Testing Methods To Mitigate Caribbean Yellow-Band Disease On Orbicella Faveolata, Carly J. Randall, Elizabeth M. Whitcher, Tessa Code, Clayton Pollock, Ian Lundgren, Zandy Hillis-Starr, Erinn M. Muller

United States National Park Service: Publications

Outbreaks of coral diseases continue to reduce global coral populations. In the Caribbean, yellow band is a severe and wide-spread disease that commonly affects corals of the Orbicella spp. complex, significantly impeding coral reproduction, and hindering the natural recovery of Orbicella spp. populations. Caribbean yellow-band disease (CYBD) lesions may be severe, and often result in the complete loss of coral tissue. The slow spread of CYBD, however, provides an opportunity to test methods to mitigate the disease. Here we report the results of in situ experiments, conducted within Buck Island Reef National Monument in St. Croix, USVI, to test the …

The Impact Of National Culture On Corporate Environmental Performance: How Much Does Your Origin Say About How Green You Are?, Felice Petruzzella, Antonio Salvi, Anastasia Giakoumelou May 2018

The Impact Of National Culture On Corporate Environmental Performance: How Much Does Your Origin Say About How Green You Are?, Felice Petruzzella, Antonio Salvi, Anastasia Giakoumelou

Journal of Environmental Sustainability

This paper aims to study the effect of national culture on corporate environmental responsibility practices and commitment. To this end, we employ the Hofstede framework of cultural dimensions in order to examine each cultural aspect’s power to predict a firm’s environmental performance. Furthermore, we explore the potential of national environmental commitment as a moderator of the relationship between national culture and corporate environmental performance.

Our findings, deriving from a sample of 591 corporations of the S&P 1200 index, suggest that a firm’s environmental performance is influenced by the culture characterizing its country of origin. Among the cultural aspects that function …


Climate Communication Through A Community Perspective, Kathryn Mcgee May 2018

Climate Communication Through A Community Perspective, Kathryn Mcgee

Senior Honors Projects, 2010-2019

This project utilized psychology and science communication strategies to develop creative, locally framed climate change messaging. Through an online survey of 300 Gloucester County, VA residents, community themes of place attachment, environmental connection, risk assessment and climate change acceptance were recorded. Using the results from the survey I created a website, https://guidinggloucester.wixsite.com/home, which serves as an avenue for communicating with Gloucester residents. The website displays the results of the survey, explains climate change information that is relevant to Gloucester County, and gives examples of local actions to help increase engagement in climate solutions. In addition to the website, I …

A Socioeconomic Valuation Of Urban Wetland Ecosystems And Policy Recommendation For College Lake, Michael Dunmyer May 2018

A Socioeconomic Valuation Of Urban Wetland Ecosystems And Policy Recommendation For College Lake, Michael Dunmyer

Undergraduate Theses and Capstone Projects

Cityscapes in the United States are often viewed dichotomously in regards to natural environments. Preserved sites can be seen as an obstacle to urban development, and the concept of a functioning ecosystem within city limits is fictitious to many; we assume the two cannot coexist. Lynchburg, Virginia’s College Lake offers a unique case study for how urban ecosystems can not only subsist within cities but provide pivotal functions for them as well. With the potential for a dam-breaching storm event increasing in possibility with each passing year, concerns regarding the structural integrity of the College Lake dam in Lynchburg, Virginia …


(In)Visibility And Meaning In Food Labor: A Feminist Autoethnography, Kathryn Shedden May 2018

(In)Visibility And Meaning In Food Labor: A Feminist Autoethnography, Kathryn Shedden

Masters Theses, 2010-2019

My graduate thesis project entitled “(In)visibility and Meaning in Food Labor: A Feminist Autoethnography” illuminates the gendered experiences of female food laborers and how women make meaning through their labor in this context. Gendered experiences do not stand apart from classed and raced identities, which I also reflexively analyze throughout this thesis. Women working within the food chain have been historically marginalized and made invisible, though they make up an increasingly significant portion of this workforce, a trend known as the “feminization of agriculture.” The discussion of the work that women do when discussing food in the academic literature also …

Seabird Distribution And Oil & Gas Potential Along The Northern Sea Route, Russia: An Arctic Marine Conservation Case Study, Meghan Kelly May 2018

Seabird Distribution And Oil & Gas Potential Along The Northern Sea Route, Russia: An Arctic Marine Conservation Case Study, Meghan Kelly

Sustainability and Social Justice

Seabirds are indicator species for the marine environment. Their populations are simultaneously affected by access to food resources and anthropogenic pressures including direct disturbance and habitat degradation associated with industrial development (Parsons et al. 2007). Therefore, using seabird distribution as a policy-relevant indicator for the Arctic marine environment supports an ecosystem based management approach aimed at protecting sensitive habitats from increased offshore oil and gas development.

