Published: March 2021

AbstractBird nests are specialized habitats because of their particular composition including nest detritus and bird droppings. In consequence, they attract a specialized arthropod community considered as nidicolous, which includes species only found in bird nests (strictly nidicolous) or sometimes found in bird nests (facultatively nidicolous). Because the factors influencing the entomofauna in bird nests are poorly understood, in autumn 2019, we collected nest material in 86 Barn Owl (Tyto alba) nest boxes. We investigated whether the invertebrate species richness was related to Barn Owl nest box occupancy, the density of available nest boxes and the landscape structure. We found 3,321 nidicolous beetle specimens belonging to 24 species. Species richness of strictly nidicolous beetles was 2.7 times higher in nest boxes occupied by a family of Barn Owls the previous spring compared to unoccupied nest boxes. It was also higher in sites that were more often occupied by Barn Owls in the five previous years and in areas surrounded by a higher proportion of crop fields. For facultatively nidicolous beetles, the density of Barn Owl nest boxes enhanced the species richness. In conclusion, our study suggests that the strictly nidicolous beetles benefit from occupied nest boxes of Barn Owls, whereas facultatively nidicolous beetles look for nest boxes independently of whether Barn Owls occupy them. Our study highlights the importance of bird nests for a suite of invertebrates.

AbstractThe potato cyst nematodes (PCN) Globodera rostochiensis and G. pallida are among the most important pests causing significant yield loss in potato production. Cultivating resistant cultivars of potato is the most effective and environmentally safe method for protecting potato crops against nematodes. However, widespread cultivation of cultivars resistant to G. rostochiensis can affect the reproduction of G. pallida. Therefore, breeding for resistance to nematodes remains among the major aims of potato breeding programmes. Many wild Solanum species could be valuable sources of nematode resistance. This study examined the resistance to G. pallida identified in two accessions of the wild species Solanum gourlayi. Both accessions demonstrated resistance to pathotypes Pa2 and Pa3, but show asymmetric distribution of resistance among the progeny clones. The presented distributions of resistance scores indicate quantitative nature of resistance to G. pallida. Furthermore, this resistance is specific to each pathotype and may be controlled by different genes. We also conclude that there is a need for independent evaluation of resistance for both pathotypes of G. pallida (Pa2 and Pa3).
The significance of climate variability on early modern European grain prices

Published: March 2021

AbstractGrain was the most important food source in early modern Europe (c. 1500–1800), and its price influenced the entire economy. The extent to which climate variability determined grain price variations remains contested, and claims of solar cycle influences on prices are disputed. We thoroughly reassess these questions, within a framework of comprehensive statistical analysis, by employing an unprecedentedly large grain price data set together with state-of-the-art palaeoclimate reconstructions and long meteorological series. A highly significant negative grain price–temperature relationship (i.e. colder = high prices and vice versa) is found across Europe. This association increases at larger spatial and temporal scales and reaches a correlation of$$-\,0.41$$-0.41considering the European grain price average and previous year June–August temperatures at annual resolution, and of$$-\,0.63$$-0.63at decadal timescales. This strong relationship is of episodic rather than periodic (cyclic) nature. Only weak and spatially inconsistent signals of hydroclimate (precipitation and drought), and no meaningful association with solar variations, are detected in the grain prices. The significant and persistent temperature effects on grain prices imply that this now rapidly changing climate element has been a more important factor in European economic history, even in southern Europe, than commonly acknowledged.
A descriptive phase model of problem-solving processes
Authors: Rott Benjamin , Specht Birte , Knipping Christine 
Published: March 2021

AbstractComplementary to existingnormativemodels, in this paper we suggest adescriptivephase model of problem solving. Real, not ideal, problem-solving processes contain errors, detours, and cycles, and they do not follow a predetermined sequence, as is presumed in normative models. To represent and emphasize the non-linearity of empirical processes, adescriptivemodel seemed essential. The juxtaposition of models from the literature and our empirical analyses enabled us to generate such adescriptivemodel of problem-solving processes. For the generation of our model, we reflected on the following questions: (1) Which elements of existing models for problem-solving processes can be used for a descriptive model? (2) Can the model be used to describe and discriminate different types of processes? Ourdescriptivemodel allows one not only to capture the idiosyncratic sequencing of real problem-solving processes, but simultaneously to compare different processes, by means of accumulation. In particular, our model allows discrimination between problem-solving and routine processes. Also, successful and unsuccessful problem-solving processes as well as processes in paper-and-pencil versus dynamic-geometry environments can be characterised and compared with our model.
Multi-attribute and Artificial Neural Network Analysis of Seismic Inferred Chimney-like Features in Marine Sediments: A Study from KG Basin, India
Authors: Ramu Rowtu , Sain Kalachand 
Published: March 2021

