The Effect Of Neurosecretions From The Cerebral Ganglia On Blood Glucose Levels In Lumbricus Terrestris, Joan Vanderpol Craig
The Effect Of Neurosecretions From The Cerebral Ganglia On Blood Glucose Levels In Lumbricus Terrestris, Joan Vanderpol Craig
Masters Theses
Introduction
The presence of neurosecretory cells in the suprapharyngeal ganglia of Lumbricus terrestris has been well established (B. and E. Scharrer, 1937). Since these cells may well be the only source of hormones in this organism (B. Scharrer, 1959), the question arises as to their role in the animal's regulation of metabolism The particular aspect of this problem investigated here concerns the effect of these neurosecretory substances on the blood glucose levels in L. terrestris.
Preliminary studies by this investigator on glucose levels in earthworms revealed that blood samples of approximately 15 microliters could be obtained from each animal and …

Strain Differences In Alcohol Preference On Guinea Pigs And Experimental Manipulation Of Preference By Forced Alcohol Consumption, Gerald L. Appleman
Strain Differences In Alcohol Preference On Guinea Pigs And Experimental Manipulation Of Preference By Forced Alcohol Consumption, Gerald L. Appleman
Masters Theses
Introduction
The study of the determinants of alcoholism, one of the most perplexing diseases of mankind, entered its most fruitful era of discovery in the laboratory of the animal researcher. A pioneering study of the determinants of alcohol consumption by Richter (1940) indicated that laboratory rats show a preference for alcohol over water beginning at 1.8 per cent ethanol (v/v) solution, and continue to prefer alcohol over water up to a 6 per cent ethanol (v/v) solution. Richter made two important contributions to alcohol research which had broader implications than the presentation of an index of alcohol consumption in rats. …
Six Dimensions Of Religiosity And Riesman's Inner/Other-Direction, Edward E. Mckenna
Six Dimensions Of Religiosity And Riesman's Inner/Other-Direction, Edward E. Mckenna
Masters Theses
First three paragraphs:
To what extent do different types of religious behavior vary with different levels of inner- and other-direction?
Religious behavior is multi-dimensional in nature, with several qualitatively distinct dimensions. Hypothesized relations between different dimensions of religious behavior and inner/other-direction, together with the assumed shift from inner-direction to other-direction, have been formulated to explain the now familiar, but nevertheless controversial, religious revival in American society. This revival is controversial in the sense that it extends only to certain types, or dimensions, of religious behavior. There have been increases in church membership, identification, and ritual observance, but not in other …
Pain Elicited Aggression As A Function Of Withdrawal From Morphine Addiction, Brian G. Teel
Pain Elicited Aggression As A Function Of Withdrawal From Morphine Addiction, Brian G. Teel
Masters Theses
One branch of aggression research has concentrated on the elicitation of aggressive behavior by means of exteroceptive stimulation. Electric shock or similar painful stimuli (Ulrich & Azrin, 1962) are well known to produce fighting in the laboratory rat. This basic method has allowed experimental analysis of a wide scope of associated variables.
Ulrich and Azrin (1962) investigated several different parameters. They found that laboratory rats increased their fighting behavior as the frequency of shocks increased from 0.1 to 38 shocks per minute. With frequency fixed, the fighting response rate resembled an inverted U-shaped curve when shock intensity was increased from …

The Study Of The Metal Complexes Of Alpha Aminohydroxamic Acids, Richard N. Nipe
Masters Theses
Introduction
The objectives of this investigation were to develop: 1) compounds similar to hydroxy urea, a compound known to have anti-tumor activity, 2) a method to prepare α-aminohydroxamic acids and to study the complexes of these compounds with several metal ions, 3) computer programs to determine the pK's1 of the hydroxamic acids and the stepwise stability constants2 for the ligands and several metal ions.
The values obtained for the stability constants were compared with values for the stability constants of acetohydroxamic acid and α-aminocarboxylic acids in an attempt to find which in the ligand formed bonds with the …
Budget Effects On Defense Planning, Charles Ventura
Budget Effects On Defense Planning, Charles Ventura
Masters Theses
Preface
The Department of Defense (DOD) program budget was developed to link defense planning to defense spending. The budget is designed to reflect total program costs. Military managers require such costs in order to make optimum allocation of resources. The program budget has been a useful tool in bringing uniformity to military plans but its effectiveness, the author contends, has been limited because it contains inaccurate cost data.
The author intends to prove that incorrect financial information is included in the budget because some resource expenditures cannot be accurately traced. The same resource is "common" to several different weapon systems. …

