title: Spanische Säle im habsburgischen Mitteleuropa als Quellen politischer Geschichte und Kulturgeschichte in der Frühen Neuzeit
Creators: name: Fleckl, Anton Karl
Year: 2023

description: In Mitteleuropa, genauer gesagt im Einflussgebiet der Habsburger, entstanden zwischen der Mitte des 16. Jahrhunderts und der Mitte des 18. Jahrhunderts Räume, die als Spanische Säle bezeichnet werden. Es handelt sich dabei um Säle auf Schloss Ambras bei Innsbruck (errichtet ab dem Jahr 1569), in der Prager Burg (errichtet ab dem Jahr 1602), auf Schloss Náchod in Nordböhmen (errichtet ab dem Jahr 1650) und in der Wiener Hofburg (errichtet ab dem Jahr 1700). Diese Räume verfügen zwar über verschiedene Gemeinsamkeiten, wie zum Beispiel Grundriss und Lichtführung, sind jedoch von ihrer Ausstattung her ausgesprochen unterschiedlich. Es ist daher erstaunlich, dass dennoch jeder von ihnen als Spanischer Saal bezeichnet wird. Die älteste gesicherte Bezeichnung als Spanischer Saal finden wir in der Prager Burg. Die Quelle mit der Bezeichnung stammt aus dem Jahr 1621. Für die anderen Spanischen Säle ist die Namenszuschreibung zu unterschiedlichen, teilweise späteren Zeitpunkten geschuldet. Die Frage der Namensgebung, Funktion und Gemeinsamkeiten der Spanischen Säle, ihre Entstehungsgeschichte sowie die Geschichte ihrer Auftraggeber ist das Thema dieser Forschungsarbeit. Für die vorgestellten Säle sind Erzherzog Ferdinand II. von Tirol (Ambras), Kaiser Rudolf II. (Prag), Octavio Piccolomini (Náchod) und Kaiser Leopold I. (Wien) als Bauherren verantwortlich. Schnell kristallisierte sich heraus, dass die Biographie des Octavio Piccolomini ein bisher unbearbeitetes Desiderat darstellt. Daher ist es angebracht, seiner Biographie etwas mehr Platz in dieser Arbeit einzuräumen. Der älteste der Spanischen Säle - jener auf Schloss Ambras - strahlte auch auf fürstliche Residenzen nördlich (Günzburg) und südlich (Sabbioneta) der Alpen aus. Diese beiden Anlagen sowie deren Auftraggeber, Markgraf Karl von Burgau (Günzburg) und Vespasiano Gonzaga (Sabbioneta), sind ebenfalls Gegenstand dieser Untersuchung. Die Beschäftigung mit der Kunstpatronanz Kaiser Leopold I. kann nicht ohne einer Auseinandersetzung mit Schloss Schönbrunn stattfinden. Überlegungen zur Namensfindung von Schloss Schönbrunn vor dem Hintergrund der in der Arbeit ausführlich beschriebenen politischen Verhältnisse stellen eine spannende neue These zur Diskussion.

description: Digitale Geodaten stellen eine wichtige Querschnittsressource für die öffentliche Leistungserbringung dar. Durch die INSPIRE-Richtlinie wurden hierzu europaweite Standards etabliert. In der Praxis zeigt sich jedoch, dass nicht nur anwendungsbezogene Probleme im Hinblick auf Datenqualität und Schnittstellen existieren, sondern dass auch die Datenerhebung und deren Pflege Kommunen, Länder und Bund auf eine harte Probe stellen. In diese komplexe Gemengelage ist das Onlinezugangsgesetz (OZG) einzubetten, das Bund, Länder und Kommunen dazu verpflichtet, 575 identifizierte Verwaltungsdienstleistungen auch digital anzubieten. Bei dessen Implementierung sind Geodaten ein entscheidender Baustein. In diesem Zusammenhang wurden im Rahmen des Forschungsprojektes Smart Development Infrastructure (SARDINE) Experteninterviews im Freistaat Sachsen mit Akteuren auf Ebene der Kommunen und des Landes durchgeführt. Diese zeigen, dass die Zielstellungen der Umsetzung des OZG und der Einbettung von Geodaten in das Verwaltungshandeln bekannt sind, jedoch Hemmnisse existieren, die dessen Implementierung erschweren. Der vorliegende Beitrag benennt und systematisiert diese Problemstellungen und zeigt mögliche Handlungsoptionen auf.

