Reproductive Isolation In Drosophila: From Behavior To Genome, Daina Ma Jan 2010

Reproductive Isolation In Drosophila: From Behavior To Genome, Daina Ma

Biology Dissertations - Archive

In this study, I investigate factors underlying reproductive isolation in Drosophila. I begin (Part I) by measuring behavioral isolation between Zimbabwe and cosmopolitan D. melanogaster, and asking the following questions: What is the pattern? What are the sensory cues leading to isolation? In Part II, I present results of a genomic screen for candidate genes underlying behavioral isolation between Zimbabwe and cosmopolitan D. melanogaster. Then I turn to the genomic causes of postzygotic reproductive isolation (Parts III and IV): What are the possible genes associated with hybrid sterility? What are the relationships between fertility/sterility and genotypes and allelic expression? What …

The Unheard Voice Of Immigrant Muslim Women In The United States Post-9/11/2001, Erin Alkhaolany

Philosophy & Humanities Theses - Archive

Immigrant Muslim women in the United States experience difficulties, as most immigrants do, with integration into a new society. In order to better depict the reality that these women are actually experiencing a lack of voice to demonstrate their difficulties and subsequently receive assistance, I utilize intersectionality feminist theory to differentiate categories where analyses can lead to improved assimilation and ease in integration for these women. Specifically, the intersections of aspects such as religion, race, class, gender, and ethnicity are included as major points of concern in dissecting what it means to be an immigrant Muslim woman in the United …

Repression, Language, Resistance: An Analysis Of Jacksonian America Through Foucauldian Lens, Brandon D. Vestal Jan 2010

Repression, Language, Resistance: An Analysis Of Jacksonian America Through Foucauldian Lens, Brandon D. Vestal

Philosophy & Humanities Theses - Archive

During the age of Andrew Jackson (1824-1845), the United States experienced a social and political sea change that would leave the country changed forever. As Jackson served his country first as general and ultimately as president, his name came to represent a new brand of American Democracy. This expression of democracy that emerged during Jackson's life extended a politcal hand to the "common man" as represented by the yeoman farmer and urban laborer. However, as universal suffrage was granted to these common white men and the politcal landscape shifted from an elitist republic to a meritocracy, there were other politically …

Driving Force: An Exploration Of Texan Prius Drivers, Heather Champeau

Sociology & Anthropology Theses - Archive

The purpose of this study was to examine what Prius owners use their vehicle to tell the world about themselves and to discover whether this varies by gender. This was explored through the lens of situational simulation, a blending of Baudrillard's (1983) theory concerning simulation and current literature concerning gendered consumption of environmental goods and awareness.In-depth interviews with fourteen participants were the main source of data. The interview schedule was loosely based on the work of previous researchers (Heffner, Kurani and Turrentine 2007), though a unique questionnaire was included after interviews were complete. Participants were gathered using snowball methodology in …

Media Framing And Social Movements: A Case Study Of The Red Shirt Movement In Taiwan, Wen-Hsin Ho Jan 2010

Media Framing And Social Movements: A Case Study Of The Red Shirt Movement In Taiwan, Wen-Hsin Ho

Sociology & Anthropology Theses - Archive

In my thesis, I use the social movement literature and framing theory to examine the rapid rise and fall of Taiwan's Red Shirt social movement in 2006. The movement was against President Chen Shui-bian, who was accused of corruption; its main goal was to oust President Chen from office. From its inception in August 2006 to its demise in October 2006, this social movement swelled to include several hundred thousand participants, but collapsed nearly as quickly as it rose to prominence. The Red Shirt movement and the surrounding events were extensively covered by television, print, and Internet media. Many scholars …

Vietnamese Amerasians: A Study Of Identity Construction, Ky-Giao C. Nguyen Jan 2010

Vietnamese Amerasians: A Study Of Identity Construction, Ky-Giao C. Nguyen

Sociology & Anthropology Theses - Archive

We define who we are by defining who we are not (Daniel 1996). What happens when we don't know who we are not, how can we determine who we are? What if the markers of family connections, community alliances and citizenship are missing and there are no peers with whom to make comparisons? "What are you? Where are you from?" Hispanic, Filipino, sometimes even Native American rather than Asian, are ethnicities often ascribed to Vietnamese Amerasians (children of Vietnamese and American parents). Curiously, for such a personal question, the reaction from others to the response "Vietnamese Amerasian" is often rejection …

Voice And Valence-Altering Operations In Falam Chin: A Role And Reference Grammar Approach, Deborah King Jan 2010

Voice And Valence-Altering Operations In Falam Chin: A Role And Reference Grammar Approach, Deborah King

Linguistics & TESOL Dissertations - Archive

This dissertation describes and analyzes voice and valence-altering operations in Falam Chin, a Tibeto-Burman language of Burma. The data is explained within the framework of Role and Reference Grammar (RRG), which supplies several key concepts particularly useful for generalizing the behavior of the Falam Chin operations. The first is RRG's system of semantic decomposition, based on Dowty (1979), which is used to formulate each predicate's underlying logical structure (LS). Second is the concept of macroroles, generalized semantic roles actor and undergoer, which are assigned to the arguments of a predicate according to a hierarchy of LS positions. M-transitivity refers to …

