Electrical and Computer Engineering Publications

Software game is a kind of application that is used not only for entertainment, but also for serious purposes that can be applicable to different domains such as education, business, and health care. Multidisciplinary nature of the game development processes that combine sound, art, control systems, artificial intelligence (AI), and human factors, makes the software game development practice different from traditional software development. However, the underline software engineering techniques help game development to achieve maintainability, flexibility, lower effort and cost, and better design. The purpose of this study is to assesses the state of the art research on the game …

Neural Network Models For Software Development Effort Estimation: A Comparative Study, Ali Bou Nassif, Mohammad Azzeh, Luiz Fernando Capretz, Danny Ho

Electrical and Computer Engineering Publications

Software development effort estimation (SDEE) is one of the main tasks in software project management. It is crucial for a project manager to efficiently predict the effort or cost of a software project in a bidding process, since overestimation will lead to bidding loss and underestimation will cause the company to lose money. Several SDEE models exist; machine learning models, especially neural network models, are among the most prominent in the field. In this study, four different neural network models – Multilayer Perceptron, General Regression Neural Network, Radial Basis Function Neural Network, and Cascade Correlation Neural Network – are compared …

The purpose of this study was to gain a better understanding of the issues that surround Chilean women in-service elementary teachers’ mathematics anxieties through Conversations that Matter. These conversations revolved around the participants’ mathematics experiences as students and practicing teachers. These narrative writings provide a powerful voice for the degree to which mathematics anxiety shapes teachers’ attitudes in this subject area as well as their ability to be successful in mathematics. The focused analysis for this paper was directed to impact the elementary mathematics education community with a specific focus on women who have had anxiety in learning and teaching …

Early Career Elementary Teachers’ Practices & Perceptions Related To Language & Language Learners, Erin Elizabeth Turner, Amy Roth Mcduffie, Amanda Tori Sugimoto, Kathleen Jablon Stoehr, Angela Witters, Julia Aguirre, Tonya Bartell, Corey Drake, Mary Q. Foote

Teacher Education

There has been limited attention to early career teachers’ (ECTs) understandings and practices related to language in teaching and learning mathematics. In this qualitative case study, we drew upon frameworks for teacher noticing to study the language practices of six early career elementary and middle school mathematics teachers. We describe multiple themes that cut across teachers’ noticing related to language and language learners, and discuss one theme (i.e., Perspectives on multiple languages) in more detail, including evidence of specific forms of noticing. Implications for teacher education and professional development are discussed.

Research Performance Support: Connecting Online Graduate Students From The Lms To The Library, Kim G. Read, Maureen J. Barney

When embedded in the learning management system throughout a course or program, performance support provides point of need research help and scaffolds students’ information literacy development. Librarians are able to focus their limited time helping students with their more advanced research needs.

Synchrony In A Boolean Network Of The L-Arabinose Operon In Escherichia Coli, Andy Jenkins, Matthew Macauley

Publications

The lactose operon in Escherichia coli was the first known gene regulatory network, and it is frequently used as a prototype for new modeling paradigms. Historically, many of these modeling frameworks use differential equations. More recently, Stigler and Veliz-Cuba proposed a Boolean network model that captures the bistability of the system and all of the biological steady states. In this paper, we model the well-known arabinose operon in E. coli with a Boolean network. This has several complex features not found in the lac operon, such as a protein that is both an activator and repressor, a DNA looping mechanism …

Learning Disabled Special Education Students And General Education Opportunities, Candace Pelt

Doctor of Education (EdD)

This study examined the relationship between the amount of time a student receives in general education and achievement scores for reading and math. Students selected were previously identified with a learning disability in the Newberg School District, and they were enrolled in classes during the 2014-2015 school year. Using a Multivariate Analysis of Variance (MANOVA), this study observed the correlation between students’ federal placement code and student achievement scores for both reading and math. For students with disabilities who also have an Individual Education Plan (IEP), the federal placement code identifies the amount of time a student spends in general …

Identifying Groundwater - Dependent Wetlands Of The Broome Sandstone Aquifer In The La Grange Groundwater Area, Nicholas Wright, Richard J. George Dr, Robert Paul, Paul Raper

Resource management technical reports

This report identifies wetlands that are likely to be dependent on the Broome Sandstone aquifer within the La Grange groundwater allocation area. The Broome Sandstone aquifer is the dominant groundwater resource in the area. With potential agricultural growth of this area, it is necessary to understand, monitor and manage the aquifer and its dependent wetlands. This report describes how we created a watertable surface that was used to identify wetlands and to determine which of the previously mapped wetlands are likely to be sourced from the Broome Sandstone aquifer. A watertable surface was created from 148 points taken from bore …

Gaussian And Cauchy Functions In The Filled Function Method -- Why And What Next: On The Example Of Optimizing Road Tolls, José Guadalupe Flores Muñiz, Vyacheslav V. Kalashnikov, Nataliya Kalashnykova, Vladik Kreinovich

Departmental Technical Reports (CS)

In many practical problems, we need to find the values of the parameters that optimize the desired objective function. For example, for the toll roads, it is important to set the toll values that lead to the fastest return on investment.

