description: E-relevant web text sites (EWT sites) are a relatively new phenomenon featuring banal yet remarkable user-generated texts on dedicated websites. This thesis analyses the sociosemiotic dimension of EWT sites in enabling neo-phatic communication: communication based on the relatable nature of EWT content and user-friendly medium, affording communicative acts without the requirement for in-depth discussion. Rather than fostering serious exchange, neo-phatic communication aims to establish a form of contact less brief than a greeting but akin to its purport, developing from banal but shared experiences. Analysis of the signification process involved in EWT sites, through a sociosemiotic framework based on Peirce’s second trichotomy of signs (icon, index, symbol) and the frame analysis of Goffman, shows that the sites’ semiotic structure belongs to a neo-phatic kind of communication unique to computer-mediated communication. This study illustrates how content with minimal substance might be under-valued as a means of understanding modern communication behaviour.

description: The provisions to determine the deflection of gypsum wallboard (GWB) sheathed shearwalls available in the Canadian and American standards are limited to nailed shearwalls and are rudimentary compared to the wood based sheathing equations. There is currently no fastener slip model for the GWB sheathed shearwalls that are fastened with GWB screws. A main goal of this study is to improve the existing equations for nailed GWB sheathed shearwalls and develop a suitable analytical expression that can be used for GWB fastened with screws. In total, 270 GWB sheathed joints were subjected to reversed cyclic loading with variations including GWB type, thickness, fastener type, fastener size and manufacturers. The power model type is used to develop the fastener slip equations for nails and screws, which have GWB density and fastener diameter as equation inputs. The accuracy of the developed model is then validated by comparing the tested full-scale GWB sheathed shearwall deflection to the deflection calculated using the newly proposed fastener slip models. The proposed equation is a significant improvement to the existing code provisions. Component testing was performed on the fasteners (center point bending test) and the GWB (dowel bearing test). The results of these tests were used to determine the joint capacity based on the European Yield Model. It was also found that the shearwall capacity could be predicted by considering the joint level capacity while accounting for the number of joints at a panel edge. The joint level and full-scale experimental results are also validated with the use of an analysis program (SAPWood) to model the joint level hysteresis as a hysteretic spring with 10 model fitting parameters. The developed joint level hysteretic model was then used to represent the fasteners connecting the sheathing panels to the lumber framing in the construction of the full-scale shearwall model.

description: The growing use of agent systems and the widespread penetration of the Internet has opened up new possibilities for scientific collaboration. We have been investigating the role for agent systems to aid with collaboration among Experimental High-Energy Physics (EHEP) physicists. A necessary component is an agreed ontology, which must include complex mathematical relations involving such quantities as the energy and momentum of elementary physics particles. We claim that the current web-ontology specification languages are not sufficiently expressive to be useful for explicit representation of mathematical expressions. We adapt some previous work on representing mathematical expressions to produce a set of mathematical representational primitives and supporting definitions that will allow knowledge sharing in agent systems. The paper sketches out a scheme for dealing with mathematical relations in scientific domain web-ontologies, illustrated with examples arising from our interactions with the EHEP physicists.

