Equilibria and oscillations of magnetised neutron stars
No full textWe investigate equilibrium configurations and oscillation spectra of neutron stars,modelled as rotating magnetised fluid bodies in Newtonian gravity. We also explorethe idea that these model neutron stars could have dynamics analogous to rigid-bodyfree precession.In axisymmetry, the equations of magnetohydrodynamics reduce to a purelytoroidal-field case and a mixed-field case (with a purely poloidal-field limit). Wesolve these equations using a nonlinear code which finds stationary rotating magnetisedstars by an iterative procedure. We find that despite the general nature ofour approach, the mixed-field configurations we produce are all dominated by theirpoloidal component. We calculate distortions induced both by magnetic fields andby rotation; our results suggest that the relationship between the magnetic energyand the induced ellipticity should be close to linear for all known neutron stars.We then investigate the oscillation spectra of neutron stars, using these stationaryconfigurations as a background on which to study perturbations. This is doneby evolving the perturbations numerically, making the Cowling approximation andspecialising to purely toroidal fields for simplicity. The results of the evolutionsshow a number of magnetically-restored Alfv´en modes. We find that in a rotatingstar pure inertial and pure Alfv´en modes are replaced by hybrid magneto-inertialmodes. We also show that magnetic fields appear to reduce the effect of the r-modeinstability.Finally, we look at precession-like dynamics in magnetised fluid stars, using bothanalytic and numerical methods. Whilst these studies are only preliminary, theyindicate deficiencies in previous research on this topic. We suggest ways in whichthe problem of magnetised-fluid precession could be better understood
Writing and the rights of reality: usurpation and potentiality in Derrida, Plato, Nietzsche, and Beckett
No full textThe thesis critically evaluates Jacques Derrida's conferral of the rights of reality on writing, focussing on his theory of an arche-text in light of the speculative nature of this theory. The theory is initially considered in the context of Derrida's elucidation of the usurpatory status of writing within the Platonic and Nietzschean texts. This consideration reveals an admission of writing's usurpatory status by both writers while at the same time demonstrating their awareness of the intrinsically speculative nature of this view, the significance of writing lying in its ability to exteriorise the radically indeterminate status of consciousness m relation to reality rather than its ability to displace consciousness or reality The analyses, therefore, not only bring the Derridean hypothesis of a repressive or phonocentric metaphysical episteme into question but also exhibit the historical and philosophical role of potentiality in relation to writing, writing's ultimate significance lying in its capacity to exteriorise our existence as a mode of potentiality. Accordingly, in the second half of the thesis the Derridean theory of writing is countered with a specifically Aristotelian theory of the text as it is exhibited in the prose of Samuel Beckett, an author whose significance lies in his close alignment with Derridean theory within contemporary criticism. It is demonstrated that this identification has obviated an awareness of the significance of potentiality within the Beckettian text, his work consequently being appraised in the previously neglected context of Aristotelian metaphysics
Samuel Huntington's clash of civilizations hypothesis: challenges from Amartya Sen and the Western South Asian post-immigrant experience
No full textSamuel Huntington ... contends that civilization identities in our modern world are fundamentally based on major divisions of cultural identity. According to Huntington, a resurgence in cultural identities is reinforcing cultural differences leading to a world characterized by culturally-based civilizational divisions, and a clash of civilization . As a counterpoint, Amartya Sen ..., a Nobel Laureate in Economics, also recognizes the pervasive nature of cultural divisions that are instigating violence and clashes but analyzes and advocates remedies to future, culturally-based clashes. In this project, I explore Huntington and Sen's ideas related to cultural transformation as they pertain to the clash of civilizations hypothesis. Their ideas are compared to three case studies derived from the existing social science literature related to Western South Asian post-immigrant experiences. I offer answers to the following questions: What are Samuel Huntington's and Amartya Sen's conceptualizations of cultural transformation? How well do these conceptualizations apply to the experience of post-immigrants? And does their ability to explain (or not explain) the post-immigrant experience reinforce or weaken the case for a clash of civilizations? In the end, I found that Sen's work best characterizes and explains the post-immigrant experience, and that this calls into doubt the validity of the clash of civilizations hypothesis.The original print copy of this thesis may be available here: http://wizard.unbc.ca/record=b136234
Tracking deep-water flow on Eirik drift over the past 160 kyr: linking deep-water changes to freshwater fluxes
No full textThis dissertation uses surface and deep ocean proxies to understand changes in North Atlantic deep-water production associated with periods of increased freshwater input throughout the Late Pleistocene and Holocene. Coring sites on Eirik Drift have long-term sedimentation rates exceeding 15 cm/kyr., allowing for paleoceanographic reconstructions on Milankovitch and millennial time scales.
