Syntheses And Characterization Of Bis(Amino)Cyclodiphosphazane Complexes Of Group 4- And -15 Elements, Mathew Etang Otang

Theses and Dissertations

In the first part of this work, the interaction of sodium tert-butoxide and sulfur with Group 4 metal bis(tert-butylamido)cyclodiphosph(III)azanes dichlorides, {[tBuNP)2tBuN)2]MCl2}, where M is Zr or Hf, is reported. The reaction of two equivalents of NaOtBu with {[tBuNP)2tBuN)2]MCl2}, M = Zr, Hf, resulted in the isolation of the first metal alkoxide complexes {[tBuNP)2tBuN)2]M(OtBu)2}, 35 (M =Zr) and 36 (M = Hf) of cyclodiphosphazanes. The oxidation of compounds 35 and 36 with elemental sulfur yielded {[tBuNP=S)2tBuN)2]M(OtBu)2}, 37 (M = Zr) and 38 (M = Hf), respectively. Similarly, the oxidation of {[tBuNP)2tBuN)2]MCl2}, M = Zr, Hf, with elemental sulfur led to the …

Characterization Of Kraft Alkali Lignin And Products Of Its Thermal Degradation By Fractional Pyrolysis Methods, Keith Michael Voeller

Theses and Dissertations

At present, methods addressing the characterization of lignin and its decomposition products are limited. Typical approaches reported various spectroscopic, chromatographic and thermal methods. None of the methods is ideal for different reasons. In this study, a novel thermal carbon analysis (TCA) was developed providing essential mass balance data complementary to liquid-liquid extraction (LLE) prior to separation and identification by gas chromatography and mass spectrometry (GC-MS) as well as thermal desorption-pyrolysis-gas chromatography-mass spectrometry (TD-Py-GC-MS) to fully characterize lignin and its degradation products from hydrothermal treatment in subcritical water conditions.

The TCA method enabled a quantitative thermal evolution profile through TD and …

Shaking In Their Digital Boots: Anxiety And Competence In The Online Basic Public Speaking Course, Joshua N. Westwick, Karla M. Hunter, Laurie L. Haleta

Basic Communication Course Annual

In response to a call for increased research on educational quality of online public speaking courses, this study assessed online course impacts on students’ (N = 147) speaker anxiety and self-perceived communication competence. A significant decrease in speaking anxiety occurred over the course of the semester, supporting efficacy of the online basic speech course at the university level. However, the predicted significant increase in self-perceived communication competence was not found, warranting additional considerations in online course designs. The significant reduction in speaking anxiety within the online course is promising and suggests that this learning goal can be met in this …

[Introduction To] Posthumanism And Educational Research, Nathan Snaza, John A. Weaver

Bookshelf

Focusing on the interdependence between human, animal, and machine, posthumanism redefines the meaning of the human being previously assumed in knowledge production. This movement challenges some of the most foundational concepts in educational theory and has implications within educational research, curriculum design and pedagogical interactions. In this volume, a group of international contributors use posthumanist theory to present new modes of institutional collaboration and pedagogical practice. They position posthumanism as a comprehensive theoretical project with connections to philosophy, animal studies, environmentalism, feminism, biology, queer theory and cognition. Researchers and scholars in curriculum studies and philosophy of education will benefit from …

[Introduction To] The Other Rise Of The Novel In Eighteenth- Century French Fiction, Olivier M. Delers

Bookshelf

The rise of the novel paradigm—and the underlying homology between the rise of a bourgeois middle class and the coming of age of a new literary genre—continues to influence the way we analyze economic discourse in the eighteenth-century French novel. Characters are often seen as portraying bourgeois values, even when historiographical evidence points to the virtual absence of a self-conscious and coherent bourgeoisie in France in the early modern period. Likewise, the fact that the nobility was a dynamic and diverse group whose members had learned to think in individualistic and meritocratic terms as a result of courtly politics is …

Effect Of Post-Weaning Management And Age At Weaning On Calf Growing And Finishing Performance, Jason M. Warner, Curtis J. Bittner, Karla H. Jenkins Jenkins, Rick J. Rasby, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

The impact of post-weaning management system and calf age at weaning on growing and finishing performance was evaluated. During the growing phase, cattle in the fast-track system had improved intake, gain, and feed conversion. Although initial finishing weight was similar between systems, slow-track cattle had greater intake, gain, final body weight, and carcass weight. While the impact of age at weaning was negligible, the improvement in finishing performance for slow-track cattle demonstrates the value of different management systems.