description: Our purpose is to evaluate the rate of the maximum energy and the acceleration rate that cosmic rays acquire in the non-relativistic diffusive shock acceleration as it could apply during their lifetime in various astrophysical sites, where highly oblique shocks exist. We examine numerically (using Monte Carlo simulations) the effect of the diffusion coefficients on the energy gain and the acceleration rate, by testing the role between the obliquity of the magnetic field to the shock normal, and the significance of both perpendicular cross-field diffusion and parallel diffusion coefficients to the acceleration rate. We find (and justify previous analytical work - Jokipii 1987) that in highly oblique shocks the smaller the perpendicular diffusion gets compared to the parallel diffusion coefficient values, the greater the energy gain of the cosmic rays to be obtained. An explanation of the cosmic ray spectrum in high energies, between $10^{15}$eV and about $10^{18}$eV is claimed, as we estimate the upper limit of energy that cosmic rays could gain in plausible astrophysical regimes; interpreted by the scenario of cosmic rays which are injected by three different kind of sources, (a) supernovae which explode into the interstellar medium, (b) Red Supergiants, and (c) Wolf-Rayet stars, where the two latter explode into their pre-supernovae winds.

description: We analysed 13 years of the Neil Gehrels Swift Observatory survey data collected on the High Mass X-ray Binary IGR J18214-1318. Performing the timing analysis we detected a periodic signal of 5.42 d. From the companion star characteristics we derived an average orbital separation of $\sim 41 \rm R_{\odot}\simeq 2 R_{\star}$. The spectral type of the companion star (O9) and the tight orbital separation suggest that IGR~J18214-1318 is a wind accreting source with eccentricity lower than 0.17. The intensity profile folded at the orbital period shows a deep minimum compatible with an eclipse of the source by the companion star. In addition, we report on the broad-band 0.6--100 keV spectrum using data from XMM-Newton, NuSTAR, and Swift, applying self-consistent physical models. We find that the spectrum is well fitted either by a pure thermal Comptonization component, or, assuming that the source is a neutron star accreting above the critical regime, by a combined thermal and bulk-motion Comptonization model. In both cases, the presence of a local neutral absorption (possibly related to the thick wind of the companion star) is required.

description: A critical analysis of recent advances in synthesis and electrical characterization of nanofibers and nanotubes made of different conjugated polymers is presented. The applicability of various theoretical models is considered in order to explain results on transport in conducting polymer nanofibers and nanotubes. The relationship between these results and the one-dimensional (1D) nature of the conjugated polymers is discussed in light of theories for tunneling in 1D conductors (e.g. Luttinger liquid, Wigner crystal). The prospects for nanoelectronic applications of polymer fibers and tubes as wires, nanoscale field-effect transistors (nanoFETs), and in other applications are analyzed.

description: Wake word (WW) spotting is challenging in far-field not only because of the interference in signal transmission but also the complexity in acoustic environments. Traditional WW model training requires large amount of in-domain WW-specific data with substantial human annotations therefore it is hard to build WW models without such data. In this paper we present data-efficient solutions to address the challenges in WW modeling, such as domain-mismatch, noisy conditions, limited annotation, etc. Our proposed system is composed of a multi-condition training pipeline with a stratified data augmentation, which improves the model robustness to a variety of predefined acoustic conditions, together with a semi-supervised learning pipeline to accurately extract the WW and confusable examples from untranscribed speech corpus. Starting from only 10 hours of domain-mismatched WW audio, we are able to enlarge and enrich the training dataset by 20-100 times to capture the acoustic complexity. Our experiments on real user data show that the proposed solutions can achieve comparable performance of a production-grade model by saving 97\% of the amount of WW-specific data collection and 86\% of the bandwidth for annotation.

description: Advances in metering infrastructure, data collection and storing have led to data-driven research approaches such as machine learning to become more revalent in environmental and sustainability research. However, probabilistic approaches which handle uncertainty in the available data and models are still underrepresented. This underrepresentation is prevalent in environmental research, in addition there are different uncertainties influence the models we design and their output. For example, the data sets we have at hand are not always equally well distributed in space and time; some areas might have lots of data points (high resolution in space) while others might have more frequent data (high resolution in time). When working with a mixed data set, probabilistic measures can help clarify where the models are certain about the results and where they are uncertain. Additionally, many research questions we want to answer, such as the optimal location for a wind turbine, rely on weather and climate data input. As weather and climate are a chaotic system and thus only predictable to a certain extent, accounting for this uncertainty is crucial for reliable forecasts and any decision making based on them. In this talk, we will address some of the open issues with uncertainty in space and time in the input data and output of probabilistic machine learning models at the example of forecasting in sustainable energy systems.

