Natural Selection On Mrna Secondary Structure And Its Correlation With Protein Functional Groups, Suresh Solaimuthu

Dissertations

Natural selection may occur at multiple levels of the biological hierarchy, including at the molecular level. It may occur on any phenotypic trait that evidences variation and that is heritable. This research uses computational methods to investigate whether the stability of the secondary structures of mRNAs has been the subject of natural selection.

The DNA sequence that codes for a particular target protein is only partially determined by that protein, since the redundancy of the genetic code permits multiple possible synonymous codons for each peptide. An RNA transcript of a DNA protein template (gene) folds back on itself through complementary …

Design Of Novel Drug Delivery System And Optimal Dosage Regimens, Kwang Seok Kim

Dissertations

Three representative drug delivery systems were analyzed to emphasize the roles of mathematical models and computer-aided simulations in pharmaceutical research. In the first project, a protocol was developed so that the optimal regimen, consisting of the intravenous boluses and subsequent infusion of theophylline, could be obtained once information on the pharmacokinetics became available. The method was based on a two-compartment model of the human body. A module was created and posted on a website for free access. The second project dealt with the transdermal heat-assisted delivery of corticosterone. Heat conduction and drug diffusion through the patch and the skin were …

Study Of Magnetic Helicity In Solar Active Regions And Its Relationship With Solar Eruptions, Sung-Hong Park

Dissertations

It is generally believed that eruptive phenomena in the solar atmosphere such as solar flares and coronal mass ejections (CMEs) occur in solar active regions with complex magnetic structures. The magnetic complexity is quantified in terms of twists, kinks, and interlinkages of magnetic field lines. Magnetic helicity has been recognized as a useful measure for these properties of a given magnetic field system. Magnetic helicity studies have been naturally directed to the energy buildup and instability leading to solar eruptions. However, in spite of many years of study, detailed aspects of initiation mechanisms of eruptive events are still not well …

A Numerical Study On The Propagation And Interaction Of Strongly Nonlinear Solitary Waves, Qiyi Zhou

Dissertations

We study numerically a strongly nonlinear long wave model for surface gravity waves propagating in both one and two horizontal dimensions. This model often referred to as the Su-Gardner or Green-Naghdi equations can be derived from the Euler equations under the assumption that the ratio between the characteristic wavelength and water depth is small, but no assumption on the wave amplitude is required. We first generalize the model to describe large amplitude one-dimensional solitary waves in the presence of background shear of constant vorticity. After computing the solitary wave solution of the strongly nonlinear model, the interaction between two solitary …

Computational Methods For Two-Phase Flow With Soluble Surfactant, Kuan Xu

Dissertations

A mathematical model is formulated and solved for the two-phase flow of a viscous drop or inviscid bubble in an immiscible, viscous surrounding fluid in the zero Reynold's number or Stokes flow limit. A surfactant that is present on the interface is also soluble in the exterior fluid, and the drop is deformed by an imposed linear flow. The geometry is two-dimensional and Cartesian.

The dissolved surfactant is considered in the physically realistic limit of large bulk Péclet number. That is, it convects and diffuses as a passive scalar in the bulk flow where the ratio of its convection to …

Atomic And Electronic Structure Studies Of Nano-Structured Systems : Carbon And Related Materials, Sumit Saxena

Dissertations

Modeling in the framework of density functional theory has been conducted on carbon nanotubes and graphene nano-structures. The results have been extended to non-carbon systems such as boron nanostructures. Computational studies are complemented by experimental methods to refine the structural models and obtain a better understanding of the electronic structure.

It is observed that the zigzag edged bilayered graphene nanoribbons are highly unstable as compared to their armchair counterparts. A novel approach has been proposed for the patterning of chirality/diameter controlled single walled carbon nanotubes. Nanotube formation is found to be assisted by edge ripples along with the intrinsic edge …

The Public Understanding Of Climate Change : A Case Study Of Taiwanese Youth, Shih-Yun Kuo

Dissertations

Global climate change is likely to be the most challenging environmental dilemma of the 21st century because its impacts on ecosystems and human society are transnational in scale and long term in scope. Due to its high scientific complexity and uncertainty and high political and economic sensitivity, mitigating the problem will require interdisciplinary cooperation and collective and sustained efforts on the part of all nations. Sufficient domestic support from both government and the lay public will not only be significant to the success of an international climate regime, but also crucial to the effectiveness of potential domestic climate policies.

