    x-ray photoelectron spectroscopy (ESCA) has been used to study platinum complexes, structural and bonding effects in complexes of the type (R(_3)P)(_2)PtXY have been investigated, bridging and terminal chlorines in dimeric complexes, L(_2)Pt(_2)Cl(_4), have been distinguished and a correlation found between C12p binding energies and (^35)CI n.q.r. frequencies in square-planar Pt-Cl complexes. At ambient temperature the complex (Ph(_3)P)(_2)Pt(C(_2_C1(_4)) has been found to undergo layer isomerisation to (Ph(_3)P)(_2)PtCl(CCl = CC1(_2)) . Using infrared spectroscopy, differences between surface and bulk effects have been followed and confirmed for related complexes. Isomerisation could be arrested by studying the olefin complex at -110 C. Some complexes of the methyleneamino (R(_2)C:N-) and aza-allyl/allene (R(_2)CNR(_2)) ligands with molybdenum and tungsten carbonyl derivatives have been studied by ESCA to gain further information on their possible bonding modes. A correlation has been found between the metal binding energies and the stretching frequencies of attached carbonyl groups. In order to acquire information on a Pt/Si0(_2) catalyst for eventual ESCA study, background investigations involving kinetic, deuterium addition/exchange and i.r. studies on the H(_2)-C(_2)H(_4)-Pt/Si0(_2) system have been performed. Catalyst poisoning has been investigated and eliminated, the reported occurrence of 'hydrogen spillover' has been disproved and the ethylene exchange rate found to be a sensitive probe of small, but reproducible support effects. The i.r. data obtained goes some way to resolving inconsistencies in the literature. The same catalyst has been subjected to preliminary ESCA investigation, with especial regard to the state of the metal during preparation and subsequent cleaning treatments. The available vacuum conditions were found to be unsuitable for adsorption studies

    Ages of the Pliocene-Pleistocene Alexandra and Ngatutura Volcanics, western North Island, New Zealand, and some geological implications

    Get PDF
    The Alexandra and Ngatutura Volcanics are the two southernmost of the Pliocene-Quaternary volcanic fields of western and northern North Island, New Zealand, northwest of Taupo Volcanic Zone TVZ. The Ngatutura Basalts are an alkalic basaltic field comprising monogenetic volcanoes. The Alexandra Volcanics consist of three basaltic magma series: an alkalic (Okete Volcanics), calcalkalic (Karioi, Pirongia, Kakepuku, and Te Kawa Volcanics), and a minor potassic series. Twenty new K-Arages are presented for the Alexandra Volcanics and 9 new ages for the Ngatutura Basalts. Ages of the Alexandra Volcanics range from 2.74 to 1 .60 Ma, and the ages of all three magma series overlap. Ages of the Ngatutura Basalts range from 1 .83 to 1.54 Ma. Each basaltic field has a restricted time range and there is a progressive younging in age of the basaltic fields of western North Island from the Alexandra Volcanics in the south, to Ngatutura, to South Auckland, and then to the Auckland field in the north. Neither of the Alexandra nor Ngatutura Volcanics shows any younging direction of their volcanic centres or any age pattern within their fields, and there is no systematic variation in age with rock composition. Any correlation of age with degree of erosion of volcanic cones is invalid for these basaltic fields; instead, the degree of erosion may be controlled by the lithology of the cones and possibly by the extent of preservation offered by the thick cover deposits of the Kauroa, Hamilton, and younger tephra beds. Stratigraphic relations have enabled the earliest member of the Kauroa Ash Formation to be dated at 2.3 Ma. This formation represents a series of widespread rhyolitic plinian and ignimbrite eruptions probably derived from TVZ and initiated during the Late Pliocene

    Recent editorials have had some focus on health policy and health reform and included commentary about the variability of output from public policy research institutes, based on their respective philosophical and ideological position. Recently, a group Global Access Partners (GAP) published a report entitled ‘Australia’s Health 2040: GAP Taskforce Report’. [1] This organisation is said to be an independent non-profit institute, established in 1997 and is a member of the TCG Group, described as a diverse and growing network of Australian-owned companies.

