Molecular Characterization Of A Subset Of Krab-Zfps, Alain. Chamoun Jan 2010

Molecular Characterization Of A Subset Of Krab-Zfps, Alain. Chamoun

Electronic Theses and Dissertations 2010 - 2019

There are approximately 20,000 genes in the human genome. Around 2% of these genes code for transcriptional repressors known as KRAB-ZFPs. It is already known that Zinc-Finger Proteins contain two main functional domains at either end of the polypeptide. In today's database, you will find a KRAB (Kruppell-associated Box) domain at one end and a tandem array of Zinc-finger repeats at the other end. The carboxyl terminal tandem Zinc-finger repeats function as sequence-specific DNA-binding domains. The amino terminal KRAB domain serves as a repressor domain, which will recruit a co-repressor termed KAP-1 (KRAB Associated Protein-1). Located in between these two …

Molecular Characterization Of Arid And Ddt Domain, Emmanuel. Macdonald Jan 2010

Molecular Characterization Of Arid And Ddt Domain, Emmanuel. Macdonald

Electronic Theses and Dissertations 2010 - 2019

Transcriptional regulation of genes is vital to cell success making it an important aspect of research. Transcriptional regulation can occur in many ways; transcription factors bind to the promoter region and block transcription, disrupt an activator protein, or interact with histones to lead to higher order chromatin. Plant HomeoDomain can recognize and bind to different methylation states of histone tails. PHD proteins use other functional regions to carry out functions. Two associated domains having DNA-binding capacity were characterized in this study; the ARID domains of JARID1A and JARID1C and the DDT domains of BAZ1A, BAZ1B and BAZ2A. These genes are …

More Branches On The Oldest Tree, David. Bethea Jan 2010

More Branches On The Oldest Tree, David. Bethea

Electronic Theses and Dissertations 2010 - 2019

On Monday August 29, 2005, Hurricane Katrina made landfall in Southeast Louisiana bringing with it destruction to much of the Gulf Coast. While New Orleans, one of America's most culturally and artistically significant cities, was spared a direct hit, the subsequent flood devastated much of the city, home to many musicians. The devastation and stress from the storm established a situation and a motivator for creative response, and this dissertation illustrates that the music these musicians produce is a manifestation and continuation of New Orleans' cultural atmosphere. The city's historical allowance and celebration of freedom of expression permits New Orleans' …

Neural And Behavioral Correlates Of Song Prosody, Reyna Leigh Gordon Jan 2010

Neural And Behavioral Correlates Of Song Prosody, Reyna Leigh Gordon

Electronic Theses and Dissertations 2010 - 2019

This dissertation studies the neural basis of song, a universal human behavior. The relationship of words and melodies in the perception of song at phonological, semantic, melodic, and rhythmic levels of processing was investigated using the fine temporal resolution of Electroencephalography (EEG). The observations reported here may shed light on a ubiquitous human experience and also inform the discussion of whether language and music share neural resources or recruit domain-specific neural mechanisms. Experiment 1 was designed to determine whether words and melody in song are processed interactively or independently. Participants listened to sung words in which the melodies and/or the …

Of Offal, Corpses, And Others, Robert William Jones Jan 2010

Of Offal, Corpses, And Others, Robert William Jones

Electronic Theses and Dissertations 2010 - 2019

This thesis examines two works (My Journey to Lhasa and Magic and Mystery in Tibet) by Alexandra David-Neel. These works subvert the self/other dichotomies both necessary to and critiqued by postcolonial theory. Central to this study is an examination of a claim by His Holiness the XIV Dalai Lama that David-Neel creates an "authentic" picture of Tibet. In order to do this the first chapter establishes a working definition of authenticity based on both Western philosophy and Vajrayana Buddhism. This project argues that the advanced meditation techniques practiced by Alexandra David-Neel allow her to access a transcendent self that is …

Perceptions Of Animal Minds, Lauren N. Maurer Jan 2010

Perceptions Of Animal Minds, Lauren N. Maurer

Electronic Theses and Dissertations 2010 - 2019

Previous research into people's perceptions of animals suggests that people view animals most favorably when they perceive them as being mentally like humans. This thesis examined whether animals perceived as threatening are still seen to be mentally similar to humans, but more likely to experience mental states associated with anger and aggression. Using three separate measures of people's perceptions of animals, including one designed for this study, it was found that participants did indeed view the mental lives of animals differently when those animals were perceived to be threatening. Examination of the effect of the animal chosen showed that some …

