Forgotten Glory - Us Corps Cavalry in the Eto

Forgotten Glory - Us Corps Cavalry in the Eto

Access: Use of this item is restricted to the UNT Community.
Date: May 2014
Creator: Nance, William Stuart
Description: The American military experience in the European Theater of Operations during the Second World War is one of the most heavily documented topics in modern historiography. However, within this plethora of scholarship, very little has been written on the contributions of the American corps cavalry to the operational success of the Allied forces. The 13 mechanized cavalry groups deployed by the U.S. Army served in a variety of roles, conducting screens, counter-reconnaissance, as well as a number of other associated security missions for their parent corps and armies. Although unheralded, these groups made substantial and war-altering impacts for the U.S. Army.

The Function of Social Structure in Controlling Violent Crime in Turkey

The Function of Social Structure in Controlling Violent Crime in Turkey

Access: Use of this item is restricted to the UNT Community.
Date: December 2010
Creator: Guclu, Idris
Description: This dissertation examines the relationship between social structural factors and violent crime rates in Turkey. The relationship between social structural characteristics and violent crime is worth exploring in areas that have attracted little academic attention, such as violent crime in Turkey. In order to understand and prevent the occurrence of crime, researchers have long investigated possible factors related to crime. Examining how crime varies across different regions can help us to understand underlying reasons for violent crime, which is considered one of the enduring problems in society. The findings of this research, to some extent, support the assumptions of social disorganization theory regarding the distribution of violent crime. Both the findings of multivariate and bivariate analysis indicated that poverty, unemployment, and family disruptions may have a positive effect on the distribution of violent crime in the cities of Turkey. The analysis of the effects of the social structure variables through the mediating variables, such as religious institutions, libraries and voluntary associations on the number of violent crimes and violent criminals, to some extent, support the tenets of social disorganization theory. However, all mediating variables cannot mediate all the indirect effects of social structural covariates. In brief, none of their indirect ...

Description: Symbiotic nitrogen fixation occurs in plants harboring nitrogen-fixing bacteria within the plant tissue. The most widely studied association is between the legumes and rhizobia. In this relationship the plant (legumes) provides the bacteria (rhizobia) with reduced carbon derived from photosynthesis in exchange for reduced atmospheric nitrogen. This allows the plant to survive in soil, which is low in available of nitrogen. Rhizobia infect and enter plant root and reside in organs known as nodules. In the nodules the bacteria fix atmospheric nitrogen. The association between the legume, Medicago truncatula and the bacteria Sinorhizobium meliloti, has been studied in detail. Medicago mutants that have defects in nodulation help us understand the process of nitrogen fixation better. One such mutant is the Mtnip-1. Mtnip-1 plants respond to S. meliloti by producing abnormal nodules in which numerous aberrant infection threads are produced, with very rare rhizobial release into host plant cells. The mutant plant Mtnip-1 has an abnormal defense-like response in root nodules as well as defects in lateral root development. Three alleles of the Mtnip/latd mutants, Mtnip-1, Mtlatd and Mtnip-3 show different degrees of severity in their phenotype. Phylogenetic analysis showed that MtNIP/LATD encodes a protein belonging to the NRT1(PTR) family of ...

Gentrification in Oklahoma City:  Examining Urban Revitalization in Middle America

Gentrification in Oklahoma City: Examining Urban Revitalization in Middle America

Access: Use of this item is restricted to the UNT Community.
Date: August 2011
Creator: Petty, Clint C.
Description: Gentrification applies not only to the largest and oldest cities; it is a multi-scalar phenomenon playing out in smaller and less prominent settings as well. This study examines temporal changes in property values, demographic characteristics, and types of businesses in the central Oklahoma City area. A major urban revitalization project which began in 1993 created strong gentrification characteristics near the renewal's epicenter, the Bricktown entertainment district. Data suggest that several specific neighborhoods in the surrounding area exhibited rising property values, improving educational attainment rates, decreasing household sizes, and a shift toward cosmopolitan retail activity. While it is evident that Bricktown has been transformed, the socio-economic traits of surrounding neighborhoods have been altered by the ripple effects of urban renewal.

The Girl Disappeared: the Prostitute of La Isla De Santa Flora

The Girl Disappeared: the Prostitute of La Isla De Santa Flora

Access: Use of this item is restricted to the UNT Community.
Date: May 2013
Creator: Winston, Michael
Description: The novella, The Girl Disappeared, focuses on the life of Emalia, a street kid from Mexico. She is taken from the streets of Veracruz and forced into a life of prostitution on the fictitious island of La Isla de Santa Flora. The primary conflict that drives the action of the story is her pending choice between escaping her life of slavery and saving another young woman who is on the verge of being forced into a life of prostitution as well. The novella, as a literary piece, dwells on the question of character agency and explores the multilayered nature of code switching. Language for these women becomes a tool in their struggle against their captives and a means of self-preservation, or sanctuary, as they use their growing bilingualism to foment a limited agency, to act in their own defense.

