T1 - Asymmetric term alignment with selective contiguity constraints by multi-tape automata
N2 - This article describes a HMM-based word-alignment method that can selectively enforce a contiguity constraint. This method has a direct application in the extraction of a bilingual terminological lexicon from a parallel corpus, but can also be used as a preliminary step for the extraction of phrase pairs in a Phrase-Based Statistical Machine Translation system. Contiguous source words composing terms are aligned to contiguous target language words. The HMM is transformed into a Weighted Finite State Transducer (WFST) and contiguity constraints are enforced by specific multi-tape WFSTs. The proposed method is especially suited when basic linguistic resources (morphological analyzer, part-of-speech taggers and term extractors) are available for the source language only.

N2 - A degree course in IT and business administration solely for women (FIW) has been offered since 2009 at the HTW Berlin – University of Applied Sciences. This contribution discusses student motivations for enrolling in such a women only degree course and gives details of our experience over recent years. In particular, the approach to attracting new female students is described and the composition of the intake is discussed. It is shown that the women-only setting together with other factors can attract a new clientele for computer science.

T1 - Binding and degradation of juvenile hormone III by haemolymph proteins of the Colorado potato beetle: a re-examination
N2 - The haemolymph of the adult Colorado potato beetle, Lepinotarsa decemlineata Say, contains a high molecular weight (MW > 200,000) JH-III specific binding protein. The Kd value of the protein for racemic JH-III is 1.3 ± 0.2 × 10−7 M. It has a lower affinity for racemic JH-I and it does not bind JH-III-diol or JH-III-acid. The binding protein does discriminate between the enantiomers of synthetic, racemic JH-III as was determined by stereochemical anaysis of the bound and the free JH-III. Incubation of racemic JH-III with crude haemolymph results in preferential formation of (10S)-JH-III-acid, the unnatural configuration. The JH-esterase present in L. decemlineata haemolymph is not enantioselective. It is concluded that the most important function of the binding protein is that of a specific carrier, protecting the natural hormone against degradation by esterases. The carrier does not protect JH-I as efficiently as the lower homologue.

I contend that employing the concepts of conviviality, ethnic/religious/national indifference, and similarity will greatly facilitate answering these questions.

T1 - Bridging boundaries: creating linkages : non-central governments and multilayered policy environments
N2 - Observers of international politics have been conscious of the growing international involvement of non-central governments (NCGs), particularly in federal systems. These have been supplemented by the internationalisation of subnational actors in quasi-federal and even unitary states. One of the difficulties is that analysis has often been locked into the dominant paradigm debate in International Relations concerning who and who are not significant actors. Having briefly explored the nature of this changing environment, marked by a growing emphasis on access rather than control as a policy objective and the emergence of what is termed a 'catalytic diplomacy', the discussion focuses on the need for linkage between the levels of government in the pursuit of international as well as domestic policy goals. The nature of linkage mechanisms are discussed.

T1 - Capillary electrophoresis as a fast and universal tool in soil analysis
N2 - Fast analysis of different species of molecules in soils is investigated by capillary electrophoresis (CE). Several CE techniques for the analysis of inorganic ions and carbohydrates have been tested. With regard to the intents of pedologists and the usually large number of soil analyses a bundle of CE systems is proposed, capable of effecting time-saving soil analyses. Adapted electrolyte systems recently published and new separation systems are described. Examples of the application of these methods to two different soil samples are presented.

T1 - Causes for slow weathering and erosion in the steep, warm, monsoon-subjected Highlands of Sri Lanka
T1 - Ursache von langsamer Verwitterung und Erosion im steilen, warmen und Monsun-beeinflussten Hochland von Sri Lanka
N2 - In the Highlands of Sri Lanka, erosion and chemical weathering rates are among the lowest for global mountain denudation. In this tropical humid setting, highly weathered deep saprolite profiles have developed from high-grade metamorphic charnockite during spheroidal weathering of the bedrock. The spheroidal weathering produces rounded corestones and spalled rindlets at the rock-saprolite interface. I used detailed textural, mineralogical, chemical, and electron-microscopic (SEM, FIB, TEM) analyses to identify the factors limiting the rate of weathering front advance in the profile, the sequence of weathering reactions, and the underlying mechanisms. The first mineral attacked by weathering was found to be pyroxene initiated by in situ Fe oxidation, followed by in situ biotite oxidation. Bulk dissolution of the primary minerals is best described with a dissolution – re-precipitation process, as no chemical gradients towards the mineral surface and sharp structural boundaries are observed at the nm scale. Only the local oxidation in pyroxene and biotite is better described with an ion by ion process. The first secondary phases are oxides and amorphous precipitates from which secondary minerals (mainly smectite and kaolinite) form. Only for biotite direct solid state transformation to kaolinite is likely. The initial oxidation of pyroxene and biotite takes place in locally restricted areas and is relatively fast: log J = -11 molmin/(m2 s). However, calculated corestone-scale mineral oxidation rates are comparable to corestone-scale mineral dissolution rates: log R = -13 molpx/(m2 s) and log R = -15 molbt/(m2 s). The oxidation reaction results in a volume increase. Volumetric calculations suggest that this observed oxidation leads to the generation of porosity due to the formation of micro-fractures in the minerals and the bedrock allowing for fluid transport and subsequent dissolution of plagioclase. At the scale of the corestone, this fracture reaction is responsible for the larger fractures that lead to spheroidal weathering and to the formation of rindlets. Since these fractures have their origin from the initial oxidational induced volume increase, oxidation is the rate limiting parameter for weathering to take place. The ensuing plagioclase weathering leads to formation of high secondary porosity in the corestone over a distance of only a few cm and eventually to the final disaggregation of bedrock to saprolite. As oxidation is the first weathering reaction, the supply of O2 is a rate-limiting factor for chemical weathering. Hence, the supply of O2 and its consumption at depth connects processes at the weathering front with erosion at the surface in a feedback mechanism. The strength of the feedback depends on the relative weight of advective versus diffusive transport of O2 through the weathering profile. The feedback will be stronger with dominating diffusive transport. The low weathering rate ultimately depends on the transport of O2 through the whole regolith, and on lithological factors such as low bedrock porosity and the amount of Fe-bearing primary minerals. In this regard the low-porosity charnockite with its low content of Fe(II) bearing minerals impedes fast weathering reactions. Fresh weatherable surfaces are a pre-requisite for chemical weathering. However, in the case of the charnockite found in the Sri Lankan Highlands, the only process that generates these surfaces is the fracturing induced by oxidation. Tectonic quiescence in this region and low pre-anthropogenic erosion rate (attributed to a dense vegetation cover) minimize the rejuvenation of the thick and cohesive regolith column, and lowers weathering through the feedback with erosion.
N2 - Erosions- und chemische Verwitterungsraten im srilankischen Hochland gehören zu den langsamsten der globalen Gebirgsdenudationsraten. In diesem tropischen, humiden Gebiet entwickelten sich mächtige Verwitterungsprofile – sogenannte Saprolite – auf spheroidal verwittertem, hochgradig metamorphen Charnockit. Spheroidale Verwitterung führt zu abgerundeten „corestones“ mit abgesplitterten Rinden („rindlets“) an der Gesteins – Saprolit Grenze. Zur Identifizierung der ratenlimitierenden Faktoren des Fortschreiten der Verwitterungsfront, der Sequenz der Verwitterungsreaktionen und der dahinterliegenden Mechanismen nutzte ich detaillierte gesteinsstrukturelle, mineralogische, chemische und elektronenmikroskopische (SEM, FIB, TEM) Analysemethoden. Die initiale Verwitterung beginnt mit lokal begrenzter in situ Oxidation in Pyroxen, gefolgt von in situ Oxidation von Biotit. Die Auflösung der Minerale wird am besten durch einen Auflöse – Wiederausfällungs-prozess beschrieben, da zur Mineralgrenze hin keine chemischen Gradienten, dafür aber auf der nm-Skala scharfe strukturelle Grenzen zu beobachten sind. Die ersten ausfallenden Sekundärphasen sind Oxide und amorphe Phasen aus denen sich Sekundärmineral (hauptsächlich Smectit und Kaolinit) bilden. Für Biotit ist auch eine direkte Umwandlung im Festzustand zu Kaolinit möglich. Die initiale Pyroxen- und Biotitoxidation ist relativ schnell: log J = -11 molmin/(m2 s). Berechnete Oxidationsraten auf der corestone-Skala (cm) sind vergleichbar zu Auflöseraten auf derselben Skala: log R = -13 molpx/(m2 s) und log R = -15 molbt/(m2 s). Volumetrische Berechnungen führen zum Schluss, dass die Oxidation mit einhergehender Volumenzunahme zur Entwicklung von Mikrofrakturen in den Mineralen und dem Gesamtgestein führt. Diese begünstigen Fluidtransport und damit einhergehende Plagioklasverwitterung. Des Weiteren ist diese Oxidationsreaktion verantwortlich für die Entstehung der Frakturen bei spheroidaler Verwitterung des Gesteins, welche die „rindlets“ vom „corestone“ abgrenzen. Daraus kann geschlossen werden, dass in situ Oxidation der ratenlimitierende Prozess bei der Verwitterung ist. Plagioklasverwitterung führt zu einer hohen Porositätszunahme und der endgültigen Umwandlung von Gestein zu Saprolit. Da Oxidation die erste Verwitterungsreaktion ist, verbinden die Zuführung und der Verbrauch von O2 zur, beziehungsweise an die Verwitterungsfront Erosion an der Oberfläche mit Prozessen an der Verwitterungsfront über einen Feedbackmechanismus. Daher hängt die langsame Verwitterungsrate letztlich vom Sauerstofftransport durch das Verwitterungsprofil und von lithologischen Faktoren des Charnockit wie zum Beispiel geringe Gesteinsporosität und/oder wenige Fe(II)-haltige Primärminerale ab. Des Weiteren ist der einzige Prozess im Charnockit der frische verwitterbare Oberflächen (eine Voraussetzung für chemische Verwitterung) generiert die oxidations-induzierte Frakturierung. Darüber hinaus minimieren die Abwesenheit von tektonischer Aktivität und geringe prä-anthropogene Erosionsraten in dieser Region den Abtrag des mächtigen und kohäsiven Verwitterungsprofils und somit über den beschriebenen Feedback auch die chemische Verwitterungsrate.

