Perceptions Of Stress: Employee Participation In A Yoga Class, Rosemarie Lee
Perceptions Of Stress: Employee Participation In A Yoga Class, Rosemarie Lee
Walden Dissertations and Doctoral Studies
Abstract
Employees experience workplace stress that can affect their health resulting in chronic diseases such as diabetes, stress, hypertension, and cardiovascular diseases. Stress also contributes to staff presentism, absenteeism, and high turnover rate. The employee wellness program (EWP) yoga class at a metropolitan teaching hospital has not been evaluated for its effectiveness in employee stress reduction and improvement in employee health. The practice focus question for this project explored employees' perception of the impact of a metropolitan teaching hospital's EWP yoga class on their stress reduction and health promotion activities. The theoretical framework for this project is Lazarus' transactional model …
Parental Characteristics And Parent-Child Relationship Quality In Families With Disabled Children, Tammy Young
Parental Characteristics And Parent-Child Relationship Quality In Families With Disabled Children, Tammy Young
Walden Dissertations and Doctoral Studies
Parenting can be very challenging, especially when raising a disabled child. Children with disabilities require more supports and are more likely to be abused. The parent-child relationship is an important factor in ensuring child welfare. Little research has focused on identifying the impact of parenting characteristics on raising a child with a disability. The purpose of this study was to examine whether parenting style, parenting competence, and parenting stress were predictors of parent-child relationship quality in parents of children with disabilities ages 3 to 12 years. This study was quantitative and used multiple linear regression to identify predictor variables of …
Domestic Violence And Demographic Variables As Predictors Of Resiliency Among Young Adults, Sylvanus O. Abraham
Domestic Violence And Demographic Variables As Predictors Of Resiliency Among Young Adults, Sylvanus O. Abraham
Walden Dissertations and Doctoral Studies
An increased understanding of resilience may determine how human psychological development can result in positive outcomes despite adversarial situations. However, current studies have not provided a relevant predictive model that can adequately predict resilience, particularly among young adults exposed to domestic violence. Based on Bronfenbrenner's ecological systems theory, the purpose of this quantitative noncomparative study was to examine whether domestic violence, age, gender, ethnicity, individual emotional and physical abilities, types of domestic violence exposure, and frequency of domestic violence exposure could adequately predict resilience among young adults. Quantitative data were collected from 118 young adults in the Midsouth region of …
Initiating Factors Affecting Information Systems Project Success, Jonathan Olubunmi Afolabi
Initiating Factors Affecting Information Systems Project Success, Jonathan Olubunmi Afolabi
Walden Dissertations and Doctoral Studies
Information systems (IS) projects are complex and costly, but only a 3rd of IS projects are successful; the Standish Group reported that 32% of IS projects were successful in 2012. Although investments in research have led to improvements in practice, there is a general perception that management failures are responsible for the low rate of IS project success. The effects of initiating factors on project outcome had not been sufficiently explored; few IS researchers have explored the initiation phase. The purpose of this grounded theory study was to explore project initiation factors, including relational, as well as decision-making aspects, and …
Awareness And Attitudes Of Young Nigerian Immigrants In The United States To Sickle Cell Screening And Premarital Genetic Testing, Timothy Atolagbe
Awareness And Attitudes Of Young Nigerian Immigrants In The United States To Sickle Cell Screening And Premarital Genetic Testing, Timothy Atolagbe
Walden Dissertations and Doctoral Studies
The carrier frequency for sickle cell anemia among Nigerians, who account for a high percentage of African immigrants in the United States, is high, according to the World Health Organization. Even though sickle cell disease contributes $2.4 billion annually to U.S. health care expenditures, ascertaining the number of affected individuals in the U.S. is difficult because sickle cell is not a reportable genetic disease. However, according to the Census Bureau, the number of African immigrants continues to grow at a steady pace among the foreign-born immigrant population in the U.S. There is a lack of research on the contribution of …
Head Start Parent Perspectives On Child Exposure To Secondhand Smoke At Home, Christiana Abani Bekie
Head Start Parent Perspectives On Child Exposure To Secondhand Smoke At Home, Christiana Abani Bekie
Walden Dissertations and Doctoral Studies
Children exposed to secondhand smoke (SHS) are at risk of developing ear infections, asthma, wheezing, bronchitis, as well as retarded lung growth. Indoor smoking is the main source of children's exposure to SHS. Despite a downward trend in smoking, children from low income families, especially African American and Hispanic children, continue to be exposed to SHS at a higher rate than their wealthier counterparts. This multiple case study explored the perceptions of 15 parents of 3- to 5-year-old children currently enrolled in Head Start regarding children's exposure to SHS. This study relied on the social ecological model, the theory of …
