title: Liquidity, Redistribution, and the Welfare Cost of Inflation
Creators: name: Chiu, Jonathan
name: Molico, Miguel
Publisher: name: Bank of Canada
Year: 2007

description: This paper studies the long run welfare costs of inflation in a micro-founded model with trading frictions and costly liquidity management. Agents face uninsurable idiosyncratic uncertainty regarding trading opportunities in a decentralized goods market and must pay a fixed cost to rebalance their liquidity holdings in a centralized liquidity market. By endogenizing the participation decision in the liquidity market, this model endogenizes the responses of velocity, output, the degree of market segmentation, as well as the distribution of money. We find that, compared to the traditional estimates based on a representative agent model, the welfare costs of inflation are significantly smaller due to distributional effects of inflation. The welfare cost of increasing inflation from 0% to 10% is 0.62% of income for the U.S. economy and 0.20% of income for the Canadian economy. Furthermore, the welfare cost is generally non-linear in the rate of inflation, depending on the endogenous responses of the liquidity market participation to inflation and liquidity management costs.
description: Les auteurs étudient les coûts à long terme de l'inflation au plan du bien-être dans un modèle avec fondements microéconomiques où les échanges s'accompagnent de frictions et d'une gestion des liquidités coûteuse. Les agents sont confrontés à une incertitude idiosyncratique inassurable qui touche les occasions d'échange sur un marché décentralisé des biens, et ils doivent rééquilibrer leurs avoirs liquides à coût fixe sur un marché centralisé des liquidités. En conférant un caractère endogène à la décision des agents de participer au marché des liquidités, les auteurs permettent au modèle d'endogénéiser les réactions obtenues pour la vitesse de circulation, la production, le degré de segmentation des marchés et la distribution de la monnaie. Ils constatent que, par rapport aux estimations conventionnelles des modèles à agent représentatif, les coûts de l'inflation sur le bienêtre se trouvent nettement réduits par les effets de répartition de l'inflation. Ainsi, la hausse du taux d'inflation de 0 à 10 % se solde, en termes de bien-être, par une perte de revenus de 0,62 % pour l'économie américaine et de 0,20 % pour l'économie canadienne. De plus, la perte de bienêtre n'évolue souvent pas dans les mêmes proportions que le taux d'inflation, mais dépend de l'effet endogène qu'a l'inflation sur la participation au marché des liquidités ainsi que des frais de gestion des liquidités.

description: In the beginning, the retail industry’s target was to offer low prices to consumers thanks to large quantities ordered from wellknown brands, allowing better prices than in traditional retail businesses. Little by little, the part played by retailers (grocery stores) changed and now it has been 30 years since retailers have not only played an ordinary retailer’s role, but are also managers of their own brands, named store brands and more commonly Private Labels (PL). For the great majority of products, one does not only find national brands (NB) on store shelves. Consumers may also purchase the retailer’s brand, which exists in different forms (see frame 1). The first part of this text will concern the economic origin of Private Labels and reveal some of the objectives of retailers with the development of Private Labels. The second part will turn to the consumers, trying to find out their characteristics and choice determinants when buying a PL. Lastly, we shall take an interest in the reaction of well-known brand producers, especially through NB prices, against PL development.

Year: 2007

description: In this paper we look at the relative information content of cash and futures prices for Canadian Government bonds.

We follow the information-share approaches introduced by Hasbrouck (1995) and Harris et al (1995), applying the techniques in Gonzalo-Granger (1995), to evaluate the relative contributions of trading in the cash and futures markets to the price discovery process. Both approaches estimate a vector error correction model that permits the separation of long-run price movements from short-run market microstructure effects. As well, we follow Yan and Zivot (2004) who introduce size measures of a market's adjustment to a new equilibrium during the price discovery process. We find that, on an average day, just over 70% of price discovery occurs on the futures market where bid-ask spreads are lower and trading activity is higher. The size of the responses to shocks and the time taken to adjust to a new equilibrium are found to be significantly larger for the cash market.
description: Les auteurs examinent les contenus informatifs respectifs des prix au comptant et à terme des obligations du gouvernement canadien.

