Kinder als „Stakeholder“ in Kindertageseinrichtungen [KiSte] – Studie zu den Sichtweisen der Kinder auf institutionelle Arrangements
(2020-04-21)
Das Forschungsprojekt Kinder als „Stakeholder“ in Kindertageseinrichtungen (KiSte) zielt auf die empirisch fundierte Erfassung der unterschiedlichen Sichtweisen von Kindern auf ihre Kindertageseinrichtung (Kita). Es wird davon ausgegangen, dass Kinder ihre eigenständigen Ideen zur Ausgestaltung der frühpädagogischen Arrangements haben, diese aber nicht durchgängig im Diskurs um die Weiterentwicklung frühpädagogischer Arrangements wahrgenommen werden. Da Kinder neben den Pädagog*innen die zentralen Akteur*innen und ...

Entrepreneurial Coaching: A Two‐Dimensional Framework in Context
(2020-05-08)
Coaching is increasingly used to support entrepreneurs across different stages of the entrepreneurial process. Due to its custom‐tailored, active, and reflection‐oriented approach, it has been suggested that it is particularly well suited to entrepreneurs’ complex job demands. However, in the entrepreneurial context, the term coaching lacks a clear definition and is frequently used interchangeably with other types of support. We therefore sought to characterize entrepreneurial coaching (EC) and to position it relative ...

How does self-employment affect pension income? A comparative analysis of European welfare states
(2020-12-03)
The characteristics of self-employment in Europe have changed profoundly in the last decades. The share of solo self-employment has grown and individuals combine more frequently dependent employment with self-employment at the same time, or more often switch between dependent employment and self-employment. These developments heavily affect the pensions of the self-employed and therefore present a challenge for the old-age security systems of European welfare states. So far, there has been little comparative research ...

Phospholipids containing ether-bound hydrocarbon-chains are essential for efficient phagocytosis and neutral lipids of the ester-type perturb development in Dictyostelium
(2020-07-16)
Lipids are the building blocks for cellular membranes; they provide signalling molecules for membrane dynamics and serve as energy stores. One path of their synthesis is initiated by glycerol-3-phosphate acyltransferase (GPAT), which in Dictyostelium resides on the endoplasmic reticulum. When an excess of fatty acids is present, it redistributes to storage organelles, the lipid droplets. Mutants, where the GPAT was eliminated by homologous recombination, produce fewer lipid droplets and are almost devoid of ...

Organization of the central nervous system and innervation of cephalic sensory structures in the water bear Echiniscus testudo (Tardigrada: Heterotardigrada) revisited
(2021-06-15)
The tardigrade brain has been the topic of several neuroanatomical studies, as it is key to understanding the evolution of the central nervous systems in Panarthropoda (Tardigrada + Onychophora + Arthropoda). The gross morphology of the brain seems to be well conserved across tardigrades despite often disparate morphologies of their heads and cephalic sensory structures. As such, the general shape of the brain and its major connections to the rest of the central nervous system have been mapped out already by early ...

Effects of morphology in controlling propagation of density currents in a reservoir using uncalibrated three-dimensional hydrodynamic modeling
(2020-04-29)
In this study, effects of basin morphology are shown to affect density current hydrodynamics of a large reservoir using a three-dimensional (3D) hydrodynamic model that is validated (but not calibrated) with in situ observational data. The AEM3D hydrodynamic model was applied for 5-month simulations during winter and spring flooding for the Maroon reservoir in southwest Iran, where available observations indicated that large-scale density currents had previously occurred. The model results were validated with near-bottom ...

Transcriptomic, peptidomic, and mass spectrometry imaging analysis of the brain in the ant Cataglyphis nodus
(2021-03-11)
Behavioral flexibility is an important cornerstone for the ecological success of animals. Social Cataglyphis nodus ants with their age-related polyethism characterized by age-related behavioral phenotypes represent a prime example for behavioral flexibility. We propose neuropeptides as powerful candidates for the flexible modulation of age-related behavioral transitions in individual ants. As the neuropeptidome of C. nodus was unknown, we collected a comprehensive peptidomic data set obtained by transcriptome analysis ...

Comeback als demokratische Führungsmacht?
(2021-07-08)
Joe Biden stellt die US-Außenpolitik unter ein demokratisches Paradigma, will demokratische Allianzen festigen und hat einen „Gipfel für die Demokratie“ versprochen. Ziel ist es, das Gewicht freiheitlicher Staaten im Systemkonflikt mit Autokratien zu erhöhen. Bündnispartner in Europa und Asien reagieren skeptisch, fürchten eine Verhärtung der Konflikte mit China und Russland und den Verlust der Handlungsfreiheit. Wir plädieren für eine Allianz der Demokratien, mit Blick auf die Resilienz ihrer politischen Systeme und ...

Betriebliche Mobilitätsmanagementmaßnahmen – ein Anstoß für Veränderungen in Mobilitätsverhalten und -einstellungen Mitarbeitender?
(2021-06-09)
Betriebliches Mobilitätsmanagement (BMM) fokussiert auf die Verkehrsgestaltung hinsichtlich Pendel- und Berufsverkehr, Dienstreisen und Kundenverkehr. Ziel ist es, beispielsweise Parkplatzauslastungen zu verringern oder Verhaltensänderungen bei den Mitarbeitenden hinsichtlich der Verkehrsmittelwahl hervorzurufen. Bisher ist BMM in Deutschland wenig implementiert und in geringem Umfang erforscht.
Vor diesem Hintergrund stellt dieser Artikel das Instrument BMM theoretisch dar und präsentiert ein zugehöriges ...
