Neuorientierung für das Business-Coaching
(2021-08-16)
Ausgangspunkt der folgenden Beiträge ist die Arbeit „Coaching in der zweiten Romantik: Abstieg oder Aufstieg?“ von Böning und Strikker. Drei Autor/innen nehmen Stellung zu den Fragen: Welchen Einfluss kann Coaching auf den gesellschaftlichen und politischen Diskurs nehmen, um sowohl gesamtgesellschaftliche als auch politische Handlungsnotwendigkeiten aufzugreifen und dazu Stellung zu nehmen? Wie gestaltet Coaching organisationsbezogen kulturelle und politische Verhältnisse mit, wie sie die Autoren unter anderem in ...

Carbon dioxide and gaseous nitrogen emissions from biochar‐amended soils under wastewater irrigated urban vegetable production of Burkina Faso and Ghana
(2020-06-30)
To quantify carbon (C) and nitrogen (N) losses in soils of West African urban and peri‐urban agriculture (UPA) we measured fluxes of CO₂‐C, N₂O‐N, and NH₃‐N from irrigated fields in Ouagadougou, Burkina Faso, and Tamale, Ghana, under different fertilization and (waste‐)water regimes. Compared with the unamended control, application of fertilizers increased average cumulative CO₂‐C emissions during eight cropping cycles in Ouagadougou by 103% and during seven cropping cycles in Tamale by 42%. Calculated total emissions ...

Comparing the effects of generating questions, testing, and restudying on students' long‐term recall in university learning
(2020-01-21)
We compared the long‐term effects of generating questions by learners with answering questions (i.e., testing) and restudying in the context of a university lecture. In contrast to previous studies, students were not prepared for the learning strategies, learning content was experimentally controlled, and effects on factual and transfer knowledge were examined. Students' overall recall performance after one week profited from generating questions and testing but not from restudying. When analyzing the effects on both ...

The effect of environmental sustainability on credit risk
(2020-03-07)
The European Commission has proposed establishing a framework that redirects capital to sustainable investments in order to foster sustainable economic growth. A key proposal from this framework is the mandatory consideration of environmental criteria for investment decisions. However, in particular for bond investors, there is not much academic guidance on how to integrate sustainability criteria in the investment process. Hence, this study investigates the impact of environmental sustainability on the pricing of ...

Extension of Gap Bridgeability and Prevention of Oxide Lines in the Welding Seam through Application of Tools with Multi-Welding Pins
(2021-07-30)
Friction stir welding has become important in many areas of production and is increasingly used for joining aluminum components. For long welding seams, conventional tools with only one welding pin reach their technical limitations due to low gap bridgeability. When welding aluminum, the stirred in surface layers, such as oxides, lead to a decrease in static and dynamic strength since linear accumulations are formed in the welding seam. The aim of the present study is to increase the gap bridgeability using tools ...

Technological Frames in the Digital Age: Theory, Measurement Instrument, and Future Research Areas
(2021-05-21)
Digital technologies fuel technological change that generates substantial uncertainty and complexity. Corporate actors rely on their technological frames to cope with these challenges. Technological frames determine how actors interpret, assess, and shape a technology’s development, usage, and trajectory. However, the research fails to provide insights into the microfoundations that can explain the consequences of heterogeneity in technological frames. We argue that this research gap is due to a lack of a proper ...

No Robust Effect of Distributed Practice on the Short- and Long-Term Retention of Mathematical Procedures
(2020-04-29)
We investigated the effect of distributed practice and more specifically the “lag effect” concerning the retention of mathematical procedures. The lag effect implies that longer retention intervals benefit from longer inter-study intervals (ISIs). University students (N = 235) first learned how to solve permutation tasks and then practiced this procedure with an ISI of zero (i.e., massed), one, or 11 days. The final test took place after one or five weeks. All conditions were manipulated between-subjects. Contrary ...

The Role of Institutional Uncertainty for Social Sustainability of Companies and Supply Chains
(2020-04-06)
Global sourcing largely occurs from so-called emerging markets and developing economies (EMDEs). In these contexts, substantial leverage effects for sustainability in supply chains (SCs) can be expected by reducing adverse impacts on society and minimising related risks. For this ethical end, an adequate understanding of the respective sourcing contexts is fundamental. This case study of South Africa’s (SA) mining sector uses institutional theory and the notion of institutional uncertainty to empirically analyse the ...

Biomass Performance and Competition Effects in an Established Temperate Agroforestry System of Willow and Grassland—Results of the 2nd Rotation
(2020-11-19)
Agroforestry systems (AFSs) are promoted as environmentally friendly and climate-change-resilient cultivation systems with the potential of increasing ecosystem services. Especially under temperate climatic conditions, the implementation in agricultural practice is low so far, inter alia due to the lack of knowledge regarding longer-term effects of such systems. This study investigated biomass yields and crop development during the second rotation of an alley cropping system with willows (clone “Tordis” ((Salix ...
