International Journal of Applied Linguistics, EarlyView.ABSTRACT Collaborative writing has attracted increasing attention in English as a Foreign Language (EFL) instruction due to its potential to enhance learners’ writing competence. However, few studies have examined the comparative effects of collaborative versus independent writing on EFL learners’ individual performance, especially in higher‐order ...

Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19
Policy Studies Journal, EarlyView.Abstract The COVID‐19 pandemic sparked unprecedented experimentation in the German social assistance system, leading to changes previously considered impracticable by policymakers. This included a sanctions moratorium, easier access to benefits, and temporary cash transfers, all of which were advocated by welfare associations—key organized interests ...

Shuitu Baochi Xuebao, 2011 采用经典统计学方法,通过网格布点,研究黄土高原坡地表层土壤水分和容重在降雨后不同时段的空间变异特征。结果表明:(1)降雨后第1天,表层土壤水分和容重的变异程度分别为中等、弱变异性;在各坡向间土壤水分呈阴坡>阳坡>山脊的变化趋势,容重为阴坡>山脊>阳坡;(2)降雨后第20天,土壤水分和容重的变异程度均保持不变,但土壤水分在不同坡向间的数量特征发生改变(阴坡>山顶>阳坡),而容重的变化趋势保持不变;(3)表层土壤水分具有弱的时间稳定性,而容重的时间稳定性较强。(4)相关分析表明,降雨后第1天 ...

Democratic Values in Citizen Participation: What Citizens Prioritize in Participation
Policy Studies Journal, EarlyView.ABSTRACT Citizen participation is often initiated to strengthen democracy. While participatory innovations are typically assessed through normative frameworks emphasizing democratic values, little is known about which of these values are prioritized by citizens.

Shuitu Baochi Xuebao, 2020 土壤抗剪强度既可评价土壤侵蚀敏感性，也是反映耕层土壤耕作性能的重要参数。不同剪切方式下土壤抗剪强度指标存在一定差异，以紫色土坡耕地耕层土壤为研究对象，采用室内重塑土三轴及直剪试验方法，研究容重和含水率对紫色土坡耕地耕层土壤抗剪强度的影响，并分析了2种试验方法的差异性。结果表明：（1）紫色土坡耕地耕层土壤黏聚力（c）总体随容重（ρd）增大而增加，随含水率（w）增加而减小，三轴及直剪试验条件下黏聚力最大值均出现在容重1.4 g/cm3、含水率10%水平下，分别为32.33，21.78 kPa ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Sodium metal batteries hold significant promise for large‐scale energy storage due to the high theoretical capacity and abundant sodium sources, yet sodium‐metal anodes are hindered by dendrite propagation, unstable solid electrolyte interphase, and poor cycling efficiency arising from uneven Na deposition and volume changes.

野生动物学报, 2020 野生动物收容救护是动物园的重要职能,也是野生动物野外保护研究的补充。本文就重庆市动物园管理处2011—2016年收容救护猛禽情况进行分析与探讨:6年共收容救护猛禽22种133只,占重庆市分布猛禽种类的48.89%,含15种留鸟、1种夏候鸟和6种冬候鸟; 救护猛禽数量2011—2014年逐年下降,而后逐年上升; 救护猛禽的月份主要集中在1—3月和11—12月,为重庆市动物园管理处今后的收容救护工作安排奠定基础。

Dianci bileiqi, 2021 110 kV并联电容器装置具有单组容量大、电压等级高的特点,而其结构形式和运行工况又与传统并联电容器装置有所区别,因此研究其避雷器参数合理选取原则对于提高其经济性和安全可靠性具有重要意义。以特高压工程110 kV/240 MVA并联电容器装置为研究对象,对其正常分闸重击穿以及单相接地故障情况下单相重击穿时出现的过电压水平进行了理论分析,并在此基础上建立了避雷器吸收能量仿真模型,仿真分析了各种重击穿情况下避雷器的吸收能量以及运行工况对避雷系吸收能量的影响规律,最终提出了最严重工况下避雷器吸收能量的选取建议:

A Research on the Role of Government in the Village Collective Economic Development ——A Case Study of Fuzhou [PDF]
, 2016 村级集体经济是我国农村经济发展过程中的一项重要指标，是影响农村经济社会快速发展的重要因素。村级集体经济的发展问题，一直是中国社会的根本性问题，这个问题能否有效解决不仅关系着新农村建设的成败，也关系着经济社会能否持续稳定协调发展。村级集体经济的发展不仅要靠农民自身，还需要政府在政策、资金、人才、信息、管理方面的支持和引导，在这过程中，地方政府如何发挥作用，发展壮大村级集体经济，带动当地农村经济社会协调发展，已经成为我们需要共同研究和解决的重要问题。 本文以福州市为例，运用文献分析法 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Lithium‐selenium (Li‐Se) batteries have attracted considerable attention due to their high theoretical specific capacity and the intrinsically good electronic conductivity of selenium. Nevertheless, low active‐material utilization, parasitic side reactions, and sluggish reaction kinetics hinder their practical application.
