Dies ist der 20. Artikel unseres Blogfokus „Salafismus in Deutschland“. Bislang haben sich über 700 junge Menschen aus Deutschland den gewaltbereiten Salafisten des IS angeschlossen. Sie haben die Bundesrepublik verlassen und sind in den Jihad gezogen. Die mediale Diskussion beschränkt sich bei der Diskussion darüber, wie dies zu verhindern sei, zumeist auf sicherheitspolitische Maßnahmen. Das sind Maßnahmen, die auf Bundes- oder Länderebene durchgeführt werden. In der Prävention von Radikalisierung spielen allerdings die Kommunen eine entscheidende Rolle. Dieser Beitrag beleuchtet die Maßnahmen, die auf kommunaler Ebene getroffen werden (sollten) – von verschiedenen Präventionsangeboten bis hin zu Chancen kommunaler Vernetzung...
This paper documents the methodology underlying the construction of a global database of gross foreign asset and liability positions for 153 countries over the period 1970 to 2004 and illustrates some key data characteristics. The data cover both inflows and outflows of capital and thus allow for an assessment of the degree of international financial integration. In addition to net foreign asset stocks, we also provide details on the composition of the main asset and liability categories, namely the foreign direct investment, equity investment and debt components. Finally, we report on valuation changes as one of the main sources of discrepancy between transaction-based capital flow data and stock values of investment positions.

Zum Themenfeld "Diversität und Vielfalt" diskutierten im Rahmen des 8. Treffens des Nachwuchsnetzwerkes "Stadt, Raum, Architektur" Wissenschaftler_innen aus den Sozial-, Geistes- und Raumwissenschaften an den Instituten für Humangeographie, Kulturanthropologie und Europäische Ethnologie der Goethe-Universität Frankfurt am Main am 9. und 10. November 2012. Vor dem Hintergrund aktueller Debatten um die Konzeptualisierung von sowie den praktischen Umgang mit soziokultureller Vielfalt fand ein produktiver Austausch aus den Perspektiven der Stadtplanung, der Architekturwissenschaft sowie der sozial- und kulturwissenschaftlichen Stadt- und Raumforschung statt. Die Ergebnisse dieser interdisziplinären Auseinandersetzung hinsichtlich einer globalen Diskursverschiebung von "Multikulturalismus" zu "Diversität" und der Adaption entsprechender Strategien in Politik, Wirtschaft und Gesellschaft werden in diesem Tagungsbericht anhand theoretischer Ansätze zu "Super-Diversity", Kosmopolitismus und Transnationalismus diskutiert. Empirisch werden insbesondere Fragen zu Standortmarketing, Integrationspolitiken und der Verräumlichung von Diversität sowie konkreter Praktiken der Segregation, Marginalisierung und Aushandlung von Differenz aufgegriffen. Abschließend wird die Frage nach Konflikten und Potenzialen einer "neuen Diversität" aus stadtplanerischer, dekolonialer und poststrukturalistischer Perspektive diskutiert.
Der Diskurs über Integration und Integrationsmechanismen fand seinen Beginn in der Migrationsforschung, deren Anfänge bis in die erste Hälfte des 19. Jahrhunderts zurückreichen . Innerhalb dieses Feldes fanden immer wieder Wandlungen der Ausgestaltung des Begriffs der Integration statt, da die theoretischen Konzepte in unterschiedlichen gesellschaftlichen sowie historischen Kontexten entstanden sind bzw. entstehen. Heute existiert eine Vielzahl an theoretischen Perspektiven auf Integration, die eine hohe Heterogenität und auch Interdisziplinarität aufweisen. Generell zeigt sich somit, dass, wenn von Integration gesprochen wird, nicht wirklich klar ist, was unter dem Begriff zu verstehen ist. Die vorliegende Arbeit macht es sich somit zur Aufgabe, den Begriff der Integration und damit verbundene Zielvorstellungen aus Sicht der Akteurinnen und Akteure in Sportorganisationen zu beleuchten. Dafür wird eine Studie im Mixed-Methods-Design durchgeführt, die eine fragebogenbasierte Umfrage, explorative Interviews mit Vereinsvorständen und vertiefende Leitfadeninterviews mit Vereinsmitgliedern umfasst. Ein besonderer Fokus der Gruppenvergleiche liegt dabei auf Personen mit und ohne Migrationshintergrund, um die Perspektive von Personen mit Migrationshintergrund selbst in den Diskurs einbringen zu können. Da sich subjektive Sichtweisen auch aufgrund weiterer Faktoren unterscheiden können, werden außerdem Zusammenhänge zwischen sozialstrukturellen Merkmalen sowie Merkmalen der Vereine und subjektiven Sichtweisen auf Integration untersucht.
