Intimate Partner Violence In Post-Conflict Communities: The Case Of Peru, Karen Eliana León Negreiros

Theses and Dissertations

Intimate partner violence (IPV) is a major public health issue worldwide and the most common type of violence experienced by women. In the last decade, a growing number of studies have evidenced that situations of civil conflict, post-conflict, and displacement can significantly exacerbate IPV and increase the likelihood of experiencing IPV later in life. This study expands on the literature by taking a Geographic Information System (GIS) mapping approach to understand how civil conflict violence in Peru (1980-2000) is associated with IPV rates in the country, 4 years (2004) and 19 years (2019) after the conflict. Study results evidence the …

Child-Caregiver Relational Closeness And Child Mental Health In Nonparental Care Settings, Amanda Stafford Mcrell

Theses and Dissertations

This dissertation examines child-caregiver relational closeness and child mental health within nonparental care systems in Low- and Middle-Income countries (LMICs). Five key factors impacting the well-being of orphaned, separated, and vulnerable children in LMICs are explored using the Positive Outcomes for Orphans (POFO) dataset: child maltreatment, social support, child-caregiver relationships, and nonparental care systems. First, I examined the relationship between maltreatment, social support, and mental well-being. Findings showed that maltreatment was associated with lower mental well-being, where social support (emotional support, tangible support, positive social support) was associated with greater mental well-being, even in the concurrent presence of maltreatment. Second, …

Investigation Of The Hdl Molecular Architecture Before And After Exercise Training., Prasun Kumar Dev

Theses and Dissertations

The functional characteristics of high-density lipoprotein (HDL) particles are influenced by their structure, including their molecular composition (e.g. HDL lipidome and proteome).

Hallucinations In Large Foundation Models: Characterization, Quantification, Detection, Avoidance, And Mitigation, Vipula Rawte

Theses and Dissertations

Deception is an inherent aspect of social interactions, with research indicating that most people engage in deceptive behavior at least once or twice daily . In parallel, advances in artificial intelligence have led to machines exhibiting deceptive tendencies. These deceptions can be categorized into two types: unintended and intentional. Unintended deceptions - often referred to as hallucinations - occur when generative AI systems produce plausible and convincing narratives yet are factually inaccurate. This phenomenon primarily results from the systems' architectural design, extensive parametric memory, and reliance on statistical assumptions. In this thesis, we provide a comprehensive discussion on the characterization, …

Translating Theory Into Practice: Mediating Academic Advising Reform At Scale Through Improvement Science, Joshua Black

Theses and Dissertations

Improving student outcomes at community colleges is a difficult, multifaceted problem. While no single approach can be a panacea for such a challenging problem of practice, Guided Pathways (GP) research suggests a scalable reform model that may ultimately help to improve the underlying systems and structures colleges have designed to support their students, and in turn, may help colleges to achieve the goal of improved student outcomes more consistently. Because of the breadth of the GP model’s recommendations for reform, however, implementation is complex. To be effective, each of the reforms must be localized, adopted, and brought to scale within …

Frequency-Based Rapid Structural Damage Detection Using Embedded Edge Computing On Resource-Constrained Devices, Ryan Yount

Toward A Unified Conceptualization Of Social Capital, Paulina Erices-Ocampo, Miranda J. Lubbers, Jimi Adams

Faculty Publications

Social capital is among the most broadly used concepts in social science. Despite its shared understanding as beneficial resources available from the connections between people, authors vary widely in their conceptualizations of social capital. To extract clarity from these disparate perspectives, we offer a systematic framework for conceptualizing social capital, which identifies three primary theoretical dimensions of scholars’ conceptualizations of social capital: (a) where beneficial resources reside, ranging from within individuals to the relationships between individuals; (b) beneficial network structure, differentiating closure from brokerage arrangements; and (c) the level to which rewards accrue, distinguishing individual from collective benefits. We illustrate …

Time-Dependent Shear Flows And Their Applications In Parabolic–Parabolic Patlak–Keller–Segel Systems*, Siming He

Faculty Publications

In this study, we investigate the behavior of three-dimensional parabolic–parabolic Patlak–Keller–Segel systems in the presence of ambient shear flows. Our findings demonstrate that when the total mass of the cell density is below a specific threshold, the solution remains globally regular as long as the flow is sufficiently strong. The primary difficulty in our analysis stems from the fast creation of chemical gradients due to strong shear advection.

Nucleoredoxin Regulates Wnt Signaling During Pituitary Stem Cell Differentiation, Michelle L. Brinkmeier, Leonard Y M Cheung, Sean P. O'Connell, Diana K. Gutierrez, Eve C. Rhoads, Sally A. Camper, Shannon W. Davis

Faculty Publications

Nucleoredoxin (Nxn) encodes a multi-functional enzyme with oxidoreductase activity that regulates many different signaling pathways and cellular processes in a redox-dependent manner. Rare NXN mutations are reported in individuals with recessive Robinow syndrome, which involves mesomelic skeletal dysplasia, short stature, craniofacial dysmorphisms, and incompletely penetrant heart and palate defects. Here we report that Nxn is expressed in the ventral diencephalon and developing pituitary gland, and that Nxn deficient mice have pituitary dysmorphology and craniofacial abnormalities that include defects in the skull base and cleft palate. Nxn mutant mice exhibit reduced WNT signaling and reduced differentiation of pituitary stem …

Learning Lessons From Hard Truths: School Shootings, Devin Watson

South Carolina Association for Middle Level Education Journal

The American school system is plagued by violent attacks such as school shootings. Unfortunately, these events are incredibly difficult to predict. The security used for these schools is often found lacking and students aren’t getting the help needed. Part of the issue is the internal struggle of students in tough situations and teachers not being trained properly to help them. School security is more than just something at the gate. It’s about creating a safe environment that students can find sanctuary in. The solution is to provide better training for teachers and updating the physical security of the school.
