Prediction Of In-Plane Stiffnesses And Thermomechanical Stresses In Cylindrical Composite Cross-Sections, Bryson M. Chan

Master's Theses

Accurate mechanical analysis of composite structures is necessary for the prediction of laminate behavior. Cylindrical composite tubes are a mainstay in many structural applications. The fundamental design of circular composite cross-sections necessitates the development of a comprehensive composite lamination theory. A new analytical method is developed to characterize the behavior of thin-walled composite cylindrical tubes using a modified plate theory. A generated numerical solver can predict properties such as axial stiffness, bending stiffness, layer stresses, and layer strains in composite tubes subjected to combined mechanical loading and thermal effects. The model accounts for the curvature by transforming and translating the …

Associations Between Parenting Stress, Feeding Practices, And Child Eating Behaviors During The Covid-19 Pandemic, Maria G. Gonzalez

Master's Theses

The COVID-19 pandemic provides an important opportunity to understand how parenting stress during social crisis may predict child feeding practices and perceptions of child mealtime behaviors. The objective of the present study was to explore whether parents’ perceived increases in and overall levels of parenting stress during the pandemic were associated with controlling feeding practices and perceptions of child eating behaviors. Parents (n = 284) of 4–6-year-old children completed a cross-sectional online survey between March and April 2020. The survey assessed parents’ perceived change in parenting stress during the onset of the pandemic and levels of parenting stress during …

The Effects Of Prescribed Burning And Microhabitat Type On Ant (Formicidae) Functional Groups And A Survey Of Ants In The Dr. Howard Reynolds Nature Area (A Mixed Grass Prairie), Ashley N. Durr

Master's Theses

This project sought to understand how prescribed burning and microhabitat type impacts Kansas ant functional groups and also whether prescribed burning in different microhabitat types altered the burn’s impact on those functional groups. The Dr. Howard Reynolds Nature Trail, located in Hays, Kansas, was burned in the spring of 2019. The area consists of 2 distinct habitat types: a dry, mixed-grass dominated uphill area and a moist, densely vegetated downhill area. Pitfall trapping was conducted during the summers of the year prior to the burn (2018) and the year following the burn (2019). 15 pitfall traps were spread across each …

Fracture Analysis Of The Lower Oceanic Crust, Atlantis Bank, Southwest Indian Ridge, Trent Jackson

Master's Theses

Atlantis Bank (AB) is an oceanic core complex (OCC), formed at the slow-spreading (spreading rate/yr) Southwest Indian Ridge (SWIR)-Atlantis II transform junction. AB is a domal massif composed of lower crustal and upper mantle rocks exhumed along a normal-sense detachment shear zone/fault. OCCs are of high interest since oceanic crust comprises the majority of Earth’s crust and OCCs form up to 15% of the crust that is formed at slow-spreading ridges. Brittle deformation, such as faults and fractures provide pathways for fluids to interact with the crust, which increases heat and mass exchange between the crust and hydrosphere, and is …

Exploring The Relationship Between The Nemaha Uplift And The Mid-Continent Rift Using 3d Mapping Visual Analysis, Faris Abanumay

Master's Theses

The present study presents and explains the relationship between Nemaha uplift and Mid-continent rift (MCR), where the understanding of the faulting systems around the study region were extremely important with regard to finding the relationship. The Nemaha is located in Kansas State in the Central United States with a total area of about 719 square miles. It was formed around the pre- Mississippian era. The compression and rifting processes that led to formation of faults, volcanoes, ridges and oceanic plates controls the faulting in the Nemaha region. The MCR system is a major tectonic feature in North America that is …

Characterization Of Andrenocortical Tissue Morphology, Histology, And Steroid Synthesis Among Finetooth (Carcharhinus Isodon), Blacktip (Carcharhinus Limbatus), Atlantic Sharpnose (Rhizoprionodon Terraenovae), And Bonnethead (Sphyrna Tiburo) Sharks, Danielle Elizabeth Bailey

