description: This paper investigates the impact of market structure on the joint determination of exchange rate pass-through and currency of invoicing in international trade. A novel feature of the study is the focus on market share of firms on both sides of the market—that is, exporting firms and importing firms. A model of monopolistic competition with heterogeneous firms has the following set of predictions: a) exchange rate pass-through should be non-monotonic and U-shaped in the market share of exporting firms, but monotonically declining in the market share of importers; b) exchange rate pass-through should be lower, the higher is local currency invoicing of imports; and c) producer currency invoicing should be related non-monotonically and U-shaped to exporter market share, and monotonically declining in importing firms’ market share. We test these predictions using a new and large micro data set covering the universe of Canadian imports over a six-year period. The data strongly support all three predictions.
description: Nous analysons l’effet de la structure de marché sur le choix du degré de transmission des variations du taux de change et la monnaie de facturation retenue dans les échanges internationaux. L’originalité de l’étude est l’intérêt porté aux deux côtés du marché, c’est-à-dire aux exportateurs et aux importateurs. Le modèle de concurrence monopolistique à entreprises hétérogènes utilisé aboutit à une série de prévisions : a) la relation entre la transmission des variations du taux de change et la part de marché des exportateurs devrait être non monotone et donner lieu à une courbe en U; en ce qui concerne la part de marché des importateurs, la relation décroît de façon monotone; b) la transmission des variations du taux de change devrait être faible lorsque les importations sont plus susceptibles d’être facturées dans la monnaie de l’importateur; c) la facturation dans la monnaie des producteurs devrait donner lieu à une relation non monotone avec la part de marché des exportateurs et à une courbe en U, ainsi qu’à une relation constamment décroissante avec la part de marché des importateurs. Ces prévisions sont vérifiées à l’aide d’un nouvel ensemble de microdonnées sur toutes les importations canadiennes effectuées en six ans. Les données confirment largement chacune des trois prévisions.

description: In this paper we study the Macroscopic Quantum Oscillation (MQO) effect in ferromagnetic single domain magnets with a magnetic field applied along the hard anistropy axis. The level splitting for the ground state, derived with the conventional instanton method, oscillates with the external field and is quenched at some field values. A formula for quantum tunneling at excited levels is also obtained. The existence of topological phase accounts for this kind of oscillation and the corresponding thermodynamical quantities exhibit similar interference effects which resembles to some extent the electron quantum phase interference induced by gauge potential in the Aharonov-Bohm effect and the $Θ$-vacuum in Yang-Mills field theory..

description: Although classifiers/quantifiers (CQs) expressions appear frequently in everyday communications or written documents, they are described neither in classical bilingual paper dictionaries , nor in machine-readable dictionaries. The paper describes a CQs dictionary, edited from the corpus we have annotated, and its usage in the framework of French-Japanese machine translation (MT). CQs treatment in MT often causes problems of lexical ambiguity, polylexical phrase recognition difficulties in analysis and doubtful output in transfer-generation, in particular for distant languages pairs like French and Japanese. Our basic treatment of CQs is to annotate the corpus by UNL-UWs (Universal Networking Language-Universal words) 1 , and then to produce a bilingual or multilingual dictionary of CQs, based on synonymy through identity of UWs.

title: Examining Full Collateral Coverage in Canada’s Large Value Transfer System
Creators: name: Embree, Lana

Publisher: name: Bank of Canada
Year: 2015

description: The Large Value Transfer System (LVTS) is Canada’s main electronic interbank funds transfer system that financial institutions use daily to transmit thousands of payments worth several billions of dollars. The LVTS is different than real-time gross settlement (RTGS) systems because, while each payment is final and irrevocable, settlement occurs on a multilateral net basis at the end of the day. Furthermore, LVTS payments are secured by a collateral pool that mutualizes losses across participants in the event of a default.

In this paper, we use the Bank of Finland Simulator to examine the implications of fully collateralizing LVTS payments, similar to an RTGS. An important caveat to consider, however, is that the simulations do not take into account the anticipated change in payment behaviour in response to a change in collateral requirements. In this regard, we include a queuing mechanism to at least reflect more efficient use of liquidity. The results indicate that collateral requirements vary by participant and some participants actually require less collateral in the simulation than what is required under the current LVTS design.
description: Le Système de transfert de paiements de grande valeur (STPGV) est le principal système interbancaire de virement électronique de fonds du Canada. Il est utilisé quotidiennement par les institutions financières pour transmettre des milliers de paiements dont la valeur s’élève à plusieurs milliards de dollars. Le STPGV diffère des systèmes à règlement brut en temps réel, car, bien que chaque paiement soit final et irrévocable, le règlement se fait à la fin de la journée par l’inscription des positions nettes multilatérales. De plus, les paiements effectués sont garantis par un portefeuille de sûretés, ce qui permet de répartir les pertes entre les participants en cas de défaillance.

