Conceptual And Technological Advancements In Visitor Use Management Of Coastal And Estuarine Environments, Tyler Cribbs

All Dissertations

This dissertation demonstrates the exploration and use of conceptual and technological advancements in the science of visitor use management (VUM). The goal of this effort is to help better understand visitors to park and protected areas (PPAs) and more specifically, better manage our coastal and estuarine environments (i.e., coastal protected areas (CPAs). These concepts and techniques are 1) further implementing the use of cellphone data in recreation ecology and VUM, 2) assessing the use of advanced imagery, virtual reality (VR), in visual-based methods to determine visitor indicators and thresholds, and 3) assessing visitor’s awareness of PPAs and how it influences …

The Dynamic Nature Of Wrack: An Investigation Into Wrack Movement And Impacts On Coastal Marshes Using Suas, Grayson R. Morgan, Daniel R. Morgan, Cuizhen Wang, Michael E. Hodgson, Steven R. Schill

Faculty Publications

This study investigates the use of small unoccupied aerial systems (sUAS) as a new remote sensing tool to identify and track the spatial distribution of wrack on coastal tidal marsh systems. We used sUAS to map the wrack movement in a Spartina alterniflora-dominated salt marsh monthly for one year including before and after Hurricane Isaias that brought strong winds, rain, and storm surge to the area of interest in August 2020. Flight parameters for each data collection mission were held constant including collection only during low tide. Wrack was visually identified and digitized in a GIS using every mission orthomosaic …

Projecting Vegetation Condition And Fire Risk In Southern California, Westin K. Guthrie

Geography ETDs

In the western US, relationships between fire, vegetation, climate, and urban areas are dynamic and evolving. This work used a forest landscape model, LANDIS-II, informed by future climate scenarios and projections of urban expansion to understand wildfire interactions within projected Wildland Urban Interface (WUI) areas. This simulation showed that in both 2050 and 2100 +93% of the WUI in southern California experienced fire. Future work needs to be done in parametrizing forest biomass to ensure the validity of projections. Additionally, increasing each climate scenario model's replicates will create more accurate projections.

Urban Sustainability Implementation And Indicators In The United States: A Systematic Review, Heejun Chang, Arun Pallathadka, Idowu Ajibade

Geography Faculty Publications and Presentations

Urban sustainability is the goal of many cities in the world, yet very few have achieved a level of sustainability that goes beyond the most basic environmental objectives. The practice and assessment of sustainability implementation are greatly compounded by lack of funding, technical know-how, political will, and the power disparity between dominant institutions and marginalized communities. This systematic analysis of urban sustainability literature involved the review of 241 studies published between 2010 and 2022. We critically examined current debates and challenges in urban sustainability, identifying gaps and opportunities and providing recommendations for creating equitable, just, and sustainable urban futures. We …

Spatial Analysis Of Streamflow Trends In Burned Watersheds Across The Western Contiguous United States, Heejun Chang, Will B. Long

Geography Faculty Publications and Presentations

Despite increasing magnitude and frequency of wildfire, understanding hydrological processes contributing to changes in streamflow is not well examined for the entire western contiguous United States (WCONUS). This study provides insight into whether considering spatially varying watershed characteristics, including burn severity patterns, can better explain streamflow trends at broad spatial and temporal scales. Standard geographically weighted regression (GWR) and multi-scalar (MS) GWR were benchmarked against ordinary least squares (OLS) regression to determine if spatially varying coefficients could better explain spatially varying patterns and processes of peak flow, low flow, center timing of flow, and flashiness trends in burned watersheds. In …

Quantifying Damages To Soil Health And Emissions From Land Development In The State Of Illinois (Usa), Elena A. Mikhailova, Hamdi A. Zurqani, Zhenbang Hao, Mark A. Schlautman, Gregory C. Post, George B. Shepherd, Christopher C. Post, Renee M. Dixon

Geography Faculty Publications and Presentations

The concept of soil health is increasingly being used as an indicator for sustainable soil management and even includes legislative actions. Current applications of soil health often lack geospatial and monetary analyses of damages (e.g., land development), which can degrade soil health through loss of carbon (C) and productive soils. This study aims to evaluate the damages to soil health (e.g., soil C, the primary soil health indicator) attributed to land developments within the state of Illinois (IL) in the United States of America (USA). All land developments in IL can be associated with damages to soil health, with 13,361.0 …

A Comparative Study Of Vinti-Based Orbit Propagation And Estimation For Cubesats In Very Low Earth Orbits, Ethan Michael Senecal

Mechanical & Aerospace Engineering Theses & Dissertations

In recent years, there has been a growing interest in CubeSats and very low Earth orbit (VLEO) space missions. Mission SeaLion, a collaborative CubeSat mission between Old Dominion University, the U.S. Coast Guard Academy, and U.S. Air Force Institute of Technology, planned to launch a 3U CubeSat into VLEO. The VLEO mission is a particularly challenging environment for navigation and orbit propagation because drag introduces a significant perturbation for orbit models such as SGP4. Additionally, mission requirements left no capacity for attitude determination or control, further reducing knowledge of drag behavior of the satellite in flight. This deficiency is a …

Bruno Latour's Constructivism And Its Implications For The New Agency Of Sociology, Robertus Robet, U. Abdul Rozak R

Masyarakat: Jurnal Sosiologi

Abstract

Latour removes the boundaries between natural sciences and humanities. Science for Latour is cultural practise, at the same time in every cultural practice, nature and objects are also actively involved. In that sense, Latour's constructivism encourages the emergence of non-human actors as drivers of the societal changes. By that, he provoked sociology to expand its subject matter. The Social in sociology must be seen as an association involving human and non-human actors.

