  abstract  = {Es gibt in Berlin eine einzigartige Vereinslandschaft im Amateur - und semiprofessionellen Fußballsport, in der einst von t{\"u}rkischen Migranten gegr{\"u}ndete Vereine einen festen Platz einnehmen. Fußballsport bietet einen sozialen Raum f{\"u}r Jugendliche verschiedener kultureller, ethnischer und religi{\"o}ser Herkunft, in dem Gruppen gebildet werden, um gegen einander zu konkurrieren. Ebenso er{\"o}ffnet Fußball dem Einzelnen die M{\"o}glichkeit, die G{\"u}ltigkeit und Relevanz von Vorurteilen und von g{\"a}ngigen Stereotypisierungen anderer Gruppen im Spielalltag einer st{\"a}ndigen Pr{\"u}fung zu unterziehen. Fußballspieler k{\"o}nnen sich sowohl zwischen multi-kulturellen als auch mono-ethnischen Gruppenkonstellationen, in einigen F{\"a}llen auch in transnationalen Konstellationen bewegen, womit sie dabei wesentlich an der Sinngebung ihrer eigenen sozialen Zugeh{\"o}rigkeit mitwirken, die sich aus dem Spannungsfeld von Selbst- und Fremdwahrnehmungsmustern ergibt. In Folge dessen werden in diesem Raum Anerkennungsmechanismen konstituiert. Die vorliegende Dissertation befasst sich mit dem allt{\"a}glichen Leben von t{\"u}rkisch-st{\"a}mmigen, jugendlichen Amateur- und semiprofessionellen Fußballspielern (delikanli), sowie von anderen sozialen Akteuren der t{\"u}rkischen Fußballwelt, wie zum Beispiel „{\"a}ltere" Fußballspieler (agbi) und Fußballtrainer (hoca). Hauptanliegen der Arbeit war die Rekonstruktion kollektiver Wahrnehmungs-, Deutungs - und Handlungsmuster von Mitgliedern t{\"u}rkischer Fußballvereine im allgemeinen und ihrer Selbstdarstellung aber auch ihrer Wahrnehmung der „Anderen" im besonderen. Mittels dieser Studie sollte nachvollzogen werden, ob und inwiefern sich traditionelle soziale Verhaltensmuster der gew{\"a}hlten Gruppe im technisch regulierten und stark Konkurrenz-orientierten Handlungsraum widerspiegeln und die reziproken Beziehungen zwischen dem „Selbst" und den „Anderen" regulieren. Dabei wurde die Relevanz von herkunftsbezogenen Stereotypisierungen und Vorurteilen in der kollektiven Konstitution von Selbstwahrnehmungen und Fremdverstehen im partikularen sozialen Feld (Bourdieu, 2001) des Fußballs rekonstruiert. In dieser Arbeit wurde dar{\"u}ber hinaus beleuchtet, welche Rolle t{\"u}rkische Fußballvereine auf der einen Seite bei der Entstehung sozialer Raumzugeh{\"o}rigkeit zu den Stadtquartieren in Berlin einnehmen und welche Art von Mechanismen der sozialen Integration sie in diesen Vereinen herstellen. Auf der anderen Seite wurde hinterfragt, inwiefern sie zur sozialen Koh{\"a}sion zwischen diversen Kulturen beitragen. Daher wurde gepr{\"u}ft, ob und inwiefern die negativ konnotierte ethnozentrische Wahrnehmung von „Differenz" (Bielefeld, 1998), die als soziales Konstrukt zwischen autochthonen und allochthonen Gruppen hergestellt wird, durch das Engagement der Vereinsakteure einen konstruktiven Wandel erf{\"a}hrt. {\"U}bergeordnetes Ziel all dieser Forschungsfragen war es, ein fundiertes Verst{\"a}ndnis {\"u}ber die Rolle von t{\"u}rkischen Fußballvereinen als soziale Mechanismen zu erlangen und deren Funktionsweise bei der Konstitution von Anpassungsstrategien in diesem sozialen Feld untersuchen. Detailliert wurde diese Rolle unter der Konzeptualisierung von sozialen Positionierungsmuster betrachtet, die als Gef{\"u}ge von Deutungen des Allt{\"a}glichen verstanden werden, das individuelle und kollektive Handlungsmuster und implizit Muster des Fremdverstehens sowie des othering im Migrationskontext reguliert. Eine Rekonstruktion der sozialen Positionierungsmuster bietet eine eingehende soziologische Untersuchung dieser Teilnehmergruppe, die zudem Aufschluss {\"u}ber die Bedeutung und das Verst{\"a}ndnis von ethnischer Zugeh{\"o}rigkeit f{\"u}r letztere gibt. Neben umfangreicher Feldbeobachtung wurden in dieser qualitativen Studie mit Spielern verschiedener Vereine insgesamt zehn Gruppendiskussionen (Bohnsack, 2004) innerhalb ihrer Mannschaften zu gemeinsamen allt{\"a}glichen Erlebnissen und Erfahrungen durchgef{\"u}hrt, aufgezeichnet und mittels sozialwissenschaftlichem hermeneutischem Verfahren (Soeffner, 2004) interpretiert. Auch mit anderen Vereinsmitgliedern, d. h. mit Trainern bzw. hoca, Vorsitzenden, Managern und Sponsoren wurden jeweils zehn narrative und sieben biographische Einzelinterviews sowie sieben Experteninterviews durchgef{\"u}hrt. Deren Analyse erlaubt es, die Rolle dieser Mitglieder sowie wirkende Autorit{\"a}tsmechanismen und kollektiv konstituierte Verhaltensmuster innerhalb der gesamten Vereinsgruppe zu rekonstruieren. Dabei wurde bezweckt, die Gesamtheit des sozialen Netzwerkes bzw. die Beziehungsschemata innerhalb der t{\"u}rkischen Fußballvereine Berlins zu verdeutlichen. In der Arbeit werden zwei Standpunkte der theoretischen Auseinandersetzung verwendet. Auf der einen Seite wird die Lebensweltanalyse (Sch{\"u}tz und Luckmann, 1979, 1990) angewendet, um das soziale Erbe der in der Vergangenheit gesellschaftlich konstituierten Titulierung „Menschen mit Migrationshintergrund" zu rekonstruieren, bzw. den Einfluss dieser sozialen Reproduktion auf die Wahrnehmungs-, Deutungs- und Handlungsmuster der Akteure zu untersuchen. Auf der anderen Seite wird die soziale Wirkung der tats{\"a}chlichen, allt{\"a}glichen Erfahrungsschemata im sozialen Feld des Fußballs auf die Selbstpositionierungen der Akteure mittels Goffmanscher Rahmenanalyse (Goffman, 1980) herausgearbeitet.},