description: Depuis 2006, les artistes de indie rock sont les vedettes de « sessions audiovisuelles » diffusées sur le web, dans lesquelles les musiciens font des prestations dans des lieux inusités. Les artistes et publics revendiquant l’authenticité ont rapidement adhéré à cette vague de productions qui se manifestent surtout sur des sites musicaux et médiatiques (La Blogothèque, Black Cab Sessions, BRBR, La Fabrique culturelle, Bande à part, etc.), des sites commandités (Burberry Sessions, Scion Sessions, Nokia Lumia Live Sessions, etc.) et à la télévision (Mange ta ville, Voir, Formule Diaz, Fabriqué au Québec, etc.). Dans le cadre de cette recherche, nous avons voulu explorer la quête d’authenticité dans les médiations de la musique pour déterminer comment les intermédiaires culturels arrivent à respecter la nécessité perçue de favoriser une communication directe entre créateurs et publics. L’approche des production studies nous a permis de bien évaluer le rôle et le discours des artisans de la télévision culturelle, en particulier leurs visions artistiques et créatives dans le travail de médiation. Nous avons utilisé une méthode qualitative pour étudier le travail des intermédiaires culturels, soit l’étude de cas mobilisant des principes ethnographiques. Les conclusions font ressortir le double rôle de producteurs/consommateurs des artisans à l’étude comme moyen d’assurer l’authenticité des productions, le brouillage des frontières dans le travail des intermédiaires culturels (entre activités professionnelles et personnelles, entre jugement professionnel et goûts personnels, entre rôles d’administrateurs, artistes et publics, etc.) et la perception des publics de ces productions.

description: The purpose of this work is to center dance at the heart of Métis identity expressions, where reconnecting with who we are through dance is intimately grounded within an Indigenous understanding of restoring wellbeing. Exploring the experiences of four prominent Métis women allowed a space to celebrate the voice of dancers as they make sense of what it means to practice Métis dance within their lives. This research further focuses on the experiences of Métis dance as an understanding of Indigenous wellbeing. The lived experiences were collected and reviewed within an Indigenous research framework grounded in the Cree and Métis values of Mino-pimatisiwin (good life) and Wahkotowin (kinship) (Hart, 1999; Kelsey, 2008). Both concepts deeply inform the processes related to our reciprocal relationship to all things, living and non-living and further place emphasis on our shared responsibility to honour, respect and acknowledge Indigenous knowledge and its value to our communities. There were three findings that emerged from this study: Understanding Métis dance (1) as a restorative and relational praxis of self-knowing; 2) as intergenerational knowledge transfer; 3) as a site for growing cultural awareness and self esteem. The voices of the women celebrate Métis peoplehood through the restorative practice of dance and in doing so allow us to un-settle and re-center the notion of Métis identity and dispel the question of “authenticity” (Lawrence, 2003). These are our own personal stories to tell, and only we can rewrite them in a way that is beneficial and meaningful to us.
Significance and Distribution of Apatite in the Triassic Doig Phosphate Zone, Western Canada Sedimentary Basin

description: The Doig Phosphate Zone (DPZ) is a phosphate-bearing marine unit located at the base of the Doig Formation, in the Triassic section of the Western Canada Sedimentary Basin. The DPZ has a maximum thickness of 90 m and extends across northeastern British Columbia and west-central Alberta. In this study, we characterize the significance and interpret the origin of apatite in the DPZ through mineralogical and geochemical analyses, thin section study, and field emission scanning electron microscopy. The occurrence of apatite in the DPZ is not evenly distributed but restricted to discrete 10 to 20 cm thick beds, located near the base of the DPZ. Phosphorites are of two types: grainstones composed primarily of unconformity-bounded coated grains, and intraclastic phosphorites composed of detrital silt-sized grains and apatite coated grains in a cryptocrystalline phosphatic matrix. The phosphorite beds are records of stratigraphic condensation due to low detrital input during transgression. The erosionally truncated phosphatic coated grains and intraclasts are interpreted to be a result of various phases of phosphatization, exhumation, erosion, reworking, winnowing, and redeposition in alternating quiescence and storms or bottom currents. The abundance of pyrite and chalcophile trace elements, as well as the low concentration of proxy elements for organic matter productivity and preservation, are further evidence of stratigraphic condensation, with sulfidic pore water development and extensive organic recycling promoted by biological activity during the long exposure times. The phosphorites were formed under oxygenated water conditions, as suggested by the depletion in Ce and the presence of a diverse benthic fauna.

