description: In the history of civil engineering, the structures were usually designed considering only static load factor. Later due to research in the civil engineering field, it was explored that the structures are also acted upon by several other loads which included seismic loads, wind loads, snow loads and many others depending upon the dimensions of the structure, location of the structure, type of the ground profile, etc. Hence this brought in the process of analyzing a structure for different types of loads and designing the structure for the critical load case of which dynamic load is considered as one of the important load for which the structure should be analyzed and designed. The main aim of this research work is to investigate the seismic performance of a multistoried reinforced concrete moment resisting framed building under static and dynamic loading as per Bangladesh National Building Code (BNBC, 2006). Static seismic load has been applied to the structure according to Equivalent static force (ESF) method. On the other hand, response spectrum (RS) method has been performed for the application of dynamic loading. The present study focuses on investigating the variation of storey-displacement and storey drift for each storey, base shear, bending moments and shear forces in columns at different storey level. Finally, a comparative study has been carried out between static and dynamic analysis. Based on computing modeling output data, it has been found that the base shear obtained from RS analysis is less compared to ESF method. Maximum storey-displacement obtained from dynamic RS analysis is about 78% of that of static analysis. At the same time, in case of maximum bending moment in an interior column, the dynamic value is approximately 87% of the static value.

κέλυφος, το οποίο συνεχίζει να ερειπώνεται για 14 χρόνια. Ενα τοπόσημο, στην
κατοχή της εθνικής τράπεζας, μετά τη χρεωκοπία της επιχείρησης που στέγαζε.
Έκτοτε έχει αποτύχει να πωληθεί σε δεκάδες πληστειριασμούς, ενώ οι εργαζόμενοι
περιμένουν ακόμα τις αποζημιώσεις τους.
Πρόκειται για την καπνοβιομηχανία Γ.Α. Κεράνης, η οποία λειτούργησε 80

Η θέση του στον πολεοδομικό ιστό είναι κομβικής σημασίας. Βρίσκεται βόρεια από ένα απροσπέλαστο όριο, άυτο της Πειραιώς. Σε συνδυασμό με την λεωφόρο
Μικράς Ασίας και τον σιδηρόδρομο που χαράσσεται ανάμεσα στους δυο,
υπερτοπικής σημασίας, δρόμους, υψώνει ένα νοητό τείχος ενδιάμεσα του κέντρου του Πειραιά και της περιοχής των Καμινιών, της συνοικίας του Κεράνη.
Η πρόταση έχει σκοπό, εκτός της αστικής συρραφής, το κτίριο να λειτουργήσει ως κοινωνικός πυκνωτής, συγκροτώντας σε ενιαίο σύνολο τα σκόρπια μηχανουργεία και βιοτεχνίες, που υπάρχουν στα πέριξ του Κεράνη, εντάσσοντας τα σε ένα στεγασμένο βιοτεχνικό πάρκο, που θα λειτουργήσει στους χαμηλότερους ορόφους του κτιρίου.

description: Computational Colour Constancy (CCC) consists of estimating the colour of one or more illuminants in a scene and using them to remove unwanted chromatic distortions. Much research has focused on illuminant estimation for CCC on single images, with few attempts of leveraging the temporal information intrinsic in sequences of correlated images (e.g., the frames in a video), a task known as Temporal Colour Constancy (TCC). The state-of-the-art for TCC is TCCNet, a deep-learning architecture that uses a ConvLSTM for aggregating the encodings produced by CNN submodules for each image in a sequence. We extend this architecture with different models obtained by (i) substituting the TCCNet submodules with C4, the state-of-the-art method for CCC targeting images; (ii) adding a cascading strategy to perform an iterative improvement of the estimate of the illuminant. We tested our models on the recently released TCC benchmark and achieved results that surpass the state-of-the-art. Analyzing the impact of the number of frames involved in illuminant estimation on performance, we show that it is possible to reduce inference time by training the models on few selected frames from the sequences while retaining comparable accuracy.

description: Algebraic models are proposed for the description of the shell-like quarteting of the nucleons both on the phenomenologic and on the semimicroscopic levels. In the previous one the quartet is considered as a structureless object, while in the latter one its constituents are treated explicitely. The excitation spectrum is generated by the SU(3) formalism in both cases. An application to the $^{20}$Ne nucleus is presented.

description: Bezrukavnikov and Kaledin introduced quantizations of symplectic varieties X in positive characteristic which endow the Poisson bracket on X with the structure of a restricted Lie algebra. We consider deformation quantization of line bundles on Lagrangian subvarieties Y of X to modules over such quantizations. If the ideal sheaf of Y is a restricted Lie subalgebra of the structure sheaf of X, we show that there is a certain cohomology class which vanishes if and only if a line bundle on Y admits a quantization.

