  abstract  = {We suggest several ideas which when combined could lead to a new mechanism for long-term pulsations of very hot and luminous stars. These involve the interplay between convection, radiation, atmospheric clumping and winds, which collectively feed back to stellar expansion and contraction.

  abstract  = {Methanhydrate sind besonders in Verbindung mit den steigenden Weltmarktpreisen f{\"u}r {\"O}l und Gas in den vergangenen Jahren mehr und mehr in den Fokus der Energiewirtschaft geraten, was zu einer starken Zunahme der angewandten Forschungsprojekte auf diesem Gebiet f{\"u}hrte. Da Methanhydrat nur unter hohem Druck und niedrigen Temperaturen stabil ist, ist die Gewinnung nat{\"u}rlicher Proben f{\"u}r Laboruntersuchungen technisch sehr aufwendig und vor allem teuer. Zur Charakterisierung der Eigenschaften hydratf{\"u}hrender Reservoire ist man h{\"a}ufig auf die Herstellung synthetischer Proben angewiesen. Die Eigenschaften der synthetisierten Proben sind dabei abh{\"a}ngig von der Herstellungsmethode und man ist noch immer auf der Suche nach Verfahren, mit denen sich m{\"o}glichst „naturnahe" Proben mit vertretbarem Aufwand erzeugen lassen. In der vorliegenden Arbeit wurde eine neue, relativ schnell durchf{\"u}hrbare Methode getestet, die im Porenraum von Sedimenten schwimmende bzw. gef{\"u}gest{\"u}tzende Hydrate bildet, wie sie in der Natur vorkommen. Gleichzeitig erzeugt sie eine gleichm{\"a}ßige Verteilung des Hydrats {\"u}ber die Probe und bietet gute Kontrolle {\"u}ber den Hydratgehalt. Sie funktioniert wie folgt: Eine mit einer KCl-L{\"o}sung ges{\"a}ttigte Sedimentprobe wird zu einem bestimmten Teil ausgefroren und das {\"u}brige Wasser mit Methan verdr{\"a}ngt. Durch Anlegen eines Methandrucks im Stabilit{\"a}tsbereich wird das Eis zu Methanhydrat umgesetzt. Im Anschluss wird die Probe erneut mit einer KCl-L{\"o}sung ges{\"a}ttigt. Anhand seismischer Messungen konnte best{\"a}tigt werden, dass Hydrat mit dem gew{\"u}nschten Hydrathabitus erzeugt wurde. Des Weiteren wurde gezeigt, dass die eishaltigen Proben aufgrund {\"a}hnlicher physikalischer Eigenschaften bereits vor der Umsetzung des Eises zu Methanhydrat als N{\"a}herung f{\"u}r Proben mit Porenraumhydrat verwendet werden k{\"o}nnen.},

  abstract  = {It is well established in language acquisition research that monolingual children and adult second language learners misinterpret sentences with the universal quantifier every and make quantifier-spreading errors that are attributed to a preference for a match in number between two sets of objects. The present Visual World eye-tracking study tested bilingual heritage Russian-English adults and investigated how they interpret of sentences like Every alligator lies in a bathtub in both languages. Participants performed a sentence-picture verification task while their eye movements were recorded. Pictures showed three pairs of alligators in bathtubs and two extra objects: elephants (Control condition), bathtubs (Overexhaustive condition), or alligators (Underexhaustive condition). Monolingual adults performed at ceiling in all conditions. Heritage language (HL) adults made 20\% q-spreading errors, but only in the Overexhaustive condition, and when they made an error they spent more time looking at the two extra bathtubs during the Verb region. We attribute q-spreading in HL speakers to cognitive overload caused by the necessity to integrate conflicting sources of information, i.e. the spoken sentences in their weaker, heritage, language and attention-demanding visual context, that differed with respect to referential salience.},

By utilizing the second-order NLO process of second harmonic generation (SHG), supported by density-functional theory and correlated wave function method calculations, we demonstrate that the photochromic interface provides the necessary prerequisites en route towards possible future technical applications: we find a high NLO contrast on the order of 16\% between the switching states. These are furthermore accessible reversibly and with high efficiencies in terms of cross sections on the order of 10-18 cm2 for both photoisomerization reactions, i.e., drivable by means of low-power LED light sources. Finally, both photostationary states (PSSs) are thermally stable at ambient conditions.},

Aufgrund des Zusammenwirkens der funktional-semantischen Kategorien Temporalit{\"a}t, Aspektualit{\"a}t und Modalit{\"a}t wird der Perfektgebrauch hinsichtlich dieser Kategorien analysiert. Es wird angenommen, dass sich das Perfekt im Spanischen und Deutschen nicht nur in Bezug auf seine temporalen und aspektuellen Werte, sondern auch hinsichtlich seiner modal-evidentiellen Werte und Ausdrucksweisen unterscheidet. Ziel dieses Beitrags ist es, die spezifischen temporalen und aspektuellen Bedeutungen dieses Vergangenheitstempus in der jeweiligen Sprache herauszustellen, kontrastiv zu betrachten und zu zeigen, inwiefern Perfektformen als Evidentialit{\"a}tsmarker fungieren k{\"o}nnen. Der modal-evidentiellen Bedeutung des Perfekts kommt in dieser Arbeit eine zentrale Rolle zu, da insbesondere hinsichtlich der deutschen Perfekt-Konstruktionen noch wenige Forschungsans{\"a}tze vorliegen. Die modalen und evidentiellen Bedeutungen des Perfekts werden in beiden Sprachen in der Schriftsprache unter Einbezug der Erkenntnisse der RAE (2009), Wachtmeister-Berm{\´u}dez (2005) und Diewald (2011) diskutiert und anhand von Beispielen aus spanischen und deutschen Pressetexten des CREA sowie der Zeit Online und S{\"u}ddeutsche Zeitung belegt. Als Ergebnis dieser Untersuchung l{\"a}sst sich feststellen, dass das Perfekt in beiden Sprachen als Evidentialit{\"a}tsmarker dienen und verschiedene Arten von Evidenz markieren kann. Die Relevanz der kontrastiven Betrachtung kommt in zwei signifikanten Forschungsbereichen zum Tragen: zum Einen bei der {\"U}bersetzung, da die temporalen, aspektuellen und modal-evidentiellen Werte des Perfekts in der jeweiligen Sprache beachtet werden m{\"u}ssen und zum Anderen in der Fremdsprachendidaktik, da das Perfekt verschiedene Stellenwerte in den einzelnen Verbalsystemen einnimmt.},

  abstract  = {This study presents the development of 1D and 2D Surface Evolution Codes (SECs) and their coupling to any lithospheric-scale (thermo-)mechanical code with a quadrilateral structured surface mesh. Both SECs involve diffusion as approach for hillslope processes and the stream power law to reflect riverbed incision. The 1D SEC settles sediment that was produced by fluvial incision in the appropriate minimum, while the supply-limited 2D SEC DANSER uses a fast filling algorithm to model sedimantation. It is based on a cellular automaton. A slope-dependent factor in the sediment flux extends the diffusion equation to nonlinear diffusion. The discharge accumulation is achieved with the D8-algorithm and an improved drainage accumulation routine. Lateral incision enhances the incision's modelling. Following empirical laws, it incises channels of several cells width. The coupling method enables different temporal and spatial resolutions of the SEC and the thermo-mechanical code. It transfers vertical as well as horizontal displacements to the surface model. A weighted smoothing of the 3D surface displacements is implemented. The smoothed displacement vectors transmit the deformation by bilinear interpolation to the surface model. These interpolation methods ensure mass conservation in both directions and prevent the two surfaces from drifting apart. The presented applications refer to the evolution of the Pamir orogen. A calibration of DANSER's parameters with geomorphological data and a DEM as initial topography highlights the advantage of lateral incision. Preserving the channel width and reflecting incision peaks in narrow channels, this closes the huge gap between current orogen-scale incision models and observed topographies. River capturing models in a system of fault-bounded block rotations reaffirm the importance of the lateral incision routine for capturing events with channel initiation. The models show a low probability of river capturings with large deflection angles. While the probability of river capturing is directly depending on the uplift rate, the erodibility inside of a dip-slip fault speeds up headward erosion along the fault: The model's capturing speed increases within a fault. Coupling DANSER with the thermo-mechanical code SLIM 3D emphasizes the versatility of the SEC. While DANSER has minor influence on the lithospheric evolution of an indenter model, the brittle surface deformation is strongly affected by its sedimentation, widening a basin in between two forming orogens and also the southern part of the southern orogen to south, east and west.},

Nur in einem geringen Teil der westlichen Bev{\"o}lkerung wird der Daidzein-Metabolit Equol durch spezifische Darmbakterien gebildet. Ein isoliertes Equol-produzierendes Bakterium des menschlichen Darmtrakts ist Slackia isoflavoniconvertens. Anhand dieser Spezies sollten die bislang unbekannten, an der Umsetzung von Daidzein und Genistein beteiligten Enzyme identifiziert und charakterisiert werden. Fermentationsexperimente mit S. isoflavoniconvertens zeigten, dass die Gene der Daidzein und Genistein-umsetzenden Enzyme nicht konstitutiv exprimiert werden, sondern induziert werden m{\"u}ssen. Mit Hilfe der zweidimensionalen differentiellen Gelelektrophorese wurden sechs Proteine detektiert, welche in einer S. isoflavoniconvertens-Kultur in Anwesenheit von Daidzein induziert wurden. Auf Grundlage einzelner Peptidsequenzen erfolgte die Sequenzierung eines Genkomplexes mit den in gleicher Orientierung angeordneten Genen der durch Daidzein induzierten Proteine. Sequenzvergleiche identifizierten zudem {\"a}quivalente Genprodukte zu den Proteinen von S. isoflavoniconvertens in anderen Equolproduzierenden Bakterien. Nach der heterologen Expression in Escherichia coli wurden drei dieser Gene durch enzymatische Aktivit{\"a}tstests als Daidzein-Reduktase (DZNR), Dihydrodaidzein-Reduktase (DHDR) und Tetrahydrodaidzein-Reduktase (THDR) identifiziert. Die Kombination der E. coli-Zellextrakte f{\"u}hrte zur vollst{\"a}ndigen Umsetzung von Daidzein {\"u}ber Dihydrodaidzein zu Equol. Neben Daidzein setzte die DZNR auch Genistein zu Dihydrogenistein um. Dies erfolgte mit einer gr{\"o}ßeren Umsatzgeschwindigkeit im Vergleich zur Reduktion von Daidzein zu Dihydrodaidzein. Enzymatische Aktivit{\"a}tstests mit dem Zellextrakt von S. isoflavoniconvertens zeigten ebenfalls eine schnellere Umsetzung von Genistein. Die Kombination der rekombinanten DHDR und THDR f{\"u}hrte zur Umsetzung von Dihydrodaidzein zu Equol. Der korrespondierende Metabolit 5-Hydroxyequol konnte als Endprodukt des Genistein-Metabolismus nicht detektiert werden. Zur Reinigung der drei identifizierten Reduktasen wurden diese genetisch an ein Strep-tag fusioniert und mittels Affinit{\"a}tschromatographie gereinigt. Die {\"u}brigen durch Daidzein induzierten Proteine IfcA, IfcBC und IfcE wurden ebenfalls in E. coli exprimiert und als Strep-Fusionsproteine gereinigt. Vergleichende Aktivit{\"a}tstests identifizierten das induzierte Protein IfcA als Dihydrodaidzein-Racemase. Diese katalysierte die Umsetzung des (R)- und (S)-Enantiomers von Dihydrodaidzein und Dihydrogenistein zum korrespondierenden Racemat. Neben dem Elektronentransfer-Flavoprotein IfcBC wurden auch die THDR, DZNR und IfcE als FAD-haltige Flavoproteine identifiziert. Zudem handelte es sich bei IfcE um ein Eisen-Schwefel-Protein. Nach Induktion der f{\"u}r die Daidzein-Umsetzung kodierenden Gene wurden mehrere verschieden lange mRNA-Transkripte gebildet. Dies zeigte, dass die Transkription des durch Daidzein induzierten Genkomplexes in S. isoflavoniconvertens nicht in Form eines einzelnen Operonsystems erfolgte. Auf Grundlage der identifizierten Daidzein-umsetzenden Enzyme kann der Mechanismus der bakteriellen Umsetzung von Isoflavonen durch S. isoflavoniconvertens eingehend erforscht werden. Die ermittelten Gensequenzen der durch Daidzein induzierten Proteine sowie die korrespondierenden Gene weiterer Equol-produzierender Bakterien bieten zudem die M{\"o}glichkeit der mikrobiellen Metagenomanalyse im humanen Darmtrakt.},

  abstract  = {This paper presents an overview of the linguistic analyses developed in the MULTILIT project and the processing of the oral and written texts collected. The project investigates the language abilities of multilingual children and adolescents, in particular, those who have Turkish and/or Kurdish as a mother tongue. A further aim of the project is to examine from a psycholinguistic and sociolinguistic perspective the extent to which competence in academic registers is achieved on the basis of the languages spoken by the children, including the language(s) spoken at the home, the language of the country of residence and the first foreign language. To be able to examine these questions using corpus linguistic parameters, we created categories of analysis in MULTILIT. The data collection comprises texts from bilingual and monolingual children and adolescents in Germany in their first language Turkish, their second language German und their foreign language English. Pupils aged between nine and twenty years of age produced monologue oral and written texts in the two genres of narrative and discursive. On the basis of these samples, we examine linguistic features such as lexical expression (lexical density, lexical diversity), syntactic complexity (syntactic and discursive packaging) as well as phonology in the oral texts and orthography in the written texts, with the aim of investigating the pupils' growing mastery of these features in academic and informal registers. To this end the raw data have been transcribed by the use of transcription conventions developed especially for the needs of the MULTILIT data. They are based on the commonly used HIAT and GAT transcription conventions and supplemented with conventions that provide additional information such as features at the graphic level. The categories of analysis comprise a large number of linguistic categories such as word classes, syntax, noun phrase complexity, complex verbal morphology, direct speech and text structures. We also annotate errors and norm deviations at a wide range of levels (orthographic, morphological, lexical, syntactic and textual). In view of the different language systems, these criteria are considered separately for all languages investigated in the project.},

Wie wurde das Instrument Zielsteuerung bzw. Zielvereinbarung im {\"o}ffentlichen Sektor eingef{\"u}hrt und in die Managementroutinen integriert? 2. Welche Faktoren f{\"u}hren zu einer Integration der Zielsteuerung in die Managementroutinen? 3. Welche Empfehlungen f{\"u}r die Praxis lassen sich daraus ableiten? Dazu wurde ein Landesbetrieb in Brandenburg detailliert untersucht und 31 Interviews mit F{\"u}hrungskr{\"a}ften der zweiten und dritten Managementebene gef{\"u}hrt. In dieser Organisation wurde im Rahmen der deutschlandweiten Reformbewegung in der {\"o}ffentlichen Verwaltung das Instrument Zielsteuerung bzw.

