High Frequency Pure Tone Audiometry And High Frequency Distortion Product Otoacoustic Emissions: A Correlational Analysis, Kimberly J. Lavoie

Dissertations and Theses

Previous studies show that pure tone thresholds are strongly correlated with distortion product otoacoustic emission amplitudes when evaluating the frequency range from 1 to 8 kHz (Avan & Bonfils, 1993). Little is known about correlations between these two measures at higher frequencies from 9-16 kHz. This study compared pure tone thresholds and distortion product otoacoustic emissions (DPOAEs) in this high frequency range for 29 normal hearing subjects ages 18-30. Pure tone thresholds were obtained at 250-16 kHz and distortion product otoacoustic emissions (DPOAE) 2,211-17,675 were measured in the same ears. DPOAE amplitudes were measured using a constant F1/F2 ratio of …

Snow-Patch Influence On Soil Biogeochemical Processes And Invertebrate Distribution In The Mcmurdo Dry Valleys, Antarctica, Michael N. Gooseff, John E. Barrett, Peter T. Doran, Andrew G. Fountain, W. Berry Lyons, Andrew N. Parsons, Dorota L. Porazinska, Ross A. Virginia, Diana H. Wall

Geography Faculty Publications and Presentations

The McMurdo Dry Valleys is the largest of the ice-free areas in Antarctica. Precipitation events in excess of 1 cm of snow accumulation are rare. During the winter, snow is transported by strong katabatic winds blowing from the polar plateau, and deposited into the lee of topographic features (e.g., stream channels and other topographic depressions). At the start of the austral summer (early October), as much as 10% of the valley soils may be covered by distributed snow patches. Because liquid water is the primary driver of biological, physical, and chemical processes in this polar desert, quantifying fluxes of water …

Diffractive photoproduction of vector mesons, γp → VY, where Y is a proton-dissociative system, has been measured in e+p interactions with the ZEUS detector at HERA using an integrated luminosity of 25 pb-1. The differential cross section, dσ/dt, is presented for 1.2 < -t < 12 GeV2, where t is the square of the four-momentum transferred to the vector meson. The data span the range in photon-proton centre-of-mass energy, W, from 80 GeV to 120 GeV. The t distributions are well fit by a power law, dσ/dt ∝ (-t)-n. The slope of the effective Pomeron trajectory, measured from the W dependence of the ρ0 and φ cross sections in bins of t, is consistent with zero. The ratios dσγp→φY/dt to dσγp→ρ0Y/dt and dσγp→J/ψY/dt to dσγp→ρ0Y/dt increase with increasing -t. Decay-angle analyses for ρ0, φ and J/ψ mesons have been carried out. For the ρ0 and φ mesons, contributions from single and double helicity flip are observed. The results are compared to expectations of theoretical models.

Play For Mortal Stakes: Funerals As Modernist Acts Of Fiction, Janine Marie Utell

Dissertations, Theses, and Capstone Projects

The purpose of this dissertation is to examine the ritualization of death in British literature of the interwar period and its implication for narrative and genre. The authors under consideration include poets of the Great War (Robert Graves, Charles Sorley, Isaac Rosenberg, the Sitwells), and later writers such as Katherine Mansfield, Aldous Huxley, Virginia Woolf, W. H. Auden, Ivy Compton-Bumett, and James Joyce. Using the methodology of ritual studies, an interdisciplinary approach combining the perspectives of religion, anthropology, and literary criticism, I examine how these texts create a fictive space in which death can be ritualized and how this process …

Social Experiences Of African-American Female Students On A Predominantly White Campus, Guy Alexander Sims

Dissertations and Theses @ UNI

This study examined the social experiences of African American female students at a predominantly white institution finding that in several areas of student life African American female students persisted to graduation without necessarily establishing informal social interactions within the university community. This is contrary to Vincent Tinto's posit that students who fail to make a connection with the campus community are more likely to withdraw from the institution. This study introduces the term irrelation as a descriptor of a social construct I have applied to African American female college students on the campus of a large, public, mid-western university. Irrelation …

Predicting Ghanaian Pre-Service Teachers' Intention To Teach High-Risk Sexual Behavior Prevention From Teaching Efficacy And Prevention Approach, Joseph Kwesi Ogah

