Graduate Student Theses, Dissertations, & Professional Papers

Hear Me Roar, a compilation of personal essays interspersed with short forms, grapples with the nuances of compliance versus autonomy in the context of the male gaze, beauty standards, and pop culture. The collection also explores what it means to treasure something—another person, an object—and how to express and deepen that affection.

Understanding Native American Hemp Production, Cynthia Marie Steckdaub Coleman

Graduate Student Theses, Dissertations, & Professional Papers

In this thesis, I take an in-depth look at Native American hemp production through the lens of three hemp projects. My research sits within the history of colonization and dispossession. I look at two tribal hemp projects and one individual Native American hemp farm and describe how each project reaches for tribal sovereignty through hemp production. I look at how hemp fits into tribal worldviews, cultures, and the relationship tribal farmers have with hemp. Focusing on key elements of relationship, like respect, reciprocity, and responsibility, I examine how hemp production can be incorporated into Indigenous communities. Beyond relationships with the …

Habitat Use And Prey Selection By Mountain Lions In An Altered Sagebrush Steppe Environment, Jonathan Ewanyk

Cal Poly Humboldt theses and projects

Throughout the American West there is an increasing trend of encroachment of woody vegetation on previously open sagebrush steppe habitat. The Modoc Plateau in northeastern California has not been excluded from this encroachment trend and has seen an increase in western juniper (Juniperus occidentalis) densities, likely as a result of long-term fire suppression. Mountain lions (Puma concolor) have not previously been studied on the Modoc Plateau, and there is potential for an increase in cover due to juniper encroachment to benefit the hunting behavior of lions. To better understand if the presence of cover is being …

Resilience, Capacity, And Place: A Comparative Case Study Of Small-Scale Forest-Based Biomass Energy Development In California’S Sierra Nevada Mountain Range Communities, Rebecca E. Cashero

Cal Poly Humboldt theses and projects

The buildup of fuels resulting from decades of fire suppression in California's Sierra Nevada mountains has made its dense forests vulnerable to high severity stand replacing wildfires. Local governments in many rural forest-dependent communities view biomass energy production as a method to restore forest health via fuel removal and waste disposal. Forest-based biomass energy facilities have the potential to be compatible with protecting water resources, habitat restoration, forest resilience, and achieving climate standards, while also enhancing regional economic stability. However, while an increasing number of communities and organizations throughout California are advocating for local small-scale renewable energy from forest-based woody …

Yes Douglas Husak, Drunk Driving Is A Serious Offense., Brittany Kurland

Harriet L Wilkes Honors College Theses 2010 - 2019

Drunk driving is a serious offense, but often goes unnoticed because no harm is often caused by the person committing such a selfish act. Where there is an accident, fatal or minor, the individual is punished for driving while intoxicated. While many theorists believe that it is inappropriate to punish one who has a blood alcohol concentration (BAC) over the legal limit of .08%, I propose that regardless of the individual harming or not harming another, the person who is driving while intoxicated should face punishment. It should not matter if the driver did not show any signs of impairment …

Latinx/@ Immigrant Inclusion Trajectories: Individual Agency, Structural Constraints, And The Role Of Community-Based Organizations In Immigrant Mobilities., Cirila Estela Vasquez Guzman, Julia Meredith Hess, Norma Casas, Dulce Medina, Margarita Galvis, Diana Anahi Torres, Alexis J. Handal, Annette Carreon-Fuentes, Alexandra Hernandez-Vallant, Mario J. Chavez, Felipe Rodriguez, Jessica R. Goodkind

Pediatrics Research and Scholarship

Immigration is at the forefront of national, state, and local policy struggles in the United States, and Latinx/@ immigrants have experienced increased deportations, detention, and individual threats. A mobilities perspective allows analysis to extend our view of migration beyond frameworks confined to pre- and postmigration, examining trajectories of social inclusion and exclusion that are influenced by multiple factors in the receiving country. The Immigrant Well-being Project, a community-based participatory research project involving university faculty, students, staff, and representatives from 4 community-based organizations (CBOs), was initiated in New Mexico in 2017 to better understand and promote Latinx/@ immigrant mental health and …

