Determination Of Curve Number And Estimation Of Runoff Using Indian Experimental Rainfall And Runoff Data

Journal of Spatial Hydrology

The Curve Number (CN) method has been widely used to estimate runoff from rainfall runoff events. In this study, experimental plots in Roorkee, India have been used to measure natural rainfall-driven rates of runoff under the main crops found in the region and derive associated CN values from the measured data using five different statistical methods. CNs obtained from the standard United States Department of Agriculture - Natural Resources Conservation Service (USDA-NRCS) table were suitable to estimate runoff for bare soil, soybeans and sugarcane. However, we propose a new method to estimate CN values from measured rainfall-runoff data (CN calibrated) …

A Dream, A Rock, And A Pillar Of Fire, Adam S. Miller

Maxwell Institute Publications

The first chapter of 1 Nephi may be the most read in all of Mormon scripture. But beyond its veneer of familiarity, its substance remains shadowed by a host of contextual and theological questions. The papers collected in this volume offer theological readings that draw on careful examinations of 1 Nephi 1’s structure and literary details to explore questions about Lehi’s world, the nature of revelation, the problem of suffering, and the promised Messiah.

Opportunity Lost, Brian C. Hales

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

The Ghost of Eternal Polygamy boldly declares “that plural marriage never was — is not now — and never will be ordained of God” (21) and that the Mormon religion is guilty of “extraordinary spiritual abuse” (22) due to the practice. Seven distinct problems associated with plural marriage are identified, four of which have merit: polygamy history is often messy; earthly polygamy is unfair to women; widows and widowers are treated differently regarding future sealings; and the cancellation of sealings has not always paralleled the desires of the participants. Three additional issues form the bulk of the discussion and are …

Why Control Of Pro In Rationale Clauses Is Not A Relation Between Arguments, Alexander Williams, Jeffrey Jack Green

Faculty Publications

After (1) or (2) we can use (3), a rationale clause, to mean (4). We then mean that those who acquire a pitcher are the traders of the outfielders.

(1) The team traded away two outfielders

(2) Two outfielders were traded away

(3) PRO to acquire a pitcher.

(4) because then the trader might acquire a pitcher.

On grammatical accounts, this indicates a relation between two arguments that ensures their coreference, for any assignment of values to variables. PRO in (3), for example, would be related in this way to an argument that is linked to the role of …

The Higher-Ed Organizational-Scholar Tension: How Scholarship Compatibility And The Alignment Of Organizational And Faculty Skills, Values And Support Affects Scholar’S Performance And Well-Being, Milagros Pereyra-Rojas, Enrique Mu, James Gaskin, Tony Lingham

Faculty Publications

Scholars and institutions alike are concerned with academic productivity. Scholars not only further knowledge in their professional fields, they also bring visibility and prestige to themselves and their institutions, which in turn attracts research grants and more qualified faculty and graduate students. Many studies have been done on scholar productivity, and many of them focus on individual factors such as gender, marital status, and individual psychological characteristics. Also, a few studies are concerned about scholars’ well-being. We propose a causal model that considers the compatibility of the scholarship dimensions valued by scholars and institutions and their academic alignment with actual …

Functional And Mechanistic Insight Into The Role Of Atg9a In Autophagy, Vajira Kaushalya Weerasekara

Theses and Dissertations

The bulk degradative process of macroautophagy requires the dynamic growth of autophagosomes, which carry cellular contents to the lysosome for recycling. Atg9A, a multi-pass transmembrane protein, is an apical regulator of autophagosome growth, yet its regulatory mechanism remains unclear. Our work suggests that hypoxia (low glucose and oxygen) triggers a rearrangement of the small adapter protein 14-3-3ζ interactome. Our data suggest that the localization of mammalian Atg9A to autophagosomes requires phosphorylation on the C terminus of Atg9A at S761, which creates a 14-3-3z docking site. Under basal conditions, this phosphorylation is maintained at a low level and is dependent on …

"I Can Physically Feel The Difference": Exploring Physicalizations Of Running Data, Zann Benjamin Anderson

Theses and Dissertations

We explore user interactions with concrete physical visualizations—physicalizations—of personal experiential data. We conducted three user studies involving physicalizations of data gathered while trail running—a sport in which participants are largely more focused on the experience than the exercise itself. In two qualitative studies, we asked trail runners to give us a GPS path from a "significant run" and then prepared a 3D physicalization featuring the path overlaid as a raised line on the corresponding real-world terrain. In the first, physicalizations had a significant impact in helping participants recall memories of their experiences, and participants shared many stories. In a follow-up …