Rediscovery Of Self After Counseling For Female Survivors Of Intimate Partner Violence, Tiffany Crayton
Rediscovery Of Self After Counseling For Female Survivors Of Intimate Partner Violence, Tiffany Crayton
Walden Dissertations and Doctoral Studies
Researchers have indicated that survivors of intimate partner violence (IPV) have lost a sense of self while being with their abuser. But little or nothing has been published on the rediscovery of self after counseling among female survivors of IPV. The purpose of this phenomenological study which helped to guide the research question and the method of the study was to help bridge the gap in the professional counseling literature by exploring the rediscovery of self after counseling from the perspective of female survivors of IPV. The research question for this study examined the lived experiences of 7 women who …

Renovations Needed: The Fda's Floor/Ceiling Framework, Preemption, And The Opioid Epidemic, Michael R. Abrams
Renovations Needed: The Fda's Floor/Ceiling Framework, Preemption, And The Opioid Epidemic, Michael R. Abrams
Michigan Law Review
The FDA’s regulatory framework for pharmaceuticals uses a “floor/ceiling” model: administrative rules set a “floor” of minimum safety, while state tort liability sets a “ceiling” of maximum protection. This model emphasizes premarket scrutiny but largely relies on the state common law “ceiling” to police the postapproval drug market. As the Supreme Court increasingly holds state tort law preempted by federal administrative standards, the FDA’s framework becomes increasingly imbalanced. In the face of a historic prescription medication overdose crisis, the Opioid Epidemic, this imbalance allows the pharmaceutical industry to avoid internalizing the public health costs of their opioid products. This Note …
The Uneasy Case For Patent Law, Rachel E. Sachs
The Uneasy Case For Patent Law, Rachel E. Sachs
Michigan Law Review
A central tenet of patent law scholarship holds that if any scientific field truly needs patents to stimulate progress, it is pharmaceuticals. Patents are thought to be critical in encouraging pharmaceutical companies to develop and commercialize new therapies, due to the high costs of researching diseases, developing treatments, and bringing drugs through the complex, expensive approval process. Scholars and policymakers often point to patent law’s apparent success in the pharmaceutical industry to justify broader calls for more expansive patent rights.
This Article challenges this conventional wisdom about the centrality of patents to drug development by presenting a case study of …
Characterizing The Requirement Of The Cmi/Trr Compass-Like Complex During Drosophila Development, Timothy Nickels
Characterizing The Requirement Of The Cmi/Trr Compass-Like Complex During Drosophila Development, Timothy Nickels
Master's Theses
The MLR family of COMPASS-like complexes are histone methyltransferase complexes that are associated with the activation of gene enhancers. In D. melanogaster, Cara mitad (Cmi, also known as Lpt) and Trithorax related (Trr) are central subunits of a complex orthologous to mammalian Lysine methyltransferase 2 C and D (KMT2C and KMT2D, also known as MLL3 and MLL2/4) that catalyze H3K4 monomethylation. Previous studies have demonstrated that mutations in these genes are associated with cancer and developmental disorders, but the mechanisms by which these alterations contribute to disease states are unknown. The Cmi-containing COMPASS-like complex and orthologous vertebrate complexes have been …
Freshwater Reservoirs: Global Warming’S Best Kept Secret, Beau Baily
Freshwater Reservoirs: Global Warming’S Best Kept Secret, Beau Baily
Seattle Journal of Environmental Law
Fresh water reservoir construction involves the decomposition of plants that were previously able to absorb greenhouse gas and prevent its release into the atmosphere. With these plants no longer able to absorb greenhouse gas, it is released into the atmosphere, making freshwater reservoirs a source of global warming. Due to an increasing demand for clean energy, countries are planning and constructing dams at unprecedented rates. With dams come reservoirs. While hydroelectric energy is clean energy, the methods used to harness that clean energy create environmental problems that contribute to global warming. Ironically, this hydroelectric boom could do more harm than …
Racial Complexities Of Outdoor Spaces: An Analysis Of African American’S Lived Experiences In Outdoor Recreation, Matthew Charles Goodrid
Racial Complexities Of Outdoor Spaces: An Analysis Of African American’S Lived Experiences In Outdoor Recreation, Matthew Charles Goodrid
University of the Pacific Theses and Dissertations
This thesis examines the racial power imbalances that exists within the outdoor recreation industry. Despite participation rates being quantified, limited research explores the lived experiences and perspective of people of color. In this study, I explore the socio-historical development of outdoor recreational spaces, existing environmental habitus and African Americans lived experiences in outdoor recreation. To emphasize the voice of the participants, twelve African American millennials were interviewed. Questions in the interviews revolved around their perception of outdoor recreation and personal experiences while participating in outdoor recreation. Three overarching themes emerged from their stories, i) the typology of outdoor recreation, ii) …