À l’aide du simulateur de la Banque de Finlande, nous étudions les effets qu’entraînerait pour les participants au STPGV le nantissement de la totalité des paiements, une exigence similaire à celle qu’on trouve dans le cas des systèmes à règlement brut en temps réel. Il convient toutefois de souligner que les simulations ne tiennent pas compte du changement anticipé des habitudes de paiement qu’induirait une modification des exigences en matière de sûretés. C’est pourquoi nous intégrons un mécanisme de mise en attente, qui permet de simuler partiellement une utilisation plus efficiente des liquidités. Les résultats montrent que les exigences varient selon les participants et que, pour certains d’entre eux, le montant qui leur est imposé par le simulateur est, en fait, inférieur à celui qu’ils sont tenus d’acquitter dans le cadre du STPGV tel qu’il est conçu actuellement.
Numerical Study of Local and Global Persistence in Directed Percolation

description: The local persistence probability P_l(t) that a site never becomes active up to time t, and the global persistence probability P_g(t) that the deviation of the global density from its mean value rho(t)- does not change its sign up to time t are studied in a one-dimensional directed percolation process by Monte Carlo simulations. At criticality, starting from random initial conditions, both P_l(t) and P_g(t) decay algebraically with exponents theta_l ~ theta_g ~ 1.50(2), which is in contrast to previously known cases where theta_g < theta_l. The exponents are found to be independent of the initial density and the microscopic details of the dynamics, suggesting that theta_l and theta_g are universal exponents. It is shown that in the special case of directed-bond percolation, P_l(t) can be related to a certain return probability of a directed percolation process with an active source (wet wall).

description: We consider the effect of classical phase fluctuations on the quasiparticle spectra of underdoped high-$T_c$ cuprate superconductors in the pseudogap regime above $T_c$. We show that photoemission and tunneling spectroscopy data are well accounted for by a simple model in which mean field d-wave quasiparticles are semiclasically coupled to supercurrents induced by fluctuating unbound vortex-antivortex pairs. We argue that the data imply that transverse phase fluctuations are important at temperatures above $T_c$, while longitudinal fluctuations are unimportant at all temperatures.

Corporeal language: the material embodiment of linguistic liminality
Creators: name: Saha, Asmita
Publisher: name: No Publisher Supplied
Year: 2021

description: This thesis explores how language and materiality encounter each other, shaping the world and how we conceive of it. Language has historically been developed for colonial and imperial purposes, so it inherently excludes people of color, women and queer people as meaning-making subjects. Language in its normative capacity, is also not equipped to reify the complex and dynamic material and social realities of these subjects. However, at the hands of these subjectivities, language as a fundamental mode of production of knowledge, is challenged; its codes and conventions are rewritten, and its semantic and linguistic rationale is disrupted as a strategic and intentional maneuver at dismantling hegemonic power structures. The exploration of moments of rupture, dissonance and disconnect where the material and the linguistic does not coincide, allow for relational, partial, contradictory and discontinuous affectivity and act as sites of generation that produces agential identity formation for these subjectivities. This unsettles the coherent, continuous and unitary conditions of the Western Liberal Human/Self, giving rise to the possibilities of alternative modes of production of knowledge and epistemologies, that work to create new non-identitarian, non-unitary reconfigurations of be-ing human. The project sets up a theoretical framework in the first chapter that guides the critical analysis of the two primary texts chosen for the research. The second chapter focuses on Ocean Vuong’s novel On Earth We Are Briefly Gorgeous, exploring the untranslatability between physical embodiment and linguistic representation. The third chapter is based on Arundhuti Roy’s novel The Ministry of Utmost Happiness, analyzing how the queering of literary language can render non-heteronormative bodies visible and portray the vibrant performance of their gender expression. Both of these works signify transformative sites of meaning-making, where newer ways of conceiving, configuring and embodying otherized subjectivities can be discovered.