Die vorliegende Beispielerhebung erfasst und analysiert die Sprachbiographien von Freiburger Studierenden mit Migrationshintergrund. Sprachbiographien dienen der Darstellung eines Lebens bzw. einer Lebensspanne unter dem Gesichtspunkt der Sprachentwicklung mit dem Ziel der Rekonstruktion eines Gesamtbildes der sprachlichen Entwicklung einer Person in ihrem gesellschaftlichen Umfeld. Mithilfe der Sprachbiographien lassen sich Rückschlüsse auf die sprachliche und soziale Identität der Personen sowie auf den Zusammenhang zwischen der individuellen Sprachentwicklung und den für sie relevanten Lebensbedingungen ziehen. Besondere Bedeutung kommt hierbei der Rolle von (sprachlicher) Identität beim Integrationsprozess zu.
In April 2002 the European Central Bank (ECB) and the Center for Financial Studies (CFS) launched the ECB-CFS Research Network to promote research on “Capital Markets and Financial Integration in Europe”. The ECB-CFS research network aims at stimulating top-level and policy-relevant research, significantly contributing to the understanding of the current and future structure and integration of the financial system in Europe and its international linkages with the United States and Japan. This report summarises the work done under the network after two years. Over time the network formed a coherent and growing group of researchers interested in the integration of European financial markets, while using light organisational structures and budgets. The members of this evolving group met repeatedly at the events organised by the network to present the latest results of their research and to share views on policy options. In this sense, the “network of people” intended at the start was created. Overall, the network aroused great interest, as leading academic researchers, researchers from the main policy institutions and high-level policy makers participated actively in it by presenting research results, through speeches and in policy panels. It also stimulated a new research field on securities settlement systems, an area of high policy relevance and interest to the ECB that had not attracted much interest in the research community beforehand. Also, the network seems to have triggered several related outside initiatives by international institutions, such as the IMF or the OECD. During its first two years the network was organised around three workshops and a final symposium on 10-11 May 2004. To focus research resources and to ensure medium-term policy relevance, a limited number of areas have been given top priority: bank competition and the geographical scope of banking; international portfolio choices and asset market linkages between Europe, the United States and Japan; European bond markets; European securities settlement systems; and the emergence and evolution of new markets in Europe (in particular start-up financing markets). In order to stimulate further research focused on the priority fields of the network, the ECB Lamfalussy research fellowships were established. These fellowships sponsor projects proposed by young researchers, both a dvanced doctoral students and younger professors. Five Lamfalussy fellowships were granted in 2003 and five more in 2004. The first papers from this program have already been issued in the ECB working paper series or are forthcoming. One of them won the prize for the best paper written by a Ph.D. student at the 2004 European Finance Association Meetings in Maastricht. Results of the network in the five top priority areas can be summarised as follows: Bank competition and the geographical scope of banking. First, integration does not appear to be very advanced in many retail banking markets. Second, some of the inherent characteristics of traditional loan and deposit business constrain the cross-border expansion of commercial banking, even in a common currency area. Hence, the implementation of some policies to foster cross-border integration in retail banking may be ineffective. Third, theoretical research suggests that supervisory structures may not be neutral towards further European banking integration. Finally, a stronger role of area-wide competition policies could be beneficial for further banking integration. This would also stimulate economic growth, as more competition in the banking sector induces financially dependent firms to grow more. European bond markets. While the government bond market has integrated rapidly with the EMU convergence process, its full integration has not yet been achieved. The introduction of a common electronic trading platform reduced transaction costs substantially, but yield spreads of long-term sovereign bonds of the euro area are still heterogeneous. This is largely explained by different sensitivities to an international risk factor, whereas liquidity differentials only play a role in conjunction with this latter factor. Somewhat surprisingly in this context, the dynamically developing corporate bond market exhibits a relatively high level of integration. There is also increasing evidence that the introduction of the euro has contributed to a reduction in the cost of capital in the euro area, in particular through the reduction of corporate bond underwriting fees. As a result, firms may wish to increase bond financing relative to equity financing. The development of a larger corporate bond market is also important for monetary policy. For example, US evidence suggests that the rating of corporate bonds may contribute to the persistence of recessions, as rating agencies´ policies affect firms asymmetrically in their access to the bond market over the business cycle. US evidence also suggests that liquidity conditions in stock and bond markets tend to be positively correlated. European securities settlement systems. European securities settlement infrastructures are highly fragmented and further integration and/or consolidation would exploit economies of scale that could greatly benefit investors. It is not clear, however, whether direct public intervention in favour of consolidation would lead to the highest level of efficiency, for example because of the existence of strong vertical