An Assessment Of Climate Variability On Farmers' Livelihoods Vulnerability In Ayeyarwady Delta Of Myanmar, Naw M. Lar, Nathsuda Pumijumnong, Raywadee Roachanakanan, Noppol Arunrat, Soe Tint

Applied Environmental Research

This study assesses the vulnerability of farm households in the Ayeyarwady Region, Myanmar. Fifty-nine farm households were purposively sampled to conduct a questionnaire survey, and secondary data were collected in 2016. In order to assess variability in household vulnerability, the Livelihood Vulnerability Index (LVI), based on five types of 'capital' as identified in the Sustainable Livelihoods Framework, was adopted and modified according to the local context. Vulnerability scores ranged from 0 (low vulnerability) to 1 (highly vulnerable), with an average LVI of 0.442, indicating moderate overall vulnerability across the study area. Regarding the five types of 'capital', households were most …

Flash Flood Risk Estimation Of Wadi Qena Watershed, Egypt Using Gis Based Morphometric Analysis, Wael M. Elsadek, Mona G. Ibrahim, Wael E. Mahmod

Applied Environmental Research

Flash flooding is one of the periodic geohazards in the eastern desert of Egypt where many parts of Upper Egypt, Sinai, and Red Sea areas were hit by severe flash floods, for example in 1976, 1982, 1996 and January 2010. The hazard degree for each sub-basin was determined using the approach developed by El-Shamy for assessing susceptibility of sub-basins to flash flooding risk. To identify at-risk sub-basins, two different methods were applied. The first method is based on the relationship between the drainage density and bifurcation ratio, and the second one uses the relationship between drainage frequency and bifurcation ratio. …

Morphometric Temporal Change Analysis For The River Nile Forced Bends Using Rs/Gis Techniques: Case Study Of Damietta Branch Of The Nile River, Egypt, Reham A.B. Aborahma, Wael E. Mahmod, Hassan E.B. Fath

Applied Environmental Research

The River Nile is one of the world's longest rivers. The Damietta branch in Egypt is important as a major source of irrigation and navigation path from Cairo to the Mediterranean Sea. Morphological changes in this branch of the Nile occurred following construction of the Aswan High Dam, which affected sedimentation and erosive flow, especially at bends in the river. In this study, morphometric temporal changes were investigated for the forced bends using Remote Sensing (RS) and Geographical Information System (GIS) techniques for a study period between 1987 and 2015. In addition, a comparative study was performed among three image …

Medical Necessity: A Higher Hurdle For Marginalized Taxpayers?, Julie Furr Youngman, Courtney D. Hauck

Loyola of Los Angeles Law Review

Civil rights protection for transgender people—and in particular access to affordable health care—is currently the subject of intense political scrutiny, with a hostile administration chipping away at legal protections. Among other setbacks, a federal district court enjoined regulatory guidelines that were issued in 2016 to clarify that the federal prohibition on sex discrimination in health insurance applies to discrimination on the basis of gender identity and transgender status, and the promulgating agency itself is now reconsidering the guidelines. Without explicit federal protections against discrimination by health insurers and in the face of uneven state law protections, the ability to deduct …

Tree Ring Dating Of The Ficklin-Imboden Log Structures, Powhatan Historic State Park, Arkansas, Kaylee R. Mcadoo, David W. Stahle

Journal of the Arkansas Academy of Science

Powhatan Historic State Park in Powhatan, Arkansas preserves and interprets five historical structures from 19^th century Arkansas, including the Ficklin-Imboden Log House. This structure, which is actually two separate log buildings with uncertain construction dates and functions, is believed to be the earliest surviving structure at Powhatan State Park and is on the National Register of Historic Places. Powhatan State Park contracted with the University of Arkansas Tree-Ring Laboratory to develop a more accurate dating and interpretation of the log structures.

