Using Spacing to Promote Lasting Learning in Educational Contexts. Promises and Challenges.
(2022-12-12)
Spacing repeated study phases across multiple sessions instead of studying and restudying the learning material in one session only is an effective strategy to promote lasting learning. However, most studies demonstrating the spacing effect were conducted in the laboratory, using simple verbal material. Learning in educational contexts differs regarding the complexity and coherence of the learning material and concerning the role of motivational and affective learner characteristics. Studies conducted in educational ...

The Thermodynamic Stability of Membrane Proteins in Micelles and Lipid Bilayers Investigated with the Ferrichrom Receptor FhuA
(2022-05-13)
Extraction of integral membrane proteins into detergents for structural and functional studies often leads to a strong loss in protein stability. The impact of the lipid bilayer on the thermodynamic stability of an integral membrane protein in comparison to its solubilized form in detergent was examined and compared for FhuA from Escherichia coli and for a mutant, FhuAΔ5-160, lacking the N-terminal cork domain. Urea-induced unfolding was monitored by fluorescence spectroscopy to determine the effective free energies ...

Was unterscheidet Führung in Präsenz vom virtuellen Raum?
(2022-09-05)
Die Diskussion über Führung in Präsenz und in der virtuellen Welt hat durch die Covid19 bedingte Verlagerung von Arbeitsplätzen in die Homeoffices neuen Schwung aufgenommen. Jedoch muss in die Diskussion miteinfließen, wie und wodurch Führung wirksam wird. Kommunikation auf sachlicher, affektiver und emotionaler Ebene ist das Bindeglied zwischen Führungskraft und Geführten. Aber gerade Kommunikation unterscheidet sich grundlegend in Präsenz und im virtuellen Raum. Das Kommunikationsmodell von Owen Hargie beschreibt ...

Complementary decompositions of monomial ideals and involutive bases
(2022-06-25)
Complementary decompositions of monomial ideals - also known as Stanley decompositions - play an important role in many places in commutative algebra. In this article, we discuss and compare several algorithms for their computation. This includes a classical recursive one, an algorithm already proposed by Janet and a construction proposed by Hironaka in his work on idealistic exponents. We relate Janet’s algorithm to the Janet tree of the Janet basis and extend this idea to Janet-like bases to obtain an optimised ...

Social representation of nonacademic work from the perspective of company gatekeepers in the Mexican tourism sector
(2022-11-22)
Cooperations or transfers of the German technical and vocational education and training (TVET) system have taken place in different cultural contexts in recent decades. In Mexico, the so-called Modelo Méxicano de Formación Dual has been adapted to Mexico's cultural conditions. Yet, it still seems to be largely unknown in society, the education system and the labour market. Attitudes, perceptions or so-called ‘social representations’ are culturally anchored in a society and can be identified in artefacts and individual ...

Die Berliner Stadtreinigung (BSR) auf dem Weg ins „Neue Normal“ - Eine Fallstudie
(2022-11-17)
Die COVID-19-Pandemie war der größte Transformationsbeschleuniger für die Arbeitsorganisation. Die BSR hat in einer repräsentativen Studie 2374 Beschäftigten zu Erfahrungen und Erwartungen mit mobilen Arbeiten (MoA) befragt. Es konnten keine unterschiedlichen Erwartungen bei Beschäftigten verschiedener Verwaltungsbereiche oder unterschiedlicher Altersgruppen nachgewiesen werden. Auch die familiäre Situation führt zu keinen anderen Erwartungen an das MoA. Führungskräfte wünschen sich weniger MoA. Die meisten wollen 2 ...

Microstructural Influences Caused by Different Aging Strategies on the Strain-Dependent Damping of the High-Strength Aluminum Alloy AA7075
(2022-12-16)
The present study focused on the influence of different aging conditions on the strain-dependent damping of the high-strength aluminum alloy AA7075. For this purpose, different artificial aging strategies were carried out after solution heat treatment with subsequent water quenching to identify correlations between microstructural evolution, hardness development, and individual material damping. The resulting material damping was measured using an experimental setup based on the principle of electromagnetic feedback. ...

Virtuelles Arbeiten, Führung auf Distanz
(2022-11-10)
Seit inzwischen mehr als drei Jahrzehnten haben sich im Zuge der Digitalisierung völlig neue, virtuelle Kommunikationsformen herausgebildet. Vieles ist Wirklichkeit geworden, was zuvor im Bereich der Sciencefiction angesiedelt schien. Die Etablierung der digitalen Kommunikationsmedien bedeutet dabei nicht nur die Erschließung zusätzlicher Kommunikationskanäle. Es handelt sich nicht nur um veränderte Formen und Wege des Realitätszugangs. Durch die Verschränkung der analogen mit der virtuellen Welt entsteht etwas völlig ...

Two sorts of natural history: On a central concept in critical theory and ethical naturalism
(2022-06-13)
The concept of natural history has received a great deal of attention in contemporary practical philosophy, especially as a result of Michael Thompson's concept of natural-historical judgments which aims to explain the normativity of the human life-form. With this concept, the norms effective in a life-form are understood as something natural and constitutive for that life-form. Although Thompson does not present a historical-philosophical model, he claims to be able to determine the normativity of the historically ...

Antecedents to the Adoption of Mobile Payment in China and Italy: an Integration of UTAUT2 and Innovation Resistance Theory
(2022-01-22)
This research aims to investigate the adoption gap in mobile payment systems between Italy and China, focusing on users’ intention to adopt mobile payment. The theoretical framing considers both drivers and barriers when combines the unified theory of acceptance and use of technology 2 (UTAUT2) with innovation resistance theory (IRT). To empirically verify the proposed model, this study gathers primary data through a web-based, self-administered survey. To analyze the data, we use structural equation modeling, and ...
