Background:
Deception can distort psychological tests on socially sensitive topics. Understanding the cerebral
processes that are involved in such faking can be useful in detection and prevention of deception. Previous research
shows that faking a brief implicit association test (BIAT ) evokes a characteristic ERP response. It is not yet known
whether temporarily available self-control resources moderate this response. We randomly assigned 22 participants
(15 females, 24.23
±
2.91
years old) to a counterbalanced repeated-measurements design. Participants first com-
pleted a Brief-IAT (BIAT ) on doping attitudes as a baseline measure and were then instructed to fake a negative dop
-
ing attitude both when self-control resources were depleted and non-depleted. Cerebral activity during BIAT perfor
-
mance was assessed using high-density EEG.
Results:
Compared to the baseline BIAT, event-related potentials showed a first interaction at the parietal P1,
while significant post hoc differences were found only at the later occurring late positive potential. Here, signifi-
cantly decreased amplitudes were recorded for ‘normal’ faking, but not in the depletion condition. In source space,
enhanced activity was found for ‘normal’ faking in the bilateral temporoparietal junction. Behaviorally, participants
were successful in faking the BIAT successfully in both conditions.
Conclusions:
Results indicate that temporarily available self-control resources do not affect overt faking success on
a BIAT. However, differences were found on an electrophysiological level. This indicates that while on a phenotypical
level self-control resources play a negligible role in deliberate test faking the underlying cerebral processes are markedly different.
Proteins are amphiphilic and adsorb at liquid interfaces. Therefore, they can be efficient stabilizers of foams and emulsions. β-lactoglobulin (BLG) is one of the most widely studied proteins due to its major industrial applications, in particular in food technology.
In the present work, the influence of different bulk concentration, solution pH and ionic strength on the dynamic and equilibrium pressures of BLG adsorbed layers at the solution/tetradecane (W/TD) interface has been investigated. Dynamic interfacial pressure (Π) and interfacial dilational elastic modulus (E’) of BLG solutions for various concentrations at three different pH values of 3, 5 and 7 at a fixed ionic strength of 10 mM and for a selected fixed concentration at three different ionic strengths of 1 mM, 10 mM and 100 mM are measured by Profile Analysis Tensiometer PAT-1 (SINTERFACE Technologies, Germany). A quantitative data analysis requires additional consideration of depletion due to BLG adsorption at the interface at low protein bulk concentrations. This fact makes experiments more efficient when oil drops are studied in the aqueous protein solutions rather than solution drops formed in oil. On the basis of obtained experimental data, concentration dependencies and the effect of solution pH on the protein surface activity was qualitatively analysed. In the presence of 10 mM buffer, we observed that generally the adsorbed amount is increasing with increasing BLG bulk concentration for all three pH values. The adsorption kinetics at pH 5 result in the highest Π values at any time of adsorption while it exhibits a less active behaviour at pH 3.
Since the experimental data have not been in a good agreement with the classical diffusion controlled model due to the conformational changes which occur when the protein molecules get in contact with the hydrophobic oil phase in order to adapt to the interfacial environment, a new theoretical model is proposed here. The adsorption kinetics data were analysed with the newly proposed model, which is the classical diffusion model but modified by assuming an additional change in the surface activity of BLG molecules when adsorbing at the interface. This effect can be expressed through the adsorption activity constant in the corresponding equation of state. The dilational visco-elasticity of the BLG adsorbed interfacial layers is determined from measured dynamic interfacial tensions during sinusoidal drop area variations. The interfacial tension responses to these harmonic drop oscillations are interpreted with the same thermodynamic model which is used for the corresponding adsorption isotherm.
At a selected BLG concentration of 2×10-6 mol/l, the influence of the ionic strength using different buffer concentration of 1, 10 and 100 mM on the interfacial pressure was studied. It is affected weakly at pH 5, whereas it has a strong impact by increasing buffer concentration at pH 3 and 7. In conclusion, the structure formation of BLG adsorbed layer in the early stage of adsorption at the W/TD interface is similar to those of the solution/air (W/A) surface. However, the equation of state at the W/TD interface provides an adsorption activity constant which is almost two orders of magnitude higher than that for the solution/air surface.