Abstract
In marine seismic sections, features like “chimneys”, characterized by low similarity chaotic zones or vertical disordered characteristics arise due to migration of gas. Numerous interpretation tools have been developed for the identification of chimney features from seismic data. Here, a study over a 2D seismic reflection profile, acquired by CSIR-National Geophysical Research Institute (NGRI), Hyderabad in the Krishna-Godavari (KG) basin in 2010 was carried out. The data is optimally conditioned or post-processed before extracting the attributes such as the similarity, dip variance, energy, and frequency washout, to capture the chimneys on seismic data. Finally, the attributes are combined and trained over interpreter’s acquaintances through a non-linear multi-layer perceptron (MLP) neural network to compute a hybrid attribute, defined as the chimney meta-attribute. The neural training results into an overall normalized root mean squared (RMS) error of 0.6 to 0.7 between the train and test data sets. Three chimneys of ~1.5, ~0.9, ~1.3 km heights are observed over the seismic line. As chimneys represent gas migration paths, the computation of chimney attribute helps in understanding the genesis of gas-hydrates not only in the KG basin, studied here, but also in any other prospective basin.
Sandstone Geochemistry of Dalbuing Formation of Yinkiong Group, Arunachal Pradesh, NE India: Implications for Provenance, Paleoweathering and Tectonic Settings
Authors: Mudoi Niku Moni , Gogoi Bikash , Dehingia Panchanan 
Published: March 2021

Abstract
This study presents the results of geochemical investigations of early to middle Eocene sandstones belonging to the Dalbuing Formation of Yinkiong Group, occurring in and around Yamne valley of Arunachal Pradesh. Geochemically, these sandstones are wacke and lithic arenite, with the former being dominant than the other. The various indices of weathering (CIA, CIW, PIA) suggest intense chemical weathering of the source rock. Moreover, the average Th/U ratio (mean = 6.97) also indicates intense chemical weathering in the source areas and derivation of the sediments from the upper continental crust. However, the plot of chemical index of alteration (CIA) vs. index of compositional variability (ICV) shows that most of the sandstones are geochemically mature and were derived from intensively weathered source rock. The sandstones were deposited dominantly in semi-arid condition. Tectonically, these sandstones are found to have affinities towards both the passive margin (PM) and the active continental margin (ACM) settings, which further implies existence of multiple tectonic activities during their deposition. Moreover, the elemental ratios of Eu/Eu*, La/Sc, Th/Sc, La/Co, Th/Co, Th/Cr and chondrite normalized REE distribution pattern suggest their derivation from sources of felsic composition. The high ratio of Zr/Sc indicates the enrichment of heavy mineral zircon supplemented by sediment recycling.

Published: March 2021

Abstract
Present study aims to understand the hydrochemical changes in proglacial meltwater stream emerging from the termini of Dokriani Glacier, central Himalaya, India. The major ion concentration of melt water between the years 1994-2015 has been reassessed to infer the glacial/subglacial weathering induced ionic release from Dokriani glacier system. The results from meltwater data collected during post-monsoon period (October 2015) shows that Ca2+ is more dominant cation followed by Mg2+, K+, Na+ and SO42− is most dominant anion followed by HCO3− and Cl-. Scatter plot between Ca2+ + Mg2+ vs total cations shows the overall dominance of carbonate weathering whereas Na++K+ vs total anions shows high positive relation suggesting domination of both carbonate and silicate weathering. By comparison, the ionic concentration for the year 2015 suggests a significant increase since 1994; however, the discharge weighted concentrations could provide more detailed estimates. An increasing trend in major cations viz. calcium (Ca2+) and magnesium (Mg2+) while the bicarbonate (HCO3−), sulphate (SO42−) and nitrogen (NO3-) has been observed as major anion. Further, the source of Cl-, NH4+, and NO3- in the meltwater stream is mainly derived from the atmospheric precipitation, anthropogenic, and weathering process. The process of carbonate weathering and dissolution of rock is ascertained as the one which regulates the melt water chemistry.

Abstract
Introduction
Promoting physical activity (PA) is a key strategy to prevent noncommunicable diseases worldwide. In order to monitor physical activity levels in Germany, several large-scale studies have reported on prevalence rates and correlates. However, a comprehensive analysis of correlates of PA over time is currently lacking for Germany.

Methods
For the analysis, 13 national cross-sectional data sets were utilized. Data analysis was restricted to respondents aged 18 and older. In a first step, data sets were kept separate in order to explore social gradients of PA and sport. In the second step, data sets were pooled, demographic factors harmonized and binary logistic regressions were conducted.