Game Theory And Power Politics, Michael Decker
Game Theory And Power Politics, Michael Decker
Masters Theses
Preface
The contemporary argument over method reaches into all the traditional diversions of social science, of which political science is no exception. Such names as structure-functionalism, decision theory, systems analysis, behavioralism, and game theory have become commonplace identifications of political methodologies in the twentieth century. And if one consideration has generated this plethora of seemingly novel approaches to the study of politics, it is an epistemological one. Indeed, the argument seems to center around determining that kind of intellectual behavior which will best enable the student to understand political events.

It is proposed in what follows that, in the …
Studies On The Preparation Of Tetrasubstituted Hydrazones, William Kao
Studies On The Preparation Of Tetrasubstituted Hydrazones, William Kao
Masters Theses
Introduction
In a recent study of the ultraviolet spectra of substituted hydrazones, it was concluded that a sterio effect existed in tetrasubstituted hydrazones that significantly hindered complete rotation about the nitrogen-nitrogen bond. Weber16 noted that di- and tri-substituted hydrazones exhibited similar spectra with three strong absorption bands at approximately 235, 300, and 340 mu. In acid solutions, the spectra of these compounds showed a marked decrease in intensity of the long wavelength band. It has been postulated that this change was a consequence of the protonation of the non-bonding electron-pair on the amino nitrogen atom, and thus correlated the …
An Examination Of The Attitudes Of Students In Clinical Training Toward Concepts Judged Important To The Therapeutic Process, David B. Ingram
An Examination Of The Attitudes Of Students In Clinical Training Toward Concepts Judged Important To The Therapeutic Process, David B. Ingram
Masters Theses
The Background and Purpose of the Study
Introduction
This study is generally concerned with an evaluation of the proficiencies of speech therapists in training. The importance of this area, while obvious, has received little formal recognition in the field of speech pathology. That this topic has not been the concern of more research may be understood when we consider a contemporary and authoritative definition of the word 'therapy'. Colby (5, p. 95) states that therapy is: "...a practical art, a craft like agriculture, or medicine or wine making in which an artisan relies on an incomplete, fragmentary of knowledge and …

Masters Theses
The Challenge of the 60's
The city of the 1960's us awakening to its present condition and is attempting to take positive steps towards the alleviation or the solution of a multitude of problems. Typical of the problems is the erosion of the local tax base, a loss of population, an increase in crime and delinquency, and persistent demands by fringe area residents for extensions of municipal services. A problem that affects cities of all sizes is that of blight, deterioration, and decay. One method of dealing with this problem is through local participation in the Federally-sponsored urban renewal program. …

Identification Of Long-Tenure Hourly Factory Workers Using A Weighted Application Blank, Joffrey Michael Dornon
Identification Of Long-Tenure Hourly Factory Workers Using A Weighted Application Blank, Joffrey Michael Dornon
Masters Theses
A cursory examination of employment application blanks, so commonly used in modern business, reveals that two kinds of data are normally requested of a job applicant. The first kind of data are items necessary for the identification of the prospective employee: name, age, sex, address, and so on to the extent permissible and required by existing law and customary personnel administration procedures.
The use of the second kind of data contained in application blanks is seldom explicitly stated but is assumed to be of greater importance for personnel selection decisions. Information regarding previous job history, hobbies, and related activities and …

The Application Of The Verwey-Overbeek Theory To The Relative Sediment Volume Of Kaolin-Water Dispersions, James E. Kline
The Application Of The Verwey-Overbeek Theory To The Relative Sediment Volume Of Kaolin-Water Dispersions, James E. Kline
Masters Theses
Introduction
This paper describes an investigation intended to: 1. observe the effect of electrolyte concentration on the stability of kaolin-water systems, 2. evaluate the relative sediment volume measurement as a tool for determining the stability of such systems, 3. assess the applicability of the Verwey-Overbeek theory of stability of lyophobic colloids for predicting the observed effects, and 4. determine if any correlation exists between the effects predicted by the theory and observed through the relative sediment volume measurement.
The relative sediment volume measurement will be shown to be dependent upon the efficiency of packing of the pigment particles, which in …

