Team Origins: Leveraging Network Utilization And Leadership To Explain Team Assembly, Pol Solanelles

Electronic Theses and Dissertations

Drawing from social networks and leadership perspectives, I advance our understanding of team assembly – which I define as the goal-motivated, multi-step, and iterative process by which two or more potential team members interact to organize into nascent teams via formal and/or informal influence. Across three essays, I aim to redirect the conversation from who will become part of a team to how individuals assemble teams, placing leaders assembling teams and potential team members at the forefront of this research.

In Essay 1, my interdisciplinary integrative conceptual review revealed four opportunities to clarify how people assemble teams. First, I use …

Investment Decisions Of Institutional Investors, Sunghan Bae

Electronic Theses and Dissertations

In the first essay, we investigate whether social preference affects institutional investors’ socially responsible investing (SRI) by examining US insurance firms. Prior literature suggests that investors value firms’ socially responsible endeavors and are willing to sacrifice financial gains when conducting SRI. We show that, on average, insurers allocate less weight to securities with high ESG (Environment, Social, and Governance) scores. However, a subset of insurers with high Corporate Social Responsibility (CSR) scores overweight high ESG securities. Moreover, we find that insurers with high CSR scores experience positive abnormal returns when they invest in high ESG stocks. This indicates that insurers …

Whole Genome Crispr-Cas9 Screens Identify Genes Contributing To Viral Entry And Phagocytosis, Md Saddam Hossain

Electronic Theses and Dissertations

CRISPR/Cas9 is a revolutionary technique for genome editing where Cas9 nucleases can be targeted to specific genomic sites by single-guide RNAs (sgRNAs) containing roughly 20-nucleotide sequences that are complementary to the target region. Double strand breaks created by Cas9 are repaired through non-homologous end-joining (NHEJ) in most cells, resulting in insertions and deletions leading to frame shift mutations in coding regions. Thus, the CRISPR-Cas9 system can be exploited for systematic evaluation of gene function relationships by whole genome screening. We also developed a CRISPR whole‐genome screen and counter‐screen strategy based on a pseudoviral platform that allowed identification of genes specific …

Strung together by one film, young women of the Asian diaspora mirror and maneuver each other, while playing out their performances of self with art as their arena.

More Than A Feeling: Materializing Sympathy In Nineteenth-Century American Literature, Kathleen Downes

Electronic Theses and Dissertations

“More than a Feeling: Materializing Sympathy in Nineteenth-Century American Literature” breaks from a long tradition of criticism that only considers the nineteenth-century belief that sympathy was a benevolent, voluntary, imaginative act of feeling that maintains moral rectitude through the identification of suffering with others. In this context, sympathy is primarily defined as identificatory sympathy. “More than a Feeling” expands the definition of sympathy in the nineteenth century as also something that could be atmospherically communicated, transmitting good or bad feeling, and thus affecting and infecting those around them. This other form of sympathy, which for this project I term “effluvial …

Mississippi's America: Late Southern Writing On National Themes, Jacob Fennell

Electronic Theses and Dissertations

This project examines three texts each from three Mississippi authors working today: Kiese Laymon, Jesmyn Ward, and Mary Miller. These authors’ literary constructions of their home state and the South as a whole serve as critical, political frames for the United States. As a result, their work is well-served by the questions and methodology of New Southern Studies, a field actively invested in conceptions of the U.S. South as nonexceptional and lodged within greater geopolitical contexts. Indeed, the original call for New Southern Studies from Houston A. Baker, Jr. and Dana Nelson speaks to a problem of a false national …

Race/Ethnicity And Gender Preferences In The Small Firm Exempt Offering Market, Mercer Bullard

Electronic Theses and Dissertations

Minority and female entrepreneurs who have sought to raise capital in private (exempt) securities offerings in the U.S. have encountered a market in which they are substantially underrepresented. The most relied on exemption, Regulation D (Reg D), generally requires that investors meet wealth requirements. Such “accredited” investors may seek investment opportunities in networks from which minorities and women are excluded or that are biased against them. In 2012, the Securities and Exchange Commission created a new crowdfunding exemption (Reg CF) that was intended to improve access to capital for such disadvantaged entrepreneurs. Reg CF generally allows anyone to invest and …

"Plural Aspects Of The Self": Naomi Long Madgett's Polyvocal Poetry And Black Feminisms, Morgan Leigh Mccomb

Electronic Theses and Dissertations

Even though Naomi Long Madgett’s poetic career spanned over 60 years; even though she was in writing groups and publication circles with some of the twentieth century’s most seminal African American poets; and even though her work has been extensively anthologized, Madgett’s literary career and legacy have yet to be examined as a critical matrix for understanding her as a foundational theorist, artist, and intellectual within Black feminisms. Though Madgett wrote and published during the historical beginnings of the development of Black feminist thought, her work is rarely discussed as essential for understanding and expanding critical and historical notions about …

Magnolia State Of Mind: Memory And Memorialisation In Mississippi, Cosmo Mcgee

Electronic Theses and Dissertations

This thesis explores the ways Mississippi has historically and contemporaneously crafted its collective memory through symbolism. Confederate memorial groups endeavoured to create a “Lost Cause” memory of the state’s Antebellum past, validating its White supremacist systems into the 1960s. With the violence of the Civil Rights era failing to stop integration, Mississippians would spend the next sixty years debating the best ways to represent the state’s history.

