description: This review was born as notes for a lecture given at the YRIS school on integrability in Durham, in the summer of 2015. It deals with a beautiful method, developed in the mid-nineties by V.V. Bazhanov, S.L. Lukyanov and A.B. Zamolodchikov and, as such, called BLZ. This method can be interpreted as a field theory version of the quantum inverse scattering (QIS), also known as algebraic Bethe ansatz (ABA). Starting with the case of conformal field theories (CFT) we show how to build the field theory analogues of commuting transfer T matrices and Baxter Q-operators of integrable lattice models. These objects contain the complete information of the integrable structure of the theory, viz. the integrals of motion, and can be used, as we will show, to derive the thermodynamic Bethe ansatz (TBA) and non-linear integral (NLIE) equations. This same method can be easily extended to the description of integrable structures of certain particular massive deformations of CFTs; these, in turn, can be described as quantum group reductions of the quantum sine-Gordon model and it is an easy step to include this last theory in the framework of BLZ approach. Finally we show an interesting and surprising connection of the BLZ structures with classical objects emerging from the study of classical integrable models via the inverse scattering transform method. This connection goes under the name of ODE/IM correspondence and we will present it for the specific case of quantum sine-Gordon model only.

description: In this work, the dynamics of a self-propelled stochastic particle under the influence of an axisymmetric light field was experimentally studied. The particle under consideration has the main characteristic of carrying a light sensor in an eccentric location. For the chosen experimental conditions, the emerging trajectories were orbital, and, more interestingly, they presented two preferential radial distances. A mathematical model incorporating the key experimental components was introduced. By means of numerical simulations and theoretical analysis, it was found that, in addition to the orbiting behavior, the sensor location could produce trapped or diffusive behaviors. Furthermore, the study revealed that stochastic perturbation and the eccentric location of the sensor are responsible for inducing bistability in the orbital trajectories, in agreement with the experimental observations.

description: Die Klimakrise nimmt einen immer grösseren Stellenwert in der Gesellschaft ein. Die vorliegende Forschungsarbeit mit dem Titel «Die Soziale Arbeit in Zeiten der Klimakrise - Eine kleine Forschungsarbeit zum umweltpolitischen Mandat der Sozialen Arbeit», verfasst von Maria Gehlhaar, befasst sich mit den Auswirkungen der Klimakrise auf die Gesellschaft und möglichen Handlungsansätzen für die Soziale Arbeit. Die Arbeit ist nach dem Erklärungsmodell multipler Gesellschaftskrisen nach Gregor Husi aufgebaut. Anhand der Fragen «Welchen Einfluss hat die Klimakrise auf unsere Gesellschaft?» und «Welche Rolle nimmt die Soziale Arbeit in Zeiten der Klimakrise ein?» werden die Ursachen gesellschaftlicher und kultureller Probleme dargestellt und anschliessend die Rolle der Sozialen Arbeit aufgezeigt. Im nächsten Schritt wird ein präventiver Ansatz anhand eines umweltpolitischen Mandats der Sozialen Arbeit dargelegt. Es folgt eine Rollenklärung der Sozialen Arbeit im Schweizer Politiksystem. Um ein aktuelles Bild der politischen Zusammenhänge der Klimakrise und der Sozialen Arbeit zu erlangen, wurde eine qualitative Forschung durchgeführt. Dabei soll die Frage «Wie soll sich die Soziale Arbeit in der Umweltpolitik positionieren?» beantwortet werden. Für die Forschung wurden Kommunalpolitiker*innen mittels Interviews befragt. Abschliessend wurde der Bogen zur Sozialen Arbeit geschlagen. Die Forschungsarbeit hat gezeigt, dass die Klimakrise einen Einfluss auf die Profession der Sozialen Arbeit hat. Die Soziale Arbeit hat vielseitige Handlungsmöglichkeiten, um die Gesellschaft zu sensibilisieren und die Politik auf die Thematik aufmerksam zu machen.

