Laryngeal Desiccation Challenge And Nebulized Isotonic Saline In Healthy Male Singers And Nonsingers: Effects On Acoustic, Aerodynamic, And Self-Perceived Effort And Dryness Measures, Christopher Dromey, Kristine Tanner, Robert B. Fujiki, Ray M. Merrill, Whitney Robb, Katherine A. Kendall, J Arden Hopkin, Ron W. Channell, M Preeti Sivasankar

Faculty Publications

Summary: Objectives. This study examined the effects of a laryngeal desiccation challenge and nebulized isotonic saline on voice production in young, healthy male singers and nonsingers. Study design. This is a prospective, double-blind, within-subjects experimental design. Methods. Participants included 10 male university-trained singers and 10 age-matched nonsingers (mean age, 21.8 years; range, 18–26 years) who underwent a 30-minute oral breathing laryngeal desiccation challenge using medical grade dry air (<1% relative humidity) on two occasions in consecutive weeks. After the challenge, participants received either 3 mL or 9 mL of nebulized isotonic saline (0.9% Na+ Cl); order of administration was counterbalanced. Phonation threshold pressure (PTP), the cepstral spectral index of dysphonia (CSID) for sustained vowels and connected speech, and self-perceived vocal effort, mouth dryness, and throat dryness were measured at each recording (baseline, after challenge, and at 5, 35, and 65 minutes after treatment). Results. Self-perceived effort and dryness measures increased (worsened) after desiccation challenge and decreased (improved) after nebulized treatment (P < 0.05). No consistent changes were observed for PTP or CSID over time. Overall, singers demonstrated significantly lower vocal effort and CSID as compared with nonsingers. Conclusions. Young, vocally healthy men may not experience physiologic changes in voice production associated with laryngeal desiccation and nebulized saline treatments; however, self-reported increases in vocal effort which are associated with dryness symptoms might improve with nebulized treatments. Future hydration research should consider age and sex variables

The Effects Of Noise On Speech Movements In Young, Middle- Aged, And Older Adults. Speech, Language And Hearing, Christopher Dromey, Sarah Scott

Faculty Publications

People often talk in noisy environments, which can influence the effectiveness of communication. This study examined the impact of several types of noise on speech production by measuring lip movements during a sentence repetition task. Sixty participants in three age groups ranging from 20 to 70 repeated a sentence under five noise conditions (silence, one person reading aloud, two readers, six readers, and pink noise).A head-mounted strain gauge system tracked vertical lip movements. With the presentation of noise during a speaking task, the intensity increased due to the Lombard effect in all of the noise conditions. The utterance duration for …

Absence Of “Joseph Smith” In The Book Of Mormon: Lack Of The Name Letter Effect In Nephite, Lamanite, And Jaredite Names, Bruce L. Brown, Sharon Black, Brad Wilcox, Wendy Baker Smemoe

Faculty Publications

Although some authors of fiction attempt to hide their real names by publishing their work under pseudonyms, the letters and sounds they consciously or subconsciously select for the names of their characters often reveal the author’s true identity. Since 1985, research has explored the name letter effect—the preference people show for the letters and sounds (especially initial sounds) in their own names. This tendency is evident in the highly personal and introspective literature produced in the United States during Joseph Smith’s lifetime by authors such as Nathaniel Hawthorne, Washington Irving, and Edgar Allan Poe. The purpose of this study was …

No Association Between Current Depression And Latent Toxoplasmosis In Adults, Bruce L. Brown, Shawn D. Gale, Andrew N. Berrett, Lance D. Erickson, Dawson W. Hedges

Faculty Publications

Changes in behaviour and cognition have been associated with latent infection from the apicomplexan protozoan Toxoplasma gondii (Nicolle et Manceaux, 1908) in both animal and human studies. Further, neuropsychiatric disorders such as schizophrenia have also been associated with latent toxoplasmosis. Previously, we found no association between T. gondii immunoglobulin G antibody (IgG) seropositivity and depression in human adults between the ages of 20 and 39 years (n = 1 846) in a sample representative of the United States collected by the Centers for Disease Control as part of a National Health and Nutrition Examination Survey (NHANES) from three datasets collected …

Nature Versus Technology: Which Is More Appealing To Youth Ages 11-14?, Micky Lyn Zurcher

