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 …

The Missing Framework For Virtually Assisted Activities, Jacob Steffen, James Gaskin, Thomas Meservy, Jeffrey Jenkins

Faculty Publications

Various frameworks and taxonomies exist that classify virtual reality (VR), augmented reality (AR), and mixed reality (MR) by their attributes and technical specifications. However, no extant frameworks specifically classify the activities executed with VR and AR devices, which we refer to as virtually assisted activities (VAAs). In the context of past definitions and frameworks of VR and AR, we present a framework for VAAs that examines the underlying motivations for virtualizing some aspect of an activity. By so doing, VAAs are easily compared to similar non-virtualized activities done in physical reality, VR is better compared with AR, and potential benefits …

Partly Cloudy, Scattered Clients: Cloud Implementation In The Federal Government, Elston H. Steele, Indira R. Guzman, James Gaskin, Monica Adya

Faculty Publications

While cloud computing adoption is on the rise, barriers continue to play a critical role in delaying the progress of some cloud computing adoption efforts. In 2010 the United States federal government launched the ‘Cloud First’ policy which requires government agencies to consider the adoption of cloud computing when the solution is secure, reliable and cost effective (Kundra, 2010). Unfortunately, cloud computing adoption among federal agencies has been sluggish. This study investigates pressures asserted to facilitate cloud computing adoption. Although a vast amount of literature exists, very few studies empirically investigate cloud computing adoption from an institutional perspective in concert …

Psychometric Analysis And Validity Of The Daily Alcohol-Related Consequences And Evaluations Measure For Young Adults, Scott A. Baldwin, Christine M. Lee, Jessica M. Cronce, Anne M. Fairlie, David C. Atkins, Megan E. Patrick, Lindsay Zimmerman, Mary E. Larimer, Barbara C. Leigh

Faculty Publications

College students experience a variety of effects resulting from alcohol use and evaluate their experiences on a continuum from negative to positive. Using daily reports collected via cell phone, we examined the psychometric properties of alcohol use consequences and evaluations of those consequences. Participants were 349 undergraduate students (mean age 19.7 [SD = 1.26], 53.4% female). Data were analyzed using a multilevel factor analysis framework, incorporating binary items (consequences) and normally distributed items (evaluations). Our model converged on 2 factors-positive and negative-with similar loadings between- and within-persons. Intraclass correlation coefficients for positive consequences and their evaluations ranged from .30 to …

Schizconnect: Mediating Neuroimaging Databases On Schizophrenia And Related Disorders For Large-Scale Integration, Derin J. Cobia, Lei Wang, Kathryn I. Alpert, Vince D. Calhoun, David B. Keator, Margaret D. King, Alexandr Kogan, Drew Landis, Marcelo Tallis, Matthew D. Turner, Steven G. Potkin, Jessica A. Turner, Jose Luis Ambite

Faculty Publications

SchizConnect (www.schizconnect.org) is built to address the issues of multiple data repositories in schizophrenia neuroimaging studies. It includes a level of mediation—translating across data sources—so that the user can place one query, e.g. for diffusion images from male individuals with schizophrenia, and find out from across participating data sources how many datasets there are, as well as downloading the imaging and related data. The current version handles the Data Usage Agreements across different studies, as well as interpreting database-specific terminologies into a common framework. New data repositories can also be mediated to bring immediate access to existing datasets. Compared with …

Voice And Exit As Accountability Mechanisms: Can Foot-Voting Be Made Safe For The Chinese Communist Party?, Roderick M. Hills Jr., Shitong Qiao

Faculty Scholarship

According to Albert 0. Hirschman's famous dichotomy, citizens can express their preferences with their "voice" (by voting with ballots to elect better representatives) or by "exit" (by voting with their feet to choose better places to live). Suppose, however, that ballot-voting is ineffective: Can exit not merely aid but also replace voice? Using the People's Republic of China, a party state without elective democracy as a case study, we argue that exit is not a substitute for, but rather a complement to, voice. China's bureaucratic promotion system plays the same role that local elections do in the United States, promoting …

Functionality Screens, Christopher Buccafusco, Mark A. Lemley

Faculty Scholarship

Among intellectual property (IP) doctrines, only utility patents should protect function. Utility patents offer strong rights that place constraints on competition, but they only arise when inventors can demonstrate substantial novelty after a costly examination. Copyrights, trademarks, and design patents are much easier to obtain than utility patents, and they often last much longer. Accordingly, to prevent claimants from obtaining “backdoor patents,” the other IP doctrines must screen out functionality. As yet, however, courts and scholars have paid little systematic attention to the ways in which these functionality screens operate across and within IP law.

