description: Cosmic ray muon flux is measured by the coincidence technique using plastic scintillation detectors in the High Energy Physics detector laboratory at Bose Institute, Kolkata. Due to the COVID19 outbreak and nationwide complete lockdown, the laboratory was closed from the end of March 2020 till the end of May 2020. After lockdown, although the city is not in its normal state, we still were able to take data on some days. The lockdown imposed a strict restriction on the transport service other than the emergency ones and also most of the industries were shut down in and around the city. This lockdown has significant effect on the atmospheric conditions in terms of change in the concentration of air pollutants. We have measured the cosmic ray flux before and after the lockdown to observe the apparent change if any due to change in the atmospheric conditions. In this article, we report the measured cosmic ray flux at Kolkata (22.58$^{\circ}$N 88.42$^{\circ}$E and 11~m Above Sea Level) along with the major air pollutants present in the atmosphere before and after the lockdown.

description: We present a new theory which describes the collection of all tunnels of tunnel number 1 knots in the 3-sphere (up to orientation-preserving equivalence in the sense of Heegaard splittings) using the disk complex of the genus-2 handlebody and associated structures. It shows that each knot tunnel is obtained from the tunnel of the trivial knot by a uniquely determined sequence of simple cabling constructions. A cabling construction is determined by a single rational parameter, so there is a corresponding numerical parameterization of all tunnels by sequences of such parameters and some additional data. Up to superficial differences in definition, the final parameter of this sequence is the Scharlemann-Thompson invariant of the tunnel, and the other parameters are the Scharlemann-Thompson invariants of the intermediate tunnels produced by the constructions. We calculate the parameter sequences for tunnels of 2-bridge knots. The theory extends easily to links, and to allow equivalence of tunnels by homeomorphisms that may be orientation-reversing.
description: This version has extensive minor rewriting for accuracy and clarity. The material on the depth invariant has been substantially expanded and moved into a new ArXiv preprint, The depth of a knot tunnel.

description: Using game theory we provide mathematical proof that if a species of asexually reproducing microbes does not possess maximum variability in competitive abilities amongst its individual organisms, then that species is vulnerable to replacement by competitors. Furthermore, we prove that such maximally variable species are neutral towards each other in competition for limited resources; they coexist. Our proof is constructive: given one species which does not possess maximum variability, we construct a species with the same (or lower) mean competitive ability which can invade, in the sense that its expected value in competition is positive whereas the expected value of the non-maximally variable species is negative. Our results point towards the mechanistic underpinnings for the frequent observations that (1) microbes are characterized by large intra-specific variability and that (2) the number of extant microbe species is very large.

description: We present precise stellar radial velocity measurements for the K giant star Beta Gem spanning over 25 years. These data show that the long period low amplitude radial velocity variations found by Hatzes & Cochran (1993) are long-lived and coherent. An examination of the Ca II K emission, spectral line shapes from high resolution data (R = 210,000), and Hipparcos photometry show no significant variations of these quantities with the RV period. These data confirm the planetary companion hypothesis suggested by Hatzes & Cochran (1993). An orbital solution assuming a stellar mass of 1.7 M_sun yields a period, P = 589.6 days, a minimum mass of 2.3 M_Jupiter, and a semi-major axis, and a = 1.6 AU. The orbit is nearly circular (e = 0.02). Beta Gem is the seventh intermediate mass star shown to host a sub-stellar companion and suggests that planet-formation around stars much more massive than the sun may common.

description: The combination of huge databases of galaxy spectra and advances in evolutionary synthesis models in the past few years has renewed interest in an old question: How to estimate the star formation history of a galaxy out of its integrated spectrum? Fresh approaches to this classical problem are making it possible to extract the best of both worlds, producing exquisite pixel-by-pixel fits to galaxy spectra with state-of-the-art stellar population models while at the same time exploring the fabulous statistics of mega-surveys to derive the star-formation and chemical enrichment histories of different types of galaxies with an unprecedented level of detail. This review covers some of these recent advances, focusing on results for late-type, star-forming galaxies, and outlines some of the issues which will keep us busy in the coming years.

Wir stellen eine Erweiterung des Testwerkzeugs Peass vor, mit dem die Regressionstestselektion für PRBs möglich wird. Hierbei werden PRBs unterstützt, die mit dem Benchmarkingframework jmh4 implementiert sind.