description: Embryonic stem cells (ESCs) possess hypo-immunogenic properties and have the capacity to modulate allogeneic immune response. ESCs have been shown to reduce immune activation in response to third party antigen presenting cells (APCs) in vitro and have the capacity to promote allograft survival in vivo. Clinical use of live ESCs to treat immunological disorders, however, risks teratoma or ectopic tissue formation. Accordingly, the way lab is studying the immune modulatory potentials of ESC-derived factors and recently, found that dendritic cells (DCs) treated with human ESC extracts are poor stimulators of purified allogeneic T cells compared to those DCs treated with vehicle or fibroblast extracts. In the present study, I found that ESC-derived extracts directly inhibit T cell proliferation and suppress their activation without inducing cell death. Furthermore, ESC extracts are able to suppress Th1 polarization while increasing the numbers of Foxp3+ CD4+ CD25+ regulatory T cells. Moreover, I found that a protein called Milk fat globule-EGF factor 8 (MFG-E8) appears to be highly expressed in ESCs. Importantly, neutralizing MFG-E8 substantially abrogated the immune suppressive effects of ESC extracts on T cell activation. These findings lead to future studies to further define specific immunomodulatory factors derived from ESCs for potential applications.

description: The inadvertent ingestion of contaminated soil is the dominant exposure route of non-volatile and semi-volatile contaminants such as polycyclic aromatic hydrocarbons (PAHs). Quantitative mass balance soil ingestion studies have been used to determine soil ingestion rates for use in human health risk assessments (HHRA) that can be used to predict the likelihood of adverse effects in individuals exposed to hazardous contaminants such as PAHs in contaminated soil. The Cold Lake region of Alberta is one of the three major oil sands regions of Alberta, and PAH concentrations in this oil sand region may be elevated in the atmosphere and the soil, resulting in increased exposures to PAHs. The area is home to Cold Lake First Nation who practice traditional activities and lifestyles that may put them in greater contact with soil than previous soil ingestion studies suggest. The primary objective of this research was to assess the soil ingestion rate in a group of First Nations subjects inhabiting the Cold lake region, and assess the carcinogenic risk posed by exposures to PAHs in air and soil. The study employed a quantitative mass balance tracer approach to estimate soil ingestion rates, and followed 9 subjects over a 13 day period. Soil and air samples were simultaneously collected to assess PAH contamination. The mean soil ingestion rate using Al and Si elemental tracers was 52 mg d-1, with a 90th percentile of 220 mg d-1, and a median soil ingestion rate of 37 mg d-1. These values are greater than the soil ingestion rates for HHRA recommended by Health Canada. The mean increase in excess lifetime cancer risk posed by inadvertent ingestion of soil to a First Nations’ individuals following traditional activities was 0.02 cases per 100,000 people with a 95% risk level of 0.067 cases per 100,000 people. Exposure to PAHs through inhalation posed a maximum lifetime cancer risk below 0.1 cases per 100,000, people. Thus, this study found no appreciable increase in excess lifetime associated with PAH exposure of First Nations’ people in the Cold Lake region.
Weaknesses and Vulnerabilities in Modern AI: Integrity

description: In the development of AI systems for mission applications, it is essential to recognize the kinds of weaknesses and vulnerabilities unique to modern AI models. This is important for design, implementation, and test and evaluation (T&E) for AI models and AI-based systems. The October 2023 Executive Order on AI highlights the importance of red teams, and we can expect that these weaknesses and vulnerabilities will be a focus of attention for any T&E activity. This blog post examines a number of specific weaknesses and vulnerabilities associated with modern artificial intelligence (AI) models that are based on neural networks. These neural models include machine learning (ML) and generative AI, particularly large language models (LLMs). We focus on three aspects:

 Triggers, including both attack vectors for deliberate adversarial action (exploiting vulnerabilities) and intrinsic limitiations due to the statistical nature of the models (manifestations from weaknesses)
 The nature of operational consequences, including the kinds of potential failures or harms in operations
 Methods to mitigate them, including both engineering and operational actions

