The Influence Of Eighteenth-Century British Landscape Aesthetics On Narrative And Pictorial Responses To The British North American North And West 1769-1872, I S. Maclaren
Digitized Theses
This study undertakes a consideration of a century of travel writing by Britons who explored, surveyed, traded, hunted, prospected, botanized, and established missions in the British North American North and West between 1769 and 1872. Its particular concern is how Britons employed the principles and conventions of eighteenth-century British landscape aesthetics to describe and depict northern and western terrain.;An aesthetic mode of perceiving nature, as has been argued by perceptual geographers, art historians, and literary critics, constitutes one way that a society forms it understanding of reality. For the eighteenth- and early-nineteenth-century Briton, the Sublime and the Picturesque were the …
Age-Structure And Unemployment: Some Consequences Of The Post-War Baby Boom, David Kerr Forrest
Age-Structure And Unemployment: Some Consequences Of The Post-War Baby Boom, David Kerr Forrest
Digitized Theses
The paper examines the impact of demographic changes on the rate of unemployment in Canada. The central question asked is whether the increase in the number of young people in the population during the 1970s put upward pressure on the overall unemployment-rate. It was expected to have done so because (i) a greater fraction of the labour-force would now fall within an unemployment-prone age-category, and (ii) in the absence of sufficient wage flexibility, a shift in the supply curve of a particular type of labour (defined by age) would generate unemployment in that age-group (this is the so-called cohort-crowding hypothesis). …
Food Resource Utilization By Five Species Of Benthic Feeding Fish In Passamaquoddy Bay, New Brunswick, John Stevenson Macdonald
Food Resource Utilization By Five Species Of Benthic Feeding Fish In Passamaquoddy Bay, New Brunswick, John Stevenson Macdonald
Digitized Theses
Feeding relationships of various fish species, and their relationship to the composition of the surrounding sediments, were observed for one year at two sites in the lower Bay of Fundy region. The fishes were the ocean pout (Macrozoarces americanus), winter flounder (Pseudopleuronectes americanus), plaice (Hippoglossoides platessoides), cod (Gadus morhua) and witch flounder (Glyptocephalus cynoglossus). After reducing the size of the data matrix by removing redundant variables (prey items), interspecific diet overlap and the degree to which stomach contents reflect benthic composition were assessed using discriminant functions analysis. Variables were ranked by their power to discriminate among pairwise comparisons of groups: …
Application Of Counter-Current Fluidized Cascade In Flotsam-Rich Mixtures, Edward Wing-Kee Chan
Application Of Counter-Current Fluidized Cascade In Flotsam-Rich Mixtures, Edward Wing-Kee Chan
Digitized Theses
The counter-current gas fluidized cascade is a novel pneumatic device for the separation of mixed granular solids according to density and size difference. The study presented here is restricted to the application of the cascade in flotsam-rich binary solids systems.;The purpose of this study was to investigate the effect of the density difference and size distributions of the two solids, the height and speed of the paddles, the fluidization velocity and feed and product withdrawal rates on the separation performance of the cascade. It was observed that while a significant density difference would usually result in strong segregation in the …
Theoretical And Experimental Studies In Visible Laser Spectroscopy, Akira Brian Yamashita
Theoretical And Experimental Studies In Visible Laser Spectroscopy, Akira Brian Yamashita
Digitized Theses
In this thesis, two different aspects of the interaction of radiation with molecules are studied. First, a previously-derived exact solution to the time-dependent Schroedinger equation describing the interaction between a sinusoidally-oscillating field and an N-level atomic or molecular system is used to examine the temporal and steady-state behaviour of a five-level model molecular system. Secondly, the technique of polarization labelling spectroscopy is used to study the E 0(,g)('+) state of the iodine molecule.;The behaviour of the five-level system, consisting of a ground state and four "nearly degenerate" excited states, is studied for various experimental conditions, and for single- and three-photon …
The Geochemistry And Mineralogy Of Recent Sediments Of The Niger Delta, Biodun Elijah Olorunfemi
The Geochemistry And Mineralogy Of Recent Sediments Of The Niger Delta, Biodun Elijah Olorunfemi
Digitized Theses
A study of the mineralogical and chemical composition of recent sediments of the Niger delta, Nigeria was undertaken to provide baseline geochemical data and to relate these data to soil fertility, erosion and engineering problems. The mineralogical composition shows that three areas are distinguished: (1) a large kaolinite-quartz zone; (2) restricted kaolinite-beidellite zone; and (3) a highly restricted metastable smectite zone mainly montmorillonite and nontronite. The mineralogy is interpreted as functions of stability, groundwater flow rates, permeability and sea water incursion. Type 1 occupies the dynamic central part of the delta where permeability exceeds 1 Darcy, with rainfall averaging 6.8 …