Master's Theses

Adrenocortical (interrenal) tissue is composed of steroidogenic cells that produce corticosteroids involved in the stress response and hydromineral balance. Previous research characterizing the elasmobranch interrenal suggests that the number of interrenal bodies that produce the single primary corticosteroid, 1a-hydroxycorticosterone (1a-OHB), varies among species. However, potential species-specific differences in the amount of interrenal tissue and major steroid products produced have been understudied. To address this critical gap in our understanding of elasmobranch biology, this study examined interrenal morphology, cell structure, steroidogenic enzyme distribution (3bHSD), and steroid production in four shark species: Finetooth Carcharhinus isodon, Blacktip Carcharhinus limbatus, Atlantic Sharpnose …

The Moderating Effects Of Stress On The Relationship Between Self-Control, And Desire For Control, On Impulsive Purchasing, Katelynn Reed

Master's Theses

The current study examined the effect of self-control and desire for control on impulsive purchasing with stress as a moderator. Self-control has been found to be lower in individuals who engage in impulsive purchasing (Baumeister, 2002b), whereas little to no research on the effect of desire for control on impulsive purchasing has been completed. Stress has been found to relate with self-control and desire for control (Galla & Wood 2015; Leotti, Iyengar, & Ochsner, 2003). This study hopes to fill the research gap by exploring if stress moderates self-control and desire for control’s effect on impulsive purchasing. Participants were recruited …

The Impact Of Chronic Stress On Childhood Obesity And The Protective Effects Of Parental Warmth, Laura M. L. Distel

Master's Theses

Mexican American children have the highest rates of obesity in the U.S. Mexican American children may experience chronic stress, which has been linked to child obesity. Hair cortisol accumulation has been implicated as a mechanism for this association. Highly sensitive parenting may buffer the harmful effects of chronic stress and hair cortisol on obesity. Thus, the aims of this project were to 1) identify the direct and indirect effects of chronic stress and hair cortisol on children's zBMI and 2) examine the protective effects of parental warmth. This study examined hair cortisol levels, zBMI and chronic stress of children ages …

Stress Ecology Of The Pacific Rattlesnakes (Crotalus Oreganus And Crotalus Helleri), Natalie Claunch

Master's Theses

Stress is a physiological state induced by disturbance or adverse environmental conditions and is modulated by the glucocorticoid hormone corticosterone (CORT) in reptiles. Stressors can have various impacts on vertebrate trait expression and may affect survival or reproduction. Little is known about the effects of chronically elevated CORT in free-ranging reptiles, or the effect of disturbance stress on venom composition in captive snakes.

In chapter 1, we investigated the effects of researcher induced disturbance on CORT levels and venom composition in a group of captive Northern Pacific rattlesnakes (Crotalus oreganus). Venom protein concentration and plasma CORT levels were …

Trust, Reciprocity, Fairness, And Mind Reading Under Stress, Charles Jia Yao Xie

Master's Theses

Some hypothesized that when stressed, females activate tend-and-befriend, a stress response that enhances social abilities. Yet, critics argued this stress response is not exclusive to females and others suggested that males and females have different stress responses associated with social skills. This study intended to address these criticisms by testing whether males exhibit prosocial responses to stress and if particular stress responses improved social skills. To do this, 70 healthy introductory psychology students from a large public university in northern California were recruited to participate. Using random assignment, half of these individuals were exposed to an acute stressor and another …

Finite element analysis was used to study different tibial stem geometry types, as well as a vast array of different geometric sizes. Both a peg and stem type geometry were analyzed and compared in order to determine what type geometry causes the least amount of stress shielding. A static loading condition with a dynamic loading factor of three was used for the system and the stress responses were analyzed at regions of interest …

Seasonal Variation In Corticosterone, Stress Responses, And Physiology In The Northern Cardinal Cardinalis Cardinalis, Benjamin Matthew Duckworth

Master's Theses

Seasonal regulation of the adrenocortical response (e.g., ‘stress response’) appears to be ubiquitous in mid- to high-latitude vertebrates. Northern Cardinals (Cardinalis cardinalis) are a Temperate dwelling passerine of Tropical-descent with a wide species range (tropics to Northern Temperate zones). This species encounters a wide variety of environmental conditions and strong seasonality, however corticosterone (CORT, the main adrenal stress hormone) has not been studied with regards to changes in seasonal levels. I initially analyzed samples from cardinals collected between 2007-2011 from the Lake Thoreau Environmental Research and Educational Center (Hattiesburg, Mississippi, USA). The data suggested seasonal differences of CORT, with higher …

