Estimating Dysphonia Severity In Continuous Speech: Application Of A Multi-Parameter Spectral/Cepstral Model, Christopher Dromey, Shaheen N. Awan, Nelson Roy Jan 2009

Estimating Dysphonia Severity In Continuous Speech: Application Of A Multi-Parameter Spectral/Cepstral Model, Christopher Dromey, Shaheen N. Awan, Nelson Roy

Faculty Publications

The purpose of the study was to identify a sub-set of spectral/cepstral-based analysis methods that would most effectively predict dysphonia severity (as estimated via auditory-perceptual analysis) in samples of continuous speech. Acoustic estimates of dysphonia severity were used as an objective treatment outcomes measure in a set of pre- vs post-treatment speech samples. Pre- and post-treatment continuous speech samples from 104 females with primary muscle tension dysphonia (MTD) were rated by listeners using a 100 point visual analogue scale (VAS) and analysed acoustically with spectral/cepstral-based measures. Stepwise linear regression produced a three-factor model consisting of the cepstral peak prominence (CPP); …

Laryngeal-Level Amplitude Modulation In Vibrato, Christopher Dromey, Lorie Reese, J Arden Hopkin Jan 2009

Laryngeal-Level Amplitude Modulation In Vibrato, Christopher Dromey, Lorie Reese, J Arden Hopkin

Faculty Publications

Summary: The goal of this investigation was to test a new methodology for measuring amplitude modulation (AM) at the level of the vocal folds during vibrato in trained singers, because previous research has suggested that AM arises in large part as an acoustic epiphenomenon through an interaction of the harmonics in the laryngeal source with the resonances of the vocal tract as the fundamental frequency oscillates. A within-subjects model was used to compare vocal activity across three pitch and three loudness conditions. Seventeen female singers with a range of training and experience were recorded with a microphone and an electroglottograph …

Articulatory Changes In Muscle Tension Dysphonia: Evidence Of Vowel Space Expansion Following Manual Circumlaryngeal Therapy, Christopher Dromey, Nelson Roy, Shawn L. Nissen, Shimon Sapir Jan 2009

Articulatory Changes In Muscle Tension Dysphonia: Evidence Of Vowel Space Expansion Following Manual Circumlaryngeal Therapy, Christopher Dromey, Nelson Roy, Shawn L. Nissen, Shimon Sapir

Faculty Publications

In a preliminary study, we documented significant changes in formant transitions associated with successful manual circumlaryngeal treatment (MCT) of muscle tension dysphonia (MTD), suggesting improvement in speech articulation. The present study explores further the effects of MTD on vowel articulation by means of additional vowel acoustic measures. Pre- and post-treatment audio recordings of 111 women with MTD were analyzed acoustically using two measures: vowel space area (VSA) and vowel articulation index (VAI), constructed using the first (F1) and second (F2) formants of 4 point vowels/ ", i, æ, u/, extracted from eight words within a standard reading passage. Pairwise t-tests …

Multiple Pathways To Functional Impairment In Obsessive–Compulsive Disorder, Scott A. Baldwin, Yeraz Markarian, Michale J. Larson, Mirela A. Aldea, Daniel Good, Arjan Berkeljon, Tanya K. Murphy, Eric A. Storch, Dean Mckay

Faculty Publications

Obsessive–compulsive disorder (OCD) is a chronic and debilitating condition that is relatively common in both children and adults, and it is associated with a wide range of functional impairments. Mental health researchers and practitioners have placed considerable attention on OCD over the past two decades, with the goal of advancing treatment and understanding its etiology. Until recently, it was unknown to what extent this disorder was associated with functional impairment. However, recent research shows that the condition has significant social and occupational liabilities. This article discusses etiology, common symptom presentations (including comorbid and ancillary symptoms), basic OCD subtypes, neuropsychological functioning, …

Faculty Publications

Existing literature demonstrates that there is a close link between entrepreneurship and economic growth, primarily because new businesses contribute to employment creation. According to U.S. Census data, small businesses employ up to 50% of the private work force and generate 60% to 80% of the net new jobs each year. In a time where countries face multiple economic challenges, entrepreneurs could play a significant role in the economic growth of a country, a state, or a city.

