Using online reports of seahorse seizures to track their illegal trade

open access: yesConservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is a persistent and extensive threat to global biodiversity. Hundreds of marine fish species are subject to regulation under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but it is unclear how much protection species gain from CITES because information on marine fish ...

Characteristic of surface EMG signals during non-fatigue dynamic exercise in female quadriceps femoris(非疲劳动态运动中女性股四头肌的sEMG信号特征)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2011
采集9名女性受试者在不同负荷功率踏车运动中股四头肌的表面肌电(surface electromyography,sEMG)信号,观察其线性时频指标AEMG、MPF与非线性分析指标C(n)、%DET的变化规律,探讨女性股四头肌在非疲劳动态负荷下肌肉活动水平与sEMG信号特征指标之间的相互关系.结果发现,AEMG值随功率的上升而逐渐增加,与负荷功率呈线性相关;频域指标MPF与负荷的递增无明显关联;除%DET在股外肌的100 W和175 W阶段出现区分度外,非线性指标C(n)和 ...

Metadiscourse and Teacher Moves for Supporting Student Reasoning in Linguistics Classroom Interactions

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

Patriotic rabbits or toxic men? Media ideology, entextualization, and enregisterment on Chinese interfaces

open access: yesJournal of Linguistic Anthropology, EarlyView.
Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...

Institutions, in time: Designing feedback pathways for shared infrastructure transitions

open access: yesPolicy Studies Journal, EarlyView.
Abstract Electric utilities, challenged by a rapidly unfolding energy transition, use many informal institutions to bridge across technologies and sectors. Little is known, however, about how electric utility systems and other polycentric systems' institutions‐in‐use vary and evolve over time.

Capacity‐Learning Paradox: How Hong Kong and Singapore's Crisis Responses Shape and Are Shaped by Policy Capacities

open access: yesReview of Policy Research, EarlyView.
ABSTRACT This study examines the paradoxical relationship between policy learning and capacity: governments need certain capacities to learn effectively, yet these same capacities often emerge from previous learning experiences. Through a comparative analysis of Hong Kong and Singapore's responses to SARS and COVID‐19, we demonstrate how policy ...

非对称荷载对大跨度非规则单层网壳结构性能的影响

open access: yesJianzhu Gangjiegou Jinzhan, 2012
以某大跨度非规则单层网壳为研究背景,应用ANSYS通用有限元分析软件对网壳结构进行了建模并重点模拟了风荷载、雪荷载、温度效应等多种非对称荷载作用,进行了静力分析、特征值屈曲分析以及非线性稳定分析。得到了网壳结构在15种典型荷载组合下的内力、位移结果,分析了非对称荷载对网壳结构静力性能的影响;考虑了几何非线性、材料非线性、初始缺陷,得到了网壳结构在非对称荷载作用下的稳定系数,分析了非对称荷载对网壳结构稳定性能的影响。强调指出非对称荷载作用在大跨度单层网壳结构设计中的重要性 ...

分层交叉密肋平钢板组合剪力墙滞回性能研究

open access: yesJianzhu Gangjiegou Jinzhan, 2022
在已有研究的基础上,进一步探究分层型梯形加劲肋对内嵌组合平钢板剪力墙滞回性能的影响。设计出分2层和3层的交叉密肋内嵌组合平钢板剪力墙,均为双层单跨试件。利用有限元软件ABAQUS对其进行非线性和线性荷载作用加载,与已有的不分层交叉密肋平钢板组合剪力墙进行对比分析。研究结果表明:结构的承载力随着梯形加劲肋分层数目的增加而逐渐降低,但是其延性却随之增加,对比分析3个试件有限元模拟的结果,结构的承载能力和延性性能并非随着梯形加劲肋分层数目的增多而呈现线性变化 ...

Validating the parental reflective functioning questionnaire ‐ infant version using a rasch model

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 46, Issue 4, Page 445-458, July 2025.
Abstract Parental reflective functioning is the parent's ability to reflect on the psychological processes in their child and in themselves as a parent. Recently, an infant version of the Parental Reflective Functioning Questionnaire, PRFQ‐I, has been developed and validated using confirmatory factor analyses.
