Religious Affiliation’S Association With Suicidality Across Sexual Orientations And Gender Identities, W. Justin Dyer, Michael A. Goodman

Faculty Publications

The objective was to replicate and extend earlier findings examining the intersection of sexual orientation and religious affiliation predicting suicidality. Current analyses used updated data and extended prior work by examining how affiliation relates to suicidality for transgender individuals. Data were collected in 2021 from 46,562 adolescents and were representative of Utah adolescents in grades 8, 10, and 12. In regressions, affiliation predicted suicidality and subsequent models added demographics, family functioning, drug use, feeling socially integrated, and interaction terms between sexual orientation, gender identity, and affiliation. In baseline models, affiliation was related to fewer mental health difficulties. When including drug …

Reasons For Home Educating In Australia: Who And Why?, Eileen Slater, Kate Burton, Dianne Mckillop

Research outputs 2014 to 2021

Home education is a legal educational option in Australia that continues to rise in popularity. This paper summarises the demographics and influences upon the decision to home educate of 385 home education families from Australia, representing 676 children who were home educated at the time of questionnaire completion. The research suggests female caregivers with higher levels of educational achievement than the general population predominantly coordinate home education. Some families eschewed mainstream education for philosophical reasons whilst others home educated due to perceived necessity. However, characteristic of both groups was the belief that the current education system was unable to provide …

What Sort Of ‘Inclusion’ Is Continuing Professional Development Promoting? An Investigation Of A National Cpd Programme For Inclusive Physical Education, Kyriaki Makopoulou, Dawn Penney, Ross Neville, Gary Thomas

Research outputs 2014 to 2021

Inclusion is positioned at the forefront of global educational reform. The study reported focused on a national Continuing Professional Development (CPD) programme for Inclusive Physical Education (IPE) in England. The research was designed to critically explore how CPD providers (i.e. tutors) variously conceptualised and practiced inclusion in the context of running a day-long CPD course for physical education teachers. Using qualitative methodology, data were collected via course observations (n = 27), informal interviews with tutors (n = 10), and a tutor questionnaire (n = 18). Findings suggest that although tutors’ theoretical interpretations of inclusion were largely consistent …

When Is Enough, Enough? An Examination Of Student Engagement When Watching Online Group Project Presentations, Manasvi Kumar, Joseph S. Valacich, Jeffrey L. Jenkins, David Kim

Faculty Publications

In traditional face-to-face classes, conventional wisdom suggests that delivering and watching group project presentations is a valuable learning experience. In this research, we examine the limits of student engagement and learning in an asynchronous online context. Specifically, 249 undergraduate students were assigned to perform peer evaluations of multiple ten-minute project presentations. The online learning platform collected objective viewing behavior for each student, allowing us to use viewing time as a proxy for engagement. We also collected self-reported attitudes towards the assignment, finding that while students value providing feedback, they do not consider it a valuable use of their time. Students …

Too Fast? Too Slow? A Novel Approach For Identifying Extreme Response Behavior In Online Surveys, Manasvi Kumar, Joseph S. Valacich, Jeffrey L. Jenkins, David Kim

Faculty Publications

Some participants of online surveys engage in extreme answering behavior while generating responses (i.e., they respond too fast or too slow) relative to population norms. Here, we demonstrate how participants’ navigation behaviors can be used to potentially identify such responses. We administered an online survey where students (who were earlier instructed to complete a task) report lenience scores towards non-appropriate behavior while completing the task. We draw on cognitive dissonance theory to posit that failure to follow instruction predicts lenience scores. We then created different datasets by excluding data from participants flagged by our metrics and generated predictive models. We …

Do Privacy Assurances Work? A Study Of Truthfulness In Healthcare History Data Collection, Tamara M. Masters, Mark Keith, Rachel Hess, Jeffrey L. Jenkins

Faculty Publications

Patients often provide untruthful information about their health to avoid embarrassment, evade treatment, or prevent financial loss. Privacy disclosures (e.g. HIPAA) intended to dissuade privacy concerns may actually increase patient lying. We used new mouse trackingbased technology to detect lies through mouse movement (distance and time to response) and patient answer adjustment in an online controlled study of 611 potential patients, randomly assigned to one of six treatments. Treatments differed in the notices patients received before health information was requested, including notices about privacy, benefits of truthful disclosure, and risks of inaccurate disclosure. Increased time or distance of device mouse …

What Makes Health Data Privacy Calculus Unique? Separating Probability From Impact, Mark Keith, Autumn Clark, Tamara Masters, Curtis Wigington

