Prinicipally because I cant get copies of these through my university here in Spain, so have no way of reading them. But, also, Im not well versed on the nuances of statistics, so tend to find that these articles go a little bit over my head. Thats why I was hoping for a bit of simpler advice of this listserv....!

Why don't you try reading the Beck and Katz articles to resolve your
confusion? They are quite accessible. David Greenberg, Sociology
