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

open access: yesNew 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 ...

Prediction of top-of-rail friction control effects on rail RCF suppressed by wear

open access: yes, 2017
Rolling contact fatigue (RCF) and wear, two major deterioration processes, limit the lifetime of rails. These deterioration processes are even more severe on the curves of tracks used by heavy haul trains.

The Bureaucratic Paradox of Citizen Agency: Institutional Crowding‐Out in Government‐Catalyzed Co‐Production in Shanghai, China

open access: yesGovernance, Volume 39, Issue 4, December 2026.
ABSTRACT Public service co‐production is often framed as a means of creating public value, yet its dynamics are complex when citizen‐led participation is catalyzed by strong public institutions. This mixed‐methods study examines government‐catalyzed, citizen‐centric co‐production in Shanghai, China, where the state provides institutional support ...
