    We consider a model of noncommutative gravity that is based on a spacetime with broken local SO(2,3) symmetry. We show that the torsion-free version of this model is contained within the framework of the Lorentz-violating Standard-Model Extension. We analyze in detail the relation between the torsion-free, quadratic limits of the broken SO(2,3) model and the Standard-Model Extension. As part of the analysis,we construct the relevant geometric quantities to quadratic order in the metric perturbation around a flat background.Comment: 10 pages, accepted in Symmetr

    Thesis (M.B.A.)--Boston UniversityFrom that eventful day in 1750 When electrical current was first discovered and through the succeeding years Where such famous inventions as the electric light, the telephone, and generation of alternating current, were brought into being, to this present age of electronic development, the electro~echanical aids available to industrial management have mounted in number. Many of the basic inventions of the Nineteenth Century, although they have been improved steadily, are accepted as commonplace. Take for instance, the telephone or the electric light, little thought is given to their importance in everyday life. It takes a sudden power failure to firmly indicate our dilemma. In the modern factory loss of power can result in stoppage of machinery, loss of time and costly damage. Many of the newer windowless plants depend on artificial light for their existence; thus, loss of light by power failure can cause accidents in addition to the foregoing results

    Merged with duplicate record 10026.1/669 on 27.02.2017 by CS (TIS)This thesis is the first sustained critical analysis of the poetry of Ronald Duncan (1914-1982). As this is the first study of Duncan's poetry, a substantial part is exegesis and follows a chronological pattern. Duncan was a man of letters who wrote poetry, plays, librettos, songs, short stories, journals, autobiographies, biographies and novels. He was strongly influenced by T. S. Eliot and Ezra Pound. Their poetics and personal advice enabled Duncan to produce a series of publications that pursued some basic modernist tenets, such as an adherence to a European poetic tradition and the belief that poetry could induce cultural renewal, via an overtly subjectivised perspective. A chapter of this thesis has been allocated for each of Duncan's poetry publications. The introduction explores the personal and ideological importance of Pound and Eliot for Duncan; Pound's input into Duncan's magazine Townsman: and how Eliot, as Duncan's publisher, was able to offer a significant platform for his poetry. It also examines the position of the writer in relation to his writing, to show how the subjectivity of modernist authors compared with Duncan's belief that authorial presence was an essential part of any genuine poetic endeavour. Duncan's poetic career spanned almost forty years, from 1939 to 1977. His first publication, Postcards to Pulcinella (c1939), exemplifies his early experimentation with form. His next, and first Faber publication, The Mongrel (1950), is notable for its diversity of form and theme, and develops a greater awareness of European poetic diversity than is present in Postcards to Pulcinella. The Solitudes (1960) introduces a reworking of love poem sequences, which is developed in Unpopular Poems (1969) and For The Few (1977), and concentrates increasingly on lost love and personal grief. Between Unpopular Poems and For the Few Duncan published the five parts of his epic narrative poem Man (1970-4). This major work charts the history of the universe and human development, and blends poetic with scientific discourse. Man exemplifies, above all else, Duncan's on-going belief that all things exist only in his conscious understanding. The relationship between Duncan, the writing process and the resultant poetry, is a recurrent theme throughout the thesis. By drawing a distinction between author (writing subject) and the written representation of that author in the poetry (written subject) it explores the relationship between Duncan's own consciousness, the world it perceives, and the linguistic structures he uses in communicating their conjunction. Each of Duncan's poetry publications develops themes of love, sex, nature, human nature, Christianity and subjective isolation. Employing a variety of verse forms and tropes these themes are teased out book by book, but conclude with his belief that conscious expansion and cultural development through poetry was a futile, but nevertheless necessary, endeavour.The Ronald Duncan Trus
