Measuring Language Development Through Self-Assessment, Troy L. Cox, Dan Dewey

Faculty Publications

Talk to any cyclist or runner, and they can name instances when the universe seems to conspire against them with headwinds that hinder their progress. It is easy to identify and often blame external forces for causing us to fail. Conversely, we often attribute success to our own ability, being blissfully unaware of the tailwinds that assist us. This blindness to headwind/tailwind asymmetry (Davidai & Gilovich, 2016) in viewing one’s own performance is not limited solely to endurance athletes but can be found in other areas of self-assessment. Performance rarely occurs in a vacuum. There are typically external forces that …

The Absence Of A Religiolect Among Latter-Day Saints In Southwest Washington, Joseph A. Stanley

Faculty Publications

The term religiolect was coined by Benjamin Hary (1992, xiii) to describe a variety of language used by a distinct religious community, originally within the context of the Jewish linguistic spectrum. Religion has been shown to play an important role in various aspects of language, such as Arabic loanword adoption among Telugu speakers (Salami 2010), Persian loanwords and greetings among English-speaking Bahá’is (Masumian 2015), fluency in Sanskrit (Christian 1976), language choice among Hindus in the United States (Pandharipande 2010), maintenance of Hakka in East Malaysia (Ding and Goh 2020), and prevalence of linguistic fossils in Jewish Malayalam (Gamliel 2017). “Christianese,” …

Back Vowel Distinctions And Dynamics In Southern Us English, Joseph A. Stanley, Margaret E. L. Renwick

Faculty Publications

We investigate low/back vowels /u, oʊ, ʊ, ɔ, ɑ/ in Southern American English (SAE).

Research on SAE has analyzed changes in position over generational time.

Most work on trajectories is limited to impressionistic coding (“loss of upgliding”) or reduces trajectories to summary statistics (vector length, rate of change).

We analyze both the position and the shape of back vowels’ formant trajectories in apparent time, using new data from the Digital Archive of Southern Speech (DASS).

The View Of Southern Vowels From Large-Scale Data, William A. Kretzschmar Jr., Margaret E. L. Renwick, Katherine I. Kuiper, Lisa M. Lipani, Michael L. Olsen, Rachel M. Olsen, Joseph A. Stanley

Faculty Publications

Abstract:

We have extracted c. 2 million tokens of vowels from a rigorous sample of 63 speakers across the American South in an NSF-funded project for forced alignment and automatic formant extraction. We show how our vowel measurements across the whole region differ from national mean F1/F2 scores. We contrast men and women, and African Americans and non- African Americans, within the Southern region.

Locations, Programs, And Content Of Graduate Education In Business Communication, Stephen A. Carradini, Matt Baker, Matthew R. Sharp, Elise Davidson

Faculty Publications

This study explored locations, programs, and content of graduate education in business communication to provide guidance for prospective graduate students interested in becoming business communication faculty.

The researchers conducted a survey of business communication scholars, drawing on the backgrounds and knowledge of those who currently teach and research business communication.

Findings indicate that 93 universities offer programs supporting graduate business communication education. This number dwarfs the 12 previously documented programs. These 93 programs are rarely called “business communication.” More respondents received training in business communication practice in master’s programs than in doctoral programs, while more respondents received training in pedagogy …

Exploring Wellbore And Reservoir Temperature Profiles In Fluid Circulation And Production Operations, Ahmed Qasim Al Saedi

Doctoral Dissertations

"The wellbore heat flow occurs during different well operations resulting from any temperature differences between the wellbore fluid and the adjacent formation. Understanding the direction and mechanism of heat flow whether it is conduction or convection help to represent this heat exchange mathematically. However, the only available factor used to understand the heat flow behavior is the measured wellbore temperature which can be obtained from the direct measurement while drilling or circulation operations, well logging, well test, or from the production operations. Also, the initial geothermal formation temperature resulting from the geothermal gradient will help to understand the undistributed formation …

Rubric Rating With Mfrm Versus Randomly Distributed Comparative Judgment: A Comparison Of Two Approaches To Second-Language Writing Assessment, Maureen E. Sims, Troy L. Cox, Grant T. Eckstein, K. James Hartshorn, Matthew P. Wilcox, Judson M. Hart

Faculty Publications

The purpose of this study is to explore the reliability of a potentially more practical approach to direct writing assessment in the context of ESL writing. Traditional rubric rating (RR) is a common yet resource-intensive evaluation practice when performed reliably. This study compared the traditional rubric model of ESL writing assessment and many-facet Rasch modeling (MFRM) to comparative judgment (CJ), the new approach, which shows promising results in terms of reliability. We employed two groups of raters—novice and experienced—and used essays that had been previously double-rated, analyzed with MFRM, and selected with fit statistics. We compared the results of the …

The Picrat Model For Technology Integration In Teacher Preparation, Royce Kimmons, Charles R. Graham, Richard E. West

Faculty Publications

Technology integration models are theoretical constructs that guide researchers, educators, and other stakeholders in conceptualizing the messy, complex, and unstructured phenomenon of technology integration. Building on critiques and theoretical work in this area, the authors report on their analysis of the needs, benefits, and limitations of technology integration models in teacher preparation and propose a new model: PICRAT. PIC (passive, interactive, creative) refers to the student’s relationship to a technology in a particular educational scenario. RAT (replacement, amplification, transformation) describes the impact of the technology on a teacher’s previous practice. PICRAT can be a useful model for teaching technology integration, …

Supporting Students During Covid-19: Developing And Leveraging Academic Communities Of Engagement In A Time Of Crisis, Jered Borup, Michelle Jensen, Leanna Archambault, Cecil R. Short, Charles R. Graham

Faculty Publications

As school closures require educators to transition to remote teaching, relevant models for supporting students are necessary. This article discusses Academic Communities of Engagement (ACE), a framework identifying two communities to help support student engagement: (a) the course community associated with course or school (teacher, peers, administrators, counselors) and (b) students’ personal community with long-standing relationships (parents, siblings, friends). Within the framework these communities can provide affective, behavioral, and cognitive support in online (remote) settings. Examples from two schools that had to go remote demonstrate application of the framework promoting student engagement and success.

