Lessons Not Learned, Kyle Missbach

War, Diplomacy, and Society (MA) Theses

In July 1936, Spain descended into chaos and civil war. Fascists in the military, Catholic Church, and aristocracy rebelled against a government elected to reform centuries old power structures. The United States reacted in surprise and joined France and Britain, staunchly refusing to be involved. For six months, the Department of State impeded attempts to material assist the Spanish government, until Congress passed an updated neutrality law prohibiting trade with Spain or the rebels. Congress again renewed and updated the law a year later. Yet in spring of 1939, at the end of the war, Franklin D. Roosevelt told his …

Healing Through Humanitarian Design: Understanding The Refugee Crisis And Designing For The Future, Matthew Peikert

Architecture Theses

This project is an exploration into understanding the qualities of the built environment to attain a level of dignity for refugees in their healing process. Architecture cannot solve these social issues but seeks to understand the impact of the built environment on individual people. This research will focus on the humanitarian design response method and how it can be improved in the future. Can healing take place through design created by architects and does the design of a refugee camp have anything to do with that healing process? This research will use the global refugee situation as a vehicle to …

Xylan Fast Pyrolysis: An Experimental And Modelling Study Of Particle Changes And Volatiles Release, F Cerciello, E Freisewinkel, A Coppola, C Ontyd, D Tarlinski, Martin Schiemann, Osvalda Senneca, Pierro Salatino, C Allouis, Victor Scherer, Thomas H. Fletcher

Faculty Publications

Biomass char particles produced by pyrolysis may have different morphologies, which has important implications on burning mode, conversion rate and boiler efficiency. These features are difficult to address due to the complexity of biomass structure and pyrolysis reaction models. The present work reports preliminary results on the morphological changes and volatile release that solid particles of Xylan experience upon fast heating in a Drop Tube Reactor (DTR) and in a Heated Strip Reactor (HSR) in a range of temperature between 1100 and 1573 K under inert atmosphere with heating rate in the order of 10³ K/s. Two different Xylan …

Understanding And Addressing The Individualized Emotional Impact Of Aphasia: A Framework For Speech-Language Pathologists, Tyson G. Harmon

Faculty Publications

Emotion plays an integral role in communication and has long been considered relevant to aphasia rehabilitation. Speech-language pathologists (SLPs), however, may sometimes wonder how or whether to address emotional responses. The purpose of the present tutorial was to (1) present a framework that clinicians can use to understand individualized emotional responses in aphasia and (2) discuss examples of how the framework informs practical strategies that SLPs can use to provide emotional support to PWA. Drawing upon a cognitive-motivational-relational theory of emotions perspective combined with emerging research in aphasia, I show that emotion impacts and is impacted by both language processing …

The Contracts Word List: Integral Vocabulary For Reading And Writing English Contracts, Elizabeth Hanks, Brett James Hashimoto, Jesse Egbert

Faculty Publications

Both Business English as a Lingua Franca (BELF) and Legal English as a Lingua Franca (LELF) users engage with legal contracts regularly. However, contractual language is notoriously complex, due in part to the vocabulary it contains. To help mitigate the challenges related to learning the vocabulary of contracts, this paper introduces a word list of American English contracts called the ContractsWord List (CWL).We describe the compilation of the Corpus of English Business Contracts (CEBC) that represents six major contract types in 48 million words. The extraction of prevalent and specialized words from the CEBC is described, following validation procedures in …

Academic Communities Of Engagement: Exploring The Impact Of Online And In‑Person Support Communities On The Academic Engagement Of Online Learners, Kristian J. Spring, Charles R. Graham, Courtney N. Hanny, Sara Tuiloma, Kamal Badar

Faculty Publications

Institutions of higher education are interested in supporting the academic success of their students in the most effective ways possible. Increasingly, this means engaging students in a blend of both online and in-person learning activities as well as connecting students with supportive communities in both modalities. This research explores the efforts of an institution that is trying to create positive post-secondary learning experiences for thousands of adults who have experienced significant barriers to accessing higher education through traditional routes. Students around the world are supported through both online and local, in-person communities created to support their academic engagement. In this …

Regulating Gender Diversity: Evidence From California Senate Bill 826, Abigail Allen, Aida Wahid

Faculty Publications

Do gender diversity quotas enhance firm value? This broad question has sparked significant debate because while diversity is generally thought to improve board functioning, prior research in international settings suggests mandating diversity may have adverse consequences if it moves firms away from market equilibrium. Exploiting the political events leading up to the passage of California Senate Bill 826 as an exogenous shock to assess the market implications of board gender composition, we document either significantly positive or insignificant 2-day abnormal returns for California firms across a variety of model specifications. Importantly, this finding contradicts the strong claims of contemporary studies …

Costs And Benefits Of A Risk-Based Pcaob Inspection Regime, Brant E. Christensen, Nathan J. Newton, Michael S. Wilkins

Faculty Publications

We investigate the costs and benefits of the PCAOB’s risk-based inspection regime by studying how auditors respond to engagement-level inspection risk. Using an established inspection selection model, we find evidence that auditors behave consistent with accountability theory when auditing clients with elevated ex-ante inspection risk. Specifically, we observe an increased propensity to report material weaknesses, a decreased propensity to assert that previous material weaknesses have been remediated, increased audit effort, and a decreased likelihood of subsequent financial statement restatement. In general, these outcomes reflect auditors’ attempts to minimize negative inspection outcomes in a way that could be beneficial to investors. …

The Intellectual Structure Of Audit Committee Research: A Bibliometric Analysis (1969 – 2020), Joel Behrend, Marc Eulerich, David A. Wood

Faculty Publications

The audit committee is a widely recognized mechanism of effective corporate governance. We advance prior literature reviews by using bibliometric analysis techniques that comprehensively process large bodies of bibliometric information. We base inferences on citation patterns of 1,173 articles to identify concepts that “shine through” within the scientific understanding of audit committees. Using content analysis, we then analyze these concepts and explore existing interrelationships. We document a declining influence of audit committee research, as well as a widening gap between the quantitative and qualitative research camps. While the former is mostly derivative in nature, the latter produces innovative insights on …

Triangulating The Likelihood Of Confusion: Linguistics And Consumer Surveys, Eric D. Derosia, Jesse Egbert, Thomas Lee

Faculty Publications

This Article highlights contributions that linguistic analysis can offer in the assessment of the likelihood of confusion in trademark infringement cases. Parties in such cases often engage an expert witness to conduct a survey that measures the likelihood of consumer confusion. We show how an expert linguist can provide important, nonintuitive dynamics of corroboration. We introduce “expert triangulation” as a conceptual framework to analyze whether, and to what extent, experts in linguistics and consumer surveys can corroborate one another. That is, having two different sources of empirical evidence which lead to similar conclusions should be a benefit to the courts, …

Media Conglomeration, Local News, And Capital Market Consequences, Travis Dyer, Mark Lang, Jun Oh

Faculty Publications

We examine the effect of news media consolidation on local business coverage and its consequences for firms, investors, and capital markets. Using television transcripts, we find a substantial drop in coverage of local firms following the consolidation of local television stations associated with Sinclair acquisitions. Local information search, institutional portfolio local bias, and overall retail trading decrease for firms in treated geographic areas. Results are most pronounced for small firms, for stations with higher ex ante viewership, and for stations with greater reductions in local coverage. Our results provide insight into the consequences of media consolidation for local business coverage, …

Traditional Investment Research And Social Networks: Evidence From Facebook Connections, Travis Dyer, Gerrit Köchling, Peter Limbach

Faculty Publications

We show that investors acquire more public information about firms to which they are more socially proximate. On average, a standard deviation increase in the Social Connectedness Index (Bailey et al., 2018) between a firm’s headquarter county and a searcher county is associated with 30% more EDGAR filing downloads from the searcher county. The effect of social proximity on traditional investment research is distinct from the effect of geographic proximity. We find similar results studying headquarter relocations, investor-level data, and EDGAR downloads from European regions, for which physical distance should be irrelevant. Social proximity matters more during times of high …

“Words Of Plainness” Jacob’S Apology, His Addendum, And The Competing Forms Of Nephite Worship, Dan Belnap, Rob Hernandez

