T1 - Upper Palaeolithic genomes reveal deep roots of modern Eurasians T2 - Zweitveröffentlichungen der Universität Potsdam : Mathematisch-Naturwissenschaftliche Reihe N2 - We extend the scope of European palaeogenomics by sequencing the genomes of Late Upper Palaeolithic (13,300 years old, 1.4-fold coverage) and Mesolithic (9,700 years old, 15.4-fold) males from western Georgia in the Caucasus and a Late Upper Palaeolithic (13,700 years old, 9.5-fold) male from Switzerland. While we detect Late Palaeolithic–Mesolithic genomic continuity in both regions, we find that Caucasus hunter-gatherers (CHG) belong to a distinct ancient clade that split from western hunter-gatherers ∼45 kya, shortly after the expansion of anatomically modern humans into Europe and from the ancestors of Neolithic farmers ∼25 kya, around the Last Glacial Maximum. CHG genomes significantly contributed to the Yamnaya steppe herders who migrated into Europe ∼3,000 BC, supporting a formative Caucasus influence on this important Early Bronze age culture. CHG left their imprint on modern populations from the Caucasus and also central and south Asia possibly marking the arrival of Indo-Aryan languages.

However, which particular exercise intervention can minimize the age-related gait speed loss is unclear. Purpose: Our objective was to determine the effects of strength, power, coordination, and multimodal exercise training on healthy old adults' habitual and fast gait speed. Methods: We performed a computerized systematic literature search in PubMed and Web of Knowledge from January 1984 up to December 2014. Search terms included 'Resistance training', 'power training', 'coordination training', 'multimodal training', and 'gait speed (outcome term). Inclusion criteria were articles available in full text, publication period over past 30 years, human species, journal articles, clinical trials, randomized controlled trials, English as publication language, and subject age C65 years. The methodological quality of all eligible intervention studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. We computed weighted average standardized mean differences of the intervention-induced adaptations in gait speed using a random-effects model and tested for overall and individual intervention effects relative to no-exercise controls. Results: A total of 42 studies (mean PEDro score of 5.0 +/- 1.2) were included in the analyses (2495 healthy old adults; age 74.2 years [64.4-82.7]; body mass 69.9 +/- 4.9 kg, height 1.64 +/- 0.05 m, body mass index 26.4 +/- 1.9 kg/m(2), and gait speed 1.22 +/- 0.18 m/s). The search identified only one power training study, therefore the subsequent analyses focused only on the effects of resistance, coordination, and multimodal training on gait speed. The three types of intervention improved gait speed in the three experimental groups combined (n = 1297) by 0.10 m/s (+/- 0.12) or 8.4 % (+/- 9.7), with a large effect size (ES) of 0.84. Resistance (24 studies; n = 613; 0.11 m/s; 9.3 %; ES: 0.84), coordination (eight studies, n = 198; 0.09 m/s; 7.6 %; ES: 0.76), and multimodal training (19 studies; n = 486; 0.09 m/s; 8.4 %, ES: 0.86) increased gait speed statistically and similarly. Conclusions: Commonly used exercise interventions can functionally and clinically increase habitual and fast gait speed and help slow the loss of gait speed or delay its onset.

T1 - Endogenous murine leukemia retroviral variation across wild European and inbred strains of house mouse T2 - Zweitveröffentlichungen der Universität Potsdam : Mathematisch-Naturwissenschaftliche Reihe N2 - Background: Endogenous murine leukemia retroviruses (MLVs) are high copy number proviral elements difficult to comprehensively characterize using standard low throughput sequencing approaches. However, high throughput approaches generate data that is challenging to process, interpret and present. Results: Next generation sequencing (NGS) data was generated for MLVs from two wild caught Mus musculus domesticus (from mainland France and Corsica) and for inbred laboratory mouse strains C3H, LP/J and SJL. Sequence reads were grouped using a novel sequence clustering approach as applied to retroviral sequences. A Markov cluster algorithm was employed, and the sequence reads were queried for matches to specific xenotropic (Xmv), polytropic (Pmv) and modified polytropic (Mpmv) viral reference sequences. Conclusions: Various MLV subtypes were more widespread than expected among the mice, which may be due to the higher coverage of NGS, or to the presence of similar sequence across many different proviral loci. The results did not correlate with variation in the major MLV receptor Xpr1, which can restrict exogenous MLVs, suggesting that endogenous MLV distribution may reflect gene flow more than past resistance to infection.

In order to explain this puzzling social phenomenon, we have to take secrecy – the characteristic trait of modern torture – as the lynchpin of the analysis. Following Georg Simmel’s formal analysis of the “secret society”, the contribution reconstructs structural and cultural aspects of the secret society of torturers that generate social processes that allow its members to behave extremely violently, forcing individuals to turn into torturers. The contribution argues that the form of social behaviour that we call torture is socially shaped.

Created in the aftermath of World War II by its victors, the UNSC’s constellation looks increasingly anachronistic, however, in light of the changing global distribution of power. Adapting the institutional structure and decision-making procedures of the UNSC has proven to be one of the most difficult challenges of the last decades, while it is the institution that has probably been faced with the most vociferous calls for reform. Although there have been changes to the informal ways in which outside actors are drawn into the UNSC’s work and activities, many of the major players in the current international system seem to be deprived from equal treatment in its core patterns of decision-making. Countries such as Brazil, Germany, India and Japan, alongside emerging African nations such as Nigeria and South Africa, are among the states eager to secure permanent representation on the Council. By comparison, selected BRICS countries, China and Russia - in contrast to their role in other multilateral institutions - are permanent members of the UNSC and with this, have been “insiders” for a long time. This renders the situation of the UNSC different from global institutions, in which traditionally, Western powers have dominated the agenda.

Der Historiker Xenophon von Athen (427–ca. 355 v. Chr.) hat in seinen Schriften über zwei Träger dieses Namens berichtet und sie durchaus unterschiedlich bewertet: Kyros II. («der Große»), Mehrer des Reiches, sowie ein Jahrhundert später Kyros, Sohn des Dareios und jüngerer Bruder des Perserkönigs Artaxerxes II. Der ältere Kyros ist namengebender Protagonist eines Fürstenspiegels (der Kyropädie), wird also grundsätzlich positiv und als ein Vorbild für andere dargestellt. Am erfolglosen Kampf des jüngeren Kyros um die Krone des Perserreichs hatte Xenophon als Offizier griechischer Söldner selbst teilgenommen. Aus dem Vergleich von Darstellung und Bewertung der beiden Fürsten lassen sich die Ansprüche Xenophons an einen idealen Herrscher ableiten, was hier unternommen werden soll. Zugleich ermöglichen diese Ergebnisse, Xenophon als Historiker und politischen Denker in der zeitgenössischen Debatte um die beste Staatsform einzubetten. N2 - «Cyrus» as the name of a prince occurs thrice in the annals of the Persian Empire. e historian Xenophon of Athens (427–about 355 BC) wrote about two bearers of that name: Cyrus II. («the Great») and, roughly a century later, the younger Cyrus, son of Darius II. and younger brother of Artaxerxes II., the Persian king. e older Cyrus gives his name to a mirror of princes (the Cyrupaedia) and is portrayed positively and as an inspiration to others. Xenophon himself had been an officer in the failed attempt of the younger Cyrus to win the Persian throne by military force. By comparing the way Xenophon depicts and judges both princes, we can deduct what our historian expected of an ideal ruler. ese expectations place Xenophon in the wide contemporary spectrum of opinions on the best constitution (monarchy, oligarchy, democracy).

