description: The study entitled 'Priorities in the Recruitment of French Immersion Teachers in British Columbia' compared the priorities of French immersion parents and school district Directors of Human Resources on issues surrounding French immersion teacher recruitment. A survey was sent to 44 Directors of Human Resources, representing all school districts with French immersion programs in the province, with a response rate of 64 percent. One hundred surveys were sent to French immersion parents in the province with a response rate of 48 percent. Seven follow-up interviews were conducted. The results of the survey revealed a consensus amongst parents, Directors of Human Resources and university French immersion pre-service teacher education programs in British Columbia on the minimum expected level of French proficiency for a French immersion teacher. Parents and Directors of Human Resources rated language skills as a top priority followed by teaching skills, personal qualities and knowledge of French culture. Nonetheless, respondents from both groups qualified their rankings by saying that it would be undesirable to possess one set of characteristics at the expense of another. Parents expressed a preference for francophone French immersion teachers, particularly from Quebec, and may therefore be surprised by the high number of anglophones teaching in the program. Directors of Human Resources expressed a preference for hiring graduates from the French immersion stream df pre-service teacher education programs followed by bilingual anglophones. They suggested that anglophones tended to be local teachers who, due to their familiarity with school culture, would be easier to retain than teachers from elsewhere. Using a teacher shortage spectrum formulated for this study, Directors of Human Resources provided the average number of job applicants for a typical job opening in the French immersion and English streams in the 2001 - 2002 school-year in their school district. A shortage of French immersion teachers was found to exist in British Columbia. The shortage is worse in rural school districts than in urban school districts. No shortage of teachers was reported in the English stream. Encouragingly, all school districts reported that they verify the level of French proficiency of French immersion teacher candidates although the tools used to do s o vary significantly from district to district, from checking course work credentials only to having prospective immersion teachers complete oral and written tests. Parents and Directors of Human Resources expressed opposition to lowering hiring standards in order to address and shortage of French immersion teachers.

description: Road extraction in remote sensing images is of great importance for a wide range of applications. Because of the complex background, and high density, most of the existing methods fail to accurately extract a road network that appears correct and complete. Moreover, they suffer from either insufficient training data or high costs of manual annotation. To address these problems, we introduce a new model to apply structured domain adaption for synthetic image generation and road segmentation. We incorporate a feature pyramid network into generative adversarial networks to minimize the difference between the source and target domains. A generator is learned to produce quality synthetic images, and the discriminator attempts to distinguish them. We also propose a feature pyramid network that improves the performance of the proposed model by extracting effective features from all the layers of the network for describing different scales objects. Indeed, a novel scale-wise architecture is introduced to learn from the multi-level feature maps and improve the semantics of the features. For optimization, the model is trained by a joint reconstruction loss function, which minimizes the difference between the fake images and the real ones. A wide range of experiments on three datasets prove the superior performance of the proposed approach in terms of accuracy and efficiency. In particular, our model achieves state-of-the-art 78.86 IOU on the Massachusetts dataset with 14.89M parameters and 86.78B FLOPs, with 4x fewer FLOPs but higher accuracy (+3.47% IOU) than the top performer among state-of-the-art approaches used in the evaluation.

description: The contribution of institutional credit to agricultural growth has been estimated in the state of Punjab. The demand-supply situation under different scenarios and change therein over a decade period have been examined. A simultaneous (four) equation model has been used to estimate the contribution of institutional credit towards use of production inputs, private investments and agricultural growth. The study has revealed that supply of production credit doubled and that of investment credit increased by about 80 per cent during the period 2001-02 to 2003-04. It took more than 15 years to double from 1984-85 to 2000-01. The relationship between use of variable inputs and production credit disbursement has been found highly significant. A similar relationship has prevailed between private capital formation and investment credit. The results have further exhibited significant and positive impact of capital investments on productivity with elasticity of 1.02. Higher use of inputs was ushered by favourable input-output pricing policy along with easy and cheap short-term credit availability in the state. Private capital formation has also helped in increasing the use of variable inputs in the crop sector. The contribution of institutional credit in promoting use of modern production inputs and private capital investments has been found to be significantly positive. The demand-supply situation in terms of short-term institutional credit has undergone a change over time, with the demand exceeding supply by 49 per cent in 1995-96, but later, the supply has been found exceeding demand by 122 per cent in the year 2005-06. It, therefore, becomes imperative that first the demand for agricultural credit in each state/region be assessed, depending on crop patterns and current inputs and capital requirements in relation to targeted output growth-rate and then, policy framework should be put in place to meet those requirements, instead of increasing the credit supply uniformly across the board in all the states/ regions of the country. Such a policy sometimes proves counterproductive and that appears to have happened in the Punjab agriculture.

