While reference grammars treat complementizers with a determiner as the standard option, previous diachronic research has shown that determiner-less complementizers actually predate relative complementizers with a determiner. Additionally, Yucatecan Spanish has been in long-standing contact with Yucatec Maya. Relative complementation in Yucatec Maya differs from that in Spanish (at least) in that the non-complex complementizer tu'ux ('where') is generally the only option for locative complementation. The paper explores monolingual and bilingual data from Yucatecan Spanish to discuss the question whether the determiner-less and bare que relative complementizers in our data constitute a historic remnant or a dialectal recast, possibly (but not necessarily) due to language contact. Although our pilot study may not answer these far-reaching questions, it does reveal two separate, but intertwined developments: (i) a generally increased rate of bare que relative complementation, across both monolingual speakers of Spanish and Spanish Maya bilinguals, compared to other Spanish varieties, and (ii) a preference for donde at the cost of other locative complementizer constructions in the bilingual group. Our analysis thus reveals intriguing differences between the complementizer preferences of monolingual and bilingual speakers, suggesting that different variational patterns caused by different (socio-)linguistic factors can co-develop in parallel in one and the [same] region.}, language = {en} } @article{BuerkiFoschiniMadec2022, author = {B{\"u}rki-Foschini, Audrey Damaris and Madec, Sylvain}, title = {Picture-Word interference in language production studies}, series = {Journal of experimental psychology : Learning, memory, and cognition}, volume = {48}, journal = {Journal of experimental psychology : Learning, memory, and cognition}, number = {7}, publisher = {American Psychological Association}, address = {Washington}, issn = {0278-7393}, doi = {10.1037/xlm0001098}, pages = {1019 -- 1046}, year = {2022}, abstract = {The picture-word interference paradigm (participants name target pictures while ignoring distractor words) is often used to model the planning processes involved in word production. The participants' naming times are delayed in the presence of a distractor (general interference). The size of this effect depends on the relationship between the target and distractor words. Distractors of the same semantic category create more interference (semantic interference), and distractors overlapping in phonology create less interference (phonological facilitation). The present study examined the relationships between these experimental effects, processing times, and attention in order to better understand the cognitive processes underlying participants' behavior in this paradigm. Participants named pictures with a superimposed line of Xs, semantically related distractors, phonologically related distractors, or unrelated distractors. General interference, semantic interference, and phonological facilitation effects were replicated. Distributional analyses revealed that general and semantic interference effects increase with naming times, while phonological facilitation decreases. The phonological facilitation and semantic interference effects were found to depend on the synchronicity in processing times between the planning of the picture's name and the processing of the distractor word. Finally, electroencephalographic power in the alpha band before stimulus onset varied with the position of the trial in the experiment and with repetition but did not predict the size of interference/facilitation effects. Taken together, these results suggest that experimental effects in the picture-word interference paradigm depend on processing times to both the target word and distractor word and that distributional patterns could partly reflect this dependency.}, language = {en} } @article{EiteljoergeAdamElsneretal.2019, author = {Eiteljoerge, Sarah Fe Vivian and Adam, Maurits and Elsner, Birgit and Mani, Nivedita}, title = {Consistency of co-occurring actions influences young children's word learning learning}, series = {Royal Society Open Science}, volume = {6}, journal = {Royal Society Open Science}, number = {8}, publisher = {Royal Society}, address = {London}, issn = {2054-5703}, doi = {10.1098/rsos.190097}, pages = {17}, year = {2019}, abstract = {Communication with young children is often multimodal in nature, involving, for example, language and actions. The simultaneous presentation of information from both domains may boost language learning by highlighting the connection between an object and a word, owing to temporal overlap in the presentation of multimodal input. However, the overlap is not merely temporal but can also covary in the extent to which particular actions co-occur with particular words and objects, e.g. carers typically produce a hopping action when talking about rabbits and a snapping action for crocodiles. The frequency with which actions and words co-occurs in the presence of the referents of these words may also impact young children's word learning. We, therefore, examined the