Jorge Luis Borges y Mircea Eliade: Dos metamorfosis del laberinto literario
Creators: name: Winnicki, Ioana

Subjects: subject: Language, Modern.

description: This comparative study between eight fantastic narratives written by Jorge Luis Borges - Argentine poet, essayist and writer-, and Mircea Eliade -Romanian historian of religions and writer-focuses on the figure of the labyrinth as a metaphor of literature and an epistemic symbol. The approach is based on Hans Georg Gadamer's hermeneutical theory, holding that texts are "inexhaustible," in the sense that every historical moment generates a new interpretation, and therefore the meaning is produced during the reader's encounter with the text. The argument is twofold. Firstly, based on Mikhail Bakhtine's theory of the chronotope in literature, the work examines the way the labyrinth, a fundamentally spatial figure, acquires a temporal coordinate, in the literary text. Secondly, it argues that there is a significant difference between the two authors, regarding the connotations of the destination that the travellers reach. At the end of their voyage, the protagonists -motivated by the ancestral longing for immortality, the quest for an existential mystery, and the desire to transcend the human boundaries- find something that is linked to the way in which the literary texts integrate elements from anthropological, religious and philosophical discourses. The analysis of their journey toward the centre of the labyrinth leads to a questioning of the nature of the real, an aspect that each author envisions differently. The mythical and theological meanings that can be attributed to the labyrinth in other discourses function in Borges's literary universes according to a different logic. In his works, this figure is mostly a metaphorical configuration of literature, which becomes reproduction of and reflection on itself, and hence its non-referential nature. Paradoxically, in Borges, the real is the experience of the unreal and it is absurd, incomprehensible and unsubstantial. Eliade's literary labyrinths are closely connected to the works of the historian of religions. In his literature, the real is the experience of the sacred and it is, therefore, moving, significant and substantial. In conclusion, the experience through the labyrinth as a literary journey in Borges, and an encounter with the sacred in Eliade are means of accessing a different reality, in the ceaseless effort of the human being to transcend the chronological time.
title: Choice Reaction Time as a Function of Set Size and Signal Frequency
Creators: name: Herzing, Barbara M.
Publisher: name: Old Dominion University
publisherIdentifier: https://ror.org/04zjtrb98
publisherIdentifierScheme: ROR
Year: 1992

description: This research was conducted in two experiments. The first experiment assessed whether set size for the negative and positive sets affected reaction time during a visual scanning task. The effects of signal frequency on these relationships were assessed in the second experiment. It was hypothesized that as set size increased, reaction time would increase. In addition, as signal frequency increased, it was hypothesized that reaction time would decrease. In the first experiment, 12 groups of 10 subjects each were tested varying the number of stimuli for the positive and negative sets. The second experiment tested 18 groups by varying the levels of the positive and negative set size, as well as varying the proportion of the stimuli presented for each group. Reaction time served as the major dependent variable for each group of subjects. The results indicate that the size of the positive set does affect reaction time; however, the size of the negative set does not appear to affect reaction time. As the proportion of the stimuli presented in the positive set increased, reaction time was found to decrease.

An introduction to classical gauge theory in mathematics and physics
Creators: name: Cornell, Brennan
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2008
Subjects: subject: Mathematics.
subject: Physics, Theory.

description: We describe some aspects of classical gauge theory from the perspective of connections on vector bundles. We begin by examining classical electromagnetism, and use it to motivate the development of gauge theory on vector bundles. If G is a Lie group, we review some of the theory of vector G-bundles, their associated principal G-bundles, and the related theory of connections. We then discuss the idea of gauge transformations on principal and vector G-bundles, and view electromagnetism as an example of an abelian gauge theory. We briefly review the action principle in order to describe non-abelian gauge theories such as the Yang-Mills equation. Finally, we present the main results from an article by John Baez entitled "Higher Yang-Mills Theory" where he attempts to abstract Yang-Mills theory using some concepts from category theory.
Non-contact measurement and characterisation of armour ceramics
Creators: name: Kesharaju, Manasa
Publisher: name: Swinburne
Year: 2024

