Increasing vegetable intake and diversity are recommended to maintain better health. Evidence for the health benefits of vegetable diversity, separate from total intake, is scarce. We aimed to investigate the associations of vegetable diversity with subclinical measures of atherosclerosis and atherosclerotic vascular disease (ASVD) mortality.

Making It Personal: Developing Sustainability Leaders In Business, Aoife Brophy Haney, Jenny Pope, Zoe Arden

Research outputs 2014 to 2021

Sustainability challenges present organizations in many industries with the need to change. Leaders are critical to the process of becoming more sustainable, and yet leading change for sustainability requires new competencies. Learning at an individual level is central to developing new competencies; however, there has been limited focus to date in the literature on corporate sustainability on how leaders can learn to respond to sustainability challenges. In this article, we focus on how managers learn to become sustainability leaders in their organizations by exploring the phenomenon of experiential learning programmes. We do this by interviewing participants and organizers of four …

The Emotion Regulation Questionnaire: Psychometric Properties In General Community Samples, David A. Preece, Rodrigo Becerra, Ken Robinson, James J. Gross

Research outputs 2014 to 2021

The Emotion Regulation Questionnaire (ERQ) is a 10-item self-report measure of 2 emotion regulation strategies, cognitive reappraisal and expressive suppression. It is a widely used measure of emotion regulation, but its factor structure has rarely been examined outside of university student samples, and some authors have recently questioned its factorial validity in general community samples. In this study, we examine the psychometric properties of the ERQ (original English version) in 3 Australian general community samples (N = 300, 400, 348). Confirmatory factor analyses in each sample demonstrated that the traditional 2-factor model (comprised of cognitive reappraisal and expressive suppression factors) …

Influence Of Droplet Velocity, Spacing, And Inter-Arrival Time On Line Formation And Saturation In Binder Jet Additive Manufacturing, Trenton Colton, Nathan B. Crane

Faculty Publications

Binder Jetting (BJ) is a low-cost Additive Manufacturing (AM) process that uses inkjet technology to selectively bind particles in a powder bed. BJ relies on the ability to control, not only the placement of binder on the surface but also its imbibition into the powder bed. This is a complex process in which picoliter-sized droplets impact powder beds at velocities of 1-10 m/s. However, the effects of printing parameters such as droplet velocity, size, spacing, and inter-arrival time on saturation level (fraction of pore space filled with binder) and line formation (merging of droplets to form a line) are unknown. …

Using Accelerometer And Gyroscope Data In Common Mobile Devices To Assess Credibility, Joseph S. Valacich, Jeffrey L. Jenkins, Michael D. Byrd, David Kim, Manasvi Kumar, Parker A. Williams

Faculty Publications

An observational study examined the efficacy of using accelerometer and gyroscope (i.e., orientation) data from standard mobile devices to assess response credibility. Study participants played twenty rounds of a card game where they self-reported whether they won or lost each round. Participants received a base payment but could gain increased “bonus” payments by cheating. After the card game, participants were asked a “Yes-No” question whether they cheated while their orientation data was captured. We predicted that people concealing information about an adverse behavior (i.e., cheating), would result in differences in both absolute magnitude changes in acceleration and in rotation, as …

Too Busy To Be Manipulated: How Multitasking With Technology Improves Deception Detection In Collaborative Teamwork, Nathan W. Twyman, Jeffrey G. Proudfoot, Ann-Frances Cameron, Eric Case, Judee K. Burgoon, Douglas P. Twitchell

Faculty Publications

Deception is an unfortunate staple in group work. Guarding against team members’ deceptive tactics and alternative agendas is difficult and may seem even more difficult in technology-driven business environments that have made multitasking during teamwork increasingly commonplace. This research develops a foundation for a nuanced theoretical understanding of deception detection under these conditions. The intersection of information technology multitasking and deception detection theories is shown to produce various and sometimes competing ideas about how this type of multitasking might affect truthfulness assessments in real-time teamwork. A laboratory study involving a collaborative game helped evaluate the different ideas using manipulated deception …

Design Principles For Signal Detection In Modern Job Application Systems: Identifying Fabricated Qualifications, Nathan W. Twyman, Steven J. Pentland, Lee Spitzley

Faculty Publications

Hiring a new employee is traditionally thought to be an uncertain investment. This uncertainty is lessened by the presence of signals that indicate job fitness. Ideally, job applicants objectively signal their qualifications, and those signals are correctly assessed by the hiring team. In reality, signal manipulation is pervasive in the hiring process, mitigating the reliability of signals used to make hiring decisions. To combat these inefficiencies, we propose and evaluate SIGHT, a theoretical class of systems affording more robust signal evaluation during the job application process. A prototypical implementation of the SIGHT framework was evaluated using a mock-interview paradigm. Results …

Organizations And Communities: A Symbiosis View, Hani Safadi, Richard Watson, Tanner Skousen

Faculty Publications

How can organizations and communities engage in mutually beneficial relationships? We develop a framework that explains how an open community’s engagement with an organization can be mutually beneficial to both in the long-term. We theorize how a symbiotic relationship between organizations and communities can be achieved by nurturing various forms of capital flow between organizations and communities as well as creating virtuous feedback loops within each other’s capital creation systems.

