description: Der folgende Beitrag stellt nach einer thematischen Einführung die ersten beiden Doppelstunden der Unterrichtseihe „Regenwurmforscher auf Marsmission“ vor. In dieser Unterrichtsreihe wird den Schülerinnen und Schülern selbst die Forscherrolle übertragen. In der ersten Doppelstunde wird dabei zunächst Fachwissen zur Biologie des Regenwurms, zu den Methoden der Erkenntnisgewinnung, zum Forschungsprozess und zum zugehörigen Forschungskontext erarbeitet. Als Forschungskontext dient ein aktuelles Projekt der Marsforschung, den Boden auf dem Mars mithilfe von Regenwürmern fruchtbar machen zu können, damit dort Nahrungs- und Nutzpflanzen angebaut werden könnten. Um die Eignung der Regenwürmer in diesem Kontext praktisch zu prüfen, liegt der Schwerpunkt der zweiten Doppelstunde auf der Methode des Experimentierens. Versuche mit dem Modellorganismus Dendrobena veneta werden dabei eigenständig durchgeführt und ausgewertet. Die vorgestellten Versuche dieses Artikels beinhalten in diesem Zusammenhang u.a. das Herstellen eines eigenen „Marsterrariums“ zur Langzeitbeobachtung und eine Reihe von Experimenten zu den Themen Atmungsorgan der Regenwürmer sowie Temperaturempfinden und Fortbewegung der Regenwürmer.

description: The recent measurements of the neutrino reactor angle require a re-examination of flavour models based on discrete groups. Indeed, when these models deal with the Tri-Bimaximal, the Bimaximal and the Golden Ratio mixing patterns, some tensions arise in order to accommodate the reactor angle. In particular, strong constraints come from lepton flavour violating processes, like mu -> e gamma. We present the analysis and the main results.

Convex sublattices of a lattice and a fixed point property

Publisher: name: Faculty of Science, University of Calgary

description: The collection CL(T) of nonempty convex sublattices of a lattice T ordered by bi-domination is a lattice. We say that T has the fixed point property for convex sublattices (CLFPP for short) if every order preserving map f from T to  CL(T) has a fixed point, that is x > f(x) for some x > T. We examine which lattices may have CLFPP. We introduce the selection property for convex sublattices (CLSP); we observe that a complete lattice with CLSP must have  CLFPP, and that this property implies that CL(T) is complete. We show that for a lattice T, the fact that CL(T) is complete is equivalent to the fact that T is complete and the lattice of all subsets of a countable set, ordered by containment, is not order embeddable into T. We show that for the lattice T = I(P) of initial segments of a poset P, the implications above are equivalences and that these properties are equivalent to the fact that P has no infinite antichain. A crucial part of this proof is a straightforward application of a wonderful Hausdor type result due to Abraham, Bonnet, Cummings, Dzamondja and Thompson [2010].

description: An antenna can be modeled as a two-port network using S-parameters. However, having antenna S-parameters are not sufficient for modeling an array of antennas as that requires mutual coupling. This thesis proposes a network model to represent an antenna array including mutual coupling. Using the proposed model, an N-element antenna array can be modeled as a combination of two-port networks to represent each element and an N-port network to represent mutual coupling. In this thesis, the operation of the proposed model is explained and the concept of complete antenna array scattering matrix representation is introduced. Two techniques to calculate mutual coupling S-parameters are presented: primary method using numerical solutions and general method using general expressions. The proposed model was validated with reference to the radiation efficiency and S-parameters between the physically accessible ports using several arrays: various inter-element lengths, varying the number of elements and configurations, and non-identical array elements.