Als Untersuchungseinheit der m{\"o}glichen Anpassungen und Ver{\"a}nderungen wurde das Konstrukt der Managementroutinen herangezogen, welche als kollektive Handlungsmuster ganz bewusst individuelle Verhaltensweisen ausklammerten. Die Arbeit konnte eine Reihe von fr{\"u}heren Erkenntnissen best{\"a}tigen und zudem nachweisen, dass, entgegen des h{\"a}ufigen Vorurteils, Innovationen aus dem privatwirtschaftlichem Raum doch auch zu positiven Ver{\"a}nderungen in Organisationen der {\"o}ffentlichen Hand f{\"u}hren k{\"o}nnen. Es kam hier jedoch nicht zur Entwicklung neuer, sondern zu einer Anpassung der bestehenden Routinen. Auf dieser Basis konnte festgestellt werden, dass ein stufenweiser Einf{\"u}hrungsvorgang zun{\"a}chst auf der Ebene der ver{\"a}nderten Zielvorstellungen der F{\"u}hrungskr{\"a}fte zum Erfolg f{\"u}hrte. Erst nach der Anpassung auf dieser „ostentativen" Ebene kam es mit etwas Verz{\"o}gerung zu einer Ver{\"a}nderung auf der Ebene der konkreten Handlungen. Im Hinblick auf die Einflussfaktoren der Innovation konnte festgestellt werden, dass viele Aspekte der Zielsetzungstheorie nach wie vor relevant sind und instabile politische Rahmenbedingungen zu wesentlichen Einschr{\"a}nkungen der Entfaltungsm{\"o}glichkeiten der Innovation f{\"u}hren k{\"o}nnen.

Hierbei bilden F{\"a}higkeiten zur phonologischen Bewusstheit (PhB) den Schwerpunkt. Der erfolgreiche Schriftspracherwerb ist nicht nur f{\"u}r den Bildungserfolg mit den damit verbundenen beruflichen und sozio‑{\"o}konomischen Perspektiven wichtig, sondern auch f{\"u}r die aktive Teilhabe am sozialen und kulturellen Leben in unserer Gesellschaft. Die Bestandteile dieser publikationsbasierten Dissertation sind eine Monographie (Schnitzler, 2008), ein Beitrag in einem Sammelwerk (Schnitzler, 2013) sowie zwei Zeitschriftenartikel (Schnitzler, 2014, 2015). Die ersten beiden Publikationen besch{\"a}ftigen sich mit der Entwicklung der PhB sowie Zusammenh{\"a}ngen zwischen PhB und Schriftsprachfertigkeiten. Die beiden Zeitschriftenartikel besch{\"a}ftigen sich mit dem LRS‑Risiko deutschsprachiger Kinder, die im Vorschulalter aufgrund phonologischer Aussprachest{\"o}rungen (PhAS) logop{\"a}disch behandelt werden. Hierzu wurden in Schnitzler (2015) die Ergebnisse einer selbst durchgef{\"u}hrten Studie dargestellt. In dieser Studie wurden m{\"o}gliche Einfl{\"u}sse zus{\"a}tzlicher nicht‑phonologischer Symptome und der Art der phonologischen Aussprachest{\"o}rung kontrolliert. Die Ergebnisse weisen darauf hin, dass zum Schulbeginn und w{\"a}hrend der Schuleingangsphase genau beobachtet werden sollte, ob Kinder {\"u}ber altersentsprechende F{\"a}higkeiten zur PhB verf{\"u}gen und ob sie diese segmental‑phonologischen Wissensbest{\"a}nde bewusst aktivieren und beim Lesen und Schreiben effizient nutzen. Dies gilt insbesondere f{\"u}r Kinder, f{\"u}r die ein erh{\"o}htes LRS‑Risiko besteht. Verf{\"u}gen Kinder zu dieser Zeit {\"u}ber unzureichend spezifizierte phonologische Repr{\"a}sentationen, ist eine fr{\"u}hzeitige Intervention im Sinne einer Pr{\"a}vention von LRS angezeigt.},

  abstract  = {This explorative study gives a descriptive overview of what organizations do and experience when they say they practice design thinking. It looks at how the concept has been appropriated in organizations and also describes patterns of design thinking adoption. The authors use a mixed-method research design fed by two sources: questionnaire data and semi-structured personal expert interviews. The study proceeds in six parts: (1) design thinking¹s entry points into organizations; (2) understandings of the descriptor; (3) its fields of application and organizational localization; (4) its perceived impact; (5) reasons for its discontinuation or failure; and (6) attempts to measure its success. In conclusion the report challenges managers to be more conscious of their current design thinking practice. The authors suggest a co-evolution of the concept¹s introduction with innovation capability building and the respective changes in leadership approaches. It is argued that this might help in unfolding design thinking¹s hidden potentials as well as preventing unintended side-effects such as discontented teams or the dwindling authority of managers.},

  abstract  = {Die Interaktionen von komplexen Kohlenhydraten und Proteinen sind ubiquit{\"a}r. Sie spielen wichtige Rollen in vielen physiologischen Prozessen wie Zelladh{\"a}sion, Signaltransduktion sowie bei viralen Infektionen. Die molekularen Grundlagen der Interaktion sind noch nicht komplett verstanden. Ein Modellsystem f{\"u}r Kohlenhydrat-Protein-Interaktionen besteht aus Adh{\"a}sionsproteinen (Tailspikes) von Bakteriophagen, die komplexe Kohlenhydrate auf bakteriellen Oberfl{\"a}chen (O-Antigen) erkennen. Das Tailspike-Protein (TSP), das in dieser Arbeit betrachtet wurde, stammt aus dem Bakteriophagen 9NA (9NATSP). 9NATSP weist eine hohe strukturelle Homologie zum gut charakterisierten TSP des Phagen P22 (P22TSP) auf, bei einer niedriger sequenzieller {\"A}hnlichkeit. Die Substratspezifit{\"a}ten beider Tailspikes sind {\"a}hnlich mit Ausnahme der Toleranz gegen{\"u}ber den glucosylierten Formen des O-Antigens. Die Struktur der beiden Tailspikes ist bekannt, sodass sie ein geeignetes System f{\"u}r vergleichende Bindungsstudien darstellen, um die strukturellen Grundlagen f{\"u}r die Unterschiede der Spezifit{\"a}t zu untersuchen. Im Rahmen dieser Arbeit wurde der ELISA-like tailspike adsorption assay (ELITA) etabliert, um Binderpaare aus TSPs und O-Antigen zu identifizieren. Dabei wurden 9NATSP und P22TSP als Sonden eingesetzt, deren Bindung an die intakten, an die Mikrotiterplatte adsorbierten Bakterien getestet wurde. Beim Test einer Sammlung aus 44 Salmonella-St{\"a}mmen wurden St{\"a}mme identifiziert, die bindendes O-Antigen exprimieren. Gleichzeitig wurden Unterschiede in der Bindung der beiden TSPs an Salmonella-St{\"a}mme mit gleichem O-Serotyp beobachtet. Die Ergebnisse der ELITA-Messung wurden qualitativ durch eine FACS-basierte Bindungsmessung best{\"a}tigt. Zus{\"a}tzlich erm{\"o}glichte die FACS-Messung bei St{\"a}mmen, die teilweise modifizierte O-Antigene herstellen, den Anteil an Zellen mit und ohne Modifikation zu erfassen. Die Oberfl{\"a}chenplasmonresonanz (SPR)-basierten Interaktionsmessungen wurden eingesetzt, um Bindungsaffinit{\"a}ten f{\"u}r eine TSP-O-Antigen Kombination zu quantifizieren. Daf{\"u}r wurden zwei Methoden getestet, um die Oligosaccharide auf einem SPR-Chip zu immobilisieren. Zum einen wurden die enzymatisch hergestellten O-Antigenfragmente mit einem bifunktionalen Oxaminadapter derivatisiert, der eine prim{\"a}re Aminogruppe f{\"u}r die Immobilisierung bereitstellt. Ein Versuch, diese Oligosaccharidfragmente zu immobilisieren, war jedoch nicht erfolgreich. Dagegen wurde das nicht derivatisierte Polysaccharid, bestehend aus repetitivem O-Antigen und einem konservierten Kernsaccharid, erfolgreich auf einem SPR-Chip immobilisiert. Die Immobilisierung wurde durch Interaktionsmessungen mit P22TSP best{\"a}tigt. Durch die Immobilisierung des Polysaccharids sind somit quantitative SPR-Bindungsmessungen mit einem polydispersen Interaktionspartner m{\"o}glich. Eine Auswahl von Salmonella-St{\"a}mmen mit einer ausgepr{\"a}gt unterschiedlichen Bindung von 9NATSP und P22TSP im ELITA-Testsystem wurde hinsichtlich der Zusammensetzung des O-Antigens mittels HPLC, Kapillargelelektrophorese und MALDI-MS analysiert. Dabei wurden nicht-st{\"o}chiometrische Modifikationen der O-Antigene wie Acetylierung und Glucosylierung detektiert. Das Ausmaß der Glucosylierung korrelierte negativ mit der Effizienz der Bindung und des Verdaus durch die beiden TSPs, wobei der negative Effekt bei 9NATSP weniger stark ausgepr{\"a}gt war als bei P22TSP. Dies stimmt mit den Literaturdaten zu Infektivit{\"a}tsstudien mit 9NA und P22 {\"u}berein, die mit St{\"a}mmen mit vergleichbaren O-Antigenvarianten durchgef{\"u}hrt wurden. Die Korrelation zwischen der Glucosylierung und Bindungseffizienz konnte strukturell interpretiert werden. Auf Grundlage der O-Antigenanalysen sowie der Ergebnisse der ELITA- und FACS-Bindungstests wurden die Salmonella-St{\"a}mme Brancaster und Kalamu identifiziert, die ann{\"a}hernd quantitativ glucosyliertes O-Antigen exprimieren. Damit eignen sich diese St{\"a}mme f{\"u}r weiterf{\"u}hrende Studien, um die Zusammenh{\"a}nge zwischen der Spezifit{\"a}t und der Organisation der Bindestellen der beiden TSPs zu untersuchen.},

  abstract  = {Assumed comparable environmental conditions of early Mars and early Earth in 3.7 Ga ago - at a time when first fossil records of life on Earth could be found - suggest the possibility of life emerging on both planets in parallel. As conditions changed, the hypothetical life on Mars either became extinct or was able to adapt and might still exist in biological niches. The controversial discussed detection of methane on Mars led to the assumption, that it must have a recent origin - either abiotic through active volcanism or chemical processes, or through biogenic production. Spatial and seasonal variations in the detected methane concentrations and correlations between the presence of water vapor and geological features such as subsurface hydrogen, which are occurring together with locally increased detected concentrations of methane, gave fuel to the hypothesis of a possible biological source of the methane on Mars. Therefore the phylogenetically old methanogenic archaea, which have evolved under early Earth conditions, are often used as model-organisms in astrobiological studies to investigate the potential of life to exist in possible extraterrestrial habitats on our neighboring planet. In this thesis methanogenic archaea originating from two extreme environments on Earth were investigated to test their ability to be active under simulated Mars analog conditions. These extreme environments - the Siberian permafrost-affected soil and the chemoautotrophically based terrestrial ecosystem of Movile cave, Romania - are regarded as analogs for possible Martian (subsurface) habitats. Two novel species of methanogenic archaea isolated from these environments were described within the frame of this thesis. It could be shown that concentrations up to 1 wt\% of Mars regolith analogs added to the growth media had a positive influence on the methane production rates of the tested methanogenic archaea, whereas higher concentrations resulted in decreasing rates. Nevertheless it was possible for the organisms to metabolize when incubated on water-saturated soil matrixes made of Mars regolith analogs without any additional nutrients. Long-term desiccation resistance of more than 400 days was proven with reincubation and indirect counting of viable cells through a combined treatment with propidium monoazide (to inactivate DNA of destroyed cells) and quantitative PCR. Phyllosilicate rich regolith analogs seem to be the best soil mixtures for the tested methanogenic archaea to be active under Mars analog conditions. Furthermore, in a simulation chamber experiment the activity of the permafrost methanogen strain Methanosarcina soligelidi SMA-21 under Mars subsurface analog conditions could be proven. Through real-time wavelength modulation spectroscopy measurements the increase in the methane concentration at temperatures down to -5 °C could be detected. The results presented in this thesis contribute to the understanding of the activity potential of methanogenic archaea under Mars analog conditions and therefore provide insights to the possible habitability of present-day Mars (near) subsurface environments. Thus, it contributes also to the data interpretation of future life detection missions on that planet. For example the ExoMars mission of the European Space Agency (ESA) and Roscosmos which is planned to be launched in 2018 and is aiming to drill in the Martian subsurface.},

  abstract  = {Direct assessment of attitudes toward socially sensitive topics can be affected by deception attempts. Reaction-time based indirect measures, such as the Implicit Association Test (IAT), are less susceptible to such biases. Neuroscientific evidence shows that deception can evoke characteristic ERP differences. However, the cerebral processes involved in faking an IAT are still unknown. We randomly assigned 20 university students (15 females, 24.65 +/- 3.50 years of age) to a counterbalanced repeated-measurements design, requesting them to complete a Brief-IAT (BIAT) on attitudes toward doping without deception instruction, and with the instruction to fake positive and negative doping attitudes. Cerebral activity during BIAT completion was assessed using high-density EEG. Event-related potentials during faking revealed enhanced frontal and reduced occipital negativity, starting around 150 ms after stimulus presentation. Further, a decrease in the P300 and LPP components was observed. Source analyses showed enhanced activity in the right inferior frontal gyrus between 150 and 200 ms during faking, thought to reflect the suppression of automatic responses. Further, more activity was found for faking in the bilateral middle occipital gyri and the bilateral temporoparietal junction. Results indicate that faking reaction-time based tests alter brain processes from early stages of processing and reveal the cortical sources of the effects. Analyzing the EEG helps to uncover response patterns in indirect attitude tests and broadens our understanding of the neural processes involved in such faking. This knowledge might be useful for uncovering faking in socially sensitive contexts, where attitudes are likely to be concealed.},

