Bending Traditions To Avoid Breaking The Rulesthe Arthur, Illinois Amish, Page Redmond

The Geographical Bulletin

When the people of the Amish faith fled religious persecution in Europe and arrived in Pennsylvania about 1727, they came not to start a new life, but to preserve the old ways of living and farming.1 However, the reality of the outside has crept into their sheltered culture in the form of land shortages and higher prices for that land which does exist. These pressures, coupled with the all too constant awareness of the world outside their culture and its many changes and advances, have caused a weakening in some of the once strictly held traditions. From the outside, it …

Rural Development Versus Rural Preservation: Conflicting Usda Land Use Programs And Policies, Susan Oglesbee Burt

The Geographical Bulletin

With the mounting cost of farm ownership and operation, and the rapid increase in urbanization, the issue of farmland preservation has come to the forefront in many states, counties, townships, and villages. These factors, combined with inflation, severe fluctuations in the economy, and restrictions in the use of natural resources, have brought about heightened concern on the part of farmers in recent years. Farmers and rural communities are seeking alternative ways to cope with these conditions. Sale of their land to the highest bidder is one option that often results in conversion of prime agricultural land to other uses. The …

Suburban Land-Use Policies And. Community Pressure Groups In Southfield, Michigan, Joseph H. Kogelmann

The Geographical Bulletin

Creation and preservation of affluent suburban communities is dependent upon the existence of political expedients, whose primary function is to insure perpetuation of exclusionary socioeconomic barriers. Local land-use policies, as determined by municipal zoning regulations and building codes, have become mechanisms by which the status quo is maintained. The content of local land-use policies is particularly susceptible to political influence of community pressure groups. These groups are often a major force in the community decision-making process as they seek to mold local public policy in accordance with their own conceptions. Suburban elected officials have been extremely responsive to demands of …

Seasonal And Annual Precipitation Efficiency In The Eastern United States·, Jeffrey T. Lutz

The Geographical Bulletin

PreCipitation efficiency (Pe) is the percentage of the average atmospheric water vapor above a station that is released and falls to earth as measurable preCipitation in a given time period. Pe is a single parameter describing the efficiency of atmospheric mechanisms in releasing moisture. Temporal and spatial variations in Pe are controlled primarily by synoptic atmospheric systems. The relationship between atmospheric systems and seasonal! annual variations in Pe is investigated for the United States east of the Rocky Mountains. Regional variations in seasonal and annual averages of Pe suggest the relative effectiveness of dynamic and thermodynamic preCipitation mechanisms. Basically, the …

Gtu- A Regional Perspective, Leon C. Hallman

The Geographical Bulletin

These listings are indeed similar, both placing emphasis in the same general areas of concern and suggested activity. However, I bel ieve a dichotomy exists, not between GTU's brochure and the Association of College Honor Societies Booklet of Information, 1981-82, but HERE within Gamma Theta Upsilon, an Interna7 tional Geographical Honor Society. Where does it say: recognize academic and mental achievements, recognize excellence of performance, reward and recognize the attainment of scholarship of a superior quality? GTU's stated purposes do not include these ideas or concerns. GTU's purposes are to create interest, to strengthen training, to make geography practical for …

Crucible Of Excellence: The Honor Society, O. Orland Maxfield

The Geographical Bulletin

It has been some time since I have heard the rather piquant phrase, "to defend one's honor." Indeed, I do not often hear the word "honor" or read of it in the current mass media. It is as though we take "honor" for granted or it has been relegated to the zone of discard along with integrity and virtue. Perhaps we have become jaundiced by the everyday, commonplace, dishonorable actions of political and business figures, and sometimes even of our closer acquaintances. Think for a moment of the aphorisms relative to honor that you have heard all of your lives. …

Editor's Comments, Robert M. Ward

The Geographical Bulletin

Once upon a time in the land of academia, there existed an esteemed Department of Geography. It was steeped in tradition and was recognized by its peers as being among the foremost academic departments in the world. Yet this recognition was inadequate to spare it from an abrupt termination. This Department of Geography whose allegiance was once claimed by such notable geographers as Carl Sauer, Preston James, George Kish and others was sentenced to extinction by the Board of Regents on June 19, 1981. It is small consolation that the doors of the Department will officially close during mid-1982. I …

