  abstract  = {The new edition of the Potsdam Research Magazine "Portal Wissen" approaches the subject "Borders" from different perspectives. As a linguist, this headline makes me think of linguistic borders and the effects that might result from the contact of two languages at a particular border. There is, for instance, ample evidence of code-switching, i.e. the use of material from at least two languages in a single utterance. The reasons for code-switching can be manifold. On the one hand, code-switching may result from a limited language competence, for example if a speaker lacks a particular word in a nonnative language. On the other hand, code-switching may be a matter of prestige if the speaker wants to demonstrate his or her affiliation to a certain social group by switching languages. If code-switching does not only occur sporadically but involves whole language communities over a longer period of time, it can result in significant changes of the involved languages. Which language "gives" and which one "takes" is determined by sociolinguistic factors. It is, hence, quite easy to predict that German varieties spoken in language islands in South and Eastern Europe as well as in North and Latin America will absorb more and more language material from their neighbouring languages until they disappear unless political will strives to preserve these language varieties. Increasing mobility of modern societies has multiplied the extent and the intensity of language contact and certainly comprises a large number of different contact situations besides the one most commonly known, i.e. the contact between German and English. From a historic point of view, German witnesses a strong influence of various Romance languages such as Latin, French and Italian. In Potsdam, one cannot help being reminded of the French influence during the 18th century. Overcoming language borders becomes also apparent in the everyday life of an international research university. In March this year, the Annual Conference of the German Linguistic Society took place in Potsdam, with more than 500 participants. Lingua franca of this conference was English. Compared to previous conferences, this further increased the number of international participants. The articles in this edition illustrate various approaches to the topic "Borders": On the trail of "Boundary Surveys", we follow the Australian explorer Ludwig Leichhardt. "Travellers Across Borders" is focussed on articles dealing with the literature of the colonial Caribbean or with the work of an Italian geologist deep beneath the earth's surface, for example. Looking for the "Boundless", our authors follow scientists who discuss questions like "Why love hurts?". The present issue of "Portal Wissen" also takes into account "Drawing Up Borders" in an article that is concerned with the limits of workrelated stress. Instances of successful "Border Crossing" are provided by the "Handkerchief Lab" as well as by new biotechnological applications. I would like to wish you inspiring border experiences, hoping that you will get many impulses for crossing professional borders in your field of expertise.

  abstract  = {The latest edition of our Potsdam Research Magazine "Portal Wissen" addresses the topic "Layers" in many different ways. Geoscientists often deal with layers: layers of soil, sediment, or rock are the evidence of repeated and long-lasting processes of erosion and sedimentation that took place in the early history of the earth. For instance, mountains are eroded by water, ice and wind. The sand that results from that erosion might eventually form a new layer on the ocean floor known as a sediment horizon. After tens of millions of years, tectonic plate movements can deform the ocean floor, pushing it upwards as mountains are created, bringing the layers of sand from former mountain chains together with fossilized sea dwellers into the realm of climbers and mountaineers - a fundamental cycle within the Earth system that was succinctly described by Ibn Sina nearly 1000 years ago, and later by Charles Darwin when he was crossing the Andes. The landscape around us overlays the products of recent processes with those from the past. Slow processes or extreme events that happen very rarely - like floods, earthquakes or rockslides - wipe out certain characteristics, while others remain on the surface. In this sense, the landscape is like a palimpsest - a piece of parchment that monks in the Middle Ages scraped clean again and again to write something new. Analysing rock layers and soil is similar to the work of a detective. Geophysical deep sounding with sound and radar waves, precise measurements of motions related to earthquakes, and deep boreholes each provide a glimpse of the characteristics of what lies beneath us, giving us a better understanding of spatial distribution of the various layers. Fossils can tell us the age of a layer of sediment, while radiometric isotopes in minerals reveal how quickly a rock moved from deep within the Earth up to the surface, perhaps during the process of mountain building. Thin layers of ash tell us when there was a devastating volcanic eruption that influenced environmental conditions. The shape, gradation, and surface conditions of sand grains reflect whether wind or water was responsible for their transport. We know, for instance, that northern Germany was a desert landscape more than 260 million years ago. At that time, the wind made huge dunes migrate across the region. Over time, climate and vegetation slowly alter the physical and chemical characteristics of sand and rock at the surface, turning them into soil, the epidermis of our planet. Mineralogical analyses of layers of the soil layer tell us whether the climate was dry or wet. These kinds of observations allow us to reconstruct links between our climate system and processes that have taken place on the Earth's surface, as well as those processes that originate at much deeper levels. The clues we use might be hidden under the surface of the earth or clearly visible on the surface, like in the mountains, or even in freshly cut rock alongside roads. On the following pages, we invite you to accompany scientists from Potsdam into their world of research. They track hidden traces of longgone earthquakes in the Tien Shan Mountains; they discover ancient forms of life in deep-sea sediments. They even examine layers in outer space that can tell us something about the formation of planets. "Portal Wissen" not only presents scientists of the University of Potsdam who deal with the sequence of layers formed by solid rock, but also those scientists who deal with levels of education or social strata. Research scientists explain how to implement the social mission of inclusion in teaching, and how pupils from the Berlin district Kreuzberg examine language in urban neighbourhoods together with students from the University of Potsdam. Although these types of "layers" are very different, they all have something in common. Their structure and profile are evidence of continuously changing conditions. The present will leave traces and layers that future geoscientists will measure and examine. We already speak of the Anthropocene, a geological era dominated by humans, which is characterized by far-reaching changes in erosion and sedimentation rates, and the displacement of natural habitats. I hope that you will discover exciting and inspiring stories in this edition. And remember - it is always worth having a look beneath the surface. Prof. Manfred Strecker, PHD Professor of Geology},