At the end of this work, a new experimental tool called Drop and Bubble Micro Manipulator DBMM (SINTERFACE Technologies, Germany) has been introduced to study the stability of protein covered bubbles against coalescence. Among the available protocols the lifetime between the moment of contact and coalescence of two contacting bubble is determined for different BLG concentrations. The adsorbed amount of BLG is determined as a function of time and concentration and correlates with the observed coalescence behaviour of the contacting bubbles.
Gut bacteria exert beneficial and harmful effects in metabolic diseases as deduced from the comparison of germfree and conventional mice and from fecal transplantation studies. Compositional microbial changes in diseased subjects have been linked to adiposity, type 2 diabetes and dyslipidemia. Promotion of an increased expression of intestinal nutrient transporters or a modified lipid and bile acid metabolism by the intestinal microbiota could result in an increased nutrient absorption by the host. The degradation of dietary fiber and the subsequent fermentation of monosaccharides to short-chain fatty acids (SCFA) is one of the most controversially discussed mechanisms of how gut bacteria impact host physiology. Fibers reduce the energy density of the diet, and the resulting SCFA promote intestinal gluconeogenesis, incretin formation and subsequently satiety. However, SCFA also deliver energy to the host and support liponeogenesis. Thus far, there is little knowledge on bacterial species that promote or prevent metabolic disease. Clostridium ramosum and Enterococcus cloacae were demonstrated to promote obesity in gnotobiotic mouse models, whereas bifidobacteria and Akkermansia muciniphila were associated with favorable phenotypes in conventional mice, especially when oligofructose was fed. How diet modulates the gut microbiota towards a beneficial or harmful composition needs further research. Gnotobiotic animals are a valuable tool to elucidate mechanisms underlying diet-host-microbe interactions.
Recently, due to an increasing demand on functionality and flexibility, beforehand isolated systems have become interconnected to gain powerful adaptive Systems of Systems (SoS) solutions with an overall robust, flexible and emergent behavior. The adaptive SoS comprises a variety of different system types ranging from small embedded to adaptive cyber-physical systems. On the one hand, each system is independent, follows a local strategy and optimizes its behavior to reach its goals. On the other hand, systems must cooperate with each other to enrich the overall functionality to jointly perform on the SoS level reaching global goals, which cannot be satisfied by one system alone. Due to difficulties of local and global behavior optimizations conflicts may arise between systems that have to be solved by the adaptive SoS.
This thesis proposes a modeling language that facilitates the description of an adaptive SoS by considering the adaptation capabilities in form of feedback loops as first class entities. Moreover, this thesis adopts the Models@runtime approach to integrate the available knowledge in the systems as runtime models into the modeled adaptation logic. Furthermore, the modeling language focuses on the description of system interactions within the adaptive SoS to reason about individual system functionality and how it emerges via collaborations to an overall joint SoS behavior. Therefore, the modeling language approach enables the specification of local adaptive system behavior, the integration of knowledge in form of runtime models and the joint interactions via collaboration to place the available adaptive behavior in an overall layered, adaptive SoS architecture.
Beside the modeling language, this thesis proposes analysis rules to investigate the modeled adaptive SoS, which enables the detection of architectural patterns as well as design flaws and pinpoints to possible system threats. Moreover, a simulation framework is presented, which allows the direct execution of the modeled SoS architecture. Therefore, the analysis rules and the simulation framework can be used to verify the interplay between systems as well as the modeled adaptation effects within the SoS. This thesis realizes the proposed concepts of the modeling language by mapping them to a state of the art standard from the automotive domain and thus, showing their applicability to actual systems. Finally, the modeling language approach is evaluated by remodeling up to date research scenarios from different domains, which demonstrates that the modeling language concepts are powerful enough to cope with a broad range of existing research problems.
In this study, we investigated the scale sizes of equatorial plasma irregularities (EPIs) using measurements from the Swarm satellites during its early mission and final constellation phases. We found that with longitudinal separation between Swarm satellites larger than 0.4°, no significant correlation was found any more. This result suggests that EPI structures include plasma density scale sizes less than 44 km in the zonal direction. During the Swarm earlier mission phase, clearly better EPI correlations are obtained in the northern hemisphere, implying more fragmented irregularities in the southern hemisphere where the ambient magnetic field is low. The previously reported inverted-C shell structure of EPIs is generally confirmed by the Swarm observations in the northern hemisphere, but with various tilt angles. From the Swarm spacecrafts with zonal separations of about 150 km, we conclude that larger zonal scale sizes of irregularities exist during the early evening hours (around 1900 LT).