Canadian Eskimo Literature: The Development Of A Tradition, Robin Mcgrath
Canadian Eskimo Literature: The Development Of A Tradition, Robin Mcgrath
Digitized Theses
Prior to contact with European culture, Eskimos in the circumpolar world had a highly developed oral tradition. The subsequent widespread adoption of Christianity in the Arctic region resulted in nearly universal literacy among Eskimo adults, and the oral tradition almost immediately began to develop into a written one. In Canada there is now a considerable body of Inuit literature available in both Inuktitut and English, and this thesis examines how this literature developed. A brief history of European contact as it affected literacy, a consideration of the movement from the oral to written tradition, and a description of early Inuktitut …
The Emergence Of B F Skinner's Theory Of Operant Behavior: A Case Study In The History And Philosophy Of Science, Kristjan Gudmundsson
The Emergence Of B F Skinner's Theory Of Operant Behavior: A Case Study In The History And Philosophy Of Science, Kristjan Gudmundsson
Digitized Theses
This thesis is a case study in the history and philosophy of science concerned with the emergence of Skinner's theory of operant behavior. During his graduate work in experimental psychology at Harvard University during 1928-31 Skinner became committed to the reflex tradition by way of an analogical extension of the experimental problem/solutions of Sherrington and Pavlov, in the sense of Kuhn's original concept of the exemplar. The reflex tradition however, is not the monotheoretic entity Kuhn makes the paradigm out to be, but is rather a global theory in the sense of Laudan's research tradition, understood as a succession of …
Self-Perceptions And Smoking Behavior, Austin Thomas Deslauriers
Self-Perceptions And Smoking Behavior, Austin Thomas Deslauriers
Digitized Theses
In order to implement the purpose of this research, it was decided to try to identify a set of self-perceptual variables which distinguished people in terms of their smoking behavior. Smoking behavior was construed as manifesting itself across a continuum from nonsmoking to smoking. This was consistent with the self-orientation of the present research in which smoking is not viewed as a discrete behavior, separate from one's view of self. With the general aim of gathering as much information as possible from a previously unexplored area, a questionnaire was constructed which tapped four aspects of self-perception: general self-description (adjective ratings), …
The Relation Between Food Abundance And Reproductive Performance Of Tree Swallows, Terry Edwin Quinney
The Relation Between Food Abundance And Reproductive Performance Of Tree Swallows, Terry Edwin Quinney
Digitized Theses
Few field studies have examined experimentally the importance of food availability on adult activity and breeding performance in birds. I studied two populations of insectivorous Tree Swallows Tachycineta bicolor, 3 km apart, that differed primarily in the amount of food available to the breeding birds. I obtained an index of food abundance and conducted experiments involving the transfer of clutches and broods between populations. Tree Swallows showed substantial phenotypic plasticity in breeding characteristics and parental activities. My results demonstrated that food abundance during the the breeding season influenced clutch size, egg quality, nestling growth, behavior, survival to fledging and adult …
Superovulation And Infertility In Immature Rats, Elizabeth Anne Walton
Superovulation And Infertility In Immature Rats, Elizabeth Anne Walton
Digitized Theses
This study examined the possible causes of infertility in immature rats following superovulation (SOV) with pregnant mares' serum gonadotrophin (PMSG). The areas looked at included the timing of ovulation, oocyte normality, fertilization, oviductal transport, early embryo development and implantation.;SOV with a single injection of PMSG or continuous infusion of follicle-stimulating hormone (FSH) was compared and in some rats the period of action of PMSG was restricted to (TURN) 58 h by use of a specific antiserum (a/s). Pregnancy was observed in most FSH-infused rats whereas following SOV with PMSG pregnancy failed prior to day 5. Increased ovarian oestradiol secretion was …
Comparison Of Four Models For Predicting Person Reliability, Geziena Cynthia Fekken
Comparison Of Four Models For Predicting Person Reliability, Geziena Cynthia Fekken
Digitized Theses
The purpose of this research was to examine the efficacy of four models for predicting person reliability, which was defined as across-session item consistency. Two prediction models were based on item characteristics alone, namely, p-values and social desirability scale values. Two prediction models attempted to take into account both item and person characteristics. These models were based on individuals' latencies for responding to particular items and on individuals' thresholds for answering items in terms of some item characteristics. The latter model was derived from Jackson's (1968) threshold model for responding which describes the response process with reference to a threshold, …
Essays On Monetary Control, Timothy David Lane
