Repeated Acquisition With Developmentally Disabled Adults: Some Methodological Improvements, Thomas M. Rueber

Masters Theses

This study obtained repeated-acquisition data from four developmentally disabled adults. The procedure was a refinement of one used earlier by Madsen (1988) and a comparison was made between the two. Verbal praise, edibles, and money were used to reinforce correct responding. In addition, an informal comparison was made between individual repeated-acquisition performance and IQ scores. The refinements of the Madsen procedure included: (1) using a 10-second timeout as the consequence of an error, (2) placing poker chips in die-cut holes, (3) using different colored construction paper backgrounds, (4) limiting each session to one sequence, (5) using percent correct responses as …

Reagan-Bush Drug Crusades: An Historical Perspective And Critique, Martin Randall Hill

Masters Theses

This study is a sociological analysis of anti-drug legislation during the last one hundred years within the United States. Anti-drug legislation is explored with regard to specific substances, as well as in general, and compared to anti-drug legislation of today. The conflict perspective was employed as an aid in understanding the occurrence of such phenomena as anti-drug legislation and drug wars. It becomes apparent that social problems or deviance, related to drug use, are more than simply a matter of someone transgressing. The laws are created in an effort to perpetuate the existence of groups with access to power and …

An Analysis Of Self-Report Delinquency: A Test Using An International Instrument, Linda Robyn

Masters Theses

This is part of an international pilot study on juvenile delinquency in the U. S. and six European countries. Research questions were designed based on using Hirschi’s (1969) theory of Social Control as a guide. Among the questions to be studied are the relationships between delinquency and single- and two-parent homes, participation in organized sports, and acts committed alone or with others. Interviews were conducted with 100 youths from 14- to 18-years of age. The population consisted of past and present students from junior high and high school in a mid-western city. The data were stratified into census tracts and …

Fractures In The Jacobsville Sandstone And The Precambrian “W” Rocks In Eastern Marquette County, Michigan, Leonard Paul Belliveau

Masters Theses

The major fracture systems in the Jacobsville sandstone likely originated by reverse faulting on the Keweenaw fault and by glacially produced thrusting. Fracture orientations, apertures, and spacings are uniform in the Jacobsville sandstone and Lighthouse Point member of the Mona Schist, and are variable in the Lower member of the Mona schist and Compeau Creek gneiss. Fracture sets in the Compeau Creek gneiss exist in domains separated by metadiabase dikes. The metadiabase dikes relieved the strain produced by the Penokean orogeny by fracturing. Fractures present in inclusions, quartz veins, metadiabase and diabase dikes can be used to temporally evaluate the …

Reinforcement Effects On The I.Q. Scores Of Institutionalized Children And Adults With Developmental Disabilities, Jody Robin Lewis

Masters Theses

Eighteen institutionalized school-age and adult subjects with severe/profound developmental disabilities were evaluated for the effects of self-selected reinforcement for correct responding on their I.Q. scores when tested with the Stanford-Binet Intelligence Scale (Terman & Merrill, 1960) or the Leiter International Performance Scale (Arthur, 1952). Subjects were tested under both standard and reinforcement conditions. The results indicated that overall, subjects when tested under reinforcement conditions showed a significant increase in mean I.Q. scores when compared with the same subjects tested one month previously under standard conditions. Several features of the data reveal intriguing results with regard to subjects and related preexisting …

The Effects Of Goal Setting And Supervisory Feedback On Staff Performance In A Human Service Setting, Michael D. Mack

Masters Theses

Goal setting and supervisory feedback were examined to determine their relative effects on the performance of direct care staff. The performance of five staff from a day treatment program for developmentally disabled adults was measured. The specific performance measure of interest was staff implementation rates of daily training programs with clients. The results demonstrated that adding performance feedback to goal setting had minimal impact on staff performance. Yet, goal setting alone as an initial technique was effective in improving the performance of staff. Unfortunately, the long-term effects of goal setting alone may be less desirable than these initial data indicate. …

