The quality of the doctoral experience in education at Historically Black Colleges and Universities.

The quality of the doctoral experience in education at Historically Black Colleges and Universities.

Date: May 2006
Creator: Garrett, Rodney Ulysses
Description: This study describes the experiences of doctoral students in education at Historically Black Colleges and Universities (HBCUs). The study focused only on the 14 HBCUs that offer doctoral degrees in education. Twelve of the 14 eligible institutions agreed to participate in the study. A total of 47 doctoral students who were in their third year of study or close to completion participated in the study. These doctoral students completed a survey that was utilized in a national study of doctoral students at predominately white institutions and Ivy League institutions conducted by Golde and Dore in 2001. The purpose of this study was to determine if doctoral students in education at HBCUs are receiving a quality education and if they are being adequately prepared for their careers. This study offers 368 findings from which the doctoral experience in education at HBCUs can be comprehensively evaluated. It was determined that doctoral students in education at HBCUs do receive a quality education and are being effectively prepared for their careers.

Quality of work environment for counselor education faculty.

Quality of work environment for counselor education faculty.

Date: May 2005
Creator: McCortney, Amy Louise
Description: Though counselor education has always acknowledged the importance of work in the lives of individuals, there is a dearth of information concerning the worklives of counselor education faculty. The purpose of this study was to explore work and life variables that impact the work experiences of faculty members in counselor education. This study examined demographic or life variables including gender, age, ethnicity, sexual orientation, relationship status, and parenting status; and work-related variables including rank, sexual harassment, gender discrimination, salary equity, mentoring, teaching activities, service activities, publication for collaboration, and decision-making representation. Three hundred and twenty-eight counselor education faculty members across the United States participated in the study. Participants completed a mailed questionnaire including demographic information, quantitative survey questions, and related qualitative items designed to investigate work and life factors impacting the subjective work experiences of counselor educators. Chi-square analyses and analysis of qualitative responses related to four research hypotheses indicated that experience of the work environment for counselor educators is impacted by gender, tenure rank, age, and relationship status. Post-hoc analysis indicated that work experiences are also impacted by ethnicity, sexual orientation, and parenting status. Results also indicated a need for continuing attention to the effects of rank, salary equity, ...

Quantification of Anthropogenic and Natural Sources of Fine Particles in Houston, Texas Using Positive Matrix Factorization

Quantification of Anthropogenic and Natural Sources of Fine Particles in Houston, Texas Using Positive Matrix Factorization

Date: August 2012
Creator: Peña Sanchez, Carlos Alberto
Description: Texas, due to its geographical area, population, and economy is home to a variety of industrialized areas that have significant air quality problems. These urban areas are affected by elevated levels of fine particulate matter (PM2.5). The primary objective of this study was to identify and quantify local and regional sources of air pollution affecting the city of Houston, Texas. Positive Matrix Factorization (PMF) techniques were applied to observational datasets from two urban air quality monitoring sites in Houston from 2003 through 2008 in order to apportion sources of pollutants affecting the study region. Data from 68 species for Aldine and 91 for Deer Park were collected, evaluated, and revised to create concentration and uncertainty input files for the PMF2 and EPA PMF (PMF3) source apportionment models. A 11-sources solution for Aldine and 10-sources for Deer Park were identified as the optimal solutions with both models. The dominant contributors of fine particulate matter in these sites were found to be biomass burnings (2%-8.9%), secondary sulfates I (21.3%-7.6%) and II (38.8%-22.2%), crustal dust (8.9%-10.9%), industrial activities (10.9%-4.2%), traffic (23.1%-15.6%), secondary nitrates (4.4%-5.5%), fresh (1%-1.6%) and aged(5.1%-4.6%) sea salt and refineries (1.3%-0.6%), representing a strong case to confirm the high influence of ...

A Quantitative Analysis of the Relationship of a Non-traditional New Student Orientation in an Urban Community College with Student Retention and Grade Point Average Among Ethnic Groups

A Quantitative Analysis of the Relationship of a Non-traditional New Student Orientation in an Urban Community College with Student Retention and Grade Point Average Among Ethnic Groups

Date: December 2010
Creator: Martinez, Vesta Wheatley
Description: This quantitative study examined relationships of attending a new student orientation program related to student retention and academic success. A research group of 464 students of Tarrant County College Northwest, a community college campus in Fort Worth, Texas, who voluntarily attended a 2-hour pre-semester new student orientation program was compared to a group of 464 students on the same campus who did not attend the program. Comparisons were made with regard to retention and GPA. Ethnic ratios of both groups are 4% Black, 26% Hispanic, 66% White, and 4% other ethnicities. Chi square data analysis was utilized to determine if statistically significant differences relating to student retention existed between the groups. The independent t-test was used to compare means of calculated GPAs between groups. A one-way ANOVA was used to compare the means of GPAs for ethnic sub-groups. The total group and the Black sub-group showed statistically significant higher levels of second-semester retention (total group p = .018; Black sub-group p = .008) and higher calculated GPAs (total group p = .016; Black sub-group p = .019). No statistically significant results were found among Hispanic students.

A Quantitative and Qualitative Bacterial Analysis of Pecan Creek

A Quantitative and Qualitative Bacterial Analysis of Pecan Creek

Date: 1946
Creator: Cook, Vernice
Description: Since Pecan Creek receives sewage wastes from an obviously inadequate disposal system, it seemed possible that it could receive pathogenic bacteria. The fact that these might be present in numbers sufficient to cause epidemics, provided the proper natural vectors were present, stimulated an interest in and the pursuance of this study.