description: Total hip replacement is the most effective treatment for late stage osteoarthritis. However, adverse local tissue reactions (ALTRs) associated with fretting corrosion have been observed in patients with modular total hip implants. The purpose of this study is to increase the fretting corrosion resistance of the CoCrMo alloy and the associated metal ion release by applying hard coatings to the surface. Cathodic arc evaporation technique (arc-PVD) was used to deposit TiSiN and ZrN hard coatings on to CoCrMo substrates. The morphology, chemical composition, crystal structures and residual stress of the coatings were characterized by scanning electron microscopy, energy dispersive x-ray spectroscopy, and X-ray diffractometry. Hardness, elastic modulus, and adhesion of the coatings were measured by nano-indentation, nano-scratch test, and the Rockwell C test. Fretting corrosion resistance tests of coated and uncoated CoCrMo discs against Ti6Al4V spheres were conducted on a four-station fretting testing machine in simulated body fluid at 1Hz for 1 million cycles. Post-fretting samples were analyzed for morphological changes, volume loss and metal ion release. Our analyses showed better surface finish and lower residual stress for ZrN coating, but higher hardness and better scratch resistance for TiSiN coating. Fretting results demonstrated substantial improvement in fretting corrosion resistance of CoCrMo with both coatings. ZrN and TiSiN decreased fretting volume loss by more than 10 times and 1000 times, respectively. Both coatings showed close to 90% decrease of Co ion release during fretting corrosion tests. Our results suggest that hard coating deposition on CoCrMo alloy can significantly improve its fretting corrosion resistance and could thus potentially alleviate ALTRs in metal hip implants.

Condensation of exciton–polaritons in complex potentials

Subjects: exciton-polaritons, Bose-Einstein condensate, exciton-polariton condensates, non-Hermitian physics, strong light-matter coupling

description: Bose–Einstein condensates (BEC) of exciton–polaritons represent a successful platform for studies of macroscopic quantum physics at elevated temperatures in a solid-state device. Despite the number of breakthroughs in both experiment and theory, there are still some gaps in our understanding of this part-light part-matter system. The difficulties in our interpretation of the system’s behavior arise from the inherent non-equilibrium nature of exciton–polaritons and their coupling with a reservoir of thermal excitons. This optically induced reservoir creates a repulsive potential and serves as a gain medium or source for exciton–polaritons, thus creating a complex-valued potential. In this Thesis, I summarize my PhD work on trapping, controlling, and manipulating exciton–polariton condensates using this complex potential. Chapter 1 of this Thesis introduces the topic of exciton-polariton condensation, the experimental and modeling techniques used in my work, as well as methods for potential landscape engineering for exciton–polaritons. Chapter 2 presents experiments on trapping the condensate in a one-dimensional array of photonic traps, and controlling the population of different energy states in the band-gap structure by applying a spatially structured pump. Chapter 3 demonstrates how the implementation of the finely controlled, fully optically-induced potentials allows us to finely tune the energy and linewidth of the condensate and elucidate its non-Hermitian nature through observation of non-Hermitian spectral degeneracies. Chapter 4 presents a detailed study of the condensation process in the presence of thermal reservoir, which is inherent in optically-induced trapping. Using an ultra-high-Q microcavity, we image single realizations of condensation with unprecedented detail, and observe filamentation of the condensate, which is a direct consequence of reservoir depletion. Chapter 5 presents further work performed in this “single-shot” regime, where we drive the condensate into the high-density regime, and, assisted by the reservoir depletion, observe a homogeneous profile characteristic of the Thomas–Fermi limit. Furthermore, the spectrum of the high-density condensate shows signatures of crossover from BEC to the Bardeen–Cooper–Schrieffer state, which represents a starting point for future studies beyond the scope of this Thesis.

