description: We establish an equivalence between infinitely many asymptotically stable periodic solutions and subsumed homoclinic connections for $N$-dimensional piecewise-linear continuous maps. These features arise as a codimension-three phenomenon. The periodic solutions are single-round: they each involve one excursion away from a central saddle-type periodic solution. The homoclinic connection is subsumed in the sense that one branch of the unstable manifold of the saddle solution is contained entirely within its stable manifold. The results are proved by using exact expressions for the periodic solutions and components of the stable and unstable manifolds which are available because the maps are piecewise-linear. We also describe a practical approach for finding this phenomenon in the parameter space of a map and illustrate the results with the three-dimensional border-collision normal form.

description: Die vorliegende Arbeit mit dem Titel „Tod der Seele. Eine Auseinandersetzung mit dem Konzept postmortaler Fortexistenz an ausgewählten Beispielen im Ethikunterricht“ beschäftigt sich im ersten Teil mit einer Heranführung an den Begriff des Todes und der unterschiedlichen Konzepte von Seele und ihrem Weiterleben. Hierbei werden die verschiedenen Ansätze dargestellt und voneinander abgegrenzt. In einem Literaturteil folgt die Auseinandersetzung mit den Gedanken der dafür gewählten Philosophen Leibniz und Feuerbach. Dafür werden jene Texte und Schriften, die sich mit dem Thema der Unsterblichkeit und einer postmortalen Fortexistenz beschäftigen bearbeitet und hinsichtlich der weiteren Fragestellung bezüglich der möglichen Umsetzung dieses Themas im Ethikunterricht analysiert. Im Fachdidaktischen Teil folgt dann die Verknüpfung des Fokusthemas Tod, Jenseits und postmortale Fortexistenz mit dem Lehrplan und dem praktischen Ethikunterricht. Dazu werden Anknüpfungspunkte herausgearbeitet und im Sinne eines Bausteinsystems Unterrichtssequenzen dargestellt.
description: The present work, entitled "Death of the Soul. A discussion of the concept of post-mortem survival by means of selected examples in ethics lessons" deals in the first part with an introduction to the concept of death and the different concepts of soul and its continued existence. Here, different approaches are presented and differentiated from each other. In a literature section, the thoughts of the chosen philosophers Leibniz and Feuerbach are dis-cussed. Texts and writings that deal with the topic of immortality and post-mortem surviv-al are processed and analyzed with regard to the further question of the possible imple-mentation of this topic in ethics lessons. In the didactic part, the focus topic of death, after-life and post-mortem survival is then linked to the curriculum and practical ethics lessons. For this purpose, points of contact are carved out and teaching sequences are presented in the sense of a building block system.

description: Khasi Mandarin fruit (Citrus reticulata Blanco) is one of the most important commercial fruit crops in the northeastern hill region of India. The fruit is unique in taste, aroma, and flavour, thus considered one of the best mandarins. The fruits have several uses, including in food industries, pharmaceutical industries, etc., with the stored house of bioactive compounds for health benefits. Given these, good orchard management practices are very essential for higher yield and quality production of Khasi mandarin fruits. This will indirectly improve the economics of the orchardist.
title: Zukunft von Friedhöfen

