Finite Element Study On The Influence Of Bone-Implant Interface Condition On Femoral Fracture After Cementless Total Hip Replacement, Caleb Onuh Yenusah
Finite Element Study On The Influence Of Bone-Implant Interface Condition On Femoral Fracture After Cementless Total Hip Replacement, Caleb Onuh Yenusah
Theses and Dissertations
Finite element analysis was performed on an implanted femur, using loads of daily living activities, performed by total hip replacement patients. A probabilistic bone fatigue failure model was utilized to analysis the risk of post-operative femoral fracture in different patient groups, depending on bone fatigue strength for young and elderly patients, and activity levels for normal and active patients. Different bone-implant interface conditions were considered: after surgery, osseointegrated, fibrous tissue covering, and loose. For young patients, the probability of failure is less than 4% for all cases. While in elderly patients, high of 28.2% and 57.9% are reported for normal …

Theses and Dissertations
The purpose of this preference study is to identify the effects that the presence of a healing garden may have, on the perceived stress of African American women living in in low-income public housing. Literature states that women who live in public housing experience higher rates of malnutrition, fatigue, susceptibility to infection, and premature death (Adler et al., 1994; Whelch and Kneipp, 2005). Few of these studies address healing gardens as solutions. The explanation of behavior while visiting a healing garden in this study will help to identify particular aspects of gardens that are perceived as therapeutic. This research compared …
Emotion Regulation As A Moderator Between Coping And Perceived Stress With Middle School Students In Rural Areas, Jabari Markeon Sellers
Emotion Regulation As A Moderator Between Coping And Perceived Stress With Middle School Students In Rural Areas, Jabari Markeon Sellers
Theses and Dissertations
As students mature the types and frequency of stressors increase with age. Notably, middle school can be a stressful transition period that includes new peer relationships and hormonal changes, along with an increased probability of experiencing bullying and suicide ideation. Stress has been shown to have negative effects in psychological and physiological functioning among adolescents (Brietzke et al., 2012; De Young, Kenardy, & Cobham, 2011; Green et al., 2010). Effective coping skills can help to buffer these issues, giving adolescents a repertoire of tools to use. Along with that, proper emotional regulation has been shown decrease the negative effects of …

Research has shown that psychotherapy patients experience increased physiological responsivity to stress which might negatively impact their experience in psychotherapy and their overall progress and outcome. The purpose of the present study was to investigate the effect of a heart rate variability biofeedback intervention on the physiological stress responsiveness and the psychotherapy outcomes of participants in psychotherapy. Forty college students attending psychotherapy at their university counseling center were divided into an experimental group and a control group. The experimental group participated in a 6-week biofeedback intervention and we assessed their physiological stress reactivity before and after implementation of the intervention, …
The Effect Of Therapy Dogs On Children In A Learning Environment, Kimberly Ann Sheckler
The Effect Of Therapy Dogs On Children In A Learning Environment, Kimberly Ann Sheckler
Theses and Dissertations
Having a dog in school can seem exciting for many students, but can these furry companions actually help students attain higher levels of academic success? The benefits of therapy dogs in an educational setting can be seen in many research studies. Dogs in the classroom can be used to calm fears, relieve anxiety, and teach skills to students (Lessons Learned from Dogs in the Classroom, 1996). Even though there is much evidence of the positive benefits of therapy dogs in a school, many schools still choose not to have therapy dog programs. This thesis looks at the benefits of therapy …
The Relationship Between Mindfulness And Stress Among College Students, Elizabeth Marie Vonderheyde
The Relationship Between Mindfulness And Stress Among College Students, Elizabeth Marie Vonderheyde
Theses and Dissertations
College students who have high levels of stress have reported difficulties with functioning on a daily basis, whether it be high anxiety due to classes or an increase in unhealthy habits like smoking or overeating. Studies have shown that those who practice mindfulness every day learn how to live with accepting the stresses in their lives (Siegel & Allison, 2016). This study explored the relationship between mindfulness and stress in college students from a medium size public university in the northeast. Two self-report measures were used to collect data though an online survey. Data were subjected to descriptive and inferential …
Transcriptional Response To Stressors In Arabidopsis Thaliana, Aya Abd Elsalam Galal
Transcriptional Response To Stressors In Arabidopsis Thaliana, Aya Abd Elsalam Galal
Theses and Dissertations
Stress is defined as any external force that can trigger a defensive response from an organism. In plants, stress is something that has been shown to affect plant reproduction and productivity by activating a defensive response. It can be caused by various things including but not limited to biotic or abiotic conditions such as temperature, drought or salt stress. Exposure to stress leads to the production of various transcriptomes that are governed by signals released as a result of the exposed stress. Arabidopsis thaliana is characterized by its inability to tolerate any form of extreme stress and given its status …