Statistics Used In The Nebraska Beef Report And Their Purpose

Nebraska Beef Cattle Reports

The purpose of beef cattle and beef product research at University of Nebraska–Lincoln is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc.) of beef production. Obviously, the researcher cannot apply treatments to every member of a population; therefore, he/she must sample the population. The use of statistics allows the researcher and readers of the Nebraska Beef Report the opportunity to evaluate separation of random (chance) occurrences and real biological effects of a treatment. Following is a brief description of the majorstatistics used in the beef report. For a more detailed description …

Estimation Of British- And Continental-Specific Heterosis Effects For Birth, Weaning, And Yearling Weight In Cattle, Lauren N. Schiermiester, R. Mark Thallman, Larry A. Kuehn Kuehn, Matthew L. Spangler

Nebraska Beef Cattle Reports

Heterosis, assumed proportional to expected breed heterozygosity, was calculated for 6,834 individuals with birth, weaning, and yearling weight records from Cycle VII of the U.S. Meat Animal Research Center Germplasm Evaluation Program. Heterosis was further estimated by proportions of British x British (BxB), British x Continental (BxC), and Continental x Continental (CxC) crosses. Estimates of BxB, BxC, and CxC heterosis were significant for weaning and yearling weight. This study illustrated that differences among biological types exist and provide an opportunity to utilize specific breeds and exploit heterosis in a crossbreeding system to achieve production goals.

Competition Expressed: Marking Places Within Rural And Urban Landscapes, Ralph J. Hartley, Sharon L. Kennedy

Department of Anthropology: Faculty Publications

The extent to which marking places with images, symbols and/or script on a landscape reflect the dynamics of a socio-economic environment continues to be a subject of interest in social science. Places become socio-culturally meaningful often because of the content of the markings on non-portable surfaces. In some contexts the information content of the markings reveal a perception of propriety when competition for space or other resources between groups and non-kin related individuals characterizes a social environment. In other contexts the content of markings reflect competition between individuals for resources, status, or prestige. Urban environments, dense with diverse human activities, …

Model And Sensor-Based Recommendation Approaches For In-Season Nitrogen Management In Corn, L. J. Thompson, R. B. Ferguson, N. Kitchen, D. W. Frazen, M. Mamo, H. Yang, J. S. Schepers

Department of Agronomy and Horticulture: Faculty Publications

Nitrogen management for corn (Zea mays L.) may be improved by applying a portion of N in-season. This investigation was conducted to evaluate crop modeling (Maize-N) and active crop canopy sensing approaches for recommending in-season N fertilizer rates. These approaches were evaluated during 2012–2013 on 11 field sites, in Missouri, Nebraska, and North Dakota. Nitrogen management also included a no-N treatment (check) and a non-limiting N reference (all at planting). Nitrogen management treatments were assessed for two hybrids and at low and high seeding rates, arranged in a randomized complete block design. In 9 of 11 site-years, the sensor-based …

A Pilot Study Investigating The Reasons For Playing Through Pain And Injury: Emerging Themes In Men’S And Women’S Collegiate Rugby, Leilani Madrigal, Jamie Robbins, Diane L. Gill, Katherine Wurst

Athletic Performance Research

Collegiate rugby is a competitive, collision sport, yet insufficient empirical evidence exists regarding participants’ perspectives on pain and injury. This study addressed male and female rugby players’ experiences with injury, and their views about playing through pain and injury. Eleven rugby players (five male; six female) competing in USA Rugby’s National College 7’s tournament participated in semi structured interviews, which were recorded, transcribed, and content-analyzed. Two major themes emerged: passion for sport and sport ethic. Passion for sport was composed of (a) love of the sport, (b) meaning of the sport, and (c) desire to be on the field. Sport …

Outcomes Associated With Blood Component Transfusion In Adult Trauma Patients, Allison R. Jones

Theses and Dissertations--Nursing

The purpose of this dissertation was to evaluate outcomes associated with blood component (BC) transfusion in adult trauma patients. Specific aims were to: 1) explore the relationship between traumatic injury, hemorrhage, and BC transfusion, focusing on consequences of the component storage lesion through presentation of a conceptual model; 2) systematically review research literature comparing outcomes of massively transfused major trauma patients based on ratios of BCs received; 3) evaluating the relationship between type of blood transfusion trauma patients received (whole blood versus BCs) and mortality likelihood after controlling for demographic and clinical variables; 4) evaluating the relationship between volume and …

