Factors That Relate To Job Retention For Former Welfare Recipients, Lisa Spadafore

Masters Theses

This descriptive study attempted to determine the factors that relate to job retention for former welfare recipients. Welfare recipients (15 women and 17 men), who were participating in a job club program, completed the Wonderlic Personnel Test (Wonderlic, 1985), the 16 Personality Factors Test (Eber, Cattell, & IPAT Staff, 1985), and a Background/Monetary Questionnaire. Thirty-two clients who obtained jobs were divided into two groups, those who retained their job for 90 days (n = 21) and those who did not (n = 11). Of the 31 factors analyzed, four showed a statistically significant relationship with job retention; amount of jail …

Effects Of Response Requirements And Reinforcement Probability On The Latency To Depress A Foot Treadle, Terri Deborah Starin

Masters Theses

Previous studies have shown response latency to be a sensitive measure of die effects of many experimental manipulations. However, when key pecking is the required response topography, it is difficult to ascertain whether latency is exclusively due to the effects of the independent variable or is confounded by respondent influences. The present study attempts to separate operant from respondent influences on response latency by requiring a response topography that is unlikely to have respondent components. Three pigeons responded under a multiple fixed-rado fixed-ratio schedule of food delivery with a 5 s intertrial interval separating trials. For two subjects, the independent …

Electrical Resistivity As An Approach To Evaluating Brine Contamination Of Groundwater In The Walker Oil Field, Ottawa County, Michigan, Janet A. Koehler

Masters Theses

Surface electrical resistivity successfully defined brine contamination within a glacial drift aquifer in western Michigan. The study site is in a residential area of eastern Ottawa County, in the Walker Oil Field. A Schlumberger array with a maximum current electrode separation (AB/2) of 316 meters (1037 feet) was used. It was possible to detect geoelectric layers to about 30 meters (100 feet) below ground level, with the maximum current penetration of about 1/10 (AB/2). On occasion, thick surficial clay precluded detecting deeper geoelectric layers. Through use of the INVERS computer program, fifty vertical electrical soundings were interpreted and correlated with …

The Use Of A Behavioral Checklist To Delimit And Define The Premenstrual Syndrome, R. Hope Kerr

Masters Theses

For the premenstrual syndrome (PMS), there is no consensus as to specific symptoms comprising the syndrome or their temporal relationship to the menstrual cycle. The purpose of this study was to delimit and define PMS by comparing contemporaneous, behavioral data collected by 3 groups of subjects.

Based on the results of this study, PMS is suspected of being a misnomer for frequently random symptoms which may or may not be menstrually-related. "Syndrome" is misleading since there is no group of symptoms specific to one group of women. "Pre-" and "menstrual" are also misleading because the symptoms do not occur consistently …

The Evaluation Of Efficiency Determination Of Screening Device (Pressure Screen) By Image Analysis, Rajeev Kumar Goyal

Masters Theses

The Omnicon 3600 image analyzer was used in the study of the evaluation of screening efficiency determination methods. It is very difficult to get a good over all contaminant mass balance across a pressure screen because of the factors involved such as sampling around a screen, time spent in collecting the samples, and possible size reduction of the contaminants by the pump and screen. The image analyzer gives the contaminant analysis in terms of the total number of particles, total area of all the particles, the mean particle area and a histogram of the contaminant size distribution. The histogram data …

Reconstruction Of A Real Object Using Stereo Vision, Ignatios E. Vakalis

Masters Theses

The problem of reconstructing a three dimensional object from its two dimensional image is the most critical problem which any powerful visual system must solve. The human visual system is known to solve this problem with impressive range and resolution. Computer solutions have fallen far short of human performance mainly because the solution process is poorly understood.

The reconstruction problem is solved using stereo vision. The distance of points on the object from the viewing device and the orientation of specific patches of the visual surface with respect to the viewing device are computed. Discontinuities in distance and orientation are …

Synthesis And Study Of Novel Quinoxaline Di-N-Oxide And 3-Acyl-2-Methylquinoxaline Di-N-Oxides, Cyprian Okwara Ogbu

Masters Theses

This research project consists of two parts. The first involved the synthesis of a novel quininoxaline di-N-oxide via benzofuroxan. The second part was the use of this compound as a synthetic precursor.

