Interest Group Scorecards And Legislative Satisfaction: Using Ratings To Explore The Private Bias In Public Policy, Daniel E. Chand

Graduate Theses and Dissertations

Despite their importance to our system, the study of interest groups has produced few concrete findings compared to other actors such as administrative agencies and political parties in the policymaking process. The absence of generalizable findings is partly explained by the unpopularity of the topic, but is primarily due to a deficiency of easily accessible data and lack of agreement over how to operationalize important concepts. In the following dissertation, I employ interest group "scorecards" (ratings of members of Congress) as an approach to examining interest groups in a generalizable manner. Specifically, I use scorecards to test the pluralist assumptions …

Algae To Propellants: Biosynthesis Of 1,2-Propanediol From Algal Derived Sugars, Lauren Rachelle Merriman

Graduate Theses and Dissertations

Propylene glycol dinitrate (PGDN) is an important component used in the formulation of energetic materials. A renewable, environmentally-friendly and effective production technique for the production of 1,2-propanediol, an important precursor to PGDN, is desired. While fermentation of 1,2-propanediol has been achieved, it suffers from major limitations such as expensive feed sugars and relatively low yields. It is hypothesized that algae sugars could serve as a feedstock for the microbial synthesis of 1,2-propanediol, thereby reducing production costs and enhancing sustainability.

Algal biomass produced from an Algal Turf Scrubber® has proven to have significant potential as a source of fermentable materials. However, …

Your Media Speak So Loud I Can't Hear A Word You're Saying: Impact Of Media And Media Selection On Performance, Martin Hassell

Graduate Theses and Dissertations

With the proliferation of communication media and technologies available, it is important for teams to understand the influence of these media on the performance of their communications. Additionally, it is important for researchers to understand how teams choose and use media. Literature on communication media impacts and communication performance has been somewhat fragmented, and researchers have used different theories and paradigms to study this problem. Researchers still do not have a full understanding of how media influences communication, whether teams recognize and select appropriate media for their communication needs, and what makes some communication more effective, irrespective of the communication …

The Legitimation Of Novel Technologies: The Case Of Nanotechnology, Anastasia E. Thyroff

Graduate Theses and Dissertations

Nanotechnology is the control, manipulation, and application of matter on an atomic and molecular level. The technology is complex and confusing to consumers, and its long-term safety and effect on the human body, as well as the environment, are unknown. However, for the past decade, nanotechnology has been used to develop consumer products and food with novel and attractive attributes.

Since nanotechnology is still not well known, it is not legitimized; that is, it has not been deemed safe and accepted by society. However, the market for nanotechnology is in the legitimation process. It will take an entire network of …

Evaluation Of Broiler Litter Heat Production During Windrowing & Nitrogen Based Gas Emission Mitigation Using Biofilter, Min Lei

Graduate Theses and Dissertations

Ammonia emission from animal feeding operations (AFOs) has negative effects on environment and animals' health. Thus measuring and mitigating ammonia emission from AFOs is important for environmental protection. In chapter I, different ammonia measurements were discussed and a mitigation technology- biofilter was represented.

In-house windrowing of built-up litter has been used by broiler producers to reduce pathogen loads and rejuvenate litter for the next flock. When litter is piled up for an extended period during downtime, heat generated by the litter pile can become a substantial heat source due to the metabolism of microorganisms. In chapter II, heat production rates …

The Effects Of The Bi-Partisan Campaign Reform Act On The Process Of The Campaign Finance In The Presidential Nomination Process, Karen Sebold

Graduate Theses and Dissertations

The Bipartisan Campaign Reform Act increased the individual donor limit to $2,000 per candidate per election and indexed the limit for inflation every two years. The primary research question guiding this study is how has the increase in the donor limit affected donor behavior. Answering this question should allow a determination to be made about how donors have responded to the increased donor limit. Understanding how donors responded to the doubled limit is important because it provides evidence on the intersection of wealth inequality and political influence. To answer the research question this study considers how the increased donor limit …

Utilizing A Modular Approach To Gamification To Improve Nutrition And Fitness In Children, Chad Richards

Graduate Theses and Dissertations

Obesity is a worldwide epidemic that affects adults and children, impacts over 30% of the population in several states of the U.S., damages national economies, and is a factor in four out of the six of the leading causes of death, including diabetes and heart disease. Obesity is preventable: solution approaches include better education, more exercise, better nutrition, and changing eating habits. Still, it is difficult for many people to remain interested enough to educate themselves and to learn new behaviors to change their eating and exercise habits.

