Das Wohlbefinden von Kindern als elterliches Konstrukt
(2022-07-03)
Der Beitrag beschäftigt sich mit der Perspektive von Eltern auf das Wohlbefinden ihrer Kinder unter dem Eindruck der pandemiebedingten Schließungen von Kindertageseinrichtungen. Auf Basis qualitativ-rekonstruktiver Analysen kann gezeigt werden, wie sich die Wahrnehmungen der eigenen und der kindlichen Handlungsmächtigkeit bedingen. In Verbindung mit der Verfügbarkeit des Zugangs zur sog. Notbetreuung beeinflusst dieses Verhältnis das Belastungserleben.

Multi-Task Autoencoders and Transfer Learning for Day-Ahead Wind and Photovoltaic Power Forecasts
(2022-10-30)
Integrating new renewable energy resources requires robust and reliable forecasts to ensure a stable electrical grid and avoid blackouts. Sophisticated representation learning techniques, such as autoencoders, play an essential role, as they allow for the extraction of latent features to forecast the expected generated wind and photovoltaic power for the next seconds up to days. Thereby, autoencoders reduce the required training time and the time spent in manual feature engineering and often improve the forecast ...

Redoxtrons – An experimental system to study redox processes within the capillary fringe
(2023-02-02)
Spatiotemporal characterisation of the soil redox status within the capillary fringe (CF) is a challenging task. Air-filled porosities (ε), oxygen concentration (O₂) and soil redox potential (Eₕ) are interrelated soil variables within active biogeochemical domains such as the CF. We investigated the impact of water table (WT) rise and drainage in an undisturbed topsoil and subsoil sample taken from a Calcaric Gleysol for a period of 46 days. We merged 1D (Eₕ and matric potential) and 2D (O₂) systems to monitor at ...

Analysis and Validation of Varied Simulation Parameters in the Context of Thermoplastic Foams and Special Injection Molding Processes
(2023-04-28)
The simulation solutions of different plastic injection molding processes are as multifaceted as the field of injection molding itself. In this study, the simulation of a special injection molding process, which generates partially foamed integral components, was parameterized and performed. This partial and physical foaming is realized by a defined volume expansion of the mold cavity. Using the injection molding simulation software Moldex 3D, this so-called Pull and Foam process was digitally reconstructed and ...

Model selection, adaptation, and combination for transfer learning in wind and photovoltaic power forecasts
(2023-03-14)
There is recent interest in using model hubs – a collection of pre-trained models – in computer vision tasks. To employ a model hub, we first select a source model and then adapt the model for the target to compensate for differences. There still needs to be more research on model selection and adaption for renewable power forecasts. In particular, none of the related work examines different model selection and adaptation strategies for neural network architectures. Also, none of the current studies investigates the ...

High Buffering Potential of Winter Wheat Composite Cross Populations to Rapidly Changing Environmental Conditions
(2023-06-20)
A winter wheat composite cross population (CCP), created in the UK in 2001, has been grown in Germany, Hungary, and the UK since 2005 (F5 generation). In 2008/09 (F8), a cycling pattern for the populations was developed between partners to test the effects of rapidly changing environments on agronomic performance and morphological characteristics. One CCP was grown by eight partners for one year and subsequently sent to the next partner, creating “cycling CCPs” with different histories. In 2013, all eight cycling ...

Orchard meadows: consumer perception and communication of a traditional agroforestry system in Germany
(2023-03-23)
Europe has a large variety of historic cultural agroforestry systems which provide numerous ecosystem services. Traditional agroforestry landscapes are characterized by a high level of biodiversity, but they lack an economic basis due to considerable time and financial effort required for cultivation, maintenance, and harvesting. Orchard meadows (OM) are a typical example for agroforestry systems. They combine large fruit trees with undercropping or livestock raising. This study investigates consumer knowledge and ...

Anonymisierung von Patientendaten durch Fremdlabore für Dritte
(2023-05-25)
Medizinische Diagnostik findet oft in einem Netzwerk statt. Proben oder Gesundheits(roh)daten werden von Ärztinnen und Ärzten erhoben und von diesen an Fremdlabore zur Diagnostik weitergeleitet. Diese Labore bedienen sich dann oft weiterer Dienste, um Verfahren zu beschleunigen oder Ergebnisse zu verbessern (Dritte). Der Beitrag betrachtet die datenschutzrechtlichen Implikationen dieses Vorgehens aus der Perspektive eines Fallbeispiels aus der Blutbildanalyse (I.) und eines entsprechenden Systemsaufbaus zur ...

Influence of blend proportion and baking conditions on the quality attributes of wheat, orange‑fleshed sweet potato and pumpkin composite flour dough and bread: optimization of processing factors
(2023-02-16)
Orange-fleshed sweet potato (OFSP) and pumpkin fruit are underutilized crops with great potential for the production of high-quality bread with health-enhancing properties. However, the incorporation of nonconventional flour in bread formula may influence the dough and bread quality properties. This study investigated the effect of partial substitution of wheat flour with OFSP (10–50%) and pumpkin flour (10–40%), baking temperature (150–200 °C) and baking time (15–25 min) on the quality properties of the composite ...
Rezension
[Rezension zu:] Imbusch, Peter (Hrsg.): Soziologie der Hinterhältigkeit. Weinheim/Basel: Beltz Juventa 2021. 364 Seiten. ISBN: 978-3-7799-6548-0. Preis €29.95.
(2023-03-23)
Hinterhältigkeit wird alltäglich mit Haltungen wie Arglist, Gemeinheit, Falschheit, Niedertracht oder Tücke und mit entsprechend verpönten Handlungsorientierungen assoziiert, was mit eindeutigen moralischen Verurteilungen verbunden ist. Zu dieser selbstverständlich wirkenden normativen Einordnung heben Peter Imbusch und Joris Steg in ihrem einleitenden Beitrag des Sammelbandes den Widerspruch hervor, dass hinterhältiges Verhalten trotz seiner negativen Konnotation „ein häufig vorkommendes, alltägliches Phänomen“ (S. ...