A Comic Approach to Politics? Political Education via Comics

Publisher: name: JSSE - Journal of Social Science Education
Year: 2009

description: This article examines juvenile comics that deal with politics as a main topic. These comics introduce and develop politicised themes and topics in varying ways and their individual approaches to politics will be discussed and analysed. The first example, the German Micky Maus-Magazin series, occasionally uses political matters to create new comical stories. In the issues discussed here, democratic processes in the fictional city of Duckburg are described. The second example, Andi, published by the Interior Ministry of the State of North Rhine-Westphalia, aims at civic education. This comic explores the very real issues of rightwing extremism and rightwing propaganda within a fictional framework. The third example, Persepolis treats political issues in a serious, but not primarily pedagogical, way. It offers a personal viewpoint on the Iranian revolution in 1979. By reflecting on Iranian society, the Iranian author puts forward new perspectives on the country which are quite opposite to those that are typically represented in Western countries’ daily news. All three comics provide varying degrees of understanding on politics and political processes. Since each example combines elements of entertainment with political information, they will be analysed within the theoretical framework of what Dörner defines as politainment.

description: Observed kinematical data of 40 Local Group (LG) members are used to derive the dark matter halo mass of such galaxies. Haloes are selected from the theoretically expected LG mass function and two different density profiles are assumed, a standard universal cuspy model and a mass dependent profile which accounts for the effects of baryons in modifying the dark matter distribution within galaxies. The resulting relations between stellar and halo mass are compared with expectations from abundance matching. Using a universal cuspy profile, the ensemble of LG galaxies is fit in relatively low mass haloes, leaving "dark" many massive haloes of \mhalo$\gtrsim$10$^{10}$\msun: this reflects the "too big to fail" problem and results in a \mstar-\mhalo\ relation that differs from abundance matching predictions. Moreover, the star formation efficiency of isolated LG galaxies increases with decreasing halo mass when adopting a cuspy model. By contrast, using the mass dependent density profile, dwarf galaxies with \mstar$\gtrsim$10$^{6}$\msun are assigned to more massive haloes, which have a central cored distribution of dark matter: the "too big to fail" problem is alleviated, the resultant \mstar-\mhalo\ relation follows abundance matching predictions down to the completeness limit of current surveys, and the star formation efficiency of isolated members decreases with decreasing halo mass, in agreement with theoretical expectations. Finally, the cusp/core space of LG galaxies is presented, providing a framework to understand the non-universality of their density profiles.

description: We provide results demonstrating the smoothness of some marginal log-linear parameterizations for distributions on multi-way contingency tables. First we give an analytical relationship between log-linear parameters defined within different margins, and use this to prove that some parameterizations are equivalent to ones already known to be smooth. Second we construct an iterative method for recovering joint probability distributions from marginal log-linear pieces, and prove its correctness in particular cases. Finally we use Markov chain theory to prove that certain cyclic conditional parameterizations are also smooth. These results are applied to show that certain conditional independence models are curved exponential families.

description: Transverse Kerker effect is known by the directional scattering of an electromagnetic plane wave perpendicular to the propagation direction with nearly suppression of both forward and backward scattering. Compared with plane waves, localized electromagnetic emitters are more general sources in modern nanophotonics. As a typical example, manipulating the emission direction of a quantum dot is of virtue importance for the investigation of on-chip quantum optics and quantum information processing. Herein, we introduce the concept of transverse Kerker effect of localized electromagnetic sources utilizing a subwavelength dielectric antenna, where the radiative power of magnetic, electric and more general chiral dipole emitters can be dominantly directed along its dipole moment with nearly suppression of radiation perpendicular to the dipole moments. Such transverse Kerker effect is also associated with Purcell enhancement mediated by electromagnetic multipolar resonances induced in the dielectric antenna. Analytical conditions of transverse Kerker effect are derived for the magnetic dipole, electric dipole and chiral dipole emitters. We further provide microwave experiment validation for the magnetic dipole emitter. Our results provide new physical mechanisms to manipulate the emission properties of localized electromagnetic source which might facilitate the on-chip quantum optics and beyond.