Pour évaluer les contributions respectives des marchés au comptant et à terme au processus de découverte des prix, Chung, Campbell et Hendry recourent aux méthodes élaborées par Hasbrouck (1995) et par Harris et autres (1995), ces derniers s'inspirant des techniques qu'utilisent Gonzalo et Granger (1995). Les deux méthodes sont appliquées à un modèle vectoriel à corrections d'erreurs qui permet de distinguer les mouvements de prix à long terme des effets à court terme liés à la microstructure des marchés. En outre, dans l'esprit des travaux de Yan et Zivot (2004), les auteurs mesurent l'ampleur des déviations que le marché enregistre par rapport aux nouvelles valeurs d'équilibre durant le processus de découverte des prix. Ils constatent qu'au cours d'une journée ordinaire, le marché à terme, sur lequel les écarts acheteur-vendeur sont plus bas et l'activité est plus grande, contribue à hauteur d'un peu plus de 70 % à la découverte des prix. L'ampleur des réactions aux chocs et la vitesse de retour à l'équilibre sont nettement plus élevées sur le marché au comptant.
title: Family Values: Ownership Structure, Performance and Capital Structure of Canadian Firms

description: This study examines how family ownership affects the performance and capital structure of 613 Canadian firms using a panel dataset from 1998 to 2005. In particular, we distinguish the effect of family ownership from the use of control-enhancing mechanisms. We find that freestanding family-owned firms with a single share class have similar market performance than other firms based on Tobin's q ratios, superior accounting performance based on ROA, and higher financial leverage based on debt-to-total assets. By contrast, family-owned firms that use dual-class shares have valuations that are lower by 17% on average relative to widely-held firms, despite having similar ROA and financial leverage. Finally, concentrated ownership by either a corporation or a financial institution does not significantly affect firm performance.
description: En se fondant sur un ensemble de données de panel relatif à 613 entreprises canadiennes et allant de 1998 à 2005, les auteurs examinent comment le fait qu'une entreprise soit la propriété d'une famille influe sur sa rentabilité et la structure de son capital. Ils s'attachent en particulier à bien distinguer les rôles respectifs de ce facteur et des mécanismes de renforcement du contrôle. Les auteurs constatent que les entreprises familiales indépendantes qui émettent une seule catégorie d'actions sont aussi bien évaluées que les autres (d'après le ratio q de Tobin), plus rentables (d'après le rendement de l'actif) et plus endettées (d'après le ratio de la dette à l'actif total). À l'opposé, les entreprises familiales dont les actions sont assorties de droits de vote différents sont sous-évaluées en moyenne de 17 % par rapport aux entreprises à capital dispersé, même si le rendement de leur actif et leur endettement sont semblables à ceux de ces entreprises. Enfin, le fait d'appartenir à une autre société ou à une institution financière n'influe pas de façon significative sur les résultats.

description: The redshift distribution of flat-spectrum radio sources with 5 GHz flux densities S>5 mJy is a key component in using current radio lens surveys to probe the cosmological model. We have constructed the first flat-spectrum radio sample in the flux density range 3-20 mJy. Our new sample has 33 sources; we have determined the redshifts of 14 of these (42% complete). The low mean redshift, ~0.75, of our faintest sample needs to be confirmed by further observations to improve the sample completeness. We also increased the redshift completeness of several surveys of brighter flat-spectrum sources. While the mean redshift, ~1.1 of flat-spectrum samples fainter than 1 Jy is nearly constant, the fraction of the sources identifiable as quasars steadily drops from ~80% to ~10% as the flux density of the sources decreases.

Which is the Right Reference Surface Compression Value for Heat Treated Glass?