We have four tasks in …

“Captured Boards”: The Rise Of “Super Directors” And The Case For A Board Suite, Kobi Kastiel, Yaron Nili

Faculty Scholarship

Boards of public corporations in the United States are becoming increasingly independent, due to an effort to ensure that shareholders' interests in the company are protected. Yet, little attention has been given to the way that board members obtain and digest the information necessary for their independent decision-making. In this Article, we highlight how "independent" boards remain extremely dependent on management for the information they need to accomplish their role -- we classify as the "informational capture" of the board. We further describe how activist hedge funds identified this capture and are using what is commonly termed as "super directors" …

Actual Innocence And Wrongful Convictions, Brandon L. Garrett

Faculty Scholarship

In response to wrongful convictions, there has been a revolution in criminal procedure and in research in law and science. Scholars have increasingly studied the characteristics of known wrongful conviction cases and they have conducted interdisciplinary research designed to assess potential changes to procedures used in criminal cases. Scientific bodies have made important recommendations based on this research, and in response, a wide range of jurisdictions have adopted noteworthy changes designed to safeguard crucial types of evidence, such as confession, forensic, and eyewitness evidence, during police investigations and at trial. As a result, both law and science have come together …

Liquidity In Retirement Savings Systems: An International Comparison, John Beshears, James J. Choi, Joshua Hurwitz, David Laibson, Brigitte C. Madrian

Faculty Publications

What is the socially optimal level of liquidity in a retirement savings system? Liquid retirement savings are desirable because liquidity enables agents to flexibly respond to preretirement events that raise the marginal utility of consumption, like income shocks.¹ On the other hand, preretirement liquidity is undesirable when it leads to undersaving arising from, for example, planning mistakes or self- control problems.²

Electric Ion Dispersion As A New Type Of Mass Spectrometer, Michael R. Lindstrom, Iain Moyles, Kevin Ryczko

School of Mathematical & Statistical Sciences Faculty Publications

At the 2014 Fields-MPrime Industrial Problem Solving Workshop, PerkinElmer presented a design problem for mass spectrometry. Traditionally, mass spectrometry is done via three methods: using magnetic fields to deflect charged particles whereby different masses bend differently; using a time-of-flight procedure where particles of different mass arrive at different times at a target; and using an electric quadrupole that filters out all masses except for one very narrow band. The challenge posed in the problem was to come up with a new design for mass spectrometry that did not involve magnetic fields and where mass fractions could be measured in an …

Formed In And Called From The Womb, Dana M. Pike

Faculty Publications

Jeremiah’s call narrative or vocation report includes a clear example of pre-birth divine election:

(1:4) “Now the word of the LORD came to me saying,

(1:5a) ‘Before I formed you in the womb [babbetẹ n] I knew you,

(5b) and before you were born [came forth from the womb/mēreḥem] I consecrated you;

(5c) I appointed you a prophet to the nations’” (Jer. 1:4–5; NRSV).

However, there is ambiguity about the meaning of the phrase “from the womb” and there are persistent questions about the relationship between Jeremiah 1:5a—“Before I formed you in the womb I knew you”—and 1:5b+c, “before you …

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 …

The Consequences Of Audit-Related Earnings Revisions, Jacob Z. Haislip, Linda A. Myers, Susan Scholz, Timothy Seidel

Faculty Publications

In this paper, we investigate the consequences that auditors and their clients face when earnings announced in an unaudited earnings release are subsequently revised, presumably as a result of year-end audit procedures, so that earnings as reported in the 10-K differ from earnings as previously announced. Specifically, we examine whether the likelihood of an auditor ‘losing the client’ is greater following such revisions, and whether the likelihood of dismissal is influenced by revisions that more negatively impact earnings, that cause the client to miss important earnings benchmarks, by greater local auditor competition, or by auditor characteristics. We also examine audit …

Case Teaching And Writing, Peter Ward, Brian Hill

Faculty Publications

College students desire a practitioner-focused education. Case teaching and writing provide more meaningful connections with practitioners and the “real” world than traditional lecture classes. Case teaching is a teaching approach using authentic, challenging, organizational scenarios with unstructured problems requiring students to analyze situations, apply principles, and create solutions through a discussion format. Case teaching provides students with the opportunity to work from the higher-order learning levels of Bloom's Taxonomy and encourages them to challenge their existing mental models, experiment with new ideas, become engaged in the learning process, and reach higher levels of learning. Cases can be taught successfully in …

The Value Of A Master’S Degree To Recreation Professionals, Camilla J. Hodge, Brian J. Hill, Christian Brinton

Faculty Publications

This study assessed the nature of the relationship between earning advanced degrees and career outcomes such as salary, job satisfaction, social capital, and human capital among professionals in the parks and recreation field. The sample (n = 196) was drawn from parks and recreation agencies located in the United States. Agencies, excluding educational institutions, were identified via an Internet search for parks and recreation agencies in urban areas. Findings indicated there was a positive relationship between earning a master’s degree and salary. Earning a master’s degree, however, was not significantly related to job satisfaction, social capital, or human capital. Furthermore, …

Changes In The Timber Industry As A Catalyst For Linguistic Change, Joseph A. Stanley

