Description
The relationship between biodiversity and ecosystem functioning (BEF) is a central issue in ecology, and a number of recent field experimental studies have greatly improved our understanding of this relationship. Spatial heterogeneity is a ubiquitous characterization of ecosystem processes, and has played a significant role in shaping BEF relationships. The first step towards understanding the effects of spatial heterogeneity on the BEF relationships is to quantify spatial heterogeneity characteristics of key variables of biodiversity and ecosystem functioning, and identify the spatial relationships among these variables. The goal of our research was to address the following research questions based on data collected in 2005 (corresponding to the year when the initial site background information was conducted) and in 2008 (corresponding to the year when removal treatments were conducted) from the Inner Mongolia Grassland Removal Experiment (IMGRE) located in northern China: 1) What are the spatial patterns of soil nutrients, plant biodiversity, and aboveground biomass in a natural grassland community of Inner Mongolia, China? How are they related spatially? and 2) How do removal treatments affect the spatial patterns of soil nutrients, plant biodiversity, and aboveground biomass? Is there any change for their spatial correlations after removal treatments? Our results showed that variables of biodiversity and ecosystem functioning in the natural grassland community would present different spatial patterns, and they would be spatially correlated to each other closely. Removal treatments had a significant effect on spatial structures and spatial correlations of variables, compared to those prior to the removal treatments. The differences in spatial pattern of plant and soil variables and their correlations before and after the biodiversity manipulation may not imply that the results from BEF experiments like IMGRE are invalid. However, they do suggest that the possible effects of spatial heterogeneity on the BEF relationships should be critically evaluated in future studies.

Description
The most horrific, darkest, and powerful forms of the sublime take place inside the enclosure of the human psyche; the interior of the mind is the playground for the sublime--not the crag and canyon filled natural world. For Immanuel Kant and Edmund Burke, the driving force of the power of the sublime stems from the feelings of pain and fear: where is that more manifested than in the mind? Unlike the common, traditional, and overwhelmed discussion of Percy Shelley and his contemporaries and the power of the sublime in nature, I will argue that in The Cenci, Shelley, through well-chosen diction and precise composition of terrifying images, fashions characters and scenes in an emotion-driven play that elevates the mind of the reader to a transcendent sublime experience. Through a discussion of the theories of the aesthetic of the sublime laid out by Longinus, Burke, and Kant, I will provide a foundation for the later discussion of the rhetorical sublime evoked by Shelley in the ardent and horrifying play that is The Cenci. Looking at the conventional application of the theories of the sublime to romantic writing will make evident the holes in the discussion of the sublime and romantic writings that have almost forgotten the powerful and psychological rhetorical aspect of the sublime that is emphasized in the theoretical writings of both Burke and Kant. To clarify what is traditionally associated with Shelley and the sublime, a brief analysis of the Shelleyean sublime and Shelley's 1816 poem "Mont Blanc" will prepare the reader for an unconventional, but every bit important and powerful, function of the sublime in the 1819 play The Cenci based on the horrific happenings of a historical 16th century Italian noble family.

Description
This study utilized symbolic interaction as a framework to examine the impact of mobility on four veteran elementary general music teachers' identities, roles, and perceptions of role support. Previous research has focused on teacher identity formation among preservice and novice teachers; veteran teachers are less frequently represented in the literature. Teacher mobility research has focused on student achievement, teachers' reasons for moving, and teacher attrition. The impact of mobility on veteran teachers' identities, roles, and perceptions of role support has yet to be considered. A multiple case design was employed for this study. The criteria for purposeful selection of the participants were elementary general music teachers who had taught for at least ten years, who had changed teaching contracts and taught in at least two different schools, and who were viewed as effective music educators by fine arts coordinators. Data were collected over a period of eight months through semi-structured interviews, email correspondence, observations, review of videotapes of the participants' teaching in previous schools, and collection of artifacts. Data were analyzed within and across cases. The cross-case analysis revealed themes within the categories of identity, role, and role support for the participants. The findings suggest that the participants perceived their music teacher roles as multi-dimensional. They claimed their core identities remained stable over time; however, shifts in teacher identity occurred throughout their years as teachers. The participants asserted that mobility at the start of their careers had a positive impact because they each were challenged to solidify their own teacher identities and music teacher roles in varied school contexts. Mobility negatively impacted role and teacher practices during times when the participants adjusted to new school climates and role expectations. Role support varied depending upon school context, and the participants discovered active involvement in the school community was an effective means of seeking and acquiring role support. Reflection experiences in music teacher preparation programs, as well as mentoring and professional development geared toward teacher identity formation and role maturation, may assist teachers in matching their desired school context with their teacher identities and perceptions of the music teacher role.

