It was predicted that the intensity of emotional stimuli would moderate the relationship between nap restriction and the magnitude of emotional responding. Specifically, following nap restriction, the emotional responses to stronger stimuli would be amplified, while the emotional responses to weaker stimuli would be reduced. Emotional stimuli, were classified into four categories: strong negative, weak negative, weak positive, and strong positive. Facial electromyography was measured to reflect preschoolers’ emotional responses. The results indicated emotional responses to both strong negative and positive stimuli were …

Making Meaning Of The Reel: The Media's Portrayal Of Community Colleges, Jena Lee Hawk

Dissertations

Due to its seemingly unclear and ambiguous mission, the community college has somewhat of a stigma attached to it as a four-year institution defines the American college experience (LaPaglia, 1994). Although only a few studies concerning media portrayals of community college students have been published within the last twenty years, the existing studies (Bourke, Major, & Harris, 2009; LaPaglia, 1994; Tucciarone, 2007) have failed to address if the media’s portrayal of community colleges influences students’ decisions or actions with regard to enrolling in a two-year institution. Using the theoretical framework of critical media literacy, the researcher will examine if media …

Fluorine Containing Uv-Curable Materials For Advanced Transport Applications, James Thomas Goetz

Dissertations

The characterization of structure, thermal, gas transport, and free volume properties of two unique UV cured polymeric systems are studied and reported. In the initial pursuit of waterproof high water vapor transport membranes, it became apparent that the UV curing of fluorinated materials yielded routes to develop unique materials that fundamentally challenge conventional models for free volume and light gas transport behavior. UV-curing provides a means to rapidly “lock-in” morphologies that are accessible in the small molecule, monomer phase but rapidly become kinetically inaccessible when constraints such as covalent bonding and cross linking limit motion in the polymer system. This …

Using the three tenets of Morais and Ogden (2009), as well as a definition developed based on research, this researcher sought to discover …

Consumers And Their Celebrity Brands: How Narratives Impact Attachment Through Communal Relationship Norms, Bennie Eng

Dissertations

Whether they are gracing movie screens, tweeting about the size of their baby bump, or being photographed by the paparazzi in their swimwear accidently on purpose, celebrities compel consumers to care. Despite the pervasive consumer interest in celebrities, the fundamental process of how and when consumers develop relationships with and attachments to them is a subject that has been underexplored by marketing scholars, a discipline whose activities are often turbocharged by celebrities. In this research project, celebrities are viewed as brands in and of themselves, and accordingly, are examined through the prism of marketing's brand relationship literature. Drawing upon that …

With the penetration of online and social media, the participatory culture of South Korea has significantly and qualitatively changed. During the last 10 some years, citizens actively used Internet media, such as online and social media, in mobilizing people for social and political causes. In recent elections, the use of Internet media has been considered one of the decisive factors of turnout …

Elucidation Of The Role Of Auxin-Input Pathways In Auxin Homeostasis., Gretchen Spiess

Dissertations

Auxin is a phytohormone involved in cell elongation and division. Levels of indole-3-acetic acid (IAA), the most abundant auxin, are tightly regulated through biosynthesis, degradation, sequestration, and transport. Sequestration of IAA occurs in reversible processes by adding amino acids, polyol or simple alcohols, or sugars, forming IAA conjugates, or via a two-carbon elongation forming indole-3-butyric acid (IBA). These forms of auxin have decreased activity and are located in multiple organelles. Using a combination of molecular and genetic tools, I examined how these storage forms are working together to contribute to overall IAA levels and IAA response in both the model …

“What I Care Bout Dogs?” How The Hegemony Of The English Language Colonizes Marginalized Groups, Richard Eric Andrews

Dissertations

Language has always seemed to play a pivotal role in the identity of individuals and groups who are relegated to the status of other by members of the dominant group. The misshapen identities of the others are further exacerbated by systems and structures in place, like education, which ensure the continued hegemonic status of dominant groups. Not being a part of the dominant group, and yet being required to conform to their standards, can be confusing for those on the outside. The character Celie, expressed this confusion, “Whitefolks all over them, talking bout apples and dogs. What I care bout …

Supply Chain Relationships In Procurement: Is Collaboration Reality?, Wesley S. Boyce

Dissertations

Supply Chain Management (SCM) often requires independent organizations to work together to achieve shared objectives. This collaboration is necessary when coordinated actions benefit the group more than the uncoordinated efforts of individual firms. Collaboration is a key dimension of SCM, and it has numerous key dimensions of its own. These include information sharing, resource sharing, decision synchronization, incentive alignment, goal congruence, joint knowledge creation, and collaborative communication. Trust and commitment are also key factors that intertwine with these dimensions. Successful implementation of these types of collaborative relationships can lead to a collaborative advantage, where firms working together achieve greater success …

Privatization, State Militarization Through War, And Durable Social Exclusion In Post-Soviet Armenia, Anna Martirosyan

Dissertations

In the literature focusing on various aspects of the twin transitions from socialism, development and social well-being are mainly analyzed with respect to privatization process (Stark and Bruszt 1998, Applegate 1994); economic growth and institutional design (North 1990; Elster, Offe, and Preuss 1998; Kolodko 1999; Norgaard 2000); party and election politics, the development of social networks and deliberative associations (Stark and Bruszt 1998); and the bargaining power of labor (Bandelj and Mahutga 2005). While the importance of these factors is not underestimated, this study addresses a significantly understudied theme – social exclusion as a consequence of overweening state power. The …

Reassurance In Negative Space, Elizabyth A. Hiscox

Dissertations

This dissertation, Reassurance in Negative Space, is a poetry manuscript that deals with intersections of grief, gender, environment, and art in contemporary society. One of its guiding properties is an interest in the ekphrastic mode of composition: poetry in response to a work of visual art. American Hybrid poet-editor Cole Swensen discusses what has emerged as a new “hybrid” poetry that combines conventional approaches with more experimental forms; a stable first person narrator with fragmentation or juxtaposition, for example: “Hybrid poems often honor the avant-garde mandate to renew the forms and expand the boundaries of poetry—thereby increasing the expressive …

Like Oil And Water: How Federalism Muddies The Waters Of Interest Group Decision-Making, Melissa Shaffer-O’Connell

Dissertations

Federalism often creates additional decisions for interest groups in determining how best to advocate for their policy recommendations in the legislative process. Should they focus their advocacy at the local, state, or national level of government? What activities should they use at each level of government? This dissertation examines interest group behaviors in water quality policy in the Great Lakes region from 1940 to 2000, in oil policy in the Beaufort Sea region from 1970 to 2000, and in both policy areas in 2010-2013.

Biophysical Characterization Of The First Four Metal-Binding Domains Of Human Wilson Disease Protein, Alia V.H. Hinz

Dissertations

Wilson disease protein (WLNP) is a P_1b-type ATPase crucial for maintaining copper homeostasis in humans. Mutations in this protein result in the autosomal recessive disorder Wilson disease, a condition characterized by copper accumulation in the liver and brain. WLNP provides copper for incorporation into cuproproteins and exports excess copper into the bile for excretion. There are six metal-binding domains (MBDs) in WLNP, found within the first 650 amino acids of this 1,465 amino acid protein. Though each MBD has a different amino acid sequence, all MBDs possess a similar ferredoxin fold with a conserved hydrophobic core and a …

Wielding Eden: Early Modern Voices And The Appropriation Of Paradise, Adrienne Redding
