A Model Of Norm Development For Computer-Mediated Teamwork, Charles R. Graham

Faculty Publications

The process of establishing norms is an important aspect of group dynamics. Most, if not all, of the major models of group development incorporate norming as an important part of the process. However, little is understood and agreed on regarding how norms develop.With the increased availability and power of technology to connect people at remote sites, the popularity of computer-mediated teamwork has increased dramatically. This new communication context brings with it some dramatic differences from the traditional face-to-face context, along with a need to understand how norms develop in this environment. This study investigates the norming process engaged in by …

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.

Research Opportunities In Internal Auditing, Douglas F. Prawitt

Faculty Publications

This chapter discusses staffing and managing the internal audit function (IAF) as a component of organizational governance, and has two main purposes. First, it familiarizes interested practitioners and researchers with current trends and issues in staffing and managing the IAF. Second, it suggests questions and topics for future thinking and research among practitioners and academics. Managing and staffing an IAF is a vast and complex undertaking that remains relatively unexplored by rigorous research. The chapter contains several citations to practitioner information and academic research, but it does not attempt to include a comprehensive literature review of all relevant articles or …

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 …

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.

The Forgotten Voice Of The Oneida Stake Academy, Fred E. Woods

Faculty Publications

The Physiography class invited me to their Comet Party. We all got up at 3 o'clock a.m. and went to the academy building and there watched Halley's comet and indulged in outdoor games, wrote H. Oswald Christensen, a devoted faculty member of the Oneida Stake Academy in Preston, Idaho. His voice, along with those of many other Academy faculty members and students, must not be forgotten.

From Liverpool To Keokuk: The Mormon Maritime Migration Experience Of 1853, Fred E. Woods

Faculty Publications

In January, Fifty-three, we left our English home, Determined for the Gospel's sake, to Zion's land to come. Our family was very small, its members numbered three, Yet strong in faith of Israel's God, and full of hope were we. 'Twas not to us an easy task to bid old friends adieu, To take a long farewell of those who always had been true, To leave for aye, the cozy home we made but just before, And take a last fond look of things we should behold no more; The wind blew keen, as out we went into the cold …

The 1853 Mormon Migration Through Keokuk, Fred E. Woods, Douglas Atterberg

Faculty Publications

In May 1853, William W. Belknap, who would later serve as a major general in the Civil War and as secretary of war to President Grant, wrote to his sister, Clara, about the Mormon emigrants who were outfitting in Keokuk, Iowa, that spring and summer: "Yesterday was Sunday and I wish you had been here to go up to the Mormon Camp with me. They had preaching at three stands in three languages--English, German, and Danish. They sing --especially the Danes--very sincerely and are perfectly enthusiastic. It is a strange, strange mystery and if you were here you'd be astonished. …

Theatre In Pioneer Utah, J. Michael Hunter

Faculty Publications

The performance of theater and drama in Utah and the buildings that housed them are described. Theater was an important community project from the earliest days of Mormon settlement in Utah, beginning with the Social Hall. The Salt Lake Theatre opened in 1862 and until its demolition in 1928 was an important theater in the American West. Theater was a community project by the Mormon settlers of the Salt Lake Valley under the leadership of Brigham Young.

A Time For Change : Improving Salt Lake City, 1890-1925, J. Michael Hunter

Faculty Publications

Although visitors to Salt Lake City during its earliest years described the valley as a place of order and beauty, by the 1880s the city had become dirty, polluted, and unsanitary. This article details the efforts at improvement beginning in the 1880s, including the installation of water and sewer systems, public transportation, electricity, paved streets, and the beautification of parks and playgrounds.

Using Low-Threshold Applications And Software Templates To Improve Efficiency In An Introductory Statistics Course, Jason K. Mcdonald

Faculty Publications

This study was an exploratory study in improving efficiency in university courses by using low-cost methods of design and development that can be easily managed by university faculty. To explore this issue, we developed a lesson for the Statistics department at Brigham Young University using low-threshold applications (uses of technology that are low-cost and easy to learn) and software templates. We evaluated the lesson as a possible method to decrease the number of hours instructors were required to spend teaching in class. We discovered that students responded positively to the lesson, and that the methods of lesson design and development …

Children’S Sociable And Aggressive Behaviour With Peers: A Comparison Of The Us And Australia, And Contributions Of Temperament And Parenting Styles, Alan Russell, Craig H. Hart, Clyde C. Robinson, Susanne F. Olsen

Faculty Publications

Links between both temperament and parenting, and children’s sociable and aggressive behaviour with peers (physical and relational), were examined. The research was undertaken in two Western cultures (the United States and Australia) assumed to be similar in socialisation practices and emphases. The moderating effects of parent sex and child sex were also examined. Parents completed questionnaires on parenting styles and child temperament. Preschool teachers rated children’s aggressive and sociable behaviour. US children were rated higher on both types of aggression by teachers and on sociability, activity, and emotionality by parents. Girls were rated as more relationally aggressive and more prosocial …

Trust And The Decision To Outsource: Affective Responses And Cognitive Processes, Mark Hansen, J.L. Morrow Jr.

