A Constitution for the Anthropocene Body Politic
Creators: name: Iovino, Serenella
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

The following article is a slightly revised version of Serenella Iovino’s Keynote Address at the 2021 European Conference for the Humanities, jointly organised in Lisbon (5-7 May) by the UNESCO Social and Human Sciences Programme, the International Council for Philosophy and Human Sciences (CIPSH), and the Portuguese Foundation for Science and Technology (FCT). The theme of the Conference Section inaugurated by this lecture was “The Humanities in the Twenty-First Century”. By acknowledging the official approval of the BRIDGES Project on education for sustainability as a partner of the UNESCO Management of Social Transformation Program, Iovino evaluated the role of the Environmental Humanities in the agenda of the so-called ‘New Humanities’, paying special attention to their relevance during the COVID-19 pandemic. In this framework, Venice emerged both as a symbol and as a very concrete object of care, proving to be “a thinking machine” for contemporary natural-cultural dynamics, as Salvatore Settis has defined it. The lecture ended with the invitation to turn the current crisis into a constitutive moment for the ‘Anthropocene body politic’, namely, the earthly collective of agents and of processes, both human and nonhuman, natural and technological.

title: Inflation Dynamics and the New Keynesian Phillips Curve: An Identification-Robust Econometric Analysis
Creators: name: Dufour, Jean-Marie
name: Khalaf, Lynda
name: Kichian, Maral
Publisher: name: Bank of Canada
Year: 2005

description: The authors use identification-robust methods to assess the empirical adequacy of a New Keynesian Phillips curve (NKPC) equation. They focus on Galí and Gertler's (1999) specification, for both U.S. and Canadian data. Two variants of the model are studied: one based on a rational-expectations assumption, and a modification to the latter that uses survey data on inflation expectations. The results based on these two specifications exhibit sharp differences concerning: (i) identification difficulties, (ii) backward-looking behaviour, and (iii) the frequency of price adjustment. Overall, the authors find that there is some support for the hybrid NKPC for the United States, whereas the model is not suited to Canada. Their findings underscore the need for employing identification-robust inference methods in the estimation of expectations-based dynamic macroeconomic relations.
description: Pour éprouver la validité empirique d'une équation fondée sur la nouvelle courbe de Phillips keynésienne, les auteurs adoptent des méthodes d'inférence qui permettent de surmonter le problème de l'identification. Ils appliquent la spécification proposée par Galí et Gertler (1999) à l'étude des données américaines et canadiennes. Deux variantes du modèle retiennent leur attention. La première repose sur l'hypothèse des anticipations rationnelles, et la deuxième est basée sur une version modifiée de celle-ci qui met à profit des mesures de l'inflation attendue tirées d'enquêtes. Les résultats obtenus à l'aide de ces deux variantes sont nettement différents en ce qui concerne : i) le problème de l'identification; ii) le comportement adaptatif; et iii) la fréquence de rajustement des prix. Les auteurs concluent que la nouvelle courbe de Phillips keynésienne hybride décrit assez bien la dynamique de l'inflation dans le cas des États-Unis mais pas dans celui du Canada. Leurs observations confirment l'utilité de méthodes d'inférence robustes sur le plan de l'identification pour l'estimation de relations macroéconomiques dynamiques faisant intervenir des anticipations.
General Introduction to Environmental Humanities in India
Creators: name: Beggiora, Stefano
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

The article offers a general overview of the ecological debate and Environmental Humanities in India. After an introduction on the legacy of Gandhian ecological thought and contemporary literature, the essay focuses on the most discussed themes of the Indian classical tradition, with particular references to sacred texts (Vedas, Puranas, the epics). The sum of this knowledge is placed on the recursive perspective of Indian time: as yugas change, new structures of social life arise, reformulating society and its environment in a more holistic and sustainable way. This would be possible without ever denying the responsibility we all have in maintaining that personal empathy towards the environment that is reflected in Indian classical texts.

description: We present a ground-based near-infrared K-band image and an HST/WFPC2 image of the brightest cluster galaxy in Abell 193 (IC 1695). This object was selected as the central cluster galaxy using X-ray information. Both images reveal a triple nucleus structure. Previously, this galaxy was thought to have only 2 nuclei. We present colours and magnitudes and a colour plot of the three nuclei. The nuclear structure and colours of the nuclei in this galaxy suggest that a merger may have taken place in its recent history.