This is the second installment in a four-part series of blog posts focused on AI for critical systems where trustworthiness - based on checkable evidence - is essential for operational acceptance. The four parts are relatively independent of each other and address this challenge in stages.
Revisiting associations between student performance outcomes and formative assessment opportunities: is there any impact on student learning?

description: This project developed as a result of some inconclusive data from an investigation of whether a relationship existed between the use of formative assessment opportunities and performance, as measured by final grade. We were expecting to show our colleagues and students that use of formative assessment resources had the potential to improve performance. This first study, done in semester 1 2002, indicated that there was no apparent relationship even though the students reported how useful they found the resources. This led us to ask if there was a transition effect such that students were not yet working in an independent way and making full use of the resources, and/or whether in order to see an effect we needed to persuade non-users of the resources to become users before investigating if use can be correlated with improvement in performance. With the 2002-3 NextEd ASCILITE Research Grant we set out to repeat our project and to look at use and usefulness of resources in both first and second semester, to encourage non-users to become users and to investigate use with performance. Now our story has a different ending.
Voguing the Veil: Exploring an Emerging Youth Subculture of Muslim Women Fashioning a New Canadian Identity

description: The population of 2nd generation Canadian-Muslim women who choose to veil, or wear the hijab, is steadily increasing. Rather than inquire why these women choose to do so, this study explores how Muslim youth use the veil as a fashion accessory. Guided by research questions that focus on the representation of the veil in popular culture, this study explores the veil as a sign as the women negotiate ‘being Muslim’ and ‘being Canadian’. Informed by a cultural studies conceptual framework, veiling in fashionable ways, or, ‘voguing the veil’, is explored as a form of ‘public pedagogy’ (Giroux, 2004). Using an Advocacy and Participatory methodology, the four women and myself engage in a collaborative inquiry examining meanings behind how we vogue the veil. Through a series of interviews, focus groups and journal entries accompanied by personal photographs (photovoice), the women and I co-construct narratives around their identity as women who veil in ways that contest dominant discourse. Together we explore the impact of constructs such as beauty, femininity and sexuality on our identities as Muslim women who veil in Canada. Co-constructing participant case studies permits readers “access to the world from the view-point of individuals who have not traditionally held control over the means of imaging the world” (Berg, 2007, p. 233), at many times surprising and contradicting what is ‘known’ about the veiled Muslim woman. The findings reveal themes that deeply impact how the women choose to veil. These themes include the strategies the women use to employ their veils as a means of agency and how, within and through different pedagogical spaces, the women’s performances and performativity of the veil shifts. The women in the study demonstrate that by ‘voguing the veil’, they are in fact attempting to transform the meaning of the veil as a marker of Canadian Identity. Using the voices, photos and narratives of the four women I argue that through ‘voguing the veil’ these young Muslim women are actively entering into and creating spaces so to be seen as an integral part of Canadian society and as such can be recognized as an emerging subculture.

description: The English-language translations of Jorge Luis Borges’s Spanish-language works undertaken by the author and Norman Di Giovanni went above and beyond what is generally perceived as acceptable in traditional Western practices. Their work, together with Borges’s thoughts on translation itself, garnered criticism from within Western Translation Studies for its rejection of the status of the original text and the blurring of the distinction between author and translator. Yet the pair’s actions and Borges’s views on translation cease to appear scandalous under the light of Buddhist philosophy, particularly through the use of the Buddhist principles that all phenomena are impermanent and interdependent. This thesis will seek to use these ideas to legitimize the actions of Borges and Di Giovanni. To do so, it will trace the history of opposing and convergent theories from Western philosophy and describe our Buddhist concepts in detail. In order to better understand Borges, it will examine the array of philosophies that influenced the writer and how they both align themselves and differ from Buddhist ideas. This thesis will end by directly applying impermanence and interdependence to the translation practices of Borges and Di Giovanni and considering what potential effect legitimacy for such practices would have on translation overall.

