The "Fair" Triathlon: Equating Standard Deviations Using Bayesian Nonlinear Models, Gilbert W. Fellingham, C. Shane Reese, S. Mckay Curtis

Faculty Publications

The Ironman triathlon was created in 1978 by combining events with the longest distances for races then contested in Hawaii in swimming, cycling, and running. The Half Ironman triathlon was formed using half the distances of each of the events in the Ironman. The Olympic distance triathlon was created by combining events with the longest distances for races sanctioned by the major federations for swimming, cycling, and running. The relative importance of each event in overall race outcome was not given consideration when determining the distances of each of the races in modern triathlons. Thus, there is a general belief …

Interdependency Of Pharmacokinetic Parameters: A Chicken-And-Egg Problem? Not!, Reza Mehvar

Pharmacy Faculty Articles and Research

Pharmacokinetic (PK) software packages are widely used by scientists in different disciplines to estimate PK parameters. However, their use without a clear understanding of physiological parameters affecting the PK parameters and how different PK parameters are related to each other may result in erroneous interpretation of data. Often, mathematical relationships used for the estimation of PK parameters obscure the true physiological relationships among these parameters, prompting a discussion of which parameter came first and giving the appearance of the-chicken-and-the-egg dilemma. In this article, the author attempts to show how different PK parameters are related to physiological parameters and each other …

Conditional Density Operators And The Subjectivity Of Quantum Operations, Matthew S. Leifer

Mathematics, Physics, and Computer Science Faculty Articles and Research

Assuming that quantum states, including pure states, represent subjective degrees of belief rather than objective properties of systems, the question of what other elements of the quantum formalism must also be taken as subjective is addressed. In particular, we ask this of the dynamical aspects of the formalism, such as Hamiltonians and unitary operators. Whilst some operations, such as the update maps corresponding to a complete projective measurement, must be subjective, the situation is not so clear in other cases. Here, it is argued that all trace preserving completely positive maps, including unitary operators, should be regarded as subjective, in …

Labor Struggles, New Social Movements, And America's Favorite Pastime: New York Workers Take On New Era Cap Company, Victoria Carty

Sociology Faculty Articles and Research

Contemporary economic globalization, which is driven and regulated primarily by multinational corporations, has a direct impact on workers' lives. Trade agreements such as the North American Free Trade Agreement (NAFTA) tend to be controlled by corporate interests in the wealthy, industrialized nations. Those countries set the agenda to protect the interests of foreign investors and facilitate the mobility of capital, but they do little to protect the interests of labor. In response, workers in both the global North and South have been forced to rely on their own individual efforts to protect themselves against unfair labor practices. This article presents …

Interventions With Family Caregivers, Jonathan G. Sandberg

Faculty Publications

As a typical self-centered teenager, I struggled to find anything good about grandma moving in with us. Grandma required a lot of help with stairs, dressing, bathing; I noticed this brought a new kind of stress into our home. I think it was particularly hard on my mother, who provided most of the daily care for her mother-in-law. Living in a basement bedroom, I could escape form the stress if I wanted. I did not share a bathroom or hallway, I did not have to listen to incoherent talk and cries in the night as Alzheimer's disease began to take …

The Marriage Moments Program For Couples Transitioning To Parenthood: Divergent Conclusions From Formative And Outcome Evaluation Data, Alan J. Hawkins, Elizabeth B. Fawcett, Jason S. Carroll, Tamara T. Gilliland

Faculty Publications

This article presents the results of a pilot study of the Marriage Moments program, designed to prevent relationship deterioration during the 1st year of parenthood. The self-guided, low-intensity program emphasizes strengthening marital virtues and partnership during this time of significant personal and family transition. One hundred fifty-five married couples participated in a randomized clinical trial with 2 psychoeducational treatment groups (a self-guided group and an instructor-encouraged group) and a comparable control group. Despite positive formative evaluation results from program participants, hierarchical linear modeling analyses failed to find significant Group X Time differences on spouses' reports of marital virtues and a …

Faculty Publications

This research was supported by NASA under STTR contract No. NNA04AA19C to Scientific Systems Company, Inc (SSCI) and Brigham Young University (BYU), and by AFOSR grants F49620-01-1-0091 and F49620-02-C- 0094. The objective of this paper is to explore the feasibility of using multiple low-altitude, short endurance (LASE) unmanned air vehicles (UAVs) to cooperatively monitor and track the propagation of large forest fires. A real-time algorithm for tracking the perimeter of a fire with an on-board infrared sensor is developed. Using this algorithm, we develop a decentralized multiple-UAV approach to monitoring the perimeter of the fire. The UAVs are assumed to …

