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 ...

Application of PID and switching in airship station-keeping and traffic flow [PDF]
, 2016 本文受国家自然科学基金课题“高空长航时定点飞艇基于特征模型的鲁棒 自适应控制”（61273199）和福建省自然科学基金课题“数据驱动的高空飞艇 飞行切换控制”（2016J01317）资助。 本文研究了平流层飞艇水平定点稳定和交通流瓶颈路段车流量控制。前者 是实现平流层飞艇长期驻空工作的一项关键技术，而后者有助于建立更加先进 的智能交通系统，解决城市交通拥堵问题，改善和提高居民生活水平。 本文主要研究这两类切换系统的稳定性。针对平流层定点稳定问题，研究 了一类对象连续，控制规则不唯一的切换系统 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Many existing rubrics for L2 argumentative writing prioritize form‐based linguistic accuracy and complexity while insufficiently addressing substantive argumentative rigor and effectiveness. This limitation is further complicated by cross‐cultural variation in rhetorical conventions and educational practices, which challenge the direct ...

Designs and Implementation of Motor Vehicle Parking Violation Reporting System Based on Android [PDF]
, 2016 随着我国近些年经济的持续高速发展，全国各地的机动车数量出现了异常快速的增长趋势。以杭州为例，在2013年限牌之前，每年机动车保有量的增速保持在20%左右，而道路面积的可行驶面积增长量仅为5%。更多的车辆带来的不仅仅是城市的快速发展和生活的便利，随之而来的交通事故和机动车违章也愈发频繁。虽然各种限行，交通管制，公共交通的发展等起到了一定的缓解作用，但在没有道路监控，交警数量不足等问题面前，机动车违章，尤其是违章乱停车的行为更是呈多发趋势。如何让广大人民群众加入到监督车辆违章停车的行列中 ...

Scientists in power plays: How substantive were scientists' narratives during the COVID‐19 pandemic?
Policy Studies Journal, EarlyView.Abstract Scientists who provide expert advice must engage with policy processes. Little is known about whether and how scientists deal with the political dynamics of policy processes that are inherent to policymaking. We study this question by building on the policy dimension concept within the Narrative Policy Framework.

Policy Studies Journal, EarlyView.Abstract Studies of lobbying typically look at the extent to which interest groups realize political goals on issues they actively lobby for. Little is known, however, about the extent to which interest groups attain their political goals without making an active lobbying effort.

Gaoya dianqi, 2005 通过化学方法检测了水中脉冲放电产生的H2O2,通过拍摄照片研究流注长度的变化。实验发现,在分别通入氮气和氧气的情况下,随着气体流量和放电时间的增加,H2O2的浓度逐渐增加;在电极间距为5cm,所加电压为35kV时,通氮气比通氧气生成的H2O2多,通氮气时流注长度较通氧气时要长。在电极间距为3cm,所加电压为21kV时,通氧气比通氮气生成的H2O2多,而流注长度差异不大。

Shuitu Baochi Xuebao, 2022 为探明黄壤坡耕地不同耕作措施下径流及可溶性有机碳(dissolved organic carbon,DOC)迁移途径与流失特征。以顺坡垄作、平作和横坡垄作措施下玉米种植坡耕地为研究对象,采用野外径流小区监测与室内分析相结合的方式,探讨自然降雨条件下坡耕地地表径流、壤中流及其DOC流失特征。结果表明:(1)种植玉米坡耕地径流量及DOC通量均受雨量等级影响显著,随雨量等级增大而增大,且玉米成熟期流失量均最大。(2)地表径流、0-20 cm壤中流和20-40 cm壤中流分别占总径流量的78.98%,9.05%,

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention
Policy Studies Journal, EarlyView.ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.