The Meteorological Occult: Submergences in the Venetian Fog
Creators: name: Duncan, Ifor
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

Blinking away fog as it collects between eyelashes – this article begins with a night walk in Venice and a reflection on an embodied encounter with countless suspended water particles. Here I consider fog as a political materiality in an expanded cultural and meteorological context, where, rather than simply limiting visibility, fog acts as an unexpected lens onto slow forms of pollution. In doing so, I turn to the scientific term ‘occult deposition’ – the settling of unsensed pollutants carried by fogs, mists, clouds, dew, and frosts onto surfaces, vegetation, and skin – and adapt it to develop the concept of ‘occult meteorology’. By doing so, I work towards reorienting the cultural significance of the occult. With this reorientation, instead of limiting human sensing, or harbouring unknown and threatening supernatural presences, fog is the intensity of sensing, relationally mediating through eyes, mouths and skins. Here bodies are submerged in everyday and imperceptibly polluted environments even above the surface of water, while fog disorients vast infrastructural systems, from commercial flight to petrochemical logistics. Thinking alongside Esther Leslie and Craig Martin, this article brings earth sciences into encounter with literature and cinema to attend to fog as both metaphor and materiality in the context of environmental degradation.

description: Considering vital roles of trace copper ions for the health of humans, it is critical to sensitively detect it in foodstuffs. Herein, an ultrasensitive and cost–effective coumarin based fluorescent strategy with a “turn–off” signal was developed for specific detection of trace Cu2+ ions. Synthesis of 6,7-dihydroxy-3-(3-methylphenyl)coumarin (TMAC) probe was performed and characterized. The developed fluorescent probe presented excellent selectivity. The limit of detection of the sensor can reach as low as 5.13 nM in ACN/H2O (v/v=95/5) buffered by 5 μM HEPES buffer at pH = 7.0, and it is below the World Health Organization (WHO) guideline for drinking water (31.5 μM). The probable stoichiometry of TMAC–Cu2+ complex (1:1) was determined by Job's plot method and confirmed by FT–IR and ESI–MS. We further successfully applied TMAC for Cu2+ detection in water and various beverage samples with good recovery (90.24-109.75 %).
title: Inflation and Relative Price Dispersion in Canada: An Empirical Assessment
Creators: name: Binette, Andre
name: Martel, Sylvain
Publisher: name: Bank of Canada
Year: 2005

description: The authors investigate empirically the relationship between different aspects of inflation and relative price dispersion in Canada using a Markov regime-switching Phillips curve. They examine three theories that explain movements in relative price dispersion: the signal extraction model, the extension of the signal extraction model, and the menu cost model. The authors show that expected inflation, which is captured by the menu cost model, is the aspect of inflation that is most closely associated with relative price dispersion. Furthermore, this result seems robust to different specifications. The authors, however, cannot completely discard inflation uncertainty (the signal extraction model), especially when using core inflation. They also observe a strong asymmetry regarding the impact of positive and negative unexpected inflation on relative price dispersion using total inflation, but this asymmetry is not observed for core inflation. This suggests that the strong asymmetry arises mainly from the presence of components typically associated with supply shocks, and not from the presence of downward nominal rigidities, as Aarstol (1999) proposes, following Ball and Mankiw (1992a,b).
description: Les auteurs examinent empiriquement la relation entre différents aspects de l'inflation et la dispersion des prix relatifs au Canada en utilisant une courbe de Phillips spécifiée à l'aide d'un modèle de régression markovien. Ils analysent trois théories qui cherchent à expliquer les mouvements dans la dispersion des prix relatifs : le modèle à signaux brouillés, une extension de ce modèle et le modèle à coûts d'étiquetage. Les auteurs montrent que l'inflation anticipée, qui est captée par le modèle à coûts d'étiquetage, est l'aspect de l'inflation lié le plus étroitement à la dispersion des prix relatifs. Qui plus est, ce résultat semble robuste pour différentes spécifications. Toutefois, les auteurs ne peuvent pas rejeter complètement la significativité de l'incertitude (le modèle à signaux brouillés), surtout lorsqu'ils font appel à une mesure de l'inflation tendancielle. Ils constatent aussi que les variations positives et négatives imprévues de l'inflation totale ont des effets très asymétriques sur la dispersion des prix relatifs, mais que cette asymétrie n'est pas observée dans le cas de l'inflation tendancielle. Ce résultat donne à penser que la forte asymétrie découle principalement des composantes typiquement associées à des chocs d'offre, et non pas de la présence de rigidités nominales comme l'avance Aarstol (1999), dans la lignée de Ball et Mankiw (1992a et b).
title: Has Exchange Rate Pass-Through Really Declined in Canada?
Creators: name: Bouakez, Hafedh
name: Rebei, Nooman
Publisher: name: Bank of Canada
Year: 2005

