The Relationship Of Acculturation And Acculturative Stress In Latina/O Youths’ Psychosocial Functioning, Marsha Tafoya

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to better understand how acculturation and acculturative stress are related to self-esteem, depression, substance use, and substance use problems in 206 Latina/o youth. Acculturation is the social and psychological process of change that occurs when an individual or group comes in contact with a different culture. The acculturation process can be positive, improving one’s life chances in the new culture, or it could be negative due to the challenging nature of change and adaptation to new cultural and social expectations. This difficulty creates a type of stress, called acculturative stress that has been found to be …

Master's Theses

Salivary cortisol levels were taken on a male and a female howler monkey and compared with behavioral observations during their introduction to one another into an exhibit at the Hattiesburg Zoo in order to determine the link between behavior and stress. This study sought to answer the following research questions: What behavioral responses occur when two howler monkeys are introduced into the same exhibit at a zoo? How stressed are the animals at different stages of the introduction? And, what is the correlation between behaviors and hormones, if any?

The study spanned four phases including a baseline phase, the initial …

Long Term Effects Of Chronic Variable Stress Administered During Different Developmental Stages In Mice, Henry Boeh

Dissertations (1934 -)

A number of studies have suggested that the occurrence of past trauma can increase an individual's chance of developing PTSD from a new traumatic experience later in life. Trauma that occurs during childhood appears to have a particularly strong effect on this risk increase. Furthermore, conditioned fear responses have been shown to incubate over extended periods of time in animal models. To further investigate the role these phenomena play in the development of PTSD, this study exposed juvenile and adult mice to 7 days of chronic variable stress (CVS). One month later, a Pavlovian delay fear conditioning procedure was used …

The Mechanism Of Neuroprotection Mediated By Nicotinamide Mononucleotide Adenylyl Transferase (Nmnat), Yousuf O. Ali

Open Access Dissertations

Neurons need to be maintained to persist throughout adulthood for proper brain function. However neuronal activity, injury and aging exert physical stress on the nervous system, which compromise nervous system function. Healthy neurons are able to maintain their integrity throughout the lifespan of the animal, suggesting the existence of a maintenance mechanism that allows neurons to sustain or even repair damage. A forward genetic screening in Drosophila identified mutations in a gene called nmnat that cause a rapid and severe neurodegeneration immediately post neuronal differentiation and development. NMNAT protein was required to maintain neuronal integrity in an activity-dependent manner. When …

Stress And Status : How Socioeconomic Status Affects Stress In Young Adult Women, Emma Katharine Yovanoff

Theses, Dissertations, and Projects

Numerous studies highlight the connection between women with low socioeconomic status (SES) and stress; however, there is a gap in the literature in regards to women with high SES status or what these two groups may have in common. The present study used a mixed methods approach to examine how types and levels of stress differ between women ages 18-24 years who have lower and higher socioeconomic status. Participants were 106 women with either low or high SES between the ages of 18-24 years. Data were collected using an anonymous online survey to determine each participant's SES and to identify …

Coping Resources, Coping Styles, Mastery, Social Support, And Depression In Male And Female College Students, Kristen J. Aycock

Counseling and Psychological Services Dissertations

Depression is one of the most commonly-diagnosed disorders in college counseling centers (Adams, Wharton, Quilter, & Hirsch, 2008), so effective diagnosis and treatment are paramount to providing adequate care to college students. Treatment direction may depend on gender, however. Not only do males and females experience depression at different rates (Kessler et al., 2003), but there also is some evidence that factors predict depression differently by gender (Tamres, Janicki, & Helgeson, 2002). Specifically, the literature suggests that the choice of coping strategies may be gender-related; that perceived control is higher in males, yet more important to females; that social connectedness …

Bovine Respiratory Disease: Understanding How Stress Modulates Immune And Growth Parameters When Cattle Are Challenged With Respiratory Pathogens (Viral And Bacterial), Shollie Falkenberg

