abstract:
Social fears gain in prominence among higher primates, including humans, where threats associated with other conspecifics become more common. Social fearfulness is expressed on a continuum, ranging from shyness to a diagnosable psychiatric disorder. Despite the wide prevalence and considerable distress associated with social anxiety, our understanding of its neural and cognitive correlates remains in its infancy and remains an imperative for future translational research. The current dissertation examined social anxiety by utilizing multiple experimental approaches and employing a broad range of measures involving neural, cognitive, behavioural and clinical assessments.

Chapters 2 to 4 relied on nonclinical samples of adults selected for social anxiety from a large adult population. Chapters 2 and 3 employed event-related brain potentials to index distinct aspects of perceptual and cognitive processing in tasks that manipulated novelty under socio-emotional and affectively neutral contexts. The aim was to provide a fine-grained characterization of the information processing stages that are biased by social anxiety. Chapter 4 measured reaction times in a selective attention task that independently varied the temporal and energetic aspects of affective stimulus delivery to provide convergent evidence into how affective processing is perturbed by social anxiety. Chapter 5 employed a novel method of quantifying continuous EEG to examine large-scale brain activity during rest and symptom provocation in patients diagnosed with social anxiety disorder. The aim was to examine, for the first time, whether there are treatment-related changes in a measure that putatively indexes communication across different (cortical and subcortical) neuronal systems.

Findings suggest that social anxiety is associated with a sensitization of (bottom-up) systems reacting to social threat and that these biases appear during the early, relatively automatic stages of information processing. Some of these systems may be susceptible to evidence-based psychological treatments that are correlated with changes in brain activity detectable in EEG patterns.

abstract: This dissertation examines the thought of Jean-Luc Marion in light of his treatment of divine revelation and in connection to the hermeneutic phenomenology of Paul Ricoeur. It argues, first, that Marion’s thought bears within itself significant ambiguities that are determined by the legacies of the key concepts which organize his work: ‘givenness’ (donation) and saturation. Secondly, it also argues that even if a way can be found to resolve these ambiguities the resultant proposal does not meet the criticism raised by Paul Ricoeur in reference to phenomenologies of religion that remain determined by a ‘Husserlian idealism.’ As a result, the dissertation offers a study of Ricoeur’s hermeneutics of revelation in an effort to displace Marion’s account and offer an alternative proposal. Specifically, it treats the connection of Ricoeur’s proposed transformation of phenomenology through hermeneutics, the idea of a hermeneutics of testimony that is generated as a result of that transformation, and Ricoeur’s notion of revelation as being articulated in reference to the ‘world of the text.’ By focusing on the notion of ‘anteriority’ throughout the analysis, the dissertation argues that not only does Marion’s work remain limited by its formal commitments to pure apparition, but it fails to access the sort of radical anteriority that it seeks. This is so because it remains tied to a philosophy of consciousness which is blocked from accessing the pre-reflective level of belonging that is made accessible by Ricoeur’s hermeneutic phenomenology. By making this argument, the dissertation provides a critical analysis of Marion’s work from the perspective of divine revelation and, furthermore, brings that work into conversation with Paul Ricoeur. This important engagement between Ricoeur and Marion has not been adequately addressed in the current secondary literature and this dissertation fills that gap.

abstract:
This thesis is an analysis of the use of symbols and imagery in A Jest of God and The Stone Angel. It finds, simply stated, that there is a basic stress upon duality employed by Mrs. Laurence in those novels which gives her writing a good portion of the dramatic tension of real life.

The introduction attempts briefly to show cause for Mrs. Laurence's doubleness of vision with reference to her African experience and the basic, but colourful, conflicts between the Europeans and the Africans, and between Tribal Africa and Nationalistic Africa which she witnessed as a budding writer. In the first chapter, which deals with The Stone Angel, this dualism is shown to be generated by the two Hagars (i.e. the od lady and the flashbacks of her self) and St. Paul's concept of two covenants: one old, one new. The importance of this second concept, which incorporates the contradicting tenets of Old Testament pride and fear, and New Testament freedom and hope, is reflected in the major role given to biblical imagery. For that reason the focus of my study of The Stone Angel concentrates upon those biblical symbols and images. This biblical examination is followed up in the chapter on A Jest of God, but, as the primary conflict represented in that novel's symbolism and imagery deals with Rachel, the child, and Rachel, the emerging mother, and, as that primary dramatic spring is rendered in a manner which fits Carl G. Jung's description of neurotic dissociation, I have correspondingly shifted in that chapter to a more psychological emphasis in my analysis.

abstract: This thesis is concerned with some aspects of Ann Radcliffe's development as a writer. Most of it deals with her as a writer of Gothic novels: her groups of Gothic and Romantic characters, her treatment of suspense, and her use of the Gothic castle. The chapter on landscape and background treats an aspect of her work which is not exclusively Gothic, but which contributes to the Gothic atmosphere, and which is sufficiently characteristic of her to warrant separate consideration. Some attention is given to sources and influences, and an attempt is made to evaluate her various techniques.

abstract: This thesis examines the allegorical aspects of Fielding's novels, and particularly of Tom Jones. According to the view presented here, Tom Jones is a psychomachy a form of allegory in Which personified psychological .entities engage in a mental struggle. Squire Allworthy is an allegorical figure of reason, Sophia Western a figure of imagination, Tom Jones a figure of emotion, and Squire Western a figure of instinct. The action of the novel, culminating in the marriage of Sophia and Tom, symbolizes the reunification of the disunited elements of mind in an allegorical marriage of imagination with emotion. In connection with this view, the thesis deals at some length with Fielding's theory of the imagination.

The study investigates the manner in which verbal imagery in Shakespeare's plays achieves substance through the corresponding visual imagery of stage effects. Such reinforcement of the verbal by the visual pinpoints important iterative themes, and the dramatic effects of such an emphasis are examined.

The dramatic imagery, that is the combination of verbal and visual elements, is discussed in detail with reference to three plays, Othello, Romeo and Juliet and The Tempest. Essentially the discussion forms a stimulus and a parting of the waters in preparation for further study

title: The Historical Idea of Character and The Canterbury Tales

contributor:
Wood, C.

abstract:
The purpose of this study is to make some distinotions between medieval and modern attitudes and assumptions concerning the individual and his relationship to society, in order to discern Chaucer's metbods and purposes in the characterisation found in some of The Canterbury Tales. Critical dispute which I will summarise in Chapter One, suggests that the assumptions and preconoeptions related to our own idea of "personality" are inappropriate to and misleading in an evaluation of Chaucer's characters.

Tbe fourteenth-century idea of tbe self and of man's relation to society, ultimately to creation, and God, is contrasted with some aspects of our own "self-picture", the implications of our possession of "personality" in Chapter two. I will look briefly at the beliefs to be inferred from the theological doctrine of personalities, and outline some medieval conceptions of the Inner Man, and of his objectives and his inadequacies.

My remaining three cbapters will comprise a detailed study of the characters found in The General Prologue, and The Wife of Bath's Tale. In Chapter Three we shall see how the external details of the portraits implicitly lead to moral assessment, to a knowledge of spiritual condition which reacbes its culminating statement in The Parson's Tale. This chapter applies the findings of the first and second parts of Chapter Two. Chapter Four pursues the ideas of the third section of Chapter Two, medieval ideals and virtues. Constance embodies some of these ideals and qualities; the Man of Law is an elaborate foil for such characteristics. My final chapter explores the characterisation of the Wife of Bath as the presentation of contrasting qualities and attitudes, a conviction and constancy in sinning and falling. In endowing medieval man and medieval characters with "personality" we are presupposing in the man a moral autonomy and a manner of introspection he is unlikely to have expressed, and in literary characters, a verisimilitude, external or "psychological" calculated to elicit the sympathetic identification of the reader. My contention is that Chaucer's characters are highly artificial, that they comprise elements of iconograpby, exemplary materials, theological, literary and contemporary allusion, calculated to arouse a rational response, and ultimately, an ethical judgment.

