Frequency Response Of Synthetic Vocal Fold Models With Linear And Nonlinear Material Properties, Stephanie M. Shaw, Scott L. Thomson, Christopher Dromey, Simeon Smith

Faculty Publications

Purpose: The purpose of this study was to create synthetic vocal fold models with nonlinear stress-strain properties and to investigate the effect of linear versus nonlinear material properties on fundamental frequency during anterior-posterior stretching.
Method: Three materially linear and three materially nonlinear models were created and stretched up to 10 mm in 1 mm increments. Phonation onset pressure (P_on), fundamental frequency (F₀) at P_on, and F₀ at 0.20 kPa above P_on were recorded for each length. Measurements were repeated as the models were relaxed in 1 mm increments back to their resting …

Chasing The Double-Bottom Line: Fair Trade And The Elusive Win–Win, Curtis Child

Faculty Publications

Social enterprises embody a problematic proposition. They are premised on the idea that it is possible to create simultaneously social and economic value in a direct, explicit way, yet it would seem that each of these goals is in some amount in consequential tension with the other. The argument of social enterprise is nevertheless that one outcome – financial or social returns – need not be seen as the eventual by-product of focusing on the other, but rather that both can be productively pursued in an immediate sense. Scholars have only started to examine in detail how social enterprises accomplish …

A Proposal For A Feasible, First-Step, Legislative Agenda For Divorce Reform, Alan J. Hawkins

Faculty Publications

American sociologist Andrew Cherlin argues that the institutional boundaries of marriage have shrunk; marriage no longer effectively governs intimate associations before marriage, or structures "proper" pathways to the desired goal of healthy, stable marriage. Personal development and individual emotions are at the core of modern marriage, rather than societal expectations and religious and civil norms. Accordingly, marriages are held together now by internal, psychological forces rather than external, societal forces, and these bonds are substantially weaker. As a result, divorce is common, with about half ending within twenty years; second marriages have even higher rates of disruption. While the divorce …

Workforce Skill Development In Camps, Mat Duerden

Faculty Publications

For many young people, serving as a summer camp staff member can be an entry point into the labor market as well as a valuable job skill-building experience. These camp staff jobs can vary widely by title and expectations but often have one thing in common- the young staff member is often responsible for the safety and well-being of younger children often in their care 24 hours a day for weeks at a time. At a time when employers express concern regarding the workplace readiness of the emerging workforce (Jackson, 2010), camp-based employment, which includes a wide range of positions …

Measuring Life Skills: Standardizing The Assessment Of Youth Development Indicators, Mat D. Duerden, Peter A. Witt, Mariela Fernandez, Marie Jolliff Bryant, Daniel Theriault

Faculty Publications

While the development of life skills (e.g., communication, problem solving, etc.) is a commonly targeted youth program outcome, the lack of standardized conceptualizations and instrumentation make it difficult to compare impacts across programs and develop validated best practices. In order to promote a more unified approach to life skill development, literature reviews were conducted for 10 life skill domains to identify common definitions and, if available, appropriate outcome measures. Data were then collected from an ethnically diverse sample (N = 758) of elementary, middle, and high school aged youth for the 10 identified instruments. Analyses were conducted to ascertain the …

“He’S A Real Dude”: Tributes To Tom Jones, Paul C. Godfrey, Bradley R. Agle

Faculty Publications

Researchers often fail to honor luminaries in their fields of inquiry, at least while they are still alive. What follows is one such tribute, to Dr. Thomas M. Jones, the Boeing Company endowed professor in business management at the University of Washington’s Foster School of Business. Business & Society represents an appropriate outlet for this tribute, given that Tom was the first editor of the journal when the International Association for Business and Society (IABS) assumed editorial control of the Sage Publications journal in 1993.

Using Automatic Speech Recognition Technology With Elicited Oral Response Testing, Troy L. Cox, Randall S. Davies

Faculty Publications

This study examined the use of automatic speech recognition (ASR) scored elicited oral response (EOR) tests to assess the speaking ability of English language learners. It also examined the relationship between ASR-scored EOR and other language proficiency measures and the ability of the ASR to rate speakers without bias to gender or native language. To that end, 179 subjects were given an ASR-scored EOR test with 60 items, followed by an oral proficiency interview (OPI) type assessment and a battery of other language tests. Findings suggest that ASR-scored EOR results could be used alone to predict speaking ability in specific …

Faculty Publications

Monitoring of fatigue cracking in steel bridges is of high interest to many bridge owners and agencies. Due to the variety of deterioration sources and locations of bridge defects, there is currently no single method that can detect and address the potential sources globally. In this paper, we presented a dual mode sensing methodology integrating acoustic emission and ultrasonic wave inspection based on the use of low-profile piezoelectric wafer active sensors (PWAS). After introducing the research background and piezoelectric sensing principles, PWAS crack detection in passive acoustic emission mode is first presented. Their acoustic emission detection capability has been validated …