The transition from glacial North Atlantic Intermediate Water (gNAIW) of marine isotope chron (MIC) 2 to North Atlantic Deep Water (NADW) during the Holocene is examined in Chapter 1. Early Holocene (9000-10,500 ka), sedimentation rates in core 21GGC (3471 m) are >100 cm/kyr., indicating gNAIW winnowed upstream glacial sediments, depositing at 21GGC. Enhanced sediment deposition persisted until ~9ka when long-term rates leveled off at 40 cm/kyr., indicating NADW density had stabilized. From 8.6 to 8.2 ka, catastrophic drainage of glacial Lake Agassiz poured freshwater into the North Atlantic disrupting deep-ocean circulation.
Chapter 2 focuses on the past 160 kyr at Site 1306 (2272 m) on the Eirik Drift where highest sedimentation rates occurred during MIC 2- 5d. Mean sortable silt (SS) and ?18O of N. pachyderma (s) are inversely related during this interval, indicating that changes in surface conditions above the Eirik Drift are propagated into the deep ocean. During the past 40 kyr., SS decreases are concomitant with instances of surface ocean freshening. These intervals correlate with Heinrich Events, suggesting that massive ice flows released
from the continents altered deep ocean circulation.
The final chapter examines deep-ocean response during Terminations 1 and 2. Higher insolation forcing across Termination 2 is postulated to promote rapid melting of continental glaciers, leaving little opportunity for continental storage of freshwater. Conversely, lower insolation across Termination 1 allowed continental ice to linger, allowing for the routing and rapid release of freshwater creating abrupt climate reversals (H1, YD and 8.2 kyr Event). Deep-ocean circulation during MIC 5e loses buoyancy in a fashion similar to the Holocene; however, maximum flow velocities are curtailed for ~7 kyr after the onset of interglacial conditions. This lag is best explained by the melting of Greenland into areas of NCW convection due to increased insolation forcing.Ph.D.Includes bibliographical references.by Samuel Straker Henderso

The 'true use of reading' : Sarah Fielding and mid eighteenth-century literary strategies.
No full textPhDThe aim of this thesis is to explore, by examining her life and
works, how Sarah Fielding (1710-68) established her identity as an author.
The definition of her role involves her notions of the functions of
writing and reading.
Sarah Fielding attempts to invite readers to form a sense of ties
by tacit understanding of her messages. As she believes that a work
of literature is produced through collaboration between the writer and
the reader, it is an important task in her view to show her attentiveness
toward reading practice. In her consideration of reading, she has two
distinct, even opposite views of her audience: on the one hand a familiar
and limited circle of readers with shared moral and cultural values and
on the other potential readers among the unknown mass of people. The
dual targets direct her to devise various strategies. She tries to
appeal to those who can endorse and appreciate her moral values as well
as her learning. Her writings and letters testify that she is sensitive
to the demands of the literary market, trying to lead the taste of readers
by inventing new forms.
The thesis opens with an overview of Sarah Fielding's career,
followed by a consideration of her critical attention to the roles of
reading. I go on to examine the narrative structures and strategies
she deploys, with a particular emphasis on her use of the epistolary
method. The following chapter deals with her attention to the reading
of the moral message tangibly embodied in her educational writing. It
is followed by an analysis of the activity which earned her a reputation
as a learned woman. Various as the forms of her works are, they invariably
reflect her attempt to balance herself between the two demands of
inventiveness and familiarity

No full textEvans Syndrome as the Initial Presentation of Systemic Lupus Erythromatosus in a Rural Kenyan Hospital: A Case Report
No full textAbstract: Evans syndrome is a rare autoimmune disorder characterized by the occurrence of autoimmune hemolytic anemia and immune thrombocytopenic purpura with or without immune neutropenia. The syndrome may be idiopathic, but in typical clinical settings, secondary causes, predominantly autoimmune diseases, may be the underlying etiology. We present a case of lupus presenting initially as Evans syndrome.
Keywords: Evans syndrome, autoimmune hemolytic anemia, immune thrombocytopenic purpura, systemic lupus erythromatosus, Coombs test.
