description: The nature of ordering in dilute dipolar interacting systems dates back to the work of Debye and is one of the most basic, oldest and as-of-yet unsettled problems in magnetism. While spin-glass order is readily observed in several RKKY-interacting systems, dipolar spin-glasses are subject of controversy and ongoing scrutiny, e.g., in ${{\rm LiHo_xY_{1-x}F_4}}$, a rare-earth randomly diluted uniaxial (Ising) dipolar system. In particular, it is unclear if the spin-glass phase in these paradigmatic materials persists in the limit of zero concentration or not. We study an effective model of ${{\rm LiHo_xY_{1-x}F_4}}$ using large-scale Monte Carlo simulations that combine parallel tempering with a special cluster algorithm tailored to overcome the numerical difficulties that occur at extreme dilutions. We find a paramagnetic to spin-glass phase transition for all Ho ion concentrations down to the smallest concentration numerically accessible of 0.1%, and including Ho ion concentrations which coincide with those studied experimentally up to 16.7%. Our results suggest that randomly-diluted dipolar Ising systems have a spin-glass phase in the limit of vanishing dipole concentration, with a critical temperature vanishing linearly with concentration, in agreement with mean field theory.

description: We explore the role of exceptional points and complex eigenvalues on the occurrence of the quantum Mpemba effect. To this end, we study a two-level driven dissipative system subjected to an oscillatory electric field and dissipative coupling with the environment. We find that both exceptional points and complex eigenvalues can lead to $multiple$ quantum Mpemba effect. It occurs in an observable when time evolved copies corresponding to two different initial conditions, one initially having higher observable value compared to the other and both relaxing towards the same steady state, intersect each other more than once during their relaxation process. Each of the intersections denotes a quantum Mpemba effect and marks the reversal of identities between the two copies i.e. the copy with higher observable value before the intersection becomes the lower valued copy (and vice versa) after the intersection. Such multiple intersections originate from additional algebraic time dependence at the exceptional points and due to oscillatory relaxation in the case of complex eigenvalues. We provide analytical results for quantum Mpemba effect in the density matrix in presence of coherence. Depending on the control parameters (drive and dissipation), observables such as energy, von Neumann entropy, temperature etc. exhibit either single or multiple quantum Mpemba effect. However, the distance from steady state measured in terms of the Kullback-Leibler divergence shows only single quantum Mpemba effect although the corresponding speed gives rise to either single or multiple quantum Mpemba effect.

description: We investigate time-irreversibility from the point of view of a single particle in Burgers turbulence. Inspired by the recent work for incompressible flows [Xu et al., PNAS 111.21 (2014) 7558], we analyze the evolution of the kinetic energy for fluid markers and use the fluctuations of the instantaneous power as a measure of time irreversibility. For short times, starting from a uniform distribution of markers, we find the scaling $\left\propto t$ and $\left \propto \textrm{Re}^{n-1}$ for the power as a function of the Reynolds number. Both observations can be explained using the "flight-crash" model, suggested by Xu et al. Furthermore, we use a simple model for shocks which reproduces the moments of the energy difference including the pre-factor for $\left$. To complete the single particle picture for Burgers we compute the moments of the Lagrangian velocity difference and show that they are bi-fractal. This arises in a similar manner to the bi-fractality of Eulerian velocity differences. In the above setting time irreversibility is directly manifest as particles eventually end up in shocks. We additionally investigate time irreversibility in the long-time limit when all particles are located inside shocks and the Lagrangian velocity statistics are stationary. We find the same scalings for the power and energy differences as at short times and argue that this is also a consequence of rare "flight-crash" events related to shock collisions.

description: We study how the use of machine-learning based algorithms for the determination of wage offers affects workers’ wages on online labor platforms. Firms use reinforcement-learning to update posted wages on the platform, and heterogeneous workers send applications based on the posted information. We show that if firms use a deep Q-network (DQN), as an example of a state-of-the-art machine learning algorithm, the emerging wages closely resemble the equilibrium outcome. However, slightly changing the setup of the algorithms can lead to substantial collusion and wages well below the equilibrium level. In particular, we identify a specific property of the algorithms, namely whether experience replay is used, which determines whether collusion occurs or not. Our findings are robust with respect to many features of the model, including the design of the online labor platform.