Sociology and Anthropology

Recent studies show playtime for youth has shifted from playing outdoors to being connected to a screen-based device. This study examines the amount of time youth ages 11-14 are spending in nature versus the amount of time they are spending connected to a screen-based device. The Drift Prairie group (N=16) spent a day in the great outdoors interacting with their peers and nature. The Comparison group (N=19) was randomly selected from a local 4-H organization. Both the Drift Prairie group and the Comparison group were surveyed using a questionnaire. The Drift Prairie group response was 62.6% active in nature whereas …

An Organizational Assessment For The Boys & Girls Clubs Of South Park Using Community Capital Frameworks, April-Dawn Knudsen

Sociology and Anthropology

The Boys & Girls Clubs of South Park (BGCSP) is a youth service 501(c)3 serving Park County, Colorado. With over 60% of Park County’s workforce commuting to another county for employment the need for affordable out-of-school youth care is apparent, but the need for BGCSP goes further. These rural communities need local opportunities for children. This isolated population is a food desert, medical desert, and had limited industry. The schools lack resources and the population is projected to see unprecedented growth over the next eight years. The need for BGCSP is apparent, but what is their impact? The following chapters …

Brine-Contaminated Soils In Western North Dakota: Site Assessment Methodology And A New In-Situ Remediation Method, Aaron Wallace Klaustermeier

Soil Science

Anthropogenic soil salinity caused by produced water (i.e., brine) contamination is an issue in all oil and gas producing regions. The objectives of this research are to develop soil electrical conductivity (EC) conversion equations for rapid site assessment of brine spills and to determine the efficacy of crystallization inhibitors as an in-situ remediation method. Conversion equations were developed for soil-to-water suspensions and saturated paste extracts (ECe) on brine-contaminated soils. These new equations provided the best prediction of ECe when compared to 14 other equations reported in the literature. A crystallization inhibitor (C18Fe7N18) applied to NaCl-contaminated soils using various concentrations and …

Criteria Language Teachers Use When Selecting Call Technologies, K. James Hartshorn, Benjamin L. Mcmurry, Peter J. Rich, Neil J. Anderson, David D. Williams

Faculty Publications

It is important to identify the criteria that language teachers consider when selecting technologies. Software designers and developers, program administrators, and others need to be aware of adoption issues and practices for CALL technology. The focus of this case study was to look at six language instructors considered to be experts in their use of technology in the classroom and examine the criteria they use when selecting CALL resources or activities in the classroom. Interviews, recorded classroom observations, and analyses of teaching materials resulted in three themes: consideration of pedagogy, consideration of convenience, and consideration of authenticity. These are discussed …

An Ewp Model Of Quechua Agreement: Further Evidence Against Dm, Joseph A. Stanley

Faculty Publications

In this paper we first describe the Quechua verbal agreement paradigm using two generative morphological theories and then argue that Anderson’s EWP accounts for the data better than Distributed Morphology (DM). Kerke (1996) has already shown evidence against DM using this paradigm, and we provide additional support for this.

The Quechua verbs conjugate to agree with the subject and the object of the VP in one of three tenses (Table 1). Each cell contains up to five morphemes, from a selection of twelve, which appear consistently in the same order. Though there is some semblance of regularity in the paradigm, …

Phonetic Shift /Ɔr/ Phonemic Change? American English Mergers Over 40 Years, Joseph A. Stanley, Margaret E. L. Renwick

Faculty Publications

In this paper we analyze the vowel formants of a speaker over four decades to show phonemic change through time. Other real-time studies (Harrington, Palethorpe & Watson 2000; Harrington & Reubold 2015) have found that the vowel spaces of UK English speakers shift over the lifetime, likely as a consequence of interaction with speakers of other dialects or social classes. We focus on an understudied variety of English, spoken in the western United States, to investigate a pair of phonological mergers, the cord-card merger and the hoarse-horse merger.

