The Effects of Gen‐AI on Situated and Future‐Driven Academic Writing Motivation
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite the increasing use of Generative Artificial Intelligence (Gen‐AI) in education, there is still a significant gap in understanding its effects on the situated‐ and future‐driven motivation in academic writing. This longitudinal design‐based research sought to explore variations in academic writing motivation of 110 Chinese university ...

Off‐Task Talk to Manage Relationship Work During Student Group Work in Second Language Classrooms
International Journal of Applied Linguistics, EarlyView.ABSTRACT This paper presents a conversation analytic study on student relationship work in off‐task talk (OTT) during group work in foreign language classrooms. Often seen as disengagement from tasks, OTT's social and relational functions in student classroom group interaction and formation remain underexplored.

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?

, 2005 采用纳米压痕仪测量了Al2O3/SiCp复合材料中的热失配残余应力。根据研究材料的微结构和非均匀热残余应力分布特点,建立一压痕实验模型。在该模型中,实验材料被视为由若干含有单一SiC颗粒的Al2O3胞元构成,而热失配残余压应力均匀分布于胞元基体中。在考虑到浅压痕时材料表面粗糙和压头针尖曲率半径的影响的基础上测得的Al2O3 ...

World Water Policy, Volume 12, Issue 4, November 2026.ABSTRACT Biochemical oxygen demand (BOD) remains a core indicator of organic pollution in freshwater monitoring, but its role in water policy and practice is changing as water‐quality assessment moves toward predictive, integrative, and decision‐support approaches.

World Water Policy, Volume 12, Issue 4, November 2026.ABSTRACT This paper describes and analyzes recharge practices in Bács‐Kiskun County, Hungary, within what can be categorized as the farmer domain. Such locally embedded aquifer recharge practices remain underexplored in Hungary. Current research and funding largely focus on large‐scale Managed Aquifer Recharge (MAR) interventions emphasizing intended ...

Policy Studies Journal, Volume 54, Issue 4, November 2026.ABSTRACT Public consultations are a cornerstone of democratic policymaking, yet the sheer volume and heterogeneity of submissions often overwhelm traditional analysis. Emerging large language models (LLMs) offer new opportunities for making sense of such data, but their performance in contexts with high linguistic and technical diversity remains ...

Dizhen xuebao渝东南武隆地区志留系龙马溪组页岩储层发育，构造裂缝是页岩气运移和聚集的主控因素，而古构造应力场控制着构造裂缝的发育，对武隆地区页岩气的勘探开发具有较大影响。本文对武隆地区及周缘发育的节理进行分期配套处理，明确了武隆地区的古构造应力方向，同时通过岩石声发射实验计算得到了古构造应力的大小。在此基础上，利用ANSYS有限元软件建立了武隆地区志留系龙马溪组地层关键构造变形期的地质模型，并通过构造应力场的分析结果明确了该地区关键构造期的构造应力特征，以确定构造应力场数值模拟的边界条件，进而对构造应力场进行数值模拟。

Shiyou jixie, 2014 对压裂球进行受力分析和地面承压测试是开发高性能压裂球的关键。采用有限元数值模拟方法对压裂球进行了受力分析，研究了不同压力对压裂球内应力和塑性变形区域的影响规律，并通过承压试验测试了压裂球的承压性能。为了模拟真实的密封过程，选择显式动力方法定义分析步，在整个过程中认为球座无变形。分析结果表明，压裂球在不同压力载荷下的应力集中区域为球与球座接触区，随着压力的增大，应力集中区和塑性变形区逐渐向球心延伸；当压力超过110 MPa时，压裂球最大应力值已经接近材料的应力极限。
