Ti-Jean au pays des Madelinots : où l’infiniment petit rejoint l’infini

Résumant les conclusions d’un mémoire de maîtrise intitulé « Aspects du merveilleux dans les contes des Îles de la Madeleine » (cf.Rabaska, vol. 4, 2006, p. 212-213), cet article, en plus de donner un bref aperçu de l’historique de l’archipel madelinot, dresse un portrait général du corpus des contes madelinots. Il présente également un résumé de la vie et de la démarche de celui qui en a été le principal collecteur : le père Anselme Chiasson. Quelques caractéristiques du corpus sont aussi abordées, que ce soit au niveau des particularités linguistiques, formelles ou thématiques qui lui sont spécifiques. Enfin, un tableau regroupant et catégorisant tous les contes recueillis par le père Chiasson selon la méthode préconisée par les folkloristes Aarne et Thompson complète le portrait de ce corpus.This article summarises the conclusions of this author’s master’s thesis entitled «Aspects du merveilleux dans les contes des Îles de la Madeleine» (cf. Rabaska, vol. 4, 2006, p. 212-213). In addition, a brief history of the occupa-tion of the Magdalen Islands provides a context for the folktales gathered on the archipelago. It also outlines the life and the methods of the investigator responsible for gathering the collection of folktales: father Anselme Chiasson. Some of the characteristic features of this collection are also discussed as they address regional linguistic particularities, whether formal or thematic. Finally, an analytical grid outlines the variety and categories of folktales in Father Chiasson’s collection, using the approach developed by the folklorists Aarne and Thompson

Trois mesures du vocabulaire chez des élèves d’écoles françaises du Nouveau-Brunswick

La mesure du vocabulaire des jeunes néo-brunswickois se heurte à la rareté des tests disposant de normes adaptées et de données psychométriques actuelles. Trois tests de vocabulaire se prêtant bien à une utilisation individuelle ou de groupe sont analysés dans la présente étude : le test de vocabulaire Binois-Pichot (1959), le sous-test vocabulaire du Test collectif d’intelligence générale (Lavoie et Laurendeau, 1960) et le test de vocabulaire Mill Hill (Deltour, 1993). Trois échantillons d’élèves de la quatrième à la huitième année d’écoles françaises du Nouveau-Brunswick ont été examinés à l’aide de l’un de ces trois tests de vocabulaire. Les qualités métrologiques ainsi que des données normatives préliminaires sont rapportées pour chacun des trois instruments.Vocabulary assessment of French-speaking school children and adolescents in New Brunswick is limited by the dearth of tests with known psychometric properties and norms for this population. In the present study, three tests of receptive vocabulary appropriate for individual and group administration (the Binois-Pichot vocabulary test, 1959; the vocabulary sub-test of the Lavoie-Laurendeau Group Test of General Intelligence, 1960; Deltour’s Mill Hill vocabulary test, 1993) were examined in three samples of children and adolescents from grades 4 through 11 attending French-speaking schools in New Brunswick. Statistical analyses, psychometric properties and preliminary normative data are presented for each of the three instruments

The Effect of Season on \u3ci\u3ein vitro\u3c/i\u3e and \u3ci\u3ein vivo\u3c/i\u3e Exsheathment Efficacy of Stored Infective \u3ci\u3eHaemonchus contortus\u3c/i\u3e Larvae