Dissertations and Theses @ UNI

Youth and adolescents in African Countries have been experiencing high prevalence levels of the outcomes of high-risk sexual behavior (HRSB), such as HIV/AIDS, teenage pregnancy, illegal abortions, and dropping out of school. Education is one means by which HRSB can be reduced among adolescents, but the sensitive nature of sex education and the controversy over which prevention approach to use have made the teaching of HRSB prevention in schools a cautious undertaking. The purpose of this study was to describe (a) pre-service teachers’ efficacy beliefs for teaching HRSB prevention and (b) pre-service teachers’ preferred approach to HRSB prevention, as determinants …

Student Perceptions Of Ethics And Professionalism In Computer Science: Does Age, Gender, Or Experience Matter?, James Stuart Bohy

Dissertations and Theses @ UNI

This work explores several factors that impact ethics education in undergraduate computer science, including: the overall understanding of ethics material, any differences between male and female subjects, any differences between traditional age and non-traditional age subjects, and any differences in experience level. Instruments (attitudinal surveys and reflective scenarios) were distributed to four institutions in the Midwest; 74 out of 170 were returned.

Female subjects demonstrated a markedly better ability to distinguish between ethical and unethical behavior in the scenarios (especially in areas where the distinctions were less obvious) and produced higher quality written justifications. There were only 4 attitudinal survey …

An Investigation Of The Concept Of Balance In Children Ages 6–9: Logic And Protologic Identifiable In Making Mobiles, Seon Chun

Dissertations and Theses @ UNI

This research was conducted to explore children's construction of protologic (foreshadowing of operations) in the context of experience with balance mobiles in a constructivist setting and to explore the usefulness of making mobiles in promoting children's development of the concept of balance.

The statement of the problem is (a) Can constructivist principles of cognitive development be used to understand children's progress in the course of educational activities involving balance? If so, how? What does the progressive construction of notions about balance look like in children's behaviors? and (b) Does children's understanding of balance improve after experimenting with making mobiles?

Agricultural Land Evaluation In Black Hawk County Using Geospatial Technologies, Elisha Jasper Dung

Dissertations and Theses @ UNI

Agriculture is one of the world's most important activities supporting human life. However, the rate of agricultural land conversion to non-agricultural uses around the world, and especially in the United States is on the increase. It has been asserted that over 2,965,265 acres of U.S. agriculture lands have recently been lost per year to development, which is a rate nearly two and a half times that lost due to development in the last 10 years ( 1982-1992). This is of particular concern in Iowa which is agriculturally based because the loss of small tracts of this high-valued land may have …

A Memory-Based Approach To Cantonese Tone Recognition, Deryle W. Lonsdale, Michael Emonts

Faculty Publications

This paper introduces memory-based learning as a viable approach for Cantonese tone recognition. The memorybased learning algorithm employed here outperforms other documented current approaches for this problem, which is based on neural networks. Various numbers of tones and features are modeled to find the best method for feature selection and extraction. To further optimize this approach, experiments are performed to isolate the best feature weighting method, the best class voting weights method, and the best number of k-values to implement. Results and possible future work are discussed.

Israel, historical background of Familiarity with the historical background of ancient Israel is beneficial, even essential for students of the Book of Mormon for many reasons , including the following: (1) so readers can appreciate the historical context in which the Lehites and Mulekites originated ; (2) because the Book of Mormon prophets presupposed that their people (and latter-day readers of their records) were familiar with the Hebrew scriptures (the Ch1istian Old Testament) and Israelite. history as they refer to the Israelite Exodus from Egypt, the existence of ten "lost tribes" of Israel, and so on 1 Ne. 17) ;

Effects Of Concurrent Motor, Linguistic, Or Cognitive Tasks On Speech Motor Performance, Christopher Dromey, April Benson

Faculty Publications

This study examined the influence of 3 different types of concurrent tasks on speech motor performance. The goal was to uncover potential differences in speech movements relating to the nature of the secondary task. Twenty young adults repeated sentences either with or without simultaneous distractor activities. These distractions included a motor task (putting together washers, nuts, and bolts), a linguistic task (generating verbs from nouns), and a cognitive task(performing mental arithmetic). Lip movement data collected during the experimental conditions revealed decreases in displacement and velocity during the motor task. The linguistic and cognitive tasks were associated with increased spatiotemporal variability …

