Making Room For One Another: Practicing Dynamic And Designed Dialogicality In A Kindergarten Classroom, Gerri August

Open Access Dissertations

The territory of this critical ethnography lies at the intersection of democratic, transformative pedagogy and differences that made a difference in an urban kindergarten. It is an interpretation of a democratic, transformative educator responding to sociocultural differences that emerged in the classroom discourse. Often, such differences lead to otherization. This study interprets the constraints and possibilities that encouraged students to recognize and respect difference. The kindergarten classroom is interpreted in the framework of activity theory. Drawing largely on discourse analysis, this interpretation turns on the interplay between two primary elements in the activity system. The first is Zeke, the kindergarten …

Petrogenesis And Eruption Dynamics At Hudson Volcano, Southern Chile, David Jon Kratzmann

Open Access Dissertations

Petrogenesis and eruption dynamics at Hudson volcano, southern Chile Hudson volcano is the southern-most volcano of the Chilean Southern Volcanic Zone. There have been at least twelve Holocene to Recent explosive eruptions, the most significant of which were the 6700 years before present (yrs BP), the 3600 yrs BP, and 1991 eruptions. Pre-eruptive storage of the trachyandesite from the 1991 eruption occurred at pressures of ∼1.5-3.0 km depth at 972°C (±26) under water-saturated conditions. Magmas from the 1991 eruption can be related through combined fractional crystallization and magma mixing. An ascending basaltic magma may have intersected the trachyandesitic storage region …

Simulating Widespread Tephra Dispersal From Explosive Volcanic Eruptions, Julie Ann Fero

Open Access Dissertations

The primary objective of this work was to characterize the main eruptive and atmospheric conditions responsible for the formation of widespread tephra deposits observed within the geologic record. To accomplish these objectives, the Lagrangian ash dispersal model Puff was initially used to simulate two historic eruptions, the 1980 eruption of Mt. St. Helens (MSH) and the 1991 eruption of Mt. Pinatubo. Two high-resolution atmospheric reanalysis datasets (ERA-40 and NCEP/NCAR-40) were used for the simulations allowing trajectory analysis up to altitudes of 50 km. Results from these Puff simulations were directly compared to visible, infrared, and ultraviolet satellite images taken during …

The Problem With Particularized Injury: The Disjuncture Between Broad-Based Environmental Harm And Standing Jurisprudence, Hope M. Babcock

Georgetown Law Faculty Publications and Other Works

Several recent events harmonically converged into the topic for this article. The first was a posting on Georgetown Law’s environmental law professors’ listserv by Professor John Bonine, which raised a number of questions about whether and how standing doctrine might be rethought in light of the Supreme Court’s opinion in Massachusetts v. EPA. That opinion relaxed the states’ standing burden because of the unique sovereign interests, finding that federalism bargaining earned states “special solicitude” when it came to meeting the Court’s standing requirements.

The second was a complaint filed by a consortium of regional environmental organizations, Chesapeake Bay Foundation, …

The Nature Of People's Perceptions Of Wolves, Laura Briana Nobel

Dissertations and Theses

European immigrants once regarded wolves as the "devil in disguise" (Lopez, 1978, p.40). With our growing awareness of other cultural perspectives and flourishing body of scientific knowledge with regard to wolves' behavior, our perceptions of wolves have become more complicated and nuanced. Our collective awareness of the environment in which we live also gathers complexity. I examine these issues in this study. Wolves are returning to Oregon. The arrival of wolf B-45 in 1999 heralded the beginning of the return of wild wolves to Oregon. More wolves are expected to cross the border as young sub-adults disperse from the growing …

The Influence Of Sparc On Collagen Deposition In Asbestos-Induced Pulmonary Fibrosis, Aubrey Meghan Smartt

Graduate Student Theses, Dissertations, & Professional Papers

Pulmonary fibrosis involves the invasion of lung tissue with fibrotic, scar tissue and affects roughly five million people total worldwide. Fibrotic development in the lung has several causes, including chronic inflammatory diseases, infections, medical compounds, and environmental agents. There is no known cure for the disease, but only therapies to improve quality of life. Scar tissue formation must be targeted in order to begin to provide any type of cure for fibrotic diseases. In this study, asbestos was used to induce pulmonary fibrosis in a mouse model and gene expression studies were then performed to identify potential candidate genes involved …

Materiality As The Basis For The Aesthetic Experience In Contemporary Art, Christina Murdoch Mills