Optical properties of amorphous carbon dust around C-stars: new constraints from 2MASS and Gaia observations

description: In this work the optical properties of amorphous carbon (amC) dust condensed around carbon(C)-stars are constrained by comparing the observations for the Large Magellanic Cloud C-stars from the Two Micron All Sky Survey (2MASS) and from the Gaia data release 2 (DR2) with the synthetic photometry obtained by computing dust growth and radiative transfer in their circumstellar envelopes. The set of optical constants of amC dust considered have been pre-selected according to their ability to reproduce the infrared colour-colour diagrams in the Small Magellanic Cloud. Only two combinations of the optical data set and grain size are able to reproduce the infrared photometry and the Gaia observations simultaneously. The analysis presented provides information about the properties of amC dust grains that might be characterized by a diamond-like structure, rather than a graphite-like one, at least around the most dust-enshrouded C-stars, or be composed of "small" grains of size less than 0.04 $μ$m. The selected data sets will be adopted to compute grids of spectra as a function of the stellar parameters that will be employed to estimate the dust return and mass-loss rates of C-stars by fitting their spectral energy distribution, and to study the resolved stellar populations of nearby objects.

description: Simulators are a primary tool in computer architecture research but are extremely computationally intensive. Simulating modern architectures with increased core counts and recent workloads can be challenging, even on modern hardware. This paper demonstrates that simulating some GPGPU workloads in a single-threaded state-of-the-art simulator such as Accel-sim can take more than five days. In this paper we present a simple approach to parallelize this simulator with minimal code changes by using OpenMP. Moreover, our parallelization technique is deterministic, so the simulator provides the same results for single-threaded and multi-threaded simulations. Compared to previous works, we achieve a higher speed-up, and, more importantly, the parallel simulation does not incur any inaccuracies. When we run the simulator with 16 threads, we achieve an average speed-up of 5.8x and reach 14x in some workloads. This allows researchers to simulate applications that take five days in less than 12 hours. By speeding up simulations, researchers can model larger systems, simulate bigger workloads, add more detail to the model, increase the efficiency of the hardware platform where the simulator is run, and obtain results sooner.

description: We report the first audio frequency dielectric constant measurements of CO and N_2 in their solid phases. We have observed several new features, including (1) strong hysteresis effects above an onset temperature $T_{h} \simeq 42 K$ in the β-phase of pure N_2, (2) absence of the expected short range antiferroelectric dipolar ordering in CO down to 4.2 K, and (3) anomalous temperature dependence of the dielectric constant in the α-phases of both CO and N_2. Quantum mechanical treatment of the molecular rotation explains some of the observed anomalies in the α-phase, but the strong hysteresis indicates that pure geometrical frustration plays a significant role in the β-phase.

title: Risk Sharing in the Presence of a Public Good
Creators: name: Schroth, Josef
Publisher: name: Bank of Canada
Year: 2015

description: This paper studies an economy where agents can spend resources on consuming a private good and on funding a public good. There is asymmetric information regarding agents’ relative preference for private versus public good consumption. I show how private good consumption should be coordinated across agents within each period to ensure efficient contributions to fund the public good. If agents contributed similar amounts in the past, then coordination takes the form of positively correlated contributions in the current period. If an agent contributed more in the past, then coordination prescribes state-contingent socially wasteful private good consumption in the current period for that agent.
description: Dans cette étude, l’auteur examine une économie où les agents peuvent dépenser des ressources pour consommer un bien privé et financer un bien public. L’information au sujet de la préférence relative des agents à l’égard de la consommation de biens privés ou de biens publics est asymétrique. L’auteur montre comment, pour assurer l’efficience des contributions au financement du bien public, la consommation des biens privés doit être coordonnée entre les agents à l’intérieur de chaque période. Si les agents ont contribué des sommes similaires au bien public dans le passé, la coordination prend la forme d’une corrélation positive entre les contributions des agents au cours de la période actuelle. Si un agent a fourni une contribution plus élevée par le passé, la coordination implique que, pendant la période actuelle, l’utilité sociale de ses dépenses de consommation privée sera subordonnée à l’état du monde.

description: Recent experiments on atomic-scale metallic contacts have shown that the quantization of the conductance appears clearly only after the average of the experimental results. Motivated by these results we have analyzed a simplified model system in which a narrow neck is randomly coupled to wide ideal leads, both in absence and presence of time reversal invariance. Based on Random Matrix Theory we study analytically the probability distribution for the conductance of such system. As the width of the leads increases the distribution for the conductance becomes sharply peaked close to an integer multiple of the quantum of conductance. Our results suggest a possible statistical origin of conductance quantization in atomic-scale metallic contacts.