Propping And Tunneling, Eric Friedman, Simon Johnson, Todd Mitton

Faculty Publications

In countries with weak legal systems, there is a great deal of tunneling by the entrepreneurs who control publicly traded firms. However, under some conditions entrepreneurs prop up their firms, i.e., they use their private funds to benefit minority shareholders. We provide evidence and a model that explains propping. In particular, we suggest that issuing debt can credibly commit an entrepreneur to propping, even though creditors can never take possession of any underlying collateral. This helps to explain why emerging markets with weak institutions sometimes grow rapidly and why they are also subject to frequent economic and financial crises. Journal …

Blending Face-To-Face And Distance Learners In A Synchronous Class: Instructor And Learner Experiences, P. Clint Rogers, Charles R. Graham, Rus Rasmussen, J. Olin Campbell, Donna M. Ure

Faculty Publications

Like many institutions, Brigham Young University (BYU) is searching for ways to extend the reach of its programs without expanding the physical classroom and without incurring unreasonable costs. Internet supported instruction provides one alternative, with millions of students already attending Web-based classes (Gubernick & Ebeling, 1997). This case study examines the development of a class that blends distance and face-to-face students in a synchronous class. This case study focuses on how this blended learning environment was experienced by the distance and face-to-face students as well as the instructor.

The Integrated Networks Model: Explaining Resource Allocations In Networked Markets, Judy K. Frels, Tasadduq Shervani, Rajendra Kumar Srivastava

Research Collection Lee Kong Chian School Of Business

The last decade has witnessed a shift from a focus on the value created by a single firm and product to an examination of the value created by networks of firms (or product ecosystems) in which assets are comingled with external entities. The authors examine these market-based assets in the context of network markets and propose an Integrated Networks model in which three types of networks—user, complements, and producer—add value or enhance the attractiveness of the associated focal product. The authors empirically test the proposed model by surveying information technology professionals on their resource allocation decisions regarding the Unix and …

An Empirical Model Of Price And Quality Effects Of E-Commerce, Scott E. Sampson, Kendall Hulet

Faculty Publications

During the e-Commerce boom of the late 1990s it was predicted that the Internet would have a significant impact on prices of various goods and services. Whether the net impact would he positive or negative was harder to forecast, there being opposing effects. We develop a model that describes some of those effects, including information asymmetry, search costs, price dispersion, trust premiums, and convenience premiums. The model is discussed, and a major portion is statistically tested with empirical data. As an exploratory gesture, the model is extended to consider product quality effects of online shopping. The final section concludes with …

Non-Legitimate Illness, Embodied Experience And The Moral Career: The Case Of Me/Cfs, T Collett

Peninsula Medical School

The condition known as Myalgic Encephalomyelitis or Chronic Fatigue Syndrome (ME/CFS) is an illness of unknown aetiology. In the absence of any organic proof of its existence, the prevailing UK view is that it is a form of atypical depression or a somatic disorder. ME/CFS is said by sufferers to affect physical and cognitive functioning and last for years. However, many argue that because ME/CFS is seen as a psychological illness their complaints of ‘being really ill’ are not taken seriously. Based on a mixed method study of 266 persons with ME/CFS, this paper explores how individuals experience a chronic …

Farm-Level Pesticide Use In Bangladesh: Determinants And Awareness, S Rahman

School of Geography, Earth and Environmental Sciences

Farmers' awareness of beneficial and harmful effects of pesticides and factors determining use of pesticides were analyzed using survey data from 21 villages in three agro-ecological regions of Bangladesh. Pesticide cost accounts for about 7.7% of the gross value of output in cotton, 3.6% in vegetables, 2.5% in potato, 1.8% in modern rice, 1.6% in spices and less than 1% in other cereal and non-cereal crops. About 77% of farmers (highest 94% in Comilla) used pesticides at least once (37% applied once and 31% applied twice, and the rest applied for 3-5 times) in a crop season. Cultivation of traditional …

Metrics For Evaluating Human-Robot Interactions, Michael A. Goodrich, Dan R. Olsen Jr.

Faculty Publications

Metrics for evaluating the quality of a human-robot interface are introduced. The autonomy of a robot is measured by its neglect time. The robot attention demand metric measures how much of the user’s attention is involved with instructing a robot. The free-time and fan-out metrics are two ways to measure this demand. Each of them leads to estimates of the interaction effort. Reducing interaction effort without diminishing task effectiveness is the goal of human-robot interaction design.