description: Several empirical studies suggest that exchange rate pass-through has declined in recent years in industrialized countries. Results for Canada also indicate that, in the 1990s, import and consumer prices became less responsive to exchange rate movements. These findings are based on reducedform regressions that are typically motivated by partial-equilibrium models of pricing. Bouakez and Rebei instead use a structural, general-equilibrium approach to test the premise that exchange rate pass-through has decreased in Canada. Their approach consists in estimating a dynamic stochastic general-equilibrium model for Canada over two subsamples, which cover the periods before and after the Bank's adoption of inflation targeting. The authors then use impulse-response analysis to assess the stability of exchange rate pass-through across the two subsamples. Their results indicate that pass-through to Canadian import prices has been rather stable, while passthrough to Canadian consumer prices has declined in recent years. Counterfactual experiments reveal that the change in monetary policy regime is largely responsible for this decline.
description: D'après plusieurs études empiriques, l'incidence de l'évolution du taux de change sur les prix a diminué ces dernières années dans les pays industrialisés. Les résultats relatifs au Canada indiquent eux aussi que les prix à l'importation et à la consommation sont devenus moins sensibles aux mouvements du taux de change dans les années 1990. Ces résultats proviennent de la régression de modèles de prix en forme réduite qui reposent généralement sur un cadre d'équilibre partiel. Pour voir si le degré de transmission des variations du taux de change du dollar canadien aux prix a effectivement faibli, Bouakez et Rebei ont plutôt recours à un modèle structurel d'équilibre général dynamique et stochastique, qu'ils estiment pour les périodes antérieure et postérieure à l'adoption d'une cible d'inflation par la Banque du Canada. Ils évaluent ensuite la stabilité du degré de transmission des fluctuations du taux de change au cours de ces deux périodes en ayant recours à une analyse des profils de réaction. Ils constatent que l'incidence des variations du taux de change sur les prix canadiens à l'importation est restée assez stable, mais que leur effet sur les prix à la consommation a baissé ces dernières années. Des simulations contrefactuelles révèlent que cette réduction tient largement au changement de régime de politique monétaire.

title: Pre-Bid Run-Ups Ahead of Canadian Takeovers: How Big Is the Problem?
Creators: name: King, Michael R.
name: Padalko, Maksym
Publisher: name: Bank of Canada
Year: 2005

description: The authors study the price—volume dynamics ahead of the first public announcement of a takeover for 420 Canadian firms from 1985 to 2002. Pre-bid price run-ups in a target firm's shares may be caused by some combination of information leakage due to illegal insider trading or market anticipation based on rumours in the press. The authors review empirical studies of illegal insider trading and trading ahead of unscheduled announcements to generate predictions for abnormal returns and abnormal volume ahead of the takeover announcement. They observe serially correlated volume and a pattern of return reversals in their sample. Pre-bid run-ups occur shortly before the actual announcement, accompanied by significantly positive abnormal returns and share volume. The stock prices of the target firm react significantly to the actual announcement, with both positive and negative reactions. These price–volume dynamics are more consistent with the predictions of the market anticipation hypothesis than the hypothesis of illegal insider trading.
description: Les auteurs examinent la manière dont évoluent le cours des actions et le volume des transactions àà l'approche d'une offre publique d'achat (OPA); leur échantillon englobe 420 entreprises canadiennes ayant été l'objet de telles opérations entre 1985 et 2002. Les hausses de cours qui précèdent une OPA peuvent être dues àà une fuite d'information résultant d'opérations d'initié illicites et/ou àà des anticipations du marché liées àà des rumeurs véhiculées dans les médias. Prenant appui sur les résultats empiriques de chercheurs ayant analysé des délits d'initié et l'évolution du volume des transactions àà l'approche d'annonces imprévues, les auteurs génèrent une prévision des rendements et des volumes anormaux susceptibles d'être observés avant la première annonce publique d'une OPA. Ils constatent une autocorrélation du volume des transactions et un renversement de tendance dans les rendements durant la période étudiée. Le cours de l'action grimpe peu avant l'annonce proprement dite, et tant les rendements anormaux que les volumes anormaux sont significativement supérieurs àà zéro. Le prix de l'action de l'entreprise visée réagit de façon significative àà l'OPA, aussi bien àà la hausse qu'àà la baisse. Cette évolution des cours et des volumes semble davantage tenir àà des anticipations du marché qu'àà des fuites d'information découlant de délits d'initié.
Mining in a Sacred Landscape: Adivasis, Deities and Alliances in a Former Princely State in Odisha/India
Creators: name: Skoda, Uwe
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

