One key concern was that her decision would signal an open-door policy to aspiring migrants worldwide - thus further increasing migration to Germany and making the country permanently more attractive to irregular and humanitarian migrants. This 'pull-effect' hypothesis has been a mainstay of policy discussions ever since. With the continued global rise in forced displacement, not appearing welcoming to migrants has become a guiding principle for the asylum policy of many large receiving countries. In this article, we exploit the unique case study that Merkel's 2015 decision provides for answering the fundamental question of whether welcoming migration policies have sustained effects on migration towards destination countries. We analyze an extensive range of data on migration inflows, migration aspirations and online search interest between 2000 and 2020. The results reject the 'pull effect' hypothesis while reaffirming states' capacity to adapt to changing contexts and regulate migration.}, language = {en} } @article{KuhlmannFranzkePetersetal.2024, author = {Kuhlmann, Sabine and Franzke, Jochen and Peters, Niklas and Dumas, Beno{\^i}t Paul}, title = {Institutional designs and dynamics of crisis governance at the local level}, series = {Policy design and practice}, journal = {Policy design and practice}, publisher = {Taylor \& Francis}, address = {London}, issn = {2574-1292}, doi = {10.1080/25741292.2024.2344784}, pages = {1 -- 21}, year = {2024}, abstract = {This article analyses the institutional design variants of local crisis governance responses to the COVID-19 pandemic and their entanglement with other locally impactful crises from a cross-country comparative perspective (France, Germany, Poland, Sweden, and the UK/England). The pandemic offers an excellent empirical lens for scrutinizing the phenomenon of polycrises governance because it occurred while European countries were struggling with the impacts of several prior, ongoing, or newly arrived crises. Our major focus is on institutional design variants of crisis governance (dependent variable) and the influence of different administrative cultures on it (independent variable). Furthermore, we analyze the entanglement and interaction of institutional responses to other (previous or parallel) crises (polycrisis dynamics). Our findings reveal a huge variance of institutional designs, largely evoked by country-specific administrative cultures and profiles. The degree of de-/centralization and the intensity of coordination or decoupling across levels of government differs significantly by country. Simultaneously, all countries were affected by interrelated and entangled crises, resulting in various patterns of polycrisis dynamics. While policy failures and "fatal remedies" from previous crises have partially impaired the resilience and crisis preparedness of local governments, we have also found some learning effects from previous crises.}, language = {en} } @article{Kraft2023, author = {Kraft, Julia}, title = {Soziales Vertragsrecht}, series = {Impulse Spezial}, journal = {Impulse Spezial}, publisher = {Roman Herzog Institut e.V.}, address = {M{\"u}nchen}, pages = {4 -- 5}, year = {2023}, language = {de} } @article{GutzeitTiberius2023, author = {Gutzeit, Lilly Joan and Tiberius, Victor}, title = {Business and management research on the motion picture industry}, series = {Journalism and media}, volume = {4}, journal = {Journalism and media}, number = {4}, publisher = {MDPI}, address = {Basel}, issn = {2673-5172}, doi = {10.3390/journalmedia4040076}, pages = {1198 -- 1210}, year = {2023}, abstract = {The motion picture industry is subject to extensive business and management research conducted on a wide range of topics.

Contrastive corpus studies demonstrate that oral genres include longer average anaphoric distance than written genres, if the distance is measured in terms of clauses (Fox, 1987; Aktas \& Stede, 2020). We designed an experiment in order to examine the contrasts in oral and written mediums, using the same genre. We aim to gain more insight about the impact of the medium, in a situation where both mediums convey a similar level of spontaneity, informality and interactivity. We designed a story continuation study, where the participants are recruited via crowdsourcing. To our knowledge, this is the first study of its kind, where anaphoric distance is manipulated systematically in a language production experiment in order to examine medium distinctions. We observed that participants use more pronouns in oral medium than in written medium if the anaphoric distance is long. This result is in line with the implications of the earlier corpus-based research. In addition, our results indicate that anaphoric distance has a larger effect in referential choice for the written medium.}, language = {en} } @article{Scianna2022, author = {Scianna, Bastian Matteo}, title = {Directing the war from triumph to disaster}, series = {The Routledge History of the Second World War}, journal = {The Routledge History of the Second World War}, editor = {Bartrop, Paul R.}, publisher = {Routledge}, address = {Abingdon}, isbn = {9780429455353}, doi = {10.4324/9780429455353-16}, pages = {181 -- 194}, year = {2022}, abstract = {After the Second World War, Adolf Hitler and Benito Mussolini were singled out as evil geniuses who misled the masses and plunged them into an "unwanted war."

