The Relationship Of Women's Magazines And Their Websites: A Comparative Analysis Of Print And Web Content, Allison Walker Ruff

Graduate Theses and Dissertations

With the digital expansion of magazines, it is essential to determine how a magazine's online and digital content compares to its print content. The editorial strategy for print content versus Web content could make a difference in consumers' brand attachment and loyalty to a magazine. Magazines must have a dynamic online strategy that offers a different experience than printed material in order to gain new relationships and strengthen those relationships people already have with the brand. A comparative analysis of the print content versus the online website content of four separate women's publications can help determine if each magazine is …

Taak In Sutik (I Want To Return), Jose Lopez Bribiesca

Graduate Theses and Dissertations

The purpose of this film is to have four descendants of the Maya tell their stories and through them, explain four difficult concepts facing the 21st century contemporary Maya:

* How do Mayan languages influence a worldview different than the westernized, globalized worldview?

* How do the media, especially through movies, portray the Maya and other indigenous groups unfairly?

* How have the descendants of the Maya coped with adapting to modernity while keeping their traditions intact?

* How will the four protagonists ensure the protection of their language and their culture when they return home?

An Extension To Particle Polarizability To Predict Coupling Behavior In Periodic Nanoplasmonic Arrays, Drew Dejarnette

Graduate Theses and Dissertations

Plasmonic nanoparticles organized in arrays interact to create spectral patterns which are amplified by individual particle polarizability. It was hypothesized that particle polarizability could be used as a predictor of spectral behavior from far-field interactions within the array. Inter-particle coupling produced an extraordinary peak in extinction efficiency at wavelengths equal to or larger than the single particle plasmon resonance peak. Interactions that produced constructive coupling were found to mimic changes in the particle polarizability model. Testing of the hypothesis was performed using the coupled dipole approximation with parametric characterization of array geometries, giving specific particle size and lattice constant combinations …

Phase Control In Atomic Coherence, Utsab Khadka

Graduate Theses and Dissertations

In this thesis, atomic coherence is used to enhance nonlinear optical processes in multi-level atoms. The multi-photon transitions are driven resonantly, and at the same time without absorptive losses, by using electromagnetically induced transparency (EIT), thereby allowing the study of χ⁽³⁾ and χ⁽⁵⁾ nonlinearities using weak driving fields. The coherently modified probe beam(s) and the atom-radiated signal fields arising from four- and six- wave- mixing (FWM and SWM) processes are measured in the spectral, temporal and spatial domains.

In a three-level ladder-type atomic system, multiple peaks having spectral asymmetries are observed in the EIT window as well as …

Gendered Effects On The Child Welfare Agency Decision-Making Process, Brandon Crawford

Graduate Theses and Dissertations

Previous research on child abuse and neglect suggests that there may be gendered relationships between child victims and case outcomes. Specifically, although agency practices may generally regard most male and female children as equally vulnerable, agency attributions regarding the culpability, need, and suitability of parents may be highly differentiated based on gender. Explanations for this pattern may lie in the cultural ideologies and organizational beliefs that distinguish between the perceived rights, responsibilities, and relative importance of mothering and fathering roles. That is, one function of Social service agencies is to uphold Social constructions of parenting and promote our larger cultural …

Genotypic And Phenotypic Diversity Of Pyricularia Oryzae In The Contemporary Rice Blast Pathogen Population In Arkansas, Lu Zhai

Vernon is obsessed with the distant past, particularly the time before the Louisiana Purchase and the Louisiana of …

Pixel; Ghost, John Christopher Kelley

Graduate Theses and Dissertations

Pixel; Ghost is an exhibition of video and sound installations that explore the creation, change, and degradation of memory, transitional states of mind, and family. The pieces are structured around cinematic clichés such as dream sequences, flashbacks and establishing shots, using them as a language to translate personal experience into something more universal.

In my work, Pixel refers to the individually active component of a larger system. A pixel itself changes and has its own characteristics, though these are ultimately subservient to its role in the larger system of a screen. The purpose and meaning of a pixel comes not …

It is my way of forming a connection with the rich history of craft and that of the studio potter. I draw inspiration from historical and contemporary ceramics, the …

Too Big Not To Fail: United States Corporate Media And The 2008 Financial Crisis, Justin Lars Bergh

Graduate Theses and Dissertations

This thesis investigates United States newspaper coverage of the 2008 financial crisis, with a particular focus on the debate that took place in press coverage surrounding the proposed 700 billion dollar Troubled Asset Relief Program (TARP). Specifically, this study aims to understand how, when faced with a crisis that threatened hegemony, the state and economic elites, working in and through media, were able to effectively convince the subordinate classes to consent to state intervention aimed at perpetuating a financial system that has historically profited from the relative financial insecurity of the subordinate classes. In order to understand media's role in …

Characterization Of Novel Histone H2b Mutants Associated With Chromosome Segregation Defects In Saccharomyces Cerevisiae, Thiruchelvam Rajagopal

Graduate Theses and Dissertations

Histones are small basic proteins that associate with DNA to form the basic unit of chromatin, the nucleosome. Histones H3 and H4 form a tetramer that is bound by two H2A-H2B dimers to form the histone octamer, to which approximately 146 bp of DNA wrap around to form the nucleosome. High resolution structural information and recent advances in the understanding of histone post-translational modifications have illuminated the many regulatory functions chromatin exerts in the cell, from the transcriptional control of gene expression to chromosome segregation. However, the specific role that histones play in these processes is not well understood. Previous …

A Typology Of Preadolescent Sexual Abusers Based On The Emerging Personality Patterns In The Millon Preadolescent Clinical Inventory, Sam Wallace

Graduate Theses and Dissertations

The purpose of this study was to develop a personality-based typology of preadolescents with sexual behavior problems based the Emerging Personality Patterns in the Millon Preadolescent Clinical Inventory (M-PACI, Millon et al., 2005). Grounding a typology in a theory driven personality system may offer clarity and specificity in understanding preadolescents with sexual behavior problems in a manner that has not yet been explored. A personality and theory driven typology could provide a more comprehensive framework for assessing and treating children who sexually abuse than any of the current taxonomic models.