Gamification is a relatively new research area that involves using video game …

The Use Of Non-Traditional Technologies To Improve The Efficiency And Sustainability Of Modern Poultry Production, Christopher Pixley

Previous research in college athletics has tended to focus only on these two sports and their economic impacts, disregarding any Social or general negative impacts they may bring with them. The purpose of this study was to develop a deeper understanding of students' perceptions of Social, economic and general negative impacts associated with hosting a NCAA baseball regional or super regional on the host campus and community. Hosting NCAA postseason events on campus is rare for many universities, so it is important to study how students …

Comparison Of Potential Salmonella Portals Of Entry And Tissue Distribution Following Challenge Of Poultry, Gopala Krishna Kallapura Sheshagiri

Graduate Theses and Dissertations

The following studies evaluated our hypothesis that transmission by the fecal-respiratory route may be a viable portal of entry for Salmonella and could explain some clinical impressions of relatively low-dose infectivity under field conditions in relation to the requisite high oral challenge dose that is typically required for infection of poultry through the oral route in laboratory studies. Initial field reports indicating tracheal sampling to be a sensitive tool for monitoring Salmonella infection in commercial flocks, suggested that tracheal contamination could be a good indicator of Salmonella infection under commercial conditions. Further, a usual assumption regarding airborne Salmonella reaching the …

Decoding Literary Aids: A Study On Issues Of The Body, Masculinity, And Self Identity In U.S. Aids Literature From 1984-2011, Alexander Shimon Abrams

Graduate Theses and Dissertations

Rather than waiting decades to respond, novelists of nearly every literary genre began conceptualizing the AIDS epidemic shortly after the first documented case of the virus in the United States in 1981. Writers, feeling a sense of urgency, wasted little time constructing didactic texts that differ from much historical fiction in that they were written as the tragedy they are commenting on occurred. However, AIDS literature has changed as the disease has spread well beyond the gay communities of San Francisco and New York, causing people to reexamine their longstanding beliefs on masculinity, sexuality, and body politics.

Biodiesel Transesterification Byproducts As Soil Amendments, Solomon Parker

Graduate Theses and Dissertations

For every ten kilograms of biodiesel that is produced from the transesterification of vegetable oil, approximately 1 kg of glycerol is produced as a byproduct. Also known as glycerin, it is a chemical used in many products including cosmetics, foods, and desiccants. However, the crude glycerol created during biodiesel production is tainted with potassium hydroxide and methanol making it unsuitable for commercial use without costly refinement. With increase in production of biodiesel driven by rising fuel prices, the market has become glutted with glycerol and it is on the threshold of becoming a waste product. Common methods for disposing glycerol …

Toile, Dilenia Garcia

Graduate Theses and Dissertations

Toile is a painting series that explores constructions of taste and the semiotics of manufactured fabrics. Through the use of irony, paradox and deconstructions of rhythm, shape, color and form, the paintings are a response to the formal and historical content in the fabric. The idyllic landscape, notions of identity, sexism and liminality are some of the themes considered in the series. The paintings in this exhibition attempt to correct and mediate outdated models of representation through the exploration of painting as a process that is open and malleable.

Cycle, Nichole Annette Howard

Graduate Theses and Dissertations

Cycle is the exhibition of a year-long project that experiments with growing food and medicinal herbs. Alongside an exploration of plant growth, I transfer iconic cultural objects of daily life from plastic to ceramics. Using material culture as a physical and conceptual platform, this re-contextualization of objects offers a radically different view of use and meaning. I transform the soda-filled, plastic Big Gulp cup into a terra planter filled with new life.

My working method involves making molds of Big Gulp plastic cups and transferring the form into a traditional plant growing material, terra cotta. I then germinate seeds inside …

Institutional Distance And Entry Mode: How Do Emerging-Market Multinational Companies Overcome Competitive Disadvantages In A Developed Market?, Ru-Shiun Liou

Graduate Theses and Dissertations

As latecomers to global business competition, emerging-market multinational companies (EMNCs) utilize cross-border merger and acquisitions to swiftly acquire strategic assets, such as brands and distribution channels, compensating for their competency deficiency. Developed markets with well-established firms and well-developed market-supporting institutions become important destinations for EMNCs' strategic asset-seeking investments. Institutional distance, national differences in the institutional environment, constitutes a major source of competitive disadvantage for foreign firms competing with indigenous firms. Foreign firms need to overcome the challenges of unfamiliarity, relational, and discriminatory hazards to establish legitimacy in the host market. Compared to established multinationals that originate from other advanced markets …

Subtle Messages: An Examination Of Diversity In The Illustrations Of Secondary Level One French Textbooks, Stephen Richard Adamson

