A Unified Design Framework For Learning Objects And Educational Discourse, David Wiley, Sandie Waters

Faculty Publications

Instructional design is largely a matter of scope and sequence, and designing instruction with learning objections is no exception. Traditionally, learning objects are considered atomic units of educational content, and designing instruction with learning objects means scoping instructional messages and determining sequences for delivering the messages. We argue that instructional methods that rely heavily on social interaction can be implemented with learning objects when these are understood to be reusable scaffolds for scoping and sequencing what learners say to each other during instructional interactions.

The Book Of Breathings In Its Place, Kerry M. Muhlestein

Faculty Publications

Michael D. Rhodes's publication on the Hor Book of Breathings is an unusual book in many ways. It is a scholarly Egyptological work, dealing with an understudied type of text from an understudied era of Egyptian history, appearing in the midst of a series that has been dedicated to the exploration of a book considered to be scripture by the Latter-day Saints. Additionally, it deals with what many have incorrectly considered to be a text that can be used to test the revelatory ability of the founder of the Church of Jesus Christ of Latterday Saints.

Prioritization Methods For Accelerating Mdp Solvers, Kevin Seppi, David Wingate

Faculty Publications

The performance of value and policy iteration can be dramatically improved by eliminating redundant or useless backups, and by backing up states in the right order. We study several methods designed to accelerate these iterative solvers, including prioritization, partitioning, and variable reordering. We generate a family of algorithms by combining several of the methods discussed, and present extensive empirical evidence demonstrating that performance can improve by several orders of magnitude for many problems, while preserving accuracy and convergence guarantees.

Seasonal Acceptance Of Fourwing Saltbush By Sheep When Crested Wheatgrass Is The Alternative, Val J. Anderson, R. D. Horrocks, Christine W. Royer, Stephen B. Monsen

Faculty Publications

Many sagebrush-grass ranges have been seeded to crested wheatgrass [Agropyron desertorum (Fischer ex Link) Shultes]. These ranges are generally nutritionally inadequate for sheep (Ovis aries L.), except for short grazing periods in the spring and fall. To increase production and diversity, particularly crude protein for late-season grazing, fourwing saltbush [Atriplex canescens (Pursch.) Nutt.] was planted in an existing stand of crested wheatgrass. Quantification of sheep forage preferences on these improved ranges aids in determining the length of the grazing season and the extent to which shrubs provide the supplemental nutrition required. This seasonal grazing study was conducted on a characteristic …

Network Model For Mimo Systems With Coupled Antennas And Noisy Amplifiers, Michael A. Jensen, Matthew L. Morris

Faculty Publications

This work presents a framework for the analysis of mutually-coupled antennas in a multiple-input multiple-output system. The approach uses network theory to formulate the transfer matrix relating the signals input to the transmit antennas to the signals at the output of the receiver front end. This transfer function includes the coupled transmit and receive antennas, the multipath propagation channel, the receiver matching network, and a realistic noise model for the receive amplifiers. Application of the formulation to coupled dipole antennas characterized using full-wave electromagnetic analysis illustrates the performance gains possible from matching the coupled antenna/receive amplifier subsystem for minimum noise …

The Kinderhook Plates, The Tucson Artifacts, And Mormon Archeological Zeal, J. Michael Hunter

Faculty Publications

“The Kinderhook Plates, the Tucson Artifacts, and Mormon Archeological Zeal” discusses Mormon archeological zeal, or the short-sighted enthusiasm shown by members of The Church of Jesus Christ of Latter-day Saints (LDS Church) regarding relics or artifacts that might "prove" the veracity of the Book of Mormon or even of the LDS Church. This article summarizes the history of both the Kinderhook Plates and the Tucson Artifacts within this context, stating that the Kinderhook Plates have been proven fraudulent but that the Tucson Artifacts still provide mystery to researchers. The Kinderhook Plates were created by three conspirators who lived in Kinderhook, …

The Medieval Holocaust: The Approach Of The Plague And The Destruction Of Jews In Germany, 1348-1349, Albert Winkler

Faculty Publications

When the Black Death approached the German Empire in 1348, civic authorities in Germany tried to prevent the disease from striking their cities. No one knew what the Plague was, but there were unfounded rumors that the contagion was caused by Jews who were poisoning the water sources. Civic authorities soon tortured Jews for confessions, and the largest single persecution of Jews in Germany before the 1940s broke out. Jews were attacked in more than three hundred communities, their wealth was plundered, and many thousands were burned to death. The pogroms in Strasbourg and Basel are well-documented examples of what …