  abstract  = {Die vorliegende Arbeit verfolgt das Ziel, aus geoinformatischer Sicht eine konzeptionelle Grundlage zur r{\"a}umlichen Optimierung von Immobilienportalen zu schaffen. Die Arbeit geht dabei von zwei Hypothesen aus: 1. Verfahren der r{\"a}umlichen Statistik und des Maschinellen Lernens zur Mietpreissch{\"a}tzung sind den bisher eingesetzten Verfahren der hedonischen Regression {\"u}berlegen und eignen sich zur r{\"a}umlichen Optimierung von Immobilienportalen. 2. Die von Immobilienportalen publizierten webbasierten Mietpreiskarten geben nicht die tats{\"a}chlichen r{\"a}umlichen Verh{\"a}ltnisse auf Immobilienm{\"a}rkten wieder. Alternative webbasierte Darstellungsformen, wie z.B. Gridmaps, sind dem Status Quo der Immobilienpreiskarten von Immobilienportalen {\"u}berlegen und visualisieren die tats{\"a}chlichen r{\"a}umlichen Verh{\"a}ltnisse von Immobilienpreisen zweckm{\"a}ßiger. Beide Thesen k{\"o}nnen bewiesen werden. Es erfolgt zun{\"a}chst eine umfangreiche Erhebung des Forschungsbedarfs mittels Literaturstudien und technologischer Recherche. Zur Beantwortung der Forschungsfragen wird als quantitative Datenbasis ein 74.098 Mietangebote umfassender Datensatz (von Januar 2007 bis September 2013) eines Immobilienportals akquiriert. Dieser reicht jedoch nicht in vollem Umfang zur Beantwortung der Fragestellungen aus. Deshalb f{\"u}hrt der Autor Experteninterviews zur Erhebung einer qualitativen Datenbasis. Deren Analyse ergibt in Kombination mit der Literaturstudie und der technologischen Recherche ein umfassendes, bisher so nicht verf{\"u}gbares Bild. Es stellt den Status Quo der r{\"a}umlichen Sicht sowie der raumanalytischen und geovisuellen Defizite von Immobilienportalen dar. Zur Optimierung der raumanalytischen und geovisuellen Defizite werden forschungsbasierte L{\"o}sungsans{\"a}tze herausgearbeitet und teilimplementiert. Methoden des Maschinellen Lernens und r{\"a}umliche Sch{\"a}tzverfahren werden als Alternativen zu den von Immobilienportalen bisher genutzten „nicht r{\"a}umlichen" Analyseverfahren zur Preismodellierung untersucht. Auf Grundlage eines hierf{\"u}r konzipierten Validierungsrahmens werden diese Methoden f{\"u}r die Nutzung im Kontext von Immobilienportalen adaptiert. Die prototypische Teilimplementierung zeigt die programmiertechnische Umsetzung des Konzeptes auf. Eine umfassende Analyse geeigneter Sekund{\"a}rvariablensets zur Mietpreissch{\"a}tzung liefert als methodisches Resultat, dass Interpolatoren, die Sekund{\"a}rvariablen ben{\"o}tigen (Kriging with external drift, Ordinary Cokriging), kaum zu valideren Mietpreissch{\"a}tzergebnissen gelangen als die Methode des Ordinary Kriging, die keine Sekund{\"a}rvariablen ben{\"o}tigt. Die Methoden Random Forest aus dem Maschinellen Lernen und die Geographisch Gewichtete Regression hingegen bergen großes Potential zur Nutzung der r{\"a}umlichen Mietpreissch{\"a}tzung im Kontext von Immobilien-portalen. Die Forschungsergebnisse der r{\"a}umlichen Preismodellierung werden in die r{\"a}umliche Visualisierung von Mietpreisen transferiert. F{\"u}r die webbasierte Mietpreisdarstellung wird ein Set alternativer Darstellungsmethoden entwickelt, um Mietpreiskarten-Prototypen abzuleiten. Ein methodisches Ergebnis der Entwicklung der Mietpreiskarten-Prototypen ist die Entwicklung eines geeigneten Ansatzes der Losl{\"o}sung des Preisbezugs von fachfremd verwendeten Bezugsgeometrien. Hierf{\"u}r wird vom Autor der Begriff der zonenlosen Preiskarte gepr{\"a}gt. Diese werden mit Methoden des Gridmapping erstellt. Es werden optimale Rasteraufl{\"o}sungen zur Darstellung interpolierter Rastergr{\"o}ßen ermittelt. Zonenlose Preiskarten mit Methoden des Gridmapping, gepaart mit einer optionalen geb{\"a}udescharfen Darstellung in gr{\"o}ßeren Maßst{\"a}ben, sind als Resultate der Forschung die bestm{\"o}gliche, sich an realen Verh{\"a}ltnissen orientierende, r{\"a}umliche Mietpreisdarstellung. Die entstandenen Prototypen sind eine Ann{\"a}herung der wahren Verteilung des Mietpreises im Raum und um einiges sch{\"a}rfer, als die auf der hedonischen Regression basierenden Darstellungen. Somit kann die wahre „Topographie" der Mietpreislandschaft abgebildet werden. Ein Einsatz der Karten f{\"u}r Nutzergruppen wie Makler, Investoren oder Kommunen zur Analyse st{\"a}dtischer Mietm{\"a}rkte ist denkbar. Alle entstandenen Prototypen sind unter der Nutzung von Map APIs umgesetzt. Ein Ergebnis dessen ist, dass Map APIs noch an diversen „Kinderkrankheiten" leiden und derart umgesetzte Mietpreiskarten noch einen weiten Weg vor sich haben, bis sie das Niveau thematischer Karten von Immhof oder Arnberger erreichen. Die konzeptionellen {\"U}berlegungen und Teilimplementierungen m{\"u}nden in drei Prozessketten, die Umsetzungsoptionen f{\"u}r eine r{\"a}umliche Optimierung von Immobilienportalen darstellen. Dabei werden zwei Szenarien f{\"u}r eine r{\"a}umlich optimierte Mietpreissch{\"a}tzung und ein Szenario f{\"u}r eine r{\"a}umlich optimierte Mietpreisdarstellung herausgearbeitet.},

Being indicators of cooperative goal interdependence in teams, both moderators are hypothesized to mitigate the positive association between the two conflict types. Findings from 88 development teams confirm the moderating effect for collective team identification, but not for team member alignment. Moreover, the moderating role of collective team identification is found to be dependent on the level of task conflict: It is more effective in decoupling task and relationship conflicts at medium as compared with high or low levels of task conflict.},

  abstract  = {The Norway lobster, Nephrops norvegicus, is a burrowing decapod with a rhythmic burrow emergence (24 h) governed by the circadian system. It is an important resource for European fisheries and its behavior deeply affects its availability. The current knowledge of Nephrops circadian biology is phenomenological as it is currently the case for almost all crustaceans. In attempt to elucidate the putative molecular mechanisms underlying circadian gene regulation in Nephrops, we used a transcriptomics approach on cDNA extracted from the eyestalk, a structure playing a crucial role in controlling behavior of decapods. We studied 14 male lobsters under 12-12 light-darkness blue light cycle. We used the Hiseq 2000 Illumina platform to sequence two eyestalk libraries (under light and darkness conditions) obtaining about 90 millions 100-bp paired-end reads. Trinity was used for the de novo reconstruction of transcriptomes; the size at which half of all assembled bases reside in contigs (N50) was equal to 1796 (light) and 2055 (darkness). We found a list of candidate clock genes and focused our attention on canonical ones: timeless, period, clock and bmal1. The cloning of assembled fragments validated Trinity outputs. The putative Nephrops clock genes showed high levels of identity (blastx on NCBI) with known crustacean clock gene homologs such as Eurydice pulchra (period: 47\%, timeless: 59\%, bmal1: 79\%) and Macrobrachium rosenbergii (clock: 100\%). We also found a vertebrate-like cryptochrome 2. RT-qPCR showed that only timeless had a robust diel pattern of expression. Our data are in accordance with the current knowledge of the crustacean circadian clock, reinforcing the idea that the molecular clockwork of this group shows some differences with the established model in Drosophila melanogaster.},

  abstract  = {The subject of the present thesis is the one-dimensional Bose gas. Since long-rang order is destroyed by infra-red fluctuations in one dimension, only the formation of a quasi-condensate is possible, which exhibits suppressed density fluctuations, but whose phase fluctuates strongly. It is shown that modified mean-field theories based on a symmetry-breaking approach can even characterise phase coherence properties of such a quasi-condensate properly. A correct description of the transition from the degenerate ideal Bose gas to the quasi-condensate, which is a smooth cross-over rather than a phase transition, is not possible though. Basic conditions for the applicability of the theories are not fulfilled in this regime, such that the existence of a critical point is predicted. The theories are compared on the basis of their excitation sprectum, equation of state, density fluctuations and related correlation functions. High-temperature expansions of the corresponding integrals are derived analytically for the numerical evaluation of the self-consistent integral equations. Apart from that, the Stochastic Gross-Pitaevskii equation (SGPE), a non-linear Langevin equation, is analysed numerically by means of Monte-Carlo simulations and the results are compared to those of the mean-field theories. In this context, a lot of attention is payed to the appropriate choice of the parameters. The simulations prove that the SGPE is capable of describing the cross-over properly, but highlight the limitations of the widely used local density approximation as well.},

  abstract  = {Der Zusammenhang zwischen Ern{\"a}hrung und der Entwicklung von chronischen Krankenheiten wie metabolischem Syndrom, Diabetes mellitus, Krebs und kardiovaskul{\"a}ren Erkrankungen wurde untersucht. Ver{\"a}nderungen der GH-IGF-1 Achse in Verbindung mit ern{\"a}hrungsbedingten Erkrankungen wurden fr{\"u}her beschrieben. Das Wechselspiel zwischen GH, gesamt IGF-1 und verschiedenen hemmenden und stimulierenden IGF-1 bindenden Proteinen (IGFBPs) bestimmt die IGF-1 Bioaktivit{\"a}t, die als die F{\"a}higkeit von IGF-1 die Phosphorylierung von seinem Rezeptor und folglich seinem Signalsweg zu induzieren, identifiziert ist. Deshalb reicht die Messung der IGF-1 Bioaktivit{\"a}t aus, um {\"A}nderungen des GH-IGF-1 Systems darzustellen. Studien deuten darauf hin, dass proteinreiche Di{\"a}t, gekennzeichnet durch erh{\"o}hte Glukagonsekretion, und Insulin-induzierte Hypoglyk{\"a}mie die Sterblichkeit erh{\"o}hen, und die Mechanismen sind unklar. Sowohl Glukagon als auch Insulin-induzierte Hypoglyk{\"a}mie stimulieren die GH Sekretion. Das Ziel der vorliegenden Studie war, die Wirkung von Glucagon und Insulin-induzierter Hypoglyk{\"a}mie auf die IGF-1 -Bioaktivit{\"a}t als m{\"o}gliche Mechanismen zu characterizieren. In einer doppelblinden, Placebo-kontrollierten Studie wurde Glukagon intramuskul{\"a}r 13 Patienten mit T1DM (6 M{\"a}nner / 7 Frauen; [ BMI ] : 24,8 ± 0,95 kg / m2) , 11 {\"u}bergewichtigen Teilnehmern (OP ; 5/6 ; 34,4 ± 1,7 kg / m2) und 13 gesunden schlanken Teilnehmern (LP ; 6/7 ; 21,7 ± 0,6 kg / m2) administriert. Zw{\"o}lf {\"u}bergewichtige Teilnehmer (OP ; 6/6 ; 34,4 ± 1,7 kg / m2) und 13 gesunde schlanke Teilnehmer (LP ; 6/7 ; 21,7 ± 0,6 kg / m2) f{\"u}hrten Insulintoleranztests in einer weiteren doppelblinden, Plazebo- kontrollierten Studie durch. {\"A}nderungen des GH, gesamt-IGF-1, der IGF-bindenden Proteinen ( IGFBPs ) und der IGF-1-Bioaktivit{\"a}t wurden durch das zellbasierte KIRA-Verfahren gemessen. Außerdem wurde die Wechselwirkung zwischen den metabolischen Hormonen (Glucagon und Insulin) und GH-IGF-1-System auf der Transkriptionsebene mit prim{\"a}ren Maus-Hepatozyten untersucht. In dieser Arbeit verringerte Glukagon die IGF-1-Bioaktivit{\"a}t bei den Menschen unabh{\"a}ngig von k{\"o}rpereigenen Insulinspiegeln, h{\"o}chstwahrscheinlich durch Modulation des IGFBP-1 und -2. Die Glukagon-induzierte Reduktion der IGF-1-Bioaktivit{\"a}t stellt einen neuen Mechanismus der Wirkung von Glucagon auf die GH-Sekretion dar und kann als m{\"o}gliche Erkl{\"a}rung f{\"u}r die negativen Auswirkungen der proteinreichen Di{\"a}t im Zusammenhang auf das erh{\"o}hte kardiovaskul{\"a}re Risiko und die Mortalit{\"a}t vorgeschlagen werden. Zus{\"a}tzlich wurde die Insulin-induzierten Hypoglyk{\"a}mie eine Abnahme der IGF-1-Bioaktivit{\"a}t durch Hochregulierung von IGFBP-2 zugeordnet. Diese Ergebnisse k{\"o}nnen auf m{\"o}gliche und wenig erforschte Mechanismen zur Erl{\"a}uterung der starken Assoziation zwischen Hypoglyk{\"a}mie und erh{\"o}hter kardiovaskul{\"a}rer Mortalit{\"a}t bei diabetischen Patienten beziehen.},

If the progenitors of Type Ib/c supernovae, which are believed to be Wolf-Rayet (WR) stars, have inflated envelopes then the shock breakout signals diffuse in them and can extend their rise times significantly. We show that our inflated, hydrogen-free, WR stellar models with a radius of ∼R⊙ can have shock breakout signals longer than ∼ 60 s. The puzzlingly long shock breakout signal observed in the Type Ib SN 2008D can be explained by an inflated progenitor envelope, and more such events might argue in favour of existence of inflated envelopes in general.},

  abstract  = {In the last decades, stellar atmosphere codes have become a key tool in understanding massive stars, including precise calculations of stellar and wind parameters, such as temperature, massloss rate, and terminal wind velocity. Nevertheless, for these models the hydrodynamic equation is not solved in the wind. Motivated by the results of the CAK theory, the models typically use a beta velocity law, which however turns out not to be adequate for stars with very strong winds, and treat the mass-loss rate as a free parameter. In a new branch of the Potsdam Wolf-Rayet model atmosphere (PoWR) code, we solve the hydrodynamic equation consistently throughout the stellar atmosphere. The PoWR code performs the calculation of the radiative force without approximations (e.g. Sobolev). We show the impact of hydrodynamically consistent modelling on OB and WR stars in comparison to conventional models and discuss the obtained velocity fields and their impact on the observed spectral lines.},

In wide WR+O binaries, such as WR 140, the X-ray flux is tied to the orbital phase, and is a direct probe of the winds' properties. In the Galactic center, ~30 WRs orbit the super massive black hole (SMBH) within ~10", leading to a smorgasbord of wind-wind collisions. To model the X-ray emission of WR 140 and the Galactic center, we perform 3D hydrodynamic simulations to trace the complex gaseous flows, and then carry out 3D radiative transfer calculations to compute the variable X-ray spectra. The model WR 140 RXTE light curve matches the data well for all phases except the X-ray minimum associated with periastron, while the model spectra agree with the RXTE hardness ratio and the shape of the Suzaku observations throughout the orbit. The Galactic center model of the Chandra flux and spectral shape match well in the region r ≤ 3", but the model flux falls off too rapidly beyond this radius.},