title: Causally consistent abstractions of time-series data
Creators: name: Kumar, Akshey
Year: 2023

description: Das Verständnis komplexer dynamischer Systeme, insbesondere im Bereich der Neurowissenschaften, stellt aufgrund der hohen Dimensionalität und Komplexität der verfügbaren Daten eine große Herausforderung dar. In dieser Dissertation wird zwar die Bedeutung des Nachweises kausaler Beziehungen anerkannt, doch reicht ein rein kausales Verständnis möglicherweise nicht aus, da es zu komplex ist, um interpretiert werden zu können. Daher sehen wir einen Bedarf an kausal konsistenten Abstraktionen. Um dies zu erreichen, stellen wir einen mathematischen Rahmen vor, der die Ableitung von kausal konsistenten Modellen auf hoher Ebene direkt aus Beobachtungsdaten ermöglicht. Anschließend stellen wir BunDLe-Net vor - einen Algorithmus zum Lernen von High-Level-Modellen direkt aus neuronalen und Verhaltensdaten. Die Wirksamkeit unserer Architektur wird anhand verschiedener Modalitäten neurowissenschaftlicher Daten demonstriert, die durchweg interpretierbare Erkenntnisse liefern, die nicht nur mit dem vorhandenen Wissen übereinstimmen, sondern auch neue Erkenntnisse über die Daten offenbaren. Darüber hinaus wird in dieser Arbeit eine Toolbox für die Implementierung von BunDLe-Net vorgestellt. Schließlich diskutieren wir zukünftige Forschungsmöglichkeiten, die unsere Arbeit in einer Vielzahl von wissenschaftlichen Bereichen wie Kausalität, Datenwissenschaft und Neurowissenschaften eröffnet.
description: Understanding complex dynamical systems, particularly in the realm of neuroscience, poses significant challenges due to the high dimensionality and intricacy of available data. While acknowledging the significance of establishing causal relationships, this dissertation contends that a mere causal understanding may not suffice since it may be too complex to be interpretable. Hence, we identify the need for causally consistent abstractions. To address this, we present a mathematical framework outlining key assumptions that facilitate the derivation of causally-consistent high-level models directly from observational data. We then introduce BunDLe-Net – an architecture to learn high-level models directly from neuronal and behavioural time-series data. The efficacy of our architecture is demonstrated across various modalities of neuroscience data, which consistently produces interpretable insights that not only align with existing knowledge but also reveal novel insights about the data. Additionally, this thesis introduces a toolbox for the implementation of BunDLe-Net. Finally, we discuss future avenues for research that our work opens up in a variety of scientific domains, such as causality, data science and neuroscience.

description: High angular resolution images of the complex gravitational lens system RXS J1131-1231 (a quadruply imaged AGN with a bright Einstein ring) obtained with the Advanced Camera for Surveys and NICMOS instruments onboard the Hubble Space Telescope are analysed to determine the lens model and to reconstruct the host galaxy. Results: 1- Precise astrometry and photometry of the four QSO lensed images (A-D) and of the lensing galaxy (G) are obtained. They are found in agreement with an independent study presented in a companion paper. The position and colours of the X object seen in projection close to the lens are found to be only compatible with a satellite galaxy associated with the lens. 2- The Singular Isothermal Ellipsoid plus external shear provides a good fit of the astrometry of images A-D. The positions of extended substructures are also well reproduced. However an octupole (m=4) must be added to the lens potential in order to reproduce the observed lens position, as well as the IB/IC point-like image flux ratio. The ellipticity and orientation of the mass quadrupole are found similar to those of the light distribution, fitted by a Sersic profile. The lens (z=0.295) is found to be a massive elliptical in a rich environment and showing possible evolution with respect to z=0. 3- The host galaxy (z=0.658) is found to be a substantially magnified (M ~ 9) luminous Seyfert 1 spiral galaxy. The angular resolution is sufficient to see regions where stars are intensively forming. Interaction with a closeby companion is also observed. 4- Finally, in the case of RXS J1131-1231, extended lensed structures do not help much in constraining the lens model.

