title: Von Obertauern nach "Snowbertauern"
Creators: name: Wallner, Daniel Paul
Year: 2021

description: Die vorliegende Arbeit untersucht die Bedeutung von Schnee(un)sicherheit am Salzburger Obertauern. Sozial-ökologische, technik-geschichtliche und kultur- und sozialanthropologische Theorien bieten Ansätze, um ein komplexes Phänomen, wie jenes des Schnees und die Abhängigkeiten von diesem, zu ergründen. Der Ort zählt zu einer der größten Wintersportdestinationen in Österreich und erwirtschaftet 95 Prozent der Jahresumsätze von Ende November bis Anfang Mai. Eine starke Abhängigkeit besteht somit zum Vorhandensein von Schnee und der wintertouristischen Nische. Schnee bildet die Basis einer auf Wintertourismus basierten Ökonomie, die sich zunehmend auf die Kommodifizierung einer spezifischen Ausprägung des Wetters und Umwelt spezialisiert hat. Schneesicherheit als zentraler Begriff in der Markenstrategie von Obertauern wird mittels des Einsatzes von Technik versucht herzustellen. Eingebunden in ein sozio- technisches, sozio-ökologisches System lässt sich das Wetter aber nicht vollständig kontrollieren. Anpassungsstrategien an Umwelt und Ökonomie sind geprägt von technischen, aber auch sozialen, politischen und ökonomischen Faktoren. Interner wie externer Konkurrenzdruck bedingt zu großen Teilen vergangene und zukünftige Strategien.
description: The present work examines the importance of snow reliability and safety in Obertauern in Salzburg. Social-ecological, technological-historical and cultural and social anthropological theories offer approaches to explore a complex phenomenon such as that of snow and its dependencies on. The place is one of the largest winter sports destinations in Austria and generates 95 percent of annual sales from late November to early May. There is therefore a strong dependency on the presence of snow and the winter tourism niche. Snow forms the basis of an economy based on winter tourism, which has increasingly specialized in the commodification of a specific form of weather and the environment. Snow reliability, as a central concept in Obertauern's brand strategy, is tried to be achieved by using technology. Integrated into a socio-technical, socio-ecological system, the weather cannot be fully controlled. Adaptation strategies to the environment and the economy are shaped by technical, but also social, political and economic factors. Internal and external competitive pressures largely dictate past and future strategies.

description: Most bacteria contain protein filaments or filament systems collectively known as “bacterial cytoskeleton”. Similar to their counterparts in eukaryotic cells, bacterial cytoskeletal proteins are essential in temporal and spatial organization of cellular machineries. They have been implicated in a wide range of fundamental processes, such as cell division, morphogenesis, DNA segregation, and polarity establishment. In the stalked model organism Caulobacter crescentus (C. crescentus), there are structural homologues of typical eukaryotic cytoskeletal proteins, such as the tubulin homologue FtsZ, the actin homologue MreB, and the intermediate filament-like protein crescentin. In addition, an increasing number of bacteria-specific cytoskeletal proteins have been discovered in recent years, among them the bactofilins. Previous studies have demonstrated that bactofilins adopt beta-helical structures and polymerize spontaneously into stable filaments that have a variety of roles in bacteria. However, so far, many aspects of their biology remain unclear. 
In this work, we comprehensively investigated the properties of bactofilin using the homologue BacA from C. crescentus as a model. The aim is to elucidate its polymerization mechanism and its interaction with other proteins. The results showed that several conserved hydrophobic residues at the ends of the beta-helical bactofilin domain were crucial for the formation of protofilaments, which can further coalese into higher-order structures via lateral interactions, mediated by electrostatic forces. Moreover, studies of the membrane association of bactofilin not only indentified important amino acid residues for membrane-targeting but also revealed that polymerization and membrane binding are closely interdependent processes that promote each other. Additionally, the interaction between BacA and the penicillin-binding protein PbpC was analyzed in detail. Both interaction regions and the binding affinity were elucidated, which provides insights into the mode of interaction of bactofilins with client proteins. In an attempt to search for potential regulators of polymerization, various proteins were identified to interact with bactofilins in C. crescentus in vivo, indicating that bactofilins may play roles that go beyond their previously reported function in stalk biogenesis in this species. However, future studies are required to unravel the biological relevance of these interactions. Collectively, the findings made in this study for the first time shed light on the mode of action of bactofilins in C. crescentus, thus setting the basis for in-depth analyses of bactofilin function in other organisms.
title: Schülervorstellungen zum Recycling
Creators: name: Lindmaier, Kerstin
Year: 2021

