Stakeholder Perceptions Of Microplastics Management In Oregon, Maya Hurst-Mayr

Environmental Science and Management Professional Master's Project Reports

There is currently no federal policy in the United States that specifically addresses microplastics (MPs) pollution. However, states are beginning to act on this issue; California's SB 1422 initiates measurement of MPs in drinking water resources and Senate Bill 1263 requires the state to adopt a strategy to reduce the ecological impact of MPs in marine ecosystems. Other West Coast states like Oregon and Washington are expected to follow California's example. It is important to know what the actors who are a part of shaping MPs policy in Oregon would see as barriers and opportunities to doing so. We conducted …

Voter Suppression Undermines Public Health For All, Erin Grinshteyn, Laura Chyu, Roman Pabayo

Journal of Interdisciplinary Perspectives and Scholarship

In the US, policies have actively suppressed the voices of Black, Indigenous, and people of color (BIPOC) while amplifying their oppressors’ voices. In spite of multiple constitutional amendments to guarantee access to the right to vote for those who initially were deprived of this right, attacks on this civil liberty have persisted. While some states have expanded access to voting rights in the past year, many others have made voting more difficult and some states have had a mixed approach of making voting easier in some ways and harder in others. This continued interest in creating systems in which it …

Does The Contraction History Of The Muscle Dictate Changes In Strength Following Resistance Training?, Zachary William Bell

Electronic Theses and Dissertations

Within-subject training models, whereby researchers apply an exercise condition to one limb, and a separate exercise condition to the opposing limb, have become routine amongst the exercise literature. However, no study has directly tested whether exercising one limb with a high-load condition will influence strength adaptations within the opposing limb, even when the opposite limb is training. Furthermore, muscle post-activation performance enhancement (PAPE) is representing local level changes, however, more research is warranted to understand if this can be differentially impacted with different types (e.g. low load vs. high load) of resistance training. The purpose of this study was to …

"How It Was Made", Bethany Fitts

Electronic Theses and Dissertations

This is a meta-autoethnography describing the researcher’s unfocused, rhizomatic research process throughout the COVID19 pandemic. Themes explored are the COVID19 pandemic, family, death, climate change, queer love, represenation, academia, genre, and religion. The study shows how multiple scales of grief arise during the research process. I locate this method within postcolonial theory of autoethnography that seeks to diversify structures within the academic genre.

Memoria, Historia Y El Feminismo Decolonial: Un Análisis De La Poesía De Cristina Rodríguez Cabral Y Otras Poetas Afrolatinas, Margaree Gabrielle Obioha

Electronic Theses and Dissertations

This study explores the poetic works of Afro-Uruguayan poet Cristina Rodríguez Cabral and other Afro-Uruguayan and Afro-Latina poets and identifies how their works contribute to the body of decolonized feminist literature. The investigation includes the historical context of Black women and Black women poets in Uruguay to set the stage for analyzing the main themes of Rodríguez Cabral’s poetry which include questioning the presentation of Afro-Uruguayan women from a European perspective, the construction of a firm and resilient Afro-Uruguayan woman and the embracing of sisterhood within the African Diaspora. These themes are strongly connected to decolonized feminism in that they …

Electrochemistry, Spectroscopy, And Mass Transport Of Lanthanide Solutes In Bis(Trifluoromethylsulfonyl)Amide-Based Ionic Liquids, Heather Danielle Hamilton

Electronic Theses and Dissertations

In this work, the characterization of lanthanide elements (Dy, Er, Gd, Ho, Tb, Tm, Yb) in various RTIL solvents based on the ubiquitous bis(trifluoromethylsulfonyl)amide anion (Tf2N-) was investigated. The effect of cation structure on the mass transport and electron transfer properties of Yb3+ in [X]-Tf2N RTILs is considered, where [X] is one of six quaternary ammonium cations with varying structure and chemical properties. Cyclic staircase voltammetry (CSV), rotating disk electrode voltammetry (RDEV), and electrochemical impedance spectroscopy (EIS) experiments are used for this purpose. For each RTIL, the dependence of the redox reaction is examined at each of the working electrodes: …

Presumed Unfit: The Dual Bind Faced By Pregnant And Parenting Youth In Foster Care, Kara R. Finck

