Full textAbstract:
Trends in relative sea-level change, shown by curves drawn from drill core and outcrop sections in Llandoverian carbonates of the Hudson Bay Platform, were used to correlate individual parasequences among widely separated localities. Two sequences, bounded by regional disconformities, include: (1) the Severn River Formation, and (2) the Ekwan River, Attawapiskat, and Kenogami River Formations. Initial onlap of marine facies at the base of the Severn River Formation progressed from north to south, occurring first in the Hudson Bay Basin, then in the Moose River Basin; final retreat of the seas at the end of Attawapiskat time was in the opposite direction. The most extensive inundations occurred during Ekwan River and Attawapiskat depositional times. Large-scale trends in the curves delineate four major Early Silurian sea-level highstands also recognized in other basins.Reefs in outcrops along the Attawapiskat River represent one interval of reef growth, had a syndepositional relief of 8-10 meters, and were terminated by a relative sea-level fall. Their present distribution is controlled by variously uplifted fault blocks.
The most important diagenetic processes were early marine cementation and shallow burial diagenesis, and in the southwestern Moose River Basin early secondary dolomitization.

Full textAbstract:
I will argue in this thesis that W.H. Hudson's fiction and non-fiction share the same symbolic substructure: that of the elusive Paradise. Through attention to the concrete details of the world, in certain moments at least, Hudson apprehends an invisible or supernatural dimension. These moments might appropriately be termed epiphanic. What I shall call 'affirmative' epiphany affirms the earthly by revealing the divine through or within it; it is either directly paradisiac, or assimilable to a vision of the earthly Paradise. In contrast to the 'affirmative' epiphany, there is also 'negative' epiphany which opens up a chasm of terror and dread. Violence, affliction, and human submersion in evil are amongst the things that play into the notion of 'negative' epiphany. I will also show that, in Hudson's fiction, there are indications that evil is written into the network of chance and natural law; so that the 'darkness' or evil disclosed by 'negative' epiphany can be seen as ontologically prior to the actions of the human will. The paradisial endures as a fractured and elusive subject of experience, constantly threatened by contingency, violence, or evil. I will also show how, for Hudson, rationalistic and mechanistic ideologies (especially Darwinism) are an obstacle to consistent belief in the spiritual. In this thesis I will attempt to redress the tendency to concentrate on Hudson first and foremost as a nature writer by giving priority to his fiction, which develops the mythopoeic or symbolic aspects of his vision to a greater extent and, I will argue, for this reason involves a deeper or more profound expression of that vision. In Part One I will be using examples from his non-fiction in my examination of his fundamental concerns; in Part Two I will show how these concerns are developed at a greater depth in his fiction.

Thesis, McGill University, 1990. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=74610.
Full textAbstract:
The vital rates of beluga, Delphinapterus leucas, harvested in northern Quebec are within the range reported by previous studies in Alaska and the Canadian and Soviet Arctic. Small sample size and inadequate estimates of survivorship rates prevent meaningful calculation of population growth rate. The pattern of changes in vital rates over the life cycle of beluga and analysis of errors associated with stage classification indicate that the demographic information in a 6 x 6 age-grouped Lefkovitch matrix is similar to that in a 38 x 38 age class Leslie matrix. A 3 stage, length-based model composed of newborns, juveniles and adults contains less demographic information than the larger matrices, but is superior to a juvenile/adult classification scheme. The 3 stage model applied to length frequency data from aerial photographic censuses should provide an alternate method of demographic analysis when harvests are small or absent. Colour is a poor criterion for stage classification.Sensitivity analysis of fecundity and survivorship indicates that survival of gray animals (older juveniles and early breeders) has the most influence on population growth rate. Changes in fecundity have little effect on growth rate. The high sensitivity of population growth rate to juvenile and early adult survival demonstrates that these estimates should be improved if more precise knowledge of beluga demography is required for management purposes.
The age-length data used to evaluate errors associated with stage classification indicate that belugas in Hudson Bay are smaller than those elsewhere, but not to the large degree previously reported. Beluga in estuaries are represented by all size classes. Examination of the integumentary heat loss show beluga and narwhal, Monodon monoceros, to be equally insulated, but only belugas frequent warmer estuarine waters.

Full textAbstract:
This research project investigates the pedagogy of Tom Hudson and his vision for art education. A critical overview of the relationship between Hudson’s pedagogical theory and practice is made, as well as a review of the influences and contexts that shaped the development of his ideas. Having played a significant role in the formation and progress of the Basic Design Movement, Hudson’s practice and ideas are considered and compared with respect to this period and the work of other protagonists, namely Harry Thubron, Victor Pasmore and Richard Hamilton. Hudson’s development of what essentially emerged from this has been investigated, providing an extensive review of what became known as the Foundation course through to Hudson’s retirement in 1987. Contemporary practices have also been considered and observed in order to gain an understanding of current debates and the place of Hudson’s pedagogical views within these. Familiar elements in his writing show that his ideas have relevance to current concerns and practices. Twenty-five years later we are still working to prove that ‘creative activity is more than a mere cultural frill’ (Hudson, 1979, BH/TH/PL/196, p. 2). The study includes a consideration of the archive as a theoretical framework for the artist educator’s research. A substantial amount of primary material for this research has been found within the National Arts Education Archive (NAEA@ysp), a valuable resource with much to offer the art and design educationalist, student or researcher.

