This approach schedules and assigns tasks using data from maintenance …

Using Participatory Action Research To Make Diabetes Education Accessible For People With Visual Impairment, Ann Sawyer Williams

Dissertations

The three million people who have both visual impairment and diabetes (PVID) represent a large underserved population in the United States. Diabetes self-management education (DSME) is essential for effective management of diabetes. Numerous guidelines exist for making DSME fully accessible to PVID. No national diabetes organization produces basic DSME materials in accessible format, and few DSME programs are fully accessible to PVID. This dissertation used a Participatory Action Research (PAR) approach to discover ways to increase the accessibility of the DSME materials and programs of the Diabetes Association of Greater Cleveland (DAGC) for PVID, adding access for PVID to an …

The Meaning Of A Family History Of Colorectal Cancer In Black Families In The United States, Cassandra Loggins

Dissertations

The purpose of this study is to understand the meaning of a family history of colorectal cancer (CRC) for first-degree relatives of Blacks diagnosed with CRC. Even though CRC is more preventable than other cancers because of effective screening tests for prevention and early detection, Blacks experience a disproportionate burden of CRC compared to other groups. Interventions to increase CRC screening among Blacks have not produced a significant reduction in CRC disparity. Underutilization of CRC screening and low perceived risk of CRC are major factors contributing to CRC disparity. The informing methodological approach employed in this study was hermeneutic phenomenology, …

Puf Proteins: Regulation Of Condition-Specific Mrna Decay And Contributions To Ribosome Biogenesis In Yeast, Anthony Fischer

Dissertations

Regulation of protein expression is critical to organism survival. Multiple disease states arise from aberrant accumulation/aggregation of proteins or reduced production of key enzymes. Cells have many ways to manipulate protein levels, including transcription factors, chromatin modification, modification of messenger RNA (mRNA), and manipulation of proteolytic protein decay. Cells can indirectly control protein volume by controlling mRNA lifespan, which is directly correlated with protein output. Often, sequence-specific elements in mRNA contribute to this lifespan. The Puf family of RNA-binding proteins is ubiquitous throughout eukarya, and plays important cellular and developmental roles through mRNA lifespan regulation. Puf proteins contain a C-terminal …

Application Of Glycosyl Imidates And Nitrates In Carbohydrate Synthesis, Tinghua Wang

Dissertations

Carbohydrates are the most abundant molecules among the four essential classes of biomolecules that also include nucleic acids, lipids and proteins. Unlike proteins and nucleic acids, which follow template-driven synthetic pathways, there is no general route to the synthesis of carbohydrates. The stereoselectivity of the formation of O-glycosidic linkages and the regioselectivity of protection and deprotection of specific hydroxyl groups over others represent two of the major challenges in carbohydrate chemistry. This thesis is dedicated to the development of novel strategies for efficient synthesis of carbohydrate building blocks and stereocontrolled glycosylations for step-economy oligosaccharide synthesis. Novel glycosyl donors with difluoro-3H-indol-2-yl …

Motivation Predicts Self-Control Of Racial Bias After Viewing Alcohol Advertisements, Zachary Wolfgang Petzel

Dissertations

Exerting self-control shifts motivation toward rewarding cues (i.e., approach motivation) and impairs control of racial bias. However, whether approach motivation predicts deficits in control of racial bias is unknown. Exertion of self-control is also related to alcohol use, but whether exerting self-control shifts motivation toward alcohol-related cues is not established. Similar to exerting self-control, viewing alcohol-related cues shifts motivation and promotes racial bias. The current study examined the interaction between exerting self-control and viewing alcohol-related cues on approach motivation and its influence on racial bias. Participants (N = 71) exerted (or did not exert) self-control and then viewed neutral …

Teacher Perceptions Of Ability In Implementing A Culturally Responsive Educational Practice For Culturally Linguistically Diverse Students With Dis/Abilities, Melanie Ziebatree

Dissertations

All children in the United States have the right to an equitable education, regardless of gender, religion, class, race, culture, language, or dis/ability. The literature demonstrates that financial, educational, and legal outcomes are disproportionately negative for those students falling outside of white able-bodied norms and that educational institutions often perpetuate exclusive policies and practices that disproportionately impact culturally linguistically diverse students with dis/abilities. A critical examination of the sociopolitical and contextual factors that fortify the barriers faced by marginalized groups highlights the need for a culturally responsive approach to educating students with multidimensional identities.

To serve the needs resulting from …

Resilience And College Persistence: Characterizing Students Who Have Failed Courses, Mary Merrifield

Dissertations

Students who fail a course early in their college careers are at risk of leaving college before completion of their programs. Little is known about this high-risk group and why some members of this group complete their programs while others do not. This research addressed this gap in the college-level persistence literature by focusing first on differences between completers and non-completers, then on differences between students who fail a course early in their college careers but become completers or non-completers. The goal was to understand the protective value of individual traits beyond the prediction of risk based on membership to …

Divisibility In The Stone-Cech Compactification Of N, Salahddeen Khalifa

Dissertations

Let S a discrete semigroup. The associative operation on S extends naturally to an associative operation on βS,the Stone Cech compactification of S. This involves both topology and algebra and leads us to think how to extend properties and operations that are defined on S to βS. A good application of this is the extension of relations and divisibility operations that are defined on the discrete semigroup of natural numbers (N,.) with multiplication as operation to relations and divisibility operations that are defined on (βN,?) where (?) is the extension of the operation (.). In this research I studied extending …

An Analysis Of African-American Faculty Experiences During The Tenure Process, Katrina M. Hubbard

Dissertations

Abstract

How faculty allocate their time among research, teaching, and service, and the perceived quality of that work determines whether faculty obtain tenure or are released from the university (Bellas & Toutkoushian, 1999; Link, Swann, & Bozeman, 2008; Price & Cotten, 2006). Prior research indicated that African-American faculty comprised 4.5% of the faculty at high-activity research institutions and 3.5% of faculty at very-high-activity research institutions (The Chronicle of Higher Education Almanac 2016-2017, 2016).

The purpose of this study was to 1) document African-American faculty experiences during their tenure probationary period at PWI research institutions; 2) compare faculty experiences during the …

The Dreaded Performance Appraisal: Can The Process Ever Be Comfortable?, Lauren Labat

Dissertations

Previous research has indicated that individuals dislike and resist the performance appraisal process. Fewer studies have examined reasoning for unintentional rating distortion that may result from a lack of training and clear understanding of how to effectively evaluate behaviors. Researchers have shown that the appraisal process is uncomfortable for raters, but empirical studies have yet to explore how to reduce this discomfort. Rater training research has revealed that trained raters have improved observational skills, a more precise vocabulary to describe behaviors, and improved rating accuracy. This research explored the relationship between performance appraisal discomfort and trait motivational factors (i.e., personality …

Understanding Micro-Spatial Crime Patterns: A Comprehensive Trajectory Analysis Of Violent Crime At Street Segments In St. Louis, Mo, Aaron Levin

Dissertations

Spatial crime studies have existed for over a century, but the last 20 years have seen a turn in focus toward micro-spatial units such as street blocks and street segments. A particular subfield of this modern micro-spatial perspective is called crime trajectory analysis, which can isolate patterns of crime at small spatial units over time. Though several crime trajectory analyses have been conducted for coastal cities, the technique has never been applied to Midwestern data. This project fills that research gap by using the group-based trajectory modeling (GBTM) algorithm to uncover patterns of violent crime at street segments in St. …