The papers explores ideas of a sacred landscape inhabited by indigenous people as well as other communities, deities as well as other beings manifested in localities and ‘objects’ forming various relationships, alliances and a thick web of relationality in a former kingdom in central-eastern India. It introduces these historically evolved ties through the foundational narratives as well as contemporary rituals, while the area is undergoing major transformations after Indian independence and even more so in a phase of accelerated industrialisation, especially tied to a mining boom and sponge iron factories. The latter not only threatens to uproot an existing, though changing sacrificial polity around local deities, but it also has massive ecological consequences and leads to partially successful protests.

description:

This article proposes a sensory approach to physical and representational environments based on a pedestrian perspective. With a view to bringing arts-based considerations to bear on UN Sustainable Development Goal 6.6, concerned with the protection and restoration of water-related ecosystems, the analysis primarily revolves around Italian and French depictions of Venice in the 1880s-1890s that encompass stimuli for smell, sound, taste, and touch as much as sight. Close readings are undertaken to highlight hyperlocal elements that merit consideration when determining courses of action for the long-term good of the lagoonscape.

description:

The present essay relates to a line of enquiry that focuses on the Islamic contribution to the values held in common by different cultural traditions, with the aim of working towards a shared ethical conscience and peaceful coexistence in the cities of a globalised world. The essay emphasises cultural specificities, starting with the terminology currently used to describe environmentalism and sustainability. Drawing on the works of a number of contemporary Arab Muslim intellectuals, my enquiry aims to look at environmental sustainability from an Islamic perspective, and to address it as part of the ethical heritage of Islam.

Self Calibration in Cluster Studies of Dark Energy: Combining the Cluster Redshift Distribution, the Power Spectrum and Mass Measurements
Creators: name: Majumdar, Subhabrata
name: Mohr, Joseph J.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We examine the prospects for measuring the dark energy equation of state parameter w within the context of any uncertain redshift evolution of galaxy cluster structure (building on Majumdar and Mohr, 2003) and show that including the redshift averaged cluster power spectrum, P_cl(k), and direct mass measurements of 100 clusters helps tremendously in reducing cosmological parameter uncertainties. Specifically, we show that when combining the redshift distribution and the power spectrum information for a particular X-ray survey (DUET) and two SZE surveys (SPT & Planck), the constraints on the dark energy equation of state w can be improved by roughly a factor of 4. Because surveys designed to study the redshift distribution of clusters will have all the information necessary to construct P_cl(k), the benefit of adding P_cl(k) in reducing uncertainties comes at no additional observational cost. Combining detailed mass studies of 100 clusters with the redshift distribution improves the parameter uncertainties by a factor of 3-5. The data required for these detailed mass measurements-- assumed to have 1sigma uncertainties of 30-- are accumulating in the the XMM-Newton and Chandra archives. The best constraints are obtained when one combines both the power spectrum constraints and mass measurements with the cluster redshift distribution; when using the survey to extract the parameters and evolution of the mass--observable relations, we estimate the uncertainties on w of ~4% to 6%. These parameter constraints are obtained from self-calibrating cluster surveys alone. In combination with CMB or distance measurements that have different parameter degeneracies, cluster studies of dark energy will provide enhanced constraints and allow for cross--checks of systematics.