description: Müllvermeidung, -sammlung, Wiederverwendung und Recycling sind Themen, die in den letzten Jahren immer mehr an Bedeutung gewonnen haben. Das gilt nicht nur für unseren Alltag, sondern auch für den Physikunterricht. In den Köpfen der Schülerinnen und Schüler existieren aber gerade zum Recycling immer noch Vorstellungen, die so nicht korrekt sind und deshalb unter Umständen den Lernfortschritt behindern könnten. Im Zuge dieser Arbeit werden daher mittels leitfadengestützten Interviews mögliche Schülervorstellungen zum Thema „Recycling“ ermittelt, um so ein Bewusstsein dafür bei den Lehrerinnen und Lehrern zu schaffen. Darüber hinaus erfolgt ein Abgleich, mit den bereits dokumentieren Forschungsergebnissen zu diesem Gebiet, um festzustellen, ob diese noch aktuell sind oder ob sich an den Annahmen der Schülerinnen und Schüler mittlerweile etwas geändert hat. Die Ergebnisse zeigen, dass einige Lernende z. B. Obst für recycelbar halten. Außerdem haben sie große Probleme damit, Recycling und Wiederverwendung zu unterscheiden. Sie halten Recycling für eine uneingeschränkte Umwelt- und Klimaschutzmaßnahme und vermuten, dass Batterien ähnlich wie Akkumulatoren wieder aufgeladen werden können. Das ist nur ein Teil der Resultate, die in dieser Arbeit dokumentiert sind. Er zeigt aber, dass hier eine Vielzahl an Schülervorstellungen den Denkweisen der Kinder und Jugendlichen zu Grunde liegen und Einfluss auf den Unterrichtsverlauf haben könnten. Umso wichtiger sind Arbeiten wie diese, die sie aufzeigen.
description: Reducing waste, collecting it, recycling and reusing are topics, that have grown more and more important over the last few years. Not only has that been the case in our everyday life`s but also in the physics classroom. However, there are still some misconceptions about recycling existing in students’ heads, that could be hindering the learning progress. In this thesis, using guided interviews, I determine said misconceptions, to create awareness in physic teachers. Furthermore, I compare my results with previously published studies on the same topic to investigate, whether they are still valid or if students’ perceptions have changed over the course of the last few years. The results show that some learners for example think, that fruits can be recycled. They also have difficulties to distinguish recycling and reusing. They take recycling for a total environmental- and climate protection measure and suspect, that Batteries can be recharged, just like accumulators. This is just a part of the results documented in this thesis. It shows however, that students’ ways of thinking are based upon numerous misconceptions, which can possibly influence the learning course in a negative way. Therefore, it is even more important to disclose them in a thesis like this.

description: Digitalisierung und neue Technologien stellen nicht nur eine Herausforderung für Wirtschaft und Gesellschaft, sondern auch für das Schulsystem dar. Die vorliegende Arbeit beschäftigt sich mit der Frage, welche Inhalte im Rahmen des Ethikunterrichts an der österreichischen BHS vermittelt werden können, um auf die zukünftigen Anforderungen der Gesellschaft und Arbeitswelt im Hinblick auf Digitalisierung und KI vorzubereiten. Zur Beantwortung der Forschungsfrage werden der Bildungsbegriff, der derzeitige Ist- Stand der Digitalisierung in Österreichs Schulen und der Ethik- Lehrplan untersucht, um zu klären, welche digitalen Kompetenzen im Ethikunterricht der Oberstufe erworben werden sollen. Mit einer qualitativen Inhaltsanalyse von LehrerInneninterviews und einem Unterrichtskonzept zum Thema „Digitale Ethik und Roboterethik“ wird gezeigt, dass eine Vielzahl der digitalen Kompetenzen, die in der Sekundarstufe II erworben werden sollen, im Ethikunterricht vermittelt werden können.
description: Digitalisation and new technology are not only challenging for economy and society, but also for education. The main aim of this thesis is, to explore potential content of Ethic lessons to be taught in Austrian upper secondary schools in order to prepare pupils for rising demands of society and economy in regard to digitalisation and AI. To answer the research question, the thesis analyses digitalisation within the Austrian education- system and the Ethics curriculum. The main goal is to clarify, which digital competences could be acquired in Ethic- lesson at Austrian upper secondary level. The qualitative analysis of interviews with teachers and a teaching concept about “digital ethics and robot- ethics” indicate, that numerous digital competences can indeed be taught in Ethic lessons.

