This article takes up the questions of what determines whether a treaty provision is successfully changed and why provisions are renegotiated at subsequent Intergovernmental Conferences. The article presents an institutionalist theory explaining success and renegotiation and tests the theory using all core institutional provisions by means of Qualitative Comparative Analysis. The causal analysis shows that low conflict potential of an issue is sufficient for successfully changing the treaties. Furthermore, high conflict potential of an issue and its fundamental change are sufficient for it to be renegotiated.

These trends are already detectable over the historic period. Hence, it is beneficial to forecast seasonal droughts well in advance so that water managers and stakeholders can prepare to mitigate deleterious impacts. We developed a new cluster-based empirical forecast method to predict precipitation anomalies in winter. This algorithm considers not only the strength but also the pattern of the precursors. We compare our algorithm with dynamic forecast models and a canonical correlation analysis-based prediction method demonstrating that our prediction method performs better in terms of time and pattern correlation in the Mediterranean and European regions.

They have been developed by a broad range of actors, such as cities, non-profit organizations, and private corporations. Several scholars have lately devoted particular attention to voluntary global business initiatives in the policy domain of climate change. Their studies have provided considerable insights into the role and function of such new modes of climate governance. However, the precise nature of the relationship between the various climate governance experiments and the international climate negotiations has not been analyzed in enough detail. Against this backdrop, the present article explores the interplay of a business sector climate governance experiment, i.e. the Greenhouse Gas Protocol (GHG Protocol) with the international climate regime. On the one hand, the article underscores that the GHG Protocol has filled a regulatory gap in global climate policy-making by providing the means for the corporate sector to comprehensively account and report their GHGs. On the other hand, it reveals that the application of the GHG Protocol guidelines depends to a large extent on the existence of an overarching policy framework set up by nation-states at the intergovernmental level. Only if private companies receive a clear political signal that stringent mandatory GHG emission controls and a global market-based instrument are at least likely to be adopted will they put substantial efforts into the accurate measurement and management of their GHGs. Thus, this article points to the limits of climate governance experimentation and suggests that business sector climate governance experiments need to be embedded in a coherent international regulatory setting which generates a clear stimulus for corporate action.

Here, we present a new moment-based approach to classify the shape of observed biomass-weighted trait distributions into normal, peaked, skewed, or bimodal that facilitates spatio-temporal and cross-system comparisons. Our observed phytoplankton trait distributions exhibited substantial variance and were mostly skewed or bimodal rather than normal. Additionally, mean, variance, skewness und kurtosis were strongly correlated. This is in conflict with trait-based aggregate models that often assume normally distributed trait values and small variances. Given these discrepancies between our data and general model assumptions we used the observed trait distributions to test how well different aggregate models with first- or second-order approximations and different types of moment closure predict the biomass, mean trait, and trait variance dynamics using weakly or moderately nonlinear fitness functions. For weakly non-linear fitness functions aggregate models with a second-order approximation and a data-based moment closure that relied on the observed correlations between skewness and mean, and kurtosis and variance predicted biomass and often also mean trait changes fairly well and better than models with first-order approximations or a normal-based moment closure. In contrast, none of the models reflected the changes of the trait variances reliably. Aggregate model performance was often also poor for moderately nonlinear fitness functions. This questions a general applicability of the normal-based approach, in particular for predicting variance dynamics determining the speed of trait changes and maintenance of biodiversity. We evaluate in detail how and why better approximations can be obtained.

MethodsWith eye-movement recording, children and adults viewed sentences with either identical, orthographically similar, homophonic or unrelated substitutions of the first characters in target words. To the extent that readers rely on orthographic or phonological cues, substitutions that contain such cues should cause less disruption reading than do unrelated substitutions. ResultsOn pretarget words, there was a reliable reduction in gaze duration due to homophonic substitution only for children. On target words, we observed reliable recovery effects due to orthographic similarity for adults. On post-target words, adults had better orthographic-based and phonological-based recovery abilities than children. ConclusionsThe combination of eye movement recording and the error detection paradigm offers a novel implicit paradigm for studying reading development: during sentence reading, beginning readers of Chinese may rely on phonological mediation, while skilled readers have more direct access to semantics from orthography.

T1 - EEG Source Imaging Indices of Cognitive Control Show Associations with Dopamine System Genes JF - Brain Topography N2 - Cognitive or executive control is a critical mental ability, an important marker of mental illness, and among the most heritable of neurocognitive traits. Two candidate genes, catechol-O-methyltransferase (COMT) and DRD4, which both have a roles in the regulation of cortical dopamine, have been consistently associated with cognitive control. Here, we predicted that individuals with the COMT Met/Met allele would show improved response execution and inhibition as indexed by event-related potentials in a Go/NoGo task, while individuals with the DRD4 7-repeat allele would show impaired brain activity. We used independent component analysis (ICA) to separate brain source processes contributing to high-density EEG scalp signals recorded during the task. As expected, individuals with the DRD4 7-repeat polymorphism had reduced parietal P3 source and scalp responses to response (Go) compared to those without the 7-repeat. Contrary to our expectation, the COMT homozygous Met allele was associated with a smaller frontal P3 source and scalp response to response-inhibition (NoGo) stimuli, suggesting that while more dopamine in frontal cortical areas has advantages in some tasks, it may also compromise response inhibition function. An interaction effect emerged for P3 source responses to Go stimuli. These were reduced in those with both the 7-repeat DRD4 allele and either the COMT Val/Val or the Met/Met homozygous polymorphisms but not in those with the heterozygous Val/Met polymorphism. This epistatic interaction between DRD4 and COMT replicates findings that too little or too much dopamine impairs cognitive control. The anatomic and functional separated maximally independent cortical EEG sources proved more informative than scalp channel measures for genetic studies of brain function and thus better elucidate the complex mechanisms in psychiatric illness.

T1 - The Chelyabinsk meteorite BT - new insights from a comprehensive electron microscopy and Raman spectroscopy study with evidence for graphite in olivine of ordinary chondrites JF - Meteoritics & planetary science : journal of the Meteoritical Society N2 - We present results of petrographic, mineralogical, and chemical investigations of three Chelyabinsk meteorite fragments. Three distinct lithologies were identified: light S3LL5, dark S4-S5LL5 material, and opaque fine-grained former impact melt. Olivine-spinel thermometry revealed an equilibration temperature of 703 +/- 23 degrees C for the light lithology. All plagioclase seems to be secondary, showing neither shock-induced fractures nor sulfide-metal veinlets. Feldspathic glass can be observed showing features of extensive melting and, in the dark lithology, as maskelynite, lacking melt features and retaining grain boundaries of former plagioclase. Olivine of the dark lithology shows planar deformation features. Impact melt is dominated by Mg-rich olivine and resembles whole-rock melt. Melt veins (<2mm) are connected to narrower veinlets. Melt vein textures are similar to pegmatite textures showing chilled margins, a zone of inward-grown elongated crystals and central vugs, suggesting crystallization from supercooled melt. Sulfide-metal droplets indicate liquid immiscibility of both silicate and sulfide as well as sulfide and metal melts. Impact melting may have been an important factor for differentiation of primitive planetary bodies. Graphite associated with micrometer-sized melt inclusions in primary olivine was detected by Raman mapping. Carbon isotopic studies of graphite could be applied to test a possible presolar origin.

A1 - Wittmann, Hella A1 - Spiegel, Cornelia T1 - Coupling erosion and topographic development in the rainiest place on Earth BT - Reconstructing the Shillong Plateau uplift history with in-situ cosmogenic Be-10 JF - Earth & planetary science letters N2 - The uplift of the Shillong Plateau, in northeast India between the Bengal floodplain and the Himalaya Mountains, has had a significant impact on regional precipitation patterns, strain partitioning, and the path of the Brahmaputra River. Today, the plateau receives the highest measured yearly rainfall in the world and is tectonically active, having hosted one of the strongest intra-plate earthquakes ever recorded. Despite the unique tectonic and climatic setting of this prominent landscape feature, its exhumation and surface uplift history are poorly constrained. We collected 14 detrital river sand and 3 bedrock samples from the southern margin of the Shillong Plateau to measure erosion rates using the terrestrial cosmogenic nuclide 10Be. The calculated bedrock erosion rates range from 2.0 to 5.6 m My−1, whereas catchment average erosion rates from detrital river sands range from 48 to 214 m My−1. These rates are surprisingly low in the context of steep, tectonically active slopes and extreme rainfall. Moreover, the highest among these rates, which occur on the low-relief plateau surface, appear to have been affected by anthropogenic land-use change. To determine the onset of surface uplift, we coupled the catchment averaged erosion rates with topographic analyses of the plateau's southern margin. We interpolated an inclined, pre-incision surface from minimally eroded remnants along the valley interfluves and calculated the eroded volume of the valleys carved beneath the surface. The missing volume was then divided by the volume flux derived from the erosion rates to obtain the onset of uplift. The results of this calculation, ranging from 3.0 to 5.0 Ma for individual valleys, are in agreement with several lines of stratigraphic evidence from the Brahmaputra and Bengal basin that constrain the onset of topographic uplift, specifically the onset of flexural loading and the transgression from deltaic to marine deposition. Ultimately, our data corroborate the hypothesis that surface uplift was decoupled from the onset of rapid exhumation, which occurred several millions of years earlier.

This accounts in particular for the ecosystem respiration (R-eco) and its components, the autotrophic (R-a) and heterotrophic respiration (R-h) which vary tremendously in time and space. This study presents a method to separate R-eco into R-a [as the sum of R-a (shoot) and R-a (root)] and R-h in order to detect temporal and small-scale spatial dynamics within their relative contribution to overall R-eco. Thus, predominant environmental drivers and underlying mechanisms can be revealed. R-eco was derived during nighttime by automatic chamber CO2 flux measurements on plant covered plots. R-h was derived from CO2 efflux measurements, which were performed in parallel to R-eco measurements on a fallow plot using CO2 sampling tubes in 10 cm soil depth. R-a (root) was calculated as the difference between sampling tube CO2 efflux measurements on a plant covered plot and R-h. R-a (shoot) was calculated as R-eco - R-a (root) - R-h. Measurements were carried out for winter wheat (Triticum aestivum L.) during the crop season 2015 at an experimental plot located in the hummocky ground moraine landscape of NE Germany. R-eco varied seasonally from < 1 to 9.5 g C m(-2) d(-1), and was higher in adult (a) and reproductive (r) than juvenile (j) stands (gC m(-2) d(-1): j = 1.2, a = 4.6, r = 5.3). Observed R-a and R-h were in general smaller compared to the independently measured R-eco, contributing in average 58% and 42% to R-eco. However, both varied strongly regarding their environmental drivers and particular contribution throughout the study period, following the seasonal development of soil temperature and moisture (R-h) as well as crop development (R-a). Thus, our results consistently revealed temporal dynamics regarding the relative contribution of R-a (root) and R-a (shoot) to R-a, as well as of R-a and R-h to R-eco. Based on the observed results, implications for partitioning of R-eco in croplands are given.

