Risky Punishment and Reward in the Prisoner’s Dilemma [PDF]

We conduct a prisoner’s dilemma experiment with a punishment/reward stage, where punishments and rewards are risky. This is compared with a risk free treatment.

Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions

Advanced Functional Materials, EarlyView.
Magnetic force microscopy operated under vacuum conditions enables the qualitative identification of higher‐order skyrmions and antiskyrmions in Co/Ni multilayers at room temperature. Distinct stray‐field contrast signatures arise from vertical Bloch lines and complex domain‐wall configurations.

Initial construct stability of long cephalomedullary nails with superior locking for a complex trochanteric fracture model AO31A2.2– a biomechanical study

Journal of Orthopaedic Surgery and Research
Background Complex fractures of the trochanteric region, as well as fractures located in the directly subtrochanteric region, are controversially discussed around the world regarding the nail type to be used.

Macroeconomic Evolution after a Production Shock: the Role for Financial Intermediation [PDF]

Financial intermediaries may increase economic efficiency through intertemporal risk smoothing. However without an adequate regulation, intermediation may fail to do this.

A New Threshold Switching Device With Tunable Negative Differential Resistance Based on ErMnO3 Polymorphs

Advanced Functional Materials, EarlyView.
Polymorph engineering in ErMnO3 enables low‐voltage, forming‐free threshold switching with tunable negative differential resistance. Conducting orthorhombic regions embedded in an insulating hexagonal matrix provide controlled Joule‐heating‐enhanced Poole–Frenkel transport. The hexagonal phase prevents excessive heating and breakdown.

Forschung in der Lehrerbildung

Beiträge zur Lehrerinnen- und Lehrerbildung, 1998
Die Lehrerbildung hat bislang kaum eigene Forschung betrieben und auch kaum Forschung nötig gehabt. Die Tertialisierung der Ausbildung legt einen Forschungsbezug nahe, er macht wesentlich die Unterscheidung zur bisherigen Ausbildung aus. "Forschung" ist

Herding with and without Payoff Externalities - An Internet Experiment [PDF]

Most real world situations that are susceptible to herding are also characterized by direct payoff externalities. Yet, the bulk of the theoretical and experimental literature on herding has focused on pure informational externalities.

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
