Cadmium Exposure And Residence-To-Road Proximity In Eastern Kentucky, Ellen Flora

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Background and Objectives

Cadmium is a carcinogenic and toxic metal. The general population can be exposed to cadmium from multiple sources. The purpose of this study is to evaluate the association of urinary cadmium and residence distance-to-road by performing landscape analyses in eastern Kentucky, a region where smoking prevalence is high, coal production has been a primary industry, and the landscape is predominantly undeveloped. Composite dust samples were also collected and analyzed for Cadmium (Cd), Manganese (Mn), and Zinc (Zn). The primary objective of this study is to ascertain if there is an association between participants with elevated accumulated cadmium …

“Sacrifice Zones” In The Green Energy Economy: Toward An Environmental Justice Framework, Dayna Scott, Adrian A. Smith

Articles & Book Chapters

The environmental justice movement validates the grassroots struggles of residents of places which Steve Lerner refers to as “sacrifice zones”: low-income and racialized communities shouldering more than their fair share of environmental harms related to pollution, contamination, toxic waste, and heavy industry. On this account, disparities in wealth and power, often inscribed and re-inscribed through social processes of racialization, are understood to produce disparities in environmental burdens. Here, we attempt to understand how these dynamics are shifting in the green energy economy under settler colonial capitalism. We consider the possibility that the political economy of green energy contains its own …

The Abstract Subject Of The Climate Migrant: Displaced By The Rising Tides Of The Green Energy Economy, Dayna Scott, Adrian A. Smith

Articles & Book Chapters

A controversial proposal to build the mammoth ‘Site C’ dam on the Peace River in northwestern Canada offers an opportunity to explore the intersections of climate and migration issues under debate in international environmental governance circles. Site C threatens to flood traditional fishing spots and traplines of Indigenous peoples in the name of the ‘green energy’ economy. We consider how people displaced by renewable energy projects justified as climate mitigation policies might constitute a different kind of ‘climate refugee’ in that they are ‘displaced without moving’ – the connections between the land and the people are severed to the extent …

First Nations And Adaptive Water Governance In Southern Ontario, Canada, Thomas Dyck

Theses and Dissertations (Comprehensive)

Water quality and quantity are prominent concerns for First Nations across Canada. The federal government shares the responsibility with First Nations to ensure water resources on-reserves meet the needs of First Nations. Federal approaches have been predominantly technical, focused on addressing issues related to infrastructure, maintenance, training, and monitoring. This approach is important. However, water issues concerning First Nations go beyond technical issues and relate to inadequate participation in decision making, poorly defined roles and responsibilities, and approaches to managing water resources on-reserve that have not accounted for local context. These issues parallel historical nation-to-nation (i.e., First Nations and federal …

Impact Of Linear Disturbances On A Discontinuous Permafrost Peatland Environment, Michael Braverman

Theses and Dissertations (Comprehensive)

Permafrost is ground that remains at or below 0°C for at least two consecutive years (PIWP, 2012). In the continuous permafrost zone its thickness may exceed 300 m, in lower latitudes, permafrost thickness is progressively decreasing, its occurrence becomes discontinuous and eventually sporadic (PIWP, 2012). At the southern fringe of permafrost in northwestern Canada, just about few meters. In subarctic peatlands permafrost is one of the main elements governing the hydrological processes. Being very thin and with temperature just fractions of the degree below 0^oC, it is very vulnerable to any changes in soil temperature and water content. …

Accountability, Conservation And Community: Measuring The Local Economic Impacts Of Protected Areas, Catharine A.M. Brazeau

Theses and Dissertations (Comprehensive)

As a signatory to the Convention on Biological Diversity, Canada has committed to help protect biodiversity through an increase in effectively and equitably managed systems of protected areas (PAs) by 2020. If Canada fulfills this commitment, the country will see the largest expansion of PA networks in its history. Although employing ‘equitable and effective management’ suggests PAs have a responsibility to consider their effects on local stakeholders, on the whole, Canada’s PA agencies do not publicly and systematically report on their jurisdictions’ local economic impacts. To address this gap, this thesis aims investigate mechanisms for PA agencies to identify and …

Newcomers, Welcome? Exploring The Connection Between Demographic Change, Immigration Legislation Design And Policy Mobilities In Ageing Japan, Héctor Goldar Perrote

