Derivatives Of Trifluorovinylsulfur Pentafluoride And F-(Tert-Butyl) Hypochlorite, Jo Ann Marie Canich
Derivatives Of Trifluorovinylsulfur Pentafluoride And F-(Tert-Butyl) Hypochlorite, Jo Ann Marie Canich
Dissertations and Theses
Trifluorovinylsulfur pentafluoride dimerizes to (SF5CFCF2)2 in the presence of cesium fluoride. Two derivatives of trifluorovinylsulfur pentafluoride, SF5CF(CF3)C(O)F and SF5CF(CF3)C(O)NH2, were used to prepare the new compounds, SF5CF(CF3)CO2H and SF5CF(CF3)CN, respectively. The first was prepared by reacting the SF5-acid fluoride with water, while the second involved the abstraction of water from the SF5-amide using P4O10. The attempted preparation of a bis-pentafluorosulfur ketone and a pentafluorosulfur containing acid anhydride …
High Valent Chromium (V) And Chromium (Vi) Complexes, Harry Bennett Davis
High Valent Chromium (V) And Chromium (Vi) Complexes, Harry Bennett Davis
Dissertations and Theses
A new preparative route to the only neutral chromium(V) oxide fluoride, chromium oxide trifluoride, has been accomplished by the reaction of xenon difluoride with chromyl fluoride at high temperature. The chromium oxide trifluoride is produced as crystals which are suitable for single crystal studies. In reactions of chromium oxide trifluoride with alkali and alkaline metal fluorides in anhydrous hydrogen fluoride, new chromium(V) oxide fluoride salts were obtained; these salts were not of high purity due to unknown problems. An attempt to prepare chromium oxide tetrafluoride by the reaction of xenon difluoride with chromyl fluoride in anhydrous hydrogen fluoride failed to …

Fort Ross: Russian Colony In California, 1811-1841, Kathryn E. Mitchell
Dissertations and Theses
The essential objective of this study was to fill a bibliographic void of secondary source material concerning Russian California. This was accomplished by combining available translations and more specific studies on the subject into one extensive work. Introductory chapters provide: (1) a brief statement regarding Russia's massive eastward expansion through Siberia, to Kamchatka and Alaska; (2) an examination of the nature of the Russian-American Company; and (3) a detailed look at the programs instituted by the Company to provision Alaska and Kamchatka. The establishment of Fort Ross in 1811 is viewed as one of those programs. The settlement's primary function …

Domestic violence has received increasing attention in recent years as an area of concern for the helping professional. Despite this interest, programs for counseling the batterer are relatively few and counseling interventions for use with this client population are in what could be termed an experimental phase. The purpose of Counseling the Batterer is to review the pertinent literature concerned with counseling the batterer, to explore several programs which have been involved in this effort, and also to design a model group counseling program for abusive males. The foundation for the model program is based on the pertinent literature and …
Inquiry Into The Causes And Significance Of Cytoplasmic Vacuolation Of Neutrophils In The Peripheral Circulation, Gary Xavier Haight
Inquiry Into The Causes And Significance Of Cytoplasmic Vacuolation Of Neutrophils In The Peripheral Circulation, Gary Xavier Haight
Dissertations and Theses
One-half million cases of septicemia are reported annually with a mortality of around 35%. Diagnosis depends in part on blood cultures which require one to two weeks. It would be advantageous if an early sign of septicemia were available.
Cytoplasmic vacuolation of polymorphonuclear neutropnils is occasionally seen in the peripheral blood smears of patients who have infections. The object of this work was to determine the cause and significance of cytoplasmic vacuolation with the goal of using the occurrence of vacuolation as an early indicator of infection.

