Urban Heat Islands Across Major U.S. Cities: ​The Relationship Between Surface Temperature & Socioeconomic Status, Sarah Irish, Eliza Hammari, Megan Green

FHSS Mentored Research Conference

The urban heat island (UHI) effect is a geospatial phenomenon prevalent across major U.S. cities which has significant implications for public health, energy consumption, and environmental quality. To better understand the impacts of UHI on various communities, we analyzed the correlation between surface heat temperatures and median household income across five large cities and three urban climates (arid, humid, and tropical) in the U.S.. We gathered data from the U.S. Census Bureau and other sources to create maps using ArcGIS Pro. Based on the maps and statistical analysis, UHI intensity is correlated with socioeconomic status. Further research is recommended to …

Local Nutrient Addition Drives Plant Diversity Losses But Not Biotic Homogenization In Global Grasslands, Qingqing Chen, Shane A. Blowes, W. Stanley Harpole, Emma Ladouceur, Elizabeth T. Borer, Andrew Macdougall, Erika Hersch-Green, Et Al.

Michigan Tech Publications

Nutrient enrichment typically causes local plant diversity declines. A common but untested expectation is that nutrient enrichment also reduces variation in nutrient conditions among localities and selects for a smaller pool of species, causing greater diversity declines at larger than local scales and thus biotic homogenization. Here we apply a framework that links changes in species richness across scales to changes in the numbers of spatially restricted and widespread species for a standardized nutrient addition experiment across 72 grasslands on six continents. Overall, we find proportionally similar species loss at local and larger scales, suggesting similar declines of spatially restricted …

Interactions Among Nutrients Govern The Global Grassland Biomass–Precipitation Relationship, Philip A. Fay, Laureano A. Gherardi, Laura Yahdjian, Peter B. Adler, Jonathan D. Bakker, Siddharth Bharath, Elizabeth T. Borer, W. Stanley Harpole, Erika Hersch-Green, George R. Wheeler

Michigan Tech Publications

Ecosystems are experiencing changing global patterns of mean annual precipitation (MAP) and enrichment with multiple nutrients that potentially colimit plant biomass production. In grasslands, mean aboveground plant biomass is closely related to MAP, but how this relationship changes after enrichment with multiple nutrients remains unclear. We hypothesized the global biomass–MAP relationship becomes steeper with an increasing number of added nutrients, with increases in steepness corresponding to the form of interaction among added nutrients and with increased mediation by changes in plant community diversity. We measured aboveground plant biomass production and species diversity in 71 grasslands on six continents representing the …

Between The Land And The Sea: Belizean Voices In Environmental Governance, Kris-An K. Hinds

USF Tampa Graduate Theses and Dissertations

Coastal communities around the world are at the epicenter of dynamic socio-environmental transformations driven by the impacts of climate change, shifting human–more-than-human environmental relationships, and the decisions made in response to these challenges. As environmental concerns intensify, the governance decisions made to address these impacts will determine the severity of the impacts and the future of affected coastal areas. In regions such as the Caribbean, Central America, and Latin America, environmental governance is complicated by uneven power dynamics, historical legacies of racialized environmental spaces, and the ongoing challenge of balancing national economic growth with environmental preservation. These transformations are not …

Adapting To Uncertainty: Strategic Decision Making In The Fresh Produce Supply Chain Under Fluctuating Market Conditions, Jacqueline Kelly

USF Tampa Graduate Theses and Dissertations

The global fresh produce supply chain faces increasing uncertainty due to economic volatility, shifting trade policies, logistical constraints, and evolving consumer demand. In this dissertation, I examine industrial purchasing decision-making grounded in the Industrial Buyer Behavior (IBB) framework. The study explores how supply chain experts navigate uncertainty, mitigate risks, and implement adaptive strategies to maintain efficiency and profitability.