Theses and Dissertations (Comprehensive)

Japan is ageing, and its population is declining. Given the potential detrimental economic and social consequences brought about by this sort of demographic change, it has been suggested that the Japanese could benefit from the implementation of more liberal (im)migration policies. This thesis studies the demographic change – immigration policy development nexus from the perspective of the state in the context of Japan and assesses the role that immigration plays within the larger population debate. A constructivist grounded theory methodology is utilised to analyse primary and secondary qualitative data. Additionally, two theoretical approaches of political demography (Robbins and Smith, 2016) …

Capturing In-Situ Feelings And Experiences Of Public Transit Riders Using Smartphones, Rafik Said, Rafik Said

Theses and Dissertations (Comprehensive)

High-density urban environments are susceptible to ever-growing traffic congestion issues, which speaks to the importance of implementing and maintaining effective and sustainable transportation networks. While transit oriented developments offer the potential to help mitigate traffic congestion issues, transit networks ought to be safe and reliable for ideal transit-user communities. As such, it is imperative to capture meaningful data regarding transit experiences, and deduce how transit networks can be enhanced or modified to continually maintain ideal transit experiences. Historically speaking, it has been relatively tricky to measure how people feel whilst using public transportation, without leaning on recall memory to explain …

Marine Protected Areas In Colombia: Re-Connecting Social, Ecological, And Policy Aspects Through A Governance Perspective, Luisa Ramirez

Theses and Dissertations (Comprehensive)

The purpose of this doctoral research is to examine opportunities and constraints for integrating key aspects of governance into marine conservation strategies and for shifting top-down approaches toward collaborative and integrative forms of governance that enhance conservation and social outcomes in marine protected areas (MPAs).

Although there is evidence that demonstrates that MPAs are an effective tool for marine conservation, shortcomings in addressing ecological characteristics and particularly in addressing social factors in the design and planning of MPAs often constrain achieving conservation and sustainability goals. These shortcomings are particularly acute in MPAs implemented through top-down governance approaches that overlook stakeholder …

Assessing Resilient Post-Disaster Recovery Of A Flash-Flood-Prone Area: A Study Of The City Of Jeddah, Kingdom Of Saudi Arabia, Abdurazag Tammar

Theses and Dissertations (Comprehensive)

Abstract

The increased incidence of natural disasters over recent decades has been accompanied by a corresponding dramatic proliferation of human casualties, economic damage and recovery costs. Post-disaster processes are therefore increasingly becoming the paramount focus of disaster-management stakeholders. Current research has noted the importance of improving community resilience with respect to household capacity, organizational capacity, and social capital, as the three main assessment dimensions to enable communities to recover effectively and efficiently from future disaster events. Community resilience involves proactive preparedness and mitigation initiatives. In the context of the Kingdom of Saudi Arabia, the lack of either precedent research or …

Saroja Voruganti, Matthew O. Gribble, Karin Haack, Sandra Laston, Jason G. Umans, Kevin A. Francesconi, Walter Goessler

School of Medicine Publications

Background:

Metabolism of inorganic arsenic (iAs) is subject to inter-individual variability, which is explained partly by genetic determinants.

Objectives:

We investigated the association of genetic variants with arsenic species and principal components of arsenic species in the Strong Heart Family Study (SHFS).

Methods:

We examined variants previously associated with cardiometabolic traits (~ 200,000 from Illumina Cardio MetaboChip) or arsenic metabolism and toxicity (670) among 2,428 American Indian participants in the SHFS. Urine arsenic species were measured by high performance liquid chromatography–inductively coupled plasma mass spectrometry (HPLC-ICP-MS), and percent arsenic species [iAs, monomethylarsonate (MMA), and dimethylarsinate (DMA), divided by their sum …

Chromatographic Analysis Of Low Molecular Weight Polar Compounds In Complex Environmental Matrices And Renewable Materials, Jana Rousova