Weller, Derek James. "A large late-glacial eruption of the Hudson Volcano, Southern Chile." Thesis, University of Colorado at Boulder, 2015. http://pqdtopen.proquest.com/#viewpdf?dispub=1590001.
Full textAbstract:
Lakes formed in the Aysén region of southern Chile after the retreat of mountain glaciers, beginning by at least ~17,900 cal yrs BP, contain numerous late-glacial and Holocene tephra layers derived from >70 eruptions of the volcanoes in the region, including Hudson, the southernmost in the Andean Southern Volcanic Zone (SVZ). Sediment cores from six of these lakes each contain an unusually thick late-glacial age tephra layer, which based on its distribution and bulk trace-element composition was derived from a large explosive eruption of the Hudson volcano between 17,300 and 17,440 cal yrs BP, and is termed Ho. In these cores, located ~100 km northeast of Hudson, the Ho tephra layers range between 35 to 88 cm in thickness. Comparison with three previously documented large explosive Holocene Hudson eruptions (H1, H2, H3 1991 AD) suggests that Ho was larger, with an estimated tephra volume of >20 km3, the largest post-glacial eruption documented for any volcano in the southern Andes. In total, Hudson has erupted ≥45 km3 of pyroclastic material in the last ~17,500 years, making it the most active volcano in the southern Andes in terms of the total volume of pyroclastic material erupted since the beginning of deglaciation in the region. Chemical stratification is not seen in the Ho deposits, but this eruption was bi-modal, with a much greater proportion of dark glassy basaltic-andesite dense fragments and pumice, which range between 55 to 59 wt % SiO2, and volumetrically less significant lighter colored dacite pumice with 66 wt % SiO2. In contrast, H1 was andesitic in composition, H2 was more felsic than H1, being composed essentially of dacite, and although H3 in 1991 AD was again bi-modal, it erupted a much smaller proportion of mafic compared to felsic material than Ho. Thus, the repetitive large explosive eruptions of Hudson volcano have evolved to progressively less mafic overall compositions from late-glacial to historic times, and their volumes have decreased. All analyzed phases of different Hudson eruptions, have similar Sr-isotopic composition (0.70444 ± 0.00007), indicating that crystal-liquid fractionation rather than crustal assimilation was the main process responsible for these chemical variations.

Full textAbstract:
In part 1, the spatial and temporal relationships between subarctic Canadian sea-ice cover and atmospheric forcing are investigated by analyzing sea-ice concentration, sea-level pressure, and surface air temperature, as well as ice thickness, runoff, and sea surface temperature, from 1953-1988. The sea-ice anomalies in Hudson Bay, Baffin Bay and the Labrador Sea are found to be related to the North Atlantic Oscillation (NAO) and the Southern Oscillation (SO). From the application of a spatial Student's t-test and a Monte Carlo simulation, we found that sea ice responds significantly to the SO event only in summer, and to the NAO event only in winter.A spectral analysis shows that sea-ice cover in Baffin Bay and the Labrador Sea responds to the SO and SAT fluctuations at about 1.7 year, 3-5 year and about 8-10 year periods. In addition, a sea-ice signature associated with the so-called "climate jump" during the early 1960s was found. The ice thickness and ice-melt date data are also used to verify the above findings.
In part 2, the three-dimensional ocean general circulation model of Blumberg and Mellor (1983, 87) was used to simulate the winter and summer ocean circulation in Hudson Bay under specified atmospheric forcing and runoff. This model uses vertical sigma coordinates and horizontal orthogonal curvilinear coordinates. The vertical viscosity and diffusivity are computed using the Mellor-Yamada (1982) second-order (2.5) turbulence closure, while the values for similar horizontal parameters are calculated using the Smagorinsky (1963) parameterization. The new version of this model uses the semi-implicit scheme for the shallow water equations (Casulli, 1990). A consistent, modified radiation boundary condition has been developed for the surface elevation and the normal barotropic velocity for the universal multi-level, baroclinic model with strong vertical stratification. The surface cyclonic circulation in summer and winter, due in part to the boundary inflow from Roes Welcome Sound to the northwest of the domain, has been well simulated.
In part 3, a dynamic thermodynamic model of sea ice with viscous-plastic rheology (Hibler, 1979; 1980) is used to simulate the seasonal cycle of sea-ice motion, thickness, compactness, and growth rate in Hudson Bay under monthly climatological atmospheric forcing. The simulated results for ice cover in other seasons also compare favourably with the observed climatology and with measurements from satellites. In particular, the model gives complete sea-ice cover in winter and ice-free conditions in late summer. (Abstract shortened by UMI.)

Cao, Maggie M. "Episodes at the End of Landscape: Hudson River School to American Modernism." Thesis, Harvard University, 2014. http://dissertations.umi.com/gsas.harvard:11535.
Full textAbstract:
This dissertation examines the dissolution of landscape painting as a major cultural project in the late nineteenth-century United States. As a genre aligned with the goals of nation building, landscape maintained a privileged artistic status for much of the nineteenth century. Yet as frontier development, land speculation, environmental change, and other factors slowly rendered its conventions meaningless, landscape became the site through which American artists most urgently sought to come to terms with the modern world. This argument is anchored by unorthodox artworks, from landscapes resembling banknotes to paintings made out of bird feathers—limit cases that allude to the failure of landscape in sustaining American cultural goals. Chapter One concerns Albert Bierstadt's aesthetic struggles in post-frontier America. During the 1890s, Bierstadt's anxieties about landscape surfaced in the particularities of objects that fold and unfold, from butterflies painted by chance to expanding railway cars—objects that might be considered the subconscious of a genre built upon expansionist ideology. Chapter Two argues that Martin Johnson Heade's tropical and marsh paintings of the 1870s and 1880s used “groundless” conditions to express cultural insecurities about traversable land and its representation. The pictorial blockages and interferences in Heade's paintings challenge both the compositional legibility espoused in the blockbuster canvases of his mentor and rival Frederic Church and the physical accessibility promised by the period's environmental interventions. Chapter Three proposes that Ralph Blakelock's nocturnes and money paintings—produced in the context of rampant land speculation, volatile art markets, and representational doubts surrounding paper currency—attempt but fail to overcome landscape's monetary entanglements. Blakelock's paintings theorize the value of labor and material accumulation in the increasingly abstract economic world of the last decades of the nineteenth century. Chapter Four reconsiders the trope of the "figure in the landscape" using Abbott Thayer's turn-of-the-century representations of animal camouflage. In these mixed-media artworks, Thayer's attempts to visualize invisibility demonstrate the ways in which camouflage proved irreconcilable with landscape's figure-ground principles. Together, these episodes trace pictorial attempts to resolve spatial problems arising with modernity, and in so doing, they signal a shift toward new paradigms of representation.History of Art and Architecture