Erbsen und Ackerbohnen spielen als Fett- und FS-Quelle praktisch keine Rolle. Sojabohnen sind eine wesentliche Quelle für Linolsäure, die häufigste n-6-FS. An zweiter Stelle steht die Ölsäure. Aber auch der Gehalt an der n-3-FS α-Linolensäure (ALA) ist hoch, womit sich Sojaöl in die Reihe der Fette mit mittlerem ALA-Gehalt, wie Raps- und Walnussöl einreiht. Im Gegensatz zu Rapsöl entspricht jedoch das Linolsäure/α-Linolensäure- Verhältnis nicht dem empfohlenen Verhältnis von 5:1 in der Gesamt- Diät [13]. Zum Ausgleich für die Fette aus der übrigen Nahrung (Getreide, Lebensmittel tierischer Herkunft) sollten Pflanzenöle besser noch ein engeres Verhältnis als 5:1 aufweisen.

Peas and faba beans provide almost no fats. Soybeans are a good source of linoleic acid, the most common n-6 fatty acid followed by oleic acid. However, the level of the n-3 fatty acid α-linolenic acid (ALA) is also high, which puts soybean oil in the category of fats with medium ALA content, along with oils such as rapeseed oil and walnut oil. However, unlike rapeseed oil, the ratio of linoleic acid to α-linolenic acid is not the recommended ratio for the overall diet of 5:1 [13]. In order to balance out the fats from the rest of the diet (cereals, foods of animal origin), vegetable oils should ideally have a ratio even better than 5:1. Lupine oil has such a ratio, although its absolute ALA content is rather low.

T1 - Metabolite and transcript markers for the prediction of potato drought tolerance JF - Plant Biotechnology Journal N2 - Potato (Solanum tuberosum L.) is one of the most important food crops worldwide. Current potato varieties are highly susceptible to drought stress. In view of global climate change, selection of cultivars with improved drought tolerance and high yield potential is of paramount importance. Drought tolerance breeding of potato is currently based on direct selection according to yield and phenotypic traits and requires multiple trials under drought conditions. Marker-assisted selection (MAS) is cheaper, faster and reduces classification errors caused by noncontrolled environmental effects. We analysed 31 potato cultivars grown under optimal and reduced water supply in six independent field trials. Drought tolerance was determined as tuber starch yield. Leaf samples from young plants were screened for preselected transcript and nontargeted metabolite abundance using qRT-PCR and GC-MS profiling, respectively. Transcript marker candidates were selected from a published RNA-Seq data set. A Random Forest machine learning approach extracted metabolite and transcript markers for drought tolerance prediction with low error rates of 6% and 9%, respectively. Moreover, by combining transcript and metabolite markers, the prediction error was reduced to 4.3%. Feature selection from Random Forest models allowed model minimization, yielding a minimal combination of only 20 metabolite and transcript markers that were successfully tested for their reproducibility in 16 independent agronomic field trials. We demonstrate that a minimum combination of transcript and metabolite markers sampled at early cultivation stages predicts potato yield stability under drought largely independent of seasonal and regional agronomic conditions.

Als Haupttransmissionsweg gilt die frühe Mutter-Kind-Interaktion. Über die langfristigen Auswirkungen auf die Kinder im Erwachsenenalter und die Rolle der Interaktion liegen kaum Ergebnisse vor. Im Rahmen der Mannheimer Risikokinderstudie wurden postpartale Depressionen bis zwei Jahre nach der Geburt erfasst. Die kindliche Entwicklung wurde fortlaufend und die Mutter-Kind-Interaktion im Alter von 3 Monaten standardisiert erhoben. 28 Kinder postpartal depressiver und 107 Kinder gesunder Mütter konnten mit 25 Jahren untersucht werden. Beeinträchtigungen der kognitiven und psychischen Entwicklung bei Kindern postpartal depressiver Mütter waren bis ins Erwachsenenalter nachweisbar. Responsives bzw. sensitives mütterliches Verhalten wirkte der negativen Entwicklung entgegen. Dies betont die Bedeutung einer hohen Qualität der Mutter-Kind-Interaktion für die Entwicklung von Risikokindern. N2 - Postpartum depression (PPD) is a common and serious mental health problem with prevalence rates ranging from 13% to 19%, and is associated with an increased risk of adverse child development. PPD is characterized by symptoms common of depression, particularly by impairments of maternity, parenting, and mother-infant interactions. Several reviews suggest an impact on attachment, cognitive, behavioral, and health-related outcome in the offspring. However, the long-term effects of PPD regarding cognitive and mental development into adulthood and the underlying mechanisms, especially the role of maternal interactional behavior, are not yet well understood. In the Mannheim Study of Children at Risk, maternal depression was assessed when the child was 3 months and 2 years old. Development from infancy to young adulthood (25 years) was assessed at regular intervals in 28 children of postnatally depressed mothers and 107 children born to mentally healthy mothers. Cognitive outcome up to age 11 was measured using standardized instruments; in adulthood, school outcome was used approximately. Psychiatric diagnosis as well as symptom scores served as psychological outcome. At age 3 months, mothers and infants were videotaped during a nursing and a playing situation. Videotapes of the 10-min session were recorded and evaluated by trained raters (kappa > .83) using the Category System for Microanalysis of Early Mother Child Interaction (Esser, Scheven, et al., 1989). The cognitive as well as social-emotional outcome of children of mothers suffering from PPD was significantly poorer than in the children of mentally healthy mothers. The adverse effects were more pronounced during childhood. The offspring of postnatally depressed mothers who interacted in a responsive manner with their infant exhibited a better prognosis in contrast to those with mothers interacting less sensitively. This effect was observed with regard to cognitive development and symptoms of externalizing behavior at age 19 years. Regarding internalizing behavior, no impact of maternal behavior was detected. These findings emphasize the importance of high-quality early mother-child interaction in the development of children at risk.

The PPD treatment should always comprise treatment of depression as well as treatment of the disturbed mother-child interaction.

BT - Is there a protective effect of maternal responsiveness? JF - Kindheit und Entwicklung N2 - In einer prospektiven Längsschnittstudie wurde der Zusammenhang zwischen früher Responsivität der Mutter und kognitiver Entwicklung ihrer früh- bzw. reifgeborenen Kinder untersucht. Im Alter von drei Monaten wurde dafür die Mutter-Kind-Interaktion mittels Verhaltensbeobachtung erfasst. Bei n=351 der teilnehmenden Kinder (101 frühgeboren) wurde die allgemeine Intelligenz (IQ) im Alter von 11 Jahren und bei n=313 (85 frühgeboren) zusätzlich der höchste erreichte Schulabschluss bis 25 Jahren erhoben. Frühgeborene wiesen mit 11 Jahren einen signifikant niedrigeren IQ als Reifgeborene auf, nachdem für mögliche konfundierende Faktoren kontrolliert worden war. Nur bei Früh-, nicht aber bei Reifgeborenen zeigte sich ein signifikanter positiver Zusammenhang zwischen mütterlicher Responsivität und IQ. Für die Wahrscheinlichkeit einen höheren Schulabschluss (mind. Fachabitur) zu erreichen, fand sich weder ein signifikanter Effekt von Frühgeburtlichkeit noch von mütterlicher Responsivität. N2 - Preterm birth is associated with adverse long-term consequences regarding cognitive development. Whereas children born very preterm represent a subgroup at special risk, so-called late preterms are also affected to a lesser degree. Effects of prematurity can be observed until adulthood. For example, decreased wealth was reported in adults born preterm, which was mediated by decreased intelligence during childhood and lower educational qualifications during young adulthood. Hence, it is highly relevant to examine whether certain factors can buffer against the adverse effects of preterm birth on cognitive development. Parenting might play an important role here. There is evidence suggesting a protective effect of sensitive parenting during childhood on later cognitive outcome in preterms. In the current study, we examined whether early responsive maternal care was associated with later intelligence and academic achievement in children born preterm versus full term. As part of an ongoing cohort study, early maternal responsiveness was assessed at the child’s age of 3 months (adjusted for gestational age) during a nursing and playing situation. At age 11 years, general intelligence (IQ) was determined in n = 351 children (101 born preterm; 168 male). Until age 25 years, educational qualification was assessed in n = 313 participants (85 born preterm; 145 male). IQ at age 11 was significantly lower in preterms compared with full-term subjects after adjusting for potential confounders like maternal educational background and early psychosocial risk. A significant interaction between preterm birth and early maternal responsiveness was detected. In preterms only, higher levels of early maternal responsiveness were significantly associated with higher child IQ. Lower IQs in children born preterm as compared with those born full term were observed in the subaverage-to-average range of maternal responsiveness. Interestingly, preterms exposed to very high levels of maternal responsiveness showed slightly higher IQs when compared with children born at term. With regard to academic achievement, neither a significant effect of preterm birth nor of early maternal responsiveness occurred after adjusting for potential confounders. The results of the current study replicate and extend earlier findings with regard to a protective effect of sensitive parenting on childhood cognitive outcome in preterms. The lacking impact of prematurity on academic achievement may be explained by the exclusion of participants with IQs outside the normal range in the current study. Interventions enhancing early responsive care in parents of preterms may be advisable. More studies on long-term outcomes of such interventions on cognitive development are encouraged.

Adult participants gave keyboarded responses in their first language under controlled experimental conditions (N = 1,274, with subsamples responding in Bulgarian, Dutch, English, Finnish, French, German, Greek, Icelandic, Italian, Norwegian, Portuguese, Russian, Spanish, and Swedish). We measured the time to initiate a response (RT) and interkeypress intervals, and calculated measures of name and spelling agreement. There was a tendency across all languages for quicker RTs to pictures with higher familiarity, image agreement, and name frequency, and with higher name agreement. Effects of spelling agreement and effects on output rates after writing onset were present in some, but not all, languages. Written naming therefore shows name retrieval effects that are similar to those found in speech, but our findings suggest the need for cross-language comparisons as we seek to understand the orthographic retrieval and/or assembly processes that are specific to written output.

