The Role Of Complex Posttraumatic Stress Disorder In The Associations Between Minority Stressors And Self-Reported Suicide Likelihood In Lgbtq+ Adults., Ines Cano-Gonzalez, Ruby Charak, Roman Ronzon-Tirado, Jorge I. Cantu

Psychological Science Faculty Publications

Lesbian, gay, bisexual, trans, and queer individuals (LGBTQ+) report higher rates of suicide-related behaviors when compared to heterosexual cisgender individuals. The minority stress theory proposes that the suicide risk disparities among LGBTQ+ individuals may be explained by the additional exposure to stressors unique to their minority sexual orientation and gender identity. However, less is known about the mechanism of minority stressors and suicide risk among trauma-exposed LGBTQ+ individuals. The present study aimed to explore the role of the International Classification of Diseases, version-11 posttraumatic stress disorder (PTSD) and complex PTSD (disturbances in self-organization [DSO] + PTSD) in the associations between …

Smithian Merchant Towns And Good Government In The Wealth Of Nations, John B. Estill

Faculty Research, Scholarly, and Creative Activity

Commentators on Adam Smith’s Inquiry into the Nature and Causes of the Wealth of Nations often characterize Smith as a proponent of government in multiple areas, including security in person, property, contract, and some public goods. However, Smith understood government more expansively than people today. In volume I, book III, chapters I–IV, Smith describes the evolution of merchant towns in England that led to “good governance” that dismantled the feudal system. This limited government not only included the security provided by the formal laws and institutions. It also aligned the informal elements of individual civic ethics and self-reliance with the …

Developing An Annual Review Of The Literature, Weinstein R Amy, Szauter Karen, Duca Nicholas, Jacob Jackcy, Ismail Nadia, Pincavage Amber, Walsh Katherine, Alexandraki Irene

Faculty, Staff and Students Publications

Many national meetings and speaker series feature an "Annual Review of the Literature" (ARL) session in which an individual or team presents a sampling of articles, selected and prepared because they represent important current topics or new ideas in the discipline of interest. Despite this, there is little in the medical literature describing how to thoughtfully and systematically develop these sessions. We identify best practices that we have developed and used in the United States Clerkship Directors of Internal Medicine (CDIM) over many years. These include identification of a theme, team assembly, timeline development, search strategy and rubric development and …

Working With Physical And Virtual Manipulatives: A Systematic Review Of Affordance And Cognitive Engagement Manifested Through Implementation, Seokmin Kang, Chun-Hao Chang, Sungyeun Kim

Teaching and Learning Faculty Publications

Virtual tools are rapidly supplementing physical tools in classrooms. Although extensive research has compared the benefits of using virtual and physical manipulatives, few studies have systematically explored the learning benefits of using a physical and a virtual tool. As the major learning goal in science, technology, engineering, and mathematics (STEM) education is to help students better understand scientific and mathematical concepts and processes, this study reviewed empirical studies comparing learning performance between working with physical and virtual manipulatives published between 2000 and 2022 in Education and Psychology journals. The results revealed inconsistent patterns in learning comparison across studies even with …

Faculty, Staff and Students Publications

With growing global interest in extending not only lifespan but also healthspan, healthy aging has emerged as a central goal in biomedical research. This review provides an overview of current longevity interventions, including genetic manipulations, dietary restriction, exercise, pharmacological treatments, targeting senescence and cellular reprogramming strategies, as studied in key model organisms such as Caenorhabditis elegans, Drosophila melanogaster, and Mus musculus. We examine the limitations and challenges associated with these approaches, particularly their variability across tissues and cell types. Furthermore, we emphasize the critical role of single-cell aging atlas technologies in uncovering cell-type–specific aging patterns and molecular …

Student Participation In Informal Resolution: Examination Of Impact Factors On Recidivism And Student Perceptions Of Institutional Care And Fairness, Linnea Rose Nelson