Faculty Publications

Jacob’s powerful essay in Jacob chapters 4–6 ends with this statement: “I bid you farewell, until I shall meet you before the pleasing bar of God, which bar striketh the wicked with awful dread and fear. Amen” (Jacob  6:13). The essay represents Jacob’s teachings as a Nephite priest concerning the centrality of Christ in the religious and doctrinal framework of his Nephite congregation. It fits within the greater structure of the book of Jacob, which appears to be governed by Nephi1’s instructions concerning what should be included on the small plates. Recorded by Jacob in Jacob 1, the instruction suggests …

Parent Motivations For Enrolling Their Young Children In Early Childhood Programs: An Application Of The Theory Of Planned Behaviour, Rachel A. Mcgovern, Camilla Hodge, Edward Ruddell

Faculty Publications

This study used the theory of planned behaviour to identify and determine the relative influence of factors influencing parents’ decisions to enrol their young children (3 to 5 years old) in early childhood programs at a specific museum venue. An eliciting questionnaire was distributed to museum members with at least one child 3–5 years old to elicit outcome expectancies, normative beliefs, and control beliefs, and these responses were developed into items for the main questionnaire. Regression and correlation analyses were conducted to determine factors associated with parents’ intention to enrol their children. Parents across socioeconomic and educational backgrounds indicated they …

Moral Decision-Making In Organizations, Maryam Kouchaki, Isaac Smith

Faculty Publications

Research on moral decision-making in organizations has expanded significantly over the past few decades. In this review, we build on prior comprehensive reviews on the topic to provide an updated view of the field, based on the latest findings. We first provide a brief historical overview of influential theories of moral decision-making and then describe the individual characteristics, interpersonal factors, and organizational factors that have been shown to influence people's morally relevant choices, as well as the cognitive, affective, and even physiological processes at play. We then provide a more critical view of the field and focus on what we …

Organizational Ghosts: How “Ghostly Encounters” Enable Former Leaders To Influence Current Organizational Members, Jeffrey S. Bednar, Jacob A. Brown

Faculty Publications

Leadership research has assumed that leader group prototypicality enhances leadership influence during a leader’s tenure. Other leadership research has also assumed that leaders, especially founders, can transformtheir leadership influence into a legacy thatwill survive death and departure from the organization and continue to impact followers. However, to understand the historically embedded nature of leadership influence, it is critical to unpack how specific leaders can become group prototypes and influence followers after their departure. We address this opportunity by examining organizational ghosts—former organizational members who become the ideal prototype of an organization’s values and identity. Drawing on qualitative data from an …

Drug-Resistant Epilepsy And Ketogenic Diet Therapy – A Qualitative Study Of Families’ Experiences, Jennifer H. Carroll, Tracey Parkin, J. Helen Cross, Mary Hickson, Emma Williams, Val Aldridge, Avril Collinson

School of Health Professions

Background: A diagnosis of drug-resistant epilepsy is life changing for a family. Ketogenic diet therapy (KDT) can offer hope when other treatments have failed. However, it often requires a significant change in daily routine and dietary habits. This qualitative descriptive study aimed to explore families’ experiences of epilepsy and KDT. Methods: Parents of a child aged ≤18 years with epilepsy, currently or recently treated with KDT, were recruited from the UK and internationally via UK Ketogenic Diet (KD) centres, charities, and social media. Semi-structured interviews were audio recorded, transcribed verbatim, anonymised, coded using Nvivo (V12), and inductive thematic analysis undertaken. …

Aspects explored included chromatic and luminance mechanisms, retinal location, size and scaling, binocular interactions and effects of simulated scotoma, concentric and eccentric presentation, and interval and spatial methods. …

The Integration Of Multiple Cardiovascular And Pulmonary Models Into A Single Unified Cardiopulmonary Model, Julian Iii Thrash

Electrical and Computer Engineering

There has been an increasing effort to employ cardiovascular (CV) and pulmonary models to assist in the study of disease, answer research questions, and study the effects of a medical treatment or device. To properly study the intricate dynamics of the CV and pulmonary systems, a comprehensive model is required to achieve a holistic understanding of its mechanics and view the emergent properties of the complex and dynamic cardiopulmonary system. This study builds on the work of Mauro Ursino et al., by taking their multiple CV and pulmonary models and integrating them together within the scalable environment of MATLAB and …

