Research points out the many complex problems of the disadvantaged child. The purpose of establishing many preschool programs throughout this country has been to seek the most effective ways of educating the culturally deprived and to utilize the standardized measurements to assess various programs. The purpose of the present study is to evaluate the intellectual functioning and sensory-motor abilities of the disadvantaged child at the preschool level, to determine his growth in these areas during his participation in the program, and to determine whether or not four different teaching models are instrumental in bringing about intellectual and sensory-motor improvements.

The problem in this study has a three-fold purpose: to evaluate the work performance, as ranked by employers and teachers, of a group of employed graduates of business education of the sunset high School of Dallas, Texas; to evaluate the personality traits demonstrated by the employees on the job in relation to the personality traits demonstrated in school; and to analyze these evaluations to secure suggestions for improving the course of study, including the amount of emphasis which should be placed on the various phases of the instructional program.

The purpose of this study was to conduct a case study of the controller function of one of the assembly plants, which is typical in organization and functions of all the assembly plants within the Ford Division. The Controllership of the Dallas Assembly Plant of the Ford Motor Company was studied, and its functions and relationship to management were shown.

A study of macroinvertebrate colonization and assemblages, including secondary productivity of the familiar bluet damselfly or Enallagma civile Hagen (Odonata: Coenagrionidae), associated with the aquatic macrophytes Heteranthera dubia (Jacq.) MacMill. (water stargrass) and Potamogeton nodosus Poir. (American pondweed) was conducted at the Dallas Floodway Extension Trinity River Project (DFE) Lower Chain of Wetlands (LCOW), Dallas, TX, from September 2010 through November 2011. Macroinvertebrate abundance, taxa richness, Simpson's index of diversity, and Simpson's evenness from the two macrophytes and from three different wetland cells of varying construction completion dates, water sources, and native aquatic vegetation establishment were analyzed along with basic water quality metrics (temperature °C, pH, dissolved oxygen mg/L, and conductivity µs/cm). E. civile nymphs were separated into five developmental classes for secondary productivity estimations between macrophytes and wetland cell types. Mean annual secondary productivity in the DFE LCOW among two macrophytes of E. civile was 1392.90 ash-free dry weight mg/m²/yr, standing stock biomass was 136.77 AFDW mg/m2/yr, cohort production / biomass (P/B) ratio was calculated to be 4.30 / yr and the annual production / biomass (P/B) ratio was 10.18 /yr.

Agroecus compreende seis espécies, de distribuição Neotropical e hábito alimentar fitófago, sendo A. griseus Dallas, 1851 de importância econômica em cultivo de milho. Neste trabalho a monofilia do gênero foi testada sob o método de parcimônia usando caracteres discretos e caracteres contínuos e dois métodos de pesagem, pesagem igual e pesagem implícita. O gênero é monofilético em todas as quatro análises, com uma árvore encontrada. A revisão do gênero com descrição de genitálias de macho e fêmea baseada em caracteres morfológicos é feita. O macho de A. lizerianus, até então desconhecido, é descrito. A genitália interna de fêmea é descrita para todas as espécies conhecidas. Novas localidades são adicionadas ao conhecimento da distribuição de A. griseus, A. scabricornis, A. brevicornis e A. lizerianus. Ilustrações comparativas de genitália externa e interna das espécies e uma chave dicotômica para a identificação das espécies são fornecidas. / Agroecus comprises six species, has Neotropical distribution and phytophagous feeding habit, of which A. griseus is economically important for corn crops. In this work the monophyly of the genus was tested using parsimony based on discrete characters and continuous characters equal weighing and implicit weighing methods were used. Agroecus was recovered monophyletic in all the four analysis, with only one resulting tree. A review of the genus with emphasis on the male and female genitalia based in morphological characters was provided. The unknown male of A. lizerianus was described. The internal genitalia of the female was described for all the known species. New localities are added to the distribution of A. griseus, A. scabricornis, A. brevicornis e A. lizerianus. Comparative illustrations of the external and internal genitalia of the species and a dichotomous key to identify them were provided.

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.

Persistence has been identified as an issue at all levels of higher education, and numerous strategies have been attempted to stem the flow of students who leave an institution before completing their programs of study. Persistence research abounds at the community college, four-year college and university levels, but little research on the subject is available at the postsecondary proprietary level. The purpose of this qualitative case study was to research and describe the developmental program recently undertaken at The Art Institute of Dallas (AID), and to compare the findings to the literature on community colleges. Objectives were to 1) examine the forces which caused AID to implement a developmental program; 2) examine how the program was perceived to be working; 3) compare the description of the program at AID to descriptions of those in community colleges, as described in the literature; 4) examine individual perceptions of benefits or drawbacks to the school as a direct result of the new program; and 5) determine if the key informants saw the developmental program as a vehicle to raise persistence and enhance student success. Originally, AID was an open admissions school, offering basic skills help only in tutorial situations. With the addition of General Education courses to the various curricula, the need for an Academic Improvement Center was discerned. Eventually, the school also saw the need to establish admissions standards, coupled with placement testing, to identify and serve underprepared students. Persistence became an issue, along with the state mandate of The Texas Academic Skills Program (TASP), and both contributed to the establishment of a comprehensive developmental education program. Results indicated the need for a student better prepared in numeracy and literacy skills, reflected in the requirements of employers needing employees with abilities to read technical documents, to write reports, to work in teams, and to solve problems. The findings of this study suggest the addition of a comprehensive developmental education program at AID positively affected student persistence. Just as the research on community college developmental studies history, development, and progress unfolded, so also went this postsecondary proprietary school. / Graduation date: 1998