description: The motivation for this research was the requirement for providing a reliable, cost effective non-destructive testing method for identifying defects in Armour Ceramic components. At present, Armour Ceramic components are inspected using an X-ray technique and its effectiveness is based on human interpretation of the X-ray images. Furthermore the X-ray technique does not enable differentiation between certain types of defects in the presence of density variation. This research relates to the development of an intelligent inspection system based on high frequency ultrasound for rapid, reliable and cost effective identification of defects in Armour Ceramics. The decision making in relation to the inspection task is automated using artificial intelligence based signal processing and data interpretation techniques.
Stabilization of an FM active harmonic mode-locked fiber laser at high repetition rates
Creators: name: Bouchard, Line
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2005
Subjects: subject: Physics, Optics.

description: A new and simple approach was optimized for stabilizing a harmonic active mode-locked fiber laser at 40GHz. A computer tunes the modulation frequency in a 500kHz band near 40GHz to follow variations in the optical cavity length. A second approach based on a Proportional-Integral ( PI) controller and a piezo fiber stretcher was also developed and optimized. This approach uses a circuit-controlled piezo (PZT) device to physically counteract optical cavity length variations. The optimized circuit-controlled and computer-controlled approaches were compared to draw conclusions on their performance. Results for the pulse characteristics, the side mode suppression ratio and the time jitter show that both approaches provide an efficient method for stabilizing a harmonic FM active mode-locked fiber laser at 40GHz. Finally, the versatility of both approaches was used to attempt to generalize the two methods for use at any modulation frequency up to 40GHz.

description: Porcine endogenous retroviruses (PERVs) are integrated in the genome of pigs and are transmitted like cellular genes from parents to the offspring. Whereas PERV-A and PERV-B are present in all pigs, PERV-C was found to be in many, but not all pigs. When PERV-C is present, recombination with PERV-A may happen and the PERV-A/C recombinants are characterized by a high replication rate. Until now, nothing has been known about the copy number of PERVs in wild boars and little is known about the prevalence of the phylogenetically youngest PERV-C in ancient wild boars. Here we investigated for the first time the copy number of PERVs in different populations of wild boars in and around Berlin using droplet digital PCR. Copy numbers between 3 and 69 per genome have been measured. A lower number but a higher variability was found compared to domestic pigs, including minipigs reported earlier (Fiebig et al., Xenotransplantation, 2018). The wild boar populations differed genetically and had been isolated during the existence of the Berlin wall. Despite this, the variations in copy number were larger in a single population compared to the differences between the populations. PERV-C was found in all 92 analyzed animals. Differences in the copy number of PERV in different organs of a single wild boar indicate that PERVs are also active in wild boars, replicating and infecting new cells as has been shown in domestic pigs.

subject: Health Sciences, Recreation.

description: The objectives of this study were to determine whether games-based computerized biofeedback training using the NeuroGym system reduces the attention demands of balance tasks in active community-dwelling older adults. Specifically, this study examined whether postural sway, reaction time, functional balance, and composite fitness changed following the training. Sixteen community-dwelling adults over the age of 65 who were experienced chair exercise participants were assigned to either a training group (n=9) or a control group (n=7). Participants in the training group followed an 8-week training program (2 x 30 minute sessions each week) consisting of five separate exercise routines using the NeuroGym system. The training routines required participants to play a computerized tennis game by shifting their body weight. Postural sway, reaction time, functional balance, and composite fitness were evaluated prior to training, after completion of the training and following a two week retention period.
La vertu dans l'éthique de MacIntyre

