First Record Of Fungal Diversity In The Tropical And Warm-Temperate Middle Miocene Climate Optimum Forests Of Eurasia, Jennifer M.K. O'Keefe
First Record Of Fungal Diversity In The Tropical And Warm-Temperate Middle Miocene Climate Optimum Forests Of Eurasia, Jennifer M.K. O'Keefe
Faculty Research at Morehead State University
The middle Miocene Climate Optimum (MMCO) was the warmest interval of the last 23 million years and is one of the best analogs for proposed future climate change scenarios. Fungi play a key role in the terrestrial carbon cycle as dominant decomposers of plant debris, and through their interactions with plants and other organisms as symbionts, parasites, and endobionts. Thus, their study in the fossil record, especially during the MMCO, is essential to better understand biodiversity changes and terrestrial carbon cycle dynamics in past analogous environments, as well as to model future ecological and climatic scenarios. The fossil record also …
Factors Associated With The Underrepresentation Of Female Head Coaches In Intercollegiate Athletics, Steve Chen, Lauren Smith, Chloe Whitlock
Factors Associated With The Underrepresentation Of Female Head Coaches In Intercollegiate Athletics, Steve Chen, Lauren Smith, Chloe Whitlock
Faculty Research at Morehead State University
The purpose of this study was to examine the perceived barriers, stereotypes, and workplace challenges that contributed to the underrepresentation of female head coaches in intercollegiate athletics. One-hundred-twenty-four current collegiate coaches affiliated with three NCAA conferences completed their responses through an online survey. A 26-item self-created survey was implemented to identify perceived attributes and barriers which impact the females’ involvement in the coaching profession. The results yielded four constructs of attributes and three types of barriers that affected female coaches’ success for job obtainment and career advancement. Unlike the older experienced coaches, young and less experienced coaches tended to value …
The Eddington Ratio-Dependent ‘Changing Look’ Events In Ngc2992, Dirk Grupe
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
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 …
A Systematic Study Of Photoionized Emission And Warm Absorption Signatures Of The Nls1 Mrk 335, Dirk Grupe
A Systematic Study Of Photoionized Emission And Warm Absorption Signatures Of The Nls1 Mrk 335, Dirk Grupe
Faculty Research at Morehead State University
We present an analysis of all the archival high resolution spectra of the Narrow-line Seyfert 1 galaxy Mrk 335 obtained with Reflection Grating Spectrometer (RGS) on board XMM-Newton. The spectra show rich emission and absorption features in low and intermediate flux intervals. We model the emission lines with the pion_xs grid and try to find any possible correlation between the properties of the emitting gas and the source flux. Current data does not allow detailed trace of the response of the line emitting gas to the X-ray flux of Mrk 335, but the flux of the X-ray lines is significantly …
Modeling The Multiwavelength Variability Of Mrk 335 Using Gaussian Processes, Dirk Grupe
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 …
Identification Of Phosphorus Index Improvements Through Model Comparisons Across Topographic Regions In A Small Agricultural Watershed In Vermont, Amy S. Collick
Faculty Research at Morehead State University
Many U.S. states require farmers to evaluate the risk of P loss from farm fields using P site assessment tools, such as the Phosphorus Index (P-Index). The simplicity of the P-Index allows for users with various backgrounds to utilize the tool; however, the P-Index may be limited in its ability to reliably predict P losses across variable farm terrain, for instance where saturation-excess runoff generation dominates. The objective of this study was to identify potential improvements that could be made to the Vermont P-Index (VT P-Index) by comparing VT P-Index predictions of P loss with those of a model that …

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 …

Cleaning Up China's Air: The Effectiveness Of The Eep Plan In Beijing, James R. Masterson
Faculty Research at Morehead State University
China’s economy has developed rapidly in the past 40 years since the reform and opening up. However, China’s irrational economic structure, low efficiency of resource utilization and serious environmental pollution have become important factors restricting the long-term healthy development of China’s economy. More importantly, pollution issues in China seriously affect the development of the regime due to public concerns in terms of health issues. In 2014, senior government officials said publicly that China would “declare war on pollution.” Since then, air pollution has improved to a certain extent, with PM 2.5 levels falling 23.6 percent from 2013 to 2015, but …