American University Law Review

Pregnant and parenting youth in foster care are subject to a range of laws, policies, and practices that expose the realities of a child welfare system structured to focus on surveillance instead of support and family regulation instead of family integrity. Informed by my experience representing foster youth who become parents, this Article considers how youth in care are presumed unfit to parent their children because of a history in foster care and their age. A youth’s status as pregnant or parenting is weaponized to subject them to additional scrutiny, threats, and a shifting burden to justify their fundamental right …

Natural Law And Universal Human Rights, David F. Forte

Law Faculty Articles and Essays

Abdullahi An-Na'im has set his life's quest on attempting to find a way that Muslim society can be attuned to the moral commands of the Universal Declaration of Human Rights, a Western creation. At present, the Shari'a and the Declaration are in obvious tension, if not conflict, in areas such as freedom of religion and the rights of women. An-Na'im finds that the Shari 'a is a creation of man derived in history from an interpretation of Islamic sources. Muslims today can legitimately develop their own interpretation relying on the root sources of Islam, but only so long as those …

The Role Of Glis3 In Zebrafish Endocrine Development And Regeneration, Tasha Swenney

Murray State Theses and Dissertations

Maintenance of proper blood glucose homeostasis is governed by the endocrine cells of the pancreas. Dysregulation of blood glucose is characteristic of the disease, diabetes mellitus. Relatively little is known about the molecular mechanisms that underlie diabetes. The genes associated with more common forms of diabetes remain more enigmatic and likely have less direct roles in blood glucose homeostasis such as glucose sensing, insulin secretion, and β cell maintenance. GLIS3, a transcription factor involved in pancreatic development as well as the transcriptional regulation of insulin has been identified as a risk locus for type 1 and type 2 diabetes …

Using Design Thinking As An Instrument For School Improvement And Innovation In Public Schools, Beth Emery Peterson

Murray State Theses and Dissertations

Design thinking, a creative problem-solving method in which the end user is an active member of the design team, has historically been used in business and industry, but school leaders are beginning to use the process in education settings. This multiple-case study examined the experiences of two public school leaders who used design thinking for continuous improvement initiatives or to spur innovation in their school or district. Through interviews, the school leaders shared their purposes, outcomes, challenges, and insights of using design thinking to address complex educational problems. Results indicate that design thinking is appropriate to use for continuous improvement …

Lending A Paw: Does The Presence Of A Dog Increase Donations Given To Homeless Individuals?, Katherine Link

Murray State Theses and Dissertations

Prosocial behavior can be defined as any behavior that results in the benefit of another individual (Coyne et al., 2018). This study sought to investigate potential influences on the prosocial behavior of donating to the homeless. With a rise in both homelessness and dog ownership, this project sought to investigate how the presence of a dog may impact both the willingness to donate and monetary amount donated to a homeless individual. Results indicated a significant three-way interaction between the sex of the homeless individual, the sex of the participant, and the presence of a dog. Overall, the presence of a …

Barriers To Mental Health Service Use And Preferred Treatment Format Among Racial And Ethnic Minorities, Jasmine Maxwell

Murray State Theses and Dissertations

One of the most pressing concerns in mental healthcare is the limited use of mental health services across the country. Research has indicated that individuals from racial/ethnic minority groups are significantly less likely to seek mental health services, which has led many to examine specific barriers to treatment-seeking. Given research that has suggested that barriers to treatment-seeking may be structural, attitudinal, or cultural in nature, this study aimed to gain a better understanding of the relationship between these barriers and willingness to seek psychological help. Another goal of the current study was to examine the role of online therapy in …

The participants in the study were thirteen high school students of which twelve students were seniors and one was a junior from high schools of four rural districts of Western Kentucky. A generic qualitative research …

The Effect Of Intellectual Disability On The Perception Of The Validity Of Confessions, Audree Carner

Murray State Theses and Dissertations

Research shows that false confessions are more likely to occur in certain vulnerable populations, one of those being individuals with intellectual disabilities. The aim of the current study was to gain insight into the current knowledge and attitudes the layperson has about the possibility of an individual with an intellectual disability falsely confessing. Data were collected from 180 participants and after exclusion criteria were implemented, 94 participants were included in the current sample. It was hypothesized that participants would more often rate suspects as guilty and be more confident in their verdict if the suspect did not have an intellectual …

The Impact Of Socioeconomic Status On The Development Of Stem Identity, Choice, And Persistence, Shawna Adams

Murray State Theses and Dissertations

Abstract

This mixed-methods study seeks to investigate the direct effect that socioeconomic status (SES) has on a student's identity, choice, and persistence in science, technology, engineering, and math (STEM). There is a diversity and wage gap among the STEM workforce, which is comprised largely of White males with higher salaries than their counterparts. Underrepresented minority groups (URMs) are more likely to come from low SES and typically have fewer educational resources. Identifying the relationship of SES across student groups can yield insights about how to address inequitable practices and increase STEM diversity. Quantitative data was collected via a STEM survey, …

Return Of Floodplain Connectivity And Concurrent Macroinvertebrate Community Response Following Wetland Restoration In Western Kentucky, Christiane M. Soldo Ms.