description: Notre mémoire porte sur le volet propositionnel dans l'oeuvre de MacIntyre. Plus particulièrement sur la vertu dans son éthique. Ce volet s'articule sur le schéma classique hérité d'Aristote et situe dans un cadre socio-politique et dans la tradition morale classique. MacIntyre ne fait pas que répéter, il se situe lui-même dans cette tradition vivante. S'il tient au paradigme moral d'Aristote, il veut en renouveler l'assise en remplaçant la biologie métaphysique par une téléologie sociale. Pour lui, la vertu se comprend dans son insertion dans trois unités progressives de sens et de valeur: les pratiques, l'unité narrative d'une vie, leur inscription dans une tradition morale qui les porte. Nous évaluons la proposition de Maclntyre sur deux points nevralgiques: le remplacement de la téléologie d'Aristote; le concept aristotélicien de vertu. Avons-nous là, sur la morale et sur la vertu, la bonne ré-actualisation d'Aristote et de la tradition qui porte son nom?

Structure and reactivity of silica-supported vanadium and vanadium/titanium single-site catalysts.
Creators: name: Rice, Gordon L.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1999
Subjects: subject: Chemistry, Inorganic.

description: This thesis has been divided into three major sections. The first section deals with the preparation and characterization of silica-supported vanadium(V) complexes. The reactions of O=VX3, X = Cl or OiPr, with the surface of partially dehydroxylated silica gives a single well-defined surface complex, ≡SiOVOX2. These complexes have been characterized by 51V magic angle spinning and 13C cross-polarization magic angle spinning NMR spectroscopy and infrared spectroscopy. The incorporation of 18O labels into specific positions of the silica-supported vanadium complexes has been achieved. When the hydroxyl groups are first exchanged with H218O, the subsequent reaction with O=VX 3 gives exclusively ≡SI18OV16OX 2. Reaction of 18O=VCl3 with unlabelled silica gives only ≡Si16OV18OCl2. The surface complexes undergo clean ligand replacement without displacing or diluting the isotope labels. Other reactions are investigated which are analogous to molecular vanadium reactions and relevant to the understanding of mechanisms in heterogeneous catalysis. The second section deals with a special type of reactivity of silica-supported vanadium(V) complexes. A nonhydrolytic low-temperature route to ternary V-Ti-Si catalysts has been developed. Ti(OiPr)4 migrates underneath the silica-supported vanadium overlayer to give a heterobinuclear complex containing one Ti per V, bound to the silica surface via Si-O-Ti linkages. When Ti(OiPr)4 reacts with the surface of partially dehydroxylated silica, a dinuclear species is formed. Because of this reaction it was not possible to form the mixed Ti-V species by depositing the Ti first. However once a method was developed for the formation of mononuclear silica-supported titanium complexes, we demonstrate that indeed the heterobinuclear species can also be formed by the reaction of O=V(OiPr)3 with ≡SiOTi(OiPr)3. Although there is precedence in the literature for nonhydrolytic condensation of metal chloride alkoxides, this is the first example of such a stoichiometric reaction on a surface. The last part of this thesis deals with the study of silica-supported organovanadium species. The reaction of V(CH2SiMe3) 4 with the surface of partially dehydroxylated silica gives exclusively (≡SiO)2V(CH2SiMe3)2. This surface complex undergoes a surprisingly clean thermal transformation to generate a supported alkylidene complex, (≡SiO)2V=CHSiMe3, with concurrent liberation of SiMe4. The reaction is quantitative and kinetically first order. The mechanism is believed to be a surface assisted alpha-H elimination. The unusual supported vanadium alkylidene reacts with olefins in the absence of alkylaluminum cocatalysts.
Genes required for normal neuronal morphology in Caenorhabditis elegans

description: png-1 encodes the Caenorhabditis elegans homolog of Peptide: N-glycanase, a highly conserved cytosolic enzyme that cleaves N-glycans from misfolded glycoproteins. png-1 was found to regulate several aspects of neuronal morphology including axon branching. In this study, we show that mutations in the NDR kinase pathway genes sax-1 and sax-2 result in png-1 like phenotypes, including excessive branching and ectopic neurites. Furthermore, we found that png-1; sax-1; and png-1; sax-2 double mutants display enhanced defects compared to single mutants, suggesting that png-1 and sax-1/sax-2 act in parallel pathways to restrict axon and branch overgrowth. These interactions suggested a sax-1 enhancer screen as a means to identify additional genes in the png-1 pathway as enhancer mutants should phenocopy png-1 and enhance sax-1 branching defects. This approach recovered at least three sax-1 enhancers ( sens) that act like png-1 to limit axon growth and branching. The identification of these genes should provide new insight into how PNG-1 regulates neuronal morphology.