There exist many optimization algorithms, the problem is that these algorithms often end up in a local optimum. One of the promising methods to avoid the local optima is the filled function method, in which we, in effect, first optimize a smoothed version of the objective function, and then use the resulting optimum to look for the optimum of …

A Simplified Derivation Of Confidence Regions Based On Inferential Models, Vladik Kreinovich

Departmental Technical Reports (CS)

Recently, a new inferential models approach has been proposed for statistics. Specifically, this approach provides a new random-set-based way to come up with confidence regions. In this paper, we show that the confidence regions obtained by using the main version of this new methodology can also be naturally obtained directly, without invoking random sets.

Dust Devil Populations And Statistics, Ralph D. Lorenz, Brian K. Jackson

Physics Faculty Publications and Presentations

The highly-skewed diameter and pressure drop distributions of dust devils on Earth and Mars are noted, and challenges of presenting and comparing different types of observations are discussed. The widely- held view that Martian dust devils are larger than Earth's is critically-assessed: the question is confounded somewhat by different observation techniques, but some indication of a ~3x larger population on Mars is determined. The largest and most intense (in a relative pressure sense) devils recorded are on Mars, although the largest reported number density is on Earth. The difficulties of concepts used in the literature of 'average' diameter, pressure cross …

Getting Short‐Changed? The Impact Of Outside Money On District Representation, Anne E. Baker

Political Science

Objective
As incumbent House members increasingly recruit campaign contributions from individuals who reside outside of their districts, this raises the question of whether a dependency on outside money affects members’ responsiveness and ideological proximity to district constituents.

Method
Using data from the Cooperative Congressional Election Studies of 2006, 2008, and 2010 as well as individual contribution data corresponding to those years from the U.S. Federal Election Commission, I examine this relationship using responsiveness and proximity models of representation.

Results
I find a dependency on outside contributions decreases members’ responsiveness to their districts and increases the members’ ideological extremity. Moreover, within‐district …

Neutron Correlations In The Decay Of The First Excited State Of 11li, Jenna K. Smith, Thomas J. Baumann, Daniel Bazin, James Brown, Paul A. Deyoung, Nathan H. Frank, Michael D. Jones, Zack Kohley, Bryan A. Luther, B. S. Marks, Artemis Spyrou, Sharon L. Stephenson, Michael R. Thoennessen, Alexander S. Volya

Physics and Astronomy Faculty Publications

The decay of unbound excited ¹¹Li was measured after being populated by a two-proton removal from a ¹³B beam at 71 MeV/nucleon. Decay energy spectra and Jacobi plots were obtained from measurements of the momentum vectors of the ⁹Li fragment and neutrons. A resonance at an excitation energy of ∼1.2 MeV was observed. The kinematics of the decay are equally well fit by a simple dineutron-like model or a phase-space model that includes final state interactions. A sequential decay model can be excluded.

We present the discovery of a hot Jupiter transiting the V = 9.23 mag main-sequence A-star KELT-17 (BD+14 1881). KELT-17b is a ${1.31}_{-0.29}^{+0.28}\,{M}_{{\rm{J}}}$, ${1.525}_{-0.060}^{+0.065}\,{R}_{{\rm{J}}}$ hot-Jupiter in a 3.08-day period orbit misaligned at −115fdg9 ± 4fdg1 to the rotation axis of the star. The planet is confirmed via both the detection of the radial velocity orbit, and the Doppler tomographic detection of the shadow of the planet during two transits. The nature of the spin–orbit misaligned transit geometry allows us to place a constraint on the level of differential rotation in the host star; we find that KELT-17 is consistent with …

Concluding Commentary: Children In All Cancer Prevention Policy Decisions., Cynthia F Bearer, Lynn Goldman

Environmental and Occupational Health Faculty Publications

This interesting series of articles on Opportunities for Cancer Prevention During Early Life brings many ideas for the primary prevention of cancer in childhood, or in adults due to early life events. The economic burden not only of cancer mortality but also of lifelong morbidity among cancer survivors, as shown by Guy et al,1 raises the importance of this critical public health issue. The topics of these articles were developed during online seminars with the pioneers in this area, some of whom authored the articles. They reflect the determinants of health diagrammed so eloquently in Healthy People 2020.2 …

The Results Of Deliberation, Maggie Wittlin

The University of New Hampshire Law Review

When evaluating whether to sue, prosecute, settle, or plead, trial lawyers must predict the future—they need to estimate how likely they are to win a given case in a given jurisdiction. Social scientists have used mock juror studies to produce a vast body of literature showing how different variables influence juror decision making. But few of these studies account for jury deliberation, so they present an impoverished picture of how these effects play out in trials and are of limited usefulness.