description: Behavior of doped fermions in $Z_2$ gauge theories for the quantum dimer and eight-vertex models is studied. Fermions carry charge and spin degrees of freedom. In the confinement phase of the $Z_2$ gauge theories, these internal symmetries are spontaneously broken and a superconducting or Neél state appears. On the other hand in the deconfinement-topologically-ordered state, all symmetries are respected. From the view point of the quantum dimer and eight-vertex models, this result indicates interplay of the phase structure of the doped fermions and background configuration of the dimer or the eight-vertex groundstate. At the quantum phase transitions in these systems, structure of the doped-fermions groundstate and also that of the background dimer or eight-vertex groundstate both change. Translational symmetry breaking induces a superconducting or antiferromagnetic state of the doped fermions.

description: Randomized Greedy Algorithms (RGAs) are interesting approaches to solve problems whose structures are not well understood as well as problems in combinatorial optimization which incorporate the random processes and the greedy algorithms. This paper introduces a new algorithm that combines the major features of RGAs and Shortest Path Tree Algorithm (SPTA) to deal with the Clustered Shortest-Path Tree Problem (CluSPT). In our algorithm, SPTA is used to determine the shortest path tree in each cluster while the combination between characteristics of the RGAs and search strategy of SPTA is used to constructed the edges connecting clusters. To evaluate the performance of the proposed algorithm, Euclidean benchmarks are selected. The experimental investigations show the strengths of the proposed algorithm in comparison with some existing algorithms. We also analyze the influence of the parameters on the performance of the algorithm.

description: Dans cette réflexion sur le rapport entre langue et musique, nous montrerons que le qualificatif « langue musicale » utilisé dans le langage courant ne correspond pas à une réalité linguistique en sciences du langage. Les linguistes qui ont utilisé ce qualificatif l’ont fait de manière métaphorique pour discuter soit la perception d’une langue étrangère, qui ne signifie pas que la langue en soi est musicale, soit des faits rythmiques ou phonétiques–prosodiques en langue naturelle. Comme ces derniers sont une manifestation de l’expressivité dans le langage, nous avons comparé l’approche de C. Bally sur l’expressivité et celle de R. Jakobson sur la fonction poétique pour montrer leurs points communs et leur spécificité. Notre conclusion est que les fonctions expressive et poétique de R. Jakobson se retrouvent dans ce que C. Bally avait nommé expressivité et que l’approche fonctionnelle du premier n’est pas radicalement différente de l’approche linguistique, plus riche, du second.

description: In the context of the ongoing search for the QCD critical point at the Relativistic Heavy-Ion Collider, we study the equation of state near the critical point in the temperature and baryon chemical potential plane. We use the parametric representation introduced in earlier literature, which maps the universal 3D Ising equation of state onto the QCD phase diagram using several non-universal parameters. We focus on the quartic cumulant of the baryon number, or baryon number susceptibility~$χ_4^B$, which can be accessed experimentally via net-proton fluctuation kurtosis measurements. It was originally predicted, through universality arguments based on the {\em leading} singular contribution, that $χ_4^B$ and net-proton kurtosis should show a specific non-monotonic behavior due to the critical point. In particular, when following the freeze-out curve on the phase diagram by decreasing beam energy, the kurtosis is expected to dip, and then peak, when the beam energy scan passes close to the critical point. We study the effects of the non-universal and thus far unknown parameters of the Ising-to-QCD mapping on the behavior of~$χ_4^B$. We find that, while the peak remains a solid feature, the presence of the critical point does not necessarily cause a dip in $χ_4^B$ on the freezeout line {\em below} the transition temperature. The critical point contribution to the dip appears only for a narrow set of mapping parameters, when subleading singular terms are sufficiently suppressed.