On The Contribution Of Perceptual Fluency And Priming To Recognition Memory, M. A. Conroy, Ramona O. Hopkins, L. R. Squire Jan 2009

On The Contribution Of Perceptual Fluency And Priming To Recognition Memory, M. A. Conroy, Ramona O. Hopkins, L. R. Squire

Faculty Publications

Repetition priming has been shown to be independent of recognition memory. Thus, the severely amnesic patient E.P. has demonstrated intact stem completion priming and perceptual identification priming, despite at-chance performance on recognition memory tasks. It has also been shown that perceptual fluency can influence feelings of familiarity, in the sense that items perceived more quickly tend to be identified as familiar. If studied items are identified more fluently, due to perceptual priming, and fluency leads to familiarity, why do severely amnesic patients perform no better than chance on recognition memory tasks? One possibility is that severely amnesic patients do not …

The Potential Of Asynchronous Video In Online Education, Michael E. Griffiths, Charles R. Graham Jan 2009

The Potential Of Asynchronous Video In Online Education, Michael E. Griffiths, Charles R. Graham

Faculty Publications

There are differences in the benefits that are afforded by the two extremes of face-to-face and distance education. University campus courses are based on the assumption that the student community and interaction between learners and an expert teacher in the same physical location is essential to the learning process. In comparison, distance education provides a learner with flexibility, individualized learning, lower costs, and self-determination in the learning process. Much research has been invested into modern approaches that may be able to harness key benefits from both face-to-face and distance education. One recent breakthrough has come in the use of asynchronous …

Diagramming Tpack In Practice: Using An Elaborated Model Of The Tpack Framework To Analyze And Depict Teacher Knowledge, Suzy Cox, Charles R. Graham Jan 2009

Diagramming Tpack In Practice: Using An Elaborated Model Of The Tpack Framework To Analyze And Depict Teacher Knowledge, Suzy Cox, Charles R. Graham

Faculty Publications

The introduction of the TPACK model by Mishra and Koehler (2006) has had a profound impact on the field of educational technology. It has inspired teachers, teacher educators, and educational technologists to reevaluate their knowledge and use of technology in the classroom. While Koehler, Mishra, and others have attempted to define and measure TPACK, the framework is not yet fully understood (Angeli & Valanides, 2009). Thus far, the explanations of technological pedagogical content knowledge and its associated constructs that have been provided are not clear enough for researchers to agree on what is and is not an example of each …

Factors Contributing To Improved Teaching Performance, Whitney Ransom Mcgowan, Charles R. Graham Jan 2009

Factors Contributing To Improved Teaching Performance, Whitney Ransom Mcgowan, Charles R. Graham

Faculty Publications

This article focuses upon the quality and scholarship of teaching as it pertains to educational and faculty development. We outline what more than 200 faculty members at one institution have done over a 3-year period to make significant and sustained improvements in their teaching, surprisingly with minimal effort. The top three factors leading to improvement were active/practical learning, teacher/student interactions, and clear expectations/learning outcomes. We provide practical applications for change and suggestions for future research.

The Balanced Scorecard As A Strategy-Evaluation Tool: The Effects Of Implementation Involvement And A Causal-Chain Focus, William B. Tayler Jan 2009

The Balanced Scorecard As A Strategy-Evaluation Tool: The Effects Of Implementation Involvement And A Causal-Chain Focus, William B. Tayler

Faculty Publications

This paper uses an experiment to examine whether involvement in scorecard implementation can mitigate the effects of motivated reasoning that occur when the scorecard is framed as a causal chain rather than merely as a balanced set of measures. Psychological research on motivated reasoning suggests that managers will evaluate and interpret data in ways consistent with their preferences, increasing their tendency to arrive at conclusions that are consistent with their desired conclusions (Kunda 1990). Consistent with that research, results of my study show that managers who are involved in selecting strategic initiatives perceive those initiatives as having been more successful …

Blind Insights: A New Technique For Testing A Priori Hypotheses With Qualitative Methods, Eric D. Derosia, Glenn L. Christensen Jan 2009

Blind Insights: A New Technique For Testing A Priori Hypotheses With Qualitative Methods, Eric D. Derosia, Glenn L. Christensen

Faculty Publications

The purpose of this paper is to propose and illustrate blind qualitative hypothesis testing, which is a qualitative research technique that further generalizes the well-known notion of “blindness” in research to include a qualitative researcher. The technique introduces a method to test a priori hypotheses using qualitative, emergent observation and analysis without the biasing influence of prior knowledge of the hypotheses being tested.

