The Eddington Ratio-Dependent ‘Changing Look’ Events In Ngc2992, Dirk Grupe

Faculty Research at Morehead State University

We present an analysis of historical multi-wavelength emission of the Changing Look (CL) Active Galactic Nucleus (AGN) in NGC 2992, covering epochs ranging from 1978 to 2021, as well as new X-ray and optical spectra. The galaxy presents multiple Seyfert type transitions from type 2 to intermediate-type, losing and regaining its H𝛼 BEL recurrently. In X-rays, the source shows intrinsic variability with the absorption corrected luminosity varying by a factor of 40. We rule-out tidal disruption events or variable obscuration as causes of the type transitions, and show that the presence and the flux of the broad H𝛼 emission line …

Radio Continuum Sources Behind The Large Magellanic Cloud, Thomas G. Pannuti

Faculty Research at Morehead State University

We present a comprehensive multi-frequency catalogue of radio sources behind the Large Magellanic Cloud (LMC) between 0.2 and 20 GHz, gathered from a combination of new and legacy radio continuum surveys. This catalogue covers an area of 144 deg2 at angular resolutions from 45 arcsec to 3 arcmin. We find 6 434 discrete radio sources in total, of which 3 789 are detected at two or more radio frequencies. We estimate the median spectral index (; where 𝑆𝑣 𝜈) of 𝛼 = 09 and mean of 088 0.48 for 3 636 sources detected exclusively at two frequencies (0.843 and 1.384 …

Modeling The Multiwavelength Variability Of Mrk 335 Using Gaussian Processes, Dirk Grupe

Faculty Research at Morehead State University

The optical and UV variability of the majority of active galactic nuclei may be related to the reprocessing of rapidly changing X-ray emission from a more compact region near the central black hole. Such a reprocessing model would be characterized by lags between X-ray and optical/UV emission due to differences in light travel time. Observationally, however, such lag features have been difficult to detect due to gaps in the lightcurves introduced through factors such as source visibility or limited telescope time. In this work, Gaussian process regression is employed to interpolate the gaps in the Swift X-ray and UV lightcurves …

Information Technology Creativity And Economic Growth: A Case Of Korea, Hiawook Choi, Hae-Yeon Choi

Faculty Research at Morehead State University

This paper examines the contributing factors of information technology (IT) creativity and whether IT creativity can explain the economic growth in Korea. We empirically test college students’ perception and attitudes on educational quality, work environment, social preparedness on tolerance, and government-initiated IT policy. We also test whether creative capital theory, which states creativity as the major driver ofregional and national economic development– is working in Korea. We apply structural equation modeling (SEM) to analyze the survey data collected from college students in five different regions in Korea. SEM analysis indicates that all endogenous constructs, except education quality, provide a statistically …

Perceptions On Implementing A Comprehensive Athletic Website And Online Streaming Service For Kentucky High Schools, Steve Chen, Adrienne Hall

Faculty Research at Morehead State University

Student participation in interscholastic athletics reached record levels in 2019-20 for the third consecutive year in Kentucky (KHSAA, 2020). Sport marketers have strongly advocated social media as a powerful and effective tool to promote sporting events at all levels. However, existing studies rarely focus on the trend for promoting interscholastic sports through social media platforms. This study examined the potential of an interactive website and online streaming service focusing on interscholastic sports may provide to high schools in Kentucky. After evaluating more than 102 high school athletic websites, the authors found schools were in need to improve the current website …

With news media coverage of free dating app horror stories of serial rapists and undergraduates reporting having been lied to in previous relationships, 157 undergraduate students at Morehead State University and East Carolina University completed an anonymous, voluntary 31 item online survey to assesses vetting/background checks on potential/current romantic partners. Over three-fourths (75.5%) of the respondents reported that they had Facebook/social media stalked a potential romantic partner with about a quarter reporting having conducted a background check on someone they were considering meeting or were already dating. Focus groups were also conducted with 23 undergraduate students who provided further insight …

Examining Sources And Pathways Of Phosphorus Transfer In A Ditch-Drained Field, Amy Collick