Small ruminant farmers have a constant battle with infections of gastrointestinal nematode (GIN) within their grazing sheep and goats. Haemonchus contortus, more commonly called the barber pole worm, is the most pathogenic parasite that feeds on blood, eventually causing anemia and weight loss, and even death. Ruminants have a four-chambered stomach consisting of the reticulum, rumen, omasum, and abomasum. The life cycle of H. contortus begins in the abomasum where the adult worms reside and reproduce, and the resulting eggs are shed out in the feces. The eggs hatch to yield larvae, which grow to the infective third stage (L3). The H. contortus L3 are consumed by grazing sheep and goats. The L3 have a protective sheath covering that must be shed within the rumen in order for the larva to continue development into adults within the abomasum. The shedding of the sheath is called ‘exsheathment’ and is a critical part in the life cycle of H. contortus. Haemonchus contortus have become increasingly resistant to the chemical dewormers (anthelmintics) commonly used to control infections. Increasing anthelmintic resistance in these GIN creates a need for alternative methods of GIN control. Plant secondary compounds have demonstrated anti-parasitic activity and are currently the focus of many studies. Stored larvae are commonly utilized in in vitro and in vivo assays of plant secondary compounds. Although researchers typically do not use L3 that have been stored longer than three months, the effect of season on the viability and exsheathment of stored L3 is unknown. The objective of this study is to determine the effect of season on in vitro and in vivo exsheathment efficacy of stored H. contortus L3. Four donor rams were infected with 10,000 H. contortus L3 on the autumn equinox (fall, n=2) and on the winter solstice (winter, n=2). After the infection reached maturity (~ 4 weeks), fecal matter was collected and cultured for 10 days and the resulting L3 were harvested and stored at 4°C until assay. Each month, the larvae were artificially exsheathed in vitro using CO2 exposure and naturally exsheathed in vivo by the direct placement of ensheathed L3 into rumen fistulated ewes. The average exsheathment over six months for the in vivo and in vitro monthly assays of fall infection was 70 ± 4 (mean ± SEM) and 60 ± 4 respectively. The average exsheathment over three months for the in vivo and in vitro monthly assays of the winter infection was 63 ± 4 and 43 ± 4 respectively. Statistical analysis of the data is pending

Sonata V of Jan Dismas Zelenka : a study in style and genre

textThe music of the late baroque composer Jan Dismas Zelenka (1679- 1745) was not widely circulated during his lifetime. In the late twentieth century, Zelenka's music experienced a revival due to the rediscovery of his sonatas for double reed ensemble. The thesis examines the stylistic, generic, and historical context for Zelenka's Sonata V (ZWV 181, no. 5), tracing the development of the ensemble sonata for double reeds at the Augustan court. Chapter One focuses on Zelenka's life, as well as the purpose and dating of the six ensemble sonatas for obbligato double reeds (ZWV 181). The subsequent chapter surveys the national styles that were assimilated into the compositional traditions of the Dresden hofkapelle in the early 18th century. The role of the oboist within the court musical establishment and the social status of the hofmusicus are discussed. Chapter Three considers the precedents for and influences on Zelenka's Sonata V, particularly with respect to its inclusion in the little known genre of the sonata auf concertenart. These sonatas in the manner of a concerto adopt the formal outlines of Vivaldi's concertos and concerted sonatas while obscuring the distinctions of genre between the sonata and concerto through the treatment of scoring and texture. Zelenka's Sonata V follows the style of an early sonate auf concertenart of Vivaldi. Zelenka's concerted sonata departs from its model by confounding the identity of the initially distinct ritornello and solo material. The specific use of the oboe in Zelenka's sonatas, including playing techniques, and the degree of specialization are discussed. The conclusion speculates as to why Zelenka's music quickly fell out of favor and why even the composer himself was treated in a critical manner only a few generations after his time at Dresden. An understanding of the Dresden court not only provides a window on Zelenka's music, but also explains its almost immediate eclipse following his death.Musi

Intermodal Transit Terminal: Integrating the Future of Transit into the Urban Fabric

The very foundation of transportation relies on its ability to efficiently move people and goods through a transitional space. Transportation hubs are key to achieving this goal. However, many transit terminals are outdated or poorly designed to fit the needs of the modern world. At the core of this thesis are two overarching questions. First, how do we design intermodal transit terminals so that they successfully integrate into an existing urban fabric? Second, how do we design for innovative modes of transportation, such as hyperloop technology? This thesis explores how architectural design can recover existing transit connections within an urban context and provide new modes of transportation for a faster and more efficient user experience. Exploring the current issues within the transit sector today was a major focus of this research as well as selecting a site within an active city center. Furthermore, research into the emergence of new modes of transportation, like hyperloop technology and autonomous vehicles helped to identify potential transit solutions. Much of this research investigated the history of transit centers in addition to studying several important case studies that facilitated a solution to improving transit connections. Several design options were explored through this research and a selected design was integrated into a final design solution to help lay the path for a more efficient future in transit architecture

