An Empirical Analysis Of The Mmpi-3 Suicidal/Death Ideation Scale, Brittany Barnes Rhodes

Theses and Dissertations

Suicide is a significant concern in society and is one of the leading causes of death in the United States and around the world. Suicidality is particularly prevalent in outpatient psychological treatment centers, with some studies estimating a tenfold increase in prevalence in this setting compared to the population at large. Several measures have been developed to assess suicide risk potential based on symptom frequency and combinations of risk factors, and broadband personality measures have also incorporated suicidality scales into their tests. The current study was focused on assessing the effectiveness of the Suicidal/Death Ideation (SUI) scale on the third …

The Impact Of Race-Related Stress On The Minnesota Multiphasic Personality Inventory (Mmpi-3) Of An African American Community Sample, Cassandra Clayton

Theses and Dissertations

Black Americans have endured profound racial discrimination and systemic injustices rooted in the historical legacy of slavery in the United States. These injustices persist today, permeating various facets of life, such as social interactions, education, politics, legal systems, and employment opportunities. Previous research has explored the cultural ramifications of these experiences, which often lead to race-related stressors and negative impacts on the psychological well-being of Black Americans. However, the exploration of how discrimination and racial stressors impact personality test scores of African Americans, such as on the Minnesota Multiphasic Personality Inventory, 3^rd edition (MMPI-3), is limited. This study investigated …

Transcending The Malaise Of Psychology By Being For The Other: An Alternative View For Psychotherapy, Kylie Marie Burdge

Theses and Dissertations

While psychological practice continues to expand, the sobering decline of mental health identified by Hillman and Ventura (1993) is evidenced by increased rates of suicide (Weir, 2019; Hedegaard, 2021; Stone et al., 2018) and psychopathology (Blue Cross Blue Shield Association, 2018; Twenge et al., 2010). Charles Taylor identified, in the same time frame as the noted decline of mental health, a malaise of modernity (1991), that is, the loss of meaning and transcendence in the modern world. Throughout the history of psychology and Western thought and culture, increased rates of psychological distress certainly coincide with what I will refer to …

Automation, Improvement, And Sensitivity Analysis Of 3d Parameterized Maize Stalk Models, Joseph Steven Carter

Theses and Dissertations

Maize is the most grown crop in the world. Each year, 5% of maize is lost due to a phenomenon known as stalk lodging (breakage of the stalk below the ear). One of the most promising solutions to stalk lodging is to design stalks with superior geometry to increase stalk strength. Researchers have developed a 3D parameterized maize stalk model, but these models take a long time to structurally analyze and are missing important material properties. This thesis addressed these problems by developing an automated package for analyzing the 3D parameterized maize stalk model, and by measuring the longitudinal shear …

Mental Illness Amongst Incarcerated Individuals And Its Effect On Gaining Employment, Tionna S. Miller

Theses and Dissertations

More than half the correctional population has a mental health disorder (NIH, 2022). Having a mental health disorder can severely interfere in one’s transition back into the community, specifically surrounding their access to employment.

This gives effective infrastructure management, which not only relies on the identification of the important predictors and their effects on bridge conditions but also ranks them …

Understanding Patterns Of Hope And Sense Of Belonging From Mentoring Through Latent Class Analysis, Bailey Dow

Theses and Dissertations

Youth who have safe, stable, nurturing relationships (SSNRs) are more resilient to adverse childhood experiences and have better mental health. Compared to prior generations, today’s youth feel lonelier and more socially isolated than ever, and they crave the sense of belonging and hope that comes from meaningful social connections. Mentors can play a crucial role in bolstering these attributes. Mentors help youth in different ways, depending on the mentee's characteristics, preferences, or circumstances. Despite the well-known significance of natural mentoring relationships as a SSNR, researchers have paid little attention to how and why natural mentoring benefits vary among mentees. The …

The Role Of Spatial Attention In The Maintenance Of Visual Working Memory: Modulatory Effect By Task-Relevance Of Spatial Information And Evidence From Alpha Oscillations, Sori Kim

Theses and Dissertations

The close interplay between spatial attention and visual working memory is essential for optimizing our visual experiences. The following studies investigated this interaction, focusing on how spatial attention influences visual working memory processes. In Chapter 2 a dual-task paradigm was used to examine how the relevance of spatial information to the task modulated the effects of spatial attention. The findings showed that shifting spatial attention away from a potential memory target impaired its consolidation in working memory. In Chapter 3, the experiment aimed to amplify these effects to observe clearer facilitatory and inhibitory processes. However, the results only demonstrated that …

A Process Planning Software For Modeling Parameter Behavior In Automated Fiber Placement, Benjamin Jeffrey Francis

Theses and Dissertations

The manufacturing of large-scale, geometrically complex composite structures is often accomplished today using the Automated Fiber Placement (AFP) process. AFP utilizes a fiber placement end effector and a gantry or robotic kinematic system to lay up groups of composite tows, iteratively building the complete structure. The reduced width of each tow allows the deployment of AFP for builds with significant curvature, unlike other automated methods such as automated tape laying. Despite its proven track record and widespread use, the current AFP process contains inefficiencies and suffers from workflow bottlenecks that significantly increase cycle time, material wastage, and overall cost. A …

Effect Of Storage Time And Temperature On Aggregation Of Alzheimer's Disease Amyloid-Β Protein, Amy Veihdeffer

Theses and Dissertations

Amyloid-β protein (Aβ) is widely studied due to its key role in Alzheimer’s disease (AD) pathology. One characteristic of patients suffering from AD is the deposition of amyloid plaques comprised of Aβ aggregates, which are associated with synapse damage. Thus, studying Aβ aggregation and aggregation inhibition may provide pathological and therapeutic insights. Aggregation of Aβ is a nucleation dependent process that may be influenced by the presence of pre-formed Aβ aggregate seeds that can facilitate formation of protein aggregates. These seeds may appear during preparation or storage of monomer, posing impact on experiments that study the aggregation process and the …

Discovering Therapeutic Strategies In Colorectal Cancer Via Synthetic Lethal Genetic Screens On Patient-Derived Organoid Models, Sana Khalili

Information Exchange Through Social Networks Links To Adoption Of Child Feeding Practices In Nepal, Mohammad Masudur Rahman

Theses and Dissertations

While there have been notable decreases in child undernutrition (i.e., stunting) over the past few decades, it remains a major concern in Nepal, with 25% of children under the age of five experiencing chronic undernourishment. There is considerable scope for improving nutrition-related behaviors to address this ongoing issue. In Nepal, knowledge regarding appropriate child feeding practices is often inadequate, and thus additional sources of accurate information are required. Information through multiple sources (i.e., interpersonal communication, mass media, and mobile SMS) provides opportunity to reach households who inadequately practice childcare. Information improves knowledge and information exchange (i.e., receiving or sharing) usually …

Retrospective Of My Experience At The University Of South Carolina, Karl Dickey

Theses and Dissertations

Theatre is, by its very nature, a collaborative process. No show lives in true isolation. Even in its smallest version, it takes at least one to perform and one to listen. The theatre that is produced in the 21^st century is deeper and more complex a process than the finished and polished shows that are presented to the audience. Behind, underneath, and all around a single performer on a stage are hours of thoughtful contemplation and execution on the part of the director, designers, and fabricators. There is something to be learned and gained from every human interaction in …