description: Although Global Positioning System (GPS) has been widely used to land vehicle navigation systems, GPS is unable to provide continuous and reliable navigation solutions in the presence of signal fading and/or blockage such as in urban areas. With the advent of the Micro-Electro-Mechanical System (MEMS) Inertial Navigation System (INS), a low-cost MEMS INS/GPS integration system becomes available to provide improved navigation performance by integrating the long-term GPS accuracy with the short-term INS accuracy. The challenges to low-cost MEMS INS/GPS integration arise from dealing with the corrupted GPS data in signal-degraded environments, the large instrument errors experienced with low-grade MEMS sensors and the distorted magnetic measurements from an embedded electronic compass. This dissertation develops intelligent data fusion and processing techniques for such a low-cost integration system by incorporating the Artificial Intelligence (AI) with the Kalman filtering. Two cascaded Kalman filters implemented upon a loosely coupled integration scheme are applied to perform data fusion in the velocity/attitude and position domain, respectively. Three AI-based methods are developed for GPS data assessment, INS error control and compass error modelling to enhance the Kalman-filter-based integration. Specifically, a fuzzy GPS data classification system is developed to optimize INS/GPS data fusion through adjusting the measurement covariances of the Kalman filters according to GPS signal degradation conditions. A dynamics knowledge aided inertial navigation algorithm along with a fuzzy expert vehicle dynamics identification system is created to reduce and control INS error drift throu gh simplifying system models and extending measurement update schemes of the Kalman filters. A neural-networks-based compass calibration algorithm is developed to provide the correct compass heading updates to the Kalman filters in the presence of disturbance. The developed algorithms have been tested and evaluated in various GPS conditions, which include open areas, complete GPS outages and urban areas, using a low-cost Xsens MT9 MEMS IMU and SiRF Star II conventional/high sensitivity GPS receivers. The obtained results have confirmed the effectiveness of the AI-based methods and the significant performance improvement by the intelligent integration algorithm. For GPS outages around 3 minutes, the intelligent integration system is able to maintain satisfactory position accuracy with the maximum error less than 30 m. In the typical North American urban canyons, the intelligent integration system can provide continuous and reliable navigation solutions with the horizontal position accuracy of around 15 m. Overall results confirm the benefits and advantages of applying the developed AI methods to assist the low-cost MEMS INS/GPS integration for land vehicle navigation.
B-L Violating Nucleon Decay and GUT Scale Baryogenesis in SO(10)

description: We show that grand unified theories based on SO(10) generate naturally the next-to-leading baryon number violating operators of dimension seven. These operators, which violate B-L, lead to unconventional decays of the nucleon such as n -> e^-K^+, e^- π^+ and p -> νπ^+. In two-step breaking schemes of non-supersymmetric SO(10), nucleon lifetime for decays into these modes is found to be within reach of experiments. We also identify supersymmetric scenarios where these decays may be accessible, consistent with gauge coupling unification. Further, we show that the (B-L)-asymmetry generated in the decays of GUT scale scalar bosons and/or gauge bosons can explain consistently the observed baryon asymmetry of the universe. The induced (B-L)-asymmetry is sphaleron-proof, and survives down to the weak scale without being erased by the electroweak interactions. This mechanism works efficiently in a large class of non-SUSY and SUSY SO(10) models, with either a 126 or a 16 Higgs field employed for rank reduction. In minimal models the induced baryon asymmetry is tightly connected to the masses of quarks, leptons and neutrinos and is found to be compatible with observations.

Our results are valid for operators of arbitrary size. In particular, we study the limit in which two of the four operators are taken to be much smaller than the others. We show that in this limit our weak coupling result matches with the strong coupling result in the Frolov-Tseytlin limit.

description: How has metabolomics helped our understanding of infectious diseases? With the threat of antimicrobial resistance to human health around the world, metabolomics has emerged as a powerful tool to comprehensively characterize metabolic pathways to identify new drug targets. However, its output is constrained to known metabolites and their metabolic pathways. Recent advances in instrumentation, methodologies, and computational mass spectrometry have accelerated the use of metabolomics to understand pathogen-host metabolic interactions. This short review discusses a selection of recent publications using metabolomics in infectious/bacterial diseases. These studies unravel the links between metabolic adaptations to environments and host metabolic responses. Moreover, they highlight the importance of enzyme function and metabolite characterization in identifying new drug targets and biomarkers, as well as precision medicine in monitoring therapeutics and diagnosing diseases.
BUFFing signature schemes beyond unforgeability and the case of post-quantum signatures

description: Modern digital signature schemes can provide more guarantees than the standard notion of(strong) unforgeability, such as offering security even in the presence of maliciously generated keys, or requiring to know a message to produce a signature for it. The use of signature schemes that lack these properties has previously enabled attacks on real-world protocols. In this work we revisit several of these notions beyond unforgeability, establish relations among them, provide the first formal definition of nonre-signability, and a transformation that can provide these properties for a given signature scheme in a provable and efficient way.Our results are not only relevant for established schemes: for example, the ongoing NIST PQC competition towards standardizing post-quantum signature schemes has six finalists in its third round. We perform an in-depth analysis of the candidates with respect to their security properties beyond unforgeability. We show that many of them do not yet offer these stronger guarantees, which implies that the security guarantees of these post-quantum schemes are not strictly stronger than, but instead incomparable to, classical signature schemes. We show how applying our transformation would efficiently solve this,paving the way for the standardized schemes to provide these additional guarantees and thereby making them harder to misuse.
A Thematic Analysis of Group Trainees and Trainers Experiences of the POGTF

