Vermittlung von Kompetenzen im Bereich der Medienkritik – ein unterschätzter Faktor in der schulischen Medienerziehung?
Creators: name: Gabriel, Sonja
Publisher: name: Medienimpulse
Year: 2017

description: Medienkritik und damit die Analyse-, Reflexions- und Urteilsfähigkeit gewinnen in der digitalisierten Welt immer stärker an Bedeutung. In den vergangenen Jahren wird der Ruf – auch in der Digitalisierungsstrategie "Schule 4.0" des Bundsministeriums für Bildung – nach Schulung ebendieser Kompetenz immer lauter. Am Beispiel der Flüchtlingssituation im deutschsprachigen Raum zeigt sich, dass die Zahl der Hoaxes steigt und dass viele User diese Berichte für wahr halten. Verschiedene Studien zeigen auf, dass Jugendliche häufig nicht in der Lage sind zu erkennen, was als seriöse und glaubwürdige Information gelten kann und was so genannte Fake-News sind. Gerade der Bereich der Medienkritik wird aber häufig in der schulischen Vermittlung digitaler Kompetenz ausgeklammert.

description: (abridged) We study a previously discovered protostellar source that is deeply embedded and drives an energetic molecular outflow. The source, UYSO1, is located close to IRAS 07029-1215 at a distance of ~1 kpc. The multi-wavelength observations resulted in the detection of a double intermediate-mass protostar at the location of UYSO1. In addition to the associated molecular outflow, with a projected size of 0.25 pc, two intersecting near-infrared jets with projected sizes of 0.4 pc and 0.2 pc were found. However, no infrared counterparts to the driving sources could be detected in sensitive near- to far-infrared observations. In interferometric millimeter observations, UYSO1 was resolved into two continuum sources with high column densities and gas masses of 3.5 Mo and 1.2 Mo, with a linear separation of 4200 AU. We report the discovery of a H2O maser toward one of the two sources. The total luminosity is roughly estimated to be ~50 Lo, shared by the two components, one of which is driving the molecular outflow that has a dynamical timescale of less than a few thousand years. The jets of the two individual components are not aligned. Submillimeter observations show that the region lacks typical hot-core chemistry. We thus find two protostellar objects, whose associated circumstellar and parent core masses are high enough to suggest that they may evolve into intermediate-mass stars. This is corroborated by their association with a very massive and energetic CO outflow, suggesting high protostellar accretion rates. The short dynamical timescale of the outflow, the pristine chemical composition of the cloud core and absence of hot core tracers, the absence of detectable radio continuum emission, and the very low protostellar luminosity argue for an extremely early evolutionary stage.

description: We present the Green-Schwarz action for Type IIA strings on $AdS_4\times CP^3$. The action is based on a $\Zop_4$ automorphism of the coset $OSp(4|6)/(SO(1,3)\times SU(3)\times U(1))$. The equations of motion admit a representation in terms of a Lax connection, showing that the system is classically integrable.

Homage to Schoenberg and Bartók: Symmetry, Transpositional Combination and Octatonicism in the First Movement of Roberto Gerhard's Quartetto No. 3

Publisher: name: Humboldt-Universität zu Berlin
Year: 2020
Subjects: subject: 780 Musik

description: The first movement of Roberto Gerhard's Quartetto No. 3 (ca. 1927), his final assignment under Schoenberg, represents a direct homage to the teacher. Gerhard finished the movement with a clearly identifiable allusion to the minor and major chords that close Schoenberg's String Quartet in F♯ minor No. 2, Op. 10 (1907–8). Furthermore, he employed the four-note set resulting from the fusion of these chords (pc set 4–17) as the movement's generative idea, expanding its main structural properties, namely inversional symmetry and transpositional combination, to inform the movement's large-scale sonata layout and a number of configurations of key structural importance throughout the movement. In the development, he elaborated Schoenberg's materials by implementing a technique used extensively by Bartók at the time, namely the combination of dyads with one or more transpositions of themselves for generating larger (often octatonic) structures. Gerhard's compositional method in the movement shows not only the decisive impact of Schoenberg's principles but also his indebtedness to the music of Bartók, to whom the composition seems to pay tribute as equally as to Schoenberg. This article utilises these perspectives to offer an analysis of the first movement of Gerhard's Quartetto No. 3/Concertino.