subject: organizational readiness; change; CFIR; healthcare

description: Organizational readiness for change is considered a key precursor to successful implementation of complex change in the healthcare environment. Readiness, a key construct in the dissemination and implementation framework, can be predicted using readiness measures if organizational readiness can be reliably and validly assessed before a change project begins to obtain an accurate prediction of the likelihood of successful change. Through the ORC survey, the researcher or change implementer can identify barriers and enabling factors that affect readiness for change and thus take targeted steps to improve the success of change implementation.
title: Kontroversen über Observation nach dem Tavistock-Konzept
Creators: name: Seiler, Veronika
Year: 2021

description: In der vorliegenden Masterarbeit werden die Kontroversen über Observation nach dem Tavistock-Konzept analysiert. In der Analyse der drei Kontroversen stehen getätigte Aussagen über die Tavistock Observation Methode (TOM) im Vordergrund. Dabei wird überprüft, ob es sich um Aussagen für oder gegen TOM oder um Aussagen gegen die sachgemäße Anwendung der TOM handelt. Anschließend werden die Argumente themenspezifisch zusammengefasst, sodass eine Zusammenschau der Argumente und Gegenargumente über TOM entsteht. Als Ergebnis können drei kontrovers diskutierte Themen festgehalten werden. Erstens, der Einsatz von TOM als empirisch psychoanalytische Forschungsmethode. Zweitens, der Einsatz von TOM in der psychoanalytischen Ausbildung und drittens, die Möglichkeit einer therapeutischen Wirkung über Beobachtungen in der TOM. Aufbauend auf dieser Zusammenschau werden die Argumente und Gegenargumente diskutiert sowie auf offene Fragen hingewiesen. Es kann festgestellt werden, dass eine intensivere Auseinandersetzung mit den Fragen, ob die Psychoanalyse sowie die psychoanalytische Pädagogik eine empirische Wissenschaft ist und nach welchen Kriterien innerhalb der Psychoanalyse und psychoanalytischen Pädagogik geforscht werden kann, nötig ist. Zudem sollte der Einsatz von TOM in der Ausbildung konkretisiert und von Alternativen abgegrenzt werden. Aufgrund der Zusammenschau der Argumente und Gegenargumente über TOM bietet die vorliegende Masterarbeit eine Grundlage für weiterführende Diskussionen.
title: Einfluss der Covid-19 Pandemie auf die Beziehungsqualität von Paaren unter Berücksichtigung des erlebten Stresses und des dyadischen Copings
Creators: name: Lehner, Katharina
Year: 2021

description: Durch die Covid-19 Bedingungen wie Ausgangsbeschränkungen, Veränderungen im Arbeitsalltag oder Sorge aufgrund des Virus selbst hat sich das Leben vieler Menschen verändert. Es kann angenommen werden, dass diese Veränderungen Paarbeziehungen auf verschiedenste Art und Weise beeinflussen. Der Umgang mit sich verändernden Lebensumständen spielt eine wesentliche Rolle darin, wie stark der gegenwärtige Stress die Paarbeziehung beeinflusst. Ziel dieser empirischen Studie ist es daher, den Einfluss der Covid-19 Bedingungen auf die Beziehungsqualität unter Berücksichtigung des erlebten Stresses und des Ausmaßes des dyadischen Copings zu untersuchen. Durch eine nicht-experimentelle Querschnittsstudie an einer Stichprobe von 370 Personen, die sich in einer Partnerschaft befanden, wurden mittels eines Online-Fragebogens Daten erhoben. Die Ergebnisse veranschaulichen, dass sich bei einer Mehrheit die Beziehungsqualität verbessert hat oder gleichgeblieben ist. Weiters haben sich jene Paare, deren Beziehungsqualität sich verschlechtert hat, im Ausmaß des erlebten Stresses signifikant von Paaren mit verbesserter Beziehung unterschieden. Paare, die mehr Stress während der Pandemie erlebten, wiesen eine schlechtere Beziehungsqualität auf, als jene, die unter weniger Stress litten. Zudem wurde ein moderierender Effekt von dyadischem Coping auf den Zusammenhang zwischen dem gesamten Stress und der Beziehungsqualität gefunden. Weiters haben Analysen ergeben, dass es zwischen externalem Stress und der Beziehungsqualität einen kleinen mediierenden Effekt von paar-internem Stress gab. Die Ergebnisse zeigen, dass zufriedene Paare eine Stabilität gegenüber äußeren Einflüssen aufweisen. In krisenhaften Zeiten können Beziehungen eine Ressource darstellen und gesunde Beziehungen werden mehr wertgeschätzt.

