Abstract: <p>When bioarchaeologists investigate ancient gender identity, they typically place skeletal remains into one of six sex assessment categories: male, female, possible/probable male, possible/probable female, ambiguous, and indeterminate. However, the study samples are often reduced to male and female reproducing a male/female gender and sex binary prevalent in the "Western"… more Full Text: REASSESSING BIOARCHAEOLOGICAL SEX DETERMINATION AND RESEARCH INTO GENDER AT THE EARLY ANGLO-SAXON WORTHY PARK BURIAL GROUND IN HAMPSHIRE, ENGLAND A Thesis submitted to the Committee on Graduate Studies in Partial Fulfilment of the Requirements for the …

Abstract: <p>There is an increasing global need for grid scale electrical energy storage to handle the implementation of intermittent renewable energy sources. Adiabatic compressed air energy storage is an emerging technology with similar performance to pumped hydro except it has the issue of heat loss during the compression stage. Previously, it has been considered to use sensible heat storage… more Full Text: INVESTIGATION OF USING PHASE CHANGE MATERIALS FOR THERMAL ENERGY STORAGE IN ADIABATIC COMPRESSED AIR ENERGY STORAGE 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>As part of a mandate to control the spread of Stratiotes aloides (WS; water soldier) in the Trent Severn Waterway, the Ministry of Natural Resources (MNR) created a management plan to eradicate WS. However, one of the biggest challenges in eradicating WS or any invasive aquatic plant is the ability to estimate the extent of its spread and detect new populations. While current detection… more Full Text: A Comparison of the Optical Properties of Stratiotes aloides and the Local Plant Community A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Degree of Master of Science in the Faculty of Arts and Science TRENT …

Abstract: <p>Sex-specific genetic structure is a commonly observed pattern among vertebrate species. Facing differential selective pressures, individuals may adopt sex-specific life historical traits that ultimately shape genetic variation among populations. Although differential dispersal dynamics are commonly detected in the literature, few studies have investigated the potential effect of sex-… more Full Text: SEX-SPECIFIC GRAPHS : IMPLICATION OF PARTITIONING POPULATION-BASED LANDSCAPE GENETIC ANALYSIS INTO SEX COMPONENTS A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the …

Abstract: <p>With the exponential growth of the Internet, performance is an issue as bandwidth is often limited. A scalable solution to reduce the amount of bandwidth required is Web caching. Web caching (especially at the proxy-level) has been shown to be quite successful at addressing this issue. However as the number and needs of the clients grow, it becomes infeasible and inefficient to have just… more Full Text: An Investigation of Load Balancing in a Distributed Web Caching System 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 …

Abstract: <p>Population density regulation is a fundamental principle in ecology, however there remain several unknowns regarding the functional expression of density dependence. One prominent view is that the patterns by which density dependence is expressed are largely fixed across a species, irrespective of environmental conditions. Our study investigated the expression of density dependence in… more Full Text: A MECHANISTIC ANALYSIS OF DENSITY DEPENDENCE IN ALGAL POPULATION DYNAMICS 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 …

Using a case study of twelve landowners in the Kawartha region, I explored motivations for restoring wetlands. Psychological research suggests that people who are more connected to nature and attached to place are more likely to behave sustainably.
