In plants, MADS-domain transcription factors act as master regulators of developmental switches and organ specification. However, the mechanisms by which these factors dynamically regulate the expression of their target genes at different developmental stages are still poorly understood. Results: We characterized the relationship of chromatin accessibility, gene expression, and DNA binding of two MADS-domain proteins at different stages of Arabidopsis flower development. Dynamic changes in APETALA1 and SEPALLATA3 DNA binding correlated with changes in gene expression, and many of the target genes could be associated with the developmental stage in which they are transcriptionally controlled. We also observe dynamic changes in chromatin accessibility during flower development. Remarkably, DNA binding of APETALA1 and SEPALLATA3 is largely independent of the accessibility status of their binding regions and it can precede increases in DNA accessibility. These results suggest that APETALA1 and SEPALLATA3 may modulate chromatin accessibility, thereby facilitating access of other transcriptional regulators to their target genes. Conclusions: Our findings indicate that different homeotic factors regulate partly overlapping, yet also distinctive sets of target genes in a partly stage-specific fashion. By combining the information from DNA-binding and gene expression data, we are able to propose models of stage-specific regulatory interactions, thereby addressing dynamics of regulatory networks throughout flower development. Furthermore, MADS-domain TFs may regulate gene expression by alternative strategies, one of which is modulation of chromatin accessibility.}, language = {en} } @article{Mackert2014, author = {Mackert, J{\"u}rgen}, title = {The secret society and the social dynamics of terrorist behavior}, series = {Revue de Synth{\`e}se}, volume = {135}, journal = {Revue de Synth{\`e}se}, publisher = {Brill}, address = {Leiden}, issn = {1955-2343}, doi = {10.1007/s11873-014-0261-z}, pages = {331 -- 359}, year = {2014}, abstract = {The article argues that individualist accounts cannot adequately explain the social dynamics of terrorist behavior as they turn analyses of terrorism into analyses of terrorists.

Amongst birds, a single order, Dinornithiformes, comprising the extinct wingless moa of New Zealand, are unique in having no skeletal evidence of forelimb-like structures. Results To determine the sequence of tbx5 in moa, we used a range of PCR-based techniques on ancient DNA to retrieve all nine tbx5 exons and splice sites from the giant moa, Dinornis. Moa Tbx5 is identical to chicken Tbx5 in being able to activate the downstream promotors of fgf10 and ANF. In addition we show that missexpression of moa tbx5 in the hindlimb of chicken embryos results in the formation of forelimb features, suggesting that Tbx5 was fully functional in wingless moa. An alternatively spliced exon 1 for tbx5 that is expressed specifically in the forelimb region was shown to be almost identical between moa and ostrich, suggesting that, as well as being fully functional, tbx5 is likely to have been expressed normally in moa since divergence from their flighted ancestors, approximately 60 mya. Conclusions The results suggests that, as in mice, moa tbx5 is necessary for the induction of forelimbs, but is not sufficient for their outgrowth. Moa Tbx5 may have played an important role in the development of moa's remnant forelimb girdle, and may be required for the formation of this structure.

We compared anticipation of reward between major psychiatric disorders, and investigated whether reward anticipation is impaired in several mental disorders and whether there is a common psychopathological correlate (negative mood) of such an impairment.

During reward anticipation, we observed significant group differences in ventral striatal (VS) activation: patients with schizophrenia, alcohol dependence, and major depression showed significantly less ventral striatal activation compared to healthy controls. Depressive symptoms correlated with dysfunction in reward anticipation regardless of diagnostic entity. There was no significant correlation between anxiety symptoms and VS functional activation. Our findings demonstrate a neurobiological dysfunction related to reward prediction that transcended disorder categories and was related to measures of depressed mood.

