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.

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.}, language = {en} } @article{HeimSchroederEccardetal.2016, author = {Heim, Olga and Schr{\"o}der, Assja and Eccard, Jana and Jung, Kirsten and Voigt, Christian C.}, title = {Seasonal activity patterns of European bats above intensively used farmland}, series = {The astrophysical journal : an international review of spectroscopy and astronomical physics ; Part 2, Letters}, volume = {233}, journal = {The astrophysical journal : an international review of spectroscopy and astronomical physics ; Part 2, Letters}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0167-8809}, doi = {10.1016/j.agee.2016.09.002}, pages = {130 -- 139}, year = {2016}, 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.

Das ist z.B. dann der Fall, wenn bestimmte Begriffe verwendet werden, obwohl eine Kontextrelevanz nicht unbedingt vorliegt. Einige ethnische Bezeichnungen werden dabei h{\"a}ufiger verwendet als andere, trotz vergleichbarer Kontextrelevanz: „t{\"u}rkische/arabische Kinder" aber nicht „englische/spanische Kinder" (Wiese 2012), „Deutsch-T{\"u}rke" Mesut {\"O}zil aber nicht „Deutsch-Tunesier" Sami Khedira. Erst die Bezeichnungen schaffen hier die Subjekte. Die besondere Auszeichnung macht es in der Folge m{\"o}glich, dass ihnen Eigenschaften zugeschrieben werden (do Mar Castro Varela/Dhawan 2004). Aus Studien geht hervor, dass Ethnisierung mit Unterschichtung (Hormel 2007) in Verbindung gebracht wird und Begriffe wie „Migrant" mit negativen Eigenschaften (Scarvagliere/Zech 2013). Durch die Auszeichnung von Abweichungen von dem von der Mehrheit definierten unmarkierten Normalfall wird eine Differenzordnung (Mecheril/Melter 2012) hergestellt, die das vermeintliche Anders-Sein ins Zentrum der Aufmerksamkeit r{\"u}ckt. Folgen sind Abwertung bestimmter (Erst-)Sprachen, Unterwerfung durch Beschreibungspraxen und Restriktionen auf dem Feld der Repr{\"a}sentation (Broden/Mecheril 2007). Ausgehend von diesen {\"U}berlegungen wird in der Arbeit „Ethnizit{\"a}t" diskutiert, worauf viele dieser Bezeichnungen rekurrieren. Barth (1969, 1994) stellt fest, dass Ethnizit{\"a}t der Abgrenzung dient und Zugeh{\"o}rigkeit zu ethnische Gruppen durch kategoriale Selbst- und Fremdzuschreibungen bestimmt wird. Brubaker (2004) folgert daher, dass „Gruppen" nur in Form von Vorstellungen existieren, die Individuen davon haben und diese Subjektivit{\"a}t zu unterschiedlichen Konstruktionen ethnischer Identit{\"a}t f{\"u}hrt. Dementsprechend k{\"o}nnen auch „multiple ethnische Identit{\"a}ten" (Keupp 2002) und „Hybridit{\"a}ten" (Foroutan 2013) das Ergebnis der individuellen Konstruktion sein, ohne dass diese Formen gemeinhin akzeptierte Bezeichnungen darstellen. Um die individuelle Entstehung ethnischer Identit{\"a}t nachvollziehen zu k{\"o}nnen, werden in der Arbeit Spracherwerbsgeschichten analysiert, da verschiedene Studien nahelegen, dass das Sprechen einer Sprache in engem Zusammenhang zur Ethnizit{\"a}t steht. Ohm (2008) zeigt, dass Zweitsprachenerwerb mit Identit{\"a}tsprozessen in einem wechselseitigen Bedingungsverh{\"a}ltnis steht. Giles/Bourhis/Taylor (1977: 326) zeigen anhand von Untersuchungen in mehrsprachigen Gebieten wie Quebec und Wales, dass Sprache enger mit ethnischer Identit{\"a}t verbunden ist als Nationalit{\"a}t oder „Kultur". Rosenberg (2015) f{\"u}hrt am Beispiel der ehemaligen UdSSR auf, dass das Sprechen einer Sprache gleichbedeutend mit dem Zugeh{\"o}rigkeit zu einer ethnischen „Gruppe" war. Sprache greift auch als Ausschlusskriterium: Nur wer eine Sprache gut spricht, darf die damit verbundene Identit{\"a}t in Anspruch nehmen (Schroeder/Dollnick, 2013: 104). Mithilfe der Methode des narrativen Interviews k{\"o}nnen Spracherwerbsgeschichten produziert, und individuelle kognitive Perspektiven und gesellschaftliche Prozesse aufgedeckt werden. In der Analyse k{\"o}nnen vier Wege der Entstehung ethnischer Identit{\"a}t unterschieden werden: I. Ethnizit{\"a}t als prim{\"a}re und dauerhafte Dimension, II. Multiple ethnische Identit{\"a}t, III. Unmarkierte ethnische Identit{\"a}t, IV. Selbstbestimmtheit. So kommt die Untersuchung zu dem Schluss, dass Ethnische Identit{\"a}t bei „Menschen mit t{\"u}rkischem Migrationshintergrund" durch individuelle Erfahrungen entsteht, sich ver{\"a}ndern und Mehrfachzugeh{\"o}rigkeiten oder Hybridit{\"a}ten zulassen kann.

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.

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.}, language = {en} } @article{KlugeRappMehranetal.2019, author = {Kluge, Ulrike and Rapp, Michael A. and Mehran, Nassim and Abi Jumaa, Jinan and Aichberger, Marion Christina}, title = {Poverty, migration and mental health}, series = {Der Nervenarzt : Organ der Deutschen Gesellschaft f{\"u}r Psychiatrie, Psychotherapie und Nervenheilkunde ; Mitteilungsblatt der Deutschen Gesellschaft f{\"u}r Neurologie}, volume = {90}, journal = {Der Nervenarzt : Organ der Deutschen Gesellschaft f{\"u}r Psychiatrie, Psychotherapie und Nervenheilkunde ; Mitteilungsblatt der Deutschen Gesellschaft f{\"u}r Neurologie}, number = {11}, publisher = {Springer}, address = {New York}, issn = {0028-2804}, doi = {10.1007/s00115-019-00790-2}, pages = {1103 -- 1108}, year = {2019}, abstract = {Poverty and social exclusion are closely related to an increased risk for the deterioration of mental health.

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.}, language = {en} } @phdthesis{Radtke2020, author = {Radtke, Ina}, title = {Organizing immigration}, school = {Universit{\"a}t Potsdam}, pages = {174}, year = {2020}, 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.}, language = {en} }
