Group-Based Training On Trial-Based Functional Analysis, Christina Noel, Thomas Gross, Grant Hacherl, Meaghan Ritchie, Matthew Howerton
Kentucky Teacher Education Journal: The Journal of the Teacher Education Division of the Kentucky Council for Exceptional Children
A functional behavior assessment (FBA) of challenging behavior has been identified as a High-Leverage Practice in the social/emotional/behavior area (HLPs; McLeskey et al., 2017). Despite the importance of FBAs to classroom practices, many FBAs are conducted outside of classroom settings. Evidence suggests that FBAs may be more effective when conducted in a child’s typical classroom setting. A trial-based functional assessment (TBFA) is a variant of an FBA that is conducted by practitioners in a child’s classroom environment. The purpose of this paper is to outline the important components that should be included in a TBFA group training designed for practitioners …
Tracking The Year-To-Year Variation In The Spectral Energy Distribution Of The Narrow-Line Seyfert 1 Galaxy Mrk 335, Dirk Grupe
Faculty Research at Morehead State University
Multi-wavelength monitoring of Mrk 335 with Swift between 2007-2019 are used to construct annual spectral energy distributions and track year-to-year changes. Non-contemporaneous archival data prior to 2007 are used to build a bright state SED. In this work, the changes are examined and quantified to build the foundation for future SED modelling. The yearly SEDs trace a downward trend on the average, with the X-ray portion varying significantly and acquiring further lower values in the past two years when compared to the optical/UV portion of SED. The bolometric Eddington ratios derived using optical/UV to X-ray SEDs and the calculated X-ray …

Factors Associated With Students Graduating With Stem Degrees At A Military Academy: Improving Success By Identifying Early Obstacles, Wilson J. Gonzalez-Espada
Faculty Research at Morehead State University
The United States is not graduating enough science, technology, engineering, and mathematics (STEM) majors for the increasing number of available employment opportunities and national security needs. The purpose of this study was to quantify the magnitude of STEM attrition at the United States Air Force Academy (USAFA), a military service academy and one of the three commissioning sources of officers for the United States Air Force. Also, the study identified factors associated with STEM attrition among students. Despite strong academic preparation, of the students who reported their intention to major in a STEM discipline as incoming freshmen, 36.4% switched and …
Betting On Better Buoyancy? Be Careful What You Wish For, Wilson J. Gonzalez-Espada, Brooke S. Jones
Betting On Better Buoyancy? Be Careful What You Wish For, Wilson J. Gonzalez-Espada, Brooke S. Jones
Faculty Research at Morehead State University
The study of buoyancy is common in physics classrooms. In the last 20 years, several educators have described, theoretically and experimentally, buoyant forces and Archimedes’ principle, both in The Physics Teacher1- 8 and elsewhere.9-16 However, as far as I know, no one has reported on the pedagogical implications and experimental results of measuring the buoyant force acting on a submerged object using the overflow can method and a surface tension lowering agent (soapy water), as described in an online You- Tube video aimed at teachers and produced by PASCO.17 This article critically examines the claims presented in this video using …

The Perverse Dynamics Of University Career: A Narrative Analysis Based On The Personal And Professional Implications, Gustavo González-Calvo, Alejandra Hernando-Garijo, David Hortigüela Alcalá, Ángel Pérez-Pueyo
The Qualitative Report
We seek to describe some of the features and symptoms that define novice university teachers in their attempts to pursue a professional career at university. Presently, university culture revolves around the evaluation of professionals based on the quantity of work published in high-impact journals (“weight evaluations”).This situation not only has its effects at a personal level, but also on the quality of the education that teachers might wish to impart. Nine university teachers -five women and four men- with experience of between three and five years in different knowledge areas were interviewed to ascertain these symptoms. The results reflected the …