Essays On Monetary Control, Timothy David Lane
Digitized Theses
This thesis is a set of essays addressing some issues related to the control of the money supply. Some issues considered are the appropriate instrument for monetary control (monetary base or interest rate), the time horizon over which this control should be effected, and the correct response to deviations of the money stock from its target path.;The first chapter is an introduction. The second chapter reviews the literature on two alternative rationales for money-supply targets which have quite different implications for the seriousness of departures of the money stock from its target.;Chapter Three deals with instrument instability: the argument that …
Fenestrations In The Internal Elastic Lamina Of Human Cerebral Arteries And Their Probable Role As A Factor In The Etiology Of Saccular Aneurysms, Gordon John Campbell
Fenestrations In The Internal Elastic Lamina Of Human Cerebral Arteries And Their Probable Role As A Factor In The Etiology Of Saccular Aneurysms, Gordon John Campbell
Digitized Theses
The main purpose of this investigation was to characterize the spatial geometry of the fenestrations (windows) in the internal elastic lamina (IEL) from human cerebral arteries. The IEL was isolated from the arterial wall and prepared for examination by the scanning electron microscope. A new method identified a uniform shrinkage for the IEL of only 6.9 (+OR-) 0.21 SEM %. The photomicrographs of the external surface of the IEL revealed a continuous sheet penetrated by numerous round fenestrations with smooth borders. Four geometrical characteristics based upon the diameter and the number of fenestrations in the field of view for every …
The Aerodynamic Loads On A Flat Plate Between Parallel Walls Due To Rotational Flow Disturbances, Hani Abdel-Razik Alnakeeb
The Aerodynamic Loads On A Flat Plate Between Parallel Walls Due To Rotational Flow Disturbances, Hani Abdel-Razik Alnakeeb
Digitized Theses
In the thesis the effects of rotational flow disturbances on a body placed in an inviscid, incompressible fluid stream and in particular the case of a flat plate situated midway between two parallel planes were studied. A single vortex approaching the flat plate was first considered and then expanded to simulate the effects of pseudo-turbulence on the flat plate.;The finite-element and finite-difference numerical methods were evaluated in the thesis and arguments were made in support of using the finite-difference approach rather than the finite-element approach. The fact that the finite-difference technique was used for the particular flow problems studied in …
The Role Of Individual Difference Factors In The Efficacy Of Covert Modeling And Self-Instructional Training For Fear Reduction, Terrance Michael Vallis
The Role Of Individual Difference Factors In The Efficacy Of Covert Modeling And Self-Instructional Training For Fear Reduction, Terrance Michael Vallis
Digitized Theses
This series of studies examined the role of selected individual difference factors in the efficacy of visual imagery (Covert Modeling) and verbal (Self-Instructional Training) coping skills procedures. Specifically, individual differences in imagery-verbal processes were examined. A variety of individual difference measures were employed in an attempt to understand whether previous inconsistent data were due to assessment issues. Also, these studies employed an 'Aptitude-Treatment Interaction' (ATI) design to evaluate the role of the individual difference variables. This design is more powerful than the typical median split procedure.;Study 1 focused on whether ATI effects could be found between Covert Modeling and Self-Instructional …
Parent Control And Joint Venture Success: The Case Of Mexico, Jean-Louis Francois Schaan
Parent Control And Joint Venture Success: The Case Of Mexico, Jean-Louis Francois Schaan
Digitized Theses
Managers in multinational companies face a strategic dilemma. They generally want to have full management control over their foreign subsidiaries, at a time when host governments, responding to social and economic forces in their own countries, are enforcing more and more arrangements which require sharing ownership and control.;By comparing successful and less successful joint ventures operating in Mexico, this dissertation attempts to provide empirical evidence on the relationship between parent control and joint venture success. More specifically, it examines how managers in parent companies ensure that their joint ventures meet their expectations.;The study focussed on ten joint ventures (five in …
Studies On The Structure And Origin Of The Parasporal Inclusion Of Sporulating Bacilli, James Peter Insell
Studies On The Structure And Origin Of The Parasporal Inclusion Of Sporulating Bacilli, James Peter Insell
Digitized Theses
The parasporal inclusions of B. thuringiensis subspecies kurstaki, subspecies israelensis, subspecies schwetzova, subspecies alesti, subspecies finitinus, and B. cereus subspecies medusa and subspecies lewinia were purified and analyzed by one-dimensional slab gel electrophoresis. The inclusion of each of the above subspecies was composed of different polypeptides. The protein composition of the inclusions was correlated with the sahpe, structure and toxicity of the inclusion. Four types of inclusions were formed by the seven subspecies studied. Three representative subspecies were chosen for further study.;Two strains of B. cereus and eight subspecies of B. thuringiensis were screened for the presence of plasmid DNA. …
