description: b Si-X, the Netherlands The C&A building in Eindhoven will be modernised and therefore UNStudio designed several glass structures for the building. One of these glass structures are four glass boxes of 5,5 meters wide and 7 meters high, which are floating in front of the existing façade. In addition, each glass box contains a work of light art designed by Arnout Meijer. LED strips illuminate the box from the inside, while the reflective film on the glass creates an unusual and striking effect. To optimize this effect no metal connections were allowed in the design. The size of 5,5 by 7 meters was exceeding every international standard format in the glass industry. ABT designed an ‘Origami’ glass box with glass panels glued together. This geometry solved the problem of the limited size of the panels and also made a more economic structural form. The glass panels are connected seamless with different type of glues. ABT made an extensive research for the right type of glues in cooperation with the university of Leuven. The glued connections are combined with glass notches; a new type of connection, inspired by timber connections and earlier research of stacked glass columns. FEM DIANA models showed that this is a promising way to connect glass structures. Sober thinking of the engineers about mechanical schemes solved the demand of UNStudio, seamless floating glass boxes. The result can be seen at the 18 September plein in Eindhoven.

title: Consumer Interest Rates and Retail Mutual Fund Flows
Creators: name: Sierra, Jesus
Publisher: name: Bank of Canada
Year: 2012

description: This paper documents a link between the real and financial sides of the economy. We find that retail equity mutual fund flows in Canada are negatively related to current and past changes in a component of the prime and 5-year mortgage rates that is uncorrelated with government rates. The effect is present when we control for other determinants of fund flows and is more pronounced for big and old funds. The results suggest that consumers’ investments in domestic equity mutual funds take time to respond to changes in interest rates, and that developments in the market for consumer debt may have spillovers into other areas of the financial services industry.
description: L’auteur met en évidence un lien entre les sphères réelle et financière de l’économie. Il constate l’existence d’une relation négative entre les flux de placement des particuliers dans les fonds d’actions au Canada et les variations contemporaines et passées d’une composante du taux préférentiel et du taux hypothécaire à cinq ans qui n’est pas corrélée avec les taux des titres d’État. L’effet subsiste lorsqu’on tient compte de l’incidence d’autres déterminants de ces flux et est plus prononcé dans le cas des grands fonds bien établis. Les résultats indiquent que les flux de placement des ménages dans les fonds d’actions canadiennes mettent du temps à réagir aux modifications des taux d’intérêt et que l’évolution du marché du crédit à la consommation peut se répercuter dans d’autres branches du secteur des services financiers.

description: This paper examines the impact of bank consolidation on mortgage rates in order to evaluate the extent to which mortgage markets are competitive. Mortgage markets are decentralized and so rates are determined through a search and negotiation process. The primary effect of a merger therefore is to reduce the number of partners available with whom to negotiate, although it can also change the characteristics of the product, and impact the search effort of consumers. Using a Canadian merger as a case study, we find that, overall, consolidation had little effect on rates suggesting that, on average, the mortgage market is fairly competitive. However, a decomposition of the aggregate treatment effect reveals important heterogeneity in the impact of the merger. We find that consumers gathering multiple quotes are affected by the merger, while those who do not search are not. These results suggest that market power originates in large part from the presence of asymmetric search costs.
description: Les auteurs examinent l’effet des regroupements bancaires sur les taux d’intérêt hypothécaires afin d’évaluer le degré de compétitivité des marchés hypothécaires. Comme ces marchés sont décentralisés, les taux y sont déterminés au moyen d’un processus de recherche et de négociation. Dès lors, la fusion de deux institutions a pour principale conséquence de réduire le nombre de partenaires potentiels avec qui négocier, bien qu’elle puisse aussi s’accompagner de changements dans les caractéristiques du produit et se répercuter sur les efforts de recherche des consommateurs. Prenant pour étude de cas la fusion de deux banques canadiennes, les auteurs notent que celle-ci a eu dans l’ensemble peu d’incidence sur les taux pratiqués, ce qui donne à penser que le marché hypothécaire est relativement compétitif. Toutefois, la décomposition de l’effet moyen observé révèle que la fusion a eu une incidence très variable selon les ménages. Les consommateurs qui font des démarches auprès de plusieurs institutions ont été touchés par la fusion, mais pas les autres. Ces résultats indiquent que le pouvoir de marché tient en grande partie à la présence de coûts de recherche asymétriques.