Endocrine Responses To Repeated Adrenocorticotropic Hormone Administration In Free-Ranging Elephant, Molly Mccormley
Endocrine Responses To Repeated Adrenocorticotropic Hormone Administration In Free-Ranging Elephant, Molly Mccormley
University of the Pacific Theses and Dissertations
Understanding the physiological response of marine mammals to anthropogenic stressors can inform marine ecosystem conservation strategies. Stress stimulates release of glucocorticoid (GC) hormones, which increase energy substrate availability while suppressing energy-intensive processes. Exposure to repeated stressors can potentially affect an animal’s ability to respond to and recover from subsequent challenges. To assess the endocrine response of a marine mammal to repeated stressors, we administered adrenocorticotropic hormone (ACTH) to free-ranging juvenile northern elephant seals (Mirounga angustirostris; n=7) once daily for four days. ACTH administration induced significant, but transient (<24 h) elevation in circulating cortisol levels (p < 0.0001). These increases did not vary in magnitude between the first ACTH challenge on day 1 and the last challenge on day 4. In contrast, aldosterone levels remained elevated above baseline for at least 24 hours after each ACTH injection (p < 0.001), and responses were greater on day 4 than day 1 (p < 0.01). Total triiodothyronine (tT3) levels were decreased on day 4 relative to day 1 (p < 0.01), while reverse triiodothyronine (rT3) concentrations increased relative to baseline on days 1 and 4 (p < 0.001) in response to ACTH, indicating a suppression of thyroid hormone secretion. There was no effect of ACTH on the sex steroid dehydroepiandrosterone (DHEA). These results suggest that elephant seals are able to mount adrenal responses to multiple ACTH challenges. However, repeated stress results in facilitation of aldosterone secretion and suppression of tT3, which may impact osmoregulation and metabolism. We propose that aldosterone and tT3 are informative additional indicators of repeated stress in marine mammals.
Spatial And Temporal Dynamics Of Batesian Mimicry Between Adelpha Californica And Limenitis Lorquini, Louis Albert Prusa
Spatial And Temporal Dynamics Of Batesian Mimicry Between Adelpha Californica And Limenitis Lorquini, Louis Albert Prusa
University of the Pacific Theses and Dissertations
Conspicuous coloration is one of the main ways that animals communicate. The use of eye-catching color patterns to warn predators of an unprofitable trait is referred to as aposematism. Once predators learn to recognize the color pattern, a new signaling niche becomes available where other species can share the same signal. This mimicry niche can involve a “hide in plain sight” strategy by mimicking or parasitizing this signal, with mimics lacking the defense and associated costs that make them unprofitable. This is termed Batesian mimicry, and it decreases predation by taking advantage of the memory and learning of the predator …
Unknown And Cryptic Diversity In The Adelpha Serpa-Group, Cassidi Rush
Unknown And Cryptic Diversity In The Adelpha Serpa-Group, Cassidi Rush
University of the Pacific Theses and Dissertations
The tropics are host to incredible insect diversity. One of the most charismatic groups that exhibit this diversity are the butterflies. Despite the tropical butterfly fauna being heavily researched, there remains much hidden diversity in the form of undescribed life histories and cryptic species. This is especially true among the species rich Nymphalidae, the brush-footed butterflies. Species in the genus Adelpha are known to be “the most trying taxonomically of all nymphalids” DeVries (1987), and as such are fruitful ground for uncovering unknown diversity. About half of the species within Adelpha have undescribed life histories, while A. serpa stands out …

Rational Design Of Peptides Binding Towards Human Pd-L1 Using Knob-Socket Model, Xingchen Zha
University of the Pacific Theses and Dissertations
Programmed death-ligand 1 (PD-L1) is a type 1 transmembrane protein that has been reported to play a vital role in mediating suppressed immunity. The interaction between PD-L1 and PD-1 delivers a negative signal that reduces the proliferation of these T cells and induces apoptosis at the same time. Antibodies that can block the Programmed death-ligand 1 (PD-L1) on tumor cells have been shown to alleviate cancer-induced immunosuppression. While antibodies have a great potential in various therapeutic uses, many drawbacks such as the high cost of production, huge molecular size, and poor permeability impose restrictions on the extensive use of full-length …
The Effect Of An Orff-Based Curriculum On Social Emotional Competence Of Migrant Children In A Suburban Kindergarten In Shanghai, Yuanyang Yue
University of the Pacific Theses and Dissertations
The goal of this research set in a kindergarten in a suburban school in Shanghai, China, was to determine the effect of an Orff-based music curriculum on migrant children’s social emotional competencies.
