The real-time recognition and precise correction of baseline shifts in strong-motion records is a critical issue for GPS and accelerometer combined processing. This paper proposes a method to adaptively recognize and correct baseline shifts in strong-motion records by utilizing GPS measurements using two phases Kalman filter. By defining four kinds of learning statistics and criteria, the time series of estimated baseline shifts can be divided into four time intervals: initialization, static, transient and permanent. During the time interval in which the transient baseline shift is recognized, the dynamic noise of the Kalman filter system and the length of the baseline shifts estimation window are adaptively adjusted to yield a robust integration solution. The validations from an experimental and real datasets show that acceleration baseline shifts can be precisely recognized and corrected, thus, the combined system adaptively adjusted the estimation strategy to get a more robust solution.

Despite scarce empirical evidence, introducing new vocabulary in semantic categories has long been standard in second language teaching. We examined the effect of learning context on encoding, immediate recall and integration of new vocabulary into semantic memory by contrasting categorically related (novel names for familiar concepts blocked by semantic category) and unrelated (mixed semantic categories) learning contexts. Two learning sessions were conducted 24 hours apart, with each participant exposed to both contexts. Subsequently, a test phase examined picture naming, translation and picture-word interference tasks. Compared to the unrelated context, the categorically related context resulted in poorer naming accuracy in the learning phase, slower response latencies at the immediate recall tasks and greater semantic interference in the picture-word interference task (picture naming in L1 with semantically related novel word distractors). We develop a theoretical account of word learning that attributes observed differences to episodic rather than semantic memory.
Background: The development of bioinformatics databases, algorithms, and tools throughout the last years has lead to a highly distributedworld of bioinformatics services. Without adequatemanagement and development support, in silico researchers are hardly able to exploit the potential of building complex, specialized analysis processes from these services. The Semantic Web aims at thoroughly equipping individual data and services with machine-processable meta-information, while workflow systems support the construction of service compositions. However, even in this combination, in silico researchers currently would have to deal manually with the service interfaces, the adequacy of the semantic annotations, type incompatibilities, and the consistency of service compositions. Results: In this paper, we demonstrate by means of two examples how Semantic Web technology together with an adequate domain modelling frees in silico researchers from dealing with interfaces, types, and inconsistencies. In Bio-jETI, bioinformatics services can be graphically combined to complex services without worrying about details of their interfaces or about type mismatches of the composition. These issues are taken care of at the semantic level by Bio-jETI’s model checking and synthesis features. Whenever possible, they automatically resolve type mismatches in the considered service setting. Otherwise, they graphically indicate impossible/incorrect service combinations. In the latter case, the workflow developermay either modify his service composition using semantically similar services, or ask for help in developing the missing mediator that correctly bridges the detected type gap. Newly developed mediators should then be adequately annotated semantically, and added to the service library for later reuse in similar situations. Conclusion: We show the power of semantic annotations in an adequately modelled and semantically enabled domain setting. Using model checking and synthesis methods, users may orchestrate complex processes from a wealth of heterogeneous services without worrying about interfaces and (type) consistency. The success of this method strongly depends on a careful semantic annotation of the provided services and on its consequent exploitation for analysis, validation, and synthesis. We are convinced that these annotations will become standard, as they will become preconditions for the success and widespread use of (preferred) services in the Semantic Web
As expected, the traditions of national-state migration policies continue to play a very important role, path-dependence in this policy field remains high. The distribution of competences in migration policy and the integration of migrants in the nation states continues to be very different. When implementing integration strategies at grassroots level, the respective policies should be tailored to the profile of both the local migrant community and the native population. Besides better migration management in local administration and the interaction of top-down and bottom-up efforts to integrate migrants is of importance.
Deutschland
(2023)
Das Kapitel beginnt mit einem kurzen historischen Überblick über den Übergang Deutschlands im 20. und 21. Jahrhundert von einem Transit- und Auswanderungsland zu einem Einwanderungsland. Der nächste Teil des Kapitels befasst sich mit den Herausforderungen und Problemen der deutschen Einwanderungspolitik in einem föderalen Mehrebenensystem. Abschließend analysiert das Kapitel einige Trends in der deutschen Migrationspolitik seit der Flüchtlingskrise 2015, wie etwa Veränderungen im Parteiensystem und in den Konzepten, die der Migrationspolitik zugrunde liegen, um die Zuwanderung nach Deutschland besser zu steuern, zu kontrollieren und zu begrenzen.
Viele der mittelost- und südosteuropäischen Länder haben mit der Migration ihrer Staatsbürger nach Westeuropa zu kämpfen und beklagen den brain drain ihrer jungen und gut ausgebildeten Generation. Dieses Buch widmet sich der Migration bulgarischer Staatsbürger nach Deutschland und analysiert die positiven sowie negativen Auswirkungen der Migration auf Bulgarien als Herkunftsland selbst. Es werden die Daten, Personengruppen und Ursachen der Migration unter Berücksichtigung der Push- und Pull-Faktoren beider Länder seit dem EU-Beitritt 2007, insbesondere seit der EU-Arbeitnehmerfreizügigkeit 2014, analysiert. Ferner steht die Frage im Vordergrund, wie der bulgarische Staat und die Zivilgesellschaft mit dem Phänomen der Massenmigration umgehen und was zusätzlich getan werden könnte, um die Migration gezielter zu steuern und so mehr Bulgaren für eine Zukunft in der Heimat zu begeistern.