integration between trading and securities platforms (“silos”). In contrast, promoting open access to clearing and settlement systems could lead to consolidation and the highest level of efficiency. Finally, regarding concerns about unfair practices by Central Securities Depositories (CSDs) toward custodian banks, regulatory interventions favouring custodian banks should be discouraged, as long as CSDs are not allowed to price discriminate between custodian banks and investor banks. The emergence and evolution of new markets in Europe (in particular start-up financing markets). While fairly well integrated, “new markets” and start-up financing are less developed and integrated in Europe than in the United States. However, new markets and venture capitalists are the most important intermediaries for the financing of projects with high risk but with potentially very high return. The analysis carried out within the network reveals that European start-up financiers are mostly institutional investors, while US venture capitalists are mostly rich individuals. Also, new markets are essential for the development of start-up finance in Europe, as they provide an exit strategy for start-up financiers who can then sell new successful projects using initial public offerings. Finally, the legal framework affects the development of venture capital firms. For example, very strict personal bankruptcy laws constrain early stage entrepreneurs, reducing demand for venture capital finance. International portfolio choices and asset market linkages between Europe, the United States and Japan. At a global scale, asset market linkages have increased recently. For example, major economies such as the United States and the euro area have become more financially interdependent. This phenomenon can be observed in stock and bond markets as well as in money markets, where the main direction of spillovers has recently been from the US to the euro area. Country-specific shocks now play a smaller role in explaining stock return variations of firms whose sales are internationally diversified. Increases in firmby-firm market linkages are a global phenomenon, but they are stronger within the euro area than in the rest of the world. Various other phenomena also increase market linkages and therefore the likelihood that financial shocks spread across countries. One example is the use of global bonds. Finally, the nowadays more direct access of unsophisticated investors to financial markets may increase volatility. Other areas. Financial integration affects financial structures, but it does not need to lead to their convergence across countries. Financial structures matter for growth, as market-oriented financial systems benefit all sectors and firms, whereas bank-based systems primarily benefit younger firms that depend on external finance. Moreover, good corporate governance increases firms’ value. In particular, the dual board system, where the monitoring and advising roles of the board of directors are separated, is found to dominate the single board structure. Therefore, the further development of the European single market should strongly require good corporate governance. In general, well designed institutions foster entrepreneurial activity, partly by relaxing capital constraints. The results of the network clearly illustrated the substantial effects the introduction of the euro had on euro area financial markets. In addition to the effects on bond markets, stock markets and the cost of capital summarised above, research produced showed that the single currency had its strongest effects on money markets, whose unsecured segment is now completely integrated. Without any doubt the euro generally enhanced the liquidity and efficiency of euro area financial markets, and ongoing initiatives such as the European Union’s Financial Services Action Plan will help to continue this process. In sum, in the first two years the network has established itself as the hub for the research debate on European financial integration. Some of the best papers produced by the network, leading to the conclusions mentioned above, are currently being considered for publication in two special issues of academic journals. An issue of the Oxford Review of Economic Policy on “European financial integration” is published contemporaneously with this report, and an issue of the Review of Finance is planned for next year. The current policy context, the gradual progress of integration as well as the creation of other related non-ECB or non-CFS initiatives on financial integration suggest that this topic will remain high on the agendas of policy makers and academics for the years to come. Therefore, the ECB Executive Board and the CFS decided to continue the network, refocusing its priorities. Three priority areas have been added: 1) The relationship between financial integration and financial stability, 2) EU accession, financial development and financial integration, and 3) financial system modernisation and economic growth in Europe. These three areas have become particularly important at the current juncture, but have not received particularly strong attention in the first two years of the network. For example, the area of financial stability research was highlighted by the ECB research evaluators as an area deserving further development. Moreover, despite the results found in the first two years of the network, new developments remain to be further explored in the earlier priority areas. A three-year extension is envisaged, running from after the May 2004 symposium until 2007, with two events to be held per year. The threeyear period is long enough to consider the first effects of the Financial Services Action Plan. It also constitutes a realistic horizon for the ambitious agenda implied by the three new priorities. The generally light organisational structure and working of the network will not be changed. In addition, given the value of the Lamfalussy fellowship research program in inducing further research in the areas of the network, the program has also been extended for all the research topics in the area of the network.