The cord-card merger is a result of a historical three-way contrast of …

Teacher And Student Perspectives On Facilitating A Sense Of Community Through An Online High School’S “Shepherding” Program, Jeffery Drysdale, Charles R. Graham, Jered Borup

Faculty Publications

Student disconnectedness remains a serious concern in K-12 online learning—especially in programs where students take most or all of their coursework online. In this research we examined a “shepherding program” designed to encourage a sense of community among teachers and students at an online charter school. Every online teacher served as a “shepherd” for 20 to 25 students and worked to establish close relationships with each student. Data was collected through 5 teacher focus groups, 5 one-on-one teacher interviews, and 10 one-on-one student interviews. A qualitative analysis using Rovai’s sense of community framework examined how the shepherding program influenced shepherd-student …

A Qualitative Analysis Of Institutional Drivers And Barriers To Blended Learning Adoption In Higher Education, Wendy W. Porter, Charles R. Graham, Robert G. Bodily, Daniel S. Sandberg

Faculty Publications

The authors previously proposed a framework for institutional BL adoption (Graham, Woodfield, & Harrison, 2012), identifying three stages: (a) awareness/exploration, (b) adoption/early implementation, and (c) mature implementation/growth. The framework also identified key strategy, structure, and support issues universities may address at each stage. In this paper, the authors applied that framework as well as Rogers' (2003) diffusion of innovations theory to determine the degree to which institutional strategy, structure, and support measures facilitate or impede BL adoption among higher education faculty. In addition, the authors explored whether higher education faculty's innovation adoption category affects which measures facilitate or impede BL …

Online Student Perceptions Of The Need For A Proximate Community Of Engagement At An Independent Study Program, Darin R. Oviatt, Charles R. Graham, Jered Borup, Randall S. Davies

Faculty Publications

Research suggests that collaborative learning designs, which require interaction with teachers and peers, can promote engagement and learning for online courses. Many K-12 students seek supplemental online courses to meet graduation requirements and desire flexibility, which often conflicts with required interactions. This paper asserts that online independent study learners may create a proximate community of engagement (PCE) to provide the benefits of collaboration and interactions. Using the adolescent community of engagement (ACE) framework as a lens for identifying interactions, this study surveyed K-12 independent study students to assess their perception of the need for interaction with a support community while …

Understanding Audit Quality: Insights From Audit Professionals And Investors*, Brant E. Christensen, Steven M. Glover, Thomas C. Omer, Marjorie K. Shelley

Faculty Publications

Projects seeking to define, measure, and evaluate audit quality are on the agendas of auditing standards setters as well as audit firms. The Public Company Accounting Oversight Board (PCAOB) currently provides information regarding audit quality through the release of inspection reports, and the Board intends to establish and report audit quality indicators. To provide additional perspective on audit quality, we obtain auditors’ and investors’ views, definitions, and indicators of audit quality. We find that investors’ definitions of audit quality focus more on inputs to the audit process than do auditors’, and that investors view the number of PCAOB deficiencies as …

Applying Basic Gamification Techniques To It Compliance Training: Evidence From The Lab And Field, Ryan J. Baxter, D. Kip Holderness, David A. Wood

Faculty Publications

Companies depend on strong internal controls to protect the integrity of accounting information systems. IT security and data privacy training are critical controls to safeguarding company information. However, employees often dislike the training, which can cause a lack of attention to and poor understanding of training concepts, leading to less effective internal controls. To improve the training experience, companies are implementing principles of games into employee training modules; a practice known as gamification. Using a laboratory experiment of data privacy training and a field study involving a publicly-traded bank’s rollout of IT security training, we test whether a training environment …

Comparing The Publication Process In Accounting, Economics, Finance, Management, Marketing, Psychology, And The Natural Sciences, David A. Wood

I present two types of data about the publication and review process in the accounting, economics, finance, management, marketing, psychology, and natural science disciplines. First, I collect all articles published in 2012 in top tier journals of these disciplines and compare the articles based on word counts, figures and tables included in each article, the time it took to be published, citations, the number of co-authors, and submission fees. I then survey academics in each discipline. Survey questions were designed to evaluate overall perceptions of the review process; changes in the review process in the last 5 years; opinions about …

Do Managers Really Guide Through The Fog? On The Challenges In Assessing The Causes Of Voluntary Disclosure, Travis Dyer, Mark Lang, Lorien Stice-Lawrence

Faculty Publications

Guay e tal. (2016) document that firms with longer and more complex 10-Ks provide  relatively more voluntary disclosure, which they interpret as evidence that managers use voluntary disclosure to mitigate negative effects of complex mandatory disclosure. We review the results of Guay et al. and focus on two main challenges to inferring causality: (1) the coincidence of upward over-time trends in annual report length, complexity, and voluntary disclosure, and (2) the potential for omitted correlated variables, such as changes in firm economics, to drive changes in 10-K textual characteristics and voluntary disclosure. While the results in Guay et al. are …

