Species Data And Vector Modeling: Evaluating Datasets For Improved Models Of Ixodes Ricinus Tick Distribution In Europe Under A Changing Climate, Steven Jones Dec 2022

Species Data And Vector Modeling: Evaluating Datasets For Improved Models Of Ixodes Ricinus Tick Distribution In Europe Under A Changing Climate, Steven Jones

Electronic Theses and Dissertations

To increase capacity for monitoring and surveillance of tick-borne diseases, publicly available tick distribution and climate change datasets are required to create accurate predictive distribution models. It is difficult, however, to assess model accuracy and utility when using incomplete datasets.  The more recent development of comprehensive tick databases for Europe and availability of climate change scenarios from multiple IPCC Assessment Reports allows for improved modeling efforts. Multiple tick datasets were combined and three climate change projections were compared by predicting current and future distributions of Ixodes ricinus ticks in Europe using the MaxEnt species distribution model. Overall, much of Europe …

Quantifying Spatial Heterogeneity Of Wild Blueberries And Crop Water Stress Monitoring Using Remote Sensing Technologies, Kallol Barai

Electronic Theses and Dissertations

The wild blueberry is one of the major crops of Maine, with significant economic value and potential health benefits. Due to global climate change, drought impacts have been increasing significantly in recent years in the northeast region of the USA, causing significant economic losses in the agricultural sectors. It has been predicted to increase further in the future. Changing patterns of the elevated atmospheric temperatures, increased rainfall variabilities, and more frequent drought events have made the wild blueberry industry of Maine vulnerable, suggesting the adoption of novel approaches to mitigate the negative impacts of global climate changes. Also, wild blueberry …

Key findings include: (1) the most significant variable across all three modes is temperature, (2) for bicycle-transit and bicycle use, there is a steady increase in ridership as temperatures increase …


Exploring Youth Relationships With Nature Using Qualitative Gis, Corey J. Martz Jan 2022

Exploring Youth Relationships With Nature Using Qualitative Gis, Corey J. Martz

Electronic Theses and Dissertations

Understanding youth relationships with nature—what nature is, where nature is located, and why nature is meaningful—is important for a range of contemporary issues, from promoting health and well-being to advancing a sustainable future. Relationships with nature are profoundly influenced by the lived experiences of youth, as they form social connections, have fun, learn, and go about their lives across an array of places—residences, schools, trip destinations, and places in between. One key to exploring youth relationships with nature, therefore, is engaging youth to document their experiences of nature in relation to specific places and developing methods that support them to …


Geovisualization And Open-Source Web Mapping Of Big Origin-Destination Data, A Test Case, Joseph Hiebert Jan 2022

Geovisualization And Open-Source Web Mapping Of Big Origin-Destination Data, A Test Case, Joseph Hiebert

Electronic Theses and Dissertations

Migration plays a key role in determining the health and success of cities, counties, and countries. It also plays a key role in determining the health and wellbeing of the individuals and families that undergo a migration event. This has led many scholars to map and study global migration patterns to understand how and why people move. While migration data are powerful, the origin-destination (O-D), tabular format of the data can be hard to interpret. To make O-D data more powerful, geographers can lean on computer cartography and new geovisualization techniques to help decision makers make sense of large, complex …


Care Infrastructure Accessibility And The Gender Wage Gap – A Way To Improve Women’S Ability To Equitably Engage In The Paid Labor Market?, Julia Schinnenburg Jan 2022

Care Infrastructure Accessibility And The Gender Wage Gap – A Way To Improve Women’S Ability To Equitably Engage In The Paid Labor Market?, Julia Schinnenburg

Electronic Theses and Dissertations

World-wide, women are less integrated into the labor force than men and if they are, they earn considerably less on average. This unequal treatment of women results in negative consequences for all members of society, as it harms women’s financial realities and also affects women’s care receivers due to a lack of resources that women can spend on their care giving. The research presented analyses how much the institution of better accessible care infrastructure could improve women’s ability to work for pay and decrease their daily workloads. The extent to which improved care infrastructure accessibility affects women’s lives is determined …


Relative Radiometric Correction Of Pushbroom Satellites Using The Yaw Maneuver, Christopher Begeman Jan 2022

Relative Radiometric Correction Of Pushbroom Satellites Using The Yaw Maneuver, Christopher Begeman

Electronic Theses and Dissertations

Earth imaging satellites commonly acquire multispectral imagery using linear array detectors formatted as a pushbroom scanner. Landsat 8, a well-known example, uses pushbroom scanning and thus has 73,000 individual detectors. These 73,000 detectors are split among 14 different focal plane modules (FPM), and each detector and FPM exhibit unique behavior when monitoring a uniform radiance value. To correct for each detectors differences in sensor measurement a novel technique of relative gain estimation that employs an optimized modified Signal-to-Noise Ratio through a 90˚ yaw maneuver, also known as side slither, is presented that allows for both FPM and detector level relative …


Fire Emissions In The Tropical Indonesia: Improved Estimation And Driving Forces Investigation, Xiaoman Lu Jan 2022

Fire Emissions In The Tropical Indonesia: Improved Estimation And Driving Forces Investigation, Xiaoman Lu

Electronic Theses and Dissertations

Indonesia has experienced frequent fires since the 1970s due to large-scale peatland conversion and extensive drainage for agricultural development. Fire emissions released from these fires have led to Indonesia being the world’s 3rd largest emitter of greenhouse gases in certain years. Given that fire emissions severely affect climate, weather, and the human environment, numerous approaches have been developed to estimate fire emissions. However, existing emission estimates differ largely by a factor of four in this tropical country because of frequent cloud interferences and low-temperature smoldering fires. Therefore, this dissertation aims to improve the quantification of Indonesian fire emissions through enhanced …
