This study was designed to identify the knowledge and skills that welders employed in certain areas of manufacturing and fabrication in the Dallas-Fort Worth, Texas Metropolitan Area should possess.

The purpose of the paper is to develop projections of occupational employment in the Dallas and Fort Worth Standard Metropolitan Statistical Areas (SMSA) using Area Projection Method A, developed by the U.S. Bureau of Labor Statistics (BLS) . An objective of the paper is to determine whether reasonable projections can be made for the Dallas and Fort Worth areas using the method. The projections and results can be used by local manpower and education planners to satisfy their planning requirements. The final chapter concludes that Method A does produce reasonable projections, but points out that the projections lack detail. Their value lies in projecting the overall trend and direction of the composition of employment, and their usefulness is primarily in policy making.

The study determines and evaluates changes in the 10:00 p.m. newscasts of the Dallas-Fort Worth network affiliates following personnel and ownership changes, and a reduction in length of one station's newscast. Scripts and audio recordings of the newscasts were collected during four-week periods before and after the changes. The data were analyzed and supplemented with interviews conducted with the stations' news directors and producers. Conclusions drawn were that ownership changes had more impact on the presentation of the news than on its content, changes in anchormen and producers had more effect on presentation than on content, and a reduction in news time caused changes in the content of a television newscast.

This study compares the May, 1974 and May, 1975 editions of suburban daily newspapers in the Dallas-Fort Worth metroplex. The purposes of the study were to determine how, when, and why suburban daily newspapers in the metroplex altered their editorial content and to evaluate the effects of the changes on circulation. The thesis is organized into four chapters. Chapter I introduces the study. Chapter II gives a historical overview. Chapter III analyzes the data. Chapter IV contains some conclusions. Some conclusions that emerged from this study include: 1. Suburban newspapers have small editorial staf fs. 2. Eight of the newspapers altered their content. 3. The changes helped them maintain or increase their circulation. 4. All of the editors responding to the questionnaire said that local news and sports are their primary goals.

The purpose of this study is to determine the effects of water pollution control on financing municipal water pollution control facilities in selected cities in North Central Texas. This objective is accomplished by addressing the following topics: (1) the cost to municipalities of meeting federally mandated water pollution control, (2) the sources of funds for financing sewage treatment, and (3) the financial implications of employing these financing tools to satisfy water quality regulations. The study makes the following conclusions regarding the impact of water pollution control costs on municipalities in the North Central Texas Region: 1) The financing of the wastewater treatment requirements of the Water Pollution Control Act Amendments of 1972 will cause many municipalities to report operating deficits for their Water and Sewer Fund. 2) A federal grant program funded at the rate of 75 per cent of waste treatment needs will prevent operating deficits in the majority of cities in which 1990 waste treatment needs constitute 20 per cent or more of the expected Water and Sewer Fund capital structure. 3) A federal grant program funded at the average rate of 35 per cent of needs will benefit only a small number of cities. 4) The federal grant program does not improve the operating position of cities in which needs are less than 20 per cent of the total expected capital structure. 5) The state grant program shows the greatest incidence of producing municipal Water and Sewer Fund operating deficits. 6) In order to eliminate operating deficits, cities will need to increase Water and Sewer Fund income in amounts ranging from 0.3 per cent to 571.6 per cent.

Urban landscapes are quickly replacing native habitat around the world. As wildlife and people increasingly overlap in their shared space and resources, so does the potential for human-wildlife conflict, especially with predators. Bobcats (Lynx rufus) are a top predator in several urban areas across the United States and a potential contributor to human-carnivore conflicts. This study evaluated the movements and habitat use of bobcats in the Dallas-Fort Worth (DFW), Texas metroplex. Spatial data were collected from 10 bobcats via Global Positioning Satellite (GPS) for approximately one year. Average home range size was 4.60 km2 (n=9, SE=0.99 km2) for all resident bobcats, 3.48 km2 (n=5, SE=1.13 km2) for resident females, and 6.00 km2 (n=4, SE=1.61 km2) for resident males. Resource selection function (RSF) models show that bobcats avoid areas close to and far from grasslands and low-medium development, while selecting for these areas at intermediate distances. Bobcats also selected areas closer to developed open space, agricultural areas, and railroads. In addition, camera trap data analyzed with spatially explicit capture-recapture (SECR) models informed by the RSF results estimated a population density of 0.64 bobcats/km2 (SE = 0.22). Bobcats in DFW have significantly smaller home ranges and occur at higher densities compared to rural bobcat populations. Home ranges were also slightly smaller and densities higher than the most closely similar peri-urban bobcat studies. These differences likely arise due to the abundant urban prey species the DFW landscape provides despite limited space and habitat for bobcats. The dense urban development surrounding this population of bobcats may also discourage dispersing from the area, and contributing to higher densities. These results provide information to facilitate management of urban bobcats by providing new insight into how bobcats live amidst people in urban areas.

