A Computer/Tutorial System Compared With A Workbook/Tutorial System For Presenting Instructional Material To At-Risk Elementary School Students, Vincent O. Hodge

Dissertations

Two different ways of presenting instructional material and reacting to students’ responses were compared. One, taking advantage of several features of multimedia instruction involved a desktop computer and various computer-presented consequences of correct and incorrect responses (largely chosen by the student). The other consisted in presenting the same instructional materials (the SRA primary curriculum) in a workbook form with tutors' comments and praise as the main form of response consequence. The two methods were compared with respect to various measures of student and system performance, including student accuracy (percent correct responses), types of errors, amount of correct response repetition (over-responding), …

A Comparison Of Reported Teacher Selection Practices Of Elementary Principals In Michigan To Recommended Selection Methods, John E. Jarpe

Dissertations

Teacher selection is a complex, critical school personnel function. School leaders in Michigan’s districts will be hiring more teachers as projected enrollment increases and pending teacher retirements combine to open teaching positions. This study examined the effectiveness of teacher selection practices as they compared to selection methods described in administrative textbooks, journal articles, and research studies.

Thirty-six Michigan elementary principals reported their school building and district selection procedures. Qualitative analysis focused on their transcribed responses to interview questions about the aspects of teacher selection. The principals represented public schools that combined varying grade levels of kindergarten through sixth grade.

The Influence Of Promise Keepers On Fathers’ Involvement With Their Children, Michael J. Walcheski

Dissertations

This study explores the influence of Promise Keepers (PK) on fathers’ involvement with their children. The large numbers o f men involved with PK and the anecdotal success of fathers and their families have created considerable dialogue in the popular press. However, there have been no empirical studies to date that contribute data about the influence of PK on father involvement.

The conceptual framework informing this study combined father involvement and postmodern feminist perspectives. A father involvement perspective emphasizes fathers’ presence, their capability and strengths, the moral dimension to fathers’ responsibility for their children, and factors that establish responsible fathering. …

Removal Of Volatile Organic Compound (Voc) Vapors In Biotrickling Filters : Process Modeling And Validation With Chlorinated Aromatic Compounds, Christos J. Mpanias

Dissertations

This study dealt with the removal of vapors of volatile organic compounds from airstreams in biotrickling filters (BTFs). A detailed general model was developed for describing the process under steady-state conditions. The model accounts for mass transfer between phases (air, liquid, biofilm) and biodegradation of pollutants in the biofilm. It also accounts for potential kinetic interactions among pollutants as well as potential process limitations by oxygen availability.

The general model was experimentally validated using mono-chlorobenzene (m-CB) and ortho-dichlorobenzene (o-DCB) as model compounds either alone or in mixture with each other. Before BTF experiments were undertaken, a systematic kinetic study was …

Modelling Of In-Situ Bioremediation With Emphasis On Inhibitory Kinetics And Biomass Growth, Dilip Kumar Mandal

Dissertations

This thesis was motivated by the need for better engineering tools to predict the extent of contaminant plume migration in the saturated zone. The principal result was a mathematical model analogous to a catalytic packed-bed reactor, in which the subsurface was considered to be composed (conceptually) of soil aggregates (the "catalyst" particles, in which biodegradation, diffusion, and sorption take place), and a mobile phase (groundwater) passing around the aggregates, in which convection, axial diffusion, and mass transfer from the aggregates take place.

The modelling emphasis was on a more detailed exposition of the biokinetics of the system (including an inhibitory …

This first person, autobiographical account of one American citizen’s nine-week experience covering two years in the Republic of Armenia answers the question, aIs it possible to become resocialized in a foreign culture?’ Employing the experimental writing method called personal experience narrative, the author uses personal journal accounts and autobiographical stories as primary data to demonstrate his movement from ’modem tourist’ (MacCannell, 1976; 1992) to resocialized individual and provide a rich and detailed description of the Armenian homeland undergoing significant social changes after the collapse of the Soviet Union in 1991.

This study offers a model of socialization called ’life-learning’ to …

Observing The Spirit Of Resilience: The Relationship Between Life Experiences And Success In Higher Education For African-American Students, Cheryl Getz Edd

Dissertations

Some African American students with challenging early life experiences appear vulnerable to failure in higher education. This vulnerability may be exacerbated when educators fail to recognize the relationship between the life experiences of African American students and their academic performance and college success. African American students are challenged further as they attempt to successfully adjust to collegiate environments which often do not validate them or their experiences. The primary purpose of this study is to investigate this challenge with selected African American students, to learn about how the life experiences of African American students can enhance their success in higher …

Biodegradation Of Pah Contaminated Soil And Sludge Using Non-Ionic Surfactants, Seema Narula

Dissertations

Polycyclic aromatic hydrocarbons (PAHs) are one of the most prevalent environmental pollutants contaminating a large number of industrial and Superfund sites. Low solubility and sorption to solid surfaces limit biodegradation rates of PAHs in the environment. Bioremediation of these compounds have been previously tested with partial success. In the present study, aerobic biodegradation of three PAHs (fluorene, phenanthrene, and pyrene) has been studied in shaker flasks, batch fermenter, and bioslurry reactor, in the presence of non-ionic surfactants. A mixed bacterial culture derived from both a refinery sludge and an activated sludge was used as the seed population in the degradation …

Effects Of Surfactants And Fenton's Reagents On Extraction And Destruction Of Phenanthrene In Spiked Sand, Ming-Chin Chang

Dissertations

In this study, surfactants and Fenton's reagents (Fe(II) and H₂0₂) ere proposed to solve contaminated site problems in situ on a lab scale. Phenanthrene is a simple PAHs (polynuclear aromatic hydrocarbons). The phenanthrene spiked ottawa sand simulated contaminated soil. HPLC was used for phenanthrene analysis because it provided excellent separation and no interference. Six surfactants (including nonionic and ionic) were tested. The operating conditions were optimized based on process and economic considerations such as reaction time, mixing speed, concentrations of surfactants and concentrations of Fenton's reagents. Surfactants could effectively dissolve phenanthrene from the spiked sand. In …

Storytelling In Project Heart To Heart: A Means To Bridge Generational Gap In Post-1965 Filipino Immigrant Families, Juanita Toledo Santos Nacu Edd

Dissertations

As we share our experiences with others, we also explore its meaning to ourselves and to whomever it is being shared with. This is how stories are told. Most families usually develop a body of stories that is passed on from one generation to the next generation. These stories are used to preserve the family member's identity, history, and values. The stories touch not only our past experiences, but also influences our present and links it to the future. This study explored the Filipino American families' experiences of storytelling as a means of bridging together past, present, and future experiences …

Voices Against Discrimination And Exclusion: Latino School Leaders' Narratives For Change, Jaime J. Romo Edd

Dissertations

Many scholars, practitioners, and policy makers know very little about individual Latino administrators' cultural and professional experiences, responses to discrimination, and patterns or institutional conditions which relate to K-12 ethnic minority administrators' success. Moreover, many are also unaware that as ethnic diversity increases, the relative proportion of minority administrators, many of whom could be role models, shrinks. Once we can recognize this as seeds for inequity in society, we might be able to consider the ways in which our educational institution reinforces or counters societal inequities. By specifically exploring Latino administrators' experiences, because of the large Latino California presence, we …
