title: Methodische Berechnungen in der Humangenetik und die fachdidaktische Umsetzung anhand von ausgewählten Beispielen
Creators: name: Hoffmann, Sandra
Year: 2021

description: Hintergrund Diese Diplomarbeit beschreibt die Grundzüge der Vererbung, einige methodische Berechnungen in der Humangenetik, und, ausgehend von eigenen Erfahrungen als Mathematik- und Biologielehrerin, zeigt sie auch die fachdidaktische Umsetzung dieses Themas in der Schule, und zwar in der Oberstufe, mit Bezug auf den Lehrplan Allgemeinbildender Höherer Schulen. Ziel Diese Arbeit soll zeigen, wie ein fächerübergreifender Unterricht aussehen kann und wie komplexe Themen den SchülerInnen vermittelt werden können, sodass diese nicht nur die jeweiligen Grundlagen kennen lernen, sondern auch in der Lage sind, eigenständig Zusammenhänge zu finden. Methode Um zu diesen Ergebnissen zu kommen, wurde eine Literaturrecherche durchgeführt. Dabei wurden Werke aus der Universitätsbibliothek Wien, Internetrecherchen, sowie ausgewählte Schulbücher als Literaturquellen verwendet. Ergebnisse Im Rahmen dieser Arbeit entstand nicht nur ein Überblick über wichtige Grundlagen der Humangenetik zusammen mit ausgewählten Berechnungen, sondern auch eine brauchbare Unterrichtsplanung, die als Leitfaden für den eigenen Unterricht dienen soll. Durch den Schulbuchvergleich und den Bezug zum Lehrplan konnte ein passender Zeitpunkt der Durchführung gefunden werden, und auch die inhaltliche Aufbereitung ist so gewählt, dass die SchülerInnen ihre fachlich-methodischen Kompetenzen erweitern können.
description: Background This diploma paper focuses on the foundations of inheritance with the help of methodology-based calculations in human genetics. Drawing on my own experiences as a teacher of mathematics and biology it also shows the didactical implementation of this topic in upper secondary classes, as required by the curriculum. Aim Moreover, it will be shown what an interdisciplinary lesson combining both mathematical and biological findings could look like and how complex issues can be conveyed to the students. Methods The findings of this study are literature-based. The main sources were works from the UB Wien, the internet and widely-used school manuals. Results The paper not only provides a survey of the basics of human genetics but also detailed lesson planning, which may serve as guideline for actual classroom work. Due to the comparison of teaching material and the requirements of the curriculum, a suitable schedule for implementing relevant content was established. Thereby students are given the opportunity of expanding gaining and improving relevant skills and competences.

description: We analyse the velocity dispersion for eight of the Milky Way dwarf spheroidal satellites in the context of finite temperature scalar field dark mater. In this model the finite temperature allows the scalar field to be in configurations that possess excited states, a feature that has proved to be necessary in order to explain the asymptotic rotational velocities found in low surface brightness (LSB) galaxies. In this work we show that excited states are not only important in large galaxies but also have visible effects in dwarf spheroidals. Additionally, we stress that contrary to previous works where the scalar field dark matter haloes are consider to be purely Bose-Einstein condensates, the inclusion of excited states in these halo configurations provides a consistent framework capable of describing LSBs and dwarf galaxies of different sizes without arriving to contradictions within the scalar field dark matter model. Using this new framework we find that the addition of excited states accounts very well for the raise in the velocity dispersion in Milky Way dwarf spheroidal galaxies improving the fit compared to the one obtained assuming all the DM to be in the form of a Bose Einstein Condensate.

description: Nowadays, utilizing Advanced Driver-Assistance Systems (ADAS) has absorbed a huge interest as a potential solution for reducing road traffic issues. Despite recent technological advances in such systems, there are still many inquiries that need to be overcome. For instance, ADAS requires accurate and real-time detection of pedestrians in various driving scenarios. To solve the mentioned problem, this paper aims to fine-tune the YOLOv5s framework for handling pedestrian detection challenges on the real-world instances of Caltech pedestrian dataset. We also introduce a developed toolbox for preparing training and test data and annotations of Caltech pedestrian dataset into the format recognizable by YOLOv5. Experimental results of utilizing our approach show that the mean Average Precision (mAP) of our fine-tuned model for pedestrian detection task is more than 91 percent when performing at the highest rate of 70 FPS. Moreover, the experiments on the Caltech pedestrian dataset samples have verified that our proposed approach is an effective and accurate method for pedestrian detection and can outperform other existing methodologies.