  abstract  = {The globally distributed sperm whale (Physeter macrocephalus) has a partly matrilineal social structure with predominant male dispersal. At the beginning of 2016, a total of 30 male sperm whales stranded in five different countries bordering the southern North Sea. It has been postulated that these individuals were on a migration route from the north to warmer temperate and tropical waters where females live in social groups. By including samples from four countries (n = 27), this event provided a unique chance to genetically investigate the maternal relatedness and the putative origin of these temporally and spatially co-occuring male sperm whales. To utilize existing genetic resources, we sequenced 422 bp of the mitochondrial control region, a molecular marker for which sperm whale data are readily available from the entire distribution range. Based on four single nucleotide polymorphisms (SNPs) within the mitochondrial control region, five matrilines could be distinguished within the stranded specimens, four of which matched published haplotypes previously described in the Atlantic. Among these male sperm whales, multiple matrilineal lineages co-occur. We analyzed the population differentiation and could show that the genetic diversity of these male sperm whales is comparable to the genetic diversity in sperm whales from the entire Atlantic Ocean. We confirm that within this stranding event, males do not comprise maternally related individuals and apparently include assemblages of individuals from different geographic regions.

Die j{\"u}ngeren Interviewten gehen wiederum sehr unterschiedlich mit dem Verlust der Heimat und dem Bruch ihrer Erwerbsbiographie im Zuge der Antizionistischen Kampagne um. Die im Film vorgestellten Pers{\"o}nlichkeiten reichen vom erfolgreichen Musiker, {\"u}ber eine ehemalige Mitarbeiterin des israelischen Fernsehens bis hin zu einfachen Facharbeitern.

  abstract  = {The field of American Jewish studies has recently trained its focus on the transnational dimensions of its subject, reflecting in more sustained ways than before about the theories and methods of this approach. Yet, much of the insight to be gained from seeing American Jewry as constitutively entangled in many ways with other Jewries has not yet been realized. Transnational American Jewish studies are still in their infancy. This issue of PaRDeS presents current research on the multiple entanglements of American with Central European, especially German-speaking Jewries in the 19th and 20th centuries. The articles reflect the wide range of topics that can benefit from a transnational understanding of the American Jewish experience as shaped by its foreign entanglements.},

  abstract  = {Our understanding of the impact of climate-driven environmental change on prehistoric human populations is hampered by the scarcity of continuous paleoenvironmental records in the vicinity of archaeological sites. Here we compare a continuous paleoclimatic record of the last 20 ka before present from the Chew Bahir basin, southwest Ethiopia, with the available archaeological record of human presence in the region. The correlation of this record with orbitally-driven insolation variations suggests a complex nonlinear response of the environment to climate forcing, reflected in several long-term and short-term transitions between wet and dry conditions, resulting in abrupt changes between favorable and unfavorable living conditions for humans. Correlating the archaeological record in the surrounding region of the Chew Bahir basin, presumably including montane and lake-marginal refugia for human populations, with our climate record suggests a complex interplay between humans and their environment during the last 20 ka. The result may contribute to our understanding of how a dynamic environment may have impacted the adaptation and dispersal of early humans in eastern Africa. (C) 2015 Elsevier Ltd.

  abstract  = {Bats are top insect predators on farmland, yet they suffer from intensive farmland management. Here, we evaluated the seasonal activity patterns of European bats above large, arable fields and compared these patterns between ecologically distinct bat species. Using repeated passive acoustic monitoring on a total of 93 arable fields in 2 years in Brandenburg, Germany, we surveyed the activity of different bat species between early spring and autumn. We then used generalized additive mixed models to describe and compare the seasonal bat activity patterns between bat categories, which were build based on the affiliation to a functional group and migratory class, while controlling for local weather conditions. In general, the affiliation to a bat category in interaction with the season in addition to cloud cover and ambient air temperature explained a major part of bat activity. The season was also an important factor for the foraging activity of open-space specialists such as Nyctalus noctula but showed only a weak effect on species such as Pipistreilus nathusii which are adapted to edge-space habitats. Across the seasons, habitat use intensity was high during the period of swarming and migration and low during the energy demanding period of lactation. Seasonal patterns in foraging activity showed that open-space specialists foraged more intensively above agricultural fields during the migration period, while edge-space specialists foraged also during the energy demanding period of lactation. We conclude that the significant seasonal fluctuations in bat activity and significant differences between bat categories in open agricultural landscapes should be taken into consideration when designing monitoring schemes and management plans for bat species in regions dominated by agriculture. Also, management plans should be directed to improve the conditions on arable land especially for bat species which would be classified as narrow-space foragers such as Myotis species.

In the collection of papers, these promotive and protective factors range from peers and families, to teachers, to organisational context and climate. With continued disruptions in children's lives due to a pandemic, climate change, war, conflict and poverty, migration will remain a pressing concern and will continue to transform the student populations in our classrooms and schools for the foreseeable future.

  abstract  = {Being perceived as a foreigner regardless of one's generational status, citizenship, or self-identification is called foreigner objectification. This is a form of identity denial and is linked to psychological distress. To test how foreigner objectification could be measured in Europe, we assessed whether the Foreigner Objectification Scale demonstrated reliability and validity with German adolescents. The sample included 806 9th graders from 17 high schools. The results showed that the scale demonstrates good reliability, scalar measurement invariance across gender and citizenship status, and partial scalar measurement invariance across family heritage, generational status, and cultural self-identification. Adolescents who scored higher on the scale also reported greater school behavioral disengagement, lower life satisfaction, and stronger ethnic identity. Our findings suggest that the scale is psychometrically sound and is linked in theoretically consistent ways to adjustment and ethnic identity. We conclude that this scale offers another way to capture subtle discrimination experiences that add to a more comprehensive understanding of discrimination and the related implications in Europe.},