Current NMSs rely heavily on active scanning techniques for discovering and mapping network information. Although this approach works, it introduces some major drawbacks such as the performance impact it can exact, specially in larger network environments. As a consequence, scans are often run less frequently which can result in stale information being presented and used by the network monitoring system. Alternatively, some NMSs rely on their agents being deployed on the hosts they monitor. In this article, we present a new approach to Network Topology Discovery and Network Inventory Listing using only passive monitoring and scanning techniques. The proposed techniques rely solely on the event logs produced by the hosts and network devices present within a network. Finally, we discuss some of the advantages and disadvantages of our approach.

In this paper we study the reciprocal class of compound Poisson processes whose jumps belong to a finite set . We propose a characterization of the reciprocal class as the unique set of probability measures on which a family of time and space transformations induces the same density, expressed in terms of the reciprocal invariants. The geometry of plays a crucial role in the design of the transformations, and we use tools from discrete geometry to obtain an optimal characterization. We deduce explicit conditions for two Markov jump processes to belong to the same class. Finally, we provide a natural interpretation of the invariants as short-time asymptotics for the probability that the reference process makes a cycle around its current state.

The programme combines anti-bias methods relating to linguistic diversity with objectives of raising critical language awareness. Evaluation through teachers' workshops in Berlin and Brandenburg points to positive and enduring attitudinal changes in participants, but not in control groups that did not attend workshops, and effects were independent of personal variables gender and teaching subject and only weakly associated with age. We relate these effects to such programme features as indirect and inclusive methods that foster active engagement, and the combination of ‘safer’ topics targeting attitudes towards linguistic structures with more challenging ones dealing with the discrimination of speakers.

Both contributions focus on so-called particle filters. The first contribution by Jan van Leeuwen focuses on the potential of proposal densities. It discusses the issues with present-day particle filters and explorers new ideas for proposal densities to solve them, converging to particle filters that work well in systems of any dimension, closing the contribution with a high-dimensional example. The second contribution by Cheng and Reich discusses a unified framework for ensemble-transform particle filters. This allows one to bridge successful ensemble Kalman filters with fully nonlinear particle filters, and allows a proper introduction of localization in particle filters, which has been lacking up to now.

Extensive Monte Carlo simulations of the motion of tracer particles on an ensemble of realisations of percolation clusters are performed for a wide range of percolation densities. Single trajectories of the tracer motion are analysed to quantify the time averaged mean squared displacement (MSD) and to compare this with the ensemble averaged MSD of the particle motion. Other complementary physical observables associated with ergodicity are studied, as well. It turns out that the time averaged MSD of individual realisations exhibits non-vanishing fluctuations even in the limit of very long observation times as the percolation density approaches the critical value. This apparent non-ergodic behaviour concurs with the ergodic behaviour on the ensemble averaged level. We demonstrate how the non-vanishing fluctuations in single particle trajectories are analytically expressed in terms of the fractal dimension and the cluster size distribution of the random geometry, thus being of purely geometrical origin. Moreover, we reveal that the convergence scaling law to ergodicity, which is known to be inversely proportional to the observation time T for ergodic diffusion processes, follows a power-law ∼T−h with h < 1 due to the fractal structure of the accessible space. These results provide useful measures for differentiating the subdiffusion on random fractals from an otherwise closely related process, namely, fractional Brownian motion. Implications of our results on the analysis of single particle tracking experiments are provided.

Understanding how such species have responded to past glacial cycles can help us forecast their response to today's changing climate. Gray whales are among those marine species likely to be strongly affected by Arctic climate change, but a thorough analysis of past climate impacts on this species has been complicated by lack of information about an extinct population in the Atlantic. While little is known about the history of Atlantic gray whales or their relationship to the extant Pacific population, the extirpation of the Atlantic population during historical times has been attributed to whaling. We used a combination of ancient and modern DNA, radiocarbon dating and predictive habitat modelling to better understand the distribution of gray whales during the Pleistocene and Holocene. Our results reveal that dispersal between the Pacific and Atlantic was climate dependent and occurred both during the Pleistocene prior to the last glacial period and the early Holocene immediately following the opening of the Bering Strait. Genetic diversity in the Atlantic declined over an extended interval that predates the period of intensive commercial whaling, indicating this decline may have been precipitated by Holocene climate or other ecological causes. These first genetic data for Atlantic gray whales, particularly when combined with predictive habitat models for the year 2100, suggest that two recent sightings of gray whales in the Atlantic may represent the beginning of the expansion of this species' habitat beyond its currently realized range.

To date, over 30 ancient genomes have been sequenced, moving from 0.7x coverage (mammoth) in 2008 to more than 50x coverage (Neanderthal) in 2014. Studies of rapid evolutionary changes, such as the evolution and spread of pathogens and the genetic responses of hosts, or the genetics of domestication and climatic adaptation, are developing swiftly and the importance of palaeogenomics for investigating evolutionary processes during the last million years is likely to increase considerably. However, these new datasets require new methods of data processing and analysis, as well as conceptual changes in interpreting the results. In this review we highlight important areas of future technical and conceptual progress and discuss research topics in the rapidly growing field of palaeogenomics.

Methods Systematic literature review and meta-analysis. Results Whole body vibration combined with exercise had an overall 0.3 % acute effect on maximal voluntary leg force (−6.4 %, effect size = −0.43, 1 study), leg power (4.7 %, weighted mean effect size = 0.30, 6 studies), flexibility (4.6 %, effect size = −0.12 to 0.22, 2 studies), and athletic performance (−1.9 %, weighted mean effect size = 0.26, 6 studies) in 191 (103 male, 88 female) athletes representing eight sports (overall effect size = 0.28). Whole body vibration combined with exercise had an overall 10.2 % chronic effect on maximal voluntary leg force (14.6 %, weighted mean effect size = 0.44, 5 studies), leg power (10.7 %, weighted mean effect size = 0.42, 9 studies), flexibility (16.5 %, effect size = 0.57 to 0.61, 2 studies), and athletic performance (−1.2 %, weighted mean effect size = 0.45, 5 studies) in 437 (169 male, 268 female) athletes (overall effect size = 0.44). Conclusions Whole body vibration has small and inconsistent acute and chronic effects on athletic performance in competitive and/or elite athletes. These findings lead to the hypothesis that neuromuscular adaptive processes following whole body vibration are not specific enough to enhance athletic performance. Thus, other types of exercise programs (e.g., resistance training) are recommended if the goal is to improve athletic performance.

T1 - Regional ICT innovation in the European Union BT - prioritization and performance (2008–2012) T2 - Postprints der Universität Potsdam : Wirtschafts- und Sozialwissenschaftliche Reihe N2 - In the current programming period, European Union (EU) regions and member states that want to use European Regional Development Funds (ERDF) are required to develop innovation strategies for smart specialization (RIS3) based on the idea of rational strategic management. In order to explore the relationship between strategic policy design and policy performance, this article maps regional strategies for information and communication technologies (ICT) and their effects in the period 2008–2012. Furthermore, it generates suggestions for relevant case studies. We first conduct a quantitative analysis of the effects of ICT strategies and ERDF expenditure on regional ICT performance in Western European regions. ICT is a relevant priority for many regions, and it reflects EU priorities fostering ICT activities through regional development funds. Second, we propose a framework to categorize EU regions in the context of ICT policy based on the expected distribution of regional ICT performance. Our analysis covers 97 regions in 9 EU member states, out of which 29 have had a dedicated ICT strategy. In line with ideas of rational strategic management, our working hypothesis states that regions with a dedicated strategy should display better performance. However, our findings suggest that having a dedicated ICT strategy has not had a clear effect on performance in terms of Internet and broadband access, while allocating dedicated ERDF and other expenditure to Internet infrastructure has had a positive effect. At first sight, this questions the effectiveness of rational strategic management. Yet, more research is needed to assess the quality of ICT strategies and their fit with broader innovation agendas. It is indeed the degree of embeddedness of ICT in the regional innovation ecosystem that is likely to condition the effect of strategies on performance. To this end, our mapping indicates interesting case studies, and we suggest additional factors to be taken into account in future analyses. New insights into strategy design and performance will also be important to inform the implementation of the new generation of innovation strategies for smart specialization.