Foreign University Students’ Image Of The United States Of America, Austra P. Balks
Masters Theses
Observations
As a foreign-born student this writer has been exposed to differing views about the United States of America, particularly with respect to its ideological background and some facets to its culture. Many of these views have not corresponded with facts observed about life in the United States, as revealed to the writer after she had resided in this country for a time. Among fellow immigrants, this writer stated that the longer one lived in the United States one's attitude became more understanding and positive toward the United States.
The writer had observed earlier that in many respects the basic …
Dimethyl Sulfoxide Oxidation Of Primary Alcohols, Carmen Vargas Zenarosa
Dimethyl Sulfoxide Oxidation Of Primary Alcohols, Carmen Vargas Zenarosa
Masters Theses
Historical
A method of selective oxidation of primary and secondary alcohols to the corresponding aldehydes and ketones has been developed recently, namely the use of dimethyl sulfoxide (DMSO) as the oxidizing agent, either alone or with dicyclohexylcarbodiimide (DCC)14, acid anhydrides1, or alkyl chloroformates10. The negatively polarized oxygen atom of the sulfoxide group in DMSO is ideally situated for a transfer to many electron-deficient substrates. The oxygen of the alcohol coordinates with the sulfur atom of DMSO through its oxygen atom; this is followed by β-elemination of dimethyl sulfide, thereby resulting in oxidation of the …

An Investigation Of The Use Of The Semantic Differential For Assessing Reactions To Stuttering Behavior, Douglas J. Spurlock
Masters Theses
Introduction
The professional literature in the field of speech pathology contains a great many references to stuttering. A large part of this literature on stuttering has dealt with the problem of severity. The importance of the concept severity of stuttering can be viewed in its relation to the broad theoretical constructs in the field of stuttering. Severity is a way of quantifying the extent of abnormality or degree of interference with the normal speech process. To say that one stutter is more severe than another is to say that he appears to be more abnormal than the other. Severity of …

Sir Frederick Lugard, World War I And The Amalgamation Of Nigeria 1914-1919, John F. Riddick
Masters Theses
Introduction
Throughout the First World War, world attention focused mainly on Europe's Western Front. There, the human carnage, the destruction, and the ruin created grave pressures which spread throughout the world. Though remote and detached, the continent of Africa encountered these powerful forces. In Nigeria, the focal point of this study, the conflagration impeded the colony's administrative development while it spurred its economic growth. Nor did it escape the blood bath, for Nigerian forces fought in both East and West Africa. Before the outbreak of the war, the British government had made the decision to give Nigeria a centralized colonial …

An Investigation Of The Surface Temperature Distribution In The Detroit Region, Allen R. Smith
An Investigation Of The Surface Temperature Distribution In The Detroit Region, Allen R. Smith
Masters Theses
Chapter I
Introduction
Climate and the City
Studies made of temperature in and around cities have shown the climate of the city to be anomalous in relation to its regional climate. The extent of this anomalous condition and the reasons for its occurrence vary from city to city and from season to season. So many variable factors are present in the generation or regeneration of heat within the city that no study has yet satisfactorily explained the total factors involved, or has indicated the percentage for which any one factor might be responsible. This being the case, the only objective …
The Effects Of Estrogenic And Gonadotrophic Hormones On Normal Levels Of Some Blood Chemical Constituents In The Non-Breeding Female Mallard Duck, Wendell F. Hofman
The Effects Of Estrogenic And Gonadotrophic Hormones On Normal Levels Of Some Blood Chemical Constituents In The Non-Breeding Female Mallard Duck, Wendell F. Hofman
Masters Theses
Introduction
In past years, a substantial amount of research has centered on the levels of certain blood chemical constituents in birds, particularly in chickens and pigeons. However, little has been recorded concerning the blood chemical constituents of the mallard duck, Anas platyrhynshos. Likewise, the effects of hormones on its blood chemistry, in conjunction with its reproductive system, have been almost totally unexplored. Therefore, this study, conducted from October 14, 1965, to March 3, 1966, had as its purpose the determination of normal quantitative levels of certain blood chemical constituents (the electrolytes--calcium, sodium, potassium; the proteins--albumin and globulin; and lipids) and …