The primary motivation for conducting this study was the apparent conflict between Texas Education Agency guidelines for a vocational cooperative education program and the realities of actual program operation. In the program the mid-management student receives instruction, through a cooperative arrangement between the college and employers, in both academic courses and related vocational instruction.

This thesis presents methods to place landing sites for the Urban Air Mobility (UAM) concept. The analysis shows an integrated approach to establish UAM landing site requirements, place landing sites based on predicted demand, and estimate the costs associated with UAM landing sites. This thesis also makes estimates of fares associated with UAM operations. The methods presented are applied to three large urban centers in the United States. The analysis assumes an all-electric, advanced multi-rotor aircraft with autonomous navigational and Vertical Takeoff and Landing (VTOL) capabilities to estimate UAM landing site requirements. The thesis presents the land area requirements of UAM landing sites using Federal Aviation Administration heliport design criteria considering ground-taxi configurations. The analysis performed employs a UAM vehicle with an equivalent Rotor Diameter (RD) of 43 feet. In this thesis, UAM demand is estimated using a mode choice model developed in a companion study (UAM Scenario Analysis). The methodology to locate UAM landing sites includes splitting and consolidation of UAM landing sites considering the Zillow Transaction and Assessment Dataset (ZTRAX) to introduce land-use size and cost constraints. The sites are split using a K-Means clustering method and are consolidated using a simple center of mass approach where the demand of each landing site is analogous to mass. The results presented in this thesis apply to 75 and 200 landing sites in each region and assume passenger Cost-Per-Mile (CPM) of $1.20 and $1.80, respectively. This thesis presents a comparative study on how the availability of land affects the splitting, consolidation, and relocation of UAM landing sites for each region, the number of landing sites, and the cost per passenger-mile. / Master of Science / This thesis aims at the landing sites for the Urban Air Mobility (UAM) concept for commuting passengers in Northern California (17 counties), Southern California (9 counties), and Dallas-Fort Worth (12 counties) region. The aircraft for this service is designed to be an all-electric advanced multi-rotor aircraft with autonomous navigational and Vertical Takeoff and Landing (VTOL) capabilities. The commuting trips considered is focused on passengers traveling to work from home and back. This thesis presents the land area requirements of these landing sites, which are calculated from the Federal Aviation Administration's (FAA) Advisory Circular 150/5390-2C using ground-taxi configuration for a typical representative aircraft of an equivalent rotor diameter (RD) of 43 feet. The landing sites are then split into smaller sites and consolidated into larger sites. This thesis also presents a list of plots of land located within the 0.5 statute-mile boundaries of the landing sites for relocation. This entire analysis is based on the availability of land from the Zillow Transaction and Assessment Dataset (ZTRAX). The results presented in this thesis are for 75 and 200 landing sites set in the study area for a passenger Cost-Per-Mile (CPM) of $1.2 and $1.8, respectively. The results show how the availability of land changes for different CPM for a set of landing sites and affects the splitting, consolidation, and relocation of landing sites for each region. In the end, the thesis presents conclusions and recommendations unique to each region.

This study consists of two parts, the completed videotape production and the production book. The videotape explores the history, organizational structure, and training requirements of the Dallas/Fort Worth Airport Department of Public Safety. A copy of the videotape is shelved in the North Texas State University Media Center Library. The production book describes background preproduction, production, and postproduction of the videotape. Problems, their effects, and solutions are described. The study concludes that an effective videotape can be produced in-house with limited time, equipment, and personnel, at a cost far less than commercially produced films. The study makes specific recommendations for guidelines and planning of future productions.

The problem of this study was to determine to what extent industry was making use of closed circuit television as an implement of industrial security. The data for this study were provided by a group of thirty-two security chiefs of industry, and by another group of fifteen law enforcement officials in the Dallas and Fort Worth Metropolitan area. Of those industrial concerns making use of closed circuit television as an aid to security, a majority use the medium for surveillance of controlled access areas, with theft control and control of plant access following closely behind. For the most part, all surveyed thought that closed circuit television was very efficient.