Of Printers, Prophets, And Politicians: William Lyon Mackenzie, Mormonism, And Early Printing In Upper Canada, Richard Bennett, Daniel H. Olsen

Faculty Publications

Well-known in both Canadian and Latter-day Saint history is the arrival of Charles Ora Card and his faithful band of followers in southern Alberta in 1887. Less explored is the much earlier venture into Upper Canada (Ontario) of such prominent Mormon leaders as Joseph Smith, Brigham Young, Parley P. Pratt, Orson Pratt, Orson Hyde, and scores of others during the 1830s in their concerted attempts to promulgate their new faith on Canadian soil. Their success in converting hundreds of people, many of whom were British- and American-born Methodists or members of other nonconformist faiths, prompted Mormon leaders to send missionaries …

Techniques In The Design Of Thermomechanical Microactuators, Larry L. Howell, Timothy W. Mclain, Michael S. Baker, Christian D. Lott

Faculty Publications

The purpose of this chapter is to provide fundamental background for the design of thermomechanical microactuators. Actuation has been a particularly challenging aspect of microsystem development. Many actuation approaches used at the macro level, such as hydraulics, pneumatics, electric motors, internal combustion engines and turbines, are either too difficult to fabricate at the micro level or do not work well at that scale. Electrostatic attraction is one approach that has been widely used for actuation of microsystems; however, electrostatic actuators tend to have high voltage requirements and low output force capabilities. While electrostatic actuation is suitable for many applications, some …

During 2001-2002, a formal study was conducted jointly by Brigham Young University's Office of Planning and Assessment (OPA) and the Harold B. Lee Library (HBLL) to determine the value of the library to the university community. The study described in this paper was undertaken at a time when some experts were predicting the demise of the academic library, and university administrators were questioning the need for new building, budget, and personnel requests. This paper will present a description of the study and its results, a comparison of similar data collected two years later, and a description of two new student …

Mathematically Modeling The Effects Of Counting Factor (Cf) In Dictyostelium Discoideum, J. C. Dallon, W. Jang, R. H. Gomer

Faculty Publications

Size regulation is a crucial feature in many biological systems, with misregulation leading to dysplasia or hyperplasia. The recent discovery of counting factor (CF) in Dictyostelium discoideum will lead to a greater understanding of how the system regulates the size of a group of cells. In this paper we mathematically model the known effects of CF using two different models: a cellular automata model and a discrete continuum hybrid model. With the use of these models we are able to understand how modulation of adhesion and motile forces by CF can facilitate stream breakup. In addition, the modelling suggests a …

Extending Taylor Plasticity Theory For Microscopic Slip Transfer Conditions, Brent L. Adams, Ray M. Merrill, John A. Basinger, Bassem S. El-Dasher

Faculty Publications

This work was supported primarily by the MRSEC Program of the National Science Foundation under DMR-0079996. Most studies in crystal plasticity are based upon Taylor's original 1938 work. Within Taylor's framework the dependence of yield strength on microstructure, beyond lattice orientation, is carried within the critical resolved shear stress for slip. Thus, as the grain size decreases, the critical resolved shear stress is required to increase. This increase in critical resolved shear stress is applied, uniformly across the entire interior of the slipping grains according to the basic assumption of the model (uniform plastic strain or strain rate). It is …

The Benefits Of A For-Credit Course For New Writing Center Staff, Richard Benjamin Crosby

Faculty Publications

Some questions about writing center theory and praxis never seem to change: how do we prepare for our clientele? How do we engage them? What questions should we ask? When should we direct them? And when should we encourage them to direct us? The list goes on. Fortunately, we consider it a virtue that we continue interrogating the same issues. As students of rhetoric, we realize that the answers to these questions often depend on the contexts in which they are asked. Thus, we give ourselves over to principles of adaptability. Instead of establishing rigid, universal rules that do not …

Unifying Language Modeling Capabilities For Flexible Interaction, Deryle W. Lonsdale, Rebecca Diane Madsen