description: Die vorliegende Forschungsarbeit widmet sich der Untersuchung der Möglichkeit, urbane Friedhöfe in eine symbiotische Beziehung mit ihren umliegenden Gemeinden zu integrieren, ohne dabei die Anforderungen einer sich wandelnden Trauerkultur und finanzielle Restriktionen zu vernachlässigen. Die Analyse basiert auf zwei exemplarischen Fallstudien: dem evangelischen Friedhof Matzleinsdorf in Wien und dem St. Jacobi Friedhof in Berlin. In ihrer Essenz konzentriert sich die Forschungsfrage auf die folgende Thematik: "Wie lassen sich städtische Friedhöfe so konzipieren, dass sie nahtlos in das soziale Gewebe der Gemeinden eingebunden sind und gleichzeitig die Möglichkeit bieten, vielfältige Nutzungsmöglichkeiten in der Zukunft zu gewährleisten?" In einer Ära, in der sich Trauergewohnheiten transformieren, Traditionen evolvieren und die demografische Struktur urbaner Gebiete einem Wandel unterzogen ist, sehen sich Friedhöfe zahlreichen Herausforderungen gegenüber. Rückläufige Einnahmen und der Druck, Friedhofsareale für neue städtebauliche Entwicklungen zu nutzen, erfordern innovative Herangehensweisen. Experten*inneninterviews und Befragungen von Friedhofsbesucher*innen veranschaulichten eindrucksvoll, die Nutzung von Friedhöfen sich oft über die bloße Trauerbewältigung hinaus erstreckt und vielschichtige Bedürfnisse erfüllt. Die vorliegende Arbeit bietet Einblicke dar-über, wie Städte Friedhöfe als vielseitige Räume gestalten können, die den Anforderungen der Bevölkerung gerecht werden, ohne dabei ihren einzigartigen Charakter zu kompromittieren. Die gewonnenen Erkenntnisse unterstreichen die noch immer wichtige Rolle von Friedhöfen in städtischen Gemeinschaften und präsentieren einen möglichen Pfad, wie Stadtplanung bei einer Umgestaltung die Bedürfnisse der Lebenden und der Verstorbenen in einem harmonischen Gleichgewicht miteinander bringen kann.
description: This research examines how urban cemeteries can be transformed into multifunctional spaces that meet today's needs. The analysis is based on two exemplary case studies: the evangelischer Friedhof Matzleinsdorf in Vienna and the Neue St. Jacobi Friedhof in Berlin. At a time when mourning habits are changing, traditions are evolving, and the demographics of urban areas are shifting, cemeteries are facing numerous challenges. Declining revenues and pressure to use cemetery land for new urban development require innovative approaches. Interviews with experts and surveys of cemetery visitors revealed that the use of cemeteries often goes beyond mourning and fulfills complex needs. This study offers insights into how cities can design cemeteries as multi-purpose spaces that meet the needs of the population without losing their unique character. The findings underscore the still important role of cemeteries in urban communities and suggest a way in which redesign can balance the needs of different user groups.

description: In 1897 Ostwald formulated his step rule for formation of the most stable crystal state for a system with crystal polymorphism. The rule describes the irreversible way a system converts to the crystal with lowest free energy. But in fact the irreversible way a supercooled gas below the triple point temperature $T_{tr.p.}$ crystallizes via a liquid droplet is an example of Ostwald's step rule. The homogeneous nucleation in the supersaturated gas is not to a crystal, but to a liquid-like critical nucleus. We have for the first time performed constant energy (NVE) Molecular Dynamics (MD) of homogeneous nucleation without the use of a thermostat. The simulations of homogeneous nucleation in a Lennard-Jones system from supersaturated vapor at temperatures below $T_{tr.p.}$ reveals that the nucleation to a liquid-like critical nucleus is initiated by a small cold cluster [S. Toxvaerd, J. Chem. Phys. \textbf{143} 154705 (2015)]. The release of latent heat at the subsequent droplet growth increases the temperature in the liquid-like droplet, which for not deep supercooling and/or low supersaturation, can exceed $T_{tr.p.}$. The temperature of the liquid-like droplet increases less for a low supersaturation and remains below $T_{tr.p.}$, but without a crystallization of the droplet for long times. The dissipation of the latent heat into the surrounding gas is affected by a traditional MD thermostat, with the consequence that droplet growth is different for (NVE) MD and constant temperature (NVT) MD.

