title: Zwischen Trend und Nische: die Kreislaufwirtschaft in der Wiener Baubranche
Creators: name: Schabetsberger, Monika
Year: 2022

description: Innerhalb dieser Masterarbeit wird die Kreislaufwirtschaft in der Wiener Baubranche näher untersucht. Am Beginn wird das Prinzip einer Kreislaufwirtschaft erklärt und anschließend der theoretisch-konzeptionelle Rahmen rund um die Multi-Level Perspektive und um die Transition Management Theorie gelegt. Um aktuelle Erkenntnisse zu diesem Thema einarbeiten zu können, wurden drei Interviews mit Vertreter*innen der Stadt Wien sowie aus dem Nischen-Bereich durchgeführt und Dokumente der Stadt Wien analysiert. Ziel dieser Arbeit ist es, die derzeitige Situation in Wien in Hinsicht auf die Kreislaufwirtschaft in der Baubranche darzulegen. Hierbei wird geprüft, welche Ansätze und strategischen Faktoren die Stadt Wien dafür verfolgt, welche Akteur*innen sie miteinbezieht und welche Herausforderungen bestehen. Ein Perspektivenwechsel wird angestrebt, indem auch die Nischen-Akteur*innen, „BauKarussell“ und „materialnomaden“ zu diesem Thema befragt werden. Diesbezüglich wird geprüft, welche Anreize und Herausforderungen für sie in Wien bestehen und wie eine etwaige Zusammenarbeit mit der Stadt Wien wahrgenommen wird. Am Ende dieser Arbeit zeigt sich, dass das die Kreislaufwirtschaft in der Baubranche ein einerseits aufstrebendes, sowie vielversprechendes Thema ist, andererseits aber noch eine Nische darstellt und vor Herausforderungen steht. Eine mögliche Zusammenarbeit, um die Kreislaufwirtschaft in der Wiener Baubranche zu etablieren, wird von allen interviewten Beteiligten geschätzt.
description: This master’s thesis explores the circular economy in the construction sector in Vienna. At the beginning, the principles of a circular economy are explained and the concepts concerning a multi-level perspective and transition management are presented. For gaining an overview of the current affairs regarding this topic, three interviews are conducted with one representative of the city of Vienna as well as two niche actors. Furthermore, documents mainly published by the Vienna Municipal Administration are analyzed. The goal of this thesis is to present the current situation concerning the development of a circular economy in the Viennese construction sector. Hence, the approaches and strategic factors of the city council are examined. Gaining insight into which actors are involved in developing this economy and which possible difficulties exist, is another major focus. For a change of perspective, the niche actors, “BauKarussell” and “materialnomaden”, are also interviewed. In this respect, the question is which incentives and difficulties Vienna offers with regard to a future circular construction sector. It is examined how BauKarussell and materialnomaden assess a possible collaboration with the city of Vienna. At the end of this thesis, it is shown that the circular construction industry in Vienna is a flourishing and promising topic, yet, it is still a niche and difficulties exist. A collaboration between the city and these niche actors is appreciated by every interviewee.

description: Named entity recognition (NER) is usually developed and tested on text from well-written sources. However, in intelligent voice assistants, where NER is an important component, input to NER may be noisy because of user or speech recognition error. In applications, entity labels may change frequently, and non-textual properties like topicality or popularity may be needed to choose among alternatives. We describe a NER system intended to address these problems. We test and train this system on a proprietary user-derived dataset. We compare with a baseline text-only NER system; the baseline enhanced with external gazetteers; and the baseline enhanced with the search and indirect labelling techniques we describe below. The final configuration gives around 6% reduction in NER error rate. We also show that this technique improves related tasks, such as semantic parsing, with an improvement of up to 5% in error rate.

