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 …

Blended Learning Citation Patterns And Publication Networks Across Seven Worldwide Regions, Kristian J. Spring, Charles R. Graham

Faculty Publications

The field of international blended learning (BL) is primed to benefit from stronger communication and collaboration. Collaboration is currently limited, and regions vary greatly in terms of citations. However, BL is growing worldwide and each region is an important part of the community. The goal of this research is to explore where the most impactful conversations about BL worldwide are occurring and how, if at all, are they connected to one another in terms of citations and publications. We present here the most cited BL articles from each region, the journals that publish these articles, and citation and publication patterns …

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 …

How Inflection Class Systems Work: On The Informativity Of Implicative Structure, Jeffery R. Parker, Andrea D. Sims

Faculty Publications

The complexity of an inflection system can be defined as the average extent to which elements in the system inhibit motivated inferences about the realization of lexemes’ paradigm cells. Research shows that systems tend to exhibit relatively low complexity in this sense. However, relatively little work has explored how structural and distributional aspects of the inflectional system produce this outcome. In this paper we use the tools of information theory to do so. We explore a set of nine languages that have robust inflection class systems: Palantla Chinantec, French, Modern Greek, Icelandic, Kadiwéu, Nuer, Russian, Seri, and Võro. The data …

Comparing The Academic Word List With The Academic Vocabulary List: Analyses Of Frequency And Performance Of English Language Learners, K. James Hartshorn, Judson M. Hart

Faculty Publications

Although use of the Academic Word List (AWL) has been successful and extensive in English as a second language (ESL) materials development and pedagogy (Coxhead 2000, 2011), some scholars have raised concerns about possible flaws. In an effort to overcome limitations, Gardner and Davies (2014) have presented a "new Academic Vocabulary List" (AVL). While their description suggests a number of potential advantages of the AVL over the AWL, these lists have yet to undergo ecologically valid comparisons based on actual ESL learner performance. Thus, this study compares the AWL with the AVL in an effort to identify some of the …

Local Corticotropin Releasing Hormone (Crh) Signals To Its Receptor Crhr1 During Postnatal Development Of The Mouse Olfactory Bulb, Joshua Ortiz-Guzman, Longwen Huang, Alexander M Herman, Lesley Chaboub, Benjamin Deneen, Nicholas J Justice, Benjamin R Arenkiel

Faculty, Staff and Students Publications

Neuropeptides play important physiological functions during distinct behaviors such as arousal, learning, memory, and reproduction. However, the role of local, extrahypothalamic neuropeptide signaling in shaping synapse formation and neuronal plasticity in the brain is not well understood. Here, we characterize the spatiotemporal expression profile of the neuropeptide corticotropin-releasing hormone (CRH) and its receptor CRHR1 in the mouse OB throughout development. We found that CRH-expressing interneurons are present in the external plexiform layer, that its cognate receptor is expressed by granule cells, and show that both CRH and CRHR1 expression enriches in the postnatal period when olfaction becomes important towards olfactory-related …

Continuation Of A Life Worth Living: Empathetic Design For The Alzheimer’S Community, Leslie Hulbert

Architecture Theses and Projects

This thesis’ mission is to create a comfortable environment for those suffering with Alzheimer’s and dementia. The institutional environments of the past are not sufficient for such individuals and their families. A community atmosphere is what they need; an entire complex just for them. The victims of this terrible memory defeating disease just want to go home. For many, this is not possible, therefore they should be given an environment that reminds them of home. They should have their own space that is customizable and warm. They should also be free to wander at their leisure. Their freedom should not …

The Ph.D. Rises In American Law Schools, 1960-2011: What Does It Mean For Legal Education?, Justin Mccrary, Joy Milligan, James Cleith Phillips

Faculty Scholarship

At a time when some perceive law schools to be in crisis and the future of legal education is being debated, the structural shift toward law professors with Ph.Ds is an important, under-examined trend. In this article, we use an original dataset to analyze law school Ph.D hiring trends and consider their potential consequences. Over the last fifty years the proportion of law professors with Ph.Ds has risen dramatically. Over a third of new professors hired at elite law schools in recent years come with doctoral degrees in fields outside the law. We use our data to consider the scope, …

