description: Several COVID-19 studies on the felt passage of time have been conducted due to the strong feeling of time distortion many people have experienced during the pandemic. Overall, a relative decelaration of time passage was generally associated with negative affect and social isolation; a relative acceleration was associated with an increase in routine in daily life. There is some variability in results depending on the country of study and COVID-19 restrictions introduced, participants’ demographics, and questionnaire items applied. Here we present a study conducted in May 2021 in Germany including n = 500 participants to assess time perception, emotional reactions, and attitudes towards the countermeasures. The passage of time judgments (POTJ) for the preceding 12 months during the pandemic were compared to data addressing the same question posed in previous studies conducted before the outbreak of COVID-19. The previous year was rated as having passed relatively slower during the pandemic compared to the ratings from before the pandemic. The duration judgments (DJ) of the 14 months since the start of the pandemic showed a bimodal distribution with both relatively shorter and relatively longer DJs. Higher levels of several negative emotions, as well as less social satisfaction, were associated with prolonged DJs and partially slower POTJs. Fear for health was not linked with the subjective experience of time, but exploratory analyses suggested that higher levels of fear were linked to more positive evaluations and approval of the governmental countermeasures. Those who reported higher levels of negative, agitated-aggressive emotions showed lower levels of consent with these measures.

description: We study thermoelectric transport at low temperatures in correlated Kondo insulators, motivated by the recent observation of a high thermoelectric figure of merit(ZT) in $FeSb_2$ at $T \sim 10 K$. Even at room temperature, correlations have the potential to lead to high ZT, as in $YbAl_3$, one of the most widely used thermoelectric metals. At low temperature correlation effects are especially worthy of study because fixed band structures are unlikely to give rise to the very small energy gaps $E_g \sim 5 kT$ necessary for a weakly correlated material to function efficiently at low temperature. We explore the possibility of improving the thermoelectric properties of correlated Kondo insulators through tuning of crystal field and spin-orbit coupling and present a framework to design more efficient low-temperature thermoelectrics based on our results.

description: We present two complementary strategies for modeling nonlinear quantum optics in realistic integrated optical devices, where scattering loss is present. In the first strategy, we model scattering loss as an attenuation; in the second, we employ a Hamiltonian treatment that includes a mechanism for scattering loss, such as a `phantom waveguide.' These strategies can be applied to a broad range of structures and processes. As an example, we use these two approaches to model spontaneous four-wave mixing in (i) a ring-channel system and (ii) an add-drop system. Even for these well-understood systems, our strategies yield some novel results. We show the rates of photon pairs, broken pairs, and lost pairs and their dependence on system parameters. We show that the properties of lost and broken photon pairs in such structures can be related to those of the un-scattered photon pairs, which are relatively simple to measure.

Furthermore, the interplay between dissipative and conservative solutions is treated.

description: We show how for $n=2,3 (\mod 4)$ continuous Clifford (geometric) algebra (GA) $Cl_n$-valued admissible wavelets can be constructed using the similitude group $SIM(n)$. We strictly aim for real geometric interpretation, and replace the imaginary unit $i \in \C$ therefore with a GA blade squaring to $-1$. Consequences due to non-commutativity arise. We express the admissibility condition in terms of a $Cl_{n}$ Clifford Fourier Transform and then derive a set of important properties such as dilation, translation and rotation covariance, a reproducing kernel, and show how to invert the Clifford wavelet transform. As an example, we introduce Clifford Gabor wavelets. We further invent a generalized Clifford wavelet uncertainty principle.