T1 - Chemical fingerprints of hydrological compartments and flow paths at La Cuenca, western Amazonia
N2 - A forested first-order catchment in western Amazonia was monitored for 2 years to determine the chemical fingerprints of precipitation, throughfall, overland flow, pipe flow, soil water, groundwater, and streamflow. We used five tracers (hydrogen, calcium, magnesium, potassium, and silica) to distinguish “fast” flow paths mainly influenced by the biological subsystem from “slow” flow paths in the geochemical subsystem. The former comprise throughfall, overland flow, and pipe flow and are characterized by a high potassium/silica ratio; the latter are represented by soil water and groundwater, which have a low potassium/silica ratio. Soil water and groundwater differ with respect to calcium and magnesium. The groundwater-controlled streamflow chemistry is strongly modified by contributions from fast flow paths during precipitation events. The high potassium/silica ratio of these flow paths suggests that the storm flow response at La Cuenca is dominated by event water.

T1 - Clumping effects on non-thermal particle spectra in massive star systems
N2 - Observational evidence exists that winds of massive stars are clumped. Many massive star systems are known as non-thermal particle production sites, as indicated by their synchrotron emission in the radio band. As a consequence they are also considered as candidate sites for non-thermal high-energy photon production up to gamma-ray energies. The present work considers the effects of wind clumpiness expected on the emitting relativistic particle spectrum in colliding wind systems, built up from the pool of thermal wind particles through diffusive particle acceleration, and taking into account inverse Compton and synchrotron losses. In comparison to a homogeneous wind, a clumpy wind causes flux variations of the emitting particle spectrum when the clump enters the wind collision region. It is found that the spectral features associated with this variability moves temporally from low to high energy bands with the time shift between any two spectral bands being dependent on clump size, filling factor, and the energy-dependence of particle energy gains and losses.

N2 - The mass loss rates and other parameters for a large sample of Galactic WN stars have been revised by Hamann et al. (2006), using the most up-to date Potsdam Wolf-Rayet (PoWR) model atmospheres. For a sub-sample of these stars exist measurements of their radio free-free emission. After harmonizing the adopted distance and terminal wind velocities, we compare the mass loss rates obtained from the two diagnostics. The differences are discussed as a possible consequence of different clumping contrast in the line-forming and radio-emitting regions.

T1 - Clumping in O-type Supergiants
N2 - We have analyzed the spectra of seven Galactic O4 supergiants, with the NLTE wind code CMFGEN. For all stars, we have found that clumped wind models match well lines from different species spanning a wavelength range from FUV to optical, and remain consistent with Hα data. We have achieved an excellent match of the P V λλ1118, 1128 resonance doublet and N IV λ1718, as well as He II λ4686 suggesting that our physical description of clumping is adequate. We find very small volume filling factors and that clumping starts deep in the wind, near the sonic point. The most crucial consequence of our analysis is that the mass loss rates of O stars need to be revised downward significantly, by a factor of 3 and more compared to those obtained from smooth-wind models.

Particular emphasis will be given to the clumping factors derived by means of optical lines (Hα and Heii 4686) and “classic” FUV (and UV) lines.

T1 - Constraint-based abstraction of a model checker for infinite state systems
N2 - Abstract interpretation-based model checking provides an approach to verifying properties of infinite-state systems. In practice, most previous work on abstract model checking is either restricted to verifying universal properties, or develops special techniques for temporal logics such as modal transition systems or other dual transition systems. By contrast we apply completely standard techniques for constructing abstract interpretations to the abstraction of a CTL semantic function, without restricting the kind of properties that can be verified. Furthermore we show that this leads directly to implementation of abstract model checking algorithms for abstract domains based on constraints, making use of an SMT solver.

T1 - Constraints on wind clumping from the empirical mass-loss vs. metallicity relation for early-type stars
N2 - We present the latest results on the observational dependence of the mass-loss rate in stellar winds of O and early-B stars on the metal content of their atmospheres, and compare these with predictions. Absolute empirical rates for the mass loss of stars brighter than 10$^{5.2} L_{\odot}$, based on H$\alpha$ and ultraviolet (UV) wind lines, are found to be about a factor of two higher than predictions. If this difference is attributed to inhomogeneities in the wind this would imply that luminous O and early-B stars have clumping factors in their H$\alpha$ and UV line forming regime of about a factor of 3--5. The investigated stars cover a metallicity range $Z$ from 0.2 to 1 $Z_{\odot}$. We find a hint towards smaller clumping factors for lower $Z$. The derived clumping factors, however, presuppose that clumping does not impact the predictions of the mass-loss rate. We discuss this assumption and explain how we intend to investigate its validity in more detail.

N2 - A new method is used in an eye-tracking pilot experiment which shows that it is possible to detect differences in common ground associated with the use of minimally different types of indefinite anaphora. Following Richardson and Dale (2005), cross recurrence quantification analysis (CRQA) was used to show that the tandem eye movements of two Swedish-speaking interlocutors are slightly more coupled when they are using fully anaphoric indefinite expressions than when they are using less anaphoric indefinites. This shows the potential of CRQA to detect even subtle processing differences in ongoing discourse.

T1 - Cue validity and sentence interpretation in English, German, and Italian
N2 - Linguistic and psycholinguistic accounts based on the study of English may prove unreliable as guides to sentence processing in even closely related languages. The present study illustrates this claim in a test of sentence interpretation by German-, Italian-, and English-speaking adults. Subjects were presented with simple transitive sentences in which contrasts of (1) word order, (2) agreement, (3) animacy, and (4) stress were systematically varied. For each sentence, subjects were asked to state which of the two nouns was the actor. The results indicated that Americans relied overwhelming on word order, using a first-noun strategy in NVN and a second-noun strategy in VNN and NNV sentences. Germans relied on both agreement and animacy. Italians showed extreme reliance on agreement cues. In both German and Italian, stress played a role in terms of complex interactions with word order and agreement. The findings were interpreted in terms of the “competition model” of Bates and MacWhinney (in H. Winitz (Ed.), Annals of the New York Academy of Sciences Conference on Native and Foreign Language Acquisition. New York: New York Academy of Sciences, 1982) in which cue validity is considered to be the primary determinant of cue strength. According to this model, cues are said to be high in validity when they are also high in applicability and reliability.

N2 - Pirates are fortune-seeking fighters at sea. Their exploits fire the imaginations of their victims and admirers, drawing a veil over individuals who rarely bear a real name and pursue their adventurous occupations as buccaneers, filibusters, freebooters, privateers, pirates, or corsairs. Piracy, corsairing, and contraband trade were epidemic among the Egyptians and the Phoenicians, the Greeks and the Vikings, the Spaniards and the Ottomans, the Muslims, and the Christians. And the Jews.

T1 - Detection of early cognitive processing by event-related phase synchronization analysis
N2 - In order to investigate the temporal characteristics of cognitive processing, we apply multivariate phase synchronization analysis to event-related potentials. The experimental design combines a semantic incongruity in a sentence context with a physical mismatch (color change). In the ERP average, these result in an N400 component and a P300-like positivity, respectively. The synchronization analysis shows an effect of global desynchronization in the theta band around 288ms after stimulus presentation for the semantic incongruity, while the physical mismatch elicits an increase of global synchronization in the alpha band around 204ms. Both of these effects clearly precede those in the ERP average. Moreover, the delay between synchronization effect and ERP component correlates with the complexity of the cognitive processes.