The eukaryotic-specific Isd11 is a complex- orphan protein with ability to bind the prokaryotic IscS
(2016)
The eukaryotic protein Isd11 is a chaperone that binds and stabilizes the central component of the essential metabolic pathway responsible for formation of iron-sulfur clusters in mitochondria, the desulfurase Nfs1. Little is known about the exact role of Isd11. Here, we show that human Isd11 (ISD11) is a helical protein which exists in solution as an equilibrium between monomer, dimeric and tetrameric species when in the absence of human Nfs1 (NFS1). We also show that, surprisingly, recombinant ISD11 expressed in E. coli co-purifies with the bacterial orthologue of NFS1, IscS. Binding is weak but specific suggesting that, despite the absence of Isd11 sequences in bacteria, there is enough conservation between the two desulfurases to retain a similar mode of interaction. This knowledge may inform us on the conservation of the mode of binding of Isd11 to the desulfurase. We used evolutionary evidence to suggest Isd11 residues involved in the interaction.
Background: The efficiency of multiplex editing in plants by the RNA-guided Cas9 system is limited by efficient introduction of its components into the genome and by their activity. The possibility of introducing large fragment deletions by RNA-guided Cas9 tool provides the potential to study the function of any DNA region of interest in its
‘endogenous’ environment.
Results: Here, an RNA-guided Cas9 system was optimized to enable efficient multiplex editing in Arabidopsis thaliana. We demonstrate the flexibility of our system for knockout of multiple genes, and to generate heritable largefragment deletions in the genome. As a proof of concept, the function of part of the second intron of the flower development gene AGAMOUS in Arabidopsis was studied by generating a Cas9-free mutant plant line in which part of this intron was removed from the genome. Further analysis revealed that deletion of this intron fragment results 40 % decrease of AGAMOUS gene expression without changing the splicing of the gene which indicates that this regulatory region functions as an activator of AGAMOUS gene expression.
Conclusions: Our modified RNA-guided Cas9 system offers a versatile tool for the functional dissection of coding and non-coding DNA sequences in plants.
We present results on ultrafast gas electron diffraction (UGED) experiments with femtosecond resolution using the MeV electron gun at SLAC National Accelerator Laboratory. UGED is a promising method to investigate molecular dynamics in the gas phase because electron pulses can probe the structure with a high spatial resolution. Until recently, however, it was not possible for UGED to reach the relevant timescale for the motion of the nuclei during a molecular reaction. Using MeV electron pulses has allowed us to overcome the main challenges in reaching femtosecond resolution, namely delivering short electron pulses on a gas target, overcoming the effect of velocity mismatch between pump laser pulses and the probe electron pulses, and maintaining a low timing jitter. At electron kinetic energies above 3 MeV, the velocity mismatch between laser and electron pulses becomes negligible. The relativistic electrons are also less susceptible to temporal broadening due to the Coulomb force. One of the challenges of diffraction with relativistic electrons is that the small de Broglie wavelength results in very small diffraction angles. In this paper we describe the new setup and its characterization, including capturing static diffraction patterns of molecules in the gas phase, finding time-zero with sub-picosecond accuracy and first time-resolved diffraction experiments. The new device can achieve a temporal resolution of 100 fs root-mean-square, and sub-angstrom spatial resolution. The collimation of the beam is sufficient to measure the diffraction pattern, and the transverse coherence is on the order of 2 nm. Currently, the temporal resolution is limited both by the pulse duration of the electron pulse on target and by the timing jitter, while the spatial resolution is limited by the average electron beam current and the signal-to-noise ratio of the detection system. We also discuss plans for improving both the temporal resolution and the spatial resolution.
Metal-containing ionic liquids (ILs) are of interest for a variety of technical applications, e.g., particle synthesis and materials with magnetic or thermochromic properties. In this paper we report the synthesis of, and two structures for, some new tetrabromidocuprates(II) with several “onium” cations in comparison to the results of electron paramagnetic resonance (EPR) spectroscopic analyses. The sterically demanding cations were used to separate the paramagnetic Cu(II) ions for EPR measurements. The EPR hyperfine structure in the spectra of these new compounds is not resolved, due to the line broadening resulting from magnetic exchange between the still-incomplete separated paramagnetic Cu(II) centres. For the majority of compounds, the principal g values (g|| and gK) of the tensors could be determined and information on the structural changes in the [CuBr4]2- anions can be obtained. The complexes have high potential, e.g., as ionic liquids, as precursors for the synthesis of copper bromide particles, as catalytically active or paramagnetic ionic liquids.