Publisher: name: Challenging Glass Conference Proceedings
Year: 2018

description: The paper correlates the data recorded in Stazione Sperimentale del Vetro, in many years. The aim is to define a correlation between the following parameters in heat treated glass: 1) bending strength tested according EN 1288-3 ; 2) fragmentation tested according relevant Standards [EN 1863-1 2004, EN12150-1 2015, EN 14179-1 2016]; 3) surface compression stress measured with laser Gasp [ASTM C1279 2013]. For heat strengthened glass the fragmentation correlation due to the different crack path ("island" fragments instead of small fragments) is only related to conformity: Y/N. The research is the development of the previous ones [Schiavonato et al. 2005, Mognato et al. 2011] carried out at Stazione Sperimentale Vetro, increasing the experimental data (up to 2017)considering in detail the emissivity of coated glass and extending also to enamelled glass. The correlation between surface compression stress and mechanical strength and fragmentation is relevant for the manufacturer, who may use surface pre-stress measurement as a means of product control.

description: Gene expression has a stochastic component owing to the single molecule nature of the gene and the small number of copies of individual DNA binding proteins in the cell. We show how the statistics of such systems can be mapped on to quantum many body problems. The dynamics of a single gene switch resembles the spin boson model of a two site polaron or an electron transfer reaction. Networks of switches can be approximately described as quantum spin systems by using an appropriate variational principle. In this way the concept of frustration for magnetic systems can be taken over into gene networks. The landscape of stable attractors depends on the degree and style of frustration, much as for neural networks. We show the number of attractors, which may represent cell types, is much smaller for appropriately designed, weakly frustrated stochastic networks than for randomly connected networks.

description: In this study, fourteen celastrol derivatives (1–14) were synthesised by esterification of celastrol at the 29th position. The in vitro anticancer activity of them was determined by the MTT assay. All the synthetic compounds showed significant antiproliferative activity against six cancer cells, with IC50 of the submicron molar level. The most promising compound (2) blocked the cell cycle in the G2 phase and inhibited the expression of VEGF and MMP-9 in gastric cancer cell line MGC-803. In flow cytometry analysis, compound 2 induced cancer cell apoptosis in a dose-dependent manner. In the mouse tumour xenograft model, compound 2 showed significant anti-tumour activity in vivo at the dosage of 2.5 mg/kg and 1 mg/kg, with a higher inhibition rate than 5-FU (10 mg/kg). What’s more, the anticancer mechanism involved in the inhibition of VEGF and the toxicity evaluation of compound 2 were also investigated.

description: Circular RNA (circRNA) is a novel star factor in the research of ocular diseases including cataract and the most common postoperative complication posterior capsule opacification (PCO). Hsa_circRNA_0060640 (circ_0060640) is an age-related cataract-related circRNA. However, its role in cataractogenesis is unrevealed yet. PCO in vitro model was established in human lens epithelium cells (hLECs) induced by transforming growth factor-beta2 (TGF-β2). RNA and protein expressions were respectively detected by quantitative PCR and western blotting. Direct interaction between two RNAs was predicted by Starbase tool and confirmed by dual-luciferase reporter assay. MTS and EdU assays measured cell proliferation; Transwell, starch wound and western blotting assays evaluated cell motility and epithelial-mesenchymal transition (EMT). Circ_0060640 expression is higher in anterior lens capsule tissues from human cataractous eyes and TGF-β2-stimulated hLECs cells line SRA01/04. RNA interference of circ_0060640 could prevent SRA01/04 cells from TGF-β2-induced cell proliferation, migration and invasion, accompanied with decreased N-cadherin and α-smooth muscle actin and increased E-cadherin. Mechanistically, circ_0060640 directly controls microRNA (miR)-214-3p expression and then regulates gene expression of collagen type I alpha2 chain (COL1A2). Notably, COL1A2 inhibition is underlying the protective role of circ_0060640 silencing and miR-214-3p ectopic expression in TGF-β2-stimulated SRA01/04 cells. Circ_0060640 is a novel cataract-related gene and its silencing could block TGF-β2-evoked hLECs proliferation, motility and EMT in vitro via targeting miR-214-3p-COL1A2 axis. Therefore, targeting circ_0060640 via RNA interference might be a treatment strategy for PCO development.
Mistral Tower: Value of System Design, Manufacturing and Installation in Cold Bent SSG Units