T1 - Developing a finite-state morphological analyzer for Urdu and Hindi
N2 - We introduce and discuss a number of issues that arise in the process of building a finite-state morphological analyzer for Urdu, in particular issues with potential ambiguity and non-concatenative morphology. Our approach allows for an underlyingly similar treatment of both Urdu and Hindi via a cascade of finite-state transducers that transliterates the very different scripts into a common ASCII transcription system. As this transliteration system is based on the XFST tools that the Urdu/Hindi common morphological analyzer is also implemented in, no compatibility problems arise.

T1 - Development of phonetic memory in disabled and normal readers
N2 - The development of phonetic codes in memory of 141 pairs of normal and disabled readers from 7.8 to 16.8 years of age was tested with a task adapted from L. S. Mark, D. Shankweiler, I. Y. Liberman, and C. A. Fowler (Memory & Cognition, 1977, 5, 623–629) that measured false-positive errors in recognition memory for foil words which rhymed with words in the memory list versus foil words that did not rhyme. Our younger subjects replicated Mark et al., showing a larger difference between rhyming and nonrhyming false-positive errors for the normal readers. The older disabled readers' phonetic effect was comparable to that of the younger normal readers, suggesting a developmental lag in their use of phonetic coding in memory. Surprisingly, the normal readers' phonetic effect declined with age in the recognition task, but they maintained a significant advantage across age in the auditory WISC-R digit span recall test, and a test of phonological nonword decoding. The normals' decline with age in rhyming confusion may be due to an increase in the precision of their phonetic codes.

T1 - Dialogue pressures and syntactic change
N2 - On the basis of the Dynamic Syntax framework, this paper argues that the production pressures in dialogue determining alignment effects and given versus new informational effects also drive the shift from case-rich free word order systems without clitic pronouns into systems with clitic pronouns with rigid relative ordering. The paper introduces assumptions of Dynamic Syntax, in particular the building up of interpretation through structural underspecification and update, sketches the attendant account of production with close coordination of parsing and production strategies, and shows how what was at the Latin stage a purely pragmatic, production-driven decision about linear ordering becomes encoded in the clitics in theMedieval Spanish system which then through successive steps of routinization yield the modern systems with immediately pre-verbal fixed clitic templates.

T1 - Do clumping corrections increase with decreasing mass-loss rates?
N2 - We report on new mass-loss rate estimates for O stars in six massive binaries using the amplitude of orbital-phase dependent, linear-polarimetric variability caused by electron scattering off free electrons in the winds. Our estimated mass-loss rates for luminous O stars are independent of clumping. They suggest similar clumping corrections as for WR stars and do not support the recently proposed reduction in mass-loss rates of O stars by one or two orders of magnitude.

T1 - Does subsidized care for toddlers increase maternal labor supply?
BT - Evidence from a large-scale expansion of early childcare
T2 - CEPA Discussion Papers
N2 - Expanding public or publicly subsidized childcare has been a top social policy priority in many industrialized countries. It is supposed to increase fertility, promote children’s development and enhance mothers’ labor market attachment. In this paper, we analyze the causal effect of one of the largest expansions of subsidized childcare for children up to three years among industrialized countries on the employment of mothers in Germany. Identification is based on spatial and temporal variation in the expansion of publicly subsidized childcare triggered by two comprehensive childcare policy reforms. The empirical analysis is based on the German Microcensus that is matched to county level data on childcare availability. Based on our preferred specification which includes time and county fixed effects we find that an increase in childcare slots by one percentage point increases mothers’ labor market participation rate by 0.2 percentage points. The overall increase in employment is explained by the rise in part-time employment with relatively long hours (20-35 hours per week). We do not find a change in full-time employment or lower part-time employment that is causally related to the childcare expansion. The effect is almost entirely driven by mothers with medium-level qualifications. Mothers with low education levels do not profit from this reform calling for a stronger policy focus on particularly disadvantaged groups in coming years.

T1 - Dynamical simulation of the “velocity-porosity” reduction in observed strength of stellar wind lines
N2 - I use dynamical simulations of the line-driven instability to examine the potential role of the resulting flow structure in reducing the observed strength of wind absorption lines. Instead of the porosity length formalism used to model effects on continuum absorption, I suggest reductions in line strength can be better characterized in terms of a velocity clumping factor that is insensitive to spatial scales. Examples of dynamic spectra computed directly from instability simulations do exhibit a net reduction in absorption, but only at a modest 10-20% level that is well short of the ca. factor 10 required by recent analyses of PV lines.

JF - Potsdamer Beiträge zur Hochschulforschung
N2 - During the National Multiplication Training in Kenya in 2018, participants raised concerns about attrition, completion rates and quality of PhD programmes in Kenya’s public universities. This led the authors of this article to further examine the question of PhD completion rates. Available data underlined that PhD students across various disciplines in Kenya’s public universities take unnecessarily long to complete their studies due to a myriad of factors that are related to their supervisors, university guidelines for post-graduate studies, or the students themselves. This article examines inertia areas along the PhD training pathway at three public universities in Kenya and provides suggestions on structural and operational changes universities must make to shorten completion periods.

We present not only a short description of each considered environment and the taxonomy in the form of a table, but also our understanding and opinions on how and why the environments implement the same concepts and ideas in different ways and which concepts and ideas seem to be important to the creators of such environments.

T1 - Eta Carinae viewed from different vantages
N2 - The spatially-resolved winds of the massive binary, Eta Carinae, extend an arcsecond on the sky, well beyond the 10 to 20 milliarcsecond binary orbital dimension. Stellar wind line profiles, observed at very different angular resolutions of VLTI/AMBER, HST/STIS and VLT/UVES, provide spatial information on the extended wind interaction structure as it changes with orbital phase. These same wind lines, observable in the starlight scattered off the foreground lobe of the dusty Homunculus, provide time-variant line profiles viewed from significantly different angles. Comparisons of direct and scattered wind profiles observed in the same epoch and at different orbital phases provide insight on the extended wind structure and promise the potential for three-dimensional imaging of the outer wind structures. Massive, long-lasting clumps, including the nebularWeigelt blobs, originated during the two historical ejection events. Wind interactions with these clumps are quite noticeable in spatially-resolved spectroscopy. As the 2009.0 minimum approaches, analysis of existing spectra and 3-D modeling are providing bases for key observations to gain further understanding of this complex massive binary.

T1 - Existential quantifiers in the rule body
N2 - In this paper we consider a simple syntactic extension of Answer Set Programming (ASP) for dealing with (nested) existential quantifiers and double negation in the rule bodies, in a close way to the recent proposal RASPL-1. The semantics for this extension just resorts to Equilibrium Logic (or, equivalently, to the General Theory of Stable Models), which provides a logic-programming interpretation for any arbitrary theory in the syntax of Predicate Calculus. We present a translation of this syntactic class into standard logic programs with variables (either disjunctive or normal, depending on the input rule heads), as those allowed by current ASP solvers. The translation relies on the introduction of auxiliary predicates and the main result shows that it preserves strong equivalence modulo the original signature.

N2 - The emergence of information extraction (IE) oriented pattern engines has been observed during the last decade. Most of them exploit heavily finite-state devices. This paper introduces ExPRESS – a new extraction pattern engine, whose rules are regular expressions over flat feature structures. The underlying pattern language is a blend of two previously introduced IE oriented pattern formalisms, namely, JAPE, used in the widely known GATE system, and the unificationbased XTDL formalism used in SProUT. A brief and technical overview of ExPRESS, its pattern language and the pool of its native linguistic components is given. Furthermore, the implementation of the grammar interpreter is addressed too.

