International clinical practice recommendations on the definition, diagnosis, assessment, intervention, and psychosocial aspects of developmental coordination disorder – Chinese (Mandarin) translation

open access: yesDevelopmental Medicine &Child Neurology, Volume 61, Issue 3, Page E1-E35, March 2019., 2019
目的 本国际临床指南由欧洲残疾儿童学会(the European Academy of Childhood Disability,EACD)牵头制定,旨在解决发育性协调障碍(developmental coordination disorder,DCD)的定义、诊断、评估、干预以及与社会心理方面的临床应用关键问题。 方法 本指南针对五个领域的关键问题,通过文献综述和专家团队的正式讨论达成共识。为保证指南的循证基础,以“机制”、“评估”和“干预”为检索词, 对2012年更新以来提出的最新建议以及新增的“社会心理问题”和“青少年/成人”为检索词进行检索。根据牛津大学循证医学中心证据等级 (证据水平 [level of evidence, LOE]1–4) 将结果进行分类,最终转化为指南建议。并由国际 ...

Optimal Laser Strike Intensity to Realize “Nonlethal Pain Stimulation Deterrence” in Human‐Wildlife Conflict Management: Wild Boar as a Case Study 人兽冲突管理中 “非致命性痛觉刺激驱离技术” 的最优激光打击强度 —— 以野猪为案例

open access: yesWildlife Letters, Volume 3, Issue 4, Page 194-202, December 2025.
This study establishes the optimal nonlethal laser deterrence range (210–260 W, 1s) for wild boars, preventing agricultural damage while ensuring animal safety. Results demonstrate that efficacy requires seasonal power adjustments (≤ 285 W in winter) and precise targeting control—enabling effective, injury‐free wildlife conflict mitigation.

Environmental racism and air pollution: Pre and post the COVID‐19 economic shutdown

open access: yesReview of Policy Research, Volume 42, Issue 4, Page 949-981, July 2025.
Abstract Decades of research demonstrates that minoritized groups are disproportionately affected by swathes of harmful pollutants, including air pollution, even controlling for low income. Would significantly reducing individual car traffic help reduce the EJ gap?

Food insecurity and coping strategies of low‐income households in Tshwane, South Africa

open access: yesPoverty &Public Policy, Volume 16, Issue 4, Page 388-406, December 2024.
Abstract This study used principal component analysis to provide targeted policy interventions in response to livelihood coping strategies adopted by low‐income households in Tshwane (Pretoria), South Africa. The empirical findings are categorized into four food‐coping strategy groups.

The Dual Asymmetry Effects of Monetary Policy among Regions in China [PDF]

open access: yes, 2009
本文使用二步OlS法及MArkOV-SWITCHIng MOdEl对货币政策效应可能存在的双重非对称性进行实证研究,发现货币政策不仅存在方向上的效应非对称性,而且存在区域间的效应非对称性。在中国,中西部地区对扩张政策反应弹性小于紧缩政策反应弹性,东部地区对紧缩政策的反应弹性小于扩张性政策的反应弹性,即东部、中部、西部地区对于同一货币政策的反应弹性不同。In this paper, we make an empirical research on the dual asymmetry effects of

信息、政策冲击和中国股票、债券及外汇市场一体化——基于AG-DCC模型的金融市场动态相关性分析 [PDF]

open access: yes, 2009
本文运用Cappiello etal.(2006)提出的AG-DCC模型对中国金融市场的研究发现,中国股票、债券和外汇市场间存在明显的动态相关性,虽然"正向冲击"和"负向冲击"对金融市场波动并不产生明显的非对称效应,但对市场间动态相关性有着显著的影响,而且信息和政策冲击反映在动态相关性的结构变化上。最后,用平均动态相关性作为一体化指标对中国金融市场的考察发现,相对于欧盟市场间,中国股票市场一体化程度相当高,但股票和债券 ...

石墨-陶瓷电阻的冲击电压试验研究

open access: yesDianci bileiqi, 2013
冲击时间间隔和冲击次数直接影响石墨-陶瓷电阻的电压系数。研究表明:冲击间隔时间为10 s时电阻阻值变化幅度较小,电压系数较低,即最佳冲击间隔时间为10 s;随着冲击次数的增加,电阻的电压系数趋于常值,最佳冲击次数为100次。

The Research on Cash Reserve Proportion of Open-end Fund [PDF]

open access: yes, 2011
开放式基金因其可随时申购赎回的运作特点而获得了市场的普遍认可,至今在中国已走过了十年的高速发展历程。但这一运作机理也造成其难以克服投资者追涨杀跌的行为,并因此影响了自身的业绩表现。近年来由于中国A股市场的整体表现不佳,上证综指的弱势震荡导致投资回报率下滑,中国基金业整体的资产管理规模不增反减,诸如双汇发展停牌等市场的突发性冲击来也时有发生,基金管理人面临的净赎回压力和流动性风险形势日趋严峻。本文通过现金流的角度看待开放式基金的流动性风险,以开放式基金预留现金量作为研究对象,综合考虑了各方面的因素 ...

土壤频变性对接地装置冲击系数的影响分析

open access: yesDianci bileiqi, 2017
冲击系数是反映输电线路杆塔接地装置冲击特性的重要参数,对其进行准确计算是防雷优化设计和提升输电线路耐雷性能的基础。在深入分析土壤介质微观极化过程的基础上,引入Visacro-Alipio土壤频变特性公式,建立了考虑土壤电参数频变性的接地装置冲击特性数值模型;利用所建模型仿真分析了考虑土壤频变性时土壤电阻率、冲击电流波形等因素对接地装置冲击系数的影响规律。仿真数据分析表明考虑土壤频变性时接地装置的冲击系数与不考虑土壤频变性时的冲击系数相比有一定减小,在高土壤电阻率及陡波前冲击电流作用下其减小程度更明显。