Based on the principle of limiting factors, VSL combines temperature and moisture time series in a nonlinear fashion to obtain simulated TRW chronologies. When used as observation operator, this modelling approach implies three compounding, challenging features: (1) time averaging, (2) “switching recording” of 2 variables and (3) bounded response windows leading to “thresholded response”. We generate pseudo-TRW observations from a chaotic 2-scale dynamical system, used as a cartoon of the atmosphere-land system, and attempt to assimilate them via ensemble Kalman filtering techniques. Results within our simplified setting reveal that VSL’s nonlinearities may lead to considerable loss of assimilation skill, as compared to the utilization of a time-averaged (TA) linear observation operator. In order to understand this undesired effect, we embed VSL’s formulation into the framework of fuzzy logic (FL) theory, which thereby exposes multiple representations of the principle of limiting factors. DA experiments employing three alternative growth rate functions disclose a strong link between the lack of smoothness of the growth rate function and the loss of optimality in the estimate of the TA state. Accordingly, VSL’s performance as observation operator can be enhanced by resorting to smoother FL representations of the principle of limiting factors. This finding fosters new interpretations of tree-ring-growth limitation processes.

This article argues that an important yet missing piece of this puzzle is the systematic exploration of the political use of policy knowledge. While much of the recent debate has focused on the question of how the substantive use of knowledge can improve the quality of policy choices, our understanding of the political use of knowledge and its effects in the policy process has remained deficient in key respects. A revised conceptualization of the political use of knowledge is introduced that emphasizes how conflicting knowledge can be used to contest given structures of policy authority. This allows the analysis to differentiate between knowledge creep and knowledge shifts as two distinct types of knowledge effects in the policy process. While knowledge creep is associated with incremental policy change within existing policy structures, knowledge shifts are linked to more fundamental policy change in situations when the structures of policy authority undergo some level of transformation. The article concludes by identifying characteristics of the administrative structure of policy systems or sectors that make knowledge shifts more or less likely.

This species is an established model system in the study of the genetics, evolution, and ecology of heterostylous floral polymorphisms. Despite the long history of research focused on this and related species, the continued development of this system has been restricted due the absence of genomic and transcriptomic resources. Results We present here a de novo draft genome assembly of P. veris covering 301.8 Mb, or approximately 63% of the estimated 479.22 Mb genome, with an N50 contig size of 9.5 Kb, an N50 scaffold size of 164 Kb, and containing an estimated 19,507 genes. The results of a RADseq bulk segregant analysis allow for the confident identification of four genome scaffolds that are linked to the P. veris S-locus. RNAseq data from both P. veris and the closely related species P. vulgaris allow for the characterization of 113 candidate heterostyly genes that show significant floral morph-specific differential expression. One candidate gene of particular interest is a duplicated GLOBOSA homolog that may be unique to Primula (PveGLO2), and is completely silenced in L-morph flowers. Conclusions The P. veris genome represents the first genome assembled from a heterostylous species, and thus provides an immensely important resource for future studies focused on the evolution and genetic dissection of heterostyly. As the first genome assembled from the Primulaceae, the P. veris genome will also facilitate the expanded application of phylogenomic methods in this diverse family and the eudicots as a whole.

A new paleomagnetic database for lake and marine sediments T2 - Postprints der Universität Potsdam : Mathematisch Naturwissenschaftliche Reihe N2 - Background: GEOMAGIA50.v3 for sediments is a comprehensive online database providing access to published paleomagnetic, rock magnetic, and chronological data obtained from lake and marine sediments deposited over the past 50 ka. Its objective is to catalogue data that will improve our understanding of changes in the geomagnetic field, physical environments, and climate. Findings: GEOMAGIA50.v3 for sediments builds upon the structure of the pre-existing GEOMAGIA50 database for magnetic data from archeological and volcanic materials. A strong emphasis has been placed on the storage of geochronological data, and it is the first magnetic archive that includes comprehensive radiocarbon age data from sediments. The database will be updated as new sediment data become available. Conclusions: The web-based interface for the sediment database is located at http://geomagia.gfz-potsdam.de/geomagiav3/SDquery.php. This paper is a companion to Brown et al. (Earth Planets Space doi:10.1186/s40623-015-0232-0,2015) and describes the data types, structure, and functionality of the sediment database.

Parallel to the decrease in physical activity and locomotion, modern people are slimmer in skeletal proportions. In German children and adolescents, elbow breadth and particularly relative pelvic breadth (50th centile of bicristal distance divided by body height) have significantly decreased in recent years. Even more evident than the changes in pelvic morphology are the rapid changes in body height in most modern countries since the end-19th and particularly since the mid-20th century. Modern Japanese mature earlier; the age at take-off (ATO, the age at which the adolescent growth spurt starts) decreases, and they are taller at all ages. Preece-Baines modelling of six national samples of Japanese children and adolescents, surveyed between 1955 and 2000, shows that this gain in height is largely an adolescent trend, whereas height at take-off (HTO) increased by less than 3 cm since 1955; adolescent growth (height gain between ATO and adult age) increased by 6 cm. The effect of globalization on the modern post-war Japanese society ("community effect in height") on adolescent growth is discussed.

Parents have to leave their young unattended for foraging trips, during which nestlings are exposed to predators. We investigated how rodent mothers of altricial young respond to risk of nest predation in their foraging decisions. We studied foraging behavior of lactating bank voles (Myodes glareolus) exposed to a nest predator, the common shrew (Sorex araneus). We conducted the experiment in summer (high resource provisioning for both species) and autumn (less food available) in 12 replicates with fully crossed factors “shrew presence” and “season.” We monitored use of feeding stations near and far from the nest as measurement of foraging activity and strategic foraging behavior. Vole mothers adapted their strategies to shrew presence and optimized their foraging behavior according to seasonal constraints, resulting in an interaction of treatment and season. In summer, shrew presence reduced food intake from feeding stations, while it enhanced intake in autumn. Shrew presence decreased the number of visited feeding stations in autumn and concentrated mother’s foraging efforts to fewer stations. Independent of shrew presence or season, mothers foraged more in patches further away from the nest than near the nest. Results indicate that females are not investing in nest guarding but try to avoid the accumulation of olfactory cues near the nest leading a predator to the young. Additionally, our study shows how foraging strategies and nest attendance are influenced by seasonal food provision.