description: Let $Q_d$ denote the hypercube of dimension $d$. Given $d\geq m$, a spanning subgraph $G$ of $Q_d$ is said to be $(Q_d,Q_m)$-saturated if it does not contain $Q_m$ as a subgraph but adding any edge of $E(Q_d)\setminus E(G)$ creates a copy of $Q_m$ in $G$. Answering a question of Johnson and Pinto, we show that for every fixed $m\geq2$ the minimum number of edges in a $(Q_d,Q_m)$-saturated graph is $Θ(2^d)$. We also study weak saturation, which is a form of bootstrap percolation. A spanning subgraph of $Q_d$ is said to be weakly $(Q_d,Q_m)$-saturated if the edges of $E(Q_d)\setminus E(G)$ can be added to $G$ one at a time so that each added edge creates a new copy of $Q_m$. Answering another question of Johnson and Pinto, we determine the minimum number of edges in a weakly $(Q_d,Q_m)$-saturated graph for all $d\geq m\geq1$. More generally, we determine the minimum number of edges in a subgraph of the $d$-dimensional grid $P_k^d$ which is weakly saturated with respect to `axis aligned' copies of a smaller grid $P_r^m$. We also study weak saturation of cycles in the grid.

description: In an effective theory approach, the full minimal set of leading contributions to anomalous charged-current top couplings comprises various new trilinear tbW as well as quartic tbff' interaction vertices, some of which are related to one another by equations of motion. While much effort in earlier work has gone into the extraction of the trilinear couplings from single top measurements, we argue in this article that these structures can be assessed independently by other observables, while single top production forms a unique window to the four-fermion sector. An effective theory approach is employed to infer and classify the minimal set of such couplings from dimension six operators in the minimal flavor violation scheme. In the phenomenological analysis, we present a Monte Carlo study at detector level to quantify the expected performance of the next LHC run to bound as well as distinguish the various contact couplings. Special attention is directed toward differential final state distributions including detector effects as a means to optimize the signal sensitivity as well as the discriminative power with respect to the possible coupling structures.

description: Atmospheric neutrinos are an important background to astrophysical neutrino searches, and are also of considerable interest in their own right. This paper points out that the contribution to conventional atmospheric $ν_e$ of the rare semileptonic decay of $K_S$ becomes significant at high energy. Although the $K_S\rightarrow πeν$ branching ratio is very small, the short $K_S$ lifetime leads to a high critical energy, so that, for vertical showers, the inclusion of $K_S$ semileptonic decay increases the conventional $ν_e$ flux by $\approx 30%$ at energies above 100 TeV. In this paper, we present calculations of the flux of $ν_e$ from $K_S$. At energies above their critical energies, the $ν_e$ fluxes from kaon decay may be simply related to the kaon semileptonic widths; this leads to a near-equality between the flux of $ν_e$ from $K^+$, $K_L$ and $K_S$.

title: Hormonelle Verhütung für Männer
Creators: name: Moser, Susanne
Year: 2021

description: Mit dieser Studie wurde untersucht ob die Variablen Bindungsqualität, Öffnungsbereitschaft, Misstrauen, Alter, Ausbildungsgrad und Beziehungsdauer geeignete Prädiktoren darstellen für die Bereitschaft von Männern ein hormonelles Verhütungsmittel zu verwenden. Ebenso wurde untersucht, ob diese Variablen die Bereitschaft von Frauen vorhersagen können auf ihre Verhütung zu verzichten und auf den Partner zu vertrauen. Mittels eines Online Fragebogen wurden dazu die Daten von 126 Männern und 180 Frauen erhoben. Es zeigte sich, dass mit keiner der vermuteten Variablen eine Bereitschaft der Männer vorhergesagt werden konnte. Für die Gruppe der Frauen hingegen erwiesen sich die Bindungsqualität, die Öffnungsbereitschaft und das Misstrauen als vorhersagekräftige Prädiktoren. Für weitergehende Analysen wurden sowohl die Männer als auch die Frauen nach folgenden Kriterien aufgeteilt: Zugehörigkeit zu einer religiösen Gemeinschaft, Wohnsituation, Einkommen, Kinderwunsch und Beziehungssituation. Obwohl keine Indikatoren für die Gesamtgruppe der Männer gefunden wurden, sprachen sich über 65% für die Verwendung eines hormonellen Verhütungsmittels aus. Diese Diskrepanz lässt soziale Erwünschtheit beim Antwortverhalten der Männer vermuten.
description: This study was conducted to examine if the variables attachment quality, willingness to open up, distrust, age, level of education and relationship duration pose as valid predictors for the willingness of men to use a hormonal contraception. In addition to that, it was investigated if these variables could predict the willingness of women to forego their own contraceptive methods and trust in their partners. Therefore, data of 126 men and 180 women was collected via an online survey. It was shown, that willingness of men could not be predicted by any of the presumed variables. For women, on the other hand, attachment quality, willingness to open up and distrust could be identified as valid predictors. For further analysis both men and women were sorted according to the following criteria: affiliation to a religious group, housing situation, financial income, desire to have children and relationship status. Even though no indicators could be found for the entirety of the male sample, 65% of this group expressed a willingness to use hormonal contraceptives. This discrepancy suggests social desirability in the men’s response behavior.
title: Entwicklung einer Real-Time PCR-Methode zum Nachweis von Mohn-DNA in Lebensmitteln
Creators: name: Pesendorfer, Maria
Year: 2021

