Federalism and Civil Conflict: the Missing Link?

Federalism and Civil Conflict: the Missing Link?

Date: August 2012
Creator: Lancaster, Ross
Description: This thesis investigates federalism and civil conflict. Past work linking federalism and civil conflict has investigated the factors that pacify or aggravate conflict, but most such studies have examined the effect of decentralization on conflict onset, as opposed to the form federalism takes (such as congruent vs incongruent forms, for example). I collect data on civil conflict, the institutional characteristics of federalist states and fiscal decentralization. My theoretical expectations are that federations who treat federal subjects differently than others, most commonly in an ethnically based manner, are likely to experience greater levels of conflict incidence and more severe conflict. I find support for these expectations, suggesting more ethnically based federations are a detriment to peace preservation. I close with case studies that outline three different paths federations have taken with regards to their federal subunits.

Female Orgasm From Intercourse:  Importance, Partner Characteristics, and Health

Female Orgasm From Intercourse: Importance, Partner Characteristics, and Health

Date: August 2012
Creator: Powers, Catherine R.
Description: Previous research indicates that women prefer orgasms triggered by penile-vaginal intercourse (PVI) as compared to those triggered by direct manual stimulation of the clitoris. However, for reasons that are not well understood, most women are unable to reach PVI orgasms as often as they desire. In addition, it is unclear why many women prefer PVI orgasms to those triggered by direct clitoral stimulation. This study developed a more precise measure of PVI orgasm frequency and evaluated key predictors of this frequency, including duration of intercourse, physical and psychological health, and partner traits with implications for either mating quality or relationship quality. The present study also measured PVI orgasm importance and investigated why it is important for many women. The sample consisted of 835 adult women with experience in PVI. Mean PVI orgasm frequency was 50%, with 39.4% of women never or rarely having PVI orgasms, 37.1% sometimes having PVI orgasms, and 23.5% almost always or always having PVI orgasms. As a median response, women believed that PVI orgasm was “very important” and perceived importance was correlated with orgasm frequency (r = .31, p < .001), as were reasons for importance. Duration of intercourse showed a linear relationship with PVI orgasm ...

First Principles Calculations of the Site Substitution Behavior in Gamma Prime Phase in Nickel Based Superalloys

First Principles Calculations of the Site Substitution Behavior in Gamma Prime Phase in Nickel Based Superalloys

Date: August 2012
Creator: Chaudhari, Mrunalkumar
Description: Nickel based superalloys have superior high temperature mechanical strength, corrosion and creep resistance in harsh environments and found applications in the hot sections as turbine blades and turbine discs in jet engines and gas generator turbines in the aerospace and energy industries. The efficiency of these turbine engines depends on the turbine inlet temperature, which is determined by the high temperature strength and behavior of these superalloys. The microstructure of nickel based superalloys usually contains coherently precipitated gamma prime (?) Ni3Al phase within the random solid solution of the gamma () matrix, with the ? phase being the strengthening phase of the superalloys. How the alloying elements partition into the and ? phases and especially in the site occupancy behaviors in the strengthening ? phases play a critical role in their high temperature mechanical behaviors. The goal of this dissertation is to study the site substitution behavior of the major alloying elements including Cr, Co and Ti through first principles based calculations. Site substitution energies have been calculated using the anti-site formation, the standard defect formation formalism, and the vacancy formation based formalism. Elements such as Cr and Ti were found to show strong preference for Al sublattice, whereas Co ...

From Ritual to Art in the Puritan Music of Colonial New England: the Anthems of William Billings

From Ritual to Art in the Puritan Music of Colonial New England: the Anthems of William Billings

Date: August 2012
Creator: Dill, Patrick W.
Description: The manner in which Billings’s music contrasts with the Puritan musical ideal clearly demonstrates his role in the transition from ritual to art in the music of eighteenth-century New England. The tenets of Puritan worship included the restriction that music should serve primarily as a form of communal prayer for the congregation and in a secondary capacity to assist in biblical instruction. Billings’s stylistic independence from Puritan orthodoxy began with a differing ideology concerning the purpose of music: whereas Calvin believed music merely provided a means for the communal deliverance of biblical text, Billings recognized music for its inherent aesthetic worth. Billings’s shift away from the Puritan musical heritage occurred simultaneously with considerable change in New England in the last three decades of the eighteenth century. A number of Billings’s works depict the events of the Revolutionary War, frequently adapting scriptural texts for nationalistic purposes. The composition of occasional works to commemorate religious and civic events reflects both the increase in society’s approval of choral music beyond its nominal use in worship, both in singing schools and in choirs. With his newfound independence from Puritan ritual, Billings seems to have declared himself one of the United States of America’s first ...

Geography of Hiv Infection Among Adults Aged 50 Years and Older in Texas From 1999-2009

Geography of Hiv Infection Among Adults Aged 50 Years and Older in Texas From 1999-2009

Date: August 2012
Creator: Hedrich, Mara Nicole
Description: Twenty four percent of all HIV infections in the United States occur among adults aged 50 and older (mature adults), yet little is understood of the dynamics of HIV infection among this group in Texas. Data from 1999 to 2009 examined the relationship between HIV spatial and temporal patterns affecting socio-economic and demographic variables including poverty, gender, race/ethnicity and mode of exposure. Results revealed highest HIV infection rates among White homosexual men, Black males engaged in IV-drug use, Black female heterosexuals and minorities in poverty. Concentrations of HIV infection among mature adults were located primarily in urban centers of Houston and Dallas and indicated increasing HIV infection rates from 1999 to 2009. These results will assist future allocation of resources by zip code in urban areas for this understudied population.