description: We study the thermopower of a three-terminal setup composed of a quantum dot attached to three electrodes, one of which is a topological superconductor. In the model, superconductivity is explicitly taken into account. We compare the results for s-wave (trivial) and p-wave (topological) superconductors and observe that for small temperatures the thermopower has different sign in the two cases. This behavior is strongly dependent on temperature and we estimate an energy scale that controls the sign in the p-wave case, which results proportional to the square root of the gap and the coupling to superconductor. The analytical results obtained with a simple 1D model are confirmed by a more realistic tight-binding model.

description: The safety concerns for autonomous vehicles (AV) is shown a to be roadblock to their adoption. This paper addresses these concerns by studying a unified, game-theoretic framework (leader-follower game) of mixed traffic in which AVs and human-driven vehicles (HV) coexist, with endogenous vehicle demand and different types of accidents emerging in mixed traffic as crucial building blocks. We study the interaction between three types of players: (i) a policymaker, who decides on the liability regime and the level of V2I connectivity infrastructure, (ii) an AV producer, who decides on the AV price and safety level, and (iii) consumers, who differ in their preference for each vehicle type and choose the one they like best. Using both analytical and numerical tools, we analyze how the two policy variables, liability and V2I connectivity, affect behavior on the demand and supply side of the vehicle market and, in turn, AV market penetration and overall road safety. We also characterize optimal policies, thereby taking into account the market participants’ behavioral responses. Our findings provide guidance for a fast adoption ofAVs and a smooth transition from existing traffic conditions to a mixed traffic environment, and assist in decision making for policymakers, legal agencies, traffic operation and transportation planning agencies, as well as car manufacturers.

description: Assistive free-flyer robots autonomously caring for future crewed outposts -- such as NASA's Astrobee robots on the International Space Station (ISS) -- must be able to detect day-to-day interior changes to track inventory, detect and diagnose faults, and monitor the outpost status. This work presents a framework for multi-agent cooperative mapping and change detection to enable robotic maintenance of space outposts. One agent is used to reconstruct a 3D model of the environment from sequences of images and corresponding depth information. Another agent is used to periodically scan the environment for inconsistencies against the 3D model. Change detection is validated after completing the surveys using real image and pose data collected by Astrobee robots in a ground testing environment and from microgravity aboard the ISS. This work outlines the objectives, requirements, and algorithmic modules for the multi-agent reconstruction system, including recommendations for its use by assistive free-flyers aboard future microgravity outposts.

description: In a former paper [Fluct. Noise Lett., 13 (2014) 1450020] we introduced a vehicular communication system with unconditionally secure key exchange based on the Kirchhoff-Law-Johnson-Noise (KLJN) key distribution scheme. In this paper, we address the secure KLJN key donation to vehicles. This KLJN key donation solution is performed lane-by-lane by using roadside key provider equipment embedded in the pavement. A method to compute the lifetime of the KLJN key is also given. This key lifetime depends on the car density and gives an upper limit of the lifetime of the KLJN key for vehicular communication networks.

title: Der Einsatz von BESK(-DaZ) KOMPAKT im Kindergarten
Creators: name: Kabas, Melanie
Year: 2021

