I think each of the topics listed meets the standard in different ways:
1. The psychological dimension of Alzheimer’s disease is interdisciplinary because it involves psychology, which examines how the disease affects memory, behavior, and emotions, and neurology, which focuses on the brain’s role in the disease. It could also connect to sociology, looking at how Alzheimer’s impacts families and caregivers, and ethics, which considers decisions about treatment and patient care.
2. The loss of manufacturing jobs to China requires input from several fields, including economics, which studies trade policies and labor costs, political science, which examines government policies and international relations, and sociology, which looks at how job losses affect workers and communities. Business studies could also be relevant, especially in understanding corporate decisions that lead to outsourcing.
3. The effects of closing fine arts programs in public schools connect to education, which explores how arts programs influence learning and engagement, psychology, which looks at how creativity and expression impact students, and sociology, which examines how removing these programs affects communities and opportunities for students. Public policy also plays a role, since funding and education priorities determine whether these programs stay or get cut.
