Weather And Climate Information For Tourism, Christopher J. Lemieux, D.J. Scott
Geography and Environmental Studies Faculty Publications
The tourism sector is one of the largest and fastest growing global industries and is a significant contributor to national and local economies around the world. The interface between climate and tourism is multifaceted and complex, as climate represents both a vital resource to be exploited and an important limiting factor that poses risks to be managed by the tourism industry and tourists alike. All tourism destinations and operators are climate-sensitive to a degree and climate is a key influence on travel planning and the travel experience. This chapter provides a synopsis of the capacities and needs for climate services …
Identifying Potential Carbon Flux Responses To Shifting Hydroecological And Climactic Regimes In The Peace-Athabasca Delta, Caleb W. Light
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 …
Assessing The Vertical Accuracy Of Arkansas Five-Meter Digital Elevation Model For Different Physiographic Regions, Robert C. Weih Jr.
Assessing The Vertical Accuracy Of Arkansas Five-Meter Digital Elevation Model For Different Physiographic Regions, Robert C. Weih Jr.
Journal of the Arkansas Academy of Science
Digital Elevation Models (DEMs) represent the elevation of the earth’s surface. Scientists and decision makers have used DEMs to address questions relating to the earth’s landscape. This study assessed the vertical accuracy of Arkansas 5-meter raster DEM dataset produced in 2006 photogrammetrically, for three physiographic regions that represented a variation of elevations. The vertical accuracy of the DEM datasets was assessed by comparing their elevations to elevations collected using a surveying carrier phase Global Position System (GPS). To make comparisons between physiographic regions, paired t-tests using absolute elevation value difference and elevation difference along with the Absolute Mean Range Value …

The Transnational Networks Of Cultural Commodities: Peruvian Food In San Francisco, Kelsey Ann Brain
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 …
Influence Of Wetland Landscape Structure On Duck Nest Success At Malheur National Wildlife Refuge, Oregon, Daniel Robert Craver
Influence Of Wetland Landscape Structure On Duck Nest Success At Malheur National Wildlife Refuge, Oregon, Daniel Robert Craver
Geography Masters Research Papers
The decline of waterfowl populations and their requisite wetland habitats remains a concern. Because migratory bird refuges are often artificial landscapes of actively managed wetlands, and wildlife populations experience their greatest change during the breeding season, refuges should be designed to maximize breeding habitat. While past nest success studies have focused on at-nest variables, new approaches are needed to evaluate the effect of composition and configuration of plant communities at the landscape scale. This study aims to quantify landscape patterns within individual refuge management units to determine influence upon historical nesting success averages of ducks at Malheur National Wildlife Refuge …

Geography
Understanding the relationships between climate and carbon exchange by terrestrial ecosystems is critical to predict future levels of atmospheric carbon dioxide because of the potential accelerating effects of positive climate-carbon cycle feedbacks. However, directly observed relationships between climate and terrestrial CO2exchange with the atmosphere across biomes and continents are lacking. Here we present data describing the relationships between net ecosystem exchange of carbon (NEE) and climate factors as measured using the eddy covariance method at 125 unique sites in various ecosystems over six continents with a total of 559 site-years. We find that NEE observed at eddy covariance sites is …

The Study Of Radio Frequency Interference (Rfi) For Radio Astronomy In Some Remote Locations In Peninsular Malaysia., Syed Bahari Ramadzan Syed Adnan
Student Works (2010-2019)
Radio Frequency Interference (RFI) is the main parameter to find the best site for radio astronomy research development. The increasing levels of RFI will pose a big problem for researchers in the radio astronomy field. The radio astronomers are encouraged to choose sites as free as possible from interference. In this research we aimed to survey the RFI at frequency 1 MHz-2000MHz to look the overview of the RFI profile and at frequency 1419 MHz-1421 MHz to monitor the RFI profile at Hydrogen line frequency (1420.4 MHz). We chose Peninsular Malaysia as the research area for RFI observation. We have …
The Political Economy Of Affordable Housing Development In Suburban Hennepin County, Minnesota, Patrick Malloy
The Political Economy Of Affordable Housing Development In Suburban Hennepin County, Minnesota, Patrick Malloy
Geography Honors Projects
A shortage of housing affordable to low- and moderate-income households in job-rich suburbs is one of the biggest obstacles to upward mobility for those households, yet our understanding of the factors influencing the distribution of affordable housing development is weak. Focusing on suburbs in Hennepin County, Minnesota, I use qualitative case studies of eight cities and a statistical analysis of 39 to demonstrate that the geography of economic incentives to develop affordable units has the strongest influence. Contrary to common beliefs, opposition of middle-class suburbanites to affordable housing is a weak factor. Public policy should therefore focus on altering economic …
Spatial And Spatial-Temporal Analysis Of Grizzly Bear Movement Patterns As Related To Underlying Landscapes Across Multiple Scales, Barbara Lynn Carra
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
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 …
Tundra Snow Cover Properties From In-Situ Observation And Multi-Scale Passive Microwave Remote Sensing, Andrew Rees
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 …

