Spatial Analysis Of Bike-Sharing Station Usage And Placement: Redefining Bike-Share Planning For Equity, Sydney E. French

Graduate Theses, Dissertations, and Problem Reports (ETD)

Historically, bike share system (BSS) station locations have been guided by potential economic and environmental benefits associated with increased bike share usage per station. For example, a typical location identification approach may attempt to maximize demand per station based on population size or activity and area characteristics. Such identification methods often result in an unequal representation of specific population groups among the systems’ users, thus hindering the potential sustainability-related benefits. To address these disparities, some bike share organizations have started developing and implementing equity-oriented programs focusing on expanding their reach to underserved communities. Nevertheless, the effectiveness of such programs has …

What Gives? Leveraging Marketing Knowledge To Increase Consumers’ Charitable Giving, Caitlin Michael

Graduate Theses, Dissertations, and Problem Reports (ETD)

Marketing plays a central role in nonprofit organizations that compete for the donations of individual consumers to achieve their respective missions. To this end, marketing researchers and practitioners have devoted much attention to the antecedents of charitable giving and ways in which solicitations may be made more effective and efficient. This gives rise to the questions: “What has the field learned?” and, relatedly, “What novel effects have not yet been explored?” Within this dissertation, three essays address these questions through the use of multiple methodologies.

The first essay seeks to outline what the marketing field has learned about consumers’ charitable …

Spiking Neural Network That Maps From Generalized Coordinates To Cartesian Coordinates, Chloe K. Guie

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this thesis, I look to understand how insects compute task-level quantities by integrating range-fractionated sensory signals to create a sparse-spatial coding of Cartesian positions. I created biologically plausible 2-D and 3-D models of one species of the stick insect (Carausius morosus) leg and encoded the foot position through a spiking neural network. This model used spiking afferents from three angles of an insect leg which are integrated by one non-spiking interneuron. This model contains many dendritic compartments and one somatic compartment that encode the foot’s position relative to the body. The Functional Subnetwork Approach (FSA) was used …

Investigating The Interactions Of The Iron-Sulfur Mitochondrial Protein, Mitoneet With Its Binding Partners, Ebenezer Osei Newton

Graduate Theses, Dissertations, and Problem Reports (ETD)

MitoNEET belongs to the CDGSH Iron-Sulfur Domain (CISD)-gene family of proteins and is a [2Fe-2S] cluster-containing protein found on the outer membrane of mitochondria. The specific functions of mitoNEET/CISD1 remain to be fully elucidated, but the protein is involved in regulating mitochondrial bioenergetics in several metabolic diseases. Unfortunately, drug discovery efforts targeting mitoNEET to improve metabolic disorders are hampered by the lack of ligand-binding assays for this mitochondrial protein. We have developed a protocol amenable for high-throughput screening (HTS) assay, by modifying an ATP fluorescence polarization method to facilitate drug discovery targeting mitoNEET. Based on our observation that adenosine triphosphate …

Evaluation Of A Novel Mrna-Pertussis Vaccine Against Emerging Clinical Isolates Of Bordetella Pertussis, Graham Jeffrey Bitzer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Bordetella pertussis is a Gram-negative obligate aerobe that causes a respiratory disease known as pertussis or whooping cough. Pertussis is most severe in younger children, especially infants but the bacteria has been known to colonize adult populations. Before the introduction of the whole-cell pertussis (wP; wP-DTP) vaccine reported numbers of pertussis cases within the US routinely topped 100,000 cases per year. However, with the widespread usage of the wP vaccine case numbers began dropping and reached a low of less than 5,000 cases per year in the late 1970’s and early 80’s. It appeared that B. pertussis was heading towards …

Sinonasal Outcomes Using Oral Corticosteroids In Patients With Chronic Rhinosinusitis With Nasal Polyps And Positive Sinonasal Cultures, Jhon F. Martinez Paredes, Angela M. Donaldson, Michael Marino, Garret Choby, Osarenoma Olomu, Razan Alfakir, Janalee K. Stokken, Erin O'Brien, Devyani Lal

School of Medicine Publications

Introduction: Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and positive sinonasal bacterial cultures may be recalcitrant to topical therapy alone due to the additional local inflammatory burden associated with bacterial infection/colonization.