Here, we investigated the mechanism of the AAA(+) protein Rubisco activase (Rca) in metabolic repair of the photosynthetic enzyme Rubisco, a complex of eight large (RbcL) and eight small (RbcS) subunits containing eight catalytic sites. Rubisco is prone to inhibition by tight-binding sugar phosphates, whose removal is catalyzed by Rca. We engineered a stable Rca hexamer ring and analyzed its functional interaction with Rubisco. Hydrogen/deuterium exchange and chemical crosslinking showed that Rca structurally destabilizes elements of the Rubisco active site with remarkable selectivity. Cryo-electron microscopy revealed that Rca docks onto Rubisco over one active site at a time, positioning the C-terminal strand of RbcL, which stabilizes the catalytic center, for access to the Rca hexamer pore. The pulling force of Rca is fine-tuned to avoid global destabilization and allow for precise enzyme repair.

ART aims to explain and predict behavior in situations in which people either remain in a state of physical inactivity or initiate action (exercise). It is a dual-process model and assumes that exercise-related stimuli trigger automatic associations and a resulting automatic affective valuation of exercise (type-1 process). The automatic affective valuation forms the basis for the reflective evaluation (type-2 process), which can follow if self-control resources are available. The automatic affective valuation is connected with an action impulse, whereas the reflective evaluation can result in action plans. The two processes, in constant interaction, direct the individual towards or away from changing behavior. The ART of physical inactivity and exercise predicts that, when there is an affective-reflective discrepancy and self-control resources are low, behavior is more likely to be governed by the affective type-1 process. This introductory article explains the underlying concepts and main theoretical roots from which the ART of physical inactivity and exercise was developed (field theory, affective responses to exercise, automatic evaluation, evaluation-behavior link, dual-process theorizing). We also summarize the empirical tests that have been conducted to refine the theory in its present form.

T1 - Neighbourhood effects on plant reproduction BT - an experimental-analytical framework and its application to the invasive Senecio inaequidens JF - The journal of ecology N2 - Density dependence is of fundamental importance for population and range dynamics. Density-dependent reproduction of plants arises from competitive and facilitative plant-plant interactions that can be pollination independent or pollination mediated. In small and sparse populations, conspecific density dependence often turns from negative to positive and causes Allee effects. Reproduction may also increase with heterospecific density (community-level Allee effect), but the underlying mechanisms are poorly understood and the consequences for community dynamics can be complex. Allee effects have crucial consequences for the conservation of declining species, but also the dynamics of range edge populations. In invasive species, Allee effects may slow or stop range expansion. Observational studies in natural plant communities cannot distinguish whether reproduction is limited by pollination-mediated interactions among plants or by other neighbourhood effects (e.g. competition for abiotic resources). Even experimental pollen supply cannot distinguish whether variation in reproduction is caused by direct density effects or by plant traits correlated with density. Finally, it is unknown over which spatial scales pollination-mediated interactions occur. To circumvent these problems, we introduce a comprehensive experimental and analytical framework which simultaneously (1) manipulates pollen availability and quality by hand pollination and pollinator exclusion, (2) manipulates neighbourhoods by transplanting target plants, and (3) analyses the effects of con- and heterospecific neighbourhoods on reproduction with spatially explicit trait-based neighbourhood models. Synthesis. By manipulating both pollen availability and target plant locations within neighbourhoods, we can comprehensively analyse spatially explicit density dependence of plant reproduction. This experimental approach enhances our ability to understand the dynamics of sparse populations and of species geographical ranges.

Estimates of the spherical harmonic Gauss coefficients of the core field secular variation were then derived by applying a correlation based modelling. Finally, a Fourier transform was applied to the time series of the Gauss coefficients. This process led to reliable temporal spectra of the Gauss coefficients up to spherical harmonic degree 5 or 6, and down to periods as short as 1 or 2 years depending on the coefficient. We observed that a k(-2) slope, where k is the frequency, is an acceptable approximation for these spectra, with possibly an exception for the dipole field. The monthly estimates of the core field secular variation at the observatory sites also show that large and rapid variations of the latter happen. This is an indication that geomagnetic jerks are frequent phenomena and that significant secular variation signals at short time scales - i.e. less than 2 years, could still be extracted from data to reveal an unexplored part of the core dynamics.

Recently, research on EU institutions devotes increasing attention to analyzing structures and procedures of decision-making in EU institutions, most notably the EU Commission. Conventionally, the EU Commission is portrayed as a fragmented organization, divided along the lines of staff nationality, sectoral responsibilities and cabinets and General Directorates (DGs). The Secretariat General has long been viewed a weak actor that is hardly able or motivated to steer internal decision-making. However, recent research indicates a changing role of the Secretariat General as a pro-active broker and last arbiter. This article studies how the Secretariat General is perceived by the DGs in policy coordination and argues that this perception depends on the pattern of political authority, bureaucratic roles and the relevance and the alternatives prevailing in the policy field. The article is based on data from a survey among Commission officials.

N2 - The talk contained in this contribution was held at the 31st MPK in Heidelberg in 2015. It deals with research on motivation done in the 1970s in Bochum by Heinz Heckhausen and his colleagues ("Bochum Research Group"). Heckhausen and each member of the group are shortly characterized through their individual work focus. The working atmosphere created in this group was highly cooperative and stimulating. In the second part, the speech deals with the topics the author worked on and how this research developed from the ideas of the Bochum group. These topics are reference norm orientation, single-case analysis of learning motivation, activity-related (vs. purpose-related) incentives, flow experience, and the investigation of the specific influences that different kinds of motivation have on self-regulated learning.

Potential factors in its success are temperature, light and nutrient levels. Grazing losses through zooplankton have been measured in the laboratory but are typically not regarded as a factor in (failed) invasion success. In some potentially suitable lakes, C. raciborskii has never been found, although it is present in water bodies close by. Therefore, we tested the invasive potential of three different isolates introduced into natural plankton communities using laboratory mesocosm experiments under three grazing levels: ambient zooplankton densities, removal of large species using 100 mu m mesh and a ca. doubling of large species. Three C. raciborskii isolates originating from the same geographic region (North-East Germany) were added separately to the four replicates of each treatment and kept in semi-continuous cultures for 21 days. Two isolates disappeared from the mesocosms and were also not viable in filtered lake water indicating that the lake water itself or the switch from culture medium to lake water led to the decay of the inoculated C. raciborskii. Only one out of the three isolates persisted in the plankton communities at a rather low level and only in the treatment without larger zooplankton. This result demonstrates that under potentially suitable environmental conditions, top-down control from zooplankton might hamper the establishment of C. raciborskii. Non-metric multidimensional scaling showed distinct variation in resident phytoplankton communities between the different grazing levels, thus differential grazing impact shaped the resident community in different ways allowing C. raciborskii only to invade under competitive (= low grazing pressure) conditions. Furthermore, even after invasion failure, the temporary presence of C. raciborskii influenced the phytoplankton community.

In the present study, we investigated the distribution and stand characteristics of the two key brackish marsh species Bolboschoenus maritimus and Phragmites australis in the Elbe estuary together with several abiotic habitat factors. We then tested the effect of these habitat factors on plant growth and zonation with generalised linear models (GLMs). Our study provides detailed information on the importance of single habitat factors and their interactions for controlling the distribution patterns and stand characteristics of two key marsh species. Our results suggest that flow velocity is the main factor influencing species distribution and stand characteristics and together with soil-water salinity even affects the inundation tolerance of the two specie investigated here. Additionally, inundation height and duration as well as interspecific competition helped explain the distribution patterns and stand characteristics. By identifying the drivers of marsh zonation and stand characteristics and quantifying their effects, this study provides useful information for evaluating a future contribution of tidal marsh vegetation to ecosystem-based shore protection.

This is particularly evident in the policy domain of climate change, where a number of authors have observed a relocation of authority in global climate governance. These scholars claim that multilateral treaty making has lost much of its spark, and they emphasize the emergence of transnational governance arrangements, such as city networks, private certification schemes, and business self-regulation. However, the different types of interactions between the various transnational climate initiatives and the intergovernmental level have not been studied in much detail and only recently attracted growing scholarly interest. Therefore, the present article addresses this issue and focuses on the interplay between three different transnational climate governance arrangements and the international climate regime. The analysis in this article underscores that substate and nonstate actors have attained several authoritative functions in global climate policy making. Nevertheless, the three case studies also demonstrate that this development does not imply that we are witnessing a general shift of authority away from the intergovernmental level toward transnational actors. Instead, what can be observed in global climate governance is an ongoing reconfiguration of authority, which apparently reaffirms the centrality of the international climate regime. Thus, this article points to the need for a more nuanced perspective on the changing patterns of authority in global climate governance. In a nutshell, this study shows that the international climate regime is not the only location where the problem of climate change is addressed, while it highlights the persistent authority of state-based forms of regulation.

Specifically, we show that for skewed and bimodal distributions many or even most cases will show a regression effect that is in expectation away from the mean, or that is not just towards but actually beyond the mean. We illustrate our results in quantitative detail with typical examples from experimental and biometric applications, which exhibit a clear regression away from the mean (‘egression from the mean’) signature.

Activation of SnRK1 leads to the down-regulation of ATP-consuming biosynthetic processes and the stimulation of energy-generating catabolic reactions by transcriptional reprogramming and posttranslational modifications. Although considerable progress has been made during the last years in understanding the SnRK1 signaling pathway, many of its components remain unidentified. Here, we show that the catalytic alpha-subunits KIN10 and KIN11 of the Arabidopsis (Arabidopsis thaliana) SnRK1 complex interact with the STOREKEEPER RELATED1/G-Element Binding Protein (STKR1) inside the plant cell nucleus. Overexpression of STKR1 in transgenic Arabidopsis plants led to reduced growth, a delay in flowering, and strongly attenuated senescence. Metabolite profiling revealed that the transgenic lines exhausted their carbohydrates during the dark period to a greater extent than the wild type and accumulated a range of amino acids. At the global transcriptome level, genes affected by STKR1 overexpression were broadly associated with systemic acquired resistance, and transgenic plants showed enhanced resistance toward a virulent strain of the biotrophic oomycete pathogen Hyaloperonospora arabidopsidis Noco2. We discuss a possible connection of STKR1 function, SnRK1 signaling, and plant immunity.

This research has considerably improved our understanding of the local level in the global response to climate change. The present article synthesizes the literature on local climate policies with respect to the 1.5 degrees C target. While most studies have focused on pioneering cities and networks, we contend that the broader impacts of local climate actions and their relationship to regional, national, and international policy frameworks have not been studied in enough detail. Against this backdrop, we introduce the concept of upscaling and contend that local climate initiatives must go hand in hand with higher-level policies and be better integrated into the multi-level governance system.

