Comparison Of Acquisition And Generalization Levels Of Manual Signing With Moderately Retarded Persons (Language, Parent Training)., Cynthia Sue Allen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Educators working with mentally retarded and other severely communication-delayed students have begun incorporating sign language into their curriculum to promote language development. In most instances, these methods do not facilitate generalization to the natural environment where the language is actually used. This study investigated whether acquisition of sign language with moderately mentally retarded individuals is attained faster when taught in home settings by the parent or at school by the teacher in a clinical environment. Six students, ages six to twenty, attending a public special education program in central West Virginia served as subjects. All were diagnosed as moderately mentally …

The 1954 Geneva Conference: Eisenhower's Indochina Policy., Francis Noland Dawson Jan 1985

The 1954 Geneva Conference: Eisenhower's Indochina Policy., Francis Noland Dawson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Indochina phase of the Geneva Conference of 1954 played a critical role in the ending of the First Indochina War and prepared the way for the involvement of the United States in the Vietnam conflict. Little is understood of the conference because of a paucity of information available. Recently, this deficiency has been corrected somewhat as various departments and agencies have begun to declassify documents. An analysis of these new materials reveals that the United States did not have a well-defined policy in mid-1954 and that Eisenhower responded in an ad hoc fashion to conditions on the battlefield in …

Dissolution Kinetics Of Hydrocortisone Into Polymer Solutions (Steroids)., Nahla Nassar Khoury

Graduate Theses, Dissertations, and Problem Reports (ETD)

A major concern of investigators during the last decade has been the evaluation of the relative therapeutic effectiveness of competitive drug products. The problem of bioavailability is further exaggerated for steroidal drugs formulated as suspensions because of low intrinsic solubility, and the addition of stabilizing ingredients, such as polymers, to the formulations. An in vitro evaluation of the dissolution rate of hydrocortisone alcohol and acetate from constant surface area tablets into dilute polymer solutions was undertaken since dissolution rate is a relevant characteristic concerning therapeutic availability for sparingly soluble drugs. Polymers of varying chemical type and in dilute concentrations, similar …

The Influence Of A Thermal Oxide Layer On Short-Term Degradation Of Silicon Mis Solar Cell Output., Abdul Rahman Alamoud Jan 1984

The Influence Of A Thermal Oxide Layer On Short-Term Degradation Of Silicon Mis Solar Cell Output., Abdul Rahman Alamoud

Graduate Theses, Dissertations, and Problem Reports (ETD)

Metal-semiconductor (Schottky-barrier) solar cells have lower open-circuit voltage than p-n junction solar cells. The open-circuit voltage of a Schottky-barrier solar cell can be increased by the use of an ultrathin oxide layer between the metal and the semiconductor. Fabrication and testing of MIS solar cells with steam-grown oxide layers shows that short-term degradation occurs (within six weeks) and is indicated by lowering maximum power output. Degradation occurs independent of environmental conditions. Auger Electron Spectroscopy (AES) depth-profiles show that degradation is due to growth of a metal-oxide layer at the metal-SiO(,2) interface. This process occurs in a few weeks; with high …

Arene Pyrolysis. Relative Stabilities Of Benzylic Radicals., David Allan Robaugh

Graduate Theses, Dissertations, and Problem Reports (ETD)

The thermal unimolecular decomposition of ethylbenzene, iso-propylbenzene, t-butylbenzene, n-propylbenzene, isobutylbenzene, neopentylbenzene, 4-ethylstyrene, 1-phenyl-1-butene, 1-1 diphenyl-ethane, and 2-2 diphenylpropane was studied using the very-low-pressure pyrolysis (VLPP) technique. Each reactant decomposed by way of c-c bond fission producing an alkyl radical plus a benzyl or benzylic-type radical. RRKM calculations show that the observed rate constants when combined with thermochemical estimates are consistent with the following high-pressure rate expressions: log(k/s('-1)) = 15.3 - (72.7/(theta)) for ethylbenzene (1053 - 1234K), log(k/s('-1)) = 15.8 - (71.3/(theta)) for isopropylbenzene (971 - 1151K), log(k/s('-1)) = 15.9 - (69.1/(theta)) for t-butylbenzene (929 - 1157K), log(k/s('-1)) = 15.3 - …