description: The temperature dependence of the in-plane optical conductivity has been determined for Fe$_{1.03}$Te above and below the magnetic and structural transition at $T_N\simeq 68$ K. The electron and hole pockets are treated as two separate electronic subsystems; a strong, broad Drude response that is largely temperature independent, and a much weaker, narrow Drude response with a strong temperature dependence. Spectral weight is transferred from high to low frequency below $T_N$, resulting in the dramatic increase of both the low-frequency conductivity and the related plasma frequency. The change in the plasma frequency is due to an increase in the carrier concentration resulting from the closing of the pseudogap on the electron pocket, as well as the likely decrease of the effective mass in the antiferromagnetic state.

description: In this paper we set out to further explore the connection between isolated N=2 SCFT's in four dimensions and N=1 SCFT's in five dimensions. Using 5-brane webs we are able to provide IR Lagrangian descriptions in terms of 5d gauge theories for several classes of theories including the so-called TN theories. In many of these we find multiple dual gauge theory descriptions. The connection to 4d theories is then used to lift 4d N=2 S-dualities that involve weakly-gauging isolated theories to 5d gauge theory dualities. The 5d description allows one to study the spectrum of BPS operators directly, using for example the superconformal index. This provides additional non-trivial checks of enhanced global symmetries and 4d dualities.

title: Zwischen Ökonomie und Linguistik
Creators: name: Fink, Sarah
Year: 2021

description: Die Ökonomie beeinflusst das tägliche Leben eines jeden von uns maßgeblich. Durch das zunehmende Interesse der Bevölkerung an der wirtschaftlichen Entwicklung des Landes, welches vor allem dem aktuellen Zustand der Covid-19-Pandemie geschuldet ist, wird der Wirtschaftsbezug in nahezu jeder alltäglichen Situation in den Vordergrund gerückt. Vor allem in Hinblick auf solche Umstände ist das Beherrschen einer entsprechenden Fachspra-che von umso größerer Wichtigkeit, damit adäquate Kommunikation ermöglicht werden kann. Hier setzt die Linguistik an, welche der Fachsprache der Wirtschaft durch ihre sprach-lichen Besonderheiten erst ihren Ausdruck verleiht. Basierend auf dieser Thematik wird in der vorliegenden Arbeit der Frage der Verknüpfung und gegenseitigen Beeinflussung beider Disziplinen nachgegangen. Die empirische Untersuchung stützt sich hierbei auf Fachartikel des Bundesministeriums für Wirtschaft und Energie, welche auf deren Lexik, Syntax sowie textuelle Aspekte hin untersucht werden, um in weiterer Folge der Frage nachzugehen, in-wiefern sich die Fachsprache der Wirtschaft von der Gemeinsprache unterscheidet.
description: The economy has always had a significant impact on our daily lives. Over the last year, the situation of the Covid-19 pandemic has led to an increased interest in the economic develo-pment of our country, resulting in the awareness that everyday situation is closely related to the current economic conditions. This develeopment demnads the knowledge of a special language in order to be able to communicate accordingly with others and to provide and un-derstand the relevant information. In this regard, the disipline of Linguistics contributes sig-nificantly to the creation of a technical language used in the field of Business and Econo-mics, providing it with linguistic characteristics and a specialised terminology. This thesis deals with the link between the two disciplines of Linguistics and Economics and their mutu-al interference. The empirical section of the paper is based on specialist articles provided by the Federal Ministery of Economic Affiars and Energy and analyses them with regard to their lexical, syntactical and textual characteristics. Furthermore, The thesis will examine and define the differences between the technical language of Business and Economics and the general German language.