description: Lebensmittelallergien bedeuten für Betroffene eine große Einschränkung in der Lebensqualität, wobei Mohn-Samen ein besonderes Problem darstellen, da sie häufig „versteckt“ in Speisen vorkommen. Die Mohn-Allergie ist selten, führt jedoch häufig zu anaphylaktischen Reaktionen. Mohn zählt nicht zu den in der EU kennzeichnungspflichtigen 14 Lebensmittelallergenen. In dieser Diplomarbeit wurde ein Real-Time PCR-Assay zum Nachweis von Mohn-DNA in Lebensmitteln entwickelt, basierend auf einer bereits publizierten Dissertation. Nach der Optimierung der Primer- und Sonden-Konzentration wurde die Anwendbarkeit auf drei Sorten von Schlafmohn (Papaver somniferum) untersucht. Der Assay ermöglicht den Nachweis von Blaumohn, Graumohn und Weißmohn, wobei für Blaumohn eine Amplifikationseffizienz von 100,0 % ermittelt wurde. Die Nachweisgrenze lag für alle drei Mohn-Sorten bei einer DNA-Konzentration von 0,1 ng/µl. Der Real-Rime PCR-Assay erwies sich als spezifisch für Mohn, es wurde keine Kreuzreaktion mit Dinkelmehl, Roggenvollkornmehl, Weizenmehl, Reis, Haselnuss, Walnuss, Pinienkern, Muskatnuss, Pistazie, Karotte, Kartoffel, Ingwer, Rote Linse, Mais, Rosine, Zitrone, Ribisel, Pflaume, Mandel, Vanille, Zimt und Backhefe beobachtet. Zur Bestimmung der Nachweisgrenze in einer komplex zusammengesetzten Lebensmittelmatrix wurde ein Schokoladekuchenteig als Modell-Lebensmittel hergestellt. Im rohen Teig betrug die Nachweisgrenze 0,01 % Mohn, im gebackenen Teig 0,0058 % Mohn. Bei der Anwendung des Real-Time PCR Assays auf 14 kommerzielle Lebensmittel wurde Mohn in jedem der elf Mohnprodukte und in einem von drei Produkten, die laut Zutatenliste keinen Mohn enthielten, nachgewiesen.

description: We report variational Monte Carlo calculations for the spin-$\frac{1}{2}$ Heisenberg model on the kagome lattice in the presence of both nearest-neighbor $J_1$ and next-nearest-neighbor $J_2$ antiferromagnetic superexchange couplings. Our approach is based upon Gutzwiller projected fermionic states that represent a flexible tool to describe quantum spin liquids with different properties (e.g., gapless and gapped). We show that, on finite clusters, a gapped $\mathbb{Z}_{2}$ spin liquid can be stabilized in the presence of a finite $J_2$ superexchange, with a substantial energy gain with respect to the gapless $U(1)$ Dirac spin liquid. However, this energy gain vanishes in the thermodynamic limit, implying that, at least within this approach, the $U(1)$ Dirac spin liquid remains stable in a relatively large region of the phase diagram. For $J_2/J_1 \gtrsim 0.3$, we find that a magnetically ordered state with ${\bf q}={\bf 0}$ overcomes the magnetically disordered wave functions, suggesting the end of the putative gapless spin-liquid phase.