This Article helps lawyers better predict the future by presenting a novel computer model that extrapolates findings about jurors …

A Mixed Method Study On Schema-Based Instruction, Mathematical Problem Solving Skills, And Students With An Educational Disability, Bill Casner

Dissertations

The purpose of this study was to determine the student outcomes of implementing schema-based instruction on students in grades 3-8 identified with an educational disability and ascertain how students’ developed mathematical problem solving skills. After special education teachers in a metropolitan school district in the Midwest administered a pre-assessment, the researcher used the results to select 21 students with an educational disability to participate in the mixed-methods study. Special education teachers implemented Asha K. Jitendra’s (2007) educational program titled, Solving Math Word Problems: Teaching Students with Learning Disabilities Using Schema-Based Instruction, during the 2013-2014 school year and taught participants using …

Fine Arts Coursework And Student Achievement Among African-American Students In A Midwest Setting, Douglas Erwin

Dissertations

The researcher designed this study to investigate a possible correlation between the number of years of fine arts coursework and achievement on the American College Test (ACT). The district studied was predominantly African American; therefore, similar schools may use the results to plan strategies to reduce the achievement gap. Results included a mild positive correlation between student ACT achievement and coursework in visual arts, and a moderate correlation between ACT achievement and performing arts. The more fine arts coursework a student received, the higher his or her ACT score. The researcher conducted a z-test for difference in means to compare …

Comparison Of Classroom Grades And Missouri End-Of-Course Exam Scores, Rodney Delmont

Dissertations

Educational leaders are tasked with finding the best practices for motivating students and accurately reporting progress (Popham, 2011). Additionally, the alignment of curriculum, assessment, and pedagogy can facilitate changes in education (Klenowski & Wyatt-Smith, 2014). Therefore, as districts align curriculum to assessment standards, students’ scores on assessments should increase (Squires, 2012). The purpose of this study was to determine if a correlation exists between Missouri English II end-of-course (EOC) exam scores and student grade-point averages (GPAs) earned in English II. Moreover, data were examined to determine if a correlation exists among student gender, Missouri English II EOC scores, and student …

Towards A Reverse Newman’S Theorem In Interactive Information Complexity, Joshua Brody, H. Buhrman, M. Koucký, B. Loff, F. Speelman, N. Vereshchagin

Computer Science Faculty Works

Newman’s theorem states that we can take any public-coin communication protocol and convert it into one that uses only private randomness with but a little increase in communication complexity. We consider a reversed scenario in the context of information complexity: can we take a protocol that uses private randomness and convert it into one that only uses public randomness while preserving the information revealed to each player? We prove that the answer is yes, at least for protocols that use a bounded number of rounds. As an application, we prove new direct-sum theorems through the compression of interactive communication in …

The Effects Of Professional Development On Elementary Students’ Mathematics Achievement, Jonathan L. Brendefur, Keith W. Thiede, Sam Strother, Dan Jesse, John Sutton

Curriculum, Instruction, and Foundational Studies Faculty Publications and Presentations

This paper describes the effects of a professional development (PD) program – Developing Mathematical Thinking – on student achievement. Six Title I elementary schools with similar demographics, within one school district, were chosen to participate as either a treatment or comparison school. Three schools were chosen to participate in professional development that incorporates effective PD recommendations. All the teachers had to participate in all aspects of the PD, thereby eliminating potential self-selection bias. Using the state standardized achievement test as the before and after measure, results suggest improved student performance after professional development was implemented over a two year period.

Towards Using Certificate-Based Authentication As A Defense Against Evil Twins In 802.11 Networks, Travis S. Hendershot

Theses and Dissertations

Wireless clients are vulnerable to exploitation by evil twins due to flaws in the authentication process of 802.11 Wi-Fi networks. Current certificate-based wireless authentication protocols present a potential solution, but are limited in their ability to provide a secure and usable platform for certificate validation. Our work seeks to mitigate these limitations by exploring a client-side strategy for utilizing alternative trust models in wireless network authentication. We compile a taxonomy of various trust models for conducting certificate-based authentication of wireless networks and methodically evaluate each model according to desirable properties of security, usability, and deployability. We then build a platform …

Geochemical Comparison Of Ancient And Modern Eolian Dune Foresets Using Principal Components Analysis, David A. Little

Theses and Dissertations

Geochemistry has been used to determine the provenance and diagenetic history of eolian sandstone deposits. However, the grain size, sorting, cementation, and detrital composition of eolian units can change along dune foreset laminae. The purpose of this study was to test for consistent trends of compositional change along dune foresets. Such trends could increase the quality of geochemical sampling of eolian sandstones and possibly aid in estimating the original height of ancient sand dunes. XRF data was gathered for both major and trace elements from the Pennsylvanian to Permian Weber Sandstone, Early Jurassic Navajo Sandstone, and modern Coral Pink Sand …