description: Quantum phenomena such as entanglement can improve fundamental limits on the sensitivity of a measurement probe. In optical interferometry, a probe consisting of $N$ entangled photons provides up to a $\sqrt{N}$ enhancement in phase sensitivity compared to a classical probe of the same energy. Here, we employ high-gain parametric down-conversion sources and photon-number-resolving detectors to perform interferometry with heralded quantum probes of sizes up to $N=8$ (i.e. measuring up to 16-photon coincidences). Our probes are created by injecting heralded photon-number states into an interferometer, and in principle provide quantum-enhanced phase sensitivity even in the presence of significant optical loss. Our work paves the way towards quantum-enhanced interferometry using large entangled photonic states.

description: Despite their strain on government and donor budgets, fertilizer subsidies have once again become popular policy tools in several Sub-Saharan Africa countries as a potential way to increase yields in staple crops like maize. Policy makers often assume that farmers who receive the subsidy will achieve yield responses that are similar to those obtained by farmers who pay commercial prices for the input. This notion has not been verified empirically. Our study uses panel data from Malawi, a country that recently implemented a fertilizer subsidy program, to compare maize yield response to fertilizer from farmers who received subsidized fertilizer with yield responses from those who paid commercial prices for the input. Descriptive results indicate that maize plots using commercial fertilizer obtain higher yields per kilogram of fertilizer than maize plots that used subsidized fertilizer. Conversely, the results obtained using a fixed-effects estimator indicate that when other factors are controlled for, maize plots that use subsidized fertilizer obtain a higher yield response than other plots. The results seems to be influenced by a group of farmers who used no fertilizer before the subsidy program began, but used subsidized fertilizer after the program was implemented. This group of farmers obtained significantly higher yields in the year when they receive the subsidy than did the rest of the farmers in the sample during that year. These findings indicate that in order to be effective, government officials should specifically target fertilizer subsidies to farmers who lack access to commercial markets or would not otherwise find it profitable to purchase the input.

As a byproduct, the non-strange charmed mesons including D'1(2427) and D*(2637) were analyzed also.

description: We study properties of flux vacua in type IIB string theory in several simple but illustrative models. We initiate the study of the relative frequencies of vacua with vanishing superpotential W=0 and with certain discrete symmetries. For the models we investigate we also compute the overall rate of growth of the number of vacua as a function of the D3-brane charge associated to the fluxes, and the distribution of vacua on the moduli space. The latter two questions can also be addressed by the statistical theory developed by Ashok, Denef and Douglas, and our results are in good agreement with their predictions. Analysis of the first two questions requires methods which are more number-theoretic in nature. We develop some elementary techniques of this type, which are based on arithmetic properties of the periods of the compactification geometry at the points in moduli space where the flux vacua are located.

