Oncolytic Tanapoxvirus Recombinants Expressing Mil-2, Flagellin-C, And Mccl2 Regress Human Cancer Xenografts In Immune Deficient Nude Mice And Immune Cell Reconstituted Balb/C Nude Mice., Michael Leonard Monaco

Dissertations

Tanapoxvirus (TPV) is a double stranded DNA virus from the genus Yatapoxvirus which has been engineered for the purpose of potentially treating a number of human cancers. Previous studies have shown TPV recombinants are capable of inducing tumor inhibition and even regression in athymic nude mice bearing human cancer xenografts of colorectal, melanoma and triple negative breast cancer (TNBC). However, TPV is host-restricted to humans and monkeys, including cancerous cells, which has provided a unique obstacle in its development as an oncolytic virus (OV). Namely, standard syngeneic mouse models cannot be used as test systems to evaluate TPV’s efficacy against …

Analysis Of Trauma Screening As A Potential Predictor Of Congregate Care Placement As A Key Factor In Caseworker Decision Making, Amy Louise Perricone

Dissertations

The placement of foster care children into congregate care (CC) facilities has been debated regarding whether CC can provide safety and healing, or if it is harmful and retraumatizing to children. In recent years CC has come under scrutiny due to high per diem costs and increasing reports of abuse and even death of children. In response, the federal Families First Prevention Services Act (FFPSA) was enacted in 2018 with a goal of reducing the number of children in CC. Since then, efforts have been implemented nationwide to achieve this goal. This study explored the value of statewide trauma screening …

The Effects Of Adolescent Trauma, Mental Health Treatment, And Demographic Variables On Educational Outcome, Christopher Postema

Dissertations

Poor educational performance in adolescence can occur due to trauma, substance use, or other stressors. This study used conflict theory as a foundation, suggesting differences in educational outcomes can be attributed to systems perpetuating the current power structures that cause inequality in academic opportunities and performance. Trauma in adolescence can have adverse effects on educational outcomes and emotional stability. Research suggests that mental health therapy as well as a reduction in trauma symptoms can improve educational outcomes. Race, gender, substance use, socioeconomic status, and employment are important variables that could influence educational outcomes. Interaction terms were found in the literature …

The Effect Of A Specialized Training Program On The Knowledge And Attitudes Of First Responders About People With Communication Disabilities, Mariesa Rang

Dissertations

Individuals with disabilities experience emergencies more often than those without disabilities, and individuals with complex communication needs (CCN) are even more likely to have these experiences. As a result of experiencing both medical and legal emergencies, individuals with CCN have frequent encounters with emergency first responders (i.e., firefighters, EMS, and police officers; EFR). Despite being well-trained in many facets of their occupation, EFRs are not adequately trained for working with this vulnerable population. This may lead to less-than-optimal outcomes for individuals with CCN.

To better equip EFRs in their efforts to assist individuals with CCN, a 90-minute training session was …

Antiracist School Counseling Pedagogy: A Quasi-Experimental Multiple Regression Analysis, Star L. Zetocha

Dissertations

America’s K-12 schools, which were initially created exclusively for White children, are racialized institutions (Spring, 2019). School counseling ethics now obligate school counselors to engage in antiracist praxis in schools, yet school counselors-in-training (SCITs) are not typically provided with explicit training in antiracism, which allows them to enter the field with colorblind racial attitudes that inhibit them from recognizing and confronting racism in schools (Gibson & Fripp, 2022). The purpose of this research was to examine the relationship between colorblind racial attitudes and antiracist behaviors of school counselors in-training who had and had not taken an antiracist school counseling course. …

An Analogue Study Of Expected Working Alliance And Hope With Victims Of Military Sexual Trauma Among Civilian And Military-Oriented Therapists, Alishia D. Salyer

Dissertations

Victims of military sexual trauma (MST) face unique challenges as they pursue mental health treatment and supportive care. Understanding what factors impact potential treatment outcomes is critical in aiding in their recovery (Castro et al., 2015; Kroviak, 2020). Although a substantial amount of research has been conducted to evaluate prevalence and client factors associated with treating victims of MST (Teit et al., 2015; Turchik & Wilson, 2010), little is known about therapists’ factors including therapists’ expectations working with such clients. The purpose of this study was to examine the relationships between therapist type (military-affiliated versus civilian), therapist gender, client gender, …

This study describes those cases of beginning a teaching career with little to …

The Effect Of Maternal Obesity On The Regulation Of Gene Expression And Cell Fate During Embryonic Cortical Neurogenesis, Thilina Thejinda Alawathugoda

Dissertations

Neurodevelopmental disorders have their roots in multifaceted origins that manifest during the earliest stages of embryonic growth, often linked to sophisticated gene regulation dynamics. A perturbed metabolic environment, specifically owing to maternal obesity, can lead to dyslipidemia, subsequently threatening the optimal development of the embryonic central nervous system. Growing evidence suggests that such metabolic irregularities during pregnancy can alter neurogenesis pathways, thus predisposing the developing fetus to neurodevelopmental disorders. One of the primary avenues through which these disruptions may occur is through alterations in histone modifications resulting from fluctuations in the expression of histone modifying enzymes or the availability of …

Opportunity That Transforms Lives: Exploring The Lived Experience Of Graduates From A New Community College In The Dominican Republic, Sally Joslyn Peña Martinez

