Die Deutschen Enwanderer In Sacramento: German Immigrants In Sacramento, 1850--1859, Carole Cosgrove Terry Jan 2000

Die Deutschen Enwanderer In Sacramento: German Immigrants In Sacramento, 1850--1859, Carole Cosgrove Terry

UNLV Retrospective Theses & Dissertations

The economic and political conditions in Europe pushed German immigrants from their homelands, while the gold rush in California pulled them with dreams of riches. Some came directly from Germany, some made an intermediate stop in the United States, but, after arriving in California, many went to Sacramento. A small nucleus of permanent residents created an ethnic community where they practiced the German tradition of Vereinswesen, supported each other economically through loans and ready employment and, led by their Turnverein, continued practicing their customs and rituals emphasizing frivolity and celebration as they had in the "fatherland." Rather than assimilate, they …

The Rise And Fall Of A Wall And A Dialect: Observations Of Shifting Linguistic Behavior Among Former East Berliners, Anja Vogel

UNLV Retrospective Theses & Dissertations

After the dividing wall between East and West Berlin fell in 1989 many changes occurred on what was formerly the eastern side of the city. Polls taken soon after found out that the East Berliners' excitement about the reunification vanished quickly. One of the more prominent---but largely ignored---new problems was the linguistic barrier that had developed between East and West during the forty years of separation; The people in and around Berlin speak a regional dialect, Berlinish. Unbeknownst to most Berliners, the dialect took on a vastly different symbolic meaning for the people in the West than it did for …

Gospel Of The Heavenly Mother, Jennilyn F Hass Jan 2000

Gospel Of The Heavenly Mother, Jennilyn F Hass

UNLV Retrospective Theses & Dissertations

A collection of poems, Gospel of the Heavenly Mother asks, and attempts to answer, questions regarding the freedom that is available to the individual within a power structure. The two structures examined in the book are the grammar of the English language and organized religion, specifically the Church of Jesus Christ of Latter-day Saints. The poems enact the belief that as we reorient ourselves to these structures, freedom is possible; by usurping the syntax in which we communicate (and therefore the language by which we understand God and our relationship to Him/Her), we gain the ability to speak more fully …

The Seer's Abacus, Sasha Megan Steensen Jan 2000

The Seer's Abacus, Sasha Megan Steensen

UNLV Retrospective Theses & Dissertations

Negative Capability is the capacity to subtract the self so that there is room to add the other. Simone Weil, John Keats, Jack Spicer and Emily Dickinson suggest that the poet ought to renounce the self so as to offer up her own voice as a sacrifice to the world. The poet who hopes to speak for others must become no Body so that she can become every Body---she must subtract so that she can add. Weil insists that in order to annihilate the self, one must pay close attention to something other than her own ego. The poet must …

On The Come: A Novel, David Smith Stevens

UNLV Retrospective Theses & Dissertations

A creative, book-length work of fiction written at the end of the 20 th Century, this dissertation invariably converses in narrative concerns common to contemporary fiction, such as character point of view, plot and theme; however, in a narrower focus, specific issues of story and story telling and their relations to personal identity are examined through the maturation of a protagonist. As members of any society, we witness events common to a percentage of the whole but the meaning assigned to the common event may vary for each individual. For example, an automobile accident is a single event; however, every …

A High-Performance Liquid Chromatography System With Fenton's Reagent For Detection Of Gas-Phase Hydrogen Peroxide, Jun Liu Jan 2000

A High-Performance Liquid Chromatography System With Fenton's Reagent For Detection Of Gas-Phase Hydrogen Peroxide, Jun Liu

UNLV Retrospective Theses & Dissertations

A simple quantitative HPLC method for analysis of gas-phase hydrogen peroxide (H2O2) has been developed. This method relies on conversion of sodium salicylate to dihydroxybenzoic acid, sodium salts by using Fenton's reagent (a mixture of H2O2 and ferrous iron) under the proper conditions. Hydroxyl radicals generated from Fenton's reagent will react with sodium salicylate and generate 2,3-, 2,4-, and 2,5-dihydroxybenzoic acid (sodium salts), which can be quantitatively determined by HPLC-UV at wavelength 310 nm. The cryogenic sampling system was chosen to collect gasphase H2O2. The detection limit for this method is 0.03 ppm. The seasonal variation of H2O2 in Las …

Sodium Metasomatism And Magnesio-Riebeckite Mineralization In The Wilson Ridge Pluton, Deborah Ann Potts

UNLV Retrospective Theses & Dissertations

The Wilson Ridge pluton contains a rare occurrence of hydrothermal sodic amphibole. hydrothermal amphibole occurs as fracture coatings, veinlets, dense stockwork-type networks, and diffusive alteration fronts. Electron microprobe analyses of the hydrothermal amphibole reveal a range of Na-rich compositions, most notably magnesio-riebeckite. Magnesio-riebeckite in the Wilson Ridge pluton formed by Na-metasomatism related to subsolidus hydrothermal alteration involving Na-rich fluids of meteoric origin. Whole-rock geochemistry of samples from zones of hydrothermal amphibole show enrichment of Na2O (>9.6 wt. %) and depletion of K2O (0.15 wt. %) and CaO (2.4 wt. %) relative to unaltered host rock. Secondary fluid inclusions associated …

Automated Mammographic Mass Shape Classification Using Wavelets And Neural Networks, Nithya Shanmugam

UNLV Retrospective Theses & Dissertations

The objective of the thesis is to demonstrate the utility of wavelet transforms with artificial neural networks for the classification of mammographic mass shapes. A fully automated mammographic classification system has been developed to distinctly classify mass shapes as either round, which typically indicates the absence of breast cancer, or irregular, which typically indicates the presence of cancer. First, a wavelet transform was applied to the radial distance measure (RDM) of the mass shapes to obtain multiscale decomposition. The discrete wavelet transform and wavelet packet decompositions were investigated. The second step was the computation of scalar-energy features from the wavelet …

An Application Of Optimal Control Theory In Welfare Economics, Steven Ernest Scroggin Jan 2000

An Application Of Optimal Control Theory In Welfare Economics, Steven Ernest Scroggin

UNLV Retrospective Theses & Dissertations

We consider the maximization of a functional representing social welfare over continuous time. A social welfare functional (SWF) is an integral that models social welfare as a function of individual consumption, individual utility of consumption and the value of utility aggregated across individuals. A SWF may be subject to constraints in the form of differential or integral equations and inequalities, which represent the production possibilities of the economy. We solve the optimization problem by applying the Pontryagin maximum principle. We consider an autarky and a command economy. We explore the interaction of impatience and productivity in autarky and the implications …