Faculty Publications

Patient health data is heavily regulated and sensitive. Patients will sometimes falsify data to avoid embarrassment resulting in misdiagnoses and even death. Existing research to explain this phenomenon is scarce with little more than attitudes and intents modeled. Similarly, health data disclosure research has only applied existing theories with additional constructs for the healthcare context. We argue that health data has a fundamentally different cost/benefit calculus than the non-health contexts of traditional privacy research. By separating the probability of disclosure risks and benefits from the impact of that disclosure, it is easier to understand and interpret health data disclosure. In …

Uncommon Ground: Grant Wood And Russell Lee's Divergent View Of Iowa, James R. Swensen

Faculty Publications

GRANT WOOD'S American Gothic (1930) has likely been reproduced, parodied, and lampooned more than any other painting in American history (Figure 1). As scholars Wanda Corn, Steven Biel, and others have observed, the scene of an Iowa farmer and his daughter (often erroneously thought to be his wife) has proven to be remarkably adaptable for nearly a century.¹ An early example of its adoption occurred 11 years after Wood's work was finished, when it was appropriated by Gordon Parks, a young Black photographer. Created for the Farm Security Administration (FSA) and under the aegis of administrator Roy Stryker, Parks …

Zeta Potential Of A Natural Clayey Sandstone Saturated With Carbonated Nacl Solutions At Supercritical Co2 Conditions, Miftah Hidayat, Mohammad Sarmadivaleh, Jos Derksen, David Vega-Maza, Stefan Iglauer, Jan Vinogradov

Research outputs 2022 to 2026

The zeta potential is a measure of electric potential at the mineral-electrolyte interfaces. The zeta potential of natural sandstones depends on mineralogy, electrolyte pH, concentration, composition, amount of dissolved CO2, and temperature. We report for the first time the zeta potential measured on clayey sandstone comprising quartz, kaolinite, illite, albite and microcline saturated with NaCl solutions at supercritical CO2 conditions. Our results demonstrate that zeta potentials in clayey sandstone samples at supercritical CO2 conditions are significantly different from similar measurements conducted under ambient conditions and from those obtained with clean sandstones. Supercritical CO2 zeta potential remains negative but is influenced …

Psycholinguistic Profiling Of Children With Sluggish Cognitive Tempo, Kirsten M. Russell, Sean M. Redmond, Andrea C. Ash

Faculty Publications

Language disorders are frequently comorbid with attention deficit/hyperactivity disorder (ADHD). Sluggish cognitive tempo (SCT),a second attention disorder, may potentially explain some of the links between language disorders and ADHD. In this study we examined the psycholinguistic abilities of 207 children (mean age 7;10) with and without clinically significant levels of SCT symptoms to determine the degree to which symptoms of language disorder co-occur in cases of SCT. Analyses of children’s tense-marking, nonword repetition, and sentence recall indicated that deficits in these areas were not associated with SCT. Instead, SCT appears to be more closely aligned with features of social (pragmatic) …

Representation Of Race And Ethnicity In Counseling And Counseling Psychology Journals, Jared M. Hawkins, Roy A. Bean, Timothy B. Smith, Jonathan G. Sandberg

Faculty Publications

Whereas previous literature reviews have concluded that people of color are underrepresented in psychological literature, the fields of counseling and counseling psychology have taken a clear affirmative stance with respect to human diversity. This study sought to evaluate the representation of people of color in four key journals across the 2000-2019 timespan: The Counseling Psychologist, Journal of Counseling Psychology, Journal of Counseling & Development, and Counselling Psychology Quarterly. Journal articles were coded for several variables, including focus on racial/ethnic minority (REM) groups and article content topics. Results indicated that 757 (26.3%) of the articles were coded REM-focused. Of …

Multidimensional Signals And Analytic Flexibility: Estimating Degrees Of Freedom In Human-Speech Analyses, Stefano Coretta, Joseph V. Casillas, Joseph A. Stanley, Timo B. Roettger

Faculty Publications

Recent empirical studies have highlighted the large degree of analytic flexibility in data analysis that can lead to substantially different conclusions based on the same data set. Thus, researchers have expressed their concerns that these researcher degrees of freedom might facilitate bias and can lead to claims that do not stand the test of time. Even greater flexibility is to be expected in fields in which the primary data lend themselves to a variety of possible operationalizations. The multidimensional, temporally extended nature of speech constitutes an ideal testing ground for assessing the variability in analytic approaches, which derives not only …