description: Gravitational-wave memory, a strong-field effect of general relativity, manifests itself as a permanent displacement in spacetime. We develop a Bayesian framework to detect gravitational-wave memory with the Advanced LIGO/Virgo detector network. We apply this algorithm on the ten binary black hole mergers in LIGO/Virgo's first transient gravitational-wave catalog. We find no evidence of memory, which is consistent with expectations. In order to estimate when memory will be detected, we use the best current population estimates to construct a realistic sample of binary black hole observations for LIGO/Virgo at design sensitivity. We show that an ensemble of $\mathcal{O}(2000)$ binary black hole observations can be used to find definitive evidence for gravitational-wave memory. We conclude that memory is likely to be detected in the early A+/Virgo+ era.

description: This paper analyzes co-movements and discusses possible market integration between aggregate food and stock markets in the period of 1990 to 2012. Correlations, price return distributions, cointegration, and Granger-causalities are tested in subsamples on monthly FAO Food Price Index and MSCI World Stock Market Index data to better assess why and whether linkages between food and financial markets have increased. Empirical results suggest that while there is only weak indication of greater co-movements concurrent with structural changes such as changed agricultural policies, new demand due to growth in emerging markets and energy mandates, and the financialization of food markets since the early 2000s, they did start to increase in particular substantially during the financial stress of the Lehman crisis and the Great Recession. It is concluded that while structural changes may have amplified price linkages across markets, results do not suggest that they are the key factors for greater price co-movements. Instead, it is discussed that the effects of the late-2000s recession as a time of great economic weakness and uncertainty may have changed concurrently the behavior of both food and financial market participants, such that different market prices exhibit increased co-movements.
Adjustable point supported glass floor in the renewed building of the National Museum in Prague

description: The building of the National Museum in Prague is a part of the historical heritage of the Czech Republic. Very huge reconstruction and maintenance of whole building was ongoing during the last decade. Special emphasis was devoted to every detail of the interior as well as the facade elements to keep the historical value of the building adding modern architectural elements like transport glass flooring and balustrades. This paper deals with the project of the glass flooring in total area about 200m2 placed directly in the main tower of the building as a representative place with nice view to a historical parts of the city. The tower is a part of the main Pantheon with historical coloured glass elements visible from the inside of the building, therefore, glass flooring was the only possible solution to open this area for people by keeping the daylight from the top of the Pantheon.

description: This study investigates risk and time preferences of small-scale cattle farmers in West Africa and examines how demographic and socio-economic characteristics are related to these preferences. Using a maximum likelihood approach we jointly estimate risk and time preferences. Our findings show that, overall the West African cattle farmer shows poor performance in using probability information and is generally risk averse. The average cattle farmers’ time preferences indicate a higher degree of patience than expected. We also find that income, education, and religion are highly correlated with risk and time preferences.
Growth, microstructure, and failure of crazes in glassy polymers

description: We report on an extensive study of craze formation in glassy polymers. Molecular dynamics simulations of a coarse-grained bead-spring model were employed to investigate the molecular level processes during craze nucleation, widening, and breakdown for a wide range of temperature, polymer chain length $N$, entanglement length $N_e$ and strength of adhesive interactions between polymer chains. Craze widening proceeds via a fibril-drawing process at constant drawing stress. The extension ratio is determined by the entanglement length, and the characteristic length of stretched chain segments in the polymer craze is $N_e/3$. In the craze, tension is mostly carried by the covalent backbone bonds, and the force distribution develops an exponential tail at large tensile forces. The failure mode of crazes changes from disentanglement to scission for $N/N_e\sim 10$, and breakdown through scission is governed by large stress fluctuations. The simulations also reveal inconsistencies with previous theoretical models of craze widening that were based on continuum level hydrodynamics.
Maxwell-dilaton dynamics

description: The dynamics of Maxwell-dilaton theory in Minkowski spacetime are studied using fully nonlinear, numerical evolutions. This model represents the flat-space sector of Einstein-Maxwell-Dilaton theory which has attracted interest recently because it is a well-posed alternative to general relativity, and it also represents the abelian sector of Yang-Mills-Dilaton. As such, understanding its dynamics may shed light on the dynamics of the respective larger systems. In particular, we study electric, magnetic, and dyonic monopoles as well as the flux tubes studied previously by Gibbons and Wells. Some scenarios produce large gradients that an increasing adaptive mesh refinement fails to resolve. This behavior is suggestive, although far from conclusive, that the growth leads to singularity formation. No sharp transition between singularity formation and either dispersion or stationarity is found, unlike other nonlinear systems that have demonstrated behavior similar to black hole critical behavior at such transitions.

