Tundra Snow Cover Properties From In-Situ Observation And Multi-Scale Passive Microwave Remote Sensing, Andrew Rees

Theses and Dissertations (Comprehensive)

Tundra snow cover is important to monitor as it influences local, regional, and global scale surface water balance, energy fluxes, and ecosystem and permafrost dynamics. Moreover, recent global circulation models (GCM) predict a pronounced shift in high latitude winter precipitation and mean annual air temperature due to the feedback between air temperature and snow extent. At regional and hemispheric scales, the estimation of snow extent, snow depth and, snow water equivalent (SWE) is important because high latitude snow cover both forces and reacts to atmospheric circulation patterns. Moreover, snow cover has implications on soil moisture dynamics, the depth, formation and …

Place And Food: A Relational Analysis Of Personal Food Environments, Meanings Of Place And Diet Quality, Ellen Desjardins

Theses and Dissertations (Comprehensive)

This study investigates the relational layers of meanings that people experience at places in their food environment, and how individuals express a sense of place through their collective interactions with, and understandings of, food places. It also explores the patterns of difference among these meanings of place and sense of place in terms of their potential association with dietary quality. The context of this inquiry was two-fold: first, the need identified by several population health researchers and to re-imagine place as relational and include it in the study of behavioural responses to the changing food environment; and secondly, my interest …

An Apple A Day: Exploring Food And Agricultural Knowledge And Skill Among Children In Southern Ontario, Shannon Alberta Kornelsen

Theses and Dissertations (Comprehensive)

While the literature on food has somewhat addressed rudimentary food skills and their importance in the creation and maintenance of a healthy population, there remains a serious lack of research into the importance of food and agricultural skills and knowledge transference to children, especially given the rise in diet-related illnesses. This study focuses on the perceived importance of food and agricultural education initiatives, as well as the opportunities and barriers that exist within the elementary school classroom to incorporate food and agricultural topics, in the context of southern Ontario, specifically Wellington County. Drawing on Wilkin's concept of ‘food citizenship’ as …

A Time Series Analysis: Exploring The Link Between Human Activity And Blood Glucose Fluctuation, Eric A. Sadowski

Theses and Dissertations (Comprehensive)

In this thesis, time series models are developed to explore the correlates of blood glucose (BG) fluctuation of diabetic patients. In particular, it is investigated whether certain human activities and lifestyle events (e.g. food and medication consumption, physical activity, travel and social interaction) influence BG, and if so, how. A unique dataset is utilized consisting of 40 diabetic patients who participated in a 3-day study involving continuous monitoring of blood glucose (BG) at five minute intervals, combined with measures for sugar; carbohydrate; calorie and insulin intake; physical activity; distance from home; time spent traveling via public transit and private automobile; …

Identifying Potential Carbon Flux Responses To Shifting Hydroecological And Climactic Regimes In The Peace-Athabasca Delta, Caleb W. Light

Theses and Dissertations (Comprehensive)

The CO2 flux response of organic carbon stored in lake sediments and littoral peat contained in sensitive, northern wetlands may contribute to accelerating atmospheric CO2 concentrations. Temperature and moisture conditions are important variables that affect the rate and quantity of CO2 released to the atmosphere from organic matter stored in lake sediments and peat. Antecedent hydroecological conditions also influence the direction and magnitude of CO2 fluxes to the atmosphere in a changing environment. To better understand and characterize the role of antecedent conditions on CO2 fluxes, this study combines paleolimnological reconstructions with laboratory incubations of littoral peat and lake sediment …

Forestry-Based Livelihoods In Central Vietnam: An Examination Of The Acacia Commodity Chain: A Case From Thua Thien Hue Province, Vietnam, Robert Pietrzak

Theses and Dissertations (Comprehensive)

Forestry-based livelihoods in remote Vietnamese communities have been influenced in recent years by forest land allocation schemes, changes to property rights, and forest management devolution initiatives. Examples include the Five Million Hectare Reforestation Program, Project 327, and official “Red Books” that grant long-term land use rights and access rights to villagers. Major challenges to forestry-based livelihoods include disputes over land tenure, conflict between different levels of government, illegal logging practices and harvesting of NTFPs and competition over land for natural versus plantation forests. As a result, forest degradation and rural poverty continue to be debilitating obstacles to development in Central …

Spatial And Spatial-Temporal Analysis Of Grizzly Bear Movement Patterns As Related To Underlying Landscapes Across Multiple Scales, Barbara Lynn Carra

Theses and Dissertations (Comprehensive)

Studying the movements of grizzly bears (Ursus arctos) in Alberta is imperative for scientifically informed management practices. To properly balance industry requirements with conservation imperatives, it is necessary to understand the spatial and spatial-temporal movement patterns of grizzly bears as they relate to underlying landscape properties. As part of the Foothills Research Institute Grizzly Bear Research Program, this dissertation explored both fine and largescale movement patterns generated from global positioning system (GPS) radiotelemetry data.

