Female Anti-Heroes In Contemporary Literature, Film, And Television, Sara A. Amato

Masters Theses

The anti-hero character has steadily become more popular in contemporary literature, film, and television. Part of this popularity is due to the character's appeal to the audience. This character type often commits acts that challenge the regulations of society. These acts, however, can become wish fulfillment for some audience members, making the acts of the character a vicarious experience as well as making the character more relatable because of the character's flawed nature.

This study will trace some of the evolution of the female anti-hero by discussing an ancestral character of the female anti-hero—Hester Prynne the protagonist of Nathanial Hawthorne's …

Assessing The Feasibility Of Wastewater Effluent As A Nutrient Source For Algae In The Context Of Biofuel Production, Justin Ryan Dore

Masters Theses

Algae have the potential to support the production of biodiesel due to their ability to produce large volumes of oils in relatively small footprints. However, algae production for biodiesel is hampered by the expenses associated with water and nutrients required for sufficient growth. A possible source of inexpensive and nutrient-rich water is the effluent of traditional wastewater treatment facilities. If wastewater effluent can support algae growth, the added benefit of reducing high nutrient loads to natural water systems can be realized.

Modeling The "Gravity" Of Foreign Aid: A Dyadic Panel Analysis On The Impact Of Bilateral Aid Commitments On Bilateral Immigration From 1994 To 2011, Miles D. Williams

Masters Theses

While research shows policymakers increase bilateral foreign aid commitments in response to an increase in bilateral immigration, supposedly as a means for reducing the demand for immigration, the effectiveness of this strategy is given only passing consideration in the literature. Many doubt this approach's success, but little effort has been made to empirically justify this doubt. This paper attempts to fill this gap in the literature and proposes a novel hypothesis. It is argued here that aid, more than simply failing to promote development quickly enough to reduce the demand for immigration, functions as a signal of donor wealth. When …

Behavioral Patterns Of The Cannibalism And Sexual Taboos, Kayla R. Rice

Masters Theses

Previous research has suggested that there may be a connection between the cannibalism taboo and sexual attraction. Specifically, it appears that when forced to choose someone to cannibalize, people choose victims in a pattern that mimics who they would choose to be sexually intimate with. To confirm and explore this relationship, the current study measured sexual orientation and examined whether participants' preferences in who to cannibalize if forced reflected their desired sexual partner. Participants recruited from Amazon Turk responded to forced pair choices regarding either desired sexual partner or cannibalism victims. Targets included all combinations of three variables: Physical Appearance …
