Effects Of Capillarity On Dnapl Thickness In Wells And In Adjacent Sands, Timothy V. Adams

Masters Theses

Physical model experiments were used to investigate the behavior of dense non-aqueous phase liquids (DNAPLs) in various geologic media.

The objectives of the laboratory investigations were to (a) compare DNAPL thickness in wells to thickness in adjacent sands, (b) observe and interpret dyed DNAPL migration in unsaturated and saturated sands, and (c) study DNAPLs' effects on clay layers.

Two cylindrical glass columns fitted with various well screens were filled with sand, clay layers, water, and dyed DNAPLs in four experiments. Columns were packed with fine or coarse sand and clay layers. Coarse hydrophobic sand was also used.

At equilibrium, DNAPL …

A Comparison Of Functional Equivalence Training And Timeout Procedures In The Reduction Of Disruptive Behavior, Steven D . Goodman

Masters Theses

The use of nonaversive or aversive procedures continues to be debated regarding treatment of behavior problems of persons with developmental disabilities. This study compared the efficacy of a punishment and a nonaversive procedure in the reduction of problem behavior. The nonaversive technique involved the teaching of alternative, functionally equivalent, responses. Timeout was employed as the punishment procedure. The functional equivalence training included a functional analysis to identify the motivating conditions for the disruptive behavior of three boys with severe mental retardation. Treatment conditions were evaluated on rate of disruption, effects on learning trials, and time engaged in training. Results indicate …

A Modified Parallel Fault Simulator For Combinational Circuits, Shih-Ming Li

Masters Theses

The most commonly used model for fault analysis is called the "Stuck-At" model. With this model, a faulty gate input and/or output is modeled as Stuck-at-0 (s--a-0) or Stuck-at-1 (s-a-1). After a certain number of test vectors are applied to a network, the percentage fault coverage is computed. This computed value relates to the percentage of stuck-at faults detectable at the output. Various studies have been made to enhance the performance of fault simulators. In this paper, a modified parallel simulator MODPAR for combinational circuits is presented. A comparison of simulation results from MODPAR is made with that of SCIRTSS …

Purity Of Purpose: The Aesthetics Of Bernard Of Clairvaux Based On His Monastic Anthropology, Daniel Marcel La Corte

Masters Theses

Questions concerning Bernard of Clairvaux’s view of art and architecture have been answered primarily from his words on monastic art found in his work the Apologia. Some scholars have taken these statements out of context to their intended audience. Others have placed them firmly within the framework of his monastic vocation. More recently, scholars have analyzed the treatise in a broader context by using the Apologia to explore the role of art in the Middle Ages. None of these scholars question the fundamental motivation for Bernard’s view on art and the role it plays in the hierarchy of the …

Effects Of Phenobarbital In Combination With Phenytoin Or Valproic Acid On The Delayed-Matching-To-Sample Performance Of Pigeons, Catherine Ann Karas

Masters Theses

The present study examined the effects of phenobarbital (S, 10,20, and 40 mg/kg), phenytoin (2.5, 5, 7.5, and 15 mg/kg), and valproic acid (40, 60, 80, and 120 mg/kg), and those of phenobarbital (10 and 20 mg/kg) in combination with phenytoin (2.5,5, and 7.5 mg/kg) or valproic acid (40, 60, and 80 mg/kg), on the delayed-matching-to-sample performance of pigeons. In general, high doses of each individual drug reduced accuracy. Drug combinations also reduced accuracy relative to control values. Reductions in accuracy produced by drug combinations were very similar in magnitude to those predicted by a response-addition model of drug interaction.

