Was passiert im Gründercoaching?
(2020-04-16)
Die vorliegende Studie exploriert die Rolle von Prozess- und Expertenberatung im Gründercoaching. Die Ergebnisse einer qualitativen Interviewstudie mit 44 Coaches zeigen, dass beide Modelle im Gründercoaching von Bedeutung sind, wobei deren Gewichtung sehr unterschiedlich ausfallen kann. Innerhalb des Prozessberatungsanteils gehen Coaches auf 17 verschiedene Themen ein, im Expertenberatungsanteil sind vier Themenbereiche relevant. Coaches setzen das jeweilige Beratungsmodell bewusst im Coachingprozess ein und reagieren ...

Mode properties of telecom wavelength InP-based high-(Q/V) L4/3 photonic crystal cavities
(2020-05-13)
We present finite-difference time domain simulations and optical characterizations via micro-photoluminescence measurements of InP-based L4/3 photonic crystal cavities with embedded quantum dots (QDs) and designed for the M1 ground mode to be emitting at telecom C-band wavelengths. The simulated M1 Q-factor values exceed 106, while the M1 mode volume is found to be 0.33 × (λ/n)3, which is less than half the value of the M1 mode volume of a comparable L3 cavity. Low-temperature micro-photoluminescence measurements ...

A modification of a traditional Ethiopian maize store for solar powered ambient drying to reduce post-harvest losses
(2020-07-14)
A gombisa is a traditional Ethiopian structure widely used for maize storage over several months. It lacks adequate ventilation for timely moisture removal, which promotes mold development and aflatoxin production. In this study, a traditional gombisa was compared to one modified by installing a solar powered fan to provide forced ambient air ventilation during daytime. Approximately 900 kg of moist ear maize were loaded into each structure and samples from selected locations were weighed periodically to monitor ...

Mismatch of Glucose Allocation between Different Life Functions in the Transition Period of Dairy Cows
(2020-06-13)
Simple Summary
The reasons for the development of diseases in the transition period of dairy cows are manifold and highly farm- and cow-specific. Nevertheless, links exist between the degree of negative energy balance (NEB) and disease susceptibility, which suggest a mutual adverse relationship between immune and productive functions. Glucose is the most essential fuel and precursor for both immune cells and mammary epithelial cells (MEC). While the delivery of glucose by the intermediary metabolism is not always ...

The Potential Influence of Organic Food Consumption and Intention-Behavior Gap on Consumers’ Subjective Wellbeing
(2020-05-18)
This paper applied a self-administered survey to investigate the impact of organic food behavior and the intention-behavior gap in organic food consumption (OIBG) on consumers’ subjective wellbeing including physical, emotional, social and intellectual dimensions. The survey was carried out with 385 consumers. Furthermore, the study conducted a food test to explore the different impacts of organic and conventional food samples on the mental and physical conditions of consumers’ wellbeing applying a psychological ...

Auswirkungen verschachtelten Lernens auf das prozedurale und konzeptuelle Wissen von Lernenden über Zuordnungen
(2020-04-06)
Häufig werden im Mathematikunterricht Lerninhalte eher separiert behandelt. Der Ansatz des sogenannten verschachtelten Lernens geht dagegen davon aus, dass es in vielen Fällen sinnvoll ist, die Lerninhalte abwechselnd und vermischt anzuordnen, um bei den Schülerinnen und Schülern lern- und verstehensförderliche Prozesse anzuregen sowie nachhaltiges Lernen zu fördern. Verschachteltes Lernen zählt zu den wünschenswerten Erschwernissen. Das Ziel der wünschenswerten Erschwernisse ist, durch eine Erhöhung des kognitiven ...

Instability Resistance Training improves Working Memory, Processing Speed and Response Inhibition in Healthy Older Adults: A Double-Blinded Randomised Controlled Trial
(2020-02-13)
Aging is associated with declines in physical and cognitive performance. While there is no doubt about beneficial effects of physical exercise on proxies of strength and balance, the overall evidence for positive effects of resistance and balance training on executive functions is rather inconsistent. Whether the simultaneous exercising of strength and balance, i.e., instability resistance training, promotes executive functions in older adults is unknown. In the present trial, we tested the effects of unstable vs. ...

How Do Gaining and Losing Streams React to the Combined Effects of Climate Change and Pumping in the Gharehsoo River Basin, Iran?
(2020-03-18)
Projections of potential impacts of climate change and groundwater abstraction on gaining and losing streams, particularly in ephemeral river basins exhibiting sporadic and intricate flux exchanges, have remained largely unexplored. To fill this gap, we propose a promising modeling scheme based on the new fully integrated hydrological model SWAT‐MODFLOW‐NWT, calibrated and validated for 1978–2012, to quantify the intertwined surface‐groundwater interactions under a conjuncture of three climatic emission scenarios ...

Willingness-to-Pay for District Heating from Renewables of Private Households in Germany
(2020-05-18)
Recent discussion about future energy production promotes the recovery of industrial heat as a potential solution to reduce carbon emissions. Experts call for an expansion of central heating by renewable energy systems to ensure a decarbonization of energy systems. In this context, district heating could play a significant role in city and district planning. Nonetheless, for private households, environmental aspects are only one factor amongst others as, e.g., capital costs, comfort and security. In this study, we ...

Using CFD Modelling to Relate Pig Lying Locations to Environmental Variability in Finishing Pens
(2020-03-03)
The purpose of this research was to determine which environmental factors within the pen space differ between the locations where pigs choose to lie and areas they avoid. Data on external weather engconditions and the construction parameters for an existing commercial finishing pig building were input into a Dynamic Thermal (DT) model generating heat flow and surface temperature patterns in the structure and these were then input into a Computational Fluid Dynamics (CFD) model to generate data on the theoretical ...