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
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 …
Focus Attracts Attachment, Kathryn Carlson, David Potter
Focus Attracts Attachment, Kathryn Carlson, David Potter
Faculty Research at Morehead State University
There is growing evidence that pitch accents as well as prosodic boundaries can affect syntactic attachment. But is this an effect of their perceptual salience (the Salience Hypothesis), or is it because accents mark the position of focus (the Focus Attraction Hypothesis)? A pair of auditory comprehension experiments shows that focus position, as indicated by preceding wh-questions instead of by pitch accents, affects attachment by drawing the ambiguous phrase to the focus. This supports the Focus Attraction Hypothesis (or a pragmatic version of salience) for both these results and previous results of accents on attachment. These experiments show that information …

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 …

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

A Space Of One’S Own: Houselot Size Among The Ancient Maya, Timothy Hare
Faculty Research at Morehead State University
This paper uses new data from lidar mapping to explore variation in the size of ancient Maya houselots. The amount of space available to households has important implications for subsistence, craft activities, social relations, and more. Comparisons of houselot data from three large cities (Coba, Mayapan, and Chunchucmil) and one rural area (southwestern Quintana Roo) show significant differences in houselot size across the four case studies. Site size has no effect when comparing across case studies although patterns of variation do emerge within the case studies. Of the major factors explored–wealth, household size, distance from site core, availability of open …
Insights Into Past Land-Use And Vegetation Change In The Llanos De Moxos (Bolivia) Using Fungal Non-Pollen Palynomorphs, Jennifer M.K. O'Keefe
Insights Into Past Land-Use And Vegetation Change In The Llanos De Moxos (Bolivia) Using Fungal Non-Pollen Palynomorphs, Jennifer M.K. O'Keefe
Faculty Research at Morehead State University
Here we document a 1000-year fungal record from the raised-field region of the Llanos de Moxos, a seasonally inundated forest-savanna mosaic in the Bolivian Amazon. Fungi are extremely sensitive to changes in vegetation due to their close relationship with the local environment, providing a useful proxy for past local vegetation and land-use change. Here the remains of fungal non-pollen palynomorphs (NPPs) are identified from a sediment core taken from Laguna El Cerrito. A multivariate constrained ordination is used to extract relationships between the fungal NPP types and environmental gradients, specifically, tree cover, near-shore vegetation, crop cultivation, burning and local sediment …

Glow Sticks: Spectra And Color Mixing Revisited, Jennifer Birriel
Glow Sticks: Spectra And Color Mixing Revisited, Jennifer Birriel
Faculty Research at Morehead State University
A previous TPT article discussed using glow sticks to demonstrate color mixing by comparing the spectra of red, green, and blue glow sticks to those of yellow and magenta glow sticks.1 More recently, a paper in the Journal of Chemical Education describes a method to separate glow stick dyes using chromatography with chalk and a solvent of acetone or alcohol.2 This method, while a valuable experience in a chemistry class, requires the glow stick to be opened. Care must be taken by preparers to remove glass shards, and participants are exposed to possible skin irritants. Here we propose a non-destructive, …

Faculty Research at Morehead State University
The prominent rise of social networks within the past decade have become a gold mine for data mining operations seeking to model the real world through these virtual worlds. One of the most important applications that has been proposed is utilizing information generated from social networks as a supplemental health surveillance system to monitor disease epidemics. At the time this research was conducted in 2020, the COVID- 19 virus had evolved into a global pandemic, forcing many countries to implement preventative measures to halt its expanse. Health surveillance has been a powerful tool in placing further preventative measures, however it …
Asassn-14ko Is A Periodic Nuclear Transient In Eso 253-G003, Dirk Grupe
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 …