Scepticism in this field was only matched by the long-lasting controversy over the authenticity of ancient pathogen DNA. This ambiguous view on ancient human DNA had a dichotomous root. On the one hand, the interest in ancient human DNA is great because such studies touch on the history and evolution of our own species. On the other hand, because these studies are dealing with samples from our own species, results are easily compromised by contamination of the experiments with modern human DNA, which is ubiquitous in the environment. Consequently, some of the most disputed studies published - apart maybe from early reports on million year old dinosaur or amber DNA - reported DNA analyses from human subfossil remains. However, the development of so-called next- or second-generation sequencing (SGS) in 2005 and the technological advances associated with it have generated new confidence in the genetic study of ancient human remains. The ability to sequence shorter DNA fragments than with PCR amplification coupled to traditional Sanger sequencing, along with very high sequencing throughput have both reduced the risk of sequencing modern contamination and provided tools to evaluate the authenticity of DNA sequence data. The field is now rapidly developing, providing unprecedented insights into the evolution of our own species and past human population dynamics as well as the evolution and history of human pathogens and epidemics. Here, we review how recent technological improvements have rapidly transformed ancient human DNA research from a highly controversial subject to a central component of modern anthropological research. We also discuss potential future directions of ancient human DNA research.

Das zeigt sich unter anderem an der Zahl der Studieninteressierten. So haben sich allein in diesem Jahr mehr als 1 500 junge Leute auf einen der 44 Plätze für den Studiengang Medienwissenschaft an der Universität Potsdam beworben. Nach ihrem erfolgreichen Abschluss allerdings konkurrieren die Absolventen am Arbeitsmarkt mit Tausenden Abgängern anderer Hochschulen aus Film-, Medien- und Kommunikationsstudiengängen. Das sind allein in der Region Berlin-Brandenburg jährlich etwa 1 500. Doch nach jahrzehntelangem Boom der Medienbranche hat sich der Arbeitsmarkt im vergangenen Jahrzehnt drastisch verändert. Konjunkturkrise, Kursrückgänge und rückläufige Werbeinvestitionen schwächten die Medien deutlich. Es folgten daraus schlechte Gewinnergebnisse, Einsparungen und Personalreduzierung, insbesondere bei den Printmedien. Die Insolvenz der Frankfurter Rundschau oder die Einstellung der Financial Times Deutschland sind nur zwei eklatante Beispiele. Auf der anderen Seite boomt der dynamische Online-Markt aufgrund des veränderten Nutzerverhaltens insbesondere der jungen Generation, die ihre Informationen zunehmend aus Internet, Apps und sozialen Netzwerken gewinnen. Die Berufsaussichten für all Jene, die „Irgendwas mit Medien“ studieren wollen sind zwar aufgrund des Arbeitsmarktes schwieriger geworden, sie sind aber dennoch vielfältig. Guter Journalismus wird weiterhin benötigt und auch Öffentlichkeitsarbeiter sind gefragt. Darüber hinaus stehen Absolveninspiriert von den Fernsehbildern, als Tausende Flüchtlinge herzlich in München empfangen wurden, kam unserem Kollegen Eric Makswitat die Idee, sich auch auf lokaler Ebene für die hier ankommenden Flüchtlinge zu engagieren. Der Doktorand in der Politikwissenschaft sammelt über das Internet Bücher für Flüchtlinge und gibt sie dann direkt in den Flüchtlingsunterkünften ab. Eric Makswitat ist einer von Vielen, die derzeit einen wichtigen Beitrag zur Bewältigung der Herausforderungen des Flüchtlingszustroms nach Deutschland leisten. Die engagierten Helfer sind „ein Beweis dafür, wie weit die Selbstorganisationskräfte der organisierten Bürgerschaft in unserer Zivilgesellschaft mittlerweile entwickelt sind“, meint dazu der Verwaltungswissenschaftler Jochen Franzke. Unser Kollege Eric ist auch in anderer Hinsicht beispielgebend. Er ist einer von rund achtzig Prozent aller ehemaligen Studierenden, die nach dem Studienabschluss in der Region bleiben, wie eine kürzlich an der Uni veröffentlichte Studie zum Verbleib unserer Absolventinnen und Absolventen ermittelt hat. Unsere Alumni steigen ein in Berufsfeldern der Politik, Wirtschaft und Gesellschaft, sie gründen Firmen und sie engagieren sich beruflich, privat oder gesellschaftlich. Viele davon in Potsdam. Wenn die Universität Potsdam im nächsten Jahr ihr 25-jähriges Jubiläum in und mit der Stadt Potsdam feiern wird und mit Stolz auf hervorragende Leistungen aus Lehre und Forschung verweist, dann ist dies nicht zuletzt den Absolventinnen und Absolventen zu verdanken, die als hochqualifizierte Fachkräfte neueste wissenschaftliche Erkenntnisse in die Praxis überführen. Portal alumni ist deshalb in diesem Jahr hier, zu Hause in Potsdam geblieben. Wir haben Absolventen der Universität Potsdam gesucht, die heute in unterschiedlichen beruflichen und gesellschaftlichen Kontexten in der Region aktiv sind und sich engagieren.

The concept is relatively straightforward but usage and interpretation has been different across studies. While no thresholds exist for evaluating the degree of improvement, many studies have relied solely on the significance of the NRI estimate. However, recent studies recommend that statistical testing with the NRI should be avoided. We propose using confidence ellipses around the estimated values of event and non-event NRIs which might provide the best measure of variability around the point estimates. Our developments are illustrated using practical examples from EPIC-Potsdam study.

Compared to the general population, medical students are at a greater risk of developing a psychological disorder. Various attempts of stress management training in medical school have achieved positive results on minimizing psychological distress; however, there are often limitations. Therefore, the use of a rigorous scientific method is needed. The present study protocol describes a randomized controlled trial to examine the effectiveness of a specifically developed mindfulness-based stress prevention training for medical students that includes selected elements of cognitive behavioral strategies (MediMind). Methods/Design: This study protocol presents a prospective randomized controlled trial, involving four assessment time points: baseline, post-intervention, one-year follow-up and five-year follow-up. The aims include evaluating the effect on stress, coping, psychological morbidity and personality traits with validated measures. Participants are allocated randomly to one of three conditions: MediMind, Autogenic Training or control group. Eligible participants are medical or dental students in the second or eighth semester of a German university. They form a population of approximately 420 students in each academic term. A final total sample size of 126 (at five-year follow-up) is targeted. The trainings (MediMind and Autogenic Training) comprise five weekly sessions lasting 90 minutes each. MediMind will be offered to participants of the control group once the five-year follow-up is completed. The allotment is randomized with a stratified allocation ratio by course of studies, semester, and gender. After descriptive statistics have been evaluated, inferential statistical analysis will be carried out with a repeated measures ANOVA-design with interactions between time and group. Effect sizes will be calculated using partial η-square values. Discussion: Potential limitations of this study are voluntary participation and the risk of attrition, especially concerning participants that are allocated to the control group. Strengths are the study design, namely random allocation, follow-up assessment, the use of control groups and inclusion of participants at different stages of medical training with the possibility of differential analysis.

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

T1 - Trade-offs between tRNA abundance and mRNA secondary structure support smoothing of translation elongation rate T2 - Postprints der Universität Potsdam : Mathematisch-Naturwissenschaftliche Reihe N2 - Translation of protein from mRNA is a complex multi-step process that occurs at a non-uniform rate. Variability in ribosome speed along an mRNA enables refinement of the proteome and plays a critical role in protein biogenesis. Detailed single protein studies have found both tRNA abundance and mRNA secondary structure as key modulators of translation elongation rate, but recent genome-wide ribosome profiling experiments have not observed significant influence of either on translation efficiency. Here we provide evidence that this results from an inherent trade-off between these factors. We find codons pairing to high-abundance tRNAs are preferentially used in regions of high secondary structure content, while codons read by significantly less abundant tRNAs are located in lowly structured regions. By considering long stretches of high and low mRNA secondary structure in Saccharomyces cerevisiae and Escherichia coli and comparing them to randomized-gene models and experimental expression data, we were able to distinguish clear selective pressures and increased protein expression for specific codon choices. The trade-off between secondary structure and tRNA-concentration based codon choice allows for compensation of their independent effects on translation, helping to smooth overall translational speed and reducing the chance of potentially detrimental points of excessively slow or fast ribosome movement.