A method for assessment of the effectiveness of feeding stimulants for salmonid fish: trials with krill (Euphausia pacifica) hydrolysates
Creators: name: Oikawa, Christopher Keiya
Publisher: name: University of British Columbia
Year: 2009

description: A procedure was devised to assess the efficacy of processed krill (Euphausia pacified) products as potential feeding stimulants for rainbow trout (Oncorhynchus mykiss) in a diet containing 60% plant material. Three experiments were conducted. Test substances were added in substitution for, on a dry weight basis, 2% of the fishmeal in the control diet, and were either mixed into the diet prior to pelleting, or coated on the pellet surface. Fish were fed to satiation once daily. Feed intake and wastage were measured in one-minute intervals by feeding from separate containers in each minute of feeding and counting the number of uneaten pellets at the tank bottom after each minute. Feed was dispensed using a plastic spoon to prevent scent/flavour contamination of the diets. All the products, with the exception of two commercial preparations, resulted in 1) an increase in the rate and amount of feed consumed, 2) increased growth and 3) decreased feed wastage relative to the control diet. Coating of pellets with the products enhanced the effects, and resulted in the highest feed intake in all three experiments. In all experiments the rate of feed intake was highest in the first minute of feeding and declined rapidly until satiation was reached. Differences in feed consumption were evident in the first minute of feeding, and in the first 5 days of the feeding trial. Wastage was negligible in the first two minutes of feeding, but increased as satiation was approached. Less palatable diets were wasted earlier in the feeding process. The benefits yielded from the use of feeding stimulants appear to be long term. Measurement of feed consumption rate and wastage increased the sensitivity of the technique and yielded consistent and repeatable results.

description: We describe the implementation of the shearingbox approach into the Godunov-type central-upwind/constraint-transport magnetohydrodynamics code NIRVANA. This will allow for applications which require sheared-periodic boundary conditions as typically used in local Cartesian simulations of differentially rotating systems. We present the algorithm in detail and discuss necessary modifications in the numerical fluxes in order to preserve conserved quantities and to fulfill other analytical constraints as good as seem feasible within the numerical scheme. We check the source terms which come with the shearingbox formulation by investigating the conservation of the epicyclic mode energy. We also perform more realistic simulations of the magneto-rotational instability with initial zero-net-flux vertical magnetic field and compare the obtained stresses and energetics with previous non-conservative results exploring the same parameter regime.

description: The System Usability Scale (SUS) is a short, survey-based approach used to determine the usability of a system from an end user perspective once a prototype is available for assessment. Individual scores are gathered using a 10-question survey with the survey results reported in terms of central tendency (sample mean) as an estimate of the system's usability (the SUS study score), and confidence intervals on the sample mean are used to communicate uncertainty levels associated with this point estimate. When the number of individuals surveyed is large, the SUS study scores and accompanying confidence intervals relying upon the central limit theorem for support are appropriate. However, when only a small number of users are surveyed, reliance on the central limit theorem falls short, resulting in confidence intervals that suffer from parameter bound violations and interval widths that confound mappings to adjective and other constructed scales. These shortcomings are especially pronounced when the underlying SUS score data is skewed, as it is in many instances. This paper introduces an empirically-based remedy for such small-sample circumstances, proposing a set of decision rules that leverage either an extended bias-corrected accelerated (BCa) bootstrap confidence interval or an empirical Bayesian credibility interval about the sample mean to restore and bolster subsequent confidence interval accuracy. Data from historical SUS assessments are used to highlight shortfalls in current practices and to demonstrate the improvements these alternate approaches offer while remaining statistically defensible. A freely available, online application is introduced and discussed that automates SUS analysis under these decision rules, thereby assisting usability practitioners in adopting the advocated approaches.
title: On Putnam's concept of practical rationality
Creators: name: Mayer, Lynette Mildred
Year: 2023