The April–June 2020 Super-Outburst Of Oj 287 And Its Long-Term Multi-Wavelength Lightcurve With Swift: Binary Supermassive Black Hole And Jet Activity, Dirk Grupe
Faculty Research at Morehead State University
We report detection of a very bright X-ray-UV-optical outburst of OJ 287 in April–June 2020; the second brightest since the beginning of our Swift multi-year monitoring in late 2015. It is shown that the outburst is predominantly powered by jet emission. Optical-UV-X-rays are closely correlated, and the low-energy part of the XMM-Newton spectrum displays an exceptionally soft emission component consistent with a synchrotron origin. A much harder X-ray powerlaw component (x = 2:4, still relatively steep when compared to expectations from inverse-Compton models) is detected out to 70 keV by NuSTAR. We find evidence for reprocessing around the Fe region, …

Faculty Research at Morehead State University
Parents of a football player filed a lawsuit against Valley Christian School for common law negligence, medical negligence, and violations of the Zackery Lystedt law, which is a law that was implemented in Washington to protect athletes who have sustained a concussion from further injuring themselves. The lawsuit was filed because their son, Drew Swank, died two days after a football game in which he had been medically cleared to play in after receiving a head injury the week prior. The Swanks filed the lawsuit claiming that the football coach and doctor were negligent in allowing Drew to play, knowing …

Astrodance: Engaging Deaf And Hard-Of-Hearing Students In Astrophysics Via Multimedia Performances, Jason Nordhaus, Manuela Campanelli, Joe Bochner, Thomas Warfield, Hans-Peter Bischof, Jake Noel-Storr
Journal of Science Education for Students with Disabilities
The dynamics of gravitating astrophysical systems such as black holes and neutron stars are fascinatingly complex, offer some of nature's most spectacular phenomena, and capture the public's imagination in ways that few subjects can. Here, we describe AstroDance, a multi-media project to engage deaf and hard-of-hearing (DHH) students in astronomy and gravitational physics. AstroDance incorporates multiple means of representation of scientific concepts and was performed primarily for secondary and post-secondary audiences at ~20 venues in the northeastern US prior to the historic first detection of gravitational waves. As part of the AstroDance project, we surveyed ~1000 audience members roughly split …

Discovery Of Recombining Plasma Associated With The Candidate Supernova Remnant G189.6+3.3 With Suzaku, Thomas G. Pannuti
Discovery Of Recombining Plasma Associated With The Candidate Supernova Remnant G189.6+3.3 With Suzaku, Thomas G. Pannuti
Faculty Research at Morehead State University
We present the results of an X-ray spectral analysis of the northeast region of the candidate supernova remnant G189.6+3.3 with Suzaku. K-shell lines from highly ionized Ne, Mg, Si, and S were detected in the spectrum for the first time. In addition, a radiative recombining continuum (RRC) from He-like Si was clearly seen near 2.5 keV. This detection of an RRC reveals for the first time that G189.6+3.3 possesses an X-ray-emitting recombining plasma (RP). The extracted X-ray spectrum in the 0.6–10.0 keV energy band is well fitted with a model consisting of a collisional ionization equilibrium plasma component (associated with …

Self-Determination Theory And Faculty Behavior: A Quantitative Study Of Faculty Leaders' Use Of Assessment Evidence, Joseph D. Levy
Self-Determination Theory And Faculty Behavior: A Quantitative Study Of Faculty Leaders' Use Of Assessment Evidence, Joseph D. Levy
Dissertations
Despite assessment of student learning being essential work in higher education, a number of institutions have noted faculty could more effectively be using assessment results (Jankowski et al., 2018; Kuh et al., 2015; Metzler & Kurz, 2019; Suskie, 2014). This study applied Self-Determination Theory (SDT) as a theoretical framework to provide context for faculty behavior associated with assessment actions (Fuller et al., 2016; Ryan & Deci, 2000). Mostly quantitative data were collected via electronic survey of faculty program leaders at a single institution, National Louis University (NLU). Results indicated a significant and positive relationship suggesting an increase in meeting the …

From Classroom To Real-World: Preparing Students For The Newsroom, Katherine Allred
Electronic Theses & Dissertations
The purpose of this study was to determine the preparedness of college graduates entering the news field. Employers search for the best possible person with the necessary skills and qualifications required to complete the day-to-day functions of a job. In television news, very specific traits and skills are needed to work in the newsroom environment. Working as a news producer at a small TV station for almost seven years, new employees, specifically reporters, would struggle with some of the basic skills needed for their job. Are universities teaching students everything they need to know? How are they succeeding? If they …