Power Of Memory, Tajana. Bjellos Jan 2010

Power Of Memory, Tajana. Bjellos

Electronic Theses and Dissertations 2010 - 2019

This thesis provides a rhetorical analysis of the Western representation of the Kosovo conflict and its resolution in the year 1999. By reviewing political, scholarly and media rhetoric, the thesis examines how the dominant narrative of "genocide in Kosovo" was created in Western discourse, arguing that it gained its persuasive force from the legacy of the collective memory of the Holocaust. Using the framework of Kenneth Burke's theory of Dramatism and Walter Fisher's theory of the narrative paradigm, this thesis aims to understand how language, analogy and collective memory function in rhetoric to shape audience perceptions and guide political and …

Power Of Subtext And The Politics Of Closure, Adam. Berzak Jan 2010

Power Of Subtext And The Politics Of Closure, Adam. Berzak

Electronic Theses and Dissertations 2010 - 2019

This thesis explores the ways that certain artists-including Joseph Conrad, Alan Moore, Richard Attenborough, and Francis Ford Coppola-break from their inherited traditions in order to speak from an alternative perspective to western discourse. Conventional narrative formulas prescribe that meaning will be revealed in a definitive end, but all of the texts discussed reveal other avenues through which it is discerned. In Heart of Darkness, the tension between two divergent narratives enables Conrad to speak beyond his social context and imperialist limitations to demonstrate that identity is socially constructed. In Watchmen, Moore breaks from comic convention to illustrate ways meaning may …

Preacher's Cave, Jane S. Day Jan 2010

Preacher's Cave, Jane S. Day

Electronic Theses and Dissertations 2010 - 2019

Preacher's Cave, an archaeological site in North Eleuthera, Bahamas, is arguably one of the most important historical places in that country. This large cave, isolated in a natural setting, has long been associated in the popular imagination with the first English colonists who shipwrecked in the Bahamas in 1648 and laid the foundation for the modern nation. Before the present work, no systematic scientific archaeological work had ever been conducted at this site. While Project Director for the Preacher's Cave archaeological investigations in 1991, 1992, 2005, 2006, and 2007, I acted as liaison between the Bahamian Government, local island constituents, …

Preventing The Next Abu Gharib, Paul. Hofacker Jan 2010

Preventing The Next Abu Gharib, Paul. Hofacker

Electronic Theses and Dissertations 2010 - 2019

The cruelty of Military Police guards at Abu Ghraib prison contributed to American shame and questions regarding how such cruelty emerges. The accepted approach of "situational attribution theory" - based upon Zimbardo's (1973, 2007) social psychological perceptions and results of the Stanford Prison Experiment - proposed that personality or "disposition" has little role in the emergence of such cruelty. Termed "institutional cruelty," this manuscript presents the possibility that understandings and preventive measures afforded by situational attribution theory can be extended via acknowledgement of a greater role played by disposition. Psychoanalytic and object relations approaches are presented to this end. The …

Rastafari Presence In Toni Morrison's Tar Baby, Beloved, And Song Of Solomon, Nicole Racquel Carr Jan 2010

Rastafari Presence In Toni Morrison's Tar Baby, Beloved, And Song Of Solomon, Nicole Racquel Carr

Electronic Theses and Dissertations 2010 - 2019

Literary scholars frequently analyze the allusions to Western Christianity apparent in Toni Morrison's novels, but these studies overlook the ways in which some of her novels are informed by a Caribbean presence. This study argues that Rastafari themes, symbols, and ideologies are recurrent in Toni Morrison's Tar Baby, Beloved, and Song of Solomon. Rastafari is a social movement primarily concerned with restoring the image of Africa to a holy place. A Rastafari analysis of these texts broadens the literary spectrum to suggest that these novels highlight Morrison's attempt to write about the multifaceted element of the black community, which remains …

Regional Differences In Migratory Activity By Hatchling Loggerhead Sea Turtles (Caretta Caretta), Jeffrey Guertin Jan 2010

Regional Differences In Migratory Activity By Hatchling Loggerhead Sea Turtles (Caretta Caretta), Jeffrey Guertin

Electronic Theses and Dissertations 2010 - 2019

There are four distinct subpopulations of loggerhead sea turtles (Caretta caretta) in Florida as determined behaviorally by geographic fidelity, and genetically by mitochondrial haplotypes. The South Florida subpopulation consists of females nesting on the southeastern and southwestern coasts of Florida and their offspring. Previous research shows that west coast hatchlings exhibit higher levels of nocturnal swimming during the postfrenzy period than east coast hatchlings. This study attempted to determine how these differences in migratory behavior develop. A reciprocal translocation experiment was conducted to distinguish between environmental and genetic factors. No consistent differences in hatchling swimming behavior were seen based on …

Retrospective Analysis Of Sea Turtle Nest Depredation Patterns At Canaveral National Seashore, Florida, Rachel. Welicky Jan 2010