Epistemic Decision And The Duhem Problem, Po Keung Ip
Epistemic Decision And The Duhem Problem, Po Keung Ip
Digitized Theses
The Duhem problem, as interpreted here, is concerned primarily with the ambiguity of scientific testing--falsifying experimental data can never uniquely determine the theoretical target to be falsified. By reformulating the Duhem problem within an epistemic decision framework recently proposed by Isaac Levi, it is hoped that the Duhem problem can be seen as a problem in epistemic decisions and hence can be solved decision-theoretically.;The motivations for adopting the decision-theoretic approach to scientific inquiry are discussed. Views of Popper, Carnap, Lakatos, Hempel and Levi are reviewed. The structures of practical decision and cognitive decision are critically compared. Epistemological concepts relating to …
Numerical Solution Of Three Instability Problems, Jacob Greydanus
Numerical Solution Of Three Instability Problems, Jacob Greydanus
Digitized Theses
This thesis obtains numerical solutions for three instability problems.;The first is a Rayleigh-Taylor interfacial instability problem. Numerical solutions are obtained using a co-ordinate transformation technique and two approaches are tested for use in solving the field equation: (a) transformation and extremization of the variational integral, and (b) transformation of the differential equation itself. The latter is also tested with the use of higher order finite difference formulae. Solutions are generated with the most suitable method and compared with the predictions of Nayfeh's non-linear perturbation theory. While there is good qualitative agreement it is found that the quantitative agreement degrades with …
The Boundary Definition Problem: Statistical And Geometric Approaches, Richard Averack
The Boundary Definition Problem: Statistical And Geometric Approaches, Richard Averack
Digitized Theses
The boundary definition problem involves the selection of appropriate criteria and methods for portraying boundaries of geographical distributions. Although this is a very important consideration in many academic fields, particularly geography, biology and sociology, apparently very little attention has been devoted to it in the literature. Boundaries are, as a rule, rather carelessly and subjectively drawn.;Various approaches to bounding discrete point distributions are explored in this thesis. These approaches fall into two categories based on the amount of information available about the distribution. In some caes, only locations are known and a boundary must be defined based soley on the …
Keats And The "Service Of The Time Being", Joanne Lorna Buckley
Keats And The "Service Of The Time Being", Joanne Lorna Buckley
Digitized Theses
This dissertation is an exploration of Keats's poems and letters with an eye to discovering his attitude toward the viability of poetry in a post-Lockean universe. Keats's concern with the subjective limitations of imagination in the face of scientific advancement in his time and its effects on his poetry are thus its subject.;The Echo and Narcissus myth, as it relates to the reflexive imagery in Keats's work, is used as a paradigm of the Lockean split between reflection and sensation and its relation to the poetic process. Certain motifs related to Keats's reflexive imagery are then examined, including the motifs …
Towards An Optimal Level Of Participation Of The Intermediary In The User-System Interface Of Bibliographic Online Search Services, Gilles H. Deschatelets
Towards An Optimal Level Of Participation Of The Intermediary In The User-System Interface Of Bibliographic Online Search Services, Gilles H. Deschatelets
Digitized Theses
The present research project focuses on the user/system interface of on-line bibliographic search services and more specifically on the role of the human intermediary in the context of on-line searching. A quasi-experimental study was designed with 34 end-users and 22 intermediaries who performed 102 online searches in 6 different organizations (3 academic and 3 special libraries). Each end-user was given a one-day training session and then prepared three different search questions. An on-line search was performed for each question: one direct search (the end-user alone), one delegated search (the intermediary alone) and one combined search (the end-user and intermediary together).;Numerous …
Social Vision And Individual Learning In Arnold Bennett's Five Towns Fiction, Douglas William Malcolm
Social Vision And Individual Learning In Arnold Bennett's Five Towns Fiction, Douglas William Malcolm
Digitized Theses
Arnold Bennett's reputation has been hampered by the disfavour that he incurred among the leading modernists and the critical tendency to treat realism as an attempt to achieve social mimesis. If realism is regarded as a mode of fiction, Bennett's Five Towns books can be seen as an endeavour to formulate a coherent social vision rather than as a reproduction of the Staffordshire Potteries. In Anna of the Five Towns, The Old Wives' Tale and Clayhanger, the best of the Five Towns works, the characters' environment displays an increasing propensity to divide into personal and social worlds, both of which …