description: Ultramafic and mafic mine tailings are a valuable feedstock for carbon mineralization that should be used to offset carbon emissions generated by the mining industry. Although passive carbonation is occurring at the abandoned Clinton Creek asbestos mine, and the active Diavik diamond and Mount Keith nickel mines, there remains untapped potential for sequestering CO₂ within these mine wastes. There is the potential to accelerate carbonation to create economically viable, large-scale CO₂ fixation technologies that can operate at near-surface temperature and atmospheric pressure. We review several relevant acceleration strategies including: bioleaching of magnesium silicates; increasing the supply of CO₂ via heterotrophic oxidation of waste organics; and biologically induced carbonate precipitation, as well as enhancing passive carbonation through tailings management practices and use of CO₂ point sources. Scenarios for pilot scale projects are proposed with the aim of moving towards carbon-neutral mines. A financial incentive is necessary to encourage the development of these strategies. We recommend the use of a dynamic real options pricing approach, instead of traditional discounted cash-flow approaches, because it reflects the inherent value in managerial flexibility to adapt and capitalize on favorable future opportunities in the highly volatile carbon market.

description: Cette thèse est une réflexion inspirée de mon expérience personnelle. Ce texte retrace le parcours créatif de deux œuvres scéniques contemporaines destinées à des publics situés aux deux extrémités de l’enfance : les 0-3 ans et les adolescents. En s’appuyant sur la définition de l’expérience esthétique de Jean-Marie Schaeffer, une analyse scénique et dramaturgique de ces réalisations met à jour les stratégies des artistes pour capter l’attention de ces publics et leur faire vivre une expérience cognitive et affective significative. Les œuvres complexes et interdisciplinaires et la qualité de leur mise en relation avec les publics choisis sont les plus susceptibles d’offrir les conditions à une expérience esthétique mémorable. L’intensité de l’expérience dépend aussi de la condition du récepteur, de sa curiosité, de son ouverture pour accueillir l’autre, la nouveauté, l’étrange, tout ce qui diffère de ses croyances et qui va au-delà de ses connaissances immédiates. Une expérience esthétique peut modifier l’organisation des schèmes mentaux, innés ou acquis, et mettre en marche une réflexion sur soi et le monde dans lequel on vit. Schaeffer nous rappelle que l’enfance est un temps particulièrement propice à vivre une expérience esthétique qui est celle d’une relation avec un ou des objets réunis dans un cadre particulier, un moment unique qui suspend le temps dans une attention exacerbée et suscite un état de pleine conscience. Respecter l’intelligence des enfants, c’est leur donner accès à plus grand qu’eux.

Meaning-Making from Literature

description: This research investigated Punjabi children’s meaning-making processes as they engaged with culturally relevant literature, and presents a critical evaluation of Punjabi and Sikh representation in children’s literature. The Punjabi community in Canada is growing rapidly, with Punjabi being the third most commonly spoken non-official language in Canada. Yet, this minority group remains underrepresented in educational research. Past research has shown the numerous benefits minority children experience when engaging with literature that authentically represents their cultural background (see Cunard, 1996; Goldblatt, 1999; Goo, 2018; Steiner, Nash & Chase, 2008; Zhang & Morrison, 2010). This study gave Punjabi children the opportunity to interact with culturally-relevant stories in multimodal ways, and express their understandings through multiple literacies. The children constructed and shared meanings through verbal discussions, multimodal artwork and the inclusion of movement and dramatizations. They drew on a variety of lived experiences to make meaning from the stories. Their meaning-making processes were further enhanced by the collaborative experience of reading, constructing and sharing meanings. This study opens the door to future research into ways of using literature to foster engagement in the classroom and support children’s meaning-making processes.
The twists and turns of a timeless puppet: Violence and the translation and adaptation of Carlo Collodi's "Le avventure di Pinocchio"