Eta Photoproduction Via 2H(Γη)2H*, Yan Zhang

Masters Theses

The reaction H(γη)²H^* is studied using the impulse approximation. A recent fit to the H(γη)²H^* elementary amplitude is employed in the calculation. The n-p final state is described by Reid's soft core potentials. The calculation shows very different cross sections for the final isospin 0 and isospin 1 break-up channels. The S₁₁ resonance is demonstrated to dominate the eta cross sections in the 740 MeV photon laboratory energy region. Fermi motion in the deuteron does not significantly spread the effect of the S₁₁ . All these results demonstrate that the reaction H(γη) …

Reflection And Particulars: Does Casuistry Offer Us Stable Beliefs About Ethics?, David J. Zacker

Masters Theses

This enquiry suggests a solution to a challenge posed by Bernard Williams (1985) in Ethics and the Limits of Philosophy to develop a positive ethical theory that fulfills his guidelines. In particular, the theory is used to solve two problems: (1) reflection typically uproots and destroys ethical beliefs, and (2) modern ethical theories typically answer questions about ethics universally and ignore their practical characteristics.

Casuistry, as explained by Albert R. Jonsen and Stephen Toulmin (1988) in The Abuse of Casuistry: A History of Moral Reasoning, responds to Williams' challenge. To solve (1) casuistry must employ thick ethical concepts, ethical concepts …

Drug Problem And Social Change In Saudi Arabia: A Study Of The Attitude Of Saudi Students Studying In The U.S.A. Towards Drug Use In Saudi Arabia, Abdullah Yousef

Masters Theses

The main focus of this study is the relationship between level of income, level of education, length of stay in U.S.A., frequency of contact with foreigners, and level of religiosity on student attitudes towards smoking cigarettes and hashish, and drinking alcohol.

A sample of 110 students was randomly drawn from three areas: Kalamazoo, Ann Arbor, and Lansing, Michigan. Data were collected through administering a questionnaire.

Analysis of the data revealed the following: income, level of education, length of stay in the U.S., frequency of contact with foreigners, and level of religiosity were associated with student attitudes towards drug use.

The Debate On Lesbian Sadomasochism: A Discourse Analysis, Gudbjorg Ottosdottir

Masters Theses

This study examines an issue debated within the U.S. lesbian community since the mid-1970s, lesbian sadomasochism. The issue has been whether sadomasochism is consistent with lesbian feminism, a political ideology which has much shaped lesbian identity and community. The claims and counter-claims made about lesbian sadomasochism are analyzed, as are the underlying ideologies and their relationship to general lesbian political and cultural history. It is argued that the debate is the result of a limited subject position offered by lesbian feminism. The perspective of lesbian sadomasochists is seen as a call for a renewed lesbian feminist discourse. It is proposed …

Patterns Of Illicit Drug Use Among American High School Youth: An Examination For The Years 1976 And 1986, Dennis Rosado Malaret

Masters Theses

Previous studies have noted the importance of structural and demographic variables for the study of drug use among high school students. The present study focuses on the pattern and extent of legal and illegal drug use by high school seniors, by variables such as gender, race, religion, and academic achievement, among others.

This study evaluated the effectiveness of a feedback system developed to increase the productivity and job satisfaction of clerical staff in a university unit that admitted and audited students. Weekly and daily feedback were compared. Employees self-recorded the quantity and type of tasks completed throughout the study. In feedback condition 1, the supervisor delivered feedback once a week to two employees and everyday to three employees. In feedback condition 2, feedback frequencies were switched such that employees who first received weekly feedback received daily feedback, and employees who first received daily feedback received weekly feedback. Job satisfaction was measured before …

Comparison Of Body Assessment Using Bioelectrical Impedance And Skinfold Measurements In The Critically Ill, Elizabeth Mae Gohlke