Exploring Stem Kit Diagrams For Braille Readers In Inclusive Classrooms, Sariat A. Adelakun Dr
Journal of Science Education for Students with Disabilities
Diagrams appears in many school subjects but more prominent in science and mathematics taught in schools. Accessing these diagrams in an inclusive classroom has been identified to be problematic for blind students partly due to the teaching resources available and personnel type, support and sufficiency. Diagrams are mostly omitted by teachers leaving the blind person out in such classroom to access portion of education received by their peers. In many instances, questions with diagrams are treated as bonus for blind students in some countries which is not fair to them. This study explored the efficacy of STEM Kit diagrams on …

Reign Of Terror In West Kentucky? (Part 2), Dieter C. Ullrich, Berry Craig
Faculty Research at Morehead State University
During fifty-one days in the summer of 1864 a “reign of terror” existed in Western Kentucky under the military command of General Eleazar Arthur Paine, at least that is what historians and folklorists have written over the past 150 years. However, new evidence from contemporary documents provide a contradictory narrative to the story.
Processing Gapping: Parallelism And Grammatical Constraints, Katy Carlson
Processing Gapping: Parallelism And Grammatical Constraints, Katy Carlson
Faculty Research at Morehead State University
This study aims to test two hypotheses about the online processing of Gapping: whether the parser inserts an ellipsis site in an incremental fashion in certain coordinated structures (the Incremental Ellipsis Hypothesis), or whether ellipsis is a late and dispreferred option (the Ellipsis as a Last Resort Hypothesis). We employ two offline acceptability rating experiments and a sentence fragment completion experiment to investigate to what extent the distribution of Gapping is controlled by grammatical and extra-grammatical constraints. Furthermore, an eye-tracking while reading experiment demonstrated that the parser inserts an ellipsis site incrementally but only when grammatical and extra-grammatical constraints allow …

Second, current developments in the evolution of MathML are reviewed, noting their consequences for accessibility, and commenting on prospects for future improvement in the concrete experiences of users of assistive technologies. Recommendations are advanced for further research and development activities, emphasizing the cognitive aspects of user interface design.
All I Want To Say Is That They Don’T Really Care About Us: Creating And Maintaining Healing-Centered Collective Care In Hostile Times, Asif Wilson, Wytress Richardson
All I Want To Say Is That They Don’T Really Care About Us: Creating And Maintaining Healing-Centered Collective Care In Hostile Times, Asif Wilson, Wytress Richardson
Occasional Paper Series
Too often educators (care-givers) are left to navigate toxic work environments without proper support to combat the systemic issues they face daily. Institutions of higher education have neglected to make the health and well-being of care-givers a priority. This failure continues to maintain and perpetuate the oppressive conditions that mirror trauma, pain and stress. The authors of this study extend Ginwright’s (2018) healing centered engagement to conceptualize what they call healing centered collective care—a fugitive framework of care for the care-givers. Data was collected through two case studies and those generative themes are presented using testimonios from the authors.