We follow here an approach of Walker et al. to backtrack and stack broadband waveforms from global network stations using traveltimes for a global Earth model to obtain the overall spatio-temporal development of the energy radiation of large earthquakes in a quick and robust way. We present results for selected events with well studied source processes (Kokoxili 14.11.2001, Tokachi-Oki 25.09.2003, Nias 28.03.2005). Further, we apply the technique in a semi-real time fashion to broadband data of earthquakes with a broadband magnitude >= 7 (roughly corresponding to Mw 6.5).

  abstract  = {Armed conflicts trigger region-specific mechanisms that affect land use change. Deforestation is presented as one of the most common negative environmental impacts resulting from armed conflicts, with relevant consequences in terms of greenhouse gas emissions and loss of ecosystem services. However, the impact of armed conflict on forests is complex and may simultaneously lead to positive and negative environmental outcomes, i.e. forest regrowth and deforestation, in different regions even within a country. We investigate the impact that armed conflict exerted over forest dynamics at different spatial scales in Colombia and for the global tropics during the period 1992-2015. Through the analysis of its internally displaced population (departures) our results suggest that, albeit finding forest regrowth in some municipalities, the Colombian conflict predominantly exerted a negative impact on its forests. A further examination of georeferenced fighting locations in Colombia and across the globe shows that conflict areas were 8 and 4 times more likely to undergo deforestation, respectively, in the following years in relation to average deforestation rates. This study represents a municipality level, long-term spatial analysis of the diverging effects the Colombian conflict exerted over its forest dynamics over two distinct periods of increasing and decreasing conflict intensity. Moreover, it presents the first quantified estimate of conflict's negative impact on forest ecosystems across the globe. The relationship between armed conflict and land use change is of global relevance given the recent increase of armed conflicts across the world and the importance of a possible exacerbation of armed conflicts and migration as climate change impacts increase.},

  abstract  = {In den vergangenen Jahren ist es zu einer dramatischen Vervielfachung der verf{\"u}gbaren Rechenzeit gekommen. Diese 'Grid Ressourcen' stehen jedoch nicht als kontinuierlicher Strom zur Verf{\"u}gung, sondern sind {\"u}ber verschiedene Maschinentypen, Plattformen und Betriebssysteme verteilt, die jeweils durch Netzwerke mit fluktuierender Bandbreite verbunden sind. Es wird f{\"u}r Wissenschaftler zunehmend schwieriger, die verf{\"u}gbaren Ressourcen f{\"u}r ihre Anwendungen zu nutzen. Wir glauben, dass intelligente, selbstbestimmende Applikationen in der Lage sein sollten, ihre Ressourcen in einer dynamischen und heterogenen Umgebung selbst zu w{\"a}hlen: Migrierende Applikationen suchen eine neue Ressource, wenn die alte aufgebraucht ist. 'Spawning'-Anwendungen lassen Algorithmen auf externen Maschinen laufen, um die Hauptanwendung zu beschleunigen. Applikationen werden neu gestartet, sobald ein Absturz endeckt wird. Alle diese Verfahren k{\"o}nnen ohne menschliche Interaktion erfolgen. Eine verteilte Rechenumgebung besitzt eine nat{\"u}rliche Unverl{\"a}sslichkeit. Jede Applikation, die mit einer solchen Umgebung interagiert, muss auf die gest{\"o}rten Komponenten reagieren k{\"o}nnen: schlechte Netzwerkverbindung, abst{\"u}rzende Maschinen, fehlerhafte Software. Wir konstruieren eine verl{\"a}ssliche Serviceinfrastruktur, indem wir der Serviceumgebung eine 'Peer-to-Peer'-Topology aufpr{\"a}gen. Diese "Grid Peer Service" Infrastruktur beinhaltet Services wie Migration und Spawning, als auch Services zum Starten von Applikationen, zur Datei{\"u}bertragung und Auswahl von Rechenressourcen. Sie benutzt existierende Gridtechnologie wo immer m{\"o}glich, um ihre Aufgabe durchzuf{\"u}hren. Ein Applikations-Information- Server arbeitet als generische Registratur f{\"u}r alle Teilnehmer in der Serviceumgebung.

