Microplastics Toxicity and Life‐Threatening Impact on the Arabian Gulf: A Critical Review

Environmental Quality Management, Volume 36, Issue 2, August 2026.
ABSTRACT Microplastics (MPs) have emerged as a pervasive pollutant in marine environments worldwide, yet the Arabian Gulf remains underrepresented in global assessments despite its ecological and economic significance. The estimated mass of MPs entering the water of the Gulf ranged from 155 to 413.4 kt per year.

From Tasks to Traits: Can LLMs Infer Personality From Brief Assessment Center Behavior?

International Journal of Selection and Assessment, Volume 34, Issue 3, August 2026.
ABSTRACT Assessment centers (ACs) could provide behavioral foundations for trait assessment but demand substantial resources, especially the labor‐intensive human rating process. As organizations adopt large language models (LLMs) for automated assessment, we establish initial psychometric benchmarks for LLM‐based trait inference from AC behavior.