Power Determination For Mobile Mining Equipment., Gene Thomas Lineberry Jan 1982

Power Determination For Mobile Mining Equipment., Gene Thomas Lineberry

Graduate Theses, Dissertations, and Problem Reports (ETD)

A piece of mobile mining equipment must possess sufficient power to overcome normal resistances and also resistances whose prediction and quantification is much more difficult, such as those accompanying cyclic maneuvers and emergencies. These abnormal, highly variable resistances require a quantity of reserve power. The sum of reserve power, required power, auxiliary power, and ambient corrections represents the total power requirement. Reserve power is traditionally defined as "the additional power available to a vehicle for climbing grades and for acceleration." In this study, reserve power was redefined as "the power available to a vehicle in addition to that necessary to …

Motor Skill Acquisition As A Function Of The Post-Knowledge Of Results Delay Interval And Task Complexity., Jimmy Patrick Timmons

Graduate Theses, Dissertations, and Problem Reports (ETD)

Schmidt (1975) and Weinberg, Guy, and Tupper (1964) have expressed the expectation that post-KR delays in simple to complex motor tasks must increase as task complexity increases if the rate of acquisition is to be maintained. This study was an attempt to investigate that prediction. Nine treatment conditions were established by the interaction of three levels of post-KR delay with three levels of task complexity. Volunteer subjects (N = 10 for each treatment condition) were male undergraduate and graduate students at West Virginia University during the summer of 1979. Twenty trials were received by each subject; the first ten were …

Electromagnetic Geophysical Tomography Incorporating Refraction And Reflection., Roger Dale Radcliff

Graduate Theses, Dissertations, and Problem Reports (ETD)

An accurate technique for remotely determining the internal structure of an object or underground environment would have a significant impact in mining, geoexploration, and the life sciences. This process of resolving the intrinsic properties of an object or environment by the transmission of X-rays or electromagnetic waves through the unknown anomaly is known as reconstructive imaging or tomography. Several efforts have been made to apply tomographical methods to electromagnetic measurements taken between two boreholes on either side of an unknown geophysical structure. However, it became necessary, because of the nature of existing reconstruction methods, to assume a straight-line propagation path …

Ion-Exchange Properties Of Chemically And Physically Modified Graphite., Thomas Matthew Matviya Jan 1982

Ion-Exchange Properties Of Chemically And Physically Modified Graphite., Thomas Matthew Matviya

Graduate Theses, Dissertations, and Problem Reports (ETD)

Organic compounds capable of ion-exchange were adsorbed on granular graphite. The ion-exchange capacity of the graphite modified in this manner was found to be limited to (DBLTURN) 10('-6) eq/g of graphite by the available surface area of the graphite. Acidic surface oxides on the graphite interfered with the determination of the contribution of the adsorbed organic compounds to ion-exchange. An electrically conductive ion-exchange medium was developed by partially oxidizing granular graphite with strong oxidizing agents. The reaction of graphite with K(,2)Cr(,2)O(,7) in concentrated H(,2)SO(,4) was extensively studied. The ion-exchange capacity of the oxidized graphite for H('+) and divalent metal ions …

The Rebec: An Orthographic And Iconographic Study. (Volumes I And Ii)., Margaret Anne Downie

Graduate Theses, Dissertations, and Problem Reports (ETD)

Most musical instruments of Western European culture have been studied and defined; however, no systematic study has yet been made for the instrument commonly known as the rebec (or rebeck). General reference sources and musicological studies which mention the rebec often provide discrepant, vague, and erroneous information. The current interest in the performance of Medieval and Renaissance music and the reproduction of instruments upon which this music might have been played has created a need, among performers and instrument makers, for specific, primary source information concerning the rebec. The use of the rebec in Western Europe can be documented through …