Venomous snakes often display extensive variation in venom composition both between and within species. However, the mechanisms underlying the distribution of different toxins and venom types among populations and taxa remain insufficiently known. Rattlesnakes (Crotalus, Sistrurus) display extreme inter-and intraspecific variation in venom composition, centered particularly on the presence or absence of presynaptically neurotoxic phospholipases A2 such as Mojave toxin (MTX). Interspecific hybridization has been invoked as a mechanism to explain the distribution of these toxins across rattlesnakes, with the implicit assumption that they are adaptively advantageous. Here, we test the potential of adaptive hybridization as a mechanism for venom evolution by assessing the distribution of genes encoding the acidic and basic subunits of Mojave toxin across a hybrid zone between MTX-positive Crotalus scutulatus and MTX-negative C. viridis in southwestern New Mexico, USA. Analyses of morphology, mitochondrial and single copy-nuclear genes document extensive admixture within a narrow hybrid zone. The genes encoding the two MTX subunits are strictly linked, and found in most hybrids and backcrossed individuals, but not in C. viridis away from the hybrid zone. Presence of the genes is invariably associated with presence of the corresponding toxin in the venom. We conclude that introgression of highly lethal neurotoxins through hybridization is not necessarily favored by natural selection in rattlesnakes, and that even extensive hybridization may not lead to introgression of these genes into another species.

The all-female Amazon molly (Poecilia formosa) originated from a single hybridization of two bisexual ancestors, Atlantic molly (Poecilia mexicana) and sailfin molly (Poecilia latipinna). As a gynogenetic species, the Amazon molly needs to copulate with a heterospecific male, but the genetic information of the sperm-donor does not contribute to the next generation, as the sperm only acts as the trigger for the diploid eggs’ embryogenesis. Here, we study the sequence evolution and gene expression of the duplicated genes coding for androgen receptors (ars) and other pathway-related genes, i.e., the estrogen receptors (ers) and cytochrome P450, family19, subfamily A, aromatase genes (cyp19as), in the Amazon molly, in comparison to its bisexual ancestors. Mollies possess–as most other teleost fish—two copies of the ar, er, and cyp19a genes, i.e., arα/arβ, erα/erβ1, and cyp19a1 (also referred as cyp19a1a)/cyp19a2 (also referred to as cyp19a1b), respectively. Non-synonymous single nucleotide polymorphisms (SNPs) among the ancestral bisexual species were generally predicted not to alter protein function. Some derived substitutions in the P. mexicana and one in P. formosa are predicted to impact protein function. We also describe the gene expression pattern of the ars and pathway-related genes in various tissues (i.e., brain, gill, and ovary) and provide SNP markers for allele specific expression research. As a general tendency, the levels of gene expression were lowest in gill and highest in ovarian tissues, while expression levels in the brain were intermediate in most cases. Expression levels in P. formosa were conserved where expression did not differ between the two bisexual ancestors. In those cases where gene expression levels significantly differed between the bisexual species, P. formosa expression was always comparable to the higher expression level among the two ancestors. Interestingly, erβ1 was expressed neither in brain nor in gill in the analyzed three molly species, which implies a more important role of erα in the estradiol synthesis pathway in these tissues. Furthermore, our data suggest that interactions of steroid-signaling pathway genes differ across tissues, in particular the interactions of ars and cyp19as.