Some brief qualitative letter-comments  on quantizing gravity: thirteen hypotheses

description: Abstract:
 
Since the 1930's, when at first Goldstein tried to quantize the gravity-field of a light-beam and failed because he got infinities in his solution, the problem of non-renomalization in quantizing gravity occured. In the mean time till today many intelligent tryings are made to quantize gravity in a successful way. Some Supergravity-theories failed also. The most promising tryings nowadays are superstringtheories and loop-gravity but with some strange results. So here are some qualitative thoughts about quantizing gravity. There are then thirteen possibilities (may be more) respectively thirteen commandements.
HampDTI: a heterogeneous graph automatic meta-path learning method for drug-target interaction prediction

description: Motivation: Identifying drug-target interactions (DTIs) is a key step in drug repositioning. In recent years, the accumulation of a large number of genomics and pharmacology data has formed mass drug and target related heterogeneous networks (HNs), which provides new opportunities of developing HN-based computational models to accurately predict DTIs. The HN implies lots of useful information about DTIs but also contains irrelevant data, and how to make the best of heterogeneous networks remains a challenge. Results: In this paper, we propose a heterogeneous graph automatic meta-path learning based DTI prediction method (HampDTI). HampDTI automatically learns the important meta-paths between drugs and targets from the HN, and generates meta-path graphs. For each meta-path graph, the features learned from drug molecule graphs and target protein sequences serve as the node attributes, and then a node-type specific graph convolutional network (NSGCN) which efficiently considers node type information (drugs or targets) is designed to learn embeddings of drugs and targets. Finally, the embeddings from multiple meta-path graphs are combined to predict novel DTIs. The experiments on benchmark datasets show that our proposed HampDTI achieves superior performance compared with state-of-the-art DTI prediction methods. More importantly, HampDTI identifies the important meta-paths for DTI prediction, which could explain how drugs connect with targets in HNs.

Fast computation of the Lorentz force induced by longitudinal electromagnetic stirring

description: In this work, we revisit a recent transient three-dimensional (3D) model for longitudinal electromagnetic stirring in the continuous casting of rectangular steel blooms. Whereas the earlier work was able to demonstrate accurate approximations to the solutions in two asymptotic limits, both of which gave economical alternatives to time-consuming 3D computations, here we show that the original governing equations can be manipulated to a form that allows for rapid computation even outside of these asymptotic limits. The resulting formulation requires the numerical solution of two steady-state complex Helmholtz-like equations in two dimensions that are coupled via a non-standard internal interface condition that is reminiscent of that occurring in the study of Marangoni convection; these equations are then solved numerically using the finite-element software Comsol Multiphysics. With this formulation, it is possible to compute the time-averaged Lorentz force components in a way that requires around four orders of magnitude less computational time than the fully 3D approach

description: In the standard model of cosmology, structure emerges out of non-rotational flow and the angular momentum of collapsing halos is induced by tidal torques. The growth of halo angular momentum in the linear and quasi-linear phases is associated with a shear, curl-free, flow and it is well described within the linear framework of tidal torque theory (TTT). However, TTT is rendered irrelevant as haloes approach turn around and virialization. At that stage the flow field around halos has non-zero vorticity. Using a cosmological simulation, we have examined the importance of the curl of the velocity field (vorticity) in determining halo spin, finding a strong alignment between the two. We have also examined the alignment of vorticity with the principle axes of the shear tensor, finding that it tends to be perpendicular to the axis along which material is collapsing fastest (e1). This behavior is independent of halo masses and cosmic web environment. Our results agree with previous findings on the tendency of halo spin to be perpendicular to e1, and of the spin of (simulated) halos and (observed) galaxies to be aligned with the large-scale structure. Our results imply that angular momentum growth proceeds in two distinct phases. In the first phase angular momentum emerges out of a shear, curl-free, potential flow, as described by TTT. In the second phase, in which haloes approach virialization, the angular momentum emerges out of a vortical flow and halo spin becomes strongly aligned with the vorticity of the ambient flow field.

description: Financial inclusion depends on providing adjusted services for citizens with disclosed vulnerabilities. At the same time, the financial industry needs to adhere to a strict regulatory framework, which is often in conflict with the desire for inclusive, adaptive, and privacy-preserving services. In this article we study how this tension impacts the deployment of privacy-sensitive technologies aimed at financial inclusion. We conduct a qualitative study with banking experts to understand their perspectives on service development for financial inclusion. We build and demonstrate a prototype solution based on open source decentralized identifiers and verifiable credentials software and report on feedback from the banking experts on this system. The technology is promising thanks to its selective disclosure of vulnerabilities to the full control of the individual. This supports GDPR requirements, but at the same time, there is a clear tension between introducing these technologies and fulfilling other regulatory requirements, particularly with respect to 'Know Your Customer.' We consider the policy implications stemming from these tensions and provide guidelines for the further design of related technologies.

