Advanced Engineering Materials, EarlyView.Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Measuring Indirect Reciprocity: Whose Back Do We Scratch? [PDF]
This paper presents an experimental investigation of strong indirect reciprocity. We examine both generalized indirect reciprocity (if A helps B then B helps C) and social indirect reciprocity (if A helps B then C helps A), in a setting where reciprocal ...

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry
Advanced Functional Materials, EarlyView.In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

We define social reciprocity as the act of demonstrating one's disapproval, at some personal cost, for the violation of widely-held norms (e.g., don't free ride).

Reciprocity as a Key Concept for Social Media and Society
Social Media + Society, 2015 The concept of reciprocity, particularly in the pro-social sense of mutually beneficial exchange, presents an opportunity befitting the start of a new journal on social media. Namely, how might a concept of social exchange help us understand a mediascape

Advanced Functional Materials, EarlyView.We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Reputation or Reciprocity? An Experimental Investigation [PDF]
Recent evidence highlights the importance of social norms in many economic relations. However, many of these relationships are long-term and provide repeated game incentives for performance.

Acta Universitatis Sapientiae: European and Regional Studies, 2019 The main objective of the paper is to highlight the changes in the situation of the Hungarian minority in Romania and the Romanian minority in Hungary living in the divided Transylvania from the Second Vienna Arbitration from 30 August 1940 to the end of

Advanced Functional Materials, EarlyView.A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

Emotions Enforce Fairness Norms (a Simple Model of Strong Reciprocity) [PDF]
In experimental games, many subjects cooperate contrary to their material interest and they do that in a reciprocal manner. In addition, many subjects punish those others who behave unkindly, and previous history usually influences subjects’ choices.