description: This thesis explores two English translations of Carlo Collodi's Le avventure di Pinocchio (1883), one by British translator M. A. Murray in 1891 and the other by American translator Walter S. Cramp in 1904. It also examines Walt Disney's adaptation of Pinocchio (1940) for the screen, and in the process studies how the different English target cultures and systems have motivated and influenced translators' and adaptors' decisions and how, therefore, translations and adaptations are necessarily products of their environment. My approach is to focus specifically on moments of violence in Collodi's text, and use them as particularly 'hot' text situations from which to study the English translations. These translations are placed into and then analysed in regard to their respective reconstructed socio-cultural, literary and translation contexts. The norms governing the British and American translators' and American adaptor's respective versions provide some insight into the translators' and adaptor's approach to violence in children's literature and help identify possible reasons for the differences between the source and the target texts, and also between the different translations. Skopostheorie, Descriptive Translation Studies, polysystem theory and norm theory all play a role in the analyses.
The distribution of lightning-caused forest fires in Quebec: 1978-1992.
Creators: name: Hurtubise, Paula.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1996
Subjects: subject: Physical Geography.

description: This study is more in the nature of "exploratory" than "confirmatory" in its exploration of the temporal and spatial patterns of lightning-caused forest fires in Quebec, for the fifteen year period 1978 to 1992. Economic returns garnered from forest products, as well as species and habitat loss, make lightning-caused forest fires an important area for investigation. Natural forest fires are affected by many factors. For the purposes of this study two classes of variables are used in the investigation of the location and timing of lightning forest fires; these are species and weather data. The species data is gathered at the zone forest level and forest age is used at a mature or young level. Weather variables are limited to temperature, precipitation and thunderstorms. These are selected as a result of agreement in related literature that they are valid variables to work with. Lightning-caused fires are mapped at various temporal scales and these are compared with the species and weather data. The study reveals a dichotomous relationship, where fuel characteristics, or forest species, determine the location of fires (or spatial component), and weather dominates the temporal component. Finally, an attempt was made to make generalisations based on the findings so as to identify issues for further research. Understanding the mechanisms which drive the occurrence and distribution of lightning-caused forest fires, is one of the first steps in creating lightning-caused forest fire models.

description: Background: Screening for acute stress is not part of routine trauma care owing in part to high variability of acute stress symptoms in identifying later onset of posttraumatic stress disorder (PTSD). The objective of this pilot study was to assess the sensitivity, specificity, and power to predict onset of PTSD symptoms at 1 and 4 months using a routine screening program in comparison to current ad hoc referral practice. Methods Prospective cross-sectional observational study of a sample of hospitalized trauma patients over a four-month period from a level-I hospital in Canada. Baseline assessments of acute stress (ASD) and subsyndromal ASD (SASD) were measured using the Stanford Acute Stress Reaction Questionnaire (SASRQ). In-hospital psychiatric consultations were identified from patient discharge summaries. PTSD symptoms were measured using the PTSD Checklist-Specific (PCL-S). Post-discharge health status and health services utilization surveys were also collected. Results Routine screening using the ASD (0.43) and SASD (0.64) diagnoses were more sensitive to PTSD symptoms at one month in comparison to ad hoc referral (0.14) and also at four months (0.17, 0.33 versus 0.17). Ad hoc referral had greater positive predictive power in identifying PTSD caseness at 1 month (0.50) in comparison to the ASD (0.46) and SASD (0.43) diagnoses and also at 4 months (0.67 versus 0.25 and 0.29). Conclusions Ad hoc psychiatric referral process for acute stress is a more conservative approach than employing routine screening for identifying persons who are at risk of psychological morbidity following injury. Despite known limitations of available measures, routine patient screening would increase identification of trauma survivors at risk of mental health sequelae and better position trauma centers to respond to the circumstances that affect mental health during recovery.