Value-Orientations, Socialization And Social Mobility: A Replication And Conceptual Extension Of Kohn, Eric O. Johnson

Masters Theses

This thesis replicates and extends Kohn and associates' (Kohn, 1969; Kohn et al, 1986) research on the differing value orientations of the middle and working classes, self direction and conformity to authority, respectively. Using the findings that these values are reflected in child socialization, investigation was extended to those socially mobile from the working to middle class. Since parental resocialization of the mobile occurs over time, it is hypothesized that eldest children of the mobile will be socialized to working class values and successive children increasingly to middle class values. Examination of this process also informs about the class maintenance …

Political Perspectives In Encyclopedias: Portrayal Of The Nicaraguan Revolution, Brian B. Smith

Masters Theses

Encyclopedia text is most often presented as objective, factual, authoritatively documented truth. To examine this knowledge claim, this thesis analyzes the portrayal of the 1979 Nicaraguan revolution in editions of the four major U.S. encyclopedias. A qualitative content analysis is employed to determine the political perspectives present in encyclopedia coverage of the Nicaraguan revolution and the subsequent changes in Nicaraguan political economy brought about by that revolution.

The findings indicate that significant differences among and within the encyclopedias existed in the text analyzed. A variety of political perspectives were found to have influenced the content of the text, and to …

Improving The Performance Of Corporate Instructional Designers, Karolyn A. Smalley

Masters Theses

The purpose of this study was to determine to what extent the job aid developed by Brethower (1968) controlled instructional designers’ behavior so that they effectively and efficiently produced performance-based learning programs. This study consisted of developing and testing two iterations of the Analysis-Design Instructional Guide (job aid). Instructional designers who used either version of the job aid were able to meet a higher percentage of general criteria for performance-based learning programs than designers who did not. In addition, they took less time to develop programs than industry norms suggest. Even though the behavior of the designers was not completely …

The Effects Of Urbanization On A Portion Of The Portage Creek Watershed: A Case Study On Surface Water And Groundwater Quality, Susan E. Rezek

Masters Theses

The surface water and groundwater quality in the study area of the Portage Creek watershed was analyzed to determine the possible effects of urbanization. Dry weather and wet weather surface water and groundwater samples were collected from June 1986 to November 1986 at selected stations in the watershed.

Water samples were analyzed for 26 inorganic and organic parameters. Most concentrations were below analytic method detection limits. The analytical data indicate that sodium and chloride are the principal contaminants resulting from urbanization. The probable source of the contamination is deicing salt applied to the City of Portage, Michigan streets.

Overall, the …

A Study Of Periphyton, Sediment And Diatom Community Structure As Monitors Of Heavy Metal Pollution In The Embarras River And Brushy Fork, David L. Vaultonburg

Masters Theses

The purpose of this study was to evaluate periphyton (diatom) and sediment heavy metal content and diatom community structure as potential monitors of heavy metal pollution in the upper reaches of the Embarras River system. The study was initiated due to recent industrialization in the area which could potentially contribute to the present heavy metal burden of Brushy Fork and the Embarras River. These streams are already subject to agricultural runoff, wastewater plant effluent, landfill leachate and other miscellaneous urban and highway runoff. The Embarras River system drains an area of approximately 2800 square miles in 11 east-central Illinois counties …

How Potassium Affects Emergence Of Five Supersweet Corn (Zea Mays L. Var. Rugosa) Cultivars With Low Temperatures, Nombasa Tsengwa

Masters Theses

Supersweet types of sweet corn (Zea mays L. var rugosa) are sensitive to low temperature during emergence and thus have difficulty in establishing stands in early spring. This study investigated how banded potash affected establishment of five supersweet cultivars of sweet corn in fields and growth chambers.

