Mixed Alkyllithim/Lithium Alkoxide Aggregates with Less Sterically Crowded Alkyl Groups (open access)

Mixed Alkyllithim/Lithium Alkoxide Aggregates with Less Sterically Crowded Alkyl Groups

Mixed alkyllithium / lithium alkoxide aggregates in the form (RLi)n(ROLi)m were formed by addition of corresponding alcohol compounds at different Li/O ratios. Variable temperature 13C and 6Li NMR spectroscopy were used to verify the formation of the mixed aggregates and to study their behavior in hydrocarbon solution. Spectra for the lithium n-propoxide / n-propyllithium and iso-butyllithium / lithium iso-butoxide systems each indicated at least one mixed aggregate.

New Adventures in the Chemistry of Polycarboncyclic Ring Systems (open access)

New Adventures in the Chemistry of Polycarboncyclic Ring Systems

I. Diels-Alder reactions of 1,2,3,4,9,9-hexachloro-1,4,4a,8a-tetrahydro-1,4-metha- nonaphthalene (16) and 1,2,3,4,9,9-hexachloro-1,4,6,7-tetrahydro-1,4-methanonaphthalene (17) toward dienophiles N-methyl-1,2,4-triazoline-3,5-dione (MTAD), N-phenyl-1,2,4-triazoline-3,5-dione (PTAD) and/or N-methylmaleimide (NMM) have been examined. II. Epoxides derived from functionalized 1,4,4a,9a-tetrahydro-9,10-dioxo-1,4-methanoanthracenes (1a and 1b) undergo acid- and base-promoted intramolecular nucleophilic ring-opening to form new polycyclic alcohols. III. The title cycloalkylidenecarbene has been generated via reaction of 8-methylenepentacyclo[5.4.0.0^{2,6}.0^{3,10}. 0^{5.9}]undecan-11-one (44) with diethyl diazomethyl-phosphonate (DAMP). This species could be trapped in situ by cyclohexene, thereby affording the corresponding cycloadduct 46a and 46b.

Expectation as Narrative Strategy in Richard Wagner's Parsifal (open access)

Expectation as Narrative Strategy in Richard Wagner's Parsifal

The story of Parsifal is presented in two manners: through action and through narrative. Using the formalist theories of Vladimir Propp, the overall narrative is articulated in three narrative episodes. This thesis interprets the structure of narrative episodes in Parsifal on the basis of expectation. Propp's theory of functions provides labels for an interpretive analysis. Levi-Strauss' reconstruction of Propp's functions into paired structures identifies key points in the drama as moments of "functional" saturation. This "functional" saturation coincides with Wagner's practice of Leitmotivic saturation. The semiotic theories of Charles Sanders Peirce, specifically his notion of sign, clarify the dense accumulation of meanings accrued by the Leitmotifs. Finally, Parsifal, as a "quest" for the unobtainable object, fits into the matrix of desire as formulated in the theories of Jacques Lacan.

A Study of the Relationships among Student Expectations about Teacher Nonverbal Immediacy, Student Perceptions of Teacher Nonverbal Immediacy, and Affective Learning in Distance Learning and the On-Site Classroom (open access)

A Study of the Relationships among Student Expectations about Teacher Nonverbal Immediacy, Student Perceptions of Teacher Nonverbal Immediacy, and Affective Learning in Distance Learning and the On-Site Classroom

This thesis explored the relationships among three communication variables in college-level instruction: students' expectancy about teachers' nonverbal immediacy, students' actual perceptions of teachers' nonverbal immediacy, and students' affective learning. Community college students enrolled in either distance learning or a traditional classroom course completed pre-course and mid-course questionnaires to indicate their expectations and observations of the nonverbal immediacy behaviors of their teachers. Analysis showed that students expected and perceived less nonverbal immediacy from tele-course teachers than from on-site teachers, but that perceptions significantly exceeded expectations. Research findings indicated that students' expectancies about teachers' nonverbal immediacy may influence the measurement of affective learning.