The effect of piscivorous fish stocking on the planktivorous fish, zooplankton, and phytoplankton communities of 31 southeastern Ontario lakes.
Creators: name: Wilson, Andrew Stewart.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1996
Subjects: subject: Biology, Ecology.

description: Over the past 15 years a great deal of literature has been generated in an attempt to understand the regulation of trophic level biomass and size structure in aquatic systems. I tested the hypotheses that the among-lake variability in biomass and size structure of planktivorous fish, zooplankton, and phytoplankton communities depends on: (1) resource availability (bottom-up processes); (2) piscivorous sport fish stocking (top-down processes); and (3) the particular species of piscivorous sport fish stocked. We sampled 31 lakes in southeastern Ontario over the summers of 1993 and 1994 to obtain indices of abundance, biomass, and size structure of the planktivorous fish, zooplankton, and phytoplankton communities. Seven of the lakes were not stocked and the remaining 24 had stocking intensities ranging from 30 to 1500 individuals stocked per hectare over the 6 years prior to sampling. For both bottom-up and top-down analyses, trophic interactions were strongest at the base of the food web and weakened at higher levels, becoming non-significant thereafter. From these results I conclude that: (1) piscivorous sport fish stocking as a whole (at least at the magnitude examined here) had no effect on planktivorous fish, zooplankton, and phytoplankton biomass or size structure; (2) rainbow trout (Oncorhynchus mykiss) stocked lakes differ at the zooplankton and phytoplankton level from lakes stocked with other species of piscivore; (3) trophic interactions are most evident at the base of the food web (at the zooplankton and phytoplankton level); and (4) resource control (especially total phosphorus) of biomass and size structure in aquatic communities is much more important than consumer control, and it is limited to the phytoplankton and zooplankton. Our results suggest that stocking with piscivorous fish (as practised for sport fishing purposes) does not effectively manipulate plankton abundance. (Abstract shortened by UMI.)

Characterisation and performance prediction of narrowband MIMO channels

Subjects: subject: Engineering, Electronics and Electrical.

description: Wireless communication using multiple-input multiple-output (MIMO) technology enables increased spectral efficiency. The successful deployment of commercial MIMO systems requires a strong understanding of the channel conditions to achieve desired BER performance. A simple channel model that is frequently used in MIMO research assumes i.i.d. complex Gaussian distributed channel gains to describe the channel links. However, this model ignores common propagation effects present in outdoor environments. On the other hand, the wireless channel is very complex to describe using closed-form expressions. The objective of the work presented in this thesis is to parameterise the wireless channel using metrics and use these to predict the bit-error rate (BER) performance for different simulated MIMO techniques. The data measurements were obtained in Ottawa, Ontario at approximately 2 GHz, using the CRC MIMO testbed. Communications systems employing spatial multiplexing or space-time block coding (STBC) are mainly designed for operation under ideal channel characteristics. We consider (1) Vertical-Bell Labs Layered Space-Time (V-BLAST) architecture and (2) a QPSK-based quasi-orthogonal STBC. The measured data exhibit different location-specific characteristics. In some regions, the spatial correlation is low resulting in high diversity and high available mutual information. In others, spatial correlation is higher. Of all the metrics considered, we have identified six that provide useful information to describe the wireless channel. These include effective channel rank, correlation and diversity. The impact of signal power has also been investigated. It has been found that the performance spatial multiplexing is dominantly dependent on the smallest eigenvalue of the spatial correlation matrix. It is not, however, as useful in predicting the performance of STBC. Spatial correlations appear to improve the BER performance of STBC by improving the effective average SNR. It is important to note this trend is opposite to that found in spatial multiplexing. The largest eigenvalue also appears to have an impact on STBC performance. Also, it is shown that mutual information is sufficient enough to describe channel behaviour. These metrics give insight into the dominant propagation mechanisms in the environment and demonstrate the effectiveness of this kind of measurements in characterising the behaviour of the mobile radio channel.