description: Wissenschaftliche und ethische Aussagen werden allgemein als diametral zueinander gesehen. In The Collapse of the fact/value Dichotomy vertritt Putnam die These, dass diese Dichotomie nicht aufrecht zu erhalten ist. Deshalb ist es notwendig, eine neue Konzeption praktischer Rationalität zu entwerfen. Ziel dieser Arbeit ist es, Putnams Ausführungen dazu zu untersuchen. Putnams Ansatz ist im Pragmatismus verwurzelt, den er um seine Verflechtungsthese erweitert. Nach dieser These ist die Einbeziehung von Werturteilen in die praktische Rationalität möglich. Für Akteure wird es rational, über ihre eigenen Werte zu entscheiden. Diese Werte sind nicht endgültig oder normativ, sondern müssen rationalen Diskursen standhalten. Der Diskurs wird dabei als ein komplexer und kontextabhängiger Prozess verstanden. Werturteile und Begründung (Validität) sind nun miteinander verknüpft. Putnam behauptet, dass Objektivität in der Ethik erreicht werden kann. Der Zusammenbruch der Fakten-/Werturteil-Dichotomie erfordert ein Umdenken in der Metaphysik und normativen Ethik und bringt eine Form praktischer Rationalität hervor, die auf Handlungsfähigkeit, Praxis und Kollektivität basiert.
description: The common view today is that scientific and ethical statements are seen as diametral to each other. In The Collapse of the fact/value Dichotomy Putnam states that the view of these strict dichotomies is unattainable. With the collapse of the dichotomy of fact and value, there is need for a new conception of practical rationality. The aim of the thesis is to examine Putnam’s conception of practical rationality in view of this collapse. His idea is rooted in pragmatism and is contingent on the premise of the entanglement thesis. Through the inclusion of values, it is rational for an agent to choose their own values. This standpoint is not final, or normative. Reasons need to be objectively justified through rational testing. Rationality is understood as a complex and context-dependent process where reason is related to moral considerations. Putnam claims that objectivity can be achieved in ethics. The collapse of the fact/value dichotomy implies to rethink metaphysics and normative ethics and brings forward a form of practical rationality that is set in agency, practice, and collectivity.

description: In the context of the minimal supersymmetric seesaw model, the CP-violating neutrino Yukawa couplings might induce an electron EDM. The same interactions may also be responsible for the generation of the observed baryon asymmetry of the Universe via leptogenesis. We identify in a model-independent way those patterns within the seesaw models which predict an electron EDM at a level probed by planned laboratory experiments and show that negative searches on τ-> e γdecay may provide the strongest upper bound on the electron EDM. We also conclude that a possible future detection of the electron EDM is incompatible with thermal leptogenesis, even when flavour effects are accounted for.

description: Dieser Leitfaden untersucht den Einsatz generativer Künstlicher Intelligenz (KI) in schulischen Facharbeiten und adressiert damit die wachsenden Herausforderungen und Potenziale, die durch die Integration solcher Technologien in wissenschaftspropädeutische Lernprozesse entstehen. Ziel ist es, Schüler:innen methodisch fundierte Ansätze an die Hand zu geben, um KI-Tools effektiv für Themenfindung, Recherche, Textproduktion, Korrektur und Reflexion einzusetzen. Dabei wird ein praxisnaher Ansatz verfolgt, der die Förderung von Zukunftskompetenzen (Kommunikation, Kollaboration, Kreativität, kritisches Denken) unterstützt und gleichzeitig die Eigenleistung und den reflektierten Umgang mit KI gewährleistet.

Die Methodik umfasst die Analyse des KI-gestützten Schreibprozesses, die Sensibilisierung für ethische und datenschutzrechtliche Aspekte sowie die Entwicklung innovativer Prüfungsformate. Der Leitfaden schlägt eine prozessbegleitende Neustrukturierung der Facharbeit vor, die Konsultationen und Verteidigungen als Bewertungselemente integriert, um die wissenschaftliche Auseinandersetzung zu vertiefen und die Eigenleistung besser nachzuvollziehen. Der Text ist unter einer Creative-Commons-Lizenz (CC BY) verfügbar und bietet eine Grundlage für die Weiterentwicklung schulischer Lehr- und Prüfungsformate im Zeitalter von KI.
title: Kultursensible Therapie von mehrsprachig sozialisierten Kindern mit Sprachentwicklungsstörung
Creators: name: Gschweitl, Elisa
Year: 2023

description: Mehrsprachig sozialisierte Kinder sind genauso oft wie einsprachig sozialisierte Kinder von Sprachentwicklungsstörungen (SES) betroffen. Jedoch gibt es verhältnismäßig wenige Daten zur Diagnostik und Therapie von dieser Klientel, was oftmals eine logopädische Fehlversorgung von mehrsprachig sozialisierten Kindern zur Folge hat. Im Rahmen der vorliegenden Arbeit sollte gezeigt werden, wie auf den sprachlich und kulturell diversen Hintergrund der Kinder Rücksicht genommen werden kann, um dadurch den logopädischen Prozess positiv zu beeinflussen. Dafür wurden sieben Expert:inneninterviews geführt und anhand einer qualitativen Inhaltsanalyse ausgewertet. Die Ergebnisse zeigen, dass für die logopädische Arbeit mit linguistisch und kulturell diversen Kindern ein breites Spektrum an Kompetenzen von therapeutischer Seite erforderlich ist. Die Basis für diese Kompetenzen sollte schon im Rahmen der Ausbildung durch eine Verankerung des Themas „Mehrsprachigkeit“ in den Curricula der Hochschulen gelegt werden. Zur Verringerung von Fehleinschätzungen bezüglich der Sprachentwicklung von mehrsprachig sozialisierten Kindern sollte die Umfeldarbeit im logopädischen Prozess nicht zu kurz kommen, wobei ein systemischer Ansatz verfolgt werden sollte. Weitere Forschungsprojekte sollten sich in Zukunft auf Diagnostik und Therapie von mehrsprachig sozialisierten Kindern mit SES fokussieren und auch die Entwicklung von kultursensiblem Diagnostik- und Therapiematerial ist wünschenswert.