description: We present an analysis of the effect of feedback from O- and B-type stars with data from the integral field spectrograph MUSE mounted on the Very Large Telescope of pillar-like structures in the Carina Nebular Complex, one of the most massive star-forming regions in the Galaxy. For the observed pillars, we compute gas electron densities and temperatures maps, produce integrated line and velocity maps of the ionised gas, study the ionisation fronts at the pillar tips, analyse the properties of the single regions, and detect two ionised jets originating from two distinct pillar tips. For each pillar tip we determine the incident ionising photon flux $Q_\mathrm{0,pil}$ originating from the nearby massive O- and B-type stars and compute the mass-loss rate $\dot{M}$ of the pillar tips due to photo-evaporation caused by the incident ionising radiation. We combine the results of the Carina data set with archival MUSE data of a pillar in NGC 3603 and with previously published MUSE data of the Pillars of Creation in M16, and with a total of 10 analysed pillars, find tight correlations between the ionising photon flux and the electron density, the electron density and the distance from the ionising sources, and the ionising photon flux and the mass-loss rate. The combined MUSE data sets of pillars in regions with different physical conditions and stellar content therefore yield an empirical quantification of the feedback effects of ionising radiation. In agreement with models, we find that $\dot{M}\propto Q_\mathrm{0,pil}^{1/2}$.

description: We prove that the scattering equation formalism for Yang-Mills amplitudes can be used to make manifest the theory's color-kinematics duality. This is achieved through a concrete reduction algorithm which renders this duality manifest term-by-term. The reduction follows from the recently derived set of identities for amplitudes expressed in the scattering equation formalism that are analogous to monodromy relations in string theory. A byproduct of our algorithm is a generalization of the identities among gravity and Yang-Mills amplitudes.

The "forgotten" pseudomomenta and gauge changes in generalized Landau Level problems: spatially nonuniform magnetic and temporally varying electric fields

description: By perceiving gauge invariance as an analytical tool in order to get insight into the states of the "generalized Landau problem" (a charged quantum particle moving inside a magnetic, and possibly electric field), and motivated by an early article that correctly warns against a naive use of gauge transformation procedures in the usual Landau problem (i.e. with the magnetic field being static and uniform), we first show how to bypass the complications pointed out in that article by solving the problem in full generality through gauge transformation techniques in a more appropriate manner. Our solution provides in simple and closed analytical forms all Landau Level-wavefunctions without the need to specify a particular vector potential. This we do by proper handling of the so-called pseudomomentum K (or of a quantity that we term pseudoangular momentum Lz), a method that is crucially different from the old warning argument, but also from standard treatments in textbooks and in research literature (where the usual Landau wavefunctions are employed - labeled with canonical momenta quantum numbers). Most importantly, we go further by showing that a similar procedure can be followed in the more difficult case of spatially-nonuniform magnetic fields: in such case we define K and Lz as plausible generalizations of the previous ordinary case, namely as appropriate line integrals of the inhomogeneous magnetic field - our method providing closed analytical expressions for all stationary state wavefunctions.. (see paper) ... also provide explicit Berry's phase calculations and their connection to probability currents and ...issues in elementary Quantum Mechanics and Condensed Matter Physics. As an added feature, we also show how the possible presence of an additional electric field can be treated through a further generalization of pseudomomenta and their proper handling.

description: We identify all small groups of order up to 288 in the GAP Library for which the Zassenhaus conjecture on rational conjugacy of units of finite order in the integral group ring cannot be established by an existing method. The groups must first survive all theoretical sieves and all known restrictions on partial augmentations (the HeLP$^+$ method). Then two new computational methods for verifying the Zassenhaus conjecture are applied to the unresolved cases, which we call the quotient method and the partially central unit construction method. To the cases that remain we attempt an assortment of special arguments available for units of certain orders and the lattice method. In the end, the Zassenhaus conjecture is verified for all groups of order less than 144 and we give a list of all remaining cases among groups of orders 144 to 287.

Our method involves reducing the problem to an equation with a single field, finding an analytic solution and perturbing around it. The perturbations can be written in a semi-analytic form. We argue that our technique lacks convergence problems and demonstrate the speed of convergence on an example potential.