Adjustable Mould for the Casting of Glass Voussoirs for the Construction of Fully Transparent Shell Structures
Creators: name: Van Der Weijst, Felix

name: Bilow, Marcel
Publisher: name: Challenging Glass Conference Proceedings
Year: 2020

description: Compared to flat sheets of float glass, cast glass components have a thicker geometry and thus a high buckling resistance. This buckling resistance in combination with the high compressive strength of glass make cast glass components suitable for the construction of fully transparent shell structures that are mainly subjected to compressive stresses. Shell structures often have the shape of surfaces with varying Gaussian curvature. When constructing such a shell structure out of cast glass components, components of varying geometries are needed. An adjustable mould was developed that can be used for the casting of glass components (i.e. voussoirs) of varying geometries. The possible voussoir geometries that can be cast in the adjustable mould are limited to voussoirs with planar, convex, polygonal intrados and extrados. These voussoirs can be used to construct fully transparent shell structures. The voussoirs are dry-assembled with a rubber interlayer in between. Tongue and groove shaped interfaces ensure an interlocking connection. By tessellating a shell structure, the shell structure is divided into a discrete number of voussoirs that can be cast in the adjustable mould. Several aspects have to be taken into account when optimizing the tessellation pattern including planarity, interior angle size, face size and alignment to the flow of forces. A design was made of a shell structure that covers the courtyard of the Armamentarium in Delft. This shell structure served as a case study used to demonstrate the tessellating process and the use of the mould developed during this research.

description: An old play has recently been extended across the border from Germany into the Netherlands, an area previously thought to be barren of reservoir sandstones. The combination of core evaluation with observations from modern analogues help to refine the depositional geometries and architecture of the basal Upper Rotliegend play. The study area is located in the Southern Permian Basin, comprising wadi and dune sandstones and a central desert lake. The dimensions of the desert sand facies belts in North Oman are similar to those in the Southern Permian Basin and, similar to the base Upper Rotliegend situation, a relief characterises the hinterland of the desert system while a large desert lake is missing. For this setting lake Eyre (Australia) is an example. Here, the mountain ranges from which the fluvial feeder systems originate are more than 500 km away and the landscape surrounding the lake is flat. Flood events in the Rotliegend are usually thought to be unconfined sheet-type floods, leaving behind sheet-like sediments. However, the Lower Slochteren Member was characterised by a relief, which confined rivers and thereby channel deposits could develop. Fluvial events in desert systems from Oman and near Lake Eyre rather resemble braided streams during waning flow stages, where a water sheet is only present during maximum discharge. This is consistent with fluvial deposits in the study area, which are characterised by a depositional sequence reflecting a change from high density currents to low density currents to standing water deposits. Indeed, desert river floods are typically short-lived events with strongly changing sediment/water ratios and current velocities leaving behind a characteristic depositional “flashflood sequence”, analogue to the classic Bouma sequence. It is mostly assumed that fluvial sands entering the Silverpit lake were deposited by a sediment plume. After drying out, the sediment is assumed to be reworked by wind, leaving few traces of the fluvial activity. In addition to overprinted sediments, coarsening-upward subaqueous bar type deposits are locally common in the study area. Also in Lake Eyre, subaqueous delta facies and channel systems representing pro-delta features occur, which remain visible during periods of drought. Evaporitic cements and a high groundwater table may help to preserve the pro-delta deposits, which can be good quality reservoir sands. These improvements of the depositional model help to unravel the depositional settings of the basal Upper Rotliegend sandstones and allow for exploration of sweet spots in yet underexplored areas.