description: This paper develops a glocal (global-local) attack detection framework to detect stealthy cyber-physical attacks, namely covert attack and zero-dynamics attack, against a class of multi-agent control systems seeking average consensus. The detection structure consists of a global (central) observer and local observers for the multi-agent system partitioned into clusters. The proposed structure addresses the scalability of the approach and the privacy preservation of the multi-agent system's state information. The former is addressed by using decentralized local observers, and the latter is achieved by imposing unobservability conditions at the global level. Also, the communication graph model is subject to topology switching, triggered by local observers, allowing for the detection of stealthy attacks by the global observer. Theoretical conditions are derived for detectability of the stealthy attacks using the proposed detection framework. Finally, a numerical simulation is provided to validate the theoretical findings.

description: Coherent state photon sources are widely used in quantum information processing. In many applications, such as quantum key distribution (QKD), a coherent state is functioned as a mixture of Fock states by assuming its phase is continuously randomized. In practice, such a crucial assumption is often not satisfied and, therefore, the security of existing QKD experiments is not guaranteed. To bridge this gap, we provide a rigorous security proof of QKD with discrete-phase-randomized coherent state sources. Our results show that the performance of the discrete-phase randomization case is close to its continuous counterpart with only a small number (say, 10) of discrete phases. Comparing to the conventional continuous phase randomization case, where an infinite amount of random bits are required, our result shows that only a small amount (say, 4 bits) of randomness is needed.

title: Free will in an Arab human rights context
Creators: name: Thurner, Gabriel
Year: 2022

description: Die vorliegende Masterarbeit befasst sich mit der Frage, inwieweit die beiden Menschenrechte `Religionsfreiheit´ und `Gleichheit der Geschlechter´ im arabischen Raum menschenrechtlich verankert und mit internationalen Menschenrechtsquellen vereinbar sind. Nach einer sowohl in geographischer Hinsicht (Staaten der Arab League) sowie in Bezug auf die Quellen (ICCPR, CEDAW, ACHR, etc) vorgenommenen Eingrenzung und einer kurzen Einführung in das arabische Rechtssystem der Sharia bzw des islamischen Rechts, erfolgt eine Darstellung einzelner relevanter nationaler Rechtsquellen sowie der derzeit in den gegenständlichen Ländern feststellbaren Menschenrechtssituation im Hinblick auf die beiden genannten Rechte. Die Untersuchung gelangt zur Feststellung, dass die arabischen/regionalen Menschenrechts-quellen in teils krassem Widerspruch zu internationalen Menschenrechtsquellen stehen, aber auch innerhalb der arabischen Quellen erhebliche Inkonsistenzen und Widersprüche bestehen, deren Wurzeln nicht zuletzt im insgesamt inkohärenten Rechtssystem der Sharia zu suchen sind. Reformen werden als notwendig erkannt, allerdings sind realistisch betrachtet adäquate Schritte in Richtung einer Modernisierung des arabischen Menschenrechtsschutzes in gegen-ständlichem Themenbereich in nächster Zeit nicht zu erwarten.
description: The present master thesis deals with the question as to how, and to which extent, the human rights `religious freedom´ and `gender equality´ are stipulated in the Arab world and whether relevant Arab human rights sources are compatible with International Human Rights Law (IHRL). After a geographic delineation (states of the Arab League) and a clarification in regard to international and regional legal sources (ICCPR, CEDAW, ACHR, etc), a short introduction into the legal system of the Sharia and Islamic Law is given, followed by an analysis of relevant national laws and the human rights situation on the ground with respect to both said rights. The thesis concludes that there are several inconsistencies and incompatibilities between IHRL and Arab human rights sources, and that such incompatibilities also do exist within Arab sources, the roots of which are partly to be found in the incoherent legal Sharia system. Reforms are deemed necessary, however, realistically, adequate steps towards a modernization of the Arab human rights protection system in the context of gender equality and religious freedom cannot be expected anytime soon.