extent to which consistency in the co-occurrence of particular actions and words impacted children's learning of novel word-object associations. Children (18 months, 30 months and 36-48 months) and adults were presented with two novel objects and heard their novel labels while different actions were performed on these objects, such that the particular actions and word-object pairings always co-occurred (Consistent group) or varied across trials (Inconsistent group). At test, participants saw both objects and heard one of the labels to examine whether participants recognized the target object upon hearing its label. Growth curve models revealed that 18-month-olds did not learn words for objects in either condition, and 30-month-old and 36- to 48-month-old children learned words for objects only in the Consistent condition, in contrast to adults who learned words for objects independent of the actions presented. Thus, consistency in the multimodal input influenced word learning in early childhood but not in adulthood. In terms of a dynamic systems account of word learning, our study shows how multimodal learning settings interact with the child's perceptual abilities to shape the learning experience.}, language = {en} } @article{HuttenlauchBeerHanneKlothetal.2021, author = {Huttenlauch, Clara and Beer, Carola de and Hanne-Kloth, Sandra and Wartenburger, Isabell}, title = {Production of prosodic cues in coordinate name sequences addressing varying interlocutors}, series = {Laboratory phonology}, volume = {12}, journal = {Laboratory phonology}, number = {1}, publisher = {Ubiquity Press}, address = {London}, issn = {1868-6346}, doi = {10.5334/labphon.221}, pages = {31}, year = {2021}, abstract = {Prosodic boundaries can be used to disambiguate the syntactic structure of coordinated name sequences (coordinates). To answer the question whether disambiguating prosody is produced in a situationally dependent or independent manner and to contribute to our understanding of the nature of the prosody-syntax link, we systematically explored variability in the prosody of boundary productions of coordinates evoked by different contextual settings in a referential communication task. Our analysis focused on prosodic boundaries produced to distinguish sequences with different syntactic structures (i.e., with or without internal grouping of the constituents). In German, these prosodic boundaries are indicated by three major prosodic cues: f0-range, final lengthening, and pause. In line with the Proximity/Anti-Proximity principle of the syntax-prosody model by Kentner and Fery (2013), speakers clearly use all three cues for constituent grouping and prosodically mark groups within and at their right boundary, indicating that prosodic phrasing is not a local phenomenon. Intra-individually, we found a rather stable prosodic pattern across contexts. However, inter-individually speakers differed from each other with respect to the prosodic cue combinations that they (consistently) used to mark the boundaries. Overall, our data speak in favour of a close link between syntax and prosody and for situational independence of disambiguating prosody.}, language = {en} } @article{KormannFranckeRenneretal.2015, author = {Kormann, C. and Francke, Till and Renner, M. and Bronstert, Axel}, title = {Attribution of high resolution streamflow trends in Western Austria}, series = {Hydrology and earth system sciences}, volume = {19}, journal = {Hydrology and earth system sciences}, publisher = {EGU}, address = {Katlenburg-Lindau}, issn = {1607-7938}, doi = {10.5194/hess-19-1225-2015}, pages = {1225 -- 1245}, year = {2015}, abstract = {The results of streamflow trend studies are often characterized by mostly insignificant trends and inexplicable spatial patterns. In our study region, Western Austria, this applies especially for trends of annually averaged runoff. However, analysing the altitudinal aspect, we found that there is a trend gradient from higher-altitude to lower-altitude stations, i.e. a pattern of mostly positive annual trends at higher stations and negative ones at lower stations. At midaltitudes, the trends are mostly insignificant. Here we hypothesize that the streamflow trends are caused by the following two main processes: on the one hand, melting glaciers produce excess runoff at higher-altitude watersheds. On the other hand, rising temperatures potentially alter hydrological conditions in terms of less snowfall, higher infiltration, enhanced evapotranspiration, etc., which in turn results in decreasing streamflow trends at lower-altitude watersheds. However, these patterns are masked at mid-altitudes because the resulting positive and negative trends balance each other. To support these hypotheses, we attempted to attribute the detected trends to specific causes. For this purpose, we analysed trends of filtered daily streamflow data, as the causes for these changes might be restricted to a smaller temporal scale than the annual one. This allowed for the explicit determination of the exact days of year (DOYs) when certain streamflow trends emerge, which were then linked with the corresponding DOYs of the trends and characteristic dates of other observed variables, e.g. the average DOY when temperature crosses the freezing point in spring. Based on these analyses, an empirical statistical model was derived that was able to simulate daily streamflow trends sufficiently well. Analyses of subdaily streamflow changes provided additional insights. Finally, the present study supports many modelling approaches in the literature which found out that the main drivers of alpine streamflow changes are increased glacial melt, earlier snowmelt and lower snow accumulation in wintertime.