Yet few studies about mathematics teachers’ knowledge for teaching have been conducted in the Saudi context. This study investigates Saudi elementary mathematics teachers’ knowledge for teaching in the content strand of rational numbers with an emphasis on fractions, which is an important step …

Contextual Factors Influencing The Acute Care Registered Nurse's Response To Clinical Alarms, Kathleen M. Stacy

Dissertations

Nurses are faced with a multitude of clinical alarms on a daily basis. There is an inherent expectation that upon hearing an alarm the nurse will immediately respond to assess the situation and initiate appropriate action to correct the problem. Yet this does not always occur. Issues with alarm responsiveness can pose a serious threat to patient safety. The purpose of this qualitative study was to develop a broader understanding of the contextual factors that influenced the acute care nurse's response to clinical alarms. This study used an interpretive phenomenological methodology to study the lived experiences of the nurses who …

Editing The Double Bass Concerto Of Antonio Scontrino, Roberto Pineda

Dissertations

Antonio Scontrino (1850-1922) was an important Italian Romantic composer, virtuoso double bassist, and respected pedagogue who is relatively unknown outside of the Italian musical community. His compositional output is prolific and includes string quartets, operas, symphonies, concerti, solo pieces, songs, and religious works. Indeed, Scontrino was a compelling composer who deserves more attention from the international musical community. In addition to his compositional expertise, he was an artful double bass performer whose works for the instrument, while distinctly idiomatic, are compositions of high quality.

This dissertation provides a description of the composer’s life and the events that transpired around Scontrino …

Traits Of Character That Facilitate Formation Of Exemplary Nurses In Bachelor Of Science Nursing Programs, Jean Marks

Dissertations

Constructivist grounded theory methods were applied in this study to explore traits of character that facilitate the formation of exemplary nurses in Bachelor of Science Nursing (BSN) programs. Interest in this study was prompted by a desire to examine attributes beyond academics alone that contribute to the formation of excellent nurses. The intent was to promote clarity in describing these attributes for further scholarly discussion.

Framing this study was Aristotle’s doctrine of the golden mean (Aristotle, 350 B.C.E./1934). Operational definitions consistent with this doctrine were created for the concepts of character, character traits, and exemplary nursing practice. The concept …

Childbirth And Control Behind Bars: A Descriptive Qualitative Analysis Of The Maternal Perception Of Control In Women Who Have Given Birth While Incarcerated, Lorin Raines

Dissertations

The perception of control during childbirth has been widely studied in various setting and groups. Many factors have been found to aid or impede the perception of control for birthing women. Significance of that perception of control during childbirth has also been measured in past studies. This descriptive qualitative study advances the knowledge of the perception of control during childbirth and examines a population that has thus far been excluded. Four previously incarcerated women participated in semi-structured interviews about their experience of giving birth while incarcerated and their perception of control during that time. The women were from diverse backgrounds …

Hemodynamic Response During Sedentary Behavior In Black/African American And White Males, Raymond Jones

Dissertations

Emerging evidence suggests that uninterrupted sitting has a deleterious impact on hemodynamics, namely a reduction in blood-flow induced shear stress in peripheral vessels, which leads to vascular dysfunction and increased arterial stiffness. Few studies have examined the cerebrovascular response, and no studies have discerned potential racial differences on the hemodynamic response to uninterrupted sitting. Purpose: To examine racial differences in the hemodynamic response during an acute period (1-hour) of uninterrupted sitting between Black/African American and White males. Methods: Twenty-four adult males (50% Black/African American) between the ages of 18 and 35 years and relatively healthy (i.e., free of …

Transformers: The Relationship Between Instructor And Course Persistence Among Community College Students, Jairus L. Johnson

Dissertations

U.S. community colleges play a unique role in providing higher education opportunities for members of society and are often viewed as the gateway to a post-secondary education (Savi, 2011). Two-year colleges foster a robust mission that is supported by a variety of curricular functions that tailor to a diverse student population. Furthermore, through an open-door policy, admittance only requires a high school diploma or equivalent. The aforementioned factors have created inherent challenges associated with student persistence, institutional retention, program completion, and graduation rates among community colleges. As compared to universities, community colleges have lower graduation and retention rates.

Researchers suggest …

An Examination Of The Influence Of Multi-Scale Processes And Connectivity On The Population And Assemblage Dynamics Of Headwater Fishes, Josh P. Hubbell

Dissertations

Typified by their branching pattern, headwaters are numerically abundant as the density of these habitats increases with increasing distance from the base of a dendritic river system. Connectivity among headwaters is complex, resulting in the spatial isolation of populations. Headwater specialists have evolved a suite of traits that permit these species to permanently reside within these habitats. The spatial configuration and connectivity of headwaters has repercussions for metapopulations and meta-assemblages. I investigated how multi-scale processes and connectivity influenced the patch occupancy, coexistence, movement ecology, population structure, and gene flow of headwater specialists. In chapter two, I used occupancy modeling to …

