Narrative formatting, chronotopic orderings, and moralization in ex‐gay stories
Journal of Linguistic Anthropology, Volume 36, Issue 1, May 2026.Abstract Formatted stories rely on spatiotemporal cues to evoke recognizability through linearity, which prescribes a particular template for meaning‐making. This article examines stories narrated by ex‐gay members of a Christian organization in Singapore and considers how chronotopes within the stories are ordered to regiment ways of feeling for ...

Lessons learned from screening potential other effective area‐based conservation measures
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Other effective area‐based conservation measures (OECMs) are sites that deliver effective biodiversity outcomes irrespective of their management objectives. These areas are widely expected to play an important role in efforts to protect 30% of Earth by 2030.

仿生模式识别（拓扑模式识别）－－一种模式识别新模型的理论与应用
, 2002 本文提出了一种模式识别理论的新模型，它是基于“认识”事物而不是基于“区分”事物为目的。与传统以“最佳划分”为目标的统计模式识别相比，它更接近于人类“认识”事物的特性，故称为“仿生模式识别”。它的数学方法在于研究特征空间中样本集合的拓扑性质，故亦称作“拓扑模式识别”。“拓扑模式识别”的理论基点在于它确认了特征空间中同类样本的连续性（不能分裂成两个彼此不邻接的部分）特性。文中用“仿生模式识别”理论及其“高维空间复杂几何形体覆盖神经网络”识别方法，对地平面刚体目标全方位识别问题作了实验 ...

Conservation Biology, Volume 40, Issue 2, April 2026.Scaling area‐based conservation, including initiatives led or comanaged by Indigenous Peoples and local communities, is a flagship goal of the Kunming‐Montreal Global Biodiversity Framework. Conservationists often aspire to scale initiatives, but this is rarely achieved in practice. Identifying and addressing factors that limit initiative adoption (i.e.
