Equity In Focus : Investigating Gender Disparities In Glioblastoma Via Propensity Score Matching, Solomon Eshun

School of Mathematical & Statistical Sciences Faculty Publications

Gender disparities in health outcomes have garnered significant attention, prompting investigations into their underlying causes. Glioblastoma (GBM), a devastating and highly aggressive form of brain tumor, serves as a case for such inquiries. Despite the mounting evidence on gender disparities in GBM outcomes, investigations specific at the molecular level remain scarce and often limited by confounding biases in observational studies. In this study, I aimed to investigate the gender-related differences in GBM outcomes using propensity score matching (PSM) to control for potential confounding variables. The data used was accessed from the Cancer Genome Atlas (TCGA), encompassing factors such as gender, …

Deriving Spatially Explicit Direct And Indirect Interaction Networks From Animal Movement Data, Anni Yang, Mark Q. Wilber, Kezia R. Manlove, Ryan S. Miller, Raoul Boughton, James Beasley, Joseph Northrup, Kurt C. Vercauteren, George Wittemyer, Kim Pepin

United States Department of Agriculture Wildlife Services: Staff Publications

Quantifying spatiotemporally explicit interactions within animal populations facilitates the understanding of social structure and its relationship with ecological processes. Data from animal tracking technologies (Global Positioning Systems [“GPS”]) can circumvent longstanding challenges in the estimation of spatiotemporally explicit interactions, but the discrete nature and coarse temporal resolution of data mean that ephemeral interactions that occur between consecutive GPS locations go undetected. Here, we developed a method to quantify individual and spatial patterns of interaction using continuous-time movement models (CTMMs) fit to GPS tracking data. We first applied CTMMs to infer the full movement trajectories at an arbitrarily fine temporal scale …

High Winds And Melting Sea Ice Trigger Landward Movement In A Polar Bear Population Of Concern, Annie Kellner, Todd C. Atwood, David C. Douglas, Stewart W. Breck, Colorado State University - Fort Collins

United States Department of Agriculture Wildlife Services: Staff Publications

Some animal species are responding to climate change by altering the timing of events like mating and migration. Such behavioral plasticity can be adaptive, but it is not always. Polar bears (Ursus maritimus) from the southern Beaufort Sea subpopulation have mostly remained on ice year-round, but as the climate warms and summer sea ice declines, a growing proportion of the subpopulation is summering ashore. The triggers of this novel behavior are not well understood. Our study uses a parametric time-to-event model to test whether biological and/or time-varying environmental variables thought to influence polar bear movement and habitat selection …

Evaluation Of The Effect Of Hydrated Lime On The Scavenging Of Feral Swine (Sus Scrofa) Carcasses And Implications For Managing Carcass-Based Transmission Of African Swine Fever Virus, Courtney F. Bowden, James Grinolds, Gregory Franckowiak, Loma Mccallister, Joe M. Halseth, Matthew Cleland, Travis Guerrant, Michael J. Bodenchuk, Robert Miknis, Michael C. Marlow, Vienna R. Brown

United States Department of Agriculture Wildlife Services: Staff Publications

African swine fever (ASF) is a devastating hemorrhagic disease marked by extensive morbidity and mortality in infected swine. The recent global movement of African swine fever virus (ASFV) in domestic and wild swine (Sus scrofa) populations has initiated preparedness and response planning activities within many ASF-free countries. Within the US, feral swine are of utmost concern because they are susceptible to infection, are wide-spread, and are known to interact with domestic swine populations. African swine fever virus is particularly hardy and can remain viable in contaminated carcasses for weeks to months; therefore, carcass-based transmission plays an important role in the …

Disease Progression And Serological Assay Performance In Heritage Breed Pigs Following Brucella Suis Experimental Challenge As A Model For Naturally Infected Feral Swine, Vienna R. Brown, Ryan S. Miller, Courtney F. Bowden, Timothy J. Smyser, Nicholas A. Ledesma, Aim E. Hartwig, Paul Gordy, Aaron M. Anderson, Stephanie M. Porter, Kate Alexander, Zane Gouker, Tom Gidlewski, Richard A. Bowen, Angela M. Bosco-Lauth