Faculty Research at Morehead State University

Understanding the processes that mobilize and transport dissolved phosphorus (P) during storms is critical to managing P in flat landscapes with open ditch drainage and legacy soil P. In this study, we used routine baseflow monitoring and intensive storm sampling at a ditch-drained site on Maryland’s Lower Eastern Shore (July 2017–September 2018) to assess whether concentration–discharge (C-Q) relationships and chemical and isotopic hydrograph separation could provide insight into the processes that mobilize and transport dissolved P in ditch drainage. Using a segmented regression model, we determined that long-term C-Q relationships for dissolved P differed above and below a discharge threshold …

Predicting The Mechanism And Products Of Co2 Capture By Amines In The Presence Of H2o, Zachary R. Lee

Faculty Research at Morehead State University

An extensive correlated molecular orbital theory study of the reactions of CO2 with a range of substituted amines and H2O in the gas phase and aqueous solution was performed at the G3(MP2) level with a self-consistent reaction field approach. The G3(MP2) calculations were benchmarked at the CCSD(T)/CBS level for NH3 reactions. A catalytic NH3 reduces the energy barrier more than a catalytic H2O for the formation of H2NCOOH and H2CO3. In aqueous solution, the barriers to form both H2NCOOH and H2CO3 are reduced, with HCO3 − formation possible with one amine present and H2NCOO− formation possible only with two amines. …

Marco: Solar Powered Autonomous Robotic Unmanned Surface Vehicle, Thomas G. Pannuti

Faculty Research at Morehead State University

Autonomous sailboats have demonstrated that a robot could potentially perform long-term ocean monitoring and traveling. However, self-operating sailboats in the past had sails, which could lead to issues caused by tipping and heeling too much, and were not fully solar powered, which leads to short power endurance issues. Energy efficient and low cost autonomous robotic unmanned surface vehicle, named MARCo (Marine Autonomous Robotic Communicator), was programmed, developed and tested throughout the year 2018 in a public, co-educational university in Morehead, Kentucky. An off-grid solar system, comprised of 3x 20-Watt 12-Volt panels and a 12-Volt charge controller, was designed, constructed, and …

Predicting The Behavior Of Reinforced Concrete Columns Confined By Fiber Reinforced Polymers Using Data Mining Techniques, Heba Elgazzar

Faculty Research at Morehead State University

Fiber Reinforced Polymer (FRP) usage to wrap reinforced concrete (RC) structures has become a popular technology. Most studies about RC columns wrapped with FRP in literature ignored the internal steel reinforcement. This paper aims to develop a model for the axial compressive strength and axial strain for FRP confined concrete columns with internal steel reinforcement. The impact of FRP, Transverse, and longitudinal reinforcement is studied. Two non-destructive analysis methods are explored: Artificial Neural Networks (ANNs) and Regression Analysis (RA). The database used in the analysis contains the experimental results of sixty-four concrete columns under the compressive concentric load available in …

Asassn-14ko Is A Periodic Nuclear Transient In Eso 253-G003, Dirk Grupe

Faculty Research at Morehead State University

We present the discovery that ASASSN-14ko is a periodically flaring active galactic nucleus at the center of the galaxy ESO 253-G003. At the time of its discovery by the All-Sky Automated Survey for Supernovae (ASAS-SN), it was classified as a supernova close to the nucleus. The subsequent 6 yr of V- and g-band ASAS-SN observations revealed that ASASSN-14ko has nuclear flares occurring at regular intervals. The 17 observed outbursts show evidence of a decreasing period over time, with a mean period of P0 = 114.2 ± 0.4 days and a period derivative of P = -0.0017  0.0003. The most …

Physical Activity Promotion And Support: Meeting Caregivers’ Unique Needs, Gina B. Gonzalez

Faculty Research at Morehead State University

The benefits of engaging in regular physical activity are extensive and can have a profound positive effect on one’s overall health (1). Numerous recent scientific reviews (2) further underscore the important role physical activity plays in achieving optimal health and preventing noncommunicable disease. For example, physical activity reduces risk of several types of cancer (3), ischemic heart disease, ischemic stroke, heart failure, and premature mortality (4). Among older adults, physical activity can improve cognitive functioning (5), reduce the risk of fall-related injuries, and delay the loss of physical function and mobility (6). According to Healthy People 2030, the nation’s health …