Hedging Energy Transition: Green Hydrogen, Oil, And Low-Carbon Resilience As State Strategy In Namibia, Meredith J. Deboom

Faculty Publications

Policy frameworks increasingly portray energy transition as a mechanism for achieving a range of resilience- related goals, including socio-economic development and energy security. Energy transition is often character ized as a particularly important resilience strategy for lower-income states in the Global South, which face the simultaneous challenges of decarbonization and development. Yet these states, many of which have fossil fuel resources, face distinct constraints and risks in navigating energy transition, including the possibility that promised funding for low-carbon energy projects will never come to fruition or that global decarbonization will be deferred or abandoned completely. This article uses the case …

The FIREX-AQ campaign took place in August 2019 and involved two aircraft and multiple coordinated satellite observations. This study applied and evaluated a self-supervised machine learning (ML) method for the active fire and smoke plume identification and tracking in the satellite and sub-orbital remote sensing datasets collected during the campaign. Our unique methodology combines remote sensing observations with different spatial and spectral resolutions. With as much as a 10% …

Reflections On Preparing Regional Chapters For Nca5, Abby Frazier, Allyza R. Lustig, Michael Chang, Emile H. Elias, Renee A. Mcpherson, Victoria W. Keener, Zena N. Grecni, Henry P. Huntington, Ellen L. Mecray, Kimberly M. Wood, Kathie D. Dello, Patricia Chardón-Maldonado

Geography

Regional chapters in the National Climate Assessment (NCA) report provide a comprehensive synthesis of how climate change is impacting United States regions and are extensively used to support climate change decision-making by local communities and policymakers. The regional chapter author teams are tasked with assessing the climate trends, risks, and responses across a range of sectors and across a vast and diverse geography, while making content locally relevant. Regional chapters have evolved in many ways since the third NCA (NCA3), often shifting from focusing on climate stressors and hazards to addressing more diverse human-centric impacts (e.g., human health), inequities, and …

Best Practices For Applying And Interpreting The Total Operating Characteristic, Tanner Honnef, Robert Gilmore Pontius

Geography

The Total Operating Characteristic (TOC) is an improvement on the quantitative method called the Relative Operating Characteristic (ROC), both of which plot the association between a binary variable and a rank variable. TOC curves reveal the sizes of the four entries in the confusion matrix at each threshold, which make TOC curves more easily interpretable than ROC curves. The TOC has become popular, especially to assess the fit of simulation models to predict land change. However, the literature has shown variation in how authors apply and interpret the TOC, creating some misleading conclusions. Our manuscript lists best practices when applying …

Could It Be Cold War? How Sino-American Tensions Are Unfolding In The South Pacific., Peter R. Caldwell

Senior Theses

This thesis assesses the impacts of geopolitical competition between the United States and China, focusing on the South Pacific as a primary theatre for this great power contest, and investigating the uses of foreign aid by regional powers to effect both the geopolitical alignment and domestic policies of the developing states of the South Pacific. This paper finds that foreign aid to these South Pacific States is geopolitically motivated, and induces greater attention from competing regional powers, furthering the ongoing competition. This paper first provides an overview of the evolving political situation in Kiribati, a Pacific Island Country which has …

Flood Risk Assessment In Humanitarian Contexts: A Remote Sensing And Gis Methodology Applied To Nyarugusu Refugee Camp, Tanzania, Carolyne Vincent Mbirika

Theses

Flooding is a global challenge, with effects mostly experienced in developing countries due to insufficient data for effective flood risk assessment and management. Refugee settlements are particularly vulnerable to flooding due to their remote locations, high population density, and temporary shelters, necessitating flood susceptibility mapping to effectively mitigate risks and minimize damage prior to flooding events. This study assessed flood susceptibility in the Nyarugusu refugee camp, Tanzania, through Multi-criteria Decision Analysis (MCDA) and Analytical Hierarchy Process using remote sensing and Geographic Information Systems (GIS) approaches. The flood susceptibility map that resulted from this process categorizes flood-prone areas into three classes: …