Retrospective Analysis Of Sea Turtle Nest Depredation Patterns At Canaveral National Seashore, Florida, Rachel. Welicky

Electronic Theses and Dissertations 2010 - 2019

Nest predation can significantly reduce hatchling recruitment in sea turtle populations. This study uses 20 years of data from Canaveral National Seashore, Florida, which has pristine and altered beaches. Chi-square tests were used to determine if secondary predation events were related to the nest's primary depredation event. To determine if human beach use and nest predation are spatially or temporally linked, we ranked human beach use and examined predation frequency across all screened and marked nests (n=40,441). Lastly, I quantified nest predation risk spatially and temporally. I found that primary predation increases the chance of a nest suffering subsequent predation. …

Risk Of Sperm Competition Moderatres Men's Relationship Satisfaction And Interest In Their Partner's Copulatory Orgasm, Vincent M. Bates Jan 2010

Risk Of Sperm Competition Moderatres Men's Relationship Satisfaction And Interest In Their Partner's Copulatory Orgasm, Vincent M. Bates

Electronic Theses and Dissertations 2010 - 2019

Sperm competition occurs when the sperm of multiple males concurrently occupy a female's reproductive tract and compete for fertilization. Sperm competition may have been a recurrent adaptive problem over human evolutionary history. Women's orgasm may facilitate retention of a particular man's sperm. I therefore hypothesized that men experiencing greater sperm competition risk will be particularly interested in the occurrence of their partner's copulatory orgasm. Men who are more satisfied with and invested in their relationship may experience greater costs in the event of sperm competition and potential cuckoldry. Therefore, these men may be more interested in ensuring their partner's copulatory …

Sensitivity Analysis Of Blind Separation Of Speech Mixtures, Savaskan. Bulek Jan 2010

Sensitivity Analysis Of Blind Separation Of Speech Mixtures, Savaskan. Bulek

Electronic Theses and Dissertations 2010 - 2019

Blind source separation (BSS) refers to a class of methods by which multiple sensor signals are combined with the aim of estimating the original source signals. Independent component analysis (ICA) is one such method that effectively resolves static linear combinations of independent non-Gaussian distributions. We propose a method that can track variations in the mixing system by seeking a compromise between adaptive and block methods by using mini-batches. The resulting permutation indeterminacy is resolved based on the correlation continuity principle. Methods employing higher order cumulants in the separation criterion are susceptible to outliers in the finite sample case. We propose …

She Just Snapped, Megan. Tomei Jan 2010

She Just Snapped, Megan. Tomei

Electronic Theses and Dissertations 2010 - 2019

Snapped, a documentary style show profiling female killers, is one of Oxygens longest running hit franchises. This thesis analyzes, through both the frames of feminist theory and rhetoric, the way the show perpetuates and plays upon the myth of feminine evil as well as the stereotype of women as weak, hysterical agents in need of control. Snapped showcases women who start out as seemingly normal but then enact horrendous crimes. The use of women that the audience can identify with but then later fear creates a cathartic experience in which female audience members can be vicariously cleansed of any dangerous …

Snapping Shrimp Protect Host Anemones From Predators, Amber. Mccammon

Electronic Theses and Dissertations 2010 - 2019

The sea anemone Bartholomea annulata, is an ecologically important member of Caribbean coral reefs. This anemone serves as symbiotic host to crustacean associates, some of which may control parasite loads by "cleaning" reef fishes. Associates may gain protection from predation by dwelling with anemones. B. annulata was the most abundant anemone documented on three reefs, with 52% host to crustacean symbionts. Of those occupied by multi-species groups, 92% included Alpheus armatus shrimp. A. armatus is an important anemone associate providing protection to the anemone from predators such as Hermodice carunculata, in laboratory and field trials. H. carunculata can completely devour …

South Asian Diaspora In The Caribbean, Savena. Budhu Jan 2010

South Asian Diaspora In The Caribbean, Savena. Budhu

Electronic Theses and Dissertations 2010 - 2019

This dissertation proposes a two-part thesis on the South Asian diaspora in the Caribbean within contemporary Indo-Guyanese literature. First, Indo-Guyanese writers such as David Dabydeen, Oonya Kempadoo, and Narmala Shewcharan are using the genre of historical fiction to posit counter narratives that undermine dominant narratives of South Asian culture and gender roles. Second, even as these writers struggle against dominant narratives, their texts reinscribe the colonial discourse and rearticulate racial stereotypes. As argued in this dissertation, the dismal historical realities of ethnic tensions and failed anti-colonial tactics do not sufficiently address the flexible strategies often chosen by the characters and …