T1 - Extraterritorial Constitutional Rights
BT - A Comparative Case Study of the United States and Germany
JF - MenschenRechtsMagazin
N2 - Im Laufe der vergangenen Jahrzehnte widmeten Lehre und Rechtsprechung der extraterritorialen Anwendbarkeit von Menschenrechtsabkommen erhebliche Aufmerksamkeit. Im Gegensatz fand die extraterritoriale Anwendung verfassungsgesetzlich verankerter Grundrechte nur in den Vereinigten Staaten vergleichbares akademisches Interesse. Insbesondere lässt sich ein Mangel an vergleichender Forschung in diesem Bereich feststellen, was zur herrschenden Meinung beiträgt, dass internationale Menschenrechtskonventionen den geeigneten Rahmen bieten, unter dem inländische Gerichte extraterritoriale Fragen des Verfassungsrechts prüfen sollten.
Dieser Artikel argumentiert, dass inländische verfassungsrechtliche Regelungen und die zu ihrer Durchsetzung zuständigen Gerichte ein wichtiges Gegengewicht in der festgefahrenen internationalen Extraterritorialitätsdebatte spielen sollten. Anhand zweier Fallstudien aus Deutschland und den Vereinigten Staaten wird gezeigt, dass inländische Verfassungsgerichte manchmal besser geeignet sind als Vertragsorgane, um die Grundwerte der Menschenwürde und der Universalität im extraterritorialen Kontext zu wahren. Dies zeigt sich besonders deutlich am Beispiel Deutschlands, das über eine lange Tradition der Integration in internationale Mehrebenensysteme und des grundrechtliche "Bottom-up"-Widerstands innerhalb solcher Systeme verfügt. Aktuelle Fälle des Bundesverfassungsgerichts zur extraterritorialen Anwendung des Grundgesetzes auf ausländische nachrichtendienstliche Aktivitäten und Klimawandel unterstützen diese Theorie. Allerdings kann ein unabhängiger verfassungsrechtlicher Ansatz auch in solchen nationalen Systemen eigenständige normative Effekte erzielen, welche stärker vom internationalen Menschenrechtssystem isoliert sind. So verwendete auch der amerikanische Oberste Gerichtshof (Supreme Court) die inländische verfassungsrechtliche Doktrin, um die streng territoriale Auslegung des Internationalen Pakts über bürgerliche und politische Rechte durch die amerikanische Regierung zu umgehen und einen funktionalen Ansatz für die extraterritoriale Anwendbarkeit von Grundrechten im Fall der Inhaftierung mutmaßlicher Terroristen im Marinestützpunkt von Guantánamo Bay zu nutzen.
Die Untersuchung dieser Beispiele beansprucht nicht, umfassend oder repräsentativ die vielfältigen Verfassungen der Welt und ihre Beziehungen zu völkerrechtlichen Menschenrechtsnormen zu untersuchen. Dennoch sollte die unabhängige Wirkung von verfassungsrechtlichen Rahmenbedingungen in diesen beiden disparaten Fällen umso mehr Anreiz für eine verstärkte vergleichende Forschung zu verfassungsrechtlichen Extraterritorialitätsregimen und ihrem Beitrag zum Projekt der Menschenrechte bieten.
N2 - In the past decades, scholars and courts have paid considerable attention to the extraterritorial applicability of human rights treaties. By contrast, the extraterritorial application of constitutional rights has received comparable scholarly attention only in the United States. Specifically, there is a paucity of comparative research in this area, which contributes to the prevailing view that human rights law provides the proper framework under which domestic courts should examine extraterritoriality questions under constitutional law.
This article argues that domestic constitutional regimes and their judicial enforcers can and should provide an important counterweight to the deadlocked extraterritoriality debate at the international level. Using two case studies from Germany and the United States, it shows that domestic constitutional courts are sometimes better suited than treaty bodies to guard the normative values of human dignity and universality in an extraterritoriality context. This is most apparent in the case of Germany, which has a long tradition of integration into international multi-level governance systems and "bottom-up" resistance based on fundamental rights within such systems. Recent cases from the Federal Constitutional Court (Bundesverfassungsgericht) about the extraterritorial application of the Basic Law (Grundgesetz) to foreign intelligence gathering and climate change support this theory. However, an independent constitutional approach can also achieve some normative effects in domestic systems that are more isolated from the international human rights system. Thus, the US Supreme Court likewise used domestic constitutional doctrine to sidestep the American government's strictly territorial interpretation of the ICCPR and employ a functional approach to the extraterritorial applicability of fundamental rights in the case of detention of suspected terrorists in the Guantánamo Bay naval base.
The study of these two examples does not purport to be comprehensive or even representative of the world’s diverse array of constitutions and their relationships with international human rights law. However, the independent power of constitutional frameworks in these two disparate cases should all the more provide an impetus for increased comparative research into constitutional extraterritoriality regimes and their value for the project of human rights.

T1 - Far-ultraviolet spectroscopy of O+O binaries in the Magellanic Clouds
N2 - We report FUSE observations in 2005–2006 of three O-type, double-lined spectroscopic binaries in the Magellanic Clouds. The systems have very short periods (1.4–2.25 d), represent rare, young evolutionary stages of massive stars and binaries, and provide a unique glimpse at some of the most massive systems that form in dense clusters of massive stars. Improved orbit parameters, including revised masses, for LH54-425 are derived from new ctio spectroscopy. The systems are: LH54-425 in the LMC (O3V + O5V, P=2.25d, 62+37M⊙), J053441-693139 in the LMC (O2-3If+O6V, P=1.4 d, 41+27M⊙), and Hodge 53-47 in the SMC (O6V + O4-5IIIf, P=2.2 d, 24+14M⊙, where the O4 star appears to be less massive than the O6 star). Their short periods indicates that wind interaction and mass transfer are likely important factors in their evolution. The spectra provide quantitative and systematic studies of phase-dependent stellar wind properties, wind collision effects in O+O binaries at lower metallicities, improved radial velocity curves, and FUV spectro-photometric changes as a function of orbital phase.

Whereas usual two-level grammars describe rational sets over symbol pairs, this new formalism uses tree structured regular expressions. They allow an explicit and precise definition of the scope of feature structures. A given surface form may be described using several feature structures. Feature unification is expressed in contextual rules using variables, like in a unification grammar. Grammars are compiled in finite state multi-tape transducers.

T1 - Focus and intonation in Japanese
BT - Does focus trigger pitch reset?
JF - Interdisciplinary studies on information structure : ISIS ; working papers of the SFB 632
N2 - This paper discusses how focus changes prosodic structure in Tokyo Japanese. It is generally believed that focus blocks the intonational process of downstep and causes a pitch reset. This paper presents experimental evidence against this traditional view by looking at the prosodic behavior of Wh words, which receive focus lexically in Japanese as in other languages. It is demonstrated, specifically, that the focused Wh element does not block downstep although it receives a much higher pitch than its preceding element. This suggests that presence of lexical focus does not trigger pitch reset in Japanese.

JF - Interdisciplinary studies on information structure : ISIS ; working papers of the SFB 632
N2 - We argue that the standard focus theories reach their limits when confronted with the focus systems of the Chadic languages. The backbone of the standard focus theories consists of two assumptions, both called into question by the languages under consideration. Firstly, it is standardly assumed that focus is generally marked by stress. The Chadic languages, however, exhibit a variety of different devices for focus marking. Secondly, it is assumed that focus is always marked. In Tangale, at least, focus is not marked consistently on all types of constituents. The paper offers two possible solutions to this dilemma.

T1 - Formal semantics for iconic gesture
N2 - We present a formal analysis of iconic coverbal gesture. Our model describes the incomplete meaning of gesture that’s derivable from its form, and the pragmatic reasoning that yields a more specific interpretation. Our formalism builds on established models of discourse interpretation to capture key insights from the descriptive literature on gesture: synchronous speech and gesture express a single thought, but while the form of iconic gesture is an important clue to its interpretation, the content of gesture can be resolved only by linking it to its context.

T1 - From complex to simple speech acts : a bidimensional analysis of illocutionary
N2 - We present a new analysis of illocutionary forces in dialogue. We analyze them as complex conversational moves involving two dimensions: what Speaker commits herself to and what she calls on Addressee to perform. We start from the analysis of speech acts such as confirmation requests or whimperatives, and extend the analysis to seemingly simple speech acts, such as statements and queries. Then, we show how to integrate our proposal in the framework of the Grammar for Conversation (Ginzburg, to app.), which is adequate for modelling agents' information states and how they get updated.

T1 - From satellite imagery to soil-plant interactions
BT - integrating disciplines and scales in process based simulation models
N2 - Decisions for the conservation of biodiversity and sustainable management of natural resources are typically related to large scales, i.e. the landscape level. However, understanding and predicting the effects of land use and climate change on scales relevant for decision-making requires to include both, large scale vegetation dynamics and small scale processes, such as soil-plant interactions. Integrating the results of multiple BIOTA subprojects enabled us to include necessary data of soil science, botany, socio-economics and remote sensing into a high resolution, process-based and spatially-explicit model. Using an example from a sustainably-used research farm and a communally used and degraded farming area in semiarid southern Namibia we show the power of simulation models as a tool to integrate processes across disciplines and scales.

T1 - Functional elements in infants’ speech processing : the role of determiners in the syntactic categorization of lexical elements
N2 - How do children determine the syntactic category of novel words? In this article we present the results of 2 experiments that investigated whether German children between 12 and 16 months of age can use distributional knowledge that determiners precede nouns and subject pronouns precede verbs to syntactically categorize adjacent novel words. Evidence from the head-turn preference paradigm shows that, although 12- to 13-month-olds cannot do this, 14- to 16-month-olds are able to use a determiner to categorize a following novel word as a noun. In contrast, no categorization effect was found for a novel word following a subject pronoun. To understand this difference we analyzed adult child-directed speech. This analysis showed that there are in fact stronger co-occurrence relations between determiners and nouns than between subject pronouns and verbs. Thus, in German determiners may be more reliable cues to the syntactic category of an adjacent novel word than are subject pronouns. We propose that the capacity to syntactically categorize novel words, demonstrated here for the first time in children this young, mediates between the recognition of the specific morphosyntactic frame in which a novel word appears and the word-to-world mapping that is needed to build up a semantic representation for the novel word.