description: Statement of the problem. Physical activity levels generally decrease during adolescence and adulthood. A better understanding of patterns and determinants of physical activity through adolescence can inform physical activity interventions aimed at youth. Methods of investigation. Subjects were 1206 Montreal adolescents followed over 4.5 years. Physical activity was measured using a modified Weekly Activity Checklist. Trajectories were identified using the multilevel model for change. Demographic, psychological, and behavioural predictors were explored separately by sex. Results. A cubic trajectory controlling for season emerged. Activity peaked at age 13.5, decreased, and increased again at age 16.5, but showed significant heterogeneity both within- and between-subjects. Males had higher physical activity levels than females at all ages. Depression, stress, sedentary behaviours, and alcohol use affected physical activity trajectories. Conclusion. Physical activity levels follow a complex, curvilinear pattern during adolescence, and begin to decrease by age 14. Physical activity promotion interventions should focus toward this age group to promote increased physical activity participation.

description: The data from nine permafrost thermal monitoring sites at widely separated locations across northern Canada were examined individually, spatially, and temporally. Three sites are in Nunavut (Alert, Iqaluit, and Baker Lake), two in the Northwest Territories (Table Mountain and Wrigley), and four in the Yukon Territory (Wolf Creek, Sixty Mile, Alpine Burwash, and Red Creek). The sites have between one and five boreholes that are instrumented to between 3 and 60 m with records of varying durations. Most of the boreholes are co-located with weather stations recording air temperatures and snow depths. A comprehensive analysis of each site is presented assessing the relations between climate and permafrost temperatures, both in the near surface and at depth. The local characteristics at each site, and among sites, were assessed using various methods including mean annual temperatures, surface and thermal offsets, n-factors, and the apparent thermal diffusivity. Time series analyses were conducted at sites with longer air and ground temperature data records. Regional mean annual air temperatures were defined as the primary determinant of permafrost temperatures at the study sites, but this relationship is modulated by snow (depth, duration, and timing) and vegetation characteristics, the substrate material, and the moisture content, both frozen and unfrozen, within the active layer and the permafrost. Of the study sites, permafrost temperatures at Iqaluit are the most sensitive to changes in climate due to little buffering between the air and the permafrost, and permafrost temperatures at Wrigley, Table Mountain, and Wolf Creek are the least sensitive to changes in climate due to the significant latent heat effects in this isothermal permafrost associated with high amounts of ice and unfrozen moisture. Climatic cooling was observed in the earlier part of the record at Iqaluit from the late 1940's until the early 1990's, and at Alert between the early 1950's and the mid 1970's. Climatic warming was observed in mean annual and winter average temperatures at Alert, Baker Lake, Iqaluit, Table Mountain, and Wrigley in recent decades. This was reflected in warming permafrost temperatures at all of the long-term thermal monitoring sites. The greatest magnitude of ground temperature warming occurred at Iqaluit (+1.6 to +1.9°C/decade), then Alert (+0.2 to +0.6°C/decade), and Baker Lake (+0.3°C/decade). Ground temperatures at Table Mountain warmed the least (+0.1 to +0.2°C/decade), but the warming at this site is important because it represents a progressive change in unfrozen moisture in the fine-grained, ice rich permafrost.
Development of the tandem oxy-CopeClaisenene reaction: Mechanistic insights and application towards the synthesis of Wiedemannic acid and LL-S491beta

