Do Caucasian And African American Students Have Different Learning Styles?, Robin J. Black-Vannoy

Masters Theses

This study explored whether African American and Caucasian students have different learning styles. It specifically examined differences in preferred modes of information processing and instruction. Participants in the study completed the Dunn and Dunn Learning Style Inventory and the Kolb Learning Style Inventory. Subsequent analyses revealed that there were no significant differences in how African American and Caucasian students choose to process information for learning. However, there were some significant differences in preferred modes of instruction. African American students were more likely to prefer noisier and warmer learning environments, to snack while learning, and to learn in the late morning. …

Novel N-Body Orbits For Constrained Potentials Including The Unusual Figure Eight Three Body Orbit, Jan M. Dudzik

Masters Theses

Recently new n-body planar orbits have been discovered which are known as choreographies. These orbits correspond to small n, generally n<20, and exhibit unexpected patterns with respect to given initial conditions. Here we shall examine numerical solutions to the three-body problem and the restricted three-body problem for three body potentials that are the sum of three two-body potentials. Then for an everywhere attractive three body potential with non-collinear and collision-less orbits with a strictly monotone decreasing potential function there exist bound states that are not chaotic that are choreographies. For the right initial conditions these orbits can be mapped numerically and visualized. We will display a number of these cases corresponding to the three body problem, restricted three body problem, the chaotic restricted three body problem and the new figure eight bound state choreography for the Kazalov potential orbits to exhibit some of their special features and to take note of a number of open questions dealing with simple orbital problems.

Low Stress Algorithms For Children With Difficulty In Mathematics, Amanda B. Boyer

Masters Theses

The purpose of this research was to examine the effectiveness of low-stress algorithms with third and fourth grade students who struggle with mathematics. It is important to study mathematics interventions because math is a neglected area of research (Gersten & Chard, 1999). This research examined the effectiveness of low-stress addition and subtraction instruction for low-achieving students compared to a control group of students receiving traditional instruction in the regular classroom. Additionally, half of the students in the experimental group (low-stress) self-monitored the number of problems they correctly completed. Results indicate that low-stress addition did not result in an increased number …

A Similarity Based Concordance Approach To Word Sense Disambiguation, Ramakrishnan B. Guru

Masters Theses

This study attempts to solve the problem of Word Sense Disambiguation using a combination of statistical, probabilistic and word matching algorithms. These algorithms consider that words and sentences have some hidden similarities and that the polysemous words in any context should be assigned to a sense after each execution of the algorithm. The algorithm was tested with sufficient sample data and the efficiency of the disambiguation performance has proven to increase significantly after the inclusion of the concordance methodology.

Distinct Group Differences And Discriminant Validity Of The Adjustment Scales For Children And Adolescents: Attention Deficit Hyperactive Disorder Versus Conduct Disorder, James Richard White

An Analysis Of Mentorship In Michigan Police Agencies, Jeffrey G. Swanson

Masters Theses

The purpose of this research is to investigate how newer police officers are familiarized into their agency with respect to the manner in which they were trained and mentored. The concept of mentoring programs has been highly successful in the private and business sectors for many years. Since the concept of formal mentoring programs in law enforcement is largely limited to date, this study incorporates research in several other disciplines, to determine if there may be a corollary regarding law enforcement and other disciplines, and if so, to what degree mentoring exists among patrol officers. A survey was distributed to …

Proportional Representation Electoral Systems And Indigenous Representation: Case Studies From Bolivia, Ecuador, And Peru, Arne Romanowski

Masters Theses

The central question of this analysis is how the proportional representation electoral systems in Bolivia, Ecuador, and Peru are linked to indigenous political representation. I argue that the electoral system and its affect on party structures and party development are part of the reason why indigenous people, who make up a great part of the population in these three countries, are chronically under-represented in their political systems. In these case studies, district and national level data from the two most recent elections for the national legislatures was analyzed in terms of indigenous party formation and success. The study concludes that …

Considering Instructional Time And Comprehension Rate When Evaluating The Effectiveness Of Reading Interventions In Classrooms, Kelly E. Thomason

Masters Theses

The purpose of this investigation was to replicate and extend research done by Daly et al. (1998), which focused on the functional analysis of academic problems. This research examined comprehension and amount of instructional time as dependent variables to determine the effectiveness and efficiency of reading interventions (repeated reading, contingent reinforcement for rapid reading, and listening passage preview). Results suggest that when evaluating increases in oral reading fluency (words read correct per minute), each participant obtained greatest gains using different combinations of interventions. However, when examining instructional time specifically, it becomes clear that the contingent reinforcement and listening passage preview …

