Constraining The Timing And Degree Of Metamorphism In The Echo Canyon Region: Evidence For A Cryptic Contact Aureole, Keanu Montañez

Graduate Research Theses & Dissertations

Local occurrences of andalusite and kyanite in Echo Canyon, within the Funeral Mountains metamorphic corecomplex, overprint chlorite-grade phyllites and reveal the presence of a hidden pluton and its contact aureole. Phase equilibria models indicate minimum conditions of 0.45 GPa and 535 °C in the highest-grade zone of the aureole, with significantly higher temperatures than previously estimated for the area. This study applied phase equilibria pressure-temperature modeling, petrography, Raman spectroscopy, and ⁴⁰Ar/³⁹Ar geochronology on muscovite to characterize this anomalous metamorphism and to place it within a revised tectonic framework. Two potentially coeval prograde metamorphic events have been recognized based on petrographic …

The Roles Of Parental Self-Efficacy And Educational Instrumental Support In Predicting Academic Motivation And Reading Skills Among Students With Adhd Symptoms, Saheli Anil

Graduate Research Theses & Dissertations

Attention-deficit/Hyperactivity disorder (ADHD) symptoms can manifest early in a child's life and can result in detrimental outcomes in education if left unaddressed. Often, children with ADHD symptoms tend to experience low levels of academic motivation (Smith & Langberg, 2018; Volpe et al., 2006). However, previous research has established that parents with high levels of self-efficacy for helping their children academically and parental educational instrumental support tend to predict greater educational outcomes. The current study examined whether both mothers’ and fathers’ support and mothers’ self-efficacy influenced the associations between child ADHD symptoms, academic motivation, and reading in a sample of 181 …

Graduate Research Theses & Dissertations

To understand the mechanism by which anti-microbial peptide penetrates biological membranes,the study uses artificial supported lipid bilayers (SLBs) deposited on solid substrates. These bilayers were prepared from a lipid mixture of 1,2-dimyristoyl-sn-glycero-3- phosphocholine (DMPC)and 1,2-dimyristoyl-sn-glycero-3-phospho-(1’-rac-glycerol (DMPG) in a 10:1 molar ratio and were incubated both with and without indolicidin. Additionally, bilayers were studied after incubation with a labeled form of indolicidin, which involved attaching a 1.8 nm diameter gold nanoparticle to the peptide’s terminal arginine group.

X-ray reflectivity (XRR) was employed to identify structural differences between SLBsincubated with indolicidin and those without it. The introduction of gold labeling facilitated the …

Meaningful Legislative Conflict: The Role Of Party Competition, Nader Omar Alghoul

Graduate Research Theses & Dissertations

This dissertation explores the influence of legislative conflict, defined by party polarization, relational animosities, and majority size, on legislative productivity in the U.S. Congress. While prior studies have focused on party polarization, divided government, and relational conflict, this research broadens the analysis by incorporating majority size as a key determinant of legislative accomplishment. The research will affirm that moderate polarization sharpens policy debates and enhances productivity, while extreme polarization, particularly when combined with significant relational conflict, results in legislative gridlock. Importantly, this research adds majority size to the amalgam of conflict and uncovers a curvilinear pattern: modest majorities improve legislative …

It's Not The Fault Of The Parrot, But Of The One Who Teaches Him To Talk: Understanding Identities And Relationships Of An Educational Ngo In Guatemala, Brittany Rebecca Blomquist

Graduate Research Theses & Dissertations

Guatemala is an economically poor country, with a rich culture that makes it a destination for foreign assistance through non-governmental agencies (NGOs) and tourism. The history of conflict and foreign economic development within the country has created a dichotomy of identities, divided across economic wealth, ethnicity, and urban/rural landscapes. NGOs, their presence as transnational actors, and their organizational identities augment the identities present within the spaces in which NGOs work. Additionally, these identities are fluid and relational. I argue that the identities and relationships that form within the NGO space are reflective of NGO work and development structures. The identities …

The Role Of Metaperceptions In Mindset Formation From Performance Feedback, Audra Paige Jensen

