Growing Demand and Uneven Supply: Eight Years of Nature Education in China 需求增长与供给不均:中国自然教育八年发展回顾
Integrative Conservation, Volume 5, Issue 1, Page 46-58, March 2026.ABSTRACT This study examines the role of nature education in advancing conservation and sustainability in China between 2014 and 2023. Drawing on national survey reports and historical–comparative methods, it analyses the dynamics of public demand, institutional supply, and practitioner capacity.

Integrative Conservation, Volume 5, Issue 1, Page 33-45, March 2026.The Asian Songbird Crises negatively affects so‐called master birds, species that are used to increase the song complexity of competitive songbirds. We assessed the trade in a master bird, the crested jayshrike, in Indonesia before and after its legal protection.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Low conductivity, slow ion‐diffusion, and limited reactive sites are common problems in electrocatalysts and electrode materials. In this study, a complex NiTe–CoTe heterojunction with abundant Te vacancies embedded in N, P, and F co‐doped hollow carbon nanorods (NiTe1−x–CoTe1−x/NPFC) was fabricated via a simple ionic liquid‐assisted ...

Whose Voices Are Heard? Parliamentary Committee Witnesses as Gendered Representatives
Politics &Policy, Volume 54, Issue 1, February 2026.ABSTRACT Are women sources of expertise for parliamentary policy discussions? In most parliaments, committees are the only venue where citizens can speak directly to the legislature; we argue that the proportion of women witnesses has implications for gender equality in policymaking. We present an original dataset of over 52,000 parliamentary committee

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...