Academic Communities Of Engagement: An Expansive Lens For Examining Support Structures In Blended And Online Learning, Jered Borup, Charles R. Graham, Richard E. West, Leanna Archambault, Kristian J. Spring

Faculty Publications

In this article we share the Academic Communities of Engagement (ACE) framework, which describes a student’s ability to engage affectively, behaviorally, and cognitively in an online or blended course independently and with support. Based on Vygotsky’s (Mind in society: the development of higher psychological processes, Harvard University Press, Cambridge, 1978) zone of proximal development, the framework examines how a student’s ability to engage in online or blended courses increases with support from two types of communities. The course community is organized and facilitated by those associated with the course or program. The personal community is comprised of actors not officially …

Audit Committee Accounting Expertise And The Mitigation Of Strategic Auditor Behavior, James C. Hansen, Ling Lei Lisic, Timothy Seidel, Michael S. Wilkins

Faculty Publications

Our study is motivated by the theory of credence goods in the auditing setting. We propose that audit committee accounting expertise should reduce information asymmetries between the auditor and the client, thereby limiting auditors’ ability to over-audit and under-audit. Consistent with this notion, our results indicate that when audit committees have accounting expertise, clients (1) pay lower fees when changes in standards decrease required audit effort; (2) pay a smaller fee premium in the presence of remediated material weaknesses; and (3) have a reduced likelihood of restatement when audit market competition is high. Our findings in the under-auditing setting generally …

A Novel Calculation Method To Design Parasitic Decoupling Technique For Two Antennas, Min Li, Di Wu, Bing Xiao, Kwan Lawrence Yeung, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a systematic and calculation-based parasitic decoupling technique (PDT) is proposed to mitigate the mutual coupling between two closely coupled antennas. The adopted parasitic decoupling structure consists of two transmission lines connected to the feed lines of antennas and a parasitic element connected with a transmission line and terminated by a reactive load. Rigorous decoupling theory and systematic design procedures are presented. The lengths of transmission lines and value of reactive load can be precisely calculated to increase antenna isolation. The superiority of the proposed PDT is verified by four decoupling examples. The simulated and measured results show …

Numerical Methods For Electromagnetic Modeling Of Graphene: A Review, Kaikun Niu, Ping Li, Zhixiang Huang, Li (Lijun) Jun Jiang, Hakan Bagci

Electrical and Computer Engineering Faculty Research & Creative Works

Graphene's remarkable electrical, mechanical, thermal, and chemical properties have made this the frontier of many other 2-D materials a focus of significant research interest in the last decade. Many theoretical studies of the physical mechanisms behind these properties have been followed by those investing the graphene's practical use in various fields of engineering. Electromagnetics, optics, and photonics are among these fields, where potential benefits of graphene in improving the device/system performance have been studied. These studies are often carried out using simulation tools. To this end, many numerical methods have been developed to characterize electromagnetic field/wave interactions on graphene sheets …

Enhanced Pml Based On The Long Short Term Memory Network For The Fdtd Method, He Ming Yao, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

This paper proposes a new absorbing boundary condition (ABC) computation approach based on the deep learning technique. Benefited from the sequence dependence feature, the Long Short-Term Memory (LSTM) network is employed to replace the conventional perfectly matched layer (PML) ABC for the Finite-Difference Time-Domain (FDTD) solving process. The newly proposed LSTM based PML model is trained by the electromagnetic field data on the interface of the conventional PML. Different from the conventional PML, the newly proposed model only needs one cell layer as the boundary. Hence, the newly proposed method conveniently reduces both the algorithm's complexity and the area of …

Pseudospin-Polarized Topological Line Defects In Dielectric Photonic Crystals, Menglin L.N. Chen, Li (Lijun) Jun Jiang, Zhihao Lan, Wei E.I. Sha

Electrical and Computer Engineering Faculty Research & Creative Works

Electromagnetic (EM) topological insulators have been extensively explored due to the robust edge states they support. In this work, we propose a topological EM system based on a line defect in topologically nontrivial photonic crystals (PCs). With a finite-difference supercell approach, modal analysis of the PC structure is investigated in detail. The topological line-defect states are pseudospin polarized and their energy flow directions are determined by the corresponding pseudospin helicities. These states can be excited by using two spatially symmetric line-source arrays carrying orbital angular momenta. The feature of the unidirectional propagation is demonstrated, and it is stable when disorders …

A Novel Data-Driven Scheme For The Ship Wake Identification On The 2-D Dynamic Sea Surface, Yanming Zhang, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Because the ship wake spreads into an area much larger than that of the ship hull in the sea surface, it has been widely used in the ship detection. However, due to the complex sea wave motion and the high sea state, the ship wake detection is still a challenging task. In this paper, we propose a novel data-driven method based on dynamic mode decomposition (DMD) to detect, reconstruct, and locate the Kelvin wake on the two-dimensional dynamic sea surface. Through the proposed method, the sea's dynamic characteristics including the oscillation frequency and decay/growth rate of ship wakes and the …
