Coaching zum Spannungsfeld von Dominanz und Unterordnung – Perspektiven für eine situationsadäquate Selbstregulation
(2021-10-27)
Die Forschung widmete sich der Frage, wie Einzelcoaching dazu beiträgt, dass Coachees eine situationsadäquate Selbstregulation von Dominanz und Unterordnung gelingt. Zunächst wird die Relevanz des Themas für die Coachingpraxis und das Spannungsfeld von Dominanz und Unterordnung erörtert. Das Instrument der operationalisierten psychodynamischen Diagnostik diente als Grundlage für das Forschungsdesign. Anschließend wird die verwendete Methode beschrieben, und die Ergebnisse der Forschung werden komprimiert dargelegt. ...

On the Automation of Flood Event Separation From Continuous Time Series
(2020-07-28)
Can machine learning effectively lower the effort necessary to extract important information from raw data for hydrological research questions? On the example of a typical water-management task, the extraction of direct runoff flood events from continuous hydrographs, we demonstrate how machine learning can be used to automate the application of expert knowledge to big data sets and extract the relevant information. In particular, we tested seven different algorithms to detect event beginning and end solely from a ...

Influence of hot deformation on the precipitation hardening of high-strength aluminum AA7075 during thermo-mechanical processing
(2021-04-21)
The aim of this work was to investigate the effect of hot deformation on the aging behavior of precipitation-hardenable aluminum alloy AA7075 within a novel thermo-mechanical forming process, in order to gain insight into its precipitation kinetics. For this purpose, the material was formed at 420 °C after undergoing solution treatment to different strain levels ranging from 2% to 10% to obtain different dislocation densities. After undergoing hot deformation, aging at 120 °C with different parameters was carried out ...

Der innerpsychische Konflikt Individuation vs. Abhängigkeit im Coaching: Zentrale Ergebnisse einer qualitativen Studie zur Praxis erfahrener Coaches
(2021-11-09)
Die unbewusste Dynamik von innerpsychischen Konflikten ist ein wichtiger Inhalt des Erlebens und Verhaltens von Menschen und hat vermutlich einen Einfluss in Coachingprozessen. Diese Studie fokussiert den Grundkonflikt „Individuation vs. Abhängigkeit“ in Einzelcoachings. In einer kleinen qualitativen Feldstudie (n = 13) wurden erfahrene Coaching-Expert/innen zu subjektiven Theorien und präferierten Arbeitskonzepten im Handling dieses Konflikts im Einzelcoaching befragt. Die Inhaltsanalyse zeigt Strategien zum Handling ...

Liquid Silicone Rubber Foams Made with Water as Blowing Agent
(2021-08-18)
Liquid silicone rubber (LSR) is primarily used in injection molding. Foamed molded parts made of LSR are almost nonexistent because the process reliability of LSR foam injection molding is currently not given. It makes sense to have suitable foaming processes for this material as well, because the density of this elastomer is about 1.15 g cm−3. With the injection molding process presented herein for foaming LSR, density reductions of up to 40% can be achieved. In this process, up to 3% by weight of water is added to ...

Experimentelle Untersuchung zur Mehrphasenströmung in öleingespritzten Mehrphasenschraubenspindelpumpen
(2020-02-18)
Für die Förderung von Gemischen mit hohen Gasanteilen erfolgt die Entwicklung eines neuen Kühlkonzepts, indem das Prozessfluid in flüssiger Phase extern in die Förderkammer einer Mehrphasenpumpe eingespritzt wird. Neben der Regulierung des Thermomanagements trägt dies zur Spaltabdichtung bei, so dass der effektiv geförderte Volumenstrom steigt. Zur Untersuchung der Thermo‐ und Fluiddynamik einer solchen Mehrphasenpumpe wird ein transparentes Förderkammermodell der Pumpe mit externer Fluideinspritzung entwickelt. Das ...

On the Finite Orthogonality of q-Pseudo-Jacobi Polynomials
(2020-08-08)
Using the Sturm–Liouville theory in q-difference spaces, we prove the finite orthogonality of q-Pseudo Jacobi polynomials. Their norm square values are then explicitly computed by means of the Favard theorem.

The Covid-19 containment effects of public health measures: A spatial difference-in-differences approach
(2021-04-12)
The paper studies the containment effects of public health measures to curb the spread of Covid-19 during the first wave of the pandemic in spring 2020 in Germany. To identify the effects of six compound sets of public health measures, we employ a spatial difference-in-differences approach. We find that contact restrictions, mandatory wearing of face masks and closure of schools substantially contributed to flattening the infection curve. The significance of the impact of restaurant closure does not prove to be robust. ...

Micromagnetic Simulations of Submicron Vortex Structures for the Detection of Superparamagnetic Labels
(2020-10-15)
We present a numerical investigation on the detection of superparamagnetic labels using a giant magnetoresistance (GMR) vortex structure. For this purpose, the Landau–Lifshitz–Gilbert equation was solved numerically applying an external z-field for the activation of the superparamagnetic label. Initially, the free layer’s magnetization change due to the stray field of the label is simulated. The electric response of the GMR sensor is calculated by applying a self-consistent spin-diffusion model to the precomputed ...

When does a social norm catch the worm? Disentangling social normative influences on sustainable consumption behaviour
(2020-11-08)
Sustainable consumption obtains ever-increasing importance due to pressing social, environmental and economic issues. Extensive research has proposed the use of social norm communication as an effective means to encourage various kinds of pro-environmental behaviour, as well as sustainable consumption. However, although crucial to the development of effective social norm campaigns, tangible evidence for specific processes and conditions through which social norms foster sustainable consumption remains scarce. Thus, ...
