Characterization Of Carbon Nanotube/Polystyrene Composites Prepared Via Microwave-Induced Polymerization, Hubert Agamasu

College of Graduate Studies: Theses & Dissertations

Carbon nanotubes (CNTs), with their excellent mechanical properties, are well suited to the production of composites with good strength-to-weight ratio. However, the use of nanotubes as reinforcement is hampered by the lack of interaction between their inert surfaces and matrices. This, coupled with the van der Waal’s interactions between individual nanotubes, leads to agglomeration of CNTs in media. Functionalization is an efficient means to disperse nanotubes as well as increase their reactivity. The irradiation of CNTs with microwaves generates instantaneous, localized heating, being used in this work to trigger the rapid, thermal, free radical polymerization of styrene. Under microwaves, olefin-functionalized …

Their Country: Black Women, Three Chords, And The Truth, Dmetri J. Smith

College of Graduate Studies: Theses & Dissertations

ABSTRACT

Country music has long overlooked and at times outright erased the contributions of people of African descent. The past and present contributions of Black women are particularly ignored. Country music— a racially contested space centered in Nashville, Tennessee— is imbued with themes referencing the “good ole days” that were dangerous times for anyone who was not White, male, cisgender, and heterosexual. The genre has only become slightly more welcoming to those who are not part of the dominant class. And yet, there are Black women who feel called to use country music as their storytelling medium. My research shows …

Investigating Division Quest: A Text-Based Adventure Narrative Game For Overcoming Difficulties Of Mitosis Learning, Amanda G. Conner

College of Graduate Studies: Theses & Dissertations

Mitosis learning is a source of struggle for many introductory biology students. Much of this difficulty stems from an overwhelming amount of terminology and moving pieces as well as the abstract nature of cellular processes. Game-based learning (GBL) has been used in other contexts to reduce cognitive load and provide relatable experiences upon which students can construct their mental models. However, commercial GBL is often expensive and difficult to align with individual instructor teaching preferences and learning objectives. In this study, we use a mixed methods approach to explore the use of a GBL tool made in Twine to overcome …

Numerical Analysis Of A Novel Elastohydrodynamic Seal For Supercritical Co2 Power Cycles With Experimental Verification, Ali Akbor Topu

College of Graduate Studies: Theses & Dissertations

Masculine Vs. Feminine Women: Verdict, Blame, And Punishment Outcomes In The Legal System, Alaina Helmerichs

College of Graduate Studies: Theses & Dissertations

It is commonly recognized that sentencing disparities exist between men and women who are accused of the same crime—with men often receiving harsher judgements than women. However, research explaining why this disparity exists is incomplete. Research suggests that higher levels of facial masculinity in men is tied to higher levels of criminality (Estrada-Reynolds et al., 2017); however, little research looks at this pattern amongst female defendants. The current study investigated whether the gendered appearance (masculine vs. feminine) of female defendants in different types of cases (child negligence vs. medical malpractice) affects mock jurors’ judgments about verdict, punishment, and internal blame …

Mathematical Modeling Of Coupled Heat And Mass Transfer In Metal-Hydride Hydrogen Storage Systems, Muhammad Hasnain

College of Graduate Studies: Theses & Dissertations

As a promising clean energy carrier hydrogen has recently gained significant interest, but its efficient and safe storage is a major challenge. Compared to the gaseous state and liquid state, metal hydrides (MH) offer a potentially more effective storage approach for hydrogen. However, the main challenge in this approach is the low thermal conductivity of the MH bed that leads to low heat transfer and ultimately to higher charging and discharging times. The purpose of this work is to develop an in-house comprehensive heat and mass transfer model for hydrogen sorption in MH reactors to simulate the dynamic behavior of …

Development Of A Measure Assessing Adolescent Aggression: The Aggressive Behavior Risk Assessment- Adolescent- Parent Report (Abra-A-Pr), Katherine Fallon

