Zum Forschungsstand über Ansätze des Dual Career Coachings
Der vorliegende Artikel zeigt den Forschungsstand zur Beratung von Dual Career Couples (DCCs) anhand von zehn theoretisch, empirisch und praxeologisch entwickelten Ansätzen auf. Zunächst wird die Bedeutung des Phänomens DCCs für die Karriereberatung konturiert und anschließend vor dem Hintergrund gesellschaftlicher Transformationsprozesse eingeordnet. Die Einführung eines triadisch konzeptualisierten Beratungsraums schafft einen Rahmen, der eine vergleichende Darstellung und Einordnung der zehn Ansätze ermöglicht. ...
Spiritual values shape taxonomic diversity, vegetation composition, and conservation status in woodlands of the Northern Zagros, Iran
Sacred groves are under-researched in Muslim countries so that their overall contribution to biodiversity conservation remains unknown. We studied 22 sacred groves and 45 surrounding woodlands in Northern Zagros, Iran, to compare taxonomic diversity, vegetation composition, and the conservation status of plant species. Sacred groves had higher taxonomic diversity and a more valuable species pool by sheltering numerous endangered plant species. Multivariate analysis indicated a substantial difference in the vegetation ...
Feed Quality and Feeding Level Effects on Faecal Composition in East African Cattle Farming Systems
Simple Summary Sub-Saharan cattle are often exposed to a feed reduction caused by a seasonal lack of forage, which was investigated in the first experiment. The supplementation of roughage-based diets with sweet potato vine silage and urea molasses blocks is recommended to improve the growth of heifers, in particular, which was investigated in the second experiment. Across all data, the fungal C/bacterial C ratio was positively related to nitrogen and negatively to neutral detergent fiber concentrations in feces. ...
Digital transformation: What we have learned (thus far) and what is next
There is certainly a lot of discussion about digital technologies, their transformative nature, and their potentially disruptive impact on business and society. The number of publications on digital technologies and their impact on business and management have risen dramatically. This paper's main objective is to draw attention to practical and research-related views on what we know and what we still need to learn about business and management in the digital era. We do so by combining the insights obtained from ...
Doppelspitzen: Notlösung, Heilsbringer oder innovatives Führungsmodell? Coaching für gelingende Führungstandems
Doppelspitzen werden in der aktuellen Führungsdebatte kontrovers diskutiert. Wissenschaftliche Erkenntnisse zur Arbeit von Führungstandems sind rar. Bisherige Coachingkonzepte befassen sich schwerpunktmäßig mit dem Konfliktcoaching von Doppelspitzen. In dem vorliegenden Beitrag wird den Fragen nachgegangen, welche Gelingensfaktoren und Herausforderungen es bei geteilter Leitung gibt und wie die Potenziale von Führungstandems durch (präventives) Coaching gehoben werden können.
Soil microbial properties of subalpine steppe soils at different grazing intensities in the Chinese Altai Mountains
Long-term provision of ecosystem services by grasslands is threatened by increasing stocking densities. The functions of grassland ecosystems depend on a mutual relationship between aboveground and belowground biota. While the effects of increasing stocking density on plant biomass are well studied, little is known about its impact on soil microbial properties. To fill this knowledge gap a grazing experiment was conducted on a summer pasture in the Chinese Altai Mountains during the summers of 2014 and 2015 using a ...
Extended life cycle assessment reveals the spatially-explicit water scarcity footprint of a lithium-ion battery storage
The life cycle water scarcity footprint is a tool to evaluate anthropogenic contributions to regional water scarcity along global supply chains. Here, we complement it by a classification of the risk from human water use, a comprehensive conceptualisation of water use and a spatially-explicit impact assessment to a midpoint approach that assesses the risk of on-site and remote freshwater scarcity. For a 2 MWh Lithium-ion battery storage, the quantitative Water Scarcity Footprint, comprising physically used water, ...
Modelling stress‐state dependent nonlocal damage and failure of ductile metals
Damage and failure of ductile metals is highly influenced by the stress state. In fact, void growth takes place under hydrostatic tensile loading and void coalescence leads eventually to ductile failure. A completely different damage mechanism occurs for shear dominated loading that results in void elongation within a narrow shear band. In order to account for both failure mechanisms, a stress state dependent damage model is proposed. The model is based on a continuum damage mechanics approach, whereby nonlinear ...
Damage modelling for the lifetime prediction of structural adhesive joints subjected to hygro‐thermo‐mechanical long‐term loading
A damage model is presented for the lifetime prediction of structural adhesive joints under hygro‐thermo‐mechanical loading. The damage approach is applied through a cohesive zone model together with the concept of effective stress. It consists of a temperature‐dependent creep and hygro damage evolution due to mechanical loading and chemical aging, caused by the local water concentration. The creep damage part considers multiaxiality of the loading by an equivalent stress. The model parameters are identified by means ...
Role of Nanoimprint Lithography for Strongly Miniaturized Optical Spectrometers
Optical spectrometers and sensors have gained enormous gimportance in metrology and information technology, frequently involving the question of size, resolution, sensitivity, spectral range, efficiency, reliability, and cost. Nanomaterials and nanotechnological fabrication technologies have huge potential to enable an optimization between these demands, which in some cases are counteracting each other. This paper focuses on the visible and near infrared spectral range and on five types of optical sensors (optical ...