Furthermore, we give examples of compact sets in the Euclidean unit cube, that have almost any other compact set of the cube as a tangent at all points or just in a dense sub-set. Here the "almost all compact sets" means that the tangent collection contains a contracted image of any compact set of the cube and that the contraction ratios are uniformly bounded. In the Euclidean space, the distance of sub-sets is measured by the Hausdorff distance. Also the geometric properties and dimensions of such spaces and sets are studied.

description: Die vorliegende Arbeit untersucht das Verhalten der ÖsterreicherInnen rund um Nahrungsergänzungsmittel. Es wurden Einnahmeverhalten, Einkaufsverhalten, sowie Meinungen und Einnahmegründe von Nahrungsergänzungsmitteln und Nahrungsergänzungsmittelpräparaten von 532 ÖsterreicherInnen mittels Online-Fragebogen erhoben. Diese Erhebung wird im nächsten Schritt analysiert und in Beziehung zu diversen sozioökonomischen Parametern, sowie dem Sport- und Ernährungsverhalten gesetzt und ausgewertet. Abschließend werden die Ergebnisse präsentiert. Auffällig ist, dass mit zunehmendem Alter die Häufigkeit der Verwendung von Supplementen, sowie die Anzahl der unterschiedlich konsumierten Nahrungsergänzungsmittelpräparate zugenommen hat. Weiters war ein positiver Zusammenhang zwischen erhöhter sportlicher Tätigkeit und gesunder Ernährung mit einer erhöhten Einnahme von Nahrungsergänzungsmitteln zu verzeichnen. Außerdem hat der Großteil der Befragten angegeben, drei bis vier unterschiedliche Präparate einzunehmen und auch täglich welche zu konsumieren. Um detaillierte Aussagen treffen zu können, die für den Durchschnittsösterreicher, sowie für die Durchschnittsösterreicherin valide sind, sind weitere Studien unbedingt notwendig.
description: This study investigates the behavior of Austrians with regard to dietary supplements. Intake behavior, purchasing behavior, as well as opinions and reasons for taking dietary supplements and dietary supplement preparations of 532 Austrians were surveyed by means of an online questionnaire. In the next step, this survey is analyzed and evaluated in relation to various socioeconomic parameters, as well as sports and nutritional behavior. Finally, the results are presented. It is noticeable that with increasing age, the frequency of the use of supplements, as well as the number of differently consumed dietary supplement preparations supplements increased. Furthermore, there was a positive correlation between increased sporting activity and a healthy diet with an increased intake of dietary supplements. In addition, the majority of respondents stated that they took three to four different supplements and also consumed some on a daily basis. In order to be able to make detailed statements that are valid for the average Austrian, further studies are absolutely necessary.

The factorization recipe is shown to be a more reliable approximation and is used to obtain the ro-vibrational energies for the lithium dimer. For each vibrational state only a limited number of the rotational levels are found to be supported by the lithium dimer.

On the rate of convergence of the rescaled mean curvature flow and other geometric problems
Creators: name: Martin-Hagemeyer, Rory
Publisher: name: No Publisher Supplied
Year: 2022

description: In this thesis, we present two results from fields situated at two different extremities of the broader subject of (semi)-Riemannian geometry: mean curvature flow, and the investigation of algebraic properties of curvature tensors and their derivatives. First, in the field of mean curvature flow, I show that the rate of convergence of any solution to rescaled mean curvature flow which is not a shrinker moving by diffeomorphisms is at most some fixed exponential rate. We prove this by defining a new flow, the normal rescaled mean curvature flow, which is equivalent up to tangential diffeomorphisms to the rescaled mean curvature flow. In this new flow, evolution equations are very easy to compute as it has no tangential component. We calculate the evolution equations of key geometric quantities in this new flow and use the calculations to define a suitable energy functional and compute its evolution equations. With these evolution equations, we define a Dirichlet Einstein quotient and prove its boundedness for all time. Next, we show that the standard representation of GL(n) on the space of algebraic covariant derivative curvature tensors is faithful. This theorem was part of a 2018 paper joint with Corey Dunn and Darrien Elderfield in which it was also shown that the standard representation of $GL(n)$ on the space of algebraic curvature tensors is almost faithful, with Kernel ±I. Both results are proven via the Jordan normal form, we shall give a full proof of the former result.

