Temporal Discounting And Sustainable Behaviors, Natalia Piskorski

Theses and Dissertations

An experimental study was conducted (N = 175) to test for differences between thinking about the future and the present when it came to sustainable behavior and attitudes. Previous studies show temporal discounting can be overcome at least in the short term to alter current behaviors; however, there is a gap in the literature in regards to sustainable behaviors. This study used similar techniques to determine whether environmentally protective behavior can be altered by having an individual imagine themselves in the future. Participants were randomly assigned to one of three groups, a current other, current self, or a future-self group. …

Environmental Governance For Whom? Examining The Political, Institutional, Fiscal, And Legal Determinants Of State Environmental Agency Budget Policy In The Us, Andrew R. Duggan

Theses and Dissertations

Budgets are a prospective tool of governance, and appropriations are a planning vehicle reflecting: bureaucracies’ values, complex interactions, collective preferences, political influences, and available resources. Research spanning 30 years finds that environmental pollution is a key determinant of environmental budgets in the US, though myriad factors, actors, and subsystems are important to consider. Due to federalism and devolution of responsibilities and authorities, environmental governance falls largely to the states. While the dynamics that shape state environmental budget policy have received scholarly interest, theoretically-driven examinations of environmental appropriations remain limited within the public budgeting and environmental policy literature.

Design Hub: Activating Community By Design, Ed Williams

Theses and Dissertations

MOTIVATION

At the turn of the century, Robert Putnam (2000, 27) wrote “...a powerful tide bore Americans into ever deeper engagement in the life of their communities, but a few decades ago that tide reversed and we were overtaken by a treacherous rip current.” Putnam is describing a loss of “social capital” throughout American society. Research suggests that many of our contemporary issues are the result of a decline in “social capital,” or “community.”

This pervasive lack of community is thought to be detrimental to “educational performance, safe neighborhoods, equitable tax collection, democratic responsiveness, everyday honesty, and even our health …

Aesthetic Perception Of Urban Spaces: New York, Timur Pozhidaev

Theses and Dissertations

Aesthetic perception is an important field of interest in many aspects of everyday human life. It affects individual and social unconscious behavior and is strongly related to the decision-making processes in the human mind. The current study can serve as an important prototype for planning purposes and social and environmental justice among the regional units of New York City. With the current scientific sphere lacking a comprehensive methodology for assessing social superstructure, an aesthetic framework has the potential for success in evaluating the aspects of sustainable and resilient urban development.

Exploring Local Environmental Factors Influencing Geographic Distribution Of Black-Legged Tick Questing Activity, Chong Di

Theses and Dissertations

The deer tick (Ixodes scapularis or I. scapularis), also known as the black-legged tick, is the primary vector that transmits Lyme Disease (LD) in Northeastern United States. To contain the geographic expansion of Lyme disease ticks across the US in recent decades, ecological studies have been conducted to understand the biotic and abiotic environmental factors affecting tick activity. We observed in preliminary surveys that the tick host-seeking activity varies across small local areas. The primary objective of this project is to identify the environmental factors that impact deer tick questing activities at the micro-geographic scale. From 2017-2018, we …

Climatic Variables Are Strong Predictors Of Allonursing And Communal Nesting In Primates, Alexandra Louppova

Theses and Dissertations

Allomaternal care (AMC) is widespread throughout the primate order, previous studies have focused on benefits and costs to individuals. However, our understanding of environmental impacts on AMC behaviors in primates is still limited. Our study examines how ecology and environmental factors can predict certain AMC behaviors more than others.

Climate change and archaeology are currently intertwined, as more and more archaeologists around the world must deal with the effects it causes on the sites they work on. Threatened cultural resource sites are being swept away at alarming rates, and excavation projects are becoming more and more like salvage digs.

Environmental Links To Ectopic Kidney Diseases, Firas Alhasson

Theses and Dissertations

Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease in the western culture and worldwide. Its morbidity has been raising and it has become a burden on the public health. NAFLD is associated with other metabolic diseases such as Diabetic Mellitus and hypertension. NAFLD is a wide spectrum of symptoms, from an accumulation of fat in the liver (cirrhosis) to production of scar tissue (Fibrosis). The liver along with other distal organs such as the kidney and cardiovascular system can be damaged as ectopic manifestations of NAFLD. Contamination of drinking water with Cyanobacterium toxin (Microcystin) and water disinfection …

