Claude McKay and the transnational novel

This thesis considers the three works of fiction of the Jamaican author Claude McKay (1889-1948) as a coherent transnational trilogy which dramatises the semi-autobiographical complexities of diasporic exile and return in the period of the 1920s and 1930s. Chapter One explores McKay’s urban North American novel, Home to Harlem (1928). I suggest that we need to ‘reworld’ conceptions of McKay’s writing in order to release him from his canonical confinement in the Harlem Renaissance. Querying the problematics of the city space, of sexuality and of race as they emerge in the novel, this chapter considers McKay’s percipient understanding of the need to reconfigure diasporic identity beyond the limits set by American nationalism. Chapter Two engages with McKay’s novel of portside Marseilles, Banjo (1929), and considers the homosocial interactions of the vagabond collective. A comparison of North America and France as supposed exemplars of individual liberty highlights the unsuitability of nationalistic prerogatives to an internally diverse black diaspora. Paul Gilroy’s Black Atlantic construct provides a suggestive space in which to re-imagine the possibilities of affiliation in the port. The latter section of the chapter examines McKay’s particular influence on, and relationship, to the Négritude movement and Pan-African philosophies. Chapter Three focuses on McKay’s third novel, Banana Bottom (1933). I suggest here that the three novels comprise a coherent New World Trilogy comparable to Edward (Kamau) Brathwaite’s trilogy, The Arrivants. This chapter considers both the Caribbean and the transnational dimensions to McKay’s work.

An investigation of techniques for the measurement and interpretation of cosmic ray isotopic abundances

An instrument, the Caltech High Energy Isotope Spectrometer Telescope (HEIST), has been developed to measure isotopic abundances of cosmic ray nuclei in the charge range 3 ≤ Z ≤ 28 and the energy range between 30 and 800 MeV/nuc by employing an energy loss -- residual energy technique. Measurements of particle trajectories and energy losses are made using a multiwire proportional counter hodoscope and a stack of CsI(TI) crystal scintillators, respectively. A detailed analysis has been made of the mass resolution capabilities of this instrument.

Landau fluctuations set a fundamental limit on the attainable mass resolution, which for this instrument ranges between ~.07 AMU for z~3 and ~.2 AMU for z~2b. Contributions to the mass resolution due to uncertainties in measuring the path-length and energy losses of the detected particles are shown to degrade the overall mass resolution to between ~.1 AMU (z~3) and ~.3 AMU (z~2b).

A formalism, based on the leaky box model of cosmic ray propagation, is developed for obtaining isotopic abundance ratios at the cosmic ray sources from abundances measured in local interstellar space for elements having three or more stable isotopes, one of which is believed to be absent at the cosmic ray sources. This purely secondary isotope is used as a tracer of secondary production during propagation. This technique is illustrated for the isotopes of the elements O, Ne, S, Ar and Ca.

The uncertainties in the derived source ratios due to errors in fragmentation and total inelastic cross sections, in observed spectral shapes, and in measured abundances are evaluated. It is shown that the dominant sources of uncertainty are uncorrelated errors in the fragmentation cross sections and statistical uncertainties in measuring local interstellar abundances.

These results are applied to estimate the extent to which uncertainties must be reduced in order to distinguish between cosmic ray production in a solar-like environment and in various environments with greater neutron enrichments.

Stylistics, criticism and mythrepresentation again: squaring the circle with Ray Mackay's subjective solution for all problems

This article is a response to an article by Ray Mackay (1996) which constitutes an attack on stylistic analysis in general, and the writings of the above authors and Ron Carter in particular. Mackay's article (in Language and Communication) accuses stylistics of 'scientificness' and claims that its attempt to provide objective analyses of literary texts is futile.1 We suggest that Mackay has misrepresented what stylisticians have said about objectivity, and that his understanding of objectivity, science and the nature of text-interpretative argument is seriously flawed.

