abstract:
The emergence of pharmaceuticals in wastewater effluent is of increasing concern to aquatic organisms. Cytochrome P450s (CYPs) are important pharmaceutical and xenobiotic-metabolizing proteins, and their functions are well studied and understood in mammals. However, studies on CYP function and modulation in non-mammalian vertebrate systems are much less defined, and function is often inferred from mammalian data, assuming similar function across vertebrate taxa. In this study, we investigate in vivo induction and in vitro metabolism and inhibition of CYPs in fish liver microsomes.

In this thesis, a number of fluorometric CYP-catalyzed assays and fluoxetine, a model selective serotonin reuptake inhibitor (SSRI) , have been used to assess CYP mediated metabolism in fish. Overall, we raise questions about extrapolating known mammalian data to fish CYP function. Fluoxetine, a CYP2D6 substrate in humans, was not metabolized well in fish liver. These data suggest that perhaps fish produce a fluoxetine metabolite that is not produced by mammals. We investigate the basal metabolism and induction potential for hepatic CYPs in two fish species, rainbow trout (Oncorhynchus mykiss) and killifish (Fundulus heteroclitus). Species differences were found in the baseline metabolism of these substrates. Treatment with known mammalian CYP inducers, dexamethasone (DEX) , pregnenolone-16α-carbonitrile (PCN) , and rifampicin (RIP) did not cause broad, measurable CYP induction in either fish species. β-naphthoflavone (BNF) , a prototypical CYPIA inducer, showed significantly induced activity across many substrates, providing evidence that BNF induces more broadly than expected. We also assess the inhibition potential of potent inhibitors of important drug metabolizing CYPs in mammals: fluoxetine, ciprofloxacin, gemfibrozil and erythromycin. These compounds produce significant inhibition over most substrates tested, and are not substrate-selective as would be predicted by their inhibitions in mammals.

The experiments carried out within this thesis add to our knowledge of functional characterization of CYP induction, inhibition and metabolic activity in fish. Using a comparative approach, a number of fish species were tested for in vitro catalytic function of these contaminant-metabolizing proteins and provide evidence that fish CYPs respond differently to inducing and inhibitory compounds compared to mammals. Extrapolation across taxa should be carefully considered before assuming similar function.

abstract: Resolving the wide range of spatial scales simultaneously present in the formation of stars and star clusters is a challenge for numerical simulations. Methods such as adaptive hydrodynamics codes must be used in many gasdynamical simulations where gravity is also present, and constructs known as "sinks" are commonly used to avoid the computational expense of directly simulating the dense regions within protostars. Despite being essential to investigations of star formation over long timescales, numerics can often play an undesired role in the behaviour of these point-mass accretors, causing artificial accretion. In this thesis, the use of sink particles as models of protostars is investigated using the Gasoline N-body + smoothed particle hydrodynamics code. Motivated by observations of disks and accretion rates onto protostars, physical viscosity using the a-parametrization was implemented. Tests of both spherical and rotating protostellar accretion were performed. In spite of their importance to star formation) previously presented rotating tests are subject to several numerical problems; efforts were made in this work to simulate a three-dimensional viscous accretion disk where such issues were identified and minimized. Simulations were performed for varying strengths of viscosity and sink radius, as well as with inner boundary conditions known as "sinking" particles. Angular momentum transport was present and behaved physically in all cases with α > 0, and the average radial velocities and mass-accretion rates in the disks matched finite-difference estimates of corresponding analytic expressions.

abstract:
Molecular imaging is an exciting and relatively new technology that has found widespread use in the diagnosis and observation of various diseases. More recently, molecular imaging has penetrated areas such as drug development in order to facilitate the observation and analysis of the effects of newly developed drugs. The amounts of data in drug development experiments may be very large due to the fact that they contain both spatial and temporal information of medical images. Imaging techniques can facilitate the analysis of large amounts of data by automating information extraction and providing meaningful results.

The focus of the project concerning this thesis is to create a emporal and spatial atlas of an animal by utilizing and integrating data from images of different modalities. More specifically, the application treated in the thesis makes use of ventilation and perfusion data from CT and SPECT scans in order to aid in the observation of the effects of newly developed drugs in the treatment of lung diseases. This thesis describes the segmentation and registration techniques used in detail and how these were utilized to align and combine ventilation and perfusion data from both CT and SPECT scans.

abstract:
This thesis provides a Fully Polynomial Time Approximation Scheme (FPTAS) for the minimum total weighted tardiness (TWT) problem with a constant number ofdistinct due dates.

Given a sequence ofjobs on a single machine, each with a weight, processing time, and a due date, the tardiness of a job is the amount of time that its completion time goes beyond its due date. The TWT problem is to find a schedule of the given jobs such that the total weighted tardiness is minimized. This problem is NP-hard even when the number of distinct due dates is fixed. In this thesis, we present a dynamic programming algorithm for the TWT problem with a constant number of distinct due dates first and then adopt a rounding scheme to obtain an FPTAS.

Three major points that we make in this algoritlun are: we observe a series of structural properties of optimal schedules so that we shrink the state space of the DP; we make use of preemption (i.e. allowing the processing of a job to be interrupted and restarted later) for the design of the DP; the rounding scheme that we adopt guarantees that a factor 1+ ℇ of the optimal solution is generated and the algorithm runs within a polynomial time of the problem size.

abstract: A series of experiments investigated the ingestion of an acaloric diet (composed mainly of vaseline and methyl cellulose) by rats. While animals on an ad-lib feeding schedule seemed able to regulate caloric intake adequately in the presence of this diet, animals on a 3 hr/day schedule did not. Although ingestion of this diet resulted in retarded weight gain, they did not learn to avoid ingesting it. However, the data indicate that they did form an aversion to a nutritionally adequate diet presented in conjunction with the acaloric diet. This failure to associate the acaloric diet with the consequences of its ingestion was explained in terms of "learned safety".

abstract:
The purpose of this project was to study the failure mechanisms of carbide tools in turning operations due to fracture of the cutting edge. The study consisted of a combination of turning tests, examination of fracture surfaces and an analysis of the stresses in the tool as produced by the cutting force. Thermal stresses are so far not considered. It is concluded that chipping is a ductile failure due to high shear stresses at the cutting edge and breakage is brittle fracture originating at the rake face at a local maximum of tensile stress.

For the finite element stress analysis a new method of successively refining mesh while diminishing the analysed area is introduced which is rather effective and economical in that all computation except for the final field is done only once for various loading cases.

abstract:
Dynamic absorbers, including the tuned mass damper (TMD) and the tuned liquid damper (TLD) , have been widely used in buildings to attenuate dynamic response. As the complexity of buildings increases, their response may become susceptible to torsional motion. The induced torsional motion can be suppressed by utilizing TMDs or TLDs. As such, the performance of different absorber arrangements are important for torsionally coupled structures. Also, a rapid design tool to reduce the computational effort for the design of the absorbers optimal parameters in torsionally coupled system is essential.

In this study, the performance of different TMD/TLD configurations under both random and harmonic excitation are studied and evaluated. The effectiveness of the absorber configurations considered is accessed by the response reduction factor, which is defined as the ratio of the response of structure equipped with absorber(s) to the response of structure without absorber(s). Also, a preliminary design tool to determine optimal TMD parameters is developed by introducing the concept of a generalized structure-TMD system.

abstract:
The single machine total weighted tardiness with release dates problem is known to be strongly NP-hard. With a new lower bounding scheme and a new upper bounding scheme, we get an efficient branch and bound algorithm. In the paper, we first introduce the history of the problem and its computational complexity. Second, the lower bounding schemes and the upper bounding schemes are described in detail. We also present all the dominance rules used in the branch and bound algorithm to solve the problem.

In the dominance rules part, we describe the labeling scheme and suggest a data structure for a dominance rule.

Finally, we implement the branch and bound algorithm in C++ for the problem with all the techniques introduced above. We present numerical results produced by the program. Using the same instance generating scheme and the test instances from Dr. Jouglet, our results show that this branch and bound method outperforms the previous approaches specialized for the problem.

Mascher, Peter

subject:

abstract:
Formation of defects in ceramics BaA1/3Nb2/3O3 (where A=Mg, Co or Zn) suitable for microwave applications was analyzed by using positron annihilation spectroscopy and X-ray diffraction techniques. The dependence of the microwave properties of perovskite ceramics on the defect structure of ANb2O6 (A = Mg, Co or Zn ) that was used as a precursor during the sintering process prompted us to conduct positron analysis of ANb2O6 columbites as well.