description: Use of cold-bent and warped glass units in unitized curtain walling is becoming a state-of-the art application. During the last years, such a global trend has challenged the design and engineering of glass units, frame elements as well as bonding joints in Structural Sealant Glazing (SSG) applications and has pushed for the investigation of material performance and calculation concepts, beyond available standards and guidelines. It is clear today that in SSG systems cold bending retention forces and differential displacements play a major role in the system design and need to be properly controlled. With reference to SSG joints, investigation has focused on proposing simplified equations to evaluate cold bending stress and studying relaxation and creeping behavior of Sikasil® structural silicones to exploit material performance beyond standard limits. Such investigation process allows identifying where opportunities for systems optimizations are and clarifies that effective cold-bending solutions cannot be uncoupled from new principles of system design, pre-manufacturing and installation. The development of Mistral Tower in Izmir offers the chance to evaluate in detail the impact of different frame solutions in combination with different production and installation methods and is used to present to system designers and façade producers valuable options and guidelines for approaching design of cold-bent units effectively. The use of slim adapter frame bonded to glass units and free to slide into load-bearing frame represents the basic requirement to limit cold bending effects on SSG joints, while minimizing production efforts. Valuable optimization results can be further achieved if bonding on either pre-shaped frame or pre-shaped frame/glass assembly is possible or if cold-bending stress can be limited in time by a clever production method in controlled conditions. Advanced FE analysis simulating SSG joints by hyperelastic material law validate preliminary stress evaluation, criteria selection for unit manufacturing and final design choices in Mistral Tower construction.

description: This paper studies the steady-state costs of inflation in a general-equilibrium model with real per capita output growth and staggered nominal price and wage contracts.

Our analysis shows that trend inflation has important effects on the economy when combined with nominal contracts and real output growth. Steady-state output and welfare losses are quantitatively important even for low values of trend inflation. Further, we show that nominal wage contracting is quantitatively more important than nominal price contracting in generating these losses. This important result does not arise from price dispersion per se but from an effect of nominal output growth on the optimal markup of monopolistically competitive labour suppliers. We also demonstrate that accounting for productivity growth is important for calculating the welfare costs of inflation. Indeed, the presence of two percent productivity growth increases the welfare costs of inflation in our benchmark specification by a factor of four relative to the nogrowth case.
description: Les auteurs étudient les coûts de l'inflation en régime permanent au moyen d'un modèle d'équilibre général dans lequel le taux de croissance réel de la production par habitant est positif et qui intègre des contrats échelonnés de prix et de salaires.

L'analyse montre qu'une inflation tendancielle positive a des effets considérables sur l'économie lorsqu'elle est jumelée à des contrats rédigés en termes nominaux et à une croissance réelle de la production. Même faible, l'inflation tendancielle entraîne une baisse substantielle du niveau de la production et du bien-être en régime permanent. Les auteurs démontrent également que cette diminution tient davantage à l'existence de contrats salariaux qu'à celle de contrats de prix. Cet important résultat ne découle pas de la dispersion des prix en soi, mais de l'incidence de la croissance nominale sur le choix de la marge bénéficiaire exigée par les offreurs de travail en situation de concurrence monopolistique. Par ailleurs, les auteurs établissent que la prise en compte de la croissance de la productivité importe pour le calcul des retombées négatives de l'inflation sur le bien-être; selon leurs calculs, un taux de croissance de 2 % de la productivité multiplie par quatre les coûts de l'inflation dans la spécification type du modèle, par rapport au cas où la croissance de la production est nulle.

