Examining The Relationship Between Student Engagement And Stem Persistence At An Hbcu, Saundra Yates Evans

Dissertations

A growing imbalance in the demand for a science and technology workforce and the declining availability of a science and technology talent pool is challenging America’s world dominance in research and innovation, economic performance, and quality of life. Contributing to this imbalance is flatness in the trend of students selecting science, technology, engineering and mathematics (STEM) majors coupled with decreasing rates of retention in STEM disciplines. Many research studies and reports emphasize that incorporating the untapped talents of Americans who are underrepresented in STEM disciplines--African-Americans, Hispanics, and women--is necessary to increase the pipeline of STEM graduates. A synthesis of college …

Curriculum Design And Language Learning: An Analysis Of English Textbooks In Brazil, Ellen Nogueira Rodrigues

Dissertations

Problem

The textbook is the most important resource for English as a Foreign Language (EFL) classrooms in Brazil, defining the course to be followed and the teaching and learning processes for language learning. Therefore, it is necessary to understand through an educational perspective the curriculum design employed in the textbook, and the language learning processes used based on the communicative approach, the current favorable approach to English teaching in Brazil. Textbooks writers typically indicate their alignment to the communicative framework. So the problem that exists is the lack of studies on the approaches and processes used in the construction of …

Design, Synthesis, And Biological Evaluation Of Folate Targeted Photosensitizers For Photodynamic Therapy, Laura Jean Donahue

Dissertations

Photodynamic therapy (PDT) is used to treat cancer, and involves a highly conjugated molecule, called a photosensitizer (PS), which is excited by wavelengths of light from visible to infrared. Photosensitizers that are highly conjugated will absorb longer wavelengths (600 – 900 nm), and have the potential to destroy cells of deeper tissue cancers. In PDT, a PS is administered to the patient, and after an appropriate time delay, the tissue is then exposed to light of a specific wavelength necessary for excitation of the PS. A transfer of energy can take place between the excited PS and oxygen that is …

The Influence Of Media Violence On The Neural Correlates Of Empathic Emotional Response, Laura Stockdale

Dissertations

Decades of research on the effects of media violence have shown that exposure to violence in the media is related to increased aggression, decreased prosocial behavior, and decreased empathy. Video games, which contain some of the most graphic, realistic, justified, and rewarded aggression have been shown to increase aggressive behavior and decrease prosocial behavior. Researchers suggest that emotional face processing and inhibitory control may be important factors associated with aggressive behavior and empathy; however, few researchers have examined these variables in chronic and nonchronic violent video game players. Therefore, the goal of the current study was to understand differences in …

The Gut-Liver Axis Regulates Pulmonary Inflammation After Intoxication And Burn Injury, Michael M. Chen

Dissertations

The increasing prevalence of binge drinking and its high association with traumatic injury warrant further investigation into the mechanisms underlying the worsened clinical outcomes associated with this combined injury. Existing literature suggests the liver is at the center of the postburn systemic response with crosstalk between the intestinal microbiome and the liver playing an important role after injury. There is a paucity in the literature, however, regarding the role of the gut-liver axis in the common clinical scenario of burns preceded by alcohol intoxication. Previous studies in our laboratory demonstrated intoxication potentiates postburn hepatic damage and IL-6 production in a …

Beyond Dialogue: Avenues Toward Christian Unity, Jeffrey Kirch

Dissertations

This project seeks to investigate the status of ecumenism following the Second Vatican Council. There is general agreement that work towards the unity of the Christian Church has come to a standstill. The ecclesiologies of Walter Kasper, Joseph Ratzinger, and Richard McBrien contribute to reinvigorating the ecumenical movement. Specifically, the place of ecumenical dialogue and an "ecumenism of life" show signs of promise. By taking contributions from each of the theologians an effective strategy for moving forward can be developed.

