Supporting Underprepared Writers In An Academic Success Program, Alison Ersheid
Supporting Underprepared Writers In An Academic Success Program, Alison Ersheid
Theses and Dissertations
For decades, colleges and universities have been grappling with the task of closing the readiness gap for underprepared writers entering the higher education system. Traditional developmental education models are costly and inefficient at best, and detrimental to the matriculation of students at worst. Bridge programs have had moderate success, but at a high price tag. Within the last decade, alternate approaches to developmental education, such as accelerated and corequisite models, have emerged. While these approaches have demonstrated success in improving overall student proficiency and confidence, little is known about the specific mechanisms and environments that promote success and improve writing …

Covid-19 has caused a rise in mental health issues, and focusing on social-emotional learning can help students learn the skills they need to lead healthy, successful lives. Teaching social-emotional skills in pre-K and kindergarten can provide students with these important skills in their formative years. In this convergent mixed-methods design study, the researcher explored the self-efficacy beliefs and attitudes of teachers towards using classroom read-alouds to teach social-emotional learning, and how those teacher self-efficacy beliefs and attitudes relate to the amount of time they spend on classroom read-alouds for social-emotional learning. Guided by Social Learning and Self-Efficacy theories, the researcher …
Evaluation Of Microglia’S Structural Variations Within An Organotypic Hippocampal Slice Model After Regionalized Toxic Injury, Jesus Antonio Trejos
Evaluation Of Microglia’S Structural Variations Within An Organotypic Hippocampal Slice Model After Regionalized Toxic Injury, Jesus Antonio Trejos
Theses and Dissertations
The dendritic cells of the CNS, the microglia (MG), are an initiation point of the immunological response within the post blood-brain barrier (BBB) compartment. Microglia morphology drastically changes in response to cell stress to a much different non-dendritic morphology. This investigation postulates that if the first MG responses to toxic injury are isolated and studied in greater morphological detail there is much to be learned about MG metamorphosis from a baseline (M2) to an activated (M1) state. The organotypic hippocampal slice was the experimental setting used to investigate microglial response to toxic injury. This isolates dendritic cellular responses and associated …

Interplay Between Rna Editing And Alternative Splicing Modulates Biophysical And Pharmacological Properties Of The Ion Channel Cav1.3, Willy Munyao
Theses and Dissertations
Alternative splicing and adenosine-to-inosine (A-to-I) RNA editing are post-transcriptional mechanisms that promote proteomic diversity in the brain. The impact of RNA editing on brain physiology is underscored by its association with the etiology and pathogenesis of various neurological and neurodegenerative diseases. Alternative splicing of exon 43 within the CaV1.3 C-terminus produces long (CaV1.3L) and short (CaV1.343S) variants exhibiting distinct gating and pharmacological properties. While the physiological role of CaV1.3 A-to-I RNA editing in brain function is still unfolding, recent findings indicate that unedited CaV1.3 channels display larger calcium influx and enhanced neuronal excitability, suggesting that A-to-I RNA editing may act …

Clinicians read a vignette of a terminally ill patient who is presenting as distressed and reporting several different irrational beliefs. Clinicians were then asked about their …
Does Dbt-Informed Treatment Address Comorbid Symptoms Of Social Anxiety For Adolescent Eating Disorder Patients In A Day Program? Exploring Emotion Regulation As A Mechanism For Change, Megan Bisanzo
Theses and Dissertations
Eating disorders, such as Anorexia Nervosa (AN) and Bulimia Nervosa (BN), often begin in adolescence and can be extremely challenging to treat effectively (Dawson, 2018; Martin & Golden 2014; Robatto et al., 2024). Eating disorder behaviors such as acute caloric restriction, excessive exercise, binging and purging can cause dangerous medical complications, while comorbid psychological conditions can lead to suicidal ideation and self-harm behaviors (American Psychiatric Association, 2022; Dancyger & Fornari, 2005; Martin & Golden, 2014). Social anxiety is one such comorbid disorder that can be a barrier to patients fully engaging in treatment (Goodwin & Fitzgibbon, 2002; Smith, 2018). Deficits …

A similar relationship was found when looking at the long-term impact of changing irrational beliefs on emotional and …
Acculturative Stress, Depression, & Anxiety Among Arab Americans, Sally Kafelghazal M.S.
Acculturative Stress, Depression, & Anxiety Among Arab Americans, Sally Kafelghazal M.S.
Theses and Dissertations
Arab Americans, those who themselves or their ancestors have immigrated fromthe Middle East or North Africa to the United States, experience a lot of stress as a result of balancing varying cultures, known as acculturative stress. Due to the underrepresentation and misrepresentation of Arabs in Americans, as well as the taboo that exists in the Arab culture regarding poor mental health and seeking mental health services, the mental health impacts of acculturation stress among this population are scarcely studied. This dissertation aims to further understand ways in which acculturative stress impacts early generational Arab American adults, including immigrants and refugees, …
Modeling The Burden Of Racial Discrimination And Its Effects On Anger Coping: A Latent Profile Analysis, Brandon Dial
Modeling The Burden Of Racial Discrimination And Its Effects On Anger Coping: A Latent Profile Analysis, Brandon Dial
Theses and Dissertations
Purpose: Perceived racial discrimination (PRD) is defined as unfair treatment received because of one’s race. Although prior research has established that PRD is a chronic psycho-social stressor with various subdimensions, there is less research exploring whether unique profiles or clusters of discriminatory experiences exist. Further, although research has identified positive relations between discrimination and anger suppression and expression, it is not known if profiles of discriminatory experiences are differentially linked to patterns of anger expression (i.e., anger suppression, outward anger expression, or anger control). Therefore, the aim of this study is to identify profiles of discriminatory experiences in a sample …
Synthesis Of Leishmania Spp Antigens For The Development Of Vaccine Candidates, Dipesh Budhathoki
Synthesis Of Leishmania Spp Antigens For The Development Of Vaccine Candidates, Dipesh Budhathoki
Theses and Dissertations
Leishmaniasis is a neglected tropical disease caused by the protozoan parasite of the genus Leishmania. Presently no vaccine against Leishmaniasis is available, so there is a need for new anti-leishmanial treatments, including an effective preventive vaccine. We focus on developing vaccine candidates based on leishmania’s cell surface carbohydrate antigens. Saccharides heavily envelop the cell surface of Leishmania, lipophosphoglycan (LPG) becoming a significant glycan in most leishmania species. Its intrinsic antigenicity makes this polysaccharide a useful target for developing conjugated vaccine candidates against all leishmaniasis variants. In this report, we present our progress towards the synthesis of the fragments of LPG …
