Barriers Teaching Environmental Justice Education, Jodi Devonshire

Dissertations

The idea of freedom in education has its roots in the social justice movements of the 1950s and 60s. Civil rights groups coalesced independently of other marginalized groups and movements of its time. While similar in nature, environmentalism and civil rights issues rarely crossed paths. As environmentalism made its way into science education and curriculum, social justice issues were restricted to historical perspectives in education. This research initially sought to create an understanding of purpose driven, social justice conscious, Environmental Education as it is related to marginalized learners and identify the barriers of creating and implementing culturally relevant environmental education …

Cognitive Ecology Of Color Vision In Orchid Bees, Andreia Queiroz Santos A Figueiredo

Dissertations

Animals interact with their environment and acquire information from it. Information can be processed by their sensory systems and influence behavior, often mediated through mechanisms of decision-making and learning.

My research aimed to understand the role of color vision in a tropical pollinator, the orchid bee Euglossa dilemma. Chapter 1 is a review exploring pollination through the lens of prepared learning. Prepared learning proposes that animals learn some associations better than others due to an evolved match with the environment. I …

White Voters And Minority Animus In The Era Of Trump, Zachary Schwartz

Dissertations

Overt and blatant racism of the type that was once used to justify Jim Crow laws and other forms of de facto segregation against Blacks has largely been forced into the margins of society. However, the reduction of overt racism that casts whites as biologically superior to Blacks can be easily confused with a reduction of racism in totality. The election and continued popularity of Donald Trump demonstrates that the conversation on race in the United States needs much more analysis. On multiple occasions during his campaign and presidency, Trump made inflammatory remarks on race and immigration, and yet suffered …

The Impact Of Target Audit Quality On The Likelihood Of Future Goodwill Impairment, Elizabeth Boyle

Dissertations

US Generally Accepted Accounting Principles (GAAP) require that in an acquisition, the purchaser must record a premium when the purchase price exceeds the fair value of the target’s identifiable net assets (both tangible and intangible). This premium lives on the balance sheet as an intangible asset called goodwill. Goodwill has an indefinite life, but over time it may become impaired due to overpayment of the original acquisition, unrealized synergies, changes in the business, legal issues, etc., and as a result, require a write-down. This impairment not only impacts the acquirer’s balance sheet but can also impact the market value of …

Semi-Empirical Modeling Of Liquid Carbon's Containerless Solidification, Philip Chrostoski

Dissertations

Elemental carbon has important structural diversity, ranging from nanotubes through graphite to diamond. Previous studies of micron-size core/rim carbon spheres extracted from primitive meteorites suggest they formed around such stars via the solidification of condensed carbon-vapor droplets, followed by gas-to-solid carbon coating to form the graphite rims. Similar core/rim particles result from the slow cooling of carbon vapor in the lab. The long-range carbon bond-order potential was used to computationally study liquid-like carbon in (1.8 g/𝐜𝐦𝟑) periodic boundary (tiled-cube supercell) and containerless (isolated cluster) settings. Relaxations via conjugate-gradient and simulatedannealing nucleation and growth simulations using molecular dynamics were done to …

Schools On The Frontlines Of Governance: How The Convergence Of Criminal Justice And Education Shapes Adolescent Perceptions And Behavior, Jennifer O'Neill

Dissertations

Theories of legal socialization posit that individuals’ interactions with both nonlegal (e.g., teachers) and legal (e.g., police officers) authorities impact our broader orientation towards governance our compliance with rules and laws. Examining the process of legal socialization in adolescents is critical for understanding individuals’ relationships with major institutions of social control, and further, predicting delinquency. Extant literature tends to consider legal socialization in the school and in interactions with the police as distinct processes related to offending, neglecting the potential influence of school contextual factors; and yet, because the incorporation of carceral features (e.g., exclusionary discipline, restrictive security, and enhanced …