Noise level estimation of time series using coarse grained entropy

Year: 2003

description: We present a method of noise level estimation that is valid even for high noise levels. The method makes use of the functional dependence of coarse grained correlation entropy $K_2(\eps)$ on the threshold parameter $\eps$. We show that the function $K_2(\eps)$ depends in a characteristic way on the noise standard deviation $σ$. It follows that observing $K_2(\eps)$ one can estimate the noise level $σ$. Although the theory has been developed for the gaussian noise added to the observed variable we have checked numerically that the method is also valid for the uniform noise distribution and for the case of Langevine equation corresponding to the dynamical noise. We have verified the validity of our method by applying it to estimate the noise level in several chaotic systems and in the Chua electronic circuit contaminated by noise.

description: Graphene adsorption on Au(111) surface was explored to identify their common surface structures by means of van der Waals corrected density functional theory calculations. The alignment of graphene in the form of certain rotational angles on the gold surface has an important role on the lattice matching which causes Moiré patterns, and on the electronic properties of the resulting common cell structures. The dispersive weak interactions between carbon and gold layers lead to a downward shift of Fermi energy of the adsorption system with respect to the Dirac point of graphene showing a $p$-type doping character. Moreover, the shift was shown to depend on the rotational angle of graphene on Au(111).

Does land fragmentation affect farm performance? A case study from Brittany

description: Agricultural land fragmentation is widespread and may affect farmers’ decisions and impact farm performance, either negatively or positively. We investigated this impact for the western region of Brittany, France, in 2007. To do so, we regressed a set of performance indicators on a set of fragmentation descriptors. The performance indicators (production costs, yields, revenue, profitability, technical and scale efficiency) were calculated at the farm level using Farm Accountancy Data Network (FADN) data, while the fragmentation descriptors were calculated at the municipality level using data from the cartographic field pattern registry (RPG). The various fragmentation descriptors enabled us to account for not only the traditional number and average size of plots, but also their geographical scattering. We found that farms experienced higher costs of production, lower crop yields and lower profitability where land fragmentation (LF) was more pronounced. Total technical efficiency was not found to be significantly related to any of the municipality LF descriptors used, while scale efficiency was lower where the average distance to the nearest neighbouring plot was greater. Pure technical efficiency was found to be negatively related to the average number of plots in the municipality, with the unexpected result that it was also positively related to the average distance to the nearest neighbouring plot. By simulating the impact of hypothetical consolidation programmes on average pre-tax profits and wheat yield, we also showed that the marginal benefits of reducing fragmentation may differ with respect to the improved LF dimension and the performance indicator considered. Our analysis therefore shows that the measures of land fragmentation usually used in the literature do not reveal the full set of significant relationships with farm performance and that, in particular, measures accounting for distance should be considered more systematically.

description: This paper assesses the complex interplay between global Renewable Energy Directives (RED) and the United Nations programme to Reduce Emissions from Deforestation and forest Degradation (REDD). We examine the interaction of the two policies using a scenario approach with a recursive-dynamic global Computable General Equilibrium model. The consequences of a global biofuel directive on worldwide land use, agricultural production, international trade flows, food prices and food security out to 2030 are evaluated with and without a strict global REDD policy. We address a key methodological challenge of how to model the supply of land in the face of restrictions over its availability, as arises under the REDD policy. The paper introduces a flexible land supply function, which allows for large changes in the total potential land availability for agriculture. Our results show that whilst both RED and REDD are designed to reduce emissions, they have opposing impacts on land use. RED policies are found to extend land use whereas the REDD policy leads to an overall reduction in land use and intensification of agriculture. Strict REDD policies to protect forest and woodland lead to higher land prices in all regions. World food prices are slightly higher overall with some significant regional increases, notably in Southern Africa and Indonesia, leading to reductions in food security in these countries. This said, real food prices in 2030 are still lower than the 2010 level, even with the RED and REDD policies in place. Overall this suggests that RED and REDD are feasible from a worldwide perspective, although the results show that there are some regional problems that need to be resolved. The results show that countries directly affected by forest and woodland protection would be the most economically vulnerable when the REDD policy is implemented. The introduction of REDD policies reduces global trade in agricultural products and moves some developing countries to a net importing position for agricultural products. This suggests that the protection of forests and woodlands in these regions reverses their comparative advantage as they move from being land-abundant to land-scarce regions. The full REDD policy setting, however, foresees providing compensation to these countries to cover their economic losses.
title: Intertemporal Substitution in Macroeconomics: Evidence from a Two-Dimensional Labour Supply Model with Money
Creators: name: Dib, Ali

