Y'All Eat: Foodways, Performative Regional Identity, And The South In The Twenty-First Century, Kirsten Schofield
Electronic Theses and Dissertations
"Y'all Eat: Foodways, Performative Regional Identity, and the South in the Twenty-first Century" examines the ways in which iconic Southerners--Jim Beam and his ilk, Colonel Harland Sanders, and Paula Deen--create and sustain the hypercontemporary South. Because of their media exposure and place in the popular imagination, these characters force a specific kind of performance in both an intergroup and intragroup context. Close readings of individual appearances and selected portions of these characters' output help to shed light on how these identities are formed, upon what they rely for structure and support, and what this means for modern consumers around the …

An Analysis Of Ohio's Alternative Energy Portfolio Standard, Joshua A. Laufer
Honors Papers
I performed quantitative analyses and qualitative interpretation of energy policy data, energy production and consumption data, and political data. I collected data on state Renewable Portfolio Standards from the Database for State Incentives for Renewable Energy (DSIRE), energy production and consumption data for the 50 states and Washington D.C. from the Energy Information Agency (EIA), and 1992 presidential election data from the internet. I identify relationships that exist between these different types of variables, and where Ohio fits in the national context of existing energy patterns and policies. There are several conclusions found in the literature that are independently tested …

Potential Wolverine Habitat Vs. Winter Recreation. Conflict In Colorado!, Paul Quigley
Geography and the Environment: Graduate Student Capstones
The Global list of endangered species of flora and fauna is growing, with the most highly specialized species often at ‘critically endangered’ status. Managing these populations effectively involves numerous and varied organizations, conflicting motivations, arbitrary anthropogenic boundaries and often most importantly, data compilation and management. We are seeing many more reintroductions of locally extirpated species back into habitats of historical prevalence – and as extreme a method of conservation as this is, there is still a need for more extreme methods. High profile and highly specialized endangered species are often managed in a ‘crisis’ mode, where complex behaviors and interactions …

Transboundary Political Ecology In The Peru-Brazil Borderlands: Mapping Workshops, Geographic Information, And Socio-Environmental Impacts, David S. Salisbury, A. William Flores De Melo, Pedro Tipula Tipula
Geography and the Environment Faculty Publications
Development, resource, and settlement frontiers inspired by national policies and global demand continue to expand into the international boundary lands of Amazonia. National policies promote development and conservation projects on lands already inhabited and managed. Regional governments are increasingly frustrated by the inadequate and outdated geographic information available to solve overlapping claims and improve planning in sensitive border regions. The resulting combination of inappropriate policies, contested resources, and poor geographic information in the borderlands create impacts not only for national, regional, and local landscapes and livelihoods but also foreign relations due to transboundary effects. This article uses a transboundary political …

Dept. of Organisation & Professional Development Publications
This study explores the merits of the Electric Vehicle (EV) as an alternative mode of transportation in Ireland. The EV has been produced for many decades, but never in a mass production capacity. EVs do not require fossil fuels to power them. With fossil fuels being in short supply and as global climate change is deteriorating each year; the EV will help reduce Ireland’s dependence on depleting fossil fuel resources. This current study seeks to establish if the EV can be part of the solution to prevent further un-repairable damage to the environment. The findings of this current study, demonstrate …

Using Participatory Scenarios To Stimulate Social Learning For Collaborative Sustainable Development, Kris A. Johnson, Genya Dana, Nicholas R. Jordan, Kathy J. Draeger, Anne Kapuscinski
Dartmouth Scholarship
Interdependent human and biophysical systems are highly complex and behave in unpredictable and uncontrollable ways. Social and ecological challenges that emerge from this complexity often defy straightforward solutions, and efforts to address these problems will require not only scientific and technological capabilities but also learning and adaptation. Scenarios are a useful tool for grappling with the uncertainty and complexity of social-ecological challenges because they enable participants to build adaptive capacity through the contemplation of multiple future possibilities. Furthermore, scenarios provide a platform for social learning, which is critical to acting in the face of uncertain, complex, and conflict-laden problems. We …

How Milk Does The World Good: Vernacular Sustainability And Alternative Food Systems In Post-Socialist Europe, Diana Mincyte
Publications and Research
Scholarly debates on sustainable consumption have generally overlooked alternative agro-food networks in the economies outside of Western Europe and North America. Building on practice-based theories, this article focuses on informal raw milk markets in post-socialist Lithuania to examine how such alternative systems emerge and operate in the changing political, social, and economic contexts. It makes two contributions to the scholarship on sustainable consumption. In considering semi-subsistence practices and poverty-driven consumption, this article argues for a richer, more critical, and inclusive theory of sustainability that takes into consideration vernacular forms of exchange and approaches poor consumers as subjects of global history. …