Externalities As The Status Quo: Federal Application Of Environmental Charges In The United States, Robert Zupko

Dissertations, Master's Theses and Master's Reports

Conceptualized as early as 1920 by English economist Arthur Cecil Pigou, but not formalized until later work in the 1970s and 1990s, “environmental charges” are a form of Pigouvian taxes that suggest the revenue burden of governance could be shifted from economic “goods” to environmental “bads”. While their association with Pigouvian taxes would suggest that environmental charges are applied as a policy instrument to encourage the reduction or elimination of environmental externalities, their application at the federal level in the United States suggests this is not the case. This report postulates that federally applied environmental charges accept environmental externalities as …

Elephants And Pandemics, Adrian Treves

Animal Sentience

Baker & Winkler’s critique of Asian elephant tourism and conservation in Thailand has convinced me that this was “an industry with too many victims.” Yet I fear that B&W’s proposed remedy of returning to past elephant husbandry by Karen hill-peoples has little likelihood of improving the lives of the elephants for long. Who can predict whether the Karen will live up to this hope? B&W advocate for the Karen, but not for “an abolitionist stance on elephant-human relationships.” In my view, whether we discuss elephants or the wild mammals that carry SARS-CoV-2, abolition of many human uses of animals is …

Rewilding And Mixed-Community Collaboration In Conservation, Liv Baker

Animal Sentience

Rewilding is a psychological and sociocultural event for nonhuman animals that goes beyond the traditional framework of ecology. Elephants need to be seen as political agents in a collaboration. Our commentators shed light on the hierarchical assumptions and politics involved. Mixed-community collaboration can create dynamic and sustainable conservation interventions that are crucial to reconceptualizing the human-elephant relationship beyond the concept of labor. The profound effects of the Covid-19 pandemic have laid bare the fundamental vulnerabilities of the elephant tourism industry. Moreover, how well an elephant has been buffered by the fallout of the pandemic is dependent on the specific relations …

Conventional Science Will Not Do Justice To Nonhuman Interests: A Fresh Approach Is Required, Becca Franks, Christine Webb, Monica Gagliano, Barbara Smuts

Animal Sentience

Treves et al. (2019) make a convincing case that conservation efforts need to go beyond an anthropocentric worldview. Implementing that vision, however, will require human advocates to represent nonhuman interests. Where will the knowledge of those interests come from? How can humans know what is in the best interest of another animal, a plant, or an ecosystem? We discuss how the values embedded in current scientific practices may be ill-suited to representing nonhuman interests and we offer some ideas for correcting these shortcomings.

How To Engage Public Support To Protect Overlooked Species, Scarlett R. Howard, Adrian G. Dyer

Animal Sentience

Treves et al. (2019) propose a non-anthropocentric approach to conservation biology for the ‘just preservation’ of non-humans. Some of our current ways of ranking conservation efforts based on benefits to humans are indeed critically flawed, but we doubt that a completely non-anthropocentric approach is possible at this time. We propose a way to generate public support for those non-human species that may otherwise be overlooked in policy-making and conservation efforts.

Just Preservation, Trusteeship And Multispecies Justice, Francisco J. Santiago-Ávila, Adrian Treves, William Lynn

Animal Sentience

We are grateful to all the commentators who engaged with our target article. Some commentators have offered important insights into our proposed design and methods for legally intervening on behalf of futurity. Others have focused on theoretical considerations central to our proposal for multispecies justice and trusteeship. All have inspired modifications and further elaboration of our initial proposal. In this Response, we engage with the commentaries, integrating their suggestions, striving for convergence and complementarity, but also discussing points of divergence with our proposed framework where necessary. There is substantial overlap in the points of view of the three co-authors, but …

