Pu Foams

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Thermal conductivity [subscript] of a rigid polyurethane (PU) foam was successfully simulated, during which the impact of index of isocyanate, mixing speed, and the amount of physical blowing agent was characterized by a heat flow meter for [subscript], and a pycnometer for the foam density and closed cell content. Besides, heat capacities (𝐶𝑃) of most common polyols and isocyanate in making PU foams were experimentally measured. Then a general formula was created for using in a Matlab code to boost efficiency of simulating the reaction temperature. This work laid the groundwork for modeling the viscosity, reaction rates, and concentrations of reactants, etc. Prior to this publication, it was assumed in our simulation code that 𝐶𝑃 was a function of rising temperature by a slope of 0.1% per one degree for any polyols and isocyanate. In addition, a potential way to help undergraduates to achieve analysis, evaluation, and creation levels of learning in polymer and chemical reaction engineering course was presented.

The Relationship

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This study is an examination of the relationship between political connections and the undertaking of major firm events. In our first essay, presented in Chapter 3, we examine the impact politically connected appointments have on firm acquisition behavior. Using proxy statements, we create a unique database of politically connected bidders and merger targets. We find that bidders who hire connected individuals to the board or management team are more likely to avoid merger litigation. Connected bidders make more bids after the appointment. These firms also bid on larger targets. We determine there is a positive relation between the control premium and the relative of the target's connections. Connected acquirers have superior post-merger accounting performance, particularly when they acquire a connected target firm. In the second essay, presented in Chapter 4, we examine the relationship between political connections of private firms and the initial public offering process. Using registration statement information, we create a unique database of politically connected IPO firms. We find that political connections are substitutes to high-quality underwriters and big four auditors. Politically connected firms manage earnings more highly upward than non-connected firms prior to the public offering. Politically connected firms also exhibit less underpricing than non-connected firms. Politically connected IPO firms also have superior post-IPO returns relative to non-connected IPO firms.

The Impact

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The shedding of plant organs is known as abscission. Floral abscission in Arabidopsis is regulated by two related receptor[negation symbol]-like protein kinases (RLKs), HAESA and HAESA[negation symbol-like 2 (HAE/HSL2). Double mutants of HAE/HSL2 are completely defective in abscission and retain sepals, petals, and stamen indefinitely. We have utilized genetic suppressor screens of hae hsl2 mutant to identify additional regulatory mechanisms of floral abscission. We have uncovered a series of gain-of-function alleles of the receptor-like protein kinase gene SERK1, as well as loss of function alleles of the gene MAP-KINASE-PHOSPHATASE-1/MKP1. We further show that mutation of two components of the endoplasmic reticulum-associated protein degradation system can suppress a weak hae hsl2 mutant, suggesting that the weak hae hsl2 mutant receptor proteins undergo ER-associated protein degradation. We further perform a number of experiments to examine the impact of phosphorylation on the activity of HAE. These results provide a number of important mechanistic details to our understanding of floral abscission, and suggest many lines of inquiry for future research.

This paper reports the impact on admission to the University of Missouri-Kansas City's 6-yr. combined baccalaureate-doctor of medicine program of an innovation in selection procedures. In 1973 and 1974, the school's Council on Selection de-emphasized high school academic performance but continued to consider extensive biographical and interview data. Significant differences emerged in the correlations of various selection criteria with the Council's ratings of candidates in 1973 and 1974 in comparison with the prior year. Specifically, admission test score which had the highest correlation (.58) in 1972 was only .18 in 1973. The negative correlation (−.30) of race (discriminatory toward non-whites) in 1972 was not present in 1973 or 1974. Instead, the highest correlations were the interviewers' ratings and recommended decisions.

The purpose of this chapter is to describe the innovative Dissertation-in-Practice model being implemented in the University of Missouri Statewide Cooperative Doctoral Program in Educational Leadership (EdD Program). This doctoral program develops scholarly practitioners who are able to address critical problems of practice through the use of theory, inquiry, and practice-oriented knowledge. While these skills are utilized to create purposeful, professional products throughout the program, the redesigned Dissertation-in-Practice at MU is intended to further showcase the impact of the students' work as scholarly practitioners through dissemination-ready components. The chapter includes the history of the program and a description of the process through which program faculty redesigned the dissertation from a traditional five-chapter model to its current six section form. This restructuring, which includes dissemination to scholars and practitioners, is detailed. The chapter concludes with emerging supports for the scholarly practitioner graduates.

