Women’S Suffrage Is “Nothing Less Than Treasonable:” An Analysis Of Rural Women And Their Group Activism In The Women’S Suffrage Movement In The Jackson Purchase Area, 1838-1940, Ashleigh Deno

Honors College Theses

The 1910s was a decade characterized by technological advancement, World War I, and a global movement for women’s suffrage, which would eventually culminate with legislation, most notably the 19th Amendment in the United States. In the United States, women staged protests throughout the country and were known to stand outside of the White House with taunting signs for President Woodrow Wilson to read. This movement came to the United States from other parts of the globe, particularly Britain, and suffragists from other countries were known to travel to the States to give presentations and provide guidance to suffragists on this …

Pyrococcus Horikoshii Rada Intein Site Selection, Noah Stallins

Honors College Theses

Inteins are protein segments interrupting polypeptides with the unique ability to excise from the host protein and link flanking protein fragments (exteins) to form a functional protein. Many of these proteins are involved in crucial processes such as DNA replication, DNA recombination, and DNA repair. The functionality of these elements in nature and applications in biotechnology necessitates the study of inteins. Pyrococcus horikoshii (Pho) provides an array of inteins to study, with a total of nine different proteins possessing inteins. Among the nine total inteins, the DNA repair and recombination protein RadA gained interest due to the speed …

Relative Size Underlies Alternative Morph Development In A Salamander, Michael P. Moore, Joseph H. K. Pechmann, Howard H. Whiteman

Faculty & Staff Research and Creative Activity

Size thresholds commonly underlie the induction of alternative morphological states. However, the respective importance of absolute and relative size to such thresholds remains uncertain. If absolute size governs expression, morph frequency should differ among environments that influence absolute sizes (e.g. resources, competition), and individuals of the same morph should have similar average sizes across environments. If relative size determines expression, the frequency of each morph may not differ among environments, but morphs within each environment should differ in size relative to one another. We tested these predictions in a salamander (Ambystoma talpoideum) that develops into either a terrestrial …

Site Selection Of Pyrococcus Horikoshi Rada Intein, Madison Paige White

Honors College Theses

Inteins are polypeptides translated within host proteins that undergo an autocatalytic protein splicing reaction to join the flanking sequences, termed N- and C- extiens. Long considered molecular parasites, recent work has demonstrated that protein splicing can be regulated by environmental signals, representing an exciting new form of post-translational regulation. A landmark example comes from the homologous recombinase RadA of the archaeon Pyrococcus horikoshii, which splices in response to substrate single-stranded DNA. Interestingly, while the P. horikoshii RadA intein splices efficiently when inserted into foreign exteins under all conditions tested, splicing is inhibited in native exteins in absence of ssDNA. In …

Occurrence And Mass Loading Of Synthetic Opioids, Synthetic Cathinones, And Synthetic Cannabinoids In Wastewater Treatment Plants In Four U.S. Communities, Catherine O'Rourke, Bikram Subedi

Faculty & Staff Research and Creative Activity

A few new psychoactive substances (NPS) that mimic the effects of controlled neuropsychiatric and illicit drugs have been forensically identified in the U.S. Wastewater-based epidemiology (WBE) can provide a comprehensive and more cost- and time-effective method of determining the prevalence of NPSs in communities. In this study, an analytical method capable of simultaneous determination of trace-level 40 NPS residues (synthetic opioids, synthetic cannabinoids, synthetic cathinones, piperazines, indole, and amphetamine) in wastewater was developed and validated. The developed analytical method was utilized to determine the occurrence of NPSs in four rural communities in southern Illinois. Nine NPSs (carfentanil, furanyl fentanyl, methoxyacetyl …

Reversible Inhibition Of Mycobacterial Dnab Protein Splicing By Zinc, Gabrielle Hardison

Honors College Theses

Inteins are emerging as post-translational regulatory elements, undergoing conditional protein splicing in response to a variety of environmental cues. Inteins are seamlessly removed by self-splicing from exteins, or flanking portions of the host protein, which they interrupt. DnaB of Mycobacterium smegmatis, a helicase essential for replication, harbors two inteins known as DnaBi1 and DnaBi2, each with discrete structural characteristics and insertion positions. DnaBi1 was used here to design a reporter system which links splicing with resistance to the antibiotic kanamycin. We built a construct that strictly requires catalytically active DnaBi1 for survival in the presence of kanamycin and used …

Evaluating An Ordinal Output Using Data Modeling, Algorithmic Modeling, And Numerical Analysis, Martin Keagan Wynne Brown

Murray State Theses and Dissertations

Data and algorithmic modeling are two different approaches used in predictive analytics. The models discussed from these two approaches include the proportional odds logit model (POLR), the vector generalized linear model (VGLM), the classification and regression tree model (CART), and the random forests model (RF). Patterns in the data were analyzed using trigonometric polynomial approximations and Fast Fourier Transforms. Predictive modeling is used frequently in statistics and data science to find the relationship between the explanatory (input) variables and a response (output) variable. Both approaches prove advantageous in different cases depending on the data set. In our case, the data …

Paleofloods And Landform Development Influence Carbon Storage In A Humid-Subtropical River Valley, Christopher Lance Stewart

Murray State Theses and Dissertations

Floodplains can store large amounts of soil organic carbon (SOC) despite covering a small fraction of the global land area. Since these valley-bottom landforms build through the action of flooding, the century to millennial-scale record of overbank deposition could be important in understanding controls on deep (>30 cm) SOC storage. Yet, the influence of flood history and landform development on carbon content is surprisingly not well known. I use a combined geological and pedological approach to characterize the sedimentation, soil development, and SOC of fluvial terraces along an impounded reach of the humid-subtropical Tennessee River valley, U.S.A. The standardized …

Population Demographics Of Silver Carp Hypophthalmichthys Molitrix In Kentucky Lake, Allison M. Lebeda

Murray State Theses and Dissertations

Invasive species continue to threaten aquatic ecosystems in the United States. Silver Carp Hypophthalmichthys molitrix have successfully infiltrated much of the Mississippi River Basin, including Kentucky Lake – a large reservoir located on the Tennessee River in Western Kentucky. Although Silver Carp have been present in Kentucky Lake for at least a decade, until recently, very little was known about the population, how often successful reproduction is occurring, or the environmental conditions that facilitate strong year-classes. Hence, it is difficult for managers to predict the potential impact of Silver Carp on native species. Silver Carp were collected from Kentucky Lake …

Political Centrism, Perspective Taking, And Outgroup Derogation: An Integrated Model, David Kesler

Murray State Theses and Dissertations

Abstract

The relationship between perspective taking abilities, political centrism, and outgroup derogation is not defined at this time. While previous research has demonstrated a negative relationship between political centrism and outgroup derogation (Van Prooijen, Krouwel, Boiten, & Eendebak, 2015), the relationship between the other variables is unclear. Therefore, the current study sought to measure the relationship between (1) perspective taking abilities and political centrism, (2) perspective taking and outgroup derogation, (3) political centrism and outgroup derogation and lastly, (4) whether the relationship between perspective taking abilities and political outgroup derogation would be mediated by an individual's level of political centrism.