description: This thesis discusses the protumorigenic impact of Tc17 and Th17 cells on the tumor microenvironment (TME) of pancreatic ductal adenocarcinoma (PDAC) and ovarian cancer (OC).
Tc17 cells and their functions in PDAC have not been investigated so far. Here, we describe how Tc17 cells enhance tumor progression in this context. High levels of Tc17 in PDAC exhibited a strong correlation with tumor staging and reduced patient survival.
Tc17 cells, through the synergistic action of IL-17A and TNF, induced the differentiation of inflammatory cancer-associated fibroblasts (iCAF). Co-culture of pancreatic tumor cells with Tc17-iCAFs resulted in increased proliferation and elevated expression of antiapoptotic, as well as proliferation- and, metabolism-, associated genes. In different mouse models, we could confirm in vivo the tumor growth-promoting effect of Tc17-iCAFs on murine and human tumors, which was dependent on IL-17RA expression.
In OC, the prognostic value and the influence of Th17 cells on the TME is controversially discussed. Here, we demonstrated enrichment of Th17 cells in early omental metastases. Additionally, we identified mesothelial cells as targets for the classical Th17 cytokines, IL-17A and TNF. In primary omental mesothelial cells (MESO), IL-17A and TNF synergistically induce mesenchymal transition and an inflammatory phenotype. This phenotype was partially confirmed ex vivo via single-cell RNA sequencing. IL-17A and TNF disrupted the mesothelial monolayer integrity by downregulating tight-junction protein 1 (ZO1) expression and enhanced expression of the adhesion molecule VCAM-1. These changes facilitated increased attachment of tumor cells to the monolayer. As a positive feedback loop, the MESO secretome after IL-17A and TNF stimulation promoted differentiation of Th17 cells. In summary, we identified two novel, tissue-specific mechanisms of how different IL-17Aand
TNF-secreting cell populations mediate their protumorigenic properties via different players of the TME, fibroblasts and mesothelial cells, in PDAC, respectively OC.

description: We investigate an effective torsion curvature in a second order formalism underlying a two form world-volume dynamics in a $D_5$-brane. In particular, we consider the two form in presence of a background (open string) metric in a $U(1)$ gauge theory. Interestingly the formalism may be viewed via a non-coincident pair of $(D{\bar D})_5$-brane with a global NS two form on an anti brane and a local two form on a brane. The energy-momentum tensor is computed in the six dimensional CFT. It is shown to source a metric fluctuation on a vacuum created pair of $(D{\bar D})_4$-brane at a cosmological horizon by the two form quanta in the gauge theory. The emergent gravity scenario is shown to describe a low energy (perturbative) string vacuum in $6D$ with a (non-perturbative) quantum correction by a lower ($p<5$) dimensional $D_p$ brane or an anti brane in the formalism. A closed string exchange between a pair of $(D{\bar D})_4$-brane, underlying a closed/open string duality, is argued to describe the Einstein vacuum in a low energy limit. We obtain topological de Sitter and Schwarzschild brane universe in six dimensions. The brane/anti-brane geometries are analyzed to explore some of their characteristic and thermal behaviours in presence of the quantum effects. They reveal an underlying nine dimensional type IIA and IIB superstring theories on $S^1$.

description: A fundamental insight in the theory of diffusive random walks is that the mean length of trajectories traversing a finite open system is independent of the details of the diffusion process. Instead, the mean trajectory length depends only on the system's boundary geometry and is thus unaffected by the value of the mean free path. Here we show that this result is rooted on a much deeper level than that of a random walk, which allows us to extend the reach of this universal invariance property beyond the diffusion approximation. Specifically, we demonstrate that an equivalent invariance relation also holds for the scattering of waves in resonant structures as well as in ballistic, chaotic or in Anderson localized systems. Our work unifies a number of specific observations made in quite diverse fields of science ranging from the movement of ants to nuclear scattering theory. Potential experimental realizations using light fields in disordered media are discussed.

description: Using the frame formulation of multi-gravity in three dimensions, we show that demanding the presence of secondary constraints which remove the Boulware-Deser ghosts restricts the possible interaction terms of the theory and identifies invertible frame field combinations whose effective metric may consistently couple to matter. The resulting ghost-free theories can be represented by theory graphs which are trees. In the case of three frame fields, we explicitly show that the requirement of positive masses and energies for the bulk spin-2 modes in AdS$_3$ is consistent with a positive central charge for the putative dual CFT$_2$.