    An HI selected sample of galaxies - The HI mass function and the surface brightness distribution

    Get PDF
    Results from the Arecibo HI Strip Survey, an unbiased extragalactic HI survey, combined with optical and 21cm follow-up observations, determine the HI Mass Function and the cosmological mass density of HI at the present epoch. Both are consistent with earlier estimates, computed for the population of optically selected galaxies. This consistency occurs because, although the distribution of optical central surface brightnesses among galaxies is flat, we fail to find a population of galaxies with central surface brightnesses fainter than 24 B-mag/arcsec^2, even though there is no observational selection against them.Comment: 5 pages, including 3 encapsulated postscript figures.

    Irrational and Visionary Imagery in cante jondo and the Neo-Popular Poetry of Federico Garcia Lorca and Rafael Alberti

    IRRATIONAL AND VISIONARY IMAGERY IN CANTE JONDO AND THE NEO-POPULAR POETRY OF FEDERICO GARCIA LORCA AND RAFAEL ALBERTI BY DAVID A. BRIGGS B.A., Romance Languages and Literature, Boston University, 1964 M.A., Spanish, The University of New Mexico, Albuquerque, 2002 Ph.D., Spanish and Portuguese, The University of New Mexico, 2009 ABSTRACT Spanish poet Rafael Alberti of the Generation of 27 claimed that \u27Surrealism had been practiced in Spain since time immemorial as part of the tradition of popular song and folk poetry\u27 (Rafael Alberti qtd. in Harris 34). What is it that permits applying an early twentieth-century term, \u27Surrealism\u27 to the traditional popular song, cante jondo, and neo-popular poetry of Federico Garcia Lorca and Rafael Alberti? The answer begins with the verbal imagery of the popular song form cante jondo and the neo-popular lyric of García Lorca and Alberti as I demonstrate in this study. Considering the poetic imagery in cante jondo and Lorca\u27s and Alberti\u27s neo-popular work as irrational and visionary allows stating that \u27surrealism\u27 within the popular lyric existed in Spain long before \u27Surrealism\u27 as introduced by Guillaume Apollinaire. With theories of poetic creation from Carlos Bousoño, C.G. Jung and the writings of Robert Bly and Guillaume Apollinaire, I show that irrational and visionary imagery has indeed existed in \u27popular song and folk poetry since time immemorial\u27 in cante jondo verse and Lorca and Alberti\u27s neo-popular lyric allowing for the use of the term \u27surrealism. I explore the elements irrationality and visionary together with spontaneity and orality through the examination of imagery in various letra of cante jondo, limited to this genre of popular song because of the broadness of the category, and several poems from Lorca\u27s Mariana Pineda, Poema del Cante Jondo, Romancero Gitano, Yerma, and Llanto por Ignacio Sánchez Mejías and Marinero en tierra, Cal y Canto, EL ALBA DEL ALHELI, AND VERTE Y NO VERTE from Rafael Alberti\u27s work. My analysis demonstrates and supports Alberti\u27s claim that Surrealism has existed in popular song and folk poetry since time immemorial

    The State, War and Strategy: Australia’s Strategic Disconnect with its Wars of Choice in Iraq and the wider Persian Gulf Region, 1990–2014

    This dissertation examines the strategic significance of Australia’s deployment of elements of its military power to a series of wars of choice in the Middle East region between 1990-2014. From a Realist perspective, it establishes a series of strategic misalignments between Australian government decision and the state’s involvement in war. It demonstrates Australia displayed consistent strategic inconsistency between the nation’s strategic outlook and its approaches to war, military power, and strategy

    Risk-taking behavior of schizophrenics and normals

    Thesis (Ph.D)--Boston University.The aims of this study were: (1) to test whether hypotheses regarding the behavior of schizophrenics which had received support in level of aspiration studies would also be supported by decision theory type chance taking measures; and (2) to examine the kinds of risks toward which schizophrenics were most sensitive. Two theoretical models, decision theory and level of aspiration theory, dealing with decision making in situations involving the threat of failure, were shown to be basically similar in their formulation; they differed, however, in regard to the independence of probability and reward, and the degree of the individual's control over the outcome and the motive of achievement. "Risk," which was considered to be the objective equivalent of the clinical concept "threat of failure," was defined operationally as the negative term of the expected value model (i.e., as the product of the probability of loss and the amount of possible loss).