Exploratory Modeling Of Environmental And Anthropogenic Impacts On Mercury In Fish Tissue For Select Watersheds In South Carolina, Julia Mcguire

Theses and Dissertations

Fish tissue from various sampling locations in South Carolina rivers has shown elevated levels of mercury (Hg). A number of variables may impact this Hg in fish tissue and this study evaluated the impact of these variables using a predictive model. Over 341 variables were assembled from 6 different databases describing land use, water chemistry, point source pollutants, watershed characteristics and more. One dataset describes the location of historical gold mines throughout the sample site, which have been shown to increase Hg in fish tissue in other locations. The variables were assembled in ArcGIS to evaluate variable significance and to …

Estimating Stormwater Runoff For Community Gardens In New York City, Mara Gittleman

While much of the literature cites community gardens as providing urban ecosystem services, there is very little research quantifying these benefits. This thesis compares the stormwater runoff rates of urban vacant lots, community gardens, and residential developments in New York City and evaluates community gardens as green infrastructure.

Dispersal: A Multidisciplinary Investigation Of Plant Life, Alexandra E. Arzt

Theses and Dissertations

Using plants as a basis for exploring the interstices between the human and nonhuman, this thesis investigates ideas of awareness, intelligence, deep time, animism, and the fluctuating human perception of the agency of Nature. It outlines environmental art practices since the 1950s involving vegetal life. In addition, the paper provides a critical analysis of plant perception of Jakob von Uexküll’s work and theories of vital materialism and “critical plant studies” while noting recent studies in plant neurobiology. In my work, plants become active participants via their movement, seeding, and smell. This study takes the form of imitation, purposeful symbiosis, anthropomorphism, …

Expanding Eco-Visualization: Sculpting Corn Production, Jennifer E. Figg

Theses and Dissertations

This dissertation expands upon the definition of eco-visualization artwork. EV was originally defined in 2006 by Tiffany Holmes as a way to display the real time consumption statistics of key environmental resources for the goal of promoting ecological literacy. I assert that the final forms of EV artworks are not necessarily dependent on technology, and can differ in terms of media used, in that they can be sculptural, video-based, or static two-dimensional forms that communicate interpreted environmental information. There are two main categories of EV: one that is predominantly screen-based and another that employs a variety of modes of representation …

Characterizing Wetland Hydrology, Chemistry, And Soils For An Endemic Crayfish, The Piedmont Blue Burrower, Jess H. Gilmer Ii

Theses and Dissertations

Anthropogenic alteration of Earth's ecosystems has pushed global biodiversity into a state of crisis. Freshwater species have been particularly vulnerable, with crayfish ranking as the second most imperiled taxonomic group in North America. Primary burrowers represent only 15% of crayfish species in North America; however, they constitute 32% of imperiled crayfish. Despite their conservation importance, little is known about the ecology of burrowing crayfish. To advance our knowledge about the habitat characteristics of burrowing crayfish, groundwater hydrology, water chemistry, and soil properties were assessed to determine their importance for the state-listed endangered, primary burrower Cambarns harti. Groundwater hydrology and …

Determining An Optimum Cropping Pattern For Egypt, Loujaina M. El Sayed

Theses and Dissertations

Agriculture is considered to be the major economic activity in Egypt despite the government policies that favored other sectors since the second half of the 20^th century. However, Egypt currently faces a food security challenge that stems from the increasing demand for food in light of huge population growth and the inability of the agricultural sector to fulfill the abovementioned increasing demand.

This research focuses on the vertical expansion of the agricultural sector through attempting to determine the optimum cropping mix for Egypt in the year 2017. A fuzzy goal programming (FGP) approach for optimal land allocation is utilized. …

A Raster-Based Gis Analysis Of The Cumulative Impacts Of Humans And Beaver On Wetland Area And Types In The Chickahominy River Watershed (Virginia, Usa) From 1953 To 1994, Alexandra Dunya Syphard

Theses and Dissertations

Despite increased recognition of wetland functions and values, wetland loss and degradation continues in the United States. Digital wetlands and uplands coverages were analyzed to compare the cumulative impacts of humans and beaver (Castor canadensis) on wetland types in the Chickahominy River watershed (Virginia, USA) from 1953 to 1994. A vector-based approach was used for data manipulation, and a raster-based approach was chosen to analyze geographic change over time. Study findings indicated that anthropogenic activities were responsible for both wetland loss and gain in the watershed, and beavers substantially influenced shifting between wetland types. Wetland area increased 4% over 41 …