description: Group work is an established approach in social work practice and an efficacious method of intervention for psychosocial problems. With the decline in group education in Canada, and a greater reliance on field instructors to provide group training, there is a need for a training framework that incorporates the complexity of knowledge translation and professional development. In response to this identified need, a training framework was developed to support research-informed practice and experiential learning in group competencies. The current thesis employed a qualitative study to explore group trainees' and field instructors' experiences and perceptions of a training framework, the Participant Observer Group Training Framework (POGTF). Template Thematic Analysis (Brooks et al., 2015) was used to analyze the data. Six main themes emerged from the analysis: (a) the participant observer role provided opportunity for the group trainees to engage in personal growth and professional development through experiential participation in a group; (b) knowledge translation was an essential step in developing structural knowledge, case conceptualization, and professional uses of self; (c) the group trainees who used research to inform practice were more likely to engage in an evidence-based practice process; (d) observation was a key learning pathway for the group trainees; (e) participant observation supported understanding of group processes, but conceptualization of a professional response also required knowledge translation; and (f) group trainees used the participant observer role to learn content and procedural knowledge. The results suggest that the combination of participant observation in groups, the use of a structured critical reflection tool, and weekly supervision supported both personal growth and professional development. Differential learning pathways occurred between group trainees who engaged in observation of group stages and processes alone, and those who additionally linked group events to research or theory. The group trainees in the current thesis did not report learning how to implement, score, or interpret outcome measures. The results suggest that certain components of the training framework were more easily adhered to by the group trainees and trainers in this study, which has implications for group training in field education.

description: A previous inelastic UV scattering experiment on silica glass is reproduced using a high grade superpolished sample. In the pristine sample condition, surface scattering is not observable compared to Rayleigh scattering from the bulk. However, exposure to a fluence of the order of 100 J/cm$^2$ at photon energies slightly below the electronic gap generates observable surface damage. This occurs after a few hours illumination with the monochromatic spectrometer beam. No anomaly in the Brillouin linewidth was found up to an excitation energy of 7.8 eV.

description: Accurate prediction of pedestrian and bicyclist paths is integral to the development of reliable autonomous vehicles in dense urban environments. The interactions between vehicle and pedestrian or bicyclist have a significant impact on the trajectories of traffic participants e.g. stopping or turning to avoid collisions. Although recent datasets and trajectory prediction approaches have fostered the development of autonomous vehicles yet the amount of vehicle-pedestrian (bicyclist) interactions modeled are sparse. In this work, we propose Euro-PVI, a dataset of pedestrian and bicyclist trajectories. In particular, our dataset caters more diverse and complex interactions in dense urban scenarios compared to the existing datasets. To address the challenges in predicting future trajectories with dense interactions, we develop a joint inference model that learns an expressive multi-modal shared latent space across agents in the urban scene. This enables our Joint-b-cVAE approach to better model the distribution of future trajectories. We achieve state of the art results on the nuScenes and Euro-PVI datasets demonstrating the importance of capturing interactions between ego-vehicle and pedestrians (bicyclists) for accurate predictions.

description: Possible manifestation of the family non-universal Z' boson effects in lepton polarization in rare, exclusive baryonic "Lambda_b -> Lambda l+l-" decay is examined. It is observed that the double lepton polarizations P_TT and P_NN are sensitive to the Z' contribution. Moreover, it is found that the zero position of the polarized forward-backward asymmetry A_FB^LL is shifted to the left compared to the standard model prediction. Therefore, determination of the zero value of A_FB^LL is quite an efficient tool for establishing new Z' boson, but also in discriminating various scenarios of the considered family non-universal Z' model.

