The Transcriptome Response Of The White-Rot Fungus Phanerochaete Chrysosporium To Maple And Miscanthus, Mashael Rashed Alaradi

Masters Theses

Lignocellulosic biomass is a valuable feedstock for the production of liquid biofuels. However, liquid biofuel production from lignocellulose is economically challenging due to the difficulties associated with separating the cellulosic sugars from lignin. In addition, the current thermochemical methods to deconstruct lignocellulose typically involve hazardous chemicals that can negatively impact the environment. Recent studies have demonstrated the efficacy of white-rot fungi as alternative pretreatment agents that can lower the costs of lignocellulose deconstruction and reduce negative impacts on the environment. However, understanding of the biochemical mechanisms of lignocellulose breakdown used by these fungi is limited, particularly with respect to the …

Utilizing Incentives To Increase Teacher Praise, Kari L. Meyer

Masters Theses

An ABA single-subject research design was used in examining the effect on school staff's written praise and student behavior when staff were provided with an incentive (i.e., would an incentive raffle increase written praise and appropriate student behavior?). Participants included 93 staff members and 755 students at an elementary school in central Illinois. School staff members were instructed on the importance of using praise, and praise notes were measured on a weekly basis by praise type (behavior-specific or general), staff member type (core teacher, non-core teacher, or non-teacher), and student type (at-risk or non-at-risk). Results indicated that the faculty incentive …

Behavior Of Different Sizes Of Strontium Titanate Substrates In Electrochemical Modifications, Shuxin Luo

Masters Theses

In our previous atomic force microscopy (AFM) studies of 5 mm x 5 mm single crystal SrTiO₃ (STO(100)) substrates, rutile TiO₂ crystals were found on the substrates surfaces after electrochemical modification. These crystals were found mainly in the area of contact between the substrate and the gold-coated alligator clip that was not supposed to be immersed into the electrolyte and that served as a connection between the STO working electrode and the potentiostat circuit. The size and density of the crystals were found to depend on electrochemical potential, its polarity, the length of modifying time, and the total …

"A Babe In The Woods?": Billy Graham, Anticommunism, And Vietnam, Daniel Alexander Hays

Masters Theses

This thesis focuses on famous evangelist Billy Graham's role in the Vietnam War, both as a public supporter and private advisor. It argues that, contrary to his self-depiction, he was no "babe in the woods," no mere neophyte or bystander. Rather, America's most famous preacher was an active participant in promoting and even planning the war. Graham's evangelical theology, with his premillennialist beliefs, led to his intensely anticommunist worldview, where communism was the Antichrist. His public support buttressed the presidents prior to and during the Vietnam War and, sometimes, Graham even delved into policy recommendations for the war.

Graham's role …

I Could Have Been You: Core-Self Differentiation As It Relates To Empathy And Aggression, Nazmi Cem Turker

Masters Theses

Previous research showed that the more one feels similar to a specific other, the less aggressive and the more empathic one behaves toward the other. Some people might have a self-concept that makes them prone to feel similar to others in general. Those people, despite being aware of the differences between them and others, may feel that their differences do not make them inherently or essentially different from others -they may feel their core-self is similar to others despite outer differences, while some may not feel as much so. This tendency was conceptualized as a trait related to one's self-concept …

The Bystander Intervention In Bullying Survey: An Examination In An Elementary School Sample, Kirsten Taylor

Masters Theses

Researchers and school administrators have recognized the importance of peer bystanders in bullying situations, but there are very few studies that examine this phenomenon within Latané and Darley's (1970) bystander intervention model. The five sequential steps in this model include: notice the event, interpret the event as an emergency that requires assistance, accept responsibility for intervening, know how to intervene or provide help, and implement intervention. Nickerson, Aloe, Livingston, and Feeley (2014) created the Bystander Intervention in Bullying Survey based on Latané and Darley's model. Nickerson and colleagues and Jenkins and Nickerson (in press) have found evidence of reliability and …

Teacher Characteristics And Influence With The Bystander Intervention Model, Morgan A. Eldridge