The Perceptions Of Elite Male Gymnasts Of The Effects Of Punishment On Self-Efficacy And Athletic Performance, Jason David Selk

Dissertations

Existing literature suggests that coaches should use rewards rather than punishment for motivational purposes with athletes. The greatest argument against punishment lies in the evidence that the short-term positive effects on skill achievement are outweighed by the longterm negative effects on self-efficacy. Still, punishment is widely practiced within the coaching world; however, little research on coaching practices exists addressing the possibility that punishment could be utilized more effectively. As a beginning exploration of this topic, twelve elite male gymnasts were interviewed to determine what reinforcement their coaches used to motivate them. The results of the interviews seemed to reveal five …

The Evolution Of Self-Directedness In An Undergraduate Ethics Course: A Comparison Of Three Course Delivery Methods, Shawna Leigh Strickland

Dissertations

Many studies have investigated relationships between self-directedness and various indicators of success in university coursework but few have explored the evolution of self-directedness that may or may not occur in these settings. This study sought to discover how self-direction in learning of participants in an undergraduate healthcare ethics course evolved. Emphasis of this evolution was placed on the learner’s perspective. The study also examined the relationship between course delivery method and degree of evolution of self-directedness during the studied semester. A traditional section, a blended section, and an online section of the healthcare ethics course were studied. Within three sections …

Coping And Assumptive World Views: Comparing Parents Of Murdered Children And Parents Of Missing/Returned Children In The Management Of Their Grief, Miriam Joy Anderson

Dissertations

This study investigates the relationship between psychological coping, religious coping, and assumptive world views of parents of murdered children and parents of missing/returned children. The latter group refers to parents who had a missing child who was returned prior to participating in the study. A sample of 82 parents of murdered children and 14 parents of missing/returned children completed a series of self-report measures assessing grief, coping, and assumptive world views. Due to statistical power limitations in the missing/returned group, proposed hypotheses were examined using only data from parents of murdered children. The hypothesis that longer time since the event …

Emotional Response Patterns And Emotional Numbing In Adult Female Victims Of Sexual Assault With Ptsd, Tristan A. Robinson

Dissertations

DSM symptoms of emotional numbing appear to have a major impact on the course and outcome of posttraumatic stress disorder (PTSD), yet the construct definition of emotional numbing itself has not been clearly established. Two opposing conceptualizations of this construct have been proposed in the traumatic stress literature. One holds numbing to be a form of non-effortful emotional avoidance, akin to dissociation, that results in diminished responsiveness to emotional stimuli in general (Foa, Zinbarg, & Rothbaum, 1992; Foa & Hearst-Ikeda, 1996). The other suggests that numbing entails a deficit in responsiveness to positive emotional stimuli but not to negative emotional …

Consistency Of Written Trauma Narratives Over A Course Of Trauma-Focused Therapy, Juliette Marissa Mott

Dissertations

Several of the procedures commonly used in trauma-focused therapies are similar to techniques that have been shown to influence the consistency and accuracy of memory in experimental settings. These techniques include verbalizing a non-verbal memory, repeatedly recalling an event, and recalling an event in the presence of another person. In an effort to examine the impact of such techniques on memory for a traumatic event, and in turn the impact of traumatic memory change on treatment outcome, the present study examined changes in written trauma narratives created over the course of trauma-focused therapy. Participants were PTSD-positive female survivors of interpersonal …

Comparing Perceptions Of Campus Crime Severity Among Community College And Public Four-Year University Students, Loren Morell Lundstrom

