In monetary unions, monetary policy is typically made by delegates of the member countries. This procedure raises the possibility of strategic delegation - that countries may choose the types of delegates to influence outcomes in their favor. We show that without commitment in monetary policy, strategic delegation arises if and only if three conditions are met: shocks affecting individual countries are not perfectly correlated, risk-sharing across countries is imperfect, and the Phillips Curve is nonlinear. Moreover, inflation rates are inefficiently high. We argue that ways of solving the commitment problem, including the emphasis on price stability in the agreements constituting the European Union are especially valuable when strategic delegation is a problem.

We reformulate the Smets-Wouters (2007) framework by embedding the theory of unemployment proposed in Galí (2011a,b). Weestimate the resulting model using postwar U.S. data, while treatingthe unemployment rate as an additional observable variable. Our approach overcomes the lack of identification of wage markup and laborsupply shocks highlighted by Chari, Kehoe and McGrattan (2008) intheir criticism of New Keynesian models, and allows us to estimate a"correct" measure of the output gap. In addition, the estimated modelcan be used to analyze the sources of unemployment fluctuations.

Autoimmune Pancreatitis (AIP) is a new nosological entity that was first reported by Sarles et al. in 1961 and then named by Yoshida et al. in 1995 in Japan. It was then ignored by many Western researchers and now, in the last decade; it appears to have been recognized worldwide. AIP is a distinct form a chronic pancreatitis with an immune mediated fibroinflammatory process that has unique histopathologic features that makes it distinguishable from other forms of pancreatitis. Moreover, AIP is the only type of pancreatitis that responds to steroid administration. The Honolulu consensus document that has recently been published by Chari et al. described the histopathologic and clinical subtypes of AIP. Indeed, it appears that there are two forms of AIP, with different prevalence in Europe and Asia and distinct clinical profiles. The first subtype, the most common type in Asia, has recently been named Lymphoplasmocytic sclerosing pancreatitis (LPSP) or type I AIP because of its histological features and its association with elevated IgG serum levels and various autoantibodies. The second one is called idiopathic duct centric pancreatitis, IDCP, or type II AIP, that barely exists in Japan, but more accounted in Caucasian people. IDCP is recognized by its particular histology that is a granulocytic epithelial lesion (GEL) which makes some people call it AIP with GEL. Still nowadays, the diagnosis of AIP is a challenge. AIP can only be definitively diagnosed by histological examination. The main differential diagnosis of AIP is, except chronic pancreatitis, pancreatic cancer. That explains why there are still some unnecessary resections. Several groups have proposed diagnostic criteria for AIP as in Japan, Korea, Germany, Italy and the United States. Thus, it is important to find an international consensus. Above all, it is important to find new criteria as specific markers in the serum and the pancreatic tissues, for example using proteomics, to be able to diagnosis both types of AIP, and distinguish AIP from pancreatic cancer in order to avoid surgical resection in patients with AIP. The aim of this project is to review all relevant studies about AIP and to document all the available diagnostic tools.

Suite à la crise financière globale de 2008, ainsi qu’aux différents facteurs qui y ont mené, il est étonnant qu’une alternative éthique et juste pour une finance lucrative et stable n’existe toujours pas (ou du moins, demeure oubliée). Ayant décidé de contribuer au domaine pluri-centenaire du Droit Commercial de la Chari’a, nous avons été surpris par la découverte d’une problématique à l’origine de cette thèse. En France, nous avons suivi des débats doctrinaux intéressants dont les conclusions se rapprochent de la perception générale Occidentale quand à la nature de la finance Islamique, que ce soit au niveau de la finance basée sur le Droit de la Chari’a ou encore les exigences de sa pleine introduction dans le système juridique français de l’époque. Cet intérêt initial dans la finance islamique a ensuite mené à un intérêt dans la question des avantages d’éthique et de justice du Droit Commercial de la Chari’a dans son ensemble, qui est au coeur de cette thèse. Dans le monde moderne du commerce et de la finance d’aujourd’hui, les transactions sont marquées par une prise de risque excessive et un esprit de spéculation qui s’apparente aux jeux de hasard, et menant à des pertes colossales. Pire encore, ces pertes sont ensuite transférées à la collectivité. Par conséquent, y at-il des préceptes, des principes ou des règles éthiques et juridiques qui peuvent fournir une certaine forme de sécurité et de protection dans les marchés financiers d'aujourd'hui? Est-ce réalisable? Cette thèse soutient que la richesse de la jurisprudence islamique ainsi que ses règles dont les avantages n’ont pas encore été pleinement saisis et régénérés en réponse aux nouveaux défis d’aujourd'hui, peuvent encore fournir continuellement des solutions, et réformer des produits financiers de façon à refléter des principes de justice et d'équité. Dans ce processus, un éclairage nouveau sera apporté à certains sujets déjà connus dans le cadre de la contribution prévue de cette thèse, mais ne sera pas le principal objectif de la thèse.

Durante los últimos años los enseñantes se han encontrado con una serie de retos que nunca se habrían imaginado. La experiencia qeu se expone en el artículo es la de un IES en el que se integraron alumnos sordos en modalidad bilingüe. Las estrategias didácticas y las técnicas utilizadas se comentan para dar fe de los buenos resultados de esta experiencia.

One may construct, for any function on the integers, an irreducible module of level zero for affine sl(2) using the values of the function as structure constants. The modules constructed using exponential-polynomial functions realize the irreducible modules with finite-dimensional weight spaces in the category (O) over tilde of Chari. In this work, an expression for the formal character of such a module is derived using the highest weight theory of truncations of the loop algebra.