Description
In this study, I examined how African American students in a church youth group constructed ethnic and spiritual identities as they engaged with community literacy practices. Arizona's small, scattered population of African Americans is reflected within participants' multi-ethnic schools where they describe feelings of being almost invisible to school agents and peers. Listening to students, I came to deeply understand how they struggled with cultural isolation and racial discrimination. The growing tensions with state immigration reform only magnified those feelings as participants perceived the ban on ethnic studies to be another attempt to exclude them from school curriculums. By using utilizing four identity types, I gained greater insights into participants' negotiation of ethnicity and spirituality. Drawing from critical race theory, I utilized counter-storytelling to not only recapture participants' experiences with social injustice, but also to illustrate how the youth group empowers the students to become activists. Resisting the paralyzing effects of racial stereotypes, participants emerged as essayists, artists, orators, and spoken word poets.

Description
Worldwide, riverine floodplains are among the most endangered landscapes. In response to anthropogenic impacts, riverine restoration projects are considerably increasing. However, there is a paucity of information on how riparian rehabilitation activities impact non-avian wildlife communities. I evaluated herpetofauna abundance, species richness, diversity (i.e., Shannon and Simpson indices), species-specific responses, and riparian microhabitat characteristics along three reaches (i.e., wildland, urban rehabilitated, and urban disturbed) of the Salt River, Arizona. The surrounding uplands of the two urbanized reaches were dominated by the built environment (i.e., Phoenix metropolitan area). I predicted that greater diversity of microhabitat and lower urbanization would promote herpetofauna abundance, richness, and diversity. In 2010, at each reach, I performed herpetofauna visual surveys five times along eight transects (n=24) spanning the riparian zone. I quantified twenty one microhabitat characteristics such as ground substrate, vegetative cover, woody debris, tree stem density, and plant species richness along each transect. Herpetofauna species richness was the greatest along the wildland reach, and the lowest along the urban disturbed reach. The wildland reach had the greatest diversity indices, and diversity indices of the two urban reaches were similar. Abundance of herpetofauna was approximately six times lower along the urban disturbed reach compared to the two other reaches, which had similar abundances. Principal Component Analysis (PCA) reduced microhabitat variables to five factors, and significant differences among reaches were detected. Vegetation structure complexity, vegetation species richness, as well as densities of Prosopis (mesquite), Salix (willow), Populus (cottonwood), and animal burrows had a positive correlation with at least one of the three herpetofauna community parameter quantified (i.e., herpetofauna abundance, species richness, and diversity indices), and had a positive correlation with at least one herpetofauna species. Overall, rehabilitation activities positively influenced herpetofauna abundance and species richness, whereas urbanization negatively influenced herpetofauna diversity indices. Based on herpetofauna/microhabitat correlations established, I developed recommendations regarding microhabitat features that should be created in order to promote herpetofauna when rehabilitating degraded riparian systems. Recommendations are to plant vegetation of different growth habit, provide woody debris, plant Populus, Salix, and Prosopis of various ages and sizes, and to promote small mammal abundance.

Description
In the first thirty years of the XX century, an old literary visual tradition was reborn in a series of new striking visual texts better known as calligrams. They were produced by some avant-garde poets such as Vicente Huidobro, José Juan Tablada, Alberto Hidalgo and Carlos Oquendo de Amat in Latin America, and Juan Larrea, Guillermo de Torre, Francisco Vighi, Luis Mosquera, and others in Spain. However, with few exceptions, the interpretation of those written drawings has caught little attention from literary critics. This research, contrasted to that of Willard Bohn's, is a contribution to the deciphering of such literary art form, designated here as the figurative visual poem. It is a proposal for its visual reading which draws from the fact that this type of text is concretely a drawing formed by written verses. As such, it can be regarded as a plastic writing, combining pictorial and verbal signs in one perceptible configuration on the page. The result of this semiotic operation is a hybrid product in which the iconic forms become symbolic and vice versa. It is in fact, an art object which should be approached as a text that can be seen as well as read. The study leads to the conclusion that Willard Bohn misreads the order in which language and image are articulated in the visual poem identified with the second order semiological system proposed by Roland Barthes, placing preeminence on language over image. This results in reading the avant-garde visual figurative poem in an ekphrastic fashion. Consequently, the role of the image in the system is left in an ambiguous realm at the time of deciphering this hybrid text. Our contribution to re-conducting this undertaking has been equally drawn from a semiotic stance taken from Louis Hjemslev that balances language and image as correlates of a semiotic function. Due to the signaling nature of both, language and figure, a visual poem becomes an iconic metaphor as well as a metaphoric icon, and moreover a self-referential sign, thus justifying its status of an autonomous art.

