The Process Of Reclaiming Tribal Sovereignty Through Healthcare Autonomy, Karolina A. Serhan
The Process Of Reclaiming Tribal Sovereignty Through Healthcare Autonomy, Karolina A. Serhan
Honors Theses
This honors thesis explores the complex interplay between health status, healthcare, and tribal sovereignty among native communities in the United States. These relationships are explored through analyzing the paradoxical and condescending nature of the Federal Trust Responsibility in relation to government-organized healthcare programs for natives. In establishing this relationship, the thesis goes on to illustrate how native communities have effectively fought to regain sovereignty through reclaiming autonomy of their healthcare systems through the use of the 1975 Indian Self-Determination and Education Assistance Act. The impact of tribal-led healthcare systems is further explored through an in-depth case study conducted regarding the …

Environment and Society Faculty Publications
The Conservation Effects Assessment Project (CEAP) was created in response to a request from the Office of Management and Budget that the U.S. Department of Agriculture, Natural Resource Conservation Service (USDA- NRCS) document the societal benefits anticipated to accrue from a major increase in conservation funding authorized by the 2002 Farm Bill. A comprehensive evaluation of the efficacy of rangeland conservation practices cost- shared with private landowners was unable to evaluate conservation benefits because outcomes were seldom documented. Four interrelated suppositions are presented to examine the causes underlying minimal documentation of conservations outcomes. These suppositions are (1) the benefits of …

Restoring And Sustaining Smallholder Kappaphycus Alvarezii Farming Post-Typhoon Haiyan/Yolanda In Molocaboc, Central Philippines, David C. Fenlon
Dissertations, Master's Theses and Master's Reports
The farming of marine seaweed has the potential to provide both nutritional and financial resources to developing communities such as the Molocaboc Islands in the Philippines. To foster this mariculture development approximately $1,000 USD in grant funds received from the US-Philippines Society was used to purchase materials needed to replace seaweed production infrastructure lost to Typhoon Haiyan (known as Super Typhoon Yolanda in the Philippines). The goal was to restore and expand smallholder farming of the seaweed Kappaphycus alvarezii (locally known as ‘guso’ in the Visayan dialect) in the Molocaboc Islands, thereby increasing harvest yields as compared to those …