A Semi-Automatic Grading Experience For Digital Ink Quizzes, Brooke Ellen Rhees

Theses and Dissertations

Teachers who want to assess student learning and provide quality feedback are faced with a challenge when trying to grade assignments quickly. There is currently no system which will provide both a fast-to-grade quiz and a rich testing experience. Previous attempts to speed up grading time include NLP-based text analysis to automate grading and scanning in documents for manual grading with recyclable feedback. However, automated NLP systems all focus solely on text-based problems, and manual grading is still linear in the number of students. Machine learning algorithms exist which can interactively train a computer quickly classify digital ink strokes. We …

Scriptures With Pictures: Methodology, Unexamined Assumptions, And The Study Of The Book Of Abraham, Mark J. Johnson

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

Research on the origins and nature of the Book of Abraham and the accompanying facsimiles has long been hampered by faulty methodology. And while the last few years have seen a significant reexamination of the assumptions that represent the underpinning of our understandings of the Book of Abraham, some unexamined assumptions persist. This study addresses seven aspects of the Book of Abraham, which include a discussion of the sources, the process, the results, the content, the witnesses, and the historical background. For each of these aspects, this study identifies lingering assumptions and shows how a proper methodology can validate or …

"What Is It About This Place?": Truman Madsen, Religious Education, And The Mission Of Byu, Bruce C. Hafen

BYU Studies

Barnard (“Barney”) Madsen has written a readable, thoughtful, and well-informed biography about his charismatic father, Truman Madsen. Although Truman didn’t keep a conventional journal, he maintained “journal files”—“crucial journal entries or documents he preserved for his posterity.” Those files, along with Barney’s intimate and observant relationship with his father, have now yielded rich biographical resources.

Ideas About Nature In American Art And Visual Culture, Mark Graham

Faculty Publications

The stories we tell ourselves about nature deeply influence how we attempt to preserve, use, or restore nature as well as practices of art and art education that are concerned with ecological issues (Cronon 1996). Landscapes are culture before they are nature (Schama 1996). Yet, our ideas about wilderness, nature, landscape, and sustainability are fraught with paradox and debate. For example, Darwin’s fundamental assertions about the human relationship to nature continue to spark theological, political and educational controversies. Some environmentalists caution that our consumerist economy will destroy the planet and that we need to return to a less sophisticated technology …

Neural Networks In Strategic Marketing: Exploring The Possibilities, Kristen Bell Detienne, David H. Detienne

Faculty Publications

A review of the literature indicates that few studies have used artificial neural networks (ANNs) for data analysis in business and marketing research, even though there are many benefits to the use of ANNs. Therefore, this article discusses neural networks (NNs) that can be used in addition to or as an alternative to linear regression for data analysis in strategic marketing. The function and layout of NNs make them ideal for research dealing with nonlinear, incomplete, unspecified, or ‘fuzzy’ data and offer several advantages over linear regression. Unfortunately, in many marketing studies, the information being modeled is far from flawless …

Understanding “It Depends” In Organizational Research: A Theory-Based Taxonomy, Review, And Future Research Agenda Concerning Interactive And Quadratic Relationships, Richard G. Gardner, T. Brad Harris, Ning Li, Bradley L. Kirkman, John E. Mathieu

Faculty Publications

The study of interaction effects is critical for creating, extending, and bounding theory in organizational research. Integrating and extending prior work, we present a taxonomy of two-way interaction effects that can guide organizational scholars toward clearer, more precise ways of developing theory, advancing hypotheses, and interpreting results. Specifically, we identify three primary interaction types, including strengthening, weakening, and reversing effects. In addition, we explore subcategories within these interaction types. Our review of articles published in leading management and applied psychology journals from 2009 to 2013 supports the generalizability of this framework. We offer specific recommendations for using this taxonomy to …

Optimal Combined Long-Term Facility Design And Short-Term Operational Strategy For Chp Capacity Investments, Jose Mojica, Damon Petersen, Brigham Hansen, Kody Powell, John Hedengren

Faculty Publications

This work presents a detailed case study for the optimization of the expansion of a district energy system evaluating the investment decision timing, type of capacity expansion, and fine-scale operational modes. The study develops an optimization framework to find the investment schedule over 30 years with options of investing in traditional heating sources (boilers) or a next-generation combined heat and power (CHP) plant that provides heat and electricity. In district energy systems, the selected capacity and type of system is dependent on demand-side requirements, energy prices, and environmental costs. This work formulates capacity planning over a time horizon as a …

Student Voices For Why College Students Take Physical Activity Classes When It Is Not Required For Graduation, David C. Barney, Kelsey Higginson