Custom's Method And Process: Lessons From Humanitarian Law, Monica Hakimi

Faculty Scholarship

A central question in the literature on customary international law (CIL) goes to method: what is the proper method for “finding” CIL – that is, for determining that particular norms qualify as CIL? The traditional method is to identify a widespread state practice, plus evidence that states believe that the practice reflects the law (opinio juris). That method has long been criticized as incoherent, unworkable, and out of touch with modern sensibilities. Thus, much of the CIL literature addresses its perceived problems. The principal goals of this literature are to help resolve whether norms that are claimed to …

Soes And State Governance: How State-Owned Enterprises Influence China's Legal System, Zheng Lei, Benjamin L. Liebman, Curtis J. Milhaupt

Faculty Scholarship

Most of the existing literature on Chinese SOEs asks how state ownership affects their governance. This chapter turns the question on its head: How do SOEs affect state governance in China? The chapter begins by distinguishing different modes of interaction between the Party-state and SOEs. Focusing on these modes of interaction, the chapter analyzes how SOEs have influenced China’s legal system. This chapter discusses the ideological and positional advantages enjoyed by SOEs in their legal treatment, and provide an analysis of SOEs’ impact on legislation, administrative rulemaking and in particular, the courts. It concludes by exploring a key implication of …

Institutional Versus Intermediated Buyers: Barriers And Requirements Of Buying Local Food Products, Jennifer Marie Moldovan

Graduate Theses/Dissertations

Expenditures on locally grown food products are only a small portion of the total food expenditures in the United States. In order to find a way to increase this percentage, this study aims to identify various types of buyers currently participating in the purchase of locally grown food products. Buyers were divided into two groups: institutions and intermediated. A comparison of for both classifications of buyers was done to find the difference in their perceived barriers and requirements for purchasing local food. Determining these differences could help in future policymaking decisions in local food industries. This will also help farmers …

Voluntary participants were school administrators, general and special education teachers, instructional coaches, and guidance …

Sanctified By God's Word: Towards A Websterian Ontology Of Scripture And Church, Benjamin J. Lappenga

Faculty Work Comprehensive List

John Webster’s account of Scripture grants the canonical texts an ontology determined by their divine use, discusses Scripture as an aspect of the doctrine of revelation rather than the church, and above all preserves the capacity of God’s Word to question and form believers. Yet, Webster’s proposal has met resistance from theologians who find his accent on sola scriptura inconsistent with his claim that interpretation (not simply “text”) has ontological force as a part of “sanctification.” This paper asks whether it is possible to retain a robustly Websterian account of Scripture while at the same time denying that Scripture’s primacy …

Complex System Governance For Acquisition, Joseph Bradley, Polinpapilinho Katina, Charles Keating

Engineering Management & Systems Engineering Faculty Publications

As acquisition processes have become more complex, they appear to no longer be governable by traditional approaches. Missed budgets, delayed deliveries, and expensive canceled systems appear to becoming more prevalent. Numerous investigations have been conducted attempting to elicit the factors that prevented success. Those systems that succeed in terms of usability, budget, and delivery schedule are the rarity and often become case studies themselves as we try to extract the characteristics that differentiate success from failure. A different viewpoint is to look at the acquisition system from the perspective of Complex Systems Governance (CSG). Recent developments in the field of …

Chair Support, Faculty Entrepreneurship, And The Teaching Of Statistical Reasoning To Journalism Undergraduates In The United States, Robert J. Griffin, Sharon Dunwoody

College of Communication Faculty Research and Publications

Statistical reasoning is not the same as doing calculations. Instead, it involves cognitive skills such as the ability to think critically and systematically with data, skills important for everyday news work and essential for the era of data journalism. Twin surveys of the chairs of undergraduate journalism programs in the United States, conducted 11 years apart, revealed that those who perceived benefits from statistical reasoning instruction were more likely to reward entrepreneurship (faculty attempts to integrate this instruction into their classes), but with slow gains over time in the fairly small number of such faculty. Being consistent with university goals …