description: Toxoplasma gondii secretes protein effectors to subvert the human immune system sufficiently to establish a chronic infection. Relative to murine infections, little is known about which parasite effectors disarm human immune responses. Here, we used targeted CRISPR screening to identify secreted protein effectors required for parasite survival in IFNγ-activated human cells. Independent screens were carried out using 2 Toxoplasma strains that differ in virulence in mice, leading to the identification of effectors required for survival in IFNγ-activated human cells. We identify the secreted protein GRA57 and 2 other proteins, GRA70 and GRA71, that together form a complex which enhances the ability of parasites to persist in IFNγ-activated human foreskin fibroblasts (HFFs). Components of the protein machinery required for export of Toxoplasma proteins into the host cell were also found to be important for parasite resistance to IFNγ in human cells, but these export components function independently of the identified protein complex. Host-mediated ubiquitination of the parasite vacuole has previously been associated with increased parasite clearance from human cells, but we find that vacuoles from GRA57, GRA70, and GRA71 knockout strains are surprisingly less ubiquitinated by the host cell. We hypothesise that this is likely a secondary consequence of deletion of the complex, unlinked to the IFNγ resistance mediated by these effectors.
Energy dependence of light hypernuclei production in heavy-ion collisions from a coalescence and statistical-thermal model perspective

description: A comparison of light hypernuclei production, from UrQMD+coalescence and the thermal model, in heavy ion collisions over a wide range of beam energies and system sizes is presented. We find that both approaches provide generally similar results, with differences in specific details. Especially the ratios of hypertriton to $Λ$ are affected by both the source radius $Δr$ of the coalescence procedure as well as canonical effects. On the other hand, the double ratio $S_3$ is almost independent of canonical effects, which is in contrast to coalescence. Thus, both the beam energy dependence and centrality dependence of $S_3$ can be used to constrain the hypertriton source radius. To do so the currently available data is not yet sufficient. Elliptic flow is shown to be unaffected by the source size of the nuclei and an almost perfect mass scaling of the elliptic flow is observed. Our predictions further suggest that the existence of the H-dibaryon ($ΛΛ$) seems ruled out by ALICE data.

description: We consider the impact of Doppler noise models on the statistical robustness of the exoplanetary radial-velocity fits. We show that the traditional model of the Doppler noise with an additive jitter can generate large non-linearity effects, decreasing the reliability of the fit, especially in the cases when a correleated Doppler noise is involved. We introduce a regularization of the additive noise model that can gracefully eliminate its singularities together with the associated non-linearity effects. We apply this approach to Doppler time-series data of several exoplanetary systems. It demonstrates that our new regularized noise model yields orbital fits that have either increased or at least the same statistical robustness, in comparison with the simple additive jitter. Various statistical uncertainties in the parametric estimations are often reduced, while planet detection significance is often increased. Concerning the 55 Cnc five-planet system, we show that its Doppler data contain significant correlated ("red") noise. Its correlation timescale is in the range from days to months, and its magnitude is much larger than the effect of the planetary N-body perturbations in the radial velocity (these perturbations thus appear undetectable). Characteristics of the red noise depend on the spectrograph/observatory, and also show a cyclic time variation in phase with the public Ca II H & K and photometry measurements. We interpret this modulation as a hint of the long-term activity cycle of 55 Cnc, similar to the Solar 11-year cycle. We estimate the 55 Cnc activity period by $12.6\pm^{2.5}_{1.0}$ yrs, with the nearest minimum presumably expected in 2014 or 2015.

description: Two-particle scattering probabilities in tunneling scenarios with exchange interaction are analyzed with quasi-particle wave packets. Two initial one-particle wave packets (with opposite central momentums) are spatially localized at each side of a barrier. After impinging upon a tunneling barrier, each wave packet splits into transmitted and reflected components. When the initial two-particle anti-symmetrical state is defined as a Slater determinant any type of (normalizable) one-particle wave packet, it is shown that the probability of detecting two (identically injected) electrons at the same side of the barrier is different from zero in very common (single or double barrier) scenarios. In some particular scenarios, the transmitted and reflected components become orthogonal and the mentioned probabilities reproduce those values associated to distinguishable particles. These unexpected non-zero probabilities are still present when non-separable Coulomb interaction or non-symmetrical potentials are considered. On the other hand, for initial wave packets close to Hamiltonian eigenstates, the usual zero two-particle probability for electrons at the same side of the barrier found in the literature is recovered. The generalization to many-particle scattering probabilities with quasi-particle wave packets for low and high phase-space density are also analyzed. The far-reaching consequences of these non-zero probabilities in the accurate evaluation of quantum noise in mesoscopic systems are briefly indicated.

