Evaluation of the Influence of Non-Conventional Sources of Emissions on Ambient Air Pollutant Concentrations in North Texas

Description: Emissions of air pollutants from non-conventional sources have been on the rise in the North Texas area over the past decade. These include primary pollutants such as volatile organic compound (VOC) and oxides of nitrogen (NOx) which also act as precursors in the formation of ozone. Most of these have been attributed to a significant increase in oil and gas production activities since 2000 within the Barnett Shale region adjacent to the Dallas-Fort Worth metroplex region. In this study, air quality concentrations measured at the Denton Airport and Dallas Hinton monitoring sites operated by the Texas Commission on Environmental Quality (TCEQ) were evaluated. VOC concentration data from canister-based sampling along with continuous measurement of oxides of nitrogen (NOx), ozone (O3), particulate matter (PM2.5), and meteorological conditions at these two sites spanning from 2000 through 2014 were employed in this study. The Dallas site is located within the urban core of one of the fastest growing cities in the United States, while the Denton site is an exurban site with rural characteristics to it. The Denton Airport site was influenced by natural gas pads surrounding it while there are very few natural gas production facilities within close proximity to the Dallas Hinton site. As of 2013, there were 1362 gas pads within a 10 mile radius to the Denton Airport site but there were only 2 within a 10 mile radius to Dallas Hinton site. The Dallas site displayed higher concentrations of NOx and much lower concentrations of VOC than the Denton site. Extremely high levels of VOC measured at the Denton site corresponded with the increase in oil and gas production activities in close proximity to the monitoring site. Ethane and propane are two major contributors to the measured VOC concentration, suggesting the influence of fugitive emissions of natural gas. ...

An Evaluation of the Influence of Parent Interest on Child Achievement

Description: A number of investigations of pupil progress in school have definitely shown that the percentage of failure in the first grade is much higher than in the other grades. In the light of these investigations, it is safe to assume that there must be a number of contributing factors to this failure in grade progress. The nature of these factors and what the school can do, if anything, to mitigate their influence on pupil progress in the first grade constitute a challenge to educational research. The present study undertakes an investigation along these lines. The purpose of this study is threefold: (1) to investigate the need for a pre-school program; (2) to study the reported values of such a program; and (3) to survey a certain number of schools to determine the extent and nature of preschool programs if any.

An Evaluation of the Newbery Medal Books

Description: The writer's purpose in this study has been to make a thorough investigation of the Newbery Medal books to determine if they represent the best literature suitable for children's reading that has been published since 1922, and to investigate carefully the group as a whole to see if the books possess those rare qualities and characteristics which, deservedly, would set them apart from the ordinary type of books usually designated as suitable for children's reading.

Evaluation of the Preparation for Adult Living Training Program for Severely Emotionally Disturbed Adolescents in a Residential Treatment Center

Description: The purpose of this study was to determine the effectiveness of the Preparation for Adult Living skills training program by measuring the learning gains and learning outcomes of students participating in the training. The quasi-experimental posttest control group design was used. A treatment sample of twelve students received the Preparation for Adult Living training. A nontreatment sample was selected by matching the characteristics of educational and reading level and the gender of twelve students with no previous independent living skills training with those of the treatment sample. Students in the treatment sample were tested for learning gains using the Preparation for Adult Living Test. Both the treatment and nontreatment sample were tested using the post-training Preparation for Adult Living Scale to determine the level of their learning outcomes. The Preparation for Adult Living Test results were analyzed using the t-test for correlated samples of pretests and posttests. The t-test for independent samples was used to analyze the Preparation for Adult Living Scale results to determine the students' learning outcomes. A Pearson r correlation coefficient was calculated for Preparation for Adult Living Scale scores to determine if a relationship existed between employment and the life coping skills of the treatment sample. The findings indicated that no learning gains were made during the training, but that the training had an impact on the students' post-training life-coping skills. A strong relationship was found between the specific life-coping and employment skills of the treatment sample. Investigation of the reliability and validity of the Preparation for Adult Living Test and Scale instruments was recommended.