Results
Regarding sports participation, different data sets indicate comparable social gradients. People with a higher age, lower income, lower levels of education, or a migrant background consistently have a higher risk of not engaging in sports. Compared to sports participation, social gradients are less pronounced for engaging in vigorous PA. Higher age, lower education, and lower income are also markers for an increased risk of not engaging in vigorous PA.

Discussion
The study confirms that factors of age, income, education and migrant background continue to contribute to differentials in sport and vigorous PA participation in Germany. For policy-making, this implies that PA promotion should focus on systems-based actions that might reduce population-wide inequalities. Future research might focus on pooling single studies with smaller samples in order to investigate PA and sports participation in specific disadvantaged target groups.

SamenvattingHet doel van deze studie was om de rol van PSMA-PET/CT vast te stellen bij patiënten met biochemische persistentie (BCP) van prostaatkanker na robotgeassisteerde laparoscopische radicale prostatectomie (RALP). Geïncludeerd werden 150 patiënten met BCP na RALP, bij wie een PSMA-PET/CT-scan werd gemaakt. Een multivariabele logistische regressieanalyse werd uitgevoerd ter identificatie van voorspellers voor de detectie van metastasen buiten de prostaatloge (≥miN1) op PSMA-PET/CT. Bij 89/150 patiënten waren er aanwijzingen voor prostaatkanker buiten de prostaatloge (≥miN1). Een hogere PSA-waarde na RALP (p = 0,004) en een positieve pathologische lymfeklierstatus (p = 0,006) waren voorspellers voor PSMA-avide laesies buiten de prostaatloge. Het bleek dat bij een groot deel van de patiënten op de PSMA-PET/CT-scan met BCP na een RALP vanwege gelokaliseerd prostaatkanker, metastasen buiten de prostaatloge werden gezien. Hogere PSA-waarden en een positieve pathologische lymfeklierstatus waren significant geassocieerd met metastasen buiten de prostaatloge. De conclusie luidt dat bij patiënten met BCP een PSMA-PET/CT-scan is geïndiceerd om tot salvagebehandelbeslissingen te komen.
Intellectual Property Rights and Access in Crisis

Published: March 2021

AbstractThe importance of access to intellectual property rights (IPR) protected subject-matter in two crucial areas – public health, and educational and cultural engagement – has been extensively demonstrated during the COVID-19 pandemic. Although they involve separate legal areas, patent and copyright, the common thread linking the two is intellectual property's difficult relationship with access in the public interest. This paper examines the tensions caused by access barriers, the tools used to reduce them and their effectiveness. It is clear that the access barriers magnified by COVID-19 are not restricted to narrow or specific contexts but are widespread. They are created by, and are a feature of, our existing IPR frameworks. Open movements provide limited remedies because they are not designed to, nor can adequately address the wide range of access barriers necessary to promote the public interest. Existing legislative mechanisms designed to remove access barriers similarly fail to effectively remedy access needs. These existing options are premised on the assumption that there is a singular “public” motivated by homogenous “interests”, which fails to reflect the plurality and cross-border reality of the public(s) interest(s) underpinning the welfare goals of IPR. We conclude that a systemic re-evaluation is required and call for positive and equitable legal measures protective of the public(s) interest(s) to be built within IPR frameworks that also address non-IPR barriers. The current pandemic and development of a “new normal” provides a crucial opportunity to comprehensively consider the public(s) interest(s), not just during a global health crisis, but on an ongoing basis.
Something Scary Is Out There: Remembrances of Where the Threat Was Located by Preschool Children and Adults with Nighttime Fear
Authors: Coss Richard G. 
Published: March 2021

AbstractYoung children frequently report imaginary scary things in their bedrooms at night. This study examined the remembrances of 140 preschool children and 404 adults selecting either above, side, or below locations for a scary thing relative to their beds. The theoretical framework for this investigation posited that sexual-size dimorphism in Australopithecus afarensis, the presumed human ancestor in the Middle Pliocene, constrained sleeping site choice to mitigate predation. Smaller-bodied females nesting in trees would have anticipated predatory attacks from below, while male nesting on the ground would have anticipated attacks from their side. Such anticipation of nighttime attacks from below is present in many arboreal primates and might still persist as a cognitive relict in humans. In remembrances of nighttime fear, girls and women were predicted to select the below location and males the side location. Following interviews of children and adult questionnaires, multinomial log-linear analyses indicated statistically significant interactions (p < 0.001) of sex by location for the combined sample and each age class driven, in part, by larger frequencies of males selecting the side location and females selecting the below location. Data partitioning further revealed that males selected the side location at larger frequencies (p < 0.001) than the below location, whereas female selection of side and below locations did not differ significantly. While indicative of evolutionary persistence in cognitive appraisal of threat locations, the female hypothesis did not consider natural selection acting on assessment of nighttime terrestrial threats following the advent of early Homo in the Late Pliocene.
„Die Enkel der Osmanen“ – Ausgrenzung, Diskriminierung und Illegalisierung von „Tagelöhnern“ im Münchner Bahnhofsviertel
Authors: Atanisev Kaan , Haverkamp Rita 
Published: March 2021

