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. …

Acceleration Of Coronal Mass Ejection Plasma In The Low Corona As Measured By The Citizen Cate Experiment, Ignacio Birriel, Jennifer J. Birriel

Faculty Research at Morehead State University

The citizen Continental-America Telescopic Eclipse (CATE) Experiment was a new type of citizen science experiment designed to capture a time sequence of white-light coronal observations during totality from 17:16 to 18:48 UT on 2017 August 21. Using identical instruments the CATE group imaged the inner corona from 1 to 2.1 RSun with 1 43 pixels at a cadence of 2.1 s. A slow coronal mass ejection (CME) started on the SW limb of the Sun before the total eclipse began. An analysis of CATE data from 17:22 to 17:39 UT maps the spatial distribution of coronal flow velocities from about …

A Structural Equation Modeling Investigation Of The Theory Of Planned Behavior Applied To Accounting Professors’ Formal Enforcement Of Cheating Rules, Stephen S. Brigham

Faculty Research at Morehead State University

This study investigates factors that influence accounting professors’ formal enforcement of academic misconduct rules using the Theory of Planned Behavior (“TPB”) as a theoretical framework. Obtaining a better understanding of formal enforcement will inform efforts to improve it. We emailed survey requests to 8,663 accounting faculty in 35 countries and received a reasonably representative sample of 1,207 (13.9% response rate) complete surveys from 23 countries— exceeding sample-size requirements for structural equation modeling to test our TPB model, which explains 43.3% of the variance in Formal Enforcement Behavior and 52.4% of Intention, consistent with past TPB studies. Results indicate that of …

Comparative Gene Expression Profiling Between Optic Nerve And Spinal Cord Injury In Xenopus Laevis Reveals A Core Set Of Genes Inherent In Successful Regeneration Of Vertebrate Central Nervous System Axons, Kurt M. Gibbs

Faculty Research at Morehead State University

Background: The South African claw-toed frog, Xenopus laevis, is uniquely suited for studying differences between regenerative and non-regenerative responses to CNS injury within the same organism, because some CNS neurons (e.g., retinal ganglion cells after optic nerve crush (ONC)) regenerate axons throughout life, whereas others (e.g., hindbrain neurons after spinal cord injury (SCI)) lose this capacity as tadpoles metamorphose into frogs. Tissues from these CNS regions (frog ONC eye, tadpole SCI hindbrain, frog SCI hindbrain) were used in a three-way RNAseq study of axotomized CNS axons to identify potential core gene expression programs for successful CNS axon regeneration.

Results: Despite …

The Worsening Political Divide: Adult Education As Part Of The Cure, Lee W. Nabb, Fujuan Tan, Daryl R. Privott

Faculty Research at Morehead State University

The US is experiencing extreme social and political polarization not seen since the Civil War. This divisiveness is causing civil unrest and governmental dysfunction which threatens the stability of the nation. Four major causes of the current state are party realignment, the deregulation of news broadcasting, algorithmic personalization of electronic information, and an unknowing public. Adult education can and should be part of the remedy reducing or eliminating harmful polarization. Knowledge of authoritative systems is key to the solution. To promote such knowledge, adult educators can create practical and theoretical learning experiences about authoritative systems and incorporate such knowledge into …

Virtual Laboratory Of Industrial Scenarios For Training In The Areas Of Automation And Control, Jorge Alberto Ortega-Moody, William R. Grise

Faculty Research at Morehead State University

The incorporation of new technologies and technological developments in the area of automation and control requires constant training of the personnel involved in such area. The majority of this training begins in the laboratories of educational institutions and training centers for automation personnel. These laboratories are where theoretical knowledge gained in the classroom is applied. Unfortunately, being limited in infrastructure, the use of those laboratories, in the best case scenarios, are restricted to only some actuators and sensors. Industry training is another source in which individual companies have their own internal training programs led by experts in the field. However, …

The Effects Of Attending Annual Professional Conferences On The Personal Development Of International Faculty, Lee Nabb, Fujuan Tan

Faculty Research at Morehead State University

Especially given the current emphasis on internationalization and globalization, international faculty members constitute an important part of the overall faculty of higher education in the US and abroad. Personal as well as professional well-being is important in retaining international faculty. While annual professional conferences, by design, support and enhance professional development, little information exists as to the effect they have on personal development of international faculty members. This qualitative study was designed to provide foundational information on which to build further research as to the impact attending professional conferences have on the personal development and well-being of international higher education …

The Nuclear Environment Of The Nls1 Mrk 335: Obscuration Of The X-Ray Line Emission By A Variable Outflow, Dirk Grupe