  abstract  = {Die neue Ausgabe des Potsdamer Forschungsmagazins widmet sich dem Thema „Grenzen" aus unterschiedlichsten Perspektiven. Als Sprachwissenschaftlerin denke ich bei diesem Stichwort an sprachliche Grenzen und die Wirkungen, die sich aus dem Kontakt von zwei Sprachen an einer Sprachgrenze ergeben k{\"o}nnen. Vielf{\"a}ltig sind die Belege f{\"u}r das sogenannte Code-Switching, dem Wechsel von einer Sprache in die andere in einer bestimmten {\"A}ußerungssituation. Die Motive f{\"u}r einen solchen Sprachwechsel k{\"o}nnen ganz unterschiedlicher Natur sein: So l{\"a}sst sich Code-Switching einerseits auf eine eingeschr{\"a}nkte sprachliche Kompetenz zur{\"u}ckf{\"u}hren, wenn beispielsweise einer Sprecherin ein bestimmtes Wort in der Zweitsprache fehlt, andererseits kann das Code-Switching prestigebedingt sein, wenn ein Sprecher durch einen sprachlichen Wechsel seine Zugeh{\"o}rigkeit zu einer bestimmten gesellschaftlichen Gruppe demonstrieren m{\"o}chte. Wenn Code-Switching nicht nur punktuell stattfindet, sondern ganze Sprach- gemeinschaften {\"u}ber einen l{\"a}ngeren Zeitraum erfasst, kann es zu weitreichenden Ver{\"a}nderungen der betroffenen Sprachen kommen. Welche Sprache „gibt" und welche Sprache „nimmt", h{\"a}ngt von sprachexternen Faktoren ab. So ist es ein Leichtes vorherzusagen, dass die deutschen Variet{\"a}ten der Sprachinseln in S{\"u}d- und Osteuropa wie auch in Nord- und S{\"u}damerika wohl zunehmend Material und Muster aus den sie umgebenden Sprachen aufnehmen und letztendlich in ihnen aufgehen werden, wenn sie nicht durch politischen Willen konserviert werden. Das Ausmaß von Sprachkontakt ist mit der zunehmenden r{\"a}umlichen Mobilit{\"a}t moderner Gesellschaften stark angestiegen, und l{\"a}sst sich sicher nicht auf den aktuell immer wieder thematisierten Sprachkontakt des Deutschen mit dem Englischen reduzieren. Historisch gesehen ist das Deutsche vor allem durch die romanischen Sprachen stark gepr{\"a}gt worden - in Potsdam denkt man hier unwillk{\"u}rlich an den starken Einfluss des Franz{\"o}sischen im 18. Jahrhundert. Die {\"U}berwindung sprachlicher Grenzen zeigt sich auch im Alltag einer international ausgerichteten Forschungsuniversit{\"a}t: So hat im M{\"a}rz dieses Jahres in Potsdam die Jahrestagung der deutschen Gesellschaft f{\"u}r Sprachwissenschaft mit {\"u}ber 500 Teilnehmern stattgefunden. Lingua Franca der Tagung war Englisch, was den Anteil der internationalen Teilnehmer gegen{\"u}ber fr{\"u}heren Jahrestagungen nochmals vergr{\"o}ßert hat. Zahlreiche andere Zug{\"a}nge zum Thema Grenzen bieten die Beitr{\"a}ger dieser Ausgabe des Forschungsmagazins: Auf den Spuren von „Grenzvermessungen" bewegen sich die Texte zum Australienforscher Ludwig Leichhardt oder zur Energiebilanz im Spitzensport. „Grenzg{\"a}nger" stehen im Fokus der Beitr{\"a}ge {\"u}ber eine Forschergruppe zur Literatur der kolonialen Karibik oder die tief in die Erde reichenden Forschungen eines italienischen Geologen. Auf der Suche nach dem „Grenzenlosen" folgen die Autoren den Wissenschaftlern etwa zur Frage „Why love hurts?" oder hinein in eine Geschichte des Musikh{\"o}rens. Den umgekehrten Weg, n{\"a}mlich „Grenzziehungen", beobachtet „Portal Wissen" in der Arbeit des Potsdamer MenschenRechtsZentrums oder den Auswertungen des Nationalen Dopingpr{\"a}ventionsplans. Belege f{\"u}r erfolgreiche „Grenz{\"u}berschreitungen" liefern schließlich Blicke ins „Taschentuchlabor" oder die digitale Edition mittelalterlicher Prosaepen, um nur einige Beitr{\"a}ge aus diesem Heft herauszugreifen. Ich w{\"u}nsche Ihnen bei der Lekt{\"u}re anregende Grenzerfahrungen mit vielen Impulsen f{\"u}r eigene fachliche Grenz{\"u}berschreitungen.