In particular, we present our predictions for the rapidity distribution for rh0 and phi photoproduction and perform an analysis on the uncertainties associated to the choice of vector meson wavefunctionand the phenomenological models for the dipole cross section. Comparison is done with the recent ALICE analysis on coherent production of rho at 2.76 TeV in PbPb collisions.

description: Towards the goal of extracting the continuum properties, we have studied the Topological Charge Density Correlator (TCDC) and the Inverse Participation Ratio (IPR) for the topological charge density ($q(x)$) in SU(3) Lattice Yang-Mills theory for relatively small lattice spacings including some smaller than those explored before. With the help of recently proposed open boundary condition, it is possible to compute observables at a smaller lattice spacing since {\em trapping problem} is absent. On the other hand, the reference energy scale provided by Wilson flow allows us to study their scaling behavior in contrast to previously proposed smearing techniques. The behavior of TCDC for different lattice spacings at a fixed HYP smearing level shows apparent scaling violations. In contrast, at a particular Wilson flow time $t$ for all the lattice spacings investigated (except the largest one), the TCDC data show universal behavior within our statistical uncertainties. The continuum properties of TCDC are studied by investigating the small flow time behavior. We have also extracted the pseudoscalar glueball mass from TCDC, which appears to be insensitive to the lattice spacings (0.0345 fm $\leq a\leq$ 0.0667 fm) and agrees with the value extracted using anisotropic lattices, within statistical errors. Further, we have studied the localization property of $q(x)$ through IPR whose continuum behavior can be probed through the small values of Wilson flow time and observed the decrease of IPR with decreasing Wilson flow time. A detailed study of $q(x)$ under Wilson flow time revealed that as Wilson flow time decreases, the proximity of the regions of positive and negative charge densities of large magnitudes increases, and the charge density appears to be more delocalized resulting in the observed behavior of IPR.

title: Produktkauf vs. Arztwahl
Creators: name: Kratzer, Nadine
Year: 2022

description: Online-Bewertungen finden sich mittlerweile zu beinahe jedem denkbaren Themengebiet. Nicht bloß Restaurants, Produkte oder Dienstleistungen erhalten Feedback, auch Ärzt*innen wird dies vermehrt zuteil. Ziel dieser Arbeit ist es, herauszufinden, inwiefern die Variablen Volumen und Valenz der Bewertungen einerseits in Bezug auf die Kaufintention und andererseits für die Auswahl von Ärzt*innen von Relevanz sind. Außerdem gilt es, die Bedeutsamkeit der Online-Bewertungen in den Kontexten „Produktkauf“ und „Arztwahl“ zu vergleichen. Zur Überprüfung der Hypothesen wurde mittels SoSci Survey ein standardisierter Online-Fragebogen entwickelt. Die Teilnehmer*innen wurden gezielt zu ihrer Internetnutzung, ihren Erfahrungen mit Produkt- und Arztbewertungen und ihrer Relevanzeinschätzung befragt. Das Sample umfasst dabei 255 Personen zwischen 20 und 25 Jahren. Die Ergebnisse weisen darauf hin, dass positive Online-Bewertungen im Vergleich zu negativen und ausgeglichenen eher zu einer Kaufintention führen. Dies gilt sowohl für den Kontext Produktkauf als auch die Auswahl von Ärzt*innen. Hinsichtlich des Volumens lässt sich feststellen, dass die Befragten eher Produkte mit vielen (>5) Bewertungen als mit wenigen oder gar keinen kaufen würden. Ebenso in Bezug auf die Wahl von Ärzt*innen. In der Gegenüberstellung zeigt sich, dass entgegen der angenommenen Hypothese, Online-Bewertungen in Zusammenhang mit Produkten von höherer Relevanz sind als bei der Auswahl von Ärzt*innen. Auf die Bedeutsamkeit weiterer Forschung im Zusammenhang mit Online-Bewertungen sei hier abschließend hingewiesen. Dabei sei vor allem ein Augenmerk auf den unmittelbaren Kontextvergleich gelegt.
title: Mediierender Effekt von Alkoholkonsum auf die Impulsivität bei Personen mit Binge-Eating-Störung?
Creators: name: Brandl, Cornelia
Year: 2022