The political economy of labor and student mobilizations in egypt 1919 - 2011 : a social movement theory approach
Creators: name: Abdel Ghafar, Adel
Publisher: name: Canberra, ACT : The Australian National University
Year: 2018

description: This thesis investigates the political economy of the Egyptian labor and student movements. It uses elements of social movement theory, specifically: political opportunities and threats, framing, diffusion and spillover within a broad political economy framework to assess mobilizations by the labor and student movement in four eras of contemporary Egyptian history: the pre-1952 era, the Nasser Era, the Sadat Era, and the Mubarak Era. The thesis examines how both movements responded to the political economy pressures of the respective eras. Within the context of social movement theory, the thesis argues that political opportunities such as institutional access, elite conflict, regime weakness and international dynamics have had an impact on mobilizations by both movements. Similarly, the thesis argues that threats such as state-attributed economic problems, erosion of rights and state repression have also affected mobilizations by both movements. In addition, despite the authoritarian nature of successive Egyptian regimes, the labor and student movement were at times able to affect government policies, as well as seriously challenge an incumbent regime in 2011. The thesis also demonstrates that diffusion and spillover processes have occurred between both movements, and that they have been more successful in challenging the authorities when such processes occur. Finally, the thesis examines the limitations of such diffusion and spillover processes, and argues that the inability of both movements to sustain momentum in the long term is due to cooptation efforts by established political forces and the absence of viable and enduring organizational structures that are autonomous of state control.

description: Entanglement is one of the quantum mechanical properties to which recently emerging quantum computers attribute an exponential increase in computing power. however, these systems are subject to a set of noise-inducing physical processes and hardware-level imperfections that render the results from quantum circuits erroneous. Bridging the time until sufficient qubits are available to compensate for these effects, quantum error mitigation algorithms aim at improving the result accuracy on near-term quantum devices. This empirical investigation describes and compares customary fundamental approaches to error mitigation for quantum states in condition of entanglement on real quantum computers. It is demonstrated that two readily implementable techniques regarding circuit design and measurement error mitigation may lead to a considerable increase in the quality of results.
title: Coming-out im Wandel
Creators: name: Scharfmüller, Lorenz
Year: 2023

description: Für queere Menschen ist das Coming-out eine der prägendsten Phasen ihres Lebens. Sie umfasst nicht nur die Kommunikation der eigenen Sexualität oder des Geschlechts nach außen, sondern beginnt schon Jahre – in manchen Fällen Jahrzehnte – davor und beschreibt den Weg von der ersten Liebe oder dem ersten Gefühl nicht wie die anderen zu sein über das Kennenlernen des eigenen Selbst, inklusive eventueller Selbstablehnung und Selbstverleugnung bis hin zum Akzeptieren und Annehmen dieses Andersseins. Sie umfasst Höhen und Tiefen. Freude und Schmerz. Die vorliegende Masterarbeit hat mit einem Generationenvergleich untersucht, welchen Unterschied es für Menschen macht, ob ihnen während ihres Coming-out-Prozesses bereits soziale Medien als Hilfsmittel zur Verfügung standen oder nicht. Die Ergebnisse zeigen, dass soziale Medien vor allem für das innere Coming-out, also die Phase der Selbstfindung, einen essentiellen Unterschied machen und Gleichgesinnte zueinander bringt, die ohne sozialen Medien mit dieser herausfordernden Phase ganz alleine wären. Zugleich ist eine Verkürzung dieser inneren Coming-out-Phase erkennbar, wie sie auch bereits von anderen Untersuchungen festgestellt wurde. Es obliegt weiterer Forschung, welche Rolle soziale Medien für diese Verkürzung spielen.
description: For queer people, coming out is one of the most formative phases of their lives. It not only involves communicating one's sexuality or gender to the outside world, but begins years - in some cases decades - before that and describes the path from first love or the first feeling of not being like the others, to getting to know one's own self, including possible self-rejection and self-denial, to accepting and embracing this otherness. It includes highs and lows. Joy and pain. This thesis used a generational comparison to investigate the difference it makes for people whether or not they already had social media available to them as a tool during their coming-out-process. The results show that social media makes a significant difference, especially for the inner coming out and brings like-minded people together who would be completely alone in this challenging phase without social media. At the same time, a shortening of this inner coming-out phase is recognizable, as has already been established by other studies. Further research is needed into the role that social media plays in this shortening.