Positron lifetime experiments revealed only one defect type - grain boundaries- and demonstrated that the lifetime component originating from the annihilation in defects depends on the size of the grains contained in the materials. For perovskite samples where the grain sizes are smaller than those of columbite materials, the intensity of the defects' component is larger and varies within 28-40%. Results of coincidence Doppler broadening measurements confirmed the presence of only one type of defect in both materials, i.e. grain boundaries.

Theoretical calculations for the ANb2O6 columbite system resulted in bulk lifetimes of τb = 177, 176, and 172psec, respectively for magnesium, zinc and cobalt columbites and are in agreement with experimental values. The presence of second phases in nonstoichiometric A1+xNb2O6 (A=Mg, Co, or Zn) columbites did not change the bulk lifetimes of the columbite material because of the small difference in bulk lifetimes of the host material and impurities.

Ordering in perovskite type materials that influences the microwave properties in ceramics also changes the positron characteristics of perovskites. Theoretical simulations demonstrated that for the disordered cubic phase, τb ≈ 190 psec and for the completely ordered hexagonal phase, τb ≈ 240 psec. The bulk lifetime of the final perovskite material greatly depends on the presence of the second phases (Ba-rich and, possibly, Co-rich) as well as on the fractional part of the hexagonal phase. The influence of additional phases on rb is more significant than that of the "disorderedordered" transition and can be used to monitor changes in the concentration of the former ones.

title: Fluorous-Phase Purification of ⁹⁹ᵐTc Radiopharmaceuticals

contributor:
Valliant, John F.

abstract:
To produce Tc-based radiopharmaceuticals in high effective specific activity the excess precursor ligand must be removed. A new and convenient solid-phase ligand capture method of a resin-bound Cu chelate was recently developed to remove unlabeled ligand.[1] Herein, the impact ofsize on the purification was evaluated using three welldefined resin sizes and a model chelate system, where the average capture efficiency was 89.1 ± 3.3% and loss due to non-specific binding was 23.4 ± 1.6%.

A complementary solution-phase strategy was developed employing fluorous chemistry to remove unlabeled chelate-derivatives with less loss of product. The novel fluorous analog to the solid-phase copper chelate was synthesized in three steps (70% overall yield). Using the same model Tc(I) chelate, >99% ofthe ligand was captured by the fluorous ligand capture (FLC) method and the extent of non-specific binding was 65% lower than the solid-phase equivalent. A peptide conjugate was then used to further test the general utility ofthe FLC method with comparable ligand removal (95.1 ±0.8%) and non-specific binding (12.1 ± 1.2%).

Attempts were made to automate the FLC method using a microfluidic device with no detrimental effect to either the radiochemical yield (4.15 ± 1.0% non-specific binding) or the efficiency of ligand capture (99.74 ± 0.04%). A second strategy involved preloading the FLC agent onto fluorous silica and capturing the excess ligand (99.85 ± 0.02%) and peptide (95± 1%) as the radiolabeling mixture was washed over the cartridge with 2.25 ± 0.55% and 33.3 ± 3.2% product lost, respectively. This approach can now be incorporated into a new generation of instant kits or an integrated microfluidic preparation of molecular imaging probes in high effective specific activity.

abstract:
The objective of this thesis is to validate the results of the Integrated Model of Urban LAnd use and Transportation for Environmental analysis (IMULATE), as well as the Integrated Model for Population Aging Consequences on Transportation (IMPACT) in the Census Metropolitan Area (CMA) of Hamilton, Ontario. The land use/demographic modules of these two models are validated using observed data from Statistics Canada, while data from the Transportation Tomorrow Survey (TTS) and the City of Hamilton are used to validate the transportation modules. Statistical, graphical and GIS visualization techniques are incorporated into this validation.

This thesis illustrates some sub-modules in IMULATE and IMPACT can work very well, while the predictive ability of others is not as good. IMULATE considers more factors to simulate land use development. It generates accurate simulations of household dynamic using observed data as exogenous input. We used the "fmal demands" for economic sectors as the exogenous input to estimate the employment's distribution. After recalculating the "fmal demands" in its employment location model, the generated employment is also found to be close to the observed value. However, we found that its transportation module was not able to produce accurate predictions of inter-zonal trips and traffic flows over the Hamilton's road network.

IMPACT can predict the growth of population by gender and age with good accuracy. The simulation results for males are better than females. The inter-zonal trips generated by IMPACT are found to be much closer to the observed value than the inter-zonal trips generated by IMULATE. However, we found that the simulated trips have lower dispersion across the city than normally observed.

abstract: This content analysis focuses on the contributing factors, processes, and contexts associated with women's decisions to divorce. In reviewing both quantitative and qualitative published articles between the timeframe of 1965 - 2009, themes were extracted from research that spoke to women's reasons to end their marriages. A feminist theoretical perspective was employed as the lens through which the articles were reviewed and informed the final findings. These findings were grouped into three themes: factors, process and decision-making, and context. While these themes were presented separately, the author also notes that they are necessarily intertwined due to the complexity connected to women's decision to divorce.

contributor:
Campos, Ana R.

Biology

subject: Biology Biology

abstract: Multiple Endocrine Neoplasia Type 1 (MEN1) is an inherited cancer syndrome characterized by tumour formation in two or more endocrine tissues. Tumours arise due to a biallelic loss of the MEN1 tumour suppressor gene, consistent with the "two hit" loss of function, in which the first "hit" occurs in the germline and the second in somatic cells. MEN1 encodes a 67kDa protein, menin, which functions in a variety of cellular processes including transcription regulation, cell cycle control and genome stability. The Drosophila melanogaster homolog of menin is an 83kDa protein sharing many of the amino acids that routinely exhibit mutations in MEN1 patients. To identify novel menininteracting proteins, a mass spectrum analysis was performed and Atu was identified. Atu (dLeo1) is the Drosophila melanogaster homolog of Leo1 , a member of the RNA Polymerase II associated factor (PAF) complex. PAF functions as a platform in transcription elongation, recruiting proteins to RNA Polymerase II facilitating such processes as histone modification, 3' end formation and mRNA surveillance. Studies were undertaken to verify the interaction between menin and dLeo1 in the Drosophila melanogaster model system, and determine the role of the interaction in maintaining genome stability in response to stress. The menin-dLeo1 interaction was confirmed, observed following non-genotoxic stress. dLeo1 and dPaf1 , and additional member of PAF, were in turn found to play a role in maintaining genome stability. Loss of dLeo1 in particular results in increased genome instability even under physiological conditions. Thus a novel menin-interacting protein was identified, which in turn will contribute to the understanding of menin as a tumour suppressor.

abstract: Ganglosidoses are a group of fatal neurological disorders which primarily affect children. Pathologically, these disorders need more characterization. The recent development of mouse models of these diseases makes it possible to identify progressive pathological changes within the CNS at the molecular level. Tay Sachs disease is a lysosomal storage disorder characterized by accumulation of GM2 Ganglioside. Targeted Knockout of β-hexosaminidase A (hex a) was generated as a mouse model of Tay Sachs disease; however, the mouse showed little clinical phenotype. The molecular mechanism which allows the hexa-/- mouse to escape the disease involves a metabolic bypass facilitated by lysosomal Sialidase (neu l). In this study we hypothesize that the reason humans have the infantile Tay-Sachs whereas mice do not, is a difference in specificity between human and mouse sialidases. This specificity difference makes the human sialidase unable to hydrolyze GM2 to GA2, which leads to the accumulation of GM2 in neurons and consequently a resulting Tay-Sachs phenotype. In this project, a transgenic mouse expressing human Sialidase under the control of the mouse neul promoter was generated. Then a crossing of this mouse with hexa-/- mouse was done to generate a Tay Sachs mouse expressing human Sialidase. This double transgenic mouse was characterized phenotypically, biochemically and histologically. I found that the double transgenic mice are small in size, have hind limbs spasticity, peculiar posture with Kyphosis, and visual impairments; and around three months of age, which is very early comparing to Tay-Sachs late-onset animal model. Moreover the animals showed muscle weakness and clasping of their hind limbs, and they depicted weird behavior presented in vigorous combing of their faces while standing on their hind limbs and tails. However, these results indicate no significant difference between hexa-/- and the double transgenic (hexa-/-KI+) mice in gangliosides catabolic pathway.

abstract: Classification or Categorization is a text mining technique in which the given text documents are classified into specified categories. There are several techniques for classifying messages, ranging from simple K Nearest Neighbours to complicated Support Vector Machines. These classifiers have proven to be effective in cases where the documents in each category do not have a great deal of overlap with other documents. Designing a classifier that is effective in environments where there is no way to avoid this overlap, like em ails, text messages, or user opinions and comments, has remained a continuing challenge. This work is a proposal for a system that classifies such documents based on their content so they can be sorted by semantic significance. This has several applications in the real world, like triaging patient messages to physicians in the healthcare field or sorting user opinions on a product webpage. We have combined and tailored different classifiers to build a high performance classifier that supports this type of classification. The system has been tested and proven to have good performance with real-world user messages that were exchanged between patients and physicians during a hypertension prevention study.

subject: Religion Religion

abstract:
Pacifism, though by no means the whole, is central to the thought of the Catholic Worker movement. This work is an attempt to explicate that position; to describe its development, the history of tis expression, in word and act, and to define its major emphases.