description: The branching fraction of the decay $τ\to K^{-} ην_τ$ has been calculated by using the extended Nambu-Jona-Lasinio model taking into account the meson interaction in the final state. The contact term and the channel with the intermediate ground $K^{*}(892)$ and first radially excited state $K^{*}(1410)$ have been calculated. For the purpose of describing the meson interaction in the final state, the triangle diagram with three mesons has been considered. The cutoff parameter of divergent integrals of the meson loop is equal to the appropriate parameter used in our previous work to describe the decay $τ\to K^{-} π^{0} ν_τ$. Thereby, the present work does not set any additional arbitrary parameters. The obtained results are in satisfactory agreement with the experimental data.

description: Die Vorstellung unterschiedlicher Möglichkeiten des Einsatzes von digitalen Spielen für soziale Inklusion bildet den Fokus dieses Artikels. In dem Zusammenhang wird beschrieben, was soziale Inklusion ist und das Potenzial von digitalen Spielen für soziale Inklusion umrissen. Anschließend werden erprobte Unterrichtsszenarien vorgestellt. Diese setzen sich zusammen aus, dem Setting, dem Ablauf und den zentralen Elementen der Szenarien sowie digitalen Spielen und spielbasierter Dialoge. Es wird gezeigt, wie sich Spiele und spielbasierte Dialoge kombinieren lassen und welche didaktischen Verläufe im Unterricht einsetzbar sind. Abschließend werden erste Forschungsergebnisse zum Einsatz von digitalen Spielen für soziale Inklusion diskutiert. Die Erprobung der inklusiven Unterrichtsszenarien hat gezeigt, dass der Einsatz von Spielen in Kombination mit spielbasierten Dialogen einen wichtigen Anstoß für die Thematisierung von zentralen Problemlagen gibt bzw. geben kann. Gleichzeitig hilft das Herstellen einer spielerischen und angenehmen Atmosphäre, frei über die Auswirkungen von Krisen auf die persönliche Lebenswelt sowie den Schulalltag zu sprechen. Spiele bieten dabei einen Anlass, bestehende Konflikte in der Klasse sichtbar zu machen. Gleichzeitig kann dadurch sichergestellt werden, dass eine handhabbare Eskalationsstufe nicht überschritten wird. Spielbasierte Dialoge sind dabei ein unverzichtbarer Bestandteil von inklusiven Unterrichtsszenarien, weil in dieser Phase zentrale Emotionen, Problemlagen, Bedürfnisse und Konflikte, die in den Spieleinheiten aufgekommen sind, thematisiert und ggf. aufgelöst werden können. Gleichzeitig bieten die spielbasierten Dialoge einen Anlass, die spielerische und lustvolle Atmosphäre in der gemeinsamen Diskussion weiterzuführen und weiterhin Freude aneinander zu haben.

description: Eigenvalues of a Wilson loop operator are gauge invariant and their distribution undergoes a transition at infinite N as the size of the loop is changed. We study this transition using the average characteristic polynomial associated with the Wilson loop operator. We derive the scaling function in a certain double scaling limit for two dimensional QCD and hypothesize that the transition in three and four dimensional QCD are in the same universality class. Numerical evidence for this hypothesisis provided in three dimensions

description: Recommender systems play an important role in supporting the achievement of the United Nations sustainable development goals (SDGs). In recommender systems, explanations can support different goals, such as increasing a user's trust in a recommendation, persuading a user to purchase specific items, or increasing the understanding of the reasons behind a recommendation. In this paper, we discuss the concept of "sustainability-aware persuasive explanations" which we regard as a major concept to support the achievement of the mentioned SDGs. Such explanations are orthogonal to most existing explanation approaches since they focus on a "less is more" principle, which per se is not included in existing e-commerce platforms. Based on a user study in three item domains, we analyze the potential impacts of sustainability-aware persuasive explanations. The study results are promising regarding user acceptance and the potential impacts of such explanations.