Theses and Dissertations

One of the challenges in characterization of complex environmental matrices and renewable materials is the determination low molecular weight polar compounds (LMWPCs). Depending on the matrix, the targeted LMWPCs include acids, aldehydes, sugars, sugar alcohols or aminoacids. To investigate the role and impact of these species, a development of accurate and precise analytical protocols is essential. One of the challenges in analysis of LMWPCs is their volatility and thus potential losses during sample preparation. The various matrices including renewable materials may contain >100 compounds that are either non-targeted (i.e., their identity is not known prior to the analysis) or targeted …

To Nudge Or Not To Nudge: Promoting Environmentally Beneficial Behaviors, Emma Jean Cooper

Bard Center for Environmental Policy

In order to mitigate the effects of climate change, humans need to change how they act toward the environment. Unfortunately, as much as we may want to act in ways that would be best for us and for the environment, we often struggle to do just that due to cognitive biases. Nudge theory attempts to remedy this problem by helping us make the decision that would be in our best interests. To explore this issue, I conduct an extended review of the literature to examine how well nudge theory can be applied to the realm of environmental policy. Specifically, I …

Seed Policy In Pakistan: The Impact Of New Laws On Food Sovereignty And Sustainable Development, Amna Tanweer Yazdani, Nosheen Ali

Institute for Educational Development, Karachi

This paper highlights the challenges that genetically modified (GM) seeds pose for farmers, citizens and the land itself in Pakistan. It explores the history of agricultural policy in Pakistan from the Green Revolution to what is now being dubbed the “Gene Revolution”, and analyzes how harmful effects of both are being amplified by two recently passed laws: the Seed (Amendment) Act 2015 and the Plant Breeders' Rights Act 2016. The analysis of these laws is done from a food sovereignty perspective on sustainable development, where food sovereignty represents “the right of peoples to healthy and culturally appropriate food produced through …

Stand Clear Of The Closing Doors, Please: Transit Equity, Social Exclusion, And The New York City Subway, Taylor Novick-Finder

Pitzer Senior Theses

The history of transportation planning in New York City has created disparities between those who have sufficient access to the public transportation network, and those who face structural barriers to traveling from their home to education, employment, and healthcare opportunities. This thesis analyzes the legacy of discriminatory policy surrounding the Metropolitan Transportation Authority (MTA) and city and state governments that have failed to support vital infrastructure improvement projects and service changes to provide multi-modal welfare to New York’s working poor. By exploring issues of transit equity as they pertain to the New York City subway system, this thesis raises the …

Ugh…Statistics! College Students’ Attitudes And Perceptions Toward Statistics, Drew A. Doyle

Honors Undergraduate Theses

Statistics is a course that is required for a majority of undergraduate college students in a wide variety of majors. It is not just required for Statistics or Mathematics majors, but also for those undergraduate college students majoring in Biology, Engineering, Sociology, and countless other majors. It can often be seen as a daunting course, especially for those who feel that mathematics is not their strongest subject. Students begin to dislike the course before even starting and this can carry on throughout the entirety of the course. This thesis will focus primarily on students’ perceptions and attitudes toward their statistics …

Archaeological Gis Analysis Of Raised Field Agriculture In The Bolivian Amazon, Thomas W. Lee

Honors Undergraduate Theses

Modern agricultural systems have been criticized for their detrimental effects on the environment and a general emphasis on crop yield rather than long-term sustainability. Traditional forms of agriculture may provide case-specific examples of sustainable alternatives for contemporary societies. In the seasonally inundated savannas of the Llanos de Mojos, pre-Columbian Indians piled earth into ‘large raised field platforms’ elevated high enough above the floodplain to allow crops to grow. Archaeological evidence indicates that raised field agriculture supported much larger populations than those found in the Beni today. The examination of satellite imagery has revealed more than 40,000 individual fields spread across …

Micro-Spectroscopy Of Bio-Assemblies At The Single Cell Level, Jeslin Kera

Honors Undergraduate Theses

In this thesis, we investigate biological molecules on a micron scale in the ultraviolet spectral region through the non-destructive confocal absorption microscopy. The setup involves a combination of confocal microscope with a UV light excitation beam to measure the optical absorption spectra with spatial resolution of 1.4 μm in the lateral and 3.6 μm in the axial direction. Confocal absorption microscopy has the benefits of requiring no labels and only low light intensity for excitation while providing a strong signal from the contrast generated by the attenuation of propagating light due to absorption. This enables spatially resolved measurements of single …

Exploring The Socio-Ecological Dimensions Of Agricultural Expansion In New Hampshire, Jennifer Wilhelm

Doctoral Dissertations

Forest ecosystems and agriculture represent coupled socio-ecological systems that are shaped by human activity. The extensification of agriculture (expansion of food production on the landscape) can cause significant changes in land use, and can contribute to the degradation of biodiverse ecosystems and the services these systems provide. Yet the need to increase food production capacity, either through agricultural intensification or extensification, continues to rise. In this dissertation, I address the critical issue of agricultural extensification from several angles.