Effect of literature-based instruction on ESL acquisition rates

Publisher: name: University of British Columbia
Year: 2009

description: In light of research on bilingual education, this thesis examines English as a second language instructional methodologies that prevail in private, international ESL schools with an adult clientele. Notably, the current state of the international ESL industry does not reflect key advances in thinking about ESL teaching and learning. For example, the present emphasis on standardized testing as a gatekeeper of social, academic, and economic advancement has persuaded many private international ESL schools to adopt a grammar-based, communicative model of instruction in the understanding that such an approach is most efficacious in preparing students for success on exams. This study, however, suggests that a variety of factors contribute to student success in these settings, not the least of which is cultural immersion, which enhances reciprocal learning processes and contextualizes learner input. Literature is posited as furthering this process through textual immersion. Employing methods that promote textual immersion and creative response to literature encourages instructors and students to set aside the biased notion that there is a correct standard of English usage, and to explore, instead, the interactive possibilities inherent in meaning-making and cultural expression. In this study, it is hypothesized that integration of literature into ESL pedagogy increases basic grammatical knowledge and enhances cultural sensitivities. An experimental design was used to compare the results of a literature-enhanced, contentrich curriculum with a standardized, grammar-focused curriculum (Soars and Soars, 2003). With an alpha level of .05, findings suggest the null hypothesis for significant variation in acquisition rates dependent on curriculum, according to standardized test scores (Harrison and Kerr, 1996).

description: We report a promising candidate for a distant supercluster at z $\sim 1.1$ in the Dark Energy Survey Science Verification data. We examine smoothed semi-3D galaxy density maps in various photo-z slices. Among several overdense regions, in this work we report the most significant one as having a $3σ$ overdensity at a redshift of $\sim1.1$, over a $\sim160$ Mpc scale, much larger than the regular cluster scale (several Mpc). The shape of the supercluster is not circular in the sky projection. Therefore, we regard the point of maximum overdensity as the center for quantitative measurements. Two different estimates suggest the mass of the supercluster to be $1.37\substack{+1.31 \\ -0.79} \times 10^{17} M_{\odot}$, more than one order more massive than regular galaxy clusters. Except for protosuperclusters found with emission-line galaxies, this could be the most distant supercluster to date defined by regular galaxies. A spectroscopic confirmation would make this a very interesting object for cosmology. We discuss the possible implications of such a massive structure for $Λ$CDM cosmology.

description: Though brand loyalty has been studied extensively in the marketing literature, the relationship between brand loyalty and equilibrium pricing strategies is not well understood. Designing sales pricing strategies involves two key decisions: the percentage reduction in price from the existing price point, and the number or frequency of promotions within a category or for a specific product. These decisions, in turn, are critically dependent upon how many consumers can be convinced to switch to a brand by temporarily reducing its price, and how many are instead brand loyal. Theoretical models of how the size and strength of brand loyalty influence optimal promotion strategies have been developed, but there are no rigorous tests of their hypotheses. We test how brand loyalty impacts promotion strategies for a frequently purchased consumer package good category. Our results largely confirm that retailers often promote many brands simultaneously and that depth and breadth can be complementary.

description: Using the special value at $u=1$ of Artin-Ihara $L$-functions, we associate to every $\mathbb{Z}$-cover of a finite connected graph a polynomial which we call the \emph{Ihara polynomial}. We show that the number of spanning trees for the finite intermediate graphs of such a cover can be expressed in terms of the Pierce-Lehmer sequence associated to a factor of the Ihara polynomial. This allows us to express the asymptotic growth of the number of spanning trees in terms of the Mahler measure of this polynomial. Specializing to the situation where the base graph is a bouquet or the dumbbell graph gives us back previous results in the literature for circulant and $I$-graphs (including the generalized Petersen graphs). We also express the $p$-adic valuation of the number of spanning trees of the finite intermediate graphs in terms of the $p$-adic Mahler measure of the Ihara polynomial. When applied to a particular $\mathbb{Z}$-cover, our result gives us back Lengyel's calculation of the $p$-adic valuations of Fibonacci numbers.

description: During the 1990s, demand for organic products increased on average by 20% each year. This growth in demand fueled growth in organic crop acreage. Between 1992 and 2005, organic cropland more than quadrupled, going from 403,400 acres to just over 1.7 million acres (USDA, 2008). Demand is predicted to increase annually by an additional 9 to 16% through 2010 (Dimitri and Oberholtzer, 2005). This further increase in demand will lead to an additional expansion of organic acreage, increasing the heterogeneity of agricultural regions and increasing the interaction that occurs between conventional and organic farms as they more frequently share the same regional landscape. Sharing the same landscape implies that they share pest and natural enemy populations. The movement of these organisms links farms within a region, potentially causing one grower’s pest control decisions to impact other growers. This paper examines these interactions. The analysis focuses on one organic and one conventional profit-maximizing grower. One pest and one natural enemy population connect the time periods in the model, and the movement of these populations connects the grower’s fields, creating a spatial-dynamic model. The analysis compares the privately optimal levels of pest control on the neighboring farms with the socially optimal levels of pest control. This comparison will illuminate situations when private decisions lower the region’s total profits via negative externalities created by the movement of insects. The model examines how these externalities differ under different population dynamics.