Founded in 1933, the Cathollc Worker was pacifist from its inception. That pacifism was, however, ambiguous and inchoate. Only under the pressure of larger events -- violence in the labor movement, the Spanish civil war, and finally World War II -- did the pacifism of the movement become more sharply defined. The Worker emerged as a clear and powerful voice for Christian pacifism and the focus for Catholic pacifism.

The key figure in the definition and expression of the pacifism of the Worker has been Dorothy Day who, with Peter Maurin, founded the movement. Though several other Workers played important roles, -- notably Father John Hugo D H.obert Ludlow, and Ammon Hennacy -- it is Dorothy Day who is largely responsible for Catholic Worker pacifism.

That the pacifism of the Worker is primarily religious, is undeniable. Though there has been talk of the just war tradition, the pacifism of the movement is rooted in the Gospel, in the teaching and example of Jesus. The key themes in the religious pacifism of the Catholic Worker ares 1) the teaching of the Sermon on the Mount, 2) the contrast between the works of mercy and the works of war, and 3) the idea of war as a violation of the Mystical Body of Christ.

title: Noise Sources Characterization of Automotive HVAC Systems

contributor:
Ziada, Samir

abstract: The noise sources and mechanisms of the front and rear HVAC systems of an automotive are characterized experimentally. The front system has three main outlet ducts equipped with louvers and operates in two modes of bypass and recirculation. The inlet and outlet sides of the rear system are both located in the cabin; hence, it always works only on the recirculation mode. The outlet duct of the rear system is covered by a ten-hole curved plate which is found to be a strong source of noise. Both systems are tested at the highest possible flow rate, as it is the most annoying condition of noise generation. The noise coming out of each duct of the front and rear systems and their fan units are measured separately. Since the fan is an important part of the systems, it is studied at different speeds with more details. In order to compare the effect of the noise generated by the fan section with the noise produced by the complete system, the impeller is replaced with a speaker generating an overall sound level similar to the fan noise. Under this condition, the flow noise due to the evaporator core, distributive ducts and louvers are cancelled. It is concluded that at low frequencies the duct flow-noise is dominant. At high frequencies, the effects of both duct flow-noise and fan noise are impor1ant. To find out how the combination of the outgoing sound from the vents and fans inlet affect on the driver and passengers, some measurements are carried out inside the cabin of the automobile.

abstract:
Although semiconductor optical waveguides are quite mature in industry productions, fabrication of high quality lithium niobate (LiNb03) waveguides has always been a challenging topic over the past decades. Intense studies have been done, and various kinds of fabrication methods have been invented, however, existing technologies still cannot provide a satisfyng solution with both excellent performances and easy processing. Traditional ion doped optical waveguides have poor light confinement, while the newly emerged etching and precise machining techniques are still under developing. Searching for new fabrication methods for LiNbO3 waveguide devices is a meaningful pursuit of both academic and practical value.

In this study, a novel fabrication technique for LiNbO3 waveguides has been proposed and realized. Through the combination of proton-exchange and precise diamond blade dicing, the annealed proton-exchanged (APE) LiNbO3 ridge waveguides with low propagation loss and single transmission mode have been fabricated for both 1550 nm and 1064 nm wavelengths. The results have shown good agreements with theoretical simulation. Based on the obtained data, a nonlinear second harmonic generation (SHG) wavelength converter has been fabricated using the APE ridge waveguide built on periodically polled MgO:LiNbO3 (PPMgLN) substrate. Test results have shown remarkable improvements comparing with traditional waveguide structures.

Although there are remaining problems need to be solved, the fabricated waveguides have demonstrated great potentials for various optical applications. Based on this platform, mid-infrared generation by difference frequency generation (DFG), compact blue laser via SHG, high-speed optical modulators and many other useful devices can be built. Not all of them have been fully exploited yet.

abstract:
In modern wireless communication technology, designing low power, high frequency transceivers while exhibiting low noise is still one of the challenging topics in RF systems. Compared to other technologies, CMOS VCO has a poorer performance at phase noise measurements. Therefore, improving phase noise becomes a very important issue in designing a high quality YCO.

This work describes and compares the available models to realize low phase noise oscillators. On this basis, the possible criteria for reducing phase noise are discussed.

In this thesis, we explore phase noise fluctuations at the offset range of 10kHz to lOOK Hz for six 2.4 GHz LC-tuned YCOs, fabricated in O.18μm standard mixed-signal CMOS process. We compare the phase noise performance of all six circuits and draw conclusions about reducing phase noise.

The measurement results show that the Q factor of the inductor has the most significant effect on reducing phase noise fluctuations. The next important parameter is the capacitor. The resistors in the VCO do not affect phase noise fluctuations.

title: Applications of Low Density Graph Codes in Two Source Coding Problems

contributor:
Chen, Jun
Electrical and Computer Engineering

abstract: In this thesis, we present the applications of low density graph codes in two different types of source coding problems. First, we consider asynchronous Slepian-Wolf coding where the two encoders may not have completely accurate timing information to synchronize their individual block code boundaries, and propose LDPC design in this scenario. A new information-theoretic coding scheme based on source splitting is provided, which can achieve the entire asynchronous Slepian-Wolf rate region. Unlike existing methods based on source splitting, the proposed scheme does not require common randomness at the encoder and the decoder, or the construction of superletter from several individual symbols. We then design LDPC codes based on this new scheme, by applying the recently discovered source-channel code correspondence. Second, we consider the lossy source coding problem. In contrast with most prior work that has focused exclusively on the binary uniformly distributed source, we address the problem of lossy coding for sources with arbitrary alphabets and distributions. Built upon the idea of approximating the optimal output distribution indicated by the rate-distortion theory with a uniform distribution over a larger alphabet, we propose a multilevel coding scheme using LDGM codes that can approach the rate-distortion limit for a general source. Experimental results validate the effectiveness of both proposed methods.

abstract:
By studying signatures of life within extreme environments on Earth we better understand signatures of life that may be found within the geologic record on Earth as well as elsewhere in the universe. This thesis research utilized phospholipid fatty acid analysis (PLFA) in combination with carbon isotopic analysis (δ13C) to understand microbial carbon cycling and biosignatures within two Mars analogue environments.

The Golden Deposit was an acid sulfate environment that was an analogue to the acid-sulfate conditions present on early Mars. Mixing of inflowing surface water and upwelling acidic groundwater on the deposit caused variations in water chemistry. Such variations resulted in differences in the microbial communities and carbon isotopic compositions within the Golden Deposit. The most acidic groundwater seep on the deposit had a distinct geochemistry, which selected for a unique microbial community and distinct carbon isotopic signatures. Variations detected within the small spatial area of the Golden Deposit indicated that biosignatures preserved on Mars might be highly variable making the unambiguous identification of past life on the planet more difficult.