It was further asserted that Germany and Italy had not been able to secure a victory due to the dictators' meddling. Yet, as this chapter shows, there are important differences between the German and Italian cases. The chapter compares both the command structures in which the dictators operated as well as their grand strategies and how they cooperated during the war. Their personal relationship will be also analyzed, as it is impossible to look at the Axis without understanding the complex personal relationship at the very top. The strategies of both Hitler and Mussolini will be looked at and how each leader behaved in terms of working with their closest ally, together with some examples of cooperation on the lower military rungs.}, language = {en} } @article{Zass2021, author = {Zass, Alexander}, title = {Gibbs point processes on path space}, series = {Markov processes and related fields}, volume = {28}, journal = {Markov processes and related fields}, number = {3}, publisher = {Polymat}, address = {Moscow}, issn = {1024-2953}, doi = {10.20347/WIAS.PREPRINT.2859}, pages = {329 -- 364}, year = {2021}, abstract = {We present general existence and uniqueness results for marked models with pair interactions, exemplified through Gibbs point processes on path space.

This article argues that the origins and political histories that the concepts of demos and democracy stand on provide a firm ground to resist the attempts at their current nativist/nationalist closure.

The acquisition of increasingly precise mental number line representations is assumed to support arithmetic learning in children. It is further suggested that sensorimotor experiences shape the development of number concepts and arithmetic learning, and that mental arithmetic can be characterized as "motion along a path" and might constitute shifts in attention along the mental number line. The present study investigated whether movements in physical space influence mental arithmetic in primary school children, and whether the expected effect depends on concurrency of body movements and mental arithmetic. After turning their body towards the left or right, 48 children aged 8 to 10 years solved simple subtraction and addition problems. Meanwhile, they either walked or stood still and looked towards the respective direction. We report a congruency effect between body orientation and operation type, i.e., higher performance for the combinations leftward orientation and subtraction and rightward orientation and addition. We found no significant difference between walking and looking conditions. The present results suggest that mental arithmetic in children is influenced by preceding sensorimotor cues and not necessarily by concurrent body movements.}, language = {en} } @article{KonakvandeWaterDoeringetal.2023, author = {Konak, Orhan and van de Water, Robin and D{\"o}ring, Valentin and Fiedler, Tobias and Liebe, Lucas and Masopust, Leander and Postnov, Kirill and Sauerwald, Franz and Treykorn, Felix and Wischmann, Alexander and Gjoreski, Hristijan and Luštrek, Mitja and Arnrich, Bert}, title = {HARE}, series = {Sensors}, volume = {23}, journal = {Sensors}, number = {23}, publisher = {MDPI}, address = {Basel}, issn = {1424-8220}, doi = {10.3390/s23239571}, pages = {23}, year = {2023}, abstract = {Sensor-based human activity recognition is becoming ever more prevalent. The increasing importance of distinguishing human movements, particularly in healthcare, coincides with the advent of increasingly compact sensors. A complex sequence of individual steps currently characterizes the activity recognition pipeline. It involves separate data collection, preparation, and processing steps, resulting in a heterogeneous and fragmented process. To address these challenges, we present a comprehensive framework, HARE, which seamlessly integrates all necessary steps. HARE offers synchronized data collection and labeling, integrated pose estimation for data anonymization, a multimodal classification approach, and a novel method for determining optimal sensor placement to enhance classification results. Additionally, our framework incorporates real-time activity recognition with on-device model adaptation capabilities. To validate the effectiveness of our framework, we conducted extensive evaluations using diverse datasets, including our own collected dataset focusing on nursing activities. Our results show that HARE's multimodal and on-device trained model outperforms conventional single-modal and offline variants. Furthermore, our vision-based approach for optimal sensor placement yields comparable results to the trained model. Our work advances the field of sensor-based human activity recognition by introducing a comprehensive framework that streamlines data collection and classification while offering a novel method for determining optimal sensor placement.}, language = {en} }