title: Höflichkeit und Unhöflichkeit
Creators: name: Werner, Elisabeth
Year: 2022

description: Die vorliegende Arbeit untersucht mögliche Unterschiede hinsichtlich des Empfindens von Höflichkeit und Unhöflichkeit des Sprechakts „Aufforderung“ in gesprochenen Situationen und geschriebenen Texten. Dazu werden zunächst relevante sprachwissenschaftliche Theorien zu verbaler Höflichkeit und Unhöflichkeit vorgestellt, insbesondere die Sprechakttheorien von Austin und Searle, die Konversationsmaximen von Grice und das Höflichkeitsmodell von Brown und Levinson sowie Culpepers Theorie zur Unhöflichkeit. Anschließend werden die grammatischen Dimensionen der deutschen Sprache, die für höfliche Sprachverwendung relevant sind, näher erörtert. Für diese Arbeit wurde eine Fragebogenuntersuchung als Methode der quantitativen Datenerhebung durchgeführt. Als Zielgruppe dienen aktuelle und ehemalige weibliche und männliche Studierende der Sprachwissenschaft an der Fakultät für Germanistik der Universität Wien. Den Untersuchungskorpus für die Studie bilden die Beantwortung der Fragebögen von insgesamt 20 Teilnehmern und Teilnehmerinnen. Im Analyseteil werden zunächst die Ergebnisse für jede der neun Aufforderungssituationen und drei Aufforderungstexte ausgewertet und interpretiert und in Diagrammen dargestellt. Die Studie wird abgeschlossen mit der Interpretation der Analyse der Daten nach den drei Merkmalen Geschlecht, Alter und höchste Ausbildungsstufe und ihr Zusammenfügen zu Ergebnissen, in der die Hypothesen geprüft werden.
description: This paper examines possible differences in the perception of politeness and impoliteness of the speech act "request" in spoken situations and written texts. To this end, relevant linguistic theories on verbal politeness and impoliteness are first presented, in particular the speech act theories of Austin and Searle, the conversational maxims of Grice and the politeness model of Brown and Levinson, as well as Culpeper's theory on impoliteness. The grammatical dimensions of the German language relevant to polite language use are then discussed in more detail. For this thesis, a questionnaire survey was conducted as a method of quantitative data collection. Current and former female and male students of linguistics at the Faculty of German Studies at the University of Vienna serve as the target group. The research corpus for the study is formed by the responses to the questionnaires of a total of 20 male and female participants. In the analysis section, the results for each of the nine request situations and three request texts are first evaluated and interpreted and presented in diagrams. The study is concluded with the interpretation of the analysis of the data according to the three characteristics of gender, age and highest level of education and their combination into results, in which the hypotheses are tested.

description: The quantitative description of cultural evolution is a challenging task. The most difficult part of the problem is probably to find the appropriate measurable quantities that can make more quantitative such evasive concepts as, for example, dynamics of cultural movements, behavior patterns and traditions of the people. A strategy to tackle this issue is to observe particular features of human activities, i.e. cultural traits, such as names given to newborns. We study the names of babies born in the United States of America from 1910 to 2012. Our analysis shows that groups of different correlated states naturally emerge in different epochs, and we are able to follow and decrypt their evolution. While these groups of states are stable across many decades, a sudden reorganization occurs in the last part of the twentieth century. We think that this kind of quantitative analysis can be possibly extended to other cultural traits: although databases covering more than one century (as the one we used) are rare, the cultural evolution on shorter time scales can be studied thanks to the fact that many human activities are usually recorded in the present digital era.