Faculty Research at Morehead State University
Aims. We detected a very strong X-ray decline in the galaxy IRAS 23226-3843 within the XMM-Newton slew survey in 2017. Subsequently, we carried out multi-band follow-up studies to investigate this fading galaxy in more detail. Methods. We took deep follow-up Swift, XMM-Newton, and NuSTAR observations in combination with optical SALT spectra of IRAS 23226-3843 in 2017. In addition, we reinspected optical, UV, and X-ray data that were taken in the past. Results. IRAS 23226-3843 decreased in X-rays by a factor of more than 30 with respect to ROSAT and Swift data taken 10 to 27 years before. The broadband XMM-Newton/NuSTAR …
Undergraduate Educational Research Experiences In The Study Of Interior Design, Julia Virginia Pimentel Jiménez
Undergraduate Educational Research Experiences In The Study Of Interior Design, Julia Virginia Pimentel Jiménez
Dissertations
Designers create social constructions (experiences and interactions) for human beings among themselves and with and within interior environments to enhance meaning in people´s lives (Poldma, 2011). Those social constructions are created through the design process developed by the interior designer; that process relies heavily on design research. Therefore, it is at the undergraduate level that the passion for research should start for interior design (ID) students. Faculty in ID programs need to encourage that passion by engage students in meaningful learning experiences such as how to ask questions about users, functions, activities, and aesthetics.
This study explored what types of …
Breaking Down Barriers: An Investigation Into The Lack Of Female Head Coaches In Ncaa Affiliated Institutions, Steve Chen
Faculty Research at Morehead State University
The purpose of this study was to investigate the rationales behind the gender disparity between male and female head coaches at the National Collegiate Athletic Association (NCAA) affiliated institutions. Intercollegiate female athletic participation is at an all-time high. Yet, more women find male coaches coaching their sports. This study aimed to determine what hinders women from pursuing and obtaining head coaching positions at the collegiate level in either gender sports. Interviews were conducted in two different phases with two groups of NCAA Division-I female coaches (n = 22 and 8, respectively) in the southeast United States. The findings addressed the …
X-Ray Emission From The Mixed-Morphology Supernova Remnant Hb 9, Thomas G. Pannuti
X-Ray Emission From The Mixed-Morphology Supernova Remnant Hb 9, Thomas G. Pannuti
Faculty Research at Morehead State University
We present the results of a spectral analysis of the central region of the mixed-morphology supernova remnant HB 9. A prior Ginga observation of this source detected a hard X-ray component above 4 keV and the origin of this particular X-ray component is still unknown. Our results demonstrate that the extracted X-ray spectra are best represented by a model consisting of a collisional ionization equilibrium plasma with a temperature of 0.1–0.2 keV (interstellar matter component) and an ionizing plasma with a temperature of 0.6–0.7 keV and an ionization timescale of >1×1011 cm−3 s (ejecta component). No significant X-ray emission was …

Teaching Cybersecurity To Students With Visual Impairments And Blindness, Jesse R. Hairston, Tania Williams, Derrick W. Smith Ed.D., Coms, William T. Sabados Ph.D., Steven Forney
Journal of Science Education for Students with Disabilities
This work showcases specific adaptations used to make cybersecurity accessible to high school students with visual impairments and blindness (VIB). The rapidly growing field of cybersecurity demands a diverse workforce; however, barriers exist which can deter students with disabilities from studying cybersecurity, let alone pursuing a career in the field. To help overcome this challenge, we launched the first GenCyber camp specifically developed and instructed for high school students with VIB in summer 2019. We created a unique learning environment by combining interactive instructional aids, accessible development environments, and innovative instructional strategies. With intent to show cybersecurity as a viable …
Groundings In Nature Mysticism And Adult Learning, Lee W. Nabb, Keith B. Armstrong
Groundings In Nature Mysticism And Adult Learning, Lee W. Nabb, Keith B. Armstrong
Faculty Research at Morehead State University
Historically, American education has functioned as the benefactor and disseminator of nature education, although that role has diminished in direct proportion to the diminutive presence of American natural landscapes. This withdrawal has led many to adulthoods typically devoid of a sense of place on the planet, as well as potentially limiting the ability to experience the sublime or mystical insights of life. This discussion investigates an experiential, interdisciplinary-action approach, used at Yellowstone National Park and a Canadian wilderness project, that supports and informs the reintegration of nature for the sublime or mystical development of adult students in higher education.
A Visual Typology Of Abandonment In Rural America: From End-Of-Life To Treading Water, Recycling, Renaissance, And Revival, Jason P. Holcomb
A Visual Typology Of Abandonment In Rural America: From End-Of-Life To Treading Water, Recycling, Renaissance, And Revival, Jason P. Holcomb
Faculty Research at Morehead State University
The contemporary American rural landscape reflects a mix of ongoing economic changes in agricultural land use, population change, and built environments. The mix depends on past and recent change which represent landscapes of memory and silence to those experiencing economic and demographic renaissance. We develop a typology of five stages that reflect the contemporary rural scene and conduct field transects in Northwest Iowa and Central Maine. Features of the dynamics in rural America are evident in photographs of residences, land use changes, and commercial structure. The study calls for additional studies on rural settlement populations, economies, and society in different …