Theses and Dissertations

This exploratory case study, conducted at the University of North Dakota (UND), examined factors influencing recidivism and student perceptions of institutional care and fairness among participants in the piloted Informal Resolution (IR) option. A restorative justice (RJ)-informed alternative to the traditional student conduct process, the IR is offered to students charged with first-time, low-level violations of UND’s code of conduct. This study aimed not only to evaluate the new process but also to respond to recent calls from scholars and practitioners for more extensive research on the intersection of RJ and student conduct outcomes. Sherman’s (1993) defiance theory provided the …

Impact Of Resin Grinding On Per- And Polyfluoroalkyl Substance Adsorption In Rapid Small-Scale Column Tests, Tihitna Gezahegn Mulugeta

Theses and Dissertations

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants with significant health risks. Among the different technologies for PFAS removal, adsorption is preferable due to low-cost, operational simplicity, and use of regenerable adsorbents. While pilot-scale fixed-bed columns are ideal for evaluating adsorption media, they are time- and resource-intensive. Rapid Small-Scale Column Tests (RSSCTs) offer a practical alternative, yet most studies have focused on granular activated carbon, with limited insight into ion exchange (IX) resins. Due to limited literature on the effect resin preparation on the performance of RSSCTs and their prediction accuracies are unexplored. This study investigates the effect of …

Investigation Of Surfactant-Enhanced Oil Recovery In High Salinity And High Temperature (Hsht) Reservoir Conditions: A Case Study In The Bakken Formation, Tomiwa Isaac Oguntade

Theses and Dissertations

This study investigates improved strategies for enhancing oil recovery (EOR) in challenging reservoir conditions by combining chemical surfactant flooding and data-driven optimization techniques. Given rising global energy demand and the depletion of conventional oil reserves, chemical EOR methods, particularly surfactant flooding, are gaining popularity for their ability to mobilize residual oil via mechanisms such as reducing interfacial tension, altering wettability, and inhibiting asphaltene formation. The research begins by examining the effectiveness of surfactant applications across various reservoir conditions, emphasizing the need for surfactants capable of withstanding challenging environments characterized by high temperatures, high salinity, and low permeability. Laboratory experiments demonstrated …

Identifying The Common Patterns Or Trends That Emerge When Analyzing Past Accidents And Incidents Involving Autopilot Systems, Christopher David Tracy

Theses and Dissertations

This study investigated to what extent over-reliance on automation, particularly autopilot systems, contributed to incidents and accidents in commercial aviation. Despite advancements in automated technologies, there is a growing concern regarding the potential consequences of pilots’ dependency on these systems. This research analyzed past key incidents to identify patterns indicating that pilots may have been inadequately prepared to assume manual control during automation failures. This study employed a qualitative approach, including semi-structured interviews with aviation professionals such as airline flight instructors, line check pilots, flight standards evaluators, and an FAA aviation safety inspector, along with qualitative surveys with professional pilots. …

Public Perceptions Of Fracking And Anti-Fracking Activism: A Theory Of Planned Behavior Approach And Its Implications For Environmental Policy, Okhumode Hector Yakubu

Theses and Dissertations

Hydraulic fracturing, or fracking, has become one of the most contentious energy technologies of the 21st century, drawing support for its economic and energy security benefits and opposition due to its perceived environmental and health risks. This study applies the Theory of Planned Behavior (TPB) to examine the psychological, social, and informational factors that shape public perceptions of fracking and motivate anti-fracking activism. Using a nationally representative sample of U.S. adults (N = 522), this research investigates how attitudes, subjective norms, perceived behavioral control, and domain-specific knowledge predict support or opposition to fracking, as well as intentions to engage in …

Languages And Nation Building, David Martinez-Prieto

Bilingual and Literacy Studies Faculty Publications

In this chapter, I analyze the ideologies behind the rationale that implies that citizens of a specific country should speak specific languages. In other words, I examine the relationship between the ideological construction of citizens and languages. I first explore notions of ideological construction explained by Weberian (1904/2002), Marxist (1872), and Geertz (1973) to provide a seminal understanding of the creation of a “collective we” embedded in nation-states. I then refer to some common academic research frameworks to analyze the ideological construction of citizenship within a nation state to differing degrees of acceptance of (Gramsci, 1948) and resistance to (Anzaldúa, …