An Nmr-Guided Approach To The Isolation Of Secondary Metabolites From Nrps And Pks Gene Clusters, Connor Craig

Honors Theses

Secondary metabolites continue to offer a promising source of novel chemical entities with therapeutic bioactivities. Our research aims to isolate secondary metabolites produced by non-ribosomal peptide synthetase (NRPS) and polyketide synthase (PKS) constructs. A metagenomic library was created from the marine bacterium Pseudoalteromonas sp., which was isolated from the Chesapeake Bay sponge Halichondria bowerbanki. Using a functional screen for PPTase activity we were able to identify colonies that contained NRPS and PKS gene clusters. Cultures of this microbe have been produced and analyzed using a combination of chromatography and 1H, 13C, HMBC, HSQC, COSY, AND NOESY NMR spectra. …

From Prisons To Asylums, And Back : Mental Health Policy In The Age Of Neoliberalism, Michele Martin

Honors Theses

This thesis seeks to explain why rates of severe mental illness in the criminal justice system have risen steadily throughout the past three decades, despite an increasing acknowledgement of the importance of mental health to overall health. Legislative, scientific, and societal advances have aimed at increasing access to and bolstering the quality of mental health care. Yet, the large numbers of severely mentally ill persons residing in the criminal justice system imply care in the community is not adequately serving their needs, or that, for whatever reason, they are not seeking care. I begin my analysis by considering mental health …

A Longitudinal Study Of Cis Students, Course Performance And Mbti Personality Types, Patricia Sendall, Alan Peslak, Wendy Ceccucci, S.E. Kruck

Management Faculty Publications

This research is a longitudinal study of Jungian personality traits and academic success of students enrolled in Computer Information Systems (CIS) courses. The Myers-Briggs Type Indicator (MBTI) measurement scale was self-analyzed by students in CIS courses from fall 2001 through spring 2013. The results of this study indicate that both Extroverts and Judgers have increased as percentage of enrollment between 2001-2003 and 2012-2013. There was no change in academic success, as measured by grades achieved, by personality type from 2001-2003 and 2012-2013.

An Incomplete Pass: Inadequacies In Ohio's Youth Concussion Legislation And The Ongoing Risk For Players, Andrew J. Kane

Journal of Law and Health

Broadly, this paper questions whether Ohio’s recently enacted youth concussion legislation adequately addresses the public health issue of sport-related brain injury, and contends that it does not. To that end, it first addresses the significance of traumatic brain injuries, including concussions, explaining that the failure to protect youth athletes from these potentially fatal conditions has largely resulted from a lack of awareness of their influence on neurological functions, and of their potential to cause serious brain injury. Next, this paper examines several legislative responses enacted by other states, all of which were in place before Ohio’s, and compares the recently …

Employment, Unemployment, And Underemployment In Africa, Stephen S. Golub, Faraz Hayat , '14

Economics Faculty Works

This chapter documents and analyzes the predominance of informal employment in Africa and shows that lack of demand for labor rather than worker characteristics is the main reason for pervasive underemployment. Integration into the global economy and exports of labor-intensive products are vital to boosting the demand for labor in Africa. Africa has some potential to become competitive in light manufacturing, but the most promising avenue for export-led growth of employment in many African countries is agriculture, including traditional cash crops such as cotton, coffee, cocoa, and groundnuts. Traditional cash crops, which are the source of livelihood for millions of …

Living In An (Im)Material World: Consuming Exhausted Narratives In New Grub Street, Emma C. Eisenberg

Honors Papers

Journalists often write about the death of various print and media forms—deaths that have yet to occur, but which we continually anticipate in deference to a tacit law which discards the past as a “useless encumbrance” of outmoded styles of consumption. But is that encumbrance necessarily useless? In this paper, I argue that George Gissing’s New Grub Street (1891), which narrates the deaths of two realist novelists and has been called an “epitaph for Victorian fiction,” lives out its own virtual death to good purpose. I discuss how Gissing uses the realist novel’s transitional or partially exhausted state to conserve …

Chaos And Learning In Discrete-Time Neural Networks, Jess M. Banks

Honors Papers

We study a family of discrete-time recurrent neural network models in which the synaptic connectivity changes slowly with respect to the neuronal dynamics. The fast (neuronal) dynamics of these models display a wealth of behaviors ranging from simple convergence and oscillation to chaos, and the addition of slow (synaptic) dynamics which mimic the biological mechanisms of learning and memory induces complex multiscale dynamics which render rigorous analysis quite difficult. Nevertheless, we prove a general result on the interplay of these two dynamical timescales, demarcating a regime of parameter space within which a gradual dampening of chaotic neuronal behavior is induced …