description: The two-dimensional electron liquid, at the (001) interface between band insulators {L}a{A}l{O}$_3$ and {S}r{T}i{O}$_3$, undergoes Lifshitz transition as the interface is doped with carriers. At a critical carrier density, two new orbitals populate at the Fermi level, with a concomitant change in the Fermi surface topology. Using dynamical mean-field theory, formulated within a realistic three-orbital model, we study the influence of the Lifshitz transition and local electron correlations on the transport properties. We look at the thermal conductivity, optical conductivity, Seebeck coefficient and angle resolved photoemission spectra and find that at a critical density, both the thermal and dc conductivities rise sharply to higher values while the Seebeck coefficient shows a cusp. The inter-orbital electron-electron interaction transfers spectral weight near the $Γ$ point towards lower energy, thereby reducing the critical density. In the presence of external magnetic field, the critical density further reduces due to exchange splitting. Beyond a sufficiently large field, multiple cusps appear in the Seebeck coefficient revealing multiple Lifshitz transitions.

Revisiting the pion Regge trajectories

description: We propose a model-independent ansatz $M={β_x}\left(x+c_0\right)^ν+c_1$ ($x=l,\,n_r$) and then use it to fit the orbital and radial pion Regge trajectories without the preset values. It is shown that nonzero $c_1$ is reasonable and acceptable. Nonzero $c_1$ gives an explanation for the nonlinearity of the pion Regge trajectories in the usually employed $(M^2,\,x)$ plane. As $m_R$ or $c_1$ is chosen appropriately, both the orbital and radial pion Regge trajectories are linear in the $((M-m_R)^2,\,x)$ plane whether the $π^0$ is included or not on the Regge trajectories. The fitted pion Regge trajectories suggest $0.45\leν\le0.5$, which indicates the confining potential $r^a$ with $9/11{\le}a\le1$. Moreover, it is illustrated in the appendix B that $m_R$ can be nonzero for the light nonstrange mesons. We present discussions in the appendix A on the structure of the Regge trajectories plotted in the $(M,\,x)$ plane and on the structure of the Regge trajectories in the $((M-m_R)^2,\,x)$ plane based on the potential models and the string models.

Statistical Properties of Radio Halos in Galaxy Clusters and Origin of Seed Electrons for Reacceleration

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: One of the most promising mechanisms for producing radio halos (RHs) in galaxy clusters is the reacceleration of cosmic-ray electrons by turbulences. However, the origin of the seed electrons for the reacceleration is still poorly constrained. In the secondary scenario, most of the seed electrons are injected via collision of proton cosmic-rays, while non-thermal electrons are directly injected in the primary scenario. In this paper, we examine the two scenarios for the seed electrons with the observed statistical properties of RHs, combining two methods: following the temporal evolutions of the electron energy and radial distributions in a cluster, and the merger history of clusters. We find that the RH lifetime largely depends on the seed origin, as it could be longer than the cosmological timescale in the secondary scenario. We study the condition for the onset of RHs with the observed RH fraction and the RH lifetime we obtained, and find that long-lived RHs in the secondary scenario should be originated from major mergers with a mass ratio of $ξ\sim0.1$, while the short lifetime in the primary scenario requires more frequent onsets by minor mergers with $ξ\sim0.01$. Our simple model of the turbulence acceleration can reproduce the observed radio luminosity-mass relation. The RH luminosity functions we obtained suggest that the expected RH number count with the ASKAP survey will detect $\approx10^3$ RHs in both the scenarios.

Geflüchtete Eritreer und Eritreerinnen in der Schweiz: Hintergrundwissen für Sozialarbeitende im Kontext Migration – eine Annäherung
Creators: name: Gerber, Deborah
Publisher: name: Zenodo
Year: 2023