description: Neutron star (NS) masses and radii can be estimated from observations of photospheric radius-expansion X-ray bursts, provided the chemical composition of the photosphere, the spectral colour-correction factors in the observed luminosity range, and the emission area during the bursts are known. By analysing 246 X-ray bursts observed by the Rossi X-ray Timing Explorer from 11 low-mass X-ray binaries, we find a dependence between the persistent spectral properties and the time evolution of the black body normalisation during the bursts. All NS atmosphere models predict that the colour-correction factor decreases in the early cooling phase when the luminosity first drops below the limiting Eddington value, leading to a characteristic pattern of variability in the measured blackbody normalisation. However, the model predictions agree with the observations for most bursts occurring in hard, low-luminosity, 'island' spectral states, but rarely during soft, high-luminosity, 'banana' states. The observed behaviour may be attributed to the accretion flow, which influences cooling of the NS preferentially during the soft state bursts. This result implies that only the bursts occurring in the hard, low-luminosity spectral states can be reliably used for NS mass and radius determination.

title: Bestand und Entwicklung von Verdichtungspotenzialen in Bahnhofsnahbereichen entlang der Pottendorfer Linie
Creators: name: Niedrist, Hannah
Year: 2021

description: Die Stadtregion Wien ist, wie viele andere Stadtregionen, mit starkem Bevölkerungswachstum und einer damit einhergehenden, großen Nachfrage nach Wohnraum konfrontiert. Die daraus resultierende Siedlungsentwicklung durch Rahmensetzungen zu lenken, ist eine zentrale Aufgabe von Politik und Planung. Die Zielvorstellungen umfassen das Verhindern des Wachsens von Siedlungsgebieten in die Fläche sowie eine Verdichtung bestehender Siedlungsgebiete. Dabei ist es sowohl aus ökologischer als auch aus ökonomischer und planerischer Sicht sinnvoll, insbesondere Räume mit guter Anbindung an das öffentliche Verkehrsnetz zu verdichten. Diese Arbeit zeigt, wie groß das Potenzial ist, das in der Verdichtung von Bahnhofsnahbereichen der Pottendorfer S-Bahnlinie im südlichen Wiener Umland liegt. Auf insgesamt rund 35 Hektar freier, bereits als Bauland gewidmeter, Flächen könnte Wohnraum für über 1.800 Personen geschaffen und zahlreiche Betriebsgebäude errichtet werden – alleine im Umfeld eines 300-Meter-Fußwegs zu einem der Bahnhöfe. Der Vergleich mit im Jahr 2014 von Stefanie Döringer, Peter Görgl und Johannes Huemer erhobenen Daten ergibt, dass das Flächenpotenzial in den vergangenen Jahren nur wenig ausgeschöpft wurde und nur um etwa 17 Prozent gesunken ist. Dabei haben sich die zwölf Bahnhofsnahbereiche entlang der Pottendorfer Linie sehr unterschiedlich entwickelt.

description: Im Fokus vorliegender Arbeit steht die Analyse des gesellschaftspolitischen Diskurses über Änderungen im österreichischen Asylrecht am konkreten Beispiel der sogenannten „Asyl-Notverordnung“ von 2016. Nach der Einleitung und dem Überblick über den For-schungsstand werden das theoretische Rüstzeug und methodische Instrumentarium der Untersuchung vorgestellt. Als Materialgrundlage dienen ihr APA-Pressemeldungen politi-scher Parteien und NGOs zur „Notverordnung“ aus dem Zeitraum Jänner bis April 2016. Das umfangreiche Material wird einer eingehenden Diskursanalyse unterzogen, wobei sowohl Struktur- als auch Feinanalysen zum Einsatz gelangen. Hierbei zeigt sich, dass eine bereits 2015 einsetzende Verschiebung im Diskurs über Flucht und Asyl weiterwirkt und sich sukzessive verschärft. Mehrheitlich steht nicht mehr der Schutz der Geflüchteten im Fokus einer vermeintlich gelungenen Asylpolitik, sondern der Schutz nationalstaatlicher Interessen vor den als großteils unkontrollierbar dargestellten Massen an Geflüchteten.
description: This master thesis examines the socio-political discourse arising from changes to the Aus-trian asylum law using the so-called “Asyl-Notverordnung” from 2016 as the main case study. After the introduction and an overview of the current state of research, the theoreti-cal frame and methodological instruments used are presented. APA press releases from political parties and NGOs on the “Emergency Ordinance” from January to April 2016 serve as the empirical basis. This extensive material is subjected to a detailed discourse analysis, with structural as well as detailed analyses being applied to the corpus. The re-sults show that a shift in the discourse on flight and asylum that began in 2015 continues to have an impact on the Austrian political discourse and is gradually becoming more acute. The protection of refugees is no longer the focus of a supposedly successful Austrian asylum policy. Instead, the safeguarding of national interests from what is depicted as masses of refugees which are mainly described as uncontrollable has become the central part of the political narrative.