T1 - Geohistory of the Central Anatolian Plateau southern margin (southern Turkey)
T1 - Die geologische Entwicklung des südlichen zentralsanatolischen Plateaurandes (Süd-Türkei)
N2 - The Adana Basin of southern Turkey, situated at the SE margin of the Central Anatolian Plateau is ideally located to record Neogene topographic and tectonic changes in the easternmost Mediterranean realm. Using industry seismic reflection data we correlate 34 seismic profiles with corresponding exposed units in the Adana Basin. The time-depth conversion of the interpreted seismic profiles allows us to reconstruct the subsidence curve of the Adana Basin and to outline the occurrence of a major increase in both subsidence and sedimentation rates at 5.45 – 5.33 Ma, leading to the deposition of almost 1500 km3 of conglomerates and marls. Our provenance analysis of the conglomerates reveals that most of the sediment is derived from and north of the SE margin of the Central Anatolian Plateau. A comparison of these results with the composition of recent conglomerates and the present drainage basins indicates major changes between late Messinian and present-day source areas. We suggest that these changes in source areas result of uplift and ensuing erosion of the SE margin of the plateau. This hypothesis is supported by the comparison of the Adana Basin subsidence curve with the subsidence curve of the Mut Basin, a mainly Neogene basin located on top of the Central Anatolian Plateau southern margin, showing that the Adana Basin subsidence event is coeval with an uplift episode of the plateau southern margin. The collection of several fault measurements in the Adana region show different deformation styles for the NW and SE margins of the Adana Basin. The weakly seismic NW portion of the basin is characterized by extensional and transtensional structures cutting Neogene deposits, likely accomodating the differential uplift occurring between the basin and the SE margin of the plateau. We interpret the tectonic evolution of the southern flank of the Central Anatolian Plateau and the coeval subsidence and sedimentation in the Adana Basin to be related to deep lithospheric processes, particularly lithospheric delamination and slab break-off.
N2 - Il Bacino di Adana (Turchia meridionale) é situato in posizione esterna rispetto al margine sud-orientale del plateau anatolico centrale. Il bacino risulta ubicato in posizione strategica per registrare i principali cambiamenti della topografia e dell’assetto tettonico avvenuti durante il Neogene nel Mediterraneo orientale. Utilizzando dati sismici provenienti dall’industria petrolifera abbiamo correlato 34 profili sismici con le unitá corrispondenti affioranti nel Bacino di Adana. La conversione da tempi a profonditá dei profili sismici interpretati ci ha permesso di ricostruire la curva di subsidenza del Bacino di Adana e di individuare un evento caratterizato da un importante aumento della subsidenza associato ad un considerevole incremento del tasso di sedimentazione. Questo evento, avvenuto tra 5.45 e 5.33 Ma ha portato alla deposizione di quasi 1500 km3 di conglomerati e marne. La nostra analisi di provenienza della porzione conglomeratica mostra che la maggior parte del sedimento proviene dal margine sud-orientale del plateau anatolico centrale e dalle aree situate a nord di questo. La comparazione di questi risultati con la composizione litologica di conglomerati recenti e con le litologie affioranti nei bacini di drenaggio attuali mostra cambiamenti rilevanti tra le aree di provenienza del sedimento Messiniane e quelle attuali. Riteniamo che questi cambiamenti nelle aree sorgente siano il risultato del sollevamento e della successiva erosione del margine sud-orientale del plateau anatolico centrale. Questa ipotesi é supportata dal confronto delle curve di subsidenza del Bacino di Adana e del Bacino di Mut, un bacino principalmente neogenico situato sulla sommitá del margine meridionale del plateau. La comparazione delle due curve di subsidenza mostra che l’evento di forte subsidenza del Bacino di Adana é coevo ad un episodio di sollevamento del margine meridionale del plateau anatolico centrale. La raccolta di un fitto dataset strutturale acquisito nella regione di Adana mostra differenti stili deformativi per i margini nord-occidentale e sud-orientale del bacino. La porzione nord-occidentale del bacino, debolmente sismica, é caratterizzata da strutture estensionali e transtensive che tagliano I depositi neogenici, verosimilmente accomodando il sollevamento differenziale tra il bacino e il margine sud-orientale del plateau. Riteniamo che l’evoluzione tettonica del margine meridionale del plateau anatolico centrale e la contemporanea subsidenza e sedimentazione nel Bacino di Adana sia da ricondurre a processi litosferici profondi, in particolar modo delaminazione litosferica e slab break-off.

T1 - German strategic culture and the changing role of the Bundeswehr
N2 - The article mobilises the concept of strategic culture in order to identify the impact of history upon contemporary security policy. The article will first look at the "wholesale construction" of a strategic culture after the Second World War in West Germany before exploring its impact upon security policy since the end of the Cold War in two areas: the Bundeswehr's out-of-area role and conscription. The central argument presented here is that the strategic culture of the former Federal Republic now writ large on to the new united Germany sets the context within which security policies are designed. This strategic culture, as will be argued, acts as both a facilitating and a restraining variable on behaviour, making certain policy options possible and others impossible.

T1 - Goal-oriented dialog as a collaborative subordinated activity involving collective acceptance
N2 - Modeling dialog as a collaborative activity consists notably in specifying the contain of the Conversational Common Ground and the kind of social mental state involved. In previous work (Saget, 2006), we claim that Collective Acceptance is the proper social attitude for modeling Conversational Common Ground in the particular case of goal-oriented dialog. We provide a formalization of Collective Acceptance, besides elements in order to integrate this attitude in a rational model of dialog are provided; and finally, a model of referential acts as being part of a collaborative activity is provided. The particular case of reference has been chosen in order to exemplify our claims.

N2 - Central Europe is characterized by linguistic and cultural density as well as by endogenous and exogenous cultural influences. These constellations were especially visible in the former Habsburg Empire, where they influenced the formation of individual and collective identities. This led not only to continual crises and conflicts, but also to an equally enormous creative potential as became apparent in the culture of the fin-de-siècle.

T1 - Hate is too great a burden to bear
BT - Hate crimes and the mental health of refugees
T2 - CEPA Discussion Papers
N2 - Against a background of increasing violence against non-natives, we estimate the effect of hate crime on refugees’ mental health in Germany. For this purpose, we combine two datasets: administrative records on xenophobic crime against refugee shelters by the Federal Criminal Office and the IAB-BAMF-SOEP Survey of Refugees. We apply a regression discontinuity in time design to estimate the effect of interest. Our results indicate that hate crime has a substantial negative effect on several mental health indicators, including the Mental Component Summary score and the Patient Health Questionnaire-4 score. The effects are stronger for refugees with closer geographic proximity to the focal hate crime and refugees with low country-specific human capital. While the estimated effect is only transitory, we argue that negative mental health shocks during the critical period after arrival have important long-term consequences. Keywords: Mental health, hate crime, migration, refugees, human capital.

T1 - How to Promote and Measure Reflective Skills in Depth and Breadth of English and Physics Teacher Trainees
JF - Reflexion in der Lehrkräftebildung: Empirisch – Phasenübergreifend – Interdisziplinär (Potsdamer Beiträge zur Lehrerbildung und Bildungsforschung ; 4)
N2 - Supporting reflection in preservice during university-based training is, without doubt, a crucial aspect in attaining teacher professionalism. Therefore, an on-campus seminar designed to relate theory to practice and vice versa – the so-called ‘Lehr-Lern-Labor-Seminar (LLLS)’ – was implemented over the course of five terms to stimulate reflective skills of English and Physics teacher trainees. Investigations on the effectiveness of three types of the LLLS (no video and two types of video-supported reflections) compared to a parallel group (PG) and a control group (CG) occurred in a mixed methods quasi-experimental study. Reflective skills were elicited with vignettes, relevant covariates with questionnaires. Reflective development was then traced in the dimensions depth and breadth employing a qualitative content analysis. MANCOVA (Multivariate Analysis of Covariance) and regression analyses revealed a substantive increase of reflective depth for English and Physics teacher trainees and breadth development for English LLLS-participants in contrast to both, a PG and a CG, even when controlling for the subjects’ individual prerequisites.

T1 - Human Microsaccade-Related Visual Brain Responses
N2 - Microsaccades are very small, involuntary flicks in eye position that occur on average once or twice per second during attempted visual fixation. Microsaccades give rise to EMG eye muscle spikes that can distort the spectrum of the scalp EEG and mimic increases in gamma band power. Here we demonstrate that microsaccades are also accompanied by genuine and sizeable cortical activity, manifested in the EEG. In three experiments, high-resolution eye movements were corecorded with the EEG: during sustained fixation of checkerboard and face stimuli and in a standard visual oddball task that required the counting of target stimuli. Results show that microsaccades as small as 0.15° generate a field potential over occipital cortex and midcentral scalp sites 100 –140 ms after movement onset, which resembles the visual lambda response evoked by larger voluntary saccades. This challenges the standard assumption of human brain imaging studies that saccade-related brain activity is precluded by fixation, even when fully complied with. Instead, additional cortical potentials from microsaccades were present in 86% of the oddball task trials and of similar amplitude as the visual response to stimulus onset. Furthermore, microsaccade probability varied systematically according to the proportion of target stimuli in the oddball task, causing modulations of late stimulus-locked event-related potential (ERP) components. Microsaccades present an unrecognized source of visual brain signal that is of interest for vision research and may have influenced the data of many ERP and neuroimaging studies.