Murray State Theses and Dissertations

Wetlands improve the quality of our nation’s streams, rivers, and lakes, and they support a diverse assemblage of plant and animal species. The U.S. Department of Agriculture Natural Resources Conservation Service (USDA-NRCS) is responsible for administering the Wetland Reserve Program (WRP), a multi-billion-dollar effort to restore wetlands throughout the nation. Each year, WRP enrolls thousands of acres of private farmland into conservation easements with the goal of improving water quality and creating wildlife habitat. Hydrological modification structures, such as levee breaks, ditch plugs, or shallow water areas are constructed on easements to create wetlands by improving water retention and returning …

Habitat Use And Diel Movements Of Silver Carp Hypophthalmichthys Molitrix In Two Southeastern Reservoirs, Levi Umland

Murray State Theses and Dissertations

Bigheaded carp have spread rampantly throughout the Mississippi watershed and continue to spread by navigating through rivers, locks, and dams. The long-term effects these species will have on our ecosystems and natural resources is unknown. Their movements, behavior, and general seasonal patterns are well studied within rivers. However, their movements and behavior within reservoirs is poorly understood due to their initial numbers within reservoirs being lower than in rivers. To address this gap, I investigated the distribution and movement rates of Silver Carp within two reservoirs, Kentucky Reservoir and Barkley Reservoir, and possible correlative variables, including wind, temperature, residency, sex, …

Isocaloric Low Protein Diet In A Mouse Model For Vanishing White Matter Does Not Impact Isr Deregulation In Brain, But Reveals Isr Deregulation In Liver, Lisanne E. Wisse, Denise Visser, Timo J. Ter Braak, Abdellatif Bakkali, Eduard A. Struys, Christopher D. Morrison, Marjo S. Van Der Knaap, Truus E.M. Abbink

Division of Basic Science Faculty Publications

Objective: Vanishing white matter (VWM) is a genetic brain white matter disorder caused by mutations in eIF2B. eIF2B is central in the integrated stress response (ISR), during which its activity is inhibited by various cellular stresses. VWM is a chronic progressive disease with episodes of rapid neurological deterioration provoked by stresses. VWM patients and VWM mouse models show ISR deregulation in brain, correlating with chronic disease development. ISR inhibition ameliorates the chronic disease in VWM mice. The subacute deteriorations have not been modeled yet. We hypothesized that ISR activation could worsen disease progression in mice and model the episodic neurological …

Obesity: Understanding And Achieving A Healthy Weight, George A. Bray, Catherine M. Champagne

Population and Public Health Science Faculty Publications

Obesity is a chronic, relapsing, stigmatized disease process that is increasing in prevalence, affecting both adults and children. It is the result of a small positive energy imbalance from too much food or too little activity. These underlying causes are influenced by many environmental factors. The food we eat is more than “calories,” and focusing on calories alone may not be as productive as focusing on patterns of eating and the role of sugar and fat in the diet. Obesity increases the risk of many diseases and shortens life span, and weight loss provides benefits in reducing health risks and …

Obesity, Body Composition, And Sex Hormones: Implications For Cardiovascular Risk, Prachi Singh, Naima Covassin, Kara Marlatt, Kishore M. Gadde, Steven B. Heymsfield

Clinical Research Faculty Publications

Cardiovascular disease (CVD) continues to be the leading cause of death in adults, highlighting the need to develop novel strategies to mitigate cardiovascular risk. The advancing obesity epidemic is now threatening the gains in CVD risk reduction brought about by contemporary pharmaceu-tical and surgical interventions. There are sex differences in the development and outcomes of CVD; premenopausal women have significantly lower CVD risk than men of the same age, but women lose this advantage as they transition to menopause, an observation suggesting potential role of sex hormones in determining CVD risk. Clear differences in obesity and regional fat distribution among …

Turning The Tides: An Inoculation Theory And Theory Of Planned Behavior Approach To Developing Mental Health Help-Seeking Interventions For Gen Z, Sarah Ann Geegan