Stressed Induced Changes In Karenia Brevis Ribosomal Rna, David Scott Jayroe

Master's Theses

Karenia brevis is a toxic marine dinoflagellate that causes harmful algal blooms (HABs), also known as red tides, in the Gulf of Mexico. These blooms are responsible for massive fish kills, shellfish bed contaminations, adverse human health effects, and vast economic loss. For these reasons, extensive research has gone into understanding the mechanisms and dynamics of bloom behavior by studying K. brevis in the field and in the lab. In order to understand higher order bloom behavior and dynamics it is imperative to understand K. brevis at the cellular level. In growing K. brevis in vitro under a variety of …

This research addresses the significant gap in literature related to stress among 9-1-1 call-takers and dispatchers. The relationship between perceived stress and work-life balance, fairness at work, support at home, and work control as well as physiological and psychological outcomes is examined. Survey responses were collected during the summer of 2012 from 89 police 9-1-1 call-takers and radio dispatchers of the San José Police Department Communications Division in San José, California. Using hierarchical multiple regression analysis, I found those who enjoy a balance between work and personal life experience less stress. Also, greater stress is associated with more psychological and …

An Insight To Psychological Health, Health Behaviors, And Bodyweight Among Correctional Employees, Christina Mignano

Master's Theses

Background: Correctional employees present a poor physical and mental health profile including high rates of overweight/obesity, poor health behaviors (diet, exercise, and sleep quality), high stress levels, and poor psychological health (e.g. high rates of depression, suicide, and divorce). Worse, correctional employees deny their stress and negative emotions as their occupational culture discourages expressing negative characteristics that would make one appear weak and deters seeking psychiatric help. Correctional employees are in need of effective health promotion efforts that address determinants of employee health with an all-inclusive view (mental/emotional/behavioral). Purpose: The purpose of this study was to assess if stress and/or …

Adapting The Job Demand/Control Model To A Team Level, Clark Calabrese

Master's Theses

A better understanding of sources of stress within a teamwork context might be gained by applying the Job Demands/Control Model of stress (Karasek and Theorell, 1990) to teams as the unit of analysis rather than only to individuals as it is conventionally done. Team performance is frequently treated as a shared team-level outcome; it seems reasonable to assume that shared team characteristics are likely to have effects on stress as well. In particular, teams are unique in their requirement for coordination between team members. Therefore, the present study proposes an adapted Team Job Demands/Control Model of team-level stress phenomena in …

Prediction Of Residual Stress And Distortion From Residual Stress In Heat Treated And Machined Aluminum Parts, Robert Michael Jones

Master's Theses

Parts machined from relatively large thickness cross sections can experience significant deformations from high residual stresses that develop in the part during the heat treatment used to form the aluminum alloy. Uphill quenching is a process that can create a part with low residual stress and stable dimensions when the process is controlled properly. The uphill quenching process involves a solution heat treat, quench, cool to liquid nitrogen, steam blast, and then age to final temper.

In this thesis two parts were modeled using ANSYS. The first part underwent the uphill quench process in the rough machined state. The second …

The Effects Of Coping, Self-Esteem, And Social Support On Stress And Wellbeing, Emily Meyerhoffer-Kubalik

Master's Theses

The present study aimed to add to the literature on the internal and external factors that may buffer the negative effects of stress. Specifically, the present study examined the effects of coping styles, self-esteem, and social support on both psychological wellbeing and stress. Participants (N = 198) were administered a measure of coping styles (COPE), self-esteem (Rosenberg's Self-Esteem Scale), social support (SSQ-R), psychological wellbeing (MHI), and stress (ICSRLE). Results showed problem-focused coping and emotion-focused coping were associated with better psychological wellbeing and lower stress. Avoidant coping was associated with lower psychological wellbeing and higher stress. Self-esteem was also related to …