It is also known that some B-type stars have spots on their surface. Yet up to now no X-ray activity associated with spots on early-type stars was detected. In this Letter we report the detection of a magnetic field on the B2V star rho Oph A. Previously, we assessed that the X-ray activity of this star is associated with a surface spot, herewith we establish its magnetic origin. We analyze spectra of rho Oph A obtained with the FORS2 spectrograph at ESO Very Large Telescope (VLT) at two epochs, and detect a longitudinal component of the magnetic field of the order of similar to 500 G in one of the datasets. The detection of the magnetic field only at one epoch can be explained by stellar rotation which is also invoked to explain observed periodic X-ray activity. From archival HARPS ESO VLT high resolution spectra we derived the fundamental stellar parameters of rho Oph A and further constrained its age. We conclude that rho Oph A provides strong evidence for the presence of active X-ray emitting regions on young magnetized early type stars.

BT - Why consumers make economically (non-)sustainable consumption choices JF - Journal of Cleaner Production N2 - Although ecologically and socially responsible consumption helps to reduce the harmful effects of resource use for both nature and society, all types of consumption (whether green or fair) deplete valuable resources. At the same time, to maintain household financial sustainability, spending should not exceed a household's financial resources. Thus, economically sustainable consumption is related to the consumer's decision to not buy products and the disposition to forgo specific purchases. Based on a means-end chain approach, this study investigates consumer cognitive decision-making structures related to six distinct options for economically (non-)sustainable consumption. Whereas saving motives, waste concerns, and avoidance motivations support economically sustainable decisions, economically non-sustainable decision-making is directly linked to attaining overall life goals. By clustering respondents based on the elicited means-end chains, the study discloses four consumer groups with distinctive motivational structures. The study also reveals several obstacles to promoting economic sustainability, indicates methods to overcome such obstacles, and suggests avenues for future research.

Eine besondere Rolle kommt dabei positiven frühen Eltern-Kind-Beziehungen zu (sowohl Mutter- als auch Vater-Kind-Interaktionen). Daneben spielen auch Interaktionserfahrungen im Alter von zwei Jahren des Kindes eine bedeutsame Rolle; diese schützen Risikokinder davor, eine ungünstige Entwicklung zu nehmen und tragen dazu bei, dass sich Kinder, die in psychosozialen Hochrisikofamilien aufwachsen, trotz ungünstiger „Startbedingungen“ positiv entwickeln. Neben Merkmalen der sozialen Umwelt nehmen auch sprachliche, sozial-emotionale und internale Kompetenzen des Kindes im Entwicklungsverlauf eine wichtige Rolle ein. Diese Kompetenzen ermöglichen es Risikokindern auch unter widrigen Lebensumständen (psychosoziale Hochrisikofamilien, Aufwachsen in Armutsverhältnissen) erfolgreich zu bestehen. Darüber hinaus zeigt die Arbeit, dass Resilienz ein Persönlichkeitsmerkmal ist, das ab dem frühen Erwachsenenalter eine hohe Stabilität besitzt. Mit diesen Befunden verweist die Arbeit auf die große Bedeutung der Resilienz bei der Vorhersage der langfristigen Entwicklung von Risikokindern. N2 - Resilience refers to the ability to successfully deal with stressful life circumstances and experiences and to cope with them. Based on data from the Mannheim Study of Children at Risk, which follows a sample of children at risk from birth to adulthood, the present paper provides convincing evidence demonstrating how protective factors in the child and his/her family environment operate during the course of development to contribute to the development of resilience. As shown, a major role is assigned to positive early parent–child relationships (both mother– and father–child interactions). Moreover, positive interactive experiences at the child’s age of 2 years play a significant role. These experiences consistently contribute to a positive child development in the face of adversity. In addition to characteristics of the social environment of the child, cognitive, social–emotional, and internal competencies during childhood, youth, and young adulthood play a major role in the development of resilience. These competencies enable children at risk who are growing up in psychosocial high-risk families or in poverty to successfully cope with conditions of high adversity. Moreover, the findings presented here demonstrate that resilience may be conceived as a personal characteristic that exhibits high stability since young adulthood. With these findings, the present study points to the significance of resilience in predicting the long-term outcome of children at risk.

The gene expression of inflammatory cytokines and TRP channels was measured in human disc samples obtained from patients undergoing discectomy at the cervical (n = 24) or lumbar (n = 27) spine for degenerative disc disease (DDD) and disc herniation (DH) and analyzed for differences with regard to spinal level, IVD degeneration grade, Modic grade, age, sex, disc region and surgical extent. Aside from genes with known implication in DDD and DH, four previously unreported genes from the interferon and TRP families (IFNA1, IFNA8, IFNB1, TRPC6) could be detected. A correlation between gene expression and age (IL-15) and IVD degeneration grade (IFNA1, IL-6, IL-15, TRPC6), but not Modic grade, was identified. Significant differences were detected between cervical and lumbar discs (IL-15), nucleus and annulus (IL-6, TNF-alpha, TRPC6), single-level and multi-level surgery (IL-6, IL-8) as well as DDD and DH (IL-8), while sex had no effect. Multiple gene-gene pair correlations, either between different cytokines or between cytokines and TRP channels, exist in the disc. This study supports the relevance of IL-6 and IL-8 in disc diseases, but furthermore points toward a possible pathological role of IL-15 and type I interferons, as well as a mechanistic role of TRPC6. With limited differences in the inflammatory profile of cervical and lumbar discs, novel anti-inflammatory or TRP-modulatory strategies for the treatment of disc pathologies may be applicable independent of the spinal region.

The impact of a major merger JF - Monthly notices of the Royal Astronomical Society N2 - Galaxies are surrounded by sizeable gas reservoirs which host a significant amount of metals: the circum-galactic medium (CGM). The CGM acts as a mediator between the galaxy and the extragalactic medium. However, our understanding of how galaxy mergers, a major evolutionary transformation, impact the CGM remains deficient. We present a theoretical study of the effect of galaxy mergers on the CGM. We use hydrodynamical cosmological zoom-in simulations of a major merger selected from the Illustris project such that the z = 0 descendant has a halo mass and stellar mass comparable to the Milky Way. To study the CGM we then re-simulated this system at a 40 times better mass resolution, and included detailed post-processing ionization modelling. Our work demonstrates the effect the merger has on the characteristic size of the CGM, its metallicity, and the predicted covering fraction of various commonly observed gas-phase species, such as H I, C IV, and O VI. We show that merger-induced outflows can increase the CGM metallicity by 0.2-0.3 dex within 0.5 Gyr post-merger. These effects last up to 6 Gyr post-merger. While the merger increases the total metal covering fractions by factors of 2-3, the covering fractions of commonly observed UV ions decrease due to the hard ionizing radiation from the active galactic nucleus, which we model explicitly. Our study of the single simulated major merger presented in this work demonstrates the significant impact that a galaxy interaction can have on the size, metallicity, and observed column densities of the CGM.

The climate and yield data used was for a period of 36 years between 1980 and 2015. Similar to the observed decrease (P < 0.001) in rice yield, pan evaporation, solar radiation, and wind speed declined significantly. Eight principal components exhibited an eigenvalue > 1 and explained 83.1% of the total variance of predictor variables. The SVM regression function using the scores of the first principal component explained about 75% of the variance in rice yield data and linear regression about 64%. SVM regression between annual solar radiation values and yield explained 67% of the variance. Only the first component of the principal component analysis (PCA) exhibited a clear long-term trend and sometimes short-term variance similar to that of rice yield. Short-term fluctuations of the scores of the PC1 are closely coupled to those of rice yield during the 1986-1993 and the 2006-2013 periods thereby revealing the inter-annual sensitivity of rice production to climate variability. Solar radiation stands out as the climate variable of highest influence on rice yield, and the influence was especially strong during monsoon and post-monsoon periods, which correspond to the vegetative, booting, flowering, and grain filling stages in the study area. The outcome is expected to provide more in-depth regional-specific climate-rice linkage for screening of better cultivars that can positively respond to future climate fluctuations as well as providing information that may help optimized planting dates for improved radiation use efficiency in the study area.

However, substantial disagreement has been found between informants. Specifically, children with attention-deficit/hyperactivity disorder (ADHD) tend to overestimate their competencies, also known as "positive (illusionary) bias." This study compared parent, teacher, and adolescent ratings of ADHD and other behavioral symptoms in a sample of 114 adolescents with ADHD. Further, the effect of cross-informant disagreement (CID) on treatment outcomes was investigated in a subsample of 54 adolescents who had undergone a training and coaching intervention. Overall, there was moderate agreement among informants. Parent and adolescent ratings were more strongly correlated with each other than with teacher ratings. The strongest discrepancy was found between teacher and adolescent ratings on prosocial behavior. This discrepancy explained 12% of the variance in parent-rated ADHD symptom severity after the intervention. The treatment was less effective in participants with high teacher-adolescent disagreement on prosocial behavior (d = 0.41) than with low disagreement (d = 0.98). These findings suggest that professionals working with adolescents with ADHD should consider multiple sources of information before initiating treatment and pay attention to cross-informant disagreements because these may indicate a risk of diminished treatment effects.

After distilling two major drivers we construct a future compass in order to conceive of four futures of relations between the EU and Ukraine. Our scenarios aim to challenge deep-rooted assumptions on the EU’s neighbourhood with Ukraine: How will the politico-economic challenges in the European countries influence the EU’s approach towards the East? Will more EU engagement in Ukraine contribute to enduring peace? Does peace always come with stability? Which prospects does the idea of Intermarium have? Are the pivotal transformation players in Ukraine indeed oligarchs or rather small- and medium-sized entrepreneurs? After presenting our scenarios, we propose indicators to know in the years to come, along which path future relations do develop. By unearthing surprising developments we hope to provoke innovative thoughts on Eastern Europe in times of post truth societies, confrontation between states and hybrid warfare.

In contrast, East Asia has so far received little attention, despite representing a core region at which the Neolithic transition took place independently similar to 3 millennia after its onset in the Near East. We report genome-wide data from two hunter-gatherers from Devil's Gate, an early Neolithic cave site (dated to similar to 7.7 thousand years ago) located in East Asia, on the border between Russia and Korea. Both of these individuals are genetically most similar to geographically close modern populations from the Amur Basin, all speaking Tungusic languages, and, in particular, to the Ulchi. The similarity to nearby modern populations and the low levels of additional genetic material in the Ulchi imply a high level of genetic continuity in this region during the Holocene, a pattern that markedly contrasts with that reported for Europe.