Faculty Research at Morehead State University

We present XMM–Newton, NuSTAR, Swift, and Hubble Space Telescope observations of the Narrow-line Seyfert 1 galaxy Mrk 335 in a protracted low state in 2018 and 2019. The X-ray flux is at the lowest level so far observed, and the extremely low continuum flux reveals a host of soft X-ray emission lines from photoionized gas. The simultaneous UV flux drop suggests that the variability is intrinsic to the source, and we confirm this with broad-band X-ray spectroscopy. The dominance of the soft X-ray lines at low energies and distant reflection at high energies, is therefore due to the respective emission …

Three Propositions On The Education In Programming Languages, Euijin Kim

Faculty Research at Morehead State University

In the age of Big Data and artificial intelligence, programming languages are important for college students because the knowledge of programming can help them understand the modern technologies and make better decisions about the technologies. Nonetheless, programming language courses are not popular among college students. To attract more students, several suggestions have been made such as computational thinking (Wing, 2006) or application of the concept with easy programming approaches(Lye & Koh, 2014). These approaches, however, overlook the nature of programming (e.g., programming is about understanding computers). In this paper, a straight approach with three propositions on the education in programming …

The Devil In Recent American Law, L. Joe Dunman

Faculty Research at Morehead State University

Despite its secular aspirations, the American legal system is permeated by Christian and other religious ideas. One of the religious ideas that frequently appears in recent American law is the devil—the unholy antithesis of all that is good in the world. Called by many names, such as Satan, Lucifer, or the Antichrist, the devil is no stranger to the United States court system. The devil arises from the hot depths primarily in five contexts: (1) as a source of injury to reputation in defamation cases; (2) as a prejudicial invocation made during criminal trials to secure conviction, harshen sentences, or …

The Zboriv battlefield was explored by a Ukrainian-American archeological expedition led by author and archeologist Bogdan Strotsen. The studies lasted several years. The article covers the history of the Zboriv battle and reveals the main results of archaeological research. The results of the studies allowed to hypothesize the construction of elements of field fortifications and to interpret their localization in the territory.

Identifying Academically At-Risk Incoming Freshmen At A Private University In Uruguay: Psychometric Evaluation Of A Mathematics Diagnostic Test, Wilson J. Gonzalez-Espada

Faculty Research at Morehead State University

This study determined to what extent the mathematics diagnostic test (MDT) used at the Catholic University of Uruguay (CUU) was psychometrically appropriate. Also, after removing “red-flagged” items, the study measured to what extent MDT scores correlated with academic success. It was found that five MDT items (out of 30) did not meet the guidelines and were discarded. The score on the remaining items showed the highest correlation with the number of mathematics courses completed, confirming that students with low MDT-Revised scores might need additional academic support to remain in the engineering program.

Space Telescope And Optical Reverberation Mapping Project. Viii. Time Variability Of Emission And Absorption In Ngc5548 Based On Modeling The Ultraviolet Spectrum, Dirk Grupe

Faculty Research at Morehead State University

We model the ultraviolet spectra of the Seyfert 1 galaxy NGC5548 obtained with the Hubble Space Telescope during the 6 month reverberation mapping campaign in 2014. Our model of the emission from NGC 5548 corrects for overlying absorption and deblends the individual emission lines. Using the modeled spectra, we measure the response to continuum variations for the deblended and absorption-corrected individual broad emission lines, the velocity-dependent profiles of Lyα and C IV, and the narrow and broad intrinsic absorption features. We find that the time lags for the corrected emission lines are comparable to those for the original data. The …

The X-Ray Resolved Supernova Remnant S8 In The Dwarf Irregular Galaxy Ic 1613, Thomas G. Pannuti

Faculty Research at Morehead State University

We conducted an observation of the nearby irregular galaxy IC 1613 with the Chandra X-ray Observatory using the S3 chip of the ACIS with an effective exposure time of 49.9 ksec. The observation primarily targeted the extensive bubble and star formation region in the northeast quadrant of the galaxy. The only known supernova remnant (SNR) in IC 1613, S8, is also the galaxy’s most luminous X-ray source (LX(0.3-8 keV) 5 − 6×1036 erg s−1). We resolve the SNR with Chandra and compare its nearly circular X-ray morphology with H and radio images. We assign an upper limit on the luminosity …

Revealing The Nature Of Central Emission Nebulae In The Dwarf Galaxy Ngc185, Thomas G. Pannuti

Faculty Research at Morehead State University

Aims. In this paper we present new optical observations of the galaxy NGC185 intended to reveal the status of supernova remnants (SNRs) in this dwarf companion of the Andromeda galaxy. Previously, it was reported that this galaxy hosts one SNR. Methods. Our deep photometric study with the 2m telescope at Rozhen National Astronomical Observatory using narrow-band H and [S ii] filters revealed complex structure of the interstellar medium in the center of the galaxy. To confirm the classification and to study the kinematics of the detected nebulae, we carried out spectroscopic observations using the SCORPIO multi-mode spectrograph at the 6m …

Correlate Not Optional: Pp Sprouting And Parallelism In “Much Less” Ellipsis, Katy Carlson, Jesse A. Harris