Actuator Disk Model For Aeropropulsive Coupling Effects In Vortex Particle Method, Eduardo Alvarez, Vineet Ahuja, Vinod Lakshminarayan, Aaron Perry, Ryan Anderson, Andrew Ning

Faculty Publications

Blown lift and distributed electric propulsion aircraft pose strong aeropropulsive coupling effects that cannot be ignored during the early stages of design. In this study, we develop an advanced actuator disk model (ADM) for aeropropulsive coupling effects of ducted fans with the vortex particle method (VPM). The advanced ADM consists of (1) an actuator disk at the rotor plane, (2) a surface vortex sheet modeling the mixing and convection of blade tip vorticity along walls, and (3) a powered wake at the exhaust. With these three components, a propulsion jet with an arbitrary velocity profile is formed and interactions with …

Artificial Intelligence In Educational Research And Scholarship: Seven Framings, Eamon Costello, Giselle Ferreira, Stefan Hrastinski, Jason K. Mcdonald, Ahmed Tlili, George Veletsianos, Victoria I. Marin, Henk Huijser, Sharon Altena

Faculty Publications

In a recent interview (Bender et al., 2025), Professor Emily M. Bender discussed the limitations of technical solutions in addressing harmful Artificial Intelligence (AI) bias. She described a particular point we may reach at which technical solutions stop working, and when we should then widen the lens to ask about the problem framing itself. This is a crucial step in any inquiry that is of concern to both novice and experienced researchers alike: moving from problem-solving to problematisation. This commentary aims to provide educational researchers with a glimpse into the wide array of research problems and problematisation of AI in …

Comparing The Sensitivity And Specificity Of Novel Motor Assessments For Traumatic Brain Injury, Paula K. Johnson, Ariana M. Hedges-Muncy, Erin D. Bigler, Lorie Richards, Steven Knight Charles

Faculty Publications

Background: Portable technology that records movements with high accuracy provides potential for sensitive clinical movement tests for individuals who experienced a traumatic brain injury (TBI). Objective: (1)To present impairments assessed using markerless motion capture (MMC) and (2) to compare the sensitivity and specificity of the MMCmediated tests to each other and to common clinical tests. Design: Screening study, using as criterion standard the ability to classify participant with TBI versus control participant. Setting: Research laboratory. Participants: The study included 30 individuals with TBI and 101 control participants. Entry criteria included most recent head injury < 5 years old, no history of movement issues prior to injury, no movement-affecting medications, and sufficient cognitive ability to follow instructions. Interventions: Not applicable. Main Outcome Measures: Performance on MMC-mediated tests and existing clinical analogs. MMC-mediated tests included finger oscillation, simple reaction time, and visually guided movement tasks. For comparison, participants also completed the following clinical tests: Halstead–Reitan finger tapping, simple reaction time test, and Beery Visuomotor Integration test. Impairments were identified as test scores of participants with TBI that fell outside of the 95% interval of control participants’ test scores. Random forest analysis was used to calculate the sensitivity and specificity of MMC and clinical tests according to their ability to correctly classify participants with TBI and control participants. Results: MMC-mediated tests revealed impairments in more participants with TBI than clinical tests in all three TBI groups (mild, repeated, and moderate to severe). Similarly, MMC-mediated tests revealed a higher percentage of scores as impairments than clinical tests in all three groups with TBI. Furthermore, MMC-mediated tests proved more sensitive and more specific than clinical tests (70% versus 50% and 98% versus 93%, respectively). Conclusion: MMC-mediated tests are sensitive and specific (compared to traditional clinical tests) and have potential to fill a gap in clinical care of TBI.