As such, the simultaneous presence of both late-type supergiants and Wolf-Rayet stars has defied explanation in the context of single-star evolution. Observational evidence points to a high binary fraction, hence this stellar population offers a robust test for stellar models accounting for both single-star and binary evolution. We present an optical to near-IR (VLT \& NTT) spectroscopic analysis of 22 WR stars in Wd 1, delivering physical properties for the WR stars. We discuss how these differ from the Galactic field population, and how they may be reconciled with the predictions of single and binary evolutionary models.},

  abstract  = {The overarching goal of this dissertation is to provide a better understanding of the role of wind and water in shaping Earth's Cenozoic orogenic plateaus - prominent high-elevation, low relief sectors in the interior of Cenozoic mountain belts. In particular, the feedbacks between surface uplift, the build-up of topography and ensuing changes in precipitation, erosion, and vegetation patterns are addressed in light of past and future climate change. Regionally, the study focuses on the two world's largest plateaus, the Altiplano-Puna Plateau of the Andes and Tibetan Plateau, both characterized by average elevations of >4 km. Both plateaus feature high, deeply incised flanks with pronounced gradients in rainfall, vegetation, hydrology, and surface processes. These characteristics are rooted in the role of plateaus to act as efficient orographic barriers to rainfall and to force changes in atmospheric flow. The thesis examines the complex topics of tectonic and climatic forcing of the surface-process regime on three different spatial and temporal scales: (1) bedrock wind-erosion rates are quantified in the arid Qaidam Basin of NW Tibet over millennial timescales using cosmogenic radionuclide dating; (2) present-day stable isotope composition in rainfall is examined across the south-central Andes in three transects between 22° S and 28° S; these data are modeled and assessed with remotely sensed rainfall data of the Tropical Rainfall Measuring Mission and the Moderate Resolution Imaging Spectroradiometer; (3) finally, a 2.5-km-long Mio-Pliocene sedimentary record of the intermontane Angastaco Basin (25°45' S, 66°00' W) is presented in the context of hydrogen and carbon compositions of molecular lipid biomarker, and oxygen and carbon isotopes obtained from pedogenic carbonates; these records are compared to other environmental proxies, including hydrated volcanic glass shards from volcanic ashes intercalated in the sedimentary strata. There are few quantitative estimates of eolian bedrock-removal rates from arid, low relief landscapes. Wind-erosion rates from the western Qaidam Basin based on cosmogenic 10Be measurements document erosion rates between 0.05 to 0.4 mm/yr. This finding indicates that in arid environments with strong winds, hyperaridity, exposure of friable strata, and ongoing rock deformation and uplift, wind erosion can outpace fluvial erosion. Large eroded sediment volumes within the Qaidam Basin and coeval dust deposition on the Chinese Loess plateau, exemplify the importance of dust production within arid plateau environments for marine and terrestrial depositional processes, but also health issues and fertilization of soils. In the south-central Andes, the analysis of 234 stream-water samples for oxygen and hydrogen reveals that areas experiencing deep convective storms do not show the commonly observed patterns of isotopic fractionation and the expected co-varying relationships between oxygen and hydrogen with increasing elevation. These convective storms are formed over semi-arid intermontane basins in the transition between the broken foreland of the Sierras Pampeanas, the Eastern Cordillera, and the Puna Plateau in the interior of the orogen. Here, convective rainfall dominates the precipitation budget and no systematic stable isotope-elevation relationship exists. Regions to the north, in the transition between the broken foreland and the Subandean foreland fold-and-thrust belt, the impact of convection is subdued, with lower degrees of storminess and a stronger expected isotope-elevation relationship. This finding of present-day fractionation trends of meteoric water is of great importance for paleoenvironmental studies in attempts to use stable isotope relationships in the reconstruction of paleoelevations. The third part of the thesis focuses on the paleohydrological characteristics of the Mio-Pliocene (10-2 Ma) Angastaco Basin sedimentary record, which reveals far-reaching environmental changes during Andean uplift and orographic barrier formation. A precipitation- evapotranspiration record identifies the onset of a precipitation regime related to the South American Low Level Jet at this latitude after 9 Ma. Humid foreland conditions existed until 7 Ma, followed by orographic barrier uplift to the east of the present-day Angastaco Basin. This was superseded by rapid (~0.5 Myr) aridification in an intermontane basin, highlighting the effects of eastward-directed deformation. A transition in vegetation cover from a humid C3 forest ecosystem to semi-arid C4-dominated vegetation was coeval with continued basin uplift to modern elevations.},

Construct validity of the measure was examined through correlations with parent- and self-reports of anger regulation and anger reactivity. Criterion validity was established through links with teacher-rated aggression and social rejection measured by parent-, teacher-, and self-reports. The observational measure correlated significantly with parent- and self-reports of anger reactivity, whereas it was unrelated to parent- and self-reports of anger regulation. It also made a unique contribution to predicting aggression and social rejection.},

  abstract  = {Background: Time-correlated Forster resonance energy transfer (FRET) probes molecular distances with greater accuracy than intensity-based calculation of FRET efficiency and provides a powerful tool to study biomolecular structure and dynamics. Moreover, time-correlated photon count measurements bear additional information on the variety of donor surroundings allowing more detailed differentiation between distinct structural geometries which are typically inaccessible to general fitting solutions. Results: Here we develop a new approach based on Monte Carlo simulations of time-correlated FRET events to estimate the time-correlated single photon counts (TCSPC) histograms in complex systems. This simulation solution assesses the full statistics of time-correlated photon counts and distance distributions of fluorescently labeled biomolecules. The simulations are consistent with the theoretical predictions of the dye behavior in FRET systems with defined dye distances and measurements of randomly distributed dye solutions. We validate the simulation results using a highly heterogeneous aggregation system and explore the conditions to use this tool in complex systems. Conclusion: This approach is powerful in distinguishing distance distributions in a wide variety of experimental setups, thus providing a versatile tool to accurately distinguish between different structural assemblies in highly complex systems.},

  abstract  = {Vegetated dunes are recognized as important natural barriers that shelter inland ecosystems and coastlines suffering daily erosive impacts of the sea and extreme events, such as tsunamis. However, societal responses to erosion and shoreline retreat often result in man-made coastal defence structures that cover part of the intertidal and upper shore zones causing coastal squeeze and habitat loss, especially for upper shore biota, such as dune plants. Coseismic uplift of up to 2.0 m on the Peninsula de Arauco (South central Chile, ca. 37.5 degrees S) caused by the 2010 Maule earthquake drastically modified the coastal landscape, including major increases in the width of uplifted beaches and the immediate conversion of mid to low sandy intertidal habitat to supralittoral sandy habitat above the reach of average tides and waves. To investigate the early stage responses in species richness, cover and across-shore distribution of the hitherto absent dune plants, we surveyed two formerly intertidal armoured sites and a nearby intertidal unarmoured site on a sandy beach located on the uplifted coast of Llico (Peninsula de Arauco) over two years. Almost 2 years after the 2010 earthquake, dune plants began to recruit, then rapidly grew and produced dune hummocks in the new upper beach habitats created by uplift at the three sites. Initial vegetation responses were very similar among sites. However, over the course of the study, the emerging vegetated dunes of the armoured sites suffered a slowdown in the development of the spatial distribution process, and remained impoverished in species richness and cover compared to the unarmoured site. Our results suggest that when released from the effects of coastal squeeze, vegetated dunes can recover without restoration actions. However, subsequent human activities and management of newly created beach and dune habitats can significantly alter the trajectory of vegetated dune development. Management that integrates the effects of natural and human induced disturbances, and promotes the development of dune vegetation as natural barriers can provide societal and conservation benefits in coastal ecosystems.},

  abstract  = {Fluid force microscopy combines the positional accuracy and force sensitivity of an atomic force microscope (AFM) with nanofluidics via a microchanneled cantilever. However, adequate loading and cleaning procedures for such AFM micropipettes are required for various application situations. Here, a new frontloading procedure is described for an AFM micropipette functioning as a force- and pressure-controlled microscale liquid dispenser. This frontloading procedure seems especially attractive when using target substances featuring high costs or low available amounts. Here, the AFM micropipette could be filled from the tip side with liquid from a previously applied droplet with a volume of only a few μL using a short low-pressure pulse. The liquid-loaded AFM micropipettes could be then applied for experiments in air or liquid environments. AFM micropipette frontloading was evaluated with the well-known organic fluorescent dye rhodamine 6G and the AlexaFluor647-labeled antibody goat anti-rat IgG as an example of a larger biological compound. After micropipette usage, specific cleaning procedures were tested. Furthermore, a storage method is described, at which the AFM micropipettes could be stored for a few hours up to several days without drying out or clogging of the microchannel. In summary, the rapid, versatile and cost-efficient frontloading and cleaning procedure for the repeated usage of a single AFM micropipette is beneficial for various application situations from specific surface modifications through to local manipulation of living cells, and provides a simplified and faster handling for already known experiments with fluid force microscopy.},

  abstract  = {Voltage-gated potassium (K+) channels are present in all living systems. Despite high structural similarities in the transmembrane domains (TMD), this K+ channel type segregates into at least two main functional categories-hyperpolarization-activated, inward-rectifying (Kin) and depolarization-activated, outward-rectifying (Kout) channels. Voltage-gated K+ channels sense the membrane voltage via a voltage-sensing domain that is connected to the conduction pathway of the channel. It has been shown that the voltage-sensing mechanism is the same in Kin and Kout channels, but its performance results in opposite pore conformations. It is not known how the different coupling of voltage-sensor and pore is implemented. Here, we studied sequence and structural data of voltage-gated K+ channels from animals and plants with emphasis on the property of opposite rectification. We identified structural hotspots that alone allow already the distinction between Kin and Kout channels. Among them is a loop between TMD S5 and the pore that is very short in animal Kout, longer in plant and animal Kin and the longest in plant Kout channels. In combination with further structural and phylogenetic analyses this finding suggests that outward-rectification evolved twice and independently in the animal and plant kingdom.},

Although temporal and spatial gradients in environmental variables are known to shape BCC, it remains unclear how and to what extent PA and FL bacterial diversity responds to such environmental changes. To elucidate the BCC of both bacterial fractions related to different environmental settings, we studied surface samples of three Baltic Sea stations (marine, mesohaline, and oligohaline) in two different seasons (summer and fall/winter). Amplicon sequencing of the 16S rRNA gene revealed significant differences in BCC of both bacterial fractions among stations and seasons, with a particularly high number of PA operational taxonomic units (OTUs at genus-level) at the marine station in both seasons. "Shannon and Simpson indices" showed a higher diversity of PA than FL bacteria at the marine station in both seasons and at the oligohaline station in fall/winter. In general, a high fraction of bacterial OTUs was found exclusively in the PA fraction (52\% of total OTUs). These findings indicate that PA bacteria significantly contribute to overall bacterial richness and that they differ from FL bacteria. Therefore, to gain a deeper understanding on diversity and dynamics of aquatic bacteria, PA and FL bacteria should be generally studied independently.},

  abstract  = {The dissertation proposes that the spread of photography and popular cinema in 19th- and 20th-century-India have shaped an aesthetic and affective code integral to the reading and interpretation of Indian English novels, particularly when they address photography and/or cinema film, as in the case of the four corpus texts. In analyzing the nexus between 'real' and 'reel', the dissertation shows how the texts address the reader as media consumer and virtual image projector. Furthermore, the study discusses the Indian English novel against the backdrop of the cultural and medial transformations of the 20th century to elaborate how these influenced the novel's aesthetics. Drawing upon reception aesthetics, the author devises the concept of the 'implied spectator' to analyze the aesthetic impact of the novels' images as visual textures. No God in Sight (2005) by Altaf Tyrewala comprises of a string of 41 interior monologues, loosely connected through their narrators' random encounters in Mumbai in the year 2000. Although marked by continuous perspective shifts, the text creates a sensation of acute immediacy. Here, the reader is addressed as implied spectator and is sutured into the narrated world like a film spectator ― an effect created through the use of continuity editing as a narrative technique. Similarly, Ruchir Joshi's The Last Jet Engine Laugh (2002) coll(oc)ates disparate narrative perspectives and explores photography as an artistic practice, historiographic recorder and epistemological tool. The narrative appears guided by the random viewing of old photographs by the protagonist and primary narrator, the photographer Paresh Bhatt. However, it is the photographic negative and the practice of superimposition that render this string of episodes and different perspectives narratively consequential and cosmologically meaningful. Photography thus marks the perfect symbiosis of autobiography and historiography. Tabish Khair's Filming. A Love Story (2007) immerses readers in the cine-aesthetic of 1930s and 40s Bombay film, the era in which the embedded plot is set. Plotline, central scenes and characters evoke the key films of Indian cinema history such as Satyajit Ray's "Pather Panchali" or Raj Kapoor's "Awara". Ultimately, the text written as film dissolves the boundary between fiction and (narrated) reality, reel and real, thereby showing that the images of individual memory are inextricably intertwined with and shaped by collective memory. Ultimately, the reconstruction of the past as and through film(s) conquers trauma and endows the Partition of India as a historic experience of brutal contingency with meaning. The Bioscope Man (Indrajit Hazra, 2008) is a picaresque narrative set in Calcutta - India's cultural capital and birthplace of Indian cinema at the beginning of the 20th century. The autodiegetic narrator Abani Chatterjee relates his rise and fall as silent film star, alternating between the modes of tell and show. He is both autodiegetic narrator and spectator or perceiving consciousness, seeing himself in his manifold screen roles. Beyond his film roles however, the narrator remains a void. The marked psychoanalytical symbolism of the text is accentuated by repeated invocations of dark caves and the laterna magica. Here too, 'reel life' mirrors and foreshadows real life as Indian and Bengali history again interlace with private history. Abani Chatterjee thus emerges as a quintessentially modern man of no qualities who assumes definitive shape only in the lost reels of the films he starred in. The final chapter argues that the static images and visual frames forwarded in the texts observe an integral psychological function: Premised upon linear perspective they imply a singular, static subjectivity appealing to the postmodern subject. In the corpus texts, the rise of digital technology in the 1990s thus appears not so much to have displaced older image repertories, practices and media techniques, than it has lent them greater visibility and appeal. Moreover, bricolage and pastiche emerge as cultural techniques which marked modernity from its inception. What the novels thus perpetuate is a media archeology not entirely servant to the poetics of the real. The permeable subject and the notion of the gaze as an active exchange as encapsulated in the concept of darshan - ideas informing all four texts - bespeak the resilience of a mythical universe continually re-instantiated in new technologies and uses. Eventually, the novels convey a sense of subalternity to a substantially Hindu nationalist history and historiography, the centrifugal force of which developed in the twentieth century and continues into the present.},