Computational Investigation Of The Influence Of Heating Modes And Moisture Content On Pyrolysis And Ignition Of Live Fuels, Bangalore Lingaraj Yashwanth

Dissertations

The burning of an isolated leaf-like element was computationally investigated in a series of studies, motivated by recent burning experiments performed on live leaves of manzanita (Arctostaphylos glandulosa). In this study, the relative impor- tance of heating modes, effect of fuel moisture content on pyrolysis and combustion of live fuels is explored in stages. A preliminary study was conducted on a simpli- fied one-dimensional configuration, using Gpyro. The heating sources were modeled through convection and/or radiation as boundary conditions. Results showed that the increase in radiative source temperature substantially affects ignition time; how- ever, it has marginal influence on mass …

Photoluminescence Of Cadmium Selenide-Based Quantum Dots In The Presence Of A Metal Oxide, Kira D. Patty

Dissertations

Quantum dots (QDs) are semiconductor nanocrystals that self-assemble from solution and come in a variety of shapes, sizes, and materials. Due to their extremely small sizes, QDs exhibit atom-like quantum mechanical properties that make them highly desirable for many applications and for fundamental research in quantum mechanics. Further, when continuously irradiated, the intensity of QD emissions can increase over time; a phenomenon referred to as photo-induced fluorescence enhancement (PFE). For almost every application that deals with the optics of QDs, the enhancement of their quantum efficiency and control of their photoluminescence properties is highly desirable. This research explores how the …

Self-Perceived Stress Of Undergraduate Students Before And After Participation In A Breathing Meditation Intervention: A Mixed Methods Study, Cindy Oneida Sloan

Dissertations

This mixed methods study examined the effects of an eight-week breathing meditation intervention on the self-perceived stress of undergraduate students. Previous research suggests meditation is an effective strategy to alleviate stress and stress-related symptomatology (Baer, 2003; Conley, Travers, & Bryant, 2013; Shapiro, Brown & Astin, 2011). Forty-one undergraduate student volunteers participated in the study and were randomized into either an intervention group or control group. The intervention group met once per week for eight weeks and participated in a nine minute guided breathing meditation. At the conclusion of eight weeks participants, when compared with the control group, reported significantly lower …

Migratory Loss And Depression Among Adult Immigrants Of Chinese Descent, Christine Chih-Ting Chang

Dissertations

The immigration process does not only include the life after relocating to a new environment and settling down in the host society but also includes separation from the life before their departure and the negotiation between redeeming and closing their losses. This study was the first attempt to investigate migratory loss among adult immigrants of Chinese descent. The study developed the Migratory Loss Scale and examined the moderation effect of acculturation as well as the moderation effect of the presence of immigration-related meaning on the relationship between migratory loss and depression. The study also examined the mediation effect of the …

Allosteric Regulation Of The Ribosome By L-Tryptophan, Emily R. Gordon

Dissertations

Ribosomes often times work in unison with both nascent peptides and accessory molecules to regulate expression of genes by controlling protein synthesis. This allows for fine regulation of gene activity based on current cellular physiology. In prokaryotes, there are numerous differences among regulatory nascent peptides that induce ribosome arrest, thus allowing for specificity in regulation. In the tna operon the amino acid L-tryptophan, L-Trp, can selectively interact with the ribosome translating tnaC mRNA, and thereby control the expression of the enzyme tryptophanase and an L-Trp transporter. It has been suggested that the combined action of L-Trp and the regulatory TnaC …

Cleansing The Common: A Narrative-Intertextual Study Of Mark 7:1-23, Eike Arend Mueller

Dissertations

The conflict story of Mark 7:1–23 between Jesus and the religious leaders over the issue of defilement is the meeting point of a variety of disciplines: Purity studies, Jewish studies, exegetical studies, Historical Jesus studies, and studies on Jesus and the law. The crux of the passage, the meaning of the parable in v. 15 and the ensuing “cleansing” in v. 19, has been interpreted very differently. Scholars doing exegetical studies and studies on the relationship between Jesus and the law have maintained that the Gospel writer correctly reflects in 7:19 the meaning of Jesus’ parable (7:15), abrogating the clean/unclean …

The Use Of Fantasy Theme Analysis To Describe The Group Communication And Creative Problem-Solving Skills Of University-Level Students As They Prepare For Destination Imagination Global Finals Competition, Elizabeth Morgan Armstrong

Dissertations

Problem and Purpose

In order to meet the growing needs for efficiency in the workplace, industry is turning to group-work and collaboration. Successful teams are in demand because they not only meet the efficiency needs, but also provide the kind of bonding that creates convergence in the members. The chemistry or recipe for this kind of success is difficult to pinpoint, however, and several aspects of group communication and skills, need to be re-examined using communication theory. The purpose of this study is to describe one of those aspects—group creative problem-solving—in order to see how the communication used in that …