description: Die vorliegende Masterarbeit befasst sich mit den Ansichten und Gedanken von aktiven Bewegung und Sport Lehrpersonen an Polytechnischen Schulen und Fachmittelschulen zur Legitimation des Unterrichtsfaches Bewegung und Sport, sowie den Zielen, Inhalten und Methoden, die in der Praxis zum Einsatz kommen. Zusätzlich werden die sportlichen Biografien der Proband:innen beleuchtet, um herauszufinden, wodurch deren Überzeugungen beeinflusst werden. Zu diesem Zweck werden acht leitfadengestützte Expert:inneninterviews mit Bewegung und Sport Lehrer:innen durchgeführt, die an Wiener Polytechnischen Schulen und Fachmittelschulen unterrichten und am Anfang ihrer Berufstätigkeit stehen. Der Interviewleitfaden orientiert sich an bereits bestehenden qualitativen Forschungsarbeiten und Ergebnissen der Literaturrecherche zu den Ansichten und Zielen von Bewegung und Sport Lehrkräften. Die Auswertung erfolgt nach den Vorgaben der Qualitativen Inhaltsanalyse nach Mayring und zeigt in ihren Ergebnissen ein sehr heterogenes Bild. Als eines der Leitmotive kann jedoch der Wunsch genannt werden, den Schüler:innen ein möglichst breites Spektrum an Sport- und Bewegungsaktivitäten zu bieten, um ihnen damit auch außerhalb der Schule einen bewegungsreichen und sportlichen Lebensstil zu ermöglichen.
description: This master's thesis deals with the views and thoughts of physical education teachers at polytechnic schools and technical secondary schools on the legitimation of the teaching subject of exercise and sport, as well as the goals, content and methods that are used in practice. In addition, the sporting biographies of the test subjects are examined in order to find out what influences their beliefs. For this purpose, eight guideline-based expert interviews will be carried out with physical education teachers who teach at Vienna polytechnic schools and technical secondary schools and are at the beginning of their careers. The interview guide is based on existing qualitative research and results of literature research on the views and goals of physical education teachers. The evaluation is carried out according to the specifications of the qualitative content analysis according to Mayring and shows a very heterogeneous picture in its results. However, one of the guiding principles is the desire to offer students the widest possible range of sports and exercise activities in order to enable them to enjoy an active and sporty lifestyle outside of school.

description: We have studied strange star properties both at zero temperature and at finite temperatures and searched signatures of strange stars in gamma-ray, x-ray and radio astronomy. We have a set of Equations of State (EoS) for strange quark matter (SQM) and solving the TOV equations, we get the structure of strange stars. The maximum mass for a strange star decreases with the increase of temperature, because at high temperatures, the EoS become softer. One important aspect of strange star is that, surface tension depends on the size and structure of the star and is significantly larger than the conventional values. Moment of inertia is another important parameter for compact stars as by comparing theoretical values with observed estimate, it is possible to constrain the dense matter Equation of State. We hope that this approach will help us to decide whether the members of the double pulsar system PSR J0737-3039 are neutron stars or strange stars.

description: We provide a Lawvere-style definition for partial theories, extending the classical notion of equational theory by allowing partially defined operations. As in the classical case, our definition is syntactic: we use an appropriate class of string diagrams as terms. This allows for equational reasoning about the class of models defined by a partial theory. We demonstrate the expressivity of such equational theories by considering a number of examples, including partial combinatory algebras and cartesian closed categories. Moreover, despite the increase in expressivity of the syntax we retain a well-behaved notion of semantics: we show that our categories of models are precisely locally finitely presentable categories, and that free models exist.

With the meson-hyperon couplings determined by the experimental binding energies of single-$Λ$ hypernuclei, we present a self-consistent calculation of double-$Λ$ hypernuclei in the relativistic mean-field theory, and discuss the influence of hyperons on the nuclear core. The contribution of two mesons with dominant strange quark components (scalar $σ^*$ and vector $ϕ$) to the $ΛΛ$ binding energy of double-$Λ$ hypernuclei is examined.

description: Computational physics is an important tool for analysing, verifying, and -- at times -- replacing physical experiments. Nevertheless, simulating quantum systems and analysing quantum data has so far resisted an efficient classical treatment in full generality. While programmable quantum systems have been developed to address this challenge, the resources required for classically intractable problems still lie beyond our reach. In this work, we consider a new target for quantum simulation algorithms; analysing the data arising from physics experiments -- specifically, muon spectroscopy experiments. These experiments can be used to probe the quantum interactions present in condensed matter systems. However, fully analysing their results can require classical computational resources scaling exponentially with the simulated system size, which can limit our understanding of the studied system. We show that this task may be a natural fit for the coming generations of quantum computers. We use classical emulations of our quantum algorithm on systems of up to 29 qubits to analyse real experimental data, and to estimate both the near-term and error corrected resources required for our proposal. We find that our algorithm exhibits good noise resilience, stemming from our desire to extract global parameters from a fitted curve, rather than targeting any individual data point. In some respects, our resource estimates go further than some prior work in quantum simulation, by estimating the resources required to solve a complete task, rather than just to run a given circuit. Taking the overhead of observable measurement and calculating multiple datapoints into account, we find that significant challenges still remain if our algorithm is to become practical for analysing muon spectroscopy data.