Job Demands And Job Search Among High-Level Managers In The United States And Europe, John B. Bingham, Wendy R. Boswell, John W. Boudreau

Faculty Publications

High-level managers are often faced with challenging demands at work, and much of the managerial development literature has researched the responses to these challenges. The authors propose an extension to this research by investigating the influence of challenge-related and obstacle- related job demands on job search among a sample of U.S. managers and a sample of international managers. Specifically, the authors propose divergent relationships among job search and the type of job demands managers experience, and we also explore the mediating effect of job satisfaction. The authors’ study provides further insight into the complexities of managerial responsibilities and their behavioral …

Creating Breadth In Business Education Through Service-Learning, Paul C. Godfrey, Louise M. Illes, Gregory R. Berry

Faculty Publications

We argue service-learning pedagogy and the associated educational experiences provide a partial solution to the significant problem of narrowness in business education. Servicelearning pedagogy seeks to balance academic rigor with practical relevance, set in a context of civic engagement, which furnishes students with a broader and, we argue, richer, educational experience. We present four specific critiques of business education: (1) the business curriculum focuses on functional and discrete rather than cross-functional and holistic knowledge; (2) coursework emphasizes practical problem-solving “tool kits” rather than deep theoretical knowledge; (3) the underlying paradigm of business education views humanity and human interactions in purely …

Measuring Organizational Safety And Effectiveness At Nasa, Daniel S. Wong, Vinit M. Desai, Peter Madsen, Karlene H. Roberts, Anthony Ciavarelli

Faculty Publications

Many project managers may be fully aware of the safety risks within their organizations. What they may not know, however, is that many of these risks are caused by the underlying safety culture of the organization rather than human individual differences in the organization. This article argues that managers can mitigate safety risks by obtaining a better understanding of their organizations’ culture. The researchers created a management metric that enables engineering/project managers to identify positive and negative aspects of safety that are tied to their organizations’ cultures. The article presents a process that managers can use to increase safety and …

Deception Detection Through Automatic, Unobtrusive Analysis Of Nonverbal Behavior, Thomas O. Meservy, Matthew L. Jensen, John Kruse, Judee K. Burgoon, Jay F. Nunamaker Jr., Douglas P. Twitchell, Gabriel Tsechpenakis, Dimitris N. Metaxas

Faculty Publications

Every day, hundreds of thousands of people pass through airport security checkpoints, border crossing stations, or other security screening measures. Security professionals must sift through countless interactions and ferret out high-risk individuals who represent a danger to other citizens. During each interaction, the security professional must decide whether the individual is being forthright or deceptive. This task is difficult because of the limits of human vigilance and perception and the small percentage of individuals who actually harbor hostile intent. Our research initiative is based on a behavioral approach to deception detection. We attempted to build an automated system that can …

Shared Experience Building Around The Family Crucible Of Cancer, W. David Robinson, Jason S. Carroll, Wendy L. Watson

Faculty Publications

This study was designed to gain a greater understanding of the effects cancer has on families while simultaneously developing family therapy interventions that are helpful for families experiencing the crucible of cancer. On the basis of an action research paradigm, the authors designed an intensive case-analysis protocol involving reflective interviewing to learn about the personal perspectives of family members who participate in therapeutic treatment for cancer. An integration of reflective insight by the families, their therapist, and the research team ultimately revealed that cancer families face an ongoing struggle (a) between feelings of isolation and connectedness, (b) to make meaning …

Post Reformation Ecclesiology And Missiology--From The Radicals To Wesley: Moving Out Of The Shadow Of Luther And Calvin, Woodrow W. Whidden

Faculty Publications

Whidden’s essay compares the key theological/ecclesiological factors of the Magisterial Reformation tradition with the Radical and Wesleyan ethos and their respective visions of discipleship, theology, ethics, and mission. He then argues that movements which are Arminian in their soteriology; functional, not institutional, in their ecclesiology; and emphasize discipleship (including strict discipline), sanctification, and Gospel ethics are more likely to have a missional bent.

The Epistle To The Hebrews And Patron-Client Relationships: Toward A Missiological Appropriation, Cheryl D. Doss

Faculty Publications

Missionaries in cultures where patron-client relationships are common can find their participation in such relationships difficult. Recent New Testament scholarship has illuminated the patron-client relationships implicitly described in the epistle to the Hebrews. Utilizing this scholarship, this article explores the patron-client relationships illustrated in the epistle to the Hebrews seeking biblical principles to guide missionary life and practice.