description: In recent years, amplified by the unjust murders of George Floyd, Breonna Taylor, and countless other Black lives, there has been a national push to better educate our citizens about race and racism. In response, there have also been attempts to limit these discussions, with some states passing bills that prohibit teachers from talking about racism, white supremacy, and Critical Race Theory. However, in order to help our students develop into empathetic and informed citizens, discussions of race and racism must occur in classrooms. Due to the flexibility of their subject and the focus on identity development, California high school English teachers are uniquely situated to highlight these discussions in their classrooms, yet many teachers do not feel prepared or comfortable to do so early in their careers. In order to better understand how teachers’ level of comfort with and approaches to these conversations change throughout their career, I conducted semi structured interviews with four California Bay Area high school English teachers, all of whom work at the same school and have been teaching for over a decade. My findings revealed most of the teachers felt uncomfortable having these discussions with their students at the beginning of their career, but they all viewed English teachers as having some level of responsibility to facilitate these discussions and struggled to engage different student beliefs. They all gained comfort with these discussions throughout their career and were able to adapt their approaches to these conversations accordingly by taking into account how they frame and model these conversations, learning from their mistakes, and establishing a strong classroom culture. Importantly, through working with colleagues who were equally open-minded and committed to this work and learning from their students, especially their Students of Color, they were able to gain comfort with their discomfort in these conversations by acknowledging that they have a great extent to learn from others’ lived experiences and commitment to this work.

description: We present the results of a cross-correlation search for gravitational waves from SNR 1987A using the second year of LIGO Science Run 5 data. The frequency band 75--450\,Hz is searched. No evidence of gravitational waves is found. A 90\% confidence upper limit of $h_0 \leq 3.8\times10^{-25}$ is placed on the gravitational wave strain at the most sensitive frequency near 150\,Hz. This corresponds to an ellipticity of $ε\leq 8.2\times10^{-4}$ and improves on previously published strain upper limits by a factor $\approx4$. We perform a comprehensive suite of validations of the search algorithm and identify several computational savings which marginally sacrifice sensitivity in order to streamline the parameter space being searched. We estimate detection thresholds and sensitivities through Monte-Carlo simulations.

description: Conventional microscope objective lenses are diffraction limited, which means that they cannot resolve features smaller than half the illumination wavelength. Under white light illumination, such resolution limit is about 250-300 nm for an ordinary microscope. In this paper, we demonstrate a new superlensing objective lens which has a resolution of about 100 nm, offering at least two times resolution improvement over conventional objectives in resolution. This is achieved by integrating a conventional microscope objective lens with a superlensing microsphere lens using a 3D printed lens adaptor. The new objective lens was used for label-free super-resolution imaging of 100 nm-sized engineering and biological samples, including a Blu-ray disc sample, semiconductor chip and adenoviruses. Our work creates a solid base for developing a commercially-viable superlens prototype, which has potential to transform the field of optical microscopy and imaging.

description: Crowdsourced Live Streaming (CLS), most notably Twitch.tv, has seen explosive growth in its popularity in the past few years. In such systems, any user can lively broadcast video content of interest to others, e.g., from a game player to many online viewers. To fulfill the demands from both massive and heterogeneous broadcasters and viewers, expensive server clusters have been deployed to provide video ingesting and transcoding services. Despite the existence of highly popular channels, a significant portion of the channels is indeed unpopular. Yet as our measurement shows, these broadcasters are consuming considerable system resources; in particular, 25% (resp. 30%) of bandwidth (resp. computation) resources are used by the broadcasters who do not have any viewers at all. In this paper, we closely examine the challenge of handling unpopular live-broadcasting channels in CLS systems and present a comprehensive solution for service partitioning on hybrid cloud. The trace-driven evaluation shows that our hybrid cloud-assisted design can smartly assign ingesting and transcoding tasks to the elastic cloud virtual machines, providing flexible system deployment cost-effectively.

description: Interstellar complex organic molecules (COMs) are commonly observed during star formation, and are proposed to form through radical chemistry in icy grain mantles. Reactions between ions and neutral molecules in ices may provide an alternative cold channel to complexity, as ion-neutral reactions are thought to have low or even no energy barriers. Here we present a study of a the kinetics and mechanisms of a potential ion-generating acid-base reaction between NH$_{3}$ and HCOOH to form the salt NH$_{4}^{+}$HCOO$^{-}$. We observe salt growth at temperatures as low as 15K, indicating that this reaction is feasible in cold environments. The kinetics of salt growth are best fit by a two-step model involving a slow "pre-reaction" step followed by a fast reaction step. The reaction energy barrier is determined to be 70 $\pm$ 30K with a pre-exponential factor 1.4 $\pm$ 0.4 x 10$^{-3}$ s$^{-1}$. The pre-reaction rate varies under different experimental conditions and likely represents a combination of diffusion and orientation of reactant molecules. For a diffusion-limited case, the pre-reaction barrier is 770 $\pm$ 110K with a pre-exponential factor of $\sim$7.6 x 10$^{-3}$ s$^{-1}$. Acid-base chemistry of common ice constituents is thus a potential cold pathway to generating ions in interstellar ices.