Living On Campus Is Beneficial: Studying The Impact Of Student Involvement Through Living-Learning Communities, Stephen R. Mccay

Dissertations

Since the early days of higher education, living-learning communities have been beneficial for student success, involvement, and retention. A living-learning community can be studied using the following as a basic definition for this research: a group of students living together who have a purpose of focusing on learning outside the classroom and that interacts with the institution’s staff, who assist with the students’ holistic development. Research suggests that students who are involved and those who live on campus have greater academic success and are more likely to return for their next academic semester. Astin’s involvement theory explores the interactions between …

A Signal Detection Framework For Evaluating The Effects Of Feedback On Stroke Recognition, Jordan D. Bailey

Dissertations

The impact of stroke on the lives of individuals and the healthcare system is considerable. Damage from stroke can be reduced if the treatment is administered at the appropriate time so early recognition is essential. One problem is that strokes present in a variety of ways that sometimes do not fit into the Facial drooping, Arm weakness, Speech difficulties and Time (FAST; American Heart Association, 2019) acronym. Signal detection is one way to measure decision making under conditions of uncertainty (e.g., discriminating stroke symptoms and risk factors from other symptoms, and non-risk factors). The methodology also allows us to consider …

Objectively Determining The Language-Related Communication Challenges For In-Flight Operations, Fehime Utkan

Dissertations

Communication breakdowns between pilots and air traffic controllers (ATCs) have been identified as primary factors in fatal airplane accidents (Wu et. al., 2019; Bauh & Stolzer, 2018; Ritter, 1996; Eurocontrol, 2011). Although there are various aspects that have affected communication efficiency, language-related issues have been mostly associated with transmissions involved in serious incidents, especially in multicultural flight environments (Sexton & Helmrich, 2000). More than 2,000 people have died in accidents where miscommunication was a primary factor (Bauh & Stolzer, 2018; Patty, 2016). By the year of 2025, the air transportation system is projected to become more complex, and the volume …

Exploring The Relationship Between Student Online Discussion-Board Activity And Student Grades, Frank Robert Talbott

Dissertations

As students, instructors, and higher-education administrators delve further into cyberspace, scholarly literature and practice require further insights into the dynamics of online learning. This study examined the relationship between online student discussionboard activity and student grades and, consequently, addressed a dearth in the literature about this relationship. Student Involvement Theory provided the theoretical foundation of this research. This study’s sample consisted of 200 online undergraduate students in online business-analytics courses. Regression-analyses findings supported the relationship between student postings of certain mathematical-symbol references (e.g., for equalities, inequalities, addition, subtraction, multiplication, and division) and student grades. Therefore, administrators, faculty, and course designers …

Postural stability was assessed using traditional center of pressure …

Performance Guide And Recording Of Three Twenty-First-Century Compositions For Solo Cello, Katarina Majcen Pliego

Dissertations

The twenty-first century boasts a vast repertoire of solo cello pieces. While many editions might feature phrase markings and other performance indications by the composer, they rarely include bowing indications, fingerings, and other practical advice. Due to the diversity and sometimes technical difficulty of the twenty-first-century solo cello repertoire, most new works now include guidelines or performance guides written by the composer or first performer. I have selected three pieces according to the following criteria: no performance guide is currently available; the published score lacks editorial guidance on performance issues such as bowing and fingering; and no commercially available recording …

Incorporating Critical Thinking: Self-Perception Of Teachers’ Ability To Promote Critical Thinking Skills In Primary Grades (K-2), Courtney Milligan

Dissertations

The ability to think critically is a fundamental life skill and is an essential part of being a productive and contributing member of society. “Research shows that elements of critical thinking need to be taught explicitly” (Haber, 2020). The practice of developing critical thinking skills while students are initially "developing as thinkers" in primary grades is essential. According to Wagner (2008), his research finds that children should begin developing critical thinking skills as soon as they “are capable of abstract thinking” (p.17). Wagner (2008) argues that students need to develop these essential skills to effectively participate in our democracy and …

Cost-Effective Gnss Hardware For High-Accuracy Surveys And Its Prospects For Post-Processed Kinematic (Ppk) And Precise Point Positioning (Ppp) Strategies, Johnson Olusegun Oguntuase

Dissertations

This dissertation determines for the first time the vertical accuracy achievable with low-cost mass-market multi-frequency, multi-GNSS (LM3GNSS) receivers, and antennas in the context of Ellipsoid Reference Survey (ERS), usually employed in bathymetric operations aboard survey platforms. LM3GNSS receivers are relatively new in the market, and their emergence is driven by the automobile industry and several mass-market applications requiring location-based solutions at high accuracies. It is foreseeable that emerging hydrographic survey platforms such as autonomous surface vehicles, small unmanned aircraft, crowd-sourced bathymetric platforms, and offshore GNSS buoy will find LM3GNSS receivers attractive since they are power- and cost-effective (often less than …

Narrowing Attainment And Achievement Gaps Of African American Third Grade Students Through Culturally Responsive Teaching, Phyteria Proctor, Phyteria Lashawn Proctor

Dissertations

Literature suggest culturally responsive teaching is one of our most powerful tools for accelerating student learning and helping students find their way out of the gap. Billions of dollars have been invested in creating educational equity, but the data have shown that inequality in achievement still exists. However, school districts are beginning to focus more on being aware of and sensitive to the cultural and social needs of African American students. When school communities accept the challenge of changing the culture within their schools to ensure all students reach their full potential, then the achievement gap can be eradicated.