Er transferiert den Statusfile des Applikation zu der neuen Maschine und startet die Applikation neu. Obwohl das umgebende Ressourcensubstrat nicht kontinuierlich ist, k{\"o}nnen wir kontinuierliche Berechnungen auf Grids ausf{\"u}hren, indem wir die Applikation migrieren.

  abstract  = {The interaction between endothelial cells and pericytes is crucial for the stabilization of newly formed vessels in angiogenesis. The comprehension of the mechanisms regulating peiicyte recruitment might open therapeutical perspectives on vascular-related pathologies. Sphingosine 1phosphate (SIP) is a bioactive sphingolipid that derives from sphingomyelin catabolism and regulates biological functions in cell survival, proliferation, and differentiation. In this study, we aimed to identify the role of SIP axis in the intercellular communication between human mesenchymal progenitor mesoangioblasts (MAB) and endothelial cells (human microvascular endothelial cells (HMVEC)) in the formation of capillary-like structures. We demonstrated that the SIP biosynthetic pathway brought about by sphingosine kinases (SK) SKI and SK2 as well as spinster homolog 2 (SPNS2) transporter in H-MVEC is crucial for MAB migration measured by Boyden chambers and for the formation and stabilization of capillary-like structures in a 3D Matrigel culture. Moreover, the conditioned medium (CM) harvested from HMVEC, where SKI, 5K2, and SPNS2 were down-regulated, exerted a significantly diminished effect on MAB capillary morphogenesis and migration. Notably, we demonstrated that S I Pi and Si p3 receptors were positively involved in CM-induced capillary-like formation and migration, while S I P2 exerted a negative role on CM-induced migratory action of MAB. Finally, SK inhibition as well as MAB SlPi and S1P3 down-regulation impaired HMVEC-MAB cross-talk significantly reducing in vivo angiogenesis evaluated by Matrigel plug assay. These findings individuate novel targets for the employment of MAB in vascular-related pathologic conditions.},