title: Grenzen überwinden: warum gehört Globalgeschichte in den Unterricht?
Creators: name: Papenheim, Seline
Year: 2022

description: Die Ansicht, dass historische und politische Ereignisse nicht innerhalb von europäischen oder nationalstaatlichen Grenzen verstanden werden können, sondern Wissen über Zusammenhänge, Beziehungen und Voraussetzungen über diese Grenzen hinaus notwendig ist, wird beispielsweise von Vertreter*innen der Globalgeschichte argumentiert. Globalgeschichte steht dabei im Gegensatz zu Eurozentrismus und Nationalgeschichte. In den Curricula für den Unterricht des Schulfaches Geschichte, Sozialkunde und Politische Bildung (GSP) kann - wenngleich globalgeschichtliche Perspektiven auch vorhanden sind – nach wie vor eine eurozentrische Präferenz erkannt werden. Diese eurozentrische Tendenz ist in direktem Widerspruch zum Prinzip des Lebensweltbezugs, da durch migrationsbedingte Diversität sich die Lebenswelten der Schüler*innen kaum auf einen Kontinent beschränken können. Ziel dieser Arbeit ist der Entwurf eines didaktischen Modells, welches eine Hilfestellung für Lehrpersonen, welche globalgeschichtliche Fragestellungen in ihrem GSP-Unterricht behandeln wollen, darstellen soll. Zuvor wird ausführlich die Problematik, die Eurozentrismus im GSP-Unterricht darstellt, erklärt und durch eine Umfrage werden Meinungen von Schüler*innen zu dem Thema erhoben. Der eigentlichen Modellentwicklung folgen Umsetzungsmöglichkeiten anhand des historischen und politischen Ereignisses des Syrienkonflikts.

description: We establish the capacity of a class of communication channels introduced in [1]. The $n$-letter input from a finite alphabet is passed through a discrete memoryless channel $P_{Z|X}$ and then the output $n$-letter sequence is uniformly permuted. We show that the maximal communication rate (normalized by $\log n$) equals $1/2 (rank(P_{Z|X})-1)$ whenever $P_{Z|X}$ is strictly positive. This is done by establishing a converse bound matching the achievability of [1]. The two main ingredients of our proof are (1) a sharp bound on the entropy of a uniformly sampled vector from a type class and observed through a DMC; and (2) the covering $ε$-net of a probability simplex with Kullback-Leibler divergence as a metric. In addition to strictly positive DMC we also find the noisy permutation capacity for $q$-ary erasure channels, the Z-channel and others.

Spectral approach to axisymmetric evolution of Einstein's equations

Publisher: name: arXiv
Year: 2014
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We present a new formulation of Einstein's equations for an axisymmetric spacetime with vanishing twist in vacuum. We propose a fully constrained scheme and use spherical polar coordinates. A general problem for this choice is the occurrence of coordinate singularities on the axis of symmetry and at the origin. Spherical harmonics are manifestly regular on the axis and hence take care of that issue automatically. In addition a spectral approach has computational advantages when the equations are implemented. Therefore we spectrally decompose all the variables in the appropriate harmonics. A central point in the formulation is the gauge choice. One of our results is that the commonly used maximal-isothermal gauge turns out to be incompatible with tensor harmonic expansions, and we introduce a new gauge that is better suited. We also address the regularisation of the coordinate singularity at the origin.

description: Consider a line segment placed on a two-dimensional grid of rectangular tiles. This paper addresses the relationship between the length of the segment and the number of tiles it visits (i.e. has intersection with). The square grid is also considered explicitly, as some of the specific problems studied are more tractable in that particular case. The segment position and orientation can be modelled as either deterministic or random. In the deterministic setting, the maximum possible number of visited tiles is characterized for a given length, and conversely, the infimum segment length needed to visit a desired number of tiles is analyzed. In the random setting, the average number of visited tiles and the probability of visiting the maximum number of tiles on a square grid are studied as a function of segment length. These questions are related to Buffon's needle problem and its extension by Laplace.

