Indirect Reciprocity and Strategic Reputation Building in an Experimental Helping Game [PDF]

We study indirect reciprocity and strategic reputation building in an experimental helping game. At any time only half of the subjects can build a reputation.

Observational evidence that economic reciprocity pervades self-organized food co-operatives

Evolutionary Human Sciences
Evolutionary scientists argue that prosociality has been central to human ecological success. Theoretical models and behavioural experiments have found that prosociality, and cooperation in particular, is conditional and context dependent, that ...

Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters

Advanced Functional Materials, EarlyView.
An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation

Advanced Functional Materials, EarlyView.
Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

Same behavior, different perspectives: direct reciprocity differences between children with autism and children with typical development

BMC Psychiatry
Background Direct reciprocity is closely related to social behavior in children with Autism Spectrum Disorder (ASD) and is an important guarantee of their integration into society.

Proximity‐Tuned Magnetic and Transport Anomalies in All‐Epitaxial Fe5−xGeTe2/WSe2 Van der Waals Heterostructures

Advanced Functional Materials, EarlyView.
All‐epitaxial and scalable ferromagnetic/non‐magnetic Fe5−xGeTe2/WSe2 van der Waals (vdW) heterostructures exhibiting room‐temperature magnetism and perpendicular magnetic anisotropy (PMA) are realized. The system displays proximity‐tuned magnetic anisotropy, thickness‐dependent unconventional Hall effects, and temperature‐dependent sign reversal of ...

Reciprocity, Exchange and Redistribution. An experimental investigation inspired by Karl Polanyi’s The Economy as Instituted Process [PDF]

Inspired by Karl Polanyi’s writings on three allocation modes, namely reciprocity, exchange and redistribution, we first tested a reciprocity ring with ten players.

The reciprocity objective! The economic business environment and transnational corporations loyalty to the host country in Tanzania

Cogent Business & Management
Foreign companies, including transnational corporations (TNCs), have shown disloyalty toward their hosts in sub-Saharan Africa by, among other things, scaling back strategic expansion plans, closing operations, and shifting income-generating activities ...

Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films

Advanced Functional Materials, EarlyView.
We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect
