Mennonite Music Education In Southern Manitoba: A Descriptive Study Of Mennonite Collegiate Institute And Steinbach Christian High School, Troy Landon Toavs

Theses and Dissertations

The purpose of this study was to describe and compare the music programs at Mennonite Collegiate Institute (MCI) founded in 1889 and Steinbach Christian High School (SCHS) which has its origins in Steinbach Bible College founded in 1936. The Kanadier, Mennonites who came to Manitoba in 1874 (e.g., Kleine Gemeinde and Bergthaler), had previously rejected part-singing in Russia. However, they became more open to part-singing after they came to Manitoba. The Bergthaler in Gretna helped establish MCI. The Mennonite Brethren (MB) and Evangelical Mennonite Brethren (EMB) were influential in promoting choral music among the Kleine Gemeinde in Steinbach. Steinbach Bible …

Copyright 1992-2012: The Most Significant Development?, Jane C. Ginsburg

Faculty Scholarship

On the occasion of the twentieth anniversary of the Fordham Intellectual Property Law & Policy Conference, its organizer, Professor Hugh Hansen, planned a session on “U.S. Copyright Law: Where Has It Been? Where Is It Going?” and asked me to look back over the twenty years since the conference’s inception in order to identify the most important development in copyright during that period. Of course, the obvious answer is “the Internet,” or “digital media,” whose effect on copyright law has been pervasive. I want to propose a less obvious response, but first acknowledge that digital media and communications have presented …

Machine Speech, Tim Wu

Faculty Scholarship

Computers are making an increasing number of important decisions in our lives. They fly airplanes, navigate traffic, and even recommend books. In the process, computers reason through automated algorithms and constantly send and receive information, sometimes in ways that mimic human expression. When can such communications, called here “algorithmic outputs,” claim First Amendment protection?

The Shale Oil And Gas Revolution, Hydraulic Fracturing, And Water Contamination: A Regulatory Strategy, Thomas W. Merrill, David M. Schizer

Faculty Scholarship

The United States has surpassed Russia as the world's top natural gas producer, and according to the world's most respected energy forecaster, the U.S. will also overtake Saudi Arabia as the largest oil producer by 2020. This surge in U.S. oil and gas production would have seemed wildly improbable a decade ago. It flows from a revolution in U.S. oil and gas production. Energy companies have learned to tap previously inaccessible oil and gas in shale and other impermeable (or "tight") rock formations. To do so, they use "hydraulic fracturing" ("fracturing" or "fracking"), pumping fluid into shale at high pressure …

Diatom Proteomics Reveals Unique Acclimation Strategies To Mitigate Fe Limitation, Brook L. Nunn, Jessica F. Faux, Anna A. Hippman, Maria T. Maldonado, H. Rodger Harvey, David R. Goodlett, Philip W. Boyd, Robert F. Strzepek

OES Faculty Publications

Phytoplankton growth rates are limited by the supply of iron (Fe) in approximately one third of the open ocean, with major implications for carbon dioxide sequestration and carbon (C) biogeochemistry. To date, understanding how alteration of Fe supply changes phytoplankton physiology has focused on traditional metrics such as growth rate, elemental composition, and biophysical measurements such as photosynthetic competence (Fv/Fm). Researchers have subsequently employed transcriptomics to probe relationships between changes in Fe supply and phytoplankton physiology. Recently, studies have investigated longer-term (i.e. following acclimation) responses of phytoplankton to various Fe conditions. In the present study, the coastal diatom, Thalassiosira pseudonana, …

"Children Are Different": Constitutional Values And Justice Policy, Elizabeth S. Scott

Faculty Scholarship

This essay explores the importance for Eighth Amendment jurisprudence and for juvenile crime regulation of Miller v. Alabama (2012) and two earlier Supreme Court opinions rejecting harsh sentences for juveniles. It argues that the Court has broken new ground in defining juveniles as a category of offenders who are subject to special Eighth Amendment protections. In Miller and in Graham v. Florida (2010) particularly, the Court has applied to juveniles' non-capital sentences the rigorous proportionality review that, for adults, has been reserved for death sentences. The essay then turns to the implications of the opinions for juvenile crime policy, arguing …

Perils And Profits: A Reexamination Of The Link Between Profitability And Safety In U.S. Aviation, Peter M. Madsen