description: Seit dem Kindergartenjahr 2019/20 kommt das neu konzipierte Sprachstandserhebungsinstrument BESK(-DaZ) KOMPAKT verpflichtend in allen österreichischen Kindergärten zur Anwendung. Laut dem Bundesministerium für Bildung, Wissenschaft und Forschung sei das Ziel der Anwendung des Instruments, die individuelle Förderung der „Bildungssprache Deutsch“ in Hinblick auf den Schuleintritt zu fokussieren (BMBWF: Sprachförderung ). Das Verfahren gründet auf die vorangegangene Version BESK(-DaZ) 2.0 und bezieht die Forschungsarbeit von Maga. Dr.in Barbara Rössl-Krötzl mit ein. Die Neukonzeption soll einen „ressourcenschonenden“ Einsatz in der elementarpädagogischen Praxis ermöglichen, zugleich die Aussagekraft der Ergebnisse gewährleisten. Vorgegebene Beobachtungszeiträume und Schwellenwerte des Verfahrens, die einen „Förderbedarf“ festlegen, sollen der einheitlichen Erhebung dienen (vgl. Rössl-Krötzl & Breit, 2018, S. 5; Rössl-Krötzl & Breit 2019, S. 5). Es kann festgehalten werden, dass einerseits bildungspolitische Motive mit dem vorgegebenen Instrument verfolgt werden, andererseits soll das Verfahren der Sprachförderung der Kindergartenpraxis dienlich sein (BMBWF: Sprachförderung ). Insofern hat sich diese Arbeit zum Ziel gesetzt, die Möglichkeiten und Grenzen von Sprachstandserhebungsverfahren aufzuzeigen, Möglichkeiten der Sprachförderung im elementarpädagogischen Bereich zu ergründen und gezielt dahingehend das neue Beobachtungsverfahren näher zu betrachten. Um nicht nur eine theoretische Perspektive auf die genannten Thematiken zu erhalten, wurden mittels eines qualitativen Verfahrens (Leitfadeninterviews) vier Kindergartenleiterinnen und acht Kindergartenpädagog*innen im Raum Wien befragt. Damit wurde ein Einblick in die elementarpädagogische Praxis der Wiener Kindergärten (Träger: Wiener Kinderfreunde) und in die Lebenswelt der tätigen Pädagog*innen ermöglicht. In der angegebenen Reichweite der Erhebung kann festgehalten werden, dass das Instrument aufgrund seiner Einfachheit und Praktikabilität durchwegs positiv von den Pädagog*innen bewertet wird. Dennoch zeigt sich, dass das Instrument umfassender und differenzierter hinsichtlich der Erhebung des Sprachstandes sein könnte. Es wurde festgestellt, dass die Anwendung des Instruments vor allem von personellen Ressourcen, aber auch von der Organisation im Team abhängig ist. Hinsichtlich der gewonnenen Ergebnisse führen die Pädagog*innen an, dass das Instrument kaum eine Rolle in Bezug auf die eigene pädagogische Planung oder der Führung von Elterngesprächen spielt. Der festgestellte Förderbedarf gemäß dem Instrument erhält unterschiedliche Relevanz, und damit auch keine eindeutige Rolle oder Funktion, innerhalb der pädagogischen Praxis. Resultierend aus den gewonnenen Ergebnissen kann in Frage gestellt werden, ob das verpflichtende „förderdiagnostische“ Sprachstandserhebungsinstrument tatsächlich der umgesetzten Sprachförderung in der Praxis dienlich ist.

description: Transport properties of a charged droplet of weakly interacting particles in an external field are investigated. A non-equilibrium distribution function which describes a process of the droplet transverse evolution with constant entropy in an external electric field is calculated. With the help of this distribution function, shear viscosity coefficients in the transverse plane are calculated as well. They are found to be very small and depend on the time of the droplet's expansion in a hydrodynamical regime and external field value. An applicability of the results to the description of initial states of quark-gluon plasma obtained in high-energy interactions of nuclei is also discussed.

description: We obtain the rate function for the level 2.5 of large deviations for pure jump and diffusion processes. This result is proved by two methods: tilting, for which a tilted process with an appropriate typical behavior is considered, and a spectral method, for which the scaled cumulant generating function is used. We also briefly discuss fluctuation relations, pointing out their connection with large deviations at the level 2.5.

description: Dioptas is a widely used software package for integrating and analysing 2-dimensional diffraction images. To help interpret the integrated diffraction profiles it produces, Dioptas users can input files that parameterise a material's thermal equation of state (EoS), enabling the positions of the Bragg peaks from that material to be calculated as a function of pressure and temperature. However, care is needed to ensure that these input files correctly describe the thermal EoS of interest. Here we describe the thermal EoS model used by Dioptas and show how existing thermal EoS should be reparameterised so as to be used correctly in Dioptas. Input EoS files suitable for use with Dioptas are provided for the following commonly-used pressure calibrants and pressure transmitting media: Al, Au, Cu, Mo, Nb, Pt, Ta, hcp-Fe, MgO, NaCl-B1, NaCl-B2, KCl-B2, and Ne.