Polyethylene devices (PEDs), which rely on the partitioning of hydrophobic organic contaminants (HOCs) between water and polyethylene, were shown to be useful for the measurement of dissolved HOCs like polycyclic aromatic hydrocarbons (PAHs) in natural waters. These PEDs allow for the measurement of the fugacity or "fleeing tendency" of such chemicals in water. These dissolved concentrations are of ecotoxicological concern as they reflect the HOC fraction that is driving uptake by the surrounding organisms. Because PEDs require on the order of days to equilibrate in the field, their use provides time-averaged measurements. Laboratory-measured polyethylene-water partition coefficients for two PAHs were: 17,000 ±1000 (mol/LPE)/(mol/Lw) for phenanthrene and 89,000 ± 6000 (mol/LPE)/(mol/Lw) for pyrene. These organic polymer-water partition coefficients were found to be comparable to other organic solvent-water partitioning coefficients. These large coefficients allowed for the measurement of dissolved concentrations as low as 1 pg/L for benzo(a)pyrene and 400 pg/L for phenanthrene in the lower Hudson Estuary. Sampling performed in the lower Hudson Estuary during neap and spring tides revealed increased concentrations of dissolved pyrene and benzo(a)pyrene, but not phenanthrene, during increased sediment resuspension. These data suggest that resuspension events mostly influence the bed-to-water exchange of PAHs with greater hydrophobicities. PAH water concentrations predicted assuming dissolved and sorbed concentrations related via the product, fomKom, where fom is the fraction of organic matter in the suspended sediments and Kom is the organic-matter-normalized solid-water partition coefficient for the PAH of concern, were far from observed concentrations. Adding the influence of soot to the partition model via Kd = fomKom + fse,4Ke, where fse. is the weight fraction of soot carbon in the solid phase and Ke is the soot carbon-water partition coefficient estimated form activated carbon data, yielded predicted concentrations that were much closer to the observed values when PAH partitioning to soot was included in the partitioning model. This finding suggests that soot plays an important role in controlling the cycling of PAHs in the aquatic environment. However, even when the soot partitioning of PAHs was included in the model, the predicted dissolved values were still larger than the measured values. This suggests that the time of particle resuspension is too short to allow for particle-water sorptive equilibrium. Using ratios of source indicative PAHs, it was estimated that 90% of the dissolved PAH fraction was derived from petrogenic sources. In contrast, the same source ratios for the total (dissolved and sorbed) PAH concentrations indicated that only 55% of the total were petrogenically-derived. The observations in this work suggest that efforts to regulate and remediate PAH-contaminated sediments must consider the potential impacts of soot associations of the PAHs.

Full textAbstract:
There is a growing interest and emphasis on teaching biotechnology methods and concepts to high school level students in order to help prepare them to be able to participate in highly technological careers. Numerous biotechnology professional development programs exist for science teachers to gain knowledge and skills that are necessary to teach biotechnology. While it is an easy transition to teach biotechnology methods in advanced and AP level courses, there is uncertainty about the limitations and accommodations that will be necessary to incorporate biotechnology labs into a regular high school biology classroom with 28 students or more of various levels and exceptionalities. The additional expense and time necessary to incorporate biotechnology are justified if students gain increased conceptual understanding and demonstrate improved attitude toward science as a result of the labs. The primary question I sought to answer with this project was what are the effects of incorporating biotechnology labs on high school students' understanding of molecular biology concepts? Secondary questions related to the project are: What were the effects of incorporating biotechnology labs on students' interest in science, students' confidence in their abilities to do science, and on my teaching practices? The sequence of biotechnology labs that occurred within the curriculum of compulsory high school biology were quantitative protein analysis of food, DNA fingerprinting, pGLO bacterial transformation, and GMO investigation of food. The labs utilized Vernier Probeware and Bio-Rad Explorer kits. Conceptual understanding of molecular biology concepts was assessed using student developed concept maps and free-response questions. Anonymous student surveys and one-on-one student interviews were used to assess attitude toward science, which is defined in this project as interest, confidence, and relevance. Results for improved attitude were inconclusive; however gains in conceptual understanding were substantial with the biotechnology labs.

In a world of excess, people rarely stop to realize their impact on their environments. Our built environment is especially feeling the effect of our irresponsibility, and the solution is only a matter of re-wiring our perceptions of energy usage. Many technologies make it possible to have the impossible, but nobody stops to question whether or not these advances are beneficial. A presumably sustainable system turned out to be one of the most energy wasteful ones in existence. In the complex process of getting food from the field to your house, the best solution is to simplify. Nature will do most of the work; we need to learn to work with it. Current building practices can benefit greatly from this concept, to rethink the existing process by simply cutting out the unneeded steps and using the free energy available to us every day. Our values need to change. Because the corporation controls so much of our daily lives, they are the ones that will bring about the change in consciousness we desperately need. By re-designing Sysco headquarters to do everything that the company claims to do (and currently doesn't), and interact with the public in a new and radical way, not only can we make changes to how we think about the built environment, but we can also start to show that a change in awareness is entirely possible. If we can change the values of those that make the biggest differences in our world, then we've effectively changed an entire populations' way of thinking.

