Nitrate Levels In The Groundwater Of Kalamazoo County, Michigan, William Robert Norman

Masters Theses

Nitrate levels from 1,978 wells were compiled and analyzed to identify areas having levels above the Federal and State Drinking Water Standards of 10 ppm, identify possible sources of nitrate in each area and determine factors that produce high concentrations of nitrate in groundwater.

Eighteen areas in which nitrate concentrations exceeded 10 ppm were identified. County-wide, 465 (23 percent) of the wells for which data were available produced water with nitrate concentrations above drinking water standards.

Septic tank effluent is thought to be the most common source of nitrate in the problem areas. Agricultural practices are also likely nitrate contrbutors; …

Autocorrelation In Behavioral Time-Series Data: The Search Goes On, Robert James Anderson

Masters Theses

Many methodologists have asserted that serial dependency is a common data characteristic of research employing single subject responses measured over time. This dependency, when present, invalidates usage of most conventional data analysis techniques and may necessitate use of Auto-Regressive Integrated Moving Average (ARIMA) models which accommodate serial dependency characteristics of those data. Results indicate that minimal levels of serial dependency are present in most areas, yet is higher in areas which sample behaviors at very long or short time intervals and the dependent data usually show linear trend or cycle. A review shows that once trends and cycles are accounted …

A Comparison Of The Hutchings "Low-Stress”, Fulkerson Tens Method, And Conventional Addition Algorithms For Speed, Accuracy And Preference With Regular Education Students, Gregory N. Vaughan

The Effects Of Self-Recording On The Generality Of Parenting Behaviors, Sonia Beatriz Meyer

Masters Theses

The objective of this study was to determine the effects of parental self-recording from audiotapes of family interactions on effective parenting skills and on the generality of their application to three different times of the day in which different child behaviors occurred.

Two single parents were instructed to deliver correct commands and differential reinforcement and to code and graph their verbalizations from audiotapes. Self-recording was introduced in one situation at a time, while audiotaped assessments were made by the parent in all three situations throughout the day. Both positive and cost incentive systems were used for the delivery of tapes …

A Component Analysis Of Hutchings' Low-Stress Subtraction Algorithm With Third Grade Students, Karen J. Lascurettes

Masters Theses

This study measured the effects of what was hypothesized to be the major functional component difference between the Hutchings' low-stress subtraction algorithm and the traditional algorithm: the non-alternation of regrouping and subtraction steps. A multiple baseline design was used with two groups of third grade students. Dependent measures included rate correct, rate incorrect, percent accuracy, and types of errors made. Statistical analysis of the data failed to support the position that the non-alternation of regrouping and subtracting steps in subtraction yielded superior performances with these students. Future research in this area might investigate the inclusion of zeroes in the minuends …

Sampling The Invisible: Occupational Status In Victorian England, Rosamond Robbert

Masters Theses

Except for the highly unusual, women have been historically invisible. Based on the British Census of 1851, this exploratory and descriptive study uses a subsample of all heads of households drawn from a one-percent cluster sample of the population of Greater London. The theoretical model is stratification based on occupation, age, and sex. The occupational skill status of heads of households is examined and compared on the basis of age, sex, and marital status. Findings indicate that the major predictor of occupational skill is marital status, in complex interrelationships with age and sex. Women heads of households, supporting themselves in …

The Effects Of In-School And Out-Of-School Contracting On Academic Performance, Kelly Lynn Kent

Cleavage And Deoxygenation Of Phenolic Ethers, Derhsing Luu

Masters Theses

Dibromotriphenylphosphorane (DTP) in acetonitrile at 50°C was found to cleave ß-naphthylmethyl phenyl ether in preference to ß-naphthyl benzyl ether, 62% and 30% cleavage, respectively. Reaction of ß-naphthyl benzyl ether in dichloromethane at reflux produced 67% cleavage.