description: Seit 2006 zählt Eritrea zu einer der häufigsten Herkunftsnationen von Asylgesuchstellenden in der Schweiz. Sowohl die Flucht als auch die Ankunft in der Schweiz kann für die geflüchteten Menschen zu individuell und strukturell bedingten Problemlagen führen, wodurch sie zu Adressaten und Adressatinnen der Sozialen Arbeit werden können. Gemäss verschiedenen Autorinnen und Autoren ist es für Sozialarbeitende von grosser Relevanz, Wissen über die Gründe und Folgen von Migration aufzubauen, um eine bestmögliche Unterstützung leisten zu können. In dieser Literaturarbeit wird deshalb der Frage «Welche Schlussfolgerungen ergeben sich aus dem rechtlichen und migrationsspezifischen Wissen über geflüchtete Menschen aus Eritrea für die Soziale Arbeit in der Schweiz?» nachgegangen. Dazu wird die allgemeine soziale, politische und wirtschaftliche Situation in Eritrea aufgezeigt und mit einem spezifischen Fokus auf den eritreischen Nationaldienst ergänzt. Dieses Hintergrundwissen wird mithilfe von Migrationstheorien, unter anderem den «Push- und Pull-Faktoren», der «Cumulative Causation» und der «Transnationalen Migration» eingeordnet, womit Erklärungshypothesen für die Flucht aus Eritrea erstellt werden können. So zeigt sich, dass die Flucht aus Eritrea in die Schweiz mit der monokausalen Erklärung der Flucht vor dem eritreischen Nationaldienst nur unzureichend erklärt werden kann. Mit dem besseren Verständnis zur Fluchtmigration aus Eritrea in die Schweiz können Sozialarbeitende auf individueller und gesellschaftlicher Ebene gezielter intervenieren, um die Lebenssituation der geflüchteten Menschen zu verbessern.

description: We compute fluctuation-induced (Casimir) forces for classical systems after a temperature quench. Using a generic coarse-grained model for fluctuations of a conserved density, we find that transient forces arise even if the initial and final states are force-free. In setups reminiscent of Casimir (planar walls) and van der Waals (small inclusions) interactions, we find comparable exact universal expressions for the force. Dynamical details only scale the time axis of transient force curves. We propose that such quenches can be achieved, for instance, in experiments on active matter, employing tunable activity or interaction protocols.

description: The first direct detection of gravitational waves was made in late 2015 with the Advanced LIGO detectors. By prior arrangement, a worldwide collaboration of electromagnetic follow-up observers were notified of candidate gravitational wave events during the first science run, and many facilities were engaged in the search for counterparts. No counterparts were identified, which is in line with expectations given that the events were classified as black hole - black hole mergers. However these searches laid the foundation for similar follow-up campaigns in future gravitational wave detector science runs, in which the detection of neutron star merger events with observable electromagnetic counterparts is much more likely. Three alerts were issued to the electromagnetic collaboration over the course of the first science run, which lasted from September 2015 to January 2016. Two of these alerts were associated with the gravitational wave events since named GW150914 and GW151226. In this paper we provide an overview of the Liverpool Telescope contribution to the follow-up campaign over this period. Given the hundreds of square degree uncertainty in the sky position of any gravitational wave event, efficient searching for candidate counterparts required survey telescopes with large (~degrees) fields-of-view. The role of the Liverpool Telescope was to provide follow-up classification spectroscopy of any candidates. We followed candidates associated with all three alerts, observing 1, 9 and 17 candidates respectively. We classify the majority of the transients we observed as supernovae.

description: Search for New Physics beyond the Standard Model is the main direction in particle physics nowadays. There are several experimental hints of New Physics. The most statistically significant (5-6$σ$) are the hints of eV mass scale sterile neutrinos. They come from antineutrino disappearance in reactor experiments, $ν_e$ disappearance in experiments with very powerful radioactive sources, and electron (anti)neutrino appearance in the muon (anti)neutrino beams. Very important results in this field were obtained in 2021 by the BEST, MicroBooNE, and Neutrino-4 collaborations as well as by several other experiments. However, the situation is still or maybe even more controversial. We review these indications of New Physics and prospects for the next few years with the emphasis on reactor experiments.
Impacts of stellar evolution and dynamics on the habitable zone: The role of rotation and magnetic activity