description: For any given partial order in a $d$-dimensional euclidean space, under mild regularity assumptions, we show that the intersection of closed (generalized) intervals containing more than 1/2 of the probability mass, is a non-empty compact interval. This property is shared with common intervals on real line, where the intersection is the median set of the underlying probability distribution. So obtained multivariate medians with respect to a partial order, can be observed as special cases of centers of distribution in the sense of type D depth functions introduced by Y. Zuo and R. Serfling, {\em Ann. Stat.}, {\bf 28} (2000), 461-482. We show that the halfspace depth function can be realized via compact convex sets, or, for example, closed balls, in place of halfspaces, and discuss structural properties of halfspace and related depth functions and their centers. Among other things, we prove that, in general, the maximal guaranteed depth is $\frac{1}{d+1}$. As an application of these results, we provide a Jensen's type inequality for functions of several variables, with medians in place of expectations, which is an extension of the previous work by M. Merkle, {\em Stat. Prob. Letters}, {\bf 71} (2005), 277--281.}

description: We attempt to fit cosmological data using $f(R)$ modified Lagrangians containing inverse powers of the Ricci scalar varied with respect to the metric. While we can fit the supernova data well, we confirm the $a\propto t^{1/2}$ behaviour at medium to high redshifts reported elsewhere and argue that the easiest way to show that this class of models are inconsistent with the data is by considering the thickness of the last scattering surface. For the best fit parameters to the supernova data, the simplest 1/R model gives rise to a last scattering surface of thickness $Δz\sim 530$, inconsistent with observations.

description: The competition between spin glass, ferromagnetism and Kondo effect is analysed here in a Kondo lattice model with an inter-site random coupling $J_{ij}$ between the localized magnetic moments given by a generalization of the Mattis model which represents an interpolation between ferromagnetism and a highly disordered spin glass. Functional integral techniques with Grassmann fields have been used to obtain the partition function. The static approximation and the replica symmetric ansatz have also been used. The solution of the problem is presented as a phase diagram giving $T/{J}$ {\it versus} $J_K/J$ where $T$ is the temperature, $J_{K}$ and ${J}$ are the strengths of the intrasite Kondo and the intersite random couplings, respectively. If $J_K/{J}$ is small, when temperature is decreased, there is a second order transition from a paramagnetic to a spin glass phase. For lower $T/{J}$, a first order transition appears between the spin glass phase and a region where there are Mattis states which are thermodynamically equivalent to the ferromagnetism. For very low ${T/{J}}$, the Mattis states become stable. On the other hand, it is found as solution a Kondo state for large $J_{K}/{J}$ values. These results can improve the theoretical description of the well known experimental phase diagram of $CeNi_{1-x}Cu_{x}$.

description: This thesis adopts a novel approach to resolving the present difficulties experienced by the courts in determining whether to impose strict liability for the wrongdoing of another in tort. It looks beyond the traditional classifications of 'vicarious liability' and 'liability for breach of a non-delegable duty of care' and for the first time seeks to explain all instances of strict liability for the wrongdoing of another in tort in terms of the various relationships in which the courts impose such liability. The thesis shows that, despite appearances, there is a unifying feature to the various relationships in which the courts currently impose strict liability for the wrongdoing of another in tort. That feature is authority. Whenever the courts impose strict liability for the wrongdoing of another in tort, the defendant is either vested with authority over the person who wrongfully harmed the plaintiff or has vested or conferred a form of authority upon that person in respect of the plaintiff. This thesis uses this feature of authority to construct a new expositive framework within which strict liability for the wrongdoing of another in tort can be understood. - provided by Candidate.

description: Many domains are increasingly dominated by interdependent services and data exchange between different actors, leading to the emergence of data ecosystems. As a result, service engineers are increasingly tasked with integrating existing service components and data sources into service systems and orchestrating them. In complex areas such as smart living, these tasks are even more difficult by the particular relevance of individual data protection requirements and the low fault tolerance of security-related systems. To address these issues, a central service registry for the domain smart living has been prototypically developed and evaluated, focusing especially on the transparency of data flows and the technical exchangeability of service components. In this way, added value is achieved for data providers and for data users by providing information on the forwarding of their own data as well as on the origin of the data and possible data quality.