description: We suggest that a spin-charge separating ansatz, leading to non-Abelian $SU(2) \otimes U_S(1)$ gauge symmetries in doped antiferromagnets, proposed earlier as a way of describing Kosterlitz-Thouless superconducting gaps at the nodes of the gap of d-wave (high-T_c) superconductors, may also lead to a pseudogap phase, characterised by the formation of (non-superconducting) pairing and the absence of phase coherence. The crucial assumption is again the presence of electrically charged Dirac fermionic excitations (holons) about the points of the (putative) fermi surface in the pertinent phase of the superconductor. We present arguments in support of the rôle of non-perturbative effects (instantons) on the onset of the pseudogap phase. As a means of probing such gauge interactions experimentally, we perform a study of the scaling of the thermal conductivity with an externally-applied magnetic field, in certain effective models involving gauge and/or four-fermion (contact) interactions.

description: We study the emergence of cooperative behaviors in reinforcement learning agents by introducing a challenging competitive multi-agent soccer environment with continuous simulated physics. We demonstrate that decentralized, population-based training with co-play can lead to a progression in agents' behaviors: from random, to simple ball chasing, and finally showing evidence of cooperation. Our study highlights several of the challenges encountered in large scale multi-agent training in continuous control. In particular, we demonstrate that the automatic optimization of simple shaping rewards, not themselves conducive to co-operative behavior, can lead to long-horizon team behavior. We further apply an evaluation scheme, grounded by game theoretic principals, that can assess agent performance in the absence of pre-defined evaluation tasks or human baselines.

description: Women have become better represented in business, academia, and government over time, yet a dearth of women at the highest levels of leadership remains. Sociologists have attributed the leaky progression of women through professional hierarchies to various cultural and psychological factors, such as self-segregation and bias. Here, we present a minimal mathematical model that reveals the relative role that bias and homophily (self-seeking) may play in the ascension of women through professional hierarchies. Unlike previous models, our novel model predicts that gender parity is not inevitable, and deliberate intervention may be required to achieve gender balance in several fields. To validate the model, we analyze a new database of gender fractionation over time for 16 professional hierarchies. We quantify the degree of homophily and bias in each professional hierarchy, and we propose specific interventions to achieve gender parity more quickly.
Effects of Mindfulness-Based Interventions on Fear of Childbirth and Pain intensity management during Labour: A Systematic Review and Meta-analysis
Creators: name: Mubarek Nuru Ahmed

Publisher: name: Zenodo
Year: 2024

description: ABSTRACT

Background: The efficacy of mindfulness-based interventions (MBIs) in addressing labour pain and fear of childbirth (FOC) stands as an important area of inquiry. This systematic review and meta-analysis seek to assess the impact of MBIs on labour pain and FOC through a comprehensive synthesis and analysis of current evidence.

Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a thorough literature search was conducted. Thirteen randomised controlled trials with a total of 924 mothers were selected for analysis. The primary outcomes assessed were labour pain intensity and fear of childbirth (FOC). These were measured using validated instruments such as Visual Analogue Scale and the Wijma Delivery Expectancy Questionnaire.

Results: The results demonstrated significant decreases in fear of childbirth (FOC), (SMD = -0.93, 95% CI: -1.42 to -0.44; P<0.00001). and labour pain intensity (SMD = -1.12, 95% CI: -1.66 to -0.58; P<0.00001) among intervention groups. However, notable heterogeneity, variances in outcome measurement timepoints and participant features, alongside probable risk of bias stemming from study design constraints, necessitate judicious interpretation of these findings. While promising, the current evidence warrants further high-quality research to substantiate the efficacy of mindfulness-based interventions for FOC and labour pain.

Conclusions: Despite the limitations, MBIs present a promising non-pharmacological approach for managing FOC and labour pain. Future research should aim to mitigate methodological flaws present in current studies while striving to confirm these promising results. Implementation of MBIs into maternity care could offer a holistic approach, improving maternal and newborn outcomes.