Graduate Student Theses, Dissertations, & Professional Papers

A number of historical philosophical theories relate to materiality in contemporary art and the role of art objects as an extension of ontology, or the study of the nature of being. The Kantian idea of the “aesthetic experience” is the point of departure, tracing philosophical discourse of how art functions via its materiality through the writings of Ludwig Wittgenstein, Martin Heidegger, Jean-Paul Sartre and Jacques Maritain to the post-modern considerations of David Hickey and Arthur Danto. The research for this thesis focuses on how contemporary art, in all its various forms, functions via art’s material qualities or materiality. The objective …

The Distribution Of /S/ In Blackfoot: An Optimality Theory Account, Ryan Denzer-King

Graduate Student Theses, Dissertations, & Professional Papers

In this thesis I propose that the distribution of /s/ in Blackfoot can be explained by positing that /s/ is inherently moraic in Blackfoot, and explore this hypothesis via two proposals about moraic /s/. The first is that /s/ in complex onsets, e.g., stsiki, ‘another’, is extrasyllabic, and that a moraic /s/ reduces the markedness of these extrasyllabic segments. The second is that because /s/ is moraic, it can act as a syllable nucleus, which explains why the distribution of geminate /ss/ is more similar to long vowels than to geminate consonants. In Blackfoot, clusters of more than two consonants …

Water Use And Natural Limits In The Las Vegas Valley: A History Of The Southern Nevada Water Authority, Christian Harrison

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis examines the history of the Southern Nevada Water Authority (SNWA) and how it has helped transform various aspects of southern Nevada's economy and environment. Prior to the establishment of the SNWA in 1991 the Las Vegas Metropolitan Area (LVMA) possessed several competing water providers whose opposition to one another adversely affected the management of water in the region. These water providers recognized this problem, came together, and negotiated the creation of a regional water agency, the SNWA. This organization, comprised of representatives from each of the LVMA's water providers has the power to institute policy across municipal boundaries. …

Shuttle To Serenity: The History And Impact Of Zion National Park's Transportation System, Reuben Edward Wadsworth

UNLV Theses, Dissertations, Professional Papers, and Capstones

Shuttle to Serenity focuses on the history of the Zion National Park transportation system's planning, construction and implementation process. It details the unfavorable conditions in pre-shuttle Zion and shows how the shuttle has drastically improved the visitor experience and park environment since operations began in May 2000. The thesis also chronicles the groundbreaking partnership between Springdale, the gateway community, and Zion National Park, which proved vital in the shuttle implementation process. Ultimately, Shuttle to Serenity demonstrates that public transportation systems in national parks align the NPS with its mandate to preserve the natural beauty of each park for the enjoyment …

Results indicate that across groups of different types of gamblers, there are significant differences in perceptions toward the legalized casino gambling industry. Also, across groups of different types of gamblers, there are significant differences in attitudes toward legalized casino gambling. Additionally, there are significant differences between perceptions toward the legalized casino gambling industry, and attitudes toward the legalization of casino gambling. In general, non-gamblers are relatively more …

Processes Of Disposition Development In K--5 Teachers, Deborah A. Obara

UNLV Theses, Dissertations, Professional Papers, and Capstones

Educators concur that teacher competency requires more than teaching knowledge and skills; competency requires appropriate professional dispositions. The development of professional dispositions is an expected outcome of teacher education programs. Since 2002, program accreditation has been contingent on documentation that prospective teachers have met national standards for dispositions. The body of educational research on disposition assessment has been growing. Research on disposition learning and development, however, has been impeded by the prevailing conceptualization of dispositions as fixed traits resistant to change. The present study conceptualized dispositions as malleable constructs within a theoretical framework that synthesized a cognitive model of thinking …

Effects Of Similarity Metrics On Document Clustering, Rushikesh Veni

UNLV Theses, Dissertations, Professional Papers, and Capstones

Document clustering or unsupervised document classification is an automated process of grouping documents with similar content. A typical technique uses a similarity function to compare documents. In the literature, many similarity functions such as dot product or cosine measures are proposed for the comparison operator.

For the thesis, we evaluate the effects a similarity function may have on clustering. We start by representing a document and a query, both as a vector of high-dimensional space corresponding to the keywords followed by using an appropriate distance measure in k-means to compute similarity between the document vector and the query vector to …

Ground Reaction Forces For Children Running In Different Shoes, Dana Forrest

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to determine whether certain ground reaction force parameters such as impact force (F1), second maximum force (F2), loading rate, stance time and average vertical ground reaction force (Fzavg) differ when 11-13 year old children run in a neutral shoe (Nike Air Pegasus+ 25) that is either a child or adult style.