However the polymerase chain reaction remains laboratory-based and has to be conducted by trained personnel. Furthermore, the power dependency for the thermocycling process and the costly equipment necessary for the read-out are difficult to cover in resource-limited settings. This study aims to develop and evaluate a combination of isothermal nucleic acid amplification and simple lateral flow dipstick detection of the malaria parasite for point-of-care testing. Methods A specific fragment of the 18S rRNA gene of P. falciparum was amplified in 10 min at a constant 38°C using the isothermal recombinase polymerase amplification (RPA) method. With a unique probe system added to the reaction solution, the amplification product can be visualized on a simple lateral flow strip without further labelling. The combination of these methods was tested for sensitivity and specificity with various Plasmodium and other protozoa/bacterial strains, as well as with human DNA. Additional investigations were conducted to analyse the temperature optimum, reaction speed and robustness of this assay. Results The lateral flow RPA (LF-RPA) assay exhibited a high sensitivity and specificity. Experiments confirmed a detection limit as low as 100 fg of genomic P. falciparum DNA, corresponding to a sensitivity of approximately four parasites per reaction. All investigated P. falciparum strains (n = 77) were positively tested while all of the total 11 non-Plasmodium samples, showed a negative test result. The enzymatic reaction can be conducted under a broad range of conditions from 30-45°C with high inhibitory concentration of known PCR inhibitors. A time to result of 15 min from start of the reaction to read-out was determined. Conclusions Combining the isothermal RPA and the lateral flow detection is an approach to improve molecular diagnostic for P. falciparum in resource-limited settings. The system requires none or only little instrumentation for the nucleic acid amplification reaction and the read-out is possible with the naked eye. Showing the same sensitivity and specificity as comparable diagnostic methods but simultaneously increasing reaction speed and dramatically reducing assay requirements, the method has potential to become a true point-of-care test for the malaria parasite.}, language = {en} } @misc{ThiekenCammererDobleretal.2014, author = {Thieken, Annegret and Cammerer, Holger and Dobler, Christian and Lammel, Johannes and Sch{\"o}berl, Fritz}, title = {Estimating changes in flood risks and benefits of non-structural adaptation strategies}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, number = {910}, issn = {1866-8372}, doi = {10.25932/publishup-43228}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-432282}, pages = {36}, year = {2014}, abstract = {Flood damage has increased significantly and is expected to rise further in many parts of the world. For assessing potential changes in flood risk, this paper presents an integrated model chain quantifying flood hazards and losses while considering climate and land use changes. In the case study region, risk estimates for the present and the near future illustrate that changes in flood risk by 2030 are relatively low compared to historic periods. While the impact of climate change on the flood hazard and risk by 2030 is slight or negligible, strong urbanisation associated with economic growth contributes to a remarkable increase in flood risk. Therefore, it is recommended to frequently consider land use scenarios and economic developments when assessing future flood risks. Further, an adapted and sustainable risk management is necessary to encounter rising flood losses, in which non-structural measures are becoming more and more important. The case study demonstrates that adaptation by non-structural measures such as stricter land use regulations or enhancement of private precaution is capable of reducing flood risk by around 30 \%. Ignoring flood risks, in contrast, always leads to further increasing losses-with our assumptions by 17 \%. These findings underline that private precaution and land use regulation could be taken into account as low cost adaptation strategies to global climate change in many flood prone areas. Since such measures reduce flood risk regardless of climate or land use changes, they can also be recommended as no-regret measures.}, language = {en} } @misc{BoeckmannOsterloh2014, author = {B{\"o}ckmann, Christine and Osterloh, Lukas}, title = {Runge-Kutta type regularization method for inversion of spheroidal particle distribution from limited optical data}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, number = {907}, issn = {1866-8372}, doi = {10.25932/publishup-44120}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-441200}, pages = {150 -- 165}, year = {2014}, abstract = {The Runge-Kutta type regularization method was recently proposed as a potent tool for the iterative solution of nonlinear ill-posed problems.

However, stress drop calculations based on fault slip can be significantly biased, particularly due to subjectively determined smoothing conditions in the traditional least-square slip inversion. In this study, we introduce a mechanically constrained Bayesian approach to simultaneously invert for fault slip and stress drop based on geodetic measurements. A Gaussian distribution for stress drop is implemented in the inversion as a prior. We have done several synthetic tests to evaluate the stability and reliability of the inversion approach, considering different fault discretization, fault geometries, utilized datasets, and variability of the slip direction, respectively. We finally apply the approach to the 2010 M8.8 Maule earthquake and invert for the coseismic slip and stress drop simultaneously. Two fault geometries from the literature are tested. Our results indicate that the derived slip models based on both fault geometries are similar, showing major slip north of the hypocenter and relatively weak slip in the south, as indicated in the slip models of other studies. The derived mean stress drop is 5-6 MPa, which is close to the stress drop of similar to 7 MPa that was independently determined according to force balance in this region Luttrell et al.

Here, we examine the interaction between adaptive learning signals (using a well-characterized probabilistic reversal learning task in combination with fMRI) and SLES on fluid IQ measures. We find that the correlation between ventral striatal BOLD PE and fluid IQ, which we have previously reported, is quantitatively modulated by the amount of reported SLES. Thus, after experiencing adversity, basic neuronal learning signatures appear to align more closely with a general measure of flexible learning (fluid IQ), a finding complementing studies on the effects of acute stress on learning.

At the same time Arabidopsis is a model plant with high frequencies of gene duplications. Here, we have conducted a systematic analysis of the Arabidopsis kinase complement, the kinome, with particular focus on gene duplication events. We matched Arabidopsis proteins to a Hidden-Markov Model of eukaryotic kinases and computed a phylogeny of 942 Arabidopsis protein kinase domains and mapped their origin by gene duplication. Results The phylogeny showed two major clades of receptor kinases and soluble kinases, each of which was divided into functional subclades. Based on this phylogeny, association of yet uncharacterized kinases to families was possible which extended functional annotation of unknowns. Classification of gene duplications within these protein kinases revealed that representatives of cytosolic subfamilies showed a tendency to maintain segmentally duplicated genes, while some subfamilies of the receptor kinases were enriched for tandem duplicates. Although functional diversification is observed throughout most subfamilies, some instances of functional conservation among genes transposed from the same ancestor were observed. In general, a significant enrichment of essential genes was found among genes encoding for protein kinases. Conclusions The inferred phylogeny allowed classification and annotation of yet uncharacterized kinases.