title: Ethische Aspekte im digitalen Schulunterricht - mögliche Folgen und Erkenntnisse durch die schulische Situation in der COVID19-Pandemie
Creators: name: Mayer, Jasmin
Year: 2022

description: Durch die COVID-19-Pandemie entstand für die Schulen ein ethisches Dilemma. Einerseits haben Kinder und Jugendliche das Recht auf Bildung und andererseits haben sie das Recht auf körperliche Unversehrtheit. Da beide Rechte nicht gänzlich miteinander vereinbar waren, wurde der Kompromiss gewählt, das Schulleben in den digitalen Raum zu verlegen. Dadurch ergibt sich die Forschungsfrage, die dieser Arbeit zugrunde liegt: Welche ethischen Aspekte sind beim digitalen Unterricht zu beachten? Um diese Frage zu beantworten, gibt diese Masterarbeit einen Überblick über das erste Schuljahr in der Pandemie, erläutert die Grundlagen der Ethik, im Speziellen die der digitalen Ethik, und führt einige Herausforderungen der Digitalisierung an. Weiters stellt sie digitale Tools sowie Methoden für den digitalen Schulunterricht vor. Im Zuge der Arbeit werden ethische Fragestellungen formuliert und mit Lösungsansätzen kommentiert. Zuletzt werden einige Folgen für die Fachdidaktik Philosophie aufgezeigt und die Ausführungen zusammengefasst. Die Erarbeitung erfolgt durch die Methoden der Literaturrecherche und der Sprachanalyse. Es zeigt sich, dass die ethischen Aspekte, die beim digitalen Schulunterricht beachtet werden müssen, vielfältig sind. Lehrpersonen müssen beim Einsatz digitaler Medien auf den Zweck der Technologien sowie auf den Datenschutz achten. Weiters müssen alle Schüler*innen unabhängig ihres sozio-ökonomischen Status diese Tools nutzen können. Im digitalen Raum können sich die Akteur*innen menschlich verhalten, indem sie ihren Verstand benutzen und Verantwortung für ihr Handeln übernehmen. Weiters sind die Tugenden Besonnenheit, Großartigkeit, Großgesinntheit und Gerechtigkeit für den digitalen Raum erstrebenswert. Darüber hinaus sollen Kinder und Jugendliche bei der Aneignung sozialer Netzkompetenz sowie Werturteilskompetenz, tugendhafter Grundhaltung und Reflexionskompetenz unterstützt werden. Um dies zu gewährleisten, müssen digitale Endgeräte zum schulischen Alltag gehören und Lehrkräfte entsprechend in geschult werden. Abschließend lässt sich sagen, dass in weiterführenden Arbeiten die angeführten ethischen Aspekte vertiefend betrachtet werden sollten.

description: Researches in granular modeling produced a variety of mathematical models, such as intervals, (higher-order) fuzzy sets, rough sets, and shadowed sets, which are all suitable to characterize the so-called information granules. Modeling of the input data uncertainty is recognized as a crucial aspect in information granulation. Moreover, the uncertainty is a well-studied concept in many mathematical settings, such as those of probability theory, fuzzy set theory, and possibility theory. This fact suggests that an appropriate quantification of the uncertainty expressed by the information granule model could be used to define an invariant property, to be exploited in practical situations of information granulation. In this perspective, a procedure of information granulation is effective if the uncertainty conveyed by the synthesized information granule is in a monotonically increasing relation with the uncertainty of the input data. In this paper, we present a data granulation framework that elaborates over the principles of uncertainty introduced by Klir. Being the uncertainty a mesoscopic descriptor of systems and data, it is possible to apply such principles regardless of the input data type and the specific mathematical setting adopted for the information granules. The proposed framework is conceived (i) to offer a guideline for the synthesis of information granules and (ii) to build a groundwork to compare and quantitatively judge over different data granulation procedures. To provide a suitable case study, we introduce a new data granulation technique based on the minimum sum of distances, which is designed to generate type-2 fuzzy sets. We analyze the procedure by performing different experiments on two distinct data types: feature vectors and labeled graphs. Results show that the uncertainty of the input data is suitably conveyed by the generated type-2 fuzzy set models.