description: In this article, we aim to provide the community with the dependence of the habitable zone upon the stellar mass, metallicity, rotation, and for various prescriptions of the limits of the habitable zone. We use the STAREVOL code to study the evolution of the habitable zone and of the continuously habitable zone limits. Mass and metallicity are the stellar parameters that have the most dramatic effects on the habitable zone limits. Conversely, for a given stellar mass and metallicity, stellar rotation has only a marginal effect on these limits and does not modify the width of the habitable zone. The evolution of the habitable zone limits is also correlated to the evolution of the stellar activity (through the Rossby number) that depends on the stellar mass considered. While the magnetic activity has negligible consequence in the case of more massive stars, these effects may have a strong impact on the habitability of a planet around M dwarf stars. Thus, stellar activity cannot be neglected and may have strong impacts on the development of life during the early stage of the continuously habitable zone phase of low-mass stars. Using observed trends of stellar magnetic field strength we also constrain the planetary magnetic field (at the zero order) required for a sufficient magnetospheric protection during the whole stellar evolution. We explicit for the first time the systematic dependence of planet habitability on stellar parameters along the full evolution of low- and intermediate-mass stars. These results can be used as physical inputs for a first order estimation of exoplanetary habitability.

description: We present a simple and effective approach for posterior uncertainty quantification in deep operator networks (DeepONets); an emerging paradigm for supervised learning in function spaces. We adopt a frequentist approach based on randomized prior ensembles, and put forth an efficient vectorized implementation for fast parallel inference on accelerated hardware. Through a collection of representative examples in computational mechanics and climate modeling, we show that the merits of the proposed approach are fourfold. (1) It can provide more robust and accurate predictions when compared against deterministic DeepONets. (2) It shows great capability in providing reliable uncertainty estimates on scarce data-sets with multi-scale function pairs. (3) It can effectively detect out-of-distribution and adversarial examples. (4) It can seamlessly quantify uncertainty due to model bias, as well as noise corruption in the data. Finally, we provide an optimized JAX library called {\em UQDeepONet} that can accommodate large model architectures, large ensemble sizes, as well as large data-sets with excellent parallel performance on accelerated hardware, thereby enabling uncertainty quantification for DeepONets in realistic large-scale applications.

Interne Meldestellen in der institutionellen Behindertenhilfe als Lösung zur Gewaltprävention? Eine qualitative Untersuchung
Creators: name: Good, Katharina

Year: 2023

description: Je mehr Assistenz ein Mensch braucht, desto höher ist sein Risiko, Gewalt zu erfahren (BASGK, 2019, S. 20). Zudem konnten bei fast einem Drittel der Erwachsenen mit kognitiver Beeinträchtigung regelmässig herausfordernde Verhaltensweisen (HeVe) beobachtet werden, darunter häufig verbale Aggressionen und Selbstverletzungen (Lustenberger et al., 2019, S. 81). Institutionen der Behindertenhilfe sind somit nicht nur Bereiche des alltäglichen Lebens und der Förderung, sondern auch Orte, in denen Gewalt und Grenzverletzungen kumuliert auftreten können; auch gegenüber Angestellten (Krüger et al., 2023, S. 107). Mehrere Institutionen verpflichten sich selbst, eine Präventions- und Meldestelle (P&M) zu führen (Arbeitsgruppe Prävention, 2022a). Der Bundesrat empfiehlt nun, die P&M flächendeckend einzuführen (2023, S. 42). Die Forschung über deren Nutzen steht jedoch am Anfang und bedarf weiterer Aufmerksamkeit. In der vorliegenden Arbeit wurde zuerst anhand der Fachliteratur beschrieben, welches die häufigsten Formen von Gewalt in Institutionen sind und welche Ursachen hierfür vorliegen können. Wichtig ist, dass sowohl Vorfälle von Angestellten, Klient:innen als auch von externen Personen berücksichtigt wurden. Danach wurden, vermittelt über den Verband Anthrosocial, Betreiber:innen von drei institutionsinternen und einer externen P&M interviewt. Dies führte zu vier Grundsätzen und fünf Empfehlungen. Sie richten sich an Institutionen, um die Gewaltprävention zu stärken – aber auch an die Kantone, um verbindliche Richtlinien zu überprüfen.

