Sociolinguists working in Northern urban areas have shown that Hispanics who come in contact with African Americans sometimes acquire features of African American vernacular English (AAVE). However, the acquisition of AAVE features by Hispanics in the South has yet to be documented. Specifically, no one has studied the kind of English that Hispanics in Texas are acquiring. The present study investigates this issue through research in an inner-city area of Dallas: Oak Cliff. During the past twenty-five years, the population of Oak Cliff has changed from a largely African American community to include a substantial number of Hispanics. Though their neighborhoods remain fairly separate, sports and gangs provide an arena for extended contact. This study investigates the extent to which AAVE grammatical features are being acquired by bilingual Hispanic adolescents who hang out with African Americans. The analysis for this paper focuses on the relationship between contact and depth of acquisition of AAVE syntactic constraints on the use the copula (is/are, be). Preliminary results show that be+V+ing as an habitual form has been incorporated into the grammar of these subjects, suggesting fundamental changes towards an AAVE grammatical system.

This study examines the social and economic characteristics of the men who joined the Confederate Fourteenth Texas Infantry Regiment during the Civil War and provides a narrative history of the regiment's wartime service. The men of the Fourteenth Infantry enlisted in 1862 and helped to turn back the Federal Red River Campaign in April 1864. In creating a portrait of these men, the author used traditional historical sources (letters, diaries, medical records, secondary narratives) as well as statistical data from the 1860 United States census, military service records, and state tax rolls. The thesis places the heretofore unknown story of the Fourteenth Texas Infantry within the overall body of Civil War historiography.

The underwater optical climate of Lake Texoma was measured at eleven fixed stations from August 1996 to August 1997. Secchi transparency and submarine photometry characterized seasonal and spatial values of secchi depth (SD), vertical attenuation coefficient (η''), and depth of euphotic zone (Zeu). Indices of Zeu:SD and η'' × SD were compared with universally applied values derived from inland and coastal waters. Turbidity explained 76% of the variation (p = 0.0001) of η'' among water quality parameters, including chlorophyll-α. Using a spectroradiometer, spectral signatures of chlorophyll-α and turbidity were located. Stations with low turbidity exhibited a distinct green reflectance peak around 590-610 nanometers, indicating presence of chlorophyll-α. Stations with high turbidity exhibited a reflectance peak shift towards the red spectrum, making it difficult to detect the chlorophyll signature. Derivative analysis of the reflectance signal at 590-610, and 720-780 nanometers allowed discrimination of this chlorophyll signature from those of turbidity (0.66 ≤ r^2 ≤ 0.99).

The life history and case-building behavior of Molanna tryphena from two spring-fed tributaries in East Texas were studied from January 1997 to May 1998.

The purpose of this study was to assess rape attitudes and empathy levels of students at a university in North Texas. The Attitudes Toward Rape questionnaire and the Rape Empathy Scale were administered to 387 undergraduate students. Dependent variables were attitudes and empathy and independent variables were prior knowledge or experience as a rape victim, having female siblings, gender, marital status, and age. Significance was found between rape-intolerant attitudes and both prior experience as a victim (p < .001), and gender (p < .001). Significance was also found between empathy and experience as a rape victim (p < .035) and gender (p < .032).

This thesis estimates the spatial extent of chlorinated solvent contamination of the soil at the Naval Air Station, Dallas, then estimates the fate and transport of these contaminants, over time, using the Soil Transport and Fate database and the Vadose-Zone Interactive Processes (VIP) modeling software. Geostatistical analysis identifies two areas with serious chlorinated solvent contamination. Fate and transport modeling estimates that this contamination will degrade and disperse from the soil phase to below regulatory limits within one year, although there is a risk of groundwater contamination. Contaminants are estimated to persist in the water and air phases of the soil. Further sampling is recommended to confirm the results of this study.

The effect of the Civil War and Reconstruction on the southern planter elite remains a topic of interest to historians. Did the war ruin the planter class? Or, did they maintain economic, geographic, or social persistence? This study focuses on the persistence from 1850 to 1880 of five East Texas large planter families who owned one hundred or more slaves in 1860. An analysis of data primarily from county, state, and federal records formthe basis of this study. Four families persisted as wealthy influential members of their postbellum communities. One family remained geographically persistent but not wealthy. The experiences of these families suggest that large East Texas planter families found it possible to persist in spite of the Civil War and Reconstruction.

