Wine quality under integrated, organic and biodynamic management using image-forming methods and sensory analysis
(2021-12-24)
Background and aims
The image-forming methods copper chloride crystallization, capillary dynamolysis and circular chromatography are presented as an instrument for assessing wine quality. Wine quality of samples from a long-term field trial comparing integrated, organic and biodynamic management were investigated by using image-forming methods and sensory analysis.
Methods and results
Concerning the image-forming methods copper chloride crystallization, capillary dynamolysis and circular chromatography, the images ...

Optimization of Cooling Utility System with Continuous Self-Learning Performance Models
(2019-05-20)
Prerequisite for an efficient cooling energy system is the knowledge and optimal combination of different operating conditions of individual compression and free cooling chillers. The performance of cooling systems depends on their part-load performance and their condensing temperature, which are often not continuously measured. Recorded energy data remain unused, and manufacturers’ data differ from the real performance. For this purpose, manufacturer and real data are combined and continuously adapted to form part-load ...

Left preference for sport tasks does not necessarily indicate left-handedness
(2014)
In the elite domain of interactive sports, athletes who demonstrate a left preference (e.g., holding a weapon with the left hand in fencing or boxing in a ‘southpaw’ stance) seem overrepresented. Such excess indicates a performance advantage and was also interpreted as evidence in favour of frequency-dependent selection mechanisms to explain the maintenance of left-handedness in humans. To test for an overrepresentation, the incidence of athletes’ lateral preferences is typically compared with an expected ratio of ...

Revisiting climate change effects on winter chill in mountain oases of northern Oman
(2020-10-07)
For centuries, traditional high-altitude oases in Oman have depended on the cultivation of deciduous fruit trees. This study explores the effects of climate change on winter chill (estimated as Chilling Hours—CH and Chill Portions—CP), a prerequisite to overcoming dormancy and initiating flowering, in three Omani oases. The results are compared with findings from an earlier study which reported a decrease in the numbers of CH in high-elevation oases by an average of 1.2–9.5 CH year−1 between 1983 and 2008. Location-specific ...

A value-theoretic approach to economic dynamics and evolution—synthesizing different Marxian modules in a simulation model
(2020-05-08)
This part is devoted to simulation experiments based on the simulation model developed in part I from the value-theoretic reconstruction of the main parts of Marx’s critique of Political Economy. After introducing the main parameters and the range of their variation (Section 1), a singular run as well as a sensitivity analysis for the chosen standard configuration (‘moderation regime’) is presented in Section 2. This is accomplished by configurations depicting characteristics of the capitalist development emphasized ...

Performance Expectancies Moderate the Effectiveness of More or Less Generative Activities Over Time
(2019-08-21)
We examined if the benefits of generation for long-term learning depend on individual differences in performance expectancies (PEs) prior to learning. We predicted that a greater generative activity (problem-solving) compared to less generative activity (worked-examples) should be more effective for pupils with higher PEs, especially in the long run. As a comparison group for problem-solving, we implemented a special type of worked-examples that decreased engaging in self-explanations, because our main prediction ...

Die Gewährleistung von Krankheitshilfen bei asylsuchenden Menschen: Zweiklassenmedizin in Deutschland?
(2020-09-22)
Hintergrund
Es gibt im Bereich des Asylbewerberleistungsgesetzes (AsylbLG) zwei Möglichkeiten der Leistungsgewährung mit praktischer Relevanz für die Gesundheitsversorgung (abhängig von der Voraufenthaltszeit): die Grundleistungen und die Leistungen in besonderen Fällen analog zum Sozialgesetzbuch (SGB) XII.
Methodik
Die Sekundärdatenanalyse untersucht das Leistungsgeschehen im Krankheitsfall bei den Leistungsempfängern nach dem AsylbLG beim Forschungsdatenzentrum der Statistischen Ämter des Bundes und der Länder. ...

Cellular morphology of leg musculature in the water bear Hypsibius exemplaris (Tardigrada) unravels serial homologies
(2019-10-16)
Tardigrades (water bears) are microscopic, segmented ecdysozoans with four pairs of legs. Lobopodous limbs that are similar to those seen in tardigrades are hypothesized to represent the ancestral state of Panarthropoda (Tardigrada + Onychophora + Arthropoda), and their evolutionary history is important to our understanding of ecdysozoan evolution. Equally important is our understanding of the functional morphology of these legs, which requires knowledge of their musculature. Tardigrade musculature is well documented ...

New Leadership – Führen in agilen Unternehmen
(2021-12-16)
Das Prinzip der Agilität stellt Führungskräfte vor die Herausforderung, Führung neu zu denken und umzusetzen. Sie verlieren Positionsmacht und müssen sich auf Augenhöhe einlassen und ihre Macht teilen. Unsere Reflexionsfragen helfen Führungskräften, vom „Nowland“ zum „Nextland“ zu kommen. Wir zeigen auf, wie sie durch agile Führung Handlungsspielraum und Einfluss auf gesellschaftliche Entwicklungen gewinnen, und stellen das Konzept „Psychologische Sicherheit“ als hilfreiche Methode zur Selbststeuerung vor.

Rechte Radikalisierung und Deradikalisierung – Perspektiven in der psychologischen Beratung. Zum Film „Skin“ von Guy Nattiv
(2022-01-10)
Vor dem Hintergrund des Films „Skin“ von Guy Nattiv (2018) wird ein Einblick in die Dynamiken von Radikalisierungsprozessen gegeben unter Einbeziehung einer multifaktoriellen Perspektive. In einem zweiten Schwerpunkt werden die Gelingens- und Rahmenbedingungen von Deradikalisierungsprozessen erörtert. Der Beitrag schließt mit der Darstellung eines Beratungsansatzes zur Deradikalisierung.