Masters Theses

This investigation compared two body fat assessment techniques, skinfold thicknesses and bioelectrical impedance, in an elderly population. Ten healthy adults and ten critically ill adults, aged 55-93 years, were tested. The body fat measurements were taken over a two-week period. Electrolyte levels, sodium and potassium, and hydration status were monitored. Intraclass reliability coefficients were calculated using a repeated measures analysis design (ANOVA). Bioelectrical impedance was not found to be a reliable method for estimating body composition in this study; reliability coefficients were R =.83, R =.98, R =.83, and R =.32 for healthy males, healthy females, critically ill males, and …

Masters Theses

This study examines the drop-off recycling program in Knox County, Tennessee, in order to evaluate the convenience of the drop-off site locations. Measures of convenience were distance, level of recycling participation, and location of the site. Surveys were administered to 461 individuals participating in the program at the three Convenience Centers with drop-off recycling facilities. The spatial analysis compared the drop-off locations to the development patterns of the surrounding area.

The survey results indicate that more people are recycling now than before the beginning of the drop-off program. More than half of those surveyed recycle at least once a week …

State-Corporate Crime In The U.S. Nuclear Weapons Production Complex: A Case Study, David Kauzlarich

Masters Theses

The objectives of this research are (1) to identify the characteristics of the environmental law violations committed during the production of nuclear weapons, (2) to identify the historical forces and events which have contributed to those violations, and (3) to use data on the illegal acts of the nuclear weapons production complex to help adjudicate between a number of competing explanations of the causes of organizational crime.

This research, a qualitative, socio-historical case study, found that a historical and structural level of analysis is best equipped to explain the causes of the weapons production complex's criminality. The conclusion of this …

The Effects Of Peer Tutoring On A Direct Instruction Reading Program, Robert Schuyler Brooks

Masters Theses

This study evaluated the effectiveness of peer tutoring with a direct instruction reading program prior to teacher-directed instruction. Six upper level elementary students participated in the peer tutoring program and two students participated in a control group.

The findings from this study indicate that: (a) pre-exposure to direct instruction in reading lessons with peer tutoring improves student reading rate without increasing error rate, and (b) the instructional time for a teacher-directed lesson decreases when peer tutoring is a part of the reading routine. It was concluded that peer tutoring prior to teacher-directed instruction increases student reading rates without sacrificing accuracy …

Rose, Lily, Spring For Chamber Orchestra, Thomas M. Bourcier

Masters Theses

The compositional use of Guillaume de Machaut's rondeau Rose, liz, printemps (Rose, lily, spring) is intended to be a modern reflection of the social, religious, and political trends of fourteenth century Europe.

While the thirteenth century witnessed the perfecting of a universal philosophy that reconciled revelation and reason, the divine and the human, the religious and the political in one unbroken and harmonious order of thought, the fourteenth century perceived each arena of thought as independent in itself and not subject to the others.

Similarly, through isolation and independent use of Machaut's melodic and rhythmic motives in composition for chamber …

An Analysis Of Hydrogeologic Factors Affecting Aquifer Vulnerability In Southwestern Michigan, Steven E. Benton

Masters Theses

In southwestern Michigan aquifers are threatened by human activities. Parameter/factor weighting systems are used to rate aquifer vulnerability. Hydrogeologic factors affecting aquifer vulnerability were investigated in this study.

Well records, soil surveys, hydrogeologic reports, and partial chemical analyses were used to obtain data on the aquifers, soil types, glacial sediments, and types of contaminants. Data analysis included comparisons of means and medians, factor analysis, and Pearson and Spearman Correlation analysis.

The results indicate that the aquifers in Kalamazoo County are not protected. Depending on the type of glacial sediment, hydrogeologic factors that protect aquifers are clay thickness and the depth …

A Hydrogeochemical Characterization Of A Glacial-Drift Aquifer System In Southwest Michigan, Patrick G. Barrese

Masters Theses

A hydrogeochemical investigation of the Schoolcraft Aquifer, an unconfined, glacial-drift aquifer located in southwest Michigan, was undertaken to focus on three topics: (1) the geochemical definition of recharge and discharge zones both vertically and laterally along projected flow paths, (2) the description of the carbonate and redox chemical systems, and (3) groundwater degradation associated with excessive nitrate, ammonium, and chloride concentrations.

