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. …

Further Studies On Purification Of A Mannitol Binding Protein: Use Of Ph Gradients For Elution From Cation Exchange Resin, Kristyne Ann Baumgarten

Masters Theses

Studies on the purification of a mannitol binding protein (MBP) from Pseudomonas aeruginosa PAO were performed. Utilizing the alkaline isoelectric point (pi 8.3) of MBP, pH gradients were used to elute MBP from carboxymethylcellulose cation exchange resins. Purification of MBP was monitored by sodium dodecyl sulfate-polyacrylam ide gel electrophoresis (SDS-PAGE). Only one protein band was seen on SDS-PAGE from MBP fractions elutedat pH 7-8 and 8 .2. Although pH gradients appear to give good purification from cation exchange resins, these procedures lead to loss of MBP activity.

Hydrodynamic Character Of The Dundee Limestone In The Central Michigan Basin, Ann Carol Little

Masters Theses

The Middle Devonian Dundee Limestone underlies most of the Lower Peninsula of Michigan. A potentiometric surface constructed of the formation, utilizing pressure data was compared to local and regional structure, permeability trends, specific gravity of the brines, oil accumulations, and surficial topography.

The data were distributed mainly in the central basin area, with information becoming more sparse around the basin margins. This created difficulties in the determination of the extent of control imparted by each of the factors, in flow direction. Surficial topography, on a regional scale, is likely the most influential of the controls, with the Dundee Limestone brines …

The Effects Of Methylphenidate On The Learning And Performance Of A Child Diagnosed Addh, Kendra Leigh Heath

Masters Theses

The effects of methylphenidate (Ritalin) on the learning and performance of a child diagnosed Attention Deficit Disorder with Hyperactivity (ADDH) was evaluated using a repeated acquisition apparatus. A placebo and three dosages of methylphenidate were evaluated in both the learning and performance components of the experiment. Dosages tested included the subject's therapeutic dosage, a dosage 5 mg higher, and a dosage 5 mg lower. Methylphenidate produced no effect of consequence on the number of errors per session, suggesting that the medication neither impaired nor facilitated learning or performance at the range of dosages investigated. Data were also collected on social …

Reactive Counterion Surfactant Catalysis Of Hydroxamic Acid Hydrolysis With Perfluorooctanoic Acid, Mohamed El-Sayed Ayoub

Masters Theses

A micellar effect upon the rate of hydrolysis of hydroxamic acids in aqueous perfluorooctanoic acid has been demonstrated for hydroxamic acids with chain lengths of six , eight, and ten carbons. In this system the counterion, hydrogenion, is a catalyst. Typical rate constant-surfactant concentration profiles for micellar catalysis were obtained. The results for these hydrolyses are consistent with the pseudo-phase model for micellar effects.

In addition the Arrhenius activation energies were determined for the reaction of octanohydroxamic acid at surfactant concentrations above and below the critical micelle concentration of the surfactant. The activation energy is lower for reaction in the …

The Relationship Of Selection Criteria To Success In A Graduate Psychology Program, Cheri R. Stein

Masters Theses

The purpose of this study was to determine the predictive validity of the Graduate Record Examination Aptitude Test (GRE) for the Department of Psychology at Western Michigan University, Kalamazoo. Subjects were 138 psychology doctoral students.

Predictor variables included in the research were GRE-Verbal (GRE-V), GRE-Quantitative (GRE-Q), GRE-Total (GRE-T), Miller's Analogy Test (MAT), and undergraduate grade point average (UGPA). Criterion measures were trichotomous faculty ratings and points earned in three psychology courses.

GRE-V, GRE-Q, GRE-T, and MAT were significantly correlated with faculty ratings (p< .001), and the GRE scores were also significantly related to points earned in classes. Results indicated that MAT scores added no predictive value over and above GRE scores. GRE-T correlations were consistently equal or greater in magnitude than GRE-V and GRE-Q correlation coefficients. It was suggested that GRE-T scores alone be used in selection, with a cut-off point of 1100.