Even today, 1584 years after Augustine, time still appears mysterious. Treatises about the essence of time fill whole libraries - and this magazine. However, questions of essence are alien to modern sciences. Time is - at least in physics - unproblematic: "Time is defined so that motion looks simple", briefly and prosaically phrased, waves goodbye to Augustine's riddle and to the Newtonian concept of absolute time, whose mathematical flow can only be approximately recorded with earthly instruments anyway. In our everyday language and even in science we still speak of the flow of time but time has not been a natural condition for quite a while now. It is rather a conventional order parameter for change and movement. Processes are arranged by using a class of processes as a counting system in order to compare other processes and to organize them with the help of the temporary categories "before", "during", and "after". During Galileo's time one's own pulse was seen as the time standard for the flight of cannon balls. More sophisticated examination methods later made this seem too impractical. The distance-time diagrams of free-flying cannon balls turned out to be rather imprecise, difficult to replicate, and in no way "simple". Nowadays, we use cesium atoms. A process is said to take one second when a caesium-133 atom completes 9,192,631,770 periods of the radiation corresponding to the transition between two hyperfine levels of the ground state. A meter is the length of the path travelled by light in a vacuum in exactly 1/299,792,458 of a second. Fortunately, these data are hard-coded in the Global Positioning System GPS so users do not have to reenter them each time they want to know where they are. In the future, however, they might have to download an app because the time standard has been replaced by sophisticated transitions to ytterbium. The conventional character of the time concept should not tempt us to believe that everything is somehow relative and, as a result, arbitrary. The relation of one's own pulse to an atomic clock is absolute and as real as the relation of an hourglass to the path of the sun. The exact sciences are relational sciences. They are not about the thing-initself as Newton and Kant dreamt, but rather about relations as Leibniz and, later, Mach pointed out. It is not surprising that the physical time standard turned out to be rather impractical for other scientists. The psychology of time perception tells us - and you will all agree - that the perceived age is quite different from the physical age. The older we get the shorter the years seem. If we simply assume that perceived duration is inversely related to physical age and that a 20-year old also perceives a physical year as a psychological one, we come to the surprising discovery that at 90 years we are 90 years old. With an assumed life expectancy of 90 years, 67\% (or 82\%) of your felt lifetime is behind you at the age of 20 (or 40) physical years. Before we start to wallow in melancholy in the face of the "relativity of time", let me again quote Augustine. "But at any rate this much I dare affirm I know: that if nothing passed there would be no past time; if nothing were approaching, there would be no future time; if nothing were, there would be no present time." Well, - or as Bob Dylan sings "The times they are a-changin". I wish you an exciting time reading this issue.

Children enjoy listening to a story but when my children were about four years old they started asking whether the story really happened or was just invented. Likewise, only on a higher level, our academic curiosity is fuelled by our interest in knowing what is real. When we analyze poetic texts or dreams we are trying to distinguish between the facts (e.g. neurological ones or linguistic structures) and merely assumed influences. Ideally we can present results that were logically understood by others and that we can repeat empirically. But in most cases this is not possible. We cannot read every book and cannot look through every microscope, not even within our own discipline. In the world we live in we depend on trusting the information of others, like how to get to the train station or what the weather is like in Ulaanbataar. This is why we are used to believing others, our friends or the news anchors. This is not a childish behavior but a necessity. Of course, it is risky because they could all be lying to us, like in a Truman Show situation. The only time we are able to know that we are in reality is when we transcend our selfconsciousness and when we accept two propositions: first, that we are not only objects but also subjects in the consciousness of others and second that our dialogic relations are again observed by a third party that is not part of this intersubjective world. For religious people this is "belief" - belief as the assumption that all human relations only become real, serious and beyond any doubt if they know they are under the eyes of God. Only before Him something is in itself and not only "for me" or "among us". That is why biblical language distinguishes between three forms of belief: the relationship with the world of things ("to believe that"), the relationship to the world of subjects ("to believe somebody") and the assumption of a subjective supernatural reality ("to believe in" or "faith"). From an academic point of view belief is a holistic hypothesis. Belief is not the opposite of knowledge but it is the attempt to save reality from doubt by comprehending the fragile empirical world as an expression of a stable transcendent world. When I talk to students they often ask not only about what I know but what I believe. As a professor for Religious Studies and a believing Catholic I am caught in the middle. On the one hand, it is my duty as a professor to doubt everything, i.e. to attribute each religious text to its historical context and sociological functions. On the other hand, I, as a Christian, consider certain religious documents, in my case the Bible, an interpretable but nevertheless irreversible, revealed text about the origin of reality. On weekdays the New Testament is a collection of ancient writings among many others, on Sundays it is the revelation. You can make a clear distinction between these two perspectives but it is difficult to decide whether doubt or belief is more real. This issue of "Portal Wissen" explores this dual relationship of belief. What is the attitude of science towards belief - is it a religious one? Where does science bring things to light that we can hardly believe or that make us believe (again)? What happens if research clears up erroneous assumptions or myths? Is science able to investigate things that are convincing but inexplicable? How can it maintain its credibility and develop even so? These questions appear again and again in the contributions of this "Portal Wissen". They form a manifold, exciting and surprising picture of the research projects and academics at the University of Potsdam. Believe me, it will be an enjoyable read.

