Not Necessarily Farm‐Wives: The Working Women of Rural Aotearoa/New Zealand

New Zealand Geographer, Volume 82, Issue 3, December 2026.
ABSTRACT There's a perception farm‐resident women are farmers or farmwives (e.g., cooks, record‐keepers, errand‐runners). Yet most farm‐resident women record a non‐farm occupation in their census returns. This article investigates this anomaly. It looks at the changing status of farm and other rural women, the diversity of non‐farming careers they ...

Variation on Toxic and Inflammatory Potential of Coal Smoke of Different Sources From a Region With High Lung Cancer Risk

Environmental Toxicology, Volume 41, Issue 11, Page 1311-1322, November 2026.
ABSTRACT Excess lung cancer risk in Xuanwei and Fuyuan, China, has been attributed to household air pollution from use of a locally sourced smoky (bituminous) coal. However, the carcinogenic mechanisms remain unclear. Given the important role of inflammation in lung cancer development, this study compared the proinflammatory potentials of the ...

Influence of Polymer and Rubber Modification on Fatigue Crack Propagation in Asphalt Mixtures: A Cyclic SCB and Paris Law Investigation

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 11, Page 5099-5116, November 2026.
ABSTRACT Fatigue cracking is a major distress limiting asphalt pavement service life, and Paris law–based fracture mechanics offers a more mechanistic understanding than conventional fatigue testing. However, systematic characterization across diverse modifiers, dosages, notch depths, and temperatures remains limited.

Multi‐Model Machine Learning Framework for Predicting Drainage Performance of Porous Asphalt Mixtures

Applied Research, Volume 5, Issue 5, October 2026.
A multi‐model machine learning framework predicts four drainage indicators of porous asphalt mixtures from 11 macro‐void and meso‐pore descriptors. The stacking ensemble achieves R2 > 0.999, identifying connected void ratio, total void ratio, and volumetric mean pore diameter as dominant design variables. ABSTRACT Porous asphalt mixtures (PAM), such as