Experimentally Testing a Generalized Coarsening Model for Individual Bubbles in Quasi-Two-Dimensional Wet Foams

description: We present high-precision data for the time evolution of bubble area $A(t)$ and circularity shape parameter $C(t)$ for quasi-2d foams consisting of bubbles squashed between parallel plates. In order to fully compare with predictions by Roth et al. [Phys. Rev. E 87 2013] and Schimming et al. [Phys. Rev. E 96 2017], foam wetness is systematically varied by controlling the height of the sample above a liquid reservoir which in turn controls the radius $r$ of the inflation of the Plateau borders. For very dry foams, where the borders are very small, classic von Neumann behavior is observed where a bubble's growth rate depends only on its number $n$ of sides. For wet foams, the inflated borders impede gas exchange and cause deviations from von Neumann's law that are found to be in accord with the generalized coarsening equation. In particular, the overall growth rate varies linearly with the film height, which decrease as surface Plateau borders inflate. And, more interestingly, the deviation from $dA/dt\propto (n-6)$ von Neumann behavior grows in proportion to $nCr/\sqrt{A}$. This is highlighted definitively by data for six-sided bubbles, which are forbidden to grow or shrink except for the existence of this term. And it is tested quantitatively by variation of all four relevant quantities: $n$, $C$, $r$, and $A$

description: Quantization of the noncommutative geometric spectral action has so far been performed on the final component form of the action where all traces over the Dirac matrices and symmetry algebra are carried out. In this work, in order to preserve the noncommutative geometric structure of the formalism, we derive the quantization rules for propagators and vertices in matrix form. We show that the results in the case of a product of a four-dimensional Euclidean manifold by a finite space, could be cast in the form of that of a Yang-Mills theory. We illustrate the procedure for the toy electroweak model.

'I paint for everyone' - the making of Utopia art

description: At the core of this research is the history and development over the past four decades of the Utopia art movement in Central Australia. Initiated as an adult education programme teaching batik-making in the late 1970s it has since become nationally and internationally renowned. However, much of its history is not recorded, nor are the artworks and its records kept in a database entertained by a community art centre or similar institution. Despite this apparent lack of recording and documentation much has been written about the artworks as well as about some artists from Utopia. Critics engaging with art from Utopia praise it in terms of 'abstract', 'abstract expressionist', 'impressionistic' and even 'similar to European masters of the 20th century'. I question whether these similarities are a result of the close interaction with the art world and possibly even the reaction to the demands made on 'artists' to satisfy a certain prevailing taste in the arts? How do artists negotiate these market demands and their relationships with the art world? I argue that through close observation of artistic practices and negotiation processes between artists and art dealers, artists' agency can be uncovered. Throughout the history of the art movement artists have had to become their own agents in dealing with art dealers, wholesalers, curators and collectors. Being one's own agent in the art world might have a far greater influence on the art than has been discussed to date. Influences of art dealers, the art world, families, artists in the community, everyday life and the constraints associated with living in a remote community all affect the creation of artworks. By looking at the artworks through the framework of influence, similarities and differences in art from Utopia become apparent. The different currents and sub-currents found in Utopia art will be defined and described by means of a close formal analysis of the artworks. Combining this formal analysis with methods of new art history, such as qualitative interviews and observation of art practice, will reveal the influences and effects on artworks. Finally this examination of artworks and relationships in the art world will facilitate a better understanding of the emerging of local art movements, their development and their multi-layered histories. Furthermore it will give a point of comparison for further studies and research into Indigenous art histories throughout Australia. -- provided by Candidate.
