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 …


Browsing Within An Academic Library, Holt Zaugg, Jillian Bunderson Jan 2025

Browsing Within An Academic Library, Holt Zaugg, Jillian Bunderson

Faculty Publications

Purpose – Browsing library resources is a method long used by researchers to expand their understanding of ill-defined projects and to have serendipitous research discoveries. This study sought to understand the browsing activities of students in an academic library. Design/methodology/approach – The study used two methods. First, a link to an online survey was posted on posters throughout the library inviting students to share their browsing experience. Second, library security officers (student employees) were asked to count the number of people browsing within the stacks as they conducted their hourly walk-throughs of the library. Browsing was broadly defined as anyone …


Designing For Relational Ethics In Online And Blended Learning: Levinas, Buber, And Teaching Interfaith Ethics, Michael Hubbard Mackay, Jason K. Mcdonald, Andrew C. Reed Jan 2025

Designing For Relational Ethics In Online And Blended Learning: Levinas, Buber, And Teaching Interfaith Ethics, Michael Hubbard Mackay, Jason K. Mcdonald, Andrew C. Reed

Faculty Publications

Online and blended learning (OBL) overemphasize the process of creating artifacts, producing strategies, or otherwise utilizing a “making” orientation in education. As an alternative to this making-orientation, we offer a model for relational course design founded in the philosophies of Emmanuel Levinas and Martin Buber. We examine an OBL course design focused on interfaith leadership and ethics that lends itself to the need for relational pedagogy. The focus on asymmetrical and symmetrical relationships that separate Levinas and Buber’s philosophies enable rich ways of designing relational pedagogies and for resisting the making orientation. By focusing on human relationships, we demonstrate design …


A Generalized Coherence Framework For Quantifying Input Contributions In Multi-Input Systems With Correlated Or Uncorrelated Inputs, Nolan H. Howes, Matthew S. Allen, Dario Farina, Steven Knight Charles Jan 2025

A Generalized Coherence Framework For Quantifying Input Contributions In Multi-Input Systems With Correlated Or Uncorrelated Inputs, Nolan H. Howes, Matthew S. Allen, Dario Farina, Steven Knight Charles

Faculty Publications

In multi-input systems, it is often necessary to quantify the contribution of each input to an output. Such contribution analysis is frequently performed using coherence. However, when correlation is present between inputs, existing coherence measures do not accurately quantify the contribution of individual inputs, except in special cases. Here we propose an expanded coherence framework that enables contribution analysis in any multi-input system, regardless of input correlation. We bridged the gap by defining three new coherence measures: component, excluded, and isolated coherence. Component coherence is an intermediate measure that decomposes measured output power into components attributable to inputs directly vs …

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.


Sources Of Influence In Marriage And Parenting For Interfaith Couples, William D. Stanford, Justin J. Hendricks, Ted G. Futris, Loren D. Marks, David C. Dollahite Jan 2025

Sources Of Influence In Marriage And Parenting For Interfaith Couples, William D. Stanford, Justin J. Hendricks, Ted G. Futris, Loren D. Marks, David C. Dollahite

Interfaith marriages are increasingly common, yet research on their family dynamics and sources of influence in family functioning remains limited. Relatedly, although research highlights religion’s influence on family processes, most studies only include same-faith couples. Subsequently, we qualitatively explored the experiences of 32 happily married interfaith couples, examining their sources of guidance in marriage and parenting, reasons for rejecting influences, and the role of religion in their family functioning. We identified one theme of rejecting outside influence and five key themes/sources of influence: one another/themselves, family, friends, media/professionals, and spiritual sources. Findings emphasize similarities between interfaith couples and American families …


Business Communication And Editing Students’ Evaluations Of Written Error: An Eye-Tracking Study, Matt Baker, Grant Eck, Ana Barraza, Benjamin Duffield Jan 2025

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.

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 Jan 2025

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 …


An House For The Lord: Solomon's Temple And Temple Worship In Ancient Israel, Dan Belnap Jan 2025

An House For The Lord: Solomon's Temple And Temple Worship In Ancient Israel, Dan Belnap

Faculty Publications

It would not be exaggeration to say that at the center of Old Testament history and theology is covenantal worship and the temple. From the Garden of Eden to the altars constructed by Abraham and the patriarchs, and the portable tabernacle of Moses, the concept of sacred space plays a fundamental role throughout biblical history and in the life of ancient Israel. But during the period of the monarchy, it became possible to construct a permanent house for the Lord. Thus, the construction and dedication of the temple are the primary subject within Solomon’s narrative arc. This chapter explores the …