Using Unstructured And Qualitative Disclosures To Explain Accruals, Richard Frankel, Jared Jennings, Joshua A. Lee

Faculty Publications

We examine the usefulness of support vector regressions (SVRs) in assessing the content of unstructured, qualitative disclosures by relating MD&A-based SVR-accrual estimates (MD&Aaccruals) to actual accruals. We find that MD&A accruals explain a statistically and economically significant portion of firm-level accruals and identify more persistent accruals. We find that the explanatory power of MD&A accruals is higher for more readable 10Ks, thereby providing evidence for the construct validity of the readability measures. To highlight the flexibility of the SVR method, we apply it to other dependent variables and disclosures. We find that MD&A-based cash-flow forecasts produced by SVR predict next …

Adolescent Summer Camp Volunteers’Attitudes Toward Peers With Disabilities, Megan Fort, Neil Lundberg, Ramon Zabriskie, Dennis Eggett, Mary Anne Prater, Keith Barney

Faculty Publications

This study explored themalleability of adolescent attitudes toward their peers with disabilities after volunteering in a summer day-camp. The Contact with Disabled Persons Scale (CDP) and the Multi-Dimensional Attitude Scale (MAS) were used to collect data in order to determine the association between volunteering in a recreation-based summer day camp and adolescent attitudes toward disability. After a covariateadjusted regression analysis, contact with individuals with disabilities was found to significantly predict change in attitudes toward disability. Dyadic interviews were held after camp participation to provide additional sources of data with potential for deeper understanding of the camp experience for volunteers. The …

Female Veterans’ Involvement In Outdoor Sports And Recreation, Neil Lundberg, Stacy Taniguchi, Rachel Mcgovern, Shauna Smith

Faculty Publications

Previous research has recognized the need to better understand the experience of female veterans and their adjustment upon returning home, especially considering that a growing number of veterans are women. Their stories, particularly as they relate to combat and the associated wounds of war, largely remain untold. Therefore, the purpose of this project was to employ a theoretical sample from Grounded Theory methodology to determine if similar recreation opportunity structure patterns existed in the use of outdoor sports and recreation for a sample of female veterans, as had been found in previous research with individuals with physical disabilities. The investigation …

Vaccination Rates Are Associated With Functional Proximity But Not Base Proximity Of Vaccination Clinics, John Beshears, James J. Choi, David I. Laibson, Brigitte C. Madrian, Gwendolyn I. Reynolds

Faculty Publications

Background: Routine annual influenza vaccinations are recommended for persons 6 months of age and older, but less than half of US adults get vaccinated. Many employers offer employees free influenza vaccinations at workplace clinics, but even then take-up is low.

Objective: To determine whether employees are significantly more likely to get vaccinated if they have a higher probability of walking by the clinic for reasons other than vaccination.

Method: We obtained data from an employer with a free workplace influenza vaccination clinic. Using each employee’s building entry/ exit swipe card data, we test whether functional proximity—the likelihood that the employee …

Who Is Easier To Nudge?, John Beshears, James J. Choi, David Laibson, Brigitte C. Madrian, Sean (Xixiang) Wang

Faculty Publications

Identifying who is more influenced by a default is challenging, since individuals may be more likely to remain at the default either because they are more susceptible to defaults in general or because the default is closer to their preferred choice. We apply a statistical model to ten large companies’ 401(k) plans to distinguish between these two channels. Even after controlling for contribution rate preferences, low-income and young individuals are slower to opt out of contribution rate defaults. The evidence is consistent with the default changing contribution rate preferences, as predicted by anchoring or endorsement effects, and there is weaker …

Your Memory Is Working Against You: How Eye Tracking And Memory Explain Habituation To Security Warnings, Bonnie Anderson, Jeffrey L. Jenkins, Anthony Vance, C. Brock Kirwan, David Eargle

Faculty Publications

Securitywarnings are critical to the security of end users and their organizations, often representing the final defense against an attack. Because warnings require users to make a contextual judgment, it is critical that they pay close attention to warnings. However, research shows that users routinely disregard them. A major factor contributing to the ineffectiveness of warnings is habituation, the decreased response to a repeated warning. Although previous research has identified the problem of habituation, the phenomenon has only been observed indirectly through behavioral measures. Therefore, it is unclear how habituation develops in the brain in response to security warnings, and …