We use or encounter them every day in various areas. They represent perceptions and ideas: A letter represents a sound, a word or picture stands for an idea, a note for a sound, a chemical formula for a substance, a boundary stone for a territorial claim, a building for an ideology, a gesture for a cue or an assessment. On the one hand, we open up the world to ourselves by using signs; we acquire it, ensconce ourselves in it, and we punctuate it to represent ourselves in it. On the other, this reference to the world and ourselves becomes visible in our sign systems. As manifestations of a certain way of interacting with nature, the environment, and fellow human beings, they provide information about the social order or ethnic distinctions of a certain society or epoch as well as about how it perceives the world and humanity. As a man-made network of meanings, sign systems can be changed and, in doing so, change how we perceive the world and humanity. Linguistically, this may, for example, be done by using an evaluative prefix: human – inhuman, sense – nonsense, matter – anti-matter or by hierarchizing terms, as in upper class and lower class. The consequences of such labeling, therefore, may decide on the raison d'être of the signified within an aspect of reality and the nature of this existence. Since ancient times we have reflected on signs, at first mainly in philosophy. Each era has created theories of signs as a means of approaching its essence. Nowadays semiotics is especially concerned with them. While linguistics focuses on linguistic signs, semiotics deals with all types of signs and the interaction of components and processes involved in their communication. Semiotics has developed models, methods, and concepts. Semiosis and semiosphere, for example, are concepts that illuminate the processing of signs, i.e. the construction of meaning and the interaction of different sign systems. A sign is not limited to a monolithic meaning but is culturally contingent and marked by the socioeconomic conditions of the individual decoding it. Sociopolitical and sociocultural developments therefore affect the processing of signs. Dealing with signs and sign systems, their circulation, and reciprocal play with shapes and interpretive possibilities is therefore an urgent and trailblazing task in light of sociocultural communication processes in our increasingly heterogeneous society to optimize communication and promote intercultural understanding as well as to recognize, use, and bolster social trends. The articles in this magazine illustrate the many ways academia is involved in researching, interpreting, and explaining signs. Social scientists at the University of Potsdam are examining whether statistics about petitions made by GDR citizens can be interpreted retrospectively as a premonitory sign of the peaceful revolution of 1989. Colleagues at the Institute of Romance Studies are analyzing what Alexander von Humboldt’s American travel diaries signalize, and young researchers in the Research Training Group on “Wicked Problems, Contested Administrations” are examining challenges that seem to raise question marks for administrations. A project promoting sustainable consumption hopes to prove that academia can contribute to setting an example. An initiative of historians supporting Brandenburg cities in disseminating the history of the Reformation shows that the gap between academia and signs and wonder is not unbridgeable.

Over millions of years, genetic differentiation has brought about an incredible diversity of species. Evolution has followed many different paths. It has led to an awesome natural biodiversity – to organisms that have adapted to very different environments and are sometimes oddly shaped or behave strangely. Humanmade biodiversity is stunning, too. Just think of the 10,000 rose varieties whose beauty delights, or the myriad wheat, barley, and corn variations; plants that had all once been plain grasses feed us today. We humans create our own biodiversity unknown to nature. And it is serving us well. Thanks to genome research we are now able to read the complete genetic information of organisms within a few hours or days. It takes much longer, however, to functionally map the many genomic sequences. Researchers achieve this through various methods: Activating or deactivating genes systematically, modifying their code, and exchanging genetic information between organisms have become standard procedures worldwide. The path to knowledge is often intricate, though. Elaborate experimental approaches are often necessary to gain insight into biological processes. Methods of genomic research enable us to investigate not only what is “out there” in nature, but also to ask, “How does a living organism, like a moss, react when sent to the International Space Station (ISS)? Can we gain knowledge about the adaptation strategies of living beings in harsh environmental conditions or even for colonizing the Moon or Mars?” Can we use synthetic biology to precisely alter microorganisms, planned on a drawing board so to speak, to create new options for treating diseases or for making innovative biology-based products? The answer to both questions is a resounding Yes! (Although moving to other planets is not on our present agenda.) Human land use determines biodiversity. On the other hand, organisms influence the formation of landscapes and, sooner or later, the composition of our atmosphere. This also leads to exciting scientific questions. Researchers have to strike new paths to reach new conclusions. Paths often cross other paths. A few years ago it was still unforeseeable that ecological research would substantially benefit from fast DNA sequencing methods. Genome researchers could hardly assume that the same techniques would lead to new possibilities for examining the highly complex cellular regulation and optimizing biotechnological processes. You will find examples of the multi-faceted research in biology as well as other very interesting articles in the latest edition of Portal Wissen. I wish you an enjoyable read!

Wir nutzen sie oder begegnen ihnen tagtäglich in verschiedenen Bereichen. Sie sind Stellvertreter für Wahrnehmungen und Vorstellungen: Ein Buchstabe steht für einen Laut, ein Wort oder Bild für eine Vorstellung, eine Note für einen Ton, eine chemische Formel für einen Stoff, ein Grenzstein für einen Gebietsanspruch, ein Bauwerk für eine Ideologie, eine Geste für einen Hinweis oder eine Bewertung usw. Einerseits erschließen wir uns mit Zeichen die Welt, eignen sie uns an, richten uns in ihr ein und stellen uns in ihr mittels Zeichensetzung dar. Anderseits wird diese Bezugnahme auf Welt und uns selbst durch unsere Zeichensysteme sichtbar. Als Ausdruck eines spezifischen Umgangs mit Natur, Umwelt und Mitmensch geben sie Auskunft über Welt- und Menschenbilder einer Gesellschaft oder Epoche, über ihre sozialen Ordnungen oder ethnischen Abgrenzungen. Als ein vom Menschen geschaffenes Netzwerk von Bedeutungen können Zeichensysteme verändert werden und mit ihnen auch Welt- und Menschenbilder. Auf sprachlicher Ebene kann dies beispielsweise durch eine wertende Vorsilbe geschehen: Kraut – Unkraut, Mensch – Unmensch, Sinn – Unsinn, oder durch hierarchisierende Begriffe wie Ober- und Unterschicht. Die Konsequenzen solcher Etikettierungen entscheiden also unter Umständen über die Daseinsberechtigung des Bezeichneten innerhalb eines Wirklichkeitsausschnitts und über die Art dieses Daseins. Über Zeichen wird bereits seit der Antike nachgedacht, zunächst vor allem in der Philosophie. Jede Epoche hat ihre Theorien von Zeichen hervorgebracht, um sich ihrem Wesen zu nähern. Heute befasst sich insbesondere die Semiotik mit ihnen. Während sich die Linguistik auf sprachliche Zeichen konzentriert, widmet sich die Semiotik allen Zeichenarten und dem Zusammenspiel der Komponenten und Prozesse, die an ihrer Vermittlung beteiligt sind. Sie hat dafür Modelle, Methoden und Konzepte entwickelt. Mit den Konzepten der Semiose sowie der Semiosphäre beispielsweise lassen sich der Prozess der Zeichenverarbeitung, d.h. der Sinnkonstruktion, bzw. das Zusammenwirken verschiedener Zeichensysteme beleuchten. Ein eindeutiger Sinn haftet einem Zeichen nicht an, er wird kulturell und durch die jeweiligen soziökonomischen Rahmenbedingungen des entschlüsselnden Individuums mitgeprägt. Gesellschaftspolitische und soziokulturelle Entwicklungen wirken sich daher auf die Zeichenverarbeitung aus. Sich mit Zeichen und Zeichensystemen zu befassen, mit ihrer Zirkulation und dem dabei zu beobachtenden wechselseitigen Spiel mit Formen und Deutungsmöglichkeiten, ist daher im Hinblick auf soziokulturelle Verständigungsprozesse unserer zunehmend heterogenen Gesellschaft eine dringliche und richtungsweisende Aufgabe, um Kommunikation zu optimieren und interkulturelles Verständnis zu befördern, gesellschaftliche Entwicklungen zu erkennen, zu nutzen oder aufzufangen. Die Beiträge in diesem Heft zeigen, auf welch vielfältige Weise Wissenschaft mit Zeichen, ihrer Erforschung, Deutung und Erklärung befasst ist. So beschäftigen sich Potsdamer Sozialwissenschaftler damit, ob Eingabenstatistiken von DDR-Bürgern rückblickend als Vorzeichen der friedlichen Revolution von 1989 gelesen werden können. Kollegen vom Institut für Romanistik wiederum untersuchen, was die amerikanischen Reisetagebücher Alexander von Humboldts auszeichnet, und die Nachwuchsforscher des Graduiertenkollegs „Wicked Problems, Contested Administrations“ nehmen gezielt Probleme in den Blick, bei denen Verwaltungen vor übergroßen Fragezeichen zu stehen scheinen. Dass Wissenschaft dazu beitragen kann, Zeichen zu setzen, will ein Projekt zur Förderung nachhaltigen Konsums beweisen. Eine Initiative von Historikern, die brandenburgische Städte bei der Vermittlung der Geschichte der Reformation unterstützen zeigt, dass zwischen Wissenschaft auf der einen und Zeichen und Wundern auf der anderen Seite keine unüberbrückbare Kluft besteht.

