Abstract In this paper we apply Conley index theory in a covering space of an invariant set S , possibly not isolated, in order to describe the dynamics in S . More specifically, we consider the action of the covering translation group in order to define a topological separation of S which distinguishes the connections between the Morse sets within a Morse decomposition of S . The theory developed herein generalizes the classical connection matrix theory, since one obtains enriched information on the connection maps for non-isolated invariant sets, as well as for isolated invariant sets. Moreover, in the case of an infinite cyclic covering induced by a circle-valued Morse function, one proves that the Novikov differential of f is a particular case of the p -connection matrix defined herein.

Mental models and enduring climate action: the Earth Connection Film Festival
Climate change is one of the major interconnected social crises related to human health and the environment we face today, and motivating public action is a pressing challenge within that. The 2024 Earth Connection Film Festival screened 24 international films covering climate change through the lens of hope, connection, and responsibility. As part of a broader National Science Foundation research project to overcome climate apathy and build enduring environmental action, the festival provides films for a study on mental models and supports filmmakers covering climate change. This field report shares how the program was scientifically justified, the development of the festival, the event and its outcome, as well as takeaways for those interested in using film and media narratives as a vehicle for understanding and supporting social and behavioral change.

Background. We describe and provide an initial evaluation of the Climate Action Simulation, a simulation-based role-playing game that enables participants to learn for themselves about the response of the climate-energy system to potential policies and actions. Participants gain an understanding of the scale and urgency of climate action, the impact of different policies and actions, and the dynamics and interactions of different policy choices. Intervention. The Climate Action Simulation combines an interactive computer model, En-ROADS, with a role-play in which participants make decisions about energy and climate policy. They learn about the dynamics of the climate and energy systems as they discover how En-ROADS responds to their own climate-energy decisions. Methods. We evaluated learning outcomes from the Climate Action Simulation using pre- and post-simulation surveys as well as a focus group. Results. Analysis of survey results showed that the Climate Action Simulation increases participants’ knowledge about the scale of emissions reductions and policies and actions needed to address climate change. Their personal and emotional engagement with climate change also grew. Focus group participants were overwhelmingly positive about the Climate Action Simulation, saying it left them feeling empowered to make a positive difference in addressing the climate challenge. Discussion and Conclusions. Initial evaluation results indicate that the Climate Action Simulation offers an engaging experience that delivers gains in knowledge about the climate and energy systems, while also opening affective and social learning pathways.more » « less

Abstract As biodiversity loss and climate change accelerate, more people worldwide are engaging in conservation behaviors to “do their part.” Yet, individual behavior change alone is insufficient for the large‐scale, rapid change needed to address these crises. Relational organizing, which involves individuals reaching out to others in their social network, can enhance the speed and scale of conservation behavior change and address the complex, collective action nature of many conservation problems. However, many people practicing conservation behaviors in their own lives do not engage in relational organizing about conservation issues. Here, we suggest this may be the result of specific social‐psychological factors inhibiting people from reaching out to others. We summarize the evidence and offer a research and practice agenda to prioritize (1) understanding the social‐psychological barriers that prevent relational organizing, and (2) addressing these barriers through targeted outreach interventions to help scale and accelerate community action for conservation.more » « less

Abstract Per‐ and poly‐fluoroalkyl substances (PFAS) are interfacially‐active contaminants that adsorb at air‐water interfaces (AWIs). Water‐unsaturated soils have abundant AWIs, which generally consist of two types: one is associated with the pendular rings of water between soil grains (i.e., bulk AWI) and the other arises from the thin water films covering the soil grains. To date, the two types of AWIs have been treated the same when modeling PFAS retention in vadose zones. However, the presence of electrical double layers of soil grain surfaces and the subsequently modified chemical potential of PFAS at the AWI may significantly change the PFAS adsorption at the thin‐water‐film AWI relative to that at the bulk AWI. Given that thin water films contribute to over 90% of AWIs in the vadose zone under many field‐relevant wetting conditions, it is critical to quantify the potential anomalous adsorption of PFAS at the thin‐water‐film AWI. We develop a thermodynamic‐based mathematical model to quantify this anomalous adsorption. The model couples the chemical equilibrium of PFAS with the Poisson‐Boltzmann equation that governs the distribution of electrical potential in a thin water film. Our model analyses suggest that PFAS adsorption at thin‐water‐film AWI can deviate significantly (up to 82%) from that at bulk AWIs. The deviation increases for lower porewater ionic strength, thinner water film, and higher soil grain surface charge. These results highlight the importance of accounting for the anomalous adsorption of PFAS at the thin‐water‐film AWI when modeling PFAS fate and transport in the vadose zone.more » « less

Abstract Humans are able to thrive in a multitude of ecological and social environments, including varied environments over an individual lifetime. Migration—leaving one place of residence for another—is a central feature of many people's life histories, and environmental change goes hand‐in‐hand with migration, both in terms of cause and consequence. Climate change has amplified this connection between environment and migration, with the potential to profoundly impact millions of lives. Although climate‐induced migration has been at the forefront of other disciplines in the social sciences, evolutionary anthropologists (EAs) have given it little attention. In this paper we draw upon existing literature and contribute our EA perspective to present a framework for analyzing climate‐induced migration that utilizes theoretical approaches from a variety of social science disciplines. We focus on three overlapping dimensions—time, space, and severity—relevant to understanding the impact of climate change on human migration. We apply this framework to case studies from North America of people impacted by climate change and extreme weather events, including hurricanes, droughts, rising sea‐levels, and wildfires. We also consider how access to both economic and social resources influence decisions regarding migration. Research focused on climate‐induced human migration can benefit equally from the addition of EA perspectives and a more interdisciplinary theoretical approach.more » « less