Transient Small Wind Turbine Tower Structural Analysis With Coupled Rotor Dynamic Interaction, George R. Katsanis

Master's Theses

Structural dynamics is at the center of wind turbine tower design - excessive vibrations can be caused by a wide range of environmental and mechanical sources and can lead to reduced component life due to fatigue, noise, and impaired public perception of system integrity. Furthermore, periodic turbulent wind conditions can cause system resonance resulting in significantly increased structural loads. Structural vibration issues may become exacerbated in small wind applications where the analytical and experimental resources for system verification and optimization are scarce. This study combines several structural analysis techniques and packages them into a novel and integrated form that can …

Stress, Anxiety, And Somatic Symptoms: A Comparison Of Biomarkers In A Clinical Sample, David J. Finitsis

Master's Theses

Anxiety disorders are the most prevalent class of mental disorders, often characterized by a chronic course and comorbid psychopathology. The anxiety-stress literature utilizing cortisol as a biomarker of the hypothalamus pituitary adrenal (HPA) axis has been inconsistent. The establishment of salivary alpha-amylase (sAA) as a biomarker of sympathetic nervous system (SNS) activation allows researchers an opportunity to examine the stress response more fully. This study sought to explore relationships between trait anxiety and salivary stress biomarkers in an outpatient sample attending a specialized anxiety treatment center. Multiple regression and moderator analyses were conducted to examine associations between psychosocial and physiological …

The Interactive Effects Of Coping Strategies, Gender, And Stress In The Prediction Of Internalizing Symptoms In African American Youth: An Application Of The Specificity Model, Cynthia Pierre

Master's Theses

The current study utilized a specificity framework in the examination of interactions among coping strategies, stressor domains, and participant gender in the prediction of depressive and anxiety symptoms. Participants were 273 African American adolescents (6th - 8th; mean age = 12.9; 58% female). Participants completed measures of universal and culturally-relevant coping strategies in response to a stressor. Stressors were coded by raters across dichotomous domains: interpersonality (interpersonal vs. non-interpersonal), duration (acute vs. chronic), controllability (controllable vs. non-controllable), and sexuality (sexual vs. non-sexual). T-tests were conducted to examine differences in reported coping across stress domains. Inconsistent with predictions, mean differences of …

Experiences Of Coping With Injury In Division I Athletes From Low-To-Middle Socioeconomic Status Backgrounds, Matthew Philip Bejar

Master's Theses

Injuries inevitably occur in any sport at any level. The integrated sport injury model is one of the most extensive frameworks to address the psychological responses to athletic injury. While this model posits that socioeconomic status (SES) influences how an athlete cognitively, emotionally, and behaviorally responds to an injury, no research has substantiated this claim. Low SES individuals experience an exceptional amount of stress, which may complicate how they cope with a negative event. The coping strategies employed by an athlete can have major implications on rehabilitation adherence, recovery time, and psychosocial well-being. The purpose of this study was to …

Relationship Between Cognitive Functions And Hormones, Daniel C. Miao

Master's Theses

Stress has been implicated by recent research to significantly contribute towards many cognitive and physiological deficiencies. One of the most popular topics of study is the effect of stress on inhibition, the all-or-none decision about an action or inaction. However, only recently have scientists begun investigating neuroendocrine molecules that link stress and inhibitory processing. Participants included San José State University undergraduates (27 male, 63 female, 1 unstated) who were exposed to the Trier Social Stress Test, an established stress task, and who were assessed before and after stress exposure for cortisol levels. Participants were also given a pre- and post-test …

House Finches, Carpodacus Mexicanus: Hormones, Stress, And Song Control Regions, Katherine Olivia Ganster

Master's Theses

Song production in songbirds is controlled by parts of the brain known as the song control regions (SCRs). During spring, gonads increase in size, males sing to attract mates, and SCRs become larger. This neuroplasticity is controlled by the change in day length and increased plasma testosterone (T) levels. Plasma T can be reduced by stress through the production of corticosterone (CORT), through the production of beta-endorphin, or through direct effects on the testes via the nervous system. We determined the T, estradiol, and CORT hormonal profiles of wild House Finches by capturing and sampling blood from the finches every …
