We read a novel one sentence at a time. The first scale of attention for even the longest novel is the play of forces within the thousands of individual sentences. This project aims to rescale the analysis of novelistic form, elucidating this play of forces: how do they shape attention, and how do structures of attention give rise to aesthetic experience? We recognize the importance of form in music and architecture in part because there is no referential content to distract us. When it comes to the realist novel, however, its rich referential field easily obscures the dynamics of experience created by form. This study seeks to elucidate those dynamics. Chapter One analyzes Austen’s long interval of tension. Austen’s capacious sentence stretches attention over an entire descriptive event, producing drama and crises even when events in the fictional world are characterized by equilibrium and serenity. With the syntax of the sentence unresolved, attention cannot rest. An achieved description thus has perceptual corollaries in temporal commitment, and in attention that is divided between the immediate claims of elaboration and the prospect of closure. In Dickens, microstructures of just one to three sentences elicit the sudden apercu. Like metaphor, the apercu emerges through our recognition of a meaningful relationship between actions, facts, and utterances. Dickens presents only the raw materials of discovery (say, by juxtaposing a character’s mutually contradictory statements), leaving to us the second-order activity of recognition (her disingenuousness). Chapter Three examines how Hardy employs linguistic analogues to represent the essential structure of perceptual experience. Chapter Four, on late James, shows how shifts in attention on two scales produce two distinct experiences. Shifts to the periphery of a scene act as a temporal ballast, adding weight to the perceived dimensions of the passage. Shifts within the sentence elicit intense perceptual involvement, even when that absorption exceeds what is warranted by the semantic plane. The essence of the novel’s referenced world can be preserved in memory, but linguistic form resists memory; it is immediate and ephemeral. During the act of reading, it is one of the novel’s greatest pleasures.

I investigate aspects of fleet dynamics in a mobile gear, groundfish fishery, on the Scotian Shelf; an area subject to a seasonal area closure. Firstly, the direct impacts of the closure on the redistribution of fishing effort and the resultant catch rates of those “fishing the line” (FTL) were examined. Effort was found to concentrate within 30km of the closure boundary. Two areas of potential FTL strategy were identified, which produced variable catch rate trends. East of the closure, areas of highest catch rate corresponded to areas of greatest effort, while to the west, catch rate was often equalized throughout the region, analogous to the ideal free distribution (IFD). Secondly, two effort distributional models were compared: an IFD-based isodar model and a discrete choice model. The isodar was determined to be the preferred model because of both its consistently superior predictive performance and its greater simplicity.

The maximum entropy moment closure for the two-moment approximation of the radiative transfer equation is presented. The resulting moment equations, known as the M1 model, are solved using a finite-volume method with adaptive mesh refinement (AMR) and two Riemann-solver based flux function solvers: a Roe-type and a Harten-Lax van Leer (HLL) solver. Three different boundary schemes are also presented and discussed. When compared to the discrete ordinates method (DOM) in several representative one- and two-dimensional radiation transport problems, the results indicate that while the M1 model cannot accurately resolve multi-directional radiation transport occurring in low-absorption media, it does provide reasonably accurate solutions, both qualitatively and quantitatively, when compared to the DOM predictions in most of the test cases involving either absorbing-emitting or scattering media. The results also show that the M1 model is computationally less expensive than DOM for more realistic radiation transport problems involving scattering and complex geometries.

This thesis describes the implementation of the conditional moment closure (CMC) combustion model in a numerical scheme and its application to the modelling of enclosure fires. Prediction of carbon monoxide (CO) in the upper smoke layer of enclosure fires is of primary interest because it is a common cause of death. The CO concentration cannot be easily predicted by empirical means, so a method is needed which models the chemistry of a quenched, turbulent fire plume and subsequent mixing within an enclosed space. CMC is a turbulent combustion model which has been researched for over a decade. It has provided predictions of major and minor species in jet diffusion flames. The extension to enclosure fires is a new application for which the flow is complex and temperatures are well below adiabatic conditions. Advances are made in the numerical implementation of CMC. The governing combustion equations are cast in a conserved, finite volume formulation for which boundary conditions are uniquely defined. Computational efficiency is improved through two criteria which allow the reduction in the size of the computational domain without any loss of accuracy. Modelling results are compared to experimental data for natural gas fires burning under a hood. Comparison is made in the recirculating, post-flame region of the flow where temperatures are low and reactions are quenched. Due to the spatial flux terms contained in the governing equations, CMC is able to model the situation where chemical species are produced in the high temperature fire-plume and then transported to non-reacting regions. Predictions of CO and other species are in reasonable agreement with the experimental data over a range of lean and rich hood-fire conditions. Sensitivity of results to chemistry, temperature and modelling closures is inves- tigated. Species predictions are shown to be quite different for the two detailed chemical mechanisms used. Temperature conditions within the hood effect the for- mation of species in the plume prior to quenching and subsequently species predic- tions in the post-flame region are also effected. Clipped Gaussian and ß-function probability density functions (PDFs) are used for the stochastic mixture fraction. Species predictions in the plume are sensitive to the form of the PDF but in the post-flame region, where the ß-function approaches a Gaussian form, predictions are relatively insensitive. Two models are used for the conditional scalar dissipation: a uniform model, where the conditional quantity is set equal to the unconditional scalar dissipation across all mixture fraction space; and a model which is consistent with the PDF transport equation. In the plume, predictions of minor species are sensitive to the modelling used, but in the recirculating, post-flame region species are not significantly effected.

Many philosophers approach the free will question seeking a foundation for systems of ethics or a justification for societal practices of praise and blame. ... Rather, I address the metaphysical question of how to accommodate free will within the natural world. I conclude that the natural world is not identical with the physical world and that it must contain entities or influences that are not physical in any current sense of that word. / Mode of access: World Wide Web. / x, 228 p

In this paper, we show that a pointwise λ -symmetric λ -isotonic λ -closure function is uniquely determined by the pairs of sets it separates. We then show that when the λ -closure function of the domain is λ -isotonic and the λ -closure function of the codomain is λ -isotonic and pointwise- λ -symmetric, functions which separate only those pairs of sets which are already separated are λ -continuous.