Masters Theses

Bullying, both traditional and cyber, have been associated with several negative outcomes for students, and teachers have been identified as potential targets for prevention and intervention of bullying occurrences. The importance of bystanders has been recognized; however, there are few studies that examine personal characteristics that relate to the five bystander behaviors within the Bystander Intervention Model (notice the event, interpret as an emergency, accept responsibility, know what to do, and act). This study examined personal characteristics (e.g., affective empathy and perceived level of bullying seriousness) and their relation to each of the five steps of the Bystander Intervention Model …

An Examination Into The Instruction Of The Alphabet During Preschool Years, Amanda Titus

Masters Theses

Instruction of the letters of the alphabet is a controversial topic among early childhood educators. Not only is it debated whether letter instruction is developmentally appropriate but there is then the discussion concerning how the letters are best taught once a program deems it is developmentally appropriate. In this study, 87 children were assessed at two separate times during the school year to determine a method of instruction that proved most effective. The study took place over three consecutive school years. The first year, 27 students were exposed to alphabetic instruction through a combination of music and mnemonic device assisted …

Export-Oriented Entrepreneurship Intensity And Economic Growth In Developing And Developed Countries, Xueting Sun

Masters Theses

This paper analyzes the impact of export-oriented entrepreneurship intensity on national economic growth using data for 64 countries over the 2006-2013 period. We draw on entrepreneurship, entrepreneurship and economic growth, export-oriented entrepreneurship and economic growth, and export intensity of entrepreneurship and economic growth theories to affirm that export-oriented entrepreneurship and export-oriented entrepreneurship intensity is profound for the national economic growth of countries.

The findings suggest that greater total entrepreneurial activity (TEA) is associated with a higher rate of economic growth in developed countries but not in developing countries. Also, greater export-oriented entrepreneurial activity (EEA) is associated with a higher rate …

A Study Of Acoustic Reflections To Determine The Location, Size, Shape, And Orientation Of Reflecting Objects, Brandon M. Heller

Masters Theses

This study was conducted to examine the properties of sound in relation to echolocation, specifically in relation to its use by humans. Through my thesis, objects of varying shape and size were subjected to a sound wave to determine details about the object from the reflected sound. The shapes' comparisons were conducted at varying distances, measuring the intensity of the returning sound wave at several frequencies. The results demonstrated a correlation between the intensity of the sound in regards to distances, area of the reflector, and the shape of the reflector.

On Solid Ground I Stand: Narratives On Disclosure, Resilience, And Faith Amidst Recognition Of Childhood Sexual Abuse, Wade Rhodes Dundee

Masters Theses

Childhood sexual abuse seems to be a hidden secret in American society; one of the famous, "If we don't talk about it, it won't happen" narratives. However, we know this is not true. Both the National Sexual Violence Resource Center (2012) and Center for Disease Control and Prevention (2005) state one in four girls and one in six boys will fall victim to sexual abuse before they celebrate their 18th birthday. There is a high probability that because of the alarming lack of disclosure of male survivors, these statistics could be incorrect and could hinder creating or allowing for conversations …

Structural Change And Productivity Growth In Developing Countries, Ahmed Salim Nuhu

Masters Theses

The dual-economy model predicts that holding productivity constant, labor reallocation from less to more productive sectors, also known as 'structural change' results in improvement in economy-wide productivity. The objective of this thesis is to test the empirical predictions of this model using sectoral-level data from twenty-eight developing countries. Using the shift-share growth decomposition approach, we find regional growth-enhancing effects of structural change in Asia, Latin America and North Africa from, 1980 to 2000 and growth-reducing effects in Sub-Saharan Africa over the same period. However, as intersectoral productivity gaps disappeared after 2000, technological progress led the growth process in much of …

Detection Of Antibiotic Resistance Loci In Wastewater And Fresh Water Samples, Mohammed Hamed Almalki

Masters Theses

Proper treatment of municipal wastewater is important not only for prevention of eutrophication but also for public health concerns. One consideration for wastewater treatment is the presence of organisms carrying antibiotic resistance genes. If these organisms survive the wastewater treatment process and are released into the streams, they can pose significant risks to public health. In addition, their presence also raises concerns for lateral gene transfer events at the wastewater plant. The spread of antibiotic loci has a major impact in public health and clinical therapy because resistant organisms render conventional treatments of important illnesses difficult. Beta-lactam drugs are known …
