Differenzierung und Professionalisierung der personenbezogenen Beratungsformate
(2021-04-22)
Die Diskussion über den Stand der Professionalisierung und sowie über den Professionsanspruch personenbezogener Prozessberatung begleitet die fachliche Entwicklung der Beratung von ihren Anfängen an. Dabei hat sich diese Beratungsform inzwischen so erfolgreich etabliert, dass auch klassische Unternehmensberatungsfirmen, die ihre Dienstleistung vormals ausschließlich auf der Basis betriebswirtschaftlicher und juristischer Expertise anboten und großen Wert auf Distanz zu psychologisch orientierten Ansätzen legten, ...

Exploring external factors affecting the intention-behavior gap when trying to adopt a sustainable diet: a think aloud study
(2021-02-19)
Not least from an ecological and health perspective, it can be posited that a broader part of consumers should practice sustainable diets. People who are already willing to do so are often confronted with the intention-behavior gap, caused by a range of internal and external factors. To eliminate these barriers requires a deeper and more comprehensive understanding of these factors and their interplay. Therefore, a think aloud study with 20 adult German participants was conducted to explore the four chosen external ...

Automatic Assessment of Keel Bone Damage in Laying Hens at the Slaughter Line
(2021-01-12)
Simple Summary
Keel bone damage (KBD) is very prevalent in commercial laying hen flocks with a wide range of affected hens/flock. It can cause pain, and affected hens have been found to be less mobile. The assessment of this animal welfare indicator provides important feedback for the farmer about flock health and consequently on the need for interventions. However, the assessment of keel bone damage is time-consuming, and prior training is needed in order to gain reliable results. Optical detection methods can be ...

Geheimnisse in der Supervision von Psychotherapeut/innen in Ausbildung und Motive dafür
(2021-06-01)
Geheimnisse sind omnipräsent: 97 % der Menschen haben mindestens ein Geheimnis, von dem niemand weiß. Die allgemeine Geheimnisforschung hat in den letzten Jahren zugenommen, fehlt aber noch im Supervisionsbereich. In einer anonymisierten Online-Befragung von Psychotherapeut/innen in Ausbildung (PiA) zeigte sich: Die häufigsten Geheimnisse in der Supervision sind, dass die Supervision keine Hilfe ist, die PiAs sich nicht ernst genommen fühlen und dass sich die Konzeptionen von PiAs von denen ihrer Supervisor/innen ...

Recent Developments in the Field of Modified Patankar-Runge-Kutta-methods
(2021-12-14)
Modified Patankar-Runge-Kutta (MPRK) schemes are numerical one-step methods for the solution of positive and conservative production-destruction systems (PDS). They adapt explicit Runge-Kutta schemes in a way to ensure positivity and conservation of the numerical approximation irrespective of the chosen time step size. Due to nonlinear relationships between the next and current iterate, the stability analysis for such schemes is lacking. In this work, we introduce a strategy to analyze the MPRK22(α)-schemes in the ...

Effects of mucilage concentration at different water contents on mechanical stability and elasticity in a loamy and a sandy soil
(2021-10-26)
Mucilage released by plant roots affects hydrological and mechanical properties of the rhizosphere. The aim of this study was to disentangle the effects of the factors mucilage and soil moisture on a range of soil mechanical parameters in a sand and a loam. Both substrates were homogenised and filled into cylinders at bulk densities (ρb) of 1.26 and 1.47 g cm−³ for loam and sand, respectively. Chia seed (Salvia hispanica L.) mucilage concentrations of 0, 0.02, 0.2 and 2 g dry mucilage kg−¹ dry soil were tested at ...

Synthesis, Structure and Cu-Phenylacetylide Coordination of an Unsymmetrically Substituted Bulky dppf-Analog
(2021-12-03)
The donor properties of a set of bulky ferrocene based bisphosphanes (Fe(C₅H₄PMes₂)₂ and (C₅H₄PMes₂)Fe(C₅H₄PᵗBu₂ with Mes= mesityl and ᵗBu=tert-butyl) were probed by exploring the NMR parameters of the corresponding selenophosphoranes amended by cyclovoltammetry. The ligand properties were explored in the complexation of copper phenylacetylide which is relevant as intermediate in the Cu(I) catalyzed CO₂ addition to phenylacetylene. Owing to the poor solubility of the resulting complexes their characterization was ...

CLeaR: An adaptive continual learning framework for regression tasks
(2021-07-16)
Catastrophic forgetting means that a trained neural network model gradually forgets the previously learned tasks when being retrained on new tasks. Overcoming the forgetting problem is a major problem in machine learning. Numerous continual learning algorithms are very successful in incremental learning of classification tasks, where new samples with their labels appear frequently. However, there is currently no research that addresses the catastrophic forgetting problem in regression tasks as far as we know. This ...

On a hybrid approximation concept for self-excited periodic oscillations of large-scale dynamical systems
(2021-12-14)
When approximating periodic solutions in the context of large-scale dynamical systems involving strong local nonlinearities, efficiency is of special interest. Hence, the literature suggests a combination of two approximation methods for increasing the ratio of computational cost to accuracy. Within this contribution, a combination of Finite Difference and Harmonic Balance method is proposed. Due to the usage of Harmonic Balance it is shown, that the resulting equations only depend on the degrees of freedom that are ...

Resolving the base of the pyramid inclusion paradox through supplier development
(2021-05-16)
Resulting from divergent business environments between actors, the integration of the base of the pyramid (BoP) into formal supply chain (SC) structures is often hampered by institutional voids, which can result in the emergence of paradoxical situations. This paper analyzes the potential of supplier development (SD) for addressing the BoP inclusion paradox. The study develops a framework based on the assumption that SD enables the development of capabilities and supplier performance, which is especially relevant ...