Study Protocol For Measuring Stigmatization In Persistent Tic Disorders: Development And Validation Of The Tourette Discrimination-Stigmatization Scale, Jaclyn M Martindale, Victor M Ringheanu, Kelly A Pring, Sandra Norona, Kimberly Wiseman, Roy E Strowd, Leah Chapman, Joseph Rigdon, Stephen R Rapp, Eric A Storch, Edward Ip, Jonathan W Mink

Center for Medical Ethics and Health Policy Staff Publications

Introduction: Persistent Tic Disorders such as Tourette Syndrome are common neurodevelopmental disorders that are highly stigmatized. Many individuals with Persistent Tic Disorders experience peer rejection, loneliness, and self-stigma. Experiencing stigmatization during childhood can influence the persistence of moderate-to-severe tics later in life. Additionally, these factors have been associated with increased suicidal ideation, suicide attempts, and psychiatric symptom severity. There is a need for interventions to reduce stigma and stigmatization in Persistent Tic Disorders. Before developing cost-effective interventions to mitigate stigma's profound downstream health impacts, a reliable measure of stigmatization must be created. The overarching goal of this research is to …

Choosing Your “Healthiest” Embryo After Dobbs: Polygenic Screening And Distinctive Challenges For Truth In Advertising And Informed Consent, Dov Fox, Sonia Suter, Meghna Mukherjee, Stacey Pereira, Gabriel Lázaro-Muñoz

Center for Medical Ethics and Health Policy Staff Publications

Polygenic embryo screening ("PES") analyzes embryos for hundreds or thousands of genomic loci to generate risk scores that estimate genetic susceptibility to conditions and traits compared to the general population. The technology is commercially marketed directly to consumers. Companies focus mostly on medical conditions, sometimes in ways that oversell its advantages and efficacy, encouraging fertility patients to "choose your healthiest embryo" and "protect your future child from genetic risks." The advertising of PES trades on norms of children's health and good parenting and reinforces those normative ideals. While it is easy to assume PES will be constrained in practice by …

Development Of A Multi-Level/Multi-Modal Intervention For Health Care Transition Preparation, Beth H Garland, Mary Majumder, Constance M Wiemann, Blanca Sanchez-Fournier, Jordyn Babla, Albert C Hergenroeder

Center for Medical Ethics and Health Policy Staff Publications

Aims: Health care transition (HCT) to adult care and young adult disease self-management is a multi-step process involving three major stakeholders - the adolescent, the caregiver, and the provider. Preparation gaps exist within each of these stakeholder groups. This paper presents the development of the Intervention to Promote Autonomy and Competence in Transition-aged Youth (IPACT), a multi-level (adolescent, caregiver, provider), multi-modal (interactive skill building sessions, educational materials, videos) intervention to address gaps in all three stakeholder groups simultaneously and help support achieving the three core elements of HCT planning.

Methods: Eight processes were utilized to develop the IPACT intervention, including …

Public Perspectives On Investigative Genetic Genealogy: Findings From A National Focus Group Study, Jacklyn Dahlquist, Jill O Robinson, Amira Daoud, Whitney Bash-Brooks, Amy L Mcguire, Christi J Guerrini, Stephanie M Fullerton

Center for Medical Ethics and Health Policy Staff Publications

Background: Investigative genetic genealogy (IGG) is a technique that involves uploading genotypes developed from perpetrator DNA left at a crime scene, or DNA from unidentified remains, to public genetic genealogy databases to identify genetic relatives and, through the creation of a family tree, the individual who was the source of the DNA. As policymakers demonstrate interest in regulating IGG, it is important to understand public perspectives on IGG to determine whether proposed policies are aligned with public attitudes.