}, language = {en} } @article{KothaWeatherillBindietal.2022, author = {Kotha, Sreeram Reddy and Weatherill, Graeme and Bindi, Dino and Cotton, Fabrice}, title = {Near-source magnitude scaling of spectral accelerations}, series = {Bulletin of earthquake engineering : official publication of the European Association for Earthquake Engineering}, volume = {20}, journal = {Bulletin of earthquake engineering : official publication of the European Association for Earthquake Engineering}, number = {3}, publisher = {Springer}, address = {Dordrecht}, issn = {1570-761X}, doi = {10.1007/s10518-021-01308-5}, pages = {1343 -- 1370}, year = {2022}, abstract = {Ground-motion models (GMMs) are often used to predict the random distribution of Spectral accelerations (SAs) at a site due to a nearby earthquake. In probabilistic seismic hazard and risk assessment, large earthquakes occurring close to a site are considered as critical scenarios. GMMs are expected to predict realistic SAs with low within-model uncertainty (sigma(mu)) for such rare scenarios. However, the datasets used to regress GMMs are usually deficient of data from critical scenarios. The (Kotha et al., A Regionally Adaptable Ground-Motion Model for Shallow Crustal Earthquakes in Europe Bulletin of Earthquake Engineering 18:4091-4125, 2020) GMM developed from the Engineering strong motion (ESM) dataset was found to predict decreasing short-period SAs with increasing M-W >= M-h = 6.2, and with large sigma(mu) at near-source distances <= 30km. In this study, we updated the parametrisation of the GMM based on analyses of ESM and the Near source strong motion (NESS) datasets. With M-h = 5.7, we could rectify the M-W scaling issue, while also reducing sigma(mu). at M-W >= M-h. We then evaluated the GMM against NESS data, and found that the SAs from a few large, thrust-faulting events in California, New Zealand, Japan, and Mexico are significantly higher than GMM median predictions. However, recordings from these events were mostly made on soft-soil geology, and contain anisotropic pulse-like effects. A more thorough non-ergodic treatment of NESS was not possible because most sites sampled unique events in very diverse tectonic environments. We provide an updated set of GMM coefficients,sigma(mu), and heteroscedastic variance models; while also cautioning against its application for M-W <= 4 in low-moderate seismicity regions without evaluating the homogeneity of M-W estimates between pan-European ESM and regional datasets.}, language = {en} } @article{KoussoroplisWacker2016, author = {Koussoroplis, Apostolos-Manuel and Wacker, Alexander}, title = {Covariance modulates the effect of joint temperature and food variance on ectotherm life-history traits}, series = {Ecology letters}, volume = {19}, journal = {Ecology letters}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {1461-023X}, doi = {10.1111/ele.12546}, pages = {143 -- 152}, year = {2016}, abstract = {Understanding animal performance in heterogeneous or variable environments is a central question in ecology. We combine modelling and experiments to test how temperature and food availability variance jointly affect life-history traits of ectotherms. The model predicts that as mean temperatures move away from the ectotherm's thermal optimum, the effect size of joint thermal and food variance should become increasingly sensitive to their covariance. Below the thermal optimum, performance should be positively correlated with food-temperature covariance and the opposite is predicted above it. At lower temperatures, covariance should determine whether food and temperature variance increases or decreases performance compared to constant conditions. Somewhat stronger than predicted, the covariance effect below the thermal optimum was confirmed experimentally on an aquatic ectotherm (Daphnia magna) exposed to diurnal food and temperature variance with different amounts of covariance.