Three saline lakes of the Cariboo Plateau were used for this study and were analogues to environmental conditions present on early Earth as well as the alkaline, evaporitic conditions present on early Mars. All three lakes contained benthic microbial mat communities dominated by cyanobacteria. Photosynthetic influences by cyanobacteria resulted in an isotopic enrichment of the DIC pool. Enriched lake DIC values were preserved in precipitated carbonates (δ13Ccarb) and the ∆13CDIC-TOC(avg) was similarly preserved in ∆13Ccarb-TOC values and were biosignatures of photosynthetic activity. The preservation of these biosignatures suggested that concentrations of CO2 on early Earth did not necessarily exceed modern levels and that measuring the carbon isotopic compositions of carbon pools within saline, carbonate-rich deposits on Mars could lead to the identification of past life on the planet.

abstract: Until recently, musicology has overlooked the role of the body in musical understanding, preferring to think of music as a matter of the mind. However, musicologists such as David Lidov, Robert Walser, Susan McClary, and Suzanne Cusick have discussed the mind/body split which exists in musicology at great length and have suggested several solutions to the problem. And Peter Kivy, however, has invoked the body by suggesting that the shape of the musical line is the same as the shape of a human body when expressing an emotion. I was intrigued by Kivy's ideas and started searching for a general theory of understanding which involved the role of the body. This search led me to the theories of George Lakoff and Mark Johnson. Lakoff and Johnson suggest that the body is the essence of human understanding. They propose that we understand our world through metaphorical projections of our physical relationship to it. After an indepth look at music and emotions as separate entities, it will be shown that music is not a metaphor for emotions, in the traditional sense, but that both music and emotions are understood through the same recurring physical body-patterns. Using the theories of Lakoff and Johnson as a model, an analysis of the music of the fIlm Glory will be undertaken. This analysis is designed to demonstrate how music can be expressive of several emotions including sadness, happiness, love, and pride.

title: Post-Fire Recovery Sequence Of Black Spruce-Lichen Woodland in the Northwest Territories

contributor:
Kershaw, K.A.
Biology

subject: Biology Biology

abstract: Tree ring analyses have been used for determining the time since the most recent fire in several areas of burned black spruce-lichen woodland on drumlins in the Northwest Territories. The vegetation on these burns has been described in detail. Analysis of the data by principal component analysis and regression analysis shows that recovery of the ground vegetation after burning follows a general sequence. Topographic factors do not appear to be of much importance. The moss Polytrichum piliferum is very abundant on burns which are less than 25 years of age. For the next 100 years the ground is almost completely covered by lichens, with Stereocaulon paschale dominating the final stages of this lichen phase. After about 150 years, the abundance of S. paschale declines rapidly and is replaced by mosses and vascular plants. This change in species composition with time is accompanied by increases in the depth of organic matter and a slow development of the spruce canopy. Control of this recovery sequence by microclimatic variables is discussed. In addition, the sequence is compared to recovery sequences which have been established for other conifer regions of Canada.

title: The Low Frequency Superiority Effect in Recognition Memory

contributor:
Levy, Betty Ann
Psychology

subject: Psychology Psychology

abstract: Two explanations for the low-frequency superiority effect in recognition memory are described and a third, distractor-type hypothesis is developed. The distractor-type hypothesis proposes that Ss have a preference for abstracting semantic features from high-frequency words and acoustic features from low-frequency words. It suggests that low-frequency superiority is a result of semantic interference with high-frequency words combined with a lack of acoustic interference with low-frequency wods. The results of three experiments which support this hypothesis are required. Experiments I and II showed that more acoustic than semantic-type errors are made with low-frequency words and more semantic than acoustic-type errors are made with high-frequency words in the recognition memory paradigm. Experiments III of this series examined the relationship of the distractor type and distractor frequency variables.

title: The Religious Identity of College Students and the Holding Power of Church Denominations

contributor:
Mol, Hans
Religious Sciences

subject: Religion Religion

abstract:
This dissertation serves the purpose of contributing to the sociological understanding of religion by applying the identity theory of religion to religious denominations. Hans Mol's integration/differentiation dialectic serves as a heuristic device to examine reasons for college students' decisions to leave or remain in their familial denominations. Individuals form an identification with a religious denomination. The factors that influence the identity building process are mostly connected with the meaning and belonging dimensions of religion. The factors that diminish or inhibit the identity building process are associated with individualism, increased intellectual sophistication, autonomy, religious pluralism and secularization.

In order to test the theory with empirical evidence, a questionnaire was administered to 600 college students at State University College at Buffalo. Factor analysis divided some of the questions into clusters of meaning and belonging statements. Students were grouped into categories of committed, participating, nominal and separated members of their denominations. The committed members (those who pray and attend church frequently, and say that belief in God and religion plays a dominant part in their lives) responded more favorably to the meaning over the belonging questions. Students in the nominal membership category were more likely to respond favorably to the belonging questions, than to the meaning questions.

Part of the thesis analyzed the holding power of religious denominationson college students. The results of the questionnaire indicated that the most significant variable was the character of the denomination itself, followed by the amount of religious education, sex and age. The Catholic denomination, the cohesion of which is nurtured by weekly public worship and the parochial school system was the most significant variable in determining the degree of commitment as well as the holding power for Catholic students. The other demographic variables of years in college, residence, nationality, parents t educational background, occupation or family inoome were not significant.

Finally, students at Buffalo State reflect the optimism of Mol in that religious denominations, like religion itself. will continue to exist in American society. Although the students distinguished between their belief in God and their loyalty to a denomination, the holding power of the denominations is high, which indicates that they continue to act out their religious beliefs with a support group of like minded individuals called a denomination.

abstract: It has been observed that the radiation response of a cell line may positively correlate with baseline levels of reactive oxygen species (ROS) generation, which is facilitated, in part, by the function ofNADPH oxidase membrane proteins. Apocynin has been successfully used to inhibit ROS generation via NADPH oxidase for other uses. Here, the effectiveness of apocynin to improve sensitivity to radiation in the MATLyLu cell line was examined. MATLyLu-implanted Cop/Hsd rats undergoing lOGy/SfX radiation treatment demonstrated improved tumour control, as measured by survival time (to predetennined endpoints), when given apocynin orally throughout their radiation treatment, but not when given apocynin only before radiation. Rats given apocynin without radiation did not demonstrate improved survival over controls. MA TLyLu cells given apocynin in vitro, however, did not demonstrate improved response to radiation or a reduction in baseline ROS production on a per cell basis, and apocynin was found to inhibit growth when given alone. These contradictory in vivo and in vitro findings may be explained by certain proposed mechanisms of action for apocynin which requires it to be first synthesized into its dimer, diapocynin, before it will inhibit NADPH oxidase, and this synthesis may occur during ingestion. Further investigations with diapocynin and the MATLyLu cell line are required. Therefore the mechanism is uncertain, but it was concluded that apocynin and radiation administered together in vivo improves radiation response as compared to either treatment alone.

abstract:
A considerable amount of attention has been paid by political scientists to the rise of public voting support for third parties, including separatist parties in such western democratic states as Canada and the United Kingdom. This study, .however, attempts to probe within such a party in order to discover the characteristics of its active members rather than its voting supporters. It is hypothesized that here very different factors may be operating.

 The study focuses on a group of activist members of Plaid Cymru, the Welsh Nationalist Party, whose motivations and attitudes are diagnosed, together with their consequences for political action. The importance of cultural and idealistic as against political and economic motivations is examined, while the major attitudinal dimensions considered are those of political efficacy and opinions on the use of violence and other extra-legal methods, both of which are central to an understanding of the nature of Plaid Cymru as a political party. Finally, party activity, as an indicator of depth of involvement in the party, is examined, together with those factors which determine its intensity. In these ways it is hoped to construct a theory of separatist party involvement which may supplement existing models attempting to explain the rise of third parties.

abstract:
This study consists of an examination of the political philosophy of William Lyon Mackenzie King. An examination of King's book Industry and Humanity reveals his political philosophy, as expressed in his book, to be that of corporatism. Although a professed liberal and leader of the Liberal Party in Canada for many years, King's advocation of corporatism as a means of overcoming industrial and social conflicts, is seen as a conservative measure.
 King's success as a labour conciliator in industrial disputes during the early years of this century and later political success earned him the name of "conciliator". However in this study it is argued that King was in fact a "controller" of events. Data provided by the King diaries and other material in the literature has been utilized within the framework of Object-Relations theory. Within this framework inferences have been drawn to show that King was in fact a "controller" and not a "conciliator" due in part to an obsessive-compulsive personality.

subject: Other Languages, Societies, and Cultures

abstract:
A study of the place of Boris Pilnyak in Soviet Literature faces several practical difficulties; biographical data are scanty, critical material is very scarce, and some of his works are unavailable or difficult to obtain. Until greater latitude is allowed to Soviet scholars and until the author's works are more readily available, non-Soviet scholarship can only render preliminary judgments upon Pilnyak and his works. There is always the possibility that a substantial amount of "desk-drawer literature" by the author will be published at a later date.