Cultural Influences On Taiwanese Environmental Non-Governmental Organizations' Strategies And On Public Perceptions Of Their Strategies, Li-Yin Liu
Graduate Research Theses & Dissertations
The strategies of environmental non-governmental organizations (ENGOs) and public perceptions of environmental activism in Taiwan are arguably crucial, yet understudied determinants, of types of environmental activism and of public support for environmental policies. Accordingly, this study sought answers to several important unasked questions in environmental governance and public opinion research: 1) How do ENGOs' decision makers decide what types of environmental activities to pursue? 2) What role does ENGOs' organizational culture play in their decision making? 3) How does the public perceive different types of environmental activism? And 4) How does culture influence these perceptions? To answer these questions, this …
Geophysical Characterization Of The Big Marsh Slag Site In Chicago, Illinois, Sonny Divita
Geophysical Characterization Of The Big Marsh Slag Site In Chicago, Illinois, Sonny Divita
Graduate Research Theses & Dissertations
Wetlands in the Lake Calumet region of Chicago, IL have been filled in with slag for over 100 years. Dissolution of slag at the Big Marsh wetland site near Lake Calumet has led to extremely alkaline ponds and groundwater contamination. The purpose of this research was to delineate contaminated groundwater zones, estimate porosity of the slag, and determine lithology at Big Marsh. A suite of geophysical instrumentation consisting of electromagnetic (EM) conductivity, magnetometry, ground penetrating radar (GPR), vertical electrical soundings (VES), and two-dimensional electrical resistivity imaging (2D-ERI) were used to conduct surface investigations. Average groundwater resistivity (rhow) at the site …
Sustaining Uber: Opportunities For Electric Vehicle Integration, David Wagner
Sustaining Uber: Opportunities For Electric Vehicle Integration, David Wagner
Pomona Senior Theses
Uber and Lyft, the “unregulated taxis” that are putting traditional taxi companies out of business, are expanding quickly and changing the landscape of urban transportation as they go. This thesis analyzes the environmental impacts of Transportation Network Companies, particularly in California, with respect to travel behavior, congestion, and fuel efficiency. The analysis suggests that fuel efficient taxis are being replaced by less fuel efficient Uber and Lyft vehicles. Linear regressions were run on data from the Clean Vehicle Rebate Project’s Electric Vehicle Consumer Survey of electric vehicle owners in California. The findings indicate that Uber drivers are more reliant upon …
Lost Opportunities: Ecuador's Yasuní Itt Initiative, Julianna Hitchins
Lost Opportunities: Ecuador's Yasuní Itt Initiative, Julianna Hitchins
Pomona Senior Theses
In 2007, President Rafael Correa of Ecuador proposed the Yasuní ITT Initiative at the United Nations General Assembly in an effort to contribute to the reduction of carbon dioxide emissions and the local preservation of biodiversity. The initiative proposed enacting an indefinite ban on oil exploration and extraction within the Ecuadorian Yasuní National Park so long as the developed world was willing to contribute to half the forgone costs of drilling. However, despite initial support, the Yasuní Initiative was unsuccessful, and due to a lack of financial support, Correa terminated the proposal in August 2013.
With the increasing threat of …
Climate Change Adaptation For Southern California Groundwater Managers: A Case Study Of The Six Basins Aquifer, Frank Lyles
Climate Change Adaptation For Southern California Groundwater Managers: A Case Study Of The Six Basins Aquifer, Frank Lyles
Pomona Senior Theses
Groundwater has been very important to the economic development of Southern California, and will continue to be a crucial resource in the 21st century. However, Climate Change threatens to disrupt many of the physical and economic processes that control the flow of water in and out of aquifers. One groundwater manager, the Six Basins Watermaster in eastern Los Angeles and western San Bernardino Counties, has developed a long-term planning document called the Strategic Plan that mostly fails to address the implications of Climate Change, especially for local water supplies. This thesis presents an in-depth analysis of the Six Basin Watermaster’s …
Roots Of A Movement: Community Action And The Impact Of Urban Agriculture In Chicago, Maia Welbel
Roots Of A Movement: Community Action And The Impact Of Urban Agriculture In Chicago, Maia Welbel
Pomona Senior Theses
Efforts to maintain a relationship to food pathways have been consistent throughout U.S. history despite the general evolution towards an increasingly industrialized food system. Urban agriculture serves as a means of reclaiming and furthering knowledge of where food comes from while also addressing larger social, economic, and environmental goals. This has been demonstrated in Chicago where urban farmers have worked to improve food access, increase employment, and revitalize communities all across the city. For many years, federal policies have promoted maximum production of commodity crops and kept supermarket prices low, allowing the government to ignore the impacts these policies are …

The Effects Of Thermal Stress On Fluorescent Protein Expression In An Indo-Pacific Scleractinian Coral Species, Acropora Tenuis, Anna Knochel
Independent Study Project (ISP) Collection
The scleractinian coral species that so heavily define tropical coral reefs are increasingly threatened by anthropogenic global warming. Rising sea surface temperatures in combination with light stress causes the photosynthetic breakdown of the coral’s algal symbiont, Symbiodinium. Corals have developed a number of physiological responses to handle acute stressors, such as the production of ultraviolet-protecting amino acids, heat shock proteins, the ability to shift symbionts, and the production of fluorescent proteins. The latter has been thought to play a photoprotective role in the coral holobiont, and studies have shown evidence that corals orient these pigments to divert harmful light away …

Novel Use Of Field-Portable-Xrf For The Direct Analysis Of Trace Elements In Marine Macroalgae., Annie Bull, Murray T. Brown, Andrew Turner
Novel Use Of Field-Portable-Xrf For The Direct Analysis Of Trace Elements In Marine Macroalgae., Annie Bull, Murray T. Brown, Andrew Turner
School of Geography, Earth and Environmental Sciences
Samples of dried marine macroalgae (Fucus serratus, Palmaria palmata and Ulva lactuca) have been analysed for trace elements by a novel, non-destructive approach involving a Niton field-portable-X-ray fluorescence (FP-XRF) spectrometer configured in a low density plastics mode with thickness correction. Detection limits for a 200-s counting time ranged from <5 μg g(-1) for As and Pb in F. serratus and As in P. palmata to several tens of μg g(-1) for Cd, Sb and Sn in all species tested. Arsenic, Cu, Pb and Zn were detected by the XRF in samples collected from a protected beach (n = 18) and in samples therefrom that had been exposed to additional aqueous elements in combination (n = 72) with concentrations returned (in μg g(-1)) ranging from 3.9 to 39.7 for As, 13.0 to 307 for Cu, 6.1 to 14.7 for Pb and 12.5 to 522 for Zn. Independent measurements of trace elements in the macroalgae by ICP-MS following nitric acid digestion revealed a direct and significant proportionality with concentrations returned by the XRF, with slopes of the XRF-ICP relationships (As = 1.0; Cu = 2.3; Pb = 2.4; Zn = 1.7) that can be used to calibrate the instrument for direct measurements. The approach shows potential for the in situ monitoring of macroalgae in coastal regions that is currently being investigated.