The study used an ex post facto design with test …

Listeria monocytogenes an important foodborne pathogen that continues to be a serious problem for the food industry. This pathogen contaminates food primarily during post-harvest in the food-processing environment. Its ecology in the food-processing environment is not well understood but previous research has demonstrated the ability of L. monocytogenes to survive on food contact surfaces after cleaning and disinfection. The current study explored the attachment of three lactic acid bacteria (LAB) strains, Lactobacillus animalis , Lb. amylovorus and Pediococcus acidilactici , their combination in a cocktail, and their influence to prevent the attachment of L. monocytogenes at room temperature by examining …

Narrative Identity Within A Workers' Rights Organization, Emily Ann Hallgren

Graduate Theses and Dissertations

This research includes in-depth interviews and participant observation to examine the construction of narrative identity by the staff members and worker-members of a workers' rights organization in Northwest Arkansas. I seek to understand how the organization negotiates the broader cultural and institutional narrative identities with the personal narrative identities of the worker-members in a cultural context hostile toward undocumented immigrants. Further, I examine how the worker-members themselves both internalize and challenge the organizational, institutional, and cultural narratives about undocumented immigrant workers. Findings reveal that the staff members and the worker-members create different narratives for different purposes, though both are concerned …

High Frequency Characterization Of Carbon Nanotube Networks For Device Applications, Emmanuel Decrossas

Graduate Theses and Dissertations

This work includes the microwave characterization of carbon nanotubes (CNTs) to design new CNTs-based high frequency components. A novel developed method to extract the electrical properties over a broad microwave frequency band from 10 MHz to 50 GHz of carbon nanotubes (CNTs) in a powder form is performed. The measured scattering parameters (S-parameters) with a performance network analyzer are compared to the simulated one obtained from an in-house computed mode matching technique (MMT). An optimized first order gradient method iteratively changes the unknown complex permittivity parameters to map the simulated S-parameters with the measured one until convergence criteria are satisfied. …

Happily Ever After Take Two: Rewriting Femininity In Hybridization Fairy Tale Films, Megan Estelle Troutman

Graduate Theses and Dissertations

The tradition of fairy tales has evolved drastically over the past five hundred years. At the beginning of the 20th century, fairy tale cartoons became widely popular as an independent medium, as well as introductions to larger films. In 1937, Walt Disney started the tradition of fairy tale cinema with the release of Snow White. Since that time, Disney has released and re-released eleven princess fairy tale films. Critics and parents alike ridicule Disney for its depictions of women as submissive and subservient. Recent films have used fairy tale tropes, without referring to a specific classic tale, in order to …

An Experimental Test Of Trauma-Relevant Cue Exposure And Desire For Alcohol Among Adolescents, Heidemarie Blumenthal

Graduate Theses and Dissertations

A burgeoning literature suggests a linkage between adolescent traumatic event exposure and problematic alcohol use. Research conducted with adults indicates that exposure to trauma-relevant cues elicits a desire to drink; however, no work has examined this association among adolescents. The current study was designed to build upon and extend this line of work. Participants were 72 community-recruited adolescents (Mage = 16.19; 34.7% girls). Trauma-exposed (n = 47) and non-exposed (n = 25) youth were assigned to either a 3-minute experimental (voluntary hyperventilation) or control task (low-arousal picture viewing). Desire to drink was assessed (1) prior to task assignment, and (2) …

Aptamer-Based Spr Biosensor For Detection Of Avian Influenza Virus, Hua Bai

Graduate Theses and Dissertations

Rapid and specific detection of avian influenza (AI) virus is urgently needed with the concerns over the outbreaks of highly pathogenic H5N1 avian influenza in animal and human infection. Aptamers are artificial oligonucleic acid that can specifically bind to target molecules. They show comparable affinity for target virus and better thermal stability than monoclonal antibodies. Those advantages make aptamers promising candidates in diagnostic and detection applications. The goal of this research was to use DNA&ndashaptamer as the specific recognition element in a portable surface plasmon resonance (SPR) biosensor for detection of AI H5N1 virus in poultry.

A SPR biosensor was …

The Androgynous Tomboy: Adolescent Liminality In The Contemporary Southern Bildungsroman, Brooke Alexandra Shippee

Graduate Theses and Dissertations

The Androgynous Tomboy: Adolescent Liminality in the Contemporary Southern Bildungsroman is an analysis of the adolescent, specifically, of the young tomboy characters central to three Bildungsroman texts set in the American South during the twentieth century: Carson McCullers' The Member of the Wedding (1946), Bobbie Ann Mason's In Country (1985) and Dorothy Allison's Bastard Out of Carolina (1993). I seek to challenge the very notion of the conventional tomboy within the coming of age literary genre by defining these youths as androgynous, rather than as young individuals who assume a singular gender opposite of their biological sex. Throughout my work, …