description: We study numerically the spectrum of the non-Hermitian effective Hamiltonian that describes the dipolar interaction of a gas of $N\gg 1$ atoms with the radiation field. We analyze the interplay between cooperative effects and disorder for both scalar and vectorial radiation fields. We show that for dense gases, the resonance width distribution follows, both in the scalar and vectorial cases, a power law $P(Γ) \sim Γ^{-4/3}$ that originates from cooperative effects between more than two atoms. This power law is different from the $ P(Γ) \sim Γ^{-1}$ behavior, which has been considered as a signature of Anderson localization of light in random systems. We show that in dilute clouds, the center of the energy distribution is described by Wigner's semicircle law in the scalar and vectorial cases. For dense gases, this law is replaced in the vectorial case by the Laplace distribution. Finally, we show that in the scalar case the degree of resonance overlap increases as a power law of the system size for dilute gases, but decays exponentially with the system size for dense clouds.

description: Thermal properties of asymmetric nuclear matter, including the temperature dependence of the symmetry energy, single-particle properties, and differential isospin fractionation, are investigated with different neutron-proton effective mass splittings using an improved isospin- and momentum-dependent interaction. In this improved interaction, the momentum-dependence of the isoscalar single-particle potential at saturation density is well fitted to that extracted from optical model analyses of proton-nucleus scattering data up to nucleon kinetic energy of 1 GeV, and the isovector properties, i.e., the slope of the nuclear symmetry energy, the momentum-dependence of the symmetry potential, and the symmetry energy at saturation density can be flexibly adjusted via three parameters $x$, $y$, and $z$, respectively. Our results indicate that the nucleon phase-space distribution in equilibrium, the temperature dependence of the symmetry energy, and the differential isospin fractionation can be significantly affected by the isospin splitting of nucleon effective mass.

description: The density-matrix renormalization group method has become a standard computational approach to the low-energy physics as well as dynamics of low-dimensional quantum systems. In this paper, we present a new set of applications, available as part of the ALPS package, that provide an efficient and flexible implementation of these methods based on a matrix-product state (MPS) representation. Our applications implement, within the same framework, algorithms to variationally find the ground state and low-lying excited states as well as simulate the time evolution of arbitrary one-dimensional and two-dimensional models. Implementing the conservation of quantum numbers for generic Abelian symmetries, we achieve performance competitive with the best codes in the community. Example results are provided for (i) a model of itinerant fermions in one dimension and (ii) a model of quantum magnetism.

title: Das Verständnis von Identität in den Postkolonialen Studien und dessen Mehrwert für den Geschichtsunterricht in einer pluralistisch verfassten Gesellschaft
Creators: name: Draxler, Sophie
Year: 2021

description: Die vorliegende Diplomarbeit geht der Frage nach, welche inhaltlichen Angebote zum Thema Identität und Kolonialismus in gegenwärtigen Schulbüchern der 3. Klasse AHS- Unterstufe bzw. Neue Mittelschule vorhanden sind. Dabei werden Text und Bild mit Hilfe der qualitativen Inhaltsanalyse nach Mayring untersucht. Hierzu erfolgt eine Festlegung von Analysekategorien, die das Material gliedern und aufteilen. Es werden vor allem die Module 2 (Begegnungen zwischen dem Eigenen und dem Fremden) und 8 (Identitäten) der Schulbücher untersucht. Im Anschluss kommt es zur Zusammenführung der Schulbuchinhalte und einer Gegenüberstellung mit Zugängen zu Identität und Kolonialismus der postkolonialen Studien. Diese haben bis dato kaum Eingang in pädagogische Diskurse gefunden, wobei sie Potenzial für rassismuskritische Ansätze und einem erweiterten Verständnis von Globalem Lernen haben. Die Analyse der Schulbücher zeigte, dass sich nur ansatzweise postkoloniale Denkweisen wiederfinden.
description: The present diploma thesis investigates the content-related offers on the topic of identity and colonialism in current school books of the 3rd grade AHS-lower level or new middle school. Text and images are examined according to Mayring's qualitative content analysis. For this purpose, analysis categories are defined that structure and divide the material. Above all, modules 2 (encounters between the self and the unfamiliar) and 8 (identities) of the school books are examined. This is followed by a merging of the textbook contents and a comparison with approaches to the identity and colonialism of postcolonial studies. To date, these have hardly found their way into pedagogical discourse, although they have the potential for approaches critical of racism and an expanded understanding of global learning. The analysis of the school books showed, that postcolonial ways of thinking can only be found to a limited extent.
title: Didaktische Überlegungen zur Erhöhung der Attraktivität wirtschaftlicher Themen im GW-Unterricht der Sekundarstufe I
Creators: name: Stocker, Lukas
Year: 2021