Advanced Software Testing Techniques Based On Combinatorial Design, Wenhua Wang Jan 2010

Advanced Software Testing Techniques Based On Combinatorial Design, Wenhua Wang

Computer Science and Engineering Dissertations - Archive

Combinatorial testing refers to a testing strategy that applies the principles of combinatorial design to the domain of software test generation. Given a system with k parameters, combinatorial testing requires all the combinations involving t out of k parameters be covered at least once, where t is typically much smaller than k. The key insight behind combinatorial testing is that while the behavior of a system may be affected by many parameters, most faults are caused by interactions involving only a small number of parameters. Empirical studies have shown that combinatorial testing can dramatically reduce the number of tests while …

Information-Driven Data Gathering In Wireless Sensor Networks, Jing Wang Jan 2010

Information-Driven Data Gathering In Wireless Sensor Networks, Jing Wang

Computer Science and Engineering Dissertations - Archive

Since the advance of wireless technology enables the mass production of low-cost, small-sized sensor nodes, sensor nodes can be densely deployed in an area for high tolerance to node failure or to achieve better coverage statistically. The redundancy of sensor nodes results in the temporal and spatial correlation of sensory data, which motivates the information-driven data gathering approaches for wireless sensor networks (WSNs).Since existing approaches target at the sensory data that are already highly correlated with each other, little attention has been paid to the idea of changing the sampling schedules of the sensor nodes to reduce the correlation among …

Three Essays On Real Estate Equities And Real Estate Investment Trusts, Fahad Almudhaf

Finance and Real Estate Dissertations - Archive

This dissertation consists of three distinct essays. The first essay provides initial empirical evidence on the usefulness of consumer confidence index and investor optimism index in predicting REIT price movements. I find evidence of uni-directional Granger causality from REIT returns to the change in Michigan consumer sentiment index for the period 1978 - 2008. I find a negative and statistically significant relationship between the level of Michigan consumer sentiment index in one month and the FTSE/NAREIT US REIT returns in the next one, six, and twelve months.

Alcott And The Terrible, Horrible, No Good, Very Bad Public Sphere: Identity, Privacy, And Publication In Louisa May Alcott's Little Women, Leslie Bukowski Jan 2010

Alcott And The Terrible, Horrible, No Good, Very Bad Public Sphere: Identity, Privacy, And Publication In Louisa May Alcott's Little Women, Leslie Bukowski

English Theses - Archive

An aspect of Louisa May Alcott's novel Little Women that has not been examined is the tension between the public and private spheres within the text. Since the text is semi-autobiographical in nature, issues of public and private occur throughout Little Women where the March family, initially represented within an enclosure of domesticity, move into the public sphere around them. This movement alters the prevailing public discourse before ushering in a second movement: the drawing members of the public sphere into domesticity, adding new influences into the home. By analyzing settings of the novel and the personal journals of the …

Borges And New Media: Connections Via Heterotopic Spaces, Sherrin Frances Jan 2010

Borges And New Media: Connections Via Heterotopic Spaces, Sherrin Frances

English Theses - Archive

Borges' short stories such as "The Aleph" and "The Garden of Forking Paths" were uncanny in their foreshadowing of hypertext and internet developments in the 1990's. His work was often credited as inspiration for various projects striving to make use of these "new" technologies in creative ways. These projects include, for example, Stuart Moulthrop's seminal Storyspace work, "Forking Paths," and a MyStory project called, "Borges Fetishization," based on Greg Ulmer's theories of Electracy. The connection between Borges' situations and web-based projects such as these can be further developed through an examination of heterotopic space. The heterotopias found in Borges' work …

The Effects Of Community Uninsurance On Health Care Quality For The Insured Population, Tuan Anh Nguyen Jan 2010

The Effects Of Community Uninsurance On Health Care Quality For The Insured Population, Tuan Anh Nguyen

Economics Theses - Archive

An important aspect of the ongoing health care reform of 2010 is to provide health coverage to the uninsured, the rising population of which has remained a significant challenge to overcome. Previously, efforts to reduce the number of people without health insurance have been centered on a moral rationale that providing care for the medically indigent was "the right thing" to do. However, recent evidence suggests that it might be in the best interest of people who are already insured to be concerned about the rate of uninsurance in their communities because of a potential negative spillover effect. Using four …

Re-Imagining African Christologies: Conversing With The Interpretations And Appropriations Of Jesus Christ In Contemporary African Christianity, Victor I. Ezigbo Jan 2010

Re-Imagining African Christologies: Conversing With The Interpretations And Appropriations Of Jesus Christ In Contemporary African Christianity, Victor I. Ezigbo

Faculty Books

"Who do you say that I am" (Mark 8:29) is the question of Christology. By asking this question, Jesus invites his followers to interpret him from within their own contexts-history, experience, and social location. Therefore, all responses to Jesus's invitation are contextual. But for too long, many theologians particularly in the West have continued to see Christology as a universal endeavor that is devoid of any contextual influences. This understanding of Christology undermines Jesus's expectations from us to imagine and appropriate him from within our own contexts. In Re-imagining African Christologies, Victor I. Ezigbo presents a constructive exposition of the …