description: We study a moisture model for warm clouds that has been used by Klein and Majda as a basis for multiscale asymptotic expansions for deep convective phenomena. These moisture balance equations correspond to a bulk microphysics closure in the spirit of Kessler and of Grabowski and Smolarkiewicz, in which water is present in the gaseous state as water vapor and in the liquid phase as cloud water and rain water. It thereby contains closures for the phase changes condensation and evaporation, as well as the processes of autoconversion of cloud water into rainwater and the collection of cloud water by the falling rain droplets. Phase changes are associated with enormous amounts of latent heat and therefore provide a strong coupling to the thermodynamic equation. In this work we assume the velocity field to be given and prove rigorously the global existence and uniqueness of uniformly bounded solutions of the moisture model with viscosity, diffusion and heat conduction. To guarantee local well-posedness we first need to establish local existence results for linear parabolic equations, subject to the Robin boundary conditions on the cylindric type of domains under consideration. We then derive a priori estimates, for proving the maximum principle, using the Stampacchia method, as well as the iterative method by Alikakos to obtain uniform boundedness. The evaporation term is of power law type, with an exponent in general less or equal to one and therefore making the proof of uniqueness more challenging. However, these difficulties can be circumvented by introducing new unknowns, which satisfy the required cancellation and monotonicity properties in the source terms.

description: The recent UHECR events by AUGER and the Telescope Array (TA) suggested that wide clusterings as the North and South, named Hot Spot, are related to near AGNs such as the one in M82 and Cen A. In the same frame since 2008 we assumed that the UHECR are made by light and lightest nuclei to explain the otherwise embarrassing absence of the huge nearby Virgo cluster, absence due to the fragility and the opacity of lightest nuclei by photo-dissociation from Virgo distances. Moreover UHECR map exhibits a few narrow clustering, some near the galactic plane, as toward SS 433 and on the opposite side of the plane at celestial horizons: we tagged them in 2014 suggesting possible near source active also as a UHE neutrino. Indeed since last year, 2015, highest IceCube trough-going muons, UHE up-going neutrino events at hundreds TeV energy, did show (by two cases over three tagged in North sky) the expected overlapping of UHE neutrinos signals with narrow crowding UHECR. New data with higher energy threshold somehow re-confirmed our preliminary proposal; new possible sources appear by a additional correlated UHE-neutrino versus UHE-neutrino and-or with narrow UHECR clustering events. A possible role of relic neutrino mass scattering by ZeV neutrino arised.

description: This paper studies the resonant frequencies of three-string networks by examining the roots of the relevant spectral equation. A collection of scaling laws are established which relate the frequencies to structured changes in the lengths, densities, and tensions of the strings. Asymptotic properties of the system are derived, and several situations where transcritical bifurcations occur are detailed. Numerical optimization is used to solve the inverse problem (where a desired set of frequencies is specified and the parameters of the system are adjusted to best realize the specification). The intrinsic dissonance of the overtones provides an approximate way to measure the inherent inharmonicity of the sound.

description: The aim of this paper is to argue that complementation is an operation similarly fundamental to music theory as transposition and inversion. We focus on studying the chromatic complement mapping that translates diatonic seventh chords into 8-note scales which can also be interpreted as rhythmic beat patterns. Such complements of diatonic seventh chords are of particular importance since they correspond to the scales popularized by the Jazz theorist Barry Harris, as well as to rhythms used in African drum music and Steve Reich's Clapping Music. Our approach enables a systematic study of these scales and rhythms using established theories of efficient voice leading and generalized diatonic scales and chords, in particular the theory of second-order maximally even sets. The main contributions of this research are (1) to explicate the correspondence between voice leadings and rhythmic transformations, (2) to systematize the family of Barry Harris scales, and (3) to describe classes of voice leadings between chords of different cardinality that are invariant under complementation.