Graduate Theses and Dissertations

Textbooks in all content areas have been criticized for the hidden curriculum that subtly teaches messages, which elevate some cultural groups while diminishing the efforts and contributions of other cultural groups. Research into the hidden curriculum and inclusion of diversity in French textbooks has been limited. The present study focused on the inclusion of diversity in terms of race/ethnicity, gender, socioeconomic status, disability, and body size present in the illustrations of the three newest French One textbooks. Results indicate that diversity has increased but the diversity within the illustrations does not always mirror the actual demographics of the United States …

Expression, Production, And Purification Of Novel Therapeutic Proteins, Mckinzie Shea Fruchtl

Graduate Theses and Dissertations

Interest in the production of recombinant proteins consisting of collagen binding domain (CBD) fused to a bioactive material has increased due to the targeting/attachment capabilities of CBD. For example, CBD fusions can be applied to the reversing of bone density loss and the repair of the eardrum, specifically, by choosing an appropriate fusion partner (parathyroid hormone or epidermal growth factor). The production of CBD fusions was examined using batch and fed-batch culturing of Escherichia coli to express the fusion proteins, and affinity chromatography to isolate the final product.

Different medium formulations, feeding strategies, and induction methods were tested in order …

Feet In The South, Eyes To The West: Fort Smith Enters The Sunbelt, Adam Morrison Carson

Graduate Theses and Dissertations

This paper examines the political realignment of Fort Smith, Arkansas and argues that the standard historiographical argument about the process of realignment does not explain what occurred in this city. Much of the historiography of political realignment currently revolves around the belief in a white backlash against the federal government and the national Democratic Party for their support of African American civil rights. Though historians have moved toward a "suburban synthesis" that downplays the backlash thesis, historians still argues that many white southerners moved to the suburbs to avoid integration.

I argue that this process did not occur in the …

After Orwell: Totalitarian Fears And The English Political Novel, 1950-2010, Jackson Ayres

Graduate Theses and Dissertations

After Orwell: Totalitarian Fears and the English Political Novel, 1950-2010 gives a coherent account of the English political novel after World War II, a critical narrative absent from current scholarship. I contend that George Orwell's Nineteen Eighty-Four (1949), a touchstone for political fiction, is underwritten by Orwell's conflicted attitude toward politics: despite embracing politics as the necessary means to genuinely improve people's lives, he also remained suspicious of politics' apparently inherent potential to diminish or even eliminate autonomy. Orwell's simultaneous attraction and vigorous resistance to politics, I argue, is tied to broader contemporaneous anxieties over political and cultural totalization. Such …

Theoretical Underpinnings Of Jury Decision Making In Excuse Defense Cases, Christopher Sean Peters

Graduate Theses and Dissertations

In the typical criminal trial, a defendant is trying to prove he/she is not guilty because they were not the individual that committed the crime. However, another type of defense exists in which the defendant admits they were the culprit, but provides an excuse in an attempt to avoid criminal punishment. These so called "excuse defenses" include insanity, involuntary intoxication, age, and entrapment. In all cases, juries are required to determine whether the defendant had sufficient mental capacity to form the intent to commit the crime. Although jury decision making is a popular research area in psychology, relatively little has …

Citizen Support For Northern Ohio Community College Funding Initiatives During An Economic Recession Recovery, Patricia Flores

Graduate Theses and Dissertations

The current research, Citizen Support for Northern Ohio Community College Funding Initiatives during an Economic Recession Recovery, asks the question: Do the citizens of Northern Ohio support community college funding during difficult economic times? Based on the theory of Stakeholder Analysis, the purpose of this concurrent, mixed-methods study was to investigate stakeholder support of community college funding initiatives, particularly for levy-funded community colleges that rely on the voting public to voluntarily contribute property taxes to support their institutions.

A comparison of Ohio community college statements and survey responses regarding stakeholder needs and beliefs indicated a significantly higher instance of …

New Effects Of Aging And Lattice Intercalation On Surface Properties Of Titanate Nanobelts, Roger Williams

Graduate Theses and Dissertations

Titanate nanobelts (NBs) have structural characteristics beyond that of clays. Due to a negatively charged lattice matrix of edge-shared TiO6-octahedra, the location of intercalated cations within the interlayer space may dictate the charge-conductions. This environment may in turn govern the lattice-framework's stability and surface properties, based upon our preliminary

data.

On that basis, these nanomaterials have been found in our lab to possess superb biological compatibility that is closely related to the types of the intercalated cations. In addition, a prolonged agitation was proven to enable us to manipulate the titanate NBs' length. In a parallel study, a ripening was …