description: Cold dark matter haloes are populated by high-density structures with sharply-peaked profiles known as caustics which have not yet been resolved by 3-dimensional numerical simulations. Here, we derive semi-analytic expressions for the density profiles near caustics in haloes which form by self-similar accretions of dark matter with infinitesimal velocity dispersion. A simple rescaling shows that similarly to the case of absolutely cold medium these profiles are universal: they are valid for all caustics and irrespective of physical parameters of the halo. We derive the maximum density of the caustics and show that it depends on the velocity dispersion and the caustic location. We show that both the absolute and relative thickness of the caustic monotonically decrease toward the center of the halo while the maximum density grows. This indicates that the radial component of the thermal velocities decreases in the inner streams, i.e. the collisionless medium cools down in the radial direction descending to the center of the halo. Finally, we demonstrate that there can be a significant contribution to the emission measure from dark matter particle annihilation in the caustics.

description: We consider the problem of black-box function optimization over the boolean hypercube. Despite the vast literature on black-box function optimization over continuous domains, not much attention has been paid to learning models for optimization over combinatorial domains until recently. However, the computational complexity of the recently devised algorithms are prohibitive even for moderate numbers of variables; drawing one sample using the existing algorithms is more expensive than a function evaluation for many black-box functions of interest. To address this problem, we propose a computationally efficient model learning algorithm based on multilinear polynomials and exponential weight updates. In the proposed algorithm, we alternate between simulated annealing with respect to the current polynomial representation and updating the weights using monomial experts' advice. Numerical experiments on various datasets in both unconstrained and sum-constrained boolean optimization indicate the competitive performance of the proposed algorithm, while improving the computational time up to several orders of magnitude compared to state-of-the-art algorithms in the literature.

description: Aims. We intend to spatially and spectrally resolve the [O I] emission region in two nearby Herbig stars. Methods. We present high-resolution (R = 80,000) VLT/UVES echelle spectra of the [O I] 6300A line in the Herbig Ae/Be stars HD 97048 and HD 100546. Apart from the spectral signature, also the spatial extent of the [O I] emission region is investigated. For both stars, we have obtained spectra with the slit positioned at different position angles on the sky. Results. The [O I] emission region of HD 100546 appears to be coinciding with the dust disk, its major axis located at 150+/-11 degrees east of north. The SE part of the disk moves towards the observer, while the NW side is redshifted. The [O I] emission region rotates counterclockwise around the central star. For HD 97048, the position angle of the emission region is 160+/-19 degrees east of north, which is the first determination of this angle in the literature. The southern parts of the disk are blueshifted, the northern side moves away from us. Our data support the idea that a gap is present at 10AU in the disk of HD 100546. Such a gap is likely planet-induced. We estimate the mass and orbital radius of this hypothetical companion responsible for this gap to be 20 Jupiter masses and 6.5 AU respectively. Conclusions. Based on temporal changes in the [O I] line profile, we conclude that inhomogeneities are present in the [O I] emission region of HD 100546. These ``clumps'' could be in resonance with the suggested companion, orbiting the central star in about 11 yr. If confirmed, these observations could point to the existence of an object straddling the line between giant planet and brown dwarf in a system as young as 10 million years.

