Hintergrund: Die Pilotstudie „Gesundheit und Unterstützung in Zeiten von Corona“ (Technische Universität Dortmund) erhob vom Mai bis Juli 2020 Veränderungen von Unterstützung und Wohlbefinden Älterer infolge der COVID-19-Pandemie. Ziel der Arbeit: Ziel war es, empirische Erkenntnisse zu den sozialen und mentalen Folgen der Pandemie für in Privathaushalten lebende Personen der Altersgruppe 40+ Jahre zu gewinnen. Betrachtet wurden durch die Pandemie bedingte Änderungen im Erhalt und im L...

Purpose: This work proposes an in-silico screening method for identifying promising formulation candidates in complex lipid-based drug delivery systems (LBDDS). Method: The approach is based on a minimum amount of experimental data for API solubilites in single excipients. Intermolecular interactions between APIs and excipients as well as between different excipients were accounted for by the Perturbed-Chain Statistical Associating Fluid Theory. The approach was applied to the in-silic...

The present study uses a quasi-experimental design to investigate the impact of team preferences on the accuracy of offside judgments. In Experiments 1 and 2, supporters of two German soccer clubs (i.e., Borussia Dortmund and FC Schalke 04) judged offsides in artificial scenes from a match between the clubs. We expected that supporters of both clubs would less frequently report the offside position of a forward from the preferred team. The results of Experiment 1 partly confirmed the predicti...

Joint academic–industrial projects supporting drug discovery are frequently pursued to deploy and benchmark cutting-edge methodical developments from academia in a real-world industrial environment at different scales. The dimensionality of tasks ranges from small molecule physicochemical property assessment over protein–ligand interaction up to statistical analyses of biological data. This way, method development and usability both benefit from insights gained at both ends, when predictivene...

Inwiefern der Besuch unterschiedlicher Schulformen Lernen und Bildungsverläufe beeinflusst, ist ein vieldiskutiertes Thema. Arbeiten zu Effekten der Schulformen für den Erfolg auf dem Arbeitsmarkt liegen jedoch bislang nur wenige vor. Hier setzt der vorliegende Beitrag an, in dem in einer längsschnittlichen Perspektive (N = 5292 Personen) überprüft wird, welche Effekte der Besuch unterschiedlicher Schulformen in der Sekundarstufe (vom Beginn der 7. Klasse) auf spätere berufliche Merkmale (Ber...

Engaging students in processes of mathematizing and active knowledge organization (instead of telling and rehearsing ready-made mathematics) is a key demand for high quality mathematics instruction. Although many mathematically rich context problems have been designed and published in textbooks, their impact on regular mathematics classrooms remains limited, as teachers face challenges in shaping and enacting the important phase of knowledge organization. The 15-year project KOSIMA presented ...

We present a realization of a fast interfacial Marangoni microswimmer by a half-spherical alginate capsule at the air–water interface, which diffusively releases water-soluble spreading molecules (weak surfactants such as polyethylene glycol (PEG)), which act as “fuel” by modulating the air–water interfacial tension. For a number of different fuels, we can observe symmetry breaking and spontaneous propulsion although the alginate particle and emission are isotropic. The propulsion mechanism i...

We consider autonomous integral functionals of the form F[u]:=∫Ωf(Du)dx where u:Ω→RN,N≥1, where the convex integrand f satisfies controlled (p, q)-growth conditions. We establish higher gradient integrability and partial regularity for minimizers of F assuming qp<1+2n−1, n≥3. This improves earlier results valid under the more restrictive assumption qp<1+2n.

In this work, we apply homodyne detection to investigate the frequency-resolved photon statistics of a cw light field emitted by a driven-dissipative semiconductor system in real time. We demonstrate that studying the frequency dependence of the photon number noise allows us to distinguish intrinsic noise properties of the emitter from external noise sources such as mechanical noise while maintaining a sub-picosecond temporal resolution. We further show that performing postselection on the re...