The knowledge of the contemporary in situ stress state is a key issue for safe and sustainable subsurface engineering. However, information on the orientation and magnitudes of the stress state is limited and often not available for the areas of interest. Therefore 3-D geomechanical-numerical modelling is used to estimate the in situ stress state and the distance of faults from failure for application in subsurface engineering. The main challenge in this approach is to bridge the gap in scale between the widely scattered data used for calibration of the model and the high resolution in the target area required for the application. We present a multi-stage 3-D geomechanical-numerical approach which provides a state-of-the-art model of the stress field for a reservoir-scale area from widely scattered data records. Therefore, we first use a large-scale regional model which is calibrated by available stress data and provides the full 3-D stress tensor at discrete points in the entire model volume. The modelled stress state is used subsequently for the calibration of a smaller-scale model located within the large-scale model in an area without any observed stress data records. We exemplify this approach with two-stages for the area around Munich in the German Molasse Basin. As an example of application, we estimate the scalar values for slip tendency and fracture potential from the model results as measures for the criticality of fault reactivation in the reservoir-scale model. The modelling results show that variations due to uncertainties in the input data are mainly introduced by the uncertain material properties and missing S-Hmax magnitude estimates needed for a more reliable model calibration. This leads to the conclusion that at this stage the model's reliability depends only on the amount and quality of available stress information rather than on the modelling technique itself or on local details of the model geometry. Any improvements in modelling and increases in model reliability can only be achieved using more high-quality data for calibration.
Die vorliegende Untersuchung verfolgt das Ziel, kulturelle und religiöse Aspekte der Erneuerung jüdischen Lebens in Berlin seit 1989 zu erforschen. Die Entwicklungen der jüdischen Gemeinschaft in der Hauptstadt seit dem Fall der Mauer und dem Zusammenbruch der Sowjetunion führen zur Wiederannäherung eines Teils der jüdischen Bevölkerung in Deutschland an die eigene Kultur, Religion und Geschichte. Dabei kommt die Pluralität der kulturellen, literarischen und religiösen Ausdrucksformen der jüdischen Identitäten zum Vorschein. Die Arbeit verdeutlicht diese in Berlin nach 1989 einsetzende kulturelle und religiöse „Renaissance“. Vier wichtige Punkte kennzeichnen das jüdische Leben in Berlin nach 1989. Erstens gewinnt Deutschland seit der Wiedervereinigung eine neue Rolle als mögliches Einwanderungsland für Juden. Vor allem mit der massiven jüdischen Einwanderung aus den Staaten der ehemaligen Sowjetunion seit den 1990er Jahren wird Deutschland allmählich als wichtiges Zentrum in der europäischen Diaspora anerkannt. Zweitens bleibt zwar die Shoah tief verankert im Gedächtnis der jüdischen Gemeinschaft; die meisten Kinder oder Enkelkinder von Überlebenden der Shoah weigern sich jedoch, ihre jüdische Identität exklusiv durch die Shoah zu definieren. Sie gründen zur Wiederentdeckung und Forderung ihres kulturellen, religiösen und historischen Erbes jüdische Gruppen und Einrichtungen in Berlin, die in den meisten Fällen alternativ zur Jüdischen Gemeinde entstehen: Künstlergruppen, jüdische Kulturvereine, Konferenzen und Podiumsdiskussionen, religiöse Kongregationen und Lernhäuser. Damit – und dies ist der dritte Punkt – verliert zwar die offizielle Jüdische Gemeinde an Bedeutung als einzige Vertreterin der jüdischen Gemeinschaft Berlins; diese kulturelle und religiöse „Renaissance“ außerhalb der offiziellen Strukturen der Gemeinde bedeutet aber auch eine wachsende Pluralität und Diversifizierung der jüdischen Gemeinschaft in Berlin. Viertens spielt Berlin die Hauptrolle in diesem Prozess. Heute werden viele ehemalige jüdische Orte neu belebt: Synagogen werden wiederentdeckt und renoviert, Denk- und Mahnmale gebaut, Stadtführungen auf der Spur des „jüdischen Berlins“ organisiert, Rabbinerseminare neu gegründet. Die Topographie Berlins bildet auch eine Inspirationsquelle für jüdische (und nichtjüdische) Schriftsteller und Künstler. Die Analyse dieser nach 1989 entstandenen religiösen Initiativen, literarischen Werke und kulturellen Produktionen dient dazu, Aspekte der kulturellen und religiösen „Renaissance“ in Berlin näher zu verdeutlichen.