Auch heute, 1584 Jahre nach Augustinus, erscheint 'Zeit' immer noch r{\"a}tselhaft. Abhandlungen {\"u}ber das Wesen der Zeit f{\"u}llen Bibliotheken. Oder eben dieses Heft. Wesensfragen sind den modernen Wissenschaften allerdings fremd. Zeit ist - zumindest in der Physik - unproblematisch. „Time is defined so that Motion looks simple" erk{\"a}rt man kurz und trocken, und verabschiedet sich damit vom Augustinischen R{\"a}tsel oder der Newtonschen Vorstellung einer absoluten Zeit, deren mathematischen Fluss man durch irdische Instrumente eh immer nur n{\"a}herungsweise erfassen kann. In der Alltagssprache, selbst in den Wissenschaften, reden wir zwar weiterhin vom Fluss der Zeit, aber Zeit ist schon lange keine nat{\"u}rliche Gegebenheit mehr. Zeit ist vielmehr ein konventioneller Ordnungsparameter f{\"u}r {\"A}nderung und Bewegung. Geordnet werden Prozesse, indem eine Klasse von Prozessen als Z{\"a}hlsystem dient, um andere Prozesse mit ihnen zu vergleichen und anhand der tempor{\"a}ren Kategorien „vorher", „w{\"a}hrend" und „nachher" anzuordnen. Zu Galileis Zeiten galt der eigene Pulsschlag als Zeitstandard f{\"u}r den Flug von Kanonenkugeln. Mit zunehmender Verfeinerung der Untersuchungsmethoden erschien das zu unpraktisch: Die Weg-Zeit-Diagramme frei fliegender Kanonenkugeln erweisen sich in diesem Standard ziemlich verwackelt, schlecht reproduzierbar, und keineswegs „simpel". Heutzutage greift man zu C{\"a}sium-Atomen. Demnach dauert ein Prozess eine Sekunde, wenn ein 133Cs-Atom genau 9 192 631 770 Schwingungen zwischen zwei sogenannten Hyperfeinzust{\"a}nden des Grundzustands vollf{\"u}hrt hat. Und ein Meter ist die Entfernung, die Licht im Vakuum in exakt 1/299 792 458 Sekunden zur{\"u}cklegt. Gl{\"u}cklicherweise sind diese Daten im General Positioning System GPS hart kodiert, so dass der Nutzer sie nicht jedes Mal aufs Neue eingeben muss, wenn er wissen will, wo er ist. Aber schon morgen muss er sich vielleicht ein Applet runterladen, weil der Zeitstandard durch raffinierte {\"U}berg{\"a}nge in Ytterbium ersetzt wurde. Der konventionelle Charakter des Zeitbegriffs sollte nicht dazu verf{\"u}hren zu glauben, alles sei irgendwie relativ und daher willk{\"u}rlich. Die Beziehung eines Pulsschlags zu einer Atomuhr ist absolut, und genauso real, wie die Beziehung einer Sanduhr zum Lauf der Sonne. Die exakten Wissenschaften sind Beziehungswissenschaften. Sie handeln nicht vom Ding an sich, was Newton und Kant noch getr{\"a}umt haben, sondern von Beziehungen - worauf schon Leibniz und sp{\"a}ter Mach hingewiesen haben. Kein Wunder, dass sich f{\"u}r andere Wissenschaften der physikalische Zeit-Standard als ziemlich unpraktisch erweist. Der Psychologie der Zeitwahrnehmung entnehmen wir - und jeder wird das best{\"a}tigen k{\"o}nnen - dass das gef{\"u}hlte Alter durchaus verschieden ist vom physikalischen Alter. Je {\"a}lter man ist, desto k{\"u}rzer erscheinen einem die Jahre. Unter der einfachen Annahme, dass die gef{\"u}hlte Dauer umgekehrt proportional zum physikalischen Alter ist, und man als Zwanzigj{\"a}hriger ein physikalisches Jahr auch psychologisch als ein Jahr empfindet, ergibt sich der erstaunliche Befund, dass man mit 90 Jahren 90 Jahre ist. Und - bei einer angenommenen Lebenserwartung von 90 Jahren - mit 20 (bzw. 40) physikalischen Jahren bereits 67 (bzw. 82) Prozent seiner gef{\"u}hlten Lebenszeit hinter sich hat. Bevor man angesichts der „Relativit{\"a}t von Zeit" selbst in Melancholie versinkt, vielleicht die Fortsetzung des Eingangszitats von Augustinus: „Aber zuversichtlich behaupte ich zu wissen, dass es vergangene Zeit nicht g{\"a}be, wenn nichts verginge, und nicht k{\"u}nftige Zeit, wenn nichts herank{\"a}me, und nicht gegenw{\"a}rtige Zeit wenn nichts seiend w{\"a}re."