Free versus Bound Entanglement: Machine learning tackling a NP-hard problem
Creators: name: Hiesmayr, Beatrix C.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Entanglement detection in high dimensional systems is a NP-hard problem since it is lacking an efficient way. Given a bipartite quantum state of interest free entanglement can be detected efficiently by the PPT-criterion (Peres-Horodecki criterion), in contrast to detecting bound entanglement, i.e. a curious form of entanglement that can also not be distilled into maximally (free) entangled states. Only a few bound entangled states have been found, typically by constructing dedicated entanglement witnesses, so naturally the question arises how large is the volume of those states. We define a large family of magically symmetric states of bipartite qutrits for which we find $82\%$ to be free entangled, $2\%$ to be certainly separable and as much as $10\%$ to be bound entangled, which shows that this kind of entanglement is not rare. Via various machine learning algorithms we can confirm that the remaining $6\%$ of states are more likely to belonging to the set of separable states than bound entangled states. Most important we find via dimension reduction algorithms that there is a strong $2$-dimensional (linear) sub-structure in the set of bound entangled states. This revealed structure opens a novel path to find and characterize bound entanglement towards solving the long-standing problem of what the existence of bound entanglement is implying.

description: Fermentology is a series of mini-lectures led by leading scientists, authors, and researchers -- all focusing on the history and science of the foods we have at home. While the original modality of Fermentology existed through shareable videos, now we strive to increase the accessibility and readability of these mini-lectures by constructing enriched versions of these talks. The enriched talks begin with transcripts from the Fermentology webinars and are then threaded with media, interactive elements, and links to other resources, morphing from a video lecture to a web-primary text for increased longevity, accessibility, and engagement. The goal was to extend and enhance the lectures, invite interested viewers to become readers, and engage participants in the ideas presented -- prioritizing communicated scholarship as a process for “modulating, re-presenting, and then amplifying academic knowledge in non-academic modes” (Vandegrift, 2021). We see this knowledge mobilization and sharing as an experimental form of open publishing, something in the middle of journalism, archival research, digital and public scholarship.

A survey of zoospore and sperm ultrastructure in the Laminariales (Phaeophyceae)
Creators: name: Henry, Eric Charles
Publisher: name: University of British Columbia
Year: 2010

description: Zoospores of 17 species in 14 genera and sperm of 13 species in 11 genera of Laminariales were studied by electron microscopy. The zoospores are unique in the brown algae in lacking both an eyespot in the single chloroplast and an associated swelling at the base of the shorter, posterior flagellum. Spores of all species possess a distal whiplash on the longer, mastigoneme-bearing anterior flagellum; although it is only seldom preserved for electron microscopy, this appendage may sometimes be as long as the mastigoneme-bearing portion of the flagellum. A microtubular cytoskeleton with connections to the flagellar basal bodies is responsible for maintaining the shape of the zoospore. The sperm are also unique in the brown algae. They are elongate and possess two to three plastids and several mitochondria, but lack an eyespot. Their most distinctive feature is the long posterior flagellum which tapers distaliy as the doublet microtubules of the axoneme are transformed into singlets and then decrease in number. The sperm also bear a distal whiplash on the mastigoneme-bearing anterior flagellum. These laminarialean zoospores and sperm are ultrastructurally distinct from those known in other orders of brown algae, and from Chorda of the Laminariales, which confirms that Chorda is primitive. The longer posterior flageilum of the sperm recalls similar modifications in sperm of other oogamous brown algae, and suggests a common functional significance.

description: The non-thermal acceleration of electrons and ions at an oblique, non-relativistic shock is studied using large scale particle-in-cell (PIC) simulations in one spatial dimension. Physical parameters are selected to highlight the role of electron pre-heating in injection and subsequent acceleration of particles at high Mach number shocks. Simulation results show evidence for the early onset of the diffusive shock acceleration process for both electrons and ions at a highly oblique subluminal shock. Ion acceleration efficiencies of $\lesssim 5\%$ are measured at late times, though this is not the saturated value.

