Cartographic Analysis Of Earth-Sun Relationships In Ancient Amazonia, Jackson Bennett Critser 2023 University of Arkansas, Fayetteville

Cartographic Analysis Of Earth-Sun Relationships In Ancient Amazonia, Jackson Bennett Critser

Graduate Theses and Dissertations

The alignments of ancient man-made earthworks across the Amazon Basin, known as geoglyphs, have recently been discovered to predate early societal dates. Although much research indicated that the Amazon was uninhabitable until the last 1000 years (Meggers 1971), new evidence suggests this is not the case. The application of advanced cartographic and GIS technologies were implemented to link solar ‘marker’ days (e.g. solstices, equinoxes) with the alignment of geoglyphs, megaliths, stone architecture, and broader city forms to discover and analyze previously unknown Earth-Sun relationships across the Amazon Basin to conceivably sophisticated urban and architectural plans. The study of these geoglyphs …


The Terroir Of Swiss Cheese: A Temporal And Geomorphological Investigation Of The Martian Co2 Sublimation Pits, Racine D. Cleveland 2023 University of Arkansas, Fayetteville

The Terroir Of Swiss Cheese: A Temporal And Geomorphological Investigation Of The Martian Co2 Sublimation Pits, Racine D. Cleveland

Graduate Theses and Dissertations

Observations by NASA Mars Global Surveyor showed evidence of rough topography on the South Pole of Mars. The topography is the result of CO2 sublimation processes that occur through the changing seasons on the red planet. These sublimation areas are known to scientists as Swiss Cheese Features (SCF). SCF are erosional degradation pits that have been studied for over two decades. Studies show that these SCF increase in area over time, but these values are collected by hand on a per feature basis. Models for the pit evolution have also played a part in understanding these SCF. This work is …


The Manito Topos Project: Place Naming And Toponymic Silencing In The Sierras Of Northern Nuevo México And Southern Colorado, Len N. Beké 2023 University of New Mexico

The Manito Topos Project: Place Naming And Toponymic Silencing In The Sierras Of Northern Nuevo México And Southern Colorado, Len N. Beké

Spanish and Portuguese ETDs

This dissertation reports on documentary research on vernacular toponymies in Manito communities in Nuevo México and Colorado. These toponymies are erased, obscured and delegitimized in official maps. Within the study area, vernacular antecedents for 49.5% of official names for natural features were documented, along with 280 previously unmapped names. These data were compared to the state-sanctioned toponymy to determine a typology of linguistic mechanisms of toponymic silencing. While a majority of official toponyms are based on Manito oral tradition, only 15.4% of the labels for natural features represent unaltered versions of names in that tradition. This dissertation theorizes the conceptual …

Modeling The Impacts Of Sea Level Rise In Coastal Virginia At Multiple Scales, George Murray Mcleod Iv

OES Theses and Dissertations

Relative sea level is increasing along the Mid-Atlantic coast of the United States and the rate of relative sea level rise (ΔRSL) for Coastal Virginia is approximately double the rate of global sea level rise (ΔSLRG)(1). The potential impacts posed to communities by ΔRSL are best understood by examining the spatial relationship between the upper limits of ocean-connected waters and the geographic positioning of critical natural and societal assets. This research examines this problem at three spatial scales to quantify the impacts of ΔRSL and storm flooding events on (i) structural and transportation infrastructure for the tide-influenced coastal zone of …

A Stable Isotopic Profile Of Atmospheric River Precipitation Impacting Northern California, Erika Clarise Ornouski

LSU Master's Theses

Atmospheric river (AR) storms are an integral part of California’s hydrologic cycle, providing 30–50% of the state’s annual precipitation. However, “too much of a good thing” can swell

rivers beyond capacity leading to widespread flooding, erosion, and environmental damage. Northern California’s steep topography coupled with its seasonal Sierra Nevada snowpack puts this region at risk for floods and extreme weather hazards that can be triggered by strong ARs. Identifying AR contributions in the water cycle is crucial for informing water resource and emergency management decisions Stable isotope analysis provides a means to understand the movement of precipitation based on fractionation …


China's Public Diplomacy Philosophy, Logan Webb 2023 Arkansas Tech University

China's Public Diplomacy Philosophy, Logan Webb

ATU Scholars Symposium

China has become a giant in the globalized world in such a short period of time. This led me to the research question, “What is China’s public diplomacy philosophy?” Using a textual analysis of major geopolitical events that China is involved in (The Belt and Road Initiative, the South China Sea dispute, Uyghur imprisonment, and the Hong Kong government takeover) and the history of China since the Chinese Civil War, it becomes apparent that the country uses the concept of hard and soft power for its public diplomacy. If a country is not receptive to China or its intended actions, …

Community Resilience: Conducting A Tornado Risk Assessment For Oklahoma City, Oklahoma​, Chanice Brown 2023 Kennesaw State University

Community Resilience: Conducting A Tornado Risk Assessment For Oklahoma City, Oklahoma​, Chanice Brown

Symposium of Student Scholars

On May 20th, 2013, the Newcastle-Moore tornado carved a 14-mile-long path of destruction through Oklahoma City, McClain, and Cleveland Counties. This event led to the deaths of 24 people, more than 200 injuries, and at least 2 billion dollars in damages. Tornadoes like the Newcastle-Moore are sporadic and technological advances have provided an extra layer of protection against them. However, researchers have found that one of the best methods for bolstering the safety of a community when facing such severe weather threats is developing a hazard mitigation plan. As such, the focus of this particular project was to identify the …

No. 08: Young People’S Mobilities, Farming Aspirations And Engagements In Northern Ghana, Siera Vercillo, Bruce Frayne 2023 Wilfrid Laurier University

No. 08: Young People’S Mobilities, Farming Aspirations And Engagements In Northern Ghana, Siera Vercillo, Bruce Frayne

Migration and Food Security (MiFOOD) Network

Development policies targeting young people and African agriculture tend to focus on their abandonment of the sector and the need to attract new generations to agricultural activities through its commercialization. This paper points to potential gaps in such interventions by investigating the diverse mobilities, aspirations, and engagements of young people in farming, through a qualitative case study in rural northern Ghana. Our study also challenges the prevalent assumption of African farmers’ movements from rural to rural areas, from rural to urban areas, and out of farming altogether, as we found evidence of young people migrating from urban to rural areas. …