description: Hintergrund. Binge-Eating-Störung (BED) ist eine der häufigsten Essstörungen, die durch exzessive Nahrungsaufnahmen gekennzeichnet ist und von Kontrollverlustgefühlen begleitet wird. Damit verbunden ist eine Reihe von physischen, aber auch psychischen und sozialen Problemen, darunter auch Suchtverhalten und speziell der missbräuchliche Konsum von Alkohol. Studien zeigen eine Assoziation zwischen der Bewältigung negativer Emotionen, Alkoholkonsum und dem Konstrukt der Impulsivität, das auch bei Binge Eating eine wichtige Rolle spielt. Auch Unsicherheitsintoleranz (UI), die Tendenz, ungewisse Situationen als bedrohlich wahrzunehmen, ist in diesem Zusammenhang von großer Bedeutung. Methodik. Um den Einfluss von Alkoholkonsum auf Impulsivität und Unsicherheitsintoleranz bei Personen mit BED an der vorliegenden Stichprobe (N=182) zu erfassen, wurden Daten im Rahmen einer Online-Fragebogenstudie mittels Eating Disorder Examination Questionnaire (EDE-Q), Alcohol Use Disorders Identification Test (AUDIT-GM-AT), Unsicherheitsintoleranzskala-18 (UI-18) sowie der UPPS Impulsive Behavior Scale erfasst. Ergebnisse. Entgegen den Erwartungen war die Geschlechterverteilung in dieser Stichprobe nicht ausgeglichen. Es konnte auch kein vermehrter Alkoholkonsum bei Personen mit BED im Vergleich zu Gesunden festgestellt werden. Den Erwartungen entsprechend wiesen Personen mit BED in dieser Stichprobe signifikant höhere UI-Werte und Impulsivitätswerte im Vergleich zu Gesunden auf. Erwartungswidrig war, dass Personen mit BED und gleichzeitigem missbräuchlichen Alkoholkonsum gleich hohe Werte in Bezug auf Impulsivität sowie Unsicherheitsintoleranz wie Personen mit BED ohne gleichzeitigen missbräuchlichen Alkoholkonsum aufwiesen. Das Verhältnis zwischen UI und BED-Symptomatik wurde auf Basis der Ergebnisse dieser Stichprobe nicht durch Alkoholkonsum mediiert. Entgegen den Annahmen aufgrund bisherigerer Studienergebnisse war auch kein mediierender Effekt von Alkoholkonsum auf die Impulsivität bei Personen mit BED nachweisbar. Schlussfolgerungen. Die Erhebung mittels Online-Studie, nicht erfasste, eventuell vorliegende Komorbiditäten sowie die Zuordnung zur Essstörungsgruppe auf Basis von Ergebnissen der Fragebögen im Selbstbericht könnten neben dem Erhebungszeitraum ausschlaggebend für die Resultate sein. Weitere Untersuchungen an ausgeglichenen Stichproben sind nötig, um aussagekräftige Ergebnisse zu erzielen.

description: A panoptic driving perception system is an essential part of autonomous driving. A high-precision and real-time perception system can assist the vehicle in making the reasonable decision while driving. We present a panoptic driving perception network (YOLOP) to perform traffic object detection, drivable area segmentation and lane detection simultaneously. It is composed of one encoder for feature extraction and three decoders to handle the specific tasks. Our model performs extremely well on the challenging BDD100K dataset, achieving state-of-the-art on all three tasks in terms of accuracy and speed. Besides, we verify the effectiveness of our multi-task learning model for joint training via ablative studies. To our best knowledge, this is the first work that can process these three visual perception tasks simultaneously in real-time on an embedded device Jetson TX2(23 FPS) and maintain excellent accuracy. To facilitate further research, the source codes and pre-trained models are released at https://github.com/hustvl/YOLOP.
Gelingende Lehrerbildung – Professionstheorie und Fachdidaktik, Erfahrungen und Konsequenzen

