   Having determined the scores for depressiveness, drug abusive-

the three months, we computed the aggregate score for each the-
matic category by summing up the scores for the news articles. We
finally assigned the category with the highest score as a label for
a state. For instance, if the aggregate score of depressiveness for
the state of Iowa in the month of January 2020 is the highest of

characterizing each US state during each of the three months (Jan
2020 to Mar 2020). We demonstrate the power of transfer learning
by fine-tuning an attention-based deep learning model on a dif-
ferent domain and use the domain-tuned model for gleaning the
nature of media exposure. Specifically, we use background knowl-
edge bases for measuring depressiveness, drug abusiveness, and
informativeness of news articles. We found out DA-BERT identifies
the most number of state-to-month instances as being exposed