description: We consider the problem of finding a compromise between the opinions of a group of individuals on a number of mutually independent, binary topics. In this paper, we quantify the loss in representativeness that results from requiring the outcome to have majority support, in other words, the "price of majority support". Each individual is assumed to support an outcome if they agree with the outcome on at least as many topics as they disagree on. Our results can also be seen as quantifying Anscombes paradox which states that topic-wise majority outcome may not be supported by a majority. To measure the representativeness of an outcome, we consider two metrics. First, we look for an outcome that agrees with a majority on as many topics as possible. We prove that the maximum number such that there is guaranteed to exist an outcome that agrees with a majority on this number of topics and has majority support, equals $\ceil{(t+1)/2}$ where $t$ is the total number of topics. Second, we count the number of times a voter opinion on a topic matches the outcome on that topic. The goal is to find the outcome with majority support with the largest number of matches. We consider the ratio between this number and the number of matches of the overall best outcome which may not have majority support. We try to find the maximum ratio such that an outcome with majority support and this ratio of matches compared to the overall best is guaranteed to exist. For 3 topics, we show this ratio to be $5/6\approx 0.83$. In general, we prove an upper bound that comes arbitrarily close to $2\sqrt{6}-4\approx 0.90$ as $t$ tends to infinity. Furthermore, we numerically compute a better upper and a non-matching lower bound in the relevant range for $t$.

description: We show that exciton-type transport in certain materials can be dramatically modified by their inclusion in an optical cavity: the modification of the electromagnetic vacuum mode structure introduced by the cavity leads to transport via delocalized polariton modes rather than through tunneling processes in the material itself. This can help overcome exponential suppression of transmission properties as a function of the system size in the case of disorder and other imperfections. We exemplify massive improvement of transmission for excitonic wave-packets through a cavity, as well as enhancement of steady-state exciton currents under incoherent pumping. These results may have implications for experiments of exciton transport in disordered organic materials. We propose that the basic phenomena can be observed in quantum simulators made of Rydberg atoms, cold molecules in optical lattices, as well as in experiments with trapped ions.

description: The paper gives two approaches to write explicit presentations for the class of Dehn quandles using presentations of their underlying groups. The first approach gives finite presentations for Dehn quandles of a class of Garside groups and Gaussian groups. The second approach is for general Dehn quandles when the centralisers of generators of their underlying groups are known. Several examples including Dehn quandles of spherical Artin groups, surface groups and mapping class groups of orientable surfaces are given to illustrate the results.

Publisher: name: Zenodo
Year: 2024

description: This thesis is dedicated to the study of the modern features of using the spiritual heritage of the ancients in the development of the professional competence of teachers of the first grade. The legacy of the ancients, with its pedagogical, educational and spiritual aspects, can play an important role in improving the qualifications of classroom teachers. The article analyzes the innovations of the moderns in the field of education and training, the pedagogical principles and methods put forward by them, as well as how this heritage can be used in the current educational system. In particular, attention is paid to how modern methods of knowledge acquisition and education can help in the formation of professional competence of elementary school teachers. This study reveals the practical importance of the heritage of the ancients for the spiritual and moral development of elementary school teachers and the improvement of their pedagogical skills.

description: We applied the BEER algorithm to the CoRoT lightcurves from the first five LRc fields and identified $481$ non-eclipsing BEER candidates with periodic lightcurve modulations and amplitudes of $0.5-87$ mmag. Medium-resolution spectra of $281$ candidates were obtained in a seven-night AAOmega radial-velocity (RV) campaign, with a precision of $\sim1$ km/s. The RVs confirmed the binarity of $70$ of the BEER candidates, with periods of $0.3-10$ days.