To date, experimental realization of GNFs is only in its infancy because of the limitation of precise cutting or synthesizing methods at the nanometer scale. Here, we use low temperature scanning tunneling microscope (STM) to manipulate coronene molecules on a Cu(111) surface to build artificial triangular and hexagonal GNFs with either zigzag or armchair type of edges. We observe that the metallic edge states only exist in the GNFs with zigzag edge and localize at the most outside one type of the sublattice. The experimental results agree well with the tight-binding calculations. To our knowledge, our work renders the first systematic experimental confirmation of the predicated electronic properties of the GNFs.

description: Secure data exchange between different geographical sites (e.g. industrial manufacturing facilities, power plants, research labs, and manufacturer test facilities) is an important part of cybersecurity. It is for example addressed by section 13 “Communications Security” of ISO/IEC 27002:2013. ISO/IEC 27033-4:2014 gives guidance for securing communications between networks using security gateways (firewall, application firewall, Intrusion Protection System, etc.). While the newest part of the multipart ISO/IEC 27033 standards series, ISO/IEC WD 27033-7 “Information technology Network security Part 7: Guidelines for network virtualization security” is more on the abstraction of physical components involved in communication, this paper aims to emphasize the fiber optical network communication-based security between very specific Cyber-Physical Systems (CPS). In this case, secure means a strictly reduced feedback channel. According to ISO/IEC 27033-4, essentially, the approaches described in this paper would be classified as physically unidirectional security gateways. In this paper, requirements and concepts will be presented which are beneficial for a scalable use in Industry 4.0 applications for highest (hardware-enforced) unidirectional communication and which can coexist with Firewall and Demilitarized Zone (DMZ) approaches that are also needed for complex IACS architectures.

description: Interesting analogies between shallow water dynamics and astrophysical phenomena have offered valuable insight from both the theoretical and experimental point of view. To help organize these efforts, here we analyze systematically the hydrodynamic properties of backwater profiles of the shallow water equations with 2D radial symmetry. In contrast to the more familiar 1D case typical of hydraulics, %already for {even in} isentropic conditions, a solution with minimum-radius horizon for the flow emerges, similar to the black hole and white hole horizons, where the critical conditions of unitary Froude number provide a unidirectional barrier for surface waves. Beyond these time-reversible solutions, a greater variety of cases arises, when allowing for dissipation by turbulent friction and shock waves (i.e., hydraulic jumps) for both convergent and divergent flows. The resulting taxonomy of the base-flow cases may serve as a starting point for a more systematic analysis of higher-order effects linked, e.g., to wave propagation and instabilities, capillarity, variable bed slope, and rotation.
Characterising the distribution of the D2 statistic and its close relatives
Creators: name: Burden, Conrad
Publisher: name: F1000Research
Year: 2015

description: The D2 statistic is defined as the number of k-mer matches for some pre-specified length k between two sequences of letters.  It is potentially a useful statistic for measuring similarity of  DNA or protein sequences in cases where long alignments may not be appropriate.  It is is rarely used directly in its basic form and a number of related statistics with names such as D2z, D2*, D2S and N2 have also been devised.   These related statistics are motivated by a need to give an optimal signal of sequence similarity above the noise of word occurrence variability in each of the sequences, and are often designed to target specific applications.

There are two approaches to designing and using word count statistics.  The most common approach is to build into the statistic allowances for the statistical properties of word counts based on parameters such as sequence lengths and letter distributions, and use the statistic directly as a measure of similarity.  Alternatively, one can take an approach more traditionally aligned with classical statistical hypothesis testing, in which one approximates the distribution of a relatively simple form of the statistic under an assumed null hypothesis, and measures similarity in terms of a calculated P-value.