Dissertations

In recent years violent crimes on several university campuses have been highlighted by mass media, drawing national attention to the issue of campus crime. Not all college campuses, however, experience the same level of crime. While community colleges serve roughly half of all undergraduates in the U.S., statistically these public institutions account for a much lower percentage of violent crimes than their public four-year university counterparts. With the thought that perceptions and beliefs govern one’s behavior, this study considers the possibility that elements of institutional culture influence student perceptions about campus crime. Two hundred and sixty-five (265) college students, from …

Pregnant Job Applicants And Employment Interviews: The Consequences Of Stigmatization And Absenteeism And An Examination Of Strategies To Overcome Them

Dissertations

Discrimination against pregnant applicants may be partially explained by concerns about a pregnant employee missing work and possibly quitting (Cunningham & Macan, 2007). The purpose of the first study is to explore further the notion that pregnant applicants receive less favorable reactions during the selection process due in large part to concerns regarding potential absenteeism. This study explores whether applicants who need an equivalent amount of time off, but for different reasons, are perceived and rated similarly as a pregnant applicant. The results showed that all applicants requesting time off, regardless of reason, received less favorable hiring ratings compared to …

Defining The Balance-Supportive Supervisor: The Antecedents, Actions, And Outcomes Of Supervisor Support For Employee Work-Nonwork Balance, Jessalyn L. Arnold

Dissertations

Work-nonwork conflict remains a crucial concern for both employees struggling to balance work and non-work roles (Bond, Thompson, Galinsky, & Prottas, 2002) and companies seeking to enhance their ability to attract, retain, and leverage talent (De Janasz & Behson, 2007; Towers & Perrin, 2006). Research has demonstrated that factors such as supervisor support for work-nonwork balance can reduce employees’ experience of work-nonwork conflict. Few studies, however, have investigated the individual characteristics of supervisors who are most likely to provide work-nonwork support. This study extends previous research by investigating the relationships between supervisors’ identity salience, work-nonwork support attitudes, and perceptions of …

Influence Of Financial And Policy Environments On The Business Strategy Of Biotechnology Companies In India, Sumesh Mohan Arora

Dissertations

The biotechnology industry thrives on innovation and new knowledge creation, but is also capital intensive with a complex regulatory environment (Hine and Kapeleris 2007). It is seen as a sunrise industry by the Indian government (Natesh and Bhan 2009). Current literature on the business strategy of Indian biotechnology companies and the influence from external factors is very limited. The objective of this research was to qualitatively test the applicability of the Miles and Snow (1978) theory of organizational behavior which describes four strategy choices: prospector, analyzer, defender and reactor, in the context of the Indian biotechnology sector. Research on Western …

The Taifa Of Denia And The Medieval Mediterranean, Travis Bruce

Dissertations

This dissertation treats the Muslim kingdom of Denia on the Spanish Mediterranean coast. Through a singular political program, the eleventh-century rulers of Denia created a maritime kingdom based on the resources and networks of the Mediterranean. Denia played a unique role as a Mediterranean polity, developing economic links with Christian Barcelona, Sardinia, Pisa and Genoa that would connect Muslim and Christian populations over several centuries. The dissertation demonstrates the importance of economics in the Muslim-Christian relations of the western Mediterranean using Latin archival documents, Latin and Arabic narrative sources, and archaeological and numismatic evidence. It explores the extent to which …

Exploring The Use Of Video-Teleconferencing For On-Duty Training In The St. Charles Fire Department And St. Louis Metropolitan Emergency Response Community, Robb F. Watkins

Dissertations

This study was conducted because the St. Charles Fire Department needed to identify a way to change its training delivery system to accommodate training in quarters for on-duty companies. St. Charles was experiencing: budget reductions, staffing shortages, delayed responses due to training, and increasing response times. The department identified video teleconferencing (VTC) as a possible solution to their training delivery dilemma. This study was a qualitative study including surveys and interviews that evaluated the VTC implementation process. The research question was, “How can fire department training be constructed to enhance the frequency and adequacy of training and reduce the need …

