University student agency in genre-sensitive writing: A longitudinal mixed-methods multi-case study of teacher and GenAI feedback
Learner agency is central to effective writing, and yet little is known about how students mobilize evaluative judgement when coordinating teacher feedback with feedback from generative artificial intelligence (GenAI) tools. This longitudinal mixed-methods multiple-case study (N = 10) traced how EFL university learners engaged with hybrid instructor–GenAI feedback across three genre-sequenced tasks (argumentative essay, AE; analytical report, AR;…
Enhancing student GAI literacy in digital multimodal composing through development and validation of a scale
It is widely acknowledged that Generative Artificial Intelligence (GAI) has exerted a greater influence on EFL learners' digital multimodal composing (DMC) process. GAI focuses on creating new textual and multimodal content using large language models (LLMs), and it puts different demands on EFL learners. Although much research has been conducted on EFL learners' AI literacy in various socio-cultural contexts, more attention should now be paid to…

Generation 1.5: Years in the United States and Other Factors Affecting Smoking Behaviors Among Asian Americans
While Asian men who came to the United States before 12 were less at risk for cigarette smoking than those who immigrated in adulthood, the pattern was the opposite among Asian women. Those who spent their childhood in the United States were more likely to smoke than those who came to the United States in adulthood. These patterns might result from the cultural differences between US and Asian countries, and bear policy relevance for the tobacco …

Evaluating the Impact of Improving Access on Consumption of Fruits and Vegetables in a Rural Community in Texas: A Modeling Study
Purpose: Most residents in rural regions of the United States consume fewer amounts of fruits and vegetables (FVs) compared with their urban counterparts. Difficulties in access to FVs often contribute to different consumption patterns in rural regions, aside from a lack of education or motivation for eating healthy foods. This article uses simulation methods to estimate the relationship between increasing food access and FV consumption levels in…

Rurality and Origin–Destination Trajectories of Medical School Application and Matriculation in the United States
Physician shortages are more pronounced in rural than in urban areas. The geography of medical school application and matriculation could provide insights into geographic differences in physician availability. Using data from the Association of American Medical Colleges (AAMC), we conducted geospatial analyses, and developed origin–destination (O–D) trajectories and conceptual graphs to understand the root cause of rural physician shortages. Geog…