Faculty Publications

Many of the various forms of cooperative strategy that firms are pursuing in today’s economy entail the placing of important business functions in the hands of a partner. This paper examines the role of trust in the decision by a producer to place the marketing function in the hands of another entity, namely a cooperative. Although others have studied the effect of what may be termed general trust on inter-organizational relationships, few have examined the antecedents of that trust. We propose a model in which affective responses and cognitive processes are precursors to a sense of general trust, which, in …

The second date to remember is all of next month, February …

Can Reading Help?, Chris Crowe

Faculty Publications

I've not slept well for many months. Until recently l had assumed that my fitful nights were merely the combined effects of impending writing deadlines, ALAN presidential duties, middle age, a long list of incomplete house and yard chores, a six-digit mortgage, my university students and classes, a neurotic and noisy cat, and two teenage daughters.

Some nights are worse than others, and I've supposed that when stress goes up, sleep goes down. But I've also noticed lately that when things go bump in the night, I jerk awake wondering if it was just wind, the dog, a neighbor's car …

Unfinished Business, Chris Crowe

Faculty Publications

This is my thirtieth and final YA literature column for English Journal. Beginning with the next issue of EJ, Donald R. Gallo, one of the leading experts in YA literature today—and the leding YA short story anthologist in America—will take my place. Don has some terrific ideas, and in the future this column, which will be renamed "Bold Books for Innovative Teaching," will provide EJ subscribers with useful and thought-provoking insights into books for teenage readers.

Responding To The Demise Of Adolescent Artmaking: Charting The Course Of Adolescent Development In An Exceptional Art Classroom, Mark Graham

Faculty Publications

Adolescent artistic developmental potential is often underestimated, ignored, or dismissed as irrelevant. This article argues that the deliberate cultivation of artistry is neglected and the task of developing mastery in any visual language is rarely attempted. By adolescence, most children give up the visual arts as a means of understanding or expression. Although drawing is accepted as a fundamental skill in most secondary art programs, there are different opinions on how to teach drawing, and to whom drawing should be taught. Endpoints of development and the role of cultural influences are two areas that invite different points of view. This …

Milliwatt Power Deep Ultraviolet Light-Emitting Diodes Over Sapphire With Emission At 278 Nm, J. P. Zhang, A. Chitnis, V. Adivarahan, S. Wu, V. Mandavilli, R. Pachipulusu, M. Shatalov, Grigory Simin, J. W. Yang, M. Asif Khan

Faculty Publications

We report on AlGaN multiple-quantum-well (MQW)-based deep ultraviolet light-emitting diodes over sapphire with peak emission at 278 nm. A new buffer layer growth process was used to reduce the number of defects and hence the nonradiative recombination. The improved material quality and carrier confinement resulted in pulsed powers as high as 3 mW at 278 nm and a significantly reduced deep-level-assisted long-wavelength emission.

Level Oriented Formal Model For Asynchronous Circuit Verification And Its Efficient Analysis Method, Eric G. Mercer, Tomoya Kitai, Chris Myers, Yusuke Oguro, Tomohiro Yoneda

Faculty Publications

Using a level-oriented model for verification of asynchronous circuits helps users to easily construct formal models with high readability or to naturally model datapath circuits. On the other hand, in order to use such a model on large circuits, techniques to avoid the state explosion problem must be developed. This paper first introduces a level-oriented formal model based on time Petri nets, and then proposes its partial order reduction algorithm that prunes unnecessary state generation while guaranteeing the correctness of the verification.

On-Chip Actuation Of An In-Plane Compliant Bistable Micromechanism, Michael S. Baker, Larry L. Howell

Faculty Publications

A compliant bistable micromechanism has been developed which can be switched in either direction using on-chip thermal actuation. The energy storage and bistable behavior of the mechanism is achieved through the elastic deflection of compliant segments. The Pseudo-Rigid-Body Model was used for the compliant mechanism design, and for analysis of the large deflection flexible segments. To achieve on-chip actuation, the mechanism design was optimized to allow it to be switched using linear motion thermal actuators. The modeling theory and analysis are presented for three design iterations, with two iterations fabricated in the MUMP's process and the third in the SUMMiT …

An Assessment Of Seawinds On Quikscat Wind Retrieval, David Draper, David G. Long

Faculty Publications

The scatterometer ocean wind retrieval process produces several possible solutions or ambiguities at each point, requiring a separate ambiguity selection step to infer a unique wind vector field. An ambiguity selection error occurs when the selected wind vector is not the closest ambiguity to the true wind. The current ambiguity selection routine for SeaWinds is ad hoc, but performs well under most circumstances. Factors such as instrument noise and rain can also cause the estimated wind flow to deviate from the true wind. A quality assurance (QA) analysis is performed to assess the ambiguity selection effectiveness and noise level of …

Biaxial Strain-Modified Valence And Conduction Band Offsets Of Zinc-Blende Gan, Gap, Gaas, Inn, Inp, And Inas, And Optical Bowing Of Strained Epitaxial Ingan Alloys, Gus L. W. Hart, P. R. C. Kent, Alex Zunger

Faculty Publications

Using density-functional calculations, we obtain the (001) biaxial strain dependence of the valence and conduction band energies of GaN, GaP, GaAs, InN, InP, and InAs. The results are fit to a convenient-to-use polynomial and the fits provided in tabular form. Using the calculated biaxial deformation potentials in large supercell empirical psuedopotential calculations, we demonstrate that epitaxial strain reduces the InGaN alloy bowing coefficient compared to relaxed bulk alloys.