description: BackgroundHospital-acquired infections (HAIs) and infectious agents exhibiting antimicrobial resistance (AMR) are challenges globally. Environmental patient-facing wastewater apparatus including handwashing sinks, showers and toilets are increasingly identified as sources of infectious agents and AMR genes.AimTo provide large-scale metagenomics analysis of wastewater systems in a large teaching hospital in the Republic of Ireland experiencing multi-drug-resistant HAI outbreaks.MethodsWastewater pipe sections (N=20) were removed immediately prior to refurbishment of a medical ward where HAIs had been endemic. These comprised toilet U-bends, and sink and shower drains. Following DNA extraction, each pipe section underwent metagenomic analysis.FindingsDiverse taxonomic and resistome profiles were observed, with members of phyla Proteobacteria and Actinobacteria dominating (38.23 ± 5.68% and 15.78 ± 3.53%, respectively). Genomes of five clinical isolates were analysed. These AMR bacterial isolates were from patients >48 h post-admission to the ward. Genomic analysis determined that the isolates bore a high number of antimicrobial resistance genes (ARGs).ConclusionComparison of resistome profiles of isolates and wastewater metagenomes revealed high degrees of similarity, with many identical ARGs shared, suggesting probable acquisition post-admission. The highest numbers of ARGs observed were those encoding resistance to clinically significant and commonly used antibiotic classes. Average nucleotide identity analysis confirmed the presence of highly similar or identical genomes in clinical isolates and wastewater pipes. These unique large-scale analyses reinforce the need for regular cleaning and decontamination of patient-facing hospital wastewater pipes and effective infection control policies to prevent transmission of nosocomial infection and emergence of AMR within potential wastewater reservoirs.

description: We seek to connect ideas in the theory of bridge trisections with other well-studied facets of classical knotted surface theory.

Second, we describe in detail how to compute the fundamental group and related invariants from a tri-plane diagram, and we use this, together with an analysis of bridge trisections of ribbon surfaces, to produce an infinite family of knotted spheres that admit non-isotopic bridge trisections of minimal complexity.

If $M^{2n}$ if simply connected, this amounts to the existence of a one-parameter associated family of isometric minimal immersions unless $f$ is holomorphic.

description: We extend the existing analytical model of reionization by Furlanetto et al. (2004) to include the biasing of reionization sources and additional absorption by Lyman Limit systems. Our model is, by construction, consistent with the observed evolution of the galaxy luminosity function at z<8 and with the observed evolution of Ly-α forest at z<6. We also find that, for a wide range of values for the relative escape fraction that we consider reasonable, and which are consistent with the observational constraints on the relative escape fraction from lower redshifts, our reionization model is consistent with the WMAP constraint on the Thompson optical depth and with the SPT and EDGES constraints on the duration of reionization. We, therefore, conclude that it is possible to develop physically realistic models of reionization that are consistent with all existing observational constraints.

description: Non-Hermiticity significantly enriches the properties of topological models, leading to exotic features such as the non-Hermitian skin effects and non-Bloch bulk-boundary correspondence that have no counterparts in Hermitian settings. Its impact is particularly illustrating in non-Hermitian quasicrystals where the interplay between non-Hermiticity and quasiperiodicity results in the concurrence of the delocalization-localization transition, the parity-time (PT)-symmetry breaking, and the onset of the non-Hermitian skin effects. Here we experimentally simulate non-Hermitian quasicrystals using photonic quantum walks. Using dynamic observables, we demonstrate that the system can transit from a delocalized, PT-symmetry broken phase that features non-Hermitian skin effects, to a localized, PT-symmetry unbroken phase with no non-Hermitian skin effects. The measured critical point is consistent with the theoretical prediction through a spectral winding number, confirming the topological origin of the phase transition. Our work opens the avenue of investigating the interplay of non-Hermiticity, quasiperiodicity, and spectral topology in open quantum systems.

