Hybride Wissensarbeit
(2021-04-30)
Aufgrund der Fortschritte im Bereich der künstlichen Intelligenz (KI) ergeben sich neue Gestaltungsmöglichkeiten zur Reorganisation von Wissensarbeit an der Schnittstelle von Menschen und Maschine. Durch die Verschmelzung von menschlicher und künstlicher Intelligenz können komplementäre Stärken zum Lösen von Arbeitsaufgaben gebündelt werden. Neuartige Wissensarbeitssysteme sind erforderlich, die Wissensarbeitende sowohl bei der Ausübung von Routineaufgaben als auch Nichtroutineaufgaben unterstützen.

Öffnung - Schließung - Übertritte
(transcript Verlag, 2021)
Wer sich darum bemüht, die im Titel des vorliegenden Bandes genannten Koordinaten abzustecken, wird nicht umhinkommen, über jene Autorinnen und Autoren zu stolpern, die Mitte der 1990er Jahre die literarische Bühne des deutschsprachigen Raums betraten und deren Texte – gewollt oder ungewollt – marketingwirksam mit dem Etikett ›Popliteratur‹ und/oder ›literarisches Fräuleinwunder‹ versehen wurden. Die Arbeiten dieser neuen Generation junger Autorinnen und Autoren zelebrieren den »Genuß am Körper, am Realen« und dies ...

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“ ...

Investigating the Effect of Different Drying Strategies on the Quality Parameters of Daucus carota L. Using Dynamic Process Control and Measurement Techniques
(2021-03-21)
The present work aims to improve the understanding of the effect of different drying strategies at varying temperatures on the dynamic drying behaviour and quality of organic products such as carrots using non-invasive measurement techniques. For this purpose, carrot slices of 3 mm thickness were dried under three different strategies namely air temperature controlled (A), product temperature controlled (P) and stepwise temperature controlled (S) at different temperatures (50 °C, 60 °C and 70 °C) to measure and analyse ...

The Whole and the Parts—A New Perspective on Production Diseases and Economic Sustainability in Dairy Farming
(2021-08-12)
The levels of production diseases (PD) and the cow replacement rate are high in dairy farming. They indicate excessive production demands on the cow and a poor state of animal welfare. This is the subject of increasing public debate. The purpose of this study was to assess the effect of production diseases on the economic sustainability of dairy farms. The contributions of individual culled cows to the farm’s economic performance were calculated, based on milk recording and accounting data from 32 farms in Germany. ...

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 ...

Exploring Chinese Consumers’ Online Purchase Intentions toward Certified Food Products during the COVID-19 Pandemic
(2021-11-08)
The outbreak of COVID-19 has significantly increased consumers’ demands for online groceries, as well as healthy, safe, and better-quality food products. In China, certified food products are commonly perceived as safe and good-quality products. Therefore, this study investigated potential factors that influenced Chinese consumers’ online shopping intentions toward certified food during the COVID-19 crisis. An integrated model was proposed by combining the technology acceptance model (TAM) and the theory of planned ...

Seasonal effects in the long-term correction of short-term wind measurements using reanalysis data
(2021-11-21)
Measure–correlate–predict (MCP) approaches are often used to correct wind measurements to the long-term wind conditions on-site. This paper investigates systematic errors in MCP-based long-term corrections which occur if the measurement on-site covers only a few months (seasonal biases). In this context, two common linear MCP methods are tested and compared with regard to accuracy in mean, variance, and turbine energy production – namely, variance ratio (VR) and linear regression with residuals (LR). Wind measurement ...

New species and a new record of Phylloporia from Benin
(2021-04-23)
Species of the wood-decay genus Phylloporia (Hymenochaetaceae, Hymenochaetales, Basidiomycota) are widely distributed in the tropics. Phylloporia species are, however, morphologically and ecologically diverse, which makes morphology-based species identification challenging. In this study, we re-examined species of Phylloporia reported from Benin (West Africa). Using an integrative approach combining morphology, ecology, and phylogenetic analyses, we describe Phylloporia beninensis sp. nov. and report Phylloporia ...
