The Effects Of Xanthine And Adenosine Analogs On Rat Pup Diaphragmatic Contractility, Liam C. Farrell

Masters Theses

Methylxanthines are commonly used in the treatment of respiratory disorders such as asthma, apnea of prematurity and Cheyne-Stokes respiration. Recently, certain methylxanthines have been found to potentiate the contraction of the diaphragm and increase contraction strength of the fatigued diaphragm. The mechanism of action of the methylxanthines is unknown. Three theories have been proposed but each has its supportive and negative points. One theory is that methylxanthines inhibit cyclic AMP phosphodiesterase (PDE) which facilitates contraction by increasing cyclic AMP levels in the cell. Another theory is that methylxanthines antagonize adenosine, thus blocking the adenosine-induced inhibition of contraction. The third theory …

Isolation And Partial Characterization Of Serogroup Specific Antigens From Bradyrhizobium Japonicum 61a123, Miguel Eduardo Carrion

Masters Theses

Serogroup specific antigens of Bradyrhizobium japonicum 61A123 were isolated using an immunochemical assay. Bacterial antigens were isolated by phenol-water extraction. These antigens were detected by inhibition of an enzyme linked immunosorbant assay (ELISA). Low pressure chromatography and digestion with proteinase K served to purify the antigens. Chemical composition was determined by gas chromatography (GC), mass spectrometry (MS), and colorimetric assays. The antigens were also characterized by sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis, and immunological properties determined by ELISA. These antigens were shown to be lipopolysaccharides (LPSs) containing fucose, a 2-amino-2,6-dideoxy hexose (unidentified), glucose and mannose as the major sugars, along …

The Effects Of Educational Environments Upon The Academic Achievement Of Students Identified As Exceptional, Janet Y. Koch

Masters Theses

The effect of classroom setting upon the academic achievement of students identified as exceptional is an issue worthy of exploration. A plethora of research data tends to show that segregated settings are more effective for individuals who are moderately to severely handicapped in intellectual or physical functioning, whereas integrated settings are more favorable toward those who are mildly handicapped (e.g., learning disabled or behavior disordered, for instance). Numerous variables in the different delivery systems make it rather difficult for the research to pinpoint which type of setting contributes best to a child's learning.

Research in the past has put considerable …

A Weaverian Analysis Of The Secular Humanism/Christianity Arguments, Colleen Deborah Ryan

Masters Theses

Since the Renaissance, the unclearly defined movement known as "Humanism" has been a part of society. However, it is only recently that the movement itself has caused significant controversy. What is responsible for this sudden outbreak of humanism hysteria? Is it even to be classified as a problem? To many, especially the Catholic church and many fundamentalist groups, it presents an overt threat.

A vital area of controversy centers around education and the fight between a religious-based curriculum and the more recent secular studies. The issues, it appears, are often obscured by the rhetoric. Indeed, Karl Wallace sees rhetoric as …

Services In The State Of Illinois For Students Identified As Behavior Disordered, Christi D. Hipple

Masters Theses

Problems exist which interfer with the ability to provide consistent and appropriate educational services to students identified as behavior disordered. These problems involve the inability to provide an educationally relevant label and definition on the federal level, the inability to define and describe the types of services or interventions beneficial to these students and the inability of some districts to comply with minimum federal regulations due to demographic variables.

Family Problems In The Background Of Mental Health Professionals, Linda Elaine Mccarter

Masters Theses

It has been proposed by some that students choose to study in mental health related fields in an effort to find solutions for their own personal emotional or family problems. Some believe that those who assumed or were assigned a family role of the good or parentified child (a role which requires that the needs of others be placed ahead of one's own) are over-represented among mental health professionals. Others contend that there are no significant differences in family background between psychotherapists and other individuals with a similar level of education. Little empirical investigation has addressed these issues. Studies which …

Image And Meaning In The Floral Borders Of The Hours Of Catherine Of Cleves, Elizabeth R. Schaeffer

Masters Theses

The Book of Hours of Catherine of Cleves, produced in

the Netherlands c. 1440-45, is one of the most beautiful and

complex illuminated manuscripts of the late Middle Ages.

The Master's originality in his symbolic use of floral

images in the borders of the manuscript is remarkable, yet

little study has been made of this subject. The meaning of

these floral images is, however, important to a complete

understanding of the illumination of the manuscript.