It examines in the light of these definitions some passages selected from Shaw's plays, pointing out the oracular and often Biblical nature of their rhythm and imagery, and making a distinction between those speeches which are rhetorical or persuasive and those which are poetic or introspective. It then explores in detail the rhythmic dialogue and symbolic significance of three dramas, Major Barbara, Heartbreak House, and Saint Joan, contending that the creative ability which is present in these plays may reasonably be called poetic.

title: ORITIOAL THEORIES IN EIGHTEENTH - CENTURY ENGLAND.

contributor:
B., W. J.
English

abstract:
This thesis began life as an attempt to relate the main critical theories of the eighteenth century to those of the first Romantic poets, and possibly to find reason in this for the rise of criticism as a significant part of literature. This plan, through the shortness of time, has been artificially truncated. The period 1781-1798, from the publication of Johnson's Lives of the Poets to the first edition of the Lyrical Ballads, which is probably most crucial, has had to be ignored. Of course, the progress of critical ideas in toto is not regular, so that many relatively advanced works have been omitted too, though being early in a chronological sense. Most significant of these are Kames' Elements of Oriticism(1762), Dugald Stewart's Elements of the Philosophy of the Human Mind (1792), and Alexander Gerard's An Essay on Taste (1759). It is by such people as these, particularly the first two, that the process of defining subjectivity, and fixing its terminology was perfected. It would seem that from the precision of their findings, Wordsworth and Coleridge were able to formulate theories specifically of poetry and its place in life.

It remains, therefore, to justify the value of the thesis as it stands, as having, nevertheless, an internal coherence. This has been done by the choice of Johnson as a pivotal figure. From an understanding of his opinions it is easy to see all the signs of Romantioism, together with muoh that is neo-classical, and very much that is derived from striotly English eighteenth oentury souroes.

Further to this, ooncurrent with the growing refinement of neo-classicism which undoubtedly marked the age,1 ran a reaction to the early neo-classicism of Pope. This reaction took, in the main, two forms: through the theoretical development of the omagination, and of the passions. The distinction between the "fancy" and the "imagination" became apparent before it was rationalised as such by Coleridge, and there were good reasons, first for the predominance of the "fancy'" and then for its evident insuffioiency, and its ultimate defeat by its suppressed counterpart, the imagination.

The passions, too, became a popular source of poetry, and the Romantic poets' insistence on this in their work besides the faculty of imagination, provides a link between the period I am dealing with in most detail, and the theories of Wordsworth and Coleridge.

This thesis is partly constructed on the simple premise that because many critics mentioned several criteria in almost the same sentence, it is important to investigate the nature of these criteria. On this head, the movement of the critical theories around the quality of the Sublime has been included, as it is, possibly, neo-classicism apart, the single most characteristic interest of the time. It passes out of currency, however, with the Romantics, as a question central to critical theory. Its importance to this study is that it reflects broadly the movements of the times, and depends ultimately on the theory of the passions, and is not itself depended upon.

The logical connection of the occasionally disparate ideas dealt with in this work is partly a result of the fact that the ideas themselves were combined most succesfully by. the Romantics, and neither fully defined nor combined by the critics with whom I have dealt in most detail. It is part of my whole point to stress that pre-Romantic theorists were not often able to make a theory which logically cohered, but usually resorted to a single-minded interest in one artifically separated ingredient.

Though I did not set out to do so, I have found myself trespassing into philosophical grounds, and it has been necessary to simplify these points. In connection with this, I have also found myself referring to twentieth century problems on the nature of reality, and in a sense, the investigation of the terms of the origin of these problems is the most important theme "discover'd not devis'd" in the whole work.

subject: Geography Geography

abstract: McMaster Lake is a 7.2 km² ice-dammed lake ponded against the margin of the Ellesmere Ice Cap, Ellesmere Island; Northwest Territories. The lake occupies a deep structural basin, and was found to be smictic, with a near isothermal temperature profile of 0.0-0.5ºC, and a year round 3m thick ice cover. The lake was observed over three seasons to lose 3-5 m of water rapidly during the month of August. In 1974 the outflow was monitored in Siphon Creek and the Sverdrup River, and a characteristic jokulhlaup hydrograph with a peak discharge of 85 m²/sec was observed. Correlation of the temperature, incoming solar radiation, relative humidity, and precipitation data collected at the McMaster Lakes site with Siphon Creek discharge yields a good explanation of variance in discharge prior to the jokulhlaup. The glaciology of the shelving glacier bordering McMaster Lake was found to be instrumental in the lake drainage behaviour, and the origins and activity of the ice shelf are documented. Consideration of the available data on McMaster Lake, and a review of existing theories leads to the proposal of a modified barrier flotation mechanism for the drainage of McMaster Lake.

abstract: The first chapter is an attempt to demonstrate the relationship between certain key features of Virginia Woolf's work and the artistic and philosophical theories of the English Romantics. Particular attention is focused upon the common distinction between two contrasting orders of experience, which are metaphorically denominated "the depths" and "the surface" in the writings of Virginia Woolf. Discussion follows of the pattern or rhythm, designated "the Rebirth archetype", into which these two states often fall, and its significance both in art and in life. Within this context, as well as that of Romantic myth in general, Mrs Dalloway, To the Lighthouse. and the final section of The Waves are examined in the following three chapters.

title: "Who Knows Not Colin Clout:" The Apparatus of The Shepheardes Calender

contributor:
Cain, Thomas H.
English

abstract:
This thesis examines the apparatus added to The Shepheardes Calender by E.K. and the woodcuts to determine how, or whether, they function as criticism in the modern sense of the term. The arguments are generally not in sympathy with the eclogues to Which they pertain, although some of them do highlight the advertising aspects of the Calender. The woodcuts, however, besides showing many instances of one-to-one correspondence with the eclogues, often interpret and even extend the poem along sympathetic lines. This contrast between the arguments and the woodcuts, both appearing before the text of the eclogue, suggests that a cross-reference between E.K.'s verbal and the artist's visual representation, and between these and the text, is intended, and that these parts of the apparatus constitute a lesson in reading Spenser.

The, glosses contain much padding, many errors, and some misleading interpretations, which implies that their purpose is not criticism. They are to be seen rather than read, for their cumulative effect is to make the Calender look like, a heavily glossed edition of a classical author. That is, E.K.'s material is primarily an advertising strategy, as is much of the poem itself. In his introduction, arguments, and glosses he often works directly to promote the "New Poete," and more often obliquely by producing an apparatus whose existence takes priority over the content.

title: Theme and Form in the Work of W.B.Yeats 1935-1939

contributor:
John, B.
English

abstract:
In this thesis I have aimed to establish certain thematic and formal emphases in the work of W.B. Yeats during the last four years of his life. The variety of Yeats's interest in these years was as great as in any other period of his life; I have chosen to explore those interests which brought him into contact closely with public concerns and with other writers. Thus I deal with Yeats as a political philosopher and patriot, RS a founder of the Irish Academy of Letters, as a broadcaster, as editor of an important verse anthology and as a correspondent on poetry with a fellow poet. By quoting widely from primary sources I have tried to allow Yeats to explain himself My purpose has been historical exploration rather than literary criticism, and so my approach is geared strongly to biography and bibliography especially in the first two chapters. The picture of Yeats to emerge will be that of a poet strongly traditional in his views of politics and aesthetics, defining his world view sharply in all his work. Although 1 concentrate on Yeats in all aspects as an Irish writer, for him Ireland was of course a rnicrocosm of Europe and the modern world.

 Chapter One begins from a point strictly outside the chronology of the thesis in order to present necessary introductory material; it explores the nature of Yeats's patriotism and his political views, demonstrating his intense concern for the Irish nation as it defined itself in a world troubled by crisis. Chapter Two deals with Yeats as a discursive theorist on modern poetry and the lyric, much concerned with the problem of poetry as a public art. Thr following chapter turns attention to textual natters; although I have called it “ The Imagery of Music” it also explores briefly aspects of Yeats's late lyrical technique including his use of refrain in poems. Chapter Four completes the study by examining the two last plays in terms of the material of the preceding chapters. I must emphasise that my interest is not primarily critical. There are many books and articles which treat the plays in literary critical terms or as objects for dramatic form, dealing essentially with the familiar material of Yeats's lat period.

