Introduction: preliminary reflections on the legacy of Pierre Bourdieu
No full textBook synopsis: Pierre Bourdieu is widely regarded as one of the most influential sociologists of his generation, and yet the reception of his work in different cultural contexts and academic disciplines has been varied and uneven. This volume maps out the legacy of Pierre Bourdieu in contemporary social and political thought from the standpoint of classical European sociology and from the broader perspective of transatlantic social science. It brings together contributions from prominent scholars in the field, providing a range of perspectives on the continuing relevance of Bourdieu’s oeuvre to substantive problems in social and political analysis

MarChemSpec (Marine Chemical Speciation Model)
No full text<p><strong>The MarChemSpec Models</strong></p>
<p>These programs (for Windows, Linux, and macOS 'Apple silicon') implement the models described in the three papers, and one manuscript in preparation, listed further below. The models determine the equilibrium chemical speciation for each input natural water composition and temperature. Outputs are the equilibrium composition of the solution on both an amount content and molality basis, all activity coefficients, and other properties as noted below.</p>
<p>The various zip and tar archives contain the executable programs, and functions that can be called by MATLAB or Python.The \docs directory of each archive contains manuals with instructions and examples.</p>
<p>See <a href="http://marchemspec.org">marchemspec.org</a> for details of our project, and email Simon Clegg ([email protected]) or David Turner ([email protected]) if you have questions.</p>
<p><strong>1. Models Available as Standalone Programs</strong></p>
<p><em><strong>Sea</strong></em> - The model of solutions containing the ions of seawater electrolyte (paper 3), including carbonate, borate, and fluoride acid-base equilibria. Outputs include the seawater state parameters alkalinity, <em>p</em>CO2 and <em>f</em>CO2, total and free pH; the stoichiometric acid-base equilibrium constants of carbonate, borate and fluoride; and the stoichiometric concentration product of calcium and carbonate. Estimates of the uncertainties of the calculated quantities are provided.</p>
<p><em><strong>Delta</strong></em> - This is the same chemical model as 'sea', but calculates the changes in the outputs listed above caused by a change in the natural water composition (typically from seawater to something different). Estimates of the uncertainties of these calculated changes are provided.</p>
<p><em><strong>Trace</strong></em> - The model of solutions containing the ions of seawater electrolyte, and inorganic complexation of the GEOTRACES metals Al, Cd, Co, Cu(II), Fe(II), Fe(III), Mn, Ni, Pb and Zn (paper 4). Outputs are the concentrations (as amount contents and molalities) of all species, and the free and complexed fractions of each of the trace metals. There are no estimates of uncertainties.</p>
<p><strong>2. MATLAB and Python Functions</strong></p>
<p>These functions, available for Windows and for Linux, allow all three models above to be called directly within MATLAB and Python environments. In addition, the functions include the model of artificial seawater (like seawater electrolyte, but without Sr or carbonate, borate, and fluoride species); and also the draft model of Tris buffer in artificial seawater (papers 1 and 2).</p>

<p>1.00: initial release available only at marchemspec.org (from early June 2023), and used for tutorials at a meeting at Woods Hole Oceanographic Institution during that month. </p>
<p>1.01: an error in the calculation of activity coefficients of Cu(II) in the 'trace' model at temperatures other than 25 oC has been corrected. Minor improvements were made to the manuals, and in the use of '/' and '\' in path arguments in the Python function. Known issues in this version: (a) an error message related to file handling is incorrect (this should rarely be encountered), (b) there is an error of approx. -0.4% in the calculation of the CO2(g) fugacity coefficient; (c) the speciation calculation fails for some unusual compositions.</p>

Late-orogenic, mantle-derived, bimodal magmatism in the southern Adelaide Foldbelt, South Australia / by Simon P. Turner.
Full text linkCopies of author's previously published articles inserted.Bibliography : leaves 179-196.v, 196, [43] leaves : ill. (some col.), maps ; 30 cm.Late-orogenic magmas are common to many foldbelts, suggesting a causal link between this thermal pulse and the cessation of deformation. An investigation of such a late-orgenic magnetic suite is made in the southern Adelaide Foldbelt. The suite is biomodal with mafic dykes and plutons accompanied by high-silica granites and rhyolites. It is argued that these mafic and felsic intrusives are both thermally and compositionally related.Thesis (Ph.D.)--University of Adelaide, Dept. of Geology and Geophysics, 199
