Joseph Campbell's comparative studies in mythology revealed to him that culturally bred mythologies, despite their ethnic inflections, continually point to universal archetypes and a common human identity. Campbell's belief in the common human identity stems from his adherence to Carl Jung's mystical perspective on myth, where archetypes of the personal and collective unconscious help us understand humankind in the past, present and future. Myth, like art, Campbell believed, should be interpreted metaphorically, in terms of connotation instead of denotation. Failure to interpret myth poetically leads to religious, social, and political divisiveness. Examples of consequences of a literally interpreted mythology prevail in contemporary ethnic and global warring. This thesis examines the prominent themes in Campbell's alternative philosophy of mythology, and particularly the interpretation of some selected notions in Biblical mythology which, he suggests, have to be reviewed and re-interpreted metaphorically. With the collapse of cultural boundaries due to modernity, the world community needs a mythology for the whole planet. This thesis will discuss the serious implications for religious education of Campbell's hermeneutics of mythology.

Note:

Cellular cofferdams have primarily been used as temporary systems which serve to allow construction of facilities in open bodies of water. Applications for these structures have been increasing and today they may serve as permanent retaining walls or as navigation or waterfront structures. Conventional design methods for cellular cofferdams are based on semi-empirical approaches largely developed in the 1940s and 1950s. None of the available traditional procedures are capable of predicting cofferdam deformations, a parameter of key importance to the cofferdam performance, and which is often observed during construction for purposes of safety monitoring. Also, there is evidence that much of the conventional design technology is conservative, in some cases predicting loading by more than twice that which actually occurs. Recently, the finite element method has shown promise as a tool which can be used to help resolve some of the outstanding problems with cofferdam design. There are three primary objectives of this work: (1) enhance existing finite element program to allow for more accurate and refined analysis of cellular cofferdams, (2) use the enhanced finite element programs to assess the degree of conservatism in conventional design methods for cofferdams founded on sandy soils, and (3) use the results of parametric studies of cofferdams founded on sandy soils to develop a simplified procedure to predict cofferdam movements and determine potential for internal failure. The first of the objectives involves adding better bending elements to the program SOILSTRUCT to represent the sheet pile system In axisymmetric and plane strain analyses. Also, in the case of the plane strain program, a new method is developed to allow shear transfer through the sheet pile system. Through case history and theoretical analyses, the enhanced programs are demonstrated to yield accurate and realistic results. Parametric studies using the axisymmetric program show that conventional design methods overpredict, in some areas strongly, the interlock forces which develop during filling of the cofferdam. Parametric studies using the plane strain program suggest that there is also considerable conservatism in design methods to predict internal stability of the cofferdam. A new, simplified method is proposed for this type of analysis. In addition, it is shown that the deformations of cofferdams on sand follow consistent trends and can be set into a nondimensionalized context which can be used to predict future cofferdam movements. / Ph.

This work focused on the formation and the subsequent use of a difunctional organolithium as an anionic polymerization initiator for primarily diene monomers. The initiator was formed in nonpolar solvent such as cyclohexane and toluene by the addition of two equivalents of sec-butyllithium to one of the nonconjugated diene 1,3-bis(α-phenylethenyl)benzene. The disappearance of the starting diene was easily followed by UV/Visible spectroscopy. Rate expressions were evaluated based on the assumptions of a consecutive reaction mechanism and association behavior of the alkyl lithium. Arrhenius behavior was observed and an activation energy of 19 Kcal/mole was determined. Unlike the spectroscopic techniques, gas chromatography was able to separate the unreacted diene, mono-, and diaddition products but dramatic increases in sensitivity were realized by using a capillary column techniques, thus allowing the direct analysis of initiator solutions that were routinely used for high molecular weight polymerizations. Quantitative determination of all reaction components confirmed the existence of a consecutive reaction mechanism for this addition and the data strongly suggested that the second rate constant was an order of magnitude faster than the first in cyclohexane. Using the chromatographic technique to monitor initiator formation, the dianionic diaddition product was maximized by the simple addition of more sec-butyllithium. Polydiene homopolymers were then routinely prepared with predictable molecular weights and narrow polydispersities. Successive addition of isoprene and styrene resulted in triblock copolymers that incorporated both monomers over a wide compositional range. Novel triblock systems that contained t-butyl methacrylate end blocks and an isoprene center block were prepared by addition of THF which facilitated the efficient crossover. A new trialkyl sodium magnesiate initiator was evaluated as an alternative to alkyllithiums for the polymerization of vinyl and cyclic monomers. Homopolymerizations of isoprene and styrene showed slow initiation rates and uncontrollable molecular weights relative to sec butyllithium. This initiator also polymerized methyl methacrylate in high yields without modification of its basicity and steric bulk. / Ph. D.

Metamictization and complex chemistry are major obstacles to the crystal chemical characterization of natural allanites. To overcome these problems, allanites, Ca(REE)Fe²+Al₂Si₃O₁₂(OH), where REE = La, La-Ce, Ce, Nd, Sm, Eu, Gd, Er, Dy, Yb and Y have been synthesized hydrothermally from unbuffered and buffered oxide mixes at 500 to 650°C, 5.5 kbar (550 MPa), and 700 to 725°C, 4 kbar (400 MPa). Although allanite is readily synthesized, high yields are obtained only for allanite-(LREE) compositions, and end"member composition is obtained only for allanite-(La). Er and Yb ions are too small to substitute at the A(2) site in allanite, but a small amount can substitute at the VI~coordinated M(3) site. Fe²+ in the M(3) site favors LREE substitution, which supports the contention that allanite is Ce'selective. / Ph. D.

The results of substitution of A (with A = Ni and Zn) for Cu are presented in the high Tc superconductors, YBa₂(Cu_{1 - x}A_x)₃O_{6 + δ} where x < 0.03 for Zn and x< 0.10 for Ni. We have observed that the superconducting temperature in the high Tc YBa₂Cu₃O_{6 + δ} as system decreases if copper is substituted by Ni and Zn and the substitution of Zn affects Tc much more than Ni. We discuss our results in terms of pair breaking by magnetic impurities and in terms of the Resonance Valence Bond model proposed by Anderson. / Master of Science

This work presents a design process for developing a dedicated hybrid thick-film time domain reflectometer. The design process allows for variation of the pulse generator characteristics as well as the output impedance of the unit. The unit is fabricated using standard thick-film hybrid techniques while giving consideration to problems encountered at microwave frequencies. This thesis also presents an overview of time domain reflectometry and its applications. Special emphasis is given to the problem of characterizing material dielectric constants using delay measurements. / Master of Science