description: Ausgehend von der Problemstellung, nämlich dass einerseits eine mangelnde Thematisierung wirtschaftlicher Themen in den Schulen beklagt wird, andererseits aber eine Analyse der Lehrpläne für das Fach GW verdeutlicht, dass diese als verpflichtender Lehrstoff im Unterricht der Sekundarstufe I vorgesehen sind, stellt sich die Frage nach einer Attraktivierung des GW-Unterrichts unter den gegebenen Rahmenbedingungen. Ein qualitatives Experiment, bei dem zwei Gruppen ein und derselbe wirtschaftliche Themenbereich einmal mittels lehrstofforientierter und einmal mittels schülerorientierter Methoden vermittelt wurde, erbrachte klare Vorteile, was den bildenden Ertrag betrifft, zugunsten des schülerorientierten Ansatzes. Dieser fördert das Vertrauen der SchülerInnen in sich selbst, einen kritischeren Umgang mit finanziellen Mitteln und das Verständnis für wirtschaftliche Zusammenhänge. Empfohlen wird, den Einsatz schülerorientierter Methoden im GW-Unterricht zu forcieren und somit die Struktur des Unterrichts in seiner konventionellen Form zu ändern.

description: In der Masterarbeit „Der Statuenzyklus des Schönbrunner Parks und das druckgrafische Werk “Österreichs Merkwürdigkeiten die Bild- und Baukunst betreffend” von 1779“ soll geklärt werden, wie es zu der genannten Publikation von Johann Christian Friedrich Wilhelm Beyer im Rahmen des Gesamtprojektes „Schönbrunner Schlosspark“ kam. Wer waren die handelnden Personen bei der Herstellung und Veröffentlichung, in welchem Verlag ist die Publikation erschienen und in welcher Auflagenhöhe. Wie hat Beyer die Auswahl der Grafikkünstler, die aus Wien, Berlin und Stuttgart stammen, für seine Publikation vorgenommen und wie sind diese Künstler in der grafischen Kunst und der mitteleuropäischen Kunstlandschaft zu verorten. Es wird erörtert, ob und in welcher Tradition die druckgrafische Publikation steht und welche Intentionen Beyer mit der Herausgabe hätte haben können.
title: Fremdzuschreibungen und Positionierungsangebote für Schüler_innen im politisch-parlamentarischen Diskurs über Deutschförderklassen
Creators: name: Kirov-Sanchez, Michaela
Year: 2021

description: Die Diskussion über Schüler_innen mit Deutschförderbedarf nahm mit der Gesetzesnovelle zu Deutschförderklassen im Jahr 2018 an Fahrt an, wobei vor allem das Förderformat und mögliche Auswirkungen auf den Bildungsweg von Schüler_innen diskutiert wurden. Das Ziel dieser Arbeit ist es, den Diskurs über Deutschförderklassen im österreichischen Parlament anhand einer Key Incident Analyse zu analysieren, um die in diesem Zusammenhang stattfindenden Zuschreibungen und Positionierungsangebote festzuhalten und zu hinterfragen. Diesbezüglich wird die Bedeutung von Diskurs für Subjekte und soziale Ordnungen erklärt und mit diesem Verständnis die Basis für die Methode der Key Incident Analyse gelegt. Anschließend wird (natio-ethno-kulturelle) Zugehörigkeit entlang von Sprache diskutiert und ein Abriss zur österreichischen Migrations- und Bildungspolitik mit Fokus auf Sprache gegeben. In Bezug auf Zugehörigkeit werden anschließend Theorien zur Differenzsetzung von Personen ebenfalls mit einem Fokus auf Sprache hinzugezogen. In Bezug auf soziale Ordnung, Zugehörigkeit und Differenzsetzung werden Reden aus dem österreichischen Parlament zu Annahme oder Ablehnung der Gesetzesnovelle analysiert, um Fremdzuschreibungen und davon ableitbare Positionierungsangebote für Schüler_innen festzuhalten. Abschließend werden die Ergebnisse der Analyse aufgezeigt und diskutiert, welche Positionierungsangebote die Schüler_innen im politisch-parlamentarischen Diskurs von Politiker_innen erhalten und eine kurze Empfehlung für das Sprechen über Schüler_innen und deren Sprachenkenntnisse gegeben.