  abstract  = {Die neue Ausgabe unseres Potsdamer Forschungsmagazins widmet sich ganz und gar und auf sehr unterschiedliche Weise dem Thema „Schichten". Als Geowissenschaftler begegnen mir Schichten h{\"a}ufig: Boden-, Sedimentoder Gesteinsschichten - sie sind das Zeugnis lang anhaltender und immer wiederkehrender Erosionsund Ablagerungsprozesse, wie sie schon in der fr{\"u}hen Erdgeschichte stattfanden. Gebirge werden beispielsweise durch Wasser, Eis und Wind erodiert. Die Erosionsprodukte bilden vielleicht irgendwann auf dem Meeresgrund als Ablagerungshorizont eine neue Schicht. Umgekehrt f{\"u}hren Deformationsprozesse als Folge von tektonischen Plattenbewegungen dazu, dass Gebirge entstehen und der Mensch versteinerte Meeresbewohner in verfalteten Sedimentschichten im Hochgebirge findet - Beziehungen, wie sie bereits von Ibn Sina und sp{\"a}ter von Charles Darwin bei seiner Anden{\"u}berquerung beschrieben wurden. Aber auch die Landschaft, die wir bei einem Blick aus dem Fenster wahrnehmen, ist nichts anderes als das Produkt verschiedener {\"U}berlagerungen von Prozessen Liebe Leserinnen und Leser, in der Vergangenheit und heute. Langsam ablaufende Prozesse oder seltener stattfindende Extremereignisse wie Fluten, Erdbeben oder Bergst{\"u}rze - einzelne Merkmale werden dabei ausgel{\"o}scht, andere treten zutage. {\"A}hnlich einem Palimpsest - einem St{\"u}ck Pergament, das die M{\"o}nche im Mittelalter immer wieder abgeschabt und neu {\"u}berschrieben haben. Die Analyse von Gesteins- und Bodenschichten gleicht der Arbeit eines Detektivs. Geophysikalische Tiefensondierungen mit Schall- und Radarwellen, die genaue Vermessung von Erdbebenherden oder Tiefbohrungen bringen uns verdeckte Erdschichten n{\"a}her. Fossilienfunde und radiometrische Datierungen verraten das Alter einer Schicht. Mithilfe d{\"u}nner Ascheschichten k{\"o}nnen wir nachweisen, wann verheerende Vulkanausbr{\"u}che Umweltbedingungen beeinflusst haben. B{\"o}den, die Epidermis unseres Planeten, spiegeln die Eigenschaften der darunterliegenden Gesteinsschichten, der Vegetationsbedeckung oder den Einfluss des Klimas wider. Die Form, Sortierung und Oberfl{\"a}chenbeschaffenheit von Sandk{\"o}rnern lassen uns erkennen, ob Wind oder Wasser f{\"u}r ihren Transport gesorgt haben. So wissen wir, dass Norddeutschland vor {\"u}ber 260 Millionen Jahren eine W{\"u}stenlandschaft war, in der der Wind m{\"a}chtige D{\"u}nen wandern ließ. Die mineralogische Untersuchung damit verbundener Schichten verr{\"a}t, ob das Klima trocken oder feucht war. So dechiffrieren wir Hinweise auf vergangene Prozesse, die unter der Erdoberfl{\"a}che versteckt sind oder - wie etwa in Gebirgen - offen zutage treten. Auf den kommenden Seiten laden wir Sie ein, Potsdamer Wissenschaftler an die Orte ihrer Forschung zu begleiten: Im Tien Shan-Gebirge sp{\"u}ren sie l{\"a}ngst vergangene Erdbeben auf, in Tiefseesedimenten entdecken sie uralte Lebensformen und im Weltall erforschen sie gar Schichten, die uns etwas {\"u}ber die Entstehung von Planeten verraten. Die Wissenschaftler der Universit{\"a}t Potsdam beschr{\"a}nken sich allerdings nicht auf die Schichtabfolgen der festen Erde. „Portal Wissen" blickt auch jenen Wissenschaftlern {\"u}ber die Schulter, die sich mit „Bildungsschichten" oder „Gesellschaftsschichten" befassen. So erkl{\"a}ren Forscher, wie der gesellschaftliche Auftrag der Inklusion in der Lehre umgesetzt wird oder wie Kreuzberger Sch{\"u}ler zusammen mit Potsdamer Studierenden Sprache im urbanen Raum erforschen. So unterschiedlich sie sind, eines ist allen diesen „Schichten" gemeinsam: Ihre Struktur und Form sind Zeugnis sich immer wieder ver{\"a}ndernder Rahmenbedingungen. Auch die Gegenwart wird Spuren und Schichten hinterlassen, die zuk{\"u}nftige Erdwissenschaftler vermessen und untersuchen werden. Schon jetzt spricht man vom Anthropoz{\"a}n, einem vom Menschen dominierten geologischen Zeitabschnitt, charakterisiert durch tiefgreifende {\"A}nderungen in den Erosions- und Sedimentationsraten und der Verdr{\"a}ngung nat{\"u}rlicher Lebensr{\"a}ume. Ich w{\"u}nsche Ihnen, dass Sie in diesem Heft spannende und anregende Geschichten entdecken. Denn es lohnt sich, einen Blick unter die Oberfl{\"a}che zu werfen. Prof. Manfred Strecker, PhD.