IntroductionApproximately 50% of individuals with fibromyalgia (a chronic widespread pain condition) have comorbid insomnia. Treatment for these comorbid cases typically target pain, but growing research supports direct interventions for insomnia (eg, cognitive behavioural treatment for insomnia (CBT-I)) in these patients. Previous research suggests sustained hyperarousal mediated by a neural central sensitisation mechanism may underlie insomnia and chronic pain symptoms in fibromyalgia. We hypothesise CBT-I will improve insomnia symptoms, improve clinical pain and reduce central sensitisation. The trial will be the first to evaluate the short-term and long-term neural mechanisms underlying insomnia and pain improvements in fibromyalgia. Knowledge obtained from this trial might allow us to develop new or modify current treatments to better target pain mechanisms, perhaps reversing chronic pain or preventing it.Methods and analysisFemale participants (n=130) 18 years of age and older with comorbid fibromyalgia (with pain severity of at least 50/100) and insomnia will be recruited from the University of Missouri in Columbia, Missouri, and surrounding areas. Participants will be randomised to 8 weeks (plus 4 bimonthly booster sessions) of CBT-I or a sleep hygiene control group (SH). Participants will be assessed at baseline, post-treatment, 6 and 12 months follow-ups. The following assessments will be completed: 2 weeks of daily diaries measuring sleep and pain, daily actigraphy, insomnia severity index, pain-related disability, single night of polysomnography recording, arousal (heart rate variability, cognitive affective arousal), structural and functional MRI to examine pain-related neural activity and plasticity and mood (depression, anxiety).Ethics and disseminationEthics approval was obtained in July 2018 from the University of Missouri. All data are expected to be collected by 2022. Full trial results are planned to be published by 2024. Secondary analyses of baseline data will be subsequently published.Trial registration numberNCT03744156.

The Impact

Under the direction of the United States Department of Energy (DOE) National Nuclear Security Administration (NNSA) Office of Material Management and Minimization (M3) Reactor Conversion Program, the University of Missouri Research Reactor (MURR®) plans to convert from highly enriched uranium (HEU) fuel to low-enriched uranium (LEU) fuel. Low power physics startup test predictions, transition core planning, and analysis for a proposed fission-based molybdenum-99 production upgrade were done in support of LEU fuel conversion. As a first step to LEU fuel conversion, low-power physics tests will be performed to calculate reactor physics parameters. These parameters include flux distributions, coefficients of reactivity, and critical assembly measurements. To facilitate this test, reactor physics calculations were performed using MCNP5 to predict the values of these parameters. Implications of these predictions and areas of uncertainty in the prediction analysis are also discussed. Once MURR completes the testing of the initial LEU core, MURR will enter into a series of transition cycles until steady-state mixed-burnup operation is reached. A Python program was developed that incorporated the constraints of MURR operation while minimizing the time MURR will have to operate atypically during the transition cycles. The impacts of the transition cycles on experiment performance are reported, as well as the number of fuel elements needed. Finally, preliminary analysis on a proposed molybdenum-99 production device at MURR was performed. This analysis shows the impact on the reactor power distribution with implications to predicted safety margins as a part of the larger scope of the experiment analysis.

This manuscript is a qualitative design, which studied diversity disparity in high education that relates to faculty and the student body. The setting dwells within the University of Missouri system, more specifically, this study concentrates on two campuses; the University of Missouri-Columbia and University of Missouri-Kansas City. The research identified the attributes of an effective change agent leader, policy and the impact it has on culture and organizational settings, and understandings of the importance of organizational value in relation to diversity and gender identification. The conceptual frameworks that guided this study were cultural competency, critical race theory, and transformational leadership (Cross, 1989; Gooden and Norman-Major; Northouse, 2013). The reoccurring research themes were: policy, leadership, and core organizational values. The conclusions suggested from this inquiry are transformational leaders should embrace and encourage differences and show empathy. Furthermore, a leader includes attributes of an actionable change agent. The data also supported the notion of inclusive policy and trust within the higher education system that creates organizational value.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Students continue to go to college to seek additional education and see that it will lead to a higher income throughout their life. Students often use student financial aid and work to pay for their education. Employers identify that students do not have the skills needed to succeed in the job market. This study found that non-tradition students and females have significantly more debt than traditional students and male students. The study also found that non-traditional students are less likely to participate in career building activities outside of the classroom. It also found that students are worried about their financial future, and they would like to participate in more career-building activities, but financial constraints can impact their ability to do so.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The purpose of this quantitative study was to analyze the impact of early access to algebra on developmental math enrollment in college. This study specifically analyzed 30 St. Louis area high schools. Developmental math enrollment numbers and the percentage of students with early access to algebra in the eighth grade were analyzed to address the research questions. A hierarchical multiple linear regression was used to find a statistically significant relationship between early access to Algebra 1 and developmental math enrollments in college. High schools with a higher percentage of students with early access to Algebra 1 had fewer graduating students requiring developmental mathematics courses in college.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation is composed of three essays examining inside debt. The first essay tests the impact of inside debt on security issuance decisions. I find that CEOs with high debt incentives are more likely to issue equity that debt, unlever firm capital structure, and hold debt of longer average maturity. The results indicate that managers with high debt incentives favor financing decisions that decrease firm risk. The second essay examines the determinants of use and magnitude of inside debt. I find a positive association between inside debt and CEO talent. In addition, I find that inside debt affects the likelihood of CEO post-retirement board service and CEO successor characteristics. The third essay examines the impact of inside debt on corporate dividend policy. I find that companies with large CEO holdings of inside debt are more likely to pay and increase dividends, and have larger dividend payouts. The results indicate that inside debt, by reducing firm risk, positively influences corporate dividend policy.