Faculty Research at Morehead State University

Clauses that are parallel in form and meaning show processing advantages in ellipsis and coordination structures (Frazier et al. 1984; Kehler 2000; Carlson 2002). However, the constructions that have been used to show a parallelism advantage do not always require a strong semantic relationship between clauses. We present two eye tracking while reading studies on focus-sensitive coordination structures, an understudied form of ellipsis which requires the generation of a contextually salient semantic relation or scale between conjuncts. However, when the remnant of ellipsis lacks an overt correlate in the matrix clause and must be “sprouted” in the ellipsis site, the …

Females Serving As The Head Coach Of Competitive Elite Male Sports, Steve Chen, Christian Hensley

Faculty Research at Morehead State University

The recent coaching employment of Becky Hammon and Kathryn Smith in the NBA and NFL inspired the discussion of the potential of witnessing the first female head coach hired in men’s professional basketball and football. Despite the presence of female leaders in many business and political realms, there still seems to be a lack of gender equality in the employment of female administrators and coaches in the male-dominant sports. This study investigates how women were perceived as ideal head coaching candidates in a male dominant sport based on 132 student-athletes’ responses (70 males and 62 females). An exploratory factor analysis …

Comparing Absorbed Doses Of Properly And Improperly Collimated Abdominal Exposures, Ignacio Birriel

Faculty Research at Morehead State University

The purpose of this study was to calculate and compare the absorbed doses of properly and improperly collimated repeat examination exposures and to measure the anode heel effect to determine the difference in intensity between the cathode and anode ends of the x-ray beam. The investigators wanted to document the amount of additional radiation a patient receives due to improper collimation techniques and determine whether the difference in intensity between the anode and cathode ends of the x-ray beam was large enough to cause concern for increased patient absorbed doses for specific radiography examinations.

The Xmm-Newton/Hst View Of The Obscuring Outflow In The Seyfert Galaxy Mrk 335 Observed At Extremely Low X-Ray Flux, Dirk Grupe

Faculty Research at Morehead State University

The Seyfert galaxy Mrk 335 is known for its frequent changes of flux and spectral shape in the X-ray band that occurred during recent years. These variations may be explained by the onset of a wind that previous, noncontemporaneous high-resolution spectroscopy in X-ray and UV bands located at accretion disk scale. A simultaneous new campaign by XMM-Newton and the Hubble Space Telescope (HST) caught the source at a historically low flux in the X-ray band. The soft X-ray spectrum is dominated by prominent emission features and by the effect of a strong ionized absorber with an outflow velocity of (5–6)×103kms−1. …

Multiwavelength Study Of The X-Ray Bright Supernova Remnant N522-S48 In Ngc 522, Thomas G. Pannuti

Faculty Research at Morehead State University

We present a multiwavelength examination of the supernova remnant (SNR) S26 in the nearby galaxy NGC 300 using data from Chandra X-ray Observatory, XMM-Newton X-ray Observatory, Hubble Space Telescope (HST), the Very Large Array, and the Australia Telescope Compact Array. We simultaneously fit all of the available X-ray data with a thermal plasma model and find a temperature of 0.77±0.13 keV with a hydrogen column density of (9.7+6.4 −4.8)×1020 cm−2. HST imaging allows us to measure a semimajor axis of 0.78±0.10 arcsec (7.5±1.0 pc) and a semiminor axis of 0.69+0.14 −0.12 arcsec (6.7+1.2 −1.4 pc). This precise size helps to …

Faculty Research at Morehead State University

Aims. In this paper we discuss the radio continuum and X-ray properties of the so-far poorly studied Galactic supernova remnant (SNR) G5.9 + 3.1. Methods. We present the radio spectral energy distribution (SED) of the Galactic SNR G5.9 + 3.1 obtained with the MurchisonWidefield Array (MWA). Combining these new observations with the surveys at other radio continuum frequencies, we discuss the integrated radio continuum spectrum of this particular remnant. We have also analyzed an archival XMM-Newton observation, which represents the first detection of X-ray emission from this remnant. Results. The SNR SED is very well explained by a simple power-law …

Sky Brightness At Zenith During The January 2019 Total Lunar Eclipse, Jennifer J. Birriel, J. Kevin Adkins

Faculty Research at Morehead State University

Lunar eclipses occur during the full moon phase when the moon is obscured by Earth’s shadow. During these events, the night sky brightness changes as the full moon rises and then passes first into the penumbral and then the umbral shadow. We acquired sky brightness data at zenith using a Unihedron Sky Quality Meter during the 20–21 January 2019 total lunar eclipse as seen from Morehead, Kentucky. The resulting sky brightness curve shows an obvious signature when the moon enters the umbral (partial) eclipse phases and the total eclipse phase. During the total eclipse phase, the brightness curve is flat …
