The Changing Moral Mirror Of Society: From Human To Artifical Intelligent Systems, Gary Langford, Teresa Langford

Engineering and Technology Management Faculty Publications and Presentations

Management of technology and its development carry along the responsibility and consequences for interactions between Human and Artificial Intelligent Systems (AIS). In spite of all good intentions, the effects and repercussions of conflicts between Human and the systems built with intent to assist Human may be proceeding along the path that will recognize a dismal mistake in judgment. Dreadful and intolerable impositions on Human behavior may arise regardless of how AIS is designed. That is not to say progress should cease, but rather to make the case that intensely determined efforts need to delve into the uses and implications of …

Building A Sustainable Business Model Through Technology Entrepreneurship: An Analysis Of Business Models From A System And A System Of Systems Perspective, Gary Langford, Teresa Langford

Engineering and Technology Management Faculty Publications and Presentations

Case study methods are used to identify key elements of business models in highly competitive environments. Small businesses, in particular, must rely on entrepreneurial prowess and innovation, adapt to their environment, have sufficient resources, and skillfully manage project outcomes in entrepreneurial start-up situations. This research hypothesized that a problem faced by entrepreneurial organizations is due to the fundamental flaws and poor adaptability of their business models to satisfy needs of customers and prospective customers. The problem is that the flow of value from business to customer was different from the flow of value from business to user. Two kinds of …

Domain Process Model Overcome Limitations Of Engineering Models For Developing Artificial Intelligent Systems, Gary O. Langford, John Green, Daniel P. Burns, Alexander Keller, Dean C. Schmidt

Engineering and Technology Management Faculty Publications and Presentations

The integrated set of prognostic domains (ISPD) of technology presented here provides a normative means to construct a wholly new process model for guiding Technology Management of Artificial Intelligent Systems (AIS). Seventeen domains represent all-inclusive stakeholder perspectives that encapsulate lifecycle analyses, evaluations, feasibilities, and tradeoffs with the domain contexts. Following Systems Model-Based thinking (SMBT), a postulated focal point interaction is the entry condition from which each domain is considered and thereafter traversed. Domains are interactive with each other through concurrent, iterative, recursive, and non-recursive processes. This interactive work continues until the completion milestones of each domain are satisfied. Techniques such …

New Perspectives On The Schrödinger-Pauli Theory Of Electrons: Part Ii: Application To The Triplet State Of A Quantum Dot In A Magnetic Field, Marlina Slamet, Viraht Sahni

Publications and Research

The Schrödinger-Pauli (SP) theory of electrons in the presence of a static electromagnetic field can be described from the perspective of the individual electron via its equation of motion or 'Quantal Newtonian' first law. The law is in terms of 'classical' fields whose sources are quantum-mechanical expectation values of Hermitian operators taken with respect to the wave function. The law states that the sum of the external and internal fields experienced by each electron vanishes. The external field is the sum of the binding electrostatic and Lorentz fields. The internal field is the sum of fields representative of properties of …

These predictions, valid for the LHC operating at 13 TeV, include without any approximation all the NLO electroweak and QCD contributions of O(αⁱ_sα^j+1) with i + j = 2, 3. In addition, the predictions presented here improve upon the NLO QCD results by adding the effects of soft gluon emission …

Measuring The Weizsäcker-Williams Distribution Of Linearly Polarized Gluons At An Electron-Ion Collider Through Dijet Azimuthal Asymmetries, Adrian Dumitru, Vladimir Skokov, Thomas Ullrich

Publications and Research

The production of a hard dijet with small transverse momentum imbalance in semi-inclusive DIS probes the conventional and linearly polarized Weizsäcker-Williams (WW) transverse momentum dependent (TMD) gluon distributions. The latter, in particular, gives rise to an azimuthal dependence of the dijet cross section. In this paper we analyze the feasibility of a measurement of these TMDs through dijet production in DIS on a nucleus at an electron-ion collider. We introduce the MCDIJET Monte Carlo generator to sample quark-antiquark dijet configurations based on leading-order parton level cross sections with WW gluon distributions that solve the nonlinear small-x QCD evolution equations. …

