How Do I Measure up? Social Influence and L2 Motivation in the Algorithmic Age
International Journal of Applied Linguistics, Volume 36, Issue 3, Page 1963-1974, August 2026.ABSTRACT Comparative thinking is a fundamental human drive and a hallmark of contemporary life. For social action, such as the learning and use of additional languages, a target for appraisal (an L2 attribute) is evaluated in relation to a comparison standard (an appraiser's standpoint).

Shuitu Baochi Xuebao, 2003 在野外调查分析的基础上,测定了沙棘、黄刺玫、油松以及草地和农田的土壤有机质和速效养分,采用新负极差法检验了有机质含量的差异性,结果表明:(1)黄土高原半湿润地区恢复植被能够显著提高土壤的有机质含量,且草地>沙棘>黄刺玫>油松;(2)植被恢复对土壤有机质的提高效益随深度增加而明显减小,土壤有机质有一定表聚性,草地和灌木林植被下更为显著;(3)不同植被类型土壤速效氮均有大幅度增加,土壤速效磷增幅较小;土壤速效钾在草地、黄刺玫植被下有少量增加,沙棘、油松林地却有所下降。

Scientists in power plays: How substantive were scientists' narratives during the COVID‐19 pandemic?
Policy Studies Journal, Volume 54, Issue 3, August 2026.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.

Gongye shui chuli, 2006 通过模拟试验，考察了自然有机物的浓度、分子质量以及溶液的pH、温度对地下水混凝除铁的影响，并研究了预氧化在混凝除铁中的作用。结果表明，有机物的浓度越高、分子质量越大，有机铁的去除率越高。当Fe2+与分子质量>10 ku的有机物络合时，用混凝除铁能取得良好的效果；当Fe2+与分子质量<4 ku的有机物络合时，采用预氧化混凝工艺能达到较好的除铁效果。在pH6.0~7.5的范围内，降低pH有利于混凝除铁。温度升高对混凝除铁有利。

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT This study introduces a dual‐layer protocol for diagnosing how formal institutional designs are implemented in practice in complex governance systems. The protocol builds two linked process maps; one for the formal rules and procedures (rules‐in‐form) and one for the routines actors actually follow in practice (rules‐in‐use).

Shuitu Baochi Xuebao, 2019 为探明碳氮添加4年后，土壤全氮、有机碳及其组分（可溶性有机碳、微生物量碳、轻组和重组有机碳）的变化特征，依托布设于甘肃省定西市安定区李家堡镇的不同碳源配施氮素田间定位试验，涉及秸秆、生物质炭、氮素3个因素，秸秆设置为不施、施用秸秆2水平）生物质炭为不施和施用生物质炭2个水平）氮素设置为不施氮、施纯氮50 kg/hm2、施纯氮100 kg/hm2 3个水平，共9个处理。结果表明：不同处理下土壤全氮、有机碳及其组分的含量均随土层的加深而降低。添加生物质炭对土壤全氮、有机碳及其组分均具有不同程度的提升效应 ...

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Disruptive innovations often diffuse faster than inherited policy institutions can classify, assign jurisdiction, and govern them. In these early phases, the central struggle is often not yet about the stringency of substantive standards, but about prior questions of what the innovation is (its legal and administrative classification), who is ...

利用生物地球化学模型研究草地生态系统土地变化对生态环境的影响
Shuitu Baochi Xuebao, 2003 分析了生物地球化学循环中植物—土壤生态系统的有机物动态,土壤有机质(SOM)主要库类——土壤C,N,P,S循环特点;阐述了土壤有机质的生物地球化学循环模型CENTURY结构。利用CENTURY模型模拟土地利用变化情形下内蒙古草原生态典型区土壤有机质动态。由数值模拟结果分析看,CENTURY对自然和人为活动影响下生态系统的土壤有机质动态有良好的模拟能力,同时又可有效地反映土地利用类型变化对生态环境和土壤侵蚀的影响。