Elicited Priors For Bayesian Model Specifications In Political Science Research, Jeff Gill, Lee D. Walker

Faculty Publications

We explain how to use elicited priors in Bayesian political science research. These are a form of prior information produced by previous knowledge from structured interviews with subjective area experts who have little or no concern for the statistical aspects of the project. The purpose is to introduce qualitative and area-specific information into an empirical model in a systematic and organized manner in order to produce parsimonious yet realistic implications. Currently, there is no work in political science that articulates elicited priors in a Bayesian specification. We demonstrate the value of the approach by applying elicited priors to a problem …

Petrographic Analysis Of Sherd Samples From The Hot Spring Lake And Airport Sites, Salt Lake City, Utah, Sergio F. Castro-Reino, James R. Allison

Faculty Publications

Prehistoric sherds from two sites near the Salt Lake City airport were analyzed petrographically and compared to a small reference set of sands from the Salt Lake Valley. No Fremont wares are tempered with sand from the Salt Lake area. Some Late Prehistoric wares are tempered with coarse, angular, alluvial sand temper of mineralic composition from metagranite sources 10-12 kilometers away. Volcanic-tempered Late Prehistoric sherds may originate in the Traverse Mountains--provenance cannot be established without further sampling, but the closest sources are at least 30 kilometers away. In all cases sources appear to be non-local to the studied sites.

Pricing In The New Economy: Lessons From The Period Of The E-Commerce Bubble, Phillip J. Bryson

Faculty Publications

The New Economy increased U.S. productivity sharply after 1995. The latest economics literature on the topic, which generally forecasts a secure future for the information economy, is reviewed. The down side of the New Economy were the strategies, especially the pricing strategies of NASDAQ and virtual firms. The critique of Michael Porter regarding the non-strategic price cutting common to those firms is reviewed. Traditional models by Sweezy and Baumol, which focus on pricing in imperfectly competitive industries, are applied to provide a cogent theory as to why those firms made mistakes that were once viewed as common for neophyte industries.

Thorium-Based Thin Films As Highly Reflective Mirrors In The Euv, David D. Allred, William R. Evans, Jed E. Johnson, Richard L. Sandberg, R. Steven Turley

Faculty Publications

As applications for extreme ultraviolet (EUV) radiation have been identified, the demand for better optics has also increased. Thorium and thorium oxide thin films (19 to 61 nm thick) were RF-sputtered and characterized using atomic force microscopy (AFM), spectroscopic ellipsometry, low-angle x-ray diffraction (LAXRD), x-ray photoelectron spectroscopy (XPS), and x-ray absorption near edge structure (XANES) in order to assess their capability as EUV reflectors. Their reflectance and absorption at different energies were also measured and analyzed at the Advanced Light Source in Berkeley. The reflectance of oxidized thorium is reported between 2 and 32 nm at 5, 10, and 15 …

Policing The Border Between Trademarks And Free Speech: Protecting Unauthorized Trademark Use In Expressive Works, Pratheepan Gulasekaram

Faculty Publications

Artists and other creators of expressive works often include trademarks and trademarked products as part of their works. They do so for a number of reasons, including lighthearted humor, critical cultural commentary, parody, or even simply to shock. In instances where such use is both unauthorized by and perceived as disparaging to the mark owner or the trademarked product, owners have attempted to sue under trademark law to enjoin the expressive use. This Article argues that, under a proper analysis of trademark law, precedent, and the free expression ideal enshrined in the First Amendment, mark owners should rarely, if ever, …

Competing Perspectives During Organizational Socialization On The Role Of Certified Athletic Trainers In High School Settings, James M. Mensch, Candice Crews, Murrary F. Mitchell

Faculty Publications

When certified athletic trainers (ATCs) enter a workplace, their potential for professional effectiveness is affected by a number of factors, including the individual's ability to put acquired knowledge, skills, and attitudes into practice. This ability may be influenced by the preconceived attitudes and expectations of athletes, athletes' parents, athletic directors, physical therapists, physicians, and coaches.