Faculty Publications

Researchers have noticed the linguistic consequences of major social events in a community. Events that cause dramatic changes in demographics or sudden exposure to a new varieties such as World War II (Bailey et al. 1996), the rapid increase of island tourism (Wolfram, Hazen & Schilling-Estes 1999), or the start of daily trips to the mainland (Schilling 2017) often lead to the rapid spread of innovative linguistic variables and the recession of traditional features (cf. Herold 1990; Johnson 2010). The effects of these “catastrophic events” are typical of external factors in language change (Labov 2001). In this paper, I show …

Axially Uniform Magnetic Field-Modulation Excitation For Electron Paramagnetic Resonance In Rectangular And Cylindrical Cavities By Slot Cutting, Jason Walter Sidabras, James Richie, James S. Hyde

Electrical and Computer Engineering Faculty Research and Publications

In continuous-wave (CW) Electron Paramagnetic Resonance (EPR) a low-frequency time-harmonic magnetic field, called field modulation, is applied parallel to the static magnetic field and incident on the sample. Varying amplitude of the field modulation incident on the sample has consequences on spectral line-shape and line-height over the axis of the sample. Here we present a method of coupling magnetic field into the cavity using slots perpendicular to the sample axis where the slot depths are designed in such a way to produce an axially uniform magnetic field along the sample. Previous literature typically assumes a uniform cross-section and axial excitation …

The Genesis: A Symphonic Work And Analysis, Max Keller

Faculty Publications

The biblical account of creation found in the Book of Genesis is known to billions around the world through its proclamation by multiple religions and numerous denominations. As such it is embedded in many cultures, especially that of the Western civilization and art. This article contains all but two of the movements, three and six, of Max Keller’s analysis of his multi-movement symphonic work The Genesis. The work sought to be a musical expression of the creation narrative found in the Book of Genesis, with direct correlations to the original Hebrew text. As such, the analysis takes an in-depth look …

Measuring Presence: Hypothetical Quantitative Framework, Krzysztof Szczurowski, Matt Smith

Conference papers

Virtual Reality Head - Mounted Display (HMD) manufacturers claim that consumer electronics can finally deliver a high degree of presence in virtual and remote environments. Certainly, current consumer-grade HMD systems offer rich and coherent mediated experiences of such environments. However, the very concept of presence is still a subject of debate, and researchers' investigation of the phenomenon of `presence' is based primarily on qualitative (i.e. questionnaire-based) assessments. Some researchers attempted to develop real-time, quantitative methods to facilitate more objective investigation of presence in mediated environments. Most such methodologies are derived from attempts to correlate presence with cardiovascular and electrodermal activity …

Multiparty Computations In Varying Contexts, Paul Laird, Sarah Jane Delany, Pierpaolo Dondio

Conference papers

Recent developments in the automatic transformation of protocols into Secure Multiparty Computation (SMC) interactions, and the selection of appropriate schemes for their implementation have improved usabililty of SMC. Poor performance along with data leakage or errors caused by coding mistakes and complexity had hindered SMC usability. Previous practice involved integrating the SMC code into the application being designed, and this tight integration meant the code was not reusable without modification. The progress that has been made to date towards the selection of different schemes focuses solely on the two-party paradigm in a static set-up, and does not consider changing contexts. …

Dynamic Behavior Analysis Of Android Applications For Malware Detection, Latika Singh, Markus Hofmann

Conference papers

Android is most popular operating system for smartphones and small devices with 86.6% market share (Chau 2016). Its open source nature makes it more prone to attacks creating a need for malware analysis. Main approaches for detecting malware intents of mobile applications are based on either static analysis or dynamic analysis. In static analysis, apps are inspected for suspicious patterns of code to identify malicious segments. However, several obfuscation techniques are available to provide a guard against such analysis. The dynamic analysis on the other hand is a behavior-based detection method that involves investigating the run-time behavior of the suspicious …

Green Building Business Is Booming, Richard Snow, Mary Snow

Publications

Shelter is one of life’s basic necessities. However, according to the U.S. Department of Energy, residential and commercial buildings account for nearly 40% of the total carbon dioxide (CO2) released in the United States annually [1]. The percentage is even higher in China, which leads the world in CO2 emissions from buildings. Most of this CO2 comes from burning fossil fuels to provide the energy necessary to cool, heat, and light homes, office buildings, and retail space. CO2 emissions from residential and commercials buildings are forecast to increase more than emissions from any other sector over the next 25 years. …

The Power To Wage War Successfully, Matthew C. Waxman

Faculty Scholarship

A century ago and in the midst of American involvement in World War I, future Chief Justice Charles Evans Hughes delivered one of the most influential lectures on the Constitution in wartime. In it he uttered his famous axiom that “the power to wage war is the power to wage war successfully.” That statement continues to echo in modern jurisprudence, though the background and details of the lecture have not previously been explored in detail. Drawing on Hughes’s own research notes, this Article examines his 1917 formulation and shows how Hughes presciently applied it to the most pressing war powers …