  abstract  = {Background: Recent studies have demonstrated a superior diagnostic accuracy of cardiovascular magnetic resonance (CMR) for the detection of coronary artery disease (CAD). We aimed to determine the comparative cost-effectiveness of CMR versus single-photon emission computed tomography (SPECT). Methods: Based on Bayes' theorem, a mathematical model was developed to compare the cost-effectiveness and utility of CMR with SPECT in patients with suspected CAD. Invasive coronary angiography served as the standard of reference. Effectiveness was defined as the accurate detection of CAD, and utility as the number of quality-adjusted life-years (QALYs) gained. Model input parameters were derived from the literature, and the cost analysis was conducted from a German health care payer's perspective. Extensive sensitivity analyses were performed. Results: Reimbursement fees represented only a minor fraction of the total costs incurred by a diagnostic strategy. Increases in the prevalence of CAD were generally associated with improved cost-effectiveness and decreased costs per utility unit (Delta QALY). By comparison, CMR was consistently more cost-effective than SPECT, and showed lower costs per QALY gained. Given a CAD prevalence of 0.50, CMR was associated with total costs of (sic)6,120 for one patient correctly diagnosed as having CAD and with (sic)2,246 per Delta QALY gained versus (sic)7,065 and (sic)2,931 for SPECT, respectively. Above a threshold value of CAD prevalence of 0.60, proceeding directly to invasive angiography was the most cost-effective approach. Conclusions: In patients with low to intermediate CAD probabilities, CMR is more cost-effective than SPECT. Moreover, lower costs per utility unit indicate a superior clinical utility of CMR.},

  abstract  = {We study origin, parameter optimization, and thermodynamic efficiency of isothermal rocking ratchets based on fractional subdiffusion within a generalized non-Markovian Langevin equation approach. A corresponding multi-dimensional Markovian embedding dynamics is realized using a set of auxiliary Brownian particles elastically coupled to the central Brownian particle (see video on the journal web site). We show that anomalous subdiffusive transport emerges due to an interplay of nonlinear response and viscoelastic effects for fractional Brownian motion in periodic potentials with broken space-inversion symmetry and driven by a time-periodic field. The anomalous transport becomes optimal for a subthreshold driving when the driving period matches a characteristic time scale of interwell transitions. It can also be optimized by varying temperature, amplitude of periodic potential and driving strength. The useful work done against a load shows a parabolic dependence on the load strength. It grows sublinearly with time and the corresponding thermodynamic efficiency decays algebraically in time because the energy supplied by the driving field scales with time linearly. However, it compares well with the efficiency of normal diffusion rocking ratchets on an appreciably long time scale.},

The reconnection occurred between magnetic fields of the laterally expanding CME and a neighbouring active region. A pre-existing quasi-separatrix layer was activated in the process. This scenario is supported by data-constrained numerical simulations of the eruption. Observations show that dense cool filament plasma was re-directed and heated in situ, producing coronal-temperature emission around the reconnection region. These results provide the first direct observational evidence, supported by MHD simulations and magnetic modelling, that a large-scale re-configuration of the coronal magnetic field takes place during solar eruptions via the process of magnetic reconnection.},