Using Recycled Water For Potable Reuse In Santa Clara County, Ca: High School Students' Knowledge And Acceptance, Nicholas Ronald Ajluni
Using Recycled Water For Potable Reuse In Santa Clara County, Ca: High School Students' Knowledge And Acceptance, Nicholas Ronald Ajluni
Master's Theses
The drought-prone State of California has an ever increasing demand for water. Potable reuse provides a viable alternative water supply, but public attitudes, knowledge, and acceptance have limited implementation. This study investigated the knowledge and acceptance that high school students have towards potable reuse. Previous research has identified four critical factors that influence acceptance of potable reuse: 1) knowledge of the wastewater treatment process, 2) knowledge of local water supplies, 3) trust in local water resource managers, and 4) belief in the need for a new water supply. This study uses both quantitative and qualitative methods through a Likert-style survey …
Grower Attitudes Towards Water Management Strategies While Mitigating Seawater Intrusion: A Case Study Of The Castroville Seawater Intrusion Project, Jason Ray Reed
Master's Theses
The Salinas River Valley Watershed has endured the effects of seawater intrusion for decades caused by overpumping groundwater from the Salinas River Groundwater Basin. The Castroville Seawater Intrusion Project began delivering recycled water in 1998 with other water sources due to wells becoming too saline. One-on-one, in-person interviews with eighteen growers, who own or lease farmland within the Project’s service area, were conducted during a severe, statewide drought. Interview questions explored grower attitudes and concerns regarding their water supply, and the impact of management strategies on the mitigation of seawater intrusion. Two research questions were posed, exploring factors that influence …

The Pacific Coast population of the western snowy plover (Charadrius nivosus nivosus; plover) is listed as a federally threatened species under the U.S. Endangered Species Act due to poor reproductive success from anthropogenic habitat loss, and high predation pressure. Plovers in the South San Francisco Bay use dry salt evaporation ponds, and wildlife-managed ponds, to breed and winter. However, the South Bay Salt Pond Restoration Project aims to restore up to 6,110 hectares of this habitat back to native tidal marsh, which will force plovers to breed in smaller areas and in higher densities. In order to recover plovers in …

Environmental And Climate Justice Along The Brahmaputra River In Northeast India, Costanza Rampini
Faculty Publications, Environmental Studies
The glaciers of the Himalayas are the source of all of Asia’s major rivers and are crucial to Asia’s water supply, economies, and livelihoods. The Himalayan region is uniquely vulnerable to the impacts of anthropogenic climate change, while also becoming one of the most dammed regions in the world. This case study explores the unequal distribution of the impacts of climate change and dam building along the Brahmaputra River in Northeast India. It examines how the combined impacts of these two processes negatively affect local communities and explores environmental and climate justice issues. In discussing climate change impacts and hydropower …
Subsurface Transport In A North Inlet, South Carolina Salt Marsh: A Porewater Salinity Model, Carolyn Ryan
Subsurface Transport In A North Inlet, South Carolina Salt Marsh: A Porewater Salinity Model, Carolyn Ryan
Theses and Dissertations
Subsurface transport in coastal salt marshes influences the nutrient budget of coastal environments, but is not fully understood. To expand our understanding of this transport, a simple numerical model was developed. The model simulated vertical transport of salt through the surficial muds at a North Inlet marsh on the coastal plain of South Carolina. To improve the model, a tracer study was utilized to calculate the average velocity of groundwater flow through the system. The model was compared with porewater salinity measured using tension samplers and passive diffusion samplers. Each method produced different, uncorrelated results. However, accounting for macro-pores in …
