    10 Reasons for Pre-medical Students to Consider an Internship
    (University Honors College, Middle Tennessee State University, 2023-12) Johnson, Gracie
    Internships are a critical step to take as an undergraduate student to become competitive for attending a graduate program or finding a career. There are two types of internships, paid and unpaid, which depend on the level of work being done and which field is being studied. It is found that pre-medical students tend to complete internships at a much lower rate than other undergraduates, and the goal of this creative project is to inform students about the benefits of medical internships. For this project, medical school admissions committees across the United States were interviewed to gain their insight on the significance of internships prior to attending medical school. The most significant reported reasoning was to gain exposure in medicine, which was followed by recognizing the intensity of the workplace prior to committing a lifetime to the field.

    24-h Fluid Kinetics and Perception of Sweat Losses Following a 1-h Run in a Temperate Environment
    ( 2013-12-10) O’Neal, Eric K. ; Caufield, Christina R. ; Lowe, Jordan B. ; Stevenson, Mary C. ; Davis, Brett A. ; Thigpen, Lauren K.
    This study examined 24-h post-run hydration status and sweat loss estimation accuracy in college age runners (men = 12, women = 8) after completing a 1-h self-paced outdoor run (wet bulb globe temperature = 19.9 ± 3.0 °C). Sweat losses (1353 ± 422 mL; 1.9% ± 0.5% of body mass) were significantly greater (pp less than 0.001) than perceived losses (686 ± 586 mL). Cumulative fluid consumption equaled 3876 ± 1133 mL (218 ± 178 mL during) with 37% of fluid ingested lost through urine voids (1450 ± 678 mL). Fluid balance based on intake and urine production equaled +554 ± 669 mL at 12 h and +1186 ± 735 mL at 24 h. Most runners reported euhydrated (pre-run urine specific gravity (USG) = 1.018 ± 0.008) with no changes (p = 0.33) at hours 12 or 24 when both genders were included. However, USG was higher (p = 0.004) at 12 h post-run for men (1.025 ± 0.0070 vs. 1.014 ± 0.007), who consumed 171% ± 40% of sweat losses at 12 h vs. 268% ± 88% for women. Most runners do not need intervention concerning between bout hydration needs in temperate environments. However, repeated USG measurements were able to identify runners who greatly under or over consumed fluid during recovery. Practitioners can use multiple USG assessments as cheap method to detect runners who need to modify their hydration strategies and should promote assessment of sweat losses by change in body mass, as runners had poor perception of sweat losses.

    2D Versus 3D
    (University Honors College, Middle Tennessee State University, 2023-05) Creter, Sidney
    This thesis goes through the history of 2D and 3D animation, and debates why 2D animation rarely receives 2D animated movies in theaters anymore. Along with this investigation of animation, I also created an animated short film in 2D and then recreated it in 3D to give direct comparisons between the two mediums. I cover topics such as why 2D dominates television even though it fails to come back to theaters, how Pixar led the 3D animation renaissance, and much more. This link leads to my 2D and 3D animated short films that will be compared in this essay. https://www.behance.net/gallery/167803433/Creative-Thesis-Project

    3-Linkage on the Projective Plane
    (Middle Tennessee State University, 2024) Jones, William ; Stephen’s, David C ; Ye, Dong ; Hart, James
    This thesis will provide some brief background information in the fields of Graph Theory and Algebraic Topology, a short history of linkage problems, and then a new result for 3-linked graphs embedded in the projected plane. First we will prove some Algebraic Topology results, importantly that a punctured projective plane is homoemorphic to an open m\"{o}bius band. Then in the Graph Theory section, we will provide a proof of Menger's Theorem. Next, we will discuss the results near to that of this thesis, including the 2-linkage theorem and an extremal function of $k$-linkage. Finally, we will describe one structure which ensures three-linkage on the projected plane. Three-linkage is defined as follows: a graph $G$ is three-linked if for any three pairs $(s_1,t_1)$, $(s_2,t_2)$, $(s_3,t_3)$ of vertices in $G$, there exist vertex disjoint paths $P_1,P_2,P_3$ such that for $1\leq i \leq 3$, $P_i$ links $s_i$ to $t_i$. In this paper we will provide a classification of 5 conected graphs embedded in the projected plane with face-width at least 5. Namely, we will prove that if $G$ is a 5-connected graph embedded in the projective plane with face width at least 5, then $G$ is three-linked if and only if $G-s_3$ has has a specific structure.

