Check out this thread here https://www.jehovahs-witness.com/topic/108487/rare-books (unfortunately the (brilliant) poster called Leolaia who had a copy no longer posts). You could however try messaging the original poster to see if he was successful in obtaining a copy.
Unless you can get it for free , save your $41 ( unless you can get somebody else to pay the bill! ). I have read a few of these University dissertations and generally they have been pretty disappointing , often with many errors and inaccuracies ( even those supposedly at PHD level ). It is very difficult to objectively and accurately conduct research into the Watchtower Society or JW members , especially for an "outsider" , even on the basis of an academic project , as active JWs don't generally respond and the Society refuses to co-operate in any research ( they probably wouldn't really appreciate being called a "sect" , for a start)!
This particular project dates back to 1980 , so it is somewhat dated now as well , as it pre-dates the purge of the early 80's and the major doctrinal changes of the mid 90's referencing the "generation" that time-shifted JWs expectations for the Millenium.