Alter(n)sgerechte Quartiersentwicklung unter Beachtung der Heterogenität des Alters Es ist sowohl ein politisches Ziel als auch der Wunsch älterer Menschen, möglichst lange selbstständig und selbstbestimmt im vertrauten Wohnumfeld leben zu können. Deshalb beschäftigen sich u.a. die Ökologische Gerontologie als auch multidisziplinäre Konzepte für die kommunale Praxis mit der Frage, wie gute Umwelten für das Altern bzw. alter(n)sgerechte Quartiere gestaltet sein sollten. In Anbetracht der zune...

New digital solutions are often lacking integration and acceptance by potential users. Therefore, only a small amount of innovative software solutions is really in use. The article describes a co-creation process by integrating end-users and relevant stakeholders right in the beginning in a social innovation process. Within this process, technology is seen as an enabler of innovation getting its relevance from new social practices of the people using it (e.g. working practices). Against the b...

Purpose: Research on the careers of fine-dining chefs is still underrepresented in the hospitality literature. Especially, there is a research gap in quantitative empirical evidence of answering the question of human, organizational, and motivational resources needed to become a top chef. The paper provides answers to the question which factors influence whether a chef will be awarded a Michelin star or not. Design/methodology/approach: Empirical evidence is given with the help of two quantit...

Auch hundert Jahre nach Max Webers Tod können Kommunikationswissenschaft und Journalismus noch von ihm lernen: Sein grundlegender Begriff des sozialen Handelns stützt Legitimität und Chancen realistischer Medienkritik; sein Konzept einer großen Presse-Erhebung blickt umfassender auf öffentliche Kommunikationsprozesse als spätere Formeln und Modelle; seine Ethik-Vorstellungen fördern eine zivilisierte Grundhaltung des Abwägens in Politik, Wissenschaft und Journalismus; seine auf Rationalitätsb...

The paper uses data from the combined TIMSS (Trends in International Mathematics and Science Study) and PIRLS (Progress in International Reading Literacy Study) assessment in 2011 to explore the subject-specific strengths and weaknesses among fourth grade students worldwide. Previous research came to the conclusion that students only differed in overall achievement levels and did not exhibit subject-specific strengths and weaknesses. This research did, however, not control for differences in ...

Residents of urban areas, and particularly urban cores, have higher levels of long-distance travel activity and related emissions, mostly on account of greater frequency of air travel. This relationship typically remains after controlling for basic socio-economic correlates of long-distance travel. There is an ongoing debate in the literature about what causes this association, and whether it calls into question urban densification strategies. Understanding this is important from a climate po...

Short glass fiber reinforced plastics (SGFRP) offer superior mechanical properties compared to polymers, while still also enabling almost unlimited geometric variations of components at large-scale production. PA6-GF30 represents one of the most used SGFRP for series components, but the impact of injection molding process parameters on the fatigue properties is still insufficiently investigated. In this study, various injection molding parameter configurations were investigated on PA6-GF30. T...

This dissertation describes a novel architecture and operational concept for a future electric power system. The architecture and operational concept were developed as a solution to the technical challenges which result from the ongoing decommissioning of conventional power plants and the mass scale integration of distributed and renewable energy sources. In particular, the architecture aims at ensuring the efficient, secure and stable operation of a future power system by enabling the coordi...

Ein-Fallen-Phänomene (STP) in nanoskaligen Transistor-Bauelementen besitzen herausragende Eigenschaften, die für viele nützliche und wichtige Anwendungen, einschließlich der Informationstechnologien und Biosensorik, vielversprechend sind. In dieser Doktorarbeit wurde ein neuartiger Biosensor-Ansatz vorgeschlagen und demonstriert, der auf der Überwachung von STP-Parametern als Funktion von Ziel Biomolekülen auf der Oberfläche von flüssigkeitsgesteuerten (LG) Silizium (Si) Nanodraht (NW) Feldef...