 I find that the predominant theme of the late Yeats is the ideal character of Ireland, its love of individuality and heroism. The predominant formal preoccupation is with traditional poetry, the folk song and the ballad. All of Yeats's work – poetry, plays and prose works – considered together, illuminates these preoccupations.

In my examination I have used all the genuine Traherne material available to me, omitting a consideration of the Hexameron and Meditations and Devotions on the Life of Christ because of their dubious authenticity, in an attempt to provide a comprehensive introductory examination of Traherne' s· main themes, methods, and philosophy.

title: John Donne: The Mitcham Years, 1606-1611

abstract:
This thesis represents an attempt to define the nature of the intense personal crisis Donne suffered in the Mitcham years, 1606-1611. Interpreted as a modified spiritual autobiography, the poetry written in these years reflects the crisis itself and the ensuing search for resolution of personal conflicts.

The years 1607-1609 were a period of transition: the earliest divine poems reflect an attempted self-accommodation to formal religious devotion, while the late love lyrics reveal the disillusion accompanying the failure of sustained human relation in love of woman. Significant in this period is Donne's intense personal relationship with Lucy, Countess of Bedford. The collapse of this relationship in 1609 contributed to a crisis compounded of poverty, illness, and profound dejection of spirit. Donne's sense of inner incompletion, the need for the security and assurance of a sustaining personal relation, is poignantly expressed in the late lyrics and in the 'Holy Sonnets': love of woman and love of God appear as opposite foci in the search for a sufficient personal object of devotion.

In the 'Holy Sonnets' renewed consciousness of repressed guilt and fear reinforces the urgency of this search. The resolution was both personal and religious: Donne would always live in fear, but henceforth fear tempered by recognition of an acceptance by a loving father in God. The self-renewal achieved with the resolution of the 1609 crisis represents an impressive human accomplishment. The 'Holy Sonnets' themselves illustrate the reparative function of poetry in achieving a fundamental redirection and reogranization of the self.

abstract:
This thesis is concerned with the general form of those one dimensional formal group laws over any field A which are given as rational functions over A. After having determined an exact expression for any rational function which is a formal group law over A, an investigation is made into the category whose objects are the rational formal group morphisms which are given by rational functions. The isomorphism classes of this category are then completely determined, and, are shown to be essentially equivalent to the classes of congruent quadratic forms over A, provided, of course, that the charactersistic of A is different from two.

Finally, we generalize most of the results in the case of fields to the case of semi-prime rings, making a suitable definition of a rational formal group law over a semi-prime ring. In particular, we show that semi-primeness determines, and, is determined by, the general form of rational formal groups over commutative rings with unit.

title: Oscar Wilde, Philosopher And Aesthete: An Examination Of The Evolving Aesthetic Of Oscar Wilde

abstract:
Oscar Wilde was one of the many men of intellectual stature in the nineteenth century who openly embraced and lauded Darwin's theory of evolution. However, with Wilde in particular, there is a kind of irony involved in this simple fact, since Wilde himself was a man highly aware and conscious of his own consistent and personal evolution. He anticipated, among others, Lawrence's feeling and belief that the "old stable ego" had had its day, and that human psychology was infinitely complex and required much insight and examination to be understood. For this reason any study of Wilde must be development in nature, because his ideas and theories change considerably over the short period of his life, although more frequently and consistently in the period prior to his eventual success as a playwright.

Wilde was always developing, always undergoing a process of change. His work and his development is therefore essentially linear. No work written by Wilde is preconceived; the act of conception and the process of creation take place Simultaneously. Consequently~it is necessary to study Wilde linearly rather than to separate, for purposes of examination, his criticism from his art. One idea develops out of another, much like the effect of a tree branching. One could term the process metaphysical, or one could term it Socratic, but in Hegelian fashion he begins always with an assumed thesis and ends always with a new synthesis.

The period under examination in this thesis is essentially that between the years "1885 - 1891", although an earlier essay "The Rise of Historical Criticism" is also included to provide focus. This early essay illustrates the extent to which Wilde's ideas were firmly rooted in Cartesian notions of reality. Romanticism, in the early nineteenth century is the first really major attack on this particular consciousness, and the Decadence of the "fin de siecle", as an outgrowth of Romanticism in effect reestablished the older, more mystical Romantic antagonism. Wilde's evolution therefore comprehends the growth of a new anti-Cartesian consciousness.

“The Truth of Masks" is Wilde's first "Romantic” point of departure, although it is Romantic only to the extent that Wilde is discussing his own reactions to and expectations of the experience of theatre. It is decadent, and therefore something new,to the extent that Wilde is interested in very specific and isolated effects rather than the effect as a whole. The essay itself is a very important shift away from traditional concepts and modes of thought. Wilde is not analysing theatre per se, in isolation from his own experience, but rather using and therefore trusting his own experience to create his own criteria. The fairy tales both support and deny this kind of "self-oriented" reality.

It is very clear that during the period when he is both writing his best criticism and his two books of fairy tales there exists in his mind a desire for some external Cartesian order or set of principles by which to evaluate reality, and an equally strong desire to cleanse himself of the particular assumptions of his own society and determine his own rationale for thought and behaviour. The fairy tales on the whole depict Wilde's growing skepticism in respect to assuming any set of principles not initially his own. Christianity figures very strongly in many of the tales, until specifically in "The Devoted Friend", Wilde forces himself to see the emptiness of the principles as they are practised.

In the later criticism and The Picture of Dorian Gray Art is evaluated by Wilde first, very much like Arnold, as a replacement for religion, then as a possible destroyer of selfhood and imagination, and finally, in a return to many of his initial ideas in "The Truth of Masks", as a form of experience. At this point he originates his concept of "the Critic as Artist" which in itself is a minor revolution in thought. By placing the critic on a par with the artist, Wilde's effectively destroys any concept of the mind as a "tabula rasa" or mere receptor for information. He insists that art is a product of both the creativity of the artist and the critic, and therefore constitutes a form of legitimate experience for the critic.
Arriving at such an assumption Wilde is forced to discard a very extensive body of thought; this thesis shall attempt to examine the process by which Wilde comes to do so and in turn formulate his own theories of experience and art and to discuss the relevance or significance of Wilde t s theories as they evolve.

subject: English Language and Literature

abstract: Wuthering Heights has been a centre of argument for literary critics for over one hundred and thirty years. The following discussion offers insights into the way Emily Brontë may have conceived the novel's structure on the basis of an Elizabethan dramatic design -- Shakespeare's tragedies being generally the model. At the same time, the narrative -- being an unusual feature of the book as far as it concerns the mid-nineteenth century -- looks forward to the kind of techniques Joseph Conrad was later to use. Together, the historical design of the novel's structure and its then futuristic narrative method, produce a unique work of genius -- one reason, perhaps, why Wuthering Heights in 1980 still attracts attention from readers and critics alike.

Although development analysts have long stressed that education in the economically underdevelopment countries (E.U.C.'s) must be relevant to the environment and 'practical' in nature, there is a great deal still to be done to determine better 'theory' of the role of education in developing the E.U.C.'s. Values need to be established, terms defined, the significant variables located, and hypotheses and generalizations must be suggested, tested and modified.
 With theses limitations in mind, this thesis includes a comparative analysis of the British and French educational policies in three West African colonies. The purpose of this analysis is to obtain some generalizations regarding educational policy which is suitable at the present time for West Africa. The thesis also contains an appendix in which the author looks closely at the traditional social structures in Northern Nigeria. An attempt is made to show the retarding effects of the failure to introduce formal educational institutions in the North, as they were in the South. The author concludes that there would be no point in restoring the Federation (assuming this were possible), once the civil war is finished, unless the approach to education in the North could be immediately revamped, that is, brought into line with the prescriptions for educational policy set out in the body of the thesis.

abstract:
This thesis offers opportunities to a segment of our population who sometimes go unnoticed in literature on fathers: African Caribbean fathers. Specifically, this thesis offers fathers an opportunity to define themselves and inform readers of what factors influences them, and how this is translated into the larger picture of their perception and interaction with their own children and service providers, specifically child protection workers at Children Aid Societies.