Die Integration Europas bleibt für die Sozialwissenschaften eine Quelle der Inspiration und Herausforderung. Auch 53 Jahre nach Unterzeichnung der Römischen Verträge ist der Kontinent weiter in Bewegung, geht es um die Vision seiner zukünftigen Gestalt ebenso wie um die Regelung vielfältigster Tagesprobleme. Um zu dieser Debatte einen spezifischen Beitrag zu leisten, fand im Juni 2010 an der Universität Potsdam eine deutsch-polnische Konferenz zum Thema „Europa als Inspiration und Herausforderung aus sozialwissenschaftlicher Sicht“ statt. Dabei wurden unterschiedliche Ansätze der europawissenschaftlichen Forschungen in den beteiligten Einrichtungen (z. B. aus der Sicht von Politologen, Soziologen, Historikern oder Kulturwissenschaftlern) präsentiert. Zugleich diente die Konferenz dazu, das wissenschaftliche Forschungsinteresse am „nahen Osten“ wieder zu stärken.
The chapter begins with a brief historical overview of Germany’s transition in the twentieth and twenty-first century from a transit and emigration country to one of immigration. The next part of this chapter looks at the challenges and problems facing German immigration policy within a multi-level federal system. Finally, the chapter gives an analysis of some of the trends in German migration policy since the refugee crisis in 2015, such as changes in the party system and in the concepts underlying migration policies to better manage, control and limit immigration to Germany.
Moroccans are the largest group of immigrants in Spain. Once they arrive at the new place, one of their first necessities is to access shelter. Focusing on the south-eastern region of Murcia in Spain and combining quantitative and qualitative data, I explore the process of housing market integration of Moroccan migrants. Special attention is paid to the dynamics of this process and the role that the interaction between the supply side and the foreign demand of accommodation plays. Thereby, I will emphasise how an unfavourable structure of the housing market, along with behaviour of local private landlords on the supply side leads to considerable problems concerning the housing market integration of migrants in Spain. Thus, this paper aims to give a more accurate interpretation of the dynamics influencing the housing outcomes of migrants in the studied area.
Russian Jews who left the Former Soviet Union (FSU) and its Successor States after 1989 are considered as one of the best qualified migrants group worldwide. In the preferred countries of destination (Israel, the United States and Germany) they are well-known for cultural self-assertion, strong social upward mobility and manifold forms of self organisation and empowerment. Using Suzanne Kellers sociological model of “Strategic Elites”, it easily becomes clear that a huge share of the Russian Jewish Immigrants in Germany and Israel are part of various elites due to their qualification and high positions in the FSU – first of all professional, cultural and intellectual elites (“Intelligentsija”). The study aimed to find out to what extent developments of cultural self-assertion, of local and transnational networking and of ethno-cultural empowerment are supported or even initiated by the immigrated (Russian Jewish) Elites. The empirical basis for this study have been 35 half-structured expert interviews with Russian Jews in both countries (Israel, Germany) – most of them scholars, artists, writers, journalists/publicists, teachers, engineers, social workers, students and politicians. The qualitative analysis of the interview material in Israel and Germany revealed that there are a lot of commonalities but also significant differences. It was obvious that almost all of the interview partners remained to be linked with Russian speaking networks and communities, irrespective of their success (or failure) in integration into the host societies. Many of them showed self-confidence with regard to the groups’ amazing professional resources (70% of the adults with academic degree), and the cultural, professional and political potential of the FSU immigrants was usually considered as equal to those of the host population(s). Thus, the immigrants’ interest in direct societal participation and social acceptance was accordingly high. Assimilation was no option. For the Russian Jewish “sense of community” in Israel and Germany, Russian Language, Arts and general Russian culture have remained of key importance. The Immigrants do not feel an insuperable contradiction when feeling “Russian” in cultural terms, “Jewish” in ethnical terms and “Israeli” / “German” in national terms – in that a typical case of additive identity shaping what is also significant for the Elites of these Immigrants. Tendencies of ethno-cultural self organisation – which do not necessarily hinder impressing individual careers in the new surroundings – are more noticeable in Israel. Thus, a part of the Russian Jewish Elites has responded to social exclusion, discrimination or blocking by local population (and by local elites) with intense efforts to build (Russian Jewish) Associations, Media, Educational Institutions and even Political Parties. All in all, the results of this study do very much contradict popular stereotypes of the Russian Jewish Immigrant as a pragmatic, passive “Homo Sovieticus”. Among the Interview Partners in this study, civil-societal commitment was not the exception but rather the rule. Traditional activities of the early, legendary Russian „Intelligentsija“ were marked by smooth transitions from arts, education and societal/political commitment. There seem to be certain continuities of this self-demand in some of the Russian Jewish groups in Israel. Though, nothing comparable could be drawn from the Interviews with the Immigrants in Germany. Thus, the myth and self-demand of Russian “Intelligentsija” is irrelevant for collective discourses among Russian Jews in Germany.