Voices Of First And Second Generation College Students: Reasons For Enrolling In Graduate Education, Rodney S. Ranes

Masters Theses

The purpose of the present study was to identify characteristics and choices that have assisted first-generation students in attaining a baccalaureate degree and enrolling in graduate study. Previous research identified academic preparation, institutional choice, and family experiences as areas that influenced first-generation students. Attrition and retention were also explored, as well as issues related to graduate enrollment. A selected sample of four first-generation and four second-generation participants were interviewed using qualitative methods (Lincoln & Guba, 1985) regarding academic preparation, family culture, prior institutional choice, and influential mentors. Interview findings were triangulated and themes and issues identified. Results showed that second-generation …

The Dependence Of The Overall Drying Time And Product Quality Of A Lyophilization Process On The Relative Position Of Vials On A Tray With Tray Sides And Without Tray Sides For Different Heat Input Control Policies, Kian Hui Gan

Masters Theses

"The dynamic behavior of the primary and secondary drying stages of the lyophilization process were studied when (a) single vials located at different positions on the tray were individually being dried, and (b) the vials on the tray are arranged in clusters of square and hexagonal arrays and all the vials on the tray are simultaneously being dried. For both cases (a) and (b), fast drying times and relatively more uniform distributions of temperature and concentration of bound water at the end of the secondary drying stage are obtained by heat input control that runs the lyophilization process close to …

Discerning Attributes Which Stimulate Performance In Quality Improvement Teams, Dwan Lamar Prude

"Total quality management (TQM) can be summed up as people and the way they work. One key element of the philosophies of TQM is the heavy emphasis on utilizing quality improvement teams (QITs) and quality tools to effectively create high performance organizations. Specifically, this investigation asks the following questions: 1) What are the key attributes that contribute to performance in QITs? 2) What is the relationship between team communication and QIT performance? 3) What is the relationship between the number of quality tools utilized in a team and QIT performance? Participants for this study were 101 students from the University …

Innovative Contracting Prequalification/Selection Model Using Analytical Hierarchy Process (Ahp), Saad J. Zidan

Masters Theses

Design-Build, Cost-Plus-Time, and warranty are the three innovative contracting methods that the Federal Highway Administration (FHWA) decided to fund. FHWA allowed the usage of these methods in federally funded projects if this will result in reducing time, improving quality, and saving tax payers' money. Prequalification is recognized as the best way of assuring that contractors do have the required qualifications to deliver projects successfully. Prequalification is even more critical when low-bid selection method is used with any of the innovative contracting, since incompetent contractors may get awarded for low-bids that are not based on valid assumptions.

This study presents a …

Capillary Electrophoretic Separations Of Metal Ions, Elena Hofman

Masters Theses

Transition-metal (Zn(II), Co(II), Ni(II) and Cu(II)) ion separation was studied using 8-hydroxyquinoline-5-sulfonic acid and 2-methyl-8-hydroxyquinoline ligands with surfactants (cationic and anionic) by capillary electrophoresis under a variety of conditions (like pH, ionic strength, voltage and ion, ligand and surfactant amounts) and has debuted a clear separation mechanism. With cationic surfactants, ligands compete with capillary surface silanols for the metal ions; with anionic surfactants, ligands, silanols and micelles compete.

An empirical parameter, K_e, (electrophoretic-mobilities based) rationalizing the separation was proposed, experimentally analyzed and supported; it provides a silanol group per cm² value of the capillary surface, an equilibrium …

Classifying Forest Composition Using Fractal Dimension As An Index Of Image Texture, Fitria Latifah Wahid

Masters Theses

In this study, Landsat imagery from June (summer) and October (autumn senescence) 2000 of the area of Fort Custer Training Center in Kalamazoo and Calhoun Counties, Michigan, were analyzed for forest classification accuracies. The use of fractal analysis to improve forest classification, particularly to distinguish among northern hardwood species, was examined. Using moving windows with different sizes, measurement of local fractal dimension and spatial autocorrelation (Moran's I) were performed on the NDVIs and the panchromatic images. The measurement products were combined with Landsat TM bands as additional layers in supervised maximum- Iikelihood multispectral classifications. The accuracy for multispectral classification of …

Geophysical Characterization Of A Former Refinery Site, Kalamazoo, Michigan, Baraka Damas Kinabo

Masters Theses

Lakeside, a former refinery site, in Kalamazoo, Michigan, is contaminated with hydrocarbon products. The contamination resulted from the refining and storage activities that took place at the site for over 50 years. The contamination is scattered in isolated pockets.