The flux ropes are formed in the solar atmosphere by the process known as flux cancellation and are stable for several hours before the eruption. The observations also indicate that the magnetic structure that erupts is not the entire flux rope as initially formed, raising the question of whether the flux rope is able to undergo a partial eruption or whether it undergoes a transition in specific flux rope configuration shortly before the CME.},

A total of 4546 oropharyngeal swab samples from 18 bat species were screened for the presence of EBLV-1- , EBLV-2- and BBLV-specific RNA. Overall, 0 center dot 15\% of oropharyngeal swab samples tested EBLV-1 positive, with the majority originating from Eptesicus serotinus. Interestingly, out of seven RT-PCR-positive oropharyngeal swabs subjected to virus isolation, viable virus was isolated from a single serotine bat (E. serotinus). Additionally, about 1226 blood samples were tested serologically, and varying virus neutralizing antibody titres were found in at least eight different bat species. The detection of viral RNA and seroconversion in repeatedly sampled serotine bats indicates long-term circulation of the virus in a particular bat colony. The limitations of random-based active bat rabies surveillance over passive bat rabies surveillance and its possible application of targeted approaches for future research activities on bat lyssavirus dynamics and maintenance are discussed.},

We elaborate upon such a qualitative approach aiming at the computation of minimal interventions in logical signaling networks relying on Kleene's three-valued logic and fixpoint semantics.

The experiment showed different priming patterns for the two participant groups. The L1 German data yielded a stem-priming effect for inflected forms involving regular affixation and a partial priming effect for irregular forms irrespective of stem allomorphy. By contrast, the data from the late bilinguals showed reduced priming effects for both regular and irregular forms. We argue that late learners rely more on lexically stored inflected word forms during word recognition and less on morphological parsing than native speakers.},

Using an elicitation task, the production of inflected nonce verb forms (3 rd person singular with -t suffix) with either high- or low-frequency subsyllables was tested in sixteen German-learning children with SLI (ages 4;1-5 ;1), sixteen TD-children matched for chronological age (CA) and fourteen TD- children matched for verbal age (VA) (ages 3;0-3 ;11). The findings revealed that children with SLI, but not CA- or VA-children, showed differential performance between the two types of verbs, producing more inflectional errors when the verb forms resulted in low-frequency subsyllables than when they resulted in high-frequency subsyllables, replicating the results from English-learning children.},

  abstract  = {The course timetabling problem can be generally defined as the task of assigning a number of lectures to a limited set of timeslots and rooms, subject to a given set of hard and soft constraints. The modeling language for course timetabling is required to be expressive enough to specify a wide variety of soft constraints and objective functions. Furthermore, the resulting encoding is required to be extensible for capturing new constraints and for switching them between hard and soft, and to be flexible enough to deal with different formulations. In this paper, we propose to make effective use of ASP as a modeling language for course timetabling. We show that our ASP-based approach can naturally satisfy the above requirements, through an ASP encoding of the curriculum-based course timetabling problem proposed in the third track of the second international timetabling competition (ITC-2007). Our encoding is compact and human-readable, since each constraint is individually expressed by either one or two rules. Each hard constraint is expressed by using integrity constraints and aggregates of ASP. Each soft constraint S is expressed by rules in which the head is the form of penalty (S, V, C), and a violation V and its penalty cost C are detected and calculated respectively in the body. We carried out experiments on four different benchmark sets with five different formulations. We succeeded either in improving the bounds or producing the same bounds for many combinations of problem instances and formulations, compared with the previous best known bounds.},

We discuss the time evolution of the number of surface-bound particles, the effective surface mean squared displacement, and the surface propagator. In particular, we observe sub- and superdiffusive regimes. A plateau of the surface mean-squared displacement reflects a stalling of the surface diffusion at longer times. Finally, the corresponding first passage problem for the cylindrical geometry is analysed.},

It argues that political parties bargain over potential office-holders during government-formation processes, selecting future cabinet ministers from an emerging bargaining pool'. The article draws upon a new dataset comprising all ministrable candidates discussed by political parties during eight government-formation processes in Germany between 1983 and 2009. The conditional logit regression analysis reveals that temporal dynamics, such as the day she enters the pool, have a significant effect on her success in achieving a cabinet position. Other determinants of ministerial selection discussed in the existing literature, such as party and parliamentary expertise, are less relevant for achieving ministerial office. The article concludes that scholarship on ministerial selection requires a stronger emphasis for its endogenous nature in government-formation as well as the relevance of temporal dynamics in such processes.},