Shoes were impact tested in an impact test instrument to determine any performance differences between the two shoes. Next, 10 healthy female subjects aged 12.03 ± 1.14 years with a height of 154.6 ± 4.90 cm and a mass of 46.18 ± 14.33 …

This study tested the effectiveness of interactive teaching methods on the learning of wetland ecology concepts by 6 th grade science students. 330 students from nineteen different 6 th grade science classes were used in this study. These classes were separated into four different treatment groups, each containing presentations with varying degrees of student interaction. This was done in attempt to test the effect of interactive teaching methods on attitude about the environment and knowledge regarding wetland ecology concepts, specifically, on outdoor education as a process of learning by doing. Student knowledge of wetland ecology concepts and attitudes toward the …

When Did The Ancestors Of Polynesia Begin To Migrate To Polynesia? The Mtdna Evidence, David Lesniewski

UNLV Theses, Dissertations, Professional Papers, and Capstones

The timing and nature of the migration of the ancestors of the Polynesian people is debated by two competing theories. The "Express Train" and "Slow Boat" theories assert that the migration of the Proto-Polynesian people began around 6,000 years before present (BP) or around 10,000 years BP respectively. Through the use of haplogroups and specific genetic mutations a direct relationship between the Proto-Polynesians and modern Polynesians was attempted to test which of these theories was correct. The ancient skeletal remains from the island of Borneo currently housed at UNLV were used in this study as their dates fall within both …

Integrated Responses Of Crustaceans Inhabiting Estuaries To The Challenges Of Feeding And Digestion In Low Salinity, Daniel Luke Curtis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Estuaries are highly productive and serve as vital habitats for numerous decapod crustacean species. However, the environmental conditions within estuaries are often highly dynamic and subject to large changes in salinity and temperature that occur on seasonal and tidal scales. Not all of the species occupying these habitats are adept in coping with changes in these environmental conditions. This dissertation describes the influence of low salinity conditions on the 1) habitat preference, 2) feeding behaviour and 3) digestive physiology of crustaceans inhabiting estuaries. I have primarily focussed on a weak osmoregulator, the Dungeness crab, Cancer magister , but have also …

Gods R Us, Alivelu Nagamani

UNLV Theses, Dissertations, Professional Papers, and Capstones

Around Grecian orchards. On Trojan battlefields. In Siva's realm. Inside Hanuman's heart. Of gods, demons, and others who love us, hate us, serve us, interfere with us. Of humans larger than life. When gods were not in hiding. About a space not reached via explanations. Poems in Gods R Us come from Greek/Roman and Indic myths, they retell myths, comment on myths, and refer to myths - they could not have been without myths. Distillation and attentiveness create the time needed to be one in the spirit of the poem. I range from reverential to playful.

Mining Wars: Corporate Expansion And Labor Violence In The Western Desert, 1876-1920, Kenneth Dale Underwood

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation analyzes the class struggle in the late nineteenth and early twentieth centuries in Mexico and the western United States to illuminate the social transformation taking place in this trans-national region. The US and Mexico both underwent a significant metamorphosis in this era. The creation of a labor based working class and the displacement of occupational professionals from the upper class in many communities into an emerging middle class disrupted traditional social structures in both nations. This systematic social change, occurring nearly simultaneously in the US and Mexico, was complicated by the emerging system of monopoly capitalism, which led …

Oxidation Modeling By Means Of Molecular Dynamics, Chaiyod Soontrapa

UNLV Theses, Dissertations, Professional Papers, and Capstones

Oxidation modeling is normally engineered to study systems at macroscopic scales, mostly in analytical forms based on diffusion theories. The associated time scale is usually in months, days, or minutes, and the length scale is in the order of microns. In this dissertation, oxidation modeling is performed at atomistic scale with the time and length scales in picoseconds and angstroms, respectively, using molecular dynamics. Molecular dynamics simulations generate trajectories of each atom or particle in a system according to the laws of physics. Studying oxidations under the atomistic point of view can offer new insights on atomic behaviors and influencing …

The Efficacy Of Fragrance Use For Enhancing The Slot Machine Gaming Experience Of Casino Patrons, Gael D. Hancock

