A Review Of "Longitudinal Study" In Developmental Psychology, Emily H. Finley
A Review Of "Longitudinal Study" In Developmental Psychology, Emily H. Finley
Dissertations and Theses
The purpose of this library research thesis is to review the "longitudinal study" in terms of problems and present use. A preliminary search of the literature on longitudinal method revealed problems centering around two areas: (1) definition of "longitudinal study" and (2) practical problems of method itself. The purpose of this thesis then is to explore through a search of books and journals the following questions:
1. How can “longitudinal study” be defined?
2. What problems are inherent in the study of the same individuals over time and how can these problems be solved?
A third question which emerges from …
Reaction Of Aqueous Catechol Solutions With Minerals, Boonthong Poocharoen
Reaction Of Aqueous Catechol Solutions With Minerals, Boonthong Poocharoen
Dissertations and Theses
The effectiveness of catechol, an aromatic vic-diol, in dissolving silicate minerals was studied. A synthetic amorphous magnesium trisilicate, Mg₂Si₃O₈∙5H₂O, as well as the minerals olivine, sepiolite, diopside, augite, and enstatite were used to react with catechol in slightly acidic, basic, and neutral solutions. It was found, depending on the solvent used, that 33-52, 8-17, 14-30, 5-11, 3-6, and 0.5-1 % of the minerals dissolved, respectively.
The reaction with Mg₂Si₃0₈·5H₂0 resulted in the formation of crystals of magnesium tris (catecholato) siliconate nonahydrate Mg[Si(Cat)₃]∙9H₂0. Dehydration of the crystals at room temperature resulted in the loss of 6 moles of water to form …
On The Mechanism Of The Diels-Alder Reaction--Dimerization Of Trans-Phenylbutadiene, Michael Ward Mcnicholas
On The Mechanism Of The Diels-Alder Reaction--Dimerization Of Trans-Phenylbutadiene, Michael Ward Mcnicholas
Dissertations and Theses
The Diels-Alder dimerization of trans-1-substituted butadienes is expected to yield a cyclohexene adduct with the substituents in the 3 and 4 positions cis to one another. This prediction is based on past observations of other Diels-Alder additions. The cis-isomer is the only one consistent with a two-stage mechanism proposed by Woodward and Katz.
In the case of trans-phenylbutadiene, the expected adduct is cis-3-phenyl 1-4-(trans-styry1) cyclohexene. Alder, Haydn and Vogt, however, reported that the corresponding trans-isomer is the dimerization product. There is reason to believe that the observation of the trans-isomer may have been the result of product isomerization during purification. …

Adsorption Of Sulfur Dioxide On Douglas Fir Woodchips, Uen-Ping David Wang
Adsorption Of Sulfur Dioxide On Douglas Fir Woodchips, Uen-Ping David Wang
Dissertations and Theses
In recent years, people have raised their alertness to the hazard of air pollution. Sulfur dioxide is one of the most dangerous chemical compounds among those air pollutants. A study on removing sulfur dioxide from an air stream by adsorption using wood chips as the adsorbent is presented in this thesis.
The reason for using wood as an adsorbent is that wood is a porous material and possesses a large surface of cell cavities which can hold a great amount of moisture. As sulfur dioxide gas is passed through the wood bed, it would be either condensed in the cell …
A Regional Approach: City-County Consolidation As A Method Of Local Governmental Reorganization, Anthony Gene White
A Regional Approach: City-County Consolidation As A Method Of Local Governmental Reorganization, Anthony Gene White
Dissertations and Theses
City-county consolidated governments are examined to isolate factors important to the success of the consolidation process, and are measured against objective and subjective criteria for the operation of such governments. Data are obtained through survey techniques and statistical analysis of demographic information. Results indicate that such success-oriented consolidation factors inherent in city-county governments do exist and can be interrelated in a mathematical model. Consolidated governments appear to improve their ability to handle urban problems, and officials of consolidated governments are more confident of their ability to handle these problems than are officials of other metropolitan governments reorganized in different manners.