Surface-Enhanced Raman Scattering Using Fluorescence-Quenched Carbon Quantum Dots For Mercury Ion Detection, Andaru Dena Prasiwi

Chulalongkorn University Theses and Dissertations (Chula ETD)

Mercury ion (Hg2+) is one of the most challenging problems due to its high toxicity at low concentration and bioaccumulative effects affecting human health. Herein, we propose a strategy to exploit the fluorescence quenching of carbon quantum dots (CQDs) combined with surface-enhanced Raman scattering (SERS) technique to detect Hg2+. CQDs exhibit strong fluorescence emission interfering SERS measurement. However, with the presence of Hg2+, fluorescence from CQDs can be quenched, and the SERS spectrum can be collected. In this work, SERS spectra of rhodamine 6G (R6G) incorporated with CQDs and Hg2+ (0.100‒100 ng/L) were studied. The SERS spectra of R6G was …

Applied Environmental Research

Examining how seagrass decomposition contributes to trophic pathways in marine ecosystems is crucial in understanding seagrass production. Decomposition rates of seagrasses may depend on many factors such as chemical composition and microbial colonization. In this study, microbial colonization and changes in chemical composition of decomposing material (necromass) of Smooth Ribbon Seagrass, Cymodocea rotundata of Bogtong Bay, Lahuy Island, Caramoan, Philippines were monitored. Seagrass litter were placed in litterbags and incubated in the seagrass meadow in situ for 56 d. Serial dilution, viable plate counts and microbial oxygen consumption analyses were done and gravimetry, Kjeldahl method and acid hydrolysis were used …

Evaluation Of Meskat System Functionality As Water Harvesting At Wadi Hamdoun Watershed (Sousse, Tunisia) Using The Geographic Information System, Asma B. Salem, Soumaia M’Nassri, El A. Asma, Riadh Bouaziz, Rajouene Majdoub

Applied Environmental Research

In the Sahel of Tunisia, areas were characterized by complex landforms like hills and depression with active and alternation of the geographical processes between bare hilly limestones and fertile soils. These landforms consist of the Meskat system. It represents the commonly used micro-catchment of water harvesting for olive tree groves as traditional soil and water conservation technique. However, in recent years, this system seems to be increasinglyneglected. The present study aims to determine the current functionality of the Meskat systemin the watershed of Wadi Hamdoun through the use of a geographic information system (GIS) as well as field's investigation. Results …

Environmental Pollution Of Heavy Metals In A Vietnamese Informal E-Waste Processing Village, Hien Thi Thu Ngo, Li Liang, Diep Bich Nguyen, Hai Ngoc Doan, Pensri Watchalayan

Applied Environmental Research

Inappropriate handlings of informal e-waste processing have increasingly become a global environmental and public health issue of concern. This study was conducted to quantify the concentrations of five heavy metals found in the environmental media at an exposed village and a reference village in Northern Vietnam. The correlations between a pair of the heavy metals found in a medium, and between a pair of the environmental media was found. The results showed that drinking water was safe for heavy metal exposure in both studied villages. However, at the exposed village, the levels of the heavy metals found in indoor soil …

Teak ring-width is one of the promising paleoclimate proxies in the tropical region. Tree-ring chronology spanning from 1840 to 2016 (177 years) was derived from 76trees from Phrae Province, northern Thailand. A total of 141 core samples were cross-dated, a standardized master was constructed, and the tree residual master chronology was developed by ARSTAN program. The tree-ring chronology has a significant positivecorrelation with the monthly rainfall and relative humidity during the monsoon season (May - June). In addition, the growth of tree-ring width also significantly inversely correlated with Niño 3, Niño 3.4, and Niño 4 indices during the second half …

Hydrogen Peroxide: A Grower’S Best Friend?, Mitchell Eicher-Sodo

Theses and Dissertations (Comprehensive)