Dairy farming is the largest agricultural industry in New England, with corn being a primary crop to feed these cattle. This project seeks to understand how climate modeling and crop modeling are and are not useful for these corn farm decisions, and contributes research about what types of information are useful and available to farmers making adaptation decisions. Crop modeling over New England reveals that corn farming in …

Suspended Agency And The Habitus Of Waiting In A Migrant Shelter In Tijuana, Liam K. Ogden Iii

Senior Theses

This thesis explores idea of suspended agency and the development of a habitus of waiting within a women and children’s migrant shelter in Tijuana, Mexico. Relying on ten days of participant observation and an interview with a shelter director, I examine the lived experiences of residents, workers, and myself as a researcher navigating humanitarian space. Shelters are designed to be short term spaces, but migrants are often forced into long-term, uncertain stays due to restrictive border policies and structural barriers, resulting in a social stasis defined by boredom, anxiety, and monotony within the shelter. Drawing on Bourdieu’s concept of habitus …

Between Borders And Belief: Perspectives Of Aid Workers On Religion In A Migrant Shelter In Mexico, Kendall O. Roy

This thesis seeks to understand the significance of religion in the Central American migration context through the eyes of humanitarian aid workers. It is based on interviews that I conducted in May of 2024 with staff members at a migrant shelter in Mexico, analysis of prior scholarship, and building upon an understanding of relevant religious history in Latin America. I will delve into trends that the aid workers observed in areas such as religious practices and beliefs of migrants, shelter functions that addressed and nurtured spiritual well-being, and the influence of the Church as an institution on humanitarian aid work. …

Enhancing Remote Sensing Imagery Temporal Resolution Using Starfm Data Fusion Approach For Improved Land Surface Monitoring, Ahmadreza Pourghodrat

School of Computing: Dissertations, Theses, and Student Research

High-resolution remote sensing imagery plays a critical role in various domains, such as farm-level agricultural operations, environmental monitoring, and natural resource management. However, data with high spatial resolution typically have low temporal resolution, and those with high temporal resolution often lack spatial detail. For example, Landsat 8 and 9 satellites deliver high spatial resolution images with a 30-meter pixel size but suffer from low temporal resolution, with a 16-day revisit cycle. In contrast, satellites like MODIS and VIIRS provide daily images but with a much coarser spatial resolution (375 meters or more), reducing spatial details. Additionally, there is a lack …

Forests And Cycles Of Agrarian Sustenance: Time-To-Event Analysis Of Ecosystem Provisioning Services And Seasonal Food Insecurity, Kamaldeen Mohammed, Daniel Kpienbaareh

Faculty Publications - Geography, Geology, and the Environment

In Savanna ecosystems, cycles of sustenance include periods of food abundance and deficits. In rain-fed agricultural systems, forests are a vital food source that helps households close this cycle. This paper uses cross-sectional data to explore the association between provisioning ecosystem services and timing to food insecurity in forest fringe communities (N = 500). The time to food insecurity analysis revealed a significant difference in the onset of food insecurity among households with varying levels of access to forest provisioning services. Households with access to more than four forest products experienced a slower timing to seasonal insecurity. In contrast, …

Exploring Ballast Water As A Vector For The Spread Of Stony Coral Tissue Loss Disease, Kathleen Beadling

Masters Theses

Stony Coral Tissue Loss Disease (SCTLD) has led to high mortality rates of reef-building coral species throughout the greater Caribbean region since it was first documented off the coast of Miami in 2014. The pathogen is currently unknown, but it is suspected that ballast water discharge is a vector of disease transmission. As a step towards better understanding SCTLD transmission, this study aimed to identify locations of ballast water exchange that coincide with outbreaks of the disease. Spatial and temporal patterns of SCTLD outbreaks and ballast water exchanges conducted within 50 nautical miles of coastlines were explored using Density-Based Spatial …

Moderating Effect Of Fantasy Football Participation And Location On Team Identification And Nfl Fandom, Devon Hudson

