Cooperation in social dilemmas is essential for the functioning of systems at multiple levels of complexity, from the simplest biological organisms to the most sophisticated human societies. Cooperation, although widespread, is fundamentally challenging to explain evolutionarily, since natural selection typically favors selfish behavior which is not socially optimal. Here we study the evolution of cooperation in three exemplars of key social dilemmas, representing the prisoner's dilemma, hawk-dove and coordination classes of games, in structured populations defined by complex networks. Using individual-based simulations of the games on model and empirical networks, we give a detailed comparative study of the effects of the structural properties of a network, such as its average degree, variance in degree distribution, clustering coefficient, and assortativity coefficient, on the promotion of cooperative behavior in all three classes of games.

This paper critically examines the scientific and ethical underpinnings of gender-affirming care, particularly for minors. While major medical organizations endorse such interventions as medically necessary, the evidence supporting their long-term safety and efficacy remains limited. Research into hormonal, neuroanatomic, and genetic influences reveals a strong biological basis for gender identity, challenging social constructionist arguments.

Background: Taiwan implemented global hospital budgeting with a floating-point value, which created a prisoner's dilemma. As a result, hospitals increased service volume, which caused the floating-point value to drop to less than one New Taiwan Dollar (NTD). The recent increase in the number of hospital beds and the call to enhance the floating-point value to one NTD raise concerns about the potential for increased financial burden without adding value to patient care if hospitals expand their bed capacity for volume-based competition.

Prenatal screening (PNS) for Sickle Cell Disease (SCD) offers a potential avenue for informed reproductive choices and the sickle elimination initiative of the Government of India. The objective of the study was to explore perceptions and ethical dilemmas surrounding prenatal screening for sickle cell disease and subsequent termination of pregnancy among pregnant women and key stakeholders from the tribal region of Gujarat. The study employed sequential mixed-methods research, embedding a participatory research approach.
