THE CURRENT ISSUE OF BIBLICA online has an article of paleojudaic interest:

John J. KILGALLEN, �Hostility to Paul in Pisidian Antioch (Acts 13,45) � Why?� , Vol. 84(2003) 1-15
Throughout Acts 13�14 Luke brings to the reader�s knowledge opponents of Paul who are called " the Jews" . The present essay attempts to clarify the meaning of this short-hand identification of Paul�s Jewish opponents. It seems best to understand these particular Jews in the light of zealotry which has its roots in centuries of vigorous defense of Jewish religious convictions.