Farmed And Dangerous? A Case Study Of Chipotle’S Branded Entertainment Series And Polarized Reactions To Its Satirical Depiction Of Farming And Agribusiness, Nathan Gilkerson, Rebecca Swenson, Betsy Anderson

College of Communication Faculty Research and Publications

This study follows Chipotle’s innovative strategy of using branded entertainment and satire to enhance its brand image and positive consumer perceptions, while negatively portraying an entire industry. The study explores audience reactions to Chipotle’s satirical Farmed and Dangerous program, part of the company’s broader “Food with Integrity” campaign. Increasing agricultural literacy and understanding among the general public is a priority (Doerfert, 2011). Yet marketing communication campaigns—and responses or reactions to those campaigns—that simplify issues into distinct “sides,” or focus on attacks, prevent deep discussion of the complexity of our food system and efforts to collaborate on solutions. Research presented uses …

Defining A Medium: The Educational Aspirations For Early Radio, Amanda R. Keeler

College of Communication Faculty Research and Publications

This essay examines the attempts by many writers to steer the burgeoning U.S. radio industry towards educational uses and programming in the 1920s. At the same time that commercial radio began to take shape, several competing and seemingly incompatible visions of the airwaves emerged—one of which privileged the use of radio for educational purposes. Using discourse from trade journals, general interest magazines, and newspapers, this article explores the calls for educational programming amid the rapidly expanding and consolidating commercial radio industry.

Sound Recognition Of Historical Visibility: The Radio Preservation Task Force Of The Library Of Congress: Introduction, Josh Shepperd, Amanda R. Keeler, Chris Sterling

College of Communication Faculty Research and Publications

This issue of Journal of Radio & Audio Media serves as a gesture toward increasing attention to many untold cultural sound histories. The “question” of radio preservation, we’re just coming to realize, closely equates to our responsibility to identify gaps within our historical record, as those gaps are delineated along race, class, orientation, and gendered lines. Sound preservation turns out to be one strategy for how to reconcile failures of recognition. It’s widely accepted that a historian must not project a different meaning upon historical materials than its author intended. Yet at the same time historians might now play the …

Old New Media: Closed-Circuit Television And The Classroom, Amanda R. Keeler

College of Communication Faculty Research and Publications

This article explores closed-circuit television (CCTV) and its ‘bright promise stage’, as it was contemplated, marketed, and implemented as a low-cost classroom tool. After the Federal Communications Commission issued the 1952 Sixth Report and Order, many schools and communities sought to bring educational television to the classroom. However, this model was financially out of reach for most. CCTV was a more affordable version of educational television that could cater to specific classroom needs and allow schools to create their own in-house network. CCTV represents just one of many new technologies that have been promoted as ideal for classroom instruction over …

Community College Faculty Members’ Perceptions Of Creating Digital Content To Enhance Online Instructor Social Presence, Karen M. Arlien

Theses and Dissertations

Current technologies, specifically asynchronous video, allow instructors to enhance their online instructor social presence (OISP) by creating digital content in which they can simultaneously convey their unique persona verbally and nonverbally while supplementing course content. A strong OISP has been shown to contribute toward students’ successful course completion, which continues to be an issue at community colleges. Existing research on the use of digital content to enhance OISP, however, has primarily focused on students’ perceptions even though faculty members are responsible for establishing OISP. The purpose of this study was to ascertain community college faculty members’ perceptions of creating asynchronous …

The Relationship Between Athletes' Perceptions Of Coaching Efficacy And Collective Efficacy In Collegiate Soccer, Frazer Atkinson

Theses and Dissertations

This study examined the relationship between athletes’ perceptions of their coaches’ confidence and team confidence in a sample of 272 collegiate soccer players (M = 19.84 years; SD = 1.42) from the NCAA and NAIA. Athletes’ perceptions of their coaches’ confidence were assessed using a modified version of the Coaching Efficacy Scale (CES) (Feltz, Chase, Moritz & Sullivan, 1999), and a single item measure asked participants to rate their perceptions of their coaches’ confidence. Team confidence was assessed using the Collective Efficacy Questionnaire for Sport (CEQS) (Short, Sullivan & Feltz, 2005). Athletes also reported the results of their team’s previous …