Kinder lassen sich gern eine Geschichte erz{\"a}hlen, aber sp{\"a}testens mit vier Jahren fragten meine, ob diese Geschichte so passiert sei oder nur erfunden. Das setzt sich fort: Auch unsere wissenschaftliche Neugier wird vom Interesse befeuert herauszufinden, was wirklich ist. Selbst dort, wo wir poetische Texte oder Tr{\"a}ume erforschen, tun wir es in der Absicht, die realen sprachlichen Strukturen bzw. die neurologischen Faktoren von bloß vermuteten zu unterscheiden. Im Idealfall k{\"o}nnen wir Ergebnisse pr{\"a}sentieren, die von anderen logisch nachvollzogen und empirisch wiederholbar sind. Meistens geht das aber nicht. Wir k{\"o}nnen nicht jedes Buch lesen und nicht in jedes Mikroskop schauen, nicht einmal innerhalb der eigenen Disziplin. Wie viel mehr sind wir in der Lebenswelt darauf angewiesen, den Ausf{\"u}hrungen anderer zu vertrauen, wenn wir wissen wollen, wo es zum Bahnhof geht oder ob es in Ulan Bator sch{\"o}n ist. Deshalb haben wir uns daran gew{\"o}hnt, anderen Glauben zu schenken, vom Freund bis zum Tagesschausprecher. Das ist kein kindliches Verhalten, sondern eine Notwendigkeit. Freilich ist das riskant, denn alle anderen k{\"o}nnten uns - wie in der „Truman- Show" - anl{\"u}gen. In der Wirklichkeit wissen wir uns erst dann, wenn wir unser Selbstbewusstsein verlassen und akzeptieren, dass wir erstens nicht nur Objekte, sondern Subjekte im Bewusstsein von anderen sind, und zweitens, dass alle unsere dialogischen Beziehungen noch einmal von einem Dritten betrachtet werden, der nicht Teil dieser Welt ist. F{\"u}r Religi{\"o}se ist das der Glaube. Glaube als Unterstellung, dass alle menschlichen Beziehungen erst dann wirklich, ernst und {\"u}ber Zweifel erhaben sind, wenn sie sich vor den Augen Gottes wissen. Erst vor ihm ist etwas als es selbst und nicht nur „f{\"u}r mich" oder „unter uns". Daher unterscheidet die biblische Sprache drei Formen des Glaubens: die Beziehung zur Ding-Welt („glauben, dass"), die Beziehung zur Subjekt-Welt („jemandem glauben") und die Annahme einer subjekthaften {\"u}berirdischen Wirklichkeit („glauben an"). Wissenschaftstheoretisch gesehen ist Glaube also eine Totalhypothese. Glaube ist nicht das Gegenteil von Wissen, sondern der Versuch, Wirklichkeit vor dem Zweifel zu retten, indem man die fragile empirische Welt als Ausdruck einer stabilen transzendenten Welt begreift. Oft wollen Studierende in Gespr{\"a}chen nicht nur wissen, was ich weiß, sondern, was ich glaube. Als Religionswissenschaftler und gleichzeitig gl{\"a}ubiger Katholik sitze ich zwischen den St{\"u}hlen: Einerseits ist es als Professor meine Aufgabe, alles zu bezweifeln, d.h. jeden religi{\"o}sen Text auf seine historischen Kontexte und soziologischen Funktionen zur{\"u}ckzuf{\"u}hren. Andererseits h{\"a}lt der Christ in mir bestimmte religi{\"o}se Dokumente - in meinem Fall die Bibel - zwar f{\"u}r einen interpretierbaren, aber doch irreversiblen, offenbarten Text, der vom Ursprung der Wirklichkeit handelt. Werktags ist das Neue Testament eine antike Schriftensammlung neben vielen anderen, am Sonntag ist es die Offenbarung. Beides kann klar unterschieden werden, aber es ist schwer zu entscheiden, ob das Zweifeln oder das Glauben wirklicher ist. Das vorliegende Heft geht diesem doppelten Verh{\"a}ltnis zum Glauben nach: Wie steht Wissenschaft zum Glauben - ob religi{\"o}s oder nicht? Wo bringt Wissenschaft Dinge ans Licht, die wir kaum glauben m{\"o}gen oder uns (wieder) glauben lassen? Was passiert, wenn Forschung irrige Annahmen oder Mythen aufkl{\"a}rt? Ist Wissenschaft in der Lage, Dingen auf den Grund zu gehen, die zwar {\"u}berzeugend, aber unerkl{\"a}rbar sind? Wie kann sie selbst glaubw{\"u}rdig bleiben und sich dennoch weiterentwickeln? In den Beitr{\"a}gen dieser „Portal Wissen" scheinen diese Fragen immer wieder auf. Sie bilden ein vielf{\"a}ltiges, spannendes und auch {\"u}berraschendes Bild der Forschungsprojekte und der Wissenschaftler an der Universit{\"a}t Potsdam.