description: We investigate a time harmonic acoustic scattering problem by a penetrable inclusion with compact support embedded in the free space. We consider cases where an observer can produce incident plane waves and measure the far field pattern of the resulting scattered field only in a finite set of directions. In this context, we say that a wavenumber is a non-scattering wavenumber if the associated relative scattering matrix has a non trivial kernel. Under certain assumptions on the physical coefficients of the inclusion, we show that the non-scattering wavenumbers form a (possibly empty) discrete set. Then, in a second step, for a given real wavenumber and a given domain D, we present a constructive technique to prove that there exist inclusions supported in D for which the corresponding relative scattering matrix is null. These inclusions have the important property to be impossible to detect from far field measurements. The approach leads to a numerical algorithm which is described at the end of the paper and which allows to provide examples of (approximated) invisible inclusions.

description: We study scattering of a periodic wave in a string on two lumped oscillators attached to it. The equations can be represented as a driven (by the incident wave) dissipative (due to radiation losses) system of delay differential equations of neutral type. Nonlinearity of oscillators makes the scattering non-reciprocal: the same wave is transmitted differently in two directions. Periodic regimes of scattering are analysed approximately, using amplitude equation approach. We show that this setup can act as a nonreciprocal modulator via Hopf bifurcations of the steady solutions. Numerical simulations of the full system reveal nontrivial regimes of quasiperiodic and chaotic scattering. Moreover, a regime of a "chaotic diode", where transmission is periodic in one direction and chaotic in the opposite one, is reported.

description: We study the properties of a quantum particle interacting with a one dimensional structure of equidistant scattering centres. We derive an analytical expression for the dispersion relation and for the Bloch functions in the presence of both even and odd scattering waves within the pseudopotential approximation. This generalises the well-known solid-state physics text-book result known as the Kronig-Penney model. Our generalised model can be used to describe systems such as degenerate Fermi gases interacting with ions or with another neutral atomic species confined in an optical lattice, thus enabling the investigation of polaron or Kondo physics within a simple formalism. We focus our attention on the specific atom-ion system and compare our findings with quantum defect theory. Excellent agreement is obtained within the regime of validity of the pseudopotential approximation. This enables us to derive a Bose-Hubbard Hamiltonian for a degenerate quantum Bose gas in a linear chain of ions.

description: The equipartition theorem is crucial in classical statistical physics, and recent studies have revealed its quantum counterpart for specific systems. This raises the question: does a quantum counterpart of the equipartition theorem exist for any given system, and if so, what is its concrete form? In this Letter, we employ the Möbius inversion approach to address these questions, providing a criterion to determine whether a system adheres to the quantum counterpart of the equipartition theorem. If it does, the corresponding distribution function can be readily derived. Furthermore, we construct the fermionic version of the criterion in a manner analogous to the bosonic case.

description: Dans l’objectif de mieux caractériser le devenir en mer des apports terrigènes autour de la ville de Nouméa, Nouvelle-Calédonie, notamment suite au passage de dépressions et cyclones tropicaux, différents réseaux d’observation routiniers (GOPS, Météo-France, DAVAR) ont été complétés par l’installation d’instruments au niveau des exutoires marins de la Dumbéa et la Coulée, et par la réalisation répétée de profils hydrologiques (CTD) sur la zone côtière d’intérêt. L’objectif de ce rapport est de restituer et commenter les observations collectées. Le contexte météo-océanique et les observations réalisées sont d’abord exposés sur l’ensemble de la période étudiée, qui court du 1er décembre 2016 au 30 avril 2017. Les conséquences du passage du cyclone Cook sur les paramètres physico-chimiques du lagon sont ensuite décrites pour la période du 10 au 19 avril 2017. Les surcotes, les vagues, la température, la salinité et la turbidité sont présentées en particulier, en différents endroits du lagon, et mises en relation avec les paramètres atmosphériques (pression, vent, précipitations) et hydrologiques (débits des rivières). Sur toute la période d’étude, les vagues et les surcotes observées sont restées d’amplitude modérée. L’impact des dépressions sur la température a été relativement faible et localisé proche des côtes alors que la salinité et la turbidité ont évolué rapidement sous leur action, même sur des zones situées relativement au large des côtes. Ces résultats suggèrent que les phénomènes dépressionnaires, et particulièrement les cyclones, sont susceptibles de modifier substantiellement les masses d’eaux lagonaires bien au-delà des zones impactées par les apports terrigènes par temps calme

