DNA-DNA hybridization experiments were used to examine the genetic variation that has accumulated with the North American Biological Species (NABS) of Armillaria. Forty strains including nine of the ten NABS and A. tabescens were used in this study. The normalized percent hybridization values ranged from 80%-100% similarity within a given biological species and ranged from 30%-85% among the biological species, The NPH data was summarized with UPGMA clustering analysis to give four main clustering groups, two were homogeneous and two were heterogeneous, The first included A. tabescens; the second included A. mellea; the third included A. calvescens, A. gallica, A. sinapina, NABS IX, and NABS X; the fourth included A. gemina and A. ostoyae. One cluster of two A. gallica strains shared greater similarity with NABS X than it had to four other conspecific strains, The NPH data and estimates of genome size (genetic complexity) was analyzed using a stoichiometric approach to calculate equivalents of homologous DNA and low copy repetition frequencies. Reciprocal NPH values did not predict relative genome size as expected, However, as the relative genome size increases, the equivalents of homologous DNA increases in the same proportion. This suggests that as an Armillaria genome increases in total complexity (novel sequences), certain ancestral sequences are duplicated in proportion the increase in total genetic complexity, This interpretation of the data is discussed with respect to interspecific hybridization, diploidy, and chromosomal evolution including alloploidy, aneuploidy, and chromosomal length polymorphisms.<br>Ph.

This thesis investigates the relationships between projects in the form of resistance. The thesis is accompanied by a series of projects that investigate a number of resistances. These resistances spur relationships to other works in progress; descendents. The projects are a testing ground for the ideo-logical content in an architects work. Each project we undertake is a part of a much larger whole that may or may not be a life's work, but is, certainly, an influence in the creation of coherence as we move forth in our practice. This is not to say that everything must look alike, rather it is to keep one involved in the fundamental aspects of a project that may give clues as to what you as an architect stand for. It is itself a resistance to the problems facing us as we attempt to build. Those problems that may begin to bog us down and force us to lose sight of architecture. There are many things on one's plate as a project proceeds, it is not easy to keep focus. The architect must seek aspects that put us into dialogue with those things outside that inevitably influence the specific work at hand. A way of arriving at conclusions that do not confound an architecture. I see it as being analogous to Hertzberger's discussion of warp and weft, a defined structure into which possibilities may be woven creating relationships between the elements of the architecture. This asserts a set of rules that an architect learns how to work with, and even violate. This formulation creates multiple possibilities within and outside a framework of the architect's order. The architect learns to question within the boundaries of his times, and perhaps beyond those bounds with that understanding. He learns what to ask and what not to ask; which resistances offer stimulus and which do not. The work, through time, acts as an analogue to history itself. The designer may then create with a better grasp of the full potentiality of Architecture.<br>Master of Architecture

The purpose of the current study was to investigate whether the separate contributors to procedural and distributive justice also affected the other form of justice. Previous research investigating these cross over effects of justice contributors had not examined inputs in addition to outcomes and procedures, and had typically assumed outcome level to be equivalent to the equitableness of outcomes. Subjects were 120 undergraduate psychology students. Outcomes, inputs and procedures were manipulated in a laboratory experiment in order to assess their independent and combined effects on distributive and procedural justice perceptions. In contrast to past research, the current study found a weak and inconsistent effect of procedures on distributive justice perceptions. Outcome level had a strong effect on both procedural and distributive justice perceptions. In addition, outcome fairness was found to effect procedural justice perceptions. When procedures were fair, the equitableness of outcomes influenced distributive justice ratings. When procedures were unfair, however, the equitableness of outcomes did not influence distributive justice judgements. Implications for procedural justice conceptualizations, equity theory and organizations are discussed.<br>Ph. D.

The addition of the lithium dienolate of ethyl crotonate to 2-cyclopentenone was studied to determine the stereochemical outcome of this Michael addition. Proof of the stereochemistry was provided via the unambiguous synthesis and comparison of ketone 73 from norcamphor 85.<br>Master of Science

Architecture lies in the relationship between material and structure, in particular the poetic of constructed form. By poetic, I am referring to, as Kenneth Frampton put it, "the original Greek sense of poesis as an act of making and revealing." Through the dialogue of constructive elements, materials, the making of form and the resolution of structural forces, beauty and meaning arise. "Tectonics" is defined as "pertaining to building or construction in general" especially in reference to architecture. Gottfried Semper went further to use tectonic to define the qualities of making inherent in the constructed act. He broke down types of construction into that of using elements for a framework, such as wood frame construction, and that of using compressive mass to build an enclosure, such as block or stone work. The qualities of these he called "tectonics" and "stereotomics," respectively. Frampton discusses the ontological consequences of these differences: "framework tends towards the aerial and dematerialization of mass, whereas the mass form is telluric, embedding itself deeper in the earth. One tends toward the light and the other toward dark. These gravitational opposites . . . may be said to symbolise the two cosmological opposites to which they aspire; the sky and the earth." Human existence finds itself at the juncture between these opposites. Semper regarded the joint as "the primordial tectonic element" around which all building defines itself. Then in a sense architecture embodies the fundamental way man perceives his existence.<br>Master of Architecture