description: In decentralized optimization over networks, synchronizing the updates of all nodes incurs significant communication overhead. For this reason, much of the recent literature has focused on the analysis and design of asynchronous optimization algorithms where nodes can activate anytime and contact a single neighbor to complete an iteration together. However, most works assume that the neighbor selection is done at random based on a fixed probability distribution (e.g., uniform), a choice that ignores the optimization landscape at the moment of activation. Instead, in this work we introduce an optimization-aware selection rule that chooses the neighbor providing the highest dual cost improvement (a quantity related to a dualization of the problem based on consensus). This scheme is related to the coordinate descent (CD) method with the Gauss-Southwell (GS) rule for coordinate updates; in our setting however, only a subset of coordinates is accessible at each iteration (because each node can communicate only with its neighbors), so the existing literature on GS methods does not apply. To overcome this difficulty, we develop a new analytical framework for smooth and strongly convex functions that covers our new class of setwise CD algorithms -- a class that applies to both decentralized and parallel distributed computing scenarios -- and we show that the proposed setwise GS rule can speed up the convergence in terms of iterations by a factor equal to the size of the largest coordinate set. We analyze extensions of these algorithms that exploit the knowledge of the smoothness constants when available and otherwise propose an algorithm to estimate these constants. Finally, we validate our theoretical results through extensive simulations.

Effects of Habitat Change on Bird Species Richness in Ontario, Canada

description: It is generally assumed that when natural habitat is converted to human-dominated cover such area is “lost” to its native species. Extinctions will ensue. The literature generally assumes that species are extirpated as natural area is reduced, following the well-known species-area relationship (SAR). However, SARs have consistently over-estimated species losses resulting from conversion of natural habitat to human-dominated land covers. We hypothesize that the overestimation occurs because these area-based models assume that converted habitat is “lost”, eliminating all species. However, in the real world, conversion of natural land cover to human-dominated cover frequently produces new land covers, different from the original habitat, but not necessarily completely inhospitable to biodiversity. We evaluated the responses of total avian richness, forest bird richness and open habitat bird richness to remaining natural area within 991 quadrats, each 100 km2, across southern Ontario. Total bird species richness does not follow SAR predictions; rather, the number of bird species peaks at roughly 50% natural land cover. The richness of forest birds does follow the usual SAR power-law as a function of forested area. In contrast, richness of birds that prefer open-habitat does not increase monotonically with either natural- or human-dominated land cover. However, we can partition human-dominated land cover into an “available human-dominated” component and “lost” habitat. Richness of open-habitat species relates to the amount of available human-dominated cover. Distinguishing three habitat types (natural, available human-dominated, and lost) permits accurate predictions of species losses in response to natural habitat conversion.

La thèse porte sur la mobilisation du groupe Égalité santé en français et sa contestation de la réforme du système de santé néo-brunswickois en 2008. Elle utilise la notion de cadrage pour mieux comprendre les discours véhiculés dans les médias de la province sur le sujet de la réforme. La thèse étudie, en particulier, le discours d’Égalité santé en français afin de mieux comprendre les raisons qui ont poussé le groupe à privilégier la voie juridique pour mener sa contestation de la réforme du système de santé. Au plan méthodologique, la thèse procède à une analyse de discours à partir d’une revue de presse tirée des principaux journaux néo-brunswickois. Abstract This thesis studies the legalization of Acadian claims in healthcare. It presents a case study of the mobilisation of Égalité santé en français and its legal battle against the New Brunswick health reform of 2008. The research will exploit framing theories to better understand the various discourses that were reflected in the province’s media. It will also study the reasons that pushed Égalité santé en français to favour a legal strategy. This will be achieved thru discourse analysis that will be applied to a press review of articles published in New Brunswick’s main newspapers.