  abstract  = {Die Honigbiene Apis mellifera zeigt innerhalb einer Kolonie eine an das Alter gekoppelte Arbeitsteilung. Junge Honigbienen versorgen die Brut (Ammenbienen), w{\"a}hrend {\"a}ltere Honigbienen (Sammlerinnen) außerhalb des Stocks Pollen und Nektar eintragen. Die biogenen Amine Octopamin und Tyramin sind an der Steuerung der Arbeitsteilung maßgeblich beteiligt. Sie interagieren mit Zielzellen {\"u}ber die Bindung an G Protein gekoppelte Rezeptoren. A. mellifera besitzt f{\"u}nf charakterisierte Octopaminrezeptoren (AmOctαR1, AmOctβR1-4), einen charakterisierten Tyraminrezeptor (AmTyr1) sowie einen weiteren putativen Tyraminrezeptor. In der vorliegenden Arbeit wurde dieser putative Aminrezeptor als zweiter Tyraminrezeptor (AmTyr2) identifiziert, lokalisiert und pharmakologisch charakterisiert. Die von der cDNA abgeleitete Aminos{\"a}uresequenz weist strukturelle Eigenschaften und konservierte Motive von G Protein gekoppelten Rezeptoren auf. Phylogenetisch ordnet sich der AmTyr2 Rezeptor bei den Tyramin 2 Rezeptoren anderer Insekten ein. Die funktionelle und pharmakologische Charakterisierung des putativen Tyraminrezeptors erfolgte in modifizierten HEK293 Zellen, die mit der Rezeptor cDNA transfiziert wurden. Die Applikation von Tyramin aktiviert Adenylylcyclasen in diesen Zellen und resultiert in einem Anstieg des intrazellul{\"a}ren cAMP Gehalts. Der AmTyr2 Rezeptor kann durch Tyramin in nanomolaren Konzentrationen halbmaximal aktiviert werden. W{\"a}hrend es sich bei Octopamin um einen wirkungsvollen Agonisten des Rezeptors handelt, sind Mianserin und Yohimbin effektive Antagonisten. F{\"u}r die Lokalisierung des Rezeptorproteins wurde ein polyklonaler Antik{\"o}rper generiert. Eine AmTyr2-{\"a}hnliche Immunreaktivit{\"a}t zeigt sich im Gehirn in den optischen Loben, den Antennalloben, dem Zentralkomplex und in den Kenyon Zellen der Pilzk{\"o}rper. Des Weiteren wurde die Rolle der Octopamin- und Tyraminrezeptoren bei der Steuerung der altersabh{\"a}ngigen Arbeitsteilung analysiert. Die Genexpression des AmOctαR1 in verschiedenen Gehirnteilen korreliert unabh{\"a}ngig vom Alter mit der sozialen Rolle, w{\"a}hrend sich die Genexpression von AmOctβR3/4 und den Tyraminrezeptoren AmTyr1 und AmTyr2 maximal mit dem Alter aber nicht der sozialen Rolle {\"a}ndert. Sammlerinnen weisen einen h{\"o}heren Octopamingehalt im Gesamtgehirn auf als Ammenbienen; bei Tyramin zeigen sich keine Unterschiede. W{\"a}hrend Tyramin offensichtlich keine direkte Rolle spielt, werden durch Octopamin gesteuerte Prozesse der altersabh{\"a}ngigen Arbeitsteilung bei der Honigbiene vermutlich {\"u}ber den AmOctαR1 vermittelt. Die Ergebnisse der vorliegenden Arbeit zeigen die wichtige Rolle von biogenen Aminen, insbesondere Octopamin bei der sozialen Organisation von Insektenstaaten.},

  abstract  = {The transmission of wildlife zoonoses to humans depends, amongst others, on complex interactions of host population ecology and pathogen dynamics within host populations. In Europe, the Puumala virus (PUUV) causes nephropathia epidemica in humans. In this study we investigated complex interrelations within the epidemic system of PUUV and its rodent host, the bank vole (Myodes glareolus). We suggest that beech fructification and bank vole abundance are both decisive factors affecting human PUUV infections. While rodent host dynamics are expected to be directly linked to human PUUV infections, beech fructification is a rather indirect predictor by serving as food source for PUUV rodent hosts. Furthermore, we examined the dependence of bank vole abundance on beech fructification. We analysed a 12-year (2001-2012) time series of the parameters: beech fructification (as food resource for the PUUV host), bank vole abundance and human incidences from 7 Federal States of Germany. For the first time, we could show the direct interrelation between these three parameters involved in human PUUV epidemics and we were able to demonstrate on a large scale that human PUUV infections are highly correlated with bank vole abundance in the present year, as well as beech fructification in the previous year. By using beech fructification and bank vole abundance as predictors in one model we significantly improved the degree of explanation of human PUUV incidence. Federal State was included as random factor because human PUUV incidence varies considerably among states. Surprisingly, the effect of rodent abundance on human PUUV infections is less strong compared to the indirect effect of beech fructification. Our findings are useful to facilitate the development of predictive models for host population dynamics and the related PUUV infection risk for humans and can be used for plant protection and human health protection purposes.},

Als Ursache f{\"u}r regionale Unterschiede bei den Mortalit{\"a}tsraten werden divergente Versorgungsstrukturen vermutet. Ziel der Untersuchung war, diese Fragestellung anhand anonymisierter krankenkassenbasierter Abrechnungsdaten zu evaluieren. Methodik: Standardisierte Hospitalisierungs- sowie Krankenhaus- und Ein-Jahres-Mortalit{\"a}tsraten nach MI wurden anhand anonymisierter Versichertendaten einer gesetzlichen Krankenkasse f{\"u}r das Jahr 2012 und die Bundesl{\"a}nder Berlin, Brandenburg und Mecklenburg-Vorpommern ermittelt (n=1.387.084, 46.3\% male, 60.9 ± 18,2 years). Weiterhin wurden pr{\"a}diktive Einflussfaktoren auf die Ein-Jahres-Mortalit{\"a}t, auf die Durchf{\"u}hrung invasiver Prozeduren und auf eine leitliniengerechte pharmakotherapeutische Sekund{\"a}rpr{\"a}vention analysiert. Ergebnisse: 6.733 Patienten (73,7 ±13,0 Jahre, 56,7\% m{\"a}nnlich) wurden identifiziert. Obwohl f{\"u}r das Bundesland Berlin eine h{\"o}here Hospitalisierungsrate als in Mecklenburg-Vorpommern ermittelt werden konnte, ließen sich bei der Krankenhaus- und 1-Jahres-Mortalit{\"a}t keine signifikant abweichenden Raten zwischen den Bundesl{\"a}ndern beobachten. Die Durchf{\"u}hrung einer Koronarangiographie (OR: 0,42 [0,35-0,51]) und eine leitliniengerechte Pharmakotherapie (OR: 0,14 [0,12-0,17] waren mit einer geringeren 1-Jahres-Mortalit{\"a}t assoziiert. Die Durchf{\"u}hrung einer Koronarangiographie und eine leitliniengerechte Pharmakotherapie von Patienten nach Myokardinfarkt wurde hingegen prim{\"a}r durch Alter und Geschlecht, nicht aber durch das Bundesland determiniert. Folgerung: Eine regional divergierende station{\"a}re und postinfarzielle Versorgung auf Bundesland-Ebene kann anhand der vorliegenden Daten nicht nachgewiesen werden.},

  abstract  = {Gangsta-Rap ist besonders in Deutschland stark m{\"a}nnlich dominiert und als Musikgenre kommerziell sehr erfolgreich. Er gilt als eine der wenigen Zonen bislang weitestgehend unbedrohter M{\"a}nnlichkeitsentw{\"u}rfe. Die Ende des Jahres 2011 in Erscheinung getretene Gangsta-Rapperin ­Schwesta Ewa k{\"o}nnte gerade aufgrund ihres biologischen Geschlechts die Chance nutzen, M{\"a}nnlichkeitskonzeptionen und Vorstellungen von Weiblichkeit im Gangsta-­Rap infrage zu stellen. Doch welche Konstruktionen von M{\"a}nnlichkeit und Weiblichkeit stellen M{\"a}nner und Frauen in der Praxis genau auf? Zur Beantwortung dieser Forschungsfrage werden prim{\"a}r die soziologischen Konzepte zu hegemonialer M{\"a}nnlichkeit (Connell), Habitus (Bourdieu) und m{\"a}nnlichem Geschlechts­habitus (Meuser) herangezogen. Die theoriegeleitete, fallspezifische Zuordnung und Analyse von Songtexten erfolgt durch die empirische Methode der inhaltlich strukturierenden Inhaltsanalyse. Ein Ergebnis ist, dass Schwesta Ewa eine komplexe Eigen-Weiblichkeitskonstruktion aufstellt. {\"U}ber den Vergleich mit dem untersuchten Gangsta-Rapper Kollegah wird u. a. die These von Connell und Messerschmidt empirisch nachgewiesen, wonach auch Frauen Tr{\"a}ger von Aspekten hegemonialer M{\"a}nnlichkeit sein k{\"o}nnen. Die erste Forschungsfrage untersucht vor allem die homosoziale Dimension sowie das f{\"u}r Gangsta-Rap konstitutive Moment von Eigenaufwertung und Fremdabwertung. Welche Muster von Anerkennung existieren jedoch zwischen M{\"a}nnern und Frauen? F{\"u}r diese zweite Forschungsfrage wird eine Diskursanalyse durchgef{\"u}hrt, mit der viele K{\"u}nstler/-innen und ihre Songtexte untersucht werden. Es wird ermittelt, dass Gangsta-Rap auch als Repr{\"a}sentation konservativer Geschlechterbilder zu verstehen ist. Ebenso sind Schilderungen zu allt{\"a}glich erfahrbaren sozialen Ph{\"a}nomenen wie Liebe und Freundschaft als auch zu den damit einhergehenden sozialen Rollen vorzufinden. Die Perspektive gegengeschlechtlicher Wertsch{\"a}tzung kann aber gleichzeitig ablaufende Abwertung beibehalten.},

  abstract  = {Plant cell walls are complex structures that underpin plant growth and are widely exploited in diverse human activities thus placing them with a central importance in biology. Cell walls have been a prominent area of research for a long time, but the chemical complexity and diversity of cell walls not just between species, but also within plants, between cell-types, and between cell wall micro-domains pose several challenges. Progress accelerated several-fold in cell wall biology owing to advances in sequencing technology, aided soon thereafter by advances in omics and imaging technologies. This development provides additional perspectives of cell walls across a rapidly growing number of species, highlighting a myriad of architectures, compositions, and functions. Furthermore, rather than the component centric view, integrative analysis of the different cell wall components across system-levels help to gain a more in-depth understanding of the structure and biosynthesis of the cell envelope and its interactions with the environment. To this end, in this work three case studies are detailed, all pertaining to the integrative analysis of heterogeneous cell wall related data arising from different system-levels and analytical techniques. A detailed account of multiblock methods is provided and in particular canonical correlation and regression methods of data integration are discussed. In the first integrative analysis, by employing canonical correlation analysis - a multivariate statistical technique to study the association between two datasets - novel insight to the relationship between glycans and phenotypic traits is gained. In addition, sparse partial least squares regression approach that adapts Lasso penalization and allows for the selection of a subset of variables was employed. The second case study focuses on an integrative analysis of images obtained from different spectroscopic techniques. By employing yet another multiblock approach - multiple co-inertia analysis, insitu biochemical composition of cell walls from different cell-types is studied thereby highlighting the common and complementary parts of the two hyperspectral imaging techniques. Finally, the third integrative analysis facilitates gene expression analysis of the Arabidopsis root transcriptome and translatome for the identification of cell wall related genes and compare expression patterns of cell wall synthesis genes. The computational analysis considered correlation and variation of expression across cell-types at both system-levels, and also provides insight into the degree of co-regulatory relationships that are preserved between the two processes. The integrative analysis of glycan data and phenotypic traits in cotton fibers using canonical methods led to the identification of specific polysaccharides which may play a major role during fiber development for the final fiber characteristics. Furthermore, this analysis provides a base for future studies on glycan arrays in case of developing cotton fibers. The integrative analysis of images from infrared and Raman spectroscopic approaches allowed the coupling of different analytical techniques to characterize complex biological material, thereby, representing various facets of their chemical properties. Moreover, the results from the co-inertia analysis demonstrated that the study was well adapted as it is relevant for coupling data tables in a symmetric way. Several indicators are proposed to investigate how the global and block scores are related. In addition, studying the root cells of \textit{Arabidopsis thaliana} allowed positing a novel pipeline to systematically investigate and integrate the different levels of information available at the global and single-cell level. The conducted analysis also confirms that previously identified key transcriptional activators of secondary cell wall development display highly conserved patterns of transcription and translation across the investigated cell-types. Moreover, the biological processes that display conserved and divergent patterns based on the cell-type-specific expression and translation levels are identified.},

  abstract  = {Welfare states and policies have changed greatly over the past decades, mostly characterized by retrenchments in terms of government spending or in terms of restricted access to certain benefits. In the area of family policies, however, a lot of countries have simultaneously expanded provisions and transfers for families. Bringing together the macro analysis of policy variation and household income changes on the micro-level, the main research question of the dissertation is to what extent economic consequences following separation and divorce in families with children have changed between the 1980s and the 2000s in Germany and the United States. The second research question of the dissertation regards the differences in dissolution outcomes between married and cohabiting parents in Germany. The dissertation thus aims to link institutional regulations of welfare states with the actual income situation of families. To achieve this, a research design was developed that has never been used for the analysis of the economic consequences of family dissolution. For this, the two longest running panel datasets, German Socio-economic Panel (GSOEP) and the US American Panel Study of Income Dynamics (PSID), have been used. The analytic strategy applied to estimate the effects of family dissolution on household income is a difference-in-difference design combined with coarsened exact matching (CEM). To begin with, the dissertation confirmed many findings of previous research, for example regarding the gender differences in family dissolution outcomes. Mothers experience clearly higher relative income losses and consequently higher risks of poverty than fathers. This finding is universal, that is it holds for both countries, for all time periods observed, and for all measures of economic outcome that were employed. Another confirmed finding is the higher level of welfare state intervention in Germany compared to the United States. The dissertation also revealed a number of novel findings. The results show that the expansion of family policies in Germany over time has not been accompanied by substantially decreasing income losses for mothers. Though income losses have slightly decreased over time, they have become more persistent during the years following family dissolution. The impact of the German welfare state has meanwhile been quite stable. American mothers' income losses took place on a slightly lower level than those of German mothers. Only during the 1980s their relative losses were clearly lower than those of German mothers. And also American mothers did not recover as much from their income losses during the 2000s than they used to during the 1980s. For them, the 1996 welfare reform brought a considerable decrease in welfare state support. Accordingly, the results for American mothers can certainly be described as a shift from public to private provision. The general finding of previous studies that fathers do not have to suffer income losses, or if at all rather moderate ones compared to mothers, can be confirmed. Nevertheless, both German and US American fathers face a deterioration of the economic consequences of family dissolution over time. German fathers' relative income changes are still positive though they have decreased over time. One reason for this decrease is the increasing loss of partner earnings following union dissolution. Also among American fathers, income gains still prevail in the year of family dissolution. Two years later, however, they have been facing income losses already since the 1980s which have furthermore increased considerably over time. Zooming in on Germany, family dissolution outcomes by marital status show negligible differences between cohabiting and married mothers in disposable income, but considerable differences in losses of income before taxes and transfers. It is the impact of the welfare state that equalizes the differences in income losses between these two groups of mothers. For married mothers, losses are not as high in the year of event but they have difficulties to recover from these losses. Without the income buffering of the welfare state, married mothers would, three years after family dissolution, remain with relative income losses double as high as for cohabiting mothers. Compared to mothers, differences between married and cohabiting fathers are visible in changes of income before as well as after taxes and transfers. The welfare state does not alter the difference between the two groups of fathers. With regard to both income concepts, cohabiting fathers fare worse than married fathers. Cohabiting fathers suffer moderate income losses of disposable income while married fathers experience moderate income gains. Accounting for support payments is decisive for fathers' income changes. If these payments are not deducted from disposable income, both married and cohabiting fathers experience gains in disposable income following family dissolution.},