Faculty Publications

The time in college is a time to prepare to go out into the world and be a contributing member of society. Typically, a college education should take four years to complete. Many colleges are eliminating the physical activity requirement for graduation, hoping that it will aid the student in graduating in a timely manner. Yet, students still take physical activity classes while working towards graduation. For this study, 420 college students (235 males & 185 females) participated in this study. Students in physical activity classes at a private university of the western United States completed a survey in regards …

Developing A General Methodology For Evaluating Composite Action In Insulated Wall Panels, Taylor Sorensen

Faculty Publications

Precast concrete sandwich wall panels (PCSWPs) have been in use for over 60 years. They provide a very efficient building envelope for many buildings. Characteristic PCSWPs comprise an outer and inner layer (or wythe) of concrete separated by an insulating material. To use all of the material as efficiently as possible, the layers are attached by connectors which penetrate through the insulating layer and are embedded in either concrete wythe. These connectors make it possible for both layers of the wall to work together when resisting loads. The connectors are made out of plastic, or FRP, to prevent heat transfer …

A Continuous Time Model Of Centrally Controlled Motion With Random Switching Terms, J. C. Dallon, L C. Despain, E J. Evans, C P. Grant, Willaim V. Smith

Faculty Publications

This paper considers differential problems with random switching, with specific applications to the motion of cells and centrally coordinated motion. Starting with a differential-equation model of cell motion that was proposed previously, we set the relaxation time to zero and consider the simpler model that results. We prove that this model is well-posed, in the sense that it corresponds to a pure jump-type continuous time Markov process (without explosion). We then describe the model's long-time behavior, first by specifying an attracting steady-state distribution for a projection of the model, then by examining the expected location of the cell center when …

Modeling Effects Of Annealing On Coal Char Reactivity To O2 And Co2, Based On Preparation Conditions, Troy Michael Holland, Sham Bhat, Peter Marcy, James Gattiker, Joel D. Kress, Thomas H. Fletcher

Faculty Publications

Oxy-fired coal combustion is a promising potential carbon capture technology. Predictive computational fluid dynamics (CFD) simulations are valuable tools in evaluating and deploying oxyfuel and other carbon capture technologies, either as retrofit technologies or for new construction. However, accurate predictive combustor simulations require physically realistic submodels with low computational requirements. A recent sensitivity analysis of a detailed char conversion model (Char Conversion Kinetics (CCK)) found thermal annealing to be an extremely sensitive submodel. In the present work, further analysis of the previous annealing model revealed significant disagreement with numerous datasets from experiments performed after that annealing model was developed. The …

Modeling Soot Oxidation And Gasification With Bayesian Statistics, Alexander Jon Josephson, Neal D. Gaffin, Sean T. Smith, Thomas H. Fletcher, David Lignell

Faculty Publications

This paper presents a statistical method for model calibration using data collected from literature. The method is used to calibrate parameters for global models of soot consumption in combustion systems. This consumption is broken into two different submodels: first for oxidation where soot particles are attacked by certain oxidizing agents; second for gasification where soot particles are attacked by H2O or CO2 molecules. Rate data were collected from 19 studies in the literature and evaluated using Bayesian statistics to calibrate the model parameters. Bayesian statistics are valued in their ability to quantify uncertainty in modeling. The calibrated consumption model with …

The Perception And Production Of Two Vowel Mergers In Cowlitz County, Washington, Joseph A. Stanley

Faculty Publications

Recent literature has revealed ongoing variation in Pacific Northwest English. In particular, back vowels (cf. Ward 2003; Becker et al. 2013; McLarty & Kendall 2014) and pre-velar front vowels (cf. Wassink et al. 2009; Riebold 2015; 2015, and others) have received considerable attention. In this paper I present recent data from Cowlitz County, Washington that shed light other mergers involving these vowels.

As explained in the Atlas of North American English (Labov, Ash & Boberg 2006), some form of the conditioned merger of /e, ɛ, æ/ before intervocalic /r/, sometimes known as the Mary-merrymarry merger, is found in most varieties …

A Comparative Discourse Analysis Of Spanish Past Narrations From The Actfl Opi And Opic, Alan V. Brown, Troy L. Cox, Gregory L. Thompson

Faculty Publications

The ACTFL Oral Proficiency Interview (OPI) and accompanying proficiency guidelines have become a mainstay in academic foreign language assessment. In 2006, an asynchronous electronic interface of the OPI was made available in which candidates are asked to record themselves responding to questions delivered aurally via computer, labeled the Oral Proficiency Interview-computer (OPIc). Thompson, Cox, and Knapp (2016) found that both instruments produced similar results but that many students in their sample who scored at the Advanced Low level on the traditional OPI scored one sublevel higher on the OPIc. The primary objective of the present study is to analyze lexical …