The first is based on linear moveout spectra to find the optimum ground wave velocity including uncertainties from multi-offset data gathers. We used synthetic data to illustrate the principles of the method and to investigate uncertainties in ground wave velocity estimates. To demonstrate the applicability of the approach to real data, we analyzed GPR data sets recorded at field sites in Canada over an annual cycle from Steelman \& Endres [2010]. The results obtained by this efficient and largely automated procedure agree well with the manual achieved results of Steelman \& Endres [2010], derived by a more laborious largely manual analysis strategy. Then we develop a second methodology to global invert reflection traveltimes with a particle swarm optimization approach more precise then conventional spectral NMO-based velocity analysis (e.g., Greaves et al. [1996]). For global optimization, we use particle swarm optimization (PSO; Kennedy \& Eberhart [1995]) in the combination with a fast eikonal solver as forward solver (Sethian [1996]; Fomel [1997a]; Sethian \& Popovici [1999]). This methodology allows us to generate reliability CMP derived models of subsurface velocities and water content including uncertainties. We test this method with synthetic data to study the behavior of the PSO algorithm. Afterward, We use this method to analyze our field data from a well constrained test site in Horstwalde, Germany. The achieved velocity models from field data showed good agreement to borehole logging and direct-push data (Schmelzbach et al. [2011]) at the same site position. For the third method we implement a global optimization approach also based on PSO to invert direct-arrival traveltimes of VRP data to obtain high resolution 1D velocity models including quantitative estimates of uncertainty. Our intensive tests with several traveltime data sets helped to understand the behavior of PSO algorithm for inversion. Integration of the velocity model to VRP reflection imaging and attenuation model improved the potential of VRP surveying. Using field data, we examine this novel analysis strategy for the development of petrophysical models and the linking between GPR borehole and other logging data to surface GPR reflection data.}, language = {de} } @misc{LuckeSzameitatGoerlichetal.2014, author = {Lucke, Ulrike and Szameitat, Ulrike and G{\"o}rlich, Petra and Kampe, Heike and Lux, Nadine and Bomhoff, Hartmut and Rudolph, Pascal and J{\"a}ger, Sophie and Ziemer, Franziska and Friess, Nina and Eckardt, Barbara and Joshi, Jasmin Radha and Huwe, Bj{\"o}rn and Zimmermann, Matthias and S{\"u}tterlin, Sabine}, title = {Portal = Studieren im digitalen Zeitalter: E-Learning in Lehre und Studium}, number = {04/2014}, organization = {Universit{\"a}t Potsdam, Referat f{\"u}r Presse- und {\"O}ffentlichkeitsarbeit}, issn = {1618-6893}, doi = {10.25932/publishup-44061}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-440615}, pages = {42}, year = {2014}, abstract = {Aus dem Inhalt: - Studieren im digitalen Zeitalter: E-Learning in Lehre und Studium - Wie Alice im Wunderland - Moose im All}, language = {de} } @misc{GuentherSuetterlinGoerlichetal.2014, author = {G{\"u}nther, Oliver and S{\"u}tterlin, Sabine and G{\"o}rlich, Petra and Eckardt, Barbara and Mangelsdorf, Birgit and Horn-Conrad, Antje and Br{\"u}ckner, Cornelia and Lux, Nadine and Szameitat, Ulrike and Weller, Nina and Kagels, Melanie and Stahl, Anna-Lena and Temme, Jens and J{\"a}ger, Sophie and Kampe, Heike and Zimmermann, Matthias}, title = {Portal = Auf Humboldts Spuren: Feldforschung an der Universit{\"a}t Potsdam}, number = {02/2014}, organization = {Universit{\"a}t Potsdam, Referat f{\"u}r Presse- und {\"O}ffentlichkeitsarbeit}, issn = {1618-6893}, doi = {10.25932/publishup-44060}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-440607}, pages = {42}, year = {2014}, abstract = {Aus dem Inhalt: - Auf Humboldts Spuren: Feldforschung an der Universit{\"a}t Potsdam - Bevor es knallt - Kein Kommentar!}, language = {de} } @article{Sprinz2014, author = {Sprinz, Detlef F.}, title = {Long-term policy problems: definition, origins, and redponses}, series = {Predicting the Future in Science, Economics, and Politics}, journal = {Predicting the Future in Science, Economics, and Politics}, publisher = {Elgar}, address = {Northampton}, isbn = {978-1-78347-186-7}, pages = {126 -- 143}, year = {2014}, language = {en} } @book{GronauLindemann2014, author = {Gronau, Norbert and Lindemann, Marcus}, title = {Einf{\"u}hrung in das Informationsmanagement}, series = {Skripte zur Wirtschaftsinformatik}, journal = {Skripte zur Wirtschaftsinformatik}, edition = {durchgesehene Aufl.}, publisher = {Gito}, address = {Berlin}, isbn = {978-3-942183-07-9}, pages = {233}, year = {2014}, abstract = {Dieses Buch bietet eine Einf{\"u}hrung in das Informationsmanagement in kommentierter Form.

The isothermal RPA was applied to amplify specific target sequences from the pathogens Neisseria gonorrhoeae, Salmonella enterica and methicillin-resistant Staphylococcus aureus (MRSA) using genomic DNA. Additionally, a positive plasmid control was established as an internal control. The four targets were amplified simultaneously in a quadruplex reaction. The amplicon is labeled during on-chip RPA by reverse oligonucleotide primers coupled to a fluorophore. Both amplification and spatially resolved signal generation take place on immobilized forward primers bount to expoxy-silanized glass surfaces in a pump-driven hybridization chamber. The combination of microarray technology and sensitive isothermal nucleic acid amplification at 38 °C allows for a multiparameter analysis on a rather small area. The on-chip RPA was characterized in terms of reaction time, sensitivity and inhibitory conditions. A successful enzymatic reaction is completed in <20 min and results in detection limits of 10 colony-forming units for methicillin-resistant Staphylococcus aureus and Salmonella enterica and 100 colony-forming units for Neisseria gonorrhoeae.