Urban Middle School Teachers: Tenured Versus Non-Tenured Teachers And The Impact They Have On Academic Achievement, Rochelle Harris-Clark

Dissertations

The Iowa Test of Basic Skills (ITBS) is used in the district of Study School No. 1 to give insight on student academic skill level in terms of years and months. Teacher strategies and expertise in the area of education is an integral part of the educational process. Tenure status, or the years of experience, is plagued with the idea that it promotes or has an impact on student achievement. Although there were a significant number of tenured special education and general education teachers at the study school during the 2005–2006, 2006–2007, and 2007–2008 school years, the school did not …

When viewed through the lens of global warming, or the increase of greenhouse gases through the increase in the temperature of the …

An Automated Framework For Defect Detection In Concrete Bridge Decks Using Fractals And Independent Component Analysis, Fadi Abu-Amara

Dissertations

Bridge decks deteriorate over time as a result of deicing salts, freezing-andthawing, and heavy use, resulting in internal defects. According to a 2006 study by the American Society of Civil Engineers, 29% of bridges in the United States are considered structurally deficient or functionally obsolete. Ground penetrating radar (GPR) is a promising non-destructive evaluation technique for assessing subsurface conditions of bridge decks. However, the analysis of GPR scans is typically done manually, where the accuracy of the detection process depends on the technician's trained eye. In this work, a framework is developed to automate the detection, localization, and characterization of …

Parent Engagement And Cultural Capital: Negotiating Culture In A Multilingual/Multiethnic School, Paula Andrea Echeverri-Sucerquia

Dissertations

This study explored how a multicultural/multilingual school negotiated culture with limited English proficient (LEP) students' families, particularly in the context of parent involvement activities. In order to understand how such negotiation of culture occurred, the researcher focused on the perspectives that school administrators, teachers and parents of students in an English as a Second Language (ESL) program had on the education of LEP students and their parents' involvement in school-organized activities. It also focused on the participants' understandings of cultural capital and the extent to which the school builds on immigrant /sojourner families' knowledge and culture to support their children's …

Physician's Experiences With Death And Dying: A Phenomenological Study, Deborah Jo Corker

Dissertations

This qualitative phenomenological study attempts to gain the physician's essences, meanings and understanding surrounding death and dying. Starting with themes revealed in literature, in-depth interviews were used to ask selected physicians providing care: How does death affect them? Are physicians receiving adequate training in end-of-life care? Does the medical culture still see death as failure? How do they find meaning in end-of-life care? Using three different groups of physicians: early in career, mid-career, and retired, this research attempted to examine the phenomena of death and dying over apparent time and developmental experiences of physicians. Results: Physicians have not been adequately …

Individual-Based Modeling Of White-Tailed Deer (Odocoileus Virginianus) Movements And Epizootiology, Lene Jung Kjaer

Dissertations

White-tailed deer (Odocoileus virginianus) are important game mammals and potential reservoirs of diseases of domestic livestock, so diseases of deer are of great concern to wildlife managers. In many situations, models can be useful for integrating existing data, understanding disease transmission patterns, and predicting effects on host populations. Individual-based modeling (IBM) has become more commonplace in ecology as a tool to link individual behavior to population dynamics and community interactions, especially for gauging the effects of management actions. Spatially explicit IBMs are especially useful when ecological processes, such as disease transmission, are affected by the spatial composition of the environment. …

Political Ideology And Its Relationship To Perceptions Of Social Justice Advocacy Among Members Of The American Counseling Association (Aca), Janeé Steele Steele

Dissertations

Social justice has become an increasingly controversial topic among members of the American Counseling Association (ACA). Specifically, concerns have been raised over what is perceived to be: (a) the liberal political agenda of social justice advocates, (b) the marginalization of conservative counselors, and (c) the inappropriate use of ACA resources for social activism. Concerns of this nature suggest that contrary to what is most often expressed by social justice proponents, many counselors may question if efforts to address social and political issues are appropriate tasks for counselors in their professional roles. They further imply that opinions about social justice advocacy …