Hydrogen peroxide (H₂O₂) is an oxidizing agent used to disinfect irrigation systems (e.g. nutrient solution and equipment) used in controlled environment plant production and produces no harmful by-products. The action of H₂O₂ is non-selective, and therefor H₂O₂ will oxidize all components of the irrigation water as well as tissues from the greenhouse crops being irrigated. The phytotoxic effect H₂O₂ has on common greenhouse crops is not well understood, requiring detailed characterization and determination of threshold concentrations. Thresholds within the thesis were based on applied H₂O …

Monitoring Environmental Change Using A Participatory Modified Photovoice Approach With Indigenous Knowledge Holders In Kakisa, Northwest Territories, Kaitlin Kok

Theses and Dissertations (Comprehensive)

In response to growing pressures from climate change and the lack of a monitoring strategy for food security at a local and regional level in the Northwest Territories, there is an urgency for residents to record their own images of change in relation to harvester safety. This thesis explores the connection between geographic information systems, sustainable food systems, indigenous knowledge and the importance of place. The objective of this study is two-fold: (a) to develop a monitoring system in conjunction with the community of Kakisa and (b) to increase the resilience of the local food system. The methods used derive …

Fanm Pa Chita: Mobilities, Intimate Labour, And Political Subjectivities Among Haitian Women On The Move, Masaya Llavaneras Blanco

Theses and Dissertations (Comprehensive)

This dissertation asks: how does intimate labour interact with the mobility and political subjectivities of Haitian migrant women and women of Haitian descent in the Dominican Republic (DR)? It answers this question in three specific ways. First, it explains the relationship between intimate labour and the spatial trajectories of women of Haitian ancestry who work as domestic workers. Second, it examines how the interaction between intimate labour and human mobility plays out in the Dominican border regime. Third, it explains how these subaltern women act politically in the midst of the intersections between borders, mobilities, and intimacy.

The dissertation proposes …

Beyond A Mapping Exercise: Inclusion Of Aboriginal Traditional Ecological Knowledge In Parks And Protected Areas Management, David Cook

Theses and Dissertations (Comprehensive)

This paper examines current approaches for Parks and Protected Areas (PPA) managers in incorporating Aboriginal Traditional and Ecological Knowledge (ATEK) into their management plans. This paper focuses on two case-studies. They are Nahanni National Park and Reserve in the Dehcho region of the Northwest Territories, and the Whitefeather Forest Protected Area in the Pikangikum First Nations Traditional Territory in Ontario. They were chosen because of their unique approaches to include Aboriginal communities in the planning process and their designation as UNESCO World Heritage sites. The broader indigenous involvement policies of both Parks Canada and Ontario Parks are examined using academic …

Seeking A Path To Wellness And Flourishing: Exploring Ecological Citizenship, Systems Thinking, And Environmental Governance In Southwest Yukon, Amanda Solmes

Theses and Dissertations (Comprehensive)

While efforts toward environmental management (EM) have been increasing, the state of our natural world is getting worse. Numerous reports have outlined that today’s environmental problems are predominantly human-induced, yet approaches to EM often only address “environmental” rather than “human” issues. More holistic approaches are required. This thesis explores “ecological citizenship” (EC) as an alternative framework that may have the potential to address elements too often left out of top-down and reductionist approaches. Academic and case-based notions of this concept are explored, and a new definition for the term is developed. A case study, drawn from the rich results of …

Characterizing The Hydrological Function Of Treed Bogs In The Zone Of Discontinuous Permafrost, Brenden Disher

Theses and Dissertations (Comprehensive)

The loss of permafrost has produced a wholesale conversion from forest to wetland, and many studies have analyzed the effects of permafrost thaw-induced land cover change on the hydrology and ecology of landscapes within the Taiga Plains. The permafrost thaw driven areal shrinkage of forested plateaux and their replacement by treeless wetlands is well documented, and the co-occurrence of permafrost and black spruce forest cover is the basis for areal estimates of the former. However, field studies conducted at a peatland dominated landscape near Fort Simpson, NWT indicate that tree canopy may persist following the loss of permafrost and the …