title: Dekonstruktion in der sexuellen Bildung
Creators: name: Reinhardt, Diana
Year: 2021

description: Die vorliegende Masterarbeit beschäftigt sich mit dem Themenfeld der Dekonstruktion in der Sexuellen Bildung. Den Beginn der Auseinandersetzung markiert die Reflexion über die Methode der sogenannten Geschlechtertrennung in sexualpädagogischen Workshops. Dabei wird mit Jungen und Mädchen separat zu ausgewählten Themen gearbeitet. Diese Methode ist eine nach wie vor gängige Praxis, welche sowohl Nachteile als auch Vorteile hat. Von diesem Dilemma ausgehend wird anhand von Expert_inneninterviews mit Personen, die in unterschiedlichen Felder der Sexuellen Bildung in Österreich tätig sind, der Frage nach dekonstruktiven Ansätzen in ihrer Arbeit nachgegangen. Dabei geht es besonders um den Einfluss und die Relevanz poststrukturalistisch-dekonstruktiver Perspektiven auf die praktische Arbeit und die Haltung der befragten Expert_innen. Die Interviews werden angeführt von einer theoretischen Annäherung an die Dekonstruktion an sich und ihrer Anwendung in (sexual)pädagogischen Kontexten. Ganz im Sinne des Impetus der Dekonstruktion stellt die vorliegende Arbeit eine Auseinandersetzung dar, ohne abschließende Ergebnisse festzulegen.
description: This master thesis deals with the topic of deconstruction in the field of sexual education. The reflection on the method of the so-called gender separation in sexual education workshops marks the beginning of the following examination. Gender separation in sexual education involves working with boys and girls separately on selected topics. This method is still common practice and has both disadvantages and advantages. Starting from this dilemma, the question of deconstructive approaches in their work will be investigated by means of interviews with experts working in different fields of sexual education in Austria. The focus is on the influence and relevance of poststructuralist deconstructive perspectives on the practical work and the attitude of the interviewed experts. The interviews are led by a theoretical approach to deconstruction itself and its application in (sexual) pedagogical contexts. In line with the impetus of deconstruction, the present work represents an examination without determining conclusive results.

description: In theory, quantum key distribution (QKD) provides information-theoretic security based on the laws of physics. Owing to the imperfections of real-life implementations, however, there is a big gap between the theory and practice of QKD, which has been recently exploited by several quantum hacking activities. To fill this gap, a novel approach, called measurement-device-independent QKD (mdiQKD), has been proposed. It can remove all side-channels from the measurement unit, arguably the most vulnerable part in QKD systems, thus offering a clear avenue towards secure QKD realisations. Here, we review the latest developments in the framework of mdiQKD, together with its assumptions, strengths and weaknesses.

