Sexuelle Inaktivität und sexuelle Unzufriedenheit bei Paaren in der mittleren Lebensphase nach im Mittel 31 Jahren Beziehungsdauer
(2024-04-30)
Theoretischer Hintergrund. Sexuelle Aktivität und Erleben verändern sich über die Lebensspanne. Unabhängig vom Alter ist ein reduziertes bzw. fehlendes sexuelles Verlangen die am häufigsten berichtete sexuelle Problematik. Es fehlen Studien an Paaren in langjährigen stabilen Partnerschaften. Fragestellung. Ziel war, die sexuelle Inaktivität und Unzufriedenheit von Paaren in der mittleren Lebensphase zu untersuchen. Methode. Es wurden Daten des 18-Jahres Follow-Ups der Längsschnittstudie „Zukunft Familie“ verwendet. ...

“Industry impacts more than nature” - Risk perception of natural hazards in more-than-human worlds
(2024-05-18)
Understanding the risk perceptions of natural hazards is vital for disaster mitigation. Despite extensive research on the topic, local and indigenous perspectives often remain marginalized and underrepresented. One reason discussed is the inherent Eurocentrism in knowledge production. Using narrative interviews with fishermen in the Patagonian fjord lands, we developed a grounded theory on risk perception against the background of actor–network theory to adress this criticism.
The emergent order of risk perception ...

Spatial and Temporal Variations of Stable Isotopes in Precipitation in the Mountainous Region, North Hesse
(2022-12-01)
Patterns of stable isotopes of water (¹⁸O and ²H) in precipitation have been used as tracers for analyzing environmental processes which can be changed by factors such as the topography or meteorological variables. In this study, we investigated the isotopic data in precipitation for one year in the low mountain range of North Hesse, Germany, and analyzed mainly for altitude, rainfall amount, and air temperature effects on a regional scale. The results indicate that the isotopic composition expressed an altitude ...

Electron beam powder bed fusion of Ti-30Ta high-temperature shape memory alloy: microstructure and phase transformation behaviour
(2024-06-19)
The present study reports on additive manufacturing of a Ti-30Ta (at.%) high-temperature shape memory alloy (HT-SMA) using electron beam powder bed fusion (PBF-EB/M) technique. Detailed microstructure analysis was conducted to reveal the microstructural evolution along the entire process chain, i.e. from gas-atomised powder to post-processed material. PBF-EB/M processed structures with near full density and an isotropic, β-phase stabilised microstructure, i.e. equiaxed β-grains of around 20 μm in diameter with no ...

Small villages and their sanitary infrastructure—an unnoticed influence on water quantity and a threat to water quality in headwater catchments
(2023-11-16)
In rural catchments, villages often feature their own, separate urban water infrastructure, including combined sewer overflows (CSOs) or wastewater treatment plants (WWTPs). These point sources affect the water quantity and quality of the receiving low order streams. However, the extent of this impact is rarely monitored. We installed discharge and water quality measurements at the outlet of two small, neighbouring headwater catchments, one that includes a village, a WWTP, and two CSOs, while the other is predominantly ...

Machine learning parameter systems, Noether normalisations and quasi-stable positions
(2024-06-25)
We discuss the use of machine learning models for finding “good coordinates” for polynomial ideals. Our main goal is to put ideals into quasi-stable position, as this generic position shares most properties of the generic initial ideal, but can be deterministically reached and verified. Furthermore, it entails a Noether normalisation and provides us with a system of parameters. Traditional approaches use either random choices which typically destroy all sparsity or rather simple human heuristics which are only ...

The impact of testosterone-lowering medication on recidivism in individuals convicted of sexual offenses
(2024-06-05)
Introduction: Treatment of individuals who have committed sexual offences with Testosterone-Lowering Medication (TLM) is a comparatively intrusive kind of intervention, which regularly takes place in coercive contexts. Thus, the question of efficacy, but also the question of who should be treated, when and for how long, are of great importance. Methods: Recidivism rates of TLM-treated high-risk individuals (þTLM; n¼54) were compared with high-risk individuals treated with psychotherapy only in the same forensic ...

Transformation and Leaching Simulation of 6:2 and 8:2 diPAP and Related Metabolites in Unsaturated Soil Column Studies with MACRO
(2023-10-14)
PFAS (perfluoroalkyl substances) are widespread in the environment and are found in almost every medium. Besides persistent PFAS, their transforming precursors gained attention since they may be a reservoir for persistent PFAS in soil. Only little information is available about the behavior of these precursors and the simultaneous leaching of their transformation products. However, this information is urgently needed to improve estimates of contamination levels. For this purpose, two precursors and their non-degradable ...

Exploring eco-industrial development in the global south: recognizing informal waste-picking as urban-industrial symbiosis?
(2023-05-23)
Industrial ecology (IE) is discussed as a suitable approach to resolve three widespread socio-ecological problems in the so-called global south: waste accumulation, unemployment, and lack of adequate housing. As the IE framework was developed mainly in the global north, its applicability in the global south is uncertain. The issue is discussed along the use of municipal waste as building materials as a concrete application of circular economy (CE) and IE principles, which could contribute to the alleviation of the ...

Effectiveness and context dependency of social norm interventions: five field experiments on nudging pro-environmental and pro-social behavior
(2024-06-26)
Social norm interventions hold the potential to change people’s behavior. Five field experiments (N = 1,163) examined the effects of a simple and easily realizable social norm nudge based on the social media format “Be like Bill.” The nudge consisted of a stick figure named Toni that communicated descriptive and injunctive norms regarding pro-environmental or pro-social behaviors. Nudge conditions were compared to no-intervention control conditions. Experiment 1 (N = 179) focused on paper towel consumption in a women’s ...