Full textAbstract:
Un territoire est indéniablement associé à Napoléon et à sa légende dans l'esprit des populations. Il ne s'agit pas de la Corse, lieu de naissance, mais bien de Sainte-Hélène, lieu d’exil, de mort mais aussi de construction de la légende napoléonienne. C'est sur cette île de l'Atlantique sud qu'entre 1815 et 1821 celui qui, pendant plus de vingt ans, a fait trembler l'Europe, vit les dernières années de son existence. Le captif pendant toutes les années de sa détention sur Sainte-Hélène n'est peut-être à aucun autre moment de sa vie si étroitement observé. Cependant, les Français, entre 1815 et 1821, ignorent ce qui se passe sur cette île perdue de l’Atlantique sud. Les nouvelles sur ce personnage sont rares sinon absentes et l'absence d'information véridique sur les événements de l'île est considérable. Ce constat est accentué par la situation de Sainte-Hélène. Il s'agit d'un lieu éloigné, inconnu et difficilement compréhensible pour la grandes majorités des Français du XIXe siècle. Cette absence d'information entraine les plus folles rumeurs. Effectivement, les fausses nouvelles parsèment l'exil de Napoléon, des Français répandent des bruits, prétendent connaître la vérité et la transmettre généralement oralement, plus rarement par l'écrit, aux autres. Si les bruits sont essentiellement émis entre 1815 et 1821 ils se poursuivent au cours des années 1820 et même au-delà par de multiples relais.Nombre de bruits et d'ouvrages offrent de multiples histoires toutes plus sensationnelles les unes par rapport aux autres sur l'exil de Napoléon. Parmi elles, Napoléon s'est évadé de Sainte‑Hélène. De véritables faits ont inspiré les nombreuses théories évasionistes qui fleurissent à partir de 1815. Ainsi, des projets d’enlèvement ont indéniablement été pensés. Néanmoins, aucun des plans n’est mis à exécution, amenant en conséquence un questionnement sur les raisons de l’absence de leur concrétisation, n'ont-ils pas simplement été de simples échanges verbaux entre Bonapartistes ?Enfin, les rumeurs perdurent après 1821 en partie grâce aux arts. En effet, l'internement de Napoléon a beaucoup été représenté par la littérature, la peinture et plus récemment par le cinéma. Par exemple, de très nombreux auteurs du XIXe siècle se sont inspirés du séjour de l'Empereur à Sainte-Hélène de façon plus ou moins évidente et ont réinvesti les éléments constitutifs de la légende.Toutes les rumeurs et les représentations artistiques de la captivité déforment les dernières années de Napoléon. Or, ces représentations altérées restent dans la mémoire collective car elles sont plus faciles à retenir, elles sont de meilleures histoires que la réalité... Et donc, la mythologie fini par altérer la réalité historique. Par exemple, l'idée d’un Napoléon humilié en permanence par les Anglais est ancrée dans la mentalité populaire comme parmi les élites. D'ailleurs cette distorsion de la réalité est une partie intégrante de la légende napoléonienne. Sans l'idée du calvaire de Napoléon à Sainte-Hélène prisonnier des puissances de la Sainte-Alliance et l’image négative de Hudson Lowe, la figure du captif auprès des libéraux et des nationalistes au XIXe siècle n’aurait pas été la même. La légende de Sainte-Hélène est donc une partie fondamentale de l’histoire napoléonienneA territory is undeniably associated with Napoleon and his legend in the minds of the peoples. It is not a question of Corsica, place of birth, but of Saint Helena, place of exile, of death but also of construction of the napoleonic legend. It is on this island of the South Atlantic that between 1815 and 1821 he who, during more than twenty years, made tremble Europe, saw the last years of its existence. The captive during all the years of his detention on St. Helena Napoléon is closely observed. However, the French, between 1815 and 1821, do not know what is happening on this lost island of the South Atlantic. News about this character is rare if not absent and the lack of truthful information about the events of the island is considerable. This observation is accentuated by the situation of St. Helena. It is a distant place, unknown and difficult to understand for the great majority of the French of the nineteenth century. This lack of information leads to the wildest rumors. Indeed, the false news strew the exile of Napoleon, French spread noises, claim to know the truth and to transmit it generally orally, more rarely in writing, to others. If the noises are essentially emitted between 1815 and 1821 they continue during the 1820s and even beyond by multiple relays. Many noises and books offer multiple stories all about Napoleon's exile. Among them, Napoleon escaped from Saint Helena. Real facts have inspired the many evasive theories that flourished from 1815. Thus, kidnapping projects have undeniably been thought out. Nevertheless, none of the plans are put into execution, leading consequently a questioning on the reasons of the absence of their concretization. Maybe, they were simple verbal exchanges between Bonapartists? Finally, rumors endure after 1821 partly thanks to the arts. Indeed, the internment of Napoleon was much represented by literature, painting and more recently by cinema. For example, many nineteenth-century writers drew inspiration from the Emperor's stay in Saint Helena in a more or less obvious way and re-invested the constituent elements of the legend. All the rumors and artistic representations of captivity distort the last years of Napoleon. However, these altered representations remain in the collective memory because they are easier to remember, they are better stories than reality ... And so, mythology ended up altering the historical reality. For example, the idea of a Napoleon permanently humiliated by the British is rooted in the popular mentality as among the elites. Moreover this distortion of reality is an integral part of the Napoleonic legend. Without the idea of Napoleon's ordeal on St. Helena prisoner of the Holy Alliance and the negative image of Hudson Lowe, the figure of the captive among liberals and nationalists in the nineteenth century would not have been the same. The legend of St. Helena is therefore a fundamental part of Napoleonic history