Comment On Electron Scattering In The Image Potential Well, Pavel Smejtek, M. Silver
Comment On Electron Scattering In The Image Potential Well, Pavel Smejtek, M. Silver
Physics Faculty Publications and Presentations
Comments are made on the model of electron injection into SiO₂ proposed by Berglund and Powell. Their assumptions on electron scattering, disregarding the change of the escape cone with the distance from the emitter, lead to serious underestimation of the injected current. Two alternative models of electron injection, based solely on elastic scattering are discussed and do not predict the experimental results. We suggest that observed field dependence of the injected current into SiO₂ indicates that energy relaxation associated with the injected electrons is responsible for the voltage dependence of the current.
Geophysical And Geological Analysis Of A Fault-Like Linearity In The Lower Clackamas River Area, Clackamas County, Oregon, Ronald Jay Schmela
Geophysical And Geological Analysis Of A Fault-Like Linearity In The Lower Clackamas River Area, Clackamas County, Oregon, Ronald Jay Schmela
Dissertations and Theses
A fault-like linearity along the lower Clackamas River is evaluated by analysis of physiographic and structural alignments, geological relationships, and by gravity and magnetic data. The study has resulted in the verification of a structural feature extending along the Clackamas River and the eastern front of the Portland Hills.
Physiographic alignments were examined in twelve 15 minute and two 7-1/2 minute quadrangle maps. A significant northeasterly morphologic trend, N. 20⁰ W. and N. 40° W., and other secondary trends, namely, the N-S, E-W, and N. 50-60° E., has developed in the Portland area. The consistent northwest trend is observed throughout …
Evidence For The Existence Of Two Stable Sites For Cobalt Impurity Atoms In Aluminum, Arun Venkatachar
Evidence For The Existence Of Two Stable Sites For Cobalt Impurity Atoms In Aluminum, Arun Venkatachar
Dissertations and Theses
Using Fe57Mössbauer spectroscopy, two alternative sites occupied by cobalt (10-4 at. % ) impurity atoms in aluminum have been isolated. The substitutional site A is the stable position after annealing the sample above 840 K, followed by a rapid quench. The impurity atoms in site A are characterized by a single line Mössbauer spectrum (indicative of a cubic environment), a room-temperature f = 0.502 (r. m. s. displ. 0.071 A) and an I. S. (reI. to Fe) = -0.421 mm/sec. For anneals below 770 K the cobalt atoms migrate to site B, which is characterized by a …
On The Molecular Theory Of Dielectric Polarization In Rigid‐Dipole Fluids, John D. Ramshaw
On The Molecular Theory Of Dielectric Polarization In Rigid‐Dipole Fluids, John D. Ramshaw
Physics Faculty Publications and Presentations
A molecular theory is developed for the polarization P(r) produced by a weak position‐dependent external electric field E0(r) in a finite fluid system, of arbitrary shape, composed of rigid polar molecules. The theory differs from earlier work in that no assumption is made concerning the form of the electrostatic constitutive relation. [The usual assumption in this regard is that P(r) = (ε–1) E(r) / 4π, where E(r) is the total Maxwell electric field. The “dielectric constant” ε is well defined only if the relation between P(r) and E(r) …
Crystal Structure Determination Of Β-Lactoglobulin From Electron Micrographs, Richard Roeter
Crystal Structure Determination Of Β-Lactoglobulin From Electron Micrographs, Richard Roeter
Dissertations and Theses
Often electron micrographs exhibit a repeating structure. Sometimes this repeating structure satisfies the definition of a crystal in that it has a three dimensional repeating structure. If the unit cell structure of this repeating structure can be determined it can be used to help categorize different sections of a particular sample. In some cases, the use of optical diffraction analysis of electron micrographs with repeating structure is a method of determining the unit cell structure.
Samples of β-Lactoglobulin were prepared for viewing in the electron microscope using both the crystalline material and carbon replicas of the crystal surface. Because the …
Behavioral Changes Due To Overpopulation In Mice, James Robert Hammock
Behavioral Changes Due To Overpopulation In Mice, James Robert Hammock
Dissertations and Theses
Previous research has found that if a population were allowed to exceed a comfortable density level, then many catastrophic events occurred such as increased mortality among the young, cannibalism, homosexuality, and lack of maternal functions. The most influential researcher in this area is Calhoun (1962), after whose experimental design a pilot study was fashioned to replicate his results. The results of this pilot study inspired a more detailed research project of which this thesis is an account.