Doping-controlled surface conduction in topological insulators with warping effects

description: Based on a self-consistent $t$-matrix approximation, we explore the influence of magnetic and nonmagnetic doping on the surface electronic states and conductivity of topological insulators. We show that warping parameter has a crucial impact on the density of states and dc conductivity of the doped surfaces. As the warping strength is increased, the surface density of states at high energies is suppressed and the resonant states induced by impurities in the vicinity of the Dirac point gradually disappear. It is found that nonmagnetic impurities break electron-hole symmetry at low warping strength, while the symmetry remains unchanged when the surface is magnetically doped. Our findings reveal that surface conductivity can be controlled by tuning the doping, the direction of external magnetic field and that of impurity magnetic moments. Also, the surface conductivity features in topological insulators with warped energy dispersions are not significantly affected by the presence of impurities compared to that of materials with circular energy contour.

description: Katharina Sontags Beitrag setzt mit Bernd Schorbs Erkenntnis ein, dass es angesichts der mediatisierten Wissens- und Informationsgesellschaft nicht mehr nur um die Rezeption von medialen Inhalten geht, sondern auch um deren aktive Nutzung, weshalb schon aus diesem Grund die Option für eine handlungsorientierte bzw. praxeologische Medienpädagogik nahe liegt. Dabei geht es neben der partizipatorischen Einbeziehung der SchülerInnen auch und vor allem um ihr selbständiges und verantwortliches Handeln. Im Sinne Dieter Baackes werden dabei die Lebenswelten der Lernenden nachdrücklich als Medienwelten begriffen. Die aktive und produktive Nutzung der Medien stellt insofern einen ganzheitlichen Prozess der Weltaneignung dar, die auch im Blick auf eine demokratische Mediengesellschaft von großer Bedeutung ist.

description: The travel marketing platform of Alibaba serves an indispensable role for hundreds of different travel scenarios from Fliggy, Taobao, Alipay apps, etc. To provide personalized recommendation service for users visiting different scenarios, there are two critical issues to be carefully addressed. First, since the traffic characteristics of different scenarios, it is very challenging to train a unified model to serve all. Second, during the promotion period, the exposure of some specific items will be re-weighted due to manual intervention, resulting in biased logs, which will degrade the ranking model trained using these biased data. In this paper, we propose a novel Scenario-Aware Ranking Network (SAR-Net) to address these issues. SAR-Net harvests the abundant data from different scenarios by learning users' cross-scenario interests via two specific attention modules, which leverage the scenario features and item features to modulate the user behavior features, respectively. Then, taking the encoded features of previous module as input, a scenario-specific linear transformation layer is adopted to further extract scenario-specific features, followed by two groups of debias expert networks, i.e., scenario-specific experts and scenario-shared experts. They output intermediate results independently, which are further fused into the final result by a multi-scenario gating module. In addition, to mitigate the data fairness issue caused by manual intervention, we propose the concept of Fairness Coefficient (FC) to measures the importance of individual sample and use it to reweigh the prediction in the debias expert networks. Experiments on an offline dataset covering over 80 million users and 1.55 million travel items and an online A/B test demonstrate the effectiveness of our SAR-Net and its superiority over state-of-the-art methods.

description: Der Umgang mit digitalen Medien gilt mit steigender Relevanz als zentrale Schlüsselkompetenz für Heranwachsende im 21. Jahrhundert (Eickelmann/Bos 2011; Herzig 2010). Studien haben allerdings Unterschiede hinsichtlich der Verfügbarkeit digitaler Medien zugunsten ökonomisch privilegierter Familien von Kindern und Jugendlichen identifiziert (z.B. OECD 2006; Spiezia 2010). Inwieweit sich dieser Zusammenhang vor dem Hintergrund der ökonomischen Schülerkomposition von Schulen und u.a. in deren technologischer Ausstattung zeigt (Eickelmann 2010; Eickelmann/Schulz-Zander 2008, 2010; Schulz-Zander/Eickelmann/Goy 2010), ist Gegenstand des Beitrags. Mit einem auf den Primarbereich gerichteten Fokus, werden die Schuldaten von IGLU (Internationale Grundschul-Lese-Untersuchung)/PIRLS (Progress in International Reading Literacy Study) 2011 herangezogen, um so mit einer repräsentativen Stichprobe deskriptiv den Zusammenhang der schulischen Ausstattung mit der ökonomischen Lage der SchülerInnenschaft zu erörtern. Dazu werden die Analyseergebnisse von Österreich und Deutschland miteinander verglichen und im internationalen Vergleich diskutiert, wobei ein Hauptaugenmerk auf Teilnehmerstaaten der EU gelegt wird.

description: Im Advent 2015 veröffentlichte die Evangelische Stadtmission Freiburg e.V. in ihrer Zeitschrift „Von Wegen : leben. glauben. handeln.“ (Ausgabe 4/2015) das vorliegende Interview mit Andreas Mähler.

