Appearance Over Function - The Impact Of Long-Term Oral Contraceptive Use On Brain Development, Breast Tissue Composition, And Future Lactation Outcomes, Fiona M. Wang

Dissertations

This integrative review examines the long-term effects of combined oral contraceptive (COC) use beginning in puberty on brain development, breast tissue composition, and future breastfeeding outcomes. Puberty is a critical developmental stage during which hormonal changes significantly impact the neurological and reproductive systems. The introduction of synthetic estrogen and progestin through COC use during this time may disrupt natural hormonal pathways, potentially altering neuroendocrine signaling and breast tissue maturation. Such changes may have lasting consequences, including impaired milk production, a weakened milk ejection reflex, disrupted maternal-infant bonding, and reduced overall breastfeeding success. The review synthesizes findings from endocrinology, neuroscience, and …

Challenges In Providing Equitable Education For Primary School Students With Learning Disabilities In Zimbabwe: Teachers’ Experiences., Joyce Madzinga

Moreover, the literature lacks insight into the lived experiences of children of immigrants, despite the increasing prevalence of this population.

This study aimed to address how children of immigrants experience cultural identity and belonging. A mixed methods research …

Racial Identity And Belonging Among Asian American Undergraduate Students In The Midwest, Seema M. Dahlheimer

Dissertations

Asian American students are often deemed overrepresented in higher education, leading to inequities in admissions, scholarships, and student support. This perception feeds and is fed by the model minority stereotype, which characterizes Asian Americans as hard-working and high-achieving and creates intense pressure to succeed academically (Poon et al., 2016). In addition, Asian American college students often experience racism and xenophobia, which can undermine their sense of belonging on campus. However, in the Midwest, where their immigration is more recent and conversations about race are often framed in terms of Black and white, Asian Americans often feel invisible and othered (Lee, …

The Residual Impact Of Slavery On How Enslaved Black Females Defined And Made Meaning Of Sexual Violence: A Content Analysis, Suzanne R. Bates

Dissertations

Thompson-Miller & Picca (2016) and Feimster (2023) argued that enslaved African American women, and even free African Americans after the Civil War were victims of non-consensual sexual activity and rape. The NISVS report revealed that before the age of 18 years old, 35.5% of African American women experienced contact sexual violence, 29.5% experienced non-contact unwanted sexual encounters, and 20.7% experienced rape (Basile et al., 2022). Researchers of slave scholarship have made the case for the importance of including discourse on slavery and enslaved Black females’ experiences when discussing present day sexual violence among Black women in the US today (Balfour, …

Precarious Privilege: Exploring The Intersection Of White Teacher Habitus And Social Justice In International Schools, Kevin L. Workman

Dissertations

This qualitative study explored the underresearched phenomenon of White teacher allyship within an emergent diversity, equity, inclusion, and justice (DEIJ) movement in international schools.

Evaluation Of Prerequisite Discrimination Skills For Obtaining Assent From Individuals With Intellectual Disabilities: A Translational Study, Jessica J. Helen Detrick

Dissertations

Assent can be defined as an individual’s affirmative agreement to participate and should be obtained by those who cannot consent (i.e., children and adults deemed as “incapable”) when conducting research or providing services. Federal policies recommend considering age, maturity, and psychological state to determine if a participant can assent. Beyond these considerations, there is little guidance. However, practitioners and researchers still have an ethical obligation to obtain assent. Morris and colleagues (2021) conducted a literature review of assent procedures documented within behavior-analytic journals and found few studies. Of the procedures identified, many would likely be difficult to implement with participants …

Immune Modulation Affects Olfactory Glomerular Recovery In Zebrafish, Bonnie E. Ebendick

Dissertations

Adult zebrafish regenerate neurons throughout their lifetime and exhibit rapid recovery from neuronal damage with support from their immune system, making them an excellent model for studying neuroinflammation and brain repair mechanisms. When olfactory sensory neurons are lesioned, their cell death stimulates the immune system by activating microglia and other immune cells in the olfactory bulb, initiating tissue repair and neuronal replacement. This dissertation investigates how the immune system influences recovery from neuronal damage, testing the hypothesis that immune perturbation in zebrafish alters neural recovery.

To investigate the link between immune function and neuronal regeneration, zebrafish received a unilateral lesion …