Invasive feral swine (Sus scrofa) are one of the most important wildlife species for disease surveillance in the United States, serving as a reservoir for various diseases of concern for the health of humans and domestic animals. Brucella suis, the causative agent of swine brucellosis, is one such pathogen carried and transmitted by feral swine. Serology assays are the preferred field diagnostic for B. suis infection, as whole blood can be readily collected and antibodies are highly stable. However, serological assays frequently have lower sensitivity and specificity, and few studies have validated serological assays for B. suis in feral swine. …

Validation Of A Nutria (Myocastor Coypus) Environmental Dna Assay Highlights Considerations For Sampling Methodology, Anna M. Mangan, John A. Kronenberger, Ian H. Plummer

United States Department of Agriculture Wildlife Services: Staff Publications

Nutria (Myocastor coypus) is a semiaquatic rodent species that is invasive across multiple regions within the United States. Here, we evaluated a qPCR assay previously described for use in Japan for application across invasive populations in the United States. We also compared two environmental DNA sampling methodologies for this assay: field filtration of large volumes of water passed through filters versus direct sampling of small volumes of water. We validated assay specificity, generality, and sensitivity, compared assay performance between two independent laboratories, and successfully tested the assay in situ on a known wild population. The filtration method required …

Perturbations Highlight Importance Of Social History In Parakeet Rank Dynamics, Annemarie Van Der Marel, Xavier Francis, Claire L. O'Connell, Cesar O. Estien, Chelsea Carminito, Virginia Darby Moore, Nickolas Lormand, Bryan M. Kluever, Elizabeth A. Hobson

United States Department of Agriculture Wildlife Services: Staff Publications

Dominance hierarchies can provide many benefits to individuals, such as access to resources or mates, depending on their ranks. In some species, rank can emerge as a product of a group’s history of social interactions. However, it can be difficult to determine whether social history is critical to rank in observation-based studies. Here, we investigated rank dynamics in three captive groups of monk parakeets (Myiopsitta monachus). We used experimental social perturbations to test whether social history shapes rank emergence in these groups. Using targeted removals and reintroductions, we tested whether differently ranked individuals could re-take their ranks in hierarchies after …

Integrating The Theory Of Planned Behavior And Bonding Social Capital To Examine Chinese Women’S Tampon Use Intentions, Yin Yang, Young Kim

College of Communication Faculty Research and Publications

This study integrates the theory of planned behavior with a structural approach to examining social capital to investigate how bonding social capital affected Chinese women’s tampon use intentions. Bonding social capital was operationalized as network closure, which included two main dimensions: density and hierarchy. Results from an online survey (N = 766) showed that network density was positively associated with attitudes toward, social norms about, and perceived behavior control around tampon usage, while network hierarchy negatively predicted attitudes only. Moreover, the indirect effects of network density on tampon use intentions were mediated by descriptive norms and perceived behavior control. …

Whose Public Virtue? Exploring Freedom Of Information Efficacy And Support, A.Jay Wagner

College of Communication Faculty Research and Publications

Little is known about public perceptions of how FOI laws influence government operations or impact citizens’ daily lives. A large representative sample of U.S. adults was surveyed for support of FOI laws and perceptions of FOI efficacy. Findings showed advanced education and higher perceptions of general government efficacy to be strongly significant in predicting both support for FOI and greater FOI efficacy. Males and liberal respondents also demonstrated significance in predicting support for FOI and higher FOI efficacy, while Black race was a significant negative predictor in support for FOI and whether FOI improved government operations and accountability.

