Abstract: <p>Phosphorus (P) is an essential macronutrient. In south-central Ontario, foliar P concentrations are low and studies have suggested that P may be limiting forest productivity. Current catchment mass balance estimates however, indicate that P is being retained suggesting that P should not be limiting to tree growth. Phosphorus deposition is measured using bulk deposition collectors, which… more Full Text: Phosphorus deposition in forested watersheds: importance of pollen A Thesis submitted to the Committee on Graduate Studies in Partial Fulfillment of the requirements for the Degree of Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY …

Abstract: <p>Past research suggests that taking a process oriented approach, setting clear and concrete goals, and using both conscious planning and proactive coping are the best methods to be successful with goal pursuit. Also the literature has found that individuals scoring higher in general resourcefulness tend to be more successful at achieving goals than their less resourceful counterparts. My… more Full Text: WHY NOT GIVE-UP? A STUDY ON THE ROLE OF RESOURCEFULNESS IN GOAL PURSUIT.

Abstract: <p>Environmental variation can affect consumer trait expression and alter ecological and evolutionary dynamics in natural populations. However, although dietary nutrient content can vary by an order of magnitude in natural ecosystems, intra-specific differences in consumer responses to food quality have not been thoroughly investigated. Therefore, the purpose of my dissertation was to… more Full Text: ELEMENTAL VARIATION IN DAPHNIA: NUTRITIONAL, GENETIC, AND ENVIRONMENTAL FACTORS A Thesis 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 Science …

Abstract: <p>Northern and southern flying squirrels (Glaucomys sabrinus and G. volans, respectively) are experiencing a climate change induced increase in range overlap, resulting in recent hybridization. We investigated the occurrence of heterospecific communal nesting, a potential facilitator of hybridization, and aimed to confirm the presence of torpor, a potential barrier to hybridization, in… more Full Text: Social thermoregulation and potential for heterothermy: seasonal energy conservation strategies in flying squirrels A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in …

Abstract: <p>Emmanuel Levinas' philosophy focuses on the idea that no human subject exists outside of their relationship to other people. Each of us holds a profound degree of responsibility to and for all others. Since responsibility is fundamental to human (co)existence, it does not impede on freedom but proves that the sovereign individual is a dangerous myth: any philosophical, political or… more Full Text: “WHILE THE LONELY MINGLE WITH CIRCUMSTANCE” THE POLITICS OF ETHICAL SUBJECTIVITY 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 TRENT …

Abstract: <p>We propose a stochastic weather model based on temperature, precipitation, humidity and wind speed for Qatar, as a representative arid region, in order to obtain simulated values for a drought index. As a drought index, the Reconnaissance Drought Index (RDI) is commonly accepted in agriculture and is used to measure drought severity. It can be used to price weather derivatives to help… more Full Text: Modeling drought derivatives in arid regions: a case study in Qatar A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY …

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 …