Hardly Habitual: Chimpanzees And Gorillas Show Flexibility In Their Motor Responses When Presented With A Causally-Clear Task, Sarah L. Jacobson, Lydia M. Hopper

Publications and Research

In contrast to reports of wild primates, studies of captive primates' flexibility often reveal conservatism: individuals are unable to switch to new and more efficient strategies when task demands change. We propose that such conservatism might be a result of task design and hypothesize that conservatism might be linked to primates' lack of causal understanding in relation to experimental apparatuses. We investigated if chimpanzees (Pan troglodytes) and western lowland gorillas (Gorilla gorilla gorilla) would show greater flexibility when presented with a causally-clear task. We presented six chimpanzees and seven gorillas with a clear tube from which …

Optimal Inventory Strategy Under Risk: A Contingent Claims Approach, Jesse Daniel Klebe

Agribusiness and Applied Economics

Inventory management in the agriculture industry involves many sources of risk in terms of demand uncertainty as well as uncertain margins. Divulging an optimal inventory strategy can prove cumbersome to logistics managers. In this thesis, inventory is viewed as a real option on the ability to operate. Contingent claims inventory (CCI) analysis, paired with stochastic binomial real option valuation, provides a model which values the real option embedded in holding inventory and iterates the purchasing strategy until expected profit is maximized. This framework is applied to three industry cases pertaining to: wheat flour milling, fertilizer merchandising, and bulk shipments via …

The Effects Of Futures Markets On The Spot Price Volatility Of Storable Commodities, Cole Louis Goetz

Agribusiness and Applied Economics

This thesis examines the relationship between spot prices, futures prices, and ending stocks for storable commodities. We used Granger causality and DAGs to determine causal relationships and cointegration tests to determine long-run relationships. We use VAR/VECM and consider innovation accounting techniques to see how volatility in one market affects the price behavior and volatility in the other market. Results suggest that for agricultural commodities, innovations in futures price permanently increase the level of spot prices while accounting for much of spot price variance over time. For national oil, shocks to futures price decrease the level of spot price in the …

Globally Detected Volcanic Lightning And Umbrella Dynamics During The 2014 Eruption Of Kelud, Indonesia, Kirstin A. Hargie, Alexa R. Van Eaton, L. G. Mastin, Robert H. Holzworth, John W. Ewert, Michael Pavolonis

Geology Faculty Publications and Presentations

Volcanic lightning shows considerable promise as a monitoring and research tool to characterize explosive eruptions. Its key strengths are rapid and remote detection, because the radio signals produced by lightning can propagate thousands of km at the speed of light. Despite these tantalizing properties, the scientific work on volcanic lightning has only recently started gaining momentum. Much more is needed to understand what lightning reveals about the evolution of an eruption in near-real time. Here we examine the timing and energy release of lightning generated by the eruption of Kelud volcano in Indonesia on 13 February 2014, as detected by …

The Impacts Of Cost-Reducing Technology In The Gold And Oil Industries, Mark Alan Simonson

Agribusiness and Applied Economics

This thesis explores the question of what drives the development of cost-reducing technology. It will also explore this question in the gold and oil industries. It will integrate Paul Romer’s idea that investment in technology is an endogenous factor in the econometric testing. This matters because while a time lag may exist between investment in a commodity and one’s return on such investment, the role of changes in price and elasticity aid in driving such investment.