This research identifies seabird habitat in the Russian Arctic utilizing in situ seabird observations from the Northern Sea Route to create a species distribution model. The spatial location of these areas will be compared …

Exploring The Potential Of Environmental Impact Investing For Sustainable Development: The Cases Of Dominion Energy And Tesla Motors, Christopher Dibble May 2018

Exploring The Potential Of Environmental Impact Investing For Sustainable Development: The Cases Of Dominion Energy And Tesla Motors, Christopher Dibble

Sustainability and Social Justice

The health of our planet and the existence of our species faces an uncertain future. Climate change is the single largest issue facing society today, as carbon-based fuel and combustion engines have driven development in nearly every industry. Public investment through securities markets have enabled corporations to extract coal and oil, build combustion engines, and distribute fuel commercially for over one hundred and fifty years. However, it is now widely accepted that if business-as-usual continues, carbon emissions will cause irreversible and devastating effects to the environment and humankind. International, national, local governments, companies, and general populations have taken steps to …


United In The Struggle: The Role Of Land Titles For Communities Of Internally Displaced Persons In El Salvador, Corie Welch May 2018

United In The Struggle: The Role Of Land Titles For Communities Of Internally Displaced Persons In El Salvador, Corie Welch

Multiple episodes of dispossession and displacement characterize the lives of landless rural and semi-rural families across El Salvador. The residents of 30 de Abril, a semi-rural community in El Salvador formed from displaced families, engaged in a five-year struggle to force the government to make good on its promise of land to the rural poor. Now, with legal titles in hand, residents continue to work together to seek additional services and resources for their community, proving their resilience in the face of displacement. Based upon the experience of 30 de Abril, this paper explores the trajectory of one community‟s struggle …


Degrowth Lessons From Cuba, Claire S. Bayler May 2018

Degrowth Lessons From Cuba, Claire S. Bayler

Sustainability and Social Justice

Cuba is the global leader in practicing agroecology, but agroecology is just one component of a larger climate-ready socio-economic system. Degrowth economics address the need to constrain our total global metabolism to within biophysical limits, while allowing opportunity and resources for "underdeveloped" countries to rebuild themselves under new terms. Degrowth recognizes the role of overdeveloped countries in surpassing the ecological limits of our planet at the cost of wellbeing for billions of dispossessed people within and between countries. Cuba's circumstances during and following the Special Period exemplify both sides of the degrowth scenario, as well as demonstrating policy and grassroots …

Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms May 2018

Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms

United States National Park Service: Publications

Abstract

Prior to 2014, bat research at Devils Tower National Monument (DETO) focused on bats present during the summer months. Biologists at DETO assumed local bats were strictly summer residents due to the presumed lack of typical habitat features associated with bat hibernation, such as caves and mines. This lack of traditional hibernacula features at DETO discouraged staff and research cooperators from studying winter bat populations. Despite the earlier assumption that bats were unlikely to hibernate on the monument, DETO documented significant winter bat activity through passive winter acoustic monitoring. This study is the first study at DETO that documents …


What Is It Like To Become A Bat? Heterogeneities In An Age Of Extinction, Stephanie Erev May 2018

What Is It Like To Become A Bat? Heterogeneities In An Age Of Extinction, Stephanie Erev

Political Science Faculty Publications and Presentations

In his celebrated 1974 essay “What Is It Like to Be a Bat?,” Thomas Nagel stages a human-bat encounter to illustrate and support his claim that “subjective experience” is irreducible to “objective fact”: because Nagel cannot experience the world as a bat does, he will never know what it is like to be one. In Nagel’s account, heterogeneity is figured negatively— as a failure or lack of resemblance—and functions to constrain his knowledge of bats. Today, as white-nose syndrome threatens bat populations across North America, might figuring heterogeneity positively, as a condition of creativity, open up new modes of receptivity …

