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 ...

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 ...

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.

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

open access: yesConservation Biology, EarlyView.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Emerging applications of large language models in ecology and conservation science

open access: yesConservation Biology, EarlyView.
Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

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 ...

Researches of the decoupled method for reliability-based optimization [PDF]

open access: yes, 2016
可靠性优化设计方法是工程结构设计中的一种非常具有优势的设计方法,其中,该方法的求解效率和求解精度是研究的重点。解耦策略是解决结构可靠性优化设计中包含复杂或隐式极限状态、多设计变量、小失效概率问题的一种高效可行的办法,它的关键在于建立失效概率的近似表达式,也就是求解失效概率函数。因此,研究高效求解失效概率函数近似的方法,以及提高优化效率和精度的解耦优化策略对于解决工程结构中的可靠性优化设计问题具有重要的作用。本文围绕上述问题展开研究工作,主要内容包括如下几个部分。 1.基于失效概率函数的概念 ...

Twelve Years Revisited: Translanguaging as Relational Pedagogy for Sustaining Language Learning Motivation

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...

固态变压器高压连接处绝缘结构优化设计

open access: yesGaoya dianqi, 2022
为了实现固态变压器绝缘性能的提升,满足其电压等级提升和紧凑型一体化设计的需求,利用遗传算法与电场仿真联合方法优化了固态变压器高压连接处绝缘结构。首先通过建立一体化固态变压器的绝缘结构模型,计算了稳态电场分布状态及局域电场集中位置,发现高频变压器与电力电子模块连接处接地截止点局域最高电场达6.97 kV/mm,高于空气击穿强度。其次设计了圆弧形模块连接绝缘结构将接地截止点埋入固体绝缘介质中,并通过遗传算法与电场仿真联合方法优化了圆弧形结构尺寸参数,使得连接处最高电场转移至固体绝缘介质内部 ...

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 ...