Bankruptcy Model Application To Missouri River Water Allocation, Heshani Anjalie Manaweera Manaweera Wickramage

Agribusiness and Applied Economics

Growing demand for water and improper resource management over the years have led conflicts among states and countries. This research applies cooperative game theory. The bankruptcy model, where claims for resources exceed their total availability, was applied to Missouri River water allocation during dry years. In this study, five allocation rules were applied. These include Proportional, Constrained Equal Award, Sequential Sharing Rules based Proportional, Mianabadi’s methodology, and a proposed Modified Constrained Equal Award rule in allocating Missouri River water among two agents where their primary purposes were managing the reservoir water level and navigation channel. Selection of the best allocation …

Agribusiness and Applied Economics

This study examines the risk and returns to owning United States farmland. State, regional, and national farmland returns from 1998 to 2018 are analyzed via the capital asset pricing model. Results show that farmland may be an effective route of investment portfolio diversification due to its favorable returns and low correlation with other commonly held assets. This study’s findings are generally consistent with similar research conducted in the past.

Photoemission Electron Microscopy To Characterize Slow Light In A Photonic Crystal Line Defect, Theodore Stedmark, Rolf Könenkamp

Physics Faculty Publications and Presentations

Using femtosecond nonlinear photoemission electron microscopy (PEEM) we provide a detailed characterization of slow light in a small-size asymmetric photonic crystal structure. We show that PEEM is capable of providing a unique description of the light propagation in such structures by direct imaging of the guided mode. This noninvasive characterization technique allows modal properties such as effective index, phase velocities, and group velocities to be determined. Combining experimental results with finite element method simulation calculations, we study slow light phenomena in a photonic crystal defect mode, and we produce a comprehensive picture of the mechanisms behind it. Our results illustrate …

Agricultural Field Applications Of Digital Image Processing Using An Open Source Imagej Platform, Sunoj Shajahan

Agribusiness and Biosystems Engineering

Digital image processing is one of the potential technologies used in precision agriculture to gather information, such as seed emergence, plant health, and phenology from the digital images. Despite its potential, the rate of adoption is slow due to limited accessibility, unsuitability to specific issues, unaffordability, and high technical knowledge requirement from the clientele. Therefore, the development of open source image processing applications that are task-specific, easy-to-use, requiring fewer inputs, and rich with features will be beneficial to the users/farmers for adoption. The Fiji software, an open source free image processing ImageJ platform, was used in this application development study. …

How Much Do Emotional, Behavioral, And Cognitive Factors Actually Impact College Student Attitudes Towards English Language Learning? A Quantitative And Qualitative Study, Xin Zuo, Regina D. Weaver, Julia Macrae, Limin Wang

Intensive English Language Program Faculty Publications and Presentations

Researchers have proposed many multidimensional frameworks to identify significant and potential factors, e.g., educational background, positive feelings and career aspirations, that impact English learning attitude in second language acquisition. Yet, there is still very little research to graphically describe the interactions between these factors and how these factors directly or indirectly impact learning attitude. To this end, a questionnaire survey was conducted in Changchun University of Technology. Statistical measures and Bayesian network analysis were introduced to quantitatively and qualitatively analyze the collected data. Furthermore, the significant attitudinal differences between students majoring in the Liberal Arts or Sciences were investigated for …

Perceptions Of Modern Meat-Animal Production From Consumers Two To Three Generations Removed From The Farm, Demetris Deon Reed

Animal Sciences

A consumer is defined as a person who purchases goods and services for personal use or a person or thing that eats or uses something (Merriam-Webster, 2019). Consumers either want or need to eat meat, whether it is for self-gratification or nutritive purposes. The modern consumer definition of “meat” has changed from the original hunter stalking prey to now contemporary livestock production practices that confine and feed sophisticated diets in an effort to achieve outstanding muscle-food quality. Those who produce and supply consumers with food and fiber must achieve a higher level of education in keeping with technological advances. Further, …

A Comparison Of Neighborhood-Scale Interventions To Alleviate Urban Heat In Doha, Qatar, Salim Ferwati, Cynthia Skelhorn, Vivek Shandas, Yasuyo Makido