description: The next-to-leading-order contribution to the amplitude of a two-body decay process is a triangle-shaped diagram in which the unstable state is exchanged by the emitted particles. In this work we calculate this diagram in the framework of a scalar quantum field theory and we estimate its role in hadronic physics, i.e., we apply our results to the well-known scalar-isoscalar resonances $f_{0}(500)$, $f_{0}(980)$, $f_{0}(1370)$, $f_{0}(1500)$, $f_{0}(1710)$ and the scalar-isovector resonance $a_{0}(1450)$. It turns out that, with the exception of the broad resonance $f_{0}(500)$, the next-to-leading-order contribution is small and can be neglected.

description: We study $\mathbb{Z}_3$ symmetry-protected topological (SPT) phases in one-dimensional spin systems with $Z_3 \times Z_3$ symmetry. We construct ground-state wave functions of the matrix product form for nontrivial $\mathbb{Z}_3$ phases and their parent Hamiltonian from a cocycle of the group cohomology $H^2(Z_3\times Z_3,U(1))$. The Hamiltonian is an SU(3) version of the Affleck-Kennedy-Lieb-Tasaki (AKLT) model, consisting of bilinear and biquadratic terms of su(3) generators in the adjoint representation. A generalization to the SU($N$) case, the SU($N$) AKLT Hamiltonian, is also presented which realizes nontrivial $\mathbb{Z}_N$ SPT phases. We use the infinite-size variant of the density matrix renormalization group (iDMRG) method to determine the ground-state phase diagram of the SU(3) bilinear-biquadratic model as a function of the parameter $θ$ controlling the ratio of the bilinear and biquadratic coupling constants. The nontrivial $\mathbb{Z}_3$ SPT phase is found for a range of the parameter $θ$ including the point of vanishing biquadratic term ($θ=0$) as well as the SU(3) AKLT point [$θ=\arctan(2/9)$]. A continuous phase transition to the SU(3) dimer phase takes place at $θ\approx -0.027π$, with a central charge $c\approx3.2$. For SU(3) symmetric cases we define string order parameters for the $\mathbb{Z}_3$ SPT phases in a similar way to the conventional Haldane phase. We propose simple spin models that effectively realize the SU(3) and SU(4) AKLT models.

description: Die Qualität der maschinellen Übersetzung (MÜ) hat sich dank den neuronalen Systemen in den letzten Jahren dramatisch verbessert (vgl. Hassan et al. 2018 & Laki 2018 & Läubli et al. 2019 & Krüger 2018) und immer mehr Ressourcen werden in die Forschung sowie Entwicklung der neuronalen maschinellen Übersetzungssytemen (NMÜ) investiert (vgl. Tieber 2019: 12). Die vorliegende Masterarbeit beschäftigt sich damit, inwieweit NMÜ-Systeme im Übersetzungsprozess bereits Verwendung finden. Einerseits wird durch die Ergebnisse der Studie bestätigt, dass die befragten Personen sich mit NMÜ-Systemen bewusst auseinandersetzen und dass NMÜ-Systeme bereits im Alltag von FachübersetzerInnen Verwendung finden. Andererseits untersucht die Studie die Einführung sowie den Einsatz von NMÜ-Systemen durch freiberuflichen FachübersetzerInnen, Übersetzungsbüros sowie ein Industrieunternehmen. Weiterhin wird die Bezeichnung „Translation 4.0“ (Sandrini 2017: 150) beschrieben sowie Änderungen im Kompetenzprofil von FachübersetzerInnen infolge technologischer Entwicklungen werden vorgestellt (PACTE Kompetenzmodelle 1998 vs. 2003 & EMT Kompetenzmodelle 2009 vs. 2017).
description: The quality of machine translation (MT) has improved dramatically in recent years thanks to neural systems (Hassan et al. 2018 & Laki 2018 & Läubli et al. 2019 & Krüger 2018) and more resources are being invested in research as well as development of neural machine translation systems (NMT) (Tieber 2019: 12). This master’s thesis deals with the question, to which extent NMT systems are already used in the translation process. On the one hand, the results of the study confirm that the participants intentionally deal with NMT systems and that NMT systems are already used in the everyday life of professional translators. On the other hand, the study examines the implementation and use of NMT systems by freelance translators, translation agencies and an industrial company. Furthermore, the term "Translation 4.0" (Sandrini 2017: 150) is described and changes in the competence profile of translators due to technological developments are discussed (PACTE Competence Models 1998 vs. 2003 & EMT Competence Models 2009 vs. 2017).

