Sun Bear Ecology and Conservation: Multiscale Habitat Associations in Southeast Asia 马来熊的生态与保护:东南亚地区的多尺度生境关联研究

open access: yesIntegrative Conservation, Volume 5, Issue 1, Page 125-136, March 2026.
We collated detections of the sun bear from new and previously published camera trap studies across its range. We then analysed these detections at two different spatial scales to assess the habitat associations and diel activity of this species. We found that the sun bear is tolerant to moderate habitat disturbances. ABSTRACT Degraded tropical forests,

Achieving Transboundary Water Security Through Water Innovations: A Framework and Cases

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Alternative sources of freshwater, provided by various innovations, have long been available to countries facing acute water stress. We hypothesize that avoiding and/or resolving conflict with neighbors—caused by the uncertainty of continued access to shared surface water and groundwater sources—is another driver of innovation adoption ...

张力腿漂浮式海上风电机组利用锚泊系统作为接地体的可行性研究

open access: yesDianci bileiqi, 2022
为了检验张力腿(tension leg platforms, TLP)漂浮式海上风电机组利用锚泊系统作为自然接地体的可行性,在CDEGS软件中建立了机组的接地体模型进行接地仿真试验,并模拟了海水电阻率、海水水位、海床土壤电阻率、海底锚固基础尺寸、张力腿数目等因素对接地电阻值的影响,仿真试验验证了当各个影响因素在最恶劣的情况下也能保证机组接地电阻值符合GB/T 50065-2011中的相关规定,证明了张力腿漂浮式海上风电机组利用锚泊系统作为接地体具有可行性。

CHINA’S LAND FINANCE AS ACTIVE MODE OF LAND DEVELOPMENT AND INFRASTRUCTURE DELIVERY: Reality, History and Prospects

open access: yesInternational 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 ...

Participation Disenchants: How Online Political Participation Decreases Online Political Efficacy in China

open access: yesRegulation &Governance, Volume 20, Issue 1, Page 35-63, January 2026.
ABSTRACT Existing literature largely agrees that authoritarian regimes establish channels for political participation to gather valuable information on citizens' anti‐regime sentiments and policy preferences and to supervise lower‐level bureaucrats and firms.

台海危机与风险管理:1987-2017为例 [PDF]

open access: yes, 2018
1987年,两岸长达38年的隔绝状态被打破后,人员往来和各项交流迅速开启。两岸由过去长期的对峙逐步迈向交流、对话与合作。三十年以来,两岸关系走过了一个高潮迭起的历程。尽管其间台海危机及两岸风险事件不断,但台海区域及两岸关系总体上维持了一个稳定的局面,有效地阻止了\"台独\"分裂势力企图把台湾从中国分离出去的野心。大陆对台海危机的管理基本上达到了预期的目标。随着中国大陆综合国力的快速提升,大陆在应对台海危机及其风险方面的管理能力不断提升,空间不断扩大。2016年度教育部人文社会科学重点研究基地重大项目 ...

波流作用下海上风机大直径加翼单桩基础局部冲刷试验研究

open access: yes, 2023
随着海上风机的大型化和风电场所在海域水深的增加,海上风机基础需要承受更大的水平荷载和弯矩荷载。加翼单桩能有效提升风机基础承载能力,但侧翼结构对桩基周围局部冲刷的影响目前尚不明确。在波流水槽中开展了大直径加翼单桩动床冲刷模型试验,研究纯流和波流共同作用下加翼单桩的冲刷特性。试验结果表明:加翼单桩周围局部冲刷特性受到来流强度、方向和类型的显著影响;当水流强度较小时,加翼单桩相较于传统的单桩基础具有较好的冲刷防护效果,防护效率最高可达20.7%;当水流强度较大或波流叠加情况时,加翼单桩的防护效应可能消失 ...

海洋环境对海上风场接地系统雷击暂态特性影响研究

open access: yesDianci bileiqi, 2018
海上风力发电产业的蓬勃发展面临日益严重的雷电灾害威胁,为有效指导海上风电机组的雷电防护研究,需要研究海洋环境对海上风场接地系统雷击特性的影响。利用PSCAD软件搭建简化海上风场模型,讨论海洋土壤分层环境下上层海水深度和下层土壤电阻率对风机接地系统雷击暂态响应的影响,分析增加接地体长度对于降低暂态过电压的效果。仿真结果表明:风机遭受雷击后,浪涌会传播至其他相连风机,距离雷击点越远的风机,塔底暂态电位幅值越低。下层海床土壤电阻率越大,风机塔底暂态电位幅值越高。上层海水深度越大,风机塔底暂态电位幅值越小 ...

Hurricane Impacts on the Population Genetics of an Endangered Ecosystem Engineer 飓风对一种濒危生态系统工程师的种群遗传学影响

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 641-651, December 2025.
Key Largo woodrats are a small and endangered island species, whose individuals tend to occur in family groups. Isolation from mainland populations, predation, and habitat fragmentation have caused genetic drift, leading to low overall diversity. Here, we found that a major category 4 hurricane promoted genetic diversity in the Key Largo woodrat ...