Rethinking The Ill Body In Phallocentric Western Culture: A Critical Engagement With Luce Irigaray, Sarah E. Kahn

Honors Papers

This capstone critically engages with the work of prolific, contemporary continental philosopher Luce Irigaray on subjectivity and the body in order to challenge widely held notions of the ill body in phallocentric culture. Within my project, phallocentrism means the privileging of an erect, rational, individually autonomous body with defined boundaries. Using sociologist Ken Plummer's journal during his liver disease, I extend Irigaray's critique of phallocentrism to the experience of illness in Western culture. Ill bodies occupy a space analogous to that of female bodies within Irigaray's theory, because phallocentrism subordinates ill bodies to the normative phallic body that is functional, …

Ultracrepidarianism In Forensic Science: The Hair Evidence Debacle, David H. Kaye

Faculty Scholarship

For over 130 years, scientific sleuths have been inspecting hairs under microscopes. Late in 2012, the FBI, the Innocence Project, and the National Association of Criminal Defense Lawyers joined forces to review thousands of microscopic hair comparisons performed by FBI examiners over several of those decades. The results have been astounding. Based on the first few hundred cases in which hairs were said to match, it appears that examiners “exceeded the limits of science” in over 90% of their reports or testimony. The disclosure of this statistic has led to charges that the FBI “faked an entire field of forensic …

Preface, Richard Thomas Eldridge

Philosophy Faculty Works

Art and its Objects ends abruptly with the claim – surprising in an age obsessed with distinguishing between facts and values and with worrying about the logical status of value judgments – that, deliberately, next to nothing has been said in this book about the evaluation of art. Instead, Wollheim's central aim is to understand what we are doing when we are either making or attending to art – an enterprise, as it were, of descriptive phenomenology. Two related, central ideas running through his account are that we demand a certain sort of experience from the things that we undertake …

Pillars And Buttes: A Petrologic Comparison Of Modern And Ancient Hydrocarbon Seep Rock, Erica C. Morelli

Honors Papers

Purpose: Literature on the formation of authigenic rock at cold seeps focuses on the role of microbes in creating geochemically favorable environment for the precipitation of carbonate and barite minerals. Less understood is the pathway that lithified microbial patches of seafloor sediment follow to become rock formations that are identified in strata dating back to the Silurian. In this study I will compare Holocene seep rock from the Gulf of Mexico to Cretaceous carbonates that have been identified as seep rock. Through the study of rock in its early stages of formation to rock that has likely undergone multiple phases …

Science And Medicine In Liudmila Ulitskaia’S Kazus Kukotskogo, William D. Wise

Honors Papers

Science and medicine play a fundamental role in Liudmila Ulitskaia's 2001 novel Kazus Kukotskogo. This paper argues that Ulitskaia employs science and medicine as a concrete means of considering such diverse questions as social life, morality, and religion in the work.

Reconstructing Seville: Translating Eduardo Del Campo’S Capital Sur, Hannah Lynn Varadi

Honors Papers

In the semi-biographical Capital Sur (2011), Spanish journalist Eduardo del Campo draws on experimental narrative techniques to portray his home city of Seville as he saw it in the 1990’s: a barometer of Spain’s social and economic crises. Here I compare modern translation theories to my own partial translation of this novel into English, which I place in the context of the U.S. translation publishing industry. I also show how the historical and cultural context of Seville influence the text’s themes—including del Campo’s critique of the hegemonic ways that countries such as the United States tend to exoticize Spain’s culture.

An Examination Of Factors That Contribute To Binge Eating Among Bariatric Patients, Erin Neuman-Boone

Electronic Theses and Dissertations

Binge eating is the most common eating disorder among individuals presenting for bariatric surgery. The majority of patients with pre-surgical binge eating experience a short-term reduction in binge eating symptoms following surgery. However, binge eating symptoms can re-emerge. This quantitative study examined variables related to and predictive of binge eating within the bariatric patient population. Specifically, the purpose of this study was to determine whether daily hassles, uplifts, depression, pre-surgical binge eating, time since surgery, and weight regain were predictors of binge eating within the bariatric patient population. One hundred and twenty-six participants completed either an electronic or paper version …