  abstract  = {OCP-Place, a cross-linguistically well-attested constraint against pairs of consonants with shared [place], is psychologically real. Studies have shown that the processing of words violating OCP-Place is inhibited. Functionalists assume that OCP arises as a consequence of low-level perception: a consonant following another with the same [place] cannot be faithfully perceived as an independent unit. If functionalist theories were correct, then lexical access would be inhibited if two homorganic consonants conjoin at word boundaries-a problem that can only be solved with lexical feedback. Here, we experimentally challenge the functional account by showing that OCP-Place can be used as a speech segmentation cue during pre-lexical processing without lexical feedback, and that the use relates to distributions in the input. In Experiment 1, native listeners of Dutch located word boundaries between two labials when segmenting an artificial language. This indicates a use of OCP-Labial as a segmentation cue, implying a full perception of both labials. Experiment 2 shows that segmentation performance cannot solely be explained by well-formedness intuitions. Experiment 3 shows that knowledge of OCP-Place depends on language-specific input: in Dutch, co-occurrences of labials are under-represented, but co-occurrences of coronals are not. Accordingly, Dutch listeners fail to use OCP-Coronal for segmentation.},

Study 2 explored longitudinal relations among prosocial-video-game use, violent-video-game use, empathy, and helping in a large sample of Singaporean children and adolescents measured three times across 2 years. Path analyses showed significant longitudinal effects of prosocial- and violent-video-game use on prosocial behavior through empathy. Latent-growth-curve modeling for the 2-year period revealed that change in video-game use significantly affected change in helping, and that this relationship was mediated by change in empathy.},

The first study employed the masked priming technique to investigate -ed forms with a group of advanced Arabic-speaking learners of English. The results replicate previously found L1/L2 differences in morphological priming, even though in the present experiment an extra temporal delay was offered after the presentation of the prime words. The second study examined the timing of constraints against inflected forms inside derived words in English using the eye-movement monitoring technique and an additional acceptability judgment task with highly advanced Dutch L2 learners of English in comparison to adult L1 English controls. Whilst offline the L2 learners performed native-like, the eye-movement data showed that their online processing was not affected by the morphological constraint against regular plurals inside derived words in the same way as in native speakers. Taken together, these findings indicate that L2 learners are not just slower than native speakers in processing morphologically complex words, but that the L2 comprehension system employs real-time grammatical analysis (in this case, morphological information) less than the L1 system.},

  abstract  = {Background: Neuroenhancement (NE), the use of psychoactive substances in order to enhance a healthy individual's cognitive functioning from a proficient to an even higher level, is prevalent in student populations. According to the strength model of self-control, people fail to self-regulate and fall back on their dominant behavioral response when finite self-control resources are depleted. An experiment was conducted to test the hypothesis that ego-depletion will prevent students who are unfamiliar with NE from trying it. Findings: 130 undergraduates, who denied having tried NE before (43\% female, mean age = 22.76 +/- 4.15 years old), were randomly assigned to either an ego-depletion or a control condition. The dependent variable was taking an "energy-stick" (a legal nutritional supplement, containing low doses of caffeine, taurine and vitamin B), offered as a potential means of enhancing performance on the bogus concentration task that followed. Logistic regression analysis showed that ego-depleted participants were three times less likely to take the substance, OR = 0.37, p = .01. Conclusion: This experiment found that trying NE for the first time was more likely if an individual's cognitive capacities were not depleted. This means that mental exhaustion is not predictive for NE in students for whom NE is not the dominant response. Trying NE for the first time is therefore more likely to occur as a thoughtful attempt at self-regulation than as an automatic behavioral response in stressful situations. We therefore recommend targeting interventions at this inter-individual difference. Students without previous reinforcing NE experience should be provided with information about the possible negative health outcomes of NE. Reconfiguring structural aspects in the academic environment (e.g. lessening workloads) might help to deter current users.},

  abstract  = {Background: Short lived, iteroparous animals in seasonal environments experience variable social and environmental conditions over their lifetime. Animals can be divided into those with a "young-of-the-year" life history (YY, reproducing and dying in the summer of birth) and an "overwinter" life history (OW, overwintering in a subadult state before reproducing next spring). We investigated how behavioural patterns across the population were affected by season and sex, and whether variation in behaviour reflects the variation in life history patterns of each season. Applications of pace-of-life (POL) theory would suggest that long-lived OW animals are shyer in order to increase survival, and YY are bolder in order to increase reproduction. Therefore, we expected that in winter and spring samples, when only OW can be sampled, the animals should be shyer than in summer and autumn, when both OW and YY animals can be sampled. We studied common vole (Microtus arvalis) populations, which express typical, intra-annual density fluctuation. We captured a total of 492 voles at different months over 3 years and examined boldness and activity level with two standardised behavioural experiments. Results: Behavioural variables of the two tests were correlated with each other. Boldness, measured as short latencies in both tests, was extremely high in spring compared to other seasons. Activity level was highest in spring and summer, and higher in males than in females. Conclusion: Being bold in laboratory tests may translate into higher risk-taking in nature by being more mobile while seeking out partners or valuable territories. Possible explanations include asset-protection, with OW animals being rather old with low residual reproductive value in spring. Therefore, OW may take higher risks during this season. Offspring born in spring encounter a lower population density and may have higher reproductive value than offspring of later cohorts. A constant connection between life history and animal personality, as suggested by the POL theory, however, was not found. Nevertheless, correlations of traits suggest the existence of animal personalities. In conclusion, complex patterns of population dynamics, seasonal variation in life histories, and variability of behaviour due to asset-protection may cause complex seasonal behavioural dynamics in a population.},

