How Does The Market View Share Repurchases: Five Possible Book Values In The Fama-French 3 Factor Model, Jaime Peters

Dissertations

Share repurchase activity has grown significantly over the past twenty years and has emerged as the most popular technique for returning cash to shareholders. Current U.S. generally accepted accounting principles treat share repurchases as a return of capital to shareholders, recording the repurchased shares at market prices and offsetting them against contributed capital accounts. This treatment reduces the recorded book value of the equity of companies. Of course, companies can reissue these shares to fulfill stock option contracts, as consideration in acquisitions, and/or in secondary offerings. These economically relevant uses of repurchased shares suggest that the market may treat share …

Corporal Punishment In Eastern Nigeria, Gerald N. Nwafor

Dissertations

In Nigeria, corporal punishment is used widely in Nigeria’s judicial system, the home, and the classroom. The prevalent opinion in the education community is that corporal punishment helps students learn better and faster, keeps order in the classroom, and promotes a high student performance level. Reliance on corporal punishment is embedded in the religious, cultural, social, and moral beliefs and understanding of life. Corporal punishment takes many forms, but the most common in the school system is caning or flogging, which is the forceful and severe striking of the student’s body, using a stick of wood, usually on the back, …

An Inferentially Robust Look At Two Competing Explanations For The Surge In Unauthorized Migration From Central America, Nick Santos

Dissertations

The last 8 years have seen a dramatic increase in the flow of Central American apprehensions by the U.S. Border Patrol. Explanations for this surge in apprehensions have been split between two leading hypotheses. Most academic scholars, immigrant advocates, progressive media outlets, and human rights organizations identify poverty and violence (the Poverty and Violence Hypothesis) in Central America as the primary triggers responsible. In contrast, while most government officials, conservative think tanks, and the agencies that work in the immigration and border enforcement realm admit poverty and violence may underlie some decisions to migrate, they instead blame lax U.S. immigration …

Leadership Development In Saudi Arabia’S Private Sector: A Mixed Methods Approach, Khaled Hanaky

Dissertations

There is currently a proliferation of business-focused leadership development programs in Saudi Arabia. These programs represent a reaction to the shortage of qualified leaders who can drive and sustain both recent and future advances introduced by Saudi Vision 2030, the national transformation program that is introducing social and economic reforms. Importantly, business leadership development has not been studied in this context of contemporary Saudi Arabia.

This study examined the state of Saudi leadership development programs by employing an explanatory sequential case study design that focused on a particular leadership development program. Through the use of surveys and participant interviews, results …

Does Winning Matter? An Examination Of The Impact Of Success On Former Student-Athlete Philanthropic Giving, Zach Harris

Dissertations

Intercollegiate athletic departments (ICAs) rely on philanthropic giving to remain relevant in the “arms race” that is college athletics. Donations provide the necessary resources (scholarships, upgraded facilities, etc.) to compete with rival programs for prospective student-athletes and fans. Previous research in ICA philanthropy has found that team success is one of the key factors driving donations to athletic programs. However, much of the research in this field has centered on athletic giving on a macro-level, focusing on the overall alumni population of an institution. While this research is important for colleges and universities, it misses on measuring the impact that …

Impact Of Diabetes Self-Management Education On Adults With Diabetes And Mental Illness, Brooke Tullis

Dissertations

Approximately 9.4% of the population of the United States, or 30.3 million Americans, has diabetes mellitus. Diabetes is the seventh leading cause of death and places a significant financial strain on the healthcare system with approximately $327 billion in estimated expenditures. In Ohio, 13.5% of the population has diabetes, which represents a 4.1% increase above the national average. Additionally, individuals with mental illness are at an increased risk for diabetes due to lower self-efficacy and limited performance of self-care activities compared to the general population. This results in poor glycemic control and leads to an increased risk for diabetes complications. …

The Power Of Sulfur: A Study Of An Isothiocyanate Chiral Derivatizing Agent, Thioamide Based Chiral Solvating Agents, And The Geometry Of Sulfonamides, Emily B. Crull

