In this work, we aim to bridge this gap by studying the task of belief-based claim generation: Given a controversial topic and a set of beliefs, generate an argumentative claim tailored to the beliefs. To tackle this task, we model the people's prior beliefs through their stances on controversial topics and extend state-of-the-art text generation models to generate claims conditioned on the beliefs. Our automatic evaluation confirms the ability of our approach to adapt claims to a set of given beliefs. In a manual study, we additionally evaluate the generated claims in terms of informativeness and their likelihood to be uttered by someone with a respective belief.

Notably, these studies have in many cases resulted in different estimates of capacity limits than those found in studies using traditional TVA-based assessment.

We show that TVA can be used with other tasks and new stimuli, that TVA-based parameter estimation can be embedded into complex scenarios, such as games that can be used to investigate particular problems regarding visual attention, and how TVA-based simulations of “visual foraging” can elucidate attentional control in more naturalistic tasks.

Our results show that on average, first-generation immigrants have fewer years of schooling than native-born Germans and have a disproportionate share of lower educational qualifications. This gap is strongly driven by age at immigration, with immigration age and education revealing a nonlinear relationship. While the gap is relatively small among individuals who migrate at a young age, integrating in the school system at secondary school age leads to large disadvantages. Examining the educational mobility of immigrants in Germany, we identify an inter-generational catch-up in education. The gap in education between immigrants and natives is reduced for the second generation. Finally, we find that country of origin differences can account for much of the education gap.

To increase the sensitivity to these shear motions, arbitrary excitations were investigated by means of numerical simulation.

Since there is no generally accepted damping model for piezoelectric ceramics, several mechanical damping models are examined for the material identification. Three models have been chosen and their ability to replicate the measured impedances is evaluated. On the one hand, the common Rayleigh model is considered as a reference. On the other hand, a Zener model and a model using complex constants are extended to model the transversely isotropic material. As the Rayleigh model is only valid for a limited frequency range, it fails to model the broadband behaviour of the material. The model using complex constants leads to the best fit over a wide frequency range while at the same time only adding three additional parameters for modelling damping.

Modular SSTs which can be interpreted as modular multilevel converters with an isolated DC-DC output stage per module, are designed with redundant modules to increase reliability. Usually, each of the three arms operates independently, and therefore, only a fixed number of faulty modules can be compensated in each arm, even if all modules are operational in the remaining two arms. With the proposed zero-sequence voltage injection, up to 100% more faulty modules can be compensated in an arm by employing the same hardware. In addition, module power imbalances are nearly eliminated by utilizing a fundamental frequency zero-sequence voltage. A dominant 3rd harmonic zero-sequence voltage injection in combination with the 5th, 7th and several higher order harmonics with adaptive (small) amplitudes minimize the required arm voltages at steady-state.

These B cell frequencies correlated positively with fat mass, fat mass index (FMI), free fat mass index, and body mass index standard deviation score. In addition, scavenger-like receptor CD5 expression levels were downregulated on transitional B cells and correlated with fat mass and FMI in AN. Our findings that regulatory B cell subgroups were reduced in AN and their strong relationship with body composition parameters point toward an impact of immunoregulatory B cells in the pathogenesis of AN.}}, author = {{Freff, Jana and Schwarte, Kathrin and Bröker, Lisa and Bühlmeier, Judith and Kraft, Isabelle and Öztürk, Dana and Hinney, Anke and Arolt, Volker and Dannlowski, Udo and Romer, Georg and Baune, Bernhard T. and Hebebrand, Johannes and Föcker, Manuel and Alferink, Judith}}, issn = {{2045-2322}}, journal = {{Scientific Reports}}, title = {{{Alterations in B cell subsets correlate with body composition parameters in female adolescents with anorexia nervosa}}}, doi = {{10.1038/s41598-020-80693-4}}, year = {{2021}}, } @article{26525, author = {{Hebebrand, Johannes and Antel, Jochen and Tan, Susanne and Wabitsch, Martin and Wiesing, Urban and Barth, Nikolaus and Ludwig, Christine and Bühlmeier, Judith and Libuda, Lars and Milos, Gabriella and Hinney, Anke}}, issn = {{1422-4917}}, journal = {{Zeitschrift für Kinder- und Jugendpsychiatrie und Psychotherapie}}, pages = {{1--5}}, title = {{{Kurzzeitige Behandlung von Patient_innen mit Anorexia nervosa mit rekombinant hergestelltem Human-Leptin (Metreleptin): Rasch einsetzende positive Effekte auf Stimmung, Kognition und Verhalten}}}, doi = {{10.1024/1422-4917/a000775}}, year = {{2021}}, } @article{33410, author = {{Kißling, Magdalena}}, journal = {{Der Deutschunterrich (2) }}, pages = {{89--94}}, title = {{{Vom ‚Komaglotzen‘ zum literar- und medienästhetischen Lernen.