Clustering of variables for enhanced interpretability of predictive models

A new strategy is proposed for building easy to interpret predictive models in the context of a high-dimensional dataset, with a large number of highly correlated explanatory variables. The strategy is based on a first step of variables clustering using the CLustering of Variables around Latent Variables (CLV) method. The exploration of the hierarchical clustering dendrogram is undertaken in order to sequentially select the explanatory variables in a group-wise fashion. For model setting implementation, the dendrogram is used as the base-learner in an L2-boosting procedure. The proposed approach, named lmCLV, is illustrated on the basis of a toy-simulated example when the clusters and predictive equation are already known, and on a real case study dealing with the authentication of orange juices based on 1H-NMR spectroscopic analysis. In both illustrative examples, this procedure was shown to have similar predictive efficiency to other methods, with additional interpretability capacity. It is available in the R package ClustVarLV.Comment: 24 pages, 7 figure

Dimensionality reduction by clustering of variables while setting aside atypical variables

Clustering of variables is one possible approach for reducing the dimensionality of a dataset. However, all the variables are usually assigned to one of the clusters, even the scattered variables associated with atypical or noise information. The presence of this type of information could obscure the interpretation of the latent variables associated with the clusters, or even give rise to artificial clusters. We propose two strategies to address this problem. The first is a "K +1" strategy, which consists of introducing an additional group of variables,  called the "noise cluster" for simplicity. The second is based on the definition of sparse latent variables. Both strategies result in refined clusters for the identification of more relevant latent variables

Ballistic one-dimensional holes with strong g-factor anisotropy in germanium

We report experimental evidence of ballistic hole transport in one-dimensional quantum wires gate-defined in a strained SiGe/Ge/SiGe quantum well. At zero magnetic field, we observe conductance plateaus at integer multiples of 2e2/h. At finite magnetic field, the splitting of these plateaus by Zeeman effect reveals largely anisotropic g-factors with absolute values below 1 in the quantum-well plane, and exceeding 10 out-of-plane. This g-factor anisotropy is consistent with a heavy-hole character of the propagating valence-band states, which is in line with a predominant confinement in the growth direction. Remarkably, we observe quantized ballistic conductance in device channels up to 600 nm long. These findings mark an important step toward the realization of novel devices for applications in quantum spintronics

Spatial Distribution Modelling of Prothonotary Warbler (Protonotaria citrea) on Breeding Grounds

Ecological niche modeling is used to predict a species’ distribution in a geographic area based on abiotic and biotic variables. Understanding a species’ range is important for conservation and restoration efforts. As anthropogenic forces may alter or deplete habitat, it is important to know the ecological requirements of a species to understand how and what habitat to protect. With the increasing threat of climate change and rising temperature and precipitation, the suitable habitat and the distribution for many species is expected to shift. Migratory species are particularly at risk of these changes as they require suitable habitat not only on their wintering and stopover grounds, but on their breeding grounds. Without suitable breeding grounds, reproductive success is guaranteed to decline for a species. Understanding how these changes affect the range and distribution of a species allows researchers and conservationist to better formulate effective species management plan

GPS Multipath Detection in the Frequency Domain

Multipath is among the major sources of errors in precise positioning using GPS and continues to be extensively studied. Two Fast Fourier Transform (FFT)-based detectors are presented in this paper as GPS multipath detection techniques. The detectors are formulated as binary hypothesis tests under the assumption that the multipath exists for a sufficient time frame that allows its detection based on the quadrature arm of the coherent Early-minus-Late discriminator (Q EmL) for a scalar tracking loop (STL) or on the quadrature (Q EmL) and/or in-phase arm (I EmL) for a vector tracking loop (VTL), using an observation window of N samples. Performance analysis of the suggested detectors is done on multipath signal data acquired from the multipath environment simulator developed by the German Aerospace Centre (DLR) as well as on multipath data from real GPS signals. Application of the detection tests to correlator outputs of scalar and vector tracking loops shows that they may be used to exclude multipath contaminated satellites from the navigation solution. These detection techniques can be extended to other Global Navigation Satellite Systems (GNSS) such as GLONASS, Galileo and Beidou.Comment: 2016 European Navigation Conference (ENC 2016), May 2016, Helsinki, Finland.