description: Handlungsprobleme des Lehrers sind zum einen allgemeine konfligierende Ansprüche an die Lehrerrolle, zum anderen fachspezifische Anforderungen an das Unterrichten (strukturtheoretisches bzw. kompetenztheoretisches Professionsverständnis). Konflikte müssen reflexiv balanciert werden, professionelles Unterrichten verlangt Wissen, Können und Reflexion. Fachdidaktische Prinzipien formulieren den Zusammenhang in fachspezifischer Weise. Lehrerbildung muss das Wechselspiel von Theorie und Praxis von Anfang an und durch alle Phasen, wenn auch mit unterschiedlichen Gewichten, verwirklichen. Denn Theorie bleibt ohne Praxis unbegriffen, Praxis bleibt ohne Theorie blind in Krisen und für Veränderungen; Reflexion verweist das eine aufs andere. Unterrichten involviert ganze Personen, weshalb die Ausbildung das Risiko von Kränkungen besonders in der Referendarzeit mit sich bringt. Für die Ausbildung durch die Universität ist zu fordern, dass die Hochschullehrer nicht nur wissen, sondern auch können, also selbst ausgebildete Professionelle sind. Seminarausbilder wiederum müssen auch theorienah reflektieren können, also nicht bloß praktizieren. The teacher has to deal with generally conflicting expectations and with the specific tasks of teaching a subject (theories of structural understanding versus theories of teaching competence of the profession). Conflicts call for reflexive balancing, professional teaching needs knowledge, routines and reflexions. Content-specific didactical principles describe and explain the linkage between these three dimensions. Teachers’ education has to realize the switch of theoretical and practical approaches in every phase, no matter that the emphasis might differ. Thinking without doing remains to be just words, doing without theoretical thinking will remain blind in the cases of crisis and changes. Reflexion links the one to the other and vice versa. Teaching is done for and by whole persons. Therefore the risk of humiliation is very present especially during the practical phases. University teachers teaching to-be-teachers should be educated professionals themselves and not only gifted scholars. School teachers in teachers’ education should be able to reflect on teaching with theoretical means.

description: Using the infinite density matrix renormalization group method on an infinite cylinder geometry, we characterize the $1/3$ fractional Chern insulator state in the Haldane honeycomb lattice model at $ν=1/3$ filling of the lowest band and check its stability. We investigate the chiral and topological properties of this state through (i) its Hall conductivity, (ii) the topological entanglement entropy, (iii) the $U(1)$ charge spectral flow of the many body entanglement spectrum, and (iv) the charge of the anyons. In contrast to numerical methods restricted to small finite sizes, the infinite cylinder geometry allows us to access and characterize directly the metal to fractional Chern insulator transition. We find indications it is first order and no evidence of other competing phases. Since our approach does not rely on any band or subspace projection, we are able to prove the stability of the fractional state in the presence of interactions exceeding the band gap, as has been suggested in the literature. As a by-product we discuss the signatures of Chern insulators within this technique.

description: L’enseignement d’une LCE est un défi difficile à relever dans un contexte culturel et social particulier avec l’allemand dont la portée ne suscite pas un investissement spontané de l’élève. De manière générale, la démotivation peut provoquer la frustration de l’apprenant, celui de l’enseignant, et finalement entraver la dynamique constructive de la progression de l’apprentissage. Les méthodes traditionnelles dans l’enseignement de la littérature se heurtent à ce problème car elles ne parviennent à éveiller que partiellement l’intérêt. Selon des études récentes, un élément clé du succès est directement lié à la notion d’engagement de la part de l’élève, catégorisé selon quatre différents types dans la littérature. Basé sur ce concept de l’engagement, ce mémoire analyse la transition partant de la démarche traditionnelle pour aboutir à la perspective actionnelle, passant par des outils comme la tâche pédagogique, le rôle de l’enseignant, le choix du support, la démarche pédagogique ou encore la forme de travail, suscitant au bout du compte le coeur de la finalité, à savoir l’investissement personnel. Quatre séquences d’enseignement de la littérature germanophone au niveau gymnasial ont été filmées et analysées selon les critères observables relatifs à un modèle global d’engagement issu des théories de la motivation. Partant d’un désengagement notable par la méthode traditionnelle, on constate une évolution vers une dynamique d’engagement forte par la perspective actionnelle. Un enseignement faisant sens aux yeux des élèves, le travail en groupe, l’investissement dans une démarche de projet aboutissant à la création de produits authentiques en sont des éléments clés. Il en résulte une forte motivation intrinsèque et soutenue tout au long de la tâche, liant plaisir et satisfaction à l’acquisition des connaissances et des compétences en LCE.