description: The Chandra Multi-wavelength Project (ChaMP) is a wide-area (~14 deg^2) survey of serendipitous Chandra X-ray sources, aiming to establish fair statistical samples covering a wide range of characteristics (such as absorbed AGNs, high z clusters of galaxies) at flux levels (fX ~ 10^-15 - 10^-14 erg sec-1 cm-2) intermediate between the Chandra Deep surveys and previous missions. We present the first ChaMP catalog, which consists of 991 near on-axis, bright X-ray sources obtained from the initial sample of 62 observations. The data have been uniformly reduced and analyzed with techniques specifically developed for the ChaMP and then validated by visual examination. To assess source reliability and positional uncertainty, we perform a series of simulations and also use Chandra data to complement the simulation study. The false source detection rate is found to be as good as or better than expected for a given limiting threshold. On the other hand, the chance of missing a real source is rather complex, depending on the source counts, off-axis distance (or PSF), and background rate. The positional error (95% confidence level) is usually < 1" for a bright source, regardless of its off-axis distance while it can be as large as 4" for a weak source (~20 counts) at a large off-axis distance (Doff-axis > 8'). We have also developed new methods to find spatially extended or temporary variable sources and those sources are listed in the catalog.

title: The Effects of Oil Price Uncertainty on the Macroeconomy
Creators: name: Jo, Soojin
Publisher: name: Bank of Canada
Year: 2012

description: This paper investigates the effect of oil price uncertainty on real economic activity using a quarterly VAR with stochastic volatility in mean. Stochastic volatility allows oil price uncertainty to vary separately from changes in the level of oil prices, and thus the impact of oil price uncertainty can be examined in a more flexible yet tractable way. In addition, this paper substantially improves on the recovery of a historical uncertainty series by incorporating an additional uncertainty indicator, i.e., a realized volatility series from daily oil price data, into the estimation process. The estimation results show that an oil price uncertainty shock alone has negative effects on world industrial production.
description: L’auteure analyse les effets de l’incertitude des cours du pétrole sur l’activité économique réelle à l’aide d’un modèle VAR trimestriel dont les équations de moyenne incluent un terme de volatilité stochastique. La volatilité stochastique permet à l’incertitude entourant les prix du pétrole de varier indépendamment de leur niveau; l’incidence de cette incertitude peut ainsi être étudiée dans un cadre plus flexible qui reste maniable. En outre, l’intégration au processus d’estimation d’un indicateur additionnel de l’incertitude, à savoir une série de volatilités réalisées calculées à partir des cours quotidiens de l’or noir, constitue un réel progrès par rapport à l’extraction d’une série temporelle relative à l’incertitude. Les résultats de l’estimation montrent qu’une hausse inattendue de l’incertitude des prix du pétrole a en soi des effets défavorables sur la production industrielle mondiale.

description: Agri-environmental measures are often not as accepted among farmers as expected. The present study investigates whether changes in income risks and the individual risk attitudes of farmers may constitute an explanatory approach for the low acceptance of the measures. For this purpose, a normative model is developed that calculates the premia claimed by the farmers for adopting environmental measures under the consideration of income risks and different risk attitudes. We apply this model to environmental measures aiming at an increase of the faunistic diversity of species and show that changes in income risks and the decision makers’ risk attitudes can significantly influence farmers’ minimum compensation claims for the participation in agri-environmental measures.

description: We have used N-body simulations to develop two independent methods to quantify redshift distortions known as the Bull's Eye effect (large scale infall plus small scale virial motion). This effect depends upon the mass density, $Ω_0$, so measuring it can in principle give an estimate of this important cosmological parameter. We are able to measure the effect and distinguish between its strength for high and low values of $Ω_0$. Unlike other techniques which utilize redshift distortions, one of our methods is relatively insensitive to bias. In one approach, we use path lengths between contour crossings of the density field. The other is based upon percolation. We have found both methods to be successful in quantifying the effect and distinguishing between values of $Ω_0$. However, only the path lengths method exhibits low sensitivity to bias.

