Resilience As A Mediating Factor For Behavioral And Academic Outcomes For Adolescents With Executive Functioning Impairments, Bronwyn Louise Lehman

Dissertations

Executive functioning (EF) and resilience have become topics of interest in psychology and education as being key components in determining a person’s ability to engage meaningfully and effectively within their environment as well as a reason for better than expected outcomes. The purpose of this study was to examine whether self-reported resilience factors could account for certain behavioral, adaptive, and academic outcomes for adolescents in the presence of executive functioning difficulties. Mediation analysis was utilized to determine resilience (measured using the Journey to Wellness scale) as a mediating factor for academic and behavioral outcomes (measured using select subscales on the …

Photoreception And Eye Regeneration Mechanisms In Planarians, Taylor R. Birkholz

Dissertations

Although humans lack the ability to regenerate complete organs and limbs following amputation or injury, there are many other species (both vertebrates and invertebrates) that can. Significant advances have been made in understanding the genetic mechanisms that regulate organ regeneration in these species, including regeneration of eye tissues such as the lens and retina. Planarians are an established historical model used to study regeneration due to their ability to regenerate any organ, including the eye. With recent advances in molecular genetic analyses, planarians are now an emerging model for the specific study of eye regeneration mechanisms. Furthermore, regeneration of the …

The Place Of Art In Black Panther Party Revolutionary Thought And Practice: From Revolution To Reform, A Content Analysis, Michael James Macaluso

Dissertations

The Black Panther Intercommunal News Services (BPINS) was one of the most powerful black presses and a mechanism to build an imagined political community. Unfortunately, the scholarly and sociological literature examining the artwork of the Black Panther Party published in BPINS has been inadequate. Most work to date focuses solely on one artist, Emory Douglas, the Party’s Minister of Culture and primary editor of their press. Many other artists contributed to the collective endeavor of art and organization at large. The artwork of the Black Panther Party was a communal enterprise geared toward the promotion of political consciousness through visual …

Color-Blind Racial Ideology, Social Justice Attitudes, And Cultural Competency In U.S. Medical Students And Resident Physicians, Jennifer G. Hahm

Dissertations

Health disparities disproportionately affect the lives of racial and ethnic minorities in the United States (Agency for Healthcare Research and Quality, 2015; U.S. Department of Health and Human Services NHQR, 2013). Social conditions, social determinants, and structural inequities have been acknowledged as influential forces on minority health (Link & Phelan, 1995; World Health Organization, 2011). Focusing on eliminating environmental and social conditions affecting the health status of racial and ethnic minorities should be a prerogative for healthcare professionals in reducing health disparities. The purpose of this study is to examine the relationship between color-blind racial ideology and social justice attitudes …

Finite Element Modeling And Experimental Characterization Of Knot Configuration Effect On The Mechanical Performance Of Surgical Suture, Arz Y. Qwam Alden

Dissertations

Tendon injuries in orthopedic surgery and sports medicine are escalating; hence there is great interest in improving tendon repair. The integrity of tendon repair depends in part on a combination of suture material, suture size and knot configuration. Recent studies have indicated the failure of surgical knots as a failure mode during surgical repair. Further, there is still no consensus on the ideal (best/safest) surgical knot techniques. Also, this failure mode is related to stress concentrations, which cannot be easily established with traditional tensile testing. Most researchers have focused on the measurement and comparison of the gross structural response of …

Do Zebrafish Exhibit A Placebo Response? Fluoxetine Conditioning In Chronically Stressed Adult Zebrafish (Danio Rerio), Kanza M. Khan

Dissertations

Placebo responses are a widely observed phenomenon in humans and animals alike. In humans, placebo responses are largely attributed to expectancy processes, and conditioning (Stewart-Williams, & Podd, 2004). In the clinical setting, the placebo response is very useful as it has the power to improve physical and/or psychological states, without the need for treatment with a higher drug dose. In clinical trials however, researchers must control for potential placebo effects. Still, despite the experimental control, placebo responses are widely observed during phase 2 and phase 3 clinical trials, resulting in a weak drug effect. In the effort to improve the …

Exploring Temperament In Beluga Whale Calves (Delphinapterus Leucas), Beri Brown

Dissertations

Studies of personality and temperament in humans span many disciplines, although animal research is still relatively undeveloped. Research investigating stable individual differences in marine mammals has been limited, and to date there have not been any studies with beluga whales. As an ongoing longitudinal study, seven beluga calves, housed at SeaWorld San Antonio, were videotaped throughout their first two years of life. Four videos were selected from archived video recordings for each calf from the following nine phases: newborn phase (month 1), Q1 (month 2-3), Q2 (month 4-6), Q3 (month 7-9), Q4 (month 10-12), Q5 (month 13-15), Q6 (month 16-18), …

Structural Model Of Child Routines And Self-Regulation In Relation To Parenting And Externalizing Behavior Problems In Young Children, Lovina R. Bater

Dissertations

The relationship between parenting practices and externalizing behavior problems in preschool children is well established; however, the mechanisms that explain this relationship are less understood. It is suggested that the structure and predictability created by child routines allow children the opportunity to become aware of and learn to regulate their behaviors accordingly, yet only a couple of studies have examined this relationship. Therefore, this study examined competing models (i.e., direct, indirect, and serial mediation models) to help determine which model captures the relationship between the variables of interest. It was hypothesized that each model would have good model fit but …

An Analysis Of Prey Resistance And Long-Term Temporal Changes In Venom Composition Within Rattlesnake Populations, Thomas Michael Mccabe

Dissertations

Venoms are complex mixtures of toxic constituents used by venomous snakes to incapacitate prey, to defend against threats, and to aid in pre-digestion of prey items. Snake venoms vary based on a number of characteristics, including but not limited to individual identity, species, geographic range, and ontogeny. While much is understood about snake venom variability, relatively little is known as to how venom changes or is stable through time. This doctoral dissertation focuses on elucidating the nature and mechanism of compositional change in the venoms of two rattlesnake species, the Northern Pacific Rattlesnake (Crotalus oreganus oreganus) and the Desert Massasauga …

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 …

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 …

A Case Study On The Experiences Of Black Men Participating In An African-American Male Initiative At A Post-Secondary Institution, Michael A. Gibson

Dissertations

In the United States, African-American men are dominant in the entertainment industry mainly in sports and music. However, their success in entertainment does not translate to education. Many Black men grow up not having a positive experience in education, thus they do not see its value. However, many see the value in striving after a false sense of masculinity comprised of sex, drugs, money, and crime. This research was conducted to see how effective Black male mentorship through an African-American Male Initiative could be for Black males in a post-secondary institution in providing the positive experience in education that they …

Urban Food Entrepreneurship, Governance, And Economic Development In The Post-Industrial Cities Of Newark, New Jersey And Dayton, Ohio, John C. Jones

Dissertations

The local governments of post-industrial cities in the US struggle to foster economic development and to find uses for underutilized or abandoned urban land and buildings. Partly in response to growing consumer interest in locally produced foods, food entrepreneurs are increasingly using these underutilized urban properties for farming or for producing value-added food products. However, sometimes intentionally and sometimes unintentionally, existing policies and regulatory regimes of local and state governments often restrict the ability of urban food entrepreneurs to grow. This dissertation documents urban food entrepreneurship in the post-industrial communities of greater Newark, New Jersey and greater Dayton, Ohio. The …

Temporal And Spatial Effects Of Shock Overpressure On Blood-Brain Barrier Permeability In Blast-Induced Traumatic Brain Injury, Matthew Joseph Kuriakose