The concept of three journeys as a way to denote spiritual development was introduced
by Dhu al-Nun, one of the founding fathers of Islamic mysticism. The use of this
concept was later refined by combining it with the Sufi technique of adding different
prepositions to a certain term, in order to differentiate between spiritual stages. By
using the words journey (Safar) and God (Allah) and inserting a preposition before the
word God, Sufi writers could map the different roads to God or the stations (Maqamat) on this road. Ibn al-'Arabi, in the beginning of the thirteenth century, speaks of three
different ways: from God, toward God and in God. Tanchum ha-Yerushalmi, the Judeo
Arabic biblical commentator from the end of this century, speaks of the three journeys
as three stations of one continuous way. A nearly identical description we can find in
the writing of the Muslim scholar Ibn Qayyim al-Jawziyya, a generation later. Later in
the fourteenth century, in the writing of the Sufi writer al-Qashani, the three travels
become four, although the scheme of three prepositions is preserved. Near the end of
the fourteenth century, in the writings of R. David ha-Nagid, we find only two journeys:
to God and in God. All this tells us that Judeo Arabic literature can help us map
with greater precision the historical development of Sufi ideas.

Unlike for other retroviruses, only a few host cell factors that aid the replication of foamy viruses (FVs) via interaction with viral structural components are known. Using a yeast-two-hybrid (Y2H) screen with prototype FV (PFV) Gag protein as bait we identified human polo-like kinase 2 (hPLK2), a member of cell cycle regulatory kinases, as a new interactor of PFV capsids. Further Y2H studies confirmed interaction of PFV Gag with several PLKs of both human and rat origin. A consensus Ser-Thr/Ser-Pro (S-T/S-P) motif in Gag, which is conserved among primate FVs and phosphorylated in PFV virions, was essential for recognition by PLKs. In the case of rat PLK2, functional kinase and polo-box domains were required for interaction with PFV Gag. Fluorescently-tagged PFV Gag, through its chromatin tethering function, selectively relocalized ectopically expressed eGFP-tagged PLK proteins to mitotic chromosomes in a Gag STP motif-dependent manner, confirming a specific and dominant nature of the Gag-PLK interaction in mammalian cells. The functional relevance of the Gag-PLK interaction was examined in the context of replication-competent FVs and single-round PFV vectors. Although STP motif mutated viruses displayed wild type (wt) particle release, RNA packaging and intra-particle reverse transcription, their replication capacity was decreased 3-fold in single-cycle infections, and up to 20-fold in spreading infections over an extended time period. Strikingly similar defects were observed when cells infected with single-round wt Gag PFV vectors were treated with a pan PLK inhibitor. Analysis of entry kinetics of the mutant viruses indicated a post-fusion defect resulting in delayed and reduced integration, which was accompanied with an enhanced preference to integrate into heterochromatin. We conclude that interaction between PFV Gag and cellular PLK proteins is important for early replication steps of PFV within host cells.
Background:
Plant phenotypic data shrouds a wealth of information which, when accurately analysed and linked
to other data types, brings to light the knowledge about the mechanisms of life. As phenotyping is a field of research
comprising manifold, diverse and time
‑consuming experiments, the findings can be fostered by reusing and combin‑
ing existing datasets. Their correct interpretation, and thus replicability, comparability and interoperability, is possible
provided that the collected observations are equipped with an adequate set of metadata. So far there have been no
common standards governing phenotypic data description, which hampered data exchange and reuse.
Results:
In this paper we propose the guidelines for proper handling of the information about plant phenotyping
experiments, in terms of both the recommended content of the description and its formatting. We provide a docu‑
ment called “Minimum Information About a Plant Phenotyping Experiment”, which specifies what information about
each experiment should be given, and a Phenotyping Configuration for the ISA
‑Tab format, which allows to practically
organise this information within a dataset. We provide examples of ISA
‑Tab
‑formatted phenotypic data, and a general
description of a few systems where the recommendations have been implemented.
Conclusions:
Acceptance of the rules described in this paper by the plant phenotyping community will help to
achieve findable, accessible, interoperable and reusable data.
Ökonomen wie Wirtschaftspolitiker berufen sich auf die Neutralitätstheorie des Geldes, wenn sie eine Entpolitisierung der Geldpolitik fordern. Sowohl die Theorie der Geldneutralität als auch das Paradigma der Entpolitisierung der Geldpolitik sind jedoch problematisch. Die politökonomischen Entwicklungen nach der globalen Finanz- und Wirtschaftskrise 2007/2008 und die jüngsten Kontroversen über die Rolle und Bedeutung von Geld haben dies deutlich vor Augen geführt. Die vorliegende Arbeit diskutiert zunächst die konzeptionellen Grundlagen und theoretischen Modelle der Geldneutralität. Anschließend werden die zentralen theoretischen Annahmen und Aussagen der Neutralitätstheorie aus einer kritischen heterodoxen Perspektive hinterfragt. Es wird argumentiert, dass Geld eine nicht-neutrale Produktionskraft ist, die weder ökonomisch noch sozial neutral ist. Die Bedingungen, unter denen Geld verfügbar ist und zirkuliert, sind richtungsweisend für die ökonomische Entwicklung. Daher kann es auch kein neutrales Geld oder gar eine apolitische Geldpolitik geben.