Masters Theses

This study explores how fantasy football participation in varying geographic proximities to NFL teams has altered traditional fan allegiances (i.e. team loyalty or fandom) as an alternate consumer product for the game of football. After utilizing survey data to quantify concepts of fandom and team identification amongst respondents, respondent groups were sorted into various groups based on both fantasy participation and location relevant to NFL teams. A series of hypotheses describing relationships between proximity, fantasy football participation, and fan perceptions are analyzed using a series of statistical tests. No statistical significance was found when comparing strength of team identification amongst …

Bridging Climatology And Energy: Understanding Michigan’S Wind Speeds For A Sustainable Future, Carson Evans

Masters Theses

This study investigates Michigan wind speeds by combining climatology with wind energy, identifying wind drivers and applying them to wind farm infrastructure. Using eXtreme Gradient BOOSTing (XGBoost), this thesis develops a highly accurate predictive model for wind speeds. Coupled with Shapley Additive exPlanations (SHAP) analysis, it is found that proximity to the nearest Great Lake is the ultimate influencer of wind speeds, followed by local environmental variables and finally remote climate phenomena. Other analyses find wind speeds are greatest near the Great Lakes and during fall and winter, while inland summer wind speeds were lowest. Wind energy infrastructure is assessed …

By sketching 200 traditional female dresses from every sovereign country in the world, I have taken the time to analyze and create depictions of their sociological and stylistic choices. I have chosen to examine the countries of Cambodia, Republic of Congo, Croatia, Cuba, Finland, Iran, Kazakhstan, Mongolia, Panama, and Tonga as they all represent different regions of the globe. Breaking down each of their dresses into their specific garments and accessories is essential to better understand the culture and the …

The Insurgent Smart City: How A Social Movement Created An Alternative Imaginary Of The Smart City, Andrew Stokols

Research Collection College of Integrative Studies

Urban scholars have critiqued smart cities for their association with neoliberal governance, narrow focus on quantifiable aspects of urban systems, and failure to incorporate citizens’ needs or aspirations. The “smart city” remains a contested concept and as such is subject to reappropriation. Here, I analyze the case of an urban social movement, the 2019–2020 Hong Kong Anti-ELAB protests, as an alternative, “insurgent smart city.” Following from an earlier network analysis of Telegram channels used during the protests, I show how the communications system underpinning much of the protest action simultaneously enabled coordination while also remaining open to grassroots decision-making and …

Study Of The Extension Of Cavities In Jebel Hafeet By Implementing Geophysical Methods, Mai Rashed Alkaabi

Theses

Subsurface cavities pose challenges to the buildings and their stability, leading to ground instability and subsidence. In Al Ain City, UAE, particularly in Jebel Hafeet, cavities within carbonate formations and sedimentary rocks present risks to infrastructure and urban development. This study employs Electrical Resistivity Tomography (ERT) and Gravity Surveys to detect, locate, and determine the depth of these cavities, enhancing geological understanding and geohazard assessment. The ERT survey, using a pole-dipole array, was conducted along eight lines to identify subsurface anomalies. It revealed high-resistivity anomalies (> 45 Ω·m), indicative of air-filled cavities, and low-resistivity zones (< 6 Ω·m), corresponding to water-saturated or clay-rich deposits. The ERT survey detected resistivity variations, highlighting anomalies ranging from 45 to 120 Ω·m at depths between 1 m and 17 m. The gravity survey, conducted at 28 stations, detected low-density anomalies, which aligned with high-resistivity ERT zones, confirming subsurface cavities at depths between 10 m and 220 m (below ground level). Five 3D gravity inversion models visualized density variations, revealing cavities at different depths for the models from 0 m to 195 m (a.s.l). The integration of ERT and gravity methods significantly improved cavity detection accuracy, demonstrating a strong correlation between low-density gravity anomalies and high-resistivity features. This study recommends increasing gravity station density, and avoiding heavy infrastructure in cavity-prone areas. The findings contribute to the geological understanding of Jebel Hafeet, providing insights for sustainable urban planning, risk mitigation, and infrastructure safety in Al Ain City.