Objective: To examine the perspectives of high school coaches and ATCs toward the ATC's role in the high school setting by looking at 3 questions: (1) What are coaches' expectations of ATCs during different phases of a sport season? (2) What do ATCs perceive their …

The Constitutional Failing Of The Anticybersquatting Act, Ned Snow

Faculty Publications

Eminent domain and thought control are occurring in cyberspace. Through the Anticybersquatting Consumer Protection Act (ACPA), the government transfers domain names from domain-name owners to private parties based on the owners' bad-faith intent. The owners receive no just compensation. The private parties who are recipients of the domain names are trademark holders whose trademarks correspond with the domain names. Often the trademark holders have no property rights in those domain names: trademark law only allows mark holders to exclude others from making commercial use of their marks; it does not allow mark holders to reserve the marks for their own …

Data Management And Visualization Of X-Ray Diffraction Spectra From Thin Film Ternary Composition Spreads, I. Takeuchi, C. J. Long, O. O. Famodu, M. Murakami, Jason R. Hattrick-Simpers, G. W. Rubloff, M. Stukowski, K. Rajan

Faculty Publications

We discuss techniques for managing and visualizing x-ray diffraction spectrum data for thin film composition spreads which map large fractions of ternary compositional phase diagrams. An in-house x-ray microdiffractometer is used to obtain spectra from over 500 different compositions on an individual spread. The MATLAB software is used to quickly organize the data and create various plots from which one can quickly grasp different information regarding structural and phase changes across the composition spreads. Such exercises are valuable in rapidly assessing the “overall” picture of the structural evolution across phase diagrams before focusing in on specific composition regions for detailed …

Interphase Exchange Coupling In Fe/Sm-Co Bilayers With Gradient Fe Thickness, Ming-Hui Yu, Jason R. Hattrick-Simpers, Ichiro Takeuchi, Jing Li, Z. L. Wang, J. P. Liu, S. E. Lofland, Somdev Tyagi, J. W. Freeland, D. Giubertoni, M. Bersani, M. Anderle

Faculty Publications

We have fabricated Fe∕Sm–Co bilayers with gradient Fe thicknesses in order to systematically study the dependence of exchange coupling on the thickness of the Fe layer. The Fe layer was deposited at two different temperatures (150 and 300°C) to study the effect of deposition temperature on the exchange coupling. Magneto-optical Kerr effect and x-ray magnetic circular dichroism (XMCD) have been employed as nondestructive rapid characterization tools to map the magnetic properties of the gradient samples. Systematic enhancement in exchange coupling between the soft layer and the hard layer is observed as the soft layer thickness is decreased. Separate exchange couplings …

An Evaluation Of Lidar-Derived Elevation And Terrain Slope In Leaf-Off Conditions, Michael E. Hodgson, John Jensen, George Raber, Jason Tullis, Bruce A. Davis, Gary Thompson, Karen Schuckman

Faculty Publications

The effects of land cover and surface slope on lidar-derived elevation data were examined for a watershed in the piedmont of North Carolina. Lidar data were collected over the study area in a winter (leaf-off) overflight. Survey-grade elevation points (1,225) for six different land cover classes were used as reference points. Root mean squared error (RMSE) for land cover classes ranged from 14.5 cm to 36.1 cm. Land cover with taller canopy vegetation exhibited the largest errors. The largest mean error (36.1 cm RMSE) was in the scrub-shrub cover class. Over the small slope range (0° to 10°) in this …

The Pathogenic Copepod Phrixocephalus Cincinnatus (Copepoda: Pennellidae) In The Eye Of Arrowtooth Flounder, Atherestes Stomias, And Rex Sole, Glyptocephalus Zachirus, From British Columbia, Reginald B. Blaylock, Robin M. Overstreet, A. Morton

Faculty Publications

We report Phrixocephalus cincinnatus, a pennellid copepod infecting the eyes of flatfishes, from a single specimen of rex sole, Glyptocephalus zachirus, for the first time. In the typical host, the arrowtooth flounder, Atherestes stomias, the parasite occurred commonly in sampled populations from the Broughton Archipelago in British. Columbia, infected primarily the right eye of the flounder, and on only one occasion presented more than two parasites per eye. The copepod attached to the choroid layer and ramified throughout the posterior compartment of the eye, resulting in the disruption of the retina and probably impairing host vision. Inflammation and hyperplasia progressed …

Monsoon-Driven Biogeochemical Processes In The Arabian Sea, Jerry D. Wiggert, Raleigh Hood, Karl Banse, John Kindle

Faculty Publications

Although it is nominally a tropical locale, the semiannual wind reversals associated with the Monsoon system of the Arabian Sea result annually in two distinct periods of elevated biological activity. While in both cases monsoonal forcing drives surface layer nutrient enrichment that supports increased rates of primary productivity, fundamentally different entrainment mechanisms are operating in summer (Southwest) and winter (Northeast) Monsoons. Moreover, the intervening intermonsoon periods, during which the region relaxes toward oligotrophic conditions more typical of tropical environments, provide a stark contrast to the dynamic biogeochemical activity of the monsoons. The resulting spatial and temporal variability is great and …