description: L’huitre plate native des côtes européennes, est une espèce emblématique de Bretagne. Convoitée depuis l'Antiquité, sur-pêchée au 19ème siècle, fleuron de l'ostréiculture au 20ème, elle est désormais menacée de disparition à l'aube du 21ème. Sous l'impulsion de la commission OSPAR mais aussi dans un contexte grandissant de crise écologique et d'érosion de la biodiversité imposant une nécessaire conservation et/ou restauration de nos patrimoines naturels, une alliance européenne réunissant biologistes et gestionnaires a été créée en novembre 2017 à Berlin sous l'égide de l'Agence Allemande de Conservation de la Nature (BFN) avec un seul objectif : favoriser le retour de l'huitre plate sur les côtes. Cette alliance européenne pour la restauration de l'huitre plate (NORA) regroupe désormais plus d'une centaine de scientifiques et de gestionnaires, tous au chevet de cette espèce. En France, cette démarche est assurée par le programme FOREVER ("Flat Oyster Recovery"), démarré en 2018 et financé par le FEAMP pour sa première phase (2018-2020). Le présent rapport fait état de l'avancement du projet. Au bout d'un an, le programme FOREVER a permis : (1) de construire les bases et la méthodologie permettant d'assurer un inventaire le plus précis possible des dernières populations relictuelles d'huitres plates encore présentes en Bretagne; (2) d'étudier plus précisément les mécanismes écologiques impliqués dans la dynamique d'un banc d'huitres plates : abondance et dispersion larvaire, dynamique du recrutement, facteurs environnementaux, effet de la prédation, impact des maladies parasitaires. L'ensemble de ces processus est étudié à la fois en rade de Brest et en baie de Quiberon et (3) d'initier une démarche unique en France permettant la conservation et la restauration écologique des derniers bancs. Cette démarche inclue des opérations de communication et de sensibilisation actives associées à des actions pilotes concrètes et facilement transférables de restauration écologique : enrichissement coquillier, semis de naissain et développement de récifs artificiels adaptés à l'espèce.

description: We study the photoproduction of the heavy quarkonium at the future International Linear Collider (ILC) within the nonrelativistic QCD theory. We focus on the production channel via the subprocess $γγ\to |[Q\bar{Q'}]_{\bf 1}(n)>+Q'+\bar{Q}$, where $Q$ and $Q'$ stand for heavy $c$- or $b$-quark, respectively. $|[Q\bar{Q'}]_{\bf 1}(n)>$ stands for color-singlet $S$-wave quarkonium, i.e., $η_{c}(|[c\bar{c}]_{\bf 1}(^1S_0)>)$, $J/ψ(|[c\bar{c}]_{\bf 1}(^3S_1)>)$, $B_{c}(|[c\bar{b}]_{\bf 1}(^1S_0)>)$, $B^*_{c}(|[c\bar{b}]_{\bf 1}(^3S_1)>)$, $η_{b}(|[b\bar{b}]_{\bf 1}(^1S_0)>)$, and $Υ(|[b\bar{b}]_{\bf 1}(^3S_1)>)$, respectively. To improve the calculation efficiency, we adopt the improved helicity amplitude approach to deal with the difficulty of calculating the expressions for the yields when the quark masses cannot be neglected. Total and differential photoproduction cross sections, together with their uncertainties, have been presented. It is noted that sizable amount of $|c\bar{c}>$-charmonium and $|c\bar{b}>$-quarkonium events can be generated at the ILC. More specifically, we predict $(2.8^{+1.0}_{-0.7})\times 10^{6}$ $η_c$, $(5.4^{+1.9}_{-1.3})\times 10^{6}$ $J/ψ$, $(8.3^{+2.2}_{-1.8})\times 10^{4}$ $B_c$, $(4.3^{+1.1}_{-0.9})\times 10^{5}$ $B_c^*$, $(9.0^{+1.7}_{-1.4})\times 10^{3}$ $η_b$, and $(1.6\pm0.3)\times 10^{4}$ $Υ$ events to be generated in one operation year at the ILC under the condition of $\sqrt{S}=500$ GeV and ${\cal L}\simeq 10^{36}$cm$^{-2}$s$^{-1}$.

