The Ecological U‐Turn in Nordic Forestry: Policy Learning, Measurement, and the Retrenchment of Ecological Ambitions

Environmental Policy and Governance, EarlyView.
ABSTRACT Since the 1990s, environmental policy has shifted toward ecosystem protection and biodiversity conservation, a development often described as an ecological turn. This article argues that in practice this turn has taken the form of an ecological “U‐turn,” as environmental ambitions are subordinated to production‐oriented objectives.

Policy Networks and Policy Entrepreneurship in the EU: Explaining Structural Policy Change in Pharmaceutical Innovation Incentives and Health Technology Assessment

European Policy Analysis, EarlyView.
ABSTRACT Policy process research has excelled in explaining structural policy change within national settings, but extensions and applications to the EU level have long proven challenging for scholars. Given that the EU is currently experiencing its longest period of Treaty stability since the 1980s—having evolved into a sui generis political system ...

Compromise kinetic-fluid model of electrons dynamics in electric propulsion devices with closed electrons drift as an alternative to the hybrid PIC-Fluid method

Авіаційно-космічна техніка та технологія
Electric propulsion devices with closed electron drift include Hall effect thrusters, plasma-ion thrusters with a radial magnetic field, and helicon thrusters, which are sources of plasma, ions, and electrons. Within the framework of the hybrid PIC-Fluid

Digital Rights Activism in Multilevel Governance

European Policy Analysis, EarlyView.
ABSTRACT Multilevel governance (MLG) without a clear hierarchical structure can create power imbalances among various actors, particularly in settings with overlapping jurisdictions and policy areas. This dynamic is especially pronounced in Internet governance, which faces a complex interplay of domestic laws, state interdependence, and heightened ...

Graph Neural Network‐Based Prediction of Building Energy Consumption

Energy Science &Engineering, EarlyView.
A graph neural network that encodes a multi‐zone building as a graph accurately predicts hourly cooling and heating loads across three distinct climates, outperforming Random Forest and XGBoost baselines and serving as a fast surrogate to EnergyPlus simulations for scalable building energy management.

“You just want to re‐open our biggest wounds, don't you?”: Homeplace ethnography as (polluted) environmental method

Feminist Anthropology, EarlyView.
Abstract When I was 12, my family told me a story about their community falling apart and coming together, a time when someone tried putting a nuclear facility in their (our?) hometown. Since we moved when I was too young to remember, the story had little significance until I embarked on a “hometown” ethnographic journey for my dissertation.

Rarefied Intake Flow in an Atmospheric-Breathing VLEO Hall Thruster

Aerospace
Atmosphere-breathing Hall thrusters (ABHTs) have emerged as a promising propulsion technology for very low Earth orbit (VLEO) satellites because they can utilize residual atmospheric particles as propellant, reducing the need for onboard propellant ...