Order Of Operations In Sociophonetic Analysis, Joseph A. Stanley

Faculty Publications

In modern sociophonetic data analysis, a researcher makes numerous decisions when processing their data. Many of the “big” decisions include how data is collected, how audio is transcribed, how these transcriptions are aligned to the audio, and how acoustic measurements are extracted. Once a spreadsheet of numbers has been generated, further decisions must be made regarding normalization, detecting and handling outliers, and excluding tokens irrelevant to the research question. This paper takes a closer look at this second group of decisions—those made after acoustic measurements have been extracted—and shows that the order in which they are applied can have significant …

How Sample Size Impacts Pillai Scores: And What Sociophoneticians Should Do About It, Joseph A. Stanley, Betsy Sneller

Faculty Publications

Pillai scores in Sociolinguistics

• A way to quantify overlap in multiple dimensions (e.g., F1, F2, duration) (Hay et al., 2006; Nycz & Hall-Lew 2013)
• Some concern about unequal vowel categories sizes (Johnson 2015; convo on Twitter June 2, 2021)
• Our solution: a big simulation to show exactly what impact sample size has on Pillai scores

The Simulation

1. Start with a single bivariate normal distribution.

2. Sample two “vowel classes” from this distribution. – Ground Truth is they’re merged.

3. Calculate the Pillai score – Should be close to 0 because they’re merged!

4. Repeat many, many times.

Generational Change In Formant Trajectories: The Low-Back-Merger Shift In Longview, Washington, Joseph A. Stanley

Faculty Publications

How have vowel formant trajectories changed as part of the LBMS?

As the front lax vowels lower and centralize, their formant dynamics change

• Specifically, F2 is less dynamic, resulting in a “bounce” shape in F1-F2 plots.
• More evident for lower vowels than higher ones.

Formant dynamics may change as global position changes (but not always).

• Especially true with BAT and BET here.
• BIT mostly unclear.
• BAN did not have substantial changes in vowel dynamics.

Vowels Can Merge Because Of Changes In Trajectory: Prelaterals In Rural Utah English, Joseph A. Stanley, Lisa Morgan Johnson

Faculty Publications

Overview

• Front vowels: tense-lax pairs getting closer in apparent time.
• Back vowels: three-way convergence of WOLF, JOLT, and MULCH.
• This data suggests a merger by approximation.

Expanding to trajectories gives greater insight into this type of merger.

• Kinda like a zipper.

Greater detail in this merger by approximation.

• The nuclei don’t appear to trigger the shift
• The lateral gradually increases its influence, and the nucleus follows.

Trajectories are potentially important for discovering how vowels shift.

• More recent techniques can allow us to answer these questions.

Homogeneity And Heterogeneity In Western American English, Joseph A. Stanley, Jessica Sheperd, Auna Nygaard

The Low-Back-Merger Shift (Becker 2019)

Description:

• BAT, BET, BIT lower and retract
• Arguably a chain shift
• Triggered by BOT-retraction
• Typically BAT shifts the most
• BET and especially BIT less shifted

Previous accounts are based on isolated, independent studies.

“Clearly, collecting the same type of data from all sites would be optimal in allowing us the most reliable cross-region assessment.” (Fridland et al. 2017:172)

This study is a direct response to that call.

The Role Of Emotions As Mechanisms Of Mid-Test Warning Messages During Personality Testing: A Field Experiment, Hairong Li, Jinyan Fan, Guoxiang Zhao, Minghui Wang, Lu Zheng, Hui Meng, Qingxiong Weng, Yanping Liu, Filip Lievens

Research Collection Lee Kong Chian School Of Business

This study focuses on the role of emotions in personnel selection and faking research. In particular, we posit that emotions are likely to be activated when applicants receive warning messages from organizations. Drawing on Nabi (Nabi, Communication Theory, 9, 1999, 292) cognitive-functional model of discrete negative emotions, we propose and empirically test the effects of three discrete negative emotions (guilt, fear, and anger) triggered by a warning message during a personality test on personality score accuracy and perceived test fairness. Participants in this within-subjects field experiment were 1,447 applicants for graduate school at a large public university in China. They …

Temporal Fluency And Floor/Ceiling Scoring Of Intermediate And Advanced Speech On The Actfl Spanish Oral Proficiency Interview–Computer, Troy L. Cox, Alan V. Brown, Gregory L. Thompson

Faculty Publications

The rating of proficiency tests that use the Inter-agency Roundtable (ILR) and American Council on the Teaching of Foreign Languages (ACTFL) guidelines claims that each major level is based on hierarchal linguistic functions that require mastery of multidimensional traits in such a way that each level subsumes the levels beneath it. These characteristics are part of what is commonly referred to as floor and ceiling scoring. In this binary approach to scoring that differentiates between sustained performance and linguistic breakdown, raters evaluate many features including vocabulary use, grammatical accuracy, pronunciation, and pragmatics, yet there has been very little empirical validation …

