Drought threatens agroforestry landscapes and dryland livelihoods in a North African hotspot of environmental change
(2024-02-08)
Dryland agroforestry is often hailed as a nature-based solution for rural people’s water- and climate-related struggles, yet appraisals of traditional agroforestry practices and interventions in Maghreb countries are scant. In this study, we appraise whether and how agroforestry delivers as a solution to Moroccan farmers’ plight with drought. Through an analysis of landscape observations, 75 qualitative interviews, and six group discussions, we show that the region’s mountain residents risk losing their livelihoods ...

Weisfeiler-Lehman goes dynamic: An analysis of the expressive power of Graph Neural Networks for attributed and dynamic graphs
(2024-02-28)
Graph Neural Networks (GNNs) are a large class of relational models for graph processing. Recent theoretical studies on the expressive power of GNNs have focused on two issues. On the one hand, it has been proven that GNNs are as powerful as the Weisfeiler–Lehman test (1-WL) in their ability to distinguish graphs. Moreover, it has been shown that the equivalence enforced by 1-WL equals unfolding equivalence. On the other hand, GNNs turned out to be universal approximators on graphs modulo the constraints enforced by ...

Recovered memories in psychotherapy: a survey of practicing psychotherapists in Germany
(2024-01-29)
We report on a survey of 258 psychotherapists from Germany, focusing on their experiences with memory recovery in general, suggestive therapy procedures, evaluations of recovered memories, and memory recovery in training and guidelines. Most therapists (78%) reported instances of memory recovery encompassing negative and positive childhood experiences, but usually in a minority of patients. Also, most therapists (82%) reported to have held assumptions about unremembered trauma. Patients who held these beliefs were ...

Task-Level Checkpointing and Localized Recovery to Tolerate Permanent Node Failures for Nested Fork–Join Programs in Clusters
(2024-03-13)
Exascale supercomputers consist of millions of processing units, and this number is still growing. Therefore, hardware failures, such as permanent node failures, become increasingly frequent. They can be tolerated with system-level Checkpoint/Restart, which saves the whole application state transparently and, if needed, restarts the application from the saved state; or with application-level checkpointing, which saves only relevant data via explicit calls in the program. The former approach requires no additional ...

Universitäten und Hochschulen zwischen Beharrung und Reform
(Verlag Julius Klinkhardt, 2024-03)
Die Geschichte der Universitäten und Hochschulen ist seit dem Mittelalter durch ein so spannungsgeladenes wie fruchtbares Wechselspiel von Beharrung und Reform gekennzeichnet.
Dass diese ältesten Einrichtungen organisierter Wissensvermittlung bis heute existieren, hat mit ihrer Fähigkeit zu tun, die stets konkurrierenden konservativen und progressiven Elemente ihres Bildungsauftrags in der Regel gut ausbalancieren zu können.
Die im Band versammelten Beiträge untersuchen epochenübergreifend in bildungshistorischer ...

Examining the glottal stop as a mark of gender-inclusive language German
(2024-02-02)
Grammatical gender form influences readers’ mental gender representations. Previous research demonstrates that the generic masculine form leads to male-biased representations, while some alternative forms lead to female-biased representations. The present research examines the recently introduced glottal stop form in spoken language in German, where a glottal stop (similar to a short pause), meant to represent all gender identities, is inserted before the gender-specific ending. In two experiments (total N = 1188), ...

Maintain your mind, mantain your focus: Effects of focused attention and intensity in experienced runners
(2024-02-26)
The intensity that people choose for their endurance activities has a major influence on their affective experience. Furthermore, the direction of attention (e.g., internal or external) during endurance activities may significantly influence performance and ersonal perceptions. Therefore, in the current study, we focus on the interaction between intensity and attentional focus. We aim to address the question of whether adopting an internal (IAF; breathing) or an external attentional focus (EAF; environment), compared ...

Coherent acoustic phonons in a coupled hexagonal boron nitride-graphite heterostructure
(2024-02-14)
Femtosecond optically excited coherent acoustic phonon modes (CAPs) are investigated in a free-standing van der Waals heterostructure composed of a 20-nm transparent hexagonal boron nitride (hBN) and a 42-nm opaque graphite layer. Employing ultrafast electron diffraction, which allows for the independent evaluation of strain dynamics in the constituent material layers, three different CAP modes are identified within the bilayer stack after the optical excitation of the graphite layer. An analytical model is used to ...

Bedingungslose ambulante Erziehungshilfen
(2024-02-12)
„Bedingungslose Jugendhilfe“ ist die Bezeichnung für ein offenes politisches Reform- und sozialpädagogisches Forschungsprogramm, das sich gegen die Stigmatisierung von Nutzer_innen erzieherischer Hilfen stellt. In dem Programm wird der Frage nachgegangen, ob es erstrebenswert und praktisch umsetzbar wäre, wenn die Hilfen zur Erziehung unabhängig vom Vorliegen eines erzieherischen Bedarfs als universale Unterstützungsleistungen für alle Kinder, Jugendlichen und ihre Eltern attraktiv und zugänglich wären. Im vorliegenden ...

Bedingungslose Kinder- und Jugendhilfe
(2024-02-28)
Die Kinder- und Jugendhilfe gilt als öffentliche Infrastruktur der Erziehung und Bildung. Einer Inanspruchnahme von Hilfen zur Erziehung im Rahmen der KJH geht die Feststellung eines erzieherischen Bedarfs voraus. Demnach steht häufig eine Defizitdiagnose elterlicher Erziehung und Bildung am Beginn einer Hilfe, mit nicht selten stigmatisierender Wirkung. Der vorliegende Schwerpunkt beschäftigt sich mit den Perspektiven einer „Bedingungslosen Kinder- und Jugendhilfe“, womit nach den Möglichkeiten einer breiten und ...