Case Study: Should A Chro Abandon Performance Improvement Plans?, Devasheesh P. Bhave, Sin Mei Cheah

Research Collection Lee Kong Chian School Of Business

At Barton Creek Technologies, Anna Chen, the chief human resources officer, faces a dilemma over the company’s performance improvement plan (PIP). Introduced as a supportive tool to rehabilitate struggling employees, the PIP has widely become perceived as a punitive mechanism. An internal audit revealed that only 15% of employees placed on PIPs complete them, while 60% are terminated and 25% go on stress-­related medical leave, often not returning. Managers admit they lack the training to implement PIPs effectively, and employees describe the plans as stigmatizing and demoralizing. Chen is torn between reforming the program into a mentorship-based system—requiring significant investment …

Business Communication And Editing Students’ Evaluations Of Written Error: An Eye-Tracking Study, Matt Baker, Grant Eck, Ana Barraza, Benjamin Duffield

Faculty Publications

Using eye-tracking and interview methods, this study investigates how business communication students and editing students attend to and evaluate writing. Participants reviewed blog posts embedded with errors and judged publication readiness. While both groups visually fixated longer on errors than non-errors, business communication students were more likely to approve error-containing texts for publication. Qualitative data revealed that business communication students prioritized content while editing students prioritized surface-level issues. These findings suggest that disciplinary background informs evaluative standards, even when error-detection behavior is similar. The results carry implications for instruction in business writing and editing, especially concerning collaborative, cross-disciplinary workplace writing.

Timing Is Everything: Congruence, Controllability, And Performance Measure Weighting, Hayden T. Gunnell, Gary Hecht, William B. Tayler, Kristy L. Towry

Faculty Publications

We investigate whether the weights managers place on performance measures for performancebased compensation depend on whether weights are determined at the beginning or end of the performance period. We propose that managers frame the weighting decision differently depending on timing. Specifically, prior to employee effort, managers frame the decision as intended to align employee effort to firm objectives, whereas after employees have exerted effort, managers frame the weighting decision as intended to evaluate employee effort. Thus, we expect, and find, that managers weight measures that are more congruent with firm objectives more heavily when weightings are determined ex ante (before …

Disclosure Benchmarking By Lawyers: Evidence Fromthe Ipo Setting, Michael S. Drake, Jeff Mcmullin, Kenneth Merkley, Chase Potter, John Treu

Faculty Publications

Lawyers play an important advisory role in drafting financial reports, yet empirical evidence documenting the influence of external legal counsel on this process remains sparse. This study focuses on a specific aspect of lawyers’ drafting process: the practice of reviewing disclosures previously filed by other issuers—a practice termed “disclosure benchmarking.” Using initial public offering (IPO) disclosures as the setting, we find that disclosure benchmarking is associated with amore efficient Securities and Exchange Commission (SEC) review process. We further find that it is associated with several measures of disclosure quality, including disclosures that are less likely to be revised in subsequent …

Signaling Innovation: The Nontax Benefits Of Claiming R&D Tax Credits, Bradford F. Hepfer, Hannah W. Judd, Sarah C. Rice

Faculty Publications

Using the IPO setting, we test whether firms signal the quality of their investments in innovation activities by claiming R&D tax credits. We find the presence and amount of the R&D credit are each associated with lower information asymmetry and with higher investor demand at IPO. Conservatively, we estimate that sample firms realize additional IPO proceeds of 32–45 percent of their creditable R&D expenditures, indicating economically significant non-tax benefits associated with the R&D credit. We verify the R&D credit signal by showing its positive association with firms’ future patenting activity, patent citations, and post-IPO stock returns. Results from these tests …

Bridging The Gap: Exploring The Potential Of Virtual Reality For Supporting Autistic Individuals In Interview And Recruitment Processes Through A Realist Review, Katie Edwards, Marius Varga, Michael Loizou

School of Nursing and Midwifery

The aim of this realist review was to systematically analyse the peer-reviewed academic literature, reports and blogs to determine: (1) the mechanisms and contexts by which recruitment and early employment experiences lead to poor outcomes for autistic adults, and (2) how a Virtual Reality (VR) intervention might lead to positive outcomes within the recruitment and early employment experiences for autistic adults. Throughout, we worked with a PPIE group of autistic people who were fully involved in the realist synthesis process. We identified challenges across the employment journey including limited vocational guidance and employment readiness support, exclusionary job descriptions, and traditional …

Flexible Furniture To Support Inclusive Education: Developing Learner Agency And Engagement In Primary School, Julia E. Morris, Wesley Imms

