AI Agents, Joyful Assessment, and Third Space: Rethinking Assessment in the GenAI Era

Eliana Elkhoury, Xiaoyan Ma

This paper argues that assessment reform in the generative artificial intelligence (GenAI) era should move beyond defensive approaches focused primarily on preventing misconduct or detecting AI use. Synthesizing scholarship on assessment validity, relational and compassionate assessment, third space theory, and AI agents, …

How Do Profiles of Greed Map onto Multifaceted Well-Being?

Xiaoyan Ma, Dongdong Liu, Jing Dang, Chenggang Wu

Dispositional greed is often treated as a maladaptive trait, but its links to life satisfaction, presence of meaning, search for meaning, and psychological richness, from a person-centered approach, remain underexplored. We measured these constructs in 586 Chinese university students, then used correlation …

Development of fermentation and respiration bioprocesses for efficient nitrogen removal through microbial catabolism

Ji Qi, Xiaoyan Ma, Jian Chen, Qiwei Guo et autres

Conventional activated sludge processes are primarily designed for nitrogen and phosphorus removal, with carbon transformation regarded as a concomitant process that supports downstream denitrification rather than a proactively regulated process. Inspired by the metabolic division of labor in gut ecosystems, we proposed …