description: Directional data arise in various contexts such as oceanography (wave directions) and meteorology (wind directions), as well as with measurements on a periodic scale (weekdays, hours, etc.). Our contribution is to introduce a model-based approach to handle periodic data in the case of measurements taken at spatial locations, anticipating structured dependence between these measurements. We formulate a wrapped Gaussian spatial process model for this setting, induced from a customary linear Gaussian process. We build a hierarchical model to handle this situation and show that the fitting of such a model is possible using standard Markov chain Monte Carlo methods. Our approach enables spatial interpolation (and can accommodate measurement error). We illustrate with a set of wave direction data from the Adriatic coast of Italy, generated through a complex computer model.

description: A general geometric construction of a generic null hypersurface in presence of torsion in the spacetime (Riemann-Cartan background), generated by a null vector $l^a$, is being developed here. We then explicitly define and structure various corresponding kinematical quantities. The dynamics of the null surface, particularly given by $\hat{G}_{ab}k^al^b$, is also discussed. The later one is constructed under the {\it geodesic constraint} condition. This yields a relation among the rate of change of expansion scalar corresponding to auxiliary null vector $k^a$ and various kinematical entities on the null surface. Using this relation we show that the Einstein-Cartan-Kibble-Sciama equation (which provides the dynamics of the metric and the torsion tensor) on this null hypersurface acquires a thermodynamic interpretation. The thermodynamic entities like temperature, entropy density, energy and pressure are properly identified. In the whole analysis we adopt the geometrical field interpretation of torsion and all discussions are done in a covariant manner.

description: Dynamic motions are a key feature of robotic arms, enabling them to perform tasks quickly and efficiently. Soft continuum manipulators do not currently consider dynamic parameters when operating in task space. This shortcoming makes existing soft robots slow and limits their ability to deal with external forces, especially during object manipulation. We address this issue by using dynamic operational space control. Our control approach takes into account the dynamic parameters of the 3D continuum arm and introduces new models that enable multi-segment soft manipulators to operate smoothly in task space. Advanced control methods, previously afforded only to rigid robots, are now adapted to soft robots; for example, potential field avoidance was previously only shown for rigid robots and is now extended to soft robots. Using our approach, a soft manipulator can now achieve a variety of tasks that were previously not possible: we evaluate the manipulator's performance in closed-loop controlled experiments such as pick-and-place, obstacle avoidance, throwing objects using an attached soft gripper, and deliberately applying forces to a surface by drawing with a grasped piece of chalk. Besides the newly enabled skills, our approach improves tracking accuracy by 59% and increases speed by a factor of 19.3 compared to state of the art for task space control. With these newfound abilities, soft robots can start to challenge rigid robots in the field of manipulation. Our inherently safe and compliant soft robot moves the future of robotic manipulation towards a cageless setup where humans and robots work in parallel.

description: Die Lehrerbildungsforschung steht immer wieder vor der Herausforderung der unterschiedlichen Kontexte und Gestaltungen der Praktika, in denen empirische Untersuchen stattfinden. Die Heterogenität der Ausbildungen wird beeinflusst durch die jeweiligen Institutionskulturen, welche bei der Interpretation von Forschungsergebnissen berücksichtigt werden müssen. Anhand einer Dokumentenanalyse und Ratingkonferenzen wird in diesem Beitrag versucht, eine Möglichkeit der Identifikation von Praktikumskulturen darzustellen. Die Analyse der Dokumente und das Zusammenführen mit den Ratingkonferenzen ermöglicht eine Rekonstruktion der Praktikumskulturen im Dialog mit den beteiligten Akteuren. In die Untersuchung miteinbezogen wurden an Standort X zehn Dokumente und drei Ratingkonferenzen mit insgesamt fünf Studierenden, sechs Praxislehrpersonen und sechs Dozierenden. Im Bereich „Mitbestimmung der Studierenden“ zeigten sich Kontroversen um die Verwirklichung gesetzter Ziele. Vorgaben durch die Hochschule als Bildungsinstitution bzgl. der Mitbestimmung der Studierenden bilden sich in den Gruppendiskussionen als nicht umgesetzt ab. Bezogen auf den Ansatz der Rekontextualisierung nach Fend (2006) konnte der Beitrag zeigen, wie institutionelle Vorgaben aus den Dokumenten in der Praxis durch die Akteure individuell ausgestaltet wurden und welches Verständnis des Begriffs „Mitbestimmung“ bei Praxislehrperson und Studierenden vorliegt.