Dendrochronology (tree-ring dating) was used to determine the true felling dates of logs in both buildings. Core specimens …

Implementing Climate Change Research At Universities: Barriers, Potential And Actions, Walter Leal Filho, Edward A. Morgan, Eric S. Godoy, Ulisses M. Azeiteiro, Paula Bacelar-Nicolau, Lucas Veiga Ávila, Claudia Mac-Lean, Jean Hugé

Faculty Publications - Philosophy

Many universities around the world have been active centres of climate change research. However, there are a number of barriers to climate change research, stemming both from the nature of the research and the structure of institutions. This paper offers an overview of the barriers which hinder the handling of matters related to climate change at institutions of higher education (IHEs), and reports on an empirical study to investigate these barriers using a global survey of higher education institutions. It concludes by proposing some steps which could be followed with a view to making climate change more present and effective …

Indigenous-Led Resistance To Environmental Destruction: Methods Of Anishinaabe Land Defense Against Enbridge's Line 3, Charlotte Degener Hughes

Pitzer Senior Theses

Enbridge has proposed the Line 3 “Replacement” Project, a new pipeline project taking a new route strait through Anishinaabe treaty territory in what is known as northern Minnesota. In the middle of the regulation process, the future remains unclear of how the State of Minnesota will move forward with the permitting process, but Anishinaabe communities, a range of non-profit organizations, and local landowners remain firmly against the line. Rooted in varied frameworks of Native sovereignty, the land, and Indigenous feminism, Anishinaabe communities lead the resistance against a product of ongoing settler colonialism, racial capitalism, and environmental racism. This thesis contextualizes …

Presence And Potential Sources Of Pharmaceutical And Personal Care Product Chemicals In Messalonskee Lake, Alyssa T. Kullberg

Honors Theses

Pharmaceuticals and personal care product chemicals (PPCPs) represent a large group of contaminants that are mostly not regulated in surface or drinking water and whose presence and environmental and health impacts are poorly understood. We investigated the presence and potential sources of 18 PPCPs in Messalonskee Lake. We collected samples four times over the summer of 2017 at 13 sites around the lake. Samples were tested for PPCPs using liquid chromatography-tandem mass spectrometry. We detected five out of the 18 PPCPs we tested for at the ng/L level: caffeine, 1,7-dimethylxanthine, acetaminophen, sulfachloropyridazine, and amphetamine. PPCPs showed a significant positive correlation …

Waste Reduction In Public School Cafeterias Through Sorting And Diversion: An Analysis Of Three Southern Maine Schools, Jeremy P. Ravenelle

Honors Theses

Solid waste is a serious environmental problem in the modern world. School cafeterias are one source of food and packaging waste that must be dealt with. Reducing the amount of cafeteria waste disposed of as trash through source reduction, recycling, and composting can not only improve environmental outcomes but also teach students about sustainability and save schools money. Social practice theory provides some factors that may be helpful to examine school cafeteria waste reduction programs. Using these factors, this thesis first examines school waste reduction programs in articles from academic databases, and then in three case study elementary schools in …

The Identification And Application Of Generalizable Spatial Patterns Of Human-Wildlife Conflict, Vivian F. Hawkinson

Honors Theses

Many human-wildlife conflict studies focus on one location or one individual species or taxonomic group; fewer comparative studies analyze patterns of conflict across species and regions. As a result, numerous studies report similar conclusions across diverse cases of human-wildlife conflict. I found 133 scholarly articles published between 1975 and 2017 referencing distance from a protected area boundary as a variable associated with human-wildlife conflict. I identified three generalizable patterns of human-wildlife conflict that appear across taxonomic groups and geographic locations. The family Felidae had the highest maximum average conflict distance and furthest distance from a protected area that conflict was …

Stable Bromine Isotope Signature Of Bromoform From Enzymatic And Abiotic Formation Pathways And Its Application In Identifying Sources Of Environmental Bromoform In The Damariscotta River, Chengyang Wang

Honors Theses

Bromoform is a major source of atmospheric bromine. Most bromoform is produced by marine organisms including macroalgae and phytoplankton, using the enzyme bromoperoxidase (BPO). Bromoform can also be a byproduct of industrial processes such as water disinfection. Identifying sources of environmental bromoform is still a challenge. A novel technique of using quadrupole mass spectrometry coupled to a gas chromatography (GCqMS) was developed and optimized for Br isotope analyses. The study shows that GCqMS in single ion monitoring (SIM) mode can measure 81Br with precision of around ±0.7‰ (60pmol bromoform injected). This study aims to investigate stable Br isotopes of bromoform …

Using A Custom Landscape Classification To Understand The Factors Driving Site Occupancy By A Rapidly Declining Migratory Songbird, Elizabeth K. Schold

