Patterns, Drivers, And Implications Of Postfire Delayed Tree Mortality In Temperate Conifer Forests Of The Western United States, Sebastian Busby, Cody Evers, Andrés Holz

Geography Faculty Publications and Presentations

Conifer forest resilience may be threatened by increasing wildfire activity and compound disturbances in western North America. Fire refugia enhance forest resilience, yet may decline over time due to delayed mortality—a process that remains poorly understood at landscape and regional scales. To address this uncertainty, we used high-resolution satellite imagery (5-m pixel) to map and quantify delayed mortality of conifer tree cover between 1 and 5 years postfire, across 30 large wildfires that burned within three montane ecoregions in the western United States. We used statistical models to explore the influence of burn severity, topography, soils, and climate moisture deficit …

Economically Affordable And Ecologically Sustainable Oil Spill Treatments: Review Of Recent Literature, Yue Fan, Jeanne Sumrall

SACAD: Scholarly Activities

Devastating impacts on organisms and the environment are brought by marine oil spills.

Superhydrophobic foams, sponges, aerogels, and biomass materials have been used as absorbents for oil spill treatment.  Among all, Polydimethylsiloxane multi-walled carbon nanotubes Polyaniline Polypropylene felt (Referred to as p-CNT/PANI@PP felt in the following parts) exhibits high absorption selectivity and capability, along with the ability to conduct in harsh environments and the ability to make use of solar/Joule-heating in absorbing a wide span of oil types with high viscosity.

Thus, p-CNT/PANI@PP should be considered as a potentially effective way to address the problem of marine oil spills.

Positioning Disability In Wilderness Space, Rebecca Hobart

Geography ETDs

This thesis examines the social construction of the disabled body in recreational wilderness space. A political ecology framework guides the research questions: What are the actual or perceived barriers to participation for differently abled hikers in wilderness recreational spaces, and how do these challenges manifest in long-distance hiking spaces? In situating Foucault’s theories of the body as shaped by power relations, this thesis asserts wilderness spaces to be privileged based on power conceptualized in normative notions of ability. 44 participants who self-identified as wilderness recreationalists with a disability and/or chronic health illness completed this study’s mixed-method questionnaire. Themes around practices, …

Spatial Behavior Of Hospital Visits By Hand, Foot, And Mouth Disease Patients In Nanchang, China, Zeliu Zheng

LSU Doctoral Dissertations

Hand foot mouth disease (HFMD) is one of the widespread transmissible diseases that target preschool children, especially in urban regions in East Asia. Understanding the travel patterns of the HFMD patients helps us understand how the spatial behaviors of patients vary across space and what are the underlying forces. It is essential for understanding the healthcare market and planning for resource allocation. Foremost, health behavior and outcome change significantly across geographic regions of various urbanicities (i.e., degrees of urbanization) due to the uneven distribution of healthcare resource. In addition, health studies in the U.S. often use hospital service areas (HSAs) …

Platform Urbanism And “Splintering Amenitization”: An Analysis Of Canadian Cities, Anirudh Govind, Agnieszka Leszczynski, Ate Poorthuis

Geography & Environment Publications

This article engages with the spatialities of platform urbanism by foregrounding where digital platforms are located in cities. Drawing on a geocoded data set of visible, material traces of platformization collected across neighborhoods in Toronto, Vancouver, and Montreal, we consider the influences that characteristics of urban built environments—including existing amenities, urban morphology, and area-level socioeconomic factors—have on platforms’ locations. Through a Poisson regression of these variables, we find that the presence of existing urban amenities most strongly explains the locations of material traces of urban platformization on the cityscape at the city block scale. We position platforms themselves as a …

Nowcasting Heavy Rainfall With Convolutional Long Short-Term Memory Networks: A Pixelwise Modeling Approach, Yi Victor Wang, Seung Hee Kim, Geunsu Lyu, Choeng-Lyong Lee, Soorok Ryu, Gyuwon Lee, Ki-Hong Min, Menas C. Kafatos

Institute for ECHO Articles and Research

The recent decades have seen an increasing academic interest in leveraging machine learning approaches to nowcast, or forecast in a highly short-term manner, precipitation at a high resolution, given the limitations of the traditional numerical weather prediction models on this task. To capture the spatiotemporal associations of data on input variables, a deep learning (DL) architecture with the combination of a convolutional neural network and a recurrent neural network can be an ideal design for nowcasting rainfall. In this study, a long short-term memory (LSTM) modeling structure is proposed with convolutional operations on input variables. To resolve the issue of …

Depicting Racial Residential Segregation: An Empirical Analysis Of A Geographical Racial Project In Kent County, Michigan, 2000-2020, Deanna Hughes

Masters Theses

Racial residential segregation has been the foundation for social inequality in American society for many years with links back to slavery and Jim Crow segregation. Many different techniques have been created to study racial residential segregation, with a vast majority of the statistical calculations showing that segregation has been steadily decreasing since the 1960s, sometimes in large amounts. This study seeks to assess these claims by utilizing the same calculations used in those studies and producing dasymetric maps to depict how racial residential segregation is appearing in Kent County, Michigan including Grand Rapids and East Grand Rapids. The following calculations …

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

Agricultural drought occurs in various irrigation areas in Indonesia, one of which is the Jatiluhur Reservoir’s irrigation area. Agricultural drought in this area occurs due to several factors, including the natural phenomenon of climate anomalies which causes the length of the dry season, and also due to less optimal irrigation networks, damaged networks and other obstacles. But, not all agricultural land in the irrigated area experiences drought. Agricultural land affected by drought is important to know its spatial and temporal distribution to determine priority locations in drought disaster management, especially on agricultural land. Therefore, this study aims to examine the …

Does El Niño Affect Mjo-Ar Connections Over The North Pacific And Associated North American Precipitation?, Laís G. Fernandes, Paul Loikith

Geography Faculty Publications and Presentations

This study investigates how the El Niño phase (EN) of the El Niño-Southern Oscillation (ENSO) influences the Madden-Julian Oscillation (MJO) modulation of cool-season North Pacific atmospheric rivers (ARs) and associated AR-landfall North American precipitation between 1980 and 2020. EN changes the key drivers of MJO-AR connections by shifting MJO-driven convection east of 180° in MJO phases 6–8 and extending the northern Pacific subtropical jet eastward. Under these conditions, the MJO tropical-extratropical teleconnection is triggered east of 180° in phases 7–8, and a persistent cyclonic flow anomaly develops along the United States west coast. Anomalous northeastward integrated water vapor transport (IVT) …