Disclosure Quality And The Mispricing Of Accruals And Cash Flow, Michael S. Drake, James N. Myers, Linda A. Myers Jan 2009

Disclosure Quality And The Mispricing Of Accruals And Cash Flow, Michael S. Drake, James N. Myers, Linda A. Myers

Faculty Publications

In this paper, we investigate the role that disclosure quality plays in the accurate valuation of accruals and cash flow. We predict that stock prices of firms with higher-quality disclosures more accurately reflect the persistence of accruals and cash flow. We test our predictions using analyst ratings of disclosure published in the annual Association for Investment Management and Research (AIMR) Corporate Information Committee Reports for the years 1982 through 1996. The results provide strong evidence of mispricing for the subset of firms with lower-quality disclosures and of a significant reduction in mispricing for the subset of firms with higher-quality disclosures. …

A Sense Of Things To Come: Future Research Directions In Sensory Marketing, Ryan S. Elder, Nilufer Z. Aydinoglu, Victor A. Barger, Cindy Caldara, Helen Haeeun Chun, Chan Jean Lee, Gina Mohr, Antonios Stamatogiannakis

Faculty Publications

The exciting exploration on sensory marketing presented in this book is just the foundation upon which to build future research. There are myriad unexplored questions and innumerable directions in which to take this research. Our goal in this chapter is not to provide an exhaustive array of these future directions, but rather to stimulate the reader into exploring new ideas. We present possible future directions for each sense individually (vision, audition, smell, touch, taste), and conclude with ideas for future research addressing the interplay among multiple senses within consumer behavior.

Earnings Misstatements, Restatements, And Corporate Governance, William G. Heninger, Yongtae Kim, Sandeep Nabar Jan 2009

Earnings Misstatements, Restatements, And Corporate Governance, William G. Heninger, Yongtae Kim, Sandeep Nabar

Faculty Publications

High profile financial restatements from companies like Enron, Worldcom, Healthsouth, and Tyco as well as less celebrated restatements from such companies as Red Hat, Nortel, and Bristol-Myers Squibb have shaken public trust in the U.S. capital market. The restating companies have watched their credit ratings drop, market values erode, and occasionally even faced bankruptcy (Palmrose et al. 2004; Hirschey et al. 2005). The preponderance of restatements, in part, led to the enactment of the Sarbanes-Oxley Act which reemphasized the need for, and the importance of, strong corporate governance.

An Exploration Of A Model Of Social Networks And Multilateral Negotiations, Bruce Money, Chad R. Allred Jan 2009

An Exploration Of A Model Of Social Networks And Multilateral Negotiations, Bruce Money, Chad R. Allred

Faculty Publications

Multilateral (many‐party) negotiations are much more complex than traditional two‐party negotiations. In this article, we explore a model of social network activity, especially clique formation, among parties engaged in multilateral negotiation and the implications that such networks might have on the negotiation process and outcome. Using data collected from 375 subjects participating in a negotiation simulation, our results reveal that, primarily, the negotiator’s perspectives of clique formation (coalition building) — both his or her own and the other party’s — have unique effects on the integrative, problem‐solving approaches used in the process and on the negotiator’s satisfaction with outcomes. Secondarily, …

Optimal Defaults And Active Decisions, Gabriel D. Carroll, James J. Choi, David Laibson, Brigitte C. Madrian, Andrew Metrick Jan 2009

Optimal Defaults And Active Decisions, Gabriel D. Carroll, James J. Choi, David Laibson, Brigitte C. Madrian, Andrew Metrick