About 80\% of annual precipitation over India occurs during the monsoon season from June through September. Next to its seasonal mean rainfall, the day-to-day variability is crucial for the risk of flooding, national water supply, and agricultural productivity. Here we show that the latest ensemble of climate model simulations, prepared for the AR-5 of the Intergovernmental Panel on Climate Change, consistently projects significant increases in day-to-day rainfall variability under unmitigated climate change. The relative increase by the period 2071-2100 with respect to the control period 1871-1900 ranges from 13\% to 50\% under the strongest scenario (Representative Concentration Pathways, RCP-8.5), in the 10 models with the most realistic monsoon climatology; and 13\% to 85\% when all the 20 models are considered. The spread across models reduces when variability increase per degree of global warming is considered, which is independent of the scenario in most models, and is 8\% +/- 4\%/K on average. This consistent projection across 20 comprehensive climate models provides confidence in the results and suggests the necessity of profound adaptation measures in the case of unmitigated climate change.}, language = {en} } @article{MummCzernitzkiBentsetal.2017, author = {Mumm, Rebekka and Czernitzki, Anna-Franziska and Bents, Dominik and Musalek, Martin}, title = {Socioeconomic situation and growth in infants and juveniles}, series = {Anthropologischer Anzeiger : journal of biological and clinical anthropology ; Mitteilungsorgan der Gesellschaft f{\"u}r Anthropologie}, volume = {74}, journal = {Anthropologischer Anzeiger : journal of biological and clinical anthropology ; Mitteilungsorgan der Gesellschaft f{\"u}r Anthropologie}, publisher = {Schweizerbart}, address = {Stuttgart}, issn = {0003-5548}, doi = {10.1127/anthranz/2017/0706}, pages = {101 -- 107}, year = {2017}, abstract = {Background: Physical growth of children and adolescents depends on the interaction of genetic and environmental factors e.g. diet and living conditions. Aim: We aim to discuss the influence of socioeconomic situation, using income inequality and GDP per capita as indicators, on body height, body weight and the variability of height and weight in infants and juveniles. Material and methods: We re-analyzed data from 439 growth studies on height and weight published during the last 35 years. We added year-and country-matched GDP per capita (in current US\$) and the Gini coefficient for each study. The data were divided into two age groups: infants (age 2) and juveniles (age 7). We used Pearson correlation and principal component analysis to investigate the data. Results: Gini coefficient negatively correlated with body height and body weight in infants and juveniles. GDP per capita showed a positive correlation with height and weight in both age groups. In infants the standard deviation of height increases with increasing Gini coefficient. The opposite is true for juveniles. A correlation of weight variability and socioeconomic indicators is absent in infants. In juveniles the variability of weight increases with declining Gini coefficient and increasing logGDP per capita. Discussion: Poverty and income inequality are generally associated with poor growth in height and weight. The analysis of the within-population height and weight variations however, shows that the associations between wealth, income, and anthropometric parameters are very complex and cannot be explained by common wisdom. They point towards an independent regulation of height and weight.}, language = {en} } @article{RottlerFranckeBuergeretal.2020, author = {Rottler, Erwin and Francke, Till and B{\"u}rger, Gerd and Bronstert, Axel}, title = {Long-term changes in central European river discharge for 1869-2016}, series = {Hydrology and Earth System Sciences}, volume = {24}, journal = {Hydrology and Earth System Sciences}, number = {4}, publisher = {Copernicus}, address = {G{\"o}ttingen}, issn = {1027-5606}, doi = {10.5194/hess-24-1721-2020}, pages = {1721 -- 1740}, year = {2020}, abstract = {Recent climatic changes have the potential to severely alter river runoff, particularly in snow-dominated river basins. Effects of changing snow covers superimpose with changes in precipitation and anthropogenic modifications of the watershed and river network. In the attempt to identify and disentangle long-term effects of different mechanisms, we employ a set of analytical tools to extract long-term changes in river runoff at high resolution. We combine quantile sampling with moving average trend statistics and empirical mode decomposition and apply these tools to discharge data recorded along rivers with nival, pluvial and mixed flow regimes as well as temperature and precipitation data covering the time frame 1869-2016. With a focus on central Europe, we analyse the long-term impact of snow cover and precipitation changes along with their interaction with reservoir constructions. Our results show that runoff seasonality of snow-dominated rivers decreases. Runoff increases in winter and spring, while discharge decreases in summer and at the beginning of autumn. We attribute this redistribution of annual flow mainly to reservoir constructions in the Alpine ridge. During the course of the last century, large fractions of the Alpine rivers were dammed to produce hydropower. In recent decades, runoff changes induced by reservoir constructions seem to overlap with changes in snow cover. We suggest that Alpine signals propagate downstream and affect runoff far outside the Alpine area in river segments with mixed flow regimes. Furthermore, our results hint at more (intense) rain-fall in recent decades. Detected increases in high discharge can be traced back to corresponding changes in precipitation.}, language = {en} }