In the field, sweet corn cultivars were planted near Urbana, Il on April 18 and July 22, 1991 with three levels of potash (0, 45 and 90 kg/ha) banded at planting. Several parameters of growth and development were measured approximately 2, 4 and 6 weeks after planting. No significant effect of potash was …

A Comparison Of Attendance And Self-Esteem At Assumption High School, Connie Lee Falconer

Masters Theses

Nonattendance has historically been a problem for teachers and administrators. Only recently has the effect of self-esteem and attendance been the focus of serious research. This study was conducted at Assumption High School, Assumption Community School District #9, Assumption, Illinois. The study encompassed those students in grades 9 through 12 for attendance purposes in the school year 1990-1991. Those students who were added or dropped during the given school year were not included in the study. Since this research involved some of the factors of ten associated with nonattendance of high school students, all of the students continuously enrolled from …

The Effectiveness Of Auditory Bombardment In The Remediation Of Phonological Processes, Lisa M. Gangloff

Masters Theses

Current research examining the efficacy of different stages of phonological remediation is limited to the use of minimal pairs and the integration of language therapy to assist children with accompanying language deficits. Auditory bombardment, however, although frequently used, has not been researched as to its effectiveness in the remediation of phonological processes. Auditory bombardment is currently being presented through word lists. This researcher suggests that a language-based bombardment, in the form of children’s stories, would aid in the reduction of phonological processes and the acquisition of language skills.

Six subjects were included in the research study. The subjects ranged in …

Mmpi Profiles Of Sexual Perpetrators, Steven G. Vaupel

Masters Theses

The purpose of this study was to compare MMPI scores of 60 men referred for assessment and/or counseling at community mental health facilities. No MMPI protocols were excluded due to elevated validity configurations (70T or above). Forty of the referrals were referred for suspected child sexual abuse. Twenty of the referrals admitted (Admitter) to sexually abusing a child at the time of referral and twenty did not admit (Nonadmitter) to sexually abusing a child when referred. A control group of the remaining twenty subjects were referred for various offenses, none of which included sexual offenses against children. Significant differences were …

The Facilitation Of Students With Learning Disabilities To Postsecondary Education By Secondary Special Educators, Victoria A. Stephans

Masters Theses

This descriptive research was conducted to collect data concerning the attitudes and policies about transition to postsecondary education by secondary special educators in the State of Illinois. A survey was sent to 208 secondary special educators representing the independent high school districts in the state. The survey measured three variables in relation to size of school: special educators' awareness of postsecondary educational opportunities, special educators' expectations for students labeled learning disabled to pursue postsecondary education, and current practices for serving high school students labeled learning disabled. The findings showed that there were more likenesses than differences in the transition attitudes …

Development Of Ruthenium Vinylbipyridine Modified Electrode Surfaces For Use In Chemiluminescence-Based Detection Systems, Matthew F. Piescinski

Masters Theses

Based upon the chemiluminescent properties of [Ru(bpy)₃]²⁺ and the proven analytical applications of that complex in the detection of easily reduced anions in solution, a chromatographic detection system was designed utilizing an immobilized form of the Ru(ll) complex. The objective was to create, by electropolymerization, a regenerative chemiluminescent surface on a working electrode. Reductive electropolymerization was accomplished by the use of a [Ru(bpy)₃]²⁺ analog containing the ligand vinylbipyridine. Two analogs, [Ru(vbpy)₃][PF₆]₂ and [Ru(phen)₂(vbpy)][PF₆]₂ were polymerized on platinum, glassy carbon and indium-doped tin oxide working …

The Effect Of Downhill Running Training On 200m And 2000m Running Performance, Jacquilyn L. Gallagher

Masters Theses

Downhill running as a method of training for improved running performance is an option which has rarely been explored. The purpose of this study was to explore the idea that downhill interval training may be an effective form of improving efficiency and thus, performance time, in 200m and 2000m level running by producing increases in both stride length (SL) and stride frequency (SF).