Demnach erleben verurteilte Straftäter das Warten anders als Untersuchungshäftlinge, die oft in großer Ungewissheit auf ihren Prozess und das Strafurteil warten. Falls es zu einer Verurteilung mit einer langen Haftdauer kommt, bricht „das Leben draußen oft komplett weg.“

Mähler beschreibt einerseits Konfliktpotenziale und Rückfallgefahren und andererseits Entwicklungschancen der Haftzeit. Dennoch macht es einen großen Unterschied, „ob man sich im Advent aus religiöser Haltung und Tradition bewusst in den Zustand des Wartens begibt oder ob man dazu durch ein Gerichtsurteil gezwungen wird.“

description: H13 die steel, valued for its hardenability, high-temperature strength, and toughness, is extensively utilized in aerospace and automotive industries. However, electrical discharge machining (EDM) induces surface defects like recast layers, heat-affected zones, and debris globules, contributing to mold failures. This study examines H13 steel surfaces processed via ultrasonic-assisted mixed powder EDM using four working fluids with varying Al₂O₃ and diamond particle concentrations. COMSOL simulations based on Blake’s theory confirmed significant cavitation in the processing slit. SEM analysis revealed distinct surface morphologies, linking variations in debris globules, cracks, and discharge craters to particle properties. Results indicate that ultrasonic cavitation and particle characteristics (thermal conductivity, specific surface area) critically influence energy dissipation and surface morphology. Adjusting particle concentration effectively optimizes surface quality, demonstrating that particle selection and concentration control are key to enhancing EDM-processed workpiece performance.
(Medien)bildung und Informatik

description: Niemand kann die Wichtigkeit der Informatik für unsere Welt abstreiten. Fast jeder Aspekt unseres Lebens steht in einer bestimmten Art in Verbindung mit Software. Es ist daher logisch anzunehmen, dass Kinder die Fähigkeit benötigen die Technik, die sie verwenden, zu verstehen und diese auch kritisch zu betrachten. Dieser Umstand macht Informatik zu einem wichtigen Teilaspekt der Medienbildung. Weiterhin erweitern die Fortschritte aus der Computerentwicklung unsere Fähigkeit Probleme zu lösen in einer bisher unbekannten Dimension. SchülerInnen werden neue Fähigkeiten lernen und einüben müssen (Computational Thinking) um diese revolutionären Veränderungen, die der technische Fortschritt mit sich bringt, auszunutzen. Die Schlüsselfrage wird dabei sein, welchen Ansatz man wählen wird, um diese Fähigkeiten auszubilden und welche politischen Beweggründe dahinterstehen. Die aktuelle politische Lage zeigt eine wirtschaftliche Orientierung, die ähnlich ist zur Stärkung der MINT-Fächer vor einigen Jahren, welche ebenfalls von der Wirtschaft gefordert wurde. Bildung muss jedoch mehr sein als die Erfüllung von aus der Wirtschaft stammenden Wünschen.

description: We propose a mechanism that incorporates network coding into TCP with only minor changes to the protocol stack, thereby allowing incremental deployment. In our scheme, the source transmits random linear combinations of packets currently in the congestion window. At the heart of our scheme is a new interpretation of ACKs - the sink acknowledges every degree of freedom (i.e., a linear combination that reveals one unit of new information) even if it does not reveal an original packet immediately. Such ACKs enable a TCP-like sliding-window approach to network coding. Our scheme has the nice property that packet losses are essentially masked from the congestion control algorithm. Our algorithm therefore reacts to packet drops in a smooth manner, resulting in a novel and effective approach for congestion control over networks involving lossy links such as wireless links. Our experiments show that our algorithm achieves higher throughput compared to TCP in the presence of lossy wireless links. We also establish the soundness and fairness properties of our algorithm.