Theses and Dissertations

Bovine respiratory disease (BRD) complex is a multiactorial disease syndrome that results from various individual contributions and interactions of pathogen, host, and environmental/management factors. Despite the efforts in research, prevention and treatment, BRD remains a leading cause of economic loss in the cattle industry. While advances in therapeutics and new vaccines have been developed over the past 20 – 25 years, the incidence of respiratory disease does not appear to be on the decline, rather it is appears to be increasing. While bacterial and viral pathogens, and various stressors associated with BRD have been characterized, there are no animal models …

Influence Of Environmental Conditions On Biofilm Formation Of Listeria Monocytogenes, Jing Li

All Theses

L. monocytogenes is a Gram-positive bacterium, ubiquitously distributed in the environment. It is the etiologic agent of listeriosis, a food-borne disease affecting humans and a variety of vertebrates. L. monocytogenes can form biofilm which is a multi-cellular layer of adherent bacteria surrounded by an extracellular polysaccharide matrix. Biofilm bacteria are extremely resistant to sanitizers and are difficult to be eradicated, therefore posing a big challenge to food processing industry and food service department.
In this work, we tested the biofilm formation in a number of L. monocytogenes serotypes under different environmental conditions, such as temperatures, pH and media (BHI, LB, …

Role Of Cortisol In Social And Memory Impairments In Individuals With Velocardiofacial Syndrome (Vcfs), Daniel Jacobson

Master's Theses and Doctoral Dissertations

Velocardiofacial Syndrome (VCFS) is a genetic disorder characterized by numerous physiological and psychological symptoms. Little is known regarding the neuropsychological and hormonal substrates and the social functioning in individuals with VCFS. There is some evidence to suggest that the stress hormone cortisol contributes to social, cognitive, and communication deficits in related populations (Corbett, Schupp, Levine, & Mendoza, 2009). This study investigated the role that cortisol has on the social and cognitive impairments observed in children with VCFS. To this end, 11 children with confirmed VCFS were assessed for baseline cortisol levels and received neuropsychological testing that assessed attention, memory, language, …

A meta-analysis examined the current literature on quantitative stress and the impact on team performance and effectiveness. Results from nine independent samples (N = 1,794) indicated that quantitative stress has a negative effect on team outcomes, ῤ = -.41. Second, a lab study sought to discover …

Dealing With Manhood : General Strain Theory, Masculinity, And The Engagement In Illicit Drug Trafficking., Sonita L. Arnold

Electronic Theses and Dissertations

This thesis integrates James Messerschmidt's Masculinity Theory (1997) with Robert Agnew's General Strain Theory (1992) to examine the relationship between failure to achieve ideal masculine standards, resultant psychological stressors, and the decision to engage in illicit drug activity. OLS and Binary Logistic Regression was performed on a sample of male college students (N = 851) to examine three hypotheses. Findings support the hypothesis that a positive relationship exists between failed masculinity and negative emotions. Partial support was found for the hypothesis that a positive relationship exists between negative emotions and drug trafficking. Partial support was also found for the hypothesis …

What Attracts Older Nurses To Organizations? Psychological Moderators Of The Impact Of Flexible Scheduling And Mentoring Opportunities, Sarah Dubose

All Theses

The current study investigated two psychological moderators (generativity and occupational stress) of the impact of flexible scheduling and mentoring opportunities on the attraction and application intentions of older nurses of bridge employment age. Of the 600 registered nurses who were contacted via postal mail, 101 responded. Participants were randomly assigned to one of six conditions in which a hypothetical job advertisement was manipulated with varying levels each of flexible scheduling (input vs no input into the schedule) and mentoring opportunities (formal, informal, and none). Input was found to have a main effect on organizational attraction, but main effects were not …

A Phenomenological Model For Dynamic Recrystallization, Jason Mark Simmons

Theses and Dissertations

The present study develops a phenomenological adaptation to an internal state variable (ISV) model that incorporates the influence of dynamic recrystallization (DRX) in a material’s evolving microstructure and flow stress response. During metal forming and joining processes that promote internal heat distributions and large strains, microstructural processes often occur that result in a transformation of the evolving microstructure away from the base distribution. In an effort to lower the stored energy accumulated in the material’s lattice and grain structure, the deformed material may undergo a type of dynamic recovery process, such as DRX. In this study, the ISV model’s flow …