Reward Preferences In Domestic Horses (Equus Caballus), Elizabeth E. Jaeger
Theses and Dissertations
The present study examined stress response in domestic horses (Equus caballus) to determine if horses show preference for either traditional or natural horsemanship training methods to test the hypothesis that natural horsemanship would induce less stress. Our results show that natural horsemanship rewards elicited lower stress response in horses.
A Psychometric Evaluation Of The Recovery Stress Questionnaire For Athletes (Restq-Sport), Stacy L. Gnacinski
A Psychometric Evaluation Of The Recovery Stress Questionnaire For Athletes (Restq-Sport), Stacy L. Gnacinski
Theses and Dissertations
The Recovery Stress Questionnaire for Athletes (RESTQ-Sport; Kallus & Kellmann, 2016) has been utilized in over one hundred research studies on overtraining in sport (Kallus & Kellmann, 2016). Despite recommendations from researchers to incorporate the RESTQ-Sport into existing practices for monitoring athletes’ responses to training load, gaps in the literature impede the translation of the measure from research to practice (Saw, Main, & Gastin, 2015a; Taylor, Chapman, Cronin, Newton, & Gill, 2012). To address gaps in the literature and enhance knowledge regarding the measurement nuances of the RESTQ-Sport, three systematic studies were completed in the current dissertation project. For all …
Effects Of Laughter On Self-Report And Psychophysiological Measures Of Stress, Alese M. Nelson
Effects Of Laughter On Self-Report And Psychophysiological Measures Of Stress, Alese M. Nelson
Theses and Dissertations
The purpose of this study was to investigate the relationship between laughter and stress reduction. Past research indicates that humor is related to stress reduction, but little is known about the specific role of laughter. It was hypothesized that laughter would have a similar effect. Stress was elicited through a mental arithmetic task, which was followed by a viewing of either a laughter-inducing video or a control (nature) video. Stress levels were assessed with both self-report and psychophysiological measures, including heart rate and respiration rate. Data was analyzed using one-within and one-between repeated measures ANOVAs. It was found that there …