  abstract  = {Background: Adaptive behavioural strategies promoting co-occurrence of competing species are known to result from a sympatric evolutionary past. Strategies should be different for indirect resource competition (exploitation, e.g., foraging and avoidance behaviour) than for direct interspecific interference (e.g., aggression, vigilance, and nest guarding). We studied the effects of resource competition and nest predation in sympatric small mammal species using semi-fossorial voles and shrews, which prey on vole offspring during their sensitive nestling phase. Experiments were conducted in caged outdoor enclosures. Focus common vole mothers (Microtus arvalis) were either caged with a greater white-toothed shrew (Crocidura russula) as a potential nest predator, with an herbivorous field vole (Microtus agrestis) as a heterospecific resource competitor, or with a conspecific resource competitor. Results: We studied behavioural adaptations of vole mothers during pregnancy, parturition, and early lactation, specifically modifications of the burrow architecture and activity at burrow entrances. Further, we measured pre- and postpartum faecal corticosterone metabolites (FCMs) of mothers to test for elevated stress hormone levels. Only in the presence of the nest predator were prepartum FCMs elevated, but we found no loss of vole nestlings and no differences in nestling body weight in the presence of the nest predator or the heterospecific resource competitor. Although the presence of both the shrew and the field vole induced prepartum modifications to the burrow architecture, only nest predators caused an increase in vigilance time at burrow entrances during the sensitive nestling phase. Conclusion: Voles displayed an adequate behavioural response for both resource competitors and nest predators. They modified burrow architecture to improve nest guarding and increased their vigilance at burrow entrances to enhance offspring survival chances. Our study revealed differential behavioural adaptations to resource competitors and nest predators.},

  abstract  = {Movement of organisms is one of the key mechanisms shaping biodiversity, e.g. the distribution of genes, individuals and species in space and time. Recent technological and conceptual advances have improved our ability to assess the causes and consequences of individual movement, and led to the emergence of the new field of 'movement ecology'. Here, we outline how movement ecology can contribute to the broad field of biodiversity research, i.e. the study of processes and patterns of life among and across different scales, from genes to ecosystems, and we propose a conceptual framework linking these hitherto largely separated fields of research. Our framework builds on the concept of movement ecology for individuals, and demonstrates its importance for linking individual organismal movement with biodiversity. First, organismal movements can provide 'mobile links' between habitats or ecosystems, thereby connecting resources, genes, and processes among otherwise separate locations. Understanding these mobile links and their impact on biodiversity will be facilitated by movement ecology, because mobile links can be created by different modes of movement (i.e., foraging, dispersal, migration) that relate to different spatiotemporal scales and have differential effects on biodiversity. Second, organismal movements can also mediate coexistence in communities, through 'equalizing' and 'stabilizing' mechanisms. This novel integrated framework provides a conceptual starting point for a better understanding of biodiversity dynamics in light of individual movement and space-use behavior across spatiotemporal scales. By illustrating this framework with examples, we argue that the integration of movement ecology and biodiversity research will also enhance our ability to conserve diversity at the genetic, species, and ecosystem levels.},

  abstract  = {Background Appearance-related social pressure plays an important role in the development of a negative body image and self-esteem as well as severe mental disorders during adolescence (e.g. eating disorders, depression). Identifying who is particularly affected by social pressure can improve targeted prevention and intervention, but findings have either been lacking or controversial. Thus the aim of this study is to provide a detailed picture of gender, weight, and age-related variations in the perception of appearance-related social pressure by peers and parents. Methods 1112 German students between grades 7 and 9 (mean age: M = 13.38, SD = .81) filled in the Appearance-Related Social Pressure Questionnaire (German: FASD), which considers different sources (peers, parents) as well as various kinds of social pressure (e.g. teasing, modeling, encouragement). Results Girls were more affected by peer pressure, while gender differences in parental pressure seemed negligible. Main effects of grade-level suggested a particular increase in indirect peer pressure (e.g. appearance-related school and class norms) from early to middle adolescence. Boys and girls with higher BMI were particularly affected by peer teasing and exclusion as well as by parental encouragement to control weight and shape. Conclusion The results suggest that preventive efforts targeting body concerns and disordered eating should bring up the topic of appearance pressure in a school-based context and should strengthen those adolescents who are particularly at risk - in our study, girls and adolescents with higher weight status. Early adolescence and school transition appear to be crucial periods for these efforts. Moreover, the comprehensive assessment of appearance-related social pressure appears to be a fruitful way to further explore social risk-factors in the development of a negative body image.},

