University Students' Utility Value of Learning About a Local or Nonlocal Environmental Socioscientific Issue: Written Reflections and Instructional Contexts

Journal of Research in Science Teaching, Volume 63, Issue 8, Page 800-820, October 2026.
ABSTRACT Socioscientific issues (SSIs) are central to science education, yet empirical research on learners' perceived relevance in SSI teaching and learning remains limited. Utility value is a relevance construct that refers to the perceived usefulness of learning for learners' lives.

Green's Functional for Second-Order Linear Differential Equation with Nonlocal Conditions

, 2012
In this work, we present a new constructive technique which is based on Green's functional concept. According to this technique, a linear completely nonhomogeneous nonlocal problem for a second-order ordinary differential equation is reduced to one and ...

An Ensemble Kalman Smoother for Online Paleoclimate Data Assimilation

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract An integrated hybrid ensemble Kalman smoother (IHEnKS) is proposed to optimally utilize proxy data from the past to the future for paleoclimate data assimilation (PDA). As an extension of the integrated hybrid ensemble Kalman filter, IHEnKS assimilates future proxies through cross‐time error covariances, which are estimated from an online PDA ...

Physics‐Informed Reservoir Characterization From Bulk and Extreme Pressure Events With a Differentiable Simulator

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Accurate characterization of subsurface heterogeneity is challenging but essential for applications such as reservoir pressure management, geothermal energy extraction and CO2 ${\text{CO}}_{2}$, H2 ${\mathrm{H}}_{2}$, and wastewater injection operations.

Testing the Limits of Surface QG Theory With Deep Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Surface Quasi‐Geostrophic (SQG) theory provides a closed‐form mapping from surface buoyancy to interior stream function under the assumption that interior potential vorticity (PV) vanishes (Q=0) $(Q=0)$. In realistic flows, however, the interior PV is typically nonzero.

Rural land rental markets in developing countries: Can survey design innovations improve land market participation statistics?

American Journal of Agricultural Economics, Volume 108, Issue 5, Page 1376-1401, October 2026.
Abstract A longstanding puzzle in the African land rental market literature is the often‐observed discrepancy between the number of tenants (renters‐in) and the much smaller number of landlords (renters‐out) in survey data. If this discrepancy derives from systematic biases in survey data responses on rental market participation, then the existing body

Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

Archaeometry, Volume 68, Issue 5, Page 994-1008, October 2026.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies

Mathematical Finance, Volume 36, Issue 4, Page 804-825, October 2026.
ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.