Description
The hagiographic comedy written by Tirso de Molina Los lagos de San Vicente (1607) presents the journey of Santa Casilda in search of the cure of an illness in her blood that affects her. Casilda rejects the medical assistance offered to her by Muslim doctors and miraculously she finds the cure in the Christian world. In this quest, the intellectual and theological evolution of the future saint in defense of the Christian faith is presented. This dissertation will study the resources that Tirso de Molina employs to show the rejection and displacement against the Islamic world represented by a series of erotic behaviors that, in the effort of dramatizing these impertinences they are characterized within a second discourse. Tirso de Molina takes advantage of the hagiographic comedy's discourse nature and the baroque's obscure literary characteristics to express his messages. This dissertation will study in detail how the combination of hagiographic theatrical elements with linguistic expressions are used to convey a subversive discourse that therefore suggests the application of queer theory as a frame of reference. As a result of this investigation it is concluded that Tirso de Molina promotes the hagiographic model and in order to contrast the triumph of the moral Catholic world over the immoral Muslim world the play writer makes references to the nefarious sin.

Description
ABSTRACT As referenced in Navajo ceremonial prayers and songs, "Saad bee hahoozhood jini," it began harmoniously with language. This dissertation examines and celebrates in new ways the meaning of language in Navajo literature. The first chapter is an introduction of this dissertation. I share my personal experiences with language, both English and Navajo, and how it has shaped me to be the person I am today as a Navajo speaker, student, educator, and professional. The second chapter contains an analysis and review of Western ideology of feminism and its place in Navajo society and a comparative study of several works written by Navajo authors, including Laura Tohe, Luci Tapahonso, and Nia Francisco, and how their creative works reflect the foundation of Navajo culture, Asdzaa Nadleehe, Changing Woman. The third chapter presents my own short fiction of Navajo characters living in today's society, a society that entails both positive and negative issues of Navajo life. These stories present realistic twenty-first century environments on the Navajo reservation. The fourth chapter consists of a short fiction written originally in the Navajo language. The story also represents the celebration of Navajo language as it thrives in today's time of tribal and cultural struggles. The sense of it being told in Navajo celebrates and preserves Navajo culture and language. The final chapter is the beginning of an oral narrative presented in written form, that of my grandmother's life story. This introduction of her story also is in itself a commemoration of language, oral Navajo language.

Description
Research has shown that being a female athlete in a male-dominated sports world is an oppressive burden, yet the experiences of being a black female athlete have been largely ignored. To combat this lack of attention, this paper invokes communication and feminist theorist Bell Hook's concept of moving black women from margin to center to reveal the intersectional oppression of gender and racial narratives that they face in sports. By outlining the difference between white and black femininity and studying media portrayals of popular black female athletes such as Venus and Serena Williams and others, it becomes obvious how black women are typecast into certain social and athletic roles. This research also includes an auto-ethnographic component of my own experience as a black female lacrosse player at the NCAA Division I level. This component functions as a point of comparison and contrast of the ideas and concepts I discuss. Lastly, I offer recommendations and suggestions as to how to empower young black female athletes and retain them in a variety of sports. The goal of my thesis is to place special attention onto black women in an area which there is an extreme lack of representation. My own empirical research has led me to the conclusion that not only is such a discussion important, but it is absolutely necessary. If we are to fight back against hegemonic social structures such as racism and gender roles in the sports world, we must first understand what we are up against. My thesis gives us a glimpse into our imposing opponents, and I hope that future research continues this trend so that black female athletes like myself may one day be considered an athlete in the same sense that our white peers are.

Description
For my project, I delve into the relationships of Victor and the Monster as well as the relationships Victor shares with other characters that were underdeveloped within the original novel by Mary Shelley in the novel Franeknstein. I examine their relationships in two components. The first through my own interpretation of Victor and the Monster’s relationship within a creative writing piece that extends the novel as if Victor had lived rather than died in the arctic in order to explore the possibilities of a more complex set of relationships between Victor and the Monster than simply creator-creation. My writing focuses on the development of their relationship once all they have left is each other. The second part of my project focuses on an analytical component. I analyze and cite the reasoning for my creative take on Victor and the Monster as well as their relationship within the novel and Mary Shelley’s intentions.