Reporting At The Border: Translation In Periodicals At The Texas-Tamaulipas Border During The 19th Century, Gabriel Gonzalez Nunez

Writing and Language Studies Faculty Publications

This paper addresses the historical relationship between journalism and translation. It approaches translation history by considering journalistic translation as found in newspapers published in the Lower Rio Grande Valley (the southernmost, easternmost stretch of the Mexico-US border) during the 19th century. Specifically, the paper will ask whether translation was a tool employed in journalistic activity in the region and, if so, what the role was of translation in such activity. It will review the presence of translation in available border periodicals from the 1840s to the end of the century. This review will show that regarding certain aspects, historical news …

Examining The Lived Experiences Of Families With Children With Developmental Disabilities Participating In Recreational Dance Programs, Isabella Seguin

Theses and Dissertations (Comprehensive)

Objective

Families with children with developmental disabilities (DDs) experience effects on family functioning and will often turn to physical activity (e.g., dance) to mitigate these effects. This research examines the lived experiences of families with children with DDs participating in recreational dance programs to understand the myriad of effects on all participants: children with DDs, families, and dance instructors.

Methods

In order to fully understand the lived experiences of participants, phenomenology was used as the theoretical orientation to guide this research. Each case (5 cases, N=19) consisted of a primary parent, a child with a developmental disability, sibling(s) (if applicable), …

Discerning Friend From Foe: Systematic Revision Of Cuscuta L. Section Indecorae Using A Combined Ecological, Morphometric, And Phylogenetic Approach., Corey Burt

Theses and Dissertations (Comprehensive)

The genus Cuscuta (Dodder; Convolvulaceae) are obligate parasitic plants. In one clade known as section Indecorae, there are species which are considered pests that pose significant threats to agricultural crop production, while other species are rare or known only from historical records. Section Indecorae contains three species: C. coryli, C. warneri, and C. indecora (the latter with three infraspecific taxa: var. indecora, var. longisepala, and var. attenuata). The systematics of section Indecorae are not currently resolved. Cuscuta indecora has a long and complicated taxonomic history with many infraspecific varieties described, and …

I Am Queer And Asian: The Crossroad Of Race And Lgbtqia+ Identity Among Queer Asian Canadian Youth And The Impacts Of The Covid-19 Pandemic, Kenny Chee

Theses and Dissertations (Comprehensive)

LGBTQIA+ Asian youth face unique challenges due to their intersecting identities. Utilizing Asian Critical Race Theory and the Integration Model of Stress and Trauma in LGBTQIA+ Asians, LGBTQIA+ Asian youth are likely to experience detrimental mental health outcomes due to the stigmatization within their Asian culture and racial discrimination from the LGBTQIA+ communities. Moreover, the COVID-19 pandemic exacerbated existing challenges because of the closure of community spaces and increased hate crimes against Asians. Nonetheless, research on the intersectional experiences of LGBTQIA+ Asians in Canada, especially in the context of the COVID-19 pandemic is sparse. Thus, to address this gap, I …

Transformations Towards Just Urban Sustainabilities: A Community Psychology Approach To Analyzing And Fostering Urban Changes, Bianca C. Dreyer

Theses and Dissertations (Comprehensive)

Cities are uniquely positioned to drive social change towards more just and sustainable futures. However, while discourses of ‘transformations towards sustainability’ have gained prominence, their focus on integrating equity and justice and tackling the root causes of current unsustainabilities is lacking. This document outlines a research endeavor aimed at analyzing and fostering urban sustainable transformations from a community psychology perspective. This research is based on the assertion that without radical change based in equity and justice considerations, transformative efforts fail. First, a theory of just urban sustainable transformations (JUST) is suggested that draws on urban transformations and just sustainabilities scholarship. …

Common Sense Or Sensibility: Vaccine Hesitancy, Parens Patriae, And The Common Good, George P. Smith Ii

Scholarly Articles

Contending with national emergencies that develop into transnational catastrophes gives rise inevitably to concerns raised by libertarians and utilitarians over the extent to which the government — state, local, and federal — can restrict or redirect personal conduct to contain, if not resolve, any existing emergency condition. Using its parens patriae powers to protect the common good — especially the communal benefits of health and safety — government must endeavor to establish health care policies, and here, mandate vaccinations to combat the COVID-19 pathogen, against the benefits that are accruing to the general public. The conclusion drawn from this Article …