Developmental Sentence Scoring: A Comparative Study Conducted In Portland, Oregon, Kathryn Marie Mccluskey
Developmental Sentence Scoring: A Comparative Study Conducted In Portland, Oregon, Kathryn Marie Mccluskey
Dissertations and Theses
The purpose of this investigation was to replicate the study conducted by Lee and Canter (1971) and Lee (1974a) to determine if a significant difference among the scores in the two studies existed due to geographical location, and to initiate the establishment of norms for the Portland, Oregon geographical area. Forty children, selected on the basis of chronological age (4.0 to 4.11 years), normal receptive vocabulary skills, normal hearing, and a monolingual background, participated as subjects. A language sample of fifty utterances was elicited from each child and analyzed according to the Developmental Sentence Scoring (DSS) procedure.
A Comparison Of Measures Of Emotions From Written Reports Of Dreams And Waking Experiences, Edward D. Conklin
A Comparison Of Measures Of Emotions From Written Reports Of Dreams And Waking Experiences, Edward D. Conklin
Dissertations and Theses
Various researchers have noted that emotions expressed in dream reports are infrequent and, more often, unpleasant. These observations are ambiguous for several reasons: (1) Empirical opinions differ markedly with regard to the structure of mentation across the continuum of waking and sleeping experience. (2) While the waking state is usually assumed as an implicit baseline, few studies have quantitatively compared waking and dream emotions. (3) Dream researchers have not thought about the basic nature of emotions or certain constraints which sleep physiology might impose upon emotions. In light of these assertions and considerations, an intrasubject comparison of emotions in reports …
Tiltmeter Analysis Of Mount St. Helens, Skamania County, Washington, Edward Charles Brown
Tiltmeter Analysis Of Mount St. Helens, Skamania County, Washington, Edward Charles Brown
Dissertations and Theses
Mount St. Helens returned to an active eruptive state March 20, 1980. Since then explosive and dome building eruptions have caused major topographic changes to the mountain and surrounding drainages. Monitoring of the southern side of the mountain by six tiltmeters at distances between 6 km and 12 km was conducted during the period of July 1, 1980 to December 31, 1980. Records obtained from the tiltmeters were analyzed and compared to data from precision geodetic surveys.

Evaluating Urban Containment Programs, Arthur C. Nelson
Evaluating Urban Containment Programs, Arthur C. Nelson
Dissertations and Theses
Urban containment programs may be evaluated in terms of a theory unifying contributions from the economic, geographic and political science disciplines. The unified theory shows that successful programs will segment the urban-rural land market, remove speculative use value of rural land, and result in the urban land market valuing greenbelt proximity as an amenity. A general model to test urban containment programs against the unified theory is developed and then modified for application to Salem, Oregon. Results are fourfold. First, a gap in the locus of urban and rural land values at the UGB indicates that segmentation of the urban-rural …
The Outcomes Of A Quality Circle Program In An Electronics Manufacturing Firm, Martin L. Abbott
The Outcomes Of A Quality Circle Program In An Electronics Manufacturing Firm, Martin L. Abbott
Dissertations and Theses
The literature on worker participation generally assumes that worker participation programs lead to positive work outcomes (e.g., job satisfaction) in more or less direct fashion. The current study challenges this assumption and posits that "desire for participation," and "attitudes toward participation," may affect the participation-satisfaction relationship. Data were gathered from a quality circle (QC) program at a large electronics manufacturing firm, using both quantitative (survey questionnaire), and qualitative (interviews, observation, meeting attendance) means. QC members and non members were compared on all attitude measures, and on general job satisfaction. The results indicated the following: (a) the participation-satisfaction thesis was not …

Over 1150 m of middle to late Eocene nonmarine arkose, lithic arkose, mudstone, and siltstone, referred to here as the Chambers Creek beds, are int~r.stratified with, and overlain by over 1600 m of late Eocene-Oligocsne(?) andesitic volcaniclastic and subordinate volcanic rocks assigned to the Ohanapecosh Formation, in a dissected structural high in the southern Washington Cascade Range, about 18 km south-southeast of the town of Packwood.