Objective: To evaluate sinonasal outcomes in CRSwNP patients with a positive perioperative bacterial culture, who were treated with postoperative intranasal corticosteroids (INCS) alone versus INCS in combination with a short-term course of oral corticosteroids (OCS).

Methods: This is a retrospective chart review of CRSwNP patients. A total of 59 patients met inclusion criteria, including positive perioperative bacterial culture and treatment with INCS with or without concomitant use of …

Well-Being, Changes To Academic Behavior, And Resilience Among Families Experiencing Parental Immigration Imprisonment, Caitlin Patler, Gabriela Gonzalez

Faculty Research, Scholarly, and Creative Activity

While the deleterious impacts of parental incarceration are well documented, we know less about the experiences of children with parents imprisoned by immigration authorities. We draw from 62 multigenerational and multiperspective interviews conducted in California with school-age children experiencing parental immigration imprisonment (PII), and their nondetained caregivers. We find that children experiencing PII report feelings and behaviors suggestive of significant psychological distress, which leads to changes in engagement and behavior at school. While some children access academic support and counseling, often following advocacy from nondetained parents or interventions by teachers, others do not receive such support. Many children conceal their …

Aortic Remodeling Kinetics In Response To Coarctation-Induced Mechanical Perturbations, Arash Ghorbannia, Mehdi Maadooliat, Ronald K. Woods, Said H. Audi, Brandon J. Tefft, Claudio Chiastra, El Sayed H. Ibrahim, John F. Ladisa Jr.

Biomedical Engineering Faculty Research and Publications

Background: Coarctation of the aorta (CoA; constriction of the proximal descending thoracic aorta) is among the most common congenital cardiovascular defects. Coarctation-induced mechanical perturbations trigger a cycle of mechano-transduction events leading to irreversible precursors of hypertension including arterial thickening, stiffening, and vasoactive dysfunction in proximal conduit arteries. This study sought to identify kinetics of the stress-mediated compensatory response leading to these alterations using a preclinical rabbit model of CoA.

Methods: A prior growth and remodeling (G&R) framework was reformulated and fit to empirical measurements from CoA rabbits classified into one control and nine CoA groups of various severities …

Security Of Text To Icon/Image Conversions, Zobaida Alssadi, Marius Silaghi

Electrical Engineering and Computer Science Faculty Publications

Using images and icons to represent news or narratives has grown in popularity. Still, one critical problem is that they are not equivalent to language, making them vulnerable to adversary attacks. This study examines the impact of image-poisoning attacks based on polysemantic words and of image attacks based on cultural differences when converting text to images. Such attacks can lead to the loss of important information and create confusion and incorrect interpretations of the intended meaning, misinforming the general public. The study specifically focuses on possible effects in a news and story context. This study highlights the significance of taking …

One Size Does Not Fit All: Alternatives To The Federal Rules Of Evidence, Henry Zhuhao Wang

Scholarly Publications

The Federal Rules of Evidence have been so successful that many people easily equate them to the whole field of evidence law. But this is a false equivalence. Our world is complicated, diversified, and dynamic. So too is evidence law, which is like a rainforest in which the Federal Rules are simply the largest tree, not a forest unto themselves. In fact, the Federal Rules of Evidence are limited in their applicability due to three fundamental assumptions: the presence of a jury trial, an adversarial process, and witness oral testimony.