Forty-eight albino mice of the Swiss Webster strain were divided into three groups of sixteen each. Each group consisted of ten females and …
Implications Of An Oral-Gestural Training Program In The Acquisition Of Speechreading Skills, Mary Lu Wood
Implications Of An Oral-Gestural Training Program In The Acquisition Of Speechreading Skills, Mary Lu Wood
Dissertations and Theses
In order for the hearing handicapped child to derive maximum benefit of language acquisition through maturation, a method of receptive communication is essential at the earliest age possible. It is felt that speechreading is this method. The need for a method of training speechreading cues to prelingual, aurally handicapped children is based on the fact that most visual speechreading methods require the use of language. If speechreading can be regarded as a learning process involving the discrimination of visual cues that maybe disassociated from language expression then training the child to discriminate various facial expressions may actually enhance speech-reading ability. …
Rilke Und ValéRy: Eine Wahlverwandtschaft, Anne Marie Roehr
Rilke Und ValéRy: Eine Wahlverwandtschaft, Anne Marie Roehr
Dissertations and Theses
The German poet Rainer Maria Rilke was proficient in languages, and his favorite one was French. He had lived in Paris and had many friends in French literary circles. He exchanged letters with some of them before he even met them personally; such was the case with the French poet and writer Paul Valéry. However, before the two poets met, a “meeting of the minds” had taken place in the year 1921.
In the spring of 1921, after a lengthy period of silence, Rilke came across a copy of the Nouvelle Revue Française, a famous literary review, where Valèry had …

Dielectric Polarization And Alignment And The Structure Of Polar Fluids, John D. Ramshaw, D. W. Schaefer, John S. Waugh, J. M. Deutsch
Dielectric Polarization And Alignment And The Structure Of Polar Fluids, John D. Ramshaw, D. W. Schaefer, John S. Waugh, J. M. Deutsch
Physics Faculty Publications and Presentations
An analysis is made of the information about the structure of dense polar fluids which resides in the dielectric constant, the Kerr constant, and the nuclear magnetic resonance (NMR) quadratic electric field effect. The inadequacy of the "local-field" model for liquids is discussed. The existence of a nonzero molecular hyperpolarizability is shown to destroy an equivalence which would otherwise exist between the Kerr and NMR experiments, and can easily account for apparent discrepancies between the reported Kerr and NMR data for nitrobenzene and nitromethane. A method is presented for removing dielectric boundary effects from statistical averages, so that the averages …
Teaching Social Studies From A Global Viewpoint, Janet Hays Clemmer
Teaching Social Studies From A Global Viewpoint, Janet Hays Clemmer
Dissertations and Theses
The need for preparing our youth to live in an interdependent world on this finite planet has become urgent since the beginning of the nuclear age at the end of World War II. There is a need to extend the loyalty of the citizen tor the nation-state to human needs seen from a global view. The involvement of the United States in the international community already is extensive because of its predominant power. This involvement is not reflected in our education, either from the amount of time devoted to social studies in our schools or in the emphasis on international …
MöSsbauer Studies Of Stable Interstitial And Substitutional Sites Of Cobalt In Gold, Charles Freeland Steen
MöSsbauer Studies Of Stable Interstitial And Substitutional Sites Of Cobalt In Gold, Charles Freeland Steen
Dissertations and Theses
Precision measurements of the Debye-Waller factor of Fe57 in Au using the wide black absorber technique have been made in the temperature range from room temperature to 830 K. The major source of error arises from Au Ly x-rays which are unresolved by the radiation detection system from the 14.4 KeV gamma ray. The K absorption edge of Br has been used to correct for the presence of x-rays.
These measurements have revealed the existence of two nonequivalent lattice sites which the Co57 impurity (parent of Fe57) may occupy. One of the sites has been …

Electron Optical Study Of A Secondary Electron Multiplier, Chang Min Shen
Electron Optical Study Of A Secondary Electron Multiplier, Chang Min Shen
Dissertations and Theses
Electron orbital theory was applied to the design of the geometrical structure of an electron multiplier for an image intensifier. A special structure satisfying production requirements was studied. Electron optical calculations consisted of determining the potential distribution and tracing the electron trajectories. Liebmann's procedure was used to solve Laplace's equation with constant potentials on the multiplier electrodes as boundary conditions. The trajectories were determined by solving the equation of motion in an electrostatic field using a Runge-Kutta procedure. The initial conditions for the trajectories were the initial energies, initial positions, and the initial directions of the secondary electrons. The plotted …