Using a qualitative approach, this research draws on in-depth interviews with industry professionals to identify key factors influencing purchasing decisions, including supply chain resilience, technological advancements, sustainability, and geopolitical risks. Findings indicate flexible sourcing strategies, real-time logistical adjustments, and predictive analytics are …

A Survey Of Sampling Methods For Hyperspectral Remote Sensing: Addressing Bias Induced By Random Sampling, Kevin T. Decker, Brett J. Borghetti

Faculty Publications

Identified as early as 2000, the challenges involved in developing and assessing remote sensing models with small datasets remain, with one key issue persisting: the misuse of random sampling to generate training and testing data. This practice often introduces a high degree of correlation between the sets, leading to an overestimation of model generalizability. Despite the early recognition of this problem, few researchers have investigated its nuances or developed effective sampling techniques to address it. Our survey highlights that mitigation strategies to reduce this bias remain underutilized in practice, distorting the interpretation and comparison of results across the field. In …

Universal Health Care, Oregon, Jennifer S. Arnold, Bethany Clouse, Alec Martin

OHSU-PSU School of Public Health Annual Conference

Historically, the US has chosen not to fund universal health care at every opportunity, leaving our nation as the only industrialized country without some system of health coverage for our citizens and with the worst health care outcomes of any high-income nation in the world. Health care in Oregon is no exception. Our current health care system is financially unsustainable, harmfully complex, and socially unjust, as well as inequitably delivered. Too many Oregonians, because of their race, age, income, geography, or insurance, endure vastly different health care access, varied health care quality, and wide-ranging health outcomes. In 2019, the Oregon …

A Method For Describing The Problem Of Physician Distrbution In Rural Areasralph Ekwall, Ralph Ekwall

The Geographical Bulletin

In recent years much attention has been given to the problem of physician shortage and physician maldistribution. The first is con­troversial and not all the experts believe that it exists except as a part of the maldistribution problem. There is a fundamental agreement that a problem of maldistribution exists. The general nature of the problem is that physicians are dis­tributed too densely in small cities and large city suburbs and too sparsely in the inner city and rural areas. It is not the intent of this presen­tation to offer a solution to the problem, but to offer a method for …

The Evaluation Of Four Time Intervals Applied To A Synoptic Weather Situation In The United State, Fred E. Kohle

The Geographical Bulletin

synoptic meteorology almost always utilize the easily acquired National Weather Service weekly series of daily weather maps, issued every 24 hours at 7 A.M. eastern standard time (E.S.T.). These daily surface maps provide students with weather data from hundreds of weather stations in the continental United States. Students can use each map to compare and contrast weather patterns affecting several different parts of the country. A sequence of these daily maps allows students to attempt general weather forecasting using well-known weather relationships associated with the model middle latitude cyclone. They can then evaluate their forecasts by referring to the next …

Application Of 700 Millibar Synotic Climatology To Drought Analysis, B. Dey

The Geographical Bulletin

Large areas of the earth's surface experience occasional climatic fluctuations. Such fluctuations, integral to the weather system, often lead to drought or flood, and this influences crop production and commodity prices. Drought is a contributor to economic, social, and, on occasion, even political instability in both commercial and subsistence agricultural econ­omics. Particularly affected are areas such as India, China, parts of Europe, and the American Great Plains which include the Canadian "Prairies". Because of its dominantly agricultural economy, and because of its location well within a zone of frequent drought, the Canadian Prairies section has been selected for study. Past …

Diffusion Of The Decision To Drain Agricultural Land In Delaware County, Indiana, T. Silas Kasambira, Jr.

