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 ...

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.

, 1994 选择湖南省常德市江北城区水体为代表开展本项研究。结果表明，水体中污染指示菌，总大肠菌群（ＴＣ）和粪大肠菌群（ＦＣ）密度同ＢＯＤ＿５负荷以及综合污染指数Ｐ呈高度正相关。所以，污染指示菌指标，特别是粪大肠菌群指标足综合评价城市污水，尤其是生活污水污染的一个必不可少的重要参数。对该城区水体细菌污染的评价结果是，生活污水排放愈集中的地区，细菌污染愈严重。其中护城河水的ＴＣ密度超出我国地面水Ⅲ级标准４个数量级；ＦＣ密度超过ＷＨＯ娱乐用水标准３个数量级。护城河是细菌污染最严重水体 ...