By no means are the findings in this study conclusive or to be generalized to the larger population. The sample size was small, however, there is value in understanding how these fathers experience fatherhood and what they feel that they do as fathers.

The literature of African Caribbean as fathers is sparse. There is a tremendous amount of negative views on Black fathers, which appears to cross over all thresholds and continents. At the same time, there is a small section of positive literature which looks at the way men define themselves as fathers, and this makes it worthwhile in terms of utilizing a view which can look at the bigger and smaller issues.

title: The Indian in Poetry and His Relationship to Canadian Nationalism: A Study of the Late Nineteenth Century and the Mid Twentieth Century

contributor:
Shrive, N.
English

abstract: This thesis studies the relationship between the use of the "figure qf the Indian in poetry and the concerns of Canadian nationalism. In the two intensely nationalistic periods that are focused on, the late nineteenth century and the mid twentieth, the Indian becomes the symbolic link to a sense of Canadian unity and patriotism, playing the role of the Canadian hero and the innocent and noble savage. Yet the Indian also becomes the implacable foe, functionning as a force detrimental to the development of a sincere Canadian sense of security and comfort in a homeland. The varying roles of the Indian symbolically represent both the innocent promise and the terror offered by the Canadian landscape to its new inhabitants. The Canadian must come to terms with both before he can achieve a true sense of nationalism. The presence of recurring themes in both periods in connection with the Indian in poetry attests to the fact that the Canadian mentality has yet to achieve the understanding necessary for the creation of such a sense of nationalism.

title: Characterization in the Novels of Fanny Burney

contributor:
Norton, R. W.
English

abstract: The thesis examines Miss Burney's methods of characterization and the extent to which they succeed or fail. Cahpter One is mainly biographical. Chapter Two attempts to show where Miss Burney's originality lies and how she adapts her methods of characterization from earlier fiction or from the stage. Chapters Three and Four, which support the general scheme outlined in Chapter Two with detailed character studies, are devoted to selected characters from all her novels, though the emphasis is on Evelina and Cecilia. The analysis of character is broadly based on Forster's classification into flat and round and the thesis draws more attention to Miss Burney's debt to the stage than previous critics have chosen to do.

title: Joseph Conrad's Nostromo: The Concept of Time

contributor:
Bishop, Alan
English

abstract: It is my view that an understanding of the concept of time is central to a reading of Nostromo. For Joseph Conrad, the community of mankind was held together by the illusion of civilization. Behind this illusion exists a hostile, malignant universe that reveals itself, at will, to certain individuals. Conrad's major fiction was directed to exposing this underlying reality and shattering the illusion. Thus the radical time shifts within the form of Nostromo effectively destroy what is essential to preserving that illusion-- an unquestioning belief in sequential, coherent time. The individual for whom this sense of time no longer exists penetrates the illusion to discover the destructive element in reality. The destruction of chronological time and the discovery of reality are, in Conrad's fiction, achieved through a perfect union of theme and technique. This thesis will not attempt to separate these aspects of Nostromo, but rather it assumes that theme and technique are one.

abstract:
In the eighth chapter of his Aspects of the Novel, E.M.Forster considers "something which springs mainly out of the plot, and to which the characters and any other element present also contribute." Borrowing his terms from painting and music, Forster calls this aspect "pattern" and "rhythm".
 Forster's notions on pattern and rhythm are applied to his three major novels, The Longest Journey, Howards End and A Passage to India, in the thesis, to see how far his achievements matched his intentions. The results of the investigation are also seen in relation to the needs of the twentieth-century man, in particular, and, in general, to the needs of men at all times.

title: "A revolution in the human spirit": An Analysis of Impulse and Impulsive Behaviour in Ibsen's Drama

contributor:
Juneja, Mohan
English

abstract: This thesis will examine the role impulse and impulsive behaviour play in the major works of Henrik Ibsen. The twelve plays examined have been broken down into four chapters, differentiated by the type of impulse being examined. Peer Gynt, A Doll's House, and An Enemy of the People have been treated together as the studies of the immature, impulsive character who finds himself restricted by societal impositions. Chapter II examines Ghosts, John Gabriel Borkman, and The Lady from the Sea as plays in which a character's instinctual nature has been wilfully repressed, resulting in human tragedy in Ghosts and John Gabriel Borkman, and social harmony in the third play. The Wild Duck, Rosmersholm, and Little Eyolf analyze the consequences of engaging in overtly impulsive behaviour. Through the efforts of a persuasive character who attempts to initiate an unimpulsive character into a new more instinctive type of behaviour, lives are destroyed in the first two plays and redeemed in the third. The final three plays to be considered, Hedda Gabler, The Master Builder, and When We Dead Awaken, concern themselves with the impulsively creative character and the paradoxical nature of the artistic act. In a final chapter, this emphasis on impulse will be related to Ibsen's primary ideas about human freedom and liberty.

title: The First Stage in the Itinerary of Ua Cleirigh: A Study of Austin Clarke's Early Poetry

abstract:
From The Vengeance of Fionn (1917), written in imitation of Herbert Trench's Deirdre Wed, Austin Clarke was to go on to develop his own poetic voice. This thesis, after comparing these two poems, seeks to show the path that Clarke adopts in his early epic poetry. This stage of the young Clarke's poetic journey reveals how he uses the Irish mythological material as private and pUblic symbols and how its use, together with his adaptation of Gaelic prosody and Gaelic genres, places him in a direct line of succession to the Gaelic fili.

The thesis traces the change of the poet's focus, from ancient saga to the Celtic-Romanesque period, from the public and private soul-building of the first stage to the public and private soul-searching of the second, from the fili of patriotism to the fili of the satire and the curse. Clarke, however, is constantly a Gaelic poet writing in English verse, a fact which gives a freshness, vividness and natural beauty to his poetry. Clarke's achievement makes him one of the most important influences on Irish verse since Yeats.

title: A Critical Introduction to the Work of James Plunkett

abstract: This thesis offers a basic, critical introduction to the work of the contemporary Irish writer, James Plunkett. As there is virtually no criticism of the writer, the work itself is examined in some depth. Strumpet City and Farewell Companions are discussed as novels which can be read in sequence, thus providing a unique view of Irish life between 1907 and 1947, and as individual works which stand on their own merit. Plunkett's growth as a writer is observed through his Collected Short Stories. The Gems She Wore: A Book of Irish Places is used as background material. In conclusion, a basic philosophy of brotherhood is seen as the uniting theme of all Plunkett's work.

title: Imagery and Structure in The Imperialist by Sara Jeannette Duncan

contributor:
Ballstadt, Carl
English

abstract:
The Imperialist is a novel that studies both personal and national destiny. Sara Jeannette Duncan unifies her study of the destinies of her characters, and of England and Canada by employing a series of images that relate to both character and nation, and by means of a symbolic structure that also allows the reader to identify the fate of specific characters with Canadian or British national identity. The techniques used by Duncan in achieving this unity of imagery and structure amply reward critical attention.