Genetische Differenzierung führte im Laufe von Jahrmillionen zur Ausbildung einer schier unglaublichen Artenvielfalt. Die Evolution hat viele Wege beschritten. Sie hat zu großartiger natürlicher Biodiversität geführt – zu Organismen, die an sehr unterschiedliche Umwelten angepasst sind und zum Teil eine ulkige Gestalt haben oder ein merkwürdiges Verhalten zeigen. Aber auch die von Menschenhand gemachte Biodiversität ist überwältigend – man denke nur an die 10.000 verschiedenen Rosensorten, die uns entzücken, oder die Myriaden unterschiedlicher Weizen-, Gerste- oder Maisvarianten; Pflanzen, die allesamt früher einmal einfache Gräser waren, uns heute aber ernähren. Wir Menschen schaffen eine eigene Biodiversität, eine, die die Natur selbst nicht kennt. Und wir „fahren“ gut damit. Dank der Genomforschung können wir heute die gesamte Erbinformation von Organismen in wenigen Stunden bis Tagen aus- lesen. Sehr viel länger dauert es aber, die zahlreichen Abschnitte eines Genoms funktionell zu kartieren. Die Wissenschaftler bedienen sich dazu vielfältiger Methoden: Dabei gehört es heute weltweit zum Standardrepertoire, Gene gezielt zu inaktivieren oder zu aktivieren, ihren Code zu modifizieren oder Erbinformationen zwischen Organismen auszutauschen. Dennoch sind die Wege, die zur Erkenntnis führen, oft verschlungen. Nicht selten müssen ausgeklügelte experimentelle Ansätze gewählt werden, um neue Einsichten in biologische Prozesse zu gewinnen. Mit den Methoden der Genomforschung können wir nicht nur das erkunden, was sich in der Natur „da draußen“ findet. Wir können auch fragen: „Wie verhält sich ein Lebewesen, beispielsweise ein Moos, eigentlich, wenn wir es zur International Space Station (ISS) schicken? Und können wir daraus Kenntnisse gewinnen über die Anpassungsstrategien von Lebewesen an harsche Umweltbedingungen oder gar für eine spätere Besiedlung des Mondes oder des Mars´?“ Oder können wir mithilfe der synthetischen Biologie Mikroorganismen präzise, quasi am Reißbrett geplant, so verändern, dass neue Optionen für die Behandlung von Krankheiten und für die Herstellung innovativer biobasierter Produkte entstehen? Die Antwort auf beide Fragen lautet eindeutig: Ja! (Wenngleich ein Umzug auf andere Planeten derzeit natürlich nicht vornan steht.). Landnutzung durch den Menschen bestimmt die Biodiversität. Andererseits tragen Organismen zur landschaftlichen Formenbildung bei und beeinflussen über kurz oder lang die Zusammensetzung unserer Atmosphäre. Auch hier gibt es spannende Fragen, mit denen sich die Forschung beschäftigt. Um neue Erkenntnisse zu gewinnen, müssen Forscher immer wieder neue Wege einschlagen. Oft kreuzen sich auch Pfade. So war es beispielsweise vor wenigen Jahren noch kaum absehbar, wir stark die ökologische Forschung beispielsweise von den schnellen DNA-Sequenziermethoden profitieren würde, und die Genomforscher unter uns konnten kaum erahnen, wie die gleichen Techniken uns neue Möglichkeiten an die Hand geben sollten, die hochkomplexe Regulation in Zellen zu untersuchen und für die Optimierung biotechnologischer Prozesse zu nutzen.

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

Post mortem decay, resulting in fragmented and chemically modified DNA, is a key obstacle in ancient DNA analyses. In the absence of reliable methods to determine the presence of endogenous DNA in sub-fossil samples, temporal and spatial surveys of DNA survival on a regional scale may help to estimate the potential of faunal remains from a given time period and region. We therefore investigated PCR amplification success, PCR performance and post mortem damage in c. 47,000 to c. 12,000-year-old horse remains from 14 Palaeolithic sites along the Swiss Jura Mountains in relation to depositional context, tissue type, storage time and age, potentially influencing DNA preservation. The targeted 75 base pair mitochondrial DNA fragment could be amplified solely from equid remains from caves and not from any of the open dry and (temporary) wetland sites. Whether teeth are better than bones cannot be ultimately decided; however, both storage time after excavation and age significantly affect PCR amplification and performance, albeit not in a linear way. This is best explained by the—inevitable—heterogeneity of the data set. The extent of post mortem damage is not related to any of the potential impact factors. The results encourage comprehensive investigations of Palaeolithic cave sites, even from temperate regions.

Axel T1 - Microbial abundance in lacustrine sediments BT - a case study from Lake Van, Turkey T2 - Postprints der Universität Potsdam Mathematisch-Naturwissenschaftliche Reihe N2 - The ICDP "PaleoVan" drilling campaign at Lake Van, Turkey, provided a long (> 100 m) record of lacustrine subsurface sedimentary microbial cell abundance. After the ICDP campaign at Potrok Aike, Argentina, this is only the second time deep lacustrine cell counts have been documented. Two sites were cored and revealed a strikingly similar cell distribution despite differences in organic matter content and microbial activity. Although shifted towards higher values, cell counts from Lake Potrok Aike, Argentina, reveal very similar distribution patterns with depth. The lacustrine cell count data are significantly different from published marine records; the most probable cause is differences in sedimentary organic matter composition with marine sediments containing a higher fraction of labile organic matter. Previous studies showed that microbial activity and abundance increase centimetres to metres around geologic interfaces. The finely laminated Lake Van sediment allowed studying this phenomenon on the microscale. We sampled at the scale of individual laminae, and in some depth intervals, we found large differences in microbial abundance between the different laminae. This small-scale heterogeneity is normally overlooked due to much larger sampling intervals that integrate over several centimetres. However, not all laminated intervals exhibit such large differences in microbial abundance, and some non-laminated horizons show large variability on the millimetre scale as well. The reasons for such contrasting observations remain elusive, but indicate that heterogeneity of microbial abundance in subsurface sediments has not been taken into account sufficiently. These findings have implications not just for microbiological studies but for geochemistry as well, as the large differences in microbial abundance clearly show that there are distinct microhabitats that deviate considerably from the surrounding layers.