Im Herbst 2007 entbrannte der Streit um den Bau einer Moschee im Frankfurter Stadtteil Hausen. In der vorliegenden Arbeit wird die Repräsentation dieses Streits als "Kulturkonflikt" oder als "Integrationsproblem" zum Anlass genommen, nach den diskursiven Grenzziehungen gegenüber MuslimInnen innerhalb der Auseinandersetzung zu fragen. Prozesse der Zuschreibung und Essentialisierung werden hinsichtlich der Konzeptualisierung von Ethnizität und kultureller Identität in den Blick genommen und in Zusammenhang mit rassismustheoretischen Ansätzen dargestellt. Die Beobachtungen am konkreten Fall des Frankurter Moscheebaustreits werden so eingeordnet in die aktuellen Debatten zum Islam und zu Islamophobie in Europa.
Regionale Kooperation und Integration im Sub-Sahara Afrika – Eine dritte Welle der Regionalisierung?
(2015)
Vor allem seit Mitte der 1990er Jahre ist regionale Kooperation und Integration im sub-saharischen Afrika zu einem Trendphänomen geworden, das immer mehr Politikfelder berührt. Mit der so genannten 2. Welle der Regionalisierung erhofften sich viele afrikanische Staaten nicht nur neue Lösungen für ihre zahlreichen (sicherheits-)politischen, ökonomischen und sozialen Probleme. Vielmehr können die Versuche zur vertieften dauerhaften Kooperation und Integration auf dem Kontinent auch als Antwort auf globale Entwicklungen, Interdependenzen und integrative Erfolgsgeschichten (z.B. EU, ASEAN) betrachtet werden. In die derzeit existierenden 19 Regionalorganisationen in Afrika (davon 14 größere und fünf kleinere), werden demnach sehr viele Hoffnungen und Erwartungen, nicht nur von Seiten der Regierungen, sondern neuerdings auch von Seiten externer und zivilgesellschaftlicher Kräfte gesteckt. Zunehmend sind in verschiedenen Organisationen wie der East African Community (EAC), der Economic Community of West African States (ECOWAS) oder der Southern African Development Community nicht mehr nur kooperative, sondern dezidiert integrative Formen der Zusammenarbeit feststellbar. Befindet sich das sub-saharische Afrika daher auf dem Weg zu einer neuen, einer dritten Welle der Regionalisierung?
Das Buch beschreibt die Nutzung türkischer populärer Musik und ihre Bedeutung für türkische Jugendliche in Deutschland. Es zeigt auf, dass die Nutzung türkischer Musik nicht die Ursache oder Folge einer Unfähigkeit oder eines Unwillens zur Integration ist, sondern vielmehr ein konstruktives Element innerhalb des individuellen Integrationsprozesses.
Objectives: The aim of the present study was to characterize the cellular reaction to a xenogeneic resorbable collagen membrane of porcine origin using a subcutaneous implantation model in Wistar rats over 30 days.
Materials and methods: Ex vivo, liquid platelet-rich fibrin (PRF), a leukocyte and platelet-rich cell suspension, was used to evaluate the blood cell membrane interaction. The material was implanted subcutaneously in rats. Sham-operated rats without biomaterial displayed physiological wound healing (control group). Histological, immunohistological, and histomorphometric analyses were focused on the inflammatory pattern, vascularization rate, and degradation pattern.
Results: The membrane induced a large number of mononuclear cells over the observation period, including lymphocytes, macrophages, and fibroblasts. After 15 days, multinucleated giant cells (MNGCs) were observed on the biomaterial surface. Their number increased significantly, and they proceeded to the center of the biomaterial on day 30. These cells highly expressed CD-68, calcitonin receptor, and MMP-9, but not TRAP or integrin-ß3. Thus, the membrane lost its integrity and underwent disintegration as a consequence of the induction of MNGCs. The significant increase in MNGC number correlated with a high rate of vascularization, which was significantly higher than the control group. Physiological wound healing in the control group did not induce any MNGCs at any time point. Ex vivo blood cells from liquid-PRF did not penetrate the membrane.
Conclusion: The present study suggests a potential role for MNGCs in biomaterial degradation and questions whether it is beneficial to accept them in clinically approved biomaterials or focus on biomaterials that induce only mononuclear cells. Thus, further studies are necessary to identify the function of biomaterial-induced MNGCs.
Clinical relevance: Understanding the cellular reaction to biomaterials is essential to assess their suitability for specific clinical indications and outline the potential benefit of specific group of biomaterials in the respective clinical indications.