The NPs toxicity was evaluated by examining changes in membrane integrity, cell morphology, barrier properties, oxidative stress and inflammatory reactions. AgNPs decreased cell viability, disturbed barrier integrity and tight junctions and triggered oxidative stress and DNA strand breaks. However, all mentioned effects were, at least partly, suppressed by a Citrate-coating and were most pronounced in the cells of the BBB as compared to the epithelial cells representing the blood-CSF barrier. AgEO- but not AgCitrate-NPs also triggered an inflammatory reaction in porcine brain capillary endothelial cells (PBCEC), which represent the BBB.

CROM combines the cluster analysis pioneered in Gunzburger's group (Burkardt, Gunzburger \& Lee, Comput. Meth. Appl. Mech.

CROM constitutes a potential alternative to POD models and generalises the Ulam-Galerkin method classically used in dynamical systems to determine a finite-rank approximation of the Perron-Frobenius operator. The proposed strategy processes a time-resolved sequence of flow snapshots in two steps. First, the snapshot data are clustered into a small number of representative states, called centroids, in the state space. These centroids partition the state space in complementary non-overlapping regions (centroidal Voronoi cells). Departing from the standard algorithm, the probabilities of the clusters are determined, and the states are sorted by analysis of the transition matrix. Second, the transitions between the states are dynamically modelled using a Markov process. Physical mechanisms are then distilled by a refined analysis of the Markov process, e. g. using finite-time Lyapunov exponent (FTLE) and entropic methods. This CROM framework is applied to the Lorenz attractor (as illustrative example), to velocity fields of the spatially evolving incompressible mixing layer and the three-dimensional turbulent wake of a bluff body. For these examples, CROM is shown to identify non-trivial quasi-attractors and transition processes in an unsupervised manner. CROM has numerous potential applications for the systematic identification of physical mechanisms of complex dynamics, for comparison of flow evolution models, for the identification of precursors to desirable and undesirable events, and for flow control applications exploiting nonlinear actuation dynamics.}, language = {en} } @misc{HoosLindauerSchaub2014, author = {Hoos, Holger and Lindauer, Marius and Schaub, Torsten H.}, title = {claspfolio 2}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, number = {606}, issn = {1866-8372}, doi = {10.25932/publishup-41612}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-416129}, pages = {17}, year = {2014}, abstract = {Building on the award-winning, portfolio-based ASP solver claspfolio, we present claspfolio 2, a modular and open solver architecture that integrates several different portfolio-based algorithm selection approaches and techniques.

To demonstrate the performance of the new strategy, we carried out several experiments using collocated GPS and accelerometer. The experimental results show that the baseline shifts of the accelerometer are automatically corrected, and high precision coseismic information of strong ground motion can be obtained in real-time. Additionally, the convergence and precision of the PPP is improved by the combined solution.}, language = {en} } @misc{KlassertGagarinaKauschke2014, author = {Klassert, Annegret and Gagarina, Natalʹja Vladimirovna and Kauschke, Christina}, title = {Object and action naming in Russian- and German- speaking monolingual and bilingual children*}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {531}, issn = {1866-8364}, doi = {10.25932/publishup-41541}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-415415}, pages = {16}, year = {2014}, abstract = {The present study investigates the influence of word category on naming performance in two populations: bilingual and monolingual children.

Picture naming of objects and actions by Russian-German bilingual children (aged 4-7 years) was compared to age-matched monolingual children. The results clearly demonstrate a naming deficit of bilingual children in comparison to monolingual children that increases with age.

In bilingual language acquisition, nouns do not predominate over verbs as much as is seen in monolingual German and Russian children.

As revealed by multivariate analyses, no discernible feeding competition was found in the local assemblage amongst congeneric species as compared with non-congeners.