The results of the study were inconclusive in defining recharge and discharge zones; however, iron and alkalinity concentrations were identified as possible indices for recharge and discharge conditions. The carbonate analysis indicated that the aquifer is saturated with respect …

Inhibited Spontaneous Emission By Photonic Band Gaps In A Square Lattice Of Periodic Dielectric Medium, Abdullah Al-Ghamdi

Masters Theses

The concepts of band theory for electrons can be employed to describe the behavior of electromagnetic waves propagating in two-dimensional, periodic dielectric structures. These two-dimensional, periodic structures can produce photonic band gaps in which the spontaneous emission by atoms embedded in the structure is prohibited and as a result the performance of many semiconductor devices can be enhanced. The calculations are based on finding the eigenvalues of the algebraic equation for the frequencies of electromagnetic waves moving in a square lattice composed of square dielectric rods with different dielectric constants.

Micellar Catalysis Of Hydrolysis Of Substituted Hydroxamic Acids With Perfluorooctanoic Acid, Zhongyuan He

Masters Theses

The work demonstrated the effects of differently located and substituted phenyl groups, as well as aliphatic groups in the hydroxamic acids, on micellar catalysis with perfluorooctanoic acid as the reactive counterion surfactant in aqueous acetonitrile solution.

Kinetic rate constant-surfactant concentration profiles for the decano-, 2,5-dimethylphenylaceto-, 4-isopropylphenylaceto-, 4-phenylbutano-, and 6-phenyl-hexanohydroxamic acids were examined and analysis on the data obtained were reported.

The pseudo-phase ion exchange (PPIE) model has been satisfactorily applied to explain the observed micellar effects.

Further investigation into more appropriately substituted hydroxamic acids is suggested in order to obtain a more complete set of data and further evaluation.

Computer Aided Process Planning System For Generating Alternative Process Plans, Rao T. Gali

Masters Theses

Computer Aided Process Planning (CAPP) has a key role in Computer Integrated Manufacturing (CIM) as an interface between design and manufacturing. Current CAPP systems treat process planning as a static function, and always generate the same machine and process combinations. Thus, these CAPP systems are inadequate for advanced manufacturing facilities such as Flexible Manufacturing Systems (FMS). This thesis presents research conducted for the design and development of a CAPP system called Alternative Computer Aided Process Planning (A-CAPP) which generates alternative process plans by interacting with production planning and machine loading functions to satisfy system capacity constraints.

A-CAPP is a variant …

Temporal Contiguity As A Defining Feature Of The Terms Reinforcer And Discriminative Stimulus: A Survey Of Journal Editorial Staffs, Julie Ann Fillhard

Masters Theses

Behavior analysis is a science that requires a consistent set of terms to describe independent and dependent variables and the relations between them. However, a review of literature indicates that behavior analysis is plagued by terminological inconsistencies, even with such basic terms as reinforcer and discriminative stimulus.

In the present study, 193 journal editorial staff members were surveyed to determine the importance of temporal contiguity in defining the terms reinforcer and discriminative stimulus. Eighty-seven editors (45%) responded to the survey which described two hypothetical scenarios and contained a series of questions relevant to each.

The results of the study indicate …

Cocaine And Timing: Drug Effects Under A Mixed Fixed-Interval Extinction Schedule, Vincent O. Hodge

Masters Theses

The effects of cocaine hydrochloride (3.2-56.2 mg/kg) were determined in rats performing under a mixed fixed-interval 60-seconds extinction 120-seconds schedule of food delivery. Responses were recorded in successive 5-second bins. With the exception of the highest dose (56.2 mg/kg), cocaine did not significantly affect rate of responding under the fixed-interval component or extinction component, or the time of peak responding under the extinction component. The highest dose significantly reduced response rates and shifted the time of peak responding leftward to quicker and earlier moments. Results are discussed in terms of possible rate- and time-dependent effects of stimulant drugs.

