Facilitating business model innovation: The influence of sustainability and the mediating role of strategic orientations
(2021-01-04)
Businesses increasingly incorporate the sustainability aspects into their products, services, and processes that drive innovation. While extant research on the linkage between sustainability and innovation has gained momentum over the past years, prior research has predominantly focused on sustainability's performance impacts (e.g., financially and environmentally) and product innovation outputs, neglecting the internal mechanisms that leverage sustainability. While findings from previous studies suggest that ...

Use of Design of Experiments (DoE) to Model the Sulphate Agent Amount of (Ultra)Finely Ground and Fast Hardening Portland Cement Clinker
(2021-09-25)
This paper presents a model to calculate the sulphate agent amount and sulphate agent ratio for fine grounded and fast hardening Portland cement clinker. Despite sufficient knowledge about the influence of calcium sulphate on the hydration process of cement, the sulphate agent amount is mostly adjusted empirically. As a result, often a wide and unfeasible experimental matrix has to be tested. In this work, Design of Experiments (DoE) was used in combination with in-situ X-ray diffraction (XRD) tests to accurately ...

Basteln, matschen und toben während der Coronakrise
(2021-11-26)
Mit der Sperrung von Spielplätzen und Parkanlagen bei zeitgleicher Schließung aller Einrichtungen der Kinderbetreuung zu Beginn der Coronapandemie wandelten sich Bedeutung und Nutzung des öffentlichen Raums. Maßnahmen und Empfehlungen wie das Abstandhalten, die Schließung von Schulen und Betreuungseinrichtungen und das Arbeiten von zu Hause veränderten den Kinder- und Familienalltag von einem Tag auf den anderen. Viele sonst alltäglich genutzte öffentliche Freiräume standen nicht mehr zur Verfügung; das „Austoben“ ...

Urm1, not quite a ubiquitin-like modifier?
(2021-09-09)
Ubiquitin related modifier 1 (Urm1) is a unique eukaryotic member of the ubiquitin-fold (UbF) protein family and conserved from yeast to humans. Urm1 is dual-functional, acting both as a sulfur carrier for thiolation of tRNA anticodons and as a protein modifier in a lysine-directed Ub-like conjugation also known as urmylation. Although Urm1 conjugation coincides with oxidative stress and targets proteins like 2-Cys peroxiredoxins from yeast (Ahp1) and fly (Prx5), it was unclear how urmylation proceeds molecularly and ...

Optical Quality of InAs/InP Quantum Dots on Distributed Bragg Reflector Emitting at 3rd Telecom Window Grown by Molecular Beam Epitaxy
(2021-10-21)
We present an experimental study on the optical quality of InAs/InP quantum dots (QDs). Investigated structures have application relevance due to emission in the 3rd telecommunication window. The nanostructures are grown by ripening-assisted molecular beam epitaxy. This leads to their unique properties, i.e., low spatial density and in-plane shape symmetry. These are advantageous for non-classical light generation for quantum technologies applications. As a measure of the internal quantum efficiency, the discrepancy ...

Different Visualizations Cause Different Strategies When Dealing With Bayesian Situations
(2020-08-21)
People often struggle with Bayesian reasoning. However, previous research showed that people’s performance (and rationality) can be supported by the way the statistical information is represented. First, research showed that using natural frequencies instead of probabilities as the format of statistical information significantly increases people’s performance in Bayesian situations. Second, research also revealed that people’s performance increases through using visualization. We have built our paper on existing ...

Perceptions of Vegan Food among Organic Food Consumers Following Different Diets
(2021-08-31)
This article identifies consumer segments for vegan food by analysing perceptions of vegan food among food organic consumers following different diets: vegans, vegetarians, former vegetarians, flexitarians, and omnivores. The analysis is based on responses to a quantitative consumer survey for which 503 participants were recruited from customers at German grocery stores by quota sampling according to diet and region. From the responses to an open-ended question eliciting the participants’ associations with vegan food, ...

Neither vitalist nor mechanist, neither dualist nor idealist: Plessner's third way
(2021-05-21)
The English translation of Helmuth Plessner’s (1892–1985) volume Levels of the Organic Life and the Human. An Introduction to Philosophical Anthropology (1928; henceforth: LO) finally fills in a long-lamented gap. An English translation already existed of other important essays by Plessner, such as Laughing and Crying: A Study of the Limits of Human Behaviour (1941; Eng. 1970); The Limits of Community. A Critique of Social Radicalism (1924; Eng. 1999); and more recently (in 2018) of Political Anthropology (originally ...

Full-scale testing of adhesively bonded timber-concrete composite beams
(2021-09-07)
This paper presents new findings on adhesively bonded timber-concrete composites with prefabricated concrete parts. Hereby, timber and concrete are bonded solely with adhesive and no metallic connectors have been used. Because the achievement of a continuous bond proved to be a critical point in past studies, special attention is given to that issue. The application procedure of the adhesives is investigated in small-scale bond samples and the manufacturing process in full-scale composite beams with a span of 8 m and ...

Vehicular Livestock Mobility in West Africa: Seasonal Traffic Flows of Cattle, Sheep, and Goats across Bamako
(2020-12-26)
Mali is a major livestock producing country in West Africa. However, in recent years, the sector has faced multiple challenges like farmer-herder conflicts, overuse of grazing and water resources, and the effects of climate change. Meanwhile, traditional livestock systems are becoming less important given the increased availability of vehicular transport for regional and international animal trade as well as new opportunities for more specialised urban and peri-urban production systems. To assess the role of Mali’s ...
