Performance, carcass quality and meat quality of the endangered German Angler Saddleback pig
(2024-04-30)
The Angler Saddleback pig is an endangered local breed originating from Germany. The breed is said to have low demands in terms of husbandry and feeding, and an excellent meat quality. To date, there is a lack of more recent scientific investigations of the breed. Therefore, 58 Angler Saddleback pigs were fattened in two consecutive trials whereby performance, carcass quality and meat quality were assessed. At an average age of 324 days, the pigs reached an average final live weight of 143 kg, an intramuscular fat ...

Influence of deep rolling at different temperatures on near-surface and mechanical properties of a Maraging C250 steel
(2024-04-27)
Due to an outstanding combination of high strength and fracture toughness Maraging steels are used in numerous industries, e.g., in the aerospace sector. The high strength can be attributed to precipitation strengthening by conventional age-hardening heat treatments. However, as many of the envisaged applications will suffer from cyclic loadings, the fatigue properties are of significant interest in terms of a reliable use. Generally, Maraging steels are characterized by a relatively low fatigue strength limiting the ...

Main soil microbial groups assessed by phospholipid fatty acid analysis of temperate alley agroforestry systems on crop- and grassland
(2024-01-12)
The phospholipid fatty acid (PLFA) composition of soils was analysed at three poplar-based silvo-arable systems and at one willow-based silvo-grassland alley agroforestry system in Central Germany. The objective was to analyse tree row effects on the PLFA composition of main fungal and main bacterial groups. The fungal groups were BAM (Basidiomycota + Ascomycota + Mucoromycota) and AMF (Arbuscular Mycorrhizal Fungi). The bacterial groups were Gram-negative, Firmicutes, and Actinobacteria. The total PLFA content varied ...

Psychotherapie wirkt
(2024-01-08)
Psychotherapie ist eine kooperative und individualisierte Behandlung zur Förderung der psychischen Gesundheit, die sich in (post-)modernen Gesellschaften weiterentwickelt. Psychotherapieerfolg umfasst ein breites Spektrum von Kriterien, wie beispielsweise die Verringerung von symptombezogenem Leidensdruck sowie die Förderung von Wohlbefinden, persönlichen Werten, Stärken und psychosozialer Partizipation. Es liegen umfangreiche metaanalytische Belege dafür vor, dass Psychotherapie bei den häufigsten psychischen Störungen ...

Die Rolle der Beratung in der gesellschaftlichen Transformation zu mehr Nachhaltigkeit
(2024-01-10)
Die Welt befindet sich im Umbruch, die Transformationsforschung (Umweltbundesamt 2017) nimmt dies auf und denkt soziale und ökologische Faktoren zusammen, um die Dichotomie zwischen Profit und Gemeinwohl zu hinterfragen. Die tiefgreifenden Veränderungen führen zu einer überarbeiteten Strategieberatung. Sie wird iterativer und stellt sich stärker auf disruptive Entwicklungen ein. Kunden und externe Partner werden früher und intensiver eingebunden. Obwohl es einen Zweig sich entwickelnder Beratung von Nachhaltigkeit ...

Universalist children’s services. From two-part to inclusive social infrastructure
(2024-01-11)
The scientific network “Universalist Children’s Services: From Two-Part to Inclusive Social Infrastructure,” funded by the German Research Foundation, comprises 20 researchers. Its purpose is to contribute to the development of a more inclusive design of the public children’s services system. To achieve this objective, the network integrates legal and educational perspectives in its analysis of the current structure of the children’s services system. The network’s starting point is the concept of universalist children’s ...

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 ...

High Consistency Silicone Rubber Foams
(2024-04-23)
Silicone elastomers are high-performance plastics. In the extrusion process, only high-consistency silicone rubbers were used. In order to reduce the cost and weight, silicone rubbers can be foamed during processing. In this study, high-consistency silicone rubber is processed with different physical and chemical blowing agents. The resulting reaction kinetics, as well as the mechanical and morphological properties, had been investigated and compared with each other. This showed that the chemical blowing agent ...

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 ...