T1 - Combined hybridization capture and shotgun sequencing for ancient DNA analysis of extinct wild and domestic dromedary camel T2 - Postprints der Universität Potsdam Mathematisch-Naturwissenschaftliche Reihe N2 - The performance of hybridization capture combined with next-generation sequencing (NGS) has seen limited investigation with samples from hot and arid regions until now. We applied hybridization capture and shotgun sequencing to recover DNA sequences from bone specimens of ancient-domestic dromedary (Camelus dromedarius) and its extinct ancestor, the wild dromedary from Jordan, Syria, Turkey and the Arabian Peninsula, respectively. Our results show that hybridization capture increased the percentage of mitochondrial DNA (mtDNA) recovery by an average 187-fold and in some cases yielded virtually complete mitochondrial (mt) genomes at multifold coverage in a single capture experiment. Furthermore, we tested the effect of hybridization temperature and time by using a touchdown approach on a limited number of samples. We observed no significant difference in the number of unique dromedary mtDNA reads retrieved with the standard capture compared to the touchdown method. In total, we obtained 14 partial mitochondrial genomes from ancient-domestic dromedaries with 17-95% length coverage and 1.27-47.1-fold read depths for the covered regions. Using whole-genome shotgun sequencing, we successfully recovered endogenous dromedary nuclear DNA (nuDNA) from domestic and wild dromedary specimens with 1-1.06-fold read depths for covered regions. Our results highlight that despite recent methodological advances, obtaining ancient DNA (aDNA) from specimens recovered from hot, arid environments is still problematic. Hybridization protocols require specific optimization, and samples at the limit of DNA preservation need multiple replications of DNA extraction and hybridization capture as has been shown previously for Middle Pleistocene specimens.

A widely applied strategy in miRNA inhibition is the use of antisense agents. However, it has been shown that oligonucleotides are poorly cell permeable because of their complex chemical structure and due to their negatively charged backbone. Consequently, the general application of oligonucleotides in therapy is limited. Since miRNAs’ functions are executed exclusively by the Argonaute 2 protein, we therefore describe a protocol for the design of a novel miRNA inhibitor class: antagonists of the miRNA-Argonaute 2 protein complex, so-called anti-miR-AGOs, that not only block the crucial binding site of the target miRNA but also bind to the protein’s active site. Due to their lower molecular weight and, thus, more drug-like chemical structure, the novel inhibitor class may show better pharmacokinetic properties than reported oligonucleotide inhibitors, enabling them for potential therapeutic use.

Addressing miRNAs as drug targets may enable the cure, or at least the treatment of diseases, which presently seems impossible. However, due to miRNAs’ chemical structure, generation of potential drug molecules with necessary pharmacokinetic properties is still challenging and requires a re-thinking of the drug discovery process.

Recently, combined Answer Set Programming (ASP) and Quantifier Free Integer Difference Logic (QF-IDL) solving has been shown to be a promising approach in system synthesis. However, this approach still has several restrictions limiting its applicability. In the paper at hand, we propose a novel ASP modulo Theories (ASPmT) system synthesis approach, which (i) supports more sophisticated system models, (ii) tightly integrates the QF-IDL solving into the ASP solving, and (iii) makes use of partial assignment checking. As a result, more realistic systems are considered and an early exclusion of infeasible solutions improves the entire system synthesis.

This provides us with a general and flexible framework to study quantum field theories defined on spacetimes with extra geometric structures such as bundles, connections and spin structures. Using right Kan extensions, we can assign to any such theory an ordinary quantum field theory defined on the category of spacetimes and we shall clarify under which conditions it satisfies the axioms of locally covariant quantum field theory. The same constructions can be performed in a homotopy theoretic framework by using homotopy right Kan extensions, which allows us to obtain first toy-models of homotopical quantum field theories resembling some aspects of gauge theories.

Aberrant secretion by cancer cells can modulate this intercellular communication, in particular in highly organised tissues such as the liver. Hepatocytes, the major cell type of the liver, secrete Dickkopf (Dkk), which inhibits Wnt/ β-catenin signalling in an autocrine and paracrine manner. Consequently, Dkk modulates the expression of Wnt/ β-catenin target genes. We present a mathematical model that describes the autocrine and paracrine regulation of hepatic gene expression by Dkk under wild-type conditions as well as in the presence of mutant cells. Results Our spatial model describes the competition of Dkk and Wnt at receptor level, intra-cellular Wnt/ β-catenin signalling, and the regulation of target gene expression for 21 individual hepatocytes. Autocrine and paracrine regulation is mediated through a feedback mechanism via Dkk and Dkk diffusion along the porto-central axis. Along this axis an APC concentration gradient is modelled as experimentally detected in liver. Simulations of mutant cells demonstrate that already a single mutant cell increases overall Dkk concentration. The influence of the mutant cell on gene expression of surrounding wild-type hepatocytes is limited in magnitude and restricted to hepatocytes in close proximity. To explore the underlying molecular mechanisms, we perform a comprehensive analysis of the model parameters such as diffusion coefficient, mutation strength and feedback strength. Conclusions Our simulations show that Dkk concentration is elevated in the presence of a mutant cell. However, the impact of these elevated Dkk levels on wild-type hepatocytes is confined in space and magnitude. The combination of inter- and intracellular processes, such as Dkk feedback, diffusion and Wnt/ β-catenin signal transduction, allow wild-type hepatocytes to largely maintain their gene expression.

T1 - Towards identifying dyslexia in Standard Indonesian BT - the development of a reading assessment battery T2 - Postprints der Universität Potsdam Humanwissenschaftliche Reihe N2 - With its transparent orthography, Standard Indonesian is spoken by over 160 million inhabitants and is the primary language of instruction in education and the government in Indonesia. An assessment battery of reading and reading-related skills was developed as a starting point for the diagnosis of dyslexia in beginner learners. Founded on the International Dyslexia Association’s definition of dyslexia, the test battery comprises nine empirically motivated reading and reading-related tasks assessing word reading, pseudoword reading, arithmetic, rapid automatized naming, phoneme deletion, forward and backward digit span, verbal fluency, orthographic choice (spelling), and writing. The test was validated by computing the relationships between the outcomes on the reading-skills and reading-related measures by means of correlation and factor analyses. External variables, i.e., school grades and teacher ratings of the reading and learning abilities of individual students, were also utilized to provide evidence of its construct validity. Four variables were found to be significantly related with reading-skill measures: phonological awareness, rapid naming, spelling, and digit span. The current study on reading development in Standard Indonesian confirms findings from other languages with transparent orthographies and suggests a test battery including preliminary norm scores for screening and assessment of elementary school children learning to read Standard Indonesian.

As an ever-increasing number of policy issues are identified as an inherently ill-structured and intractable type of wicked problem, the question of what policy analysis sets out to accomplish has emerged as more central than ever. If solving wicked problems is beyond reach, research on wicked problems needs to provide a clearer understanding of the alternatives. The article identifies and explicates three distinguishable strategies of problem governance: coping, taming and solving. It shows that their intellectual premises and practical implications clearly contrast in core respects. The article argues that none of the identified strategies of problem governance is invariably more suitable for dealing with wicked problems. Rather than advocate for some universally applicable approach to the governance of wicked problems, the article asks under what conditions different ways of governing wicked problems are analytically reasonable and normatively justified. It concludes that a more systematic assessment of alternative approaches of problem governance requires a reorientation of the debate away from the conception of wicked problems as a singular type toward the more focused analysis of different dimensions of problem wickedness.

The complex consists of pelitic schists with minor psammitic and basic schists, calc silicate rocks, amphibolites, marbles, metavolcanosediments, mafic and felsic intrusives as well as ultramafic rocks. Metapelitic rocks show an amphibolite facies regional metamorphism and contain garnet, biotite, white mica, quartz, albite ± rutile ± apatite. Thermobarometry of garnet schist yields pressure of more than 9 kbar and temperatures between 560 and 675 °C. The geothermal gradient obtained for the peak of regional metamorphism is 19 °C/km, corresponding to a depth of ca. 31 km. Replacement of garnet by chlorite and epidote suggest greenschist facies metamorphism due to a decrease in temperature and pressure through exhumation and retrograde metamorphism (370–450 °C and 3–6 kbar). The metapelitic rocks followed a ‘clockwise’ P–T path during metamorphism, consistent with thermal decline following tectonic thickening. The formation of medium-pressure metamorphic rocks is related to presence of active subduction of the Neotethys Oceanic lithosphere beneath Eurasia in the Makran.

To examine whether a relationship between nutritional components and height can be found this pilot study has been developed. The research samples consisted of 44 children (age 3–6 years) attending two different kindergartens in Germany. Height measurements were taken for each child. Furthermore the parents had to fill out a 24-hour questionnaire to document their children’s eating habits during the weekend. In order to standardize the measured height values z-scores were calculated with reference to the average height of the overall cohort. The results of correlation analysis indicate that height is not significantly related to any of the main nutritional components as protein (r = –0.148), carbohydrates (r = 0.126), fat (r = 0.107), fibre (r = –0.289), vitamin (r = 0.050), calcium (r = 0.110), potassium (r = 0.189) and overall calorie intake (r = 0.302). In conclusion, it can be stated that the quality of nutrition may not have a strong influence on individual height. However, due to the small sample size further research should be provided with a larger cohort of children to verify the present results.

There were many foreigners among its students. This article focuses on the graduates born in the Ottoman Empire, particularly on Jews and Armenians. It analyses their backgrounds, their common features and their professional careers, tracing their links with other centraliens. The patterns in the Ottoman centraliens’ professional trajectories help us picture a world full of opportunities where highly qualified men could cross borders and build careers with ease, but where, at the same time, origins, allegiances, contacts and credentials mattered greatly.

Design/methodology/approach - The authors used two laboratory studies and paired 216 MBA students into single-gender teams of friends and non-friends, and then engaged them in several dyadic multi-issue negotiations. Findings - The results show that on average, male teams of non-friends reached significantly better outcomes than female teams of non-friends. However, and interestingly, female teams of friends perform equally to male teams of friends. Research limitations/implications - The authors contribute both to the negotiations and the workplace friendship literature because very little research has examined negotiation among friends at work and in particular team negotiations. In addition, the authors also contribute to the literature on gender differences in negotiations because existing research has rarely examined the differences between all-male and all-female teams and especially the relationship between same-sex teams and their effects on negotiation outcomes.