Determination Of Toluene's Degradation Products Under Simulated Atmospheric Conditions, Bruce E. Dumdei
Determination Of Toluene's Degradation Products Under Simulated Atmospheric Conditions, Bruce E. Dumdei
Dissertations and Theses
The reactions of aromatic hydrocarbons represent a major area of uncertainty in urban atmospheric photochemistry. Much effort has been spent studying the simulated atmospheric oxidation chemistry of model aromatics, such as toluene, in order to delineate their reaction mechanisms. These studies are motivated both by interest in fundamental processes and a desire to discover an aromatic's contribution to the formation of ozone in polluted ambient atmospheres. Previous work on toluene includes both product studies and proposed mechanisms. In all previous studies, the combined product yields are half or less of the initially reacted toluene. A major reason for the poor …
The Role Of The Family In Delinquency Causation: An Interactional View, James W. Burfeind
The Role Of The Family In Delinquency Causation: An Interactional View, James W. Burfeind
Dissertations and Theses
American society traditionally has held the family responsible for the socialization and social control of children, and when youngsters get into trouble the causal finger of blame is pointed at the family. No wonder then that a recurrent issue within the study of delinquent behavior has been the precise etiological role of the family. This thesis begins with an historical examination of the different approaches taken in the sociological study of delinquency and the family. This research investigated whether "interactive effects" are important in conceptualizing and understanding the family's etiological role. The concept of interaction is based upon the assumption …
Fringe Area Growth In Metropolitan Portland: An Analysis Of Space-Time Variations In Residential Housing And Land Conversion, 1970-1980, Sheku Gibril Kamara
Fringe Area Growth In Metropolitan Portland: An Analysis Of Space-Time Variations In Residential Housing And Land Conversion, 1970-1980, Sheku Gibril Kamara
Dissertations and Theses
Urban ecological problems have hitherto been addressed using one of two major approaches. The first has a social impetus directed at ethnic, economic and family characteristics and their relationships with the spatial distribution of urban residential housing. The second approach emphasizes the influence of the physical environment and the services available to subareas. The sociological method has had much more attention in modeling applications than the physical analytic technique. This study adopts the physical approach with a focus that is emphatic on infrastructural factors and land attributes, and their influence on the differential rates of fringe area residential growth in …
The Political Unification Of The Israeli Army, Michael Uhry Newman
The Political Unification Of The Israeli Army, Michael Uhry Newman
Dissertations and Theses
The essay charts forty years of Zionist history to illuminate the remarkable evolution of Israel's unified, apolitical army and Israel's "democratic civil-military tradition," forged in the fires of opposing military styles, ideological rivalry, competing underground forces, war and civil war.
Stepfamily Adjustment: A Balance Theory Analysis Including The Noncustodial Parent As A Member Of The Family System, Margaret L. Fujita
Stepfamily Adjustment: A Balance Theory Analysis Including The Noncustodial Parent As A Member Of The Family System, Margaret L. Fujita
Dissertations and Theses
This study developed a balance theory analysis of stepfamily relationships in order to understand family adjustment and empirically tested hypotheses derived from that analysis. Sentiment and unit relations between the stepparent, natural parent, and adolescent child, and between these stepfamily members and the nonresident (absent) natural parent were included in the analysis. The assumption of balance theory is that sentiment (affective) relations and unit relations (the perception of belonging together) tend toward a balanced state. If a balanced state does not exist, the imbalance will produce tension. The general hypothesis tested was that the degree of balance of the stepfamily …
Retirement Satisfaction And The Timing Of The Retirement Age: An Analysis Of Retirees And Older Workers From A Fortune 500 Firm, Donna Elaine Stuteville
Retirement Satisfaction And The Timing Of The Retirement Age: An Analysis Of Retirees And Older Workers From A Fortune 500 Firm, Donna Elaine Stuteville
Dissertations and Theses
This study focuses the effects of demographic characteristics, health status, income, work attitudes, and leisure activity involvements have on satisfaction in retirement and the retirement timing decision. The review of the literature revealed that no single variable alone is the predictor of retirement satisfaction and the timing of the retirement decision. Therefore, a conceptual model was developed to measure the two central research questions. The conceptual model is based on five categorical factors as the determinants of retirement satisfaction and timing. The five main factors in the model are: demographic characteristics, health status, income level, work attitudes and leisure activity …
A Theoretical And Experimental Examination Of Sodium Chloride Hydration, Debra Conway Modra
A Theoretical And Experimental Examination Of Sodium Chloride Hydration, Debra Conway Modra
Dissertations and Theses
A Hitachi Hu 125C transmission electron microscope in which the standard specimen holder was replaced by an environmental cell was used to observe the hydration of sodium chloride crystals. To observe Kelvin curvature and solubility effects sodium chloride crystals which were 0.1u or smaller were of special interest. An electrohome video system attached to the electron microscope was used to record the sodium chloride hydration for subsequent particle measurement and viewing.