Restricting Scientific Legitimacy In The Age Of Biotechnology?, George P. Smith Ii

Scholarly Articles

In the Age of Biotechnology, there is no more pressing question than whether a philosophy of science exists and translates into a notion that—with or without qualification—the sovereignty of science is central to the advancement of society and should be totally emancipated from concurrence or oversight by society at large. Far too many Americans choose neither to be “informed” nor to accept the responsibilities of citizenship to participate fully in a deliberative democracy—they have chosen instead to exercise their “right” to remain ignorant. Consequently, science reigns without restraint or even review. The scientific community has a coordinated responsibility to society, …

Short Circuiting The Administrative Judiciary: A Response To Linda Jellum, Marshall J. Breger

Scholarly Articles

Linda Jellum provides a powerful analysis of the status of the exhaustion process for the SEC administrative judiciary and more broadly of the entire administrative judiciary. Many of her arguments are telling and on point. I disagree with a number of her technical and statutory arguments, and even more so the consequences of her analysis for the administrative state as we know it.

Jellum's argument is that Congress did not intend to preclude district courts from hearing constitutional challenges to SEC adjudications because agency ALJs are not the right adjudicators to hear challenges to the constitutionality of their own operations.

Property And Moral Responsibilities: Some Reflections On Modern Catholic Social Theory, Lucia A. Silecchia

Scholarly Articles

Professor Eric Claeys’s forthcoming book, Natural Property Rights, offers a deep perspective on property rights principles. However, while the law tends to focus—as I believe it must—on property rights, rights are inextricably intertwined with duties or responsibilities. The natural rights framework for property is, as Claeys says, “good enough for government work.” It reflects a principled way for the government to allocate property rights and use the law to protect them.

However, it is necessary to look beyond what is desirable for government to protect through law. Other sources propose parameters for reasoned use of property with an emphasis on …

Creating A Trust Through Delegation, Raymond C. O'Brien

Scholarly Articles

Aging in America has precipitated increasing use of planning for incapacity devices, which include forms creating powers of attorneys ("POAs'). Simple forms may be found online, or they may become part of a sophisticated estate planning portfolio drafted by professionals. Resultingly, to support portability, enforceability, and protection against financial exploitation of vulnerable adults, the National Conference of Commissioners on Uniform State Laws approved the Uniform Power of Attorney Act in 2006 ("UPOAA "), which has been adopted by more than half of United States jurisdictions. One of the Act's provisions requires an express grant of authority contained within the principal's …

Private Caregiver Presumption For Elder Caregivers, Raymond C. O'Brien

Scholarly Articles

The percentage of older Americans increases each year, with a corresponding percentage increase of those considered the older old. Many older persons will develop chronic conditions, decreasing their ability to manage the activities of daily living and requiring many to move into assisted living facilities or group homes. When surveyed, a majority of people expressed that they wish to age in their own homes, and government programs are increasingly supportive of this option. This is a viable option for many if they have the assistance of private caregivers—who provide a vast array of support services—and essential person-to-person human contact during …

The 2022 Conference Of Religiously Affiliated Law Schools: Reflections On Faculty Vocation And Support, Lucia A. Silecchia

Scholarly Articles

In the United States, numerous law schools identify themselves as “religiously affiliated.” There are many opportunities and challenges that come with such affiliation. What “religiously affiliated” may mean for a law school’s faculty is a particularly critical aspect of this question. I was grateful to have been invited to reflect on what religious affiliation might mean for faculty hiring at the “Past, Present, and Future of Religiously Affiliated Law Schools” conference. What follows are reflections that consider not merely that question—important as it is—but also explore what happens after the hiring decision to make the vocation to teach at a …

The Bare Necessity Of Natural Law, Adam J. Macleod

Scholarly Articles

According to legend, someone asked literary giant Samuel Clemens, better known as Mark Twain, whether he believed in infant baptism. He replied that, not only did he believe in it, he’d seen it done. Hundreds of generations of lawyers and jurists, including many of the most influential legal scholars and judges in history, have believed in natural law for the same reason. And many still do.

