This study used a geographic information system (GIS) and an empirical pollutant load model to estimate average annual pollutant loads contained in storm water charges from the City of Carrollton, Texas. The Geographic Resource Analyses Support System (GRASS) was used to create a number of spatial data layers as input variables to a model that estimates loads in Kilograms/Hectare/Year, and Kilogram/Basin/Year. Average annual pollutant loads for twelve pollutants were derived from average annual rainfall/runoff volumes, coupled with Local Dallas/Fort Worth Metroplex storm water Event Mean Concentrations.

Twenty-nine (Group One, June 8,1995) grass carp (Ctenopharyngodon idella) and five (Group Two, April 18, 1996) grass carp were radio-tagged to monitor movement patterns and habitat preferences on North Lake, a 335 hectare multi-use reservoir located in Irving, Texas. Overall fish mean Average Daily Movement (ADM) rates were 49.2 meters/day (during Half One, 6/8/95-11/30/95) and 5.3 meters/day (during Half Two, 12/14/95-6/6/96). Aquatic macrophtye distribution data were obtained. Radio-tagged grass carp were located in Hydrilla verticillata infested areas increasingly throughout the study, however, percent frequency of Hydrilla along 15 transects did not decrease. Radio-transmitters were equipped with temperature-sensors (10-35 Celsius range). Results indicated that radio-tagged grass carp showed no avoidance of areas of North Lake with elevated water temperatures. Radio-tagged grass carp dispersed quickly from stocking point, then moved into littoral areas infested with Hydrilla. After an initial movement period, most fish remained in a localized area.

The purpose of this study is to examine domestic violence as it occurs in same-sex male relationships. Data were collected by in-depth interviews with twenty-five gay males, who were between the ages of 23 and 43, and who had previous experience being in a homosexual relationship where domestic violence was present. The major findings of this study include the respondents': 1) definitions of domestic violence and abuse; 2) the type of domestic violence or abuse personally experienced; and 3) reasons they believe domestic violence or abuse occurs in these types of relationships. This study illustrates the need for further research in this area of domestic violence and for programs or services targeted for this specific population.

The purpose of this study is to determine the impact on student use of electronic information systems when teachers have been given instruction on their use. By providing teachers with a solid introduction to the technology, a handy reference book, and an easy-to-use evaluation tool, it is expected that they will incorporate information found on the internet into their lessons at least twice a month. In addition, teachers will allow students to access information on their own, provided computers and Internet access are available, at least once a month.

The purpose of this study was to determine if there is a difference in opinion between chain and franchise restaurant managers and independent owner/operators toward the effects of a smoking ordinance. Results of this study showed a significant statistical difference between restaurateur groups toward the perception of economic effects.

This study was conducted to determine which incentive programs best influence young workers in corporate casual restaurants. The server and bar staff of the Chili's division of Brinker International, Inc. were surveyed in 18 stores in the Dallas area. From the sample. 356 usable surveys were received. The study was designed to obtain feedback about existing and future incentive programs that will enhance development of a positive working environment, along with higher productivity and a lower turnover rate.

This thesis examined student-participants' self-reported use of romantic relational maintenance strategies and their partners' reports of relational satisfaction. Additionally, individuals outside the romantic relationship reported on student-participants' general communicator style. The research proposed that general style reports would be predictive of relational maintenance strategy usage and of romantic partners' relational satisfaction. The study found that general style behaviors may not be indicative of relational maintenance strategy usage or romantic partners' relational satisfaction. Tests of sex differences revealed that females' expression of various relational maintenance strategies and style behaviors are associated with male partners' relational satisfaction; however, no results were obtained indicating specific behaviors expressed by males result in female partners' relational satisfaction.

A study of the phytoplankton communities of Lake Ray Roberts was conducted at three sampling sites on two sampling dates during the summer of 1995, assessing both community structure and chlorophyll a concentrations. Eight similarity indices were then used to characterize and compare the communities of these sites. Both community similarity and chlorophyll a concentrations were evaluated using a minimum detectable difference equation to determine the amount of change that must occur in these parameters in order to be deemed statistically significant. The Bray-Curtis Index was shown to be the most adequate index evaluated, and was subsequently used in conjunction with bootstrap analysis to determine the similarity between the three sampling sites.

This study was designed to determine if impingement and entrainment by cooling water intake at the Comanche Peak Steam Electric Station have an adverse impact upon the Squaw Creek Reservoir fish population. The yearly impingement of fish was estimated to be 262,994 of 14 species. The threadfin shad (Dorosoma petenense) accounted for 96% of this total. Entrainment of eggs and larvae for a five month period was estimated to be 15,989,987 and 42,448,794 respectively. Two fish population studies were performed on Squaw Creek Reservoir to help assess impact. It was determined that the losses due to impingement and entrainment have no adverse impact upon the fish population of Squaw Creek Reservoir.

The City of Denton Pecan Creek Wastewater Treatment Facility has periodically failed effluent toxicity testing. A Toxicity Identification Evaluation has determined that Diazinon in the effluent is contributing to the observed toxicity. Chlorpyrifos is also implicated as a factor. The City of Denton constructed a half acre experimental wetland to remove Diazinon related toxicity. Results from spiking and microcosm experiments indicate that the wetland can reduce the Diazinon.

A total of 192 largemouth bass were caught at Lake Ray Roberts, Texas (1995) to investigate five controversial bass angling techniques relative to hooking mortality. The bait types were Texas-rigged scented and non-scented plastic worms, Carolina-rigged scented and non-scented plastic worms, and live golden shiners. Overall hooking mortality was 21.87% and mortality was dependent upon bait type. Highest mortality resulted from the Texas-rigged scented lures, while the lowest mortality was generated by live golden shiners. A creel survey indicated that few anglers were having success with the investigated baits. Factors that had a confirmed effect on hooking mortality were hooking location and water temperature. Hooking mortality was not excessive compared to other similar studies.

Castilian law developed during the Reconquest of Spain. Women received certain legal rights to persuade them to move to the villages on the expanding frontier. These legal rights were codified in Las Siete Partidas, the monumental work of Castilian law, compiled in the thirteenth century. Under Queen Isabella, Castilian law became the law of all Spain. As Spain discovered, explored, and colonized the New World, Castilian law spread. The Recopilacidn de Los Leyes de Las Indias complied the laws for all the colonies. Texas, as the last area in North America settled by Spain, retained Castilian law. Case law from the Bexar Archives proves this for the Villa of San Fernando(present-day San Antonio). Castilian laws and customs persisted even on the Texas frontier.

This project demonstrates the construction of a land planning geographic information system (GIS) for Tarrant County, and explores how the technology could be used to select sites for a county wide open space preservation plan. As Texas' Tarrant County continues to undergo rapid change due to growth and expansion, the need for proactive, resourceful community planning is greater than ever. One crucial issue facing the region is how to preserve open areas that serve the county's citizens' ecological, recreational, cultural and economic needs. In order to assess how much open space is needed and which sites should be considered for special attention, large amounts of varied spatial information must be analyzed. The answer to effectively dealing with such data sets is a geographic information system (GIS) that stores all pertinent data digitally and allows for its manipulation through use of a computer software package. This project demonstrates the construction of a land planning GIS for Tarrant County, and explores how the technology could be used to select sites for a county wide open space preservation plan.

Despite site-based decison making (SBDM) educational mandates, research determined the virtual exclusion of parents, family, and/or home as co-authoritative voice in Texas public school district mission statements. Qualitative analysis determined six parent roles within 155 inclusive mission statements through rhetorical deconstruction, a text-based grammatical evaluation procedure; quantitative analysis determined no significance between inclusive and exclusive districts in factors of size, socioeconomic status, and ethnicity. The implications of this study add further support to the growing parental insistence for greater educational decision-making options: ie., home schooling, voucher system, and charter schools.