On The Value Of In-Class Lecture: Evidence From Introductory Corporate Finance Classes, Chien Chih Peng

Faculty Research at Morehead State University

This study examines whether the availability of in-class lectures can lead to difference in student peiformance between face-to-face and online introductory corporate finance classes. The ordinary least squares regression model is employed to analyze a sample of 284 students at a four-year state university in the Appalachian region. The results show that when assessed online, students receiving in-class lectures in face-to-face classes peiform significantly better than those receiving narrated PowerPoint slides on study aids in online classes. In addition, the results show that student's major and educational experience are significant determinants of student performance.

Space Telescope And Optical Reverberation Mapping Project. Ix. Velocity–Delay Maps For Broad Emission Lines In Ngc5548, Dirk Grupe

Faculty Research at Morehead State University

In this contribution, we achieve the primary goal of the active galactic nucleus (AGN) STORM campaign by recovering velocity–delay maps for the prominent broad emission lines (Ly, C IV, He II, and H) in the spectrum of NGC5548. These are the most detailed velocity–delay maps ever obtained for an AGN, providing unprecedented information on the geometry, ionization structure, and kinematics of the broad-line region. Virial envelopes enclosing the emission-line responses show that the reverberating gas is bound to the black hole. A stratified ionization structure is evident. The He II response inside 5–10 light days has a broad single-peaked velocity …

“It Doesn’T Feel Like A Conversation”: Digital Field Experiences And Preservice Teachers’ Conceptions Of Writing Response, Alison Heron-Hruby, James S. Chisholm, Andrea R. Olinger

Faculty Research at Morehead State University

Research shows that preservice English teachers (PSETs) lack opportunities to respond to student writing and that they may view student writing through a deficit lens. To address this need, the authors developed the Writing Mentors (WM) program, a digital field placement that gave PSETs experience providing feedback to high school writers. In this analysis, we examine how PSETs’ views of response were shaped by their digital interactions with high school writers. The challenges of interacting asynchronously created opportunities for PSETs to identify limitations in the mode of communication, propose approaches to providing feedback, and reflect on how teacher feedback can …

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 …

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

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 dierent …

A Corepressor Participates In Lexa-Independent Regulation Of Error-Prone Polymerases In Acinetobacter, Janelle M. Hare, Alison N. Grice, Megan A. Peterson

Faculty Research at Morehead State University

The DNA damage response of the multidrug-resistant pathogen Acinetobacter baumannii, which induces mutagenic UmuD′2C error-prone polymerases, differs from that of many bacteria. Acinetobacter species lack a LexA repressor, but induce gene transcription after DNA damage. One regulator, UmuDAb, binds to and represses the promoters of the multiple A. baumannii ATCC 17978 umuDC alleles and the divergently transcribed umuDAb and ddrR genes. ddrR is unique to the genus Acinetobacter and of unknown function. 5' RACE (rapid amplification of cDNA ends) PCR mapping of the umuDAb and ddrR transcriptional start sites revealed that their −35 promoter elements overlapped the UmuDAb binding site, …

Life And Death In The Chicxulub Impact Crater: A Record Of The Paleocene–Eocene Thermal Maximum, Jennifer M. O'Keefe

Faculty Research at Morehead State University

Thermal stress on the biosphere during the extreme warmth of the Paleocene–Eocene Thermal Maximum (PETM) was most severe at low latitudes, with sea surface temperatures at some localities exceeding the 35 C at which marine organisms experience heat stress. Relatively few equivalent terrestrial sections have been identified, and the response of land plants to this extreme heat is still poorly understood. Here, we present a new record of the PETM from the peak ring of the Chicxulub impact crater that has been identified based on nannofossil biostratigraphy, an acme of the dinoflagellate genus Apectodinium, and a negative carbon isotope excursion. …