Publisher: name: Bank of Canada
Year: 2005

description: The hypothesis of intertemporal substitution in labour supply has a history of empirical failure when confronted with aggregate time-series data. The authors show that a two-dimensional labour supply model, adapted to an environment with money as originally proposed by Lucas and Rapping (1969) and Lucas (1972), performs very well. The overidentifying restrictions implied by the model are far from rejected. The estimated parameters of preferences are generally stable and meaningful. Furthermore, the estimated wage elasticities of labour supply are much higher than previously found in the literature.
description: La confrontation empirique avec les séries chronologiques macroéconomiques aboutit habituellement à une réfutation de l'hypothèse de substitution intertemporelle d'offre de travail. Les auteurs montrent qu'un modèle bidimensionnel d'offre de travail avec monnaie, tel que celui proposé par Lucas et Rapping (1969) et Lucas (1972), donne d'excellents résultats. Les contraintes de suridentification qu'implique le modèle ne sont pas rejetées par les données, et les estimations des paramètres relatifs aux préférences sont généralement stables et sensées. De plus, les valeurs calculées pour l'élasticité de substitution intertemporelle de l'offre de travail par rapport aux variations temporaires des taux de salaire sont très supérieures à celles que l'on trouve dans la littérature.

description: The authors investigate whether the aggregation of region-specific forecasts improves upon the direct forecasting of Canadian GDP growth. They follow Marcellino, Stock, and Watson (2003) and use disaggregate information to predict aggregate GDP growth. An array of multivariate forecasting models are considered for five Canadian regions, and single-equation models are considered for direct forecasting of Canadian GDP. The authors focus on forecasts at 1-, 2-, 4-, and 8-quarter horizons, which best represent the monetary policy transmission framework of long and variable lags. Region-specific forecasts are aggregated to the country level and tested against aggregate country-level forecasts. The empirical results show that Canadian GDP growth forecasts can be improved by indirectly forecasting the GDP growth of the Canadian economic regions using a multivariate approach, namely a vector autoregression and moving average with exogenous regressors (VARMAX) model.
description: Les auteurs cherchent à déterminer si l'agrégation de prévisions régionales permet d'améliorer la prévision de la croissance du PIB canadien. Suivant l'exemple de Marcellino, Stock et Watson (2003), ils utilisent des données désagrégées pour prédire la croissance globale du PIB. Ils appliquent une série de modèles multivariés à la prévision du PIB de cinq régions canadiennes et des modèles à une équation à celle du PIB national. Les horizons de un, deux, quatre et huit trimestres retenus par les auteurs correspondent bien aux décalages longs et variables qui caractérisent le mécanisme de transmission de la politique monétaire. Les prévisions régionales sont regroupées à l'échelle nationale, puis comparées à celles obtenues pour l’ensemble du pays au moyen des données globales. D'après les résultats empiriques, il est possible d'améliorer les prévisions de l'évolution du PIB canadien en déterminant indirectement la progression future du PIB des régions économiques du Canada à l'aide d'un modèle vectoriel autorégressif multivarié à moyenne mobile et à régresseurs exogènes (VARMAX).

description: Motivated by the observed discrepancy between the strong spatial correlations of Lyman break galaxies (LBGs) and their velocity dispersions, we consider a theoretical model in which these starbursting galaxies are associated with dark matter halos that experience appreciable infall of material. We show using numerical simulation that selecting halos that substantially increase in mass within a fixed time interval introduces a ``temporal bias'' which boosts their clustering above that of the underlying population. If time intervals consistent with the observed LBGs star formation rates of 50 solar masses per year are chosen, then spatial correlations are enhanced by up to a factor of two. These values roughly correspond to the geometrical bias of objects three times as massive. Thus, it is clear that temporal biasing must be taken into account when interpreting the properties of Lyman break galaxies.

description: LiNiO2 has high energy density but easily reacts with moisture in the atmosphere and deteriorates. We performed qualitative and quantitative evaluations of the degraded phase of LiNiO2 and the influence of the structural change on the electrochemical properties of the phase. Li1-xHxNiO2 phase with cation exchange between Li+ and H+ was confirmed by thermogravimetric analysis and Karl Fischer titration measurement. As the H concentration in LiNiO2 increased, the rate capability deteriorated, especially in the low-temperature range and under low state of charge. Experimental and density functional theory (DFT) calculation results suggested that this outcome was due to increased activation energy of Li+ diffusion owing to cation exchange. Rietveld analysis of X-ray diffraction and DFT calculation confirmed that the c lattice parameter and Li-O layer reduced because of the Li+/H+ cation exchange. These results indicate that LiNiO2 modified in the atmosphere has a narrowed Li-O layer, which is the Li diffusion path, and the rate characteristics are degraded.