Piezoelectric Wafer Active Sensors In Lamb Wave-Based Structural Health Monitoring, Lingyu Yu, Victor Giurgiutiu

Faculty Publications

Recent advancements in sensors and information technologies have resulted in new methods for structural health monitoring (SHM) of the performance and deterioration of structures. The enabling element is the piezoelectric wafer active sensor (PWAS). This paper presents an introduction to PWAS transducers and their applications in Lamb wave-based SHM. We begin by reviewing the fundamentals of piezoelectric intelligent materials. Then, the mechanism of using PWAS transducers as Lamb wave transmitters and receivers is presented. PWAS interact with the host structure through the shear-lag model. Lamb wave mode tuning can be achieved by judicious combination of PWAS dimensions, frequency value, and …

Has The Regulation Of Pro Forma Reporting In The Us Changed Investors’ Perceptions Of Pro Forma Earnings Disclosures?, Dirk E. Black, Ervin L. Black, Theodore E. Christensen, William G. Heninger

Faculty Publications

We explore whether investors’ perceptions of pro forma earnings numbers have changed following the regulation of pro forma reporting imposed by the Sarbanes-Oxley Act of 2002 (SOX). First, we find that investors appear to pay more attention to pro forma earnings disclosures in the post-SOX period, consistent with the notion that they perceive that regulation generally renders these disclosures more credible. Second, the results indicate that investors discount aggressive pro forma earnings reports in both periods. However, they appear to discount at least some potentially misleading pro forma earnings disclosures more in the post- SOX period. Finally, our results imply …

Social Relationships And Mortality, Julianne Holt-Lunstad, Timothy B. Smith

Faculty Publications

Social relationships benefit not only mental health but also physical health. This review addresses the following questions: (1) What is the overall magnitude of the effect of social relationships on risk for premature death? (2) How generalized is the effect and are there factors known to influence this association? (3) What are the likely pathways by which social relationships influence longevity? The article concludes by discussing the implications of these findings for potential interventions aimed at reducing risk for mortality.

Transcriptomic Profiles Of Peripheral White Blood Cells In Type Ii Diabetes And Racial Differences In Expression Profiles, Jinghe Mao, Junmei Ai, Xinchun Zhou, Ming Shenwu, Manuel Ong Jr., Marketta Blue, Jasmine T. Washington, Xiaonan Wang, Youping Deng

Faculty Publications

Background: Along with obesity, physical inactivity, and family history of metabolic disorders, African American ethnicity is a risk factor for type 2 diabetes (T2D) in the United States. However, little is known about the differences in gene expression and transcriptomic profiles of blood in T2D between African Americans (AA) and Caucasians (CAU), and microarray analysis of peripheral white blood cells (WBCs) from these two ethnic groups will facilitate our understanding of the underlying molecular mechanism in T2D and identify genetic biomarkers responsible for the disparities.

Results: A whole human genome oligomicroarray of peripheral WBCs was performed on 144 …

The Role Of Mothers And Media On Emerging Adults’ Religious Faith And Practices By Way Of Internalization Of Prosocial Values, Carolyn Mcnamara Barry, Laura M. Padilla-Walker, Larry J. Nelson

Faculty Publications

In the current study, we investigated the role of emerging adults’ internalization of prosocial values as a mediator between maternal relationship quality and two types of media use (positive and negative) and religious faith and practices. Participants included 500 undergraduate students (ranging from 18 to 26 years; 75% European American) from five American universities. Structural equation modeling results indicated that both maternal relationship quality and positive media were related positively and indirectly (by way of prosocial values) to religious faith, and maternal relationship quality was related positively and directly to religious faith. In contrast, negative media use was related negatively …

The Zfx Gene Is Expressed In Human Gliomas And Is Important In The Proliferation And Apoptosis Of The Human Malignant Glioma Cell Line U251, Youxin Zhou, Zuopeng Su, Yulun Huang, Ting Sun, Sansong Chen, Tingfeng Wu, Guilin Chen, Xueshun Xie, Bin Li, Ziwei Du

Faculty Publications

Background: Zfx is a zinc finger protein of the Zfy family, whose members are highly conserved in vertebrates. Zfx is a shared transcriptional regulator of both embryonic stem cells (ESC) and hematopoietic stem cells (HSC), which suggests a common genetic basis of self-renewal in embryonic and adult stem cells. The level of Zfx expression correlates with aggressiveness and severity in many cancer types, including prostate cancer, breast cancer, and leukemia. However, the importance of Zfx in human glioma is largely unknown. In the present study, we examined the role of Zfx in human glioma. Methods. We detected expression levels of …