description: Biological locomotion, observed in the flexible wings of birds and insects, bodies and fins of aquatic mammals and fishes, consists of their ability to morph the wings/fins. The morphing capability holds significance in the abilities of fishes to swim upstream without spending too much energy and that of birds to glide for extended periods of time. Simplifying the wing or fins to a foil, morphing refers to the ability of the foil to change its camber smoothly, without sharp bends on the foil surface. This allows precise control over flow separation and vortex shedding. Compared to conventional trailing-edge extensions or flaps, used in rudders and elevators in submarines and ships, morphing foils provide better control of thrust and lift characteristics. This study aims at understanding the importance of the morphing of foil combined with a sinusoidal heaving motion on thrust generation. A two-dimensional variational stabilized Petrov-Galerkin moving mesh framework is utilized for modelling the incompressible low Reynolds number flow across the flapping foil. The morphing motion is characterized by the extent of morphing, measured as an angle of deviation from the initial camber, and the point of initiation of morphing on the foil as a percentage of its chord length. The effect of the foil morphing and the heaving motion on the propulsive performance are investigated. The extent of morphing is varied from -30 deg and 30 deg, and the point of initiation ranges from 15% to 50% of the chord. The Reynolds and Strouhal numbers for the study are 1100 and 0.2, respectively. The results from the current work can pave the way for enhanced engineering designs in bio-mimetics and give insights on design conditions for optimal thrust performance.

Mathematical structure of unit systems
Creators: name: Kitano, Masao
Publisher: name: arXiv
Year: 2013
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: We investigate the mathematical structure of unit systems and the relations between them. Looking over the entire set of unit systems, we can find a mathematical structure that is called preorder (or quasi-order). For some pair of unit systems, there exists a relation of preorder such that one unit system is transferable to the other unit system. The transfer (or conversion) is possible only when all of the quantities distinguishable in the latter system are always distinguishable in the former system. By utilizing this structure, we can systematically compare the representations in different unit systems. Especially, the equivalence class of unit systems (EUS) plays an important role because the representations of physical quantities and equations are of the same form in unit systems belonging to an EUS. The dimension of quantities is uniquely defined in each EUS. The EUS's form a partially ordered set. Using these mathematical structures, unit systems and EUS's are systematically classified and organized as a hierarchical tree.

title: Scampoli di ricerche critiche su Petrarca e la sua fortuna
Creators: name: Cherchi, Paolo
Publisher: name: UNICApress
Year: 2023

description: Gli “scampoli” raccolti in questo volume sono piuttosto dei “frammenti” intesi nell’accezione petrarchesca, come scaglie di un complesso organico, come attimi che danno la percezione di cosa sia il tempo. Petrarca è un autore accessibile perché piano ed elegante, ma in realtà è dottissimo senza farne ostentazione, per cui sorprende ogni volta che si scopre una trama di allusioni letterarie dietro a dati presentati in modo dimesso. Ogni “scampolo” è la testimonianza di queste occasionali scoperte, di letture che non cercano il “soprasenso” allegorico, ma il sottofondo erudito di questa scrittura. Una sezione iniziale indica nella “vita solitaria” la matrice di questa familiarità e intimità con i testi antichi. Un’altra sezione e più estesa individua “fonti” specifiche su punti dove non se ne sospetterebbe la presenza. Un altro gruppo riguarda la fortuna di Petrarca, ossia le diverse letture della sua opera date in ambienti e in epoche diverse. Infine un saggio sul mondo “privato” dell’autore che combatte contro le superstizioni ma non si sente del tutto affrancato da queste. Quindi non un libro “organico” nel senso tradizionale, e tuttavia un lavoro unitario in quanto dedicato alla ricostruzione di uno stile di lavoro e ai vari modi di fruirlo.
Clifford (Geometric) Algebra Wavelet Transform