The Effects Of Reinforcement Magnitude On The Transfer Of Stimulus Control, L. Martin Grabijas

Masters Theses

Communication training for the developmentally disabled is becoming a vital component among residential training facilities. Such education necessarily entails the transfer of stimulus control from a prompt stimulus to a stimulus inherent in the task. The current study investigated the effects which different values of a reinforcer may have on the transfer of stimulus control. Three severely, mentally retarded adults were taught manual sign language, while two values of the reinforcer were varied according to two classes of response: preprompt and postprompt responding. A within subjects design was incorporated with a delayed prompting procedure in identifying the precise moment of …

The Use Of Repeated Acquisition As A Technique For Establishing A Behavioral Baseline With Victims Of Alzheimer's Disease, Michelle D. Stone

Masters Theses

Three subjects suspected as Alzheimer's Disease (AD) victims were trained on a behavioral chain of three sets of three poker chips, each set differing in color and position, to investigate subtle changes in learning and performance behaviors over time. For each session the subjects learned a new three-response sequence with a marked poker chip serving as the correct response for each set. A within-session learning curve resulted for all three subjects with the errors in the learning trial (LT) exceeding the errors for the performance trials (PT1 and PT2). Only Subject III demonstrated a stable pattern of learning, with the …

A Query Optimization Method For Use In A Generalized Database, Caroline D. Mautz

Masters Theses

Currently proposed methods for retrieval of records from a generalized file organization are not optimal, causing more I\0 retrievals than are necessary. This paper proposes another technique that has near optimal results and has a polynomial order of complexity.

The technique takes as input a query in disjunctive form, sorts the keys in the query in ascending order according to the number of records associated with them, then using a table much like a prime implicant table, systematically searches for a complete cover of the query conjuncts with a minimum total number of records associated with the keys that are …

Petrography, Diagenetic History, And Development Of Porosity In The Richfield Member Of The Lower Middle Devonian Lucas Formation, Northeast Isabella County, Central Michigan Basin, Kevin James Sullivan

Masters Theses

The Richfield Member of the lower Middle Devonian Lucas Formation is represented in the subsurface of northeast Isabella County, Michigan as a 180-foot-thick sequence of Interbedded limestone, dolomite and anhydrite. Richfield lithofacies within the study area reflect deposition in a complex patchwork mosaic of evaporative supratidal, in tertid al, shoal, and subtidal environments.

The present variations in Richfield porosities were caused almost entirely by post-depositlonal diagenetic changes. The carbonate units have undergone pervasive dolomltlzation of mud matrix, leaching of allochems, and extensive anhydrite void -fillin g . The best porosity developments are associated with partial to complete dolomitizatlon of the …

A Statistical Analysis Of The Lithic Material From The Zemaitis Site (200t68), Ottawa County, Michigan, Michael L. Murphy

Masters Theses

An analysis of the lith ic tools and a representative sample of debitage from the Zemaitis site is presented. The methodology employed in lith ic analysis is described with the goal of comparab ility with other studies. Based upon this comparison i t is suggested that the major occupation of the site was during the Middle Woodland Period and the site appears to have been occupied year-round. Because the Zemaitis site was undisturbed by modern agricultural techniques, special attention is given to the artifact distributions both vertically and horizontally across the site.

With the aid of various statistical models the …

An Investigation Of The Effect Of Daily Tests On The Retention Of Knowledge Of Malaysian Students In The Re-Orientation Program, Rokiah Mohamed

Masters Theses

Seventy Malaysian students participated in the 7-day Re-Orientation Program and were divided into two groups; 20 students were in Group 1, the group that took the daily tests and 50 students were in Group 2, the group that took the final examination only. The results of the final examination revealed a significant difference between the two groups, t (68) = 5.895, p< .05. The means of Groups 1 and 2 were 30.75 and 24.26 respectively. The correlations between the scores of the daily tests and the final examination scores were also statistically significant at p< .05 where n = 20. A post hoc analysis was done to further support the data. It is suggested that further research can be done using knowledge tests in programs that run for longer periods of time to improve students' retention of knowledge.

A Two-Dimensional, Three-Phase Reservoir Simulator Using The Impes Formulation, Ralph Ross Roesler

Masters Theses

"A numerical model for two dimensional, three-phase fluid flow has been developed using the IMPES formulation. Reservoir heterogeneities have been included, such as areal variations in porosity, permeability, thickness, and depth from a reference point. The model can also solve the problem of variable bubble points.

To check the accuracy of the model, a comparison was made with the Buckley-Leverett technique of predicting waterflood performance. The reservoir in the comparison is a 40 acre five spot with an initial gas saturation of 15 percent. The study shows that the two models are in good agreement, except for differences due to …