Since mixed effects modeling had enabled researchers to investigate more complex problems with more precision than before, two naming experiments were conducted with college students, with and without non-words intermixed, and analyzed with regard to frequency, quality, interactive and trial-history effects. The present analyses build on and extend the Bates, Kliegl, Vasishth, and Baayen (2015) approach in order to converge on a parsimonious model that accounts for autocorrelated errors caused by trial history. For three of four cases, a history-sensitive model improved the model fit over a history-na{\"i}ve model and explained more deviance. In one of these cases, the herein presented approach helped reveal an interaction between stimulus frequency and quality that was not significant without a trial history account. Main and joint effects, limitations, as well as directions for further research, are briefly discussed.},

Thus, transcriptional gene-regulation is often controlled by poorly expressed transcription-factors, such as E.coli lac repressor with few tens of copies. Here we study the effects of inherent concentration fluctuations of substrate-molecules on the seminal Michaelis-Menten scheme of biochemical reactions. We present a universal correction to the Michaelis-Menten equation for the reaction-rates. The relevance and validity of this correction for enzymatic reactions and intracellular gene-regulation is demonstrated. Our analytical theory and simulation results confirm that the proposed variance-corrected Michaelis-Menten equation predicts the rate of reactions with remarkable accuracy even in the presence of large non-equilibrium concentration fluctuations. The major advantage of our approach is that it involves only the mean and variance of the substrate-molecule concentration. Our theory is therefore accessible to experiments and not specific to the exact source of the concentration fluctuations.},

  abstract  = {The high-latitudinal thermospheric processes driven by the solar wind and Interplanetary Magnetic Field (IMF) interaction with the Earth magnetosphere are highly variable parts of the complex dynamic plasma environment, which represent the coupled Magnetosphere - Ionosphere - Thermosphere (MIT) system. The solar wind and IMF interactions transfer energy to the MIT system via reconnection processes at the magnetopause. The Field Aligned Currents (FACs) constitute the energetic links between the magnetosphere and the Earth ionosphere. The MIT system depends on the highly variable solar wind conditions, in particular on changes of the strength and orientation of the IMF. In my thesis, I perform an investigation on the physical background of the complex MIT system using the global physical - numerical, three-dimensional, time-dependent and self-consistent Upper Atmosphere Model (UAM). This model describes the thermosphere, ionosphere, plasmasphere and inner magnetosphere as well as the electrodynamics of the coupled MIT system for the altitudinal range from 80 (60) km up to the 15 Earth radii. In the present study, I developed and investigated several variants of the high-latitudinal electrodynamic coupling by including the IMF dependence of FACs into the UAM model. For testing, the various variants were applied to simulations of the coupled MIT system for different seasons, geomagnetic activities, various solar wind and IMF conditions. Additionally, these variants of the theoretical model with the IMF dependence were compared with global empirical models. The modelling results for the most important thermospheric parameters like neutral wind and mass density were compared with satellite measurements. The variants of the UAM model with IMF dependence show a good agreement with the satellite observations. In comparison with the empirical models, the improved variants of the UAM model reproduce a more realistic meso-scale structures and dynamics of the coupled MIT system than the empirical models, in particular at high latitudes. The new configurations of the UAM model with IMF dependence contribute to the improvement of space weather prediction.},

  abstract  = {During the last two decades, instability training devices have become a popular means in athletic training and rehabilitation of mimicking unstable surfaces during movements like vertical jumps. Of note, under unstable conditions, trunk muscles seem to have a stabilizing function during exercise to facilitate the transfer of torques and angular momentum between the lower and upper extremities. The present thesis addresses the acute effects of surface instability on performance during jump-landing tasks. Additionally, the long-term effects (i.e., training) of surface instability were examined with a focus on the role of the trunk in athletic performance/physical fitness. Healthy adolescent, and young adult subjects participated in three cross-sectional and one longitudinal study, respectively. Performance in jump-landing tasks on stable and unstable surfaces was assessed by means of a ground reaction force plate. Trunk muscle strength (TMS) was determined using an isokinetic device or the Bourban TMS test. Physical fitness was quantified by standing long jump, sprint, stand-and-reach, jumping sideways, Emery balance, and Y balance test on stable surfaces. In addition, activity of selected trunk and leg muscles and lower limb kinematics were recorded during jump-landing tasks. When performing jump-landing tasks on unstable compared to stable surfaces, jump performance and leg muscle activity were significantly lower. Moreover, significantly smaller knee flexion angles and higher knee valgus angles were observed when jumping and landing on unstable compared to stable conditions and in women compared to men. Significant but small associations were found between behavioral and neuromuscular data, irrespective of surface condition. Core strength training on stable as well as on unstable surfaces significantly improved TMS, balance and coordination. The findings of the present thesis imply that stable rather than unstable surfaces provide sufficient training stimuli during jump exercises (i.e., plyometrics). Additionally, knee motion strategy during plyometrics appears to be modified by surface instability and sex. Of note, irrespective of surface condition, trunk muscles only play a minor role for leg muscle performance/activity during jump exercises. Moreover, when implemented in strength training programs (i.e., core strength training), there is no advantage in using instability training devices compared to stable surfaces in terms of enhancement of athletic performance.},

  abstract  = {Gashydrate sind kristalline Feststoffe bestehend aus Wasser und Gasmolek{\"u}len. Sie sind stabil bei erh{\"o}hten Dr{\"u}cken und niedrigen Temperaturen. Nat{\"u}rliche Hydratvorkommen treten daher an Kontinentalh{\"a}ngen, in Permafrostb{\"o}den und in tiefen Seen sowie Binnenmeeren auf. Bei der Hydratbildung orientieren sich die Wassermolek{\"u}le neu und bilden sogenannte K{\"a}figstrukturen, in die Gas eingelagert werden kann. Aufgrund des hohen Drucks bei der Hydratbildung k{\"o}nnen große Mengen an Gas in die Hydratstruktur eingebaut werden. Das Volumenverh{\"a}ltnis von Wasser zu Gas kann dabei bis zu 1:172 bei 0°C und Atmosph{\"a}rendruck betragen. Nat{\"u}rliche Gashydrate enthalten haupts{\"a}chlich Methan. Da Methan sowohl ein Treibhausgas als auch ein Brenngas ist, stellen Gashydrate gleichermaßen eine potentielle Energieressource sowie eine m{\"o}gliche Quelle f{\"u}r Treibhausgase dar. Diese Arbeit untersucht die physikalischen Eigenschaften von Methanhydrat ges{\"a}ttigten Sedimentproben im Labormaßstab. Dazu wurde ein großer Reservoirsimulator (LARS) mit einer eigens entwickelten elektrischen Widerstandstomographie ausger{\"u}stet, die das erste Mal an hydratges{\"a}ttigten Sedimentproben unter kontrollierten Temperatur-, Druck-, und Hydrats{\"a}ttigungsbedingungen im Labormaßstab angewendet wurde. {\"U}blicherweise ist der Porenraum von (marinen) Sedimenten mit elektrisch gut leitendem Salzwasser gef{\"u}llt. Da Hydrate einen elektrischen Isolator darstellen, ergeben sich große Kontraste hinsichtlich der elektrischen Eigenschaften im Porenraum w{\"a}hrend der Hydratbildung und -zersetzung. Durch wiederholte Messungen w{\"a}hrend der Hydraterzeugung ist es m{\"o}glich die r{\"a}umliche Widerstandsverteilung in LARS aufzuzeichnen. Diese Daten bilden in der Folge die Grundlage f{\"u}r eine neue Auswerteroutine, welche die r{\"a}umliche Widerstandsverteilung in die r{\"a}umliche Verteilung der Hydrats{\"a}ttigung {\"u}berf{\"u}hrt. Dadurch ist es m{\"o}glich, die sich {\"a}ndernde Hydrats{\"a}ttigung sowohl r{\"a}umlich als auch zeitlich hoch aufgel{\"o}st w{\"a}hrend der gesamten Hydraterzeugungsphase zu verfolgen. Diese Arbeit zeigt, dass die entwickelte Widerstandstomographie eine gute Datenqualit{\"a}t aufwies und selbst geringe Hydrats{\"a}ttigungen innerhalb der Sedimentprobe detektiert werden konnten. Bei der Umrechnung der Widerstandsverteilung in lokale Hydrat-S{\"a}ttigungswerte wurden die besten Ergebnisse mit dem Archie-var-phi Ansatz erzielt, der die zunehmende Hydratphase dem Sedimentger{\"u}st zuschreibt, was einer Abnahme der Porosit{\"a}t gleichkommt. Die Widerstandsmessungen zeigten weiterhin, dass die schnelle Hydraterzeugung im Labor zur Ausbildung von kleinen Hydratkristallen f{\"u}hrte, die dazu neigten, zu rekristalliesieren. Es wurden weiterhin Hydrat-Abbauversuche durchgef{\"u}hrt, bei denen die Hydratphase {\"u}ber Druckerniedrigung in Anlehnung an den 2007/2008 Mallik Feldtest zersetzt wurde. Dabei konnte beobachtet werden, dass die Muster der Gas- undWasserflussraten im Labor zum Teil gut nachgebildet werden konnten, jedoch auch aufbaubedingte Abweichungen auftraten. In zwei weiteren Langzeitversuchen wurde die Realisierbarkeit und das Verhalten bei CO2-CH4-Hydrat Austauschversuchen in LARS untersucht. Das tomographische Messsystem wurde dabei genutzt um w{\"a}hrend der CH4 Hydrat Aufbauphase die Hydratverteilung innerhalb der Sedimentprobe zu {\"u}berwachen.

Three units in the first pilot covered aspects of using digital technologies to develop creative thinking skills. The findings in this paper relate to the fourth unit about e-mentoring, a skill that was important to delivering the course content in the other three units. Findings about the e-mentoring unit included: the students' request for detailed profiles so that participants can get to know each other; and, the need to reconcile the different interpretations of e-mentoring held by the participants when the course begins. The evaluators concluded that the major issues were that: not all professional learners would self-organise and network; and few would wish to mentor their colleagues voluntarily. Therefore, the e-mentoring issues will need careful consideration in pilots two and three to identify how e-mentoring will be organised.},

  abstract  = {Winter storms are the most costly natural hazard for European residential property. We compare four distinct storm damage functions with respect to their forecast accuracy and variability, with particular regard to the most severe winter storms. The analysis focuses on daily loss estimates under differing spatial aggregation, ranging from district to country level. We discuss the broad and heavily skewed distribution of insured losses posing difficulties for both the calibration and the evaluation of damage functions. From theoretical considerations, we provide a synthesis between the frequently discussed cubic wind-damage relationship and recent studies that report much steeper damage functions for European winter storms. The performance of the storm loss models is evaluated for two sources of wind gust data, direct observations by the German Weather Service and ERA-Interim reanalysis data. While the choice of gust data has little impact on the evaluation of German storm loss, spatially resolved coefficients of variation reveal dependence between model and data choice. The comparison shows that the probabilistic models by Heneka et al. (2006) and Prahl et al. (2012) both provide accurate loss predictions for moderate to extreme losses, with generally small coefficients of variation. We favour the latter model in terms of model applicability. Application of the versatile deterministic model by Klawa and Ulbrich (2003) should be restricted to extreme loss, for which it shows the least bias and errors comparable to the probabilistic model by Prahl et al. (2012).},

  abstract  = {Global food production needs to be increased by 60-110\% between 2005 and 2050 to meet growing food and feed demand. Intensification and/or expansion of agriculture are the two main options available to meet the growing crop demands. Land conversion to expand cultivated land increases GHG emissions and impacts biodiversity and ecosystem services. Closing yield gaps to attain potential yields may be a viable option to increase the global crop production. Traditional methods of agricultural intensification often have negative externalities. Therefore, there is a need to explore location-specific methods of sustainable agricultural intensification. We identified regions where the achievement of potential crop calorie production on currently cultivated land will meet the present and future food demand based on scenario analyses considering population growth and changes in dietary habits. By closing yield gaps in the current irrigated and rain-fed cultivated land, about 24\% and 80\% more crop calories can respectively be produced compared to 2000. Most countries will reach food self-sufficiency or improve their current food self-sufficiency levels if potential crop production levels are achieved. As a novel approach, we defined specific input and agricultural management strategies required to achieve the potential production by overcoming biophysical and socioeconomic constraints causing yield gaps. The management strategies include: fertilizers, pesticides, advanced soil management, land improvement, management strategies coping with weather induced yield variability, and improving market accessibility. Finally, we estimated the required fertilizers (N, P2O5, and K2O) to attain the potential yields. Globally, N-fertilizer application needs to increase by 45-73\%, P2O5-fertilizer by 22-46\%, and K2O-fertilizer by 2-3 times compared to the year 2010 to attain potential crop production. The sustainability of such agricultural intensification largely depends on the way management strategies for closing yield gaps are chosen and implemented.},