description: While the Clifford (geometric) algebra Fourier Transform (CFT) is global, we introduce here the local Clifford (geometric) algebra (GA) wavelet concept. We show how for $n=2,3 (\mod 4)$ continuous $Cl_n$-valued admissible wavelets can be constructed using the similitude group $SIM(n)$. We strictly aim for real geometric interpretation, and replace the imaginary unit $i \in \C$ therefore with a GA blade squaring to $-1$. Consequences due to non-commutativity arise. We express the admissibility condition in terms of a $Cl_{n}$ CFT and then derive a set of important properties such as dilation, translation and rotation covariance, a reproducing kernel, and show how to invert the Clifford wavelet transform. As an explicit example, we introduce Clifford Gabor wavelets. We further invent a generalized Clifford wavelet uncertainty principle. Extensions of CFTs and Clifford wavelets to $Cl_{0,n'}, n' = 1,2 (\mod 4)$ appear straight forward. Keywords: Clifford geometric algebra, Clifford wavelet transform, multidimensional wavelets, continuous wavelets, similitude group.

description: We report on a search for low mass companions within 10 AU of the star Fomalhaut, using narrow band observations at 4.05 microns obtained with the Apodizing Phase Plate (APP) coronagraph on the VLT/NaCo. Our observations place a model dependent upper mass limit of 12-20 Jupiter masses from 4 to 10 AU, covering the semi-major axis search space between interferometric imaging measurements and other direct imaging non-detections. These observations rule out models where the large semi-major axis for the putative candidate companion Fomalhaut b is explained by dynamical scattering from a more massive companion in the inner stellar system, where such giant planets are thought to form.

description: We model spontaneous parametric down-conversion (SPDC) as classical difference frequency generation (DFG) of the pump field and a hypothetical stochastic "vacuum" seed field. We analytically show that the second-order spatiotemporal correlations of the field generated from the DFG process replicate those of the signal field from SPDC. Specifically, for low gain, the model is consistent with the quantum calculation of the signal photon's reduced density matrix; and for high gain, the model's predictions are in good agreement with our experimental measurements of the far-field intensity profile, orbital angular momentum spectrum, and wavelength spectrum of the SPDC field for increasing pump strengths. We further theoretically show that the model successfully captures second-order SU(1,1) interference and induced coherence effects in both gain regimes. Intriguingly, the model also correctly predicts the linear scaling of the interference visibility with object transmittance in the low-gain regime -- a feature that is often regarded as a quintessential signature of the nonclassicality of induced coherence. Our model may not only lead to novel fundamental insights into the classical-quantum divide in the context of SPDC and induced coherence, but can also be a useful theoretical tool for numerous experiments and applications based on SPDC.

