Orchestrating Green Transformation: How AI Adoption Enables Corporate Carbon Neutrality

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT As carbon neutrality has become a central goal of global climate governance, how firms achieve low‐carbon transformation has emerged as a critical research issue. However, prior studies have primarily focused on macro‐ or industry‐level analyses, offering limited and fragmented insights into how digital technologies—particularly AI—affect firm‐

Micronutrient Status in Children Suffering From Anorexia Nervosa: A Cohort of 349 Patients in a Referral Center for Eating Disorders

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is a serious illness in which more than half of all deaths are due to malnutrition. Critically low energy and protein intake are known causes of massive weight loss, whereas micronutrient deficiencies due to a low‐calorie food pattern remain poorly characterized in children with AN. Micronutrient deficiencies in
