Interest Term Premiums and C-CAPM: A Test of a Parsimonious Model

This paper proposes a consumption-based model that accounts for term premiums of the nominal term structure of interest rates. The driving force behind the model is the looking at the ex ante term premium. Nominal term premiums depend on the volatility processes of real consumption and inflation. When calibrated to US data on interest rates, consumption and inflation, the model accounts for the C-CAPM expectations puzzle. Risk aversion coefficients around 6 are evidenced. The hypothesis of non-constant subjective discount rates is envisaged but successfully validated.C-CAPM, term structure of interest rates, term premium, risk aversion, subjective discount factor

Aging mechanism in tunable Pickering emulsion

We study the stability of a model Pickering emulsion system. A special counter-flow microfluidics set-up was used to prepare monodisperse Pickering emulsions, with oil droplets in water. The wettability of the monodisperse silica nanoparticles (NPs) could be tuned by surface grafting and the surface coverage of the droplets was controlled using the microfluidics setup. A surface coverage as low as 23$\%$ is enough to stabilize the emulsions and we evidence a new regime of Pickering emulsion stability where the surface coverage of emulsion droplets of constant size increases in time, in coexistence with a large amount of dispersed phase. Our results demonstrate that the previously observed limited coalescence regime where surface coverage tends to control the average size of the final droplets must be put in a broader perspective

Leveraging FAIR Signposting & RO-Crate for the Norwegian Research Data Archive

Lightning talk given during the 1st workshop organised by FAIR-Impact on the framework on the half day virtual workshop on "Enabling FAIR Signposting and RO-Crate". This presentation briefly explains what our goals are and what support we need to fulfil our task

A sampling method for estimating the accuracy of predicted breeding values in genetic evaluation

A sampling-based method for estimating the accuracy of estimated breeding values using an animal model is presented. Empirical variances of true and estimated breeding values were estimated from a simulated n-sample. The method was validated using a small data set from the Parthenaise breed with the estimated coefficient of determination converging to the true values. It was applied to the French Salers data file used for the 2000 on-farm evaluation (IBOVAL) of muscle development score. A drawback of the method is its computational demand. Consequently, convergence can not be achieved in a reasonable time for very large data files. Two advantages of the method are that a) it is applicable to any model (animal, sire, multivariate, maternal effects...) and b) it supplies off-diagonal coefficients of the inverse of the mixed model equations and can therefore be the basis of connectedness studies

Measuring connectedness among herds in mixed linear models: From theory to practice in large-sized genetic evaluations

A procedure to measure connectedness among groups in large-sized genetic evaluations is presented. It consists of two steps: (a) computing coefficients of determination (CD) of comparisons among groups of animals; and (b) building sets of connected groups. The CD of comparisons were estimated using a sampling-based method that estimates empirical variances of true and predicted breeding values from a simulated n-sample. A clustering method that may handle a large number of comparisons and build compact clusters of connected groups was developed. An aggregation criterion (Caco) that reflects the level of connectedness of each herd was computed. This procedure was validated using a small beef data set. It was applied to the French genetic evaluation of the beef breed with most records and to the genetic evaluation of goats. Caco was more related to the type of service of sires used in the herds than to herd size. It was very sensitive to the percentage of missing sires. Disconnected herds were reliably identified by low values of Caco. In France, this procedure is the reference method for evaluating connectedness among the herds involved in on-farm genetic evaluation of beef cattle (IBOVAL) since 2002 and for genetic evaluation of goats from 2007 onwards

Pierre Deffontaines, Journal de guerre (1939-1944). Présenté et annoté par Isabelle Lostanlen, préface de Claude Hauser

Le géographe Pierre Deffontaines, élève de Jean Brunhes (et non Bruhnes...), a dirigé l’Institut français de Barcelone de sa réouverture en octobre 1939 jusqu’à sa retraite en 1964. Sa femme et lui ont tenu un « Livre de raison » pour noter des événements intimes, mais aussi les répercussions de l’air du temps sur leur vie de famille. S’il couvre l’ensemble de leur existence, I. L. n’en retient que la période fort agitée de la Seconde Guerre mondiale. On y découvre comment un maréchaliste de ..

Avant-propos

La présente livraison des Cahiers d'histoire est consacrée, pour l'essentiel, au fait chrétien en France et plus particulièrement dans la région Rhône-Alpes, aux époques moderne et contemporaine. Un tel choix n'a rien d'une innovation. Pour son trentième anniversaire en effet, la revue publiait, voici plus de dix ans, un petit fascicule intitulé : " L'histoire religieuse dans les Cahiers d'histoire ". Celui-ci n'énumérait pas moins de quatre numéros spéciaux et de cent articles consacrés au m..

Denis Pelletier, Jean-Louis Schlegel (Dir.), À la gauche du Christ. Les chrétiens de gauche en France de 1945 à nos jours

Il existe un mouvement missionnaire dans les zones déchristianisées de Belgique wallonne après la Libération, mais guère de volonté de collaboration catholique avec un mouvement communiste faible. Au contraire en Italie, qui reste largement un pays de chrétienté, pas de mouvement missionnaire, mais une tentation communiste parmi les intellectuels et les militants refusant l’hégémonie de la Démocratie chrétienne. La France est le seul pays d’Europe occidentale dans lequel se conjuguent, sous l..