Full textAbstract:
L’océan Arctique est une des régions les plus touchées par les changements climatiques. Une importante augmentation de la température de ses eaux de surfaces et des précipitations y est attendue, entrainant une perte significative du couvert de glace et une augmentation des activités humaines. Causant des effets sur les paramètres physico-chimiques, ces changements devraient directement affecter les producteurs primaires (algues de glace et phytoplancton), et de ce fait limiter l’apport de matière organique vers les fonds marins. Il est ainsi admis que les changements climatiques affecteraient la distribution, la diversité et l’abondance des communautés benthiques, en raison de leur impact sur les paramètres environnementaux (couplage pélago-benthique et paramètres physico-chimiques), mais également sur les services et fonctions écosystémiques (par exemple la reminéralisation benthique). La diminution de l’étendue et de l’épaisseur de la glace de mer, la désalinisation des eaux de surface ou bien encore l’augmentation du trafic maritime dans les régions de la Baie d’Hudson et de l’est de l’Arctique Canadien, sont susceptibles d’être à l’origine de grands changements dans la structure des communautés benthiques et des habitats à structures biogéniques. Les impacts des changements climatiques sur les écosystèmes benthiques arctiques étant jusqu’alors peu connus, les objectifs de cette thèse étaient de i) d’apporter une description plus complète et actualisée de la diversité et la distribution spatiale des communautés benthiques dans le complexe de la Baie d’Hudson ; ii) de comprendre les effets des changements climatiques sur la biodiversité et le fonctionnement des écosystèmes benthiques; et iii) d’enrichir les connaissances des écosystèmes benthiques et d’appuyer la désignation de zones d’intérêt écologique et biologique ainsi que des aires marines protégées. Les travaux réalisés pendant cette thèse nous ont permis de i) mettre à jour les données épibenthiques dans le complexe de la Baie d’Hudson ; ii) aider les gestionnaires dans la mise en place de zones d’importance écologique et biologique ainsi que de zones d’intérêts pour une future désignation d’aires marines protégées; et iii) mettre en évidence l’importance des coraux de bambous en milieu profond sur le fonctionnement de l’écosystème benthique. Un total de 380 taxa a été dénombré dans 46 stations à travers le complexe de la Baie d’Hudson. Malgré une relativement faible couverture spatiale de notre échantillonnage, nous avons été en mesure d’estimer que ce recensement représentait 71 % des taxons présents dans le complexe de la Baie d’Hudson. Nous avons montré que la biomasse, l’abondance, la diversité ainsi que la distribution spatiale des communautés épibenthiques étaient fortement influencées par le substrat, la salinité, les ressources alimentaires et la couverture de glace. Nous avons aussi pu démontrer que la faible diversité, abondance et biomasse des communautés observées près des côtes étaient causées par les importants écoulements d’eaux douces. À l’inverse, les données récoltées dans les polynies situées plus au large montrent un fort couplage pélago-benthique se traduisant par une forte productivité en termes de biomasse, d’abondance et de diversité. L’utilisation d’un modèle de distribution des communautés a permis de démontrer l’importance de la présence de glace et indirectement des algues de glace associées à cet habitat sur les communautés épibenthiques occupant le centre de la Baie d’Hudson. La projection des communautés sous un scénario climatique RCP4.5 a révélé que le centre de la Baie ressortait, potentiellement, comme étant la zone la plus vulnérable aux changements climatiques puisqu’une perte de diversité liée à la diminution de la glace de mer est attendue. À l’inverse, les zones côtières pourraient possiblement servir de refuges en augmentant la diversité. En outre, notre étude a montré que la présence des structures biogéniques telles que les coraux bambous, dans les habitats profonds, améliore le piégeage des particules de matière organique menant à une plus forte densité d’espèces endofauniques dans ces milieux comparativement à des sédiments nus. Cet effet a également été constaté dans la reminéralisation benthique où les sédiments des structures biogéniques agissaient comme source de nitrates et d’ammonium. En revanche, nos travaux n’ont pu démontrer ces effets dans un habitat moins profond hébergeant des éponges. En générant de nouvelles connaissances sur la répartition actuelle et future des communautés épibenthiques du complexe de la Baie d’Hudson ainsi que sur le fonctionnement de l’écosystème benthique dans les habitats à structures biogéniques, les résultats de cette thèse contribueront à désigner des zones d’importance écologique et biologique ainsi qu’à la mise en place d’aires marines protégées et de stratégies de conservation de la biodiversité arctique.The Arctic Ocean is emerging as one of the regions that is most affected by climate change. A significant increase in precipitation and sea surface water temperatures are expected and will undeniably lead to a significant loss of sea ice cover. Because of their effects on physicochemical parameters, these changes are expected to directly impact the surface primary producers (sea ice algae and phytoplankton), thereby limiting organic matter input towards the seafloor. It is thus commonly accepted that climate change will affect the distribution, diversity and abundance of benthic communities, due to its impact on environmental parameters (pelagic-benthic coupling and physicochemical parameters), and on ecosystem services and functions (e.g., benthic remineralization). As a consequence, the decrease in sea ice cover, the desalination of the surface layer or the increase in shipping traffic in the Hudson Bay Complex and in the eastern Canadian Arctic will likely lead to major changes in benthic community structure and biogenic structural habitats. In this context and since the impacts of climate change on benthic arctic ecosystems were still poorly understood, the objectives of this thesis were to i) describe the diversity and distribution of epibenthic communities in the Hudson Bay Complex and ii) understand the effects of climate change on biodiversity and benthic ecosystem functioning. The outcomes of this thesis allowed us to i) provide the most recent survey on epibenthic organisms in the Hudson Bay Complex and their relationships with environmental variables; ii) identify diversity hotspots sensitive to climate change; and iii) document and compare benthic biodiversity and fluxes within biogenic structures and adjacent bare sediments in the Canadian Arctic. A total of 380 taxa have been identified from 46 stations sampled across the Hudson Bay Complex. Despite the relatively low spatial coverage of our sampling, we estimated that our survey represented 71% of the taxa present in the Hudson Bay Complex. We showed that biomass, abundance, diversity and spatial distribution of epibenthic communities were strongly influenced by substrate, salinity, food supply and sea ice cover. We also showed that freshwater inputs were responsible for the lowest biomass, abundance and diversity observed along the coasts. In contrast, data collected from polynyas, further offshore, showed strong pelagic-benthic coupling resulting in high productivity in terms of biomass, abundance and diversity. Moreover, hierarchical modelling of species communities highlighted the influence of sea ice and indirectly of sea ice algae on the epibenthic communities occupying the central Hudson Bay. Projections of the structure of epibenthic communities under a RCP4.5 climate scenario revealed that the central Hudson Bay emerges as the most vulnerable area to climate change with a future diversity loss related to the decrease of sea ice. On the contrary, it would appear that coastal areas will serve as refuges and increase the diversity. In addition, our study showed that the presence of biogenic structures in deep habitats improved the trapping of organic matter, leading to a higher density of infauna in these environments compared to bare sediments. Their presence has also been found to enhance sediment nutrient release in the form of nitrates and ammonium. However, our study could not demonstrate these effects in a shallower sponge habitat. By providing new knowledge on the current and future distribution of epibenthic communities in the Hudson Bay Complex and the benthic ecosystem functioning in habitats with biogenic structures, results obtained during this thesis will contribute to the designation of Ecologically and Biologically Significant Areas, as well as to the establishment of Marine Protected Areas and conservation strategies in the Arctic Ocean.