description: This working paper provides a comparative analysis, among selected EU member states, of the investment demand of a sample of specialised field crop farms for farm buildings, machinery and equipment as determined by different types and levels of Common Agricultural Policy support. It allows for the existence of uncertainty in the price of output farmers receive and for both long- and short-run determinants of investment levels, as well as for the presence of irregularities in the cost adjustment function due to the existence of threshold-type behaviours. The empirical estimation reveals that three investment regimes are consistently identified in Germany and Hungary, across asset and support types, and in France for machinery and equipment. More traditional disinvestment-investment type behaviours characterise investment in farm building in France and the UK, across support types, and Italy for both asset classes under coupled payments. The long-run dynamic adjustment of capital stocks is consistently and significantly estimated to be towards a – mostly non-stationary – lower level of capitalisation of the farm analysed. By contrast, the expected largely positive short-run effects of an increase in output prices are often not significant. The effect of CAP support on both types of investment is positive, although seldom significant, while the proxy for uncertainty employed fails to be significant yet, in most cases, has the expected effect of reducing the investment levels.
title: Degree of Internationalization and Performance: An Analysis of Canadian Banks

Year: 2005

description: The international business literature measures the link between the degree of internationalization (DOI) of a firm's activities and its performance. The results of this literature are mixed. The authors extend the analysis to Canadian bank-level data, but they also take into account the riskiness of each bank's foreign-asset exposure. The results establish a positive, but weak, relationship between DOI and performance—one that is dependent on each bank's risk profile. The authors discuss the policy implications of their analysis.
description: Des études sur le commerce international mesurent le lien entre le degré d'internationalisation des activités d'une entreprise et ses résultats. Les conclusions de ces études sont partagées. Les auteurs reprennent cette analyse à l'aide de données relatives aux banques canadiennes, tout en tenant compte du risque associé aux créances sur l'étranger que détient chacune des banques. Les auteurs concluent à l'existence d'une relation positive, quoique faible, entre le degré d'internationalisation et les résultats — relation qui dépend du profil de risque propre à chaque banque — et traitent des implications de ce constat pour les politiques publiques.

description: While recent studies emphasize the importance of firm heterogeneous effects in understanding international trade and its gains, these insights have largely been ignored in the literature on standards. In this paper we analyze how the adoption of private food standards by individual firms affects their export performance at the intensive and extensive margins of trade. We use unique 18-year panel data from 95 asparagus export firms in Peru and apply fixed effects and system GMM models. Results indicate that, when export persistence, unobserved heterogeneity and reversed causality are controlled for, certification to private standard schemes does not improve firms’ propensity to export, nor their export volumes and values. This insight puts doubt on the effectiveness of development programs to support developing country exporters to comply with private food standards in order to maintain or improve international market access.

description: It is shown that flat zero-energy solutions (vacua) of the 5d Kaluza-Klein theory admit a non-trivial homotopy structure generated by certain Kaluza-Klein excitations. These vacua consist of an infinite set of homotopically different spacetimes denoted by $\mathcal{M}^{(n)}_5$, among which $\mathcal{M}^{(0)}_5$ and $\mathcal{M}^{(1)}_5$ are especially identified as $M_{4} \times S^{1}$ and $M_5$, the ground states of the 5d Kaluza-Klein theory and the 5d general relativity, respectively (where $M_k$ represents the $k$-dimensional Minkowski space).

description: We show that the quantum many-body state of Bose-Einstein condensates (BEC) consistent with the time-dependent Hartree-Fock-Bogoliubov (TDHFB) equations is a generalized coherent state (GCS). At zero temerature, the non-condensate density and the anomalous non-condensate correlation are not independent, allowing us to elimiate one of the three variables in the TDHFB.

description: The effects of global climate change on agriculture will be diverse and complex. Some important qualitative conclusions emerge from the literature. First, it is important to focus on the rate at which climate changes and the capacity of farmers to adjust, rather than on absolute changes in temperature. Second, given that significant warming is inevitable, it is important to focus on the marginal effects of feasible changes in the rate of warming, rather than on the aggregate rate of warming. With a convex damage function, the expected marginal cost of warming may be large even when aggregate damage, given the expected rate of warming, is close to zero. Third, uncertainty is crucial and remains poorly understood. In particular, modelling of low-probability catastrophic outcomes remains very limited. Finally, it seems likely that global climate change will enhance extremes of all kinds.