description: Quantum key distribution protocols are known to be vulnerable against a side channel attack that exploits the time difference in detector responses used to obtain key bits. The recommended solution against this timing side channel attack is to use a large time bin width instead of high resolution timing information. Common notion is that using a large bin width reduces the resolution of detector responses, hence supposedly minimizes the information leakage to an eavesdropper. We challenge this conventional wisdom, and demonstrate that increasing the bin width does not monotonically reduce the mutual information between the key bits and the eavesdropper's observation of detector responses. Instead of randomly increasing the bin width, it should be carefully chosen because the mutual information fluctuates with respect to the bin width. We also examined the effect of full width half maximums (FWHMs) of the detectors responses on the mutual information and showed that decreasing the FWHM increases the mutual information. Lastly, the start time of binning is also shown to be important in binning process and the mutual information fluctuates periodically with respect to it.

Effect of disorder on the competition between nematic and superconducting order in FeSe

description: Crystalline FeSe is known to display strong nematic order below a weak tetragonal-orthorhombic structural transition around $T_s\sim 90$K, and a superconducting transition at $T_c\sim 9K$. Recently, it was shown that electron irradiation, which creates pointlike potential scattering defects, has the surprising effect of enhancing $T_c$ while suppressing $T_s$. Here we discuss a possible scenario for such an effect, which postulates a competition between $s_\pm$ superconductivity and nematic order. The transition to the nematic state is modeled by a mean field theory of a $d$-wave Pomeranchuk instability, together with a Cooper pairing interaction in both one- and multiband models. The effect of nonmagnetic impurities on both orders is treated on equal footing within the Born approximation. We find evidence that disorder can indeed enhance $T_c$ while suppressing the competition with nematic order, but only in a multiband situation. We discuss our results in the context of experimental data on FeSe crystals.

description: Non-Hermitian skin effect (NHSE) in non-Hermitian lattice systems, associated with a point gap on the complex energy plane, has attracted great theoretical and experimental interest. Much less is studied on the so-called second-order non-Hermitian skin effect, where the bulk does not support a point gap but localization at the corner still occurs. This work discovers a class of hybrid skin-topological modes as the second-order non-Hermitian skin effect without asymmetric couplings. Specifically, by only adding gain/loss to two-dimensional Chern insulators and so long as the gain/loss strength does not close the line gap, all the topological edge states are localized at one corner under the open boundary condition, with the bulk states extended. The resultant non-Hermitian Chern bands can be still topologically characterized by Chern numbers, whereas the hybrid skin-topological modes are understood via some auxiliary Hermitian systems that belong to either intrinsic or extrinsic second-order topological insulator phases. By proposing an innovative construction of auxiliary Hamiltonian, our generic route to hybrid skin-topological modes is further successfully extended to nonequilibrium topological systems with gain and loss, where the anomalous Floquet band topology is no longer captured by band Chern numbers. The extension thus leads to the intriguing finding of nonequilibrium hybrid skin-topological modes. In addition to offering a straightforward route to experimental realization of hybrid topological-skin effects, this study also opens up a promising perspective for the understanding of corner localization by revealing the synergy of three important concepts, namely, non-Hermitian topological insulator, second-order non-Hermitian skin effect, and second-order topological insulator.

description: We present a general approach to derive Lindblad master equations for a subsystem whose dynamics is coupled to dissipative bosonic modes. The derivation relies on a Schrieffer-Wolff transformation which allows to eliminate the bosonic degrees of freedom after self-consistently determining their state as a function of the coupled quantum system. We apply this formalism to the dissipative Dicke model and derive a Lindblad master equation for the atomic spins, which includes the coherent and dissipative interactions mediated by the bosonic mode. This master equation accurately predicts the Dicke phase transition and gives the correct steady state. In addition, we compare the dynamics using exact diagonalization and numerical integration of the master equation with the predictions of semiclassical trajectories. We finally test the performance of our formalism by studying the relaxation of a NOON state and show that the dynamics captures quantum metastability beyond the mean-field approximation.

description: We study the nonequilibrium quantum phase transition of an Ising chain in a dissipative cavity driven by an external transverse light field. When driving and dissipation are in balance, the system can reach a nonequilibrium steady state which undergoes a super-radiant phase transition as the driving strength increases. Interestingly, the super-radiant field changes the effective bias of the Ising chain in return and drives its own transition between the ferromagnetic and paramagnetic phase. We study the rich physics in this system with sophisticated behavior, and investigate important issues in its dynamics such as the stability of the system and criticality of the phase transition.