    3D PRINTING BODY PARTS: AN OVERVIEW OF HOW ADDITIVE MANUFACTURING IS SHAPING TISSUE ENGINEERING
    (Middle Tennessee State University, 2014-2-23) Cross, Grant ; Boraiko, Carol ; Engineering Technology
    Additive manufacturing, commonly referred to as 3D printing, is a manufacturing technique that emerged in the 1980 s mainly focused on engineering prototyping. Recent advances in the precision and cost of the techniques, as well as the widespread use of 3D modeling have increased 3D printing s scope of use from high-end engineering prototypes to a large variety of uses in manufacturing. 3D printing has been shown to improve the processing time, reduce waste, and increase the level of customization of certain products by eliminating the need for the specialty tooling and dies that are traditionally used in manufacturing. Additionally, the ability to physically print complex shapes based on a computer model has given rise to new products that would otherwise be simply impossible to create. The field of tissue engineering has taken advantage of this technology by printing organic cells and inorganic biomaterials with levels of control and precision that surpass previous production techniques. Furthermore, 3D printing allows for applications that can be customized on a case-by-case basis to fit the needs of individual patients. This review will overview the 3D printing-based techniques being used in tissue engineering, and discuss the current applications and challenges of this rapidly advancing field.

    4-Bit Cellular Automata Encryption Analysis
    (Middle Tennessee State University, 2017-07-13) Leitner, Dallas ; Salman, Karim ; Boles, Walter ; Sbenaty, Saleh ; Engineering Technology
    Forms of cellular automata have been used for decades in various niches. One such use is random number generation for data encryption. There are numerous ways that have been developed for this purpose, but they are largely centered on the use of the 3-bit rule space. While this rule space has been tested and proven to possess the desired traits, limiting CA to only the 3-bit rule space severely limits the potential for extreme levels of complexity. To that end, this research aims to explore the 4-bit rule space to find new potential rules that possess the desired level of complexity with the hope that the methods used can be applied to still greater rule spaces.

    A Baseline Study of the Impact of Faculty Awareness of Open Educational Resources on Faculty Perception of Open Educational Resources
    (Middle Tennessee State University, 2023) Haupt, Scott ; Rost, James ; Krahenbuhl, Kevin ; Godwin, Kim
    The importance of textbooks and other materials to the educational process cannot be overstated. Unfortunately, the prices on these vital learning materials have continued to grow steadily year over year (Hanson, 2021). Open educational resources (OER), which are “teaching, learning, and research materials that are either (a) in the public domain or (b) licensed in a manner that provides everyone with free and perpetual permission to engage in the 5R activities” (Creative Commons, 2020) have been offered by some educational pundits as a potential means of addressing these skyrocketing prices (Parks et al., 2020; Wiley, 2007). This nonexperimental, baseline study sought to analyze the relationship between faculty awareness of OER and their perceptions of OER as a viable alternative for or supplement to the more traditional publisher textbooks and resources. The survey instrument, created by Elder (2018) and administered by Elder et al. (2020), was used to collect demographic information, gauge current knowledge and awareness of OER, measure respondents’ awareness of the OER development support systems available to them, gauge interest in OER, assess familiarity with open licensing, and get a pulse on discipline-specific considerations from among the responding population. The researcher interpreted participants’ self-reported awareness and perception of OER through a primarily quantitative lens to maintain a narrow focus on these variables, though a fair amount of qualitative coding was required for various open-ended questions to allow for those parts to be included in the subsequent analysis in SPSS. Via a chi-square test of independence, the researcher was forced to reject the research hypothesis and was unable to determine if a significant relation existed between faculty awareness of OER and faculty perceptions of OER. This inability to make a determination likely resulted from (1) a low response rate; (2) a plurality of respondents who were already well-versed in the topic; and (3) a tendency for possible respondents who were less than familiar with the topic to shy away from completing the survey for fear of negatively impacting the data (though this last possibility can only be linked anecdotally). It was determined that additional research is warranted to assess the degree to which the findings of this study are generalizable to the university teaching population as a whole; a follow-up study with minor tweaks in methodology could address the issues that occurred during this study. Nevertheless, the results of this study can serve as a starting point for further research and communications.

    A Biographical Sketch of Julian Wehr (1898-1970): American Master of the Movable Book
    (James E. Walker Library, Middle Tennessee State University, 2024-02-27) Boehm, Alan ; Ziegler, Roy
    In the emerging popular and scholarly attention given to movable books, the name Julian Wehr often figures as an outstanding illustrator and paper engineer who in the 1940s and early 1950s published over 40 children's books notable for their appealing illustrations, but remarkable for their innovative pull-tab animations. Cleverly simple in design and widely imitated at the time, Wehr's approach to animated illustration revived a children's book format that had all but vanished from publishers' trade lists after the First World War because of production impracticalities. For although animated books had enjoyed considerable popularity in the late 1800s and early 1900s, they were typically lavish and expensive novelties that involved the manual assembly of an elaborate array of paper parts and minuscule hardware. By contrast, Wehr's animation technique--yielding pictorial movement as complex as any achieved by earlier methods--relied on only one or two pieces of paper and, moreover, his animated books were easily adapted to low-cost mass production. And mass-produced they were, for it is likely that upwards of nine million copies of Wehr's various titles--some translated into Spanish, French, German, and Icelandic--were sold in the United States, Canada, France, Great Britain, Spain, Germany, Switzerland, Iceland, and elsewhere. Accordingly, we offer in this essay a brief biographical sketch of Wehr's life and career. It is based chiefly on interviews conducted across the spring, summer, and autumn of 2001 with his four children, Camilla West Molinari (Wehr's daughter from his first marriage), David Wehr, Paul Wehr, and Jeanine Wehr Jones (Wehr's sons and daughter from his second marriage). The Wehr children also have made available to us their father's art work, letters, and other materials.