The quasi-experimental design included students in two kindergarten classes, where one class of 28 students was randomly assigned to receive the treatment while the other class of 28 served as the control group. The intervention was a 16-session Orff music curriculum over a period of eight weeks, aimed at improving children’s social competence. Data were collected from the two classroom teachers who provided ratings of their students’ social …
Production Of Synthetic Spider Silk, Ryan Matthew Hekman
Production Of Synthetic Spider Silk, Ryan Matthew Hekman
University of the Pacific Theses and Dissertations
Spider silk is a material that both has impressive mechanical properties and is also environmentally friendly. Though there are limitless potential engineering applications for such materials, industrial production of spider silk has proven to be challenging. Farming silk from spiders, as is done with silkworms, is not a viable option for large-scale production of spider silk due to the venomous and predatory nature of spiders. Here, an attempt is made to express synthetic spider silk minifibroins heterologously in Escherichia coli, to purify the recombinant spidroins from cell lysate, and to spin them into artificial fibers through a biomimetic process. Silk …
Should I Stay Or Should I Go? Complex Environments Drive The Developmental Plasticity Of Flight Capacity And Flight-Related Tradeoffs, Jordan R. Glass
Should I Stay Or Should I Go? Complex Environments Drive The Developmental Plasticity Of Flight Capacity And Flight-Related Tradeoffs, Jordan R. Glass
University of the Pacific Theses and Dissertations
Animals must balance multiple, fitness-related traits in environments that are complex and characterized by co-varying factors, such as co-variation in temperature and food availability. Thus, experiments manipulating multiple environmental factors provide valuable insight into the role of the environment in shaping not only important traits (e.g., dispersal capacity or reproduction), but also trait-trait interactions (e.g., trade-offs between traits). We employed a multi-factorial design to manipulate variation in temperature (constant 28°C vs. 28±5°C daily cycle) and food availability (unlimited vs. intermittent access) throughout development in the sand field cricket, Gryllus firmus. We found that fitness-related, life-history traits and trait trade-offs can …
Lewis’S Woodpecker Nest Success And Habitat Selection In Cottonwood Floodplain Versus Burned Conifer Forests, William M. Blake
Lewis’S Woodpecker Nest Success And Habitat Selection In Cottonwood Floodplain Versus Burned Conifer Forests, William M. Blake
Graduate Student Theses, Dissertations, & Professional Papers
Breeding habitat selection influences reproductive outcomes. Habitat selection may be adaptive and benefit populations, but it can also be maladaptive with negative consequences for populations. Understanding habitat selection and its influence on reproductive success, especially in species of concern, is critical for effective management. Lewis’s Woodpecker (Melanerpes lewis) is a Species of Concern that has experienced national population declines. We studied its abundance and reproductive success in two commonly selected breeding forest types (i.e., cottonwood floodplain and mixed-conifer burned), and nest-site characteristics (nest availability, food availability, and vegetation attributes) that have the potential to yield strong differences in …
Exploring Research-Based Yoga Interventions Targeting Underserved Women And Sexual Trauma: A Descriptive Study, Shannon Steele
Exploring Research-Based Yoga Interventions Targeting Underserved Women And Sexual Trauma: A Descriptive Study, Shannon Steele
Graduate Student Theses, Dissertations, & Professional Papers
BACKGROUND
Racial/ethnic, minority women of low socioeconomic status are disproportionately affected by sexual assault and are more likely to develop PTSD. Women’s social, economic and environmental circumstance may contribute to this disadvantage. Yoga has shown to reduce symptoms of PTSD in underserved women. However, it is unknown whether yoga interventions for underserved women who have experienced sexual trauma in the research literature are theory-based and whether constructs are consistent across interventions. Furthermore, it is unknown whether existing trauma-based yoga training programs incorporate similar constructs found in yoga interventions for underserved women who have experienced sexual trauma.