description: Post-AGB binaries are surrounded by circumbinary disks of gas and dust that are similar to protoplanetary disks found around young stars. We aim to understand the structure of these disks and identify the physical phenomena at play in their very inner regions. We want to understand the disk-binary interaction and to further investigate the comparison with protoplanetary disks. We have conducted an interferometric snapshot survey of 23 post-AGB binaries in the near-infrared (H-band) using VLTI/PIONIER. We have fitted the multiwavelength visibilities and closure phases with purely geometrical models with an increasing complexity in order to retrieve the sizes, temperatures and flux ratios of the different components All sources are resolved and the different components contributing to the H-band flux are dissected. The environment of these targets is very complex: 13/23 targets need models with thirteen or more parameters to fit the data. We find that the inner disk rims follow and extend the size-luminosity relation established for disks around young stars with an offset toward larger sizes. The measured temperature of the near-infrared circumstellar emission of post-AGB binaries is lower (Tsub~1200K) than for young stars, probably due to a different dust mineralogy and/or gas density in the dust sublimation region. The dusty inner rims of the circumbinary disks around post-AGB binaries are ruled by dust sublimation physics. Additionally, a significant amount of the circumstellar H-band flux is over-resolved (14 targets have more than 10% of their non-stellar flux over-resolved) hinting for more structure from a yet unknown origin (disk structure or outflow). The amount of over-resolved flux is larger than around young stars. Due to the complexity of these targets, interferometric imaging is a necessary tool to reveal the interacting inner regions in a model-independent way.

description: The French retail industry is the most regulated in Europe. However, the recent Dutreil law, which took effect on January 1st 2006, lightens the regulation reforming the previous 1996 Galland law. The purpose of this reform is to lower retail prices of products sold in supermarkets, especially the prices of national brands. The research work presented here help define better the mechanisms that facilitate the rise, or conversely the drop, in retail industry prices. The balance of power between suppliers and retailers and the regulations play a crucial part in the understanding of these mechanisms. The analyses associate theoretical and empirical contributions.

description: The owner of a 1970s, 24-story commercial office tower in Ottawa, Canada sought to rejuvenate their main lobby with a new glass entry wall. The wall’s purpose is to provide a notable, grand entryway for the re-development of a commercial podium on a main thoroughfare. The final design featured a 12 m tall by 35 m long curving glass fin wall. The height of the wall is broken up into two sections. The first is a 9 m tall section between the ground floor and a third-floor terrace that provides the main building with a new front entrance, including a double-height space. The second is a cantilevered 3 m tall balustrade that creates a new third floor terrace. The glass fins between the ground floor and third floor terrace are continuous, triple-laminated panels free of splices. The curved panels have a 30 m curvature radius and feature a ceramic frit to prevent bird strikes and promote environmental sensitivity. In addition, the panels are insulated glass units (IGUs) with a low-emissivity coating (low-e) to meet the City of Ottawa’s energy standards and the expected interior comfort of top tier retail and office space within the city. Furthermore, the glass panels are supported at discrete points, so the team used a composite resin as the laminate for the interior and exterior lites to maintain the cold bent curvature radius.

Thermally Curved Glass - Research and Standardisation of the Four-Point Bending Test

description: Research has shown that the general approach to determine the bending strength of thermally curved glass with the aid of the four-point bending test for flat glass according to EN 1288-3 is applicable. At the moment, however, there is no statutory method available for directly extrapolating the breaking strain from the breaking load without the use of expensive strain gauges. Such a method is developed by means of an experimental and numerical study in a research project between the Bundesverband Flachglas e.V. (Federal Flat Glass Association) and the Fachverband Konstruktiver Glasbau e.V. (Professional Association Structural Glass Constructions), the Institute of Building Construction at the Technische Universität Dresden and four glass bending specialists. Moreover, it will provide the basis for testing cylindrically curved glass of any bending radius. The project partners have already submitted a proposal for a new standard to the Deutsches Institut für Normung e.V. (German Institute for Standardisation). The paper gives the theoretical background for determining the strength of flat glass according to EN 1288‑3 and quantifies the additional effects for the testing of thermally curved glass. Furthermore, the testing method of the executed experimental study on thermally curved glass is described. The range of parameters for the tested specimens included the glass thickness from 3 mm to 12 mm and the bending radii from 400 mm to 2000 mm. We recorded the strain at selected points at the tensioned side and the input force for each specimen. The measured relation between strain and load validates a numerical model, which is able to depict the actual two-dimensional stress distribution for thermally curved glass and includes non-linear aspects. The model allows for the determination of correction factors. With those, the bending strength of thermally curved glass can be calculated by measuring merely the input force during the four-point bending tests. The correction factors are summarised in charts depending on the radius and the thickness of the glass sample.

