Trends and knowledge gaps in field research investigating effects of anthropogenic noise
Conservation Biology, Volume 35, Issue 1, Page 115-129, February 2021., 2021 Abstract Anthropogenic noise is a globally widespread sensory pollutant, recognized as having potentially adverse effects on function, demography, and physiology in wild animals. Human population growth and associated changes in urbanization, transportation, and resource extraction all contribute to anthropogenic noise and are predicted to increase in ...

Effects of spatial autocorrelation and sampling design on estimates of protected area effectiveness
Conservation Biology, Volume 34, Issue 6, Page 1452-1462, December 2020., 2020 Abstract Estimating the effectiveness of protected areas (PAs) in reducing deforestation is useful to support decisions on whether to invest in better management of areas already protected or to create new ones. Statistical matching is commonly used to assess this effectiveness, but spatial autocorrelation and regional differences in protection ...

Gongye shui chuli, 2002 论述了我国西部开发水的问题是一个关键问题,提出城市污水采用氧化塘(兼作蓄水塘)处理技术,具有兼顾污水处理与回用的需要;能大幅度降低工程投资与运行费用和合理控制城市水污染等优点。这一污水处理与回用技术对西部干旱缺水的城市和建制镇,实现利用污水资源,发展林业和污水土地深度处理,减免城市水污染将起到重要作用。研究表明,到2010年,当城市周边实现污水灌溉林农业的土地面积达到城区面积的2～4倍时,将有效促进干旱地区的生态林农业区开发,以及生态都市建设和城市化发展进程。

Gongye shui chuli, 1986 本文综合环境、经济和技术等方面因素,论述我国城市污水进行必要的集中处理,是比较经济合理的方案,提出大城市应主要发展二级污水处理厂,中小城镇开发氧化塘技术是较有前途的。经过努力,预计到2000年,我国城市污水将有40%通过处理达到标准并主要回用于城市或农业灌溉。城市水污染问题会得到较明显改善。

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.

Strangers on the ladder of the party‐state: Women in teaching in Nationalist Taiwan, 1940s–1980s
Gender &History, Volume 38, Issue 1, Page 273-288, March 2026.Abstract As the ruling party of a party‐state in China and Taiwan, the Nationalist Party (Kuomintang/Guomindang) built a close relationship with the teaching profession. Many teachers joined the party and there was a well‐trodden pathway from teaching into local representative politics and civil service.