description: Complex treatment of generalized periodontitis, the special attention paid by the appropriate combination of conservative and surgical treatment methods, significantly increases the destructive process of the connective tissue and restoring the amount of available data[1-9]. However, despite the variety of facts and developments, conservative and surgical interventions on the nexus alone cannot clearly read the disease process and sufficient condition of the gum tissue regeneration[10-18]. Cases, the use of new technologies, including the use of medical rehabilitation, medical wipes and other conservative treatment, did not lead or the underlying mechanism of the inflammatory process, and case affect its further destruction. Consultation with stakeholders lesions 2-3 degrees of severity, the bones of an existing connection. Commission staff working different items of the truth, there no real medical research hospital with symptoms of the disease, which created a course solve the protein content of conservative treatment and the active process of destruction of abnormal bone tissue.
Unemployment insurance and the distribution of workers between labour force states

description: In this study, I examine the influence of unemployment insurance benefits on labour force participation, employment, and unemployment. Conclusions are developed concerning the consequences of the 1971 revision of the Canadian unemployment insurance programme, which differ from those of earlier writings in this field. My model estimates the proportions of the population in each labour force state (employment, unemployment, and "not in the labour force"). Each labour force state proportion is modelled as a function of the gross flows between the labour force states. This model resembles a Markov model and is similar to the model developed by Toikka (197 6). The decisions by employers and employees that generate the gross flows between labour force states are modelled as behavioural functions of economic variables. Unlike other studies, this study imposes strict consistency between equations due to the conservation of the population in the gross flows. Other studies have tended to be single equation models and the specification of the equations between studies and in one case, within a study, is not consistent. The model is estimated for ten age-sex populations. It is estimated using monthly' data for the period 1961 to 1975. The estimation method is Full Information Maximum Likelihood. Because the system of three equations is singular, one equation is redundant and may be dropped during estimation. Estimation is independent of which equation is dropped. This study brings evidence to support the position that different groups respond in different ways to changes in unemployment insurance. According to the model, prime age men are unresponsive to short-term fluctuations in incentives. Young and old men appear to reduce their labour supply when unemployment insurance benefits are increased. This is the net effect of changes in the gross flows between labour force states. The model suggests that the net labour force participation of women increases in response to increases in unemployment Insurance benefits. Men and women differ in their response to unemployment insurance in two additional ways. First estimated responses for women are generally greater than those for men. While women respond seasonally and non-seasonally to unemployment insurance, the response by men tends to be restricted to seasonal behaviour. These findings are consistent with earlier findings in that they suggest a general increase in unemployment and labour force participation due to increases In unemployment insurance. Although my findings suggest some unemployment insurance—induced quit behaviour, they do not suggest a decline in the aggregate level of employment. The dominant result in this study is that unemployment insurance Induces labour force participation, which places upward pressure on employment and unemployment.

description: We study the properties of a system consisting of an uncharged spherically symmetric two dimensional extended object which encloses a stationary point charge placed in the shell's center. We show that there can be a static and stable configuration for the neutral shell, using only the gravitational field of the charged source as a stabilizing mechanism. In particular, two types of shells are studied: a dust shell and a string gas shell. The dynamical possibilities are also analyzed, including the possibility of child universe creation.

Diagnosis and Fault detection in Electrical Machines and Drives based on Advanced Signal Processing Techniques

description: In the present thesis, a new methodology of diagnosis based on advanced use of time-frequency technique analysis is presented. More precisely, a new fault index that allows tracking individual fault components in a single frequency band is defined. More in detail, a frequency sliding is applied to the signals being analyzed (currents, voltages, vibration signals), so that each single fault frequency component is shifted into a preﬁxed single frequency band. Then, the discrete Wavelet Transform is applied to the resulting signal to extract the fault signature in the frequency band that has been chosen. Once the state of the machine has been qualitatively diagnosed, a quantitative evaluation of the fault degree is necessary. For this purpose, a fault index based on the energy calculation of approximation and/or detail signals resulting from wavelet decomposition has been introduced to quantify the fault extend. The main advantages of the developed new method over existing Diagnosis techniques are the following:
-	Capability of monitoring the fault evolution continuously over time under any transient operating condition;
-	Speed/slip measurement or estimation is not required;
-	Higher accuracy in filtering frequency components around the fundamental in case of rotor faults;
-	Reduction in the likelihood of false indications by avoiding confusion with other fault harmonics (the contribution of the most relevant fault frequency components under speed-varying conditions are clamped in a single frequency band);
-	Low memory requirement due to low sampling frequency;
-	Reduction in the latency of time processing (no requirement of repeated sampling operation).