Faculty Publications

In many industries, for-profit business organizations make decisions that critically impact the safety of their employees and the public. Managers in such organizations often argue that there is no trade-off between profitability and safety because “safety is good business.” However, prior studies examining the profitability–safety relationship report inconsistent and conflicting results. In the present study, the author reexamines this issue, building on insights into managerial risk taking from the behavioral theory of the firm and hypothesizing that the slope of the profitability–safety relationship reaches an inflection point at the organizational profitability aspiration. Using data from the U.S. airline industry, the …

Time-Dependent Deposition Characteristics Of Fine Coal Fly Ash In A Laboratory Gas Turbine Environment, Robert Laycock, Thomas H. Fletcher

Faculty Publications

Time-dependent deposition characteristics of fine coal fly ash were measured in the Turbine Accelerated Deposition Facility (TADF) at Brigham Young University. Two samples of subbituminous coal fly ash, with mass mean diameters of 3 and 13 microns, were entrained in a hot gas flow with a gas temperature of 1288 C and Mach number of 0.25. A nickel-based, superalloy metal coupon approximately 0.3 cm thick was held in a hot particle-laden gas stream to simulate deposition in a gas turbine. Tests were conducted with deposition times of 20, 40, and 60 min. Capture efficiencies and surface roughness characteristics (e.g., Ra) …

Cluster Ensemble-Based Image Segmentation, Xiaoru Wang, Junping Du, Shuzhe Wu, Xu Li, Fu Lo

Electrical and Computer Engineering Faculty Publications and Presentations

Image segmentation is the foundation of computer vision applications. In this paper, we propose a new cluster ensemble-based image segmentation algorithm, which overcomes several problems of traditional methods. We make two main contributions in this paper. First, we introduce the cluster ensemble concept to fuse the segmentation results from different types of visual features effectively, which can deliver a better final result and achieve a much more stable performance for broad categories of images. Second, we exploit the PageRank idea from Internet applications and apply it to the image segmentation task. This can improve the final segmentation results by combining …

A Transformation-Based Approach To Implication Of Gste Assertion Graphs, Gouwu Yang, William N. N. Hung, Xiaoyu Song, Wensheng Guo

Electrical and Computer Engineering Faculty Publications and Presentations

Generalized symbolic trajectory evaluation (GSTE) is a model checking approach and has successfully demonstrated its powerful capacity in formal verification of VLSI systems. GSTE is an extension of symbolic trajectory evaluation (STE) to the model checking of -regular properties. It is an alternative to classical model checking algorithms where properties are specified as finite-state automata. In GSTE, properties are specified as assertion graphs, which are labeled directed graphs where each edge is labeled with two labeling functions: antecedent and consequent. In this paper, we show the complement relation between GSTE assertion graphs and finite-state automata with the expressiveness of regular …

Awareness At A Threshold: Urban Exchange Through Public Space, Matthew Spears

Architecture Theses and Projects

The moment of arrival becomes an important opportunity for cultural exchange in an urban environment. This exchange can be both the physical exchange between two places or it can be the experiential exchange between two or more disparate groups. These moments of exchange are an elusive experience for visitors as well as residents and are easily forgotten. Expressing the space of the traveler, an interactive space between locals and visitors, can raise cultural awareness between the most prominent groups as well as the marginalized groups, creating a more cohesive urban imaginary. The major exchange hub in Seattle, Washington speaks to …

Cell Speed Is Independent Of Force In A Mathematical Model Of Amoeboidal Cell Motion With Random Switching Terms., J. C. Dallon, Emily J. Evans, Christopher Grant, William V. Smith

Faculty Publications

In this paper the motion of a single cell is modeled as a nucleus and multiple integrin based adhesion sites. Numerical simulations and analysis of the model indicate that when the stochastic nature of the adhesion sites is a memoryless and force independent random process, the cell speed is independent of the force these adhesion sites exert on the cell. Furthermore, understanding the dynamics of the attachment and detachment of the adhesion sites is key to predicting cell speed. We introduce a differential equation describing the cell motion and then introduce a conjecture about the expected drift of the cell, …

Broadband Fourier Transform Rotational Spectroscopy For Structure Determination: The Water Heptamer, Cristóbal Pérez, Simon Lobsiger, Nathan A. Seifert, Daniel P. Zaleski, Berhane Temelso, George C. Shields, Zbigniew Kisiel, Brooks H. Pate