T1 - Hydrologic pathways and stormflow hydrochemistry at South Creek, northeast Queensland
N2 - Earlier investigations at South Creek in northeastern Queensland established the importance of overland flow as a hydrologic pathway in this tropical rainforest environment. Since this pathway is ‘fast’, transmitting presumably ‘new’ water, its importance should be reflected in the stormflow chemistry of South Creek: the greater the volumentric contribution to the stormflow hydrograph, the more similarity between the chemical composition of streamwater and of overland flow is to be expected. Water samples were taken during two storm events in an ephemeral gully (gully A), an intermittent gully (gully B) and at the South Creek catchment outlet; additional spot checks were made in several poorly defined rills. The chemical composition of ‘old’ water was determined from 45 baseflow samples collected throughout February. The two events differed considerably in their magnitudes, intensities and antecedent moisture conditions. In both events, the stormflow chemistry in South Creek was characterized by a sharp decrease in Ca, Mg, Na, Si, Cl, EC, ANC, alkalinity and total inorganic carbon. pH remained nearly constant with discharge, whereas K increased sharply, as did sulfate in an ill-defined manner. In event 1, this South Creek stormflow pattern was closely matched by the pattern in gully A, implying a dominant contribution of ‘new’ water. This match was confirmed by the spot samples from rills. Gully B behaved like South Creek itself, but with a dampened ‘new’ water signal, indicating less overland flow generation in its subcatchment. In event 2, which occurred five days later, the initial ‘new’ water signal in gully A was rapidly overwhelmed by a different signal which is attributed to rapid drainage from a perched water table. This study shows that stormflow in this rainforest catchment consists predominantly of ‘new’ water which reaches the stream channel via ‘fast’ pathways. Where the ephemeral gullies delivering overland flow are incised deeply enough to intersect a perched water table, a delayed, ‘old’ water-like signal may be transmitted.

T1 - Hα line profile variability in the B8Ia-type supergiant Rigel (β Ori)
N2 - Hα observations of Rigel obtained on 184 nights during the past ten years with the 1-m telescope and ´echelle spectrograph of Ritter Observatory are surveyed. The line profiles were classified in terms of morphology. About 1/4 of them are of P Cygni type, about 15% inverse P Cygni, about 25% double-peaked, about 1/3 pure absorption, and a few are single emission lines. Transformation of the profile from one type to another typically takes a few days. Although the line stays in absorption for extended intervals, only one high-velocity absorption event of the intensity reported by Kaufer et al. (1996a) was observed, in late 2006. Late in this event, Hα absorption occurred farther to the red than the red wing of a plausible photospheric absorption component, an indication of infalling material. In general, as the absorption events come to an end, the emission typically returns with an inverse P Cygni profile. The Hα profile class shows no obvious correlation with the radial velocity of C II λ6578, a photospheric absorption line.

N2 - In two experiments, many annotators marked antecedents for discourse deixis as unconstrained regions of text. The experiments show that annotators do converge on the identity of these text regions, though much of what they do can be captured by a simple model. Demonstrative pronouns are more likely than definite descriptions to be marked with discourse antecedents. We suggest that our methodology is suitable for the systematic study of discourse deixis.

T1 - Imaging and spectroscopy with the James Webb Space Telescope
N2 - The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope scheduled for launch in 2013. JWST will find the first stars and galaxies that formed in the early universe, connecting the Big Bang to our own Milky Way galaxy. JWST will peer through dusty clouds to see stars forming planetary systems, connecting the MilkyWay to our own Solar System. JWST’s instruments are designed to work primarily in the infrared range of 1 - 28 μm, with some capability in the visible range. JWST will have a large mirror, 6.5 m in diameter, and will be diffraction-limited at 2 μm (0.1 arcsec resolution). JWST will be placed in an L2 orbit about 1.5 million km from the Earth. The instruments will provide imaging, coronography, and multi-object and integral-field spectroscopy across the 1 - 28 μm wavelength range. The breakthrough capabilities of JWST will enable new studies of massive star winds from the Milky Way to the early universe.

N2 - Whilst providing a framework for learning and scientific emancipation, a proposal writing training is confronted with various organisational and didactic challenges, which influence the achievement of the set training objectives. Based on observations made during the workshops for proposal writing organised in Kinshasa, Democratic Republic of Congo, as part of the NMT Programme, the article raises two main questions: (a) How could these challenges be overcome and successfully addressed in the training? (b) What is the level of learning outcomes of the participants at the end of the training? The article shows that the success of the training lays in the relevance of the employed training approaches. The use of a participatory approach encouraged constructive exchanges between participants, trainers, and experts, and enabled all participants to finalise coherent projects to apply for national and international funding.

T1 - Improvement of a fluorescence immunoassay with a compact diode-pumped solid state laser at 315 nm
N2 - We demonstrate the improvement of fluorescence immunoassay (FIA) diagnostics in deploying a newly developed compact diode-pumped solid state (DPSS) laser with emission at 315 nm. The laser is based on the quasi-three-level transition in Nd:YAG at 946 nm. The pulsed operation is either realized by an active Q-switch using an electro-optical device or by introduction of a Cr4+:YAG saturable absorber as passive Q-switch element. By extra-cavity second harmonic generation in different nonlinear crystal media we obtained blue light at 473 nm. Subsequent mixing of the fundamental and the second harmonic in a β-barium-borate crystal provided pulsed emission at 315 nm with up to 20 μJ maximum pulse energy and 17 ns pulse duration. Substitution of a nitrogen laser in a FIA diagnostics system by the DPSS laser succeeded in considerable improvement of the detection limit. Despite significantly lower pulse energies (7 μJ DPSS laser versus 150 μJ nitrogen laser), in preliminary investigations the limit of detection was reduced by a factor of three for a typical FIA.

T1 - In Search of Belonging
BT - Galician Jewish Immigrants Between New York and Eastern Europe, 1890–1938

N2 - More than 200,000 Jews left the Habsburg province of Galicia between 1881 and 1910. No longer living in the places of their childhood, they settled in urban centers, such as in New York’s Lower East Side. In this neighborhood, Galician Jews began to search for new relationships that linked the places they left and the ones where they arrived and settled. By looking at Galicia through the lens of autobiographical writings by former Jewish immigrants who became established residents of New York, this article emphasizes the role of regionalism in the context of transnational conceptions of a new American Jewish self-understanding. It argues that the key to analyzing the evolution of “eastern Europe” as a common place of origin for American Jewry is the constant dialogue between the places of origin and arrival. Specifically, philanthropic efforts during and after the First World War and the proliferation of tourism both enabled these settled immigrants to gradually replace regional notions, such as the idea of Galicia, with a mythical image of eastern Europe to create a sense of community as American Jews.

T1 - Increase in prostanoid formation in rat liver macrophages (Kupffer cells) by human anaphylatoxin C3a
N2 - Human anaphylatoxin C3a increases glycogenolysis in perfused rat liver. This action is inhibited by prostanoid synthesis inhibitors and prostanoid antagonists. Because prostanoids but not anaphylatoxin C3a can increase glycogenolysis in hepatocytes, it has been proposed that prostanoid formation in nonparenchymal cells represents an important step in the C3a-dependent increase in hepatic glycogenolysis. This study shows that (a) human anaphylatoxin C3a (0.1 to 10 mug/ml) dose-dependently increased prostaglandin D2, thromboxane B, and prostaglandin F2alpha formation in rat liver macrophages (Kupffer cells); (b) the C3a-mediated increase in prostanoid formation was maximal after 2 min and showed tachyphylaxis; and (c) the C3a-elicited prostanoid formation could be inhibited specifically by preincubation of C3a with carboxypeptidase B to remove the essential C-terminal arginine or by preincubation of C3a with Fab fragments of a neutralizing monoclonal antibody. These data support the hypothesis that the C3a-dependent activation of hepatic glycogenolysis is mediated by way of a C3a-induced prostanoid production in Kupffer cells.

T1 - Increase of glucose and lactate output and decrease of flow by human anaphylatoxin C3a but not C5a in perfused rat liver
N2 - The complement fragments C3a and C5a were purified from zymosan-activated human serum by column chromatographic procedures after the bulk of the proteins had been removed by acidic polyethylene glycol precipitation. In the isolated in situ perfused rat liver C3a increased glucose and lactate output and reduced flow. Its effects were enhanced in the presence of the carboxypeptidase inhibitor DL-mercaptomethyl-3-guanidinoethylthio-propanoic acid (MERGETPA) and abolished by preincubation of the anaphylatoxin with carboxypeptidase B or with Fab fragments of an anti-C3a monoclonal antibody. The C3a effects were partially inhibited by the thromboxane antagonist BM13505. C5a had no effect. It is concluded that locally but not systemically produced C3a may play an important role in the regulation of local metabolism and hemodynamics during inflammatory processes in the liver.