The Impact Of Shadow It Systems On Perceived Information Credibility And Managerial Decision Making, Noah Myers, Matthew Starliper, Scott L. Summers, David A. Wood

Faculty Publications

Business trends show that more and more employees are creating shadow IT systems—IT systems that are not sanctioned or monitored by the IT department. This paper examines how the use of shadow IT in product costing impacts managers’ perceptions of information credibility and managerial decision-making. Using two experiments, we find that participants view information from shadow IT systems as less credible and they are less impacted by and less willing to rely on costing reports produced from shadow IT systems versus non-shadow IT systems. We also find that although participants are concerned about the credibility of shadow IT systems, they …

The Effects Of Gamification On Corporate Compliance Training: A Field Experiment Of True Office Anti-Corruption Training Programs, Ryan J. Baxter, D. Kip Holderness, David A. Wood

Faculty Publications

Companies rely on internal controls to comply with the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act. One such control is anti-corruption employee training. Although corporate training is a key component of anti-fraud policies and procedures, it is often perceived as dull by employees. To motivate greater engagement, firms are experimenting with training that involves elements of digital games, known as gamification. We perform a field experiment with 158 employees of a large, multinational bank to examine the effectiveness of gamified anticorruption training. We find that employees strongly prefer gamified training to traditional, nongamified training and that gamified …

A Video-Based Screening System For Automated Risk Assessment Using Nuanced Facial Features, Steven J. Pentland, Nathan W. Twyman, Judee K. Burgoon, Jay F. Nunamaker, Christopher B.R. Diller

Faculty Publications

This study investigates the development of an automated interviewing system that uses facial behavior as an indicator of the risk of given illicit behavior. Traditional facial emotion indicators of risk in semistructured dialogue may have limitations in an automated approach. However, an initial analysis of mock crime interviews suggests that the face may exhibit some form of rigidity during highly structured interviews. An interviewing system design using facial rigidity analysis was implemented and experimentally evaluated, the results of which further reveal that the rigidity is fairly generalized across the face. Whereas existing theory traditionally focuses on leakage of facial expressions, …

Gradient-Based Optimization Of Wind Farms With Different Turbine Heights, Andrew P.J. Stanley, Jared Thomas, Andrew Ning, Jennifer Annoni, Katherine Dykes, Paul Fleming

Faculty Publications

Turbine wakes reduce power production in a wind farm. Current wind farms are gen- erally built with turbines that are all the same height, but if wind farms included turbines with different tower heights, the cost of energy (COE) may be reduced. We used gradient-based optimization to demonstrate a method to optimize wind farms with varied hub heights. Our study includes a modified version of the FLORIS wake model that accommodates three-dimensional wakes integrated with a tower structural model. Our purpose was to design a process to minimize the COE of a wind farm through layout optimization and varying turbine …

Behavioral Ecology Of American Pikas (Ochotona Princeps) At Mono Craters, California: Living On The Edge, Andrew T. Smith, John D. Nagy, Constance I. Millar

Western North American Naturalist

The behavioral ecology of the American pika (Ochotona princeps) was investigated at a relatively hot south-facing, low-elevation site in the Mono Craters, California, a habitat quite different from the upper montane regions more typically inhabited by this species and where most prior investigations have been conducted. Mono Craters pikas exhibited a behavioral profile that contrasted significantly with that of pikas found in upper montane regions. Mono Craters pikas were less surface active than pikas in studies at high-elevation sites, although their rate of short-call vocalizations was similar. Mono Craters pikas did not exhibit typical foraging behavior: they fed …

Development Of A Stream Water Temperature Model As A Component Model For Openmi Based Integrated Modelling Of River Zenne, Belgium., Narayan Kumar Shrestha, Olkeba Tolessa Leta, Jiri Nossent, Ann Van Griensven, Willy Bauwens

Open Water Journal

In 2000, the European Union launched the Water Framework Directive (WFD) (EU, 2000), which calls to achieve a good ecological status of all water bodies by 2015 through integrated river basin management. Integrated models are therefore necessary to serve as tools for river basin management in the scope of the WFD. Despite large investments made for the management of the Brussels’ sewer systems, the Zenne river still receives high loads of pollutants, especially considering the small size of this receiving water body. An interuniversity, multidisciplinary research project ‘Good Ecological Status of the river Zenne (GESZ)’ was therefore launched to evaluate …