Full textAbstract:
Pressured and ridged ice is a dangerous hazard facing ships in the Arctic. Ships can become stuck or beset in these conditions, which is environmentally and economically costly. Understanding where and when ridges form as a result of pressured ice is important for ensuring safe winter shipping operations; however there have been few studies to date regarding the distribution of ridges and their impacts within a geographic region. The Hudson Strait, which connects Hudson Bay and the Atlantic Ocean, is the site of ongoing winter shipping, where vessels frequently encounter pressured ice. This thesis addresses two questions: where and when do ridges occur in the Hudson Strait and what are their impacts on an ice strengthened vessel traveling through the Strait. To answer the first question, ridges were manually identified in RADARSAT-1 and -2 images during the winter months (December to May) from 1997-2012. Ridge counts and densities for each winter season were calculated and their spatial distribution was mapped. A 30-year sea ice climatology of the Hudson Strait was also created in order to understand ongoing trends in freeze-up and breakup timing in the region. Recurring patterns in the location and timing of ridging were found in the Hudson Strait, specifically in areas where shearing and bottlenecks created pressure. Ridge densities were correlated with sea level pressure, air temperature and wind NCEP reanalysis data to look to for connections between these factors and ridge densities. Some connections were found between freeze-up dates, sea level pressure and ridge densities.
The second half of this thesis focuses on how ridges impact the voyage of an ice-strengthened vessel. Log books from the MV Arctic, a cargo ship that makes two winter transits through the Hudson Strait every year, were used to plot the movement of the ship and where and when it became beset. These data were examined for temporal and spatial patterns in besetting events. Most besetting events took place in February and March. They typically occurred in the eastern and western ends of the Strait. These voyages were compared to ridge data from the first half of thesis, and there were good correlations between the presence of high ridge densities and ship besetting events, demonstrating that ridge densities identified in satellite imagery can act as a proxy when forecasting hazardous ice conditions.
This research fills an important knowledge gap in understanding where and when pressured ice forms in the Hudson Strait and what factors play a role in creating this hazardous ice condition. It also addresses the impacts that ridges have on ship transits through the Strait.

Full textAbstract:
The regional distribution of Holocene sediments of eastern Hudson Bay off the Great Whale River mouth was mapped using a grid of reflection seismic lines over 60 km long and covering an area of approximately 800 km$ sp2$ and data from eight piston cores. A larger data base and a greater area of study than that used in previous studies significantly increases our understanding of the sedimentation and deglaciation processes that have occurred in the area since the last deglaciation. Based on the seismic records and piston cores, four stratigraphic units overlying the Proterozoic bedrock (unit 1) were defined and interpreted: unit 2, glacial till deposited by a westward flowing ice sheet; unit 3, glaciolacustrine stratified muds deposited in glacial Lake Ojibway; unit 4, postglacial marine muds deposited in Tyrell Sea; unit 5, distal fluvio-deltaic sediments from the Great Whale River. Textural and geochemical analyses of individual laminae suggest that unit 3 rhythmites are true varves; dark "summer" laminae were deposited mainly by underflows during the open water season, and light "winter" laminae were deposited by overflows-interflows under a seasonal ice cover. Unit 5 covers approximately 400 km$ sp2$ and occurs as a deltaic constructional wedge which reaches 11 km offshore of the Great Whale River entrance. It was deposited between 3500 BP and 2800 BP from material supplied by the erosion of the Sakami Moraine and of glaciolacustrine and marine muds exposed along the river banks.

Facing disinvestment and unemployment, many places look to culture-based strategies for revitalization. Traditional models of culture-based community revitalization, however, have been criticized for contributing to gentrification, social polarization, and cultural discrimination. Communities seeking to avoid the contradictions of market oriented culture-based revitalization strategies can look to the efforts of community based organizations for models of how culture and the arts can contribute to revitalization without being limited to defining the benefits of their efforts solely in economic terms. In this thesis, I describe the efforts of one arts organization, Time & Space Limited (TSL), as an example of this process. Through an in-depth case study, I describe the role of TSL, a community-based arts organization, in creating an alternative strategy for community revitalization through the arts in Hudson, New York.

ABSTRACT
Using as a springboard a historical overview of Portuguese presence in Canada and the United States, I analyze the current stage of the Portuguese language in Hudson, Massachusetts. Indeed, by looking at how during the past three generations Portuguese has gone from a full-fledged living language spoken by immigrants hailing from Portugal—particularly the island of Santa Maria, Azores—who spoke it as a native tongue, to a Heritage Language (HL), and eventually to a cultural vector whereby its speakers rely on their shared legacy to learn it anew as a L2. The analysis of linguistic samples of the third generation of Portuguese-Americans of Hudson High School will provide a profile of these individuals who do not become speakers of an unknown reality yet they become Portuguese speakers with an Anglophone base and structure. They are therefore speakers of a heritage and culture, but not speakers of the inherited language.

Thesis advisor: Jeremy ShakunThe mechanisms of abrupt climate change during the last glacial period are not yet fully understood. The objective of this research is to use oxygen isotope and magnesium/calcium ratios from foraminifera in a marine sediment core <200 km southeast of New York City (Ocean Drilling Program 174 Site 1073A) to test the hypothesis that changes in freshwater run-off patterns during intermediate extensions of the Laurentide Ice Sheet caused abrupt climate change by disrupting the Atlantic thermohaline circulation. The combination of foraminiferal δ18O and Mg/Ca yields salinity as an isolated variable, which is used as a proxy for Hudson River discharge through ~42,000-28,000 years ago. This thesis reviews the literature on abrupt climate change and compares the Hudson River paleodischarge record to established records of abrupt climate events observed in Greenland ice cores. It concludes that a higher resolution of data points is required to evaluate the impact of Hudson River discharge on abrupt climate change

Full textAbstract:
A model for Wisconsinan glaciation and deglaciation of Hudson Bay is proposed based on depositional facies of the surficial sediments. These facies, defined on the basis of texture, composition, and acoustic character, indicate that sediment distribution is controlled primarily by Late Wisconsin glaciation. Post-glacial sedimentation is restricted to the shallow marine environment (100m deep) and involves reworking of glacially-derived sediments by rivers and/or marine currents. Deposition due to sea-ice rafting is minor. Within the glacigenic sediments, dispersal trends of distinctive lithologies and mineralogies (derived from sources adjacent to and underlying the bay) indicate that (1) western Hudson Bay was glaciated by ice flow eastward from a centre in the District of Keewatin, and (2) the eastern and southern bay was glaciated by ice flow westward from a dispersal centre in Nouveau Quebec. Seafloor geomorphic features and sediment composition suggest that deglaciation was focused at the confluence between these two ice sheets, possibly through ice streaming and calving bay formation. Eastward and southward dispersal of sediment derived from sources within the bay suggest a residual ice mass remained centered over Hudson Bay following glacial maximum. The deglaciation model invokes stabilization of the ice margin in the north, extension of a calving bay in Hudson Strait into west-central Hudson Bay, northward drainage of proglacial lakes along major bathymetric depressions, and, finally, rapid collapse of the ice sheet.