This thesis examines the letters, proclamations, and addresses of the four presidents of the Republic of Texas, David G. Burnet, Sam Houston, Mirabeau B. Lamar, and Anson Jones, to determine how these men faced the major crises of Texas and shaped policy regarding land, relations with Native Americans, finances, internal improvements, annexation by the United States, and foreign relations. Research materials include manuscript and published speeches and letters, diaries, and secondary materials.

An analysis of algal biomass measured by chlorophyll-a concentration in Lake Texoma was performed as a part of a monitoring program to develop baseline environmental data in order to detect the potential effects of engineered changes in chloride concentrations in the reservoir. This portion of the research project focused on two main research objectives. The first objective was evaluating the effect of sampling strategy on the ability to adequately reflect standing crop estimates and trends in algal biomass. Two sampling regimes utilizing replication of three versus ten samples were applied and then analyzed using a minimum detectable difference algorithm to determine the necessary magnitude of replication to represent the variation in the metric. Chlorophyll-a distribution was analyzed for zonation patterns expected in a river-run reservoir to establish the importance of representative sampling of river, transition and main lake zones of the reservoir for management decisions and trophic characterization.

Ninety-nine African-American undergraduates, at a historically Black college, completed the African American Acculturation Scale to compare fraternity/sorority members with independents' participation in Black cultural traditions versus dominant White society. Greek members were hypothesized to be more traditional, because these organizations represent ethnic enclaves, have duplicate institutions, and communicate ethnic socialization; findings did not support this, but reasons for joining did. They were more superstitious in their beliefs than nonmembers, likely related to pledgeship and initiation rituals. Validity data on the new measure were provided. Why participants join fraternities, why they like/dislike them, and what purposes they serve was also examined.

This thesis examined the relationships among immediacy of dress factors and affective learning factors as they pertain to relational communication. College students (N = 482) completed questionnaires indicating perceptions of selected nonverbal immediacy behaviors associated with their teacher's attire. The research predicted that there would be relationships between and among power and affinity of dress, dress immediacy and nonverbal immediacy. Further predictions were made concerning the associations among these variables, affective learning outcomes, and other teacher criteria. Analysis indicated that power of dress, affinity of dress and dress immediacy were viable nonverbal immediacy concepts which related to affective learning outcomes. Research findings indicated that certain instructor variables may also influence these relationships.

Wastewater effluent produced in the fiberglass manufacturing industry contains a significant amount of total suspended solids. Environmental regulations require pretreatment of effluent before it is discharged to the municipal wastewater treatment plant. Chemical precipitation by coagulation and flocculation is the method of pretreatment used at the Vetrotex CertainTeed Corporation (VCT). A treatability study was conducted to determine conditions at which the VCT Wastewater Pretreatment Plant could operate to consistently achieve a total suspended solids concentration ≤ 200-mg/L. Jar tests varied pH, polymer dosage, and ferric sulfate dosage. Total suspended solids and turbidity were measured to evaluate treatment performance. The data were used to determine an optimum set of conditions under project guidelines. Of twelve polymers screened, BPL 594 was selected as the most effective polymer. For cost efficiency in the wastewater pretreatment operation, recommendations suggested that treatment chemical injection be electronically controlled according to turbidity of the treated effluent.

A life history study of Callibaetis floridanus was conducted over the wet cycle of a playa on the Southern High Plains of Texas from June through September 1995.

In late 1861, the Confederate Texas government commissioned Joseph W. Speight to raise an infantry battalion. Speight's Battalion became the Fifteenth Texas Infantry in April 1862, and saw almost no action for the next year as it marched throughout Texas, Arkansas, and the Indian Territory. In May 1863 the regiment was ordered to Louisiana and for the next seven months took an active role against Federal troops in the bayou country. From March to May 1864 the unit helped turn away the Union Red River Campaign. The regiment remained in the trans-Mississippi region until it disbanded in May 1865. The final chapter quantifies age, family status, wealthholdings, and casualties among the regiment's members.

Little research has addressed the degree to which domestic violence is mutual and whether patterns are stable across women's relationships. Studies that exist have conflicting results. This study addressed these issues and the effects of sustaining past violence on women's expressions of violence in their current relationship. Archival data from a sample of severely psychologically abused community women (N = 92) and a sample of low-income community women (N = 836) were analyzed. Results showed the presence of mutual violence in women's current relationships which was not related to past partners' violence. Results regarding the stability of violence are weak, but indicate that the frequency and severity of violence across relationships sustained by women does not decrease across relationships. Overall, results supported the hypothesis that violence is mutual in the relationships of community women, although specific patterns may differ by ethnicity.
