Internal Migration. Challenges and Perspectives for the Research Infrastructure

Research on internal migration covers a wide range of issues with regard to the reasons, distance and direction of moves as well as the process of decision-making.

Several prospective longitudinal survey data do not represent essential aspects of internal migration.

Neighbourhood-based social integration. The importance of the local context for different forms of resource transfer

Due to their lack of financial resources, poor residents of deprived neighbourhoods are very much reliant on support and assistance from their personal networks. Studies refer to the key importance of neighbourhood contacts transcending social boundaries to promote upward social mobility. Based on a mix of quantitative and qualitative findings, this paper looks at the importance of social mix within a person’s neighbourhood and immediate surroundings for transferring different kinds of resources. The results show that even residents of deprived neighbourhoods can call on a well-developed support network to deal with everyday problems. The contribution also shows that network contacts to people endowed with more resources are no guarantee for the upward social mobility of the less well endowed. Indeed, it would seem that ‘getting-ahead’ resources are also accessible via their homogeneous networks. Much more to the point, the immediate surroundings turn out to be an important spatial context for contacts and resource transfers, especially for families with children.Peer reviewe

Marginale Gruppen auf dem Wohnungsmarkt: das Beispiel Bremen

"In diesem Arbeitspapier geht es um die räumliche Verteilung sozial benachteiligter Gruppen. Dabei werden unter anderem Wechselwirkungen zwischen Sozial- und Wohnungspolitik aufgezeigt und sowohl Quer- wie Längsschnittanalysen angewendet. Die Frage nach dem Ausmaß räumlicher Segregation in Bremen wird in zwei Schritten bearbeitet: Zunächst wird die Lage benachteiligter Gruppen auf dem Wohnungsmarkt in Bremen - etwa Anteil an den Sozialwohnungen, verfügbare Wohnfläche, räumliche Verteilung im Stadtgebiet - auf der Grundlage aggregierter Querschnittsdaten untersucht. Dann wird die Verdrängungsthese anhand individueller Längsschnittdaten überprüft.

Soziale Integration im Quartier: Förderung von Netzwerken und Begegnungen in zwei benachteiligten Sozialräumen Dortmunds

Angesichts der zunehmenden sozialräumlichen Polarisierung in vielen Städten stellt sich die Frage, inwieweit von Armut geprägte Gebiete eine zusätzlich benachteiligende Wirkung auf die soziale Lage ihrer Bewohner_innen haben. Basierend auf einem Zusammenspiel quantitativer und qualitativer Methoden wird im Rahmen des vorliegenden Forschungsvorhabens in zwei unterschiedlichen Quartieren in der Stadt Dortmund analysiert, inwieweit Haushalte in sozial benachteiligten Quartieren Zugang zu Unterstützungsleistungen durch soziale Kontakte erhalten und welchen Einfluss die soziale Zusammensetzung der unmittelbaren Wohnumgebung auf den Zugang zu Ressourcen hat. Die Ergebnisse zeigen, dass auch einkommensarme Bewohner_innen benachteiligter Quartiere auf ein recht gut ausgeprägtes Unterstützungsnetzwerk für die Alltagsorganisation zurückgreifen können. Es wird jedoch deutlich, dass Netzwerkkontakte zu ressourcenstärkeren Haushalten nicht automatisch die soziale Aufwärtsmobilität ressourcenschwacher Bewohner_innen befördern. Das Quartier bzw. die unmittelbare Wohnumgebung stellt sich als wichtiger räumlicher Kontext für Kontakte und Ressourcentransfer heraus. Hier werden durch lose Kontakte auch über alltagspraktische Unterstützungen hinaus wichtige Ressourcen vermittelt.In light of the increasing socio-spatial polarisation in many cities the question arises to what extent living in disadvantaged urban neighbourhoods has an additional negative effect on the residents‘ social status. Based on mixed methods approach, the research project seeks to analyse to what extent poor households in socially disadvantaged neighbourhoods have access to support networks. The project looks at the importance of social mix within a person's neighbourhood and his/her immediate surroundings for transferring different kinds of resources. The results show that even poor residents of deprived neighbourhoods can call on a welldeveloped support network for dealing with everyday problems. However, the analysis also illustrates that network contacts to people endowed with more resources are no guaranteed way of promoting the upward social mobility of those less well endowed. Much more to the point, their immediate surroundings turn out to be an important spatial context for contacts and resource transfers, in which also loose contacts can provide resources going beyond just 'getting-by’ resources