The Anti-Monopoly Origins Of The Patent And Copyright Clause, Tyler T. Ochoa, Mark Rose

Faculty Publications

The British experience with patents and copyrights prior to 1787 is instructive as to the context within which the Framers drafted the Patent and Copyright Clause. The 1624 Statute of Monopolies, intended to curb royal abuse of monopoly privileges, restricted patents for new inventions to a specified term of years. The Stationers' Company, a Crown-chartered guild of London booksellers, continued to hold a monopoly on publishing, and to enforce censorship laws, until 1695. During this time, individual titles were treated as perpetual properties held by booksellers. In 1710, however, the Statute of Anne broke up these monopolies by imposing strict …

Brain Potentials Elicited By Prose-Embedded Linguistic Anomalies, Mark D. Allen, Kayo Inoue, Judith Mclaughlin, Lee Osterhout

Faculty Publications

Linguistic theories distinguish between syntax (sentence form) and semantics (sentence meaning). Correspondingly, recent studies have shown that syntactic and semantic anomalies elicit distinct changes in the event-related brain potential (ERP). However, these results have been obtained with highly artificial methodologies and have not yet been generalized to more natural reading conditions. Here, we recorded ERPs while subjects read a naturalistic prose passage. The subjects either read for comprehension with no other task being assigned or read for comprehension and made acceptability judgments after each sentence. Consistent with prior work and regardless of the subjects’ assigned task, syntactic anomalies elicited a …

Urinary Excretion Of Dithiocarbamates And Selfreported Cruciferous Vegetable Intake: Application Of The ‘Method Of Triads’ To A Foodspecific Biomarker, Jay H. Fowke, James R. Hébert, Jed W. Fahey

Faculty Publications

Objective: Greater intake of Cruciferous vegetables (e.g. broccoli) may prevent cancer at several sites. Urinary excretion of isothiocyanate conjugates (dithiocarbamates, DTC) provides a specific biomarker of Cruciferous vegetable consumption suitable for epidemiological investigations. However, no gold-standard referent is available for evaluating urinary DTC levels as an estimator of Cruciferous vegetable consumption. We compared urinary DTC levels to intake as measured by two selfreported dietary assessment techniques. Design: Cruciferous vegetable consumption was measured before and after a behavioural dietary intervention using multiple 24-hour recalls (24HR), a foodcounting questionnaire (VFQ) and urinary DTC excretion levels. Analysis included a structural equation approach (Method …

Relational And Physical Victimization Within Friendships: Nobody Told Me There'd Be Friends Like These, Nicki R. Crick, David A. Nelson

Faculty Publications

In past research, relational and physical forms of peer victimization have been identified that have been shown to be significantly associated with social–psychological maladjustment. These forms of victimization, although studied primarily within the group peer context, also occur within dyadic relationships such as friendships. Gender differences in friend victimization and the association between friend victimization and children's social–psychological adjustment were examined. Results showed that boys were more physically victimized by their friends than were girls. Girls were more relationally than physically victimized by their friends. Friend victimization was related to adjustment difficulties for both boys and girls; however, friend physical …

Bergmann's Rule In Ectotherms: A Test Using Freshwater Fishes, Mark C. Belk, Derek D. Houston

Faculty Publications

Understanding patterns of variation in body size within and among species is a central question in evolutionary ecology (Schlichting and Pigliucci 1998). The most well known pattern of variation in body size is Bergmann's rule (Bergmann 1847; Mayr 1956). The intraspecific version of Bergmann's rule holds that within endothermic species, body size increases with increasing latitude (or decreasing temperature; Blackburn et al. 1999; Ashton et al. 2000). In general, mammals conform to this rule (Ashton et al. 2000).

Coordinated Target Assignment And Intercept For Unmanned Air Vehicles, Erik P. Anderson, Randal W. Beard, Michael A. Goodrich, Timothy W. Mclain

Faculty Publications

This paper presents an end-to-end solution to the cooperative control problem represented by the scenario where unmanned air vehicles (UAVs) are assigned to transition through known target locations in the presence of dynamic threats. The problem is decomposed into the subproblems of: 1) cooperative target assignment; 2) coordinated UAV intercept; 3) path planning; 4) feasible trajectory generation; and 5) asymptotic trajectory following. The design technique is based on a hierarchical approach to coordinated control. Simulation results are presented to demonstrate the effectiveness of the approach.
