Preparing To Break Barriers: A Mixed Methods Exploration Of The Knowledge, Attitudes, And Perceptions Of Hiv, Prep, And Hiv Risk Behaviors Among Women Of Color In Miami, Florida, Amanda C. Ichite

FIU Electronic Theses and Dissertations

The U.S. HIV epidemic is characterized by regional, racial, and ethnic disparities. HIV rates are disproportionately higher in the South and Black and Hispanic populations are most impacted. Moreover, the intersectional identity of being a Black or Hispanic woman living in the South has been associated with profound disparities in HIV impact. Prior to the advent of the biomedical HIV prevention tool pre-exposure prophylaxis (PrEP) in 2012, women were limited in their options for female-controlled HIV prevention strategies. Despite the proven efficacy of PrEP, utilization in women is significantly lower than other at-risk groups. In the present study, secondary analysis …

The Politics Of The Self: Psychedelic Assemblages, Psilocybin, And Subjectivity In The Anthropocene, Joshua Falcon

FIU Electronic Theses and Dissertations

This dissertation examines how psychedelic substances become drawn into particular sociohistorical and political arrangements, and how psychedelic experiences with psilocybin ‘magic mushrooms’ are used as tools of subjectivation. Guided by literatures in philosophy, critical theory, and the social sciences that focus on subjectivity, assemblage theory, and critical posthumanism, I argue that psychedelics are drawn into variegated assemblages, each of which conceptualizes the nature of psychedelics in highly specific ways that reflect implicit conceptions of the world and the self. In developing the concept of psychedelic assemblages, this research provides a window onto the politics of the self in the Anthropocene. …

The Impact Of Hiv-Related Stigma On The Racial/Ethnic Disparities Across The Hiv Care Continuum Among Adults Living With Hiv In Florida, Derrick James Forney

FIU Electronic Theses and Dissertations

Background: Florida currently has one of the highest rates of new HIV infections in the U.S. As of 2019, Black and Hispanic HIV-positive individuals in Florida were significantly less likely to receive HIV care, remain in care, and achieve viral suppression than white HIV-positive individuals. Several studies have linked HIV-related stigma to poor outcomes among people living with HIV (PLWH). This study examined the impact of distinct HIV-related stigma subtypes on linkage to care, retention in care, and viral suppression among PLWH in Florida and if these associations differed across race/ethnicity.

Methods: Data from the 2015-2017 Florida Medical Monitoring Project …

The Developmental Plasticity Of Fruit Fly Vision, John Paul Currea

FIU Electronic Theses and Dissertations

In this dissertation we explore the morphological and neural plasticity underlying vision at different scales—within and between species of Drosophila—to elucidate the role of eye development in the evolution of vision. In chapter 2, we offer a tool to accelerate large-scale research into compound eye morphology, and validate it on the eyes of several insect orders and image media. Then, in chapter 3 we demonstrate the developmental plasticity of eye morphology and neural summation in fruit flies, finding an interesting interplay between the two systems. In chapter 4, we elucidate the role of visual plasticity and neural summation in the …

Associations Of Sociocultural Stressors With Psychological Distress And Self-Rated Health Among Hispanic Emerging Adults, Abir Rahman

FIU Electronic Theses and Dissertations

Emerging adulthood (18-25 years) is a distinct period of life, characterized by a high level of instability in the matters of romantic life, work, and challenging developmental undertakings. Various events related to these developmental tasks may leave lifelong impacts on emerging adult’s identities and health across adulthood. Further, due to the unstable nature of this period, individuals in this age group are vulnerable to various mental health problems. Hispanic emerging adults may be particularly at risk of experiencing adverse health outcomes, as on top of normative developmental stressors (e.g., increased autonomy, finding employment), they are often exposed to various chronic …

The Cerebellum's Relationship To Language Function Following Perinatal Stroke, Carolina Alexis Vias

FIU Electronic Theses and Dissertations

While recent studies have demonstrated the association between the cerebellum and higher-order cognitive functioning, it is still unclear how volumetric differences of specific regions of interests within the cerebellum across typical and atypical development are related to language function. We have done so by measuring the volume of cerebellar subregions of healthy controls, and compared the volume to behavioral measures of language function. We then followed with an analysis of the cerebellum’s relationship to language function following perinatal stroke, which provides us with a greater knowledge of the impact of a cortical injury on cerebellar development and the cognitive outcomes …

Prefrontal Pathways Provide Top-Down Control Of Memory For Sequences Of Events, Maanasa Jayachandran, Stephanie B. Linley, Maximilian Schlecht, Stephen V. Mahler, Robert P. Vertes, Timothy A. Allen