Inspiration and mimesis in Plato's criticism of poetry

Plato criticizes poetry in several of his dialogues, beginning with Apology, his first work, and ending with Laws, his last. In these dialogues, his criticism of poetry can be divided into two streams: poetry is criticized for either being divinely inspired, or because it is mimetic or imitative of reality. However, of the dialogues which criticize poetry in these ways, it is not until Laws that Plato mentions both inspiration and mimesis together, and then it is only in a few sentences. Furthermore, nowhere in the dialogues does Plato discuss their relationship. This situation has a parallel in the secondary literature. While much work has been done on inspiration or mimesis in Plato’s criticism of poetry, very little work exists which discusses the connection between them. This study examines Plato’s treatment - in the six relevant dialogues - of these two poetic elements, inspiration and mimesis, and shows that a relationship exists between them. Both can be seen to relate to two important Socratic-Platonic concerns: the care of the soul and the welfare of the state. These concerns represent a synthesis of Socratic moral philosophy with Platonic political beliefs. In the ‘inspiration’ dialogues, Ion, Apology, Meno, Phaedrus and Laws, poetic inspiration can affect the Socratic exhortation which considers the care of the individual soul. Further, as we are told in Apology, Crito and Gorgias, it is the good man, the virtuous man - the one who cares for his soul - who also cares for the welfare of the state. Therefore, in its effect on the individual soul, poetic inspiration can also indirectly affect the state. In the ‘mimesis’ dialogues, Republic and Laws, this same exhortation, on the care of the soul, is posed, but it is has now been rendered into a more Platonic form - as either the principle of specialization - the ‘one man, one job’ creed of Republic, which advances the harmony between the three elements of the soul, or as the concord between reason and emotion in Laws. While in Republic, mimesis can damage the tripartite soul's delicate balance, in Laws, mimesis in poetry is used to promote the concord. Further, in both these dialogues, poetic mimesis can affect the welfare of the state. In Republic, Socrates notes that states arc but a product of the individuals of which they are composed Therefore, by affecting the harmony of the individual soul, mimesis can then undermine the harmony of the state, and an imperfect political system, such as a timarchy, an oligarchy, a democracy, or a tyranny, can result. However, in Laws, when it is harnessed by the philosophical lawgivers, mimesis can assist in the concord between the rulers and the ruled, thus serving the welfare of the state. Inspiration and mimesis can thus be seen to be related in their effect on the education of both the individual, in the care of the soul, and the state, in its welfare. Plato's criticism of poetry, therefore, which is centred on these two features, addresses common Platonic concerns: in education, politics, ethics, epistemology and psychology.

Challenges in the quantification and interpretation of spike-LFP relationships

Brain signals often show fluctuations in particular frequency bands, which are highly conserved across species and are associated with specific behavioural states. Such rhythmic patterns can be captured in the local field potential (LFP), which is obtained by low-pass filtering the extracellular signal recorded from microelectrodes. However, LFP also captures other neural processes that are associated with spikes, such as synaptic events preceding a spike, low-frequency component of the action potential (spike bleed-through'') and spike afterhyperpolarization, which pose difficulties in the estimation of the amplitude and phase of the rhythm with respect to spikes. Here we discuss these issues and different techniques that have been used to dissociate the rhythm from other neural events in the LFP.

2-D and 3-D processing and interpretation of multi-fold ground penetrating radar data:a case history from an archaeological site

A 2.5-D and 3-D multi-fold GPR survey was carried out in the Archaeological Park of Aquileia (northern Italy). The primary objective of the study was the identification of targets of potential archaeological interest in an area designated by local archaeological authorities. The second geophysical objective was to test 2-D and 3-D multi-fold methods and to study localised targets of unknown shape and dimensions in hostile soil conditions. Several portions of the acquisition grid were processed in common offset (CO), common shot (CSG) and common mid point (CMP) geometry. An 8×8 m area was studied with orthogonal CMPs thus achieving a 3-D subsurface coverage with azimuthal range limited to two normal components. Coherent noise components were identified in the pre-stack domain and removed by means of FK filtering of CMP records. Stack velocities were obtained from conventional velocity analysis and azimuthal velocity analysis of 3-D pre-stack gathers. Two major discontinuities were identified in the area of study. The deeper one most probably coincides with the paleosol at the base of the layer associated with activities of man in the area in the last 2500 years. This interpretation is in agreement with the results obtained from nearby cores and excavations. The shallow discontinuity is observed in a part of the investigated area and it shows local interruptions with a linear distribution on the grid. Such interruptions may correspond to buried targets of archaeological interest. The prominent enhancement of the subsurface images obtained by means of multi-fold techniques, compared with the relatively poor quality of the conventional single-fold georadar sections, indicates that multi-fold methods are well suited for the application to high resolution studies in archaeology.
