Ethnic discrimination has a negative impact on the socioemotional, behavioral, relational, and academic adjustment ofadolescents, while belonging with classmates, teachers, heritage, and national group may promote positive socioemotional and academicadjustment. We investigate (1) whether greater discrimination by peers and a lower sense of belonging with classmates, teachers, heritagegroup, and national group are associated with lower socioemotional and academic adjustment of adolescents of immigrant descent inGermany; and (2) whether a sense of belonging with these different sources acts as a protective factor lowering the negative effects ofdiscrimination on adjustment. Our sample included 439 7th-grade adolescents (51% female,Mage= 12.4 years) of immigrant descent from15 Berlin secondary schools. Results showed that higher discrimination was related to greater physiological stress, depressive symptoms,and disruptive school behavior. Higher heritage (but not national) identity, a higher sense of belonging with classmates and with teacherswere associated with better socioemotional and academic adjustment. An examination of interaction effects between discrimination andforms of belonging on adjustment revealed that, while the association between discrimination and poorer adjustment weakened for thosewith higher heritage identity, the association between discrimination and physiological stress increased for those with higher teacherrelatedness. We conclude that heritage identity (but not national identity or sense of belonging with classmates) can indeed be a protectivefactor against the negative effects of discrimination for adolescents of immigrant descent in Germany. Even though belonging with teachersmay exacerbate discrimination effects, further investigation with longitudinal data is needed. The findings underline the important role ofheritage ties among adolescents of immigrant descent as a source of adjustment, especially in light of discrimination experiences.
In recent years, nature-based solutions are receiving increasing attention in the field of disaster risk reduction and climate change adaptation as inclusive, no regret approaches. Ecosystem-based adaptation (EbA) can mitigate the impacts of climate change, build resilience and tackle environmental degradation thereby supporting the targets set by the 2030 Agenda, the Paris Agreement and the Sendai Framework. Despite these benefits, EbA is still rarely implemented in practice. To better understand the barriers to implementation, this research examines policy-makers' perceptions of EbA, using an extended version of Protection Motivation Theory as an analytical framework. Through semi-structured interviews with policy-makers at regional and provincial level in Central Vietnam, it was found that EbA is generally considered a promising response option, mainly due to its multiple ecosystem-service benefits. The demand for EbA measures was largely driven by the perceived consequences of natural hazards and climate change. Insufficient perceived response efficacy and time-lags in effectiveness for disaster risk reduction were identified as key impediments for implementation. Pilot projects and capacity building on EbA are important means to overcome these perceptual barriers. This paper contributes to bridging the knowledge-gap on political decision-making regarding EbA and can, thereby, promote its mainstreaming into policy plans.

Die neuere Literaturtheorie hat sich mit dem Sachverhalt auseinanderzusetzen, dass immer mehr zeitgenössische Erzähltexte durchgehend das Präsens nutzen, um zu erzählen. Das deutschsprachige Mittelalter kennt solche durchgängig im Präsens erzählenden Texte, also solche, die das ›narrative Präsens‹ verwenden, unserem Wissen nach nicht. Was es kennt, ist der punktuelle Gebrauch des Präsens in Texten, die ansonsten nahezu durchgängig im epischen Präteritum abgefasst sind, also ein Präsens, das oft als ›historisches‹ bezeichnet wird, das sich für das Mittelhochdeutsche jedoch besser als ›punktuelles Präsens‹ fassen lässt.
Die Verwendung eines solchen Präsens bildet den Gegenstand dieses Beitrages. Wir verfolgen dabei die Frage, wie sich dieser Tempusgebrauch narratologisch beschreiben lässt und welche Auswirkungen er auf die diegetische Struktur eines Erzähltextes hat.
Diese Frage, mag sie auch schlicht daherkommen, ist eine recht voraussetzungsreiche, erfordert sie doch zwei grundsätzliche Klärungen. Zunächst die nach der ganz allgemeinen Temporalität des Präsens. Was sagt das Präsens über die zeitliche Lagerung einer Aussage überhaupt aus? Außerdem berührt der Versuch, den Präsensgebrauch in Erzähltexten narratologisch zu beschreiben, auch die Frage, ob sich die Funktion von Tempora in narrativen und/oder fiktionalen Texten ändert oder ändern kann. Beides sind nicht nur umfassende und komplexe Fragen, sondern auch solche, die in der Forschung hochgradig umstritten sind. Unsere Überlegungen hierzu können angesichts dessen nur skizzenhaft und vorläufig sein.
Context:
Gyrochronology allows the derivation of ages for cool main sequence stars based on their observed rotation periods and masses, or a suitable proxy thereof. It is increasingly well-explored for FGK stars, but requires further measurements for older ages and K - M-type stars.
Aims:
We study the 2.7 Gyr-old open cluster Ruprecht 147 to compare it with the previously-studied, but far more distant, NGC 6819 cluster, and especially to measure cooler stars than was previously possible there.
Methods:
We constructed an inclusive list of 102 cluster members from prior work, including Gaia DR2, and for which light curves were also obtained during Campaign 7 of the Kepler/K2 space mission. We placed them in the cluster color-magnitude diagram and checked the related information against appropriate isochrones. The light curves were then corrected for data systematics using Principal Component Analysis on all observed K2 C07 stars and subsequently subjected to periodicity analysis.