description: We consider two independent identical diffusion processes that annihilate upon meeting in order to study their conditioning with respect to their first-encounter properties. For the case of finite horizon $T<+\infty$, the maximum conditioning consists in imposing the probability $P^*(x,y,T ) $ that the two particles are surviving at positions $x$ and $y$ at time $T$, as well as the probability $γ^*(z,t) $ of annihilation at position $z$ at the intermediate times $t \in [0,T]$. The adaptation to various conditioning constraints that are less-detailed than these full distributions is analyzed via the optimization of the appropriate relative entropy with respect to the unconditioned processes. For the case of infinite horizon $T =+\infty$, the maximum conditioning consists in imposing the first-encounter probability $γ^*(z,t) $ at position $z$ at all finite times $t \in [0,+\infty[$, whose normalization $[1- S^*(\infty )]$ determines the conditioned probability $S^*(\infty ) \in [0,1]$ of forever-survival. This general framework is then applied to the explicit cases where the unconditioned processes are respectively two Brownian motions, two Ornstein-Uhlenbeck processes, or two tanh-drift processes, in order to generate stochastic trajectories satisfying various types of conditioning constraints. Finally, the link with the stochastic control theory is described via the optimization of the dynamical large deviations at Level 2.5 in the presence of the conditioning constraints that one wishes to impose.

description: Using the sensitivity of magneto-induced second harmonic generation to spin currents (SC), we demonstrate in Fe/Au/Fe/MgO(001) pseudo spin valves the generation of 250 fs-long SC pulses. Their temporal profile indicates that superdiffusive hot electron transport across a sub-100~nm Au layer is close to the ballistic limit and the pulse duration is primarily determined by the thermalization time of laser-excited hot carriers in Fe. Considering the calculated spin-dependent Fe/Au interface transmittance we conclude that a non-thermal spin-dependent Seebeck effect is responsible for the generation of ultrashort SC pulses. We also show that hot electron spins rotate upon interaction with non-collinear magnetization at the Au/Fe interface, which holds high potential for future spintronic devices.

description: Topological phononic insulators are the counterpart of three-dimensional quantum spin Hall insulators in phononic systems and, as such, their topological surfaces are characterized by Dirac cone-shaped gapless edge states arising as a consequence of a bulk-boundary correspondence. We propose a theoretical framework for the possible superconducting phase in these materials, where the attractive interaction between electrons is mediated by topological phonons in nontrivial boundary modes. Within the BCS limit, we develop a self-consistent two-band gap equation, whose solutions show that the superconducting critical temperature has a non-monotonic behaviour with respect to the phononic frequency in the Kramers-like point. This remarkable behaviour is produced by a resonance, that occurs when electrons and phonons on the topological surfaces have the same energy: this effectively increases the electron-phonon interaction and hence the Cooper pair binding energy, thus establishing an optimal condition for the superconducting phase. With this mechanism, the $T_{c}$ can be increased by well over a factor two, and the maximum enhancement occurs in the degenerate phononic flat-band limit.

Homonationalistisch geprägte Diskurse im Kontext der Offenen Jugendarbeit: Eine qualitative Forschungsarbeit
Creators: name: Müller, Nives