  abstract  = {Anthropogenic activities have transformed the Earth's environment, not only on local level, but on the planetary-scale causing global change. Besides industrialization, agriculture is a major driver of global change. This change in turn impairs the agriculture sector, reducing crop yields namely due to soil degradation, water scarcity, and climate change. However, this is a more complex issue than it appears. Crop yields can be increased by use of agrochemicals and fertilizers which are mainly produced by fossil energy. This is important to meet the increasing food demand driven by global demographic change, which is further accelerated by changes in regional lifestyles. In this dissertation, we attempt to address this complex problem exploring agricultural potential globally but on a local scale. For this, we considered the influence of lifestyle changes (dietary patterns) as well as technological progress and their effects on climate change, mainly greenhouse gas (GHG) emissions. Furthermore, we examined options for optimizing crop yields in the current cultivated land with the current cropping patterns by closing yield gaps. Using this, we investigated in a five-minute resolution the extent to which food demand can be met locally, and/or by regional and/or global trade. Globally, food consumption habits are shifting towards calorie rich diets. Due to dietary shifts combined with population growth, the global food demand is expected to increase by 60-110\% between 2005 and 2050. Hence, one of the challenges to global sustainability is to meet the growing food demand, while at the same time, reducing agricultural inputs and environmental consequences. In order to address the above problem, we used several freely available datasets and applied multiple interconnected analytical approaches that include artificial neural network, scenario analysis, data aggregation and harmonization, downscaling algorithm, and cross-scale analysis. Globally, we identified sixteen dietary patterns between 1961 and 2007 with food intakes ranging from 1,870 to 3,400 kcal/cap/day. These dietary patterns also reflected changing dietary habits to meat rich diets worldwide. Due to the large share of animal products, very high calorie diets that are common in the developed world, exhibit high total per capita emissions of 3.7-6.1 kg CO2eq./day. This is higher than total per capita emissions of 1.4-4.5 kg CO2eq./day associated with low and moderate calorie diets that are common in developing countries. Currently, 40\% of the global crop calories are fed to livestock and the feed calorie use is four times the produced animal calories. However, these values vary from less than 1 kcal to greater 10 kcal around the world. On the local and national scale, we found that the local and national food production could meet demand of 1.9 and 4.4 billion people in 2000, respectively. However, 1 billion people from Asia and Africa require intercontinental agricultural trade to meet their food demand. Nevertheless, these regions can become food self-sufficient by closing yield gaps that require location specific inputs and agricultural management strategies. Such strategies include: fertilizers, pesticides, soil and land improvement, management targeted on mitigating climate induced yield variability, and improving market accessibility. However, closing yield gaps in particular requires global N-fertilizer application to increase by 45-73\%, P2O5 by 22-46\%, and K2O by 2-3 times compare to 2010. Considering population growth, we found that the global agricultural GHG emissions will approach 7 Gt CO2eq./yr by 2050, while the global livestock feed demand will remain similar to 2000. This changes tremendously when diet shifts are also taken into account, resulting in GHG emissions of 20 Gt CO2eq./yr and an increase of 1.3 times in the crop-based feed demand between 2000 and 2050. However, when population growth, diet shifts, and technological progress by 2050 were considered, GHG emissions can be reduced to 14 Gt CO2eq./yr and the feed demand to nearly 1.8 times compare to that in 2000. Additionally, our findings shows that based on the progress made in closing yield gaps, the number of people depending on international trade can vary between 1.5 and 6 billion by 2050. In medium term, this requires additional fossil energy. Furthermore, climate change, affecting crop yields, will increase the need for international agricultural trade by 4\% to 16\%. In summary, three general conclusions are drawn from this dissertation. First, changing dietary patterns will significantly increase crop demand, agricultural GHG emissions, and international food trade in the future when compared to population growth only. Second, such increments can be reduced by technology transfer and technological progress that will enhance crop yields, decrease agricultural emission intensities, and increase livestock feed conversion efficiencies. Moreover, international trade dependency can be lowered by consuming local and regional food products, by producing diverse types of food, and by closing yield gaps. Third, location specific inputs and management options are required to close yield gaps. Sustainability of such inputs and management largely depends on which options are chosen and how they are implemented. However, while every cultivated land may not need to attain its potential yields to enable food security, closing yield gaps only may not be enough to achieve food self-sufficiency in some regions. Hence, a combination of sustainable implementations of agricultural intensification, expansion, and trade as well as shifting dietary habits towards a lower share of animal products is required to feed the growing population.},

  abstract  = {The drainage and cultivation of fen peatlands create complex small-scale mosaics of soils with extremely variable soil organic carbon (SOC) stocks and groundwater levels (GWLs). To date, the significance of such sites as sources or sinks for greenhouse gases such as CO2 and CH4 is still unclear, especially if the sites are used for cropland. As individual control factors such as GWL fail to account for this complexity, holistic approaches combining gas fluxes with the underlying processes are required to understand the carbon (C) gas exchange of drained fens. It can be assumed that the stocks of SOC and N located above the variable GWL - defined as dynamic C and N stocks - play a key role in the regulation of the plant- and microbially mediated CO2 fluxes in these soils and, inversely, for CH4. To test this assumption, the present study analysed the C gas exchange (gross primary production - GPP; ecosystem respiration - R-eco; net ecosystem exchange - NEE; CH4) of maize using manual chambers for 4 years. The study sites were located near Paulinenaue, Germany, where we selected three soil types representing the full gradient of GWL and SOC stocks (0-1 m) of the landscape: (a) Haplic Arenosol (AR; 8 kg C m(-2)); (b) Mollic Gleysol (GL; 38 kg C m(-2)); and (c) Hemic Histosol (HS; 87 kg C m(-2)). Daily GWL data were used to calculate dynamic SOC (SOCdyn) and N (N-dyn) stocks. Average annual NEE differed considerably among sites, ranging from 47 +/- 30 g C m(-2) yr(-1) in AR to -305 +/- 123 g C m(-2) yr(-1) in GL and -127 +/- 212 g C m(-2) yr(-1) in HS. While static SOC and N stocks showed no significant effect on C fluxes, SOCdyn and N-dyn and their interaction with GWL strongly influenced the C gas exchange, particularly NEE and the GPP : R-eco ratio. Moreover, based on nonlinear regression analysis, 86\% of NEE variability was explained by GWL and SOCdyn. The observed high relevance of dynamic SOC and N stocks in the aerobic zone for plant and soil gas exchange likely originates from the effects of GWL-dependent N availability on C formation and transformation processes in the plant-soil system, which promote CO2 input via GPP more than CO2 emission via R-eco. The process-oriented approach of dynamic C and N stocks is a promising, potentially generalisable method for system-oriented investigations of the C gas exchange of groundwater-influenced soils and could be expanded to other nutrients and soil characteristics. However, in order to assess the climate impact of arable sites on drained peatlands, it is always necessary to consider the entire range of groundwater-influenced mineral and organic soils and their respective areal extent within the soil landscape.},

  abstract  = {The invention and development of next or second generation sequencing methods has resulted in a dramatic transformation of ancient DNA research and allowed shotgun sequencing of entire genomes from fossil specimens. However, although there are exceptions, most fossil specimens contain only low (similar to 1\% or less) percentages of endogenous DNA. The only skeletal element for which a systematically higher endogenous DNA content compared to other skeletal elements has been shown is the petrous part of the temporal bone. In this study we investigate whether (a) different parts of the petrous bone of archaeological human specimens give different percentages of endogenous DNA yields, (b) there are significant differences in average DNA read lengths, damage patterns and total DNA concentration, and (c) it is possible to obtain endogenous ancient DNA from petrous bones from hot environments. We carried out intra-petrous comparisons for ten petrous bones from specimens from Holocene archaeological contexts across Eurasia dated between 10,0001,800 calibrated years before present (cal. BP). We obtained shotgun DNA sequences from three distinct areas within the petrous: a spongy part of trabecular bone (part A), the dense part of cortical bone encircling the osseous inner ear, or otic capsule (part B), and the dense part within the otic capsule (part C). Our results confirm that dense bone parts of the petrous bone can provide high endogenous aDNA yields and indicate that endogenous DNA fractions for part C can exceed those obtained for part B by up to 65-fold and those from part A by up to 177-fold, while total endogenous DNA concentrations are up to 126-fold and 109-fold higher for these comparisons. Our results also show that while endogenous yields from part C were lower than 1\% for samples from hot (both arid and humid) parts, the DNA damage patterns indicate that at least some of the reads originate from ancient DNA molecules, potentially enabling ancient DNA analyses of samples from hot regions that are otherwise not amenable to ancient DNA analyses.},

  abstract  = {Zwei h{\"a}ufig diskutierte Aspekte der sp{\"a}tk{\"a}nozoischen Gebirgsbildung der Anden sind der Zeitpunkt sowie die Art und Weise der Heraushebung des Puna-Plateaus und seiner Randgebiete innerhalb der Ostkordillere und die damit verbundenen klimatischen {\"A}nderungen in NW Argentinien. Die Ostkordillere trennt die Bereiche des endorheischen, ariden Plateaus von semiariden und extern entw{\"a}sserten intermontanen Becken sowie dem humiden Andenvorland im Osten. Diese Unterschiede verdeutlichen die Bedeutung der {\"o}stlichen Flanken der Anden als orografische Barrieren gegen{\"u}ber feuchten Luftmassen aus dem Osten und spiegelt sich auch in ausgepr{\"a}gten Relief- und Topografiegradienten, der Niederschlagsverteilung, und der Effizienz von Oberfl{\"a}chenprozessen wider. Obwohl das {\"u}bergeordnete Deformationsmuster in diesem Teil der Anden eine ostw{\"a}rts gerichtete Wanderung der Deformationsprozesse im Gebirge indiziert, gibt es hier keine klar definierte Deformationsfront. Hebungsvorg{\"a}nge und die damit im Zusammenhang stehenden Sedimentprozesse setzen r{\"a}umlich und zeitlich sehr unterschiedlich ein. Zudem gestalten periodisch wiederkehrende Deformationsereignisse innerhalb intermontaner Becken und diachrone Hebungsvorg{\"a}nge, durch Reaktivierung {\"a}lterer Sockelstrukturen im Vorland, eine detaillierte Auswertung der r{\"a}umlich-zeitlichen Hebungsmuster zus{\"a}tzlich schwierig. Die vorliegende Arbeit konzentriert sich haupts{\"a}chlich auf die tektonische Entwicklung der Ostkordillere im Nordwesten Argentiniens, die Ablagerungsgeschichte ihrer intermontanen Sedimentbecken und die topografische Entwicklung der Ostflanke des andinen Puna-Plateaus. Im Allgemeinen sind sich die Sedimentbecken der Ostkordillere und der angrenzenden Provinzen, den Sierras Pampeanas und der Santa B{\´a}rbara Region, den durch St{\"o}rungen begrenzten und mit Sedimenten verf{\"u}llten Becken der hochandinen Plateauregion sehr {\"a}hnlich. Deutliche Unterschiede zur Puna bestehen aber dennoch, denn wiederholte Deformations-, Erosions- und Sedimentationsprozesse haben in den intermontanen Becken zu einer vielf{\"a}ltigen Stratigrafie, {\"U}berlagerungsprozessen und einer durch tektonische Prozesse und klimatischen Wandel charakterisierten Landschaft beigetragen. Je nach Erhaltungsgrad k{\"o}nnen in einigen F{\"a}llen Spuren dieser sediment{\"a}ren und tektonischen Entwicklung bis in die Zeit zur{\"u}ckreichen, als diese Bereiche des Gebirges noch Teil eines zusammenh{\"a}ngenden und unverformten Vorlandbeckens waren. Im Nordwesten Argentiniens enthalten k{\"a}nozoische Sedimente zahlreiche datierbare und geochemisch korrelierbare Vulkanaschen, die nicht nur als wichtige Leithorizonte zur Entschl{\"u}sselung tektonischer und sediment{\"a}rer Ereignisse dienen. Die vulkanischen Gl{\"a}ser dieser Aschen archivieren außerdem Wasserstoff-Isotopenverh{\"a}ltnisse fr{\"u}herer Oberfl{\"a}chenwasser, mit deren Hilfe - im Vergleich mit den Isotopenverh{\"a}ltnissen rezenter meteorischer W{\"a}sser - die r{\"a}umliche und zeitliche Entstehung orografischer Barrieren und tektonisch erzwungene Klima- und Umweltver{\"a}nderungen verfolgt werden k{\"o}nnen. Uran-Blei-Datierungen an Zirkonen aus den vulkanischen Aschelagen und die Rekonstruktion sediment{\"a}rer Pal{\"a}otransportrichtungen im intermontanen Humahuaca-Becken in der Ostkordillere (23.5° S) deuten an, dass das heutige Becken bis vor etwa 4.2 Ma Bestandteil eines gr{\"o}ßtenteils uneingeschr{\"a}nkten Ablagerungsbereichs war, der sich bis ins Vorland erstreckt haben muss. Deformation und Hebung {\"o}stlich des heutigen Beckens sorgten dabei f{\"u}r eine fortschreitende Entkopplung des Entw{\"a}sserungsnetzes vom Vorland und eine Umlenkung der Flussl{\"a}ufe nach S{\"u}den. In der Folge erzwang die weitere Hebung der Gebirgsbl{\"o}cke das Abregnen {\"o}stlicher Luftmassen in immer {\"o}stlicher gelegene Bereiche. Zudem k{\"o}nnen periodische Schwankungen der hydrologischen Verbindung des Beckens mit dem Vorland im Zusammenhang mit der Ablagerung und Erosion m{\"a}chtiger Beckenf{\"u}llungen identifiziert werden. Systematische Beziehungen zwischen Verwerfungen, regionalen Diskontinuit{\"a}ten und verstellten Terrassenfl{\"a}chen verweisen außerdem auf ein generelles Muster beckeninterner Deformation, vermutlich als Folge umfangreicher Beckenerosion und damit verbundenen {\"A}nderungen im tektonischen Spannungsfeld der Region. Einige dieser Beobachtungen k{\"o}nnen anhand ver{\"a}nderter Wasserstoff-Isotopenkonzentrationen vulkanischer Gl{\"a}ser aus der k{\"a}nozoischen Stratigrafie untermauert werden. Die δDg-Werte zeigen zwei wesentliche Trends, die einerseits in Verbindung mit Oberfl{\"a}chenhebung innerhalb des Einzugsgebiets zwischen 6.0 und 3.5 Ma stehen und andererseits mit dem Einsetzen semiarider Bedingungen durch Erreichen eines Schwellenwertes der Topografie der {\"o}stlich gelegenen Gebirgsz{\"u}ge nach 3.5 Ma erkl{\"a}rt werden k{\"o}nnen. Tektonisch bedingte Unterbrechung der Sedimentzufuhr aus westlich gelegenen Liefergebieten um 4.2 Ma und die folgende Hinterland-Aridifizierung deuten weiterhin auf die M{\"o}glichkeit hin, dass diese Prozesse die Folge eines lateralen Wachstums des Puna-Plateaus sind. Diese Aridifizierung im Bereich der Puna resultierte in einem ineffizienten, endorheischen Entw{\"a}sserungssystem, das dazu beigetragen hat, das Plateau vor Einschneidung und externer Entw{\"a}sserung zu bewahren und Reliefgegens{\"a}tze aufgrund fortgesetzter Beckensedimentation reduzierte. Die diachrone Natur der Hebungen und Beckenbildungen sowie deren Auswirkungen auf das Flusssystem im angrenzenden Vorland wird sowohl durch detaillierte Analysen der Sedimentherkunft und Transportrichtungen als auch Uran-Blei-Datierungen im Lerma- und Met{\´a}n-Becken (25° S) weiterhin unterstrichen. Das wird besonders deutlich am Beispiel der isolierten Hebung der Sierra de Met{\´a}n vor etwa 10 Ma, die mehr als 50 km von der aktiven orogenen Front im Westen entfernt liegt. Ab 5 Ma sind typische Lithologien der Puna nicht mehr in den Vorlandsedimenten nachweisbar, welches die weitere Hebung innerhalb der Ostkordillere und die hydrologische Isolation des Angastaco-Beckens in dieser Region dokumentiert. Im Sp{\"a}tplioz{\"a}n und Quart{\"a}r ist die Deformation letztlich {\"u}ber das gesamte Vorland verteilt und bis heute aktiv. Um die Beziehungen zwischen tektonisch kontrollierten Ver{\"a}nderungen der Topografie und deren Einfluss auf atmosph{\"a}rische Prozesse besser zu verstehen, werden in dieser Arbeit weitere altersspezifische Wasserstoff-Isotopendaten vulkanischer Gl{\"a}ser aus dem zerbrochenen Vorland, dem Angastaco-Becken in der {\"U}bergangsregion zwischen Ostkordillere und Punarand und anderer intermontaner Becken weiter s{\"u}dlich vorgestellt. Die Resultate dokumentieren {\"a}hnliche H{\"o}henlagen der untersuchten Regionen bis ca. 7 Ma, gefolgt von Hebungsprozessen im Bereich des Angastaco-Beckens. Ein Vergleich mit Isotopendaten vom benachbarten Puna-Plateau hilft abrupte δDg-Schwankungen in den intermontanen Daten zu erkl{\"a}ren und untermauert die Existenz wiederkehrender Phasen verst{\"a}rkt konvektiver Wetterlagen im Plioz{\"a}n, {\"a}hnlich heutigen Bedingungen. In dieser Arbeit werden gel{\"a}ndeorientierte und geochemische Methoden kombiniert, um Erkenntnisse {\"u}ber die Abl{\"a}ufe von topografiebildenden Deformations- und Hebungsprozessen zu gewinnen und Wechselwirkungen mit der daraus resultierenden Niederschlagsverteilung, Erosion und Sedimentation innerhalb tektonisch aktiver Gebirge zu erforschen. Diese Erkenntnisse sind f{\"u}r ein besseres Verst{\"a}ndnis von Subduktionsgebirgen essentiell, besonders hinsichtlich des Deformationsstils und der zeitlich-r{\"a}umlichen Beziehungen bei der Hebung und Sedimentbeckenbildung. Diese Arbeit weist dar{\"u}berhinaus auf die Bedeutung stabiler Isotopensysteme zur Beantwortung pal{\"a}oaltimetrischer Fragestellungen und zur Erforschung von Pal{\"a}oumweltbedingungen hin und liefert wichtige Erkenntnisse f{\"u}r einen kritischen Umgang mit solchen Daten in anderen Regionen.},