Remdesivir Analog As Sars-Cov-2 Polymerase Inhibitor: Virtual Screening Of A Database Generated By Scaffold Replacement, Amgad Albohy, Mohamed A. Said, Mohamed A. Abdelrahman, Hany Said

Pharmacy

By the end of 2019, a novel strain of the corona viral family named SARS-CoV-2 emerged in Wuhan, China and started to spread worldwide causing one of the most dangerous lethal pandemics. Researchers utilized various reported inhibitors and drug databases for virtual screening analysis against this novel strain. Later on, they succeeded to fish and repurpose remdesivir, an antiviral nucleotide analogue that inhibits RNA polymerase of the Ebola virus, as a promising candidate against SARS-CoV-2. In this study, we used the interactions of the co-crystallized metabolite of remdesivir with SARS-CoV-2 RdRp isozyme (PDB 7BV2) to design an analog with potential …

Introduction. Acute pain is a prevalent problem for dementia residents in nursing homes. A variety of intervention strategies have been applied to address this problem. However, there remains an issue of inadequate pain control. This study aims to explore the analgesic efficacy of auricular acupressure (AA) for dementia residents with acute pain in nursing homes. Methods. A multicenter, single-blind, randomized, and sham-controlled clinical trial was performed in three nursing homes in Yinchuan, China. All of the 206 eligible patients with acute pain were randomly divided into two groups for real AA therapy or sham AA (at sham point stimulation) therapy. …

The Frequency Of Periodontitis In End‑Stage Renal Disease On Hemodialysis In A Sample Of Egyptian Population: Multi‑Center Clinical Cross‑Sectional Study, Enji Ahmed Mahmoud, Asmaa Abobakr, Eman Khalil, Radwa Raghib

Dentistry

Background: There is a general assumption that periodontal disease is highly prevalent among patients with chronic renal failure undergoing hemodialysis. The aim of the study to estimate the frequency of periodontitis in patients on hemodialysis among a sample of the Egyptian population, as well as the correlation between different clinical parameters of periodontal status with serum creatinine and blood urea. This may rule out the bidirectional relationship between periodontitis and renal failure in patients on hemodialysis. Methods: The study was conducted on 263 hemodialysis patients (165 males and 98 females) at three dialysis centers in Benha Governorate, Egypt (Benha Hospital, …

Schedule Reliability In Liner Shipping Timetable Design: A Convex Programming Approach, Abraham Zhang, Zhichao Zheng, Chung-Piaw Teo

Research Collection Lee Kong Chian School Of Business

Container liner shipping is the primary mode of moving manufactured products across continents. Partly due to inherent uncertainties at sea and ports, the liner shipping industry has long had a notorious reputation of schedule delays and unreliable on-time performance. This paper formulates a new approach to incorporate schedule reliability targets in liner shipping timetable design, to balance bunker consumption, time taken for the voyage, and schedule delays. We first model a surrogate problem using a copositive program through a moment decomposition approach and solve it as a convex semidefinite programming relaxation. We next incorporate schedule reliability targets implicitly by exploiting …

Conditional Relationship Between Distress Risk And Stock Returns, Su Hee Yun, Jung Min Kim

Research Collection Lee Kong Chian School Of Business

Purpose: Previous research on the relationship between a firm’s distress risk and future stock returns produces inconsistent results. This study attempts to explain the conflicting results of earlier studies by showing that systematic distress risk leads to positive rewards, while unsystematic distress risk leads to low stock returns. In addition, this study intends to elucidate the factors of systematic distress risk and unsystematic distress risk, respectively. In this way, this study informs the rational investor what kind of distress risk they should take. Design/methodology/approach: This study considers two distress-predictor sets to show a possibility between distress risk and stock returns …

Social Media Influencers In Crisis: Providing Counsel On Instagram, Pang, A., Debbie Lee, Gindelin Low, Valerie Hum

Research Collection Lee Kong Chian School Of Business

Increasingly, organizations are harnessing social media influencers (SMIs) as third-party advocates or key opinion leaders (KOLs). Consumers view them as knowledgeable sources of information (Tuten & Solomon, 2017). In the United States, the Kardashians are used by a number of organizations to promote their products. Yang (2019) noted that while Western influencers are mostly video bloggers on Instagram or YouTube, Chinese KOLs have multiple channels, including social media platforms WeChat and Weibo, social networking sites Douban or TikTok. Figures from 2016 point to it as a US$8.6 billion industry in China (Yang, 2019).