title: Entrelacs littérature / musique : ré-union langagière des arts dans les romans d’Anne-Lise Grobéty et Alice Rivaz

description: Alice Rivaz et Anne-Lise Grobéty, auteures suisses romandes, se caractérisent par des écritures empreintes d’une grande musicalité. Les notions de rythme et de scansion sont au cœur de leurs projets littéraires, il s’agit d’insuffler une scansion particulière à l’écriture – et donc à la lecture – afin de permettre à la langue de signifier autrement. Leurs œuvres romanesques recèlent de nombreuses intermédialités entre littérature écrite et musique sonore. De ce dialogue naissent des poétiques tout à fait intéressantes, qui convoquent les mots comme autant d’éléments sonores : jouant de la découpe des phrases, de leurs mises en page ou encore des syllabes qui les composent, elles en viennent à hybrider les arts. Si la musique tient une place importante en tant que topos, c’est surtout au niveau des textes eux-mêmes que la musique prend tout son sens : elle vient littéralement compléter le scripturaire, rendant possible l’inscription du langage. Ainsi, nous consacrerons notre étude aux écritures de ces auteures qui en viennent à articuler texte et musique, faisant ainsi advenir le langage dans la langue et donnant ainsi un accès plus direct aux émotions et aux ressentis.

description: In this work, we employ the Synthetic Minority Oversampling Technique (SMOTE) to generate instances of the minority class of an imbalanced Coronary Artery Disease dataset. We firstly analyze the public dataset Z -- Alizadeh Sani, a dataset used for non-invasive prediction of CAD. We perform feature selection to exclude attributes unrelated to Coronary Artery Disease risk. The generation of new samples is performed using SMOTE, a technique commonly employed in machine learning tasks. We design Artificial Neural Networks, Decision Trees, and Support Vector Machines to classify both the original dataset and the augmented. The results demonstrate that data augmentation may be beneficial in specific cases, but it is not a panacea, and its application in a specific dataset should be carefully examined.

description: We describe an optical bench in which we lock the relative frequencies or phases of a set of three lasers in order to use them in a cold atoms interferometry experiment. As a new feature, the same two lasers serve alternately to cool atoms and to realize the atomic interferometer. This requires a fast change of the optical frequencies over a few GHz. The number of required independent laser sources is then only 3, which enables the construction of the whole laser system on a single transportable optical bench. Recent results obtained with this optical setup are also presented.

description: In this paper we discuss the optimizing compilation of Constraint Handling Rules (CHRs). CHRs are a multi-headed committed choice constraint language, commonly applied for writing incremental constraint solvers. CHRs are usually implemented as a language extension that compiles to the underlying language. In this paper we show how we can use different kinds of information in the compilation of CHRs in order to obtain access efficiency, and a better translation of the CHR rules into the underlying language, which in this case is HAL. The kinds of information used include the types, modes, determinism, functional dependencies and symmetries of the CHR constraints. We also show how to analyze CHR programs to determine this information about functional dependencies, symmetries and other kinds of information supporting optimizations.

title: « Si de mi baja lira tanto pudiese el son… » Le chant d’Orphée et les poètes de la Renaissance
Creators: name: Delahaye-Grelois, Séverine
Publisher: name: Savoirs en prisme

description: La poésie et la musique de la Renaissance étaient pensées et pratiquées ensemble, comme les deux volets d’un même art dont l’unité est représentée par la figure d’Orphée, employée par le poète castillan Garcilaso de la Vega, entre autres pour énoncer son programme poétique. La métrique latine est la base du traitement du rythme musical dans le De musica libri septem (1577) de Francisco de Salinas. Une lecture attentive du livre V montre comment un assemblage incorrect de pieds était considéré comme une dissonance, analogue en tous points avec la dissonance harmonique. Une comparaison avec des vers contemporains montre que ces dissonances étaient employées par les poètes exactement de la même façon que les dissonances harmoniques par les madrigalistes, pour expliquer des idées précises. On peut donc véritablement dire qu’il y avait de la musique dans la poésie de la Renaissance. De telles dissonances rythmiques préparaient la performance musicale, comme le confirment des exemples pris chez Monteverdi et Gesualdo.