The Effects of Cold Warping on Glass Stiffness
Creators: name: Bensend, Austin
Publisher: name: Challenging Glass Conference Proceedings
Year: 2018

description: Significant progress has been made during the past two decades to advance the use of cold warped glazing (glass that has been elastically twisted out of plane) to achieve architectural vision. As with most new technologies, a full understanding of the mechanics of elastic cold warping has lagged its adoption and increasing specification for use in new construction. As a contractor whose aim is to turn vision into reality, Enclos has been invested in research and development related to the structural and performance implications of cold warped glazing. One of the most recent discoveries from this work at Enclos has been to relate cold warping of glass to its effect on plate stiffness. In particular, transverse stiffness to resist load may be negatively affected by the operation of cold warping glass supported by a perimeter frame. This loss in stiffness has been observed in cold warped glass when compared to flat glass of equal size and thickness. Recent work at Enclos indicates deflection due to transverse load increases with an increasing degree of warping. This phenomenon is especially pronounced for thin plates that resist load through significant large-deformation, non-linear plate behavior. As the degree of warp increases, the loss of stiffness becomes increasingly apparent, to the point at which the glass buckles. As a result of the warping operation, compressive membrane stresses are generated in the center region of the glass. These compressive stresses counteract the tension that normally arises during large-deformation plate behavior and that contributes to its deflection performance. As such, a membrane compression due to warping leads to the loss in stiffness when membrane effects appreciably contribute to overall bending stiffness (as they do in plates that fall within the large-deflection regime of bending). An exploration of this phenomena using a series of finite element tests, coupled with observations from previous testing are the basis for these findings.

description: The wine market has experienced major transformations in the past thirty years, with a consumption collapse per capita in the historical Southern European producing countries and the emergence of new actors in America and Oceania. The result of this was a structural gap between supply and demand, generating wine-growing prices and income instability, mainly in the European Union and, more recently, in Australia. This alteration goes with a restructuring of the supply, with the emergence of an oligopoly with fringes1 already observed in other agrifood sectors. A dominant group of powerful multinational firms has settled in, based on a high-scale strategy, strong marketing of products and the capture of distribution networks. This strategy finds its financial resources in the growing financialisation of corporate governance. It appeals to public authorities, especially European ones, for a reform of the institutional sector-based framework.

description: We report the discovery of pulsed X-ray emission from the compact object CXOU J112439.1-591620 within the supernova remnant (SNR) G292.0+1.8 using the High Resolution Camera on the Chandra X-ray Observatory. The X-ray period (P=0.13530915 s) is consistent with extrapolation of the radio pulse period of PSR J1124-5916 for a spindown rate of dP/dt=7.6E-13 s/s. The X-ray pulse is single peaked and broad with a FWHM width of 0.23P (83 degrees). The pulse-averaged X-ray spectral properties of the pulsar are well described by a featureless power law model with an absorbing column density, N_H= 3.1E21 atoms/cm^2; photon index, gamma = 1.6; and unabsorbed 0.3-10 keV band luminosity, L_X = 7.2E32 erg/s. We plausibly identify the location of the pulsar's termination shock. Pressure balance between the pulsar wind and the larger synchrotron nebula, as well as lifetime issues for the X-ray-emitting electrons, argues for a particle- dominated PWN that is far from the minimum energy condition. Upper limits on the surface temperature of the neutron star are at, or slightly below, values expected from ``standard'' cooling curves. There is no optical counterpart to the new pulsar; its optical luminosity is at least a factor of 5 below that of the Crab pulsar.