Geology, geochronology and structural reconstruction of the Cerro Bayo epithermal district, Chilean Patagonia
Creators: name: Poblete, Jaime Andrés
Publisher: name: University of British Columbia
Year: 2011

description: The Cerro Bayo low-sulfidation epithermal district is located in the Aysén region, Chilean Patagonia. The oldest rocks that crop out in the district correspond to mainly rhyolitic fragmental successions of the Jurassic Ibáñez Formation which erupted based on biotite ⁴°Ar/³⁹Ar and zircon U-Pb ages, between ca. 154 and 144 Ma. The veins at Cerro Bayo are spatially associated with N-S aligned rhyolitic domes dated at 146.50±0.21 and 146.3±0.2 Ma (zircon U-Pb), intruding the volcanic rocks. Dacitic domes dated at 83.0±0.21 and 82.6±0.2 Ma (zircon U-Pb) are present to the west of the district at Laguna Verde. Silver and gold mineralization is hosted by steeply dipping N-S to NW trending quartz veins, that were emplaced in three main episodes based on adularia ⁴°Ar/³⁹Ar ages: (1) Mallines: ca. 144-142; (2) Bahía Jara and Brillantes: ca .137-124 Ma; and (3) Laguna Verde: 114-111 Ma. Clay alteration mineralogy around the veins consists of illite±smectite±kaolinite–chlorite. At Mallines the illite+kaolinite–smectite mineral assemblage combined with the high illite crystallinity index indicates that these veins are not deeply eroded and the surface outcrops correspond to high levels within the low-sulfidation epithermal deposit model. At Bahia Jara the illite ± smectite – kaolinite and at Brillantes the illite–chlorite–kaolinite assemblages, and overall lower illite crystallinity indices indicate that the veins in these areas are more deeply eroded than at Mallines. Illite crystallinity index is lower for Brillantes than at Bahía Jara indicating that the level of exposure at Brillantes is deeper than at Bahía Jara. At Laguna Verde the mainly illite – smectite clay alteration assemblage plus the lowest illite crystallinity indices of the entire district indicate higher temperature of formation and, by inference, the most deeply eroded veins of the entire district. The level of exposure of the veins has no relation with age of mineralization and the veins suffered differential degree of uplift and erosion after the Late Cretaceous. Moreover, glacial erosion has not uniformly affected the area. The observed textures and clay alteration assemblages at Mallines indicate important potential at 150–250 m depth if classic published deposit models are considered.
Convolutional Dynamic Alignment Networks for Interpretable Classifications
Creators: name: Böhle, Moritz
name: Fritz, Mario
name: Schiele, Bernt
Publisher: name: CISPA
Year: 2023

description: We introduce a new family of neural network models called Convolutional Dynamic Alignment Networks (CoDA-Nets), which are performant classifiers with a high degree of inherent interpretability. Their core building blocks are Dynamic Alignment Units (DAUs), which linearly transform their input with weight vectors that dynamically align with task-relevant patterns. As a result, CoDA-Nets model the classification prediction through a series of input-dependent linear transformations, allowing for linear decomposition of the output into individual input contributions. Given the alignment of the DAUs, the resulting contribution maps align with discriminative input patterns. These model-inherent decompositions are of high visual quality and outperform existing attribution methods under quantitative metrics. Further, CoDA-Nets constitute performant classifiers, achieving on par results to ResNet and VGG models on e.g. CIFAR-10 and TinyImagenet.
Instability zones for satellites of asteroids. The example of the (87) Sylvia system

description: We study the stability of the (87) Sylvia system and of the neighborhood of its two satellites. We use numerical integrations considering the non-sphericity of Sylvia, as well as the mutual perturbation of the satellites and the solar perturbation. Two numerical models have been used, which describe respectively the short and long-term evolution of the system. We show that the actual system is in a deeply stable zone, but surrounded by both fast and secular chaotic regions due to resonances. We then investigate how tidal and BYORP effects modify the location of the system over time with respect to the instability zones. Finally, we briefly generalize this study to other known triple systems and to satellites of asteroids in general, and discuss about their distance from mean-motion and evection resonances.

description: This thesis examines the statutory framework of the Forest Rights Act in light of India’s obligations under the ILO Convention 107, the CERD, and Article 27 of the ICCPR with respect to tribal land ownership. The Forest Rights Act is an express measure to address the ‘historic injustice’ perpetrated against tribal communities in matters of land rights. This thesis examines whether the Act fulfills India’s human rights obligations under international law, particularly the obligation to recognize and protect the right to tribal ownership in traditional lands. The analysis focuses on two main aspects of India’s obligations: whether the Forest Rights Act fulfills the obligation to fully recognize, delimit and demarcate the right to ownership of forest dwelling tribals based on traditional occupation of forestlands; and, whether the Forest Rights Act fulfills the obligation of effective participation imposed by international law before decisions (including state authorized resource development projects) are undertaken on traditional forest lands? The author concludes that the statutory framework of the Forest Rights Act does not fulfill India’s international human rights obligations with respect to the land rights of forest dwelling tribal communities, in particular with respect to the tribal right to ownership of traditional lands.