description: Our contribution will discuss the development and application of standards to increase interoperability of data from archaeological mortuary contexts. More specifically, we will present the development of the ARIADNE Mortuary Data Application Profile (Aspöck, Theodoridou and Felicetti 2021), that is an extension of the ARIADNE project ontology (Richards, Felicetti, Meghini & Theodoridou 2020) and based on the CIDOC CRM (Doerr 2003). Together with other Application Profiles, it will be the basis for cross querying datasets from different providers via the ARIADNE infrastructure.

description: The main objective of this study was to define the influence of silica aerogels (SAs) through the sol-gel method and oil properties on 3 D weft-knitted spacer fabric sorbents for oil wicking, spreading, swelling, and interception properties (used as an interceptor barrier for vegetable and engine oil in static and dynamic water tests). SEM, FTIR-ATR, XRD, and BET tests of fabric sorbents were studied to explain the impact of SAs. The oil spreading rate exposed that the higher pore diameter, specific surface area, surface roughness, silica add-on %, water contact angle, and lower surface energy of sorbents exhibited the higher wicking height of 91.5 mm and 85.6 mm for vegetable oil and engine oil, respectively (TS 5). Similarly, the static intercepting experiment showed the higher oil interception efficiency of 99.01% and 99.89% with the initial leaking time of 24 min and 26 min for vegetable oil and engine oil, respectively. Likewise, the dynamic intercepting test (with water flow rates of 150 mL/s) revealed the higher oil interception efficiency of 98.89% and 99.77% with the initial leaking time of 10 min and 12 min, individually. Moreover, the treated sample showed the lowest oil swelling thickness (0.2 ± 0.1%) whereas the untreated sample showed the highest oil swelling thickness (7.3 ± 0.5%). The experimental results discovered that silica aerogels, fabric properties, and oil features had a substantial impact on oil wicking, spreading, swelling, static, and dynamic tests. Thus, these fabrics could be appropriate for industrial uses as eco-friendly oil clean-up sorbent.
Search for physics beyond the standard model in final states with a lepton and missing transverse energy in proton-proton collisions at sqrt(s) = 8 TeV

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search for new physics in proton-proton collisions having final states with an electron or muon and missing transverse energy is presented. The analysis uses data collected in 2012 with the CMS detector, at an LHC center-of-mass energy of 8 TeV, and corresponding to an integrated luminosity of 19.7 inverse femtobarns. No significant deviation of the transverse mass distribution of the charged lepton-neutrino system from the standard model prediction is found. Mass exclusion limits of up to 3.28 TeV at a 95% confidence level for a W' boson with the same couplings as that of the standard model W boson are determined. Results are also derived in the framework of split universal extra dimensions, and exclusion limits on Kaluza-Klein W[KK,2] states are found. The final state with large missing transverse energy also enables a search for dark matter production with a recoiling W boson, with limits set on the mass and the production cross section of potential candidates. Finally, limits are established for a model including interference between a left-handed W' boson and the standard model W boson, and for a compositeness model.

description: Crises such as the COVID-19 pandemic continuously threaten our world and emotionally affect billions of people worldwide in distinct ways. Understanding the triggers leading to people's emotions is of crucial importance. Social media posts can be a good source of such analysis, yet these texts tend to be charged with multiple emotions, with triggers scattering across multiple sentences. This paper takes a novel angle, namely, emotion detection and trigger summarization, aiming to both detect perceived emotions in text, and summarize events and their appraisals that trigger each emotion. To support this goal, we introduce CovidET (Emotions and their Triggers during Covid-19), a dataset of ~1,900 English Reddit posts related to COVID-19, which contains manual annotations of perceived emotions and abstractive summaries of their triggers described in the post. We develop strong baselines to jointly detect emotions and summarize emotion triggers. Our analyses show that CovidET presents new challenges in emotion-specific summarization, as well as multi-emotion detection in long social media posts.
