Comparative morphology of configurations with reduced part count derived from the octahedral-tetrahedral truss

Morphology (the study of structure and form) of the octahedral-tetrahedral (octet) truss is described. Both the geometry and symmetry of the octet truss are considered. Morphological techniques based on symmetry operations are presented which enable the derivation of reduced-part-count truss configurations from the octet truss by removing struts and nodes. These techniques are unique because their Morphological origination and they allow for the systematic generation and analysis of a large variety of structures. Methods for easily determining the part count and redundancy of infinite truss configurations are presented. Nine examples of truss configurations obtained by applying the derivation techniques are considered. These configurations are structurally stable while at the same time exhibiting significant reductions in part count. Some practical and analytical considerations, such as structural performance, regarding the example reduced-part-count truss geometries are briefly discussed

An Assessment of the Core Curriculum in the Junior High Schools of the Omaha Public Schools

The origin of the term Core, is uncertain, but programs bearing that label began to appear in 1929 and 30. The progressive movement was partially responsible for a movement to integrate and fuse courses in order to make them more meaningful and useful

Art Ecology and Planning: Strategic Concepts and Creativity within the Post Industrial Public Realm

This is a digitised version of a thesis that was deposited in the University Library.

The general focus was on transformative approaches to contemporary public art. The specific interest (and area of practice) is defined by artwork that takes an interdisciplinary approach to new forms of social creativity in the context of post-industrial environmental change. This dissertation begins with a broad literature review to understand public art and its relationship to: the public realm, ecology, nature and the environment. The intent was to understand the theory and process that inform answers to questions regarding the artists' ability to affect public policy; the ability to expand the creative act beyond singular authorship and finally the question of can we verify the impact of art? The thesis closes with two chapters describing practical work on 'Nine Mile Run' a project that developed an ecological restoration approach to post-industrial public space; also '3 Rivers 2nd Nature' which focused upon the emancipation of, and a means to advocate for post industrial nature. These projects were developed with the intention to test theory through application and value through outcome. The goal was to provide a better understand of ideas that define and enable collaborative or inter-relational approaches to transformative art practice. The intention was to make a small contribution to the theoretical framework that informs the conceptualization, experience and valuation of transformative public art practices that intend to affect the material and conceptual forms of the post-industrial public realm. It is through intellectual study and ongoing practice that the three original questions are addressed with a cautionary affirmative. Other specific findings include the following. • The ongoing tension between individual freedom and social interaction is best addressed through a moral commitment to creativity in relationship to the emancipation of people, places and things. • Visual evidence can not be the sole focal point of critical engagement with transformative practice. • Transformative practices that undertake an inter-relational methodology demand ethical, responsible and distributed outcomes