Subjects: subject: 330 - Wirtschaft

description: Diese Bachelorarbeit untersucht die strategische Nutzung von TikTok im Hinblick auf die zukünftige Inhaltspräsentation der Hochschule für Angewandte Psychologie (APS). Ziel ist es, herauszufinden, welche Inhalte von der APS präsentiert werden sollten, um die Bekanntheit der Institution zu steigern. Die Literaturrecherche zeigte, eine Lücke in Bezug auf den zu präsentierenden Inhalt, wodurch sich die Frage ergibt, welche Themen die APS in ihrer Inhaltsdarbietung behandeln sollte. Um diese Frage zu klären, wurden mittels einer deskriptiven Inhaltsanalyse zunächst 150 erfolgreiche Videos auf der Plattform TikTok analysiert und daraus acht potenzielle Themenkategorien ermittelt. Auf Basis dieser wurde eine Onlineumfrage mit 213 Teilnehmenden durchgeführt, in welcher diese acht Themenkategorien nach ihrer Erwünschtheit gemässen wurden. Die Resultate aus den beiden Erhebungen zeigen, dass mittels allen acht Themenkategorien; „Nach dem Studium", „Anwendung der Psychologie", „Psychische Erkrankungen", „Persönlichkeit", „Allgemeine Tipps und Tricks", „Alles über das Studium", „Informationen über Schulen" und „Alltag eines Studierenden“ sowohl das Ziel nach Bekanntheit sowie die Erwartungen der Nutzenden erfühlt werden können. Weiter zeigte sich aus den Erhebungen, dass die dargebotenen Inhalte informativ, evidenzbasiert und prägnant sein sollten und auf eine ansprechende Art und Weise präsentiert werden müssen, um die Wahrscheinlichkeit, erfolgreich auf der Plattform zu performen, zu erhöhen.
The yield ratio of anti-nuclei and nuclei of relativistic nuclear collisions in the central rapidity region

description: This article describes calculations of the yield ratio of anti-particles to the yield of particles ($\bar{p}/p$, $\bar{d}/d$,$\overline{^{3}\mathrm{He}}$/$^{3}$He) in proton-proton and nuclear-nuclear interactions using the self-similarity parameter in the central rapidity region. The used approach is based on the study of relativistic nuclear interactions in the four-velocity space. The results of the calculations are compared with the existing experimental data in a wide center-of-mass energy range ($SPS$, $RHIC$, $LHC$). Within this approach the inclusive spectra of pions and kaons and ratios of their yields in $pp$ collisions have been successfully described earlier.
Anwendung von VertrauensArchitektur auf die Nachhaltigkeitskommunikation von Versicherungsgesellschaften, um Vertrauen zu stärken und wahrgenommenes Greenwashing zu reduzieren

description: In dieser Bachelorarbeit wurde erforscht, wie Vertrauen und wahrgenommenes Greenwashing durch die Vertrauensdeterminanten Integrität, Interessen, Fähigkeit, und Klarheit aus dem Vertrauensmodell nach Eller (2022) beeinflusst werden können, spezifisch in der Nachhaltigkeitskommunikation von Versicherungsgesellschaften auf ihrer Unternehmenswebseite. Die untersuchte Fragestellung lautete: Inwiefern kann VertrauensArchitektur Versicherungsgesellschaften helfen, Nachhaltigkeitskommunikation auf ihrer Webseite so zu gestalten, dass das Vertrauen von Kund*innen gefördert und wahrgenommenes Greenwashing verringert wird? Die Erhebung erfolgte als Online-Experiment in Form einer Online-Umfrage. Für das Experiment wurden, basierend auf den Erkenntnissen aus dem Literaturteil, synthetische Webseitenausschnitte kreiert, bei denen eine der Vertrauensdeterminanten jeweils entweder positiv ausgeprägt war oder gezielt vernachlässigt wurde. Die Wahrnehmung von drei der vier getesteten Vertrauensdeterminanten, namentlich Integrität, Fähigkeit, und Klarheit, konnte mithilfe der Webseitenausschnitte signifikant verbessert werden. Ausserdem konnte gezeigt werden, dass das entgegengebrachte explizite Vertrauen, wie auch die Wahrnehmung von Greenwashing mittel bis stark mit der Wahrnehmung der Vertrauensdeterminanten korreliert. Zudem konnte nachgewiesen werden, dass wahrgenommenes Greenwashing und Vertrauen höchst signifikant negativ miteinander korrelieren. Die Vertrauensdeterminante Fähigkeit wurde für das entgegengebrachte explizite Vertrauen wie auch die Wahrnehmung von Greenwashing aus der schrittweisen multiplen Regression als stärkster Faktor identifiziert und sollte deshalb in der Nachhaltigkeitskommunikation aktiv umgesetzt werden, indem Kompetenzen klar erkenntlich auf der Website kommuniziert werden.
