Prehistoric Origins Of The Chippewa Indians, Ronald A. Janke Apr 2025

Prehistoric Origins Of The Chippewa Indians, Ronald A. Janke

The Geographical Bulletin

This paper investigates the location of precontact Chippewa contacts and the complexities of the geographic environment in which they occurred. Reconstructed land use and settlement maps along with recent archaeological and linguistic research have added new ideas concerning the origin, early migrations, and contacts of the Chippewa Indians. Very little is known about the culture and the area that the Chippewa occupied before the time of European influence. According to the legends and traditions of the Chippewa, they originally inhabited the area next to the Gulf of the St. Lawrence River, near the Atlantic Ocean, and gradually moved westward and …

The Impact Of A Growth Center On An Agricultural Hinterland: A Case Study Of Taegu, Korea, Soohyun Chon Apr 2025

The Impact Of A Growth Center On An Agricultural Hinterland: A Case Study Of Taegu, Korea, Soohyun Chon

The Geographical Bulletin

Although the location of large urban centers such as Seoul, Pusan, and Taegu has had a major impact on changes in the surrounding agricultural hinterland, regional differences of agricultural development in Korea have not received much attention until recently (Fig. 1). Keidel, for example, noted that Kyongi-do and Kyongsangnam-do have higher agricultural income levels than the remainder of the country because they produce commercial crops for Seoul and Pusan, respectively.1 More recently, after the construction of a modern highway between these two cities, Chungchongbuk-do and Kyongsangbuk-do provinces emerged as the major suppliers of commercial crops for Seoul and Pusan.

An Evaluation Of Planned Settlement In The Bolivian Tropics: The 1974 Plans, Martha A. Works Apr 2025

An Evaluation Of Planned Settlement In The Bolivian Tropics: The 1974 Plans, Martha A. Works

The Geographical Bulletin

In the early 1960's Bolivia made the first set of attempts at colonization of the lowlands, or Oriente, lying east of the Andes. This effort was largely in response to events that had taken place earlier in the century, namely the Chaco War, the Social Revolution of 1952 and the collapse of the mining economy.1 Colonization schemes were implemented in an attempt to provide enough land for the people, increase opportunities for displaced miners, and to promote national unity by settling the eastern areas of the nation.2 The early colonization projects were concentrated in two areas -the Alto Beni (east …

Bending Traditions To Avoid Breaking The Rulesthe Arthur, Illinois Amish, Page Redmond Apr 2025

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 …

Suburban Land-Use Policies And. Community Pressure Groups In Southfield, Michigan, Joseph H. Kogelmann Apr 2025

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 …

Crucible Of Excellence: The Honor Society, O. Orland Maxfield Apr 2025

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. …

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 …

Bridging Climatology And Energy: Understanding Michigan’S Wind Speeds For A Sustainable Future, Carson Evans Apr 2025

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 …

Suspended Agency And The Habitus Of Waiting In A Migrant Shelter In Tijuana, Liam K. Ogden Iii Apr 2025

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 …

Enhancing Remote Sensing Imagery Temporal Resolution Using Starfm Data Fusion Approach For Improved Land Surface Monitoring, Ahmadreza Pourghodrat Apr 2025

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 …

Study Of The Extension Of Cavities In Jebel Hafeet By Implementing Geophysical Methods, Mai Rashed Alkaabi Apr 2025

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.