In current practice, either variable may serve as dependent variable or covariate for the other in linear mixed models (LMMs) featuring also psycholinguistic covariates of word recognition and sentence comprehension. Rather than analyzing fixation location and duration with separate LMMs, we propose linking the two according to their sequential dependency. Specifically, we include predicted fixation location (estimated in the first LMM from psycholinguistic covariates) and its associated residual fixation location as covariates in the second, fixation-duration LMM. This linked LMM affords a distinction between direct and indirect effects (mediated through fixation location) of psycholinguistic covariates on fixation durations. Results confirm the robustness of distributed processing in the perceptual span. They also offer a resolution of the paradox of the inverted optimal viewing position (IOVP) effect (i.e., longer fixation durations in the center than at the beginning and end of words) although the opposite (i.e., an OVP effect) is predicted from default assumptions of psycholinguistic processing efficiency: The IOVP effect in fixation durations is due to the residual fixation-location covariate, presumably driven primarily by saccadic error, and the OVP effect (at least the left part of it) is uncovered with the predicted fixation-location covariate, capturing the indirect effects of psycholinguistic covariates. We expect that linked LMMs will be useful for the analysis of other dynamically related multiple outcomes, a conundrum of most psychonomic research.

Where age differences emerge, these are usually ascribed to working-memory (WM) decline. Previous studies on the influence of WM on agreement computation have yielded inconclusive results, and work on aging and subject-verb agreement processing is lacking. In two experiments (Experiment 1: timed grammaticality judgment, Experiment 2: self-paced reading + WM test), we investigated older (OA) and younger (YA) adults’ susceptibility to agreement attraction errors. We found longer reading latencies and judgment reaction times (RTs) for OAs. Further, OAs, particularly those with low WM scores, were more accepting of sentences with attraction errors than YAs. OAs showed longer reading latencies for ungrammatical sentences, again modulated by WM, than YAs. Our results indicate that OAs have greater difficulty blocking intervening nouns from interfering with the computation of agreement dependencies. WM can modulate this effect.

Thispilot study aimed to investigate the pattern of longitudinal height z-scores changes in children before and after entering kindergarten. In summer 2016, we measured height and weight of 32 children from 4 groups of two kindergartens aged 3–6 years. All ages were centered according to the age of entry into the kindergarten. For each child we determined mean z-scores for height before and after entering the kindergarten, and assessed the variances for each kindergarten group. Twenty-two children targeted in height z-scores towards average height of their respective kindergarten group, 10 children did not. Due to the small numbers, the convergence in height variance however, remained insignificant (chi-squared independence test, p = 0.127). Additional studies with larger sample sizes are needed to confirm this pilot study.

T1 - The HESS II GRB Observation Scheme T2 - AIP conference proceedings / American Institute of Physics N2 - Gamma-ray bursts (GRBs) are some of the Universe’s most enigmatic and exotic events. However, at energies above 10 GeV their behaviour remains largely unknown. Although space based telescopes such as the Fermi-LAT have been able to detect GRBs in this energy range, their photon statistics are limited by the small detector size. Such limitations are not present in ground based gamma-ray telescopes such as the H.E.S.S. experiment, which has now entered its second phase with the addition of a large 600 m2 telescope to the centre of the array. Such a large telescope allows H.E.S.S. to access the sub 100-GeV energy range while still maintaining a large effective collection area, helping to potentially probe the short timescale emission of these events. We present a description of the H.E.S.S. GRB observation programme, summarising the performance of the rapid GRB repointing system and the conditions under which GRB observations are initiated. Additionally we will report on the GRB follow-ups made during the 2014-15 observation campaigns.

While the source does not have a clear counterpart at longer wavelengths, the very hard spectrum emission at TeV energies implies that electrons or protons accelerated up to several hundreds of TeV are responsible for the emission. In the hadronic case, the VHE emission can be produced by runaway cosmic-rays colliding with the dense molecular clouds spatially coincident with the H.E.S.S. source.

Typical applications are found in precision agriculture, archaeological prospecting and soil sciences. With the typical survey setting, the collected data sets are often characterized by a rather high level of noise and a rather coarse lateral sampling compared to data acquired with fixed electrodes. We therefore present an efficient one-dimensional inversion approach in which we put special attention on modeling the effects of noise. We apply this method to data recorded with a five-offset equatorial dipole-dipole system employing rolling electrodes. By performing several synthetic tests with realistic noise levels, we found that the considered five-configuration soundings allow for a reliable imaging of two-layer cases in the uppermost two meters of the subsurface, where the subsurface can be assumed to follow a horizontally layered geometry within 3 m around the system. By analyzing the corresponding sensitivity functions, we also show that the equatorial dipole-dipole array is relatively well suited for a 1D inversion approach compared to standard in-line electrode arrays. To illustrate this aspect, we show that our method can provide results similar to those obtained with a 2D Wenner imaging procedure for data recorded across a well-constrained 2D target. We finally apply our method to a large five-offset data set acquired in an agricultural study. The final pseudo-3D model of electrical resistivity is in accordance with borehole data available for the surveyed area. Our results demonstrate the applicability and the versatility of the presented inversion approach for large-scale data sets as they are typically collected with such rolling electrode systems.

Methods: Ten healthy individuals (20 feet) were enrolled. Participants were assessed twice by two raters each to determine intrarater and interrater reliability. For each foot, three transverse scans of the central bundle of the PF were taken at its insertion at the medial calcaneal tubercle, identified in real time on the plantar surface of the foot, using a fine wire technique. Reliability was determined using intraclass correlation coefficients (ICC), standard errors of measurement (SEM), and limits of agreement (LOA) expressed as percentages of the mean. Reliability of PF width and CSA measurements was determined using PF width and CSA measurements from one sonogram measured once and the mean of three measurements from three sonograms each measured once. Results: Ultrasound measurements of PF width and CSA showed a mean of 18.6 +/- 2.0 mm and 69.20 +/- 13.6 mm(2) respectively. Intra-reliability within both raters showed an ICC. 0.84 for width and ICC. 0.92 for CSA as well as a SEM% and LOA%, 10% for both width and CSA. Inter-rater reliability showed an ICC of 0.82 for width and 0.87 for CSA as well as a SEM% and LOA%, 10% for width and a SEM%, 10% and LOA%, 20% for CSA. Relative and absolute reliability within and between raters were higher when using the mean of three sonographs compared to one sonograph. Conclusions: Using this novel technique, PF CSA and width may be determined reliably using measurements from one sonogram or the mean of three sonograms. Measurement of PF CSA and width in addition to already established thickness and echogenicity measurements provides additional information on structural properties of the PF for clinicians and researchers in healthy and pathologic PF.

Characters outside a window of legible text were replaced by visually similar characters. Results show that the influence of window size on the perceptual span was consistent across different fixation and oculomotor measures. To maintain normal reading behavior when reading aloud, it was necessary to have information provided from three characters to the right of the fixation. Together with findings from previous research, our findings suggest that the physical size of the perceptual span is smaller when reading aloud than in silent reading. This is in agreement with previous studies in English, suggesting that the mechanisms causing the reduced span in oral reading have a common base that generalizes across languages and writing systems.

Can these observations - primarily from North America, China and Australia - usefully be applied to seismic hazard assessment for intraplate Europe? Existing assessments are based on instrumental and historical seismicity of the past c. 1000 years, as well as some data for active faults. This time span probably fails to capture typical large-event recurrence intervals of the order of tens of thousands of years. Palaeoseismology helps to lengthen the observation window, but preferentially produces data in regions suspected to be seismically active. Thus the expected maximum magnitudes of future earthquakes are fairly uncertain, possibly underestimated, and earthquakes are likely to occur in unexpected locations. These issues particularly arise in considering the hazards posed by low-probability events to both heavily populated areas and critical facilities. For example, are the variations in seismicity (and thus assumed seismic hazard) along the Rhine Graben a result of short sampling or are they real? In addition to a better assessment of hazards with new data and models, it is important to recognize and communicate uncertainties in hazard estimates. The more users know about how much confidence to place in hazard maps, the more effectively the maps can be used.

In this study I examined the effect of migration of tall individuals into network hubs on the dynamics of body height within the whole spatial network. The aim of this study was to simulate height trends. Material and methods: Three networks were used for modeling, a regular rectangular fishing net like network, a real world example based on the geographic map of Switzerland, and a random network. All networks contained between 144 and 148 districts and between 265-307 road connections. Around 100,000 agents were initially released with average height of 170 cm, and height standard deviation of 6.5 cm. The simulation was started with the a priori assumption that height variation within a district is limited and also depends on height of neighboring districts (community effect on height). In addition to a neighborhood influence factor, which simulates a community effect, body height dependent migration of conscripts between adjacent districts in each Monte Carlo simulation was used to re-calculate next generation body heights. In order to determine the direction of migration for taller individuals, various centrality measures for the evaluation of district importance within the spatial network were applied. Taller individuals were favored to migrate more into network hubs, backward migration using the same number of individuals was random, not biased towards body height. Network hubs were defined by the importance of a district within the spatial network. The importance of a district was evaluated by various centrality measures. In the null model there were no road connections, height information could not be delivered between the districts. Results: Due to the favored migration of tall individuals into network hubs, average body height of the hubs, and later, of the whole network increased by up to 0.1 cm per iteration depending on the network model. The general increase in height within the network depended on connectedness and on the amount of height information that was exchanged between neighboring districts. If higher amounts of neighborhood height information were exchanged, the general increase in height within the network was large (strong secular trend). The trend in the homogeneous fishnet like network was lowest, the trend in the random network was highest. Yet, some network properties, such as the heteroscedasticity and autocorrelations of the migration simulation models differed greatly from the natural features observed in Swiss military conscript networks. Autocorrelations of district heights for instance, were much higher in the migration models. Conclusion: This study confirmed that secular height trends can be modeled by preferred migration of tall individuals into network hubs. However, basic network properties of the migration simulation models differed greatly from the natural features observed in Swiss military conscripts. Similar network-based data from other countries should be explored to better investigate height trends with Monte Carlo migration approach.

Material and methods: After digitalizing available body height data of Norwegian draftees in 1877-1878, 1880 (averaged as 1878), and 1895-1897 (averaged as 1896) we calculated the magnitude of autocorrelation of body height within the same municipality at different time points. Furthermore, we generated three different neighborhood networks, (1) based on Euclidean distances, (2) a minimum spanning tree build on those distances, (3) a network founded on real world road connections. The networks were used to determine the correlation between body height of neighboring districts depending on the number of edges required to connect two municipalities. Results: The autocorrelation value for body heights was around r = 0.5 (for all p < 0.001) in the years 1878 and 1896. The correlation between neighboring districts varied in the Euclidean distance based network between 0.47 and 0.27 approximately for both years in a sorted order, descending from nearest (0-50 km) to farthest (150-200 km, for all p < 0.001). First order neighbors in the minimum spanning tree network correlation was 0.36 in 1878 and 0.42 in 1896 (for all p < 0.001). The values of neighbor correlation in the road connection based network ranged in 1878 from 0.42 (first order neighbors) to 0.17 (forth order neighbors, for all p < 0.01) and in 1896 from 0.46 (first order neighbors) to 0.12 (forth order neighbors, for all p < 0.05). Conclusion: This initial study of Norwegian conscript height data from the 19th century showed significant medium sized effects for the within district autocorrelation between 1878 and 1896 as well as medium neighborhood correlation, slightly lower in comparison to a recent study regarding Swiss conscripts. Digitalizing more data from other years in this and later time spans as well as using older road and ship connections instead of the actual road data might stabilize and improve those findings.