description: We report the first lattice QCD calculation of the form factors for the standard model tree-level decay $B_s\to K \ellν$. In combination with future measurement, this calculation will provide an alternative exclusive semileptonic determination of $|V_{ub}|$. We compare our results with previous model calculations, make predictions for differential decay rates and branching fractions, and predict the ratio of differential branching fractions between $B_s\to Kτν$ and $B_s\to Kμν$. We also present standard model predictions for differential decay rate forward-backward asymmetries, polarization fractions, and calculate potentially useful ratios of $B_s\to K$ form factors with those of the fictitious $B_s\toη_s$ decay. Our lattice simulations utilize NRQCD $b$ and HISQ light quarks on a subset of the MILC Collaboration's $2+1$ asqtad gauge configurations, including two lattice spacings and a range of light quark masses.

description: Event-by-event fluctuations of the mean transverse momentum of charged particles produced in pp collisions at $\sqrt{s}$ = 0.9, 2.76 and 7 TeV, and Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV are studied as a function of the charged-particle multiplicity using the ALICE detector at the LHC. Dynamical fluctuations indicative of correlated particle emission are observed in all systems. The results in pp collisions show little dependence on collision energy. The Monte Carlo event generators PYTHIA and PHOJET are in qualitative agreement with the data. Peripheral Pb-Pb data exhibit a similar multiplicity dependence as that observed in pp. In central Pb-Pb, the results deviate from this trend, featuring a significant reduction of the fluctuation strength. The results in Pb--Pb are in qualitative agreement with previous measurements in Au-Au at lower collision energies and with expectations from models that incorporate collective phenomena.

description: Der humanistisch ausgerichtete Verein LOK – Leben ohne Krankenhaus –gewinnt als Akteur im psychosozialen Feld an Bedeutung, indem er versucht die Klient*innenperspektive in den Vordergrund der Betreuung zu stellen. Ziel der vorliegenden empirischen Arbeit ist es dabei zu verstehen, wie und was an einer persönlichen Betreuung aus Sicht der Klient*innen als wirksam wahrgenommen wird. Nach dem methodischen Vorgehen der Grounded Theory, supplementiert durch eine typenbildende Methodik, entwickeln sich theoretische Rückschlüsse induktiv aus dem Datenmaterial; in diesem Fall 53 leitfadengestützte Interviews sowie transdisziplinäre Workshops mit Klient*innen und Betreuer*innen. Durch dieses Vorgehen wird erkennbar, dass Klient*innen des Vereins die Betreuungsbeziehung entweder wie mit einem Freund, als beschützende Sicherheit oder als vorurteilsfreie Haltung wahrnehmen können. Sowohl der Recoveryansatz, welcher soziale Integration und klient*innenzentrierte Veränderungsprozesse anstrebt, als auch die Logotherapie, welche eine gemeinsame Sinnsuche in den Vordergrund stellt, helfen, das empirische Material auch theoretisch zu interpretieren.
description: The Viennese social enterprise LOK – Leben ohne Krankenhaus – is gaining prominence as an actor in the psycho social domain, as it emphasizes a client centered approach. Here, this text seeks to understand, what facilitates an efficacious relationship of care-taking from a client perspective. According to the Grounded Theory approach, supplemented with a type-building method, theoretical findings are developed inductively from the data; in this case 53 guided interviews and transdisciplinary workshops with clients as well as caretakers. Results indicate that client – caretaker - relationships can be perceived like a friendship, as a protected place or as an attitude free of prejudice. Both the recovery approach, focused on social integration and client-centered transformative processes, as well as logotherapy, putting the joint search for meaning to the forefront, help to interpret the empirical data in theoretical terms.