We find that stoichiometric CoP_3 differs from the corresponding arsenide and antimonide in that it is metallic. As such the band structure must be modified if high thermopowers are to be achieved. In analogy to the antimonides it is expected that this may be done by filling with La. Calculations for LaFe_4P_12 show that a gap can in fact be opened by La filling, but that the valence band is too light to yield reasonable p-type thermopowers at appropriate carrier densities; n-type La filled material may be more favorable.

We show that this is not universally true and that also the size of the depositsand the welfare criterion play an important role.

description: Geochemical data provide key information on the timing of accretion and on the prevailing physical conditions during core/mantle differentiation. However, their interpretation depends critically on the efficiency of metal/silicate chemical equilibration, which is poorly constrained. Fluid dynamics experiments suggest that, before its fragmentation, a volume of liquid metal falling into a magma ocean undergoes a change of topology from a compact volume of metal toward a collection of sheets and ligaments. We investigate here to what extent the vigorous stretching of the metal phase by the turbulent flow can increase the equilibration efficiency through what is known as stretching enhanced diffusion. We obtain scaling laws giving the equilibration times of sheets and ligaments as functions of a Péclet number based on the stretching rate. At large Péclet, stretching drastically decreases the equilibration time, which in this limit depends only weakly on the diffusivity. We also perform 2D numerical simulations of the evolution of a volume of metal falling into a magma ocean, from which we identify several equilibration regimes depending on the values of the Péclet (Pe), Reynolds (Re), and Bond (Bo) numbers. At large Pe, Re and Bo, the metal phase is vigorously stretched and convoluted in what we call a stirring regime. The equilibration time is found to be independent of viscosity and surface tension and depends weakly on diffusivity. Equilibration is controlled by an efficient thermochemical stretching enhanced diffusion mechanism developing from the mean flow and entraining the surrounding silicate phase.

description: A variety of asymptotically valid tests for orthogonality, serial correlation, predictive failure, and of coefficient restrictions are presented, and their rejection probabilities are assessed in linear structural models with lagged-dependent and (possibly) jointly dependent variables by Monte Carlo methods. For all test procedures the small-sample distribution under the null usually deviates substantially from the asymptotic distribution; this impedes their use in a reliable model selection strategy for econometric time-series analysis. Despite the harassing dependence of type I errors on factors generally unknown to the practitioner, inconsistencies originating from specification errors or from disregarded simultaneity may be detected by particular tests in particular situations. From this study some clues emerge on how to interpret (in)significant values of the various test statistics.
title: On the Welfare Cost of Rare Housing Disasters
Creators: name: Xu, Shaofeng
Publisher: name: Bank of Canada
Year: 2015

description: This paper examines the welfare cost of rare housing disasters characterized by large drops in house prices. I construct an overlapping generations general equilibrium model with recursive preferences and housing disaster shocks. The likelihood and magnitude of housing disasters are inferred from historic housing market experiences in the OECD. The model shows that despite the rarity of housing disasters, Canadian households would willingly give up 5 percent of their non-housing consumption each year to eliminate the housing disaster risk. The evaluation of this risk, however, varies considerably across age groups, with a welfare cost as high as 10 percent of annual non-housing consumption for the old, but near zero for the young. This asymmetry stems from the fact that, compared to the old, younger households suffer less from house price declines in disaster periods, due to smaller holdings of housing assets, and benefit from lower house prices in normal periods, due to the negative price effect of disaster risk.
description: L’étude chiffre la perte de bien-être causée par les fortes chutes de prix des logements (phénomène rare des catastrophes sur le marché du logement). L’étude s’appuie sur un modèle d’équilibre général à générations imbriquées avec préférences récursives et chocs créés par l’effondrement des prix des logements. La probabilité et l’ampleur de telles catastrophes sont calculées au moyen des prix observés sur le marché du logement dans les pays de l’OCDE. Les résultats montrent que les ménages canadiens sont prêts à sacrifier chaque année 5 % de leurs dépenses de consommation hors logement afin d’éviter la matérialisation d’un risque d’effondrement des prix. Ce risque est évalué très différemment selon le groupe d’âge, les ménages plus âgés estimant la perte résultante de bien-être à 10 % de leurs dépenses de consommation annuelles hors logement, alors que les jeunes ménages la jugent quasi nulle. Cette asymétrie s’explique par le fait que les jeunes ménages souffrent moins que leurs aînés des conséquences des chutes de prix des logements survenues pendant une catastrophe, car leur patrimoine immobilier est moins important, et qu’ils bénéficient du recul des prix des logements en temps normal, en raison de l’effet dépréciateur induit par le risque de catastrophe.