It was assumed that 3,4-dimethylaniline would be successfully converted to 5,6-dimethybenzofurazan 1-oxide (5,6-dimethybenzofuroxan) through a sequence of reaction steps. Fortunately, this assumption was correct as the desired compound was produced. This compound was utilized in synthesizing the novel 3-acetyl-2,6,7-trimethylquinoxaline 1,4-dioxide. From the structure of this adduct, it is believed that it will take part in condensation reactions associated with methyl ketones without disrupting the quinoxaline di-N-oxide framework, and …

A Study Of An Integral Equations For Computing Radial Distribution Functions, Noraini Ismail

Masters Theses

A two parameter integral equation, equation T is studied to compute radial distribution functions for a classical fluid whose single component particles interact pairwise according to a square-well potential function. A computer program originally written for a DEC 10 was modified to run on a DEC VAX. At the same time, modifications were made to take advantage of the faster VAX and to reduce the time an operator must spend to get a solution to the integral equation. Solutions were obtained for several densities, temperatures, and parameter values. Temperatures ranged from a high temperature gas to near critical temperatures. Accurate …

Characteristics Of Binding Of Interleukin-1 To Yt.Nci Cells, Susan Catherine Speziale

Masters Theses

Interleukin-1 (IL-1) demonstrated a concentration dependent, specific binding to the human, large granular lymphocyte cell line, YT.NCI with a dissociation constant of 0.2 nM. There were approximately 500 IL-1 receptors/cell.

IL-1 binding to YT.NCI cells could be inhibited by unlabeled-IL-1 and the plant lectins, WGA and Con A. Lectin inhibition of IL-1 binding could be completely abrogated by exposing lectins to specific simple sugars prior to the addition of ligand.

Tunicamycin, an inhibitor of glycosylation, decreased IL-l binding to YT cells in a reversible, time- and concentration-dependent manner.

These observations suggest that glycosylation of cell surface proteins may be important …

A Synthetic Approach To Novel Heterocyclic Herbicides, Paul Antony Pathadan

Masters Theses

The purpose of this research study was to prepare novel heterocyclic herbicides. The first phase of the project was to synthesize 1-(nitromethyl)-4-phthalazone.

In the second phase 1 - (nitromethyl)-4-phthalazone was treated with 1,3-propane-dithio-di-p-toluene sulfonate in presence of sodium hydride to get the target compound 4-(1'-nitro-l,3-dithiane)phthalazone.

It is believed that this compound might block the electron transport system of aerobic cells¹ . So further investigation of this compound may lead to novel herbicides.

The Significance Of Organic Complexing In The Mobility Of Iron In The Kl Landfill Leachate Plume, Kalamazoo, Michigan, James D. Rudder

Masters Theses

High iron concentrations in the leachate plume of the KL Landfill in Kalamazoo County, Michigan, persist in the presence of detectable hydrogen-sulfide. Under these conditions iron-sulfide minerals are highly oversaturated and should be precipitating. Calculations performed by the chemical equilibrium model WATEQF indicate over-saturation of selected iron-oxides, siderite, and iron-sulfides. Semilog plots of iron concentration versus time of exposure to air demonstrate retarded precipitation of ferric hydroxide, and analytical techniques of ion chromatography, Fourier transform IR spectrophotometry (FTIR), and UV-Visible spectrophotometry have yielded results which indicate that organic complexing of ferrous iron plays a significant role in the mobility of …

Composite Graph Coloring Algorithms And Applications, Stephen Hong Seng Yek

Masters Theses

"A vertex-composite graph is a graph that can have unequal chromaticities on its vertices. Vertex-composite graph coloring or composite graph coloring involves coloring each vertex of a composite graph with consecutive colors according to the vertex's chromaticity with no two vertices adjacent to one another having the same color(s).

New heuristic algorithms including the use of the saturation degree method have been developed in this research. All eleven heuristic algorithms including Clementson and Elphick algorithms were then tested using random composite graphs with five different chromaticity distributions. The best algorithm which uses the least average colors from the experiment is …