The Emergence of a New Capitalist Ethic: Transformational Leadership and the Civil Society Movement as Emergent Paradigms Affecting Organizational and Societal Transformation (open access)

The Emergence of a New Capitalist Ethic: Transformational Leadership and the Civil Society Movement as Emergent Paradigms Affecting Organizational and Societal Transformation

Rapid and chaotic changes in market environments have caused business organizations to modify their organizational structures and social relationships. This paper examines the change in relationship between management and employees, which is shifting from an adversarial and controlling role to facilitation and employee empowerment. This paper's research question concerns how classical sociological theory would explain power redistribution within organizations and the formation of an associative and collaborative relationship which contradicts traditional paradigms. Traditional bureaucratic and contemporary organizational forms are compared and contrasted. Organizational climate, psycho-social components of underlying assumptions and group ethics are seen to be the mechanisms impelling transformation. Organizational change is driven by an emerging secular ethic. This ethic is embodied in an applied model of leadership and examined as an ideal type. The common ethic impelling organizational change is seen to be the same as that causing social transformation in both national and international spheres.

Evaluation of the Use of the Bivalves Ischadium recurvum Rafinesque, 1820 and Corbicula fluminea Muller, 1774 as Biological Indicators of Relative Water Quality in Terms of Growth and Upper Temperature Tolerance (open access)

Evaluation of the Use of the Bivalves Ischadium recurvum Rafinesque, 1820 and Corbicula fluminea Muller, 1774 as Biological Indicators of Relative Water Quality in Terms of Growth and Upper Temperature Tolerance

Growth of mussels under laboratory conditions was examined under various food regimes in different water types and temperatures. Growth was less than would be useful as an indicator and comparisons with field exposures were of minimal value. The effects of organophosphates on bivalves were examined via toxicity tests, tissue concentration, and by controlling exposure through the use of physical constraints. Upper temperature tolerance of both bivalve species was examined with respect to different acclimation temperatures and organophosphate exposures. Deviations from control exposures occurred at some temperatures. Copper effectively lowered the mean heat coma temperatures of C. fluminea at some concentrations, however, chlorine exposures did not alter heat coma temperature.

The Desires of Rebecca Horn: Alchemy and the Mechanics of Interpretation (open access)

The Desires of Rebecca Horn: Alchemy and the Mechanics of Interpretation

The purpose of this thesis is to analyze the use of alchemy within the work of Rebecca Horn, to elucidate its presence in her work, and to illuminate its purpose as a personal philosophy and as a creative tool. The use of alchemy within Horn's work occurs as a process of revelation and transformation. Alchemy is revealed as a spiritual philosophy and as an interpretative system through the changes that occur in Horn's oeuvre. Throughout Horn's career, alchemy has developed into an interpretive system, a type of spiritual and cosmic perspective, that allows the artist to study, access, and meld diverse realities (sacred and profane) and diverse social systems (religious and scientific) into a more holistic and spiritually infused reality for herself and society-at-large. The purpose of her work is to help reinvest contemporary life with a spiritual presence by offering a model and a means of bringing the sacred into the profane.

Mobiles (open access)

Mobiles

Mobiles is a composition for an ensemble consisting of 12 instruments. The piece, in one movement, incorporates intuition, chance, and twelve tone techniques and reflects the relationship between motion and rest or tension and release. The structure is modeled according to principles of growth and decay, starting off slowly, building, and then dying away. Much of the material is inspired by mental images invoked from modern theories concerning chaos. Mobiles' character stems from the principal use of two motives, the chaos motif and the echo motif. Primarily, the chaos motif is representative of a state of motion while the echo motif represents a state of rest. Mobile architecture is usually characteristic of symmetry, balance, and proportion, but because of uncertainty in a natural environment, this proportion often falls short of a perfect symmetrical balance as in the case of a crystal or a fractal design. It is this kind of architecture that Mobiles portrays in its form and developmental process.

