Graduate Theses, Dissertations, and Problem Reports (ETD)
The second section of the questionnaire assessed West Virginia Home Economists about a number of items affecting the future of home economics„ A majority supported the notion that home economics should emphasize energy management and about half of them believed this involvement would have great social impact. WVHEA respondents were not united on the idea of integrating knowledge from several disciplines as compared to strengthening specialization. They were divided on the idea of using process problem analysis and solutions in lieu of the specialized, subject matter approach to content. The WVHEA respondents agreed solidly that food and clothing labs should …

The Kootenay Plains (Alberta) Land Question And Canadian Indian Policy, 1799-1947., John William Larner
The Kootenay Plains (Alberta) Land Question And Canadian Indian Policy, 1799-1947., John William Larner
Graduate Theses, Dissertations, and Problem Reports (ETD)
This paper contends that the Stoney (Assiniboine) people of southwestern Alberta, Canada, have a legitimate aboriginal claim to areas in the North Saskatchewan River headwaters known as Bighorn and Kootenay Plains, located between the first range of the Rocky Mountains and the Alberta-British Columbia boundary. The Stoneys appear to have followed two routes during their eighteenth-century westward migration from southeastern Manitoba. One group moved southwestwardly to central Montana, turning northward into the Alberta Rockies; while the other seems to have travelled along the prairie-parkland fringe, entering the mountains west of Edmonton, with one band taking possession of the upper North …

Earnings, Health, Safety, And Welfare Of Bituminous Coal Miners Since Theencouragement Of Mechanization By The United Mine Workers Of America., John Peter David
Graduate Theses, Dissertations, and Problem Reports (ETD)
The United Mine Workers of America began encouraging mechanization and concentration in the coal mining industry immediately after the end of World War II. The coal industry was in danger of losing primary markets, such as home heating and the railroads, and in order to obtain new markets, a competitive relationship with other basic fuels had to be assured. The various actions that the union encouraged were a restructuring of the industry so as to create more efficient and concentrated production units; higher wage rates and mine mechanization so as to assist the industry in obtaining greater volume at lower …
A Comparison Of The Effects Of Acute And Subacute Inhibition Of Cholinesterase On The Sensitivity Of Rat Tissues To Drugs, Dennis Joseph Foley
A Comparison Of The Effects Of Acute And Subacute Inhibition Of Cholinesterase On The Sensitivity Of Rat Tissues To Drugs, Dennis Joseph Foley
Graduate Theses, Dissertations, and Problem Reports (ETD)
This study was undertaken to further define the characteristics of subsensitivity produced by chronic administration of cholinesterase inhibitors and to attempt to elucidate a possible mechanism by which it occurs. Administration of disulfoton, echothiophate , parathion and OMPA to rats for eight days resulted in a decreased sensitivity of segments of ileum to carbachol and a marked inhibition of both true and total cholinesterase. The results indicate that a relationship between the degree of subsensitivity and the extent of cholinesterase inhibition may exist.

A Study Of The Oxidation Of Benzyl-Alcohols In Dmso (Methyl-Sulfoxide) And Of The Thermal Decomposition Of Dmso (Methyl-Sulfoxide)., David Lynn Head
Graduate Theses, Dissertations, and Problem Reports (ETD)
In all of the alcohol oxidations referred to previously, the alcohol was converted to some other substance (e.g., to tosylate, halide) before reaction with DMSO. Many alcohols, however, have been allowed to react with DMSO without prior conversion.⁴⁹ Traynelis et al. found that dehydration was the usual result when secondary and tertiary benzylic alcohols or tertiary aliphatic alcohols were heated at 160–185° in DMSO for nine to sixteen hours (equations 53 and 54). The dehydration of eleven alcohols was reported, and evidence suggested a carbonium ion mechanism.⁵⁰ A subsequent modification of reaction conditions permitted the dehydration of alcohols previously found …

An Examination Of Nonverbal And Verbal Instructional Guidelines In Students Developing Abstract Understanding Of Technical Concepts., Everett Nelson Israel
Graduate Theses, Dissertations, and Problem Reports (ETD)
At the present time, coherent optical sources exist as discrete components rather than as fully integratable systems. Thus the most pressing problem in the area of integrated optics is the coupling problem: How to excite and, subsequently, recover optical signals which are processed in an integrated circuit. This input and output coupling must be done efficiently.