Methods: We conducted eight focus groups with members of the public (N = 72), sampled from four geographically diverse US regions, …

Inorganic Chemical Reasoning Skills: An Exploratory Study Into Understanding Students’ Choices And Thought Processes, Hannah P. Thompson

Graduate Theses/Dissertations

Predicting the products of reactions is a fundamental skill for practicing inorganic chemists. However, the current knowledge of the strategies that students use to solve them is limited. Presumably, instructors of inorganic chemistry courses give complete-the-reaction assessment items hoping that students will use their knowledge of inorganic concepts to solve them; but it is conceivable that a successful student could use heuristics or domain general problem-solving methods. I proposed this study to determine which strategies were used by students when solving complete-the-reaction tasks in inorganic chemistry, and also to make qualitative connections between strategy and accuracy. This was done in …

Assessing Interatomic Potentials For Molecular Dynamics Simulation Of Soybean Oil Pyrolysis, Tanner Garrett Rust

Graduate Theses/Dissertations

The world today relies on hydrocarbon combustion for many reasons, including its high energy density that provides ease of transportation. However, hydrocarbons sourced from fossil fuels are not expected to last forever. Biodiesel, a renewable alternative, has many attractive benefits but comes with other downsides. Biodiesel can gel in cold environments and may leave residue in an engine. Pyrolysis of biodiesel has shown promise in addressing these common detriments. Inducing pyrolysis on biodiesel feedstock (commonly soybean oil in the USA) would be an attractive option presuming it continues to produce fossil fuel analogs similar to biodiesel pyrolysis. Herein, Langevin molecular …

The Kinetic Modulation Of Α - Synuclein Fibrillation And Toxicity By 4-Phenylbutyric Acid, Kristos Awuah Baffour

Graduate Theses/Dissertations

ABSTRACT

The Protein misfolding and aggregation of alpha-synuclein (α-syn) into neurotoxic amyloids underlies the pathogenesis of neurodegenerative diseases such as Parkinson's disease (PD). 4-Phenylbutyrate (PBA), an FDA drug approved for treating urea cycle disorders, has garnered significant attention as a potential chemical chaperone for targeting alpha-synuclein (α-syn) aggregation. Using in vitro assays, we demonstrated that PBA treatment alters the pattern of α-syn aggregation, as evidenced by reduced formation of oligomeric species and its increased susceptibility to proteolytic cleavage under the influence of PBA. Proteinase K assay, surface plasmon resonance, and Nile red studies indicate that PBA interacts with the extensive …

Enhancing Workplace Climate And Learning Outcomes In Aba Services: Prosocial Approaches And Peak Instruction With Autistic Learners, Stephanie Vickroy

Graduate Theses/Dissertations

The practice of Applied Behavior Analysis (ABA) heavily relies on the relationship between high quality client services and the direct care staff who implement these services. This thesis combines two manuscripts which discuss the field of behavior analysis in terms of clinical approaches. The first chapter evaluated intervention outcomes of 55 autistic learners undergoing language and cognitive training guided by PEAK (Promoting Emergence of Advanced Knowledge System; Dixon, 2014) within ABA services. Pre-post analyses of performance on the PCA revealed significant increases in PCA scores following 6-months of intervention and consistent gains in scores occurred across all four …

Evaluating The Normative Development And Efficacy Of The Life Functional Module, Kaitlyn A. Hui

Graduate Theses/Dissertations

The Life Functional Module (Dixon, 2020) is an all-encompassing assessment and curriculum designed to promote learner’s independence and well-being by teaching daily living, social, leisure, and other functional or meaningful skills. There is a wide variety of curricula that is currently used in applied-behavior analysis services and programming, including the Essentials for Living, Assessment of Functional Living Skills (AFLS), and the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP). However, there is a lack of research in empirical evidence in regards to the efficacy of these curricula (Ackley et. al, 2019; Padilla et. al, 2023). The first manuscript of this …

Evaluating The Maintenance Of Verbal Relational Operants Following Peak Programming, Jenna Huskey

Graduate Theses/Dissertations

The Promoting the Emergence of Advanced Knowledge (PEAK) Relational Training System is an assessment and curriculum tool developed for basic and advanced language skills using behavior analytic approaches (Dixon, 2016). Maintenance describes the retention of performance following the progression of time. In the present study, the purpose was to determine if maintenance was achieved on previously mastered PEAK programs, both in terms of the content and the verbal relational operant (i.e., generalization to new, untrained content). De-identified data were analyzed for five autistic learners (six to fourteen years old) receiving ABA services at a Midwestern clinic. Programs were selected from …