The question arises as to whether these changes have already had an impact on the residents' ability to cope with floods, and whether flood-affected private households are now better prepared than they were in 2002. Therefore, computer-aided telephone interviews with private households in Germany that suffered from property damage due to flooding in 2005, 2006, 2010 or 2011 were performed and analysed with respect to flood awareness, precaution, preparedness and recovery. The data were compared to a similar investigation conducted after the flood in 2002. After the flood in 2002, the level of private precautions taken increased considerably. One contributing factor is the fact that, in general, a larger proportion of people knew that they were at risk of flooding. The best level of precaution was found before the flood events in 2006 and 2011. The main reason for this might be that residents had more experience with flooding than residents affected in 2005 or 2010. Yet, overall, flood experience and knowledge did not necessarily result in building retrofitting or flood-proofing measures, which are considered as mitigating damages most effectively. Hence, investments still need to be stimulated in order to reduce future damage more efficiently. Early warning and emergency responses were substantially influenced by flood characteristics. In contrast to flood-affected people in 2006 or 2011, people affected by flooding in 2005 or 2010 had to deal with shorter lead times and therefore had less time to take emergency measures. Yet, the lower level of emergency measures taken also resulted from the people's lack of flood experience and insufficient knowledge of how to protect themselves. Overall, it was noticeable that these residents suffered from higher losses. Therefore, it is important to further improve early warning systems and communication channels, particularly in hilly areas with rapid-onset flooding.}, language = {en} } @misc{RolinskiRammigWalzetal.2014, author = {Rolinski, Susanne and Rammig, Anja and Walz, Ariane and von Bloh, Werner and van Oijen, M. and Thonicke, Kirsten}, title = {A probabilistic risk assessment for the vulnerability of the European carbon cycle to weather extremes}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch naturwissenschaftliche Reihe (487)}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch naturwissenschaftliche Reihe (487)}, number = {487}, issn = {1866-8372}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-407999}, pages = {1813 -- 1831}, year = {2014}, abstract = {Extreme weather events are likely to occur more often under climate change and the resulting effects on ecosystems could lead to a further acceleration of climate change. But not all extreme weather events lead to extreme ecosystem response. Here, we focus on hazardous ecosystem behaviour and identify coinciding weather conditions. We use a simple probabilistic risk assessment based on time series of ecosystem behaviour and climate conditions. Given the risk assessment terminology, vulnerability and risk for the previously defined hazard are estimated on the basis of observed hazardous ecosystem behaviour. We apply this approach to extreme responses of terrestrial ecosystems to drought, defining the hazard as a negative net biome productivity over a 12-month period. We show an application for two selected sites using data for 1981-2010 and then apply the method to the pan-European scale for the same period, based on numerical modelling results (LPJmL for ecosystem behaviour; ERA-Interim data for climate). Our site-specific results demonstrate the applicability of the proposed method, using the SPEI to describe the climate condition. The site in Spain provides an example of vulnerability to drought because the expected value of the SPEI is 0.4 lower for hazardous than for non-hazardous ecosystem behaviour. In northern Germany, on the contrary, the site is not vulnerable to drought because the SPEI expectation values imply wetter conditions in the hazard case than in the non-hazard case. At the pan-European scale, ecosystem vulnerability to drought is calculated in the Mediterranean and temperate region, whereas Scandinavian ecosystems are vulnerable under conditions without water shortages. These first model- based applications indicate the conceptual advantages of the proposed method by focusing on the identification of critical weather conditions for which we observe hazardous ecosystem behaviour in the analysed data set. Application of the method to empirical time series and to future climate would be important next steps to test the approach.}, language = {en} } @article{HaferKiyLucke2014, author = {Hafer, J{\"o}rg and Kiy, Alexander and Lucke, Ulrike}, title = {Moodle \& Co. auf dem Weg zur Personal Learning Environment}, series = {eleed}, volume = {2014}, journal = {eleed}, number = {10}, issn = {1860-7470}, year = {2014}, abstract = {Ausgehend von der typischen IT-Infrastruktur f{\"u}r E-Learning an Hochschulen auf der einen Seite sowie vom bisherigen Stand der Forschung zu Personal Learning Environments (PLEs) auf der anderen Seite zeigt dieser Beitrag auf, wie bestehende Werkzeuge bzw.

Our investigation reveals marked changes in spatial and temporal distributions of the major arboreal taxa. The thermophilous (Castanea, Castanopsis, Cyclobalanopsis, Fagus, Pterocarya) and eurythermal (Juglans, Quercus, Tilia, Ulmus) broadleaved tree taxa were restricted to the current tropical or subtropical areas of China during the Last Glacial Maximum (LGM) and spread northward since c. 14.5 kyr BP. Betula and conifer taxa (Abies, Picea, Pinus), in contrast, retained a wider distribution during the LGM and showed no distinct expansion direction during the Late Glacial. Since the late mid-Holocene, the abundance but not the spatial extent of most trees decreased. The changes in spatial and temporal distributions for the 14 taxa are a reflection of climate changes, in particular monsoonal moisture, and, in the late Holocene, human impact.

A sediment core covering the last 55years from a small closed-basin lake in central Mongolia was analyzed for its multi-proxy record at annual resolution. Pollen analysis shows that highest abundances of planted Poaceae and highest vegetation diversity occurred during 1977-1992, reflecting agricultural development in the lake area. A decrease in diversity and an increase in Artemisia abundance after 1992 indicate enhanced vegetation degradation in recent times, most probably because of overgrazing and farmland abandonment. Human impact is the main factor for the vegetation degradation within the past decades as revealed by a series of redundancy analyses, while climate change and soil erosion play subordinate roles. High Pediastrum (a green algae) influx, high atomic total organic carbon/total nitrogen (TOC/TN) ratios, abundant coarse detrital grains, and the decrease of C-13(org) and N-15 since about 1977 but particularly after 1992 indicate that abundant terrestrial organic matter and nutrients were transported into the lake and caused lake eutrophication, presumably because of intensified land use.