Evaluating A Personal Stress Monitoring System, Sneha Gogineni
Theses and Dissertations
Now-a-days, Life is generally much more stressful than in the past. "Stress" is the word that we use when we feel that we are overloaded mentally in our thoughts and wonder whether we can really cope with those placed upon us. Sometimes, stress gets us going and they are good for us but at other times, it could be the cause to undermine both our mental and physical health. The way we respond to a challenge can be considered as a kind of stress. Part of our response to a challenge is physiological and affects our own physical state. When …
Preserving Optical Confinement In Pecvd Sio2 Waveguides By Control Of Thin-Film Stress, Steven Jay Hammon
Preserving Optical Confinement In Pecvd Sio2 Waveguides By Control Of Thin-Film Stress, Steven Jay Hammon
Theses and Dissertations
Researchers at Brigham Young University (BYU) have developed an optical biosensor that can quickly analyze a sample to detect any type of nucleic acid based organism, such as viruses or bacteria. The biosensor's reliability over time is compromised due to water absorbing into the SiO2 waveguides of the chip. It was hypothesized that keeping the thin-film stress of the waveguides close to zero would slow or stop water absorption from occurring. Completion of this thin-film study relied upon a new plasma enhanced chemical vapor deposition (PECVD) machine and a new 3-D optical profilometer, both of which were installed in …
An Integrated Behavioral Model Of Healthcare Utilization Among Transgender And Gender-Nonconforming Adults, Megan Elizabeth Sutter
An Integrated Behavioral Model Of Healthcare Utilization Among Transgender And Gender-Nonconforming Adults, Megan Elizabeth Sutter
Theses and Dissertations
Transgender and gender-nonconforming (TGNC) individuals in the United States experience significant marginalization due to stigma enacted at the structural, interpersonal, and individual levels. As a result, this population has reported increased behavioral and physical health needs, as well as unique barriers to healthcare. Moreover, TGNC individuals have reported greater experiences of childhood abuse compared to cisgender individuals. The cumulative experiences of stigma-related stressors and adverse childhood experiences put this population at risk for the development of mental and physical health problems, increasing need for health services. However, TGNC individuals have reported being denied medical care and postponing seeking care due …
Effects Of Cumulative Risk On Asthma Outcomes In Urban Children And Adolescents, Samantha A. Miadich
Effects Of Cumulative Risk On Asthma Outcomes In Urban Children And Adolescents, Samantha A. Miadich
Theses and Dissertations
Pediatric asthma disproportionately affects racial/ethnic minority children and children living in low-income, urban areas. Many families living in low-income, urban areas experience a number of stressors that can place children/adolescents at risk for worse asthma outcomes. This study examined the impact of a cumulative risk model of stressors (e.g., ED visits, quick-relief medication use, lung function, asthma control, QOL) in urban children (7-12 years) with persistent asthma. This study further aimed to examine both the original cumulative risk model and an adolescent-specific cumulative risk model as predictors of asthma outcomes in a sample of 60 adolescents (13-17 years). Asthma-related caregiver …
A Biobehavioral Approach To Examining Moral Distress In Critical Care Nurses, Marian Altman
A Biobehavioral Approach To Examining Moral Distress In Critical Care Nurses, Marian Altman
Theses and Dissertations
Moral distress is a complex and challenging problem that may cause negative biopsycohosical and professional outcomes for critical care nurses. The purpose of this work was to explore the relationship between the ethical climate of the work environment and moral distress as experienced by critical care nurses; and to explore relationships among mediators of stress (nurse characteristics e.g. education (BSN, nonBSN), years certified as a critical care nurse, and tolerance of ambiguity) and their relationship with perceived stress, moral distress, health status and salivary alpha amylase. A descriptive correlational cross-sectional design was used for this pilot study of 100 critical …
Three Measures Of Coping In Video Games (Civ-Iii): The Development, Construct Validation, And Profile Analysis Of The Civ-Iii, Chelsea M. Hughes
Three Measures Of Coping In Video Games (Civ-Iii): The Development, Construct Validation, And Profile Analysis Of The Civ-Iii, Chelsea M. Hughes
Theses and Dissertations
Video games provide a competitive, goal-oriented environment. They involve individuals who often seek intentionally to frustrate their opponents’ goals. The gaming community is made up of players who vary in their interpersonal style, learning histories, and skill levels. In this rich and dynamic environment, stress is a common experience. Given the prevalence of gameplay in the population and the frequency of gameplay among gamers, it is important to examine coping responses to stressors, particularly maladaptive ones. The present research entails three studies. In Study 1, I use exploratory factor analyses to develop three scales purported to measure maladaptive coping strategies …
Depressive Symptoms Among College Students: An Exploration Of Fundamental Cause Theory, Peter A. Carrico
Depressive Symptoms Among College Students: An Exploration Of Fundamental Cause Theory, Peter A. Carrico
Theses and Dissertations
Fundamental Cause Theory suggests that socioeconomic and demographic factors are causal to various illnesses, including depression. However, no known previously existing research has used Fundamental Cause Theory to create a model of depression among college students. To do this, the present study conducted a stepwise binomial logistic regression to examine how socioeconomic status and the sociodemographic variables of Gender, Race, and Sexual Orientation, and others predict depressive symptoms in a large sample of undergraduates when controlling for stressful life events and social support (N = 2,915). Results support the hypothesis that socioeconomic disparities in depressive symptoms are the result …

Best Practices For Managing Burnout In Attorneys, Ilona Salmons
Theses and Dissertations
Attorneys in the United States suffer from higher-than-average rates of depression, substance abuse, and suicidal ideation. Although these facts are widely accepted, at the time of the study, there was no consensus in the legal or research communities as to the cause of these alarming statistics. The combination of behavioral and psychological distress experienced by attorneys may suggest that burnout is a contributing factor. This study examined the relationship between workplace stressors and professional burnout. The literature review summarized recent and landmark studies in the field, as well as explored characteristics unique to the legal profession that were putting attorneys …
Acculturative Stress And Depression Among Latinos/As: Investigating The Role Of Neighborhood Context, Rebeca Castellanos
Acculturative Stress And Depression Among Latinos/As: Investigating The Role Of Neighborhood Context, Rebeca Castellanos
Theses and Dissertations
Latinos/as are the fastest growing demographic in the United States (U.S. Census Bureau, 2015). As they encounter U.S. society, Latino/as may experience acculturative stress (Berry, 1997). Empirical evidence suggests that Latinos/as in the U.S. report high rates of depression symptoms (Wassertheil-Smoller et al 2014). Acculturative stress has been strongly associated with depression (Driscoll & Torres, 2013) and research suggests that Latino/as may experience acculturative stress differently depending on their generational status (i.e., how recently they or their parents immigrated to the U.S). There is evidence to suggest that contextual factors such as neighborhood context may influence both acculturative stress processes …