T1 - Increase of urate formation by stimulation of sympathetic hepatic nerves, circulating noradrenaline and glucagon inthe perfused rat liver
N2 - In the isolated rat liver perfused in situ stimulation of the nerve bundles around the portal vein and the hepatic artery caused an increase of urate formation that was inhibited by the α1-blocker prazosine and the xanthine oxidase inhibitor allopurinol. Moreover, nerve stimulation increased glucose and lactate output and decreased perfusion flow. Infusion of noradrenaline had similar effects. Compared to nerve stimulation infusion of glucagon led to a less pronounced increase of urate formation and a twice as large increase in glucose output but a decrease in lactate release without affecting the flow rate. Insulin had no effect on any of the parameters studied.

T1 - Independent signs of lower mass-loss rates for O-type stars
N2 - I discuss observational evidence – independent of the direct spectral diagnostics of stellar winds themselves – suggesting that mass-loss rates for O stars need to be revised downward by roughly a factor of three or more, in line with recent observed mass-loss rates for clumped winds. These independent constraints include the large observed mass-loss rates in LBV eruptions, the large masses of evolved massive stars like LBVs and WNH stars, WR stars in lower metallicity environments, observed rotation rates of massive stars at different metallicity, supernovae that seem to defy expectations of high mass-loss rates in stellar evolution, and other clues. I pay particular attention to the role of feedback that would result from higher mass-loss rates, driving the star to the Eddington limit too soon, and therefore making higher rates appear highly implausible. Some of these arguments by themselves may have more than one interpretation, but together they paint a consistent picture that steady line-driven winds of O-type stars have lower mass-loss rates and are significantly clumped.

T1 - Inequality of Opportunity in Wealth
BT - Levels, Trends, and Drivers
T2 - CEPA Discussion Papers
N2 - While inequality of opportunity (IOp) in earnings is well studied, the literature on IOp in individual net wealth is scarce to non-existent. This is problematic because both theoretical and empirical evidence show that the position in the wealth and income distribution can significantly diverge.We measure ex-ante IOp in net wealth for Germany using data from the Socio-Economic Panel (SOEP). Ex-ante IOp is defined as the contribution of circumstances to the inequality in net wealth before effort is exerted. The SOEP allows for a direct mapping from individual circumstances to individual net wealth and for a detailed decomposition of net wealth inequality into a variety of circumstances; among them childhood background, intergenerational transfers, and regional characteristics. The ratio of inequality of opportunity to total inequality is stable from 2002 to 2019. This is in sharp contrast to labor earnings, where ex-ante IOp is declining over time. Our estimates suggest that about 62% of the inequality in net wealth is due to circumstances. The most important circumstances are intergenerational transfers, parental occupation, and the region of birth. In contrast, gender and individuals’ own education are the most important circumstances for earnings.

JF - PaRDeS : Journal of the Association for Jewish Studies in Germany
JF - PaRDeS : Zeitschrift der Vereinigung für Jüdische Studien
N2 - When the Jewish Theological Seminary in Breslau opened its doors in 1854, it established a novel form of rabbinical education: the systematic combination of Jewish studies at the seminary in parallel with university studies. The Breslau seminary became the model for most later institutions for rabbinical training in Europe and the United States. The seminaries were the new sites of modern Jewish scholarship, especially the academic study of Judaism (Wissenschaft des Judentums). Their function and goal were to preserve, (re)organize, and transmit Jewish knowledge in the modern age. As such, they became central nodes in Jewish scholarly networks. This case study highlights the multi-nodal connections between the Conservative seminaries in Breslau, Philadelphia, New York, Budapest, and Vienna. At the same time, it is intended to provide an example of the potential of transnational and transfer studies for the history of the Jewish religious learning in Europe and the United States.

T1 - Integration of digital elevation models and satellite images to investigate geological processes.
N2 - In order to better understand the geological boundary conditions for ongoing or past surface processes geologists face two important questions: 1) How can we gain additional knowledge about geological processes by analyzing digital elevation models (DEM) and satellite images and 2) Do these efforts present a viable approach for more efficient research. Here, we will present case studies at a variety of scales and levels of resolution to illustrate how we can substantially complement and enhance classical geological approaches with remote sensing techniques. Commonly, satellite and DEM based studies are being used in a first step of assessing areas of geologic interest. While in the past the analysis of satellite imagery (e.g. Landsat TM) and aerial photographs was carried out to characterize the regional geologic characteristics, particularly structure and lithology, geologists have increasingly ventured into a process-oriented approach. This entails assessing structures and geomorphic features with a concept that includes active tectonics or tectonic activity on time scales relevant to humans. In addition, these efforts involve analyzing and quantifying the processes acting at the surface by integrating different remote sensing and topographic data (e.g. SRTM-DEM, SSM/I, GPS, Landsat 7 ETM, Aster, Ikonos…). A combined structural and geomorphic study in the hyperarid Atacama desert demonstrates the use of satellite and digital elevation data for assessing geological structures formed by long-term (millions of years) feedback mechanisms between erosion and crustal bending (Zeilinger et al., 2005). The medium-term change of landscapes during hundred thousands to millions years in a more humid setting is shown in an example from southern Chile. Based on an analysis of rivers/watersheds combined with landscapes parameterization by using digital elevation models, the geomorphic evolution and change in drainage pattern in the coastal Cordillera can be quantified and put into the context of seismotectonic segmentation of a tectonically active region. This has far-reaching implications for earthquake rupture scenarios and hazard mitigation (K. Rehak, see poster on IMAF Workshop). Two examples illustrate short-term processes on decadal, centennial and millennial time scales: One study uses orogen scale precipitation gradients derived from remotely sensed passive microwave data (Bookhagen et al., 2005a). They demonstrate how debris flows were triggered as a response of slopes to abnormally strong rainfall in the interior parts of the Himalaya during intensified monsoons. The area of the orogen that receives high amounts of precipitation during intensified monsoons also constitutes numerous landslide deposits of up to 1km3 volume that were generated during intensified monsoon phase at about 27 and 9 ka (Bookhagen et al., 2005b). Another project in the Swiss Alps compared sets of aerial photographs recorded in different years. By calculating high resolution surfaces the mass transport in a landslide could be reconstructed (M. Schwab, Universität Bern). All these examples, although representing only a short and limited selection of projects using remote sense data in geology, have as a common approach the goal to quantify geological processes. With increasing data resolution and new sensors future projects will even enable us to recognize more patterns and / or structures indicative of geological processes in tectonically active areas. This is crucial for the analysis of natural hazards like earthquakes, tsunamis and landslides, as well as those hazards that are related to climatic variability. The integration of remotely sensed data at different spatial and temporal scales with field observations becomes increasingly important. Many of presently highly populated places and increasingly utilized regions are subject to significant environmental pressure and often constitute areas of concentrated economic value. Combined remote sensing and ground-truthing in these regions is particularly important as geologic, seismicity and hydrologic data may be limited here due to the recency of infrastructural development. Monitoring ongoing processes and evaluating the remotely sensed data in terms of recurrence of events will greatly enhance our ability to assess and mitigate natural hazards.

T1 - International Collaboration in Psychology is on the Rise
N2 - There has been a substantial increase in the percentage for publications with co-authors located in departments from different countries in 12 major journals of psychology. The results are evidence for a remarkable internationalization of psychological research, starting in the mid 1970s and increasing in rate at the beginning of the 1990s. This growth occurs against a constant number of articles with authors from the same country; it is not due to a concomitant increase in the number of co-authors per article. Thus, international collaboration in psychology is obviously on the rise.