description: The paper analyses the continuity of the demarcation process of Czech regions for the state support. This support aims to reduce negative disparities among the regions. The process of demarcation of the region includes criteria as an unemployment rate, number of applicants per one job vacancy, income tax rate, number of private entrepreneurs and purchasing power. These criteria and weights of these criteria have been changed during the last 20 years. The main aim of this paper is the analysis of the criteria set and the criteria weights modification during the years 1991 – 2010 and the examination of the modification of values of the criteria weights using two different methods - Analytic Hierarchy Process and Analytic Network Process. These methods are used for synthesis of the criteria weights, which shows the continuity of the region demarcation process during its modification in time.
title: Estimating the Policy Rule from Money Market Rates when Target Rate Changes Are Lumpy
Creators: name: Fontaine, Jean-Sébastien
Publisher: name: Bank of Canada
Year: 2012

description: Most central banks effect changes to their target or policy rate in discrete increments (e.g., multiples of 0.25%) following public announcements on scheduled dates. Still, for most applications, researchers rely on the assumption that the policy rate changes linearly with economic conditions and they do not distinguish between dates with and without scheduled announcements. This assumption is not innocuous when estimating the policy rule based on daily frequency. For the 1994-2011 period, and using an otherwise standard term structure model, I find that accounting for discrete changes leads to economically different estimates. Only the model based on discrete changes depicts a picture that is consistent with existing evidence on the monetary policy rule and risk premium. I study the information content of key policy announcements in the period from the end of 2008, where the policy rate reached a lower bound in the US, until the end of 2011.
description: Le taux cible ou directeur de la majorité des banques centrales fait l’objet de modifications discrètes plutôt que continues (par multiples de 25 points de base par exemple), annoncées publiquement à des dates préétablies. La plupart du temps, toutefois, les chercheurs partent de l’hypothèse que le taux directeur varie linéairement avec les conditions économiques, sans établir de distinction entre les dates d’annonce prévues au calendrier et les autres jours. Cette hypothèse n’est pas sans conséquence lorsque la règle de politique monétaire est estimée à partir de données quotidiennes. Pour la période 1994-2011, et dans le cadre d’un modèle de structure par terme par ailleurs standard, l’auteur montre que la prise en compte du caractère discret des changements du taux directeur aboutit à des estimations différentes du point de vue économique. Le modèle intégrant des changements discrets est le seul dont les résultats cadrent avec ceux existant quant à la règle de politique monétaire et à la prime de risque. L’auteur étudie aussi le contenu informatif des principales annonces effectuées par la Réserve fédérale entre la fin de 2008, où le taux directeur est tombé à un plancher aux États-Unis, et la fin de 2011.

description: We analyzed 1441 Chandra X-ray point sources in 32 nearby galaxies. The total point-source X-ray luminosity L_XP is well correlated with B, K, and FIR+UV luminosities of spiral host galaxies, and with the B and K luminosities for ellipticals. This suggests an intimate connection between L_XP and both the old and young stellar populations, for which K and FIR+UV luminosities are proxies for the galaxy mass M and star-formation rate SFR. We derive proportionality constants 1.3E29 erg/s/Msol and 0.7E39 erg/s/(Msol/yr), which can be used to estimate the old and young components from M and SFR, respectively. The cumulative X-ray luminosity functions for the point sources have quite different slopes for the spirals (gamma ~= 0.5-0.8) and ellipticals (gamma ~= 1.4), implying *the most luminous point sources dominate L_XP* for the spirals. Most of the point sources have X-ray colors that are consistent with either LMXBs or Ultraluminous X-ray sources (ULXs a.k.a. IXOs) and we rule out classical HMXBs (e.g. neutron-star X-ray pulsars) as contributing much to L_XP. Thus, for spirals, the ULXs dominate L_XP. We estimate that >~20% of all ULXs found in spirals originate from the older (pop II) stellar populations, indicating that many of the ULXs that have been found in spiral galaxies are in fact pop II ULXs, like those in elliptical galaxies. The linear dependence of L_XP on the SFR argues for either a steepening in the X-ray luminosity function of the young (pop I) X-ray source population at L_X >~10^(38.5-39) erg/s, or a decreasing efficiency for producing all types of young X-ray point sources as the galaxy SFR increases.