Monitoring Salt Diapir Related Land Deformation And Distribution: A Geophysical And Remote Sensing Approach Jazan Province, Saudi Arabia, Hannah G. Pankratz

Dissertations

Salt diapirs are rarely preserved on the surface and seldom considered as environmental hazards. The Jazan city diapir (JZD) is located in southwest Saudi Arabia along the Red Sea coastal plain and outcrops in the middle of a rapidly growing port city. The intrusion of the diapir (~ 2 km²) into the overburden sediments continues to cause uneven surfaces, compromises building foundations and infrastructure, caused dissolution sinkholes, and limits the expansion of the city along the coastline. This research aims to better understand the distribution and deformation associated with salt diapirs in arid environments.

Female Graduate Students’ Experiences And Career Orientations In Stem: A Comparative Case Study, Jasvir K. Pannu

Dissertations

Regardless of implementation of government policies to promote STEM education and eradicate the underrepresentation of women and minorities, the number of women choosing STEM throughout their educational career remains low. In 2018 65% doctorate degrees were awarded to men and only 35% to women. Moreover, 40% of all students enrolled in doctorate programs drop out before completion. The process of socialization in graduate school and students’ non academic responsibilities play critical roles in graduate students’ success and future career orientations. Processes of socialization involve interactions with faculty, peers, and administration while taking courses and conducting dissertation research. Non academic engagements …

Atmospheric Turbulence Distortion In Video: Restoration Utilizing Sparse Analysis, Benjamin J. Sanda

Dissertations

The removal of atmospheric turbulence (AT) distortion in long range imaging is one of the most challenging areas of research in imaging processing with an immediate need for solutions in several applications such as in military and transportation systems. AT exacerbates distortion due to non-linear geometric blur and scintillations in long-distance images and videos, severely reducing image quality and information interpretation. AT negatively impacts both human and computer vision systems, compromising visibility essential for accurate object identification and tracking.

In this dissertation, a novel sparse analysis framework is developed to address efficient AT blur and scintillation removal in video. Operating …

An Intensive Longitudinal Functional Lineary Model With Multiple Time Scales, Mostafa Zahed

Dissertations

In this study an intensive longitudinal functional model with multiple time-varying scales with scalar outcome, multiple functional predictors, one or more scalar covariates and subject-specific random intercepts through mixed model equivalence was proposed. The framework consists of estimating a time-varying coefficient function that is modeled as a linear combination of time-invariant functions with time-varying coefficients. The model uses information structure of the penalty, while the estimation procedure exploits the equivalence between penalized least squares estimation and a linear mixed model representation. The process is empirically evaluated with several simulations. The simulation suggested that as the sample size and level of …

An Evaluation Of One School District Standards Assessment Program, Derrick King

Dissertations

This project focuses on how one school district uses quarterly assessments to identify standards students have not mastered. This project identifies how some schools utilize quarterly assessment data with varying results. One problem I have identified is a lack of a consistent expectation from district leadership, regarding the expectation for how schools should use the assessment program. In my research, I examine two schools that use the assessment program differently. The literature I present reveals how the program can help improve student achievement. The research reveals what is working well, and what is not. In closing, I recommend implementing a …

Confluences Of Student Leadership And White Privilege: Exploring Consciousness-Of-Self With White Student Leaders, Jeremy N. Davis

Dissertations

There is a growing body of literature signaling the relevance of race in leadership development, but many conventional models do not prompt exploration of this social identity. The omission of race in leadership curriculum is disadvantageous for all college students, but among White student leaders, it may be a continuance of White privilege. The purpose of this constructivist study was to explore how White student leaders make meaning of their racial identity, and corresponding privilege, through a relevant leadership framework. Racial caucusing was employed as a method to prompt discussion and gather narratives from four White student leaders. Findings from …

A Contemporary Understanding Of The Effects Of The Third Wave Of School Finance Litigation, Jason Richard Kopanke

Dissertations

School finance litigation is often conceptualized as occurring in three waves, with the most recent wave, the third wave, beginning in 1989. Third wave litigation argues for improvements in school funding by claiming that schools are inadequately funded, resulting in students being deprived of their constitutional right to a certain level of education. Despite this third wave’ thirty-one year history, its effects remain understudied. In this secondary data analysis thirty-three cases where plaintiffs prevailed and twenty-nine cases where defendants prevailed were used to examine the effects of third wave school finance litigation on school funding and student achievement, and to …