Open Communities And Formal Organizations: A Symbiosis View, Tanner Skousen, Hani Safadi, Richard Watson

Faculty Publications

How can formal organizations and open communities engage in mutually beneficial relationships? We develop a framework that explains how an open community’s engagement with a formal organization can be mutually beneficial to both in the long-term. We theorize how a symbiotic relationship between open communities and formal organizations can be forged by nurturing various forms of capital flow between them as well as creating virtuous feedback loops within and across each other’s capital creation systems. The framework has implications for understanding innovation in ecosystems and networked economies.

Exploring Antecedents And Consequences Of Managerial Moral Stress, Justin B. Ames, James Gaskin, Bradley D. Goronson

Faculty Publications

The legitimacy of moral stress as a distinct form of general stress has long been debated in previous research. Moreover, individual-level antecedents of moral stress are yet to be tested among executives. This study investigates role identity saliency (by calculating the total saliency of roles and competition between roles) as an individual- level antecedent of managerial moral stress and turnover intent as a consequence of managerial moral stress among high-level strategic decision makers in organisations. We also analyse the moderating effect of moral attentiveness in these relationships. Survey data were collected from 264 strategic decision makers from small to large …

Team Design Thinking, Product Innovativeness, And The Moderating Role Of Problem Unfamiliarity, Varun Nagaraj, Nicholas Berente, Kalle Lyytinen, James Gaskin

Faculty Publications

Team design thinking in new product development (NPD) refers to a set of design-oriented principles that can be embedded in the everyday routines of NPD teams. We theorize that team design thinking enables NPD teams to develop more innovative products––products that are useful and novel––by reducing the routine and cognition-based inertia that constrains the team’s innovativeness. Through a study of 247 NPD projects, we investigate the relationships between team design thinking, product utility, and product novelty. Further, we also explore whether the team’s unfamiliarity with product contexts influences these relationships. Findings show that team design thinking is positively associated with …

Head Fakes, Offensive Schemes And Counter Plays: Why Motivation Matters, Dawan Coombs

Faculty Publications

Dominic’s Oregon Ducks hat caught my eye as I entered his classroom. Although Autzen Stadium was more than 800 miles away, the Ducks were on the cusp of college football greatness and this kid knew it. He looked like a football player and, as we talked, football topped the list of things he loved—followed by wrestling, long boarding, biking, and the outdoors. When I asked if there was anything he didn’t like, he chuckled and said, “Reading.” Dominic (student names are pseudonyms) proceeded to explain that he never finished books because it felt hard to focus and because he read …

Cortical Neurophysiologic Correlates Of Auditory Threshold In Adults And Children With Normal Hearing And Auditory Neuropathy Spectrum Disorder, Garrett Cardon, Anu Sharma

Faculty Publications

Purpose: Auditory threshold estimation using the auditory brainstem response or auditory steady state response is limited in some populations (e.g., individuals with auditory neuropathy spectrum disorder [ANSD] or those who have difficulty remaining still during testing and cannot tolerate general anesthetic). However, cortical auditory evoked potentials (CAEPs) can be recorded in many such patients and have been employed in threshold approximation. Thus, we studied CAEP estimates of auditory thresholds in participants with normal hearing, sensorineural hearing loss, and ANSD. Method: We recorded CAEPs at varying intensity levels to speech (i.e., /ba/) and tones (i.e., 1 kHz) to estimate auditory thresholds …

The Absence Of A Religiolect Among Latter-Day Saints In Southwest Washington, Joseph A. Stanley

Faculty Publications

The term religiolect was coined by Benjamin Hary (1992, xiii) to describe a variety of language used by a distinct religious community, originally within the context of the Jewish linguistic spectrum. Religion has been shown to play an important role in various aspects of language, such as Arabic loanword adoption among Telugu speakers (Salami 2010), Persian loanwords and greetings among English-speaking Bahá’is (Masumian 2015), fluency in Sanskrit (Christian 1976), language choice among Hindus in the United States (Pandharipande 2010), maintenance of Hakka in East Malaysia (Ding and Goh 2020), and prevalence of linguistic fossils in Jewish Malayalam (Gamliel 2017). “Christianese,” …

Back Vowel Distinctions And Dynamics In Southern Us English, Joseph A. Stanley, Margaret E. L. Renwick

Faculty Publications

We investigate low/back vowels /u, oʊ, ʊ, ɔ, ɑ/ in Southern American English (SAE).