Faculty Publications

Dialogue processing has taken several different forms in recent years; in this paper we address a cognitive modeling approach to the problem. We begin by sketching some of our work in this area and how it derives from prior research in cognition, modeling, natural language processing, and discourse recipe compilation. We then note that, whereas the complexities of natural language— especially spoken language—have been primarily addressed by technologies that target lower-level linguistic processing, higherlevel processing has been less well studied. We introduce our approach, which is to use an agent-based cognitive modeling architecture for dialogue processing. We mention some of …

Blended Learning Systems Definition, Current Trends, And Future Directions, Charles R. Graham

Faculty Publications

The term blended learning is being used with increased frequency in both academic and corporate circles. In 2003, the American Society for Training and Development identified blended learning as one of the top ten trends to emerge in the knowledge delivery industry (Rooney, 2003). In 2002, the Chronicle of Higher Education quoted the president of Pennsylvania State University as saying that the convergence between online and residential instruction was “the single-greatest unrecognized trend in higher education today” (Young, 2002, p. A33). Also quoted in that article was the editor of the Journal of Asynchronous Learning Networks, who predicted a dramatic …

This paper evaluates the literature and provides current information for IS researchers and instructors focusing on electronic commerce. In this paper, we explore the components of e-credit providers (conventional, person-to-person, and third-party) and explain how each system processes a single transaction. We then analyze several market leaders in each segment and summarize the strengths and weaknesses of each company. We provide guidelines for selecting an e-credit provider and highlight the options that apply best …

Parenting And Peer-Group Behavior In Cultural Context, David A. Nelson, Larry J. Nelson, Criag H. Hart, Chongming Yang, Shenghua Jin

Faculty Publications

Whether specific patterns of parenting are similarly associated with child peer group behavior in diverse cultural contexts has been a fascinating topic of inquiry. From classic anthropological studies dating back to the early twentieth century to the current interest in cross-cultural studies, knowledge concerning the question of universality and cultural variation in parenting linkages to childhood adjustment has expanded at an unprecedented rate (e.g., Harkness & Super, 2002). As the general field of parenting research has uncovered distinctions in parenting styles and practices (e.g., Darling & Steinberg, 1993; hart, Newell, & Olsen, 2003), these concepts have increasingly been applied to …

Nutrient Control Of Microbial Carbon Cycling Along An Ombrotrophicminerotrophic Peatland Gradient, Jason K. Keller, Angela K. Bauers, Scott D. Bridgham, Laurie E. Kellogg, Colleen M. Iversen

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Future climate change and other anthropogenic activities are likely to increase nutrient availability in many peatlands, and it is important to understand how these additional nutrients will influence peatland carbon cycling. We investigated the effects of nitrogen and phosphorus on aerobic CH4 oxidation, anaerobic carbon mineralization (as CO2 and CH4 production), and anaerobic nutrient mineralization in a bog, an intermediate fen, and a rich fen in the Upper Peninsula of Michigan. We utilized a 5-week laboratory nutrient amendment experiment in conjunction with a 6-year field nutrient fertilization experiment to consider how the relative response to nitrogen and phosphorus differed among …

Linking Ligand-Induced Alterations In Androgen Receptor Structure To Differential Gene Expression: A First Step In The Rational Design Of Selective Androgen Receptor Modulators, Dmitri Kazmin, Tatiana Prytkova, C. Edgar Cook, Russell Wolfinger, Tzu-Ming Chu, David Beratan, J. D. Norris, Ching-Yi Chang, Donald P. Mcdonnell

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

We have previously identified a family of novel androgen receptor (AR) ligands that, upon binding, enable AR to adopt structures distinct from that observed in the presence of canonical agonists. In this report, we describe the use of these compounds to establish a relationship between AR structure and biological activity with a view to defining a rational approach with which to identify useful selective AR modulators. To this end, we used combinatorial peptide phage display coupled with molecular dynamic structure analysis to identify the surfaces on AR that are exposed specifically in the presence of selected AR ligands. Subsequently, we …

Defining (Multiple) Selves: Reflections On Fieldwork In Jakarta, Chang Yau Hoon

Research Collection School of Social Sciences

The 'Self' in late-modernity is never singular but multiplies across different discourses, practices and positions. It is constructed through difference. It is only through a relation to the 'Other' that the 'Self' can be defined. This paper endeavours to map the endless negotiations of my 'Self' as male Australian academic of Chinese descent, a Malaysian citizen, a Bruneian resident, and an Indonesian specialist, over a period of fieldwork in Jakarta in 2004. It discusses how I defined my multiple 'Selves' to different individuals and communities, how they in turn defined me, and how these constructions were always shifting. Depending on …