This article illustrates the dominance of the Federal Rules of …

Racialization And International Security, Richard W. Maass

Political Science & Geography Faculty Publications

Racialization—the processes that infuse social and political phenomena with racial identities and implications—is an assertion of power, a claim of purportedly inherent differences that has saturated modern diplomacy, order, and violence. Despite the field's consistent interest in power, international security studies in the United States largely omitted racial dynamics from decades of debates about international conflict and cooperation, nuclear proliferation, power transitions, unipolarity, civil wars, terrorism, international order, grand strategy, and other subjects. A new framework lays conceptual bedrock, links relevant literatures to major research agendas in international security, cultivates interdisciplinary dialogues, and charts promising paths to consider how overt …

Hide And Seek: An Exploration Of Antipredator And Predator Avoidance Mechanisms In Orthopodomyia Signifera In Response To Predation From Toxorhynchites Rutilus, Nathaniel Dahlberg

Master's Theses

There have been many observations of larval Orthopodomyia signifera coexisting with the predator Toxorhynchites rutilus. There are three hypotheses that could explain how Or. signifera resists predation from Tx. rutilus. The first hypothesis states that larvae adapt behavioral changes that limit predation. The second hypothesis states thoracic setae serve as a physical defense that prevents Tx. rutilus from grasping Or. signifera. The third hypothesis states Or. signifera possess a chemical defense indicated by aposematic coloration. To test the first hypothesis larval Or. signifera were exposed to conspecific and heterospecific predation cues and their behavior was observed. Both cues …

Physical Therapy Faculty Research and Publications

Objective: Evaluate patellofemoral cartilage health, as assessed by quantitative magnetic resonance imaging (qMRI) T₂ relaxation times, 24-months after ACL reconstruction (ACLR) and determine if they were associated with patellofemoral contact forces and knee mechanics during gait 3 months after surgery.

Design: Thirty individuals completed motion analysis during overground walking at a self-selected speed 3 months after ACLR. An EMG-driven neuromusculoskeletal model was used to determine muscle forces, which were then used in a previously described model to estimate patellofemoral contact forces. Biomechanical variables of interest included peak patellofemoral contact force, peak knee flexion angle and moment, and walking speed. …

Covid-19 Vaccination And Alcohol Consumption: Justification Of Risks, Pavel A. Solopov

Bioelectrics Publications

Since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, pharmaceutical companies and research institutions have been actively working to develop vaccines, and the mass roll-out of vaccinations against COVID-19 began in January 2021. At the same time, during lockdowns, the consumption of alcoholic beverages increased. During the peak of vaccination, consumption remained at high levels around the world, despite the gradual relaxation of quarantine restrictions. Two of the popular queries on search engines were whether it is safe to drink alcohol after vaccination and whether this will affect the effectiveness of vaccines. Over the past two …

Aim: We tested the potential of cold atmospheric plasma (CAP) for the decontamination of flexible endoscope various surfaces, measuring total proteins and prion-residual infectivity as an indicator of efficacy.

Methods: New PTFE endoscope channels and metal test surfaces spiked with test soil or prion-infected tissues were treated using different CAP-generating prototypes. Surfaces were then examined for the presence of residues using very sensitive fluorescence epi-microscopy. Prion residual infectivity was determined using the …

Let’S Groove: A Dance Program Designed For Children With Disabilities, Michayla Burckhard

Occupational Therapy Capstones

Children with disabilities face limited opportunities to participate in the occupation of dance when compared to opportunities available for their non-disabled peers. Barriers to their participation include lack of class opportunities, cost, and knowledge about programs (Carrion et al., 2018). Many dance studios offer integrated or non-specialized classes, but participation by a child with a disability in this type of class is sometimes limited by parental or child fears, or other barriers such as lack of accommodations (Lucas, 2017).