description: Observations of stellar streams in M31's outer halo suggest that M31 is actively accreting several dwarf galaxies and their globular clusters (GCs). Detailed abundances can chemically link clusters to their birth environments, establishing whether or not a GC has been accreted from a satellite dwarf galaxy. This talk presents the detailed chemical abundances of seven M31 outer halo GCs (with projected distances from M31 greater than 30 kpc), as derived from high-resolution integrated-light spectra taken with the Hobby Eberly Telescope. Five of these clusters were recently discovered in the Pan-Andromeda Archaeological Survey (PAndAS)---this talk presents the first determinations of integrated Fe, Na, Mg, Ca, Ti, Ni, Ba, and Eu abundances for these clusters. Four of the target clusters (PA06, PA53, PA54, and PA56) are metal-poor ($[\rm{Fe/H}] < -1.5$), $α$-enhanced (though they are possibly less alpha-enhanced than Milky Way stars at the 1 sigma level), and show signs of star-to-star Na and Mg variations. The other three GCs (H10, H23, and PA17) are more metal-rich, with metallicities ranging from [Fe/H] = -1.4 to -0.9. While H23 is chemically similar to Milky Way field stars, Milky Way GCs, and other M31 clusters, H10 and PA17 have moderately-low [Ca/Fe], compared to Milky Way field stars and clusters. Additionally, PA17's high [Mg/Ca] and [Ba/Eu] ratios are distinct from Milky Way stars, and are in better agreement with the stars and clusters in the Large Magellanic Cloud (LMC). None of the clusters studied here can be conclusively linked to any of the identified streams from PAndAS; however, based on their locations, kinematics, metallicities, and detailed abundances, the most metal-rich PAndAS clusters H23 and PA17 may be associated with the progenitor of the Giant Stellar Stream, H10 may be associated with the SW Cloud, and PA53 and PA56 may be associated with the Eastern Cloud.

Field Stabilization of Alvarez-Type Cavities

description: Alvarez-type cavities are commonly used to reliably accelerate high quality hadron beams. Optimization of their longitudinal field homogeneity is usually accomplished by post-couplers, i.e. additional rods being integrated into the cavity. This paper instead proposes to use the stems that keep the drift tubes for that purpose. As their individual azimuthal orientations do not change the cavity's undisturbed operational mode, they comprise a set of free parameters that can be used to modify higher mode field patterns. The latter have significant impact on the robustness of the operational mode w.r.t. eventual perturbations. Several optimized stem configurations are presented and benchmarked against each other. The path to obtain these configurations is paved analytically and worked out in detail through simulations. It is shown that the method provides for flat field distributions and very low field tilt sensitivities without insertion of post-couplers.

description: The study determined the dynamics of growing grain crops in Ukraine and the geography of their export. The problems of ensuring export logistics as a result of military aggression by russia in the context of ensuring food security are pointed out. The main directions of export logistics of grain crops from Ukraine and the peculiarities of transportation by railway, river and road transport were studied. The directions of diversification of export logistics of grain crops from Ukraine during martial law in the context of ensuring food security have been determined. Further ways of ensuring the development of the export of grain crops from Ukraine and improving the logistics infrastructure are substantiated. A description of the directions of cooperation between Ukraine and the European Union countries regarding the promotion and support of export logistics to the main countries of importers of agricultural products to ensure food security is provided. Ways of post-war restoration of the logistics of export of agricultural products from Ukraine and ensuring the sustainability of agricultural producers are considered.