  abstract  = {Background: The use of psychoactive substances to neuroenhance cognitive performance is prevalent. Neuroenhancement (NE) in everyday life and doping in sport might rest on similar attitudinal representations, and both behaviors can be theoretically modeled by comparable means-to-end relations (substance-performance). A behavioral (not substance-based) definition of NE is proposed, with assumed functionality as its core component. It is empirically tested whether different NE variants (lifestyle drug, prescription drug, and illicit substance) can be regressed to school stressors. Findings: Participants were 519 students (25.8 +/- 8.4 years old, 73.1\% female). Logistic regressions indicate that a modified doping attitude scale can predict all three NE variants. Multiple NE substance abuse was frequent. Overwhelming demands in school were associated with lifestyle and prescription drug NE. Conclusions: Researchers should be sensitive for probable structural similarities between enhancement in everyday life and sport and systematically explore where findings from one domain can be adapted for the other. Policy makers should be aware that students might misperceive NE as an acceptable means of coping with stress in school, and help to form societal sensitivity for the topic of NE among our younger ones in general.},

  abstract  = {Background Natural accessions of Arabidopsis thaliana are a well-known system to measure levels of intraspecific genetic variation. Leaf starch content correlates negatively with biomass. Starch is synthesized by the coordinated action of many (iso)enzymes. Quantitatively dominant is the repetitive transfer of glucosyl residues to the non-reducing ends of α-glucans as mediated by starch synthases. In the genome of A. thaliana, there are five classes of starch synthases, designated as soluble starch synthases (SSI, SSII, SSIII, and SSIV) and granule-bound synthase (GBSS). Each class is represented by a single gene. The five genes are homologous in functional domains due to their common origin, but have evolved individual features as well. Here, we analyze the extent of genetic variation in these fundamental protein classes as well as possible functional implications on transcript and protein levels. Findings Intraspecific sequence variation of the five starch synthases was determined by sequencing the entire loci including promoter regions from 30 worldwide distributed accessions of A. thaliana. In all genes, a considerable number of nucleotide polymorphisms was observed, both in non-coding and coding regions, and several amino acid substitutions were identified in functional domains. Furthermore, promoters possess numerous polymorphisms in potentially regulatory cis-acting regions. By realtime experiments performed with selected accessions, we demonstrate that DNA sequence divergence correlates with significant differences in transcript levels. Conclusions Except for AtSSII, all starch synthase classes clustered into two or three groups of haplotypes, respectively. Significant difference in transcript levels among haplotype clusters in AtSSIV provides evidence for cis-regulation. By contrast, no such correlation was found for AtSSI, AtSSII, AtSSIII, and AtGBSS, suggesting trans-regulation. The expression data presented here point to a regulation by common trans-regulatory transcription factors which ensures a coordinated action of the products of these four genes during starch granule biosynthesis. The apparent cis-regulation of AtSSIV might be related to its role in the initiation of de novo biosynthesis of granules.},

  abstract  = {Introduction: We examined patterns of genetic divergence in 26 Mediterranean populations of the semi-terrestrial beachflea Orchestia montagui using mitochondrial (cytochrome oxidase subunit I), microsatellite (eight loci) and allozymic data. The species typically forms large populations within heaps of dead seagrass leaves stranded on beaches at the waterfront. We adopted a hierarchical geographic sampling to unravel population structure in a species living at the sea-land transition and, hence, likely subjected to dramatically contrasting forces. Results: Mitochondrial DNA showed historical phylogeographic breaks among Adriatic, Ionian and the remaining basins (Tyrrhenian, Western and Eastern Mediterranean Sea) likely caused by the geological and climatic changes of the Pleistocene. Microsatellites (and to a lesser extent allozymes) detected a further subdivision between and within the Western Mediterranean and the Tyrrhenian Sea due to present-day processes. A pattern of isolation by distance was not detected in any of the analyzed data set. Conclusions: We conclude that the population structure of O. montagui is the result of the interplay of two contrasting forces that act on the species population genetic structure. On one hand, the species semi-terrestrial life style would tend to determine the onset of local differences. On the other hand, these differences are partially counter-balanced by passive movements of migrants via rafting on heaps of dead seagrass leaves across sites by sea surface currents. Approximate Bayesian Computations support dispersal at sea as prevalent over terrestrial regionalism.},