description: Time-lapse images carry out important information about dynamic changes in Earth's interior which can be inferred using different Full Waveform Inversion (FWI) schemes. The estimation process is performed by manipulating more than one seismic dataset, associated with the baseline and monitors surveys. The time-lapse variations can be so minute and localised that quantifying the uncertainties becomes fundamental to assessing the reliability of the results. The Bayesian formulation of the FWI problem naturally provides confidence levels in the solution, but evaluating the uncertainty of time-lapse seismic inversion remains a challenge due to the ill-posedness and high dimensionality of the problem. The Hamiltonian Monte Carlo (HMC) can be used to effectively sample over high dimensional distributions with affordable computational efforts. In this context, we propose a probabilistic Bayesian sequential approach for time-lapse FWI using the HMC method. Our approach relies on the integration of the baseline survey information as prior knowledge in the monitor estimation. We compare the proposed methodology with a parallel scheme in perfect and perturbed acquisition geometry scenarios. We also investigate the correlation effect between baseline and monitor samples in the propagated uncertainties. The results show that our strategy provides accurate times-lapse estimates with errors of similar magnitude to the parallel methodology.

[Re]constructing Finite Flavour Groups: Horizontal Symmetry Scans from the Bottom-Up
Creators: name: Talbert, Jim

Year: 2014
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present a novel procedure for identifying discrete, leptonic flavour symmetries, given a class of unitary mixing matrices. By creating explicit 3D representations for generators of residual symmetries in both the charged lepton and neutrino sector, we reconstruct large(r) non-abelian flavour groups using the GAP language for computational finite algebra. We use experimental data to construct only those generators that yield acceptable (or preferable) mixing patterns. Such an approach is advantageous because it 1) can reproduce known groups from other 'top-down' scans while elucidating their origins from residuals, 2) find new previously unconsidered groups, and 3) serve as a powerful model building tool for theorists wishing to explore exotic flavour scenarios. We test our procedure on a generalization of the canonical tri-bimaximal (TBM) form.

title: Zur Wahrnehmung von Standardvarietät durch deutschsprachige Südtirolerinnen und Südtiroler
Creators: name: Hlawka, Elena
Year: 2021

description: Die Arbeit beschäftigt sich mit den Standardvarietäten der deutschen Sprache. Gegenstand der empirischen Untersuchung ist die Perzeption der Standardvarietäten der drei Vollzentren der deutschen Sprache, Deutschland, Österreich und der Schweiz, sowie der Südtiroler Standardvarietät durch deutschsprachige Südtiroler*innen. Der theoretische Teil der Arbeit setzt sich mit der Konzeptualisierung der deutschen Standardvarietäten, die sprachliche Asymmetrie der Varietäten sowie die sprachliche Situation in Südtirol in Bezug auf sprachhistorische Gegebenheiten, die innere und äußere Mehrsprachigkeit, Sprachnormautoritäten und Spracheinstellungen auseinander. Neben den theoretischen Ausführungen wurde anhand eines Hörerurteilstest eruiert, wie deutschsprachige Südtiroler*innen die Sprechweisen der Standardvarietäten nach Eigenschaftspaaren bewerten, ob sie die Herkunft der jeweiligen Sprecher*innen erkennen und ob sie das Gesprochene als reines Hochdeutsch beurteilen. Dafür wurden den Proband*innen 16 Sprachproben von geschulten Mediensprecher*innen aus Südtirol, Deutschland, Österreich und der Schweiz präsentiert. Aus der Analyse der Ergebnisse geht hervor, dass deutschsprachige Südtiroler*innen die bundesdeutsche Standardvarietät am eindeutigsten zuordnen können. Die Sprechweise der bundesdeutschen Mediensprecher*innen wird sowohl als reinstes Hochdeutsch bewertet als auch in allen Eigenschaftspaaren am besten beurteilt. Die Sprachproben aus Südtirol und Österreich wurden hinsichtlich der Korrektheit und Kompetenz ähnlich bewertet, wobei die Proband*innen ihre eigene Standardvarietät als am künstlichsten empfinden. Bei der Bewertung der dialektalen Färbung wurde lediglich die bundesdeutsche Standardvarietät als relativ frei von Dialektfärbung bewertet, während die Schweizer Standardvarietät von der Mehrheit der Pro- band*innen als dialektgefärbt empfunden wird. Es konnte dabei festgestellt werden, dass ein Zusammenhang zwischen der Bewertung der Dialektfärbung und der Bewertung der Sprechweise in gebildet oder ungebildet besteht.
