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. ...

Distributed Practice: Rarely Realized in Self-Regulated Mathematical Learning
(2018-11-20)
The purpose of the present study was to investigate the effect and use of distributed practice in the context of self-regulated mathematical learning in high school. With distributed practice, a fixed learning duration is spread over several sessions, whereas with massed practice, the same time is spent learning in one session. Distributed practice has been proven to be an effective tool for improving long-term retention of verbal material and simple procedural knowledge in mathematics, at least when the practice ...

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, ...

Effect of Sieve Particle Size and Blend Proportion on the Quality Properties of Peeled and Unpeeled Orange Fleshed Sweet Potato Composite Flours
(2020-06-04)
Orange fleshed sweet potato (OFSP) has great potentials to improve the nutritional benefits of bakery products when processed into quality flour. This study investigated the effects of sieve particle sizes (250 μm and 500 μm) and flour blend proportions on the physicochemical, nutritional, functional and pasting properties of peeled and unpeeled OFSP composite flours. Peeled OFSP composite flours had significantly (p < 0.05) higher crude protein (CP), lightness (L*), oil absorption capacity (OAC) and water solubility ...

On the Impact of Texture and Grain Size on the Pseudoelastic Properties of Polycrystalline Fe–Ni–Co–Al–Ti Alloy
(2020-05-08)
The effects of thermomechanical treatments on crystallographic texture and grain size evolution and their impact on the pseudoelastic properties in Fe41–Ni28–Co17–Al11.5–Ti2.5 (at.%) were studied in the present paper. The results show that cold rolling leads to brass-type texture in this alloy, which is typical for low stacking fault energy materials. Thermal treatments up to 1300 °C were conducted and it is shown that the presence of β-phase helps to control grain growth. After the dissolution of the secondary phase ...