description: In ad-hoc networks, the optimal hop size is a trade-off between the transmission errors and the number of hops required. This paper investigates the optimal hop size and transmission strategy in networks with overlaid base stations. The objective is to maximize the minimum throughput any user achieves, excluding traffic that it relays. The optimum depends on the routing algorithm used, and a specific receiver-based algorithm is proposed. Optimal parameters are derived using a simplified model, and are shown by simulation to out-perform systems with the optimal position-invariant hop size. For this choice of objective, improvement is obtained by using one hop size for the base station and another for relays.

description: Aims: To evaluate pediatric type 1 diabetes telehealth visits during the COVID-19 pandemic, with a focus on assessing the usability of these visits and gathering patient perspectives. Methods: An online survey, which included a validated telehealth usability questionnaire, was offered via email to families with a telephone or virtual visit since the COVID-19-related cancellation of routine in-person care. Survey data was linked with the British Columbia (BC) Clinical Diabetes Registry. Outcomes between groups were assessed using Welch’s t-test. Associations with type of visit as well as with desire to return to in-person care were assessed with logistic regression models. Results: The response rate was 47%. Of 141 survey respondents, 87 had clinical data available in the BC Clinical Diabetes Registry, and thus were included in our analysis. Overall, telephone and virtual visits were rated highly for usability. Telephone visits were easier to learn to use, and simpler to understand; however, telephone and virtual visits were similar across multiple areas. No factors associated with choosing one type of visit over the other, or with desire to return to in-person care, could be identified. 72% of participants want future telehealth care; however, some would like all future care to be in-person. Conclusions: Telephone and virtual visits had impressive usability. Many families want telehealth to play a significant part in their future care.

description: The objectives of this thesis were: (1) to quantify seasonal groundwater contribution to total stream discharge and (2) further our understanding of sub-arctic carbon sources and pathways within a sub-arctic discontinuous permafrost river catchment. Twenty-two samples were taken from the North Klondike River, 14 samples from 5 of its tributaries, and 46 rain and snowmelt samples from the Dawson City Airport, Yukon, Canada,. During the winter months, groundwater is responsible for greater than 95% of total river discharge. Spring freshet and summer flow bring snowmelt and precipitation, contributing anywhere from 30% to greater than 60% of total river discharge. Groundwater is characterised by high concentrations of geogenic solutes from weathering during recharge, dissolved inorganic carbon, and carbon-14 activities of 0.61 pMC. Tritium activities indicate a fast moving system, with groundwater ages measuring less than 10 years. The most significant discharge of organic carbon from the system is during spring freshet (434,192 kg carbon). Primary productivity within the system is estimated to be 10.2 grams of carbon per metre squared, with approximately 96% of carbon being sequestered or emitted as carbon dioxide.

description: The present dissertation is a comparative investigation between the Germanic-like structural phenomena found in the left periphery of Old French (OF) clauses and the syntactic phenomena found in the left periphery of Old High German (OHG). The goal of this thesis is to provide evidence that only a synchronic analysis can explain the presence of Germanic-like structures in OF syntax. The reason for this lies in the similarities between the V2 properties found in OF and OHG. The two languages show V2 properties such as V-to-C movement and XP fronting, but also properties which are not found in Modern V2 languages such as a frequent V1 and V3 word order. The corpus I use consists of four OF texts from the 12th and 13th century which correspond to the late OF period. They are composed in different OF dialects from the northern part of France. The poetic texts chosen for this study are Le voyage de Saint-Brandan and Gormont et Isembart. The prose texts are Le Roman de Tristan en prose and Les Miracles de Saint Louis. I coded these OF documents according to certain criteria: main clause type, embedded clause type, finite verb position, first element preceding the finite verb, etc. The results indicate that OF can be considered a true V2-language that shares a certain amount of properties with OHG, namely V-to-C movement, XP fronting, Stylistic Fronting as well as verb-initial clauses. This thesis illustrates that the OF dialects closer situated to the Germanic language border show a higher frequency in Germanic-like syntactic phenomena than the dialects situated further away. A difference between poems and prose texts concerning the presence and intensity of certain syntactic phenomena can also be observed.