In an attempt to better define the contamination zones and therefore assist the remediation efforts, this study uses shallow geophysical methods including Electromagnetic induction using the EM 31 system, Magnetic, Ground Penetrating Radar (GPR), and Resistivity methods. The hand auger was used to further characterize some EM 31 anomalies. The EM 31 conductivity results show elevated values resulting from the biodegradation …

A Comparative Study Of Photomultiplier Tubes And Charge Coupled Devices In Glow Discharge-Optical Emission Spectrometry, Robert James Broadwater

Masters Theses

This Masters Thesis compared two glow discharge-optical emission spectrometers designed around two different types of detectors: the photomultiplier tube (PMT) and the charge-coupled device (CCD). The two instruments compared were the LECO SA2000 (PMT-based) and the LECO GDS500a (CCD-based). Detection limit, dynamic range, precision, accuracy, and drift were determined to compare the detection systems between 165 and 450nm.

The PMT-based system outperformed the CCD-based system in all five of the categories studied based on the initial protocol. However, it was shown that improvements could be made in four of the five categories studied by exploiting the CCDs ability to monitor …

Laboratory Testing Of Select Geotextiles As Biointrusion Barriers And Sediment Filters, David R. Beck

Masters Theses

It has been proposed that placing a geotextile over sediments with adsorbed contaminants can prevent bioaccumulation of the contaminants in larger animals by isolating the benthic organisms living within these sediments from fish. In conjunction with a field study carried out at Gull Creek, a laboratory study testing two geotextiles as biointrusion barriers and sediment filters was conducted.

Constant-head permeameters were run for seven days using cores from the field study area with a geotextile placed over the cores. For biointrusion barrier tests, medium sand was placed over the geotextile and spiked with nutrients. Following each trial, benthic organisms in …

Effects Of Computer Troubleshooting On Elementary Students' Problem Solving Skills, Anne Todd Ottenbreit

Masters Theses

The lack problem solving skills exhibited by students has generated concerns at national and state levels of education (Coleman, King, and Ruth, 2001). If the educational technology curriculum involved computer troubleshooting, students could possibly increase their problem solving abilities. Because computer troubleshooting follows similar procedures to problem solving, there is possibility of an educational transfer and could be easily included into the educational technology curriculum. The purpose of the research study was to discover if the computer troubleshooting curriculum designed by the researcher affected the elementary students' problem solving abilities. Technology education at the elementary level includes keyboarding and 'practice …

Evaluation Of The Distribution Of Taguchi's Signal-To-Noise Ratio And The Effectiveness Of The Signal-To-Noise Ratio For Detecting Changes In The Mean And/Or Variance, Jinsuk Lee

Masters Theses

The concept of parameter design developed by Taguchi to achieve robust engineering is widely promoted in industry as a means to design a product whose output is largely immune to noise in the system. Taguchi has used the signal-to-noise (S/N) ratio to summarize measures over the noise factor settings at the parameter design and to allow control of the experiment.

The objectives of this investigation are: 1) to infer distributions of S/N ratios (lower-the-better S/N, higher-the-better S/N, and nominal-the-best SIN), and 2) to determine the effectiveness of the S/N ratio as a means for identifying changes in the mean and …

Mindful Communication In A Crisis: Communication Behaviors Of Shared Mindfulness And Effective Pilot Decision Outcomes In Crisis Situations, Janice L. Krieger

Masters Theses

Despite the high reliability of current aeronautical technology and safety improvements, human error continues to be a factor in 60-80% of all aviation mishaps. Training to diminish potential errors is often based on analysis of faulty procedures, or lack of procedures without a systemic view including human factors such as communication, decision-making and interaction dynamics. This research explores the existence of the psychological construct of shared mindfulness and examines how it is communicatively constructed and enacted in a high reliability environment such as the aviation industry. The present qualitative study examines shared mindfulness in 10 aviation student dyads in a …

Application Of Geochemical Fingerprinting And Isotopes To Identity Landfill Gas Impacts To Groundwater, Eric E. Wallis

Masters Theses

Volatile organic compounds (VOCs) are detected in two groundwater monitoring wells (MW-60 and MW-62S) located along the northern, downgradient property line of the McGill Road Landfill (MRL) in Jackson, Michigan. Potential on-site sources for groundwater impact are two distinct landfill units at the MRL. Leachate chemistry suggested that landfill leachate was not the source of VOCs detected in groundwater. A potential source for VOCs was landfill gas. Sources of landfill gas in the vicinity of the impacted wells included the distinct MRL landfill units as well as the old Jackson County Landfill (JCL), located hydraulically downgradient from the impacted wells. …
