The Politics of Transparency: Analyzing Online Information Disclosure in Spanish Municipalities

open access: yesPolitics &Policy, Volume 53, Issue 3, June 2025.
ABSTRACT This study aims to evaluate the existence of a mimetic behavior model in local governments‘ online information disclosure using spatial econometrics. To analyze this behavior, the Bidimensional Transparency Index is employed, which is an e‐disclosure measurement instrument that measures the local government‘s transparency level through two ...

Guanotrophy: Waterbirds Pay for Using Resources at Their Wintering Habitats 鸟粪营养学 :水鸟在越冬栖息地使用资源后留下回报

open access: yesIntegrative Conservation, Volume 3, Issue 4, Page 382-397, December 2024.
Significant waterbird colonisation was recorded in the wintering period (October through March in 2018–2019 and 2019–2020) in wetlands on Central Asian and East Australasian Flyways. Different limnochemical conditions influenced nitrate and phosphate concentrations.

黄土高原旱地果园土壤蓄水保墒技术定量研究

open access: yesShuitu Baochi Xuebao, 2000
据水量平衡原理,在集水技术基础上对黄土高原地区旱地果园不同土内蓄水保墒技术进行研究。通过测定果树植树带内土壤物理性状,定量地求算出影响根系生长的土层(0-60cm)范围内,各种蓄水保水措施的蓄水量,从而为解决干旱地区的缺水问题提供一些可行的途径。

富士苹果营养转换期肥料氮去向和土壤氮库盈亏研究

open access: yesShuitu Baochi Xuebao, 2017
运用15N同位素示踪技术,以5年生烟富3/SH6/平邑甜茶苹果为试材,研究了不同施氮水平(0,50,100,150,200,250 kg/hm2)对营养转换期富士苹果肥料氮吸收利用、土壤残留和土壤氮库盈亏的影响。结果表明,随施氮水平的提高,肥料氮的利用率逐渐下降,且树体吸收土壤氮素的比例逐渐降低,而来自肥料氮的比例逐渐升高;施氮1个月后,5.75%~12.99%的肥料氮被树体吸收,29.62%~39.74%的肥料氮残留在0—60 cm土体中,47.27%~64.64%的肥料氮通过其他途径损失 ...

Psychometric evaluation of the extended inclusion of nature in self scale in Chinese adults through the Rasch analysis

open access: yesPeople and Nature, Volume 6, Issue 6, Page 2431-2448, December 2024.
Abstract How humans connect with nature impacts the well‐being of both people and ecosystems. Being disconnected from nature can lead to attitudes and behaviours that ultimately damage our physical and mental health and cause irreparable harm to the planet.

热采水平井改善吸汽剖面技术研究及应用

open access: yesShiyou jixie, 2014
热采水平井蒸汽吞吐时水平段吸汽不均衡,造成水平段动用不均。鉴于此,对热采水平井改善吸汽剖面技术进行研究。首先,建立油藏井筒流动耦合模型及储层热流变形三场耦合模型,定量分析了油层物性参数、非均质性及注汽口位置对吸汽剖面的影响。然后,根据上述分析结果,设计了均衡注汽完井工艺管柱。该管柱可实现注采一体化及均匀注汽以及长水平段、非均质储层的均匀注采。现场应用结果表明,热采水平井改善吸汽剖面技术可以改善热采水平井长水平段的吸汽剖面,实现均衡注汽,提高水平井的动用程度。

Assessing predictions from optimal egg theory for an ectotherm relative to habitat duration 涉及生境条件持续时间的变温动物最优卵大小理论的预测评估

open access: yesWildlife Letters, Volume 2, Issue 3, Page 124-130, September 2024.
Median ovum size (mm; ±1 quartile) of wood frogs from three different wetland classes (long = long hydroperiods, short = short hydroperiods, and fish presence/absence) near Churchill, Manitoba, Canada from 2014 to 2019. Data points are individual egg mass values. Abstract Optimal egg size theory predicts females must balance investment per offspring to