title: Managerial Compensation Duration and Stock Price Manipulation
Creators: name: Schroth, Josef
Publisher: name: Bank of Canada
Year: 2015

description: I build a model of optimal managerial compensation where managers each have a privately observed propensity to manipulate short-term stock prices. It is shown that this informational asymmetry reverses some of the conventional wisdom about the relationship between reliance on short-term pay and propensity to manipulate. The optimal compensation scheme features a negative relationship between pay duration and manager manipulation activity, reconciling theory with recent empirical findings (Gopalan et al., 2014). Further, the model predicts that managers who spend more resources manipulating short-term stock prices also put more effort into generating longterm firm value.
description: L’auteur construit un modèle de rémunération optimale des gestionnaires où chaque gérant se voit assigner une propension à manipuler les prix courants des actions de son entreprise et observe soi-même cette propension. L’étude montre que l’asymétrie d’information due à cette auto-observation entraîne des constats qui vont à l’encontre d’une partie des idées communément admises sur la relation entre la propension à manipuler et l’importance de la rémunération de court terme. Le régime de rémunération optimale présente une relation négative entre l’horizon de la rémunération et la propension à la manipulation des gérants, et concilie ainsi la théorie et les découvertes empiriques récentes (Gopalan et autres, 2014). Le modèle prévoit en outre que les gestionnaires qui dépensent plus de ressources à la manipulation des prix courants des actions consacrent aussi davantage d’efforts en vue d’augmenter la plus-value de leur entreprise sur le long terme.
Ab initio calculation of the potential energy surface for the dissociation of H_2 on the sulfur covered Pd(100) surface

description: The presence of sulfur atoms on the Pd(100) surface is known to hinder the dissociative adsorption of hydrogen. Using density-functional theory and the full-potential linear augmented plane-wave method, we investigate the potential energy surface (PES) of the dissociative adsorption of H_2 on the sulfur covered Pd(100) surface. The PES is changed significantly compared to the dissociation on the clean Pd(100) surface, in particular for hydrogen close to the S atoms. While the hydrogen dissociation at the clean Pd(100) surface is non-activated, for the (2x2) sulfur adlayer (coverage Theta_S= 0.25) the dissociation of H_2 is inhibited by energy barriers. Their heights strongly depend on the distance between the hydrogen and sulfur atoms leading to a highly corrugated PES. The largest barriers are in the vicinity of the sulfur atoms due to the strong repulsion between sulfur and hydrogen. Still the hydrogen dissociation on the (2x2) sulfur covered Pd(100) surface is exothermic. Thus the poisoning effect of sulfur adatoms for H_2 dissociation at low sulfur coverage (Theta_S <= 0.25) is mainly governed by the formation of energy barriers, not by blocking of the adsorption sites. For the c(2x2) sulfur adlayer (Theta_S= 0.5), the PES for hydrogen dissociation is purely repulsive. This is due to the fact that for all different possible adsorption geometries the hydrogen molecules come too close to the sulfur adatoms before the dissociation is completed.

description: The gigantic decrease of resistance by an applied magnetic field, which is often referred to as colossal magnetoresistance (CMR), has been an attracting phenomenon in strongly correlated electron systems. The discovery of CMR in manganese oxide compounds has developed the science of strong coupling among charge, orbital, and spin degrees of freedom. CMR is also attracting scientists from the viewpoint of possible applications to sensors, memories, and so on. However, no application using CMR effect has been achieved so far, partly because the CMR materials which satisfy all of the required conditions for the application, namely, high operating temperature, low operating magnetic field, and sharp resistive change, have not been discovered. Here we report a resistance change of more than two-orders of magnitude at a magnetic field lower than 2 T near 300 K in an A-site ordered NdBaMn_2_O_6_ crystal. When temperature and a magnetic field sweep from insulating (metallic) phase to metallic (insulating) phase, the insulating (metallic) conduction changes to the metallic (insulating) conduction within 1 K and 0.5 T, respectively. The CMR is ascribed to the melting of the charge ordering. The entropy change which is estimated from the B-T phase diagram is smaller than what is expected for the charge and orbital ordering. The suppression of the entropy change is attributable to the loss of the short range ferromagnetic fluctuation of Mn spin moments, which an important key of the high temperature and low magnetic field CMR effect.