A Holistic Approach To Promoting Sleep For People Emerging From Homelessness: A Good Night’S Rest In Your Nest Sleep Toolkit, Anna Frances Burggraf

Occupational Therapy Capstones

Sleep deprivation has been directly linked to chronic health issues, decreased physical and cognitive functioning, and overall decreased quality of life, which limits the ability to engage in desired tasks and occupations (Gonzalez & Tyminski, 2020). Individuals who have experienced homelessness consistently demonstrate higher rates of sleep inadequacies compared to the general public, which highlights the need for service providers to address the quality of sleep participation for this population (Gonzalez & Tyminski, 2020).

Exploring Nature-Based And Animal-Assisted Therapies As A Therapeutic Modality, Rachel Cheatley

Occupational Therapy Capstones

Animal-assisted therapy (AAT) is characterized by integrating animals into the therapy process as a therapeutic partner and modality (Laskowski et. al., 2019). AAT shows positive outcomes for those who take part in the practice (Ein et. al., 2018; Feng et. al., 2021; Mapes & Rosén, 2016; Nieforth et. al., 2021). Common goals that are targeted via AAT include anxiety and related symptoms, depression and related symptoms, coordination, fine motor skills, reaching, hand-eye coordination, body balance, body awareness, communication, and relationship building (Ein et. al., 2018; Feng et. al., 2021; Mapes & Rosén, 2016; Nieforth et. al., 2021). Even with the …

A Guide For Occupational Therapists: Utilizing Equine-Assisted Therapy For Children In The Foster Care System Dealing With Trauma, Alexis Skogen

Occupational Therapy Capstones

In 2015, over three million children who were affected by trauma or abuse were reported to Child Protective Services (Papovich, 2019). “Children in the foster care system have often been exposed to traumatic experiences such as violence, illicit substances, and neglect” (Crabill & Hanson, 2018, p.8). Adverse childhood experiences (ACEs) can be similar to experiencing trauma; children, prior to entering the foster care system, often experience ACEs (Craig, 2020). Children in the foster care system face hardships such as being taken out of their homes, passing through multiple homes, in addition to other childhood traumas they experience prior to their …

Sarkar, Eric Lobel, Evans Lespinasse, Zoya Vinokur, Analia Basilicata, Sonia Orellana, Maria Orellana, Aaliyah Salmon, Joanna Syska, Aravis Mcbroom, Jian Wang, Anam Riaz, Jodi-Ann Douglas

Publications and Research

Radiology departments have contributed significantly to greenhouse gases including release of toxic imaging contrast media to environment. We feel Radiology also has several spectroscopy and imaging tools that may apply to monitor and support cleaner environmental goals. The current manuscript is one of the firsts to prompt Radiology to move in that direction by non invasive imaging of bio metals that are less abundant in biological tissues but play key roles as co-factors in tissue structure and function. Conventional analytical tools are mostly invasive and cannot characterize the native oxidation states of bio metals. We chose carbohydrate matrix of metal-rich …

Climate Change And Modern State Common Law Nuisance And Trespass Tort Claims, Jack Wold-Mcgimsey

University of Colorado Law Review

This Comment examines the use of state common law tort claims to address climate change. The aim of this work is not to provide an in-depth examination of these issues, but rather to provide a contextualized and comprehensive overview of some of the most important issues in this field using modern cases actively being litigated. This Comment comes to the conclusion that the future of common law nuisance and trespass claims in the context of climate change is, for now, unclear. Given the national and global implications of climate change, courts may find that isolated states cannot set binding precedents …

Producing Procedural Inequality Through The Empirical Turn, Danya Shocair Reda

University of Colorado Law Review

Procedural rulemaking and scholarship have taken an empirical turn in the past three decades. This empirical turn reflects a surprising consensus in what is otherwise a highly divided field and an inherently adversarial system. Because procedural rules distribute legal power in society, they invariably raise questions about who should have access to courts, information, and the means to defend one's legal rights. While debate rages about these normative commitments, procedure has developed a surprising epistemic agreement on empiricism, with its promise of rising above these competing interests with data. In procedure, the turn toward empiricism has become a strategy for …
