Daran anschließend wird die Bedeutung lernunterstützender Maßnahmen in einem solchen digital gestützten und potenziell kreativitätsfördernden Unterrichtssetting erläutert (Kapitel 2). In Kapitel 3 folgt die Vorstellung der Unterrichtsreihe „It’s storytime – Let’s create our own digital fairy tale“. Im Verlauf dieser Unterrichtsreihe, die auch als Projektwoche angelegt werden kann, rezipieren die Schüler:innen zunächst eigenständig Märchen in englischer Sprache, die aus dem deutschen und angloamerikanischen Sprachraum bekannt sind. Die Märchen liegen für das Tablet multimedial aufbereitet vor. Anschließend entwickeln die Lernenden auf Grundlage des erarbeiteten gattungsspezifischen Wortschatzes ein eigenes multimediales Märchen. Alle für die Unterrichtsreihe benötigten digitalen und analogen Materialien stehen als Download zur Verfügung und können für den eigenen Unterricht genutzt und adaptiert werden.

T1 - Unilateral Environmental Policy and Offshoring N2 - Expanding on a general equilibrium model of offshoring, we analyze the effects of a unilateral emissions tax increase on the environment, income, and inequality. Heterogeneous firms allocate labor across production tasks and emissions abatement, while only the most productive can benefit from lower labor and/or emissions costs abroad and offshore. We find a non-monotonic effect on global emissions, which decline if the initial difference in emissions taxes is small. For a sufficiently large difference, global emissions rise, implying emissions leakage of more than 100%. The underlying driver is a global technique effect: While the emissions intensity of incumbent non-offshoring firms declines, the cleanest firms start offshoring. Moreover, offshoring firms become dirtier, induced by a reduction in the foreign effective emissions tax in general equilibrium. Implementing a BCA prevents emissions leakage, reduces income inequality in the reforming country, but raises inequality across countries. T3 - Würzburg Economic Papers (W. E.

One way to ensure the reliability of a data transmission is to use multiple transmission technologies in combination with redundant flows. In this paper, we describe a system requiring multipath communication in the context of CCAM. To this end, we introduce a data plane-based scheduler that uses replication and integration modules to provide redundant and transparent multipath communication. We provide an analytical model for the full replication module of the system and give an overview of how and where the data-plane scheduler components can be realized.

Die mainEUropa-Blogs wollten über ausgewählte Aspekte der EU-Politik aktuell, knapp und leicht verständlich informieren; damit haben sie dem EU-Geschehen der Jahre 2017 bis 2021 aus jeweils aktuellen Anlässen den Puls genommen und zu einem besseren Verständnis der EU-Politik- und Entscheidungsprozesse beigetragen. Die Blog-Themen sind breit gefächert und bilden somit ausgewählte Ereignisse und Weichenstellungen aus der jüngeren Integrationsgeschichte ab. Die Themen reichen über klimapolitische Beschlüsse, das Ringen um den Erhalt bzw. die Wiederherstellung der Rechtstaatlichkeit in einigen EU-Mitgliedstaaten, das Endlos-Drama des Brexits, wichtige Wahlen in der EU und ausgewählten Mitgliedstaaten bis hin zu neuen Entwicklungen in der EU-Außen-, Sicherheits- und Verteidigungspolitik sowie zu den überraschend zupackenden Antworten der EU auf die Covid-19-Pandemie. Ein Blick auf die europapolitische Agenda der im Dezember 2021 angetretenen rot-grün-gelben Ampel-Bundesregierung beschließt die Reihe. Denn 2021 endete auch das die mainEUropa-Blogs tragende Jean Monnet Projekt, so dass das vorliegende fünfte Jean Monnet Paper auch das letzte sein wird.

T1 - Are Biases Contagious? The Influence of Communication on Motivated Beliefs N2 - This paper examines the potential reinforcement of motivated beliefs when individuals with identical biases communicate. We propose a controlled online experiment that allows to manipulate belief biases and the communication environment. We find that communication, even among like-minded individuals, diminishes motivated beliefs if it takes place in an environment without previously declared external opinions. In the presence of external plural opinions, however, communication does not reduce but rather aggravates motivated beliefs. Our results indicate a potential drawback of the plurality of opinions - it may create communication environments wherein motivated beliefs not only persist but also become contagious within social networks.

We show that the persistent current value trade imbalance patterns contribute to a higher level of global emissions compared to a world of balanced international trade. Specifically, we build a Ricardian quantitative trade model including sectoral input-output linkages, trade imbalances, fossil fuel extraction, and carbon emissions from fossil fuel combustion and use this framework to simulate counterfactual changes to countries' trade balances. For individual countries, the emission effects of removing their trade imbalances depend on the carbon intensities of their production and consumption patterns, as well as on their fossil resource abundance. Eliminating the Russian trade surplus and the US trade deficit would lead to the largest environmental benefits in terms of lower global emissions. Globally, the simultaneous removal of all trade imbalances would lower world carbon emissions by 0.9 percent or 295 million tons of carbon dioxide. T3 - Würzburg Economic Papers (W. E.

