What is the author's tone in Signs of Life in the U.S.A. by Sonia Maasik?

The tone of the book is academic. The mood is for the most part objective, although there are more than eighty different authors involved in the overall book. Each author writes about something that he is knowledgeable about, and most of the authors are academics or professional writers. Even though there are nine different components of popular culture that are studied, there are about ten selections per component. Each article is written in a professional manner about some aspect of popular culture and from them, the student learns to develop critical thinking skills and writing skills.