In this talk I will review advances in the second of these two approaches: How well can we calculate P-values for D2 and its close relatives under null hypotheses of sequences composed of independent letters or sequences with a Markovian dependence.  I will also present results of applying the method to identifying cis-regulatory modules and comparison of the theoretical D2 distribution for Markov sequences up 5th order with empirical distributions of D2 from the human genome.

description: Different societal challenges, such as information overload, emerge due to the digital transformation of the media landscape. This also demands new competencies from citizens that often lack the means to contextualize arguments or actors and to understand their interrelationships in complex topics. The EPINetz project is an approach to bridge the outlined skills gap by developing an appropriate political information system. It provides access to political news collected from multiple data sources, including social media, and offers various network exploration capabilities. Different entities such as political actors or topics are extracted from collected data and shown within their respective contexts modelled as weighted and time-varying information networks. Thereby, interested citizens and especially schoolchildren can discover current political topics and understand relationships between relevant entities.
Firm value, audit quality, and social welfare in the presence of costly litigation against auditors
Creators: name: Pae, Suil
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation has two objectives. The first is to provide a framework for understanding strategic interactions between an auditor and investors in a competitive rational expectations economy. The second is to provide a welfare analysis of auditor litigation in a costly legal environment. We present a model which captures the following aspects: (i) investors in a competitive capital market form rational expectations about their future litigation opportunities against auditors; (ii) auditors compete for potential clients, and they strategically consider the threat of litigation; (iii) the audited firm's production decision depends on audit quality; and (iv) trial is a costly process, and litigants have settlement opportunities. The market price of the firm and audit quality are endogenized. The welfare analysis provides a rationale why society maintains a legal system which provides an incentive for the investors to recover their ex post financial loss from the auditor through a costly legal process, even if they can price-protect themselves ex ante with or without such a mechanism. We interpret the court system as a decentralized disciplinary mechanism for the auditor moral hazard problem, which enables the potential auditee to use an auditor as a commitment device. We examine the economic consequences of legal policies which potentially influence the size of legal costs. When audit failure is clearly defined, an increase in the auditor's legal costs decreases social welfare. An increase in the investors' legal costs has a more complex impact on the actions of economic agents upon which the social costs and benefits of an audit crucially depend. We also study the economic impact of a change from an American to a British rule of allocating legal costs, which was recently proposed by the accounting profession in the U.S. In contrast to the practitioners' common belief, we demonstrate that the British rule might increase the frequency of lawsuit. Therefore, regulators must be very careful in evaluating the accountants' proposal of the British rule, and it should not replace the American rule unless a careful analysis indicates that the net benefit of audits under the British rule is larger than that under the American rule.

description: Article 32 GDPR regulates the obligation to implement appropriate technical and organizational measures whenever personal data is being processed. In this paper, we want to link questions arising from taking appropriate technical and organizational measures with considering the chances and limitations of both, personal and anonymized data processing and the potential added value of personal and anonymized data exchange within a smart city context. We demonstrate the link through a legal analysis and 30 structured interviews with smart city participants.
title: Stimmungen und Qualitätsbewertung im Konferenzdolmetschen
Creators: name: Dyrcz, Judyta
Year: 2023

description: Das Forschungsinteresse der vorliegenden Arbeit ist im didaktischen Setting zu verorten und befasst sich mit der Dolmetschqualität und ihrer Bewertung, wobei der Einfluss von Stimmungen und die Rolle der Expertise beim Evaluieren genauer untersucht wurde. Ausgehend von Qualität als soziales Konstrukt wurde die Variabilität der Beurteilung von Simultandolmetschungen betrachtet, die neben dem situativen Kontext auch von der Bewertungsperspektive abhängt. Dem folgte auch eine Auseinandersetzung mit dem Konzept der Expertise und eine Abgrenzung des Begriffs der Stimmung im Gegensatz zur Emotion. Ausgehend von der FAIT nach Schwarz (2011) und der Arbeit von Behr (2013a) wurde ein empirischer Versuch geplant und am Zentrum für Translationswissenschaft in Wien durchgeführt. Dabei wurde untersucht, welche Unterschiede die Beurteilung durch Studierende von der gleichen Dolmetschaufzeichnung aufweisen und welche Rolle hierbei die Stimmungen spielen. Weiters wurde untersucht, ob sich die Beurteilungen aufgrund der Expertise unterscheiden. Schließlich wurde auch die Benotung einzelner Qualitätsparameter näher beleuchtet. Die Auswertung der erhobenen Daten ergab, dass die Bewertungen der gleichen Verdolmetschung an zwei verschiedenen Versuchsterminen unterschiedlich ausgefallen sind. Dabei wurden im Vergleich zu den inhaltlichen Merkmalen mehr Schwankungen bei der Benotung der kommunikativ-sprachlichen Qualitätsparameter aufgezeigt, wobei vor allem der Aspekt „Prosodie“ betroffen war. Jedoch konnten bei der Betrachtung eines potenziellen Einflusses durch die Stimmungen und die Expertise keine klaren Korrelationen erkannt werden.