    A Brief History of the Preventorium: Architectural and Other Challenges of Preserving the Children’s Preventorium
    (Middle Tennessee State University, 2024) Brickel, Samantha ; Van West, Caroll ; Pruitt, Lisa
    Beginning in the 1970s, with assessments increasing in number in the 1980s and 1990s, historic preservationists have studied sanitoriums, small and large, across the United States. Almost no attention has been given to preventoriums, which were institutions that housed those with latent or bone and joint tuberculosis. These institutions represent a significant period of American medicine and understanding this resource’s significance was the primary purpose of the thesis. It combines both architectural survey and primary resources to make the case for the future preservation and interpretation of preventoriums.

    A COBALT OXIDE CARBON NANOTUBE COMPOSITE FOR DOPAMINE DETECTION
    (Middle Tennessee State University, 2018) Kader, Mohammad Salauddin ; Chemistry
    Dopamine (DA) is a catecholamine and performs as a neurotransmitter in the human body. Dopamine plays an important role in the process of many biological networks. Research showed that unusual amounts of DA can cause several neurological diseases such as Parkinson’s disease, schizophrenia, and other mental disorder. Cobalt oxide (CoO) particles were tethered to carboxylic-acid-functionalized multi-walled carbon nanotubes (COOH-MWNT) using sonication. The resulting composite (CoO/COOH-MWNT) was applied to glassy carbon electrodes for detecting DA within the 0.5-5 µM range and 10-100 µM range. Current versus concentration was measured using cyclic voltammetry. Different parameters such as loading, pH and sonication times (0 to 60 min) were varied to optimize current response. Good selectivity was found against uric acid and ascorbic acid. The (CoO/COOH-MWNT) composite was characterized by attenuated total reflection infrared spectroscopy (ATR-IR), Raman spectroscopy, Transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS).

    A comparative study of stress physiology in the common watersnake (Nerodia sipedon), the diamondback watersnake (Nerodia rhombifer), and the queen snake (Regina septemvittata).
    (Middle Tennessee State University, 2018-04-13) McCallie, Katharine Louise ; Klukowski, Matthew ; Cobb, Vincent ; Otter, Ryan ; Biology
    Vertebrates respond to stressors in part by increasing the secretion of glucocorticoids from the adrenal gland. Both intrinsic and extrinsic factors (e.g., age, sex, season) have been shown to influence glucocorticoid secretion within a species, but understanding of species differences in glucocorticoid secretory patterns is limited. In this study, I examined corticosterone, progesterone, and testosterone levels in the common watersnake (Nerodia sipedon), the diamondback watersnake (Nerodia rhombifer), and the queen snake (Regina septemvittata) at a capture baseline and in response to an acute 30 minute confinement stress. I also examined the same steroids in Nerodia sipedon subjected to three weeks of laboratory housing, a known chronic stressor. All three species exhibited elevated corticosterone in response to acute stress but baseline and post- stress levels varied among species. Overall, Nerodia sipedon and Nerodia rhombifer exhibited similar corticosterone and testosterone levels both at capture baseline and after 30 minutes of confinement stress. Regina septemvittata had substantially higher corticosterone levels than the two Nerodia species. Nerodia sipedon subjected to chronic stress showed no significant changes in corticosterone levels from the baseline to post-lab housing, suggesting downregulation of the hypothalamo-pituitary-adrenocortical axis and glucocorticoid production.

    A Comparative Study on Two Strategies for Distributed Classification
    (Middle Tennessee State University, 2018-05-30) Xu, Honglan ; Wu, Qiang ; Hong, Don ; Liu, Yeqian ; Green, Lisa ; Basic & Applied Sciences
    Distributed learning is an effective tool to process big data. An easy and effective distributed learning approach is the divide and conquer method. It first partitions the whole data set into multiple subsets. A base learning algorithm is then applied to each subset. Finally the results from these subsets are coupled together. In the classification setting, many classification algorithms can be used in the second stage. Typical ones include the logistic regression and support vector machines. For the third stage, both voting and averaging can be used as the coupling strategies. In this thesis, empirical studies are done to thoroughly compare the effectiveness of these two coupling strategies. Averaging is found to be more effective in most scenarios.