description: In the present paper we continue our investigations of the representation theoretic side of reflection positivity by studying positive definite functions ψon the additive group (R,+) satisfying a suitably defined KMS condition. These functions take values in the space Bil(V) of bilinear forms on a real vector space V. As in quantum statistical mechanics, the KMS condition is defined in terms of an analytic continuation of ψto the strip { z \in C\: 0 \leq Im z \leq b} with a coupling condition ψ(ib + t) = \oline{ψ(t)} on the boundary. Our first main result consists of a characterization of these functions in terms of modular objects (Δ, J) (J an antilinear involution and Δ> 0 selfadjoint with JΔJ = Δ^{-1}) and an integral representation. Our second main result is the existence of a Bil(V)-valued positive definite function f on the group R_τ= R \rtimes {\id_\R,τ} with τ(t) = -t satisfying f(t,τ) = ψ(it) for t \in R. We thus obtain a 2b-periodic unitary one-parameter group on the GNS space H_f for which the one-parameter group on the GNS space H_ψis obtained by Osterwalder--Schrader quantization. Finally, we show that the building blocks of these representations arise from bundle-valued Sobolev spaces corresponding to the kernels 1/(λ^2 - (d^2)/(dt^2}) on the circle R/bZ of length b.
title: Humor in der politischen Kommunikation
Creators: name: Ruzicka, Manuela
Year: 2024

description: Diese Arbeit beschäftigt sich mit dem Einsatz von Humor in der politischen Kommunikation. Dafür werden qualitative Interviews geführt und ausgewertet. Politische Kommunikation wird dabei auf die Akteur*innen der Kommunikation von Parteien eingegrenzt, also den Kommunikationspraktiker*innen. Humor bleibt in seiner Definition breit gefasst, um den Interpretationsraum für die Interviewpartner*innen zu gewährleisten. Generell zeigt sich in der Arbeit, dass Humor in der politischen Kommunikation vor allem inhaltsanalytisch von außen oder auf der Wirkungsebene untersucht wird. Diese Arbeit beschäftigt sich deshalb mit der Perspektive der Kommunikationspraktiker*innen. Anhand von sechs Forschungsfragen werden sie über ihre Einschätzung zur Art und dem Zweck von Humor, den Einfluss von politischen und thematischen Kontexten und der Relevanz von Zielgruppen und Plattformen für die Entscheidung zum Einsatz von Humor in der politischen Kommunikation befragt. Je nach Forschungsfrage kommen unterschiedlich genaue und treffsichere Ergebnisse zum Vorschein. Insgesamt lässt sich zusammenfassen, dass aggressiver oder selbstabschätziger Humor verwendet wird, um Inhalte klar und prägnant als Oppositionspartei von jungen Politiker*innen an ein junges Publikum auf Social Media zu vermitteln.
description: This Masters Thesis is taking a closer look at humour in political communication. Therefore, qualitative interviews are conducted. The approach to political communication is defined by the actors of party communication, the communication practitioners. Humour will be defined in a broad way, to leave room for interpretation for the interviewees. Previous work shows, that humour in political communication is oftentimes researched via content analysis or impact research, both from the outside perspective. This thesis is looking at it through the perspective of the communication practitioners themselves. The research is led by six research questions, dealing with the kind of humour and the purpose of the use of humour, the impact of political and thematical contexts and the relevance of target groups and platforms on the decision of the use of humour in political communication. The results vary between the research questions and are different in their accuracy. Altogether the conclusion is, that aggressive and selfdeprecating humour is being used to convey clear messages from opposition parties through young politicians to a young audience via Social Media.
Galois groups for integrable and projectively integrable linear difference equations

description: We consider first-order linear difference systems over $\mathbb{C}(x)$, with respect to a difference operator $σ$ that is either a shift $σ:x\mapsto x+1$, $q$-dilation $σ:x\mapsto qx$ with $q\in{\mathbb{C}^\times}$ not a root of unity, or Mahler operator $σ:x\mapsto x^q$ with $q\in\mathbb{Z}_{\geq 2}$. Such a system is integrable if its solutions also satisfy a linear differential system; it is projectively integrable if it becomes integrable "after moding out by scalars." We apply recent results of Schäfke and Singer to characterize which groups can occur as Galois groups of integrable or projectively integrable linear difference systems. In particular, such groups must be solvable. Finally, we give hypertranscendence criteria.