Urban Studies and Planning Faculty Publications and Presentations

Recent evidence suggests that many densely populated areas of the world will be uninhabitable in the coming century due to the depletion of resources, climate change, and increasing urbanization. This poses serious questions regarding the actions that require immediate attention, and opportunities to stave off massive losses of infrastructure, populations, and financial investments. The present study utilizes microclimate modeling to examine the role of landscape features as they affect ambient temperatures in one of the fastest growing regions of the world: Doha, Qatar. By modeling three study sites around Doha—one highly urbanized, one newly urbanizing, and one coastal low-density urbanized—the …

Rescaling Air Quality Management: An Assessment Of Local Air Quality Authorities In The United States, Kelsea A. Schumacher, Vivek Shandas

Urban Studies and Planning Faculty Publications and Presentations

Institutional design for local air quality management is an underdeveloped area for research and practice. Although the United States has more than a century of organizational experience managing air quality at the Federal level, the recent years have seen a surge of interest in addressing municipal-scale solutions. Without information about the institutional designs, governance structures, and implications of localizing air quality management, practitioners may face challenges reducing population exposure to air pollutants. We offer a US national perspective on managing local air quality by assessing and surveying 117 local air quality authorities identified by the National Association of Clean Air …

This qualitative study used grounded theory to explore how rehearsals impacted five elementary literacy courses in a university teacher education program. Data comprised of prolonged observations, video recordings of rehearsals, and surveys. The process of coding and re-coding resulted in findings that reflect rehearsing provided Teacher Candidates with confidence with lesson presentation, improved understanding of literacy content, and understand how to make in-the-moment instructional decisions.

The Relationship Between A University-Based Mentorship Program And First-Year Teachers’ Performance, Alicia C. Stapp, Laura F. Prior, Catherine Harmon

Northwest Journal of Teacher Education

Teacher attrition affects both the stability and quality of schools. Nearly 24% of teachers leave after one year, 33% leave after three years, and 40-50% leave within their first five years (Geiger & Pivovarova, 2018). Effective mentorship programs can effectively assist teachers in overcoming the challenges that lead to resignation. This study implemented a teacher mentorship program where the mentor was a teacher educator who had worked with the mentees in their undergraduate program. Utilizing a qualitative approach, the study examined first-year teachers’ performance through monthly field observations, interviews, and self-reflections. Themes emerged that are critical to a first-year teacher’s …

Monitoring Annoyance And Stress Effects Of Wind Turbines On Nearby Residents: A Comparison Of U.S. And European Samples, Gundula Hübner, Johannes Pohl, Ben Hoen, Jeremy Firestone, Joseph Rand, Brian Elliott, Ryan Haac

Regional Research Institute for Human Services

As wind turbines and the number of wind projects scale throughout the world, a growing number of individuals might be affected by these structures. For some people, wind turbine sounds and their effects on the landscape can be annoying and could even prompt stress reactions. This comparative study analyzed a combined sample of survey respondents from the U.S., Germany and Switzerland. It utilized a newly developed assessment scale (ASScale) to reliably characterize these stress-impacted individuals living within populations near turbines. Findings indicate low prevalence of annoyance, stress symptoms and coping strategies. Noise annoyance stress (NASScale) was negatively correlated with the …

Attitudes Of U.S. Wind Turbine Neighbors: Analysis Of A Nationwide Survey, Ben Hoen, Jeremy Firestone, Joseph Rand, Debi Elliot, Gundula Hübner, Johannes Pohl, Ryan Wiser, Multiple Additional Authors

Regional Research Institute for Human Services

Experts predict continuing deployment of wind turbines in the United States, which will create more interactions between turbines and surrounding communities. Policymakers can benefit from analyses of existing wind projects that enable them to better understand likely effects on residents around proposed projects. Our analysis of a randomly drawn, representative national survey of 1705 existing U.S. wind project neighbors provides previously unavailable detail about factors influencing the attitudes of these neighbors toward their local wind projects. Overall, we find positive-leaning attitudes, which improve over time as individuals self-select into communities near existing wind projects. Hearing wind turbines leads to less-positive …