description: We introduce GRiD: a GPU-accelerated library for computing rigid body dynamics with analytical gradients. GRiD was designed to accelerate the nonlinear trajectory optimization subproblem used in state-of-the-art robotic planning, control, and machine learning, which requires tens to hundreds of naturally parallel computations of rigid body dynamics and their gradients at each iteration. GRiD leverages URDF parsing and code generation to deliver optimized dynamics kernels that not only expose GPU-friendly computational patterns, but also take advantage of both fine-grained parallelism within each computation and coarse-grained parallelism between computations. Through this approach, when performing multiple computations of rigid body dynamics algorithms, GRiD provides as much as a 7.2x speedup over a state-of-the-art, multi-threaded CPU implementation, and maintains as much as a 2.5x speedup when accounting for I/O overhead. We release GRiD as an open-source library for use by the wider robotics community.

We study in detail the behavior of thermodynamically relevant quantities such as heat currents and mean energies of the oscillators, establishing rigorous analytical conditions for the existence of a steady state, whose features we analyse carefully. In particular we assess the conditions that should be faced to recover trends reminiscent of the classical Fourier law of heat conduction and highlight how such a possibility depends on the environment linked to our system.

description: The static properties, i.e., existence and stability, as well as the quench-induced dynamics of vortex-bright type excitations in two-dimensional harmonically confined spin-1 Bose-Einstein condensates are investigated. Linearly stable vortex-bright-vortex and bright-vortex-bright solutions arise in both antiferromagnetic and ferromagnetic spinor gases upon quadratic Zeeman energy shift variations. Their deformations across the relevant transitions are exposed and discussed in detail evincing also that emergent instabilities can lead to pattern formation. Spatial elongations, precessional motion and spiraling of the nonlinear excitations when exposed to finite temperatures and upon crossing the distinct phase boundaries, via quenching of the quadratic Zeeman coefficient, are unveiled. Spin-mixing processes triggered by the quench lead, among others, to changes in the waveform of the ensuing configurations. Our findings reveal an interplay between pattern formation and spin-mixing processes being accessible in contemporary cold atom experiments.

description: This paper aims to explore the importance of accessibility for people with disabilities in achieving the Sustainable Development Goals (SDGs) and to identify accessible resources that have contributed to the achievement of the SDGs for people with disabilities. This study investigates the need for increased investment, collaboration, and awareness to ensure that no one is left behind in the pursuit of sustainable development for people with disabilities. The paper also examines the relationship between disability and specific SDGs, including SDG 4 (Quality Education), SDG 8 (Decent Work and Economic Growth), SDG 10 (Reduced Inequalities), SDG 11 (Sustainable Cities and Communities), and SDG 17 (Partnerships for the Goals), and how achieving these SDGs can positively impact people with disabilities and the world as a whole. Additionally, the challenges and opportunities in providing accessible resources for people with disabilities are discussed, and the role of library and information centers in providing accessible resources is identified. The paper concludes that accessibility is crucial for people with disabilities to achieve their full potential and contribute to the achievement of the SDGs. To ensure that accessibility is integrated into all aspects of the SDGs, there is a need for increased awareness, investment, and collaboration across sectors. By promoting accessibility, we can create a more inclusive and sustainable world where all people, including those with disabilities, can achieve their full potential and contribute to the achievement of the SDGs.