Nonidentity Matching Training As A Supplement To The Audio-Visual Combination Test, Melissa Wilson

Masters Theses

The Audio-Visual Combination Test is an assessment tool developed by Kerr, Meyerson, and Flora (1977), and used by those working with developmentally disabled persons to assess learning-to-learn skills. The test measures motor, visual, and auditory discrimination learning.

The experimenter attempted to determine if there were an important step-visual nonidentity discrimination-between AVC subtests 4 and 5/6 of the test. Twelve developmentally disabled adults were tested with three different sets of tasks interposed between a revised subtest 4 and 5/6. Results showed that most subjects had greater difficulty with the visual nonidentity discrimination than with the auditory/visual discrimination, subtest 5/6. The results …

Double Ionization Of Helium By Intermediate To High Velocity He+ Projectiles, Jun Forest

Masters Theses

Ionization of helium target atoms by He⁺ projectiles colliding with helium at energies of 0.125 to 3.0 MeV/u is investigated. Cross sections for single and double ionization, and ratios o f double-to-single ionization are determined for each outgoing projectile charge state, and are compared to previous studies. For the lowest energies investigated, the ratios are consistent with the two-step mechanism in which the projectile interacts separately with each target electron. At the highest energies, the ratios reach nearly constant values indicating approach to the high velocity limit. At these high energies, however, the ratios are all higher than the …

Time Delay Neural Networks And Speech Recognition: Context Independence Of Stops In Different Vowel Environments, Gregory Andrew Makowski

Masters Theses

A series of speech recognition experiments was conducted to investigate time-dynamic speech recognition of stop consonants invariant of vowel environment using data from six talkers. The speech preprocessing was based on previous studies investigating acoustic characteristics which correlate to the place of articulation (Blumstein and Stevens 1979). The place of articulation features were statistically abstracted using four moments and the energy level of the speech sample.

Both statistical and neural network pattern recognition methods were used. Statistical methods included linear and quadratic discriminant functions, maximum likelihood estimator (MLE) and K-nearest neighbors (KNN). The neural network approach used was Time Delay …

The Effects Of Quality Contingent Extrinsic Rewards On Intrinsic Motivation, Kimberly Ann Filler O'Connor

Masters Theses

Although many studies have shown that performance-contingent rewards increase performance quantity, few have examined whether quality contingent rewards increase quality. One objective of the present study was to determine whether quality contingent rewards would improve quality.

A second, independent objective was to determine whether extrinsic quality contingent rewards would decrease a person's intrinsic interest in and quality performance of a task following termination of those rewards. To date, no other studies have examined the effects of quality contingent rewards on intrinsic interest and quality performance.

The results indicated that quality performance-contingent rewards do improve quality. Quality contingent rewards increased quality …

1-Nitronaphthalene Causes Ultrastructural Changes Primarily In Nonciliated Bronchiolar Epithelium Followed By Ciliated Epithelium In The Rat, John-Michael Sauer

Masters Theses

This study describes morphological changes in the lung at several time intervals following a single injection of 1-Nitronaphthalene (100 mg/kg intraperitoneal) in male Sprague-Dawley rats using transmission and scanning electron microscopy. Dilation of the smooth endoplasmic reticulum and mitochondrial distension in the nonciliated bronchiolar (Clara) cells was apparent as early as 1 hour after injection, while adjacent ciliated cell showed minimal changes. At 6 hours, when respiratory distress was apparent in the animals, Clara and ciliated cells exhibited chromatin clumping, loss of mitochondrial cristae and cytoplasmic vacuolization. Also at 6 hours, the interstitial area around the terminal bronchioles was infiltrated …