To test this hypothesis, twelve fit male subjects were divided into two training groups, downhill (D) and level (L), matched on the basis of a 2000m time trial performance and VO_2max. The dependant variables of …

Direct Immunofluorescence Detection Of Giardia Spp. In Selected Mammals In Central Illinois, Using Anti-Giardia Polyclonal And Monoclonal Antibodies, Jeanette Aba Ackon Brown

Masters Theses

Giardia species occur in many kinds of mammals, and some of these hosts have been postulated as potential reservoirs for human infections. A study was initiated in fall 1990 to determine the distribution and frequency of giardiasis in populations of selected wild animals in 12 counties in Illinois. Fecal samples from 64 white-tailed deer, 13 coyotes, 9 muskrats, 6 raccoons, and 5 badgers were examined for the presence of Giardia spp. and specifically for G. lamblia. Anti-Giardia lamblia cysts polyclonal (PAb) and monoclonal (MAb), FITC-labeled antibody solutions were used for the direct immunofluorescence detection of Giardia cysts in …

A Review Of The Literature On Self-Care Children: A Need For Empirical Studies, Stephanie L. Perry

Masters Theses

The term "self-care child'' refers to a young child who returns from school and remains at home unsupervised for an indefinite period until the parents arrive from work, or one who is alone before school in the mornings. In this paper, the emotional functioning, social functioning, and academic performance of self-care children were compared to adult-supervised children. Also, programs designed for self-care children were examined.

When examining the current literature on the self-care child regarding loneliness, anxiety and behavior problems, susceptibility to peer pressure, sexuality, social functioning, and academic performance, no significant differences were found between self-care and adult-supervised children. …

The Validity Of Studies That Test The Effectiveness Of Psychotherapy, Ian K. Isaacs

Masters Theses

This thesis is a review of the validity of studies on the effectiveness of psychotherapy. Ten randomly selected studies are examined to determine if the validity of the study was affected by threats to statistical conclusion, internal, construct, and external validity. All of the studies examined were published after 1985. The results indicate that validity of the research on the effectiveness of psychotherapy is affected by some threats to validity: History, Testing, and Selection bias, (ie. internal validity). In addition, external validity was affected by the lack of use of appropriate control group, lack of a description of the therapy …

Factors Affecting Parental Investment Strategies In Male Waterbugs, Scott Kight

Masters Theses

Male giant waterbugs (Belostoma flumineum Say) brood eggs oviposited on their dorsi by conspecific females. Preliminary observations indicate that viable egg pads are sometimes discarded before hatching. Theory predicts that such behavior should occur only if costs incurred by brooding exceed benefits of hatching the egg pad. The amount of paternal investment per pad should be similar for both large and small pad sizes, but as egg pads become smaller, investment per egg increases. Thus, smaller pads should be more likely to be discarded unhatched than larger ones. Similarly, egg pads containing inviable eggs should also be more frequently …

The Perpetual Journey: Jonathan Edwards' "Personal Narrative" And Benjamin Franklin's Autobiography, Pamela A. Masden

Masters Theses

Scholarly readers seem to have avoided a comparison of the writings of Jonathan Edwards (1703-58) and Benjamin Franklin (1706-90). Although they were born three years apart, they are rarely represented in anthologies as having been contemporaries, primarily because Edwards was a Puritan preacher and Franklin was an "Enlightenment" politician and inventor. However, when we disregard these critical constraints and assumptions, we find that as writers and thinkers, they have a great deal in common.

In my thesis, I have examined the autobiographies of these contemporary works: Edwards' "Personal Narrative" (c. 1739-42) and Franklin's Autobiography (1771-88). The theoretical approaches of Jane …

A Rhetorical Analysis Of The Preaching Of Robert Lee Russell, Ben F. Pennington

Masters Theses

Robert Lee Russell's pulpit oratory is analyzed through a review of the literature, personal interviews and critical study of three specific sermons. The consistency of idea content and effectiveness of the preaching is evaluated according to the concepts of rhetorical analysis delineated in Nilsen's (1957) Interpretive Funnction of the Critic. Robert Russell's concepts of man [existence], ideas [knowledge], and society [values] is examined through analysis of his sermons. The results of the analysis are compared to the literature on preaching, statements from interviews with him, and comments by leaders of his congregation. It is concluded that Russell is an …