Building on prior mapping of the event, we traced its rupture in the field and measured more than 50 offset landforms. Cumulative fault rupture length is >155-195 km along 13 fault patches comprising six sections. The patches are separated by changes of dip magnitude or dip direction, or by 4-10 km-wide stepovers. One <40 km section overlaps and is parallel to the main north-dipping rupture but is 7 km north and dips opposite (south). Both ends of the rupture are along mountain front thrust faults demonstrating late Quaternary activity. We computed the moment from each fault patch using the surface fault traces, dip inferred from the traces, 20 km seismogenic thickness, rigidity of 3.3 x 10(10) N m(-2) and dip slip converted from our observations of the largely reverse sense of motion vertical offsets. The discontinuous patches with c. 3-4 m average slip and peak slip of <14 m yield a seismic moment of 4.6 x 10(20) Nm (M-w 7.78) to 7.4 x 10(20) Nm (M-w 7.91). The majority of moment was released along the inner eastern rupture segments. This geological moment is lower by a factor of 1.5 from that determined from teleseismic data.

Moreover, some of our instincts developed for assessing hazards at plate boundaries might not apply here. Hence assessing hazards and drawing implications for the future is challenging, and how well it can be done heavily depends on the ability to assess the spatiotemporal distribution of past large earthquakes. This book explores some key issues in understanding hazards in slowly deforming areas. Examples include classic intraplate regions, such as Central and Northern Europe, Mongolia, Inner Mongolia, Australia, and North and South America, and regions of widely distributed strain, such as the Tien Shan Mountains in Central Asia. The papers in this volume are grouped into two sections. The first section deals with instrumental and historical earthquake data and associated hazard assessments.

In these cases, two positions are occupied in the forefield in front of the finite verb, usually by an adverbial and a subject, which identify, at the level of information structure, frame-setter and topic, respectively. Our study investigates the influence of verbal versus language -independent information-structural preferences for this linearisation, comparing Turkish-German multilingual speakers who have grown up in Germany with monolingual German and Turkish speakers. For tasks, in which grammatical restrictions were largely minimised, the results indicate a general tendency to place verbs in a position after the frame-setter and the topic; in addition, we found language-specific influences that distinguish Turkish-German and monolingual German speakers from monolingual Turkish ones. We interpret this as evidence for an information-structural motivation for verb-third, and for a clear dominance of German for Turkish-German speakers in Germany.

Als Haupttransmissionsweg gilt die frühe Mutter-Kind-Interaktion. Über die langfristigen Auswirkungen auf die Kinder im Erwachsenenalter und die Rolle der Interaktion liegen kaum Ergebnisse vor. Im Rahmen der Mannheimer Risikokinderstudie wurden postpartale Depressionen bis zwei Jahre nach der Geburt erfasst. Die kindliche Entwicklung wurde fortlaufend und die Mutter-Kind-Interaktion im Alter von 3 Monaten standardisiert erhoben. 28 Kinder postpartal depressiver und 107 Kinder gesunder Mütter konnten mit 25 Jahren untersucht werden. Beeinträchtigungen der kognitiven und psychischen Entwicklung bei Kindern postpartal depressiver Mütter waren bis ins Erwachsenenalter nachweisbar. Responsives bzw. sensitives mütterliches Verhalten wirkte der negativen Entwicklung entgegen. Dies betont die Bedeutung einer hohen Qualität der Mutter-Kind-Interaktion für die Entwicklung von Risikokindern. N2 - Postpartum depression (PPD) is a common and serious mental health problem with prevalence rates ranging from 13 % to 19 %, and is associated with an increased risk of adverse child development. PPD is characterized by symptoms common of depression, particularly by impairments of maternity, parenting, and mother–infant interactions. Several reviews suggest an impact on attachment, cognitive, behavioral, and health-related outcome in the offspring. However, the long-term effects of PPD regarding cognitive and mental development into adulthood and the underlying mechanisms, especially the role of maternal interactional behavior, are not yet well understood. In the Mannheim Study of Children at Risk, maternal depression was assessed when the child was 3 months and 2 years old. Development from infancy to young adulthood (25 years) was assessed at regular intervals in 28 children of postnatally depressed mothers and 107 children born to mentally healthy mothers. Cognitive outcome up to age 11 was measured using standardized instruments; in adulthood, school outcome was used approximately. Psychiatric diagnosis as well as symptom scores served as psychological outcome. At age 3 months, mothers and infants were videotaped during a nursing and a playing situation. Videotapes of the 10-min session were recorded and evaluated by trained raters (κ > .83) using the Category System for Microanalysis of Early Mother Child Interaction (Esser, Scheven, et al., 1989). The cognitive as well as social–emotional outcome of children of mothers suffering from PPD was significantly poorer than in the children of mentally healthy mothers. The adverse effects were more pronounced during childhood. The offspring of postnatally depressed mothers who interacted in a responsive manner with their infant exhibited a better prognosis in contrast to those with mothers interacting less sensitively. This effect was observed with regard to cognitive development and symptoms of externalizing behavior at age 19 years. Regarding internalizing behavior, no impact of maternal behavior was detected. These findings emphasize the importance of high-quality early mother–child interaction in the development of children at risk. Furthermore, convincing arguments are given for very early specialized treatment of impaired mother–child interactions in mothers suffering from PPD. The PPD treatment should always comprise treatment of depression as well as treatment of the disturbed mother–child interaction.

Im Alter von 8 – 15 Jahren wurde dreimal das Child Behavior Checklist-Dysregulationsprofil (CBCL-DP) erhoben. Mit 25 Jahren wurde ein Strukturiertes Klinisches Interview durchgeführt und 309 der Teilnehmer füllten den Young Adult Self-Report aus. Frühe psychosoziale Risiken gingen mit einem erhöhten Risiko für das Vorliegen eines Substanzmissbrauchs im jungen Erwachsenenalter sowie mit erhöhtem externalisierendem und internalisierendem Problemverhalten einher. Der Zusammenhang zwischen frühen psychosozialen Risiken und späterem externalisierendem bzw. internalisierendem Problemverhalten wurde durch das CBCL-DP vermittelt. N2 - Numerous studies suggested an association between childhood adversities and later increased risk for mental illness. However, most studies have used adults’ retrospective self-reports for assessing adverse childhood experiences. Mechanisms underlying the association between childhood adversities and later psychopathology are not yet well understood. In the Mannheim Study of Children at Risk, we prospectively examined the impact of early psychosocial risks on psychopathology in early adulthood. In addition, we tested the mediating role of childhood affective and behavioral dysregulation. In a total of 384 infants from the Rhine-Neckar region of Germany born between 1986 and 1988, the presence of 11 adverse family factors was assessed by use of a standardized parent interview conducted when the child was 3 months old. At the child’s age of 8, 11, and 15 years, parents completed the Child Behavior Checklist (CBCL). The CBCL-Dysregulation Profile (CBCL-DP) was formed by summing up the scores of the syndrome scales of aggressive, inattentive, and anxious/depressed behavior. At the age of 25 years, the Structured Clinical Interview for DSM-IV (SCID) was conducted with n = 307 participants to obtain psychiatric diagnoses for the period of young adulthood. In addition, 309 participants filled out the Young Adult Self-Report (YASR) to assess current externalizing and internalizing problem behavior. With respect to psychiatric diagnoses during young adulthood, early psychosocial risks were associated with a significantly increased probability for suffering from substance abuse/dependence. By contrast, risk was not significantly increased for anxiety, depressive, and personality disorders. In addition, early psychosocial risks significantly predicted externalizing and internalizing behavior problems as measured by the YASR. The CBCL-DP was found to mediate this association. To conclude, our results confirm an association between childhood adversities and psychopathology in adulthood. Hence, findings from retrospective studies can also be replicated by the use of prospective study designs. Affective and behavioral dysregulation as measured by the CBCL-DP seems to be a mediating bridge between early psychosocial risks and long-term adverse consequences. The CBCL-DP may be used to identify children at an enhanced risk for developing chronic mental problems.

Eine besondere Rolle kommt dabei positiven frühen Eltern-Kind-Beziehungen zu (sowohl Mutter- als auch Vater-Kind-Interaktionen). Daneben spielen auch Interaktionserfahrungen im Alter von zwei Jahren des Kindes eine bedeutsame Rolle; diese schützen Risikokinder davor, eine ungünstige Entwicklung zu nehmen und tragen dazu bei, dass sich Kinder, die in psychosozialen Hochrisikofamilien aufwachsen, trotz ungünstiger „Startbedingungen“ positiv entwickeln. Neben Merkmalen der sozialen Umwelt nehmen auch sprachliche, sozial-emotionale und internale Kompetenzen des Kindes im Entwicklungsverlauf eine wichtige Rolle ein. Diese Kompetenzen ermöglichen es Risikokindern auch unter widrigen Lebensumständen (psychosoziale Hochrisikofamilien, Aufwachsen in Armutsverhältnissen) erfolgreich zu bestehen. Darüber hinaus zeigt die Arbeit, dass Resilienz ein Persönlichkeitsmerkmal ist, das ab dem frühen Erwachsenenalter eine hohe Stabilität besitzt. Mit diesen Befunden verweist die Arbeit auf die große Bedeutung der Resilienz bei der Vorhersage der langfristigen Entwicklung von Risikokindern. N2 - Resilience refers to the ability to successfully deal with stressful life circumstances and experiences and to cope with them. Based on data from the Mannheim Study of Children at Risk, which follows a sample of children at risk from birth to adulthood, the present paper provides convincing evidence demonstrating how protective factors in the child and his/her family environment operate during the course of development to contribute to the development of resilience. As shown, a major role is assigned to positive early parent–child relationships (both mother– and father–child interactions). Moreover, positive interactive experiences at the child’s age of 2 years play a significant role. These experiences consistently contribute to a positive child development in the face of adversity. In addition to characteristics of the social environment of the child, cognitive, social–emotional, and internal competencies during childhood, youth, and young adulthood play a major role in the development of resilience. These competencies enable children at risk who are growing up in psychosocial high-risk families or in poverty to successfully cope with conditions of high adversity. Moreover, the findings presented here demonstrate that resilience may be conceived as a personal characteristic that exhibits high stability since young adulthood. With these findings, the present study points to the significance of resilience in predicting the long-term outcome of children at risk.

