A Study Of Selected Photo Fries Rearrangements, Elwood Lloyd Loveridge

Theses and Dissertations

The Fries rearrangement of phenyl esters is reviewed and compared to the reaction when light is the source of energy. The products are different due to different mechanism of reaction. Light energy causes either free radical or concerted reactions. The S-phenylthiol esters and anilides were studied also. Although many of the rearrangements are the same, we did not see any alkyl migration nor decarboxylation type reactions with either the sulfur or nitrogen compounds. Three papers have been published from this work: Bradshaw, J. S., Knudsen, R. D. and Loveridge, E. L., J. Org. Chem., 35, 1219 (1970); Bradshaw, J. S., …

Voltammetric And Electrochemical Kinetic Studies Of The Halides And Halogens At A Platinum Rotating Ring-Disk Electrode In Anhydrous Acetic Acid, Donald Harrison Cranney

Theses and Dissertations

The electrochemical behavior of the iodine-iodide couple was investigated in both basic and neutral acetic acid solutions at a platinum rotating ring-disk electrode. Voltammetric curves were obtained and discussed. Various kinetic parameters were determined and by comparing to theoretical kinetic parameters a probable reaction mechanism was deduced. The mechanism that best fit experimental results is the following I- + S = I(S) + e- I(S) + I- = I2 + S + e (slow). The electrochemical behavior of bromine, bromide, and chloride was also investigated in the same media. Voltammetric curves were recorded and discussed with emphasis on the hysteresis …

The Supreme Court, Philosophy And Freedom Of Choice: An Analysis, Walter N. Blevins

Theses and Dissertations

It is a major contention of this thesis that to argue, debate and philosophize about choice and freedom of choice is one thing, but arguments as to the existence of free choice and claims to its exercise do not mean much, unless within the framework of social and political life the freedom is recognized and protected by some legal authority— in this case, the United States Supreme Court.

This thesis is directed at two areas of political research. First will be a survey and examination of current philosophic literature in order to specify and describe the various models employed in …

Processing Pictorial Information: Effects Of Informativeness, Location, And Duration, Richard L. Metzger

Theses and Dissertations

When an observer views a picture, enough information processing occurs prior to the first eye movement to direct the eyes to an informative portion of the picture. This early processing is influenced by the overall coherency of the picture and the informativeness of the various sections of the picture. The present study tested the hypothesis that the processing of pictorial information proceeds in a hierarchical manner from the most informative sections of a picture to the least informative sections. The hypothesis was evaluated by observing changes in the recognition accuracy of high medium and low informative sections of a picture, …

The Attribution Of Fault To Rape Victims: Subject Variables Affecting Blaming, Stephan Podrygula

Theses and Dissertations

This study investigates the subject variables involved in the attribution of fault to rape victims. A consideration of attribution theory, in particular Heider's "naive analysis of action," suggests that innocent victims of misfortune will be blamed, however implausible this at first seems. Heider's theory has led to two specific theoretical explanations for blaming, E. Walster's defensiveness hypothesis and Lerner's just world hypothesis, both of which are examined in some detail. The relevant theoretical and experimental literature is reviewed, an assessment of the current standing of these explanations is made, and unresolved issues are raised. Several issues and questions based on …

Defense Mechanism And Feeding Behavior Of Pteraster Tesselatus Ives (Echinodermata, Asteroidea), James Milton Nance

Theses and Dissertations

Pteraster tesselatus is noted for its external secretion of massive amounts of mucus. The mucus repels most animals, and fouls their respiratory physiology, if contact is maintained for any length of time. It provides protection essentially 100% of the time from Solaster dawsoni and Pycnopodia helianthoides, the only local stars that attempt to feed on Pteraster. The mucus, which is a simple mucopolysaccride, is produced in three different types of unicellular glands located in the epidermal tissues along the supradorsal membrane. Pores along the lateral walls of the ambulacral grooves provide fresh sea water for the dermal branchiae contained in …

The Intermolecular Potential And Vibrational Relaxation Of The Ar-Co System, Gregory Allen Parker

Theses and Dissertations

The angle, distance and vibration dependence of the Ar-CO intermolecular potential is calculated using the electron gas model to obtain the short range interaction which is smoothly joined onto the long range van der Waals tail which is obtained from accurate C_6, C_7, and C_8 coefficients. Our calculated second interaction virial coefficients are compared with experiment and with a simple adjustment of the Ar-CO potential an excellent agreement is obtained. Our spherically averaged potential is also in excellent agreement with a spherical potential inferred from high energy scattering data. Simplified expressions for the scattering amplitude and differential cross section are …

The detectable range for each method is given. The NMR method is a fast and convenient method for the magnetic susceptibility determination of a sample in solution, with. accuracy up to ± 1%.

