The reduction of metaphysics and the play of violence in the poetry of Wallace Stevens
No full textPhDThe thesis demonstrates how Wallace Stevens' poetry utilises pre-Socratic philosophy in overcoming post-Kantian dislocation from the 'thing-in-itself'. I initially consider Stevens’ poetry in terms of Hans-Georg Gadamer's ontological conception of the 'play' of art, an interactive existence overlooked by Kant. Through the ‘play’ of Stevens’ poems the reading audience are implicated in their reduction to being. The origin of this conception leads Gadamer back to Parmenides who Stevens had read. I argue that Stevens’ poetry ‘plays’ its audience into an ontological ground in an effort to show that his ‘reduction of metaphysics’ is not dry philosophical imposition, but is enacted by our encounter with the poems themselves. Through an analysis of how the language and form of Stevens’ poems attempt to reduce mind and world to concepts that parallel Parmenides’ poetic sense of being, and Heraclitus’ notion of becoming, the thesis uncovers the ground in which Stevens attempts a reconnection with the ‘thing-in-itself’. It is through the experience of reconnecting to an ontological centre, which his poetry presents as the human project, that Stevens’ poetry also presents itself as a means of replacing religion.From here we turn to Emmanuel Levinas and Jacques Derrida for an exposition of how such a reduction reduces the ‘Other’ to ‘otherness’ and their worry that this reduction legitimates violence within the thought of Martin Heidegger and Parmenides. From this I make a case for how such reductions are connected to what I refer to as 'the play of violence' in Stevens' poetry, and to refer this violence back to the mythology Stevens' poetry shares with certain pre-Socratics and with Greek tragedy. This shows how such mythic rhythms are apparent within the work of Friedrich Nietzsche, Heidegger and Gadamer, and how these rhythms release a poetic understanding of the violence of a ‘reduction of metaphysics’

At limits of life: multidisciplinary insights reveal environmental constraints on biotic diversity in continental Antarctica
No full textData source: Supporting information, http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0044578#s5Multitrophic communities that maintain the functionality of the extreme Antarctic terrestrial ecosystems, while the simplest of any natural community, are still challenging our knowledge about the limits to life on earth. In this study, we describe and interpret the linkage between the diversity of different trophic level communities to the geological morphology and soil geochemistry in the remote Transantarctic Mountains (Darwin Mountains, 80uS). We examined the distribution and diversity of biota (bacteria, cyanobacteria, lichens, algae, invertebrates) with respect to elevation, age of glacial drift sheets, and soil physicochemistry. Results showed an abiotic spatial gradient with respect to the diversity of the organisms across different trophic levels. More complex communities, in terms of trophic level diversity, were related to the weakly developed younger drifts (Hatherton and Britannia) with higher soil C/N ratio and lower total soluble salts content (thus lower conductivity). Our results indicate that an increase of ion concentration from younger to older drift regions drives a succession of complex to more simple communities, in terms of number of trophic levels and diversity within each group of organisms analysed. This study revealed that integrating diversity across multi-trophic levels of biotic communities with abiotic spatial heterogeneity and geological history is fundamental to understand environmental constraints influencing biological distribution in Antarctic soil ecosystems.Catarina Magalhães, Mark I.

Wavenumber-frequency spectra in the logarithmic layer of wall turbulence
No full textWe study space-time correlations of wall-bounded turbulence in terms of wavenumber-frequency spectra of the streamwise velocity component. The spectra are obtained from Large Eddy Simulations (LES), which provide a full space-time record of the flow. We find that the frequency distributions exhibit a Doppler shift, which is a consequence of mean flow advection, as well as a considerable Doppler broadening, consistent with the Kraichnan-Tennekes random sweeping hypothesis. For wall-bounded turbulence, both of these effects vary with the wall distance and are closely related to the logarithmic behavior of the mean velocity profile and the velocity fluctuation profiles. We incorporate these observations into a simple analytical model for the wavenumber-frequency spectrum based on an advection equation featuring advection of the small-scale velocity fluctuations with a mean and a large-scale random-sweeping velocity. The model is found to be in very good agreement with the LES data. Potential applications of the model spectrum, e.g., to quantify the spatio-temporal structure of fluctuations in wind energy conversion, will be discussed

Optical orientation in self assembled quantum dots
No full textWe examined Zeeman splitting in a series of ln_xGa_(_1_-_x_)As/GaAs self assembled quantum dots (SAQD's) with different pump polarisations. All these measurements were made in very low external magnetic fields where direct determination of the Zeeman splitting energy is impossible due to its small value in comparison to the photoluminescence linewidths. The use of a technique developed by M. J. Snelling allowed us to obtain the Zeeman splitting and hence the excitonic g-factors indirectly. We observed a linear low field splitting, becoming increasingly non-linear at higher fields. We attribute this non-linearity to field induced level mixing. It is believed these are the first low field measurements in these structures. A number of apparent nuclear effects in the Zeeman splitting measurements led us onto the examination of nuclear effects in these structures. The transverse and oblique Hanie effects then allowed us to obtain the sign of the electronic g-factors in two of our samples, for one sample, a (311) grown In_0_._5Ga_0_._5As/GaAs SAQD sample, we were able to ascertain the spin relaxation time, the maximum value of the nuclear field, and provide evidence of the existence of nuclear spin freezing in at least one of our samples. We have then used a novel technique investigated by D. J. Guerrier, to examine optically detected nuclear magnetic resonance in our samples. We believe this is the first such study on these structures. We could not ascertain the dipolar indium resonance signal, even though all other isotopes were seen. We have therefore suggested a number of possible mechanisms that may be responsible for the lack of an indium resonance signal.

Inescapable choice: Wallace Stevens's new Romanticism and English romantic poetry
No full textThe aim of this thesis is to investigate how Stevens creates a new Romanticism. It argues that Stevens demonstrates a double view of Romanticism as having positive and negative aspects and it relates discussion of this double view to the development of his poetry and theories of poetry. Stevens shares with the Romantics the belief that through the power of imagination the problem of dualism - especially the split between art and existential reality - can be solved. Prom Stevens's perspective, thinking about what should be respected and what should be corrected in Romanticism provides grounds for the creation of his own new Romanticism. In chapters one and two, by examining the conflict between imagination and reality in the works of Coleridge, Wordsworth, Shelley and Keats, I explore the intertextual relations between Stevens and the Romantics from a perspective informed by the implications of Stevens's work and thought. In chapters three and four, focusing on Stevens's treatment of the relation between imagination and reality, I examine the nuanced differences between his work and that of the Romantics. Chapter five provides a prologue to 'Notes toward a Supreme Fiction', the culmination of Stevens's concern with imagination and reality. In the final chapter I examine how Stevens's new Romanticism, especially its emphasis on the imagination's activity, is concretised in 'Notes toward a Supreme Fiction'. I also explore how the later development of his sense of reality affects his poetic creativity. By examining the influence of the Romantics on Stevens and his response to them, the nature of his poetry can be more accurately understood. Throughout the thesis, I engage, as appropriate, with the work of many critics who have written on Stevens. It is my hope that my own approach gives a folly considered and detailed account of a topic often addressed more briefly by other commentators