Graduate Research Theses & Dissertations

This dissertation investigated the cognitions that recipients of feedback had about their evaluators, and how that impacted achievement choices. Specifically, it aimed to analyze the role that metaperceptions of developability played in the mindset formation process following feedback. Although mindsets form based on different ways feedback is framed, the exact method that leads from feedback to mindset formation is not clear. Prior research has pointed to a meta-lay theory as the mediating component that leads from feedback framing to mindset. However, how the perception of an evaluator’s mindset would lead to changes in a recipient’s own beliefs was still unclear. …

Moral Bonds, Modern Subjects: Pecúlio, Property Rights, And The Abolition Of Slavery In Rio De Janeiro, 1822-1888, Alexander Joseph Lundberg

Graduate Research Theses & Dissertations

This dissertation examines the role of enslaved persons’ savings for self-purchase manumission (pecúlio) within the process of gradual abolition in the province of Rio de Janeiro, Brazil. Article IV of the 1871 Rio Branco Law granted enslaved persons in Brazil the legal ownership of their savings and, with those savings, the right to purchase freedom. Article IV supplemented the “free womb” provision of the Rio Branco Law, which declared that all children henceforth born to enslaved mothers were free. In the Brazilian Parliament, the law’s proponents argued that the savings provision would help reduce the enslaved population by codifying long-standing …

Hidden Wounds And Secret Scars: The Post-World War Ii Western As A Cinema Of Trauma, Maggie Sue Scanlan

Graduate Research Theses & Dissertations

In this project, I consider the post-WWII Western film as a site that represents and navigates war traumatized American masculinity. Through a discussion of the significance of the Western as a national myth that speaks directly to American masculinity and nation-building through individual violence, I situate the genre as an ideal vehicle to reframe war traumatized masculinity and analyze seven Westerns through a threefold analysis: metaphoric (a cinema of trauma), psychoanalytic (the traumatic gaze), and therapeutic (recovery and reintegration). In Chapter One, I track anxieties and preoccupations signaling the cultural concern with war trauma in genres more routinely associated with …

The Impact Of Culturally Responsive Classroom Management Self Efficacy And Implicit Biases On Teachers’ Perceptions Of Student And Their Behaviors, Andrew Edward William Slany

Graduate Research Theses & Dissertations

Teachers’ perceptions of student behaviors influences the daily decisions that are made within the classroom setting. Specifically, teachers’ perceptions influence the decision-making process related to how teachers manage student problem behaviors and teachers’ responses to these behaviors. Research has found that teachers’ classroom management self-efficacy and student infraction history can impact teachers’ perceptions of student behaviors. Additionally, teachers’ perceptions of students and their behaviors can be influenced by implicit biases. However, there still exists a gap within the literature that does not fully explain why these teacher judgements occur. The current study examines whether teachers’ culturally responsive classroom management self-efficacy …

The Impacts Of Trust In The Time Of Covid-19, Hannah Temes

Graduate Research Theses & Dissertations

Over 350,000 Americans died from COVID-19 in 2020, the first year of the pandemic. Federal health institutions such as the Center for Disease Control and Prevention (CDC) and the Department of Human Health Services (DHHS) established guidelines for the public to follow during the pandemic. However, trust in these institutions varied resulting in differing public response —some followed the COVID protocols while others did not. It has been argued that when someone’s self-interest is at risk, they need to trust the government to take care of them. During the COVID-19 pandemic, a time when public health and self-interest were intertwined, …

"I Know You're Just Teasing Me!": Investigating 5th Grade Students' And Teachers' Understanding Of Prosocial Teasing, Ourja .

Graduate Research Theses & Dissertations

Children engage in prosocial teasing which is an ambiguous, positive, and humorous social interaction involving the use of intentional provocation and off-record markers to form meaningful relationships and resolve conflicts (Keltner et al., 2001). While research has indicated a significant prevalence of prosocial teasing use among children, limited studies have explored the levels of prosocial teasing use among elementary school students and teachers' ratings of that use (Barnett et al., 2004; Smith et al., 2009). This study aimed at refining an existing child behavior scale to develop a subscale that accurately measured and represented prosocial teasing in elementary school children. …