The scope of this study is general, the basis of more detailed investigations in the future; Pilnyak is viewecl in the context of the 1920's and 1930's, the period in which he wrote the great majority of his novels and stories. Pilnyak is not only an interesting author, but also worthy of attention as a central figure in the struggle for power between various literary groups or camps.

The first part of this thesis deals with Pilnyak the author -- his concern with the Revolution, his themes, and his characters. The second half of the thesis deals with Pilnyak the literary politician-- his role in the Union of Writers and his difficulties with the Soviet literary and political establishments.

I hope to attain two goals as a result of this study: 1) to shed some light upon Boris Pilnyak as an author and personality; 2) to delineate the fratricidal struggle in the literary arena of the late twenties through the case of Boris Pilnyak.

I have used the transliteration of the name "Pilnyak" which is most common in English; the correct form is "Pil'njak."

All quotes from Pilnyak's works are in Russian, with the exception of those quotation which are llvailahle only in English.

I wish to express my gratitude to Dr. Louis J. Shein, Chairmnn of the De-partment of Russian, McMaster University, and to Dr. C. ,J. G. Turner, for their advice and assistance.

I also wish to thank McMaster University for granting financial assistance in the form of a Graduate Teaching Fellowship.

title: THE EARLY HISTORY OF THE MYTH OF THE ARGONAUTS

subject: Classics Classics

abstract:
When we think of Greek epic, our minds generally fly at once to the great poems attributed to Homer, or perhaps to the works of the Epic Cycle, standing in the shadows of the Homeric poems. Similarly, when we consider the great stories of Greek epic, we immediately think of the Trojan War, the Wanderings of Odysseus, and the Voyage of the Argonauts. A comparison of these two casual impressions reveals one strange feature: while the standard versions of the tales of the Trojan War and its aftermath are known to us from the Homeric poems and the Cyclic epics, our fullest and most definitive version of the myth of the Argo comes from the pen of the third century B.C. Alexandrian writer, Apollonios Rhodios.

The fact that Apollonios chose the legend for his subject would seem to indicate that no previous author had made it his own, as Homer had done with the story of Odysseus. But in spite of this, the story of the Argo was a popular and very old myth, as is indicated by Euripides' tragedy Medea, and by the Homeric reference to Αργω πασμελoυσα , παρ' 'Αηταο πλεουσα (Odyss. XII, 70). Clearly the subject had been treated by authors previous to Apollonios, and the myth was well-known to the poet of the Odyssey.

The myth has been investigated by Miss J. R. Bacon (The Voyage of the Argonauts, Methuen, London 1925), but the object of our study will be to examine the treatment of the myth in the early literary sources, and to attempt some reconstruction of the versions which they presented. This approach will lead us into areas which were not fully examined by Miss Bacon, notably the treatment of the myth in early epic. The examination of the different versions should enable Us to see more clearly the development of the myth. It is hoped that this study may enable us to discover the character of the myth in Homeric times and earlier, and perhaps also to trace it to its ultimate source. In view of this, it will be best to work back through the several authors in an approximately chronological order (as far as this can be determined).

Of the authors to be examined, two will come readily . to mind. first there is Pindar, whose Fourth Pythian Ode provides us with our most complete surviving account of the myth before Apollonios, and which, therefore, will be the best place to begin our researches. Secondly, no examination of an early epic subject can be made without reference to the works of Homer, to whom, as we have already noticed, the Argo was wellknown.

For other sources to be considered, we shall be guided by the Scholia to Apollonios Rhodios, which often cite the versions given by other authors. Since we have decided to restrict our examination to the work of Pindar and authors previous to him, four sources would seem to be worthy of consideration. These are the genealogist, Pherekydes of Athens, the Boiotian poet, Hesiod, and two early epic poets, Eumelos of Corinth, and the author of the epic called the Naupactia. A chapter will be devoted to the treatment of the myth by each of these authors in turn. Finally, we shall examine the possible origins of the story, and end by outlining the development of some aspects of the myth from the earliest versions up until that of Apollonios.

For those of our authors whose work survives only in fragments, references will be given as follows: for Pherekydes they will be to F. Jacoby's Die Fragmente delr griechischen Historiker. Pherekydes is the third author listed by Jacoby, so references will be in the form e.g. 3 F 30 J, meaning the thirtieth fragment of Pherekydes in Jacoby's FGH. References to other authors in FGH will be given in a similar manner. For Hesiod, references are to Carmina Hesiodi (second edit. Teubner, 1902), by Rzach, and will be in the form e.g. F 50 Rz2, meaning the fiftieth fragment in Rzach's second edition. For the two early epic writers, references will be to Epicorum Graecorum Fragmenta (Leipzig, 1877), edited by Kinkel, e.g. Eumel. F 2 K; Naup. F 10 K. The edition of the Scholia to Apollonios will be Scholia in Apollonium Rhodium Vetera (recens. C. Wendel, Berol. 1935).

subject:

abstract:
This Thesis seeks to demonstrate that ethnic cleavages on the part of the major Nigerian groups (the Hausa-Fulani, the lbo, and the Yoruba) coupled with the very nature of the British colonial heritage, made political integration impossible in Nigeria's first Republic. Nigeria was created artificially by the British to enhance Colonial objectives; there were not enough attempts by the Colonial administration to create a unified state. Moreover, 'Westernization' which has been usually associated with 'development' did not spread evenly across the country. The result, therefore, was competitive ethnic antagonism between the 'Westernized' Ibo and Yoruba on the one hand, and the 'non-Westernized' Hausa - Fulani on the other . This led to the ethnic political parties fighting bitterly to maximize their positions in national politics: elections were rigged, census figures distorted and undemocratic practices became rampant . The Army took over the government in a coup d'etat in January, 1966 and its aftermath was a civil war that finally destroyed the first Republic (1966 – 70).

This work is therefore concluding with the argument that, given the fragile nature of Nigeria's political existence, there should have been attempts on the Nigerian ethnic groups to accommodate one another through a form of elite cartel at the centre . An arrangement of this nature is usually known in the literature as "consociational democracy" (elite accommodation). Perhaps such a measure might have saved the state from crumbling the way it did.

The CNC software base consists mainly of Assembly language routines written for the HP-2100 minicomputer for the editing and debugging of N/C data programs. The Adaptive Control system consists of a cutting force transducer, and an Analog to Digital Processor which supply input to an A/C routine resident in the HP-2100 minicomputer. The Adaptive Control system and the cutting forces encountered in milling were simulated in computer programs. The system was stabilized by using the simulation to predict the response of the actual system.

abstract: The Century Project, both art exhibit and book, consists of unconventional nude portraits of over one hundred girls and women from the moment of birth to old age. Accompanying each photograph is the subject's written statement detailing instances of abuse, violence, grief, or reflecting moments of humour and joy. In the following pages I endeavor to understand the affect of such an exhibit by engaging the multiple and sometimes contradictory aesthetics exhibited by each photograph. Having both posed and volunteered for The Century Project, I mix personal engagement with critical theory, as difficult as it sometimes is to distinguish where one form of engagement ends and the other begins. I understand the bodily expression of both subject and viewer as an active, generative force: potentially both creative and uncooperative in response to authority and discipline. Engaging theories of embodiment, photography and psychoanalysis, I situate The Century Project in its various contexts: a corrective to iconic feminine beauty, a model for relational identity, and an expression of unconscious ideologies.