Chapter One ("Interrelated Plots") deals with the career of Lorne Murchison, and the romance between Advena Murchison and Hugh Finlay. Chapter Two ("Interrelated Imagery") examines Duncan's organisation of subsidiary themes in the novel. In Chapter Three ("Interrelated Politics") the concept of imperialism, as perceived in The Imperialist, is discussed in terms of Duncan's imagery.

abstract: Four aspects of the "Schei River" basin, a 91.2 km² glacierized catchment at the head of Vendom Fiord, Ellesmere Island (78ºN, 82ºW), were investigated during the 1974 runoff season. The postglacial evolution of the basin is studied through comparison of the present river system with a reconstruction of drainage at the time of deglaciation. The three month runoff regime of the basin is analysed in terms of glacial and nival contributions, response to meteorologic inputs and ice-damming and an approximate water-balance is calculated. Measurements of concentration and load of suspend and dissolved sediment are discussed in terms of controlling factors and geomorphic implications. Finally, the fluvial and glaciofluvial Landforms of the basin are described, with emphasis on the cobble-size distribution of sandur deposits.

contributor:
Morton, R. E.
English

abstract:
Mrs. Cowley's plays have not previously been the subject of separate critical study, and this thesis is therefore mainly concerned with the estabiishment of some preliminary oritical co-ordinates. With the exception of The Belle's Stratagem, none of the plays discussed has received more than incidental comment; two of them are still unpublished.

The Introduction supplies a brief chronological outline of her dramatic career, giving essential information on each of her plays. In the four chapters which follow, a topical approach is taken, each chapter being concerned with a leading critioal theme:

II. Taste. Individual characters isolated by some excess or eccentricity of "taste" are considered, and the term "taste" is discussed. The roles played by the comedian John Edwin are selected for separate treatment.

III. Marriage. This chapter discusses Mrs. Cowley's ideal of marriage as it is presented in her comedies. Recurrent character patterns, and the roles played by Lewis and Miss Younge, are also considered.

IV. Society. Mrs. Cowley's satirical treatment of the follies of fashionable society is seen to be modified by her belief in the possible rational enjoyment of society, and in the value of the traditional English virtues.

V. Patriotism. Mrs. Cowley's view of the corrupting influence of foreign manners on English society, together with the more positive side of her patriotism, are examined as the basis of her ideal of Englishness. This ideal is seen as the conceptual centre of her comedies.

In this thesis, I attempt to examine the function of the minor rustic characters in four of the major novels of Thomas Hardy. The four novels are, Far from the Madding Crowd, The Mayor of Casterbridge, Tess of the d'Urbervilles and Jude the Obscure.

The purpose of this examination is to show to what extent the minor rustics help to reveal the theme of marriage, chastity, the double standard and sexual freedom. They do this either by furthering, or by not influencing, the plot; through the delineation of the characters of the protagonists; by their contribution to the humour, comic relief, and the chorus of the novels; and finally, by their rural values.

title: The Clergy in English-Canadian Fiction

abstract:
The stress in the study of the clergy in Canadian fiction is on the clergyman's position in both the Church and society. The early novels, those written before 1920, are divided into two categories according to their common traits. The novels in the first category, the "evangelical romance," which is discussed in the first chapter, are found to have a surprisingly large number of common traits. Of these evangelical romances those of Ralph Connor were immensely popular when they were first written and until well on into the 1930's. Various factors in the novels account for the popularity. Although many of these features are no longer popular, Connor's novels ae still valuable for what they reveal of life in the early Canadian West and especially of the importance and nature of its religious life and its clergyman. Of the seven evangelical romances studies, Ernest Seton's The Preacher of Cedar Mountain is judged to be the best by modern standards.

In the second chapter, seven "ecclesiastical" novels ae discussed. These novels have a number of features which clearly distinguish them from the evangelical romances. The seven are subdivided into two major groups. The first four novels discussed, The Lone Furrow, Committed to His Charge, Sunshine Sketches, and Arcadian Adventure's are all fairly objective in point of view and critical of laity and clergy. The miniters in the remaining three ecclesiastical novels are more like those in the evangelical novels, as are the laymen.

The majority of clergymen and laymen in modern Canadian fection, which is discussed is chapter three, follow in the tradition of the first four ecclesiastical novels. The clergymen are discussed in two groups: six "prêtres manqué's" and three successful hypocrites. Ministers like those in the evangelical romances seem to have vanished from Canadian fiction, as do the devout churchmen of the second group of ecclesiastical novels. The peculiar nature of most of the clergymen in modern Canadian fiction reflects a decline in the importance of the church in society in general.

title: Time and Narrative Technique in Margaret Laurence's Manawaka Novels and A Bird in the House

abstract:
The relation between time and narrative technique in The Stone Angel, A Bird in the House and The Diviners is the relation between content and form. Margaret Laurence states in her lecture "Gadgetry or Growing? ... Form and Voice in the Novel", that she has no interest in form for its own sake:

I am not concerned at all about trying forms and means of expression which are new simply for their own sake or for the sake of doing something different...l am concerned mainly, I think, with finding a form which will enable a novel to reveal itself...
(The Manawaka World of Margaret Laurence, p .129 )

The form of each of the three works that I have named is based on various uses of a flashback technique, and the form points to one of the most important themes in the works, which is that of the importance of an individual's past to the person she is in the present, and can become in the future. Laurence shows us over and over again that, as Morag, the most articulate of her narrators discovers, we have to go home again: "You Can't Go Home Again, said Thomas Wolfe. Morag wonders now if it may be the reverse which is true. You have to go home again, in some way or other." (The Diviners, p.248) The necessity of going home does not necessarily imply a physical journey to Manawaka, which is home for the narrators of the five works that I discuss. The important journey is the imaginative journey through time to a past that must be. relived and revalued until the traveller is content that he stands in a proper relation to his past. In my analysis of the relation of time to narrative technique, I attempt to demonstrate the importance of the novel's means of expression to what it expresses.

I have included A Jest of God and. The Fire-Dwellers because I see a similar treatment of time in them, even though the techniques of narration that Laurence uses in these two novels do not lend themselves to the same kind of discussion as do The Stone Angel, A Bird in the House and The Diviners. The five works, The Stone Angel, A Jest of God, The Fire-Dwellers, A Bird in the House and The Diviners, invite discussion as a group because they all have as either an important setting or a point of reference, the fictional town of Manawaka. They are also linked by a similar treatment of the theme of time.

title: The Marriage of Draupadī in the Hindu and Jaina Mahābhārata

contributor:
Granoff, Phyllis
Religious Studies

subject: Religion Religion

abstract:
Broadly speaking, this thesis constitutes an examination of the history and development of the great Indian epic Mahābhārata, or the Great Story of the Descendents of Bharata. More specifically, this thesis attempts to shed light upon the origin of the Jaina Mahābhārata tradition and to elucidate its interactions with the Hindu Mahābhārata tradition over approximately two millennia. The discussion of these issues is focused upon one particular episode from the epic: the Marriage of Princess Draupadī to the five sons of King Pāṇḍu (i.e. the five pāṇḍavas).

Whether the Jainas had their own ancient Mahābhārata tradition that developed independently and in parallel with the Hindu version or they simply appropriated the epic from the Hindus and self-consciously transformed it into a Jaina Mahābhārata has been a point of disagreement among scholars. It is concluded in this thesis that the Jainas did have an ancient and distinctive Mahābhārata tradition, though the tradition was rather modest and of limited importance to the early Jaina community. Over a period of approximately 1500- 2000 years, however, and under the influence of the popularity of the Hindu Mahābhārata, the Jaina Mahābhārata took on greater prominence in the Jaina community while at the same time becoming less distinctively Jaina and increasingly similar to the Hindu version.

Finally, it is argued here that one particular short tale which is to be found in the oldest extant Hindu version of the Marriage of Draupadī was in fact originally a Jaina tale that was borrowed, adapted, and inserted into the Hindu Mahābhārata at a very early period (i.e. not later than 400 CE, and possibly much earlier).

abstract: MathScheme is a long-range research project being conducted at McMaster University with the aim to develop a mechanized mathematics system in which formal deduction and symbolic computation are integrated from the lowest level. The novel notion of a biform theory that is a combination of an axiomatic theory and an algorithmic theory is used to integrate formal deduction and symbolic computation into a uniform theory. A major focus of the project has currently been on building a library of formalized mathematics called the MathScheme Library. The MathScheme Library is based on the little theories method in which a portion of mathematical knowledge is represented as a network of biform theories interconnected via theory morphisms. In this thesis, we describe a systematic explanation of the underlying techniques which have been used for the construction of the MathScheme Library. Then we describe several algebraic constructions that can derive new useful machinery by leveraging the information extracted from a theory. For instance, we show a construction that can reify the term algebra of a (possibly multi-sorted) theory as an inductive data type.

title: Improving Word Pronunciation by Visually Emphasizing Letter Groups

contributor:
Brooks, L. R.
Psychology

subject: Psychology Psychology

abstract:
Adults experience a surprising degree of difficulty when they attempt to sound out words written with novel alphabetic characters. This difficulty is experienced despite extensive prior practice on identifying those characters individually, despite many years of prior experience with the English alphabetic system (Brooks and Anderson, 1976). Such difficulties seem in some ways akin to the "blending difficulties" experienced by beginning readers. The experiments in this thesis were designed to test whether this adult blending difficulty might in part be due to a disruption of the adults' ability to segment letters into groups that are relevant for further processing.