T1 - Introduction of a thermo-sensitive non-polar species into polyelectrolyte multilayer capsules for drug delivery
T1 - Einbettung unpolarer, temperaturempfindlicher Substanzen in Polyelektrolytkapselsysteme zur Wirkstofffreisetzung
N2 - The layer-by-layer assembly (LBL) of polyelectrolytes has been extensively studied for the preparation of ultrathin films due to the versatility of the build-up process. The control of the permeability of these layers is particularly important as there are potential drug delivery applications. Multilayered polyelectrolyte microcapsules are also of great interest due to their possible use as microcontainers. This work will present two methods that can be used as employable drug delivery systems, both of which can encapsulate an active molecule and tune the release properties of the active species. Poly-(N-isopropyl acrylamide), (PNIPAM) is known to be a thermo-sensitive polymer that has a Lower Critical Solution Temperature (LCST) around 32oC; above this temperature PNIPAM is insoluble in water and collapses. It is also known that with the addition of salt, the LCST decreases. This work shows Differential Scanning Calorimetry (DSC) and Confocal Laser Scanning Microscopy (CLSM) evidence that the LCST of the PNIPAM can be tuned with salt type and concentration. Microcapsules were used to encapsulate this thermo-sensitive polymer, resulting in a reversible and tunable stimuli- responsive system. The encapsulation of the PNIPAM inside of the capsule was proven with Raman spectroscopy, DSC (bulk LCST measurements), AFM (thickness change), SEM (morphology change) and CLSM (in situ LCST measurement inside of the capsules). The exploitation of the capsules as a microcontainer is advantageous not only because of the protection the capsules give to the active molecules, but also because it facilitates easier transport. The second system investigated demonstrates the ability to reduce the permeability of polyelectrolyte multilayer films by the addition of charged wax particles. The incorporation of this hydrophobic coating leads to a reduced water sensitivity particularly after heating, which melts the wax, forming a barrier layer. This conclusion was proven with Neutron Reflectivity by showing the decreased presence of D2O in planar polyelectrolyte films after annealing creating a barrier layer. The permeability of capsules could also be decreased by the addition of a wax layer. This was proved by the increase in recovery time measured by Florescence Recovery After Photobleaching, (FRAP) measurements. In general two advanced methods, potentially suitable for drug delivery systems, have been proposed. In both cases, if biocompatible elements are used to fabricate the capsule wall, these systems provide a stable method of encapsulating active molecules. Stable encapsulation coupled with the ability to tune the wall thickness gives the ability to control the release profile of the molecule of interest.
N2 - Verkapselung ist ein vielseitiges Werkzeug, das zum Schutz und zum Transport von Molekülen ebenso eingesetzt werden kann, wie zur Verbindung von Reaktionspartnern in einem gemeinsamen, von der Umgebung abgeschirmten Raum. Es basiert auf einem einfachen Vorbild der Natur. Pflanzen schützen ihren Samen zum Beispiel durch eine harte, nahezu undurchdringbare Schale (Nüsse) oder durch eine selektiv durchlässige Hülle, wie bei Weizen, der sobald er feucht wird zu keimen beginnt. Die Natur setzt durch den Einsatz des Hülle-Kern Prinzips sehr effizient die Kontrolle über Durchlässigkeit und Anpassung an bestimmte Aufgaben um. Wird das Hülle-Kern-Prinzip zum Schutz oder Transport von Molekülen eingesetzt, so sind die zu verwendenden Kapseln nur wenige Mikrometer groß. Sie werden dann als Mikrokapseln bezeichnet. Zur Erzeugung dieser Mikrokapseln werden verschiedene Methoden verwendet. Der heute übliche Weg geht von einer ca. 5-10 Mikrometer großen Kugel (Kern) aus, die mit einer stabilen und an die gewünschten Eigenschaften angepassten Schicht von wenigen Nanometern versehen wird. Im Anschluss wird der Kern herausgelöst und eine hohle, stabile Kapsel erhalten. Schichten von wenigen Nanometern Dicke können aus Polyelektrolyten durch das Layer-by-Layer-Verfahren (LbL) hergestellt werden. Dieses Verfahren eignet sich auf Grund seiner vielen Anpassungsmöglichkeiten besonders zum Aufbau der Schichten für Mikrokapseln, da sich die Eigenschaften der Beschichtung bereits beim Aufbau der Schicht auf die Bedürfnisse maßschneidern lassen. Diese Arbeit befasst sich mit der Erzeugung von Mikrokapseln, deren Eigenschaften temperaturabhängig sind. Dies wurde auf zwei Wegen erreicht. Zum einen wurden Kapseln aus Polyelektrolyten und Wachs aufgebaut. Bei Temperaturerhöhung schmilzt das Wachs und versiegelt die Kapsel. Zum anderen werden Kapseln mit einem Wärme empfindlichen Polymer gefüllt. Bei Temperaturerhöhung kollabiert das Polymergerüst. Der enthaltene Wirkstoff wird freigesetzt.

N2 - American occupying forces made the promotion of Jewish-Christian dialogue part of their plans for postwar German reconstruction. They sought to export American models of Jewish-Christian cooperation to Germany, while simultaneously validating and valorizing claims about the connection between democracy and tri-faith religious pluralism in the United States. The small size of the Jewish population in Germany meant that Jews did not set the terms of these discussions, and evidence shows that both German and American Jews expressed skepticism about participating in dialogue in the years immediately following the Holocaust. But opting out would have meant that discussions in Germany about the Judeo-Christian tradition that the American government advanced as the centerpiece of postwar democratic reconstruction would take place without a Jewish contribution. American Jewish leaders, present in Germany and in the US, therefore decided to opt in, not because they supported the project, but because it seemed far riskier to be left out.

T2 - State, Law, and Politics — Research and Discussion Papers
N2 - Under Brazil's ex-president Bolsonaro, deforestation of the Amazon increased dramatically. An Austrian NGO filed a complaint to the Prosecutor of the International Criminal Court (ICC) against Bolsonaro in October 2021, accusing him of crimes against humanity against the backdrop of his involvement in environmental destruction. This paper deals with the question of whether this initi-ative constitutes a promising means of juridification to mitigate conflicts revolving around mass deforestation in Brazil. It thematizes attempts to juridify environmental destruction in international criminal law and examines the Climate Fund Case at the Brazilian Supreme Court. Finally, emerging problems and arguments in favour of starting preliminary examinations at the ICC against Bolsonaro are illuminated. This paper provides arguments as to why the initiative might be a promising undertaking, even though it is unlikely that Bolsonaro will be arrested.

Eine österreichi-sche NGO reichte im Oktober 2021 beim Anklä-ger des Internationalen Strafgerichtshofs (IStGH) eine Beschwerde gegen Bolsonaro ein, die seine Abholzungspolitik als Verbrechen gegen die Menschlichkeit einstuft. Der Beitrag behandelt die Frage, ob die Initiative ein vielversprechen-des Mittel der Verrechtlichung darstellt, um Kon-flikte rund um die Massenabholzung des Amazo-nas zu entschärfen. Dafür werden Versuche be-leuchtet, Umweltzerstörung im internationalen Strafrecht zu verrechtlichen. Zudem wird der Klimafonds-Fall vor dem Obersten Gerichtshof Brasiliens vorgestellt. Abschließend werden Probleme und Argumente für die Einleitung von Voruntersuchungen gegen Bolsonaro vor dem IStGH diskutiert. Der Beitrag liefert Argumente, weshalb die Initiative erfolgreich sein könnte, obgleich es unwahrscheinlich ist, dass Bolsonaro verhaftet wird.

T1 - Kato: a plagiarism-detection tool for answer-set programs
N2 - We present the tool Kato which is, to the best of our knowledge, the first tool for plagiarism detection that is directly tailored for answer-set programming (ASP). Kato aims at finding similarities between (segments of) logic programs to help detecting cases of plagiarism. Currently, the tool is realised for DLV programs but it is designed to handle various logic-programming syntax versions. We review basic features and the underlying methodology of the tool.

T1 - Large-scale wind structure due to magnetic fields
N2 - Magnetic fields influence the dynamics of hot-star winds and create large scale structure. Based on numerical magnetohydrodynamic (MHD) simulations, we model the wind of θ¹ Ori C, and then use the SEI method to compute synthetic line profiles for a range of viewing angles as function of rotational phase. The resulting dynamic spectrum for a moderately strong line shows a distinct modulation, but with a phase that seems at odds with available observations.

T1 - Leadership Training in Malaysia
BT - Impact and Implications
JF - Potsdamer Beiträge zur Hochschulforschung
N2 - The higher education structure in Malaysia has experienced significant changes since the implementation of the Private Higher Educational Institutions Act of 1996. The unprecedented expansion of the higher education sector and the increasing autonomy conferred to universities have created a huge demand for competent university leadership that supports the development of higher education in Malaysia. This article discusses the very first national multiplication training in Malaysia in 2014 and analyses such out-comes as the identification of good practices for future initiatives and applications in university leadership training.

T1 - Lessons Drawn from Evaluation and Implementation of the Malaysian Chapter of the International Deans’ Course
JF - Potsdamer Beiträge zur Hochschulforschung
N2 - Deans at Institutions of Higher Education are seldom recipients of effective or specific professional management training, institutional mentorship, and coaching despite an increasing demand on them to play a more dynamic leadership role in the face of ever-changing local and global challenges. To address this deficiency, the inaugural Malaysian Chapter of the International Deans’ Course (MyIDC) was held in three parts over 2019 and 2020. In this paper, findings related to feedback on the programme are presented and discussed. Responses from the participants from two sets of surveys, and written feedback provided by two IDC international trainers involved in MyIDC were analysed. These reveal potential areas of improvement for the forthcoming MyIDC programme, such as in terms of planning and organisation, duration, content, and delivery. The article explores the lessons learnt from the MyIDC 2019/2020 training programme and discusses the improvements that can be made arising from the feedback received.