Publisher: name: Zenodo
Year: 2023

description: Ausgangspunkt dieser Bachelor-Thesis bildet das Konzept Homonationalismus. Dieses wird anhand einer theoretischen Rahmung auf den Kontext der Offenen Jugendarbeit [OJA] bezogen. Hierbei werden hegemoniale Diskurse zu Sexualität und Queerness sowie deren gesellschaftlichen Auswirkungen beleuchtet. Diese zeigen sich darin, dass ›der Westen‹ als ›fortschrittlich und queerfreundlich‹ gilt, während durch Prozesse des Otherings Personengruppen von ›nicht-westlichen‹ Nationen als ›queerfeindlich‹ eingestuft werden. Anhand des Homonormativitätskonzepts wird aufgezeigt, wie bestimmte Queers in die Gesellschaft integriert werden und ›andere‹, rassifizierte, migrantisierte und/oder muslimische queere Subjekte unsichtbar bleiben. Jene Konstruktionen prägen die Lebensrealitäten von Adressat:innen, womit sich die Praxisrelevanz für die OJA zeigt. Inwiefern diese im Diskurs der Fachpersonen (de)konstruiert werden, wurde in folgender Forschungsarbeit untersucht. Als methodische Herangehensweise wurden Interviews mit Fachpersonen durchgeführt und anhand einer Diskursanalyse ausgewertet. Dabei wurden unterschiedliche homonationalistische Prägungen erkennbar, wie bspw. das Kulturalisieren von Queerfeindlichkeit oder indem queerfeindliche Aussagen von migrantisierten Jugendlichen negativer interpretiert wurden als von ›schweizerischen‹. Dazu wurden u.a. folgende Handlungsempfehlungen ausgearbeitet: Die Reflexion von Ein- und Ausschlussmechanismen, das Dekonstruieren von Norm- und Machtverhältnissen sowie das Entwickeln von (mehrfach-) diskriminierungssensiblen Arbeitsweisen.

description: The gamma-ray emission from Starburst and Starforming Galaxies (SBGs and SFGs) strongly suggest a correlation between star-forming activity and gamma-ray luminosity. However, the very nature of cosmic-ray (CR) transport and the degree of their confinement within SBG cores are still open questions. We aim at probing the imprints left by CR transport on gamma-ray and neutrino observations of point-like SFGs and SBGs, looking into quantitative ways to discriminate among different transport models. Moreover, following the reported scenarios, we quantitatively assess the SBGs and SFGs contribution to the Extra-galactic Gamma-Ray Background (EGB data) and the IceCube diffuse observations (HESE data). We analyse the 10-year Fermi-LAT spectral energy distributions of 13 nearby galaxies with two different CR transport models, taking into account the corresponding IR and UV observations. We generate mock gamma-ray data to simulate the CTA performance in detecting these sources. In the way, we propose a test to discriminate between the two CR models, quantifying the statistical confidence at which one model can be preferred over the other. We point out that current data already give a slight preference to CR models which are dominated by advection in their nucleus. Moreover, we show that CTA will allow us to firmly disfavour models dominated by diffusion over self-induced turbulence, compared to advection-dominated models, with Bayes factors which can be as large as $10^7$ for some of the SBGs. Finally, we estimate the diffuse gamma-ray and neutrino fluxes of SFGs and SBGs, showing that they can explain $25\%$ of the diffuse HESE data, while remaining consistent with gamma-ray limits on non-blazar sources.

title: Krieg, Trauma, Genre: eine kritische Untersuchung zweier Tragikomödien, "Lepa sela lepo gore" (Srdjan Dragojević, SRB 1996) und "Turneja" (Goran Marković, SRB 2008) mit dem Hintergrund der Jugoslawienkriege

description: Mit der zentralen Frage danach, wie und wo die Verbindungen zwischen Krieg, Krise und Tragikomödie auf dem Gebiet des heutigen Ex-Jugoslawiens zu erkennen sind, versucht diese Arbeit anhand einer literarischen Diskursanalyse sowie der Analyse zweier Filme – Lepa sela lepo gore und Turneja –eine Antwort darauf zu geben. Die komplexe Verflechtung des Historischen, Psychologischen und Filmischen bedarf zunächst eines separaten Einblicks in alle drei Disziplinen, um diese schließlich miteinander im Rahmen filmischer Kontexte verknüpfen zu können. Die Komplexität der Thematik spiegelt sich in den ebenso komplexen filmischen Strukturen, ob der Zeit- oder Narrationsebenen, wider. Die Tragikomödie wird als eine Zugangsart zu und Auseinandersetzungsmöglichkeit mit den durch Krieg entstandenen kollektiven Traumata verstanden. Ihr wird die potenzielle Kraft der Heilung zugesprochen, indem sie tragische Erfahrungen in einem humoristischen Kontext verpackt und so wiedergibt.
