Exploring English Language Learners’ Vocabulary Knowledge and Usage When Speaking
International Journal of Applied Linguistics, EarlyView.ABSTRACT Vocabulary forms a fundamental component of speaking ability, as it enables speakers to convey meaning accurately, fluently, and effectively. Although the relationship between vocabulary and speaking has been investigated to some extent, gaps remain in understanding the link between learners’ vocabulary knowledge and their speaking proficiency,

Gongye shui chuli, 2002 通过在废水中加入NaCl电解质,考察了电解阳极间接氧化法制药废水的处理效果。实验分析了废水中电解质NaCl对制药废水电解过程中CODCr、色度去除的影响,并对不同用量NaCl电解效果进行了对比。另外还用电解质Na2 SO4 、NaNO3 作了对比实验来说明NaCl产生的电解阳极间接氧化的存在。最后对甲红霉素废水进行中试实验,结果表明,NaCl电解产生的NaClO具有极强的氧化性,促进了CODCr的去除,同时还发现,废水中氨氮的存在不利于废水CODCr的去除。

, 2015 濱海水層的水位受到潮汐變動之影響，多年來，一直是地下水領域研究重點之一，特別是針對水層幾何形狀效應、多層滲漏水層，及水層異向性等問題。本研究考慮具異向性的海岸滲漏含水層系統，其上層為非侷限含水層，下層為侷限含水層，中間夾著滲漏層。水層的東西兩側是感潮河川，水層的南側海岸緊鄰海洋，我們針對這種三側受潮汐影響的U型滲漏含水層，建立其地下水流的數學模式，並推導其水位變動的解析解。若假設水層為均質、等向、未滲漏系統，則前人研究所導得的許多解，皆可視為本解析解的特例。另外 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Understanding learners’ English speaking self‐efficacy is essential for promoting effective oral communication in EFL contexts. However, variable‐centered research on English speaking self‐efficacy often overlooks heterogeneity among learners.

Compliance in Regulatory Gray Areas: The Case of the Organic Seed Standard
Policy Studies Journal, EarlyView.ABSTRACT Adaptive regulations, designed to balance flexibility with accountability, can embed provisions that unintentionally leave room for firms to shirk on their responsibilities by exploiting flexibility. We call these provisions “regulatory gray areas,” and ask: how should we understand (non‐)compliance in adaptive regulatory settings?

Beyond Evidence: How Framing Shapes Public Health Policies During Health Crises
Policy Studies Journal, Volume 54, Issue 4, November 2026.ABSTRACT Does the level of evidence that accompanies policy action depend on how a problem is framed, and on who frames it? This article examines these questions in the context of health crises. Bridging sociological and equivalence framing theories, it treats frames as preexisting interpretive schemes shared within communities of actors, whose ...