Faculty Publications

Defaults often have a large influence on consumer decisions. We identify an overlooked but practical alternative to defaults: requiring individuals to make an explicit choice for themselves. We study such “active decisions” in the context of 401(k) saving. We and that compelling new hires to make active decisions about 401(k) enrollment raises the initial fraction that enroll by 28 percentage points relative to a standard opt-in enrollment procedure, producing a savings distribution three months after hire that would take 30 months to achieve under standard enrollment. We also present a model of 401(k) enrollment and derive conditions under which the …

Determinants Of Vertical Integration: Financial Development And Contracting Costs, Daron Acemoglu, Simon Johnson, Todd Mitton Jan 2009

Determinants Of Vertical Integration: Financial Development And Contracting Costs, Daron Acemoglu, Simon Johnson, Todd Mitton

Faculty Publications

We study the determinants of vertical integration in a new data set of over 750,000 firms from 93 countries. We present a number of theoretical predictions on the interactions between financial development, contracting costs, and the extent of vertical integration. Consistent with these predictions, contracting costs and financial development by themselves appear to have no effect on vertical integration. However, we find greater vertical integration in countries that have both greater contracting costs and greater financial development.We also show that countries with greater contracting costs are more vertically integrated in more capital-intensive industries.

The Cmc Interactivity Model: How Interactivity Enhances Communication Quality And Process Satisfaction In Lean-Media Groups, Paul Benjamin Lowry, Nicholas C. Romano Jr., Jeffrey L. Jenkins, Randy W. Guthrie Jan 2009

The Cmc Interactivity Model: How Interactivity Enhances Communication Quality And Process Satisfaction In Lean-Media Groups, Paul Benjamin Lowry, Nicholas C. Romano Jr., Jeffrey L. Jenkins, Randy W. Guthrie

Faculty Publications

Process satisfaction is one important determinant of work group collaborative system adoption, continuance, and performance. We explicate the computermediated communication (CMC) interactivity model (CMCIM) to explain and predict how interactivity enhances communication quality that results in increased process satisfaction in CMC-supported work groups. We operationalize this model in the challenging context of very large groups using extremely lean CMC. We tested it with a rigorous field experiment and analyzed the results with the latest structural equation modeling techniques. Interactivity and communication quality dramatically improved for very large groups using highly lean CMC (audience response systems) over faceto- face groups. Moreover, …

Enhancing Cultural Competence In Financial Counseling And Planning: Understanding Why Families Make Religious Contributions, Loren D. Marks, David C. Dollahite, Jeffrey P. Dew Jan 2009

Enhancing Cultural Competence In Financial Counseling And Planning: Understanding Why Families Make Religious Contributions, Loren D. Marks, David C. Dollahite, Jeffrey P. Dew

Faculty Publications

Some highly religious individuals contribute a relatively high percent of their income (e.g., 10-15% or more) to their faith communities. This study used a racially and religiously diverse sample and employed qualitative methods to investigate why these individuals give. Five themes emerged from the grounded-theory analysis. Four themes concerned why families gave: a) out of a sense of obedience/duty, b) to express thanksgiving and feel joy, c) because they feel that it is a wise investment, and d) to promote social justice and charity. The final theme that emerged was that they give despite their financial challenges. Based on these …

Religious Affiliation As A Correlate Of Linguistic Behavior, Wendy Baker-Smemoe, David Bowie Jan 2009

Religious Affiliation As A Correlate Of Linguistic Behavior, Wendy Baker-Smemoe, David Bowie

Faculty Publications

The current study examined whether religious affiliation in Utah County, Utah affected the production of several vowel mergers typical of the area (i.e., fell-fail, pool-pole-pull,card-cord). To do so, we asked selfidentified members of the Church of Jesus Christ of Latter-day Saints (Mormons) and self-identified non- Mormons to produce these vowel contrasts. Next, three naïve raters trained in phonetics but unfamiliar with how English is spoken in Utah were asked to judge which of the two vowels in a vowel pair contrast was produced by the speakers. Findings demonstrated clear evidence of differences based on selfdescribed religious affiliation for several of …