Client Strategies In The Management Of The Audit Process, Jean Nollet
Client Strategies In The Management Of The Audit Process, Jean Nollet
Digitized Theses
An audit is the process used by independent professional accountants to gather evidence to express an opinion on the financial statements of an entity, usually a company. Even though audits are customarily done for shareholders, they are often conducted for third parties such as lenders and potential investors. Companies that require audited financial statements need annually to purchase audit services.;A substantial amount of research has focused on the way auditors perform their tasks but this thesis focuses on the way clients manage the audit process. The audit process consists of work which is done by the auditors, the client and …
The Logic Of Fundamental Processes: Nonmeasurable Sets And Quantum Mechanics, Itamar Pitowsky
The Logic Of Fundamental Processes: Nonmeasurable Sets And Quantum Mechanics, Itamar Pitowsky
Digitized Theses
Quantum theory has played a significant role in modern philosophy both as a source of metaphysical ideas and as an important example of a 'scientific revolution'. In spite of the sixty or so years that have elapsed since its invention, a long lasting controversy concerning the interpretation and meaning of quantum theory prevails. Almost all authors, however, seem to agree on one major point, namely, that there could be no interpretation of this theory which is both realistic and local.;The purpose of this thesis is to demonstrate that this premiss is false and that a realistic, local and deterministic interpretation …
Across-Wind Response Of Slender Structures Of Circular Cross-Section To Atmospheric Turbulence, Roger Indranath Basu
Across-Wind Response Of Slender Structures Of Circular Cross-Section To Atmospheric Turbulence, Roger Indranath Basu
Digitized Theses
A mathematical model which yields estimates of across-wind response is presented. Fluctuating forces from three sources are identified and modeled. They are forces due to vortex shedding, forces induced by the lateral component of turbulence and forces induced by motion. The motion dependent force, which in reality is a complex flow-structure interaction phenomenon, is incorporated in the model through a simple device. The model is semi-empirical in construction, and relies on the results from laboratory-scale experiments for the empirical component.;The reliability of the predictions depends not only on the fidelity of the mathematical model but also on the quality of …
Mechanisms Of Reactions Of Alkenesulfonyl And 2-Substituted Ethanesulfonyl Chlorides, John Henry Hillhouse
Mechanisms Of Reactions Of Alkenesulfonyl And 2-Substituted Ethanesulfonyl Chlorides, John Henry Hillhouse
Digitized Theses
This thesis describes the mechanisms of the reactions of some simple alkenesulfonyl chlorides and 2-substituted ethanesulfonyl chlorides with tertiary amine bases in aqueous and organic media.;Chapter 1 describes the reactions of ethenesulfonyl chloride and trans-1-propene-1-sulfonyl chloride with water in the presence and absence of substituted pyridines. The former reactions are concluded to proceed by S(,N)2' attack of the pyridine based on the sulfonyl chloride to generate ultimately a pyridine betaine and the pyridinium alkenesulfonate. The formation of the alkenesulfonate anion from the alkenesulfonyl chloride by reaction of the pyridine base corresponds to the first well-established example of a vinylogous nucleophilic …
Adsorption Of Cations At The Sulphide/Water Interface, Gilles Elziar Jean
Adsorption Of Cations At The Sulphide/Water Interface, Gilles Elziar Jean
Digitized Theses
The adsorption of aqueous metal ions on various sulphide minerals was studied as a function of time, pH, surface composition and chemical speciation.;In the first part of this work (Chap. 3) the reaction between various types of gold solutions and several minerals was followed using XPS and SEM. Gold from chloro auric solutions was reduced quickly from Au(III) to Au(O) by every sulphide mineral studied. SEM showed the gold to be unevenly distributed on the surface in the form of agglomerates. Oxide minerals did not reduce gold to any great extent. The gold was shown to adsorb on the sulphide …
Dynamics Of The Eukaryotic Cell Surface - Lectin Binding To Model Membranes, Nika Victoria Ketis
Dynamics Of The Eukaryotic Cell Surface - Lectin Binding To Model Membranes, Nika Victoria Ketis
Digitized Theses
Transmembrane glycoproteins, glycophorin and the Concanavalin A receptor, were assembled into large multilamellar liposomes. Lectin binding to these simple model membranes was positive-cooperative. The high affinity lectin binding to liposomes was influenced by the presence of unrelated macromolecules (serum albumin and Dextran T-500) at the membrane surface. Since under appropriate conditions the model membrane system appeared to accurately mimic the positive-cooperative behavior observed for binding of various lectins to intact cells, it is suggested that the source of the high affinity binding and its positive-cooperative nature in the described system is the lectin-induced, surface coat dependent 'chelate' or 'avidity' effect. …