description: Die Masterarbeit befasst sich mit den Potentialen einer Auseinandersetzung mit literarischen Erzählungen innerhalb politikwissenschaftlicher Theoriebildung. Dies wird anhand der Frage erörtert, welchen Beitrag fiktionale Literatur (Romane) zur Verhandlung der Transformation(en) Osteuropas in transnational feministischen und postkolonialen Theoriedebatten leistet. Angesichts der andauernden Reaktivierung von Narrativen einer Rückkehr nach Europa und einer aufholenden Fortschrittsentwicklung der früheren Second World und heutigen Osteuropas in Medien, Wissenschaft und Alltag haben diese Debatten wichtige Impulse gesetzt, die Transformation(en) Osteuropas nach dem Zusammenbruch der Sowjetunion nicht länger als linearen Entwicklungsprozess einer abgrenzbaren Region zu mystifizieren, sondern diese als vielschichtige Verschiebungen globaler materieller und epistemischer Machtverhältnisse zu erforschen. Die Auseinandersetzung mit literarischen Erzählungen bietet dabei ein in der Politikwissenschaft bisher wenig ausgeschöpftes Potential, dominante Narrative der Transformationsforschung zu Osteuropa aufzubrechen. Indem die Romane „Spaltkopf“ von Julya Rabinowich (2011 [2008]) und „Das letzte rote Jahr“ von Susanne Gregor (2019) in der Masterarbeit als Gegenerzählungen zu etablierten Vorstellungen der Transformation(en) Osteuropas gelesen werden, wird gezeigt, wie ihre vielschichtigen Erzählweisen von Grenzziehungen zwischen und Transformationen von Vorstellungswelten einen wichtigen Beitrag zu kreativer, disziplinüberschreitender Theoriearbeit leisten.

description: Pancreatic ductal adenocarcinoma (PDAC) is one of the leading causes of cancer-related deaths in western industrialized nations. The low 5-year survival rate of 18.8% 21 can be explained by the lack of diagnostic options and therapeutic strategies. Therefore, research into prognostic and therapeutic approaches is becoming increasingly important. Changes at the molecular level have been observed in tumor cells and the tumor microenvironment. However, only few data are available showing the impact of these changes on patient survival. The focus of this work was to generate survival data from 91 PDAC patients treated in our department.
For this purpose, exosomes were purified from patient samples. Their size and concentration were measured using nano-flow cytometry (FCM). However, the determined distribution could not be linked to an overall survival pattern.  
From our data, the median survival is 21 months after diagnosis of Pancreatic cancer (PC).  Patients assigned to the short-term survival group (≤21 months) were predominantly of high tumor stage according to the 2017 UICC-TNM (Union for International 64 Cancer Control; tumor, node, metastasis) classification. 
PCR and Western Blotting were used to display the expression patterns of tetraspanins CD9 and CD81 in EVs derived from pancreatic tumor cells.
For both CD9 and CD81, an inverse correlation was shown between strong expression levels and poor prognosis of PDAC patients after complete surgical resection (R0). However, only the CD9 data could show a significant difference, while for future projects a larger cohort of patients would be interesting for CD81 to obtain significant results.  
PCR followed by immunohistochemical staining was used to describe the distribution pattern and expression levels of ADAM8, PRMT1 and TLR-7 in tumor cells its surrounding stromal cells from over 70 PDAC patients. 
In addition, the amount of ADAM8+ neutrophils in the postcapillary venules in PDAC sections was quantified. Remarkably, the amount of ADAM8+ neutrophils could be correlated with post-operative patient survival time. In contrast, no linkage could be shown between survival time and overall ADAM8 expression levels. 
While high PRMT1 protein expression levels were shown to be favorable for the prognostic outcome of patients, TLR-7 was over-expressed in samples from patients with short survival time.
From our observations, we conclude that changes in tumor cells and their micromilieu-specific stromal cells at the molecular level have a remarkable impact on the overall survival of PDAC patients.
Therefor they show prognostic potential and could be an interesting target for therapeutic approaches.

description: The search for aesthetic perfection grows every day, especially with the new era of social networks that focus on beauty and its components. As orthodontic treatment plays an important role in the design of the smile, its components and in increasing its attractiveness, the need to analyze the orthodontic factors that can alter esthetic perception has become increasingly important. The attractiveness of the smile can be considered an important social and aesthetic factor, as it can participate in the creation of personalities and enhance social interactions. Taking this into account, it is necessary to map the characteristics that can influence the attractiveness of the smile.

description: This paper deals with the weak error estimates of the exponential Euler method for semi-linear stochastic partial differential equations (SPDEs). A weak error representation formula is first derived for the exponential integrator scheme in the context of truncated SPDEs. The obtained formula that enjoys the absence of the irregular term involved with the unbounded operator is then applied to a parabolic SPDE. Under certain mild assumptions on the nonlinearity, we treat a full discretization based on the spectral Galerkin spatial approximation and provide an easy weak error analysis, which does not rely on Malliavin calculus.