Theses and Dissertations

Land cover classifications are useful in a broad range of ecological applications, yet publicly available classifications are not always useful for the needs of specific projects. Custom classifications are always a possibility, however, they can be financially or computationally out of reach for many researchers. Here we present a custom 1m resolution land cover classification created using freely available imagery and a random forest classification approach. This classification detected shrub cover more accurately and at a finer resolution than previous classifications. With the creation of this map, we were then able to examine landscape factors influencing occupancy dynamics of the …

Storm Surge Reconstruction And Return Water Level Estimation In Southeast Asia For The 20th Century, Alba Cid, Thomas Wahl, Don P. Chambers, Sanne Muis

Marine Science Faculty Publications

We present a methodology to reconstruct the daily maximum storm surge levels, obtained from tide gauges, based on the surrounding atmospheric conditions from an atmospheric reanalysis (20th Century Reanalysis—20CR). Tide gauge records in Southeast Asia are relatively short, so this area is often underrepresented in studies based on long observational records, and there are just a few studies that have analyzed storm surge trends, variability or return water levels (RWLs) from numerical models in this area. Here we develop, calibrate, and validate a multivariate linear regression model that relates the storm surge with the principal components of the local atmospheric …

Closing The Loop: Exploring Ikea’S Transition To The Circular Economy, Alexandra Seidel

Pomona Senior Theses

Inspired by the way nature cycles waste in an ecosystem, the circular economy was developed as an alternative to the linear take-make-dispose model and designed to decouple economic growth from resource use. After developing a framework for what it means to be a business pursuing circularity, this thesis examines six different companies to explore the tension between the strategies and business models in theory and what business are implementing in practice today. This exploration continues with an in-depth analysis of the circular success of IKEA, finding that the gains from the circular economy for a large corporation are found within …

Immigration As A Social Determinant Of Health: Proceedings Of A Workshop, Tiffiany O. Howard, National Academies Of Sciences, Engineering, And Medicine, Numerous Authors, See Full List Below

Political Science Faculty Research

Since 1965 the foreign-born population of the United States has swelled from 9.6 million or 5 percent of the population to 45 million or 14 percent in 2015. Today, about one-quarter of the U.S. population consists of immigrants or the children of immigrants. Given the sizable representation of immigrants in the U.S. population, their health is a major influence on the health of the population as a whole. On average, immigrants are healthier than native-born Americans. Yet, immigrants also are subject to the systematic marginalization and discrimination that often lead to the creation of health disparities. To explore the link …

This checklist was compiled from Gordon Natural Area (GNA) Staff fieldwork in 2017-2018, augmented by photos from former GNA Stewardship Manager Gerry Hertel, GNA Interns, students and visitors from 2007 to present and by the 17 'identified species' (i.e., not counting 'morphospecies', e.g., 'Unknown Shelf Fungus') in Levy et al. 2008. The checklist contains 268 species in 178 Genera and 92 Families. Species are organized in three 'groupings': Slime Molds (19 species); Ascomycetes (52 species); and, Basidiomycetes ( 196 species). Although slime molds aren't properly 'fungi', they are closely related to fungi and are often included in mycological studies. Hence, …

Sustainability-Efficiency Paradox: The Efficacy Of State Energy Plans In Building A More Sustainable Energy Future, Austin Zimmerman

Pitzer Senior Theses

State energy plans are created at the request of a sitting governor or State Legislature in order to provide guidance set goals for the state’s energy sector. These plans will be critical indicators of energy trends such as the future market share of coal, natural gas, and renewables. If the future of energy in the United States is to be remotely sustainable, low-carbon policies must headline state plans. The strength of a state’s energy plan in terms of sustainability is directly related to that state’s willingness to prioritize and commit to incorporating energy sources that produce negligible carbon emissions. Questions …

Real Property Sublessors Escape Cercla Owner Liability In The Second Circuit, Alison Shlom

PEEL Alumni Scholarship

Under federal law, a tenant who subleases a property to a sublessee who contaminates the site may be liable for cleanup costs depending on which federal court hears the case. The Comprehensive Environmental Response, Compensation, and Liability Act's (CERCLA) circular definition of a property "owner" has resulted in a circuit split on this issue. ln the Second Circuit, courts rely on a five-factor test to determine owner liability. In sharp contrast, the Ninth Circuit incorporates state-specific law to assign owner liability.