Description: The preface, "Against Buses: Charles Baxter and the Contemporary Epiphany" deals with the epiphany as a potential ending to short stories. Baxter holds that epiphanies are trite and without purpose in today's fiction. I argue that Baxter's view, while not without merit, is limiting. Beginning with James Joyce and Katherine Anne Porter and moving to my own work, I discuss how some epiphanies, particularly false ones, can enhance rather than detract from excellent fiction. Five short stories make up the remainder of this thesis: "Dedication," "Taking it with You," "Transition to Flowers," "Profile in Courage," and "Henderson Street Bazaar."

Identification of highly gifted 5- and 6-year-old children: Measures to predict academic achievement.

Identification of highly gifted 5- and 6-year-old children: Measures to predict academic achievement.

Access: Use of this item is restricted to the UNT Community.
Date: May 2010
Creator: Runyon, Lisa
Description: Studies indicate the educational needs of highly gifted students are best met through accelerated learning. It is difficult to recognize very young children that are suited for an accelerated curriculum because younger students frequently lack school records or portfolios used to identify gifted students. This study examined the accuracy of cognitive ability and achievement tests in predicting academic achievement by the end of second grade, correlating test results and final grade averages collected from sixteen children ages five to six who entered a public school program for high-ability learners in kindergarten. A multiple regression analysis indicated the Wechsler Preschool and Primary Scale of Intelligence produced the highest mean IQ score and a strong correlation with reading achievement. The Wechsler Individual Achievement Test contributed in small part to the prediction of academic achievement. The Naglieri Nonverbal Ability Test and the Kaufman Brief Intelligence Test-Second Edition had negative correlations with final grade averages, indicating they are not predictors of academic achievement for these students.

Creator: Meckfessel, Matthew Harold
Description: The model legume, Medicago truncatula, is able to enter into a symbiotic relationship with soil bacteria, known as rhizobia. This relationship involves a carbon for nitrogen exchange in which the plant provides reduced carbon from photosynthesis in exchange for reduced, or “fixed” atmospheric nitrogen, which allows the plant to thrive in nitrogen depleted soils. Rhizobia infect and enter plant root organs, known as nodules, where they reside inside the plant cell in a novel organelle, known as the symbiosome where nitrogen fixation occurs. the symbiosome is enriched in plant proteins, however, little is known about the mechanisms that direct plant proteins to the symbiosome. Using the M. truncatula ENOD8 (MtENOD8) protein as a model to explore symbiosome protein targeting, 3-cis domains were identified within MtENOD8 capable of directing green fluorescent protein (GFP) to the symbiosome, including its N-terminal signal peptide (SP). the SP delivered GFP to the vacuole in the absence of nodules suggesting that symbiosome proteins share a common targeting pathway with vacuolar proteins. a time course analysis during nodulation indicated that there is a nodule specific redirection of MtENOD8-SP from the vacuole to the symbiosome in a MtNIP/LATD dependent manner. GFP expression by the MtENOD8 promoter revealed spatial ...

Description: In teleost fishes the neurochemicals involved in sensing and responding to hypoxia are unresolved. Serotonergic branchial neuroepithelial cells (NECs) are putative O2 chemoreceptors believed to be homologous to the neural crest (NC) derived APUD (amine-precursor uptake and decarboxylation) pulmonary NECs and carotid body type-1 glomus cells. Branchial NECs contain serotonin (5-HT), thought to be central to the induction of the hypoxic cardioventilatory reflexes. However, application of 5-HT in vivo does not elicit cardioventilatory reflexes similar to those elicited by hypoxia. But previous in vitro neural recordings from glossopharyngeal (IX) afferents innervating O2 chemoreceptors in the trout gill show the same discharge response to hypoxic conditions as does that of acetylcholine (ACh) application. This evidence strongly supports the cholinergic hypothesis of chemoreceptor impulse origin rather than a serotonergic-induced impulse origin model. We therefore hypothesized that NECs contain ACh among other neurochemicals in cells belonging to the APUD series. Although serotonergic branchial NECs did not colocalize with ACh using immunohistochemical methods, several populations of ACh and/or tyrosine hydroxylase (TH) (catecholaminergic) positive, dopamine (DA) negative, cells were found throughout the second gill arch of the channel catfish Ictalurus punctatus. In addition, the NC derivation marker zn-12 labelled the HNK-1-like epitope (Human natural killer) ...