To Give Is Better Than To Receive: The Benefits Of Peer Review To The Reviewer’S Own Writing, Wendy Baker, Kristi Lundstrom Jan 2009

To Give Is Better Than To Receive: The Benefits Of Peer Review To The Reviewer’S Own Writing, Wendy Baker, Kristi Lundstrom

Faculty Publications

Although peer review has been shown to be beneficial in many writing classrooms, the benefits of peer review to the reviewer, or the student giving feedback, has not been thoroughly investigated in second-language writing research. The purpose of this study is to determine which is more beneficial to improving student writing: giving or receiving peer feedback. The study was conducted at an intensive English institute with ninety-one students in nine writing classes at two proficiency levels. The ‘‘givers’’ reviewed anonymous papers but received no peer feedback over the course of the semester, while the ‘‘receivers’’ received feedback but did not …

Imaginative Instruction: What Master Storytellers Can Teach Instructional Designers, Jason K. Mcdonald Jan 2009

Imaginative Instruction: What Master Storytellers Can Teach Instructional Designers, Jason K. Mcdonald

Faculty Publications

Good instructional storytelling engages students’ attention and cognitive abilities to the end of more effective learning, and instructional researchers have discussed whether the principles of storytelling could lead to the same or similar results if applied to educational situations beyond only telling traditional stories. But despite this potential, the principles of storytelling are seemingly underutilized by today’s instructional designers. This study investigates what instructional designers might learn from another design field that is more experienced in the art of storytelling, specifically that of film production. Eight filmmakers who have successfully produced films that motivate, inspire, and educate were interviewed to …

Intra-Speaker Variability In Palatometric Measures Of Consonant Articulation, Christopher Dromey, Marybeth Sanders Jan 2009

Intra-Speaker Variability In Palatometric Measures Of Consonant Articulation, Christopher Dromey, Marybeth Sanders

Faculty Publications

Electropalatometry is a useful clinical and research tool for measuring linguapalatal contact. The goal of this study was to examine intra-speaker variability in performance. Twenty individuals spoke VCV nonsense words using a schwa in the initial position, the 15 palatal consonants, and three corner vowels, /ɑ/, /i/, /u/. A variability index was created to examine speaker consistency.
Different aspects of articulation (i.e. place, manner, voicing, coarticulation) were compared. Significant differences for variability were found for place of articulation in the /i/ vowel context and for manner of articulation in the /ɑ/ vowel context. Also for the /ɑ/ vowel, significant differences …

Design, Manufacture, Mechanical Testing And Numerical Modelling Of An Asymmetric Composite Crossbow Limb, Amandeep S. Virk, J. Summerscales, W. Hall, S. M. Grove, M. E. Miles Jan 2009

Design, Manufacture, Mechanical Testing And Numerical Modelling Of An Asymmetric Composite Crossbow Limb, Amandeep S. Virk, J. Summerscales, W. Hall, S. M. Grove, M. E. Miles

School of Engineering, Computing and Mathematics

This paper considers the design, manufacture, mechanical testing and numerical analysis of a crossbow beam (limb). The limb should be lightweight and permit a high deflection of the beam's tip in order to achieve a good ballistic performance. Consequently, fibre-reinforced polymer matrix composites are suitable candidate materials. However, carbon fibres were considered too brittle for this application. Aramid fibres combine low density and high stiffness but are weak in compression. E-glass fibres are relatively flexible but are of high density. The optimised design developed here uses aramid fibres on the tension face with E-glass fibres on the compression side. This …

N-Gram-Based Search Procedure, Szymon Woznica Jan 2009

N-Gram-Based Search Procedure, Szymon Woznica

Computer Science

Efficient querying and discovery of meaningful patterns in data becomes more and more important with accelerating growth of data published every day on the Internet. Tree pruning-based algorithms used in most popular search programs have troubles when dealing with infrequent query strings, limiting the number of returned results that might be of interest to the user. Furthermore, the existing tools are not capable of finding data patterns that could inform the user about the frequency of occurrence and location of a specific set of words in large, user-defined sets of textual data, in an efficient manner. In this paper, we …