description: Email messages have been an important mode of communication, not only for work, but also for social interactions and marketing. When messages have time sensitive information, it becomes relevant for the sender to know what is the expected time within which the email will be read by the recipient. In this paper we use a survival analysis framework to predict the time to open an email once it has been received. We use the Cox Proportional Hazards (CoxPH) model that offers a way to combine various features that might affect the event of opening an email. As an extension, we also apply a mixture model (MM) approach to CoxPH that distinguishes between recipients, based on a latent state of how prone to opening the messages each individual is. We compare our approach with standard classification and regression models. While the classification model provides predictions on the likelihood of an email being opened, the regression model provides prediction of the real-valued time to open. The use of survival analysis based methods allows us to jointly model both the open event as well as the time-to-open. We experimented on a large real-world dataset of marketing emails sent in a 3-month time duration. The mixture model achieves the best accuracy on our data where a high proportion of email messages go unopened.

description: The Beam Instrumentation group at CERN has developed a new scintillating fibre beam monitor for the measurement of secondary particle beams in the CERN Experimental Areas. The monitor has a simple design that stands out for its low material budget, vacuum compatibility, good performance, low cost, and ease of production. By using different read-out techniques the monitor can perform several functions, such as measurement of the profile, position and intensity of the beam, momentum spectrometry, generation of fast trigger signals, and measurement of the time-of-flight for particle identification. The monitor has been successfully commissioned in the recently created test beams of the CERN Neutrino Platform, where it has shown an excellent performance as described in the paper.

description: This paper focuses on a recently developed concept, in which glass is combined with timber to provide post-breakage strength and ductility. This combination allows for good post-breakage performance and overall robustness of timber-glass composite beams and wall elements, which has been reported in several publications. The application of timber-glass elements in practice, however, raises important issues related to structural fire performance. The paper elaborates on this issue and provides general information about the behavior of glass, timber and adhesives at elevated temperatures and under fire conditions. Furthermore, it presents ideas and strategies developed for potential application of timber-glass composites in practical situations. The paper presents also initial results from an on-going research project on fire performance of timber-glass composites.

title: Cyclical Behavior of Debt and Equity Using a Panel of Canadian Firms

description: We document the cyclical behavior of debt, equity, and retained earnings for different firm categories using firm-level Canadian data. There is evidence of both procyclical equity and debt issuance for all firm categories but the timing differs. In particular, there is strong evidence that equity issuance increases in anticipation of an expansion. During this phase, some substitution between debt and equity takes place. After the expansion has reached its peak, equity issuance starts to decrease and during this phase there is strong evidence of procyclical debt issuance and some substitution out of equity seems to take place. Retained earnings is procyclical except for small firms.
description: Au moyen de données recueillies à l'échelon de l'entreprise puis regroupées par taille d'entreprise, les auteurs étudient le comportement cyclique des émissions d'obligations et d'actions et des bénéfices non répartis des sociétés canadiennes. L'analyse de ces données indique que les émissions d'obligations et d'actions présentent un caractère procyclique peu importe la catégorie de taille examinée, mais qu'elles s'échelonnent différemment dans le temps. Elle révèle en particulier que le volume des actions émises augmente à l'approche d'une phase d'expansion, aux dépens de l'émission d'obligations. Passé le pic du cycle d'expansion, l'émission d'actions diminue et semble céder graduellement la place à l'émission d'obligations, dont le caractère procyclique se manifeste alors. Les bénéfices non répartis affichent un comportement procyclique, sauf dans le cas des petites entreprises.
Core Size Effect on the Vortex Quasiparticle Excitations in Overdoped $La_{2-x}Sr_xCuO_4$ Single Crystals

description: Low temperature specific heat has been measured for an overdoped $La_{2-x}Sr_xCuO_4$ (x = 0.22) single crystal. The quasiparticle density of states (DOS) in the mixed state is found to deviate from the predicted scaling law $C_{vol}=Hf(T/H^{1/2})$. However, this scaling behavior is nicely reconciled if one considers the normal core region ($ξ\approx$ 21$Å$) which gives small contribution to the total DOS. The radius of the core and other parameters derived are consistent with reported values. Our results suggest that there is no zero-bias conductance peak (ZBCP), which is predicted by the simple Bogoliubov de-Gennes theory in the vortex core of a d-wave superconductor.