  abstract  = {Ein transversales St{\"o}rungssystem im Nahen Osten, die Dead Sea Transform (DST), trennt die Arabische Platte von der Sinai-Mikroplatte und erstreckt sich von S{\"u}den nach Norden vom Extensionsgebiet im Roten Meer {\"u}ber das Tote Meer bis zur Taurus-Zagros Kollisionszone. Die sinistrale DST bildete sich im Mioz{\"a}n vor etwa 17 Ma und steht mit dem Aufbrechen des Afro-Arabischen Kontinents in Verbindung. Das Untersuchungsgebiet liegt im Arava Tal zwischen Totem und Rotem Meer, mittig {\"u}ber der Arava St{\"o}rung (Arava Fault, AF), die hier den Hauptast der DST bildet. Eine Reihe seismischer Experimente, aufgebaut aus k{\"u}nstlichen Quellen, linearen Profilen {\"u}ber die St{\"o}rung und entsprechend entworfenen Empf{\"a}nger-Arrays, zeigt die Untergrundstruktur in der Umgebung der AF und der Verwerfungszone selbst bis in eine Tiefe von 3-4 km. Ein tomographisch bestimmtes Modell der seismischen Geschwindigkeiten von P-Wellen zeigt einen starken Kontrast nahe der AF mit niedrigeren Geschwindigkeiten auf der westlichen Seite als im Osten. Scherwellen lokaler Erdbeben liefern ein mittleres P-zu-S Geschwindigkeitsverh{\"a}ltnis und es gibt Anzeichen f{\"u}r {\"A}nderungen {\"u}ber die St{\"o}rung hinweg. Hoch aufgel{\"o}ste tomographische Geschwindigkeitsmodelle best{\"a}tigen der Verlauf der AF und stimmen gut mit der Oberfl{\"a}chengeologie {\"u}berein. Modelle des elektrischen Widerstands aus magnetotellurischen Messungen im selben Gebiet zeigen eine leitf{\"a}hige Schicht westlich der AF, schlecht leitendes Material {\"o}stlich davon und einen starken Kontrast nahe der AF, die den Fluss von Fluiden von einer Seite zur anderen zu verhindern scheint. Die Korrelation seismischer Geschwindigkeiten und elektrischer Widerst{\"a}nde erlaubt eine Charakterisierung verschiedener Lithologien im Untergrund aus deren physikalischen Eigenschaften. Die westliche Seite l{\"a}sst sich durch eine geschichtete Struktur beschreiben, wogegen die {\"o}stliche Seite eher einheitlich erscheint. Die senkrechte Grenze zwischen den westlichen Einheiten und der {\"o}stlichen scheint gegen{\"u}ber der Oberfl{\"a}chenauspr{\"a}gung der AF nach Osten verschoben zu sein. Eine Modellierung von seismischen Reflexionen an einer St{\"o}rung deutet an, dass die Grenze zwischen niedrigen und hohen Geschwindigkeiten eher scharf ist, sich aber durch eine raue Oberfl{\"a}che auf der L{\"a}ngenskala einiger hundert Meter auszeichnen kann, was die Streuung seismischer Wellen beg{\"u}nstigte. Das verwendete Abbildungsverfahren (Migrationsverfahren) f{\"u}r seismische Streuk{\"o}rper basiert auf Array Beamforming und der Koh{\"a}renzanalyse P-zu-P gestreuter seismischer Phasen. Eine sorgf{\"a}ltige Bestimmung der Aufl{\"o}sung sichert zuverl{\"a}ssige Abbildungsergebnisse. Die niedrigen Geschwindigkeiten im Westen entsprechen der jungen sediment{\"a}ren F{\"u}llung im Arava Tal, und die hohen Geschwindigkeiten stehen mit den dortigen pr{\"a}kambrischen Magmatiten in Verbindung. Eine 7 km lange Zone seismischer Streuung (Reflektor) ist gegen{\"u}ber der an der Oberfl{\"a}che sichtbaren AF um 1 km nach Osten verschoben und l{\"a}sst sich im Tiefenbereich von 1 km bis 4 km abbilden. Dieser Reflektor markiert die Grenze zwischen zwei lithologischen Bl{\"o}cken, die vermutlich wegen des horizontalen Versatzes entlang der DST nebeneinander zu liegen kamen. Diese Interpretation als lithologische Grenze wird durch die gemeinsame Auswertung der seismischen und magnetotellurischen Modelle gest{\"u}tzt. Die Grenze ist m{\"o}glicherweise ein Ast der AF, der versetzt gegen{\"u}ber des heutigen, aktiven Asts verl{\"a}uft. Der Gesamtversatz der DST k{\"o}nnte r{\"a}umlich und zeitlich auf diese beiden {\"A}ste und m{\"o}glicherweise auch auf andere St{\"o}rungen in dem Gebiet verteilt sein.},

  abstract  = {Already at the beginning of the fifties on the initiative of Italy, negotiations began between the Italian and German governments for the recruitment of migrant-workers, which ended in 1955 with a bilateral agreement between the two countries. Through this recruitment policy and because of the labour-market (Industry and Building) the Italian migration was composed prevalently of men. Female immigration happened in the setting of family reunification and less as an independent movement project. After years of stagnation of italian emigration in the eighties it may also be noted that, since the early nineties, there has been a revival of immigration to Germany. This and modernisation processes in Italy changed the gender composition of the Italian immigration flow to Germany: the distance between male and female immigration is decreasing. A peculiarity of the Italians in Germany is the low occupational participation of women in comparison with other women from EU countries. However, we could observe regional differences, which depend on the migration typologies and the dominating economic structure in the areas. The paper will analyse this different aspects (immigration-processes, migrant-typologies and labour-market participation) by female Italian migrants.},