Theses and Dissertations--Communication

Extensive research, predating and during the COVID-19 pandemic, demonstrates the rising prevalence of anxiety and depression among Gen Z college students in the United States—findings which are accompanied by rising rates of suicide, the second leading cause of death among people aged 15-24. Although college campuses often offer mental health resources, the number of college students utilizing them is significantly less than the number of students reporting mental health challenges. A dearth of empirical evidence, focused on Gen Z specifically, exists as a basis for developing interventions to address this issue. This investigation addressed this gap through two component studies. …

A Content Analysis Of Reddit Comments Discussing Fibroadenoma Appraisal And Decision Making, Hayley Marie Kay Stahl

Theses and Dissertations--Communication

Though fibroadenomas are clinically benign in most cases, clinical research suggests that these lesions can cause diagnosis-related physical health complications and psychological distress. However, this research is limited and should be investigated further. Thus, this study aimed to explore how patients appraise their fibroadenoma diagnosis uncertainty. Additionally, this study sought to determine if a correlation existed between appraisal and decision making as well as identify the factors that influence the most common treatment decision: removal. Data was retrieved from Reddit discussions for a content analysis. These discussions were then qualitatively analyzed using codebooks associated with this study’s research questions. Findings …

Decitizenizing Asian Pacific American Women, Shoba Sivaprasad Wadhia, Margaret Hu

University of Colorado Law Review

The Page Act of 1875 excluded Asian women immigrants from entering the United States, presuming they were prostitutes. This presumption was tragically replicated in the 2021 Atlanta Massacre of six Asian and Asian American women, reinforcing the same harmful prejudices. This Article seeks to illuminate how the Atlanta Massacre is symbolic of larger forms of discrimination, including the harms of decitizenship. These harms include limited access to full citizenship rights due to legal barriers, restricted cultural and political power, and a lack of belonging. The Article concludes that these harms result from the structure of past and present immigration laws …

Liquid Biopsies To Occult Brain Metastasis, Asad Ur Rehman, Parvez Khan, Shailendra K. Maurya, Jawed A. Siddiqui, Juan A. Santamaria-Barria, Surinder K. Batra, Mohd W. Nasser

Journal Articles: Biochemistry & Molecular Biology

Brain metastasis (BrM) is a major problem associated with cancer-related mortality, and currently, no specific biomarkers are available in clinical settings for early detection. Liquid biopsy is widely accepted as a non-invasive method for diagnosing cancer and other diseases. We have reviewed the evidence that shows how the molecular alterations are involved in BrM, majorly from breast cancer (BC), lung cancer (LC), and melanoma, with an inception in how they can be employed for biomarker development. We discussed genetic and epigenetic changes that influence cancer cells to breach the blood-brain barrier (BBB) and help to establish metastatic lesions in the …

Modulation Of Arginase-2 Mrna Levels By Ω-3 Pufas And Aspirin In Asthmatic Human Lung Fibroblasts, Vamsee K Duggirala, Kyla Geary, Donald Hasenmayer, Farzaneh Daghigh

PCOM Scholarly Works

Airway remodeling (AR) increases disease severity, and morbidity of asthmatic patients by contributing to irreversible airflow obstruction and progressive declines in lung function. Arginase isoenzymes and the downstream enzymes ornithine decarboxylase (ODC) and ornithine aminotransferase (OAT) have been implicated in the hyperplastic and fibrotic changes of AR, respectively. Omega-3 polyunsaturated fatty acids (ω-3 PUFAs) and resolvin metabolites have anti-AR effects, but whether they are mediated through the arginase pathway is unclear. Our study intended to determine the effects of the ω-3 PUFAs eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), resolvin D1 (RvD1), TH1 cytokines, acetylsalicylic acid (ASA), cAMP, …

Using Adaptive Governance To Protect Oregon’S Water Resources, Lauren Butz

Lewis & Clark Law Review

Over 30 years ago, Oregon adopted the innovative In-Stream Water Rights Act, which introduced new regulatory tools and incentives for encouraging efficient water consumption, and paved the way for the emergence of water trusts. However, Oregon’s water resources are under increasing strain as the state faces the challenges of over-appropriation and climate change. New solutions are needed to augment the existing regulatory framework. This Comment draws on the principles of adaptive governance and ecological resilience to formulate possible legal solutions to help the state adapt to increasing demands for water, proposing that Oregon leverage corporate social responsibility to encourage investments …