Social Support And Health Outcomes In Adolescents Experiencing Homelessness And Poverty: A Test Of The Main Effect And Stress-Buffering Hypotheses, Danijela Zlatevski

Wayne State University Dissertations

The health benefit and stress-buffering effects of social support were examined. Homeless (N=250) and housed (N=148) adolescents were assessed in adolescence and again in early adulthood, providing longitudinal data to help understand how these social constructs may change and influence health. The study was designed to test Cohen and Wills (1985) main effect and stress-buffering hypotheses. Current findings provide some support for the main effect hypothesis and some more limited support for the stress-buffering effect of perceived social support on mental health. Specifically, a main effect was found at baseline for network social support on number of substance abuse symptoms. …

Gender Differences In The Processing Of Acute And Repeated Stress, Jaidee Zavala

Open Access Theses & Dissertations

Chronic stress is implicated in the pathogenesis of a variety of diseases, including affective, immune and cardiovascular disorders, which are differentially experienced by men and women. Corticotropin-releasing factor (CRF), arginine vasopressin (AVP), and glucocorticoid receptor (GR) are the major regulators of the stress response and are widely expressed in the paraventricular nucleus of the hypothalamus (PVH), where adaptive responses to stress are generated. Adult male and female rats were subjected to single (acute) or 14 consecutive daily (repeated) 30 min restraint sessions, or maintained as unstressed controls. Rats were perfused after their final restraint, and their brain tissues sectioned and …

Neuroendocrine Mechanisms Mediating Pheromonal Modulation Of Behavior In Terrestrial Salamanders, Corina Wack

Electronic Theses and Dissertations

Pheromones are chemosensory cues released by an individual to cause a behavioral or physiological change in a conspecific. These changes can range from increasing a female's receptivity to altering hormone secretions in the body. The red-legged salamander (Plethodon shermani) is an emerging non-mammalian model for understanding the evolution of chemical communication due to their well-characterized pheromones. Plethodontid salamanders secrete pheromones from their submandibular gland, called mental gland pheromones. Previous studies showed that mental gland pheromones increased receptivity in females during courtship and also increased corticosterone (CORT) concentrations in males. CORT is a metabolic hormone that mediates vertebrate stress responses. To …

Evaluating Lethal And Sub-Lethal Effects Of Catch-And-Release Angling In Florida's Central Gulf Coast Recreational Atlantic Tarpon (Megalops Atlanticus) Fishery, Kathryn Yvonne Guindon

USF Tampa Graduate Theses and Dissertations

Atlantic tarpon are sought after because of their fighting ability on various tackle and support a popular, lucrative and predominantly catch-and-release recreational fishery in Florida. They are not commercially harvested or consumed by the general public, therefore assessing effects of catch-and-release angling on tarpon survival is critical to a sustainable fishery. Tarpon caught on artificial breakaway jig and traditional live bait fishing charters in Boca Grande Pass (n=42) and trips from the recreational fishery of Tampa Bay (n=40) were tagged with ultrasonic transmitters and tracked up to 6 hours immediately following release to estimate post-release mortality. Of the 82 tagged …

Applications Of Raman Spectroscopy For Silicon Stress Characterization In Integrated Circuits, Colin Mcdonough

Legacy Theses & Dissertations (2009 - 2024)

The introduction of mechanical stress in Si-based integrated circuits (ICs), whether desired or undesired, is intrinsic to IC fabrication. The origins are diverse and result from the numerous materials, geometries, and processes involved in fabrication. These stresses can lead to such effects as delamination, void formation and migration, and fracture, and can significantly affect device performance. As a result, stress development is a major concern for reliability, process control, and device design. It is necessary to investigate and characterize the origins and levels of the induced stresses. A more complete fundamental understanding of the evolution of stress in ICs and …