Research outputs 2022 to 2026

To ensure quality and equitable education requires an understanding of how all learners function within a learning environment, and the ways in which teachers’ pedagogy can support inclusive practice. Drawing on research from a rural school in Western Australia, this paper identifies how furniture can be used as a tool to support student agency and opportunity to meet individual learning needs. Across two years, the study employed a single-subject research design to explore the impact of differing furniture arrangements on students’ agency and engagement, as well as teacher pedagogies. It used both quantitative and qualitative repeated measures with 9 teachers …

Multifactorial Fall Interventions For People Over 65 Years In The Acute Hospital Setting: Pre–Post-Test Design, Allison Wallis, Christina Aggar, Deb Massey

Research outputs 2022 to 2026

Background: Falls are the most reported patient safety incident for patients >65 years in acute hospital settings worldwide. While multifactorial fall interventions reduce the number of falls in subacute and rehabilitation settings, fall interventions in acute hospital settings are unknown. Aim: To evaluate the effectiveness of multifactorial fall interventions on the number of falls using codesigned education targeting staff and the patient and review the environment in acute hospital settings in NSW, Australia for patients over 65 years of age. Method: A pre–post-test design with a non-equivalent group was conducted. All acute hospital inpatient falls occurring both pre- and post-intervention …

The Future Performance Implications Of Non-Gaap Motivated Investment, Minkwan Ahn, Theodore E. Christensen, Ryan G. Johnson, Melissa F. Lewis-Western

Faculty Publications

We investigate whether consistent non-GAAP reporting is associated with investment efficiency. Prior research finds a positive association between non-GAAP reporting and investment levels, concluding that it represents overinvestment. We corroborate this positive association, but additional tests are not consistent with the conclusion of inefficient overinvestment. Specifically, we explore the relation between investment and future cash flows as a proxy for the realization of investments in positive net present value projects. We find that the investments of firms that consistently report non-GAAP metrics are associated with similar or higher future cash flows than the investments of firms reporting only GAAP earnings, …

Price Transparency And Patient Engagement: Social Messaging Matters, Jace B. Garrett, Keaton C. Helquist, Steven D. Smith, William B. Tayler

Faculty Publications

OBJECTIVES: To examine the effects of price transparency and prosocial messaging on price-protected consumers’ health care choices as a potential cost-saving strategy to manage rising US health care expenditures.

STUDY DESIGN: Cross-sectional study. Participants were recruited to complete a basic questionnaire via Amazon’s Mechanical Turk program. Participants’ selections were subsequently collected and analyzed.

METHODS: Participants (N = 567) selected a sleep study provider from 5 options, with manipulations including financial responsibility, provision of price information, and a prosocial message encouraging high-value options.

RESULTS: Price transparency increased the selection of lower-cost options among participants who were solely responsible for paying for …

Psychological Reactance Theory And Tax Evasion Intentions, Diana Falsetta, Brian C. Spilker

Faculty Publications

This study experimentally examines how tax administration service inefficiencies in the form of tax return processing delays from paper-filed tax returns indirectly affect taxpayer tax evasion intentions through taxpayers’ psychological reactance to the delay. We further consider whether this indirect effect is different when the taxpayer willingly chooses to paper file their tax return versus when the taxpayer is forced to do so. Consistent with Psychological Reactance Theory (PRT), we find that when taxpayers receive delayed refunds, they experience psychological reactance (e.g., anger and frustration with the tax administration) that increases their tax evasion intentions. Further, we find that the …

How Deep-Level And Surface-Level Board Diversity, Formal And Informal Social Structures Affect Innovation, Guoli Chen, Po-Hsuan Hsu, Yen Teik Lee, Daniel Z. Mack

Research Collection Lee Kong Chian School Of Business

Despite a growing interest in understanding how board diversity shapes firms’ innovation, findings about the impact of board diversity have remained mixed. In this paper, we conceptualize board diversity as two forms – deep-level and surface-level – and find that these two forms of board diversity have opposing effects on a firm's innovation. We also theorize how formal and informal social structures can strengthen the positive effect of deep-level diversity yet simultaneously weaken the negative impact of surface-level diversity. We test our hypotheses with a panel of 42,432 firm-year observations from 2000 to 2019. Our paper contributes to the literature …
