Selbstselektion beim Bezug des Betreuungsgeldes? Eine Analyse bezahlter und unbezahlter Arbeit von Müttern
(2020-04-04)
Zusammenfassung Das 2013 eingeführte und bereits zwei Jahre später wieder abgeschaffte bundesweite Betreuungsgeld gehörte zu den kontroversesten Themen der jüngeren deutschen Familienpolitik. Von Seiten politischer Akteure, die das Betreuungsgeld ablehnten, aber auch aus der Forschung wurde die Befürchtung geäußert, dass sich die Leistung negativ auf die Erwerbsbeteiligung von Müttern auswirke und eine traditionelle Aufteilung von bezahlter und unbezahlter Arbeit zwischen Müttern und Vätern befördere. Tatsächlich ...

Entwicklung einer psychoanalytisch begründeten Typologie von psychotischen Erkrankungen
(2020-04-28)
Der Artikel begründet die Notwendigkeit eines genuin psychoanalytischen und gleichsam in der empirischen Psychotherapieforschung anschlussfähigen Beitrags zum Verständnis psychotischer Erkrankungen. Die sequenziell erklärende Mixed-Methods-Studie „Therapie und Psychodynamik von Patient*innen mit psychotischen Symptomen“ (T3PS-Studie) fokussiert auf die Binnendifferenzierung psychotischer Erkrankungen. Hierfür soll eine psychoanalytisch begründete Typologie dieser Patient*innen anhand messender und hermeneutischer ...

Arthropod Communities in Urban Agricultural Production Systems under Different Irrigation Sources in the Northern Region of Ghana
(2020-08-01)
Urban and peri-urban agricultural (UPA) production systems in West African countries do not only mitigate food and financial insecurity, they may also foster biodiversity of arthropods and partly compensate for structural losses of natural environments. However, management practices in UPA systems like irrigation may also contribute to disturbances in arthropod ecology. To fill knowledge gaps in the relationships between UPA management and arthropod populations, we compared arthropods species across different irrigation ...

First-Order Shape Derivative of the Energy for Elastic Plates with Rigid Inclusions and Interfacial Cracks
(2020-11-16)
Within the framework of Kirchhoff–Love plate theory, we analyze a variational model for elastic plates with rigid inclusions and interfacial cracks. The main feature of the model is a fully coupled nonpenetration condition that involves both the normal component of the longitudinal displacements and the normal derivative of the transverse deflection of the crack faces. Without making any artificial assumptions on the crack geometry and shape variation, we prove that the first-order shape derivative of the potential ...

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 ...

Tests and academic cheating: do learning tasks influence cheating by way of negative evaluations?
(2020-04-27)
Desirable difficulties like tests were often shown to increase long-term learning. However, due to the complexity and difficulty of such tasks, they are also argued to result in negative consequences like stress, anxiety, pressure, frustration, or negative evaluations. In other studies, such consequences were, in turn, often found to increase dishonest behaviour. Hence, the present work tests the assumptions that tests as difficult learning tasks, contrary to reading, lead to more negative evaluations of the learning ...

A Stable N-Heterocyclic Silylene with a 1,1′-Ferrocenediyl Backbone
(2020-10-15)
The N-heterocyclic silylene [{Fe(η⁵-C₅H4-NDipp)₂}Si] (1DippSi, Dipp=2,6-diisopropylphenyl) shows an excellent combination of pronounced thermal stability and high reactivity towards small molecules. It reacts readily with CO₂ and N₂O, respectively affording (1DippSiO₂)₂C and (1DippSiO)₂ as follow-up products of the silanone 1DippSiO. Its reactions with H₂O, NH₃, and FcPH₂ (Fc=ferrocenyl) furnish the respective oxidative addition products 1DippSi(H)X (X=OH, NH₂, PHFc). Its reaction with H₃BNH₃ unexpectedly results in ...

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.

Changes in Dairy Products Value Chain in Georgia
(2020-07-22)
The livestock sector, as a part of the traditional food system in Georgia, occupies a considerable portion of the national economy. Though smallholder farmers are the key suppliers at the primary stage in the food value chain, the empowerment of smallholder farmers in the dairy production system in Georgia is a questionable matter. This research study reports the results of changes in the dairy sector in Georgia (Caucasus) after becoming independent from the Soviet Union (literature survey) and how these changes are ...

Articulating Body, Territory, and the Defence of Life: The Politics of Strategic Equivalencing between Women in Anti‐Mining Movements and the Feminist Movement in Peru
(2020-09-16)
In Latin America, rural and indigenous women have mobilised in defence of their territories and built strategic alliances with urban and mestiza feminist movements. This paper focuses on how these processes have played out in Peru, tracing the development of the discourse on ‘body as territory’, which articulates sexual and reproductive rights with territorial autonomy. It discusses the ‘cosmopolitics’ of translating the distinct concerns and worldviews of the women involved, arguing that this discourse has enabled ...
