δ Orionis: Further temporal variability and evidence for small-scale structure in the interstellar medium
No full textWe report here the detection of both spatial and temporal variations in interstellar absorption in the line of sight to δ Orionis. First, we present new high-resolution (R≈110 000) observations of the interstellar D lines of Na i towards both δ Ori A and C. Comparison of these spectra highlights variations in absorption between the two stars, indicative of small-scale spatial structure in the interstellar medium in this direction over distances of less than ≈15 000 au (the projected separation of the two stars). Components with the largest Na i column densities and lowest velocity dispersions are, in general, found to be subject to the greatest differences; in fact the narrowest component detected is only observed in one of the sightlines. This effect has also been reported by Meyer & Blades. Secondly, we present new ultra-high-resolution (R≈900 000) Na i D1 observations and high-resolution (R≈110 000) Ca ii H & K observations of δ Ori A which, through ultra-high-resolution work conducted between 1994 and 2000, has been shown to exhibit a time-variable interstellar Na i absorption component. These new observations, while revealing the further reduction in intensity of the time-variable Na i absorption, indicate constant Ca ii absorption over the same period. This results in a dramatic reduction in the Na°/Ca+ abundance ratio, perhaps indicating the line of sight to be gradually probing a less-dense outer region of an absorbing filament

Review: David Howarth (2000). Discourse
No full textHOWARTH's book is an accessible, readable and concise overview of theories of and approaches to discourse in the human and social sciences, focusing upon LACLAU and MOUFFE's discourse theory approach. The roots of this approach are described in structuralist and post-structuralist theories including the work of SAUSSURE, LEVI-STRAUSS, DERRIDA and FOUCAULT, as well as the MARXism of ALTHUSSER, GRAMSCI and PECHEUX. The book is mostly even-handed and the author takes great care to make his material accessible. However, critical realist alternatives to poststructuralism receive little attention and issues of agency and subjectivity remain problematic. These issues are part of the wider debate between realism and relativism, the intransigence of which is somewhat downplayed in this book. Nevertheless, HOWARTH has produced a valuable resource which should be welcomed by teachers and students in this field.HOWARTH's book is an accessible, readable and concise overview of theories of and approaches to discourse in the human and social sciences, focusing upon LACLAU and MOUFFE's discourse theory approach.

Las raíces de este enfoque son descritas en las teorías estructuralistas y post estructuralistas, incluyendo el trabajo de SAUSSURE, LEVI-STRAUSS, DERRIDA y FOUCAULT, así como el marxismo de ALTHUSSER, GRAMSCI y PECHEUX. El libro es en su mayor parte imparcial y el autor se esfuerza en hacer accesible el material. Sin embargo, las alternativas crítica realistas al post estructuralismo reciben poca atención y asuntos como la gestión humana y la subjetividad permanecen problemáticos. Estas cuestiones son parte del debate más amplio entre realismo y relativismo, intransigencia del cual es de alguna manera presentada en este libro.
