INFORMATION TO USERS This was produced from a copy of a document sent to us for microfilming. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help you understand markings or notations which may appear on this reproduction. 1.The sign or “ target” for pages apparently lacking from the document photographed is “Missing Page(s)”. If it was possible to obtain the missing page(s) or section, they are spliced into the Him along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure you of complete continuity. 2. When an image on the film is obliterated with a round black mark it is an indication that the film inspector noticed either blurred copy because of movement during exposure, or duplicate copy. Unless we meant to delete copyrighted materials that should not have been Aimed, you will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photo graphed the photographer has followed a definite method in “sectioning” the material. It is customary to begin Aiming at the upper left hand comer of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again—beginning below the Arst row and continuing on until complete. 4. For any illustrations that cannot be reproduced satisfactorily by xerography, photographic prints can be purchased at additional cost and tipped into your xerographic copy. Requests can be made to our Dissertations Customer Services Department. 5. Some pages in any document may have indistinct print. In all cases we have Aimed the best available copy.

I wish to express my gratitude to some whose support was made clear throughout my graduate studies at OSU. I wish to express deep appreciation to Dr. Donald W. Larson, who served as my major adviser. His guidance, encouragement, and friendly way of always being available were crucial and more than vital in the development of this dissertation. The suggestions and assistance gave by Drs. Norman Rask and Richard Meyer made a positive contribution to this research report. Many professors influenced the development of this investigation; among them I would like to thank Dr. Francis E. Walker for the valuable suggestions and comments about the methodological aspects of this work. This investigation was supported by many Brazilian people and institutions. Special gratitude is expressed to the Centro de Estudos e Pesquisas Economicas (IEPE) at the Universidade Federal do Rio Grande do Sul (UFRGS). This institution made possible my doctoral studies and iii gave great support to the data collection phase of this investigation. Special thanks are extended to Professor Eli de Moraes Souza, director of IEPE, and Dr. Humberto V. Richter, coordinator of the Programa de Ensino Agricola Superior (PEAS). Finally, I thank my family who have encouraged my educational efforts and especially to my wife, Maria das Gracas, for accepting my "absence" for such a long time and for sharing with me the rejoice of completing this proj ect. My doctoral program and much of the work reported herein were made possible by a fellowship from the Agency of International Development (AID). The Agency’s support is gratefully acknowledged. To the many unnamed, a very special thanks. iv VITA December 16, 1 9 ^ ............Born - Cruzeiro do Sul, Rio Grande do Sul, Brazil. 1968..........................B.S., Paculdade de Agronomia, Universidade Federal do Rio Grande do Sul, Porto Alegre, Rio Grande do Sul, Brazil. 1972..........................M.S., Centro de Estudos e Pesquisas Economicas, Univer sidade Federal do Rio Grande do Sul, Porto Alegre, Rio Grande do Sul, Brazil. 1973-197 8 ....................