Populism and the Poll Tax: the Politics and Propaganda of Suffrage Restriction in North Texas, 1892-1904 (open access)

Populism and the Poll Tax: the Politics and Propaganda of Suffrage Restriction in North Texas, 1892-1904

This thesis challenges the traditional interpretation of the history of Populism in America through the use of an intensive regional study. Using precinct-level returns, this thesis proves that, contrary to the conclusions of more general studies, voters from predominately Populist areas in North Texas did not support the poll tax amendment that passed in November 1902. The Populists within this region demonstrated their frustration and distrust of the political process by leaving the polls in higher percentages than other voters between 1896 and 1902. The Populists that did participate in 1902 reentered the Democratic Party but did not support the poll tax, which was a major plank within the Democratic platform. This thesis also proves that the poll tax had a significant effect in reducing the electorate in North Texas.

Political Culture in West and East Germany at the TIme of Reunification: Revisiting the Civic Culture (open access)

Political Culture in West and East Germany at the TIme of Reunification: Revisiting the Civic Culture

Studies of political culture have often focused on the impact of political institutions on political culture in a society. The scientific community has accepted the position that institutions shape beliefs and attitudes among the citizens towards the system they live in. This study tests this hypothesis by using survey data collected during the fall of 1990 in the United States, Great Britain, Italy, West, and East Germany.

Mobile Order Theory as Applied to Polycyclic Aromatic Heterocycles (open access)

Mobile Order Theory as Applied to Polycyclic Aromatic Heterocycles

Experimental mole fraction solubilities of benzil, thianthrene, trans-stilbene, thioxanthen-9-one, diphenyl sulfone and dibenzothiophene sulfone are determined in pure noncomplexing and complexing solvents. Predicted solubility values are calculated for benzil, thianthrene, trans-stilbene and thioxanthen-9-one using expressions derived from Mobile Order theory. Large deviations between experimental and predicted solubilities in alcohol solvents exist, therefore optimized solute - solvent association constants are determined. Previously measured thianthrene solubilities in five binary alkane + cyclohexane solvent mixtures are compared with values predicted from Mobile Order theory using the measured solubility in each of the pure solvents as input parameters. The experimental mole fraction solubility of benzil in eight binary alcohol + 1-octanol solvent mixtures are also measured and compared with predicted values.

Motivational Style, Length of Residency, and Voluntariness in Relation to Nursing Home Adjustment (open access)

Motivational Style, Length of Residency, and Voluntariness in Relation to Nursing Home Adjustment

This study related length of residency, motivational style, and the resident's role in deciding to move to a nursing facility to adjustment, represented by a number of variables (e.g., desired control, expected control, life satisfaction, and affect). Fifty-five residents of nursing facilities and assisted-living apartments were given an interview, compiled of a number of brief measures relating to aspects of adjustment. While results from multivariate analyses of variance failed to support any of the hypotheses, post-hoc univariate analyses of variance and regression analyses revealed important relationships between motivational style and voluntariness regarding the move and factors of adjustment. Overall, post-hoc findings indicated that, in the relatively constrictive environment of the nursing home, persons with a non-self-determined motivational style and persons who decided themselves to come to the nursing home had higher scores on various factors related to adjustment.

Elementary School Teachers' Responses to Potential Child Abuse (open access)

Elementary School Teachers' Responses to Potential Child Abuse

This study was designed to evaluate: (a) teachers' behavior when they are confronted with potential cases of child abuse and (b) the information teachers require to make accurate decisions regarding the reporting of suspected child abuse. Teachers were presented with three vignettes describing cases of varying levels of suspected maltreatment, and different amounts of additional information. They were then asked to indicate how likely they would be to report the case to Child Protective Services (CPS). It was expected that reporting behavior would increase as available information increased. The results generally did not support this hypothesis. No significant impact on reporting behavior was found when teachers were presented with either the symptom list or the legal interpretation; however, there was a trend toward an interaction with the level of abusive indications in the case. These results are discussed in the context of the need for further training.