  abstract  = {Immigration constitutes a dynamic policy field with - often quite unpredictable - dynamics. This is based on immigration constituting a 'wicked problem' meaning that it is characterized by uncertainty, ambiguity and complexity. Due to the dynamics in the policy field, expectations towards public administrations often change. Following neo-institutionalist theory, public administrations depend on meeting the expectations in the organizational field in order to maintain legitimacy as the basis for, e.g., resources and compliance of stakeholders. With the dynamics in the policy field, expectations might change and public administrations consequently need to adapt in order to maintain or repair the then threatened legitimacy. If their organizational legitimacy is threatened by a perception of structures and processes being inadequate for changed expectations, an 'institutional crisis' unfolds. However, we know little about ministerial bureaucracies' structural reactions to such crucial momentums and how this effects the quest for coordination within policy-making. Overall, the dissertation thus links to both policy analysis and public administration research and consists of five publications. It asks: How do structures in ministerial bureaucracies change in the context of institutional crises? And what effect do these changes have on ministerial coordination? The dissertation hereby focusses on the above described dynamic policy field of immigration in Germany in the period from 2005 to 2017 and pursues three objectives: 1) to identify the context and impulse for changes in the structures of ministerial bureaucracies, 2) to describe respective changes with regard to their organizational structures, and 3) to identify their effect on coordination. It hereby compares and contrasts institutional crises by incremental change and shock as well as changes and effects at federal and L{\"a}nder level which allows a comprehensive answer to both of the research questions. Theoretically, the dissertation follows neo-institutionalist theory with a particular focus on changes in organizational structures, coordination and crisis management. Methodologically, it follows a comparative design. Each article (except for the literature review), focusses on ministerial bureaucracies at one governmental level (federal or L{\"a}nder) and on an institutional crisis induced by either an incremental process or a shock. Thus, responses and effects can be compared and contrasted across impulses for institutional crises and governmental levels. Overall, the dissertation follows a mixed methods approach with a majority of qualitative single and small-n case studies based on document analysis and semi-structured interviews. Additionally, two articles use quantitative methods as they best suited the respective research question. The rather explorative nature of these two articles however fits to the overall interpretivist approach of the dissertation. Overall, the dissertation's core argument is: Within the investigation period, varying dynamics and thus impulses for institutional crises took place in the German policy field of immigration. Respectively, expectations by stakeholders on how the politico-administrative system should address the policy problem changed. Ministerial administrations at both the federal and L{\"a}nder level adapted to these expectations in order to maintain, or regain respectively, organizational legitimacy. The administration hereby referred to well-known recipes of structural changes. Institutional crises do not constitute fields of experimentation. The new structures had an immediate effect on ministerial coordination, with respect to both the horizontal and vertical dimension. Yet, they did not mean a comprehensive change of the system in place. The dissertation thus challenges the idea of the toppling effect of crises and rather shows that adaptability and persistence of public administrations constitute two sides of the same coin.},

  school      = {Universit{\"a}t Potsdam},
  pages     = {127},
  year      = {2020},
  abstract  = {One of the tremendous discoveries by the Cassini spacecraft has been the detection of propeller structures in Saturn's A ring. Although the generating moonlet is too small to be resolved by the cameras aboard Cassini, its produced density structure within the rings, caused by its gravity can be well observed. The largest observed propeller is called Bl{\´e}riot and has an azimuthal extent over several thousand kilometers. Thanks to its large size, Bl{\´e}riot could be identified in different images over a time span of over 10 years, allowing the reconstruction of its orbital evolution. It turns out that Bl{\´e}riot deviates considerably from its expected Keplerian orbit in azimuthal direction by several thousand kilometers. This excess motion can be well reconstructed by a superposition of three harmonics, and therefore resembles the typical fingerprint of a resonantly perturbed body. This PhD thesis is directed to the excess motion of Bl{\´e}riot. Resonant perturbations are a known for some of the outer satellites of Saturn. Thus, in the first part of this thesis, we seek for suiting resonance candidates nearby the propeller, which might explain the observed periods and amplitudes. In numeric simulations, we show that indeed resonances by Prometheus, Pandora and Mimas can explain the libration periods in good agreement, but not the amplitudes. The amplitude problem is solved by the introduction of a propeller-moonlet interaction model, where we assume a broken symmetry of the propeller by a small displacement of the moonlet. This results in a librating motion the moonlet around the propeller's symmetry center due to the non-vanishing accelerations. The retardation of the reaction of the propeller structure to the motion of the moonlet causes the propeller to become asymmetric. Hydrodynamic simulations to test our analytical model confirm our predictions. In the second part of this thesis, we consider a stochastic migration of the moonlet, which is an alternative hypothesis to explain the observed excess motion of Bl{\´e}riot. The mean-longitude is a time-integrated quantity and thus introduces a correlation between the independent kicks of a random walk, smoothing the noise and thus makes the residual look similar to the observed one for Bl{\´e}riot. We apply a diagonalization test to decorrelated the observed residuals for the propellers Bl{\´e}riot and Earhart and the ring-moon Daphnis. It turns out that the decorrelated distributions do not strictly follow the expected Gaussian distribution. The decorrelation method fails to distinguish a correlated random walk from a noisy libration and thus we provide an alternative study. Assuming the three-harmonic fit to be a valid representation of the excess motion for Bl{\´e}riot, independently from its origin, we test the likelihood that this excess motion can be created by a random walk. It turns out that a non-correlated and correlated random walk is unlikely to explain the observed excess motion.},