  abstract  = {It has been observed for many African languages that focussed subjects have to appear outside of their syntactic base position, as opposed to focussed objects, which can remain in-situ. This is known as subjectobject asymmetry of focus marking, which Fiedler et al. (2010) claim to hold also for Akan. Genzel (2013), on the other hand, argues that Akan does not exhibit a subject-object focus asymmetry. A questionnaire study and a production experiment were carried out to investigate whether focussed subjects may indeed be realized in-situ in Akan. The results suggest that (i) focussed subjects do not have to be obligatorily realized ex-situ, and that (ii) the syntactic preference for the realization of a focussed subject highly depends on exhaustivity.},

  abstract  = {During the course of their ontogenesis plants are continuously exposed to a large variety of abiotic stress factors which can damage tissues and jeopardize the survival of the organism unless properly countered. While animals can simply escape and thus evade stressors, plants as sessile organisms have developed complex strategies to withstand them. When the intensity of a detrimental factor is high, one of the defense programs employed by plants is the induction of programmed cell death (PCD). This is an active, genetically controlled process which is initiated to isolate and remove damaged tissues thereby ensuring the survival of the organism. The mechanism of PCD induction usually includes an increase in the levels of reactive oxygen species (ROS) which are utilized as mediators of the stress signal. Abiotic stress-induced PCD is not only a process of fundamental biological importance, but also of considerable interest to agricultural practice as it has the potential to significantly influence crop yield. Therefore, numerous scientific enterprises have focused on elucidating the mechanisms leading to and controlling PCD in response to adverse conditions in plants. This knowledge may help develop novel strategies to obtain more resilient crop varieties with improved tolerance and enhanced productivity. The aim of the present review is to summarize the recent advances in research on ROS-induced PCD related to abiotic stress and the role of the organelles in the process.},

  abstract  = {The polymorphism of immunogenes of the major histocompatibility complex (MHC) is thought to influence the functional plasticity of immune responses and, consequently, the fitness of populations facing heterogeneous pathogenic pressures. Here, we evaluated MHC variation (allelic richness and divergence) and patterns of selection acting on the two highly polymorphic MHC class II loci (DRB and DQB) in the endangered primate Madame Berthe's mouse lemur (Microcebus berthae). Using 454 pyrosequencing, we examined MHC variation in a total of 100 individuals sampled over 9 years in Kirindy Forest, Western Madagascar, and compared our findings with data obtained previously for its sympatric congener, the grey mouse lemur (Microcebus murinus). These species exhibit a contrasting ecology and demography that were expected to affect MHC variation and molecular signatures of selection. We found a lower allelic richness concordant with its low population density, but a similar level of allelic divergence and signals of historical selection in the rare feeding specialist M. berthae compared to the widespread generalist M. murinus. These findings suggest that demographic factors may exert a stronger influence than pathogen-driven selection on current levels of allelic richness in M. berthae. Despite a high sequence similarity between the two congeners, contrasting selection patterns detected at DQB suggest its potential functional divergence. This study represents a first step toward unravelling factors influencing the adaptive divergence of MHC genes between closely related but ecologically differentiated sympatric lemurs and opens new questions regarding potential functional discrepancy that would explain contrasting selection patterns detected at DQB.},

  abstract  = {Im Rahmen der EU-weiten REACH-Verordnung haben Alternativmethoden zum Tierversuch in der Toxikologie an Bedeutung gewonnen. Die Alternativmethoden gliedern sich auf in In-vitro- und In-silico-Methoden. In dieser Dissertation wurden verschiedene Konzepte der In-silico-Toxikologie behandelt. Die bearbeiteten Themen reichen von quantitativen Strukturaktivit{\"a}tsbeziehungen (QSAR) {\"u}ber eine neue Herangehensweise an das g{\"a}ngige Konzept zur Festlegung von Grenzwerten bis hin zu computerbasierten Modellierungen zum Alkohol- und Bisphenol-A-Stoffwechsel. Das Kapitel {\"u}ber QSAR befasst sich im Wesentlichen mit der Erstellung und Analyse einer Datenbank mit 878 Substanzen, die sich aus Tierversuchsstudien aus dem Archiv des Bundesinstituts f{\"u}r Risikobewertung zusammensetzt. Das Design wurde dabei an eine bereits bestehende Datenbank angepasst, um so einen m{\"o}glichst großen Datenpool zu generieren. In der Analyse konnte u.a. gezeigt werden, dass Stoffe mit niedrigerem Molekulargewicht ein erh{\"o}htes Potential f{\"u}r toxikologische Sch{\"a}den aufwiesen als gr{\"o}ßere Molek{\"u}le. Mit Hilfe des sogenannten TTC-Konzepts k{\"o}nnen Grenzwerte f{\"u}r Stoffe geringer Exposition festgelegt werden, zu denen keine toxikologischen Daten zur Verf{\"u}gung stehen. In dieser Arbeit wurden f{\"u}r die Stoffe dreier Datenbanken entsprechende Grenzwerte festgelegt. Es erfolgte zun{\"a}chst eine g{\"a}ngige strukturbasierte Aufteilung der Substanzen in die Kategorien "nicht toxisch", "m{\"o}glicherweise toxisch" und "eindeutig toxisch". Substanzen, die aufgrund ihrer Struktur in eine der drei Klassen eingeordnet werden, erhalten den entsprechenden Grenzwert. Da in die dritte Klasse auch Stoffe eingeordnet werden, deren Toxizit{\"a}t nicht bestimmbar ist, ist sie sehr groß. Daher wurden in dieser Arbeit die ersten beiden Klassen zusammengelgt, um einen gr{\"o}ßeren Datenpool zu erm{\"o}glichen. Eine weitere Neuerung umfasst die Erstellung eines internen Grenzwerts. Diese Vorgehensweise hat den Vorteil, dass der Expositionsweg herausgerechnet wird und somit beispielsweise Studien mit oraler Verabreichung mit Studien dermaler Verabreichung verglichen werden k{\"o}nnen. Mittels physiologisch basiertem kinetischem Modelling ist es m{\"o}glich, Vorg{\"a}nge im menschlichen K{\"o}rper mit Hilfe spezieller Software nachzuvollziehen. Durch diese Vorgehensweise k{\"o}nnen Expositionen von Chemikalien simuliert werden. In einem Teil der Arbeit wurden Alkoholexpositionen von gestillten Neugeborenen simuliert, deren M{\"u}tter unmittelbar zuvor alkoholische Getr{\"a}nke konsumiert hatten. Mit dem Modell konnte gezeigt werden, dass die Expositionen des Kindes durchweg gering waren. Nach einem Glas Wein wurden Spitzenkonzentrationen im Blut von Neugeborenen von 0,0034 Promille ermittelt. Zum Vergleich wurde die Exposition durch ein f{\"u}r S{\"a}uglinge zugelassenes alkoholhaltiges pflanzliches Arzneimittel simuliert. Hier wurden Spitzenkonzentrationen von 0,0141 Promille erreicht. Daher scheinen Empfehlungen wie gelegentlicher Konsum ohne sch{\"a}digende Wirkung auf das Kind wissenschaftlich fundiert zu sein. Ein weiteres Kinetik-Modell befasste sich mit dem Stoffwechsel von Bisphenol A. Teils widerspr{\"u}chliche Daten zur Belastung mit BPA in der wissenschaftlichen Literatur f{\"u}hren wiederholt zu Anregungen, den Grenzwert der Chemikalie anzupassen. Die Funktionalit{\"a}t der am Metabolismus beteiligten Enzyme kann je nach Individuum unterschiedlich ausgepr{\"a}gt sein. Mittels Modellings konnte hier gezeigt werden, dass dies maßgeblich dazu f{\"u}hrt, dass sich berechnete Plasmaspiegel von Individuen bis zu 4,7-fach unterscheiden. Die Arbeit konnte somit einen Beitrag zur Nutzung und Weiterentwicklung von In-silico-Modellen f{\"u}r diverse toxikologische Fragestellungen leisten.},

The obtained velocity is in qualitative agreement with Super Dual Auroral Radar Network data. Our method can supplement currently available instruments for ionospheric plasma velocity measurements, especially in cases where these traditional instruments suffer from their inherent limitations. Also, the method can be generalized to other satellite constellations carrying electron density probes.},

  abstract  = {Peak oil is forcing our society to shift from fossil to renewable resources. However, such renewable resources are also scarce, and they too must be used in the most efficient and sustainable way possible. Biorefining is a concept that represents both resource efficiency and sustainability. This approach initiates a cascade use, which means food and feed production before material use, and an energy-related use at the end of the value-added chain. However, sustainability should already start in the fields, on the agricultural side, where the industrially-used biomass is produced. Therefore, the aim of my doctoral thesis is to analyse the sustainable feedstock supply for biorefineries. In contrast to most studies on biorefineries, I focus on the sustainable provision of feedstock and not on the bioengineering processing of whatever feedstock is available. Grasslands provide a high biomass potential. They are often inefficiently used, so a new utilisation concept based on the biorefining approach can increase the added value from grasslands. Fodder legumes from temporary and permanent grasslands were chosen for this study. Previous research shows that they are a promising feedstock for industrial uses, and their positive environmental impact is an important byproduct to promote sustainable agricultural production systems. Green Biorefineries are a class of biorefineries that use fresh green biomass, such as grasses or fodder legumes, as feedstock. After fractionation, an organic solution (press juice) forms; this is used for the production of organic acids, chemicals and extracts, as well as fertilisers. A fibre component (press cake) is also created to produce feed, biomaterials and biogas. This thesis examines a specific value chain, using alfalfa and clover/grass as feedstock and generating lactic acid and one type of cattle feed from it. The research question is if biomass production needs to be adapted for the utilisation of fodder legumes in the Green Biorefinery approach. I have attempted to give a holistic analysis of cultivation, processing and utilisation of two specific grassland crops. Field trials with alfalfa and clover/grass at different study sites were carried out to obtain information on biomass quality and quantity depending on the crop, study site and harvest time. The fresh biomass was fractionated with a screw press and the composition of press juices and cakes was analysed. Fermentation experiments took place to determine the usability of press juices for lactic acid production. The harvest time is not of high importance for the quality of press juices as a fermentation medium. For permanent grasslands, late cuts, often needed for reasons of nature conservation, are possible without a major influence on feedstock quality. The press cakes were silaged for feed-value determination. Following evidence that both intermediate products are suitable feedstocks in the Green Biorefinery approach, I developed a cost-benefit analysis, comparing different production scenarios on a farm. Two standard crop rotations for Brandenburg, producing either only market crops or market crops and fodder legumes for ruminant feed production, were compared to a system that uses the cultivated fodder legumes for the Green Biorefinery value chain instead of only feed production. Timely processing of the raw material is important to maintain quality for industrial uses, so on-site processing at the farm is assumed in Green Biorefinery scenario. As a result, more added value stays in the rural area. Two farm sizes, common for many European regions, were chosen to examine the influence of scale. The cost site of farmers has also been analysed in detail to assess which farm characteristics make production of press juices for biochemical industries viable. Results show that for large farm sizes in particular, the potential profits are high. Additionally, the wider spectrum of marketable products generates new sources of income for farmers. The holistic analysis of the supply chain provides evidence that the cultivation processes for fodder legumes do not need to be adapted for use in Green Biorefineries. In fact, the new utilisation approach even widens the cultivation and processing spectrum and can increase economic viability of fodder legume production in conventional farming.},

  abstract  = {We report the results from two experiments investigating how referential context information affects native and non-native readers' interpretation of ambiguous relative clauses in sentences such as The journalist interviewed the assistant of the inspector who was looking very serious. The preceding discourse context was manipulated such that it provided two potential referents for either the first (the assistant) or the second (the inspector) of the two noun phrases that could potentially host the relative clause, thus biasing towards either an NP1 or an NP2 modification reading. The results from an offline comprehension task indicate that both native English speakers' and German and Chinese-speaking ESL learners' ultimate interpretation preferences were reliably influenced by the type of referential context. In contrast, in a corresponding self-paced-reading task we found that referential context information modulated only the non-native participants' disambiguation preferences but not the native speakers'. Our results corroborate and extend previous findings suggesting that non-native comprehenders' initial analysis of structurally ambiguous input is strongly influenced by biasing discourse information.},