Killing Martin County : Resiliency In A Central Appalachian Community., David Adam Sizemore May 2018

Killing Martin County : Resiliency In A Central Appalachian Community., David Adam Sizemore

Electronic Theses and Dissertations

Environmental stressors, anything that poses a threat to human and environmental health, are disproportionately located in marginalized communities. Coal extraction companies produce and concentrate environmental stressors in Central Appalachia, a sub-region of Appalachia with high poverty rates and economic hardship. Through destructive coal extraction methods, the coal industry has jeopardized Central Appalachian health and environmental quality. The coal industry’s power to cause destruction in Central Appalachia is a product of historical strategic initiatives. Since the late 1800s, the coal industry has forcefully altered the culture and ideology of Central Appalachians and developed relationships with local, state, and federal policymakers to …


There Is Water In The World For Us : The Environmental Theories Of Alice Walker., Janae Lewis Hall May 2018

There Is Water In The World For Us : The Environmental Theories Of Alice Walker., Janae Lewis Hall

Electronic Theses and Dissertations

The emergence of African-American Environmental thought responds to the ongoing erasure of Black experiences and their perspectives on nature. Mainstream environmentalism maintains a legacy of perceived innocence and incorruptibility towards the land, while Black Environmentalism demonstrates the limitations of that ideology. Limitations include the erasure of history in regards to stealing land from Indigenous people, the brutality of slavery, legalized lynching, forced removal from the land, exploitation in sharecropping, destruction of sacred lands, heavy pollution in urban centers, and harmful environmental policies. For Black and Indigenous peoples, it is impossible to view American soil as innocent. This project surveyed the …

Merging Subsistence Perspective And Buen Vivir: An Alternative To Damming The Mekong, Aaron B. Eisenberg May 2018

Merging Subsistence Perspective And Buen Vivir: An Alternative To Damming The Mekong, Aaron B. Eisenberg

Dissertations, Theses, and Capstone Projects

This paper will examine the planned development on the Mekong by looking at the historical, political, and economic reasons why largescale hydroelectric dams are now being pushed upon the river. It will then critique the international state sovereignty system focusing directly on the Mekong River Commission and ASEAN (Association of Southeast Asian Nations) for their inabilities to mitigate environmental impact while pursuing development. I analyze how the “global city” discourse cannot rationally be applied to Southeast Asia and how the urban-rural divide in Southeast Asia creates only greater problems as dam production on the Mekong accelerates. I propose an alternative …

Full Circle: Building A Local Economy Through Pollinator Enterprises In The Food System, Catherine M. Demets May 2018

Full Circle: Building A Local Economy Through Pollinator Enterprises In The Food System, Catherine M. Demets

Graduate Student Portfolios, Professional Papers, and Capstone Projects

As the alternative food movement gains traction in mainstream American society, it is essential to document how enterprises in the movement are building robust local economies. As Eric Holt-Giménez (2010: 1) points out, the movement “has successfully shone the spotlight on hunger and food access in the US, created a drive for more local food, and gotten better policy from the federal to the local level,” yet no assurance exists that our society’s interest in food issues is not a passing fad. Rather, we should ask: “how do we turn initial reforms into lasting food system transformation?” (Holt-Giménez 2010: 1). …


Estimation Of Leachate Generated From Zimbabwe's Municipal Solid Wastes (Msw) Landfills Using A Simple Stochastic Water Balance Model, Andile B. Maqhuzu, Kunio Yoshikawa, Fumitake Takahashi May 2018

Estimation Of Leachate Generated From Zimbabwe's Municipal Solid Wastes (Msw) Landfills Using A Simple Stochastic Water Balance Model, Andile B. Maqhuzu, Kunio Yoshikawa, Fumitake Takahashi

Applied Environmental Research

Landfilling remains the predominant component in the waste management hierarchy of most developing nations. The adoption of emerging waste management technologies and the use of recycling or composting is still in its infancy. Among several inadequacies of current waste management practices in Zimbabwe is the absence of sanitary disposal of municipal solid waste (MSW) in landfills. As a result, the leachate generation rate and leachate characteristics are not routinely monitored. Such information is essential when assessing the impact of leachate on ground and surface water or a facility to which the leachate can be conveyed. Indiscriminate disposal of MSW at …