Frühgeborene wiesen mit 11 Jahren einen signifikant niedrigeren IQ als Reifgeborene auf, nachdem für mögliche konfundierende Faktoren kontrolliert worden war. Nur bei Früh-, nicht aber bei Reifgeborenen zeigte sich ein signifikanter positiver Zusammenhang zwischen mütterlicher Responsivität und IQ. Für die Wahrscheinlichkeit einen höheren Schulabschluss (mind. Fachabitur) zu erreichen, fand sich weder ein signifikanter Effekt von Frühgeburtlichkeit noch von mütterlicher Responsivität. N2 - Preterm birth is associated with adverse long-term consequences regarding cognitive development. Whereas children born very preterm represent a subgroup at special risk, also so-called “late preterms” are affected to a lesser degree. Effects of prematurity can be observed until adulthood. For example, decreased wealth was reported in adults born preterm, which was mediated by decreased intelligence during childhood and lower educational qualifications during young adulthood. Hence, it is highly relevant to examine whether certain factors can buffer against the adverse effects of preterm birth on cognitive development. Parenting might play an important role here. There is evidence suggesting a protective effect of sensitive parenting during childhood on later cognitive outcome in preterms. In the current study, we examined whether early responsive maternal care was associated with later intelligence and academic achievement in children born preterm versus fullterm. As part of an ongoing cohort study, early maternal responsiveness was assessed at the child's age of 3 months (adjusted for gestational age) during a nursing and playing situation. At age 11 years, general intelligence (IQ) was determined in n=351 children (101 born preterm; 168 male). Until age 25 years, educational qualification was assessed in n=313 participants (85 born preterm; 145 male). IQ at age 11 was significantly lower in preterms compared to fullterms after adjusting for potential confounders like maternal educational background and early psychosocial risk. A significant interaction between preterm birth and early maternal responsiveness was detected. In preterms only, higher levels of early maternal responsiveness were significantly associated with higher child IQ. Lower IQs in children born preterm as compared to fullterm were observed in the subaverage to average range of maternal responsiveness. Interestingly, preterms exposed to very high levels of maternal responsiveness showed slightly higher IQs when compared to children born at term. With regard to academic achievement, neither a significant effect of preterm birth nor of early maternal responsiveness occurred after adjusting for potential confounders. The results of the current study replicate and extend earlier findings with regard to a protective effect of sensitive parenting on childhood cognitive outcome in preterms. The lacking impact of prematurity on academic achievement may be explained by the exclusion of participants with IQs outside the normal range in the current study.

However, the interrelatedness of these two number couplings is still unclear. The present study examines the simultaneous occurrence of space- and size-numerical congruency effects and their interactions both within and across trials, in a magnitude judgment task physically small or large digits were presented left or right from screen center. The reaction times analysis revealed that space- and size-congruency effects coexisted in parallel and combined additively. Moreover, a selective sequential modulation of the two congruency effects was found. The size-congruency effect was reduced after size incongruent trials. The space-congruency effect, however, was only affected by the previous space congruency. The observed independence of spatial-numerical and within magnitude associations is interpreted as evidence that the two couplings reflect Different attributes of numerical meaning possibly related to orginality and cardinality.

A combination of observation data and regional climate simulations of past and future climates (1970-2013, 2046-2065, and 2081-2100) were analyzed for the study. The Standardized Precipitation Index (SPI) and Standardized Precipitation and Evapotranspiration (SPEI) were used to characterize drought while the Standardized Runoff Index (SRI) were used to quantify runoff. Results of the study show that the historical pattern of drought is generally consistent with previous studies over the Basin and most part of West Africa. RCA ensemble medians (RMED) give realistic simulations of drought characteristics and area extent over the Basin and the sub-catchments in the past climate. Generally, an increase in drought intensity and spatial extent are projected over VRB for SPEI and SPI, but the magnitude of increase is higher with SPEI than with SPI. Drought frequency (events per decade) may be magnified by a factor of 1.2, (2046-2065) to 1.6 (2081-2100) compared to the present day episodes in the basin. The coupling between streamflow and drought episodes was very strong (P < 0.05) for the 1-16-year band before the 1970 but showed strong correlation all through the time series period for the 4-8 -years band. Runoff was highly sensitive to precipitation in the VRB and a 2-3 month time lag was found between drought indices and streamflow in the Volta River Basin. Results of this study may guide policymakers in planning how to minimize the negative impacts of future climate change that could have consequences on agriculture, water resources and energy supply.

Unraveling the underlying molecular mechanisms of spatiotemporal pattern formation remains one of the outstanding challenges at the interface between physics and biology. A fundamental recurrent pattern found in many different cell types is that of self-sustained oscillations. They are involved in a wide range of cellular functions, including second messenger signaling, gene expression, and cytoskeletal dynamics. Here, we review recent developments in the field of cellular oscillations and focus on cases where concepts from physics have been instrumental for understanding the underlying mechanisms. We consider biochemical and genetic oscillators as well as oscillations that arise from chemo-mechanical coupling. Finally, we highlight recent studies of intracellular waves that have increasingly moved into the focus of this research field.

Firstly, the study of pointwise power decay rates almost everywhere of the quadratic tilt-excess is completed by establishing the precise decay rate for two-dimensional integral varifolds of locally bounded first variation. In order to obtain the exact decay rate, a coercive estimate involving a height-excess quantity measured in Orlicz spaces is established. Moreover, counter-examples to pointwise power decay rates almost everywhere of the super-quadratic tilt-excess are obtained. These examples are optimal in terms of the dimension of the varifold and the exponent of the integrability condition in most cases, for example if the varifold is not two-dimensional. These examples also demonstrate that within the scale of Lebesgue spaces no local higher integrability of the second fundamental form, of an at least two-dimensional curvature varifold, may be deduced from boundedness of its generalised mean curvature vector. Amongst the tools are Cartesian products of curvature varifolds.

In order to counteract the geographical mismatch of workers, the German active labor market policy offers a subsidy covering moving costs to incentivize unemployed job seekers to search/accept jobs in distant regions. Based on administrative data, this study provides the first empirical evidence on the impact of this subsidy on participants' prospective labor market outcomes. We use an instrumental variable approach to take endogenous selection based on observed and unobserved characteristics into account when estimating causal treatment effects. We find that unemployed job seekers who participate in the subsidy program and move to a distant region receive higher wages and find more stable jobs compared to non-participants. We show that the positive effects are (to a large extent) the consequence of a better job match due to the increased search radius of participants.

This process, however, is impeded by the high strength of passive margins, and it has never occurred in Cenozoic times. Here using thermomechanical models, we show that additional forcing, provided by mantle flow, which is induced by neighboring subduction zones and midmantle slab remnants, can convert a passive margin into a subduction zone. Models suggest that this is a long-term process, thus explaining the lack of Cenozoic examples. We speculate that new subduction zones may form in the next few tens of millions of years along the Argentine passive margin and the U.S. East Coast. Mantle suction force can similarly trigger subduction initiation along large oceanic fracture zones. We propose that new subduction zones will preferentially originate where subduction zones were active in the past, thus explaining the remarkable colocation of subduction zones during at least the last 400 Myr.

T1 - Computerised mirror therapy with Augmented Reflection Technology for early stroke rehabilitation BT - clinical feasibility and integration as an adjunct therapy JF - Disability and rehabilitation : an international, multidisciplinary journal N2 - Purpose: New rehabilitation strategies for post-stroke upper limb rehabilitation employing visual stimulation show promising results, however, cost-efficient and clinically feasible ways to provide these interventions are still lacking. An integral step is to translate recent technological advances, such as in virtual and augmented reality, into therapeutic practice to improve outcomes for patients. This requires research on the adaptation of the technology for clinical use as well as on the appropriate guidelines and protocols for sustainable integration into therapeutic routines. Here, we present and evaluate a novel and affordable augmented reality system (Augmented Reflection Technology, ART) in combination with a validated mirror therapy protocol for upper limb rehabilitation after stroke. Results: The results showed that the combination and application of the Berlin Protocol for Mirror Therapy together with ART was feasible for clinical use. This combination was integrated into the therapeutic plan of subacute stroke patients at the two clinical locations where the second part of this research was conducted. Conclusions: Our findings pave the way for using technology to provide mirror therapy in clinical settings and show potential for the more effective use of inpatient time and enhanced recoveries for patients.

Today Gabelentz is chiefly remembered for several insights that proved to be productive in the development of subsequent schools and subdisciplines. In this paper, we examine two of these insights, his analytic and synthetic systems of grammar and his foundational work on typology. We show how they were intimately connected within his conception of linguistic research, and how this was in turn embedded in the tradition established by Wilhelm von Humboldt (1767–1835), especially as it was further developed by H. Steinthal (1823–1899). This paper goes beyond several previous works with a similar focus by drawing on a wider range of Gabelentz’ writings, including manuscript sources that have only recently been published, and by examining specific textual connections between Gabelentz and his predecessors.

Not only the moral status of lying has been intensively discussed but also what it means to lie in the first place. Perhaps the most important criterion for an adequate definition of lying is that it fits with people’s understanding and use of this concept. In this light, it comes as a surprise that researchers only recently started to empirically investigate the folk concept of lying. In this paper, we describe three experimental studies which address the following questions: Does a statement need to be objectively false in order to constitute lying? Does lying necessarily include the intention to deceive? Can one lie by omitting relevant facts?

While this competition is challenging for many merchants, it also provides plenty of opportunities, e.g., by allowing them to automatically adjust prices in order to react to changing market situations. For practitioners however, testing automated pricing strategies is time-consuming and potentially hazardously when done in production. Researchers, on the other side, struggle to study how pricing strategies interact under heavy competition. As a consequence, we built an open continuous time framework to simulate dynamic pricing competition called Price Wars. The microservice-based architecture provides a scalable platform for large competitions with dozens of merchants and a large random stream of consumers. Our platform stores each event in a distributed log. This allows to provide different performance measures enabling users to compare profit and revenue of various repricing strategies in real-time. For researchers, price trajectories are shown which ease evaluating mutual price reactions of competing strategies. Furthermore, merchants can access historical marketplace data and apply machine learning. By providing a set of customizable, artificial merchants, users can easily simulate both simple rule-based strategies as well as sophisticated data-driven strategies using demand learning to optimize their pricing strategies.