Some Effects Of Model Status On The Reduction Of Anxiety, Barbara Jane Benner

Theses and Dissertations

Bandura and his colleagues have demonstrated that modeling techniques using fearless "mastery" models can be useful in helping clients overcome irrational fears (Bandura, Grusec and Menlove, 1967; Bandura and Menlove, 1968; Bandura, Blanchard and Ritter, 1969). Later, Meichenbaum (1971) found that initially fearful "coping" models who gradually overcome their fear are more effective than mastery models. However, research on the effects of model status has not investigated coping models. The present study attempted to discern how model status influences the effectiveness of coping models.

Thirty-two female Introduction to psychology students who reported themselves to be speech anxious were asked to …

An Investigation Of Modal Auxiliary Verb Acquisition By Children Three To Seven Years Of Age, Cheryl Rae Mayer

Theses and Dissertations

The present study was designed to investigate the performance of twenty-one modal and quasi modal auxiliary verbs by normally-developing children aged 3-0 to 6-11 years on two experimental tasks involving each an imitated and elicited language task.

A one-hundred utterance elicited language task in response to toy and picture stimuli and a seventy-eight sentence imitation task were administered to fifteen subjects at each of the four age levels: 3-0 to 3-11 years, 4-0 to 4-11 years, 5-0 to 5-11 years, and 6-0 to 6-11 years.

Statistical analysis of the performance of the four subject groups revealed significant differences among subject …

Development And Implementation Of An Inquiry-Oriented Mapping Curriculum In The Intermediate Grades, William Whitney Janeway

Theses and Dissertations

The main purpose of this study was to produce an inquiry-oriented curriculum in map making and map interpretation for the intermediate grades. The curriculum was fully developed on the basis of field testing during a pilot study.

To accomplish this goal, eight classrooms were selected to participate in an inquiry-oriented course in mapping. This pilot study involved nearly 200 students in two one-hour sessions per week for eight weeks. The experimenter conducted all of the teaching activities and kept a detailed journal of observations, updated immediately after each session. Evaluation and modification of activities took place throughout the study. This …

Effects Of Psychodrama On Self-Actualization And Perceived Locus Of Control, Stanley W. Rosenthal

Theses and Dissertations

Despite psychodrama’s popularity as a clinical procedure, few adequately controlled outcome studies have been reported. The purpose of this study was to determine whether participants in short-term psycho drama groups, relative to controls would show greater change in selfactualization, locus-of-control, and positive "back-home" behavior reported by significant others. Since protagonists emerged spontaneously from their groups, it was also possible to: (a) determine whether protagonists gained more from the psychodrama experience than less active group members, and (b) identify personality and demographic characteristics associated with participants’ willingness to assume the protagonist role.

Forty-four volunteers from a university community were randomly assigned …

Effect Of Hemorrhage On Blood Flow To Marrow And Osseous Tissue In Conscious Rabbits, Glenn T. Syftestad

Theses and Dissertations

The purpose of this experiment was to characterize cardiovascular responses in skeletal tissue 15 minutes and 16 hours following reversible hemorrhagic hypotension and to validate a quantitative method for measuring blood flow rates in marrow and bone.

Cardiac output and regional blood flow determinations were made using the radioactive microsphere technique. Microspheres (15 u dia) were injected into unanesthetized rabbits via a chronically implanted left atrial catheter. Blood flow and cardiac output measurements were made by injecting individual microsphere isotopes, each with a different label (®^Sr, 5 1 c r Gr l ^ C e ) , at three specified …

Solid-Liquid Phase Equilibria In Systems Of (I) Para-Xylene, (Ii) Mesitylene, And (Iii) N,N-Dimethylformamide ; Excess Volume Determination In Systems Containing Cyclohexane ; Calculations Of Activities For The N-Hexane + Cyclohexane System, John F. Moellmer

Theses and Dissertations

Solid-liquid phase equilibria studies were used to investigate possible compolllld formation in solutions of (i) para-xylene, (ii) mesitylene, and (iii) N,N-dimethyl-formamide (DMF) with mono- and di- halobenzenes that were selected to give a wide range of acceptor properties. Solid 1:1 intermolecular compounds were identified from solutions of p-C_6H_4F_2 with mesitylene, p-C_6H_4Br_2 with p-xylene, and p-C_6H_4Cl_2 with p-xylene. The results suggest that compound formation occurs because of favorable geometry rather than a charge transfer process. A vibrating tube densimeter was used to determine, with high precision, the densities and subsequently excess volumes of mixing of the n-hexane plus cyclohexane system. Temperature …

The Measurement And Reporting Of Human Resources - Its Feasibility And Utility, Wesley J. Simonson

Theses and Dissertations

Financial accounting is dynamic. It's generally accepted accounting principles are the result of an evolutionary process that can be expected to continue. Accounting is not an art which is an end in itself, rather it is an activity with a purpose. It is an information system whose principles change in response to changes in economic and social conditions, to new knowledge, and to demands of users for more serviceable financial information. Human Resource Accounting (H.R.A.) is a part of this evolutionary process. It is a response to a need for information in an area previously considered to be outside the …