Between 1999 and 2005, grizzly bears were captured and radio-collared across western Alberta. The temporal resolution of GPS data collection had a large impact …

Grounding Diaspora In Experience: Niagara Mennonite Identity, Cynthia Anne Jones

Theses and Dissertations (Comprehensive)

This qualitative case study grounds theoretical notions of diaspora in personal accounts of Russian Mennonites living on the Niagara peninsula of Canada. The focus is on successive, complex interrelationships with ‘place’ (in a fixed sense, and a globally connected sense), with attention to gender, generation, and life-stage. How have these individuals experienced diaspora, and how has this influenced their culture and identity? Interrelationships with place are examined within an analytical framework composed of three key elements as identified in diaspora literature: cultural hybridity, social heterogeneity (internal divisions), and responsibility flows. The results are both descriptive and theoretical, featuring first person …

Queer Appalachia: Toward Geographies Of Possibility, Mathias J. Detamore

University of Kentucky Doctoral Dissertations

Stereotypes about Appalachia abound through dubious and reductive representations of the ‘hillbilly’ icon. Sexuality and how it functions in Appalachia is usually cast from the outside as wild, violent, bestial, incestuous and generally base. Movies such as Deliverance and television shows such as The Beverly Hillbillies and The Dukes of Hazard render images of Appalachian sexuality as hyper-sexual, both naive and violent. These images of Appalachian sexual ignorance and violence that permeate popular culture have had problematic and reductive implications for rural gay/trans Appalachian folk. Mainstream gay culture has often used the perceived meanings of these images to circumscribe and …

Saving Saba Bank: Policy Implications Of Biodiversity Studies, Paul C. Hoetjes, Kent E. Carpenter

Biological Sciences Faculty Publications

Saba Bank has always been an area of special importance to the neighboring island of Saba in the Netherlands Antilles. Sabans traditionally fished on the Bank as far back as 1907, but increasing foreign fishing pressures on the Bank in the 1970s and 1980s forced many Saban fishermen out. Concerns were compounded by the suspicion that shipping was also damaging the benthic habitat of the bank. Fishery legislation, enacted in 1996, brought an end to unlicensed fishing and established Coast Guard enforcement on the Bank, but also led to protests from neighboring countries that previously fished on the Bank.Research was …

Improving The Instruction And Learning Of Topographic Maps Through The Use Of Geospatial Technologies, Troy Dean Schwemm

Dissertations and Theses @ UNI

Geographic information technologies (GIT) are spatially based technologies that include geographic information systems (GIS), remote sensing, and global positioning systems (GPS). Though GIT has been used in society for decades, and has grown tremendously in the last 10 years as advancements in technology have become available, its inclusion into the K-12 curriculum has not kept pace. As the educational reform movement places an ever increasing amount of pressure on schools to produce technologically literate, workforce ready graduates, school districts are scrambling to find creative, innovative ways to accomplish this task. Rather than learning passively, GIT allows students to construct their …

A Late-Quaternary Record Of Environmental Variability From Lake Sediment Cores, Wind River Range, Wyoming, Tyler Johnson

Dissertations and Theses @ UNI

Sediment cores from two alpine lakes in Wyoming's Wind River Range were collected and analyzed to establish a record of depositional and mineralogical variability. Due to the hydrologic setting and isolation of Fiddlers and Louis lakes, these cores yielded the longest continuous limnological record in the region that extends back nearly 20,000 years to full-glacial conditions, a rarity for alpine lakes in the western United States.

To develop a paleolimnological record for Fiddlers and Louis lakes, the sediment cores were analyzed using four laboratory techniques. These techniques included particle size analysis, x-ray diffraction, heavy mineral analysis, and loss-on-ignition. Radiocarbon ages …

Climatic And Spatial Variations Of Mount Rainier's Glaciers For The Last 12,000 Years, Michael Leslie Hekkers

Dissertations and Theses

Regional paleoclimatic proxies and current local climate variables and were analyzed to reconstruct paleoglaciers in an effort to assess glacier change On Mount Rainier. Despite the dry and generally warm conditions (sea surface temperatures (SST) -0.15°C to +1.8°C relative to current temperatures), the previously documented McNeeley II advance (10,900 - 9,950 cal yr B.P.) was likely produced by air temperature fluctuations. The average SST record and the terrestrial climate proxies show cooling temperatures with continued dryness between McNeeley II and the Burroughs Mountain advance (3,442 - 2,153 cal yr B.P.). The paleoclimate during the Burroughs Mountain advance was both cool …

The Transnational Networks Of Cultural Commodities: Peruvian Food In San Francisco, Kelsey Ann Brain

Dissertations and Theses

In a setting of increased movement, communication, and flows across space, commodity chain networks bring valued cultural commodities to transnational communities. This research examines the networks bringing foreign cuisine ingredients to Peruvian transnational communities in San Francisco, California. It seeks to answer three inter-related questions: 1) What are the origins and transportation networks bringing Peruvian food items to San Francisco; 2) Who controls and benefits from the movement of this food and resulting capital; and 3) How do networks vary for different classes of end consumers?

Chefs of ten Peruvian restaurants and ten Peruvian migrants in the San Francisco area …

The study is intended to generate findings to help policy makers plan appropriate strategies to improve the health of this highly vulnerable population group.

The findings reveal that women’s culturally and socially determined roles greatly impair their health and play an important role in health-seeking behaviour through a complex web of social, economic, religious/cultural and behavioural interrelationships and synergies that …

Participatory Planning For A Promised Land: Citizen-Led, Comprehensive Land Use Planning In New York’S Adirondack Park, Ann Hope Ruzow Holland

Antioch University Dissertations & Theses

New York’s Adirondack Park is internationally recognized for its biological diversity. Greater in size than Yellowstone, Everglades, Glacier, and Grand Canyon National Park combined, the Adirondacks are the largest protected area within the Northern Appalachian/Acadian Eco-Region and within the contiguous United States. Ecologists, residents of the Park, and others are concerned about rapid land use change occurring within the borders of the Park. Almost half of the six million acres encompassed by the Park boundary is privately-owned, where 80% of land use decisions fall within the jurisdiction of local governments. The comprehensive planning process of one such local government, the …