Science Teaching And Learning As Transformation: Making Meaning With My Students, Megan Marie Leider

Dissertations

As a classroom science teacher, I have experienced firsthand the disengagement and disinterest students have with science. Students often struggle to retain information from year to year, feel comfortable in the science classroom, and see the connections between the science taught in the classroom and their lived experiences. It is obvious to me that we could do more for our students. One way in which to assist students with science learning is through the incorporation of Sci-YAR (Science Youth Action Research). Sci-YAR is a curricular framework and instructional strategy that places the student at the center of their learning. It …

The study analyzes data collected at a bathhouse over a seven day period beginning on June 9, 2014 and ending on June 15, 2014. The independent variables of HIV/AIDS complacency and substance use, along with the dependent variable of sexual risk behavior are examined through the lens of protection motivation theory. Protection motivation theory posits that response efficacy and threat appraisal influence how a person makes decisions. The implications and findings of the study related to direct …

Sexual Assault And Academic Achievement: Creating More Ideal College Campuses For Sexual Assault Survivors By Taking Into Account Intersectionality And Multiracial Feminism, Kelly Pinter

Dissertations

In this dissertation, the reader will learn about 28 sexual assault survivors' perceptions about educational and criminal justice responses to them after a sexual assault and how these sexual assault survivors perceived how race and ethnicity, income, and gender affect cases differently. Additionally, I explore sexual assault policies that survivors think are working, and those they feel need improvement. I also assess in depth recommendations concerning what education administrators, staff, and advocates can do to assist sexual assault survivors.

Shifting Narratives In Doctoral Admissions: Faculty Of Color Understandings Of Diversity, Equity, And Justice In A Neoliberal Context, Dian Drew Squire

Dissertations

Little is known about how faculty make decisions in the doctoral admissions process or how they conceptualize diversity, equity, and justice in those same processes. As the United States continues to diversify, understanding how students are selected into graduate programs and how faculty understand diversity, equity, and justice is increasingly important to supporting diverse leadership bodies and shaping an inclusive campus cultural context. This qualitative study utilized semi-structured interviews, focus groups, and critical discourse analysis to explore how faculty of color understand diversity, equity, and justice norms, values, and behaviors in the doctoral admissions process in Higher Education and Student …

The Trauma Thesis: Medical And Literary Representations Of Psychological Trauma In The Twentieth Century, Sarah Louise Eilefson

Dissertations

The historian Samuel Hynes has observed that World War I was not only the greatest military and political event of its time but also the greatest imaginative event. Soldiers and civilians struggled to comprehend the war’s devastation and the changes it produced while medical practitioners and artists examined the war as a site of extraordinary trauma. My project explores two of the many archives of trauma: the medical discourse through which trauma was defined; and representations of trauma in a variety of English language novels from the early and mid-twentieth century. I begin with a historical survey of the medical …

Daddy Is Involved: How Do African American Fathers Participate In The Education Experiences Of Their High School Children?, Gregory Pierre Baker

Dissertations

Parents have tremendous influence in the lives of their children. As a result, it is valuable to investigate how high school parents participate in their children's high school education experiences. African American fathers in particular, have been placed under scrutiny by the media and general population for not being involved in the education experiences of their children, while the research literature dispels this generalization.

This study investigates how African American fathers, in a suburban community, participate in the education experiences of their high school children. This research study took place at a Du Page County, Illinois, high school under the …

Public Relations: Diaspora, Media, And The State(S) Of American Literature, Nathan Allen Jung

Dissertations

Like any good public relations campaign, this dissertation aims to offer a persuasive interpretation of certain key facts. The facts, as I see them, are as follows: first, a great number of contemporary novels and poems explore the personal and social consequences of diasporic migration. Second, these texts, along with their print and electronic paratexts, share a pervasive interest in media. And third, these works are rarely read in conversation with one another, despite their mutual concern for migration and media. Owing to this last point in particular, scholarship has failed to fully address the broader media theories developed in …