METHODS
A descriptive research …
Variation Of Tool Mark Characteristics In Frozen Bone As It Relates To Dismemberment, Elena Hughes
Variation Of Tool Mark Characteristics In Frozen Bone As It Relates To Dismemberment, Elena Hughes
Graduate Student Theses, Dissertations, & Professional Papers
The act of dismembering a body leaves identifiable marks on the bone. These marks, whether they be from knives, saws, axes, or any other tool, can help provide law enforcement with information about the type of tool they should be looking for. While there has been considerable research done on the marks left by different types of weapons, a factor that has not been examined is the differences in tool marks based on the condition of the body at the time of dismemberment. This study will initiate this new avenue of research by analyzing the differences seen in tool mark …
Zoning And Complementary Incentives To Protect Farmland: A Case For Missoula County, Kaitlin Mccafferty
Zoning And Complementary Incentives To Protect Farmland: A Case For Missoula County, Kaitlin Mccafferty
Graduate Student Theses, Dissertations, & Professional Papers
Urban sprawl reflects an inefficient use of land that diminishes both rural landscapes and quality of life turning farms, ranches and open space into siloed suburban communities. This results in less walkable cities with more traffic and air pollution, among other negative consequences. Farmland constitutes a particularly important resource that often faces degradation or loss due to sprawl. Higher quality agricultural soils are particularly desirable for development because they are flat and well-drained. Farmland is also important for urban communities concerning food security, environmental health, and economic well being. As American cities continue to grow, farmland around urban areas has …

This thesis addresses current water quality management challenges in the transboundary Kootenai/y River Basin, and how these challenges are shaped by historical, economic, political, and social factors. The water quality of this basin, both in the United State and Canada, has been severely affected by coal mining that has occurred in British Columbia over the last hundred years and continues to be threatened by several proposed mining expansion projects. The goals of this research are to uncover the forces shaping water management and to determine the potential for interested and affected parties to participate in crafting water quality protection measures. …
Avian Community Responses To Bison Grazing In North American Intermountain Grasslands, Danielle A. Fagre
Avian Community Responses To Bison Grazing In North American Intermountain Grasslands, Danielle A. Fagre
Graduate Student Theses, Dissertations, & Professional Papers
Grassland and shrubland songbird species are a guild of conservation concern in North America. Many of these species have experienced severe population declines, due to habitat loss and land use change. This makes the conservation and management of remaining habitat of crucial importance for this guild. Grazing by large herbivores is an ecosystem process in grassland systems, and in North America, one of the major historic grazers was the Plains bison (Bison bison). Bison are considered ecosystem engineers, because they modify habitat to be more or less suitable for other species, such as grassland and shrubland songbirds. Bison …
Biotic Pulses, Bryotic Pulses And The Effects Of Mosses On Communities And Ecosystems, Mandy Lynn Slate
Biotic Pulses, Bryotic Pulses And The Effects Of Mosses On Communities And Ecosystems, Mandy Lynn Slate
Graduate Student Theses, Dissertations, & Professional Papers
Non-vascular mosses are known to be ecologically influential and structure communities through their physiological and physical attributes. My dissertation had two objectives. The first goal was to understand how fundamental differences in the physiology of mosses might drive much of their ecological impact. Mosses frequently and rapidly fluctuate between dehydration and rehydration. During these transitions, the cellular integrity of moss is compromised and intra-cellular contents (carbohydrates, amino acids, and ionic compounds) are released. Thus during wet-dry transition periods, mosses have the potential to release pulses of nutrients which may have important effects on other species. However, few studies have explored …
The Ethosophy Of The Grizzly Man: Timothy Treadwell's Three Ethologies, Blake L. Ginsburg
The Ethosophy Of The Grizzly Man: Timothy Treadwell's Three Ethologies, Blake L. Ginsburg
Graduate Student Theses, Dissertations, & Professional Papers
This paper explores the ethical appropriateness and significance of Timothy Treadwell’s life among the bears and foxes of Alaska’s Katmai National Park and Preserve. In an attempt to reveal the formative and transformative aspects of Treadwell’s project, I rely upon an ethological framework developed by Matthew Calarco that moves beyond the narrow conception of ethology as a scientific practice aimed at systematic and rigorous documentation of the quantifiable aspects of animal behavior. While many people might be hesitant to conceive of Treadwell’s project as an ethological one, I hope to illuminate the ways in which his life among bears and …
Policy Analysis: Alaska Salmon Hatcheries, Jessica Eller
Policy Analysis: Alaska Salmon Hatcheries, Jessica Eller
Graduate Student Theses, Dissertations, & Professional Papers
Using an adapted Ecological Risk Assessment (ERA) - Evaluation, this study analyzes policy regulating Alaska salmon hatcheries to evaluate its effectiveness at sustaining wild salmon runs.When Alaska became a state in 1959, its salmon industry was suffering from years of overfishing. Runs were at an all-time low, prompting constitutional drafters to mandate management of salmon via the sustained yield principle. The hatchery system that operates today and is responsible for a third of the commercial catch each year was put in place in the 1970s to help supplement depressed salmon runs. The effects of hatchery salmon on wild salmon populations …