Experiment I demonstrated that response time to identify words written with novel characters could be reduced by visually emphasizing the vowels, thereby making orthographically relevant letter groups more salient. Moreover, practice on identifying vowel enhanced words resulted in improved performance on a new list of unenhanced words. Experiment II showed that performance on vowel enhanced words was also improved for both regularly and irregularly spelled words even when they are written with familiar Roman characters. These data are discussed in terms of several possible components of word identification.

The fact that the effect was found for both artificial and Roman letters and for both regularly and irregularly spelled words suggests that vowel enhancement might aid word identification under a wide variety of conditions. Such generality offers some grounds for the speculation that vowel enhancement could improve word identification skills and perhaps aid in establishing appropriate visual inspection habits in children.

abstract:
Getting tough on crime through harsh prison sentences is often seen as the most effective way to reduce offences. Reviews of the effects of incarceration suggest that long, harsh sentences of imprisonment do not deter crime or rehabilitate offenders (Wright, 1991) and are not likely to achieve the desired ends of the public (Wilson, Picheca, & Prinzo, 2005). The values of restorative justice offer an alternative to the harsh punishment of incarceration. Despite the increased attention given to restorative justice, the concept still remains somewhat problematic to define as numerous responses to criminal behaviour may fall under the 'restorative umbrella' (Latimer, Dowden & Muise: 2001). Some programs and policies have taken the title 'restorative' when they actually do not reflect the principles, including repaying the harm done to the victim or community.

This interview study explored the experiences of offenders and community agency representatives in the Intermittent Community Work Program (ICWP), a program of the Ontario Ministry of Community Safety and Correctional Services. ICWP provides the opportunity for eligible intermittently sentenced provincial offenders to serve their sentence in the community as opposed to in jail. The research responds to a gap in our knowledge about what happens in the ICWP from the perspectives of those who actually participate in it. This research examined whether or not the ICWP met restorative justice criteria as determined by program participants and community agency representatives.

The ICWP was found to not meet the restorative justice criteria, but was still determined to be a better alternative than prison. Program participants defined benefits in terms of making connections in the community, and avoiding incarceration. Community agencies defined benefits in terms ofthe provision of community services that would not otherwise be provided. However, both also revealed problematic aspects of the program. This research supports the increased participation of the offender and community agency representatives in decision-making in the ICWP.

title: Phylogenetic and in silico Functional Analyses of the Cytochrome P450 Families 2 and 4

contributor:
Wilson, J. Y.
Biology

abstract: The CYP superfamily is present in all domains of life and can metabolize an array of exogenous and endogenous compounds. In vertebrates, the CYP2 family is the largest and most diverse family; in mammals this CYP family is important for drug metabolism. The CYP4 family is the major family involved in the metabolism of fatty acids and eicosanoids. Both families have uncertain phylogenetic relationships amongst the vertebrate subfamilies and functional studies in non-mammalian vertebrates are limited. Vertebrate CYPs usually present a one-to-one subfamily relationship, yet in the CYP2 and in some CYP4 subfamilies this does not hold true, thus extrapolating functional understanding is difficult. Phylogenetic trees were constructed for the CYP2 and CYP4 families using robust phylogenetic methods (maximum likelihood and Bayesian inference) and sequences from all vertebrate classes. An emphasis was placed upon using the full complement of the family from species with completed genomes, particularly from mammalian and actinopterygian species. In the CYP2 phylogeny, subfamilies from distinct vertebrate classes were rarely clustered. CYP substrate recognition sites (SRSs), regions previously proposed as important for determining differences in substrate specificity between CYP genes, did not have elevated rates of evolution in either CYP2 or CYP4 analyses. The CYP4 phylogeny supported the placement of the CYP4V clade with invertebrate sequences and resolved inconsistencies in the placement of mammalian CYP4A/4X/4Z and 4B subfamilies. The evolution of the CYP4T and CYP4B subfamilies will need more consideration. In silico functional analyses raised testable hypotheses regarding the CYP4X and CYP4F22 genes. CYP4X was hypothesized to selectively metabolize long chain fatty acid amides while CYP4F22 was proposed to have overlapping function with other CYP4F genes with metabolic activity towards leukotrienes. Functional testing within the CYP4F clade should begin with long chain fatty acids and eicosanoids, such as leukotriene B4.

abstract: The theory of natural law is analysed in relation to the concept of a right to resistance. A Western liberal tradition is posited as identified with Cicero and the Stoics, Aquinas, and Locke. The Lockean doctrine of resistance is particularly noted in connection with the American Revolution. This doctrine is argued as deficient in its failure to emphasise non-violent resistance. The central argument of this paper is therefore that, according to the theory of natural law, resistance to government should initially be expressed in terms of non-violent resistance. Certain objections to this argument are also considered.

The analysis finds serious flaws in the City's current approach, related to a lack of gender equity structures and mechanisms, a lack of interest in, and resources allocated to, such structures and mechanisms, and a lack of civic engagement of women, which forms a part of the City's overall democratic deficit. Structures and mechanisms implemented in other cities in order to promote gender equity are explored in order to provide the City with successful possibilities to consider. A proposed six-stage model categorizes various levels of commitment that cities have demonstrated towards achieving gender equity. This model allows cities, such as Toronto, to assess their individual progress on gender equity relative to other cities and to better understand the need to increase their efforts. Lastly, recommendations to the City of Toronto to enhance its gender equity approach are discussed. Despite the limitations of this study, the author believes it was highly necessary to document and disseminate the issues related to the City of Toronto's approach to gender equity in order to open up productive dialogue between the City and the community and to motivate effective, equity-enhancing change in a timely manner.

abstract:
The ability of vertical axis wind turbines to operate effectively in the presence of highly unstable, turbulent wind flow patterns makes them ideal candidates for small scale applications in urban environments, where enatic wind flow patterns are quite common. Their axisymmetric nature allows for wind energy extraction during conditions of rapidly varying wind direction, and their base mounted generator location permits relatively easy maintenance, making them a more suitable design for small scale urban installations as compared with traditional horizontal axis turbines. Wind tunnel experiments were canied out on a small scale, high solidity, three-bladed Danieus wind turbine with canted (tilted) blades. The effects of preset blade pitch (β =+2.5°, -1.5°, -3.5° and -5.5°) and of aerodynamic fences were investigated at high Reynolds numbers (>500,000) for their effect on power performance while simultaneously characterizing the flow behaviour on a section of the inner blade surface using Mylar tufts and a shaft-mounted video camera. The excitation response of the turbine was also measured. The results are compared to a set of similar straight blades.

The results of pitching the canted blades show that the power performance increases up to CPmax =0.28 for increasing outward blade pitch, to a best observed pitch of β = -3.5° after which the power performance decreases. Canted blades show acute sensitivity to inwards pitch where the power coefficient dropped to CPmax =0.06 at β =
+2.5°. The power coefficient observed for canted blades was CPmax = 0.29 at 9 m/s wind speed which was slightly higher than CPmax = 0.26 measured for the equivalent set of straight blades that were tested at the same preset pitch (β = -3.5°) at 10 m/s wind speed. The maximum power coefficient occurred at a higher blade speed ratio for canted blades ( λ =2.15) compared to straight blades (λ = 1.7) despite nearly identical solidities (σ = 0.45 for canted blades versus σ =0.43 for straight blades). Aerodynamic fences improve the power performance of canted blades to CPmax =0.29 at 8 mls wind speed to and CPmax =0.31 at 10 mls wind speed and reduce the speed at which peak power occurs to λ =1.9. Aerodynamic fences do not noticeably change the power performance of straight blades.

