Testing reliability and validity of practitioner‐rated parental sensitivity: A novel tool for practice

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 45, Issue 2, Page 234-246, March 2024.
Abstract Improving parental sensitivity is an important objective of interventions to support families. This study examined reliability and validity of parental sensitivity ratings using a novel package of an e‐learning tool and an interactive decision tree provided through a mobile application, called the OK! package.

The game of energy transition: A game theoretical perspective on public participation procedures in infrastructure planning

open access: yesEuropean Policy Analysis, Volume 10, Issue 1, Page 39-60, Winter 2024.
Abstract For energy transition, infrastructure construction is often indispensable but also contested and potentially problematic for social cohesion. Through a game theoretical lens, we examine the basic configuration of infrastructure conflicts. Informed by the empirical example of German electricity grid planning, we discuss three approaches to ...

Progress developing the concept of other effective area‐based conservation measures

open access: yesConservation Biology, Volume 38, Issue 1, February 2024.
Abstract In 2010, the introduction of other effective area‐based conservation measures (OECMs) into international policy caused a paradigm shift in area‐based conservation, which included consideration of areas outside formal protected areas and places where biodiversity conservation may not be a management objective for the site.

火灾下膨胀型钢结构防火涂层的破损及其对钢构件升温过程的影响

open access: yesJianzhu Gangjiegou Jinzhan, 2021
为考察火灾下膨胀型钢结构防火涂层破损模式与程度的影响因素和涂层破损对钢构件温升过程的影响,对钢构件表面涂覆防火涂层组成的试件进行隔热性能试验和标准耐火试验。试验过程中测量并记录钢构件温度,试验结束后统计分析涂层的破损情况。研究结果表明,火灾下膨胀型钢结构防火涂层的破损模式为开裂和界面剥离,涂层脱落发生在降温过程。无荷载板型和短柱试件涂层的破损模式为Ⅰ型细小裂纹和Ⅱ型小裂缝,钢基材截面最大温差与截面平均温度的比值分别小于2.2%和6.3%。轴压长柱试件涂层的破损模式为Ⅲ型与Ⅳ型大裂缝(基材为碳钢 ...

输电线路雷电屏蔽模拟试验研究综述

open access: yesGaoya dianqi, 2016
输电线路雷电屏蔽模拟试验是研究输电线路雷电屏蔽性能最为直接有效的手段。文中从国内外输电线路雷电屏蔽模拟试验的研究现状出发,分别对缩比试验模型合理性、缩比模型导线接地方式、工作电压和施加电压极性4个方面进行理论分析和探讨。分析认为缩比试验模型与原系统应尽量在几何尺寸和物理参数具有相似性,推荐采用短波头操作冲击电压波进行大尺寸真型塔模拟试验;初步研究了导线接地方式对棒—缩比导线50%放电电压的影响,认为可通过光学观测等方式,研究缩比模型导线接地方式对放电过程的影响机理 ...