This work looks at three distinct manifestations of Mississippi’s memorial culture: the discussions around and changes to the state flag, the cultural and sporting atmosphere of the University of Mississippi (“Ole Miss”), and …

Spins And Kicks: An Analysis Of Dynamical Properties Of Compact Binaries Using Gravitational Waves, Sumeet Kulkarni

Electronic Theses and Dissertations

The detection of over 90 compact object mergers involving black holes and neutron stars as gravitational wave events by the Advanced LIGO and Advanced Virgo detectors over the course of three observing runs has ushered in the new era of gravitational wave astrophysics. Within a decade, we have transitioned from a detection to the population era, with a combined catalog of these events making it possible to study the population properties of compact objects, estimate their local merger rate, and provide clues as to how they can form binaries. This dissertation focuses on two particular displays of the dynamical dance …

Montesquieu: The Nature Of L’Esprit Des Lois, Christian Jax Murray

Electronic Theses and Dissertations

When Baron de Montesquieu received a copy of his L’Esprit des lois, he was horrified by the total removal and reorganization of critical parts of his text, changed ideas, and an abnormal amount of printing errors in his work. While he saw these issues hindering the reception of his work, this thesis argues that the chaos of the text, in both its style and publication, made the book more popular instead of hindering it. Montesquieu, his editor, and his publisher constructed a new kind of text that was broad in its subject matter and ambiguous in its meaning where its …

The Impact Of Team Success And Team Dynamics On Employee Effort, Tina S. Owens

Electronic Theses and Dissertations

I experimentally examine how team success affects individual employees’ attribution of their own poor performance and whether inter-team dynamics impact their subsequent efforts. I argue, using attribution theory, that more successful, relative to less successful, team performance will lead employees to take more responsibility for their own poor performance and, thus, make more positive effort adjustments. This is because employees are more likely to accept responsibility for their poor performance when they learn that their team as a whole performed well. Additionally, using social identity theory, I argue that employees on teams with stronger team dynamics will make more positive …

Moderation In Online Incel Forums: A Comparison Of Warning Behaviors, Katherine Elizabeth Norris

Electronic Theses and Dissertations

Incels constitute an online community characterized by shared negative perspectives concerning masculinity, women, and societal norms. Platforms such as Twitter and Reddit have implemented content moderation measures aimed at curtailing the dissemination of incels' ideologies, which often promote violence and suicidal ideation. To observe the influence of content moderation on incel discourse, this study examined posts from two distinct incel forums: one subject to moderation and another without such restrictions. Employing thematic analysis, common themes within the posts were identified, and the occurrence of negative language was quantitatively assessed.

From Likes To Looks: The Relationship Between Tiktok Use And Body Satisfaction In A Young Adult Population, Madeline Pruett

Electronic Theses and Dissertations

Body dissatisfaction is becoming an increasingly pervasive problem among young adults, presenting severe implications including the onset of eating disorders and related behaviors. This alarming trend can be attributed, at least in part, to the ubiquity and influence of social media platforms, which serve as a modern catalyst for appearance pressures. While there is a substantial body of research establishing the connection between body dissatisfaction and traditional social media, the examination of newer platforms like TikTok, which have become highly popular among young adults, remains limited. As such, the present study aimed to bridge this gap by investigating the relationship …

Utilizing Embedded Mathematics Instructional Coaching When Implementing High-Quality Instructional Materials, Shannon E. Priest

Electronic Theses and Dissertations

Professional development is essential for teachers to grow in their profession. However, often professional development is a one size fits all approach, and it occurs outside of the teachers’ classroom. This causes teachers to not fully implement new strategies when they return to their classroom. One way to overcome this is to utilize instructional coaching. As our school district began implementing new high-quality instructional materials without guidance, I took on the role of serving as an embedded mathematics instructional coach.

For this qualitative self-study, I acted as an embedded mathematics instructional coach and provided research-based teaching activities to peer teachers …

'Mark My Words' : Measuring Personality Of Global Leaders, Mahesh Acharya

Electronic Theses and Dissertations

With the analysis of thousands of speeches delivered at the United Nations General Assembly to detect personality of global leaders, this dissertation adds a stepping stone to the first image research, in particular, the psychological approaches in International Relations and its stream of Foreign Policy Analysis. Theoretically, it advances the trait models of psychological approaches by building on the lexical theory of personality psychology to analyze the traits of global elites. The theory has been tested over decades showing that linguistic cues like utterances not only provide us with the information on semantics but also the speaker including her personality …

Molecular Modeling Of Inhibitors Of Severe Acute Respiratory Syndrome Coronavirus 2 And Urinary Tract Infections, Priyanka Samanta

Electronic Theses and Dissertations

Infectious diseases are the leading cause of disability-adjusted life years worldwide. Glycans initiate host–pathogen interactions in two particular infectious diseases, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and urinary tract infections (UTIs). In this work, recent advances of computational tools in drug design are utilized to target these glycanspecific host–pathogen interactions for the potential prevention of SARS-CoV-2 or UTIs.