Flow visualization using Mylar tufts attached to the inside blade surface indicated that canted blades experience reversed flow exclusively during the upwind pass of their rotation at peak power. Overall, canted blades experience less reversed flow than straight blades at the same blade speed ratio and only develop minor reversed flow during the downwind pass for blade speed ratios substantially below peak power where straight blades experience significantly more reversed flow. Aerodynamic fences further reduce the amount of reversed flow on canted blades, especially directly below the fence.

Due to differences in the peak operating speeds and the primary natural frequencies of the wind turbine with canted blades and straight blades, a direct comparison of the excitation response of canted blades and straight blades is not presently possible. However, normalizing the data suggests that canted blades do show reduced excitation response over straight blades.

This study shows that the Current set of canted blades produces acceptable power levels, with the potential for further refinements to improve performance, and suggests that reduced excitation response can be achieved with canted blades.

title: Modeling. System Identification and Control of a Belt Drive System

contributor:
Habibi, Saeid
Mechanical Engineering

abstract: Belt drives have been serving the industry for a long period. Certain features of belt drives such as slippage, tension fluctuations, and sliding of the belt on the pulleys lead to highly nonlinear deformation, large rigid body motion, dynamical contact with sticking and slipping zones and cyclic tension. The performance of motion control for belt drives is important in many industrial fields and is affected by these factors. Advanced control can improve robustness of belt drive and result in a faster dynamic response and more accuracy. The Purpose of this project is to develop a mathematical model of an experimental belt drive system through physical modeling and system identification. This model is then used for the design of an advanced robust discrete-time controller. An extensive literature review is provided, covering modeling and control of belt drive system as well as sliding mode control (SMC) theory. Physical modeling is carried out for an experimental system followed by system identification. Both the physical and the identified models are used to analyze and investigate the characteristics of the system. Different control approaches such as discrete-time proportional integral derivative (DPID) and discrete-time sliding mode control (DSMC) are designed and implemented. The results are compared and conclusions are drawn from both control approaches.

Roberts, L.E.

subject: Psychology Psychology

abstract: Punishment training was carried out in the three experiments in an attempt to operantly condition heart rate in the paralyzed rat. A fourth experiment compared the effect of two paralyzing agents, d-tubocurarine and succinylcholine, on cardiovascular and electrodermal responding in an attempt to improve the paralyzed preparation. Reliable bidirectional differences in heart rate were produced in two of the learning experiments, one using d-tubocurarine and the other employing succinylcholine as the paralyzing agent. In a third experiment, rats paralyzed with succinylcholine failed to display bidirectional differences in heart rate by the end of conditioning. The bidirectional changes that were produced were specific to the cardiac response. Skin-potential responding was not systematically affected by punishment training. Alternative interpretations other than operant conditioning are considered and the current status of operant conditioning of autonomic responses under curare is evaluated.

title: The effects of low glucose on catecholamine secretion from neonatal adrenomedullary chromaffin cells

contributor:
Nurse, Colin A.
Biology

subject: Biology Biology

abstract:
Glucose is the primary metabolic fuel in mammalian fetuses, yet mammals are incapable of endogenous glucose production until several hours after birth. Thus, when the maternal supply of glucose ceases at birth there is a transient hypoglycemia in the first few hours of life. This hypoglycemia places the newborn at increased risk of brain damage, especially in newborns of diabetic mothers, premature infants, and newborns small-for-gestational-age. In newborns hypoglycemia evokes a surge in circulating catecholamines and glucagon and a fall in insulin, which triggers the breakdown of glycogen in liver hepatocytes. While this counterregulatory hormonal surge occurs in adult mammals the mechanisms of glucose-sensing differ. In adults, neurons in the ventromedial hypothalamus sense glucose and initiate the sympathoadrenal release of catecholamines; however the adrenal gland is not functionally mature until several weeks after birth. Moreover, while glucose acts directly on adult pancreatic a cells to elicit glucagon secretion, these cells are glucose-insensitive until several weeks after birth. Thus, I proposed that neonatal adrenomedullary chromaffin cells (AMC) are direct glucose-sensors which secrete catecholamines in response to low glucose in the perinatal period.

I used carbon fiber amperometry to measure quantal catecholamine release in response to low glucose (aglycemia and hypoglycemia). Low glucose led to a robust secretory response in a subset of AMCs, however a significant number of AMCs were glucose-insensitive. Despite this fact, these glucose-insensitive AMCs were healthy as evidenced by their robust high K+-evoked secretion, which was not significantly different than the high K+-evoked response in glucose-sensitive AMCs. Aglycemia increased the quantal frequency and mean quantal size leading to an increase in catecholamine secretion. On the other hand, hypoglycemia (3 mM glucose) increased quantal frequency and had no effect on quantal size.

I tested for the requirement of voltage-gated Ca2+ channel (VGCC) activation in the aglycemia response. The general VGCC blocker Ni2+ (2 mM) abolished the aglycemia-evoked secretory response, and moreover, low concentrations of Ni2+ (50 μM) blocked the aglycemia-evoked secretory response indicating the involvement of T-type VGCCs. The specific L-type VGCC blocker nifedipine (10 μM) also inhibited the aglycemia-evoked response, indicating that both the L-type and T-type VGCC are necessary for the secretory response during aglycemia.

I developed a fresh thin slice adrenal gland preparation to study the glucose-sensitivity of adrenal glands in slices. This limits phenotypic changes which occur in culture and maintains the integrity of the tissue. In preliminary studies using neonatal adrenal thin slices aglycemia-evoked catecholamine secretion was detected. Aglycemia increased the event frequency but had no effect on quantal size.

abstract: The 20th century introduction of antibiotics made once fatal infectious diseases readily treatable. This taken-for-granted therapy is now threatened by rising antibiotic resistance. The ability of pathogens to acquire numerous simultaneous resistance mechanisms has given rise to an alarming number of increasingly difficult to treat multi-drug resistant infections. When coupled with a sharp decline in development of novel antibiotic therapies, health practitioners today are left with limited therapeutic options. Several alternative methodologies have been employed to find novel therapeutics, including new techniques in natural product isolation and the production of semi-synthetic and synthetic antibiotics; however, there has been limited focus on targeting antibiotic resistance mechanisms directly to create synergistic therapies. We demonstrate the potential in using small molecules to target antibiotic kinases, thereby rescuing the antibiotic action of aminoglycosides and macrolides when used in combination. We conducted a thorough examination of these enzymes including: kinetic analysis; an assessment of phosphate donor specificity; and in-depth structural comparison, including a case study on the structure-function relationship of APH(4)-Ia. This analysis culminated in an intensive screening initiative of fourteen antibiotic kinases against a set of well defined protein kinase inhibitors. From this work, we have identified several inhibitors that have the potential for use in future combination therapeutics. This study illustrates the benefit of a structure-activity based approach to drug discovery, an important tool at a time when novel therapeutic strategies are required.