Goethe Settings By Johann Friedrich Reichardt and Carl Friedrich Zelter: Text, Music and Performance Possibilities

Goethe Settings By Johann Friedrich Reichardt and Carl Friedrich Zelter: Text, Music and Performance Possibilities

Date: August 2012
Creator: Moore, Wes C.
Description: The connection between text, music, and performance in the lieder of the late eighteenth and early nineteenth centuries is an integral aspect to fully comprehending the style and performance of the genre. It is also essential in order to understand the full development of the lied in its totality. The era represented a transitional period in musical development, influenced by Enlightenment values of elegance, good taste, simplicity, and naturalness which sought to eradicate the overly decorative “excesses” of the high-Baroque. In this study, emphasis is placed upon the unique development of the lied in the northern German regions by the composers Johann Friedrich Reichardt and Carl Friedrich Zelter and their musical settings of the lyric poetry of Johann Wolfgang von Goethe. The study also addresses the overall development of the genre as it progressed from the Baroque through Classicism/Neo-Classicism, Sturm und Drang, and into Romanticism exploring the musical settings and performance possibilities both then and now in the context of the various treatises and correspondence between the composers and poet. It seeks to effectively address the notion that these early songs were composed and performed by those versed in the ideal of music being an improvisatory/dramatic vehicle for expressing emotion ...

Harmony Or Discord: Disordered Eating and Personality Traits of College Music Majors

Harmony Or Discord: Disordered Eating and Personality Traits of College Music Majors

Date: August 2012
Creator: DiPasquale, Laura D.
Description: Personality traits, such as neuroticism, perfectionism, and a narrow self-concept have been identified as risk factors for eating disorders or have been found at higher rates in those with eating disorders (e.g., Brannan & Petrie, 2008; Cash & Deagle, 1997; Cervera et al., 2003). Musicians exhibit many of these personality traits associated with eating disorders (e.g., Kemp, 1981), however eating disorder prevalence has not been studied in musicians. The present study examined the prevalence of eating disorders and pathogenic weight control behaviors among college music majors. This study also compared personality traits (i.e., neuroticism, perfectionism, musician identity) between music majors and nonmajors and examined which personality traits best predicted bulimic symptomatology. Participants were 93 female and 126 male undergraduate students majoring in music and a nonmusician comparison group of 310 women 140 men from the same university. Music majors and nonmajors did not differ from each other with regards to eating disorder prevalence rates. Exercising and fasting/strict dieting were the primary means of weight control amongst all participants. With regards to personality traits, female and male music majors reported higher levels of perfectionism than their nonmajor counterparts and male music majors reported higher levels of neuroticism than male nonmajors. After ...

Higher Education and Native Nation Building: Using a Human Capital Framework to Explore the Role of Postsecondary Education in Tribal Economic Development

Higher Education and Native Nation Building: Using a Human Capital Framework to Explore the Role of Postsecondary Education in Tribal Economic Development

Date: August 2012
Creator: Marling, David
Description: Native American Nations have perpetually had the highest rates of poverty and unemployment and the lowest per capita income of any ethnic population in the United States. Additionally, American Indian students have the highest high school dropout rates and lowest academic performance rates as well as the lowest college admission and retention rates in the nation. As Native Nations try to reverse these trends through sustainable economic development, they must do so with a limited number of educated, skilled workers in their own communities and with a complicated relationship with higher education that obstructs their ability to create a viable work force. This qualitative study proposed to research American Indian postsecondary access within the context of Native nations’ sovereignty and their social and economic development. Utilizing a theoretical framework of human capital and its role in rebuilding Native American economies, interviews were conducted with 19 education informants representing federally-recognized tribes in the Southern Plains Region. Major themes included financial issues related to college going in Native populations, familial and community influences, academic readiness, curricular development and delivery, the role of higher education in preparing students for tribal employment, and tribal economic development. Increasing Native American college student success and preparation ...

Hochschild Cohomology and Complex Reflection Groups

Hochschild Cohomology and Complex Reflection Groups

Date: August 2012
Creator: Foster-Greenwood, Briana A.
Description: A concrete description of Hochschild cohomology is the first step toward exploring associative deformations of algebras. In this dissertation, deformation theory, geometry, combinatorics, invariant theory, representation theory, and homological algebra merge in an investigation of Hochschild cohomology of skew group algebras arising from complex reflection groups. Given a linear action of a finite group on a finite dimensional vector space, the skew group algebra under consideration is the semi-direct product of the group with a polynomial ring on the vector space. Each representation of a group defines a different skew group algebra, which may have its own interesting deformations. In this work, we explicitly describe all graded Hecke algebras arising as deformations of the skew group algebra of any finite group acting by the regular representation. We then focus on rank two exceptional complex reflection groups acting by any irreducible representation. We consider in-depth the reflection representation and a nonfaithful rotation representation. Alongside our study of cohomology for the rotation representation, we develop techniques valid for arbitrary finite groups acting by a representation with a central kernel. Additionally, we consider combinatorial questions about reflection length and codimension orderings on complex reflection groups. We give algorithms using character theory to compute ...

Homeland Security Roles and Responsibilities: an Examination of Texas Police Chiefs’ Perceptions

Homeland Security Roles and Responsibilities: an Examination of Texas Police Chiefs’ Perceptions

Date: August 2012
Creator: Thimamontri, Apinya
Description: Research has shown that the police industry has entered into an era of homeland security. However, whether the core functions of policing have significantly changed since September 11, 2001, has been the topic of considerable debate. Using secondary data, the research identifies variables that are most influential in predicting whether Texas police chiefs understand their departments’ homeland security roles and responsibilities. The data was originally obtained in 2007 through self-administered surveys of police chiefs attending the Texas Chief Leadership Series (TPCLS) and the New Chief Development Program (NCDP).