A theoretical model was also developed. Thermodynamic properties such as the Kelvin curvature and solubility effects were considered as well as the kinetic expressions for salt dissolution/recrystalization and water …
Spies In America : German Espionage In The United States, 1935-1945, Joan Irene Miller
Spies In America : German Espionage In The United States, 1935-1945, Joan Irene Miller
Dissertations and Theses
This thesis addresses the topic of German espionage in the United States between 1935 and 1945. It examines what the expectations were for Germany's spies in America, their activities, and the success or failure of their operations. In addition, the reaction of the American public to these spies is also studied, as well as the response to what was perceived as a threat to the United States from Nazi Germany.
Forecasting Interest Rates Using Pattern Recognition Techniques, John S. Pearson
Forecasting Interest Rates Using Pattern Recognition Techniques, John S. Pearson
Dissertations and Theses
Much depends on the future course of interest rates. The decisions of families to make major purchases, the willingness of businesses to expand and invest, the rise and fall of the economy and stock market, the ability of lesser developed countries to repay their debts, the tenure of presidents and prime ministers--all of these may turn on whether interest rates increase or decrease in the months ahead. Several decision functions developed in the dissertation permit the direction of change of interest rates on long-term U. S. government bonds to be forecast correctly about 60% of the time. When the different …

Urban Housing Policy Evaluation In The Kingdom Of Saudi Arabia, Tarek Ali Fadaak
Dissertations and Theses
The rise in wealth for the Kingdom of Saudi Arabia led to an increase in demand for more and better housing. In response to this rising demand, and as part of an overall development policy, a housing 60a1 and several housing objectives were identified. To attain the goal and objectives, a formal housing policy was designed and authorized. It involved direct and indirect assistance to the private sector, a subsidized financing program for new housing construction, a serviced land program for the low income, and public housing. This thesis is an evaluation of the urban housing policy in the Kingdom …
The Contribution Of Social Support To The Successful Functioning Of Men With Epilepsy, Diane L. Pancoast
The Contribution Of Social Support To The Successful Functioning Of Men With Epilepsy, Diane L. Pancoast
Dissertations and Theses
One hundred men with epilepsy were interviewed about the history of their illness, employment history and personal support network. Included as sources of support were: household members, close friends and relatives, more distant relationships and general forms of social participation such as church membership. Four potentially supportive aspects of these relationships were assessed: structural features of the pattern of relationships; characteristics of the individual ties; exchanges of helping resources and subjective assessments of the supportiveness of ties. The social support networks of the men who were satisfied with their lives were large, diverse, active and generally helpful. Church membership was …
An Investigation Of The Relationship Between Biographical Characteristics And Job Satisfaction Among Middle School Teachers In Four Suburban School Districts, Susan Scott-Miller
An Investigation Of The Relationship Between Biographical Characteristics And Job Satisfaction Among Middle School Teachers In Four Suburban School Districts, Susan Scott-Miller
Dissertations and Theses
Quality Circles (QC) took root in Japan during the 1960s and was introduced into the U.S. in 1974. Today, many people believe QCs can increase teacher and school effectiveness. Beyond the realm of opinion, however, little research supports this belief. This study had three purposes. The first was to review QCs' literature. The second was to identify QC structures and problem solving procedures. The third was to test QCs in an educational setting and to analyze their effects on the attitudes of teachers. Methodology. QC groups and comparison groups were established at four school sites. Two measurement instruments, the Work …