Due to high uncertainty about relevant determinants, trend patterns and the correct estimation method, we propose in this paper a simple alternative approach derived from a standard macro model. Starting from a loss function, neutral periods can be determined in which a neutral real interest rate is observable. Using these values, a medium-term trend for a neutral interest rate can be determined. An application to the USA shows that our simple calculation of a neutral interest rate delivers comparable results to existing studies. A Taylor rule based on our neutral interest rate also does a fairly good job of explaining US monetary policy over the past 60 years. T3 - Würzburg Economic Papers (W. E.

Due to competitive price determination and supposedly higher efficiency, auctions have in recent years widely succeeded feed-in-tariffs as the primary support instrument (del Rio & Linares, 2014; REN21, 2021). However, literature still struggles to produce causal evidence to validate mostly descriptive findings for efficiency gains. Yet, this evidence is needed as a foundation to provide robust recommendations to policy makers (Grashof et al., 2020). By utilizing a difference-in-differences approach, this paper provides such evidence for a German photovoltaic (PV) auctioning program which came into effect in 2015. Results for this natural experiment confirm that cost-effectiveness improved significantly while previous literature shows that capacity expansion remained high. Results additionally show that falling prices for PV panels were the primary driver of cost reductions and wages also exert high influence on support price. Input cost development therefore indeed strongly influences support level which was the aim with introducing competitive auctions. Interest rate development cannot be linked to support level development, most probably due to the low interest environment in considered period. T3 - Würzburg Economic Papers (W. E.

Eliciting subjects’ receptiveness to rightwing populism and their perceived relative income positions in a representative survey of German households, we find that people with pessimistic beliefs about their income position are more attuned to populist statements. Key to understanding the misperception-populism relationship are strong gender differences in the mechanism: men are much more likely to channel their discontent into affection for populist ideas. A simple information provision does neither sustainably reduce misperception nor curb populism. T3 - Würzburg Economic Papers (W. E.

Of course, virtualization provides a base level of abstraction for services to be deployable on a lot of infrastructures. With container virtualization, the trend to migrate applications to a micro-services level in order to be executable in Fog and Edge Computing environments increases manageability and maintenance efforts rapidly. Similarly, network virtualization adds effort to calibrate IP flows for Software-Defined Networks and eventually route it by means of Network Function Virtualization. Nevertheless, there are concepts like MAPE-K to support micro-service distribution in next-generation cloud and network environments. We want to explore, how a service distribution can be improved by adopting machine learning concepts for infrastructure or service changes. Therefore, we show how federated machine learning is integrated into a cloud-to-fog-continuum without burdening single nodes.

Infrastructures are cumbersome to set up or are not available due to vendor-specific devices. Emulators try to overcome those issues to a given extent and are available in different service models. Unfortunately, the usability of emulators requires time-consuming efforts and a deep understanding of their functionality. At first, we analyze to which extent currently available open-source emulators support network configurations and how user-friendly they are. With these insights, we describe, how an ease-to-use emulator is implemented and may run as a Network Emulator as a Service (NEaaS). Therefore, virtualization plays a major role in order to deploy a NEaaS based on Kathará.

Dijkstra’s algorithm has been a popular solution for the shortest path problem, but repetitive use of it to find multiple paths is not scalable. The Multiple Disjoint Path Algorithm (MDPAlg), published in 2021, proposes the use of a single full graph to construct multiple disjoint paths. This paper proposes modifications to the algorithm to include a delay constraint, which is important in time-sensitive applications. Different delay constraint least-cost routing algorithms are compared in a comprehensive manner to evaluate the benefits of the adapted MDPAlg algorithm. Fault tolerance, and thereby reliability, is ensured by generating multiple link-disjoint paths from source to destination.

The aim is to predict the performance of a HIL test bench for open-loop re-injection in the context of scalability. HIL test benches are distributed computer systems including software, hardware, and networking devices. They are used to validate complex technical systems, but have not yet been system under study themselves. Our approach is to use measurements from the HIL system to create an empirical model for arrival and service curves. We predict the performance and design the previously unknown parameters of the HIL simulator with network calculus (NC), namely the buffer sizes and the minimum needed pre-buffer time for the playback buffer. We furthermore show, that it is possible to estimate the CPU load from arrival and service-curves based on the utilization theorem, and hence estimate the scalability of the HIL system in the context of the number of sensor streams.