Natural law and natural rights are not “nonsense on stilts,” as Jeremy Bentham famously dismissed them.1 Natural law reasoning is what lawyers and judges do every day. Today, many people tend to think of …

Opus As The Core Of Property, Adam J. Macleod

Scholarly Articles

No account of property law can achieve a comprehensive understanding without factoring in natural rights. Professor Eric Claeys's new book offers a significant contribution to contemporary property theory by setting out the most comprehensive and defensible theory of natural property rights to appear in a long time. Claeys describes the function of property as productive work. Intentional planning, purposeful effort, and creative ordering enable people to achieve lives of flourishing. And, as Claeys demonstrates in careful detail, the various norms and institutions of property law make possible those exercises of practical reason and the flourishing that results from them. Natural …

Pressure Induced By Roll-Down Foam-Earplugs On Earcanal, Ahmed Dalaq, Luiz Melo, Franck Sgard, Olivier Doutres, Éric Wagnac

Études primaires

Physical discomfort of earplug is a common complaint, so much so it jeopardizes the health and safety of workers, resulting in frequent noncompliance to proper wearing of earplugs. A pressing need thus arises to understand the underlying mechanics for the interaction of earplugs with earcanal walls. An idealized cylindrical geometry of earcanal is first treated with computational and analytical modeling to predict the pressure induced by roll-down cylindrical PVC foam earplugs. In order to predict representative pressure values and distribution, we estimated the hyperelastic properties of foam-based earplugs and characterized their behavior using a stent testing machine (J-Crimp^TM machine) …

Commonalities And Differences In Carotid Body Dysfunction In Hypertension And Heart Failure, Igor S. A. Felippe, Rodrigo Del Río, Harold D. Schultz, Benedito H. Machado, Julian F R Paton

Journal Articles: Cellular & Integrative Physiology

Carotid body pathophysiology is associated with many cardiovascular-respiratory-metabolic diseases. This pathophysiology reflects both hyper-sensitivity and hyper-tonicity. From both animal models and human patients, evidence indicates that amelioration of this pathophysiological signalling improves disease states such as a lowering of blood pressure in hypertension, a reduction of breathing disturbances with improved cardiac function in heart failure (HF) and a re-balancing of autonomic activity with lowered sympathetic discharge. Given this, we have reviewed the mechanisms of carotid body hyper-sensitivity and hyper-tonicity across disease models asking whether there is uniqueness related to specific disease states. Our analysis indicates some commonalities and some potential …

Indigenous Long-Term Supports And Services – Elders, Traditional Knowledge, And Tree Rings, Cole Allick

Theses and Dissertations

American Indian and Alaska Native (AI/AN) Elders are rapidly aging and are a growing segment of Indian Country. Elders are critical to knowledge dissemination and enable the resiliency of Indigenous peoples through their teachings, wisdom, and guidance. There is a dire need to better understand and prepare for this rapidly aging population given that reliable data is limited or simply nonexistent. This dissertation in practice utilizes a framework inspired by Indigenous teachings of the Medicine Wheel and from the social ecological model to address the literature gap regarding Elders and healthy aging. This framework was created with intention that each …

Remote Sensing Of Chlorophyll-A In Small And Medium Lakes In The Minnesota Northern Forest Ecoregion, Jacob Alan Moll

Theses and Dissertations

Algae blooms have become increasingly common in many bodies of water and are occurring in more and more new locations. Past methods have relied on in-situ sampling to determine Chl-a concentrations and can be time and cost intensive. With the use of NASA’s Harmonized Landsat imagery existing methods of index calculation can be implemented, with the added benefit of an increase in temporal resolution. This increase in temporal resolution allows for more detailed spatial and temporal analysis such as hot spot analysis. Harmonized Landsat imagery was proven sufficient in spatial and temporal resolution for detection of Chl-a in small and …