UNLV Theses, Dissertations, Professional Papers, and Capstones

Once guests are inside a casino, experiential factors within the casino must be managed so that these guests are encouraged to engage in the gaming opportunities; remain in the casino to eat and shop; return to the casino; and hopefully, to recommend the casino to others. Ambient conditions have been shown to influence a person's willingness to stay in a public setting and their repatronage intentions. Air fragrance is one small, but controllable piece of the experience puzzle that includes décor, lighting, music and other ambient sounds, comfort of the seating, quality of the service, perception of cleanliness and ease …

Analysis Of Flaked Stone Lithics From Virgin Anasazi Sites Near Mt. Trumbull, Arizona Strip, Cheryl Marie Martin

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis examines flaked stone tools that were used by the Virgin Anasazi and the debitage resulting from their manufacture at six sites in the Mt. Trumbull region in order to infer past human behavior. The behaviors being examined include activities carried out at sites, the processing and use of raw stone materials, and patterns of regional exchange. I have applied obsidian sourcing technology and an analysis of flaked stone attributes. The research indicates a range of activities occurred at habitation sites at Mt. Trumbull, and toolmakers did not need to expend large amounts of time and energy on acquiring …

Exploring The Effects Of Online Instruction On Reading Comprehension Achievement Of Students With Learning Disabilities, Nancy Shuman Fitzgerald

UNLV Theses, Dissertations, Professional Papers, and Capstones

Two major pieces of legislation, the Individuals with Disabilities Education Act (2004) and No Child Left Behind (NCLB) (2001) mandate that students with disabilities be placed in the Least Restrictive Environment and have access to the general education curriculum. To provide access to the general education curriculum, inclusion in general education classes for students with disabilities has become the accepted practice. Many students with specific learning disabilities experience difficulties with the general education curriculum because their reading ability falls significantly below the school curriculum and textbook instructional levels (Deshler & Schumaker, 1993). The Word Identification Strategy (Lenz, Schumaker, Deshler, & …

Molecular Systematics And Phylogeography Of The Genus Richardsonius, Derek Dee Houston

UNLV Theses, Dissertations, Professional Papers, and Capstones

The complex geological and climatic events that significantly altered the landscape throughout the Cenozoic Era impacted the diversification of many North American taxa, including freshwater fishes. Here, I employ an array of phylogenetic analyses using a multiple gene tree approach to address several questions regarding the phylogenetic relationships of the North American cyprinid genus Richardsonius and two other closely related genera, Clinostomus and Iotichthys. I also use divergence time estimates generated using fossil calibrations to qualitatively assess the phylogeographic implications of evolution within and among these three genera. Mitochondrial and nuclear DNA sequences show a sister relationship between Iotichthys and …

Dancing In The Ashes, Vytautas Adolph Malesh

UNLV Theses, Dissertations, Professional Papers, and Capstones

The following novel is the third draft of my creative thesis entitled Dancing in the Ashes . It is an exploration of the Detroit rave scene in its dying days, and it mixes real and imagined places and events in order to portray the essence of that time, if not the factuality. The bulk of the novel follows just over two weeks in the life of Thomas Kowalski, a drug dealer living with his parents in suburban Detroit. He parties constantly and seldom works except as necessary to keep his job at a local record store - an invaluable source …

Eminent Domain: The Unintended Consequences Of Kelo, Tracy Lynn Bower

UNLV Theses, Dissertations, Professional Papers, and Capstones

In recent years, local governments in the United States have increasingly used eminent domain to promote economic development, raising concerns among property-right advocates over what those advocates view as unlawful, or what should be unlawful, takings of private property in order to benefit another private property owner. This philosophical and legal dispute reached a crisis point in the 2005 United States Supreme Court decision in Kelo v. City of New London. In that decision, the court narrowly upheld a Connecticut Supreme Court ruling granting the City of New London permission to redevelop land that had been seized from existing homeowners …

Protection Of Macrophages J774a.1 By Purine Nucleoside Analogues From Bacillus Anthracis Mediated Necrosis, Zadkiel R. Alvarez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Eight years after the lamentable anthrax attacks, major scientific effort continues to be done, in order to stop imminent acts of bioterrorism. Innovative ways of therapy against the anthrax disease are being investigated. B. anthracis, the etiological agent of the infection, has a dormant stage in its life cycle known as the endospore. When conditions become favorable spores germinate, transforming into vegetative bacteria. In inhalational anthrax, the most fatal manifestation of the disease, spores enter the organism through the respiratory track, and are phagocytosized by alveolar macrophages of the lungs. Spores are able to sense nutrient availability, activating their germination …