College of Graduate Studies: Theses & Dissertations

Although parent-report scales for general behavioral difficulties and aggression (e.g., verbal and physical aggression) exist, there are currently no measures assessing sexual behaviors in this context. Commonly, parent-report measures provide a few items relevant to behavioral aggression, and items encompassing sexually aggressive behaviors are frequently vague and non-specific in the actions being committed by the adolescent. The primary purpose of this project was to develop a comprehensive and multifaceted parent-report measure for aggressive behavior in adolescents. Three separate studies were conducted to evaluate the psychometric properties of the measure. Exploratory (EFA) and confirmatory factor analysis (CFA) were used to investigate …

Using Natural Language Processing To Understand The Lived Experiences Of People Identifying With Adhd: What Themes Emerge In Social Media Posts?, Gabby C. Scalzo

Theses and Dissertations

Compared to the amount of research conducted on how to identify and understand children with Attention-Deficit Hyperactivity Disorder (ADHD), there has been relatively little work done to understand the lived experiences of adults with ADHD. Increased understanding of how adults with ADHD conceptualize themselves in the context of their diagnosis would help clinical experts tailor research and treatments to better serve these communities. However, there are several barriers towards conducting high-quality qualitative research, including time- and labor-intensity. This study, informed by qualitative research traditions, used innovative data sources (i.e., social media) and analytic techniques (i.e., machine learning) to reduce these …

Sense Make Before Book, Bradley Sinanan

Theses and Dissertations

“Sense Make Before Book” is an Indo-Caribbean turn of phrase which refers to common sense being more important than book smarts. My sister sent me a post the other day on Instagram of an Trinidadian woman using this phrase, saying it was one of Indo-Caribbean origin. I was interested and asked my mom about it. My mom says that when she was younger my grandpa said it often around their house in Princes Town, Trinidad and Tobago. This adage feels charged thinking about the history of indenture and its effects on the Indo-Caribbean diaspora.

The written word of archival history …

Beyond The Veil: Hijabi Superheroes And The Power Of Representation, Moom Thahinah Ms

Theses and Dissertations

As a Hijabi woman, I am often misrepresented by stereotypical narratives in Western media that obscure my individuality and agency. My thesis addresses the misrepresentation of Hijabi women, challenges audience perceptions, and empowers Hijabi women to confront these narratives.

Informed by design and media discourse, I developed a narrative and a Hijabi superhero character appropriating tropes of Western comic books. The resulting research combines two outcomes: a print-based narrative and a transformative garment. Print media is used to address the lack of Hijabi representation in Western comics while showcasing the character’s ability to combat discrimination. Derived from the comic format, …

A Walk In The Woods, Caitlin Mclean

Theses and Dissertations

A connection with nature fosters increased appreciation, admiration, and responsibility toward the natural environment, thus encouraging the mindful use of its resources and preservation of both species and their habitats. Defined by Mayer and Frantz (2004) as an “experiential sense of oneness with the natural world”, this connection is more important now than ever in this highly digital era. Studies indicate that limited exposure to nature can negatively impact the activation of neural pathways associated with pro-environmental attitudes and behaviors (Chawla, 2020), while further research shows that engagement with the outdoors during childhood as a significant life experience (Chawla, 1998), …

"I Call Them Supermoms": Therapists' Reflections On The Impact Of Youth Sexual Offending On Latina Mothers, Mauricio P. Yabar

Theses and Dissertations

Families of youth who have sexually offended often suffer significant collateral consequences following the discovery of the sexual offense. Samples in research with these families disproportionately consist of mothers and other female parental figures. This is rarely acknowledged in the literature, and the experiences of these mothers have not been explicitly examined. In addition, research on the experiences of these families has largely ignored factors related to race and ethnicity. This is a significant oversight considering the prevalence of systemic racism and discrimination in the United States, particularly in the systems with which these families must interact (e.g., juvenile justice …