description: Im Zuge der Corona-Pandemie wurden weltweit temporären Schulschließungen vorgenommen. Wie funktioniert(e) Bildung in dieser Kri­se? Daten des Schul-Barometers von insgesamt 5.167 Mitarbeitenden an Schulen aus Deutschland, Österreich und der Schweiz ermöglichen einen Einblick in die Rahmenbedingungen von Digitalisierung während des Lehrens und Lernens während der Schulschließung. Die Daten bestätigen den „digital divide“ in den Kompetenzen und Erfahrungen der Lehrkräfte. Lehrkräfte in Österreich und der Schweiz schätzen ihre digitalen Kompetenzen höher ein als deutsche Mitarbeitende. Die technische Ausstattung wird von Befragten aus Österreich und der Schweiz ebenfalls besser eingeschätzt als in Deutschland. Die Kooperation zwischen Mitarbeitenden der Schule selbst sowie mit Eltern und ein stärkerer Fokus auf die Beziehungsebene zu Schüler*innen wird in Zeiten der Krise trotz und wegen der Distanz noch bedeutsamer für Lehre und Lernen. Perspektivisch können aus den Daten des Schul-Barometers Empfehlungen für die „Schule von morgen“ abgeleitet werden.

description: Die Ausbreitung der COVID-19-Pandemie hat in Nordrhein-Westfalen am 16.03.2020 zu allgemeinen Schulschließungen geführt. Von einem Tag auf den nächsten waren die Lehrkräfte gefordert, ihre Kommunikation mit den Schüler*innen und ihre Lernunterstützung auf Distanz auszuüben. Die Eltern sahen sich gleichzeitig vor der Herausforderung, ihre Kinder ganztägig zu Hause zu betreuen und beim Lernen zu unterstützen. Die Begriffe Distance Learning und Homeschooling fanden schnell Einzug in den allgemeinen Sprachgebrauch. In diesem Beitrag werden Ergebnisse einer qualitativen Befragung vorgestellt, in der rund drei Wochen nach den Schulschließungen sowohl Eltern als auch Lehrkräfte einer Schule zu ihren Erfahrungen mit den verschiedenen Aufgaben der ersten Wochen befragt wurden. Ein Fokus wurde dabei auf den Einsatz von digitalen Medien und Konzepten als Instrumenten von Kommunikation und Lernunterstützung auf Distanz gelegt. Beleuchtet wird, welche Aspekte der vielschichtigen Herausforderungen von den beiden Akteursgruppen Eltern und Lehrkräfte thematisiert werden und wie der eigene Umgang mit diesen Herausforderungen dargestellt wird.

description: Based on the Mie theory and on the incident beam model via superposition of two plane waves, we analyze numerically the momentum flux of the field scattered by a spherical microparticle placed within the spatially inhomogeneous circularly polarized paraxial light beam. The asymmetry between the forward- and backward-scattered momentum fluxes in the Rayleigh scattering regime appears due to the spin part of the internal energy flow in the incident beam. The transverse ponderomotive forces exerted on dielectric and conducting particles of different sizes are calculated and special features of the mechanical actions produced by the spin and orbital parts of the internal energy flow are recognized. In particular, the transverse orbital flow exerts the transverse force that grows as a^3 for conducting and as a^6 for dielectric subwavelength particle with radius a, in compliance with the dipole mechanism of the field-particle interaction; the force associated with the spin flow behaves as a^8 in both cases, which testifies for the non-dipole mechanism. The results can be used for experimental identification and separate investigation of the spin and orbital parts of the internal energy flow in light fields.