The McTronX research group at the North-West University is currently researching self-sensing techniques for Active Magnetic Bearings (AMB). The research is part of an ongoing effort to expand the knowledge base on AMBs in the School of Electrical, Electronic and Computer Engineering to support industries that make use of the technology. The aim of this project is to develop an integrated co-processor based power electronic drive with the emphasis placed on the ability of the co-processor to execute AMB self-sensing algorithms.
The two primary techniques for implementing self-sensing in AMBs are state estimation and modulation. This research focuses on hardware development to facilitate the implementation of the modulation method. Self-sensing algorithms require concurrent processing power and speed that are well suited to an architecture that combines a digital signal processor (DSP) and a field programmable gate array (FPGA). A comprehensive review of various power amplifier topologies shows that the pulse width modulation (PWM) switching amplifier is best suited for controlling the voltage and current required to drive the AMB coils. Combining DSPs and power electronics to form an integrated co-processor based power electronic drive requires detail attention to aspects of PCB design, including signal integrity and grounding.
A conceptual design is conducted and forms part of the process of compiling a subsystem development specification for the integrated drive, in conjunction with the McTronX Research Group. Component selection criteria, trade-off studies and various circuit simulations serve as the basis for this essential phase of the project. The conceptual design and development specification determines the architecture, functionality and interfaces of the integrated drive. Conceptual designs for the power amplifier, digital controller, electronic supply and mechanical layout of the integrated drive is provided.
A detail design is performed for the power amplifier, digital controller and electronic supply. Issues such as component selection, power supply requirements, thermal design, interfacing of the various circuit elements and PCB design are covered in detail. The output of the detail design is a complete set of circuit diagrams for the integrated controller.
The integrated drive is interfaced with existing AMB hardware and facilitates the successful implementation of two self-sensing techniques. The hardware performance of the integrated coprocessor based power electronic drive is evaluated by means of measurements taken from this experimental self-sensing setup. The co-processor performance is evaluated in terms of resource usage and execution time and performs satisfactorily in this regard.
The integrated co-processor based power electronic drive provided sufficient resources, processing speed and flexibility to accommodate a variety of self-sensing algorithms thus contributing to the research currently underway in the field of AMBs by the McTronX research group at the North-West University.Thesis (M.Ing.

Full textAbstract:
It is common knowledge that invasive species cause worldwide ecological and economic damage, and are nearly impossible to eradicate. However, upon introduction to a novel environment, alien species should be the underdogs: They are present in small numbers, possess low genetic diversity, and have not adapted to the climate and competitors present in the new habitat. So, how are alien species able to invade an environment occupied by native species that have already adapted to the local environment? To discover some answers to this apparent paradox I conducted four ecological genetic studies that utilized the invasive species Brachypodium sylvaticum (Hudson) Beauv. to determine mechanisms contributing to adaptation and success in the novel habitat.
The first study used simulations and experiments to test the hypothesis that genetic purging, the process where genetic load is reduced by selection against the recessive deleterious alleles expressed in the homozygous state, promotes invasive range expansion. I found that homozygous populations on B. sylvaticum's range periphery displayed lower inbreeding depression compared to heterozygous populations near introduction sites. Empirical tests with B. sylvaticum further demonstrate that purging of genetic load is a plausible scenario promoting range expansion during invasion.
Next, I explored how the interaction between population genetic diversity and the environment contributed to the establishment and spread of Brachypodium sylvaticum. I found that nitrogen application increases both final size and shoot biomass for B. sylvaticum individuals from source populations with low HS levels to levels found in individuals from populations with high HS. A coefficient of relative competition intensity index (RCI) displayed reduced effects of interspecific competition on B. sylvaticum biomass in high nitrogen plots. Results show that elevated nitrogen deposition is a factor that increases establishment of introduced species with historically small effective population sizes.
Thirdly, I investigated phenotypic differentiation during the establishment and range expansion of Brachypodium sylvaticum. Utilizing a novel approach, unique alleles were used to determine the genetic probability of contribution from native source regions to invasive regions. These probabilities were integrated into QST-FST comparisons to determine the influence of selection and genetic drift on twelve physiological and anatomical traits associated with drought stress. Phenotypic divergence greater than neutral expectations was found for five traits between native and invasive populations, indicating selective divergence. Results from this study show that the majority of divergence in B. sylvaticum occurred after introduction to the novel environment, but prior to invasive range expansion.
The final chapter of my dissertation investigates the adaptive role of genetic differentiation and plasticity for Brachypodium sylvaticum invasion. Plasticity was measured across treatments of contrasting water availability. Linear and nonlinear selection gradients determined the effect of directional and quadratic selection on plasticity and genetic differentiation. Invasive trait divergence was a consequence of post-introduction selection leading to genetic differentiation, as there were no plastic responses to contrasting water availability for any measured traits. Genetic divergence of invasive plants was not consistently in the direction indicated by selection, suggesting limitations of selection that may be a consequence of physical constraints and/or tradeoffs between growth and abiotic tolerance. Results suggest that selection, rather than plasticity, is driving phenotypic change in the invaded environment.
The combined volume of these studies contributes significantly to the field of invasion and plant biology by providing novel insights into the processes underlying range expansion, adaptation, and ultimately, evolution of introduced species.