Faculty Journal Articles

Over the recent years chirped-pulse, Fourier-transform microwave (CP-FTMW) spectrometers have chan- ged the scope of rotational spectroscopy. The broad frequency and large dynamic range make possible structural determinations in molecular systems of increasingly larger size from measurements of heavy atom (¹³C, ¹⁵N, ¹⁸O) isotopes recorded in natural abundance in the same spectrum as that of the parent isotopic species. The design of a broadband spectrometer operating in the 2–8 GHz frequency range with further improvements in sensitivity is presented. The current CP-FTMW spectrometer performance is benchmarked in the analyses of the rotational spectrum of the water …

Four Questions About Fracking, Thomas W. Merrill

Faculty Scholarship

It is difficult to think of a more timely or important topic than horizontal hydraulic fracturing and its impact on the environment. It is especially useful to have an exchange of views on this subject now, before the statutes, regulations, and court decisions start to roll in. Law professors – I cannot speak for anyone else – have a strong proclivity for backward-looking analysis, dissecting what should have been done after the basic direction of the law is set and the courts have spoken. It is much more useful to weigh the pros and cons of different approaches at an …

Representing The Agent Through Second-Order States, David A. Jensen

Faculty Publications

Some recent views of action have claimed that a correct conceptual account of action must include second-order motivational states. This follows from the fact that first-order motivational states such as desires account for action or mere behavior in which the agent’s participation is lacking; thus, first-order motivational states cannot by themselves account for action in which the agent participates, so-called full-blooded action. I argue that representing the agent’s participation by means of second-order states is bound to fail because it misrepresents what an agent is doing when acting in the full-blooded sense. I begin by characterizing full-blooded action and explaining …

Rotor Bar Fault Monitoring Method Based On Analysis Of Air-Gap Torques Of Induction Motors, Aderiano Da Silva, Nabeel Demerdash, Richard J. Povinelli

Electrical and Computer Engineering Faculty Research and Publications

A robust method to monitor the operating conditions of induction motors is presented. This method utilizes the data analysis of the air-gap torque profile in conjunction with a Bayesian classifier to determine the operating condition of an induction motor as either healthy or faulty. This method is trained offline with datasets generated either from an induction motor modeled by a time-stepping finite-element (TSFE) method or experimental data. This method can effectively monitor the operating conditions of induction motors that are different in frame/class, ratings, or design from the motor used in the training stage. Such differences can include the level …

Effect Of Hydrodynamic Force On Microcantilever Vibrations: Applications To Liquid-Phase Chemical Sensing, I. Dufour, E. Lemaire, B. Caillard, H. Debeda, C. Lucat, Stephen M. Heinrich, Fabien Josse, O. Brand

Electrical and Computer Engineering Faculty Research and Publications

At the microscale, cantilever vibrations depend not only on the microstructure’s properties and geometry but also on the properties of the surrounding medium. In fact, when a microcantilever vibrates in a fluid, the fluid offers resistance to the motion of the beam. The study of the influence of the hydrodynamic force on the microcantilever’s vibrational spectrum can be used to either (1) optimize the use of microcantilevers for chemical detection in liquid media or (2) extract the mechanical properties of the fluid. The classical method for application (1) in gas is to operate the microcantilever in the dynamic transverse bending …

Photocatalytic Degradation Of Nox By Concrete Pavement Containing Tio₂, Joel K. Sikkema

Faculty Work Comprehensive List

Emissions from motor vehicles cause the concentrations of nitrogen oxides (NOX) in the immediate vicinity of highways to be 30-100% higher than background concentrations. Photocatalytic pavements have been proposed to address this localized pollution problem. Bench-scale evaluation of environmental variables confirmed that nitric oxide (NO) oxidation rate positively correlated with influent NO concentration and irradiance and negatively correlated with relative humidity. However, comparison of the slope of these correlations found significant differences between this study and other published work. Slab water loss, a variable not investigated in prior work, positively correlated with NO oxidation rate at water losses of 0-2% …

Allied Health Evaluation Review: Practice And Education Infrastructure, Mardi Lowe-Heistad, Sandra Lowe

