital image correlation (DIC) measurements and a digital microscope. The results show that the biomimetic design parameters had a modulated effect on the fracture properties. The fracture properties were mostly affected by the hard material ratio and length scale compared to the hard-soft material arrangement. A higher amount of hard material resulted in a higher stiffness and fracture strength, but in a smaller final strain. A smaller length scale improved the fracture properties if a significant amount of soft material was present. An important result is that the fracture toughness of the hard-soft material samples could be increased by nearly two times compared to the toughness of the individual constituents, supporting the potential of using biomimetic design parameters. The effect of the biomimetic design parameters on the fracture properties can be explained by the DIC measurements and digital microscope images. The microscope images show that the fracture path tended to propagate through the soft material phases, which was more difficult at a smaller length scale. DIC measurements showed that the plasticity zone in front of the crack tip was larger for the samples printed at native resolution, resulting in a higher fracture toughness. This study shows that a wide range of fracture properties can be achieved by regulating the length scale, hard material ratio and hard-soft material arrangement of hard-soft materials. The fracture toughness of hard-soft materials can be improved in comparison to the fracture toughness of the individual constituents, which supports the potential of using biomimetic design parameters in improving the fracture properties of hard-soft materials
Personality traits-based terrorism risk assessment: Determining reliability using open-source data
No full textThe chapter, "Personality traits-based terrorism risk assessment: Determining reliability using open-source data" was written by the listed authors including Logan Macnair (Douglas College Faculty). It is part of the "NATO Science for Peace and Security Series - E: Human and Societal Dynamics" series. Prominent terrorism case studies of individuals such as Omar Mateen, Dylann Roof, and Mohammed Merah indicate the need for personality trait-based terrorism risk assessment/threat assessment (TR/TA). This chapter provides an overview of Corrado’s, personality-based TR/TA instrument (see Chapter 14) by explaining the origin of each domain and the purpose of inclusion. Furthermore, this chapter displays results from a preliminary instrument validation study conducted on an open-source sample of 158 terrorists. Results of this study suggest strong statistical significance for many of the domains. This suggests the need for future inclusion of personality-based indicators in terrorism risk assessment. --From publisher description.Published