Migrantenquartiere - Ressource oder Benachteiligung?

"Seit mehreren Jahrzehnten ist ein hohes Maß an Zuwanderung nach Deutschland zu verzeichnen. Die größten in Deutschland lebenden Migrantengruppen bilden die seit längerem ansässigen Arbeitsmigrant(inn)en aus Südeuropa und der Türkei sowie die deutschstämmigen (Spät)Aussiedler(innen) aus den ehemaligen Ostblock-Staaten, die vor allem in den 1990er Jahren nach dem Zusammenbruch der kommunistischen Regierungen zugewandert sind. Räumlich konzentrieren sich die Migrant(inn)en und ihre Nachkommen vorwiegend in den größeren Städten und hier - aufgrund ihres vergleichsweise geringen Einkommens - in den weniger attraktiven Arbeiterquartieren und den Siedlungen des sozialen Wohnungsbaus. Der Beitrag fragt nach den Ursachen und sozialen Folgen der räumlichen Konzentration der Zuwanderinnen und Zuwanderer in den Migrantenquartieren der Städte. Deutlich wird, dass diese Quartiere - über die positiven Effekte der sozialen und psychischen Stabilisierung in der Anfangsphase der Eingliederung im Aufnahmeland hinaus - insbesondere aufgrund der mit der räumlichen Konzentration von Migrant(inn)en einhergehenden sozioökonomischen Segregation einkommensarmer Bevölkerungsgruppen deutlich negative Effekte auf den Eingliederungsprozess von Migrant(inn)en haben." (Autorenreferat)"For several decades Germany has registered high rates of immigration. Migrant labourers from Turkey and Southern Europe and their descendants who have long been residents in Germany form the largest group of persons with a migration history. The second largest group consists of ethnic Germans who mainly immigrated into Germany from the successor states of the former Soviet Union and from other East European states in the 1990s after the breakdown of communist regimes. The majority of those with migration backgrounds live in large cities and – because of their relatively low incomes - are concentrated particularly in less attractive working class neighbourhoods or in residential areas with a high percentage of social housing. The paper examines the reasons for and social consequences of the spatial concentration of migrant population in the urban migrant quarters. These quarters facilitate newly arrived migrants in adapting to the new environment by providing social networks. Migrants gain social and mental stability. But increasing length of the stay in these quarters has a distinctly negative effect on the migrants' integration process especially as a consequence of their spatial concentration in residential areas characterised by low income groups."

Application of Iridium Catalized Allylic Substitution Reactions in the Synthesis of Branched Triptamines and Homologues via Tandem Hydroformylation/Fischer Indole Synthesis

Combination of enantioselective allylation reactions with a tandem hydroformylation–Fischer indole synthesis sequence as a highly diversity-oriented strategy for the synthesis of tryptamines and homologues was explored. This modular approach allows the substituents at C3 of the indole core, the type of the amine moiety, and the distance of the amine moiety to the indole core in the final synthetic step to be defined. The starting materials required for the hydroformylation step were synthesized viairidium catalyzed enantioselective allylic substitution reactions in high yields and excellent enantioselectivities. The Rh catalyzed hydroformylation step in the presence of phenyl hydrazine, allows the in situ formed aldehyde to be trapped as the hydrazone. Subsequent acid catalyzed indolization furnishes the desired indole structures in moderate to good yields