Department of Psychology

We remember our lives as sequences of events, but it is unclear how these memories are controlled during retrieval. In rats, the medial prefrontal cortex (mPFC) is positioned to influence sequence memory through extensive top-down inputs to regions heavily interconnected with the hippocampus, notably the nucleus reuniens of the thalamus (RE) and perirhinal cortex (PER). Here, we used an hM4Di synaptic-silencing approach to test our hypothesis that specific mPFC→RE and mPFC→PER projections regulate sequence memory retrieval. First, we found non-overlapping populations of mPFC cells project to RE and PER. Second, suppressing mPFC activity impaired sequence memory. Third, inhibiting mPFC→RE and …

Exploring The Neural Mechanisms Of Physics Learning, Jessica E. Bartley

FIU Electronic Theses and Dissertations

This dissertation presents a series of neuroimaging investigations and achievements that strive to deepen and broaden our understanding of human problem solving and physics learning. Neuroscience conceives of dynamic relationships between behavior, experience, and brain structure and function, but how neural changes enable human learning across classroom instruction remains an open question. At the same time, physics is a challenging area of study in which introductory students regularly struggle to achieve success across university instruction. Research and initiatives in neuroeducation promise a new understanding into the interactions between biology and education, including the neural mechanisms of learning and development. These …

Identifying And Intervening On Neural Markers Of Attention To Threat In Children With Anxiety Disorders, Michele Bechor

FIU Electronic Theses and Dissertations

Objective: Attention Bias Modification Training (ABMT) for anxiety aims to train attention away from threatening stimuli and toward neutral stimuli. Although ABMT shows promising anxiety reduction effects in children and adolescents, no study has examined its influence on neural indicators of attention measured using event-related potentials (ERPs) in children or adolescents (i.e., youths). The present study examined the influence of ABMT on the P1, N170, P2 and P3 ERP components during completion of the emotional faces dot probe task in youths with anxiety disorders who failed to respond to cognitive behavioral therapy. Method: Thirty youths (M age = 11.97, …

Antenatal Stressful Life Events And Postpartum Depression In The United States: The Role Of Women’S Socioeconomic Status At The State Level, Soumyadeep Mukherjee

FIU Electronic Theses and Dissertations

The purpose of this dissertation was to examine patterns of antenatal stressful life events (SLEs) experienced by women in the United States (U.S.) and their association with postpartum depression (PPD). It further explored the role of women's state-level socio-economic status (SES) on PPD; the racial/ethnic dispartites in SLE-PPD relationship; and the role of provider communication on perinatal depression.

Data from 2009–11 Pregnancy Risk Assessment Monitoring System (PRAMS) and SES indicators published by the Institute of Women’s Policy Research (IWPR) were used. Latent class analysis (LCA) was performed to identify unobserved class membership based on antenatal SLEs. Multilevel generalized linear mixed …

Examining The Impact Of Resilience On Work Stress And Strains In Nurses, Julie J. Lanz

FIU Electronic Theses and Dissertations

To address commonly cited organizational and personal outcomes in the nursing industry, it is important to identify factors that may mitigate the relationship between workplace stressors and strains such as turnover intentions, job satisfaction, burnout, and injuries. The purpose of the current study is to explore the role of trait resilience on the emotion-centered model of job stress in a sample of U.S. nurses. The study uses a multiwave design to examine the mitigating role of trait resilience on work strains in nurses.

Exploring The Development Of Social Responses In Children With Callous And Unemotional Traits: An Examination Of The Impact Of Hypothesized Reinforcing And Aversive Stimuli, Andre Maharaj

FIU Electronic Theses and Dissertations

Callous and unemotional (CU) traits in children with conduct problems have been indicated as precursors to adult psychopathy. The analysis of the sensitivity to rewards and punishment in this population may be useful in the identification of effective behavior modification programs and particularly the delineation of ineffective punishment procedures. Scores on the Child Psychopathy Scale, Inventory of Callous and Unemotional Traits, Contingency Response Rating Scale and the Sensitivity to Reward Sensitivity to Punishment – Children Revised scale were used to evaluate 20 children, aged 7-13, recruited from FIU’s Center for Children and Families. The sample comprised 14 males and 6 …

Perceptions And Experiences Of Intimate Partner Violence Among Hispanic College Students, Racquel Vera

FIU Electronic Theses and Dissertations

Intimate partner violence (IPV) is recognized as a serious, growing problem on college campuses. IPV rates among college students exceed estimates reported for the general population. Few studies have examined the impact of IPV among the Hispanic college student (HCS) population or explored how HCSs perceive and experience IPV.

Focusing on young adults (ages 18 to 25 years), this mixed methods study was designed to explore the perceptions and experiences of IPV focusing on levels of victimization and perpetration in relation to gender role attitudes and beliefs, exposure to parental IPV, acculturation, and religiosity. A sample of 120 HCSs was …
