Sorokdo: From The Island Of Stigma To The Island Of Historical Reflection, Eun-Hye Choung, Hyun-Jin Cho, Jewon Ryu, Suh-Hee Choi

International Journal of Geospatial and Environmental Research

This article focuses on Sorokdo Island (Jeollanam-do, South Korea) as a remnant of the stigmatized landscape reflecting Hansen’s Disease and the Japanese colonial power. Sorokdo began to be stigmatized due to the Japanese colonial rule in the early 20th century when patients with Hansen's Disease were forced to relocate there, suffering from human rights violations and labor exploitation. Isolation and the management of the patients by suppression and control were justified with the logic of modern values of sanitization supported by the colonial rule. Stigma has remained even after the liberation from the colonial power. Continuously recognized by people as …

Exploring The Spatial Distribution Of Air Pollutants And Covid-19 Death Rate: A Case Study For Los Angeles County, California, Akhil Mandalapu, Junfeng Jiao, Amin Azimian

International Journal of Geospatial and Environmental Research

Objective

Since March 2020, COVID-19 has rapidly spread across the world with over 240 million cases and over 5 million deaths as of November 2021. It has been unclear what role air pollutants may play in exacerbating respiratory illnesses such as COVID-19 due to their interaction with the respiratory system. The association with air pollutants and COVID-19 severity has been explored at the regional and metropolitan area, however it is unclear if such an association is consistent at the neighborhood level.

Methods

Weekly death rates from COVID-19 from March 2020 to November 2021 were compared using one-sided unpaired t-tests across …

bySusan Borchardt The University of Wisconsin-Milwaukee, 2022 Under the Supervision of Professor Woonsup Choi

In Wisconsin, the number of high-capacity wells has increased substantially, and concerns have been raised about their impact on both groundwater levels and streamflow. At the same time Wisconsin’s climate has been changing, and both the annual precipitation (5%) and temperature (1.5oC) have been trending upward over the last 68 years and both are predicted to increase into the future. This study attempted to demonstrate the simultaneous effects …

From Orthodoxy To Enlightenment: Discourse, Territory, And Settler Colonialism In Siberia, 1670-1740, Jonathan Noah Adsit

Theses and Dissertations

Though many scholars argue that settler colonialism did not firmly come into practice until the late 18th century in Russia, through an analysis of both 17th century historical chronicle narratives and 18th century explorer accounts, I argue that settler colonial discourses and knowledges are already present, laying the groundwork for later settler practices. In the 17th century, chronicle narratives portrayed Siberian territory as a darkened wasteland turned radiant paradise by the presence of Russian Christians and the expulsion of indigenous non-Christians. In the 18th century, discourse changed to produce the increasing view of Siberia as an object of knowledge, great …

Effects Of Climate, Basin Characteristics, And High-Capacity Wells On Baseflow In The State Of Wisconsin, United States, Susan A. Borchardt, Woonsup Choi, Jinmu Choi

Geography Faculty Articles

When it comes to water resources management, it is critical to understand the factors that affect baseflow processes. Declines in baseflow due to increased use of the groundwater from unconfined aquifers is well documented, but that is not the case for confined aquifers. Furthermore, since the groundwater basin size and shape can be different than the surface water basin, the use of the surface basin to determine well withdrawal rates can affect baseflow and be problematic. This study used the variables determined to be related to baseflow variability (precipitation, temperature, drainage class, available storage, land use, and slope) and the …

Commercial activities within a city have competed to attract people, and the interactions between these activities have affected urban dynamics. Among many services, the restaurant business accounts for a significant portion of the urban economy, with spatiotemporal variations in survivability reflecting crucial signs of changes in urban structure. This study aims to identify the patterns of spatiotemporal changes in restaurants locations to deepen our understanding of urban dynamics. Studies have utilized a variety of data sources, including social media and consumer review services, but they cover relatively short periods and focus on currently operating businesses. Public open data, however, offers …

Characterizing Clustering Models Of High-Dimensional Remotely Sensed Data Using Subsampled Field-Subfield Spatial Cross-Validated Random Forests, Andrew B. Whetten

International Journal of Geospatial and Environmental Research

Clustering models are regularly used to construct meaningful groups of observations within complex datasets, and they are an exceptional tool for spatial exploratory analysis. The clusters detected in a recent spatio-temporal cluster analysis of leaf area index (LAI) in the Columbia River Basin (CRB) require further investigation since they are only derived using a single greenness metric. It is of great interest to further understand how greening indices can be used to determine separation of sites across an array of remotely sensed environmental attributes. In this prior work, there are highly localized minority clusters that were detected to be most …

Strong Trait Correlation And Phylogenetic Signal In North American Ground Beetle (Carabidae) Morphology, Jacob D. Stachewicz, Nicholas M. Fountain-Jones, Austin Koontz, Hillary Woolf, William D. Pearse, Amanda S. Gallinat

Geography Faculty Articles

Functional traits mediate species’ responses to, and roles within, their environment and are constrained by evolutionary history. While we have a strong understanding of trait evolution for macrotaxa such as birds and mammals, our understanding of invertebrates is comparatively limited. Here, we address this gap in North American beetles with a sample of ground beetles (Carabidae), leveraging a large-scale collection and digitization effort by the National Ecological Observatory Network (NEON). For 154 ground beetle species, we measured seven morphological traits, which we placed into a recently developed effect–response framework that characterizes traits by how they predict species’ effects on their …

Flooding is a serious form of natural hazard in Alaska, USA. Two of Alaska’s biggest cities, Anchorage and Fairbanks, have experienced flooding of varying magnitude since the cities were first settled in the early 20th century. Although flood mitigation measures such as blue-green infrastructure (BGI) are rising in prominence, the spatial relationship of BGI, urban pluvial flood (UPF) zone, and social vulnerability remains understudied. This study delineates the UPF zone of Anchorage and Fairbanks using the Blue Spot modeling and correlates it with the distribution of BGI at Census Block Group (CBG) scale, focusing on underlying social vulnerability using a …

Measuring Spatio-Temporal Responses To Hurricane Matthew Employing Twitgis, Seungil Yum

International Journal of Geospatial and Environmental Research

This study explores spatio-temporal responses to Hurricane Matthew across the US states by analyzing Twitter data. This study finds that people in different states and periods respond differently to Hurricane Matthew. For instance, people in the Midwest and Northeast regions show a high proportion of tweets in the pre-hurricane period. Those in the Southeast region demonstrate a high proportion of those in the hurricane period, and those in the West region show a high proportion of those in the post-hurricane period. This study also finds that people increase long distance trips (over 100 km) and decrease short distance trips (within …

Vulnerability And Resilience Of People And Places To Hurricane Damage In The Us. Gulf And Atlantic Coasts From 1950 To 2018, Gainbi Park

Theses and Dissertations

Extreme weather events are expected to increase as a consequence of climate change, increasing the intensity and frequency of natural hazards. Their catastrophic impact is attributable to both the geophysical characteristics of a hazardous event itself and the socio-demographic characteristics of people who are at a greater risk of harm in the aftermath of natural hazards. Previous studies have largely used a place-based approach, measuring the relative level of social vulnerability between places using a social vulnerability index (SoVI), a prevalent spatially explicit method in geographic scholarship. As a composite index, SoVI, has been criticized by scholars due to its …