Bringing Medicine To The Hamlet: Exploring The Experiences Of Older Women In Rural Bangladesh Who Seek Health Care, Md. Abul Hossen
Theses and Dissertations (Comprehensive)
The purpose of this study was to explore the experiences of older women in rural Bangladesh who seek health care. Qualitative methods were used to collect data from 17 older women in Bibirchar Union, Sherpur District, Bangladesh in June 2006. 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 …
Forestry-Based Livelihoods In Central Vietnam: An Examination Of The Acacia Commodity Chain: A Case From Thua Thien Hue Province, Vietnam, Robert Pietrzak
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 …
Controls On Terrestrial Evapotranspiration From A Forest-Wetland Complex In The Western Boreal Plain, Alberta, Canada, Scott M. Brown
Controls On Terrestrial Evapotranspiration From A Forest-Wetland Complex In The Western Boreal Plain, Alberta, Canada, Scott M. Brown
Theses and Dissertations (Comprehensive)
The Western Boreal Plain (WBP) of North Central Alberta consists of a mosaic wetlands and aspen (Populus tremuloides) dominated uplands. This region operates within a moisture deficit regime where precipitation (P) and evapotranspiration (ET) are the dominant hydrologic fluxes. As such these systems are extremely susceptible to the slightest to the slightest climatic variability that may upset the balance between P and ET. Vegetation composition is the dominant control on wetland ET, and itself is extremely dynamic within these wetland environments, which can be attributed to varying moisture regimes along with micrometeorological variations. To address this variability in …

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; …

Ecological Niche Modeling Of Potential West Nile Virus Vector Mosquito Species In Iowa, Scott R. Larson, John P. Degroote, Lyric C. Bartholomay, Ramanathan Sugumaran
Faculty Work
Ecological niche modeling (ENM) algorithms, Maximum Entropy Species Distribution Modeling (Maxent) and Genetic Algorithm for Rule-set Prediction (GARP), were used to develop models in Iowa for three species of mosquito – two significant, extant West Nile virus (WNV) vectors (Culex pipiens L and Culex tarsalis Coquillett (Diptera: Culicidae)), and the nuisance mosquito, Aedes vexans Meigen (Diptera: Culicidae), a potential WNV bridge vector. Occurrence data for the three mosquito species from a state-wide arbovirus surveillance program were used in combination with climatic and landscape layers. Maxent successfully created more appropriate niche models with greater accuracy than GARP. The three Maxent species’ …

Open Access Theses & Dissertations
Problems related to transportation and inspection of valuable or sensitive assets such as commercial products and materials, cultural items and works of art, and hazardous materials share similarities and can be modeled by a core set of abstract entities including a payload, a vehicle, a driver, and an inspector. To make the load handling capabilities of security monitoring and inspection systems more scalable, security can be increased by reducing the variability of transportation routes to a finite set of authorized routes between trip origin and destination locations. Then trip anomalies, which are unexpected trip variations, can be used in inspection …

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 …

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

This parallels research which aims to uncover alternative readings of community participation in forms of economic and social development. This research uses tourism as a lens to understand the economic subjectivity of communities engaged in tourism. Focusing on how the local populations understand, experience and participate in tourism, it paints a picture of the Perhentian Islands which challenges existing understandings of individual and community participation in tourism. …
Geographies Of Co2Lonialism And Hope In The Northwest Pacific Frontier Territory-Region Of Ecuador, Julianne Adams Hazlewood
Geographies Of Co2Lonialism And Hope In The Northwest Pacific Frontier Territory-Region Of Ecuador, Julianne Adams Hazlewood
University of Kentucky Doctoral Dissertations
This dissertation investigates the human dimensions of environmental transformations spurred by international climate change mitigation agreements—such as the Kyoto Protocol—that encourage lowering greenhouse gas emissions with ‘green’ market strategies like biofuel and ecological services development projects. It is methodologically grounded in “collaborative activist geographical methods” and theoretically based at the nexus of development, political ecologies, neoliberalization of Nature, and geographies of hope literatures. It examines the contradictory and complex ways that state “climate change mitigation development” projects surround and infiltrate the Indigenous and Afro-ecuadorian ancestral territories of the canton of San Lorenzo (Esmeraldas Province), located in the “Northwest Pacific Fronter …
Queer Appalachia: Toward Geographies Of Possibility, Mathias J. Detamore
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 …

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
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 …