This involves an inquiry into the problem of Hekate's original homeland and, as far as can be determined, her character there, as well as the examination of her role in each of the above mentioned poems and a discussion of the possibility that the passages dealing with Hekate are interpolated.

contributor:
Goellnicht, Donald
English

abstract: This thesis investigates the first and second diasporic generations' approaches to "home" as represented in Dionne Brand's What We All Long For and Madeleine Thien's Certainty. Brand and Thien offer nuanced and counter-intuitive conceptualizations of "home" that emerge in the house, city, and world at large. The authors demonstrate how one's achievement of "home" does not only entail a negotiation of these spaces, but also of familial relations. This thesis argues that the first generation's "diaspora consciousness" is a trait that the second generation inherits and transforms. This second generation exhibits more of a "transnational consciousness," a term that this thesis offers to describe the nomadic lifestyle of the second-generation characters.

title: Idealists, Realists and Cynics in Timon of Athens and Troilus and Cressida

contributor:
Brennan, A. S.
English

abstract: It is suggested that Shakespeare reveals in his work a continuing interest in the variety of human responses to societies whose members no longer adhere to traditional social and moral values. It is maintained that in certain plays the emphasis lies more on these responses and their implications than on the unique personalities of the characters themselves. In such plays the primary interest of the poet is seen to be in a triadic division of attitudes towards and responses to the same social conditions. The characters exhibiting these attitudes are here referred to as idealists, realists and cynics. It is argued that idealists are presented as being admirable in some respects but inadequate as leaders of their respective societies and often ultimately dangerous both to themselves and to their fellow citizens. It is further argued that cynics are portrayed as fulfilling no positive function in their societies and are even destructive insofar as they foster their own negative attitudes in others. The point is made that the realists can be seen to serve both their own interests and the interests of their societies and may therefore be best fitted for leadership under the prevailing social conditions. It is acknowledged that Shakespeare's realists are on occasion to be found in situations where no moderate; realistic solutions are possible. These general hypotheses are first briefly examined in relation to King John, The First Part of King Henry IV, King, Henry V and Coriolanus. They are then examined more thoroughly in Timon of Athens and Troilus and Cressida in which, it is maintained, the triadic division of attitudes involving idealism, realism and cynicism may be most clearly perceived.

title: Phallacies of Modern Masculinity: An Examination of Erectile Dysfunction as a Social Disability

contributor:
Brophy, Sarah
English

abstract:
This thesis critically evaluates the impact of Viagra's marketing campaigns on social constructions and expectations of masculinity and masculine identities in Western society. Specifically, this project examines the implications of Pfizer's presentation of heteronormative patriarchal figures of male authority in Viagra commercials and print advertisements. In my analysis, I draw on gender theorists Judith Butler and Susan Bordo to clarify how codes of gender are established and policed within Western society. I also draw on the work of disability theorists Rosemarie Garland-Thompson and Thomas Gerschick in order to challenge the categorization of 'normal' bodies and identities. In this thesis, I argue that by distancing sexual functioning from the construction of individual identity, it becomes possible to challenge the social expectations and limitations placed on enactments of gendered sexual identity.

In Chapter One, I lay the groundwork for my discussion of erectile dysfunction by examining the body as a site of identity formation and considering theories of gender construction. By critically evaluating the existence and implications of social constructions of 'normal' bodies, it is possible to challenge the ideals of physicality that are so prevalent in Western society. I also consider the way that these ideals are mobilized in advertising in order to transform the 'desirable' body into a profitable body. In Chapter Two, I engage in a careful analysis of the Viagra commercials put out by Pfizer from 1998 to 2005, tracing the evolution of ' desirable' male bodies and identities. I argue that Pfizer's use of increasingly youthful spokesmen is indicative of an attempt to play upon men's anxiety concerning 'normal' sexual performances. My discussion then moves to a consideration of how men with physical disabilities create sexual identities in a society that values normative modes of embodiments and often dismisses alternative sexualities. From here, I argue that by viewing erectile dysfunction as a disability rather than a medical condition, it may be possible to create new definitions of male identity that are not contingent on normative sexual performances, thereby challenging socially validated constructions of 'normal ' gendered sexual identity.

title: Anodyne Aesthetics in Ann Radcliffe's The Mysteries of Udolpho

contributor:
Walmsley, Peter
English

abstract: This study is a sustained exploration of Ann Radcliffe's engagement with art and aesthetics in her most lengthy novel, The Mysteries of Udolpho. While critics often address how Radcliffe draws upon the eighteenth-century aesthetic categories of the sublime and the picturesque, such considerations often cast her efforts as simply transcriptions of the pictorial works of landscape painters, or translations of theoretical concepts into narrative form. Instead, I argue that Radcliffe structures her narrative around her heroine's aesthetic encounters, and thus negotiates with the very conception and classifications of aesthetics of the past, present and imagined futures, in order to work through concerns of gender and class on the fundamental level of cognition, representation, and modes of reality. Chapter One ("The Limits of an Aesthetic Education") traces the thematization of the bequest of education and challenges the notion of St. Aubert as a benevolent patriarch. Instead, his teachings of reason and sympathy expose the internal contradiction between sentiment and scientific rationalism through which Radcliffe exposes the limits and relevance of such an education to her female subject in her confrontations with the aesthetic categories of the sublime and picturesque. Chapter Two ("The Aporias and Aesthetic Excess of St. Aubert's Philosophical Legacy") focuses on the death sequence of St. Aubert where Radcliffe foregrounds how his lack of a philosophy for mourning disables his daughter, and the consequences of the inherent melancholic disavowal which underlies St. Aubert's many philosophies become most tangible through aesthetic figures. Chapter Three ("Authorial Agency, Gendered Voice, and the Limits of Language") traces the metatextual instances where figures of reading convey Radcliffe's interrogation of the limitations of her own medium and how imagination is a necessary interpretative dimension of cognition, but one that is vulnerable to fear created by tyranny and isolation. Chapter Four ("Italian Aesthetics and Culture") explores Radcliffe's allegiance to a pastoral, and decidedly anti-Baroque aesthetic where she censures the preference for simulacra and increasingly critiques how so-called renaissances of culture often revive the stylistic surfaces and luxuries of the past where Venice becomes a figure of false hospitality and culture. Chapter Five ("Domestic Discord and Anodyne Endings") reconsiders the notion that Radcliffe defers to a so-called normalizing ending thus subduing the potential critiques of the text. Chapter Six ("Emily's Psychic Development and Search for Feminine Legacies") concludes with a psychoanalytic-based interpretation of the heroine's growth and demonstrates how her struggle with aesthetics throughout constitutes a search for sublimated female presences and suggests the possibility for Subjectivity through artistic reparation.

title: Re-Presenting Biblical Women: Fictional Re-Vision as Feminist Criticism

contributor:
Grisé, Catherine
English

abstract:
Using Anita Diamant's The Red Tent, India Edghill's Queenmaker Margaret George's Mary, Called Magdalene, whose texts recreate/re-envision the lives of Dinah, Michal, and Mary Magdalene respectively, this project focuses on fictional portraits of biblical women who are either silent or whose histories are relayed, possibly inaccurately, in the original biblical accounts. The development of this popular sub genre of historical fiction can be viewed as part of the tradition of feminist biblical scholarship, which focuses on the examination of biblical women and their experiences and identities, the omission of women as narrators in the Bible canon, and the subsequent position of women in the church and in other social structures.
 My research indicates that there exist two opposing bodies of feminist biblical critics: on one side there are the 'rejectionist' feminists who argue that the Bible is the handbook of patriarchy and that, consequently, its theological traditions must be rejected by women. On the other side there are the 'reinterpretationist' feminists who refuse to give up on the authoritarian and liberating power of the Scriptures and insist that, through reinterpretation, women can be empowered by the Bible. Throughout my consideration of fictional re-imaginings of Bible women's histories, including the ways in which these novels re-present female knowledge and power, I consistently address the need for a negotiation between the rejectionist and reinterpretationist paradigms that resolves their individual inherent inadequacies. My project asserts that rewriting biblical histories using the genre of the novel enables theorists to transcend the boundaries and limitations imposed on the discipline by the contrasting theoretical paradigms and create a third, hybridized approach to critiquing the Bible from a feminist perspective that both rejects and reinterprets biblical narratives.
 My project focuses on the theoretical function of revisionary novels in feminist biblical scholarship, although it invites a further consideration of the valuable stake that these novels might claim in the wider arena of theological discourse.

contributor:
Walmsley, Peter
English and Cultural Studies

abstract: After battling savage beasts, wild storms, and his own fears, a shipwrecked man finally escapes his island prison by means of the flying machine he has constructed using his own ingenuity and bits of debris washed ashore. Francis Godwin, Robert Paltock, and Ralph Morris, in their respective narratives Man in the Moon, The Life and Adventures of Peter Wilkins, and The Life and Astonishing Adventures of John Daniel, build their narratives on variations of that plot. Their proto-science fiction texts, written in the seventeenth and eighteenth centuries, while intended to titillate and amaze their readers, also purposefully highlight the positive potential of experimental science. They respond to doubts and criticisms of the natural history espoused by people such as Francis Bacon, Thomas Sprat, and Robert Boyle, but satirized by authors like Jonathan Swift. Swift, in Travels into Several Remote Nations of the World, questions the claims of empirical scientists who aver that natural history can praise God and benefit society. Using their texts as laboratories and mixing religious imagery and metaphor with technological advancement, Godwin, Paltock, and Morris experiment with the potentialities and implications of science, concluding that the natural historian can be both a good Christian and an aid to his community. This project, therefore, delves into questions of science, community, and the Church in the seventeenth and eighteenth centuries, building on previous studies of actual natural historians, but focussing instead on fictional representations of Christian scientists.

abstract:
This study examines the relationship between the internal decision making and administrative structure of the federal New Democratic Party and the Party's policy outlook. Other work done on the NDP has tended to concentrate on the influence Canadian political culture has exerted on the Party's policy perspective.