Internet Journal of Allied Health Sciences and Practice

The Allied Health Evaluation Review: Practice and Education Infrastructure was a detailed review of the practice progress of twenty-seven allied health professions. The key objectives of the evaluation review were to determine each profession’s practice status, measured on a common set of parameters that could be compared to one another at a given point in time, and to identify what variables, if any, were correlated with the practice progress of a given profession. Practice benchmarks were established and tools were developed to measure the practice progress of each profession relative to the others at a given point in time. The …

Nuclear Translocation Of Cardiac G Protein-Coupled Receptor Kinase 5 Downstream Of Select Gq-Activating Hypertrophic Ligands Is A Calmodulin-Dependent Process., Jessica I Gold, Jeffrey S Martini, Jonathan Hullmann, Erhe Gao, J Kurt Chuprun, Linda Lee, Douglas G Tilley, Joseph E Rabinowitz, Julie Bossuyt, Donald M Bers, Walter J. Koch

Department of Medicine Faculty Papers

G protein-Coupled Receptors (GPCRs) kinases (GRKs) play a crucial role in regulating cardiac hypertrophy. Recent data from our lab has shown that, following ventricular pressure overload, GRK5, a primary cardiac GRK, facilitates maladaptive myocyte growth via novel nuclear localization. In the nucleus, GRK5's newly discovered kinase activity on histone deacetylase 5 induces hypertrophic gene transcription. The mechanisms governing the nuclear targeting of GRK5 are unknown. We report here that GRK5 nuclear accumulation is dependent on Ca(2+)/calmodulin (CaM) binding to a specific site within the amino terminus of GRK5 and this interaction occurs after selective activation of hypertrophic Gq-coupled receptors. Stimulation …

Crew Training Requirements For Long Duration Missions, Ann Wargetz

Theses and Dissertations

After reviewing the journals of astronauts, cosmonauts, and others who lived and worked in confinement, a new pre-mission training approach for missions in confinement was developed. This new training approach is founded on the idea that conflicts in confinement often arise due to humanity's propensity to focus on how others behave rather than our own behavior. After reviewing the stresses experienced during spaceflight and astronaut training and selection methods, a survey was written and distributed to researchers with experience living and working in confined environments. The questions sought to discover whether conflicts arise for these reasons based on the participant's …

Efficient Regeneration Of Chemical Solvents For Carbon Dioxide Capture By Polymeric Membrane Contactors, Xuefei Zhang

Theses and Dissertations

Although extensive research attention has been drawn to using membranes for carbon dioxide (CO2) capture from flue gas, the use of membranes for stripping CO2 solvents has rarely been studied. The technical feasibility of using polymeric membrane based separation technology to recover CO2 from CO2 saturated chemical solvents such as monoethanolamine is investigated in the present research. A membrane system was built to study the performance of several common polymeric porous membranes for the recovery of CO2 from saturated aqueous MEA solution by the thermal swing process. The stripped CO2 gas was swept by mass flow controlled N2 reference gas …

Characterization Of Phosphorus, Nitrogen, And Sulfur Concentrations In A Paired Disturbed And Natural Wetland In Northwest Minnesota, Nicolas Buer

Theses and Dissertations

A degraded wetland with a history of human-induced hydrologic alterations lies within northwestern Minnesota's Skull Lake Wildlife Management Area (WMA). Although conservation practices have been enacted by the Minnesota Department of Natural Resources (MNDNR), there remains interest in the wetland's potential for ecological restoration. Restoration should not be undertaken without an understanding of underlying factors leading to degradation. A paired study between the disturbed wetland at Skull Lake WMA and the relatively natural wetland in the nearby Caribou WMA was designed to help understand near surface pore water geochemistry in an effort to determine causes of degradation and the potential …

Analytical studies are limited to those which have examined …

Mechanical Characterization Of Composite Repairs For Fiber-Glass Wind Turbine Blades, Tanveer Singh Chawla

Theses and Dissertations

While in service, wind turbine blades experience various modes of loading. An example is impact loading in the form of hail or bird strikes, which might lead to localized damage or formation of cracks a few plies deep on the blade surface. One of the methods to conduct repairs on wind turbine blades that are damaged while in service is hand lay-up of the repair part after grinding out the damaged portion and some of its surrounding area. The resin used for such repairs usually differs from the parent plate resin in composition and properties such as gel time, viscosity, …
