Strengthening community‐based fisheries monitoring programs with Indigenous perspectives

open access: yesConservation Biology, EarlyView.
Abstract Community‐based monitoring (CBM) programs are increasingly recognized as essential for adaptive environmental stewardship. Yet, the CBM literature often highlights successful cases and privileges evaluations by external experts over those of community members themselves.

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

open access: yesConservation Biology, EarlyView.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Defining and identifying relevant stakeholders to advance effective conservation

open access: yesConservation Biology, EarlyView.
The challenge of defining stakeholders in environmental science and an approach for refining existing definitions. Abstract Stakeholder is a contested term that has spawned a multitude of ad hoc definitions. The ambiguity of these definitions has oftentimes impeded transdisciplinary research in environmental governance and conservation science because ...

Administrative Division Adjustment、Resources Allocation and Regional Economic Growth——The Case Of Chongqing Municipality [PDF]

open access: yes, 2016
十八大报告曾提出“优化行政层级和行政区划设置,有条件的地方可探索省直接管理县(市)改革,深化乡镇行政体制改革”的政策方针。分析行政区划调整对经济发展影响,探索行政区划调整对地方经济增长影响机制,对我国今后地方与区域经济的发展和改革方向把握上,以及检验能否通过采用行政区划调整实现推动经济发展无疑具有重要的现实意义。 在理论方面,本文引入了制度环境因素,对Solow模型进行了拓展,并假定行政区划调整是引起制度环境变化的主要因素,分析了行政区划调整行为对均衡增长路径上各经济特征的影响。 实证方面 ...

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty

open access: yesConservation Biology, EarlyView.
Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...

基于SVM-PSO混合算法的12kV开关柜触头盒双屏蔽结构三维电场优化研究

open access: yesGaoya dianqi, 2023
开关柜在长期运行过程中可能会因触头盒电场集中导致放电甚至击穿事故,采用双屏蔽结构是改善开关柜触头盒内电场分布的有效方法。为此,以KYN28A-12开关柜为研究对象,提出了一种基于SVM-PSO混合算法的开关柜触头盒双屏蔽结构三维电场优化方法。首先,在Comsol Multiphysics中建立了开关柜的三维仿真模型,分析了接地屏蔽长度、高压屏蔽半径和长度对触头盒、接地屏蔽和高压屏蔽表面场强的影响规律;然后,构建了含触头盒、接地屏蔽和高压屏蔽表面场强3个优化目标的评价函数 ...

The Analysis of Industrial Linkages and Business Cycle Synchronization:Between China,Japan and Korea [PDF]

open access: yes, 2016
在经济全球化不断发展的宏观背景下,各个国家之间的经济关系越加紧密,尤其是大国之间的经济波动动辄关乎到世界经济的发展,因此对于国家之间的经济周期协动性研究也就有了更为重要的现实意义。过去对于该课题的研究大多将目光集中于经济周期协动性在国家之间的传导机制与影响因素上,目前已经得到了很多的理论与实证结果。为了更进一步的将经济周期协动性与现实中的问题联系起来,本文创新性的从产业关联分析角度出发,在国家层面的系统性指标基础上更进一步,从具体的产业层面去寻找影响经济周期协动性的相关因素 ...

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities

open access: yesConservation Biology, EarlyView.
Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.