Die vorliegende Arbeit untersucht die Politik der Zentralbankunabhängigkeit (ZBU) am Beispiel der Türkei. Im Mittelpunkt der Arbeit stehen theoretische und empirische Fragen und Probleme, die sich im Zusammenhang mit der ZBU stellen und anhand der türkischen Geldpolitik diskutiert werden. Ein zentrales Ziel der Arbeit besteht darin, zu untersuchen, ob und inwiefern die türkische Zentralbank nach Erlangung der de jure institutionellen Unabhängigkeit tatsächlich als unabhängig und entpolitisiert eingestuft werden kann. Um diese Forschungsfrage zu beantworten, werden die institutionellen Bedingungen, die Ziele und die Regeln, nach denen sich die türkische Geldpolitik richtet, geklärt. Anschließend wird empirisch überprüft, ob die geldpolitische Praxis der CBRT sich an dem offiziell vorgegebenen Regelwerk orientiert. Die Hauptthese dieser Arbeit lautet, dass die formelle Unabhängigkeit der CBRT und die regelorientierte Geldpolitik nicht mit einer Entpolitisierung der Geldpolitik in der Türkei gleichzusetzen ist. Als Alternative schlägt die vorliegende Studie vor, den institutionellen Status der CBRT als einen der relativen Autonomie zu untersuchen. Auch eine de jure unabhängige Zentralbank kann sich nicht von politischen Eingriffen abkoppeln, wie das Fallbeispiel Türkei zeigen wird.

Vom 18. bis 20. September 2014 versammelten sich an der Universität Potsdam kultur- und filmwissenschaftlich arbeitende Wissenschaftler zu einem Andrej Tarkovskij gewidmeten Symposium, dem ersten internationalen. Die 25 Teilnehmer kamen nämlich aus neun Ländern. Dadurch, dass nicht wenige auch eine – wie man heute sagt – „Migrationsbiographie“ haben, potenzierte sich die durch die jeweils unterschiedliche Herkunft bedingte Multiperspektivik, zu der jedoch der Modus der Wissenschaftlichkeit ein deutlich relativierendes Korrektiv bildet. Der vorliegende Band enthält im Wesentlichen die dort vorgestellten Beiträge, aber auch die der Fachleute, die nicht persönlich hatten nach Potsdam kommen können.

Биографические мотивы условно можно разделить на два вида:
1. Отдельные небольшие эпизоды или впечатления, запомнившие-
ся Тарковскому, которые заняли свое точное место в его сценариях и
фильмах. Режиссер А. Гордон условно назвал этот прием Тарковского
«теорией пазлов». Такие элементы встречаются почти во всех фильмах
Андрея Тарковского.
2. Расширенное включение в фильмы автобиографии, естественно, не
во всей полноте. К таким фильмам относятся Зеркало (1974) и Offret
(«Жертвоприношение» – 1986).

Der Jüdische Friedhof in Potsdam ist der einzige authentische Gedächtnisort, der vom Lebenszyklus der jüdischen Bevölkerung in der ehemaligen preußischen Residenz- und Garnisonstadt zeugt. Er ist zudem Ausdruck des unterschiedlichen Umgangs der Nachgeborenen mit ihrem Kulturgut. Außerdem ist dieser Jüdische Friedhof zurzeit als einziger in Deutschland durch die UNESCO als Welterbe anerkannt.
Da die jüdische Geschichte Potsdams bislang nur wenig bekannt ist, entstand ein durch die Stiftung „Erinnerung, Verantwortung und Zukunft“ gefördertes Projekt, in dem sich Schüler*innen des Potsdamer Humboldt-Gymnasiums im Rahmen eines Seminarkurses mit dem jüdischen Erbe ihrer Stadt intensiv auseinandersetzten. Neben einer Annäherung an das Thema über verschiedene, den Friedhof betreffende Sachthemen beschäftigten sich die Jugendlichen mit einzelnen jüdischen Potsdamern, ihren Familienschicksalen und Lebenskonzepten. Ergänzend wurden Aspekte des religiösen Verständnisses von Tod und Trauer im Judentum vorgestellt.