The Geographical Bulletin

The amount and quality of land are vital production factors in agriculture. In some Indiana counties, the agricultural land resource base is limited by the presence of excess water. The decision to drain potential agricul­tural land in Delaware County, In­diana, and the subsequent diffusion of that innovation has increased the amount and quality of land available for agriculture. Draining agricultural land is a practice which began in the eastern United States and diffused rapidly across the country during the 1800's. The practice was introduced into northern Indiana, which has a great deal of flat, marshy terrain as early as 1850. …

Jonas Wenger Hoover - 1889-1979 Dr. Commeaux, Malcolm Commeaux

The Geographical Bulletin

Jonas Wenger Hoover, a faculty member at Arizona State University from 1924 to 1943 died recently at the age of 90. His life was somewhat like a roller coaster, reaching highs and lows; for the first half of his life he was considered a gifted, in­telligent, and well-rounded man, and he was highly regarded as an author and teacher, but for much of his life he lived in obscurity and near the bottom of society. He is a forgotten man today, but his life can be a lesson to us all. Mr. Hoover was considered gifted in several respects. He …

Social Gaps & Urban Divides: How Social Factors Shape Economic Disadvantage In American Cities, Parker J. Peterson, Ruth Kerry

FHSS Mentored Research Conference

This research examines the relationship between nonmarriage, education, and socioeconomic disadvantage across census tracts in Boston, Los Angeles, and Salt Lake City. Statistical analyses reveal significant differences in never-married proportions between cities, with strong correlations between nonmarriage and community disadvantage. Even when controlling for other factors, nonmarriage remains a significant predictor of disadvantage, though spatial regression shows education is the strongest predictor in Boston.

The Formation Of Glacier Dirt Cones, Ryan M. Strickland, Matthew D. Covington

Geosciences Faculty Publications and Presentations

Glacier dirt cones are meter-scale cones of ice covered with sediment and rock. The cones develop through a process known as differential melt, whereby ice underlying thick debris melts more slowly than bare ice. We report observations of dirt cones on the Kuskulana Glacier, Alaska and develop a model that simulates the growth of dirt cones from debris-filled pits in the ice. With this model, we vary ice melt rates, hillslope debris diffusion rates and pit geometry. Cone heights scale with the square root of debris volume and growth occurs in three distinct stages: emergence, flux-controlled growth and melt-controlled growth. …

Beyond Data Deletion: Addressing Anticompetitive Conduct In The Era Of Machine Learning, Vaibhav Srikaran

Washington Journal of Law, Technology & Arts

Like a hamster wheel, the “virtuous cycle” of data collection, collation, and computation spins to create algorithms to assist modern business operations. Companies accumulate data by the terabyte with hopes that their army of data scientists can make sense of all the noise using machine learning. Potential profits encourage companies to seek out data—sometimes unlawfully through collusion. The use of unlawfully collected data in algorithms harms competition. Such data provides a competitive edge that is not accessible to all marketplace participants. Antitrust laws can police unlawful data sharing, but existing remedies are not effective for restoring competition.

Community Land Governance In Liberia: Implications For Tenure Security And Land Concessions, Julia R. Entwistle, Hanson Nyantakyi-Frimpong

Geography and the Environment: Faculty Scholarship

Throughout rural Africa, the intersection of customary traditions and statutory governance has often led to overlapping jurisdictions and conflicts over community land rights. In Liberia, this dynamic is particularly evident in the rise of commercial land concessions. This article examines the Liberian government’s approach to community land rights and its impacts on land tenure security, especially in the context of these concessions. This study employs a discourse analysis of Liberian land use policies alongside qualitative data from in-depth interviews with community members living near large-scale plantations. Despite historical erosion of community land rights, Liberian communities have adapted statutory frameworks to …

Law And Historical Materialism, Jeremy Kessler

Duke Law Journal

Since the financial crisis of 2008, left-leaning legal thought has experienced a renaissance within the American academy. From law and political economy to critical race theory to feminist legal studies to Marxist legal theory, new perspectives have flourished, and marginalized traditions have been revived and revised. These new perspectives and revisionist projects all share an intellectual debt to the critical legal studies (“CLS”) movement of the late 1970s and 1980s. That movement’s critique was focused on functional accounts of law: accounts that understood legal change as primarily responsive to the demands of extralegal social and economic forces. Some of those …