description: La littérature en traduction constitue un domaine de recherche à part entière (OLT), intimement lié aux littératures comparées, mais demeure un aspect largement sous-estimé dans l’enseignement du français au niveau postobligatoire. La question des langues, en général mais en littérature particulièrement, cristallise non seulement les tensions interdisciplinaires mais aussi des tensions internes à l’enseignement du français. Cependant, les possibilités d’utilisation de textes traduits sont nombreuses et les pistes didactiques infinies. Pour notre part, nous avons pris le parti de nous inscrire dans une voie médiane, entre les défenseurs exclusifs de la littérature française et les partisans d’une littérature sans aucune frontière linguistique, culturelle ou nationale. En effet, nous pensons que les littératures ont toujours dialogué, de la même manière que les cultures, se sont enrichies au contact des autres, et que la découverte de textes et d’auteurs étrangers devrait permettre de consolider sa littérature propre. Poe est « découvert » par le truchement de Baudelaire, qui se nourrit lui-même de cette découverte en s’affiliant à l’auteur américain, tandis que Mallarmé tient pour modèle les deux écrivains. Comparer le traitement que réserve chacun de ces poètes à un même sujet et les jeux d’influence entre eux devrait constituer un miroir didactique, où les élèves sont amenés à expérimenter une forme d’altérité dans l’analyse, à s’en enrichir pour ensuite créer un texte et consolider leurs compétences en français.
Kompetenzorientierte Lehrerbildung in den sozialwissenschaftlichen Unterrichtsfächern – Blühende Landschaften in der Lehrerbildung von morgen?

description: Die Erwartungen, die mit einer kompetenzorientierten Lehrerbildung verbunden werden, sind ausgesprochen hoch, teilweise euphorisch. Beim Rezipieren der Literatur entsteht der Eindruck einer blühenden Zukunft der Lehrerbildung. Ist aber die Hinwendung zu einer an Kompetenzen und Standards ausgerichteten, outputorientierten Lehrerbildung der Königsweg aus der Misere im Bildungssystem? Zweifel sind meines Erachtens angebracht. Im Aufsatz werden unter Bezugnahme auf die Lehrerbildung für die sozialwissenschaftlichen Fächer drei Thesen diskutiert, die im Kontext der Debatte um Kompetenzen und Standards oft als Legitimation angeführt werden: (1) Externe Monitoringverfahren im Rahmen der Outputsteuerung verbessern die Qualität der Lehrerbildung, (2) Kompetenzorientierung ist eine „erfolgreiche Forschungsstrategie“ und (3) Kompetenzorientierte Lehrerausbildung führt zu einer Qualitätssteigerung des Schulunterrichts. The expectations which are associated with a competence-oriented teacher’s training are extremely high, partly euphoric. When absorbing the literature the impression is gained of a blooming future for teacher’s training. Is however the devotion to a teacher’s training which is oriented to competences and standards and output-oriented the best way out of the misery in the education system? Doubts are reasonable here in my opinion. Three theses are discussed in the essay by referring to teacher’s training for social science subjects, which are often mentioned as legitimation in the context of the debate concerning competences and standards: (1) External monitoring procedures within the framework of the output control improve the quality of teacher’s training, (2) Competence-orientation is a „successful research strategy“ and (3) Competence-oriented teacher’s training leads to an improvement in quality of the school lessons.

Radiative heat transfer in nonlinear Kerr media

description: We obtain a fluctuation--dissipation theorem describing thermal electromagnetic fluctuation effects in nonlinear media that we exploit in conjunction with a stochastic Langevin framework to study thermal radiation from Kerr ($χ^{(3)}$) photonic cavities coupled to external environments at and out of equilibrium. We show that that in addition to thermal broadening due to two-photon absorption,the emissivity of such cavities can exhibit asymmetric,non-Lorentzian lineshapes due to self-phase modulation. When the local temperature of the cavity is larger than that of the external bath, we find that the heat transfer into the bath exceeds the radiation from a corresponding linear black body at the same local temperature. We predict that these temperature-tunable thermal processes can be observed in practical, nanophotonic cavities operating at relatively small temperatures.
12 Jahre Berufserfahrung – Die besondere Situation des Lehramtsstudiums als Herausforderung für die fachdidaktische Ausbildung