The growth in sensor applications and smart mobile phones that come equipped with built-in sensors has led to the integration of sensors with social networks. These days, people are heavily dependent on online social networks (OSNs); they migrate their real-life activities online through various types of multimedia such as photos, videos, text, etc., which turns OSNs into a soft-sensory resource about users' events. The users use these forms of multimedia to tell their friends about their daily lives. This social network data can be crawled to build personal context-aware stories about individuals. However, the number of social users and the quantity of multimedia that is produced on social media are both growing exponentially, which leads to the challenge of information overload on OSNs. The information needed for stories, such as events and their locations, is not fully available on user's own profile. It is true that part of the information can be retrieved from the user's timeline, but a large number of events and related multimedia information is only available on friends' profiles. In this thesis, we focus on identifying a subset of close friends in order to enrich the content of the story. The amount of time people spend together has been proven to play a key role in determining close ties between people. We propose a DST (Days Spent Together) algorithm to find a user's closest friends based on the days they spent together interacting face-to-face. With the closest friends information, we are able to find additional information to complement what was found on the user's own profile, as well as to personalize the stories to ensure that they are only about the users and their closest friends. Due to the possibility of multimedia (photos in this thesis) overload for events, we propose to use the duration of events measured by DST, to determine the number of representative photos for each event. Our experiments show that the proposed approach could recognize the close friends of users and rank them from the strongest to the weakest. The results also show that with the proposed method we get days-spent-together values that are close to the corresponding true values provided by users.

description: Cyanobacterial blooms and their toxins are a major water quality and potential health risk around the world. This thesis developed an analytical method for microcystin congeners in sediments in order to examine their fate in lakes and establish the history of toxin-producing cyanobacteria in relation to environmental change using lake sediments. A novel method for both intra- and extracellular microcystins in lake sediments was developed, consisting of accelerated solvent extraction, hydrophilic-lipophilic balance solid phase extraction and multiple reaction monitoring-based HPLC-MS/MS quantitation. The method achieved comparable recoveries of intra- and extracellular cyanotoxins based on nine microcystins and nodularin (marine analogue). The analytical method was validated using surficial and deeper sediments from seven lakes of diverse geography and trophic state. To study the fate of microcystins, a multi-year, whole lake study of Microcystis blooms was conducted to obtain both in situ and in vitro half-life estimates of microcystin-LA (MC-LA), an understudied, but increasingly reported microcystin. MC-LA appeared to undergo slower rates of decomposition and persist longer than the more frequently studied MC-LR. Experimentally, high light intensity increased in vitro decomposition of dissolved MC-LA while high temperature enhanced decomposition in the particulate phase. Sediment deposition measurements and estimates of sediment-pore water distribution coefficients, sediment accumulation rates, and diffusive fluxes indicated that microcystin congeners differ in their fate. Notably, MC-LA preferentially distributed into pore water and remobilized (by diffusion) from sediments and into overlying water while MC-RR adsorbed more strongly to sediment particles. Finally, the sediment record of an eutrophic lake of major recreational importance was examined to identify possible drivers of toxigenic cyanobacteria and determine if the perceived increase in toxigenic cyanobacteria could be corroborated. Microcystins were detected to the bottom of the core (early 1800s), indicating that toxigenic cyanobacteria were present prior to the first permanent settlements. Microcystins were significantly correlated with changes in diatom-inferred nutrients (DI-TP and DI-TKN) within the sediment core as well as with specific algal pigments. Sediment microcystins in the upper layers also significantly correlated with a 20-year monitoring record for water column microcystins suggesting that sediment microcystins can be used as a proxy for past surface water conditions.