description: High-resolution observations of high-redshift ($z>4$) radio quasars offer a unique insight into jet kinematics at early cosmological epochs, as well as constraints on cosmological model parameters. Due to the general weakness of extremely distant objects and the apparently slow structural changes caused by cosmological time dilation, only a couple of high-redshift quasars have been studied with parsec-scale resolutions, and with limited number of observing epochs. Here we report on very long baseline interferometry (VLBI) observations of a high-redshift blazar J1430+4204 ($z=4.72$) in the 8 GHz frequency band at five different epochs spanning 22 years. The source shows a compact core--jet structure with two jet components being identified within 3 milli-arcsecond (mas) scale. The long time span and multiple-epoch data allow for the kinematic studies of the jet components. That results in a jet proper motion of $μ{\rm (J1)}$ = 0.017$\pm$0.002~mas\,yr$^{-1}$ and $μ({\rm J2})$=0.156$\pm$0.015~mas\,yr$^{-1}$, respectively. For the fastest-moving outer jet component J2, the corresponding apparent transverse speed is $19.5 \pm 1.9 \,c$. The inferred bulk jet Lorentz factor $Γ= 14.6 \pm 3.8$ and viewing angle $θ= 2.2^{\circ} \pm 1.6^{\circ}$ indicate highly relativistic beaming. The Lorentz factor and apparent proper motion are the highest measured to date among the $z>4$ jetted radio sources, while the jet kinematics is still consistent with the cosmological interpretation of quasar redshifts.

description: Understanding the dynamics of the magnetic skyrmion, a particle-like topologically stable spin texture, and its response dynamics to external fields are indis-pensable for the applications in spintronic devices. In this letter, the Lorentz transmis-sion electron microscopy (LTEM) was used to investigate the spin chirality of the mag-netic skyrmion bubbles (SKBs) in the centrosymmetric magnet MnNiGa at room tem-perature. The reversal of SKBs excited by the in-plane magnetic field has been revealed. Moreover, the collective behavior of interacting spin chirality can be manipulated by reversing the directions of the magnetic fields on a wedge-shaped thin plate. The dy-namic behavior of the bubbles at different position of the thin plate has been explored with the micromagnetic simulation, indicating a non-uniform and nontrivial dynamic magnetization on the surfaces and center of the thin plate during the spin chirality re-versal. The results suggest that the controllable symmetry breaking of the SKBs arising from thickness variation provides an ability to manipulate the collective behavior of the spin chirality with small external fields, leading to a promising application in nonvola-tile spintronic devices for magnetic skyrmions.

description: Photoelectrochemical (PEC) water splitting is one of the most sustainable approaches for converting solar energy into hydrogen fuel. Affordable and robust photoelectrodes are crucial for the commercialization of PEC technologies. Recently, transition metal-based co-catalysts, especially Ni- and Fe-based catalysts, have attracted much interest owing to their exceptional OER characteristics. Given this, we here proposed the decoration of a Fe-Ni-based cocatalyst on the surface of the TiO2 photoanode for PEC water splitting. The TiO2 photoanode was hydrothermally synthesized and then decorated by Fe-Ni hydroxide catalyst using photo-assisted electrodeposition. The optimized TiO2/FeNiOOH photoanode exhibited the maximum photocurrent density value of 1.36 mA cm−2, which is almost twice the value obtained for bare TiO2, at 1.23 V vs RHE under the AM 1.5 G illumination. Due to the enhanced light absorption in the UV region, the optimized photoanode exhibited remarkable IPCE and photoconversion efficiency of 87.8% and 0.93%, respectively. Furthermore, excellent faradaic efficiencies of ∼90% for H2 and ∼70% for O2 generations were obtained. Predominantly, the enhancement in the photocurrent potentials was explained in detail. Our study shows the roles and benefits of using bimetallic catalysts with TiO2 photoanodes for sustainable water-splitting applications.

description: This paper contains an analysis of the Russian foreign trade in agricultural products and foodstuffs from the two points of view: international competitiveness and country’s trade balance. The aim of the analysis is to distinguish from the total agricultural export flows specific groups of products according to their comparative advantage (or disadvantage) and trade balance, to trace changes that have occurred in this groups over the period and to explain why these changes have taken place. The analysis is based on the combination of two indices i.e. Revealed Symmetric Comparative Advantage, and Trade Balance Index that were used to represent an analytical tool named “products mapping”. During the study, from the total export flows we distinguished a group of products (Group A) that includes 5% of the exported goods, but accounts for about 50% of the value of total agricultural exports. Items in this group have a comparative advantage and positive trade balance. The greatest weight in the group A has wheat. There was also identified the group D where 80% of items account for only about 30% of total exports, but 95-99% of the total imports. These items have comparative disadvantage and negative trade balance. But there was a reduction in the value of group D, while the group A has been steadily growing. These trends can be considered as a strengthening of the comparative advantages of Russian agricultural export.