The thesis argues that although the Cooperative Commonwealth Federation initially put forward a platform containing liberal and socialist elements, liberalism now has an overwhelming influence on the NDP's programme. The examination of the NDP's internal organization reveals that it has fostered the adoption of a liberal approach by the Party. Within the NDP's organization, the leadership and policy selection processes, the importance of the parliamentary caucus relative to the Party, the nature of organizations affiliated with the NDP, and the relationship between the federal and provincial sections of the Party have combined to encourage a liberal policy perspective.

In conclusion, it is argued that the assumption of a more socialistic policy perspective by the NDP could be facilitated by changes in its organization. The assumption of such an approach is dependent upon the Party strengthening its federal section, enlarging the presence of its left wing in the leadership, and increasing the proportion of seats held by the NDP in the House of Commons.

title: American Exceptionalism in Toni Morrison's Beloved and Paradise

contributor:
O`Connor, Mary
English

abstract: This study considers the critique of American exceptionalism in Toni Morrison's Paradise and Beloved. While much African American fiction, particularly classic slave narratives, employ critiques of exceptionalism, most of these critiques appeal to the nation's failure to live up to its claims of greatness. These critiques focus on the hypocrisy of a nation that makes claims to American greatness despite the nation's racial exclusions and inequalities. Morrison's critical and creative work, on the other hand, suggests the interlocking racial, gender, and economic oppression of African Americans is absolutely crucial to the development and maintenance of America's exceptionalist ethos. Defining themselves against its black population, European America, Morrison argues, was able to develop a powerful exceptionalist self-image. From this perspective American racial, imperialist, and sexual domination is not a contradiction of but is instead inevitably implicated in American exceptionalism. Using Morrison's critical work as a starting point and methodological framework I investigate the various ways exceptionalism is registered in the two novels. Chapter 1 outlines the history of exceptionalism drawing out the key points of its development from the Puritans through the twentieth century, particularly as this mythology was employed in the field of literary studies. Outlining Morrison's critical work on the nation and the "Africanist presence" alongside her self-professed use of paradoxically pregnant silences, I lay the groundwork for an investigation into the two novels' unwillingness to use exceptionalist rhetoric to advance the cause of social justice. Chapter 2 discusses Beloved's historical context and the resurgence of the exceptionalist mythology in the Reagan years when the achievements of Civil Rights were being undermined by neo-conservatism. This context, along with a discussion of the generic codes of the slave narrative, frame a consideration of Beloved's lack of overt appeal to the mythology, a pregnant silence that strategically undermines the idea that America, because it abolished slavery and granted Civil Rights, is a model of freedom and democracy, an exceptional nation on the world stage. Chapter 3 reflects upon Paradise as a critique of exceptionalism as a misogynist mythology that both justifies and produces war and imperialism. The chapter draws out the links Paradise makes between domestic racism and imperialist wars abroad by way of Morrison's consideration of exceptionalism. Ultimately, Morrison's work offers an imaginative, critical contextualization for the contemporary American wars of aggression and the current resurgence of the exceptionalist mythology.

title: Myth, Metaphor and Symbol in the Early Novels of Morley Callaghan

Hyman, R.

English Language and Literature

abstract:
In the memoir That Summer in Paris, Morley Callaghan's vehemence regarding metaphor is pronounced. He is critical of writing that, in his view, examines the object in terms of some other thing and he insists upon a direct relationship between language and what is being described. Reflecting his expressed convictions, Callaghan's own writing style in the early novels is plain, at times even prosaic, seemingly stripped of shading and nuance. Callaghan's protagonists correspond to his style for they are all "ordinary" in the sense that they do not experience extremes either of wealth or poverty, heroism or ignominity, power or impotence. A close examination of the early novels reveals, however, that although his style is plain, it is far from simple and Callaghan himself uses metaphor, myth and symbol abundantly in his writing. Each of his protagonists, though "ordinary", is confronted with a profound moral dilemma whose outcome depends upon a clear, though frequently subtle perception of truth.

In each of the early novels, the significance of seemingly unimportant detail enhances the single vision of life that Callaghan presents. In the context of each novel and the context of the early work as a whole, Callaghan's vision of life is based upon the acceptance of man as he is, neither naturally innocent nor naturally evil, but dependent upon his ability to distinguish truth from falsehood in his struggle for physical and spiritual survival. The early novels span a period of nine years, from 1925 to 1937 (More Joy in Heaven, published in 1937, is excluded in this study because of length requirements since its theme is somewhat similar to Such Is My Beloved). Callaghan's growing mastery of female characterization during this period corresponds with a decline in the influence of tangible Christian, and especially Roman Catholic symbols, such as the cathedral and its soaring spire. Without in any way diminishing the intangible values underlying the Christian faith, Callaghan emphasizes the need for individual responsibility as he probes the relationship between the recognition of truth and the survival of the contemporary human being in a materialistic, success-oriented society. By confronting myth, using symbol innovatively and employing metaphor to enhance truth and expose fraud, Callaghan's writing credo, as he sets it out in That Summer
in Paris, is confirmed through the early novels.

title: A Study of Entrances in Four Plays of Aristophanes

contributor:
Slater, W.J.
Classics

subject: Classics Classics

abstract:
This thesis is an approach to the subject of the production of Aristophanic comedy. Much scholarship over the years has treated the plays as literary works and as social documents, but proportionately little thought has been given to a consideration of the comedies as theatrical productions. One cannot ignore the value of concentrating on the former, but at the same time further and fuller appreciation of both the poet and his plays is ,to be gained by approaching the comedies as scripts without stage directions. It is this latter aspect of Aristophanes with which the paper is concerned.

Entrances are an integral and extremely important part of "non-static" drama; the entrance of a new character is the appearance of a fresh element into the play, and therefore it possesses a crucial dramatic importance. It is, however, all too easy when reading a play to take the entrance of a character for granted, and in doing so to ignore its dramatic function. Accordingly this paper attempts to reconstruct, as closely as is possible with only the text to work from, the staging of entrances as they might have been produced in the fifth century B.C.

title: Theme and Image in Alice Munro's Fiction

contributor:
Ferns, H. J.
English

abstract:
Alice Munro's fiction has a distinctive style that grows, in part, out of the close relationship between her themes and images. The main concern of this thesis will be to explore the way in which Alice Munro uses certain key images to dramatize the central themes of her fiction. Munro's fiction examines the trials and occasional triumphs which the individual experiences in developing from chilhood and youth to maturity and offers the reader insight into the complex processes of life through her subtle rendering of human experience.

It is Alice Munro's perceptive dramatizations of life that mkae each of her short stories and novels memorable to the reader. She possesses the ability to present 'real life' vividly and convincingly as well as the talent to develop each story through her use of significant, and often recurring, images. These images are sometimes introduced
obliquely at first, yet the reader is made aware of their significance because of Munro's skillful attention to dramatic and sensuous detail. When each story reaches a climax or epiphanal moment it is because its images have been cumulatively built up and dramatically emphasized as essential to our grasp of the climactic moment and most important aspects of each novel or story's theme.

The themes in each of her four works of fiction are similar and are often repeated in greater depth from earlier to later works. As a writer of fiction, Munro has created collections of short stories and novels which are basically concerned with the maturation process and the recognition of moral and social pressures which can influence the
individual. Munro's images are often sensuous and uncomplicated to begin with, mirroring the attitudes of her predominantly youthful narrators. As the individuals in her
stories grow to understand some of the pitfalls of society, Munro's images sometimes become unnatural and almost threatening. In becoming so they reflect the corruption and pressures of society which produce the madmen, suicides and cripples of her world who are the deprived manifestations of society's spiritual deformation.

abstract: This thesis examines the influence of the Roman Catholic Church on the modernization of Colombia. Although a history of the Church's political involvement is included, the major emphasis is on the recent changes in the role of the Church in Colombia that have been prompted by the Vatican and by pressure from leftist priests within the country. The activities of various groups of these progressive priests are examined and the validity of their contribution to the modernization process is questioned. Despite the struggles of the leftist clergy, it is concluded that because of the position of the hierarchy of the Colombian Church and the nature of the Church's ties to developed countries, unless there are further radical changes in the position of the Colombian Church, it will not be a significant force in the necessary restructuring of Colombian society.

title: The Gentleman's Magazine: 1770 - 1780 - A Study in the ExpressIon of Editorial Opinion

contributor:
Morton, Richard
English

abstract:
The occasion for this study was a need for an analysis of the success of the Gentleman's Magazine in order to place its editorial policies and practices in proper perspective. The important work of C. L. Carlson and of James M. Kuist has focussed on the magazine's editorial history from 1731-1754 and from 1754-1800 respectively, but this particular study attempts to examine the editorial function in terms of the position of the Gentleman's as a successful periodical in the eighteenth century. The study, therefore, does not pretend to be a narrative; it is analytical rather than descriptive.

