Final answer:
A university president who engages in obscene phone calls to female students would best be diagnosed with Sexual Harassment Disorder.
Step-by-step explanation:
Sexual Harassment Disorder is an umbrella term that includes various forms of unwanted sexual behaviors, including obscene phone calls. It is a violation of the law and ethical standards, as well as a breach of workplace policies.
Marshall's behavior has caused significant problems at work and is grounds for termination. So therefore it is important for the affected students to report these incidents and for the university to take appropriate action to protect its students' well-being and ensure a safe learning environment.