Using a set of criteria based on the tenets of the

Devotie Moderna, a philosophy strong in the Netherlands at

the time, I show that …

Effects Of Cued Intertrial Intervals On Response Latency In Pigeons, Franklin Paul Whitley

Masters Theses

Six White Carneaux pigeons were exposed to fixed-ratio schedule components in a systematic replication of a study by Michael et al. (1981). Separation between median latencies for the two schedule components was demonstrated consistently, reproducing the general features of that research. In a subsequent manipulation, differential stimulus conditions were introduced into the intertrial intervals preceding onset of schedule components in an effort to enhance the likelihood that differential "waiting behaviors" would develop. Two subjects demonstrated a clear decrease in the magnitude of the latency splits following introduction of the cued ITI condition, while other subjects evidenced a similar but less …

An Ethnographic Study Of Punk Rock In Western Michigan: Identity In A Youth Subculture, Robert P. Pomeroy

Masters Theses

This thesis presents an ethnosemantic analysis of the punk rock subculture of western Michigan. Assertion of personal identity is demonstrated to be the underlying principle which organizes punk terminology for their music, cultural environment, and members of the subcultures. An analysis of punk song lyrics, visual style, and verbal style demonstrates that this assertion of identity is accomplished through opposition to the dominant American culture. Punk rock can then be understood as a subculture of cultural rebellion which allows its members to assert their individuality through violation of culturally accepted aesthetic values.

Horizontal Fragmentation And Allocation In A Distributed Database For Cost Minimization With Reliability And Space Constraints, Elmo Loren Ivey

Masters Theses

In this paper a method for horizontal fragmentation of a relational database is presented. A method is given for calculating the benefit or cost savings obtained by allocating a given fragment to a site, independently for each site.

To obtain optimal benefit each fragment is allocated to all sites where there is a positive benefit. This may result in the allocation of some fragments to multiple sites.

Finally a method is given for removing or reallocating certain fragments from sites with insufficient storage. Also, a method is given for allocating fragments to multiple sites to meet constraints on the required …

A Dynamic Study Of The Effect Of Cationic Starch Molecular Weight And Charge On Filler And Fines Flocculation, Deflocculation, And Reflocculation, Bob Shian-Hou Ching

Masters Theses

A modified laboratory instrument was used to dynamically monitor the flocculation of fines and filler under various shear conditions on the "seconds" basis. A three-way factorial design and ANOVA were used to evaluate the significance of cationio starch molecular weight and charge in affecting fines and filler flocculation, deflocculation, and reflocculation. The reduction of molecular weight under high shear was suggested by the results. Both main effects and interaction effects of charge and molecular weight were important in determining flocculation. Charge was the only significant factor for the reflocculation process. Molecular weight was more important than charge in imparting shear …

Effects Of Feedback And Incentives On The Use Of Academic Skills, Jose E. Candia

Masters Theses

This research investigates the notion that the combination of feedback and incentives are essential components for the maintenance of effective academic skills with undergraduate students on academic probation. This notion is in contradiction to the assumption underlying remedial activities in most universities, where it is assumed that once the students have acquired the skills through workshops or texts they will continue to use them.

The use of the academic skills of lecture note-taking, comprehensive reading, and critical reading was studied with three undergraduate students. That use was measured prior to the intervention, during workshops of training, when feedback alone was …

Detection Of Deception In The Laboratory As A Function Of Motivation And Set Size, Daniel Mark Tuckett

Masters Theses

The purpose of this study was to determine the validity of the polygraph in a controlled laboratory setting. The Guilty Knowledge Test (GKT) was the procedure employed in conjunction with the galvanic skin subjects over the two trial each. Overall the polygrapher was correct 44 times, out of 80 trials. This number of detections exceeded chance (p<.001) levels. The manipulation of subject motivation with a monetary reward increased detection rates significantly (p<.05) in comparison to those offered money. With each subject being tested over two trials, there appears to be a habituation effect as indicated by a decrease in detection from trial one to trial two. The relationship fell slightly short of significance at the (p< .05) level. In general the level of the subject motivation may play a major role in the detection of subjects who attempt deceit.

Analysis Of The Effects Of Goal And Feedback Specificity On Subsequent Task Performance, Gregory Mark Van Dahm

Masters Theses

The effects of goal and feedback specifically on subsequent task performance were examined to text the hypothesis that specific goals and feedback facilitate performance to a greater degree than general goals and feedback (Ilgen, Fisher, & Taylor, 1979). Ten subjects, in each of the four conditions, were assigned one of two levels of goal specificity and feedback specificity and were then required to perform a simple assembly and sorting task utilizing multiple size and color fasteners. No significance was discovered between correctly assembled and sorted products of the four groups although there was a general trend in the hypothesized direction. …

Use Of A Changeover Key To Train Serial Learning In The Pigeon, Rhoda Kay Yutzy-Ryan

Masters Theses

Three pigeons were presented with a serial learning task involving a sequence of three colors: yellow, green and red. The colors appeared on a lit key one at a time in random order. The pigeons were required to peck the colors in the correct order and to use a second lit key (the changeover key) to change the color when it was incorrect. The data show that the pigeons were able to learn the task and generalize to novel arrays at a high level of accuracy. This extends the findings on serial learning with pigeons to a type of sequence …