Editorial involvement in the magazine was pervasive and complex. The Introduction provides necessary background to the study. Chapter II examines editorial policy and factors affecting its formulation and successful development. Chapter III discusses the nature of the magazine as a form of periodical. Furthermore, that section examines editorial criteria, methods and general presentation of materials in order to determine their effect on the magazine itself. Chapter IV analyzes the magazine's appeal from the viewpoints of the editors and the correspondents in order to assess further the success of the Gentleman's. That chapter develops the hypothesis that, in their attempts to be successful, the editors seriously compromised their claims to impartiality by involving themselves so completely within the magazine. Finally, Chapter V concludes that the establishment and continuation of the Gentleman's as a successful magazine with its basic ideas, form, criteria and personalities did not necessarily ensure the most effective presentation of literature.

The policies adopted by the founders of the Gentleman's generally remained stable throughout the century. To facilitate analysis of that stability the study draws specific examples from a period roughly analagous to the 1770's. However, examples throughout the magazine's history in the eighteenth century appear in order to demonstrate the unity and complexity of the whole development of the periodical. Furthermore, the stableness of the Gentleman's was the result of the efforts of individuals. Those personalities associated with the magazine were primarily interested in the continuation of its success and in its general welfare for a variety of reasons. An examination of the involvement of those people in the magazine is a study in the expression of editorial opinion which, in turn, demonstrates and accounts for the success of the Gentleman's in the eighteenth century.

abstract: The magnetization of the Heusler alloys NixCu₂-xMnSn has been measured. These alloys, of the form X₂YZ, have been investigated in order to determine the X site dependence of the interactions which are responsible for the ferromagnetism. It is seen that the Curie temperatures vary nonlinearly with composition suggesting that the short range interactions which determine them vary in a similar manner. Saturation moments are found to remain constant; however, a decrease in paramagnetic moment as the copper concentration is increased, is attributed to disorder.

abstract: This thesis is concerned with the electoral cleavages in Metropolitan Hamilton as demonstrated during the 1963, 1967 and 1971 Provincial elections and the 1962, 1965, 1968 and 1972 Federal elections. Through the use of ecolgocial data found in the 1961 census bulletins and the poll-by-poll election results for the above elections an effort is made here to examine sources of consistent party support and areas of fluctuation. Thus, this thesis has attempted to demonstate that there are distinct social class differences between sources of party support in the study area. The data presented in this thesis is analyzed in order to provide a descriptive picture of voting patterns in Metropolitan Hamilton and the relationship this has with the nature of federal and provincial electoral politics in the province of Ontario.

abstract: This study attmepts to present a thorough comparative analysis and evaluation of Brecht's Coriolan adaptation and his Shakespearean model. Brecht's actual achievement is measured by the standards of his critical theory of literary adaptation of classical drama, and especially of Shakespeare, on the modern, 'epic' stage. It is shown why Brecht's insistence on shifting our central interest and sympathy from the hero, on whom Shakespeare had focussed the entire action, to the people's collective, had to result in an admirable failure.

abstract: In a news industry that seems to have lost its way, The Daily Show with Jon Stewart occupies a critical space in the public sphere, remapping traditional news categories to create a hybrid official/alternative/popular style, and restructuring audience demographics to include leftist college students and moderate conservatives, all of whom flock to a format that resolves to search for truth and to combat those who stand in its way. Host Jon Stewart is a revolutionary public figure who combines the roles of concerned citizen, comic activist and public intellectual to gain trust, moral authority, and respect from an audience tired of the split-screen debates, punditry and bullshit, and thirsty for a reinvigoration of critical analysis and political engagement.

title: Dracula: A Romance

contributor:
Sigman, J.
English

abstract:
Although there have been a large number of studies done on the subject of vampires which indirectly deal with Bram Stoker's Dracula, there have been very few attempts to examine the novel from a literary perspective. There are a few works which chronicle the appearance of the vampire in literature, but these tend to be essentially anthropological or historical studies. The only extensive literary analysis of the novel is that provided by Leonard Wolf in A Dream of Dracula. Wolf characterizes Dracula as a gothic romance and then proceeds to examine the novel within the tradition of the gothic novel.

While this study deals briefly with the influence of the gothic tradition on Dracula, in essence it is an attempt to examine Dracula within the context of romance literature and the conventions of that tradition as articulated by Northrop Frye. An analysis of the novel is put forward based on Stoker's use of these conventions. Thereaher, the conventions of romance and the analysis of the novel which they suggest are then discussed with re ference to various theories of the psychological significance of romance; most notably the theories of Carl Jung and his disciple, Erich Neumann.

title: "One Woman with Many Faces": Imaginings of Mary Magdalen in Medieval and Contemporary Texts

contributor:
Grisé, Annette C.
English

abstract:
In recent years, an interest in religious (especially Christian) discourses has resurged, as evidenced by the popularity of the conservative Catholic film, The Passion of the Christ (2004) and Dan Brown's Church-conspiracy thriller The Da Vinci Code (2003). My thesis explores the character of Mary Magdalen within such texts, comparing her
contemporary imaginings with the imaginings of late medieval English texts. This
comparison emphasizes the similarities between each archive--both eras are intent upon adding to the content and meaning of Mary's story-and their differences in purpose-medieval texts are largely devotional, contemporary ones much more iconoclastic. I examine such disparate texts as The Golden Legend, a late-medieval play called Mary Magdalen, films Jesus Christ Superstar (1973), The Last Temptation of Christ (1988), Jesus (1999) and The Passion of the Christ, thriller The Da Vinci Code and Nino Ricci's novelization Testament (2003). Each text depicts Mary with a different role, and she often plays more. than one role in the same text. The narrative impulse is so similar in both archives that I believe it is not possible to read the medieval archive as a less progressive version of the contemporary one-neither is immune to misogyny, neither is entirely misogynist. The constant reinterpretation of Mary Magdalen engenders a hybridity in her characterization; using Bakhtin's concept dialogism and some mythographic theory, I argue that the paradoxality and plurality of these reimaginings allow her to become a central part of the unfixing ofmeaning in the gospels. Using feminist theology I argue that Mary's marginality makes her an ideal site for such imaginings.

title: The Idea of Dualism in Some Shorter Works of D.H. Lawrence

contributor:
Aziz, Maqbool
English

abstract:
The thesis attempts, by a chronological examination of a selection of Lawrence's shorter works, to explore Lawrence's attitude toward a particular aspect of dualism: the mental and physical duality of man. The chronological sequence enables the reader to trace the similarities and developments in Lawrence's treatment of this problem over the course of his career.

By means of close textual analysis, the thesis reveals how Lawrence effectively presented his philosophical viewpoint through the medium of fiction.

This thesis also stands as an apologia for Lawrence's shorter works, which, to date, have not received the critical attention which they justly merit.

abstract:
This thesis describes an experimental study of hydrodynamically suspended cylinders and cylinders modified by end cap(s) in a vertical pipeline, using water and polymer solution as the fluid medium.

The experiments involved hydrodynamically suspending steel and aluminium cylinders in a pipeline for the sphere to pipe diameter ratios of 0.434 to 0.864. Drag coefficients were found from a force balance which involved measuring the average velocity of flow near the cylinders as well as the pressure drops across the cylinders. The experiments on cylinders were done in both water and dilute aqueous polymer solutions, while the tests on cylinders modifies by end caps were done in water only. The length to diameter ratios of cylinders used in this study ranged from three to fourteen.

Comparison of results from this study of those obtained by other authors especially Hoerner(¹³), McNown & Newlin(¹⁸) and Aly^(³⁰) were made.