ZusammenfassungIm Münchner Bahnhofsviertel gibt es eine „Tagelöhnerbörse“, die viel Unmut unter Anwohnenden und Gewerbetreibenden hervorruft. Die überwiegend aus Bulgarien stammenden „Tagelöhner“ sind dabei vielfältigen Ausgrenzungs- und Diskriminierungserfahrungen ausgesetzt, die zum Teil aus ihrer Angehörigkeit zu einer ethnischen Minderheit resultieren. Bei näherer Betrachtung zeigt sich allerdings, dass ihre ethnische Zugehörigkeit komplexer und vielschichtiger ist, als man auf den ersten Blick erahnt. Im Beitrag steht die Frage nach der Rolle der ethnischen Zugehörigkeit der „Tagelöhner“ im Mittelpunkt, um anhand ethnografischer Feldgespräche und Interviews die Aushandlungsprozesse von Zugehörigkeit im multiethnischen Bahnhofsviertel nachzuzeichnen. Nach einer Beschreibung der „Tagelöhner“ im Münchner Bahnhofsviertel wird die soziokulturelle Lage der ethnischen Minderheiten in Bulgarien dargestellt. Aus der von Uneindeutigkeit charakterisierten Zugehörigkeit der „Tagelöhner“ ergeben sich sowohl Vor- als auch Nachteile im Umgang mit den Gewerbetreibenden und Anwohnenden des Bahnhofsviertels. Abschließend wird die Illegalisierung der „Tagelöhnerbörse“ und deren Auswirkungen auf die Stellung der „Tagelöhner“ diskutiert.

AbstractInternet memes have become an increasingly pervasive form of contemporary social communication that attracted a lot of research interest recently. In this paper, we analyze the data of 129,326 memes collected from Reddit in the middle of March, 2020, when the most serious coronavirus restrictions were being introduced around the world. This article not only provides a looking glass into the thoughts of Internet users during the COVID-19 pandemic but we also perform a content-based predictive analysis of what makes a meme go viral. Using machine learning methods, we also study what incremental predictive power image related attributes have over textual attributes on meme popularity. We find that the success of a meme can be predicted based on its content alone moderately well, our best performing machine learning model predicts viral memes with AUC=0.68. We also find that both image related and textual attributes have significant incremental predictive power over each other.
A study of Phytophthora spp. in declining highbush blueberry in Germany reveals that P. cinnamomi can thrive under Central European outdoor conditions
Authors: Nechwatal Jan , Jung Thomas 
Published: March 2021

AbstractPhytophthora cinnamomiandP. cactorumwere detected in soil samples from aVaccinium corymbosumstand in southern Germany. Both species were virulent in an underbark inoculation assay and have not been reported from highbush blueberry in Germany before. WhileP. cactorumis a widely distributed species in nurseries and (semi)natural habitats like forests, field reports ofP. cinnamomiin Germany are rare due to its sensitivity to frost. Its occurrence in an outdoor blueberry stand indicates its potential to survive Central European winter periods that tend to be increasingly mild.Phytophthora cinnamomiwas also found in the substrate of youngV. corymbosumnursery plants, suggesting a high degree of contamination in commercial blueberry production and demonstrating the risk of spreading exotic invasive plant pathogens via planting of infested nursery stock.

AbstractConservation and improvement of water quality in water bodies is an important matter to maintain all of its uses as well as other human necessities like microclimate regulation and leisure. Lakes and reservoirs have a complex circulation behavior with vertical temperature profiles changes along the time, resulting in differences in water density and a vertical stratification condition. This characteristic can directly affect the water quality conditions perturbing its main indicators. This study aims to evaluate the quasi-3D models' capacity to represent the hydrodynamic behavior of a tropical lake and its effects on the main variables that characterize its water quality. To achieve this objective, high-frequency monitoring data were collected, the lake was represented in a quasi-3D model, and the accuracy of the result was evaluated by applying statistical indices. The evaluation showed good agreement between field measures and simulated results when compared with other applications. The connections between hydrodynamic behavior and water quality were seen with the simulations results analysis, which showed that mixing events and long stratification periods perturb the water quality, the first with re-suspended bed material and the second blocking the surface and bottom exchanges. The application of a 3D model gives the capacity to reproduce the reservoir spatial variability and its vertical profiles, which is necessary to study the constituents' distributions across the water column. Therefore, the hydrodynamic and water quality behavior of lakes was accurately represented by the model, as well as the importance of improving high-frequency monitoring techniques.