The first chapter assesses agricultural expansion through the lens of urban and peri-urban agriculture (UPA) through systematic review of the literature. I …

Effects Of Alien Shrubs On Caterpillars And Shrubland-Dependent Passerines Within Three Transmission Line Rights-Of-Way In Southeastern New Hampshire, Matthew Tarr

Doctoral Dissertations

By altering plant species composition and reducing plant species richness, invasion of non-native (alien) plants can reduce caterpillar abundance in bird habitats and simplify the bird community, but whether these cascading effects of alien plants extend further to affect bird productivity has not been quantified. This study is the first to quantify how reduced caterpillar abundance associated with alien plant invasion affects the reproductive success of a breeding passerine, the common yellowthroat (Geothlypis trichas trichas). The study was conducted in three transmission line rights-of-way where plant composition in yellowthroat territories was dominated by a near monoculture of alien shrubs (“ALIEN” …

Nitrogen Dynamics And Retention In The River Network Of A Tropical Forest, Luquillo Mountains, Puerto Rico, Richard Brereton

Doctoral Dissertations

This dissertation identifies gaps in the scientific understanding of nutrient cycling, particularly nitrogen (N) cycling, in streams and riparian zones of tropical montane forests, and addresses several of those gaps with original field-based research using study watersheds in the Luquillo Mountains of Puerto Rico as the model system. The Luquillo Mountains have features typical of mature montane tropical forests, such as high background N concentrations in streams and groundwater relative to streams in other biomes. As a USDA Forest Service Experimental Forest, the Luquillo Mountains are accessible to researchers and have abundant monitoring and experimental datasets from which to build …

Unraveling Short-Term Variations In Tidewater Glacier Flow: Insights From Terrestrial Radar Interferometric Studies, Ryan Cassotto

Doctoral Dissertations

Tidewater glaciers are fast-flowing valley glaciers that advect ice from the interior of ice sheets to the ocean. Processes along the submarine boundaries of tidewater glacier termini can trigger a dynamic response in glacier ice that can impact stability along the terminus. Predictions of 21st century sea level rise require a comprehensive understanding of tidewater glacier dynamics over a variety of spatial and temporal scales. Perturbations to the calving front, such as iceberg calving, tidal modulations, changes in proglacial ice mélange strength and rigidity, and the subglacial discharge of meltwater occur on time-scales that exceed temporal resolution of satellite measurements; …

Effects Of Agricultural Practices On Soil Communities And Their Associated Ecosystem Services, Lesley W. Atwood

Doctoral Dissertations

To maximize crop yields, commodity crop production systems typically rely on inputs of fertilizers, pesticides, and irrigation; simplification of crop rotations (e.g., monocultures); and strategic use of soil disturbance (e.g., tillage, cultivation, etc.). While these practices are intended to optimize the soil conditions for crop development and reduce spatial and temporal variability in crop yield, they also impact soil biological diversity and the important agroecosystem services soil communities provide. Identification of management practices that are less prone to causing undesirable changes in the soil food web community are central to improving the sustainability of our agricultural systems. In this dissertation, …

Faculty & Staff Scholarship

Many ecosystem processes that influence Earth system feedbacks – vegetation growth, water and nutrient cycling, disturbance regimes – are strongly influenced by multidecadal- to millennial-scale climate variations that cannot be directly observed. Paleoclimate records provide information about these variations, forming the basis of our understanding and modeling of them. Fossil pollen records are abundant in the NE US, but cannot simultaneously provide information about paleoclimate and past vegetation in a modeling context because this leads to circular logic. If pollen data are used to constrain past vegetation changes, then the remaining paleoclimate archives in the northeastern US (NE US) are …