Dissertations

This qualitative study explored the lived experiences of graduates from a recently established community college in the Dominican Republic (DR). The study sought to understand from graduates' perspective the influence of completing an associate degree at the first Dominican Community College, Instituto Técnico Superior Comunitario (ITSC), and if their experience was transformative. Enrolling in higher education initiates a potentially transformative journey, consciously or unconsciously (Taylor et al., 2000). These changes stem from personal reflections on new experiences, forming new beliefs and assumptions that infill life with new meaning (Brookfield, 1984; Mezirow, 1978). This phenomenon is evident in community college students …

A Framework For Flourishing: Belonging, Confidence, And Connectedness In Academic Libraries, Kathleen Anne Langan

Dissertations

Academic libraries support students to be successful in their lives post-graduation by adopting more human-centered missions, visions, and measurable outcomes Support and success in this sense means developing programmatic outcomes that bolster the concepts of human flourishing – potential and purpose – that drive students toward happiness in their personal, professional, and civic lives.

Bisexuality, Biphobia, And Its Effects On Sexual Identity, Religious Identity And Mental Health: Examining Clinical Implications, Diana Ramirez

Dissertations

Bisexuality is a sexual orientation, sometimes known as “bi,” that includes sexuality in which certain people are attracted to more than one sex and gender. Bisexuality differs from other sexual- and gender-nonconforming experiences (McInnis et al., 2022). According to Ross et al. (2018), bisexuality is frequently described as an invisible sexual orientation, and only in the last 20 years has research on biphobia and bisexuality increased (McInnis et al., 2022). Experiences unique to bisexuality include bisexual invisibility from a societal level (Dyar et al., 2015), bisexuals are more prone to experience sexual orientation instability (Bostwick et al., 2014), and bisexual …

Post-Pandemic Student Attendance, Becki Delloyd

Dissertations

Student attendance has been a national concern since the start of compulsory education in America; however, since the COVID-19 pandemic, attendance plummeted to never- before-seen attendance rates. Nationally, by the end of the 2021-2022 school year, nearly one in three students were absent 10% or more of the school year (Attendance Works, 2023). My 39-question survey conducted in two vastly different states between April and May of 2023 corroborated the national data and resulted in nearly one in three students being absent 10 or more school days in a year. Through my study, I explored parents’ perceptions of post-pandemic K–12 …

Self Portraits: How The Arts May Be The Key To Equitable And Authentic Engagement For Culturally And Linguistically Diverse Student Populations, Betsy Sostak

In this study, I explore the ways in which educational equity may be achieved to a …

Chronic Stressors, Obesity Pathogenesis, And The Moderating Effect Of Internalized Weight Stigma; A Quantitative, Illinois Study, Karyn Byrne

Dissertations

The obesity epidemic is a ‘wicked’ problem with a complex web of determinants and outcomes. While generally higher for minoritized populations, prevalence rates manifest in surprising, nonlinear patterns. There is no consensus regarding treatment protocols or mitigation efforts, except that current efforts remain largely ineffective. Much research evidence that a profusion of determinants of health support obesity pathogenesis through various physiological processes and mechanisms, including the allostatic load, mitochondria functioning, the gut microbiome, and epigenetics. Intervening to support markers of the allostatic load (immunity, inflammation, and metabolic health) may provide a more effective treatment outcomes than traditional approaches, which tend …

Principals’ Leadership Of The Integration Of The Neurosequential Model In Education, Alison Grace Ostrom

Dissertations

The impact of childhood trauma on students in schools has become a relevant issue for today’s school leaders in the United States (Mendelson et al., 2015). The effects of trauma often interfere with students’ ability to learn and manage the demands of a school environment. Students are coming into schools with diverse academic, behavioral, and social-emotional needs, which has led school leaders to adopt trauma-informed approaches and programs in schools (Rossen, 2020). There are many trauma-informed programs available to school principals, one of them being the Neurosequential Model in Education (NME). This particular approach connects trauma-informed practices to neurobiological principles …

Individual Differences In Numerical And Verbal Abstraction And The Ability To Draw Inferences From Text, Anna Christine Johnson

Dissertations

Abstraction may be defined as the process of isolating commonalities from a series of examples. Numerical estimates (e.g., Brown & Siegler, 2001), prototypes (e.g., Posner & Keele, 1968), and scripts (e.g., Schank & Abelson, 1977) are forms of abstract representations. Abstraction may differ across individuals, with some relying more on memorizing individual examples than on forming abstract representations, or vice versa. McDaniel et al. (2014) elucidated this abstractor vs. memorizer distinction and developed a function learning task to categorize individuals. Subsequent research has explored this distinction as it applies to transfer, the application of previously learned knowledge to new situations …

An Investigation Into What Contributes To High Rates Of Preschool Inclusion In Rural Kansas School Districts, Lena Mae Kisner

Dissertations

The inclusion of Kansas preschoolers with developmental delays in general early childhood environments has shown little growth over the past seven years. An initial examination of public data for federal fiscal years 2018, 2019, and 2020 showed inclusion rates in preschools in Kansas public school districts differed by special education administrative configuration (SEAC). Kansas uses three different types of SEACs (i.e., single district, special education cooperative, and interlocal). The special education cooperative (also known as cooperative) and interlocal SEACs had the lowest rates of inclusion in preschools and highest proportion of rural school districts. Despite the lower rates of inclusion …