This presumed lack of authenticity has obviously prompted modern scholarship for a long time to be oblivious to this contemporary and exclusive source on the events, preferring well-known and reliable sources such as Leonard of Chios and Isidore of Kiev. However, since frater Simon’s letter has survived in two different versions and ten manuscripts from the 15th century, it is clearly more than a marginal note. Rather is it a remarkable contribution to the literary treatment of the Turkish threat and timeless moral instruction.With his portrayal of the pagan Mehmed II as a just ruler, the recurring moral instructions and the lack of a call to arms.

Versäumte es die Reichsregierung unter Kanzler Heinrich Brüning aus politisch- revisionistischem Kalkül heraus bewusst, diese Angebote auszuloten? War die eiserne Sparpolitik der ersten beiden Präsidialkabinette also nicht die alternativlose Konsequenz ökonomischer Zwänge, sondern die logische Folge davon unabhängiger außen- und gesellschaftspolitischer Prämissen?

N2 - In spite of indicative archival material and in clear opposition to the current state of research, the highly influential economic historian Knut Borchardt claims in 2015’s spring issue of the VfZ that there never were any serious French loan offers to Germany in 1930. By doing so, Borchardt adheres to his by now rather traditional interpretation of Heinrich Brüning’s chancellorship as a period of “predicaments” in which the policy of austerity was ultimately the only possible alternative. Yet it is, most notably, Brüning’s personal statements in contemporary sources and in his later comments which do offer quite different interpretations. Finally, Borchardt has to accept that other historians are willing to take those accounts seriously.

Die Bundesregierung unter Kanzler Helmut Schmidt und Außenminister Hans-Dietrich Genscher befand sich in einer Zwickmühle: Einerseits war der Iran ein wichtiger Erdöllieferant und Handelspartner, andererseits verstörte die Gewalt gegen politische Gegner und Vertreter der westlichen Staatengemeinschaft, die in der Besetzung der amerikanischen Botschaft in Teheran gipfelte. Frank Bösch zeigt auf der Basis neuer Quellen, wie die Bundesregierung auf die islamische Revolution reagierte, zwischen interessengeleitetem Pragmatismus und außenpolitisch gebotener Bündnistreue zu den USA lavierte und so hinter den Kulissen als Vermittler zwischen Teheran und Washington fungieren konnte. N2 - Even contemporaries saw the Iranian Revolution of 1979 as an important caesura which increased fears of radical Islamic violence worldwide. As the Federal Republic had maintained very close relations to Iran during the time of the Shah, a severance of relations with the Islamic Republic in similar fashion as the USA was to be expected. On the contrary this article, based on archival sources, shows that West German politicians and businesses engaged with the new clerical leadership and in so doing were relatively unaffected by the public human rights discourse despite mass executions. The previous economic and cultural connections to Iran facilitated the setting up of political bridges and resulted in the role of the Federal Republic as a pragmatic intermediary, also towards the USA. As hitherto classified files reveal in detail, the Germans were also able to play a key role during the secret negotiations regarding the hostage crisis in the American embassy in Tehran. Even though the protests against human rights violations increased in the autumn of 1981, politicians and businessmen, in principal, continued with these pragmatically maintained relations.

N2 - Natural evolution has created biopolymers on the basis of amino acids and nucleotides showing high chemical selectivity and catalytic power. Molecular recognition by antibodies and catalytic conversion of the substrate molecules by enzymes take place in so called paratopes or catalytic centres of the macromolecule which comprise typically 10-15 amino acids. The concerted interaction between the reaction partners result in affinities down to nanomolar concentrations for the antigen binding and approaches one million turnovers per second in enzyme-catalyzed reactions. Nucleic acids bind complimentary single stranded nucleic acids by base pairing (hybridisation) with nanomolar affinities but also interact highly specific with proteins, e.g. transcription factors, and lowmolecular weight molecules and even with ions. Biomimetic binders and catalysts have been generated using “evolution in the test tube” of non-natural nucleotides or total chemical synthesis of (molecularly imprinted) polymers in order to substitute the biological pendants in bioanalysis.

Proposed mechanisms on how the gut microbiota could contribute to obesity and metabolic diseases include: (1) improved energy extraction from diet by the conversion of dietary fibre to SCFA; (2) increased intestinal permeability for bacterial lipopolysaccharides (LPS) in response to the consumption of high-fat diets resulting in an elevated systemic LPS level and low-grade inflammation. Animal studies indicate differences in the physiologic effects of fermentable and non-fermentable dietary fibres as well as differences in long-and short-term effects of fermentable dietary fibre. The human intestinal microbiome is enriched in genes involved in the degradation of indigestible polysaccharides. The extent to which dietary fibres are fermented and in which molar ratio SCFA are formed depends on their physicochemical properties and on the individual microbiome. Acetate and propionate play an important role in lipid and glucose metabolism. Acetate serves as a substrate for de novo lipogenesis in liver, whereas propionate can be utilised for gluconeogenesis. The conversion of fermentable dietary fibre to SCFA provides additional energy to the host which could promote obesity. However, epidemiologic studies indicate that diets rich in fibre rather prevent than promote obesity development. This may be due to the fact that SCFA are also ligands of free fatty acid receptors (FFAR). Activation of FFAR leads to an increased expression and secretion of enteroendocrine hormones such as glucagon-like-peptide 1 or peptide YY which cause satiety. In conclusion, the role of SCFA in host energy balance needs to be re-evaluated.

Little is known about word-based morphosyntax in late bilinguals and of how morphosyntax is represented and processed in a nonnative speaker's lexicon. To address these questions, we report results from two behavioral experiments investigating stem variants of strong verbs in German (which encode features such as tense, person, and number) in groups of advanced adult learners as well as native speakers of German. Although the late bilinguals were highly proficient in German, the results of a lexical priming experiment revealed clear native-nonnative differences. We argue that lexical representation and processing relies less on morphosyntactic information in a nonnative than in a native language.

Based on a corpus of emails and postings to media websites, I analyse central topoi in this debate and an underlying narrative on language and identity. Central elements of this narrative are claims of cultural elevation and cultural unity for an idealised standard language High German', a view of German dialects as part of a national folk culture, and the construction of an exclusive in-group of German' speakers who own this language and its dialects. The narrative provides a potent conceptual frame for the Othering of Kiezdeutsch and its speakers, and for the projection of social and sometimes racist deliminations onto the linguistic plane.