description: This thesis explores the tandem oxy-Cope/Claisen/ene reaction and its application towards the total synthesis of two natural products, wiedemannic acid and LL-S491beta. Drawing on earlier studies carried out on the oxy-Cope/ene rearrangement, the oxy-Cope/Claisen/ene reaction adds to the previous methodology by allowing for the formation of highly functionalized decalin cores bearing up to four contiguous stereocentres, including two adjacent quaternary carbons. The scaffolds accessed by this new tandem pericyclic cascade allow for an easy foray into the synthesis of numerous diterpenoid natural products. The first part of this study focuses on the development of the oxy-Cope/Claisen/ene reaction with respect to both its scope and diastereoselectivity. A combination of experimental methods and theoretical studies allow for the origins of the observed diastereoselectivity to be unveiled. Through the use of judicious substituent selection and/or the addition of remote stereocentres for conformational control, the selectivity of this cascade reaction is effectively controlled. Armed with a highly efficient and stereoselective method for the preparation of functionalized decalin cores, the second part of this study centres on the application of this method to total synthesis. The preparation of a wiedemannic acid analogue is successfully completed with four of its five adjoining stereocentres being effectively set during the key oxy-Cope/Claisen/ene reaction. Owing to a discrepancy in the reported structure of wiedemannic acid however, the synthesis of the natural product is not further pursued. Rather, a new target is chosen. Several innovative routes towards the synthesis of LL-S491beta are described, each relying on the key tandem reaction cascade to build the core of its pimarane skeleton. Finally, the last section of this work addresses some of the novel chemistry discovered along the way including a unique ruthenium-mediated lactonization reaction and an enolate isomerization pathway during the oxy-Cope/ene reaction.

description: This doctoral thesis assesses the impacts of the price policy that aims to set a price for carbon in Canada and analyzes the effects of an emissions cap on the welfare of the current and future generations and energy input substitution. In Essay One, a four-stage game is modeled to formulate the price policy and study its impacts. The main result is that through lobbying activities, the dirty-good sector induces the government to implement a price policy of a carbon that is lower than the expected price of carbon. The consequence of the policy is a transfer of income from the owners of the specific factor used in the production of the clean good and workers to the owners of specific factor used in the production of the dirty good. In Essay Two, an overlapping-generations model is developed to study the impacts of the climate-change policy on the welfare of the current and future generations, the dynamic path of energy and permit prices, and resource substitution. The analysis shows that intergenerational equity issue arises when the oil input is large and when polluters are free to discharge greenhouse gases into the atmosphere. On the equity ground, this result justifies government intervention. The analysis also shows that the use of renewable energy can be introduced quickly if the government implements a stringent policy on climate change. In addition, the process of resource substitution---renewable energy for fossil fuels---is a gradual process and takes place in three stages. The economy will be completely sustained by renewable energy after the stock of fossil fuels is depleted. The one-country model of Essay Two is extended into a two-country world, which is also subjected to a climate-change policy under the form of a global cap on greenhouse gases emissions. It is assumed that the emissions permits are allocated to each country according to its population and that the population of the South is higher than that of the North. The analysis shows that the North will import emissions permits and export the consumption good to pay for these permits.
Martin Heidegger and Jean-Luc Nancy on Community

Subjects: subject: Philosophy.

description: This project will be an examination of the concept of community as it relates to ethics in the works of Martin Heidegger and Jean-Luc Nancy. I will examine Heidegger's thought concerning community and ethics, then the reception of that thought in the secondary literature. I will then examine Nancy's thought concerning community and ethics and his thought's reception in the secondary literature. The critical portion of this project will be an evaluation of Nancy's critical relationship with Heidegger's thought. I will clarify and defend Nancy's arguments against Heidegger's thought. I will also support solution that Nancy proposes. Finally, I will attempt to resolve a criticism commonly launched against Nancy: that his thought fails to engage concrete politics precisely where is must. I will argue that Nancy's thought does indeed engage the concrete by encouraging the development of a praxis, comportment or lifestyle amongst its recipients. Nancy's thought engages us in a dialogue. This dialogue is something which can, and does, continue outside of our relationship with the texts we read, potentially affecting the way we relate to others in our everyday lives.
