Methane Oxidation Potential Of Uncomposted Yard Waste As A Landfill Biocover, Gomathy Radhakrishna Iyer Dec 2018

Methane Oxidation Potential Of Uncomposted Yard Waste As A Landfill Biocover, Gomathy Radhakrishna Iyer

Civil Engineering Dissertations

Biocovers are widely used in landfills to oxidize emissions of the greenhouse gas methane. Biocovers used till date are fully or partially made of composts. Compost takes time and effort to create, and costs about $10 per cubic yard on an average. Even more importantly, however, production of compost, although theoretically an aerobic process, actually generates methane, from 3.2 to 362 kg CO2-equivalents per ton of wet waste composted, depending on the type of waste, whether open or enclosed composting technology is used, and other factors. To reduce the net greenhouse gas emissions from biocovers, this research explores the potential …

Italian American Literature And Food: A Match Made In The Kitchen A Handbook, Monica Marchi Dec 2018

Italian American Literature And Food: A Match Made In The Kitchen A Handbook, Monica Marchi

English Dissertations

Food is a recurrent theme in Italian American literature and authors have used it to highlight the importance of family, women, and the community at large and to teach about Italian customs to the U.S. public. Oftentimes, for the older Italian immigrants, food triggers fond memories of the Old country, while, for the younger generations, it might cause shame that leads to clashes with the older generations. Characters use food as a tool to express power and, later, status and to communicate. Food also defines relationships, gives an identity to the Italian immigrants on foreign soil, and allows them to …

Truth And Strength In Vulnerability: Using Topoanalysis To Reveal The Need For Expanding The Modernist Literary Canon, Misty Dawnmarie Falkenstein Dec 2018

Truth And Strength In Vulnerability: Using Topoanalysis To Reveal The Need For Expanding The Modernist Literary Canon, Misty Dawnmarie Falkenstein

English Theses

In the late nineteenth and early twentieth centuries, the public role of women shifted dramatically. Women asserted themselves in politics, education, and work in a way foreign to their Victorian predecessors. Although these “New Women” altered the gender landscape and set in motion a new path for women that would continue even into the twenty-first century, their writing still goes largely unnoticed in the current study of the Modernist literary canon. This project makes a case for expanding the current Modernist literary canon to include more of these women, especially women of disenfranchised racial, ethnic, cultural, and economic groups. Writers …

Society Does Not R-E-S-P-E-C-T Black Mothers: Historically Racialized Representations And Black Women’S Compromised Obstetrical Care, Ashleigh Riley Dec 2018

Society Does Not R-E-S-P-E-C-T Black Mothers: Historically Racialized Representations And Black Women’S Compromised Obstetrical Care, Ashleigh Riley

English Theses

This thesis explores the correlation between racialized representations of Black women with the disparities in the level of healthcare they receive and the resulting outcomes. I argue racialized representations of Black women throughout history and into the modern-era compromise Black women’s obstetrical care, affect their reproductive freedom, and contribute to their disproportionately higher maternal mortality rates. By citing pivotal historical events and the resulting racialized tropes from the antebellum, reconstruction, and civil rights time-periods, I identify the modern-era manifestations of those representations. Using theoretical lenses associated with Black Feminist Theory, Intersectionality, and Scripting, I analyze how historically racialized representations of …

Meming And Enthymeming: Persuasion In The Age Of Social Media, Taylor R. Parrish Dec 2018

Meming And Enthymeming: Persuasion In The Age Of Social Media, Taylor R. Parrish

English Theses

While rhetoric as a field of study has existed for several millennia, social media can prove to be a difficult medium to analyze rhetorically. This thesis examines some traditional elements of rhetoric, including the rhetorical triangle as well as the canons of rhetoric, and weaves them together with the narrative paradigm theory, as posited by Walter Fisher in his 1987 book Human Communication as Narration: Toward a Philosophy or Reason, Value, and Action. Together, rhetoric and the narrative paradigm provide some useful tools for analyzing the world of social media, helping users to more accurately ascertain the veracity of posting; …

A Staring Contest With The Self: Karl Ove Knausgaard, Linguistic Inquiry And Word Count, And Explanatory Style, Colton Tyler Royle

English Theses

Shame as an emotional response in the late 2010s has been discussed in both high and low sectors, from a high level of shame with social media use in high school classrooms, to the lack of shame by the president of the United States. My thesis addresses this question by analyzing Karl Ove Knausgaard’s two autobiographical works, My Struggle and his Seasonal Quartet. Readers, critics, and Knausgaard himself have described his work as a focus on the shameful moments of his life. Using positive psychology’s term “explanatory style,” coined by Martin E.P. Seligman, I do a structural reading of explicit …

Motivators Of Prostitution Desistance, Shawn Nicole Guy Dec 2018

Motivators Of Prostitution Desistance, Shawn Nicole Guy

Criminology & Criminal Justice Theses

The intent of this thesis was to determine the factors that lead to desistance from street prostitution in the form of motivators and how to shape recommendations to courts, social services, and policy-makers based off of identified themes. Additionally, various theories are discussed, supporting the presence of identified motivators and themes, that could be used by interventionsists as guiding principles when working on strategies for prostitution desistance modifications. Without isolating and stratifying motivators and themes, prostitutes who desire to desist may not receive appropiate treatments and interventions and may continue to recidivate with prostitution-related criminal charges. Statements obtained through qualitative …

Structural Safety Of Bridge Decks With Variable Rebar Cover, Prem Egade Dec 2018

Structural Safety Of Bridge Decks With Variable Rebar Cover, Prem Egade

Civil Engineering Theses

Construction defects are common and are difficult to avoid completely. This arises due to improper workmanship, inspection, drawing and specification. On bridge decks, achieving the desired cover is necessary since inadequacy can cause accelerated corrosion in steel and for the most part spalling and delamination which ultimately led to failure. Tolerance provided by different standards and specification also restrict the amount of rebar. So, construction is more focused on increasing cover undermining the loss of strength as consequence. The objective of this research is to check the safety of decks by analyzing bridges for reduction in capacity due to cover …