Dissertations

This three-part dissertation is connected by the thread of utilizing sulfur-based functional groups, hence the power of sulfur. The first project was the development of a pentafluorobenzene based isothiocyanate chiral derivatizing agent (CDA), a class of compounds that differentiate enantiomers through covalent bond formation. This project, which was addressed using a combination of synthetic and computational methods and NMR analysis, gave rise to an CDA that was highly selective for amines and computationally predictable. Branching off of that, the second project demonstrated the use of two thioamide chiral solvating agents (CSAs), which had never been reported as a core functional …

On The Treatment Of Bilinear Forms Involving Matrix Functions As Perturbations Of Quadratic Forms, Keelia Altheimer

Dissertations

Optimizing the approximation of bilinear forms using a one-sided perturbation, where the computation of the approximate solution is generated faster while using less storage or reusing information is possible. Standard methods for approximation like Lanczos and others exist; however, separating the work a little bit and having the bilinear form relate to the quadratic form can yield a more efficient algorithm. When we have an application where the needs are different, it is helpful to understand how the processes like symmetric Lanczos and unsymmetric Lanczos relate to one another so that we can find a way to break things down …

Data-Driven Approaches To Complex Materials: Applications To Amorphous Solids, Dil Kumar Limbu

Dissertations

While conventional approaches to materials modeling made significant contributions and advanced our understanding of materials properties in the past decades, these approaches often cannot be applied to disordered materials (e.g., glasses) for which accurate total-energy functionals or forces are either not available or it is infeasible to employ due to computational complexities associated with modeling disordered solids in the absence of translational symmetry. In this dissertation, a number of information-driven probabilistic methods were developed for the structural determination of a range of materials including disordered solids to transition metal clusters. The ground-state structures of transition-metal clusters of iron, nickel, and …

Semantic Classification Of Multidialectal Arabic Social Media, Tom Rishel

Dissertations

Arabic is one of the most widely used languages in the world, but due in part to its morphological and syntactic richness, resources for automated processing of Arabic are relatively rare. Arabic takes three primary forms: Classical Arabic as seen in the Qur’an and other classical texts; Modern Standard Arabic (MSA) as seen in newspapers, formal documents, and other written text intended for widespread distribution; and dialectal Arabic as used in common speech and informal communication. Social media posts are often written in informal language and may include non-standard spellings, abbreviations, emoticons, hashtags, and emojis. Dialectal Arabic is commonly used …

Structural Origin Of Thermal, Mechanical Properties And Morphological Behaviors Of Semiconducting Polymers, Song Zhang

Dissertations

The past decades have witnessed a surging exploration of semiconducting polymers for the application of wearable and flexible organic electronic devices. Despite the increased amounts of molecular engineered polymers and their much-improved electrical performances, a systematic study of the structure-thermal/mechanical property-morphology relationship of semiconducting polymers is still less investigated.

To understand the thin-film mechanical properties, a pseudo-free standing tensile tester was self-built and utilized to obtain their real-time stress-strain behaviors through uniaxial stretching on top of the water surface. It also enables the first quantitative measurement of fracture energy on ultrathin polymeric films. Through multiple mechanical testing methods (i.e., strain-rate …

The Relationship Between School Principals’ Servant Leadership Attributes And Teacher Morale, George Larry Johnson

Dissertations

Teacher morale in schools has a profound impact on the school and the level of student achievement. Low teacher morale cases high teacher turnover and causes teachers to be resistant to change, while schools with high teacher morale boast better teacher attendance, higher student achievement, and a sense of cohesiveness in the school. A principal’s leadership style has a significant effect on the level of teacher morale in schools. Servant leadership is a theory of leadership, first developed by Robert Greenleaf, where the leader leads by serving and puts followers first. Servant leadership theory has proven to be an effective …

Comparison Of Manipulatives Effect On Academic Achievement In Preschool Math, Ashley Stewart

Dissertations

Students in the United States tend to possess poor academic performance in mathematics compared to other developed countries. Despite the increased preschool enrollment and attendance, there are academic disparities among preschool students. Earlier exposure to mathematical concepts can positively affect student outcomes. Research supports the idea that early exposure and mastery of patterning skills and non-symbolic quantity knowledge are trajectories of math academic achievement during elementary and middle-level grades (Rittle-Johnson, Fyfe, Hofer, & Farran, 2016). Students who begin with mathematics deficiencies, without proper intervention, tend to continue to lack understanding of foundational math skills that are essential for proficiency in …

Applied Microeconomics And Business Intelligence In The Digital Age, Thomas J. Weinandy

Dissertations

The Digital Age is defined by advances in big data, low-cost computing, and modern analytical methods. In three chapters, I apply microeconomic thought to the influence these digital technologies have on business and consumer decision-making.