Social Justice And Ecological Responsibility: A Moral Case For International Collaborative Action On Environmental Degradation And Climate-Induced Displacement, James Stephen Mastaler

Dissertations

The contemporary ecological crisis, manifest in human-induced climate change, is a powerful form of structural violence against the poorest communities on the planet. As such, my research resides at the nexus of structural poverty, gender disparity, ecological degradation, and climate-induced displacement. The social justice implications emerging from this nexus require responsible moral deliberation and discernment over the international community's role in minimizing the human tragedies accompanying forced displacement and migration. While asserting the interconnectedness and dependency of all life upon mutual flourishing, responsible decision-making expands the range of felt moral concern to include ecological flourishing. Social justice is only possible …

Emergent Literacy Skills In Print And Electronic Contexts: The Influence Of Book Type, Narration Style, And Attention, Kathryn Joyce O'Toole

Dissertations

Preschoolers can learn words and story content from traditional print books, but there has been no direct comparison of their learning from print and e-books while controlling for narration style. Additionally, very little empirical work has utilized a tablet e-book as the majority of research has examined learning from computer e-books. The current project examined how 4-year-olds (N = 100) learned words and story content from four different book reading contexts: a print book read aloud by a live adult, a print book narrated by an audio device, a tablet e-book read aloud by a live adult, or a tablet …

Somos Familia: Family As An Organizing Trope In 20th-21st Century Latina/O Literature, Victoria Anne Bolf

Dissertations

This dissertation examines various ways that family has been employed as a model of both oppression and liberation in Latina/o literature. Working from an interdisciplinary standpoint at the crossroads of literary and cultural studies, women’s, gender, and sexuality studies, Chicano/a studies, and Latino/a studies, this project seeks to uncover how representations of familia in U.S. Latino/a literary texts accomplish their discursive work, as well as complicating conventional formulations of kinship and family.

I examine Down These Mean Streets by Piri Thomas, in Chapter One, in terms of queer family and the counter-domestic logic of “the streets.” In Chapter Two, I …

Learning From The Un Preventive Deployment Mission In Macedonia: Nothing Fails Like Success?, Mary Frances Rosett Lebamoff

Dissertations

Preventive deployment as a conflict prevention tool has not recurred in the past decade-plus, despite the broadly acclaimed success of the United Nations Preventive Deployment in Macedonia (UNPREDEP 1995-1999; and its predecessor mission, UNPROFOR/Macedonia, UNPROFOR/M 1992-1995). The United Nations in particular has continued with mainly first- and second-generation peacekeeping, peacemaking and peacebuilding actions. What may best explain why has there has been no other engagement in preventive deployment missions, when there has been much emphasis placed formally and informally on early warning, detection, mitigation, and prevention of conflict? There have also been an increasing numbers of violent conflicts worldwide, so …

The Global Dystopian: Twenty-First Century Globalization, Terrorism, And Urban Destruction, Ryan Frank Peters

Dissertations

The new millennium has witnessed a staggering outpouring of literature, film and art which depict dystopian and post-apocalyptic societies. These stories have come in the form of massively popular films like the Matrix and Hunger Games trilogies; Emmy-winning television adaptations such as The Walking Dead; and Pulitzer Prize-winning novels like Cormac McCarthy’s The Road, or Kazuo Ishiguro’s Booker Prize-nominated Never Let Me Go. In the last five years, a wave of critically-lauded video games – The Last of Us, Bioshock Infinite, and Dishonored come immediately to mind—have depicted dystopian worlds while reaching mass audiences. Combined, The Last of Us and …

Effects Of Aggregated Alpha-Synuclein On Cultured Neuronal Cells, David Freeman

Dissertations

α-synuclein dysregulation is a critical aspect of Parkinson's disease pathology. Recent studies have observed that α-synuclein aggregates are cytotoxic to cells in culture and that this toxicity can be spread between cells. However, the molecular mechanisms governing this cytotoxicity and spread are poorly characterized. Recent studies of viruses and bacteria, which achieve their cytoplasmic entry by rupturing intracellular vesicles, have utilized the redistribution of galectin proteins as a tool to measure vesicle rupture by these organisms. Using this approach, we demonstrate that α-synuclein aggregates can induce the rupture of lysosomes following their endocytosis in neuronal cell lines. This rupture can …