Several studies indicate that IAT scores can be faked on instruction. But fully or semi-instructed research scenarios might not properly reflect what happens in more realistic situations, when participants secretly decide to try faking the test. The present study is the first to investigate IAT faking when there is only an implicit incentive to do so. Sixty-five athletes (22.83 years +/- 2.45; 25 women) were randomly assigned to an incentive-to-fake condition or a control condition. Participants in the incentive-to-fake condition were manipulated to believe that athletes with lenient doping attitudes would be referred to a tedious 45-minute anti-doping program. Attitudes were measured with the pictorial doping brief IAT (BIAT) and with the Performance Enhancement Attitude Scale (PEAS). A one-way MANOVA revealed significant differences between conditions after the manipulation in PEAS scores, but not in the doping BIAT. In the light of our hypothesis this suggests that participants successfully faked an exceedingly negative attitude to doping when completing the PEAS, but were unsuccessful in doing so on the reaction time-based test. This study assessed BIAT faking in a setting that aimed to resemble a situation in which participants want to hide their attempts to cheat. The two measures of attitude were differentially affected by the implicit incentive. Our findings provide evidence that the pictorial doping BIAT is relatively robust against spontaneous and naive faking attempts. (B) IATs might be less prone to faking than implied by previous studies.

T1 - Coexistence of morphologically similar bats (Vespertilionidae) on Madagascar BT - stable isotopes reveal fine-grained niche differentiation among cryptic species T2 - Postprints der Universität Potsdam : Mathematisch-Naturwissenschaftliche Reihe N2 - Based on niche theory, closely related and morphologically similar species are not predicted to coexist due to overlap in resource and habitat use. Local assemblages of bats often contain cryptic taxa, which co-occur despite notable similarities in morphology and ecology. We measured in two different habitat types on Madagascar levels of stable carbon and nitrogen isotopes in hair (n = 103) and faeces (n = 57) of cryptic Vespertilionidae taxa to indirectly examine whether fine-grained trophic niche differentiation explains their coexistence. In the dry deciduous forest (Kirindy), six sympatric species ranged over 6.0% in delta N-15, i.e. two trophic levels, and 4.2% in delta C-13 with a community mean of 11.3% in delta N-15 and - 21.0% in delta C-13. In the mesic forest (Antsahabe), three sympatric species ranged over one trophic level (delta N-15: 2.4%, delta C-13: 1.0%) with a community mean of 8.0% delta N-15 and - 21.7% in delta C-13. Multivariate analyses and residual permutation of Euclidian distances in delta C-13- delta N-15 bi-plots revealed in both communities distinct stable isotope signatures and species separation for the hair samples among coexisting Vespertilionidae. Intraspecific variation in faecal and hair stable isotopes did not indicate that seasonal migration might relax competition and thereby facilitate the local co-occurrence of sympatric taxa.

T1 - aspeed BT - solver scheduling via answer set programming T2 - Postprints der Universität Potsdam : Mathematisch-Naturwissenschaftliche Reihe N2 - Although Boolean Constraint Technology has made tremendous progress over the last decade, the efficacy of state-of-the-art solvers is known to vary considerably across different types of problem instances, and is known to depend strongly on algorithm parameters. This problem was addressed by means of a simple, yet effective approach using handmade, uniform, and unordered schedules of multiple solvers in ppfolio, which showed very impressive performance in the 2011 Satisfiability Testing (SAT) Competition. Inspired by this, we take advantage of the modeling and solving capacities of Answer Set Programming (ASP) to automatically determine more refined, that is, nonuniform and ordered solver schedules from the existing benchmarking data. We begin by formulating the determination of such schedules as multi-criteria optimization problems and provide corresponding ASP encodings. The resulting encodings are easily customizable for different settings, and the computation of optimum schedules can mostly be done in the blink of an eye, even when dealing with large runtime data sets stemming from many solvers on hundreds to thousands of instances. Also, the fact that our approach can be customized easily enabled us to swiftly adapt it to generate parallel schedules for multi-processor machines.

However, long-term studies in larger clinical settings are lacking, and little is known about moderating effects of patient and service characteristics. Methods: Data from 12,910 outpatients with dementia (mean age 79.2 years; SD = 7.6 years) treated between January 2003 and December 2013 in Germany were included. Continuous treatment was analysed using Kaplan-Meier curves and log-rank tests. In addition, multivariate Cox regression models were fitted with continuous treatment as dependent variable and the predictors antidementia agent, age, gender, medical comorbidities, physician specialty, and health insurance status. Results: After one year of follow-up, nearly 60% of patients continued drug treatment. Donezepil (HR: 0.88; 95% CI: 0.82-0.95) and memantine (HR: 0.85; 0.79-0.91) patients were less likely to be discontinued treatment as compared to rivastigmine users. Patients were less likely to be discontinued if they were treated by specialist physicians as compared to general practitioners (HR: 0.44; 0.41-0.48). Younger male patients and patients who had private health insurance had a lower discontinuation risk. Regarding comorbidity, patients were more likely to be continuously treated with the index substance if a diagnosis of heart failure or hypertension had been diagnosed at baseline. Conclusions: Our results imply that besides type of antidementia agent, involvement of a specialist in the complex process of prescribing antidementia drugs can provide meaningful benefits to patients, in terms of more disease-specific and continuous treatment.

A1 - Herzschuh, Ulrike T1 - The evolution of sub-monsoon systems in the Afro-Asian monsoon region during the Holocene BT - comparison of different transient climate model simulations T2 - Postprints der Universität Potsdam : Mathematisch-Naturwissenschaftliche Reihe N2 - The recently proposed global monsoon hypothesis interprets monsoon systems as part of one global-scale atmospheric overturning circulation, implying a connection between the regional monsoon systems and an in-phase behaviour of all northern hemispheric monsoons on annual timescales (Trenberth et al., 2000). Whether this concept can be applied to past climates and variability on longer timescales is still under debate, because the monsoon systems exhibit different regional characteristics such as different seasonality (i. e. onset, peak and withdrawal). To investigate the interconnection of different monsoon systems during the pre-industrial Holocene, five transient global climate model simulations have been analysed with respect to the rainfall trend and variability in different sub-domains of the Afro-Asian monsoon region. Our analysis suggests that on millennial timescales with varying orbital forcing, the monsoons do not behave as a tightly connected global system. According to the models, the Indian and North African monsoons are coupled, showing similar rainfall trend and moderate correlation in centennial rainfall variability in all models. The East Asian monsoon changes independently during the Holocene. The dissimilarities in the seasonality of the monsoon sub-systems lead to a stronger response of the North African and Indian monsoon systems to the Holocene insolation forcing than of the East Asian monsoon and affect the seasonal distribution of Holocene rainfall variations. Within the Indian and North African monsoon domain, precipitation solely changes during the summer months, showing a decreasing Holocene precipitation trend. In the East Asian monsoon region, the precipitation signal is determined by an increasing precipitation trend during spring and a decreasing precipitation change during summer, partly balancing each other. A synthesis of reconstructions and the model results do not reveal an impact of the different seasonality on the timing of the Holocene rainfall optimum in the different sub-monsoon systems. Rather they indicate locally inhomogeneous rainfall changes and show that single palaeo-records should not be used to characterise the rainfall change and monsoon evolution for entire monsoon sub-systems.

Identifying classes of programs for which the consistency problem is in NP is of interest from the theoretical standpoint and can potentially lead to improvements in the design of answer set programming solvers. One of such classes consists of dual-normal programs, where the number of positive body atoms in proper rules is at most one. Unlike other classes of programs, dual-normal programs have received little attention so far. In this paper we study this class. We relate dual-normal programs to propositional theories and to normal programs by presenting several inter-translations. With the translation from dual-normal to normal programs at hand, we introduce the novel class of body-cycle free programs, which are in many respects dual to head-cycle free programs. We establish the expressive power of dual-normal programs in terms of SE- and UE-models, and compare them to normal programs. We also discuss the complexity of deciding whether dual-normal programs are strongly and uniformly equivalent.