description: While Generative Adversarial Networks (GANs) show increasing performance and the level of realism is becoming indistinguishable from natural images, this also comes with high demands on data and computation. We show that state-of-the-art GAN models -- such as they are being publicly released by researchers and industry -- can be used for a range of applications beyond unconditional image generation. We achieve this by an iterative scheme that also allows gaining control over the image generation process despite the highly non-linear latent spaces of the latest GAN models. We demonstrate that this opens up the possibility to re-use state-of-the-art, difficult to train, pre-trained GANs with a high level of control even if only black-box access is granted. Our work also raises concerns and awareness that the use cases of a published GAN model may well reach beyond the creators' intention, which needs to be taken into account before a full public release.
Deciphering mantle source components in basalts from hotspot tracks and oceanic islands

description: The isotopic compositions of oceanic island basalts erupted at the Earth’s surface can be used to directly constrain the isotopic signatures of their deep mantle sources. Basaltic rocks are highly susceptible to seawater alteration, which can significantly modify elemental contents and potentially hinder the use of radiogenic isotopes as geochemical tracers. In this study, multi-isotopic (e.g., Pb-Hf-Sr-Nd) analyses on the same acid-leached sample aliquot are shown to produce reliable results for use in the discrimination of mantle source components of oceanic basalts. Application to basalts from the Ninetyeast Ridge in the Indian Ocean and from Mauna Kea volcano on Hawaii in the Pacific Ocean allows for an enhanced resolution of their source components and distribution in the deep mantle. Isotopic geochemistry of the Ninetyeast Ridge sampled during Ocean Drilling Project Leg 121 reveals a Kerguelen and Amsterdam-St. Paul mantle plume origin with the presence of at least three source components and no contribution from an Indian mid-ocean ridge basalt source. The isotopic characteristics of the Ninetyeast Ridge basalts are typical of the Dupal isotopic domain and consistent with recycling of altered oceanic crust and a mixture of pelagic sediments and lower continental crust into their mantle source. This supports a deep origin for the enriched mantle “EM-1”-like Dupal signatures encountered in Indian Ocean island basalts. In the Pacific Ocean, isotopic heterogeneity in basalts from the deepest parts of the Hawai’i Scientific Drilling Project (HSDP2) core on Mauna Kea, combined with prior results from overlying flows, indicate that shield basalts can be explained by mixing of variable proportions of four isotopically distinct components intrinsic to the Hawaiian mantle plume. The “Kea” component is the prevailing composition in Mauna Kea basalts and throughout volcanic activity of the Hawaiian hotspot. The relatively depleted isotopic compositions of this “Kea” component are shared by other Pacific oceanic island basalt groups and are very similar to those of the common mantle component “C”. This suggests that “Kea” may be a common and widespread composition within the deep mantle beneath the Pacific Ocean basin.

description: Die Corona-Pandemie führt zu zahlreichen Herausforderungen für Lehrkräfte und Schüler*innen. Die meist digital aufbereiteten Lernmaterialien sollten vor allem während des Lockdowns nur wenig Unterstützung seitens der Lehrkräfte erfordern und die Schüler*innen größtenteils zum selbstständigen Arbeiten befähigen. Dies bedeutete daher für die Lehrkräfte, möglichst binnendifferenzierendes Material zu entwickeln und digital umzusetzen, was z.T. ganz neue Ansätze erforderte. Auch für Eltern ergab sich durch das Homeschooling eine neue Situation, da sie die Rolle der Lehrkräfte zumindest in Teilen mitübernehmen und ihre Kinder beim Lernen zu Hause unterstützen müssen. In diesem Kontext ist davon auszugehen, dass Eltern durch diese zusätzliche Aufgabe neben ihrer eigenen Berufstätigkeit sowie angesichts nicht immer passgenauer Lernmaterialien für ihre Kinder eine Mehrbelastung erfahren. Dieser Beitrag geht der Thematik des Homeschoolings und der digital zur Verfügung gestellten Materialien nach und greift auf Ergebnisse einer Onlinebefragung von 635 Eltern in Rheinland-Pfalz zurück, die während der Schulschließung durchgeführt wurde. Dabei wird zum einen untersucht, wie das Belastungsempfinden der Eltern in dieser Zeit ausgeprägt ist und welche individuellen Faktoren dieses beeinflussen. Zum anderen wird analysiert, wie das Belastungsempfinden mit der Qualität der bereitgestellten Materialien und der eingeschätzten Medienkompetenz der Lehrkräfte zusammenhängt. Es zeigt sich, dass das Belastungserleben neben persönlichen Unterschieden auch durch die Gestaltung des Lehrmaterials beeinflusst wird.