description: Due to the increasing priority orientated towards more integrated policy concepts, such as rural development policy, there is a growing need to address the concept of multifunctionality for policy assessment. In particular, the dependence of the various tasks and services provided by agriculture on the territorial contexts is a key issue in valuing adequately the potential of agriculture and forestry in diverse types of rural regions. These questions were therefore the main aims of EU FP6 research project TOP-MARD 2 which tried to develop the concept of multifunctionality as a rural development policy instrument that is sensitive to economic, social, cultural, environmental and geographical context. The project was designed to analyze how the various functions of the agricultural sector in any given territory affect the sustainable economic development and the quality of life of that territory, and how different policies affect these relationships. In a sample of 11 EU countries specifi c study areas were selected to explore the diversity of multiple functions, co-production, and impacts on rural development across Europe. One of the main objectives and outputs of the research project was to improve our knowledge about the relationships affecting multifunctional tasks. A core project deliverable was to characterize these driving forces and interrelations in a policy model (called POMMARD) which would allow the simulation of the dynamic economic, social and environmental impacts of different future policy scenarios in different rural contexts. The paper presents an overview of the objectives and structures of the project, including a comparison of the case study areas and an overview of the POMMARD model. As the provision of tasks going beyond agriculture is particularly expressed in contexts of less-favoured and mountainous areas, a comparative analysis of territorial impacts of multifunctional agriculture in two mountain regions will be presented here: the Pinzgau-Pongau region (Austria), and the Gorenjska region (Slovenia). A set of policy and market scenarios (fi ve policy scenarios) that were tested across all the study areas are summarized for these two regions by analysing the model results and focusing on major conclusions of the project.

description: This paper studies a dynamic version of the Holmstrom-Tirole model of intermediated finance. I show that competitive equilibria are not constrained efficient when the economy experiences a financial crisis. A pecuniary externality entails that banks’ desire to accumulate capital over time aggravates the scarcity of informed capital during the financial crisis. I show that a constrained social planner finds it beneficial to introduce a permanent wedge between the deposit rate and the economy’s marginal rate of transformation. The wedge improves borrowers’ access to finance during a financial crisis by strengthening banks’ incentives to provide intermediation services. I propose a simple implementation of the constrained-efficient allocation that limits bank size.
description: Dans cette étude, l’auteur utilise une version dynamique du modèle d’intermédiation financière de Holmstrom et Tirole. Il montre que les équilibres concurrentiels ne sont pas soumis à une contrainte d’efficience quand l’économie subit une crise financière. Sous l’effet d’une externalité pécuniaire, le désir des banques d’accumuler des fonds propres au fil du temps aggrave, lors de la crise financière, la rareté des capitaux en provenance d’investisseurs disposant d’un avantage informationnel. L’auteur fait ressortir que, pour un planificateur central soumis à une contrainte, il est avantageux d’introduire un écart permanent entre le taux de rémunération des dépôts et le taux marginal de transformation de l’économie. Cette différence améliore l’accès des emprunteurs au crédit en période de crise financière, car elle rend l’offre de services d’intermédiation plus attrayante pour les banques. L’auteur propose une simple application d’une allocation sous contrainte d’efficience qui limite la taille des banques.
The Biblical sources of Modern Hebrew syntax

description: The paper assesses the influence on Modern Hebrew of the two previous spoken stages of Hebrew: Biblical Hebrew and Rabbinic Hebrew in its early, Mishnaic, phase. Contra the received view in the current literature, I argue that Modern Hebrew has in many respects readopted the syntax of Biblical Hebrew, the earlier of the two ancient stages, rather than being a development of the subsequent Rabbinic stage. The paper discusses particular constructions whose Biblical syntax had historically been replaced by Rabbinic syntax, yet were reinstated in Modern Hebrew. These include clausal constructions such as conditional and unconditional clauses, clausal complements of aspectual and modal auxiliaries, and gerundive clauses. The Rabbinic component in the syntax of Modern Hebrew seems to be limited to values and exponents drawn from Rabbinic Hebrew for the functional categories originating in Biblical Hebrew or in languages with which Hebrew was in contact during its history.
