The Biased Interaction Game: A System Theoretic Approach to the Emergence of Inequality, Hierarchy, and the Implications for the Likelihood of Cooperation

Systems Research and Behavioral Science, EarlyView.
ABSTRACT The emergence of cooperation in natural selection has been successfully studied using game theory and, despite the underlying selfish nature of the evolutionary process, a spectrum of plausible mechanisms have been proposed to determine the conditions under which cooperative behaviour is likely to occur.

A Methodological Framework to Study Change in Team Cognition Under the Dynamical Hypothesis

Topics in Cognitive Science, EarlyView., 2023
Abstract The dynamical hypothesis claims that cognitive systems, such as teams, are dynamical systems (i.e., an interdependent collection of individuals and their technology that change together over time). Following this hypothesis, team researchers have adopted dynamical approaches to better understand the team cognitive processes and states that ...

Cosmography with the Double-source-plane Strong Gravitational Lens AGEL150745+052256

The Astrophysical Journal
Strong gravitational lenses with two background sources at widely separated redshifts are a promising independent probe of cosmological parameters. We can use these systems, known as double-source-plane lenses (DSPLs), to measure the ratio ( β ) of ...

Experimental Investigations on the Impact of Operational Conditions on Bubble Dynamics and the Resulting Vibrations in Gas‐Stirred Ladles

steel research international, EarlyView.
This study applies sensitive vibration sensors to investigate gas bubble behavior in liquid metal during argon injection. Analysis of vibration signals provides insights into bubble evolution and the influence of gas flow and surface pressure. The results provide a basis for improved vibration‐based two‐phase flow models, enhancing accuracy in ...

Probing massive gravitons in f(R) with lensed gravitational waves

Physics Letters B
We investigate the novel features of gravitational wave solutions in f(R) gravity under proper gauge considerations in the shifted Ricci scalar background curvature (R1+ϵ).

The Evolution of Gravitational Lens Galaxies

, 1999
Most gravitational lens galaxies are early-type galaxies in relatively low density environments. We show that they lie on the same fundamental plane as early-type galaxies in both local and distant rich clusters. Their surface brightness evolution requires a typical star formation epoch of z=2-3, almost indistinguishable from that of rich cluster ...

State of the Field: The History of Masculinities

History, EarlyView.
Abstract This State of the Field article discusses how, when and why the history of masculinities has emerged since the 1980s, and why it continues to be an important research field today. The article begins with the field's multiple origin stories and then discusses its expansion in chronology, geography and theme, as well as newer directions for ...