Die Ergebnisse all dieser Ausarbeitungen sind im vorliegenden Lehrmaterial vereinigt und dienen als Anregung für Lehrende und Lernende, die jüdische Geschichte ihrer jeweiligen Heimatorte zu thematisieren.

2014 fand der Potsdamer Lateintag zum 10. Mal statt. Das Jubiläum war ein angemessener Anlass, unser neues Projekt vorzustellen. Die Robert Bosch-Stiftung fördert wieder für drei Jahre die Zusammenarbeit der Klassischen Philologie der Universität Potsdam mit Schulen aus Brandenburg. Der Titel lautet: www.BrAnD2. Wille. Würde. Wissen. Zweites Brandenburger Antike-Denkwerk. Zur Auftaktveranstaltung zum Thema „Wille“ erschienen wieder über 500 Teilnehmerinnen und Teilnehmer. Der Band versammelt einen Projektbericht, die Vorträge von Frau Prof. Dr. Christiane Kunst und Herrn Prof. Dr. Christoph Horn sowie eine Auswahl an Materialen der betreuenden Studierenden.
Der Jüdische Friedhof in Potsdam ist der einzige authentische Gedächtnisort, der vom Lebenszyklus der jüdischen Bevölkerung in der ehemaligen preußischen Residenz- und Garnisonstadt zeugt. Er ist zudem Ausdruck des unterschiedlichen Umgangs der Nachgeborenen mit ihrem Kulturgut. Außerdem ist dieser Jüdische Friedhof zurzeit als einziger in Deutschland durch die UNESCO als Welterbe anerkannt.

Vor 120 Jahren wurde das Gelände südlich des damaligen Bahnhofs Neubabelsberg erstmals bebaut. Aus dem 1896 errichteten Depot für Lazarett-Baracken entwickelte sich bis 1938 die logistische Zentrale des Deutschen Roten Kreuzes, das ab 1939 auch sein Präsidium nach Babelsberg verlegte. Nach einer Zwischennutzung ab 1945 durch die sowjetische Besatzungsarmee war von 1952 bis zur Wende die Akademie für Staats- und Rechtswissenschaften als „Kaderschmiede“ der Hausherr des nun im Grenzgebiet zu Westberlin liegenden Areals. Heute nutzen die Universität Potsdam und das Hasso-Plattner-Institut für Software-Systemtechnik den Campus, dessen Geschichte mit dieser Publikation erstmals umfassend dokumentiert wird.

Design and Implementation of service-oriented architectures imposes a huge number of research questions from the fields of software engineering, system analysis and modeling, adaptability, and application integration. Component orientation and web services are two approaches for design and realization of complex web-based system. Both approaches allow for dynamic application adaptation as well as integration of enterprise application.
Commonly used technologies, such as J2EE and .NET, form de facto standards for the realization of complex distributed systems. Evolution of component systems has lead to web services and service-based architectures. This has been manifested in a multitude of industry standards and initiatives such as XML, WSDL UDDI, SOAP, etc. All these achievements lead to a new and promising paradigm in IT systems engineering which proposes to design complex software solutions as collaboration of contractually defined software services.
Service-Oriented Systems Engineering represents a symbiosis of best practices in object-orientation, component-based development, distributed computing, and business process management. It provides integration of business and IT concerns.
The annual Ph.D. Retreat of the Research School provides each member the opportunity to present his/her current state of their research and to give an outline of a prospective Ph.D. thesis. Due to the interdisciplinary structure of the research school, this technical report covers a wide range of topics. These include but are not limited to: Human Computer Interaction and Computer Vision as Service; Service-oriented Geovisualization Systems; Algorithm Engineering for Service-oriented Systems; Modeling and Verification of Self-adaptive Service-oriented Systems; Tools and Methods for Software Engineering in Service-oriented Systems; Security Engineering of Service-based IT Systems; Service-oriented Information Systems; Evolutionary Transition of Enterprise Applications to Service Orientation; Operating System Abstractions for Service-oriented Computing; and Services Specification, Composition, and Enactment.