description: A thorough understanding of neutrino-nucleus scattering physics is crucial for the successful execution of the entire US neutrino physics program. Neutrino-nucleus interaction constitutes one of the biggest systematic uncertainties in neutrino experiments - both at intermediate energies affecting long-baseline Deep Underground Neutrino Experiment (DUNE), as well as at low energies affecting coherent scattering neutrino program - and could well be the difference between achieving or missing discovery level precision. To this end, electron-nucleus scattering experiments provide vital information to test, assess and validate different nuclear models and event generators intended to be used in neutrino experiments. In this white paper, we highlight connections between electron- and neutrino-nucleus scattering physics at energies ranging from 10s of MeV to a few GeV, review the status of ongoing and planned electron scattering experiments, identify gaps, and layout a path forward that benefits the neutrino community. We also highlight the systemic challenges with respect to the divide between the nuclear and high-energy physics communities and funding that presents additional hurdle in mobilizing these connections to the benefit of neutrino programs.

Gibbs-Preserving Maps outperform Thermal Operations in the quantum regime

description: In this brief note, we compare two frameworks for characterizing possible operations in quantum thermodynamics. One framework considers Thermal Operations---unitaries which conserve energy. The other framework considers all maps which preserve the Gibbs state at a given temperature. Thermal Operations preserve the Gibbs state; hence a natural question which arises is whether the two frameworks are equivalent. Classically, this is true---Gibbs-Preserving Maps are no more powerful than Thermal Operations. Here, we show that this no longer holds in the quantum regime: a Gibbs-Preserving Map can generate coherent superpositions of energy levels while Thermal Operations cannot. This gap has an impact on clarifying a mathematical framework for quantum thermodynamics.

title: Einstellung gegenüber migrationsbedingter Mehrsprachigkeit in der Schule aus der Perspektive von Lehrkräften mit Migrationshintergrund in Wien
Creators: name: Bojic, Michelle
Year: 2022

description: Die hinter der Arbeit steckende Motivation galt der Frage, wie Lehrkräfte mit Migrationsgeschichte den Zusammenhang zwischen ihrer eigenen Sprachsozialisation und ihrer Einstellung gegenüber migrationsbedingter Mehrsprachigkeit in der Schule reflektieren. Nach der Klärung einiger Begriffe schafft der erste Teil der Arbeit einen Überblick über Migration in Österreich. Darauffolgend wird die theoretische Einordnung der Arbeit dargelegt. Das nächste Kapitel widmet sich der Mehrsprachigkeit und dem österreichischen Schulsystem, bevor ein Abriss der aktuellen Forschungslage zur Einstellung von Lehrpersonen zu Mehrsprachigkeit den Schluss des theoretischen Teils bildet. Um der Antwort auf die Forschungsfrage weiter nachzugehen, folgt der empirische Teil der Arbeit, der die Darstellung der Arbeit mithilfe von leitfadengestützten Interviews und der Analyse der Ergebnisse, für welche die qualitative Inhaltsanalyse nach Meuser und Nagel (1991) herangezogen wurde, bildet. Insgesamt wurden Interviews mit sieben Lehrkräften mit Migrationshintergrund aus unterschiedlichen NMS und AHS Schulen durchgeführt. Die qualitative Erhebung hat zum Ergebnis, dass Faktoren wie ein eigener Migrationshintergrund, die Erfahrungen in der eigenen Schulzeit, die Offenheit auf dem Arbeitsumfeld gegenüber Mehrsprachigkeit sowie Fortbildungen und Seminare zum Thema Mehrsprachigkeit die Einstellung von Lehrkräften gegenüber migrationsbedingter Mehrsprachigkeit beeinflussen können. Das Alter und die Anzahl der Berufsjahre stellen den Ergebnissen der vorliegenden Arbeit keine ausschlaggebenden Faktoren dar.