The quasiphosphonium complexes obtained by reaction of phenolic compounds with DTP were found to be reduced by several reducing reagents to give the corresponding aromatic hydrocarbons. Reaction of p-cresol with DTP, followed by lithium aluminum hydride reduction gave 38% toluene; sodium naphthalide reduction in THF gave 32% toluene; sodium in liquid ammonia reduction gave 12% toluene; sodium naphthalide reduction in DMF gave 15% toluene. …

A Laser Interferometric Study Of Electric Field Effects On Methane-Oxygen Flame Plasmas, Mark D. Prairie

Masters Theses

A laser interferometer is developed to study the refractive index field, aerodynamic structure, and three dimensional temperature profile of a methane-oxygen flame system under the influence of D.C. electric fields. A combined graphical-numerical method is used to transform the observed interference patterns into radial temperature distributions. The results indicate that the electric field exerts a marked influence on the flame stability, geometry, and charged particle flow. Experimental evidence shows that these effects are most apparent under fuel rich conditions. It is suggested an electric field may change the concentration gradients of reacting species, leading to an altered course of fuel …

The author addresses similiar difficulties encountered when restrictive sources of revenue are maintained as separate from the special education joint agreement budget.

This study was conducted for two purposes: (1) To develop a planning-budgeting system which would organize multi-sources of revenue into one joint agreement financial plan; and (2) To develop a planning-budgeting chart of accounts.

Five criteria were applied to the development of the planning-budgeting system: (1) It must allow for planning the total scope of joint agreement operations; …

A Community Climate Survey Of The Mattoon Community Unit #2 School District, Doug Craig

Masters Theses

School district boards of education and administrators need to constantly gather information about the attitudes and opinions of the community they serve if the true educational needs of the community are to be served. Total community consensus or opinion is preferable, but often impractical. Casual information gathered from self-selected individuals from the community is readily available, but unrepresentative and often misleading. Surveys of a selected sample of the school community can be inexpensive, practical and accurate depending on the method of information collection, the nature of the questions and the manner in which the sample is selected.

A Community Climate …

A Multivariate Analysis Of The Effects Of Money In Congressional Elections On Incumbents And Challengers, Larry Summary

Masters Theses

The use of money in congressional elections will be the principal issue of this thesis. The money decides who will mount a serious contest and who will not. In determining the effect of money in congressional races, it is hypothesized that campaign spending has a much greater effect on the challenger's chances of winning than it does on the incumbent's.

One of the many implications of this thesis is that people and groups determine how well a candidate will do on election day. Such topics as long term trends in the House, congressional competition, voting behavior, conservative and liberal political …

Proposal Of Development Of A Gifted Program To Be Implemented By South Eastern Special Education, Brenda Kaye Palmer Allen

Masters Theses

Since a major purpose of American education is to meet each child's individual needs, then the intellectually gifted children require the same consideration as those who are slow learners, handicapped, economically disadvantaged, or emotionally disturbed. Research reveals that there are approximately one and one-half to two million gifted children in the United States which means that between two and three percent of the students in any given classroom fall into this category. It is an alrming fact that between ten and twenty percent of the gifted students become high school dropouts and a much larger number never attend college. Presently, …

Controlling The Number Of Metal Sites To Which A Poly(Tertiary Phosphine) Coordinates To Group 6 Metal Carbonyls, Nestor Paul Hansen

Masters Theses

The compounds trisdiphenylphosphine(tricarbonyl) metal and trisdiphenylvinylphosphine(tricarbonyl) metal of molybdenum and tungsten were prepared. These compounds were allowed to react with diphenylvinylphosphine and diphenylphosphine, respectively, in the presence of azobis(2-methyipropio)nitrile or potassium t-butoxide to yield the complex containing bis(diphenylphosphino) ethane as a chelated ligand.

The tris-substituted compounds showed a large degree of lability which prevented the isolation of the desired, (OC)₃M(Ph₂PCH₂CH₂PPh₂)₃, compound which contains three ditertiary phosphines acting as monodentate ligands.

Coordinated diphenylphosphine and diphenylvinylphosphine pentacarbonyl compounds of chromium, molybdenum and tungsten were prepared and allowed to react in …

Monetary Factors And The Business Cycles, Nattasin Chongsanguan

Masters Theses

The emphasis in the study of economic fluctuations has been placed upon the disequilibrium nature of the growth process with private investment playing such a key role in generating oscillatory behavior. The view taken in this paper, however, is that fluctuations in aggregate economic activity are equilibrium phenomena. Expansionary and contractionary processes are considered as continuous adjustments along an equilibrium path through time.

The Hawtrey-Hicks monetary hypothesis is used in this study to explain irregular fluctuations in economic activity. Monetarist propositions together with rational expectations and dual-decision hypotheses are then drawn from the Hawtrey-Hicks analysis for the testing purposes. Quarterly …