Chapter One considers how Transportation Network Companies (TNCs) like Uber and Lyft impact the relationship between the quantity of car service trips and fuel prices. I find that a single day 1% increase in fuel prices is associated with a 0.367 to 0.486% decrease in the number of TNC trips and a 0.033 to 0.088% increase in the number of taxi trips, even though the …

The Neuroanatomical, Neurochemical, And Phenomenological Correlates Of Social Bonding, Empathy, And Flow In Music Improvisation, Edward A. Roth

Dissertations

The three studies in this dissertation explore the biological and phenomenological under-pinnings of music improvisation related to bonding, empathy, and flow. Musical improvisation is a multi-dimensional behavior encompassing motor, cognitive, affective, and often social domains, and as such, it is reasonable to consider that music improvisation shares many characteristics with other forms of non-musical extemporaneous behavior, such as carrying on a verbal dialogue. The primary aims of this three-study dissertation were to (1) determine the feasibility of the study designs and interdisciplinary methods; (2) examine potential differences in the neuroanatomical and neurophysiological correlates of improvisation between non-musicians and musicians; and …

This study evaluates the practicalities and consequences of designating one month (March) out of the calendar year for the commemoration of women’s history. In the 1970s and 1980s, national women’s organizations such as the Women’s Action Alliance (WAA) collaborated with the Smithsonian Institute and the Women’s History Program at Sarah Lawrence College to build programs to increase awareness of women’s history. Using an interdisciplinary approach grounded in feminist theory, media studies, and historical memory studies, this project contextualizes the commemoration through its connection to 1970s women’s activism, explores its usefulness as a tool for building educational equity, and questions its …

On Problems In Random Structures, Ryan Cushman

Dissertations

This work addresses two problems in optimizing substructures within larger random structures. In the first, we study the triangle-packing number v(G), which is the maximum size of a set of edge-disjoint triangles in a graph. In particular we study this parameter for the random graph G(n,m). We analyze a random process called the online triangle packing process in order to bound v(G). The lower bound on v(G(n,m)) that this produces allows for the verification of a conjecture of Tuza for G( …

The objectives in this dissertation study were to explore (a) how online parent training in the modified Teach-Model-Coach-Review Instructional approach can be implemented to improve the parents’ …

“Will You Scream With Me?”; The Experience Of Expressive Therapy For One Adult Survivor Of Childhood Sexual Abuse And Their Counselor: A Single-Case Study Giving Voice To Complex Trauma, Maegen Grace Horton

Dissertations

Due to the high prevalence of childhood sexual abuse (Finkelhor, 1994), most mental health counselors will likely provide treatment to adult survivors. However, many counselors lack specialty training in working with this vulnerable population (Priest & Nishiinura, 1995). Recent neurobiology research has illuminated the long-lasting effects of childhood sexual abuse on the brain and its implications for emotional expression and regulation (van der Kolk, 2014). Informed by this research, it stands to reason that expressive therapy, defined by Malchiodi (2005) as “the use of art, music, dance/movement, drama, poetry/creative writing, play, and sandtray within the context of psychotherapy, counseling, rehabilitation, …

Student And Teacher Relationships At Secondary Level, Christine Fisher

Dissertations

Interpersonal relationships between teachers and students built within a learning context have a significant influence on the development of learners’ social and emotional life. Higher levels of engagement, attachment, and motivation are common among students who strongly connect with their teachers. This study aimed to obtain a deeper understanding of care related to student-teacher connection from students’ experience. Noddings Theory of Care believes that caring associations are ontologically essential; thus, they play a great part in the development of student’s learning process. However, care can fail to realize the expected outcomes according to Noddings’ theory if it is misinterpreted as …
