Effects of Punitive Measures on Free Riding and Collective Immunity Under Q-Learning–Driven Epidemic Dynamics
Free-riding behavior poses a critical challenge to achieving collective immunity in vaccination campaigns, particularly when individuals make decisions based on short-term self-interest. This study investigates how punitive interventions can mitigate free-riding and enhance vaccination uptake under…

Greenwashing Versus Genuine Green: An Evolutionary Game of Corporate Strategy, Investor Trust, and ESG Regulation
The rapid growth of environmental, social, and governance (ESG) investment has not only accelerated corporate sustainability transitions but has also contributed to the prevalence of greenwashing. In such instances, firms disseminate misleading information to align with market preferences, thereby…

Relative Chaoticity of Natural Languages
This paper presents a novel approach to analyzing and grouping natural languages based on the degree of their chaoticity. It clusters 52 languages from 18 language families, according to the value of the entropy–complexity pair, to reveal the chaotic properties of semantic trajectories. The…

The Dual Interaction Structure of “Information-Group” in the Diffusion of Emergency Information: An Empirical Study From China
Monitoring, governing, and guiding public opinion on social media during emergencies is challenging, often leading to mass panic, rumors, and public opinion crises. Understanding the scale evolution of information and subjects within the public opinion ecology of emergencies can aid in achieving…

The Stability–Asymmetry Paradox in International Trade: A Fuzzy Logic Categorization of Partnerships
The 21st century has witnessed political upheavals, economic shocks, and inflation, all of which have disrupted global trade. In response, nations are increasingly aligning with blocs such as the SCO, BRICS, INSTC, and IMEEC to strengthen their resilience. This study asks How can countries identify…

A Unified Framework Linking Entropy, Fractal Dimension, and Lyapunov Exponents in Chaotic Dynamics
This study presents a universal operator framework predicting critical transitions in nonlinear systems through the intrinsic nexus of entropy, fractal geometry, and chaos. We derive a unified model (Equation 4) that integrates fractal dimension (Dᵓ), Lyapunov exponents (λᵢ), and entropy (S) into a…

Cybernetics in the Anthropocene’s Wake: Reframing Global Transformations Through the Emergent Human–Earth System
The Anthropocene has been a powerful conceptual lens for exploring the coupling of humans and the Earth system. While fostering a rich transdisciplinary discourse, its grounding in bounded geological time and emphasis on disruption has often reinforced the nature–culture divide and tended toward a…

Designing Optimal Intervention Policies for Bacterial CNS Infection Dynamics With Encephalitic Progression: A Multicontrol Compartmental Model
Central nervous system infections resulting from invasive bacterial pathogens are associated with a significant neurological burden. The ability of organisms such as Neisseria meningitidis and Streptococcus pneumoniae to invade the blood–brain barrier is often associated with severe neurological…