  abstract  = {In response to mounting evidence on the dangers of irregular migration from Africa to Europe, the number of information campaigns which aim to raise awareness about the potential risks has rapidly increased. Governments, international organizations and civil society organizations implement a variety of campaigns to counter the spread of misinformation accelerated by smuggling and trafficking networks. The evidence on the effects of such information interventions on potential migrants remains limited and largely anecdotal. More generally, the role of risk perceptions in the decision-making process of potential irregular migrants is rarely explicitly tested, despite the fact that the concept of risk pervades conventional migration models, particularly in the field of economics. We address this gap by assessing the effects of a peer-to-peer information intervention on the perceptions, knowledge and intentions of potential migrants in Dakar, Senegal, using a randomized controlled trial design. The results show that - three months after the intervention - peer-to-peer information events increase potential migrants' subjective information levels, raise risk awareness, and reduce intentions to migrate irregularly. We find no substantial effects on factual migration knowledge. We discuss how the effects may be driven by the trust and identification-enhancing nature of peer-to-peer communication. <br /> (c) 2021 Elsevier Ltd. All rights reserved.},

  abstract  = {While estimated numbers of past and future climate migrants are alarming, the growing empirical evidence suggests that the association between adverse climate-related events and migration is not universally positive. This dissertation seeks to advance our understanding of when and how climate migration emerges by analyzing heterogeneous climatic influences on migration in low- and middle-income countries. To this end, it draws on established economic theories of migration, datasets from physical and social sciences, causal inference techniques and approaches from systematic literature review. In three of its five chapters, I estimate causal effects of processes of climate change on inequality and migration in India and Sub-Saharan Africa. By employing interaction terms and by analyzing sub-samples of data, I explore how these relationships differ for various segments of the population. In the remaining two chapters, I present two systematic literature reviews. First, I undertake a comprehensive meta-regression analysis of the econometric climate migration literature to summarize general climate migration patterns and explain the conflicting findings. Second, motivated by the broad range of approaches in the field, I examine the literature from a methodological perspective to provide best practice guidelines for studying climate migration empirically. Overall, the evidence from this dissertation shows that climatic influences on human migration are highly heterogeneous. Whether adverse climate-related impacts materialize in migration depends on the socio-economic characteristics of the individual households, such as wealth, level of education, agricultural dependence or access to adaptation technologies and insurance. For instance, I show that while adverse climatic shocks are generally associated with an increase in migration in rural India, they reduce migration in the agricultural context of Sub-Saharan Africa, where the average wealth levels are much lower so that households largely cannot afford the upfront costs of moving. I find that unlike local climatic shocks which primarily enhance internal migration to cities and hence accelerate urbanization, shocks transmitted via agricultural producer prices increase migration to neighboring countries, likely due to the simultaneous decrease in real income in nearby urban areas. These findings advance our current understanding by showing when and how economic agents respond to climatic events, thus providing explicit contexts and mechanisms of climate change effects on migration in the future. The resulting collection of findings can guide policy interventions to avoid or mitigate any present and future welfare losses from climate change-related migration choices.},
