Abstract: <p>The 1980s in the United States have come into focus as years of extensive ideological and socioeconomic fracture. A conservative movement arose to counter the progressive gains of previous decades, neoliberalism became the nation's economic mantra, and détente was jettisoned in favour of military build-up. Such developments materialized out of a multitude of conflicts, a cultural… more Full Text: THE TECHNOLOGY OF CONSENT: AMERICAN SCIENCE FICTION AND CULTURAL CRISIS IN THE 1980s A Dissertation Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in the Faculty of Arts and …

Abstract: <p>This thesis is intended to support dependent-on-crops farmers to hedge the price risks of their crops. Firstly, we applied one-factor model, which incorporated a deterministic function and a stochastic process, to predict the future prices of crops (soybean). A discrete form was employed for one-month-ahead prediction. For general prediction, de-trending and de-cyclicality were used to… more Full Text: The Application of One-factor Models for Prices of Crops and Option Pricing Process A Thesis Submitted to Committee on Graduate Studies in Partial Fulfillment of Requirement for the Degree of Master of Science in the Faculty of Arts and Science TRENT …

Abstract: <p>Urban agriculture (UA) is becoming increasingly prevalent in Canadian cities. Despite this municipal zoning by-laws often do not address UA explicitly. Using eleven interviews of urban agricultural participants a case study of the City of Peterborough's zoning by-laws and the barriers they might present to UA was conducted. Research suggests that UA can provide many benefits to… more Full Text: An Analysis of Zoning By-laws and Urban Agriculture in the City of Peterborough, Ontario A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Arts in the Faculty of Arts and Science …
