Bewegte Lebenswelten – Einblicke in Raum- und Bewegungserleben in Ganztagsschulen aus Sicht von Kindern
(2020-11-17)
Vor dem Hintergrund des flächendeckenden Ausbaus ganztägiger Bildungsangebote als einem der größten bildungspolitischen Reformprojekte in Deutschland und des Diskurses zur Institutionalisierung von Kindheit bestand das Ziel der diesem Beitrag zugrundeliegenden Studie darin, mit einem partizipativ ausgerichteten Mixed-Methods-Design die Perspektive der Kinder auf Ganztagsschule als ihren Lebensort zu beleuchten. Mit einer aneignungstheoretischen Perspektive auf das Erleben von Raum und Bewegung in vorwiegend informellen ...

Agil, hierarchiefrei und selbstorganisiert im New Work oder überwältigt von Systemstrukturen und unterdrückten gruppendynamischen Prozessen im New Office
(2020-11-03)
Dieser Beitrag in der Zeitschrift Gruppe. Interaktion. Organisation. (GIO) stellt eine explorative qualitative Studie zum Erleben von Sinn und Bindung durch Mitarbeitende in agilen New Work Umwelten vor, indem sie Wirkungen von Selbstorganisation, flachen Hierarchien, und elaborierten agilen Systemarchitekturen im Gegenlicht von persönlichen Beziehungen, gruppendynamischen Prozessen und Aspekten des psychologischen Empowerments betrachtet.

Mineralisation of distinct biogas digestate qualities directly after application to soil
(2020-11-02)
Biogas is an important energy source produced by the anaerobic fermentation of raw faecal slurries and plant residues. Separation of the total digestate increases the fertilizer quality of the liquid fraction and the carbon sequestration potential of the solid fraction. A 12-day incubation study was carried out to investigate the relationships between the chemical composition of different digestate qualities and the immediate response of soil microbial activity and biomass indices. The highest cumulative (Σ) CO2-C ...

Combined leaching and plant uptake simulations of PFOA and PFOS under field conditions
(2020-08-31)
Per- and polyfluoroalkyl substances (PFASs) are used in industrial production and manufacturing but were repeatedly detected in agricultural soils and therefore in cash crops in recent years. Dissipation of perfluoroalkyl acids (PFAAs), a sub-group of PFASs, in the environment was rather attributed to the formation of non-extractable residues (NER) than to degradation or transformation. Currently, there are no models describing the fate of PFAAs in the soil-plant continuum under field conditions, which hampers an ...

Are criminals better lie detectors? Investigating offenders' abilities in the context of deception detection
(2020-10-24)
The present research examined lie detection abilities of a rarely investigated group, namely offenders. Results of the studies conducted thus far indicated a better performance of offenders compared to non‐offenders when discriminating between true and false messages. With two new studies, we aimed at replicating offenders' superior abilities in the context of deception detection. Results of Study 1 (N = 76 males), in contrast, revealed that offenders were significantly worse at accurately classifying true and false ...

Chalcogen‐Transfer Rearrangement: Exploring Inter‐ versus Intramolecular P−P Bond Activation
(2020-07-17)
tert‐Butyl‐substituted diphospha[2]ferrocenophane has been used as a stereochemically confined diphosphane to explore the addition of O, S, Se and Te. Although the diphosphanylchalcogane has been obtained for tellurium, all other chalcogens give diphosphane monochalcogenides. The latter transform via chalcogen‐transfer rearrangement to the corresponding diphosphanylchalcoganes upon heating. The kinetics of this rearrangement has been followed with NMR spectroscopy supported by DFT calculations. Intermediates during ...

Spontaneous inferential processing while reading interleaved expository texts enables learners to discover the underlying regularities
(2020-11-05)
Recent studies on text sequencing found learning advantages of interleaving over blocking in terms of high‐level inferences. We conducted a 2 × 2 × 2 mixed factorial experiment with college students (n = 117) by manipulating text sequence (interleaved vs. blocked) and self‐questioning activity while reading (spontaneous vs. prompted) between subjects and testing delay (immediately vs. 1‐week delay) within subjects. Results revealed that students are spontaneously engaged in self‐questioning and inferential processing ...

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. ...

Influence of pre-drying storage time on essential oil components in dried hops (Humulus lupulus L.)
(2020-10-15)
BACKGROUND
It is well known that duration of pre-drying storage impacts on hop quality. However, little knowledge exists regarding its actual effects on valuable hop components. To investigate these effects, fresh hop cones were stored for 5 or 24 h and dried for 210 min at 65 °C thereafter. Furthermore, to understand the effect of freezing hop cones on the essential oil content, both fresh and stored samples were frozen before and after drying.
RESULTS
The results from gas chromatography analysis show an increase ...

Long‐term vegetation changes in Nardus grasslands indicate eutrophication, recovery from acidification, and management change as the main drivers
(2020-07-08)
Questions
Which trends and patterns of community change occurred in Nardus grasslands over recent decades in parts of the Continental biogeographic region of Germany? Are patterns and trends consistent across two study regions? Do impacts of environmental changes on Nardus grasslands in Central Europe correspond to those identified in the European Atlantic biogeographic region?
Location
East Hesse Highlands, Germany.
Methods
In 2012–2015, we re‐surveyed quasi‐permanent plots that had been initially surveyed ...