Petrology And Stratigraphy Of The Greenbrier Limestone And Upper Pocono Sandstones, Wayne And Lincoln Counties, West Virginia., Bernard Robert Henniger
Graduate Theses, Dissertations, and Problem Reports (ETD)
A petrographic and stratigraphic study of the Middle Mississippian Greenbrier Group ("Big Lime") and associated units of southwestern West Virginia was undertaken by using 879 thin sections from 15 wells, 633 drillers' logs, and 66 mechanical logs. The "Big Lime" of southwestern West Virginia was deposited in a shallow- shelf, shoaling environment following slow transgression of the subtropical Greenbrier seas over a Pocono-Maccrady, deltaic-tidalflat complex. Regressive-transgressive fluctuations caused shoaling during lower to middle Union time, producing halo and crestal type oolite accumulations over Maccrady topographic highs. Biosparites were intimately associated with the shoal areas. Deepening of waters upon continued transgression …

Equivalence Of Personality Structure In Leary's Interpersonal System Of Diagnosis., James Leroy Truckenmiller
Equivalence Of Personality Structure In Leary's Interpersonal System Of Diagnosis., James Leroy Truckenmiller
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Leary system of interpersonal diagnosis was introduced in its entirety during 1957 as a descriptive alternative to traditional psychiatric assessment involving interpersonal behavior. It attempts to provide a conceptual and measurement framework by removing rating discrepancies among data sources from the realm of undesirable distortions vis-a-vis "True" traits, and by relating these discrepancies to processes such as conflict and identification in an operational fashion. The basic premise supporting operational definitions such as conflict and identification requires that the structural interrelations of interpersonal variables be similar regardless of the data source from which obtained. If this premise were to hold, …

Thomas Randolph: An Elizabethan In Scotland., Katharine Pitman Frescoln
Graduate Theses, Dissertations, and Problem Reports (ETD)
There has long been a need for a study of Thomas Randolph who served intermittently as Elizabeth's agent (later as ambassador) in Scotland between the years I? 59 and 1586. This is a detailed study (in narrative style) of his involvement in Scottish affairs, based primarily on original manuscripts (largely found in the British Museum and the Public Record Office, London). Most of his letters are calendared and are readily available; thus they have been heavily relied upon for Anglo-Scottish studies. Unfortunately, some of the abstracts are inaccurate, misleading, or inadequate. Consequently, there have been misinterpretations. Moreover, Randolph is merely …

Changes In The Sensitivity Of The Rat Heart To Drugs After Chronic Cholinesterase Inhibition., Sharon Eva Corey
Changes In The Sensitivity Of The Rat Heart To Drugs After Chronic Cholinesterase Inhibition., Sharon Eva Corey
Graduate Theses, Dissertations, and Problem Reports (ETD)
This study was undertaken to investigate the phenomenon of subsensitivity which occurs after repeated administration of an organophosphorus cholinesterase inhibitor. This manuscript has provided evidence to suggest that subsensitivity is not the result of qualitative changes in the cholinergic receptor or changes in the nerve endings. The author has suggested that a change in the number of receptors might be responsible for subsensitivity which is produced by chronic cholinesterase inhibition.

A Taxonomic Study Of The Ericaceae Of The Southern Appalachian Highlands., Doyle Stewart Blauch
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Southern Appalachian Highlands represent a unique geographical region in which to study plants. The Ericaceae, especially well developed in this region, are a family of plants which have long been of interest to man. At the present time there exists no adequate treatment of the Ericaceae of this particular area. The present study, based mainly upon examination of herbarium specimens and supplemented by studies in the field, attempts to correlate these findings with all the scattered published information concerning the genera of this family in the Southern Appalachians. More than 12,000 sheets of specimens from twenty-nine herbaria were examined …