description: Es gehört zur besonderen Situation des Lehramtsstudiums, dass die Studierenden hier bereits zu Beginn ihrer Ausbildung über mindestens 12 Jahre Erfahrung mit schulischen Lernprozessen verfügen. Dass sie diese Lernprozesse fast ausschließlich aus der Perspektive der Lernenden und nicht der Perspektive der Lehrenden kennen, hindert sie dabei nicht daran, sich z.T. bereits ausgefeilte Vorstellungen darüber zu bilden, wie solche Lernprozesse sinnvoll zu gestalten sind. Mit fachdidaktischen Theorien haben diese Vorstellungen häufig wenig gemeinsam, obwohl sie je nach fachlichem Gegenstand durchaus differenziert strukturiert sind. In meinem Beitrag möchte ich mich mit diesen Vorstellungen beschäftigen und aufzeigen, wie diese im Rahmen fachdidaktischer Einführungsveranstaltungen fruchtbar gemacht werden könnten. It belongs to the special situation of teacher studies that students already at the beginning of their training have at least 12 years experience with school learning processes. Even if they know these learning processes almost exclusively from the perspective of pupils and not from the perspective of teachers, it does not prevent them from forming partially sophisticated conceptions how to arrange such learning processes. These conceptions are hardly connected with educational theories, although they differ in structure depending on the topic. In my essay I would like to be concerned wih these conceptions and I want to point out, how this could be made useful in the context of educational introduction tutorials.

"… aber das klappt nicht in der Schulpraxis!" Skizze einer kompetenz- und fallorientierten Hochschuldidaktik für die Politiklehrer-Ausbildung
Creators: name: Petrik, Andreas
Publisher: name: JSSE - Journal of Social Science Education

description: Der Politikdidaktik fehlen bisher hochschuldidaktische Lehrstandards für eine effektive Politiklehrerausbildung. Auf der Ziel- und Inhaltsebene werden vier Lehrer-Kompetenzen vorgeschlagen: Analysekompetenz, Inszenierungskompetenz (Methoden- und Planungskompetenz), Aushandlungskompetenz und Diagnosekompetenz. Deren Ausgestaltung umreißt zugleich ein mögliches Theorie- und Methodencurriculum. Hochschulmethodisch gilt es, einen ersten, universitären Praxisschock zu inszenieren, um die Beharrlichkeit bestimmter vordidaktischer Alltagstheorien aufzuweichen. Dazu wird ein Konzept doppelter Fallorientierung vorgestellt: 1. Basismodul: In Lehrkunstwerkstätten Best-Practice-Modelle durchspielen, die den politikdidaktischen Methodenfundus und die dahinterliegende konzeptionelle Ebene exemplarisch-genetisch aufschließen (Analyse- und Methodenkompetenz). 2. Aufbaumodul: An Unterrichtsszenen und biografischem Material Lehr-Lern-Probleme bearbeiten (Diagnose- und Aushandlungskompetenz). The German social studies education is still missing university standards for teaching prospective teachers in pedagogical content knowledge and subject methodology. The author proposes four competencies each social studies teacher should develop: Analytical skills (application of didactic theories), methodical and planning skills (to „direct“ lessons), negotiation skills (for teaching) and diagnostic skills. A university program for social studies education should be able to provoke conceptual changes to alter the student’s partly oversimplified and pre-didactical beliefs. For this purpose the author presents a dual conception of case study work: 1. In a basic course students try out best-practice teaching units in microteaching scenarios. Hereby they acquire a set of basic methods and the didactic theories behind them (analytical and methodical skills). 2. In an advanced course students examine biographic material (of students and teachers) and transcriptions of typical classroom scenes to understand content related learning and teaching problems (diagnostic and negotiation skills).

description: This work introduces the high-order Boris-SDC method for integrating the equations of motion for electrically charged particles in an electric and magnetic field. Boris-SDC relies on a combination of the Boris-integrator with spectral deferred corrections (SDC). SDC can be considered as preconditioned Picard iteration to compute the stages of a collocation method. In this interpretation, inverting the preconditioner corresponds to a sweep with a low-order method. In Boris-SDC, the Boris method, a second-order Lorentz force integrator based on velocity-Verlet, is used as a sweeper/preconditioner. The presented method provides a generic way to extend the classical Boris integrator, which is widely used in essentially all particle-based plasma physics simulations involving magnetic fields, to a high-order method. Stability, convergence order and conservation properties of the method are demonstrated for different simulation setups. Boris-SDC reproduces the expected high order of convergence for a single particle and for the center-of-mass of a particle cloud in a Penning trap and shows good long-term energy stability.