description: Notre recherche qualitative, selon une perspective constructiviste, porte sur le choix scolaire des parents immigrants du Lycée Claudel, une école française à Ottawa, et sur l’engagement au français de leurs enfants. Cette recherche est une étude de cas qui s’appuie sur un cadre théorique faisant appel à plusieurs concepts clés : le choix scolaire, le marché, le capital, la reproduction, l’habitus, la représentation, la distinction, l’engagement, le maintien des langues et l’identité. Elle a pour objectif de répondre à trois questions : 1) comprendre pourquoi et comment les parents font le choix scolaire, 2) comment leurs enfants le vivent et 3) comment ce choix a un impact sur l’identité de certains enfants. Bien que le français se trouve à Ottawa en contexte minoritaire, il est majoritaire au Lycée Claudel, qui se positionne ainsi comme un haut lieu de distinction. En effet, les parents choisissent ce lycée pour l’accent français de France qui y prédomine alors qu’il n’est pas majoritaire au Canada, mais aussi pour la particularité de son milieu. Quoique tous les parents fassent ce choix en fonction du capital linguistique que représente le français, qui se convertira plus tard, pensent-ils, en capital économique pour donner sur le marché du travail un avenir plus prometteur à leurs enfants, les parents français le font également pour reproduire leur propre scolarité. En choisissant le lycée, les parents qui ne détiennent pas le français affrontent de nombreux enjeux par rapport à l’emploi limité de leur langue maternelle, tels que sa transmission et son maintien au sein de la famille et l’impact des autres langues sur elle. Notre étude montre la reproduction des discours des parents chez tous les enfants par rapport au français distinct appris dans cet établissement scolaire. En outre, certains enfants, qui ont une autre langue maternelle, tiennent compte du mélange culturel et linguistique où ils vivent. Ils décrivent les défis auxquels ils sont confrontés pour maintenir cette autre langue, qui n’occupe pas la même place que le français dans leur vie. À noter que, dans cette école, l’anglais est présent, tout comme dans les écoles de langue française. Enfin, notre étude permet de cerner les traces linguistiques et culturelles qui marquent les identités des enfants qui n’ont pas d’héritage français. Nous constatons que la scolarité en français a des conséquences sur l’identité de ces jeunes : immédiates sur le plan linguistique et, pour certains d’entre eux, plus subtiles sur le plan culturel. Des identités multiples et en mutation en sont le résultat. En définitive, notre travail souligne l’importance du choix scolaire dans la vie des enfants quand celui-ci est fait dans un contexte minoritaire francophone alors que ce choix est différent de celui de la société majoritaire à laquelle plusieurs familles appartiennent.
Are they all the same? Benefit realisation from e-marketplaces

description: This paper addresses the issue of benefit realisation from e-marketplaces and examines whether there are significant differences in benefit recognition according to the type of e marketplace used. An empirical study of two marketplaces and one buying organisation is used to analyse how the realisation of benefits may vary according to different e marketplace models. A comparison is made between an intermediary and a consortium marketplace before the benefits achieved by the buying organisation are discussed. The study found that although there were distinct differences between the e-marketplaces, many benefits are achievable from both. Benefit realisation was influenced more by the buyer's procurement strategies than by the features offered.

description: Crack initiation and propagation in the bladed disks of aero-engines caused by high-cycle fatigue under cyclic loads could result in the breakdown of the engines if not detected at an early stage. Although a number of fault detection methods have been reported in the literature, it still remains very challenging to develop a reliable online technique to accurately diagnose defects in bladed disks. One of the main challenges is to characterize signals contaminated by noises. These noises caused by very dynamic engine operation environment. This work presents a new technique for engine bladed disk crack detection, which utilizes advanced analysis of clearance and time-of-arrival signals acquired from blade tip sensors. This technique involves two stages of signal processing: 1) signal pre-processing for noise elimination from predetermined causes; and 2) signal post-processing for characterizing crack initiation and location. Experimental results from the spin rig test were used to validate technique predictions.