An Evaluation Of Ground-Freezing Methods In The Zone Of Discontinuous Permafrost, Northwest Territories, Elzbieta Mastej Ms

Theses and Dissertations (Comprehensive)

Northwestern Canada is one of the most rapidly warming regions on Earth. The southern limit of the discontinuous permafrost zone is highly sensitive to small climatic fluctuations and presently experiencing a rapid landscape change due to accelerated permafrost thaw, which is further exacerbated by anthropogenic disturbances such as seismic exploration. Recent research has begun to examine both natural and mechanical approaches to minimize permafrost loss, although the utility of such methods in peatland environments is not well understood. This study explored the efficiency of natural and artificial ground cooling processes in a peatland environment by evaluating snow exclusion and thermosyphon …

Projecting Spatial Changes In Sugar Maple Sap Flow Regimes In A Changing Climate, Holly Crawford

Theses and Dissertations (Comprehensive)

Anthropogenic climate change presents a potential threat to maple syrup production in Canada. To mitigate risks associated with climate change, information about the biological changes that may occur in a warming climate are necessary. This project studied one component- sap flow- that in part determines the economic viability of maple syrup production. A temperature-based sap flow model was used to project the start of the sap flow season in southern Ontario, and GIS applications were used to aggregate the results. The start of the sap flow season was projected for early, mid, and late-century periods under two climate change scenarios, …

Impact Of Seismic Lines On The Hydrology Of Wetlands In The Discontinuous Permafrost Zone, Southwestern Northwest Territories, Angela Hamilton

Theses and Dissertations (Comprehensive)

Previous studies in the southern Northwest Territories have shown the underlying discontinuous permafrost is sensitive to disturbances such as the creation of seismic lines. Their creation has resulted in compaction topsoil and tree removal causing accelerated permafrost thaw. The loss of permafrost has caused seismic lines’ surface elevation to subside, which allows water to conjugate. This increases the soil moisture of a seismic line, which results in preferential thaw along the seismic line edges. Thaw along the edges over time has connected more previously isolated wetlands to seismic lines. This leads to more water entering, resulting in higher water levels …

Reconstructing Hydrologic Conditions And Metals Supplied By The Peace River To The Peace-Athabasca Delta, Jelle André Faber

Theses and Dissertations (Comprehensive)

The Peace-Athabasca Delta (PAD) in northern Alberta, Canada, is recognized internationally for its ecological, historical, and cultural significance. The delta is mostly within Wood Buffalo National Park, a UNESCO World Heritage Site, and is a Ramsar Wetland of International Importance. The construction of the WAC Bennett Dam (1967) and the Site C Dam (ongoing, 2024) on the Peace River, and expansion of the Alberta Oil Sands industry along the Athabasca River have raised concerns over water quantity and quality in the delta. When industry operations began, effective monitoring had not been implemented. Consequently, pre-industrial reference conditions are unknown and can …

Navigating Islands’ Political Geographies: The Case Of The 'Maduro Migrations' From Venezuela To Trinidad And Tobago, Shiva Mohan

Theses and Dissertations (Comprehensive)

Grounded in critical geopolitics and feminist political geography, this dissertation undertakes a critical examination of Trinidad and Tobago’s (T&T) responses to the inflow of Venezuelans from the “Maduro migrations” since 2015. This massive displacement was triggered by conditions of economic, political and humanitarian crisis on the Venezuelan mainland. The dissertation’s central argument is that T&T’s responses are strategic exercises in defence of its sovereignty, launched through the conscious use of its island-geographies, with a view to rejecting external dictates in its domestic affairs. The island’s responses are examined through three interrelated, but scalarly disparate foci: regional and hemispheric geopolitical influences …