Full textAbstract:
This thesis examines the development and validation of Canadian Land Surface Scheme (CLASS) for various wetland landscapes individually, along with an evaluation of modelled results over a heterogeneous surface with airborne observations. A further statistical analysis of the effects of land surface classification procedures over the study area and their influence on modelled results is performed. CLASS is tested over individual wetland types: bog, fen and marsh in a stand-alone (non-GCM coupled) mode. Atmospheric conditions are provided for the eight site locations from tower measured data, while each surface is parameterized within the model from site specific measurements. Resulting model turbulent and radiative flux output is then statistically evaluated against observed tower data. Findings show that while CLASS models vascular dominated wetland areas (fen and marsh) quite well, non-vascular wetlands (bogs) are poorly represented, even with improved soil descriptions. At times when the water table is close to the surface, evaporation is greatly overestimated, whereas lowered water tables generate a vastly underestimated latent heat flux. Because CLASS does not include a moisture transfer scheme applicable for non-vascular vegetation, the description of this vegetation type as either a vascular plant or bare soil appears inappropriate.CLASS was then tuned for a specific bog location found in the Hudson Bay Lowland (HBL) during the Northern Wetlands Study (NOWES). With bog surfaces better described within the model, testing of CLASS over a highly heterogeneous 169 km2 HBL region is then undertaken. The model is first modified for lake and pond surfaces and then separate runs for bog, fen, lake and tree/shrub categories is undertaken. Using a GIS, the test region under which airborne flux measurements are available is divided into 104 grid cells and proportions of each surface type are calculated within each cell. Findings indicate that although the modelled grid average radiation and flux values are reasonably well reproduced (4% error for net radiation, 10% for latent heat flux and 30% for sensible heat flux), spatial agreement between modelled and observed grid cells is disappointing.

Le fait dorsétien reste à ce jour, en préhistoire de l’Arctique, sujet à de nombreux débats quant à sa définition exacte, les modalités entourant son implantation, son expansion et sa disparition de la portion Est de l’Arctique canadien, ainsi que l’organisation socioéconomique qui le caractérise. La compréhension des chaînes opératoires reliées à la production de la culture matérielle constitue un moyen privilégié d’accéder à l’univers des choix techniques et socioéconomiques. Suivant la documentation ethnographique, nous considérons que l’analyse de la séquence de traitement des peaux, dans le but de produire les vêtements et l’équipement nécessaires à la survie en milieu arctique, peut donner accès aux modes de gestions des différentes phases de cette activité technique dans le temps et dans l’espace, ainsi qu’à la nature de la contribution féminine au cours du cycle saisonnier d’exploitation des ressources. Cette étude démontre que, suivant les similarités et les contrastes extraits d’une confrontation entre les modes de gestion des chaînes opératoires de traitement des peaux Inuit et Dorsétien, il est possible de proposer un modèle révélant le mode d’organisation socioéconomique de ces derniers, ainsi que d’aborder la nature des relations sociales (relations de genre) sous-jacentes. Étant soumis à un cycle saisonnier de disponibilité et d’accessibilité aux ressources, ainsi qu’à des besoins matériels équivalent à celui ceux des Inuits, les peuples dorsétiens ont pu élaborer un mode de gestion de leurs activités techniques et de leurs relations sociales particulier, en accord avec une réalité culturelle et sociale qui se distingue de celle de leurs successeurs. La combinaison des analyses tracéologiques (identification de la fonction de l’outillage en chert et en quartz) et spatiales, complétée par une analyse des relations de genre, permet de générer les données nécessaire à ce type d’étude. Les trois sites archéologiques sélectionnés sont situés le long du littoral sud du détroit d’Hudson au Nunavik. La période culturelle couverte par ces derniers comprend la phase de transition du paléoesquimau ancien au paléoesquimau récent (Pita KcFr-5 / 2800-2600 AA), ainsi que la phase dite Dorsétienne (Tivi KcFr-8A / 2600-1000 AA et Tayara KbFk-7 / 2125 – 1186 AA).

An understanding of the chaînes opératoires related to their material culture represents a privileged path to access a universe of technical and socioeconomic choices. By following the ethnographical documentation, we consider that the analysis of the skins working process, for the purpose of producing the garments and equipment necessary to survive in an Arctic environment, could provide access to methods to manage the different phases of this technical activity in time and space, in addition to showing the nature of female contributions throughout seasonal cycles of resources availability. This study demonstrates that, by looking at the différences and similarities gathered through a comparison between the management methods of production processes to treat animal skins used by the Inuit and Dorset cultures, it is possible to suggest a relevant model of the socioeconomic organization of the latter, as well as to approach the nature of their underlying social and gender relations. Being subject to a seansonal cyle of availability and access to resources, while experiencing material needs équivalent to those of the Inuit, the Dorset peoples were able to create a particular method for managing their technical activities and their social relationships, consistent with a cultural and social reality that differs from the one experienced by their successors. A combination of use-wear analyses (identification of the use of tools in chert and quartz) and spatial analyses, completed by an analysis of gender relationships, allows the data necessary in this type of study to be generated. The three archaeological sites chosen are located along the southern coastline of the Hudson Strait in Nunavik. The cultural period covered by these sites covers the transitional phase from ancient to récent Paleo-Eskimo (Pita KcFr-5/2800-2600 B.P.), as well as the one knows as the Dorset phase (Tivi KcFr-8A/2600-1000 B.P. and Tayara KbFk-7/2125-1186 B.P.). Keywords: Paleo-Eskimo, Dorset, skin process chaîne opératoire, lithic analysis, use-wear analysis, archaeological experiments, ethno-archaeology, gender analysis, household analysis, seasonal cycle, tools function, microblades.

Full textAbstract:
The overall objective of this research is to determine whether the position of
black women in traditional communities in small-scale agriculture in South
Africa has improved since 1993. The community of Mantsie in Lehurutshe is
used as a case study. To achieve this objective the study was divided into a
theoretical literature study and an empirical study.
The theoretical literature study was also divided into two parts. Chapter 2 looks
at the traditional customs of the Tswana culture and the role of women therein.
Chapter 3 investigates the various theoretical changes (if any) that has
occurred in the position of black women in traditional communities' dependant
for their livelihoods on small-scale agriculture. Chapter 4 contains the results of
the empirical study, which consists of a structured questionnaire and semi
structured interviews, which were conducted with the women of the Mantsie
community.
It has become very clear during the study that women are very important role
players in the food security of their rural communities. Although women have
been singled out in policy and legislation, it is very clear that they still
experience practical problems and obstacles in their agricultural activities.
Nevertheless, the women of Mantsie feel that their position has improved and
that it will improve further. In light of the research results a few
recommendations have been made at the end of the dissertation for the
empowerment of the women of Mantsie.Thesis (M. Development and Management)--North-West University, Potchefstroom Campus, 2004.