Key words: Constructivism, Expansion of agency, actant, actor network theory.

A Constructivist Analysis Of China’S Geopolitical Economic Strategy Toward Africa: A Case Of Sino-Tanzanian South-South Cooperation, Azza Bimantara

Global: Jurnal Politik Internasional

This article discusses China’s foreign policy toward African countries by examining Sino-Tanzanian South-South Cooperation (SSC). By utilising a modified, state-centric social constructivism, this study identifies domestic and international realms of China’s normative structure responsible for shaping China’s identities within the international community. It also explains how China can reconcile its competing identities between a Global South and rising great power statuses, which gives China the ability to combine its normative interest (i.e., Global South solidarity) and material interest (i.e., the geopolitical-geoeconomic strategy) into a diverse project of SSC with positive and proactive perception from Tanzania. This study contributes toward the …

The Impact Of Climate Change On Selected Pnw Watersheds Through The Lens Of Western Red Cedar Habitat, Jordan T. Hamann

Dissertations and Theses

Climate change is a real phenomenon that is exacerbating existing natural processes and developing into a new normal for the planet. This change may be devastating for Pacific Northwest populations of Western Red Cedar (WRC) west of the Cascade Mountain range in the states of Oregon and Washington. WRC is a valuable tree species for reasons both economic and cultural. Dieback among WRC is following an accelerating trend. Since dieback is usually followed by tree mortality, understanding its causes and distribution is beneficial to the overall success of the species going into the future.

No. 12: Rural-Urban Transition And Food Security In India, Chetan Choithani, Abdul Jaleel Cp, S Irudaya Rajan

Migration and Food Security (MiFOOD) Network

As a growing proportion of world’s population lives in cities and towns, food security is increasingly acquiring an urban character. The locus of food security research and policy agendas has correspondingly expanded from rural areas to include cities and towns in the past few years. However, the dominant discourse on urbanization-food security relationship appears to be shaped by perspectives from the Global North and large cities, and shows a lack of adequate understanding of the urbanization-food security nexus in the small towns of the Global South. This paper aims to correct this bias. With a focus on India where urban …

State Of Urbanization In Nepal: The Official Definition And Reality, Keshav Bhattarai, Ambika P. Adhikari, Shiva Gautam

Himalayan Research Papers Archive

Nepali government’s official delineation of several human settlements as new urban areas has been questionable because many important criteria such as urban infrastructure and services, open space, population density and economic viability are not thoroughly analyzed while defining what is urban. Many settlements in Nepal officially defined as urban, often driven by political considerations, are operating in the rural framework forming ruralopolises. This paper analyzes various criteria needed for defining urbanization that are internationally accepted to assess Nepal’s official definition of urban settlements. Urban areas have been expanding in Nepal at the cost of agricultural, forest, and shrubland land uses. …

The Relationship Between Water Temperature And Proximity To Surface Urban Heat Islands Within The Lower Chesapeake Bay Watershed For The Summer Of 2019, Sarah Kerner

Departmental Honors & Graduate Capstone Projects

Surface urban heat islands (SUHIs) are land surfaces with high concentrations of impervious surfaces like roofs, roads, sidewalks and other infrastructures that trap, absorb, and re-emit heat throughout the day/night and typically present higher temperatures than their surrounding rural areas. In this study, I evaluate how presence of and distance to SUHIs are associated with water temperature in the lower Chesapeake Bay watershed for the summer of 2019. When heavy precipitation events occur, flooding creates stormwater runoff, which is exposed to the hotter temperatures in urban areas. This introduces thermal pollution to nearby rivers and streams disrupting aquatic ecosystems. The …

The Bearing Earth: Colonization, Conservation, And Political Ecology In Costa Rica (Coto Brus 1948 - Present), Pablo Alonso Arias-Benavides

Latin American Studies ETDs

This thesis presents two questions: How are relationships between people in Coto Brus and the land – specifically, forest – mediated by social, political, and economic forces? How are personal and collective identities expressed through relationship with the landscape? I chose Coto Brus because it is a forested region of Costa Rica which was populated with state support in the 1950s, and because it is my father’s hometown. In order to understand the subjective experiences of Costa Ricans involved in deforestation and reforestation, I performed interviews in the canton, visited conservation sites, and analyzed historical sources. This study combines multiscale …
