The Dark Triad and Deception Perceptions
The present cross-sectional study (N = 205) tested the hypothesis that the Dark Triad traits – narcissism, Machiavellianism, and psychopathy – and the PID-5 maladaptive personality traits – Negative Affectivity, Detachment, Antagonism, Disinhibition, and Psychoticism – are associated with specific deception-related perceptions: perceived cue-based deception detectability, perceived deception production ability, and perceived deception detection ability. Participants completed personality and deception measures in an ...
Tailoring Phospholes for Imprint of Fluorescent 3D Structures
PMMA based polymer blends have been infused with luminescent phospholes and have been structured via nanoimprint. While symmetrically substituted phospholes are prone to crystallization and phase separation, structural modification of the phosphole backbone in the α‐ and β‐positions has been explored, which prevents these issues; a structural explanation for this is suggested. Best phase integrity has been obtained for β‐silyl‐substituted phospholes, which were implemented in thin films and beads. The emission ...
On the Evolution of Residual Stresses, Microstructure and Cyclic Performance of High-Manganese Austenitic TWIP-Steel after Deep Rolling
The mechanical properties and the near surface microstructure of the high-manganese twinning-induced plasticity (TWIP) steel X40MnCrAl19-2 have been investigated after deep rolling at high (200 ∘C ), room and cryogenic temperature using different deep rolling forces. Uniaxial tensile tests reveal an increase in yield strength from 400 MPa to 550 MPa due to surface treatment. The fatigue behavior of selected conditions was analyzed and correlated to the prevailing microstructure leading to an increased number of cycles ...
Influence of Surface Roughness on Pressure Drop in Two‐Phase Flow of Saturated Hydrocarbons
Pressure drop of propane and propylene in gas‐liquid saturation state are investigated for copper and mild steel test tubes. The surface structure of both tubes is determined with the focus variation method, yielding a six times higher roughness for the steel tube, although both tubes are manufactured in the same manner. In both tubes single phase pressure drop validation measurements are carried out and compared to known correlations. For two‐phase investigations both fluids are investigated at the reduced saturation ...
Bioeconomy from experts’ perspectives - Results of a global expert survey
Effective global collaboration is crucial to achieving the UN Sustainable Development Goals (SDGs). It requires an understanding of the needs of individual countries and their expectations related to bioeconomy. With the aim to explore the prospective developments in the global bioeconomy over the next 20 years, the German Bioeconomy Council, an independent advisory body to the German Federal Government, commissioned BIOCOM-AG to invite experts from around the globe to share their insights in a global expert survey. ...
Feeding practices of pre‐school children and associated factors in Kathmandu, Nepal
Background In developing countries such as Nepal, many children aged below 3 years do not grow at a sufficiently high rate and are vulnerable to micronutrient deficiencies (e.g. vitamin A). Challenges to child nutrition can result from poverty, unhealthy traditional practices, inadequate caring and feeding practices. The present study aimed to assess the feeding practices of pre‐school children and their associated factors. Methods A cross‐sectional study was carried out in pre‐schools located in Kathmandu ...
A simulation-based approach to evaluate objective material parameters from concrete rheometer measurements
Modern concretes such as ultra-high performance concrete (UHPC) show excellent strength properties combined with favorable flow properties. However, the flow properties depend strongly on process parameters during production (temperature, humidity etc.), but also change sensitively even with slight variations in the mixture. In order to ensure desired processing of the fluidlike material and consistent process quality, the flow properties of the concrete must be evaluated quantitatively and objectively. The usual ...
Candidates for photic entrainment pathways to the circadian clock via optic lobe neuropils in the Madeira cockroach
The compound eye of cockroaches is obligatory for entrainment of the Madeira cockroach's circadian clock, but the cellular nature of its entrainment pathways is enigmatic. Employing multiple‐label immunocytochemistry, histochemistry, and backfills, we searched for photic entrainment pathways to the accessory medulla (AME), the circadian clock of the Madeira cockroach. We wanted to know whether photoreceptor terminals could directly contact pigment‐dispersing factor‐immunoreactive (PDF‐ir) circadian pacemaker neurons ...
IMF‐World Bank Cooperation Before and After the Global Financial Crisis
This article adopts a diachronic view to compare patterns of institutional evolution of cooperation between the International Monetary Fund (IMF or Fund) and the World Bank (or Bank) before and after the global financial crisis. While the rules for Fund‐Bank cooperation had typically been tightened in response to crisis episodes, on balance they were loosened in the wake of the global financial crisis. Building on over 90 semi‐structured expert interviews and relevant official documentation, I argue that this new ...
The Long-Term Benefit of Video Modeling Examples for Guided Inquiry
Inquiry-based learning can be considered a critical component of science education in which students can assess their understanding of scientific concepts and scientific reasoning skills while actively constructing new knowledge through different types of activity levels (Klahr and Dunbar, 1988; Bell et al., 2005; Hmelo-Silver et al., 2007; Mayer, 2007). However, engaging in inquiry activities can be cognitively demanding for students, especially those with low prior knowledge of scientific reasoning skills (reasoning ...
