Economic Significance In Corporate Finance, Todd Mitton

Faculty Publications

Reporting the economic significance of findings in corporate finance has become increasingly common, but a review of the literature reveals shortcomings in typical reporting practices. Researchers can more effectively communicate the practical importance of findings by using standard measures of economic significance that are scaled by the standard deviation of the dependent variable, by providing all statistics necessary to calculate economic significance, and by providing benchmarks by which to evaluate the magnitude of economic significance. To support these objectives, I show why measures scaled by the standard deviation are preferable, and I provide benchmarks based on hundreds of established findings …

Mechanical and Materials Engineering Faculty Publications and Presentations

This study presents the findings of a wind tunnel experiment investigating the behaviour of micrometric inertial particles with Stokes numbers around unity in the turbulent wake of a stationary porous disk. Various concentrations Φv ∈ ([6 − 19] × 10−6) of poly-disperse water droplets (average diameter 40–50μm) are compared with sub-inertial tracer particles. Hot-wire anemometry, phase Doppler interferometry and particle image velocimetry were implemented in the near- and far-wake regions to study the complex dynamics of such particles. Quadrant analysis is used to explore the shear effects of the particle wake interaction. Turbulence statistics and particle size distributions reveal distinct …

The Ejection Of Large Non-Oscillating Droplets From A Hydrophobic Wedge In Microgravity, Logan Torres, Mark M. Weislogel

Mechanical and Materials Engineering Faculty Publications and Presentations

When confined within containers or conduits, drops and bubbles migrate to regions of minimum energy by the combined effects of surface tension, surface wetting, system geometry, and initial conditions. Such capillary phenomena are exploited for passive phase separation operations in micro-fluidic devices on earth and macro-fluidic devices aboard spacecraft. Our study focuses on the migration and ejection of large inertial-capillary drops confined between tilted planar hydrophobic substrates (a.k.a., wedges). In our experiments, the brief nearly weightless environment of a 2.1 s drop tower allows for the study of such capillary dominated behavior for up to 10 mL water drops with …

Kristen Du Mez Tells Me How Evangelicals Fell In Love With John Wayne, Kristin Du Mez

University Faculty Publications and Creative Works

When the Access Hollywood “locker room talk” tape hit the mainstream on October 7, 2016, both Russell Moore and historian Kristin Du Mez were horrified. But while Moore felt surprised by the evangelical response—or lack of response—to the video, Du Mez saw it as a predictable outcome of militant masculinity within evangelicalism. In their conversation, and in her book Jesus and John Wayne, Du Mez explains why. On this episode of The Russell Moore Show, Moore and Du Mez talk about the overlap of history, politics, and Christianity when it comes to understanding American evangelicalism’s relationship to gender. They also …

An Investigation Of Principals’ Social Justice Leadership And Black Male Academic Achievement, Brain L. Gibson

All Dissertations

Black males in K-12 school systems across the nation continue to face formidable challenges such as low graduation rates, overrepresentation in special education, high out-of-school suspension rates, and underperformance in the classroom (Bryan, 2020; Grace & Nelson, 2019; Johnson & Bryan, 2017; Powell, 2018). Despite decades of research devoted to addressing the educational and social injustices Black males face, many scholars contend that such attention has resulted in minimal change, and a revised narrative for managing the state of Black males is needed (Adedoyin et al., 2019; Carter, 2019; Johnson & Bryan, 2017).

Some scholars have insisted that the academic …

A Case Study Examining Students' Experience In Student-Centered Learning Practices Implemented At An Air Force Training Course, Mindy Fisher

Doctoral Dissertations and Projects

The purpose of this case study is to examine students’ experience of student-centered learning practices implemented at an Air Force training course. At this stage in the research, student-centered learning is generally defined as a learning approach during which students generate learning opportunities and reconstruct knowledge dynamically in an open-ended learning environment (Lee & Hannafin, 2014). The theory guiding this study is constructivism based on Lev Vygotsky’s learning theory which represents an epistemological perspective as to the nature and evolution of individual understanding where learners create their own learning. Student-centered learning environments are rooted in constructivist approaches (Creswell & Poth, …

Developing An Intentional Disciple Making Strategy For Fathers To Lead Their Families In Spiritual Transformation, Michael Cauthorne

Doctoral Dissertations and Projects

Do current student ministries produce disciples that can stand the test of the current culture? Has creating a separate ministry worked against God’s plan for making disciples? Statistics from across the Church would suggest the American Church is in decline. Within the Southern Baptist Convention there has been a continual decline in baptisms over the past few years. This project will seek to determine if there is a correlation between how student ministries are led in the modern church to how effectively the church has been in making disciples. With research and data collected from current and former student ministries, …

Intervention: Helping The Rural Baptist Church Identify Areas Of Strength And Weakness For Greater Kingdom Service, Anthony Jerome Baylor

Doctoral Dissertations and Projects

The rural Baptist Church has historically been a place of tradition, cultural importance, and refuge. It has been led by a wealth of great leaders who have served generations of faithful members. Over time, many rural Baptist Churches have seen a gradual decline, and some are on the verge of extinction. This decline may be a direct result of those churches attempting to continue unnecessary traditions and unproductive ministries. These churches also sacrifice future interests and prospects for institutional practices that do not fulfill the Great Commission and promote destructive practices. To initiate an intervention into the destructive practices of …

Commercial Violin: Creating A Hybrid Twenty-First Century Collegiate Violin Curriculum, Ryan Joseph Ogrodny

Doctoral Dissertations and Projects