Results:
Periodic signals are found for 32 stars, 21 of which are considered to be both highly reliable and to represent single, or effectively single, Ru 147 stars. These stars cover the spectral types from late-F to mid-M stars, and they have periods ranging from 6 d - 33 d, allowing for a comparison of Ruprecht 147 to both other open clusters and to models of rotational spindown. The derived rotation periods connect reasonably to, overlap with, and extend to lower masses the known rotation period distribution of the 2.5 Gyr-old cluster NGC 6819.
Conclusions:
The data confirm that cool stars lie on a single surface in rotation period-mass-age space, and they simultaneously challenge its commonly assumed shape. The shape at the low mass region of the color-period diagram at the age of Ru 147 favors a recently-proposed model which requires a third mass-dependent timescale in addition to the two timescales required by a former model, suggesting that a third physical process is required to model rotating stars effectively.
Controversy over the plate tectonic affinity and evolution of the Saxon granulites in a two- or multi-plate setting during inter- or intracontinental collision makes the Saxon Granulite Massif a key area for the understanding of the Palaeozoic Variscan orogeny. The massif is a large dome structure in which tectonic slivers of metapelite and metaophiolite units occur along a shear zone separating a diapir-like body of high-Pgranulite below from low-Pmetasedimentary rocks above. Each of the upper structural units records a different metamorphic evolution until its assembly with the exhuming granulite body. New age and petrologic data suggest that the metaophiolites developed from early Cambrian protoliths during high-Pamphibolite facies metamorphism in the mid- to late-Devonian and thermal overprinting by the exhuming hot granulite body in the early Carboniferous. A correlation of new Ar-Ar biotite ages with publishedP-T-tdata for the granulites implies that exhumation and cooling of the granulite body occurred at average rates of similar to 8 mm/year and similar to 80 degrees C/Ma, with a drop in exhumation rate from similar to 20 to similar to 2.5 mm/year and a slight rise in cooling rate between early and late stages of exhumation. A time lag ofc. 2 Ma between cooling through the closure temperatures for argon diffusion in hornblende and biotite indicates a cooling rate of 90 degrees C/Ma when all units had assembled into the massif. A two-plate model of the Variscan orogeny in which the above evolution is related to a short-lived intra-Gondwana subduction zone conflicts with the oceanic affinity of the metaophiolites and the timescale ofc. 50 Ma for the metamorphism. Alternative models focusing on the internal Variscan belt assume distinctly different material paths through the lower or upper crust for strikingly similar granulite massifs. An earlier proposed model of bilateral subduction below the internal Variscan belt may solve this problem.
"Left" and "right" coordinates control our spatial behavior and even influence abstract thoughts. For number concepts, horizontal spatial-numerical associations (SNAs) have been widely documented: we associate few with left and many with right. Importantly, increments are universally coded on the right side even in preverbal humans and nonhuman animals, thus questioning the fundamental role of directional cultural habits, such as reading or finger counting. Here, we propose a biological, nonnumerical mechanism for the origin of SNAs on the basis of asymmetric tuning of animal brains for different spatial frequencies (SFs). The resulting selective visual processing predicts both universal SNAs and their context-dependence. We support our proposal by analyzing the stimuli used to document SNAs in newborns for their SF content. As predicted, the SFs contained in visual patterns with few versus many elements preferentially engage right versus left brain hemispheres, respectively, thus predicting left-versus rightward behavioral biases. Our "brain's asymmetric frequency tuning" hypothesis explains the perceptual origin of horizontal SNAs for nonsymbolic visual numerosities and might be extensible to the auditory domain.
Bereits seit 2017 ist die außergerichtliche einvernehmliche Scheidung vor dem Notar in Griechenland zulässig. Es wird dazu ein Gesetz aus dem Jahr 2020 mit einigen Änderungen vorgestellt, die Anlass zu einem Gesamtüberblick der griechischen einvernehmlichen Scheidung geben. Einleitend wird auf die Historie des Gesetzes erklärend eingegangen. Folgende Themen- und Regelungsbereiche werden vertiefend erläuternd erörtert: Die außergerichtliche einvernehmliche Scheidung nach griechischem Recht (Vereinbarung der Ehegatten über die Auflösung ihrer Ehe - Bestätigung der Eheauflösung und Beurkundung durch den Notar - Eintragung der Scheidung in das Eheregister des zuständigen Standesamts); Schutz der Ehegatten und der gemeinsamen minderjährigen Kinder; Anerkennung der griechischen einvernehmlichen Scheidung in Deutschland (Geltung der Brüssel IIa-VO - Geltung der Brüssel IIb-VO); Geltung der Rom III-VO). Abschließend wird festgestellt: Die in Griechenland 2017 eingeführte einvernehmliche Scheidung unterliege mit Ausnahme des Konsenses der Ehegatten keinen weiteren materiellen Voraussetzungen. Allerdings sei es erforderlich, dass die Ehegatten Regelungen über die elterliche Sorge, den Umgang und den Unterhalt der gemeinsamen minderjährigen Kinder treffen. Dabei sei nicht immer sicher, dass zur Ermöglichung einer schnellen Scheidung das Wohl der Kinder stets bestmöglichst berücksichtigt werde. Auch berge die einvernehmliche Scheidung vor dem Notar familien-verögensrechtliche Gefahren. Hierzu wird näher ausgeführt.