title: A Hybrid Thermoelectric Cooler Thermal Management System for Electronic Packaging

contributor:
Ching, Chan Y.
Mechanical Engineering

abstract: Conventional cooling techniques, such as the use of heat pipes and forced convective cooling can be inadequate for many high performance electronic chips or when the operating ambient temperature is high. In such cases, there is a need for active cooling of the chip to keep its operating temperature below the design point. Thermo-Electric coolers (TEC) provide an attractive option in such instances and have been developed and used for thermal management in electronic packaging systems. Such systems, however, can have a low overall coefficient of performance since the TEC needs to be kept on even at low heat load conditions. In this thesis a hybrid thermal management system is considered that incorporates a TEC based active path in parallel with a conventional heat pipe based passive path. A thermal resistance network model is developed for the hybrid system that takes into account the governing thermo-physical equations for the TEC. The advantage of this hybrid system is that the passive path can transport the heat from the chip at moderate thermal conditions keeping the TEC electrically off while the TEC modules can be turned on when.the conditions become adverse. A higher overall system coefficient of performance can be achieved compared to a system consisting of only TEC module(s). One important design parameter is the fraction of the total heat sink area dedicated to each path, which will depend on the rated heat dissipation from the chip, thermal resistance of the entire heat sink and the operational ambient temperature. Controlled experiments were performed to validate the hybrid thermal management model for an example case of electronic package. The experimental facility consisted of a flexible heater to simulate the chip. The heat sink in the experiments was a cooling loop and the ambient temperature was controlled by changing the temperature of the water flowing through the cooling loop. The thermal resistance of the heat sink was simulated by acrylic glass. Experiments were performed for different fraction of the heat sink area dedicated to the heat transfer paths for a range of ambient temperatures. An operating envelope was presented to compare different hybrid thermal management configurations with a heat pipe based passive system and an only TEC system. The model predictions were in good agreement with the experimental results. Parametric studies were performed to analyze the effect of different variables on the system performance. The hybrid model can be used for other thermal management systems involving TEC modules.

title: A Regression Test Selection Technique Applied to Legacy Systems

abstract:
Software testing is a necessary step in both the software production chain and during future maintenance. Testing can be performed using many different techniques. It is much easier to test a piece of software during the original development process, rather than after the system has been deployed and in use for many years. However, testing must be performed whenever software is altered. How should testing be performed on legacy software? The answer to this question is the focus of this thesis.

Regression testing is performed on software during its maintenance stage. Usually it is done after changes have been made to the software or its environment. The concept of regression testing does not assume the existence of a test suite for the software. It might be the case that test cases have to be created from the scratch. However, when software with a huge existing test suite is under consideration, then it is not always a good idea to run the whole test suite in order to perform regression testing. This might be too expensive both in time and human effort. This problem motivate the concept of regression test selection, which tells us that by using certain selection criteria it is possible to select a subset of an existing test suite and run that subset on the software instead.

Our project involves reducing the burden of regression testing for a legacy system that is built on top of the Oracle E-Business Suite and Oracle database. The changes are made through patches that are sent by Oracle. Most of the time, patches do not introduce big changes to the E-Business Suite. Also, it is likely that the legacy software application uses a relatively small portion of Oracle's Enterprise Resource Planning (ERP) system. In this case, it is crucial to be able to select a subset of the test suite for regression testing. Running the whole test suite can be very costly, and is almost always not necessary.

The approach we adopted relies on building the access dependency graph of the whole system first. An access dependency graph is a control flow graph but with fields and methods of classes as nodes. Then, after identifying which places in the Oracle E-Business Suite changed after patching, the inverse calling paths are built with changed places as starting points and functions in the customer's application as end points. Now, when affected functions have been identified, it should be possible to select a subset of the existing test suite which will exercise functions that have been directly or indirectly changed by the patch, and which will not include tests that are not impacted by the changes to the software system embodied in the patch. We also demonstrate that the selection technique proposed in this work is safe (does not miss tests that should be included). This gives us some confidence about the applicability of the algorithm.

title: THE ROLE OF dRanBPM IN THE DROSOPHILA LARVAL CNS AND ITS EFFECT ON FORAGING BEHAVIOUR

contributor:
Campos, Ana R.
Biology

subject: Biology Biology

abstract: The foraging stage of larval development is characterized by an attraction to food resources and an increased consumption of nutrients. Food attraction is partially mediated by an attunement to a light source, visible as distinct locomotor patterns that larvae exhibit in light and dark environments. Loss of the Drosophila Ran Binding Protein in the Microtubule Organizing Center (dRanBPM) leads to a disruption of locomotion in response to light, a reduction in larval feeding and larval size, and a decrease in viability. The long isoform of dRanBPM has been shown to localize to the Mushroom Body (MB) of the larval CNS, an important structure involved in learning and memory behaviours. Various neuronal markers failed to show any severe morphological abnormalities due to loss of dRanBPM gene function in the larval CNS. In addition to a decrease in food consumption, dRanBPM mutants also showed a decreased attraction to a food source. These results are supplemented by evidence that dRanBPM affects sensory modalities associated with olfaction and phototaxis. The role of the MB in larval behaviours associated with loss of dRanBPM gene function has yet to be fully elucidated. dRanBPM mutant behavioural phenotypes, such as larval response to light, have been recapitulated through MB silencing studies. My results suggest further that decreasing but not increasing excitabi Iity in the y neurons of the MB affects response to Iight and feeding behaviours.

abstract:
In 1984, the ZED-2 research reactor was used to study five (Th, Pu)O2 fuel bundles with the goal to provide both benchmark tests for future reactor code validation and experimental measurements for a possible thorium fuel cycle in CANDU. In this work, the neutronic models of these critical experiments were investigated by TSUNAMI, a sensitivity and uncertainty (S/U) analysis tool, part of the SCALE6 reactor physics package from the Oak Ridge National Laboratory.

TSUNAMI consists of different modules that are capable of calculating the values of keff and the uncertainties in keff due to uncertainties in the nuclear data. It generates energy-dependent sensitivity coefficients from which the percentage change in keff due to perturbations in nuclear data values can be determined. The calculated keff has a bias which is the difference between calculation and measurement. Several sources of uncertainties are responsible for the observed keff bias. But the most dominant and universal contributor is the uncertainties in the nuclear data. Because of the shared nature of nuclear data in all simulations, correlations among the calculated keff values exist and can be measured in terms of the correlations in the nuclear data uncertainties. TSUNAMI provides a consistent and systematic approach to examine these correlations and their effect on keff biases. It also offers an interesting application of the Generalized Linear Least Squares (GLLS) methodology which applies adjustments to the original nuclear data so that keff biases are reduced.

Using TSUNAMI, the computed keff values agree with the experimental keff up to a bias of 2.3mk or lower. It is also found that the list of top uncertainty contributors in keff is identical among the simulations, confirming a high degree of correlation in the nuclear data uncertainties. An illustrative example demonstrated the application of TSUNAMI to coolant void reactivity. In this particular simulation, the coolant density was reduced to mimic the loss of coolant condition. Positive reactivity was induced as the simulation predicted. Through S/U analysis, the uncertainty in the computed reactivity was determined in a similar fashion as the keff uncertainty. Top reactivity uncertainty contributors were also identified. Finally the GLLS procedure was explored using the coolant void example along with the experiments.

Even though the results are not conclusive on the applicability of these (Th, Pu)O2 ZED-2 benchmark experiments to future thorium CANDU reactors, they have called attention to the need for a larger number and better designs of relevant benchmark experiments. It is proposed that they should be designed to maximize the sensitivity information of thorium and plutonium in order to offer more meaningful S/U analysis and establish good confidence in the future investigation of (Th, Pu)O2 fuel in CANDU reactors.

title: An Experimental Rig and Investigation of Steam Generator Tube Loading during Main Steam Line Break

contributor:
Weaver, David S.
Mechanical Engineering

abstract: Tubes in steam generators vibrate when subjected to cross-flow of secondary side coolant, particularly in the U-bend region. Such tube vibrations result in fretting wear at tube supports, reducing the margin of safety against failure. In the event of a main steam-line- break, the superheated water In the steam generator undergoes rapid depressurisation, resulting in a high-velocity two-phase steam-water flow across the steam generator tubes. This rapid blow-down phenomenon induces potentially catastrophic transient loading that is difficult to predict. Since the tubes represent the boundary between irradiated primary side fluids (deuterium) and the secondary side coolant, tubes in CANDU steam generators that cannot withstand the transient loading will leak irradiated primary side fluid into the secondary side, which passes outside of the containment building. The objective of this experimental study is to develop a better understanding of the transient loading and its prediction, such that structural tube failures can be avoided.
