Nonstationarity in wildlife disease dynamics: insights from the prairie dog–plague system

Oikos, EarlyView.
Ecological relationships often vary in strength and direction across ecosystems, a pattern that has become increasingly evident as ecology expands to broader spatial and temporal scales. Although such nonstationarity – the changing effect of predictor variables across spatiotemporal contexts – is widely acknowledged in ecological research, it has ...

From Connections to Actions: When Do Government Ties Matter to Nonprofit Organizational Performance?

Public Administration and Development, EarlyView.
ABSTRACT Nonprofit organizations are essential for public service delivery, yet the value of their government ties is contested. This study examines the mechanism that translates these connections into tangible results. We propose that political networking—the deliberate cultivation and use of official relationships—is the critical catalyst.

Stair‐Climbing Wheelchairs for Enhanced Mobility: A Comprehensive Review of Fundamental Mechanisms, Design Concepts, and Performance Analysis

Journal of Field Robotics, EarlyView.
ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.

Sentipensar [Feel‐Thinking] Cultivates Collective Scientific Sensemaking and Worldbuilding Within and Beyond Ecological Despair

Science Education, EarlyView.
ABSTRACT Educating youth about environmental and climate justice is crucial in realizing a sustainable and flourishing future. Yet this can be challenging given the intense eco‐emotions youth experience and express while learning about these consequential realities and their implications.

Investor Heterogeneity, Sustainable Board Governance, and Corporate Social Responsibility Performance: Empirical Evidence From Europe

Sustainable Development, EarlyView.
ABSTRACT This study applies an agency‐theoretical lens to examine how investor heterogeneity, specifically institutional, foreign, and domestic ownership, influences corporate social responsibility (CSR) performance. Drawing on extensions of classical agency theory that account for heterogeneous shareholder preferences and principal‐principal conflicts,

Promoting Climate‐Friendly Behaviour Under Cognitive and Coordination Constraints: A Multi‐Level Framework for Sustainable Development Governance

Sustainable Development, EarlyView.
ABSTRACT Despite widespread concern about climate change, climate‐friendly behaviour remains difficult to sustain in practice. This article argues that the core challenge lies less in insufficient motivation than in the cognitive and coordination demands imposed by prevailing decision environments.