Research on SAE has analyzed changes in position over generational time.

Most work on trajectories is limited to impressionistic coding (“loss of upgliding”) or reduces trajectories to summary statistics (vector length, rate of change).

We analyze both the position and the shape of back vowels’ formant trajectories in apparent time, using new data from the Digital Archive of Southern Speech (DASS).

The View Of Southern Vowels From Large-Scale Data, William A. Kretzschmar Jr., Margaret E. L. Renwick, Katherine I. Kuiper, Lisa M. Lipani, Michael L. Olsen, Rachel M. Olsen, Joseph A. Stanley

Faculty Publications

Abstract:

We have extracted c. 2 million tokens of vowels from a rigorous sample of 63 speakers across the American South in an NSF-funded project for forced alignment and automatic formant extraction. We show how our vowel measurements across the whole region differ from national mean F1/F2 scores. We contrast men and women, and African Americans and non- African Americans, within the Southern region.

Contextual Information In Social How-To Questions That Initiate Documentation, Matt Baker

Faculty Publications

This study introduces social question-and-answer (SQA) documentation to technical and professional communication scholarship. It conceptualizes SQA as interactive, user-generated documentation and describes contextual information types within social how-to questions that initiate documentation. It also explores whether contextual information associates with answers that complete the interactive documentation. Results reliably describe 15 information types based on content analysis of 3,529 contextual information types from 500 questions. Exploratory statistical analysis suggests that askers may increase answerability by including less speculative thought, more error messages, and less general situation information. To facilitate complete SQA documentation, the study calls for additional research into question content …

Comparison Of Pyrolysis Of Live Wildland Fuels Heated By Radiation Vs. Convection, Mohammad-Saeed Safdari, Elham Amini, David R. Weise, Thomas H. Fletcher

Faculty Publications

During wildland fires, which include both planned (prescribed fire) and unplanned (wildfire) fires, live and dead plants may be subject to both radiative and convective heat transfer mechanisms. In this study, the pyrolysis of 14 live plant species native to the forests of the southern United States was investigated using a flat-flame burner (FFB) apparatus under three heating modes in order to mimic pyrolysis of plants during wildland fires. The heating modes were: (1) radiation-only, where the plants were pyrolyzed under a moderate heating rate of 4 °C s−1 (radiative flux of 50 kW m−2); (2) convection-only, where the FFB …

Modeling The Influence Of Changes In Aliphatic Structure On Char Surface Area During Coal Pyrolysis, He Yang, Thomas H. Fletcher, Yang Li, Lijun Jin, Sufen Li, Yan Shang, Haoquan Hu

Faculty Publications

The influence of changes in aliphatic structure on char surface area during coal pyrolysis was modeled, and the effect was introduced to a previous char surface area model for lignite pyrolysis established based on the chemical percolation devolatilization (CPD) model. The modified model can predict not only the N2 and CO2 char surface area during rapid pyrolysis of three lignites but also the CO2 char surface area of two high-volatile bituminous coals; the agreement of the modified model with experiments is improved at high temperatures. The decrease in aliphatic chain length can reduce adsorption positions around aromatic core, and decrease …

Analysis Of Gluten In Dried Yeast And Yeast-Containing Products, Laura K. Allred, Mitchell G. Nye-Wood, Michelle L. Colgrave

Research outputs 2014 to 2021

Yeast are commonly used in the preparation of foods and beverages such as beer and bread and may also be used on their own as a source of nutrients and flavoring. Because of the historical connection of yeast to products made from wheat and barley, consumers maintaining a gluten-free diet can have concerns about the safety of yeast ingredients. Analyzing the safety of yeast and yeast-containing products presents some difficulties, as the yeast organisms actively degrade any gluten in the product, raising questions on the appropriateness of detection by traditional antibody-based methods. This study examines a variety of yeast and …

Chen, Emmanuel Devred, Martin Gade, Eulàlia Gràcia, Jochen Horstmann, Diego Macías, Joseph M. Maina, Pere Masqué Barri, Nicholas Meskhidze, Luis Somoza

Research outputs 2014 to 2021

The ocean is the most important subsystem of the Earth’s climate system and functions as its heart, regulating the energy distribution of the planet. It has absorbed more than 90% of the energy accumulated since 1971 and about 30% of the emitted anthropogenic carbon dioxide. As a result, water temperature rises and oceans acidify and deoxygenate, which lead to changes in oceanic circulationand biogeochemistry, to rising sea levels, to more extreme weather events, to shifts in the distribution ofspecies and migratory routes, and to loss of species and habitat diversity. Awareness of the importanceof oceans for the sustainability of the …
